[0031] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present invention. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0032] The first embodiment of the utility model provides a rear fender structure, such as Figure 1 As shown, the rear fender structure includes a fender body and a plurality of brackets installed on the inner side of the fender body 1, the plurality of brackets include a first bracket 2 arranged at the front of the fender body 1, a second bracket 3 arranged at the rear of the fender body 1 and a third bracket 4 arranged at the lower part of the fender body 1, the first bracket 2 is connected to the rear longitudinal beam 100 of the vehicle body, the second bracket 3 is connected to the vehicle body frame 200, and the third bracket 4 is respectively connected to the wheel cover and the vehicle body frame 200.

[0033] The inner side of the fender body 1 refers to the side facing the inside of the vehicle. Multiple brackets are arranged at different positions of the fender body 1, which improve the connection stability between the fender body 1 and the vehicle body when connected to different parts of the vehicle body. Specifically, the bracket includes a first bracket 2, a second bracket 3 and a third bracket 4. The first bracket 2, the second bracket 3 and the third bracket 4 are arranged at the front, rear and lower part of the fender body 1, respectively. The first bracket 2 is connected to the rear longitudinal beam 100 of the vehicle body, the second bracket 3 is connected to the vehicle body frame 200, and the third bracket 4 is connected to the wheel cover and the vehicle body frame 200, respectively. Integrating multiple brackets into the fender body 1 effectively reduces parts development, reduces production costs, and meets the requirements of the design of fewer parts. Connecting the fender body 1 to the vehicle body through multiple brackets has higher installation efficiency than connecting the fender body 1 to the vehicle body by spot welding.

[0034] The first bracket 2, the second bracket 3 and the third bracket 4 are respectively arranged at the front, rear and lower part of the fender body 1, so that different positions of the fender body 1 are connected to different parts of the vehicle body, and the stability of the connection between the fender body 1 and the vehicle body is improved. The first bracket 2, the second bracket 3 and the third bracket 4 are independently arranged to facilitate adjustment of their relative positions with the fender body 1 and the vehicle body.

[0035] like Figure 2 As shown, the first bracket 2 includes a first bracket body 21 and a plurality of legs 22. The first bracket body 21 is connected to the fender body 1. The legs 22 extend from the first bracket body 21 into the vehicle, and the legs 22 are connected to the rear longitudinal beam 100 of the vehicle body. The first bracket body 21 serves to improve the support strength between the front part of the fender body 1 and the rear longitudinal beam 100 of the vehicle body. The legs 22 are mainly used to connect with the rear longitudinal beam 100 of the vehicle body. For example, two legs 22 are provided, extending along the first bracket body 21 into the vehicle body to the longitudinal beam 100 of the vehicle body. The number of legs 22 can be adjusted as needed. The distance of the legs 22 extending into the vehicle body is adapted to the distance between the first bracket body 21 and the rear longitudinal beam 100 of the vehicle body. One end of the legs 22 close to the rear longitudinal beam 100 of the vehicle body is connected to the rear longitudinal beam 100 of the vehicle body through a fastener. The fastener is preferably a bolt. Each leg 22 is provided with a plurality of first mounting holes 23 for mounting bolts. Exemplarily, each support leg 22 is provided with two first mounting holes 23 , and the first bracket 2 and the rear longitudinal beam 100 of the vehicle body are connected via the support legs 22 and fasteners, so as to facilitate installation and disassembly.

[0036] The first bracket body 21 is triangular in shape. The triangular first bracket body 21 has higher stability. Exemplarily, the first bracket body 21 is formed by connecting a plurality of support rods, the support leg 22 is connected to at least one support rod, and each support rod and the support leg 22 have a cavity that arches toward the vehicle interior, and the cavity strengthens the rigidity of the rear longitudinal beam 100 of the vehicle body.

[0037] like Figure 3 As shown, the second bracket 3 is a plate-like component, and the upper and lower ends of the plate-like component are connected to the fender body 1 to form a third reinforcement cavity 31, and the plate body of the plate-like component is connected to the vehicle body frame 200. The second bracket 3 is set as a plate-like component, which can play a role of stable support for the fender body 1, and the second bracket 3 is only set as one, so as to achieve less parts. The third reinforcement cavity 31 formed between the second bracket 3 and the fender body 1 improves the energy absorption and collapse ability of the fender body 1. Specifically, the second bracket 3 is connected to the vehicle body frame 200 through the plate body of the plate-like component, so as to improve the stability of the connection between the fender body 1 and the vehicle body frame 200. The second bracket 3 and the vehicle body frame 200 can be connected through a connecting bracket, and the length of the connecting bracket is adjusted according to the different distances between the vehicle body frame 200 and the second bracket 3 in different vehicle models.

[0038] As shown Figure 4 in FIG. Figure 4 , the third bracket 4 is installed on the lower edge of the fender body 1, and the contour of the third bracket 4 matches the contour of the lower edge of the fender body 1. The third bracket 4 is set with a contour matching the contour of the lower edge of the fender body 1, and the part of the third bracket 4 near the wheel arch is connected to the wheel arch, and the part of the third bracket 4 away from the wheel arch is connected to the vehicle body frame 200. Only by setting one third bracket 4 near the wheel arch can the connection between the fender body 1 and the wheel arch be realized and the wheel arch position be supported, reducing the number of brackets and thus reducing the installation process.

[0039] At the position of the third bracket 4 near the wheel arch of the fender body, a first reinforcing cavity 41 and a second reinforcing cavity 42 are provided. The first reinforcing cavity 41 is arranged along the length direction of the third bracket 4, and the second reinforcing cavity 42 is arranged along the inside-outside direction of the vehicle body. A wheel arch mounting position is provided on the cavity surface of the second reinforcing cavity 42. The first reinforcing cavity 41 is arranged along the length direction of the third bracket 4 to strengthen the stiffness at the wheel arch. A second reinforcing cavity 42 is also provided on the third bracket 4 near the wheel arch position. The wheel arch mounting position on the cavity surface of the second reinforcing cavity 42 is specifically a second mounting hole 43, a welding point or an adhesive point. Taking the wheel arch mounting position as the second mounting hole 43 as an example, the second mounting hole 43 is connected to the wheel arch through a fastener. Since the opening of the second mounting hole 43 reduces the strength of this position, the second reinforcing cavity 42 is provided to form a stepped structure at the position where the second mounting hole 43 is provided, compensating for the strength loss caused by the opening of the second mounting hole 43.

[0040] Exemplarily, two wheel arch mounting positions are provided at the position of the third bracket 4 near the wheel arch, and six vehicle body frame mounting positions for connecting to the vehicle body frame 200 are also provided on the third bracket 4. The vehicle body frame mounting positions are also connected to the vehicle body frame 200 through fasteners. Among them, the fastener is preferably a bolt.

[0041] A connecting flange 5 for connecting to the rear bumper is further provided at the rear of the fender body 1. Exemplarily, five third mounting holes 6 are provided on the connecting flange 5 for connecting to the rear bumper through fasteners. The provision of the connecting flange 5 at the rear of the fender body 1 reduces the development of brackets and lowers the cost. Among them, the fastener is preferably a bolt. Using bolt connection is simple and convenient, which can not only improve production efficiency and reduce costs, but also facilitate maintenance.

[0042] In some embodiments, the connection lines of multiple brackets are in a triangular shape, a rhombus shape, a circular shape, a "day" character shape or a "rice" character shape. The multiple brackets are arranged in various shapes to improve the structural stability between the multiple brackets.

[0043] In some embodiments, the fender body 1 is a carbon fiber composite material plate, and the bracket is a carbon fiber composite material bracket, which can achieve lightweight. Specifically, the density of carbon fiber composite materials is generally 1.5-2.0g / cm3. In this embodiment, the material density of the carbon fiber composite material plate is 1.6g / cm3, which is about 1 / 5 of the traditional steel material, and can reduce weight by more than 50% under the same strength conditions. Carbon fiber composite materials also have good impact resistance, can better absorb energy when hit, and improve safety performance.

[0044] Compared with fenders and brackets made of stamped parts, the fender body 1 and bracket made of carbon fiber composite panels avoid the problem of cracking and wrinkling of stamped parts during the part development stage, resulting in low material utilization, and avoid the problem of stamped parts needing spot welding for connection, strict requirements on the width of riveted edges and welded edges, and high costs. Carbon fiber composite materials are used for hot pressing process molding, and only single-sided molds need to be developed for molding, and the mold cost is greatly reduced compared with traditional stamped parts; part modeling has no process restrictions such as drawing depth, and can achieve complex and exaggerated appearance design, solving the problem of optimization restrictions caused by modeling restrictions.

[0045] A second embodiment of the present utility model provides a vehicle, comprising the above-mentioned rear fender structure.
