[0019] Beneficial Effects

[0020] 1. The present application claims protection for a multifunctional protective bracket, which is mainly used for the lower part of the vehicle body, and aims to solve the problem that the controller assembly is easily damaged by unexpected situations such as squeezing by protrusions on the ground, hitting by flying stones, etc. due to the integral protective plate. Therefore, a protective frame in the shape of an armrest is provided, and the protective frame and the vehicle frame are enclosed to form a space separating the controller assembly from the ground, thereby protecting the controller assembly. The protective frame is integrally formed and has a simple structure. Therefore, it is not only simple to produce, but also can well guarantee the protective strength when protecting. Moreover, the protective frame directly shares the bolt holes with the main reduction assembly. In this way, the integrated installation during installation can reduce the installation of parts, so the problems of fragmentation and complexity can be avoided during disassembly and assembly.

[0021] 2. Further, the protection frame includes a connecting frame in the shape of an armrest and a protective plate in the shape of a concave arc. In fact, in the present application, the shape and size of the protection frame can be adaptively adjusted according to the positions of the frame, the controller assembly and the main reduction assembly, so as to be more suitable for different vehicles; but in the present application, since the connecting frame is in the shape of an armrest and is disposed on both sides of the frame, firstly, a mounting point can be provided for the protection frame, and secondly, during installation, it is obvious that by pre-tightening the fastening bolts first and then tightening the connecting frames on both sides in sequence, it can be ensured that during installation, the position of the protection frame will not be moved due to the large torque of the fastening bolts;

[0022] In addition, the arc-shaped setting of the protective plate can well envelope the controller assembly, thereby achieving better protection.

[0023] 3. Furthermore, the connecting frame is inverted, and the bottom extends away from the frame. At this time, not only can the key parts of the controller assembly be protected, but the inclined extension layout can also reduce material costs as much as possible, achieving light weight, less material, but effective protection effect.

[0024] 4. Furthermore, drainage holes are provided on the protective frame, and the drainage holes are arranged at the lowest point of the concave arc surface of the protective plate. In this way, silt and sewage accumulation on the protective frame can be avoided in rainy days or harsh environments. The arc has a natural guiding advantage, and water and silt can flow along the arc surface of the protective plate to the drainage holes for drainage.

[0025] 5. Obviously, the protective frame is a metal plate formed by integral stamping and has a large area. During the protection process, deformation and other problems may occur. Taking this into consideration, the present application further arranges flanges and reinforcing ribs, all of which can enhance the strength of the protective frame, and the arc transition can reduce the problem of breakage.
