[0049] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] Reference below Figure 1-Figure 9 A lifting assembly 10 according to an embodiment of the present application is described.

[0051] like Figure 1-Figure 9 As shown, a lifting assembly 10 according to an embodiment of the present application is used in a vehicle 100 and includes: a lifting body 1 and a driving mechanism 2 .

[0052] Specifically, refer to Figure 3-Figure 5 and Figure 7 The lifting body 1 includes a first direction (such as Figure 3A plurality of brackets 11 are arranged in a direction a shown in the figure, and a portion of at least one bracket 11 has a curved surface; there are a plurality of driving mechanisms 2, and each bracket 11 can be driven individually by the driving mechanism 2;

[0053] For example, Figure 3-Figure 5 and Figure 7 In the example shown, there are three brackets 11 , but the present application is not limited thereto, and the brackets 11 may also be other numbers, such as 2, 4, 5 or 6.

[0054] Furthermore, if Figure 3-Figure 5 and Figure 7 As shown, the multiple brackets 11 include a first bracket 111 and a second bracket 112. When the lifting assembly 10 rises, the end of the first bracket 111 close to the second bracket 112 rises and moves away from the second bracket 112, and the end of the second bracket 112 close to the first bracket 111 rises; thus, on the one hand, the first bracket 111 and the second bracket 112 can be unfolded when rising, for example, the first bracket 111 and the second bracket 112 are arranged in the first direction, so that the first bracket 111 and the second bracket 112 can be unfolded in the first direction when rising, increasing the support and limiting range of the bracket 11 for the object. On the other hand, when the end of the second bracket 112 close to the first bracket 111 rises, it can avoid interfering with the movement of the first bracket 111.

[0055] When the lifting assembly 10 descends, the end of the first bracket 111 close to the second bracket 112 descends and moves toward the second bracket 112, and the end of the second bracket 112 close to the first bracket 111 descends. Thus, the first bracket 111 and the second bracket 112 can be better stored when descending.

[0056] According to the lifting assembly 10 of the embodiment of the present application, the lifting body 1 includes a plurality of brackets 11 arranged along the first direction of the vehicle 100, each bracket 11 can be driven individually by the driving mechanism 2, and the plurality of brackets 11 include a first bracket 111 and a second bracket 112. When the lifting assembly 10 rises, the end of the first bracket 111 close to the second bracket 112 rises and moves in a direction away from the second bracket 112, and the end of the second bracket 112 close to the first bracket 111 rises; when the lifting assembly 10 descends, the end of the first bracket 111 close to the second bracket 112 descends and moves in a direction close to the second bracket 112, and the end of the second bracket 112 close to the first bracket 111 descends. When each bracket 11 descends, the degree of flushness with the mounting surface 202 can be independently adjusted, so that each bracket 11 can be better flush with the mounting surface 202, thereby improving the flushness between the lifting body 1 and the mounting surface 202, reducing the wind resistance during the driving of the vehicle 100, reducing the energy consumption of the vehicle 100, and reducing wind noise.

[0057] In some embodiments of the present application, Figure 3-Figure 5 and Figure 7 As shown, when the lifting assembly 10 rises, the end of the second bracket 112 close to the first bracket 111 rises and moves in a direction close to the first bracket 111; because when the lifting assembly 10 rises, the end of the first bracket 111 close to the second bracket 112 rises and moves in a direction away from the second bracket 112, so that when the lifting assembly 10 rises, the end of the second bracket 112 close to the first bracket 111 can fill the vacant area after the first bracket 111 moves away from the second bracket 112, so that the first bracket 111 and the second bracket 112 can be spliced ​​together after rising, so that the surfaces of the first bracket 111 and the second bracket 112 at one end facing the rising direction can be flush and spliced ​​after rising.

[0058] Similarly, when the lifting assembly 10 descends, the end of the second bracket 112 close to the first bracket 111 descends and moves in a direction away from the first bracket 111. Since when the lifting assembly 10 descends, the end of the first bracket 111 close to the second bracket 112 descends and moves in a direction close to the second bracket 112, the end of the first bracket 111 close to the second bracket 112 can fill the vacant area generated after the end of the second bracket 112 close to the first bracket 111 moves away from the first bracket 111, so that the first bracket 111 and the second bracket 112 can be spliced ​​together after descending, so that the surfaces of the ends of the first bracket 111 and the second bracket 112 facing the ascending direction can be flush and spliced ​​after descending.

[0059] In some embodiments of the present application, the multiple brackets 11 also include a supplementary bracket. When the lifting assembly 10 rises, the end of the first bracket 111 close to the second bracket 112 rises and moves away from the second bracket 112, the end of the second bracket 112 close to the first bracket 111 rises, and the supplementary bracket rises and is arranged between the first bracket 111 and the second bracket 112. Therefore, by rising the supplementary bracket, the vacant area after the first bracket 111 moves away from the second bracket 112 can be supplemented, so that the first bracket 111 and the second bracket 112 can be spliced ​​together through the supplementary bracket after rising.

[0060] When the lifting assembly 10 descends, the end of the first bracket 111 close to the second bracket 112 descends and moves in the direction close to the second bracket 112, the end of the second bracket 112 close to the first bracket 111 descends, and the supplementary bracket descends and is arranged on the descending side of the first bracket 111 and the second bracket 112. Therefore, through the descent of the supplementary bracket, after the lifting assembly 10 descends, the end of the first bracket 111 close to the second bracket 112 and the end of the second bracket 112 close to the first bracket 111 can be spliced ​​together, so that the surfaces of the first bracket 111 and the second bracket 112 at one end facing the ascending direction can be flush and spliced ​​after descending.

[0061] In some embodiments of the present application, Figure 3-Figure 5 and Figure 7 As shown, when the lifting assembly 10 rises, the end of the first bracket 111 close to the second bracket 112 rises to a height greater than the end of the first bracket 111 away from the second bracket 112 rises, and when the lifting assembly 10 descends, the end of the first bracket 111 close to the second bracket 112 descends to a height greater than the end of the first bracket 111 away from the second bracket 112 descends.

[0062] It can be understood that the surface of the end of the first bracket 111 facing the ascending direction (for example, the upper end in the present application) is a curved surface, which is caused by the difference between the rising height of the end of the first bracket 111 close to the second bracket 112 and the rising height of the end of the first bracket 111 away from the second bracket 112, and the difference between the descending height of the end of the first bracket 111 close to the second bracket 112 and the descending height of the end of the first bracket 111 away from the second bracket 112.

[0063] Thereby, the surfaces at different positions of one end of the first bracket 111 facing the ascending direction can be adjusted to different degrees with the mounting surface 202, so that the movement trajectory of the first bracket 111 at different positions can be adjusted according to the requirement of being flush with the mounting surface 202, thereby further improving the flushness of the lifting body 1 and the mounting surface 202, reducing the wind resistance during the driving of the vehicle 100, reducing the energy consumption of the vehicle 100, and reducing wind noise.

[0064] In some embodiments of the present application, Figure 3 As shown, there are multiple drive mechanisms 2, and each bracket 11 corresponds to each drive mechanism 2. It should be noted that each bracket 11 here refers to each bracket 11 in a lifting body 1, that is, multiple drive mechanisms 2 work independently and are respectively used to drive multiple brackets 11 to rise and fall.

[0065] It can be understood that multiple driving mechanisms 2 are used to independently and correspondingly drive multiple brackets 11 to move, thereby avoiding linkage between the multiple brackets 11, so that each bracket 11 can independently adjust the degree of flushness with the mounting surface 202 when descending, so that each bracket 11 can be better flush with the mounting surface 202, thereby improving the flushness between the lifting body 1 and the mounting surface 202, reducing the wind resistance of the vehicle 100 during driving, reducing the energy consumption of the vehicle 100, and reducing wind noise.

[0066] In some embodiments of the present application, Figure 3-Figure 5 and Figure 7 As shown, multiple brackets 11 are spliced ​​in sequence along the first direction. It should be noted that the splicing of multiple brackets 11 in sequence along the first direction does not mean that the multiple brackets 11 are connected to each other, but that the surfaces of the multiple brackets 11 facing each other fit each other. For example, if the end face of a bracket 11 facing an adjacent bracket 11 is an inclined surface, then the end face of the adjacent bracket 11 facing it is also a matching inclined surface. At the same time, the splicing of multiple brackets 11 in sequence along the first direction refers to the state in which multiple brackets 11 are spliced ​​in sequence along the first direction after the lifting body 1 has completed its ascent or descent.

[0067] It is understandable that the multiple brackets 11 are spliced ​​in sequence along the first direction, which can further avoid mutual interference between the multiple brackets 11, so that the multiple brackets 11 can be lifted and lowered smoothly and reliably. On the other hand, the multiple brackets 11 are spliced ​​in sequence along the first direction, so that the multiple brackets 11 fit each other, reduce the gaps between the multiple brackets 11, and thus make the structure more compact.

[0068] In some embodiments of the present application, Figure 3-Figure 5 and Figure 7 As shown, the first bracket 111 is movable in the lifting direction and in the first direction, and the second bracket 112 is movable in the lifting direction. At the same time, one end of the second bracket 112 close to the first bracket 111 is movable in the first direction.

[0069] It can be understood that, since the first bracket 111 and the second bracket 112 can move in the lifting direction of the vehicle 100 and the first direction, the spatial adjustment dimension of the first bracket 111 and the second bracket 112 is increased, and the flushness between the lifting body 1 and the mounting surface 202 is further increased. At the same time, since the ends of the first bracket 111 and the second bracket 112 close to the first bracket 111 can move in the lifting direction of the vehicle 100 and the first direction, the movement interference between the first bracket 111 and the second bracket 112 can be avoided during adjustment.

[0070] Below Figure 3-Figure 5 and Figure 7Take the following as an example to illustrate the movement of the first bracket 111 and the second bracket 112 during the ascending and descending processes:

[0071] When the lifting assembly is rising, the first bracket 111 rises first, and at the same time moves along the first direction toward and away from the second bracket 112, leaving space for the movement of the second bracket 112. After the first bracket 111 has finished rising, the second bracket 112 rises again. At the same time, the end of the second bracket 112 close to the first bracket 111 moves toward the first bracket 111. In this way, interference between the first bracket 111 and the second bracket 112 during the rising process can be avoided, ensuring a smooth rising process.

[0072] When the lifting assembly is descending, the second bracket 112 descends first, and at the same time, the end of the second bracket 112 close to the first bracket 111 moves along the first direction toward the direction away from the first bracket 111, leaving space for the movement of the first bracket 111. After the second bracket 112 has been completely descended, the first bracket 111 descends again and moves toward the second bracket 112. In this way, interference between the first bracket 111 and the second bracket 112 during the descent process can be avoided, thereby ensuring a smooth descent process.

[0073] In summary, by enabling the first bracket 111 and the second bracket 112 to move at one end close to the first bracket 111 in the lifting direction and the first direction of the vehicle 100, interference between the first bracket 111 and the second bracket 112 during the rising and falling process can be avoided, thereby ensuring a smooth rising and falling process.

[0074] In other embodiments of the present application, the first bracket 111 is movable along the lifting direction and can rotate around one of the ends of the first bracket 111, and the second bracket 112 is movable along the lifting direction and can rotate around one of the ends of the second bracket 112. The plurality of driving mechanisms 2 work independently and are used to drive the first bracket 111 and the second bracket 112 to move, respectively, so that each bracket 11 can independently adjust the motion trajectory according to different requirements for being flush with the installation surface 202, thereby improving the flushness of the lifting body 1 and the installation surface 202.

[0075] In some embodiments of the present application, Figure 3-Figure 9 As shown, multiple driving mechanisms 2 include a first driving mechanism 21, which is used to drive the first bracket 111 to move. The first driving mechanism 21 includes: a first connecting rod 211, a second connecting rod 212 and a first driving motor 214. The lower ends of the first connecting rod 211 and the second connecting rod 212 are both rotatably connected to the vehicle 100, and the ends of the first connecting rod 211 and the second connecting rod 212 facing the upward direction are both rotatably connected to the first bracket 111; the first driving motor 214 is used to drive at least one of the first connecting rod 211 and the second connecting rod 212 to rotate.

[0076] It should be noted that the ends of the first connecting rod 211 and the second connecting rod 212 facing the upward direction are both connected to the first bracket 111 through a hinge, so that the ends of the first connecting rod 211 and the second connecting rod 212 facing the upward direction are both rotatably connected to the first bracket 111; similarly, the lower ends of the first connecting rod 211 and the second connecting rod 212 are both rotatably connected to the vehicle 100 through a hinge. The first drive motor 214 transmits power to at least one of the first connecting rod 211 and the second connecting rod 212 through a transmission shaft. For example, in the present application, the first drive motor 214 drives the second connecting rod 212 to rotate, but the present application is not limited thereto. The first drive motor 214 may also drive the first connecting rod 211 to rotate, or the first drive motor 214 may simultaneously drive the first connecting rod 211 and the second connecting rod 212 to rotate.

[0077] It can be understood that, through the above-mentioned setting method, the rotation of the first connecting rod 211 and the second connecting rod 212 can be converted into the movement of the first bracket 111 in the first direction and the lifting direction of the vehicle 100, thereby increasing the spatial adjustment dimension of the first bracket 111 and further increasing the flushness of the lifting body 1 and the mounting surface 202.

[0078] For example, Figure 6 , Figure 8 and Fig. 9 In the example shown, as viewed from the inside of the paper, the first connecting rod 211 and the second connecting rod 212 rotate clockwise to move the first bracket 111 backward and downward, thereby lowering the first bracket 111. The first connecting rod 211 and the second connecting rod 212 rotate counterclockwise to move the first bracket 111 forward and upward, thereby raising the first bracket 111.

[0079] In some other embodiments of the present application, the first driving mechanism 21 may also include a five-bar mechanism, which drives the first bracket 111 to move in the lifting direction and the first direction through the five-bar mechanism; the first driving mechanism 21 may also include a guide groove and a guide block, the guide groove is arranged on the vehicle 100, and the guide block is movably arranged in the guide groove along the length direction of the guide groove. The extension direction of the guide groove is designed according to the movement trajectory of the first bracket 111 in the lifting direction and the first direction. The guide block is arranged on the first bracket 111 and connected to the first bracket 111, and the guide block is driven by the first driving motor 214 to drive the first bracket 111 to move in the lifting direction and the first direction.

[0080] In some embodiments of the present application, Figure 3-Figure 9As shown, the first bracket 111 includes a first sub-frame 1111 and a second sub-frame 1112 arranged along a first direction of the vehicle 100, the first sub-frame 1111 is located on a side of the second sub-frame 1112 away from the second bracket 112, and the first sub-frame 1111 and the second sub-frame 1112 are rotatably connected at one end facing the rising direction near each other. It should be noted that the first sub-frame 1111 and the second sub-frame 1112 are rotatably connected at one end facing the rising direction near each other by a hinge.

[0081] It can be understood that, through the mutual rotation between the first sub-frame 1111 and the second sub-frame 1112, the first bracket 111 can be further adjusted, so that the first bracket 111 can be better adjusted to be flush with the mounting surface 202, so that the first bracket 111 can be better flush with the mounting surface 202, thereby further improving the flushness between the lifting body 1 and the mounting surface 202, reducing the wind resistance during the driving of the vehicle 100, and reducing the energy consumption of the vehicle 100.

[0082] In some embodiments of the present application, Figure 6 , Figure 8 and Fig. 9 As shown, the first connecting rod 211 is located on the side of the second connecting rod 212 away from the second bracket 112, and the first driving mechanism 21 further includes: a third connecting rod 213, one end of the third connecting rod 213 is rotatably connected to the second sub-frame 1112 and one end of the second connecting rod 212 facing the ascending direction, and the other end of the third connecting rod 213 is rotatably connected to the first sub-frame 111 and one end of the first connecting rod 211 facing the ascending direction. It should be noted that the third connecting rod 213 is rotatably connected to the first sub-frame 1111 and the second sub-frame 1112 via a hinge.

[0083] It is understandable that the first connecting rod 211, the second connecting rod 212 and the third connecting rod 213 form a four-bar structure, which usually has one degree of freedom, that is, only one independent motion mode, which makes its motion trajectory controllable and stable. By designing the length of the rod and the hinge position, a specific motion trajectory and angle change can be achieved. The four-bar structure has good mechanical properties, can withstand large loads, and remains stable during movement. By adjusting the length of the rod and the hinge position, it can adapt to different application requirements, such as achieving linear motion, curved motion or rotation at a specific angle.

[0084] Furthermore, if Figure 6 , Figure 8 and Fig. 9As shown, the third connecting rod 213 is provided with a slide slot 215 extending along the first direction of the third connecting rod 213, and the second sub-frame 1112 is provided with a pin shaft 216, and the pin shaft 216 is movably arranged in the slide slot 215. Thus, the third connecting rod 213 and the second sub-frame 1112 can be limited, so as to avoid the third connecting rod 213 and the second sub-frame 1112 from being separated, so that the structure is reliable and stable; at the same time, through the limit of the movement range of the pin shaft 216 by the slide slot 215, the movement trajectory of the second sub-frame 1112 can be limited, so as to avoid the movement of the second sub-frame 1112 beyond the preset range, thereby ensuring that the first bracket 111 and the second sub-frame 1112 can be better flush with the mounting surface 202.

[0085] In some embodiments of the present application, Figure 6 , Figure 8 and Fig. 9 As shown, when the first bracket 111 rises, the angle between the ends of the first sub-frame 1111 and the second sub-frame 1112 close to each other is A, and when the first bracket 111 descends, the angle between the ends of the first sub-frame 1111 and the second sub-frame 1112 close to each other is B, and satisfies: B>A.

[0086] It can be understood that when the first bracket 111 rises, the angle between the ends of the first sub-frame 1111 and the second sub-frame 1112 close to each other is smaller, thereby making the structure between the first sub-frame 1111 and the second sub-frame 1112 compact, and when the first bracket 111 descends, the angle between the ends of the first sub-frame 1111 and the second sub-frame 1112 close to each other becomes larger, thereby through the change of the angle between the ends of the first sub-frame 1111 and the second sub-frame 1112 close to each other, the first sub-frame 1111 and the second sub-frame 1112 can be flush with the mounting surface 202.

[0087] Reference below Figure 6 , Figure 8 and Fig. 9 The example shown is used to describe the movement of the first sub-rack 1111 and the second sub-rack 1112 when descending:

[0088] When the first bracket 111 is descending, the angle between the ends of the first sub-frame 1111 and the second sub-frame 1112 close to each other remains unchanged at first. When the second sub-frame 1112 is descended into place, the descending and backward movement of the second sub-frame 1112 is blocked, so that the front end of the first sub-frame 1111 rises, thereby increasing the angle between the ends of the first sub-frame 1111 and the second sub-frame 1112 close to each other.

[0089] In some embodiments of the present application, Figure 3-Figure 5 and Figure 7As shown, when the first bracket 111 is raised, the first sub-rack 1111 and the second sub-rack 1112 are close to each other at one end. Therefore, when the first bracket 111 is raised, the compact structure can be maintained, and the first bracket 111 is prevented from occupying too much movement space of the second bracket 112, and the movement interference between the first bracket 111 and the second bracket 112 is further reduced.

[0090] In some embodiments of the present application, Figure 6 , Figure 8 and Fig. 9 As shown, the lifting assembly 10 further includes: a limiting column 3, the limiting column 3 is arranged on the mounting surface 202 of the lifting assembly 10, and when the first bracket 111 is descending, one end of the limiting column 3 facing the ascending direction abuts against the first sub-frame 1111. It can be understood that when the first bracket 111 is descending, the one end of the limiting column 3 facing the ascending direction abuts against the first sub-frame 1111, so that the contact point between the limiting column 3 and the first sub-frame 1111 becomes a fulcrum, so that the first sub-frame 1111 can rotate relative to the contact point between the limiting column 3 and the first sub-frame 1111, so that when the first bracket 111 is descending, the angle between the ends of the first sub-frame 1111 and the second sub-frame 1112 close to each other changes, so that the first sub-frame 1111 and the second sub-frame 1112 can better adjust the flatness with the mounting surface 202.

[0091] Reference below Figure 6 , Figure 8 and Fig. 9 The example shown is used to describe the movement of the first sub-rack 1111 and the second sub-rack 1112 when descending:

[0092] When the first bracket 111 descends, the angle between the ends of the first sub-frame 1111 and the second sub-frame 1112 close to each other remains unchanged at the beginning. When the second sub-frame 1112 descends into place, the descending and backward movement of the second sub-frame 1112 is blocked, and at the same time, the first sub-frame 1111 stops at one end of the limiting column 3 facing the ascending direction, so that the first sub-frame 1111 rotates, thereby increasing the angle between the ends of the first sub-frame 1111 and the second sub-frame 1112 close to each other.

[0093] In some embodiments of the present application, Figure 3-Figure 5 and Figure 7 As shown, the second bracket 112 includes: a third sub-frame 1121 and a fourth sub-frame 1122. When the second bracket 112 is rising, at least parts of the third sub-frame 1121 and the fourth sub-frame 1122 are arranged along the first direction, and the third sub-frame 1121 is located on a side of the fourth sub-frame 1122 close to the first bracket 111. When the second bracket 112 is descending, the third sub-frame 1121 is located above the fourth sub-frame 1122.

[0094] It can be understood that when the third sub-frame 1121 and the fourth sub-frame 1122 move relative to each other along the first direction of the vehicle 100 from the raised state of the second bracket 112, since the third sub-frame 1121 is located above the fourth sub-frame 1122, movement interference between the third sub-frame 1121 and the fourth sub-frame 1122 can be avoided.

[0095] For example, Figure 3-Figure 5 and Figure 7 In the example shown, from the raised state to the lowered state of the second bracket 112, the third sub-frame 1121 and the fourth sub-frame 1122 descend, and the moving distance of the fourth sub-frame 1122 is greater than the moving distance of the third sub-frame 1121. At the same time, the third sub-frame 1121 also needs to move along the first direction. Since the fourth sub-frame 1122 is located below the third sub-frame 1121 at this time, it will not affect the movement of the third sub-frame 1121.

[0096] In some embodiments of the present application, Figure 3-Figure 5 and Figure 7 As shown, the multiple driving mechanisms 2 include a second driving mechanism 22, and the second driving mechanism 22 is used to drive the fourth sub-frame 1122 to rise and fall. The third sub-frame 1121 is linked with the fourth sub-frame 1122. When the fourth sub-frame 1122 rises, the third sub-frame 1121 moves toward the first bracket 111 and rises, and when the fourth sub-frame 1122 descends, the third sub-frame 1121 moves in a direction away from the first bracket 111 and descends.

[0097] It can be understood that when the second bracket 112 is in the descending state, the third sub-frame 1121 and the fourth sub-frame 1122 are both descended, and the descending distance of the third sub-frame 1121 is less than the descending distance of the fourth sub-frame 1122. At the same time, the third sub-frame 1121 moves in the direction away from the first bracket 111. Since the third sub-frame 1121 is located above the fourth sub-frame 1122 at this time, there is no motion interference between the third sub-frame 1121 and the fourth bracket 11. At the same time, the length of the lifting body 1 along the first direction of the vehicle 100 can be reduced during the descending process, saving storage space.

[0098] When the second bracket 112 rises, the third sub-rack 1121 and the fourth sub-rack 1122 both rise, and the rising distance of the third sub-rack 1121 is smaller than the rising distance of the fourth sub-rack 1122. At the same time, the third sub-rack 1121 moves toward the direction close to the first bracket 111, thereby providing space for the fourth sub-rack 1122 to rise, avoiding movement interference between the third sub-rack 1121 and the fourth sub-rack 1122.

[0099] In some embodiments of the present application, Figure 3-Figure 5 and Figure 7As shown, the second driving mechanism 22 includes: a second driving motor 221, a gear 222 and a rack 223, the second driving motor 221 is arranged on the vehicle 100; the gear 222 is connected to the output shaft of the second driving motor 221; the rack 223 is arranged on the fourth sub-frame 1122 and extends along the lifting direction, and the rack 223 cooperates with the gear 222.

[0100] It can be understood that the output shaft of the second drive motor 221 is connected to the transmission shaft, and the end of the transmission shaft away from the second drive motor 221 is connected to the gear 222, thereby driving the gear 222 to rotate, and the gear 222 moves up and down relative to the rack 223 on the rack 223, so that the fourth sub-frame 1122 can be driven to rise, thereby realizing the second drive mechanism 22 driving the fourth sub-frame 1122 to rise.

[0101] In some other embodiments of the present application, the second driving mechanism 22 may further include a screw rod, which is driven to rotate by the second driving motor 221, and the screw rod cooperates with a threaded structure provided on the fourth sub-frame 1122 to drive the fourth sub-frame 1122 to rise and fall.

[0102] In some embodiments of the present application, Figure 3-Figure 5 and Figure 7 As shown, the fourth sub-frame 1122 has a guide rail 1123, and in the direction of self-descent, the guide rail 1123 is inclined toward the first bracket 111, and the third sub-frame 1121 has a guide portion 1124 slidably connected to the guide rail 1123. In this way, the third sub-frame 1121 cooperates with the fourth sub-frame 1122 and is configured to move and rise toward the first bracket 111 when the fourth sub-frame 1122 rises, and to move and fall in a direction away from the first bracket 111 when the fourth sub-frame 1122 falls. Through the movement trajectory of the third sub-frame 1121 and the fourth sub-frame 1122, the third sub-frame 1121 and the fourth sub-frame 1122 can be better aligned with the installation surface 202, thereby improving the alignment of the lifting body 1 and the installation surface 202, reducing the wind resistance during the driving of the vehicle 100, and reducing the energy consumption of the vehicle 100.

[0103] Specifically, the fourth sub-frame 1122 is a trapezoidal structure, and the length of one end surface of the fourth sub-frame 1122 facing the ascending direction in the first direction is less than the length of the end surface of the fourth sub-frame 1122 facing the descending direction in the first direction. The guide rails 1123 are arranged along both sides of the trapezoidal structure so that the guide rails 1123 are inclined toward the first bracket 111. The guide portion 1124 is a rod-shaped structure, one end of the guide portion 1124 is connected to the third sub-frame 1121, and the other end is slidably connected to the guide rail 1123. In the self-descending direction, the guide portion 1124 is inclined toward the fourth sub-frame 1122. By setting the inclination direction of the guide part 1124 and the guide rail 1123, when the second driving mechanism 22 drives the fourth sub-frame 1122 to descend, the component force of the movement drives the third sub-frame 1121 to descend while moving in the direction away from the first bracket 111, and the distance the third sub-frame 1121 descends is smaller than the fourth sub-frame 1122; when the second driving mechanism 22 drives the fourth sub-frame 1122 to rise, the component force of the movement drives the third sub-frame 1121 to rise while moving in the direction of the first bracket 111, and the distance the third sub-frame 1121 rises is smaller than the fourth sub-frame 1122. Through the movement trajectories of the third sub-frame 1121 and the fourth sub-frame 1122, the third sub-frame 1121 and the fourth sub-frame 1122 can be made to be better flush with the installation surface 202, thereby improving the flushness between the lifting body 1 and the installation surface 202, reducing the wind resistance during the driving of the vehicle 100, and reducing the energy consumption of the vehicle 100. The cross-section of the end portion where the guide portion 1124 and the guide rail 1123 are slidably connected is a dovetail groove, and a T-block structure extending into the dovetail groove is provided at the matching position between the guide rail 1123 and the guide portion 1124, which can improve the stability of the sliding connection between the guide portion 1124 and the guide rail 1123.

[0104] In some embodiments of the present application, Figure 3-Figure 5 and Figure 7 As shown, there are two first brackets 111, which are respectively arranged on both sides of the second bracket 112 along the first direction, and there are two third sub-racks 1121, which are respectively arranged on both sides of the fourth sub-rack 1122 along the first direction of the vehicle 100.

[0105] Among them, it should be noted that the fourth sub-frame 1122 has two guide rails 1123, and the two guide rails 1123 are respectively arranged on the front and rear sides of the fourth sub-frame 1122. In the self-descending direction, the guide rails 1123 are inclined toward the first bracket 111, and the third sub-frame 1121 has a guide part 1124 that cooperates with the guide rails 1123, and the guide parts 1124 are two corresponding to the two guide rails 1123 one by one.

[0106] It can be understood that when the lifting body 1 is in the descending state, the two third sub-frames 1121 and the fourth sub-frame 1122 both descend, and the descending distance of the third sub-frame 1121 is less than the descending distance of the fourth sub-frame 1122. At the same time, the two third sub-frames 1121 move in the direction away from the first bracket 111 to provide space for the movement of the two first brackets 111. When the two third sub-frames 1121 and the fourth sub-frame 1122 are both descended into place, the two first brackets 111 move toward the third sub-frame 1121 and descend, thereby realizing the descent of the two first brackets 111, thereby realizing the descent of the lifting body 1.

[0107] When the lifting body 1 is rising, the two first brackets 111 rise first and move in a direction away from the third sub-frame 1121 to provide space for the movement of the third sub-frame 1121. Then the two third sub-frames 1121 and the fourth sub-frame 1122 all rise, and the rising distance of the two third sub-frames 1121 is less than the rising distance of the fourth sub-frame 1122. At the same time, the two third sub-frames 1121 move in a direction close to the first bracket 111, thereby providing space for the fourth sub-frame 1122 to rise, thereby realizing the rising of the second bracket 112 and the rising of the lifting body 1.

[0108] In some embodiments of the present application, Figure 3-Figure 5 and Figure 7 As shown, when the lifting assembly 10 rises, the second driving mechanism 22 drives the two third sub-frames 1121 to move away from each other; when the lifting assembly 10 descends, the second driving mechanism 22 drives the two third sub-frames 1121 to move toward each other.

[0109] It can be understood that when the lifting body 1 is in the descending state, the two third sub-frames 1121 and the fourth sub-frame 1122 both descend, and the descending distance of the third sub-frame 1121 is less than the descending distance of the fourth sub-frame 1122. At the same time, the second driving mechanism 22 drives the two third sub-frames 1121 to move in the direction of approaching each other, that is, the two third sub-frames 1121 move in the direction away from the first bracket 111, providing space for the movement of the two first brackets 111. When the two third sub-frames 1121 and the fourth sub-frame 1122 are both descended into place, the two first brackets 111 move toward the third sub-frame 1121 and descend, thereby realizing the descent of the two first brackets 111, thereby realizing the descent of the lifting body 1.

[0110] When the lifting body 1 is rising, the two first brackets 111 rise first and move in a direction away from the third sub-frame 1121 at the same time, providing space for the movement of the third sub-frame 1121, and then the two third sub-frames 1121 and the fourth sub-frame 1122 all rise, and the rising distance of the two third sub-frames 1121 is less than the rising distance of the fourth sub-frame 1122. At the same time, the second driving mechanism 22 drives the two third sub-frames 1121 to move in directions away from each other, that is, the two third sub-frames 1121 move in a direction close to the first bracket 111, thereby providing space for the fourth sub-frame 1122 to rise, realizing the rising of the second bracket 112, and thus realizing the rising of the lifting body 1.

[0111] In some embodiments of the present application, Figure 3-Figure 5 and Figure 7 As shown, the end of the first bracket 111 away from the second bracket 112 along the first direction has a curved surface, and the second bracket 112 extends straight along the first direction. The end of the first bracket 111 is a curved surface, and the second bracket 112 is a straight line, which can improve the aesthetics of the shape. Through multiple driving mechanisms 2 working independently and respectively driving the first bracket 111 and the second bracket 112 to move, the first bracket 111 with a curved surface shape and the second bracket 112 with a straight line shape can be better aligned with the installation surface 202, thereby improving the alignment of the lifting body 1 and the installation surface 202, reducing the wind resistance during the driving process of the vehicle 100, and reducing the energy consumption of the vehicle 100.

[0112] Of course, the shapes of the first bracket 111 and the second bracket 112 can also be adjusted according to the design, and multiple driving mechanisms 2 can also drive the first bracket 111 and the second bracket 112 to move respectively to achieve the flushness of the first bracket 111 and the second bracket 112 with the installation surface 202.

[0113] In some embodiments of the present application, Figure 1-Figure 3 As shown, the lifting body 1 is moved along the second direction (such as Figure 3 The two lifting bodies 1 are arranged relatively to each other in the direction b shown in the figure. The brackets 11 arranged relatively to each other in the second direction of the two lifting bodies 1 are driven by the same driving mechanism 2. The first direction, the second direction and the lifting direction are perpendicular to each other. It can be understood that the arrangement of the two lifting bodies 1 allows the luggage to be placed on the lifting bodies 1 more stably and reliably. At the same time, the brackets 11 arranged relatively to each other in the second direction of the two lifting bodies 1 are driven by the same driving mechanism 2, thereby reducing the number of driving mechanisms 2. In addition, the brackets 11 arranged relatively to each other in the second direction of the two lifting bodies 1 can also be kept synchronous when they are lifted and lowered, so that the installation surface 202 is smoother.

[0114] In some embodiments of the present application, Figure 1As shown, the lifting assembly 10 is a luggage rack assembly. In other embodiments of the present application, the lifting assembly 10 can also be a vehicle body trim, a deflector, etc.

[0115] Reference below Figure 1-Figure 2 A vehicle 100 according to an embodiment of the present application is described.

[0116] like Figure 1 and Figure 2 As shown, the vehicle 100 according to the embodiment of the present application includes: a vehicle body 20 and the above-mentioned lifting assembly 10, the driving mechanism 2 is arranged on the vehicle body 20, and the lifting body 1 is liftably arranged on the top of the vehicle body 20.

[0117] It is understandable that when the lifting body 1 is not needed, it can be lowered to reduce the overall wind resistance coefficient of the vehicle 100. After the wind resistance coefficient is reduced, the air resistance encountered by the vehicle 100 during driving is reduced, and the engine does not need to output too much power to overcome the resistance, thereby reducing fuel consumption and achieving the purpose of saving fuel. At the same time, the lowered lifting body 1 reduces the overall height and center of gravity of the vehicle 100. The lower center of gravity can make the vehicle 100 more stable during driving, especially when driving at high speed, turning or encountering severe weather conditions such as strong winds, which can effectively reduce the risk of the vehicle 100 rolling over or losing control, and improve driving safety. In addition, lowering the lifting body 1 can reduce the impact of natural factors such as wind, sun, and rain on it, reduce the aging, rust and corrosion rate of the surface coating of the lifting body 1, and extend the service life of the lifting body 1.

[0118] According to the vehicle 100 of the embodiment of the present application, the lifting assembly 10 is provided, and the lifting body 1 includes a plurality of brackets 11 arranged along the first direction of the vehicle 100, each bracket 11 can be driven individually by the driving mechanism 2, and the plurality of brackets 11 include a first bracket 111 and a second bracket 112. When the lifting assembly 10 rises, the end of the first bracket 111 close to the second bracket 112 rises and moves in a direction away from the second bracket 112, and the end of the second bracket 112 close to the first bracket 111 rises; when the lifting assembly 10 descends, the end of the first bracket 111 close to the second bracket 112 descends and moves in a direction close to the second bracket 112, and the end of the second bracket 112 close to the first bracket 111 descends. When each bracket 11 descends, the degree of flushness with the mounting surface 202 can be independently adjusted, so that each bracket 11 can be better flush with the mounting surface 202, thereby improving the flushness between the lifting body 1 and the mounting surface 202, reducing the wind resistance during the driving process of the vehicle 100, reducing the energy consumption of the vehicle 100, and reducing wind noise.

[0119] In some embodiments of the present application, Figure 1 and Figure 2As shown, a receiving groove 201 is provided on the top of the vehicle body 20. When the lifting body 1 is lowered, at least part of it is located in the receiving groove 201. When the lifting body 1 is raised, at least part of it is located above the vehicle body 20. As a result, the lifting body 1 can be better hidden when not in use, thereby further reducing the influence of natural factors such as wind, sun, and rain on it, reducing the aging, rusting and corrosion rate of the surface coating of the lifting body 1, and extending the service life of the lifting body 1.

[0120] The receiving groove 201 extends along the first direction, so as to better conform to the shape of the lifting body 1 and better accommodate and hide the lifting body 1 .
