[0095] The drive assembly 52 has a reasonable structural design, which can realize the intelligent and automatic movement of the storage plate 4, thereby improving the convenience of use. It can also realize that one drive motor 523 drives two sliding assemblies 3 to move at the same time, which can save space and reduce weight, and is also conducive to reducing costs.

[0096] In some embodiments of the present invention, Figure 1-Figure 5 As shown, the guide rail 2 includes: a track body 21, a first channel 22 and a second channel 23. The first channel 22 is arranged in the track body 21 and extends along the length direction of the track body 21. The second channel 23 is arranged in the track body 21 and extends along the length direction of the track body 21. A notch 221 is arranged on one side of the first channel 22 close to the second channel 23. The notch 221 extends along the length direction of the track body 21. The transmission member 51 passes through the second channel 23 in the track body 21, and both ends are located in the first channel 22 of the track body 21 and connected to the sliding assembly 3. In this way, the transmission members 51 can form their own motion loops without interfering with each other, and the two transmission members 51 can move in the same or opposite directions. In addition, a notch 221 is arranged on one side of the first channel 22 close to the second channel 23 in the same track body 21, so that the transmission member 51 passing through the first channel 22 can be connected to the sliding assembly 3. When the transmission member 51 rotates, it can drive the sliding assembly 3 to move. In this way, the sliding assembly 3 is driven to move in the same direction, thereby realizing the movement of the storage plate 4.

[0097] In some embodiments of the present invention, Figure 1-Figure 5 As shown, the two transmission members 51 move in opposite directions, the transmission member 51 passes through two of the guide rails 2, the first channels 22 in the two guide rails 2 are located on the same side of the second channel 23 in the same track body 21, and both ends of the transmission member 51 are located in the first channel 22 of one of the track bodies 21 and are connected to the sliding assembly 3 on the same side, and pass through the second channel 23 in the other track body 21.

[0098] The transmission member 51 is annular and is inserted into the first channel 22 in one track body 21 and the second channel 23 in the other track body 21. Both ends of the transmission member 51 in the length direction are arranged in the first channel 22 and connected to the sliding assembly 3. When the transmission member 51 rotates, it can drive the sliding assembly 3 to move. The movement directions of the two transmission members 51 are opposite. For example, it can be understood that one transmission member 51 rotates clockwise and the other transmission member 51 rotates counterclockwise, so that the sliding assemblies 3 on the two guide rails 2 can be driven to move in the same direction along the second direction at the same time, so that the stability of the storage plate 4 moving along the second direction can be ensured, and the structural design is reasonable.

[0099] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the two transmission members 51 move in opposite directions. The two transmission members 51 are formed in an annular shape. The rotating member 522 is located outside the outer peripheral wall of one of the annular transmission members 51 and inside the inner peripheral wall of the other annular transmission member 51. Parts of the two transmission members 51 are respectively arranged on both sides of the radial direction of the rotating member 522, and the two transmission members 51 are respectively engaged with the rotating member 522. Therefore, the driving motor 523 provides torque, which can drive the two transmission members 51 to move in opposite directions, thereby driving the sliding assemblies 3 on the two guide rails 2 to move in the same direction along the second direction, thereby ensuring the stability of the storage plate 4 moving in the second direction. It is possible to achieve that one driving motor 523 drives the two sliding assemblies 3 to move at the same time, which can save space and reduce weight, and is also conducive to reducing costs.

[0100] In some embodiments of the present invention, Fig.24 , Fig.25 and Fig.26 As shown, both ends of the transmission member 51 are located in the first channel 22 of one of the track bodies 21 and are connected to the sliding assembly 3 on the same side, and pass through the second channel 23 in the same track body 21 .

[0101] The transmission member 51 is arranged in the first channel 22 and the second channel 23 in the same track body 21 and is formed into a ring shape. The part of the transmission member 51 in the first channel 22 is connected to the sliding assembly 3, so that when the transmission member 51 rotates, it can drive the sliding assembly 3 to move. The movement directions of the two transmission members 51 are the same or opposite, so that the sliding assemblies 3 on the two guide rails 2 can be driven to move in the same direction along the second direction at the same time, thereby ensuring the stability of the storage plate 4 moving along the second direction, and the structural design is reasonable. The two transmission members 51 rotate in two different guide rails 2 respectively, which can avoid the two transmission members 51 from interfering with each other, thereby further improving the stability of the transmission.

[0102] The driving assembly 52 further includes a plurality of transmission wheels 525 , which are located on at least one of the two sides in the length direction of the guide rail 2 and are used to limit the movement trajectory of the transmission member 51 to improve the operation stability of the transmission member 51 .

[0103] For example, Fig.26 In the example shown, the transmission member 51 is arranged in the first channel 22 and the second channel 23 in the same track body 21 and is formed into a ring shape. The driving assembly 52 also includes a driving shaft 526, which is connected to the output shaft of the driving motor 523. The two transmission members 51 are arranged at intervals along the length direction of the driving shaft 526 and are both meshed and connected with the driving shaft 526. The driving shaft 526 can specifically be a synchronous belt, so that the driving motor 523 can provide torque to drive the driving shaft 526 to rotate. The driving shaft 526 can drive the two transmission members 51 meshed therewith to rotate in the same direction, thereby driving the sliding assemblies 3 on the two guide rails 2 to move in the same direction along the second direction, thereby ensuring the stability of the storage plate 4 moving along the second direction. It is possible to achieve that one driving motor 523 drives the two sliding assemblies 3 to move at the same time, which can save space and reduce weight, and is also conducive to reducing costs.

[0104] In some embodiments of the present invention, Fig.24 As shown, the two transmission members 51 move in the same direction, the first channels 22 in the two guide rails 2 are located on the same side of the second channel 23 in the same track body 21, there is one rotating member 522, and the two transmission members 51 are respectively engaged with the same rotating member 522. The two transmission members 51 are located as a whole on both sides of the radial direction of the rotating member 522, the transmission member 51 is formed in an annular shape, and the transmission member 51 can be specifically a belt-shaped cable, and the transmission members 51 are all located on the inner side of the inner circumferential wall of the two annular transmission members 51. Therefore, when the rotating member 522 rotates, the two transmission members 51 can be driven to move in the same direction as the rotating direction of the rotating member 522, and the first channels 22 on the two guide rails 2 are located on the same side of the second channel 23, so the sliding assembly 3 can move in the same direction along the second direction, thereby ensuring the stability of the storage plate 4 moving along the second direction, and the structural design is reasonable.

[0105] In some embodiments of the present invention, Fig.25As shown, the two transmission members 51 move in opposite directions, the first channels 22 in the two guide rails 2 are located on the side close to each other or on the side away from each other, the rotating members 522 are two mutually meshed, and the two transmission members 51 are respectively meshed with the two rotating members 522. The two transmission members 51 are located as a whole on both sides of the radial direction of the rotating member 522, the transmission member 51 is formed in an annular shape, and the transmission member 51 can be specifically a belt-shaped cable, and the two transmission members 51 are respectively located on the inner side of the inner circumferential wall of the two annular transmission members 51. Therefore, when the two meshed rotating members 522 rotate in opposite directions, the two transmission members 51 can be driven to move in opposite directions, and the first channels 22 on the two guide rails 2 are located on the side close to each other or on the side away from each other, so that the sliding assembly 3 can move in the same direction along the second direction, thereby ensuring the stability of the storage plate 4 moving along the second direction, and the structural design is reasonable.

[0106] In some embodiments of the present invention, Figure 3 , Figure 6 and Figure 7 As shown, the guide rail 2 is provided with a slide groove 24 extending along the length direction of the guide rail 2, and the slide groove 24 has an open opening 241, and the sliding assembly 3 at least partially extends into the slide groove 24 through the opening 241; the sliding assembly 3 also includes a bracket body 31 and a guide limit assembly 32, the bracket body 31 extends along the length direction of the guide rail 2, and the guide limit assembly 32 is connected to the bracket body 31, and at least a part of the guide limit assembly 32 is located in the slide groove 24. The guide limit assembly 32 can cooperate with the slide groove 24 through the opening 241 to achieve positioning and limiting functions, so that the guide limit assembly 32 moves along the length direction of the slide groove 24, that is, the sliding assembly 3 can be moved along the length direction of the guide rail 2.

[0107] Furthermore, if Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the guide limit assembly 32 includes rollers 35, and rollers 35 are provided at both ends of the length direction of the bracket body 31. The rollers 35 are rotatably connected to the bracket body 31 and are used to roll on the guide rail 2. The rollers 35 are rotatable, which can improve the smoothness and flexibility of the movement of the sliding assembly 3, and can reduce the friction of the sliding assembly 3 moving on the guide rail 2, thereby saving the driving force and energy consumption of the driving mechanism 5, which is conducive to improving the stability of the driving mechanism 5 driving the sliding assembly 3 to move.

[0108] In some embodiments of the present invention, Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the guide limit assembly 32 includes a first slider 33, at least part of which is disposed in the slide groove 24, one end of the first slider 33 is connected to the bracket body 31, and the other end is connected to the transmission member 51. Therefore, the first slider 33 has a transmission function, and can transmit the driving force of the driving mechanism 5 to the bracket body 31, so that the driving mechanism 5 can drive the sliding assembly 3 to move.

[0109] Specifically, the driving mechanism 5 includes a transmission member 51 and a driving assembly 52. ​​There are two transmission members 51, and the two transmission members 51 are respectively connected to two of the sliding assemblies 3. There is one driving assembly 52, which is used to simultaneously drive the two transmission members 51 to drive the sliding assembly 3 to move. The transmission member 51 is inserted into the slide slot 24, so that the end of the first sliding block 33 extending into the slide slot 24 can be connected to the transmission member 51. When the driving assembly 52 drives the transmission member 51 to move, the transmission member 51 can drive the sliding assembly 3 to move through the first sliding block 33. The structure is simple and the arrangement is reasonable, which can ensure the stability of the transmission.

[0110] Among them, the first slider 33 is detachably connected to the bracket body 31. The first slider 33 can be first connected to the driving mechanism 5 and then connected to the bracket body 31, which can reduce the difficulty of assembly and disassembly, thereby improving assembly efficiency and facilitating later maintenance or replacement of parts.

[0111] In some embodiments of the present invention, Figure 2 , Figure 3 , Figure 6-Figure 7 and Figure 20-23 As shown, a baffle 231 is provided on one side of the second channel 23 close to the first channel 22, and the baffle 231 extends along the length direction of the guide rail 2. The width of the end of the first slider 33 connected to the transmission member 51 is greater than the distance between the baffle 231 and the first channel 22, thereby preventing the end of the first slider 33 connected to the driving mechanism 5 from escaping from the opening of the slide rail.

[0112] Further, in some embodiments of the present invention, Fig. 20 and Fig. 22 As shown, the first slider 33 includes: a body 331 and a protrusion 332, one end of the body 331 is connected to the bracket body 31, and the other end is connected to the protrusion 332; the protrusion 332 is connected to the transmission member 51, and the side surface of the protrusion 332 close to the bracket body 31 is suitable for abutting against the baffle 231. The baffle 231 can position and limit the protrusion 332, preventing the protrusion 332 from escaping from the gap between the baffle 231 and the first channel 22, and can improve the stability and reliability of the sliding assembly 3 moving on the guide rail 2.

[0113] In some embodiments of the present invention, Figure 2 , Figure 3 , Figure 6-Figure 7 and Figure 20-23 As shown, the side surface of the protrusion 332 close to the bracket body 31 is provided with a first elastic groove 3321 and a first elastic bridge 3322, the two ends of the first elastic bridge 3322 in the length direction are connected to the two opposite side walls of the first elastic groove 3321, the first elastic bridge 3322 is spaced apart from the bottom wall of the first elastic groove 3321, and the first elastic bridge 3322 has a first bulge 3323 protruding away from the bottom wall of the first elastic groove 3321. Through the cooperation of the first elastic groove 3321 and the first elastic bridge 3322, the middle area of ​​the first elastic bridge 3322 in the length direction can be slightly deformed, so that it can better adapt to the movement of the sliding assembly 3 on the guide rail 2, so that the first bulge 3323 on the first elastic bridge 3322 is better abutted against the baffle 231, thereby better improving the stability of the sliding assembly 3 moving on the guide rail 2.

[0114] In some embodiments of the present invention, Figure 2 , Figure 3 , Figure 6-Figure 7 and Figure 20-23 As shown, the guide limit assembly 32 includes a second slider 34, and the second slider 34 includes a connecting portion 341 and a limit portion 342. One end of the connecting portion 341 is connected to the bracket body 31, and the other end is connected to the limit portion 342. Figure 1 and Figure 2 The limit portion 342 is disposed between the top wall of the slide slot 24 and the second channel 23 and the first channel 22. The width of the limit portion 342 extending along the first direction is greater than the width of the opening 241 along the first direction. The side surface of the limit portion 342 close to the connecting portion 341 is suitable for abutting against the inner top wall of the slide slot 24. The first direction, the second direction and the up-down direction are perpendicular to each other.

[0115] The connecting portion 341 facilitates connecting the limiting portion 342 with the bracket body 31. The limiting portion 342 cooperates with the top wall of the slide groove 24 to achieve positioning and limiting functions in the up and down directions, and can prevent the limiting portion 342 from escaping from the opening 241 of the slide groove 24, thereby preventing the sliding component 3 from detaching from the guide rail 2, and can improve the stability and reliability of the sliding component 3 moving on the guide rail 2.

[0116] In some embodiments of the present invention, Figure 2 , Figure 3 , Figure 6-Figure 7 and Figure 20-23As shown, the side surface of the limiting portion 342 close to the connecting portion 341 is provided with a second elastic groove 3421 and a second elastic bridge 3422, the two ends of the second elastic bridge 3422 in the length direction are connected to the two opposite side walls of the second elastic groove 3421, the second elastic bridge 3422 is spaced apart from the bottom wall of the second elastic groove 3421, and the second elastic bridge 3422 has a second bulge 3423 protruding in the direction away from the bottom wall of the second elastic groove 3421. Through the cooperation of the second elastic groove 3421 and the second elastic bridge 3422, the middle area of ​​the second elastic bridge 3422 in the length direction can be slightly deformed, so that the sliding assembly 3 can be better adapted to the movement on the guide rail 2, so that the second bulge 3423 on the second elastic bridge 3422 is better abutted against the top wall of the slide groove 24, so as to better improve the stability of the sliding assembly 3 moving on the guide rail 2.

[0117] In some embodiments of the present invention, Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the roller 35 includes a wheel body 351 and a cam portion 352, the wheel body 351 is rotatably connected to the bracket body 31, the outer peripheral wall of the wheel body 351 abuts against the upper surface of the guide rail 2, the cam portion 352 is arranged on the outer peripheral wall of the wheel body 351 and extends along the circumferential direction of the wheel body 351, and the cam portion 352 extends into the slide groove 24 through the opening 241. The cam portion 352 can roll on the upper surface of the guide rail 2, which can improve the smoothness and flexibility of the movement of the sliding assembly 3, and can reduce the friction force of the sliding assembly 3 moving on the guide rail 2, thereby saving the driving force and energy consumption of the driving mechanism 5. The cam portion 352 extends into the slide groove 24 through the opening 241, and can play a positioning and limiting role along the first direction, thereby ensuring that the roller 35 rolls along the length direction of the guide rail 2, that is, the second direction, and further ensuring that the sliding assembly 3 moves along the second direction on the guide rail 2.

[0118] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, the widths of both ends of the bracket body 31 in the length direction are greater than the width of the middle region in the length direction of the bracket body 31. Therefore, the structural strength of the middle region in the length direction of the bracket body 31 is relatively low. When the luggage compartment assist device 1000 is applied to the luggage compartment at the rear of the vehicle, when the rear of the vehicle is hit, the bracket body 31 receives the impact force, and the middle region in the length direction thereof will bend, thereby preventing the sliding assembly 3 from hitting the passenger compartment of the vehicle as a whole and causing casualties. The collision safety design of the vehicle can be strengthened, thereby reducing safety hazards and improving the safety of users.

[0119] In some embodiments of the present invention, Figure 8 , Fig. 9 and Fig.10As shown, the storage plate 4 is connected to the sliding assembly 3 by snapping. In this way, the connection stability between the storage plate 4 and the sliding assembly 3 can be ensured, and the storage plate 4 and the sliding assembly 3 can be detachably connected, which is convenient for later maintenance or replacement, and the snap connection is convenient for assembly and disassembly, which can improve the convenience of use for users.

[0120] In some embodiments of the present invention, Figure 8 , Fig. 9 and Fig.10 As shown, a limit block 36 is provided on the sliding assembly 3, and an insert block 41 is provided on the storage plate 4. One of the limit block 36 and the insert block 41 is provided with an insertion groove 411, and the other of the limit block 36 and the insert block 41 is provided with an insert portion 360. The insert portion 360 is inserted into the insert groove 411 to insert the insert block 41 with the limit block 36, so that the sliding assembly 3 and the storage plate 4 can be detachably connected.

[0121] Specifically, Fig. 9 and Fig.10 In the example shown, a plug-in slot 411 is provided on the plug-in block 41, and a plug-in portion 360 is provided on the limit block 36. The plug-in slot 411 is open at one end along the second direction. The plug-in portion 360 can be inserted into the plug-in slot 411 through the open mouth 241 of the plug-in slot 411 along the second direction, thereby realizing a plug-in connection between the plug-in block 41 and the limit block 36, and further realizing a detachable connection between the storage plate 4 and the sliding assembly 3. The operation is simple and convenient, which can improve the assembly efficiency and facilitate disassembly.

[0122] In some embodiments of the present invention, Figure 8 , Fig. 9 and Fig.10 As shown, one of the inner walls of the plug-in portion 360 and the plug-in slot 411 is provided with a groove 361 and a limiting spring bridge 362, the two ends of the limiting spring bridge 362 in the length direction are connected to the two side walls opposite to the groove 361, the limiting spring bridge 362 is spaced apart from the bottom wall of the groove 361, the limiting spring bridge 362 has a protrusion 363 protruding in the direction away from the bottom wall of the groove 361, and the other of the inner walls of the plug-in portion 360 and the plug-in slot 411 is provided with a limiting groove 412 that cooperates with the protrusion 363.

[0123] The protrusion 363 on the limiting spring bridge 362 can be inserted into the limiting groove 412, and can play a role of limiting and positioning in the second direction. The limiting block 36 is limited in the plug-in block 41, and the connection stability between the plug-in block 41 and the limiting block 36 can be improved. By setting the groove 361 and the limiting spring bridge 362, the middle area of ​​the length direction of the limiting spring bridge 362 can be deformed, so that the movement of the protrusion 363 can be achieved. Therefore, when the plug-in part 360 is inserted into the plug-in slot 411 through the open mouth 241 of the plug-in slot 411 along the second direction, the limiting spring bridge 362 can make the protrusion 363 move slightly, thereby playing a role of avoiding, so that the plug-in part 360 can be smoothly inserted into the plug-in slot 411, which can effectively reduce the difficulty of assembly and save labor for the operator.

[0124] In some embodiments of the present invention, Figure 8 , Fig. 9 and Fig.10 As shown, there are multiple limit spring bridges 362, and the limit slots 412 are multiple, corresponding to the multiple limit spring bridges 362. The multiple protrusions 363 on the limit spring bridges 362 can be matched with the multiple limit slots 412 one by one, so that the limit block 36 and the plug block 41 form a snap connection at multiple locations, which can further improve the connection stability between the limit block 36 and the plug block 41. It can also reduce the stress on each limit spring bridge 362 and the limit slot 412, so as to avoid wear caused by excessive stress, and further improve the service life of the limit block 36 and the plug block 41.

[0125] In some embodiments of the present invention, Figure 8 , Fig. 9 and Fig.10 As shown, the plug-in slot 411 includes a first slot 4111 and a second slot 4112, the first slot 4111 extends along the second direction, and the lower side wall of the first slot 4111 is provided with a second slot 4112, the plug-in portion 360 includes a first portion 364 and a second portion 365, the first portion 364 cooperates with the first slot 4111, and the second portion 365 cooperates with the second slot 4112, a plurality of limiting slots 412 include a first limiting slot 4121 located on the lower side wall of the first slot 4111 and a second limiting slot 4122 located on the side wall of the second slot 4112, a plurality of limiting spring bridges 362 include a first limiting spring bridge 3621 located on the lower surface of the first portion 364 and cooperates with the first limiting slot 4121, and a second limiting spring bridge 3622 located on the side wall of the second portion 365 and cooperates with the second limiting slot 4122.

[0126] It can be understood that the first groove 4111 and the first part 364 can achieve limitation and positioning in the up and down directions, the second groove 4112 and the second part 365 can achieve limitation and positioning in the first direction, the first limiting groove 4121 cooperates with the first limiting spring bridge 3621 and the second limiting groove 4122 cooperates with the second limiting spring bridge 3622 to achieve multiple snap-in connections, thereby achieving limitation and positioning of the limiting block 36 and the plug-in block 41 in the second direction, thereby ensuring the connection stability between the limiting block 36 and the plug-in block 41 in all directions.

[0127] In some embodiments of the present invention, Figure 8 , Fig. 9 and Fig.10 As shown, there are two first limiting grooves 4121 and they are located on both sides of the second groove 4112 along the first direction, two second limiting grooves 4122 and they are respectively arranged on the two opposite side walls of the second groove 4112, two first limiting spring bridges 3621 and they are respectively located on both sides of the second part 365 along the first direction, and two second limiting spring bridges 3622 and they are respectively arranged on the two opposite side walls of the second part 365 along the first direction. In this way, the snap connection can be realized in multiple places, further improving the connection stability between the limiting block 36 and the plug-in block 41. It can also reduce the stress on each limiting spring bridge 362 and the limiting groove 412, thereby avoiding wear caused by excessive stress, and further improving the service life of the limiting block 36 and the plug-in block 41.

[0128] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the bottom plate 1 is provided with a mounting groove 11, the guide rail 2 is arranged in the mounting groove 11, and the upper surface of the guide rail 2 is flush with the upper surface of the bottom plate 1. The guide rail 2 can be hidden in the bottom plate 1, which can prevent the guide rail 2 from protruding from the upper surface of the bottom plate 1, causing the objects in the suitcase to be easily bumped by the guide rail 2 or difficult to move, thereby improving convenience. At the same time, the height of the storage plate 4 can also be reduced, and the flatness and appearance of the bottom plate 1 can be improved.

[0129] In some embodiments of the present invention, Figure 2 and Fig.11 As shown, the guide rail 2 is connected to the base plate 1 through a connecting piece 27. A plurality of mounting holes 25 are provided on the guide rail 2. The plurality of mounting holes 25 are spaced apart along the second direction. The connecting pieces 27 are a plurality corresponding to the plurality of mounting holes 25. Along the second direction, the connecting pieces 27 that cooperate with some mounting holes 25 closest to the inner side of the luggage compartment are screws, and the connecting pieces 27 that cooperate with other mounting holes 25 are buckles.

[0130] Multiple connectors 27 can ensure the connection stability between the guide rail 2 and the bottom plate 1. The installation hole 25 closest to the inside of the trunk is the main positioning hole. Here, the guide rail 2 is connected to the bottom plate 1 by screws. The screws can enhance the tightness of the connection. When the rear of the vehicle is hit, the screws can firmly nail the guide rail 2 to the bottom plate 1 to prevent the guide rail 2 from hitting the passenger compartment of the vehicle and causing casualties. The other multiple installation holes 25 are connected by snap-fits. The snap-fits are specifically male and female buckles. The male and female buckles connect the guide rail 2 to the bottom plate 1 by snapping. While ensuring the connection stability, when the rear of the vehicle is hit, the male and female buckles will be detached from the installation hole 25 after being impacted, which is conducive to the bending of the guide rail 2 under force, thereby better avoiding the guide rail 2 from hitting the passenger compartment of the vehicle as a whole and causing casualties. The collision safety design of the vehicle can be strengthened, thereby reducing safety hazards and improving the safety of users.

[0131] In some embodiments of the present invention, Fig.11 As shown, the lower surface of the guide rail 2 is provided with a weakened groove 26, and the weakened groove 26 is arranged at intervals along the length direction of the guide rail 2. The weakened groove 26 can be specifically in the shape of a slit, and the structural strength of the guide rail 2 at the weakened groove 26 is weakened. By providing multiple weakened grooves 26, when the rear of the vehicle is hit, the guide rail 2 is forced to fold at multiple weakened grooves 26, so that the guide rail 2 can be collapsed, which can prevent the guide rail 2 from hitting the passenger compartment of the vehicle straightly as a whole and causing casualties, and can strengthen the collision safety design of the vehicle, thereby reducing safety hazards and improving the safety of users. Among them, the number of weakened grooves 26 on each guide rail 2 can be two, three, four or five, etc., and this application does not make specific restrictions on this.

[0132] In some embodiments of the present invention, Fig.11 As shown, the end of the guide rail 2 closest to the inside of the luggage compartment is connected to the bottom plate 1 by screws, and there are three weakened grooves 26, one of which is provided at the end of the guide rail 2 close to the inside of the luggage compartment, and the three weakened grooves 26 are provided at equal intervals along the length direction of the guide rail 2. The three weakened grooves 26 roughly divide the guide rail 2 into three sections, and the screws can enhance the connection tightness between the end of the guide rail 2 closest to the inside of the luggage compartment and the bottom plate 1. When the rear of the vehicle is hit, the screws can firmly nail the end of the guide rail 2 closest to the inside of the luggage compartment to the bottom plate 1, and the guide rail 2 is folded at the three weakened grooves 26 under force, so that the guide rail 2 can be collapsed, and the amount of collapse is greater than or equal to one-half of the total length of the guide rail 2, effectively preventing the guide rail 2 from collided straightly into the passenger compartment of the vehicle as a whole to cause casualties, and can strengthen the collision safety design of the vehicle, thereby reducing safety hazards and improving the safety of users.
