Description

Technical Field

[0001] The utility model relates to the technical field of automobile products, in particular to a winding electromagnetic valve assembly with a valve body frame and a yoke iron bracket fixing device. Background Art

[0002] In order to improve the comfort of car seats, some car seats will be equipped with pneumatic comfort systems. The pneumatic lumbar support system achieves lumbar support and adjustment of lumbar support comfort by inflating and deflating air bags. The electromagnetic air valve must simultaneously meet the functions of inflation, pressure maintenance and deflation. Previous products usually require two electromagnetic air valves to meet the inflation, pressure maintenance and deflation functions of an air bag, which not only increases the complexity and volume of the structure, but also increases the cost of the product.

[0003] With the rapid development of the automobile industry and the expansion of market demand, new energy vehicles are becoming more and more popular, and the requirements for corresponding parts structure in terms of noise and space design are becoming higher and higher.

[0004] At present, the pneumatic lumbar support in the industry mainly uses a controller-mounted valve to control the inflation and deflation switch of the system. The structure, size, and height of the valve will affect the arrangement and placement of the control system inside the seat. The firmness of the valve yoke iron bracket will affect the functional stability of the parts, and abnormal noise will also be generated during shaking.

[0005] A solenoid valve is a device that works based on the principle of electromagnetic induction. It is mainly used to control the flow of fluids (such as gas or liquid). It consists of two parts: an electromagnet and a valve body. The electromagnet part includes a coil, a valve core and a valve body. Its working principle can be summarized as follows: When powered on: the current passes through the electromagnetic coil to generate a magnetic field, which acts on the valve core, attracting or pushing the valve core open, causing the valve core to move, thereby changing the inlet and outlet states of the valve body to achieve fluid on-off control or flow regulation. When powered off: the electromagnetic force disappears, the valve core resets under the action of the spring force, closes the valve, and maintains the stability of the fluid flow.

[0006] Solenoid valves play an important role in automated control systems. They can automatically control based on signals from sensors, controllers, etc., to achieve functions such as automatic switching of fluids and flow rate control, thereby improving production efficiency and equipment stability.

[0007] The existing patent publication number is: CN 109987008 A, which discloses a pneumatically adjustable lumbar support solenoid valve for automobile seats, including a valve body made of plastic material, an inflation valve assembly, an exhaust valve assembly and a silencer. The left and right ends of the valve body are respectively provided with an inflation valve cavity and an exhaust valve cavity, and the middle part is provided with an inflation cavity, an exhaust channel and a silencer cavity. The inflation valve assembly and the exhaust valve assembly are respectively arranged in the inflation valve cavity and the exhaust valve cavity. The outer surfaces of the inflation valve cavity and the exhaust valve cavity are both wound with enameled coils. The inflation cavity is arranged on one side close to the inflation valve cavity and is connected with the inflation valve assembly. The silencer cotton is arranged in the silencer cavity, and the exhaust channel is arranged above the silencer cavity and is connected with the air path. The convex point on the rubber exhaust valve core pad collides with the air nozzle, avoiding the collision and contact between metal and metal surfaces, the contact sound is small and the noise is low, the use effect is good, the use experience is good, the parts are less damaged and not easy to be damaged, the use cycle is long and the use cost is low, no frequent maintenance and replacement are required, the use is convenient and simple, and does not affect the lumbar support adjustment and airbag exhaust.

[0008] However, in the prior art, the bracket is engaged on the valve body, but the position is not firm enough, which can easily cause left and right and up and down shaking, produce abnormal noise, and the operator cannot accurately engage the bracket, resulting in shaking. The bracket may fall off, causing rework and increased costs, and low efficiency. After the valve body is powered on, the starting voltage is unstable, resulting in a reduced lifespan, and the left and right sides interfere with the PIN, causing a short circuit failure.
