The head-mounted device with the detachable part provided by the embodiment of the present invention is further introduced in detail below.

FIG. 2 is a schematic structural diagram of the detachable part 30 of the embodiment of the present invention. FIG. 2 shows a realization structure of a buckle structure 32 .

Specifically, the buckle structure 32 includes: a columnar body 33 wrapped outside the second electrical connection part 31 and anti-off teeth 34 provided on the columnar body 33 . The anti-off tooth 34 passes through the mounting hole 41 through the notch 42 and snaps into the limiting cavity.

During installation, the anti-off teeth 34 are aligned with the gap 42 , and when the columnar body 33 enters the installation hole 41 , the anti-off teeth 34 also enter the gap 42 . In actual implementation, the shape of the notch 42 can match the shape of the anti-off tooth 34 . After the anti-off tooth 34 enters the end of the notch 42 , it enters and snaps into the limiting cavity, so as to realize the connection between the buckle structure 32 and the locking member 40 . Through the combined effect of the anti-off teeth 34 and the limiting cavity, the combination between the hook structure 32 and the locking element 40 is more firm, thereby realizing the connection and anti-off function between the detachable element 30 and the headwear assembly 20 . The embodiment of the utility model does not specifically limit the shape of the anti-off tooth 34 and the notch 42 , as long as they match each other, the anti-off tooth 34 can move along the notch 42 to meet the requirements of the present invention. For example, the shapes of the anti-off teeth 34 and the notches 42 include but are not limited to rectangular structures, zigzag structures, concave-convex structures, wavy structures and other shapes and structures.

Since the buckle structure 32 needs to be rotated when it enters the limiting cavity, in order not to affect the connection between the first electrical connection part 21 and the second electrical connection part 31, in the embodiment of the utility model, a possible way Yes, the columnar body 33 can rotate relative to the second electrical connection part 31 . In actual implementation, after the buckle structure 32 enters the mounting hole 41, the first electrical connection part 21 communicates with the second electrical connection part 31, and under the action of an external rotational force, the columnar body 33 drives the anti-off teeth 34 to rotate into the In the limiting cavity, the second electrical connection part 31 does not rotate, ensuring a stable connection with the first electrical connection part 21 . In the embodiment of the present utility model, the first electrical connection part 21 is a socket. The second electrical connection part 31 is a plug. Specifically, the plug is a retractable plug. For example, the second electrical connection part 31 is a Pogo pin. The Pogo pin is a spring-type probe formed by riveting and pre-pressing three basic parts of a needle shaft, a spring, and a needle tube through a precision instrument. There is a precision spring inside it. structure.

Another implementation is that the first electrical connection part 21 is rotatably connected to the headwear assembly 20, and under the action of an external rotational force, the columnar body 33 drives the anti-off teeth 34 to rotate into the limiting cavity, and the second electrical connection The portion 31 drives the first electrical connection portion 21 to rotate, so as to achieve a stable connection between the second electrical connection portion 31 and the first electrical connection portion 21 .

Referring to Fig. 3, in the embodiment of the present utility model, the form of the limiting cavity includes various forms. One possible way is that the locking member 40 is provided with a through hole, and the through hole is provided with a limiting cavity coaxial with the through hole. Ring 43. The inner hole of the limiting ring 43 forms the installation hole 41 . The limiting ring 43 is connected on the inner wall of the through hole through the outer ring.

A notch 42 is formed on the inner wall of the limiting ring 43 . The limiting ring 43 is located at the entrance of the through hole, and the axial dimension of the limiting ring 43 is smaller than the axial dimension of the through hole to form a limiting cavity. For example, the annular surface of the side of the limiting ring 43 facing the detachable part 30 is flush with the plane of the locking part 40 facing the detachable part 30, and the annular surface of the limiting ring 43 facing the side of the headwear assembly 20 is lower than the lock. The fastener 40 faces the plane of the headgear assembly 20 .

In order to prevent the buckle structure 32 from coming out of the limiting cavity, in the embodiment of the present invention, at least two limiting protrusions 44 are provided on the end surface of the limiting ring 43 facing the headwear assembly 20 . After the hook structure 32 enters the limiting cavity, it is located between any two adjacent limiting protrusions 44 among the at least two limiting protrusions 44 . A kind of mode that can realize is, on the limit ring 43, the both sides of gap 42 are all provided with limit projections 44, when the buckle structure 32 enters the limit cavity, need to pass through the limit projections 44. For example, when the buckle structure 32 enters the limiting cavity through the anti-off teeth 34, there will be a "click" sound when passing through the limiting protrusion 44, and the user will also feel a "click" when rotating, indicating that The anti-off tooth 34 has entered the limiting cavity. After the anti-off tooth 34 enters the limiting cavity, due to the effect of the limiting protrusion 44, there is no external rotational force, so the anti-off tooth 34 cannot escape from the limiting cavity. Simultaneously, in order to ensure that the buckle structure 32 can pass through the position-limiting protrusion 44 smoothly, and reduce the friction between the position-limiting protrusion 44 and the buckle structure 32, the contact surface of the position-limiting protrusion 44 and the anti-off tooth 34 is a smooth curved surface. .

After the buckle structure 32 enters the limiting cavity, it may rotate. In order to limit the rotation of the buckle structure 32 in the limiting cavity, and then ensure that the detachable part 30 is fixed at a certain angle after the installation is completed, so in A structure that restricts the rotation of the hook structure 32 needs to be provided in the limiting cavity. One possible way is that the end surface of the limiting ring 43 facing the headwear assembly 20 is wave-shaped, and the hook structure 32 is located at the trough of the wave-shaped end surface after entering the limiting cavity. For example, when the buckle structure 32 enters the limiting cavity through the anti-off teeth 34, the anti-off teeth 34 enter the trough position of the wave-shaped end face, and the movement of the anti-off teeth 34 can be restricted by the trough, thereby limiting the buckle structure 32 in the position-limiting position. Rotation occurs in the cavity.

There are many ways to connect the locking member 40 and the head-mounted assembly 20 , for example, connecting through a fixing member or buckling.

Taking the connection of the fixing part as an example, at least one mounting column 45 is provided on the end surface of the locking part 40 facing the headwear assembly 20 . The headwear assembly 20 is provided with a mounting hole 41 . The mounting post 45 penetrates into the mounting hole 41 and realizes the connection between the locking member 40 and the headset assembly 20 through the fixing member. In order to increase the connection strength of the mounting column 45 , a plurality of support plates are arranged on the outer periphery of the mounting column 45 . Fasteners include but are not limited to screws.

Referring to FIG. 4 , a groove 22 is provided at a position corresponding to the mounting hole 41 on the headwear assembly 20 , and the first electrical connection is provided at the bottom of the groove 22 . The notch size of the groove 22 is larger than the size of the mounting hole 41 . The opening end surface of the installation hole 41 facing the headwear assembly 20 and the groove 22 form a limiting cavity. The depth of the limiting cavity increased by the groove 22 can make the connection between the hook structure 32 and the limiting cavity more firm and stable.

To sum up, in the technical solution provided by the embodiment of the utility model, the detachable connection between the main body of the device and the detachable part can be realized through the locking part and the buckle structure, the operation is simple, and the detachable part can be flexibly replaced on the main body of the device.
