Description

Technical Field

[0001] The present application relates to the technical field of solenoid valves, and in particular to a combined solenoid valve. Background Art

[0002] Solenoid valves are electromagnetically controlled industrial devices, essential automation components for controlling fluids. They are classified as actuators, not limited to hydraulic or pneumatic systems. They are used in industrial control systems to adjust the direction, flow, speed, and other parameters of media. Solenoid valves can be combined with various circuits to achieve desired control, ensuring both precision and flexibility. There are many different types of solenoid valves, each serving different functions within a control system. The most commonly used are check valves, safety valves, directional control valves, and speed control valves.

[0003] In some application scenarios, the coordination of multiple solenoid valves is required. For example, the seat ventilation function in some cars requires multiple solenoid valves to work together to control the airflow. At present, the assembly method of multiple solenoid valves generally involves first docking the coil frames of each unit with the coil frames, or docking the air nozzle with the coil frame. After the overall docking is completed, a large outer frame is used to limit the entire structure to achieve the assembly of multiple solenoid valves. There are some problems with this method. The connection stability of adjacent solenoid valves is not high. Since multiple valve bodies are assembled and then fixed and limited, the internal connection stability is not high. Secondly, during subsequent inspection and maintenance, the entire structure needs to be disassembled, which also has certain inconveniences in disassembly and maintenance. Utility Model Content

[0044] Example

[0045] In some application scenarios, the coordination of multiple solenoid valves is required. For example, the seat ventilation function in some cars requires the coordination of multiple solenoid valves to achieve airflow control. At present, the assembly method of multiple solenoid valves generally involves first docking the coil frames of each unit with the coil frames, or docking the air nozzle with the coil frame. After the overall docking is completed, a large outer frame is used to limit the entirety to achieve the assembly of multiple solenoid valves. This method has the following problems: the connection stability of adjacent solenoid valves is not high. Since multiple valve bodies are assembled and then fixed and limited, the internal connection stability is not high. Secondly, in subsequent inspection and maintenance, the entire valve needs to be disassembled, which also causes certain inconveniences in disassembly and maintenance.

[0046] In order to solve the above technical problems, this embodiment provides the following technical solutions:

[0047] For details, see Figure 1-5 , this embodiment provides a combined solenoid valve, comprising a first valve body unit 10;

[0048] The first valve body unit 10 includes a first coil frame 11, a first coil assembly 12, and a first air nozzle 13. A first plug connector 15 and a first socket 14 are provided on the first coil frame 11. The first plug connector 15 of a first valve body unit 10 is adapted to be inserted into the first socket 14 of an adjacent first valve body unit 10. The first plug connector 15 and the first socket 14 of the same valve body unit form a communicating airflow channel (not shown).

[0049] It should be noted that some of the structures of the valve body unit in this embodiment, such as the electrical connection structure, are the same as or similar to those of traditional conventional solenoid valves. The main invention point in this application lies in how to achieve rapid assembly and connection of multiple solenoid valves, that is, it mainly lies in the connection structure. Therefore, this application will not further elaborate on the parts related to the main functional structure of the solenoid valve, but it should be understood that it does not affect the understanding of the overall solution by those skilled in the art.

[0050] Specifically, the first plug connector 15 is formed with a first boss 152 and a second boss 151 formed on the first boss 152. The end of the second boss 151 is formed with a through hole communicating with the air flow channel.

[0051] Specifically, the first socket 14 is formed with a first receiving groove 141 suitable for receiving the first plug connector 15;

[0052] Specifically, a first card slot 1521 is formed on the outer peripheral wall of the first boss 152 , and a second card slot 142 is formed on the outer peripheral wall of the first socket 14 , and the second card slot 142 is communicated with the first receiving slot 141 ;

[0053] Furthermore, it also includes a locking member 30. When the first plug connector 15 is inserted into the first socket 14 and the first slot 1521 is connected to the second slot 142, the locking member 30 is suitable for simultaneously locking into the first slot 1521 and the second slot 142 to prevent the first plug connector 15 from moving away from the first socket 14 along its axial direction.

[0054] In the above scheme, the first valve body unit 10 in this scheme can be understood as an independent and complete solenoid valve. When multiple first valve body units 10 need to be assembled, the two adjacent first valve body units 10 are first docked, and the first plug connector 15 of one of the first valve body units 10 is aligned with the first socket 14 of the other first valve body unit 10. Then, the first plug connector 15 is inserted into the first receiving groove 141 of the first socket 14. When the first card slot 1521 and the second card slot 142 are just aligned, the second card slot 142 can be clamped into the second card slot 142 through the clamping member 30. Since the second card slot 142 is connected to the first receiving groove 141, Therefore, the locking member 30 can be locked into the first slot 1521 at the same time, so as to realize the locking of the first slot 1521 and the second slot 142 at the same time; under the restriction of the locking member 30, the first plug connector 15 and the second plug connector 41 are stably docked; when it is necessary to further splice multiple first valve body units 10, the above operation is repeated; compared with the existing technology, this solution focuses on improving the connection stability of two adjacent first valve body units 10, and adopts the first plug connector 15 and the first socket in combination with the locking member 30 to achieve rapid splicing, simple operation, and improved splicing efficiency; at the same time, it is more conducive to subsequent inspection and maintenance, and improves subsequent maintenance efficiency.

[0055] Specifically, a first sealing ring 153 is sleeved on the outer periphery of the second boss 151;

[0056] Furthermore, the first sealing ring 153 is interference-fitted with the inner wall of the first accommodating groove 141;

[0057] In the above solution, this solution can effectively improve the airtightness of the connection between the first valve body units 10 by providing the first sealing ring 153 on the second boss 151 .

[0058] For details, see Figure 5 , further comprising a second valve body unit 20;

[0059] Specifically, the second valve body unit 20 includes a second coil frame 21, a second coil assembly 23 and a second air nozzle 24;

[0060] Furthermore, a second socket 22 is provided on the second coil frame 21 , and a second receiving groove 221 suitable for receiving the first gas nozzle 13 or the second gas nozzle 24 is formed on the second socket 22 ;

[0061] Specifically, a third slot 131 is formed on the first gas nozzle 13 and the second gas nozzle 24, and a fourth slot 222 communicating with the second accommodating slot 221 is formed on the second socket 22;

[0062] Furthermore, when the first gas nozzle 13 or the second gas nozzle 24 is inserted into the second socket 22 and the third slot 131 is connected to the fourth slot 222, the locking member 30 is adapted to be locked into the third and fourth slots 222 at the same time to prevent the gas nozzle from moving away from the second socket 22 along its axial direction.

[0063] In the above scheme, the connection between the first valve body unit 10 and the first valve body unit 10 can be understood as a horizontal connection, and the connection between the first valve body unit 10 and the second valve body unit 20 or the second valve body unit 20 and the second valve body unit 20 can be understood as a longitudinal connection; taking the connection between the first valve body unit 10 and the second valve body unit 20 as an example, the first gas nozzle 13 on the first valve body unit 10 can be extended into the second accommodating groove 221 of the second socket 22, and a third card groove 131 is formed on the first gas nozzle 13 and the second gas nozzle 24, and the third card groove 131 is formed on the second gas nozzle 13 and the second gas nozzle 24. A fourth slot 222 is formed on the connector 22. When the third slot 131 is inserted into the corresponding fourth slot 222, the locking member 30 can be inserted into the third slot 131 and the fourth slot 222. The specific principle can refer to the cooperation between the first slot 1521 and the second slot 142 and the locking member 30; similarly, the connection principle of the two second valve body units 20 is the same, that is, the second air nozzle 24 of one second valve body unit 20 can be inserted into the second connector 22 of the next second valve body unit 20, and then fixed by the locking member 30.

[0064] For details, see Figure 2 and Figure 4 A second sealing ring 132 is provided on the outer peripheral wall of the first gas nozzle 13 and the second gas nozzle 24 . The second sealing ring 132 is suitable for interference fit with the inner wall of the second accommodating groove 221 .

[0065] In the above solution, the present solution further provides a second sealing ring 132 on the first gas nozzle 13 and the second gas nozzle 24, which can increase the airtightness between the first gas nozzle 13 or the second gas nozzle 24 and the second accommodating groove 221, thereby improving the airtightness of the connection between adjacent valve bodies.

[0066] Specifically, a first air duct 17 communicating with the air flow channel is provided on the first coil frame 11 .

[0067] For details, see Figure 1-3 , further comprising an elbow frame 40, on which a second plug connector 41 or a third plug socket is formed, and a second air guide pipe 43 communicating with the second plug connector 41 or the third plug socket is further provided on the elbow frame 40;

[0068] Furthermore, the second plug connector 41 is adapted to be inserted into the first plug socket 14 , and the first plug connector 15 is adapted to be inserted into the third plug socket or the first plug socket 14 ;

[0069] In the above solution, the structure of the third socket can refer to the first socket 14 or the second socket 22, and the structure of the second plug connector 41 can refer to the first plug connector 15; the elbow frame 40 in this solution can be set on both sides of the entire combined solenoid valve.

[0070] For further information, see Figure 3 A third sealing ring 42 is provided on the second plug connector 41; the third sealing ring 42 is interference fit with the inner wall of the third plug socket.

[0071] Specifically, in one embodiment, the retaining member 30 includes a U-shaped retaining spring;

[0072] In the above scheme, this scheme uses a U-shaped retaining spring as the locking member 30, which has a certain elasticity and can achieve a certain clamping through elasticity, thereby achieving a more stable locking effect; at the same time, the U-shaped structure is simple in structure and easy to process, so the cost is lower, and it can achieve the clamping function, and it is also very convenient when assembling.

[0073] It is understandable that the U-shaped retaining spring is only one of the ways to achieve the above-mentioned clamping connection. In actual applications, it can also be a structure of other shapes, and this application does not limit this.

[0074] For details, see Figure 3 A fixing seat 16 is provided on the first socket 14 and the second socket 22 respectively. A buckle groove 161 is formed on the fixing seat 16. The positioning member 30 is suitable for being snapped into the buckle groove 161.

[0075] In the above scheme, when assembling the locking member 30, the locking member 30 itself can be locked into the snap groove 161, so as to fix the locking member 30 itself to the first socket 14 or the second socket 22, thereby realizing the problem of self-assembly. At the same time, it cooperates with the first slot 1521 and the second slot 142 to realize the locking function of the first plug connector 15 and the first socket 14.

[0076] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application fall within the scope of the technical solution of the present application.
