Description

Structure for prevention friction of stand hinge of docking station

The present invention relates to a docking station of a portable hybrid computer, and more particularly, to a component of a docking station to allow data input from a desk or a table through a portable hybrid computer (hereinafter referred to as a portable computer). The arm portion for supporting the cradle portion on which the portable computer is mounted is supported by the hinge portion, and when the arm portion rotates in the front and rear direction of the stand portion according to the user's purpose of use, the arm portion of the stand portion is rotated by the lower end of the arm portion. It relates to a friction preventing structure of the stand hinge portion that can prevent the mounting portion from scratching (scratching).

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.

The docking station manufactured by Toshiba, Japan, as shown in FIG. 1, has a mounting portion 22 on which an electronic device (hereinafter referred to as a portable computer) 1 is mounted, and at the same time, A main body 16 having an expansion means 17 for expanding a function, and a computer connector 12 mounted to the main body 16 in a state connected to the expansion means 17, and mounted to the mounting portion 22; To allow the main body connector 26 and the main body connector 26 to be moved in the left and right directions up and down, and to move in the disengaging direction (rear direction) of the computer connector 12. It consists of a supporting means for supporting.

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 movable position between the loading 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.

However, in the case of the conventional docking station, only the function of allowing the portable computer 1 to recognize the expansion device (device) of the docking station through the portable computer 1 and through the main body connector 26 is provided. On the basis of the direction in which the portable computer 1 is coupled to the main body 16, the portable computer 1 mounted on the main body 16 is rotated in the front-rear direction of the main body 16 according to a user's purpose of use. It has a single member structure that cannot be used so that the portable computer 1 is always used as it is, regardless of the user's working position or a specific place, or the entire docking station equipped with the portable computer 1 is used. There has been a very limited problem in using the portable computer 1 coupled to the docking station, such as having to move to a user's working position.

The present invention has been made in order to solve the above problems, the arm portion for supporting the cradle portion mounted on the portable computer is rotated in the front and rear direction of the stand portion according to the user's purpose of use through the rotating structure by the hinge. At this time, the arm mounting portion of the stand portion is prevented from being scratched (scratched) by the lower end of the rotating arm portion, and fine powders generated by the scratching of the arm mounting portion are mixed in the stand. The purpose is to prevent it.

In addition, there is another object to prevent the fine dust or foreign matter is mixed into the stand portion through the gap between the lower end of the arm portion and the arm mounting portion coupled by the hinge.

The object of the present invention, in the stand hinge portion anti-friction structure of the present invention to insert and fix the arm seat cover in the arm seat in order to prevent the arm seat portion of the stand portion from being scratched through the lower end of the rotating arm portion As can be solved by the above, it will be described in detail with reference to the accompanying drawings.
