Description

Technical Field

[0001] The invention relates to the technical field of new energy vehicles, and in particular to an electronic vacuum pump for new energy vehicles. Background Art

[0002] With the popularization of new energy vehicles, the braking systems of new energy vehicles are also gradually improving. New energy electric vehicles are driven by motors and the traditional engines are eliminated, so the vacuum source is lost, that is, it is impossible to provide vacuum assistance for the car's brake master cylinder. The electric vehicle vacuum booster pump can solve this problem. Electric vehicles use vacuum booster pumps to provide power for the on-board power supply, and the motor on the pump body is driven to move the piston to generate vacuum, so that the driver can easily step on the brakes, thereby effectively improving the braking performance of the entire vehicle.

[0003] Based on the above, the inventors have found that the existing electronic vacuum pump for new energy vehicles mainly has the following deficiencies. For example, the electronic vacuum pump in the new energy vehicle provides power to the vehicle brake system through an air pipe. When the vehicle is driving, the air pipe is easily damaged at the position where it is connected to the electronic vacuum pump due to the shaking of the vehicle, causing the electronic vacuum pump to leak air, resulting in the inability to provide timely assistance to the brake system. In severe cases, it may cause a traffic accident. Summary of the invention

[0022] Example 1: Please refer to Figure 1-Figure 5 , the specific embodiments of the present invention are as follows: Its structure includes a main body 1, a driving motor 2, and a data connection line 3. The bottom of the main body 1 is connected to the top of the driving motor 2 by bolts, and the data connection line 3 is connected to the side end of the driving motor 2; the main body 1 includes a vacuum accumulator 11, a fixing bolt 12, an inner groove 13, a reverse valve 14, an air intake structure 15, a rotor 16, and blades 17. The bottom of the vacuum accumulator 11 is fixedly connected to two fixing bolts 12, and the fixing bolts 12 are respectively arranged on the left and right sides of the vacuum accumulator 11. The inner groove 13 is located inside the vacuum accumulator 11. The reverse valve 14 is arranged on the rear side end face of the vacuum accumulator 11. The air intake structure 15 is arranged at the front end of the vacuum accumulator 11. The rotor 16 is installed in the middle of the inner groove 13, and the end face of the rotor 16 is provided with eight blades 17. The air intake structure 15 includes a connection structure 151, an air pipe 152, and a locking ring 153. The connection structure 151 is bolted to the front end of the vacuum accumulator tank 11, the air pipe 152 is nested in the end face of the connection structure 151, and the locking ring 153 locks the air pipe 152 to the end face of the connection structure 151. The locking ring 153 includes a buffer tube 1531, a fixing ring 1532, a steel wire 1533, and a friction bump 1534. The fixing ring 1532 is provided at the top of the inner part of the buffer tube 1531, and the fixing ring 1532 is fixedly connected to the end surface of the locking ring 153. There are more than five steel wires 1533, and the steel wires 1533 are fixedly connected to the bottom end surface of the fixing ring 1532. The friction bump 1534 is provided on the inner end surface of the buffer tube 1531. The buffer tube 1531 is made of rubber and has good toughness and elasticity; The inner side of the locking ring 153 is provided with a slope with an angle of 45 degrees; The reverse valve 14 has the function of maintaining pressure.

[0023] The buffer tube 1531 is fixedly connected with a metal fixing ring 1532, and the end face of the buffer tube 1531 is supported by a steel wire 1533, so that the deformation of the air pipe 152 can be reduced when following the shaking of the car, thereby avoiding the air pipe 152 from being damaged by long-term shaking, and improving the stability of the electronic vacuum pump.

[0024] Based on the above embodiment, the specific working principle is as follows: the driving motor 2 is used to provide power for the rotor 16, so that the rotor 16 can drive the blades 17 to rotate at a high speed, so that the interior of the inner groove 13 can form a negative pressure, and then the air pipe 152 is connected through the connecting structure 151 to vacuum the automobile brake system to provide brake assistance, so that when the new energy vehicle brakes, the end face of the locking ring 153 of the air pipe 152 is nested in the connecting structure 151, and then the thread on the inner side of the locking ring 153 is connected to the thread on the end face of the connecting structure 151, and the locking ring 153 is locked. During the tightening process of the tightening ring 153, the inclined surface on the inner side of the locking ring 153 can squeeze the air pipe 152, so that the air pipe 152 can be firmly locked, and then the buffer tube 1531 is fixedly connected by the metal fixing ring 1532, and the end face of the buffer tube 1531 is supported by the steel wire 1533, so that the deformation amplitude of the air pipe 152 can be reduced when following the shaking of the car, thereby avoiding the air pipe 152 from being damaged by long-term shaking, and improving the stability of the electronic vacuum pump.

[0025] Example 2: Please refer to Figure 6-Figure 7 , the specific embodiments of the present invention are as follows: The connecting structure 151 includes a connecting seat 1511, a fixing bolt 1512, a ventilation groove 1513, and a connecting tube body 1514. The connecting seat 1511 is locked on the end face of the vacuum pressure accumulator tank 11 by two fixing bolts 1512. The ventilation groove 1513 is located on the inner end face of the connecting seat 1511. The connecting tube body 1514 is fixedly connected to the front end of the connecting seat 1511. Negative pressure can be generated in the groove 1513 to allow the air pipe 152 to assist the braking system of the automobile, so that the new energy vehicle can be easily controlled to brake.

[0026] The connecting tube body 1514 is in a conical shape, and a thread is disposed on the upper end surface of the connecting tube body 1514 ; when the air pipe 152 is squeezed, it can fully fit against the end surface of the sealing ring 1515 , thereby improving the sealing performance of the air pipe 152 .

[0027] Two sealing rings 1515 are disposed on the end surface of the connecting tube body 1514 .

[0028] The sealing ring 1515 is made of rubber and has a good sealing effect.

[0029] The connecting tube body 1514 is movably matched with the interior of the air pipe 152 .

[0030] Based on the above embodiment, the specific working principle is as follows: the connecting seat 1511 is fixedly installed on the end face of the vacuum pressure storage tank 11 by using the fixing bolt 1512, so that when the rotor 16 drives the blades 17 to work and generate negative pressure, negative pressure can be generated in the ventilation groove 1513 to allow the air pipe 152 to assist the braking system of the vehicle, which can easily control the braking of the new energy vehicle, and then the conical shape of the connecting pipe body 1514 is combined with the inclined slope on the inner side of the locking ring 153 to stabilize the squeezing effect on the air pipe 152. At the same time, the air pipe 152 can fully fit the end face of the sealing ring 1515 when squeezed, thereby improving the sealing of the air pipe 152 and avoiding air leakage at the connection position of the air pipe 152 and the connecting pipe body 1514.
