[0022] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the utility model will become clearer. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be directly connected or connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In the description of the present invention, the meaning of "multiple" is at least two, such as two or three or more, etc.

[0025] The present invention is described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the absence of conflict, the following embodiments and features in the embodiments may complement or be combined with each other.

[0026] like Figure 1 As shown, a preferred embodiment of the utility model provides an air supply device, which is applied to an electronically controlled suspension system, and includes a compressor 1, a heat dissipation mechanism 2, an air circuit module 3, and a dryer 4. The compressor 1 and the dryer 4 are both connected to the air circuit module 3, and the working medium output by the compressor 1 is transported to the dryer 4 through the air circuit module 3. The heat dissipation mechanism 2 is connected to at least one of the compressor 1, the air circuit module 3, and the dryer 4.

[0027] The compressor 1 is used to pressurize the working medium, the heat dissipation mechanism 2 is used to dissipate the heat of the pressurized working medium and the working medium before entering the dryer 4, the gas path module 3 is used to transport the working medium after the heat is dissipated to the dryer 4, and the dryer 4 is used to dry the pressurized working medium. It should be understood that the above-mentioned working medium refers to the gas that needs to be pressurized by the compressor 1, such as air or other types of gas.

[0028] When the air supply device is working, the compressor 1 first delivers the output high-temperature and high-pressure gas to the heat dissipation mechanism 2 for heat dissipation. After the heat is dissipated, the high-pressure gas is input into the dryer 4 through the gas path module 3 for drying.

[0029] The air supply device provided in the present application is provided with a heat dissipation mechanism 2, which can dissipate the heat of the working medium before the working medium enters the dryer 4 to reduce the temperature of the working medium, so that the water vapor in the high-temperature and high-pressure gas output by the compressor 1 enters the dryer 4 after preliminary condensation, which can reduce the workload of the dryer 4, reduce the number of regenerations of the dryer 4, and thus increase the service life of the dryer 4. In addition, the air supply device can also improve the dryness of the gas output by the dryer 4, reduce gas loss, and thus improve the quality of the gas output by the air supply device.

[0030] Furthermore, the gas path module 3 has at least one gas passage (not shown), one end of which is connected to the compressor 1 , and the other end is connected to the dryer 4 , so that the high-temperature and high-pressure gas output by the compressor 1 enters the dryer 4 through the gas passage.

[0031] In addition, the gas circuit module 3 also includes at least one solenoid valve (not shown), so the gas circuit module 3 is also used as a valve body. The solenoid valve is used to drive the opening and closing of a corresponding airway, that is, each airway is connected or cut off by a corresponding solenoid valve to realize the opening and closing of each airway.

[0032] The present application does not limit the type of solenoid valve. The solenoid valve can be an air valve, a control valve, a switch valve, a flow valve, a regulating valve, a pressure relief valve, a drain valve, etc. according to the specific function of the gas circuit module 3.

[0033] Continue to refer to Figure 1 In a preferred embodiment, the heat dissipation mechanism 2 is arranged on the compressor 1 to dissipate the heat of the working medium output by the compressor 1. With such a structure, on the one hand, the action area between the heat dissipation mechanism 2 and the gas can be increased, thereby improving the heat dissipation effect of the gas; on the other hand, the overall size of the gas supply device can be reduced, making the gas supply device more compact, thereby facilitating the use of the gas supply device.

[0034] In another preferred embodiment, the heat dissipation mechanism 2 may also be disposed on the gas path module 3. For example, the heat dissipation mechanism 2 may be wrapped around each gas passage in the gas path module 3 to dissipate heat for the gas flowing through the gas passage.

[0035] In another preferred embodiment, the heat dissipation mechanism 2 may also be provided between the compressor 1 and the gas circuit module 3. In a specific example, the heat dissipation mechanism 2 may include a heat sink and a pipeline (not shown) connected to each other, and the two ends of the pipeline are respectively connected to the compressor 1 and the gas circuit module 3, and the heat sink is used to dissipate heat for the working medium flowing through the pipeline. With such a structure, the high-pressure gas output by the compressor 1 can enter the gas circuit module 3 through the pipeline of the heat dissipation mechanism 2, and the high-pressure gas can dissipate heat when flowing through the pipeline of the heat dissipation mechanism 2.

[0036] In another preferred embodiment, the heat dissipation mechanism 2 may also be arranged between the gas circuit module 3 and the dryer 4. For example, the two ends of the pipeline of the heat dissipation mechanism 2 may be respectively connected to the gas circuit module 3 and the dryer 4, so that the heat dissipation mechanism 2 can reduce the temperature of the high-pressure gas before the high-pressure gas enters the dryer 4.

[0037] Only some embodiments of the heat dissipation mechanism 2 are listed above. The present application does not limit the location of the heat dissipation mechanism 2 . The location of the heat dissipation mechanism 2 only needs to be able to dissipate the working medium before entering the dryer 4 .

[0038] Continue to refer to Figure 1 The air supply device preferably further includes a drainage mechanism 5, which is arranged on at least one of the compressor 1, the gas path module 2 and the dryer 4. The drainage mechanism 5 can be arranged between the heat dissipation mechanism 2 and the dryer 4. The drainage mechanism 5 is used to discharge the liquid condensed after the working medium dissipates heat (that is, the working medium dissipates heat after passing through the heat dissipation mechanism 2), that is, the liquid condensed after part of the high-temperature and high-pressure gas output by the compressor 1 dissipates heat is discharged by the drainage mechanism 5 (for example, water vapor formed after the air is condensed after passing through the heat dissipation mechanism 2). Such a configuration can not only prevent the liquid from obstructing the flow of gas in the airway, but also prevent the liquid from mistakenly entering the dryer 4 and increasing the workload of the dryer 4.

[0039] In a specific solution, the drainage mechanism 5 can be arranged on the air path module 3 and connected to the airway to facilitate the installation of the drainage mechanism 5 and the discharge of liquid.

[0040] In another specific solution, when the heat dissipation mechanism 2 is installed on the compressor 1 , the exhaust mechanism 5 can be installed on the compressor 1 or the dryer 4 , and the specific installation position of the drainage mechanism 5 only needs to be sufficient to discharge the liquid in the air duct before the gas enters the dryer 4 .

[0041] Reference Figure 1As shown, in a specific example, the drainage mechanism 5 is configured as a drainage valve, and the drainage valve can be installed on the compressor 1, the gas circuit module 3 or the dryer 4, preferably on the gas circuit module 3, to facilitate drainage and make the structure compact.

[0042] In another specific example, the drainage mechanism 5 can also be configured as a pump or other water absorbing device to extract or absorb the condensed liquid in the airway. The present application does not limit the structure and type of the drainage mechanism 5.

[0043] Furthermore, the air supply device also includes a circuit board 6 (refer to Figure 1 ), the circuit board 6 is electrically connected to the gas circuit module 3, specifically to the solenoid valve in the gas circuit module 2, so that even if the position of the solenoid valve changes, it is not easy to interfere with the circuit board 6, thereby ensuring the stability of the use of the gas supply device. The circuit board 6 is used to change the working state of the solenoid valve. Specifically, the circuit board 6 is used to control the on-off of the solenoid valve to further control the on-off of each gas channel in the gas supply device.

[0044] In addition, the air supply device further includes a motor 7, which is connected to the compressor 1 and the circuit board 6 respectively, and is used to drive the compressor 1 to pressurize the working medium under the drive of the circuit board 6. Specifically, the output transmission member of the motor 7 is connected to the input transmission member of the compressor 1 to realize the driving of the compressor 1 by the motor 7.

[0045] Since the present application does not involve improvements to the compressor 1, the dryer 4, the circuit board 6 and the motor 7, those skilled in the art can understand their structures based on the prior art and will not be described in detail.

[0046] In a preferred embodiment, the motor 7 is installed on the side of the compressor 1 away from the gas circuit module 3, and the circuit board 6 and the compressor 1 are respectively arranged on opposite sides of the gas circuit module 3. The dryer 4 is arranged on a side of the gas circuit module 3 adjacent to the compressor 1. In this way, the compressor 1, the dryer 4 and the circuit board 6 can be arranged adjacent to the gas circuit module 3 to facilitate the flow of high-pressure gas and the driving of the solenoid valve and the motor 7 by the circuit board 6.

[0047] like Figure 1 As shown, in this embodiment, the circuit board 6 is installed on the upper surface of the gas circuit module 3, the compressor 1 is installed on the lower surface of the gas circuit module 3, and the dryer 4 is installed on a side surface of the gas circuit module 3 to simplify the structure of the gas supply device.

[0048] It should be understood that the upper surface of the air circuit module 3 refers to the surface of the air circuit module 3 close to the motor 7, the lower surface of the air circuit module 7 refers to the surface arranged opposite to the upper surface of the air circuit module 3, and the side surface of the air circuit module 3 refers to the surface connected to both the upper and lower surfaces of the air circuit module 3.

[0049] It should also be understood that the angles between the upper surface and the side surface, and the side surface and the lower surface of the gas path module 3 can be set arbitrarily, for example, can be set to close to 90°. This application does not limit the angle between the upper surface and the side surface, and the angle between the side surface and the lower surface.

[0050] In a preferred embodiment, the gas circuit module 3 includes a first housing (not numbered), and the gas channel, the solenoid valve and the circuit board 6 are all arranged in the first housing of the gas circuit module 3. Such a configuration can make the solenoid valve and the circuit board 6 more stable, and the gas supply device is integrated into a whole, and at the same time make the installation position of the solenoid valve more reasonable, so as to simplify the assembly process of the gas supply device.

[0051] In another preferred embodiment, the air supply device has a second shell and a third shell connected to each other, the motor 7 is arranged on one side of the second shell, and the third shell is arranged on a side of the second shell away from the motor 7. During actual assembly, the airway and the solenoid valve can be placed in the second shell of the air path module 3, and the circuit board 6 can be placed in the third shell to achieve the connection between the circuit board and the solenoid valve.

[0052] Reference Figure 2 As shown, in a non-limiting embodiment, the working principle of the gas supply device includes the following steps:

[0053] 1) The circuit board 6 drives the motor 7 to operate, and after the motor 7 operates, it drives the compressor 1 to pressurize the low-pressure humid gas 10 input inside;

[0054] 2) The high-temperature and high-pressure humid gas output by the compressor 1 flows through the heat dissipation mechanism 2, and the high-temperature and high-pressure humid gas is cooled down and partially condensed into liquid under the action of the heat dissipation mechanism 2;

[0055] 3) The condensed liquid is discharged from the air supply device through the drainage mechanism 5;

[0056] 4) The high-pressure humid gas after heat dissipation enters the dryer 4 through the air passage of the air path module 3;

[0057] 5) The high-pressure wet gas is transformed into high-pressure dry gas 20 under drying in the dryer 4 and flows back into the gas path module 3;

[0058] 6) The circuit board 6 controls the on / off of the electromagnetic valve in the gas circuit module 3 so as to deliver the high-pressure dry gas 20 in the gas circuit module 3 to the external device when the electromagnetic valve is opened.

[0059] In summary, the air supply device provided by the present application is provided with a heat dissipation mechanism 2, which can dissipate heat from the working medium before the working medium enters the dryer 4 to reduce the temperature of the working medium, so that the water vapor in the high-temperature and high-pressure gas output by the compressor 1 enters the dryer 4 after preliminary condensation, thereby reducing the workload of the dryer 4, reducing the number of regenerations of the dryer, and thus increasing the service life of the dryer. In addition, the air supply device can also improve the dryness of the gas output by the dryer, reduce gas loss, and thus improve the quality of the gas output by the air supply device.
