Description

Technical Field

[0001] The utility model relates to the technical field of electric wheelchairs, in particular to an electric wheelchair with a ventilation function. Background Art

[0002] With the continuous improvement of electric technology and the development of battery technology, electric wheelchairs have become more popular and practical. In the 1970s, with the commercial production of electric wheelchairs, they began to enter a wider market and became one of the main auxiliary tools for people with limited mobility. In recent years, with the development of material science, power technology and intelligent control systems, electric wheelchairs have become lighter, smarter and more comfortable. Modern electric wheelchairs have longer cruising range, higher performance and more optional functions, which can meet the needs and preferences of different users. Publication number: CN211067530U discloses an electric wheelchair, including: a wheelchair, a first mounting frame and multiple controllers. The first mounting frame is set on the armrest of the wheelchair. Multiple controllers have different types of control types, and any controller is fixed on the first mounting frame and electrically connected to the control part of the wheelchair. The electric wheelchair provided by the present application allows users to control the wheelchair using the corresponding controller according to their needs, which can meet the control requirements of different control environments and different groups of people, thereby increasing the scope of use of the product, improving the comfort of the product, and thus improving the market competitiveness of the product. In addition, when different users use the same wheelchair, different controllers can be used so that one wheelchair can be used by multiple users in turn. However, in the case of the above-mentioned device, the device has no ventilation structure, which may cause the user to sweat and feel uncomfortable after long-term use. At the same time, the battery and motor will generate heat after long-term use of the electric wheelchair, especially in a high temperature environment. If the electric wheelchair does not have sufficient ventilation structure, heat may accumulate inside the wheelchair, causing the electronic components to overheat, thereby causing damage to the device.
