[0027] Please continue reading. Figures 1 to 5 As shown, the rocker arm mechanism of this application includes a housing 10, a rocker arm 20, a toggle member 30 rotatably fixed outside the housing 10 via the rocker arm 20, a positioner 50 limiting the rocker arm 20 to different positions, and an elastic member 40 providing a certain elastic force to the positioner 50.

[0028] The housing 10 includes a flat base plate 11, an arc-shaped first outward protrusion 121 and a second outward protrusion 122 protruding outward from both longitudinal ends of the base plate 11, an inward recess 13 formed by recessing inward from the middle of the longitudinal direction of the base plate 11 between the first outward protrusion 121 and the second outward protrusion 122, and a through hole 1223 passing through the second outward protrusion 122 and communicating with the inward recess 13.

[0029] The second protruding portion 122 is located on the front side, and the first protruding portion 121 is located on the rear side. The concave portion 13 is recessed inward to form an inner groove 131. The first protruding portion 121 has an end limiting groove 1211 on the side near the inner groove 131. The end limiting groove 1211 is open to the outside, or it is not open to the outside and only communicates with the inner groove 131. The inner side of the second protruding portion 122 is recessed outward to form a shaft hole 1221. The through hole 1223 can be part of the shaft hole 1221 to communicate with the inner groove 131. The inner side of the shaft hole 1221 is open, and a first sealing groove 1222 is formed on the inner wall surface of the shaft hole 1221. The inner diameter of the first sealing groove 1222 is larger than the inner diameter of the through hole 1223. The shaft hole 1221 communicates with the inner groove 131 through the through hole 1223 and corresponds to the end limiting groove 1211. The vertical depth of the inner groove is greater than the bottom edge of the through hole 1223 and the end limiting groove 1211.

[0030] The adhesive 14 is adhered to the inner surface of the housing 10. The adhesive 14 includes an adhesive body 141 that adheres to the outer periphery of the inner surface of the housing 10 and a notch 142 corresponding to the shaft hole 1221. The inner surface of the housing 10 bulges inward in the middle to form the recess 13, and the adhesive body 141 is adhered to the outer periphery of the inner surface of the housing 10 located on the outer periphery of the recess 13.

[0031] The actuating element 30 includes a cover 31 covering the outer surface of the housing 10, an actuating protrusion 32 protruding outward from the cover 31, and a locking part 33 extending inward from the inner side of the cover 31. The cover 31 is generally arc-shaped and covers the outer side of the recess 13 of the housing 10 and is rotatable. The locking part 33 includes a pair of limiting walls 331 protruding inward from the inner wall of the cover 31, a limiting hole 332 formed between the pair of limiting walls 331, and a locking hole 333 penetrating through the pair of limiting walls 331. An arc-shaped oil groove 334 is formed on the outer peripheral wall of the locking hole 333. The limiting hole 332 is an internally open structure to facilitate the installation of the rocker arm 20. In specific implementation, the limiting hole 332 can be an internally closed structure, only penetrating in the longitudinal direction, so that the rocker arm 20 can be installed from the longitudinal side.

[0032] The rocker arm 20 includes a rotating shaft 21 and a follower rod 22 integrally fixed to the rotating shaft 21. The rotating shaft 21 includes a head 211 housed in a shaft hole 1221 of the housing 10, a fixed section 212 extending rearward from the head 211, and a tail 214 extending rearward from the fixed section 212. The fixed section 212 has a pin hole 213 extending through it in the transverse direction. The fixed section 212 is a non-cylindrical structure, preferably a square structure. The tail 214 is a cylindrical structure, and the outer diameters of the head 211, the fixed section 212, and the tail 214 decrease sequentially. A second sealing groove 215 is formed on the outer periphery of the head 211, and a sealing ring 23 is fitted inside the second sealing groove 215.

[0033] The follower rod 22 includes a vertical portion 221 integrally formed in a radial direction from the outer peripheral surface of the head 211, and a horizontal portion 222 formed by vertically bending the end of the vertical portion 221 and extending horizontally with the rotating shaft 21. In some embodiments, the shape of the follower rod 22 is not limited, and its structural form can be adjusted according to the usage scenario. For example, it may only include the vertical portion 221 without the horizontal portion 222, or it may be directly formed by the head 211 extending in an inclined state.

[0034] The elastic element 40 can be a spring or a combination of multiple elastic components, and the elastic element 40 is sleeved on the tail 214 of the rotating shaft 21. The positioner 50 includes a first positioning element 51 and a second positioning element 52 that cooperates with the first positioning element 51. The first positioning element 51 includes a first body 511 sleeved on the tail 214 of the rotating shaft 21, a first hole 512 longitudinally penetrating the first body 511, and a pair of shifting grooves 513 formed at the front end of the first body 511. Each shifting groove 513 includes a recessed first shifting groove 5131, a second shifting groove 5132, and a spaced protrusion 5133 separating the first shifting groove 5131 and the second shifting groove 5132. Both the first transposition groove 5131 and the second transposition groove 5132 have a smooth arc surface structure, and the interval protrusion 5133 is located between the first transposition groove 5131 and the second transposition groove 5132.

[0035] The second positioning member 52 includes a second body 521, a second hole 522 extending longitudinally through the second body 521, and a positioning protrusion 523 protruding rearward from the rear end of the second body 521. The shape of the positioning protrusion 523 matches the shapes of the first shift groove 5131 and the second shift groove 5132.

[0036] Please continue reading. Figure 6 , Figure 7As shown, during the assembly of the rocker arm mechanism of this application, the sealing ring 23 is first fitted onto the head 211 of the rotating shaft 21, and then the tail of the rotating shaft 21 is inserted into the inner groove 131 through the shaft hole 1221 and the through hole 1223; the positioner 50 and the elastic element 40 are fitted onto the tail 214, and the rotating shaft 21 is fully inserted into the inner groove 131; the actuating element 30 is inserted into the fixed section 212 of the rotating shaft 21 from the outside, and the actuating element 30 is fixed onto the fixed section 212 of the rotating shaft 21 by the pin 34 passing through the locking hole 333 and the pin hole 213. At this time, the elastic element 40 will be compressed, and the first The second hole 522 of the second positioning member 52 is a non-circular structure and matches the shape of the fixed section 212. When the second positioning member 52 is fitted onto the fixed section 212, the second positioning member 52 is fixed relative to the rotating shaft 21 and rotates with the rotation of the rotating shaft 21. The first positioning member 51 is fitted onto the tail 214 but is not fixed to the tail 214. However, the first positioning member 51 is locked to the housing 10, making it non-rotatable. One end of the elastic member 40 abuts against the rear end of the first positioning member 51, and the other end abuts against the rear wall of the inner groove 131 to provide elastic force. The positioning protrusion 523 of the second positioning member 52 is engaged in the first shifting groove 5131 or the second shifting groove 5132 of the first positioning member 51.

[0037] The working principle of the rocker arm mechanism in this application is as follows:

[0038] By actuating the actuating protrusion 32 of the actuating member 30, the rotating shaft of the rocker arm 20 and the follower rod 22 rotate together, thereby overcoming the elastic force of the elastic member 40 and causing the positioning protrusion 523 of the second positioning member 52 to move from the first switching groove 5131 to the second switching groove 5132, or to switch from the second switching groove 5132 to the first switching groove 5131 to achieve position switching. During the position switching process, the position of the follower rod 22 changes, that is, when the positioning protrusion 523 is located in the first switching groove 5131 and the second switching groove 5132, it can correspond to a closed state and a connected state, respectively.

[0039] This application also includes a head-mounted device and a rocker switch. The rocker switch includes the rocker mechanism of this application and a physical switch (not shown). The physical switch is opened or closed by changing the position of the follower rod 22 of the rocker mechanism to achieve the full function of the switch. The physical switch can be a rocker switch or a rocker switch, as long as the opening and closing of the physical switch can be achieved by the follower rod 22.

[0040] The head-mounted device of this application includes a device housing (not shown), electronic components placed inside the device housing (not shown), a physical switch fixed inside the device housing, and a rocker arm mechanism. The device housing has an opening for mounting the rocker arm mechanism. The rocker arm mechanism is inserted into the opening of the device housing via adhesive tape on the inner surface of the housing 10 and fixed by the adhesive tape. Alternatively, other locking methods can be used to assemble the rocker arm mechanism into the device housing. After assembly into the device housing, the actuating member 30 is moved, causing the rotating shaft 21 to rotate and the positioning protrusion 523 of the second positioning member 52 to switch between the first shifting groove 5131 and the second shifting groove 5132 of the first positioning member 51. This causes the follower rod 22 to rotate, switching between the two positions. When switched to the closed state, the follower rod 22 opens the physical switch to achieve conduction; when switched to the closed state, the follower rod 22 disengages from or closes the physical switch to achieve disconnection.

[0041] It should be noted that the positions of the first positioning member 51 and the second positioning member 52 of the rocker arm mechanism can be interchanged. Only one positioning member needs to rotate with the rotating shaft 21, and the other positioning member needs to be non-rotatable relative to the rotating shaft 21 (that is, one positioning member is limited by the rotating shaft and the housing 10 and cannot rotate with the rotating shaft).

[0042] The rocker arm mechanism and rocker arm switch of this application, i.e., the head-mounted device, indirectly control the physical switch through a rocker arm mechanism that is easy to assemble from the outside. This ensures the consistency of the shell material, appearance, and texture, while also protecting the physical switch inside the device shell from contamination.

[0043] In one embodiment, the opening of the device housing is a recessed structure, which means that the housing 10 of the rocker switch is recessed into the opening without protruding from the device housing, and only the toggle protrusion 32 of the toggle member 30 protrudes outward, thus ensuring the aesthetics of the product.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
