[0043] Example 1
[0044] This embodiment provides a metal matching structure between a rear door and a side panel of a vehicle body, such as Figure 1-Figure 2 As shown, it includes a rear door assembly 1, a side panel 2, a rear wheel eyebrow guard plate 3 and a rear door wheel cover sealing strip 4.
[0045] like Figure 3-Figure 4 As shown, the rear door assembly 1 includes a rear door sheet metal 1-1 and door components such as a door lock installed on the rear door sheet metal. The rear door sheet metal 1-1 is rotatably connected to the side panel sheet metal 2 through a hinge mechanism 5 to realize the opening and closing of the rear door assembly. The door components can be made of existing technology and will not be described in detail here. The rear door sheet metal 1-1 is fixed with a rear wheel eyebrow guard plate 3 on the outer side surface corresponding to the rear wheel eyebrow, as shown in FIG. Figure 5-Figure 6 As shown, the rear wheel eyebrow guard plate 3 includes an arc-shaped portion 3-1 and a straight portion 3-2 integrally arranged at one end of the arc-shaped portion 3-1, the arc-shaped portion 3-1 matches the shape of the rear wheel eyebrow and is fixed at the edge of the rear door sheet metal 1-1 corresponding to the rear wheel eyebrow, and the straight portion 3-2 matches the bottom edge of the rear door sheet metal 1-1 and is fixed at the bottom edge of the rear door sheet metal 1-1.
[0046] The rear wheel eyebrow guard plate 3 is detachably fixedly connected to the outer side surface of the rear door sheet metal 1-1. Preferably, the rear wheel eyebrow guard plate is detachably fixedly connected to the outer side surface of the rear door sheet metal 1-1 via a plurality of buckles 3-3. The buckles can be existing components and are not described in detail here.
[0047] Preferably, the rear wheel eyebrow guard plate 3 is fixed to the outer side surface of the rear door sheet metal 1-1 by 20 buckles 3-3.
[0048] like Figure 7-Figure 8 As shown, a rear door wheel cover sealing strip 4 is fixed to the inner side surface of the rear door sheet metal 1-1 at the position corresponding to the rear wheel fender. The rear door wheel cover sealing strip 4 is an arc-shaped sealing strip that matches the shape of the rear wheel fender. Preferably, the rear door wheel cover sealing strip 4 is made of EPDM material.
[0049] The rear wheel cover sealing strip 4 is detachably fixedly connected to the rear door sheet metal 1-1 through a plurality of buckles 4-1. The buckles can be existing components and will not be described in detail here. Preferably, the rear wheel cover sealing strip 4 is installed on the inner side of the rear door sheet metal 1-1 through 13 buckles 4-1.
[0050] When the rear door is in a closed state, the rear door wheel housing sealing strip 4 can fit with the side panel 2 .
[0051] like Figure 9-10 As shown, the hinge mechanism 5 includes a body connecting component 5-1 and a rear door connecting component 5-2. The body connecting component 5-1 is fixedly connected to the side panel sheet 2 by bolts, and the rear door connecting component 5-2 is fixedly connected to the rear door panel sheet 1-1 by bolts. The body connecting component 5-1 and the rear door connecting component 5-2 are rotatably connected by a pin shaft 5-3 so that the rear door panel sheet 1-1 and the side panel sheet metal 2 are rotatably connected.
[0052] The above technology can adopt the current automobile rear wheel and body side panel metal matching structure, and its further technical details are not described in detail here. When the vehicle is in driving state, the rear door panel metal and the side panel metal matching mode include Y-direction horizontal (car width direction) and Z-direction vertical (representing vehicle height direction). Any of the above states will directly cause continuous friction between the rear door wheel cover sealing strip 4 and the side panel metal 2. After a long period of friction, the paint layer on the side panel metal 2 will fall off, and the exposed side panel metal substrate will be rusted after falling off. This problem will seriously reduce the user's experience.
[0053] Therefore, this embodiment is improved on the basis of the current automobile rear door and body side metal matching structure, such as Figure 2 , Figure 11-13As shown, a rear wheel eyebrow decorative panel 6 is added to the edge of the side panel 2 at the rear wheel eyebrow position. The rear wheel eyebrow decorative panel 6 is made of non-metallic material, for example, the rear wheel eyebrow decorative panel 6 is made of plastic material. The rear wheel eyebrow decorative panel 6 adopts an arc structure that matches the rear wheel eyebrow position. When the rear door is closed, the rear door wheel cover sealing strip 4 contacts the outer side of the rear wheel eyebrow decorative panel 6. After contact, the rear wheel cover sealing strip 4 is compressed and deformed, so that the rear wheel cover sealing strip 4 and the rear wheel eyebrow decorative panel 6 are sealed and fitted, thereby preventing mud and sand from intruding into the wheel cover area and entering the rear door hole area to affect customer use.
[0054] At the same time, the rear wheel eyebrow decorative panel 6 is made of non-metallic material, changing from the traditional combination of metal parts and non-metallic parts to the combination of non-metallic parts and non-metallic parts. Under the premise of meeting other shape and sealing requirements, it can completely avoid the occurrence of paint grinding and rust problems on the side panel metal, improve the user experience and reduce the later maintenance cost of the vehicle.
[0055] Furthermore, the cross-section of the rear wheel eyebrow decorative panel 6 adopts a U-shaped structure, including an outer panel portion, an inner panel portion and a connecting portion connected between the outer panel portion and the inner panel portion, wherein the outer panel portion is the inner arc edge portion of the arc structure of the rear wheel eyebrow decorative panel 6, and the inner panel portion is the outer arc portion of the arc structure, wherein the connecting portion is detachably and fixedly connected to the outer side surface of the side panel 2. Preferably, the connecting portion is fixedly connected to the side panel 2 by a plurality of buckles 6-1, and the buckles can be existing components, which will not be described in detail herein.
[0056] Preferably, the rear wheel eyebrow decorative plate 6 is fixedly connected to the outer side surface of the side panel 2 via seven buckles 6 - 1 .
[0057] The outer plate portion is distributed along the edge of the side panel sheet 2 at the corresponding position of the rear wheel fender, wherein the outer plate portion and the edge of the side panel sheet 2 at the rear wheel fender position have a set gap, so that a gap fit is formed between the outer plate portion and the edge of the side panel sheet 2. With this arrangement, on the one hand, when the rear wheel fender decorative plate 6 is matched with the side panel sheet 2, only the outer end surface of the inner plate portion is the matching surface with the side panel sheet 2, which can reduce the difficulty of assembly during the production process and the difficulty of processing the rear wheel fender decorative plate 6. On the other hand, the reserved gap can prevent mixtures such as mud and sand from being sandwiched therein. Even if there is a small amount of mud and sand, it can be easily washed away when the vehicle is washed, thereby improving the durability of the vehicle.
[0058] In this embodiment, the cross-section of the rear wheel eyebrow decorative panel 6 is U-shaped, which can reduce the weight of the rear wheel eyebrow decorative panel 6 on the one hand, and reduce the area of the mating surface with the side panel 2 on the other hand, making it more convenient to assemble the rear wheel eyebrow decorative panel 6 on the side panel 2.
[0059] The remaining structures of the automobile rear wheel fender sealing structure of this embodiment can be based on the existing technology and will not be described in detail here.
[0060] The matching structure of the automobile rear door and the side panel of the vehicle body in this embodiment is improved on the basis of the current matching structure of the rear door and the side panel of the vehicle body, and only a rear wheel eyebrow decorative plate 6 made of non-metallic material is added. Through the various designs between the above structures, while meeting the requirements of modeling, assembly and sealing, the rust problem caused by the paint layer falling off under repeated friction of the side panel 2 is avoided, the user experience is further improved, the maintenance cost of the automobile in the later stage is reduced, and the occurrence of after-sales claims is eliminated. The remaining parts of the sealing structure do not need to be improved, the modification is convenient, the cost is low, and it has good economic benefits.
[0061] Example 2
[0062] This embodiment provides a car, which is provided with the car rear door and body side panel matching structure described in Example 1. The remaining structures of the car can adopt the existing technology and will not be described in detail here.
[0063] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
