[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the singular forms "a", "an" and "the" include plural references unless the context clearly dictates otherwise.

[0037] Some embodiments of the application are described in detail. The following embodiments and features of the embodiments can be combined with each other, without conflict.

[0038] Reference is made to Figure 1 The embodiment provides a vehicle 200, comprising a vehicle body 201 and a rear assembly 100. The rear assembly 100 is connected to a rear end of the vehicle body 201.

[0039] For the convenience of description, a first direction Y, a second direction X and a third direction Z are introduced below to describe the embodiments of the application. The first direction Y, the second direction X and the third direction Z can be three straight line directions that are not parallel to each other in space. For example, the first direction Y, the second direction X and the third direction Z can be three perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). In subsequent embodiments, for the convenience of understanding, after the rear assembly 100 is installed on the vehicle 200, the first direction Y is substantially parallel to the width direction of the vehicle 200, the second direction X is substantially parallel to the length direction of the vehicle 200, and the third direction Z is substantially parallel to the height direction of the vehicle 200.

[0040] In some embodiments, it is provided that Figure 2 and Figure 3 The rear assembly 100 comprises a side wall assembly 10, a tailgate assembly 20 and a safety belt retractor 30. The tailgate assembly 20 is connected to the side wall assembly 10. The safety belt retractor 30 is detachably connected to the tailgate assembly 20, and the safety belt retractor 30 and the side wall assembly 10 are spaced apart along the first direction Y and define a receiving space Q1 for receiving a target piece 90.

[0041] According to the rear assembly 100 of the embodiment, the accommodation space Q1 formed between the seat belt retractor 30 and the side wall assembly 10 can be used to accommodate the target member 90, so as to facilitate the addition of other devices in the rear assembly 100 to meet the functional requirements of different vehicle models. The target member 90 can be configured as an air conditioning device. The air conditioning device can include an air conditioning body 91 and an air duct 92, and the air duct 92 is arranged above the air conditioning body 91 along the height direction of the vehicle 200. The seat belt retractor 30 is detachably mounted on the tailgate assembly 20, so that the mounting position of the seat belt retractor 30 can be adjusted according to different vehicle models to ensure that the installation of the seat belt retractor 30 and different target members 90 will not interfere with each other, thereby ensuring the stable operation of the seat belt retractor 30 and improving the use reliability of the seat belt 70.

[0042] Therefore, the rear assembly 100 of the embodiment can improve the mounting versatility of the seat belt retractor 30.

[0043] In some embodiments, referring to Figure 2 , the rear assembly 100 further includes a seat belt 70 connected with the seat belt retractor 30 and capable of being retracted to accommodate the seat belt 70 or pulled out for the occupant to use under the driving of the seat belt retractor 30.

[0044] In some embodiments, referring to Figure 3 and Figure 4 , the target member 90 and the seat belt retractor 30 are arranged staggered along the first direction Y, and the target member 90 and the seat belt retractor 30 are arranged staggered along the second direction X.

[0045] In this way, when the vehicle 200 is normally driven, the target member 90 and the seat belt retractor 30 do not interfere with each other, thereby improving the utilization rate of the interior space of the vehicle 200. In addition, since the seat belt retractor 30 and the target member 90 are arranged staggered along the first direction Y and the second direction X, when the tailgate assembly 20 and / or the side wall assembly 10 are impacted, the target member 90 is less likely to collide with the seat belt retractor 30 during the displacement of the target member 90 to the interior space of the vehicle 200 under the action of the impact force, thereby reducing the possibility of damage to the seat belt retractor 30, reducing the risk of failure, and improving the operation stability of the seat belt retractor 30 and the seat belt 70.

[0046] Specifically, the target member 90 and the seat belt retractor 30 arranged staggered along the first direction Y means that the projections of the target member 90 and the seat belt retractor 30 along a direction perpendicular to the first direction Y (for example, the second direction X) are arranged staggered along the first direction Y. The target member 90 and the seat belt retractor 30 arranged staggered along the second direction X means that the projections of the target member 90 and the seat belt retractor 30 along a direction perpendicular to the second direction X (for example, the first direction Y) are arranged staggered along the second direction X.

[0047] In some embodiments, the target object 90 is an air conditioner. The air conditioner includes an air conditioner body 91 and an air duct 92, which is arranged above the air conditioner body 91 along the third direction Z (i.e., the height direction of the vehicle 200).

[0048] In some embodiments, the vehicle 200 has multiple rows of seats, and the seat belt retractor 30 is used to retract the seat belt 70 mounted on the last row of seats located rearward along the third direction Z. In other embodiments, the vehicle 200 can have two, three, or more rows of seats. In the present embodiment, the vehicle 200 has three rows of seats, and the seat belt retractor 30 is detachably mounted on the D-pillar member of the tailgate assembly 20.

[0049] In some embodiments, referring to Figure 3 and Figure 4 , the tailgate assembly 20 defines a door opening K1, and the projection of the seat belt retractor 30 on the tailgate assembly 20 (i.e., the projection along the second direction X) is offset from the door opening K1 along the first direction Y. In this way, when the rear assembly 100 is impacted, the tailgate assembly 20 can protect the seat belt retractor 30, reducing the likelihood of damage to the seat belt retractor 30 and improving the safety of the seat belt retractor 30.

[0050] In some embodiments, referring to Figure 3 and Figure 4 , the tailgate assembly 20 includes a first side portion 21 and a second side portion 22. The first side portion 21 extends along the first direction Y, and the second side portion 22 is bent and connected to the first side portion 21 and extends along the second direction X, which intersects the first direction Y. The second side portion 22 is configured as the edge of the door opening K1. Along the first direction Y, the projection of the seat belt retractor 30 along the second direction X is located on the first side portion 21. In this way, when the rear assembly 100 is impacted, the second side portion 22 or the side of the first side portion 21 away from the second side portion 22 is first subjected to the impact force, and the first side portion 21 close to the second side portion 22 is less likely to be first impacted. Thereafter, the impact on the tailgate assembly 20 is transmitted to the seat belt retractor 30, which can significantly reduce the likelihood of the seat belt retractor 30 being impacted and damaged, thereby ensuring the reliability of the seat belt 70 being secured to the tailgate assembly 20 by the seat belt retractor 30, reducing the likelihood of failure of the seat belt 70, and further ensuring the safety of the occupants when the rear assembly 100 is impacted.

[0051] In some embodiments, the number of first side portions 21 is two, and the two first side portions 21 are spaced apart along the first direction Y. The number of second side portions 22 is two, and the two second side portions 22 are spaced apart along the first direction Y. Referring to Figure 3The tailgate assembly 20 further comprises a first top portion 23 and a second top portion 24. The first top portion 23 and the second top portion 24 both extend along the first direction Y, and the second top portion 24 is connected to the first top portion 23 by bending and extends along the second direction X. The two ends of the first top portion 23 are connected to the two first side portions 21 respectively, and the two ends of the second top portion 24 are connected to the two second side portions 22 respectively. In this way, the first top portion 23, the second top portion 24, the two first side portions 21 and the two second side portions 22 jointly form the tailgate assembly 20, and the four portions jointly form a door opening K1 for mounting the tailgate.

[0052] In other embodiments, the seat belt retractor 30 can be detachably mounted to the first top portion 23 and / or the second top portion 24.

[0053] In some embodiments, referring to Figure 4 The seat belt retractor 30 comprises a connecting assembly 53. The connecting assembly 53 is detachably connected to the tailgate assembly 20 by a fastening structure 80, and the position of the seat belt retractor 30 along a third direction Z relative to the tailgate assembly 20 is adjustably arranged. The third direction Z intersects the first direction Y, and the third direction Z intersects the second direction X. In this way, the position of the seat belt retractor 30 along the third direction Z can be adjusted according to the height of the different vehicle models along the third direction Z, the height of the seat along the third direction Z and the height of the target object 90 along the third direction Z, so as to improve the installation versatility of the seat belt retractor 30.

[0054] In some embodiments, referring to Figure 4 and Figure 5 The connecting assembly 53 comprises a first connecting portion 531 and a second connecting portion 532. The fastening structure 80 comprises a first fastener 81 and a second fastener 82. The first connecting portion 531 is located on one side of the first side portion 21 along the second direction X, and is detachably connected to the first side portion 21 by the first fastener 81. The second connecting portion 532 extends to one side of the second side portion 22 along the first direction Y, and is detachably connected to the second side portion 22 by the second fastener 82. In this way, the fastening structure 80 can fix the connecting assembly 53 to the tailgate assembly 20 along different directions, so as to improve the connection reliability of the seat belt retractor 30 and the tailgate assembly 20.

[0055] The first fastener 81 and the second fastener 82 can be bolts, pins or other fasteners, so as to realize convenient disassembly and assembly.

[0056] In some embodiments, referring to Figure 4 The first connecting portion 531 extends along the first direction Y close to the side wall assembly 10. Referring to Figure 5 and Figure 6The connecting assembly 53 further comprises a third connecting portion 533. The fastening structure 80 further comprises a third fastener 83. The third connecting portion 533 extends downward along the third direction Z. The third connecting portion 533 is located between the first connecting portion 531 and the second connecting portion 532 along the first direction Y. In this way, the seat belt winding device 30 is fixed to the tailgate assembly 20 in three directions, further improving the fixing reliability of the seat belt winding device 30 on the tailgate assembly 20. The third fastener 83 can be a bolt, a pin, or the like, to facilitate disassembly and assembly.

[0057] In some embodiments, referring to Figure 4 and Figure 5 , the seat belt winding device 30 comprises a mounting assembly 50 and a winder 40. The mounting assembly 50 is detachably connected to the tailgate assembly 20, and the mounting assembly 50 defines a mounting slot C1 in which the winder 40 is installed. The mounting slot C1 has a first opening K71 open along the second direction X, and the tailgate assembly 20 covers the first opening K71. In this way, by covering the first opening K71 of the mounting slot C1 with the tailgate assembly 20, the material cost of the mounting assembly 50 can be reduced, and the weight of the mounting assembly 50 can be reduced.

[0058] In some embodiments, referring to Figure 4 and Figure 5 , the mounting slot C1 further has a second opening K72 open upward along the third direction Z, and the winder 40 is arranged in the mounting slot C1 and extends out of the second opening K72. The rear assembly 100 comprises a hanging piece 60 spaced apart from the seat belt winding device 30 along the third direction Z, and the hanging piece 60 is configured to hang the seat belt 70 connected to the winder 40.

[0059] In this way, the hanging piece 60 can guide the seat belt 70, change the extension direction of the seat belt 70, and facilitate connection with the seat belt buckle on the seat. In addition, since the seat belt 70 is connected to the winder 40 along the third direction Z, the arrangement space of the seat belt winding device 30 in the second direction X and the first direction Y can be reduced, thereby improving the utilization rate of the interior space of the vehicle 200.

[0060] In some embodiments, referring to Figure 4 , the hanging piece 60 is detachably connected to the tailgate assembly 20 by a fourth fastener 84 and is connected to the first side portion 21 of the tailgate assembly 20, and the hanging piece 60 is adjustably arranged relative to the tailgate assembly 20 along the third direction Z. In this way, the mounting position of the hanging piece 60 can be adjusted according to the mounting position of the mounting assembly 50, to ensure reliable guidance of the seat belt 70 by the hanging piece 60.

[0061] In some embodiments, the safety belt 70 can pass through one side of the hanger 60 to the other side of the hanger 60, and the extension direction of the safety belt 70 is changed.

[0062] In some embodiments, referring to Figure 5 and Figure 6 , the mounting assembly 50 includes a support portion 51 and a surrounding wall 52.

The surrounding wall 52 defines a second opening K72 away from one side of the support portion 51 along the third direction Z. The surrounding wall 52 and the support portion 51 define a first opening K71 between one end of the surrounding wall 52 close to the tailgate assembly 20 along the second direction X and the support portion 51.

[0063] In some embodiments, the surrounding wall 52 and the support portion 51 are integrally formed to improve the overall strength of the mounting assembly 50 and the stability of the mounting assembly 50 to carry the retractor 40.

[0064] In some embodiments, referring to Figure 5 and Figure 6 , the surrounding wall 52 includes a first edge portion 521, a second edge portion 522, and a third edge portion 523. The first edge portion 521 and the second edge portion 522 are arranged to be spaced apart along the first direction Y. The third edge portion 523 is located at one end of the support portion 51 along the second direction X. The third edge portion 523 is connected to the first edge portion 521 and the second edge portion 522 at two ends of the third edge portion 523 along the first direction Y, respectively.
