Description

Technical Field

[0001] This utility model relates to the field of motor vehicle water tank technology, and in particular to a multifunctional water tank and a motor vehicle. Background Technology

[0002] For existing motor vehicles, when a vehicle starts and accelerates, the greater its weight, the greater its inertia, and the greater the grip force required by the tires. However, during driving, a greater grip load increases tire wear and power consumption, shortening tire life and increasing safety hazards. When a vehicle brakes, the further back the vehicle's center of gravity is, the higher the risk of fishtailing. In the event of a collision, the vehicle speed drops sharply; a greater weight results in greater inertia and a larger change in kinetic energy, thus causing greater injury to occupants. Therefore, a new structure is needed that can control the vehicle's weight and center of gravity based on its driving conditions. Utility Model Content

[0003] The purpose of this utility model is to provide a multifunctional water tank and a motor vehicle to solve the technical problems existing in the prior art. The various technical effects of the preferred technical solutions among the many technical solutions provided by this utility model are detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A multifunctional water tank includes a tank body, a drain pipe, regulating airbags, a compressor, and a controller. The tank body has a grid plate perpendicular to the direction of vehicle travel in its middle section. The grid plate divides the tank body into a first cavity and a second cavity. The drain pipe is located on the side of the tank body facing the direction of vehicle travel and can be closed. Two regulating airbags are respectively located inside the first cavity and the second cavity. The compressor is located on the outside of the tank body and has two input ports and two output ports respectively connected to the two regulating airbags. The controller is used to issue control signals.

[0005] Preferably, the bottom of the box body has a wavy cross-section perpendicular to the drainage direction of the drain pipe.

[0006] Preferably, a fixing hook is provided at the bottom of the box body, the fixing hook is located between the crests and troughs of the bottom of the box body, and a fixing ring that cooperates with the fixing hook is fixedly provided at the lower part of the adjusting airbag.

[0007] Preferably, the first cavity is provided with a circulating water outlet on its side, and the second cavity is provided with a circulating water inlet on its side; the circulating water outlet and the circulating water inlet are respectively connected to the water circulation system of the new energy battery pack, the engine, or the vehicle air conditioning.

[0008] Preferably, the circulating water outlet is connected to a water outlet solenoid valve, and the water outlet solenoid valve is electrically connected to the controller.

[0009] Preferably, the drain pipe has a venturi structure, with the smaller diameter side of the drain pipe located on the side closer to the housing, and the larger diameter side of the drain pipe located on the side away from the housing.

[0010] Preferably, the drain pipe is equipped with a drain solenoid valve, which is electrically connected to the controller and can receive electrical control signals from the controller.

[0011] Preferably, the top of the box is provided with several water inlets, and a cover plate is detachably connected to each water inlet.

[0012] Preferably, an intake solenoid valve is provided on the intake pipe connecting the regulating airbag to the compressor, and an exhaust solenoid valve is provided on the exhaust pipe connecting the regulating airbag to the compressor. The intake solenoid valve and the exhaust solenoid valve are electrically connected to the controller.

[0013] A motor vehicle includes the motor vehicle body and the aforementioned multi-functional water tank.

[0014] The beneficial effects of this utility model are as follows: 1. By setting two regulating airbags, which occupy the internal space of the first and second chambers respectively, and the compressor controls the air intake and exhaust of the regulating airbags, when there is more gas in the regulating airbag, the water storage space of the corresponding chamber is reduced, which means that the weight of that half-section is reduced. When there is less gas in the regulating airbag, the water storage space of the corresponding chamber is increased, which means that the weight of that half-section is increased. Thus, by controlling the air intake and exhaust of the two regulating airbags by the compressor, the center of gravity of the multi-functional water tank can be controlled to move forward and backward.

[0015] 2. In actual use, the controller monitors the vehicle speed. When stationary, the water volume is concentrated at the front of the vehicle. When the vehicle starts and accelerates to a speed exceeding the set speed threshold or a travel time exceeding the set time threshold, the water volume is concentrated at the rear of the vehicle, shifting the center of gravity backward to improve acceleration performance. When the vehicle brakes and decelerates, the water volume is concentrated at the front of the vehicle, shifting the center of gravity forward to prevent fishtailing.

[0016] 3. When a vehicle collision occurs, the controller receives the airbag deployment signal and immediately controls the drain pipe to open. Because the drain pipe uses a venturi structure, the water flow velocity is relatively high. The water in the tank moves in the direction of vehicle movement due to inertia, further increasing the water discharge speed. At the same time, it controls the two regulating airbags to inflate simultaneously, compressing the water storage space in the two chambers, further increasing the water discharge speed. This achieves rapid water discharge from the tank, reduces the vehicle's weight, and reduces the risk of injury to occupants due to changes in vehicle kinetic energy. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Reference Figures 1 to 4 This utility model provides a multifunctional water tank, including a tank body 1, a drain pipe 2, an adjusting airbag 3, a compressor 4, and a controller. The middle part of the tank body 1 is provided with a grid plate 11 perpendicular to the direction of vehicle travel. The tank body 1 is divided by the grid plate 11 to form a first cavity 12 and a second cavity 13. The drain pipe 2 is provided on the side of the tank body 1 facing the direction of vehicle travel and can be closed. The two adjusting airbags 3 are respectively provided inside the first cavity 12 and the second cavity 13. The compressor 4 is provided on the outside of the tank body 1 and has two input ports and two output ports respectively connected to the two adjusting airbags 3. The controller is used to send control signals.

[0023] Two regulating airbags 3 occupy the internal space of the first cavity 12 and the second cavity 13 respectively. The compressor 4 controls the air intake and exhaust of the regulating airbags 3. When there is more gas in the regulating airbag 3, the water storage space of its corresponding cavity is reduced, which means that the weight of this half-section is reduced. When there is less gas in the regulating airbag 3, the water storage space of its corresponding cavity is increased, which means that the weight of this half-section is increased. Thus, by controlling the air intake and exhaust of the two regulating airbags 3 by the compressor 4, the center of gravity of the multi-functional water tank can be controlled to move forward and backward.

[0024] In actual use, the controller monitors the vehicle speed. When stationary, the water volume is concentrated at the front of the vehicle. When the vehicle starts and accelerates to a speed exceeding the set speed threshold or a travel time exceeding the set time threshold, the water volume is concentrated at the rear of the vehicle, shifting the center of gravity backward and improving acceleration performance.

[0025] When the vehicle brakes and slows down, the water volume is concentrated on the front of the vehicle, shifting the center of gravity forward to prevent fishtailing.

[0026] When a vehicle collision occurs, the controller activates the drain pipe 2 to quickly drain the water from the tank 1, reducing the vehicle's weight and minimizing the impact of changes in the vehicle's kinetic energy on the occupants.

[0027] As an optional implementation, the bottom of the housing 1 has a wavy cross-section perpendicular to the drainage direction of the drain pipe 2. This configuration forms a wavy structure, which increases the structural strength of the bottom of the housing 1 and reduces the influence of the regulating airbag 3 on the water flow. When there is less gas in the regulating airbag 3, the space inside the housing 1 is released, and the water can be discharged from the drain pipe 2 through the bottom of the housing 1.

[0028] As an optional implementation, a fixing hook 14 is provided at the bottom of the box body 1. The fixing hook 14 is located between the crests and troughs of the bottom of the box body 1, and a fixing ring 33 that cooperates with the fixing hook 14 is fixedly provided at the lower part of the adjusting airbag 3.

[0029] The relative position of the adjusting airbag 3 is fixed to prevent the adjusting airbag 3 from being misaligned and causing blockage of the drain pipe 2. When the adjusting airbag 3 needs to be replaced, the fixing ring 33 on the adjusting airbag 3 is removed from the fixing hook 14, and the adjusting airbag 3 can be replaced quickly.

[0030] As an optional implementation, a circulation outlet 15 is provided on the side of the first cavity 12, and a circulation inlet 16 is provided on the side of the second cavity 13; the circulation outlet 15 and the circulation inlet 16 are respectively connected to the water circulation system of the new energy battery pack, the engine, or the vehicle air conditioning.

[0031] Under normal driving conditions, the water in box 1 can be used for water circulation in the new energy battery pack, engine, or vehicle air conditioner.

[0032] As an optional implementation, the circulating water outlet 15 is connected to a water outlet solenoid valve 19, which is electrically connected to the controller, and the controller is connected to the vehicle's water circulation system temperature sensing signal.

[0033] As an optional implementation, the drain pipe 2 has a venturi structure, with the smaller diameter side of the drain pipe 2 located on the side closer to the housing 1 and the larger diameter side of the drain pipe 2 located on the side away from the housing 1. This arrangement increases the water flow speed during drainage, so that the water in the housing 1 can be quickly discharged when it is necessary to quickly reduce the weight of the vehicle body in an emergency.

[0034] As an optional implementation, a drain solenoid valve 21 is provided on the drain pipe 2. The drain solenoid valve 21 is electrically connected to the controller and can receive electrical control signals from the controller. The drain solenoid valve 21 is controlled by the controller to open and close. The controller is connected to the airbag control signal of the vehicle cabin.

[0035] As an optional implementation, the top of the tank 1 is provided with a plurality of water inlets 17, and a cover plate 18 is detachably connected to the water inlets 17, so that water can be quickly injected into the tank 1 through the water inlets 17.

[0036] As an optional implementation, an intake solenoid valve 31 is provided on the intake pipe connecting the airbag 3 and the compressor 4, and an exhaust solenoid valve 32 is provided on the exhaust pipe connecting the airbag 3 and the compressor 4. The intake solenoid valve 31 and the exhaust solenoid valve 32 are electrically connected to the controller, and the controller is connected to the vehicle speed signal on the vehicle's instrument panel.

[0037] Example 2 This utility model also provides a motor vehicle, including the motor vehicle body and the aforementioned multifunctional water tank.

[0038] The working principle of the multifunctional water tank mentioned in this utility model is as follows: The controller monitors the vehicle speed in real time. When stationary, the compressor 4 draws gas from the regulating airbag 3 located at the front of the driving direction and replenishes gas to the regulating airbag 3 located at the rear of the driving direction. This makes the water storage space inside the tank 1 located at the front of the driving direction much larger than the water storage space located at the rear of the driving direction. In other words, the amount of water inside the tank 1 located at the front of the driving direction is much larger than the amount of water located at the rear of the driving direction. This controls the water volume to be concentrated at the front of the vehicle, causing the center of gravity of the multi-functional water tank to shift forward.

[0039] When the vehicle starts and accelerates to a speed exceeding the set speed threshold or a travel time exceeding the set time threshold, the compressor 4 draws gas from the regulating airbag 3 located at the rear of the driving direction and replenishes gas to the regulating airbag 3 located at the front of the driving direction. This makes the water storage space inside the tank 1 located at the rear of the driving direction much larger than the water storage space located at the front of the driving direction. In other words, the amount of water in the space inside the tank 1 located at the rear of the driving direction is much larger than the amount of water located at the front of the driving direction. This controls the water volume to concentrate at the rear of the vehicle, causing the center of gravity of the multi-functional water tank to shift rearward and improve acceleration performance.

[0040] When the vehicle brakes and decelerates, the compressor 4 draws gas from the regulating airbag 3 located at the front of the driving direction and replenishes the regulating airbag 3 located at the rear of the driving direction. This makes the water storage space inside the tank 1 located at the front of the driving direction much larger than the water storage space located at the rear of the driving direction. In other words, the amount of water in the space inside the tank 1 located at the front of the driving direction is much larger than the amount of water located at the rear of the driving direction. This controls the water volume to be concentrated at the front of the vehicle, causing the center of gravity of the multi-functional water tank to shift forward and preventing fishtailing.

[0041] When a collision occurs, the controller receives the airbag deployment signal and immediately controls the drain pipe 2 to open. Because the drain pipe 2 uses a venturi structure, its water flow velocity is relatively high. The water in the tank 1 moves in the direction of vehicle movement due to inertia, further increasing the discharge speed of the water in the tank 1. At the same time, it controls the two regulating airbags 3 to inflate simultaneously, compressing the water storage space in the two chambers, further increasing the discharge speed of the water in the tank 1. This achieves rapid discharge of water from the tank 1, reducing the vehicle's weight and minimizing the harm to the occupants caused by changes in the vehicle's kinetic energy.

[0042] The total weight of the water in tank 1 is approximately 250 kg, and the weight of the water in tank 1 alone is 150 kg. Since current cars are designed to be lightweight, the vehicle weight is generally less than 1.5 tons. This means that the mass of the water is about 1 / 10 of the vehicle weight, and its impact on the vehicle weight is quite considerable.

[0043] In summary, in this invention, the two regulating airbags 3 occupy the internal spaces of the first cavity 12 and the second cavity 13, respectively. The compressor 4 controls the intake and exhaust of the regulating airbags 3. When there is more gas in the regulating airbags 3, the water storage space of the corresponding cavity decreases, meaning that the weight of that half-section decreases. When there is less gas in the regulating airbags 3, the water storage space of the corresponding cavity increases, meaning that the weight of that half-section increases. Thus, by controlling the intake and exhaust of the two regulating airbags 3 by the compressor 4, the center of gravity of the multi-functional water tank can be controlled to shift forward and backward. The controller monitors the vehicle speed. In a stationary state, the water volume is concentrated at the front of the vehicle. When the vehicle starts and accelerates to a speed exceeding a set speed threshold or a driving time exceeding a set time threshold, the water volume is adjusted accordingly. When the vehicle is in motion, the water volume is concentrated at the rear of the vehicle, shifting the center of gravity rearward and improving acceleration performance. When the vehicle brakes and decelerates, the water volume is concentrated at the front of the vehicle, shifting the center of gravity forward and preventing fishtailing. In the event of a collision, the controller receives a signal to deploy the airbags in the passenger compartment and immediately controls the drain pipe 2 to open. Due to the Venturi structure of the drain pipe 2, the water flow velocity is high, and the water in the tank 1 moves forward due to inertia, further increasing the discharge speed of the water in the tank 1. Simultaneously, the two regulating airbags 3 are inflated, compressing the water storage space in the two chambers, further increasing the discharge speed of the water in the tank 1. This achieves rapid discharge of water from the tank 1, reducing the vehicle's weight and minimizing the harm to occupants caused by changes in the vehicle's kinetic energy. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0044] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
