Description

Technical Field

[0001] This utility model relates to an automotive device, specifically to an air supply device for integrating airflow. Background Technology

[0002] Automotive air suspension is a new type of vehicle suspension system that uses air springs to replace traditional steel springs and shock absorbers. This system precisely controls the vehicle's height, stiffness, and stability by adjusting the air pressure inside the air springs. Currently, the adjustment and control of air suspension mainly adopts an integrated air system, which includes pneumatic valve blocks, motors, and circuit boards, and is installed inside the vehicle to control the direction of air flow.

[0003] In the existing technology, the pneumatic valve block and the circuit board are connected in a frame, with part of the solenoid valve set in the pneumatic valve block and part set in the circuit board frame, which makes assembly difficult.

[0004] Therefore, there is room for improvement in existing automotive air supply devices. Utility Model Content

The multiple solenoid valves are disposed in the multiple receiving grooves, and the coils of the solenoid valves are disposed in the large-diameter circular holes. The multiple solenoid valves are electrically connected to the electronic controller.

[0008] The vehicle air supply device according to the preferred embodiment of this application includes an electronic controller comprising an upper housing, a lower housing, and a circuit board. The circuit board is disposed between the upper housing and the lower housing. The upper housing has multiple through holes, and the electrical pins of the multiple solenoid valves pass through the through holes and are electrically connected to the circuit board.

[0009] The preferred embodiment of the vehicle air supply device of this application further includes an electronic connection part disposed on the upper housing and electrically connected to the circuit board.

[0010] The preferred embodiment of the vehicle air supply device described in this application further includes multiple pneumatic connectors, air inlets and exhaust ports, which are disposed on the pneumatic valve block.

[0011] The preferred embodiment of the vehicle air supply device of this application further includes a dryer, which is disposed on the pneumatic valve block.

[0012] The design concept of this application is to provide a method in which the solenoid valve is set in the pneumatic valve block, so that the plane of the pneumatic valve block and the plane of the electronic controller are connected, without the problem of difficult connection between the frame and the plane, thus fundamentally eliminating the problem of difficult assembly.

[0013] Due to the adoption of the above technical solutions, this utility model has the following advantages and effects:

[0014] First, this application places the solenoid valve in the convex hole of the pneumatic valve block, so that the connection between the pneumatic valve block and the electronic controller is a surface-to-surface connection, which simplifies the assembly process and saves time.

[0022] For ease of understanding, the preferred embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Please refer to Figure 1This application presents a schematic diagram of the air supply device. The air supply device adopts an integrated component approach, combining a pneumatic valve block, motor, air compressor, dryer, multiple solenoid valves, and electronic controller into a single air supply unit. The core of this air supply unit is the pneumatic valve block, on which all other components are arranged. The pneumatic valve block connects to multiple solenoid valves, and the armature housings of the multiple solenoid valves are riveted to the pneumatic valve block. This provides a compact air supply unit for supplying air to the air spring system of a motor vehicle. Figure 2 The solenoid valve is installed in the convex hole of the pneumatic valve block, so that the connection between the pneumatic valve block and the electronic controller is a surface-to-surface connection, which simplifies the assembly process.

[0024] Please refer to Figure 1 and Figure 2 The air supply device described in this application includes a pneumatic valve block 4, a motor 5, an air compressor 6, multiple solenoid valves 7, and an electronic controller 3. The motor 5 is disposed on one side of the pneumatic valve block 4, and the electronic controller 3 is disposed on the other side of the pneumatic valve block 4. Figure 2 As shown, the motor 5 and the electronic controller 3 are connected to the corresponding two surfaces of the pneumatic valve block 4; the air compressor 6 is disposed in the middle groove of the pneumatic valve block 4, and the air compressor 6 is driven by the motor 5 mounted on one side of the pneumatic valve block 4; the pneumatic valve block 4 has multiple receiving grooves 41 with small-diameter circular holes and large-diameter circular holes forming a convex shape on the side facing the electronic controller 3, and multiple solenoid valves 7 are disposed in the multiple receiving grooves 41. The coil 71 of the solenoid valve 7 is disposed in the large-diameter circular hole, and one end of the armature of the solenoid valve 7 is disposed in the small-diameter circular hole, and the other end is disposed in the large-diameter circular hole. The armature moves under the influence of the magnetic force of the coil 71. During assembly, the outer shell accommodating the armature and the end face of the small-diameter circular hole are riveted together to achieve the functions of fastening and sealing. The coil 71 is sleeved and connected to the outer shell of the armature in the large-diameter circular hole; the multiple solenoid valves 7 are electrically connected to the electronic controller 3.

The electronic controller 3 includes an upper shell 31, a lower shell 32, and a circuit board (not shown). The circuit board is disposed between the upper shell 31 and the lower shell 32 and is not visible in the illustration. The upper shell 31 has multiple through holes 311, and the electrical pins of the multiple solenoid valves 7 pass through the through holes 311 and are electrically connected to the circuit board. The multiple solenoid valves 7 receive instructions from the vehicle computer via the circuit board to open or close. Figure 3 and Figure 4 As shown, the connection between the pneumatic valve block 4 and the electronic controller 3 is a surface-to-surface connection, which simplifies the assembly process and saves time.

The pneumatic valve block 4 includes multiple channels (not shown), which function as pneumatic pipes connecting the air compressor 6, dryer 1, solenoid valve 7, multiple pneumatic connectors 2, air inlets 9, and exhaust ports 10. These pneumatic connectors 2, air inlets 9, and exhaust ports 10 are used to connect to other components of the air spring system, such as accumulators. The air inlets 9 and exhaust ports 10 are equipped with valves that move in opposite directions, coordinating with the movement of the air compressor 6 to perform air intake and exhaust operations.
