Background technique

Thanks to its lightweight size, the scooter is easy to carry and makes it a popular sports and leisure tool. When the scooter encounters uneven road surface during use, the pedal of the scooter will be unstable with the upper and lower jumps of the front and rear wheels, and the user's foot can be caused by the excessive bounce of the rear wheel. Slide down on the pedal. Therefore, some scooters have attempted to provide a shock absorber between the pedal and the rear wheel to avoid excessive bounce of the rear wheel, thereby enhancing the handling performance of the scooter and reducing the speed of wear of the rear wheel. The Chinese patent No. 01200536. 6 discloses a folding scooter having a suspension structure, mainly a shock absorber end pivoted by a lower end of a connecting piece of a scooter handle frame, and the other end of the eliminator The utility model is pivotally fixed in the concave seat of the long body of the vehicle body, so that a shock absorber is connected between the scooter body and the handle frame, so that the scooter has a shock absorbing buffer device, and the sliding through various flat, four convex and rugged In the process of performing various fancy fancy movements on uneven ground, it forms a protective effect on the body of the "performer" to prevent the safety effect of injury and injury. However, such a suspension structure still has many shortcomings and needs further improvement.

Utility model content

However, the structure of the general scooter suspension device is quite complicated, and when driving on a road surface having a large height and a low drop, the pedal may be excessively bounced due to the excessive compression stroke of the spring, even when the pedal is depressed, The pedal touches the ground and is dangerous.

In view of this, in order to provide a rear suspension structure that is different from the conventional scooter, the above shortcomings are improved, and the following objectives are achieved, and the applicant has accumulated many years of experience and continuous research and development improvements. Health.

The purpose of the utility model is to provide a rear shock absorber structure of a scooter which has a simple structure and can effectively reduce the production cost.

The utility model aims to provide a rear shock absorber structure of a scooter which can not only achieve the shock absorber suspension effect, but also allows the user to ride comfortably, can reduce the wear speed of the rear wheel, and can effectively ensure the safety of use.

In order to achieve the above utility model, the rear suspension structure of the scooter provided by the utility model is connected between the rear end of the pedal and the rear wheel, and the rear suspension structure comprises a bracket and an elastic member. The bracket is disposed under the rear end of the pedal, the bracket extends forwardly to a front pivoting portion, the front pivoting portion is pivotally connected to the pedal, and the left and right sides of the bracket respectively extend rearwardly to a rear positioning piece, two rear The positioning piece is coaxially fixed to the left and right sides of the rear wheel; and the elastic member is positioned between the rear end of the pedal and the bracket for the user to step on the pedal, and the rear wheel contacts the ground to achieve the shock absorber effect. .

In the implementation, the front pivoting portion includes a front pivoting piece extending forwardly from the left and right sides of the bracket, and the two front pivoting pieces are coaxially pivoted to the left and right sides of the pedal.

In practice, the bottom end of the bracket is provided with a bottom plate having a through hole, and a screw is passed up through the through hole and the elastic member, and the elastic member is positioned between the rear end of the pedal and the bracket.

In implementation, the bottom surface of the rear end of the pedal is provided with a limiting portion for limiting the elastic member, and the elastic member is a spring. The utility model has the following advantages:

1. The utility model has the advantages of simple structure and easy assembly, and therefore not only can effectively reduce the production cost, but also has high practicability.

2. The utility model can effectively limit the elastic member between the lower part of the pedal and the bracket, and let the shaft move up and down in the notch below the rear end of the pedal. Therefore, not only can the buffer shock effect be effectively generated, so that the use The ride is comfortable, and the speed of the rear wheel wear is reduced, and the road can be prevented from being too large or the pressure path under the pedal is too large, causing the pedal to touch the road surface due to excessive drop to improve the stability of the control. Sex, make sure it is safe to use.

In summary, according to the above disclosure, the utility model can achieve the intended purpose, and provides a speed that not only can achieve the shock absorber and reduce the wear of the rear wheel, but also can increase the stability of the operation to ensure the use. The safety of the rear shock absorber structure of the scooter is of great industrial value.

In order to facilitate a more in-depth understanding of the present invention, it will be described in detail later.

The technical solutions of the present invention will be further described below with reference to the accompanying drawings and preferred embodiments. The rear suspension structure of the scooter of the utility model is connected between the rear end of the pedal and the rear wheel, and the rear suspension structure comprises a bracket and an elastic member. The front pivoting portion extending forwardly of the bracket is pivotally connected to the pedal, and the rear positioning piece extending backward from the left and right sides of the bracket is coaxially fixed to the left and right sides of the rear wheel; and the elastic member is positioned on the pedal Between the back end and the bracket.

As shown in FIG. 1 and FIG. 2, which is a preferred embodiment of the rear suspension structure 1 of the scooter of the present invention, the rear suspension structure 1 includes a bracket 2 and an elastic member 3.
