[0002] Existing vehicle taillights are generally installed on the rear side of the side panel of the vehicle. Due to the processing restrictions of the sheet metal structure of the side panel, it is difficult to balance the reliability of the vehicle body structure and the luminous area of ​​the taillights. Utility Model Content

[0003] The present application provides a taillight mounting structure, a rear vehicle body assembly and a vehicle to solve the technical problem that the existing taillight mounting structure cannot take into account both structural reliability and guarantee of the taillight luminous area.

[0004] In a first aspect, the present application provides a taillight mounting structure, which is used to mount a first taillight of a vehicle, and the taillight mounting structure includes a first mounting member and a second mounting member. The first mounting member includes a first bottom plate and a first side plate, and the first side plate is bent and connected to one side of the first bottom plate along the Z direction of the vehicle. The second mounting member includes a second side plate, and the second side plate is connected to the other side of the first bottom plate along the Z direction, and the second mounting member and the first mounting member form a receiving groove, and the receiving groove is used to receive the first taillight, and the receiving groove extends from the front of the vehicle in the X direction to the rear of the vehicle in the X direction. Wherein, the second side plate is inclined relative to the first side plate, and the inclination direction is that the end of the second side plate away from the first bottom plate is inclined toward the direction away from the first side plate, and the angle between the second side plate and the first plane perpendicular to the Z direction is α, and α≤10°.

[0040] DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0042] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be a centered element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may also be a centered element. When an element is considered to be "set on" another element, it may be directly set on the other element or there may also be a centered element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

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

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

[0045] In the present application, refer to Figure 1 and Figure 2 , this embodiment provides a vehicle 300, which may be a fuel vehicle, an electric vehicle, a hybrid vehicle, or other types of vehicles.

[0046] For the convenience of description, in this embodiment, the X direction of the vehicle 300 is defined as the front-to-back direction (i.e., the length direction) of the vehicle 300, and the Y direction of the vehicle 300 is defined as the left-to-right direction (i.e., the width direction) of the vehicle 300. The Z direction is the up-down direction (i.e., the height direction) of the vehicle 300. In general, the X direction, the Y direction, and the Z direction are three directions that are perpendicular to each other in the vehicle rectangular coordinate system.

[0047] See also Figure 2 In this embodiment, the vehicle 300 includes a body 303, a side panel structure 202, and a taillight. The taillight is arranged at the rear of the body 303 (i.e., the rear of the vehicle 300 along the X direction), and the taillight is used to achieve brake warning, turn prompt, outline indication and other effects through light. In a general vehicle, the taillights can be arranged on both sides of the rear of the vehicle 300 in the Y direction (width direction). The rear of the body 303 is also provided with a rear door 301.

[0048] The taillights on each side of the vehicle 300 may be configured to include a first taillight 201 and a second taillight 302, wherein the first taillight 201 is connected to the side panel structure 202 at the rear of the vehicle body 303, and the second taillight 302 is connected to the rear door 301 of the vehicle 300. When the rear door 301 is closed, the second taillight 302 and the first taillight 201 are combined to form a taillight with a larger light-emitting area.

[0049] See also Figures 3 to 5 The vehicle 300 of this embodiment further includes a taillight mounting structure 100 , and the taillight mounting structure 100 is used to mount the first taillight 201 of the vehicle 300 .

[0050] The taillight mounting structure 100 includes a first mounting member 10 and a second mounting member 20. The first mounting member 10 includes a first bottom plate 11 and a first side plate 12. The first side plate 12 is bent and connected to one side of the first bottom plate 11 along the Z direction of the vehicle 300 (eg Figure 3 The first mounting member 10 can be formed by stamping and bending a plate, with one side of the bending serving as the first bottom plate 11 and the other side serving as the first side plate 12. The second mounting member 20 includes a second side plate 21, which is connected to the other side of the first bottom plate 11 along the Z direction (such as Figure 3The second mounting member 20 and the first mounting member 10 form a receiving groove 30, and the first taillight 201 is at least partially received in the receiving groove 30. In this embodiment, the receiving groove 30 extends from the vehicle 300 along the X direction from the front to the rear.

[0051] In the taillight mounting structure 100 of this embodiment, the first mounting member 10 and the second mounting member 20 can be formed separately, and then connected and assembled by welding, clamping or other forms. The molding and processing of the first mounting member 10 and the second mounting member 20 are both relatively convenient, which is conducive to obtaining the accommodating groove 30 adapted to the shape design requirements of the first taillight 201, reducing the restrictions on the shape design of the first taillight 201 due to the structural processing technology restrictions of the taillight mounting structure 100, and is conducive to obtaining a taillight with a better appearance effect. At the same time, by setting the second side plate 21 and the first mounting member 10 separately, the first mounting member 10 can be easily bent to obtain a first side plate 12 with a larger size along the Y direction. In this way, in combination with the use of the second side plate 21 with a larger size along the Y direction, a accommodating groove 30 with a larger recessed depth along the Y direction can be obtained, so that the Y-direction space can be fully utilized to accommodate the structure of the first taillight 201, thereby better meeting the installation space requirements of the slender first taillight 201.

[0052] The slenderness in the aforementioned slender first taillight 201 means that the size of the first taillight 201 along the X direction is larger, and the size along the Y direction is smaller. For example, the ratio of the size of the first taillight 201 along the X direction to the size of the first taillight 201 along the Y direction is greater than or equal to 1.5, and the ratio can be 1.5, 2, 2.5, 3, 3.5 or greater than 3.5. The ratio can be appropriately adjusted according to the actual shape requirements of the first taillight 201 and the molding process requirements of the taillight mounting structure 100.

[0053] See also Figure 6 and Figure 7 In this embodiment, the second side plate 21 is inclined relative to the first side plate 12, and the inclination direction is that the end of the second side plate 21 away from the first bottom plate 11 is inclined toward the direction away from the first side plate 12. Among them, the angle between the second side plate 21 and the plane perpendicular to the Z direction (defined as the first plane M1) is α, and α≤10°. In this embodiment, α can be set to any one of 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9° or 10°. For example, α can be set to the limit angle of the draft angle of the second side plate 21 of the second mounting member 20 (such as 3°)

[0054] Compared with the known taillight installation structure with a larger tilt angle, in this embodiment, the second side plate 21 is tilted at an angle α≤10°, which can ensure that when the first taillight 201 has an equal luminous area, the receiving groove 30 can provide a larger installation space to accommodate the first taillight 201. The luminous area refers to the area of ​​the first taillight 201 exposed on the outer surface of the vehicle 300, which is the area of ​​the first taillight 201 exposed on the outer surface of the vehicle 300 and the opening of the receiving groove 30 along the Y direction (defined as the first opening 32, also see Figure 5 ) are positively correlated with the size at .

[0055] In some known technologies, the side walls and bottom wall of the taillight receiving groove are an integrally formed part. Due to the limitations of stamping and other processing techniques, the side wall plate defining the taillight receiving groove requires a larger draft angle, resulting in a smaller space in the receiving groove under the same luminous area.

[0056] In this embodiment, the first taillight 201 and the taillight mounting structure 100 can be connected by various connection methods such as snap connection, pin connection, welding, thread connection, etc. The connection method between the first taillight 201 and the taillight mounting structure 100 can be adjusted according to actual needs, and this embodiment does not specifically limit it.

[0057] In this embodiment, see Figure 8 In the front direction of the vehicle 300 (i.e., the front in the X direction), the first side plate 12 and the second side plate 21 are connected to each other, and in the rear direction of the vehicle 300 (i.e., the rear in the X direction), the first side plate 12 and the second side plate 21 are spaced apart from each other, so that the accommodating groove 30 is open in the rear in the X direction. The open shape here refers to the accommodating groove 30 having a second opening 31 (also seen in Figure 5 ) and is not enclosed by the first mounting member 10 or the second mounting member 20. In this way, the first tail light 201 can be partially extended backward along the X direction, so as to increase the X-direction dimension of the first tail light 201 by using the space outside the accommodating groove 30, so that the first tail light 201 can be set to be more slender.

[0058] See also Figure 8 and Fig. 9 In this embodiment, the first bottom plate 11 includes a first sub-bottom plate segment 111 and a second sub-bottom plate segment 112, and the first side plate 12 includes a first sub-side plate segment 121 and a second sub-side plate segment 122. The first sub-side plate segment 121 is integrally bent and connected to the first sub-bottom plate segment 111. The second sub-side plate segment 122 is integrally bent and connected to the second sub-bottom plate segment 112. The integral bending mentioned here means that the two parts are formed by bending the same plate material. The first sub-side plate segment 121 and the second sub-side plate segment 122 can be connected by welding or the like to form the first side plate 12, and the first sub-bottom plate segment 111 and the second sub-bottom plate segment 112 can be connected by welding or the like to form the first bottom plate 11.

[0059] In this embodiment, see Fig. 9 The first bottom plate 11 further includes a first welding edge 113, and the first side plate 12 further includes a second welding edge 123. The first welding edge 113 is bent and connected to a side of the second sub-bottom plate segment 112 close to the first sub-bottom plate segment 111 along the X direction, and is bent inward along the Y direction. The first sub-bottom plate segment 111 overlaps the first welding edge 113 and is welded to the first welding edge 113. The welding method at this point can be cold metal transition welding, or other welding methods.

[0060] The second welding edge 123 is bent and connected to a side of the second sub-side plate segment 122 close to the first sub-side plate segment 121 along the X direction, and is bent inwardly along the Y direction. The first sub-side plate segment 121 is overlapped with the second welding edge 123 and welded to the second welding edge 123. The welding method at this point can be cold metal transition welding or other welding methods.

[0061] See also Figure 8 and Fig. 9 In this embodiment, the second mounting member 20 further includes an extension section 22, which is connected to the rear of the second side plate 21 along the X direction of the vehicle 300 and extends out of the first mounting member 10. The extension section 22 is used to cooperate with the portion of the first taillight 201 extending beyond the receiving groove 30.

[0062] The extension section 22 allows the portion of the first tail light 201 that extends beyond the receiving groove 30 along the X-direction to be supported and connected, thereby further increasing the length of the first tail light 201 along the X-direction and further achieving a slender shape of the first tail light 201 .

[0063] In this embodiment, see Figure 8 and Fig. 9 The first mounting member 10 further includes a first connecting edge 13. The second mounting member 20 further includes a second connecting edge 23, which is bent and connected to one side of the second side plate 21. A portion of the second connecting edge 23 is welded to the first connecting edge 13.

[0064] For the convenience of description, the length direction of the first connecting edge 13 is defined as the extension direction of the first connecting edge 13 in the X direction, and the width direction of the first connecting edge 13 is defined as the extension direction of the first connecting edge 13 in the Z direction; the length direction of the second connecting edge 23 is defined as the extension direction of the second connecting edge 23 in the X direction, and the width direction of the second connecting edge 23 is defined as the extension direction of the second connecting edge 23 in the Z direction.

[0065] See also Figure 8 and Fig. 9The first connection edge 13 includes a first welding section 131 and a first sealing section 132, and the second connection edge 23 includes a second welding section 231 and a second sealing section 232. The width of the first welding section 131 is greater than the width of the first sealing section 132, and the width of the second welding section 231 is greater than the width of the second sealing section 232. The first welding section 131 is attached to the second welding section 231 and welded to each other. The first sealing section 132 and the second sealing section 232 are spaced apart, and there is a first gap G1 (see FIG. Figure 7 ), the first gap G1 is filled with a sealant (not shown in the figure) to improve the sealing performance of the taillight mounting structure 100. The sealant can be filled from the side of the taillight mounting structure 100 close to the side panel structure 202 along the X direction.

[0066] The structural design of different widths of the first welding section 131 and the first sealing section 132 can further ensure that the first connecting edge 13 will not wrinkle during the bending and stamping process, ensuring the structural reliability of the first connecting edge 13. The structural design of different widths of the second welding section 231 and the second sealing section 232 can further ensure that the second connecting edge 23 will not wrinkle during the bending and stamping process, ensuring the structural reliability of the second connecting edge 23.

[0067] In this embodiment, see Figure 8 , the width of the first welding section 131 is similar to the width of the second welding section 231, and the width of the first sealing section 132 is similar to the width of the second sealing section 232. The width W1 of the first welding section 131 is between 14 mm and 20 mm. For example, the width W1 of the first welding section 131 can be set to any one of 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, and 20 mm. The width W1 of the first welding section 131 is preferably greater than or equal to 15 mm. The width W2 of the second welding section 231 is between 14 mm and 20 mm. For example, the width W2 of the second welding section 231 can be set to any one of 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, and 20 mm. The width W2 of the second welding section 231 is preferably greater than or equal to 15 mm.

[0068] The width W3 of the first sealing section 132 is greater than 1 mm, for example, the width W3 of the first sealing section 132 can be set to 1 mm, 1.5 mm, 2 mm, 3 mm, 4 mm, 5 mm, etc. The width W4 of the second sealing section 232 is greater than 1 mm, for example, the width W4 of the second sealing section 232 can be set to 1 mm, 1.5 mm, 2 mm, 3 mm, 4 mm, 5 mm, etc. The width H1 of the first gap G1 is greater than 1 mm, for example, the width H1 of the first gap G1 can be set to 1 mm, 1.5 mm, 2 mm, 3 mm, 4 mm, 5 mm, etc.

[0069] Optionally, a welding seam glue may be coated on the welding joint between the first welding section 131 and the second welding section 231 to further improve the sealing reliability of the welding joint between the first welding section 131 and the second welding section 231 .

[0070] In this embodiment, see Figure 7 , and combined with reference Figure 3 and Figure 5 A fixing portion 2011 is provided on the upper surface of the first tail light 201 , and a tail light avoidance area A1 is provided on the second side plate 21 . The tail light avoidance area A1 is recessed in a direction away from the fixing portion 2011 along the Z direction.

[0071] The first taillight 201 includes a housing 2012 and a light emitting portion 2013. The fixing portion 2011 is disposed on the top surface of the housing 2012 and is used to fix the light emitting portion 2013 to the housing 2012. By providing the taillight avoidance area A1, the distance between the second side plate 21 and the housing 2012 can be made greater than the distance between the first connecting edge 13 and the housing 2012, thereby ensuring that the fixing portion 2011 will not interfere with the second side plate 21 when the first taillight 201 is installed. In addition, the taillight avoidance area A1 can also enhance the structural strength of the second side plate 21.

[0072] Optionally, the recessed depth of the taillight avoidance area A1 is greater than or equal to 2 mm. For example, the recessed depth may be set to 2 mm, 3 mm, 4 mm, etc.

[0073] See also Figure 3 In this embodiment, the rear body assembly 200 of the rear part of the vehicle 300 includes a side panel structure 202, a rear water trough structure 203, the aforementioned taillight mounting structure 100, and a first taillight 201. The rear water trough structure 203 and the side panel structure 202 are distributed along the Y direction, and the rear water trough structure 203 is connected to the side panel structure 202. The taillight mounting structure 100 is installed between the side panel structure 202 and the rear water trough structure 203. The first taillight 201 is installed in the receiving groove 30 of the taillight mounting structure 100.

[0074] Since the vehicle body rear assembly 200 includes the taillight mounting structure 100 of the aforementioned embodiment, it has the beneficial effects of the taillight mounting structure 100 of the aforementioned embodiment, which will not be described in detail herein.

[0075] See also Figures 10 to 12In this embodiment, the side panel structure 202 includes a side panel 2021 and a first bending edge 2022. The first bending edge 2022 is bent and connected to the side panel 2021. The first bending edge 2022 is bent toward the second side panel 21. The second side panel 21 of the second mounting member 20 of the taillight mounting structure 100 is placed on the upper surface of the first bending edge 2022 and is welded to the first bending edge 2022. In this way, a stable connection between the second mounting member 20 and the side panel structure 202 can be achieved. The first bending edge 2022 and the second side panel 21 can be fixedly connected by cold metal transition welding and small spot welding. This welding method has a low requirement on the space between the first bending edge 2022 and the second side panel 21, so that the welding of the first bending edge 2022 and the second side panel 21 can be achieved in a smaller space range.

[0076] The surface of the first bent edge 2022 is parallel to the surface of the second side plate 21 to ensure the connection reliability between the second side plate 21 and the first bent edge 2022 .

[0077] In this embodiment, a second gap G2 is formed between the first bent edge 2022 and the upper side of the outer side surface of the first tail light 201 along the Z direction (see Figure 7 ), the width H2 of the second gap G2 is ≥1 mm. For example, the width H2 of the second gap G2 can be set to 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, etc. to ensure the lighting effect of the first taillight 201.

[0078] In this embodiment, the first bending edge 2022 includes a third welding section 20221 and a third sealing section 20222. The third welding section 20221 and the third sealing section 20222 are connected to each other, and the third sealing section 20222 is located at the rear end of the third welding section 20221 along the X direction. The third welding section 20221 is welded to the second side plate 21, and the third sealing section 20222 is sealed to the second side plate 21 by a sealant or other structure. Welding glue can also be additionally applied at the seam between the third welding section 20221 and the second side plate 21 to ensure the reliability of the connection and sealing between the third welding section 20221 and the second side plate 21.

[0079] By setting the third sealing section 20222, it can be ensured that during the process of processing the side panel 2021 to form the first bending edge 2022, the first bending edge 2022 will not wrinkle, thereby ensuring the structural reliability of the second bending edge 2023, further improving the welding reliability of the first bending edge 2022 and the second side panel 21, improving the strength of the welding structure, and reducing the possibility of abnormal noise.

[0080] The bending extension direction of the first bending edge 2022 is the width direction of the first bending edge 2022. The width W5 of the third welding section 20221 is ≥20 mm, for example, the width W5 of the third welding section 20221 can be 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, etc. The width W6 of the third sealing section 20222 is ≥1 mm, for example, the width W6 of the third sealing section 20222 can be 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm or 1.8 mm, etc.

[0081] Optionally, another third sealing section 20222 may also be additionally provided at one end of the third welding section 20221 facing forward along the X direction.

[0082] In this embodiment, see Fig.11 The side panel 2021 includes a panel body 20211 and an extension section 20212. The extension section 20212 is connected to the panel body 20211, and the extension section 20212 extends backward along the X direction. The first bent edge 2022 is bent and connected to a side of the extension section 20212 that is downward along the Z direction.

[0083] Optionally, the outer surface of the extension section 20212 is smoothly connected to the outer surface (i.e., the light-emitting surface) of the first taillight 201 (as can be seen in FIG. Figure 2 or Figure 4 ), and are all part of the exterior surface of the vehicle 300, so that the aesthetics of the rear vehicle body assembly 200 can be further improved.

[0084] See also Fig.13 and Fig.14 In this embodiment, the rear water flow trough structure 203 includes a trough body 2031 and a connecting piece 2032. The trough body 2031 includes a bottom wall 20311 and two side walls 20312. The two side walls 20312 are connected to the two sides of the bottom wall 20311 along the Y direction. The two side walls 20312 and the bottom wall 20311 form a water flow trough 20313. The connecting piece 2032 is fixedly connected to the side wall 20312 on the outer side of the trough body 2031 along the X direction. The first mounting member 10 of the taillight mounting structure 100 also includes an extension plate 14, which is connected to the rear side of the first bottom plate 11 along the X direction and the rear side of the first side plate 12 along the X direction. The extension plate 14 is transitionally connected to the bottom wall 20311 of the trough body 2031.

[0085] The second mounting member 20 of the taillight mounting structure 100 further includes a fixing plate 24 , which is bent and connected to the inner side of the extension section 22 along the Y direction of the vehicle 300 . The fixing plate 24 and the connecting plate 2032 are distributed along the Z direction of the vehicle 300 , and the fixing plate 24 and the connecting plate 2032 are connected.

[0086] Compared with the known side panel and taillight installation structure, the extension section 22, the fixing piece 24 and the connecting piece 2032 of this embodiment all extend backward from the first installation member 10 along the X direction, and the first taillight 201 can be installed on the lower surface of the extension section 22. In this way, the installation space of the first taillight 201 along the X direction can be further extended, and the installation of the first taillight 201 with a longer length along the X direction can be achieved. At the same time, the mutual connection of the extension section 22, the fixing piece 24 and the connecting piece 2032 can further ensure the overall stability of the rear vehicle body assembly 200.

[0087] In this embodiment, see Fig.13 and Fig.14 The fixing plate 24 is provided with a first welding fold 251 on one side close to the connecting plate 2032 along the Z direction, and the first welding fold 251 is bent outward along the X direction. The connecting plate 2032 overlaps the side of the first welding fold 251 facing inward along the X direction and is welded to the first welding fold 251. In this way, the welding surface accuracy of the connecting plate 2032 and the fixing plate 24 can be further improved.

[0088] In this embodiment, see Fig.13 and Fig.14 The side panel structure 202 also includes a second bent edge 2023, which is bent and connected to the rear end of the extension section 20212 along the Y direction. The connecting piece 2032 extends to the side of the second bent edge 2023 facing outward along the Y direction, and is welded to the second bent edge 2023. The fixing piece 24 extends to the side of the second bent edge 2023 facing outward along the Y direction, and is welded to the second bent edge 2023. In this way, the connection areas of the second bent edge 2023, the fixing piece 24 and the connecting piece 2032 are all in the same plane, further strengthening the overall connection firmness of the second bent edge 2023, the fixing piece 24 and the connecting piece 2032, and improving the structural strength of the plane.

[0089] In this embodiment, see Fig.15 The free end of the second bending edge 2023 is tilted inwardly along the Y direction. On the cross section perpendicular to the Z direction, the second bending edge 2023 and the second plane M2 perpendicular to the Y direction have a second angle β, β≤10°, for example, the angle β can be set to any one of 3°, 4°, 5°, 6°, 7°, 8°, 9° or 10°.

[0090] The direction of the second bending edge 2023 away from the extending section 20212 is the width direction of the second bending edge 2023 .

[0091] In this embodiment, see Fig.13The second bending edge 2023 includes a fourth welding section 20231 and a fourth sealing section 20232, and the width W7 of the fourth welding section 20231 is greater than the width W8 of the fourth sealing section 20232. The fourth sealing section 20232 is connected to one end of the fourth welding section 20231 close to the extension section 20212, and a sealant can be filled between the fourth sealing section 20232 and the fixing plate 24 to achieve sealing. Through the setting of the fourth sealing section 20232, it can be ensured that in the process of forming the second bending edge 2023 by processing the extension section 20212, the second bending edge 2023 will not have a wrinkling problem, thereby ensuring the structural reliability of the second bending edge 2023, further improving the welding reliability of the second bending edge 2023 with the fixing plate 24 and the connecting plate 2032, improving the strength of the welding structure, and reducing the possibility of abnormal noise.

[0092] Optionally, another fourth sealing section 20232 may also be additionally provided at the other end of the fourth welding section 20231 away from the extending section 20212 .

[0093] In this embodiment, see Fig.13 and Fig.14 A second welding fold 252 is provided on one side of the fixing sheet 24 close to the second bending edge 2023, and the second welding fold 252 is bent outwardly along the Y direction. A third welding fold 2033 is provided on one side of the connecting sheet 2032 close to the second bending edge 2023, and the third welding fold 2033 is bent outwardly along the Y direction. In this way, the welding surface accuracy between the fixing sheet 24 and the second bending edge 2023 can be improved, and the welding surface accuracy between the connecting sheet 2032 and the second bending edge 2023 can be improved.

[0094] In this embodiment, see Fig.14 The third welded folded edge 2033 is also provided with a guide protrusion 2034, which extends along the X direction toward the connection between the extension section 20212 and the second bent edge 2023. The guide protrusion 2034 can guide the connecting piece 2032 during the upper assembly process between the connecting piece 2032 and the second bent edge 2023, thereby guiding the connecting piece 2032 to cooperate with the X-direction outer side of the second bent edge 2023, and playing a role in fixing and positioning the connecting piece 2032 and the side panel structure 202. There are two guide protrusions 2034, and the two guide protrusions 2034 are arranged at intervals on the third welded folded edge 2033. The two guide protrusions 2034 can further improve the assembly accuracy of the connecting piece 2032, further reduce the risk of upper piece interference, and improve assembly accuracy and assembly reliability.

[0095] Optionally, the two guide protrusions 2034 are spaced apart, and the extension directions of the two guide protrusions 2034 are different from each other. In other embodiments, a plurality of guide protrusions 2034 may be provided, which is not specifically limited in this embodiment.

[0096] In this embodiment, see Fig.15 The rear body assembly 200 further includes a taillight decorative plate 204, which is connected to the first taillight 201. The taillight decorative plate 204 is covered on the inner side of the fixing plate 24 along the Y direction of the vehicle 300. The taillight decorative plate 204 is fixed to the connecting plate 2032.

[0097] The portion of the fixing plate 24 near the extension section 22 is provided with a track avoidance area A2, which is concave outward along the Y direction. The track avoidance area A2 is used to avoid the motion track C of the second tail light 302 (see FIG. Fig.15 ). Since the spacing between the fixing plate 24 and the taillight decorative plate 204 is the same, the taillight decorative plate 204 can also be offset outward along the Y direction due to the existence of the track avoidance area A2. In this way, it can be ensured that when the rear door 301 is opened, the movement of the second taillight 302 and the door 301 will not interfere with the taillight decorative plate 204, thereby improving the protection of the rear vehicle body assembly 200. At the same time, the track avoidance area A2 can also improve the structural strength of the fixing plate 24.

[0098] Specifically, the trajectory avoidance area A2 is located within a range on the fixing plate 24 surrounded by the first welding fold 251 , the second welding fold 252 and the edge of the extension section 22 .
