Referring to fig. 1 to 3, a rear anti-collision plastic guard plate of an electric bicycle comprises an anti-collision plastic guard plate body 1 connected to a frame, wherein the anti-collision plastic guard plate body 1 covers the upper part of a tire 2. The crashproof plastic fender body 1 is located between the tire 2 and the power battery in the vehicle body, primarily for the purpose of avoiding damage to the tire 2 during impact, and secondarily for providing cushioning protection between the battery and the tire 2.

The crashworthy plastic fender body 1 includes a front crashworthy panel 11, a middle crashworthy panel 12, and a rear crashworthy panel 13. The front anti-collision plate 11, the middle anti-collision plate 12 and the rear anti-collision plate 13 are of arc structures, the front anti-collision plate 11 is coated on the front side of the tire 2, the middle anti-collision plate 12 is coated on the middle of the tire 2, and the rear anti-collision plate 13 is coated on the rear side of the tire 2. The front anti-collision plate 11 and the middle anti-collision plate 12 are detachably connected through a metal rubber support 14. The middle anti-collision plate 12 and the rear anti-collision plate 13 are integrally connected and formed, and the front anti-collision plate 11, the middle anti-collision plate 12 and the rear anti-collision plate 13 are all made of flexible plastics. The middle impact plate 12 and the rear impact plate 13 are selected to be integrally formed. The front anti-collision plate 11 is elastically connected with the middle anti-collision plate 12 through a metal rubber support 14, and the metal rubber support 14 is selected from the existing conventional metal rubber components. The middle anti-collision plate receives forward impact due to the metal rubber support 14, so that the metal rubber support 14 is deformed, and the front anti-collision plate 11, the middle anti-collision plate 12 and the rear anti-collision plate 13 form a package for the tire 2. The flexible plastic enables the anti-collision plastic guard plate body 1 to have good impact resistance effect, so that the anti-collision plastic guard plate body 1 is prevented from being damaged by collision, and the anti-collision plastic guard plate has long service life.

The inner wall of the front impact plate 11 is provided with a rubber lining 111. The front end of the front impact plate 11 has a cushion block 112, and the cushion block 112 is a foam cushion block 112. The buffer block 112 is proximate to the area of the frame where the battery pack is mounted. When the front fender 11 contacts the tire 2, the rubber lining 111 contacts the tire 2, thereby further cushioning the tire. The front buffer block 112 is to prevent the collision from being excessively stressed, and further buffer between the front crash panel 11 and the vehicle body, so as to prevent the battery inside the vehicle body from being impacted.

The two sides of the middle anti-collision plate 12 are provided with connecting brackets 121, and the connecting brackets 121 are movably connected to the frame. The rear anti-collision plate 13 is forced to push the middle anti-collision plate 12 to drive the connecting bracket 121 to rotate anticlockwise relative to the frame. In the case that the middle crash panel 12 is only impacted greatly, the connecting bracket 121 rotates at a small angle relative to the frame (generally the position of the transmission part of the tire 2), disperses the impact force, and has a protective effect on the tire 2.

The inner wall of the rear anti-collision plate 13 is provided with an anti-collision beam 131 which is transversely connected, the anti-collision beam 131 is positioned right behind the tire 2, and the anti-collision beam 131 is a plastic anti-collision beam. The rear fender 13 has outwardly extending side wings 132 on the left and right sides, and the side wings 132 are wrapped around the outside of the tire 2. The anti-collision beam 131 is mainly used for providing buffering for the rear anti-collision plate 13 and the tire 2, so that the tire 2 is prevented from being directly impacted, and the tire 2 is effectively prevented from being damaged due to impact.

The rear side of the anti-collision plastic guard plate body 1 is impacted to enable the front anti-collision plate 11, the middle anti-collision plate 12 and the rear anti-collision plate 13 to relatively shrink so as to wrap and buffer the inner tire 2. The rear anti-collision plate 13 is impacted forwards, the rear anti-collision plate 13 is bent and deformed, the anti-collision beam 131 inside the rear anti-collision plate 13 is close to the tire 2 and is attached to the tire 2, the impact force received by the tire 2 is dispersed, and the tire 2 and the transmission part are prevented from being damaged due to impact received by the tire 2. Meanwhile, the collision can be transferred to the front anti-collision plate 11 through the middle anti-collision plate 12, the front anti-collision plate 11 and the middle anti-collision plate 12 can contract relatively due to the action of the metal rubber support 14, the front anti-collision plate 11, the middle anti-collision plate 12 and the rear anti-collision plate 13 play a role in protecting the tire 2, and the rubber lining inside the front anti-collision plate 11 is synchronously contacted with the tire 2, so that the impact of the tire 2 on the front anti-collision plate is further lightened. The front buffer block absorbs the impact transferred to the vehicle body, so that the battery in the vehicle body is prevented from being impacted, and the battery can be protected.

Compared with the prior art, the rear anti-collision plastic guard plate of the electric bicycle can play a good buffering protection role when the rear part of the electric bicycle is impacted, and buffer is carried out between the tire and the battery in the bicycle body, so that the safety of the tire and the battery is synchronously protected.

The utility model and its embodiments have been described above by way of illustration and not limitation, and the utility model is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present utility model.
