[0004] Following to the advancement and popularity of computer
technology, computers have entered into our daily life. The great
development of computer industry has resulted in types of functions
of computer, furthermore, along with broad application of
computers, a lot of data such as personnel photo, bank accounts,
password or database, R&D data and commercial secrets of
company are stored in the hard drive of the computers. In case of
the computer is attacked by virus and damaged by people, data
stored in the computer would be destroyed, thus, the data saved in
the computer have to backup.
[0005] However, due to large quantity of data and small capacity of
the portable USB disk, so that it is impossible to backup data
saved in the hard drive. Although the built-in hard drive has
enough capacity to backup the data, however, it is difficult to
disassemble quickly and is also inconvenient to carry with after
disassembly, thus, some manufacturers developed the mobile hard
drive.
[0006] Referring to FIG. 9, a chamber A1 is made in an external
shell A, and a open A11 is set at one side of the chamber A1.
Meanwhile, a mobile device B can be mounted in the chamber A1. The

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0020] Referring to FIGS. 1, 2, 3, 4 and 7, a lockup structure of
mobile hard drive of the present invention is shown comprised of a
base plate 1, a base frame 2, a lock member 3, a spiral arm 4 and a
hard drive 5.
[0021] The base plate 1 has a chamber 10 for receiving the hard
drive 5, and a groove 11 is made in front of the base plate 1.
[0022] The base frame 2 comprises a through hole 21 at one side for
mounting the lock member 3, a sectional slot 22 at another side,
and a concave portion 23 between the through hole 21 and the
sectional slot 22. The through hole 21 has a position slot 211 at
the back side thereof. The sectional slot 22 inside has an axial
portion 221 which is used for pivoting the spiral arm 4, and a
limiting spring arm 222 at the rear side of the axial portion 221.
The concave portion 23 has a through slot 231 at one lateral side,
and a buckle 232 is suspended in the through slot 231 at one
side.
[0023] The lock member 3 has a lock head 31 for inserting a preset
key, a block sheet 33 fixed at rear side of the lock head 31, and
two position elements 32 between the lock head 31 and the block
sheet 33. The lock head 31 comprises a lock axis 311 that can
rotate with the preset key inserted into the lock head 31.
[0024] The spiral arm 4 has a handle 41 at the free end for
grasping by a user, which comprises a protruding block 42, a notch
421 and a buckling groove 422 at one side, and a position block 43
at the fixed end. The position block 43 comprises a limiting block
431 extended from one side.
[0025] The hard drive 5 is one set of hard driver with different
types, sizes or specifications.
[0026] During installation, the base frame 2 is fixed in the groove
11 of the base plate 1, and the lock member 3 is mounted in the
through hole 21 of the base plate 2 enable the lock head 31 of the
lock member 3 protruded out of the through hole 21. Then, the
position element 32 of the lock member 3 is inserted into the
position slot 211 of the through hole 21 for positioning.
Meanwhile, the spiral arm 4 is pivoted with the axial portion 221
inside the sectional slot 22 of the base frame 2, so that the
spiral arm 4 can turn between the locking position that the
protruding block 42 is received into the concave portion 23, and
the unlocking position. Finally, the hard drive 5 is mounted in the
chamber 10 of the base plate 1.
[0027] Referring to FIGS. 2, 4, 5, 6, 7 and 8, after insertion of
the hard drive 5 into the chamber 10 of the base plate 1, turn the
handle 41 of the spiral arm 4 to force the protruding block 42 into
engagement with the through slot 231 of the concave portion 23
(i.e., turn the spiral arm 4 from the unlocking position to the
locking position). At this time, the present key is inserted into
the lock head 31 of the lock member 3 within the through hole 21 to
turn the block sheet 33 at rear side of the lock axis 311
counter-clockwise so that the block sheet 33 is buckled into the
notch 421 of the protruding block 42, thereby securing the spiral
arm 4 positively in the sectional slot 22 of the base frame 2.
[0028] When turning the lock head 3 with the lock axis 311 of the
lock member 3 in the reversed direction from the locking position
to the unlocking position, the block sheet 33 is turned clockwise
to disengage from the notch 421 of the spiral arm 4. Thus, the user
can directly open the spiral arm 4 by a hand.
[0029] In addition, the spiral arm 4 will not disengage from the
base frame 2 by an external force as the block sheet 33 of the lock
member 3 is buckled into the notch 421 of the spiral arm 4.
Meanwhile, the position block 43 of the spiral arm 4 is also fixed
in a fixing slot 61 of a shell 6. Thus, the base plate 1, the base
frame 2 and the hard drive 5 can be positioned in the shell 6, and
any wrong withdrawal will also be avoided accordingly.
[0030] Referring to FIGS. 2, 7 and 8, when mounting in the shell 6,
the position block 43 and the limiting block 431 are positioned at
the fixing end of the spiral arm 4, and if the user pushes the free
end of the spiral arm 4 outwardly, the limiting block 431 will be
pushed against the limiting spring arm 222 to force the limiting
spring arm 222 to produce elastic distortion. Furthermore, such
elastic distortion of the limiting spring arm 222 will be limited
as reaches a preset distance, so that the spiral arm 4 will not
rotate continuously, thus, the spiral arm 4 can be limited. At this
moment, the base plate 1 can be disengaged from the shell 6. On the
contrary, if the user stops pushing the free end of the spiral arm
4 outwardly, the elasticity of the limiting spring arm 222 can push
the limiting block 431 of the spiral arm 4 so as to let the spiral
arm 4 move toward the sectional slot 22 of the base frame 2.
[0031] The shell 6 can be a socket in the computer for receiving a
mobile hard drive or CD driver, and it is used to insert the hard
drive 5 to connect the computer for data transmission. Besides, the
fixing slot 61 of the shell 6 is used to position the position
block 43 of the spiral arm 4.
[0032] Furthermore, when the user pushes the spiral arm 4 to the
locking position, the protruding block 42 of the spiral arm 4 will
be moved into the concave portion 23 of the base frame 2 against
the buckle 232 in the concave portion 23 to produce elastic
displacement. As the spiral arm 4 continues to move against the
base frame 2 for positioning, the buckling groove 422 at one side
of the protruding block 42 is used to reset the buckle 232. Because
the buckle 232 of the base frame 2 is rest in the buckling groove
422 of the spiral arm 4, the free end of the spiral arm 4 can be
positioned in the concave portion 23 of the base frame 2
positively. Meanwhile, when the user inserts the preset key into
the lock member 3 to turn the lock head 31 with the block sheet 33
counter-clockwise, the block sheet 33 can be positioned in the
notch 421 of the spiral arm 4, and the user doesn't align it first
before operation.
[0033] The position block 43 and the limiting block 431 at the
fixing end of the spiral arm 4 can be fixed at the spiral arm 4
separately, or one-body molded with the spiral arm 4.
[0034] The lockup structure of mobile hard drive of the present
invention is practical, and its advantages are as follows.
[0035] 1. As the spiral arm 4 is in locking position, the position
block 43 can be positioned in the fixing slot 61 of the shell 6
that can prevent the hard drive 5 out off the shell 6, therefore,
the hard drive 5 can be positioned in the shell 6 properly.
[0036] 2. As the spiral arm 4 is in locking position and the
position block 43 is positioned in the fixing slot 61 of the shell
6, the user can insert the preset key into the lock head 31 of the
lock member 3 to turn the lock head 31 with the block sheet 33
counter-clockwise enable the block sheet 33 located into the notch
421 of the spiral arm 4. Even if the user withdraws the preset key
from the lock member 3, since the spiral arm 4 can not be pushed
outwardly, it is also impossible to disengage the hard drive 5 from
the shell 6, therefore, the hard drive 5 can be locked up and avoid
wrong withdrawal accordingly.
[0037] 3. As the spiral arm 4 is in locking position, the position
block 43 at the fixing end and the buckling groove 422 at free end
of the spiral arm 4 are against the limiting spring are 222 and the
buckle 232 respectively to prevent the spiral arm 4 from opening
due to slant, vibration or other unexpected situations. Besides,
the user doesn't need to confirm whether the block sheet 33 of the
lock member 3 is aimed at the notch 421 of the spiral arm 4, so,
operation of the present invention is very easy.
[0038] Therefore, the lockup structure of mobile hard drive of the
present invention comprises the base plate 1, the lock member 3 and
the spiral arm 4. The block sheet 33 of the lock member 3 can be
located in the notch 421 at the free end of the spiral arm 4, and
the position block 43 at the fixing end of the spiral arm 4 is
positioned in the fixing slot 61 of the shell 6, so that the hard
drive 5 installed in the base plate 1 will not be withdrawn or
stolen. However, above descriptions are only the preferred
embodiments of this invention, but not limited to the patent claims
of this invention, therefore, all simple decorations and structural
changes basing on instructions and drawings of this invention will
be included into the patent claims of this invention.
[0039] Although a particular embodiment of the invention has been
