The gear 133 is engaged with teeth of the inner sidewall of the guide groove 112. When the telescopic arms 111 move towards or away from each other, the gear 133 rotates along the guide groove 112. The gear 133 rotates to drive the rotary disc 13 to rotate, and correspondingly, when the rotary disc 13 is limited, the gear 133 cannot move relative to the guide groove 112, so that the relative positions of the two telescopic arms 111 are locked.

It will be appreciated that in other ways, the guide slots 112 may be omitted. The two telescopic arms 111 may be staggered relatively, and opposite sides of the two telescopic arms 111 are engaged with the gear 133. Therefore, as long as both telescopic arms 111 can be simultaneously engaged with the gear 133, when both telescopic arms 111 are relatively moved, the gear 133 can be driven to rotate.

Baffle 14 is provided on the surface of disk 13 facing gear holder 12, i.e. baffle 14 is provided on upper surface 131 of disk 13. The baffle 14 is a plate-like structure having a special shape. Specifically in this embodiment, the baffle 14 is provided with an arcuate outer surface 143. The edge of the baffle 14 is also provided with a notch 141. The baffle 14 is provided with a fitting hole 142. The baffle plate 14 is mounted on the turntable 13 through the mounting hole 142. The position of the fitting hole 142 of the baffle plate 14 coincides with the center of the rotary table 13. The shutter 14 rotates around the center of the rotary table 13.

Referring to fig. 2 and fig. 4, the first locking pin 16 and the second locking pin 17 are rotatably disposed on the upper surface 131 of the rotating disc 13. Specifically, two positioning columns 130 are disposed on the rotary table 13, and the first locking pin 16 and the second locking pin 17 are rotatably disposed on the rotary table 13 through the positioning columns 130, respectively.

Referring to fig. 5 and 6, the upper surface 131 of the rotating disc 13 faces the receiving groove 122 of the gear rack 12. The first engaging leg 16 and the second engaging leg 17 on the upper surface 131 of the rotating disc 13 are both accommodated in the accommodating groove 122, and the engaging groove 123 provided on the inner sidewall of the accommodating groove 122 is located on the outer periphery of the upper surface 131 of the rotating disc 13, so that the first engaging leg 16 and the second engaging leg 17 can be opposite to the engaging groove 123. When the first engaging portion 16 and the second engaging portion 17 are respectively abutted against the engaging groove 123 of the gear bracket 12 and the baffle 14, the baffle 14 is limited. At this time, even if the two telescopic arms 111 are pulled, since the first clamping leg 16 and the second clamping leg 17 provide two clamping forces to the rotary table 13 at the same time, the moment for pulling the two telescopic arms 111 is not enough to rotate the baffle 14, so that the first clamping leg 16 and the second clamping leg 17 are stably clamped with the gear bracket 12, and the self-locking of the head-mounted device bracket is realized.

Referring to fig. 4, the first engaging portion 16 and the second engaging portion 17 are respectively disposed on two opposite sides of the baffle 14. The baffle 14 rotates to drive the first engaging portion 16 and the second engaging portion 17 to rotate respectively, and the first engaging portion 16 and the second engaging portion 17 rotate in the same direction. The first engaging leg 16 and the second engaging leg 17 are respectively disposed on opposite sides of the axis of symmetry of the baffle 14. When the baffle 14 rotates, the rotation angle of the first clamping leg 16 is the same as that of the second clamping leg 17.

Referring to fig. 2 and 4, in the present embodiment, the first engaging portion 16 includes a first connecting end 162 connected to the baffle 14 and a first engaging end 161 engaged with the engaging groove 123. The second engaging portion 17 includes a second connecting end 172 connected to the baffle 14 and a second engaging end 171 engaged with the engaging groove 123. The first holding end 161 abuts against the first elastic member 181, the second holding end 171 abuts against the second elastic member 182, the first elastic member 181 has a pressure effect on the first holding end 161, and the second elastic member 182 has a pressure effect on the second holding end 171, so that the first connecting end 162 and the second connecting end 172 are pressed against the baffle 14. The first clamping end 161 and the second clamping end 171 are respectively clamped with the clamping groove 123, so that the two telescopic arms 111 are in limited connection, and the self-locking structure enables the head-mounted device support to be in a self-locking state. The first elastic member 181 and the second elastic member 182 may be compression springs or other elastic compression members.

Referring to fig. 4, the baffle 14 rotates to drive the first engaging portion 16 and the second engaging portion 17 to rotate. The rotary disc 13 is provided with a limit boss 134, and the limit boss 134 is used for limiting the rotation of the baffle plate 14. The baffle 14 is provided with a notch 141, and the limit boss 134 is arranged in the notch 141. When the baffle 14 moves between the first unlocking position and the second unlocking position, two sides of the notch 141 of the baffle 14 are distributed to prop against two sides of the limiting boss 134 for limiting. Specifically, the notch 141 and the stopper boss 134 are substantially the same in shape and are both substantially fan-shaped. The limit boss 134 can stably abut against the rotary disk 13.

The baffle 14 rotates clockwise to the first unlocking position, and the inner side wall of one side of the notch 141 of the baffle 14 is abutted with the outer side surface of one side of the limiting boss 134. The first engaging portion 161 compresses the first elastic member 181 when the first engaging portion 16 rotates, and the first engaging portion 161 is disengaged from the engaging slot 123. The second connecting end 172 of the second clip 17 is separated from the baffle 14, the second elastic member 182 rotates the second clip 17 under the action of the elastic restoring force, and the second clip end 171 moves along the clip groove 123, so that the two telescopic arms 111 can move toward or away from each other along one direction.

Or, the baffle 14 rotates counterclockwise to the second unlocking position, and the inner side wall of the other side of the notch 141 of the baffle 14 is abutted to the outer side surface of the other side of the limit boss 134. The second locking pin 17 rotates to make the second locking end 171 compress the second elastic member 182, and the second locking end 171 is separated from the locking slot 123. The first connecting end 162 of the first clamping leg 16 is separated from the baffle 14. The first elastic member 181 rotates the first engaging portion 16 under the elastic restoring force, and the first engaging end 161 moves along the engaging slot 123, so that the two telescopic arms 111 can move toward or away from each other along the other direction. It is to be understood that the specific locations of the first unlock bit and the second unlock bit are not limited herein. Alternatively, the flapper 14 may be rotated counterclockwise to a first unlocked position and the flapper 14 may be rotated clockwise to a second unlocked position.

Meanwhile, the first clamping pin 16 or the second clamping pin 17 is matched with and clamped or separated from the clamping grooves 123 on the gear bracket 12 in the rotating process, so that the rotating sound and the tactile feedback of 'clicking' can be generated. Consequently, according to the feedback of rotatory sound, can be with originally uncontrollable sense of touch and feedback sound, through the elastic modulus of adjustment spring, different sense of touch when obtaining the rotatory knob of finger improves user experience.

In addition, in order to make the relative tightness of the two telescopic arms 111 better conform to the feedback sound, the slots 123 of the gear bracket 12 may be distributed and designed to have different density degrees. Specifically, the arc surface is provided with a loose section of the clamping groove 123 and a dense section of the clamping groove 123, and the distance between two adjacent clamping grooves 123 of the loose section of the clamping groove 123 is greater than the distance between two adjacent clamping grooves 123 of the dense section of the clamping groove 123. The density of the clamping grooves 123 at the sparse section of the clamping grooves 123 is less than that of the clamping grooves 123 at the dense section of the clamping grooves 123.

In addition, when the relative position between the two telescopic arms 111 just starts to be adjusted, the clamping pins can be correspondingly engaged with or disengaged from the sparse segments of the clamping grooves 123, so that the frequency of feedback sound generated by the clamping pins is low when the relative position is just started to be adjusted. After certain adjustment is carried out, the clamping pin moves to the clamping groove 123 dense section, the clamping pin is correspondingly matched and clamped or separated with the clamping groove 123 dense section, and the frequency of feedback sound generated by the clamping pin is high. Therefore, in the process of adjusting the tightness degree of the head-mounted device support, the collision frequency of the clamping pins and the gear support 12 can be reflected through feedback sound, the feedback sound is diversified, and the user experience is improved.

In addition, when the relative position between the two telescopic arms 111 just starts to be adjusted, the clamping feet can correspondingly dredge the sections with the clamping grooves 123, and the tightness of the head-mounted equipment support can be quickly adjusted. After carrying out one section and adjusting, need further carry out accurate the regulation to the elasticity of wear-type equipment support, then the interval of the tight section of draw-in groove 123 is less, can realize more accurate elasticity of adjusting wear-type equipment support.

When the baffle 14 is not driven to rotate and the baffle 14 is not subjected to external force, the first elastic member 181 rotates reversely under the action of elastic restoring force, the first connection end 162 pushes the baffle 14 to reset, and the baffle 14 resets and pushes the second clamping leg 17 to rotate. The first clamping end 161 of the first clamping pin 16 and the second clamping end 171 of the second clamping pin 17 are clamped with the clamping groove 123, and the first connecting end 162 and the second connecting end 172 are simultaneously pressed with the baffle 14, so that the baffle 14 is limited and cannot rotate, the head-mounted device support automatically restores to the self-locking state, and the operation is convenient.

Specifically, in the present embodiment, the first holding end 161 and the second holding end 171 are provided with a protrusion 163, and the protrusion 163 is adapted to the slot 123. The protrusion 163 may enable the card slot 123 to stably hold and position.

Referring to fig. 4, the inner sidewall of the slot 123 is an arc-shaped concave surface, the outer surface of the protrusion 163 is an arc-shaped convex surface, and the arc-shaped convex surface is matched with the arc-shaped concave surface, so that the fixture block can be stably clamped into the slot 123. When the protrusion 163 needs to slide relative to the slot 123, the arc-shaped concave surface of the slot 123 and the arc-shaped convex surface of the latch are designed, and the slot 123 are in smooth transition, so that the protrusion 163 can smoothly move from one slot 123 to the next slot 123, and the protrusion 163 slides along the slot 123. Under the condition that enough rotating acting force around the positioning column is applied to the second clamping leg 17, the second clamping part can smoothly slide to the next adjacent clamping groove 123 along the arc-shaped concave surface of the clamping groove 123.

Referring to fig. 4, in the present embodiment, the first connecting end 162 and the second connecting end 172 respectively abut against the arc-shaped outer surface 143 of the baffle 14. When the baffle 14 is rotated, the baffle 14 pushes the first clamping leg 16 or the second clamping leg 17 to rotate through the first connecting end 162 or the second connecting end 172. During the rotation of the first and

second pins

16 and 17, the first and second connection ends 162 and 172 slide along the arc-shaped outer surface 143 of the baffle 14. The arc-shaped outer surface 143 is kept smooth, so that the first clamping leg 16 and the second clamping leg 17 smoothly slide along the arc-shaped outer surface 143 of the baffle plate 14.
