External foldable lifting mechanism for vehicle maintenance service vehicle

Abstract

The invention provides an external foldable lifting mechanism for a vehicle maintenance service vehicle. The external foldable lifting mechanism is characterized by comprising a connecting seat; a base is in threaded connection with the connecting seat; two landing legs are arranged at the rear end of the base, the front ends of the landing legs are hinged to the base, and the two landing legs are fixedly connected through a first cross rod; the front ends of main arms are hinged to the base, and the main arms are fixedly connected through a second cross rod; the front ends of auxiliary arms are hinged to the base; a lifting platform is parallel to the bottom faces of the landing legs, and hinged to the rear ends of the main arms and the rear ends of the auxiliary arms at the same time; two pairs of safety supporting rods are arranged on the outer sides of the two landing legs respectively, the upper ends of the safety supporting rods are fixedly connected with the main arms, and the lower ends of the safety supporting rods are fixedly connected with the landing legs; a cylinder body of each landing leg oil cylinder is hinged to the base, and a piston rod of each landing leg oil cylinder is hinged to the first cross rod; a cylinder body of a lifting oil cylinder is hinged to the first cross rod, and a piston rod of the lifting oil cylinder is hinged to the second cross rod; and landing leg safety pins penetrate the landing legs when the landing legs are folded, are arranged in the base in a penetrating manner and are fixedly connected with the base, landing leg discs are arranged below the rear supporting faces of the rear ends of the landing legs and fixedly connected with the landing legs, small battens are arranged below the landing leg discs, and large battens are arranged below the front supporting faces of the landing legs.

Description

technical field [0001] The invention relates to automobile maintenance, in particular to an automobile maintenance service vehicle, which is an external foldable lifting mechanism for the vehicle maintenance service vehicle. Background technique [0002] With the rapid increase in the number of family cars, the workload of car maintenance and repair is increasing. Over the past few years, a new kind of service car-multifunctional vehicle mobile service car has emerged at the historic moment. The car not only has the function of car maintenance and repair, but also has the characteristics of flexible and fast service, so it is very popular among users. The service car generally has a car lifting function, and its lifting tools adopt various jacks. Such as: car horizontal jack, car hand jack, car electric scissor jack. Although these tools are easy to use, the lifting height is only 300-500mm. In order to increase the lifting height and expand the scope of maintenance, som...

Problems solved by technology

Due to the heavy weight, a special retractable mechanism needs to be designed, so it takes up a lot of space and seriously affects the placement of other maintenance equipment and tools.

Due to the above reasons, so far, there is no practical application and literature report of a multifunctional vehicle mobile service vehicle with a lifting height of 1.2 meters and a relatively complete maintenance equipment and tools on the market.
