Problems solved by technology

[0004] In order to solve the defects of existing pedal cars such as inability to control direction and turn, slow forward speed, inability to keep free sliding, inability to fold and poor stability, the present invention provides a new type of foldable three-wheel pedal bike with a rotating speed amplifying device , change the rolling bearing of the rear wheel to a one-way rolling bearing, install a speed amplification device on the drive shaft, so as to achieve the purpose of increasing the forward speed and maintaining free sliding, and optimize the structure design of the car body. The handlebar adopts telescopic height adjustment and folding The design ensures high applicability and portability. In addition, the four-wheel design is changed to three-wheel design, which increases the stability and flexibility of the body.

Embodiment 1

[0016] Said a new type of foldable three-wheeled bicycle with speed amplifying device, the upper end of the handlebar riser 4 is connected with the horizontal handlebar 1, and the lower end is connected with the U-shaped front fork 10, and the U-shaped front fork 10 is connected with the front wheel 8 The horizontal handlebar 1, the handlebar riser 4, the U-shaped front fork 10 and the front wheel 8 are fixed together from top to bottom, and the torque of turning the horizontal handlebar 1 is transmitted through the handlebar riser 4. To front wheel 8, thereby reach the function that stepping on bicycle realizes turning.

Embodiment 2

[0018] Said a new type of foldable three-wheeled bicycle with rotating speed amplifying device, the handlebar standpipe 4 is divided into upper and lower two section standpipes, the outer diameter of the upper standpipe is equal to the inner diameter of the lower standpipe, and the upper standpipe is socketed Inside the lower standpipe, a height adjustment device 5 is provided at the connection between the upper standpipe and the lower standpipe. By adjusting the height of the upper standpipe and fixing it with the height adjustment device 5, the purpose of adjusting the height of the horizontal handlebar 1 is achieved. Adapt to the needs of children of different heights.

Embodiment 3

[0020] Described a kind of novel foldable three-wheel pedaling vehicle with rotating speed amplifying device, wheel shield 11 is fixed on the inside of U-shaped front fork 10, and wheel shield 11 plays the effect of blocking muddy water on the one hand, on the other hand, installs The brake 2 located on the horizontal handlebar 1 is connected to the wheel guard 11 through the brake cable 3, and the brake cable 3 passes through the brake return spring 7. When the brake 2 is pinched by hand, the wheel guard 11 and the front wheel 8 rub against each other. Play a braking effect.

Abstract

The invention discloses a novel folding three-wheeled pedaling bicycle with a rotating speed amplifying device. The bicycle adopts a triangular layout structure of a front wheel and two rear wheels, handlebars adopt a height adjustable folding design, a brake and a wheel guard plate are mounted, a pedal is designed to be divided into left and right double pedals, the pedal is connected with a bodybeam by a Z-shaped connecting rod, a driving shaft transmits a pedaling torque to the rear wheels to achieve the purpose of driving forward, the rotation speed amplifying device is mounted on the driving shaft to increase the forward speed when the pedal is stepped, the driving shaft and a pinion gear are connected through a one-way rolling bearing, a power transmission function is achieved whenthe pedal is stepped, and a free sliding state is ensured when the pedal is not stepped.

Description

technical field [0001] The invention belongs to the field of children's toy car manufacturing, and in particular relates to a novel foldable three-wheel treadmill with a rotational speed amplifying device. Background technique [0002] The existing children's treadmill has simple structure and single function, and there are many unreasonable places in design. For example, the Chinese invention patent with the notification number CN106563248A announced "a new type of children's treadmill". First of all, this children's treadmill does not have a direction control device and cannot control the direction. It can only move forward or backward along a straight line. To make a turn, you need to get on and off frequently when using it. Secondly, the forward speed is relatively slow when pedaling, and it can only keep moving forward under the continuous pedaling state. Once the pedaling stops, it will stop immediately, and the effect of free gliding cannot be achieved. [0003] In ...
