Description

Stand cover structure using prevention bending of docking station

The present invention relates to a docking station of a portable hybrid computer, and more particularly, an expansion device capable of simultaneously serving as an expansion function of a web pad system mounted on a cradle and a base of the cradle. In order to prevent the inflow of fine dust or contaminants into the lower case where the stand main board and the center of gravity plate are fixed, the upper cover which is screwed on the upper case by the high temperature generated by the expansion device or the stand main board It relates to a bend prevention stand cover to prevent the upper cover is bent.

In general, in order to put a portable computer on a desk or a table and conveniently input data, a docking station for mounting the portable computer may be provided. Such a docking station may include a portable computer manufactured by each manufacturer. In order to provide a user with a separate docking station according to its shape, special purpose of use, and driving conditions, the docking station structure manufactured by each manufacturer is composed of different structures. As an example of the docking station manufactured by the present invention, a structure of a functional expansion device of an electronic device manufactured by Toshiba, Japan (JP-A-5-189086, hereinafter referred to as a docking station) will be described.

As shown in Fig. 1, the docking station has a mounting portion 22 to which an electronic device (hereinafter referred to as a portable computer) 1 is mounted, and at the same time, expands the function of the portable computer 1. A main body 16 having means 17 and a computer connector 12 mounted on the main body 16 in a state of being connected to the expansion means 17 and detachably protruding from the mounting portion 22. Support means for supporting the formed main body connector 26 and the main body connector 26 to move in the left and right and up and down direction, and at the same time to move in the disengaging direction (front and rear direction) of the computer connector 12. Consists of.

As shown in FIG. 2, the supporting means pushes the connector holder 28 to which the main body connector 26 is fixed, and the connector holder 28 to a standby position along the disengaging direction of the computer connector 12. And a support member for supporting the movement between the retracted positions, and pressing means for pressing the connector holder 28 fixed to the main body 16 toward the standby position.

As shown in FIG. 2, the support member is fixed to the support bracket 32 on which the connector holder 28 is fixedly supported by a screw, and to the support bracket 32 around the pressing means. And a support frame 40 to support the support bracket 32 so that the support bracket 32 to which the connector holder 28 is fixed by the pressing means can move in the distal direction, and the support bracket. It consists of the guide sleeve 52 which is inserted in the guide hole 38 which penetrated the 1st vertical part 32b of the 32, and is fixed to the said support frame 40 by a screw.

As shown in Figure 2, the pressing means is composed of a leaf spring 46 formed in a predetermined form. In addition, a plurality of earth units 70 are fixed at predetermined positions of the main body 16 mounting part 22 to prevent component damage of the portable computer 1 mounted on the main body mounting part 22 during overcurrent.

In the main body 16, an ejector mechanism (not shown) for separating the portable computer 1 mounted on the main body mounting portion 22 is provided, and the ejector mechanism is shown in FIG. It is connected to the press lever 58 provided at the lower left and right ends of the main body connector 26, and when the operation knob 60 of the ejector mechanism is operated in the X direction, the press lever by the mechanical linkage of the ejector mechanism. While the 58 is operated, the portable computer 1 mounted on the main body mounting portion 22 is configured to be separated from the main body 16.

In this case, as shown in FIG. 3, when an external force acts while the portable computer 1 is coupled to the main body 16 which is a conventional ducking station, the tapered cylindrical portion of the guide sleeve 52 and the support bracket ( The main body connector 26 coupled with the computer connector 12 is moved up and down or left and right by a predetermined gap formed between the guide holes 38 of the 32, and the external force is canceled to offset the computer connector 12 and the main body connector 26. ) Damage is prevented.

However, in the case of the conventional docking station, in order to expand the functions of the portable computer 1 carried by the user, a hard disk or a floppy disk, a CD-ROM, or the like, which is an expansion means, is fixed in the docking station. When the portable computer 1 is used for a long time while the portable computer 1 is coupled to a docking station where a hard disk, a floppy disk, a CD-ROM, or the like is fixed, the portable computer 1 is electrically connected to the portable computer 1 through the docking station. As a high temperature is generated in the interfaced hard disk, floppy disk, CD-ROM, etc., there is a big problem that the outer case of the docking station is bent by the high temperature of the expansion means.

Furthermore, in order to prevent inflow of fine dust or the like in the lower case in which the expansion means is built, the upper cover fixed to the lower case is relatively thin in the outer case of the docking station, and thus occurs in the expansion means. There was also a big problem that the high heat is bent faster than the lower case.

Therefore, in recent years, by applying a material that can quickly release the high heat generated by the expansion means to the existing outer case to the outside to protect the outer case of the material weak to the heat, or to withstand the high temperature of the expansion means It is required to develop an outer case of a heat resistant structure such as designing a structure having a structure, and at the same time, the development of a material itself that can prevent the case itself from bending due to the high heat generated by the expansion means is required.

The present invention has been made in order to solve the above problems, the expansion device, the stand main board, the center of gravity plate, etc. to secure the function of expanding the function of the web pad system mounted on the cradle and the base of the cradle The upper cover which is screwed on the upper case of the lower case to prevent the inflow of fine dust or contaminants in the lower case to prevent the upper cover from being bent by the high temperature generated in the expansion device or the stand motherboard There is this.

This object of the present invention can be solved by the warp-proof stand cover structure of the present invention in which the warp plate is attached to the top of the top cover to prevent the top cover from being bent by heat generated from the expansion device or the stand main board. Will be described in detail below with reference to the accompanying drawings.
