[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electronic device having a lid mechanism, and more particularly to an electronic device such as a notebook computer having a lid mechanism for attaching / detaching a battery, a hard disk drive device, a memory, or the like.
[0002]
[Prior art]
In recent years, portable electronic devices such as notebook computers have been reduced in size and weight, and portability has been improved. Along with this, driving opportunities with batteries have increased, and batteries have been mounted in lid mechanisms that can be opened and closed with one touch so that the batteries can be easily replaced. In addition, in order to facilitate the addition and replacement of hard disk drive devices, memory, and other parts for maintenance and performance improvement, these parts are housed in a lid mechanism, and these operations are performed by opening and closing the lid. It's getting easier. In the past, these lids were generally placed on the bottom surface of portable electronic devices, but from the standpoint of easy attachment and detachment, the top and side surfaces can be operated without reversing the device. It is becoming more and more to arrange this. Along with this, an opening / closing lid is arranged on the upper surface of the cabinet, and the battery can be exchanged and maintained by opening / closing the lid.
[0003]
Hereinafter, an electronic apparatus having a conventional lid mechanism will be described with reference to the drawings.
3 and 4 are external perspective views (partly in section) of the opening / closing lid portion of a conventional electronic device. FIG. 3 shows a state in which the opening / closing lid is opened, and FIG. 4 shows a state in which the opening / closing lid is closed. In the figure, 21 is a main body cabinet of an electronic device, 2 is a battery built in the main body cabinet 21, 23 is an open / close lid disposed substantially on the same plane as the upper surface of the main body cabinet 21, and rotates on the main body cabinet 21 around a shaft 23a. It is attached as possible. The battery 2 has a structure that can be detached from the main body of the electronic device by opening and closing the opening / closing lid 23. The battery 2 is electrically connected to a circuit board (not shown) in the main body cabinet 21. The open / close lid 23 has a lock mechanism (not shown) for being fixed to the main body cabinet 21 in a closed state.
[0004]
The operation of the conventional electronic apparatus configured as described above will be described below. In a normal use state, the opening / closing lid 23 is fixed to the main body cabinet 21 in a closed state by a lock mechanism. When the battery 2 is replaced, the locking mechanism is released, the shaft 23a attached to the main body cabinet 21 is rotated about the shaft 23, the opening / closing lid 23 is opened, and the battery 2 is attached / detached. When the opening / closing lid 23 is closed (normal state), it is necessary to make the gap with the main body cabinet 21 as small as possible from the viewpoint of preventing the entry of dust and water droplets and the appearance. 21 so as to sink into the inside. Further, the opening / closing lid 23 is required to have an opening / closing angle of 90 ° or more from the viewpoint of easy attachment / detachment of a battery or the like.
[0005]
[Problems to be solved by the invention]
However, in such an electronic device having the above conventional lid mechanism, in order to open the opening / closing lid by 90 ° or more, the shaft 23a and the opening end face of the main body cabinet 21 need to be separated from each other, and in a closed state. In order to prevent water droplets and dust from entering and improve the appearance, the end 23b of the opening / closing lid 23 is embedded in the main body cabinet 21, so that the end 23b is brought into the main body cabinet 21 when the opening / closing lid 23 is opened / closed. Rotate as if diving. Therefore, the dimension L in the drawing required for the rotation of the end 23b is increased, and this space is wasted in a portable electronic device that must use the space effectively. Further, since the opening / closing lid 23 is not fixed in the state where the opening / closing lid 23 is opened, there is a problem that the opening / closing lid 23 is closed during the replacement work of the battery 2.
[0006]
The present invention solves the above-described conventional problems, and when the open / close lid is closed, a groove or a gap generated between the cabinet and the main body cabinet is made as small as possible. Reduces wasted space by opening and closing without diving into the main unit cabinet, making effective use of space in portable electronic devices, and preventing problems such as the lid opening and closing spontaneously when closing batteries etc. The purpose is to do.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, an electronic device having a lid mechanism according to the present invention includes an open / close lid attached to the main body casing on substantially the same surface, one end attached to the open / close lid, and the other end attached to the main body case. A torsion spring that urges the opening / closing lid in a direction to draw the opening / closing lid toward the main body housing, and the opening / closing lid has a rotation fulcrum that is rotatably attached to one end of the torsion spring inside the end surface, The end face is slid on a flat part provided in the main body casing, and the opening / closing operation is performed.
[0008]
With the above configuration, when the opening / closing lid is closed, the opening / closing lid is attracted to the main body housing by the torsion spring, so that the gap between the main body housing and the opening / closing lid can be kept small. Etc. can be prevented. In addition, when opening and closing, the opening and closing lid moves so that it slides on the top surface of the main body casing, so the end of the opening and closing lid does not sink inside the main body casing, and no extra space is required for opening and closing. Effective use of space becomes possible. In addition, when the opening / closing lid is opened at an angle (90 ° or more), the urging force acts not in the closing direction but in the direction of opening the opening / closing lid due to the rotational force of the torsion spring. The problem of closing the open / close lid is also eliminated.
