Referring to fig. 1 and 2, an automobile according to an embodiment of the present application includes a tail assembly 300 and a body, wherein the tail assembly 300 is disposed on the body. Specifically, the tail assembly 300 may be mounted at the rear of the vehicle body to reduce the lift at the rear of the vehicle and improve the stability of the vehicle during high-speed driving. Illustratively, the tail assembly 300 may be mounted to the rear trunk area of the vehicle body to be stably carried on the vehicle body while providing a relatively aesthetic overall appearance to the vehicle.

Referring to fig. 3 to 6, a tail assembly 300 according to an embodiment of the present application includes a tail structure 100 and a penetrating lamp structure 200. The tail structure 100 comprises a tail outer panel 10, a movement assembly 30, a drive assembly 40 and a tail base 20. The driving assembly 40 is used for driving the movement assembly 30 to move so as to drive the tail outer panel 10 to move relative to the tail base 20. Is fixedly mounted to the tail base 20 throughout the lamp structure 200.

In the tail assembly 300 and the automobile according to the embodiments of the present application, the driving assembly 40 is used for driving the movement assembly 30 to move, so as to drive the tail outer plate 10 to move relative to the tail base 20, so that the lift force of the automobile can be reduced, the stability of the automobile during high-speed running can be improved, and the wind resistance of the automobile during high-speed running can be reduced. In addition, the penetrating lamp structure 200 is fixedly mounted on the tail base 20, so that the tail structure 100 and the penetrating lamp structure 200 are integrated integrally, the mounting process can be simplified, and the two are matched with each other more robustly.

Specifically, the driving assembly 40 is used for driving the movement assembly 30 to move, so as to drive the tail outer panel 10 to move relative to the tail base 20. The tail base 20 may be mounted on the vehicle body, and when the driving assembly 40 drives the moving assembly 30 to move, the tail base 20 is fixed relative to the vehicle body, and the tail outer panel 10 moves relative to the tail base 20, such as a turning motion and/or a lifting motion, so as to achieve various effects of changing the air flow direction around the vehicle, reducing the resistance of the vehicle, and enhancing the grip between the wheels and the ground.

In one embodiment, the tailplane outer plate 10 may have a retracted state (as shown in fig. 3 and 4) and a raised state (as shown in fig. 5 and 6), and may be switchable between the two states according to the vehicle speed. When the automobile runs at a high speed, the driving assembly 40 can drive the movement assembly 30 to move so as to drive the tail outer plate 10 to perform overturning movement relative to the tail base 20, and then perform lifting movement (specifically lifting movement) so as to reach a lifting state, thereby playing a role in reducing wind resistance of the automobile running at a high speed, further reducing energy consumption of the automobile and improving mileage. When the automobile runs at a low speed or stops running, the driving assembly 40 can drive the movement assembly 30 to move so as to drive the tail outer plate 10 to perform lifting movement (specifically, descending movement) relative to the tail base 20, and then perform overturning movement so as to reach a retracted state, so that the whole surface of the tail shell of the automobile is streamline, and the whole shape of the automobile is not changed.

In other embodiments, the tail outer panel 10 may be adjusted according to other conditions, such as vehicle conditions, road conditions, environmental conditions, etc., without limitation. In addition, the state of the tail outer panel 10 is not limited thereto, and the tail outer panel 10 may have a third state between the retracted state and the raised state, etc. according to actual needs, so as to be positioned at an appropriate height and angle with respect to the tail base 20 for optimum aerodynamic performance.

According to the embodiment of the application, the driving assembly 40 drives the movement assembly 30 to move so as to drive the tail outer plate 10 to move relative to the tail base 20, and the conventional fixed tail is designed as the active lifting tail, so that the lift force of an automobile can be reduced, the stability of the automobile during high-speed running can be improved, meanwhile, the wind resistance of the automobile during high-speed running can be reduced, the aerodynamic performance can be optimized, and the arrangement and structural design space of the tail structure 100 can be ensured to the greatest extent.

Is fixedly mounted to the tail base 20 throughout the lamp structure 200. For example, the penetrating lamp structure 200 and the tail base 20 may be assembled together by fastening, gluing, bolting, ultrasonic welding, laser welding, etc., which is not limited herein.

According to the embodiment of the application, the penetrating lamp structure 200 is fixedly arranged on the tail base 20, so that the tail structure 100 and the penetrating lamp structure 200 are integrated integrally, the installation procedure can be simplified, and the two are matched more robustly. The tail structure 100 and the through-lamp structure 200 may be mounted as a large assembly (i.e. the tail assembly 300) to other components of the vehicle, such as the tail gate sheet metal. Compared with the existing installation sequence, the method has the advantages that the sequential installation sequence and the installation direction between the tail wing structure 100 and the penetrating lamp structure 200 are not needed to be considered, the tail wing structure 100 and the penetrating lamp structure 200 are directly assembled together, the influence of the dimensional chain tolerance of a vehicle body is avoided, the gap matching requirement between the tail wing structure 100 and the penetrating lamp structure 200 can be ensured, and the installation accuracy is high.

Referring to fig. 2 and 7, in some embodiments, the flight base 20 includes a flight bottom plate 21 and a flight side plate 23. The tail side plates 23 are arranged on the tail bottom plate 21 at an included angle. And is fixedly connected with the tail side plate 23 through the lamp structure 200.

In particular, the tailplane 21 may be used to mount or carry the movement assembly 30, the drive assembly 40, etc. The tail side plate 23 extends from the end of the tail bottom plate 21 toward the tail outer plate 10. The tailplane side plates 23 form an angle with the tailplane bottom plate 21, and the whole is generally formed into an "L" structure (as shown in fig. 7) to facilitate assembly with the tailplane side plates 23 throughout the lamp structure 200. Since the penetrating lamp structure 200 is assembled on the side surface of the tail base 20, the space on the side surface of the tail base 20 can be fully utilized, not only the disassembly and the installation are convenient, but also the structural arrangement design is facilitated, and the volume of the tail structure 100 and the penetrating lamp structure 200 after being assembled together is reduced.

Further, the angle between the tail side plate 23 and the tail bottom plate 21 is an acute angle. For example, the angle between the tailplane side plate 23 and the tailplane bottom plate 21 ranges from (30 °,80 °). Because the included angle between the tail side plate 23 and the tail bottom plate 21 is an acute angle, when the tail outer plate 10 is covered on the tail base 20, the installation space formed between the tail outer plate 10 and the tail side plate 23 is larger, and the penetrating lamp structure 200 is more convenient to install.

With continued reference to fig. 2 and 7, in some embodiments, the tail side plate 23 is provided with a first mounting member 231 and a second mounting member 201 is provided through the lamp structure 200. The first mounting member 231 cooperates with the second mounting member 201 to fixedly connect the tail side plate 23 with the through-lamp structure 200.

Specifically, the first and second mounting members 231 and 201 may function as a positioning and fixing mount. By the positional engagement of the first mounting member 231 and the second mounting member 201, dislocation of the tail side plate 23 and the through-lamp structure 200 during mounting can be avoided, and the mounting accuracy can be improved. In addition, by the structural cooperation of the first mounting member 231 and the second mounting member 201, the rear wing side plate 23 can be prevented from being displaced after being mounted with the penetrating lamp structure 200, and the reliability of the structure can be improved.

Illustratively, the first mount 231 may be a mounting hole and the second mount 201 may be a mounting post; alternatively, the first mounting member 231 is a mounting post and the second mounting member 201 is a mounting hole; alternatively, part of the first mounting members 231 are mounting holes, part of the first mounting members 231 are mounting posts, part of the second mounting members 201 corresponding to the part of the first mounting members 231 are mounting posts, and part of the second mounting members 201 are mounting holes. The specific form of the mounting post may be a bolt, a stud, a screw, or a raised structure on the surface of the element, etc., and is not limited herein. In addition, nuts and the like may be disposed at the mounting holes as needed.

Further, referring to fig. 8, the number of the first mounting members 231 is plural, and the plurality of first mounting members 231 are distributed along the length direction of the tail side plate 23. The number of second mounting members 201 is also plural, and the plurality of second mounting members 201 are located throughout the lamp structure 200 and correspond to the positions of the plurality of first mounting members 231.

In this way, the mounting fit between the through-lamp structure 200 and the tail side plate 23 is more stable and firm. The first mounting members 231 may be equally spaced along the length direction of the tail side plate 23, so as to ensure uniformity, firmness and reliability of mounting the tail side plate 23 at each position under the condition that the length of the tail side plate 23 is longer. At this time, the plurality of second mounting pieces 201 are also distributed at equal intervals along the length direction penetrating the lamp structure 200.

Referring to fig. 8, in some embodiments, the plurality of first mounting members 231 are stepped in the height direction of the tail side plate 23.

That is, the plurality of first mounting pieces 231 are not positioned on the same horizontal line along the length direction of the tail side plate 23. In this way, the tail side plate 23 can be firmly mounted at different height positions. For example, the plurality of first mounting pieces 231 may be distributed in an arc shape that gradually rises and then gradually falls in the height direction of the tail side plate 23. The area at the left side of the middle position is provided with a plurality of first mounting pieces 231 which are distributed in a step way and gradually rise; the plurality of first mounting members 231 are arranged in a stepped down arrangement in a region to the right of the intermediate position.

Referring to fig. 2, in some embodiments, a pass-through lamp structure 200 includes a pass-through lamp 210 and a pass-through lamp housing 220. The penetrating lamp 210 is disposed on the penetrating lamp housing 220, and the penetrating lamp housing 220 is fixedly connected with the tail side plate 23.

Specifically, the through-lamp housing 220 has an arc-shaped structure, which is adapted to the shape of the tail side plate 23. The penetrating lamp 210 may be disposed at a side of the penetrating lamp housing 220 near the tail side plate 23. The circuit traces running through the lamp 210 may pass through the lamp housing 220 and be housed within the lamp housing 220 for protection. When the penetrating lamp structure 200 is fixedly mounted to the tail base 20, the penetrating lamp structure 200 is fixedly connected to the tail side plate 23 by penetrating the lamp housing 220.

In some embodiments, the through-lamp structure 200 further includes a through-lamp lens 230, the through-lamp lens 230 being disposed on a side of the through-lamp housing 220 opposite the through-lamp 210.

That is, the through-lamp lens 230 is disposed at a side of the through-lamp housing 220 away from the tail side plate 23. Along the direction of the tail side plate 23 to the through-lamp structure 200, the through-lamp housing 220 and the through-lamp lens 230 are sealingly butted to form a complete cavity. The through-lamp lens 230 may have an exit surface upward and downward in the height direction of the vehicle body (i.e., a direction perpendicular to the tail pan 21) and an exit surface rearward in the turbulent flow direction (i.e., a direction in which the air flow passes through the tail structure 100 when the vehicle is traveling normally forward), so that the light emitted through the through-lamp 210 is directed from the tail of the vehicle in all directions.

Referring to fig. 9, in some embodiments, the light emitting direction of the through-lamp 210 is consistent with the length direction of the through-lamp lens 230, and the through-lamp 210 is at least partially located below the height of the through-lamp housing 220.

Since the light emitting direction of the through-lamp 210 is identical to (i.e., parallel or substantially parallel to) the length direction of the through-lamp lens 230, only one through-lamp 210 emitting light sideways is provided at the end of the through-lamp housing 220, and the entire through-lamp lens 230 can be lighted without providing a row of light sources in the length direction of the through-lamp housing 220. In addition, the penetrating lamp 210 is at least partially located below the height of the penetrating lamp housing 220 (including directly below or obliquely below), so that the light emitted by the penetrating lamp 210 can bypass the penetrating lamp housing 220 from the bottom of the penetrating lamp housing 220 to reach the penetrating lamp lens 230 and exit, which is beneficial to reducing light loss.

When the tail structure 100 and the penetrating lamp structure 200 are assembled together, the penetrating lamp 210 may also extend below the tail base 20 to facilitate spatial arrangement of the structure and reduce the width of the tail assembly 300 in the direction of turbulence.

Referring to fig. 3-6, in some embodiments, the tail structure 100 further includes a wind deflector 50. The wind deflector 50 is connected between the tail outer panel 10 and the tail base 20. When the tail outer panel 10 moves relative to the tail base 20, the wind deflector 50 switches between a folded state (the wind deflector 50 has been folded out in fig. 4) and an unfolded state (as shown in fig. 6).

Specifically, the connection of the wind deflector 50 between the tail outer panel 10 and the tail base 20 does not represent that both ends of the wind deflector 50 must be connected to the tail outer panel 10 and the tail base 20, respectively, only that the spatial position of the wind deflector 50 is between the tail outer panel 10 and the tail base 20. For example, one end of the wind deflector 50 is connected to the tail outer panel 10, and the other end of the wind deflector 50 may be connected to the cover 22. When the tail outer panel 10 moves relative to the tail base 20, one end of the wind deflector 50 moves, e.g., lifts or retracts, with the movement of the tail outer panel 10, while the other end of the wind deflector 50 remains at a constant height due to the fixing action of the cover plate 22, so that the distance between the two ends of the wind deflector 50 changes, and the wind deflector 50 can be switched between the folded state and the unfolded state.

According to the embodiment of the application, the wind deflector 50 is arranged between the tail outer plate 10 and the tail base 20, so that the wind deflector 50 can be switched between the folded state and the unfolded state, the air flow between the tail outer plate 10 and the cover plate 22 can be reduced, the air flow is prevented from passing through the opening between the tail outer plate 10 and the cover plate 22, the wind resistance is further reduced, and the folding and storage of the wind deflector 50 are facilitated.

Referring to fig. 10, in some embodiments, the tail outer panel 10 includes an outer panel front end 11 and an outer panel rear end 12 disposed in a spoiler direction. The driving assembly 40 is used for driving the moving assembly 30 to move so as to drive the front end 11 and the rear end 12 of the outer plate to move up and down and/or drive the rear end 12 of the outer plate to move around the front end 11 of the outer plate to turn over. In this way, the movement flexibility of the tail outer plate 10 is higher, the tail outer plate can be adjusted to a proper height and angle, and the wind resistance is better reduced.

Specifically, the turbulent flow direction is the direction in which the airflow passes through the tail structure 100, i.e., the direction from the head to the tail of the automobile, when the automobile is traveling normally forward. When the driving assembly 40 drives the moving assembly 30 to move, driving forces can be respectively applied to the front end 11 and the rear end 12 of the outer panel to control the front and rear ends of the tail outer panel 10 to move in the same or different manners. For example, the outer panel front end 11 is controlled to move upward, the outer panel rear end 12 is controlled to move upward, or the outer panel front end 11 is controlled to move downward, and the outer panel rear end 12 is controlled to move downward, and both the outer panel front end 11 and the outer panel rear end 12 are expressed as lifting motions, the former is the entire rising of the tail outer panel 10, and the latter is the entire falling of the tail outer panel 10.

For example, the outer panel front end 11 is controlled to move upward, the outer panel rear end 12 is controlled to move downward, or the outer panel front end 11 is controlled to move downward, and the outer panel rear end 12 is controlled to move upward, and the outer panel front end 11 and the outer panel rear end 12 are both integrally expressed as a turning motion, the former is turned around the outside on the inside of the tail panel 10, and the latter is turned around the inside on the outside of the tail panel 10.

Referring to fig. 11, in some embodiments, the tail outer panel 10 includes an outer panel center end 13 and an outer panel side end 14 disposed in the vehicle body width direction. Along the direction from the outer panel side end 14 to the outer panel middle end 13, the tail outer panel 10 bulges away from the vehicle body.

That is, the heights of the left and right sides of the tail outer panel 10 are lower than the middle, and the tail outer panel 10 is in a streamline arc shape with a high middle and low sides along the width direction of the vehicle body, so that the lateral resistance in the driving process can be better reduced.

With continued reference to FIG. 11, in some embodiments, the tail outer panel 10 includes an outer panel center end 13 and an outer panel side end 14 disposed in the vehicle body width direction. The tail vane 10 is inclined rearward in the spoiler direction in the direction from the outer vane side end 14 to the outer vane middle end 13.

That is, the tail outer panel 10 has a streamline arc shape with both sides being forward and the middle being rearward in the vehicle width direction, and the longitudinal resistance during running can be reduced better.

Referring to fig. 12 and 13, in some embodiments, when the tail boom outer panel 10 is in the retracted state, the outer panel front end 11 is at a greater elevation than the outer panel rear end 12 (as shown in fig. 12). When the tail outer panel 10 is in the raised state, the height of the outer panel front end 11 is level with the height of the outer panel rear end 12 (as shown in fig. 13).

Thus, when the tail outer plate 10 is in a retracted state, the tail outer plate 10 is high in front and low in back, can be matched with the integral shape of an automobile, and is attractive in appearance. When the tail outer plate 10 is in a lifting state, the front and rear heights of the tail outer plate 10 are consistent, so that the lifting force of the tail of the vehicle can be reduced, and the running wind resistance can be correspondingly reduced.

Referring to fig. 14, in some embodiments, the tail outer panel 10 includes an outer panel 15 and an inner panel 16. The inner layer panel 16 has a rib structure. In this way, the structural strength of the tail outer panel 10 is high.

The inner and outer sides of the tail outer panel 10 are distinguished in the following manner: the side of the tail outer plate 10 close to the tail base 20 is the inner side, and the side of the tail outer plate 10 facing away from or away from the tail base 20 is the outer side. The outer layer 15 is a layer of the tailplane outer plate 10 facing away from or away from the tailplane base 20, and the inner layer 16 is a layer of the tailplane outer plate 10 facing the tailplane base 20. The outer layer 15 and the inner layer 16 may be made of any one or more of aluminum alloy, plastic, carbon fiber, glass fiber reinforced plastic, etc. The outer and inner plates 15, 16 may be fixedly attached together by gluing, screwing, welding, etc. The surface area of the outer layer 15 is larger than that of the inner layer 16 to cover the inner layer 16, thereby protecting the inner layer 16, and the overall appearance of the tail outer panel 10 is also more attractive.

Referring to fig. 6, in some embodiments, the flight base 20 includes a flight base 21, and the drive assembly 40 is disposed on the flight base 21. The driving assembly 40 is used for driving the movement assembly 30 to move so as to drive the tail outer plate 10 to move relative to the tail bottom plate 21.

When the tail structure 100 is mounted on the vehicle body, the tail bottom plate 21 is located in the vehicle body, so that stable mounting of the bottom of the tail structure 100 is facilitated, the tail structure 100 is not easy to shake, and negative lift force generated by air flow on the tail structure 100 is stable. Meanwhile, the driving assembly 40 arranged on the tail bottom plate 21 can be contained in the vehicle body, so that the tail bottom plate 21 and the driving assembly 40 are protected, and the tail bottom plate 21 and the driving assembly 40 cannot occupy the external space of the vehicle body.

In one embodiment, the number of the moving assemblies 30 may be two, and the two moving assemblies 30 are disposed along the width direction of the vehicle body, that is, along the width direction of the tail outer panel 10 and the tail bottom panel 21. At this time, the driving assembly 40 may be disposed at a middle position of the tail base 21 between the two moving assemblies 30. The driving assembly 40 provides driving force simultaneously from two ends of the tail outer plate 10 through the two moving assemblies 30, the driving force is large, and the tail outer plate 10 can move stably, so that the phenomena of side turning and the like are not easy to occur.

With continued reference to fig. 6, in some embodiments, the tail structure 100 further includes a cover 22, the cover 22 being located between the tail outer panel 10 and the tail bottom panel 21. The cover plate 22 is fixedly connected with the tail bottom plate 21; and/or the cover 22 is fixedly coupled to the vehicle body. That is, the cover 22 may be fixedly connected to the tail bottom plate 21; alternatively, the cover 22 is fixedly connected with the vehicle body; alternatively, the cover 22 is fixedly connected to both the tail bottom 21 and the vehicle body. When the tail structure 100 comprises a cover 22, the wind deflector 50 is in particular connected between the tail outer panel 10 and the cover 22.

It should be noted that the cover 22 is located between the tail outer panel 10 and the tail bottom panel 21, and the cover 22 and the tail outer panel 10 may not have a direct connection relationship, and only in a spatial position, the cover 22 is located between the tail outer panel 10 and the tail bottom panel 21. The direction from the top to the bottom of the automobile is the tail outer plate 10, the cover plate 22 and the tail bottom plate 21 in sequence.

The cover 22 remains stationary as the drive assembly 40 drives the movement of the tailplane outer panel 10 relative to the tailplane base 21. The cover 22 may be used to cover or at least partially cover the tailplane 21, the movement assembly 30, the drive assembly 40 within the vehicle body such that the cover 22 may provide protection and aesthetics. The peripheral edge of the cover 22 is tightly coupled to the vehicle body. When the tail outer plate 10 is switched from the lifted state to the retracted state, the tail outer plate 10 is covered on the cover plate 22, the two are integrated, the whole occupied space is small, the car body can not bulge towards the top, and the appearance is attractive.

The wind deflector 50 is located outside the vehicle body, one end of the wind deflector 50 is connected to the tail outer panel 10, and the other end of the wind deflector 50 is connected to the cover 22. One end of the wind deflector 50 moves with the movement of the tail outer panel 10 to be switchable between a folded state and an unfolded state.

In some embodiments, the cover 22 defines a relief 221, and the motion assembly 30 is coupled to the tailplane outer panel 10 via the relief 221.

Specifically, the relief portion 221 may be a relief through hole. When the number of the moving assemblies 30 is two, the number of the avoidance portions 221 is also two, and is located on the cover plate 22 corresponding to the position of the moving assemblies 30. One end of the moving assembly 30 is in driving connection with the driving assembly 40, and the other end of the moving assembly 30 passes through the avoidance portion 221 to be connected with the tail outer panel 10. When the driving assembly 40 drives the moving assembly 30 to move so as to drive the tail outer plate 10, the avoiding portion 221 can avoid the moving assembly 30, so as to provide enough rotation space for the moving assembly 30.

Referring to fig. 6, in some embodiments, the wind deflector 50 is a folded plate and includes a first fold 51 and a second fold 52. The first fold 51 is rotatably connected to the tail outer panel 10 and the second fold 52 is rotatably connected to the cover 22. When the tail outer panel 10 is in the retracted state, the wind deflector 50 is in the folded state; when the tail outer panel 10 is in the raised state, the wind deflector 50 is in the deployed state. The angle between the first folded portion 51 and the second folded portion 52 in the unfolded state is larger than the angle between the first folded portion 51 and the second folded portion 52 in the folded state.

Specifically, the folding direction of the wind deflector 50 is the direction from the tail outer panel 10 to the cover 22. When the wind deflector 50 is in the folded state, the first folded portion 51 overlaps the second folded portion 52, the tail outer panel 10 covers the first folded portion 51, and the second folded portion 52 covers the cover 22. That is, the top-to-bottom tail outer panel 10, the first folded portion 51, the second folded portion 52, and the cover 22 are stacked in this order, so that the space occupation is small and the storage effect is good. When the wind deflector 50 is in the unfolded state, the tail outer panel 10, the first folded portion 51, the second folded portion 52, and the cover 22 are fully unfolded. The angle between the first folded portion 51 and the second folded portion 52 in the unfolded state is larger than the angle between the first folded portion 51 and the second folded portion 52 in the folded state. In one example, the first folded portion 51 and the second folded portion 52 have an acute angle (minimum to 0 degree) in the unfolded state, and the first folded portion 51 and the second folded portion 52 have an obtuse angle (maximum to 180 degrees) in the folded state.

Referring to fig. 15 and 16, in some embodiments, the motion assembly 30 includes a first link 31, a second link 32, a third link 33, and a fourth link 34. The first link 31 is rotatably connected to the second link 32, and the second link 32 is rotatably connected to the third link 33 and the fourth link 34, respectively. The driving assembly 40 is used for driving the first connecting rod 31 to rotate so as to drive the second connecting rod 32 to rotate, and then drive the front end 11 of the outer plate to move through the third connecting rod 33 and/or drive the rear end 12 of the outer plate to move through the fourth connecting rod 34.

When the driving assembly 40 drives the moving assembly 30 to move, the first link 31 is driven to rotate, and the second link 32 is driven to rotate by the rotation of the first link 31. The third connecting rod 33 and the fourth connecting rod 34 are respectively and rotatably connected with the second connecting rod 32 at different positions, so that the second connecting rod 32 can rotate to respectively drive the third connecting rod 33 and the fourth connecting rod 34 to realize different movements. The third connecting rod 33 is connected with the front end 11 of the outer plate (including direct connection or indirect connection), the fourth connecting rod 34 is connected with the rear end 12 of the outer plate (including direct connection or indirect connection), and finally the third connecting rod 33 is driven to drive the front end 11 of the outer plate to move, and the fourth connecting rod 34 is driven to drive the rear end 12 of the outer plate to move, so that the overturning movement or lifting movement of the tail outer plate 10 is realized.

It should be noted that, in addition to the first link 31, the second link 32, the third link 33, and the fourth link 34, the movement assembly 30 may be provided with more links to achieve power transmission, which is not limited herein. The embodiment of the application adopts a small number of connecting rod structures, can realize various movement modes such as turning and/or lifting of the tail outer plate 10, and has a simple and ingenious structure. And the third connecting rod 33 and the fourth connecting rod 34 are both in rotary connection with the second connecting rod 32 to acquire driving force, so that the structure is compact.

Referring to fig. 16, in some embodiments, the first link 31 and the second link 32 are rotatably connected to the first rotating shaft 61, the third link 33 and the second link 32 are rotatably connected to the second rotating shaft 62, and the fourth link 34 and the second link 32 are rotatably connected to the third rotating shaft 63. The connection point of the second rotation shaft 62 and the second link 32 is located between the connection point of the first rotation shaft 61 and the second link 32 and the connection point of the third rotation shaft 63 and the second link 32.

That is, the first link 31, the third link 33, and the fourth link 34 are all rotatably connected to the second link 32, and the corresponding connection points are sequentially arranged on the second link 32. Thus, when the driving assembly 40 drives the first link 31 to rotate, the second rotating shaft 62 corresponding to the connecting point located in the middle further corresponds to the third link 33, which can provide a relatively small driving force for the front end 11 of the outer plate, and the third rotating shaft 63 corresponding to the connecting point located at the edge further corresponds to the fourth link 34, which can provide a relatively large driving force for the rear end 12 of the outer plate, so that when the tail outer plate 10 performs a turning motion, the rear end 12 of the outer plate turns around the front end 11 of the outer plate, and better airflow guiding is achieved after the motion is completed.

Further, in the foregoing embodiment, when the tail outer panel 10 is in the retracted state, the outer panel front end 11 is at a greater height than the outer panel rear end 12. And when the tail outer panel 10 is in a raised state, the height of the outer panel front end 11 is equal to the height of the outer panel rear end 12. That is, the amplitude of the motion of the outer panel rear end 12 needs to be larger than that of the outer panel front end 11. Therefore, the driving force of the outer panel rear end 12 is greater than that of the outer panel front end 11, and can be well adapted to the required movement amplitude, so that the tail panel 10 moves to an optimum aerodynamic performance state.

Referring to fig. 16, in some embodiments, the movement assembly 30 further includes a screw 35, and the driving assembly 40 drives the first link 31 to rotate through the screw 35. In this case, the driving assembly 40 may be a motor.

When the number of the moving assemblies 30 is two, the first connecting rod 31, the second connecting rod 32, the third connecting rod 33 and the fourth connecting rod 34 are symmetrically arranged on two sides of the tail bottom plate 21, and two ends of the screw rod 35 respectively drive the first connecting rods 31 on two sides.

In certain embodiments, the tail structure 100 further comprises a floor connection assembly 70. The floor connection assembly 70 includes a first connection member 71. One end of the first connecting member 71 is sleeved on the screw rod 35, and the other end of the first connecting member 71 is rotatably connected to the fourth rotating shaft 64 with the first connecting rod 31.

Specifically, when the driving assembly 40 drives the screw rod 35 to move, one end of the first connecting member 71 is fixed relative to the screw rod 35, i.e. does not rotate relative to the screw rod 35, the other end of the first connecting member 71 drives one end of the first connecting rod 31 to rotate, and then drives the second connecting rod 32 to rotate through the other end of the first connecting rod 31, so as to drive the front end 11 of the outer plate to move through the third connecting rod 33, and drive the rear end 12 of the outer plate to move through the fourth connecting rod 34. The first link 71 is provided to facilitate the transmission of power from the screw 35 to the first link 31.

In certain embodiments, the floor attachment assembly 70 further includes a second attachment member 72 and an attachment base 74. The second connector 72 is fixedly connected to the connection base 74. One end of the second connecting piece 72 is sleeved on the screw rod 35, and the other end of the second connecting piece 72 and the second connecting rod 32 are rotatably connected to the fifth rotating shaft 65. The connection point of the fifth rotation shaft 65 and the second link 32 is located at a side of the connection point of the first rotation shaft 61 and the second link 32, which is away from the connection point of the third rotation shaft 63 and the second link 32.

Specifically, the connection base 74 may be fixedly mounted on the tail bottom plate 21, for example, by screws. When the driving assembly 40 drives the screw rod 35 to move, the second connecting piece 72 is fixedly connected with the connecting base 74, so that the second connecting piece 72 cannot move, and the connecting point of the fifth rotating shaft 65 and the second connecting rod 32 can limit the end part of the second connecting rod 32, so that the second connecting rod 32 moves around the end part from the other end during movement, and further drives the third connecting rod 33 and the fourth connecting rod 34 at the other end to move.

In addition, the second connecting piece 72 can be located between the driving assembly 40 and the first connecting piece 71, and the second connecting piece 72 and the first connecting rod 31 are rotationally connected with the second connecting rod 32 by the opposite side of the second connecting rod 32, so that the avoidance of the movement space is realized, and the overall structure is compact.

Referring to fig. 17, in some embodiments, a connection section formed by a connection point of the fifth rotating shaft 65 and the second connecting rod 32 and a connection point of the first rotating shaft 61 and the second connecting rod 32 are not on the same straight line with a connection section formed by a connection point of the second rotating shaft 62 and the second connecting rod 32 and a connection point of the third rotating shaft 63 and the second connecting rod 32.

Specifically, the connection section formed by the connection point of the fifth rotating shaft 65 and the second connecting rod 32 and the connection point of the first rotating shaft 61 and the second connecting rod 32 is a straight line section, the connection section formed by the connection point of the second rotating shaft 62 and the second connecting rod 32 and the connection point of the third rotating shaft 63 and the second connecting rod 32 is also a straight line section, and the connection point of the first rotating shaft 61 and the second connecting rod 32 and the connection point of the second rotating shaft 62 and the second connecting rod 32 are arc sections so as to realize turning of driving directions and positions and provide driving forces with proper directions and magnitudes for the front end 11 and the rear end 12 of the outer plate respectively.

Referring to fig. 16, in some embodiments, the tail structure 100 further includes an outer panel connection assembly 80. The outer panel connector includes a first connection portion 81 and a second connection portion 82 extending from the first connection portion 81. The first connection portion 81 is for fixedly connecting with the tail outer panel 10, and the second connection portion 82 is for rotatably connecting with the third link 33 and the fourth link 34. In embodiments of the present application, the provision of the outer panel connection assembly 80 may facilitate the physical connection and force transfer between the motion assembly 30 and the tail outer panel 10.

Specifically, the second connection portion 82 and the first connection portion 81 form an included angle therebetween, for example, the two are disposed vertically. In one example, the first connection portion 81 is disposed in parallel with the tail outer panel 10, and the second connection portion 82 is disposed in the vertical direction to transmit the link driving force in the vertical direction to the horizontally disposed tail outer panel 10.

Further, the third link 33 and the fourth link 34 may be rotatably connected to the second connecting portion 82 by opposite sides of the second connecting portion 82, so that the rotation of the third link 33 and the fourth link 34 may avoid each other, and are not easy to affect each other. At this time, the length of the second rotating shaft 62 may be different from the length of the third rotating shaft 63. For example, the length of the second rotating shaft 62 is longer than the length of the third rotating shaft 63 (as shown in fig. 19), so as to realize that the third link 33 and the fourth link 34 are rotatably connected with the second connecting portion 82 by opposite sides of the second connecting portion 82.

Referring to fig. 13 and 16, in some embodiments, the second connection 82 includes a front end connection region 821 corresponding to the outer panel front end 11 and a rear end connection region 822 corresponding to the outer panel rear end 12. The third link 33 is rotatably connected to the sixth rotating shaft 66 with the front end connecting area 821, and the fourth link 34 is rotatably connected to the seventh rotating shaft 67 with the rear end connecting area 822.

In this way, the driving force can be transmitted to the front end 11 of the outer plate through the front end connecting area 821, the driving force can be transmitted to the rear end 12 of the outer plate through the rear end connecting area 822, the driving positions can be mutually avoided, and the structural design is reasonable.

Referring to fig. 16, in some embodiments, the tail structure 100 further includes a floor connection assembly 70. The floor connection assembly 70 further includes a third connection member 73 and a connection base 74. One end of the third connecting member 73 is rotatably connected to the eighth rotating shaft 68 with the connecting base 74, and the other end of the third connecting member 73 is rotatably connected to the ninth rotating shaft 69 with the third connecting rod 33. The connection point of the ninth rotation shaft 69 and the third link 33 is located at a side of the connection point of the second rotation shaft 62 and the third link 33, which is away from the connection point of the sixth rotation shaft 66 and the third link 33.

Specifically, the connection base 74 may be fixedly mounted on the tail bottom plate 21, for example, by screws. When the driving assembly 40 drives the moving assembly 30 to move, specifically drives the third link 33 to rotate, since one end of the third connecting member 73 is rotationally connected with the connecting base 74, the third connecting member 73 rotates around the eighth rotating shaft 68, and thus, both the connection portion of the third link 33 and the third connecting member 73 and the connection portion of the second link 32 rotate, specifically, the third link 33 drives the outer panel front end 11 to turn inwards through the sixth rotating shaft 66.

Further, referring to fig. 18, the included angle between the connection section formed by the connection point of the ninth rotating shaft 69 and the third connecting rod 33 and the connection point of the second rotating shaft 62 and the third connecting rod 33 and the connection section formed by the connection point of the sixth rotating shaft 66 and the third connecting rod 33 are obtuse angles. Thus, when the third link 33 is driven to rotate, the connection point between the ninth rotating shaft 69 and the third link 33 and the connection point between the second rotating shaft 62 and the third link 33 are all in the condition of rotation lifting, so that the connection point between the sixth rotating shaft 66 and the third link 33 can be rotated and lowered, and the front end 11 of the outer plate is driven to turn inwards.

Referring to fig. 19, in some embodiments, the third link 33 and the fourth link 34 are rotatably coupled to the second link 32 by the same side of the second link 32. The length of the second rotation shaft 62 between the second link 32 and the third link 33 is longer than the length of the third rotation shaft 63 between the second link 32 and the fourth link 34. In this way, the rotation of the third connecting rod 33 and the fourth connecting rod 34 can avoid each other, the mutual influence is not easy, and the structural design is compact.

Referring to fig. 6 and 16, in some embodiments, the tail structure 100 further includes a displacement adjustment assembly 90. The first connection portion 81 is connected to the tail outer panel 10 through the displacement adjustment assembly 90. The displacement adjustment assembly 90 is capable of adjusting the position of the tail outer panel 10 relative to the first connection 81 in a direction parallel to the plane in which the first connection 81 lies and/or perpendicular to the first connection 81.

Specifically, the displacement adjustment assembly 90 is, for example, a tolerance adjuster. The displacement adjustment assembly 90 is provided to adjust the position of the tail outer panel 10 in three dimensions, including, for example, the X-direction and the Y-direction in a plane parallel to the first connection portion 81, and including, for example, the Z-direction in a direction perpendicular to the first connection portion 81. After the movement assembly 30 drives the tail outer plate 10 to turn over and/or lift, if the required height position and the required turning angle cannot be accurately achieved, fine adjustment can be performed through the displacement adjustment assembly 90, so that the position parameters of the tail outer plate 10 are more accurate. The adjustment of the position of the displacement adjustment assembly 90 with respect to the tail outer panel 10 can be performed in real time during operation or can be tested and adjusted before the tail structure 100 leaves the factory.

Referring to fig. 4 and 6, in some embodiments, the tail structure 100 further includes a controller 110 electrically connected to the drive assembly 40. The controller 110 is used for controlling the driving assembly 40 to drive the movement assembly 30 to move so as to drive the tail outer panel 10 to move relative to the tail base 20.

Specifically, the controller 110 may be located within the vehicle body and electrically connected to the drive assembly 40 via wiring on the tailplane floor 21 to provide control signals to the drive assembly 40 to drive the tailplane outer panel 10 into movement, such as a roll-over movement and/or a lift movement, to achieve a raised or retracted state, or other more states, of the tailplane outer panel 10.

In summary, in the tail assembly 300 and the automobile according to the embodiments of the present application, the driving assembly 40 is configured to drive the movement assembly 30 to move, so as to drive the tail outer panel 10 to move relative to the tail base 20, so as to reduce lift force of the automobile, improve stability of the automobile during high-speed driving, and reduce wind resistance of the automobile during high-speed driving. In addition, the penetrating lamp structure 200 is fixedly mounted on the tail base 20, so that the tail structure 100 and the penetrating lamp structure 200 are integrated integrally, the mounting process can be simplified, and the two are matched with each other more robustly.
