Description

Technical Field

[0001] This utility model relates to the field of two-wheeled vehicle technology, and in particular to a two-wheeled vehicle frame structure. Background Technology

[0002] Electric two-wheeled vehicles are two-wheeled vehicles that use batteries as auxiliary power and are equipped with motors and control systems. They include three main categories: electric bicycles, electric mopeds, and electric motorcycles. The function of the frame is to support and connect the various assemblies of the vehicle, keep the assemblies in a relatively correct position, and withstand various internal and external loads. Therefore, the frame must have sufficient strength and rigidity to withstand the load of the vehicle and the impact transmitted from the wheels.

[0003] Currently, common electric vehicle frames on the market cannot effectively balance structural strength and lightweight design. During riding, due to unreasonable structure, problems such as shaking and insufficient strength are prone to occur. At the same time, the bottom box of the frame is used to house the battery, and its bottom is mostly directly fitted with a plastic shell, which has low safety and a high risk of fire. In addition, the large electric two-wheelers on the market today are heavy and bulky, and during normal riding, their sides are prone to scraping against road obstacles or other vehicles and tipping over. Their corresponding outer shells have low strength and are prone to wear and crushing. Utility Model Content

[0004] The purpose of this utility model is to provide a two-wheeled vehicle frame structure that can enhance the overall resistance to deformation while ensuring lightweight design, making riding more stable, improving the fire safety of the power supply placement, and finally buffering the side scraping problem and assisting in supporting the vehicle body shell in the event of a rollover to prevent it from being crushed by its own weight.

[0005] To achieve the above objectives, a two-wheeled vehicle frame structure is provided, comprising: a main beam tube; main side tubes are symmetrically welded and fixed to the lower outer side of the main beam tube; the right end of the opposite side of the main side tube is correspondingly welded and fixed; a horizontal tube is welded and fixed to the bottom end of the main beam tube; the front and rear ends of the horizontal tube are correspondingly welded and fixed to the main side tube; upper side tubes are welded and fixed to the upper middle part of the main side tube, and the upper side tubes are all mounted above the horizontal tubes; a hollow pad is welded and fixed to the middle of the bottom side of the main side tube; horizontal insertion tubes are symmetrically mounted on the left and right sides of the hollow pad; the front and rear ends of the horizontal insertion tubes extend into the inner wall of the main side tube and are welded and fixed thereto; fireproof pads are fixedly connected between the horizontal insertion tubes and the hollow pad; the upper side of the fireproof pads is directly in contact with the electric vehicle power supply; and the right end of the opposite side of the main side tube is... Cylindrical tubes are symmetrically welded and fixed at their respective positions. Anti-collision ball sleeves are symmetrically welded and fixed at opposite ends of the cylindrical tubes. A horizontal tube is welded to the main side tube, and an upper side tube is welded to the main side tube at a position above the horizontal tube-main side tube welding position. Simultaneously, the horizontal tube is welded to the main beam tube at a position below the upper tube-main side tube welding position. The two are combined and welded to form a cage-like structure, which enhances the overall resistance to deformation and makes riding more stable while ensuring lightweight design. In addition, a hollow pad is added to the bottom of the power supply area to fix the main side tube with the horizontal insertion tube and a fireproof pad is laid to replace the bottom plastic shell, improving its fire safety. Finally, cylindrical tubes and anti-collision ball sleeves are symmetrically welded to both sides of the main side tube and are semi-embedded on the outside of the body shell to buffer the side scraping problem and assist in supporting the body shell during rollover, preventing it from being crushed by its own weight.

[0006] According to the aforementioned two-wheeled vehicle frame structure, the upper tubes are all made of square tubing, and their tops are provided with several hot-melt stretching holes. These hot-melt stretching holes are fitted with nuts to secure the frame components, facilitating stable assembly with the vehicle body components.

[0007] According to the two-wheeled vehicle frame structure described above, wear-resistant linings are fixedly connected to the outer sides of the opposite ends of the anti-collision ball sleeves. This improves their scratch resistance and extends their service life.

[0008] According to the two-wheeled vehicle frame structure described above, the opposite ends of the cylindrical tubes are all inclined to the right, and auxiliary frame rods are welded and fixedly connected to the middle of the opposite side of the anti-collision ball sleeves. The opposite ends of the auxiliary frame rods are welded and fixed to the main side tubes. The inclined installation helps to distribute the force and reduce the stress on the cylindrical tubes.

[0009] According to the aforementioned two-wheeled vehicle frame structure, the horizontal tube is a straight tube, but not limited to a straight tube; it can also be bent downwards or backwards and then welded and fixed to the main side tube. This allows for adaptability changes to accommodate different vehicle front designs.

[0010] According to the two-wheeled frame structure described above, the upper tube is a straight tube, but not limited to a straight tube; it can also be bent upwards and welded to the main tube. Side panels of varying heights are provided depending on the size of the vehicle body shell.

[0011] The above-mentioned solution has the following beneficial effects:

[0012] In this invention, a cage-like structure is formed by welding a horizontal tube to the main side tube and a top tube to the main side tube, with the welding position above the welding position of the horizontal tube and the main side tube. Simultaneously, the horizontal tube is welded to the main beam tube, with the welding position below the welding position of the top tube and the main side tube. The two are combined and welded together to form a cage structure, which enhances the overall resistance to deformation while ensuring lightweighting and making riding more stable. In addition, a hollow pad is added at the bottom of the power supply area to fix the main side tube with the horizontal insertion tube and a fireproof pad is laid to replace the bottom plastic shell, improving its fire safety. Finally, cylindrical tubes and anti-collision ball sleeves are symmetrically welded on both sides of the main side tube and are correspondingly semi-embedded on the outside of the body shell to buffer the side scraping problem and assist in supporting the body shell during rollover, preventing it from being crushed by its own weight.
