The vehicle brake stabilizer according to the present invention is installed in a vehicle 1 such as a small car, a medium car, and a large car, and when the side brake is not locked on a slope, the vehicle 1 is rolled up arbitrarily to promptly recognize the driver and a large accident occurs. It is a product to prevent it.

To this end, the vehicle brake stabilizer according to the present invention may include a first detection unit 10, a second detection unit 20, an alarm unit 30, and a control unit 60.

The first detecting unit 10 detects whether the driver's seat 2 of the vehicle 1 is opened or closed.

 In a first embodiment, the first sensing unit 10 may be formed of a photosensor including a light emitting unit and a light receiving unit which are installed in the groove 2c in which the open lever 2a is installed among the inner surfaces of the driver's seat. Can be.

The photosensor may be activated when the vehicle is started, and the light emitter may emit light, and the light receiver may receive light emitted from the emitter.

In the present invention, when the driver changes the side brake to the lock mode, the power applied to the first sensing unit 10 is cut off, and when the driver touches the open lever 2a without changing the side brake to the lock mode. A part of the finger enters the groove to cover the light of the light emitting unit, and thus, the light receiving unit cannot receive the light and generates an error signal to transmit to the electrically connected control unit.

In a second embodiment, the first detecting unit 10 may be set to detect whether the driver's door 2 is open.

In addition, when the driver opens the driver's door 2 by operating the open lever 2a, the first detection unit 10 transmits the control to the electrically connected controller 60.

Since the first detecting unit 10 of the second embodiment is the same as the sensor displayed on the instrument panel in the vehicle when the vehicle door is not completely closed in the general vehicle, a detailed description thereof will be omitted.

The second detecting unit 20 is for detecting the lock mode and the release mode of the side brake 3 installed inside the vehicle 1, which may also be formed as a sensor.

The second detecting unit 20 detects the lock mode and the release mode of the side brake 3 in real time and transmits it to the control unit 60, thereby preventing the driver from getting off without locking the side brake 3. have.

The alarm unit 30 may be electrically connected to the control unit 60, and may be formed as a buzzer operated by the control unit 60.

In this case, the alarm unit 30 may be installed at various positions such as an interior ceiling, a floor, and a dashboard of the vehicle 1.

The control unit 60 is installed inside the vehicle 1 and is electrically connected to the first detection unit 10, the second detection unit 20, and the alarm unit 30.

The control unit 60 detects the operation of the open lever 2a or detects an open state of the driver's seat 2, and when the second detecting unit 20 detects the release mode of the side brake 3, By operating the alarm unit 30 to generate an alarm sound, the driver recognizes that the side brake 3 is released, and induces the side brake 3 to switch to the lock mode and get off.

That is, the vehicle brake safety device according to the present invention can operate the open lever 2a or open the driver's door 2 so that the driver blinks after parking on the slope and gets off without converting the side brake 3 into the lock mode. When the first sensing unit 10, the second sensing unit 20 and the control unit 60 interacts with each other, the alarm unit 30 is operated to alert the driver acoustically and instill an alert, so that the side must be The brake 3 can be switched to the lock mode, which prevents the vehicle 1 from rolling down the slope and prevents a large accident from occurring.

In addition, the control unit 60 detects the operation of the open lever 2a and the release mode of the side brake 3 by the first detecting unit 10 and the second detecting unit 20, respectively, or the driver's door ( 2) When detecting the opening of the side brake (3) and the release mode of the side brake (3) generally lights up or flashes the door light (2b) installed on the inside of the driver's door (2) to visually inform the driver, the side brake (3) ) Can more clearly recognize that the brake is in the unlocked mode, and can effectively inform the driver that the side brake 3 is in the unlocked mode even for a driver who has a poor hearing function.

Of course, when the driver converts the side brake 3 to the lock mode, the second detection unit 20 transmits it to the control unit 60, and the control unit 60 stops the operation of the alarm unit 30. In addition, the alarm sound is not generated, and the door lamp 2b is turned off.

In addition, in the brake safety device according to the present invention, the first sensing unit 10 and the second sensing unit 20 respectively detect the operation of the open lever 2a and loosening of the side brake 3, or Upon detecting the opening of the driver's seat 2 and the release mode of the side brake 3, the driver may further include a blocking unit 80 blocking the exit of the driver's seat.

That is, when the driver tries to get off despite the alarm unit 30 and the door light 2b being operated, the blocking unit 80 prevents the driver from changing the side brake 3 to the lock mode and then gets off. It performs the function.

The blocking unit 80 may include a motor 81 and a blocking bar 82.

The motor 81 may be a DC motor 81 or an AC motor 81 in which a motor shaft rotates in a forward or reverse direction.

The motor 81 is electrically connected to the control unit 60, the operation is controlled by the control unit 60.

The motor 81 may be installed on the inner bottom surface or the ceiling surface of the vehicle 1, and in the drawing, the motor 81 is illustrated on the door side of the bottom surface of the vehicle 1.

The blocking bar 82 is formed to have a predetermined length and has a circular or square cross section.

One side of the blocking bar 82 is fixed to the shaft of the motor 81 may be rotated in the up, down direction by the power of the motor (81).

The blocking bar 82 maintains a state of being seated on the bottom surface of the vehicle 1 as usual.

In addition, the control unit 60 detects the operation of the open lever 2a and the loose brake of the side brake 3 by the first detecting unit 10 and the second detecting unit 20, or the driver's door ( When detecting the opening of 2) and the release mode of the side brake 3, the driver rotates the blocking bar 82 upward through the motor 81 to block the exit area of the driver's seat. Interfere not to get off.

In addition, when the driver converts the side brake 3 into the lock mode, the second sensing unit 20 transmits it to the control unit 60, and the control unit 60 operates the motor 81 to shut off. The bar 82 rotates back to its original position so that the driver can easily get off.

In this case, the motor 81 may be set to rotate the blocking bar 82 in an upward direction of about 30 degrees to about 90 degrees, that is, at an angle that is difficult for the driver to get off.

The blocking unit 80 may be applied to two or more, and in this case, the blocking bar 82 may be installed to block the exit of the driver's seat in a crisscross or X-shape.
