[0025] The above strap structure has at least the following beneficial effects:
[0026] In the technical solution of the present invention, when a user needs to adjust the length of the strap, the user drives the trigger member to move towards the locking member, thereby driving the locking member to rotate and disengage from the clamping portion. Since the clamping portion on the clamping section is not blocked, the clamping section can move away from the device main body, thereby increasing the total length of the strap connecting the two ends of the device main body; or the clamping section moves towards the device main body, thereby shortening the total length of the strap connecting the two ends of the device main body. When the strap is adjusted to the required length, the locking member is re-engaged with a corresponding clamping portion, thereby increasing the stability of the strap binding. It can be seen that this solution can adjust the length of the strap according to different head circumferences, increasing the comfort of the user wearing; moreover, the strap structure proposed in the technical solution of the present invention only needs to drive the trigger member to drive the locking member to rotate to adjust the length of the strap. It can be seen that the process of adjusting the length of the strap in this solution is simple and convenient for the user to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0046] It should be noted that all directional indications (such as up, down, left, right, front, back,...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.
[0047] In the present invention, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0048] In addition, if there is a description involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.
[0049] The present invention provides a structure of a strap 200.
[0050] The head-mounted device of this solution can be a virtual reality head-mounted device, an augmented reality head-mounted device, a mixed reality head-mounted device, or a watch, etc. No specific limitation is made on the head-mounted device here.
[0051] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 andFigure 8 In an embodiment of the present invention, the strap structure is used for a head-mounted device. The head-mounted device includes a device main body 100. The strap structure includes a strap 200 and a locking device 300. At least one end of the strap 200 is provided with a clamping section 210. The clamping section 210 is provided with a plurality of clamping portions 211. The plurality of clamping portions 211 are arranged along the extending direction of the strap 200. A locking device 300 is provided corresponding to one clamping section 210. The locking device 300 includes a mounting shell, a trigger member 310 and a locking member 320. The mounting shell is used for connecting with the device main body 100. The mounting shell is provided with a mounting cavity 111. The first side wall of the mounting cavity 111 is provided with an opening 111a. The second side wall adjacent to the first side wall of the mounting cavity 111 is provided with a through hole. The clamping section 210 is movably arranged in the mounting cavity 111 through the opening 111a. The locking member 320 is rotatably arranged in the mounting cavity 111. The trigger member 310 movably passes through the through hole to movably trigger the locking member 320, so that the locking member 320 has a locking state and an unlocking state. In the locking state, the locking member 320 selectively engages with one clamping portion 211. In the unlocking state, the trigger member 310 triggers the locking member 320 to rotate, and the locking member 320 is disengaged from the clamping portion 211. The clamping section 210 can move away from the device main body 100 to adjust the total length of the strap 200 connecting the two ends of the device main body 100.
[0052] Specifically, when the user needs to adjust the length of the strap 200, the user drives the trigger member 310 to move towards the locking member 320, thereby driving the locking member 320 to rotate and disengage from the clamping portion 211. Since the clamping portions 211 on the clamping section 210 are not blocked, the clamping section 210 can move away from the device main body 100 to increase the total length of the strap body connecting the two ends of the device main body 100 by the strap 200; or the clamping section 210 moves towards the device main body 100 to shorten the total length of the strap body connecting the two ends of the device main body 100 by the strap 200. When the strap 200 is adjusted to the required length, the locking member 320 re-engages with a corresponding clamping portion 211 to increase the stability of the strap 200 binding. It can be seen that this solution can adjust the length of the strap 200 according to different head circumferences, improving the comfort of the user's wearing. Moreover, for the strap structure proposed by the technical solution of the present invention, only by driving the trigger member 310 to drive the locking member 320 to rotate can the length of the strap 200 be adjusted. It can be seen that the process of adjusting the length of the strap 200 in this solution is simple and convenient for the user to operate.
[0053] Furthermore, in this solution, the locking device 300 and the clamping section 210 are engaged in the mounting cavity 111, and the mounting shell can cover the trigger member 310, the locking member 320 and the clamping section 210, effectively solving the problem of hair pinching during the process of adjusting the length of the strap 200.
[0054] It should be noted that with reference toFigure 9 , Figure 9 It is a schematic structural diagram of the process when the clamping section 210 just penetrates into the installation cavity 111. When the clamping section 210 just penetrates into the installation cavity 111, it can drive the trigger member 310 to drive the locking member 320 to be in the unlocked state. When pushing the clamping section 210 into the installation cavity 111, this can avoid interference between the locking member 320 and the clamping section 210 penetrating into the installation cavity 111, and make it more labor-saving for the clamping section 210 to penetrate into the installation cavity 111.
[0055] In this solution, one end of the strap 200 is provided with a clamping section 210, and a locking device 300 is arranged corresponding to the clamping section 210. The other end is directly connected to the device main body 100, which can solve the problem of switching different head circumferences with one strap 200. Of course, the present invention is not limited to this. In other embodiments, clamping sections 210 can be provided at both ends of the strap 200, and a locking device 300 is arranged for one clamping section 210.
[0056] It should be noted that the trigger member 310 is exposed on the second side wall; the total length of the strap 200 connecting both ends of the device main body 100 refers to the actual length of the strap 200 used to be worn on the user's head or hand.
[0057] Among them, the second side wall is the side wall in the width direction of the strap 200, that is, the upper side wall or the lower side wall, which is convenient for the user to trigger and improves the user experience. Of course, the present invention is not limited to this. In other embodiments, the second side wall can also be configured as other side walls.
[0058] In this embodiment, the second side wall is the upper side wall.
[0059] Refer to 5 to Figure 7, optionally, a guiding convex portion 321 is provided on the side of the locking member 320 facing the triggering member 310. The height of the guiding convex portion 321 gradually increases in the rotation direction of the locking member 320. The triggering member 310 is correspondingly provided with a first guiding inclined surface 311 for the guiding convex portion 321. The first guiding inclined surface 311 acts on the guiding convex portion 321 to enable the triggering member 310 to drive the locking member 320 to rotate. In this way, during the process of the triggering member 310 moving towards the locking member 320, the first guiding inclined surface 311 will act on the guiding convex portion 321, causing the guiding convex portion 321 to gradually rotate along the first guiding inclined surface 311, so as to become disengaged from the engaging portion 211. Such a driving process is simple and does not require extra actions. Only by driving the triggering member 310 to move towards the locking member 320, the first guiding inclined surface 311 will cause the locking member 320 to rotate. Such a triggering process is simple, and the adjustment of the length of the strap 200 can be easily solved whether in a standing position or a lying position, enhancing the user experience. Of course, in other embodiments, the positions of the guiding convex portion 321 and the first guiding inclined surface 311 can be interchanged. The guiding convex portion 321 is provided on the triggering member 310, and the first guiding inclined surface 311 is provided on the locking member 320.
[0060] In other embodiments, a limiting protrusion can also be provided on the side of the locking member 320 facing the triggering member 310, and a limiting groove is correspondingly provided on the triggering member 310 for the limiting protrusion to be movably engaged therewith, so that the triggering member 310 can drive the locking member 320 to rotate. When it is necessary to drive the locking member 320 to rotate, first drive the triggering member 310 to move towards the locking member 320. When the limiting protrusion is engaged in the limiting groove, drive the triggering member 310 to rotate, thereby driving the locking member 320 to rotate to disengage from the engaging portion 211.
[0061] Optionally, the triggering member 310 includes a reset member 312 and a triggering rod 313. The triggering rod 313 movably passes through the through-hole, and the reset member 312 is sleeved on the triggering rod 313, so that the triggering rod 313 has a tendency to move away from the locking member 320. In this way, after the triggering member 310 completes triggering the locking member 320, when the acting force is withdrawn from the triggering member 310, the triggering rod 313 can be separated from the locking member 320 under the action of the reset member 312, which is beneficial to avoiding interference between the locking member 320 and the triggering rod 313 during the process of the locking member 320 resetting and re-engaging with the engaging portion 211, and hindering the locking member 320 from resetting and engaging with the engaging portion 211. Secondly, since the triggering rod 313 is automatically separated from the locking member 320 under the action of the reset member 312, there is a certain space between the locking member 320 and the triggering member 310, which is beneficial to avoiding accidental touching of the triggering member 310 by the user. Of course, the present invention is not limited thereto. In other embodiments, the triggering member 310 can also only include the triggering rod 313 without providing the reset member 312, and the triggering rod 313 is manually reset after the triggering member 310 completes triggering the locking member 320.
[0062] Furthermore, the reset member 312 is configured as a reset spring because the reset spring is inexpensive and easy to install. This can not only reduce the cost of the trigger member 310 but also improve the installation efficiency of the trigger member 310. Of course, the present invention is not limited thereto. In other embodiments, the reset member 312 can also be configured as a shrapnel.
[0063] Optionally, a limiting convex portion 313a is provided on the outer peripheral surface of the trigger rod 313, and both ends of the reset member 312 are respectively connected to the limiting convex portion 313a and the second side wall. The setting of the limiting convex portion 313a can make the installation process of the reset member 312 simpler and improve the installation efficiency. Of course, the present invention is not limited thereto. In other embodiments, the limiting convex portion 313a may not be provided on the outer peripheral surface of the trigger rod 313, and the reset member 312 may be directly connected to the trigger rod 313.
[0064] Optionally, a reset cavity 112 is provided on the second side wall. On both side walls of the reset cavity 112 in the moving direction of the trigger rod 313, a through hole is respectively provided. The limiting convex portion 313a is provided in the reset cavity 112 and slides along the cavity wall of the reset cavity 112. Both ends of the reset member 312 are respectively connected to the limiting convex portion 313a and the cavity wall of the reset cavity 112. The trigger rod 313 has two rod bodies respectively disposed on both sides of the limiting convex portion 313a, and the two rod bodies respectively pass through the two through holes. It can be understood that making the limiting convex portion 313a slide along the cavity wall of the reset cavity 112 can increase the stability of the movement of the trigger rod 313, avoid the trigger rod 313 deviating from the preset movement trajectory and being unable to trigger the locking member 320. Moreover, arranging the reset member 312 in the reset cavity 112 can protect the reset member 312 and increase the service life of the reset member 312. Of course, the present invention is not limited thereto. In other embodiments, the reset cavity 112 may not be provided, and the rod body of the trigger rod 313 moves along the depth direction of the through hole.
[0065] Refer to Figure 8 and Figure 10, optionally, the locking device 300 further includes an elastic member 322 disposed between the mounting shell and the locking member 320 to make the locking member 320 tend to move towards the locked state; it can be understood that when the trigger member 310 drives the locking member 320 to rotate, the elastic member 322 is in a compressed state. When the strap 200 is adjusted to an appropriate length, the acting force is withdrawn from the trigger member 310, and the trigger member 310 returns to the state of being separated from the locking member 320 under the action of the reset member 312. The locking member 320 rotates reversely under the action of the elastic restoring force of the elastic member 322, so as to engage with the corresponding engaging portion 211. In this way, the locking member 320 can be automatically engaged with the corresponding engaging portion 211, which increases the convenience of adjusting the strap 200. Of course, the present invention is not limited thereto. In other embodiments, the elastic member 322 may not be provided. When the strap 200 is adjusted to an appropriate length, the user then drives the trigger member 310 to rotate reversely, thereby driving the locking member 320 to rotate reversely, so as to engage with the corresponding engaging portion 211.
[0066] In this embodiment, the locking member 320 includes a rotating body 323 and a pushing end 324 protruding from the rotating body 323. The elastic member 322 is disposed between the pushing end 324 and the housing 110. Such a locking member 320 has a simple structure and is convenient for installing the elastic member 322. Of course, the present invention is not limited thereto. In other embodiments, the pushing end 324 may not be provided, and the elastic member 322 is configured as a torsion spring, so that the rotating body 323 has a tendency to engage with the engaging portion 211.
[0067] Further, the elastic member 322 may be configured as a spring or a spring sheet, and the specific type of the elastic member 322 is not limited herein.
[0068] Referring to Figure 4 and Figures 10 to 12 , optionally, the engaging portion 211 is configured as an engaging hole, and the locking member 320 further includes an engaging end protruding from the rotating body 323 for engaging with the engaging hole; such a structure is simple and convenient for engagement. Of course, the present invention is not limited thereto. In other embodiments, the engaging portion 211 may also be configured as an engaging protrusion, and a card slot is provided on the outer peripheral surface of the rotating body 323.
[0069] It should be noted that in other embodiments, the engaging portion 211 may also be configured as an engaging groove.
[0070] Referring to Figure 11 and Figure 13, wherein, the clamping end is a clamping plate 325 that extends obliquely in a direction approaching the device main body 100. In this way, when the strap 200 shortens the total length of the strap body connecting the two ends of the device main body 100, the surface of the clamping plate 325 facing the opening 111a of the installation cavity 111 is an inclined surface. In this way, in the running direction of the strap 200 when shortening the length, the strap can be unobstructed, and it can also play a role in guiding the strap 200 to tighten, and only restrict the clamping section 210 in the running direction of increasing the total length of the strap body connecting the two ends of the device main body 100 by the strap 200. In this way, it is more convenient for the user to tighten the strap 200, making the length adjustment of the strap 200 more convenient. Of course, the present invention is not limited to this. In other embodiments, the clamping end can also be perpendicular to the clamping section 210.
[0071] Refer to Figure 14 , optionally, the free end face of the clamping plate 325 is provided with a second guiding inclined surface 325a. In the direction away from the rotating body, the distance from the second guiding inclined surface 325a to the side of the clamping plate 325 facing away from the device main body 100 gradually decreases; it can be understood that the second guiding inclined surface 325a can guide the clamping plate 325 to be inserted into the clamping hole, facilitating the clamping of the clamping plate 325 and the clamping hole. Of course, the present invention is not limited to this. In other embodiments, the free end face of the clamping plate 325 can also be a flat surface.
[0072] Refer to Figure 8 , optionally, a protective shell 111b is provided in the installation cavity 111 to divide the installation cavity 111 into an installation space 111c located inside the protective shell 111b and a locking space 111d located outside the protective shell 111b. The opening 111a is communicated with the locking space 111d. The locking member 320 is arranged in the installation space 111c. The protective shell 111b is provided with an avoidance opening 111e communicating the installation space 111c and the locking space 111d. The clamping plate 325 passes through the avoidance hole to be engaged with a clamping portion 211 of the clamping section 210 movably passing through the locking space 111d. The setting of the protective shell 111b can, on the one hand, prevent the elastic member 322 from interfering with the clamping section 210, and on the other hand, can protect the locking member 320. Of course, the present invention is not limited to this. In other embodiments, the protective shell can also be not provided, and the locking member 320 and the clamping section 210 can be directly placed in the installation cavity 111.
[0073] It should be noted that the elastic member 322 is arranged between the shell wall of the protective shell and the pushing end 324.
[0074] Refer to Figure 1, optionally, the strap 200 is provided with a laterally protruding pulling part 220 for a user to hold and push or pull; it can be understood that when adjusting the length of the strap 200, the pulling part 220 of the strap 200 can be pulled, and force can be applied in the direction of shortening or increasing the length of the strap 200 to pull the strap 200. Finally, the strap 200 is automatically locked by the locking member 320, that is, when the acting force is withdrawn from the triggering member 310, the locking member 320 will engage with the clamping part 211 under the action of the elastic member 322. It can be seen that the setting of the pulling part 220 is convenient for the user to hold, making the length adjustment of the strap 200 more labor-saving, and the setting of the pulling part is convenient for the user to adjust the length with one hand, making the operation of the user more convenient. Of course, the present invention is not limited to this. In other embodiments, the pulling part 220 may not be provided.
[0075] Among them, the pulling part 220 is configured with a soft material, so as to prevent the pulling part from hurting the user when colliding with surrounding components, and increasing the wearing safety.
