Fixing holes are respectively provided on the surfaces of the second support block 48, the first support block 47, the third support block 49 and the fourth support block 50, and pins are inserted into the fixing holes.

[0042] In this embodiment, the housing 1 and the equipment box 2 are placed in the trunk of a car. When the electric car needs to be charged, the sealing cover 13 is rotated and the sliding handle 31 is used to pull the slide plate 22 and the main shaft 15 from the inside of the housing 1 to the outside, and the fourth folding plate 39 and the first folding plate 26 are rotated respectively, which respectively drive the third folding plate 29 and the second folding plate 28 to rotate relative to each other until the second support block 48 contacts the first support block 47, the third support block 49 contacts the fourth support block 50, the fourth folding plate 39 and the third folding plate 29 are in a straight line, and the first folding plate 26 and the second folding plate 28 are in a straight line.

[0043] Furthermore, due to the elastic force of the tensioning torsion spring at the connection between the fourth folding plate 39 and the skateboard 22, the second support block 48 and the first support block 47 are always in contact with the third support block 49 and the fourth support block 50 respectively. The surfaces of the second support block 48, the first support block 47, the third support block 49 and the fourth support block 50 are provided with fixing holes, and pins are used to fix the second support block 48 and the first support block 47 and the third support block 49 and the fourth support block 50 respectively. The movable wheel 30 and the torsion rod 33 rotate outward under the elastic force of the motion torsion spring 34.

The shell 1 and the equipment box 2 are pulled out of the car trunk by pulling the two movable handles 5, and the fixed wheel 12 rolls inside the trunk, reducing the friction between the shell 1 and the car trunk, and at the same time protecting the car trunk.

[0044] Among them, the skateboard 22 slides back into the interior of the shell 1. At this time, with the two movable wheels 30 as the fulcrum, the movable handle 5 and the sliding handle 31 are pulled to pull the shell 1 and the equipment box 2 out from the inside of the car trunk, so that the fourth folding plate 39 and the third folding plate 29 are tilted to one end until the fourth folding plate 39 and the third folding plate 29 are located below the shell 1 and the equipment box 2. One hand pulls the movable handle 5 and the other hand pulls the sliding handle 31 to move the device to the vicinity of the car charging port. One end of the charging cable is connected to household electricity, and the other end is connected to the connecting plug 8. By plugging the main charging gun 4 into the car charging port, the AC power is converted into high-voltage DC power through a series of operations such as filtering, rectification and transformation of the conversion circuit board 18 to charge the electric car, which makes it convenient to take out the device from the car trunk and quickly transfer the device.

[0045] What needs to be explained more is that, in the process of moving the shell 1 and the equipment box 2, the shell 1 and the equipment box 2 squeeze the first folding plate 26 and the second folding plate 28, driving the extrusion sleeve 38 to slide on the sliding end 17 to squeeze the buffer spring 37, making it convenient to move the shell 1 and the equipment box 2 on roads with poor road conditions, thereby reducing the vibration of the shell 1 and the equipment box 2 during the movement.

A gasoline engine 20 is fixedly connected to the top inner wall of the equipment box 2 near the oil tank 6, and a generator 19 is provided at the bottom of the gasoline engine 20.

[0049] In this embodiment, when the battery pack 36 needs to be carried, the battery pack 36 is connected to the equipment box 2, and the threaded rod 27 is rotated by rotating the handle 11, thereby driving the movable sleeve 25 to slide to one side, and the equipment box 2 is rotated through the middle plate 24 to expose the two connecting plates 40 at the bottom of the equipment box 2, and connected to the connecting plate 40 through the connecting block 43 on one side of the battery pack 36.

[0050] Furthermore, the connecting block 43 is stuck in the inside of the slot, and the connecting block 43 squeezes the limit rod 46 so that the limit rod 46 is stuck in the inside of the connecting slot 44. When the battery pack 36 needs to be removed from the top of the equipment box 2, the limit rod 46 slides out from the inside of the connecting slot 44 by pulling the quick release handle 10, and the connecting block 43 slides out from the inside of the slot on the connecting plate 40, thereby achieving the effect of quickly connecting and quickly disassembling the equipment box 2 and the battery pack 36.

[0051] In this embodiment, when camping outdoors, the battery pack 36 can be used to charge lighting, household appliances, or digital devices such as mobile phones. By connecting household appliances or digital devices such as mobile phones to the connection plug 8, the power supply needs of outdoor camping are met.

[0052] In this embodiment, the fuel tank 6 is filled with gasoline in advance. When the electric vehicle needs to be charged and there is no charging station nearby, the gasoline engine 20 is started to drive the generator 19 to rotate. The rotation of the generator 19 converts mechanical energy into electrical energy to charge the electric vehicle. When working outdoors, there is no need to worry about the battery life of the electric vehicle, which increases the battery life of the electric vehicle.

[0053] Working principle: When in use, the device is placed in the trunk of a car. When the electric car needs to be charged, the sealing cover 13 is rotated and the sliding handle 31 is used to pull the slide plate 22 and the main shaft 15 out from the inside of the housing 1 to the outside, and the fourth folding plate 39 and the first folding plate 26 are rotated respectively, which respectively drives the third folding plate 29 and the second folding plate 28 to rotate relative to each other until the second support block 48 and the first support block 47 contact (such as Figure 11As shown in the figure, the third support block 49 is in contact with the fourth support block 50, the fourth folding plate 39 and the third folding plate 29 are in a straight line, the first folding plate 26 and the second folding plate 28 are in a straight line, and due to the elastic force of the tensioning torsion spring at the connection between the fourth folding plate 39 and the slide plate 22, the second support block 48 and the first support block 47 are always in contact with the third support block 49 and the fourth support block 50, respectively. The surfaces of the second support block 48, the first support block 47, the third support block 49 and the fourth support block 50 are provided with fixing holes, and pins are used to fix the second support block 48 and the first support block 47, and the third support block 49 and the fourth support block 50, respectively. The movable wheel 30 and the torsion rod 3 Under the elastic force of the motion torsion spring 34, the outer shell 1 and the equipment box 2 rotate outward. At this time, the two movable wheels 30 touch the ground, and the outer shell 1 and the equipment box 2 are still inside the car trunk. By pulling the two movable handles 5, the outer shell 1 and the equipment box 2 are pulled out of the car trunk. The fixed wheels 12 roll inside the trunk, reducing the friction between the outer shell 1 and the car trunk. The slide plate 22 slides back into the inner shell 1. At this time, with the two movable wheels 30 as the fulcrum, the movable handle 5 and the sliding handle 31 are pulled to pull the outer shell 1 and the equipment box 2 out of the car trunk, causing the fourth folding plate 39 and the third folding plate 29 to tilt to one end, so that the fourth folding plate 39 and the third folding plate 29 are located below the outer shell 1 and the equipment box 2. One hand pulls Move the moving handle 5 with your other hand, pull the sliding handle 31 with your other hand, move the device to the vicinity of the car charging port, release the moving handle 5, place the device directly on the ground, connect the household electricity through one end of the charging cable, and connect the other end to the connection plug 8. By plugging the main charging gun 4 into the car charging port, through a series of operations such as filtering, rectification and transformation of the conversion circuit board 18, the AC power is converted into high-voltage DC power to charge the electric car, which makes it convenient to take the device out of the car trunk and quickly transfer the device. In the process of moving the shell 1 and the device box 2, the shell 1 and the device box 2 squeeze the first folding plate 26 and the second folding plate 28, driving the extrusion sleeve 38 to slide on the sliding end 17 to squeeze the buffer spring 37 , which makes it easy to move the shell 1 and the equipment box 2 on roads with poor road conditions, and reduces the vibration of the shell 1 and the equipment box 2 during movement. When other electric vehicles need to be charged and there is no charging pile nearby, one end of the main charging gun 4 is inserted into the electric vehicle with power, and one end of the auxiliary charging gun 3 is inserted into the charging port of other electric vehicles that need to be charged, so as to achieve the effect of using the battery on the electric vehicle to charge other electric vehicles. When the battery pack 36 needs to be carried, the battery pack 36 is connected to the equipment box 2, and the threaded rod 27 is rotated by rotating the rotating handle 11, thereby driving the movable sleeve 25 to slide to one side, and the equipment box 2 is driven to rotate through the middle plate 24, exposing the two connecting plates 40 at the bottom of the equipment box 2 (as shown in FIG. Figures 6 to 9As shown in the figure), the battery pack 36 is connected to the connecting plate 40 through the connecting block 43 on one side of the battery pack 36. The connecting block 43 is stuck in the inside of the card slot. The limit block 45 is used to limit the left and right sliding of the connecting block 43 in the card slot. The connecting block 43 squeezes the limit rod 46 so that the limit rod 46 is stuck in the inside of the connecting slot 44. When the battery pack 36 needs to be removed from the top of the equipment box 2, the limit rod 46 is pulled out of the inside of the connecting slot 44 by pulling the quick release handle 10, so that the connecting block 43 slides out from the inside of the card slot on the connecting plate 40, thereby achieving the effect of quickly connecting and quickly removing the equipment box 2 and the battery pack 36. As a result, when camping outdoors, the battery pack 36 can meet the charging needs of lighting, household appliances or digital devices such as mobile phones. By connecting household appliances or digital devices such as mobile phones to the connection plug 8, the power supply needs of outdoor camping are met.
