The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present application. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0044] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0045] Embodiment 1

[0046] See also Figure 1 The present embodiment provides a vehicle 200, including a vehicle body 201 and a rear assembly 100. The vehicle body 201 defines a space inside the vehicle. The rear assembly 100 is connected to the vehicle body 201.

[0047] See also Figures 1 to 4 The rear assembly 100 includes a tailgate 10, a mounting member 20 and a bearing member 30. The tailgate 10 is rotatably connected to the roof of the vehicle body 201, and the rotation axis of the tailgate 10 is parallel to the width direction Y of the vehicle 200. In other embodiments, the tailgate 10 can also be configured as a side-opening tailgate, a hatchback tailgate, a floor-to-ceiling tailgate and other structures.

[0048] See also Figure 1 The tailgate 10 is rotatably connected to the vehicle body 201, and the vehicle body 201 defines the interior space of the vehicle (not shown in the figure). Figures 2 to 4 The mounting member 20 is fixed to the side of the tailgate 10 facing the interior space of the vehicle, and a mounting cavity Q is formed between the mounting member 20 and the tailgate 10, and the mounting cavity Q has an opening K. The bearing member 30 is movably connected to the mounting member 20 along the first direction M, and the bearing member 30 has a bearing surface P, and the bearing member 30 has a storage position and an extended position. Figure 3 , the carrier 30 is in the storage position, and the carrier 30 is located in the installation cavity Q. Figure 4 , the carrier 30 is in the extended position, the carrier 30 extends from the opening K, and the bearing surface P is exposed relative to the mounting member 20 , and the bearing surface P is used to bear the target member 300 .

[0049] The rear assembly 100 of this embodiment, the mounting part 20 is installed on the side of the tailgate 10 facing the interior space of the vehicle, so that the surface of the tailgate 10 facing the exterior space of the vehicle remains intact, thereby not damaging the appearance of the vehicle 200 and not affecting the wind resistance performance of the vehicle 200, thereby ensuring the appearance integrity of the vehicle 200 and the NVH performance of the vehicle 200.

[0050] The carrier 30 can switch between a storage position and an extended position relative to the mounting member 20. When the carrier 30 is in the storage position, the carrier 30 located in the mounting cavity Q can store the target member 300. When the carrier 30 is in the extended position, the carrier 30 can expose the target member 300 to the external space of the vehicle 200 so that the user can use the target member 300. At the same time, compared with the method of directly setting the carrier 30 on the tailgate 10, the additionally set mounting member 20 can improve the strength of the rear assembly 100 to ensure the structural stability of the tailgate 10.

[0051] Therefore, the rear assembly 100 of the present embodiment can take into account the mounting requirements of the target component 300 and ensure the NVH performance of the vehicle 200 .

[0052] In some embodiments, the target part 300 is a vehicle-mounted aircraft, such as a drone 301. In other embodiments, the target part 300 can also be configured as a small vehicle, etc. When the drone 301 needs to work, the tailgate 10 rotates to a set angle with the vehicle body 201, and makes the bearing surface P of the bearing part 30 substantially perpendicular to the height direction Z of the vehicle 200 (for example, the angle between the height direction Z of the vehicle 200 and the bearing surface P is between 80° and 90°), and then controls the bearing part 30 to move to the extended position, so that the bearing surface P is exposed to the external space of the vehicle 200, so as to be used as a lifting platform for the drone 301.

[0053] In some embodiments, when the carrier 30 is in the storage position, the carrier 30 is located inside the opening K to ensure storage protection for the target part 300 .

[0054] In some embodiments, see Figure 3 The rear assembly 100 further includes a driving structure 89. The driving structure 89 is connected between the vehicle body 201 and the tailgate 10 to drive the tailgate 10 to rotate relative to the vehicle body 201. The driving structure 89 can be configured as an electric push rod or an electric hydraulic cylinder.

[0055] In some embodiments, see Figure 4 , the rear assembly 100 also includes an interface module 83. The interface module 83 is connected to the carrier 30 and is located on the side of the first enclosure portion 32 facing away from the opening K. The interface module 83 is used to dock with the target part 300, and charge the target part 300 or transmit signals. The interface module 83 can be connected to the battery module of the vehicle 200 or to the vehicle controller of the vehicle 200 through a wiring harness, so that the user can control the target part 300 and charge the target part 300. The specific structure of the interface module 83 can refer to the existing charging interface or communication interface, which will not be repeated here.

[0056] In some embodiments, see Figure 4 and Figure 5 The bearing member 30 includes a first bottom plate 31 and a first enclosing plate portion 32. The first enclosing plate portion 32 is connected to the periphery of the first bottom plate 31. The first enclosing plate portion 32 is spaced apart from the tailgate 10. Along the length direction X of the vehicle 200, the distance between the side of the first enclosing plate portion 32 away from the rear of the vehicle and the tailgate 10 is smaller than the distance between the side of the first enclosing plate portion 32 close to the rear of the vehicle and the tailgate 10. A bearing groove C5 is formed between the first enclosing plate portion 32 and the first bottom plate 31, and the bearing groove C5 is used to bear the target member 300. The surface of the first bottom plate 31 is formed as a bearing surface P.

[0057] In this way, the carrier 30 will not interfere with the tailgate 10 when moving between the storage position and the extended position, thereby ensuring the switching reliability of the carrier 30 between the storage position and the extended position.

[0058] In some embodiments, see Figure 4 and Figure 5 The mounting member 20 includes a second bottom plate 21 and a second enclosing plate portion 22. The second bottom plate 21 is spaced apart from the tailgate 10. One side of the second enclosing plate portion 22 is connected to the second bottom plate 21, and the other side of the second enclosing plate portion 22 is connected to the tailgate 10. The second bottom plate 21, the second enclosing plate portion 22 and the tailgate 10 together form a mounting cavity Q. The two ends of the second enclosing plate portion 22 are spaced apart and are configured with the second bottom plate 21 and the tailgate 10 to form an opening K. The bearing member 30 is movably connected to the second bottom plate 21.

[0059] In some embodiments, see Figure 5 The first enclosure portion 32 includes a first side plate 321, a second side plate 322, a third side plate 323, and a fourth side plate 324. Along the length direction X of the vehicle 200, the first side plate 321 is connected to the side of the first bottom plate 31 away from the rear of the vehicle, and the second side plate 322 is connected to the side of the first bottom plate 31 close to the rear of the vehicle. Along the width direction Y of the vehicle 200, the third side plate 323 is connected to one side of the first bottom plate 31, and the fourth side plate 324 is connected to the other side of the first bottom plate 31.

[0060] In some embodiments, see Figure 5 The second enclosing plate portion 22 includes a fifth side plate 221, a sixth side plate 222 and a seventh side plate 223. The fifth side plate 221 is connected to a side of the second bottom plate 21 away from the opening K. The sixth side plate 222 and the seventh side plate 223 are spaced apart, one end of the sixth side plate 222 is connected to one end of the fifth side plate 221, and one end of the seventh side plate 223 is connected to the other end of the fifth side plate 221. The other end of the sixth side plate 222 and the other end of the seventh side plate 223 are spaced apart and define the opening K.

[0061] The height of the sixth side plate 222 is greater than the height of the first side plate 321 , and the height of the sixth side plate 222 is greater than the height of the second side plate 322 .

[0062] In some embodiments, see Figure 6 The rear assembly 100 also includes a first drive component 40, one end of the first drive component 40 is connected to the mounting member 20, and the other end of the first drive component 40 is connected to the supporting member 30. The first drive component 40 is used to drive the supporting member 30 to move between the storage position and the extended position.

[0063] In some embodiments, the first drive assembly 40 may be configured as an electric push rod or an electric hydraulic cylinder. The driving direction of the first drive assembly 40 may be set to a first direction M, a second direction N, or other directions, and the second direction N intersects the first direction M. The second direction N may be configured to be parallel to the width direction Y of the vehicle 200.

[0064] In some embodiments, see Figure 6 The first driving assembly 40 is fixed to the side of the second bottom plate 21 facing away from the opening K, and the first driving assembly 40 includes a motor 41 and an output shaft 42. The motor 41 is connected to the second bottom plate 21 of the mounting member 20. The output shaft 42 extends along the second direction N and is transmission-connected between the motor 41 and the transmission assembly 60.

[0065] See also Figure 6 The rear assembly 100 further includes a transmission assembly 60, which is transmission-connected between the first drive assembly 40 and the carrier 30, and is transmission-coordinated with the output shaft 42. The transmission assembly 60 is used to switch the driving direction of the first drive assembly 40 to the first direction M, so as to drive the carrier 30 to move along the first direction M. In this way, the space of the mounting cavity Q can be fully utilized, and the width dimension of the mounting member 20 will not be affected, so as to meet the mounting requirements of more target members 300. In addition, the supporting effect of the mounting member 20 on the carrier 30 can be improved by the transmission assembly 60, so as to improve the stability of the carrier 30 located in the extended position relative to the mounting member 20.

[0066] In some embodiments, see Figure 7 , two transmission assemblies 60 are provided, and the two transmission assemblies 60 are respectively located on both sides of the second enclosure portion 22 along the second direction N. The first drive assembly 40 includes a first output shaft 421 and a second output shaft 422, and the first output shaft 421 and the second output shaft 422 are respectively connected to both sides of the motor 41 along the second direction N. The first output shaft 421 is in transmission cooperation with one transmission assembly 60. The second output shaft 422 is in transmission cooperation with another transmission assembly 60. In this way, the stability of the first drive assembly 40 driving the bearing member 30 to move can be improved. In other embodiments, the first drive assembly 40 can also be provided with a single output shaft 42, and the number of the transmission assembly 60 is one, and the output shaft 42 is in transmission cooperation with the single transmission assembly 60 to realize driving the bearing member 30 to move along the first direction M.

[0067] In some embodiments, see Figure 6 and Figure 7 , the rear assembly 100 also includes a guide rail assembly 50. The guide rail assembly 50 includes a first guide rail 51 and a second guide rail 52. The first guide rail 51 defines a guide groove 513, which extends along the first direction M. The second guide rail 52 defines a mounting groove 523, which extends along the first direction M. The first guide rail 51 is connected to the carrier 30, and the second guide rail 52 is connected to the mounting member 20. The second guide rail 52 is slidably fitted in the guide groove 513 along the first direction M, and the transmission assembly 60 is arranged in the mounting groove 523. The guide rail assembly 50 can improve the reliability of the carrier 30 sliding relative to the mounting member 20 along the first direction M. In addition, accommodating the transmission assembly 60 in the mounting groove 523 can make full use of the internal space of the guide rail assembly 50, thereby improving the space utilization rate of the mounting cavity Q, so that the space of the bearing groove C5 in the carrier 30 is increased, and the loading requirements of target parts 300 of more sizes are met. In this embodiment, two guide rail assemblies 50 are provided and are located on both sides of the second enclosure portion 22 along the second direction N.

[0068] In some embodiments, see Figure 5 , the bearing member 30 also includes a top plate 33. The top plate 33 is connected to the edge of the first enclosure portion 32 away from the first bottom plate 31, and extends to the outside of the first enclosure portion 32. Among them. A receiving cavity (not shown in the figure) is formed between the top plate 33, the first side plate 321 and the fifth side plate 221, and the first drive assembly 40 is accommodated in the receiving cavity. On one side of the bearing member 30 along the width direction Y of the vehicle 200, a first avoidance groove C1 is formed between the top plate 33, the third side plate 323, and the sixth side plate 222, and one of the guide rail assemblies 50 is arranged in the first avoidance groove C1, and the first guide rail 51 of the guide rail assembly 50 is connected to the third side plate 323. On the other side of the carrier 30 along the width direction Y of the vehicle 200, the top plate 33, the fourth side plate 324, and the seventh side plate 223 form a second avoidance groove C2, another guide rail assembly 50 is disposed in the second avoidance groove C2, and the first guide rail 51 of the guide rail assembly 50 is connected to the fourth side plate 324. The first guide rail 51 of the guide rail assembly 50 and the carrier 30 can be connected by various connection methods such as screw connection, pin connection, welding connection or integral molding.

[0069] Through the ingenious design of the structure of the bearing member 30, a receiving cavity is constructed between the bearing member 30 and the mounting member 20 to accommodate the first driving assembly 40, which can improve the structural reliability of the mounting member 20 and the bearing member 30. At the same time, by installing two guide rail assemblies 50 through the first avoidance groove C1 and the second avoidance groove C2, the structural compactness of the rear assembly 100 can be further improved, the space utilization rate can be improved, and the space of the bearing groove C5 can be increased to meet the loading requirements of the target part 300 of larger size.

[0072] The first side wall 512 includes a first connecting section 5121, a second connecting section 5122 and a third connecting section 5123. The first connecting section 5121 is connected to the first bottom wall 511 by bending, and extends in the thickness direction. The second connecting section 5122 is connected to the first connecting section 5121 by bending, and extends toward the second guide rail 52. The third connecting section 5123 is connected to the end of the second connecting section 5122 away from the first connecting section 5121 by bending, and extends toward the first bottom wall 511 in the thickness direction. The first connecting section 5121, the second connecting section 5122 and the third connecting section 5123 together form a first limiting groove C3.

[0073] The second side wall 522 includes a fourth connecting segment 5221, a fifth connecting segment 5222 and a sixth connecting segment 5223.

Among them, the sixth connecting segment 5223 extends into the first limiting groove C3, and the third connecting segment 5123 extends into the second limiting groove C4.

[0074] In some embodiments, see Fig. 9 , the second guide rail 52 is provided with a mounting opening 524.

The threaded portion is also connected to the first bottom wall 511 of the first guide rail 51. In this way, the worm is driven to rotate by the output shaft 42, and the worm drives the worm wheel 621 to rotate, so that the screw 622 can be rotated, and then the threaded portion is driven to move along the first direction M, so as to realize the movement of the first guide rail 51 along the first direction M, and drive the carrier 30 to reciprocate between the storage position and the extended position.

[0076] The cooperation between the worm wheel 621 and the worm has a self-locking property, which can keep the bearing member 30 stably in the storage position and the extended position, thereby ensuring that the bearing member 30 in the extended position can be stably used as a take-off and landing platform of the UAV 301, thereby improving the reliability of use.

[0077] In some embodiments, the first guide rail 51 further includes a mounting portion 514, and a connecting groove C7 is provided on the side of the mounting portion 514 facing away from the opening K along the first direction M, and one end of the screw rod 622 is rotatably engaged in the connecting groove C7. In this way, the mounting portion 514 can not only provide a mounting position for the screw rod 622, but also limit the third transmission member 63, thereby preventing the bearing member 30 from completely falling out of the opening K, and improving the reliability of the rear assembly 100.

[0078] In other embodiments, the first transmission member 61 is two mutually meshing helical gears. The second transmission member 62 includes a screw 622 and a transmission portion. The center line of one helical gear is parallel to the second direction N and is connected to the output shaft 42. The center line of the other helical gear is parallel to the first direction M and is connected to the screw 622.

[0079] In other embodiments, the first transmission member 61 is a gear. The second transmission member 62 is a rack. The third transmission member 63 is a connecting member fixedly connected between the rack and the first guide rail 51. The gear is connected to the output shaft 42. The rack extends along the first direction M and meshes with the gear, and the rack is connected to the carrier 30. Thus, the rack and the carrier 30 can move along the first direction M driven by the gear. The first transmission member 61 can also be constructed as two synchronous wheels spaced apart from each other. One of the synchronous wheels is connected to the output shaft 42. The other synchronous wheel is rotatably connected to the mounting member 20. The second transmission member 62 is a synchronous belt wound around the two synchronous wheels. The synchronous belt is connected to the carrier 30 through the third transmission member 63.

[0080] Therefore, there are many structures for realizing the transmission function of the transmission assembly 60, which will not be described in detail here.

[0081] In some embodiments, see Fig. 9 The mounting plate 84 is provided with a plurality of support portions 85, the support portions 85 are spaced apart from each other along the second direction N, the support portions 85 are provided with support grooves C6, and the support grooves C6 penetrate the support portions 85 along the second direction N. The output shaft 42 is received in the plurality of support grooves C6 and supported by the plurality of support portions 85. In this way, the transmission stability is improved.

[0082] Embodiment 2

[0083] This embodiment provides another rear assembly 100. The difference between the rear assembly 100 of this embodiment and the rear assembly 100 of the first embodiment lies in that the structure of the tailgate 10 is different from that of the first embodiment, and the installation position of the mounting member 20 is different from that of the first embodiment.

[0084] See also Fig.11In some embodiments, the tailgate 10 includes a tailgate body 11 and a cover 13. The tailgate body 11 is provided with an opening 12, and the opening 12 penetrates the tailgate body 11 along the thickness direction of the tailgate body 11. The cover 13 is rotatably connected to the edge of the tailgate body 11 at the opening 12, and the cover 13 is used to open or close the opening 12. The mounting member 20 is fixedly connected to the side of the cover 13 facing the interior space of the vehicle, and the mounting cavity Q is enclosed between the mounting member 20 and the cover 13 (see FIG. Figure 3 ).

[0085] In this way, when the carrier 30 needs to be switched to the extended position, it is only necessary to open the cover member 13 and rotate the cover member 13 relative to the tailgate body 11 until the carrier surface P is roughly perpendicular to the height direction Z of the vehicle 200, without having to open the tailgate 10 of the vehicle 200 relative to the vehicle body 201, thereby improving the loading convenience of the target part 300.

[0086] In some embodiments, the cover 13 is configured as a rear windshield. In other embodiments, the cover 13 may also be configured as a sheet metal structure, which is not specifically limited in this embodiment.

[0087] In some embodiments, see Fig.11 The tailgate 10 further includes a hinge assembly 14. The hinge assembly 14 includes a first hinge 141 and a second hinge 142. The first hinge 141 is connected to an edge of the tailgate body 11 close to the opening 12. The second hinge 142 is connected to an edge of the cover 13. The second hinge 142 is rotatably connected to the first hinge 141. Optionally, the first hinge 141 and the second hinge 142 are both hinges, which are rotatably connected via a hinge shaft (not shown in the figure).

[0088] In some embodiments, there are multiple hinge assemblies 14. The multiple hinge assemblies 14 are spaced apart along the width direction Y of the vehicle 200. For example, in this embodiment, the number of the hinge assemblies 14 can be set to two, three or more.

[0089] In some embodiments, see Fig.11 The rear assembly 100 further includes a second drive assembly 70. One end of the second drive assembly 70 is rotatably connected to the tailgate body 11, and the other end of the second drive assembly 70 is rotatably connected to the cover 13. The second drive assembly 70 is used to drive the cover 13 to rotate relative to the tailgate body 11.

[0090] In some embodiments, see Fig.11The second driving assembly 70 includes a cylinder body 71 and a piston rod 72. One end of the cylinder body 71 is rotatably connected to the tailgate body 11. The piston rod 72 is telescopically connected to the cylinder body 71, and the piston rod 72 is rotatably connected to the cover 13. In addition, the piston rod 72 and the cylinder body 71 can achieve stepless relative movement. When the vehicle 200 is in different parking states (such as when the vehicle 200 is in a non-horizontal parking state), the stroke of the piston rod 72 can be controlled so that the bearing surface P of the bearing member 30 in the extended position is roughly parallel to the horizontal plane, thereby providing a more stable take-off and landing platform for the drone 301.

[0091] In other embodiments, the piston rod 72 may be rotatably connected to the tailgate body 11 , and the cylinder body 71 may be rotatably connected to the cover member 13 . In addition, the second driving assembly 70 may also be configured as a motor 41 .

[0092] In some embodiments, see Fig.11 The tailgate 10 further includes a first connecting block 86 and a second connecting block 87. The first connecting block 86 is fixedly connected to the cover member 13. The second connecting block 87 is fixedly connected to the tailgate body 11. One end of the cylinder 71 is rotatably connected to the second connecting block 87. The free end of the piston rod 72 is rotatably connected to the first connecting block 86.

[0093] In some embodiments, see Fig.11 , the number of the second drive assemblies 70 is two. The two second drive assemblies 70 are spaced apart along the width direction Y of the vehicle 200. One of the second drive assemblies 70 is located on one side of the cover 13 along the width direction Y of the vehicle 200, and the other second drive assembly 70 is located on the other side of the cover 13 along the width direction Y of the vehicle 200. In this way, the rotation reliability and stability of the cover 13 relative to the tailgate body 11 can be improved.

[0094] In some embodiments, see Fig.12 The tailgate 10 further includes a sealing member 81. The sealing member 81 is connected to the tailgate body 11 and is located inside the opening 12. When the cover 13 covers the opening 12 of the tailgate body 11, the cover 13 covers the sealing member 81 to be sealed and connected to the tailgate body 11. The sealing member 81 may be configured as a flexible sealing structure to deform when subjected to pressure from the cover 13, thereby achieving a sealing effect to prevent rainwater or debris from entering the interior space of the vehicle 200 from the opening 12.

[0095] In some embodiments, see Fig.12The tailgate 10 further includes a connecting structure 82. One side of the connecting structure 82 is connected to the tailgate body 11, and the other side of the connecting structure 82 extends into the opening 12. The sealing member 81 is mounted on the connecting structure 82. Both the connecting structure 82 and the sealing member 81 are annular to ensure that reliable sealing effects are obtained at all circumferential locations of the opening 12. The connecting structure 82 can be constructed as a sheet metal structure.

[0096] In some embodiments, see Figure 4 The tailgate 10 further includes a first locking member 151 and a second locking member 152. The first locking member 151 is fixedly connected to the second mounting surface of the cover member 13 and is located at an end of the cover member 13 away from the hinge assembly 14. The second locking member 152 is fixedly connected to the edge of the tailgate body 11 near the opening 12. The first locking member 151 is used to be connected to the second locking member 152 to fix the cover member 13 to the tailgate body 11. In this way, during the driving process of the vehicle 200, the cover member 13 and the tailgate body 11 can remain fixedly connected, thereby ensuring the NVH performance of the vehicle 200. At the same time, under the locking action of the first locking member 151 and the second locking member 152, the cover member 13 can also remain in contact with the sealing member 81, thereby ensuring the sealing performance of the sealing member 81.

[0097] The first locking member 151 and the second locking member 152 can adopt a snap-on locking structure or an electric locking structure, and their specific structures can refer to existing locking structures and will not be described in detail here. The electric locking structure can facilitate the user to remotely control the opening of the cover 13.

[0098] In other embodiments, the number of the first locking members 151 and the number of the second locking members 152 are both plural and the same. The plurality of first locking members 151 are connected to the edge of the cover member 13 along the circumference of the cover member 13. The plurality of second locking members 152 are connected to the tailgate body 11 along the circumference of the opening 12. In this way, the connection reliability between the cover member 13 and the tailgate body 11 can be improved.

[0099] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
