[0025] As people's living standards improve, the demand for more functional vehicles is increasing. Beyond the typical driving needs of cars, there's also a demand for vehicles to offer entertainment while parked. For example, when a vehicle is parked to watch a movie, the vehicle's body can bounce in time with the film's rhythm, creating an immersive viewing experience for occupants. Furthermore, the vehicle's height can be controlled to enhance the driving experience. Therefore, a suspension system is needed to enable vehicle bouncing.

[0026] In order to solve the above technical problems, the present application provides a suspension system, referring to Figure 1 As shown, the hydraulic system comprises a liquid storage device 10, at least one hydraulic shock absorber 20, and at least one hydraulic path 30. The liquid storage device 10 is used to store liquid. Each hydraulic shock absorber 20 has a liquid inlet and outlet 21. Each hydraulic shock absorber 20 is used to connect to a vehicle wheel. Each hydraulic path 30 comprises a liquid inlet pipeline 31, a liquid inlet control valve 32, a liquid inlet and outlet pipeline 33, a liquid outlet pipeline 34, and a liquid outlet control valve 35. The liquid inlet pipeline 31 is connected to the liquid inlet and outlet pipeline 33 through the liquid inlet control valve 32. The liquid inlet and outlet pipeline 33 is connected to the liquid inlet and outlet pipeline 33. The liquid outlet 21 is connected, and the liquid outlet pipeline 34 is connected to the inlet and outlet liquid pipelines 33 through the liquid outlet control valve 35; wherein, when the inlet control valve 32 is on and the outlet control valve 35 is off, the liquid in the liquid storage device 10 enters the hydraulic shock absorber 20 through the liquid inlet pipeline 31 and the inlet and outlet liquid pipelines 33; when the inlet control valve 32 is off and the outlet control valve 35 is on, the liquid in the hydraulic shock absorber 20 exits the hydraulic shock absorber 20 through the inlet and outlet liquid pipelines 33 and the outlet pipeline 34 and enters the liquid storage device 10.

[0027] Thus, when the inlet control valve 32 is open and the outlet control valve 35 is closed, the liquid in the liquid storage device 10 enters the hydraulic shock absorber 20 through the inlet and outlet lines 31 and 33, causing the hydraulic shock absorber 20 to rise, thereby controlling the corresponding portion of the vehicle body to rise. When the inlet control valve 32 is closed and the outlet control valve 35 is open, the liquid in the hydraulic shock absorber 20 exits the hydraulic shock absorber 20 through the inlet and outlet lines 33 and 34 and enters the liquid storage device 10, causing the hydraulic shock absorber 20 to fall, thereby controlling the corresponding portion of the vehicle body to fall. When the hydraulic shock absorber 20 is raised or lowered by controlling the inlet and outlet lines 31 and 35, the vehicle body can be made to bounce, and the bouncing can be coordinated with the rhythm of in-vehicle entertainment, enhancing the user experience of the vehicle. Controlling the vehicle body height can also enhance the driving experience.

[0028] In some embodiments, the suspension system further includes a current throttle valve 40, which is disposed in the inlet and outlet fluid lines 33 and is used to control the raising and lowering speeds of the hydraulic shock absorber 20. The current throttle valve 40 can be remotely controlled to open and close the inlet and outlet fluid lines 33 based on an electrical signal. The current throttle valve 40 automatically eliminates hydraulic imbalances, maintains the desired flow rate, improves system energy efficiency, and achieves energy conservation.

[0029] In some embodiments, the suspension system further includes a first accumulator 41, which is disposed in the inlet and outlet fluid lines 33, located between the current throttle valve 40 and the inlet control valve 32. The first accumulator 41 is used to provide energy to increase the pressure in the inlet and outlet fluid lines 33. The first accumulator 41 is used to store hydraulic or pneumatic energy in the inlet and outlet fluid lines 33, releasing it when needed to provide power support to the hydraulic shock absorber 20. This design ensures sufficient energy when the hydraulic shock absorber 20 needs to be lifted quickly.

[0030] In some embodiments, the liquid storage device 10 includes a first liquid storage device 11 and a second liquid storage device 12. The first liquid storage device 11 is connected to the liquid inlet pipeline 31, and the second liquid storage device 12 is connected to the liquid outlet pipeline 34. The first liquid storage device 11 and the second liquid storage device 12 can be connected to each other, or the first liquid storage device 11 and the second liquid storage device 12 are configured as an integrated structure, so that the oil can be circulated in the suspension system.

[0031] In some embodiments, the suspension system also includes a second accumulator 42 and a first control valve 50. The second accumulator 42 is connected to the first control valve 50, and the first control valve 50 is connected to the liquid inlet line 31. The first control valve 50 is used to control the opening and closing of the second accumulator 42, and the second accumulator 42 is used to provide energy to increase the pressure of the liquid inlet line 31. The second accumulator 42 is used to store the hydraulic energy or air pressure energy in the liquid inlet line 31, and release it when the hydraulic shock absorber 20 needs it to provide power support. Such a design can provide sufficient energy when the hydraulic shock absorber 20 needs to be lifted quickly. Due to the long length of the liquid inlet line 31 and the inlet and outlet lines 33, the mutual cooperation of the first accumulator 41 and the second accumulator 42 can enable the suspension system to have more sufficient lifting energy.

[0032] In some embodiments, the suspension system further includes a power unit 60, which includes a hydraulic pump 61 and a motor 62. The motor 62 and the hydraulic pump 61 are disposed in the inlet line 31, and the motor 62 and the hydraulic pump 61 cooperate to provide power and deliver oil. When the motor 62 and the hydraulic pump 61 are turned on and the inlet control valve 32 is opened, oil is drawn from the liquid reservoir 10 through the inlet line 31 and the inlet and outlet lines 33 and enters the hydraulic shock absorber 20. Once the oil level in the hydraulic shock absorber 20 meets the required level, the motor 62 and the hydraulic pump 61 are stopped and the inlet control valve 32 is closed, thereby maintaining the height of the hydraulic shock absorber 20. When the inlet control valve 32 is closed and the outlet control valve 35 is opened, the oil in the hydraulic shock absorber 20 enters the liquid reservoir 10 through the outlet line 34, and the height of the hydraulic shock absorber 20 is lowered.

[0033] In some embodiments, the suspension system further includes an overpressure protection conduit 70. One side of the overpressure protection conduit 70 is connected to the liquid inlet line 31 and is located between the power unit 60 and the liquid inlet control valve 32. The other side of the overpressure protection conduit 70 is connected to the liquid storage device 10. When the pressure in the suspension system pipeline is too high, the overpressure protection conduit can transfer the oil in the liquid inlet line 31 to the liquid storage device 10, thereby reducing the hydraulic pressure in the liquid inlet line 31.

[0034] In some embodiments, the suspension system further includes a safety relief valve 80, which is disposed in the overpressure protection pipe 70. When the pressure in the liquid inlet line 31 exceeds a set value, the safety relief valve 80 automatically opens, discharging a portion of the liquid in the liquid inlet line 31 into the liquid storage device 10 via the liquid outlet line 34, thereby ensuring that the pressure of the suspension system does not exceed the allowable value, thereby ensuring the safe operation of the suspension system.

[0035] In some embodiments, the suspension system further includes a filter 90 , which is disposed in the liquid inlet line 31 and located between the power device 60 and the liquid storage device 10 . The filter 90 can filter impurities in the liquid storage device 10 and reduce the risk of impurities entering the liquid inlet line 31 .

[0036] In some embodiments, the liquid inlet pipeline 31 includes a liquid inlet main pipe 311 and a liquid inlet branch pipe 312. The liquid inlet main pipe 311 is configured as one, the liquid inlet branch pipe 312 is configured as multiple, the hydraulic shock absorber 20 is configured as multiple, and the inlet and outlet liquid pipelines 33 are configured with multiple corresponding liquid inlet branch pipes 312. The liquid inlet main pipe 311 is respectively connected to multiple liquid inlet branch pipes 312, each liquid inlet branch pipe 312 is correspondingly connected to an inlet and outlet liquid pipeline 33, and each inlet and outlet liquid pipeline 33 is correspondingly connected to a hydraulic shock absorber 20. Specifically, there are four hydraulic shock absorbers 20, each equipped with a liquid inlet branch pipe 312, liquid inlet and outlet pipes 33, and four hydraulic shock absorbers 20. Each hydraulic shock absorber 20 can be raised and lowered, and the four hydraulic shock absorbers 20 do not interfere with each other. When the vehicle body needs to bounce, the corresponding liquid inlet control valve 32 and liquid outlet control valve 35 can be controlled by the vehicle computer to raise or lower the height of the corresponding hydraulic shock absorber 20. When each hydraulic shock absorber 20 bounces to a rhythm, it can cause the vehicle body to bounce, thus coordinating with the rhythm of the movie, improving the viewing experience in the car and, in turn, the driving experience. While the vehicle is in motion, the vehicle body height can also be changed by controlling the hydraulic shock absorbers 20, thereby improving the driving experience.
