Description

Technical Field

[0001] This application belongs to the technical field of shared devices, and more specifically, relates to a locking mechanism and a shared helmet. Background Art

[0002] With the convenience and diversification of modern transportation methods, shared electric bicycles, as a means of transportation that can be taken and used at any time, have been widely used 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 conform to the usage scenarios and conditions of shared electric bicycles.

[0003] However, the following technical problems exist 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 abandon using the shared electric bicycle because of the dirt, or users may choose to use the electric bicycle but abandon using the helmet, resulting in an increased probability of electric bicycle safety accidents.

[0005] Second, as a shared device, the lining in the shared helmet directly contacts the user's head. The hygiene of the lining is a safety consideration factor for users to choose a shared helmet and is also the main reason for users to abandon using the helmet.

[0006] Therefore, in order to solve the hygiene problem of shared electric bicycle helmets and improve the user's willingness and experience of use, there is an urgent need to provide a structure that can be equipped with a disposable lining on the helmet. Summary of the Invention

[0015] The locking mechanism includes two elastic members, one elastic member is connected between the proximal end of the first locking member and the distal end of the second locking member, and the other elastic member is connected between the distal end of the first locking member and the proximal end of the second locking member.

[0016] In some embodiments, among the two locking members, any one of the locking members is capable of moving relative to the other locking member in the first direction, and any one of the locking members has the locking position and the unlocking position and can be switched between the two.

[0017] In some embodiments, the two distal ends are provided with a pair of distal end force-receiving sides facing away from each other, the distal end force-receiving sides are inclined relative to the first direction, and the pair of distal end force-receiving sides are symmetrically arranged along the first direction;

[0019] In some embodiments, the two distal ends are provided with a pair of second latching structures facing away from each other, and the distal end force-receiving side and the second latching structure on the same distal end are arranged in sequence along the second direction and are smoothly connected;

[0020] When the pair of distal force-receiving sides disengage from the pair of distal force-applying sides, the two locking members move away from each other under the elastic force of the two elastic members, so that the two distals move away from each other and the pair of second latching structures are inserted into the first component.

[0021] In some embodiments, the two proximals are provided with a pair of proximally disposed force-receiving sides that are inclined relative to the first direction, and the pair of proximally disposed force-receiving sides are symmetrically disposed along the first direction;

[0027] The beneficial effects of the locking mechanism provided by the present application are as follows:

[0028] Compared with the prior art, the locking mechanism provided by the present application includes two locking members, the locking members have a proximal end and a distal end that are opposite to each other in the first direction, and the proximal end of any one locking member is arranged between the proximal end and the distal end of the other locking member in the first direction.

[0029] By cleverly setting the relative positional relationship between the two locking members in the locking mechanism, the two distal ends of the two locking members can be made to approach or move away from each other, thereby achieving a switch between the locked position and the unlocked position, completing the locking or unlocking of the first component, that is, the first component is fixed relative to the locking mechanism at the locked position, and the first component is disengaged from the locking mechanism at the unlocked position.

[0030] Applying the locking mechanism provided in this application to a shared helmet, the disposable replaceable inner lining can be locked by the locking mechanism, so that the replaceable inner lining is fixed in the helmet shell, and the replaceable inner lining can be disengaged from the locking mechanism when the locking mechanism is in the unlocked position, then the inner lining is detached from the shared helmet, and the replacement of the next inner lining can be carried out.

[0060] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more, unless otherwise specifically defined.

[0061] The locking mechanism 202, the replaceable inner lining 300, the replacement part 103, and the replacement device provided in the embodiments of this application will now be described.

[0062] Among them, in the following embodiments, the central axes of the locking mechanism 202, the replaceable inner lining 300, the replacement part 103, the helmet, and the replacement device all extend in the same direction, and the circumferential directions of the replaceable inner lining 300, the replacement part 103, the helmet, and the replacement device are all in the same direction. Among them, the following first direction may be the radial direction or the tangential direction of the helmet and the replaceable inner lining 300.

[0063] Please refer to Figures 1 to 18 As shown, the locking mechanism 202 provided in the embodiments of this application includes two locking members. Each locking member has 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 member is arranged between the proximal end 2024 and the distal end 2025 of the other locking member in the first direction; among them, 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; among them, when the locking member is in the locking position, the two distal ends 2025 are in a position away from each other; when the locking member is in the unlocking position, the two distal ends 2025 are in a position close to each other.

[0064] For the locking mechanism 202 provided in the embodiments of this application, by cleverly setting the relative position relationship of the two locking members in the locking mechanism 202, the two distal ends 2025 of the two locking members can be close to each other or away from each other, thereby realizing the switching between the locking position and the unlocking position, and completing the locking or unlocking of the first component, that is, the first component is fixed relative to the locking mechanism 202 in the locking position, and the first component is separated from the locking mechanism 202 in the unlocking position.

[0065] Applying the locking mechanism 202 provided in this application to a shared helmet, the disposable replaceable inner lining 300 can be locked by the locking mechanism 202, so that the replaceable inner lining 300 is fixed in the helmet shell, and the replaceable inner lining 300 can be separated from the locking mechanism 202 when the locking mechanism 202 is in the unlocking position, then the inner lining 300 is separated from the shared helmet, and the replacement of the next inner lining 300 can be carried out.

[0066] Among them, there are three ways in which at least one locking member can move relative to another locking member in the first direction. Among them, the two locking members are the first locking member 2021 and the second locking member 2022 respectively. The locking member located on the upper side is defined as the first locking member 2021, and the locking member located on the lower side is defined as the second locking member 2022. The locking mechanism 202 provided in the embodiment of the present application is applied to a shared helmet for illustration.

[0067] In some embodiments, the locking mechanism 202 can be detachably mounted on the inner wall of the helmet shell of the shared helmet through a cage 203. In some embodiments, the assembly composed of the locking mechanism 202 and the cage 203 can be arranged in a locking housing 204. The cage 203 is fixedly arranged relative to the locking housing 204, and the locking housing 204 is fixedly arranged relative to the inner wall of the helmet shell.

[0068] In the first embodiment, the first locking member 2021 is fixedly arranged relative to the helmet shell. For example, the first locking member 2021 can be directly fixedly connected to any one of the helmet shell, the locking housing 204, and the cage 203. The second locking member 2022 can move relative to the first locking member 2021 in the first direction. For example, the second locking member 2022 can be directly slidably connected to any one of the helmet shell, the locking housing 204, the cage 203, and the first locking member 2021. 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. During the switching process, the distal end 2025 of the second locking member 2022 can move closer to or away from the distal end 2025 of the first locking member 2021 in the first direction. When 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 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.

[0069] In the second embodiment, the second locking member 2022 is fixedly arranged relative to the helmet shell. For example, the second locking member 2022 can be directly fixedly connected to any one of the helmet shell, the locking shell 204, and the cage 203. The first locking member 2021 can move relative to the second locking member 2022 in the first direction. For example, the first locking member 2021 can be directly slidably connected to any one of the helmet shell, the locking shell 204, the cage 203, and the first locking member 2021. 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. During the switching process, the distal end 2025 of the first locking member 2021 can approach or move away from the distal end 2025 of the second locking member 2022 in the first direction. When the first locking member 2021 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, the two distal ends 2025 of the first locking member 2021 and the second locking member 2022 are in positions close to each other.

[0070] In the third embodiment, 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 helmet shell, the locking shell 204, and the cage 203, and the second locking member 2022 can be directly slidably connected to any one of the helmet shell, the locking shell 204, and the cage 203. 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.

[0071] For another example, the first locking member 2021 is directly slidably connected to any one of the helmet shell, 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 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, 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 in contact with the second locking member 2022.

[0072] In the above-described third 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. During the switching process, 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 simultaneously or move away from each other simultaneously in the first direction. 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.

[0073] 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. Of course, in other embodiments, based on the locking and unlocking principles of the locking mechanism 202 provided in the embodiments of the present application, the structures of the two locking members may be different.

[0074] In some embodiments, the locking mechanism 202 further includes at least one elastic member 2023, and the elastic member 2023 is connected between the proximal end 2024 of any one of the locking members and the distal end 2025 of the other locking member. The locking member is configured to switch from the locking position to the unlocking position under the action of an external force and simultaneously drive the elastic member 2023 to store elastic force, and switch from the unlocking position to the locking position under the action of the elastic force and maintain the locking.

[0075] In some embodiments, the locking mechanism 202 includes an elastic member 2023, and this design is applicable to the first embodiment and the second embodiment described above.

[0076] In the above-mentioned first embodiment, the first locking member 2021 is relatively fixedly arranged, the second locking member 2022 is slidably arranged, and the elastic member 2023 can be connected between the proximal end 2024 of the first locking member 2021 and the distal end 2025 of the second locking member 2022, or the elastic member 2023 can be connected between the proximal end 2024 of the second locking member 2022 and the distal end 2025 of the first locking member 2021. Correspondingly, during the process of the second locking member 2022 switching from the locking position to the unlocking position along the first direction, the distal end 2025 of the second locking member 2022 approaches the proximal end 2024 of the first locking member 2021 and synchronously drives the elastic member 2023 connected between the two to store elastic force. For example, the elastic member 2023 stores elastic force by being compressed, and under the action of the elastic force of the elastic member 2023, the second locking member 2022 switches from the unlocking position to the locking position and remains locked. Or, during the process of the second locking member 2022 switching from the locking position to the unlocking position along the first direction, the proximal end 2024 of the second locking member 2022 approaches the distal end 2025 of the first locking member 2021 and synchronously drives the elastic member 2023 connected between the two to store elastic force. For example, the elastic member 2023 stores elastic force by being compressed, and under the action of the elastic force of the elastic member 2023, the second locking member 2022 switches from the unlocking position to the locking position and remains locked.

[0077] In the above-mentioned second embodiment, the second locking member 2022 is relatively fixedly arranged, the first locking member 2021 is slidably arranged, and the elastic member 2023 can be connected between the proximal end 2024 of the first locking member 2021 and the distal end 2025 of the second locking member 2022, or the elastic member 2023 can be connected between the proximal end 2024 of the second locking member 2022 and the distal end 2025 of the first locking member 2021. Correspondingly, during the process of the first locking member 2021 switching from the locking position to the unlocking position along the first direction, the distal end 2025 of the first locking member 2021 approaches the proximal end 2024 of the second locking member 2022 and synchronously drives the elastic member 2023 connected between the two to store elastic force. For example, the elastic member 2023 stores elastic force by being compressed, and under the action of the elastic force of the elastic member 2023, the first locking member 2021 switches from the unlocking position to the locking position and remains locked. Or, during the process of the first locking member 2021 switching from the locking position to the unlocking position along the first direction, the proximal end 2024 of the first locking member 2021 approaches the distal end 2025 of the second locking member 2022 and synchronously drives the elastic member 2023 connected between the two to store elastic force. For example, the elastic member 2023 stores elastic force by being compressed, and under the action of the elastic force of the elastic member 2023, the first locking member 2021 switches from the unlocking position to the locking position and remains locked.

[0078] In some embodiments, the locking mechanism 202 includes two elastic members 2023, and this design is applicable to the above-mentioned first embodiment, second embodiment, and third embodiment. One elastic member 2023 can be 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 proximal end 2024 of the second locking member 2022 and the distal end 2025 of the first locking member 2021.

[0079] In the above-mentioned first embodiment, during the process of the second locking member 2022 switching from the locking position to the unlocking position in the first direction, the proximal end 2024 of the second locking member 2022 approaches the distal end 2025 of the first locking member 2021 and synchronously drives 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 approaches the proximal end 2024 of the first locking member 2021 and synchronously drives 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 unlocking position to the locking position and remains locked.

[0080] The switching principle of the above-mentioned second embodiment is the same as that of the above-mentioned first embodiment, and will not be elaborated here.

[0081] In the above-mentioned third embodiment, both the first locking member 2021 and the second locking member 2022 can move relative to each other in the first direction. The distal ends 2025 of the first locking member 2021 and the second locking member 2022 can approach each other or move away from each other simultaneously in the first direction. 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 a position 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 a position close to each other.

[0082] During the process that the second locking member 2022 switches from the locking position to the unlocking position along the first direction and the first locking member 2021 switches from the locking position to the unlocking 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 unlocking position to the locking position and the first locking member 2021 synchronously switches from the unlocking position to the locking position. The first locking member 2021 and the second locking member 2022 are both locked under the action of the two elastic members 2023.

[0083] In a preferred embodiment of the present application, 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.

[0084] By using two elastic members 2023, no matter which of the above-mentioned first embodiment, second embodiment or third embodiment is adopted, the locking mechanism 202 can be in a relatively balanced state, which is more conducive to the stable switching of the first locking member 2021 and / or the second locking member 2022 between the unlocking position and the locking mechanism 202, and stably maintaining at the locking position.

[0085] Furthermore, based on the use of two elastic members 2023, in a preferred embodiment of the present application, among the two locking members, any one of the locking members can move relative to the other locking member in the first direction. Any one of the locking members has a locking position and an unlocking position and can switch between the two. That is to say, both the first locking member 2021 and the second locking member 2022 can move relative to each other in the first direction, making the design of the locking mechanism 202 more flexible and symmetrical, more conducive to the stable unlocking and stable locking of the locking mechanism 202, and more stably maintaining at the locking position.

[0086] Among them, at least one distal end 2025 of the two locking members is used to lock the first component. When the locking mechanism 202 provided in the embodiment of the present application is used for a shared helmet, the first component can be a replaceable inner lining 300. One of a groove structure or a protrusion structure can be provided on the distal end 2025. Correspondingly, the other of the protrusion structure or the groove structure can be provided on the replaceable inner lining 300. The distal end 2025 and the replaceable inner lining 300 can be detachably connected through the groove structure and the protrusion structure.

[0087] For example, in the above first embodiment, the second locking member 2022 can move relative to the first locking member 2021 in the first direction, and the distal end 2025 of the second locking member 2022 can lock or unlock the replaceable inner lining 300. A plurality of locking mechanisms 202 can be provided near the wearing opening of the shared helmet. Multi-point locking can be achieved through the plurality of distal ends 2025 of the plurality of second locking members 2022 in the plurality of locking mechanisms 202, so that the replaceable inner lining 300 can be stably fixed in the helmet.

[0088] For another example, in the above first embodiment, the second locking member 2022 can move relative to the first locking member 2021 in the first direction, and both the distal end 2025 of the second locking member 2022 and the distal end 2025 of the first locking member 2021 can lock or unlock the replaceable inner lining 300. A plurality of locking mechanisms 202 can be provided near the wearing opening of the shared helmet. The two distal ends 2025 of the two locking members in one locking mechanism 202 can achieve locking simultaneously, so that the replaceable inner lining 300 can be stably fixed in the helmet.

[0089] The locking principles of the above second embodiment and the above first embodiment are the same, and will not be elaborated here.

[0090] In the preferred embodiment of the present application, the above third embodiment is adopted. Both the first locking member 2021 and the second locking member 2022 can move relative to each other in the first direction. The distal ends 2025 of the first locking member 2021 and the second locking member 2022 can simultaneously approach each other or simultaneously move away from each other in the first direction, and both of the two distal ends 2025 are used to lock the replaceable inner lining 300.

[0091] The replaceable inner lining 300 provided by the embodiment of the present application includes an inner lining 300 body and a plurality of detachable parts 302, and 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. When a plurality of locking mechanisms 202 provided by the above embodiment are provided on the inner wall of the helmet shell, the plurality of detachable parts 302 and the plurality of locking mechanisms 202 are arranged in a one-to-one manner. The following takes the first component as the replaceable inner lining 300 as an example for illustration.

[0092] Based on the above third embodiment, as Figures 1 to 8 shown, in some embodiments, two distal ends 2025 are provided with a pair of distal end force-receiving sides 2025a facing away from each other, and the distal end force-receiving sides 2025a are inclined relative to the first direction, and the pair of distal end force-receiving sides 2025a are symmetrically arranged along the first direction. The pair of distal end force-receiving sides 2025a are configured to contact a pair of distal end force-applying sides 30221a of the first component when the locking mechanism 202 and the first component move relative to each other in the second direction, and a pair of first external forces are provided by the pair of distal end force-applying sides 30221a, and the pair of first external forces drive the two locking members to move towards each other so that the two distal ends 2025 approach each other; wherein, the first direction and the second direction are perpendicular.

[0093] Furthermore, in some embodiments, two distal ends 2025 are provided with a pair of second clamping structures 2025b facing away from each other, and the distal end force-receiving sides 2025a and the second clamping structures 2025b on the same distal end 2025 are arranged in sequence and smoothly connected along the second direction. When the pair of distal end force-receiving sides 2025a are separated from the pair of distal end force-applying sides 30221a, the two locking members move away from each other under the elastic force of the two elastic members 2023 so that the two distal ends 2025 move away from each other and the pair of second clamping structures 2025b are clamped into the first component.

[0094] Correspondingly, by way of example, in some embodiments, the above detachable connection part 3022 includes a pair of distal end force-applying parts 30221 arranged oppositely, and a pair of first clamping structures 30221b are provided on the pair of distal end force-applying parts 30221, and the first clamping structures 30221b are used for detachably clamping with the pair of second clamping structures 2025b described above.

[0095] In some embodiments, a pair of opposite distal force - applying sides 30221a are provided on a pair of distal force - applying portions 30221. The pair of distal force - applying sides 30221a and a pair of first latching structures 30221b are arranged in sequence and smoothly connected along the thickness direction of the inner lining 300 body. The pair of distal force - applying sides 30221a are inclined relative to the thickness direction of the inner lining 300 body and are used to guide a pair of second latching structures 2025b into the pair of first latching structures 30221b.

[0096] When manually or automatically installing the replaceable inner lining 300 onto the locking mechanism 202, aligning the plurality of detachable parts 302 with the plurality of locking mechanisms 202 one - to - one. The helmet shell can be manually or automatically operated to synchronously drive the plurality of locking mechanisms 202 to move towards the plurality of detachable parts 302 along the second direction, or the replaceable inner lining 300 can be manually or automatically operated to drive the plurality of detachable parts 302 to move towards the plurality of locking mechanisms 202 along the second direction. During the movement, a pair of distal force - applying portions 30221 of the detachable connection portion 3022 in the detachable part 302 apply force to two distal force - receiving sides 2025a of the two distals 2025 through a pair of distal force - applying sides 30221a. Since both the distal force - applying side 30221a and the distal force - receiving side 2025a are inclined, the two distals 2025 of the two locking members can be forced to approach each other, switching from the locked position to the unlocked position.

[0097] Furthermore, since the distal force - applying side 30221a 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, the pair of distal force - receiving sides 2025a disengage from the pair of distal force - applying sides 30221a. Under the elastic force of the two elastic members 2023, the two locking members move away from each other respectively, and then the first latching structure 30221b and the second latching structure 2025b are smoothly latched.

[0098] Among them, one of the first latching structure 30221b and the second latching structure 2025b can be a groove structure, and the other can be a protrusion structure. Exemplarily, in some specific embodiments, the first latching structure 30221b can be a groove structure, specifically a notch structure penetrating the thickness of the detachable part 302. The second latching structure 2025b can be a protrusion structure, and its contour can just be latched into the notch structure.

[0099] In summary, based on the locking mechanism 202 provided in the above-described third embodiment, through the mutual adaptation and mutual sliding guidance between the distal force-applying side 30221a and the distal force-receiving side 2025a, combined with the mutual adaptation and detachable clamping of the first clamping structure 30221b and the second clamping structure 2025b, the first component can be locked on the locking mechanism 202, and the locking mechanism 202 can be provided on the shared helmet, thereby realizing the installation of the inner lining 300 of the shared helmet.

[0100] In other solutions, based on the locking mechanism 202 provided in the above-described first and second embodiments, the installation of the first component can also be completed.

[0101] For example, based on the locking mechanism 202 provided in the above-described first embodiment, the second locking member 2022 can move relative to the first locking member 2021 in the first direction, and the distal end 2025 of the second locking member 2022 can lock or unlock the replaceable inner lining 300. Specifically, the distal end 2025 of the second locking member 2022 is provided with a distal force-receiving side 2025a facing away from the first locking member 2021, and the distal force-receiving side 2025a is inclined relative to the first direction. The distal end 2025 of the second locking member 2022 is also provided with a second clamping structure 2025b, and the distal force-receiving side 2025a and the second clamping structure 2025b are arranged in sequence and smoothly connected along the second direction. Correspondingly, by way of example, the detachable connecting portion 3022 has a distal force-applying portion 30221, and the distal force-applying portion 30221 is provided with a first clamping structure 30221b and a distal force-applying side 30221a. The distal force-applying side 30221a and the first clamping structure 30221b are arranged in sequence and smoothly communicated along the thickness direction of the inner lining 300 body. Through the mutual adaptation and mutual sliding guidance between the distal force-applying side 30221a and the distal force-receiving side 2025a, combined with the mutual adaptation and detachable clamping of the first clamping structure 30221b and the second clamping structure 2025b, the second locking member 2022 is forced to switch from the locking position to the unlocking position, and the replaceable inner lining 300 can be detachably clamped.

[0102] The principles of sliding guidance and clamping in the above-described second embodiment and the above-described first embodiment are the same, and will not be elaborated here.

[0103] Furthermore, compared with the two symmetrically arranged distal ends 2025 of the two locking members and the two symmetrically arranged distal force-applying portions 30221 of the first component provided in the third embodiment, based on the same principles of sliding guidance and clamping, a pair of translationally arranged distal ends 2025 and a pair of translationally arranged distal force-applying portions 30221 can be provided.

[0104] More specifically, the distal end 2025 on the right side of the first locking member 2021 and the distal end applying force portion 30221 on the right side of the replaceable inner lining 300 are cancelled. The distal end 2025 on the left side of the second locking member 2022 is translated to the right side, and the distal end applying force portion 30221 on the left side of the replaceable inner lining 300 is translated to the right side.

[0105] Based on the locking principle of the locking mechanism 202 provided in the above first embodiment, the replaceable inner lining 300 is manually or automatically installed. The replaceable inner lining 300 squeezes the second locking member 2022 along the second direction, and the second locking member 2022 moves from the left side to the right side, that is, moves from the locking position to the unlocking position. When the first engaging structure 30221b and the second engaging structure 2025b are engaged with each other, the second locking member 2022 moves from the right side to the right side under the action of the elastic member 2023, that is, moves from the unlocking position to the locking position, and a pair of translationally arranged distal ends 2025 and a pair of translationally arranged distal end applying force portions 30221 are fully adapted in place.

[0106] The above-mentioned pair of translationally arranged distal ends 2025 and a pair of translationally arranged distal end applying force portions 30221 are also applicable to the locking principle of the locking mechanism 202 provided in the above second embodiment, and will not be elaborated here.

[0107] It should be noted that the application devices of the locking mechanism 202 include but are not limited to shared helmets, and can be non-shared helmets or other devices that need to replace components. The components that can be locked by the locking mechanism 202 include but are not limited to the replaceable inner lining 300.

[0108] It should be noted that as an exemplary replaceable inner lining 300 can be manually or automatically replaced onto the locking mechanism 202. For example, the helmet and the replaceable inner lining 300 provided with the locking mechanism 202 can be manually operated to squeeze each other along the second direction and finally be engaged. Or, an automatic method can be adopted, using an automatic device to drive the helmet to actively approach the replaceable inner lining 300 to complete the replacement, or using an automatic device to drive the replaceable inner lining 300 to approach the locking mechanism 202 of the helmet to complete the replacement.

[0109] It should be noted that the locking mechanism 202 provided in the embodiment of the present application is applied to a helmet. In order to ensure the stability of the replaceable inner lining 300 in the helmet, multiple locking mechanisms 202 are provided in the helmet. In other embodiments, the specific application quantity of the locking mechanism 202 can be specifically selected according to specific requirements, and the embodiment of the present application does not make specific limitations on this.

[0110] Based on the above-mentioned third embodiment, in some embodiments, two proximal ends 2024 are provided with a pair of proximal force-receiving sides 2024a opposite to each other. 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.

[0111] When the user unlocks the locking mechanism 202 to separate the first component from the locking mechanism 202, the user can manually contact the pair of proximal force-receiving sides 2024a, and drive the two proximal ends 2024 to move away from each other through the pair of proximal force-receiving sides 2024a. Then, the two distal ends 2025 of the two locking members approach each other, and the two locking members are simultaneously switched from the locked position to the unlocked position, and the first component is unlocked and can be separated from the locking mechanism 202. That is to say, when the first component is the replaceable inner lining 300, the user can manually replace the replaceable inner lining 300 onto the helmet or manually remove the replaceable inner lining 300 from the helmet. In this way, the user can complete the replacement of the inner lining 300 entirely manually.

[0112] In other solutions, based on the locking mechanism 202 provided in the above-mentioned first embodiment and second embodiment, the first component can also be manually unlocked.

[0113] For example, based on the locking mechanism 202 provided in the above-mentioned first embodiment, the second locking member 2022 can move relative to the first locking member 2021 in the first direction. A proximal force-receiving side 2024a is provided on the proximal end 2024 of the second locking member 2022. The user drives the second locking member 2022 to move relative to the fixed first locking member 2021 by contacting the one proximal force-receiving side 2024a. The second locking member 2022 is switched from the locked position to the unlocked position, and the first component is unlocked and can be separated from the locking mechanism 202.

[0114] The manual unlocking principle of the above-mentioned second embodiment and the above-mentioned first embodiment is the same, and will not be elaborated here.

[0115] Based on the above-mentioned third embodiment, the pair of proximal force-receiving sides 2024a are configured to contact a pair of proximal force-applying sides 1031b of the second component when the locking mechanism 202 and the second component move relative to each other in the second direction, and a pair of second external forces are provided by the pair of proximal force-applying sides 1031b. The pair of second external forces drive the two locking members to move towards each other, so that the two distal ends 2025 approach each other; wherein, the first direction and the second direction are perpendicular.

[0116] In this way, the user can use an operating tool or an automatic replacement device to unlock the locking mechanism 202. For example, the user can use the replacement part 103 as an operating tool to unlock the first component by himself, or use the replacement part 103 in the automatic replacement device to automatically unlock the first component.

[0117] Based on the above-described third embodiment, the replacement part 103 provided in the embodiments of the present application has a disassembly part 1031. On both sides of the disassembly part 1031 along the first direction, there are two proximal force application parts 1031a. The two proximal force application parts 1031a have two proximal force application sides 1031b facing away from each other. The two proximal force application sides 1031b are inclined and symmetrically arranged with respect to the first direction. The proximal force application side 1031b is adapted to the proximal force receiving side 2024a of the locking mechanism 202, and is used to provide a first external force to the proximal force receiving side 2024a when moving towards the locking mechanism 202 along the second direction. By the first external force, the locking mechanism 202 is driven to switch from the locked position to the unlocked position, so as to disassemble the used replaceable inner liner 300 from the locking mechanism 202.

[0118] Based on the locking mechanism 202 provided in the above-described first embodiment and second embodiment, the first component can also be unlocked by using the corresponding replacement part 103 and the corresponding automatic replacement device.

[0119] For example, based on the locking mechanism 202 provided in the first embodiment, the second locking member 2022 can move relative to the first locking member 2021 in the first direction, and a proximal force receiving side 2024a is provided on the proximal end 2024 of the second locking member 2022. Correspondingly, a proximal force application part 1031a is provided on one side of the disassembly part 1031 along its radial direction. The proximal force application side 1031b is inclined with respect to the first direction. The proximal force application part 1031a drives the second locking member 2022 to move relative to the first locking member 2021 from the locked position to the unlocked position by providing an external force through contacting the proximal force receiving side 2024a.

[0120] The principle of tool unlocking or automatic unlocking of the locking mechanism 202 provided in the second embodiment above is the same as the unlocking principle of the first embodiment above, and will not be elaborated here.

[0121] As a preferred embodiment of the locking mechanism 202 of the present application, the locking members are in a ring shape, and two semi-ring portions where the two proximal ends 2024 of the two locking members are located are stacked along the second direction, and a threading space 2026 is surrounded by the two semi-ring portions. The threading space 2026 is used for movably threading the second component to provide a second external force for the second component.

[0122] Among them, the replacement part 103 can enter or exit the threading space 2026 during the movement along the second direction. The design of the threading space 2026 is to enable the replacement part 103 to be more accurately aligned with the locking structure, so as to ensure that the proximal force receiving side 2024a on the disassembly part 1031 thereof and the proximal force receiving side 2024a on the proximal end 2024 of the locking member are accurately docked and the force is applied.

[0123] In other embodiments, the structures of the first locking member 2021 and the second locking member 2022 may be the same or different. The structure of the locking member may be an open-loop structure. The first locking member 2021 and the second locking member 2022 can be partially stacked, and the two distal ends 2025 are located on both sides of the overlapping part along the first direction. The embodiments of the present application do not specifically limit the specific structure of the locking member. Any structure that can implement the locking principle of the locking mechanism 202 provided by the embodiments of the present application is within the protection scope of the present application.

[0124] In addition, it should be noted that for the locking mechanism 202 provided by the embodiments of the present application, the first component is locked by the distal end 2025, and the proximal end 2024 is used as the power driving part. However, based on the cooperative setting of the locking mechanism 202, the proximal end 2024 can also be used to lock the first component, and the distal end 2025 is used as the power driving part.

[0125] For example, 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. Among them, when the locking member is in the locking position, the two proximal ends 2024 are in a position close to each other, and the first component is locked here; when the locking member is in the unlocking position, the two proximal ends 2024 are in a position far from each other, and the first component is unlocked at this time. The locking and unlocking principles are only different based on the functional switching of the proximal end 2024 and the distal end 2025, but the cooperation mode of the two locking members is the same as that of the first embodiment, the second embodiment and the third embodiment. This solution also belongs to the design concept of the present application and is within the protection scope of the present application.

[0126] As a preferred embodiment of the locking mechanism 202 of the present application, the locking mechanism 202 further includes a cage 203. The cage 203 is provided with a first slideway 2031 and a second slideway 2032. The first slideway 2031 and the second slideway 2032 are arranged in sequence along the first direction, and both the first slideway 2031 and the second slideway 2032 extend along 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. That is, the best implementation of the above-mentioned third embodiment is that the first locking member 2021 and the second locking member 2022 are respectively slidably connected to the cage 203.

[0127] 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.

[0128] 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.

[0129] 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. 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.

[0130] Of course, in other embodiments, the setting of the locking housing 204 may be cancelled, and the cage 203 may be directly fixedly connected to the inner wall of the helmet shell.

[0131] Based on the locking mechanism 202 provided by the embodiments of the present application, the embodiments of the present application further provide a shared helmet. The helmet includes a helmet shell and a first component, and the locking mechanism 202 as described above. Among them, the first component is a replaceable inner lining 300. The locking mechanism 202 is installed on the inner wall of the helmet shell. When the locking member is in the locked position, the two distal ends 2025 thereof are in positions away from each other, and the replaceable inner lining 300 is in a locked state relative to the helmet shell; when the locking member is in the unlocked position, the two distal ends 2025 thereof are in positions close to each other, and the replaceable inner lining 300 is in a disassembled state relative to the helmet shell.

[0132] Applying the locking mechanism 202 provided in the embodiments of the present application to a shared helmet, the disposable replaceable lining 300 can be locked by the locking mechanism 202, so that the replaceable lining 300 is fixed in the helmet shell. And the replaceable lining 300 can be detached from the locking mechanism 202 when the locking mechanism 202 is in the unlocked position, then the lining 300 is detached from the shared helmet, and the next lining 300 can be replaced.

[0133] The following provides a detailed description of the replaceable lining 300 provided in the embodiments of the present application.

[0134] As Figures 9 to 11 shown, the replaceable lining 300 provided in the embodiments of the present application includes a lining 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 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 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.

[0135] For the replaceable lining 300 provided in the embodiments of the present application, all the detachable connection parts 3022 of the detachable parts 302 are used for detachably connecting to the helmet shell. By providing a plurality of detachable parts 302 on the periphery of the lining 300 body, the replaceable lining 300 can be replaced as a disposable consumable on the helmet, and the detachable parts 302 can be manually or automatically assembled near the wearing opening of the helmet.

[0136] The replaceable lining 300 provided in the embodiments of the present application can be used as a disposable consumable and can be extracted and replaced with the number of times the shared helmet is used. Each time the user uses a shared electric vehicle, the storage device or automatic replacement device of the replaceable lining 300 can be synchronously opened through an identification code, and the lining 300 can be manually extracted for replacement, or the lining 300 of the helmet can be automatically replaced by the automatic replacement device. When the replaceable lining 300 is in the storage state, it is not exposed to the outdoor environment. Each time the user can extract or replace a new lining 300 according to the need, which ensures the hygienic safety of the helmet lining 300 and can improve the usage probability and usage safety of the electric vehicle.

[0137] For the replaceable lining 300 provided in the embodiments of the present application, the user can purchase and store it by himself / herself and can carry and replace it by himself / herself when using the shared helmet. Or, it is purchased and stored by the shared device provider, and the user extracts and uses it by scanning the identification code. Or, the replaceable lining 300 can be stored in the automatic replacement device, replaced on the helmet by the automatic replacement device, and replenished regularly by the provider.

[0138] The replaceable inner lining 300 provided by the embodiments of the present application, when multiple replaceable inner linings 300 are in a stacked and stored state, the user can directly place the helmet on the uppermost replaceable inner lining 300 among the multiple replaceable inner linings 300, and by pressing down the helmet, the replaceable inner lining 300 can be replaced on the helmet in a snap-fit manner. For example, the inner lining 300 provided by the embodiments of the present application can be snap-connected to the locking mechanism 202 through the detachable connection part 3022 in the detachable part 302. Of course, the replaceable inner lining 300 provided by the embodiments of the present application is not limited to the snap-fit manner of the detachable connection part 3022 and the locking mechanism 202 provided by the embodiments of the present application.

[0139] In some embodiments, the body of the inner lining 300 provided by the embodiments of the present application is a flexible material piece and has a sheet structure. The body of the inner lining 300 has a folded state and an unfolded state; wherein, when the body of the inner lining 300 is in the folded state, the body of the inner lining 300 is planar; when the body of the inner lining 300 is in the unfolded state, the body of the inner lining 300 is adapted to the inner wall of the helmet shell. The body of the inner lining 300 includes at least one folding part, and the folding part includes at least an adjacent first folding layer and a second folding layer. When the first folding layer and the second folding layer are overlapped, the body of the inner lining 300 is in the folded state, and when the first folding layer and the second folding layer are unfolded, the body of the inner lining 300 is in the unfolded state.

[0140] The body of the inner lining 300 is a flexible material piece and has a sheet structure, and its state can be changed according to specific requirements. When the body of the inner lining 300 is in the folded state, the body of the inner lining 300 is planar, so that multiple bodies of the inner lining 300 can be stacked and stored, occupying a smaller space and facilitating sequential extraction, installation and use one by one. When the body of the inner lining 300 is in the unfolded state, the body of the inner lining 300 is adapted to the inner wall of the helmet shell, which is convenient for the user to wear the helmet and plays a role in isolating the helmet.

[0141] Among them, the detachable part 302 can be a flexible rope, a magic tape or a rigid detachable part 302. For example, the detachable part 302 can be a flexible rope, and a through-hole is designed at the attachment of the wearing opening of the helmet shell. The flexible rope passes through the through-hole and is knotted, or the adjacent flexible ropes are fixedly connected, so that the inner lining 300 can be fixed relative to the helmet shell. For example, the detachable part 302 can be the hook surface or the loop surface of the magic tape, and the loop surface or the hook surface is designed at the attachment of the wearing opening of the helmet shell. Through the fitting of the hook surface and the loop surface, the inner lining 300 can be fixed relative to the helmet shell. For example, the detachable part 302 is a rigid detachable part 302, and the rigid detachable part 302 is connected to the helmet shell by a detachable snap-fit method.

[0142] In some embodiments, the detachable member 302 is a rigid detachable member 302, which may be a plastic member with a certain hardness. The detachable member 302 includes a first piece and a second piece. The first piece and the second piece are stacked along the thickness direction of the inner lining 300 body. The peripheral edge of the inner lining 300 body is clamped between the first piece and the second piece. A detachable connection portion 3022 is provided on the side of the first piece facing away from the second piece or the side of the second piece facing away from the first piece.

[0143] The detachable member 302 in the form of a piece can reduce the manufacturing cost and thus the cost of the replaceable inner lining 300. Moreover, the clamping method is more conducive to the convenient positioning of the inner lining 300 body, making the height positions of multiple detachable members 302 relative to the plane where the inner lining 300 is located more consistent, which is beneficial to the synchronous automatic installation of multiple detachable members 302 and the helmet shell.

[0144] In some specific embodiments, the first piece and the second piece are bonded. Or, the first piece and the second piece are detachably clamped. Or, a clamping groove is formed between the radially inward side of the first piece and the radially inward side of the second piece, and the peripheral edge of the inner lining 300 body is clamped in the clamping groove. The radially outward side of the first piece and the radially outward side of the second piece are integrally connected. The setting method of the first piece and the second piece can be selected according to the material and cost of the inner lining 300 body.

[0145] Corresponding to the locking mechanism 202 provided in the above third embodiment, in some embodiments, the detachable connection portion 3022 includes a pair of distal end applying force portions 30221 arranged oppositely. A pair of first clamping structures 30221b are provided on the pair of distal end applying force portions 30221, and the first clamping structures 30221b are used for detachably clamping with a pair of second clamping structures 2025b on the helmet shell. In some embodiments, a pair of distal end applying force sides 30221a are provided on the pair of distal end applying force portions 30221. The pair of distal end applying force sides 30221a and the pair of first clamping structures 30221b are arranged in sequence and smoothly connected along the thickness direction of the inner lining 300 body. The pair of distal end applying force sides 30221a are inclined relative to the thickness direction and are used to guide the pair of second clamping structures 2025b into the pair of first clamping structures 30221b.

[0146] In other embodiments, corresponding to the locking mechanism 202 provided in the above-mentioned first embodiment and second embodiment, the detachable connection portion 3022 has a distal end applying force portion 30221, and the distal end applying force portion 30221 is provided with a first clamping structure 30221b and a distal end applying force side 30221a. The distal end applying force side 30221a and the first clamping structure 30221b are arranged in sequence and smoothly connected along the thickness direction of the inner liner 300 body. Through the mutual adaptation and mutual sliding guide between the distal end applying force side 30221a and the distal end receiving force side 2025a, combined with the mutual adaptation and detachable clamping between the first clamping structure 30221b and the second clamping structure 2025b, the second locking member 2022 is forced to switch from the locking position to the unlocking position, and the replaceable inner liner 300 is detachably clamped.

[0147] Corresponding to the locking mechanism 202 provided in the above-mentioned third embodiment, a pair of distal end applying force sides 30221a are symmetrically arranged along the tangential direction or radial direction of the inner liner 300 body. A pair of first clamping structures 30221b are symmetrically arranged along the tangential direction or radial direction of the inner liner 300 body. That is to say, in the embodiment of the locking mechanism 202, when the locking mechanism 202 is installed in the helmet or the replaceable inner liner 300 corresponds to the locking mechanism 202, the first direction may be the tangential direction at the positioning point of the locking mechanism 202 in the circumferential direction of the helmet or the inner liner 300, or the radial direction of the helmet and the inner liner 300.

[0148] A pair of distal end receiving force sides 2025a are symmetrically arranged along the tangential direction of the point where the locking mechanism 202 is located. In other embodiments, a pair of distal end receiving force sides 2025a may be symmetrically arranged along the radial direction of the inner liner 300, and this radial direction is perpendicular to the tangential direction.

[0149] Corresponding to the locking mechanism 202 provided in the above-mentioned first embodiment and second embodiment, a pair of distal end applying force sides 30221a are arranged in translation along the tangential direction or radial direction of the inner liner 300 body. A pair of first clamping structures 30221b are arranged in translation along the tangential direction or radial direction of the inner liner 300 body. That is, one distal end applying force side 30221a is translated along the tangential direction or radial direction of the inner liner 300 body to the position of the other distal end applying force side 30221a, and the two distal end applying force sides 30221a are completely the same.

[0150] For example, based on the locking principle of the locking mechanism 202 provided in the first embodiment, the replaceable liner 300 is manually or automatically installed, the replaceable liner 300 presses the second locking member 2022 along the second direction, and the second locking member 2022 moves from the left side to the right side, that is, from the locked position to the unlocked position. When the first clamping structure 30221b and the second clamping structure 2025b are mutually engaged, the second locking member 2022 moves from the right side to the right side under the action of the elastic member 2023, that is, from the unlocked position to the locked position, and a pair of translationally arranged distal ends 2025 and a pair of translationally arranged distal end force-applying parts 30221 are fully adapted to the position.

[0151] Corresponding to the locking mechanism 202 provided in the third embodiment described above, in some embodiments, a through hole 30222 is provided at the center of the detachable connecting portion 3022, and the through hole 30222 can be arranged opposite to the through space 2026 of the locking mechanism 202 described above. The hole edge of the through hole 30222 includes two first expansion portions 30222a and two second expansion portions 30222b arranged opposite to each other, the distance between the first expansion portion 30222a and the hole axis of the through hole 30222 is greater than the distance between the second expansion portion 30222b and the hole axis, and the first expansion portion 30222a and the second expansion portion 30222b are arranged alternately along the circumference of the through hole 30222; wherein, the two distal force-applying portions 30221 are arranged on the outside of the two first expansion portions 30222a. wherein, the first expansion portion 30222a and the second expansion portion 30222b are both semicircular.

[0152] Among them, the penetration hole 30222 and the penetration space 2026 are both used to penetrate the disassembly part 1031 or the installation part 1032 of the replacement part 103.

[0153] Among them, corresponding to the locking mechanism 202 and the replaceable liner 300 provided in the above-mentioned third embodiment, the disassembly portion 1031 of the replacement part 103 provided in the embodiment of the present application is provided with two proximal force-applying portions 1031a on both sides along the above-mentioned first direction, and the two proximal force-applying portions 1031a have two proximal force-applying sides 1031b that are opposite to each other, and the two proximal force-applying sides 1031b are inclined relative to the first direction and are symmetrically arranged.

[0154] Among them, the maximum distance between the two first extension parts 30222a along the first direction is greater than the maximum distance between the two proximal force-applying parts 1031a along the first direction, so as to allow the two proximal force-applying parts 1031a to smoothly pass through the space between the two first extension parts 30222a, contact with the two proximal force-bearing sides 2024a of the two proximal ends 2024 on the two locking members and apply the above-mentioned second external force, and allow the two proximal force-applying parts 1031a to smoothly exit the penetration hole 30222 and the penetration space 2026.

[0155] Furthermore, a separating portion 1031c is provided on the disassembly portion 1031 in a direction perpendicular to the first direction. The separating portion 1031c is provided with an inclined surface. In other words, the separating portion 1031c and the proximal end biasing portion 1031a are arranged at intervals along the circumferential direction of the disassembly portion 1031. The separating portion 1031c includes a main body portion a and a telescopic portion b. The main body portion a is connected to the disassembly portion 1031 through the telescopic portion b, so that the separating portion 1031c can telescopically move relative to the disassembly portion 1031 in a direction perpendicular to the first direction.

[0156] Among them, the separating portion 1031c has two design schemes. The separating portion 1031c can be a single-sided arrangement or a bilateral symmetric arrangement of two. Both of these two design schemes are applicable to the detachable connection portion 3022 described above.

[0157] Furthermore, the distance from the edge of the second expansion portion 30222b to the central axis of the through hole 30222 is less than the maximum distance from the separating portion 1031c to the central axis of the disassembly portion 1031 when the separating portion 1031c is in the extended state, and greater than the maximum distance from the separating portion 1031c to the central axis of the disassembly portion 1031 when the separating portion 1031c is in the contracted state. The natural state of the second expansion portion 30222b is the extended state. Due to the setting of the inclined surface, the second expansion portion 30222b can prevent the separating portion 1031c in the extended state from passing through the through hole 30222 when the replacement part 103 exits the through hole 30222, and can squeeze the separating portion 1031c into the contracted state and allow the separating portion 1031c to pass through the through hole 30222 when the replacement part 103 enters the through hole 30222.

[0158] Specifically, during the process of the disassembly portion 1031 entering the through hole 30222 and the through space 2026, the separating portion 1031c is squeezed by the second expansion portion 30222b and switches from the extended state to the contracted state. After the separating portion 1031c passes through the through hole 30222 and enters the through space 2026, the squeezing force of the second expansion portion 30222b on the separating portion 1031c disappears, and the separating portion 1031c naturally switches to the extended state. Synchronously, the two proximal end biasing 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 lining 300 is disassembled. During the process of the disassembly portion 1031 exiting the through space 2026 and the through hole 30222, the separating portion 1031c separates the replaceable lining 300.

[0159] Among them, corresponding to the two design schemes of the detaching part 1031c, the second extension part 30222b can also be set to one or two corresponding to the detaching part 1031c. When the second extension part 30222b is two and the detaching part 1031c is two, the two detaching parts 1031c and the two second extension parts 30222b are arranged in one-to-one correspondence.

[0160] Corresponding to the locking mechanism 202 provided in the above first embodiment and second embodiment, since only a second external force needs to be applied to one proximal end 2024 through the proximal end applying side 1031b of one proximal end applying part 1031a, one proximal end applying part 1031a can be correspondingly provided. On this basis, one or two detaching parts 1031c can be provided.

[0161] It should be noted that based on the replaceable inner lining 300 provided in the embodiments of the present application, when the detachable part 302 is a rigid detachable part 302, its structural form has various designs, and the corresponding locking mechanism 202 also has various forms, not limited to the structure of the detachable connection part 3022 provided in the embodiments of the present application and the locking mechanism 202 provided in the embodiments of the present application. Based on multiple detachable parts 302, the replaceable inner lining 300 can be directly snapped onto the helmet through a groove structure and a protrusion structure, or indirectly snapped onto the helmet through other snap parts.

[0162] Based on the replaceable inner lining 300 provided in the embodiments of the present application, the embodiments of the present application also provide a shared helmet, which includes a helmet shell and the replaceable inner lining 300 as above. The helmet shell has a wearing opening, and the edge of the replaceable inner lining 300 and the edge of the wearing opening are detachably connected directly or indirectly through a detachable connection part 3022.

[0163] As Figures 12 to 17 As shown, the replacement part 103 provided in the embodiments of the present application includes a disassembling part 1031, an installing part 1032, and a storage part; the disassembling part 1031 and the installing part 1032 are arranged at intervals, and the storage part connects the disassembling part 1031 and the installing part 1032. Among them, the disassembling part 1031 is used to disassemble the used replaceable inner lining 300 from the helmet, and the area of the storage part close to the disassembling part 1031 is used to store the used replaceable inner lining 300 removed by the disassembling part 1031. Among them, the area of the storage part close to the installing part 1032 is used to store the unused replaceable inner lining 300, and the installing part 1032 is used to guide and install the replaceable inner lining 300 to the inner side of the helmet.

[0164] The replacement part 103 provided by the present application can store both the used replaceable inner lining 300 and the unused replaceable inner lining 300 through the storage part. The used replaceable inner lining 300 can be disassembled from the helmet through the guiding and assisting functions provided by the disassembly part 1031, and the replaceable inner lining 300 can be guided and installed inside the helmet through the guiding and assisting functions provided by the installation part 1032. The installation, disassembly, and storage of the inner lining 300 can be completed through the replacement part 103.

[0165] Through the replacement part 103 provided by the present application, the user can use the replacement part 103 as a storage tool and an operating tool, or the replacement part 103 can be arranged in a replacement device. The replacement device can be operated by the user on the helmet to dock with the replacement part 103 to complete the replacement of the inner lining 300, or the replacement device is an automated device and can automatically complete the replacement of the helmet inner lining 300.

[0166] In some embodiments, the replacement part 103 is a rod. The two end parts of the replacement part 103 are respectively the disassembly part 1031 and the installation part 1032, and the rod area between the two end parts on the replacement part 103 is the storage part.

[0167] The rod has a length dimension extending along its central axis, and this length dimension provides a space for the replaceable inner linings 300 to be stacked. Multiple used replaceable inner linings 300 can be stacked and sleeved on the area of the replacement part 103 near the disassembly part 1031, and multiple unused replaceable inner linings 300 can be stacked and sleeved on the area of the replacement part 103 near the installation part 1032. Using one rod to complete the positioning and storage of the inner lining 300, and the rod can provide a guiding effect for the disassembly and installation of the inner lining 300.

[0168] In some embodiments, the cross-section of the rod can be circular, oval, or polygonal. In the preferred embodiment of the present application, the rod is a round rod. Exemplarily, the ends of the disassembly part 1031 and the installation part 1032 can both be designed as semi-circular shapes to keep the end faces of the disassembly part 1031 and the installation part 1032 smooth.

[0169] In some embodiments, the replaceable inner lining 300 corresponding to the replacement part 103 can adopt the inner lining 300 provided by the embodiment of the present application with a rigid detachable part 302, and the through-hole 30222 therein is for the disassembly part 1031 and the installation part 1032 to pass through and enter the through-space 2026 of the locking mechanism 202.

[0170] In some embodiments, the storage part includes a first storage part and a second storage part. The first storage part is the rod area near the disassembly part 1031, and the second storage part is the rod area near the installation part 1032. The length of the rod area where the first storage part is located and the length of the rod area where the second storage part is located are configured to increase and decrease reciprocally.

[0171] By configuring the lengths of the rod regions where the first storage portion and the second storage portion are located to be in an inverse relationship, after accommodating a certain number of liners 300 in the storage portion, as the used liners 300 and the unused liners 300 are continuously replaced, the quantities of the two are inversely related. Therefore, the inverse configuration relationship of the rod regions can be used to collect the corresponding inverse quantities of the liners 300.

[0172] The replacement part 103 provided in this embodiment cleverly utilizes the rod length regions of the rod regions to achieve the storage of the used liners 300, and at the same time achieve the storage of the unused liners 300, and enables the storage space to change with the change in the replacement quantity, making full use of the rod regions of the rod member as the storage portion and improving the utilization of the storage space.

[0173] In some embodiments, a proximal force application portion 1031a is provided on at least one side of the disassembly portion 1031 along its radial direction, and the proximal force application portion 1031a protrudes from the rod region of the replacement part 103. The proximal force application portion 1031a has a proximal force application side 1031b facing away from its central axis, and the proximal force application side 1031b is inclined with respect to the central axis. Among them, the proximal force application side 1031b is used to provide a first external force to the helmet when moving towards the helmet along the central axis, and the used replaceable liner 300 is disassembled from the helmet through the first external force.

[0174] Corresponding to the locking mechanism 202 and the replaceable liner 300 provided in the above third embodiment, in some embodiments, proximal force application portions 1031a are respectively provided on both sides of the disassembly portion 1031 along its radial direction, and the two proximal force application portions 1031a are symmetrically arranged with respect to the central axis. The proximal force application side 1031b is adapted to the proximal force receiving side 2024a of the locking mechanism 202, and provides a first external force to the proximal force receiving side 2024a when moving towards the locking mechanism 202 along the second direction, and drives both the first locking member 2021 and the second locking member 2022 to switch from the locking position to the unlocking position through the first external force, so as to disassemble the used replaceable liner 300 from the locking mechanism 202.

[0175] Corresponding to the locking mechanism 202 and the replaceable liner 300 provided in the above first embodiment and second embodiment, a proximal force application portion 1031a is provided on one side of the disassembly portion 1031 along its radial direction, and the proximal force application portion 1031a is inclined with respect to the central axis of the replacement part 103. It drives the second locking member 2022 in the first embodiment or the first locking member 2021 in the second embodiment to switch from the locking position to the unlocking position through a first external force, so as to disassemble the used replaceable liner 300 from the locking mechanism 202.

[0176] Corresponding to the above-described translation setting schemes for the two distal ends 2025, in some embodiments, proximal force application portions 1031a are respectively provided on both sides of the disassembly portion 1031 along its radial direction, and two proximal force application sides 1031b in the two proximal force application portions 1031a are arranged to translate along the radial direction.

[0177] In some embodiments, a pulling-away portion 1031c is provided on at least one side of the disassembly portion 1031 along its radial direction. The pulling-away portion 1031c and the proximal force application portion 1031a are arranged at intervals along the circumferential direction of the disassembling member. The pulling-away portion 1031c is provided with an inclined surface. The pulling-away portion 1031c includes a main body portion a and a telescopic portion b. The main body portion a is connected to the disassembly portion 1031 through the telescopic portion b, so that the pulling-away portion 1031c can telescopically move relative to the disassembly portion 1031 along the radial direction. The pulling-away portion 1031c is used for pulling away and storing the used replaceable inner lining 300 removed from the disassembly portion 1031 to the storage portion in the extended state. In some specific embodiments, pulling-away portions 1031c are respectively provided on both sides of the disassembly portion 1031 along its radial direction, and the two pulling-away portions 1031c are symmetrically arranged with respect to the central axis.

[0178] Based on the design of the extension portion of the above-described replaceable inner lining 300, wherein, the distance from the edge of the second extension portion 30222b to the central axis of the through hole 30222 is less than the maximum distance from the pulling-away portion 1031c to the central axis of the disassembly portion 1031 when the pulling-away portion 1031c is in the extended state, and greater than the maximum distance from the pulling-away portion 1031c to the central axis of the disassembly portion 1031 when the pulling-away portion 1031c is in the contracted state. The natural state of the pulling-away portion 1031c is the extended state. Due to the setting of the inclined surface, the second extension portion 30222b can prevent the extended pulling-away portion 1031c from passing through the through hole 30222 when the replacement member 103 exits the through hole 30222, and can squeeze the pulling-away portion 1031c into the contracted state and allow the pulling-away portion 1031c to pass through the through hole 30222 when the replacement member 103 enters the through hole 30222.

[0179] During the process of the disassembly portion 1031 entering the through hole 30222 and the through space 2026, the pulling-away portion 1031c is squeezed by the second extension portion 30222b and switches from the extended state to the contracted state. After the pulling-away portion 1031c passes through the through hole 30222 and enters the through space 2026, the squeezing force of the second extension portion 30222b on the pulling-away portion 1031c disappears, and the pulling-away portion 1031c naturally switches to the extended state. Synchronously, the two proximal force application 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 inner lining 300 is disassembled. During the process of the disassembly portion 1031 exiting the through space 2026 and the through hole 30222, the pulling-away portion 1031c pulls away the replaceable inner lining 300.

[0180] In some embodiments, an anti - detachment part 1032a is provided on at least one side of the installation part 1032 along its radial direction. The anti - detachment part 1032a includes a main body part a and a telescopic part b. The main body part a is connected to the anti - detachment part 1032a through the telescopic part b, so that the anti - detachment part 1032a can telescopically move relative to the installation part 1032 along the radial direction. The anti - detachment part 1032a is used to prevent the unused replaceable inner lining 300 from detaching from the storage part in the extended state, and is used to allow the unused replaceable inner lining 300 to detach from the installation part 1032 when it is in the contracted state when the unused replaceable inner lining 300 is installed on the helmet. Among them, the telescopic part b is provided with an inclined surface.

[0181] Based on the design of the extension part of the above - mentioned replaceable inner lining 300, among them, 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 anti - detachment part 1032a to the central axis of the installation part 1032 when the anti - detachment part 1032a is in the extended state, and is greater than the maximum distance from the anti - detachment part 1032a to the central axis of the installation part 1032 when the anti - detachment part 1032a is in the contracted state. The natural state of the anti - detachment part 1032a is the extended state, and it prevents the unused replaceable inner lining 300 from detaching from the storage part in the extended state.

After the inner lining 300 is properly assembled, after the anti - detachment part 1032a exits the through - hole space 2026 and the through - hole 30222, the anti - detachment part 1032a pops out and continues to prevent the unused replaceable inner lining 300 from detaching from the storage part.
