[0002] A vehicle power bank (also known as an in-vehicle emergency starting power supply and a mobile charging device) is a portable energy storage device mainly used to provide temporary charging or starting support for electric vehicles or fuel vehicles. Its core functions include: replenishing power for electric vehicles, jump-starting fuel vehicles, and supplying power as an outdoor power source.

[0003] Existing vehicle power banks mainly face the following problems: in an extremely low-temperature environment, they may not be able to start the vehicle and need to be preheated in advance. Some products are equipped with a heating function, but this will consume additional power. In a continuously high-temperature environment, the battery may bulge and catch fire due to long-term exposure to the sun, so it is necessary to avoid storing it at high temperatures. In view of this, the present invention provides a vehicle power supply equipment. Summary of the Invention

[0005] To achieve the above object, the present invention provides a vehicle power supply equipment, including an external housing and a power storage component. A plurality of storage compartments are provided inside the external housing, and a plurality of height-adjusting components are provided inside the storage compartments. The height-adjusting components can relieve the vibration received by the power storage component and clean the inside of the storage compartment; one end of the height-adjusting component is connected to the inner bottom surface of the storage compartment, and the other end is connected to a multi-functional clamping component. The multi-functional clamping component can clamp the power storage component and accelerate the heat dissipation of the power storage component; the power storage component can be electrically connected to the vehicle battery.

[0006] Furthermore, the height adjustment component includes a C-shaped tube, an airbag, and a shock-absorbing spring; the C-shaped tube is made of a rigid material and is respectively arranged at the four corners of the storage compartment. The airbag is sleeved outside the C-shaped tube, and a plurality of air holes are evenly arranged on the outer surface of the airbag. One end of the airbag is connected to the inner bottom surface of the storage compartment, and the other end is connected to the multi-functional clamping component. The shock-absorbing spring is arranged inside the airbag, and the C-shaped tube, the airbag, and the shock-absorbing spring are coaxial. When the multi-functional clamping component clamps the electric energy storage component, the multi-functional clamping component slides along the height direction of the C-shaped tube and compresses the airbag and the shock-absorbing spring. When the multi-functional clamping component is unloaded, the compressed shock-absorbing spring pushes the airbag to restore its normal height.

[0007] Furthermore, the multi-functional clamping component includes a cooling component and a clamping component, and the cooling component is rotatably connected to the clamping component; the cooling component includes a first hose, a second hose, an annular end tube, a U-shaped tube, a water pump, and a water tank; the water tank is arranged at the bottom of the external housing, and the water pump is placed inside the water tank. One end of the water pump is connected to one end of the first hose, and the other end of the first hose is connected to the inner side surface of the annular end tube. The first hose passes through the external housing; one end of the second hose is connected to the water tank, and the other end is connected to the inner side surface of the annular end tube; the first hose and the second hose are respectively arranged inside adjacent two C-shaped tubes in the charging compartment of the same electric energy storage component, and both of them are coaxial with the C-shaped tube; the bottom surface of the annular end tube is connected to the top surface of the airbag, and the outer side surface of the annular end tube is connected to the U-shaped tube.

[0016] In the description of this embodiment, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" should be understood in a broad sense.

[0017] To make the purpose, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the drawings.

[0018] Reference Figures 1 to 6, this embodiment discloses a vehicle power supply device, including an external housing 100 and an electric energy storage component. A plurality of storage compartments 110 are provided in the external housing 100. A plurality of height adjustment components 200 are provided in the storage compartments 110. The height adjustment components 200 can relieve the vibration received by the electric energy storage component and clean the interior of the storage compartment 110. One end of the height adjustment component 200 is connected to the inner bottom surface of the storage compartment 110, and the other end is connected to a multi-functional clamping component 300. The multi-functional clamping component 300 can clamp the electric energy storage component. The electric energy storage component can be electrically connected to the vehicle battery. The height adjustment component 200 includes a C-shaped tube 210, an airbag 220 and a shock-absorbing spring 230. The C-shaped tube 210 is made of a rigid material and is respectively arranged at the four corners of the storage compartment 110. The airbag 220 is sleeved outside the C-shaped tube 210. A plurality of air holes are uniformly opened on the outer surface of the airbag 220. One end of the airbag 220 is connected to the inner bottom surface of the storage compartment 110, and the other end is connected to the multi-functional clamping component 300. The shock-absorbing spring 230 is arranged inside the airbag 220. The C-shaped tube 210, the airbag 220 and the shock-absorbing spring 230 are coaxial. When the multi-functional clamping component 300 clamps the electric energy storage component, the multi-functional clamping component 300 slides along the height direction of the C-shaped tube 210 and compresses the airbag 220 and the shock-absorbing spring 230. When the multi-functional clamping component 300 is in an unloaded state, the compressed shock-absorbing spring 230 pushes the airbag 220 to restore its normal height.

[0019] Further, the external housing 100 is a cube. The shapes of the plurality of storage compartments 110 opened inside it are all cube-shaped. The number of storage compartments 110 opened can be arranged according to actual working needs. The number of storage compartments 110 in this embodiment is four. The top openings of the storage compartments 110 are arranged on the top surface of the external housing 100. The number of height adjustment components 200 in a single storage compartment 110 is four groups, which are respectively arranged at the four corners of the single storage compartment 110. The height of the C-shaped tube 210 is higher than the heights of the airbag 220 and the shock-absorbing spring 230. The heights of the airbag 220 and the shock-absorbing spring 230 are the same. When the electric energy storage component and the multi-functional clamping component 300 compress the shock-absorbing spring 230, the shock-absorbing spring 230 cannot be completely compressed. The electric energy storage component can adopt existing electric energy storage devices such as vehicle power banks or storage batteries. The electrical connection method between the battery storage component and the vehicle battery can adopt existing electric vehicle charging cables. When necessary, a charging cable adapter can also be equipped to ensure that the battery storage component can be electrically connected to the vehicle battery.

[0020] The present invention is mainly applied to long-distance driving of electric vehicles. When the battery power of an electric vehicle is insufficient, the vehicle power supply device of the present invention can be placed in the vehicle trunk in advance, and then the present invention can be used to supply power to the vehicle battery; and when a person drives a vehicle out for a picnic or fishing and the vehicle needs to be charged due to insufficient battery power, the present invention can not only supply power to the vehicle, but also supply power to other devices that need electricity. When this embodiment is in use, by opening a plurality of storage compartments 110, the present invention can load a plurality of electric energy storage components, so as to meet the different power usage requirements of customers; when the customer has a large power demand, a plurality of electric energy storage components can be loaded in the present invention; when the customer has a small power demand, the number of battery energy storage components loaded in the present invention can be reduced. The specific operation is as follows: The operator first uses the multi-functional clamping component 300 to complete the clamping of the electric energy storage component. Affected by the self-weight of the electric energy storage component, the multi-functional clamping component 300 starts to slide downward along the height direction of the C-shaped tube 210. Under the push of the electric energy storage component and the multi-functional clamping component 300, the airbag 220 and the shock-absorbing spring 230 inside it are gradually compressed, and the compressed airbag 220 and shock-absorbing spring 230 gradually approach the inner bottom surface of the storage compartment 110. On the one hand, the compressed airbag 220 will discharge the gas inside it through a plurality of pores on its surface, and the discharged gas will continuously blow to the inner surface of the storage compartment 110, so as to achieve the function of blowing out the impurities on the inner surface of the storage compartment 110 until the airbag 220 stops being compressed; on the other hand, the shock-absorbing spring 230 inside the airbag 220 can shock-absorb the multi-functional clamping component 300 and the electric energy storage component it clamps, avoiding the influence of vibration on the electric energy storage component during the storage and transportation of the present invention. When the operator takes out the electric energy storage component from the present invention, the multi-functional clamping component 300 that loses the weight of the electric energy storage component starts to gradually move towards the top opening of the storage compartment 110 under the push of the shock-absorbing spring 230. Along with the reset of the shock-absorbing spring 230, the shock-absorbing spring 230 pushes the airbag 220 to reset accordingly. After resetting, the airbag 220 can re-inhale air through a plurality of pores on its surface, so that when it is compressed again, it can blow air into the storage compartment 110. That is, the shock-absorbing spring 230 can not only shock-absorb the electric energy storage component, but also help the airbag 220 to reset, and the airbag 220 after resetting can clean the inside of the storage compartment 110 after being compressed.

[0022] Further, a water filling port is provided on the side surface of the water tank 314, and the size of the water filling port is relatively large, which is convenient for the operator to perform the water filling operation and can also place the water pump into the water tank 314; through holes are opened at the four corners of the inner bottom surface of the storage compartment 110, and the through holes are coaxial with the C-shaped pipe 210, so that both the first hose 311 and the second hose can pass through the external housing 100; the first hose 311 and the second hose are exactly the same, and the only difference between them is that one end of the first hose 311 is connected to the water pump and one end of the second hose is connected to the water tank 314; the number of the annular end pipes 312, C-shaped pipes 210, airbags 220, and shock absorption springs 230 is the same, and there are four in each storage compartment 110, and the number of the first hose 311 and the second hose is two respectively; a notch is provided on the side surface of the C-shaped pipe 210, and the connection part of the first hose 311 and the annular end pipe 312 passes through the side notch of the C-shaped pipe 210; the U-shaped pipe 313 and its bottom cross pipe form an inverted A shape, and the A shape has a round head instead of a pointed head; the number of U-shaped pipes 313 in each storage compartment of the electric energy storage assembly is two, and the number of annular plates 321 is four, and two annular plates 321 are sleeved on one U-shaped pipe 313; the present invention further includes an end cover, and the end cover can cover the top surface opening of the external housing 100.

[0023] In order to clamp different types of energy storage components and reduce the heat of the energy storage components themselves to avoid the influence of excessive heat, a multifunctional clamping component 300 is set to solve the above-mentioned practical technical problems. The specific operation is as follows: the operator first puts the water pump into the water tank 314, passes the first hose 311 through the bottom hole of the storage cabin 110 along the middle circular hole of the C-tube 210, and then connects one end of the first hose 311 to the water pump; similarly, install the second hose in the adjacent C-tube 210 of the same storage cabin 110, and also pass it through the bottom hole of the storage cabin 110, so that the second hose is connected to the water tank 314; then, the other ends of the first hose 311 and the second hose are respectively connected to the inner side surfaces of different circular end tubes 312, and the circular The bottom surface of the annular end tube 312 is connected to the top surface of the airbag 220, and then the two adjacent circular end tubes 312 in the same storage compartment 110 are connected to the two ends of the U-shaped tube 313. At this time, the pipeline installation of the cooling component 310 is completed, and then the water tank 314 is filled with water; at this point, the cooling component 310 is installed; before the U-shaped tube 313 is connected to the circular end tube 312, the annular plate 321 is first sleeved along the two ends of the U-shaped tube 313 on the outside of the bottom of the horizontal tube and the U-shaped tube 313, and then the U-shaped tube 313 is connected to the circular end tube 312, and then the connecting shaft 322 is inserted into the hollow parts of the annular plate 321 and the L-shaped rotating plate 323 in turn, and then the nut is threadedly connected to the two ends of the connecting shaft 322; at this point, the clamping component 320 is assembled. When in use, the operator adjusts the tightness of the nut so that the connecting shaft 322 can rotate and slide along the annular plate 321, and adjusts the positions of the two L-shaped rotating plates 323 facing the annular plate 321 respectively, so as to adjust the distance between the two L-shaped rotating plates 323 facing each other, so as to adapt to energy storage components of different sizes and thicknesses. After the L-shaped rotating plate 323 clamps the energy storage component, the nut is tightened on the connecting shaft 322, thereby completing the clamping operation of the clamping component 320 on the energy storage component. Then, the operator turns on the water pump and uses the water pump to pump the water in the water tank 314 into the first hose 311. The water in the first hose 311 flows through the circular end tube 312 connected to it in turn, and then flows from one end of the U-shaped tube 313 into the other end thereof. Then, the water flows from the other end of the U-shaped tube 313 into another circular end tube 312, and then enters the second hose through the circular end tube 312, and then flows back into the water tank 314 through the second hose. The above operations complete the circulation of water in the cooling component 310.After that, the operator can use the clamping component 320 to clamp energy storage components of different models. The specific operations are as follows: First, place the energy storage component into different storage compartments 110, specifically between two L-shaped rotating plates 323 in the same storage compartment 110. Then, drag the L-shaped rotating plate 323 along the annular plate 321. The dragged L-shaped rotating plate 323 will drive the connecting shaft 322 connected thereto to move synchronously, so as to be able to adaptively adjust the distance between the two L-shaped rotating plates 323 according to the width dimension of the energy storage component. When the shape of the energy storage component is not a regular cuboid, the operator can rotate the L-shaped rotating plate 323 around the connecting shaft 322, so that the L-shaped rotating plate 323 can closely fit the surface of the energy storage component. When the L-shaped rotating plate 323 closely fits the energy storage component, the operator tightens the nut, and uses the side surface of the nut and the side surface of the L-shaped rotating plate 323 to clamp the annular plate 321, thus completing the clamping of the energy storage component by the clamping component 320. When the multi-functional clamping component 300 clamps the energy storage component, the circular end tube 312 moves downward along the C-shaped tube 210, and then gradually squeezes the airbag 220 and the shock-absorbing spring 230. Both the first hose 311 and the second hose communicated with the inner side surface of the circular end tube 312 can move downward along the side notch of the C-shaped tube 210, thus avoiding the interference of the first hose 311 and the second hose with the downward movement of the circular end tube 312. Obviously, by setting the external housing 100 and opening a plurality of storage compartments 110 in the external housing, the present invention can not only load multiple energy storage components, so as to meet the customer's usage requirements for different power, but also avoid the direct contact between the cold air in winter and the battery storage components in the storage compartment, thus avoiding the too low temperature of the battery storage components and ensuring the usage performance of the battery storage components in winter. By setting the multi-functional clamping component 300, the present invention can not only dissipate heat from the energy storage component, avoiding the situation that the battery bulges due to too high temperature in summer, but also clamp energy storage components of different models, improving the applicable range of the present invention. Among them, the U-shaped tube 313 and the horizontal tube arranged at the bottom thereof can not only accelerate the water circulation speed of the U-shaped tube 313, thus accelerating the heat dissipation of the energy storage component, but also cooperate with the use of the annular plate 321 to keep the annular plate 321 in a horizontal state, facilitating the clamping of the clamping component for battery energy storage components of different models. More importantly, by setting the height-adjusting component 200, the present invention can not only ensure that the battery energy storage component clamped by it can be shock-absorbed during the movement of the vehicle, avoiding the damage of the battery energy storage component due to vibration, but also clean the inside of the storage compartment 110 and the outside of the battery storage component, avoiding the damage of the battery energy storage component due to long-term dust accumulation. Through the above settings, the present invention can effectively maintain the energy storage component, improve the service life of the energy storage component, and at the same time meet the emergency use of the electric vehicle user for the battery power of the vehicle.
