[0040] Therefore, by forming the spoiler portion 11 on the back door outer panel 10 and forming the outer side surface of the spoiler portion 11 as a spoiler surface, the spoiler plate structure does not need to be separately provided, compared to the structure in the prior art in which the spoiler plate assembly is bolted to the back door assembly 100, the assembly process of the back door outer panel 10 in the present application is simple, the number of parts is small, and the weight of the formed back door outer panel 10 is small, which is beneficial to lightweight design, at the same time, the support structure is located in the installation space 30 between the back door outer panel 10 and the back door inner panel 20, and the support structure is supported between the spoiler portion 11 and the back door inner panel 20, so as to play a supporting role on the spoiler portion 11 through the support structure, so as to enhance the structural strength of the spoiler portion 11 and avoid deformation, which is beneficial to reduce production cost.

[0041] For example, as shown in Figure 1 , the back door assembly 100 is installed on the vehicle body, and as shown in Figure 3 , the spoiler portion 11 is integrated on the back door outer panel 10, and the outer side surface of the spoiler portion 11 (the side surface of the spoiler portion 11 away from the back door inner panel 20) is formed as a spoiler surface, i.e. the spoiler portion 11 is integrally formed with the back door outer panel 10, so that the spoiler plate structure does not need to be separately provided, and the spoiler surface can play a spoiler role, which is beneficial to simplify the assembly process.

[0042] In this embodiment, the back door outer panel 10 is formed by injection molding, and in actual installation, as shown in Figure 2 , Figure 6 and Figure 7As shown, the support structure is first installed on the back door inner plate 20, then the back door inner plate 20 is installed on the vehicle body 200, and then the back door outer plate 10 is bonded to the back door inner plate 20 using glue to form a waterproof closed space structure. Optionally, the material of the back door outer plate 10 uses PC (polycarbonate) + ABS (polycarbonate, acrylonitrile-butadiene-styrene copolymer) material, which facilitates to enhance the rigidity of the back door outer plate 10 and is beneficial to reduce the weight thereof.

[0043] Further, as shown in Figure 4 and Figure 5 , the support structure is supported between the spoiler portion 11 and the back door inner plate 20, so that the support structure plays a supporting role on the spoiler portion 11. The support structure can be configured as a support frame, or a reinforcing rib, or a support plate 40, or a filling material, etc., so as to be able to play a supporting role on the spoiler portion 11 to enhance the rigidity of the spoiler portion 11 and avoid deformation thereof.

[0044] According to the back door assembly 100 of the embodiment of the present application, the spoiler portion 11 is formed on the back door outer plate 10, and the outer side surface of the spoiler portion 11 is formed as a spoiler surface, so that a spoiler plate structure does not need to be separately provided, which facilitates to realize lightweight design of the back door assembly 100. The support structure is located in the installation space 30 and supported between the spoiler portion 11 and the back door inner plate 20, which is further beneficial to enhance the structural strength of the spoiler portion 11, avoid deformation thereof, and reduce production cost.

[0045] In some embodiments, as shown in Figure 4 and Figure 5 , the support structure includes a support plate 40, the upper end of the support plate 40 is supported on the lower side of the spoiler portion 11, and the lower end of the support plate 40 is connected to the back door inner plate 20.

[0046] Thus, the support plate 40 is supported between the spoiler portion 11 and the back door inner plate 20 to play a supporting role on the spoiler portion 11, so as to avoid the problem of collapse of the spoiler portion 11, enhance the structural strength of the spoiler portion 11, and the structure of the support plate 40 is simpler, easy to assemble and beneficial to reduce production cost.

[0047] In some embodiments, the support plate 40 has a "Z" shape in cross section. In other words, the support plate 40 is composed of a frame injection molded piece with a "Z" shape in cross section. On the one hand, this can ensure that the support plate 40 has sufficient structural strength, and on the other hand, it is beneficial to reduce the weight of the support plate 40 to realize lightweight design of the support plate 40.

[0048] In some embodiments, a high brake light is installed at the rear end of the back door assembly 100, as shown in Figure 4 and Figure 5As shown, the support plate 40 is arranged to be inclined towards the front side in the front-rear direction so as to avoid the high brake lamp.

[0049] In some embodiments, as shown in Figure 4 , Figure 5 the support plate 40 comprises a main body portion 41 and an inclined portion 42.

[0050] The main body portion 41 is connected with the rear door inner panel 20, and the inclined portion 42 is connected with the spoiler portion 11.

[0051] Thus, the main body portion 41 can ensure sufficient structural strength for the support plate 40, and the inclined portion 42 is arranged so that the upper surface of the inclined portion 42 forms a support surface connected with the spoiler portion 11, so as to increase the support area of the support plate 40 on the spoiler portion 11, thereby enhancing the structural strength of the spoiler portion 11.

[0052] Optionally, the support plate 40 and the rear door inner panel 20 are integrally injection molded.

[0053] Thus, the support plate 40 and the rear door inner panel 20 can be integrally formed, which can enhance the connection stability of the support plate 40 and the rear door inner panel 20, and does not need to be fixed separately, which is beneficial to simplify the installation structure and reduce the production cost.

[0054] At the same time, the overall weight of the support plate 40 and the rear door inner panel 20 is small, the strength is high, and the safety performance is better, which is beneficial to the lightweight of the electric vehicle and can effectively prolong the cruising range of the electric vehicle.

[0055] In some embodiments, as shown in Figure 2 , Figure 6 and Figure 7 the rear door inner panel 20 is provided with a first support beam 51, and the first support beam 51 is supported between the rear end of the rear door inner panel 20 and the support plate 40.

[0056] Thus, by arranging the first support beam 51, the support plate 40 is supported on the rear side of the support plate 40, so as to enhance the structural stability of the support plate 40, thereby enhancing the support effect of the support plate 40 on the spoiler portion 11, i.e. indirectly enhancing the structural strength of the spoiler portion 11.

[0057] Further, as shown in Figure 2 the first support beam 51 is provided in plurality, and the plurality of first support beams 51 are distributed in the transverse direction of the rear door inner panel 20.

[0058] Therefore, by arranging the plurality of first support beams 51 to be distributed in the lateral direction, the plurality of first support beams 51 can support the support plate 40 at different positions in the lateral direction of the support plate 40, so as to enhance the structural stability of the support plate 40, and further enhance the support effect of the support plate 40 on the spoiler 11, i.e. indirectly enhance the structural strength of the spoiler 11.

[0059] Preferably, the first support beam 51 is connected to the connection between the support plate 40 and the back door inner panel 20, so as to enhance the local rigidity of the connection between the support plate 40 and the back door inner panel 20.

[0060] Optionally, as shown in Figure 2 , a reinforcing plate 53 is connected between two adjacent first support beams 51.

[0061] Therefore, the plurality of first support beams 51 can be sequentially connected by the reinforcing plate 53, so as to enhance the structural stability of the plurality of first support beams 51, and further enhance the support effect of the first support beam 51 on the support plate 40.

[0062] In some embodiments, as shown in Figure 2 , Figure 6 and Figure 7 , the back door inner panel 20 is provided with a second support beam 52, and the second support beam 52 is connected between the front end of the back door inner panel 20 and the support plate 40.

[0063] Therefore, by arranging the second support beam 52, the support plate 40 can be supported on the front side, so as to enhance the structural stability of the support plate 40, and further enhance the support effect of the support plate 40 on the spoiler 11, i.e. indirectly enhance the structural strength of the spoiler 11.

[0064] Preferably, the second support beam 52 is connected to the connection between the support plate 40 and the back door inner panel 20, so as to enhance the local rigidity of the connection between the support plate 40 and the back door inner panel 20.

[0065] In some embodiments, a buffer 50 is arranged between the upper end of the support plate 40 and the lower side of the spoiler 11.

[0066] Therefore, the support plate 40 and the spoiler 11 are in soft contact, on the one hand, the buffer 50 can reduce the vibration transmission between the support plate 40 and the spoiler 11, on the other hand, the buffer 50 can separate the support plate 40 and the spoiler 11, since the structural strength of the support plate 40 and the spoiler 11 is high, the buffer 50 can avoid rigid collision between the two, so as to protect the spoiler 11 and the support plate 40.

[0067] For example, the buffer 50 can be configured as a sponge strip, or the buffer 50 can be configured as other buffer structures, which are not limited herein.

[0068] In some embodiments, as shown in Figure 3 The rear door outer plate 10 further comprises a mounting portion 12, the spoiler portion 11 is connected with the mounting portion 12, and the mounting portion 12 is used to be connected with the rear door inner plate 20. The spoiler portion 11 is connected with the mounting portion 12 by bending, and the connection position extends outwardly and rearwardly. In other words, the connection position extends towards the direction of the tail of the vehicle.

[0069] Therefore, by arranging the mounting portion 12, the rear door outer plate 10 is connected with the rear door inner plate 20, and the spoiler portion 11 and the mounting portion 12 are connected by bending so as to form the spoiler surface on the outer side of the spoiler portion 11.
