[0006] The housing includes a mounting cavity disposed inside the housing, a micro switch fixedly mounted relative to the housing is disposed in the mounting cavity, and a through hole corresponding to the position of the micro switch is provided on the side wall of the housing.

[0007] The pressing cantilever is located inside the through hole and one end is connected to the housing. The free end of the pressing cantilever is movable inside the through hole.

[0008] A cover is disposed on the outer wall of part of the housing and covers the through hole. Pressing the cover actuates the free end of the pressing cantilever and triggers the micro switch.

[0009] Optionally, the pressing cantilever is integrally formed with the housing.

[0010] Optionally, the pressing cantilever protrudes from the wall of the through hole and is disposed in the through hole, and a U-shaped gap is formed between the wall of the through hole and the outer edge of the pressing cantilever.

[0011] Optionally, an elastic sealant is provided in the U-shaped gap, and the elastic sealant is integrally formed by a two-color injection molding process to connect the outer edge of the pressing cantilever and the wall of the through hole.

[0012] Optionally, the pressing arm has a first surface and a second surface disposed opposite to each other. The first surface protrudes outward from the pressing member toward the cover. The end of the pressing member contacts the inner surface of the cover. Pressing the pressing member can move the pressing arm and trigger the micro switch on the second surface.

[0013] Optionally, the first surface is further provided with a reinforcing rib extending along the extension direction of the pressing cantilever, the reinforcing rib extending from the pressing member to the connection between the pressing cantilever and the housing.

[0014] Optionally, the cover includes a connecting area located on the periphery and a deformable area surrounded by the connecting area.

[0029] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0031] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0032] According to a micro-controlled switch structure disclosed herein, such as Figures 1 to 4 As shown, it includes:

[0033] The housing 10 includes a mounting cavity 11 disposed inside the housing 10. A micro switch 12 is fixedly mounted relative to the housing 10 in the mounting cavity 11. A through hole 13 corresponding to the position of the micro switch 12 is provided on the side wall of the housing 10.

[0034] Pressing cantilever 14, the pressing cantilever 14 is located in the through hole 13 and one end is connected to the housing 10, the free end of the pressing cantilever 14 is movable in the through hole 13;

[0035] Cover 15 is disposed on part of the outer wall of the housing 10 and covers the through hole 13. Pressing the cover 15 drives the free end of the pressing cantilever 14 and triggers the micro switch 12.

[0036] The pressing cantilever 14 is disposed within the through hole 13, so that the switch structure is not visible from the outside of the housing 10, making the housing 10 more aesthetically pleasing and reducing its size. The microswitch 12 is triggered by a small swing of the pressing cantilever 14, and then the elasticity of the pressing cantilever 14 returns it to its original position. The structure is simple and ingeniously designed. Furthermore, the cover 15, disposed on the outer surface of the housing 10, conceals the through hole 13 and the pressing cantilever 14, making the outer surface of the housing 10 aesthetically pleasing and smooth.

[0037] The outer wall of the housing 10 is the outer surface of the side wall of the housing 10.

[0038] According to one embodiment of the micro-control switch structure disclosed herein, the pressing cantilever 14 is integrally formed with the housing 10. This simplifies the manufacturing process, and the integral forming of the pressing cantilever 14 and the housing 10 improves product quality and extends the service life of the pressing cantilever 14.

[0039] According to one embodiment of the micro-control switch structure disclosed herein, the pressing cantilever 14 protrudes from the wall of the through hole 13 and is disposed in the through hole 13, and a U-shaped gap 16 is formed between the wall of the through hole 13 and the outer edge of the pressing cantilever 14.

[0040] The pressing cantilever 14 is disposed in the through hole 13 to avoid the pressing cantilever 14 occupying the external space of the housing 10 and the internal space of the mounting cavity 11, and to prevent it from protruding on the outside of the housing 10 and squeezing the internal space of the mounting cavity 11. The U-shaped gap 16 provides room for the pressing cantilever 14 to swing, preventing the pressing cantilever 14 from being restricted by the wall of the through hole 13.

[0041] Specifically, an elastic sealant 17 is provided within the U-shaped gap 16. The elastic sealant 17 is integrally formed by a two-color injection molding process to connect the outer edge of the pressing cantilever 14 and the wall of the through hole 13. By providing the elastic sealant 17 in the U-shaped gap 16, the elastic sealant 17 can help the pressing cantilever 14 return to its original position after being pressed down, and it also serves a waterproof function.

[0042] According to one embodiment of the micro-control switch structure disclosed herein, the pressing arm 14 has a first surface and a second surface disposed opposite to each other. The first surface protrudes towards the cover 15 and a pressing member 18 extends outward. The end of the pressing member 18 contacts the inner surface of the cover 15. Pressing the pressing member 18 can move the pressing arm 14 and trigger the micro switch 12 on the second surface.

[0043] There is a predetermined distance between the first surface of the pressing cantilever 14 and the cover 15. By providing the pressing element 18 on the first surface to supplement the predetermined distance between the two, it is ensured that the cover 15 can drive the pressing cantilever 14 to sink under slight deformation, thereby triggering the micro switch 12 on the second surface of the cover 15.

[0044] Specifically, the first surface is also provided with a reinforcing rib 19 extending along the extension direction of the pressing arm 14, the reinforcing rib 19 extending from the pressing member 18 to the connection between the pressing arm 14 and the housing 10.

[0045] The reinforcing rib 19 can extend the service life of the pressing cantilever 14 and prevent the pressing cantilever 14 from breaking during use.

[0046] According to one embodiment of the micro-control switch structure disclosed herein, the cover 15 includes a connecting region 20 located on the periphery and a deformable region 21 surrounded by the connecting region 20. The inner surface of the connecting region 20 is fixed to the outer wall of the housing 10. The deformable region 21 covers the through hole 13 and can return to its original shape after the micro switch 12 is triggered and the pressing cantilever 14 rebounds.

[0047] By providing a cover 15, the manufacturing process of the housing 10 can be simplified. The cover 15, with its connecting area 20, can be fixed to the outer wall of the housing 10. The cover 15 can be a PVC film, and 3M adhesive is used in its connecting area 20 to fix the PVC film to the housing 10. The deformable area 21 is not bonded to the pressing spring arm, ensuring that the cantilever arm 14 quickly returns to its original shape after being pressed, thus maintaining a flat appearance for the cover 15.

[0048] Specifically, the cover 15 further includes a spacer 22, which is fixedly disposed on the side of the deformable area 21 corresponding to the through hole 13.

[0049] In practice, adhesive is provided in both the connection area 20 and the deformable area 21 of the cover 15, and then the spacer 22 is bonded to the deformable area 21. This can prevent the deformable area 21 from being mistakenly bonded with adhesive, thus preventing the deformable area 21 from being bonded to the cantilever 14.

[0050] According to one embodiment of the micro-switch structure disclosed herein, a push-button mark is provided on the cover 15 at a position corresponding to the micro switch 12. This is used to indicate the accurate position of the switch to the user. The push-button mark can be a different colored pattern or a recessed texture.

[0051] According to one embodiment of the micro-control switch structure disclosed herein, a switch bracket 23 is further included, which is fixed to the inner wall of the housing 10 for fixing the micro switch 12 to a predetermined position corresponding to the through hole 13.

[0052] In practice, the micro switch 12 is usually mounted on the circuit board 24, and the switch bracket 23 is used to support the circuit board 24 and thus support the micro switch 12.

[0053] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
