Description
Technical Field
The utility model relates to an electric bicycle subassembly especially relates to an electric bicycle's frame.
Background
When the electric bicycle runs on a paved road surface, the road surface is relatively flat, so that a damping device is not required to be specially arranged, and comfortable riding can be realized by the buffer action of the tyre. But when the road surface is uneven, the driver feels strong jolt, and the riding comfort is reduced. In order to realize the comfort of the electric bicycle when riding on uneven road surfaces, the electric bicycle needs to be subjected to damping design. Through research, the frame with the good damping effect is provided.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem that exists among the background art, the utility model provides an electric bicycle's shock attenuation frame, this shock attenuation frame has the shock attenuation effect of preferred for have comfortable sitting when riding and feel.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an electric bicycle shock attenuation frame, includes the seat tubular beam, and the bottom of seat tubular beam has the centre bore, stretches out two fork arms down to electric bicycle's rear side from the centre bore, and the end of two fork arms in keeping away from the centre bore keeps certain distance apart its characterized in that down: the middle part position of seat tubular beams is provided with the go-between of two parallels, is provided with the axis of rotation on the go-between in the part that lies in the outside, is provided with the torsional spring between axis of rotation and the go-between, and the end at axis of rotation both ends is fixed with respectively rotates the short arm, and the other one end that rotates the short arm articulates respectively has last wishbone, goes up the wishbone slope and sets up, goes up the wishbone and keeps away from the one end that rotates the short arm and link to each.
The upper part of the seat tube beam is provided with a seat cushion of the electric bicycle.
The centre shaft hole is used for setting the centre shaft of the electric bicycle.
Both connecting rings are fixed on the seat tube beam.
The two ends of the rotating shaft extend out of the connecting ring.
One end of the upper fork rod, which is far away from the short rotating arm, is fixedly connected with the lower fork rod through a rear axle clamp.
The rear axle clamp is used for arranging a rear axle of the electric bicycle.
The utility model has the advantages that: shock attenuation frame can pass through the torsional spring absorption that sets up between axis of rotation and the go-between with the vibration of rear wheel to make this frame have good shock attenuation effect, have good sitting and feel when riding rugged road.
Drawings
The present invention will be further explained with reference to the accompanying drawings
Fig. 1 is a schematic structural view of a shock-absorbing frame of the present invention;
Detailed Description
The invention will be further described with reference to the following description and embodiments in conjunction with the accompanying drawings:
example 1
As shown in fig. 1, the shock-absorbing frame of the electric bicycle comprises a seat tube beam 10, and a seat cushion of the electric bicycle is arranged on the upper part of the seat tube beam 10. The bottom of the seat tube beam 10 is provided with a middle shaft hole 21, and the middle shaft hole 21 is used for arranging a middle shaft of the electric bicycle.
Two lower fork rods 20 extend from the center axle hole 21 to the rear side of the electric bicycle, and the two lower fork rods 20 are spaced apart at ends far from the center axle hole 21.
The middle position of seat tubular beam 10 is provided with two parallel go-between 11, and two go-between 11 are all fixed on seat tubular beam 10, are provided with axis of rotation 12 on the part that lies in the outside on go-between 11, are provided with the torsional spring between axis of rotation 12 and the go-between 11, and the both ends of axis of rotation 12 outwards stretch out go-between 11.
The rotating short arms 30 are respectively fixed at the ends of the rotating shaft 12 extending out of the connecting ring 11, the other ends of the rotating short arms 30 are respectively hinged with an upper fork rod 40, the upper fork rod 40 is obliquely arranged, and one end of the upper fork rod 40 far away from the rotating short arms 30 is fixedly connected with the lower fork rod 20 through a rear shaft clamp 41. The rear axle clamp 41 is used for arranging a rear axle of the electric bicycle, and a rear wheel of the electric bicycle is arranged on the rear axle.
This electric bicycle's frame has better shock attenuation effect, and when meetting uneven road, electric bicycle's rear wheel takes place to vibrate, through last fork arm 40, the transmission of rotating short arm 30 and pivot axle 12, the momentum of vibration is absorbed by the torsional spring that sets up between axis of rotation 12 and the go-between 11 to make the cushion on seat tubular beams 10 upper portion not take place obvious vibration, thereby make this electric bicycle still have comfortable sitting and feel on uneven road.
Those skilled in the art will recognize that a wide variety of modifications, alterations, and combinations can be made with respect to the above described embodiments without departing from the scope of the invention, and that such modifications, alterations, and combinations are to be viewed as being within the ambit of the inventive concept.
