Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric vehicle frame technology, and in particular to a frame for mounting multiple batteries. Background Technology
[0002] The electric vehicle frame is the main supporting structure of an electric vehicle. The main frame is welded from steel pipes or aluminum alloy materials, forming the basic outline and overall structure of the electric vehicle. It includes the uprights at the front, the beam connecting the front and rear wheels, and the supporting structure under the rear seat. The design, materials, and manufacturing process of the electric vehicle frame directly affect the performance, safety, and service life of the electric vehicle.
[0003] A search revealed Chinese patent publication number CN219969898U, which discloses a frame for a two-wheeled electric vehicle, including a lower frame, a rear wheel frame, side support frames, lower support plates, a frame-type frame, a rear frame, and a reinforced side frame body. The rear frame is fixedly connected to the rear end of the lower frame. Two lower support plates are symmetrically arranged at the connection between the rear frame and the lower frame. A reinforced side frame body is fixedly installed on one side of the rear frame, and multiple welding points are provided between the reinforced side frame body and the rear frame. The utility model provides a rear frame on one side of the lower frame, with a lower support plate at the connection between the rear frame and the lower frame. A welding seat is provided on the inner side of the lower support plate, and a reinforcing side frame is welded to one end of the welding seat. The reinforcing side frame is located on one side of the rear frame, forming a double frame structure together with the rear frame. This effectively strengthens the overall frame, providing better strength and pressure resistance during support. However, this type of electric vehicle frame can only accommodate one battery, resulting in poor range efficiency and failing to meet usage requirements. Utility Model Content
