[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution 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, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] The embodiment of the present application provides a rust-proof rear bumper pedal and a vehicle, which can solve the technical problem in the prior art that the internal bracket frame of the pedal is easily rusted due to inadequate spraying, thus affecting the overall service life.

[0025] Figure 1 : This is a schematic diagram of a rust-proof rear bumper pedal structure provided in an embodiment of the present application, which includes a rear bumper assembly and a pedal assembly. Specifically, the rear bumper assembly includes a rear bumper shell 1 and rear bumper brackets 101 arranged on both sides of the rear bumper shell 1 facing the rear end of the vehicle; the pedal assembly includes a pedal 2 located in a downwardly recessed position in the middle of the rear bumper and a hollow supporting square steel 3 located at the bottom of the pedal 2, and both ends of the supporting square steel 3 are provided with leakage holes 4 for the spraying liquid accumulated on the surface of the supporting square steel 3 to penetrate into the inner wall of the supporting square steel 3 during the spraying process.

[0026] The rear bumper assembly includes a rear bumper shell 1 and a rear bumper bracket 101 arranged in the rear bumper shell 1 and facing the rear end of the vehicle. The rear bumper shell 1 is generally made of polyester and polypropylene materials, is made by injection molding, and is fixedly connected to the rear bumper bracket 101 to form a whole. The rear bumper bracket 101 is mainly used to enhance the overall stability of the rear bumper assembly.

[0027] Furthermore, a collapsed area that collapses downward is provided in the middle position of the rear bumper shell 1, and the overall shape is an inverted "F" with the collapsed area as the central axis. The rear bumper shell 1 is divided into a symmetrically arranged left shell and a right shell. A rear bumper bracket 101 is respectively installed on the inner surface of the left shell and the right shell. The rear bumper bracket 101 can be set as a horizontal steel beam, and a longitudinal steel beam can be further vertically set at the center point of the horizontal steel beam. The setting form does not affect the installation of the rear bumper assembly, and there is no specific restriction in the present application.

[0028] The pedal assembly is located in the collapsed area of ​​the rear bumper assembly. The pedal assembly includes a pedal 2 and a supporting square steel 3 located at the bottom of the pedal 2. The pedal 2 is arranged horizontally along the vehicle body. It is generally made of aluminum alloy. The supporting square steel 3 at the bottom is mainly used to support the pedal 2 to prevent it from sinking or breaking when stepped on, so that the pedal 2 has sufficient stepping strength. The square steel pipe is a cold-bent steel pipe with higher hardness than ordinary pipes, especially in terms of load-bearing performance. In production, the use of square pipes as materials can greatly improve its bearing capacity and service life. In order to reduce the vehicle body automatic, the supporting square steel 3 is hollow. Although the supporting square steel 3 is arranged at the bottom of the pedal 2 and is wrapped by the rear bumper shell 1, it will still be exposed to air and water, and there will still be a risk of rust and decay. Therefore, when welding the supporting square steel 3, After the connection is completed, it is often necessary to spray anti-corrosion and anti-rust paint on its surface, but the viscosity of anti-corrosion and anti-rust paint is generally high, and it will accumulate on the surface of the supporting square steel 3 during the spraying process. At the same time, during the spraying process, the hollow inner wall of the supporting square steel 3 cannot be sprayed in place, which makes the supporting square steel 3 have the risk of rusting and rotting from the inside. Therefore, in the present application, leakage holes 4 are provided at both ends of the supporting square steel 3, and the leakage holes 4 are square openings with a width of 5MM and a length of 10MM. When spraying, the supporting square steel 3 is hung obliquely for spraying, and the anti-corrosion and anti-rust paint can flow into the interior of the supporting square steel 3 through the leakage holes 4. While achieving comprehensive coverage of the supporting square steel 3 with anti-corrosion and anti-rust paint inside and outside, it can also prevent the accumulation of anti-corrosion and anti-rust paint, thereby improving the aesthetics of the spraying process and the corrosion resistance of the supporting square steel 3.

[0029] Furthermore, rear fog lamp brackets 102 are provided at both ends of the rear bumper shell 1, and the rear fog lamp brackets 102 correspond to the installation position of the rear fog lamp of the vehicle body. The size and shape of the rear fog lamp brackets 102 depend on the rear fog lamp models of different vehicle models. There is no specific restriction in the present application. The rear fog lamp brackets 102 are commonly used components in the technical field and will not be elaborated on here.

[0030] The rear bumper assembly is installed at the rear of the vehicle. Its appearance is consistent with the shape of the rear of the vehicle and completely wraps the rear of the vehicle. Therefore, the two ends of the rear bumper shell 1 are bent and extended toward the front of the vehicle to form a curved portion 103 that wraps the two sides of the rear of the vehicle. It should be noted that the rear bumper shell 1 body and the curved portion 103 can be formed in one piece or in a split manner. When the rear bumper shell 1 body and the curved portion 103 are two separate parts, the two can be connected by welding. The rear bumper bracket 101 is installed on the curved portion 103 and the ends of the rear bumper brackets 101 that are far away from each other are connected to the curved portion 103, and the ends of the two rear bumper brackets 101 that are close to each other are respectively connected to the two ends of the supporting square steel 3.

[0031] Furthermore, the rear bumper bracket 101 and the curved portion 103 can be directly fixedly connected, or a curved support plate can be provided at one end of the two rear bumper brackets 101 that is away from each other, that is, the connecting end of the rear bumper bracket 101 and the curved portion 103, and the curved surface of the support plate fits with the curved surface of the curved portion 103 to increase the contact area between the two, so that the rear bumper bracket 101 can better fit with the rear bumper shell 1, and at the same time can also support the curved portion 103, thereby enhancing the overall firmness of the rear bumper assembly.

[0032] Furthermore, in order to further enhance the stability of the rear bumper bracket 101, in the present application, the rear bumper bracket 101 is fixedly connected to the supporting square steel 3 as a whole. Specifically, the two ends of the supporting square steel 3 are welded to the ends of the two rear bumper brackets 101 that are close to each other. The supporting square steel 3 and the two rear bumper brackets 101 form the internal lateral support system of the rear bumper pedal in the present application.

[0033] Furthermore, the lateral support system can not only provide support to the rear bumper shell 1 from the inside, but also be used to be connected with the frame longitudinal beam screws to firmly connect the rear bumper pedal in the present application to the rear of the vehicle.

[0034] Specifically, a connecting plate 5 for connecting the rear bumper assembly to the vehicle body is provided at the connection between the supporting square steel 3 and the rear bumper bracket 101. The connecting plate 5 is made of steel and is mainly connected to the vehicle body by bolts. Therefore, a plurality of connecting holes are provided on the connecting plate 5 for the connecting bolts to pass through. The setting form and setting orientation can be adapted to the rear shape of different vehicle models, and there is no specific restriction in the present application.

[0035] For further details, see Figure 2The supporting square steel 3 includes two hollow square tubes 301 with a leakage hole 4 at one end, and the two square tubes 301 are welded together at one end without the leakage hole 4. The arc welding process is used between the two square tubes 301 to improve the structural strength and bending resistance of the weld, ensure the stability of the weld quality, reduce loss, ensure the overall quality of the supporting square steel 3, and achieve seamless welding, making the surface of the supporting square steel 3 more beautiful. In addition, the two square tubes 301 are both provided with a leakage hole 4 at one end, and the two square tubes 301 are welded at one end without the leakage hole 4 to maintain normal leakage at both ends of the supporting square steel 3.

[0036] Furthermore, the pedal 2 is arranged above the welding point of the two groups of square tubes 301. In order to maintain the uniform force of the supporting square steel 3 as a whole and the overall aesthetics of the vehicle body, the pedal 2 is arranged above the welding point of the two groups of square tubes 301, and the center point of the pedal 2 and the weld of the two groups of square tubes 301 are located on the same longitudinal axis.

[0037] During actual use of the vehicle, a tow hook may be installed at the rear bumper, and the pulling force of the tow hook will be dispersed to the supporting square steel 3 and the bumper bracket. Simply relying on the connecting plate 5 may not be able to meet the large-tonnage pulling force. Therefore, in the present application, the pedal assembly also includes a pedal reinforcement plate 201 that is arranged along the height direction of the vehicle body and vertically on the side of the pedal 2 facing the direction of the vehicle body.

[0038] Specifically, the pedal reinforcement plate 201 is also made of steel material, and the pedal reinforcement plate 201 is arranged on the side of the pedal 2 close to the rear of the vehicle and is directly connected to the vehicle body during installation, which helps to improve the strength of the pedal 2 along the height direction of the vehicle and helps to disperse the force of the pedal 2 and the rear bumper assembly. Furthermore, a connecting member 202 is provided on the pedal reinforcement plate 201. The pedal reinforcement plate 201 is generally connected to the rear of the vehicle by bolts. Therefore, in one embodiment of the present application, the connecting member 202 is a plurality of screw holes for the bolts to pass through.

[0039] The present application also provides a vehicle, which includes the above-mentioned rust-proof rear bumper pedal assembly.

[0040] The rust-proof rear bumper pedal assembly in the present application can fully cover the inner and outer surfaces of the supporting square steel 3 serving as the supporting frame with anti-corrosion materials to prevent it from rusting and rotting from the inside, thereby effectively improving the overall service life of the rear bumper pedal assembly. During the spraying process, excess anti-corrosion and anti-rust paint can penetrate into the interior of the supporting square steel 3 through the leakage hole 4, thereby effectively preventing paint accumulation and improving the aesthetics and convenience of the sprayed finished product.
