Automobile inflatable jack

Abstract

The invention discloses an automobile inflation jack, belongs to the technical field of automobile parts, and aims to solve the technical problems that when a spare tire of an automobile is replaced, a jack is time-consuming and labor-consuming, and the automobile and hands are easy to hurt, and the key point of the technical scheme for solving the problems is that a jack capable of being inflated or deflated is manufactured; the device is mainly used for helping a driver to replace the automobile spare tire, saves time and labor and does not hurt hands.

Description

[0001] Technical field: The technical field to which the technical solution claimed for protection in this application belongs is the field of automotive parts.

[0002] Background technology: Common car jacks on the market include scissor screw jacks and ordinary screw jacks. Scissor screw jacks are usually used for general passenger cars, while ordinary screw jacks are suitable for SUVs and pickup trucks. These jacks are made of metal, which is time-consuming and labor-intensive to use and can easily damage the car and hands.

[0003] Invention content: The technical problem to be solved by the present application is that the use of a vehicle jack is time-consuming and labor-intensive and can easily damage the car and the hands. The technical solution adopted to solve this problem is to use a rubber material to make an inflatable cylinder, a rectangular parallelepiped, a cube, etc., and put a coat made of cloth or plastic on the outside of the cylinder, the rectangular parallelepiped, the cube, etc. Compared with the prior art, the beneficial effect is that it saves time and labor when used, does not hurt the hands, and does not damage the car.

[0004] Description of the drawings: Figure 1 It is a diagram of a left rear wheel supporting jack of a car (sedan), in which: 1 is a car; 2 is a jack; 3 is an inflation valve of the jack (including an exhaust valve, the inflation valve and the exhaust valve are integrated); 4 is a manual deflation valve of the jack; 5 is an outer layer of the jack.

[0005] Specific implementation method: A jack (carried on the vehicle or carried with the vehicle) used when replacing (unloading and installing) a spare tire of a vehicle (including electric vehicles and hybrid vehicles), including:

[0006] 1 Use rubber material (or bicycle inner tube material or air mattress material or air cushion material) to make a cylinder [diameter 10-20 cm, height 2-20 cm higher than the height from the automobile beam (the automobile beam is specially used for the position of the jack, the same below) to the ground or determined by the height from the automobile beam to the ground] or a cuboid or cube with a rectangular (the length of the rectangle is about 20 cm, the width is about 10 cm) or square (the side length of the square is 10-15 cm) cross-sectional area (the height of the cuboid or cube is 2-20 cm higher than the height from the automobile beam to the ground or determined by the height from the automobile beam to the ground).

[0007] 2 The inside of the jack is made hollow and is used for inflation or deflating. The surrounding is sealed or airtight, and there is no air leakage after inflation.

[0008] 3. Install an inflation valve (including an exhaust valve, which also serves as an exhaust valve, i.e., the inflation valve and the exhaust valve are integrated) at a suitable height or in the middle of the jack.

[0009] 4Install a manual deflation valve next to the inflation valve.

[0010] 5. A jacket made of cloth or plastic material of the same shape and appropriate size is made and put on the outside of the above 1, 2, 3, and 4 jacks. The upper and lower ends of the jacket can be sealed or open. The height is adapted to the jack or determined by the height from the vehicle beam to the ground. Two holes of appropriate size are left at the positions corresponding to the inflation valve and the manual deflation valve of the jack.

[0011] 6. Equipped with a rechargeable electric pump that can automatically inflate or deflat.

[0012] 7. How to use: Park the car in a safe area according to the law, turn off the engine, and pull the handbrake. Use bricks to block the other three car tires to prevent the car from slipping. After loosening the nuts of the unloaded tires with a wrench, use a jack at the jack-dedicated position under the car next to the unloaded tire (if the jack has a rectangular or square cross-sectional area, it must be rectangular or square and jacked up in the same direction as the car). Use an electric pump to inflate and jack up the tire to a suitable position above the ground. Continue to unscrew the nuts of the unloaded tire by hand, unload the unloaded tire, install the spare tire, and tighten the nuts diagonally by hand until it cannot be turned anymore. Use an electric pump to pump air out of the jack or open the manual deflation valve to deflate it, then take out the jack, and tighten the nuts on the installed spare tire diagonally with a wrench. Put away the unloaded tire, wrench, jack, and electric pump on the ground, put them in the trunk of the car, and clean the bricks next to the tire.

Claims

1. Use rubber material (or bicycle inner tube material or air mattress material or air cushion material) to make a cylinder [diameter 10-20 cm, height 2-20 cm higher than the height from the automobile beam (the automobile beam is specially used for the position of the jack, the same below) to the ground or determined by the height from the automobile beam to the ground] or a rectangular or cube with a cross-sectional area of ​​a rectangle (the length of the rectangle is about 20 cm, the width is about 10 cm) or a square (the side length of the square is 10-15 cm) (the height of the rectangular or cube is 2-20 cm higher than the height from the automobile beam to the ground or determined by the height from the automobile beam to the ground).

2. The inside of the jack is made hollow, which is used for inflation or deflating. The surrounding is sealed or airtight, and there is no air leakage after inflation.
