Description

Rocker Drive Scooter

a technical field

The utility model is a scooter used for entertainment, sports and fitness, in particular to a seesaw-driven scooter.

Two background technology

The scooter can not only be used as a means of transportation, but also widely used in entertainment, sports, and fitness activities. Existing scooters, according to the method of use and structural features, mainly contain three categories:

(1) Two-wheel scooter. The user will use one foot to step on the ground from time to time to make the scooter obtain the power to move forward. This scooter is mainly used for entertainment, sports and fitness for children aged 4-12. Using this scooter has a certain effect on training children's balance ability.

(2) Two-wheel electric scooter. The patent that is 02262556.9 as the patent number is a kind of scooter driven by electric power, is powered by accumulator and motor, and weight is heavier, mainly does walking-replacing tool.

(3) Three-wheeled human-driven scooter. The patent that is 02205908.3 as the patent number is a kind of pedal power unit of three-wheeled scooter. This scooter overcomes the shortcomings of the user pedaling the ground. The user stands on the scooter and constantly steps on a pedal to drive the scooter to move through the transmission system. But this three-wheeled scooter is not as good as the two-wheeled scooter to the training of children's balance ability.

Three invention content

The purpose of the utility model is to provide a seesaw driven scooter which is more sporty and does not need to be driven by pedals.

The technical solution to realize the purpose of this utility model: a rocker-driven scooter, including a steering rod, a front wheel, a frame and a rear wheel, a rocker is arranged on the frame, and the rocker is connected with a rocker to swing it back and forth It is converted into a directional rotation and speeds up to drive the transmission connection of the rear wheel to rotate.

The transmission device of the seesaw-driven scooter of the utility model is to set a first overrunning clutch and a second overrunning clutch on the rotating shaft of the seesaw, the first overrunning clutch is connected with the first gear, and the first gear is connected with the second gear meshing, the second overrunning clutch is connected with the sixth gear, and the sixth gear meshes with the fifth gear through the idler gear; the fifth gear, the second gear and the third gear are arranged on the same shaft, and the third gear The gear is located between the fifth gear and the second gear. The third gear meshes with the fourth gear. The fourth gear and the large sprocket are arranged on the same shaft. The large sprocket is connected with the small sprocket through a chain. The small sprocket is connected with the third overrunning clutch arranged on the rear wheel; the rotating shaft of the seesaw, the two axles in the transmission device and the axle of the rear wheel are all arranged on the vehicle frame.

Compared with the prior art, the utility model has the following remarkable advantages: 1. the user does not need to pedal the ground, but only needs to adjust the center of gravity of the body to make the seesaw swing back and forth to obtain the power for the scooter to continuously advance. ②Used as children's entertainment, sports and health products, it is more entertaining and interesting than existing scooters, and it feels like surfing up and down when stepping on a seesaw. The use of the scooter has a better effect on the training of children's balance ability than the existing scooter. ③Appropriately increasing the size of the wheels and the body can make the scooter have a faster driving speed and can be used as a means of transportation. Compared with electric scooters, it is lighter in weight, lower in cost, and more economical.

Five specific implementation methods

Below in conjunction with accompanying drawing, the utility model is described in further detail.

In conjunction with Fig. 1 and Fig. 2, the seesaw-driven scooter of the present utility model comprises steering rod 1, front wheel 2, vehicle frame 3 and rear wheel 14, and a seesaw 4 is set on the vehicle frame 3, and this seesaw 4 and One converts its (rocker 4) reciprocating swing into directional rotation and speeds up and drives the transmission device that rear wheel 14 rotates to connect. The transmission device is provided with a first overrunning clutch 6 and a second overrunning clutch 18 on the rotating shaft of the seesaw 4, the first overrunning clutch 6 is connected with the first gear 5, and the first gear 5 is meshed with the second gear 7, The second overrunning clutch 18 is connected with the sixth gear 17, and the sixth gear 17 meshes with the fifth gear 15 through the idler gear 16; the fifth gear 15, the second gear 7 and the third gear 8 are arranged on the same root On the shaft, the third gear 8 is located between the fifth gear 15 and the second gear 7, the third gear 8 meshes with the fourth gear 9, and the fourth gear 9 and the large sprocket 10 are arranged on the same shaft. This big chain wheel 10 is connected with small chain wheel 12 by chain 11, and this small chain wheel 12 is connected with the 3rd overrunning clutch 13 that is arranged on the rear wheel 14; The axles of the rear wheels 14 are all arranged on the vehicle frame 3 .

The seesaw-driven scooter of the utility model is provided with a seesaw 4 in the middle of the vehicle frame 3, and the user's feet stand on both ends of the seesaw 4 to make the seesaw 4 swing back and forth, and the motion and power are transmitted to the rear through the transmission device. Wheel 14 enables the scooter to obtain forward momentum. The transmission device transmits the movement of the rocker 4 to the rear wheel 14 through two transmission lines, and converts the reciprocating swing of the rocker 4 into the counterclockwise directional rotation of the rear wheel 14 during the transmission process, driving the vehicle body to move forward. The two transmission lines are:

The first transmission line: when the rocker 4 swings counterclockwise, the motion and power pass through the first overrunning clutch 6, the first gear 5, the second gear 7, the third gear 8, the fourth gear 9, the large sprocket 10, Small sprocket wheel 12, the 3rd overrunning clutch 13 pass to rear wheel 14.

The second transmission line: when the seesaw 4 swings clockwise, the movement and power pass through the second overrunning clutch 18, the sixth gear 17, the idler gear 16, the fifth gear 15, the third gear 8, the fourth gear 9, the large Sprocket 10, small sprocket 12, the 3rd overrunning clutch 13 pass to rear wheel 14.

The transmission device adopts a speed-up transmission, so that even if the user steps on the seesaw 4 slowly, the car body can be kept at a certain speed to maintain balance. The third overrunning clutch 13 realizes the one-way transmission of motion, that is, the motion of the rocker 4 can be transmitted to the rear wheel 14, but the motion of the rear wheel 14 does not affect the motion state of the rocker 4, so that the user can intermittently step on the rocker as needed plate 4.
