Description

jumping bike

本实用新型涉及一种蹦跳自行车，尤其是一种娱乐、健身用自行车。The utility model relates to a jumping bicycle, in particular to a bicycle for entertainment and fitness.

现有自行车前后轮均为圆形，车架通过前后轮圆心上的轴与前后轮相连，行进时车架平衡，车手骑行时，平稳无颠簸，没有刺激感。The front and rear wheels of the existing bicycle are all circular, and the vehicle frame is connected with the front and rear wheels through the shaft on the center of the front and rear wheels.

本实用新型目的在于提供一种行进时，车架上下颠簸，有蹦跳自行车感觉的娱乐、健身用自行车。The purpose of the utility model is to provide a bicycle for entertainment and body-building that has the feeling of a bouncing bicycle when the vehicle frame bumps up and down when traveling.

本实用新型另一目的在于提供通过链传动的蹦跳自行车Another purpose of the utility model is to provide a jumping bicycle driven by a chain

本实用新型目地是这样实现的。The utility model purpose is achieved in this way.

蹦跳车，由前后车轮、车架、车把组成，后车轮的圆心上装有偏心轮盘，在偏心轮盘另有一偏心轴，车架末端有车架轴，车架通过车架轴铰接的摆臂与偏心轴活动连接，在车架末端还固设有滑套，滑杆一端活动穿设滑套内，另一端通过滑杆轴铰接在摆臂上，滑杆外圈套设有弹簧。The jumping car is composed of front and rear wheels, a frame and a handlebar. The center of the rear wheel is equipped with an eccentric wheel, and there is another eccentric shaft on the eccentric wheel. The end of the frame has a frame shaft. The arm is movably connected with the eccentric shaft, and a sliding sleeve is fixed at the end of the vehicle frame. One end of the sliding rod is movable through the sliding sleeve, and the other end is hinged on the swing arm through the sliding rod shaft. The outer ring of the sliding rod is covered with a spring.

本实用新型另一目的是通过设有小链轮，小链轮通过链条与大链轮相连，大链轮上固定有齿轮，车架上还设有踏板，踏板与车架之间设有弹簧，踏板一端固定有齿条，齿条与齿轮相啮合来实现的。Another purpose of the utility model is to provide a small sprocket, the small sprocket is connected with the large sprocket through a chain, the large sprocket is fixed with a gear, the frame is also provided with a pedal, and a spring is arranged between the pedal and the frame. , One end of the pedal is fixed with a rack, and the rack and the gear are meshed to achieve.

由于采用了偏心轴的结构，后车轮运动时，偏心轴将绕后车轮轴转动，从而使与偏心轴相连的车架上下起伏，产生强烈的颠簸，车手有明显的蹦跳感。Due to the structure of the eccentric shaft, when the rear wheel moves, the eccentric shaft will rotate around the rear wheel axis, so that the frame connected to the eccentric shaft will rise and fall up and down, resulting in strong bumps, and the driver will have an obvious sense of jumping.

图2为本实用新型一实施例动力蹦跳自行车的俯视图。Fig. 2 is a top view of a powered jumping bicycle according to an embodiment of the present invention.

图3为本实用新型另一实施例带有链轮的有动力蹦跳自行车的正视图。Fig. 3 is a front view of a powered jumping bicycle with a sprocket according to another embodiment of the utility model.

由图1、图2可见，动力蹦跳自行车由由前后车轮、车架、车把组成，后车轮7的圆心上装有偏心轮盘6，在偏心轮盘6另有一偏心轴10，车架1末端有车架轴12，车架1通过车架轴12铰接的摆臂8与偏心轴10活动连接，在车架1末端还固设有滑套3，滑杆2一端活动穿设滑套3内，另一端通过滑杆轴11铰接在摆臂上，滑杆2外圈套设有弹簧4As can be seen from Fig. 1 and Fig. 2, the power jumping bicycle is made up of front and rear wheels, a vehicle frame and a handlebar. The center of the circle of the rear wheel 7 is equipped with an eccentric wheel 6, and an eccentric shaft 10 is arranged on the eccentric wheel 6, and the end of the vehicle frame 1 There is a frame shaft 12, the frame 1 is movably connected with the eccentric shaft 10 through the swing arm 8 hinged by the frame shaft 12, and a sliding sleeve 3 is fixed at the end of the frame 1, and one end of the sliding rod 2 is movably inserted into the sliding sleeve 3 , the other end is hinged on the swing arm through the slider shaft 11, and the outer ring of the slider 2 is provided with a spring 4

由图3可见，车架上连接有一个车座21，车座上设有转轴20，车座可绕转轴在垂直平面内大角度转动。在骑行时，将车座放置在座面水平，车手可坐在车座位上，站立行进时，将车座在垂直面内旋转90度，车手腰部可靠在车座翻起的面上，使行车更安全，舒适。As can be seen from Fig. 3, a vehicle seat 21 is connected to the vehicle frame, and the vehicle seat is provided with a rotating shaft 20, and the vehicle seat can rotate at a large angle in a vertical plane around the rotating shaft. When riding, place the seat at the level of the seat surface, and the driver can sit on the seat. When standing and running, turn the seat 90 degrees in the vertical plane, and the rider's waist can rest on the raised surface of the seat, so that the driver can ride on the seat.
