Description

Technical Field

[0001] The utility model relates to an electric vehicle auxiliary frame, in particular to an auxiliary frame structure for assembling a lead-acid battery. Background Art

[0002] Conventional lithium batteries are placed under the vehicle's driver's seat. Due to the limited space and high position under the seat, the heavier battery not only increases the vehicle's center of gravity but also limits the battery capacity. In addition, the existing frame has been converted to a lithium battery design and cannot be converted to lead-acid batteries, resulting in a narrower range of vehicles. If a lead-acid battery is directly installed in the original lithium battery position, the cruising range will be greatly reduced. If the frame is modified to expand the battery compartment, the entire production line needs to be modified, which will greatly increase the company's production costs. Summary of the Invention

[0003] In response to the problems existing in the above-mentioned prior art, the present invention provides a subframe structure for assembling lead-acid batteries, which can increase the lead-acid battery loading capacity without changing the existing production line, effectively improving the applicability of the vehicle and reducing the cost of using the vehicle.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a subframe structure for assembling a lead-acid battery, comprising a condenser bracket, a lead-acid battery support portion, a lead-acid battery supporting frame, a battery hook frame, a frame balancing connecting plate, a swing arm bracket and a steering gear bracket. The subframe also comprises a subframe connecting beam and a subframe side beam. The two ends of the subframe connecting beam are bent downward to connect the front portions of the two subframe side beams. The steering gear bracket is fixedly mounted on the middle sections of the two subframe side beams, and the swing arm bracket is fixedly mounted on the end portion of the steering gear bracket. The lead-acid battery support portion is fixedly mounted on the upper portion of the subframe connecting beam and the steering gear bracket of the subframe. Two condenser brackets are mounted in parallel on the front portion of the subframe connecting beam, and a compressor bracket is welded and mounted on the upper portion of the middle section of the subframe side beam.

[0005] In addition, the subframe structure for assembling a lead-acid battery according to the above embodiment of the present invention may also have the following additional technical features:

[0006] As a further improvement scheme of the present utility model, the lead-acid battery support part includes a lead-acid battery supporting frame, a battery hook frame and a frame balancing connecting plate. The lead-acid battery supporting frame is connected to the subframe connecting beam and the steering gear bracket through the frame balancing connecting plate at the front and rear, and the battery hook frame is welded and installed on both sides of the lead-acid battery supporting frame.

[0007] As a further improvement of the present invention, the auxiliary frame connecting beam, the auxiliary frame side beam and the steering gear bracket are all made by welding, bending and cutting hollow circular tubes.

[0008] As a further improvement of the present invention, the two sub-frame side beams of the sub-frame are formed with a collapse recess extending in a direction perpendicular to the longitudinal direction of the vehicle.

[0009] As a further improvement of the present invention, a battery protection plate is provided at the lower portion of the lead-acid battery supporting frame.

[0010] Through the above solution, the present invention has at least the following advantages: compared with conventional frames, by adding a lead-acid battery support part, a battery loading area is added to the vehicle, so that the vehicle can select the corresponding battery according to customer needs, and the lead-acid battery loading area can be increased without changing the existing production line, which can effectively improve the applicability of the vehicle and reduce the cost of vehicle use.
