Problems solved by technology

[0004] Electric wheelchairs rely on electric energy to drive, and they inevitably need to continuously replenish electric energy. However, electric wheelchairs can only charge for a single time, so that the distance they can travel is also limited; in addition, the existing charging stations are not popular enough, and electric wheelchairs cannot replenish electric energy in time. It greatly limits the range of activities of the user, which is not conducive to the popularization and use of electric wheelchairs

Embodiment 1

[0031] In this embodiment, an electric wheelchair driven by hydrogen production by reforming methanol water is as figure 1 and figure 2 As shown, it includes a seat 1, a front wheel set 2 and a rear wheel set 3 arranged under the seat 1, the front wheel set 2 and the rear wheel set 3 are respectively connected with a motor 4, the motor 4 is connected with a manipulator 5, and the manipulator 5. A power supply device 6 is connected to control the power supply relationship between the power supply device 6 and the motor 4;

[0032] In this embodiment, the power supply device 6 includes a methanol water storage container 61, a delivery pump 62, a reforming chamber 63, a separation chamber 64, an electric heater 67, a fuel cell 65, and a starter 66. The starter 66 first starts the delivery pump 62 to deliver The methanol water in the storage container 61 is sent to the reforming chamber 63. At the same time, the starter 66 supplies power to the electric heater 67, and the electr...

Embodiment 2

[0042] This embodiment provides a method for driving an electric wheelchair driven by hydrogen production by reforming methanol water, including the following steps:

[0043] a. Turn on the starter, and the delivery pump 62 will deliver the methanol water in the methanol water storage container 61 to the reforming chamber 63; at the same time, the starter 66 supplies power to the electric heater 67, thereby heating the reforming chamber 63, so that the reforming chamber 63 The methanol water inside undergoes a reforming reaction to produce hydrogen to obtain a high-temperature mixed gas;

[0044] b. The resulting high-temperature mixed gas is transported to the separation chamber 64 to separate the hydrogen, and the hydrogen is transported to the fuel cell 65 and electrochemically reacts with the oxygen in the air in the fuel cell 65 to generate electric energy;

[0045] c. Part of the electric energy obtained is transmitted to the manipulator 5 to control the electric power s...

Abstract

The invention relates to the technical field of electric wheelchairs, in particular to an electric wheelchair capable of achieving charging driving through hydrogen production by reforming methanol water and a driving method of the electric wheelchair. The electric wheelchair structurally comprises a seat, a front wheel set and a rear wheel set, the front wheel set and the rear wheel set are arranged below the seat, and a motor is connected to the front wheel set and the rear wheel set and connected with a controller; the controller is connected with a power supply device, methanol water is used for producing hydrogen for power generation by the power supply device, the electric wheelchair can be recharged anytime and anywhere, and the driving range of the electric wheelchair is enlarged;according to the driving method, a starter starts a conveying pump to convey the methanol water to a reforming chamber, a reforming hydrogen production reaction is conducted, an electric heater is started for heating the reforming chamber, mixed gas is obtained to separate hydrogen, the hydrogen is used for power generation in a fuel battery, then produced electric energy is used for supplying power to the motor, the electric heater and the conveying pump, and continuous power supply is kept for the power supply device.

Description

technical field [0001] The invention relates to the technical field of electric wheelchairs, in particular to an electric wheelchair driven by hydrogen production by reforming methanol water and a driving method thereof. Background technique [0002] Wheelchairs are an important means of transportation for disabled people, patients and the elderly who have difficulty walking. Early wheelchairs relied on human hands to walk or patients turned the wheelchair to walk, but this way of walking was too dependent on others or very laborious. [0003] In order to overcome this problem, an electric wheelchair has appeared. The electric wheelchair has an intelligent control controller. As long as the user has a clear consciousness and normal cognitive ability, he can use the electric wheelchair to move by himself. , the sick and the elderly indispensable means of transport. In addition, with the development of a civilized society, the government has built more and more public facili...
