Abstract
The utility model discloses an electric vehicle which comprises a front wheel, a rear wheel and two sets of independent power supply batteries, wherein both the front wheel and the rear wheel are provided with a driving motor; the two sets of power supply batteries are connected in parallel on a power supply circuit through independent on-off switches; the two driving motors are connected on the power supply circuit through a series circuit and a parallel circuit; and each circuit is provided with an independent control switch. Both the front wheel and the rear wheel of the electric vehicle are provided with the driving motors and three driving modes, i.e. a front-wheel driving mode, a rear-wheel driving mode and a double driving mode, are realized by circuit control so as to greatly improve the driving capacity and the application range of the electric vehicle for meeting the requirements of different road conditions. Moreover, by the arrangement of the two sets of power supply batteries, the continuation capacity of the electric vehicle is greatly improved and the stroke of the electric vehicle is increased.
Description
Technical field
The utility model relates to a kind of battery-driven car.
Background technology
All there are problems such as under power, travelled distance weak point, battery weak point in service life in existing battery-driven car, and it directly brings a lot of inconvenience to the user, particularly in the mountain area, because road conditions are bad, caused especially and has used the stage of replacement of inconvenience and battery too fast.And the front-wheel of existing battery-driven car all is flower wheels, promotes front-wheel by trailing wheel and travels, and this causes has increased by 20% resistance in the process of moving.Example: as next 350W unit (rear-guard) battery-driven car, cruising is (at same weather, the same windage, the same road conditions) under the situation, the electric current that travels is that the battery-driven car of 8A-9A. and two 350W two-shippers (two driving) is with under the above-mentioned the same situation, its electric current that travels is 6A-6.5A, that is to say, directly energy-conservation reaching about 30%.
The utility model content
At the problem that prior art exists, the purpose of this utility model is to provide a kind of front-wheel, trailing wheel to be driving wheel, to improve the actual in-use performance of wheel, satisfies the battery-driven car in-use performance of different road conditions.
For achieving the above object, the utility model battery-driven car, comprise front-wheel, trailing wheel and two groups of independently-powered batteries, wherein, be provided with drive motor on front-wheel and the trailing wheel, two groups of supplying cells are via independently being connected in parallel on the feed circuit behind the on and off switch, and two drive motor are connected on the feed circuit by circuit series, circuit parallel, are provided with independently master cock on each circuit.
Further, on two described drive motor all separate configurations be connected with auto mat, described drive motor is connected on the described feed circuit after via auto mat.
Further, be connected with control circuit between two described auto mats, this control circuit is provided with three power conversion switch and signal controllers.
The utility model battery-driven car is by all being provided with drive motor on front-wheel and trailing wheel, and three kinds of drive forms of f-w-d, back-wheel drive, two drivings have been realized by circuit control, thereby the power-handling capability and the Applicable scope of battery-driven car have been improved greatly, to adapt to the demand of different road conditions.And, by two groups of supplying cells are set, will improve the flying power of battery-driven car greatly, increased the stroke of battery-driven car.
Description of drawings
Fig. 1 is the utility model electrical block diagram.
The specific embodiment
As shown in Figure 1, the utility model battery-driven car, comprise front-wheel, trailing wheel and two groups of independently-powered batteries, wherein, front-wheel is provided with before driving motor 1, and trailing wheel is provided with 2, the first groups of supplying cells 3 of rear drive motor and is connected in parallel on the feed circuit 5 after via first on and off switch 4, second group of supplying cell 6 is connected in parallel on the feed circuit 5 after via second on and off switch 7
Before driving motor 1 and rear drive motor 2 are connected on the feed circuit 5 by circuit series, circuit parallel, are provided with independently master cock on each circuit.
Separate configurations is connected with first auto mat 8 and by being connected on the feed circuit 5 behind first auto mat 8 on the before driving motor 1; Separate configurations is connected with second auto mat 9 and by being connected on the feed circuit 5 behind second auto mat 9 on the rear drive motor 2.
Be connected with control circuit 10 between first auto mat 8 and second auto mat 9, control circuit 10 is provided with three power conversion switches 12 and signal controller 11.
During use:
When 1, before driving motor 1 and rear drive motor 2 are worked simultaneously, the switch 13 and second on and off switch 7 are all merged;
2, before driving motor 1 is worked, when rear drive motor 2 is not worked, then switch 13 is merged, and second on and off switch 7 disconnects.All right conversely when not working as rear drive motor 2 work front motors.
3, when wherein one group when not having power supply of two Battery packs, please first on and off switch 4 is merged, disconnect promptly opposite.
When 4, charging, so, at this moment will disconnect first on and off switch 4, to reach electrically-charged separately purpose owing to be that double cell is furnished with 2 chargers.
Through after the above-mentioned improvement, the utility model battery-driven car has the following advantages:
1, front and back wheel all is driving wheel original one before and after moving becoming, and so the resistance at former front driven wheel about 20% under the specific road conditions has also just reduced simultaneously.
Also will significantly reduce the resistance of former unit work when 2, the front and back motor is worked simultaneously, resistance is littler when particularly climbing, two motors all are in the light motoring condition of half load during flat pavement running, and double-motor sends double even bigger power simultaneously during climbing, thereby it is as though walking upon flat ground to reach climbing.
3, controller can be worked simultaneously and also can be worked independently, and is controlled by signal controller when working simultaneously, can not occur that double-motor is worked simultaneously, nonsynchronous phenomenon.
4, two Battery packs can singly be organized to two motor power supplies, also can power one to one, can also give two motor power supplies simultaneously by two Battery packs, and simultaneously two Battery packs also can be given single motor power supply.
5, because a battery-driven car has two Battery packs to give two motor power supplies, so the discharge current when using two Battery packs to travel has only former 35%～40% during with power, the minimizing of battery discharge current will prolong its service life, to improve the flying power of battery-driven car greatly, increased the stroke of battery-driven car.
