[0002] The suspension is a crucial component connecting the vehicle body and wheels, its main function being to balance vehicle performance, ride comfort, and handling. There are various types of suspensions, such as mechanical spring suspensions and hydraulic suspensions. A hydraulic suspension is a system that adjusts suspension stiffness, damping, and vehicle height through changes in hydraulic oil pressure. Hydraulic suspensions utilize a hydraulic pump to generate pressure, which drives hydraulic cylinders or hydraulic shock absorbers, thereby controlling the vehicle chassis.

[0003] Since hydraulic suspension relies on the circulation of hydraulic oil to achieve its control functions, a hydraulic oil reservoir is installed to improve its reliability. This reservoir stores and replenishes hydraulic oil, and can accommodate oil expansion due to temperature increases, ensuring the high efficiency of the hydraulic system. Furthermore, to prevent gas generated during hydraulic oil circulation from affecting its stability, the reservoir is typically located at the highest point of the hydraulic suspension, allowing gas generated during circulation to quickly separate from the hydraulic oil and enter the reservoir.

[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0055] Before introducing the oil reservoir, oil reservoir assembly, suspension system, and vehicle provided in the embodiments of this application, the relevant technologies of this application will be introduced first.

[0056] In related technologies, the oil reservoir's inner cavity includes a first cavity for storing oil and a second cavity for mounting the oil pump, with the second cavity located at the bottom of the first cavity. When the vehicle's longitudinal axis (i.e., the axis parallel to the vehicle's forward direction) is parallel to or has a small angle with the horizontal plane, the oil in each area of ​​the first cavity can smoothly enter the second cavity under gravity, facilitating smooth oil intake for the oil pump. However, the hydraulic suspension oil reservoir operates under complex conditions, and suspension adjustments cause significant changes in the oil volume within the reservoir. When the reservoir's conformal design results in an irregular structure, and the vehicle's posture changes considerably, some areas of the first cavity cannot flow to the gear pump; that is, some areas of the first cavity become dead zones where oil does not flow to the oil pump. This leads to a lower effective volume of the reservoir, reducing its effective oil storage capacity. Consequently, the reservoir may be unable to provide sufficient oil to the suspension system, hindering the normal operation of the suspension system's adjustment function and reducing the system's reliability.

[0057] For example, when the second cavity is located at the bottom of the first cavity and near the rear of the vehicle, and the first cavity protrudes outward along the transverse axis of the vehicle (i.e., the axis parallel to the transverse axis connecting the vehicle's wheels) at one end near the front of the vehicle, when the slope of the road surface is large and the angle at which the front of the vehicle is raised is large, there is an oil dead zone in the area of ​​the first cavity near the front of the vehicle and at both ends along the transverse axis of the vehicle.

[0058] Based on this, embodiments of this application provide an oil reservoir, an oil reservoir assembly, a suspension system, and a vehicle. When the vehicle's posture changes significantly, a drainage structure can guide all the oil in the dead zone of the first chamber to the second chamber, thereby improving the volume utilization rate of the oil reservoir and increasing its effective oil storage capacity. This facilitates the normal operation of the vehicle's overall adjustment function of the hydraulic suspension, thus improving the reliability of the hydraulic suspension. In this way, the oil reservoir can meet the requirements of different operating conditions, especially the requirements under multi-slope conditions.

[0059] The following combination Figures 1 to 10 This application provides a detailed description of an oil reservoir 10, an oil reservoir assembly 100, a hydraulic suspension, and a vehicle, as provided in the embodiments of this application.

[0060] Please see Figures 1 to 5 According to a first aspect of this application, an oil reservoir 10 is provided. The oil reservoir 10 includes a reservoir shell 11 and a flow-through structure 12. The reservoir shell 11 has a first cavity 111 and a second cavity 112. The second cavity 112 communicates with the first cavity 111, and the first cavity 111 has an oil dead zone 113. The flow-through structure 12 connects the oil dead zone 113 and the second cavity 112. The second cavity 112 is configured to communicate with the oil inlet port of an oil pump 20.

[0061] In this application, the oil dead zone 113 refers to an area within the oil reservoir 10 where oil flow is hindered, making it difficult for the oil pump 20 to draw it away, especially when the vehicle's posture changes significantly. Therefore, the location of the oil dead zone 113 will vary depending on the shape of the oil reservoir 10, its installation location, and the type of vehicle. The specific location of the oil dead zone 113 can be determined based on the structure of the oil reservoir 10, its installation location, and the vehicle type.

[0062] Specifically, the bottom of the second cavity 112 is connected to the bottom of the first cavity 111 so as to facilitate the introduction of oil from the first cavity 111 into the second cavity 112 by gravity.

[0063] It can be understood that the port of the oil pump 20 is connected to the second chamber 112; therefore, the second chamber 112 can also be referred to as the pump's oil suction area. Specifically, at least a portion of the oil pump 20 is disposed within the second chamber 112. The drive motor of the oil pump 20 is mounted outside the housing 11.

[0064] It is understandable that, under normal driving conditions, the height of the oil dead zone 113 is not lower than the height of the second chamber 112, so that the oil in the oil dead zone 113 can flow to the second chamber 112 under the action of gravity.

[0065] It is understood that the drainage structure 12 can be a channel set on the inner wall of the first cavity 111, or it can be a pipe set on the outside of the pot shell 11. In practical applications, the specific structure of the drainage structure 12 can be selected according to the specific structure of the oil pot 10 and the surrounding environment of the installation location of the oil pot 10.

[0066] It can be understood that the drainage structure 12 utilizes the principle of communicating vessels, that is, the liquid levels in the containers connected at the lower end always remain level. In this way, the oil in the dead zone 113 can flow to the second chamber 112 through the drainage structure 12.

[0067] In this embodiment, by setting up a drainage structure 12, the oil in the dead zone 113 is directed to the second chamber 112. When the vehicle's posture changes significantly, the drainage structure 12 can guide all the oil in the dead zone 113 of the first chamber 111 to the second chamber 112, thereby improving the volume utilization rate of the oil reservoir 10 and increasing its effective oil storage capacity. This facilitates the normal operation of the hydraulic suspension's overall vehicle adjustment function and improves the reliability of the hydraulic suspension. In this way, the oil reservoir 10 can meet the requirements of different operating conditions, especially the requirements under multi-slope conditions.

[0068] Please see Figure 4 In some embodiments, the drainage structure 12 is connected to the bottom of the oil dead zone 113. In this way, regardless of the oil level in the dead zone, the oil can flow naturally to the second chamber 112 located below it by gravity, which helps to improve the volume utilization rate of the oil container 10, thereby increasing the effective oil storage capacity of the oil container 10.

[0069] Please see Figure 1 or Figure 5 In some embodiments, at least a portion of the drainage structure 12 is bent. Thus, when the drainage structure 12 guides the flow of oil, the bending portion of the drainage structure 12 can change the flow direction of the oil within the drainage structure 12, thereby consuming the kinetic energy of the oil flow and reducing the velocity of the oil flowing out of the drainage structure 12, preventing the oil from directly impacting the second inner cavity and reducing turbulence.

[0070] Please see Figure 5 In some embodiments, the second cavity 112 is configured to be located at one end of the first cavity 111 near the front or rear of the vehicle.

[0071] It is understandable that the vehicle's operating conditions mainly involve leveling, climbing, and descending. The presence of a dead zone 113 in the oil reservoir 10 mainly occurs when the vehicle is climbing or descending.

[0072] Based on this, in this embodiment, by means of the above-mentioned settings, in either the uphill or downhill working conditions, the oil in the first chamber 111 on the longitudinal axis and near the second chamber 112 can flow directly into the second chamber 112, thereby reducing the number of dead zones 113 in the oil reservoir 10 and simplifying the structure of the oil reservoir 10.

[0073] Please see Figure 5 In some embodiments, the second cavity 112 is configured to be located at one end of the first cavity 111 near the rear of the vehicle.

[0074] It is understandable that when the vehicle accelerates and climbs a hill, most of the oil in the first chamber 111 will gather towards the rear of the vehicle due to inertia, so that more oil in the first chamber 111 can enter the second chamber 112, fully covering the port of the oil pump 20 connected to the second chamber 112 with oil, thereby facilitating the oil pump 20 to draw oil from the oil reservoir 10 and deliver it to the suspension system, thus improving the reliability of the suspension system.

[0075] In addition, the oil pump 20 is a component with a certain weight. With the above arrangement, the oil pump 20 can be placed at the end of the fuel tank near the rear of the vehicle to appropriately increase the rear weight distribution and improve the front and rear axle load distribution. For front-engine vehicles, the front of the vehicle itself is relatively heavy, and the increase in rear weight distribution can improve the rear wheel grip when driving at high speeds or turning, indirectly enhancing vehicle stability.

[0076] Please see Figures 1 to 7 In some embodiments, the drainage structure 12 includes a pipe 121. The pipe 121 is disposed on the outside of the reservoir shell 11. The end of the pipe 121 is connected to the reservoir shell 11. A first through hole 114 is provided at the location of the reservoir shell 11 opposite to the oil dead zone 113 and the second cavity 112. The two ends of the internal channel of the pipe 121 are respectively connected to a first through hole 114.

[0077] It can be understood that the two ends of the internal channel of the pipe fitting 121 are respectively connected to a first through hole 114 to connect the oil in the oil dead zone 113 and the oil in the second cavity 112, thereby realizing the drainage by using the principle of communicating vessels. That is, the liquid levels in the oil dead zone 113 and the second oil cavity are always kept at the same level, so as to drain the oil in the oil dead zone 113 to the second cavity 112.

[0078] It is understandable that fitting 121 diverts the oil in the dead zone 113 to the second chamber 112 that encloses the gear pump.

[0079] In addition, the inner diameter of pipe fitting 121 and the diameter of the first through hole 114 can be designed according to parameters such as the flow rate of oil pump 20.

[0080] Among them, the pipe fitting 121 is an external drainage device, and its arrangement is not affected by the internal structure of the oil can 10. The pipe fitting 121 can be flexibly arranged in the parts that need to be connected, so as to improve the manufacturability of the oil can 10.

[0081] Please see Figure 6 and Figure 7 In some embodiments, a pipe connector 13 is provided between the end of the pipe fitting 121 and the container shell 11. One end of the pipe connector 13 is connected to the container shell 11, and the other end is inserted into the pipe fitting 121. The internal channel of the pipe fitting 121 communicates with the adjacent first through hole 114 through the internal channel of the pipe connector 13. In this way, the ease of connection between the pipe fitting 121 and the container shell 11 can be improved by using the pipe connector 13, thereby improving the assembly efficiency of the oil container 10.

[0082] It is understood that the pipe joint 13 and pipe fitting 121 can be set with the required area according to the actual situation of the vehicle, so as to meet the usage needs of different vehicles under different working conditions.

[0083] Please see Figure 6 and Figure 7 In some embodiments, the drainage structure 12 further includes a pipe connector 14. The pipe connector 14 is circumferentially disposed at the insertion point of the pipe fitting 121 and the pipe joint 13, so that the end of the pipe fitting 121 grips the pipe joint 13. This improves the reliability and sealing of the connection between the pipe fitting 121 and the pipe joint 13.

[0084] For example, the pipe connector 14 can be a clamp, a clamp, a cable tie, or other components.

[0085] Please see Figure 6 and Figure 7 In some embodiments, an anti-detachment structure 131 is provided on the outer peripheral surface of the pipe fitting 13. The anti-detachment structure 131 is located at the end of the pipe connector 14 facing away from the kettle shell 11. In this way, the anti-detachment structure 131 can prevent the pipe connector 14 from falling off the pipe fitting 13, thereby improving the firmness of the connection between the pipe fitting 121 and the pipe fitting 13.

[0086] Please see Figure 6 and Figure 7 In some embodiments, the outer circumferential surface of the pipe fitting 13 smoothly transitions to the surface of the anti-detachment structure 131 away from the pipe fitting 13. This arc-shaped transition structure between the outer circumferential surface of the pipe fitting 13 and the surface of the anti-detachment structure 131 away from the pipe fitting 13 improves guidance during the docking of the pipe fitting 121 and the pipe fitting 13, thus enhancing the ease of docking. Furthermore, this arc-shaped transition structure avoids stress concentration, thereby improving the stress state of the pipe fitting 13.

[0087] Please see Figure 6 and Figure 7 In some embodiments, the anti-detachment structure 131 is integrally formed with the pipe connector 13. This improves the reliability of the connection between the anti-detachment structure 131 and the pipe connector 13.

[0088] In some embodiments, the pipe connector 14 is an elastic ring clamp. The elastic ring clamp is a ring-shaped fastening component with elastic deformation capability, primarily made of rubber, elastic plastic, metal spring sheets, or composite materials. The elastic ring clamp applies continuous and uniform pressure to the clamped pipe joint 13 and pipe fitting 121 through its own elastic tension, achieving relative fixation of the pipe joint 13 and pipe fitting 121 and sealing of the mating parts between them, while maintaining a reliable fastening effect.

[0089] In some embodiments, fitting 121 is a rubber hose. Fitting 121 is sleeved on pipe connector 13 and is interference-fitted with pipe connector 13. In this way, the elastic deformation performance of the rubber hose can increase the fitting pressure between fitting 121 and pipe connector 13, thereby improving the sealing performance between fitting 121 and pipe connector 13. At the same time, the flexibility and bending performance of the rubber hose can allow fitting 121 to deform with vehicle operation, thereby effectively avoiding fatigue fracture or loosening of the connector caused by bending or pulling of fitting 121.

[0090] Specifically, the fitting 121 of the rubber hose is fixed to the pipe joint 13 by an elastic ring clamp, so as to realize the connection between the fitting 121 and the pipe joint 13 and ensure the sealing between the fitting 121 and the pipe joint 13.

[0091] Please see Figure 5 In some embodiments, a portion of the first cavity 111 protrudes outward to form a convex cavity 115. The convex cavity 115 has an oil dead zone 113. The end of the pipe 121 away from the second cavity 112 communicates with the convex cavity 115. In this way, by solving the oil flow problem within the oil dead zone 113 through the pipe 121, the available space on the vehicle can be effectively utilized to increase the volume of the oil reservoir 10, thereby increasing the oil storage capacity of the oil reservoir 10.

[0092] Please see Figure 3 and Figure 5 In some embodiments, the second cavity 112 is connected to the bottom of the first cavity 111. The drainage structure 12 includes a guide groove 122. The guide groove 122 extends along the bottom wall of the first cavity 111 to connect the oil dead zone 113 and the second cavity 112. Thus, by providing the guide groove 122 on the inner wall of the housing 11, the drainage structure 12 has a simple structure and smooth flow, thereby effectively guiding the oil in the oil dead zone 113 to the second cavity 112 that encloses the oil pump 20.

[0093] It is understandable that the partially flexible design of the flow channel 122 allows the flow path of the flow channel 122 to be curved, thereby enabling the liquid to flow smoothly and reducing turbulence.

[0094] The path by which the guide channel 122 directs the oil in the oil dead zone 113 to the second chamber 112 can be exemplarily seen. Figure 3 and Figure 5 As shown by the dashed line with the arrow in the middle.

[0095] It is understandable that the guide groove 122 simplifies the structure of the flow-guiding structure 12, so that the oil dead zone 113 and the second cavity 112 can be connected without a complex structure. Moreover, the guide groove 122 can be formed synchronously with the pot shell 11, which is convenient for manufacturing and maintenance.

[0096] Please see Figure 7In some embodiments, an oil filter component 15 is provided at least at one end of the drainage structure 12.

[0097] Specifically, an oil filter component 15 is provided at one end of the flow-guiding structure 12 near the oil dead zone 113 to filter impurities in the oil and prevent impurities from entering the flow-guiding structure 12.

[0098] For example, the oil filtration component 15 is a filter screen.

[0099] It is understood that the oil dead zone 113 is more prone to accumulating impurities compared to other areas of the first chamber 111. Therefore, this embodiment provides an oil filter component 15, which can effectively reduce the amount of impurities in the first chamber 111 entering the suspension system, thereby improving the reliability of the suspension system.

[0100] Please see Figure 6 In some embodiments, an oil splash guard 16 is provided at the oil outlet end of the drainage structure 12 to prevent oil from splashing when it is discharged from the drainage structure 12. In this way, the velocity of the oil flowing out of the drainage structure 12 can be reduced to prevent the oil from directly impacting the second inner cavity and reduce turbulence.

[0101] Specifically, the oil splash prevention component 16 is provided at one end of the drainage structure 12 near the second cavity 112.

[0102] For example, the oil splash prevention component 16 is an oil baffle.

[0103] Please see Figure 3 and Figure 5 In some embodiments, the oil container 10 further includes a plate 17. The plate 17 is disposed in the first cavity 111. At least a portion of the edge of the plate 17 is connected to the inner wall of the first cavity 111. In this way, the structural strength of the oil container 10 can be improved by the plate 17, which is beneficial to the impact resistance of the oil container 10, etc.

[0104] For example, the kettle shell 11 is made of plastic, specifically PP plastic, and the kettle shell 11 is integrally formed with the plate 17.

[0105] Please see Figure 3 and Figure 5 In some embodiments, a second through hole 171 is provided on the plate 17. The second through hole 171 connects the regions of the first cavity 111 located on both sides of the plate 17 to balance the air pressure in the regions of the first cavity 111 located on both sides of the plate 17.

[0106] The second through hole 171 can connect the upper part of the liquid surface of the multiple small oil chambers separated by the plate 17 in the first cavity 111, so as to ensure the breathability of the oil reservoir 10 and make the pressure in all parts of the first cavity 111 consistent. This can not only make the liquid surface in the dead zone 113 and the liquid surface in the second cavity 112 coplanar, but also avoid excessive pressure on local seals, thereby improving the sealing performance.

[0107] In addition, when a venting structure is designed at the top of the oil reservoir 10, the air chamber above the oil dead zone 113 is connected to the venting structure through the second through hole 171 of the reservoir, so as to communicate with the outside atmosphere through the venting structure. This ensures that the oil dead zone 113 can normally flow through the drainage structure 12 to the second chamber 112 surrounding the oil pump 20 for oil supply.

[0108] The guide channel 122 is designed to be installed on the bottom wall of the first cavity 111, and the guide channel 122 can connect different chambers of the first cavity 111 that are separated by baffles.

[0109] Please see Figure 3 and Figure 5 In some embodiments, the housing 11 also has a mounting port 116. The mounting port 116 communicates with the second chamber 112. The mounting port 116 is configured to mount the oil pump 20. It is understood that the oil pump 20 delivers oil from the second chamber 112 into the hydraulic lines of the suspension system through the mounting port 116, or delivers oil from the hydraulic lines into the second chamber 112.

[0110] Please see Figure 3 and Figure 8 In some embodiments, the portion of the reservoir shell 11 near the mounting opening 116 protrudes into the second cavity 112 to form a protrusion 117 in the second cavity 112, and a mounting groove 118 is formed on the outside of the reservoir shell 11. This allows the motor of the oil pump 20 to be mounted within the mounting groove 118, improving the compactness of the connection between the oil reservoir 10, the oil pump 20, and the motor, thereby reducing the overall space occupied by the structure and simplifying the layout.

[0111] Please see Figure 5 In some embodiments, reinforcing ribs 119 are provided on the inner wall of the first cavity 111. This can improve the structural strength of the oil container 10, thereby enhancing its impact resistance.

[0112] Please see Figure 9 and Figure 10 According to a second aspect of this application, an oil dispenser assembly 100 is provided. The oil dispenser assembly 100 includes the aforementioned oil dispenser 10.

[0113] It is understood that the oil dispenser assembly 100 includes the oil dispenser 10 described above, and the oil dispenser assembly 100 has all the beneficial effects of the oil dispenser 10 described above, which will not be repeated here.

[0114] Please see Figure 9 In some embodiments, the oil container assembly 100 further includes a sub-oil container 21 and a first tube 22. The sub-oil container 21 is located above the oil container 10. The sub-oil container 21 is connected to the first cavity 111 via the first tube 22. Thus, when the space on the chassis for arranging the oil container 10 is limited, the volume of the oil container 10 can be reduced, and the sub-oil container 21 can be configured to ensure the overall oil storage capacity of the oil container assembly 100, thereby reducing the difficulty of arranging the oil container 10.

[0115] Please see Figure 9 In some embodiments, the oil can assembly 100 further includes a second tube 23, one end of which is connected to the sub-oil can 21 and the other end is connected to the top of the first cavity 111.

[0116] It is understandable that the oil reservoir 21 is equipped with a breather valve 24.

[0117] Thus, when the oil level in the reservoir 10 changes and the first pipe 22 is full of oil, the gas above the liquid surface in the reservoir 10 can be connected to the sub-reservoir 21 via the second pipe 23. This allows the gas pressure in the reservoir 10 and the sub-reservoir 21 to be balanced through the second pipe 23 and the breather valve 24, preventing excessive positive or negative pressure above the liquid surface in the reservoir 10. This facilitates smooth oil intake and drainage in the reservoir 10, ensuring the working efficiency of the oil pump 20, improving the hydraulic suspension adjustment rate, and enabling the normal operation of the overall vehicle adjustment function of the hydraulic suspension, thereby enhancing the reliability of the hydraulic suspension.

[0118] According to a third aspect of this application, a suspension system is provided, the suspension system including the aforementioned oil reservoir 10 or the aforementioned oil reservoir assembly 100.

[0119] It is understood that the suspension system includes the aforementioned oil reservoir 10, and the suspension system has all the beneficial effects of the aforementioned oil reservoir 10, which will not be repeated here.

[0120] According to a fourth aspect of this application, a vehicle is provided that includes the aforementioned suspension system.

[0121] It is understood that the vehicle includes the aforementioned oil can 10 and has all the beneficial effects of the aforementioned oil can 10, which will not be repeated here.

[0122] It is understood that the vehicle may be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this disclosure does not make any specific restrictions.
