Description

Technical Field

[0001] This application belongs to the technical field of wearable devices, and more specifically, it relates to a device for automatically replacing the inner lining of a 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 inner 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 inner linings therein become dirty due to exposure. Users may choose to abandon using shared electric bicycles because of the dirt, or users may choose to use electric bicycles but abandon using helmets, resulting in an increased probability of electric bicycle safety accidents.

[0005] Second, as a shared device, the inner lining of a shared helmet directly contacts the user's head. The hygienic use of the inner 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 hygienic problems of shared electric bicycle helmets and improve the user's willingness and experience of use, there is an urgent need to provide a device that can automatically replace the disposable inner lining of the helmet. Summary of the Invention

[0108] Now, the helmet inner lining automatic replacement device 100 and the shared helmet 200 provided in the embodiments of this application will be described.

[0109] Please refer to Figures 20 to 36 As shown, the helmet inner lining automatic replacement device 100 provided in the embodiments of this application includes a housing 101, a lifting mechanism 102, and a detachable component 104. The housing 101 has a replacement opening 1011. The lifting mechanism 102 is disposed inside the housing 101. The lifting mechanism 102 includes a lifting component 1021 and a driven member 1022, which is disposed along the circumferential direction of the replacement opening 1011. The lifting direction of the driven member 1022 is perpendicular to the circumferential direction of the replacement opening 1011. The driven member 1022 is drivingly connected to the lifting component 1021 and is configured to be able to move closer to or away from the replacement opening 1011 along the lifting direction under the drive of the lifting component 1021. The detachable component 104 is disposed on the side of the driven member 1022 facing the replacement opening 1011. The detachable component 104 is used for detachably mounting the helmet 200. When the helmet 200 is mounted on the detachable component 104, the wearing opening 2011 of the helmet 200 and the replacement opening 1011 are coaxially arranged along the lifting direction.

[0110] In the replacement device 100 provided in this embodiment, the driven member 1022 is drivingly connected to the lifting component 1021 and is configured to be able to move closer to or away from the replacement opening 1011 along the lifting direction under the drive of the lifting component 1021. The detachable component 104 is disposed on the side of the driven member 1022 facing the replacement opening 1011, and it is used for detachably mounting the helmet 200. When the helmet 200 is mounted on the detachable component 104, the wearing opening 2011 of the helmet 200 and the replacement opening 1011 are coaxially arranged along the lifting direction. Thus, through the lifting drive of the helmet 200 by the lifting mechanism 102, the helmet 200 can move reciprocally in the lifting direction. In this way, the helmet 200 can have the inner lining 300 installed and the inner lining 300 removed at the same position through two separate operations before and after, thereby completing the automatic replacement of the inner lining 300.

[0111] In some embodiments, one circumferential end of the driven member 1022 is drivingly connected to the lifting component 1021, and the detachable component 104 is disposed at the other circumferential end of the driven member 1022.

[0112] In this way, the detachable component 104 and the lifting component 1021 are circumferentially offset, which is beneficial to make full use of the circumferential space for arrangement, and can save the space in the lifting direction and reduce the overall volume of the replacement device 100.

[0113] 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 foundation for the detachable installation of the helmet 200, making the support received by the helmet 200 more stable and reliable.

[0114] 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 is inserted into the replacement part 103, it can avoid damaging the lifting component 1021 due to overly rigid contact.

[0115] 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, and 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.

[0116] 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.

[0117] In some embodiments, the lifting component 1021 further includes an optical axis 1021c. The optical axis 1021c is fixed relative to the housing 101, and the optical axis 1021c is parallel and spaced from the transmission lead screw 1021b in the circumferential direction. The driven member 1022 is provided with an optical hole 1022b, and 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.

[0118] 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.

[0119] In some embodiments, the optical axis 1021c and the detachable component 104 are circumferentially arranged on both sides of the transmission lead screw 1021b. That is to say, optionally, the optical axis 1021c is arranged on the side of the transmission lead screw 1021b away from the driven member 1022. In other embodiments, the transmission lead screw 1021b and the detachable component 104 may be circumferentially arranged on both sides of the optical axis 1021c.

[0120] In some embodiments, the replacement device 100 includes two lifting mechanisms 102 and two detachable components 104. The two driven members 1022 in the two lifting mechanisms 102 are arranged opposite to each other in the radial direction of the housing 101, the two detachable components 104 are arranged opposite to each other in the radial direction of the housing 101, and the two detachable components 104 are arranged one by one on the two driven members 1022. Among them, the structures of the two driven members 1022 may be the same or different, and the structures of the two detachable components 104 may be the same or different.

[0121] Through the arrangement of the two detachable components 104 and the two lifting mechanisms 102, it can be ensured that the helmet 200 is lifted and lowered smoothly as a whole, and then inserted into the replacement part 103 with high precision, and the installation of the replaceable lining 300 is successfully completed.

[0122] In some embodiments, the detachable component 104 includes a movable component 1041 and a buffer component 1042. The movable component 1041 is used for detachably installing the helmet 200. The buffer component 1042 extends along the lifting direction. One end of the buffer component 1042 is connected to the movable component 1041, and the other end of the buffer component 1042 is directly or indirectly connected to the driven member 1022. The buffer component 1042 is configured to provide buffering when the helmet 200 is driven by an external force pointing to the replacement port 1011 along the lifting direction and drives the movable component 1041 to move relative to the driven member 1022.

[0123] Among them, the buffer component 1042 can be any elastic component, for example, it can be a linear spring. One end of the buffer component 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 component 1042 is directly or indirectly connected to the driven member 1022. During the process of the locking mechanism 202 of the helmet 200 and the replacement part 103 being inserted into each other, the reaction force of the replacement part 103 on the helmet 200 can be buffered by the buffer component 1042, and the helmet 200 is 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 replacement part 103 are inserted into each other can be prevented from having an adverse effect on the lifting mechanism 102, and this part of the acting force can be absorbed by the buffer component 1042.

[0124] In some embodiments, the detachable component 104 includes two buffer members 1042, and the two buffer members 1042 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.

[0125] In some embodiments, the detachable component 104 further includes a fixing member 1043, and the fixing member 1043 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, and the connecting end 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 the helmet 200 is subjected to an external force pointing to the replacement opening 1011 in the lifting direction and to press the connecting end against the driven member 1022 when the external force is withdrawn.

[0126] 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, and 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.

[0127] In some embodiments, at least two detachable components 104 are provided near the replacement opening 1011, and the two detachable components 104 are arranged at intervals along the circumference of the replacement opening 1011 or arranged in pairs along the radius of the replacement opening 1011. The two detachable components 104 are used for detachably connecting to two detachable structures 2012 on the helmet 200, so that the helmet 200 can be detachably connected to the replacement device 100 to complete the replacement of the inner liner 300.

[0128] Refer to Figures 37 to 42As shown, two detachable components 104 in the replacement device 100 provided by the embodiment of the present application are arranged at intervals along the circumferential direction of the replacement opening 1011 or arranged in pairs along the radial direction of the replacement 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 replacement 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 replacement device 100, the replacement device 100 can complete the replacement of the inner lining 300 of the helmet 200. When the helmet 200 is detached from the replacement device 100, the user can wear the helmet 200 with the replaced inner lining 300 by himself.

[0129] In some embodiments, the two detachable components 104 are arranged in pairs along the radial direction of the replacement opening 1011, and 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.

[0130] By arranging the first detachable component 104a and the second detachable component 104b along the radial direction, the front end side and the rear end side of the helmet 200 can be respectively detachably installed on the replacement device 100, ensuring the stability and balance of the helmet 200 during the lifting process.

[0131] 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 with 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.

[0132] In this embodiment, by virtue 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. 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. Wherein, the first detachable structure 2012a and the second detachable structure 2012b are oppositely arranged along the front-back direction of the helmet 200.

[0133] 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.

[0134] The first elastic member 10413 extends along the radial direction of the replacement device 100, while the second elastic member 10415 is angled with respect to the extension direction of the first elastic member 10413, so as to act on the second elastic member 10415 when the helmet 200 is installed towards the second detachable component 104b and store elastic force therein. Correspondingly, when removing the helmet 200, the second elastic member 10415 can assist the helmet 200 to bounce upward and disengage from the second detachable component 104b through the stored elastic force.

[0135] In some specific embodiments, the second detachable component 104b includes the above-mentioned movable component 1041. The movable component 1041 includes a main body member 10411, a first sliding member 10412, and a first elastic member 10413. The first elastic member 10413 extends along the radial direction.

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.

[0137] Among them, two first elastic members 10413 can be provided. Two setting holes 10412a extending radially are provided on the first sliding member 10412, and 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.

[0138] 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. 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 replacement device 100.

[0139] 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 replacement 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 replacement 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 detachable clamping to the second detachable structure 2012b.

[0140] Thus, during the installation of the helmet 200, the second detachable structure 2012b of the helmet 200 is aligned with the main body part 10411 of the second detachable component 104b, and the helmet 200 is pressed down. The sliding guide surface c provides a guiding effect for the second detachable structure 2012b to be installed towards the second detachable component 104b, so that the convex part e is detachably clamped to the second detachable structure 2012b. Specifically, a slot structure can be provided on the main body part 10411, and the convex part e can be clamped in the slot structure.

[0141] Among them, a position detection device 10416 can be provided on the main body part 10411 for detecting whether the helmet is installed in place.

[0142] Among them, the first elastic member 10413 and the first sliding member 10412 can be arranged in the order of radially inwards or radially outwards. In some embodiments, the first elastic member 10413 is arranged radially outside the first sliding member 10412. One end of the first elastic member 10413 facing inwards is connected to the first sliding member 10412, and the other end of the first elastic member 10413 facing outwards is fixed relative to the main body part 10411.

[0143] 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 replacement opening 1011 towards the inside of the housing 101, the first elastic member 10413 and the second elastic member 10415 are arranged in order, and the first sliding member 10412 and the second sliding member 10414 are arranged in order; 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 part 10411; the second sliding member 10414 is slidably arranged on the main body part 10411, and both the sliding path of the second sliding member 10414 and the extending direction of the second elastic member 10415 are angled with respect to the radial direction.

[0144] Among them, the second elastic member 10415 can be provided as two, and the two second elastic members 10415 are arranged at intervals in the circumferential direction. A configuration hole 10411b is provided on the main body part 10411, and the two first elastic members 10413 are respectively arranged in the two configuration holes 10411b. The upper end of the second elastic member 10415 is fixedly connected to the main body part 10411, and the lower end of the second elastic member 10415 is connected to the second sliding member 10414.

[0145] When the helmet 200 is installed towards the second detachable component 104b, it acts on the two second elastic members 10415 and stores elastic force in them. Correspondingly, when the helmet 200 is removed, the second elastic members 10415 can assist the helmet 200 to bounce upwards and disengage from the second detachable component 104b through the stored elastic force.

[0146] Such as 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 arranged 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 arranged 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 replacement device 100, so that the replacement device 100 can disassemble the replaceable inner lining 300 of the shared helmet 200.

[0147] Since the locking mechanisms 202 are arranged 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, the inner lining 300 of the helmet 200 can be replaced, thereby ensuring the hygiene and safety of the shared helmet 200.

[0148] Furthermore, the detachable structures 2012 are arranged 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 replacement device 100, so that the replacement device 100 can disassemble the replaceable inner lining 300 of the shared helmet 200. When the helmet 200 is detachably connected to the replacement device 100, the replacement device 100 can complete the replacement of the inner lining 300 of the helmet 200. When the helmet 200 is detached from the replacement device 100, the user can wear the helmet 200 with the replaced inner lining 300 by himself.

[0149] 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.

[0150] 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 parts 302 are correspondingly installed on the part of the extension shells 2014. In this way, the rigid locking mechanisms 202 and the detachable parts 302 will not have an adverse impact on the wearing comfort of the user.

[0151] 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.

[0152] 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, and 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 replacement 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.

[0153] 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, it can make the following second detachable structure 2012b 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.

[0154] 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.

[0155] 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 installation and / or disassembly of the inner lining 300.

[0156] 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 installation and / or disassembly position of the inner lining 300 from being at the same height, making it difficult to set up the lifting mechanism 102.

[0157] 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 a first direction, and both the first slideway 2031 and the second slideway 2032 extend along the first direction; the following 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.

[0158] 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 in a 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 respectively slidably connected to the first proximal slideway 2031a and the first distal slideway 2031a.

[0159] 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 in a 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 respectively slidably connected to the second proximal slideway 2032a and the second distal slideway 2032a.

[0160] 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 sliding track 2031 and the second sliding guide 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.

[0161] As Figures 1 to 17 , such as Figure 29 and Figure 30 As shown in

[0162] Among them, the replacement part 103 has a disassembly part 1031. When the helmet 200 is installed on the replacement device 100, the disassembly part 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 replacement part 103 to move up and down relative to the other, and insert the replacement part 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.

[0163] The lifting mechanism 102 can drive one of the helmet 200 and the replacement part 103 to move up and down relative to the other, and insert the replacement part 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 providing the lifting mechanism 102 in the replacement device 100, the lifting mechanism 102 selectively drives the helmet 200 or the replacement part 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.

[0164] In some embodiments, a plurality of locking mechanisms 202 are sequentially arranged along the circumferential direction of the helmet shell 201. The plurality of locking mechanisms 202 are used to lock or unlock the same replaceable inner lining 300. The replacement device 100 includes a plurality of replacement parts 103. The plurality of disassembly parts 1031 of the plurality of replacement parts 103 are arranged in one-to-one correspondence with the plurality of locking mechanisms 202.

[0165] In some 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 periphery 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. 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.

[0166] 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, a plurality of detachable connecting portions 3022 of the plurality of detachable members 302 are arranged in one-to-one correspondence with the plurality of locking mechanisms 202, and a plurality of disassembly portions 1031 of the plurality of replacement members 103 can detach the plurality of detachable members 302 from the plurality of locking mechanisms 202 one by one. After the plurality of detachable members 302 are detached, the inner lining 300 where the plurality of detachable members 302 are located is detached.

[0167] In some embodiments, the locking mechanism 202 includes two locking members. The locking members have a proximal end 2024 and a distal end 2025 that are opposite to each other in a first direction. The proximal end 2024 of any one of the locking members 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 replaceable inner lining 300. Any one of the locking members can move relative to the other locking member in the first direction. 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.

[0168] When the lifting mechanism 102 drives one of the helmet 200 and the replacement 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 locking position to the unlocking position; wherein, the first direction is perpendicular to the lifting direction.

[0169] 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 disassembly 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.

[0170] During the process in which 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.

[0171] In some embodiments, a pair of proximal force-receiving sides 2024a facing each other are provided on the two proximal ends 2024. The proximal force-receiving sides 2024a are inclined with respect to the first direction, and the pair of proximal force-receiving sides 2024a are symmetrically arranged along the first direction. Proximal force-applying portions 1031a are respectively provided on both sides of the disassembly portion 1031 along the first direction. The two proximal force-applying portions 1031a are symmetrically arranged along the first direction, and the two proximal force-applying portions 1031a are used to abut against the pair of proximal force-receiving sides 2024a.

[0172] When the lifting mechanism 102 drives one of the helmet 200 and the replacement 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 along the first direction. By the pair of proximal force-receiving sides 2024a of the pair of proximal force-applying portions 1031a acting on the pair of proximal force-receiving sides 2024a of the two proximal ends 2024, the two proximal ends 2024 are forced to move away from each other, so that 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.

[0173] 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 described above. The hole edge of the through hole 30222 includes two first expansion parts 30222a and two second expansion parts 30222b that are oppositely arranged. The distance from the first expansion part 30222a to the hole axis of the through hole 30222 is greater than the distance from the second expansion part 30222b to the hole axis. The first expansion parts 30222a and the second expansion 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 through the disassembly part 1031 of the replacement part 103.

[0174] Among them, the maximum distance between the two first expansion parts 30222a in the first direction is greater than the maximum distance between the two proximal end force application parts 1031a in the first direction, so as to allow the two proximal end force application parts 1031a to smoothly pass through the space between the two first expansion parts 30222a, contact the two proximal end force receiving sides 2024a of the two proximal ends 2024 on the two locking parts and apply the second external force described above, and allow the two proximal end force application parts 1031a to smoothly exit the through hole 30222 and the through space 2026.

[0175] 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 force application 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.

[0176] Furthermore, the distance from the edge of the second expansion 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 expansion part 30222b is the extended state. Due to the setting of the inclined surface, the second expansion part 30222b can prevent the extended pulling part 1031c from passing through the through hole 30222 when the replacement part 103 exits the through hole 30222, and can 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 103 enters the through hole 30222.

[0177] Specifically, during the process of the disassembly part 1031 entering the through hole 30222 and the through space 2026, the carrying part 1031c is squeezed by the second expanding part 30222b and switches from the extended state to the contracted state. After the carrying part 1031c passes through the through hole 30222 and enters the through space 2026, the squeezing force of the second expanding part 30222b on the carrying part 1031c disappears, and the carrying part 1031c naturally switches to the extended state. Synchronously, the two proximal applying parts 1031a apply a second external force to the two proximal ends 2024 and drive the two distal ends 2025 of the first locking part 2021 and the second locking part 2022 to approach each other, and the replaceable inner lining 300 is disassembled. During the process of the disassembly part 1031 exiting the through space 2026 and the through hole 30222, the carrying part 1031c carries away the replaceable inner lining 300.

[0178] As Figures 1 to 17 , and as Figure 27 and Figure 28 shown, in the second application embodiment, the replacement device 100 provided by the embodiment of the present application can install the inner lining 300 separately.

[0179] 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 switch between the two. The locking mechanism 202 can overcome the elastic force of the elastic member 2023 under the action of an external force and be in the unlocking position, and be in the locking position under the elastic force of the elastic member 2023.

[0180] The replacement device 100 includes a replacement part 103. The replacement part 103 has an interconnected installation part 1032 and a storage part. The replaceable inner 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 replacement 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 replacement part 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, so that the locking mechanism 202 switches from the locking position to the unlocking position, and locks the detachable part 302 under the elastic force of the elastic member 2023.

[0181] The lifting mechanism 102 can drive one of the helmet 200 and the replacement part 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 part 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 part 2023, and then completing the automatic installation of the replaceable inner lining 300. By arranging the lifting mechanism 102 in the replacement device 100, the lifting mechanism 102 is alternatively used to drive the helmet 200 or the replacement part 103, and the disposable inner lining 300 is conveniently installed on the helmet 200.

[0182] In some embodiments, a plurality of locking mechanisms 202 are sequentially arranged along the circumferential direction of the helmet shell 201. The replaceable inner 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 inner lining 300. The plurality of locking mechanisms 202 and the plurality of detachable parts 302 of the same replaceable inner lining 300 are arranged in a one-to-one correspondence. The replacement device 100 includes a plurality of replacement parts 103, and the plurality of detachable parts 302 of the same replaceable inner lining 300 are sleeved on the plurality of replacement parts 103 in a one-to-one manner.

[0183] In some embodiments, the replaceable inner lining 300 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 periphery 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.

[0184] When a plurality of 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 extrusion docking with the plurality of locking mechanisms 202, and the plurality of installation parts 1032 of the plurality of replacement 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 installed on the locking mechanism 202.

[0185] In some embodiments, the locking mechanism 202 includes two locking parts, the locking parts have 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 of the locking parts 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.

[0186] The two locking members are respectively a first locking member 2021 and a second locking member 2022. 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. 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.

[0187] The lifting mechanism 102 drives one of the helmet 200 and the replacement part 103 to lift relative to the other. The mounting portion 1032 enters between the two proximal ends 2024, and the inner lining 300 and the locking mechanism 202 are squeezed and butted in the lifting direction, 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, 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 unlocked position to the unlocked position. The inner lining 300 is mounted on the locking mechanism 202 and is locked under the action of the elastic force of the elastic member 2023.

[0188] Since there are two elastic members 2023 in this embodiment, during the process of the second locking member 2022 switching from the locked position to the unlocked position in the first direction and the first locking member 2021 switching from the locked position to the unlocked 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 unlocked position to the locked position and the first locking member 2021 synchronously switches from the unlocked position to the locked position.

[0189] In some embodiments, two distal ends 2025 are provided with a pair of force-receiving sides of the distal ends 2025 facing away from each other. The force-receiving sides of the distal ends 2025 are inclined relative to the first direction, and the pair of force-receiving sides of the distal ends 2025 are symmetrically arranged along the first direction. Two distal-end force-applying parts 30221 are provided with a pair of distal-end force-applying sides 30221a facing each other. The distal-end force-applying sides 30221a are inclined relative to the first direction, and the pair of distal-end force-applying sides 30221a are symmetrically arranged along the first direction. The pair of distal-end force-applying sides 30221a are used to apply force to the pair of force-receiving sides of the two distal ends 2025 and overcome the elastic force of the elastic member 2023.

[0190] During the automatic installation of the replaceable lining 300 onto the locking mechanism 202, a plurality of detachable parts 302 are aligned one by one with a plurality of locking mechanisms 202. A pair of distal-end force-applying parts 30221 of the detachable connecting part 3022 in the detachable part 302 apply force to the pair of force-receiving sides of the two distal ends 2025 in the two distal ends 2025 through a pair of distal-end force-applying sides 30221a. Since both the distal-end force-applying sides 30221a and the force-receiving sides of the distal ends 2025 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.

[0191] Furthermore, two distal-end force-applying parts 30221 are provided with a pair of second clamping structures 2025b facing each other. The force-receiving sides of the distal ends 2025 and the second clamping structures 2025b on the same distal-end force-applying part are arranged in sequence along the lifting direction and are smoothly connected. The two second clamping structures 2025b are clamped to a pair of second clamping structures 2025b under the elastic force of the elastic member 2023.

[0192] Since the distal-end force-applying sides 30221a are smoothly connected to the first clamping structures 30221b, and the force-receiving sides of the distal ends 2025 and the second clamping structures 2025b are smoothly connected, as the movement continues, the pair of force-receiving sides of the distal ends 2025 are separated from the pair of distal-end force-applying sides 30221a. Under the elastic force of the two elastic members 2023, the two locking parts move away from each other respectively, and then the first clamping structures 30221b and the second clamping structures 2025b are smoothly clamped.

[0193] Among them, one of the first clamping structure 30221b and the second clamping structure 2025b can be a groove structure, and the other can be a protrusion structure. As an example, in some specific embodiments, the first clamping structure 30221b can be a groove structure, specifically a notch structure penetrating the thickness of the detachable part 302. The second clamping structure 2025b can be a protrusion structure, and its contour can just be clamped into the notch structure.

[0194] 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 described above. The hole edge of the through hole 30222 includes two first extension parts 30222a and two second extension parts 30222b which 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, the two distal end force application parts 30221 are provided outside the two first extension parts 30222a. Among them, both the first extension part 30222a and the second extension part 30222b are semicircular. Among them, both the through hole 30222 and the through space 2026 are used for passing through the installation part 1032 of the replacement part 103.

[0195] 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 during the installation of the unused replaceable inner lining 300 onto the helmet 200. Among them, the telescopic part b is provided with an inclined surface.

[0196] Based on the design of the extension part of the replaceable inner lining 300 described above, 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. Due to the setting of the inclined surface, the second extension part 30222b can squeeze the anti - detachment part 1032a into the contracted state when the replacement part 103 enters the through hole 30222 and allow the anti - detachment part 1032a to pass through the through hole 30222.

[0197] Based on the above design of the cage 203, the cage 203 is provided with an inclined surface corresponding to the inclined surface of the anti - detachment part 1032a. After the anti - detachment part 1032a enters the through - hole 30222, the inclined surface of the anti - detachment part 1032a just contacts the inclined surface on the cage 203 and continues to maintain the contracted state. After the inner lining 300 is properly assembled, when the anti - detachment part 1032a exits the through - space 2026 and the through - hole 30222, the anti - detachment part 1032a pops up and continues to prevent the unused replaceable inner lining 300 from detaching from the storage part.

[0198] As Figures 31 to 36 shown in the third application embodiment, the above - mentioned first application embodiment and second application embodiment can be used in combination. For example, the disassembly part 1031 and the installation part 1032 can be arranged at two ends of the same replacement part 103, or switched by flipping. Or, the replacement device 100 provided by the first application embodiment and the replacement device 100 provided by the second application embodiment are arranged in sequence along the horizontal direction, so that the user can disassemble the inner lining 300 and can install the inner lining 300.

[0199] 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 principle of the present application shall be included within the protection scope of the present application.
