[0002] The mudguard is an important part of the vehicle and is mainly used for preventing the mud, water, stones and other sundries thrown out by the wheels during driving from splashing onto the vehicle body or other parts. The mudguard is usually fixed on the frame by using the mudguard support.

[0003] The traditional structure of the mudguard is shown in the figure, which usually comprises the existing cast base 11, the existing support round pipe 12 and the existing connecting support 13. Figure 1 The existing cast base 11 is connected with the frame longitudinal beam through bolts, the existing support round pipe 12 is connected with the existing cast base 11 through welding, and the existing connecting support 13 is connected with the existing support round pipe 12 through welding, thereby forming a fixed support and realizing the fixing function of the mudguard.

[0004] However, the existing support round pipe 12 has a long protruding part, one end of which is connected with the frame, and the other end of which is suspended to install the existing connecting support 13, forming a cantilever structure. In addition to the dead weight, the existing support round pipe 12 is frequently vibrated during driving, which often causes the breakage of the existing support round pipe 12, affects the service life and increases the use cost.

[0007] The utility model further comprises a mounting plate three, which is connected and mounted between the two mounting plate twos and located below the support connecting rod.

[0008] At least one mounting hole is formed in the mounting plate one, the mounting plate two and the mounting plate three.

[0009] Along the length direction of the mounting plate two, the extension structure of the outer side surface of the mounting plate one and the mounting plate two is adapted to the structure of the mudguard to-be-installed surface, wherein the outer side surface of the mounting plate one and the mounting plate two is the surface that contacts the mudguard to-be-installed surface during installation.

[0010] The utility model discloses a kind of lightweight mudguard support based on, further provide a battery box frame, the battery box frame side is equipped with above-mentioned one lightweight mudguard support, wherein through mounting plate three and battery box frame side connection installation.

[0011] The utility model discloses a kind of lightweight mudguard support based on, further provide a vehicle, install above-mentioned one battery box frame.

[0012] The working principle and the advantage of the utility model are as follows: the bracket of the present application is installed on the battery box frame through mounting plate three, and then the mudguard is installed through mounting plate one and mounting plate two.

[0013] Limited by traditional vehicle space and traditional battery box frame structure, the remaining space reserved for the installation of the mudguard support is limited, so the existing traditional mudguard support structure is adapted to the existing vehicle and battery box frame structure and the limited remaining space.

[0014] However, with the optimization of vehicle structure and battery box frame structure, it is found that the installation space of the mudguard support is also optimized, and under this condition, the support structure is optimized to adapt to the development of vehicle space and solve the existing support problem. The optimized support structure is not only a structural optimization of a single component, but also a change from the original suspended mode to a stable connection fixed body mode, which completely solves the problem of suspension fracture, adapts to the optimization of existing automobile space, and improves the stability and quality of the support.

[0015] The bracket structure of the present application cancels the base design of conventional mudguard support, shortens the support rod, reduces structural redundancy, and greatly reduces the dead weight. All mounting plates and support connecting rods are fixedly connected, the structure is stable, the strength is higher, and the installation is more accurate. More importantly, mounting plate three is directly connected with the end face of the battery box frame, mounting plate one and two mounting plate two are connected with the mudguard, the entire support installation mudguard is mainly supported by the battery box frame, and the overall stress is balanced. Compared with the cantilever structure of the conventional mudguard support and the frame connection, the installation on the battery box frame can avoid the risk of fracture caused by suspension and vibration, greatly increasing the stability of the mudguard support. The entire mudguard support structure is more simple, occupies smaller volume, saves space, and improves the space utilization rate of the whole vehicle layout. BRIEF DESCRIPTION OF DRAWINGS
