Disclosure of Invention

The invention aims to provide an integrated lifting lug structure which is convenient to install and simple and firm in structure and enables a plate spring and a battery pack of an electric automobile to be fixed on a frame.

In order to solve the technical problem, the invention provides an integrated lifting lug structure for fixing a plate spring and a battery pack on a frame. The plate spring lifting lug comprises an integrally bent and formed plate spring lifting lug main body, wherein the plate spring lifting lug main body is in a shape like a Chinese character 'ji', metal plates extending out of two sides can be riveted with an automobile longitudinal beam, riveting holes are reserved in the plate spring lifting lug main body, and a lifting wall is arranged below the plate spring lifting lug main body. Including bending the integrative battery package lug of welding, battery package lug presents anti-U shape, and battery package lug leaves strengthening rib and riveting hole. The hanging wall in the two directions is mutually perpendicular, pin shafts are reserved on the hanging walls in the two directions and are respectively connected and fixed with the leaf spring and the battery pack, and hanging holes are formed in the hanging walls. The battery package lug is bent as an organic whole with leaf spring sharing panel beating and is added the welding, closes two kinds of lugs as an organic whole, is equipped with the riveting hole, reserves the part of bending and increases structural strength.

As an optimized technical scheme, the structure fixes the plate spring and the battery on the frame to form an integrated lifting lug, so that the force borne by the battery pack lifting lug is completely transferred to the plate spring lifting lug and then fixed on the automobile longitudinal beam, and the structure of the integrated lifting lug is convenient, simple and firmer, and the strength is increased. Time and operation steps are saved when the battery pack is installed, and production cost is reduced.

According to the preferable technical scheme, the structural welding part is welded in a tenon-and-mortise structure, so that welding is firm, and the plate spring lifting lug and the battery pack lifting lug are fixedly connected through a pin shaft.

As the preferred technical scheme, the riveting part and the side surface and the bottom surface of the automobile longitudinal beam are respectively provided with a connecting part, so that the lifting lug of the integrated structure is uniformly stressed.

Because the technical scheme is adopted, the integrated lug structure for fixing the plate spring and the battery pack on the frame comprises the integrally bent and formed plate spring lug main body, the lug main body is in a shape of a plurality of pieces, metal plates extending out of two sides can be riveted with the automobile longitudinal beam, riveting holes are reserved in the lug main body, and the hanging wall is arranged below the plate spring lug main body. Also including bending the integrative battery package lug of welding, the battery package lug presents anti-U shape, and battery package lug leaves strengthening rib and riveting hole. Hollow hanging walls are arranged in the directions parallel to and perpendicular to the vehicle frame, pin shafts are reserved on the hollow hanging walls, the hollow hanging walls are respectively connected and fixed with the leaf springs and the battery packs, and hanging holes are formed in the hanging walls. The battery package lug is bent as an organic whole with leaf spring sharing panel beating and is added the welding, closes two kinds of lugs as an organic whole, is equipped with the riveting hole, reserves the part of bending and increases structural strength. The invention has the advantages that: the integrated lifting lug structure for fixing the plate spring and the battery pack on the frame comprises the frame, the plate spring, the battery pack and the integrated lifting lug. The plate spring and the battery pack are fixed on the frame through the integrated lifting lugs and are provided with three fixing positions, namely the battery pack lifting lug, the plate spring lifting lug and the frame. The integral lifting lug structure is formed by bending, stretching, cutting, punching, welding and the like, wherein the welding is tenon-and-mortise welding, the structure is firm, and the riveting part is arranged on the side surface and the bottom surface of the longitudinal beam of the frame, so that the lifting lug is uniformly stressed. The bearing function of the plate spring lifting lug and the battery pack lifting lug is met, the installation is convenient, the lifting lugs are changed into an integrated structure from two lifting lugs, the cost is reduced, and the reliability of the battery pack is also improved.
