What parts are electric wheelchairs made of?

The electric wheelchair is mainly composed of the following parts, the main body frame, the controller, the motor, the battery, and other accessories such as the seat back cushion. Next, we need to understand each part of the accessories separately.

In this issue, let’s first understand the main frame and controller:
1. Main frame: The main frame determines the structural design, external width and seat width of the electric wheelchair. External height, backrest height, and designed functionality, the main material can be divided into steel pipe, aluminum alloy, and aviation titanium alloy,

Most of the steel pipes and aluminum alloys are common in the market. The cost of steel pipes is relatively low, and the load-bearing capacity is not bad. The disadvantage is that they are bulky, easy to rust and corrode when exposed to water and humid environments, and the service life will be shortened over time.

At present, most of the mainstream materials have adopted aluminum alloy, which is lighter and relatively corrosion-resistant. The material strength, lightness, and corrosion resistance of aerospace titanium alloys are better than the first two, but due to the cost of materials, currently the main It is applied to high-end and portable electric wheelchairs, and the price is also more expensive.

In addition to the material of the main body frame, it is also necessary to observe the details of other components of the car body and the welding process, such as: the material of all accessories, the thickness of the material, whether the details are rough, whether the welding points are even, and the denser the welding points, the better. , the arrangement rules are similar to fish scales is the best, also known as fish scale welding in the industry, this process is the strongest, if the welding parts are uneven, or there is leakage of welding, safety hazards will gradually appear over time. The welding process is an important link to observe whether a product is produced by a large factory, whether it is serious and responsible, and produces products with quality and quantity.

2. Controller: The controller is the core component of the electric wheelchair, just like the steering wheel of a car. Its quality directly determines the handling and service life of the electric wheelchair. The controller is generally divided into: upper controller and lower controller.

Most imported brand controllers are composed of upper and lower controllers, while most domestic brands only have upper controllers. The most widely used imported controller brand is British PG. Comparing domestic products with imported ones, the imported ones are better, and the cost price is also higher than that of domestic products. Imported products are generally equipped on medium and high-end electric wheelchairs.

So how to simply check the quality of the controller? There are two things you can try:
1. Turn on the power switch, push the controller, and feel whether the start is stable; release the controller, and feel whether the car stops immediately after a sudden stop.
2. Control and rotate the car on the spot to feel whether the steering is stable and flexible.
