Description

Technical Field

[0001] This utility model relates to the field of pneumatic comfort system technology, and in particular to an ultra-thin, low-air-resistance massage support valve body. Background Technology

[0002] Currently, automotive seat comfort systems—pneumatic products—control the air circuits through solenoid valves. The air circuit module uses solenoid valves to control the inflation and deflation of each air circuit to achieve the operation of the air circuit module. The solenoid valve is composed of multiple electromagnets and air circuits spliced ​​and welded in series on a PCBA. The internal components and electromagnets are protected by upper and lower shells. This makes the valve body thick, with high air resistance and heavy weight, resulting in low gas utilization and occupying more space.

[0003] To address the shortcomings of existing technologies, it is necessary to design an ultra-thin, low-air-resistance massage support valve body. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an ultra-thin, low-air-resistance massage support valve body.

[0005] An ultra-thin, low-air-resistance massage support valve body includes an outer shell, a PCB board fixed inside the outer shell, and a plurality of massage solenoid valves fixed on the PCB board. The massage solenoid valve includes a solenoid valve housing, on which a first connection port, a second connection port, a third connection port, and a fourth connection port are provided. A first air passage and a second air passage are also provided inside the solenoid valve housing, which are perpendicularly intersecting and connected. The first connection port and the second connection port are connected through the first air passage, and the third connection port and the fourth connection port are connected through the second air passage. Both the first air passage and the second air passage are straight channels.

[0006] Furthermore, the third connection port is a concave groove, and the fourth connection port is a convex block. The convex block has a notch, and a sealing ring is installed in the notch. The fourth connection port of an adjacent massage solenoid valve is inserted into the concave groove of the third connection port of another massage solenoid valve through the convex block, so that the second air passages in several massage solenoid valves are connected to form an inflation channel. An inflation device is installed at one end of the inflation channel, and a sealing ball is set at the other end.

[0007] Furthermore, the massage solenoid valve also includes an electromagnet mounted on the solenoid valve housing.

[0008] Furthermore, a spool is provided near the first connection port on the solenoid valve housing, and the first air passage is a venting channel. One end of the venting channel is provided with an air inlet, and the other end is provided with a plug that can be inserted into the spool.

[0009] Furthermore, a power socket is also provided on the PCB board.

[0010] Beneficial effects: This utility model sets both the first and second air passages as straight channels and splices them in a straight-through manner, which effectively reduces air resistance and improves the utilization rate of gas. It minimizes flow loss in the application scenario, and has a small size, reducing space occupation. It is also lightweight, making the combined massage support valve body thinner.
