Description

Tailgate locking device {TAIL GATE LOCKING APPARATUS}

The present invention relates to a tailgate locking device, and more particularly, to a tailgate locking device capable of fixing a tailgate to a gate trim of a vehicle using a magnetic clamping unit and a latch unit.

In general, users of recreation vehicles (RVs), such as MPVs (Multi-Purpose Vehicles) and SUVs (Sports Utility Vehicles), tend to load more luggage into vehicles than users of general sedans.

In addition, as the income level and working conditions are improved due to the improvement of the working conditions due to the five-day workweek, the demand for recreational vehicles (RVs) is continuously increasing because the number of people who want to enjoy various leisure and hobbies is increasing.

A tailgate is configured in some vehicles such as recreational vehicles, light vehicles, and vans.

Such a tail gate is a kind of door installed at the rear of a vehicle to load cargo or people. That is, the tailgate is a means configured on the rear vehicle body, and is configured to be opened and closed vertically. In recent years, the tailgate is relatively large in size and has a large turning radius because a large open area is required to load more cargo.

The tailgate is provided with a door latch that restrains and releases the striker fixed to the vehicle body. These door latches are responsible for locking and opening the tailgate.

However, in the conventional case, when a user loads or unloads a load into or out of a vehicle, injuries such as head collision and pinching by a door latch occur frequently. Accordingly, in the conventional case, the safety of the user could not be ensured by the door latch of the tailgate.

Matters described in this background section are prepared to enhance understanding of the background of the invention, and may include matters that are not already known to those of ordinary skill in the art to which this technology belongs.

Referring to FIG. 4 , the magnetic clamping unit 200 according to an embodiment of the present invention includes a first magnet 210 and a second magnet 215 .

The first magnetic 210 is configured inside both sides of the gate trim 100 . The first magnetic 210 receives power from the power supply unit 350 under the control of the vehicle controller 330 .

That is, when the vehicle speed is equal to or greater than the reference speed, the first magnetic 210 receives power from the power supply unit 350 and has magnetism. In this case, the first magnetic 210 may have a different magnetism from the second magnetic 215 . For example, the first magnetic 210 may have S-pole magnetism when receiving power from the power supply unit 350 .

The first magnetic 210 may be an electromagnet having magnetism as a current flows through a power source. Since the first magnetic 210 may have strong magnetism through current, it may be more strongly coupled to the second magnetic 215 .

The second magnetic 215 is configured in the inner side of both sides of the tailgate 150 corresponding to the first magnetic 210 .

The second magnetic 215 may have a certain magnetism. That is, the second magnetic 215 is formed of a permanent magnet having a magnetism different from that of the first magnetic 210 . For example, the second magnetic 215 may have an N-pole magnetism.

Accordingly, in the tailgate locking device according to an embodiment of the present invention, the tailgate 150 can be fixed to the gate trim 100 through electromagnetic force using the first magnetic 210 and the second magnetic 215 . have.

5 is a perspective view illustrating a latch unit according to an embodiment of the present invention.

Referring to FIG. 5 , the latch unit 250 according to an embodiment of the present invention includes an actuator 265 , a latch member 270 , and a locking hole 160 .

The actuator 265 is configured inside the lower center of the gate trim 100 .

The actuator 265 receives power from the power source 350 . In this case, the actuator 265 receives the previous month from the power supply unit 350 when the vehicle speed is equal to or greater than the reference speed under the control of the vehicle controller 330 .

When power is supplied, the actuator 265 rotates the latch member 270 to project the latch member 270 into the locking hole 160 formed in the tail gate 150 and the opening 110 formed in the gate trim 100 . .

The latch member 270 is configured inside the lower center of the gate trim 100 and protrudes upward from the lower portion of the gate trim 100 depending on whether power is applied. The latch members 270 are configured on both inner sides of the lower center of the gate trim 100 and are rotationally operated by the actuators 265 in mutually opposite directions.

One end of the latch member 270 is fixed by being fitted on the rotation shaft of the actuator 265 , and the tip of the latch member 270 is bent. The latch member 270 includes a hinge part 273 , a rotation part 275 , and a locking end 277 .

The hinge part 273 is fitted and fixed to the rotation shaft of the actuator 265 inside the lower center of the gate trim 100 .

One end of the rotating unit 275 is hingedly connected to the hinge unit 273 , and is rotated from the hinge unit 273 depending on whether power is applied and protrudes upward. That is, the rotating part 275 may protrude into the opening 110 and the locking hole 160 while rotating from the hinge part 273 by the operation of the actuator 265 .

Since the locking end 277 is caught in the opening 110 of the gate trim 100 and the locking hole 160 of the tail gate 150 , the tail gate 150 may be fixed to the gate trim 100 .

The locking hole 160 is formed in the lower center of the tail gate 150 to correspond to the latch member 270 . In the locking hole 160 , the latch member 270 is hooked and fixed with respect to the gate trim 100 in a state in which the tail gate 150 is closed.

6 is a perspective view showing a state before the latch unit is operated according to an embodiment of the present invention.

Referring to FIG. 6 , the latch unit 250 is configured under the opening 110 of the gate trim 100 when the vehicle speed is less than the reference speed under the control of the vehicle controller 330 . That is, the rotating parts 275 of each of the latch members 270 formed on both sides may be disposed in parallel in the width direction of the vehicle body when power is not supplied from the power supply unit 350 .

Thereafter, when power is supplied from the power supply unit 350 , the rotation unit 275 and the locking end 277 of the latch member 270 rotate as shown in FIG. 6 , so that the opening 110 of the gate trim 100 and It is caught in the locking hole 160 of the tail gate 150 to fix the tail gate 150 to the gate trim 100 .

Accordingly, in the locking device of the tailgate according to an embodiment of the present invention, when the vehicle speed is less than the reference speed, the first magnetic 210 and the second magnetic 215 of the magnetic clamping unit 200 are not fastened, Since the locking end 277 of the latch unit 250 does not protrude into the opening 110 of the gate trim 100 and the locking hole 160 of the tail gate 150 , the user can easily gate trim the tail gate 150 . (100) can be separated.

In addition, in the locking device of the tailgate according to an embodiment of the present invention, power is applied to the first magnetic 210 when the vehicle speed is greater than or equal to the reference speed, so that the first magnetic 210 and the second magnetic 215 are generated by electromagnetic force It is fixed, and power is applied to the actuator so that the locking end 277 of the latch member 270 protrudes into the opening 110 of the gate trim 100 and the locking hole 160 of the tail gate 150, so that the gate trim 100 ) may be fixed to the tailgate 150 .

Although the above has been described with reference to a preferred embodiment of the present invention, those of ordinary skill in the art can variously change the present invention within the scope without departing from the spirit and scope of the present invention described in the claims below.
