In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0021] Please refer to Figures 1-4 , Figure 1 A schematic structural diagram of an implementation of a valve box device provided in an embodiment of the present invention; Figure 2 for Figure 1 A front view of the invention, wherein part of the housing and the solenoid valve are partially sectioned; Figure 3 for Figure 2 A partial view of Figure 4 for Figure 1 , in which the interior of the shell body is schematically illustrated.

[0022] like Figures 1-4 As shown, the present invention provides a valve box device, which can be specifically applied to vehicles and can detect the internal pressure of the suspension system, thereby adjusting the inflation and exhaust of air springs, air tanks, etc. in the suspension system. The valve box device includes a housing 1000, a solenoid valve 2000, a pressure detection component 3000, an electronic control component 4000, and a junction box 6000.

[0023] The housing 1000 is the structural basis of the valve box device. Other components can be directly or indirectly installed on the housing 1000 so as to be integrated through the housing 1000. At the same time, the housing 1000 also basically determines the external shape of the valve box device. In the specific implementation, the structural shape of the housing 1000 can refer to Figure 1 Alternatively, those skilled in the art can make adjustments on their own as long as the requirements of use are met.

[0024] The housing 1000 includes a housing body 1100 , a connecting portion 1200 , a flow guide portion 1300 , and a connector 1400 .

[0025] The shell body 1100 may include a bottom plate 1110 and a peripheral plate 1120, and the peripheral plate 1120 may be located on the normal side of the bottom plate 1110. The bottom plate 1110 and the peripheral plate 1120 may be an integrally formed one-piece structure, such as integral injection molding, in order to simplify the molding process. Alternatively, the bottom plate 1110 and the peripheral plate 1120 may be prepared separately and then assembled. The specific assembly method may be, for example, welding, bonding, riveting, screw connection, etc., which is not limited here, as long as it can meet the relevant requirements such as the reliability of the connection. The bottom plate 1110 and the peripheral plate 1120 can enclose to form a accommodating cavity 1130, and the solenoid valve 2000, the pressure detection component 3000 and the electronic control component 4000 can all be arranged in the accommodating cavity 1130.

[0026] The connecting portion 1200 may be located on the side of the bottom plate 1110 that is away from the peripheral plate 1120 in the normal direction, and the air guide portion 1300 is located on the side of the connecting portion 1200 that is away from the housing 1000. Figure 3 As shown, the connecting part 1200 has a connecting cavity 1210, and the guide part 1300 has a guide cavity 1310; the guide part 1300 is also provided with a connecting channel 1320, one end of the connecting channel 1320 is connected to the guide cavity 1310, and the other end of the connecting channel 1320 forms a valve port 1321, and the valve port 1321 is connected to the connecting cavity 1210.

[0027] The solenoid valve 2000 includes a valve body 2100 and a valve core 2200. The valve body 2100 is disposed within the accommodating chamber 1130. The valve core 2200 is mounted on the valve body 2100 and is movable relative to the valve body 2100. A portion of the valve core 2200 can also extend into the communication chamber 1210. When the valve core 2200 moves relative to the valve body 2100, the valve core 2200 can open or block the valve port 1321, thereby connecting or blocking the communication chamber 1210 and the diversion chamber 1310.

[0028] With this arrangement, the embodiment of the present invention utilizes the connecting cavity 1210 of the connecting portion 1200 as the valve cavity, and utilizes the connecting channel 1320 of the flow guide portion 1300 as the valve port channel, allowing the valve port 1321 to be formed directly in the flow guide portion 1300. This means that a portion of the housing 1000 can function as at least a portion of the valve body of a conventional solenoid valve. This allows the structure of the solenoid valve 2000 in the embodiment of the present invention to be relatively simple, with a relatively small number of components. This significantly simplifies the structure and assembly process of the solenoid valve 2000 and the valve box assembly, reducing assembly time, difficulty, and cost.

[0029] In an embodiment of the present invention, plug connector 1400 may be located in flow guide portion 1300 and communicate with flow guide cavity 1310. There may be multiple plug connectors 1400. Each plug connector 1400 may be equipped with a cap (not shown) to prevent dust. In actual use, the cap can be replaced with a connecting hose, etc., to facilitate connection to external equipment such as a compressor, air spring, or air tank.

[0030] The pressure detection component 3000 may specifically be a pressure sensor, etc., which has a pressure collection end. The pressure collection end may be in contact with the fluid in the guide cavity 1310 to monitor the pressure signal.

[0031] The electronic control component 4000 can be a printed circuit board (PCB), which can be provided with corresponding control circuits, etc. The pressure detection component 3000 and the solenoid valve 2000 can both be electrically connected to the electronic control component 4000. The junction box 6000 can also be electrically connected to the electronic control component 4000, and the junction box 6000 can also be electrically connected to an external control unit.

[0032] In practical applications, the valve box device provided in the embodiment of the present invention may have an inflation mode, an exhaust mode, and a pressure holding mode.

[0033] In the inflation mode, the valve body 2100 can control the valve core 2200 to be relatively away from the valve port 1321. At this time, the valve port 1321 can be in an open state, and the communication cavity 1210 and the diversion cavity 1310 can be connected. External gas can enter the communication cavity 1210 and enter the corresponding air spring or air tank through the corresponding plug connector 1400 for inflation.

[0034] In exhaust mode, the valve body 2100 can control the valve core 2200 to be relatively away from the valve port 1321. At this time, the valve port 1321 can be in an open state, and the connecting chamber 1210 and the guide chamber 1310 can be connected. The gas in the air spring or air tank can enter the connecting chamber 1210 through the corresponding plug connector 1400. Then, the gas can enter the guide chamber 1310 through the connecting channel 1320 and be discharged to the outside world through the compressor for exhaust.

[0035] In the pressure holding mode, the valve body 2100 can control the valve core 2200 to be relatively close to the valve port 1321. At this time, the valve port 1321 can be in a blocked state. The gas in the air spring or the gas tank cannot pass through the solenoid valve 2000, thereby achieving the pressure holding function.

[0036] In some optional implementations, the flow guide 1300 can be an integrally formed structure, such as an integral injection molded structure. In this way, the communication channel 1320 and the valve port 1321 can be integrally formed with the flow guide 1300, making the communication channel 1320 and the valve port 1321 relatively easy to manufacture.

[0037] In fact, the entire housing 1000 can be a one-piece structure formed in one piece, such as by integral injection molding, making the entire housing 1000 relatively easy to manufacture. Of course, in the housing 1000, at least part of the housing body 1100, the connecting portion 1200, the flow guide portion 1300, and the plug connector 1400 can be manufactured separately and then connected to the other parts by welding, riveting, bonding, screw connection, etc. This is also feasible.

[0038] In the embodiment of the present invention, the housing 1000 may be made of plastic.

[0039] In some optional implementations, the valve body 2100 and the bottom plate 1110 may be sealed to reduce the possibility of fluid leakage between the valve body 2100 and the bottom plate 1110 .

[0040] The valve body 2100 and the bottom plate 1110 may be connected by screws or the like. The valve box device provided in the embodiment of the present invention may further include a sealing component 5000 , which may specifically be a rubber ring or the like, and may be disposed between the valve body 2100 and the bottom plate 1110 to seal the gap therebetween.

[0041] Specifically, if Figure 3 As shown, the inner wall surface of the connecting part 1200 can be provided with a mounting groove 1220, the mounting groove 1220 can be located at one end of the connecting part 1200 facing the valve body 2100, and the mounting groove 1220 can be connected to the connecting cavity 1210, and the sealing component 5000 can be arranged in the mounting groove 1220 for positioning and assembly through the mounting groove 1220.

[0042] It should be understood that in some other implementations of the present invention, the mounting groove 1220 may not be connected to the communication cavity 1210. Alternatively, the mounting groove 1220 may be provided on the valve body 2100 or provided on both the valve body 2100 and the base plate 1110.

[0043] The valve body 2100 may include a valve seat 2110. The valve seat 2110 may include a seat portion 2111 and a sleeve portion 2112. The seat portion 2111 may be connected to the base plate 1110, and the sealing component 5000 may be disposed between the seat portion 2111 and the base plate 1110. One end of the sleeve portion 2112 may be connected to the seat portion 2111, and the connection method may include welding, interference fit, or a combination of interference fit and welding.

[0044] The valve body 2100 may further include a static iron core 2120 , which may be connected to the other end of the sleeve portion 2112 . The specific connection method may be welding, interference fitting, or a combination of interference fitting and welding.

[0045] The valve core 2200 may include a valve stem 2210 and a plug 2220. The plug 2220 may be mounted on the valve stem 2210 and located on the side of the valve stem 2210 facing away from the static iron core 2120. The plug 2220 may be made of a flexible material such as rubber. The valve core 2200 may be in contact with the valve port 1321 via the plug 2220. This facilitates reliable sealing of the valve port 1321 by the valve core 2200 and reduces wear on the valve port 1321.

[0046] The valve body 2100 may further include an elastic component 2130, which may be disposed between the static iron core 2120 and the valve stem 2210 to provide a restoring force for the valve core 2200. The elastic component 2130 may be a spring, which is readily available in a wide variety of types and models and exhibits relatively good elastic deformation and elastic recovery capabilities. Alternatively, the elastic component 2130 may be another elastic element, such as a bellows, or an elastomer made of a material with a certain degree of elastic deformation, such as rubber or silicone.

[0047] The valve body 2100 may further include a coil component 2140 , and the coil component 2140 may be assembled onto the valve seat 2110 .

[0048] It should be understood that in some other implementations of the present invention, the seat body 2111 and the base plate 1110 can also be connected by welding or bonding. In this case, even if the aforementioned sealing component 5000 is not provided, the seat bottom 2111 and the base plate 1110 can still have relatively good sealing.

[0049] In some optional implementations, the valve box device provided in the embodiment of the present invention may further include a potting portion (not shown in the figures).

[0050] The potting portion can be formed by pouring a potting material. Specifically, the potting process can be performed after the solenoid valve 2000 and the electronic control component 4000 are installed. The potting material can be poured into the accommodating cavity 1130, and then the potting material can be cured to form the potting portion. The potting portion can connect the shell body 1100, the valve body 2100, and the electronic control component 4000, thereby ensuring that the solenoid valve 2000 and the electronic control component 4000 are securely installed and fixed within the housing 1000, and can also protect the solenoid valve 2000 and the electronic control component 4000.

[0051] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
