Detailed ways

The utility model is described in detail below in conjunction with accompanying drawing:

Please refer to shown in Fig. 1, the utility model sun car (elderly) comprises an electric tricycle 1 for the elderly, a solar panel 3 installed on the roof, a support 2 for fixing the solar panel 3, installed below the solar panel 3 The solar charging controller 4 is installed in the battery 5 under the front seat, the brushless DC motor controller 6 is installed under the front seat, and the brushless DC motor 7 for driving the rear wheel.

Please refer to FIG. 2 , the circuit part includes a solar panel 3 , a current-limiting diode 8 , a solar charge controller 4 , a storage battery 5 , a brushless DC motor controller 6 , and a brushless DC motor 7 . The current limiting diode 8 and the ammeter 9 are connected in series between the solar panel and the solar charge controller, and the storage battery 5 is connected to the output terminal of the solar charge controller.

The electric tricycle 1 for the elderly is a mature vehicle on the market, with front and rear double rows of seats, the vehicle length is greater than 2 meters, the width is greater than 0.8 meters, and the maximum speed is 30 kilometers per hour, which is convenient for assembling the bracket 2.

The support 2 is welded with a 1MM thick 20*20 stainless steel square tube, and its four columns are fixed on the tricycle, and the size of the top matches the size of the solar panel.

The length and width of the solar battery panel 3 are less than or equal to the length and width of the elderly electric tricycle, the power is greater than or equal to 200W, and the open circuit voltage is greater than 72V, which can charge the 48V battery 5 .
