[0002] The rear wing, professionally called a spoiler, is part of the aerodynamic package of a car. The main function of the rear wing is to reduce the lift at the rear of the vehicle. If the lift at the rear of the vehicle is greater than the lift at the front of the vehicle, it will easily lead to oversteering of the vehicle, reduced rear wheel grip and poor high-speed stability.

[0003] Therefore, in order to improve the dynamic performance of the whole vehicle, more and more car models are beginning to meet the performance requirements of the whole vehicle through styling and various aerodynamic mechanisms. At present, for example, the electric rear wing currently in trend is generally driven by a motor and can be adjusted to different openings, which can better ensure the driving performance of the vehicle. Therefore, the application of electric rear wings in car models has also become the mainstream demand of more and more performance cars and coupes.

[0004] The electric rear wing is usually arranged in the upper part of the trunk at the rear of the vehicle and installed on the trunk door sheet metal. This position belongs to the wet area. When it rains or when washing the car, water needs to be drained out, and a drain pipe usually needs to be designed.

[0005] At present, the lower part of the drain pipe is generally fixed on the trunk door sheet metal. The trunk door sheet metal is generally provided with a mounting hole. The drain pipe needs to interfere with passing through the mounting hole so as to lead water to the outside of the vehicle. This mounting structure has the problem of difficult assembly, which increases the assembly time and assembly cost, and is easy to be improperly assembled. After the drain pipe is assembled, the drain pipe is convex relative to the outer surface of the trunk door sheet metal, resulting in poor refinement of the vehicle. Utility Model Content

[0054] Based on the above design concept, an exemplary structure of the drainage pipe fixing device 1 of this embodiment in the application state is as follows: Figures 1 to 4 As shown, the drain pipe fixing device 1 is mainly used to connect the lower part of the drain pipe 4 and fix the lower part of the drain pipe 4 on the rear door exterior panel assembly 2. The upper part of the drain pipe 4 is connected to the water collecting tank 5 so that the water in the water collecting tank 5 can flow to the outside of the vehicle through the drain pipe 4 and the drain pipe fixing device 1.

[0055] In order to better understand the drain pipe fixing device 1 of this embodiment, Figures 1 to 3 The structure of the rear part of the vehicle body is briefly described. The structure of the rear part of the vehicle body can refer to the existing structure or the structure of the present embodiment, which mainly includes the trunk door sheet metal assembly 3, the back door exterior panel assembly 2, the support frame 7, the rear wing 8, etc. Among them, the trunk door sheet metal assembly 3 is blocked at the rear open position of the trunk, the back door exterior panel assembly is installed at the rear lower part of the trunk door sheet metal assembly 3, and the support frame 7 is installed on the trunk door sheet metal assembly 3, which is arranged at the front upper part of the back door exterior panel assembly and is used to install the rear wing 8 and the driving device of the rear wing 8.

[0056] In terms of specific structure, the trunk door sheet metal assembly 3 mainly includes a trunk door sheet metal inner panel 301 and a trunk door sheet metal outer panel, which are buckled and connected, and the trunk door sheet metal inner panel 301 is arranged on the side facing the inside of the vehicle, and the trunk door sheet metal outer panel is arranged on the side facing the outside of the vehicle. The trunk door sheet metal outer panel includes an upper section 302 of the trunk door sheet metal outer panel and a lower section 303 of the trunk door sheet metal outer panel, which are arranged up and down and connected together, and are respectively connected to the trunk door sheet metal inner panel 301.

[0057] The tailgate outer panel assembly mainly includes an outer panel frame 201 and an outer panel body 202, wherein the outer panel body 202 and the outer panel frame 201 are both made of plastic material, and the outer panel frame 201 is located inside the outer panel body 202. On the vehicle, the outer panel frame 201 is located in front of the outer panel body 202. The structures of the support frame 7, the rear wing 8 and the rear wing 8 drive device can all refer to the existing structure.

[0058] In this embodiment, there are two groups of drainage components using the drain pipe fixing device 1. The two groups of drainage components are arranged at intervals in the left and right directions of the vehicle, and the two groups of drainage components are symmetrical about the center line in the width direction of the vehicle. Therefore, one group of drainage components is taken as an example for explanation below.

[0059] Reference Figures 5 to 7 As shown, the drain pipe fixing device 1 of this embodiment includes a mounting portion 101 and a connecting portion 102. The mounting portion 101 is used to mount the drain pipe fixing device 1 on the rear door exterior panel assembly 2. One end of the mounting portion 101 is provided with a plane 1011. When the drain pipe fixing device 1 is mounted on the rear door exterior panel assembly 2, the plane 1011 is coplanar with the outer side surface 2011 of the rear door exterior panel assembly 2.

One end of the drainage channel 1021 is used to communicate with the drain pipe 4. The other end of the drainage channel 1021 is located on the plane 1011 and communicates with the atmosphere.

[0060] In this embodiment, the drain pipe fixing device 1 can be installed on the tailgate exterior panel assembly 2. Compared with the existing structure in which the drain pipe 4 is inserted into the trunk door sheet metal through interference fit, it is limited by the trunk door sheet metal structure being a thin plate structure made of metal and generally only able to process mounting holes to fix the drain pipe 4. Not only is it difficult to assemble, but the lower part of the drain pipe 4 will be exposed outside the trunk door sheet metal, making it difficult to meet the vehicle's requirements for refinement.

[0061] The drain pipe fixing device 1 is installed on the rear door exterior panel assembly 2 instead of the trunk door sheet metal. Since the rear door exterior panel assembly 2 is generally injection molded with plastic material, the structure of molding and installing the drain pipe fixing device 1 is relatively convenient, such as molding the following insertion groove 2013 in this embodiment, which is beneficial to ensure the appearance quality.

[0062] As a preferred embodiment, the mounting portion 101 is used to be detachably connected to the rear door exterior panel assembly 2, so that the drainage assembly can be easily disassembled. It is understandable that in addition to the detachable connection method, the mounting portion 101 and the rear door exterior panel assembly 2 can also be connected in a non-detachable manner, such as bonding.

[0063] As a preferred embodiment, an insertion slot 2013 is provided on the rear door exterior panel assembly 2, an opening 20131 is provided on one side of the insertion slot 2013, and the mounting portion 101 includes an insertion block provided on the drain pipe fixing device 1, and the insertion block is inserted into the insertion slot 2013 through the opening 20131.

[0064] In this structure, an insertion slot 2013 is provided on the rear exterior panel assembly 2, and the mounting portion 101 is inserted into the insertion slot 2013 through a side opening 20131 of the insertion slot 2013, which saves time and effort in assembly and can effectively save assembly time and cost.

[0065] In a preferred embodiment, a boss 2012 is provided at the edge of the outer panel frame 201 of the rear door outer panel assembly 2. The boss 2012 protrudes forward relative to the rear door outer panel assembly 2. The thickness of the boss 2012 is much thicker than that of the sheet metal. The thickness of the boss 2012 is along the left-right direction of the vehicle, and the length direction of the boss 2012 is along the height direction of the vehicle. The aforementioned insertion slot 2013 is provided on the boss 2012, and the opening 20131 of the insertion slot 2013 is located at the front side of the boss 2012.

[0066] As a preferred embodiment, a limiting structure is provided between the rear door exterior panel assembly 2 and the plug-in block, and the limiting structure is used to limit the plug-in block from escaping from the plug-in slot 2013. By providing the limiting structure, the reliability of the installation part 101 on the rear door exterior panel assembly 2 can be improved.

[0067] In a preferred embodiment, Figure 8 As shown, the limiting structure includes a limiting block arranged in the insertion slot 2013, and the insertion block is provided with a limiting slot. When the insertion block is inserted into the insertion slot 2013, the limiting block is inserted into the limiting slot to limit the movement of the insertion block in a direction orthogonal to its own insertion direction. Figure 8 In the state shown, the insertion direction is from the front to the rear of the vehicle, and the limit block is inserted into the limit slot to prevent the insertion block from being separated from the insertion slot 2013 along the left and right direction of the vehicle. The limit structure is set in this way, and the limit block and the limit slot cooperate, which also has the beneficial effect of smoothly guiding the installation block to be inserted into the correct installation position.

[0068] In a preferred embodiment, still refer to Figure 8 As shown, the limit block includes a first limit block 2014 and a second limit block 2015, and the first limit block 2014 is provided on the bottom wall of the insertion slot 2013, and the second limit block 2015 is provided on the side wall of at least one side of the insertion slot 2013. As in the present embodiment, the second limit blocks 2015 are provided on the side walls on both sides of the insertion slot 2013, and the two ends of the first limit block 2014 are respectively connected to the second limit blocks 2015 on the corresponding sides to improve the reliability of the limit and facilitate the smooth insertion of the insertion block into the insertion slot 2013.

[0069] And refer to Figures 5 to 7As shown, the aforementioned limiting grooves include a first limiting groove 1012 and a second limiting groove 1013 provided on the insertion block, the groove depths of the first limiting groove 1012 and the second limiting groove 1013 are preferably 3 mm, the first limiting groove 1012 is used to insert the first limiting block 2014, and the second limiting groove 1013 is used to insert the second limiting block 2015. Correspondingly, there are two second limiting grooves 1013 here, and the two second limiting grooves 1013 are connected with the first limiting groove 1012, so as to ensure that the insertion block is smoothly inserted into the correct position in the limiting groove, so as to ensure that the plane 1011 of the mounting portion 101 is coplanar with the outer side surface 2011 of the rear door outer trim assembly 2.

[0070] It should be explained here that, in this embodiment, the plane 1011 mentioned is arranged coplanar with the outer side surface 2011 of the rear door outer trim assembly 2, including absolute coplanarity and near coplanarity, that is, a certain installation error is allowed. Fig. 9 As shown, the plane 1011 is recessed by a certain distance relative to the outer side surface 2011, and the distance is preferably less than 1 mm, for example, it can be 0.2 mm, 0.5 mm and 0.07 mm, etc., so that the plane 1011 of the mounting portion 101 does not protrude outside the outer side surface 2011, thereby ensuring the exquisiteness of the fit.

[0071] In the above structure, the limit block includes a first limit block 2014 and a second limit block 2015, and the corresponding limit groove includes a first limit groove 1012 and a second limit groove 1013, which can further improve the reliability of the limit, thereby ensuring that the mounting portion 101 is firmly mounted on the rear door exterior panel assembly 2.

[0072] In addition, in the above structure, the limiting blocks may include one first limiting block 2014 and two second limiting blocks 2015, or any one or two of the three. The number and arrangement of the limiting blocks may also be changed or adjusted according to actual needs. For example, there may be four limiting blocks, some of which may be arranged on the bottom wall of the insertion slot 2013, some on the side wall of the insertion slot 2013, or all of which may be arranged on the bottom wall or the side wall of the insertion slot 2013.

[0073] As a preferred embodiment, along the direction orthogonal to the insertion direction of the plug-in block, the size of the limit block from the opening 20131 to the bottom wall of the plug-in slot 2013 gradually increases. In this embodiment, along the direction from the front of the vehicle to the rear of the vehicle, the size of the limit block in the left and right direction of the vehicle gradually increases, so as to facilitate the smooth insertion of the plug-in block into the installation slot. Here, the size of the limit block from the opening 20131 to the bottom wall of the plug-in slot 2013 is gradually increased, which has the effect of improving the installation reliability of the mounting portion 101 on the rear door exterior panel assembly 2.
