The invention provides a binding band adjusting device, which comprises an upper shell 10, a binding band assembly 20, a sliding assembly 30, a connecting piece 50 and a driving assembly 40, wherein an accommodating cavity 13 is formed in the upper shell 10, a sliding groove 12 is formed in the side wall of the upper shell 10, and the sliding groove 12 is communicated with the accommodating cavity 13; the strap assembly 20 is arranged in the accommodating cavity 13; the sliding assembly 30 is movably arranged on the chute 12; one end of the connecting member 50 is connected to the sliding assembly 30, and the other end extends toward the strap assembly 20; the driving assembly 40 is disposed on the sliding assembly 30, and the driving assembly 40 is connected with the connecting member 50; the drive assembly 40 is used to drive the connector 50 to move into abutment with the strap assembly 20 or to drive the connector 50 to retract from the strap assembly 20; when the connecting piece 50 abuts against the strap assembly 20, the sliding assembly 30 slides and drives the strap assembly 20 to shrink.

Referring to fig. 1, the sliding assembly 30 is mounted on the outer side of the upper case 10. Specifically, the casing is provided with an opening 11, and the opening 11 is communicated with the chute 12. The slide assembly 30 is then mounted in the opening 11. The opening 11 is sized larger to facilitate the reciprocal movement of the slide assembly 30 within the opening 11.

The sliding component 30 extends out of the upper shell 10 through the opening 11, and the sliding component 30 is exposed out of the upper shell 10, so that the operation of tightening and loosening the binding bands can be conveniently realized by using bare hands to interact with the sliding component 30.

Referring to fig. 2, the strap assembly 20 is installed in the accommodating cavity 13 of the upper case 10, so as to avoid interference with other mechanisms to affect shrinkage.

The strap assembly 20 extends from both ends of the upper case 10 to be connected to an external headband 60 for a user to wear on the head.

The connector 50 is used to connect the strap assembly 20 with the slide assembly 30. So that the sliding assembly 30 drives the strap assembly 20 to move during sliding, and thus drives the external headband 60 to synchronously shrink.

As an example, the strap assembly 20 may be fixed to the upper case 10 at one end and connected to the connector 50 at the other end. When the sliding assembly 30 drives the connecting piece 50 to move, the other end of the strap assembly 20 is pulled to move. Referring to fig. 1, the band assembly 20 is tightened when the sliding assembly 30 moves leftwards, and the band assembly 20 is loosened when pulled rightwards. The mode is simple and compact in structure, but small in adjusting range.

Thus, referring to fig. 2, as another example, the strap assembly 20 may include a first strap 21 and a second strap 22, the first strap 21 being configured to be coupled to one end of the outer band 60 and the second strap 22 being configured to be coupled to the other end of the outer band 60. By means of the cooperation of the gears 23, when the sliding assembly 30 moves leftwards, the two binding bands move towards each other; so that both ends of the outer headband 60 are simultaneously tightened, and when moving rightward, both bands move away from each other, so that both ends of the outer headband 60 are simultaneously loosened. The mode can increase the adjusting range by times and improve the compatibility of products.

The drive assembly 40 is used to drive the connection between the connector 50 and the strap assembly 20.

When the user has finished using the outer band 60, the connector 50 can be disengaged from the strap assembly 20 by the drive assembly 40 when the user needs to return the outer band 60 to its original length. Thereby effecting repositioning of the strap assembly 20.

To achieve the return function of the strap assembly 20, the straps in the strap assembly 20 may be made of a resilient plastic material such as plastic. Or the reset function can be realized by adopting a spring and other structures.

In this embodiment, the first strap 21 and the second strap 22 are made of a material such as polyethylene, so as to have resilience.

The gear 23 is clamped between the first strap 21 and the second strap 22. And the gear 23 is engaged with the first rack 211 and the second rack 221, respectively. Thus, when the gear 23 rotates, the first strap 21 and the second strap 22 are driven to move toward each other or away from each other.

The third rack 222 may be disposed on the first strap 21 or on the second strap 22. In this embodiment, the third rack 222 is disposed on the second strap 22.

When the driving assembly 40 drives the connecting piece 50 to move to be abutted against the second binding belt 22, the connecting piece 50 is clamped in the tooth groove of the third rack 222, and when the sliding assembly 30 drives the connecting piece 50 to move, the second binding belt 22 can be driven to move through the clamped tooth groove; under the action of the gear 23, the first binding belt 21 is driven to move synchronously.

When the driving assembly 40 drives the connecting piece 50 to disengage from the tooth slot, the limiting effect of the connecting piece 50 on the second binding band 22 disappears, and under the rebound plasticity effect of the second binding band 22, the second binding band 22 resets, and the gear 23 drives the first binding band 21 to synchronously reset.

Further, the sliding assembly 30 includes a guide rod 31, a slider 32, and a reset member 33, where the guide rod 31 is disposed in the chute 12; the sliding block 32 is movably arranged on the guide rod 31; one end of the reset piece 33 is connected with the end part of the guide rod 31, and the other end is connected with the sliding block 32; the connector 50 is disposed on a side of the slider 32 facing the strap assembly 20, the drive assembly 40 is disposed on a side of the slider 32 facing away from the strap assembly 20, and the drive assembly 40 is connected to the connector 50.

The guide rods 31 are arranged in an arc shape for adapting to the curve of the head of the user. Both ends of the guide rod 31 are respectively fixed to the left and right side walls of the chute 12.

The sliding block 32 is provided with a through hole, and the guide rod 31 is penetrated in the through hole, so that the sliding block 32 slides on the guide rod 31.

The restoring member 33 may be a spring, and is sleeved on the guide rod 31, one end of the restoring member is connected with an end portion of the guide rod 31 or connected with a side wall of the chute 12, and the other end of the restoring member is connected with the slider 32.

Referring to fig. 2, the reset member 33 is disposed between the slider 32 and the left side wall of the chute 12, and the user moves the slider 32 to the left to adjust the tightness of the strap assembly 20. By the restoring member 33, the slider 32 is pushed to the right to the initial position by the restoring member 33 after the user removes the force from the slider 32.

With the third rack 222 engaged, the connecting member 50 is pushed into the tooth space on the right side of the third rack 222 by the restoring member 33, and the second strap 22 is restrained.

If the user continues to tighten the strap assembly 20, the user may continue to push the slider 32 to move leftwards, and reset under the action of the reset member 33. And so on, repeatedly pushing the slider 32 to the left a plurality of times until the tightness of the fit is adjusted.

In this embodiment, the resetting piece 33 resets the slider 32, and the third rack 222 is matched with the slider, so that the user can adjust the tightness multiple times, and the compatibility of products is further improved.

As a further embodiment, a button 41 is installed at the outward side of the slider 32, and the connector 50 is installed at the bottom of the button 41. So that when the user presses the button 41, the connector 50 is pushed to move toward the inside of the upper case 10, and finally abuts against the strap assembly 20. When the user switches button 41 back, the connector 50 then disengages the strap assembly 20 with the button 41.

As yet another embodiment, referring to fig. 4, the driving assembly 40 includes a button 41, a torsion spring 42, a first magnet block 43 and a second magnet block 44, wherein the button 41 is disposed at a side of the slider 32 facing away from the strap assembly 20; the torsion spring 42 is disposed on a side of the slider 32 facing the strap assembly 20, and the connector 50 is connected to the torsion spring 42; the magnet block is arranged on the side of the button 41 facing the connecting piece 50; the second magnet block 44 is arranged on the connecting piece 50; when the button 41 is pressed, the first magnet 43 is driven to move to the side of the connecting piece 50, so that the first magnet 43 attracts the second magnet 44 and drives the connecting piece 50 to retract from the strap assembly 20; when the button 41 is released, the first magnet 43 is driven to move towards the side away from the connecting piece 50, so that the first magnet 43 is separated from the second magnet 44, and the connecting piece 50 moves to abut against the binding band assembly 20 through the torsion spring 42.

In contrast to this embodiment, when the user presses the button 41, the first magnet 43 is pushed to the strap assembly 20 side, the adsorption force between the first magnet 43 and the second magnet 44 increases, and overcomes the resistance of the torsion spring 42, so that the first magnet 43 adsorbs the second magnet 44, and the connecting piece 50 is separated from the third rack 222, and the strap assembly 20 is reset.

When the user does not press the button 41, the first magnet 43 moves in the opposite direction, the distance between the first magnet and the second magnet 44 increases, and the adsorption force decreases. The connecting piece 50 is pushed to the third rack 222 under the action of the torsion spring 42, and is clamped into the tooth slot of the third rack 222, so as to limit the strap assembly 20.

In this manner, the user can effect tightness adjustment of the strap assembly 20 without touching the button 41; when the reset is required, the button 41 may be pressed. Thereby further improving the use convenience of the user and the structural rationality.

Specifically, the slider 32 has a certain thickness so as to accommodate the first magnet block 43. The button 41 is provided with a first mounting groove 45 on a side facing the connection member 50, and the first magnet piece 43 is disposed in the first mounting groove 45.

A convex boss is provided on a side of the connection member 50 facing the slider 32, and an inside of the boss is hollow, thereby realizing the fabrication of the second mounting groove 51.

In addition, in order to solve the problems, the invention also provides a VR device, and the VR device is applied with the binding band adjusting device. The sliding assembly 30 is mounted on the outside of the upper case 10. Specifically, the casing is provided with an opening 11, and the opening 11 is communicated with the chute 12. The slide assembly 30 is then mounted in the opening 11. The opening 11 is sized larger to facilitate the reciprocal movement of the slide assembly 30 within the opening 11.

The strap assembly 20 is mounted in the receiving cavity 13 in the upper shell 10 to avoid interference with other mechanisms to affect shrinkage.

Thus, as another example, the strap assembly 20 may include a first strap 21 for connection with one end of the outer band 60 and a second strap 22 for connection with the other end of the outer band 60. By means of the cooperation of the gears 23, when the sliding assembly 30 moves leftwards, the two binding bands move towards each other; so that both ends of the outer headband 60 are simultaneously tightened, and when moving rightward, both bands move away from each other, so that both ends of the outer headband 60 are simultaneously loosened. The mode can increase the adjusting range by times and improve the compatibility of products.
