Problems solved by technology

Electric wheelchairs in the traditional sense have a large radius of gyration, which is not suitable for indoor operation in a small space. Compared with electric wheelchairs in the traditional sense, electric wheelchairs equipped with three or four Mecanum wheels have the advantages of indoor operation. Severe slipping, poor controllability, and noise, not suitable for the elderly and disabled

Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings.

[0040] The omnidirectional mobile device of the present invention comprises a driving chassis 1, a slewing mechanism 2, and a supporting chassis 3, such as figure 1 As shown, the upper and lower ends of the slewing mechanism 2 are connected to the supporting chassis 3 and the driving chassis 1 respectively.

[0041] The drive chassis 1 includes a drive platform 101, a drive motor A102, a drive motor B103, a drive gear A104, a drive gear B105, a drive gear A106, a drive gear B107, a drive shaft A108, a drive shaft B109, a driving wheel A110, and a driving wheel B111, Such as figure 2 shown.

[0042] Wherein, the driving platform 101 is a truss structure, thereby saving materials and reducing manufacturing costs. Drive motor A102 and drive motor B103 are installed on two opposite sides of the upper surface of drive platform 101 respectively, and the output shafts of ...

Abstract

The invention discloses an omnidirectional mobile device for an electric wheelchair, comprising a driving chassis, a swing mechanism and a supporting chassis, wherein a driving gear is installed on the supporting chassis, and the supporting chassis plays a role in supporting; a direction locking caster is arranged on the driving chassis, and the swing mechanism is used for connecting the supporting chassis and the driving chassis and causing the driving chassis to move axially along the swing mechanism. The omnidirectional mobile device for the electric wheelchair implements three modes of linear motion, curvilinear motion and side moving motion through cooperation of the direction locking caster and the driving gear. And the omnidirectional mobile device for the electric wheelchair has the following advantages: the omnidirectional mobile device can implement omnidirectional flexible movement, and has a function of implementing omnidirectional motion without turning radius; the omnidirectional mobile device is high in load capacity, non-slipping, high in controllability, quiet, high in reliability and low in production cost.

Description

technical field [0001] The invention relates to the field of service robots, specifically, an omnidirectional mobile device for electric wheelchairs Background technique [0002] The International Federation of Robotics (IFR) has a preliminary definition of service robots: a service robot is a semi-autonomous or fully autonomous robot that can complete services that are beneficial to human health, but does not include equipment engaged in production. [0003] With the development and progress of social civilization, ensuring and improving the quality of life of vulnerable groups such as the elderly and the disabled has attracted more and more attention from people from all walks of life. A large number of studies have shown that effectively enhancing the mobility of the elderly and the disabled not only facilitates their daily life, but also has a profound impact on their mental health, self-evaluation, and mental state. [0004] For the elderly and disabled people with poo...
