AI Technical Summary
When the existing electric bicycle seatposts carry people with a weight of more than 80KG, the quick release clamp cannot effectively lock the seatpost, resulting in the problem of the seatpost sliding.
An electric bicycle seatpost anti-slip system is designed, including a middle pipe, bushing, seatpost and quick-removing clamp, and an anti-slip plug and a convex column are added. The inner convex column of the anti-slip plug is inserted into the socket of the seatpost, and the inner wall of the bushing The convex strips contact the bottom of the anti-slip plug, increasing the stability of the seatpost.
Through the cooperation of the anti-slip plug with the seat post and bushing, the stability of the seat post is significantly improved, preventing the seat post from sliding, and especially preventing the seat post from sliding more effectively under heavy load conditions.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric bicycles, in particular to an anti-skid system for a seat post of an electric bicycle. Background Art
[0002] The seat post of an electric bicycle is used to connect the seat cushion, and the seat post is used to connect the middle tube of the bicycle. A bushing will be inserted into the upper end of the middle tube, and the seat post will extend up and down through the bushing and extend into the middle tube. There is a notch on the upper end of the middle tube, and there is also a notch on the side wall of the bushing. A quick release clamp is installed on the outer sleeve of the middle tube. When the quick release clamp is clamped, the middle tube and the bushing can be clamped and deformed, so that the seat post is clamped. However, the clamping force of the quick release clamp is limited. When the seat post carries a person with a weight of more than 80KG, the downward pressure of the seat post increases due to the overload, and the quick release clamp cannot effectively lock the seat post, causing the seat post to slide down. Therefore, how to develop an anti-skid system for the seat post of an electric bicycle to more effectively prevent the seat post from sliding down is the research direction that the staff in this field want to study. Utility Model Content
[0003] In view of the above-mentioned defects of the prior art, the purpose of the utility model is to provide an anti-skid system for the seat post of an electric bicycle.
[0004] The technical solution of the utility model is: an anti-skid system for the seat post of an electric bicycle, which includes a middle tube, a bushing, a seat post and a quick-release clamp, the bushing is plugged into the upper end of the middle tube, the seat post extends up and down through the bushing and then extends into the middle tube, the quick-release clamp is clamped outside the upper end of the middle tube, and it also includes an anti-skid plug, the outer wall of the seat post is provided with a plurality of vertically distributed insertion holes, the inner side of the anti-skid plug is convexly provided with a convex column, the convex column is inserted into the insertion hole, a convex strip is convexly provided on the inner wall of the bushing, and the bottom of the anti-skid plug rests on the top of the convex strip.
[0005] Furthermore, the upper end of the bushing is provided with an outwardly protruding convex ring, and the convex ring is pressed on the top of the middle tube.
[0006] Furthermore, a sliding groove extending up and down is provided on the outer wall of the seat post, and the convex strip is inserted into the sliding groove.
[0007] Furthermore, the number of the bosses is two, and the two bosses are inserted into two of the insertion holes.
[0008] The application of the electric bicycle seat post anti-skid system provided by the utility model has the beneficial effect that after the anti-skid plug is used together with the seat post and the bushing, an additional function of preventing the seat post from sliding down is added, and the effect of preventing sliding down is better.

[0016] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model:
[0017] like Figure 1 — Figure 6 As shown, the anti-skid system of the seat post of an electric bicycle includes a middle tube 1, a bushing 2, a seat post 3 and a quick-release clamp 4. The bushing 2 is inserted into the upper end of the middle tube 1, and the seat post 3 extends up and down through the bushing 2 and then extends into the middle tube 1. The quick-release clamp 4 is clamped outside the upper end of the middle tube 1. It also includes an anti-skid plug 5. The outer wall of the seat post 3 is provided with a plurality of vertically distributed insertion holes 31. The inner side of the anti-skid plug 5 is convexly provided with a convex column 51, and the convex column 51 is inserted into the insertion hole 31. A convex strip 21 is convexly provided on the inner wall of the bushing 2, and the bottom of the anti-skid plug 5 rests on the top of the convex strip 21.
[0018] The upper end of the bushing 2 has an outwardly protruding convex ring 22 , and the convex ring 22 is pressed on the top of the middle pipe 1 .
[0019] The outer wall of the seat rod 3 is provided with a sliding groove 32 extending up and down, and the convex strip 21 is inserted into the sliding groove 32. The outer side and the upper and lower ends of the sliding groove 32 are open, and the plug hole 31 is distributed in the middle and upper part of the sliding groove 32, and the sliding groove 32 is also for the anti-skid plug 5 to be inserted, and the plug hole 31 is through inside and outside.
[0020] like Figure 5 As shown, in order to firmly fix the anti-slip plug 5 to the outer wall of the seat post 3 , there are two bosses 51 , and the two bosses 51 are inserted into two of the insertion holes 31 .
[0021] like Figure 4 and Figure 6As shown, a first notch 11 is provided at the upper end of the middle tube 1, and a second notch 23 is provided at the outer side of the bushing 2. The purpose of setting the first notch 11 and the second notch 23 is that when the quick release clamp 4 is clamped on the upper end of the middle tube 1, the middle tube 1 and the bushing 2 can both be deformed, so that the seat post 3 is clamped.
[0022] like Figure 3 As shown, the bottom of the anti-skid plug 5 rests against the top of the convex strip 21, so the convex strip 21 can block the anti-skid plug 5 and prevent the anti-skid plug 5 from sliding down, and then the seat post 3 will not slide down either.
[0023] When the height of the seat post 3 is to be adjusted, the quick release clamp 4 is opened, the anti-slip plug 5 is removed, and the protrusion 51 of the anti-slip plug 5 is inserted into the other insertion holes 31, so that the height can be adjusted. The number of the insertion holes 31 is preferably 11, so there are many height options.
[0024] The electric bicycle seat post anti-skid system provided by the utility model has an anti-skid plug 5 which, when used together with the seat post 3 and the bushing 2, has an additional function of preventing the seat post 3 from sliding down, and the anti-skid effect is better.
[0025] Of course, the above are only preferred embodiments of the present invention, and the patent scope of the present invention is not limited thereto. All simple modifications and equivalent structural changes made using the description and drawings of the present invention should be included in the patent protection scope of the present invention.
