Description

Technical Field

[0001] The utility model relates to the technical field of bracket structures, in particular to a bracket structure for an automobile pump body. Background Art

[0002] Automobile pump body refers to the equipment installed on the automobile to provide liquid or gas pressure. It is a key component of the automobile cooling system, lubrication system, fuel supply system and other hydraulic or pneumatic systems. The factors that need to be considered in the design and manufacture of automobile pump bodies include but are not limited to the working environment, durability, efficiency, volume and weight. Correct installation and maintenance of automobile pump bodies are crucial to ensure the normal operation of the vehicle and extend the life of the vehicle. In the prior art, automobile pump body brackets are usually used to firmly install the pump body on the vehicle.

[0003] Although the existing automobile pump body bracket is widely used, it still has some defects. Since the car will inevitably encounter bumps during driving, the pump body and the bracket will also shake with the bumps of the vehicle. The long-term shaking of the pump body and the bracket can easily cause damage to the pump body. In addition, the existing pump body installation method is usually welding, which is inconvenient when the pump body needs to be replaced. Therefore, an automobile pump body bracket structure is proposed to address the above problems. Utility Model Content

[0009] Preferably, there are multiple buffer devices, which are distributed in an array on the top of the mounting base plate, and the inner side of the hydraulic cylinder fits tightly with the outer side of the piston.

[0010] Preferably, the sealing ring is fixedly connected to the inner side of the top end of the hydraulic cylinder, the inner side of the sealing ring is tightly fitted with the outer side of the buffer rod, and the first buffer ring and the second buffer ring are the same in shape and size.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the buffer device, hydraulic cylinder, piston, buffer rod, sealing ring, first buffer ring, second buffer ring and circular plate are provided to buffer the pump body, reduce damage to the pump body and increase the service life of the pump body. First, the device is installed on the car, and the installation base plate is installed on the car through the installation hole using a tool. During the operation of the car, as the vehicle bumps, the circular plate is forced to drive the buffer rod down. At this time, the piston follows the buffer rod to drop, and the hydraulic oil in the hydraulic cylinder is compressed. When the road condition is normal, the hydraulic oil slowly recovers and drives the buffer rod to rise, reducing the shaking of the pump body. The first buffer ring and the second buffer ring can buffer the hydraulic cylinder to prevent the hydraulic cylinder from being damaged due to the buffer rod touching the bottom due to excessive bumps. The sealing ring can ensure the sealing of the hydraulic cylinder and prevent foreign dust and other impurities from adhering to the outside of the buffer rod and being brought into the inside of the hydraulic cylinder.

[0013] 2. In the utility model, the installation and disassembly of the pump body is more convenient by providing the first fixing plate, the first circular hole, the first bracket, the second fixing plate, the second circular hole, the second bracket, the bolts and the nuts. When the pump body needs to be installed, the pump body is placed inside the first bracket, and then the second bracket is placed above the first bracket, and the first fixing plate and the second fixing plate are aligned, and then the bolts are inserted into the insides of the first circular hole and the second circular hole, and the nuts are tightened on the outsides of the bolts, and the installation of the pump body is completed. When the pump body needs to be replaced, the nuts are unscrewed and the bolts are unscrewed from the insides of the first circular hole and the second circular hole, and the second fixing plate and the second bracket are removed, and the pump body can be replaced.
