As such, the release switch 40 at the front and rear of the vehicle is released when the release switch 40 is pulled in the required position by being connected in parallel with the temporary release actuator 30, respectively.

In addition, although a spiral time delay gear 46 is formed on the sliding member 42 and the base 41 of the release switch 40, as shown in FIG. 3, the sliding member 42 and the switch knob ( 43 is a structure that is separated by the tension pulled when pulling the switch knob 43, the switch knob 43 is constrained to the hand to move forward along the helical structure even when linear movement.

Referring to the operation of the vehicle parking release device according to the present invention having the configuration as described above are as follows.

In densely populated areas such as apartments, double parking is common to make the best use of tight parking spaces. These double parked vehicles must be parked with the parking released to facilitate the movement of the vehicle inside.

Cars parked in this unparked state are pushed back and forth when the parking lot is not flat, causing contact accidents with other vehicles, causing damage to the vehicle.

With this problem in mind, the vehicle parking releasing device according to the present invention, even when the parking lever 10 is pulled and in the parking state, pulls the release switch 40 separately installed before and after the vehicle to facilitate the movement of the vehicle.

In addition, the vehicle parking releasing device according to the present invention can move the vehicle only after the release switch 40 is pulled out until the tension of the switch position recovery spring 45 returns to the position before the operation.

This is explained in more detail.

Referring again to the drawings, the vehicle parking releasing device according to the present invention, first, the temporary release operating device 30 for temporarily releasing the locking of the parking lever 10, the drum brake 20 by the release switch 40 When the tensioning force of the parking cable 11b on the) side is lost, the vehicle is temporarily released and then returned to the position before the release switch 40 is operated by the elastic restoring force of the first spring 36 without any additional operation. To be maintained.

5A is a state in which the release switch 40 is operated, and circle 'B' shows a portion in which tension is generated by pulling the release switch 40, and circle 'C' in FIGS. 5A and 5B. Is a state in which the parking cables 11b and 11c are relaxed due to the loss of tension.

5B shows the state when returning to the position before the release switch 40 is operated, and circle 'D' shows the part of the parking cable 11b where the tension is restored when returning to the position before the release switch 40 is operated. It is shown.

In addition, the release switch 40 for releasing the locking of the parking lever 10 releases the tension of the parking cable connected to the parking brake device when one is installed at each front and rear of the vehicle 50 and pulled out. It delays returning to the position before switch operation for a certain time.

6a shows a state in which the front end portion of the sliding member 42 moves forward while rapidly rotating.

6B illustrates a state in which the unlocking state is maintained for a predetermined time because the front end of the sliding member 42 is slowly returned by the gear structure when the switch position recovery spring 45 is returned to the switch position recovery spring 45.

This is explained in more detail.

In addition, FIG. 7A illustrates a state in which the parking state is temporarily released. Even when the release switch 40 is pulled out, the parking lever 10 maintains the parking state. And when pulling the release switch 40, the gear 46 of the front end portion of the sliding member 42 is advanced while rotating quickly. In addition, when the parking cable 11b loses tension due to relaxation, the spring in the drum brake 20 also loses tension and releases the parking state.

In addition, FIG. 7B illustrates a state in which the parking state is restored again. Even when the release switch 40 is pulled out, the position of the parking lever 10 is maintained in the parking state. And when the return to the switch position restoring spring 45, because the front end portion of the sliding member 42 is rotated by the gear structure to return slowly, the unlocking state is maintained for a certain time. In addition, when the tension of the parking cable 11b is restored again, the spring in the drum brake 20 is also restored to maintain the parking state.

On the other hand, when the ratio of the tension between the first spring 36 of the temporary release operating device 30 and the switch position recovery spring 45 of the release switch 40 will be described, the direction of movement according to compression and restoration of the spring is the same. Therefore, the ratio of the tensions of these springs 36 and 45 may be the same.

However, it should be considered to be 1.5 to 2.0 rather than the tension of the spring in the drum brake 20. This is due to the restoring force of the spring in the drum brake 20 when the tension of the first spring 36 of the temporary release actuator 30 is lower than the tension of the spring in the drum brake 20. While the first spring 36 is compressed, the parking cable 11b connected to the drum brake 20 is relaxed to prevent the parking from being released.

And if there is a release switch 40 in the front, rear of the vehicle 50, after the front release, the front is relaxed again when the rear release, the adjustment of this is made as follows.

The front release switch 40 and the rear release switch 40 are connected in parallel with the temporary release actuator 30, respectively, so that the parking of the rear release switch 40 when the front release switch 40 is pulled out. The parking cable 11d, which is connected to the rear release switch 40 when the cable 11d is more relaxed than the previous state and the front release switch 40 returns to the position before operation, is also used. It will return to the relaxed state.

As described above, the vehicle parking release apparatus according to the present invention has the following effects.

Even if the parking lever is pulled and the parking state is pulled, pull the release switch installed before and after the vehicle, pull the release switch, and move the vehicle until it returns to the position before operation due to the tension of the switch position restoring spring. You can temporarily disable parking.

In this way, the parking of the vehicle can be temporarily released, so that the vehicle can be parked only in the parking state at all times, so that the vehicles parked in the unparked vehicle are pushed back and forth to prevent contact problems with other vehicles. Can be.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
