Description

Technical Field

[0001] This application belongs to the technical field of shared devices, and more specifically, it relates to an automatic disassembly system for helmet linings. Background Art

[0002] With the convenience and diversification of modern transportation methods, shared electric bicycles, as a means of transportation that can be used at any time, have been widely popularized in urban areas. Among them, shared helmets, as safety devices used in conjunction with shared electric bicycles, are clearly stipulated in traffic safety regulations that electric bicycles must be used with safety helmets. Different from non-shared helmets, the design of shared helmets and their linings tries to meet the usage scenarios and conditions of shared electric bicycles.

[0003] However, there are the following technical problems in the use of existing shared helmets:

[0004] First, shared helmets are often exposed to the outdoor environment, and the foldable linings therein become dirty due to exposure. Users may choose to give up using shared electric bicycles because of the dirt, or users may choose to use electric bicycles but give up using helmets, resulting in an increased probability of electric bicycle safety accidents.

[0005] Second, as a shared device, the lining in the shared helmet is in direct contact with the user's head. The hygienic use of the lining is a safety consideration factor for users to choose shared helmets and is also the main reason for users to give up using helmets.

[0006] Therefore, in order to solve the hygienic problems of shared electric bicycle helmets and improve the user's willingness and experience of use, it is urgent to provide a device that can automatically disassemble disposable linings from helmets. Summary of the Invention

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0108] Now, the automatic helmet liner disassembly system 1000 provided by the embodiments of the present application will be described.

[0109] Among them, in the following embodiments, the central axes of the locking mechanism 202, the replaceable liner 300, the disassembly member 103, the helmet 200, and the disassembly device 100 all extend in the same direction, and the direction of this central axis is the lifting direction. The circumferential directions of the replaceable liner 300, the disassembly member 103, the helmet 200, and the disassembly device 100 are all in the same direction. Among them, the following first direction may be the radial direction or the tangential direction of the helmet 200 and the replaceable liner 300.

[0110] Please refer to Figures 1 to 17 and Figure 29 and Figure 30 As shown in, the automatic helmet liner disassembly system 1000 provided by the embodiments of the present application includes a helmet 200 and a disassembly device 100. The helmet 200 is used for detachably mounting on the disassembly device 100. The helmet 200 includes a helmet shell 201 and a locking mechanism 202. The locking mechanism 202 is provided on the inner wall of the helmet shell 201 and is used for locking or unlocking the replaceable liner 300 of the helmet 200. Among them, the locking mechanism 202 has a locking position and an unlocking position and can be switched between the two. When the locking mechanism 202 is in the locking position, the replaceable liner 300 is locked and thus fixed to the helmet 200. When the locking mechanism 202 is in the unlocking position, the replaceable liner 300 is unlocked and thus disassembled from the helmet 200.

[0111] The disassembly device 100 includes a lifting mechanism 102 and a disassembly member 103, and the disassembly member 103 has a disassembly portion 1031; when the helmet 200 is mounted on the disassembly device 100, the disassembly portion 1031 and the locking mechanism 202 are arranged opposite to each other along the lifting direction of the lifting mechanism 102. The lifting mechanism 102 can drive one of the helmet 200 and the disassembly member 103 to move up and down relative to the other, and insert the disassembly member 103 into the locking mechanism 202 along the lifting direction and drive the locking mechanism 202 to switch from the locked position to the unlocked position.

[0112] The automatic disassembly system 1000 for the inner lining 300 of the helmet 200 provided by the embodiments of the present application includes a lifting mechanism 102 and a disassembly member 103. When the helmet 200 is mounted on the disassembly device 100, the disassembly portion 1031 and the locking mechanism 202 are arranged opposite to each other along the lifting direction of the lifting mechanism 102. The lifting mechanism 102 can drive one of the helmet 200 and the disassembly member 103 to move up and down relative to the other, and insert the disassembly member 103 into the locking mechanism 202 along the lifting direction and drive the locking mechanism 202 to switch from the locked position to the unlocked position. By arranging the lifting mechanism 102 in the disassembly device 100, the lifting mechanism 102 selectively drives the helmet 200 or the disassembly member 103, and the disposable inner lining 300 can be conveniently removed from the helmet 200, which is beneficial for subsequent users to manually or automatically replace the new disposable inner lining 300.

[0113] In some embodiments, the automatic disassembly system 1000 further includes a detachable component 104 for detachably mounting the helmet 200. Moreover, the detachable component 104 is provided at the lifting end of the lifting mechanism 102, and the lifting mechanism 102 can drive the helmet 200 to move up and down relative to the disassembly member 103 through the detachable component 104.

[0114] For example, in some specific embodiments, the disassembly device 100 includes a housing 101, and the housing 101 has a disassembly opening 1011 adapted to the wearing opening 2011 of the helmet 200. At least two detachable components 104 are provided near the disassembly opening 1011, and the two detachable components 104 are arranged at intervals along the circumference of the disassembly opening 1011 or arranged in pairs along the radius of the disassembly opening 1011. The two detachable components 104 are used for detachably connecting with two detachable structures 2012 on the helmet 200, so that the helmet 200 can be detachably connected to the disassembly device 100 to complete the replacement of the inner lining 300.

[0115] The user can manually fit the shared helmet 200 onto at least two detachable components 104. Since the two detachable components 104 are arranged at intervals along the circumference of the disassembly opening 1011 or arranged in pairs along the radius of the disassembly opening 1011, the helmet 200 can be stably positioned on the disassembly device 100 along the circumference of the helmet 200.

[0116] For example, in some specific embodiments, the lifting mechanism 102 is disposed inside the housing 101, and the lifting mechanism 102 includes a lifting assembly 1021 and a driven part 1022, and is driven to extend along the circumference of the disassembly opening 1011, and the lifting direction of the driven part 1022 is perpendicular to the circumference of the disassembly opening 1011. The driven part 1022 is transmission-connected to the lifting assembly 1021, and is configured to be able to approach or move away from the disassembly opening 1011 along the lifting direction under the drive of the lifting assembly 1021. The detachable assembly 104 is disposed on the driven part 1022 on a side facing the disassembly opening 1011, and the detachable assembly 104 is used for detachably installing the helmet 200, and when the helmet 200 is installed on the detachable assembly 104, the wearing opening 2011 and the disassembly opening 1011 of the helmet 200 are coaxially arranged along the lifting direction. In this way, by driving the lifting mechanism 102 to lift the helmet 200, the helmet 200 can be reciprocated in the lifting direction. During the lifting process, the helmet 200 can be plugged into the locking mechanism 202 to complete the automatic disassembly of the liner 300.

[0117] In some embodiments, the disassembly device 100 includes two detachable components 104 and two lifting mechanisms 102, and the two detachable components 104 and the two lifting mechanisms 102 are arranged one to one; and the two lifting mechanisms 102 are arranged at intervals along the radial direction of the disassembly device 100, and the two detachable components 104 are the same or different, and the two lifting mechanisms 102 are the same or different.

[0118] By providing two detachable components 104 and two lifting mechanisms 102 , it is possible to ensure that the helmet 200 can be lifted and lowered smoothly as a whole, and then plugged into the mounting parts with high precision, thereby successfully completing the removal of the replaceable liner 300 .

[0119] In some embodiments, the disassembly device 100 includes a housing 101, the housing 101 has a disassembly opening 1011, and the disassembly opening 1011 is used to be coaxially aligned with the helmet 200. Moreover, the disassembly opening 1011, the disassembly member 103 and the lifting mechanism 102 are sequentially arranged along the lifting direction, and the lifting mechanism 102 is connected to the disassembly member 103 and can drive the disassembly member 103 to rise and fall relative to the disassembly opening 1011.

[0120] The lifting mechanism 102 of this embodiment is transmission-connected to the disassembly part 103 , and the lifting mechanism 102 drives the disassembly part 103 to rise and fall relative to the helmet 200 . Compared with the previous embodiment, this embodiment can reduce the number of lifting mechanisms 102 , and only one lifting mechanism 102 is required to meet the demand of driving the disassembly part 103 .

[0121] In some embodiments, the disassembly device 100 also includes a U-shaped frame, and the opening of the U-shaped frame is arranged opposite to the disassembly port 1011; the U-shaped frame and the lifting mechanism 102 are arranged inside the shell 101, and the disassembly part 103 is arranged in the frame of the U-shaped frame; and the two side walls of the U-shaped frame are respectively slidably connected to the shell 101, and the lifting end of the lifting mechanism 102 is connected to the bottom wall of the U-shaped frame.

[0122] In this embodiment, the characteristics of the U-shaped frame are cleverly utilized. The two side walls thereof are respectively slidably connected to the shell 101, providing a guide rail and a guiding function for the lifting mechanism 102 to drive the disassembly part 103 to lift and lower. The bottom wall thereof is used as the part connected to the lifting end of the lifting mechanism 102. The functions of the bottom wall and the side walls do not interfere with each other. In addition, the opening of the U-shaped frame is utilized. The disassembly part 1031 on the disassembly part 103 can be arranged at the opening of the U-shaped frame, so as to facilitate the insertion of the disassembly part 1031 with the locking mechanism 202 of the helmet 200.

[0123] In this embodiment, the number of the lifting mechanism 102 can be set to one, which can reduce the manufacturing cost of the disassembly device 100. The lifting mechanism 102 can be a cylinder mechanism, a screw drive mechanism or other mechanism that can achieve linear drive. In this embodiment, since the lifting mechanism 102 is arranged inside the housing 101, it is always connected to the disassembly member 103, and does not need to be connected to the helmet 200 that requires high-frequency disassembly and assembly, so the probability of damage to the lifting mechanism 102 can be reduced.

[0124] In some embodiments, the disassembly device 100 has a disassembly opening 1011, and the disassembly opening 1011 is used to be coaxially aligned with the helmet 200. Moreover, the disassembly opening 1011 and the disassembly member 103 are sequentially arranged along the lifting direction, the disassembly member 103 and the lifting mechanism 102 are sequentially arranged along a direction perpendicular to the lifting direction, and the lifting mechanism 102 is connected to the disassembly member 103 and can drive the disassembly member 103 to rise and fall relative to the disassembly opening 1011.

[0125] The lifting mechanism 102 of this embodiment is transmission-connected to the disassembly member 103, and the lifting mechanism 102 is arranged on the side piece of the disassembly member 103 along the lifting direction, and the lifting mechanism 102 drives the disassembly member 103 to rise and fall relative to the helmet 200. Compared with the previous embodiment, this embodiment can reduce the number of lifting mechanisms 102, and only one lifting mechanism 102 is required to meet the demand of driving the disassembly member 103.

[0126] In addition, in this embodiment, the lifting mechanism 102 can be arranged on one side or both sides of the lifting direction according to specific needs, and the arrangement on both sides can ensure that the disassembly part 103 is lifted and lowered smoothly along the lifting direction. Among them, the lifting mechanism 102 can be a cylinder mechanism, or it can be a screw drive mechanism or other mechanism that can realize linear drive. When the lifting mechanism 102 is arranged on both sides of the lifting direction, the two cylinder mechanisms or the two screw drive mechanisms are arranged in parallel. In this embodiment, since the lifting mechanism 102 is arranged inside the shell 101, it is always connected to the disassembly part 103, and there is no need to be connected to the helmet 200 that requires high-frequency disassembly and assembly, so the probability of damage to the lifting mechanism 102 can also be reduced.

[0127] In some embodiments, the helmet 200 includes a plurality of locking mechanisms 202, which are sequentially arranged along the circumference of the helmet shell 201, and the plurality of locking mechanisms 202 are used to lock or unlock the same replaceable liner 300. The disassembly device 100 includes a plurality of disassembly members 103, and the plurality of disassembly portions 1031 of the plurality of disassembly members 103 are used to be arranged one-to-one with the plurality of locking mechanisms 202.

[0128] In some specific embodiments, the replaceable liner 300 includes a liner 300 body and a plurality of detachable parts 302, and the plurality of detachable parts 302 are arranged at intervals along the periphery of the liner 300 body. Each detachable part 302 is provided with a fixed connection part 3021 and a detachable connection part 3022, and each detachable part 302 is fixedly connected to the liner 300 body through the fixed connection part 3021, and all detachable connection parts 3022 of the detachable parts 302 are used for detachably connecting to the helmet shell 201 of the helmet 200.

[0129] When a plurality of locking mechanisms 202 provided in the above-mentioned embodiments are provided on the inner wall of the helmet shell 201 of the helmet 200, a plurality of detachable connecting portions 3022 of a plurality of detachable parts 302 are arranged one-to-one with the plurality of locking mechanisms 202, and a plurality of disassembly portions 1031 of a plurality of disassembly parts 103 can disassemble a plurality of detachable parts 302 from a plurality of locking mechanisms 202 one-to-one. After the plurality of detachable parts 302 are disassembled, the lining 300 where the plurality of detachable parts 302 are located is disassembled.

[0130] In some embodiments, the locking mechanism 202 includes two locking members, each of which has a proximal end 2024 and a distal end 2025 opposite to each other along a first direction, and the proximal end 2024 of any locking member is arranged between the proximal end 2024 and the distal end 2025 of the other locking member along the first direction; wherein at least one distal end 2025 is used to lock the replaceable liner 300.

[0131] Any locking member can move relative to the other locking member in the first direction. When the locking mechanism 202 is in the locked position, the two distal ends 2025 are in positions away from each other; when the locking mechanism 202 is in the unlocked position, the two distal ends 2025 are in positions close to each other.

[0132] When the lifting mechanism 102 drives one of the helmet 200 and the disassembly member 103 to be inserted into the other along the lifting direction, the disassembly portion 1031 enters between the two proximal ends 2024 and drives the two proximal ends 2024 to move away from each other in the first direction, so that the locking mechanism 202 is switched from the locked position to the unlocked position; wherein, the first direction is perpendicular to the lifting direction.

[0133] In this embodiment, the two locking members are respectively a first locking member 2021 and a second locking member 2022. The first locking member 2021 and the second locking member 2022 are both moving members and can move relative to each other. That is to say, the first locking member 2021 can move relative to the second locking member 2022 in the first direction, and the second locking member 2022 can also move relative to the first locking member 2021 in the first direction. For example, the first locking member 2021 can be directly slidably connected to any one of the following helmet shell 201, locking shell 204, and cage 203, and the second locking member 2022 can be directly slidably connected to any one of the following helmet shell 201, locking shell 204, and cage 203. Among them, preferably, the first locking member 2021 and the second locking member 2022 can be slidably connected to the same component. For example, the first locking member 2021 and the second locking member 2022 are both slidably connected to the cage 203.

[0134] For another example, the first locking member 2021 is directly slidably connected to any one of the helmet shell 201, locking shell 204, and cage 203, and the second locking member 2022 is slidably connected to the first locking member 2021. For example, the second locking member 2022 is slidably connected to the first locking member 2021 at the plane position in contact with the first locking member 2021. For another example, the second locking member 2022 is directly slidably connected to any one of the helmet shell 201, locking shell 204, and cage 203, and the first locking member 2021 is slidably connected to the second locking member 2022. For example, the first locking member 2021 is slidably connected to the second locking member 2022 at the plane position in contact with the second locking member 2022.

[0135] In this embodiment, the first locking member 2021 has a locking position and an unlocking position, and is capable of switching between the locking position and the unlocking position. The second locking member 2022 has a locking position and an unlocking position, and is capable of switching between the locking position and the unlocking position. The locking position of the first locking member 2021 and the locking position of the second locking member 2022 are symmetrically arranged with respect to the central axis of the locking mechanism 202, and the unlocking position of the first locking member 2021 and the unlocking position of the second locking member 2022 are symmetrically arranged with respect to the central axis of the locking mechanism 202.

[0136] When the lifting mechanism 102 drives one of the helmet 200 and the disassembling member 103 to be inserted into the other along the lifting direction, the disassembling portion 1031 enters between the two proximal ends 2024 and drives the two proximal ends 2024 to move away from each other in the first direction, that is, the distal ends 2025 of the first locking member 2021 and the second locking member 2022 can approach each other simultaneously in the first direction, and thus switch from the locking position to the unlocking position. More specifically, when the first locking member 2021 is in the locking position and the second locking member 2022 is in the locking position, the two distal ends 2025 of the first locking member 2021 and the second locking member 2022 are in positions away from each other. When the first locking member 2021 is in the unlocking position and the second locking member 2022 is in the unlocking position, the two distal ends 2025 of the first locking member 2021 and the second locking member 2022 are in positions close to each other.

[0137] In this embodiment, preferably, the first locking member 2021 and the second locking member 2022 have the same structure, and the entire locking structure has a central axis located between the two proximal ends 2024, and the entire locking mechanism 202 is symmetrically arranged with respect to the central axis.

[0138] In some embodiments, the locking mechanism 202 includes two elastic members 2023. One elastic member 2023 is connected between the proximal end 2024 of the first locking member 2021 and the distal end 2025 of the second locking member 2022, and the other elastic member 2023 is connected between the distal end 2025 of the first locking member 2021 and the proximal end 2024 of the second locking member 2022. The disassembling portion 1031 is configured to enter between the two proximal ends 2024 along the lifting direction and overcome the elastic force of the elastic member 2023, so as to drive the two proximal ends 2024 to move away from each other in the first direction.

[0139] During the process that the second locking member 2022 switches from the locked position to the unlocked position along the first direction and the first locking member 2021 switches from the locked position to the unlocked position along the first direction, the proximal end 2024 of the second locking member 2022 and the distal end 2025 of the first locking member 2021 approach each other and simultaneously drive the elastic member 2023 connected therebetween to store elastic force. The elastic member 2023 stores elastic force by being compressed. Synchronously, the distal end 2025 of the second locking member 2022 and the proximal end 2024 of the first locking member 2021 approach each other and synchronously drive the elastic member 2023 connected therebetween to store elastic force. The elastic member 2023 also stores elastic force by being compressed. Under the action of the elastic forces of the two elastic members 2023, the second locking member 2022 switches from the unlocked position to the locked position and the first locking member 2021 synchronously switches from the unlocked position to the locked position.

[0140] In some embodiments, a pair of proximal force-receiving sides 2024a opposite to each other are provided on the two proximal ends 2024. The proximal force-receiving sides 2024a are inclined relative to the first direction, and the pair of proximal force-receiving sides 2024a are symmetrically arranged along the first direction. Proximal force-applying parts 1031a are respectively provided on both sides of the disassembly part 1031 along the first direction. The two proximal force-applying sides 1031b of the two proximal force-applying parts 1031a are symmetrically arranged along the first direction. The two proximal force-applying sides 1031b are used to abut against the pair of proximal force-receiving sides 2024a.

[0141] When the lifting mechanism 102 drives one of the helmet 200 and the disassembly member 103 to be inserted into the other along the lifting direction, the disassembly part 1031 enters between the two proximal ends 2024 and drives the two proximal ends 2024 to move away from each other along the first direction. By the pair of proximal force-receiving sides 2024a of the pair of proximal force-applying parts 1031a acting on the pair of proximal force-receiving sides 2024a of the two proximal ends 2024, forcing the two proximal ends 2024 to move away from each other, the two distal ends 2025 of the two locking members approach each other, and the two locking members simultaneously switch from the locked position to the unlocked position, and the replaceable inner lining 300 is unlocked and can be detached from the locking mechanism 202.

[0142] In some embodiments, a through hole 30222 is provided at the center of the detachable connection part 3022 described above. The through hole 30222 can be disposed opposite to the through space 2026 between the two proximal ends 2024 of the locking mechanism 202. The hole edge of the through hole 30222 includes two first extension parts 30222a and two second extension parts 30222b that are oppositely arranged. The distance from the first extension part 30222a to the hole axis of the through hole 30222 is greater than the distance from the second extension part 30222b to the hole axis. The first extension parts 30222a and the second extension parts 30222b are alternately arranged along the circumferential direction of the through hole 30222. Among them, both the through hole 30222 and the through space 2026 are used for passing the disassembly part 1031 of the disassembly member 103.

[0143] Among them, the maximum distance between the two first extension parts 30222a in the first direction is greater than the maximum distance between the two proximal end applying force parts 1031a in the first direction, so as to allow the two proximal end applying force parts 1031a to smoothly pass through the space between the two first extension parts 30222a, contact the two proximal end force receiving sides 2024a of the two proximal ends 2024 on the two locking members and apply the second external force described above, and allow the two proximal end applying force parts 1031a to smoothly withdraw from the through hole 30222 and the through space 2026.

[0144] Furthermore, a pulling part 1031c is provided on the disassembly part 1031 along a direction perpendicular to the first direction. The pulling part 1031c is provided with an inclined surface. In other words, the pulling part 1031c and the proximal end applying force part 1031a are arranged at intervals along the circumferential direction of the disassembly part 1031. The pulling part 1031c includes a main body part a and a telescopic part b. The main body part a is connected to the disassembly part 1031 through the telescopic part b, so that the pulling part 1031c can telescopically move relative to the disassembly part 1031 along a direction perpendicular to the first direction.

[0145] Furthermore, the distance from the edge of the second extension part 30222b to the central axis of the through hole 30222 is less than the maximum distance from the pulling part 1031c to the central axis of the disassembly part 1031 when the pulling part 1031c is in the extended state, and greater than the maximum distance from the pulling part 1031c to the central axis of the disassembly part 1031 when the pulling part 1031c is in the contracted state. The natural state of the second extension part 30222b is the extended state. Due to the setting of the inclined surface, the second extension part 30222b can prevent the extended pulling part 1031c from passing through the through hole 30222 when the replacement part withdraws from the through hole 30222, and squeeze the pulling part 1031c into the contracted state and allow the pulling part 1031c to pass through the through hole 30222 when the replacement part enters the through hole 30222.

[0146] Specifically, when the disassembly portion 1031 enters the penetration hole 30222 and the penetration space 2026, the take-away portion 1031c is squeezed by the second expansion portion 30222b and switches from the extended state to the retracted state. After the take-away portion 1031c passes through the penetration hole 30222 and enters the penetration space 2026, the squeezing force of the second expansion portion 30222b on the take-away portion 1031c disappears, and the take-away portion 1031c naturally switches to the extended state. Simultaneously, the two proximal force-applying portions 1031a apply a second external force to the two proximal ends 2024, and drive the two distal ends 2025 of the first locking member 2021 and the second locking member 2022 to approach each other, and the replaceable liner 300 is disassembled. When the disassembly portion 1031 exits the penetration space 2026 and the penetration hole 3022, the take-away portion 1031c takes away the replaceable liner 300.

[0147] like Figures 20 to 26 As shown, based on the above-mentioned lifting mechanism 102, the helmet 200 can be driven to lift and lower. The lifting mechanism 102 includes a lifting assembly 1021 and a driven part 1022, which is driven to extend along the circumference of the disassembly opening 1011, and the lifting direction of the driven part 1022 is perpendicular to the circumference of the disassembly opening 1011. The driven part 1022 is connected to the lifting assembly 1021 by transmission, and is configured to be able to approach or move away from the disassembly opening 1011 along the lifting direction under the drive of the lifting assembly 1021; the detachable assembly 104 is arranged on the side of the driven part 1022 facing the disassembly opening 1011, and the detachable assembly 104 is used for detachably installing the helmet 200. When the helmet 200 is installed on the detachable assembly 104, the wearing opening 2011 and the disassembly opening 1011 of the helmet 200 are coaxially arranged along the lifting direction.

[0148] The disassembly device 100 provided in this embodiment has a driven part 1022 that is transmission-connected to the lifting assembly 1021 and configured to be able to approach or move away from the disassembly opening 1011 along the lifting direction under the drive of the lifting assembly 1021. The detachable assembly 104 is arranged on the driven part 1022 on one side facing the disassembly opening 1011, and is used to detachably install the helmet 200. When the helmet 200 is installed on the detachable assembly 104, the wearing opening 2011 and the disassembly opening 1011 of the helmet 200 are coaxially arranged along the lifting direction. In this way, the lifting mechanism 102 drives the helmet 200 to lift and lower, so that the helmet 200 can complete the removal of the liner 300 in the landing position.

[0149] In some embodiments, one end of the driven component 1022 along the circumferential direction is drivingly connected to the lifting component 1021 , and the detachable component 104 is disposed on the other end of the driven component 1022 along the circumferential direction.

[0150] In this way, the detachable component 104 and the lifting component 1021 are circumferentially offset, which is beneficial to making full use of the circumferential space for arrangement, and can save the space in the lifting direction and reduce the overall volume of the disassembling device 100.

[0151] In some embodiments, the driven member 1022 is a cantilever beam member, and the other end of the driven member 1022 is suspended. The cantilever beam member can provide a good support basis for the detachable installation of the helmet 200, making the support received by the helmet 200 more stable and reliable.

[0152] Moreover, the lifting component 1021 is only provided on one side of the driving member 1021a in the circumferential direction, and the other side is suspended, which can make the driven member 1022 have a slight floating in the lifting direction. When the locking mechanism 202 on the helmet 200 and the disassembling member 103 are inserted, it can avoid damaging the lifting component 1021 due to overly rigid contact.

[0153] In some embodiments, the lifting component 1021 includes a driving member 1021a and a transmission lead screw 1021b. The driving member 1021a and the transmission lead screw 1021b are coaxially arranged in the lifting direction. The driven member 1022 is provided with a transmission hole 1022a. The transmission hole 1022a penetrates the driven member 1022 in the lifting direction. The transmission lead screw 1021b is inserted into the transmission hole 1022a in a transmission manner and is configured to drive the driven member 1022 to move in the lifting direction through the transmission hole 1022a under the drive of the driving member 1021a.

[0154] Through the arrangement of the transmission lead screw 1021b, and by providing the driven member 1022 with the transmission hole 1022a and inserting the transmission lead screw 1021b into the transmission hole 1022a in a transmission manner, the transmission lead screw 1021b can not only provide a guiding function for the lifting of the driven member 1022, but also enable the driven member 1022 to lift stably. Therefore, the lifting stability of the detachable component 104 and the helmet 200 can be improved.

[0155] In some embodiments, the lifting component 1021 further includes an optical axis 1021c. The optical axis 1021c is fixed relative to the housing 101. The optical axis 1021c and the transmission lead screw 1021b are parallel and spaced in the circumferential direction; the driven member 1022 is provided with an optical hole 1022b. The optical hole 1022b penetrates the driven member 1022 in the lifting direction. The optical hole 1022b is sleeved on the optical axis 1021c and can move along the optical axis 1021c.

[0156] Through the arrangement of the optical axis 1021c, and by providing the driven member 1022 with the optical hole 1022b and inserting the optical axis 1021c into the optical hole 1022b in a transmission manner, the optical axis 1021c can not only provide a guiding function for the lifting of the driven member 1022, but also enable the driven member 1022 to lift stably. Therefore, the lifting stability of the detachable component 104 and the helmet 200 can be further improved.

[0157] In some embodiments, the optical axis 1021c and the detachable assembly 104 are circumferentially disposed on both sides of the transmission screw 1021b. In other words, the optical axis 1021c is optionally disposed on a side of the transmission screw 1021b away from the driven component 1022. In other embodiments, the transmission screw 1021b and the detachable assembly 104 may be circumferentially disposed on both sides of the optical axis 1021c.

[0158] In some embodiments, the disassembly device 100 includes two lifting mechanisms 102 and two detachable components 104. The two driven parts 1022 in the two lifting mechanisms 102 are arranged opposite to each other along the radial direction of the housing 101, and the two detachable components 104 are arranged opposite to each other along the radial direction of the housing 101. The two detachable components 104 are arranged one-to-one on the two driven parts 1022. The structures of the two driven parts 1022 are the same or different, and the structures of the two detachable components 104 are the same or different.

[0159] By providing two detachable components 104 and two lifting mechanisms 102 , it is possible to ensure that the helmet 200 can be lifted and lowered smoothly as a whole, and then plugged into the mounting parts with high precision, thereby successfully completing the removal of the replaceable liner 300 .

[0160] like Figures 37 to 42 As shown, in some embodiments, the detachable component 104 includes a movable component 1041 and a buffer 1042, and the movable component 1041 is used for detachably installing the helmet 200. The buffer 1042 is extended along the lifting direction, one end of the buffer 1042 is connected to the movable component 1041, and the other end of the buffer 1042 is directly or indirectly connected to the driven component 1022. The buffer 1042 is configured to provide buffering when the helmet 200 is subjected to an external force directed to the disassembly opening 1011 along the lifting direction, and the movable component 1041 is driven to move relative to the driven component 1022.

[0161] The buffer 1042 can be any elastic component, for example, a linear spring. One end of the buffer 1042 is connected to the movable component 1041, and the movable component 1041 can detachably install the helmet 200. The other end of the buffer 1042 is directly or indirectly connected to the driven component 1022. In the process of mutual insertion between the locking mechanism 202 of the helmet 200 and the disassembly portion 1031 of the disassembly member 103, the reaction force of the disassembly member 103 on the helmet 200 can be buffered by the buffer 1042, and the helmet 200 can be allowed to move slightly backward in the opposite direction of insertion. In this way, the reaction force generated when the locking mechanism 202 of the helmet 200 and the disassembly portion 1031 of the disassembly member 103 are plugged into each other can be avoided to have an adverse effect on the lifting mechanism 102, and this part of the force can be absorbed by the buffer 1042.

[0162] In some embodiments, the detachable component 104 includes two buffer members 1042 which are circumferentially arranged on both sides of the movable component 1041. By means of the two buffer members 1042 arranged circumferentially, the buffering effect can be more effective and balanced.

[0163] In some embodiments, the detachable component 104 further includes a fixing member 1043 which has a fixed end 1043a and a limiting end 1043b. The fixed end 1043a is fixedly connected to the driven member 1022, and the limiting end 1043b and the driven member 1022 are spaced apart in the lifting direction. The movable component 1041 has a connecting end which is located between the limiting end 1043b and the driven member 1022 in the lifting direction, and the buffer member 1042 is connected between the limiting end 1043b and the connecting end. The buffer member 1042 is configured to be compressed when an external force in the lifting direction pointing to the disassembly opening 1011 is applied to the helmet 200 and to press the connecting end against the driven member 1022 when the external force is removed.

[0164] The fixed end 1043a of the fixing member 1043 is connected to the driven member 1022. After the helmet 200 lands in place, the position of the fixing member 1043 relative to the driven member 1022 is fixed, that is, the position relative to the lifting component 1021 is fixed. The connecting end of the movable component 1041 is located between the limiting end 1043b and the driven member 1022, and the buffer member 1042 is connected between the limiting end 1043b and the connecting end. Thus, when the helmet 200 is subjected to a reaction force and moves slightly backward, the movable component 1041 is driven by the helmet 200 to move slightly backward synchronously, that is, move toward the limiting end 1043b, and then the buffer member 1042 is compressed to absorb the reaction force.

[0165] Based on the above detachable component 104 for detachably mounting the helmet 200, in some embodiments, at least two detachable components 104 are provided near the disassembly opening 1011. The two detachable components 104 are arranged at intervals along the circumference of the disassembly opening 1011 or arranged in pairs along the radius of the disassembly opening 1011. The two detachable components 104 are used for detachably connecting with two detachable structures 2012 on the helmet 200, so that the helmet 200 can be detachably connected to the disassembly device 100 to complete the replacement of the inner lining 300.

[0166] In the embodiment of the present application, two detachable components 104 in the disassembly device 100 are arranged at intervals along the circumferential direction of the disassembly opening 1011 or arranged in pairs along the radial direction of the disassembly opening 1011. The two detachable components 104 are used for detachably connecting with two detachable structures 2012 on the helmet 200, so that the helmet 200 can be detachably connected to the disassembly device 100 to complete the replacement of the inner lining 300. Through the detachable components 104, the user can disassemble and assemble the helmet 200 by himself. When the helmet 200 is detachably connected to the disassembly device 100, the disassembly device 100 can complete the replacement of the inner lining 300 of the helmet 200. When the helmet 200 is detached from the disassembly device 100, the user can wear the helmet 200 with the replaced inner lining 300 by himself.

[0167] In some embodiments, the two detachable components 104 are arranged in pairs along the radial direction of the disassembly opening 1011, which are respectively a first detachable component 104a and a second detachable component 104b; the structures of the first detachable component 104a and the second detachable component 104b are different. The first detachable component 104a is used for detachably clamping with a first detachable structure 2012a on the front end side of the helmet 200, and the second detachable component 104b is used for detachably clamping with a second detachable structure 2012b on the rear end side of the helmet 200.

[0168] By the first detachable component 104a and the second detachable component 104b arranged along the radial direction, the front end side and the rear end side of the helmet 200 can be respectively detachably installed on the disassembly device 100, ensuring the stability and balance of the helmet 200 during the lifting process.

[0169] In some embodiments, the second detachable component 104b includes a first elastic member 10413 extending along the radial direction, and the first detachable component 104a includes a bayonet structure or a convex structure extending along the radial direction; the first elastic member 10413 is configured such that when the helmet 200 is clamped to the first detachable component 104a through the first detachable structure 2012a, the second detachable structure 2012b overcomes the first elastic force of the first elastic member 10413 and is clamped to the second detachable component 104b by means of the rigid abutting force against the first detachable component 104a, and remains clamped to the second detachable component 104b under the action of the elastic force of the first elastic member 10413.

[0170] In this embodiment, by means of the rigid abutting force against the first detachable component 104a, the following second detachable structure 2012b can overcome the first elastic force of the first elastic member 10413 and be snap-fitted to the second detachable component 104b, and remain snap-fitted to the second detachable component 104b under the elastic force of the first elastic member 10413. Thus, it helps the user to perform labor-saving operations when detachably installing the helmet 200, and the user can conveniently install the helmet 200 between the first detachable component 104a and the second detachable component 104b. Wherein, the first detachable structure 2012a and the second detachable structure 2012b are arranged oppositely along the front-back direction of the helmet 200.

[0171] In some embodiments, the second detachable component 104b further includes a second elastic member 10415. The second elastic member 10415 and the first elastic member 10413 are arranged in a radial order and are angled; the second elastic member 10415 is configured to act on the second elastic member 10415 synchronously and store elastic force when the second detachable structure 2012b abuts against the second detachable component 104b, and the second elastic member 10415 is used to assist the second detachable structure 2012b to disengage from the second detachable component 104b through the stored elastic force.

[0172] The first elastic member 10413 extends along the radial direction of the disassembly device 100, while the second elastic member 10415 is angled with respect to the extension direction of the first elastic member 10413, so that when the helmet 200 is installed towards the second detachable component 104b, it acts on the second elastic member 10415 and stores elastic force. Correspondingly, when removing the helmet 200, the second elastic member 10415 can assist the helmet 200 to bounce upwards and disengage from the second detachable component 104b through the stored elastic force.

[0173] In some specific embodiments, the second detachable component 104b includes the above-mentioned movable component 1041.

In this way, the movable part can be balanced and elastically supported between the two fixing members 1043 through the main body member 10411, that is, the movable part is balanced and elastically supported on the driven member 1022.

[0175] Among them, two first elastic members 10413 can be provided. The first sliding member 10412 is provided with two setting holes 10412a extending radially. The two first elastic members 10413 are respectively arranged in the two setting holes 10412a. The side of the first elastic member 10413 facing away from the first sliding member 10412 can be closed and fixed by the side plate 10411a, and the side plate 10411a is part of the main body member 10411.

[0176] Among them, the first detachable structure 2012a of the helmet 200 is located on the outer wall of the front end side of the helmet shell 201, and the second detachable structure 2012b is located on the outer wall of the rear end side of the helmet shell 201.

Among them, the sliding guide surface c is used to provide guidance when the second detachable structure 2012b is installed on the disassembly device 100.

[0177] Correspondingly, the side surface of the first sliding member 10412 facing away from the first elastic member 10413 is provided with a sliding guide surface c and a protruding portion e. Along the direction from the disassembly opening 1011 to the inside of the housing 101, the sliding guide surface c and the protruding portion e are arranged in sequence and are smoothly connected; the sliding guide surface c gradually approaches the central axis of the housing 101 along the direction from the disassembly opening 1011 to the inside of the housing 101, and the protruding portion e protrudes towards the central axis along the meridional direction of the housing 101; among them, the sliding guide surface c is used to provide guidance when the second detachable structure 2012b is installed on the second detachable component 104b, and the protruding portion e is used for detachably clamping to the second detachable structure 2012b.

[0178] In this way, during the installation of the helmet 200, the second detachable structure 2012b of the helmet 200 is aligned with the main body 10411 of the second detachable component 104b and the helmet 200 is pressed down, and the sliding guide surface c is used to provide a guiding effect for the second detachable structure 2012b to be installed toward the second detachable component 104b, so that the protrusion e can be detachably connected to the second detachable structure 2012b. Specifically, a slot structure can be set on the main body 10411, and the protrusion e can be connected to the slot structure.

[0179] Among them, a position detection device 10416 can be set on the main body 10411 to detect whether the helmet is installed in place.

[0180] The first elastic member 10413 and the first sliding member 10412 may be sequentially arranged in a radially inward or radially outward direction. In some embodiments, the first elastic member 10413 is radially arranged outside the first sliding member 10412, one end of the first elastic member 10413 facing inward is connected to the first sliding member 10412, and the other end of the first elastic member 10413 facing outward is fixed relative to the main member 10411.

[0181] In some specific embodiments, the second detachable component 104b further includes a second sliding member 10414 and a second elastic member 10415. Along the direction from the disassembly opening 1011 to the inside of the housing 101, the first elastic member 10413 and the second elastic member 10415 are arranged in sequence, and the first sliding member 10412 and the second sliding member 10414 are arranged in sequence; one end of the second elastic member 10415 is connected to the second sliding member 10414, and the other end is fixed relative to the main body 10411; the second sliding member 10414 is slidably arranged on the main body 10411, and the sliding path of the second sliding member 10414 and the extension direction of the second elastic member 10415 are both at an angle to the radial direction.

[0183] When the helmet 200 is installed toward the second detachable component 104b, it acts on the two second elastic members 10415 and makes them store elastic force. Correspondingly, when the helmet 200 is removed, the second elastic members 10415 can assist the helmet 200 to bounce upward and detach from the second detachable component 104b through the stored elastic force.

[0184] like Figures 18 to 20As shown in the figure, the shared helmet 200 provided by the embodiment of the present application includes a helmet shell 201, at least two locking mechanisms 202, and at least two detachable structures 2012. The locking mechanisms 202 are provided on the inner wall of the helmet shell 201. The two locking mechanisms 202 are arranged in pairs along the meridian direction of the helmet shell 201 or are spaced along the circumferential direction of the helmet shell 201. The locking mechanisms 202 are used for detachably connecting the replaceable inner lining 300. The detachable structures 2012 are provided on the outer wall of the helmet shell 201. The two detachable structures 2012 are arranged in pairs along the meridian direction of the helmet shell 201 or are spaced along the circumferential direction of the helmet shell 201. The detachable structures 2012 are used for detachably connecting the dismounting device 100, so that the dismounting device 100 can disassemble the replaceable inner lining 300 of the shared helmet 200.

[0185] Since the locking mechanisms 202 are provided on the inner wall of the helmet shell 201, the two locking mechanisms 202 are arranged in pairs along the meridian direction of the helmet shell 201 or are spaced along the circumferential direction of the helmet shell 201, and the locking mechanisms 202 are used for detachably connecting the replaceable inner lining 300, so that the inner lining 300 of the helmet 200 can be replaced, and thus the sanitary safety of the shared helmet 200 can be ensured.

[0186] Furthermore, the detachable structures 2012 are provided on the outer wall of the helmet shell 201. The two detachable structures 2012 are arranged in pairs along the meridian direction of the helmet shell 201 or are spaced along the circumferential direction of the helmet shell 201. The detachable structures 2012 are used for detachably connecting the dismounting device 100, so that the dismounting device 100 can disassemble the replaceable inner lining 300 of the shared helmet 200. When the helmet 200 is detachably connected to the dismounting device 100, the dismounting device 100 can complete the replacement of the inner lining 300 of the helmet 200. When the helmet 200 is detached from the dismounting device 100, the user can wear the helmet 200 with the replaced inner lining 300 by himself.

[0187] In some embodiments, the helmet shell 201 includes a main body shell 2013 and at least two extension shells 2014. The extension shells 2014 are integrally connected to the periphery of the main body shell 2013 and protrude from the main body shell 2013 along the meridian direction of the main body shell 2013. Among them, at least two locking mechanisms 202 are detachably installed one by one in at least two mounting shells.

[0188] By distinguishing the main body shell 2013 and the extension shells 2014, the part for the user to wear and the part for detachably installing the inner lining 300 can be distinguished, so that the inner lining 300 body is adapted to the inner wall of the main body shell 2013, and the detachable part 302 is correspondingly installed on the part of the extension shell 2014. In this way, the rigid locking mechanisms 202 and the detachable part 302 will not have an adverse impact on the wearing comfort of the user.

[0189] In some embodiments, the helmet 200 includes a pair of detachable structures 2012, namely a first detachable structure 2012a and a second detachable structure 2012b respectively; both the first detachable structure 2012a and the second detachable structure 2012b are integrally formed on the helmet shell 201, and the structures of the first detachable structure 2012a and the second detachable structure 2012b are different. Among them, the first detachable structure 2012a is located on the outer wall of the front end side of the helmet shell 201, and the second detachable structure 2012b is located on the outer wall of the rear end side of the helmet shell 201.

[0190] In some specific embodiments, the helmet shell 201 has a wearing opening 2011 and a vertex f that are oppositely arranged along its central axis; the second detachable structure 2012b includes a sliding guide surface c and a clamping groove d, along the direction from the wearing opening 2011 to the vertex f, the sliding guide surface c and the clamping groove d are arranged in sequence and are smoothly connected. The sliding guide surface c gradually moves away from the central axis along the direction from the wearing opening 2011 to the vertex f, and the clamping groove d is recessed towards the inside of the helmet shell 201 along the meridian direction of the helmet shell 201. Among them, the sliding guide surface c is used to provide guidance when the second detachable structure 2012b is installed on the disassembly device 100. The first detachable structure 2012a is a bayonet structure or a convex structure, and the first detachable structure 2012a extends along the meridian direction of the helmet shell 201.

[0191] Correspondingly, the structures of the above-mentioned first detachable component 104a and second detachable component 104b are set differently, so that when the first elastic member 10413 is configured such that the helmet 200 is clamped to the first detachable component 104a through the following first detachable structure 2012a, the following second detachable structure 2012b can overcome the first elastic force of the first elastic member 10413 and be clamped to the second detachable component 104b by means of the rigid abutting force with the first detachable component 104a, and remain clamped to the second detachable component 104b under the elastic force of the first elastic member 10413. In this way, it helps the user to perform labor-saving operations when detachably installing the helmet 200, and the user can conveniently install the helmet 200 between the first detachable component 104a and the second detachable component 104b. Among them, the first detachable structure 2012a and the second detachable structure 2012b are arranged oppositely along the front-rear direction of the helmet 200.

[0192] In some embodiments, the helmet shell 201 has a first peripheral edge 2015 and a second peripheral edge 2016, and the first peripheral edge 2015 and the second peripheral edge 2016 are respectively located on both sides of the connection line between the front end side and the rear end side. The helmet 200 includes two pairs of locking mechanisms 202. In any pair of two locking structures, one locking mechanism 202 is arranged on the first peripheral edge 2015, and the other locking mechanism 202 is arranged on the second peripheral edge 2016.

[0193] As described above, the first detachable structure 2012a is located on the outer wall of the front end side of the helmet shell 201, the second detachable structure 2012b is located on the outer wall of the rear end side of the helmet shell 201, and the locking mechanism 202 is provided on both sides of the connection line between the front end side and the rear end side of the helmet 200. That is to say, the locking mechanism 202 and the first detachable structure 2012a and the second detachable structure 2012b are circumferentially spaced apart to prevent interference between the detachable installation of the helmet 200 and the detachable of the inner lining 300.

[0194] In some embodiments, the helmet shell 201 has a central axis passing through the apex f of the helmet shell 201; along the direction of the central axis, the locking mechanism 202, the detachable structure 2012, and the apex f are sequentially spaced apart. That is to say, the locking mechanism 202 and the first detachable structure 2012a and the second detachable structure 2012b are axially spaced apart along the helmet 200 to prevent the detachable installation position of the helmet 200 and the detachable position of the inner lining 300 from being at the same height, making it difficult to set up the lifting mechanism 102.

[0195] In some embodiments, the locking mechanism 202 includes two locking members; the locking member has a proximal end 2024 and a distal end 2025 opposite to each other in the first direction, and the proximal end 2024 of any one locking member is arranged between the proximal end 2024 and the distal end 2025 of the other locking member in the first direction; wherein, at least one distal end 2025 is used to lock the first component; at least one locking member can move relative to the other locking member in the first direction and has a locking position and an unlocking position and can be switched between the two; wherein, when the locking member is in the locking position, the two distal ends 2025 are in a position away from each other and lock the replaceable inner lining 300; when the locking member is in the unlocking position, the two distal ends 2025 are in a position close to each other and unlock the replaceable inner lining 300. Wherein, the first direction is the tangent direction of the intersection of the central axis of the locking member and the circumferential direction of the helmet shell 201; or, the first direction is the meridian direction of the helmet shell 201.

[0196] In some embodiments, the locking mechanism 202 further includes a cage 203, the cage 203 is connected to the inner wall of the helmet shell 201, and a first slideway 2031 and a second slideway 2032 are provided on the side of the cage 203 facing away from the inner wall of the helmet shell 201; the first slideway 2031 and the second slideway 2032 are arranged in sequence in the first direction, and both the first slideway 2031 and the second slideway 2032 extend in the first direction; the two locking members are respectively a first locking member 2021 and a second locking member 2022, the first locking member 2021 is slidably connected to the first slideway 2031, and the second locking member 2022 is slidably connected to the second slideway 2032.

[0197] In a specific embodiment, the first slideway 2031 may include a first proximal slideway 2031a and a first distal slideway 2031b. The first proximal slideway 2031a and the first distal slideway 2031a are arranged in sequence along the first direction, and both the first proximal slideway 2031a and the first distal slideway 2031a extend along the first direction. The proximal end 2024 and the distal end 2025 of the first locking member 2021 are slidably connected to the first proximal slideway 2031a and the first distal slideway 2031a respectively.

[0198] In a specific embodiment, the second slideway 2032 may include a second proximal slideway 2032a and a second distal slideway 2032b. The second proximal slideway 2032a and the second distal slideway 2032b are arranged in sequence along the first direction, and both the second proximal slideway 2032a and the second distal slideway 2032b extend along the first direction. The proximal end 2024 and the distal end 2025 of the second locking member 2022 are slidably connected to the second proximal slideway 2032a and the second distal slideway 2032a respectively.

[0199] As a preferred embodiment of the locking mechanism 202 of the present application, the locking mechanism 202 may further include a locking housing 204. The locking housing 204 may be fixedly connected to the inner wall of the helmet shell 201 of the helmet 200. The upper end of the cage 203 is connected to the locking housing 204. The above-mentioned first slideway 2031 and the second slideway are provided at the lower end of the cage 203. The first locking member 2021 and the second locking member 2022 are respectively slidably connected to the lower end of the cage 203, that is, in the direction towards the wearing opening 2011.

[0200] In the first application embodiment, the automatic disassembly device provided by the embodiment of the present application can be used alone.

[0201] In the second application embodiment, the automatic disassembly device provided by the embodiment of the present application can also be used in combination with the automatic installation system of the helmet liner. The two can be arranged at intervals in the horizontal direction. The user can manually switch the helmet, or drive the automatic disassembly device and the automatic installation device to switch at the same position through a horizontal movement mechanism, so as to complete the disassembly and installation of the liner at the same position.

[0202] Such as Figures 27 to 28As shown, the automatic helmet lining installation system includes a helmet 200 and an installation device 100. The helmet 200 is used for detachably installing on the installation device 100. The helmet 200 includes a helmet shell 201 and a locking mechanism 202. The locking mechanism 202 is provided on the inner wall of the helmet shell 201 and is used for locking or unlocking the replaceable lining 300 of the helmet 200. The locking mechanism 202 includes at least one elastic member 2023. The locking mechanism 202 has a locking position and an unlocking position and can be switched between the two. The locking mechanism 202 can be forced to be in the unlocking position by an external force against the elastic force of the elastic member 2023 and be in the locking position under the action of the elastic force of the elastic member 2023.

[0203] The installation device 100 includes a lifting mechanism 102 and an installation member 103. The installation member 103 has an interconnected installation part 1032 and a storage part. The replaceable lining 300 is provided with a detachable part 302 and is sleeved on the storage part through the detachable part 302. When the helmet 200 is installed on the installation device 100, the installation part 1032, the detachable part 302, and the locking mechanism 202 are coaxially arranged along the lifting direction of the lifting mechanism 102. The lifting mechanism 102 can drive one of the helmet 200 and the installation member 103 to move up and down relative to the other, so as to force the detachable part 302 to act on the locking mechanism 202 and overcome the elastic force of the elastic member 2023, thereby switching the locking mechanism 202 from the locking position to the unlocking position and locking the detachable part 302 under the action of the elastic force of the elastic member 2023.

[0204] Among them, the lifting mechanism 102 can drive one of the helmet 200 and the installation member 103 to move up and down relative to the other, so as to force the detachable part 302 to act on the locking mechanism 202 and overcome the elastic force of the elastic member 2023, thereby switching the locking mechanism 202 from the locking position to the unlocking position and locking the detachable part 302 under the action of the elastic force of the elastic member 2023, and then completing the automatic installation of the replaceable lining 300. By arranging the lifting mechanism 102 in the installation device 100, the lifting mechanism 102 selectively drives the helmet 200 or the installation member 103 to conveniently install the disposable lining 300 on the helmet 200.

[0205] In some embodiments, the helmet 200 includes a plurality of locking mechanisms 202, and the plurality of locking mechanisms 202 are sequentially arranged along the circumferential direction of the helmet shell 201. The replaceable lining 300 is provided with a plurality of detachable parts 302, and the plurality of detachable parts 302 are sequentially arranged along the circumferential direction of the replaceable lining 300. The plurality of locking mechanisms 202 and the plurality of detachable parts 302 of the same replaceable lining 300 are arranged in a one-to-one manner. The installation device 100 includes a plurality of installation members 103, and the plurality of detachable parts 302 of the same replaceable lining 300 are sleeved on the plurality of installation members 103 in a one-to-one manner.

[0206] In some specific embodiments, the replaceable inner lining 300 includes an inner lining 300 body and a plurality of detachable parts 302. The plurality of detachable parts 302 are arranged at intervals along the circumference of the inner lining 300 body. Each detachable part 302 is provided with a fixed connection part 3021 and a detachable connection part 3022. Each detachable part 302 is fixedly connected to the inner lining 300 body through the fixed connection part 3021, and all the detachable connection parts 3022 of the detachable parts 302 are used for detachably connecting to the helmet shell 201 of the helmet 200.

[0207] When a plurality of the locking mechanisms 202 provided in the above embodiments are provided on the inner wall of the helmet shell 201 of the helmet 200, the plurality of detachable connection parts 3022 of the plurality of detachable parts 302 are in one-to-one pressing docking with the plurality of locking mechanisms 202, and the plurality of mounting parts 1032 of the plurality of mounting parts 103 can be inserted into the plurality of locking mechanisms 202 one by one, and the inner lining 300 where the plurality of detachable parts 302 are located is mounted on the locking mechanism 202.

[0208] In some embodiments, the locking mechanism 202 includes two locking parts. The locking parts have a proximal end 2024 and a distal end 2025 that are opposite to each other in the first direction. The proximal end 2024 of any one locking part is arranged between the proximal end 2024 and the distal end 2025 of the other locking part in the first direction; wherein, at least one distal end 2025 is used for locking the replaceable inner lining 300.

[0209] The two locking parts are respectively a first locking part 2021 and a second locking part 2022. The locking mechanism 202 includes two elastic parts 2023. One elastic part 2023 is connected between the proximal end 2024 of the first locking part 2021 and the distal end 2025 of the second locking part 2022, and the other elastic part 2023 is connected between the distal end 2025 of the first locking part 2021 and the proximal end 2024 of the second locking part 2022. When the locking mechanism 202 is in the locking position, the two distal ends 2025 are in positions away from each other; when the locking mechanism 202 is in the unlocking position, the two distal ends 2025 are in positions close to each other.

[0210] In this embodiment, the two locking members are respectively a first locking member 2021 and a second locking member 2022. Both the first locking member 2021 and the second locking member 2022 are moving members, and both can move relative to each other. That is to say, the first locking member 2021 can move relative to the second locking member 2022 in the first direction, and the second locking member 2022 can also move relative to the first locking member 2021 in the first direction. For example, the first locking member 2021 can be directly slidably connected to any one of the following helmet shells 201, locking shells 204, and cages 203, and the second locking member 2022 can be directly slidably connected to any one of the following helmet shells 201, locking shells 204, and cages 203. Among them, preferably, the first locking member 2021 and the second locking member 2022 can be slidably connected to the same component. For example, both the first locking member 2021 and the second locking member 2022 are slidably connected to the cage 203.

[0211] For another example, the first locking member 2021 is directly slidably connected to any one of the helmet shell 201, the locking shell 204, and the cage 203, and the second locking member 2022 is slidably connected to the first locking member 2021. For example, the second locking member 2022 is slidably connected to the first locking member 2021 at the plane position where it contacts the first locking member 2021. For another example, the second locking member 2022 is directly slidably connected to any one of the helmet shell 201, the locking shell 204, and the cage 203, and the first locking member 2021 is slidably connected to the second locking member 2022. For example, the first locking member 2021 is slidably connected to the second locking member 2022 at the plane position where it contacts the second locking member 2022.

[0212] In this embodiment, the first locking member 2021 has a locking position and an unlocking position, and can be switched between the locking position and the unlocking position. The second locking member 2022 has a locking position and an unlocking position, and can be switched between the locking position and the unlocking position. The locking position of the first locking member 2021 and the locking position of the second locking member 2022 are symmetrically arranged about the central axis of the locking mechanism 202, and the unlocking position of the first locking member 2021 and the unlocking position of the second locking member 2022 are symmetrically arranged about the central axis of the locking mechanism 202.

[0213] The lifting mechanism 102 drives one of the helmet 200 and the mounting member 103 to lift relative to the other. The mounting portion 1032 enters between the two proximal ends 2024. The inner lining 300 and the locking mechanism 202 are squeezed and butted in the lifting direction, so as to force the detachable member 302 to act on the locking mechanism 202 and overcome the elastic force of the elastic member 2023, and drive the two proximal ends 2024 to be clamped with each other in the first direction, that is, the distal ends 2025 of the first locking member 2021 and the distal ends 2025 of the second locking member 2022 can approach each other in the first direction at the same time, and then switch from the unlocking position to the unlocking position. The inner lining 300 is mounted on the locking mechanism 202 and is locked under the elastic force of the elastic member 2023.

[0214] Since there are two elastic members 2023 in this embodiment, during the process that the second locking member 2022 switches from the locking position to the unlocking position in the first direction and the first locking member 2021 switches from the locking position to the unlocking position in the first direction, the proximal end 2024 of the second locking member 2022 and the distal end 2025 of the first locking member 2021 approach each other and simultaneously drive the elastic member 2023 connected between the two to store elastic force. The elastic member 2023 stores elastic force by being compressed. Synchronously, the distal end 2025 of the second locking member 2022 and the proximal end 2024 of the first locking member 2021 approach each other and synchronously drive the elastic member 2023 connected between the two to store elastic force. The elastic member 2023 also stores elastic force by being compressed. Under the action of the elastic forces of the two elastic members 2023, the second locking member 2022 switches from the unlocking position to the locking position and the first locking member 2021 synchronously switches from the unlocking position to the locking position.

[0215] In this embodiment, preferably, the structures of the first locking member 2021 and the second locking member 2022 are the same. The entire locking structure has a central axis located between the two proximal ends 2024, and the entire locking mechanism 202 is symmetrically arranged about the central axis.

[0216] In some embodiments, a pair of distal force-receiving sides 2025a facing away from each other are provided at the two distal ends 2025. The distal force-receiving sides 2025a are inclined relative to the first direction, and the pair of distal force-receiving sides 2025a are symmetrically arranged along the first direction. A pair of distal 2025 force-applying sides facing each other are provided at the two distal force-applying portions 30221. The distal 2025 force-applying sides are inclined relative to the first direction, and the pair of distal 2025 force-applying sides are symmetrically arranged along the first direction. The pair of distal 2025 force-applying sides are used to apply force to the pair of distal force-receiving sides 2025a and overcome the elastic force of the elastic member 2023.

[0217] During the automatic installation of the replaceable lining 300 onto the locking mechanism 202, multiple detachable parts 302 are aligned one by one with multiple locking mechanisms 202. A pair of distal force - applying parts 30221 in the detachable connecting part 3022 of the detachable part 302 apply force to two distal force - receiving sides 2025a of the two distal ends 2025 through a pair of distal 2025 force - applying sides. Since both the distal 2025 force - applying side and the distal force - receiving side 2025a are inclined, the two distal ends 2025 of the two locking parts can be forced to approach each other, switching from the locked position to the unlocked position.

[0218] Furthermore, a pair of opposite second latching structures 2025b are provided on the two distal force - applying parts 30221. The distal force - receiving side 2025a and the second latching structure 2025b on the same distal force - applying part 30221 are arranged in sequence along the lifting direction and are smoothly connected. The two second latching structures 2025b are latched to a pair of second latching structures 2025b under the elastic force of the elastic member 2023.

[0219] Since the distal 2025 force - applying side is smoothly connected to the first latching structure 30221b, and the distal force - receiving side 2025a and the second latching structure 2025b are smoothly connected, as the movement continues, a pair of distal force - receiving sides 2025a disengage from a pair of distal 2025 force - applying sides. The two locking parts move away from each other under the elastic force of the two elastic members 2023, and then the first latching structure 30221b and the second latching structure 2025b are successfully latched.

[0220] As Figures 31 to 36 shown, in the third application embodiment, the automatic disassembly device provided by the embodiment of the present application can also be used in combination with the automatic installation system of the helmet lining in a coaxial manner. The user can install on the side where the installation part 1032 is located, disassemble on the side where the disassembly part 1031 is located, or flip the installation part 1032 and the disassembly part 1031 through a flipping mechanism to complete disassembly and installation at the same position.

[0221] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included within the protection scope of the present application.
