Description

Technical Field

[0001] This application relates to the field of fluid control technology, specifically to a valve box device. Background Technology

[0002] The valve housing assembly includes a housing, which comprises a main body housing and an electrical interface housing. The main body housing is used to mount the control valve, while the electrical interface housing is used to connect to signal cables. In related technologies, the main body housing and the electrical interface housing are manufactured separately and then assembled, resulting in relatively low production and assembly efficiency.

[0003] Therefore, how to provide a solution that can improve the production and assembly efficiency of valve box devices remains a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this application is to provide a valve box device that has relatively high production and assembly efficiency and relatively good assembly consistency.

[0005] To solve the above-mentioned technical problems, this application provides a valve box device, including a housing, at least two control valves and an electrical connector, wherein the at least two control valves and the electrical connector are electrically connected, the housing includes a main body shell and an electrical interface shell, the wall of the main body shell forms at least a portion of a first accommodating space, the at least two control valves are located in the first accommodating space, the electrical connector and the electrical interface shell are limited or fixedly arranged, and the main body shell and the electrical interface shell are integrally formed as a single structure.

[0006] In the above solution, the main body shell and the electrical interface shell are integrally molded structures, meaning they are connected during the molding process. This eliminates the need for reassembly in related technologies, simplifying the valve box assembly production process and improving production and assembly efficiency. Furthermore, it facilitates ensuring the relative positional accuracy and structural stability between the main body shell and the electrical interface shell, which is beneficial for improving the assembly consistency of different batches of valve box assemblies.

Detailed Implementation

[0009] To enable those skilled in the art to better understand the technical solutions of this application, the specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0010] Please refer to Figures 1-5 , Figure 1 This is a schematic diagram of the connection structure of the housing, control valve, and circuit board in a valve box device provided in an embodiment of this application; Figure 2 for Figure 1 A schematic diagram of the middle shell structure from one perspective; Figure 3 for Figure 1 A schematic diagram of the middle shell from another perspective; Figure 4 for Figure 1 A schematic diagram of the middle shell from another perspective; Figure 5 This is a schematic diagram of the structure of a valve box device provided in an embodiment of this application.

[0011] like Figures 1-5 As shown in the figure, this application provides a valve box device that can be applied to devices requiring air path control, flow path switching, or pressure regulation, such as an air suspension system in a vehicle, to inject or discharge gas into the airbags of different air springs. The valve box device includes a housing 1000, at least two control valves 2000, and electrical connectors (not shown in the figure).

[0012] The housing 1000 is the main structure of the valve box assembly, providing a mounting base for the control valve 2000, circuit board 3000, electrical connectors, and other related structural components. The control valve 2000 is mounted in the housing 1000 and cooperates with the airflow passage within the housing 1000 to achieve airflow interruption, gas flow direction switching, or other air path control functions. The control valve 2000 can be a solenoid valve or any other valve structure capable of changing its operating state according to a control signal; no limitation is made here. The electrical connectors can be electrically connected to each control valve 2000, and can also be electrically connected to external control equipment via external signal cables, external connectors, or other external connectors to achieve signal transmission between the control valve 2000 and the external control equipment.

[0013] Specifically, the housing 1000 includes a main housing portion 1100 and an electrical interface housing portion 1200. The walls of the main housing portion 1100 can enclose at least a portion of a first receiving space 1100A, through which at least two control valves 2000 are located for assembly. The walls of the electrical interface housing portion 1200 can enclose a second receiving space 1200A, in which an electrical connector can be at least partially located, and can be limited or fixed within the electrical interface housing portion 1200 to fix the position of the electrical connector.

[0014] As described in the background section, in related technologies, the main body shell and the electrical interface shell are often manufactured separately and then connected together through an assembly process. This not only increases the assembly steps between the main body shell and the electrical interface shell, but also requires consideration of issues such as connection stability, sealing performance, and assembly errors, resulting in relatively low production and assembly efficiency for the valve box device.

[0015] Based on this, the embodiments of this application set the main body shell 1100 and the electrical interface shell 1200 as an integrally formed structure.

[0016] In other words, the main body shell 1100 for accommodating the control valve 2000 and the electrical interface shell 1200 for mounting electrical connectors can be directly formed during the molding of the housing 1000. This reduces the reassembly process of the main body shell and the electrical interface shell in related technologies, making the production process of the valve box device simpler and improving the production and assembly efficiency of the valve box device. At the same time, it is also easier to ensure the relative positional accuracy and structural stability between the main body shell 1100 and the electrical interface shell 1200, which has a relatively positive significance for improving the assembly consistency of valve box devices of different batches.

[0017] Here, the embodiments of this application do not limit the specific molding process of the housing 1000. In practical applications, those skilled in the art can determine the process based on the material and other relevant requirements of the housing 1000. For example, the housing 1000 can be formed by a one-piece injection molding process, where the main housing 1100 and the electrical interface housing 1200 can be injection molded in the same mold, so that the two remain as a one-piece structure that is not easily separated after molding. Alternatively, the housing 1000 can also be integrally molded using additive manufacturing (AM) processes such as fused deposition modeling (FDM) and stereolithography apparatus (SLA).

[0018] In some implementations, such as Figure 2 As shown, a first reinforcing part 1300 is provided on the inner side of the housing 1000, and the first reinforcing part 1300 is distributed at least at the connection between the main housing part 1100 and the electrical interface housing part 1200.

[0019] In actual use, the electrical interface housing 1200 is subject to its own weight, the weight of related components such as electrical connectors located on the electrical interface housing 1200, and the forces generated by the insertion, removal, or pulling of external connectors. This makes the connection between the electrical interface housing 1200 and the main housing 1100 prone to breakage or other forms of damage. Therefore, this embodiment of the application also selects to provide a first reinforcing part 1300 on the inner side of the housing 1000 to reinforce the connection between the main housing 1100 and the electrical interface housing 1200 from the inside of the housing 1000. This allows the connection to better withstand the aforementioned forces and is less prone to damage, effectively improving the quality and service life of the valve box device provided in this embodiment of the application.

[0020] It should be understood that the inner side of the housing 1000 refers to the side of the housing 1000 facing the first receiving space 1100A and the second receiving space 1200A.

[0021] Here, the embodiments of this application do not limit the specific structural form of the first reinforcing part 1300 described above. In practical applications, those skilled in the art can make selections according to specific needs. For example, see... Figure 2The first reinforcing part 1300 may include a plurality of spaced-apart first reinforcing plates 1310. On the one hand, this can effectively reinforce the connection between the main body shell 1100 and the electrical interface shell 1200. On the other hand, it can avoid the defects such as material waste and increased weight caused by making the connection point thicker as a whole. For example, the first reinforcing part 1300 may include a plurality of first reinforcing plates 1310, and the first reinforcing plates 1310 can be connected to each other to form a grid-like interwoven structure, which can further improve the reinforcing effect.

[0022] In specific manufacturing processes, the first reinforcing part 1300 can be integrally formed with the housing 1000. This reduces the reassembly process between the two and further improves the production and assembly efficiency of the valve box device provided in this embodiment. Alternatively, the first reinforcing part 1300 can be manufactured separately and then assembled by welding, bonding, or other methods, which is also feasible.

[0023] In some implementations, such as Figure 3 As shown, a second reinforcing part 1400 is also provided on the outer side of the housing 1000. The second reinforcing part 1400 is distributed at least at the connection between the main housing part 1100 and the electrical interface housing part 1200.

[0024] The second reinforcing part 1400 can reinforce the connection between the main body shell 1100 and the electrical interface shell 1200 from the outside of the housing 1000, so that the connection can withstand various forms of force and is not easily damaged, which can effectively improve the quality and service life of the valve box device provided in the embodiments of this application.

[0025] It should be understood that the outer side of the housing 1000 refers to the side of the housing 1000 that is away from the first receiving space 1100A and the second receiving space 1200A.

[0026] Here, the embodiments of this application do not limit the specific structural form of the second reinforcing part 1400 described above. In practical applications, those skilled in the art can make selections according to specific needs. For example, see... Figure 3 The second reinforcing part 1400 may include a plurality of spaced-apart second reinforcing plates 1410. On the one hand, this effectively strengthens the connection between the main body shell 1100 and the electrical interface shell 1200. On the other hand, it avoids the material waste and increased weight caused by making the connection point thicker overall. For example, the second reinforcing part 1400 may include a plurality of second reinforcing plates 1410, which can be interconnected to form a mesh-like interwoven structure, thus achieving a better reinforcing effect.

[0027] In specific manufacturing processes, the second reinforcing part 1400 can be integrally formed with the housing 1000. This reduces the reassembly process between the two and further improves the production and assembly efficiency of the valve box device provided in this embodiment. Alternatively, the second reinforcing part 1400 can be manufactured separately and then assembled by welding, bonding, or other methods, which is also feasible.

[0028] It should be understood that in the embodiments of this application, the first reinforcing part 1300 and the second reinforcing part 1400 may be provided selectively to simplify the structural form of the valve box device provided in the embodiments of this application; or, the first reinforcing part 1300 and the second reinforcing part 1400 may both be provided to increase the reinforcement effect at the connection between the main body shell 1100 and the electrical interface shell 1200.

[0029] In some implementations, such as Figure 1 and Figure 2 As shown, the main body shell 1100 includes a shell sidewall 1110 and a limiting part 1120.

[0030] The shell sidewall 1110 can enclose at least a portion of the boundary of the first receiving space 1100A. The limiting part 1120 is provided on the shell sidewall 1110 and can be used to limit the control valve 2000, thereby reducing the shaking or swaying of the control valve 2000 when the shell 1000 is transferred, flipped or vibrated.

[0031] Specifically, the limiting part 1120 includes a first protrusion 1121, which protrudes from the inner wall surface of the shell sidewall 1110, where the inner wall surface refers to the wall surface of the shell sidewall 1110 facing the first receiving space 1100A. The number of first protrusions 1121 is at least two, and each first protrusion 1121 is spaced apart.

[0032] In some designs, the control valve 2000 has a first protrusion 1121 on both sides, and both protrusions 1121 can abut against the wall of the control valve 2000. This allows the control valve 2000 to be confined between the two protrusions 1121, which can clamp and position the control valve 2000. In other designs, at least one control valve 2000 may have the aforementioned first protrusion 1121 on only one side. In this case, the first protrusion 1121 can only confine the control valve 2000 on one side, while the other sides can be confined by the shell sidewall 1110 or other limiting structures. In summary, by placing the first protrusion 1121 on one or both sides of the control valve 2000 and making the first protrusion 1121 abut against the wall of the control valve 2000, the control valve 2000 can be effectively supported and limited. This reduces the possibility of the control valve 2000 shaking or swaying during potting, transportation, or use, which helps to ensure the stable and accurate assembly of the control valve 2000 and improves the assembly consistency and operational reliability of the control valve 2000 in the valve box device.

[0033] In some implementations, such as Figures 1-4 As shown, the limiting part 1120 may also include a first recessed part 1122. The first recessed part 1122 is recessed in the outer wall surface of the shell sidewall 1110 in the area corresponding to the first protrusion 1121. Here, the outer wall surface refers to the wall surface of the shell sidewall 1110 that is away from the first receiving space 1100A.

[0034] In other words, at the location where the first protrusion 1121 is formed on the inner side of the shell sidewall 1110, a corresponding first recess 1122 can be formed on the outer side of the shell sidewall 1110. This configuration allows for the formation of a protruding structure for the limit control valve 2000 on the inner side of the shell sidewall 1110; it also reduces the wall thickness of the shell sidewall 1110 in the area where the first protrusion 1121 is located. For the injection-molded shell 1000, the first recess 1122 improves the uniformity of the wall thickness of the shell sidewall 1110, reducing phenomena such as bulging and shrinkage at the first protrusion 1121 during injection molding. This enhances the dimensional accuracy and processing quality of the first protrusion 1121, thus ensuring its limiting effect.

[0035] In some implementations, such as Figure 1 As shown, a circuit board 3000 is installed inside the housing 1000, and the circuit board 3000 is electrically connected to the control valve 2000 and the electrical connector.

[0036] The circuit board 3000 can be a printed circuit board (PCB), on which electrical connection lines, control components, conductive terminals, or other electronic components are provided. External control signals can be transmitted to the circuit board 3000 via electrical connections, and then from the circuit board 3000 to the corresponding control valve 2000, thereby controlling the opening, closing, or other working states of the corresponding control valve 2000.

[0037] Combination Figure 1 and Figure 2 The main body shell 1100 includes a support portion 1130, which includes a second protrusion 1131. The second protrusion 1131 protrudes from the inner wall surface of the shell sidewall 1110 and abuts against the circuit board 3000. After the circuit board 3000 is installed inside the shell 1000, it forms an abutment fit with the edge area or other areas of the circuit board 3000, thereby supporting the circuit board 3000 and keeping it at a predetermined height or in a predetermined installation posture. This reduces the possibility of the circuit board 3000 sinking, tilting, or other changes in posture or position. In other words, it improves the positioning reliability of the circuit board 3000, which helps to ensure the reliability of the electrical connection between the circuit board 3000 and the control valve 2000 and the electrical connectors.

[0038] In the specific design, the number of second protrusions 1131 can be one. Alternatively, the number of second protrusions 1131 can also be multiple. Multiple second protrusions 1131 can be arranged at intervals along the outer periphery of the circuit board 3000 to form multi-point support for the circuit board 3000, thereby improving the support reliability of the circuit board 3000 to a greater extent.

[0039] In some implementations, such as Figure 1 , Figure 3 and Figure 4 As shown, the support portion 1130 may also include a second recessed portion 1132. The second recessed portion 1132 is recessed in the outer wall surface of the shell sidewall 1110 in the area corresponding to the second protrusion 1131. Here, the outer wall surface refers to the wall surface of the shell sidewall 1110 that is away from the first receiving space 1100A.

[0040] In other words, at the location where the second protrusion 1131 is formed on the inner side of the shell sidewall 1110, a corresponding second recess 1132 can be formed on the outer side of the shell sidewall 1110. This arrangement allows for the formation of a protruding structure on the inner side of the shell sidewall 1110 to support the circuit board 3000; it also reduces the wall thickness of the shell sidewall 1110 in the area where the second protrusion 1131 is located. For the injection-molded shell 1000, the second recess 1132 improves the uniformity of the wall thickness of the shell sidewall 1110, reducing phenomena such as bulging and shrinkage at the second protrusion 1131 during injection molding. This enhances the dimensional accuracy and processing quality of the second protrusion 1131, thus ensuring its support and positioning effect.

[0041] In some implementations, such as Figure 5 As shown, the valve box device also includes a filling part 4000, which fills the first receiving space 1100A and the second receiving space 1200A.

[0042] The filler portion 4000 can be a cured structure formed after potting. The circuit board 3000 and the control valve 2000 are distributed along the axial direction of the valve core of the control valve 2000. The filler portion 4000 covers the control valve 2000 and the circuit board 3000 along the axial direction of the valve core. After the filler portion 4000 is formed, the control valve 2000 and the circuit board 3000 can maintain a stable installation state under the action of the filler portion 4000, thereby meeting the fixation requirements of the control valve 2000 and the circuit board 3000 during long-term use of the valve box device.

[0043] Here, the specific material of the filling part 4000 is not limited in this application embodiment, as long as it can fix the control valve 2000 and circuit board 3000 after filling, and can meet the relevant requirements of sealing, insulation, vibration resistance or structural protection of the valve box device.
