NEW BICYCLE FRAME TUBE
Document Type and Number:
WIPO Patent Application WO/2019/071860
Kind Code:
A1
Abstract:
A new bicycle frame tube. The tube body (1) has a cross section of a mono-cavity with a closed U-shaped structure, and is composed of a bottom portion, two side walls and a top portion in a closed manner, the two side walls being provided parallel to each other, and the side walls being connected to the top portion by means of corner parts; the middle section of the tube body is provided, by removing the top portion and the connected corner parts, with an open slot (2) for placing a battery cassette, the cross section of the open slot maintaining the two side walls and the bottom portion; and in the cavity of the tube body, at least one protruding cross brace (3) is provided in the lower portion of the open slot, two ends of the cross brace being fixedly connected to the sidewalls in a vertical direction. The sidewalls of the tube body have a wrapping structure with a thick top and thin bottom, and in cases of falling or side collision of a lithium electric bicycle during riding, the battery is subjected to a force which leaves it severely deformed, causing a secondary accident of battery explosion; however, the wrapping sidewalls protect the battery case, reducing the probability of the accident occurring. Meanwhile, the bottom of the tube body has a V-shaped structure or an arc-shaped structure, providing strong impact resistance capability and strong bending resistance.
