[0002] With the convenience and diversification of modern transportation, shared motorcycles, as a means of transportation that can be used at any time, have been widely popularized in urban areas. Among them, shared helmets are safety equipment used with shared motorcycles. The traffic safety regulations clearly stipulate that motorcycle riders must wear safety helmets. Different from non-shared helmets, the design of shared helmets and their linings is as consistent as possible with the use scenarios and conditions of shared motorcycles.

[0003] However, the use of existing shared helmets has the following technical problems:

[0004] First, shared helmets are often exposed to outdoor environments, and the foldable linings in them become dirty due to exposure. Users may choose not to use shared electric motorcycles due to dirt, or users may choose to use electric motorcycles but give up using helmets, which increases the probability of electric motorcycle safety accidents.

[0110] The helmet lining replacement device 100 and the replacement system 1000 provided in the embodiments of the present application are now described.

[0111] The replacement device 100 provided in the embodiment of the present application may be provided with a housing 101, and multiple mechanisms such as at least part of the lifting mechanism 102, at least part of the flipping mechanism 105, the replacement mechanism 1030, and the lifting mechanism 106 described below are provided inside the housing 101. The housing 101 has a replacement port 1011. When the helmet 200 is detachably mounted on the replacement device 100, the replacement port 1011 and the wearing port 2011 of the helmet 200 are arranged coaxially, the lifting direction of the lifting mechanism 102 is consistent with the direction of the coaxial line, and the driving axis is perpendicular to the coaxial line and the lifting direction.

[0112] See also Figures 20 to 36 ,as well as Figure 43 and Figure 49 As shown, the helmet lining replacement device 100 provided in the first embodiment of the present application includes a lifting mechanism 102 and a replacement mechanism 1030 .

[0113] Among them, the replacement device 100 is used to detachably install the helmet 200. When the helmet 200 is installed on the replacement device 100, the helmet 200 and the replacement mechanism 1030 are arranged along the height direction. The lifting mechanism 102 is transmission-connected to at least one of the helmet 200 and the replacement mechanism 1030, and can drive at least one to move relative to the other along the height direction, so that the two move from separation to contact and during the contact process, the replacement mechanism 1030 forces the helmet 200 to loosen the lining 300 and / or guide the lining 300 onto the helmet 200.

[0114] The replacement device 100 provided in the first embodiment, when the helmet 200 is installed on the replacement device 100, the lifting mechanism 102 is transmission-connected to at least one of the helmet 200 and the replacement mechanism 1030, and can drive at least one to move relative to the other in the height direction, by making the two move from separation to contact and generating interaction force in the process of contact, the replacement mechanism 1030 uses the force to force the helmet 200 to loosen the lining 300, or the replacement mechanism 1030 uses the force to guide the lining 300 to the helmet 200, so as to complete the replacement of the lining 300, which can solve the hygiene problem of the lining 300 of the helmet 200 and improve the user's willingness and experience of using the shared helmet 200.

[0115] The lifting mechanism 102 is transmission-connected to at least one of the helmet 200 and the replacement mechanism 1030, and can drive at least one to move relative to the other in the height direction, and has three implementation modes.

[0116] In the first embodiment, the lifting mechanism 102 is drivingly connected to the helmet 200, while the relative height of the replacement mechanism 1030 remains unchanged. The lifting mechanism 102 can drive the helmet 200 to move actively relative to the replacement mechanism 1030 in the height direction, including actively contacting the replacement mechanism 1030 and actively retracting in the height direction.

[0117] In the second embodiment, the lifting mechanism 102 is drivingly connected to the replacement mechanism 1030, while the relative height of the helmet 200 remains unchanged. The lifting mechanism 102 can drive the replacement mechanism 1030 to move actively relative to the helmet 200 in the height direction, including actively contacting the helmet 200 and actively retracting in the height direction.

[0118] In the third embodiment, the lifting mechanism 102 is drivingly connected to the replacement mechanism 1030, and the lifting mechanism 102 is drivingly connected to the helmet 200. The relative heights of the replacement mechanism 1030 and the helmet 200 are both variable. The lifting mechanism 102 can drive the replacement mechanism 1030 to move actively relative to the helmet 200 in the height direction, and the lifting mechanism 102 can drive the helmet 200 to move actively relative to the helmet 200 in the height direction. The two move actively relative to each other in the height direction and actively contact each other, and both can actively retract.

[0119] In the third embodiment, the replacement mechanism 1030 and the helmet 200 can be driven by different lifting mechanisms 102, or can be driven by different driving parts of the same lifting mechanism 102.

[0120] Preferably, in order to simplify the internal structure of the replacement device 100 and to make the relative movement between the replacement mechanism 1030 and the helmet 200 more convenient and reliable, the first embodiment or the second embodiment described above is preferably adopted in the embodiments of the present application.

[0121] Based on the above first embodiment, second embodiment, and third embodiment, the replacement device 100 can separately disassemble or separately install the inner lining 300 of the helmet 200, or can both complete disassembly and complete installation. As Figure 27 and Figure 28 , the replacement device 100 can separately install the inner lining 300 of the helmet 200. As Figure 29 and Figure 30 , the replacement device 100 can separately disassemble the inner lining 300 of the helmet 200. As Figure 31 and Figure 36 , the replacement device 100 can disassemble and install the inner lining 300 of the helmet 200.

[0122] In some embodiments, the replacement device 100 further includes a flipping mechanism 105, the flipping mechanism 105 has a driving axis, and the driving axis is perpendicular to the height direction. The replacement mechanism 1030 is transmission-connected to the flipping mechanism 105, and when the helmet 200 and the replacement mechanism 1030 are separated, the replacement mechanism 1030 can be flipped around the driving axis under the drive of the flipping mechanism 105.

[0123] For example, based on the first embodiment described above, the lifting mechanism 102 is transmission-connected to the helmet 200, and the replacement mechanism 1030 is transmission-connected to the flipping mechanism 105. Since the height of the driving axis remains unchanged, the replacement mechanism 1030 can be flipped, but the relative height of the replacement mechanism 1030 remains unchanged. When the replacement mechanism 1030 flips to a set angle position, the set angle position can ensure that the replacement mechanism 1030 and the helmet 200 can be in normal contact. The lifting mechanism 102 drives the helmet 200 to actively move in the height direction relative to the replacement mechanism 1030, including actively contacting the replacement mechanism 1030 in the height direction and actively retracting.

[0124] For example, based on the above-mentioned second embodiment, the lifting mechanism 102 is transmission-connected to the replacement mechanism 1030, and the replacement mechanism 1030 is transmission-connected to the flipping mechanism 105. When the replacement mechanism 1030 flips to a set angle position, the set angle position can ensure that the replacement mechanism 1030 and the helmet 200 can be in normal contact. The lifting mechanism 102 drives the replacement mechanism 1030 to actively move relative to the helmet 200 in the height direction, including actively contacting the helmet 200 in the height direction and actively retracting.

[0125] In some embodiments, the replacement mechanism 1030 has a first angle position and a second angle position, and the flip mechanism 105 can drive the replacement mechanism 1030 to switch between the first angle position and the second angle position when the helmet 200 and the replacement mechanism 1030 are separated. The replacement mechanism 1030 has a disassembly portion 1031, a guide portion 1032, and a liner 300; the disassembly portion 1031 and the guide portion 1032 are arranged on both sides of the drive axis, and the liner 300 is arranged between the disassembly portion 1031 and the guide portion 1032; wherein the disassembly portion 1031 is used to force the helmet 200 to loosen the liner 300, and the guide portion 1032 is used to guide the liner 300. When the replacement mechanism 1030 is located at the first angle position, the disassembly portion 1031 faces the helmet 200, and the lifting mechanism 102 can drive one of the helmet 200 and the replacement mechanism 1030 to move relative to the other in the height direction, and the replacement mechanism 1030 can provide a force through the disassembly portion 1031 to force the helmet 200 to release the liner 300. When the replacement mechanism 1030 is located at the second angle position, the guide portion 1032 faces the helmet 200, and the lifting mechanism 102 can drive one of the helmet 200 and the replacement mechanism 1030 to move relative to the other in the height direction, and the replacement mechanism 1030 can provide a guide through the guide portion 1032 and provide a force through the liner 300 to guide the liner 300 to the helmet 200.

[0126] For example, based on the first embodiment described above, the lifting mechanism 102 is transmission-connected to the helmet 200, the replacement mechanism 1030 is transmission-connected to the flip mechanism 105, and the relative height of the replacement mechanism 1030 remains unchanged, but the flip mechanism 105 can drive the replacement mechanism 1030 to switch between the first angle position and the second angle position when the helmet 200 and the replacement mechanism 1030 are separated. When the replacement mechanism 1030 is at the first angle position, the disassembly portion 1031 thereof faces the helmet 200, and the lifting mechanism 102 can drive the helmet 200 to move relative to the disassembly portion 1031 in the height direction, and can actively contact the disassembly portion 1031 and actively withdraw from the disassembly portion 1031. During the contact process, the disassembly portion 1031 provides a force to force the helmet 200 to loosen the liner 300. When the replacement mechanism 1030 is located at the second angle position, the guide part 1032 thereof is facing the helmet 200, and the lifting mechanism 102 can drive the helmet 200 to move relative to the guide part 1032 along the height direction, and can actively contact the guide part 1032 and actively withdraw from the guide part 1032. During the contact process, the guide part 1032 provides guidance and the lining 300 provides force, so that the lining 300 is guided to the helmet 200.

[0127] For example, based on the above second embodiment, the lifting mechanism 102 is drivingly connected to the replacement mechanism 1030, and the replacement mechanism 1030 is drivingly connected to the flipping mechanism 105. The relative height of the helmet 200 remains unchanged, and the flipping mechanism 105 can drive the replacement mechanism 1030 to switch between a first angular position and a second angular position when the helmet 200 and the replacement mechanism 1030 are separated. When the replacement mechanism 1030 is in the first angular position, the disassembly part 1031 therein faces the helmet 200, and the lifting mechanism 102 can drive the replacement mechanism 1030 to move relative to the helmet 200 in the height direction. The disassembly part 1031 can actively contact the helmet 200 and actively withdraw from the helmet 200, and provide a force through the disassembly part 1031 during the contact process to force the helmet 200 to release the inner lining 300. When the replacement mechanism 1030 is in the second angular position, the guiding part 1032 therein faces the helmet 200, and the lifting mechanism 102 can drive the replacement mechanism 1030 to move relative to the helmet 200 in the height direction. The guiding part 1032 can actively contact the helmet 200 and actively withdraw from the helmet 200, and provide guidance through the guiding part 1032 and provide a force through the inner lining 300 during the contact process to guide the inner lining 300 onto the helmet 200.

[0128] In some embodiments, the replacement device 100 further includes a detachable component 104 for detachably mounting the helmet 200, and the detachable component 104 is drivingly connected to the lifting mechanism 102. The detachable component 104 has a first height position and a second height position, and can be switched between the first height position and the second height position under the drive of the lifting mechanism 102. Among them, when in the first height position, the helmet 200 and the replacement mechanism 1030 are separated in the height direction; during the process of switching from the first height position to the second height position, the replacement mechanism 1030 contacts the helmet 200 and provides a force to the helmet 200; when in the second height position, the replacement mechanism 1030 remains in contact with the helmet 200 and the helmet 200 releases the inner lining 300 and / or the inner lining 300 guiding is completed.

[0129] Based on the above first embodiment, the detachable component 104 is drivingly connected to the lifting mechanism 102, and the helmet 200 is detachably mounted on the detachable component 104. Therefore, the helmet 200 is drivingly connected to the lifting mechanism 102 through the detachable component 104, while the relative height of the replacement mechanism 1030 remains unchanged. The lifting mechanism 102 can drive the helmet 200 to switch between a first height position and a second height position in the height direction. The helmet 200 can move actively relative to the replacement mechanism 1030, including switching from the first height position to the second height position in the height direction to actively contact the replacement mechanism 1030, and switching from the second height position to the first height position in the height direction to actively retreat.

[0130] Alternatively, in the embodiment based on the first embodiment described above in combination with the flipping mechanism 105, the detachable component 104 is drivingly connected to the lifting mechanism 102, and the helmet 200 is detachably mounted on the detachable component 104. Therefore, the helmet 200 is drivingly connected to the lifting mechanism 102 through the detachable component 104, while the replacement mechanism 1030 is drivingly connected to the flipping mechanism 105 and the height of the driving axis remains unchanged. Therefore, the relative height of the replacement mechanism 1030 remains unchanged, and the flipping mechanism 105 can drive the replacement mechanism 1030 to switch between the first angular position and the second angular position when the detachable component 104 is in the first height position.

[0131] Specifically, when the detachable component 104 is in the first height position, the flipping mechanism 105 drives the replacement mechanism 1030 to switch to the first angular position, where the disassembly part 1031 faces the helmet 200. The lifting mechanism 102 drives the detachable component 104 to switch from the first height position to the second height position, and the helmet 200 moves towards the disassembly part 1031 in the height direction and can actively contact the disassembly part 1031. During the contact process, the disassembly part 1031 provides a force to force the helmet 200 to release the inner lining 300. The lifting mechanism 102 drives the detachable component 104 to switch from the second height position to the first height position, and the helmet 200 exits the disassembly part 1031 in the height direction, thus completing a single disassembly of the disposable inner lining 300.

[0132] At this time, the detachable component 104 is in the first height position, and the flipping mechanism 105 drives the replacement mechanism 1030 to switch from the first angular position to the second angular position, where the guiding part 1032 faces the helmet 200. The lifting mechanism 102 drives the detachable component 104 to switch from the first height position to the second height position, and the helmet 200 moves towards the guiding part 1032 in the height direction and can actively contact the guiding part 1032. During the contact process, the guiding part 1032 provides guidance and the inner lining 300 provides a force to guide the inner lining 300 onto the helmet 200. The lifting mechanism 102 drives the detachable component 104 to switch from the second height position to the first height position, and the helmet 200 exits the guiding part 1032 in the height direction, thus completing a single installation of the disposable inner lining 300. The replacement of the disposable inner lining 300 is completed through a single disassembly and a single installation.

[0133] Among them, preferably, when the helmet 200 is detachably mounted on the detachable component 104, the helmet 200 is located above the replacement mechanism 1030. Therefore, the first height position is higher than the second height position. In other alternative ways, when the helmet 200 is detachably mounted on the detachable component 104, the helmet 200 is located below the replacement mechanism 1030. Therefore, the first height position is lower than the second height position.

[0134] In the embodiment of the second implementation mode combined with the flipping mechanism 105 described above, the replacement device 100 further includes a lifting frame, and the flipping mechanism 105 is mounted on the lifting frame. The lifting frame is in transmission connection with the lifting mechanism 102, and the lifting mechanism 102 can synchronously drive the flipping mechanism 105 and the replacement mechanism 1030 to move up and down relative to the helmet 200 through the lifting frame. The replacement mechanism 1030 has a third height position and a fourth height position and can be switched between the third height position and the fourth height position under the drive of the lifting mechanism 102. Among them, when in the third height position, the helmet 200 and the replacement mechanism 1030 are separated in the height direction; during the process of switching from the third height position to the fourth height position, the replacement mechanism 1030 contacts the helmet 200 and provides a force to the helmet 200; when in the fourth height position, the replacement mechanism 1030 keeps contacting the helmet 200 and the helmet 200 releases the inner liner 300 and / or the inner liner 300 is completely guided and installed.

[0135] Specifically, when the replacement mechanism 1030 is in the third height position, the flipping mechanism 105 drives the replacement mechanism 1030 to switch to the first angular position, and the disassembly part 1031 faces the helmet 200. The lifting mechanism 102 drives the replacement mechanism 1030 to switch from the third height position to the fourth height position, and the disassembly part 1031 moves toward the helmet 200 in the height direction, and can actively contact the helmet 200, and forces the helmet 200 to release the inner liner 300 through the force during the contact process. The lifting mechanism 102 drives the replacement mechanism 1030 to switch from the fourth height position to the third height position, and the disassembly part 1031 exits the helmet 200 in the height direction, thus completing the single disassembly of the disposable inner liner 300.

[0136] At this time, when the replacement mechanism 1030 is in the third height position, the flipping mechanism 105 drives the replacement mechanism 1030 to switch from the first angular position to the second angular position, and the guiding part 1032 faces the helmet 200. The lifting mechanism 102 drives the replacement mechanism 1030 to switch from the third height position to the fourth height position, and the guiding part 1032 moves toward the helmet 200 in the height direction, and can actively contact the helmet 200, provides guidance during the contact process and provides a force through the inner liner 300 to guide and install the inner liner 300 onto the helmet 200. The lifting mechanism 102 drives the replacement mechanism 1030 to switch from the fourth height position to the third height position, and the guiding part 1032 exits the helmet 200 in the height direction, thus completing the single installation of the disposable inner liner 300. The replacement of the disposable inner liner 300 is completed through single disassembly and single installation.

[0137] Preferably, when the helmet 200 is detachably mounted on the replacement device 100, the helmet 200 is located above the replacement mechanism 1030, so the third height position is lower than the fourth height position. In other alternative ways, when the helmet 200 is detachably mounted on the replacement device 100, the helmet 200 is located below the replacement mechanism 1030, so the third height position is higher than the fourth height position.

[0138] In some specific embodiments, the lifting frame has a bottom and two sides. The two sides are oppositely arranged along the driving axis, and the driving axis and the bottom are spaced apart in the height direction. The flipping mechanism 105 is mounted on the two sides, and the bottom is drivingly connected to the lifting mechanism 102; the replacement mechanism 1030 is arranged between the bottom and the two sides and can be flipped relative to the lifting frame under the drive of the flipping mechanism 105.

[0139] For example, the lifting frame can be a U-shaped frame, the opening of the U-shaped frame is arranged opposite to the replacement opening 1011, the replacement mechanism 1030 is arranged inside the frame of the U-shaped frame, the flipping mechanism 105 is mounted on the two sides, the two sides are respectively slidably connected to the housing 101, and the lifting end of the lifting mechanism 102 is connected to the bottom of the U-shaped frame. In this way, the characteristics of the U-shaped frame are cleverly utilized. The two sides are respectively slidably connected to the housing 101 to provide a guide rail and guiding function for the lifting mechanism 102 to drive the flipping mechanism 105 and the replacement mechanism 1030 to lift. The bottom wall is used as the part connected to the lifting end of the lifting mechanism 102. The functions of the bottom and the sides do not interfere with each other, and the opening of the U-shaped frame is utilized. The disassembly part 1031 and the guiding part 1032 on the replacement mechanism 1030 can be respectively located at the opening of the U-shaped frame during the angle switching, which is convenient for the guiding part 1032 and the disassembly part 1031 to contact the helmet 200 respectively.

[0140] In this embodiment, the number of the lifting mechanisms 102 can be set to one, which can reduce the manufacturing cost of the replacement device 100. Among them, the lifting mechanism 102 can be a cylinder mechanism, a lead screw driving mechanism or other mechanisms that can achieve linear driving. In this embodiment, since the lifting mechanism 102 is arranged inside the housing 101 and is always connected to the replacement mechanism 1030 without being drivingly connected to the helmet 200 that needs to be frequently disassembled and assembled, the damage probability of the lifting mechanism 102 can be reduced.

[0141] With respect to the above-mentioned solution in which the helmet 200, the replacement mechanism 1030, and the lifting mechanism 102 are sequentially arranged along the lifting direction, in other specific embodiments, the replacement mechanism 1030 and the lifting mechanism 102 can be sequentially arranged along a direction perpendicular to the lifting direction, and the lifting mechanism 102 is connected to the replacement mechanism 1030 and can drive the replacement mechanism 1030 to rise and fall relative to the helmet 200. In this way, the lifting mechanism 102 is arranged on the side of the replacement mechanism 1030 along the lifting direction, and the lifting mechanism 102 drives the replacement mechanism 1030 to rise and fall relative to the helmet 200.

[0142] In this embodiment, the lifting mechanism 102 can be arranged on one side or both sides of the lifting direction according to specific needs. The arrangement on both sides can ensure that the replacement mechanism 1030 is lifted and lowered smoothly along the lifting direction. Among them, the lifting mechanism 102 can be a cylinder mechanism, or a screw drive mechanism or other mechanism that can realize linear drive. When the lifting mechanism 102 is arranged on both sides of the lifting direction, the two cylinder mechanisms or the two screw drive mechanisms are arranged in parallel. In this embodiment, since the lifting mechanism 102 is arranged inside the shell 101, it is always connected to the replacement mechanism 1030, and there is no need to be connected to the helmet 200 that requires high-frequency disassembly and assembly, so the probability of damage to the lifting mechanism 102 can also be reduced.

[0143] like Figure 48 and Figure 49 As shown, different from the above-mentioned solution of combining the lifting mechanism 102 with the flipping mechanism 105, the embodiment of the present application also provides a solution of combining the lifting mechanism 102 with the translation mechanism 107. In some embodiments, the replacement device 100 further includes a detachable component 104, and the detachable component 104 is used for detachably installing the helmet 200. The replacement device 100 further includes a translation mechanism 107, and the translation mechanism 107 has a translation path, and the translation path is perpendicular to the height direction.

[0144] Among them, the detachable component 104 is transmission-connected to the lifting mechanism 102 and the two constitute a translation assembly, the replacement mechanism 1030 and one of the translation assemblies are transmission-connected to the translation mechanism 107, and the translation mechanism 107 can drive the one to reciprocate along the translation path when the helmet 200 and the replacement mechanism 1030 are separated.

[0145] Alternatively, the replacement mechanism 1030 is transmission-connected to the lifting mechanism 102 and the two constitute a translation assembly, and one of the detachable component 104 and the translation assembly is transmission-connected to the translation mechanism 107, and the translation mechanism 107 can drive one of them to reciprocate along the translation path when the helmet 200 and the replacement mechanism 1030 are separated.

[0146] Among them, the translation mechanism 107 has a translation end, and can drive the helmet 200 or the replacement mechanism 1030 to translate in the horizontal direction through the translation end. The translation path refers to the moving path of the translation end, that is, the translation path of the helmet 200 or the replacement mechanism 1030. The translation path can be a straight line path or an arc path. The two ends of the translation path can be understood as the first horizontal position and the second horizontal position.

[0147] like Figure 50 As shown, the translation path of the translation mechanism 107 is a straight line, and the translation end is connected to the helmet 200 by transmission, so that the helmet 200 can be driven to translate back and forth along the straight line. Alternatively, the translation path of the translation mechanism 107 is a straight line, and the translation end is connected to the replacement mechanism 1030 by transmission, so that the replacement mechanism 1030 can be driven to translate back and forth along the straight line. In this case, the translation mechanism 107 can be a cylinder mechanism, a screw drive mechanism, or other mechanisms that can achieve linear translation.

[0148] like Figure 51 As shown, the translation path of the translation mechanism 107 is an arc, and the translation end is connected to the helmet 200 by transmission, so that the helmet 200 can be driven to translate back and forth along the arc. Alternatively, the translation path of the translation mechanism 107 is an arc, and the translation end is connected to the replacement mechanism 1030 by transmission, so that the replacement mechanism 1030 can be driven to translate back and forth along the arc. In this case, the translation mechanism 107 can be driven by the rotating shaft to rotate to a set angle, and the replacement mechanism 1030 is radially arranged outside the rotating shaft, and is driven by the rotating shaft to translate the set angle in the form of an arc in the circumferential direction.

[0149] In a first specific embodiment, the detachable component 104 is connected to the lifting mechanism 102 by transmission, and the lifting mechanism 102 can drive the detachable component 104 to rise and fall, thereby driving the helmet 200 to rise and fall, and the detachable component 104 has a first height position and a second height position, and can switch between the first height position and the second height position. Further, the replacement mechanism 1030 is connected to the translation mechanism 107 by transmission, and the translation mechanism 107 can drive the replacement mechanism 1030 to reciprocate along the translation path when the helmet 200 and the replacement mechanism 1030 are separated, that is, to switch between the first horizontal position and the second horizontal position.

[0150] More specifically, when the detachable component 104 is at the first height position, the translation mechanism 107 drives the replacement mechanism 1030 to switch to the first horizontal position, wherein the disassembly portion 1031 faces the helmet 200, and the lifting mechanism 102 drives the detachable component 104 to switch from the first height position to the second height position, and the helmet 200 moves toward the disassembly portion 1031 along the height direction, and can actively contact the disassembly portion 1031. During the contact process, the disassembly portion 1031 provides a force to force the helmet 200 to release the liner 300. The lifting mechanism 102 drives the detachable component 104 to switch from the second height position to the first height position, and the helmet 200 exits the disassembly portion 1031 along the height direction, thus completing the single disassembly of the disposable liner 300.

[0151] At this time, the detachable component 104 is at the first height position, and the translation mechanism 107 drives the replacement mechanism 1030 to switch from the first horizontal position to the second horizontal position, wherein the guide portion 1032 is facing the helmet 200, and the lifting mechanism 102 drives the detachable component 104 to switch from the first height position to the second height position, and the helmet 200 moves toward the guide portion 1032 along the height direction, and can actively contact the guide portion 1032. During the contact process, the guide portion 1032 provides guidance and the liner 300 provides a force, so that the liner 300 is guided to the helmet 200. The lifting mechanism 102 drives the detachable component 104 to switch from the second height position to the first height position, and the helmet 200 exits the guide portion 1032 along the height direction, thus completing the single installation of the disposable liner 300, and completing the replacement of the disposable liner 300 through single removal and single installation.

[0152] In the second specific embodiment, the detachable component 104 is connected to the lifting mechanism 102 by transmission, and the lifting mechanism 102 can drive the detachable component 104 to rise and fall, thereby driving the helmet 200 to rise and fall, and the detachable component 104 has a first height position and a second height position, and can switch between the first height position and the second height position, and the detachable component 104 and the lifting mechanism 102 constitute a translation assembly. Further, the translation assembly is connected to the translation mechanism 107 by transmission, and the translation mechanism 107 can drive the translation assembly to reciprocate along the translation path when the helmet 200 and the replacement mechanism 1030 are separated, that is, to switch between the first horizontal position and the second horizontal position.

[0153] More specifically, when the detachable component 104 is at the first height position, the translation mechanism 107 drives the translation assembly to switch to the first horizontal position. At this time, the disassembly portion 1031 in the replacement mechanism 1030 is facing the helmet 200. The lifting mechanism 102 drives the detachable component 104 to switch from the first height position to the second height position. The helmet 200 moves toward the disassembly portion 1031 along the height direction, and can actively contact the disassembly portion 1031. During the contact process, the disassembly portion 1031 provides a force to force the helmet 200 to release the liner 300. The lifting mechanism 102 drives the detachable component 104 to switch from the second height position to the first height position, and the helmet 200 exits the disassembly portion 1031 along the height direction, thus completing the single disassembly of the disposable liner 300.

[0154] At this time, the detachable component 104 is at the first height position, and the translation mechanism 107 drives the translation assembly to switch from the first horizontal position to the second horizontal position. At this time, the guide portion 1032 in the replacement mechanism 1030 is facing the helmet 200. The lifting mechanism 102 drives the detachable component 104 to switch from the first height position to the second height position. The helmet 200 moves toward the guide portion 1032 in the height direction and can actively contact the guide portion 1032. During the contact process, the guide portion 1032 provides guidance and the liner 300 provides a force, so that the liner 300 is guided to the helmet 200. The lifting mechanism 102 drives the detachable component 104 to switch from the second height position to the first height position, and the helmet 200 exits the guide portion 1032 in the height direction, thus completing the single installation of the disposable liner 300, and completing the replacement of the disposable liner 300 through single removal and single installation.

[0155] In the third specific embodiment, the replacement mechanism 1030 is connected to the lifting mechanism 102 by transmission, and the lifting mechanism 102 can drive the replacement mechanism 1030 to rise and fall, and the replacement mechanism 1030 has a third height position and a fourth height position, and can switch between the third height position and the fourth height position. The detachable component 104 is connected to the translation mechanism 107 by transmission, and the translation mechanism 107 can drive the detachable component 104 to reciprocate along the translation path when the helmet 200 and the replacement mechanism 1030 are separated, that is, to switch between the first horizontal position and the second horizontal position.

[0156] More specifically, when the replacement mechanism 1030 is at the third height position, the translation mechanism 107 drives the detachable assembly 104 to switch to the first horizontal position, the detachment portion 1031 in the replacement mechanism 1030 faces the helmet 200, and the lifting mechanism 102 drives the replacement mechanism 1030 to switch from the third height position to the fourth height position, then the detachment portion 1031 moves toward the helmet 200 along the height direction, and can actively contact the helmet 200, and during the contact process, the helmet 200 is forced to release the liner 300 through the force. The lifting mechanism 102 drives the replacement mechanism 1030 to switch from the fourth height position to the third height position, and the detachment portion 1031 withdraws from the helmet 200 along the height direction, thus completing the single detachment of the disposable liner 300.

[0157] At this time, the replacement mechanism 1030 is at the third height position, the translation mechanism 107 drives the detachable assembly 104 to switch from the first horizontal position to the second horizontal position, the guide portion 1032 in the replacement mechanism 1030 faces the helmet 200, the lifting mechanism 102 drives the replacement mechanism 1030 to switch from the third height position to the fourth height position, and the guide portion 1032 moves toward the helmet 200 along the height direction, and can actively contact the helmet 200, provide guidance during the contact process, and provide a force through the liner 300 to guide the liner 300 to the helmet 200. The lifting mechanism 102 drives the replacement mechanism 1030 to switch from the fourth height position to the third height position, and the guide portion 1032 withdraws from the helmet 200 along the height direction, thus completing the single installation of the disposable liner 300, and completing the replacement of the disposable liner 300 through a single removal and a single installation.

[0158] In the fourth specific embodiment, the replacement mechanism 1030 is connected to the lifting mechanism 102 by transmission, and the lifting mechanism 102 can drive the replacement mechanism 1030 to rise and fall, and the replacement mechanism 1030 has a third height position and a fourth height position, and can switch between the third height position and the fourth height position, and the replacement mechanism 1030 and the lifting mechanism 102 constitute a translation assembly. The translation assembly is connected to the translation mechanism 107 by transmission, and the translation mechanism 107 can drive the translation assembly to reciprocate along the translation path when the helmet 200 and the replacement mechanism 1030 are separated, that is, to switch between the first horizontal position and the second horizontal position.

[0159] More specifically, when the replacement mechanism 1030 is at the third height position, the translation mechanism 107 drives the translation assembly to switch to the first horizontal position, the disassembly portion 1031 in the replacement mechanism 1030 faces the helmet 200, and the lifting mechanism 102 drives the replacement mechanism 1030 to switch from the third height position to the fourth height position, then the disassembly portion 1031 moves toward the helmet 200 along the height direction, and can actively contact the helmet 200, and during the contact process, the helmet 200 is forced to release the liner 300 through the force. The lifting mechanism 102 drives the replacement mechanism 1030 to switch from the fourth height position to the third height position, and the disassembly portion 1031 withdraws from the helmet 200 along the height direction, thus completing the single disassembly of the disposable liner 300.

[0160] At this time, the replacement mechanism 1030 is at the third height position, the translation mechanism 107 drives the translation assembly to switch from the first horizontal position to the second horizontal position, the guide portion 1032 in the replacement mechanism 1030 is facing the helmet 200, the lifting mechanism 102 drives the replacement mechanism 1030 to switch from the third height position to the fourth height position, and the guide portion 1032 moves toward the helmet 200 along the height direction, and can actively contact the helmet 200, provide guidance during the contact process, and provide a force through the liner 300 to guide the liner 300 to the helmet 200. The lifting mechanism 102 drives the replacement mechanism 1030 to switch from the fourth height position to the third height position, and the guide portion 1032 withdraws from the helmet 200 along the height direction, thus completing the single installation of the disposable liner 300, and completing the replacement of the disposable liner 300 through a single removal and a single installation.

[0161] Preferably, the detachable component 104 is transmission-connected to the lifting mechanism 102, the replacement mechanism 1030 is transmission-connected to the translation mechanism 107, and the replacement mechanism 1030 has the above-mentioned first horizontal position and second horizontal position and can switch between the first horizontal position and the second horizontal position.

[0162] The helmet liner replacement system 1000 provided in the embodiment of the present application based on the replacement device 100 of the first embodiment includes the replacement device 100 of the first embodiment and a helmet 200. The helmet 200 is detachably mounted on the replacement device 100, and the wearing port 2011 and the replacement port 1011 are coaxially arranged in the height direction.

[0163] In some embodiments, based on the replacement system 1000 of the replacement device 100 in the above first embodiment, the replacement mechanism 1030 has a disassembly part 1031 and / or a guiding part 1032, and a lining 300. The helmet 200 is provided with a locking mechanism 202, and the locking mechanism 202 includes an elastic member 2023. The locking mechanism 202 has a locking position and an unlocking position, and is held in the locking position under the elastic force of the elastic member 2023. When the lifting mechanism 102 drives at least one of the helmet 200 and the replacement mechanism 1030 to move relative to the other along the height direction, the disassembly part 1031 can overcome the elastic force of the elastic member 2023 and switch the locking mechanism 202 from the locking position to the unlocking position, so as to force the helmet 200 to release the lining 300. And / or, when the lifting mechanism 102 drives at least one of the helmet 200 and the replacement mechanism 1030 to move relative to the other along the height direction, the lining 300 can overcome the elastic force of the elastic member 2023 under the guidance of the guiding part 1032 and switch the locking mechanism 202 from the locking position to the unlocking position, so as to be guided onto the helmet 200.

[0164] The beneficial effects of the replacement system 1000 of the replacement device 100 based on the above first embodiment compared with the prior art are the same as the beneficial effects of the helmet lining replacement device 100 provided in the above first embodiment compared with the prior art, and will not be elaborated here.

[0165] Referring to Figures 20 to 36 and Figure 43 and Figure 49 and Figure 50 and Figure 51 As shown in

[0166] The helmet lining replacement device 100 provided in the second embodiment of the present application includes a flipping mechanism 105 and a replacement mechanism 1030. The replacement mechanism 1030 and the replacement port 1011 of the housing 101 are arranged in coaxial order. The inner side of the wearing port 2011 of the helmet 200 is used for detachably installing the lining 300.

[0167] The second embodiment provides a helmet liner replacement device 100, wherein the replacement mechanism 1030 can be flipped around its drive axis under the drive of the flip mechanism 105. When the replacement mechanism 1030 is located at a first angle position, the disassembly portion 1031 thereof faces the replacement port 1011, and the used liner 300 can be removed from the inner side of the wearing port 2011 of the helmet 200 through the disassembly portion 1031. When the replacement mechanism 1030 is located at a second angle position, the guide portion 1032 thereof faces the replacement port 1011, and the unused liner 300 can be guided to the inner side of the wearing port 2011 of the helmet 200 through the guide portion 1032. In this way, by flipping the replacement mechanism 1030 through the flipping mechanism 105, the angular position of the disassembly part 1031 and the installation guide part 1032 in the replacement mechanism 1030 can be switched, so that the installation and disassembly of the lining 300 of the helmet 200 can be completed on the same replacement port 1011, thereby solving the hygiene problem of the lining 300 of the helmet 200.

[0168] The replacement device 100 provided in the second embodiment of the present application can be used alone to realize the removal and installation of the liner 300 on the same replacement port 1011. For example, the user can manually drive the helmet 200 to move relative to the replacement mechanism 1030 along the coaxial direction.

[0169] The replacement device 100 provided in the second embodiment of the present application can also be used in combination with the replacement device 100 provided in the first embodiment. For example, the helmet 200 is connected to the lifting mechanism 102 by means of the detachable component 104, and the replacement mechanism 1030 is connected to the flipping mechanism 105 by means of the transmission. Alternatively, the replacement mechanism 1030 is connected to the flipping mechanism 105 by means of the transmission, and the replacement mechanism 1030 is connected to the lifting mechanism 102 by means of the transmission.

[0170] In some embodiments, the disassembly portion 1031 and the installation guiding portion 1032 are coaxially disposed and opposite to each other along the direction of the coaxial line, and a switching angle between the first angular position and the second angular position is a straight angle.

[0171] For example, if the replacement mechanism 1030 rotates a flat angle in the clockwise direction, it will rotate from the first angular position to the second angular position; if the replacement mechanism 1030 rotates a flat angle in the counterclockwise direction, it will rotate from the second angular position to the first angular position; or if the replacement mechanism 1030 continues to rotate a flat angle in the clockwise direction, it will rotate from the second angular position to the first angular position.

[0172] In some embodiments, the replacement part 103 is a rod. The two end portions of the replacement part 103 are respectively a disassembly part 1031 and a guiding and installing part 1032. The rod region on the replacement part 103 between the two end portions is a storage part. The regions on the plurality of storage parts close to the plurality of disassembly parts 1031 are used for multi-point socket connection of the same used inner liner 300 removed by the disassembly part 1031, and the regions on the plurality of storage parts close to the plurality of guiding and installing parts 1032 are used for multi-point socket connection of the same unused inner liner 300.

[0173] More specifically, the replacement mechanism 1030 includes a plurality of replacement parts 103. The plurality of replacement parts 103 are arranged in parallel at intervals. The replacement part 103 has a disassembly part 1031 and a guiding and installing part 1032. The plurality of replacement parts 103 are equal in number and arranged at intervals on both sides of the driving axis. The plurality of replacement parts 103 are respectively connected to the flipping mechanism 105 and can be driven by the flipping mechanism 105 to flip synchronously. Among them, when the replacement mechanism 1030 is in the first angular position, the plurality of disassembly parts 1031 face the replacement port 1011 and the plurality of guiding and installing parts 1032 face away from the replacement port 1011. When the replacement mechanism 1030 is in the second angular position, the plurality of guiding and installing parts 1032 face the replacement port 1011 and the plurality of disassembly parts 1031 face away from the replacement port 1011.

[0174] In other embodiments, the replacement part 103 includes a disassembly part 1031 and a guiding and installing part 1032 that are arranged at intervals and perpendicular to each other. The replacement mechanism 1030 includes a plurality of replacement parts 103. The plurality of disassembly parts 1031 of the plurality of replacement parts 103 are arranged at intervals along the same circumferential direction with the first center line as the center, and the plurality of guiding and installing parts 1032 of the plurality of replacement parts 103 are arranged at intervals along the same circumferential direction with the second center line as the center. The first center line and the second center line are perpendicular to each other, and the switching angle between the first angular position and the second angular position is a right angle.

[0175] For example, if the replacement mechanism 1030 rotates clockwise by a right angle, it rotates from the first angular position to the second angular position. If the replacement mechanism 1030 rotates counterclockwise by a right angle, it rotates from the second angular position to the first angular position.

[0176] In some embodiments, the replacement device 100 includes a first bracket 1081 and a second bracket 1082. The first bracket 1081 and the second bracket 1082 are spaced along the driving axis and are fixed relative to the housing 101. The replacement mechanism 1030 is disposed between the first bracket 1081 and the second bracket 1082. The replacement mechanism 1030 has two transfer structures 1061d spaced along the driving axis. The flipping mechanism 105 includes a flipper 1051 and a flipping shaft 1052 coaxially connected to the flipper 1051. The flipper 1051 is disposed outside the first bracket 1081. The flipping shaft 1052 rotatably penetrates through the first bracket 1081. The end of the flipping shaft 1052 located inside the first bracket 1081 is coaxial and drivingly connected to one of the transfer structures 1061d. The other transfer structure 1061d is rotatably arranged on the second bracket 1082. In this way, the purpose of driving the replacement mechanism 1030 to flip between the first angular position and the second angular position by the flipping mechanism 105 can be achieved. Wherein, a coupling can be provided between the flipping shaft 1052 and one of the transfer structures 1061d for fixing and connecting.

[0177] For example, both the first bracket 1081 and the second bracket 1082 can be plate members. The two plate members are parallel and spaced along the driving axis. The replacement mechanism 1030 is disposed between the two plate members. The flipper 1051 can be disposed outside the housing 101. Its flipping shaft 1052 can penetrate through the wall thickness of the housing 101 and pass through the first bracket 1081 to be connected to one of the transfer structures 1061d.

[0178] In some embodiments, the replacement device 100 further includes a first position detecting device 1083 and a second position detecting device 1084. The first position detecting device 1083 and the second position detecting device 1084 are spaced along a common axis and are symmetric about the driving axis. Any one of the transfer structures 1061d is provided with a triggering structure 1061e. The triggering structure 1061e is used to trigger the first position detecting device 1083 and the second position detecting device 1084 respectively when the flipping mechanism 105 is in the first angular position and the second angular position for detecting whether the replacement mechanism 1030 is in the first angular position or the second angular position.

[0179] In some embodiments, the first bracket 1081 is provided with a first opening 1081a and a second opening 1081b, the first opening 1081a and the second opening 1081b are spaced apart along a coaxial line and are symmetrical about the drive axis. The flipping machine 1051 has a housing, the housing has a first extension end 1051a and a second extension end 1051b, the first extension end 1051a and the second extension end 1051b are spaced apart along a coaxial line and are symmetrical about the drive axis. Moreover, the first extension end 1051a and the second extension end 1051b are one-to-one inserted into the first opening 1081a and the second opening 1081b, and the first position detection device 1083 and the second position detection device 1084 are one-to-one disposed on the side surface of the first extension end 1051a and the second extension end 1051b located on the inner side of the first bracket 1081.

[0180] The first extension end 1051a and the second extension end 1051b are fixed respectively through the first opening 1081a and the second opening 1081b on the first bracket 1081, so that the first position detection device 1083 and the second position detection device 1084 can be conveniently and stably arranged on the inner side of the first bracket 1081, so as to facilitate the contact between the first position detection device 1083 and the second position detection device 1084 respectively during the rotation of the trigger structure 1061e around the driving axis.

[0181] The helmet lining replacement system 1000 provided in the embodiment of the present application based on the replacement device 100 of the second embodiment described above includes the helmet lining replacement device 100 as described above, and a helmet 200 that can be detachably mounted on the replacement port 1011 of the replacement device 100. When the replacement mechanism 1030 in the replacement device 100 is located at a first angle position, the disassembly portion 1031 of the replacement mechanism 1030 can disassemble the used lining 300 from the inner side of the wearing port 2011 of the helmet 200. When the replacement mechanism 1030 in the replacement device 100 is located at a second angle position, the guide portion 1032 of the replacement mechanism 1030 can guide the unused lining 300 to the inner side of the wearing port 2011.

[0182] In some embodiments, the replacement device 100 further includes a lifting mechanism 102 disposed in the housing 101, and the flip mechanism 105 and the replacement mechanism 1030 constitute a lifted assembly. One of the helmet 200 and the lifted assembly is connected to the lifting mechanism 102 by transmission, and is configured to be able to lift relative to the other along a coaxial line under the drive of the lifting mechanism 102. Moreover, when the replacement mechanism 1030 is located at a first angle position, the helmet 200 and the lifted assembly move toward each other and contact each other so that the removal part 1031 removes the used liner 300 from the inner side of the wearing opening 2011 of the helmet 200; when the replacement mechanism 1030 is located at a second angle position, the helmet 200 and the lifted assembly move toward each other and contact each other so that the guide part 1032 guides the unused liner 300 to the inner side of the wearing opening 2011.

[0183] In some embodiments, the replacement device 100 further includes a detachable component 104 for detachably mounting the helmet 200. The detachable component 104 is drivingly connected to the lifting mechanism 102, and the lifting mechanism 102 can drive the helmet 200 to move up and down along the coaxial direction through the detachable component 104, so that when the replacement mechanism 1030 is in the first angular position, the helmet 200 can move towards the disassembly part 1031 and contact it or actively withdraw from the disassembly part 1031, and when the replacement mechanism 1030 is in the second angular position, the helmet 200 can move towards the guiding part 1032 and contact it or actively withdraw from the guiding part 1032.

[0184] The beneficial effects of the replacement system 1000 of the helmet inner lining replacement device 100 provided by the embodiments of the present application compared with the prior art are the same as those of the helmet inner lining replacement device 100 provided by the second embodiment of the present application compared with the prior art, and will not be elaborated here.

[0185] Refer to Figures 43 to 47 and Figures 52 to 58 As shown, the helmet inner lining replacement device 100 provided by the third embodiment of the present application includes a lifting mechanism 106, a replacement part 103, and a replaceable inner lining 300. The replacement part 103 has a storage part and a guiding part 1032 arranged in sequence and smoothly connected. The inner lining 300 is movably sleeved on the storage part, and the guiding part 1032 is used to guide the inner lining 300 onto the helmet 200. The lifting mechanism 106 has a lifting output member 1065, and the inner lining 300 is supported on the lifting output member 1065 and is configured to be pushed up at least the thickness distance of one inner lining 300 along the direction from the storage part to the guiding part 1032 under the push of the lifting mechanism 106.

[0186] Since the replacement part 103 has a storage part and a guiding part 1032 arranged in sequence and smoothly connected, the inner lining 300 is movably sleeved on the storage part, and the inner lining 300 is supported on the lifting output member 1065. During the process of the lifting mechanism 106 pushing the lifting output member 1065, the inner lining 300 is synchronously pushed, and the inner lining 300 can be pushed up at least the thickness distance of one inner lining 300 along the direction from the storage part to the guiding part 1032 on the replacement part 103. In this way, through the driving force provided by the lifting mechanism 106 and with the guiding effect of the guiding part 1032, the inner lining 300 can be replaced onto the helmet 200, thereby solving the problem of the hygiene of the helmet 200.

[0187] The replacement device 100 provided in the third embodiment of the present application can be used alone to independently implement the installation of the disposable liner 300 of the helmet 200, and the disposable liner 300 of the helmet 200 can be removed manually by the user, or by using the helmet 200 liner 300 removal device.

[0188] The replacement device 100 provided in the third embodiment of the present application can be flexibly configured when used alone without considering the flipping mechanism 105. For example, a variety of linear drive mechanisms such as a cylinder, a screw or a lead screw mechanism, a linear motor, etc. can be used to achieve pushing up the thickness distance of at least one liner 300 in the direction from the storage portion to the guide portion 1032.

[0189] The replacement device 100 provided in the third embodiment of the present application can also be used in combination with the replacement device 100 provided in the first embodiment. For example, the replacement part 103 is applied to the replacement mechanism 1030. During the relative movement between the helmet 200 and the replacement mechanism 1030, the liner 300 can contact the helmet 200 during the relative movement and be replaced on the helmet 200 by the force generated by the contact, with the help of the guiding function of the guide part 1032.

[0190] The replacement device 100 provided in the third embodiment of the present application can also be used in combination with the replacement device 100 provided in the second embodiment. The helmet 200 can be raised and lowered manually by the user or driven by the lifting mechanism 102. The lining 300 is lifted by the lifting mechanism 106 by at least a thickness of the lining 300 to reach a position where it can contact the helmet 200. In the process of relative movement between the helmet 200 and the replacement mechanism 1030, the lining 300 can contact the helmet 200 during the relative movement and be replaced on the helmet 200 through the force generated by the contact by the lifting mechanism 106.

[0191] In some embodiments, the replacement device 100 includes an adapter 1061, which is provided with a first guide rail 1061a, and the first guide rail 1061a extends in a direction from the storage portion to the guide portion 1032; the lifting mechanism 106 includes a rotating motor 1062 and a first lifting component 1063, and the lifting output component 1065 is supported on the housing of the rotating motor 1062; the first lifting component 1063 is transmission-connected to the driving end of the rotating motor 1062, and the first output end of the first lifting component 1063 is movably connected to the first guide rail 1061a, and the first lifting component 1063 is configured to be able to move along the first guide rail 1061a under the drive of the rotating motor 1062, thereby converting the rotation vector of the rotating motor 1062 into a straight line vector along which the lifting mechanism 106 can move.

[0192] By supporting the lifting output member 1065 on the housing of the rotating motor 1062 and converting the rotational vector of the rotating motor 1062 into a linear vector, the rotating motor 1062 itself can be driven to move linearly, which can make the lifting mechanism 106 more integrated. The overall configuration of the lifting mechanism 106 can be arranged below the inner liner 300 to improve the integration of the entire replacement device 100. Moreover, by combining the replacement device 100 provided in this embodiment with the replacement device 100 provided in the above second embodiment, the lifting mechanism 106 can be cleverly arranged in the space between multiple replacement members 103, further improving the integration degree.

[0193] In some embodiments, the replacement member 103 is provided with a second guide rail 1033, and the first guide rail 1061a and the second guide rail 1033 are arranged in parallel. The lifting mechanism 106 further includes a second lifting assembly 1064. The second lifting assembly 1064 is drivingly connected to the first lifting assembly 1063. The second output end of the second lifting assembly 1064 is movably connected to the second guide rail 1033. The second lifting assembly 1064 is configured to be able to move along the second guide rail 1033 under the drive of the first lifting assembly 1063.

[0194] Through the movement of the second lifting assembly 1064 along the second guide rail 1033, while the lifting mechanism 106 pushes the inner liner 300 to move, the influence of the lifting mechanism 106 on the height position of the replacement member 103 can be avoided. And, in some embodiments, the inner liner 300 and the lifting output member 1065 are movably sleeved on the replacement member 103, and the guiding portion 1032 of the replacement member 103 can be used to provide guidance. The cooperation between the second lifting assembly 1064 and the second guide rail 1033 can further strengthen and improve the guiding effect while ensuring that the height position of the replacement member 103 remains unchanged and stably moving along the second guide rail 1033.

[0195] In some embodiments, the replacement device 100 includes a pair of adapter members 1061 arranged opposite to each other along the radial direction of the inner liner 300 and at least a pair of replacement members 103 arranged at intervals. A pair of first guide rails 1061a are provided on the opposite sides of the pair of adapter members 1061. The lifting mechanism 106 is arranged between the pair of adapter members 1061. The first lifting assembly 1063 has two first output ends, and the two first output ends are movably connected to the pair of first guide rails 1061a one by one; moreover, the second lifting assembly 1064 has two second output ends, and the two second output ends are movably connected to the pair of second guide rails 1033 one by one. Among them, the interval direction of the pair of replacement members 103 is perpendicular to the relative direction of the pair of adapter members 1061.

[0196] Furthermore, the replacement device 100 includes two pairs of replacement parts 103 arranged at intervals, and the two pairs of replacement parts 103 are located between a pair of adapter parts 1061. That is to say, the interval direction of the two pairs of replacement parts 103 is the same as the relative direction of the pair of adapter parts 1061, while the interval direction of the two replacement parts 103 in each pair of replacement parts 103 is perpendicular to the relative direction of the pair of adapter parts 1061.

[0197] The lifting mechanism 106 includes two second lifting components 1064, and the two second lifting components 1064 are arranged in one-to-one correspondence with the two pairs of replacement parts 103. That is to say, the two second output ends in one second lifting component 1064 are arranged in one-to-one correspondence with the two replacement parts 103 in one pair of replacement parts 103, and the two second output ends in the other second lifting component 1064 are arranged in one-to-one correspondence with the two replacement parts 103 in the other pair of replacement parts 103.

[0198] Among them, the rotating motor 1062 is arranged between the two second lifting components 1064, the two second lifting components 1064 are arranged between a pair of adapter parts 1061, and the position where the rotating motor 1062 is located is approximately the central position in the horizontal plane, which can improve the balance of the replacement mechanism 1030.

[0203] In some embodiments, the inner liner 300 is provided with a plurality of detachable members 302 arranged along the same circumferential direction. A through hole 30222 penetrating its thickness is provided at the center of the detachable member 302, and the plurality of detachable members 302 are movably sleeved on the receiving portion one by one through the plurality of through holes 30222.

[0204] During the relative movement between the helmet 200 and the replacement mechanism 1030, the two distal end force application portions 30221 of the inner liner 300 apply force to the two distal end 2025 force receiving portions on the locking mechanism of the helmet 200, so that the locking mechanism is switched from the locked position to the unlocked position, and then enters the locking mechanism. Under the elastic force of the elastic member 2023, the locking mechanism is switched from the unlocked position to the locked position, and then the inner liner 300 is locked on the locking mechanism 202.

[0205] In some embodiments, the push output member 1065 includes a push shell 1065b and a push plate 1065c, wherein the push shell 1065b is disposed below the push plate 1065c, and the push shell 1065b and the push plate 1065c jointly define a push space, wherein the liner 300 is supported on the push plate 1065c, and the rotary motor 1062, the first push assembly 1063 and the second push assembly 1064 are all disposed in the push space.

[0206] Reference Figures 43 to 47 ,as well as Figures 52 to 54 As shown, the helmet lining replacement device 100 provided in the fourth embodiment of the present application includes a flipping mechanism 105, a replacement mechanism 1030 and a lifting mechanism 106. The flipping mechanism 105 has a driving axis, and the replacement mechanism 1030 is connected to the flipping mechanism 105 by transmission, and can be flipped around the driving axis under the drive of the flipping mechanism 105. The replacement mechanism 1030 includes a replacement part 103 and a replaceable liner 300, and the replacement part 103 has a disassembly part 1031 and a guide part 1032, and the disassembly part 1031 and the guide part 1032 are respectively arranged on both sides of the driving axis. The liner 300 is movably sleeved on the replacement part 103 and is restricted between the disassembly part 1031 and the guide part 1032; wherein, the disassembly part 1031 is used to disassemble the used liner 300 from the inner side of the wearing opening 2011 of the helmet 200, and the guide part 1032 is used to guide the unused liner 300 to the inner side of the wearing opening 2011. The pushing mechanism 106 is used to push the liner 300 along the direction from the disassembly portion 1031 to the installation guide portion 1032 by a distance equal to at least the thickness of the liner 300 .

[0207] Since the replacement mechanism 1030 can be flipped around its driving axis under the drive of the flipping mechanism 105, the angular positions of the disassembly portion 1031 and the guiding portion 1032 can be flexibly set or selected. For example, the angular positions of the disassembly portion 1031 and the guiding portion 1032 can be switched at the same angle by flipping the replacement mechanism 1030, so that the guiding and disassembly of the liner 300 of the helmet 200 can be completed at the same position. With the help of the pushing mechanism 106 and the guiding effect of the guiding portion 1032, the liner 300 can be pushed along the direction from the disassembly portion 1031 to the guiding portion 1032 by at least a thickness of the liner 300, and the liner 300 can be replaced on the helmet 200, thereby solving the problem of hygiene of the helmet 200.

[0208] In some embodiments, the liner 300 has a central axis, that is, the above-mentioned coaxial line, and the central axis is perpendicular to and intersects the drive axis. The replacement mechanism 1030 includes a plurality of replacement parts 103, and the plurality of replacement parts 103 are arranged at intervals along the same circumferential direction with the central axis as the center, that is, the plurality of replacement parts 103 are distributed in equal numbers on both sides of the drive axis; wherein the plurality of disassembly parts 1031 of the plurality of replacement parts 103 have the same orientation, the plurality of guide parts 1032 of the plurality of replacement parts 103 have the same orientation, and the same liner 300 is movably connected with the plurality of replacement parts 103 respectively.

[0209] In some embodiments, the lifting mechanism 106 is not associated with the flipping mechanism 105, and the lifting mechanism 106 can be arranged on the side wall of the housing 101. A plurality of stacked liners 300 can be supported on the lifting output member 1065, and the lifting output member 1065 can be movably sleeved on the replacement member 103, or the lifting output member 1065 can be slidably connected to other components in the replacement mechanism 1030 that can be flipped synchronously.

[0210] For example, the push mechanism 106 has a lifting part and a telescopic part, the telescopic part has a fixed shell and a telescopic end, the fixed shell is connected to the lifting part by transmission, and can push the liner 300 by at least a thickness of the liner 300 along the direction of the disassembly part 1031 pointing to the guide part 1032 under the control of the lifting part. The telescopic end can be telescopic relative to the fixed shell, and a plug-in structure, such as a plug-in hole, can be provided on the push output member 1065. When the replacement mechanism 1030 is already in the first angle position or the second angle position, the telescopic end can be plugged into the plug-in structure in the extended state, and then connected to the push output member 1065, so that the push output member 1065 is synchronously lifted and lowered with the fixed shell, thereby completing the pushing of a thickness of the liner 300. When the replacement mechanism 1030 is switched and flipped between the first angle position and the second angle position, the telescopic end is in a retracted state and does not interfere with the flipping of the replacement mechanism 1030.

[0211] In other embodiments, the pushing mechanism 106 is directly or indirectly connected to the flipping mechanism 105 and is configured to be able to be flipped synchronously with the replacement mechanism 1030 under the drive of the flipping mechanism 105 .

[0212] In a specific embodiment, the pushing mechanism 106 is directly connected to the flipping mechanism 105 by transmission. For example, the pushing mechanism 106 adopts a cylinder mechanism, the cylinder is vertically arranged, the fixed part of the cylinder mechanism is fixed relative to the replacement part 103, and the pushing output part 1065 is supported and connected to the telescopic part of the cylinder. The pushing output part 1065 is driven by the telescopic part, and the cylinder itself can be flipped synchronously with the replacement mechanism 1030.

[0213] In another specific embodiment, the lifting mechanism 106 is indirectly drivingly connected to the flipping mechanism 105.

[0214] The replacement mechanism 1030 includes an adapter 1061. The adapter 1061 is coaxial and drivingly connected to the flipping mechanism 105. The lifting mechanism 106 is movably connected to the adapter 1061 and the replacement part 103. The adapter 1061 is configured to be able to drive the replacement part 103 to flip synchronously through the lifting mechanism 106 under the drive of the flipping mechanism 105. The lifting mechanism 106 is configured to be able to move relative to both the replacement part 103 and the adapter 1061 along the direction from the disassembly part 1031 to the guiding part 1032, thereby pushing the lining 300 and allowing the position of the replacement part 103 relative to the driving axis to remain unchanged.

[0215] In some specific embodiments, the replacement device 100 includes a pair of adapters 1061 disposed opposite each other along the driving axis, as well as a first bracket 1081 and a second bracket 1082. Among them, the first bracket 1081 and the second bracket 1082 are spaced apart along the driving axis and are fixed relative to the housing 101. Among them, a pair of adapters 1061 are disposed between the first bracket 1081 and the second bracket 1082, and transfer structures 1061d are respectively provided on the pair of adapters 1061.

[0216] The flipping mechanism 105 includes a flipper 1051 and a flipping shaft 1052 coaxially connected to the flipper 1051. The flipper 1051 is disposed outside the first bracket 1081. The flipping shaft 1052 rotatably penetrates through the first bracket 1081. The end of the flipping shaft 1052 inside the first bracket 1081 is coaxial and drivingly connected to a transfer structure 1061d, and thus is drivingly connected to an adapter 1061, and can drive the adapter 1061 to rotate. Another transfer structure 1061d is rotatably disposed on the second bracket 1082, that is, the other adapter 1061 can rotate relative to the second bracket 1082.

[0217] Under the drive of the flipping mechanism 105, the adapter 1061 can rotate relative to the first bracket 1081 and the second bracket 1082 with the driving axis as the center. The lifting mechanism 106 is movably connected to the adapter 1061, and the lifting mechanism 106 is movably connected to the replacement part 103. Therefore, when the flipping mechanism 105 drives the adapter 1061 to rotate, the adapter 1061 synchronously drives the lifting mechanism 106 and the replacement part 103 to flip with the driving axis as the center. That is to say, the adapter 1061 is configured to be able to drive the replacement part 103 to flip synchronously through the lifting mechanism 106 under the drive of the flipping mechanism 105.

[0218] In addition, the pushing mechanism 106 is movably connected to the replacement part 103. The pushing mechanism 106 can transmit the flipping power to the replacement part 103 through the movable connection, so that the replacement part 103 flips synchronously, and the movable connection can also allow the pushing mechanism 106 to move relative to the replacement part 103, which not only realizes the function of the pushing mechanism 106 to push up the lining 300, but also realizes the function of keeping the position of the replacement part 103 relative to the drive axis unchanged. That is to say, the pushing mechanism 106 is configured to be able to move along the direction from the disassembly part 1031 to the guide part 1032, and at the same time relative to the replacement part 103 and the adapter 1061, thereby pushing the lining 300 and allowing the replacement part 103 to remain in position relative to the drive axis unchanged.

[0219] More specifically, the adapter 1061 is provided with a first guide rail 1061a, and the replacement part 103 is provided with a second guide rail 1033. The first guide rail 1061a and the second guide rail 1033 are arranged in parallel and perpendicular to the drive axis. The lifting mechanism 106 is movably connected to the adapter 1061 and the replacement part 103 through the first guide rail 1061a and the second guide rail 1033, respectively, and is configured to be able to move in the direction from the disassembly part 1031 to the installation guide part 1032 under the guidance of the first guide rail 1061a and the second guide rail 1033, thereby pushing the liner 300.

[0220] Among them, the first guide rail 1061a and the second guide rail 1033 can be rack guides, which can allow the transmission of flipping power, and can also allow the lifting mechanism 106 to be movably connected to the adapter 1061 and the replacement part 103 through the engagement of the gear and the rack guide. The rack guide can also prevent the replacement part 103 from detaching from the lifting mechanism 106.

[0221] In some embodiments, the lifting mechanism 106 includes a rotary motor 1062, a first lifting assembly 1063 and a lifting output member 1065, wherein the lifting output member 1065 is supported on the housing of the rotary motor 1062, and the liner 300 is supported on the lifting output member 1065. The first lifting assembly 1063 is transmission-connected to the driving end of the rotary motor 1062, and the first output end of the first lifting assembly 1063 is movably connected to the first guide rail 1061a. The first lifting assembly 1063 is configured to be able to move along the first guide rail 1061a under the drive of the rotary motor 1062, thereby converting the rotation vector of the rotary motor 1062 into a linear vector along which the lifting mechanism 106 can move.

[0222] In some embodiments, the pushing mechanism 106 also includes a second pushing component 1064, which is transmission-connected to the first pushing component 1063, and a second output end of the second pushing component 1064 is movably connected to the second guide rail 1033. The second pushing component 1064 is configured to be able to move along the second guide rail 1033 under the drive of the first pushing component 1063.

[0223] Among them, the first pushing assembly 1063 and the second pushing assembly 1064 provided in the fourth embodiment can be consistent with the first pushing assembly 1063 and the second pushing assembly 1064 in the replacement device 100 provided in the third embodiment, and will not be repeated here.

[0224] In some embodiments, the adapter 1061 and the replacement part 103 are arranged at intervals along the circumference of the liner 300, and the lifting mechanism 106 is arranged in the space enclosed by the adapter 1061 and the replacement part 103. The lifting mechanism 106 has a lifting output member 1065, which is located at the top of the lifting mechanism 106. The liner 300 is supported on the lifting output member 1065 and is stacked between the guide part 1032 and the lifting output member 1065. Furthermore, the liner 300 is provided with a through hole 30222, and the lifting output member 1065 is provided with a sliding hole. The through hole 30222 and the sliding hole are coaxially arranged, and the through hole 30222 and the sliding hole are both movably sleeved on the replacement part 103.

[0225] In some embodiments, the replacement part 103 is arranged beside the drive axis, and the replacement part 103 has a mid-vertical plane between the guide part 1032 and the disassembly part 1031, and the drive axis is located in the mid-vertical plane, which can ensure that the height of the replacement part 103 is consistent before and after flipping. One end of the first guide rail 1061a is adjacent to the guide part 1032, and the other end of the first guide rail 1061a is adjacent to the disassembly part 1031. The length of the first guide rail 1061a extending from the mid-vertical plane to the guide part 1032 is consistent with the length extending from the mid-vertical plane to the disassembly part 1031. The second guide rail 1033 and the first guide rail 1061a are set to be of equal length to ensure that the adapter 1061 and the replacement part 103 are located in the same horizontal plane at the same height, and to ensure that the lifting mechanism 106 can operate smoothly between the adapter 1061 and the replacement part 103.

[0226] Optionally, the lifting mechanism 102 is connected to the helmet 200 by transmission. The lifting mechanism 102 includes a lifting assembly 1021 and a driven part 1022, which is driven to extend along the circumference of the replacement port 1011. The lifting direction of the driven part 1022 is perpendicular to the circumference of the replacement port 1011. The driven part 1022 is connected to the lifting assembly 1021 by transmission, and is configured to be able to approach or move away from the replacement port 1011 along the lifting direction under the drive of the lifting assembly 1021. The detachable assembly 104 is arranged on the side of the driven part 1022 facing the replacement port 1011. The detachable assembly 104 is used to detachably install the 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.

[0227] In some embodiments, one circumferential end of the driven member 1022 is drivingly connected to the lifting assembly 1021, and the detachable assembly 104 is provided at the other circumferential end of the driven member 1022. In this way, the detachable assembly 104 and the lifting assembly 1021 are staggered in the circumferential direction, which is conducive to making full use of the circumferential space for layout, and can save space in the lifting direction and reduce the overall volume of the replacement device 100.

[0228] In some embodiments, the driven member 1022 is a cantilever beam member, and the other end of the driven member 1022 is suspended. The cantilever beam member can provide a good support basis for the detachable installation of the helmet 200, making the support received by the helmet 200 more stable and reliable. Moreover, by providing the lifting assembly 1021 only on one circumferential side of the driving member 1021a and leaving the other side suspended, the driven member 1022 can have a slight floating in the lifting direction, which can avoid damaging the lifting assembly 1021 due to overly rigid contact when the locking mechanism 202 on the helmet 200 is inserted into the replacement part 103.

[0229] In some embodiments, the lifting assembly 1021 includes a driving member 1021a and a transmission lead screw 1021b, and 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 drivingly inserted into the transmission hole 1022a 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.

[0230] Through the arrangement of the transmission lead screw 1021b, and by providing the driven member 1022 with the transmission hole 1022a and drivingly inserting the transmission lead screw 1021b into the transmission hole 1022a, 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 assembly 104 and the helmet 200 can be improved.

[0231] In some embodiments, the lifting assembly 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, the optical hole 1022b penetrates the driven member 1022 in the lifting direction, and the optical hole 1022b is sleeved on the optical axis 1021c and can move along the optical axis 1021c.

[0232] By providing the optical axis 1021c and providing the driven member 1022 with an optical hole 1022b, the optical axis 1021c is inserted into the optical hole 1022b in a driving manner. The optical axis 1021c can not only provide a guiding function for the driven member 1022 to move up and down, but also enable the driven member 1022 to move up and down stably. Therefore, the lifting stability of the detachable assembly 104 and the helmet 200 can be further improved.

[0233] In some embodiments, the optical axis 1021c and the detachable assembly 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 assembly 104 can be circumferentially arranged on both sides of the optical axis 1021c.

[0234] In some embodiments, the replacement device 100 includes two lifting mechanisms 102 and two detachable assemblies 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 assemblies 104 are arranged opposite to each other in the radial direction of the housing 101, and the two detachable assemblies 104 are respectively arranged on the two driven members 1022 one by one. Among them, the structures of the two driven members 1022 may be the same or different, and the structures of the two detachable assemblies 104 may be the same or different.

[0235] By providing the two detachable assemblies 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.

[0236] In some embodiments, the detachable assembly 104 includes a movable assembly 1041 and a buffer member 1042. The movable assembly 1041 is used for detachably installing the helmet 200. The buffer member 1042 extends along the lifting direction. One end of the buffer member 1042 is connected to the movable assembly 1041, and the other end of the buffer member 1042 is directly or indirectly connected to the driven member 1022. The buffer member 1042 is configured to provide buffering when the helmet 200 is driven by an external force in the lifting direction pointing to the replacement opening 1011 to drive the movable assembly 1041 to move relative to the driven member 1022.

[0237] Among them, the buffer member 1042 can be any elastic member, for example, it can be a linear spring. One end of the buffer member 1042 is connected to the movable assembly 1041, and the movable assembly 1041 can be detachably installed with the helmet 200. The other end of the buffer member 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 member 103 being inserted into each other, the reaction force of the replacement member 103 on the helmet 200 can be buffered by the buffer member 1042, and the helmet 200 can be allowed to move slightly backward in the opposite direction of insertion. In this way, it can avoid the adverse impact on the lifting mechanism 102 caused by the reaction force generated when the locking mechanism 202 of the helmet 200 and the replacement member 103 are inserted into each other, and the buffer member 1042 can absorb this part of the acting force.

[0238] In some embodiments, the detachable assembly 104 includes two buffer members 1042, and the two buffer members 1042 are arranged on both sides of the movable assembly 1041 along the circumferential direction. By the two buffer members 1042 arranged along the circumferential direction, the buffering effect can be more effectively and balancedly achieved.

[0239] In some embodiments, the detachable assembly 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 along the lifting direction. The movable assembly 1041 has a connecting end, and the connecting end is located between the limiting end 1043b and the driven member 1022 along the lifting direction. 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 port 1011 along the lifting direction and to press the connecting end against the driven member 1022 when the external force is withdrawn.

[0240] 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 assembly 1021 is fixed. 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. Thus, when the helmet 200 is slightly moved backward due to 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 then the buffer member 1042 is compressed to absorb the reaction force.

[0241] In some embodiments, at least two detachable components 104 are provided near the replacement opening 1011. The two detachable components 104 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.

[0242] Referring Figures 37 to 42 As shown, the two detachable components 104 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.

[0243] 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.

[0244] By the first detachable component 104a and the second detachable component 104b arranged along the radial direction, the front end side and the rear end side of the helmet 200 can be respectively detachably installed on the replacement device 100, ensuring the stability and balance of the helmet 200 during the lifting process.

[0245] 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 elastic force of the first elastic member 10413.

[0246] In this embodiment, by means of the rigid abutting force against the first detachable component 104a, the following second detachable structure 2012b can overcome the first elastic force of the first elastic member 10413 and be snap-fitted to the second detachable component 104b, and remain snap-fitted to the second detachable component 104b under the elastic force of the first elastic member 10413. Thus, it helps the user to perform labor-saving operations when detachably installing the helmet 200, and the user can conveniently install the helmet 200 between the first detachable component 104a and the second detachable component 104b. Wherein, the first detachable structure 2012a and the second detachable structure 2012b are oppositely arranged along the front-back direction of the helmet 200.

[0247] 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.

[0248] 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 that when the helmet 200 is installed towards the second detachable component 104b, it acts on the second elastic member 10415 and stores elastic force. Correspondingly, when removing the helmet 200, the second elastic member 10415 can assist the helmet 200 to bounce upwards and disengage from the second detachable component 104b through the stored elastic force.

[0249] 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. One end of the first elastic member 10413 is connected to the first sliding member 10412, and the other end is fixed relative to the main body member 10411; the first sliding member 10412 is slidably arranged on the main body member 10411 and can slide along the radial direction, and the first sliding member 10412 is used for detachably snap-fitting with the second detachable structure 2012b of the helmet 200.

[0250] Among them, the detachable component 104 has the above two fixing members 1043, the main body member 10411 has the above two connection ends, the two connection ends are respectively arranged on both circumferential sides of the main body member 10411, the two fixing members 1043 are also respectively arranged on both circumferential sides of the main body member 10411, and the two buffer members 1042 are respectively arranged between the two limiting ends 1043b and the two connection ends. 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.

[0251] Among them, two first elastic members 10413 can be provided. The first sliding member 10412 is provided with two setting holes 10412a extending radially. The two first elastic members 10413 are respectively arranged in the two setting holes 10412a. The side of the first elastic member 10413 away from the first sliding member 10412 can be closed and fixed by a side plate 10411a, and the side plate 10411a belongs to a part of the main body member 10411.

[0252] 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.

[0253] Correspondingly, the side surface of the first sliding member 10412 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 detachably clamping to the second detachable structure 2012b.

[0254] Thus, during the installation of the helmet 200, the second detachable structure 2012b of the helmet 200 is aligned with the main body 10411 of the second detachable component 104b and the helmet 200 is pressed down, and the sliding guide surface c is used to provide a guiding 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 provided on the main body 10411, and the protrusion e can be connected to the slot structure. A position detection device 10416 can be provided on the main body 10411 to detect whether the helmet is installed in place.

[0255] The first elastic member 10413 and the first sliding member 10412 may be sequentially arranged in a radially inward or radially outward direction. In some embodiments, the first elastic member 10413 is radially arranged outside the first sliding member 10412, one end of the first elastic member 10413 facing inward is connected to the first sliding member 10412, and the other end of the first elastic member 10413 facing outward is fixed relative to the main member 10411.

[0256] 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 to the inside of the housing 101, the first elastic member 10413 and the second elastic member 10415 are arranged in sequence, and the first sliding member 10412 and the second sliding member 10414 are arranged in sequence; one end of the second elastic member 10415 is connected to the second sliding member 10414, and the other end is fixed relative to the main body 10411; the second sliding member 10414 is slidably arranged on the main body 10411, and the sliding path of the second sliding member 10414 and the extension direction of the second elastic member 10415 are both at an angle to the radial direction.

[0257] 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.

[0258] When the helmet 200 is installed toward the second detachable component 104b, it acts on the two second elastic members 10415 and makes them store elastic force. Correspondingly, when the helmet 200 is removed, the second elastic members 10415 can assist the helmet 200 to bounce upward and detach from the second detachable component 104b through the stored elastic force.

[0259] like Figures 18 to 20As shown, the helmet 200 includes a helmet shell 201, at least two locking mechanisms 202, and at least two detachable structures 2012. The locking mechanisms 202 are provided on the inner wall of the helmet shell 201. The two locking mechanisms 202 are arranged in pairs along the meridian direction of the helmet shell 201 or are spaced apart along the circumferential direction of the helmet shell 201. The locking mechanisms 202 are used for detachably connecting the replaceable inner lining 300. The detachable structures 2012 are provided on the outer wall of the helmet shell 201. The two detachable structures 2012 are arranged in pairs along the meridian direction of the helmet shell 201 or are spaced apart 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.

[0260] Since the locking mechanisms 202 are provided on the inner wall of the helmet shell 201, the two locking mechanisms 202 are arranged in pairs along the meridian direction of the helmet shell 201 or are spaced apart along the circumferential direction of the helmet shell 201, and the locking mechanisms 202 are used for detachably connecting the replaceable inner lining 300. Thus, the inner lining 300 of the helmet 200 can be replaced, and the hygienic safety of the shared helmet 200 can be ensured.

[0261] Furthermore, the detachable structures 2012 are provided on the outer wall of the helmet shell 201. The two detachable structures 2012 are arranged in pairs along the meridian direction of the helmet shell 201 or are spaced apart 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.

[0262] 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.

[0263] 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 user's wearing comfort.

[0264] 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.

[0265] In some specific embodiments, the helmet shell 201 has a wearing opening 2011 and a vertex f that are oppositely arranged along its central axis; the second detachable structure 2012b includes a sliding guide surface c and a clamping groove d. Along the direction from the wearing opening 2011 to the vertex f, the sliding guide surface c and the clamping groove d are arranged in sequence and 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.

[0266] Correspondingly, the structures of the above-mentioned first detachable component 104a and second detachable component 104b are set differently, so that when the first elastic member 10413 is configured such that the helmet 200 is clamped to the first detachable component 104a through the following first detachable structure 2012a, the following second detachable structure 2012b can overcome the first elastic force of the first elastic member 10413 and be clamped to the second detachable component 104b by means of the rigid abutting force with the first detachable component 104a, and remain clamped to the second detachable component 104b under the elastic force of the first elastic member 10413. In this way, it helps the user to perform labor-saving operations when detachably installing the helmet 200, and the user can conveniently install the helmet 200 between the first detachable component 104a and the second detachable component 104b. Among them, the first detachable structure 2012a and the second detachable structure 2012b are arranged oppositely along the front-rear direction of the helmet 200.

[0267] 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.

[0268] 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.

[0269] In some embodiments, the helmet shell 201 has a central axis passing through the vertex f of the helmet shell 201; along the direction of the central axis, the locking mechanism 202, the detachable structure 2012, and the vertex 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 arrange the lifting mechanism 102.

[0270] 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 in 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.

[0271] 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 the first direction, and both the first proximal slideway 2031a and the first distal slideway 2031a extend in 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.

[0272] 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 the first direction, and both the second proximal slideway 2032a and the second distal slideway 2032b extend in 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.

[0273] As a preferred embodiment of the locking mechanism 202 of the present application, the locking mechanism 202 may further include a locking housing 204. The locking housing 204 may be fixedly connected to the inner wall of the helmet shell 201 of the helmet 200. The upper end of the cage 203 is connected to the locking housing 204. The above-mentioned first slideway 2031 and the second slide 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.

[0274] As Figures 1 to 17 , such as Figure 29 and Figure 30 As shown in

[0275] In some embodiments, a plurality of locking mechanisms 202 are sequentially arranged along the circumference 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.

[0276] 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 circumference of the inner lining 300 body. Each detachable part 302 is provided with a fixed connection part 3021 and a detachable connection part 3022. Each detachable part 302 is fixedly connected to the inner lining 300 body through the fixed connection part 3021. 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.

[0277] When a plurality of the above-mentioned locking mechanisms 202 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 arranged in one-to-one correspondence with the plurality of locking mechanisms 202. The plurality of disassembly parts 1031 of the plurality of replacement parts 103 can detach the plurality of detachable parts 302 from the plurality of locking mechanisms 202 one by one. After the plurality of detachable parts 302 are detached, the inner lining 300 where the plurality of detachable parts 302 are located is detached.

[0278] 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 the first direction. The proximal end 2024 of any one of the locking members is disposed between the proximal end 2024 and the distal end 2025 of the other locking member in the first direction. 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 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.

[0279] 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 to move away from each other in the first direction, so that the locking mechanism 202 is switched from the locked position to the unlocked position. The first direction is perpendicular to the lifting direction.

[0280] 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 part 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.

[0281] 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 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 is switched from the unlocked position to the locked position and the first locking member 2021 is synchronously switched from the unlocked position to the locked position.

[0282] In some embodiments, two proximal ends 2024 are provided with a pair of proximal force-receiving sides 2024a facing each other. 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 parts 1031a are respectively provided on both sides of the disassembly part 1031 along the first direction. The two proximal force-applying parts 1031a are symmetrically arranged along the first direction, and the two proximal force-applying parts 1031a are used to abut against the pair of proximal force-receiving sides 2024a.

[0283] 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 to move away from each other along the first direction. By acting on the pair of proximal force-receiving sides 2024a of the two proximal ends 2024 through the pair of proximal force-receiving sides 2024a of the pair of proximal force-applying parts 1031a, the two proximal ends 2024 are forced to move away from each other, so that the two distal ends 2025 of the two locking parts approach each other, and the two locking parts are simultaneously switched from the locking position to the unlocking position, and the replaceable inner lining 300 is unlocked and can be detached from the locking mechanism 202.

[0284] In some embodiments, a through hole 30222 is provided at the center of the above-mentioned detachable connection part 3022. The through hole 30222 can be arranged opposite to the through space 2026 between the two proximal ends 2024 of the above-mentioned locking mechanism 202. The hole edge of the through hole 30222 includes two first expansion parts 30222a and two second expansion parts 30222b arranged oppositely. 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, and the first expansion part 30222a and the second expansion part 30222b are alternately arranged along the circumferential direction of the through hole 30222; wherein, both the through hole 30222 and the through space 2026 are used for passing through the disassembly part 1031 of the replacement part 103.

[0285] Wherein, the maximum distance between the two first expansion 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 expansion parts 30222a, contact the two proximal force-receiving sides 2024a of the two proximal ends 2024 on the two locking parts and apply the above-mentioned second external force, and allow the two proximal force-applying parts 1031a to smoothly exit the through hole 30222 and the through space 2026.

[0286] Further, a stripping portion 1031c is provided on the disassembly portion 1031 along a direction perpendicular to the first direction. The stripping portion 1031c is provided with an inclined surface. In other words, the stripping portion 1031c and the proximal end biasing portion 1031a are arranged at intervals along the circumferential direction of the disassembly portion 1031. The stripping portion 1031c includes a main body portion a and a telescopic portion b. The main body portion a is connected to the disassembly portion 1031 through the telescopic portion b, so that the stripping portion 1031c can telescopically move relative to the disassembly portion 1031 along a direction perpendicular to the first direction.

[0287] Further, the distance from the edge of the second expansion portion 30222b to the central axis of the through hole 30222 is less than the maximum distance from the stripping portion 1031c to the central axis of the disassembly portion 1031 when the stripping portion 1031c is in the extended state, and greater than the maximum distance from the stripping portion 1031c to the central axis of the disassembly portion 1031 when the stripping portion 1031c is in the contracted state. The natural state of the second expansion portion 30222b is the extended state. Due to the arrangement of the inclined surface, the second expansion portion 30222b can prevent the extended stripping portion 1031c from passing through the through hole 30222 when the replacement part 103 exits the through hole 30222, and can squeeze the stripping portion 1031c into the contracted state and allow the stripping portion 1031c to pass through the through hole 30222 when the replacement part 103 enters the through hole 30222.

[0288] Specifically, during the process of the disassembly portion 1031 entering the through hole 30222 and the through space 2026, the stripping portion 1031c is squeezed by the second expansion portion 30222b and switches from the extended state to the contracted state. After the stripping 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 stripping portion 1031c disappears, and the stripping portion 1031c naturally switches to the extended state. Synchronously, the two proximal end biasing portions 1031a apply a second external force to the two proximal ends 2024 and drive the two distal ends 2025 of the first locking member 2021 and the second locking member 2022 to approach each other, and the replaceable inner liner 300 is disassembled. During the process of the disassembly portion 1031 exiting the through space 2026 and the through hole 30222, the stripping portion 1031c strips the replaceable inner liner 300.

[0289] As Figures 1 to 17 and as Figure 27 and Figure 28 shown, 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 be in the unlocking position by overcoming the elastic force of the elastic member 2023 under the action of an external force, and can be in the locking position under the elastic force of the elastic member 2023.

[0290] The replacement device 100 includes a replacement part 103. The replacement part 103 has an interconnected guiding part 1032 and a receiving part. The replaceable inner lining 300 is provided with a detachable part 302 and is sleeved on the receiving part through the detachable part 302. When the helmet 200 is installed on the replacement device 100, the guiding 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 lift 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, so that the locking mechanism 202 is switched from the locking position to the unlocking position, and the detachable part 302 is locked under the elastic force of the elastic part 2023.

[0291] The lifting mechanism 102 can drive one of the helmet 200 and the replacement part 103 to lift 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, so that the locking mechanism 202 is switched from the locking position to the unlocking position, and the detachable part 302 is locked under the elastic force of the elastic part 2023, thereby 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 alternatively drives the helmet 200 or the replacement part 103, and conveniently installs the disposable inner lining 300 on the helmet 200.

[0292] 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 manner. 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.

[0293] 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 part 302 are used for detachably connecting to the helmet shell 201 of the helmet 200.

[0294] When a plurality of the locking mechanisms 202 provided in the above embodiments are provided on the inner wall of the helmet shell 201 of the helmet 200, the plurality of detachable connecting portions 3022 of the plurality of detachable members 302 are in one-to-one pressing butt joint with the plurality of locking mechanisms 202, and the plurality of guiding portions 1032 of the plurality of replacement members 103 can be inserted into the plurality of locking mechanisms 202 one by one, and the inner lining 300 where the plurality of detachable members 302 are located is installed on the locking mechanisms 202.

[0295] 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 detachable inner lining 300.

[0296] 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 a position away from each other; when the locking mechanism 202 is in the unlocked position, the two distal ends 2025 are in a position close to each other.

[0297] The lifting mechanism 102 drives one of the helmet 200 and the replacement member 103 to lift relative to the other. The guiding portion 1032 enters between the two proximal ends 2024, and the inner lining 300 and the locking mechanism 202 are pressed and butted in the lifting direction, so as to force the detachable member 302 to act on the locking mechanism 202 and overcome the elastic force of the elastic member 2023, and drive the two proximal ends 2024 to be clamped with each other in the first direction, that is, the distal ends 2025 of the first locking member 2021 and the 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 installed on the locking mechanism 202 and is locked under the elastic force of the elastic member 2023.

[0298] Since there are two elastic members 2023 in this embodiment, during the process that the second locking member 2022 switches from the locking position to the unlocking position along the first direction and the first locking member 2021 switches from the locking position to the unlocking position along the first direction, the proximal end 2024 of the second locking member 2022 and the distal end 2025 of the first locking member 2021 approach each other and simultaneously drive the elastic member 2023 connected therebetween to store elastic force. The elastic member 2023 stores elastic force in a compressed manner. 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 in a compressed manner. Under the action of the elastic forces of the two elastic members 2023, the second locking member 2022 switches from the unlocking position to the locking position and the first locking member 2021 synchronously switches from the unlocking position to the locking position.

[0299] In some embodiments, the two distal ends 2025 are provided with a pair of force-receiving sides 2025 of the distal ends 2025 that face away from each other. The force-receiving sides 2025 of the distal ends 2025 are inclined relative to the first direction, and the pair of force-receiving sides 2025 of the distal ends 2025 are 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 that face 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 2025 of the two distal ends 2025 and overcome the elastic force of the elastic member 2023.

[0300] During the process that the replaceable inner lining 300 is automatically installed on the locking mechanism 202, a plurality of detachable members 302 are aligned with a plurality of locking mechanisms 202 one by one. A pair of distal-end force-applying portions 30221 of the detachable connecting portion 3022 in the detachable member 302 apply force to the pair of force-receiving sides 2025 of the two distal ends 2025 through the pair of distal-end force-applying sides 30221a. Since both the distal-end force-applying sides 30221a and the force-receiving sides 2025 of the distal ends 2025 are inclined, the two distal ends 2025 of the two locking members can be forced to approach each other and switch from the locking position to the unlocking position.

[0301] Furthermore, the two distal-end force-applying portions 30221 are provided with a pair of second engaging structures 2025b that face each other. The force-receiving sides 2025 of the distal ends 2025 and the second engaging structures 2025b on the same distal-end force-applying portion 30221 are arranged in sequence along the lifting direction and are smoothly connected. The two second engaging structures 2025b are engaged with the pair of second engaging structures 2025b under the action of the elastic force of the elastic member 2023.

[0302] Since the distal force - applying side 30221a and the first latching structure 30221b are smoothly connected, and the distal force - receiving side 2025 and the second latching structure 2025b are smoothly connected. As the movement continues, a pair of distal force - receiving sides 2025 disengage from a pair of distal force - applying sides 30221a. Under the elastic force of the two elastic members 2023, the two locking members move away from each other respectively, and then the first latching structure 30221b and the second latching structure 2025b are successfully latched.

[0303] Among them, one of the first latching structure 30221b and the second latching structure 2025b can be a groove structure, and the other can be a protrusion structure. Exemplarily, in some specific embodiments, the first latching structure 30221b can be a groove structure, specifically a notch structure penetrating the thickness of the detachable member 302. The second latching structure 2025b can be a protrusion structure, and its contour can just be latched into the notch structure.

[0304] In some embodiments, the guiding part 1032 is provided with an anti - detachment part 1032a on at least one side 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 guiding 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 guiding part 1032 when 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.

[0305] Based on the design of the extension part of the above - mentioned replaceable inner lining 300, 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 guiding part 1032 when the anti - detachment part 1032a is in the extended state, and greater than the maximum distance from the anti - detachment part 1032a to the central axis of the guiding 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 and allow the anti - detachment part 1032a to pass through the through - hole 30222 when the replacement part 103 enters the through - hole 30222.

[0306] 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 portion 1032a. After the anti - detachment portion 1032a enters the through - hole 30222, the inclined surface of the anti - detachment portion 1032a just contacts the inclined surface on the cage 203 and continues to maintain the contracted state. After the inner lining 300 is assembled, when the anti - detachment portion 1032a exits the through - space 2026 and the through - hole 30222, the anti - detachment portion 1032a pops out and continues to prevent the unused replaceable inner lining 300 from detaching from the storage portion.
