[0020] To make the objectives, technical solutions and advantages of the present application more clear and understandable, the following further elaborates on the present application in detail with reference to specific embodiments and the accompanying drawings.

[0022] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0023] As consumers' living standards continue to improve, improving vehicle driving and riding experience has become one of the important goals of current automakers. To this end, many models have introduced adjustable suspensions. With adjustable suspensions, the hardness and height of the suspension can be adjusted according to different road conditions or users' personal preferences to improve vehicle handling and ride comfort. Currently, the common types of adjustable suspensions on the market are mainly mechanical, air, hydraulic and electromagnetic. Among them, hydraulic adjustable suspensions can include a hydraulic lifting system and a body suspension. The hydraulic lifting system can adjust the height and posture of the body suspension by adjusting the fluid medium pressure. The adjustment is stable and has high reliability. Therefore, it is favored by automakers and consumers and is crucial to improving the vehicle's adaptability and driving pleasure.

[0024] However, the current hydraulic lifting system still has the following disadvantages; first, the structure of the hydraulic lifting system is relatively complex, and a large space inside the vehicle is required to install key components in the hydraulic lifting system, so high requirements are placed on the design layout of the vehicle; second, the complex structure will increase the weight of the components in the hydraulic lifting system, which is contrary to the lightweight design concept pursued in the vehicle field; in addition, the cost of components such as the oil supply device in the hydraulic lifting system is relatively high, and daily maintenance is relatively cumbersome, which invisibly increases the manufacturing cost of the vehicle and limits the popularization and application of hydraulic adjustable suspension in a wider range of vehicle models.

[0025] In view of this, the present application provides a hydraulic lifting system based on lubrication of the engine 600, such as Figure 1As shown in the figure, the system includes a liquid supply unit 100, a pressurizing unit 200, and a hydraulic lifting unit 300; the liquid supply unit 100 includes a pump body 110, a first pipeline 120, and a second pipeline 130; the pump body 110 is connected to the engine 600 through the first pipeline 120 and is configured to lubricate the engine 600; the pressurizing unit 200 is connected to the pump body 110 through the second pipeline 130 and is configured to pressurize the fluid medium provided by the pump body 110; the hydraulic lifting unit 300 is connected to the pressurizing unit 200 and is configured to adjust the state of the vehicle body suspension.

[0026] Specifically, as Figure 1 shown in the figure, the present application provides a hydraulic lifting system based on the lubrication of the engine 600, which can both lubricate the engine 600 and adjust the attitude of the vehicle body suspension; more specifically, the hydraulic lifting system may include a liquid supply unit 100, and the liquid supply unit 100 includes a pump body 110, a first pipeline 120, and a second pipeline 130; wherein, the pump body 110 is connected to the engine 600 through the first pipeline 120, and the pump body 110 can be used to transport the fluid medium provided to the pump body 110 to the first pipeline 120, so as to transport the fluid medium to the inside of the engine 600 through the first pipeline 120; exemplarily, the pump body 110 may adopt a device with a transportation function such as a transfer pump, and the fluid medium may adopt a liquid with a lubrication function such as engine oil; when the fluid enters the inside of the engine 600, it can infiltrate some components inside the engine 600 and lubricate the components inside the engine 600 as the engine 600 operates, reducing the wear degree of the engine 600 during operation and ensuring the operating efficiency of the engine 600.

[0027] The hydraulic lifting system further includes a pressurizing unit 200 and a hydraulic lifting unit 300. Among them, the pressurizing unit 200 is connected to the pump body 110 through the second pipeline 130, and the hydraulic lifting unit 300 is connected to the pressurizing unit 200. That is to say, the oil supply system is connected to the engine 600 and the pressurizing unit 200 through the first pipeline 120 and the second pipeline 130 respectively. The engine 600 and the pressurizing unit 200 share the same liquid supply unit 100. Therefore, when the pump body 110 is working, it can separately supply the fluid medium to the engine 600, or supply the fluid medium to the engine 600 and the pressurizing unit 200 simultaneously; as Figure 1As shown, with respect to the hydraulic lifting system, since the pressure of the fluid medium output through the pump body 110 is generally about 2 bar, that is, the pressure of the fluid medium is relatively low, the pump body 110 can be used to deliver the fluid medium provided by the liquid supply unit 100 to the second pipeline 130, and the fluid medium can be delivered to the boosting unit 200 through the second pipeline 130. After the fluid medium enters the boosting unit 200, the boosting unit 200 can be used to pressurize the fluid medium to increase the pressure of the fluid medium and form a high-pressure medium, and then the high-pressure medium is delivered to the hydraulic lifting unit 300, and the hydraulic lifting unit 300 is driven to operate by the high-pressure medium, so that the height and posture of the vehicle body suspension can be controlled by the hydraulic lifting unit 300.

[0028] Therefore, the hydraulic lifting system and the engine 600 can use the same fluid supply unit 100, so that the fluid supply unit 100 can not only continuously lubricate the engine 600, but also provide driving force for the hydraulic lifting unit 300 to adjust the height and posture of the vehicle body suspension, which is beneficial to reduce the complexity of the hydraulic lifting system, reduce the space occupied by the hydraulic lifting system in the vehicle, reduce the cost investment of the vehicle, and help to achieve lightweight design of the vehicle and control production costs.

[0029] It should be noted that the pump body 110 and the fluid medium mentioned above are further explained in combination with the above embodiments; wherein, the pump body 110 can adopt a device with a conveying function such as a conveying pump, which is used to convey the fluid medium to the first pipeline 120 and the second pipeline 130; the fluid medium can adopt a liquid with a lubricating function such as engine oil, and when the fluid medium is engine oil, in addition to being used to lubricate the engine 600, it can also withstand a large pressure, so as to increase the pressure of the fluid medium through the boost unit 200, and ensure that the pressurized fluid medium can drive and adjust the vehicle body suspension after entering the hydraulic lifting unit 300.

[0030] It should be noted that the hydraulic lifting unit 300 mentioned above can be further explained in combination with the above embodiments; wherein, the hydraulic lifting unit 300 may include a right front adjusting suspension, a left front adjusting suspension, a left rear adjusting suspension and a right rear adjusting suspension arranged in the vehicle body. By driving the adjusting suspensions at different positions of the vehicle body, the local height or posture of the vehicle body can be adjusted in a targeted manner, which is conducive to further improving the flexibility and accuracy of the vehicle body suspension adjustment, which will not be repeated here.

[0031] In some embodiments, the boosting unit 200 includes a boosting cylinder 210 and a third pipeline 220; the boosting cylinder 210 is connected to the pump body 110 through the second pipeline 130; the third pipeline 220, the third pipeline 220 is connected to the boosting cylinder 210 and the hydraulic lifting unit 300 respectively.

[0032] likeFigure 1 As shown, in the case of the boosting unit 200, after the fluid supply unit 100 transports the fluid medium to the boosting unit 200 through the second pipeline 130, the boosting unit 200 can be used to pressurize the fluid medium to drive the hydraulic lifting unit 300 to operate, thereby realizing the regulation of the vehicle body suspension; specifically, the boosting unit 200 can include a boosting cylinder 210 and a third pipeline 220. The boosting cylinder 210 is communicated with the pump body 110 through the second pipeline 130, and the third pipeline 220 is communicated with the hydraulic lifting unit 300; after the pump body 110 transports the fluid medium to the boosting cylinder 210 through the second pipeline 130, the boosting cylinder 210 can pressurize the fluid medium to increase the pressure of the fluid medium and form a high-pressure medium, enhancing the driving ability of the fluid medium to meet the driving requirements of the hydraulic lifting unit 300; after the pressurization is completed, the boosting cylinder 210 can transport the high-pressure medium to the hydraulic lifting unit 300 through the third pipeline 220 to provide power for the hydraulic lifting unit 300 through the high-pressure medium, thereby realizing the regulation of the vehicle body suspension.

[0033] In some embodiments, the boosting unit 200 further includes a pressure sensor 230. The pressure sensor 230 is disposed on the third pipeline 220 and is configured to detect the pressure in the third pipeline 220.

[0034] As Figure 1 shown, the boosting unit 200 further includes a pressure sensor 230 for detecting the pressure of the high-pressure medium inside the third pipeline 220. Specifically, after the boosting unit 200 pressurizes the fluid medium to form a high-pressure medium, the high-pressure medium can be transported into the third pipeline 220. At this time, the pressure sensor 230 can be used to detect the pressure in the third pipeline 220, and it can be determined whether the pressurized fluid medium meets the requirements of the hydraulic lifting unit 300 according to the pressure in the third pipeline 220; among them, if the pressure of the fluid medium in the third pipeline 220 is not within the preset pressure range, the pressurization degree of the fluid medium by the boosting cylinder 210 can be adjusted to change the pressure value of the fluid medium in the third pipeline 220 to meet the driving requirements of the hydraulic lifting unit 300, which is beneficial to improving the accuracy of the regulation of the hydraulic lifting system.

[0035] Exemplarily, when the preset pressure range of the fluid medium is 70 bar - 80 bar, it can drive the hydraulic lifting unit 300 to stably control the vehicle body options; for example, increasing the pressure of the fluid medium in the third pipeline 220 to 75 bar, which will not be elaborated here.

[0036] In some embodiments, the fluid supply unit 100 further includes a control switch 140. The control switch 140 is disposed on the second pipeline 130 and is configured to control the on-off state of the second pipeline 130.

[0037] AsFigure 1 As shown, in the case of a hydraulic lifting system, the system can adjust the height and attitude of the vehicle body suspension according to the road conditions of the vehicle's travel and the user's driving habits; among them, the user can control the working state of the hydraulic lifting system by an active control method; specifically, the liquid supply unit 100 can further include a regulation switch 140, and the regulation switch 140 is arranged on the second pipeline 130. When it is necessary to adjust the vehicle body suspension, the regulation switch 140 can be controlled to be turned on, so that the second pipeline 130 is in a through state. At this time, the fluid medium can be conveyed through the second pipeline 130 into the pressurization unit 200 for pressurization. After being pressurized by the pressurization unit 200 to the pressure threshold value, a high-pressure medium is formed, and the hydraulic lifting unit 300 is driven by the high-pressure medium to adjust the vehicle body suspension; when it is not necessary to adjust the vehicle body suspension, the regulation switch 140 can be controlled to be turned off, and the conveyance of the fluid medium into the second pipeline 130 is stopped, reducing the energy consumption of the hydraulic lifting system.

[0038] It should be noted that the regulation switch in the above embodiment can adopt an electric valve body. When an electric valve body is adopted, both the channel state of the second pipeline 130 can be controlled and the flow rate of the fluid medium entering the pressurization unit 200 can be adjusted, which will not be elaborated here.

[0039] In some embodiments, the liquid supply unit 100 further includes a liquid storage device 150, and the liquid storage device 150 is communicated with the pump body 110 and is configured to supply the fluid medium to the pump body 110.

[0040] Regarding the liquid supply unit 100, by using the liquid supply unit 100, the fluid medium can be conveyed into the first pipeline 120 and the second pipeline 130. Through the first pipeline 120, the fluid medium can be conveyed to the engine 600, and the engine 600 can be lubricated, reducing the wear degree of the engine 600. Through the second pipeline 130, the fluid can be conveyed to the pressurization unit 200. After being pressurized by the pressurization unit 200, the hydraulic lifting unit 300 can be driven to adjust the attitude of the vehicle body suspension; as Figure 1 and Figure 2 shown, the liquid supply unit 100 can include a liquid storage device 150, and the fluid medium can be pre-stored by using the liquid storage device 150; and the liquid storage device 150 is communicated with the pump body 110. After controlling the pump body 110 to operate, the pump body 110 can convey the fluid medium from the liquid storage device 150 into the first pipeline 120 and the second pipeline 130 for lubricating the engine 600 and driving the hydraulic lifting unit 300.

[0041] In some embodiments, the hydraulic lifting system further includes a voltage stabilizing unit 400, and the voltage stabilizing unit 400 includes a return pipeline 410 and a pressure limiting switch 420; the return pipeline 410 is respectively communicated with the third pipeline 220 and the liquid storage device 150; the pressure limiting switch 420 is arranged on the return pipeline 410.

[0042] After the fluid medium is conveyed to the pressurization unit 200, the fluid medium can be pressurized by the pressurization unit 200 to form a high-pressure medium, and then conveyed to the hydraulic lifting unit 300 through the third pipeline 220, so as to regulate the vehicle body suspension through the hydraulic lifting unit 300; as Figure 1 shown, the hydraulic lifting system further includes a pressure stabilizing unit 400. When the pressure in the third pipeline 220 is too high, the pressure stabilizing unit 400 can be used to adjust the pressure of the high-pressure medium in the third pipeline 220, accelerate the pressure reduction speed, and maintain the stability of the pressure in the third pipeline 220.

[0043] Among them, the pressure stabilizing unit 400 includes a return pipeline 410 and a pressure limiting switch 420. The return pipeline 410 is respectively communicated with the third pipeline 220 and the liquid storage tank 150, and the pressure limiting switch 420 is arranged on the return pipeline 410; specifically, when the pressure in the third pipeline 220 is greater than the maximum threshold of the preset pressure range set in advance, the higher pressure regulation range is larger and not easy to control, and at the same time, it may also cause damage to the hydraulic lifting unit 300. By arranging the pressure limiting switch 420 on the third pipeline 220, it can be opened when the pressure in the third pipeline 220 is greater than the maximum threshold of the preset pressure range, so that the high-pressure medium in the third pipeline 220 flows back into the liquid storage tank 150 through the return pipeline 410. As the high-pressure medium in the third pipeline 220 decreases, the pressure in the third pipeline 220 gradually decreases, and when the pressure in the third pipeline 220 drops to the preset threshold within the preset pressure range, the pressure limiting switch 420 can be controlled to close to maintain the stability of the pressure in the third pipeline 220, which is beneficial to realizing the stable drive of the hydraulic lifting unit 300 and can improve the safety of the operation of the hydraulic lifting system.

[0044] It should be noted that the pressure limiting switch 420 is further described in combination with the above embodiments. The pressure limiting switch 420 can adopt a pressure limiting valve, and the pressure limiting valve can be opened when the pressure value is greater than the maximum threshold of the preset pressure range and closed when it drops to the preset threshold within the preset pressure range to maintain the stability of the internal pressure of the third pipeline 220, which will not be elaborated here.

[0045] In some embodiments, the hydraulic lifting system further includes a pressure relief unit 500. The pressure relief unit 500 includes a pressure relief pipeline 510 and a pressure relief switch 520; the pressure relief pipeline 510 is respectively communicated with the third pipeline 220 and the liquid storage tank 150; the pressure relief switch 520 is arranged on the pressure relief pipeline 510.

[0046] After the fluid supply unit 100 conveys the fluid medium to the pressurization unit 200, the pressurization unit 200 can pressurize the fluid medium to form a high-pressure medium, and then convey it to the hydraulic lifting unit 300 through the third pipeline 220 to drive the hydraulic lifting unit 300 to adjust the vehicle body suspension; as Figure 1 shown, the hydraulic lifting system may further include a pressure relief unit 500. The pressure relief unit 500 includes a pressure relief pipeline 510 and a pressure relief switch 520. The pressure relief pipeline 510 is respectively communicated with the third pipeline 220 and the liquid storage tank 150. The pressure relief switch 520 is arranged on the pressure relief pipeline 510 and can release the fluid medium in the third pipeline 220 into the liquid storage tank 150 for reuse after adjusting the vehicle body suspension, so as to drive the hydraulic lifting system to adjust the vehicle body options subsequently.

[0047] Specifically, when driving the hydraulic lifting unit 300 with the high-pressure medium in the third pipeline 220, the pressure relief switch 520 can be kept closed to ensure the driving effect of the high-pressure medium on the hydraulic lifting unit 300; when it is necessary to reduce the pressure in the third pipeline 220 or release the high-pressure medium in the third pipeline 220, the pressure relief switch 520 on the pressure relief pipeline 510 can be controlled to open, so that the high-pressure medium in the third pipeline 220 flows into the liquid storage tank 150 through the pressure relief pipeline 510, thereby achieving the purpose of rapid pressure relief or releasing the high-pressure medium.

[0048] It should be noted that the pressure relief switch 520 in the above embodiment can adopt an electric valve body. When an electric valve body is adopted, both the channel state of the pressure relief pipeline 510 and the pressure relief speed of the pressure relief pipeline 510 can be controlled, which will not be elaborated here.

[0049] In some embodiments, a plurality of fins 151 for heat dissipation are uniformly arranged on the outer side wall of the liquid storage tank 150.

[0050] Regarding the hydraulic lifting unit 300, when pressurizing the fluid medium by the pressurizing cylinder 210, the fluid medium can be formed into a high-pressure medium. Compared with the unpressurized fluid medium, the temperature of the high-pressure medium is higher. Therefore, when the high-pressure medium flows back to the inside of the liquid storage tank 150 through the pressure relief unit 500 or the pressure stabilizing unit 400, it will cause the overall temperature of the liquid storage tank 150 to rise, which is not conducive to the normal operation of the pump body 110 and affects the lubrication effect on the engine 600. Therefore, it is necessary to cool the liquid storage tank 150 to reduce the temperature of the fluid medium in the liquid storage tank 150; as Figure 2As shown, by evenly arranging a plurality of fins 151 for heat dissipation on the outer wall of the liquid reservoir 150, the heat dissipation area of the liquid reservoir 150 can be increased, the heat dissipation capacity of the liquid reservoir 150 can be improved, which is beneficial for the fluid medium in the liquid reservoir 150 to quickly dissipate heat to the external environment, so as to ensure the stable operation of the pump body 110 and ensure the lubrication effect of the fluid medium on the engine 600.

[0051] In some embodiments, the liquid reservoir 150 is provided with a liquid level gauge 152, and the liquid level gauge 152 is configured to detect the liquid level inside the liquid reservoir 150.

[0052] To ensure that the hydraulic lifting system can continuously lubricate the engine 600 and has sufficient fluid medium to drive the hydraulic lifting system to operate, sufficient fluid medium needs to be pre-stored in the liquid reservoir 150; as Figure 1 and Figure 2 shown, by arranging a liquid level gauge 152 in the liquid reservoir 150, the liquid level of the fluid medium in the liquid reservoir 150 can be detected in real time, so that the user can timely supplement the fluid medium in the liquid reservoir 150 according to the detected liquid level situation, so as to ensure the stable operation of the engine 600 and the hydraulic lifting system.

[0053] Based on the same inventive concept, the present application also provides a vehicle, including the hydraulic lifting system based on engine lubrication described in the above embodiments; wherein, since the vehicle includes the hydraulic lifting system described above, the vehicle can solve the technical problems to be solved by the hydraulic lifting system described above and has all the technical effects and advantages of the hydraulic lifting system described above, which will not be elaborated here.
