[0055] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0056] Before introducing a protective component, a car seat and a vehicle provided by the present application, the related technologies of the present application are first described.

[0057] In the related art, the car mainly uses two protective components, seat belts and safety seats, to restrain the upper body of the occupants, but lacks consideration for the protection of the occupants' legs. During the driving process of the car, if the vehicle stops suddenly or collides, the occupants' legs will continue to rush forward due to inertia due to the lack of leg protection. In this way, for the occupants sitting in the car seat, the difference in forward movement between the upper body and the legs will cause the seat belt to tighten the chest, which may easily cause chest injuries. For the occupants sitting in the safety seat, the lack of leg protection will cause the legs to bend too much, which may easily lead to the risk of injuries such as femoral fractures.

[0058] Based on this, the embodiments of the present application provide a protective component, a car seat and a vehicle, which are described in detail respectively through the following contents.

[0059] See also Figures 1 to 3 , Figure 1 is a schematic structural diagram of a protection assembly 1 provided in an exemplary embodiment of the present disclosure, Figure 2 is a side view of a protection assembly 1 provided in an exemplary embodiment of the present disclosure, Figure 3 1 is a schematic diagram of a structure in which a blocking member 11 provided in an exemplary embodiment of the present disclosure is located in a first position. An embodiment of the present application provides a protection assembly 1. The protection assembly 1 is used for a vehicle 3; the protection assembly 1 includes a blocking member 11 and an adjusting member 12. One end of the adjusting member 12 is connected to the blocking member 11, and the other end is fixedly connected to the vehicle 3. The adjusting member 12 is used to adjust the position of the blocking member 11 so that the blocking member 11 switches between at least the first position and the second position.

[0060] The blocking member 11 is configured to protect the legs of the occupant. The first position is the position where the blocking member 11 protects the legs of the occupant. The second position is the position where the blocking member 11 does not hinder the occupant from sitting.

[0061] It can be understood that the adjustment member 12 can be fixed to the car seat 2 of the vehicle 3, or to the roof of the vehicle 3, or to the door of the vehicle 3. The specific fixing position of the adjustment member 12 can be set according to the actual use scenario, as long as it does not hinder the passengers from sitting, and this embodiment does not limit this.

[0062] It will be appreciated that the stopper 11 may be located above the legs of an adjacent occupant.

[0063] Specifically, when in use, the adjustment member 12 can be located at the rear side of the occupant, and by adjusting the adjustment member 12, the stopper 11 can be moved above the legs of the occupant, such as Figure 4 As shown, Figure 4 1 is a schematic diagram of a use of the protection assembly 1 provided in an exemplary embodiment of the present disclosure. When in use, the adjustment member 12 can also be located in front of the occupant, and the stopper 11 can be moved above the occupant's legs by adjusting the assembly, such as Figure 5 As shown, Figure 5 1 is another schematic diagram of the use of the protective assembly 1 provided in the exemplary embodiment of the present disclosure. Of course, the adjustment member 12 can be located on the left or right side of the occupant. The specific position of the adjustment member 12 relative to the occupant can be set according to the actual use scenario, as long as it does not hinder the occupant from riding, and this embodiment does not limit this.

[0064] Among them, according to the positional relationship between the second position and the first position of the baffle 11, the adjusting member 12 can make the baffle 11 reciprocate in a direction perpendicular to the ground to switch the position of the baffle 11, for example, a telescopic rod, a pneumatic rod, etc. The adjusting member 12 can make the baffle 11 reciprocate in a direction parallel to the ground to switch the position of the baffle 11. The adjusting member 12 can also make the baffle 11 rotate around a straight line to switch the position of the baffle 11. The adjustment method of the baffle 11 by the adjusting member 12 can be set according to the actual use scenario, so that the baffle 11 does not hinder the occupant from sitting in the second position and can be located above the occupant's legs in the first position. This embodiment does not limit this.

[0065] In this embodiment, through the above arrangement, the blocking member 11 can not only not affect the passengers when in the second position, but also protect the passengers' legs when in the first position, thereby increasing the passengers' riding safety. In this way, the safety of the vehicle 3 can be improved.

[0066] Especially for children in safety seats placed rearward, the protection assembly 1 provided in this embodiment can effectively prevent the legs of children from rushing up quickly due to the sudden stop of the vehicle 3, thereby avoiding the risk of femur fracture and the like of children in safety seats placed rearward. In this way, it can play a good role in protecting children in safety seats placed rearward, and increase the safety of children sitting rearward.

[0067] See also Figure 1 or Figure 2 or Figure 3 In some embodiments, the adjusting member 12 includes a first member 13 and a second member 14. The first member 13 is connected to the stopper 11. One end of the second member 14 is hinged to the first member 13, and the other end is fixedly connected to the vehicle 3. The first member 13 rotates around the hinged portion between the first member 13 and the second member 14 to switch the stopper 11 between at least the first position and the second position.

[0068] It can be understood that the hinge can be hinged or hinged with a pin 191.

[0069] Specifically, the first piece 13 is hinged to the second piece 14 through the pin 191 , wherein the rod end of the pin 191 passes through the first piece 13 and the second piece 14 and is threadedly connected to the nut 192 .

[0070] In this embodiment, through the above arrangement, on the one hand, the blocking member 11 can be switched between the second position and the first position, and the overall structure of the adjusting member 12 can be simple and easy to assemble, thereby improving manufacturing efficiency and maintenance convenience.

[0071] In some embodiments, the first piece 13 and the second piece 14 are both telescopic rods. The telescopic end of the second piece 14 can drive a portion of the first piece 13 to be inserted into the second piece 14. Among them, the first piece 13 and the second piece 14 are both telescopic rods, so that the adjustment member 12 can not only switch the blocking member 11 between the second position and the first position, but also adjust the specific position of the blocking member 11 in the second position to avoid it hindering the occupants from riding in the vehicle 3.

[0072] It can be understood that since the second piece 14 is fixed relative to the vehicle 3, in this embodiment, the telescopic end of the second piece 14 can drive the portion of the first piece 13 to be inserted into the second piece 14, thereby increasing the adjustable position of the first piece 13 relative to the second piece 14, thereby improving the storage capacity of the adjusting piece 12, thereby facilitating reducing the space it occupies.

[0073] For example, the second piece 14 is fixed in the backrest assembly of the automobile seat 2, that is, the second piece 14 is connected to the backrest frame of the automobile seat 2. When the adjusting member 12 is folded, in addition to shortening the first piece 13, the first piece 13 can also be inserted into the second piece 14 to increase the size of the first piece 13 inserted into the backrest assembly, thereby reducing the size of the protective assembly 1 outside the backrest assembly, so as to reduce the space it occupies.

[0074] At the same time, by setting the second piece 14 as a telescopic rod, when the stopper 11 is in the second position, the adjustment piece 12 can be retracted into a certain component of the vehicle 3, for example, the car seat 2. In this way, when the stopper 11 is used, the stopper 11 can be pulled until the hinged portion between the first piece 13 and the second piece 14 is pulled out of the car seat 2, so that when the stopper 11 is rotated, the end of the first piece 13 close to the second piece 14 will not interfere with other components of the vehicle 3 due to the rotation.

[0075] In addition, since the first piece 13 can be inserted into the second piece 14 , it can be understood that the radial dimension of the second piece 14 is greater than the radial dimension of the first piece 13 .

[0076] Among them, the telescopic rod includes but is not limited to a pneumatic telescopic rod, a hydraulic telescopic rod, a nested telescopic rod, and a spiral telescopic rod.

[0077] See also Figure 6 , Figure 6 1 is a schematic diagram of the structure of the first member 13 provided in an exemplary embodiment of the present disclosure. In some embodiments, the first member 13 includes a first rod 131, a first sleeve 132 and a first telescopic structure 133. One end of the first rod 131 is connected to the stopper 11. The first sleeve 132 is sleeved on the first rod 131 and hinged to the second member 14. A plurality of first positioning holes 1322 are provided on the first sleeve 132. Along the axial direction of the first rod 131, a plurality of first positioning holes 1322 are arranged at intervals. The first telescopic structure 133 is arranged in the first rod 131. The first telescopic structure 133 has a first positioning end 1331. The first positioning end 1331 is configured to elastically abut against the inner wall of the first sleeve 132 and to be located in the first positioning hole 1322 when moving to the first positioning hole 1322. And, the first positioning end 1331 is configured to withdraw from the first positioning hole 1322 and return to elastically abut against the inner wall of the first sleeve 132 when being compressed along the axial direction of the first rod 131.

[0078] It can be understood that the first rod 131 is pulled or pressed down with force relative to the first sleeve 132, so that the first rod 131 moves relative to the first sleeve 132. During the movement of the first rod 131, when the first positioning end 1331 is opposite to a first positioning hole 1322 along the radial direction of the first rod 131, it will be inserted into the first positioning hole 1322 due to the elasticity of the first telescopic structure 133. Continuing to apply pressure to the first positioning end 1331 along the axial direction of the first rod 131 can make the first positioning end 1331 retract into the inner hole of the first sleeve 132 until the first positioning end 1331 moves to a position opposite to the next first positioning hole 1322. In this way, by pulling the first rod 131 with force relative to the first sleeve 132, the first piece 13 can be lengthened, and by pressing the first rod 131 with force relative to the first sleeve 132, the first piece 13 can be shortened.

[0079] Specifically, the first positioning hole 1322 is a through hole, so that the user can directly observe the position of the first positioning end 1331 .

[0080] In this embodiment, through the above scheme, the structure of the first piece 13 can be simple, which is convenient for manufacturing and maintenance, and the first piece 13 can have a variety of adjustable lengths to meet the usage requirements of different environments, thereby improving the adaptability of the protective component 1.

[0081] See also Figure 7 , Figure 7 yes Figure 6 In some embodiments, the first telescopic structure 133 includes a first spring 1332 and a first ejector pin 1333. The first spring 1332 is disposed in the first rod 131. One end of the first spring 1332 is connected to the first ejector pin 1333. One end of the first ejector pin 1333 away from the first spring 1332 is a first positioning end 1331.

[0082] It can be understood that when the first positioning end 1331 is inserted into the first positioning hole 1322, the first rod 131 is pulled or pressed down relative to the first sleeve 132, so that the first positioning end 1331 is squeezed by the hole wall of the first positioning hole 1322 and the first positioning end 1331 is retracted into the inner hole of the first sleeve 132. At this time, the first spring 1332 is in a compressed state.

[0083] It can be understood that when the first positioning end 1331 is located in the inner hole of the first sleeve 132, as the first rod 131 moves relative to the first sleeve 132, the first positioning end 1331 can be opposite to a first positioning hole 1322. At this time, the deformation restoring force of the first spring 1332 pushes the first positioning end 1331 to insert into the first positioning hole 1322 to limit the movement of the first rod 131 relative to the first sleeve 132.

[0084] In this embodiment, through the above arrangement, the first telescopic structure 133 is simple, which is convenient for manufacturing and maintenance.

[0085] See also Figure 7In some embodiments, there are two first ejector pins 1333. The two first ejector pins 1333 are respectively located at the two ends of the first spring 1332. In this way, on the one hand, the symmetry of the structure of the first member 13 can be improved, thereby improving the stress state of the first member 13; on the other hand, the matching surface between the first telescopic structure 133 and the first sleeve 132 can be increased to improve the reliability of the first telescopic structure 133 limiting the position of the first rod 131. In particular, when the area of ​​the matching surface between the first positioning end 1331 and the first positioning hole 1322 is small, the matching surface between each first telescopic structure 133 and the first sleeve 132 can be increased by providing two first ejector pins 1333 for each first telescopic structure 133, so as to improve the reliability of the matching between the first telescopic structure 133 and the first sleeve 132, thereby improving the length stability of the first member 13, so as to facilitate the reliability of the stopper 11 being in the first position.

[0086] See also Figure 7 In some embodiments, the first telescopic structure 133 further includes a first spring sleeve 1334. The first spring sleeve 1334 is disposed in the first rod 131. The first spring 1332 is disposed in the first spring sleeve 1334. One end of the first ejector pin 1333 close to the first spring 1332 is located in the first spring sleeve 1334. In this way, the deformation of the first spring 1332 can be guided by the first spring sleeve 1334 to improve the reliability of its deformation, thereby facilitating the smoothness of the first positioning end 1331 being inserted into the first positioning hole 1322 and the smoothness of the first positioning end 1331 being withdrawn from the first positioning hole 1322.

[0087] See also Figure 7 In some embodiments, the first ejector pin 1333 is a sphere. In this way, when the first ejector pin 1333 contacts the hole wall of the first positioning hole 1322, it can adapt to various contact angles, thereby improving the matching between the first ejector pin 1333 and the hole wall of the first positioning hole 1322, so as to facilitate the smooth progress of related operations.

[0088] In some embodiments, there are multiple first telescopic structures 133 , and the multiple first telescopic structures 133 are arranged at intervals along the axial direction of the first rod 131 .

[0089] Optionally, there are two first telescopic structures 133 .

[0090] In this embodiment, by providing a plurality of first telescopic structures 133 , the matching surface between the first telescopic structure 133 and the first sleeve 132 can be increased, so as to improve the reliability of the first telescopic structure 133 in limiting the position of the first rod 131 .

[0091] See also Figure 8 , Figure 81 is a schematic diagram of the structure of the second member 14 provided in an exemplary embodiment of the present disclosure. In some embodiments, the second member 14 includes a second rod 141, a second sleeve 142 and a second telescopic structure 143. One end of the second rod 141 is hinged to the first member 13. The second sleeve 142 is sleeved on the second rod 141, and at least one second positioning hole 1421 is provided on the second sleeve 142. The second telescopic structure 143 is provided in the second rod 141. The second telescopic structure 143 has a second positioning end 1431. The second positioning end 1431 is configured to elastically abut against the inner wall of the second sleeve 142, and is limited to be located in the second positioning hole 1421 when moving to the second positioning hole 1421. And, the second positioning end 1431 is configured to withdraw from the second positioning hole 1421 when being compressed along the axial direction of the second rod 141, and return to elastically abut against the inner wall of the second sleeve 142. Wherein, the second sleeve 142 is configured to be fixed relative to the vehicle 3. The second rod 141 can drive a portion of the first member 13 to be inserted into the second sleeve 142 .

[0092] Specifically, the second rod 141 is hinged to the first sleeve 132 .

[0093] Specifically, the second positioning hole 1421 is a blind hole, which can improve the strength of the second sleeve 142 .

[0094] It can be understood that the second rod 141 is pulled or pressed down with force relative to the second sleeve 142, so that the second rod 141 moves relative to the second sleeve 142. During the movement of the second rod 141, when the second positioning end 1431 is opposite to the second positioning hole 1421 along the radial direction of the second rod 141, it will be inserted into the second positioning hole 1421 due to the elasticity of the second telescopic structure 143. And continuing to apply pressure to the second positioning end 1431 along the axial direction of the second rod 141 can make the second positioning end 1431 retract into the inner hole of the second sleeve 142. In this way, by pulling the second rod 141 with force relative to the second sleeve 142, the second piece 14 can be lengthened, and by pressing the second rod 141 with force relative to the second sleeve 142, the second piece 14 can be shortened.

[0095] In this embodiment, through the above scheme, the structure of the second piece 14 can be simple, which is convenient for manufacturing and maintenance, and the second piece 14 can have a variety of adjustable lengths to meet the usage requirements of different environments, thereby improving the adaptability of the protective component 1.

[0096] See also Fig. 9 , Fig. 9 yes Figure 8In some embodiments, the second telescopic structure 143 includes a second spring 1432 and a second ejector pin 1433. The second spring 1432 is disposed in the second rod 141. One end of the second spring 1432 is connected to the second ejector pin 1433. One end of the second ejector pin 1433 away from the second spring 1432 is a second positioning end 1431.

[0097] It can be understood that when the second positioning end 1431 is inserted into the second positioning hole 1421, the second rod 141 is pulled or pressed down relative to the second sleeve 142, so that the second positioning end 1431 is squeezed by the groove wall of the second positioning hole 1421 and retracts into the inner hole of the second sleeve 142. At this time, the second spring 1432 is in a compressed state.

[0098] It can be understood that when the second positioning end 1431 is located in the inner hole of the second sleeve 142, as the second rod 141 moves relative to the second sleeve 142, the second positioning end 1431 can be opposite to the second positioning hole 1421. At this time, the deformation restoring force of the second spring 1432 pushes the second positioning end 1431 to insert into the first positioning hole 1322 to limit the movement of the second rod 141 relative to the second sleeve 142.

[0099] In this embodiment, the above arrangement makes the second telescopic structure 143 simple, which is convenient for manufacturing and maintenance.

[0100] See also Fig. 9 In some embodiments, the second telescopic structure 143 further includes a second spring sleeve 1434, the second spring sleeve 1434 is disposed in the second rod 141, the second spring 1432 is disposed in the second spring sleeve 1434, and one end of the second ejector pin 1433 close to the second spring 1432 is located in the second spring sleeve 1434. In this way, the deformation of the second spring 1432 can be guided by the second spring sleeve 1434 to improve the reliability of its deformation, thereby facilitating the smoothness of the second positioning end 1431 being inserted into the second positioning hole 1421 and the smoothness of the second positioning end 1431 being withdrawn from the second positioning hole 1421.

[0101] In some embodiments, the second ejector pin 1433 is a sphere, so that when the second ejector pin 1433 contacts the groove wall of the second positioning hole 1421, it can adapt to various contact angles, thereby improving the matching between the second ejector pin 1433 and the hole wall of the first positioning hole 1322, so as to facilitate the smooth progress of related operations.

[0102] In some embodiments, the first member 13 is configured to be slidably disposed in the second sleeve 142 .

[0103] It can be understood that since the second sleeve 142 is fixed relative to the vehicle 3, in this embodiment, by setting the first rod 131 to be slidable in the second sleeve 142, the adjustable position of the first rod 131 relative to the second sleeve 142 can be increased, thereby improving the storage capacity of the adjusting member 12, thereby facilitating reducing the space it occupies.

[0104] For example, the second sleeve 142 is fixed in the backrest assembly of the automobile seat 2, that is, the second sleeve 142 is connected to the backrest frame of the automobile seat 2. When the adjusting member 12 is folded, in addition to shortening the first member 13, the first member 13 can also be inserted into the second sleeve 142 to increase the size of the first member 13 inserted into the backrest assembly, thereby reducing the size of the protective assembly 1 outside the backrest assembly, so as to reduce the space it occupies.

[0105] In addition, since the first piece 13 can be inserted into the second sleeve 142, it can be understood that the radial dimension of the second sleeve 142 is greater than the radial dimension of the first piece 13. Correspondingly, the ball diameter of the second ejector pin 1433 is greater than the ball diameter of the first ejector pin 1333. Optionally, the ball diameter of the second ejector pin 1433 is 1.5 to 2.5 times the ball diameter of the first ejector pin 1333.

[0106] See also Fig.10 , Fig.10 1 is a schematic diagram of the structure of the adjustment member 12 provided in an exemplary embodiment of the present disclosure. In some embodiments, the adjustment member 12 also includes a telescopic limiting structure 15. The telescopic limiting structure 15 has a limiting end 151. The first member 13 is connected to the telescopic limiting structure 15. The second member 14 is provided with a limiting groove 161. The limiting end 151 is configured to be inserted into the limiting groove 161 when the blocking member 11 is located at the first position. And, the limiting end 151 is configured to abut against the second member 14 when the blocking member 11 is located at a position other than the first position.

[0107] Specifically, the limiting groove 161 may be provided on the second rod 141 , and the telescopic limiting structure 15 is provided on the first sleeve 132 .

[0108] It can be understood that when the first member 13 is rotated from the second position to the first position, the limiting end 151 is rotated from the position abutting against the second member 14 to the position opposite to the limiting groove 161. When the limiting end 151 is opposite to the limiting groove 161, the deformation restoring force of the telescopic limiting structure 15 pushes the limiting end 151 to insert into the limiting groove 161 to limit the rotation of the blocking member 11, so that the blocking member 11 can be stably in the first position to improve the protection reliability of the protection assembly 1.

[0109] It is understood that when rotating from the first position to the second position, the limiting end 151 is pulled to make the limiting end 151 withdraw from the limiting groove 161, and then the first member 13 is rotated in the opposite direction to move the blocking member 11 to the second position. At this time, the limiting end 151 abuts against the second member 14.

[0110] See also Fig.11 , Fig.11 1 is a schematic diagram of the position of the telescopic limiting structure 15 provided in an exemplary embodiment of the present disclosure. In some embodiments, the telescopic limiting structure 15 includes a third spring 152 and a limiting block 153. The third spring 152 is connected to the first member 13. One end of the limiting block 153 is connected to the third spring 152, and the other end is a limiting end 151.

[0111] It is understandable that when the limiting end 151 abuts against the second member 14 , the third spring 152 is in a compressed state. Thus, when the limiting end 151 is opposite to the limiting groove 161 , the deformation restoring force of the third spring 152 can push the limiting block 153 to be inserted into the limiting groove 161 .

[0112] In this embodiment, through the above arrangement, the overall structure of the telescopic limiting structure 15 is simple and easy to manufacture and assemble.

[0113] See also Fig.10 or Fig.11 In some embodiments, the first member 13 is provided with a guide hole 1321. Part of the stopper 153 is provided in the guide hole 1321. The stopper 153 is configured to move along the longest diameter of the guide hole 1321 when the stopper 11 is located at the first position, so that the stopper end 151 is inserted into the stopper groove 161. In this way, the movement of the stopper 153 can be guided by the guide hole 1321, thereby improving the smoothness of the stopper end 151 being inserted into the stopper groove 161.

[0114] Specifically, the guide hole 1321 is a strip-shaped hole, and the direction of the longest diameter thereof is perpendicular to the axis of the hinge.

[0115] The guide hole 1321 is disposed on the first sleeve 132 .

[0116] In addition, a spring mounting hole 1323 is provided on the hole wall of the guide hole 1321 away from the second member 14 , and a portion of the third spring 152 is disposed in the spring mounting hole 1323 .

[0117] See also Fig.11In some embodiments, the guide hole 1321 is a through hole. The middle of the limit block 153 is disposed in the guide hole 1321. Both ends of the limit block 153 are located outside the guide hole 1321 and can abut against the second member 14. In this way, the contact parts of the limit block 153 and the second member 14 can be symmetrical, thereby improving the stress state of the limit block 153 and the second member 14, so as to enhance the structural reliability of the adjustment member 12.

[0118] See also Fig.10 In some embodiments, the adjusting member 12 further includes a connecting block 16. One end of the connecting block 16 is connected to the second member 14, and the other end is hinged to the first member 13. The limiting groove 161 is provided on the connecting block 16. The limiting end 151 abuts against the connecting block 16.

[0119] It can be understood that the second piece 14 is a telescopic rod and needs to be fixed relative to the vehicle 3, so the structure of the second piece 14 is relatively complex. Therefore, if the structure of the second piece 14 hinged to the first piece 13 and the limit groove 161 are set on the second piece 14, the structural complexity of the second piece 14 will increase, resulting in higher manufacturing difficulty.

[0120] Specifically, the connecting block 16 is connected to the second rod 141 .

[0121] Based on this, in this embodiment, a connecting block 16 is arranged between the first piece 13 and the second piece 14, so that the structure of the second piece 14 hinged to the first piece 13 and the limiting groove 161 can be arranged on the connecting block 16, thereby reducing the manufacturing difficulty of the second piece 14, which is conducive to improving the manufacturability of the adjusting piece 12.

[0122] See also Fig.10 In some embodiments, the connecting block 16 includes a main body 162 and two ear plates 163. One end of the main body 162 is connected to the second member 14, and the other end is connected to the two ear plates 163. One end of the first member 13 away from the stopper 11 is inserted between the two ear plates 163 and is hinged to the two ear plates 163. The limiting groove 161 is provided on the ear plate 163. The limiting end 151 abuts against the edge of the ear plate 163. In this way, the connection between the first member 13 and the second member 14 is reliable.

[0123] The end of the rod of the pin 191 passes through an ear plate 163 , the first piece 13 and another ear plate 163 and is threadedly connected to the nut 192 .

[0124] See also Figure 8 In some embodiments, a plug hole 1411 is provided on the second member 14. One end of the connection block 16 away from the first member 13 is plugged into the plug hole 1411. In this way, the area of ​​the mating surface between the connection block 16 and the second member 14 can be increased, thereby improving the reliability of the connection between the second member 14 and the connection block 16.

[0125] Specifically, a plug hole 1411 is provided on the second rod 141 .

[0126] In addition to the arrangement of the telescopic limiting structure 15 in the above-mentioned embodiment, in some other embodiments of the present application, the arrangement of the telescopic limiting structure 15 may also adopt the following scheme. Specifically, the adjusting member 12 further includes a telescopic limiting structure 15, and the telescopic limiting structure 15 has a limiting end 151. The second member 14 is connected to the telescopic limiting structure 15, and the first member 13 is provided with a limiting groove 161. The limiting end 151 is configured to be inserted into the limiting groove 161 when the blocking member 11 is located at the first position; and the limiting end 151 is configured to abut against the first member 13 when the blocking member 11 is located at a position other than the first position.

[0127] In this embodiment, the specific configuration of the telescopic limiting structure 15 is the same as the configuration of the telescopic limiting structure 15 described above, and the only difference is the configuration positions of the limiting groove 161 and the limiting end 151. Therefore, the specific configuration of the telescopic limiting structure 15 is not described in detail in this embodiment.

[0128] See also Figure 1 or Fig.10 In some embodiments, there are two adjusting members 12. The two adjusting members 12 are arranged in parallel. In this way, the structural strength of the adjusting member 12 can be improved, thereby improving the durability of the adjusting member 12.

[0129] See also Fig.10 In some embodiments, the protection assembly 1 further includes a first connecting rod 17. Both ends of the first connecting rod 17 are respectively connected to the two adjusting members 12. The first connecting rod 17 is disposed adjacent to the blocking member 11. In this way, the area of ​​the connection portion between the blocking member 11 and the adjusting member 12 can be increased, thereby improving the reliability of the position of the blocking member 11 on the adjusting member 12.

[0130] See also Figure 1 In some embodiments, the first connecting rod 17 is at least partially disposed inside the stopper 11. In this way, the stability of the stopper 11 being fixed to the adjusting member 12 can be enhanced.

[0131] See also Figure 1 or Fig.10 In some embodiments, the protection assembly 1 further includes a second connecting rod 18. Both ends of the second connecting rod 18 are respectively connected to the two adjusting members 12. The second connecting rod 18 is arranged away from the blocking member 11. In this way, the structural strength of the adjusting member 12 can be improved, thereby improving the durability of the adjusting member 12.

[0132] Specifically, one end of the second rod 141 away from the first rod 131 is located at one end of the second sleeve 142 away from the first rod 131. The second connecting rod 18 is connected to the end of the second rod 141 away from the first rod 131. In this way, the movement stroke of the second rod 141 can also be limited by the second connecting rod 18 to prevent the second rod 141 from coming out of the second sleeve 142.

[0133] In some embodiments, the stopper 11 is a soft-pack structure, so as to enhance the comfort of the passengers.

[0134] It can be understood that the soft package structure refers to a structural form formed by wrapping and covering with soft materials. It may include a frame, foam and a wrapping layer. The foam is arranged on the frame, and the wrapping layer wraps the foam and the frame.

In this way, the stopper 11 can be used for multiple purposes, thereby reducing the space inside the vehicle 3 occupied by the protective assembly 1.

[0138] See also Fig.12 In some embodiments, when the stopper 11 is located at the second position, the adjusting member 12 is at least partially located inside the backrest assembly 22.
