Description

A stair-climbing scooter for the elderly

Technical field

The utility model relates to the field of scooters for the elderly, and in particular to a scooter for the elderly that can climb stairs.

Background technique

The elderly mobility scooter, also known as the elderly electric vehicle or the elderly power-assisted vehicle, is an ideal vehicle for the elderly to travel outdoors. It has stable performance, relatively slow speed, uses electricity, and does not require refueling, so it is also called an environmentally friendly elderly vehicle.

Most of the common stair-climbing scooters on the market for the elderly use crawler mechanisms at the bottom of the stair-climbing structure. The crawler mechanisms operate loudly and can only climb a single slope. They cannot be used for spiral stairs and stairs with changing slopes. Climbing; the shock absorption performance of the crawler tracks is not good, and if you encounter rough roads, the bumps will be obvious.

Utility model content

The technical problem to be solved by this utility model is to provide a stair-climbing scooter for the elderly to overcome the above-mentioned deficiencies in the prior art.

The technical solution of the utility model to solve the above technical problems is as follows: a stair-climbing scooter for the elderly, including a backrest, a seat plate, a shock-absorbing box, a support rod, a walking mechanism, a support module, two handrails and a controller. The seat plate is arranged horizontally, with a backrest fixed vertically at one end of the seat plate, and two handrails are respectively provided on both sides of the backrest, and the bottom end is fixed to the seat plate; a shock-absorbing box is provided at the bottom of the seat plate, and a support rod is fixed at the bottom of the shock-absorbing box , there is a traveling mechanism at the bottom of the support rod. The traveling mechanism includes a motor, multiple telescopic modules and a rubber anti-slip ring. The bottom end of the support rod is rotationally connected to the motor. Multiple telescopic modules are arranged in a circle with the motor as the axis. The telescopic modules are connected to the rubber anti-slip rings on the outside. A fender is fixed at one end of the bottom of the seat plate. A support module is fixed on both the fender and the bottom of the seat plate. There are passages between the controller, the traveling mechanism and the support module. The wires are connected and cooperate with each other to complete the climbing process.

The beneficial effects of the utility model are: pushing the push rod at the top of the controller, the motor, the fender and the support module at the bottom of the seat plate are started, the motor rotates, driving multiple telescopic modules outside the motor to rotate, and at the same time, the bottom of the telescopic module The rubber anti-skid ring on the outside of the end is also in contact with the stairs. Due to the action of the stair steps, the rubber anti-skid ring deforms and dents toward the direction of the motor. The telescopic module also shrinks inward. When the step is grasped, the motor continues to rotate. Different telescopic modules and rubber The circles are dented, restored, and rolled on the stairs in sequence. When the motor rotates, the support modules on the bottom plate are fixed to different steps to prevent the elderly mobility scooter from rolling backwards. At the same time, the seat plate and backrest of the mobility scooter are always secure. In the vertical state, due to the contraction effect of the telescopic module and the rubber anti-slip ring, the mobility scooter for the elderly rises smoothly, providing a good driving experience and safer.

The above method has the following further beneficial effects: when encountering external steps, the second spring gradually contracts inwards due to the squeezing of the steps, and the rotating gasket rotates in the rubber anti-slip ring, thereby reducing the reaction force while increasing the contact area with the stairs, increasing the grip, and preventing the elderly mobility scooter from tipping over backwards.

Further, a plurality of first springs are vertically fixed in the shock-absorbing box. The bottom ends of the plurality of first springs are fixed to the support rods through first slide blocks. The first slide blocks are slidingly connected to the inner wall of the shock-absorbing box. The bottom of the first slide blocks The end is fixed to the support rod.

The further beneficial effect of adopting the above is that the first spring in the shock absorbing box can further reduce the force transmitted from the support rod and improve the riding comfort.

Further, the support module includes a fixed block, an electric push rod, a support column, a DC forward and reverse motor and a support roller. There is a chute in the fixed block, the electric push rod is set at the bottom of the chute, and the output rod of the electric push rod and the support The column is fixed, and the support column is slidingly connected to the inner wall of the chute. The bottom end of the support column is provided with a DC forward and reverse motor, and a support roller is connected to the DC forward and reverse motor for rotation.

Further, several pressure sensors are provided on the outside of the support roller, and the support roller is rotatably connected to the output shaft of the DC forward and reverse motor. The pressure sensors and the DC forward and reverse motor are connected to the controller through wires.

The further beneficial effects of using the above are: the controller determines the stress of the support roller and the support column through the signal on the pressure sensor, changes the extension length of the electric push rod, and always keeps the support roller in contact with the surface of the step to play a supporting role. , at the same time, the DC forward and reverse motor makes the rotation direction of the support roller consistent with the direction of motor rotation, preventing the support roller from slipping on the step and reducing the risk of accidents.

Further, a push rod is fixed to the top of the backrest.

The further beneficial effect of adopting the above-mentioned method is that when the elderly with inflexible fingers are riding, they can be pushed forward by others.
