Description

Technical Field

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

[0002] Currently, most mouse button pre-press structures on the market use torsion ring technology to achieve the pre-press function. This type of design has obvious drawbacks: First, the circuit design of torsion rings or traditional springs makes it easy for the springs to hook together during packaging, requiring additional hook separation springs during production line assembly, which greatly increases the complexity of installation. Second, in the existing structure, when the button rebounds, the wear-resistant plate directly impacts the anti-pull groove of the plastic frame, producing harsh noise and a poor tactile experience. In addition, conventional mouse buttons only directly contact the micro switch contacts through the wear-resistant plate, lacking an effective buffer structure, resulting in large contact impact buffering and a harsh button feel. Utility Model Content

[0003] The purpose of this utility model is to provide a mouse button pre-compression structure to solve the problems of complex installation, high production cost, harsh noise when the button rebounds, and poor tactile experience of common mouse button pre-compression structures.

[0004] This utility model achieves the above-mentioned objectives through the following technical solution: it includes a mouse body, a main control board, a button assembly, a micro switch, and a battery. The button assembly is mounted on the mouse body, and a frame-type abutting structure is provided at the bottom of the button assembly. The main control board and the micro switch are both installed inside the mouse body and electrically connected to the battery. A button post is provided between the abutting structure and the micro switch. A plastic frame is also installed inside the mouse body. A pair of reverse pull arms are provided at the front end of the plastic frame. A steel wire retainer is installed on the inner side of the reverse pull arms, and the end of the retainer extends into the abutting structure and connects with it.

[0005] Furthermore, the two pull arms abut against the top of the micro switch via plastic sheets at the bottom, the front end of the pull arms extends into the hollow part of the abutment structure frame, and one end of the retaining ring is installed in the retaining ring groove on the pull arm.

[0006] Furthermore, the retaining ring includes a central shaft and hooks at both ends thereon. The planes extending from the axes of the two hooks are perpendicular to each other. The hook located inside the abutment structure has its opening facing upward, and the bottom of the hook is connected to the top of the bottom plate of the abutment structure.

[0007] Furthermore, the button post includes a silicone sleeve, the bottom of which is embedded with a wear-resistant sheet, the bottom of which is in contact with the contact of the micro switch, and the top of which is mounted on the bottom of the abutment structure.

[0008] Furthermore, the main control board, the button assembly, the micro switch, and the plastic frame are all installed inside the mouse body using screws.

[0009] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:

[0010] 1. In this utility model, the preload of the wire snap ring acts on the button assembly through the counter-pull arm, balancing the tension generated by the spring arm at the button end, so that the downward pressure is consistent with the switch feedback force. When the spring rebounds, the snap ring restricts the rebound of the button post, avoiding impact on the frame and improving the sound and feel.

[0011] 2. In this utility model, the silicone sleeve of the button post is wrapped with a wear-resistant sheet. When the micro switch contact is made, the edge of the silicone sleeve contacts the wear-resistant sheet first, which effectively reduces the cushioning and improves the button feel.

[0012] 3. In this utility model, the hooks of the snap ring intersect perpendicularly and have no loop design, which avoids the springs getting hooked during production and assembly. It can be installed in both left and right directions, reducing the difficulty of installation. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Combination Figures 1 to 5The mouse button pre-press structure shown includes a mouse body 1, a main control board, a button assembly 2, a micro switch 3, and a battery. The button assembly 2 is mounted on the mouse body 1. The bottom of the button assembly 2 is provided with a frame-type abutting structure 201. The main control board and the micro switch 3 are both installed inside the mouse body 1 and electrically connected to the battery. A button post 4 is provided between the abutting structure 201 and the micro switch 3. A plastic frame 5 is also installed inside the mouse body 1. A pair of reverse pull arms 501 are provided at the front end of the plastic frame 5. A steel wire retainer 6 is installed on the inner side of the reverse pull arms 501. The end of the retainer 6 extends into the abutting structure 201 and is connected.

[0022] Among them, the two pull arms 501 abut against the top of the micro switch 3 through the plastic sheet at the bottom, and the front arm of the pull arm 501 extends to the hollow part inside the frame of the abutment structure 201. One end of the snap ring 6 is installed in the snap ring groove 502 on the pull arm 501.

[0023] The snap ring 6 includes a central shaft 601 and hooks 602 at both ends. The extended planes containing the axes of the two hooks 602 are perpendicular to each other. The hook 602 located inside the abutment structure 201 has its opening facing upward, and the bottom of the hook 602 is connected to the top of the bottom plate of the abutment structure 201.

[0024] The button post 4 includes a silicone sleeve 401, with a wear-resistant plate 402 embedded at the bottom of the silicone sleeve 401. The bottom of the wear-resistant plate 402 is in contact with the contact of the micro switch 3, and the top of the silicone sleeve 401 is mounted on the bottom of the abutment structure 201.

[0025] The main control board, button assembly 2, micro switch 3, and plastic frame 5 are all installed inside the mouse body 1 with screws.

[0026] Working principle: When the button assembly 2 is pressed, the abutment structure 201 moves the button post 4 downward. The wear-resistant piece 402 at the bottom of the button post 4 contacts the contact of the micro switch 3. Because the silicone sleeve 401 covers the wear-resistant piece 402, when the contact of the micro switch 3 is pressed all the way down, the silicone sleeve 401 contacts the housing of the micro switch 3 before the wear-resistant piece 402, preventing the wear-resistant piece 402 from hitting the housing of the micro switch 3 first and causing an impact sound, thus reducing the cushioning of the micro switch 3. The steel wire retaining ring 6 installed inside the anti-pull arm 501 at the front end of the plastic frame 5 extends into... The abutting structure 201 is connected to the button assembly 2. The preload of the retaining spring 6 is applied to the button assembly 2 through the counter-pull arm 501 to balance the tension generated by the spring arm at the button end, so that the downward pressure is consistent with the feedback force of the switch. When the button rebounds, the retaining spring 6 restricts the rebound of the button post 4, preventing it from directly impacting the counter-pull arm 501 of the plastic frame 5 while being wrapped by the abutting structure 201, thereby improving the sound and feel. The hooks 602 at both ends of the central shaft 601 of the retaining spring 6 intersect perpendicularly. The hooks 602 located in the abutting structure 201 have their openings facing upwards and are connected to the top of the base plate. This foolproof design without loops can reduce the difficulty of production and assembly.
