Lifter for vehicle

Abstract

The present invention relates to a lifter for a vehicle, comprising: a first supporting unit provided flatwise to support the lower side of a vehicle; a second supporting unit separated from the first supporting unit and provided flatwise to support the ground; and an expansion unit, which comprises a connective part, for connecting the first supporting unit and the second supporting unit to each other and expanding when a fluid is supplied to a sealed space formed therein.

Description

technical field [0001] The present invention relates to a vehicle lifter, and more specifically, to a vehicle lifter that can be easily installed regardless of various road surface conditions or vehicle positions, and can maintain a stable installed state. Background technique [0002] The vehicle lifter (lifter) is a mechanism that uses gears, screws or hydraulic pressure to lift the vehicle body vertically. In general, it is usually installed on the vehicle to replace the tires of the vehicle or to repair and overhaul the lower part of the vehicle. trunk. [0003] Moreover, the following method is also used: compared with ordinary mechanical lifters, the user installs a dedicated motor for the lifter using the vehicle power supply for more convenient use, and uses the power of the motor to automatically run the lifter. [0004] This method of using the motor can provide convenience in the event of a tire blowout or other vehicle maintenance, and there is no need to use an...

AI Technical Summary

Problems solved by technology

[0005] However, this conventional vehicle is not suitable for uneven roads that have not been flattened, or when a slope begins such as an uphill or a downhill section, or when the vehicle is stuck on an overspeed prevention shoulder. There is a problem that it is difficult to set the space between the ground and the underside of the vehicle with the lifter

[0006] That is, in the case of installing the lifter on an uneven uneven road surface, the lower end surface of the lifter can only form a small contact surface with the ground. Moving while lifting the car, there is a problem of damaging the car body or injuring the user who operates the lifter

[0007] And, when it needs to be used in the section where the slope starts, such as uphill or downhill, that is, when the vehicle body and the road surface are not flat with each other, only one of the lower end and the upper end of the lifter can be in contact with the ground or the lower part of the vehicle. Creates a small contact surface and therefore, as in the case of installation on uneven road surfaces, sets the lifter in an unstable manner, thus having the problem of moving the lifter during lifting of the vehicle

[0008] Also, in the case where the vehicle is located on the upper side of a protruding portion such as an overspeed prevention shoulder, there is a disadvantage that a lifter cannot be installed due to the narrow space between the ground and the underside of the vehicle
