Description

Technical Field

[0001] The present invention relates to the field of electric bicycles, in particular to an integrated aluminum alloy frame for electric bicycles. Background Art

[0002] An electric bicycle is a mechatronic personal transportation vehicle that uses a battery as an auxiliary energy source and is based on an ordinary bicycle and is equipped with a motor, controller, battery, handlebars and other operating components and a display instrument system. Compared with a bicycle, it has the following characteristics: it is mainly powered by electricity and supplemented by human riding. The battery is installed on the frame, and a motor is added to the rear wheel. The rear wheel diameter is reduced, the tire is relatively wide, and the riding speed does not exceed 26 kilometers per hour. Since electric straight-line bicycles have more components to control the electric drive than classic bicycles, the structure of the bicycle frame has some characteristics of a motorcycle. The frame is relatively heavy and has a relatively low center of gravity, losing the original lines and lightness of the bicycle. Therefore, following market trends, the electric bicycle frame has been transformed from the original assembled frame to an aluminum alloy integrated frame for lightweighting. However, the existing electric bicycle integrated frame cannot guarantee its support while ensuring the lightweight effect, and the protection effect on the battery is insufficient. Therefore, there is a need for an electric bicycle aluminum alloy integrated frame.

[0003] The existing electric bicycle aluminum alloy integrated frame cannot effectively ensure the lightweight effect of the frame body while improving the overall support effect during operation, and cannot improve the stability of the battery during use of the device. Therefore, an electric bicycle aluminum alloy integrated frame is urgently needed. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide an electric bicycle aluminum alloy integrated frame to solve the problem that the existing electric bicycle aluminum alloy integrated frame cannot effectively ensure the lightweight effect of the frame body while improving the overall support effect when in use, and cannot improve the stability of the battery during the use of the device.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an integrated aluminum alloy frame for an electric bicycle, comprising a frame body, a rear seat frame at the rear end of the frame body, a wheel bearing frame installed at the lower end of the rear seat frame, a right-angle supporting rod installed at the lower end of the rear seat frame, a main shaft hole provided at the front end of the frame body, a battery slot provided at the inner end of the frame body, a supporting pad installed inside the battery slot, a cover installed at the upper end of the battery slot, a top pad installed at the lower end of the cover, an air inlet provided at the middle end of the frame body, an intake fan installed at the inner end of the air inlet, an air outlet provided at the rear end of the frame body, an integrally formed arrangement of the frame body, and the wheel bearing frame symmetrically arranged with the central axis of the rear seat frame.

[0006] Preferably, the right-angle support rod and the rear seat frame are arranged at a forty-five-degree angle, and the right-angle support rod and the frame body are integrally formed.

[0007] Preferably, the support pad is movably connected to the frame body through the battery slot, and the outer end surface of the support pad is tightly fitted with the inner end surface of the battery slot.

[0008] Preferably, the upper end surface of the top pad is tightly fitted with the lower end surface of the cover, and the cover is threadedly connected to the frame body.

[0009] Preferably, the air inlet fan is snap-connected to the air inlet, and the opening direction of the air inlet is arranged horizontally to the ground.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The present invention places the battery in the battery slot by arranging a frame body, a battery slot, a supporting pad, a top pad, a cover, an air inlet, an air intake fan, and an air outlet. The supporting pad and the top pad are used to isolate the battery from direct contact with the inner wall of the frame body, and the cover is used to seal the battery slot, effectively preventing damage to the battery caused by vibration generated during long-term use of the device. At the same time, during driving, the frame body constantly supplies air into the battery slot through the air inlet and the air intake fan, and quickly dissipates heat through the air outlet, thereby achieving stable heat dissipation and improving the stability of the battery during use of the device.

[0012] 2. The present invention provides a frame body, a rear seat frame, a wheel support frame, a right-angle support rod, a battery slot, an air inlet and an air outlet, and integrally forms the frame body with the rear seat frame, the wheel support frame, the right-angle support rod, the battery slot, the air inlet and the air outlet with an aluminum alloy material for reverse molding production. The wheel support frame and the right-angle support rod can be used to enhance the support of the recoil force, thereby ensuring the lightweight effect of the frame body and improving the overall support effect.
