DETAILED DESCRIPTION

[0041] The present application will be further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are intended to be illustrative only and not limiting of the present application. In addition, it should be noted that for the sake of brevity, only portions of the drawings are shown in the figures.

[0042] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other in the case of no conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments. In addition, the term "and / or" in this paper is only to describe the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. The terms "first" and "second" in the specification and claims of the embodiments of the present application are used to distinguish different objects, not to describe the specific order of the objects.

[0043] FIG. 1 is an implementation environment architecture diagram of a damping system according to an embodiment of the present application. As shown in FIG. 1, the implementation environment architecture can be, for example, an air suspension system, and can specifically include at least one damper 101, an air tank 102, and an air supply machine 103. Among them, one end of the air tank 102 is in communication with the air supply machine 103, and the other end of the air tank 102 is in communication with the damper 101 respectively.

[0044] For example, the damper 101, the air tank 102, and the air supply machine 103 described above can be in communication through a charging pipeline. Specifically, the air supply machine 103 can be used to charge the air tank 102 with gas first, so that the air tank 102 can store a preset amount of gas; and then the air tank 102 can be used to charge the damper 101 with gas respectively, so that the internal air pressure of the damper 101 can reach a normal state.

[0045] For example, the damper 101 described above can be composed of an air bag and a damper, so as to adjust the internal air pressure of the air bag through the damper to realize the damping function of the damper itself; and the air supply machine 103 can be driven by an electric motor, so as to compress external air by the electric motor and then transmit the compressed air.

[0046] At present, in order to reduce the body vibration of the vehicle during driving, a damper 101 is usually installed in the vehicle to reduce the body vibration, so as to improve the comfort degree of passengers when riding the vehicle. However, in order to realize the damping function of the vehicle under different vehicle conditions, the internal air pressure of the existing vehicle damper 101 can gradually increase in the process of long-term use, thereby causing unstable damping performance.

[0047] For example, when the vehicle is driven on a poor road for a long time, the gas pressure in the damper 101 can gradually decrease, thereby causing problems such as damping force attenuation, abnormal noise, etc. in the damper 101; and after the vehicle is continuously driven for a long time, the temperature in the damper 101 can gradually increase, thereby causing the internal pressure of the damper 101 to gradually increase, and causing problems such as oil leakage and failure of the damper 101. Therefore, the damping performance of the existing vehicle damper 101 still has the technical problem of poor stability.

[0048] Based on this, the application provides a damping system 20, which can adjust the internal air pressure of the damper by using the air supply machine when the internal air pressure of the damper is in an abnormal state, so as to keep the internal air pressure of the damper in a normal state at all times, thereby guaranteeing the stability of the damping performance of the damper.

[0049] In an embodiment of the application, the damping system 20 comprises at least one damper 21 and an air supply machine 22; the cavity of the damper 21 is provided with a sensor 211; the damper 21 is further provided with a control valve 212, one end of the control valve 212 being in communication with the air port of the damper 21, and the other end being in communication with the air supply machine 22.

[0050] Specifically, the sensor 211 is used to monitor the air pressure state in the damper 21, and send an abnormal signal when the internal air pressure of the damper 21 is in an abnormal state; the air supply machine 22 is used to exchange gas with the damper 21 through the opening degree of the control valve 212 in response to the abnormal signal sent by the sensor 211.

[0051] In the embodiment of the application, when the damper 21 receives an external force, the damper 21 can provide a damping force opposite to the direction of the force through its own components, thereby achieving the effect of damping. However, when the internal air pressure of the damper 21 is abnormal, the damping force provided by the damper 21 will change, thereby causing the damping effect to be abnormal.

[0052] In a possible implementation, the damper 21 can comprise an elastic component and a damper; wherein the damper can be fixedly connected with the elastic component. Specifically, the elastic component can be used to deform under the action of an external force, and drive the damper to be in an operating state; the damper can be used to provide a damping force corresponding to the external force under the driving of the elastic component.

[0053] For example, the elastic component 32 can be an air spring component.

[0054] Specifically, the top seat component 31 can comprise a top seat and a support. Wherein the top seat is provided with a containing cavity, and the support is provided with a through hole; part of the structure of the top seat can be sleeved inside the through hole and detachably connected with the support.

[0055] In addition, FIG. 3 is another structural schematic diagram of the damper 21 provided by the application. As shown in FIG. 3, the damper 21 can comprise a top seat component 41 and an elastic component 42.

[0056] In a possible implementation, the damper 21 can monitor the air pressure state inside the damper 21 through the sensor 211, and can control the opening and closing state of the air port of the damper 21 through the control valve 212.

[0057] For example, the sensor 211 can be arranged inside the damper of the damper 21, and the control valve 212 can be arranged at the air port of the damper.

[0058] It should be noted that the sensor 211 and the control valve 212 are arranged on the damper of the damper 21 because the damper 21 mainly achieves the damping effect through the internal damper; and in the process of achieving the damping effect by the damper, the damper needs to maintain a normal and stable air pressure state inside. Therefore, the sensor 211 needs to be arranged inside the damper to monitor the air pressure state inside the damper, and the control valve 212 needs to be arranged at the air port of the damper to control the filling and discharge of the gas inside the damper.

[0059] In a possible implementation, when the sensor 211 monitors that the air pressure state inside the damper 21 is in an abnormal state, the sensor 211 can send an abnormal signal to represent that the air pressure inside the damper 21 is abnormal.

[0060] For example, the air pressure state inside the damper 21 can include high pressure, low pressure, and stable pressure. Specifically, when the air pressure value inside the damper 21 is greater than a preset air pressure value, the damper 21 is in a high pressure state; when the air pressure value inside the damper 21 is less than the preset air pressure value, the damper 21 is in a low pressure state; and when the air pressure value inside the damper 21 is equal to the preset air pressure, the damper 21 is in a stable pressure state. It should be noted that when the air pressure state inside the damper 21 is in a high pressure state or a low pressure state, it can be determined that the air pressure inside the damper 21 is in an abnormal state.

[0061] For example, the sensor 211 can be used to obtain the specific air pressure value inside the damper 21 in real time, and send an abnormal signal when the air pressure value is greater than or less than the air pressure value. The sensor 211 can be a pressure sensor. For example, when the sensor 211 is a piezoresistive pressure sensor, a silicon single crystal plate can be used as a pressure receiving element, a resistance bridge circuit can be formed by diffusing impurities on the surface of the silicon single crystal plate, and the air pressure value can be calculated by using the resistance value change.

[0062] For example, the damping system 20 can further include a processing unit. When the sensor 211 monitors that the air pressure inside the damper 21 is in an abnormal state, the sensor 211 can send an abnormal signal to the processing unit.

[0063] In a possible implementation, the gas supply machine 22 can be used to exchange the gas inside the damper 21, so as to change the air pressure state inside the damper 21.

[0064] It should be noted that when the processing unit of the damping system 20 obtains the abnormal signal sent by the sensor 211, the processing unit can send a control signal to the gas supplier 22 to control the gas supplier 22 to start to implement gas exchange with the gas inside the damper 21.

[0065] For example, the processing unit can send a control signal to the gas supplier 22 according to the specific type of the abnormal signal sent by the sensor 211, so that the gas supplier 22 can transmit the gas with the corresponding attribute to the inside of the damper 21 through the control valve 212. For example, the gas supplier 22 can transmit the gas with the opposite state to the current gas pressure state inside the damper 21 to the inside of the damper 21.

[0066] For example, when the gas supplier 22 transmits the gas to the inside of the damper 21 through the control valve 212, the control valve 212 can be opened by the pressure difference between the transmitted gas and the gas inside the damper 21, so that the transmitted gas enters the inside of the damper 21 through the opened control valve 212.

[0067] Specifically, the opening degree of the control valve 212 can be positively correlated with the pressure difference between the transmitted gas and the gas inside the damper 21. The greater the pressure difference between the transmitted gas and the gas inside the damper 21, the greater the opening degree of the control valve 212.

[0068] Compared with the damping system in the prior art, the damping system 20 provided by the embodiment of the present application can obtain the gas pressure state inside the damper 21 in real time by using the sensor 211 inside the damper 21, so as to send an abnormal signal in time when the gas pressure inside the damper 21 is abnormal, thereby processing the abnormal problem of the damper 21 in time. On the other hand, in response to the abnormal signal sent by the sensor 211, the gas supplier 22 can exchange the corresponding gas with the damper 21 based on the specific abnormal condition of the gas pressure inside the damper 21, so that the gas pressure inside the damper 21 can always be kept in a normal state, thereby ensuring the stability of the damping performance of the damper 21.

[0069] In another embodiment of the present application, the specific structure and implementation of the gas supplier 22 are also introduced. For example, the gas supplier 22 is provided with a transmission control valve 221.

[0070] Specifically, the gas supplier 22 is configured to open the transmission control valve 221 to input the gas into the damper 21 when the abnormal signal indicates that the internal gas pressure of the damper 21 is lower than the preset gas pressure; and is also configured to open the transmission control valve 221 to discharge the internal gas of the damper 21 when the abnormal signal indicates that the internal gas pressure of the damper 21 is higher than the preset gas pressure.

[0071] In the embodiments of the present application, the gas supplier 22 can input gas into the damper 21 or make the damper 21 exhaust gas by opening the transmission control valve 221, so as to adjust the gas pressure state in the damper 21, thereby keeping the gas pressure in the damper 21 stable.

[0072] In a possible implementation, when the processing unit of the damping system 20 obtains the abnormal signal sent by the sensor 211, the transmission control valve 221 can be opened to exchange gas with the damper 21.

[0073] It should be noted that when the transmission control valve 221 is in the open state, the gas supplier 22 can transmit the internal compressed gas to the outside.

[0074] For example, FIG. 4 is a structural schematic diagram of the gas supplier 22 provided by the embodiments of the present application. As shown in FIG. 4, the gas supplier 22 can include the transmission control valve 221, the compressor 222, and the noise reduction assembly 223. Specifically, the transmission control valve 221 can be used to control the gas path to be in a communication state or a cutoff state; the compressor 222 can be used to compress external air to provide gas pressure energy; and the noise reduction assembly 223 can be used to reduce noise and vibration, which can be an acoustic cover.

[0075] For example, the transmission control valve 221 can receive the control signal sent by the processing unit to control the communication or cutoff of the gas supplier 22 and the internal gas path of the damper 21.

[0076] For example, when the internal gas pressure of the damper 21 is lower than the preset gas pressure, the gas supplier 22 can input gas into the damper 21 by opening the transmission control valve 221, so as to increase the internal gas pressure of the damper 21; for example, the gas supplier 22 can input high-pressure gas into the damper 21.

[0077] Optionally, when the internal gas pressure of the damper 21 is higher than the preset gas pressure, the gas supplier 22 can make the damper 21 exhaust internal gas by opening the transmission control valve 221, so as to reduce the internal gas pressure of the damper 21; for example, the gas supplier 22 can input negative-pressure gas into the damper 21.

[0078] In another embodiment of the present application, the specific structure of the control valve 212 is also introduced. For example, FIG. 5 is a structural schematic diagram of the control valve 212 provided by the embodiments of the present application. As shown in FIG. 5, the control valve 212 includes a first cavity 2121, a second cavity 2122, a first one-way sub-valve 2123, and a second one-way sub-valve 2124; the first cavity 2121 is in communication with the inside of the damper 21; and the gas supplier 22 is in communication with the second cavity 2122.

[0079] Specifically, one end of the first one-way sub-valve 2123 is in communication with the first chamber 2121, and the other end of the first one-way sub-valve 2123 is isolated from the second chamber 2122 by the first sealing assembly 2125; one end of the second one-way sub-valve 2124 is in communication with the second chamber 2122, and the other end of the second one-way sub-valve 2124 is isolated from the first chamber 2121 by the second sealing assembly 2126.

[0080] In the embodiments of the present application, the control valve 212 can utilize the first one-way sub-valve 2123 and the second one-way sub-valve 2124 to respectively realize the filling and discharge of the gas inside the shock absorber 21, and utilize the first sealing assembly 2125 and the second sealing assembly 2126 to ensure the stability of the gas inside the shock absorber 21.

[0081] For example, as shown in FIG. 5, the first one-way sub-valve 2123 and the second one-way sub-valve 2124 can respectively include a first limit spring 501 and a second limit spring 502. For example, the first one-way sub-valve 2123 can be provided with a first one-way sub-valve base 503 at the end close to the first chamber 2121, and the second one-way sub-valve 2124 can be provided with a second one-way sub-valve base 504 at the end close to the second chamber 2122. For example, the first one-way sub-valve 2123 and the second one-way sub-valve 2124 can be a normally closed one-way valve.

[0082] Specifically, when filling the gas inside the shock absorber 21, the first sealing assembly 2125 is opened; when discharging the gas inside the shock absorber 21, the second sealing assembly 2126 is opened.

[0083] In another embodiment of the present application, an embodiment of the exchange of gas between the shock absorber 21 and the gas supplier 22 is also introduced. For example, when the abnormal signal is used to represent that the internal gas pressure of the shock absorber 21 is lower than the preset gas pressure, the gas supplier 22 opens the transmission control valve 221 and outputs high-pressure gas to the second chamber 2122, so as to open the first sealing assembly 2125 by using the pressure difference between the internal gas pressure of the shock absorber 21 and the high-pressure gas, and the high-pressure gas enters the shock absorber from the first chamber 2121.

[0084] In a possible implementation, when the abnormal signal emitted by the sensor 211 is used to represent that the internal gas pressure of the shock absorber 21 is lower than the preset gas pressure, the processing unit can send a control signal to the gas supplier 22 to control the gas supplier 22 to output high-pressure gas.

[0085] For example, as shown in FIG. 5, when the high-pressure gas enters the second chamber 2122 from the gas supplier 22, due to the low internal gas pressure of the shock absorber 21, the high-pressure gas can enter the gas inlet channel 505 and open the first sealing assembly 2125 under the action of the pressure difference, so as to enter the first chamber 2121 through the first limit spring 501, and then enter the shock absorber 21.

[0086] It should be noted that when the high-pressure gas enters the shock absorber 21, the high-pressure gas can mix with the existing gas in the shock absorber 21, thereby increasing the internal pressure of the shock absorber 21.

[0087] In another embodiment of the present application, another embodiment of the gas exchange between the shock absorber 21 and the gas supplier 22 is introduced. For example, when the abnormal signal is used to represent that the internal pressure of the shock absorber is higher than the preset pressure, the gas supplier 22 opens the transmission control valve 221 and outputs the negative-pressure gas to the second chamber 2122, so as to open the second sealing assembly 2126 by using the pressure difference between the internal pressure of the shock absorber 21 and the negative-pressure gas, and the gas in the shock absorber 21 is discharged from the shock absorber 21 through the second chamber 2122.

[0088] In a possible implementation, when the abnormal signal emitted by the sensor 211 is used to represent that the internal pressure of the shock absorber 21 is higher than the preset pressure, the processing unit can send a control signal to the gas supplier 22 to control the gas supplier 22 to output the negative-pressure gas.

[0089] For example, as shown in FIG. 5, when the negative-pressure gas enters the second chamber 2122 from the gas supplier 22, due to the higher internal pressure of the shock absorber 21, the gas in the shock absorber 21 can enter the exhaust passage 506 from the first chamber 2121 under the action of the pressure difference, and the second sealing assembly 2126 is opened, so as to enter the second chamber 2122 through the second limiting spring 502, thereby being discharged from the shock absorber 21.

[0090] It should be noted that when the negative-pressure gas enters the shock absorber 21, the high-pressure gas in the shock absorber 21 can be discharged from the shock absorber 21 under the action of the pressure difference, thereby reducing the internal pressure of the shock absorber 21.

[0091] In another embodiment of the present application, the specific structure distribution of the shock absorber 21 is introduced. For example, the shock absorber 21 includes a first cylinder 213, a second cylinder 214, and a bottom valve; the first cylinder 213 is provided with a piston rod 2131, and the second cylinder 214 is sleeved outside the first cylinder 213; one end of the first cylinder 213 and one end of the second cylinder 214 are communicated through the bottom valve, and the other end of the first cylinder 213 is provided with an open end, and the size of the open end matches the size of the piston rod 2131; wherein the sensor 211 is arranged on the inner side wall of the second cylinder 214, and the second cylinder 214 is used for storing oil.

[0092] In a possible implementation, the shock absorber 21 can include a first cylinder 213 and a second cylinder 214 used for cooperating to achieve the damping effect. The first cylinder 213 is provided with a piston rod 2131, the second cylinder 214 is used for storing oil, and the first cylinder 213 and the second cylinder 214 can be communicated through a bottom valve.

[0093] For example, when the shock absorber 21 receives an external force, the piston rod 2131 can be telescoped under the action of the external force, while pushing the oil to flow between the first cylinder body 213 and the second cylinder body 214 through the bottom valve. It should be noted that when the oil flows between the first cylinder body 213 and the second cylinder body 214, the corresponding damping force is generated between the oil and the cylinder wall, thereby realizing the damping effect of the shock absorber 21.

[0094] For example, FIG. 6 is a structural schematic diagram of the damper inside the shock absorber 21 provided by the embodiment of the present application. As shown in FIG. 6, the damper can specifically include the piston rod 2131, a sealing check ring 601, an oil seal 602, the second cylinder body 214, a solenoid valve 603, a base valve 604, the control valve 212, a lower bushing 605, a bottom valve 606, the sensor 211, and a limiting ring 607.

[0095] It should be noted that the accommodating cavity in the top seat of the shock absorber 21 can specifically be used to accommodate part of the structure of the piston rod 2131 and the bushing sleeved outside the piston rod 2131; the area where the bottom valve 606 is located is also provided with a sealing structure; the control valve 212 can be arranged in the cavity of the second cylinder body 214 above the oil level, which is not specifically limited here.

[0096] In another embodiment of the present application, the specific structural distribution and specific implementation of the piston rod 2131 are also introduced. For example, as shown in FIG. 6, the piston rod 2131 is provided with the solenoid valve 603.

[0097] Specifically, the solenoid valve 603 is used to control the flow amount of the oil between the first cylinder body 213 and the second cylinder body 214 in response to the telescoping degree of the piston rod 2131.

[0098] In a possible implementation, the solenoid valve 603 can electrically control the flow amount of the oil between the first cylinder body 213 and the second cylinder body 214 during the telescoping movement of the piston rod 2131 according to the telescoping degree of the piston rod 2131, so that the size of the damping force value can be flexibly adjusted by controlling the different flow amounts of the oil.

[0099] In another embodiment of the present application, another structural distribution of the damping system 20 is also introduced. For example, the damping system 20 includes four shock absorbers 21, which are distributed in a central symmetric manner; wherein each shock absorber 21 is connected with the air supply machine 22 through one air charging pipeline.

[0100] In a possible implementation, FIG. 7 is another structural schematic diagram of the damping system 20 provided by the embodiment of the application. As shown in FIG. 7, the damping system 20 includes four dampers 21, an air supply machine 22, and an air tank 701. The damper 21, the air supply machine 22, and the air tank 701 are connected through air charging pipelines respectively, and the four dampers 21 are distributed in a central symmetry.

[0101] For example, FIG. 8 is a structural schematic diagram of the air tank 701 provided by the embodiment of the application. As shown in FIG. 8, the air tank 701 includes a cylinder body 801, a quick connector 802, and a mounting bracket 803. Specifically, the cylinder body 801 can be used to store compressed air provided by the air supply machine 22 to provide air pressure to the damper 21.

[0102] The embodiment of the application further provides a control method of the damping system 20. For example, FIG. 9 is a flowchart of the control method of the damping system 20 provided by the embodiment of the application. As shown in FIG. 9, the method includes the following steps.

[0103] In step 901, the air pressure state inside the damper 21 is acquired. The air pressure state includes low air pressure or high air pressure.

[0104] For example, the air pressure state inside the damper 21 can be monitored in real time by a sensor 211 inside the damper 21.

[0105] In step 902, it is determined whether the air pressure inside the damper 21 is abnormal according to the air pressure state. If the air pressure inside the damper 21 is abnormal, the air pressure inside the damper 21 is adjusted based on the air pressure state.

[0106] For example, when the sensor 211 monitors that the air pressure inside the damper 21 is in an abnormal state, an abnormal signal can be sent to a processing unit of the damping system 20, and the air supply machine 22 and the damper 21 of the damping system 20 are controlled by the processing unit to exchange air, so that the air pressure inside the damper 21 returns to a normal state.

[0107] The embodiment of the application further provides a vehicle 30, which can include the damping system 20 described above. For example, the damper 21 inside the damping system 20 can be installed inside the vehicle 30 through a fixing assembly 33. It should be noted that the processing unit of the damping system 20 described above can be a vehicle controller of the vehicle 30.
