Problems solved by technology
[0002]The existing electric bicycles are all positive front forks, and the length of the shock absorber rod of the forward fork is greater than the length of the sleeve, so the weight of the shock absorber rod is smaller than that of the sleeve The extra weight is added to the electric vehicle as a whole, which will make the overall quality of the electric vehicle heavier. It is often said that "one catty lighter on the wheel is ten catties lighter on the car", and conversely "the wheel The top weighs one catty, and the car weighs ten catties", which will cause a bad riding experience for the bicycle during driving.

The invention provides an inverted front fork for an electric bicycle, which comprises a vertical pipe, an insertion shoulder assembly, a first shock-proof rod, a second shock-proof rod, a first front axle fixing piece and a second front axle fixing piece, and is characterized in that the insertion shoulder assembly comprises an insertion shoulder body, a first sleeve and a second sleeve, the first sleeve is fixedly connected to one end of the insertion shoulder body, and the second sleeve is fixedly connected to the other end of the insertion shoulder body; the second sleeve is fixedly connected to the other end of the insertion shoulder body, so that the insertion shoulder assembly forms a U-shaped integrated structure, the vertical pipe is fixedly installed in the middle of the insertion piece body, and a connecting structure of the vertical pipe and the insertion shoulder assembly forms an inverted Y shape. The first end of the first shock-proof rod is connected to the first sleeve in a sleeving mode through a spring, the first end of the second shock-proof rod is connected to the second sleeve in a sleeving mode through a spring, the first front shaft fixing piece is fixedly connected to the second end of the first shock-proof rod, and the second front shaft fixing piece is fixedly connected to the second end of the second shock-proof rod. The inverted front fork is used, the on-wheel mass of the electric bicycle is reduced, a rider feels more portable in the riding process, and the shock absorption effect is improved.
Description
technical field [0001] The invention belongs to the field of electric bicycles, in particular to an inverted front fork for electric bicycles. Background technique [0002] The existing electric bicycles are all forward forks. The length of the shock absorber of the forward fork is greater than the length of the sleeve, so the weight of the shock absorber is larger than that of the sleeve, and the extra weight is added to the whole electric vehicle. It will make the overall quality of the electric vehicle heavier. It is often said that "one pound is lighter on the wheel, ten pounds lighter on the car", and conversely, "one pound on the wheel is heavier on the wheel, ten pounds on the car". It will cause a bad riding experience to the bike. Therefore, reducing the mass of the electric vehicle and making the rider feel lighter during the riding process is an urgent problem to be solved. SUMMARY OF THE INVENTION [0003] In view of this, the present invention aims to propos...
