Description

Tail Gate Popup Function Replacement Device {Device having pop up function of Tail gate}

The present invention relates to a tail gate popup function replacement device for restraining the lock rod from being restored by a return spring mounted inside the tail gate latch assembly when the tail gate of the hatchback type vehicle is opened. When opened at an angle less than or equal to an angle, the lock rod cannot be restored to its pre-release state by a return spring mounted inside the tail gate latch assembly to prevent the tail gate latch assembly from performing a locking function, and the tail gate is horizontal. In the case of opening at the above angle, the lock rod can be restored to the state before release, and the tail gate pop-up function replacement device having a locking function when the original function is closed.

In general, a tail gate is formed at the rear of a hatchback type vehicle so as to be opened and closed in a vertical direction using a gas lift, and a tail gate release lever is provided at one side of a driver's seat in the cabin to open the tail gate. have.

FIG. 1 is a view illustrating a tail gate of a general hatchback type vehicle, and FIG. 2 is a view illustrating a tail gate latch assembly mounted on a portion A of FIG. 1, and FIG. 3 is a tail gate mounted on a portion B of FIG. 1. It is a figure which shows a striker.

As shown in the figure, the tail gate 2 is hingedly coupled to the gas lifter 3 on the upper end of the vehicle body 1 so as to be rotatable in the up and down directions, and at the center of the lower end of the tail gate 2. A tail gate latch assembly 4 is installed to maintain the closed state stably while driving and to be opened by a driver's operation as necessary, and the tail gate latch assembly 4 is fixed to the vehicle body 1 side. It is fastened to the striker 5 and is formed to maintain the locked state of the tail gate (2).

Meanwhile, the tail gate latch assembly 4 is connected with a release lever and a cable so as to be opened and closed in a vehicle interior, and a weather strip for performing a watertight action on the contact portion between the tail gate 2 and the vehicle body 1. 6) is installed.

As shown in FIG. 2, when the driver operates the tail gate release lever installed at one side of the driver's seat in the vehicle interior, the tail gate latch assembly 4 is connected to the actuator 8 through the cable 7. Is transmitted, the motor and the gear mounted inside the actuator (8) is operated by the electric signal to rotate the rotating piece (9), the locking rod 10 hinged to the rotating piece (9) left and right It is reciprocated to unlock the latch 11 engaged with the door striker 5.

As shown in FIG. 3, the door striker 5 has two pop-up springs 12 mounted to the front side with respect to the center axis, and the latch 11 of the tail gate latch assembly 4 on the center axis. Is coupled to the hook portion 13 is formed to perform the locking function of the tail gate (2).

The function of the pop-up spring 12 is that when the driver operates the tail gate release lever in the driver's seat or releases the engagement of the tail gate latch assembly 4 and the door striker 5 by using a key, the tail gate 2 It is to keep open so as not to be locked by self weight.

The tailgate pop-up structure of the conventional hatchback type vehicle having the above configuration is a design factor that further requires the repulsive force of the pop-up spring because the tail gate is installed in a form in which the tail gate is laid horizontally close to the exterior styling, and in particular, the tail gate latch assembly After opening the tail gate from the driver's seat, opening and lowering the driver's door to move toward the tail gate, and then closing the driver's door, the tail gate suddenly increases and the pop-up spring's repulsive force is not enough. If not, there is a problem that the tail gate is locked due to the hilarious force and the weight of the tail gate.

An object of the present invention devised to solve the above problems is that when the tail gate of the hatchback type vehicle is opened, the tail gate is restrained from being restored by the return spring mounted inside the tail gate latch assembly. It is trying to solve the problem of being locked out.

In order to achieve the object of the present invention as described above, when the tail gate is opened at an angle of less than or equal to horizontal, the tail is restrained from being restored to the state before release by the return spring mounted inside the tail gate latch assembly. If the gate latch assembly is not locked and the tail gate is opened at an angle above horizontal, releasing the rod restraining device restores the lock rod to the state before release, so that the tail gate latch assembly has a locking function when the gate latch assembly is closed as it is. It provides a tail gate pop-up function replacement device.

Hereinafter, a tail gate popup function replacement apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

4 is a view illustrating a tail gate latch assembly equipped with a tail gate popup function replacement device according to an exemplary embodiment of the present invention, and FIG. 5A illustrates a popup function when a lock rod of a tail gate is constrained. FIG. 5B is a diagram showing the operation of the substitute device when the lock rod of the tail gate is released.

As shown in the figure, on the rear surface of the tail gate latch assembly 100, the lock rod 110 is restored by a return spring mounted inside the tail gate latch assembly 100 when the tail gate is opened at an angle of less than horizontal. The rod restraint device 200 for restraining it from being attached is attached using the fixing bracket 300.

The rod restraint device 200 can be reciprocated by using the housing 210 formed in a cylindrical shape and the elastic force of the elastic member 224 and the load of the metal ball 230 on the central axis of the housing 210. Constrained member 220 and the iron ball 230 for pressing the restraining member 220 by its own weight by the opening angle of the tail gate.

In the middle of the lock rod 110, a fixing piece 112 engaging with the restraining member 220 of the rod restraint device 200 is protruded.

The restraining member 220 is formed in a 'TT' shape, the upper side is formed with a pressing plate 226 pressed by the weight of the iron ball 230, the lower side of the pressing plate 226 of the lock rod 110 A locking portion 222 contacting the fixing piece 112 is formed in a vertical direction, and an elastic member 224 having elastic force is mounted on an outer circumferential portion of the locking portion 222.

Referring to the operation of the tail gate pop-up function replacement device according to an embodiment of the present invention having the configuration as described above, when the tail gate is also lower than the horizontal angle as shown in Figure 5a, the iron ball 230 Since the fastening member 112 of the lock rod 110 is caught by the locking portion 222 of the restraining member 220 because the restraint member 220 is pressed by itself, the return operation of the lock rod 110 is constrained.

On the contrary, when the tail gate was opened at an angle equal to or greater than horizontal, as shown in FIG. 5B, since the iron ball 230 moved away from the restraining member 220 to the end of the housing 210, the restraining member 220 was pressed. When the force is removed, the restraining member 220 is moved using the elastic force of the elastic member 224, and at this time, the locking state of the locking portion 222 and the fixing piece 112 of the restraining member 220 is released. As a result, the restrained state of the lock rod 110 is released.

The present invention having the configuration as described above can replace the existing pop-up spring can improve the assembly and maintainability, can remove the operation sound caused by the operation of the spring, due to the deterioration of the spring The problem can be fundamentally solved and mounted on an invisible part inside the trim, which has the effect of improving the appearance of the body.
