Background technique

With the development and progress of society, people's living standards continue to improve. As an environmentally friendly travel industry, electric vehicles have experienced more than ten years of development and have become the most common means of transportation in people's lives. Battery-driven car is favored by people with its cheap, easy and labor-saving operation. However, electric vehicles also have the disadvantage of heavy weight. In daily use, when the electric car needs to be pushed indoors for charging or parked on the sidewalk, it is usually necessary to push the car up one or more steps, and the height of the steps brings great trouble to the person pushing the electric car. Mostly used in the city now is to make slopes with cement and iron plates on both sides of the steps, but these devices have problems such as being unattractive and unable to be carried. When there is no slope, it will be very laborious to push the electric car up the steps.

Utility model content

The purpose of the utility model is to provide a portable extendable step-up device to solve the above problems.

In order to achieve the above object, the utility model adopts the following technical solutions:

A portable extendable step-up device, comprising an upper outer plate, a lower outer plate, an inner plate, a rack and a ratchet; side plates are fixed and vertically arranged on both sides of the lower surface of the upper outer plate, and the top of the side plate is arranged on the bottom of the lower outer plate Surface; the upper outer plate, lower outer plate and side plates form a hollow double-layer plate structure; the inner plate is arranged in the double-layer plate structure, and the rack is fixed along one side of the inner plate, and the inner plate can be placed on the double-layer plate Movement within the structure; the ratchet is arranged between the upper outer plate and the lower outer plate, and the ratchet is engaged with the rack.

Further, bearings are arranged symmetrically on opposite surfaces of the upper outer plate and the lower outer plate, a shaft is arranged between the two bearings, and the ratchet is fixedly arranged on the shaft.

Further, a rocker is fixed vertically on the shaft, and the direction of the rocker is away from the rack.

Further, a ratchet is hinged on the rocker, and the end of the ratchet is inserted into the groove of the ratchet; the ratchet is provided with a torsion spring for making the ratchet contact with the ratchet.

Further, the upper surface of the lower outer plate is provided with guide grooves, the lower surface of the inner plate is provided with guide strips, and the guide strips are arranged in the guide grooves.

Further, a slope is provided at the end of the inner panel that moves outward; a slope is provided at the end of the upper outer panel; and a handle is provided on the side of the upper outer panel.

Compared with the prior art, the utility model has the following technical effects:

The utility model cooperates with the upper outer plate, the lower outer plate and the inner plate. When the electric vehicle goes up the steps, the rocker is moved to move the inner plate out to form a slope that is convenient for the electric vehicle to walk on, which solves the problem of the electric vehicle going up the steps. It can be extended to different distances for adaptive adjustment according to the number of steps, and the handle is fixed on the side, which fully realizes simple structure, high strength, convenient adjustment and installation, and is easy to carry.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

Please refer to Fig. 1-Fig. 3, a portable extendable step-up device, including an upper outer plate 1, a lower outer plate 2, an inner plate 3, a rack 4 and a ratchet 5; the lower surface of the upper outer plate 1 is fixed on both sides Side panels are vertically arranged, and the top of the side panels is set on the surface of the lower outer panel 2; the upper outer panel 1, the lower outer panel 2 and the side panels form a hollow double-layer panel structure; the inner panel 3 is arranged in the double-layer panel structure, and the rack 4 is fixedly arranged along one side of the inner panel 3, and the inner panel 3 can move in the double-layer panel structure; the ratchet 5 is arranged between the upper outer panel 1 and the lower outer panel 2, and the ratchet 5 is engaged with the rack 4.

Bearings are arranged symmetrically on opposite surfaces of the upper outer plate 1 and the lower outer plate 2 , and a shaft 8 is arranged between the two bearings, and the ratchet 5 is fixedly arranged on the shaft 8 .

A rocker 6 is fixed vertically on the shaft 8 , and the direction of the rocker 6 is far away from the rack 4 .

A ratchet 7 is hinged on the rocking bar 6, and the end of the ratchet 7 is inserted in the groove of the ratchet 5;

The upper surface of the lower outer plate 2 is provided with a guide groove, and the lower surface of the inner plate 3 is provided with a guide strip, and the guide strip is arranged in the guide groove.

The end of the inner panel 3 that moves outward is provided with a slope; the end of the upper outer panel is provided with a slope; the side of the upper outer panel 1 is provided with a handle.

When using the utility model, first judge the elongation length of the required inner plate according to the height of the steps, and shake the rocker 6 forward, thereby driving the ratchet mechanism 5 to rotate forward, so that the rack 4 meshing with the ratchet 5 drives The inner panel 3 protrudes outward. When the required length is reached, stop rotating the rocker 6 to keep the overall length constant and ensure the use. When the inner panel 3 needs to be packed up, turn the ratchet 7 outward so that it does not contact the ratchet mechanism 5, then The inner panel 3 can be folded up manually to complete the use of the device of the present utility model.
