Description

Mobile communication terminal having semiautomatic carkit cover using cushion rubber

The present invention relates to a car case cover of a mobile communication terminal, and more particularly, to a mobile communication terminal in which the car case cover is opened and closed automatically by a folder opening and closing operation in a folder type mobile communication terminal.

In general, a carkit of a mobile communication terminal refers to an I / O connector that connects a terminal to an external device when charging in a vehicle, downloading software to the terminal, or uploading data such as an address book. Carpet cover (cover) is a cover that can open and close the connector in order to prevent foreign matter from entering the terminal or damage the connector through the connector of the I / O connector is usually made of a rubber material.

Figure 1 is a perspective view of a conventional carpet cover. In the case of a clamshell mobile communication terminal, a carcase cover 10 is inserted into a carpet connector formed at a lower end of a lower folder to protect an I / O connector. The carpet cover 10 may be provided so that one end 11 is fixed to the connector and the other end of the opposite end is opened and closed in the direction of the arrow, and the carpet cover 10 itself formed of rubber or the like is separated or fitted It may be provided to open and close.

By the way, the carpet cover 10 is very small in size, is formed of a rubber-like material is easily deformed, it is difficult to open and close with one hand. When separated from the connector may be lost, due to the nature of the material there is a problem that is easily discolored or damaged due to frequent contact with the skin.

The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a mobile communication terminal in which a carpet cover is opened and closed automatically by opening and closing a folder using a cushion rubber.

In order to achieve the object of the present invention, a mobile communication terminal having a semi-automatic carpet cover using a cushion rubber according to the present invention, the upper folder; A lower folder formed with a carpet connector at a lower end thereof; And a hinge structure for rotatably connecting the lower end of the upper folder and the upper end of the lower folder, wherein the folder is exposed to an upper surface of the lower folder and contacts the upper folder when the terminal is closed. A cushion rubber comprising a shaft extending downward from the head by a predetermined length; A cushion rubber groove formed on an upper surface of the lower folder and into which the head of the cushion rubber can be inserted by a predetermined depth; An elastic member which provides a restoring force upward when the cushion rubber is pressed downward by the upper folder; And a cart cover connected to the shaft part to open or close the cart connector according to the vertical movement of the cushion rubber.

The elastic member has one end supported on one side of the cushion rubber, the other side is suitable for the compression spring is supported on the case of the lower folder, and provides a restoring force to the collision of the upper folder and the lower folder when the terminal is closed. It can play a role in mitigating impact.

The cushion rubber, the cushion rubber groove, and the elastic member may be provided at the center of the lower end of the lower folder, respectively, but are provided symmetrically on both sides of the lower end for stable operation, and the carpet cover is cushioned on both sides of the lower folder. It is preferable that it is provided connected horizontally to the axial part of the rubber.

The shaft portion of the cushion rubber may have a length such that the carpet cover connected to the distal end of the cushion rubber is closed when the terminal is opened and moves downward with the cushion rubber when the terminal is closed to open the carpet connector. On the contrary, by forming the terminal shorter than the length by the predetermined length, when the terminal is opened, the cart connector may be opened together, and the terminal may be closed when the terminal is closed.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a perspective view showing a lower folder of the embodiment according to the present invention. In the present embodiment, in the lower folder 100 of the clamshell mobile communication terminal in which the car kit connector 130 is formed at the bottom, the cushion rubber 110 is provided at both sides of the upper surface of the lower end. In the opposite case is also possible, in the present embodiment, when the terminal is in the open state, the car kit connector 130 is maintained in the closed state by the carette cover.

3 is a cross-sectional view taken along line AA ′ of FIG. 2 showing a state in which the semi-automatic kit cover is closed according to the present invention. The cushion rubber 110 is composed of a head portion 111 which is exposed to the upper surface of the lower folder to contact the upper folder when the terminal is closed and the shaft portion 112 extending downward from the head portion 111 by a predetermined length. The cushion rubber 110 is mounted on a cushion rubber groove 121 formed to allow the cushion rubber 110 to be inserted into a corresponding portion of an upper surface of the lower folder, and the shaft portion 112 is formed inside the lower folder through a hole. Leads to.

A compression spring 115 that is an elastic member is provided between the cushion rubber 110 and the lower folder case. The compression spring 115 is compressed when the cushion rubber 110 is moved downward and provides a restoring force upward. Therefore, when the terminal is opened, the cushion rubber 110 is pushed out of the cushion rubber groove 121.

Both ends of the carpet cover 131 are connected to the distal end 113 of the shaft 112. As the cushion rubber 110 moves up and down, the carpet cover 131 moves up and down, thus opening and closing a kite connector (not shown) formed outside thereof.

4 is a cross-sectional view taken along line AA ′ of FIG. 2 showing a state in which the semi-automatic carpet cover according to the present invention is opened. As described above, when the terminal is closed, when the upper folder 200 presses the head 111 of the cushion rubber 110, the compression spring 115 is compressed and the cushion rubber 110 moves downward. At this time, the carpet cover 131 connected to the shaft end 113 of the cushion rubber 110 is also moved downwards, so that the I / O connector 133 covered by the carpet cover 131 is moved to the I / O connector ( 131 is exposed with respect to a kite connector (not shown) which is open outwardly in the same position.

In addition, although not shown in the drawing, in another embodiment, when the terminal is in the open state, the carpet cover 131 is positioned above the carpet connector so that the I / O connector 131 is exposed to the carpet connector. When closed, the carpet cover may move down with the cushion rubber 110 to close the carpet connector.

Fig. 5 is a plan view showing a cushion rubber according to the present invention. In order to prevent the carpet cover from being opened even when the terminal is closed, the cushion rubber 110 may be slightly rotated (C) to cover the upper surface of the lower folder so that the cushion rubber 110 is not embedded in the cushion cover groove 121.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and it is common in the field of the present invention that various substitutions and modifications and changes are possible without departing from the technical spirit of the present invention. It will be apparent to those who have knowledge.

Therefore, the mobile communication terminal having the semi-automatic carpet cover using the cushion rubber according to the present invention can alleviate the shock generated when closing the folder and at the same time semi-automatically by opening and closing the folder without opening and closing the carpet cover by hand. It has the effect of being able to open or close.

In addition, there is an effect that can be prevented from being discolored or damaged by allowing the carpet cover to operate in a non-contact manner.
