Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure relates to a hard disk drive (HDD)
holder.
[0003] 2. Description of Related Art
[0004] An HDD holder is used to hold an HDD. The HDD holder
typically includes a main body and a handle having opposite first
and second ends, wherein the first end is rotatably mounted to the
main body, a locking tongue extends from the first end, and a hook
extends from the second end. A computer chassis typically includes
a receiving portion for receiving the HDD holder. The receiving
portion includes opposite sidewalls for mounting the HDD holder
therebetween, wherein one of the sidewalls defines a locking hole.
When the HDD holder is received in the receiving portion, the
handle is rotated to the main body to be closed. The hook of the
handle will hook the main body of the HDD holder, and the locking
tongue will extend in the locking hole of the receiving portion.
Therefore, the HDD holder can be securely locked in the receiving
portion successfully. However, when the receiving portion is
manufactured, there is usually an error of a distance between the
sidewalls of the receiving portion, which may lead the locking
tongue of the handle cannot be locked in the locking hole of the
receiving portion.
[0005] In order to solve the above-mentioned problem, a new frame
appears in industry to improve the HDD holder. In the new frame,
the locking tongue is elastically mounted to the first end of the
handle, and thereby the distance error of the sidewalls of the
receiving portion can be offset. However, this new frame causes a
new problem that the hook of the handle can hook the main body of
the HDD holder no matter the locking tongue extends in the locking
hole or abuts against the corresponding sidewall of the receiving
portion. In other words, when the HDD holder is received in the
receiving portion, if the HDD holder is not located at the right
position to be locked, the handle can still be closed, which will
misguide a user to think that the installation of the HDD holder
has already been done. Under this misguided thought, when the user
operates or turns the receiving portion, the HDD may fall off the
receiving portion and the HDD may be damaged.

is located between the third pivoting hole 335 and the right end
331 of the covering board 33.
[0022] The hook 50 includes a post 51. A pivoting pole 52 extends
from each of top and bottom ends of the post 51. A hooking portion
53 and an operating portion 54 extend from a circumference of the
post 51. An extending direction of the operating portion 54 is
perpendicular to an extending direction of the hooking portion 53.
A hooking block 56 and a projection 55 extend from the hooking
portion 53, opposite to the operating portion 54. The projection 55
is located between the hooking block 56 and the post 51. The
hooking block 56 includes a slanting guiding surface 560.
[0023] In the present embodiment, the third elastic member 40 is a
torsion spring.
[0024] In assembling the HDD holder 8, the second elastic member 90
is fitted around the raised portion 221 of the main body 10. The
first elastic member 80 is fitted around the guiding post 71 of the
sleeve 70. The sleeve 70 is disposed between the raised portion 221
of the main body 10 and the top board 21, and a free end of the
guiding post 71 is extended through the guiding hole 230 of the
projecting piece 231, to sandwich the first elastic member 80
between the projecting piece 231 and the sleeve 70. The first
extension piece 31 of the handle 30 is disposed on the top board 21
of the main body 10, with the first pivot hole 313 of the handle 30
aligning with the first elongated hole 210, and the second
extension piece 32 of the handle 30 is disposed under the bottom
board 22 of the main body 10, with the second pivot hole 324 of the
handle 30 aligning with the second elongated hole 220. The first
pivot hole 313 and the second pivot hole 324 of the handle 30, the
first elongated hole 210 and the second elongated hole 220 of the
main body 10, and the sleeve hole 700 of the sleeve 70 are adjusted
to be aligned, and cooperatively receive the spindle 60. It is
noted that the first segment 61 of the spindle 60 is received in
the first pivot hole 313 of the handle 30 and the first elongated
hole 210 of the main body 10, and an engagement between the first
segment 61 and the first pivot hole 313 and an engagement between
the first segment 61 and the first elongated hole 210 are clearance
fit; the second segment 62 of the spindle 60 is received in the
sleeve hole 700 of the sleeve 70, and an engagement between the
second segment 62 and the sleeve hole 700 is interference fit; the
third segment 63 of the spindle 60 is received in the second
elongated hole 220 of the main body 10 and the second pivot hole
324 of the handle 30, and an engagement between the third segment
63 and the second elongated hole 220 and an engagement between the
third segment 63 and the second pivot hole 324 are clearance fit.
The third elastic member 40 is fitted about the post 51 of the hook
50, adjacent to the bottom end of the post 51. The pivoting poles
52 of the hook 50 are pivotably received in the corresponding third
pivot holes 335 of the handle 30, and the projection 55 of the hook
50 abuts against the blocking piece 36 of the handle 30, under the
elastic force of the third elastic member 40. It is noted that
opposite ends of the first elastic member 80 abut against the
projecting piece 231 of the main body 10 and the sleeve 70
respectively, two spring legs of the second elastic member 90 abut
against the main body 10 and the handle 30 respectively, and two
spring legs of the third elastic member 40 abut against the hooking
portion 53 of the hook 50 and the handle 30 respectively and supply
the elastic force of the third elastic member 40 to bias the
hooking portion 53 to rotate towards the blocking piece 36 of the
handle 30. The blocking piece 36 of the handle 30 is configured to
prevent the hooking portion 53 from rotating too much.
[0025] Referring to FIG. 4, in normal use of the HDD holder 8, the
handle 30 is opened relative to the main body 10 via rotating
around the spindle 60 (FIG. 4 shows the handle being closed). The
HDD holder 8 is slid into a receiving portion 4 of a computer
chassis, to completely receive the HDD holder 8 in the receiving
portion 4. The handle 30 is rotated to the main body 10 to be
closed. When the handle 30 is rotated to the main body 10, the
guiding surface 560 of the hooking block 56 of the hook 50 contacts
a corresponding end of the second connecting wall 24 of the main
body 10, and under the elastic force of the third elastic member
40, the hooking block 56 goes over the corresponding end of the
second connecting wall 24 via an engagement between the guiding
surface 560 and the corresponding end of the second connecting wall
24, to extend in the hooking hole 240 of the second connecting wall
24 to hook the second connecting wall 24. The locking tongues 34 of
the handle 30 extend into a locking hole 7 of a first sidewall 5 of
the receiving portion 4, the first extension piece 31 and the
second extension piece 32 of the handle 30 abut against an inner
side of the first sidewall 5, and the second elastic member 90 is
elastically deformed. Therefore, the HDD holder 8 is locked between
the first sidewall 5 and a second sidewall 6 opposite to the first
sidewall 5 of the receiving portion 4. It is noted that the first
elastic member 80 supplies an elastic force to bias the sleeve 70
together with the spindle 60 and the handle 30 to right dead ends
of the first elongated hole 210 and the second elongated hole
220.
[0026] In uninstalling the HDD holder 8, the operating portion 54
of the hook 50 is pressed towards the left end 332 of the handle 30
to disengage the hooking block 56 of the hook 50 from the hooking
hole 240 of the main body 10. Therefore, an elastic force of the
second elastic member 90 can bias the handle 30 to rotate away from
the main body 10 and thereby opening the handle 30. The locking
tongues 34 of the handle 30 disengage from the locking hole 7 of
the first sidewall 5 of the receiving portion 4. Therefore, the HDD
holder 8 is ready to be removed from the receiving portion 4. It is
noted that the projection 212 of the top board 21 of the main body
10 is configured to limit a rotation angle of the handle 30. When
the handle 30 is opened, the first extension piece 31 will be
blocked by the projection 212, such that the rotation angle of the
handle 30 is limited between about 0-30 degrees.
[0027] In practice, a distance between the first and second
sidewalls 5 and 6 of the receiving portion 4 usually has an error
between plus or minus 1 millimeter (the error range is much less
than lengths of the first elongated hole 210 and the second
elongated hole 220). The handle 30 of the present disclosure is
able to slide under the force of the first elastic member 80, such
that the locking tongues 34 of the handle 30 is able to elastically
engage in the locking hole 7 of the receiving portion 4 no matter
how much distance between the first and second sidewalls 5 and 6 of
the receiving portion 4. Therefore, the error of the distance can
be offset.
[0028] Referring to FIG. 5, the present disclosure has an
innovative function that if the HDD holder 8 is not completely slid
in the receiving portion 4, the handle 30 can not be closed, which
is actually an alarm and can lead the user to assuredly push the
HDD holder 8 in position to be locked. In detail, when the HDD
holder 8 is not completely slid in the receiving portion 4, if the
handle 30 is tried to be closed by the user, the locking tongues 34
of the handle 30 will engage with the first sidewall 5 of the
receiving portion 4 and be compelled to move leftward. The handle
30 together with the hook 50 will slide leftward under the guiding
of the first elongated hole 210 and the second elongated hole 220,
wherein the spindle 60 is slid to left dead ends of the first
elongated hole 210 and the second elongated hole 220. Therefore,
the hooking block 56 of the hook 50 will be completely located at
the left side of second connecting wall 24 of the main body 10 and
cannot engage in the hooking hole 240 of the second connecting wall
24. Once the operation of the user stops, the handle 30 will be
rotated away from the main body 10 by the second elastic member 90
to be opened. Accordingly, the present disclosure can prevent the
user from making mistakes and thereby preventing the HDD holder 8
from been damaged by accident.
[0029] In other embodiments, the engagement between the spindle 60
and the sleeve 70 may be clearance fit, and the engagement(s)
between the spindle 60 and the first pivot hole 313 and/or the
second pivot hole 324 of the handle 30 may be interference fit.
[0030] In other embodiments, the first elastic member 80 may be a
torsion spring whose two spring legs abut against the main body 10
and the sleeve 70, respectively. Another round raised portion like
the raised portion 221 may extend from the main body 10 for the
torsion spring to fit about.
[0031] In other embodiments, the sleeve 70 may be omitted, and the
guiding post 71 may extend from the spindle 60. Furthermore, the
guiding post 71 may be omitted, and a first portion of the spindle
60 that engages in the first elongated hole 210 and/or a second
portion of the spindle 60 that engages in the second elongated hole
220 may be designed to have rectangular cross section to make the
spindle 60 be slidable and not pivotable. If the guiding post 71 is
omitted, the first elastic member 80 may be positioned in other
ways. For example, a sleeve defining a through hole may be
disposed, and the first elastic member 80 is received in the
through hole with the opposite ends of the first elastic member 80
extending out of the through hole.
[0032] In other embodiments, the second elastic member 90 may be a
pressure spring whose opposite ends abut against the main body 10
and the handle 30 respectively.
[0033] In other embodiments, the third elastic member 40 may be a
pressure spring whose opposite ends abut against the operating
portion 54 of the hook 50 and the handle 30, respectively. The
third elastic member 40 may also be an extension spring whose
opposite ends connect with the hooking portion 53 of the hook 50
and the handle 30, respectively.
[0034] In other embodiments, one of the locking tongues 34 of the
handle 30 may be omitted.
[0035] In other embodiments, the hook 50 may be unrotatably fixed
to the handle 30 and thereby omitting the third elastic member 40.
When the handle 30 needs to be closed, the handle 30 is rotated
towards the main body 30, and the guiding surface 560 of the
hooking block 56 of the hook 50 engages with the corresponding end
of the second connecting wall 24 of the main body 10, to guide the
