Description

Parking Cable Joint Structure for Electric Parking Brake

The present invention relates to a parking cable connection structure of an electric parking brake, and more particularly, in an electric parking brake configured to release or release a parking state of a vehicle by pulling or releasing the parking cable with a rotational force of a motor. This is a technology related to the connection structure between the parking actuator and the parking cable.

The electric parking brake device provides a convenient function to automatically set or release the parking state of the vehicle with a simple switch operation. The electric parking brake is provided with a parking actuator for pulling or releasing the parking cable according to a switch operation. When the parking actuator pulls the parking cable, a parking state of the vehicle is formed, and when the parking cable is released, the parking state is released. It has a mechanism

1 illustrates a configuration in which a parking cable is connected to a conventional parking actuator, and a yoke 502 provided at an end of the parking cable 500 penetrates them in a state coupled to the slider 506 of the parking actuator 504. The configuration is connected to each other by a fastening bolt 508.

However, in the structure in which the yoke 502 on the parking cable 500 side and the slider 506 on the parking actuator 504 are coupled to each other by the fastening bolt 508, the fastening bolt 508 is fastened. To the yoke 502 or the slider 506 is required to process the screw, there is a fear that the fastening bolt 508 is released as the repetitive operation of the parking actuator 504 accumulates.

Conventionally, in order to prevent the fastening of the fastening bolt 508 as described above, it is possible to apply Loctite to the fastening portion, or to interpose the spring washer in the coupling portion.

Therefore, in the structure as described above, the assembling process is slightly longer and slower to assemble the fastening bolt 508 and assemble the fastening bolt 508 in the state of applying Loctite or interposing a spring washer.

In addition, it is difficult to secure work efficiency without using equipment such as a power tool for fastening the fastening bolt 508 to connect the parking cable 500 and the parking actuator 504, such as the power tool If not necessarily to assemble or remove the fastening bolt 508 requires a tool such as a screwdriver.

In addition, as described above, the screw coupling portion of the fastening bolt 508 may be damaged due to the repeated operation of the parking actuator 504. If such a phenomenon occurs, the screwing portion may not be easily removed. There is a problem that its poor maintenance.

The present invention has been made to solve the problems as described above, the assembly of the parking cable and the parking actuator can be made easily and quickly, without using a special tool, as well as ensuring the stability of the connection state It is an object of the present invention to provide a parking cable connection structure of an electric parking brake that can provide easy maintenance that can be easily detached or combined at any time even in repeated operation.

The parking cable connection structure of the electric parking brake of the present invention for achieving the above object is

A cable side coupling member which forms a cable coupling hole formed in a direction perpendicular to the longitudinal direction of the parking cable and is integrally coupled to an end of the parking cable;

An actuator side coupling member having an actuator coupling hole communicating with the cable coupling hole at a portion overlapping with the cable side coupling member;

A coupling pin that penetrates the cable coupling hole and the actuator coupling hole disposed so as to be in communication with each other;

The clip is integrally provided with the coupling pin to switch between the state in which the coupling pin is stably inserted into the cable coupling hole and the actuator coupling hole and the state in which the coupling pin is released by the elastic deformation thereof. ;

And a control unit.

According to the present invention, the assembly of the parking cable and the parking actuator can be made easily and quickly without using a special tool, and the stability of the connection can be ensured, and it can be easily detached or combined at any time even in a repeated operation. To provide easy maintenance.

3 is a view of the assembly of the structure of FIG.
4 is a view showing a state in which the clip and the coupling pin is coupled to the yoke, omitting the rod in the structure of FIG.
FIG. 5 is a view illustrating the clip and the coupling pin of FIG. 2 separately. FIG.

2 to 5, the embodiment of the present invention forms a cable coupling hole 3 formed in a direction perpendicular to the longitudinal direction of the parking cable 1 and is integrally coupled to the end of the parking cable 1. Side coupling members; An actuator side coupling member having an actuator coupling hole 5 communicating with the cable coupling hole 3 at a portion overlapping with the cable side coupling member; A coupling pin (7) passing through the cable coupling hole (3) and the actuator coupling hole (5) at a time so as to overlap with each other; The coupling pin 7 is provided integrally with the coupling pin 7 to stably fix the state inserted into the cable coupling hole 3 and the actuator coupling hole 5 and to release the fixing state. And a clip 9 adapted to switch between them by their elastic deformation.

One of the cable side coupling member and the actuator side coupling member is composed of a yoke 11 having a central portion and an open side, and a rod 13 inserted into the central portion of the yoke 11.

In the present embodiment, the cable side coupling member is made of a yoke 11, and the actuator side coupling member is made of a rod 13 formed integrally with the slider 21, but the reverse configuration may of course be possible.

The clip 9 is coupled to the coupling portion 15, one end of the coupling pin 7 is inserted and coupled, and bent while extending to both sides from the coupling portion 15 to elastically both sides of the yoke 11 It is configured to include a catching portion 17 formed to be wrapped around the side of the yoke (11).

The coupling pin 7 is coupled to the coupling portion 15 of the clip 9 by caulking, the locking portion 17 of the clip 9 is the central portion of the yoke 11 into which the rod 13 is inserted. It is elastically inserted at both sides of the furnace, the coupling pin 7 has a structure having a locking jaw 19 to form a fixed state to limit the movement in the opposite direction inserted into the yoke (11).

Of course, in addition to the locking portion 17 of the clip 9 may be of a structure surrounding the whole of the yoke (11).

The parking cable 1 connection structure of the electric parking brake configured as described above inserts the yoke 11 on the parking cable 1 side and the rod 13 provided on the slider 21 of the parking actuator to each other. The clip 9 at the end of the process of inserting the coupling pin 7 and inserting the coupling pin 7 with the cable coupling hole 3 and the actuator coupling hole 5 arranged to coincide with each other. The clip 9 is elastically coupled to the yoke 11 by pressing the fastening portion of the clip 9 so that the locking portion 17 of the locking portion 17 is fastened to the yoke 11.

While inserting the coupling pin 7 as described above, pressing the clip 9 until the clip 9 is fastened, such that the state in which the coupling state of the coupling pin 7 remains stable is secured. do.

Therefore, the connection work of the parking cable 1 and the parking actuator is made very simple and easy, and does not require any additional equipment.

Of course, the coupling pin 7 is not formed with the same thread as the conventional fastening bolt, so there is no risk of damage to the thread even if the repetitive operation of the parking actuator is accumulated. Only by opening the separation of the coupling pin (7) is made easily, so that the maintenance is also very effective.
