One end of the airbag is connected to the inner bottom surface of the storage cabin, and the other end is connected to the multi-functional clamping component. The shock-absorbing spring is arranged inside the airbag, and the C-tube, airbag and 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-tube and compresses the airbag and the shock-absorbing spring; when the multi-functional clamping assembly is in an unloaded state, the compressed shock-absorbing spring pushes the airbag to return to its normal height.

[0009] Compared with the prior art, the present invention has at least the following beneficial effects:

[0010] 1. A vehicle power supply device is provided with a height adjustment assembly comprising an airbag, a shock-absorbing spring, and a C-shaped tube. The shock-absorbing spring not only reduces vibration of the energy storage assembly but also helps reset the airbag. The reset airbag cooperates with a multifunctional clamping assembly to clean the interior of the storage compartment after compression.

[0011] 2. A vehicle power supply device is provided with a multifunctional clamping component, which can not only dissipate heat from the electric energy storage component, but also clamp different types of electric energy storage components; under the condition of continuous high temperature in summer, the first hose, the second hose, the circular end tube, the U-shaped tube, the water pump and the water tank can dissipate heat from the battery storage component to prevent the battery storage component from bulging due to excessive temperature; among them, the U-shaped tube and the horizontal tube provided at the bottom can not only accelerate the water circulation speed of the U-shaped tube, thereby accelerating the heat dissipation of the electric energy storage component, but also cooperate with the use of the annular plate to enable the annular plate to remain in a horizontal state for clamping the electric energy storage component.

[0012] 3. A C-shaped tube installed in a vehicle power supply device not only ensures the vertical movement of the shock-absorbing spring and airbag, but also enables the first and second hoses inside the tube to move along the notch of the C-shaped tube, thereby facilitating the coordinated operation of the height adjustment component and the multi-functional clamping component.

[0013] 4. A vehicle power supply device has multiple storage compartments, enabling it to accommodate multiple energy storage components, thereby meeting customers' varying power requirements.

Furthermore, in low-temperature winter environments, the provision of an external housing prevents direct contact between cold air and the battery storage components, thereby avoiding the situation where the battery storage components in the storage compartments are too cold and require preheating.

[0023] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0024] refer to Figures 1 to 6The present embodiment discloses a vehicle power supply device, including an external shell 100 and an energy storage component. A plurality of storage compartments 110 are provided in the external shell 100. A plurality of height adjustment components 200 are provided in the storage compartments 110. The height adjustment components 200 can alleviate the vibration of the energy storage component and clean the interior of the storage compartments 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 multifunctional clamping component 300. The multifunctional clamping component 300 can clamp the energy storage component. The energy storage component can be electrically connected to the vehicle battery. The height adjustment component 200 includes a C-tube 210, an airbag 220 and a shock-absorbing spring 230. The C-tube 210 is made of hard material and is respectively provided with At the four corners of the storage compartment 110, the airbag 220 is sleeved on the outside of the C-shaped tube 210, and a plurality of air holes are evenly 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 assembly 300. The shock-absorbing spring 230 is arranged inside the airbag 220, and the C-shaped tube 210, the airbag 220 and the shock-absorbing spring 230 are coaxial; when the multi-functional clamping assembly 300 clamps the electric energy storage assembly, the multi-functional clamping assembly 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 assembly 300 is unloaded, the compressed shock-absorbing spring 230 pushes the airbag 220 to return to its normal height.

[0025] Furthermore, the external shell 100 is a cube, and the multiple storage compartments 110 opened inside it are all in the shape of a cube. The number of storage compartments 110 opened can be arranged according to actual work needs. The number of storage compartments 110 in this embodiment is four, and the top opening of the storage compartment 110 is set on the top surface of the external shell 100; the number of height adjustment components 200 in a single storage compartment 110 is four groups, which are respectively set at the four corners of the single storage compartment 110; the height of the C-tube 210 is higher than the height of the airbag 220 and the shock-absorbing spring 230, and the height of the airbag 220 is consistent with the height of the shock-absorbing spring 230; when the 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 energy storage component can adopt an existing vehicle power bank or battery and other energy storage devices; the battery storage component and the vehicle battery can be electrically connected using an existing electric vehicle charging cable, and a charging cable adapter can be provided when necessary to ensure that the battery storage component can be electrically connected to the vehicle battery.

[0026] The present invention is mainly used for long-distance driving of electric vehicles. When the power of the electric vehicle is insufficient, the vehicle power supply device can be placed in the trunk of the vehicle in advance, and the vehicle battery can be powered by the present invention. When people drive the vehicle out for a picnic or fishing, the vehicle needs to be charged due to insufficient power. The present invention can power both the vehicle and other devices that need electricity. When this embodiment is in use, by opening multiple storage compartments 110, the present invention can load multiple energy storage components, thereby meeting the customer's needs for different power usage. When the customer's power demand is large, multiple energy storage components can be loaded in the present invention. When the customer's power demand is small, the number of battery storage components loaded in the present invention can be reduced. The specific operation is as follows: the operator first uses the multifunctional clamping assembly 300 to clamp the energy storage assembly. Under the influence of the self-weight of the energy storage assembly, the multifunctional clamping assembly 300 begins to slide downward along the height direction of the C-shaped tube 210. Under the push of the energy storage assembly and the multifunctional clamping assembly 300, the airbag 220 and the shock-absorbing spring 230 inside it are gradually compressed. The compressed airbag 220 and the shock-absorbing spring 230 gradually approach the bottom surface of the storage compartment 110. On the one hand, the compressed airbag 220 will discharge the internal gas through the multiple air holes on its surface. The discharged gas will continuously blow onto the inner surface of the storage compartment 110, thereby achieving the function of blowing impurities on the inner surface of the storage compartment 110 out of the interior until the airbag 220 stops compressing. On the other hand, the shock-absorbing spring 230 inside the airbag 220 can reduce the vibration of the multifunctional clamping assembly 300 and the energy storage assembly it clamps, thereby preventing the impact of vibration on the energy storage assembly during storage and transportation of the present invention. When the operator takes the energy storage component out of the present invention, the multifunctional clamping component 300, which has lost the weight of the energy storage component, begins to gradually move toward the top opening of the storage compartment 110 under the push of the shock-absorbing spring 230, and as the shock-absorbing spring 230 is reset, the shock-absorbing spring 230 pushes the airbag 220 to reset as well. After the reset, the airbag 220 can again inhale air through the multiple air holes on its surface so that it can blow air into the storage compartment 110 when it is compressed again. That is, the shock-absorbing spring 230 can both dampen the energy storage component and help reset the airbag 220. After the reset, the airbag 220 can clean the inside of the storage compartment 110 after compression.

[0027] As a further solution of this embodiment: the multifunctional clamping assembly 300 can accelerate the heat dissipation of the electric energy storage assembly; the multifunctional clamping assembly 300 includes a cooling component 310 and a clamping component 320, and the cooling component 310 is rotatably connected to the clamping component 320; the cooling component 310 includes a first hose 311, a second hose, a circular end pipe 312, a U-shaped pipe 313, a water pump and a water tank 314; the water tank 314 is arranged at the bottom of the external shell 100, and a water pump is placed in the water tank 314, the water pump is connected to one end of the first hose 311, and the other end of the first hose 311 is connected to the inner side of the circular end pipe 312, and the first hose 311 passes through the external shell 100; one end of the second hose is connected to the water tank 314, and the other end is connected to the inner side of the circular end pipe 312; the first hose 311 and the second hose are respectively arranged on the same electric energy storage assembly The inner sides of two adjacent C-tubes 210 in the charging cabin are coaxial with the C-tube 210; the bottom surface of the circular end tube 312 is connected to the top surface of the airbag 220, and the outer side surface of the circular end tube 312 is connected to the U-shaped tube 313, and the two ends of the U-shaped tube 313 are respectively connected to the two adjacent circular end tubes 312. The interior of the U-shaped tube 313 near its U-shaped bottom surface also includes a horizontal tube; the clamping assembly connects the U-shaped tube 313 and its bottom horizontal tube; the clamping component 320 includes two annular plates 321, a connecting shaft 322 and an L-shaped rotating plate 323; each annular plate 321 is sleeved on the outside of the U-shaped tube 313, the horizontal tube and the connected shaft 322, and the two annular plates 321 are respectively tightly attached to the two vertical ends of the U-shaped tube 313, and the two ends of the connecting shaft 322 are respectively rotated and slidably connected to the two annular plates 321, and the middle part of the connecting shaft 322 vertically passes through the L-shaped rotating plate 323.

[0028] Furthermore, a water filling port is provided on the side of the water tank 314, and the water filling port is large in size, which is convenient for the operator to perform water filling operations 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 tube 210, so that the first hose 311 and the second hose can pass through the external shell 100; the first hose 311 and the second hose are exactly the same, and the only difference between the two 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 circular end tubes 312, the C-shaped tube 210, the airbags 220, and the shock-absorbing springs 230 is the same. There are four U-tubes 313 in each storage compartment 110, with two first hoses 311 and two second hoses respectively; a notch is provided on the side of the C-tube 210, and the connection between the first hose 311 and the circular end tube 312 passes through the side notch of the C-tube 210; the U-tube 313 and its bottom horizontal tube form an inverted A-shape, and the A-shape has a round head rather than a pointed head; there are two U-tubes 313 in each storage compartment of the energy storage component, and there are four annular plates 321, and two annular plates 321 are sleeved on one U-tube 313; the present invention also includes an end cover, which can cover the top opening of the external shell 100.

[0029] 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, the second hose is installed in the adjacent C-tube 210 of the same storage cabin 110, and also passes 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 connecting the U-shaped tube 313 to the circular end tube 312, first put the annular plate 321 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 connect the U-shaped tube 313 to the circular end tube 312, and then insert the connecting shaft 322 into the hollow parts of the annular plate 321 and the L-shaped rotating plate 323 in turn, and then thread the nut to connect the two ends of the connecting shaft 322; at this point, the clamping component 320 is assembled. During 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 facing L-shaped rotating plates 323 relative to the annular plate 321, and the distance between the two facing L-shaped rotating plates 323, so as to adapt to energy storage components of different sizes and thicknesses. After the L-shaped rotating plates 323 clamp 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 pipe 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 pipe 312, and then enters the second hose through the circular end pipe 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.Afterwards, the operator can use the clamping component 320 to clamp different types of energy storage components. The specific operations are as follows: first, the energy storage component is placed in different storage compartments 110, specifically placed between the two L-shaped rotating plates 323 in the same storage compartment 110; then, the L-shaped rotating plate 323 is dragged along the annular plate 321, and the dragged L-shaped rotating plate 323 will drive the connecting shaft 322 connected to it to move synchronously, so that the distance between the two L-shaped rotating plates 323 can be adaptively adjusted according to the width size of the energy storage component; when the shape of the energy storage component is not a conventional rectangular parallelepiped, the operator can rotate the L-shaped rotating plate 323 around the connecting shaft 322, so that the L-shaped rotating plate 323 can fit tightly against the surface of the energy storage component; when the L-shaped rotating plate 323 fits tightly against the energy storage component, the operator tightens the nut and uses the side of the nut and the side of the L-shaped rotating plate 323 to clamp the annular plate 321, thereby completing the clamping of the energy storage component by the clamping component 320. After the multifunctional clamping assembly 300 clamps the electric energy storage assembly, the annular end tube 312 moves downward along the C-shaped tube 210, and then gradually squeezes the airbag 220 and the shock-absorbing spring 230. The first hose 311 and the second hose connected to the inner side of the annular end tube 312 can both move downward along the side notch of the C-shaped tube 210, thereby preventing the first hose 311 and the second hose from interfering with the downward movement of the annular end tube 312. Obviously, the present invention, by providing an external shell 100 and opening multiple storage compartments 110 within the external shell, can not only enable the present invention to load multiple electric energy storage assemblies, thereby meeting the customer's needs for different power usage, but also prevent the cold air in winter from directly contacting the battery storage assembly in the storage compartment, thereby preventing the battery storage assembly from being too cold and ensuring the performance of the battery storage assembly in winter. The present invention, by providing a multifunctional clamping assembly 300, can not only achieve heat dissipation of the energy storage assembly, thereby avoiding the situation where the battery bulges due to excessive temperature in the summer, but also clamp different types of energy storage assemblies, thereby increasing the scope of application of the present invention. Among them, the U-shaped tube 313 and the horizontal tube provided at its bottom can not only accelerate the water circulation speed of the U-shaped tube 313, thereby accelerating the heat dissipation of the energy storage assembly, but also cooperate with the use of the annular plate 321 so that the annular plate 321 can remain in a horizontal state, facilitating the clamping of different types of battery energy storage assemblies. More importantly, the present invention, by providing a height adjustment assembly 200, can not only ensure that the present invention can dampen the vibration of the battery energy storage assembly it clamps during the movement of the vehicle, thereby avoiding damage to the battery energy storage assembly due to vibration, but also clean the interior of the storage compartment 110 and the exterior of the battery storage assembly, thereby avoiding damage to the battery energy storage assembly due to long-term dust accumulation. Through the above-mentioned arrangement, the present invention can effectively maintain the energy storage assembly, increase the service life of the energy storage assembly, and meet the emergency use needs of electric vehicle users for the vehicle battery power.
