Description

Technical Field

[0001] This utility model relates to the field of air supply technology, and in particular to an electronically controlled controller suspension air supply unit device. Background Technology

[0002] In the automotive field, air suspension systems are widely used due to their ability to provide excellent comfort and adaptability. Air suspension delivers air to the suspension system through an air supply unit to achieve height adjustment and shock absorption. The core component of the air supply unit is an air compressor, whose intake end is connected to an intake pipe. An air filter is installed along the intake pipe path to filter dust and impurities from the air entering the air compressor. The air compressor's outlet end is connected to a solenoid valve through a high-pressure pipe. The solenoid valve then delivers compressed air to the air suspension system through a conduit. During operation, the air compressor draws in outside air through the intake pipe. After being filtered by the air filter, the air is compressed and delivered through the high-pressure pipe to the solenoid valve, ultimately reaching the air suspension to achieve the normal operation of the suspension system.

[0003] However, the air supply unit is installed on a car to deliver air to the air suspension. Since the car inevitably experiences bumps during driving, this causes relative movement between the internal components of the unit. In particular, the connection between the intake pipe and the air filter is prone to loosening under long-term bumps. Existing devices lack an effective protective structure to prevent gas leakage after the connection between the intake pipe and the air filter becomes loose. This not only reduces the performance of the air suspension system but may also pose a potential threat to the safety and reliability of the vehicle.

[0004] To address the aforementioned issues, this application proposes an electronically controlled suspension air supply unit device. Utility Model Content

[0005] Based on the technical problems existing in the background art, this utility model proposes an electronically controlled suspension air supply unit device.

[0006] The present invention proposes an electronically controlled controller suspension air supply unit device, which includes an air compressor, an intake main pipe, an intake secondary pipe, an air filter, and a filter air guide assembly;

[0007] The air filter is connected between the main intake pipe and the secondary intake pipe. The end of the main intake pipe away from the air filter is connected to the intake end of the air compressor. The outlet end of the air compressor is connected to an electronically controlled exhaust device.

[0008] Both ends of the air filter are equipped with leak-proof covers. The two leak-proof covers are respectively fitted onto the end of the main intake pipe and the secondary intake pipe near the air filter. The air filter assembly is connected to the two leak-proof covers and the main intake pipe.

[0009] A flow sensor is installed in the path of the intake manifold;

[0010] When a leak occurs at the connection between the main intake pipe, the secondary intake pipe, and the air filter, the air drawn by the air compressor can enter the filter guide assembly for filtration, and then enter the air compressor through the main intake pipe.

[0011] Preferably, the air filtration assembly includes a manifold, a filter cartridge, and an air guide. The manifold is connected to two branch pipes, which are respectively connected to two leak-proof covers. A filter cartridge for filtering gas is connected to the outside of the manifold. The end of the filter cartridge away from the manifold is detachably connected to an air guide that is connected to the main air intake pipe.

[0012] Preferably, a gas sensor is installed at one end of the manifold.

[0013] Preferably, the filter cartridge includes an air passage cylinder and a filter element, the outside of the manifold is connected to the air passage cylinder, the filter element is disposed inside the air passage cylinder, and the air guide is detachably connected to the air passage cylinder.

[0014] Preferably, the air guide includes a conduit, one end of which is connected to a connector and the connector is threaded to the end of the air cylinder away from the manifold, the other end of which is connected to the main air intake pipe, and a valve is installed on the conduit.

[0015] Preferably, the electronically controlled exhaust component includes a solenoid valve, a high-pressure pipe, and an exhaust connector. The exhaust end of the air compressor is connected to the solenoid valve via the high-pressure pipe, and the exhaust end of the solenoid valve is connected to the exhaust connector.

[0016] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0017] 1. The flow sensor monitors the gas flow rate in real time. When a leak occurs at the connection between the main intake pipe or the intake auxiliary pipe and the air filter, the flow rate change can be detected quickly and the staff can be alerted to check and repair. The air filter can filter dust in the air, ensuring the quality of the air entering the air compressor and extending the service life of the equipment. The electronically controlled exhaust components can control the exhaust volume and ensure the stable operation of the air suspension device. The overall design effectively avoids the performance degradation of the air suspension system caused by gas leakage, ensures the normal operation of the vehicle, and improves the reliability and safety of the system.

[0018] 2. When a leak occurs at the connection, the flow sensor can detect the change in gas flow in a timely manner. At this time, the valve of the air guide component in the filter air guide assembly is opened, and the leaking air can enter the branch pipe of the filter air guide assembly through the leak-proof cover. After passing through the manifold, filter cartridge, and air guide component, it re-enters the main intake pipe and finally enters the air compressor. The filter cartridge can filter the dust in the leaking air to ensure that the gas quality delivered by the air compressor to the air suspension system meets the standards. This structure can not only respond quickly in case of a leak and avoid affecting the operation of the entire device, but also provide sufficient maintenance time for the staff to prevent the system from shutting down due to the leak, thus greatly improving the safety and reliability of vehicle operation.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0026] like Figure 1-5As shown, the present invention proposes an electronically controlled controller suspension air supply unit device, which includes an air compressor 1, an intake main pipe 101, an intake secondary pipe 102, an air filter 2, and a filter air guide assembly 5.

[0027] Air filter 2 is connected between intake main pipe 101 and intake secondary pipe 102. The end of intake main pipe 101 away from air filter 2 is connected to the intake end of air compressor 1. The outlet end of air compressor 1 is connected to electronically controlled exhaust component 3.

[0028] Both ends of the air filter 2 are equipped with leak-proof covers 4. The two leak-proof covers 4 are respectively fitted onto the end of the main intake pipe 101 and the secondary intake pipe 102 near the air filter 2. The filter air guide assembly 5 is connected to the two leak-proof covers 4 and the main intake pipe 101 respectively.

[0029] A flow sensor 1011 is installed in the path of the intake manifold 101;

[0030] When a leak occurs at the connection between the main intake pipe 101, the secondary intake pipe 102 and the air filter 2, the air drawn by the air compressor 1 can enter the filter guide assembly 5 for filtration, and then enter the air compressor 1 through the main intake pipe 101.

[0031] When the device is operating normally, the air compressor 1 starts and generates negative pressure. External air first enters the air filter 2 through the intake manifold 102. The air filter 2 intercepts dust, particulate matter, and other impurities in the air, achieving preliminary filtration. The purified air is then delivered to the air compressor 1 through the main intake manifold 101 for compression. The flow sensor 1011 on the main intake manifold 101 monitors the gas flow in the pipe in real time, forming a stable flow monitoring benchmark. When vehicle movement causes the connection between the main intake manifold 101 or the intake manifold 102 and the air filter 2 to loosen and leak, the airflow state inside the pipe is disrupted, and the flow sensor 1011 will quickly... The system quickly detects abnormal changes in airflow and issues timely warning signals to remind staff to investigate leaks and prevent insufficient air supply to the air suspension system due to gas leaks. At the same time, the leak-proof covers 4 at both ends of the air filter 2 will cover the leak point and gather the leaked air to the filter guide assembly 5. After secondary filtration by the filter guide assembly 5, the air is reintroduced into the intake main pipe 101, ensuring that the air entering the air compressor 1 remains clean. This not only ensures the normal operation of the air compressor 1 but also prevents impurities from entering and causing component wear, effectively maintaining the performance stability of the air suspension system and improving the safety and reliability of vehicle driving.

[0032] In a specific embodiment, the air filtration assembly 5 includes a manifold 51, a filter cartridge 52, and an air guide 53. Two branch pipes 511 are connected to the manifold 51, and each branch pipe 511 is connected to one of two leak-proof covers 4. A filter cartridge 52 for filtering the gas is connected to the outside of the manifold 51. The end of the filter cartridge 52 away from the manifold 51 is detachably connected to the air guide 53, which is connected to the main air intake 101. When a leak occurs at the connection, the leaked air collected by the leak-proof covers 4 flows into the manifold 51 through the two branch pipes 511. The manifold 51 concentrates and integrates the two dispersed airflows, forming a stable airflow channel to ensure that the gas can flow smoothly to the filter cartridge 52. The filter structure inside the cylinder 52 filters impurities in the leaked air, removing dust, debris, and other contaminants, preventing unfiltered air from entering the air compressor 1 and causing wear or malfunction of internal parts. The filtered air is then transported to the intake manifold 101 through the air guide 53, and finally enters the air compressor 1 to complete compression and air supply. This multi-component collaborative structural design not only realizes the recovery and reuse of leaked gas and avoids gas waste, but also ensures gas quality through secondary filtration. At the same time, the detachable connection between the air guide 53 and the filter cylinder 52 facilitates the maintenance and replacement of the filter cylinder 52 in the future, improving the practicality and ease of maintenance of the device.

[0033] In a specific embodiment, a gas sensor 512 is installed at one end of the manifold 51 and extends into it. When leaked gas enters the manifold 51, the gas sensor 512 will detect key parameters such as impurity content and humidity in the gas in real time. If the gas purity is not up to standard, it will promptly send a signal to remind the staff to replace the filter cartridge 52 to ensure that the filtration effect of the air duct assembly 5 is always in the best state. At the same time, the gas sensor 512 can also help judge the severity of the leak. When the gas flow rate is detected to be continuously increasing or the impurity content is abnormally high, it can indirectly reflect the size and location of the leak point, providing data support for the staff to quickly locate the fault and shorten the maintenance time. In addition, the setting of this sensor can also form a dual monitoring mechanism, which works in conjunction with the flow sensor 1011 on the intake manifold 101 to further improve the accuracy and timeliness of leak detection.

[0034] In a specific embodiment, the filter cartridge 52 includes an air passage 521 and a filter element 522. The air passage 521 is connected to the outside of the manifold 51, and the filter element 522 is disposed inside the air passage 521. The air guide 53 is detachably connected to the air passage 521. When the leaked gas delivered by the manifold 51 enters the air passage 521, the airflow passes through the filter element 522. The filter material of the filter element 522 captures small particles, dust and other impurities in the air through physical interception and adsorption, thereby purifying the gas. At the same time, the detachable connection between the air guide 53 and the air passage 521 allows the staff to easily disassemble the air guide 53 and remove the filter element 522 for cleaning or replacement, avoiding the filter effect being affected by the clogging or aging of the filter element 522, extending the service life of the filter cartridge 52 and reducing maintenance costs.

[0035] In a specific embodiment, the air guide component 53 includes a conduit 531. One end of the conduit 531 is connected to a connector 532, and the connector 532 is threadedly connected to the end of the air cylinder 521 away from the manifold 51. The other end of the conduit 531 is connected to the main air intake 101. A valve 533 is installed on the conduit 531 and is connected to the vehicle control system. When the flow sensor 1011 detects a leak at the connection and issues a warning, the vehicle control system controls the valve 533 to open, thus opening the emergency channel formed by the filter air guide component 5. This allows the purified leaked gas to enter the main air intake 101 along the conduit 531. The valve 533 can also adjust the airflow according to the leakage situation. When the leakage is small, the valve 533 opening can be appropriately reduced to avoid excessive emergency airflow affecting the stability of the main air supply channel, ensuring the overall air supply balance of the device, and further improving the operational stability of the air suspension system.

[0036] In a specific embodiment, the electronically controlled exhaust component 3 includes a solenoid valve 31, a high-pressure pipe 32, and an exhaust connector 33. The exhaust end of the air compressor 1 is connected to the solenoid valve 31 through the high-pressure pipe 32, and the exhaust end of the solenoid valve 31 is connected to the exhaust connector 33.

[0037] The electronically controlled exhaust component 3 is the core of the compressed gas output control for the air compressor 1. Its high-pressure pipe 32 can withstand the high-pressure gas output from the air compressor 1, ensuring that the gas will not leak or rupture due to excessive pressure during transportation, thus guaranteeing the safety and stability of gas transportation. The high-pressure gas compressed by the air compressor 1 is transported to the solenoid valve 31 through the high-pressure pipe 32. The solenoid valve 31 is controlled by an electronic control signal, which can adjust the opening degree and on / off state of the valve 533 according to the pressure requirements of the air suspension system, thereby controlling the flow and pressure of the output gas. This allows the air suspension system to quickly respond to height adjustment and shock absorption requirements, improving the vehicle's comfort and handling. The exhaust connector 33 serves as the interface for connecting to the air suspension system. Its structural design ensures a tight connection with the connecting pipe, reducing gas leakage. It also facilitates the installation of the device with different types of air suspension systems, improving the device's versatility. In addition, the electronic control design of the solenoid valve 31 enables automated control of gas output, linking with the vehicle's control system. It adjusts the air supply parameters in real time according to the vehicle's driving status and road conditions, further optimizing the performance of the air suspension system and ensuring that the vehicle maintains a good driving condition in different driving scenarios.

[0038] In a specific embodiment, the device is mounted on a frame at the corresponding location on the vehicle.

[0039] The specific working principle of this device is as follows:

[0040] After the vehicle starts, the air compressor 1 starts to generate negative pressure. External air enters the air filter 2 through the intake manifold 102. The air filter 2 intercepts dust, particulate matter and other impurities in the air, completing the initial filtration. The purified air is delivered to the air compressor 1 through the intake manifold 101. The air compressor 1 compresses the air into high-pressure gas, which is then delivered to the solenoid valve 31 through the high-pressure pipe 32. The solenoid valve 31 adjusts the valve opening according to the pressure requirements of the air suspension system through the electronic control signal to control the flow and pressure of the high-pressure gas. Finally, it is delivered to the air suspension system through the outlet connector 33 and the connecting pipe to realize the height adjustment and shock absorption functions of the suspension. During this stage, the flow sensor 1011 on the intake manifold 101 monitors the gas flow in the pipe in real time, and the valve 533 in the filter air guide assembly 5 is in the closed state to avoid airflow interference.

[0041] When the vehicle experiences bumps during operation, causing the connection between the main intake pipe 101 or the secondary intake pipe 102 and the air filter 2 to become loose and leak, the airflow state in the main intake pipe 101 is disrupted. The flow sensor 1011 will quickly detect the abnormal flow change and send a warning signal to the vehicle control system to remind the staff to troubleshoot the fault in time. At the same time, the gas sensor 512 in the manifold 51 will also monitor the gas state entering the filter air guide assembly 5 to help determine the leakage situation.

[0042] After receiving the warning, the vehicle control system opens the valve 533 on the duct 531 and starts the emergency air supply channel. The leak-proof covers 4 at both ends of the air filter 2 will cover the leak point, gather the leaked air and deliver it to the manifold 51 through two branch pipes 511. The manifold 51 concentrates the dispersed airflow and guides it into the air cylinder 521. The filter element 522 in the air cylinder 521 filters the leaked air, removes impurities and contaminants, and the purified air is delivered back to the intake main pipe 101 through the duct 531 and finally enters the air compressor 1 to participate in the compression and air supply. During this process, the gas sensor 512 continuously monitors the gas purity to ensure the filtration effect and prevent impurities from entering the air compressor 1 and causing component wear.

[0043] The emergency response phase provides ample time for staff to conduct maintenance. After the vehicle is parked in a safe location, the air guide 53 can be removed through the detachable connector 532 to clean or replace the filter element 522. At the same time, the connection between the main intake pipe 101, the secondary intake pipe 102 and the air filter 2 is tightened to eliminate the leakage fault. After the fault is eliminated, the valve 533 is closed and the device returns to normal air supply mode.

[0044] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model, and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
