Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pumps, in particular to a bump-resistant automobile vacuum pump. Background Art

[0002] The vacuum pump, also known as the power-assisted pump, is a power-assisted device for the brake system and steering system. The vacuum pump is used to generate vacuum. Ordinary cars have hydraulic power-assisted brakes, while trucks or buses usually have pneumatic power-assisted brakes. The function of the vacuum pump is to generate negative pressure, thereby increasing the braking force. The vacuum pump of a car generator is generally an oil pump, that is, the vacuum pump core rotates with the shaft of the generator. By continuously sucking and pumping oil, the vacuum pump generates negative pressure inside the passenger, that is, vacuum.

[0003] Existing automobile vacuum pumps are generally fixedly installed on the vehicle body. The bumps during long-term use can easily cause the vacuum pump to be damaged by vibration, thereby increasing the maintenance frequency and the cost of using the vehicle. Therefore, we propose a bump-resistant automobile vacuum pump. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0020] A bump-resistant automobile vacuum pump provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0021] Combination Figure 1-2As shown, the utility model provides a bump-resistant automobile vacuum pump, comprising: a body assembly 100 and a shock-absorbing assembly 200; wherein the body assembly 100 comprises a pump body 110, a mounting plate 120 arranged in the middle of the pump body 110 and an air pipe 130 connected to the pump body 110.

[0022] The shock absorbing assembly 200 is arranged on the pump body 110, and the shock absorbing assembly 200 includes a mounting frame 210 located outside the mounting plate 120 for fixing, a torsion spring shaft 1 220 mounted on the mounting frame 210, a movable pressure plate 230 connected to the torsion spring shaft 1 220, a torsion spring shaft 2 240 fixed to the bottom of the movable pressure plate 230, a shock absorber 250 connected to the torsion spring shaft 240, a spring 260 embedded in the mounting frame 210, a block 270 connected to the outer end of the spring 260, and a spring 260 fixed to the block 270 for supporting the mounting plate 1 The support plate 280 of 20 and the fastening bolt 290 connected to the support plate 280 and the bottom of the shock absorber 250, through the shock absorbing assembly 200, can use the spring 260 and the support plate 280 to support the pump body 110 under the mounting plate 120, and then after the movable pressure plate 230 is loosened, the movable pressure plate 230 will be pressed against the upper part of the mounting plate 120, and at the same time, the shock absorber 250 will be pressed against the mounting plate 120 and enter the placement groove 281, and finally the fastening bolt 290 is screwed in from the bottom of the support plate 280 to fix the shock absorber 250. Such installation of the vacuum pump can greatly reduce the transmission of vibration and reduce the vibration damage to the vacuum pump.

[0023] Furthermore, the support plates 280 are provided in four groups symmetrical to the mounting frame 210, and the support plates 280 are made of hard rubber plates. The groups of support plates 280 have a better supporting and fixing effect on the pump body 110, and the hard rubber plate structure has a certain strength and a good shock absorbing effect.

[0024] On the other hand, the movable pressure plate 230 is a folded plate structure, which can cooperate with the torsion spring shaft 1 220 to have a pressing effect on the vacuum pump, and at the same time play a certain buffering role when it is vibrated.

[0025] It should be noted that a protective pad 231 is provided on the inner side of the movable pressure plate 230, which can play a cushioning role after contacting the pump body 110 and the mounting plate 120, and also play a buffering and shock absorbing role.

[0026] Furthermore, a placement groove 281 for placing the shock absorber 250 is provided on the support plate 280 . The placement groove 281 facilitates the alignment and insertion of the shock absorber 250 , thereby facilitating the subsequent connection operation of the fastening bolt 290 .

[0027] On the other hand, a protective pad 251 is fixed to the inner side of the shock absorber 250 , which also plays a protective role for the mounting plate 120 .

[0028] The working principle and use process of the utility model are as follows: first, the vacuum pump is placed on the inner side of the mounting frame 210, and the pump body 110 is supported and fixed under the mounting plate 120 by using the spring 260 and the support plate 280. Then, after the movable pressure plate 230 is loosened, the movable pressure plate 230 will be pressed against the upper part of the mounting plate 120, and at the same time, the shock absorber 250 is pressed against the mounting plate 120 and enters the placement groove 281. Finally, the fastening bolt 290 is screwed in from the bottom of the support plate 280 to fix the shock absorber 250. The subsequent vibration generated by the vehicle body will be greatly reduced to prevent the mounting plate 120 from being hard-vibrated and damaged along with the vehicle body.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
