For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0046] It should be noted that the front (or forward) and rear (or rearward) mentioned in this article are with reference to the vehicle, that is, the direction pointed by the front of the vehicle is the front, and the direction pointed by the rear of the vehicle is the rear.

[0047] The back door is also called the tailgate, and is widely used in vehicles such as hatchback sedans and SUVs (Sport Utility Vehicles). By opening the back door, luggage and other items in the trunk can be easily taken out.

[0048] In the related art, the back door is movably connected to the vehicle body through a hinge. Generally speaking, when the back door is closed, the smaller the gap between the back door and the vehicle body ceiling, the better the appearance of the vehicle. However, when the gap is small, the back door is prone to interfere with the vehicle body ceiling when in motion. Therefore, it is necessary to consider how to reduce the risk of interference between the back door and the vehicle body ceiling when in motion.

[0049] In order to solve the above technical problems, the embodiment of the present application provides a vehicle, which includes a vehicle body and a rear door. Figure 1 and Figure 2 A vehicle provided in an embodiment of the present application is introduced in detail.

[0050] Figure 1 A partial cross-sectional structural schematic diagram of a vehicle provided in an embodiment of the present application is shown, in which the right side of the figure is a partial body of the vehicle, and the left side is a partial structure of a rear door 20 . Figure 1 The back door 20 at the rear of the vehicle is in a closed state.

[0051] refer to Figure 1 The vehicle body includes a roof 10, a back door 20 is movably connected to the vehicle body, and the back door 20 can move relative to the roof 10 between an open position and a closed position; the back door 20 includes a back door outer panel 21 and a back door inner panel 22, the top surface of the back door outer panel 21 is flush with the top surface of the roof 10, the back door inner panel 22 includes a back door inner panel body 221, a first bending portion 222 and a second bending portion 223, the first bending portion 222 connects the back door inner panel body 221 and the second bending portion 223, and the second bending portion 223 is connected to the back door outer panel 21. The back door inner panel body 221 has a bottom surface 2211, the first bending portion 222 has an inclined surface 2221, and the angle between the inclined surface 2221 and the bottom surface 2211 is an obtuse angle.

[0052] In the solution provided by the embodiment of the present application, the back door inner panel body 221 is connected to the second bent portion 223 through the first bent portion 222, and the second bent portion 223 is connected to the back door outer panel 21. The angle between the inclined surface 2221 of the first bent portion 222 and the bottom surface 2211 of the back door inner panel body 221 is an obtuse angle. In this way, the first bent portion 222 constitutes an avoidance structure on the back door inner panel 22, so that a missing angle is formed in the front lower part of the back door inner panel 22. Therefore, during the opening and closing process of the back door 20, the missing angle can form an avoidance with the ceiling 10, thereby reducing the risk of interference between the back door 20 and the vehicle body ceiling 10 when the back door 20 moves.

[0053] The tailgate 20 is rotatably connected to the vehicle body, and the specific connection position may be the roof 10 or the side of the vehicle body. Undoubtedly, the tailgate 20 and the vehicle body can be rotated and supported by a hinge and a strut in the prior art, or by a four-link hinge in combination with a strut in the prior art. The strut in the prior art is a rod-shaped driving device that can be extended and shortened. Specifically, one end of the strut is rotatably connected to the vehicle body, and the other end is rotatably connected to the tailgate 20. When the length of the strut changes, it can drive the tailgate 20 to move.

[0054] The following is in conjunction with the instruction manual Figure 1 and 2 The specific structure of the vehicle of the present application is introduced in detail.

[0055] The roof 10 is located on the top of the vehicle and is used to isolate the interior space of the vehicle from the outside world. It can not only provide shelter from wind and rain, but also provide heat insulation and sound insulation. The roof 10 may include a roof outer panel 11 and a roof inner panel 12, and the roof inner panel 12 is connected to the roof outer panel 11. The roof outer panel 11 may include a roof outer panel body 111 disposed on the outermost side of the vehicle body. The roof outer panel body 111 is usually made of sheet metal and has the advantages of high strength, light weight, easy processing, corrosion resistance, and beautiful appearance. In addition, the ceiling outer panel 11 can also include a ceiling reinforcement plate 112. The edge of the ceiling reinforcement plate 112 is fixedly connected to the ceiling outer panel body 111 by welding, riveting, etc., and the middle part of the ceiling reinforcement plate 112 is separated from the ceiling outer panel body 111, so that the cross-section of the ceiling outer panel 11 forms a U-shape, that is, a space with a U-shape cross-section is reserved between the ceiling reinforcement plate 112 and the ceiling outer panel body 111. This space causes the ceiling reinforcement plate 112 and the ceiling outer panel body 111 to bend, thereby improving the overall structural strength of the ceiling outer panel 11.

[0056] The back door 20 is movably connected to the vehicle body through a movable hinge, and can move relative to the ceiling 10 between an open position and a closed position under the action of a driving member (not shown in the figure). The movable hinge can at least realize the movement of the back door 20 between the open position and the closed position relative to the ceiling 10. Although not shown in the figure, it is easy to think that in one possible implementation, the movable hinge can adopt a pivot, and the back door 20 can be rotated from the closed position to the open position. In addition, in another possible implementation, the movable hinge can also adopt a multi-link mechanism, such as a four-link mechanism. In this case, during the process of opening the back door 20, the movement trajectory of the back door 20 is not an arc, thereby realizing a diversified movement trajectory design. The driving member is installed on the vehicle body and connected to the back door 20, and can drive the back door 20 to move relative to the ceiling 10 between the open position and the closed position. The driving member is a telescopic member, one end of which is rotatably connected to the vehicle body, and the other end is rotatably connected to the back door 20. For example, the driving member can be a telescopic cylinder, a telescopic hydraulic cylinder or an electric cylinder (also called a strut). For the specific driving components used, technicians in this field can adapt the corresponding air source, hydraulic station, distribution lines, etc. The details of setting the driving components are relatively simple for technicians in this field, so for the sake of brevity, they will not be repeated here.

[0057] In order to show the back door 20 more clearly, Figure 2 Omitted Figure 1 The back door outer panel 21 includes a back door outer panel body 211. The back door outer panel body 211 is usually made of sheet metal, so it has the advantages of high strength, light weight, easy processing, corrosion resistance and beautiful appearance. In addition, the back door outer panel 21 may also include a back door reinforcement plate 212, the first end of the back door reinforcement plate 212 is connected to the edge of the back door outer panel body 211, and the second end of the back door reinforcement plate 212 is a cantilever end 2121, wherein the second bending portion 223 is connected to the back door reinforcement plate 212. Since the second end of the back door reinforcement plate 212 is a cantilever end 2121, that is, it is cantilevered, it can achieve a certain degree of free swing when subjected to external force, so the back door reinforcement plate 212 can further play a role in buffering and absorbing vibration on the basis of enhancing the strength of the back door outer panel 21. Exemplarily, the back door reinforcement plate 212 can be connected to the back door outer panel 21 by welding, riveting or screw connection.

[0058] The portion of the back door reinforcement plate 212 between the first end and the second end is formed with a curved portion 2122, and the curved portion 2122 protrudes outwardly away from the back door outer plate body 211. The vehicle also includes a seal 13, and the seal 13 is installed at the rear end of the roof 10. When the back door 20 is in a closed position, the curved portion 2122 presses the seal 13 to seal the roof 10 and the back door 20, thereby preventing external dust and moisture from entering the interior of the vehicle body. Among them, the seal 13 can be a sealing strip. The sealing strip is an elastic band or rod-shaped structure, and can be made of EPDM, polyvinyl chloride, plasticized polyvinyl chloride, chloroprene rubber, etc. Among them, EPDM has outstanding ozone resistance, excellent weather resistance, good high temperature and low temperature resistance, and outstanding chemical resistance, so it has been widely used as a material for sealing strips.

[0059] The third end and the fourth end of the back door reinforcement plate 212 are connected to the back door outer panel body 211. It can be understood that the first end and the second end of the back door reinforcement plate 212 are the two ends of the back door reinforcement plate 212 along the front-to-back direction of the vehicle, wherein the first end is the front end and the second end is the rear end; the third end and the fourth end are the two ends of the back door reinforcement plate 212 along the left-right direction of the vehicle. This arrangement allows the back door reinforcement plate 212 to have multiple connection points with the back door outer panel body 211, thereby improving the connection stability between the back door reinforcement plate 212 and the back door outer panel body 211. Exemplarily, the third end and the fourth end can be connected to the back door outer panel body 211 by welding, riveting, hook and loop.

[0060] In one embodiment, a groove portion 115 is formed at the rear end of the roof outer panel 11, and the seal 13 is fixed to the rear end of the groove portion 115. The groove portion 115 can serve as a water flow channel structure at the rear end of the roof 10, and the cooperation between the water flow channel structure and the seal 13 can better prevent external water from entering the vehicle compartment.

[0061] Furthermore, a protrusion 201 extending forward may be formed at the front end of the back door 20. When the back door 20 is in a closed state, the protrusion 201 is located above the recessed portion 115. The provision of the protrusion 201 is conducive to reducing the gap between the top surface of the back door 20 and the top surface of the ceiling 10, thereby improving the external aesthetics of the vehicle. It is understandable that when the back door 20 is connected to the vehicle body through a single-axis hinge structure, the recessed portion 115 also has the function of avoiding the protrusion 201. That is, when the back door 20 is opened in a rotating manner, the protrusion 201 can enter the avoidance space defined by the recessed portion 115 to ensure that the back door 20 can be opened smoothly.

[0062] The seal 13 may include a mounting base 131 and a lip 132, wherein the mounting base 131 is fixed to the rear end of the groove portion 115, the lip 132 is connected to the mounting base 131, and the lip 132 abuts against the ceiling inner plate 12. The lip 132 may be integrally injection molded with the mounting base 131. In this way, the seal 13 may play a role in sealing and protecting the joint between the ceiling outer plate 11 and the ceiling inner plate 12, thereby preventing dust from entering the joint.

[0063] In some embodiments, the second bent portion 223 is connected to the back door reinforcement plate 212 by overlapping. The overlapping length of the second bent portion 223 and the back door reinforcement plate 212 can be greater than or equal to 1 mm, for example, 1 mm, 1.2 mm, 1.5 mm, etc. In this way, the connection strength between the second bent portion 223 and the back door reinforcement plate 212 can be improved.

[0064] In one embodiment, the back door inner panel 22 may include a back door substrate layer 224 and a back door covering layer 225, one end of the back door substrate layer 224 is connected to the back door outer panel 21, the back door covering layer 225 covers the surface of the back door substrate layer 224 and one end is connected to the back door outer panel 21, and the bottom surface 2211 and the inclined surface 2221 are both located in the back door covering layer 225. The back door substrate layer 224 may be made of PU foam sheet, PP foam sheet, corrugated paper, resin-impregnated recycled cotton or glass fiber, etc., and the back door covering layer 225 may be made of fabric material, genuine leather material and artificial leather material. Fabric material has good durability, strong air permeability, and good surface anti-slip effect; genuine leather material has a high-end look and feel, high comfort, and the surface leather is not easy to penetrate water and is easy to clean and maintain. Artificial leather material is generally made of woven fabric bonded with polyvinyl chloride or polyurethane, with a surface similar to genuine leather and a variety of colors, easy to clean and maintain, and affordable. The back door covering layer 225 made of different materials can achieve corresponding effects. Those skilled in the art can flexibly select appropriate materials as the back door covering layer 225 according to actual needs. It can be understood that the bottom surface 2211 and the inclined surface 2221 are both located on the back door covering layer 225, which means that the bottom surface 2211 and the inclined surface 2221 are both formed on the back door covering layer 225. In other words, the bottom surface 2211 and the inclined surface 2221 are both part of the outer surface of the back door covering layer 225. In some embodiments, the angle between the inclined surface 2221 of the first bending portion 222 and the bottom surface 2211 of the back door inner plate body 221 is greater than or equal to 120° and less than or equal to 150°. If the angle between the inclined surface 2221 and the bottom surface 2211 is too large or too small, the missing corner of the front lower part of the back door inner plate 22 will become less obvious, thereby affecting the avoidance effect of the missing corner. Therefore, in this embodiment, the angle between the inclined surface 2221 and the bottom surface 2211 is limited to 120° to 150°. In this case, the missing angle is obvious and the avoidance effect is better.

[0065] Although not shown in the figure, it is understandable that many variations are possible without departing from the technical concept of the present application. For example, the tailgate 20 can be an integral fastback tailgate or an integral hatchback tailgate. In addition, the tailgate 20 in the embodiment of the present application can also be an upper tailgate in a split tailgate. The split tailgate includes an upper back and a lower back, and the upper back and the lower back can be opened and closed independently. The split tailgate can refine the use space of the trunk and can place items more conveniently.
