Description

2265240 1 A SAFETY APPARATUS FOR AN ELECTRIC VEHICLE
BACKGROUND OF THE INVENTION
The present invention relates -to a safety apparatus for an electric vehicle travelling by an electric driving power.
Fig.2 is a diagram illustrating a power circuit of an electric driving system according to the conventional invention. The electric driving system is provided with a battery 1 acting as a driving power source of the electric vehicle, a fuse 2 preventing a short circuit accident. of the. power circuit, a control apparatus 3 controlling a current from the battery 1, and a motor 4 controlled by the control apparatus 3, in which the motor 4 is linked with a driving apparatus of the vehicle not shown in Fig. 2.
An operation of the conventional apparatus is described as follows. The current supplied from the battery 1 passes through the fuse 2, and then is transmitted into the control apparatus 3. Further, the current controlled by the control apparatus 3 drives the motor 4, so that the driving power produced by the motor drives the driving appaxatus (not shown in Fig. 2) of the vehicle linked with the motor 4.
When the power circuit is short-circuited, a large amount of current is transmitted into the fuse 2, and then the fuse 2 is molten, so that the current of the power circuit is broken, thereby to keep a safety of the electric vehicle.
R However, since the safety apparatus f or the electric vehicle according to the conventional invention is constructed by only the fuse 2, the fuse cannot break the power circuit as far as which is not short-circuited in case that a collision accident of the vehicle occurs. Therefore, there is a problem that the current undesirably continues to being supplied into the motor 4 in regardless of a state of the vehicle or a driver of the vehicle, thereby to have the vehicle traveled continuously.
SUMMARY OF THE INVENTION
With the above problem and difficulty accompanying the conventional safety apparatus in view, an object of the present invention is to provide a safety apparatus for an electric vehicle which a driving power source is securely broken when a collision accident of the vehicle occurs, thereby to prevent the vehicle from traveling further.
To achieve the above object, according to the present invention, the safety apparatus for the electric vehicle is provide with a switch device breaking between the driving power source and a motor in accordance with an acceleration produced when the collision accident of the vehicle occurs, thereby to stop supplying the motor with a driving power so as to prevent the vehicle from travelling further.
3 BRIEF DESCRIPTION OF THE DRAWINGS
In the accompanying drawings; Fig. 1 is a diagram illustrating a power circuit system connecting a safety apparatus for an electrical vehicle according to a first embodiment of the present invention; and Fig. 2 is a diagram illustrating a power circuit system according to a conventional apparatus.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Components of reference numerals 1-4 in Fig. 1 are omitted to describe because of the same components as a conventional apparatus. A breaker 5 is connected between a battery 1 and a control apparatus 3. An acceleration sensor 6 provides the breaker 5 with an electric signal by detecting an acceleration produced when a collision accident of an electric vehicle occurs.
An operation of the first embodiment is described, referring to Fig. 1. A current supplied from the battery 1 passes through a fuse 2 and the breaker 5, and then is transmitted into the control apparatus 3. The 'current controlled by the control apparatus 3 is supplied into the motor 4, thereby to drive the motor 4. Therefore, a driving power produced by the motor 4 drives a driving apparatus (not shown in Fig. 1) of the electric vehicle linked with the motor 4.
A_ When a power circuit is short-circuited, a large amount of current is transmitted into the fuse 2, so that the fuse 2 is molten. Therefore, the current of the power circuit is broken. Further, when the collision accident of the vehicle occurs, the acceleration sensor 6 outputs the electric signal by detecting the acceleration produced by the collision accident, and then the breaker 5 is provided with the electric signal in accordance with the acceleration. Therefore, the breaker 5 acts so as to break between the battery I and the control.apparatus 3. As a result, since the control apparatus 3 and the motor 4 are not provided with the current from the battery 1, the electrical vehicle is in a stop state.
Although the breaker equipped the acceleration sensor is employed as a switch device in the first embodiment, the other switch device equipped the sensor may be employed as far as which has a similar effect to the first embodiment.
Moreover, although the above embodiments are described with regard to the safety apparatus in the power circuit of the electric vehicle, the safety apparatus may be constructed in the other electric circuit of the electric vehicle. Besides the breaker as described in the embodiments of the present invention, the acceleration sensor may be connected to an antiskid braking system, an air bag system, a torque control system or the like.
As described above, according to the present invention, since the safety apparatus for the electric vehicle is provided b with the switch device breaking between the driving power source and the motor in accordance with theacceleration produced when the collision accident of the vehicle occurs, the safety apparatus can effectively preven-t- the vehicle from travelling continuously.
