DETAILED DESCRIPTION

[0045] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0046] It should be pointed out that the embodiments of the present invention and the technical features therein may be combined with each other without conflict.

[0047] In addition, the "first" and "second" involved in the embodiments of the present invention are used to distinguish features of different scopes or purposes, and are not intended to limit the number or order of features. For example, the first sliding valve 212 refers to a sliding valve that matches the support portion 211 having a fluid receiving cavity; the second sliding valve 215 refers to a sliding valve that matches the hollow structure support portion 214 having an annular liquid receiving cavity.

[0048] The vehicle involved in the embodiment of the present invention may be an internal combustion engine vehicle using an engine as a power source, a hybrid vehicle using an engine and an electric motor as a power source, an electric vehicle using an electric motor as a power source, or the like.

[0049] Specifically, an embodiment of the present invention provides a vehicle suspension. Figures 1 to 4 As shown, the vehicle suspension may include: a coil spring 10 and a fluid regulating structure 20, wherein:

[0050] The fluid regulating structure 20 may include an adjustable sealed chamber 21;

[0051] The adjustable sealing chamber 21 is disposed at the upper end of the coil spring 10 and is at least partially embedded in the coil spring 10;

[0052] The adjustable sealing chamber 21 is used to receive input fluid or discharge the fluid therein.

[0053] Among them, the coil spring 10 mainly provides a buffering effect for the vehicle body or the vehicle chassis by virtue of its own elasticity. During the driving process of the vehicle, the coil spring 10 can effectively prevent the vehicle body or the vehicle chassis from shaking and bumping, thereby improving the comfort of the passengers and the driver when riding in the vehicle.

[0054] The fluid input into the adjustable sealing chamber 21 may be air, liquid, etc.

[0055] It is worth noting that, due to the sealing performance of the adjustable sealing chamber 21, after the fluid enters the adjustable sealing chamber 21, the space of the adjustable sealing chamber 21 becomes larger, that is, the size of the adjustable sealing chamber 21 is increased. Furthermore, since the adjustable sealing chamber 21 is disposed at the upper end of the coil spring 10, the adjustable sealing chamber 21 can directly act on the vehicle body or the vehicle chassis, thereby lifting the vehicle body and the vehicle chassis.

[0056] In addition, since the adjustable sealing chamber 21 is arranged at the upper end of the coil spring 10, it does not need to overcome the elastic force of the coil spring 10, so that the force required to overcome to adjust the height of the vehicle body or the vehicle chassis is only the gravity of the vehicle body and the vehicle chassis, so that the height of the vehicle body or the vehicle chassis can be adjusted more conveniently.

[0057] Furthermore, since the adjustable sealing cavity 21 is at least partially embedded in the coil spring 10, the adjustable sealing cavity 21 can guide the deformation direction of the coil spring 10 to prevent the vehicle body or chassis from shaking, thereby further improving the stability of the vehicle body or chassis.

[0058] against Figure 1 or Figure 2 The provided vehicle suspension is provided with a fluid regulating structure including an adjustable sealed cavity. By controlling the fluid input into the adjustable sealed cavity or extracting the fluid in the adjustable sealed cavity, the size of the adjustable sealed cavity can be dynamically adjusted according to user needs, thereby realizing dynamic control of the height of the vehicle suspension. The height of the vehicle suspension determines the height of the vehicle body or chassis relative to the ground or the wheels. Therefore, the vehicle suspension provided by the embodiment of the present invention has relatively high controllability.

[0059] Furthermore, if Figures 1 to 4 As shown, in addition to the adjustable sealing chamber 21, the fluid regulating structure 20 may further include: a switch valve 22 and a pressure regulator 23, wherein:

[0060] The pressure regulator 23 and the adjustable sealed chamber 21 are connected through a pipeline, and are used to pump the fluid into the adjustable sealed chamber 21 through the pipeline or to suck the fluid in the adjustable sealed chamber 21;

[0061] The switch valve 22 is arranged on the pipeline, and is used to control the connection or disconnection between the pressure regulator 23 and the adjustable sealing chamber 21 .

[0062] The switch valve 22 can be opened or closed mechanically or electrically. When the switch valve 22 is opened, the pipeline between the pressure regulator 23 and the adjustable sealed chamber 21 is connected; when the switch valve 22 is closed, the pipeline between the pressure regulator 23 and the adjustable sealed chamber 21 is disconnected.

[0063] When the switch valve 22 is open, by applying pressure to the pressure regulator 23, the fluid in the pressure regulator 23 can enter the adjustable sealed chamber 21 through the pipeline, thereby increasing the space for the adjustable sealed chamber 21 to accommodate the fluid and increasing the height of the vehicle body or chassis. In addition, by reducing the pressure of the pressure regulator 23, the fluid in the adjustable sealed chamber 21 can be returned to the pressure regulator 23 through the pipeline, thereby reducing the space of the adjustable sealed chamber 21 and lowering the height of the vehicle body or chassis.

[0064] It is worth noting that the pressure of the pressure regulator 23 can be regulated mechanically or electrically.

[0065] By cooperating with the switch valve 22 and the pressure regulator 23, the height of the vehicle body or the chassis can be adjusted according to user needs to ensure the effectiveness of the adjustment.

[0066] Furthermore, the fluid is transported to the adjustable sealed cavity 21 through a pipeline, and the diameter of the pipeline is much smaller than the width or diameter of the adjustable sealed cavity 21, so that the height of the vehicle body or chassis can be raised more smoothly, thereby improving the driving stability of the vehicle and the riding comfort of the occupants or the driver.

[0067] There are two structures for the adjustable sealing chamber 21 .

[0068] Specifically, Figure 1 and Figure 2 As shown, the first structure of the adjustable sealing chamber 21 may include: a support portion 211 having a fluid receiving chamber and a first sliding valve 212, wherein:

[0069] The first sliding valve 212 is embedded in the fluid receiving chamber and is sealingly and slidingly connected to the inner wall of the fluid receiving chamber;

[0070] The fluid receiving chamber receives the input fluid, causing the first sliding valve 212 to move upward;

[0071] When the fluid containing chamber discharges the fluid therein, the first sliding valve 212 moves downward.

[0072] The first sliding valve 212 moves upward, driving the vehicle body or the vehicle chassis to move upward; the first sliding valve 212 moves downward, driving the vehicle body or the vehicle chassis to move downward.

[0073] The support portion 211 having the fluid receiving cavity can effectively improve the stability of the vehicle body or chassis.

[0074] For the first structure of the adjustable sealing chamber 21, as Figure 1 and Figure 2As shown, the outer side wall of the first sliding valve 212 and the inner side wall of the side wall of the fluid containing chamber are sealed by a sealing ring, so as to achieve the purpose of sealing the fluid containing chamber.

[0075] Further, for the first structure of the adjustable sealing chamber 21, as Figure 1 As shown, the pipeline connection port of the adjustable sealing chamber 21 is arranged at the top of the first sliding valve 212. In addition, Figure 2 As shown, the pipeline connection port of the adjustable sealing chamber 21 is arranged on the side of the first sliding valve 212. In addition, the pipeline connection port can also be arranged on the side of the supporting portion 211. The pipeline setting is flexible to meet the needs of different vehicle models.

[0076] Furthermore, if Figure 1 and Figure 2 As shown, for the first structure of the adjustable sealing chamber 21, the adjustable sealing chamber 21 may further include: an extension fixing area 213 disposed at the upper end of the support portion 211 and along the circumference of the support portion 211; the coil spring 10 is fixed to the extension fixing area 213 to ensure the stability of the coil spring 10.

[0077] Furthermore, if Figure 1 and Figure 2 As shown, for the first structure of the adjustable sealing cavity 21, the vehicle suspension may further include: a base 30 disposed at the lower end of the coil spring 10, wherein the base 30 is mounted on the axle or wheel; and the upper end of the adjustable sealing cavity 21 is mounted on the vehicle chassis. It is convenient to fix the coil spring 10 of the vehicle suspension with the base 30, thereby improving the stability of the vehicle suspension.

[0078] Among them, Figure 1 and Figure 2 As shown, for the first structure of the adjustable sealing cavity 21, the first sliding valve 212 included therein can be an n-type structure or an n-type deformation structure to ensure that the first sliding valve 212 is stably connected to the support portion 211 having the fluid containing cavity, thereby further improving the stability of the vehicle suspension operation.

[0079] Preferably, the above Figure 1 and Figure 2 The vehicle suspension of the first structure including the adjustable sealing chamber 21 is applied between the rear wheels of the vehicle and the chassis of the vehicle.

[0080] Specifically, Figure 3 and Figure 4 As shown, for the second structure of the adjustable sealing chamber 21, the vehicle suspension may further include: a damping device 40, wherein:

[0081] The coil spring 10 is nested on the damping device 40;

[0082] The pressure rod 41 of the damping device 40 penetrates the adjustable sealing chamber 21;

[0083] The lower end of the coil spring 10 is fixed to the outer side wall of the damping cavity 42 of the damping device 40;

[0084] The upper end of the coil spring 10 is fixed on the adjustable sealing chamber 21 .

[0085] The damping device 40 can further improve the stability of the elastic deformation of the coil spring 10 to reduce the vibration and shaking of the vehicle.

[0086] Furthermore, if Figure 3 and Figure 4 As shown, the second structure for the adjustable sealing cavity 21 may include a hollow structural support portion 214 having an annular liquid receiving cavity and a second sliding valve 215 with a top opening, wherein the second sliding valve 215 is embedded in the hollow structural support portion 214 and is sealed and slidably connected with the hollow structural support portion 214; the pressure rod 41 of the damping device 40 penetrates the hollow part of the hollow structural support portion 214 and the top opening of the second sliding valve 215. By matching the damping device 40 with the hollow structural support portion 214 having an annular liquid receiving cavity, the deformation direction of the coil spring 10 can be better controlled to prevent the coil spring 10 from shaking, thereby further improving the stability of vehicle operation.

[0087] Among them, Figure 3 and Figure 4 As shown, for the second structure of the adjustable sealing cavity 21, the second sliding valve 215 included therein is an n-type structure or an n-type deformation structure to ensure that the second sliding valve 215 is stably connected to the hollow structure support portion 214, further improving the stability of the vehicle suspension operation.

[0088] The outer wall of the second sliding valve 215 and the inner wall of the annular liquid containing chamber are sealed by a sealing ring; the side wall of the second sliding valve 215 is provided with a pipeline connection port for connecting with a pipeline, so as to further improve the sealing performance of the annular liquid containing chamber.

[0089] Further, for the second structure of the adjustable sealing chamber 21, as Figure 3 and Figure 4 As shown, the pipeline connection port of the adjustable sealing chamber 21 is arranged on the side of the first sliding valve 212. In addition, the pipeline connection port can also be arranged on the side of the hollow structure support portion 214. The pipeline setting is flexible to meet the needs of different models.

[0090] Preferably, for Figure 3 and Figure 4 The vehicle suspension of the second structure with the adjustable sealed chamber 21 is applied between the front wheels of the vehicle and the chassis of the vehicle.

[0091] Furthermore, if Figure 3 and Figure 4 As shown, for the second structure of the adjustable sealing chamber 21, the adjustable sealing chamber 21 may further include: an extension fixing area 213 arranged at the upper end of the hollow structure support portion 214 and along the circumference of the hollow structure support portion 214; the coil spring 10 is fixed to the extension fixing area 213 to ensure the stability of the coil spring 10.

[0092] Among them, the vehicle suspension provided by the above-mentioned embodiments can be arranged on the vehicle, and the various vehicle suspensions arranged on the vehicle can be uniformly regulated or independently regulated to meet different structural requirements.

[0093] Furthermore, based on the system architecture on which the vehicle suspension provided by the embodiment of the present invention relies, the technical scenarios to which the technical solutions provided by the embodiment of the present invention are applicable are explained.

[0094] Figure 5 An exemplary system architecture 500 is shown upon which a vehicle suspension may be applied.

[0095] like Figure 5 As shown, the vehicle system architecture 500 may include various systems, such as a driving control system 501, a power system 502, a sensor system 503, a control system 504, a vehicle suspension system 505, one or more peripheral devices 506, a power supply 507, a computer system 508, and a user interface 509, wherein the regulation of the vehicle suspension system 505 provided in the embodiment of the present invention may be achieved by interacting with the above-mentioned various systems. Optionally, the vehicle system architecture 500 may include more or fewer systems, and each system may include multiple elements. In addition, each system and element of the vehicle system architecture 500 may be interconnected by wire or wirelessly.

[0096] The vehicle system architecture 500 includes a driving control system 501, which can be in a fully or partially automated driving mode. For example, the driving control system 501 can adjust the vehicle suspension system 505 through electrical signals to change the height of the vehicle body or chassis without human interaction.

[0097] The power system 502 may include components that provide power movement for the vehicle. For example, the power system 502 may include an engine, an energy source, a transmission, wheels, tires, etc. Among them, the engine may be an internal combustion engine, an electric motor, an air compression engine, or a combination of other types of engines, such as a hybrid engine consisting of a gas-oil engine and an electric motor, and a hybrid engine consisting of an internal combustion engine and an air compression engine. The engine converts the energy source into mechanical energy and provides it to the transmission. Examples of energy sources may include gasoline, diesel, other petroleum-based fuels, propane, other compressed gas-based fuels, ethanol, solar panels, batteries, and other sources of electricity. The energy source may also provide energy for other systems of the vehicle. In addition, the transmission may include a gearbox, a differential, a drive shaft, a clutch, etc.

[0098] The sensor system 503 may include sensors for sensing the surrounding environment of the vehicle (such as sensors for sensing whether there are obstacles around) and pressure sensors for sensing whether there are passengers in the seats. For example, a positioning system (the positioning system may be a global positioning system (GPS) system, or a Beidou system or other positioning systems), a radar, a laser rangefinder, an inertial measurement unit (IMU), a camera, and a capacitive sensor. The positioning system can be used to locate the geographic location of the vehicle. The IMU is used to sense the position and orientation changes of the vehicle based on inertial acceleration. In one embodiment, the IMU may be a combination of an accelerometer and a gyroscope. The radar may use radio signals to sense objects in the surrounding environment of the vehicle. In some embodiments, in addition to sensing objects, the radar may also be used to sense the speed and / or direction of travel of the object.

[0099] In order to detect environmental information, objects, etc. outside the vehicle, a camera or the like may be configured at an appropriate location outside the vehicle. For example, in order to obtain an environmental image of the side of the vehicle, the camera may be on a rearview mirror on the side of the vehicle. The camera may be a static or video camera.

[0100] The control system 504 may include a software system for implementing vehicle driving control, such as a system for analyzing the vehicle's surrounding environment, a system for route planning, a system for avoiding obstacles, a visual system for image analysis, etc. The control system 504 may also include hardware systems such as a throttle, a steering wheel system, a seat belt system, an airbag system, peripheral equipment (such as a projection device, a display, etc.), and a vehicle suspension control. In addition, the control system 504 may include components other than those shown and described in addition or in an alternative manner. Alternatively, some of the components shown above may be reduced.

[0101] Furthermore, as described above, the control system 504 can further implement a part of regulating the vehicle suspension, receive a control signal for the vehicle suspension input by a user, and use the control signal to drive the switch valve and pressure regulator of the vehicle suspension.

[0102] In addition, the control system 504 may also interact with external sensors, other autonomous driving devices, other computer systems, or users through the peripheral devices 506. The peripheral devices 506 may include wireless communication systems, onboard computers, microphones and / or speakers, cameras, and projectors.

[0103] After receiving the trigger, the vehicle suspension system 505 controls the switch valve and the pressure regulator in the vehicle suspension system 505 to change the space size of the adjustable sealed cavity included therein, thereby changing the height of the vehicle body or the vehicle chassis. In addition, the vehicle suspension system 505 interacts with the control system 504 to provide the control system 504 with a trigger signal of the vehicle suspension, so that the control system 504 changes the space of the adjustable sealed cavity 21 based on the trigger signal of the vehicle suspension.

[0104] In some embodiments, peripherals 506 provide a means for a user of control system 504 to interact with a user interface. For example, an onboard computer can provide information to a user of the vehicle. The user interface can also operate the onboard computer to receive input from the user. The onboard computer can be operated via a touch screen. In other cases, peripherals can provide a means for communicating with other devices located in the vehicle. For example, a microphone can receive audio (e.g., voice commands or other audio input) from a user of control system 504. Similarly, a speaker can output audio to a user of control system 504.

[0105] The wireless communication system can communicate with one or more devices wirelessly directly or via a communication network. For example, the wireless communication system can communicate with a network such as a cellular network, WiFi, and a wireless local area network (WLAN), or can communicate directly with a device using an infrared link, Bluetooth, or ZigBee. Other wireless protocols, such as various autonomous driving communication systems, etc.

[0106] The power source 507 can provide power to various components of the vehicle. The power source 507 can be a rechargeable lithium-ion or lead-acid battery.

[0107] The functions of implementing vehicle suspension control are controlled by computer system 508. Computer system 508 may include at least one processor that executes instructions stored in a non-transitory computer-readable medium such as a memory. Computer system 508 provides the above control system with execution code for controlling vehicle suspension.

[0108] The processor can be any conventional processor, such as a commercially available central processing unit (CPU). Alternatively, the processor can be a dedicated device such as an application specific integrated circuit (ASIC) or other hardware-based processor. Those of ordinary skill in the art will appreciate that the processor, computer, or memory can actually include multiple processors, computers, or memories that may or may not be stored in the same physical housing. For example, the memory can be a hard disk drive or other storage media that is located in a housing different from the computer. Therefore, references to processors or computers will be understood to include references to a collection of processors or computers or memories that may or may not operate in parallel. Different from using a single processor to perform the steps described herein, some components such as steering components and deceleration components can each have their own processors that only perform calculations related to the functions specific to the components.

[0109] The user interface 509 is used to provide information to or receive information from a user of the vehicle. Optionally, the user interface 509 may include one or more input / output devices within the set of peripheral devices 506, such as a wireless communication system, an onboard computer, a microphone, and a speaker.

[0110] It should be understood that the above components are only examples. In actual applications, the components in the above modules or systems may be added or deleted according to actual needs. Figure 5 It should not be understood as limiting the embodiments of the present application.

[0111] Furthermore, an embodiment of the present invention also provides an electronic device. The electronic device may include:

[0112] one or more processors;

[0113] a storage device for storing one or more programs,

[0114] When the one or more programs are executed by the one or more processors, the one or more processors implement the method for regulating vehicle suspension provided in the above embodiment.

[0115] Furthermore, an embodiment of the present invention also provides a computer-readable medium on which a computer program for implementing the method for regulating a vehicle suspension is stored.

[0116] When the computer program is executed by an onboard processor, a method for regulating a vehicle suspension is implemented.

[0117] As another aspect, the present invention also provides a computer-readable medium, which may be included in the device described in the above embodiment; or may exist independently without being assembled into the device. The above computer-readable medium carries one or more programs, and when the above one or more programs are executed by a device, the device includes: providing a driving signal to the switch valve and pressure regulator of the vehicle suspension, and controlling the switch valve and pressure regulator to open by the driving signal to input fluid into the adjustable sealed cavity of the vehicle suspension, so that the space of the adjustable sealed cavity is increased, thereby raising the height of the vehicle body and the chassis; in addition, the switch valve and pressure regulator can also be controlled to open by another driving signal to extract the fluid in the adjustable sealed cavity of the vehicle suspension, so that the space of the adjustable sealed cavity becomes smaller, thereby reducing the height of the vehicle body and the chassis.

[0118] According to the vehicle suspension of the embodiment of the present invention, a fluid regulating structure including an adjustable sealed cavity is provided. By controlling the fluid input into the adjustable sealed cavity or extracting the fluid in the adjustable sealed cavity, the size of the adjustable sealed cavity can be dynamically adjusted according to user needs, thereby realizing dynamic control of the height of the vehicle suspension. The height of the vehicle suspension determines the height of the vehicle body or chassis relative to the ground or the wheels. Therefore, the vehicle suspension provided by the embodiment of the present invention has relatively high controllability.

[0119] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may occur depending on design requirements and other factors.
