Description
Technical field
The utility model relates to a kind of emergency set that is used for battery vehicle.
Background technology
Serious day by day along with environmental pollution, people's environmental consciousness improves constantly, and low-carbon (LC), green life style become the main flow of life gradually, and battery vehicle is with its light, laborsaving important trip instrument that becomes people all the more.
Yet, riding battery vehicle when trip, can occur near the destination, the situation of electric weight deficiency because the electric weight deficiency can't provide stable voltage, makes that the parts of battery vehicle inside can't operate as normal, has to pushing away battery vehicle and advances.
The utility model content
The purpose of this utility model is to provide a kind of emergency set that is used for battery vehicle, still can operate as normal when battery vehicle is under-voltage.
The utility model provides a kind of emergency set that is used for battery vehicle, comprise voltage detecting circuit and booster circuit, the input of described voltage detecting circuit links to each other with the battery vehicle battery, the output of described voltage detecting circuit links to each other with the control end of described booster circuit, the input of described booster circuit links to each other with the output of described battery vehicle battery, and the output of described booster circuit links to each other with the input of described battery vehicle battery.
Further, also comprise velocity checking circuits, the input of described velocity checking circuits links to each other with the handle of battery vehicle, and the output of described velocity checking circuits links to each other with the control end of described booster circuit.
Further, also comprise power source indicating device, described power source indicating device is installed in the headstock of battery vehicle, and the input of described power source indicating device links to each other with the output of described voltage detecting circuit.
Further, described booster circuit is integrated in the DC brushless motor controller of described battery vehicle.
Further, described velocity checking circuits is three fast selection wires.
Adopt the emergency set that is used for battery vehicle of the present utility model, voltage detecting circuit detects the battery vehicle battery electric quantity, when the battery vehicle electric weight is not enough, voltage detecting circuit sends signal, the voltage of booster circuit control battery vehicle battery remains on the state that the parts of battery vehicle inside can operate as normal, realize when battery vehicle is under-voltage still can operate as normal purpose.
Description of drawings
Fig. 1 is the circuit diagram that the utility model is used for the emergency set of battery vehicle;
Fig. 2 is the structural representation that the utility model is used for the emergency set of battery vehicle.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model embodiment is done further and to be elaborated.
See also Fig. 1, a kind of emergency set that is used for battery vehicle, comprise voltage detecting circuit 11 and booster circuit 12, the input of described voltage detecting circuit links to each other with the battery vehicle battery, the output of described voltage detecting circuit links to each other with the control end of described booster circuit, the input of described booster circuit links to each other with the output of described battery vehicle battery, and the output of described booster circuit links to each other with the input of described battery vehicle battery.
Adopt the emergency set that is used for battery vehicle of the present utility model, voltage detecting circuit detects the battery vehicle battery electric quantity, when the battery vehicle electric weight is not enough, voltage detecting circuit sends signal, the voltage of booster circuit control battery vehicle battery remains on the state that the parts of battery vehicle inside can operate as normal, realize when battery vehicle is under-voltage still can operate as normal purpose.
Further, also comprising can power source indicating device, and described power source indicating device is installed in the headstock of battery vehicle, and the input of described power source indicating device links to each other with the output of described voltage detecting circuit.When the battery vehicle battery electric quantity was not enough, power source indicating device can remind the drivers in time to charge.
See also Fig. 2, further, can also comprise velocity checking circuits, the input of described velocity checking circuits links to each other with the handle of battery vehicle, and the output of described velocity checking circuits links to each other with the control end of described booster circuit.Voltage detecting circuit can be the under-voltage selection wire 21 of folk art term, and velocity checking circuits can be three fast selection wires 22.The speed of three kinds of gears of the corresponding battery vehicle of three fast selection wires at different speed, can select booster circuit that the voltage of battery vehicle battery is remained on different magnitudes of voltage, thereby realizes the operate as normal of battery vehicle under under-voltage situation.
Booster circuit can be integrated in the DC brushless motor controller 23 of described battery vehicle.
The above only is an embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
