[0002] The brake plate is a key component of the brake plate assembly. It is a supporting component that fixes the brake shoe assembly and the brake drum assembly in the automobile brake and is the core of the vehicle brake.

[0003] After searching, the existing patent (publication number: CN218855699U) discloses a brake base plate for automobiles, which belongs to the field of components of vehicle brake devices, including a brake assembly fixing device arranged on the brake base plate. The key point of this technology is that the cross-section of the brake assembly fixing device is a closed frame-like structure, and the brake assembly fixing device is sleeved on the brake base plate, and the two are fixed as a whole through welding points. After the above-mentioned improvement of the prior art, the present utility model designs the brake assembly fixing device as an integrated frame structure, so that the brake assembly fixing device is easy to machine and install, and no longer requires expensive special machining equipment. Therefore, under the premise of ensuring safety performance, it has the advantages of simple structure, easy machining, high strength, high precision, suitable for assembly line production, and low production cost. In the process of realizing the present utility model, the inventor found that the prior art has the following problems:

[0004] The existing brake bottom plate is usually made of a single piece of solid steel, which makes the workpiece heavy. When the bottom plate is seriously worn, the entire bottom plate can only be replaced. At the same time, it does not have a heat dissipation structure, which can easily cause the bottom plate temperature to be too high during braking, affecting the support strength;

[0005] Therefore, in view of the above problems, a drum brake base plate structure for a van is proposed. Utility Model Content

[0006] In order to overcome the above defects of the prior art, the utility model provides a drum brake base plate structure for a van to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a van drum brake base plate structure, including a base plate, a connecting frame is arranged on the top of the base plate, the outer wall of the connecting frame is connected to an outer ring, the base plate is embedded in the outer ring, and a top plate is arranged at the end of the connecting frame away from the base plate, and the top plate is also embedded in the outer ring. The base plate corresponds to the top plate, and the edge of the connecting frame is arranged with hollows, and the outer walls on both sides of the connecting frame are connected to heat conducting plates, and the outer walls of the base plate and the top plate are penetrated by air holes, and the air holes are connected to the hollows.

[0008] Preferably, the base plate, the connecting frame and the top plate are all provided with center holes at their centers, and a plurality of groups of the center holes are located on the same axis.

[0009] Preferably, flange holes are arranged on the edge of the center hole, limiting grooves are arranged on the outer walls on both sides of the connecting frame, and a No. 1 magnetic sheet is arranged on the inner walls of the two groups of limiting grooves.

[0010] Preferably, a first limiting block is arranged on one side of the base plate close to the connecting frame, and the first limiting block is embedded in the inner wall of the limiting groove on one side.

[0011] Preferably, a second limiting block is arranged on a side of the top plate close to the connecting frame, and the second limiting block is embedded in the limiting groove on a side away from the base plate.

[0012] Preferably, a No. 2 magnetic sheet is disposed at the end of each of the No. 1 limiting block and the No. 2 limiting block, and the No. 2 magnetic sheet is adsorbed onto the No. 1 magnetic sheet.

[0013] Preferably, the outer wall on the side opposite to the top plate is provided with reinforcing ribs, and the outer wall of the outer ring is sleeved with a heat dissipation copper ring.

[0014] Preferably, a camshaft mounting hole is provided on one side of the plurality of groups of center holes, and a support pin hole is provided on a side of the center hole away from the camshaft mounting hole.

[0015] Technical effects and advantages of the utility model:

[0016] 1. Compared with the prior art, the hollow structure of the drum brake base plate of a van can reduce the overall weight of the brake base plate while enhancing the heat dissipation performance of the brake base plate. When the temperature of the base plate and the top plate rises during braking operation, the heat can be transferred to the hollow part of the connecting frame through the heat conductive sheet to facilitate heat dissipation. At the same time, the split design of the base plate and the top plate allows for separate disassembly and replacement when one set of surfaces is worn and damaged, thereby avoiding replacement of the entire brake base plate.
