[0045] The following referenceFigures 1 - 13 Describe the adjusting device 100 according to an embodiment of the present invention. Among them, 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 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 of this application.

[0046] Combined with Figure 2 、 Figure 3 、 Figure 8 And Figure 11 According to an embodiment of the present invention, the adjusting device 100 includes: a housing 110, two adjusting belts 120, a driving gear 130, and an adjusting member 140. Among them, the two adjusting belts 120 can both 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. The two adjusting belts 120 are respectively movably arranged in the housing 110, each adjusting belt 120 is provided with a mating rack 121, the driving gear 130 is arranged in the housing 110 and meshes with the mating racks 121 of the two adjusting belts 120 respectively, the adjusting member 140 is provided with an engaging portion 141, the adjusting member 140 is rotatably arranged in the housing 110, and the adjusting member 140 is movably arranged in the housing 110 to switch between a first state and a second state. In the first state, the engaging portion 141 meshes with the driving gear 130, and in the second state, the engaging portion 141 is separated from the driving gear 130.

[0047] Specifically, combined with Figure 2 And Figure 8 A part of the two adjusting belts 120 is stacked, and at least part of the mating racks 121 of the two adjusting belts 120 are relatively arranged in the thickness direction of the adjusting device 100. The driving gear 130 passes through the adjusting belts 120, and the driving gear 130 meshes and cooperates with the mating racks 121 of the two adjusting belts 120 respectively. By driving the driving gear 130, the two adjusting belts 120 move towards or away from each other to adjust the lengths of the two adjusting belts 120.

[0048] Furthermore, the engaging portion 141 is arranged on one side of the adjusting member 140 facing the adjusting belt 120. The engaging portion 141 is used to mesh and cooperate with the driving gear 130. The adjusting member 140 can move relative to the driving gear 130 so that the engaging portion 141 can selectively mesh and cooperate with the driving gear 130. When the engaging portion 141 meshes and cooperates with the driving gear 130, the adjusting member 140 can drive the driving gear 130 to rotate when it rotates.

[0049] Combined with Figure 3 And Figure 8, when the adjusting member 140 is in the first state, the engaging portion 141 is engaged with the driving gear 130. By rotating the adjusting member 140, the driving gear 130 can be driven to rotate. The driving gear 130 is engaged with the mating rack 121 to drive the mating rack 121 to move, thereby driving the two adjusting belts 120 to expand and contract. Thus, the fine adjustment of the lengths of the two adjusting belts 120 can be achieved by driving the adjusting member 140.

[0050] Combined with Figure 3 and Figure 11 , when the adjusting member 140 is in the second state, the engaging portion 141 is disengaged from the driving gear 130, and the adjusting member 140 cannot transmit the motion to the driving gear 130. At the same time, since the driving gear 130 is only engaged with the mating rack 121, the wearing space can be adjusted by directly pulling the adjusting belt 120, achieving the purpose of quick adjustment.

[0051] In the related art, the adjusting device usually has a knob adjusting mechanism to adjust the length of the adjusting belt. However, the adjusting speed of the knob adjusting mechanism in the related art is slow, resulting in low adjusting efficiency when the user adjusts the length of the adjusting belt, affecting the user experience.

[0052] In this application, by providing the adjusting member 140, the adjusting method of the adjusting device 100 can be switched, so that the adjusting device 100 can not only achieve fine adjustment of the length of the adjusting belt 120, but also achieve quick adjustment of the length of the adjusting belt 120, improving the adjusting efficiency of the adjusting device 100 and enhancing the user experience.

[0053] According to the adjusting device 100 of the present invention, by setting the adjusting member 140 to be selectively engaged with the driving gear 130, the adjusting device 100 can have two adjusting methods, that is, the adjusting device 100 can not only achieve fine adjustment of the length of the adjusting belt 120, but also achieve quick adjustment of the length of the adjusting belt 120, improving the adjusting efficiency of the adjusting device 100, and the two adjusting methods can be switched, enhancing the user experience.

[0054] Combined with Figure 3 , Figure 7 and Figure 8 , in some embodiments of the present invention, the engaging portion 141 is formed as an internal gear ring, and the driving gear 130 includes a first clutch portion 131. In the first state, the first clutch portion 131 extends into the internal gear ring and meshes with it.

[0055] Specifically, combined with Figure 8 and Figure 10, the first clutch part 131 is arranged at one end of the driving gear 130 away from the adjusting belt 120, and the internal gear ring can be engaged or disengaged with the first clutch part 131. When the adjusting member 140 is in the first state, the first clutch part 131 extends into the internal gear ring to be engaged with the internal gear ring. The driving gear 130 is respectively engaged with the adjusting member 140 and the mating rack 121. By driving the adjusting member 140 to rotate, the driving gear 130 rotates, and the driving gear 130 drives the mating rack 121 to move, so that the adjusting belt 120 moves towards or away from each other, thereby realizing fine adjustment of the length of the adjusting belt 120.

[0056] When it is necessary to drive the adjusting member 140 to switch from the first state to the second state, the adjusting member 140 is moved in a direction away from the adjusting belt 120, so that the internal gear ring is disengaged from the first clutch part 131. As Figure 11 and Figure 13 shown, when the adjusting member 140 is in the second state, the adjusting member 140 cannot transmit the motion to the driving gear 130, and the driving gear 130 is only engaged with the mating rack 121. Therefore, the wearing space can be adjusted by directly pulling the adjusting belt 120 to achieve the purpose of quick adjustment.

[0057] Combined with Figure 7 , Figure 8 and Figure 11 , in some embodiments of the present invention, the driving gear 130 further includes a second clutch part 132, the second clutch part 132 is engaged with the mating rack 121, and the number of teeth of the first clutch part 131 and the second clutch part 132 is different.

[0058] Specifically, the second clutch part 132 is arranged at one end of the driving gear 130 away from the first clutch part 131. The second mating part 143 is used for engaging with the mating rack 121. The driving gear 130 drives the mating rack 121 to move through the second mating part 143. The number of teeth of the first clutch part 131 and the second clutch part 132 is different, so that the transmission ratios when the adjusting member 140 and the mating rack 121 are respectively engaged with the driving gear 130 are different, so as to improve the transmission efficiency of the adjusting member 140 to the mating rack 121.

[0059] Further referring to Figure 7 , a boss 133 is arranged between the first clutch part 131 and the second clutch part 132 in the extending direction of the driving gear 130. The boss 133 can space the first clutch part 131 and the second clutch part 132 to prevent the adjusting belt 120 or the driving gear 130 from slipping during the operation of the driving gear 130 and affecting the transmission effect between the adjusting belt 120 and the engaging part 141.

[0060] Furthermore, both the first clutch portion 131 and the second clutch portion 132 are formed on the outer peripheral wall of the drive gear 130. Such a setting facilitates the machining of the drive gear 130 and the assembly of the drive gear 130 and the adjusting member 140.

[0061] Of course, it can be understood that the cooperation structure between the adjusting member 140 and the drive gear 130 is not limited to this. For example, external meshing teeth can also be provided on the outer peripheral wall of the adjusting member 140, and an internal gear ring can be provided inside the drive gear 130 to achieve meshing cooperation or disengagement cooperation between the adjusting member 140 and the drive gear 130, as long as the switching of the adjusting member 140 between the first state and the second state can be achieved.

[0062] In some embodiments of the present invention, the adjusting device 100 further includes a limiting assembly, and the limiting assembly is configured to cooperate with the housing 110 and the adjusting member 140 respectively to position the adjusting member 140 in the first state or the second state.

[0063] Specifically, the limiting assembly is used to position the adjusting member 140 in the first state or the second state, improve the cooperation reliability of the adjusting member 140, and prevent the adjustment method of the adjusting belt 120 from being switched due to the sliding of the adjusting member 140. Among them, a part of the limiting assembly can be arranged at one end of the adjusting member 140 close to the adjusting belt 120. Since one end of the adjusting member 140 close to the adjusting belt 120 is hidden inside the adjusting device 100, such a setting can hide the limiting assembly and improve the appearance consistency of the adjusting device 100.

[0064] Combined with Figure 6 、 Figure 8 and Figure 11 , in some embodiments of the present invention, an installation groove 112 is provided on the housing 110, and the adjusting member 140 is assembled on the housing 110 through the installation groove 112, and the adjusting member 140 can rotate in the installation groove 112, so that the adjusting member 140 can rotate relative to the housing 110.

[0065] Combined with Figure 3 、 Figure 5 、 Figure 6 、 Figure 8 and Figure 11 , in some embodiments of the present invention, the housing 110 is provided with a through hole 111, the meshing portion 141 is movably disposed through the through hole 111, and the limiting assembly includes an elastic protrusion 151 disposed on the adjusting member 140, and the elastic protrusion 151 is adapted to switch the abutment with the opposite surface of the part of the housing 110 provided with the through hole 111.

[0066] Specifically, the through hole 111 can be provided in the installation groove 112, and the engaging portion 141 can be selectively inserted through the through hole 111. When the adjusting member 140 is in the first state, the engaging portion 141 is inserted through the through hole 111 so that the engaging portion 141 meshes with the driving gear 130. When the adjusting member 140 is in the second state, the engaging portion 141 can be located above the through hole 111.

[0067] A stop step 113 is provided in the installation groove 112. The stop step 113 is provided on the circumferential outer side of the through hole 111 and protrudes from the surface of the housing 110 facing away from the adjusting belt 120. An elastic protrusion 151 is provided on the outer peripheral wall of the engaging portion 141, and the elastic protrusion 151 extends from the outer peripheral wall of the engaging portion 141 in the radial direction towards the outer peripheral wall of the through hole 111. When the engaging portion 141 moves within the through hole 111, the elastic protrusion 151 can be pressed and deformed by the outer peripheral wall of the through hole 111.

[0068] Combined with Figure 11 and Figure 12 When the adjusting member 140 is switched from the first state to the second state, the adjusting member 140 is driven to move away from the adjusting member 140. The engaging portion 141 is disengaged from the first clutch portion 131. The engaging portion 141 and the elastic protrusion 151 are disengaged from the through hole 111. The elastic protrusion 151 resumes deformation, and in the thickness direction of the adjusting device 100, the elastic protrusion 151 abuts against the stop step 113 to position the adjusting member 140 in the second state.

[0069] Further combined with Figure 8 and Figure 9 A stop groove 114 is provided on the outer side wall of the through hole 111. The stop groove 114 extends from the outer side wall of the through hole 111 in the radial direction towards the direction away from the central axis of the through hole 111. When the adjusting member 140 is in the first state, the elastic protrusion 151 is engaged with the stop groove 114 to position the adjusting member 140 in the first state.

[0070] Of course, it can be understood that the structure of the limiting component is not limited to this. For example, a plurality of limiting grooves can be provided on the housing 110, and elastic abutting protrusions can be provided on the adjusting member 140. The abutting protrusions are switched and engaged with the plurality of limiting grooves to position the adjusting member 140 in the first state or the second state, as long as the adjusting member 140 can be positioned in the first state or the second state.

[0071] Combined with Figure 5 and Figure 6, in some embodiments of the present invention, the adjusting member 140 is provided with a first engaging portion 142, and the housing 110 is provided with a second engaging portion 143. When the adjusting member 140 rotates in the first direction, the first engaging portion 142 cooperates with the second engaging portion 143 to prevent the adjusting member 140 from rotating in the reverse direction. When the adjusting member 140 rotates in the second direction, the first engaging portion 142 is adapted to disengage from the second engaging portion 143, and the first direction and the second direction are opposite to each other.

[0072] Specifically, the first engaging portion 142 is disposed on the outer peripheral wall of the engaging portion 141, and the second engaging portion 143 is disposed in the mounting groove 112. The first engaging portion 142 and the second engaging portion 143 are disposed opposite to each other, and the first engaging portion 142 can selectively cooperate with the second engaging portion 143. When the driving adjusting member 140 rotates in the first direction, the first engaging portion 142 cooperates with the second engaging portion 143, and the second engaging portion 143 can limit the rotation direction of the first engaging portion 142 to prevent the first engaging portion 142 from rotating in the reverse direction, thereby preventing the adjusting member 140 from rotating in the reverse direction.

[0073] Further, when the adjusting member 140 is in the first state, the driving gear 130 is respectively engaged with the adjusting member 140 and the engaging rack 121. By driving the adjusting member 140 to rotate, the length of the adjusting belt 120 is adjusted. The cooperation between the first engaging portion 142 and the second engaging portion 143 can prevent the adjusting member 140 from rotating in the reverse direction, realizing the locking of the driving gear 130 and the engaging rack 121, so that the driving gear 130 and the engaging rack 121 are linked with the adjusting member 140, and preventing interference with the movement of the adjusting belt 120 due to touching the adjusting belt 120.

[0074] 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 act on the first engaging portion 142, so that the first engaging portion 142 disengages from the second engaging portion 143, 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.

[0075] 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 120 are different. The rotation of the adjusting member 140 in the first direction can be configured to reduce the wearing length between the two adjusting belts 120 (i.e., reduce the wearing space), and the rotation of the adjusting member 140 in the second direction can be configured to increase the wearing length between the two adjusting belts 120 (i.e., increase the wearing space). Of course, it can be understood that the technical effects achieved by the adjusting member 140 rotating in the first direction and rotating in the second direction can also be set in the reverse direction, which is not specifically limited herein.

[0076] Optionally, a plurality of first engaging portions 142 may be provided. The plurality of first engaging portions 142 are spaced apart in the circumferential direction of the engaging portion 141. Providing a plurality of first engaging portions 142 can ensure the stability when the first engaging portion 142 cooperates with the second engaging portion 143, and can ensure the cooperation effect between the first engaging portion 142 and the second engaging portion 143.

[0077] In some embodiments of the present invention, the first engaging portion 142 is a pawl, and the second engaging portion 143 is a ratchet wheel.

[0078] Specifically, the pawl can selectively cooperate with the inner side wall of the ratchet wheel. When the driving adjustment member 140 rotates 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 adjustment member 140 from rotating in the reverse direction. When the adjustment member 140 rotates in the second direction, the pawl is disengaged from the ratchet wheel, and the adjustment member 140 can rotate in the reverse direction.

[0079] Combined Figures 3 - 5 , in some embodiments of the present invention, the adjustment member 140 includes a rotary knob 144 and a cooperating member 145. The cooperating member 145 is fixed to the rotary knob 144, and the cooperating member 145 is provided with an engaging portion 141 and a first engaging portion 142.

[0080] Specifically, the cooperating member 145 is fixed on the surface of the rotary knob 144 close to the adjustment belt 120. A hole structure is formed in the middle position of the cooperating member 145. The engaging portion 141 is formed on the inner side wall of the cooperating member 145. The first clutch portion 131 can extend into the cooperating member 145 to cooperate with the engaging portion 141. The first engaging portion 142 is provided on the outer side wall of the cooperating member 145, and the first engaging portion 142 can selectively cooperate with the second engaging portion 143.

[0081] Combined Figure 3 and Figure 4 , in some embodiments of the present invention, a positioning groove 1441 is provided on the rotary knob 144. A part of the pawl extends into the positioning groove 1441, and a pushing protrusion 1442 that abuts against the pawl is provided on the inner wall of the positioning groove 1441.

[0082] Specifically, a positioning groove 1441 with an extending direction the same as that of the pawl is provided on the rotary knob 144, and the positioning groove 1441 is open on the side close to the through hole 111. A part of the pawl is arranged in the positioning groove 1441, and a pushing protrusion 1442 is arranged on the side wall surface of the positioning groove 1441 opposite to the through hole 111. When the adjusting member 140 rotates in the second direction, the pushing protrusion 1442 can press against the pawl, causing the pawl to deform. The acting force generated inside the adjusting device 100 and the pushing protrusion 1442 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 120. Among them, the positioning grooves 1441 and the pawls are arranged in one-to-one correspondence.

[0083] Optionally, a plurality of pushing protrusions 1442 can be provided. The plurality of pushing protrusions 1442 can ensure the pressing effect on the pawl. The number of the pushing protrusions 1442 can be set in combination with the length of the positioning groove 1441, and no specific limitation is made here.

[0084] In some embodiments of the present invention, the adjusting device 100 further includes a anti - detachment member 160. The anti - detachment member 160 is arranged on the adjusting member 140. In the second state, the anti - detachment member 160 is adapted to abut against the housing 110 to prevent the adjusting member 140 from falling off.

[0085] Specifically, the anti - detachment member 160 is arranged on the side of the adjusting member 140 close to the adjusting belt 120. When driving the adjusting member 140 to switch from the first state to the second state, the anti - detachment member 160 moves in the direction close to the mounting groove 112. When the adjusting member 140 is in the second state, the anti - detachment member 160 abuts and cooperates with the housing 110 to limit the moving distance of the adjusting member 140 and prevent the adjusting member 140 from falling off.

[0086] Among them, the anti - detachment member 160 can be integrally formed with the adjusting member 140 for the convenience of assembling the adjusting device 100. The anti - detachment member 160 can also be separately arranged from the adjusting member 140 for the convenience of processing the anti - detachment member 160 and the adjusting member 140. As long as the anti - detachment member 160 can play the role of preventing the adjusting member 140 from falling off, its setting method is not specifically limited here.

[0087] As Figure 2 shown, in some embodiments of the present invention, the anti - detachment member 160 is a screw fixed to the adjusting member 140.

[0088] Specifically, a groove structure can be provided on the housing 110. The screw can be located in the groove structure, and the size of the groove structure is larger than the radial size of the screw. When the adjusting member 140 slides, the screw can slide in the groove structure. When the adjusting member 140 finishes switching to the second state, the screw and the groove structure abut and cooperate in its sliding direction to limit the moving distance of the adjusting member 140 and prevent the adjusting member 140 from falling off.

[0089] Combined with Figure 2 , Figure 4 , Figure 8 and Figure 11 , in some other embodiments of the present invention, the adjusting device 100 further includes a battery compartment 170. A limiting groove 171 extending towards the housing 110 can be formed on the battery compartment 170. An extension portion 146 can be provided on the side of the adjusting member 140 close to the adjusting belt 120. The extension portion 146 extends from the adjusting member 140 towards the adjusting belt 120. The extension portion 146 can pass through the driving gear 130 and extend into the limiting groove 171. A screw is installed at the end of the extension portion 146 located in the limiting groove 171, and the extension portion 146 and the screw can slide in the limiting groove 171. In the second state, the screw abuts against the side surface of the limiting groove 171 close to the housing 110 to limit the moving distance of the adjusting member 140 and prevent the adjusting member 140 from falling off.

[0090] Furthermore, the housing 110 can be snap-fitted with the battery compartment 170 to shield the internal structure of the battery compartment 170, and at the same time, it can also play a role in protecting the internal structure of the battery compartment 170.

[0091] In addition, one of the two adjusting belts 120 can be configured to be fixed to the battery compartment 170, and the other of the two adjusting belts 120 is configured to be movable relative to the battery compartment 170. When the adjusting member 140 is in the second state, by pulling the battery compartment 170, the size of the wearing space can be adjusted, so as to achieve the purpose of quick adjustment.

[0092] The following briefly describes the adjustment method and transmission process of the adjusting device 100 of the embodiment of the present invention.

[0093] The driving gear 130 is engaged with the mating rack 121. Combined with Figure 8 , Figure 9 and Figure 10 , when in the first state, at this time, the elastic protrusion 151 is snap-fitted with the stop groove 114 to fix the adjusting member 140 to the first state. The adjusting member 140 is engaged with the driving gear 130, and the adjusting member 140 drives the driving gear 130 to rotate, thereby driving the mating rack 121 to move towards or away from each other to achieve fine adjustment of the length of the adjusting belt 120.

[0094] When the length of the adjusting belt 120 needs to be quickly adjusted, it is necessary to switch the adjusting member 140 from the first state to the second state, that is, drive the adjusting member 140 to move away from the adjusting belt 120, so that the adjusting member 140 is disengaged from the driving gear 130, as Figure 11 , Figure 12 , Figure 13As shown, when the adjusting member 140 is switched to the second state, the elastic protrusion 151 abuts against the stopping step 113 to position the adjusting member 140 in the second state, preventing the adjusting member 140 from sliding and switching back to the first state again, and ensuring the mating reliability of the adjusting member 140. Meanwhile, the anti-disengagement member 160 abuts against the limiting groove 171 (groove structure) to limit the moving distance of the adjusting member 140 and prevent the adjusting member 140 from disengaging.

[0095] Since the adjusting member 140 is disengaged from the driving gear 130, the movements of the driving gear 130 and the mating rack 121 are independent of the adjusting member 140. By manually driving the adjusting belt 120, the length of the adjusting belt 120 can be quickly adjusted.

[0096] As Figure 1 shown, 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 belt 120, but also achieve quick adjustment of the length of the adjusting belt 120, improving the adjustment efficiency of the adjusting device 100, and the two adjustment methods can be switched, enhancing the user experience.

[0097] The head-mounted device 1000 of the present application further includes a battery assembly 1002. The battery assembly 1002 is disposed in the battery compartment 170, and the battery assembly 1002 can supply electrical energy to the head-mounted device 1000.
