Description

Mouse device

Technical Field

The present invention relates to input devices, and particularly to a mouse device.

Background

The mouse is used for controlling a cursor on a computer screen and operating the computer accordingly. Since 1968 the first mouse made in the united states, the mouse has become an integral part of computer equipment, whether it be for paperwork, video games, industrial graphics, design graphics, or media production. In the early mouse, a trackball is used as the displacement detection of the mouse, and along with the improvement of science and technology and the improvement of the working efficiency of the mouse, the displacement detection mode using an optical or laser sensing module is slowly developed. In addition, in order to improve the functionality and convenience of the mouse, the mouse has evolved from the earliest wired single-key mouse to the wireless multi-key roller mouse. According to different industrial requirements or personal preferences, various home appliance manufacturers also start to manufacture various mice with different shapes or complex functions to meet the operation requirements of different users.

The pressing element 902 can pass through the key opening 921 of the upper base 92 and is disposed above the trigger 702, so that when the user presses the key 901, the pressing element 902 presses the trigger 702, and the switch module 70 outputs a corresponding control signal. However, since a gap G exists between the pressing member 902 and the triggering portion 702, the button 902 may generate an idle stroke when being pressed down, so that the switch module 70 may not output a corresponding control signal in time, and a user may feel bad pressing feeling.

Therefore, how to provide a mouse device capable of avoiding the generation of a pressing idle stroke is the technical subject to be solved by the invention.

Detailed Description

The advantages and features of the present invention and methods of accomplishing the same will be understood more readily by reference to the following detailed description of exemplary embodiments and the accompanying drawings. This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

First, please refer to fig. 2 and 3, fig. 2 is an exploded perspective view of a mouse device according to the present invention; fig. 3 is an exploded perspective view of another perspective of the mouse device provided by the present invention. The mouse device 1 includes: the key assembly comprises a key 10, an upper cover 20, an elastic element 40, a lower cover 50, a switch module 70 and a circuit board 80. The upper cover 20 may be combined with the lower cover 50 to form an inner receiving space of the mouse device 1. The elastic element 40 is a compression spring, and the circuit board 80 is located in the inner accommodating space and disposed on the lower cover 50. The switch module 70 is disposed on the circuit board 80, and the switch module 70 also has a switch element 701 and a trigger portion 702 disposed on the switch element 701.

The key 10 includes a pressing portion 12 and a bending connection portion 11 connected to the pressing portion 12. A pressing member 121 is disposed on one surface of the pressing portion 12, and a disposition position of the pressing member 121 corresponds to a disposition position of the triggering portion 702 of the switch module 70. And the bent connection portion 11 has two opposite pivot holes 111. In the present embodiment, the pressing member 121 has a pressing portion 1211 and a receiving groove 1212, the pressing portion 1211 is used for abutting against the triggering portion 702 of the closing module 70; the receiving groove 1212 is used for receiving the elastic element 40, so as to position the elastic element 40.

The outer surface of the upper cover 20 has a groove 201 corresponding to the shape of the pressing portion 12, and the inner surface of the upper cover 20 extends with a support 202. The bottom surface of the recess 201 has an opening 2011 and a relief opening 2012 at the control end. In this embodiment, the position of the offset opening 2012 corresponds to the position of the pressing element 121, so that the pressing element 121 can be inserted into the offset opening 2012 and abut against the triggering portion 702 of the closing module 70. In addition, a limiting shaft 2013 extends from the closed end of the offset opening 2012, the limiting shaft 2013 is configured to penetrate through the elastic element 40 to position the elastic element 40 in the accommodating groove 1212, and two ends of the elastic element 40 respectively abut against the pressing portion 1211 of the pressing member 121 and the inner surface of the upper cover 20.

The bending connection portion 11 is disposed through the opening 2011 and can be pivotally connected to the support member 202. In this embodiment, the supporting element 202 has a slot 2021, and a shaft 30 passes through the pivot hole 111 and the slot 2021, so that the key 10 can be pivotally connected to the upper cover 20 through the bending connection portion 11 and the supporting element 202, so that the key 10 can swing relative to the upper cover 20.

Referring to fig. 4A, fig. 4A is a cross-sectional view of a mouse device provided by the present invention; fig. 4B is an enlarged view of the area a in fig. 4A. In fig. 4A, the upper cover 20 is combined with the lower cover 50, and the bending connection portion 11 is disposed through the opening 2011 of the upper cover 20 and pivotally connected to the supporting member 202. The pressing element 121 is disposed through the relief opening 2012 and abuts against the triggering portion 702 of the closing module 70.

In fig. 4B, the elastic element 40 is disposed in the receiving groove 2012, and the limiting shaft 2013 penetrates through the elastic element 40 to position the elastic element 40, so that the elastic element 40 can be maintained between the pressing portion 1211 and the upper cover 20. Since the two ends of the elastic element 40 respectively abut against the pressing portion 1211 and the inner surface of the upper cover 20, the elastic element 40 can provide a spring force F to the pressing portion 1211, so that the pressing portion 1211 can tightly abut against the triggering portion 702 of the switch module 70 without triggering the switch module 70. In this embodiment, the spring force F provided by the elastic element 40 is not greater than 10 g. It should be further noted that although the present invention only proposes the embodiment in which the elastic element 40 is a compression spring, in practical applications, it can be replaced by other elastic materials, such as: elastic rubber, elastic silica gel or elastic sheets. On the other hand, although the limiting shaft 2013 is disposed at the closed end of the receding opening 2012 (as shown in fig. 2 or fig. 3), in practical applications, the limiting shaft 2013 may be disposed on the other surface of the pressing portion 1211 opposite to the switch module 70, or the limiting shaft 2013 may not be disposed, and the elastic element 40 is only accommodated and positioned by the accommodating groove 1212, so the embodiment of the present invention is not limited thereto.

Referring to fig. 4B, since the pressing portion 1211 is attached to the triggering portion 702 of the switch module 70, no gap is generated between the pressing portion 1211 and the triggering portion 702, when the user presses the pressing portion 12 of the key 10, the pressing portion 1211 can immediately press the triggering portion 702, so that the pressing feeling of idle stroke is not generated, and the switch module 70 can be triggered accurately and instantly to generate the control signal. In addition, when the user presses the key 10, the elastic element 40 is also elastically extended, so that the force of the user pressing the key 10 is reduced, and the user has a good pressing feeling.

The mouse device provided by the invention can avoid the generation of pressing time-space travel by the arrangement of the elastic element, so that the switch module of the mouse device can respond to the pressing action of a user in real time and output a corresponding control signal. On the other hand, when a user presses the key, the elastic extension of the elastic element can also reduce the pressing force of the user, so that the user can generate good pressing hand feeling; therefore, the present invention is an invention with great industrial value.

The invention may be modified in various ways by anyone skilled in the art without however departing from the scope of the appended claims.
