Description

Technical Field

[0001] The utility model relates to the technical field of air suspension, in particular to an air supply unit, an air spring and a vehicle. Background Art

[0002] Air springs are widely used because they provide shock absorption and cushioning for vehicles, adapting to road conditions in real time. Existing air springs are equipped with an air supply unit, which supplies and withdraws air to adjust the spring's stiffness. However, since air contains moisture, if this moisture enters the air spring, it will accumulate there, shortening its service life. Therefore, current air supply units are equipped with a dryer to dry the air.

[0003] However, after the dryer absorbs a certain amount of moisture, the internal desiccant needs to be dried and regenerated. At present, the regeneration of the dryer is mostly carried out by using the heat generated by the compressor. However, due to the short working time of the compressor during actual use of the vehicle, in most cases the compressor stops working before the drying temperature required by the dryer is reached, resulting in the dryer being unable to achieve the expected regeneration effect and affecting the drying capacity.

[0004] Therefore, there is an urgent need to provide an air supply unit, an air spring and a vehicle to solve the problems existing in the prior art to a certain extent. Utility Model Content

[0005] The purpose of the utility model is to provide an air supply unit to optimize the structure of the air supply unit to a certain extent, improve the drying and regeneration effect of the desiccant, and ensure the air drying quality.

[0006] The utility model provides an air supply unit, comprising a main body, a drying component and a heating component; an air duct is formed in the main body, the drying component is arranged in the air duct, the heating component comprises a heating component and a heat-conducting component, the heat-conducting component is arranged to cover the drying component; the heating component is in contact with the heat-conducting component.

[0007] Wherein, the heating component is a resistance wire, and the resistance wire is wound around the outside of the heat-conducting component.

[0008] Specifically, the heating component is a PTC thermistor, and the heating block is fixedly connected to the outside of the heat-conducting component.

[0009] Furthermore, the drying component includes a desiccant and a drying cylinder, the desiccant is contained in the drying cylinder, the heat-conducting component is covered on the outside of the drying cylinder, an air inlet and an air outlet are formed at both ends of the drying cylinder, and avoidance portions are formed at both ends of the heat-conducting component corresponding to the positions of the air inlet and the air outlet.

[0010] Among them, the main mechanism includes a pneumatic block, a motor, a compressor and a control component; the motor is connected to the compressor to drive the compressor to provide high-pressure air into the airway, and the control component is connected to the airway to control the opening and closing of the airway.

[0011] Specifically, a plurality of air passages are formed in the pneumatic block, and the control component includes a plurality of valve bodies, and the plurality of valve bodies are connected to the air passages correspondingly.

[0012] Furthermore, the control assembly further includes a control board, which is connected to a plurality of the valve body circuits to control the on and off of the valve bodies.

[0013] Furthermore, a first bearing portion is formed on the pneumatic block, and the plurality of valve bodies are all arranged on the first bearing portion.

[0014] Compared with the prior art, the air supply unit provided by the present invention has the following advantages:

[0015] The air supply unit provided by the utility model includes a main body structure, a drying component and a heating component; an air duct is formed in the main body structure, the drying component is arranged in the air duct, the heating component includes a heating component and a heat-conducting component, and the heat-conducting component is arranged to cover the drying component; the heating component is in contact with the heat-conducting component.

[0016] From this analysis, it can be seen that by arranging a drying component in the air passage of the main body, the passing air can be dried and most of the moisture in the air can be filtered, thereby ensuring the dryness of the air entering the air spring. Accordingly, by arranging a heating component outside the drying component, and the heating component in this application includes a heating member and a heat-conducting member, the heat-conducting member can cover the drying component and fit with the outer wall surface of the drying component, and by arranging the heating component outside the heat-conducting member, the heating member can heat the heat-conducting member, thereby evenly transferring heat to the drying component, thereby achieving dry regeneration of the drying component.

[0017] It is understandable that when the drying component needs to be dried and regenerated, the heating component is energized to generate heat, and the heat is transferred to the outer wall of the drying component by the heat-conducting component, and the drying component is continuously heated, thereby achieving dry regeneration of the drying component.

[0018] Since the present application uses an independent heating component to dry the drying component, it can stably provide heat, so that the drying noise can be stably maintained at a predetermined temperature during the drying process, ensuring the drying and regeneration effect of the drying component. At the same time, since the drying component in the present application is coated with a heat-conducting component, the heat can be further evenly transferred to the drying component through the heat-conducting component, thereby improving the regeneration effect.

[0019] It should be noted that the power source of the heating component in the present application can be the battery in the vehicle, that is, the battery is directly connected to the heating component using a lead, so as to provide stable power for the heating component.

[0020] In addition, the utility model also provides an air spring, comprising the above-mentioned air supply unit.

[0021] The air spring using the air supply unit provided in this application can regenerate the internal drying component after a certain period of use, thereby ensuring the drying effect, preventing a large amount of moisture from entering the air spring through the air, affecting the operation of the air spring, and ensuring the service life of the air spring.

[0022] The utility model also provides a vehicle, comprising a power source and the above-mentioned air spring, wherein the power source is connected to a circuit of the heating component.

[0023] This application directly uses the power supply in the vehicle to provide power for the heating component, can control the heating time according to specific needs, and will not be interfered with by other structures, thereby providing stable heat to achieve drying and regeneration of the above-mentioned drying components, ensuring the service life of the air spring, thereby reducing the frequency of vehicle maintenance and improving user experience.

[0037] like Figure 1 As shown, the utility model provides an air supply unit, including a main body structure, a drying component 2 and a heating component; an air duct is formed in the main body structure, the drying component 2 is arranged in the air duct, the heating component includes a heating component 3 and a heat-conducting component 4, the heat-conducting component 4 is arranged to cover the drying component 2, and the heat-conducting component 4 is in contact with the outer wall surface of the drying component 2; the heating component 3 is arranged outside the heat-conducting component 4 and is in contact with the outer wall surface of the heat-conducting component 4.

[0038] Compared with the prior art, the air supply unit provided by the present invention has the following advantages:

[0039] The air supply unit provided by the present invention, by disposing a drying assembly 2 within the air passage of the main body, can dry the air passing through it and filter out most of the moisture in the air, thereby ensuring the dryness of the air entering the air spring. Accordingly, by disposing a heating assembly outside the drying assembly 2, the heating assembly in this application includes a heating component 3 and a heat-conducting component 4. The heat-conducting component 4 can cover the drying assembly 2 and conform to the outer wall surface of the drying assembly 2. By disposing the heating component 3 outside the heat-conducting component 4, the heating component 3 can heat the heat-conducting component 4, thereby evenly transferring heat to the drying assembly 2, thereby achieving dry regeneration of the drying assembly 2.

[0040] It is understandable that when the drying component 2 needs to be dried and regenerated, the heating component 3 is energized to generate heat, and the heat is transferred to the outer wall of the drying component 2 by the heat-conducting component 4, and the drying component 2 is continuously heated, thereby achieving dry regeneration of the drying component 2.

[0041] Since the present application uses an independent heating component 3 to dry the drying component 2, it can stably provide heat, so that the predetermined temperature can be stably maintained during the drying process, ensuring the drying and regeneration effect of the drying component 2. At the same time, since the drying component 2 in the present application is coated with a heat-conducting component 4, the heat can be further evenly transferred to the drying component 2 through the heat-conducting component 4, thereby improving the regeneration effect.

[0042] It should be noted that the power source 8 of the heating component 3 in the present application can be a battery in the vehicle, that is, the battery is directly connected to the heating component 3 using a lead, so as to provide stable power for the heating component 3.

[0043] Based on the above structure, the present application provides two embodiments of the heating component 3, wherein one heating component 3 is a resistance wire, which is wound around the outside of the heat-conducting component 4 and connected to the power supply 8 line.

[0044] By winding the resistance wire around the outside of the heat-conducting component 4 , the resistance wire can generate heat when power is supplied, so that the heat is evenly conducted to the drying component 2 through the heat-conducting component 4 , thereby achieving drying and regeneration of the drying component 2 .

[0045] It is understandable that since the drying component 2 is not actually a regular structure, if the resistance wire is directly wound on the drying component 2, gaps will inevitably appear. The present application further arranges a heat-conducting component 4. Even if a gap occurs between the resistance wire and the heat-conducting component 4, the area where the gap exists can be filled to a certain extent, making the heat transfer more uniform and improving the regeneration effect.

[0046] Correspondingly, another embodiment of the heating component 3 provided in the present application is a heating block, which is fixedly connected to the outside of the heat-conducting component 4 and connected to the power supply 8 line.

[0047] In this manner, the heating block may be a block-shaped, plate-shaped or strip-shaped structure. When powered on, the heating block generates heat, thereby enabling the heat to be transferred to the drying assembly 2 through the heat-conducting member 4 .

[0048] It is understandable that in this embodiment, the heat generated by the heating block is more concentrated, so the heat can be quickly transferred to the entire contact surface between the drying component 2 and the heat conducting component 4 through the heat conducting component 4, thereby ensuring the drying regeneration effect.

[0049] It should be noted here that the heating block and the heat-conducting component 4 in the present application can be fixedly connected by welding to avoid the heating block from separating during use, resulting in the inability to heat the drying component 2 or even causing damage to the air supply unit.

[0050] Preferably, the heat-conducting component 4 in the present application is made of aluminum or aluminum alloy material, that is, it has good thermal conductivity and a certain strength, thereby playing a role in protecting the drying component 2 to a certain extent.

[0051] Optionally, the drying component 2 in the present application includes a desiccant and a drying cylinder, the desiccant is contained in the drying cylinder, the heat-conducting component 4 is covered on the outside of the drying cylinder, and an air inlet and an air outlet are formed at both ends of the drying cylinder, and avoidance portions are formed at the positions of the air inlet and the air outlet at both ends of the heat-conducting component 4.

[0052] The drying cylinder allows for stable loading of the desiccant, while the air inlet and outlet formed at both ends of the drying cylinder allow for the flow of gas. Accordingly, the heat-conducting member 4 in this application is provided with relief portions at both ends, thereby avoiding obstruction of the airflow to a certain extent and ensuring the normal drying function of the drying assembly 2.

[0053] Alternatively, as Figure 1 As shown, the main mechanism in this application includes a pneumatic block 1, a motor 5, a compressor 6 and a control component 7; the motor 5, the compressor 6 and the control component 7 are all arranged on the pneumatic block 1, and the motor 5 is connected to the compressor 6 to drive the compressor 6 to provide high-pressure air into the airway, and the control component 7 is connected to the airway to control the opening and closing of the airway.

[0054] The pneumatic block 1 can provide a stable installation position for the motor 5 , the compressor 6 and the control component 7 . In fact, the air duct mentioned above in this application is formed in the pneumatic block 1 , and accordingly, the drying component 2 is arranged in the pneumatic block 1 .

[0055] It can be understood that since the air spring needs to realize the process of inflation and deflation, multiple air channels need to be formed in the pneumatic block 1. Accordingly, the control component 7 includes multiple valve bodies, and the multiple valve bodies are connected to the air channels accordingly, so that the connection and closure of different air channels can be achieved through the corresponding valve bodies, thereby realizing the inflation and deflation process of the air spring.

[0056] Optionally, the control component 7 in the present application further includes a control board, which is connected to a plurality of valve body circuits to control the on and off of the valve bodies.

[0057] The control board in the present application may be a PCB board, which is used to realize on-off control of multiple valve bodies, thereby realizing on-off of the air passage, and further realizing the inflation and deflation of the air spring.

[0058] Preferably, if Figure 1 As shown, a first bearing part is formed on the pneumatic block 1 in the present application, and multiple valve bodies are arranged on the first bearing part. The formed first bearing part can provide an installation basis for multiple valve bodies, avoiding the problem of interference between the valve bodies and other structures.

[0059] In addition, the utility model also provides an air spring, comprising the above-mentioned air supply unit.

[0060] The air spring using the air supply unit provided in this application can regenerate the internal drying component 2 after a certain period of use, thereby ensuring the drying effect, preventing a large amount of moisture from entering the air spring through the air, affecting the operation of the air spring, and ensuring the service life of the air spring.

[0061] The present invention further provides a vehicle, comprising a power source 8 and the above-mentioned air spring, wherein the power source 8 is connected to the heating component 3 by a circuit.

[0062] The present application directly uses the in-vehicle power supply 8 to provide power to the heating component 3, which can control the heating time according to specific needs without being interfered with by other structures, thereby providing stable heat to achieve the drying and regeneration of the above-mentioned drying component 2, ensuring the service life of the air spring, thereby reducing the frequency of vehicle maintenance and improving the user experience.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
