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

Figure 2 is an exploded perspective view showing a pedal of the pedal-type parking brake device according to the present invention, Figure 3 is a diagram showing the state of use of the pedal of the pedal-type parking brake device according to the present invention.

2 and 3, the pedal of the pedal-type parking brake apparatus according to the present invention is composed of a pedal body 20, the pad 30, the footrest 40 and the elastic member 50.

In more detail, the main body 20 has a fixing hole 21 formed in the upper portion so as to be rotatably mounted to the bracket 2 by the shaft 4 as described above, and can transmit the driver's pressing force to the brake device. So that it is formed into irregular curved shapes.

The pad 30 is integrally formed at the lower end of the main body 20, and a rectangular accommodating portion 31 is formed at the upper surface of the pad 30.

An upper portion of the accommodating portion 31 is closed, and an opening 31a is formed under the accommodating portion 31, and a guide groove 32 is formed in the center of the accommodating portion 31 in the longitudinal direction.

In addition, the support pieces 33 and 34 protrude from the opening 31a of the accommodation portion 31, that is, the lower center portions of both sides of the guide groove 32.

Meanwhile, support grooves 35a and 36a are formed at both side portions 35 and 36 of the accommodation part 31.

The footrest 40 is inserted into the pad 30 so as to be movable, and the guide rail is inserted into the guide groove 32 formed in the center of the pad 30 at the center of the rear surface 41 of the footrest 40. 42 is formed to protrude.

In addition, each of the support pieces 33 and 34 of the pad 30 may be inserted into the rear surface 41 of the scaffold 40, more specifically, both side portions of the guide rail 42 to be movable. Insertion grooves 43 and 44 are formed.

Meanwhile, both sides 45 and 46 of the scaffold 40 are inserted into the support grooves 35a and 36a respectively formed at both sides 35 and 36 of the receiving part 31 of the pad 30. The support rails 45a and 46a protrude.

Of course, the flat portion opposite the rear surface 41 of the footrest 40 is knurled to prevent the shoe sole from slipping when the driver steps on the footrest.

An elastic member 50 is inserted into each of the insertion grooves 43 and 44 of the scaffold 40, and the upper end 51 of each elastic member 50 is inserted into each of the scaffold 40. It is fixed to the upper end of the groove (43, 44), the lower end 52 is in contact with or fixed to each of the fixing piece (33, 34) of the pad (30).

According to the assembly method and the operation mode of each component of the pedal-type parking brake device according to the present invention, first, the operator can insert the footrest 40 to be moved to the pad 30 formed integrally with the pedal body 20. Let's do it.

At this time, the elastic member 50 is inserted into each of the insertion grooves 43 and 44 of the scaffold 40, and the upper end portion of the elastic member 50 is disposed above the respective insertion grooves 43 and 44. 51 is fixed and each lower end portion 52 of the elastic member 50 is fixed to or fixed to each of the fixing pieces 33 and 34 of the respective pads so as to remain in contact with the footrest 40. Ensure resilience is provided.

In addition, the support rails 45a and 46a respectively formed on both sides 45 and 46 of the footrest 40 are rotatably inserted into the respective support grooves 35a and 36a of the pad 30.

Of course, in the assembly state of the pad 30 and the footrest 40, the guide rail 42 of the footrest 40 is inserted into the guide groove 35 of the pad 30 so that the footrest 40 is flexible. It can be moved up and down stably.

In this assembling state, when the driver presses the parking brake pedal to park the car, it is moved downward from the pad 30 by the pressing force applied to the footrest 40 as shown by the dotted line in FIG. 3.

Thus, the area where the sole of the driver comes into contact with the brake pedal is approximately the area where the area of the footrest 40 is added to the area of the pad 30 so that the driver's pressing force can be precisely and strongly applied to the brake pedal. .

Then, when the driver releases the pedal in the state in which the parking brake is locked, the footrest 40 is moved upward by the restoring force of the elastic member 50 that elastically supports the footrest 40 and returns to its original position.

Of course, when the footrest 40 moves up and down, the guide rails 41 of the footrest 40 and the support rails 45a and 46a of both sides 45 and 46 and the guide grooves 31 of the pad 30 are of course. ) And the support grooves 35a and 36a of both sides 35 and 36 may be moved flexibly and stably.

In particular, the scaffold 40 is not only firmly maintained in the support grooves 35a and 36a of the pad 30 of the support rails 45a and 46a of the scaffold 40 but also the maximum downward movement of the scaffold 40. Since the elastic member 50 is limited to the height at the maximum compression, the footrest 40 can be firmly fixed to the pad 30 even when the footrest 40 is moved downward, so that the driver can accurately press the pedal. Can be applied.

As a result, if the pedal according to the present invention is applied to the pedal-type parking brake device, when the driver steps on the pedal, the footrest is elastically moved downward from the pad of the pedal, thereby increasing the contact area with the sole of the driver, thereby making parking easier and more robust. It is effective to operate the brake system.

Although a preferred embodiment according to the present invention has been described above, it will be understood by those skilled in the art that various modifications and variations can be made without departing from the scope of the appended claims.
