Description

Technical Field

[0001] This utility model relates to the field of keyboard key technology, and in particular to an installation structure for a pressing device of a magnetic axis keyboard key switch. Background Technology

[0002] The existing patent for Hall element magnetic shaft keyboard key switch, patent number 2024223061297, discloses the installation structure of the pressing device in the Hall element magnetic shaft keyboard switch. In this structure, the guide groove on the pressing device cooperates with the sliding rib on the base to form a sliding guide; the locking part of the pressing device cooperates with the first opening of the upper cover, and the upper cover and the base are fixed by a snap-fit ​​connection. The pressing device, the upper cover and the base cooperate with each other, and the installation tolerance is relatively large. Utility Model Content

[0003] To address the shortcomings in the prior art, this utility model provides an installation structure for the pressing device of a magnetic shaft keyboard key switch.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an installation structure for a pressing device of a push button switch, including an upper cover, a pressing element and a base, an elastic element is provided between the pressing element and the base, a guide groove and a guide strip form a longitudinal guiding connection between the pressing element and the upper cover to provide guidance for pressing the pressing element, and the upper cover and the base are snap-fit ​​connected.

[0005] The pressing component includes a body, a pressing part, and a guide bar, with the guide bar placed on the side wall of the body.

[0006] The top cover has a through hole, and the side wall of the through hole has a guide groove, and the guide bar cooperates with the guide groove.

[0007] The guide bar has a groove.

[0008] Both the guide groove sidewall and the through hole sidewall are provided with longitudinal ribs. The end of the rib facing the base is set at an angle.

[0009] The main body is cylindrical, and the pressing part is located at the upper end of the main body.

[0010] The upper end face of the main body is provided with a receiving cavity, and the pressing part is placed in the receiving cavity.

[0011] The base has a locking protrusion, and the top cover has a locking hole, with the locking protrusion and the locking hole being adapted to each other.

[0012] The above technical solution effectively improves the problem of large installation tolerances in the pressing mechanism of existing magnetic shaft keyboard key switches. The longitudinally guided pressing component achieves this by simply mating with the top cover, reducing tolerances, improving the user experience (feel), and simplifying the assembly process.

[0014] Figure 2 This is a schematic diagram of the disassembled state of this utility model.

[0015] Figure 3 This is a schematic diagram of the upper cover. Detailed Implementation

[0016] refer to Figure 1-3 As can be seen, this utility model discloses an installation structure for a pressing device of a push button switch, including an upper cover 1, a pressing member 2 and a base 3. An elastic member (not shown in the figure) is provided between the pressing member 2 and the base 3. The guide groove 12 and the guide strip 23 between the pressing member 2 and the upper cover 1 form a longitudinal guiding connection to provide guidance for the pressing of the pressing member 2. The upper cover 1 and the base 3 are snap-fit ​​connected.

[0017] The pressing component 2 includes a body 21, a pressing part 22, and a guide strip 23. The guide strip 23 is placed on the side wall of the body 21, as shown in the attached figure. Figure 2 As shown, the guide bar 23 is provided with a groove 231, which provides space for the guide bar 23 to deform, in conjunction with the attached... Figure 3 As shown, the ribs 121 on the inner wall of the guide groove 12 make the guide strip 23 and the guide groove 12 fit tightly, enhancing the user experience of the button.

[0018] The upper cover 1 has a through hole 11, and the side wall of the through hole 11 has a guide groove 12. The guide groove 12 extends toward the base 3. The guide strip 23 cooperates with the guide groove 12 and slides along the guide groove 12, as shown in the attached figure. Figure 3 As shown, the top of the guide groove 12 is sealed to limit the stroke of the pressing member 2.

[0019] Both the sidewall of the guide groove 12 and the sidewall of the through hole 11 are provided with longitudinal ribs 121. The end of the rib 121 facing the base 3 is set with an inclined surface 122, as shown in the attached figure. Figure 3 As shown, this facilitates the insertion of the guide bar 23 into the guide groove 12.

[0020] The main body 21 is cylindrical, and a receiving cavity 211 is provided on the upper end surface of the main body 21. The pressing part 22 is placed in the receiving cavity 211 and is located at the upper end of the main body 21, as shown in the attached figure. Figure 1-2 As shown, the body 21 is inserted into the through hole 11, and the inner wall of the through hole 11 is provided with ribs 121. The sufficiently long body 21 is tightly connected to the through hole 11 to enhance stability.

[0021] The base 3 has a latching protrusion 31, and the upper cover 1 has a latching hole 13. The latching protrusion 31 is adapted to the latching hole 13, and in conjunction with the attached... Figure 2As shown, the base 3 and the top cover 1 are connected by a snap-fit.

[0022] Specifically, in conjunction with the appendix Figure 2-3 As shown, the pressing component 2 is inserted into the through hole 11 from the bottom of the upper cover 1. At the same time, the guide strip 23 slides in along the guide groove 12. An elastic element (not shown in the figure) is provided between the pressing component 2 and the base 3. The upper cover 1 and the base 3 are connected by a snap-fit ​​connection between the snap protrusion 31 and the snap hole 13. The pressing component 2 only has the upper cover 1 as its mating part, and the other component, the base 3, does not need to be considered, which reduces the tolerance during assembly, improves product stability, and enhances the user experience.

[0023] This invention effectively improves the problem of large installation tolerances in the pressing device of existing magnetic shaft keyboard key switches. By using a longitudinally guided pressing component 2 that only needs to cooperate with the upper cover 1, tolerances are reduced, the user experience (feel) is improved, and the assembly process is relatively simple.

[0024] Obviously, the above embodiments are merely illustrative examples for clarity and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
