Description

Technical Field

[0001] The utility model relates to the technical field of electronically controlled air suspension, in particular to a water - proof structure for a solenoid valve block. Background Art

[0002] There is a close relationship between an air compressor and a solenoid valve. Both the solenoid valve and the air compressor are indispensable components in an air suspension system. The main function of the air compressor is to provide compressed air for the air suspension system, while the solenoid valve is used to control the flow direction, flow rate, and speed of the compressed air, thereby realizing the lifting and lowering of the air spring in the air suspension system. The solenoid valve controls the flow of fluid through electromagnetic action. Its working principle is based on the energization and de - energization of an electromagnet, and then controls the opening and closing of a piston or valve to achieve the control of the compressed air flow path. This control can precisely adjust parameters such as the output direction and pressure of the air compressor to ensure the stable operation of the system. Therefore, the solenoid valve is very important for ensuring the stable operation of the air compressor and the electronically controlled air suspension system.

[0003] In actual use, currently, since there is no water - proof structure for the solenoid valve block, the possibility of water entering the solenoid valve block is very high. Water entering the solenoid valve block will cause rust inside the solenoid valve block or, due to water freezing, cause the solenoid valve block to fail, and further lead to the inability of the ECAS system (electronically controlled air suspension system) to adjust the vehicle body height. Summary of the Utility Model

[0004] To solve the technical problems in the background art, the utility model proposes a water - proof structure for a solenoid valve block.

[0005] A water - proof structure for a solenoid valve block proposed by the utility model 。

[0006] Preferably, it includes an air compressor assembly and a solenoid valve block. The air compressor outlet on the air compressor assembly is connected to the solenoid valve inlet on the solenoid valve block through a high - pressure pipe. The solenoid valve inlet is higher than the air compressor outlet in the positive Z - axis direction and the vertically upward direction.

[0007] Preferably, the solenoid valve inlet is at the lowest point of the solenoid valve block.

[0008] Preferably, the direction of the high - pressure pipe from the connection end at the solenoid valve inlet to the connection end at the air compressor outlet is in the negative Z - axis direction and the vertically downward direction.

[0009] Preferably, both ends of the high - pressure pipe are respectively connected to the air compressor outlet and the solenoid valve inlet through quick - connect joints.

[0010] In summary, the utility model has the following beneficial effects: By setting the air inlet of the solenoid valve block higher than the air outlet of the air compressor in the positive Z-axis direction and the vertically upward direction, when condensate appears in the solenoid valve block, the condensate will flow out from the air inlet of the solenoid valve block due to gravity, enter the air outlet of the air compressor through the high-pressure pipe, and finally enter the interior of the air compressor assembly. Inside the air compressor assembly, due to the presence of a dryer, there is a certain space for absorbing and storing moisture. Therefore, when moisture enters the interior of the air compressor dryer, no failure will occur. Furthermore, the moisture will not be stored inside the solenoid valve block, avoiding the problems of the solenoid valve block becoming ineffective due to internal rusting and icing, and the ECAS system failing to adjust the vehicle body height.

[0011] Additional aspects and advantages of the utility model will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the water-proof structure of the solenoid valve block according to an embodiment of the utility model.

[0015] The embodiments of the utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model and should not be construed as a limitation of the utility model.

[0016] As Figure 1 shown, a water-proof structure of a solenoid valve block proposed in this embodiment includes an air compressor assembly 1 and a solenoid valve block 3. The air outlet 1.1 of the air compressor assembly 1 and the air inlet 3.1 of the solenoid valve block 3 are connected through a high-pressure pipe 2. The air inlet 3.1 of the solenoid valve block is higher than the air outlet 1.1 of the air compressor in the positive Z-axis direction and the vertically upward direction.

[0017] Among them, both ends of the high-pressure pipe 2 are respectively connected to the air outlet 1.1 of the air compressor and the air inlet 3.1 of the solenoid valve block through quick connectors. Of course, other connecting parts can also be used, depending on the actual situation.

[0018] Thus, by setting the air inlet 3.1 of the solenoid valve block to be higher than the air outlet 1.1 of the air compressor in the positive Z-axis direction and the vertically upward direction, when condensate appears in the solenoid valve block 3, due to the action of gravity, the condensate flows out from the air inlet 3.1 of the solenoid valve block, enters the air outlet 1.1 of the air compressor through the high-pressure pipe 2, and finally enters the interior of the air compressor assembly 1. Inside the air compressor assembly 1, due to the presence of a dryer, there is a certain space for absorbing and storing moisture. Therefore, when moisture enters the interior of the air compressor dryer, no failure will occur, and further, the moisture will not be stored inside the solenoid valve block, avoiding the problems of the solenoid valve block becoming ineffective due to internal rusting and icing and the ECAS system failing to adjust the vehicle body height.

[0019] Furthermore, in order to ensure that all the condensate in the solenoid valve block 3 flows smoothly into the interior of the air compressor assembly 1, the air inlet 3.1 of the solenoid valve block is at the lowest point of the solenoid valve block 3. When condensate appears in the solenoid valve block 3, due to the action of gravity, the condensate can flow smoothly out from the air inlet 3.1 at the lowest point, enter the air outlet 1.1 of the air compressor through the high-pressure pipe 2, and finally enter the interior of the air compressor assembly 1.

[0020] Even further, the direction of the high-pressure pipe 2 between the connection end at the air inlet 3.1 of the solenoid valve block and the connection end at the air outlet 1.1 of the air compressor is in the negative Z-axis direction and the vertically downward direction. This facilitates the flow of condensate from the air inlet 3.1 of the solenoid valve block to the air outlet 1.1 of the air compressor.

[0021] In summary, since the present embodiment is provided with a structure for preventing water from entering the solenoid valve block, the possibility of water entering the solenoid valve block 3 is greatly reduced; since the possibility of water entering the solenoid valve block 3 is greatly reduced, the problems of the solenoid valve block becoming ineffective due to internal rusting and icing and the ECAS system failing to adjust the vehicle body height are avoided.
