Electric car mover with dual self-locking

Abstract

The invention discloses an electric car mover with dual self-locking. The electric car mover comprises a bottom frame, a front holding clamp structure and a seven-connecting-rod lifting mechanism, wherein walking universal wheels are arranged below the bottom frame; the front holding clamp structure is of a stepped structure fixed at the inner side of a front frame; the seven-connecting-rod lifting mechanism is arranged at the inner side of a rear frame and comprises a large hinged support fixed on the rear frame, a roller parallel to the rear frame, and two seven-connecting-rod telescopic units hinged to the two ends of the roller; a pedal is hinged to the large hinged support and optical axes are arranged on two sides of the pedal; each seven-connecting-rod telescopic unit comprises a rotating rod, a self-locking swinging connecting rod set, a self-locking lower connecting rod set, a long connecting rod and a propelling connecting rod which are hinged to each other and are self-locked in the telescopic state respectively; the optical axes are driven to rotate through stepping on the pedal, and the seven-connecting-rod telescopic units are driven to stretch, so that lifting and parking of electric wheels are realized. According to the electric car mover, the movement in any direction and any distance can be effectively realized when the electric car is got and the wheels are clamped and fixed, and management of the electric car is greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of heavy-duty machinery, in particular to a dual self-locking electric vehicle shifter. Background technique [0002] With the rapid increase in the number of electric vehicles in urban communities, electric vehicle parking devices will become an important way to solve the problem of urban parking difficulties. There are mainly three types of electric vehicle handling and parking at present: three-dimensional garage type, hydraulic lifting type and mechanical positioning pin type. [0003] The three-dimensional garage type is only suitable for high-end residential areas with a large number of electric vehicles. Due to its high price and low space utilization rate, it is not easy to promote. [0004] The hydraulic lifting type can be lifted and lowered arbitrarily within the range, but the application of hydraulic pressure increases the cost and there is also the risk of hydraulic leakage. [0005] The mech...

AI Technical Summary

Problems solved by technology

[0003] The three-dimensional garage type is only suitable for high-end residential areas with a large number of electric vehicles. Due to its high price and low space utilization rate, it is not easy to promote

[0004] The hydraulic lifting type can be lifted and lowered arbitrarily within the range, but the application of hydraulic pressure increases the cost and there is also the risk of hydraulic leakage

[0005] The mechanical positioning pin type has low cost and reliable lifting, but each operation needs to squat up and down and insert and pull out the pin, which is cumbersome to operate

[0006] According to the search, there are currently existing vehicle carriers, such as the Chinese patent No. 201621078116.8 named "An Emergency Translation Device for Automobiles". The lifting mechanism of this patent uses a gear set for lifting, and the installation accuracy is high. The ratchet mechanism is used for locking, and the reversing disc needs to be moved to release the self-locking, which increases the difficulty for the final realization of the operation
