[0112] The helmet lining automatic replacement device 100 and the shared helmet 200 provided in the embodiments of the present application are now described.

[0113] See also Figures 20 to 36As shown, the automatic helmet liner replacement device 100 provided in an embodiment of the present application includes a housing 101, a lifting mechanism 102, and a detachable assembly 104. The housing 101 has a replacement opening 1011. The lifting mechanism 102 is disposed within the housing 101. The lifting mechanism 102 includes a lifting assembly 1021 and a driven member 1022. The driven member 1022 is driven to extend along the circumference of the replacement opening 1011, and the lifting direction of the driven member 1022 is perpendicular to the circumference of the replacement opening 1011. The driven member 1022 is transmission-connected to the lifting assembly 1021 and is configured to move closer to or further from the replacement opening 1011 in a lifting direction under the drive of the lifting assembly 1021. The detachable assembly 104 is disposed on the side of the driven member 1022 facing the replacement opening 1011. The detachable assembly 104 is used to detachably mount a helmet 200. When the helmet 200 is mounted on the detachable assembly 104, the wearing opening 2011 of the helmet 200 and the replacement opening 1011 are coaxially arranged along the lifting direction.

[0114] In the replacement device 100 provided in this embodiment, a driven member 1022 is connected to a lifting assembly 1021 and is configured to be able to move closer to or away from a replacement port 1011 along a lifting direction under the drive of the lifting assembly 1021. A detachable assembly 104 is provided on the driven member 1022 on a side facing the replacement port 1011, and is used to detachably install a helmet 200. When the helmet 200 is installed on the detachable assembly 104, the wearing port 2011 and the replacement port 1011 of the helmet 200 are coaxially arranged along the lifting direction. In this way, the lifting mechanism 102 drives the helmet 200 to move back and forth in the lifting direction, so that the helmet 200 can complete the installation and removal of the lining 300 twice in the same position, thereby completing the automatic replacement of the lining 300.

[0115] In some embodiments, one end of the driven component 1022 along the circumferential direction is transmission-connected to the lifting assembly 1021 , and the detachable assembly 104 is disposed on the other end of the driven component 1022 along the circumferential direction.

[0116] In this way, the detachable component 104 and the lifting component 1021 are staggered along the circumferential direction, which is conducive to making full use of the space along the circumferential direction for arrangement, and can save space in the lifting direction and reduce the overall volume of the replacement device 100.

[0117] In some embodiments, the driven member 1022 is a cantilever beam, and the other end of the driven member 1022 is suspended. The cantilever beam can provide a good support base for the detachable installation of the helmet 200, making the support of the helmet 200 more stable and reliable.

[0118] In addition, the lifting assembly 1021 is only provided on one side of the driving member 1021a along the circumferential direction, and the other side is suspended, so that the driven member 1022 can have a slight floating along the lifting direction. When the locking mechanism 202 and the replacement member 103 on the helmet 200 are plugged in, the lifting assembly 1021 can be avoided from being damaged by overly rigid contact.

[0119] In some embodiments, the lifting assembly 1021 includes a driving member 1021a and a transmission screw 1021b, which are coaxially arranged along the lifting direction. The driven member 1022 is provided with a transmission hole 1022a, which passes through the driven member 1022 along the lifting direction. The transmission screw 1021b is driven and inserted into the transmission hole 1022a and is configured to drive the driven member 1022 in the lifting direction through the transmission hole 1022a under the drive of the driving member 1021a.

[0120] By setting the transmission screw 1021b and providing the driven part 1022 with a transmission hole 1022a, the transmission screw 1021b is inserted into the transmission hole 1022a. The transmission screw 1021b can not only provide a guiding function for the driven part 1022 to rise and fall, but also enable the driven part 1022 to rise and fall stably, thereby improving the lifting and lowering stability of the detachable component 104 and the helmet 200.

[0121] In some embodiments, the lifting assembly 1021 also includes an optical axis 1021c, which is fixed relative to the housing 101, and the optical axis 1021c and the transmission screw 1021b are parallel to and spaced apart in the circumferential direction; the driven part 1022 is provided with a light hole 1022b, which passes through the driven part 1022 along the lifting direction, and the light hole 1022b is sleeved on the optical axis 1021c and can move along the optical axis 1021c.

[0122] By setting the optical axis 1021c and providing the driven part 1022 with a light hole 1022b, the optical axis 1021c is driven and plugged into the light hole 1022b. The optical axis 1021c can not only provide a guide for the driven part 1022 to rise and fall, but also enable the driven part 1022 to rise and fall stably, thereby further improving the lifting and lowering stability of the detachable component 104 and the helmet 200.

[0123] In some embodiments, the optical axis 1021c and the detachable assembly 104 are circumferentially disposed on either side of the transmission screw 1021b. In other words, the optical axis 1021c is optionally disposed on the side of the transmission screw 1021b facing away from the driven component 1022. In other embodiments, the transmission screw 1021b and the detachable assembly 104 may be circumferentially disposed on either side of the optical axis 1021c.

[0124] In some embodiments, the replacement device 100 includes two lifting mechanisms 102 and two detachable components 104. The two driven parts 1022 of the two lifting mechanisms 102 are arranged radially opposite to each other along the housing 101, and the two detachable components 104 are arranged radially opposite to each other along the housing 101. The two detachable components 104 are arranged one-to-one on the two driven parts 1022. The two driven parts 1022 may have the same or different structures, and the two detachable components 104 may have the same or different structures.

[0125] By setting up two detachable components 104 and two lifting mechanisms 102, it can be ensured that the helmet 200 can be raised and lowered smoothly as a whole, and then plugged into the replacement part 103 with high precision, and the installation of the replaceable liner 300 can be successfully completed.

[0126] In some embodiments, the detachable assembly 104 includes a movable assembly 1041 and a buffer 1042. The movable assembly 1041 is used to detachably mount the helmet 200. The buffer 1042 extends along the lifting direction. One end of the buffer 1042 is connected to the movable assembly 1041, and the other end of the buffer 1042 is directly or indirectly connected to the driven component 1022. The buffer 1042 is configured to provide a buffer when the helmet 200 is subjected to an external force directed toward the replacement port 1011 in the lifting direction, which drives the movable assembly 1041 to move relative to the driven component 1022.

[0127] The buffer 1042 can be any elastic component, such as a linear spring. One end of the buffer 1042 is connected to the movable component 1041, and the movable component 1041 can be detachably mounted on the helmet 200. The other end of the buffer 1042 is directly or indirectly connected to the driven component 1022. During the process of plugging the locking mechanism 202 of the helmet 200 and the replacement component 103 into each other, the reaction force of the replacement component 103 on the helmet 200 can be buffered by the buffer 1042, allowing the helmet 200 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 component 103 are plugged into each other can be avoided. The reaction force can be absorbed by the buffer 1042.

[0128] In some embodiments, the detachable assembly 104 includes two buffer members 1042, which are circumferentially disposed on both sides of the movable assembly 1041. The two buffer members 1042 arranged circumferentially can provide a more effective and balanced buffering effect.

[0129] In some embodiments, the detachable component 104 further includes a fixing member 1043, which has a fixing end 1043a and a limiting end 1043b. The fixing end 1043a is fixedly connected to the driven part 1022, and the limiting end 1043b and the driven part 1022 are spaced apart along the lifting direction. The movable component 1041 has a connecting end, which is located between the limiting end 1043b and the driven part 1022 along 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 directed toward the replacement port 1011 along the lifting direction, and to press the connecting end against the driven part 1022 when the external force is removed.

[0130] The fixed end 1043a of the fixing member 1043 is connected to the driven member 1022. After the helmet 200 is lowered into position, the fixing member 1043 is fixed relative to the driven member 1022, that is, relative to the position of the lifting assembly 1021. The connecting end of the movable assembly 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. In this way, when the helmet 200 is slightly moved backward by the reaction force, the movable assembly 1041 is driven by the helmet 200 to move slightly backward synchronously, that is, move toward the limiting end 1043b, and the buffer member 1042 is compressed to absorb the reaction force.

[0131] In some embodiments, at least two detachable components 104 are provided near the replacement port 1011. The two detachable components 104 are arranged at circumferential intervals along the replacement port 1011 or are arranged in pairs along the radial direction of the replacement port 1011. The two detachable components 104 are used to be detachably connected to the 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 liner 300.

[0132] Reference Figures 37 to 42 As shown, the two detachable components 104 in the replacement device 100 provided in the embodiment of the present application are arranged at intervals along the circumference of the replacement port 1011 or arranged in pairs along the radial direction of the replacement port 1011. The two detachable components 104 are used to detachably connect with the 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 liner 300. Through the detachable components 104, the user can detach and assemble the helmet 200. When the helmet 200 is detachably connected to the replacement device 100, the replacement device 100 can complete the replacement of the liner 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 liner 300.

[0133] In some embodiments, two detachable components 104 are arranged in pairs along the radial direction of the replacement port 1011, namely 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 to be detachably connected to the first detachable structure 2012a on the front side of the helmet 200, and the second detachable component 104b is used to be detachably connected to the second detachable structure 2012b on the rear side of the helmet 200.

[0134] By means of the first detachable component 104a and the second detachable component 104b arranged radially, the front end side and the rear end side of the helmet 200 can be detachably mounted on the replacement device 100 respectively, thereby ensuring the stability and balance of the helmet 200 during the lifting process.

[0135] In some embodiments, the second detachable component 104b includes a first elastic member 10413 extending radially, and the first detachable component 104a includes a bayonet structure or a protrusion structure extending radially; the first elastic member 10413 is configured so 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 abutment 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.

[0136] In this embodiment, the second detachable structure 2012b described below can overcome the first elastic force of the first elastic member 10413 and engage with the second detachable component 104b by virtue of its rigid contact force with the first detachable component 104a. The second detachable structure 2012b remains engaged with the second detachable component 104b under the elastic force of the first elastic member 10413. This facilitates a labor-saving operation when the user detaches the helmet 200, allowing the user to conveniently install the helmet 200 between the first detachable component 104a and the second detachable component 104b. The first detachable structure 2012a and the second detachable structure 2012b are disposed opposite each other along the front-to-back direction of the helmet 200.

[0137] In some embodiments, the second detachable component 104b further includes a second elastic member 10415, and the second elastic member 10415 and the first elastic member 10413 are arranged in radial order, and the two are arranged at an angle; the second elastic member 10415 is configured to synchronously act on the second elastic member 10415 and store elastic force when the second detachable structure 2012b is engaged toward 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.

[0138] The first elastic member 10413 extends radially along the replacement device 100, while the second elastic member 10415 is angled relative to the extension direction of the first elastic member 10413. This allows the second elastic member 10415 to store elastic force when the helmet 200 is installed toward the second detachable assembly 104b. Accordingly, when the helmet 200 is removed, the stored elastic force in the second elastic member 10415 helps the helmet 200 bounce upward and disengage from the second detachable assembly 104b.

[0139] In some specific embodiments, the second detachable component 104b includes the aforementioned movable component 1041, which includes a main body 10411, a first sliding member 10412, and a first elastic member 10413. The first elastic member 10413 extends radially, with one end connected to the first sliding member 10412 and the other end fixed relative to the main body 10411. The first sliding member 10412 is slidably disposed on the main body 10411 and is capable of sliding radially. The first sliding member 10412 is configured to detachably engage with the second detachable structure 2012b of the helmet 200.

[0140] The detachable assembly 104 includes the two aforementioned fixing members 1043, and the main body 10411 includes the two aforementioned connecting ends, which are respectively disposed on either side of the main body 10411 along the circumferential direction. The two fixing members 1043 are also respectively disposed on either side of the main body 10411 along the circumferential direction, and the two buffer members 1042 are respectively disposed between the two limiting ends 1043b and the two connecting ends. In this way, the movable portion can be balanced and elastically supported between the two fixing members 1043 by the two buffer members 1042 through the main body 10411, that is, the movable portion is balanced and elastically supported on the driven member 1022.

[0141] Among them, the first elastic member 10413 can be set to two, and the first sliding member 10412 is provided with two setting holes 10412a extending radially. The two first elastic members 10413 are respectively arranged in the two setting holes 10412a, and the side of the first elastic member 10413 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 10411.

[0142] The first detachable structure 2012a of the helmet 200 is located on the outer wall of the front end of the helmet shell 201, and the second detachable structure 2012b is located on the outer wall of the rear end of the helmet shell 201. The second detachable structure 2012b includes a sliding guide surface c and a snap-in groove d, which are arranged in sequence and smoothly connected along the direction from the wearing opening 2011 to the vertex f. The sliding guide surface c gradually moves away from the central axis along the direction from the wearing opening 2011 to the vertex f, while the snap-in groove d is recessed toward the interior of the helmet shell 201 along the meridian of the helmet shell 201. The sliding guide surface c is used to provide guidance when the second detachable structure 2012b is installed on the replacement device 100.

[0143] Correspondingly, a sliding guide surface c and a protrusion e are provided on the side of the first sliding member 10412 facing away from the first elastic member 10413. The sliding guide surface c and the protrusion e are arranged in sequence and smoothly connected along the direction of the replacement port 1011 pointing to the inside of the shell 101; the sliding guide surface c gradually approaches the central axis of the shell 101 along the direction of the replacement port 1011 pointing to the inside of the shell 101, and the protrusion e is arranged to protrude toward the central axis along the longitudinal direction of the shell 101; wherein, the sliding guide surface c is used to provide guidance when the second detachable structure 2012b is installed to the second detachable component 104b, and the protrusion e is used to be detachably connected to the second detachable structure 2012b.

[0144] In this way, during the installation of the helmet 200, the second detachable structure 2012b of the helmet 200 is aligned with the main body 10411 of the second detachable component 104b and the helmet 200 is pressed down. The sliding guide surface c is used to provide a guiding function for the second detachable structure 2012b to be installed toward the second detachable component 104b, so that the protrusion e can be detachably connected to the second detachable structure 2012b. Specifically, a slot structure can be set on the main body 10411, and the protrusion e can be connected to the slot structure.

[0145] Among them, a position detection device 10416 can be set on the main body 10411 to detect whether the helmet is installed in place.

[0146] The first elastic member 10413 and the first sliding member 10412 can be arranged in a radially inward or radially outward direction. In some embodiments, the first elastic member 10413 is radially arranged outside the first sliding member 10412, with one end of the first elastic member 10413 facing inward connected to the first sliding member 10412, and the other end of the first elastic member 10413 facing outward fixed relative to the main member 10411.

[0147] 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 port 1011 toward the interior of the housing 101, the first elastic member 10413 and the second elastic member 10415 are sequentially arranged, and the first sliding member 10412 and the second sliding member 10414 are sequentially arranged. One end of the second elastic member 10415 is connected to the second sliding member 10414, and the other end is fixed relative to the main body 10411. The second sliding member 10414 is slidably disposed on the main body 10411, and the sliding path of the second sliding member 10414 and the extension direction of the second elastic member 10415 are both angled with respect to the radial direction.

[0148] Among them, the second elastic member 10415 can be set to two, the two second elastic members 10415 are arranged at intervals along the circumferential direction, the main body 10411 is provided with a configuration hole 10411b, 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 10411, and the lower end of the second elastic member 10415 is connected to the second sliding member 10414.

[0149] When the helmet 200 is mounted toward the second detachable assembly 104b, the two second elastic members 10415 act on the two second elastic members 10415 and store elastic force therein. Correspondingly, when the helmet 200 is removed, the second elastic members 10415 can assist the helmet 200 in bouncing upward and disengaging from the second detachable assembly 104b through the stored elastic force.

[0150] like Figures 18 to 20 As shown, the shared helmet 200 provided in 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 mechanism 202 is provided on the inner wall of the helmet shell 201, and the two locking mechanisms 202 are arranged in pairs along the warp direction of the helmet shell 201 or are arranged at intervals along the circumferential direction of the helmet shell 201. The locking mechanism 202 is used to detachably connect the replaceable liner 300. The detachable structure 2012 is provided on the outer wall of the helmet shell 201, and the two detachable structures 2012 are arranged in pairs along the warp direction of the helmet shell 201 or are arranged at intervals along the circumferential direction of the helmet shell 201. The detachable structure 2012 is used to detachably connect the replacement device 100, so that the replacement device 100 can remove the replaceable liner 300 from the shared helmet 200.

[0151] Since the locking mechanism 202 is 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 arranged at intervals along the circumferential direction of the helmet shell 201. The locking mechanism 202 is used to detachably connect the replaceable lining 300, so that the lining 300 of the helmet 200 can be replaced, thereby ensuring the hygiene and safety of the shared helmet 200.

[0152] Furthermore, a detachable structure 2012 is provided on the outer wall of the helmet shell 201. Two detachable structures 2012 are arranged in pairs along the longitudinal direction of the helmet shell 201 or spaced apart along the circumference of the helmet shell 201. The detachable structures 2012 are used to detachably connect to the replacement device 100, allowing the replacement device 100 to remove the replaceable liner 300 from 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 liner 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 liner 300.

[0153] In some embodiments, the helmet shell 201 includes a main shell 2013 and at least two extension shells 2014. The extension shells 2014 are integrally connected to the periphery of the main shell 2013 and protrude from the main shell 2013 along the longitudinal direction of the main shell 2013. The at least two locking mechanisms 202 are detachably mounted in a one-to-one relationship in the at least two mounting shells.

[0154] By distinguishing the main shell 2013 from the extension shell 2014, the portion intended for wear by the user and the portion intended for detachable installation of the liner 300 can be distinguished, so that the liner 300 body fits within the inner wall of the main shell 2013, while the detachable member 302 corresponds to the portion installed within the extension shell 2014. In this way, the rigid locking mechanism 202 and the detachable member 302 do not adversely affect the user's wearing comfort.

[0155] 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. The first detachable structure 2012a and the second detachable structure 2012b are both integrally formed on the helmet shell 201, and the first detachable structure 2012a and the second detachable structure 2012b have different structures. Specifically, the first detachable structure 2012a is located on the outer wall of the front end of the helmet shell 201, and the second detachable structure 2012b is located on the outer wall of the rear end of the helmet shell 201.

[0156] In some specific embodiments, the helmet shell 201 has a wearing opening 2011 and a vertex f that are arranged relative to each other along its central axis; the second detachable structure 2012b includes a sliding guide surface c and a snap-in groove d, which are arranged in sequence and smoothly connected along the direction from the wearing opening 2011 to the vertex f. 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 snap-in groove d is recessed toward the interior of the helmet shell 201 along the longitudinal direction of the helmet shell 201. 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 snap-in structure or a protruding structure, and the first detachable structure 2012a extends along the longitudinal direction of the helmet shell 201.

[0157] Correspondingly, the structures of the first detachable component 104a and the second detachable component 104b are configured differently so that when the helmet 200 is attached to the first detachable component 104a via the first detachable structure 2012a described below, the second detachable structure 2012b can overcome the first elastic force of the first elastic component 10413 and attach to the second detachable component 104b by virtue of the rigid abutment with the first detachable component 104a. The second detachable structure 2012b remains attached to the second detachable component 104b under the elastic force of the first elastic component 10413. This facilitates a labor-saving operation when the user detaches the helmet 200, allowing the user to conveniently install the helmet 200 between the first detachable component 104a and the second detachable component 104b. The first detachable structure 2012a and the second detachable structure 2012b are disposed relative to each other along the front-to-back direction of the helmet 200.

[0158] In some embodiments, the helmet shell 201 has a first peripheral edge 2015 and a second peripheral edge 2016, with the first peripheral edge 2015 and the second peripheral edge 2016 being located on either side of a line connecting the front end and the rear end. The helmet 200 includes two pairs of locking mechanisms 202. In any pair of locking mechanisms 202, one locking mechanism 202 is located on the first peripheral edge 2015, and the other locking mechanism 202 is located on the second peripheral edge 2016.

[0159] As mentioned 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 arranged on both sides of the line connecting the front end side and the rear end side of the helmet 200, that is, the locking mechanism 202 and the first detachable structure 2012a and the second detachable structure 2012b are spaced apart along the circumferential direction to prevent interference between the detachable installation of the helmet 200 and the installation and / or removal of the lining 300.

[0160] In some embodiments, the helmet shell 201 has a central axis passing through the vertex f of the helmet shell 201. Along the central axis, the locking mechanism 202, the detachable structure 2012, and the vertex f are sequentially spaced apart. In other words, the locking mechanism 202, the first detachable structure 2012a, and the second detachable structure 2012b are spaced apart axially along the helmet 200. This prevents the detachable installation position of the helmet 200 and the installation and / or removal position of the liner 300 from being at the same height, making it difficult to install the lifting mechanism 102.

[0161] In some embodiments, the locking mechanism 202 also includes a retaining frame 203, which is connected to the inner wall of the helmet shell 201, and a first slide 2031 and a second slide 2032 are provided on the side of the retaining frame 203 facing away from the inner wall of the helmet shell 201; the first slide 2031 and the second slide 2032 are arranged in sequence along the first direction, and the first slide 2031 and the second slide 2032 both extend along the first direction; the following two locking members are respectively the first locking member 2021 and the second locking member 2022, the first locking member 2021 is slidably connected to the first slide 2031, and the second locking member 2022 is slidably connected to the second slide 2032.

[0162] In a specific embodiment, the first slide 2031 may include a first proximal slide 2031a and a first distal slide 2031b, wherein the first proximal slide 2031a and the first distal slide 2031a are sequentially arranged along a first direction, and both the first proximal slide 2031a and the first distal slide 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 slide 2031a and the first distal slide 2031a, respectively.

[0163] In a specific embodiment, the second slide 2032 may include a second proximal slide 2032a and a second distal slide 2032b, the second proximal slide 2032a and the second distal slide 2032b being sequentially arranged along the first direction, and both the second proximal slide 2032a and the second distal slide 2032b extending 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 slide 2032a and the second distal slide 2032a, respectively.

[0164] As a preferred embodiment of the locking mechanism 202 of the present application, the locking mechanism 202 may further include a locking shell 204, which may be fixedly connected to the inner wall of the helmet shell 201 of the helmet 200, and the upper end of the retaining frame 203 is connected to the locking shell 204, and the above-mentioned first slide 2031 and second slide guide are arranged on the lower end of the retaining frame 203, and the first locking member 2021 and the second locking member 2022 are respectively slidably connected to the lower end of the retaining frame 203, that is, in the direction of the wearing opening 2011.

[0165] like Figures 1 to 17 ,like Figure 29 and Figure 30 As shown, in the first application embodiment, the replacement device 100 provided in the embodiment of the present application can disassemble the liner 300 separately.

[0166] 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 relatively 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 rise and fall relative to the other, and make the replacement part 103 inserted 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.

[0167] The lifting mechanism 102 can drive either the helmet 200 or the replacement part 103 to rise or fall relative to the other, inserting the replacement part 103 into the locking mechanism 202 in the lifting direction and driving the locking mechanism 202 to switch from a locked position to an unlocked position. By providing the lifting mechanism 102 in the replacement device 100, the lifting mechanism 102 selectively drives either the helmet 200 or the replacement part 103, conveniently removing the disposable liner 300 from the helmet 200, allowing the user to subsequently manually or automatically replace the disposable liner 300.

[0168] In some embodiments, multiple locking mechanisms 202 are sequentially arranged along the circumference of the helmet shell 201, and the multiple locking mechanisms 202 are used to lock or unlock the same replaceable liner 300. The replacement device 100 includes multiple replacement parts 103, and the multiple detachable portions 1031 of the multiple replacement parts 103 are used to be arranged one-to-one with the multiple locking mechanisms 202.

[0169] In some embodiments, the replaceable liner 300 includes a liner body 300 and a plurality of detachable parts 302, which are spaced apart along the periphery of the liner body 300. Each detachable part 302 is provided with a fixed connection portion 3021 and a detachable connection portion 3022. Each detachable part 302 is fixedly connected to the liner body 300 via the fixed connection portion 3021. All detachable connection portions 3022 of the detachable parts 302 are used for detachable connection to the helmet shell 201 of the helmet 200.

[0170] When a plurality of locking mechanisms 202 provided in the above-mentioned embodiments are provided on the inner wall of the helmet shell 201 of the helmet 200, the plurality of detachable connecting portions 3022 of the plurality of detachable parts 302 are arranged one-to-one with the plurality of locking mechanisms 202, and the plurality of disassembly portions 1031 of the plurality of replacement parts 103 can disassemble the plurality of detachable parts 302 from the plurality of locking mechanisms 202 one-to-one. After the plurality of detachable parts 302 are disassembled, the inner lining 300 where the plurality of detachable parts 302 are located is disassembled.

[0171] In some embodiments, the locking mechanism 202 includes two locking members, each having a proximal end 2024 and a distal end 2025 that are opposed to each other along a first direction. The proximal end 2024 of one locking member is disposed between the proximal end 2024 and the distal end 2025 of the other locking member along the first direction. At least one distal end 2025 is configured to lock the replaceable liner 300. Each locking member is movable relative to the other locking member in the first direction. When the locking mechanism 202 is in a locked position, the two distal ends 2025 are spaced apart from each other. When the locking mechanism 202 is in an unlocked position, the two distal ends 2025 are positioned close to each other.

[0172] When the lifting mechanism 102 drives one of the helmet 200 and the replacement part 103 to be inserted into the other along the lifting direction, the disassembly part 1031 enters between the two proximal ends 2024 and drives the two proximal ends 2024 away from each other along the first direction, thereby switching the locking mechanism 202 from the locked position to the unlocked position; wherein the first direction is perpendicular to the lifting direction.

[0173] In some embodiments, the locking mechanism 202 includes two elastic members 2023, one elastic member 2023 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 connected between the distal end 2025 of the first locking member 2021 and the proximal end 2024 of the second locking member 2022. The detaching 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, thereby driving the two proximal ends 2024 away from each other along the first direction.

[0174] During the process of the second locking member 2022 switching from the locked position to the unlocked position along the first direction and the first locking member 2021 switching 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. Simultaneously, 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 simultaneously switches from the unlocked position to the locked position.

[0175] In some embodiments, the two proximal ends 2024 are provided with a pair of proximal force-bearing sides 2024a that are opposed to each other. The proximal force-bearing sides 2024a are arranged obliquely relative to the first direction and are symmetrically arranged along the first direction. The disassembly portion 1031 is provided with proximal force-applying portions 1031a on both sides along the first direction. The two proximal force-applying portions 1031a are symmetrically arranged along the first direction and are configured to abut against the pair of proximal force-bearing sides 2024a.

[0176] When the lifting mechanism 102 drives one of the helmet 200 and the replacement part 103 to be inserted into the other in the lifting direction, the removal portion 1031 enters between the two proximal ends 2024 and drives the two proximal ends 2024 away from each other in the first direction. The pair of proximal force-applying sides 2024a of the pair of proximal force-applying portions 1031a act on the pair of proximal force-applying sides 2024a of the two proximal ends 2024, forcing the two proximal ends 2024 away from each other. As a result, 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. The replaceable liner 300 is unlocked and can be detached from the locking mechanism 202.

[0177] In some embodiments, a through hole 30222 is provided at the center of the detachable connecting portion 3022. The through hole 30222 can be positioned directly opposite the through space 2026 between the two proximal ends 2024 of the locking mechanism 202. The edge of the through hole 30222 includes two first extensions 30222a and two second extensions 30222b that are positioned opposite each other. The first extensions 30222a are positioned farther from the axis of the through hole 30222 than the second extensions 30222b. The first extensions 30222a and the second extensions 30222b are alternately positioned along the circumference of the through hole 30222. The through hole 30222 and the through space 2026 are both used to receive the disassembly portion 1031 of the replacement component 103.

[0178] 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, and contact 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.

[0179] Furthermore, the detachment portion 1031 is provided with a detachment portion 1031c in a direction perpendicular to the first direction. The detachment portion 1031c has an inclined surface. In other words, the detachment portion 1031c and the proximal force-applying portion 1031a are spaced apart along the circumference of the detachment portion 1031. The detachment portion 1031c includes a main body portion a and a telescopic portion b. The main body portion a is connected to the detachment portion 1031 via the telescopic portion b, so that the detachment portion 1031c can be extended and retracted relative to the detachment portion 1031 in a direction perpendicular to the first direction.

[0180] Furthermore, the distance between the edge of the second extension portion 30222b and the central axis of the through-hole 30222 is less than the maximum distance between the detachment portion 1031c and the central axis of the disassembly portion 1031 when the detachment portion 1031c is in the extended state, and is greater than the maximum distance between the detachment portion 1031c and the central axis of the disassembly portion 1031 when the detachment portion 1031c is in the retracted state. The second extension portion 30222b is naturally in the extended state. Due to the provision of the inclined surface, the second extension portion 30222b can prevent the extended detachment portion 1031c from passing through the through-hole 30222 when the replacement part 103 exits the through-hole 30222, and can squeeze the detachment portion 1031c into the retracted state when the replacement part 103 enters the through-hole 30222, allowing the detachment portion 1031c to pass through the through-hole 30222.

[0181] Specifically, as the disassembly portion 1031 enters the through-hole 30222 and through-space 2026, the detachment portion 1031c is squeezed by the second expansion portion 30222b and switches from an extended state to a retracted state. Once the detachment 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 detachment portion 1031c disappears, and the detachment portion 1031c naturally switches to an extended state. Simultaneously, the two proximal force-applying portions 1031a apply a second external force to the two proximal ends 2024, driving the distal ends 2025 of the first locking member 2021 and the second locking member 2022 toward each other, thereby disassembling the replaceable liner 300. As the disassembly portion 1031 exits the through-space 2026 and through-hole 3022, the detachment portion 1031c is removed from the replaceable liner 300.

[0182] like Figures 1 to 17 , and as Figure 27 and Figure 28 As shown, in the second application embodiment, the replacement device 100 provided in the embodiment of the present application can install the lining 300 separately.

[0183] 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 external force and be in the unlocking position, and can be in the locking position under the action of the elastic force of the elastic member 2023.

[0184] The replacement device 100 includes a replacement part 103, which has an interconnected mounting portion 1032 and a storage portion. The replaceable liner 300 is provided with a detachable part 302 and is stacked on the storage portion through the detachable part 302; when the helmet 200 is installed on the replacement device 100, the mounting portion 1032, the detachable part 302 and the locking mechanism 202 are coaxially arranged along the lifting direction of the lifting mechanism 102, and the lifting mechanism 102 can drive one of the helmet 200 and the replacement part 103 to rise and fall 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 locked position to the unlocked position, and locking the detachable part 302 under the elastic force of the elastic part 2023.

[0185] The lifting mechanism 102 can drive one of the helmet 200 and the replacement part 103 to rise or fall relative to the other, forcing the detachable part 302 to act on the locking mechanism 202 and overcome the elastic force of the elastic member 2023, thereby switching the locking mechanism 202 from a locked position to an unlocked position. The elastic force of the elastic member 2023 locks the detachable part 302, thereby completing the automatic installation of the replaceable liner 300. By providing the lifting mechanism 102 in the replacement device 100, the lifting mechanism 102 can selectively drive either the helmet 200 or the replacement part 103, conveniently allowing the disposable liner 300 to be installed on the helmet 200.

[0186] In some embodiments, multiple locking mechanisms 202 are sequentially arranged along the circumference of the helmet shell 201. The replaceable liner 300 includes multiple removable parts 302, which are sequentially arranged along the circumference of the replaceable liner 300. The multiple locking mechanisms 202 are assigned one-to-one to the multiple removable parts 302 of the same replaceable liner 300. The replacement device 100 includes multiple replacement parts 103, and the multiple removable parts 302 of the same replaceable liner 300 are sleeved one-to-one onto the multiple replacement parts 103.

[0187] In some embodiments, the replaceable liner 300 includes a liner body 300 and a plurality of detachable parts 302, which are spaced apart along the periphery of the liner body 300. Each detachable part 302 is provided with a fixed connection portion 3021 and a detachable connection portion 3022. Each detachable part 302 is fixedly connected to the liner body 300 via the fixed connection portion 3021. All detachable connection portions 3022 of the detachable parts 302 are used for detachable connection to the helmet shell 201 of the helmet 200.

[0188] When multiple locking mechanisms 202 provided in the above-mentioned embodiments are provided on the inner wall of the helmet shell 201 of the helmet 200, the multiple detachable connecting parts 3022 of the multiple detachable parts 302 are squeezed and docked with the multiple locking mechanisms 202 one-to-one, and the multiple mounting parts 1032 of the multiple replacement parts 103 can be plugged into the multiple locking mechanisms 202 one-to-one, and the lining 300 where the multiple detachable parts 302 are located is installed on the locking mechanism 202.

[0189] In some embodiments, the locking mechanism 202 includes two locking members, each of which has a proximal end 2024 and a distal end 2025 opposite to each other along a first direction, and the proximal end 2024 of any locking member is arranged between the proximal end 2024 and the distal end 2025 of the other locking member along the first direction; wherein, at least one distal end 2025 is used to lock the replaceable liner 300.

[0190] The two locking members are 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 a proximal end 2024 of the first locking member 2021 and a distal end 2025 of the second locking member 2022, and the other elastic member 2023 is connected between a distal end 2025 of the first locking member 2021 and a 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 spaced apart from each other; when the locking mechanism 202 is in the unlocked position, the two distal ends 2025 are close to each other.

[0191] The lifting mechanism 102 drives one of the helmet 200 and the replacement part 103 to rise and fall relative to the other, and the mounting portion 1032 enters between the two proximal ends 2024. The lining 300 and the locking mechanism 202 are squeezed and docked along the lifting direction to force the detachable part 302 to act on the locking mechanism 202 and overcome the elastic force of the elastic part 2023, and drive the two proximal ends 2024 to clamp each other along the first direction, that is, the distal end 2025 of the first locking part 2021 and the distal end 2025 of the second locking part 2022 can approach each other at the same time along the first direction, and then switch from the unlocked position to the unlocked position, and the lining 300 is installed on the locking mechanism 202 and locked under the elastic force of the elastic part 2023.

[0192] Because two elastic members 2023 are provided in this embodiment, 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. Simultaneously, 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 switches from the unlocked position to the locked position simultaneously.

[0193] In some embodiments, the two distal ends 2025 are provided with a pair of distal end force-bearing sides 2025 facing away from each other, the distal end force-bearing sides 2025 being tilted relative to the first direction, and the pair of distal end force-bearing sides 2025 being symmetrically arranged along the first direction. The two distal end force-applying portions 30221 are provided with a pair of distal end force-applying sides 30221a facing each other, the distal end force-applying sides 30221a being tilted relative to the first direction, and the pair of distal end force-applying sides 30221a being symmetrically arranged along the first direction, and the pair of distal end force-applying sides 30221a being used to apply force to the pair of distal end force-bearing sides 2025 and overcome the elastic force of the elastic member 2023.

[0194] During the process of automatic installation of the replaceable liner 300 to the locking mechanism 202, multiple detachable parts 302 are aligned one-to-one with multiple locking mechanisms 202. The detachable connecting part 3022 in the detachable part 302 has a pair of distal force-applying parts 30221, which apply force to the force-bearing sides of two distal ends 2025 through a pair of distal force-applying sides 30221a. Since the distal force-applying sides 30221a and the force-bearing sides of the distal ends 2025 are both inclined, the two distal ends 2025 of the two locking parts can be forced to approach each other and switch from the locked position to the unlocked position.

[0195] Furthermore, the two distal force-applying parts 30221 are provided with a pair of relative second clamping structures 2025b, and the distal 2025 force-bearing side and the second clamping structure 2025b on the same distal force-applying part 30221 are arranged in sequence along the lifting direction and smoothly connected, and the two second clamping structures 2025b are clamped to a pair of second clamping structures 2025b under the elastic force of the elastic part 2023.

[0196] Since the distal force-applying side 30221a is smoothly connected to the first clamping structure 30221b, the distal force-bearing side 2025 is smoothly connected to the second clamping structure 2025b. As the movement continues, a pair of distal force-bearing sides 2025 separate from the pair of distal force-applying sides 30221a, and the two locking parts move away from each other under the elastic force of the two elastic parts 2023, and the first clamping structure 30221b and the second clamping structure 2025b are smoothly clamped.

[0197] One of the first engaging structure 30221b and the second engaging structure 2025b may be a groove structure, and the other may be a protrusion structure. For example, in some specific embodiments, the first engaging structure 30221b may be a groove structure, specifically a notch structure that penetrates the thickness of the detachable component 302. The second engaging structure 2025b may be a protrusion structure, the profile of which is precisely adapted to fit within the notch structure.

[0198] In some embodiments, the detachable connecting portion 3022 is centrally provided with a through hole 30222, which can be positioned directly opposite the through space 2026 between the two proximal ends 2024 of the locking mechanism 202. The edge of the through hole 30222 includes two opposing first extensions 30222a and two second extensions 30222b. The first extensions 30222a are positioned farther from the axis of the through hole 30222 than the second extensions 30222b. The first extensions 30222a and the second extensions 30222b are alternately positioned along the circumference of the through hole 30222. The two distal force-applying portions 30221 are positioned outside the two first extensions 30222a. The first extensions 30222a and the second extensions 30222b are both semicircular in shape. The penetration hole 30222 and the penetration space 2026 are both used for penetrating the mounting portion 1032 of the replacement component 103 .

[0199] In some embodiments, the mounting portion 1032 is provided with an anti-detachment portion 1032a on at least one radial side thereof. The anti-detachment portion 1032a comprises a main body portion a and a telescopic portion b. The main body portion a is connected to the anti-detachment portion 1032a via the telescopic portion b, allowing the anti-detachment portion 1032a to extend and retract radially relative to the mounting portion 1032. The anti-detachment portion 1032a is used to prevent an unused replaceable liner 300 from escaping the storage portion when extended, and to allow the unused replaceable liner 300 to detach from the mounting portion 1032 when the unused replaceable liner 300 is in a retracted state when mounted on the helmet 200. The telescopic portion b is provided with an inclined surface.

[0200] Based on the design of the expansion portion of the replaceable liner 300, the distance between the edge of the second expansion portion 30222b and the central axis of the through-hole 30222 is less than the maximum distance between the anti-slip portion 1032a and the central axis of the mounting portion 1032 when the anti-slip portion 1032a is in the extended state, and is greater than the maximum distance between the anti-slip portion 1032a and the central axis of the mounting portion 1032 when the anti-slip portion 1032a is in the retracted state. The natural state of the anti-slip portion 1032a is extended, in which it prevents an unused replaceable liner 300 from escaping the storage portion. Due to the provision of the inclined surface, the second expansion portion 30222b can squeeze the anti-slip portion 1032a into the retracted state when the replacement part 103 enters the through-hole 30222, allowing the anti-slip portion 1032a to pass through the through-hole 30222.

[0201] Based on the design of the above-mentioned retaining frame 203, an inclined surface corresponding to the inclined surface of the anti-slip portion 1032a is provided on the retaining frame 203. After the anti-slip portion 1032a enters the penetration hole 30222, the inclined surface of the anti-slip portion 1032a just contacts the inclined surface on the retaining frame 203 and continues to maintain a contracted state. After the liner 300 is assembled, the anti-slip portion 1032a exits the penetration space 2026 and the penetration hole 30222, and then the anti-slip portion 1032a pops out, continuing to prevent the unused replaceable liner 300 from escaping from the storage portion.

[0202] like Figures 31 to 36 In the third embodiment, the first and second embodiments can be combined. For example, the removal portion 1031 and the installation portion 1032 can be provided at opposite ends of the same replacement member 103, or can be flipped over to switch between them. Alternatively, the replacement device 100 provided in the first embodiment and the replacement device 100 provided in the second embodiment can be arranged horizontally in sequence, allowing the user to remove and install the inner lining 300.

[0203] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
