Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a mouse device; in
particular, to a mouse device having a suspended type switch
module.
2. Description of Related Art
[0002] The operating feeling (clicking sensation) generated by a
mouse depends on the distance between a trigger of a key and a
trigger point of a micro-switch, that is, the stroke distance of
pressing.
[0003] For the conventional mouse, as shown in FIG. 1, its switch
module 2A has a circuit board 21A and a micro-switch 22A which is
welded onto the circuit board 21A. However, since the circuit board
21A is disposed onto the pillar 121A of the lower shell 12A of the
mouse, it is easy to cause various tolerances in production, such
as assembly tolerances, dimensional tolerances of the lower shell,
welding tolerances of the micro-switch, and the thickness
tolerances of the circuit board, making the distance D between the
trigger 31A of the key 3A and the trigger point 221A of the
micro-switch 22A not conforming to the originally designed distance
and cannot achieve a better and consistent operating feeling.
[0004] In this regard, the present invention provides a solution to
overcome the aforementioned drawbacks.
SUMMARY OF THE INVENTION
[0005] An object of the present invention is to provide a mouse
device that can achieve a better and consistent operating
feeling.
[0006] In one aspect/configuration of a mouse device according to
the present disclosure, the mouse device is comprised of a mouse
shell, a switch module, and a key module. The mouse shell has an
upper shell and a lower shell, and the upper shell and the lower
shell are joined together to form a chamber. The switch module is
disposed within the chamber and is suspended from an inner side of
the upper shell. The key module is disposed on an outer side of the
upper shell. The key module is vertically movable and has a
trigger. The trigger enters the chamber through the upper shell to
activate the switch module when the key module is clicked.
[0007] Therefore, by locating the switch module on the inner side
of the upper shell in a hanging manner, the mouse device provided
by the present invention not only minimizes the impact of the
tolerance on the distance between the key module and the switch
module, but also enables the users to more readily adjust the
distance between the key module and the switch module.
[0008] In order to further the understanding regarding the present
invention, the following embodiments are provided along with
illustrations to facilitate the disclosure of the present
invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] The aforementioned illustrations and following detailed
descriptions are exemplary for the purpose of further explaining
the scope of the present invention. Other objectives and advantages
related to the present invention will be illustrated in the
subsequent descriptions and appended drawings.
First Embodiment
[0016] Refer to FIG. 2. The mouse device provided by the present
invention is comprised of a mouse shell 1, a switch module 2, and a
key module 3.
[0017] The mouse shell 1 has an upper shell 11 and a lower shell
12. The upper shell 11 and the lower shell 12 are joined together
to form a chamber 13. The switch module 2 is disposed within the
chamber 13 and is suspended from the inner side of the upper shell
11. The key module 3 is disposed on an outer side of the upper
shell 11. The key module 3 is vertically movable and has a trigger
31. The trigger 31 enters the chamber 13 through the upper shell 11
to activate the switch module 2 when the key module 3 is
clicked.
[0018] During the assembly, by suspending the switch module 2 onto
the inner side of upper shell 11, the influence of the tolerance
(such as the dimensional tolerances of the lower shell and the
thickness tolerance of the circuit board) on the distance d between
the trigger 31 of the key module 3 and the switch module 2 can be
eliminated to release the inconsistent operating feeling caused by
tolerances. In addition, before the lower shell 12 is assembled
onto the upper shell 11, the distance d between the trigger 31 of
the key module 3 and the switch module 2 can be easily
adjusted.
[0019] Conventionally, the key module 3 has a left key and a right
key, and the number of the switch module 2 can be two in
correspondence therewith. However, the present invention does not
intend to limit the number of the key module 3 and switch module 2.
It is worth noting that the mouse device provided by the present
invention further includes other components such as a scroll wheel,
an optical module and other elements for controlling the mouse
device, which are not further detailed herein. Hereinafter, the
features of the present invention will be described in more
detail.
[0020] In particular, on the inner side of the upper shell 11 there
is a protruding and downward-extending hanging pillar 111, and the
switch module 2 has a circuit board 21 and a micro-switch 22
disposed thereon. The position of the trigger point 221 of the
micro-switch 22 corresponds to that of trigger 31, so when the key
module 3 is pressed, the trigger 31 can press the trigger point 221
to trigger the micro-switch 22 to generate a trigger signal. In
addition, the circuit board 21 can be connected to the hanging
pillar 111 through an adjusting screw 4.
[0021] In this embodiment, the number of the hanging pillar 111 is
two, and so is the number of the adjusting screw 4. Namely, the
hanging pillars amount to two in parallel, and the adjusting screws
amount to two in parallel as well. The two adjusting screws 4 are
respectively screwed to the two hanging pillars 111 through the
circuit board 21 from below going upward. The two hanging pillars
111 are spaced apart from each other, and the micro-switch 22 is
located between the two hanging pillars 111.
[0022] It is noted that the number of hanging pillars 111 is not
limited to the quantities disclosed in the drawings, and their
positions are also not limited to the positions disclosed in the
drawings. They should be designed in accordance with actual needs
and arranged on the proper positions on the inner side of the upper
shell 11.
[0023] Furthermore, at the bottom potion of the hanging pillar 111,
there is a cavity with a screw hole 1111. The adjusting screw 4 has
a head portion 41 and a threaded rod portion 42 integrally
connected thereto. The threaded rod portion 42 of the adjusting
screw 4 can pass through the bottom and top surfaces of circuit
board 21 from below going upward for feeding the threaded rod
portion 42 into the screw hole 1111 such that the head portion 41
of the adjusting screw 4 abuts against the bottom surface of the
circuit board 21, and the circuit board 21 is located between the
head portion 41 of the adjusting screw 4 and the bottom portion of
hanging pillar 111. Because the micro-switch 22 is disposed on the
top surface of the circuit board 21 and the hanging pillar 111 is
connected to the top surface of the circuit board 21, the thickness
of the circuit board 21 will not affect the distance d between the
trigger 31 of the key module 3 and the trigger point 221 of the
micro-switch 22, and the mass-produced mice can achieve a
consistent operating feeling more readily.
Second Embodiment
[0024] Refer to FIG. 3 and FIG. 4 for the second embodiment of the
present invention. The difference between the first and the second
embodiments is that there is an orifice 121 at the lower shell 12,
and the position of the orifice 121 corresponds to that of the
adjusting screw 4. In this embodiment, the number of orifice 121 is
two, and the positions of the two orifices 121 correspond to that
of the two adjusting screws 4, respectively. With this, the user
can use a screwdriver to rotate the adjusting screw 4 through the
orifice 121 from the bottom of the mouse device, so the relative
distance between the circuit board 4 and the hanging pillar 111 is
changed along the long axis direction of the adjusting screw 4,
thereby adjusting the distance between the trigger 31 of the key
module 3 and the trigger point 221 of micro-switch 22. As shown in
FIG. 3, the trigger 31 of the key module 3 can abut against the
trigger point 221 of the micro-switch 22 directly by rotating the
two adjusting screws 4 clockwise, making the distance between the
trigger 31 of the key module 3 and the trigger point 221 of
micro-switch 22 become zero and thereby enabling the key module 3
to apply a preload force against the micro-switch 22, so that the
mouse device can provide the user with a preloaded operating
feeling. As shown in FIG. 4, the distance between the trigger 31 of
the key module 3 and the trigger point 221 of micro-switch 22 can
be increased by rotating the two adjust screws 4 counterclockwise,
thereby increasing the stroke distance of pressing, so that the
mouse device can provide the user with the operating feeling of
idle motion.
Third Embodiment
[0025] Refer to FIG. 5 and FIG. 6 for the third embodiment of the
present invention. The difference between the second and the third
embodiments is that the key module 3 has an orifice 32, and the
upper shell 11 has a through hole 1112 used for screwing the
adjusting screw 4 into the hanging pillar 111. In this embodiment,
the number of orifice 32 is two, the number of the through hole
1112 is two as well, and the positions of the two orifices 32
correspond to that of the two through holes 1112, respectively.
With this, the user can use a screwdriver to rotate the adjusting
screw 4 through the orifice 32 and the through hole 1112 from the
top of the mouse device, so the relative distance between the
circuit board 4 and the hanging pillar 111 is changed along the
long axis direction of the adjusting screw 4, thereby adjusting the
distance between the trigger 31 of the key module 3 and the trigger
point 221 of micro-switch 22. As shown in FIG. 5, the trigger 31 of
the key module 3 can abut against the trigger point 221 of the
micro-switch 22 directly by rotating the two adjusting screws 4
clockwise, making the distance between the trigger 31 of the key
module 3 and the trigger point 221 of micro-switch 22 become zero
and thereby enabling the key module 3 to apply a preload force
against the micro-switch 22, so that the mouse device can provide
the user with a preloaded operating feeling. As shown in FIG. 6,
the distance between the trigger 31 of the key module 3 and the
trigger point 221 of micro-switch 22 can be increased by rotating
the two adjusting screws 4 counterclockwise, thereby increasing the
stroke distance of pressing, so that the mouse device can provide
the user with the operating feeling of idle motion.
[0026] In summary, by locating the switch module on the inner side
of the upper shell in a hanging manner, the mouse device provided
by the present invention not only minimizes the impact of the
tolerance on the distance between the key module and the switch
module, but also enables the users to adjust the distance between
the key module and the switch module, so as to satisfy user
needs.
[0027] The descriptions illustrated supra set forth simply the
preferred embodiments of the present invention; however, the
characteristics of the present invention are by no means restricted
thereto. All changes, alterations, or modifications conveniently
considered by those skilled in the art are deemed to be encompassed
within the scope of the present invention delineated by the
following claims.
