[0025] The following describes the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0026] See Figures 1 to 10 The present invention provides an integrated device of an air pump and a solenoid valve group 4 for a car, comprising: a motor 1, a balancing block 2, an integrated housing 3, a solenoid valve group 4 and a pressure plate 5. The integrated housing 3 is integrated with a single piston opening 31, a valve connection port 32 and an airway mechanism 7. The solenoid valve group 4 is placed in the valve connection port 32. The pressure plate 5 fixes the solenoid valve group 4. The pressure plate 5 is detachably connected by bolts. At the same time, the motor 1 is connected to the integrated housing 3. The motor 1 can move the piston rod 35 provided in the integrated housing 3. The single piston mechanism can maximize the optimization of the internal structure of the air pump, thereby reducing costs while ensuring efficiency. The solenoid valve group 4 can control the inflation and deflation of the air suspension in the car, thereby improving the stability of the car.

[0027] exist Figures 1 to 10 In an optional embodiment, the motor 1 has an output shaft 11 at the center.

[0028] Furthermore, the motor 1 includes a first housing 12 and a first bearing 15 . There are two first bearings 15 , which are disposed at both ends of the output shaft 11 . The first bearings 15 are used to assist the output shaft 11 in rotating.

[0029] Furthermore, the motor 1 is connected to the integrated housing 3 by screw connection. Therefore, the output shaft 11 can be docked into the integrated housing 3.

[0030] It should be noted that the first bearing 15 is used to provide support for the rotation of the output shaft 11 , and a heat dissipation mechanism may be provided inside the motor 1 to improve the output performance of the motor 1 .

[0031] exist Figures 1 to 10 In an optional embodiment, one end of the balancing weight 2 is connected to the output shaft 11, and the motor 1 drives the balancing weight 2 to rotate. The other end of the balancing weight 2 is provided with a rod connection hole 21. The balancing weight 2 can rotate as the motor 1 rotates under the drive of the output shaft 11.

[0032] Therefore, the rod connecting hole 21 can rotate along the axis of the output shaft 11 as the center of the circle.

[0033] Furthermore, a single piston opening 31 is integrated and opened at the middle end of the integrated housing 3 , and a plurality of valve connection ports 32 are also provided on the peripheral side of the integrated housing 3 .

[0034] At the same time, the balancing weight 2 is disposed in the single piston opening 31. One end of the piston rod 35 is connected to the rod connection hole 21, and the other end of the piston rod 35 is in close contact with the open end of the single piston opening 31. The piston rod 35 is initially positioned coaxially with the single piston opening 31. When the motor 1 drives the balancing weight 2 to rotate, the piston rod 35 oscillates back and forth in the single piston opening 31.

[0035] Therefore, the piston rod 35 can be moved under the drive of the motor 1, thereby completing the operation of the air pump. It should be emphasized that the present invention is a single-piston air pump, and the above design can maximize cost savings while ensuring its normal performance.

[0036] exist Figures 1 to 10 In an optional embodiment, the solenoid valve group 4 includes a first solenoid valve 41 , a second solenoid valve 42 , a third solenoid valve 43 , a fourth solenoid valve 44 , four fifth solenoid valves 45 and an exhaust solenoid valve 46 .

By opening / closing the above four solenoid valves, the airbags of the air suspension can be effectively inflated / exhausted, and the airbags can provide support for the air suspension, thereby ensuring the comfort of the user during use.

[0038] Furthermore, the solenoid valves in the solenoid valve group 4 are respectively arranged in the valve connection port 32. There are airbags on all four sides of the air suspension of the car. When the airbags are to be inflated, the first solenoid valve 41, the second solenoid valve 42, the third solenoid valve 43 and the fourth solenoid valve 44 are opened.

The safety valve 47 is used to protect the system and limit the load of the motor.

[0040] exist Figures 1 to 10 In an optional embodiment, the integrated housing 3 includes an air passage mechanism 7, and each solenoid valve in the solenoid valve group 4 is disposed in the air passage mechanism 7. The air passage mechanism 7 includes an air inlet duct 71 and an air outlet duct 72. One end of the air outlet duct 72 is connected to the exhaust solenoid valve 46, and the other end of the air outlet duct 72 is connected to the exhaust port 61. The air passage ensures the flow of gas, thereby effectively ensuring the operation of the solenoid valve group 4.

[0041] Furthermore, the pressure plate 5 is fixed to the integrated housing 3 by bolts, and the solenoid valve group 4 is fixed to the integrated housing 3 through the pressure plate 5. The pressure plate 5 has a first notch 51 at the solenoid valve installation location in each solenoid valve group 4. The user can easily remove the pressure plate 5 by unscrewing the bolts. Compared with the traditional snap-on pressure plate 5, the pressure plate 5 of the present invention is more convenient for disassembly, assembly and maintenance.

[0042] Furthermore, each valve connection port 32 is provided with a solenoid valve pole shoe 36, and the solenoid valve pole shoe 36 and the armature are mounted on the body of each solenoid valve in the solenoid valve group 4, and the pressure plate 5 abuts against the solenoid valve pole shoe 36. At the same time, a coil can be provided around it.

[0043] Each solenoid valve in the solenoid valve group 4 is equipped with a yoke 34, which is inserted into the first notch 51 and has an interference fit with the pressure plate 5. This design forms a complete magnetic circuit, while the pressure plate 5 can effectively withstand the force of the gas on the solenoid valve body.

[0044] Furthermore, a rear cover 6 is positioned above the yoke 34 and adjacent to the yoke 34. An exhaust port 61 and an air inlet 62 are also provided on the side of the integrated housing 3 adjacent to the motor 1. The rear cover 6 may or may not contain a controller circuit board. In one embodiment of the present invention, an elastic ring is positioned between the rear cover 6 and the yoke 34. In other embodiments, an elastic ring is positioned between the controller circuit board and the yoke 34. The elastic ring compensates for installation tolerances, ensuring a tight fit and further securing the individual solenoid valves in the solenoid valve assembly 4.

[0045] It should be noted that the bearing press-fitting of the motor 1 and the assembly of the balance block 2 are both carried out on the same side of the integrated housing 3 and on the opposite side of the motor 1 installation. No additional process holes and plugs are required. The pressure plate 5 encapsulates the mounting hole and does not require additional process holes and plugs. The structure is simple and the cost is low.

[0046] Furthermore, the second bearing 37 is arranged opposite to the first bearing 15 , and the second bearing 37 is directly press-fitted between the balancing weight 2 and the output shaft 11 .

[0047] The same or similar parts between the various embodiments in this specification can be referred to each other, and each embodiment focuses on the differences from other embodiments.

[0048] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application.
