Description

Technical Field

[0001] The utility model relates to the technical field of scooters, in particular to a frame of an electric scooter. Background Art

[0002] A scooter is an electric vehicle, and its main structure includes a frame, wheels and a battery box. A wheel is installed at each of the front end and the rear end of the frame. A motor is coaxially installed on the wheel located at the rear end, and the motor is powered by the battery box.

[0003] Generally speaking, the overall structure of the scooter is relatively small. The battery box of the scooter is installed at a position relatively close to the ground on the main beam, with a low ground clearance. Relatively speaking, the buffer space left for the scooter is small. When driving on a bumpy road section, the scooter will be relatively bumpy, and the shock absorption effect is poor. Moreover, since the footrest is arranged above the battery box, when stepping on the footrest, the two feet need to be placed staggeredly, and the comfort is poor. There is basically no space to place other things after stepping on the footrest, and the space of the scooter is small.

[0004] Therefore, we propose a frame of an electric scooter to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a frame of an electric scooter to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A frame of an electric scooter includes two support beams. A head tube is fixedly welded to the left ends of the two support beams. A base is arranged on the right side of the support beams, and the two support beams are fixedly welded to the base. Pedals are installed on both the left and right sides of the base. A support tube is arranged below the two support beams. The left end of the support tube is fixedly connected between the two support beams, and the right end of the support tube is fixedly welded to the base. A seat board is arranged above the base, and the seat board is fixedly connected between the two support beams. Two rear fork tubes are arranged on the right side of the base, and the two rear fork tubes are rotatably connected to the base. The seat board and the rear fork tubes are fixedly connected through a shock absorption mechanism.

[0008] Further, the base includes two baffle plates. A main support rod and an auxiliary support rod are fixedly welded between the two baffle plates. A return plate is fixedly connected between the main support rod and the auxiliary support rod. A rotating shaft is arranged on the right side of the main support rod, and the rotating shaft is rotatably connected to both of the two baffle plates.

[0009] Further, the shock-absorbing mechanism includes two telescopic rods. The upper ends of the two telescopic rods are rotatably connected to the lower end of the seat plate. The lower ends of the two telescopic rods are rotatably connected to the same fixed pipe. The two ends of the fixed pipe are fixedly welded to the two rear fork pipes respectively. An adjusting ring and a buffer spring are sleeved outside the telescopic rod. The adjusting ring is threadedly connected to the outer side wall of the telescopic rod. An abutting ring is provided at the lower end of the telescopic rod. The two ends of the buffer spring are fixedly connected to the adjusting ring and the abutting ring respectively.

[0010] Further, the pedal is integrally trapezoid-shaped. A plurality of through holes are provided through the left and right of the pedal. A fixing plate is rotatably connected to one side of the pedal close to the base. The fixing plate is fixedly connected to the baffle.

[0011] Further, the two support beams are fixedly welded to the main support rod. The support pipe is fixedly welded to the auxiliary support rod. The two rear fork pipes are fixedly welded to the rotating shaft respectively.

[0012] Further, a vertical rod is fixedly welded between the main support rod and the seat plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are at least as follows:

[0014] 1. By providing the pedal and the seat plate, when riding the scooter, one can sit on the seat plate, and then place the feet apart on the two pedals respectively. The riding comfort is better. Moreover, when not riding, the pedals can be retracted, occupying less space. And the space between the seat plate and the support beam is relatively wide, where other things can be placed;

[0015] 2. By providing the support pipe, the space between the support pipe and the two support beams is relatively wide, where the battery box and other parts can be installed, removing the installation space at the base, increasing the overall height of the scooter from the ground, improving the passability of the scooter and leaving a relatively large buffer space;

[0016] 3. By providing the shock-absorbing mechanism, when passing through bumpy roads, on the one hand, the height of the base from the ground is relatively high, and the passability is good. On the other hand, under the buffering action of the buffer spring and the telescopic rod, the bumps caused by the uneven road surface are greatly reduced, and the riding is relatively stable, improving the riding comfort.

[0017] The present utility model has good passability, stable riding, wide placement space, good buffering effect, and improves the riding comfort. BRIEF DESCRIPTION OF THE DRAWINGS
