FIG. 1 is a perspective view showing an embodiment of a detachable vehicle trunk automatic opening and closing apparatus according to the present invention, and FIG. 2 is a sectional view showing an embodiment of a detachable automatic trunk opening and closing apparatus of the present invention.

1 and 2, the present invention may include a shaft 110, a driving cylinder 120, a housing, and a driving unit.

The shaft 110 is provided with a multi-threaded screw, for example, a two-row screw, and is fixed to the inner surface of the trunk hood 10 by being hinged to the suction plate 160 at one end. Since the suction plate 160 is made of rubber or silicone and is attracted to and fixed to the inner surface of the trunk hood 10 and the shaft 110 is hinged to the hood, the trunk hood 10 is opened, The engagement state of the attraction plate 160 and the shaft 110 can be maintained.

Multi-threaded screws are used as feed slip screws when the lead, that is, when the screw is turned one turn, is twice as long as the nut moves, compared to a single-threaded screw. According to the present invention, by applying a multi-threaded screw so that the trunk hood 10 can be opened and closed quickly, it is possible to operate smoothly by a simpler structure than a conventional operating mechanism by a hydraulic mechanism.

The driving cylinder 120 is a hollow cylinder into which the shaft 110 enters and leaves and is provided with a rotating body in which a multi-threaded screw is formed so as to engage with the thread of the shaft 110 on the inside diameter portion. One end of the driving cylinder 120 is provided with a gear to receive the driving force of the driving units 130 and 140. The shaft 110 is fixed to the trunk hood 10 by the attracting plate 160 and the driving cylinder 120 is rotated by the driving unit so that the shaft 110 moves in the driving cylinder 120 .

At this time, the upper and lower ends of the drive cylinder 120 may be coupled with the bearings b so as to be rotatable within the housings 150 and 170.

The housing may include a cylinder housing 150 to which the driving cylinder 120 is fixed and a driving housing 170 which is connected to the cylinder housing 150 and includes the reducer 130 and the motor 140.

3, the bracket 280 is formed of a hinge member connecting between the driving unit housing 270 and the bottom surface of the trunk (t), so that the entire opening and closing device can be rotated according to the opening angle of the trunk hood 10 .

 The driving unit may include a speed reducer 130 and a motor 140. Also, although not shown in the figure, the driving unit may further include a control unit which can be operated by the remote controller. The control unit causes the trunk hood 10 to be opened by activating the motor 140 when the trunk hood 10 is released according to the signal of the remote controller so that the trunk hood 10 is opened when the remote control signal is transmitted once again. 140 to operate in the reverse direction so that the trunk hood 10 is closed. Accordingly, since the trunk hood 10 can be opened and closed by using a remote controller for a vehicle that has been used after the opening and closing apparatus 100 is installed, an additional control mechanism is unnecessary.

The speed reducer 130 is configured to transmit power to the driving cylinder portion 120. The speed reducer 130 and the driving cylinder portion 120 may be coupled with a bevel gear or a spur gear. Since the trunk hood 10 is normally held open by the hydraulic cylinder when the trunk hood 10 is opened over a predetermined angle, it is possible to open or close the trunk hood 10 without considering the backlash of the gear connecting the speed reducer 130 and the driving cylinder 120 Smooth function can be realized by a simple operation of accelerating the trunk hood 10 at the beginning of closing.

The operation of the detachable automatic trunk opening / closing apparatus according to the present invention will now be described.

According to the present invention, a trunk can be conveniently opened and closed by providing an opening / closing device that can be easily installed using a suction plate inside a trunk of an existing vehicle without a trunk hood driving device. It is possible to install without changing the internal structure of the existing trunk.
