Description

Technical Field

[0001] This invention belongs to the field of automotive mounting system technology, specifically relating to a mounting system for an air compressor. Background Technology

[0002] An automotive air compressor is a key component of an air supply system. It converts the mechanical energy of a prime mover into gas pressure energy and acts as a pressure generator for compressed air. An air compressor is a device used to compress gases.

[0003] Its main function is to compress and drive the refrigerant. In other words, with the help of the car engine, the car compressor compresses the refrigerant vapor in the air conditioning evaporator into refrigerant vapor, which is then discharged through the air conditioning pipes to the air conditioning condenser. This provides the high pressure conditions for the refrigerant vapor to condense and release heat in the condenser. During this process, the car compressor also overcomes the circulation resistance in the refrigeration system.

[0004] However, the air compressor in a car will vibrate when it starts up, which will affect its use. Therefore, a suspension system is installed at the connection between the air compressor and the vehicle body. The suspension system is used to reduce and control the transmission of compressor vibration and to support the powertrain. Usually, by optimizing the design of the air compressor and the vehicle body suspension, the purpose of absorbing vibration and reducing noise can be achieved.

[0005] Existing suspension systems generally include rubber suspensions, hydraulic suspensions, and air suspensions, with hydraulic suspensions being the most commonly used. Hydraulic suspensions are filled with flowing fluid. This system works by replacing ordinary shock absorbers with hydraulic cylinders. Hydraulic suspensions are automotive powertrain components used to reduce and control the transmission of engine vibrations and provide support.

[0006] However, existing hydraulic suspension systems cannot identify whether the problem lies in the installation of the hydraulic suspension or damage to the main spring inside the hydraulic suspension, making maintenance inconvenient. Therefore, a suspension system for an air compressor is designed that can determine whether the problem lies in the installation of the hydraulic suspension or damage to the main spring inside the hydraulic suspension when the air compressor is started, making it easier for staff to perform maintenance. Summary of the Invention

[0007] The purpose of this invention is to provide a suspension system for an air compressor for existing material collection devices, in order to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a suspension system for an air compressor, comprising a hydraulic suspension and a hydraulic suspension control system, wherein the hydraulic suspension includes a top cover, a base, and a main spring, wherein: The main spring is disposed between the upper cover and the base, the upper cover and the base are fixedly connected, the base is mounted on the vehicle body, and a connecting bracket is fixed on one side of the main spring. The connecting bracket has a mounting hole for fixing to the air compressor. The main spring has a storage cavity inside, which stores flowing liquid. A hydraulic cylinder is provided on one side of the hydraulic suspension, and a piston is provided inside the hydraulic cylinder. A linear drive is connected to the piston. An inlet pipe and an outlet pipe are connected to one side of the hydraulic cylinder and the storage chamber. A hydraulic gauge is connected to the inlet pipe. A distance sensor is fixed on the right side of the piston.

[0009] The present invention further illustrates that a first check valve is connected to the inlet pipe and a second check valve is connected to the outlet pipe.

[0010] The present invention further illustrates that a vibration damping seat is fixed at the bottom of the base, both the vibration damping seat and the main spring are made of rubber, and a fixing plate is provided below the vibration damping seat, the fixing plate being fixedly connected to the base.

[0011] The present invention further explains that the hydraulic suspension control system includes a data acquisition module and a control module. The data acquisition module includes a frequency detection submodule, a judgment submodule, a hydraulic receiving submodule, and a length receiving submodule. The frequency detection submodule is electrically connected to the air compressor and is used to detect the vibration frequency of the air compressor. The judgment submodule is used to determine whether the main spring is damaged. The hydraulic receiving submodule is electrically connected to the hydraulic gauge. The length receiving submodule is electrically connected to the distance sensor and is used to detect the distance between the piston and the right side of the hydraulic cylinder.

[0012] The present invention further explains that the control module includes a liquid inlet control submodule, a liquid outlet control submodule, and a prompting submodule. The liquid inlet control submodule is electrically connected to the linear drive and is used to input liquid in the hydraulic cylinder into the storage chamber. The liquid outlet control submodule is electrically connected to the linear drive and is used to pump liquid in the storage chamber into the hydraulic cylinder. The prompting submodule is used to provide a prompting effect.

[0013] The present invention further illustrates that the hydraulic suspension control system includes the following operating steps: Step 1: When the air compressor starts, the vibration frequency of the air compressor is detected by the frequency detection submodule; Step 2: Based on the vibration frequency of the air compressor, increase the hydraulic pressure of the liquid flowing in the storage chamber of the main spring to reduce the vibration frequency of the hydraulic suspension. Step 3: When the flow of liquid hydraulic pressure in the storage chamber of the main spring is increased, the vibration frequency of the air compressor is judged again to determine whether the air compressor vibration reduction is successful.

[0014] The present invention further explains that step three includes the following specific operational steps: Step 3-a: Detect the vibration frequency of the air compressor again through the frequency detection submodule to continue identifying the vibration frequency of the air compressor; Step 3-b: When the vibration frequency is high, it indicates that the vibration reduction treatment is complete, meaning that there is no problem with the quality of the hydraulic suspension. Step 3-c: If the vibration frequency is still low, it means that the air compressor is still vibrating. Further identification of the air compressor vibration is needed to facilitate further handling and maintenance by staff.

[0015] The present invention further explains that step three-c includes the following specific operational steps: Step 3-c: Use a hydraulic gauge to monitor the hydraulic pressure in the inlet pipe in real time to determine if there is any damage inside the storage chamber; Step 3-c: When the storage cavity is damaged but does not penetrate the entire main spring, a signal is transmitted to the prompting submodule to inform the staff that there is a problem with the storage cavity and to replace it in time after the vehicle body's travel is completed; Step 3-c: When the storage cavity penetrates the entire main spring, a signal is transmitted to the prompting submodule to inform the user to replace it in time and to empty the flowing liquid in the storage cavity in time to prevent it from flowing out too much and affecting the use of other equipment in the vehicle.

[0018] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-2 The present invention provides a technical solution: a suspension system for an air compressor, including a hydraulic suspension and a hydraulic suspension control system. The hydraulic suspension includes an upper cover 1, a base 2, and a main spring 6. The main spring 6 is disposed between the upper cover 1 and the base 2. The upper cover 1 and the base 2 are fixedly connected. The base 2 is mounted on the vehicle body. A connecting bracket 3 is fixed to one side of the main spring 6. The connecting bracket 3 has a mounting hole for fixing to the air compressor. When the air compressor starts, the main spring 6 can reduce the transmission of air compressor vibration. When the hydraulic suspension is installed with the air compressor, the hydraulic suspension is provided with at least two sets fixed to the air compressor.

[0020] The main spring 6 has a storage cavity 4 inside, which can store flowing liquid. A vibration damping seat 7 is fixed at the bottom of the base 2. Both the vibration damping seat 7 and the main spring 6 are made of rubber. A fixing plate 8 is set below the vibration damping seat 7. The fixing plate 8 is fixedly connected to the base 2. The vibration damping seat 7 can further play a vibration damping role.

[0021] Please see Figure 3 A hydraulic cylinder 9 is provided on one side of the hydraulic suspension. A piston 14 is provided inside the hydraulic cylinder 9. A linear drive is connected to the piston 14, which can be activated to move the piston 14 inside the hydraulic cylinder 9. One side of the hydraulic cylinder 9 is connected to the storage chamber 4 by an inlet pipe 10 and an outlet pipe 11. A first check valve 12 and a hydraulic gauge 5 are connected to the inlet pipe 10. A second check valve 13 is connected to the outlet pipe 11. A distance sensor 15 is fixed on the right side of the piston 14. The first check valve 12 is provided to prevent the flowing liquid from flowing back into the hydraulic cylinder 9, and the second check valve 13 is provided to prevent the liquid from flowing back into the storage chamber 4.

[0022] The hydraulic suspension control system includes a data acquisition module and a control module. The data acquisition module includes a frequency detection submodule, a judgment submodule, a hydraulic receiving submodule, and a length receiving submodule. The frequency detection submodule is electrically connected to the air compressor and is used to detect the vibration frequency of the air compressor. The judgment submodule is used to determine whether the main spring 6 is damaged. The hydraulic receiving submodule is electrically connected to the hydraulic gauge 5. The length receiving submodule is electrically connected to the distance sensor 15 and is used to detect the distance between the piston 14 and the right side of the hydraulic cylinder 9. The control module includes a liquid inlet control submodule, a liquid outlet control submodule, and a prompting submodule. The liquid inlet control submodule is electrically connected to the linear drive and is used to input the liquid in the hydraulic cylinder 9 into the storage chamber 4. The liquid outlet control submodule is electrically connected to the linear drive and is used to pump the liquid in the storage chamber 4 into the hydraulic cylinder 9. The prompting submodule is used to provide a prompting effect.

[0023] The hydraulic suspension control system includes the following operating steps: Step 1: When the air compressor starts, the vibration frequency of the air compressor is detected by the frequency detection submodule; Specifically, the vibration frequency level of the air compressor is set in the frequency detection submodule, and the real-time detected vibration frequency of the air compressor is compared with the set level to identify the magnitude of the air compressor's vibration frequency.

[0024] Step 2: Based on the vibration frequency of the air compressor, increase the hydraulic pressure of the liquid flowing in the storage chamber 4 within the main spring 6 to reduce the vibration frequency of the hydraulic suspension. Specifically, when the vibration frequency of the air compressor is high, it indicates that there is no problem with the hydraulic suspension. When the vibration frequency of the air compressor is low, the signal is transmitted to the liquid inlet control submodule to start the linear drive, push the piston 14 to move inside and squeeze the flowing liquid into the storage chamber 4, increase the hydraulic pressure in the storage chamber 4, and reduce the vibration of the air compressor. It should be noted that when the linear drive piston 14 squeezes the flowing liquid into the storage chamber 4, the hydraulic gauge 5 detects the hydraulic pressure value in the inlet pipe 10 in real time and transmits it to the hydraulic receiving submodule. When the hydraulic receiving submodule detects that the hydraulic pressure value has reached a constant value and has not increased, it sets the constant value to c, indicating that the flowing liquid in the storage chamber 4 has reached its upper limit. At this time, the linear drive is paused, which also indicates that the storage chamber 4 in the hydraulic suspension is not damaged.

[0025] Step 3: When the flow of liquid hydraulic pressure in the storage chamber 4 of the main spring 6 is increased, the vibration frequency of the air compressor is judged again to determine whether the air compressor vibration reduction is successful.

[0026] Step three includes the following specific operational steps: Step 3-a: Detect the vibration frequency of the air compressor again through the frequency detection submodule to continue identifying the vibration frequency of the air compressor; Step 3-b: When the vibration frequency is high, it indicates that the vibration reduction treatment is complete, meaning that there is no problem with the quality of the hydraulic suspension. Step 3-c: If the vibration frequency is still low, it means that the air compressor is still vibrating. Further identification of the air compressor vibration is needed to facilitate further handling and maintenance by staff. Step 3-c includes the following specific operational steps: Step 3-c1: Use hydraulic gauge 5 to monitor the hydraulic pressure in the inlet pipe 10 in real time to determine whether there is any damage in the storage chamber 4; When the hydraulic receiving submodule detects that the hydraulic value has reached a constant value c and has not increased, but the air compressor is still vibrating at a high frequency, it indicates that there may be a loose connection between the hydraulic mount and the vehicle body. At this time, the signal is transmitted to the prompting submodule to inform the staff to stop the air compressor from starting and to better fix the hydraulic mount to the vehicle body. Furthermore, when piston 14 moves, distance sensor 15 detects the distance between piston 14 and hydraulic cylinder 9 in real time and transmits it to the length receiving submodule. When hydraulic gauge 5 is at a constant value c, the distance between piston 14 and hydraulic cylinder 9 is a, proving that the flowing liquid in hydraulic cylinder 9 enters the storage chamber 4 at a fixed value. If hydraulic gauge 5 detects a constant value c, but distance sensor 15 detects a distance between piston 14 and hydraulic cylinder 9 greater than a, it indicates that the amount of flowing liquid entering the storage chamber 4 is large, indicating that there is a gap around the storage chamber 4, but the gap has not penetrated the main spring 6. If the air compressor still vibrates at a low frequency at this time, it indicates that there is damage inside the storage chamber 4, but it does not affect the effect of reducing the vibration transmission of the air compressor. If the storage chamber 4 is damaged, and the air compressor still vibrates at a high frequency, it indicates that not only is the storage chamber 4 damaged, but the hydraulic mount may also be loose. In this case, the hydraulic mount needs to be replaced. Furthermore, if the linear drive is continuously running, and the hydraulic value detected by the hydraulic gauge 5 in real time never reaches the constant value c, and the distance sensor 15 detects that the distance between the piston 14 and the hydraulic cylinder 9 is greater than a, it indicates that the storage cavity 4 is damaged and penetrates the entire main spring 6, and there is a possibility of leakage. Therefore, the hydraulic pressure in the storage cavity 4 can never be filled, resulting in poor vibration damping effect of the hydraulic suspension.

[0027] Step 3-c2: When the storage cavity 4 is damaged but does not penetrate the entire main spring 6, a signal is transmitted to the prompting submodule to inform the staff that there is a problem with the storage cavity 4 and that it should be replaced in time after the vehicle body travels out.

[0028] Step 3 - c3: When the storage cavity 4 penetrates the entire main spring 6, a signal is transmitted to the prompting submodule to inform the user to replace it in time and to empty the flowing liquid in the storage cavity 4 in time to avoid it flowing out too much and affecting the use of other equipment in the vehicle. Specifically, emptying the flow in the storage chamber 4 also involves transmitting a signal to the liquid control submodule to control the linear drive valve to pump the liquid in the storage chamber 4 into the hydraulic cylinder 9 through the liquid outlet pipe 11, thus preventing excessive leakage of the liquid in the storage chamber 4.

[0029] By following the steps above, the vibration of the air compressor can be analyzed, and different maintenance measures can be taken according to different situations, which facilitates maintenance by personnel and eliminates the need to find the cause of the air compressor vibration.
