Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to a spliced ​​electric vehicle frame. Background Art

[0002] The frame is one of the main components of an electric vehicle, and its quality is directly related to the personal safety of users. The structural form of the frame should be able to meet the needs of its function (assembly, etc.), performance (rigidity, strength, etc.) and commerciality. The importance of the frame is equivalent to the skeleton of the human body. The installation of all parts of the electric vehicle is based on the frame, which plays a decisive role in the safety of the electric vehicle.

[0003] When an electric vehicle is driving, the frame mainly uses springs on both sides to absorb shock. However, rainwater and mud on the roadside will adhere to the surface of the spring shock absorbers when the electric vehicle is driving. The spring shock absorbers lack a cleaning mechanism, which will cause corrosion of the springs and hydraulic components. In addition, the frame is an integrated structure, and the commonly used seat components will corrode faster than other components after long-term use. It is difficult to disassemble and replace some commonly used components, which will affect the difficulty of frame maintenance. Summary of the invention

[0004] The purpose of the utility model is to provide a spliced ​​electric vehicle frame to solve the above-mentioned defects caused by the prior art.

[0005] A spliced ​​electric vehicle frame includes a front beam frame and a flat fork bridge tube, a head tube is welded and fixed on one side of the front beam frame, side baffles are symmetrically connected to the left and right sides of the front beam frame, a disassembly mechanism is arranged directly above the front beam frame, one end of the flat fork bridge tube is symmetrically welded to the rear end of the front beam frame, the disassembly mechanism is used to disassemble and replace the bracket for the seat cushion, so as to improve the efficiency of material replacement and splicing, a wheel slot is penetrated through one side of the flat fork bridge tube, a shock absorbing mechanism is arranged on the other side of the disassembly mechanism, the shock absorbing mechanism performs shock absorbing treatment on the bottom end of the seat, and cleans the mud attached to the surface of the equipment to prevent the mud from getting stuck on the surface of the shock absorbing mechanism.

[0006] Preferably, the disassembly mechanism includes a seat tube, a quick-release base, a seat cushion support plate, positioning holes and fasteners, the seat tube is arranged directly above the front beam frame, the outer side of the seat tube is penetrated and connected with fasteners, the outer side of the seat tube is connected to the quick-release base, the other side of the quick-release base is welded with a seat cushion support plate, the outer side of the quick-release base is penetrated with positioning holes, and one side of the seat tube is welded with one end of two groups of rear axle support frames.

[0007] Preferably, the seat cushion support plate is connected to the top end of the seat tube via a quick-release base arranged at the bottom end.

[0008] Preferably, the shock absorbing mechanism includes a buffer shock absorber, a rear axle support frame, a vertical guide rod, an outer cleaning ring and a soft brush, the top of the buffer shock absorber is connected to the bottom end of the rear axle support frame, the bottom end of the buffer shock absorber is connected to the top of the flat fork bridge tube, the outer side of the buffer shock absorber is annularly distributed with vertical guide rods, the outer side of the vertical guide rod is penetrated by an outer cleaning ring, and the inner end of the outer cleaning ring is connected to a soft brush.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. During use, the seat support plate and the top of the seat tube are connected through the quick-release base. When part of the seat tube or the seat support plate is severely corroded, the seat tube can be removed from the electric vehicle frame, and then the quick-release base and the top of the seat tube can be removed through the positioning hole, thereby partially replacing the frame of the small electric vehicle and reducing the difficulty of equipment maintenance.

[0013] 2. During the driving of an electric vehicle, mud will accumulate on the surface of the buffer shock absorber. By pulling the outer cleaning ring and using the outer cleaning ring and a soft brush to lift and lower it vertically, the surface of the buffer shock absorber can be scrubbed and cleaned with a soft brush to prevent mud from entering the buffer shock absorber, which may cause the buffer shock absorber to get stuck or the equipment to corrode. This can also prevent liquids from corroding the equipment for a long time, which may affect the overall stability of the electric vehicle during operation. BRIEF DESCRIPTION OF THE DRAWINGS
