[0046] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. 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.

[0047] Reference is made below Figures 1 - 13 to describe the adjusting device 100 according to an embodiment of the present invention, where the adjusting device 100 can be applied to the head-mounted device 1000 to adjust the size of the wearing space of the head-mounted device 1000. Of course, it can be understood that the adjusting device 100 can also be applied to any device that needs to adjust the size of the wearing space. It should be noted that, for the sake of convenience of description, in the following description, the adjusting device 100 is taken as an example of being applied to the head-mounted device 1000, and it should not be construed as a limitation to the present application.

[0048] In combination with Figure 2 、 Figure 5 、 Figure 9 and Figure 12 , the adjusting device 100 according to the present invention includes: two adjusting straps 110, a driving gear 120, a switching member 130, and an adjusting member 140. Among them, the two adjusting straps 110 can be installed on the main body of the head-mounted device 1000, and the adjusting device 100 and the main body define the wearing space of the head-mounted device. Each adjusting strap 110 is provided with a mating rack 111, the driving gear 120 meshes with the mating racks 111 of the two adjusting straps 110 respectively, the switching member 130 is configured to be switchable between a first state and a second state, in the first state the switching member 130 meshes with the driving gear 120, and in the second state the switching member 130 disengages from the driving gear 120.

[0049] The adjusting member 140 cooperates with the switching member 130 to drive the switching member 130 to rotate synchronously, and the switching member 130 can move relative to the adjusting member 140 to switch between the first state and the second state.

[0050] Specifically, referring to Figure 2 、 Figure 9 and Figure 12 , a part of the two adjusting straps 110 are stacked, and the mating racks 111 on the two adjusting straps 110 are arranged oppositely. The driving gear 120 passes through the two adjusting straps 110, and the driving gear 120 meshes with the mating racks 111 on the two adjusting straps 110, and the lengths of the two adjusting straps 110 are adjusted through the transmission cooperation of the gear and the rack.

[0051] Further in combination withFigure 9 and Figure 12 , the switching member 130 can move relative to the driving gear 120 so that the switching member 130 can selectively cooperate with the driving gear 120, and when the adjusting member 140 rotates, it can drive the switching member 130 to rotate synchronously.

[0052] When the switching member 130 is in the first state, the switching member 130 meshes and cooperates with the driving gear 120. By driving the adjusting member 140 to rotate, the switching member 130 can be driven to rotate. The switching member 130 can drive the driving gear 120 to rotate, and the driving gear 120 drives the two adjusting belts 110 to move, driving the two adjusting belts 100 to expand and contract, so as to finely adjust the lengths of the two adjusting belts 110 by driving the adjusting member 140.

[0053] When the switching member 130 is in the second state, the switching member 130 is disengaged from the driving gear 120, and the lengths of the two adjusting belts 110 cannot be adjusted by driving the adjusting member 140. At the same time, since the driving gear 120 only meshes with the mating rack 111, the wearing space can be adjusted by directly pulling the adjusting belt 110 to achieve the purpose of rapid adjustment.

[0054] In the related art, the adjusting device usually has a knob adjusting mechanism to adjust the length of the adjusting belt, resulting in low adjustment efficiency when the user adjusts the length of the adjusting belt, which affects the user experience.

[0055] In this application, by setting the switching member 130, the adjusting method of the adjusting device 100 can be switched, so that the adjusting device 100 can not only finely adjust the length of the adjusting belt 110, but also quickly adjust the adjusting belt 110, improving the adjustment efficiency of the adjusting device 100 and enhancing the user experience.

[0056] According to the adjusting device 100 of the present invention, by setting the switching member 130, the switching member 130 can selectively mesh and cooperate with the driving gear 120, so that the adjusting device 100 can have two adjusting methods, that is, the adjusting device 100 can not only finely adjust the length of the adjusting belt 110, but also quickly adjust the length of the adjusting belt 110, improving the adjustment efficiency of the adjusting device 100, and the two adjusting methods can be switched, enhancing the user experience.

[0057] Combined with Figure 5 、 Figure 9 and Figure 12, in some embodiments of the present invention, the adjusting member 140 and the adjusting belt 110 are spaced apart in the thickness direction of the adjusting device 100. The adjusting member 140 is provided with a hole structure, and the switching member 130 can pass through the adjusting member 140 through the hole structure. The switching member 130 and the driving gear 120 are oppositely arranged in the thickness direction of the adjusting device 100. The switching member 130 can move relative to the adjusting member 140 and the driving gear 120. When the switching member 130 is in the first state, the switching member 130 is engaged and cooperated with the driving gear 120.

[0058] Further, when it is necessary to switch the switching member 130 from the first state to the second state, the switching member 130 is driven to move in a direction close to the adjusting belt 110, and the switching member 130 is disengaged from the driving gear 120, and the switching member 130 is in the second state. When it is necessary to switch the switching member 130 from the second state to the first state, the switching member 130 is driven to move in the direction of the adjusting member 140, and the switching member 130 is engaged and cooperated with the driving gear 120, and the switching member 130 is in the first state.

[0059] Combined with Figure 6 , Figure 9 and Figure 12 , in some embodiments of the present invention, a sunk platform 135 is formed at one end of the switching member 130 away from the adjusting belt 110, and a convex platform 144 is formed on the adjusting member 140. The convex platform 144 extends from the hole structure in the radial direction towards the central axis of the hole structure. The convex platform 144 can be in abutting cooperation with the sunk platform 135 to limit the switching member 130 in the thickness direction and prevent the switching member 130 from coming out.

[0060] Combined with Figure 2 , Figure 9 and Figure 12 , in some embodiments of the present invention, the adjusting device 100 further includes a reset member 150. The reset member 150 is respectively connected to the driving gear 120 and the switching member 130. The reset member 150 applies a force towards the switching member 130, and the force makes the switching member 130 have a tendency to switch to the first state.

[0061] Specifically, the reset member 150 can be arranged between the driving gear 120 and the switching member 130. When an external force is applied to make the switching member 130 in the second state, the switching member 130 compresses the reset member 150. At this time, the reset member 150 has elastic potential energy. When the switching member 130 is released, the elastic potential energy of the reset member 150 is released. When the reset member 150 returns to its original length, it drives the switching member 130 to reset, so that the switching member 130 switches from the second state to the first state.

[0062] Combined with Figure 2 and Figure 6, in some embodiments of the present invention, the reset member 150 is a spring. A fitting cavity 131 is provided inside the switching member 130, and one end of the spring extends into the fitting cavity 131 to abut against the switching member 130. Thus, by providing the fitting cavity 131, one end of the spring extends into the fitting cavity 131, which can reduce the volume of the adjusting device 100 and facilitate the installation of the spring.

[0063] Specifically, a fitting cavity 131 extending along the thickness direction of the adjusting device 100 is provided inside the switching member 130. One end of the spring is disposed in the fitting cavity 131 to abut against the switching member 130 in a mating manner, and the other end of the spring abuts against the driving gear 120 in a mating manner. When the switching member 130 switches from the first state to the second state, the switching member 130 compresses the spring. When the switching member 130 is released, the spring drives the switching member 130 to reset, so that the switching member 130 switches from the second state to the first state.

[0064] In some embodiments of the present invention, such as Figure 9 and Figure 12 shown in the embodiments, positioning posts 132 may be provided in the fitting cavity 131. The extending direction of the positioning posts 132 is the same as the extending direction of the fitting cavity 131. The end of the spring may be fixed on the positioning posts 132 to limit the spring, improve the connection reliability of the spring, reduce the possibility of the spring being bent, and ensure the driving effect of the spring on the switching member 130.

[0065] As Figure 6 shown, in some embodiments of the present invention, first clutch teeth 133 and second clutch teeth 134 are provided at intervals on the outer peripheral wall of the switching member 130. As Figure 7 shown, the driving gear 120 includes an internal gear ring 121. The first clutch teeth 133 mesh with or disengage from the internal gear ring 121, and the second clutch teeth 134 mesh with the adjusting member 140.

[0066] Specifically, in combination with Figure 9 and Figure 12 , the first clutch teeth 133 and the second clutch teeth 134 are spaced apart in the extending direction of the switching member 130. The first clutch teeth 133 are provided at one end of the switching member 130 close to the driving gear 120. An internal gear ring 121 is provided at one end of the driving gear 120 close to the switching member 130. When the switching member 130 is in the first state, the first clutch teeth 133 mesh with the internal gear ring 121 in a mating manner, and fine adjustment of the adjusting belt 110 can be achieved by driving the adjusting member 140.

[0067] When it is necessary to switch the switching member 130 from the first state to the second state, the switching member 130 is driven to move towards the adjusting belt 110. The first engaging tooth 133 disengages from the internal gear ring 121, and the internal gear ring 121 is disposed opposite to the intermediate region between the first engaging tooth 133 and the second engaging tooth 134, so that the switching member 130 is in the second state. At this time, the length of the adjusting belt 110 can be quickly adjusted by manually driving the adjusting belt 110, improving the adjustment efficiency of the adjusting device 100. Thus, by providing the spaced-apart first engaging tooth 133 and the second engaging tooth 134 on the outer peripheral wall of the switching member 130, the processing of the switching member 130 is facilitated, and the assembly of the switching member 130 with the driving gear 120 and the adjusting member 140 is simple. Moreover, when the switching member 130 is in the second state, a part of the switching member 130 is still located inside the internal gear ring 121, without the risk of being unable to continue to cooperate after detachment.

[0068] Of course, it can be understood that the cooperation structure between the switching member 130 and the driving gear 120 is not limited to this. For example, an internal gear ring 121 can also be provided inside the switching member 130, and external engaging teeth are provided on the outer peripheral wall of the driving gear 120 to achieve the meshing cooperation or disengagement of the switching member 130 and the driving gear 120, as long as the switching of the switching member 130 between the first state and the second state can be achieved.

[0069] Further, after the rapid adjustment of the adjusting belt 110 is completed, the switching member 130 is released, and the elastic force of the reset member 150 drives the switching member 130 to reset. The first engaging tooth 133 engages with the internal gear ring 121, and the switching member 130 switches from the second state to the first state.

[0070] In addition, a rack engaging structure is provided at one end of the driving gear 120 away from the switching member 130. The rack engaging structure can be configured as an engaging tooth, and the rack engaging structure engages with the engaging rack 111 of the adjusting belt 110 to drive the adjusting belt 110 to move towards or away from each other through the gear-rack transmission, thereby adjusting the length of the adjusting belt 110. Among them, the number of teeth of the rack engaging structure is different from the number of teeth of the internal gear ring 121, so that the transmission ratios when the switching member 130 and the engaging rack 111 are respectively engaged with the driving gear 120 are different, so as to change the transmission efficiency.

[0071] Combined with Figure 9 and Figure 12 , in some embodiments of the present invention, the adjusting device 100 further includes a housing 160. The adjusting member 140 is rotatably disposed in the housing 160, and the adjusting member 140 is provided with an anti-detachment member 141, and the anti-detachment member 141 is adapted to cooperate with the housing 160 to prevent the adjusting member 140 from falling off.

[0072] Specifically, as Figure 8As shown, an installation groove 161 is provided on the housing 160. The adjusting member 140 is assembled on the housing 160 through the installation groove 161. The adjusting member 140 can rotate within the installation groove 161 so that the adjusting member 140 can rotate relative to the housing 160.

[0073] Furthermore, the anti - detachment member 141 can be in limiting cooperation with the housing 160 to limit the adjusting member 140 in the thickness direction of the adjusting device 100, so that the adjusting member 140 can be stably connected to the housing 160, preventing the adjusting member 140 from falling off the housing 160 and ensuring the assembly reliability between the adjusting member 140 and the housing 160.

[0074] Combined with Figure 11 and Figure 13 , in some embodiments of the present invention, the anti - detachment member 141 is formed as a hook, and the hook is hooked on the housing 160.

[0075] Specifically, the hook is in snap - fit with the housing 160 to limit the adjusting member 140 and prevent the adjusting member 140 from falling off the housing 160, ensuring the assembly reliability between the adjusting member 140 and the housing 160. Among them, the hook can be arranged on the radial outer side of the adjusting member 140, and a mating groove 164 adapted to the hook can be provided on the housing 160. The hook is in limiting cooperation with the mating groove 164 so that the hook can be hooked on the housing 160.

[0076] Optionally, multiple hooks can be provided. The multiple hooks are all hooked on the housing 160 to further improve the assembly reliability between the adjusting member 140 and the housing 160 and prevent the adjusting member 140 from shaking or disengaging. Multiple mating grooves 164 can be provided on the housing 160. The multiple mating grooves 164 are arranged in one - to - one correspondence with the hooks to achieve the limiting cooperation between the hook and the mating groove 164; the mating groove 164 can also be configured to extend along the arrangement direction of the multiple hooks, and the multiple hooks can all be in limiting cooperation with the mating groove 164 to achieve the limiting cooperation between the hook and the mating groove 164. Of course, it can be understood that as long as the hook can be hooked on the housing 160, the number of hooks and the arrangement form of the mating grooves 164 are not specifically limited herein.

[0077] In some other embodiments of the present invention, the anti - detachment member 141 is provided on the housing 160, and a mating structure for cooperating with the anti - detachment member 141 can be provided on the adjusting member 140. The anti - detachment member 141 is in limiting cooperation with the mating structure to limit the adjusting member 140. The technical effects achieved by this structural setting are the same as those achieved by the above - mentioned structure, and will not be elaborated one by one here.

[0078] Combined with Figure 5 、 Figure 9 and Figure 12, in some embodiments of the present invention, the adjusting member 140 includes: a rotary knob 142 and a mating member 143. The mating member 143 is fixed to the rotary knob 142. The mating member 143 is provided with a through hole 1432. The switching member 130 passes through the through hole 1432 and meshes with the inner wall of the through hole 1432.

[0079] Specifically, the mating member 143 is fixed on the surface of the rotary knob 142 opposite to the adjusting belt 110. The switching member 130 passes through the through hole 1432. The sunk platform 135 can be in abutting cooperation with the mating member 143 to limit the distance that the switching member 130 moves in the thickness direction of the adjusting device 100 and prevent the switching member 130 from pressing against other components inside the adjusting device 100.

[0080] Referring to Figure 10 , clutch teeth can be provided on the inner wall of the through hole 1432. The second clutch teeth 134 can mesh and cooperate with the inner wall of the through hole 1432. By driving the rotary knob 142, the mating member 143 can be driven to rotate. The mating member 143 meshes and cooperates with the switching member 130, so that the mating member 143 can drive the switching member 130 to rotate.

[0081] Combined with Figure 2 , Figure 4 and Figure 8 , in some embodiments of the present invention, the adjusting device 100 further includes a housing 160. The adjusting member 140 is rotatably provided in the housing 160. The outer peripheral wall of the mating member 143 is provided with a first mating portion 1431. The housing 160 is provided with a second mating portion 165. When the adjusting member 140 rotates towards the first direction, the first mating portion 1431 cooperates with the second mating portion 165 to prevent the adjusting member 140 from rotating in the reverse direction. When the adjusting member 140 rotates towards the second direction, the first mating portion 1431 is adapted to disengage from the second mating portion 165. The first direction and the second direction are opposite.

[0082] Specifically, as Figure 8 shown, an installation groove 161 is provided on the housing 160. The adjusting member 140 is assembled on the housing 160 through the installation groove 161. The adjusting member 140 can rotate in the installation groove 161 so that the adjusting member 140 can rotate relative to the housing 160.

[0083] Furthermore, the first mating portion 1431 and the second mating portion 165 are oppositely arranged, and the first mating portion 1431 can selectively cooperate with the second mating portion 165. When the adjusting member 140 is driven to rotate towards the first direction, the first mating portion 1431 cooperates with the second mating portion 165. The second mating portion 165 can limit the rotation direction of the first mating portion 1431 and prevent the first mating portion 1431 from rotating in the reverse direction, thereby preventing the adjusting member 140 from rotating in the reverse direction.

[0084] Meanwhile, when the switching member 130 is in the first state, the first clutch tooth 133 meshes with the internal gear ring 121. By driving the rotation knob 142 to rotate, the length of the strap can be adjusted. The cooperation between the first engaging portion 1431 and the second engaging portion 165 can prevent the adjusting member 140 from rotating in the reverse direction, realizing the locking of the driving gear 120 and the adjusting belt 110, and preventing interference with the movement of the adjusting belt 110 caused by touching the adjusting belt 110.

[0085] When the adjusting member 140 rotates in the second direction, the acting force applied to the adjusting member 140 and the damping force generated inside the adjusting device 100, etc. will generate an acting force on the first engaging portion 1431, causing the first engaging portion 1431 to disengage from the second engaging portion 165, and the adjusting member 140 can rotate in the reverse direction. It can be understood that the acting force required to drive the adjusting member 140 to rotate in the second direction is greater than the acting force required to drive the adjusting member 140 to rotate in the first direction, so as to ensure self-locking and reduce the risk of mis-triggering.

[0086] Among them, the adjustment effects of the adjusting member 140 rotating in the first direction and the adjusting member 140 rotating in the second direction on the adjusting belt 110 are different. When the adjusting member 140 rotates in the first direction, it can be configured to reduce the wearing length between the two adjusting belts 110 (that is, reduce the wearing space). When the adjusting member 140 rotates in the second direction, it can be configured to increase the wearing length between the two adjusting belts 110 (that is, increase the wearing space). Of course, it can be understood that the technical effects achieved by rotating the adjusting member 140 in the first direction and in the second direction can also be set in reverse, which is not specifically limited here.

[0087] Combined with Figure 4 and Figure 8 , in some embodiments of the present invention, the first engaging portion 1431 is a pawl provided on the outer peripheral wall of the engaging member 143, and the second engaging portion 165 is a ratchet wheel.

[0088] Specifically, the pawl is arranged on the radial inner side of the ratchet wheel, and the pawl can selectively cooperate with the inner side wall of the ratchet wheel. When driving the adjusting member 140 to rotate in the first direction, the pawl cooperates with the inner side wall of the ratchet wheel, and the ratchet wheel can prevent the pawl from rotating in the reverse direction, thereby preventing the adjusting member 140 from rotating in the reverse direction. When the adjusting member 140 rotates in the second direction, the pawl is disengaged from the ratchet wheel, and the adjusting member 140 can rotate in the reverse direction.

[0089] Combined with Figure 3 and Figure 5 , in some embodiments of the present invention, the rotation knob 142 is provided with a positioning groove 1421, a part of the pawl extends into the positioning groove 1421, and a pushing protrusion 1422 that abuts against the pawl is provided on the inner wall of the positioning groove 1421.

[0090] Specifically, a positioning groove 1421 with an extending direction the same as that of the pawl is provided on the rotary knob 142, and the positioning groove 1421 is open on one side close to the through hole 1432. A part of the pawl is arranged in the positioning groove 1421, and a pushing protrusion 1422 is arranged on the side wall surface of the positioning groove 1421 opposite to the through hole 1432. When the adjusting member 140 rotates in the second direction, the pushing protrusion 1422 can press against the pawl, causing the pawl to deform. The pushing protrusion 1422 and the damping force generated inside the adjusting device 100 act together to drive the pawl to disengage from the ratchet wheel, so that the adjusting member 140 can rotate in the second direction, thereby increasing or decreasing the length of the adjusting belt 110.

[0091] Optionally, a plurality of pushing protrusions 1422 can be provided. The plurality of pushing protrusions 1422 can ensure the pressing effect on the pawl. The specific number of the pushing protrusions 1422 can be set in combination with the length of the positioning groove 1421, and no specific limitation is made here.

[0092] The adjustment method and transmission process of the adjusting device 100 according to the embodiment of the present invention will be briefly described below.

[0093] Combined with Figure 9 and Figure 11 When the switching member 130 is in the first state, the adjusting member 140 is driven to rotate. The adjusting member 140 is engaged with the switching member 130 to drive the switching member 130 to rotate. The switching member 130 is engaged with the driving gear 120 to drive the driving gear 120 to rotate. The driving gear 120 is engaged with the engaging racks 111 of the two adjusting belts 110, so that the driving gear 120 can drive the two adjusting belts 110 to move towards or away from each other through the engaging racks 111, so as to realize fine adjustment of the length of the adjusting belt 110.

[0094] Combined with Figure 12 and Figure 13 When the length of the adjusting belt 110 needs to be quickly adjusted, the switching member 130 needs to be switched to the second state, and the switching member 130 is driven to move towards the direction close to the adjusting belt 110, so that the switching member 130 is disengaged from the driving gear 120. The lengths of the two adjusting belts 110 cannot be adjusted by driving the adjusting member 140. At this time, the adjusting belt 110 can be manually driven to realize the quick adjustment of the adjusting belt 110.

[0095] After the quick adjustment of the adjusting belt 110 is completed, the switching member 130 is released, and the elastic force of the reset member 150 drives the switching member 130 to reset. The first clutch tooth 133 is engaged with the internal gear ring 121, and the switching member 130 is switched from the second state to the first state.

[0096] Combined with Figure 1 and Figure 2, the head-mounted device 1000 according to the present invention includes the above-mentioned adjusting device 100. Since the head-mounted device 1000 is provided with the above-mentioned adjusting device 100, the head-mounted device 1000 can not only achieve fine adjustment of the length of the adjusting band 110, but also achieve rapid adjustment of the length of the adjusting band 110, improve the adjustment efficiency of the adjusting device 100, and the two adjustment methods can be switched to enhance the user experience.

[0097] The head-mounted device 1000 of the present application further includes a battery assembly 1002 and a battery compartment 1001. One of the two adjusting bands 110 is configured to be fixed to the battery compartment 1001, and the other of the two adjusting bands 110 is configured to be movable relative to the battery compartment 1001. When the switching member 130 is in the second state, the size of the wearing space can be adjusted by pulling the battery compartment 1001, so as to achieve the purpose of rapid adjustment.

[0098] Furthermore, the battery assembly 1002 is disposed in the battery compartment 1001. The battery assembly 1002 can supply electrical energy to the head-mounted device 1000. The battery compartment 1001 can also be used to assemble the adjusting device 100. Among them, the housing 160 can be snap-fitted with the battery compartment 1001 to shield the internal structure of the battery compartment 1001.
