Description

Technical Field

[0001] This utility model relates to the field of mouse technology, and in particular to a low-noise mouse button structure and a low-noise mouse. Background Technology

[0002] When pressing a mouse, noise is generally generated in two stages. The first stage is when the button presses the switch to move down or deform, and the second stage is when the switch moves up to reset or returns to its original shape and touches the button, producing a sound. Currently, most methods reduce noise by setting a silencing component between the button and the switch. However, this requires placing the silencing component on the button's travel path, which will more or less affect the mouse's pressing feel. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a low-noise mouse button structure and a low-noise mouse. The bottom of the mouse button has a relief part and a noise-reducing part on both sides of the switch contact. A first arc surface is provided on the relief part, and a second arc surface is provided on the contact surface. When the mouse button is pressed, the impact force between the mouse button and the switch can be reduced to reduce the pressing collision noise. When the mouse button is released, the impact force between the contact and the pressing post when the contact returns to its original position can be reduced to reduce the rebound collision noise, thereby achieving the purpose of reducing the mouse button pressing noise.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] The low-noise mouse button structure features a cantilever button with its positioning end detachably fixed to the inner wall of the mouse's upper shell, and its free end extending to the front of the mouse. A switch is located below the free end, situated on a circuit board within the mouse, and its upper end has a protruding contact.

[0006] The inner wall of the free end is provided with a pressing post extending toward the switch, and its lower end extends above the contact. The bottom end of the pressing post forms a clearance part and a noise-mute part on two opposite sides of the contact. The clearance part extends toward the front end of the mouse and extends to the side wall of the pressing post. The noise-mute part extends obliquely upward toward the rear end of the mouse and extends to the side wall of the pressing post.

[0007] The sidewall of the clearance part is a first arc surface and is smoothly connected to the bottom end of the pressing column;

[0008] A sound-absorbing cotton is fitted into the positioning part, and the bottom end of the sound-absorbing cotton extends to the outside of the pressing column.

[0009] Another technical solution adopted by this utility model is as follows:

[0010] A low-noise mouse, wherein the mouse has two or more mouse buttons, and each mouse button has the low-noise mouse button structure described in the previous technical solution.

[0011] As a further explanation of the above technical solution:

[0012] In the above technical solution, the upper surface of the contact point is a smooth second arc surface.

[0013] In the above technical solution, a first sliding groove extending in the same direction as the pressing post is formed on the side wall facing the positioning end of the pressing post. The first sliding groove is located above the noise-absorbing part, and a first protrusion adapted to the first sliding groove is formed on the inner wall of the mouse upper shell.

[0014] In the above technical solution, one or more guide posts extending toward the bottom shell of the mouse are formed on the inner wall of the free end of each mouse button, and a second slide groove extending in the same direction as the first slide groove is formed on each guide post. A plurality of second protrusions that are adapted to the second slide grooves are formed on the inner wall of the upper shell of the mouse.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a relief part and a noise reduction part on both sides of the bottom end of the pressing post on the mouse button, and setting a first arc surface on the relief part and a second arc surface on the contact surface, the impact force between the mouse button and the switch can be reduced when the mouse button is pressed to reduce the pressing collision noise, and the impact force between the contact and the pressing post when the mouse button is released can be reduced to reduce the rebound collision noise, thereby achieving the purpose of reducing the mouse button pressing noise.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of a second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] like Figure 1-2 As shown, the low-noise mouse button structure has a cantilever structure. Its positioning end 11 is detachably fixed to the inner wall of the mouse upper shell 20, and its free end 12 extends to the front end of the mouse. A switch 30 is provided below the free end 12. The switch 30 is located on a circuit board inside the mouse, and its upper end is provided with a protruding contact 1.

[0025] like Figure 2-3 As shown, a pressing post 2 extending toward the switch 30 is provided on the inner wall of the free end 12, and its lower end extends above the contact 1. The bottom end of the pressing post 2 forms a clearance portion 4 and a noise-absorbing portion 3 on opposite sides of the contact. The clearance portion 4 extends toward the front end of the mouse and onto the side wall of the pressing post 2, and the noise-absorbing portion 3 extends obliquely upward toward the rear end of the mouse and onto the side wall of the pressing post 2. The clearance portion 4 is located above one side of the contact 1, and its side wall is a first arc surface 5 that smoothly connects to the bottom end of the pressing post 2. The positioning portion 3 is located above the other side of the contact 1, and a noise-absorbing cotton 40 is fitted thereon. The bottom end of the noise-absorbing cotton 40 extends to the outside of the pressing post 2.

[0026] When the mouse button 10 is pressed, the arc surface 5 at the bottom of the pressing post 2 first contacts the contact point 1 and pushes it to deform or move downward. The avoidance part 4 can reduce the impact force between the two and reduce the sound of the pressing collision. At the same time, the avoidance part 4 can avoid the switch 30 to avoid contact with the pressing post 2 and make a sound. When the mouse button 10 is released, the pressing post 2 moves upward and leaves the contact point 1 and returns to its original position. The contact point 1 slides from the arc surface 5 to the bottom of the pressing post 2 and hits the sound-absorbing cotton 40, which can reduce the sound of the rebound collision.

[0027] Figure 1-5 A specific application embodiment of the above embodiments is shown: a low-noise mouse with two or more mouse buttons 10, each mouse button 10 having the low-noise mouse button structure of the above embodiments.

[0028] like Figure 2 As shown, the upper surface of contact 1 is a smooth second arc surface 9.

[0029] It is understandable that the second arc surface 9 on the contact point 1 cooperates with the first arc surface 5 of the avoidance part 4 to better decompose and reduce the impact force between the pressing column 2 and the switch 30, thereby reducing the collision noise.

[0030] like Figure 4-5As shown, a first groove 6 extending in the same direction as the pressing post 2 is formed on the side wall facing the positioning end 11 of the pressing post 2. The first groove 6 is located above the noise-reducing part 3. A first protrusion 21 adapted to the first groove 6 is formed on the inner wall of the mouse upper shell 20. One or more guide posts 7 extending towards the mouse bottom shell 50 are also formed on the inner wall of the free end 12 of each mouse button 10. A second groove 8 extending in the same direction as the first groove 6 is formed on each guide post 7. A number of second protrusions 22 adapted to the second grooves 8 are formed on the inner wall of the mouse upper shell 20.

[0031] It is understandable that the first protrusion 21 and the second protrusion 22 cooperate with the first slide groove 6 and the second slide groove 8 respectively, which can better guide the downward movement direction of the free end 12, and limit the maximum relative displacement between the mouse button 10 and the mouse upper shell 20 through their structure and shape, ensuring that the pressing column 2 and the contact point 1 are always within a safe relative displacement range.

[0032] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the technical scope of this utility model.
