[0038] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present invention.

[0040] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0041] In addition, in the embodiments of the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the embodiments of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0042] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0043] In addition, the technical solutions between the various embodiments of the present invention may be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in the field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the embodiments of the present invention.

[0044] At present, the straps of the integrated head-mounted device need to be able to adapt to the size and shape of different users' heads. Wearing comfort, stability, and adjustability are the key indicators for users to evaluate the integrated head-mounted device. The common straps of integrated head-mounted devices on the market mainly include: flexible elastic bands, which use the elastic band's own retractability to fix the head, but this method will keep the head circumference tight for a long time. As the head circumference increases, the reverse contraction force of the elastic band on the head will further increase, and the wearing comfort is not good; hard plastic straps, which shrink or relax the straps by adjusting the coordination of the gear rack to adjust the tightness of the integrated head-mounted device. However, when the straps are adjusted from tight to loose, as the head circumference increases, the corners of the straps need to have an open deformation process, and cannot complete the flexible change of the corner curvature of the straps through their own flexible deformation, and cannot adapt to the size of different head circumferences, which also affects the wearing comfort of the integrated head-mounted device.

[0045] In view of this, an embodiment of the present invention proposes a strap tension adjustment device and a wearable device, wherein a sliding belt that can slide is arranged in a sliding cavity of a shell, and the sliding belt is connected to the shell through an elastic component. In the process of pulling the sliding belt out of the sliding cavity, the elastic component will deform and generate a rebound force, so that the sliding belt has a tendency to rebound. After the user wears the head-mounted device on the head, the external force applied to the sliding belt disappears, and the sliding belt slides into the sliding cavity under the action of the rebound force of the elastic component, thereby tightening the head-mounted device to the head. The entire wearing process only requires pulling the sliding belt, which is simple and convenient to operate, and reduces the reverse contraction force of the sliding belt on the head, thereby improving the wearing comfort of the user. In addition, during the sliding process of the sliding belt, the shell will follow the sliding of the sliding belt and undergo adaptive deformation, thereby adapting to the head, thereby improving the wearing comfort of the user.

[0046] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0047] like Figure 1 As shown, an embodiment of the present invention provides a strap tension adjustment device, the strap tension adjustment device comprising:

[0048] Sliding belt 100;

[0049] A housing 200, wherein a sliding cavity having an entrance and an exit is formed inside the housing 200, and the sliding belt 100 is slidably connected to the sliding cavity; and

[0050] The elastic component 300 connects the shell 200 and the sliding belt 100; in the process of the sliding belt 100 sliding out of the sliding cavity from the entrance and exit, the elastic component 300 is deformed and generates elastic force so that the sliding belt 100 has a tendency to slide into the sliding cavity to tighten the sliding belt 100, and the shell 200 can follow the movement of the sliding belt 100 and generate adaptive deformation.

[0051] In the technical solution adopted in this embodiment, by setting a sliding belt 100 that can slide in the sliding cavity of the shell 200, the sliding belt 100 can be pulled out of the sliding cavity, thereby changing the length of the sliding belt 100 extending out of the sliding cavity, and then facilitating the user to wear the head-mounted device on the head. In addition, the sliding belt 100 is connected to the shell 200 through the elastic component 300. In the process of pulling the sliding belt 100 out of the sliding cavity, the elastic component 300 will deform and generate a rebound force, so that the sliding belt 100 has a tendency to rebound. After the user wears the head-mounted device on the head, the external force applied to the sliding belt 100 disappears, and the sliding belt 100 slides toward the sliding cavity under the action of the rebound force of the elastic component 300, thereby tying the head-mounted device to the head, canceling the setting of the rack, and preventing it from getting stuck. The entire wearing process only needs to pull the sliding belt 100, which is simple and convenient to operate, and reduces the reverse contraction force of the sliding belt 100 on the head, thereby improving the wearing comfort of the user. In addition, during the sliding of the sliding belt 100 , the housing 200 will follow the sliding of the sliding belt 100 and undergo adaptive deformation, thereby adapting to the head and improving the wearing comfort of the user.

[0052] Specifically, the strap adjustment device includes a sliding belt 100, a housing 200, and an elastic component 300. The housing 200 is provided with a sliding cavity, and the sliding belt 100 is slidably connected to the sliding cavity, and can slide out of the sliding cavity or slide into the sliding cavity through an entrance and exit, so that the length of the sliding belt 100 extending out of the sliding cavity can be adjusted by sliding the sliding belt 100, thereby adjusting the tightness of the strap to facilitate wearing by the user. In one embodiment, the material of the sliding belt 100 can be hard plastic or hard plastic, which is not limited here.

[0053] The elastic component 300 connects the shell 200 and the sliding belt 100. It can be understood that when the sliding belt 100 is slid away from the sliding cavity, the elastic component 300 will deform and generate a rebound force. After the external force disappears, the rebound force can drive the sliding belt 100 to slide toward the sliding cavity, so that the strap becomes tighter, thereby fixing the head-mounted device on the user's head. In other words, one function of the elastic component 300 is to provide a rebound force for the sliding belt 100. On the one hand, it can ensure that the sliding belt 100 can slide into the sliding cavity after the external force disappears, and on the other hand, it can tighten the strap so that the head-mounted device is fixed on the user's head. In one embodiment, the elastic component 300 can be a spring, an elastic sheet, etc., which is not limited here.

[0054] It should be noted that, during the sliding of the sliding belt 100, the housing 200 will follow the sliding of the sliding belt 100 and deform adaptively, so that it can better match the user's head and improve the wearing comfort of the user. In one embodiment, the housing 200 is elastic and can be made of elastic materials such as rubber or plastic, or can be designed as a fishbone structure to be elastic, which is not limited here.

[0055] As an optional method, multiple groups of elastic components 300 can be provided, and the multiple groups of elastic components 300 are arranged at intervals along the width direction of the sliding belt 100, so that sufficient elastic force can be increased to ensure the stretching or tightening of the sliding belt 100.

[0056] For example, refer to Figure 1 and Figure 6 In one embodiment of the present invention, a mounting cavity is formed inside the sliding belt 100, and the sliding belt 100 is provided with an avoidance hole 121 communicating with the mounting cavity. The elastic component 300 includes:

[0057] An elastic member 310, which is disposed in the mounting cavity and extends along the sliding direction of the sliding belt 100;

[0058] A flexible member 320, wherein the elastic member 310 is sleeved on the outside of the flexible member 320, the flexible member 320 extends along the sliding direction of the sliding belt 100, and one end of the flexible member 320 is connected to the housing 200; and

[0059] A pressing member 330, one end of the pressing member 330 passes through the avoidance hole 121 and is slidably connected to the housing 200, and the other end of the flexible member 320 is connected to the pressing member 330;

[0060] When the sliding belt 100 slides out of the sliding cavity from the entrance, the pressing member 330 presses the elastic member 310 so that the elastic member 310 is compressed and deformed to generate elastic force.

[0061] Specifically, the elastic component 300 includes an elastic member 310, a flexible member 320, and a pressing member 330. The elastic member 310 is slidably arranged, extending between the two ends of the sliding direction of the sliding belt 100, and can be deformed under the action of an external force to generate elastic force. To facilitate the arrangement of the elastic member 310, an installation cavity is arranged inside the sliding belt 100, which can provide an installation position for the elastic member 310 on the one hand, and can also limit the elastic member 310 to prevent the elastic member 310 from separating from the sliding belt 100 on the other hand. In one embodiment, the elastic member 310 can be a spring, an elastic sheet, etc., which is not limited here.

[0062] The flexible member 320 connects the housing 200 and the pressing member 330, and is sleeved on the outside of the elastic member 310 to fix the elastic member 310 in the installation cavity. The elastic force generated by the deformation of the elastic member 310 drives the curvature of the sliding belt 100 to change to adapt to the head circumference of the user. It can be understood that one end of the flexible member 320 is fixedly connected to the housing 200, and the other end of the flexible member 320 is fixedly connected to the pressing member 330. As an optional method, the flexible member 320 can be a flexible line, a flexible rope, etc., which is not limited here.

[0063] The pressing member 330 cooperates with the flexible member 320 to deform the elastic member 310, and the pressing member 330 is slidably connected to the housing 200. It can be understood that the pressing member 330 is slidably connected to the inner wall of the housing 200 and abuts against the end of the sliding belt 100, one end of the flexible member 320 is fixedly connected to the pressing member 330, and the other end of the flexible member 320 passes through the elastic member 310 along the extension direction (i.e., the sliding direction) of the elastic member 310 and is fixedly connected to the housing 200. In order to facilitate the connection between the pressing member 330 and the housing 200, an avoidance hole 121 is provided on the sliding belt 100, and the avoidance hole 121 communicates with the pipe installation cavity, so that the pressing member 330 can extend out of the installation cavity through the avoidance hole 121 and connect with the housing 200. In the initial state, the elastic member 310 is in a free length state, and the flexible member 320 is in an expanded state in the extension direction of the elastic member 310. When the sliding belt 100 is slid out of the sliding cavity, the pressing member 330 slides relative to the housing 200, and the flexible member 320 overlaps with the fixed end of the housing 200. Since the total length of the flexible member 320 is fixed, the overlap of the ends of the flexible member 320 shortens the length of the flexible member 320 in the extension direction of the elastic member 310, and the pressing member 330 abuts against the end of the elastic member 310, thereby compressing the elastic member 310, causing the elastic member 310 to deform and generate elastic force, thereby pulling the strap open to facilitate the user to wear. At this time, the sliding belt 100 has a tendency to rebound under the elastic force of the elastic member 310. After the user wears the head-mounted device on the head, the elastic member 310 is still in a compressed state and always has elastic force. Since the total length of the flexible member 320 remains unchanged, the elastic member 310 cannot push the pressing member 330 to move, but pushes the sliding belt 100 to move toward the sliding cavity until the strap is tightened and the wearing is completed, thereby achieving the fixation of the head-mounted device on the user's head. In this way, in this embodiment, the flexible member 320 is used to fix the elastic member 310, replacing the rigid guide arc shaft or arc column or arc rib, which can prevent the problem of jamming during movement and improve the convenience and comfort of the user wearing the head-mounted device.

[0064] For example, refer to Figure 1 In one embodiment of the present invention, the pressing member 330 includes:

[0065] A pin shaft 331, one end of which is slidably connected to the housing 200, and the other end of which extends into the installation cavity through the avoidance hole 121; and

[0066] A pressing block 332, which is slidably disposed in the mounting cavity, and the other end of the flexible member 320 is connected to the pressing block 332;

[0067] When the sliding belt 100 slides out of the sliding cavity from the entrance, the pin 331 and the pressing block 332 slide synchronously and the pressing block 332 presses the elastic member 310 to cause the elastic member 310 to be compressed and deformed to generate elastic force.

[0068] Specifically, the pressing member 330 includes a pin 331 and a pressing block 332. One end of the pin 331 is slidably connected to the housing 200, and the other end of the pin 331 extends into the installation cavity through the avoidance hole 121 and is connected to the pressing block 332. The pressing block 332 is slidably arranged in the installation cavity and abuts against the end of the elastic member 310. It can be understood that the elastic member 310 has a first end and a second end relative to each other in the sliding direction of the sliding belt 100, one end of the flexible member 320 extends from the first end of the elastic member 310 and is fixedly connected to the housing 200, the other end of the flexible member 320 extends from the second end of the elastic member 310 and is fixedly connected to the pressing block 332, and the pressing block 332 is arranged on the side of the second end of the elastic member 310 away from the first end of the elastic member 310 and abuts against the second end of the elastic member 310. Thus, when the sliding belt 100 is slid, the elastic member 310 can be compressed by folding or overlapping the flexible member 320 and cooperating with the pressing block 332, so that the elastic member 310 is deformed to generate elastic force, thereby realizing the opening or tightening of the strap, and improving the convenience and comfort of wearing the head-mounted device. As an optional method, a socket is provided on the pressing block 332, and one end of the pin 331 close to the pressing block 332 is inserted into the socket, and the pin 331 and the pressing block 332 are fixed by the interference fit between the pin 331 and the socket, which can reduce the complexity of fixing the pin 331 and the pressing block 332 and improve the assembly efficiency.

[0069] For example, refer to Figure 7 In one embodiment of the present invention, a mounting groove 111 is provided in the mounting cavity, the elastic member 310 is provided in the mounting groove 111, and the pressing block 332 is slidably provided in the mounting groove 111. In this way, the mounting groove 111 can be used to limit the elastic member 310 to prevent the elastic member 310 from deforming along its radial direction, thereby improving the deformation effect of the elastic member 310 in the sliding direction of the sliding belt 100, which is conducive to the opening or tightening of the strap. On the other hand, the pressing block 332 can also be limited by the mounting groove 111, so that the pressing block 332 can abut against the end of the elastic member 310, thereby cooperating with the flexible member 320 to achieve compression of the elastic member 310.

[0070] For example, refer to Figure 1 , Figure 3 , Figure 4 as well as Figure 5 In one embodiment of the present invention, the sliding belt 100 includes a belt body 110 and a cover body 120 that are detachably connected. The belt body 110 and the cover body 120 are buckled together to form a mounting cavity. The avoidance hole 121 is provided in the cover body 120, and the mounting groove 111 is provided in the belt body 110. In this way, it is convenient to disassemble and assemble the elastic member 310 and the flexible member 320, and improve the convenience of repairing or replacing the elastic member 310 and the flexible member 320. In one embodiment, the belt body 110 and the cover body 120 can be connected by bolts or by snap-fits, which is not limited here.

[0071] For example, refer to Figure 1 and Figure 2 In one embodiment of the present invention, the strap tension adjustment device further includes a gear 400, and the sliding belt 100 is provided with teeth meshing with the gear 400. In this way, the gear 400 can be rotated to drive the sliding belt 100 to slide, thereby improving the convenience of user operation. In one embodiment, an elastic member 310, a flexible member 320 and a pressing member 330 are provided at one end of the sliding belt 100, and teeth are provided at the other end of the sliding belt 100, thereby improving the convenience of arranging each component and ensuring the structural strength of the sliding belt 100. Of course, in other embodiments, the elastic member 310, the flexible member 320, the pressing member 330 and the teeth can also be arranged simultaneously in the extension direction of the sliding belt 100, which is not limited here.

[0072] For example, in one embodiment of the present invention, two sliding belts 100 are provided, and each sliding belt 100 is provided with a housing 200 and an elastic component 300; the two sliding belts 100 are respectively engaged with the gear 400 to move toward or away from each other so that the overlapping length of the two sliding belts 100 is adjustable. Specifically, by providing two sliding belts 100, the straps can be adjusted on both sides of the user's head at the same time, thereby improving the efficiency of strap adjustment.

[0073] For example, referring to FIG. Figure 1 , Figure 3 , Figure 4 as well as Figure 5In one embodiment of the present invention, the housing 200 includes an upper shell 210 and a lower shell 220 that are detachably connected, and the upper shell 210 and the lower shell 220 are buckled together to form a sliding cavity; wherein one of the upper shell 210 and the lower shell 220 is slidably connected to the pressing member 330, and the other of the upper shell 210 and the lower shell 220 is connected to the flexible member 320. Specifically, the housing 200 includes an upper shell 210 and a lower shell 220, and the upper shell 210 and the lower shell 220 are detachably connected, for example, a bolt or a clamping connection can be used. In one embodiment, the pressing member 330 is slidably connected to the upper shell 210, and the flexible member 320 is fixedly connected to the lower shell 220; or, the pressing member 330 is slidably connected to the lower shell 220, and the flexible member 320 is fixedly connected to the upper shell 210, which is not limited here.

[0074] For example, in one embodiment of the present invention, both the upper shell 210 and the lower shell 220 are fishbone structures. Thus, through the design of the fishbone structure, the upper shell 210 and the lower shell 220 have a predetermined elasticity, and when the sliding belt 100 slides, the upper shell 210 and the lower shell 220 can be adaptively deformed synchronously to prevent the material from being squeezed and unable to deform, thereby reducing the adverse effects on the integrated design of the functional elements.

[0075] For example, refer to Figures 1 to 5 In one embodiment of the present invention, the strap tension adjustment device further includes a decorative cover 500, which is sleeved on the outside of the housing 200. In this way, on the one hand, the housing 200 and other components inside the decorative cover 500 can be protected to prevent damage to the components, and on the other hand, the aesthetics of the overall structure can be improved. In one embodiment, the decorative cover 500 is made of polyurethane, which is light, wear-resistant, aging-resistant, high in hardness, and elastic, and can reduce the overall weight of the structure and extend its service life.
