[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0047] The multi-oil-path adjustable solenoid valve device 100 according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0048] According to an embodiment of the invention, a multi-oil-path adjustable solenoid valve device 100 includes a body 10, eight oil ports, and four solenoid valves.

[0049] Specifically, such as Figures 1 to 3 As shown, the main body 10 has multiple oil passages defined inside. Eight oil ports are respectively located on the outer wall of the main body 10 and connected to the corresponding oil passages. Each of the eight oil ports is combined with another oil port and the corresponding oil passage to form eight sets of oil circuit systems. Each solenoid valve controls the opening and closing between the oil ports of two sets of oil circuit systems. Each oil port is controlled by two solenoid valves.

[0050] In other words, the multi-oil-path adjustable solenoid valve device 100 according to an embodiment of the present invention integrates a complex oil passage switching structure into a single solenoid valve device. It comprises four solenoid valves, each controlling the on / off state of two sets of oil passage systems. Each oil passage system consists of two oil ports and corresponding oil passages, with each oil port involving two sets of oil passage systems. Each oil port is controlled by two solenoid valves, and the on / off state between different oil ports is changed by different combinations of on / off electrical connections of the solenoid valves, thus realizing the connection mode between different oil passages.

[0051] Therefore, the multi-oil-path adjustable solenoid valve device 100 according to the present invention can realize the switching of the on / off state between multiple oil passages through a single solenoid valve device, reducing the complexity of the oil passage layout, reducing the weight of components, and saving overall costs.

[0052] In one embodiment of the present invention, two solenoid valves are normally open solenoid valves, and the other two are normally closed solenoid valves. The normally open solenoid valves are open when de-energized and closed when energized, while the normally closed solenoid valves are closed when de-energized and open when energized. By changing the state of the solenoid valves through energization and de-energization, the free switching between different oil passages can be achieved, making it easy to control.

[0053] Preferably, such as Figure 2 and Figure 3 As shown, the eight oil ports are designated as oil port 11, oil port 12, oil port 13, oil port 14, oil port 15, oil port 16, oil port 17, and oil port 18, and the four solenoid valves are designated as solenoid valve 21, solenoid valve 22, solenoid valve 23, and solenoid valve 24.

[0054] Specifically, one end of the first oil passage 31 is the first oil port 11, and the other end is connected to one end of the first solenoid valve 21; one end of the second oil passage 32 is the second oil port 12, and the other end is connected to the other end of the first solenoid valve 21; one end of the third oil passage 33 is the third oil port 13, and the other end is connected to one end of the second solenoid valve 22; one end of the fourth oil passage 34 is the fourth oil port 14, and the other end is connected to the other end of the second solenoid valve 22; one end of the fifth oil passage 35 is the fifth oil port 15, and the other end is connected to one end of the third solenoid valve 23; one end of the sixth oil passage 36 is... The sixth oil port 16 is connected to the other end of the third solenoid valve 23; one end of the seventh oil passage 37 is the seventh oil port 17, and the other end is connected to one end of the fourth solenoid valve 24; one end of the eighth oil passage 38 is the eighth oil port 18, and the other end is connected to the other end of the fourth solenoid valve 24; the ninth oil passage 39 connects the first oil port 11 and the third oil port 13; the tenth oil passage 40 connects the fourth oil port 14 and the fifth oil port 15; the eleventh oil passage 31 connects the second oil port 12 and the seventh oil port 17; and the twelfth oil passage 42 connects the sixth oil port 16 and the eighth oil port 18.

[0055] Furthermore, the first solenoid valve 21 and the third solenoid valve 23 are normally open solenoid valves, and the second solenoid valve 22 and the fourth solenoid valve 24 are normally closed solenoid valves.

[0056] Specifically, the first solenoid valve 21 is a normally open solenoid valve, controlling the on / off state of the oil circuit system composed of the first oil port 11 and the seventh oil port 17, and the oil circuit system composed of the second oil port 12 and the third oil port 13; de-energized, it is on; energized, it is off. The second solenoid valve 22 is a normally closed solenoid valve, controlling the on / off state of the oil circuit system composed of the first oil port 11 and the fourth oil port 14, and the oil circuit system composed of the third oil port 13 and the fifth oil port 15; de-energized, it is off; energized, it is on. The third solenoid valve 23 is a normally open solenoid valve, controlling the on / off state of the oil circuit system composed of the fourth oil port 14 and the eighth oil port 18, and the oil circuit system composed of the fifth oil port 15 and the sixth oil port 16; de-energized, it is on; energized, it is off.

[0057] When the first solenoid valve 21, the second solenoid valve 22, the third solenoid valve 23, and the fourth solenoid valve 24 are all de-energized, the first oil port 11, the seventh oil port 17, the second oil port 12, and the third oil port 13 are interconnected; the fourth oil port 14, the eighth oil port 18, the sixth oil port 16, and the fifth oil port 15 are interconnected; and the other oil ports are closed. When the second solenoid valve 22 and the fourth solenoid valve 24 are de-energized, and the first solenoid valve 21 and the third solenoid valve 23 are energized, the first oil port 11 and the third oil port 13 are interconnected; the fourth oil port 14 and the fifth oil port 15 are interconnected; the eighth oil port 18 and the sixth oil port 16 are interconnected; the seventh oil port 17 and the second oil port 12 are interconnected; and the other oil ports are closed. When the second solenoid valve 22 and the fourth solenoid valve 24 are energized, and the first solenoid valve 21 and the third solenoid valve 23 are not energized, the first oil port 11, the second oil port 12, the third oil port 13, the fourth oil port 14, the fifth oil port 15, the sixth oil port 16, the seventh oil port 17 and the eighth oil port 18 are all interconnected.

[0060] Furthermore, such as Figure 3As shown, the first oil port 11, the second oil port 12, the fourth oil port 14 and the sixth oil port 16 are located at the four vertices of a rectangle, and the first oil port 11 and the sixth oil port 16 are located on the same diagonal; the seventh oil port 17, the third oil port 13, the eighth oil port 18 and the fifth oil port 15 are located at the four fixed points of a rectangle, and the seventh oil port 17 and the fifth oil port 15 are located on the same diagonal.

[0061] In other words, the eight oil ports form eight sets of oil circuit systems. Four of these sets include: the first oil port 11 and the seventh oil port 17, located on opposite sides of the main body 10; the second oil port 12 and the third oil port 13, located on opposite sides of the main body 10; the fourth oil port 14 and the eighth oil port 18, located on opposite sides of the main body 10; and the sixth oil port 16 and the fifth oil port 15, located on opposite sides of the main body 10. The other four sets of oil circuit systems include: the first oil port 11 and the fourth oil port 14, located on the same side of the main body 10 and adjacent to each other; the second oil port 12 and the sixth oil port 16, located on the same side of the main body 10 and adjacent to each other; the seventh oil port 17 and the eighth oil port 18, located on the same side of the main body 10; and the third oil port 13 and the fifth oil port 15, located on the same side of the main body 10.
