Storage battery frame structure for commercial vehicle

Abstract

The invention relates to the technical field of vehicle structures, and discloses a commercial vehicle storage battery frame structure which comprises a base, a storage battery fixedly arranged on the base and a cover cap covering the storage battery, the cover cap is fixedly connected with the base, the base is arranged at the position of the rear wall of a cab of a vehicle frame, and the bottom of the base is fixedly connected with a transition support. The base is fixedly arranged on a frame longitudinal beam at the rear wall of a cab through a transition support, and the base extends and is fixed in the width direction of a vehicle. The base is arranged at the position of the cab rear wall, the arrangement space of the cab rear wall is fully utilized, and the storage battery frame is located on the upper side of the frame and does not occupy the arrangement space of the oil tank, so that the volume of the oil tank is increased; the cab rear wall is located in the middle of the whole vehicle, vibration is small, the load borne by the storage battery is reduced, and the structural reliability of the storage battery frame is improved; the base is fixedly arranged on the frame longitudinal beam through the transition support to form a simply supported beam structure, the installation structure of the storage battery frame is simplified, and light weight of the storage battery frame structure is achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle structures, in particular to a battery frame structure for commercial vehicles. Background technique [0002] In modern society, heavy-duty trucks have higher and higher requirements for cruising range. With the upgrade of vehicle emission requirements, different manufacturers have simultaneously upgraded the fuel tank volume of heavy-duty trucks to improve the cruising range of heavy-duty trucks. However, when the volume of the fuel tank increases, the layout space of the fuel tank can be increased by adjusting the arrangement position of other parts such as the battery frame without increasing the wheelbase of the whole vehicle. [0003] For example, the patent with the authorization announcement number of CN110816449B discloses a vertical double-layer battery frame assembly. Two battery mounting plates are arranged in parallel along the vertical direction, and a vertical double-layer battery fr...

AI Technical Summary

Problems solved by technology

The above method can improve the layout space of the fuel tank, but the rear end of the frame has a large vibration range, and the battery frame has higher requirements on the reliability and shock absorption of the battery frame after it moves to the rear end, and the weight of the battery frame is larger, its reliability The risk is high, so it is necessary to increase the suspension system to attenuate the vibration at the rear of the frame, the structure is complex and the layout cost is high
