Description

Chain pull dual-drive outdoor three-wheel exercise bike

Technical field

The utility model relates to an outdoor body-building sports car, in particular to a chain-driven outdoor three-wheel body-building car driven by chains and hands and feet.

Background technique

The utility model is a combined innovation of the existing bicycle technology and fitness equipment technology. At present, the outdoor three-wheeled exercise bike is driven by a pull type or does not move up and down without riding a horse, or the driving force cannot be applied to the hands and feet at the same time, or the saddle cannot move forward and backward, resulting in The cyclist can't coordinate the movement of the whole body to achieve the purpose of strengthening the body.

Contents of the invention

In order to solve the deficiencies of the prior art, the utility model provides a chain-pull outdoor three-wheel exercise bike with dual-drive hands and feet, which uses chain transmission to transmit power, uses hands and feet to drive simultaneously and coordinates the whole body to move.

The technical solution adopted by the utility model to solve its technical problems is: adopt three-wheel structure, one front wheel, two rear wheels, front wheel steering. The rear wheel is driven, and the whole exercise bike is basically a left-right symmetrical structure, including the car body part , Steering mechanism and driving mechanism, the car body part is composed of frame, guide rail, right rear wheel, left rear wheel, rear fork frame, rear bracket, bearing seat, rear bearing, drive shaft, saddle, pulley and saddle push rod The steering mechanism is composed of steering rod, handlebar, front fork and front wheel, and the driving mechanism is composed of driving arm, pedal leg, pedal, active flywheel, coil spring hinge, expansion rod, expansion sprocket, rear axle, Composed of flywheel and chain. In the car body part, the frame, the rear fork, the rear bracket and the guide rail form a fixed trapezoidal structure. The trapezoidal structure is double-layered and symmetrically distributed on the left and right sides. Rear bearing is installed in the seat, and rear wheel shaft is installed in the rear bearing, and the right end of rear wheel shaft is fixedly connected with right rear wheel, and the left end of rear wheel shaft is connected with left rear wheel by bearing, and left rear wheel can rotate on rear wheel shaft; The front end is equipped with a drive rod shaft, which hinges the frame and the drive arm in the drive mechanism. The guide rail has a certain inclination angle to the ground plane, the front is low and the rear is high. There is a saddle on the guide rail, and four One pulley, the pulley slides on the guide rail, the saddle is hinged to one end of the saddle push rod, the other end of the saddle push rod is hinged to the upper end of the driving arm, and the saddle push rod pushes the saddle to move back and forth on the slideway. In the steering mechanism, the steering rod is installed in the casing of the driving arm. The steering rod can be rotated in the casing of the driving arm. The upper end of the steering rod is fixedly equipped with a handlebar. The lower end of the steering rod is connected to the upper end of the front fork in the casing of the driving arm. The front wheel is installed at the lower end of the front fork; when the handlebar is rotated, the steering rod is driven to rotate in the casing of the driving arm, thereby linking the rotation of the front fork and the front wheel to realize the steering of the whole exercise bike. In the driving mechanism, the driving arm is hinged with the vehicle frame, and the driving arm rotates around the shaft of the driving rod. The lower end of the driving arm is fixedly connected with a pedal leg, and the two sides of the pedal leg are separated. The active flywheel is installed, and the active flywheel is a one-way sprocket that can only rotate clockwise; the pedal leg at the right pedal is provided with a coil spring hinge and is hinged with an expansion rod. The coil spring hinge is elastic and always drives the expansion The tightening rod rotates counterclockwise; the other end of the expanding rod is provided with an expanding sprocket, and a flywheel is installed on the rear wheel shaft, and the flywheel is a one-way sprocket that drives the rear wheel to rotate clockwise; the driving flywheel, the expanding sprocket, the flywheel and The chain constitutes a chain transmission. During work, the moving active flywheel drives the flywheel to rotate, and its center distance changes. The effect of the expansion rod and the expansion sprocket is to tighten the chain. When riding a bicycle, hold the handlebar with both hands and pull the driving arm backwards. At the same time, step on the pedals with both feet forward to make the driving arm rotate counterclockwise around the shaft of the driving rod. The forward movement of the pedal legs drives the active flywheel to move forward. At this time, the active The flywheel cannot rotate counterclockwise, so pull the chain to move forward, and the chain drives the flywheel on the rear wheel shaft to rotate clockwise, driving the rear wheel shaft and the right rear wheel to rotate clockwise, and the left rear wheel follows, driving the whole vehicle to move forward; at the same time, The saddle push rod pushes the saddle to move backward on the slideway, so that the driving arm can rotate to the maximum; when the driving arm returns, the driving arm rotates clockwise, so that the hands and feet can relax the driving arm. At this time, the saddle is under the action of gravity The bottom slides forward along the guide rail (the front of the guide rail is low and the rear is high), and the saddle pushes the driving arm to rotate clockwise through the saddle push rod, so that the driving arm returns to its position, completing the return journey of the driving arm, and also completing a stroke of the driving arm, and repeatedly driving the arm The stroke can drive the exercise bike to move forward continuously.

The beneficial effect of the utility model is that the driving force applied to hands and feet at the same time can reasonably distribute the driving force of hands and feet according to the needs, and the hands and feet and the whole body move up and down when riding a bicycle, so as to achieve the purpose of fitness and entertainment, and the movements of the whole body are coordinated and reasonable The effect of using the three-wheel structure can increase the stability and safety of the exercise bike. The utility model can also be used as a walking tool, and the operation is simple and convenient.
