To store these liquids, cars are equipped with numerous storage containers, such as fuel tanks, windshield washer fluid tanks, and coolant tanks. During vehicle operation, road bumps and frequent acceleration and braking cause the liquids within these containers to break their static state, constantly shaking and fluctuating. The energy generating this shaking and fluctuation originates from the vehicle itself, resulting in energy waste. Furthermore, the sloshing of the liquids within the containers produces noise, affecting the driving and passenger experience.

[0038] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0040] Vehicles have various liquid containers. When a vehicle travels on bumpy roads, accelerates rapidly, or decelerates suddenly, the liquid levels in these containers change, and the liquid may experience impacts. During this process, there is a loss of kinetic and potential energy in the liquid. Because there are liquid containers in different locations on the vehicle, the overall energy loss is significant.

[0041] The main types of liquid containers commonly found on vehicles include the following:

[0042] Fuel tank: Stores fuel used by the vehicle, such as gasoline, diesel, or alternative fuels.

[0043] Engine oil container: In some vehicle designs, engine oil may be stored in a separate container, although most vehicles have an integrated oil pan inside the engine to store engine oil.

[0044] Coolant (antifreeze) tank: also known as a radiator or expansion tank, it stores the coolant used in the engine cooling system.

[0045] Brake fluid reservoir: Stores brake fluid used in hydraulic braking systems.

[0046] Power steering fluid reservoir: For hydraulic power steering systems, a container is needed to store the power steering fluid.

[0047] Windshield washer fluid reservoir: Stores washer fluid used to clean windshields.

[0048] Air conditioning refrigerant container: In air conditioning systems, refrigerant is usually stored in a closed loop system, but sometimes there is also a visible low-pressure side service port.

[0049] Distilled water container: In some cases, vehicles may carry distilled water to replenish coolant or battery electrolyte.

[0050] Lubricating grease container: Some vehicles may be equipped with a lubricating grease container for the periodic lubrication of moving parts.

[0051] Urea solution tank: For diesel vehicles equipped with a selective catalytic reduction (SCR) system, urea solution is used to reduce exhaust emissions.

[0052] According to an embodiment of the present invention, a method embodiment of an on-board liquid energy recovery method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0053] Figure 1 This is an embodiment of the vehicle-mounted liquid energy recovery method according to the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0054] Step S1: Obtain the vehicle's driving information and the power information of the energy storage device of the liquid energy recovery system, wherein the driving information includes at least road condition information;

[0055] Step S2: When the driving information and the power information of the energy storage device meet the preset conditions, control the liquid energy recovery system to perform the target action to convert at least part of the kinetic or potential energy of the liquid carried on the vehicle into electrical energy.

[0056] Energy storage devices include batteries, electrochemical capacitors, etc.

[0057] Step S3: If it is determined that the liquid energy recovery system generates electrical energy, control the energy storage device to perform energy storage operations.

[0058] By acquiring the vehicle's driving information and the electrical charge information of the energy storage device of the liquid energy recovery system through the above steps, and controlling the liquid energy recovery system to perform the target action when the driving information and the electrical charge information of the energy storage device meet the preset conditions, the goal of converting at least a portion of the kinetic or potential energy of the liquid carried on the vehicle into electrical energy is achieved. This realizes the technical effect of storing and utilizing the converted kinetic or potential energy of the liquid, thereby solving the technical problem of large liquid energy loss in vehicles in the prior art.

[0059] The above steps reduce the intensity of liquid sloshing, allowing the liquid to return to static state more quickly, thus improving vehicle noise and enhancing the passenger experience.

[0060] In other words, this application provides an on-board liquid energy recovery system and method that can recover and convert the energy (kinetic energy, potential energy, etc.) contained in liquid substances on the vehicle while the vehicle is in motion, store it in an energy storage container, and power other loads on the vehicle. This solves the problem of energy waste, improves energy utilization efficiency, reduces vehicle fuel and electricity consumption, and can significantly improve the noise performance of the entire vehicle.

[0061] Optionally, the vehicle's driving information and the energy storage device's power information are acquired. When the driving information and the energy storage device's power information meet preset conditions, the vehicle's liquid energy recovery system is controlled to perform a target action. This includes: acquiring vibration amplitude information, pressure information, road condition information, and vehicle speed information from the vehicle's driving information; wherein the vibration amplitude information is detected by a vibration sensor installed on the vehicle and used to store liquid; the pressure information is detected by a pressure sensor installed on the liquid storage tank; the pressure information includes at least the pressure information within each cavity structure of each liquid storage tank; and the vehicle speed information is detected by a vehicle speed sensor or acceleration sensor. When it is determined that at least one of the vibration amplitude information, pressure information, road condition information, and vehicle speed information meets preset conditions with the energy storage device's power information, the vehicle's liquid energy recovery system is controlled to perform a target action, wherein the target action includes at least controlling the liquid energy recovery system to start.

[0062] By comparing at least one of the vibration amplitude information, pressure information, road condition information, and vehicle speed information with the energy storage device's power information under preset conditions, the vehicle can determine whether to perform the target action to complete liquid energy recovery under conditions such as excessive vibration (e.g., vertical vibration), uneven pressure inside the container, driving on bumpy roads, frequent braking or starting, etc., in conjunction with the battery power.

[0063] The road condition information can be obtained from real-time image sensors, from a pre-defined geographic database, or imported by the user through an input port.

[0064] like Figure 4A schematic diagram of an optional vehicle-mounted liquid energy recovery system according to an embodiment of the present invention is shown. The energy recovery system includes a sensing module and an information collection module including a vibration sensor, a vehicle speed sensor (or acceleration sensor), a power signal from an energy storage device, and a pressure sensor. To accurately measure vibration acceleration, the vibration sensor is mounted on the liquid container. The pressure sensor is also mounted on the liquid container. The energy recovery system includes a control module, which is responsible for collecting and processing the signals from each sensor in the sensing module. Based on the signal processing results, it identifies road condition information, driving behavior, and the power status of the energy storage device, and determines whether the conditions for activating the energy recovery system are met. If the conditions are met, the control module sends a start command to the energy recovery module, and the energy recovery module begins operation. The energy recovery system includes an energy recovery module, which is responsible for converting the kinetic or potential energy of the vehicle-mounted liquid into electrical energy. The energy recovery system also includes an energy storage module, which is responsible for storing the electrical energy generated by the energy recovery module and supplying power to the vehicle's electrical loads.

[0065] Optionally, if at least one of the vibration amplitude information, pressure information, road condition information, and vehicle speed information meets preset conditions with the electrical charge information of the energy storage device, the vehicle's liquid energy recovery system is controlled to perform a target action, including: determining that the vehicle is in a state of frequent acceleration and braking based on the vehicle speed information, or determining that the vertical vibration of the vehicle has exceeded a threshold based on at least one of the vibration amplitude information and road condition information; if the vehicle is determined to be in a state of unstable driving, acquiring first pressure information and second pressure information of the liquid storage tank, wherein the first pressure information is the pressure in the first cavity structure of the liquid storage tank, and the second pressure information is the pressure in the second cavity structure of the liquid storage tank; and controlling the liquid energy recovery system to perform the target action based on the first pressure information, the second pressure information, and the electrical charge information of the energy storage device.

[0066] In other words, when it is determined that the vehicle is in a state of frequent acceleration and braking or that the vertical vibration of the vehicle has exceeded the threshold, it indicates that the vehicle has a need for liquid energy recovery. By obtaining the pressure information of different chambers in the liquid tank, the direction of gas flow can be determined, and then the liquid energy recovery system can be controlled to perform the target action, so that the liquid energy can be transferred by using the gas flow driven by the movement of the liquid.

[0067] Determining if a vehicle is in a state of frequent acceleration and braking includes: determining the number of times the accelerator and brake pedals are used and the magnitude of pedal pressure within a sampling period. If these exceed the set standards, the vehicle can be determined to be in a state of frequent acceleration and braking.

[0068] Optionally, the liquid energy recovery system is controlled to perform a target action based on the first pressure information, the second pressure information, and the power information of the energy storage device. This includes: calculating the difference between the pressures in the first cavity structure and the second cavity structure based on the first pressure information and the second pressure information to obtain the absolute value of the pressure difference between the first cavity structure and the second cavity structure; and controlling the liquid energy recovery system to perform a target action when the absolute value of the pressure difference between the first cavity structure and the second cavity structure meets a certain condition and the power information of the energy storage device is lower than a preset power threshold. The target action includes controlling the opening or closing of the first flow channel and the second flow channel connecting the first cavity structure and the second cavity structure.

[0069] Specifically, the absolute value of the pressure difference between the first and second chamber structures is determined to meet certain conditions with a preset pressure value. These conditions include the absolute value of the pressure difference being less than a certain set pressure value, indicating that the container has a liquid energy recovery requirement, thereby controlling the execution of the target action. Simultaneously, it is necessary to ensure that the energy storage device's charge level is below a preset threshold to avoid disrupting the device's charge balance or causing overcharging.

[0070] By controlling the opening or closing of the first and second flow channels connecting the first and second cavity structures, the gas inside the cavity structure can move along different paths, thereby recovering energy through the energy recovery devices in different flow channels.

[0071] like Figure 2 The diagram illustrates an optional vehicle-mounted liquid energy recovery method according to an embodiment of the present invention. After receiving a start command, the vehicle begins to collect signals through sensors and identifies road condition information, driving behavior, and the power status of the energy storage device based on the signals. When the road condition information, driving behavior, and the power status of the energy storage device meet the conditions for the energy recovery system to start, the liquid energy recovery system starts to work, converting the kinetic or potential energy of the vehicle-mounted liquid into electrical energy and storing it in the energy storage device.

[0072] Optionally, before controlling the vehicle's liquid energy recovery system to execute the target action, if the driving information and the energy storage device's power information meet preset conditions, the process includes: receiving a control command, which is used to activate the liquid energy recovery system to execute the target action, and the control command is triggered by the target object pressing the target button on the vehicle.

[0073] In other words, the energy recovery system can also be turned on and off by the driver through a human-machine interface based on driving behavior or road conditions.

[0074] Optionally, the control method further includes: recording the vehicle's driving route information, and obtaining at least one of the following based on the driving route information and the power generation information of the liquid energy recovery system: historical energy recovery information, driving route preference information, and route driving time information for each driving route.

[0075] In other words, the control method includes generating historical experience data through the vehicle's driving route information, enabling the vehicle to enter an intelligent energy storage mode. In this mode, at least one of the following is obtained: historical energy recovery information for each driving route, driving route preference information, and route driving time information. Then, the vehicle terminal automatically determines whether to control the system to execute the target action.

[0076] Optionally, before obtaining the vehicle's driving information and the energy storage device's power information, the process includes: obtaining the vehicle's current location and destination location information; generating a recommended route based on the current location and destination location information; determining a target driving route from the generated recommended routes based on driving route preference information; and generating a control strategy based on the historical energy recovery information of the driving route and the target driving route, wherein the control strategy is used to control the liquid energy recovery system to turn on and off within a target time period.

[0077] Multiple recommended routes are constructed using the current location and destination location information. The current location and destination location information are combined with the historical energy recovery information of the driving route to determine whether it has energy recovery value. If so, the liquid energy recovery system can be controlled to be turned on within the target time period. Here, having energy recovery value means that the amount of battery power recovered by the energy recovery system on the route is greater than the set amount of power.

[0078] like Figure 8 A schematic diagram of an optional vehicle-mounted liquid energy recovery system according to an embodiment of the present invention is shown. The system includes an intelligent module that records and analyzes past vehicle routes, energy recovery data for each route, high-frequency routes, and travel times. Based on the vehicle's location and navigation information input by the driver, the system intelligently determines whether to activate the energy recovery mode. For example, if driver A drove on route B six months ago, a route with high energy recovery value, and six months later the driver inputs navigation information for route B again through the human-machine interface, the intelligent module predicts that the driver will drive on that route again and notifies the control module to activate energy recovery.

[0079] Specifically, the intelligent module can also calculate the full charge time of the energy storage device based on the energy recovery power (electricity recovered per unit time), the energy recovery coefficient (defined as electricity recovered per unit distance, in kWh / km), and the current state of the battery. It can also combine the remaining time or distance to reach the destination with navigation information to determine how much electricity can be charged and display all this information, including the energy recovery power and energy recovery coefficient, on the human-machine interface.

[0080] The human-machine interface integrates display and input functions, allowing vehicle owners to autonomously turn the energy recovery system on or off based on road conditions and driving status. Alternatively, the control module can intelligently determine whether to activate energy recovery and display the question "Activate energy recovery?" to the vehicle via the human-machine interface. The owner can then send a "yes" or "no" command to the vehicle through the human-machine interface to decide whether to activate energy recovery.

[0081] According to another specific embodiment of the present invention, an on-board liquid energy recovery device is also provided, comprising: an acquisition unit, configured to acquire vehicle driving information and energy storage device power information, wherein the driving information includes at least road condition information; a control unit, configured to control the vehicle's liquid energy recovery system to perform a target action, such as converting at least a portion of the kinetic or potential energy of the liquid carried on the vehicle into electrical energy, when the driving information and energy storage device power information meet preset conditions; and a determination unit, configured to control the energy storage device to perform energy storage operations when it is determined that the liquid energy recovery system generates electrical energy.

[0082] According to another specific embodiment of the present invention, a computer-readable storage medium is also provided, the computer-readable storage medium including a stored program, wherein, when the program is running, it controls the device where the computer-readable storage medium is located to perform the above-described vehicle-mounted liquid energy recovery method.

[0083] According to another specific embodiment of the present invention, an on-board liquid energy recovery system is also provided, comprising: a liquid storage tank 1; an isolation section 2 disposed within the liquid storage tank 1 to divide the interior of the liquid storage tank 1 into multiple cavity structures, the multiple cavity structures being interconnected; a connecting flow channel group, a connecting flow channel group being disposed between each pair of cavity structures, each connecting flow channel group including two flow channels 4, the gas flow directions in the two flow channels 4 being arranged in opposite directions; an electrical energy generating device, the electrical energy generating device being connected to at least one of the liquid storage tank 1 and the flow channels 4; wherein, during the process of gas flowing between the multiple cavity structures in the liquid storage tank 1, the gas pressure ratio in the multiple cavity structures will change, and the gas and the electrical energy generating device cooperate to generate electrical energy; an energy storage device, the energy storage device being electrically connected to the electrical energy generating device, the energy storage device being used to store the electrical energy generated by the electrical energy generating device, and the energy storage device being used to supply power to on-board equipment with the stored electrical energy; wherein, the on-board liquid energy recovery system is controlled using the on-board liquid energy recovery method in the above embodiment.

[0084] By connecting the power generation device to at least one of the liquid storage tank 1 and the flow channel 4, the liquid movement causes different gas pressures in different chambers as the gas in the liquid storage tank 1 flows between multiple chamber structures. As a result, the energy of the liquid can be conducted to the power generation device through the airflow in the liquid storage tank 1 and the flow channel 4, and then stored in the energy storage device, thereby achieving the technical effect of utilizing at least a portion of the liquid energy.

[0085] Combination Figure 3 and Figure 4 As shown, Figure 3 A schematic diagram of an optional vehicle-mounted liquid energy recovery system according to an embodiment of the present invention is shown; Figure 3 The diagram also shows a generator 6 and a one-way valve 7. The isolation section 2 is an internal partition of the liquid container, dividing it into several cavities, each interconnected at its lower part. The pressure sensor 3 monitors the pressure values ​​inside each cavity of the pressure vessel. The flow channel 4 connects the cavities within the liquid container, allowing the exchange of media within each cavity. The first rotating component 5 is a rotating mechanism mounted on the flow channel 4, with one set of rotating mechanisms in each channel. The flow of media within the channel drives the rotating mechanisms to rotate. The generator 6 is mechanically connected to the first rotating component 5, and the power generation unit, driven by the first rotating component 5, converts mechanical energy into electrical energy. The generator 6 and the first rotating component 5 together constitute the power generation unit. Each flow channel 4 has one one-way valve 7, which controls the unidirectional flow of the media within the channel; the one-way valves in two channels control media flow in opposite directions. Figure 4 The sensing module in the middle is the vibration sensor 9, which is responsible for monitoring the vibration amplitude of the pressure vessel and transmitting the signal to the control module.

[0086] Optionally, the isolation section 2 includes a partition, which is disposed on the top of the liquid storage tank 1 and is disposed at a distance from the bottom of the liquid storage tank 1. The partition divides the liquid storage tank 1 into two cavity structures, and the bottoms of the two cavity structures are connected.

[0087] The liquid flows through the two cavities of the storage tank, passing through the gap reserved below the partition. In fact, the lower part of the storage tank 1 is filled with liquid. The flow of liquid between the cavities causes a change in the volume of gas in the upper part. The gas flows through the constructed channels and can then be used to do work.

[0088] Optionally, the two cavity structures can be set to have the same volume.

[0089] Without a baffle, the storage tank will form a large cavity. When the liquid sloshes, the gas in the upper part will also slosh around. Therefore, no pressure difference will be generated, and the gas will not flow in the channel, thus making it impossible to perform external work.

[0090] Optionally, the connecting flow channel group includes a first flow channel 41 and a second flow channel 42. The tops of the two cavity structures are connected through the first flow channel 41 and the second flow channel 42, respectively. Valve structures are provided on the first flow channel 41 and the second flow channel 42, and the gas flows in opposite directions in the first flow channel 41 and the second flow channel 42.

[0091] By setting up two flow channels 4 with opposite directions, regardless of the direction of gas flow, there will always be a corresponding flow channel 4 and a corresponding power generation device to convert and collect the kinetic energy in the flow process.

[0092] Optionally, the power generation device includes a mechanical power generation device connected to at least one of the first flow channel 41 and the second flow channel 42. The gas flowing through the first flow channel 41 and the second flow channel 42 drives the mechanical power generation device to rotate for power generation. The mechanical power generation device can be a generator, that is, a device that generates point current using the law of electromagnetic induction.

[0093] Preferably, there are two power generation devices, and the two power generation devices are arranged corresponding to the two flow channels 4.

[0094] Optionally, the mechanical power generation device includes: a first rotating member 5, a portion of which is disposed within a first flow channel 41; and a generator connected to the first rotating member 5. The gas flowing through the first flow channel 41 drives the first rotating member 5 to rotate, thereby driving the generator to rotate and generate electrical energy.

[0095] The first rotating component 5 can be a mechanical rotating device. For example, the first rotating component 5 can be a device with blades and the blades are connected to the central shaft. The central shaft is connected to the rotating shaft of the generator, and the blades are driven by force to make the rotating shaft of the generator cut magnetic field lines in the magnetic field.

[0096] like Figure 4 As shown, the sensing module is connected to the control module. After the vehicle starts, the sensing module collects vibration, vehicle speed, pressure, and energy storage device signals through sensors and transmits the signals to the control module. The vibration sensor collects the vertical vibration acceleration value of the liquid container and is responsible for sensing the intensity of the vertical vibration of the liquid container; there are two pressure sensors (one pressure sensor is installed in each cavity of the liquid container) and are responsible for collecting the pressure value inside the cavity.

[0097] The control module processes the vehicle speed signal to calculate the vehicle's horizontal acceleration value. Based on the acceleration signal, the control module determines whether the vehicle is in a state of frequent acceleration and braking; based on the vibration signal, it determines whether the vehicle's vertical vibration exceeds a threshold; based on the pressure signal, it determines whether the absolute value of the pressure difference between the two cavities inside the liquid container exceeds a threshold; and based on the electrical quantity signal, it determines whether the current electrical quantity of the energy storage device is below a threshold.

[0098] Figure 5 This is a schematic diagram of the control flow of an optional vehicle-mounted liquid energy recovery system according to an embodiment of the present invention. The method includes:

[0099] When the control module detects that the vehicle is in a state of frequent acceleration and braking, or that the vehicle's vertical vibration has exceeded a threshold, it indicates that the vehicle is in an unstable driving state. This unstable driving state causes the liquid to exchange flow between the cavities inside the container. A partition divides the liquid container into two parts, cavities a and b, with liquid at the bottom and gas at the top. When the liquid exchanges flow between the cavities through the notch below the partition, the air volume in the upper part of the cavity changes, causing a pressure change, resulting in a pressure difference ΔP between cavities a and b.

[0100] If the control module determines that the absolute value of the pressure difference ΔP between the two cavities of the liquid container exceeds a preset threshold, and the state of charge (SOC) of the energy storage device is lower than a preset threshold, it indicates that the energy storage device needs charging, and the current mechanical energy contained in the liquid is high, meeting the conditions for activating the energy recovery module. The control module sends a command to the energy recovery module, and the energy recovery module begins to operate.

[0101] The control module is connected to the energy recovery module. After the energy recovery module starts working, when the pressure in cavity a is higher than the pressure in cavity b (ΔP > 0), the control module controls the upper part of the one-way valve 7 to open, allowing pressurized gas to flow from cavity a to cavity b, driving the first rotating component 5 to rotate, which in turn drives the generator 6 to operate, converting mechanical energy into electrical energy. When the pressure in cavity b is higher than the pressure in cavity a (ΔP < 0), the control module controls the lower part of the one-way valve 7 to open, allowing pressurized gas to flow from cavity b to cavity a, driving the first rotating component 5 to rotate, which in turn drives the generator 6 to operate, converting mechanical energy into electrical energy.

[0102] The energy storage module is connected to the energy recovery module, and the electrical energy generated by the energy recovery module is stored in the energy storage module.

[0103] The electrical load is connected to the energy storage module. When the low-voltage electrical load is working, the energy storage module can supply power to the low-voltage electrical load.

[0104] Optionally, a speed-increasing mechanism is provided between the first rotating component 5 and the generator. Figure 6 As shown in the figure, the speed-increasing mechanism includes a drive gear and a driven gear. The diameter of the driven gear is smaller than that of the drive gear. The drive gear is connected to the first rotating member 5. The drive gear is connected to the generator through the driven gear so that when the first rotating member 5 rotates, the speed of the generator is increased through the driven gear.

[0105] The driven gear and the driving gear can be set in multiple stages to achieve a larger transmission ratio.

[0106] The speed-increasing module can increase the rotational speed of the generator shaft connected to the first rotating component 5, thereby achieving efficient power generation. The speed-increasing module provided in this embodiment is a two-stage speed-increasing module. The first stage of speed increase is achieved through a funnel-shaped flow channel, which reduces the diameter of the flow channel 4 near the first rotating component 5 to increase the wind speed. The second stage of speed increase is achieved by setting a gear transmission mechanism between the first rotating component 5 and the generator, using a large gear to drive a small gear to increase the generator speed.

[0107] Optionally, the diameter of at least one of the first flow channel 41 and the second flow channel 42 is gradually varied to increase the gas flow rate in the first flow channel 41 or the second flow channel 42.

[0108] Optionally, at least one of the first flow channel 41 and the second flow channel 42 is provided with a piezoelectric diaphragm. The piezoelectric diaphragm is electrically connected to the energy storage device. The gas flowing through the first flow channel 41 and the second flow channel 42 interacts with the piezoelectric diaphragm to generate electrical energy.

[0109] The process of generating electricity using a piezoelectric diaphragm is as follows: The piezoelectric material can be a natural crystal, ceramic, or synthetic polymer. When the piezoelectric diaphragm is subjected to pressure or deformation, its internal structure changes, causing charges to separate on the two surfaces of the diaphragm, thereby generating a voltage. The charge generated by the piezoelectric diaphragm needs to be collected through electrodes. The two surfaces of the piezoelectric diaphragm are usually coated with a conductive material so that the charge can flow to an external circuit. The collected charge flows through the external circuit and can power an external load or be stored in a capacitor or battery. The efficiency of piezoelectric power generation depends on a variety of factors, including the properties of the piezoelectric material, the magnitude of the applied pressure, the thickness and area of ​​the diaphragm, etc. The piezoelectric diaphragm can be installed within the flow channel 4 to achieve power generation.

[0110] Optionally, piezoelectric materials can be directly used to form the walls of liquid containers. If the container contains flammable liquids, such as gasoline, diesel, liquefied petroleum gas, or liquid hydrogen, an insulating layer is placed between the piezoelectric material container wall and the flammable liquid. This insulating layer transfers pressure to the piezoelectric material, preventing safety hazards. According to the piezoelectric effect, when these materials are subjected to pressure, their crystal structure undergoes minute changes, leading to the generation and separation of charges. These charges can accumulate on the material's surface, forming an electric field and thus generating an electric current. This allows mechanical energy to be converted into electrical energy.

[0111] Optionally, the inner wall of the liquid storage tank 1 is provided with a piezoelectric film layer, which is electrically connected to the energy storage device. The gas inside the liquid storage tank 1 interacts with the piezoelectric film layer to generate electrical energy.

[0112] Optionally, an insulating film layer is provided on the outer surface of the piezoelectric film layer.

[0113] Optionally, the storage tank 1 is equipped with at least one of a pressure sensor 3, a safety valve 8, and a vibration sensor 9.

[0114] Optional, Figure 7 This is a schematic diagram of an optional vehicle-mounted liquid energy recovery system according to an embodiment of the present invention. The energy recovery system includes a safety module. The safety module consists of a flow channel and a safety valve 8 installed thereon. Its function is to control the pressure valve to open and equalize the internal pressure of each cavity when the energy recovery module fails and the internal pressure of a certain cavity of the liquid container exceeds a critical value and there is a risk of explosion.

[0115] According to another aspect of the present invention, a vehicle is also provided, including an on-board liquid energy recovery system, which is the on-board liquid energy recovery system described above. This on-board liquid energy recovery system avoids energy waste, improves energy utilization, reduces fuel and electricity consumption, and increases driving range.

[0116] This application provides a vehicle for which the energy recovery system can be used not only in ordinary passenger cars, but also in off-road vehicles and commercial vehicles. Off-road vehicles often travel on bumpy roads and involve aggressive driving behavior by drivers. Commercial vehicles, such as tank trucks, sanitation sprinkler trucks, and liquefied natural gas transport vehicles, carry large volumes and masses of liquids, and are also suitable for the energy recovery system described in this application.

[0117] This application provides a processor for running programs, which may be a central processing unit (CPU), an application-specific integrated circuit (ASIC), a digital signal processing (DSP) chip, etc. The processor executes various functional applications and data processing by running a computer program stored in a storage medium. When the program runs, it executes the vehicle energy recovery method.
