The present invention relates to an auxiliary parking brake device, and more particularly, when the vehicle is parked, especially when parking in a place having a steep inclination, the auxiliary parking brake that secures the parking bracket installed on the vehicle body panel on the ground to maximize the brake effect. Relates to a device.

In general, automobiles are provided with parking brakes called foot brakes and hand brakes.

Parking brakes are used to prevent the movement of the car during parking or prolonged parking. Parking brakes like this one must have a very strong braking force. Because the driver must leave the car after parking, it is impossible to artificially give the car a braking force. In particular, when the car is parked in an inclined area that is not flat, a stronger braking force is required for the above reasons.

Accordingly, drivers who do not trust the braking force of the parking brakes have buried brakes such as stones or wood on their wheels to prevent the car from moving. However, it was very inconvenient as well as fluid, making it difficult to expect the full braking power of the car.

In addition, the vehicle has been parked in an inclined position, the parking brake is applied, and the gear is operated in the opposite direction to the downward inclination direction to prepare for a situation in which the car slips.

However, in this case, the driver may start the vehicle in a geared state, and when the clutch is applied, the vehicle may be greatly shaken and the starting may be stopped. This can put a strain on the car and shorten the life of the car.

Therefore, those skilled in the art have been looking for a separate device for assisting the parking brake.

It is therefore an object of the present invention to provide an auxiliary parking brake device in which an existing parking brake is additionally installed on the lower body panel of the vehicle and fixed directly to the ground.

In order to achieve the above object, the present invention provides a piston having a piston rod and two cylinders each including a first space and a second space at left and right sides of the piston and mounted to the lower body panel of the vehicle; Two parking brackets fixed to an upper portion of the piston rod of the cylinder, and fixed to a lower surface of the cylinder rod, and rotatably mounted to the lower body panel; An actuator having a first supply line and a second supply line connected to the first space and the second space of the cylinder, respectively, and having an intake manifold connected thereto; It is characterized by consisting of a control switch connected to the actuator.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows the installation state of the brake device according to the present invention, the detailed rear light substructure of the vehicle is omitted for clarity.

According to FIG. 1, two cylinders 10 are mounted on the lower body panel P of the vehicle in the center, ie between two rear wheels W. In addition, two parking brackets 20 are rotatably mounted to the panel P. FIG. The cylinder 10 has a piston rod 11 and the cylinder 10 is connected to an intake manifold via an actuator described in detail below to receive air.

In more detail with respect to the parking bracket 20, the upper portion of the bracket 20 is rotatably fixed by a hinge 22 provided in the fixture 21 mounted to the lower portion of the vehicle body. The lower portion of the bracket 20 is integrally formed or attached to a fixture 23 of a predetermined size so as to be firmly fixed to the ground. In addition, the piston rod 11 of the cylinder 10 is connected to the upper position of the support bracket 20 by a hinge pin 12. Accordingly, in the normal state, the piston rod 11 is in a protruding state, and the bracket 20 is also maintained in the shifted toward the vehicle lower body panel P.

The configuration diagram showing the operation adjustment state of the cylinder according to the invention in detail is shown in detail in FIG.

According to FIG. 2, the cylinder 10 has a piston 13 therein. First and second spaces S1 and S2 are formed at the left and right sides of the phone 13.

At both sides of the cylinder 10, that is, the first space S1 and the second space S2, each air supply line, that is, the first supply line 31 and the second supply line 32, may be provided with an actuator ( 30). The actuator is also connected to the intake manifold 10 to receive air. In addition, a switch 50 provided in front of the driver's seat is connected to the actuator 30 by a wire to operate the actuator 30 with the switch 50. That is, as the switch 50 is operated, the actuator 30 supplies air through the first supply line 31 and / or the second supply line 32.

In the operation of the auxiliary brake device of the present invention according to such a structure and connection state, when the driver operates the parking brake and presses the switch 50, the actuator 30 is operated to operate the first space S1 of the cylinder 10. At the same time as supplying air to the air discharge of the second supply line (S2). The piston rod 11 is reversed together with the piston 13 so that the parking bracket 20 is rotated downward so that the fixture 23 is fixed to the ground to perform an auxiliary parking brake function. At this time, since the second space P2 and the second supply line 32 maintain a vacuum, the piston is not pushed toward the first space S1. Thereafter, to release the auxiliary parking brake, pressing the operation switch again causes the actuator 30 to supply air to the second space S2 of the cylinder 10 through the second supply line 32 and at the same time the first space ( Drain the air of S1).

After the piston 13 is advanced to rotate the bracket 10 upwards to return to the original position to release the parking brake.

As a result, according to the auxiliary parking brake according to the present invention, the auxiliary parking brake can be easily operated by a switch operation, and in particular, an excellent braking force can be secured on an inclined surface.

While preferred embodiments of the present invention have been described above, it will be understood by those skilled in the art that various modifications and changes can be made without departing from the scope of the appended claims.
