An arc-shaped oil groove 334 is provided on the outer peripheral wall surface of the locking hole 333. The limiting hole 332 is an internally open structure to facilitate the installation of the rocker 20. In a specific implementation, the limiting hole 332 can be a non-open structure on the inside, and only penetrates in the longitudinal direction, so that the rocker 20 can be installed from one longitudinal side.

[0035] The rocker 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 received 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 is formed with a pin hole 213 penetrating in the transverse direction, and the fixed section 212 has a non-cylindrical structure, preferably a square structure. The tail 214 has a cylindrical structure, and the outer diameters of the head 211, the fixed section 212, and the tail 214 decrease in sequence.

For example, it may only include the vertical portion 221 without setting the horizontal portion 222, or directly extend from the head 211 in an inclined state.

[0037] The elastic member 40 can be a spring or a combination of multiple elastic components, and the elastic member 40 is sleeved outside the tail 214 of the rotating shaft 21. The positioner 50 includes a first positioning member 51 and a second positioning member 52 cooperating with the first positioning member 51. The first positioning member 51 includes a first main body 511 sleeved on the tail 214 of the rotating shaft 21, a first hole 512 longitudinally penetrating the first main body 511, and a pair of transposition grooves 513 formed at the front end of the first main body 511. Each transposition groove 513 includes a concave first transposition groove 5131, a second transposition groove 5132, and a spacer protrusion 5133 spacing the first transposition groove 5131 and the second transposition groove 5132. Both the first transposition groove 5131 and the second transposition groove 5132 have a smooth arc surface structure, and the spacer protrusion 5133 is located between the first transposition groove 5131 and the second transposition groove 5132, and the front end surface of the spacer protrusion 5133 is lower than the front end surface of the first main body 511.

The shape of the positioning convex portion 523 matches the shapes of the first transposition groove 5131 and the second transposition groove 5132.

[0039] Please continue to refer to Figure 6 、Figure 7 As shown, when the rocker mechanism of the present application is assembled, the sealing ring 23 is first sleeved on the outside of the head 211 of the rotating shaft 21, and then the tail of the rotating shaft 21 is inserted from the shaft hole 1221 and the through hole 1223 into the inner groove 131; the positioner 50 and the elastic member 40 are inserted from the tail 214, and the rotating shaft 21 is completely inserted into the inner groove 131; the toggle member 30 is inserted into the fixed section 212 of the rotating shaft 21 from the outside, and the toggle member 30 is fixed to the fixed section 212 of the rotating shaft 21 by passing the pin 34 through the lock hole 333 and the pin hole 213. At this time, the elastic member 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 inserted into the outside of the fixed section 212, the second positioning member 52 is fixed relative to the rotating shaft 21, and the second positioning member 52 rotates with the rotation of the rotating shaft 21; the first positioning member 51 is sleeved outside the tail portion 214 and is not fixed to the tail portion 214, but the first positioning member 51 is fixed to the housing 10 so that the first positioning member 51 cannot rotate; 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 surface of the inner groove 131 to provide elastic force. The positioning protrusion 523 of the second positioning member 52 is inserted into the first transposition groove 5131 or the second transposition groove 5132 of the first positioning member 51.

[0040] The working principle of the rocker mechanism of this application is as follows:

[0041] The toggle protrusion 32 of the toggle member 30 drives the rotating shaft of the rocker arm 20 and the follower rod 22 to rotate together, thereby overcoming the elastic force of the elastic member 40, so that the positioning protrusion 523 of the second positioning member 52 moves from the first transposition groove 5131 to the second transposition groove 5132, or shifts from the second transposition groove 5132 to the first transposition 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 transposition groove 5131 and the second transposition groove 5132, it can correspond to a closed state and a conductive state respectively.

[0042] The present application also includes a head-mounted device and a rocker switch, wherein the rocker switch includes the rocker mechanism of the present application and a physical switch (not shown), and the physical switch is turned on or off by changing the position of the follower rod 22 of the rocker mechanism to achieve the complete function of the switch. The physical switch can be a rocker switch or a rocker switch, etc., as long as the follower rod 22 can be used to open or close the physical switch.

[0043] The head-mounted device of the present application includes a device housing (not shown), electronic components disposed within the device housing (not shown), the physical switch fixed within the device housing, and the rocker mechanism. The device housing is provided with an opening for mounting the rocker mechanism. The rocker mechanism is snapped into the opening of the device housing through an adhesive sticker on the inner surface of the housing 10 and fixed by the adhesive sticker. Of course, in addition to the adhesive sticker, other locking methods can also be used to assemble the rocker mechanism into the device housing. After being assembled within the device housing, the toggle member 30 is toggled to rotate the rotating shaft 21 and cause the positioning protrusion 523 of the second positioning member 52 to switch between the first switching slot 5131 and the second switching slot 5132 of the first positioning member 51, so that the follower rod 22 rotates to achieve switching between 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.

[0044] It should be noted that the positions of the first positioning member 51 and the second positioning member 52 of the rocker mechanism can be interchanged. Only one positioning member needs to rotate with the rotating shaft 21, and one positioning member is 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).

[0045] The rocker mechanism, rocker switch and head-mounted device of the present application indirectly control the physical switch through a rocker mechanism that is convenient to assemble from the outside, which not only ensures the consistency of the housing material, appearance and texture, but also enables the physical switch to be well protected within the device housing and not easily contaminated.

[0046] In one embodiment, the opening of the device housing has a sunken structure, that is, the housing 10 of the rocker switch can be sunk into the opening without protruding outside the device housing, and only the toggle protrusion 32 of the toggle member 30 protrudes outside, ensuring the beauty of the product.

[0047] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.

[0048] The above embodiments only express the preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
