However, during self-driving tours, it is inevitable that the vehicle will be damaged due to road conditions and other problems. Therefore, it is necessary to carry a repair toolbox with you. When the vehicle is damaged, tire blowouts are a common problem and a problem that delays the trip. Therefore, the best option when a tire blowout occurs is to replace the spare tire in time. In order to ensure the smooth operation of tire changing, the vehicle body needs to be lifted. The current toolbox does not have the function of lifting the vehicle body, so it is necessary to carry additional tools such as jacks to complete the operation.

[0019] An application method of a vehicle lever-type multifunctional maintenance tool box, using the above-mentioned vehicle lever-type multifunctional maintenance tool box, comprises the following steps:

[0020] S1: When performing simple repairs on a car, the user picks up the tool box by the handle and moves the box to the car to be repaired, then places the box on the ground, opens the buckle to open the box cover, and then takes out the corresponding tools from the tool area to repair the car body;

[0021] S2: When changing tires on a car, after opening the box cover, place the end of the box away from the box cover under the end of the car body to be lifted, and align the contact plate with the metal rib under that side of the car body;

[0022] S3: Choose a side that is convenient for standing, turn the extension plate on the L-shaped rod on that side of the box downward until it is level with the L-shaped rod, then step on the extension plate with your feet to drive the connecting frame downward through the L-shaped rod;

[0023] S4: When the connecting frame moves downward, it drives the two push rods 2 to move downward at the same time, and the hydraulic oil in the small oil cylinder is input into the large oil cylinder through the one-way delivery pipe. The pressure at the bottom of the large oil cylinder increases, which drives the push rod 1 to move upward, causing the fixed rod to move upward at the same time. At this time, the fixed rod drives the two swing frames and the two support frames to move closer to each other and drive the contact plate to move upward;

[0024] S5: After the extension plate is stepped on to the lowest position, the extension plate is released and moved upward and reset by the elastic force of the spring. During this process, the connecting frame drives the two push rods to move upward and reset, and the hydraulic oil in the oil storage chamber is pumped into the small oil cylinder through the one-way oil inlet pipe. Then, the extension plate is stepped on again to pump the hydraulic oil in the small oil cylinder into the large oil cylinder again. The extension plate is stepped on repeatedly until the contact plate lifts the vehicle body to a suitable height so that the tire on that side is separated from the ground;

[0025] S6: Take out ratchet wrenches and other tools from the tool area to change the tire. After the tire is changed, twist the blocking rod to release the sealing effect on the pressure relief pipe. At this time, the hydraulic oil at the bottom of the large oil cylinder flows into the oil storage chamber, and the contact plate moves down to reset. Then, the extension plate is rotated to reset, the blocking rod is tightened again, and the box cover is closed;

[0026] S7: the operation of disengaging the tire after it is stuck in the mud pit. When the tire is stuck in the mud pit, open the box cover and align the contact plate with the tire stuck in the mud pit, then repeat steps S3-S5 until the contact plate moves to the highest position. At this time, the lower end of the tire is at the same horizontal height as the upper surface of the box body, and in the process of the contact plate about to reach the highest point, the slider will push the cross bar located in the slide groove to move upward, and the meshing effect of the fixed rack and the fixed gear will cause the side plate to rotate outward from the accommodating groove to a horizontal state with the upper surface of the box body. During the rotation of the side plate, the contact block will contact the bottom of the load-bearing support plate and deflect under the action of resistance and the elastic force of the torsion spring. After continuing to rotate, the contact block moves from the bottom of the load-bearing support plate to the upper end of the load-bearing support plate with the side plate, and the load-bearing support plate supports the bottom of the two contact blocks as the fixed block moves upward. At this time, the two side plates and the two contact blocks form a path for the tire to travel. After that, the driver can place a wooden board or steel plate between the lower end of the tire and the box body, and then start the car to let the tire drive out of the mud pit.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] 1: The tool box sets the lever lifting part inside the box body, so that the user can directly lift the car through the tool box without carrying a jack, which effectively improves the overall convenience and functionality.

[0029] 2: The toolbox uses the cooperation of the lever lifting part and the hydraulic drive part, and the car can be lifted by pedaling, which greatly reduces the difficulty of operation and does not require the user to bend over to operate. It also effectively increases the maximum load-bearing weight, ensures stability when lifting the car, and avoids problems such as side slipping or sudden unloading of force that may cause damage to the equipment.

[0030] 3: The lever jacking part used in this toolbox has a more stable structure and more fulcrums than the existing mechanical jack, which can ensure the stable horizontal jacking of the car, and also improve the stability and supporting effect of the overall structure, making it safer and more reliable to use.

[0031] In summary, the tool box of the present invention can directly lift the car by stepping on it, without the need to carry an additional jack, and is more convenient to use. At the same time, the overall load-bearing weight and stability are better, and the car body can be effectively and stably lifted and supported, making it safer and more reliable to use.

[0056] An application method of a vehicle lever-type multifunctional maintenance tool box, using the above-mentioned vehicle lever-type multifunctional maintenance tool box, comprises the following steps:

[0057] S1: When performing simple repairs on a car, the user picks up the tool box by the handle and moves the box body 1 to the car to be repaired, then places the box body 1 on the ground, opens the buckle to open the box cover 2, and then takes out the corresponding tools from the tool area to repair the car body;

[0058] S2: When the tire of the car is changed and repaired, after the box cover 2 is opened, the end of the box body 1 away from the box cover 2 is put under the end of the car body to be lifted, and the contact plate 8 is aligned with the metal rib under the side of the car body;

[0059] S3: Select a side that is convenient for standing, rotate the extension plate 30 on the L-shaped rod 26 on the side of the box body 1 downward to keep it level with the L-shaped rod 26, and then step on the extension plate 30 with your feet to drive the connecting frame 25 to move downward through the L-shaped rod 26;

[0060] S4: When the connecting frame 25 moves downward, it drives the two push rods 19 to move downward at the same time, and the hydraulic oil in the small oil cylinder 18 is input into the large oil cylinder 16 through the one-way delivery pipe 22. The pressure at the bottom of the large oil cylinder 16 increases, which drives the push rod 17 to move upward, so that the fixed rod 11 moves upward at the same time. At this time, the fixed rod 11 drives the two swing frames 5 and the two support frames 6 to move closer to each other and drive the contact plate 8 to move upward;

[0061] S5: After the extension plate 30 is stepped on to the lowest position, the extension plate 30 is released and the elastic force of the spring 29 is used to move it upward and reset. In this process, the connecting frame 25 drives the two push rods 19 to move upward and reset, and the hydraulic oil in the oil storage chamber 20 is pumped into the small oil cylinder 18 through the one-way oil inlet pipe 21. Then, the extension plate 30 is stepped on again to pump the hydraulic oil in the small oil cylinder 18 into the large oil cylinder 16 again. The extension plate 30 is stepped on repeatedly until the contact plate 8 lifts the vehicle body to a suitable height so that the tire on this side is separated from the ground.

[0062] S6: Take out ratchet wrenches and other tools from the tool area to change the tire. After the tire is changed, twist the blocking rod 24 to release its sealing effect on the pressure relief pipe 23. At this time, the hydraulic oil at the bottom of the large oil cylinder 16 flows into the oil storage chamber 20, and the contact plate 8 moves down to reset. Then, the extension plate 30 is rotated to reset, the blocking rod 24 is tightened again, and the box cover 2 is closed.

[0063] S7: Operation of disengaging the tire after it is stuck in a mud pit. When the tire is stuck in a mud pit, open the box cover 2 and align the contact plate 8 with the tire stuck in the mud pit. Then repeat the steps S3-S5 until the contact plate 8 moves to the highest position. At this time, the lower end of the tire is at the same level as the upper surface of the box body 1. When the contact plate 8 is about to reach the highest point, the slider 10 pushes the cross bar 39 in the slide groove 9 to move upward. Through the meshing effect of the fixed rack 41 and the fixed gear 38, the side plate 33 is rotated outward from the receiving groove 32 to a level state with the upper surface of the box body 1. During the rotation of the side plate 33, the contact block 35 will contact the bottom of the load-bearing support plate 34 and deflect under the action of resistance and the elastic force of the torsion spring. After continuing to rotate, the contact block 35 moves from the bottom of the load-bearing support plate 34 to the upper end of the load-bearing support plate 34 along with the side plate 33.
