Technical Field

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

[0002] The automobile vacuum pump is a type of metering diaphragm pump used for power assistance. When it is running, it can continuously pump air into the equipment to make it close to a vacuum state, forming a negative pressure and generating a relatively large suction force, which can provide power assistance.

[0003] The existing automobile vacuum pumps have the following main drawbacks during use: some automobile vacuum pumps do not take into account the bumps during the driving of the car, which will cause the automobile vacuum pump to be bumped by external forces. Long-term bumps will affect the service life of the automobile vacuum pump and it is difficult to meet the use requirements of the automobile vacuum pump. Therefore, a shock-resistant automobile vacuum pump is proposed. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted by the utility model is: a shock-resistant automobile vacuum pump, comprising: a main body module, the main body module comprising a vacuum pump body, protrusions symmetrically fixed on both sides of the vacuum pump body, a fixing frame arranged on one side of the vacuum pump, round rods symmetrically fixed on both sides of the fixing frame, a movable seat movably sleeved on the round rods, a rubber airbag symmetrically fixed at the top and bottom ends of the movable seat and connected to the fixing frame, and a locking piece movably mounted on the movable seat and extending out of the movable seat.

[0006] The movable seat comprises a sleeve movably sleeved on the round rod, a support arranged between the opposite sleeves and fixedly connected to the sleeves on both sides, and a first spring symmetrically arranged at the top and bottom ends of the sleeves.

[0007] The locking member includes a bottom plate arranged on one side of the support, plug posts fixed in an array on the bottom plate and extending through the support, an annular plate fixed on the plug posts, and a second spring connecting the annular plate and the inner wall of the support.

[0021] 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.

[0022] Some embodiments of the present invention are described below in conjunction with the accompanying drawings. Embodiment 1

[0023] Combination Figure 1-4 As shown, this embodiment provides a shock-resistant automobile vacuum pump, including: a main body module 100.

[0024] Among them, the main body module 100 includes a vacuum pump body 110, protrusions 120 symmetrically fixed on both sides of the vacuum pump body 110, a fixing frame 130 arranged on one side of the vacuum pump, a round rod 140 symmetrically fixed on both sides of the fixing frame 130, a movable seat 150 movably sleeved on the round rod 140, a rubber airbag 160 symmetrically fixed at the top and bottom ends of the movable seat 150 and connected to the fixing frame 130, and a locking piece 170 movably installed on the movable seat 150 and extending out of the movable seat 150.

[0025] The fixing frame 130 is U-shaped, and waist-shaped holes are symmetrically opened on one side of the fixing frame 130 to facilitate the fixing frame 130 to be installed on the vehicle by bolts. Round rods 140 are symmetrically fixed on both sides of the fixing frame 130 for installing the movable seat 150.

[0026] The movable seat 150 is used to install the vacuum pump body 110 and perform shock absorption and buffering on the vacuum pump body 110, including a sleeve 152 movably sleeved on the round rod 140, a support 151 arranged between the relative sleeves 152 and fixedly connected to the sleeves 152 on both sides, and a first spring 153 symmetrically arranged at the top and bottom ends of the sleeve 152. The sleeve 152 is movably sleeved on the round rod 140, used to install the support 151, and limit the movement of the support 151 to ensure the stability of the support 151 when it moves up and down. The support 151 is used to install the vacuum pump body 110. The pump body 110 and the support 151 have grooves 1511 on the inner sides, and the protrusion 120 is embedded in the groove 1511, that is, the vacuum pump is fixed on the support 151. The first spring 153 is sleeved on the round rod 140, and one end is fixed to the sleeve 152, and the other end is fixed to the fixing frame 130. When the vacuum pump body 110 drives the support 151 to vibrate upward, the spring above the sleeve 152 can buffer and absorb the vibration. When the vacuum pump body 110 drives the support 151 to vibrate downward, the spring below the sleeve 152 can buffer and absorb the vibration.

[0027] The rubber airbag 160 is arranged at the top and bottom ends of the support 151 and is filled with gas. When the support 151 vibrates, it can drive the gas in the rubber airbag 160 to be compressed, thereby consuming the impact force of the support 151 during vibration, cushioning the support 151, and cooperating with the first spring 153 to further improve the seismic resistance of the vacuum pump body 110.

[0028] The locking member 170 is used to limit and fix the vacuum pump body 110, and includes a bottom plate 171 arranged on one side of the support 151, a plug post 172 fixed in an array on the bottom plate 171 and extending through the support 151, an annular plate 173 fixed on the plug post 172, and a second spring 174 connecting the annular plate 173 and the inner wall of the support 151. Circular holes are opened in an array on the support 151, and the plug post 172 can be movably extended through the circular holes. At the same time, an annular groove is opened on the inner wall of the circular hole. The annular plate 173 is fixed on the plug post 172 and is located in the annular groove. One end of the second spring 174 is fixed to the annular plate 173, and the other end is fixed to the inner wall of the annular groove, so as to ensure that the plug post 172 always extends outward. The bottom plate 171 is used to fix and connect multiple plug posts 172 together to form a whole. A pull ring is fixed on one side of the bottom plate 171 to facilitate the user to pull the bottom plate 171 to move.

[0029] In addition, a slot 121 is opened on the outer surface of the protrusion 120. When the protrusion 120 is engaged in the groove 1511 on the support 151, the bottom plate 171 is loosened, and the end of the plug 172 extends out of the support 151 and is engaged in the slot 121, thereby fixing the protrusion 120 and the support 151 together, that is, fixing the vacuum pump body 110 and the movable seat 150 together.

[0030] The working principle and use process of the utility model are as follows: when in use, the locking piece 170 is pulled outward to embed the protrusions 120 on both sides of the vacuum pump body 110 into the grooves 1511 on the support 151, and the locking piece 170 is released at this time. Under the action of the second spring 174, the plug post 172 is driven to reset and inserted into the slot 121 on the protrusion 120 to limit the protrusion 120, that is, the vacuum pump body 110 and the movable seat 150 are fixedly connected together. The disassembly is similar. Only the locking piece 170 needs to be pulled out to one side to release the limit of the locking piece 170 on the protrusion 120. At this time, the vacuum pump body 110 can be moved out. When the vacuum pump body 110 encounters a bump in the car, the vibration is transmitted to the movable seat 150 and drives the movable seat 150 to vibrate synchronously. At this time, the first spring 153 and the rubber airbag 160 can buffer and absorb the vibration generated by the movable seat 150, thereby protecting the vacuum pump body 110.

[0031] 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 purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
