Description

Technical Field

[0001] The embodiments of the present application relate to the field of vehicle technology, and in particular to a taillight assembly, a rear vehicle body structure, and a vehicle. Background Art

[0002] The assembly of the vehicle's side taillights significantly impacts the clearance and flushness of the entire tailgate area. Furthermore, the clearance and flushness between the taillights, the side panels, and the tailgate taillights present significant challenges during vehicle assembly and adjustment. Existing assembly techniques typically utilize mounting in the vehicle's positive X or Y direction. This method, based on the coordinate axis, allows for narrow adjustments within the positive X and Y directions. This assembly method is particularly advantageous for adjusting square taillights.

[0003] However, for arc-shaped taillights, the clearance and flushness are affected by both the X and Y directions, making it difficult to adjust the clearance and flushness between the taillight and the side panel simply by adjusting the X and Y positions. Furthermore, for arc-shaped taillights, the outer A-surface forms a significant angle with both the X and Y directions. If the mounting points are arranged in the positive X or Y directions, the mounting points of the taillight mounting plate will have a significant angle with the main surface of the taillight plate, significantly increasing the difficulty of molding the taillight mounting plate. Furthermore, due to the large angle of the taillight mounting surface on the taillight mounting plate, a large draft angle is required, which increases the space required for the lamp installation.

[0040] Reference below Figures 1-6 The taillight assembly 10 provided in an embodiment of the present application is described.

[0041] In a first aspect, an embodiment of the present application provides a taillight assembly 10 , comprising: a taillight body 1 and a taillight mounting plate 2 .

[0042] Specifically, refer to Figures 1-6 The taillight assembly 10 is used for a vehicle, and the vehicle has a side outer panel 30, and the side outer panel 30 has a mounting groove 301. The taillight assembly 10 is suitable for being arranged in the mounting groove 301. In the present application, there are two mounting grooves 301 and they are respectively located on the left and right sides of the vehicle, but the present application is not limited to this. The two mounting grooves 301 can be both located on the rear side of the vehicle.

[0043] Furthermore, the taillight body 1 is positioned within the notch of the mounting slot 301 and has a first locating pin 11 facing the bottom wall of the mounting slot 301. The taillight mounting plate 2 is positioned within the mounting slot 301 and connected to the bottom wall of the mounting slot 301 (e.g., by welding). The taillight mounting plate 2 has a first locating hole 21 that mates with the first locating pin 11. The axis of the first locating hole 21 is parallel to the normal direction of the CAS (Concept A Surface) surface of the taillight body 1. The side outer panel 30 has a through-hole corresponding to the first locating hole 21. The first locating pin 11 can be inserted into the first locating hole 21 and the through-hole. The interaction between the first locating pin 11 and the first locating hole 21 allows the taillight body 1 and the taillight mounting plate 2 to be initially positioned, facilitating subsequent installation operations.

[0044] In addition, it should be noted that CAS surfaces refer to vehicle exterior styling surfaces created using computer-aided design technology in automotive design. They are primarily used in the vehicle exterior design phase to help designers quickly and accurately construct and modify the vehicle's surfaces and shapes.

[0045] It can be understood that the first positioning hole 21 is designed so that the axial direction of the first positioning hole 21 is parallel to the normal direction of the CAS surface of the taillight body 1, and the axis of the first positioning pin 11 is also parallel to the normal direction of the CAS surface of the taillight body 1, so that the taillight body 1 can be installed in the installation groove 301 along the normal direction of the CAS surface of the taillight body 1, so that the installation direction of the taillight body 1 is not based on the length and width directions of the vehicle as the installation direction, isolating the influence of the length and width directions of the vehicle on the installation direction of the taillight body 1, thereby reducing the gap surface difference between the taillight body 1 and the side outer panel 30, and at the same time facilitating the matching connection between the taillight body 1 and the taillight mounting plate 2, reducing the installation angle difference between the taillight mounting plate 2 and the taillight body 1, reducing the molding difficulty of the taillight mounting plate 2, and improving the utilization rate of the installation space (space in the mounting groove 301).

[0046] Furthermore, if Figure 2-Figure 4 As shown, the taillight mounting plate 2 has at least one first threaded hole 24, and the taillight body 1 has at least one corresponding threaded fastening portion. As a result, the taillight mounting plate 2 and the taillight body 1 are also connected by fasteners, thereby improving the reliability of the installation connection between the taillight mounting plate 2 and the taillight body 1.

[0047] For example, in the present application, there is one first threaded hole 24 , but the present application is not limited thereto. There may be more first threaded holes 24 , such as 2, 3, 4 or 5.

[0048] Furthermore, if Figure 2-Figure 4As shown, the side outer panel 30 is further provided with a water flow groove 302 , which is connected to the installation groove 301 , thereby facilitating the drainage of water from the installation groove 301 and improving the waterproof effect.

[0049] The taillight assembly 10 provided in the embodiment of the present application has a notch provided in the mounting groove 301 through the taillight body 1 and has a first positioning pin 11 facing the bottom wall of the mounting groove 301; the taillight mounting plate 2 is provided in the mounting groove 301 and connected to the bottom wall of the mounting groove 301, and the taillight mounting plate 2 has a first positioning hole 21 that matches the first positioning pin 11. The axial direction of the first positioning hole 21 is parallel to the normal direction of the CAS surface of the taillight body 1, so that the taillight body 1 can be installed in the mounting groove along the normal direction of the CAS surface of the taillight body 1. In 301, the installation direction of the taillight body 1 is not based on the length and width directions of the vehicle, which isolates the influence of the length and width directions of the vehicle on the installation direction of the taillight body 1, thereby reducing the gap surface difference between the taillight body 1 and the side outer panel 30, and facilitating the matching connection between the taillight body 1 and the taillight mounting plate 2, reducing the installation angle difference between the taillight mounting plate 2 and the taillight body 1, reducing the molding difficulty of the taillight mounting plate 2, and improving the utilization rate of the installation space (the space in the installation groove 301).

[0050] In a possible implementation of the present application, Figure 2-Figure 4 As shown, the taillight body 1 has a first mounting portion (not shown), and the taillight mounting plate 2 further has a first mounting hole 22 that cooperates with the first mounting portion. The axis direction of the first mounting hole 22 is parallel to the normal direction of the CAS surface of the taillight body 1. It should be noted that the first mounting portion can be a buckle, and the first mounting hole 22 can be a locking hole that cooperates with the buckle.

[0051] It can be understood that the interaction between the first mounting portion and the first mounting hole 22 further enhances the connection reliability between the taillight mounting plate 2 and the taillight body 1. The axial direction of the first mounting hole 22 is parallel to the normal direction of the CAS surface of the taillight body 1. Simultaneously, the axial direction of the first mounting portion is parallel to the normal direction of the CAS surface of the taillight body 1. This further isolates the influence of the vehicle's length and width on the installation direction of the taillight body 1, reduces the gap and surface difference between the taillight body 1 and the side outer panel 30, and reduces the installation angle difference between the taillight mounting plate 2 and the taillight body 1. This reduces the difficulty of molding the taillight mounting plate 2 and improves the utilization of the installation space.

[0052] In a possible implementation of the present application, Figure 2-Figure 4As shown, there are multiple first mounting holes 22, and the first mounting parts are multiple and correspond one to one with the multiple first mounting holes 22. The multiple first mounting holes 22 are spaced apart in the depth direction of the mounting groove 301 (for example, along the width direction of the vehicle in this application), and any first mounting hole 22 and the first positioning hole 21 are spaced apart in the depth direction of the mounting groove 301.

[0053] For example, in the present application, there are two first mounting holes 22 and two first mounting parts, but the present application is not limited to this. There can be more first mounting holes 22 and multiple first mounting parts in a one-to-one correspondence, such as 3, 4, 5 or 6.

[0054] It is understood that when the taillight mounting plate 2 and the taillight body 1 are being installed, different first mounting portions on the taillight body 1 can be mated with corresponding first mounting holes 22 on the taillight mounting plate 2, thereby achieving the desired positioning between the taillight mounting plate 2 and the taillight body 1. Furthermore, since the multiple first mounting holes 22 are spaced apart in the depth direction of the mounting groove 301 (e.g., along the width direction of the vehicle in this application), any one of the first mounting holes 22 is spaced apart from the first positioning hole 21 in the depth direction of the mounting groove 301. This allows the taillight body 1 to be adjusted and positioned in the depth direction of the mounting groove 301 during installation of the taillight mounting plate 2 and the taillight body 1, thereby facilitating reduction of the clearance difference between the taillight body 1 and surrounding structures, such as the side panel 30, in the depth direction of the mounting groove 301.

[0055] The first mounting portion is foldably or retractably provided on the taillight body 1 , thereby avoiding mutual interference between different first mounting portions during installation, and allowing the taillight mounting plate 2 and the taillight body 1 to be installed smoothly.

[0056] In one possible implementation of the present application, the side of the taillight mounting plate 2 facing away from the bottom wall of the mounting groove 301 is parallel to the CAS surface of the taillight body 1. This further facilitates the mating connection between the taillight body 1 and the taillight mounting plate 2, reduces the installation angle difference between the taillight mounting plate 2 and the taillight body 1, reduces the difficulty in molding the taillight mounting plate 2, and improves the utilization rate of the installation space (the space within the mounting groove 301).

[0057] Reference below Figures 1-6 The vehicle body rear structure 100 provided in an embodiment of the present application is described.

[0058] like Figures 1-6 As shown, in the second aspect, an embodiment of the present application provides a vehicle body rear structure 100 , including: a side outer panel 30 , the above-mentioned taillight assembly 10 , a rear bumper 201 and a rear bumper mounting bracket 202 .

[0059] Specifically, refer to Figures 1-6The side outer panel 30 has a mounting groove 301; the rear bumper mounting bracket 202 is arranged in the mounting groove 301 and has a second positioning pin 203 extending toward the bottom wall of the mounting groove 301; the rear bumper 201 is arranged at the notch of the mounting groove 301 and is connected to the rear bumper mounting bracket 202; the taillight mounting plate 2 has a boss 23 on the side away from the bottom wall of the mounting groove 301, and the boss 23 is provided with a second positioning hole 231 that cooperates with the second positioning pin 203; the axis of the second positioning hole 231 is parallel to the normal direction of the CAS surface of the rear bumper 201.

[0060] It should be noted that the rear bumper 201 and the rear bumper mounting bracket 202 are arranged on the lower side of the taillight assembly 10. In the present application, there are two mounting grooves 301, which are respectively located on the left and right sides of the vehicle, and the boss 23 extends along the length direction of the vehicle; however, the present application is not limited to this. When the two mounting grooves 301 can be located on the rear side of the vehicle, the boss 23 extends along the width direction of the vehicle.

[0061] It can be understood that the setting of the boss 23 facilitates the installation of the rear guard mounting bracket 202 on the taillight mounting plate 2. Since the rear guard mounting bracket 202 is installed on the taillight mounting plate 2, the taillight body 1 is also installed on the taillight mounting plate 2, thereby reducing the mutual displacement between the rear guard mounting bracket 202, the taillight body 1 and the taillight mounting plate 2, making the installation between the rear guard mounting bracket 202, the taillight body 1 and the taillight mounting plate 2 more stable.

[0062] Further, if Figure 1-Figure 5 As shown, the axis of the second positioning hole 231 is parallel to the normal direction of the CAS surface of the rear bumper 201, and the axis of the second positioning pin 203 is also parallel to the normal direction of the CAS surface of the rear bumper 201, so that the rear bumper 201 and the rear bumper mounting bracket 202 can be installed in the mounting groove 301 along the normal direction of the CAS surface of the rear bumper 201, so that the installation direction of the rear bumper 201 and the rear bumper mounting bracket 202 is not based on the length and width directions of the vehicle as the installation direction, avoiding the influence of the length and width directions of the vehicle on the installation direction of the rear bumper 201 and the rear bumper mounting bracket 202, thereby reducing the gap surface difference between the rear bumper 201 and the side outer panel 30.

[0063] Further, if Figure 2 and Figure 4As shown, the boss 23 has at least one second threaded hole 234 and at least one third threaded hole 235. The second threaded hole 234 enables the rear bumper mounting bracket 202, the taillight body 1, and the taillight mounting plate 2 to be connected via fasteners, thereby further improving the connection reliability between the rear bumper mounting bracket 202, the taillight body 1, and the taillight mounting plate 2. The third threaded hole 235 is used to fasten the taillight body 1 and the taillight mounting plate 2, thereby further improving the connection reliability between the taillight body 1 and the taillight mounting plate 2.

[0064] The rear vehicle body structure 100 provided in the embodiment of the present application is provided with the above-mentioned taillight assembly 10, wherein the taillight body 1 is provided in the notch of the mounting groove 301 and has a first positioning pin 11 facing the bottom wall of the mounting groove 301; the taillight mounting plate 2 is provided in the mounting groove 301 and connected to the bottom wall of the mounting groove 301, and the taillight mounting plate 2 has a first positioning hole 21 that matches the first positioning pin 11, and the axial direction of the first positioning hole 21 is parallel to the normal direction of the CAS surface of the taillight body 1, so that the taillight body 1 can be aligned along the normal direction of the CAS surface of the taillight body 1. The taillight body 1 is installed in the installation groove 301 in the direction of the vehicle, so that the installation direction of the taillight body 1 is not based on the length and width directions of the vehicle, and the influence of the length and width directions of the vehicle on the installation direction of the taillight body 1 is isolated, thereby reducing the gap surface difference between the taillight body 1 and the side outer panel 30, and facilitating the matching connection between the taillight body 1 and the taillight mounting plate 2, reducing the installation angle difference between the taillight mounting plate 2 and the taillight body 1, reducing the molding difficulty of the taillight mounting plate 2, and improving the utilization rate of the installation space (the space in the installation groove 301).

[0065] In a possible implementation of the present application, Figure 2-Figure 4 As shown, the side of the rear bumper mounting bracket 202 facing the bottom wall of the mounting groove 301 also has a third positioning pin and a fourth positioning pin, and the boss 23 has a third positioning hole 232 that cooperates with the third positioning pin, and the axis of the third positioning hole 232 is parallel to the normal direction of the CAS surface of the rear bumper 201.

[0066] It can be understood that through the mutual cooperation between the third positioning hole 232 and the third positioning pin, and then through the mutual cooperation between the second positioning hole 231 and the second positioning pin 203, the rear guard mounting bracket 202 can be prevented from rotating around the axial direction of the second positioning hole 231, thereby improving the installation stability of the rear guard mounting bracket 202 on the boss 23.

[0067] The axis of the third positioning hole 232 is parallel to the normal direction of the CAS surface of the rear bumper 201, thereby further enabling the rear bumper 201 and the rear bumper mounting bracket 202 to be installed in the mounting groove 301 along the normal direction of the CAS surface of the rear bumper 201, so that the installation direction of the rear bumper 201 and the rear bumper mounting bracket 202 is not based on the length and width directions of the vehicle, thereby avoiding the influence of the length and width directions of the vehicle on the installation direction of the rear bumper 201 and the rear bumper mounting bracket 202, thereby reducing the gap surface difference between the rear bumper 201 and the side outer panel 30.

[0068] Further, if Figure 2-Figure 4 As shown, the vehicle body rear structure 100 further includes: a rear bumper bracket fixing bracket 204 , which is connected to a side of the taillight mounting plate 2 away from the bottom wall of the mounting groove 301 and is provided at one end of the boss 23 in the length direction.

[0069] It can be understood that when the length of the boss 23 is not enough to install the rear protection mounting bracket 202, the length of the boss 23 is extended by setting the rear protection mounting bracket 204, thereby facilitating the installation of the rear protection mounting bracket 202 and improving the installation stability and reliability of the rear protection mounting bracket 202.

[0070] Further, if Figure 2-Figure 4 As shown, the rear bumper bracket fixing bracket 204 is provided with a fourth locating hole 2041 that cooperates with the fourth locating pin. The axis of the fourth locating hole 2041 is parallel to the normal direction of the CAS surface of the rear bumper 201. Thus, the mutual cooperation between the fourth locating hole 2041 and the fourth locating pin, the mutual cooperation between the third locating hole 232 and the third locating pin, and the mutual cooperation between the second locating hole 231 and the second locating pin 203 further prevents the rear bumper mounting bracket 202 from rotating about the axis of the second locating hole 231, thereby improving the installation stability of the rear bumper mounting bracket 202 on the boss 23.

[0071] The axis of the fourth positioning hole 2041 is parallel to the normal direction of the CAS surface of the rear bumper 201, thereby further enabling the rear bumper 201 and the rear bumper mounting bracket 202 to be installed in the mounting groove 301 along the normal direction of the CAS surface of the rear bumper 201, so that the installation direction of the rear bumper 201 and the rear bumper mounting bracket 202 is not based on the length and width directions of the vehicle, thereby avoiding the influence of the length and width directions of the vehicle on the installation direction of the rear bumper 201 and the rear bumper mounting bracket 202, thereby reducing the gap surface difference between the rear bumper 201 and the side outer panel 30.

[0072] In a possible implementation of the present application, Figure 2-Figure 4As shown, the third positioning hole 232 is a strip-shaped hole extending along the length of the boss 23. It is understood that the third positioning hole 232 is a strip-shaped hole extending along the length of the boss 23, so that the third positioning pin can be moved and adjusted in the third positioning hole 232, thereby facilitating the reduction of the tolerance between the rear guard mounting bracket 202 and the boss 23 during installation.

[0073] In a possible implementation of the present application, Figure 2-Figure 4 As shown, the fourth positioning hole 2041 is a strip-shaped hole extending along the length of the boss 23. It can be understood that the fourth positioning hole 2041 is a strip-shaped hole extending along the length of the boss 23, so that the fourth positioning pin can be moved and adjusted in the fourth positioning hole 2041, thereby facilitating the reduction of the tolerance during the installation of the rear guard mounting bracket 202 and the rear guard bracket fixing bracket 204.

[0074] In a possible implementation of the present application, Figure 2-Figure 4 As shown, along the length direction of the boss 23 , the second positioning hole 231 , the third positioning hole 232 and the fourth positioning hole 2041 are located on the same straight line, thereby facilitating the connection operation between the rear guard mounting bracket 202 , the rear guard bracket fixing bracket 204 and the boss 23 .

[0075] In a possible implementation of the present application, Figure 2-Figure 4 As shown, the second positioning hole 231, the third positioning hole 232 and the fourth positioning hole 2041 are aligned in the depth direction of the mounting groove 301. This facilitates the connection operation between the rear support mounting bracket 202, the rear support fixing bracket 204 and the boss 23.

[0076] In a possible implementation of the present application, Figure 2-Figure 4 As shown, the rear bumper mounting bracket 202 has a second mounting portion and a third mounting portion on one side facing the bottom wall of the mounting groove 301, and the boss 23 has a second mounting hole 233 that cooperates with the second mounting portion. The rear bumper bracket fixing bracket 204 is also provided with a third mounting hole 2042 that cooperates with the third mounting portion. The axes of the second mounting hole 233 and the third mounting hole 2042 are both parallel to the normal direction of the CAS surface of the rear bumper 201.

[0077] It should be noted that the second mounting portion and the third mounting portion may both be snap buckles, and the second mounting hole 233 and the third mounting hole 2042 may be corresponding snap holes.

[0078] It can be understood that the cooperation between the second mounting portion and the second mounting hole 233 , and the cooperation between the third mounting portion and the third mounting hole 2042 , further improves the installation stability and reliability of the rear guard mounting bracket 202 .

[0079] The axes of the second mounting hole 233 and the third mounting hole 2042 are both parallel to the normal direction of the CAS surface of the rear bumper 201, thereby further enabling the rear bumper 201 and the rear bumper mounting bracket 202 to be installed in the mounting groove 301 along the normal direction of the CAS surface of the rear bumper 201, so that the installation direction of the rear bumper 201 and the rear bumper mounting bracket 202 is not based on the length and width directions of the vehicle, thereby avoiding the influence of the length and width directions of the vehicle on the installation direction of the rear bumper 201 and the rear bumper mounting bracket 202, thereby reducing the gap surface difference between the rear bumper 201 and the side outer panel 30.

[0080] In a possible implementation of the present application, Figure 2-Figure 4 As shown, the second mounting hole 233 and the third mounting hole 2042 are spaced apart in the depth direction of the mounting groove 301 .

[0081] It is understood that when the rear bumper mounting bracket 202 is mounted to the boss 23, different second mounting portions on the rear bumper mounting bracket 202 can cooperate with corresponding second mounting holes 233 on the boss 23, thereby achieving positioning and mounting between the boss 23 and the rear bumper mounting bracket 202. Furthermore, because the plurality of second mounting holes 233 are spaced apart in the depth direction of the mounting slot 301 (e.g., along the width direction of the vehicle in this application), any second mounting hole 233 is spaced apart from the second positioning hole 231 in the depth direction of the mounting slot 301. This allows the rear bumper mounting bracket 202 and the rear bumper 201 to be adjusted and positioned in the depth direction of the mounting slot 301 when the rear bumper mounting bracket 202 is mounted to the boss 23, thereby facilitating reduction of the clearance and face difference between the rear bumper 201 and surrounding structures, such as the side outer panel 30, in the depth direction of the mounting slot 301.

[0082] The second mounting portion is foldably or retractably provided on the rear protection mounting bracket 202 , thereby avoiding mutual interference between different second mounting portions during installation, and allowing the rear protection mounting bracket 202 to be installed on the boss 23 smoothly.

[0083] When the rear bumper mounting bracket 202 is mounted to the rear bumper bracket fixing bracket 204, different third mounting portions on the rear bumper mounting bracket 202 can mate with corresponding third mounting holes 2042 on the rear bumper bracket fixing bracket 204, thereby achieving a positional mounting between the rear bumper bracket fixing bracket 204 and the rear bumper mounting bracket 202. Since the plurality of third mounting holes 2042 are spaced apart in the depth direction of the mounting slot 301 (e.g., along the width direction of the vehicle in this application), any third mounting hole 2042 is spaced apart from the third positioning hole 232 in the depth direction of the mounting slot 301. This allows the rear bumper mounting bracket 202 and the rear bumper 201 to be adjusted and positioned in the depth direction of the mounting slot 301 when the rear bumper mounting bracket 202 is mounted to the rear bumper bracket fixing bracket 204, thereby facilitating reducing the gap surface difference between the rear bumper 201 and surrounding structures such as the side outer panel 30 in the depth direction of the mounting slot 301.

[0084] Among them, the third mounting portion is foldable or retractable and is arranged on the rear protection mounting bracket 202, thereby avoiding mutual interference between different third mounting portions during installation, so that the rear protection mounting bracket 202 can be installed smoothly on the rear protection bracket fixing bracket 204.

[0085] Further, if Figure 2-Figure 4 As shown, the rear support bracket fixing bracket 204 extends obliquely from top to bottom toward the bottom wall of the mounting slot 301. It should be noted that the fourth positioning hole 2041 and the third mounting hole 2042 are located on the rear support bracket fixing bracket 204, while the second positioning hole 231 and the third positioning hole 232 are located on the boss 23 and are aligned in the depth direction of the mounting slot 301. However, the second positioning hole 231, the third positioning hole 232, and the fourth positioning hole 2041 are aligned in the depth direction of the mounting slot 301. By extending the rear support bracket fixing bracket 204 obliquely from top to bottom toward the bottom wall of the mounting slot 301, the second mounting hole 233 and the third mounting hole 2042 can be spaced apart in the depth direction of the mounting slot 301.

[0086] The vehicle provided in the embodiments of the present application is described below.

[0087] In a third aspect, an embodiment of the present application provides a vehicle comprising the aforementioned vehicle body rear structure 100 .

[0088] The vehicle provided in the embodiment of the present application is provided with the above-mentioned rear vehicle body structure 100 and the above-mentioned taillight assembly 10. The taillight body 1 is provided in the notch of the mounting groove 301 and has a first positioning pin 11 facing the bottom wall of the mounting groove 301; the taillight mounting plate 2 is provided in the mounting groove 301 and connected to the bottom wall of the mounting groove 301, and the taillight mounting plate 2 has a first positioning hole 21 that matches the first positioning pin 11. The axial direction of the first positioning hole 21 is parallel to the normal direction of the CAS surface of the taillight body 1, so that the taillight body 1 can be moved along the CAS surface of the taillight body 1. The normal direction of the surface is installed in the installation groove 301, so that the installation direction of the taillight body 1 is not based on the length and width directions of the vehicle, isolating the influence of the length and width directions of the vehicle on the installation direction of the taillight body 1, thereby reducing the gap surface difference between the taillight body 1 and the side outer panel 30, and facilitating the matching connection between the taillight body 1 and the taillight mounting plate 2, reducing the installation angle difference between the taillight mounting plate 2 and the taillight body 1, reducing the molding difficulty of the taillight mounting plate 2, and improving the utilization rate of the installation space (the space in the installation groove 301).
