Abstract

The utility model discloses a solar energy electrically powered wheelchair which comprises a wheelchair body, a wheel hub motor, a steering speeder, a driving wheel and guiding wheels. Power is supplied to the wheel hub motor through a storage battery and the wheel hub motor drives the driving wheel to rotate. The solar energy electrically powered wheelchair is characterized by comprising solar cell panel sets, wherein the solar cell panel sets are arranged above the wheelchair body and the solar cell panel sets charge the storage battery through a controller for electric energy storage. The number of the solar cell panel sets is three and the solar cell panel sets are arranged over the wheelchair body. A first auxiliary solar cell panel set and a second auxiliary solar cell panel set are arranged on the upper surface of a main solar cell panel set through auxiliary cell panel driving devices, wherein the first auxiliary solar cell panel set and the second auxiliary solar cell panel set can be unfolded or folded in a back-and-forth mode. The solar energy electrically powered wheelchair is charged through solar energy, simple and convenient to operate, wide in applied crowd, safe to use, meanwhile energy-saving and environment-friendly.

Description

A kind of solar energy electric wheelchair

Technical field

This utility model relates to a kind of medical rehabilitation assistive device.

Background technology

Current, Chinese aging problem is more and more serious, the inconvenience that is slow in action of old man's legs and feet, and go off daily need have the entourage; Simultaneously, China is the maximum country of people with disability's quantity, and the people with disability's articles for use instrument on the existing market can not satisfy their consumer need.Along with the progress and development of society, old man and people with disability are more and more stronger to the serious hope of living on one's own life in recent years, especially independent trip, and therefore, society is more and more vigorous to the demand of walking-replacing tool.

The utility model content

The purpose of this utility model provides a kind of solar energy electric wheelchair, and this solar energy electric wheelchair is safe and convenient to use, and energy-conserving and environment-protective are fit to old man and people with disability's go off daily very much.

To achieve these goals, adopt following scheme: a kind of solar energy electric wheelchair, comprise wheelchair car body, wheel hub motor, turn to arrangements for speed regulation, driving wheel and directive wheel, accumulator is powered to wheel hub motor, the rotation of driving driving wheel, it is characterized in that: described solar energy electric wheelchair comprises solar panel, and wherein solar panel is arranged on wheelchair car body top; Solar panel charges a battery by controller, store electrical energy.

Described solar panel has 3 groups, solar energy main battery plate group arranges directly over the wheelchair car body, the first secondary cell plate group and the second secondary cell plate group are arranged at the upper surface of solar energy main battery plate group by secondary cell plate driving device, wherein the first secondary cell plate group and the second secondary cell plate group can before and after launch or folding.

Describedly turn to the place ahead on right handrail that arrangements for speed regulation are arranged on the wheelchair car body or the left handrail.

Described accumulator is arranged on wheelchair car body below, and described controller is arranged on the wheelchair car body back lower place.

When solar energy electric wheelchair non-charging mode and 220V domestic alternating current charging, the folding of two secondary cell plate groups is above the main battery plate; When the solar charging power mode, two groups of secondary cell plate groups are under the driving of respective drive device, and two groups of secondary cell plate groups are launched in the both sides, front and back of main battery plate; After charging finished, folding was above main battery plate group automatically.The solar energy electric wheelchair in motion, solar panel is to charge in batteries, during stagnation of movement, controller determines whether charge according to intensity of illumination, only in intensity of illumination during greater than setting value, the charging of two secondary cell plate developments.

Described controller can be charge in batteries by domestic 220V alternating current power supply also.

This utility model adopts solar energy that wheelchair is powered, and it is easy and simple to handle, and it is wide to be suitable for the crowd, uses safety, energy-conserving and environment-protective simultaneously.

Fig. 6 is the vertical view of Fig. 5.

Among the figure, 1 is wheel hub motor, and 2 is driving wheel, 3 is the wheelchair car body, and 4 are auxiliary push arm, and 5 is the first secondary cell plate group, 6 for turning to arrangements for speed regulation, and 7 is controller, and 8 is brake lever, 9 is accumulator, 10 is directive wheel, and 11 for foot-operated, 12 secondary cell plate driving devices, part 13 is solar energy main battery plate group, and 14 is the second secondary cell plate group.

The specific embodiment

Below in conjunction with the drawings and specific embodiments this utility model patent is described further.

As depicted in figs. 1 and 2, solar energy main battery plate group 13 is arranged on wheelchair car body 3 tops, and the first secondary cell plate group 5 and the second secondary cell plate group 14 are separately positioned on solar energy main battery plate group 13 tops.

Extremely shown in Figure 6 as Fig. 3, the solar energy electric wheelchair is when utilizing the solar recharging operation, be folded in solar energy main battery plate group 13 tops two secondary cell plates group and launch under the driving effect of corresponding secondary cell plate driving device 12, solar energy main battery plate group 13 and two secondary cell plate groups are by 9 chargings of controller 7 accumulators.

After the charging end of job or electric wheelchair when travelling, controller 7 is by control secondary cell plate driving device 12, folding two secondary cell plate groups.

During the walking of solar energy electric wheelchair, controller 7 turns to arrangements for speed regulation 6 signal controlling drive hub motors 1 to rotate by detection, and realizes turning to function by the speed discrepancy of two driving wheels 2 about control.

During the walking of solar energy electric wheelchair, the solar energy main battery plate group 13, the first secondary cell plate group 5 and the second secondary cell plate group 14 that are arranged on wheelchair car body 3 tops hide functions such as rain, sunshade in addition; During the charging of solar energy electric wheelchair, can also be that power supply passes through 9 chargings of controller 7 accumulators with domestic 220V alternating current.

The solar energy electric wheelchair, easy and simple to handle, it is wide to be suitable for the crowd, uses safety, energy-conserving and environment-protective simultaneously.
