Problems solved by technology
Although the existing electric auxiliary device can assist the user to push the wheelchair, this kind of electric auxiliary device uses wireless transmission to transmit signals, so it is easy to be interfered by the external environment during the signal transmission process, and cannot transmit the signal to the control circuit reliably. Therefore, when the user pushes the wheelchair, the sensing signal cannot be correctly fed back to the control circuit to drive the motor, and assist the user to push the wheelchair
In addition, the structure of existing wheelchairs with assistive devices is too complicated, and the use of wireless transmission devices makes the cost more expensive

Embodiment Construction
[0056] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:
[0057] First, see Figure 1A and Figure 1B , is a structural schematic diagram and an exploded schematic diagram of a preferred embodiment of the auxiliary driving structure of the wheelchair of the present invention. As shown in the figure, the auxiliary driving structure of the wheelchair of the present invention includes a wired signal transmission structure 10, a sensor 20, a control circuit 30 and a driving unit 40 (see Figure 2A). The wired signal transmission structure 10 is arranged on a wheel hub 5 of the wheelchair 1, and the wheel hub 5 is arranged on a rotating wheel 3 of the wheelchair 1, and a lower housing 7 (see Figure 2A ) to match hub 5 (see image 3 ). The sensor 20 is arranged on the rotating wheel 3, and it...

The invention relates to an auxiliary driving structure of a wheel chair, comprising a wired signal transmission structure, a sensor, a control circuit and a control unit. The wired signal transmission structure is arranged on a hub, and the hub is arranged on a rotating wheel of the wheel chair, the sensor is arranged on the rotating wheel and generates a sensing signal to be transmitted to the wire signal transmission structure, the control circuit is coupled with the wire signal transmission structure and receives the sensing signal to generate a control signal, a driving unit is coupled with the control circuit and receives the control signal, and the hub is driven to rotate according to the control signal so as to rotate the rotating wheel. Thus, the aim of simple structure can be realized by applying the structure provided by the invention, a signal is transmitted in a wired transmission manner and is difficult to interfere by the external environment, the sensing signal can be really transmitted to the control circuit for accurately controlling the driving unit to rotate the rotating wheel, and the cost can be reduced as the wired transmission manner is adopted.
Description
technical field [0001] The invention relates to an auxiliary driving structure, in particular to an auxiliary driving structure of a wheelchair. Background technique [0002] Due to the advancement of medical technology, the average life expectancy of human beings has increased a lot. However, it is an indisputable fact that as human beings grow older, the functions of various organs of the body also age. When the human body suffers from a serious disease or becomes old and weak, it may be necessary to stay on the hospital bed for a long time , but lying on the hospital bed for a long time is definitely not a very good way for patients to recuperate, because long-term bed rest sometimes degrades body functions and even produces bedsores, and it has negative effects on cardiopulmonary function, large intestine peristalsis or urinary system. Therefore, in order to consider the patient's inconvenient movement and meet the needs of humanization, the elderly or other people who ...
