Description

Technical Field

[0001] The utility model relates to an air supply device for a vehicle suspension. Background Art

[0002] The suspension system of a vehicle is a connection structure system between the vehicle body, frame and wheels, which is mainly composed of elastic elements, guide mechanisms, shock absorbers, buffer blocks and lateral stabilizer bars. Its function is to transmit the force and torque acting between the wheels and the frame, and to buffer the impact force transmitted to the frame or body by the uneven road surface, and to attenuate the vibration caused thereby, so as to ensure that the car can run smoothly. The suspension system can be divided into passive suspension system and active suspension system according to different control forms; it can be divided into independent suspension system and non-independent suspension system according to different vehicle guide mechanisms. Different suspension settings will give the driver different driving experience. The suspension system integrates multiple forces, determines the stability, comfort and safety of the car, and is one of the most critical components of modern cars.

[0003] The air supply device of the vehicle suspension is used to provide a stable and reliable air source for the vehicle's electronically controlled suspension system. By precisely controlling the supply of gas, it ensures that the suspension system can achieve the best suspension effect under different road conditions and driving conditions. For example, the suspension air supply device can adjust the pressure and flow of the gas according to the vehicle's driving state and the driver's needs, thereby adjusting the height of the vehicle. More specifically, when driving at high speeds, it can lower the height of the vehicle body, reduce wind resistance and fuel consumption; and under complex road conditions, it can increase the height of the vehicle body to enhance the vehicle's passability and stability.

[0004] Therefore, the air supply device of the vehicle suspension is an indispensable part of the electronically controlled suspension system, and it is of great significance to improve the driving performance and ride comfort of the vehicle. The working mechanism of the vehicle suspension air supply device mainly depends on the synergy with other vehicle systems, especially the close cooperation with the electronic control unit (ECU) and sensors. The control unit controls the operation of the air compressor to generate the required gas pressure, and accurately controls the flow direction and flow of the gas through components such as solenoid valves, opening and closing within a fixed time to ensure that the gas in and out of the airbag reaches the best state, thereby achieving precise adjustment of the vehicle body height. By adjusting the gas pressure and flow, the vehicle can achieve the best suspension effect under different road conditions and driving conditions, thereby improving driving performance and ride comfort.

[0005] However, in the common suspension control modules in the prior art, solenoid valves with different functions are usually scattered throughout the vehicle, which brings many inconveniences to the control and assembly work. There are also some solutions that relatively centrally arrange multiple solenoid valves involved in the suspension system, but they still separate the valve core and coil of the solenoid valve and respectively set them on the solenoid valve body and the external controller, which causes inconvenience to the assembly work and will bring additional assembly errors. The arrangement of the solenoid valve coil in the controller is also not conducive to the heat dissipation of the controller, thus bringing hidden dangers of failure to the suspension system.

[0006] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides an air supply device, a suspension system and a vehicle for a vehicle suspension. The air supply device assembles a plurality of solenoid valves with different functions for the suspension system into one, with a higher degree of integration. At the same time, it can achieve higher process accuracy and assembly accuracy requirements, avoid process errors caused by the dispersed assembly of solenoid valves, facilitate the assembly process, save process costs, and improve the heat dissipation performance of the device to ensure the reliable operation of the vehicle suspension.

In order to provide an in-depth understanding of the present utility model, the following description will include many specific details. The present utility model can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present utility model, some specific details will be omitted in the description.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In addition, the terms "upper", "lower", "left", "right", "top", "bottom", "horizontal" and "vertical" used in the following description should be understood as the directions shown in the paragraph and the related drawings. Such relative terms are only used for the convenience of description and do not mean that the device described therein must be manufactured or operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0046] It is understood that although the terms "first", "second", "third", etc. may be used herein to describe various components, regions, layers and / or parts, these components, regions, layers and / or parts should not be limited by these terms, and these terms are only used to distinguish different components, regions, layers and / or parts. Therefore, the first component, region, layer and / or part discussed below may be referred to as the second component, region, layer and / or part without departing from some embodiments of the present invention.

[0047] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides an air supply device, a suspension system and a vehicle for a vehicle suspension. The air supply device centrally assembles multiple solenoid valves with different functions for the suspension system inside an integrated air circuit module, which has a higher degree of integration and can achieve higher process accuracy and assembly accuracy requirements, thereby avoiding process errors caused by the dispersed assembly of solenoid valves, facilitating the assembly process and saving process costs. In addition, the use of metal material in the integrated air circuit module also improves the heat dissipation performance of the device, thereby ensuring that the vehicle suspension can continue to work reliably and stably.

[0048] Figure 1 The present invention is a schematic diagram of the structure of an air supply device for a vehicle suspension according to an embodiment of the present invention.

[0049] Please refer to Figure 1 The air supply device 100 of the vehicle suspension provided by the utility model may include: an integrated air circuit module 101, a controller 102, a motor 103 and a dryer 104, wherein Figure 1 As shown, the integrated gas circuit module 101 can be in a regular polyhedron shape, so as to facilitate the assembly and arrangement of other components. Figure 1 The integrated gas circuit module 101 shown has multiple gas channels and multiple electromagnetic valves with different functions integrated therein. The controller 102 , the motor 103 and the dryer 104 can be mounted on different outer surfaces of the integrated gas circuit module 101 , respectively.

[0050] It should be noted that in Figure 1 The embodiment shown is only an exemplary description of the shape of the integrated gas circuit module 101 and the positions of the controller 102, the motor 103 and the dryer 104 respectively mounted on the outer side of the integrated gas circuit module 101, and is not intended to limit the protection scope of the present utility model. In fact, the integrated gas circuit module can be other regular polyhedron shapes, such as hexagonal prisms, etc., and the relative positional relationship between the motor, controller and dryer on its outer side can also be arbitrary, for example, they can be coplanar, placed opposite to each other, or arranged at a predetermined angle to each other.

[0051] Figure 2 The present invention is a schematic diagram of the structure of a solenoid valve in an air supply device for a vehicle suspension according to an embodiment of the present invention.

[0052] like Figure 2 As shown, in the air supply device provided by the utility model, in particular, the valve core 203 and the coil 202 of each solenoid valve 200 are centrally assembled in the integrated gas circuit module, and the solenoid valve 200 can be electrically connected to the controller outside the integrated gas circuit module through the pin 201 arranged at its end.

[0053] It should be noted that Figure 2 The thick line frame is used to represent the component structure of the solenoid valve 200, which aims to clearly show the internal structure of the integrated air circuit module in the vehicle suspension air supply device provided by the utility model. Compared with the solution of separately assembling the coil of the solenoid valve to the controller in the prior art, the structure of the solenoid valve core and the coil are assembled together in the utility model, which is easier to assemble, thereby meeting higher process and assembly accuracy requirements and saving costs.

[0054] In a more preferred embodiment, the integrated air circuit module in the air supply device of the vehicle suspension provided by the utility model is made of metal material, such as alloy materials such as aluminum and steel.

[0055] Compared with some solutions in the prior art that separate the coil of the solenoid valve in the controller, the suspension air supply device provided by the utility model centrally assembles the coil and the valve body of the solenoid valve inside the integrated air circuit module. At the same time, the integrated air circuit module is made of metal material, which can better play a role in heat dissipation.

[0056] It is easy to understand that during the continuous operation of the solenoid valve, the coil will inevitably generate heat. If the coil of the solenoid valve is separated from the valve body and arranged in the controller, the heat generated by the coil will have a superimposed effect on the heat generated by the operation of the hardware unit inside the controller. The controller shell is often made of plastic, which is not conducive to the dissipation of heat, causing hidden dangers of functional failure. The integrated gas circuit module 101 is also equipped with a compressor, which can be continued for reference. Figure 1 The motor 103 is connected to the compressor to drive the compressor to work, and the dryer 104 is used to dry the medium gas. The controller 102 is installed on an outer side of the integrated gas circuit module 101 to control the motor 103 and multiple solenoid valves. The integrated gas circuit module 101 is also used as an integrated valve body, integrating multiple solenoid valves with different functions together, so as to control the direction of the medium gas in each gas circuit and the on-off of the gas circuit.

[0057] In a preferred embodiment, the integrated gas circuit module 101 provided by the present invention is also provided with a plurality of medium gas transmission interfaces and a gas channel one-way valve for controlling the on-off of the medium gas transmission interface. Figure 1 In the illustrated embodiment, the top of the integrated gas circuit module 101 is provided with four yellow interfaces, namely, medium gas transmission interfaces 105, and the green valve is the airway check valve 106. The airway check valve 106 controls the on-off of the medium gas transmission interface 105, thereby sucking in the medium gas from the external environment, and then delivering it to the suspension system of the vehicle through the compression and drying process of the integrated gas circuit module 101, or releasing the useless medium gas into the atmosphere.

[0058] It should be particularly noted that in this embodiment, the arrangement position and manner of the medium gas transmission interface 105 and the airway one-way valve 106 are only illustrative and are not intended to limit the protection scope of the present utility model.

[0059] Figure 3 The present invention is a schematic diagram of the structure of an integrated air path module in an air supply device for a vehicle suspension from a bottom perspective according to an embodiment of the present invention.

[0060] Can be combined with reference Figure 3 In a preferred embodiment, the multiple solenoid valves with different functions provided by the utility model may include: multiple air circuit distribution valves, multiple air spring air supply valves and a reverse drying valve, the reverse drying valve is configured to switch the working mode of the dryer, and the working mode of the dryer includes drying the air supply gas output by the air supply device and reverse blowing the dryer.

[0061] It is easy to understand that the functions of the solenoid valves are only exemplarily described here, and are not used to limit the protection scope of the utility model. In fact, the solenoid valves here can also be air valves, control valves, switch valves, flow valves, regulating valves, pressure relief valves, etc. according to the specific functions integrated. The multiple solenoid valves can be controlled individually, and can be electrically connected and combined through the controller to cooperate with each other to realize the activation of different airways and the medium gas on and off of different inlets and outlets, thereby realizing the corresponding suspension control function.

[0062] In addition, it should be noted that the above embodiment is only an illustrative description of the assembly direction of the solenoid valve. In this embodiment, the axis of the solenoid valve is arranged perpendicular to the controller panel. In fact, the arrangement direction of the solenoid valve can be arbitrary, and the axis of the solenoid valve can be made perpendicular to the circuit board or at any angle to the circuit board for arrangement and assembly.

[0063] Further, in a preferred embodiment, reference may be made to Figure 3 The integrated gas circuit module provided by the utility model comprises two layers, wherein the first layer is provided with a plurality of interconnected air passages, and the second layer is open to accommodate the plurality of solenoid valves with different functions, and the solenoid valves are assembled and connected to the connection surface between the second layer and the first layer to control the direction of the medium gas. Figure 3 .

[0064] Figure 3 The figure shows a schematic diagram of the bottom view of the air supply device, excluding the controller part connected to the integrated air circuit module 301. The integrated air circuit module 301 is divided into two layers in the axial direction, and the motor 302 is assembled and connected to the integrated air circuit module 301. Figure 3 The bottom of the integrated gas circuit module 301, a layer in the integrated gas circuit module 301 close to the motor 302 is the first layer, and a plurality of interconnected air passages are provided inside, such as Figure 3 Shown by the blue line.

[0065] More preferably, in one embodiment, a compressor is further provided in the first layer of the integrated gas circuit module, and the motor 302 is mounted on the integrated gas circuit module 301 close to the outer side of the compressor, and the compressor is connected to the motor to pressurize the medium gas.

[0066] It is easy to understand that Figure 3 In the illustrated embodiment, although the specific structure of the compressor is not shown, it is included in the first bottom layer inside the integrated gas circuit module 301 connected to the motor 302. The compressor and the motor 302 are adjacently connected, so that the two can cooperate to compress the medium gas, and at the same time, the overall structure is more compact, saving assembly space and facilitating assembly.

[0067] You can continue to refer to Figure 3 , Figure 3 The upper layer of the integrated gas path module 301 is the second layer, that is, the open layer shown in the figure. Figure 3 As shown, the open second layer contains a plurality of solenoid valves 303 with shells of different colors. The difference in the color of the valve body shell indicates that they play different functional roles in the suspension system. The air supply device provided by the utility model centrally assembles the plurality of valve bodies with different functions in the integrated air circuit module 301, which can avoid assembly errors, improve process accuracy, and thereby ensure the functional stability of the suspension air supply device.

[0068] In the air supply device of the vehicle suspension provided by the utility model, a pin is provided at the end of the solenoid valve, and a plurality of contacts are directly provided on the controller. The pin of the solenoid valve is correspondingly connected to the corresponding contacts of the controller to realize the assembly connection of the plurality of solenoid valves and the controller.

[0069] Please continue to refer to Figure 1 , and can be combined Figure 3 In a preferred embodiment, in the air supply device of the vehicle suspension system provided by the utility model, the controller 102 can be in the shape of a plate, assembled and covered on the open surface of the second layer, and the integrated air circuit module also directly constitutes the shell of the controller. In some embodiments, it can also be used to install other controller components such as connectors, circuit boards, and upper covers.

[0070] The panel of the controller 102 is directly arranged with a plurality of contacts to correspond to the solenoid valves with different functions. The pins of each solenoid valve are directly inserted into the corresponding contacts to achieve electrical connection with the controller. For the specific structure, please refer to Figure 4 . Figure 4 The present invention is a schematic diagram of the structure of a device for assembling a solenoid valve pin and a controller contact in an air supply device for a vehicle suspension according to an embodiment of the present invention.

[0071] like Figure 4 As shown, the end of the solenoid valve 401 is provided with a pin 404, which can be a PIN pin made of metal ceramic material, for example. The controller circuit board 403 is provided with a contact 402 at a corresponding position, and the pin 404 of the solenoid valve 401 is inserted into the corresponding contact 402, thereby realizing the assembly and electrical connection between the solenoid valve and the controller.

[0072] The air supply device for the vehicle suspension provided by the utility model integrally assembles a plurality of solenoid valves with different functions into an integrated air circuit module with a regular appearance, thereby achieving a higher degree of integration and obtaining better process accuracy, avoiding assembly errors caused by the dispersed arrangement of components, making assembly work more convenient, and reducing the cost of materials and accessories.

[0073] The utility model also provides a suspension system for a vehicle, comprising an air supply device for the vehicle suspension as described in any one of the above items.

[0074] Another aspect of the present invention provides a vehicle, which comprises an air supply device for a vehicle suspension as described in any one of the above items.
