Description

Open and closed strucure of tail gate [

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an open / close structure of a tailgate for a vehicle, and more particularly to an open / close structure of a tailgate for preventing a spindle drive from being exposed to the outside.

Generally, a tailgate or a trunk for loading a user or loading a cargo is generally formed on the rear surface of the automobile.

The conventional tailgate is formed in a plate shape so as to cover and cover the rear opening portion opened over the entire rear surface of the vehicle body. A hinge is fastened to the top of the tailgate so that the tailgate is rotated with respect to the vehicle body. Lifters are generally installed to assist the lifting and lowering operations.

1, according to the user's selective operation, the conventional tailgate contacts the rear opening of the vehicle body with the hinge mounted on the rear upper end of the vehicle body, or rotates to the upper portion of the vehicle body So as to open and close the opening portion of the rear surface of the vehicle body. In addition, the lifter 1 is formed over the center point of the inner side of the tail gate and the center point of the opening of the vehicle body, and a filler having an elastic force such as a fluid or gas is inserted into the lifter 1, The filler of the lifter 1 is expanded so as to press the tail gate to the upper or lower portion of the dead point to help the tail gate up and down when the pressure of the tail gate 1 deviates from the dead point where mutual cancellation occurs.

However, since it is configured to be freely pivoted by the axis of the hinge, the degree of opening and closing of the tail gate can not be adjusted at a desired position by the user.

Further, the lifter 1 is composed of a plurality of lifters, and when the tail gate is opened or closed, the lifter 1 is exposed to the outside. Such exposure may appear complicated in appearance or may be confined in space, or may cause gas or malfunction in the lifter 1 when it is mistakenly or incorrectly lifted.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a tailgate for a vehicle that can be easily opened even when the rear space of the vehicle is narrow, and is excellent in openness and can be opened even with a small force.

In order to achieve the above object, the present invention provides a tailgate for opening and closing the rear of a vehicle body, comprising: a main hinge mounted on one side of the tailgate and fixed to the vehicle body such that the tailgate rotates in a vertical direction; A hinge shaft formed at a position corresponding to the main hinge, and a fixing pin mounted on the main hinge; A fixing bracket fixedly coupled to the hinge bracket; A rotation bracket rotatably mounted on the stationary bracket; A rotary link connected to a fixing pin mounted on the main hinge at one end thereof at a position spaced apart from the hinge axis and connected to one end of the rotation bracket at the other end; And a telescopic device connected to the other end of the rotation bracket to extend the length thereof to rotate the rotation bracket; And a rotational force for opening the tail gate in the hinge axis is generated by a force of the rotary link pressing the fixed pin according to the elongation of the stretching device.

The stretching device may be a spindle drive in which the motor rotates and expands the spindle by stretching the length.

The rotation bracket and the rotation link may be disposed one on each side of the expansion device.

The stretching device may be located at the upper end of the rear window of the tailgate.

According to the opening / closing structure of the tailgate of the present invention as described above, since the tailgate is not exposed, the trunk, that is, the rear space, can be sufficiently secured and not only the convenience of the occupant or the driver can be provided, Effect.

Further, even if the rear space of the vehicle is narrow, the tail gate is not exposed, and the effect of improving the appearance when viewed from the outside is obtained.

Fig. 3 is a view showing a state in which the tail gate is closed in the open / close structure of the tail gate shown in Fig. 1. Fig. 4 is a view showing a state in which the tail gate is opened in the open / close structure of the tail gate shown in Fig. FIG. 6 is a view showing the force from the expanding device and the force received by the rotating link in the opening / closing structure of the tail gate shown in FIG. 1 FIG. 7 is a diagram showing a comparison of space utilization of the conventional tail gate shown in FIG. 1 and the tail gate of the present invention.

2 to 7, the tail gate opening / closing structure according to the embodiment of the present invention relates to a tail gate 11 that opens and closes the rear side of the vehicle body 10. The open / close structure of the tail gate includes a hinge bracket 100, a fixed bracket 200, a rotating bracket 300, a rotating link 400, and a stretching device 500.

The hinge bracket 100 is mounted on one side of the tail gate 11. And a main hinge 110 fixed to the vehicle body 10 such that the tail gate 11 is vertically rotated. The hinge bracket 100 has a hinge shaft 120 formed at a position corresponding to the main hinge 110. The hinge bracket 100 includes a fixing pin 130 mounted on the main hinge 110.

The fixing bracket 200 is fixedly coupled to the hinge bracket 100. The rotation bracket 300 is rotatably mounted on the fixing bracket 200. Here, the fixing bracket 200 and the hinge bracket 100 are coupled to each other by a ball joint or a rotatable joint, so that the fixing bracket 200 and the hinge bracket 100 can rotate.

The rotation link 400 is connected to a fixing pin 130 mounted on the main hinge 110 at a position where one end is spaced apart from the hinge shaft 120. The other end of the rotation link 400 is connected to one end of the rotation bracket 300.

The extension device 500 is connected to the other end of the rotation bracket 300 so that the rotation device 300 is extended and rotated. Also, the expansion device 500 may be a spindle drive 500 that causes the motor to rotate the spindle to expand and contract in length. The stretching device 500 may be a lifter 500. Here, the spindle drive 500 and the lifter control the opening / closing of the hood or the trunk lid of the vehicle body 10, and the open state can be maintained when the spindle drive 500 and the lifter are opened. The telescopic device 500 may be mounted on the upper end of the rear window of the tail gate 11. As a result, the tail gate 11 may not be exposed outside the vehicle.

A rotational force is generated to open the tail gate 11 from the hinge shaft 120 by the force of the rotary link 400 pressing the fixing pin 130 according to the extension of the expansion device 500 . The rotation bracket 300 and the rotation link 400 may be disposed on each side of the extensible device 500, respectively. Here, the expansion device 500 is referred to as a spindle drive 500. The spindle drive 500 of the present invention can open and close the tail gate 11 with only one spindle drive. However, in the prior art, two are provided on each side. Therefore, it is not necessary to mount a plurality of the spindle drives 500, so that the cost of the spindle drive 500 can be reduced.

According to the opening / closing structure of the tailgate according to the present invention, as shown in FIG. 7, since the tailgate 11 is not exposed, the trunk, that is, the rear space can be sufficiently secured, But also has an effect of increasing the space.

In addition, even when the rear space of the vehicle is narrow, the tail gate 11 is not exposed, so that it has an effect of improving the appearance when viewed from the outside.

In addition, since the expandable apparatus 500 can be used only in one unit, the cost can be reduced.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
