Embodiment Construction

[0022] The specific implementation manner of the present invention will be described in further detail below in conjunction with the accompanying drawings. Such as figure 1 , figure 2 , image 3 As shown, a new type of stair climbing electric wheelchair mainly includes front wheel motion system 1, rear wheel motion system 2, steering handle 3, seat 4, shock absorber 5, pedal 6, chain 7, front and rear connecting rods 8, Composed of fixed shaft 9, hinge 10, cylinder 11, power supply 12, and rotating shaft 13, the motion of the front wheel motion system 1 is the main motion, and the motion of the rear wheel motion system 2 is the secondary motion. When the stair climbing electric wheelchair moves on flat ground , only the main movement is turned on, that is, only the front wheel movement system 1 is moving, and the front wheel adopts a triangular synchronous belt mechanism. There is a synchronous wheel in the middle of the synchronous belt 1-2, that is, the center wheel 1-4,...

Abstract

The invention discloses a new type of electric wheelchair for climbing stairs. The components include: front wheel motion system (1), rear wheel motion system (2), steering handle (3), seat (4), shock absorber ( 5), pedal (6), chain (7), front and rear connecting rod (8), fixed shaft (9), hinge (10), cylinder (11), power supply (12), rotating shaft (13); front wheel movement The movement of the system (1) is the main movement, and the movement of the rear wheel movement system (2) is the auxiliary movement. The main movement and the auxiliary movement cooperate with each other, so that the stair climbing electric wheelchair can not only move on the flat ground, but also realize the stair climbing movement , In the two sports, it also includes a shock absorber, a center of gravity adjustment device, and a steering device.

Description

technical field [0001] The invention belongs to the field of electric wheelchairs, and relates to a novel structural design of an electric wheelchair for climbing stairs, which is applied to the daily life of middle-aged and elderly people and people with leg disabilities in the field of life. Background technique [0002] The stair-climbing electric wheelchair is mainly used to help the elderly, infirm, and disabled people go up and down the stairs. With the rise of the domestic pension industry, the stair-climbing electric wheelchair has gradually been paid attention to. There is no small size, simple control, low price, and applicable in China. For the stairs of ordinary residents and the stair-climbing electric wheelchairs for the disabled and the elderly, manufacturers are now constantly competing with each other, increasing research and development efforts, and continuously improving product quality. [0003] There are two types of stair climbing electric wheelchairs o...
