BACKGROUND OF THE INVENTION
The present invention relates to an electronic apparatus having an open / close lid used to cover an external connection connector or the like.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a portable electronic device such as a notebook personal computer is provided with a connector for connecting to an external peripheral device or the like, and an open / close lid is provided to prevent entry of dust or the like when not connected to the connector.
[0003]
A conventional electronic device having an opening / closing lid will be described below with reference to the drawings.
FIG. 3 is an external perspective view of a notebook computer provided with an opening / closing lid, and FIG. 4 is a configuration diagram of the opening / closing lid when the opening / closing portion of the notebook computer is viewed from the inside of the device. In the figure, reference numeral 1 denotes a main body of a notebook personal computer, 1a denotes a rectangular opening formed on the rear surface of the main body 1, and a connector 2 for connecting to an external device is provided inside. FIG. 3 shows a state in which the stored opening / closing lid is pulled out for easy understanding. Reference numeral 11 denotes a resin opening / closing lid, and the lid portion 11a has substantially the same size in accordance with the shape of the opening 1a. Cylindrical pins 11b are provided in the vicinity of the ends of the two opposing sides of the lid portion 11a. Reference numeral 12 denotes a metal spring plate for holding the pin 11b, which has an elastic force, and is provided with a circular arc part 12a and a hole 12b to be attached to the end part with a screw (not shown).
[0004]
The opening / closing operation of the opening / closing lid of the notebook computer configured as described above will be described. The opening / closing lid 11 housed inside the main body 1 can be pulled out only by sliding in the A direction because the pin 11 b is pressed by the spring plate 12. The movement of the opening in the back direction is stopped by the arc portion 12a. The opening side is stopped by a stop portion (not shown), and the pin 11b is rotated at that position as a fulcrum, and the direction of the lid portion 11a is changed to the state shown by the one-dot chain line in the figure, thereby closing the opening portion 1a. Since the opening / closing lid 11 is pressed by the spring plate 12, the pin 11b can be rotated with little movement.
[0005]
[Problems to be solved by the invention]
In recent years, in particular, portable notebook personal computers have been required to be lighter, and individual parts have to be lightened. On the other hand, the spring plate in the structure of the conventional open / close lid needs to always exert an urging force, so that the urging force decreases due to secular change and frequency use, or the spring plate simply holds the pin. For this reason, an opening / closing failure or the like due to the unstable rotational position of the lid portion has occurred.
[0006]
An object of the present invention is to provide an electronic device that simplifies the structure of such an opening / closing lid, eliminates parts such as a metal spring plate, and solves both weight reduction and opening / closing failure.
[0007]
[Means for Solving the Problems]
In order to solve this problem, according to the present invention, a slit is provided in the vicinity of two opposite sides of the opening / closing lid to generate an elastic force, and a convex portion is provided in a groove for guiding the guide pin of the opening / closing lid to provide a click feeling. The rotation fulcrum position is stabilized.
[0008]
Thereby, the spring plate can be abolished and the weight can be reduced, and the opening / closing failure of the opening / closing lid can be reduced.
[0009]

[0012]
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Embodiment 1)
FIG. 1 is an external perspective view of an opening / closing part of a notebook computer, which is an electronic device having an opening / closing lid according to an embodiment of the present invention, as viewed from inside the device, and FIG. 1 (a) shows a state in which the opening / closing lid is opened. FIG. 1B shows a closed state. In the figure, 1b is a guide groove provided in the main body 1, which is formed in the direction from the opening 1a to the inside of the device, and the end of the opening 1a is closed in an arc shape. Reference numeral 3 denotes a resin-made opening / closing lid. Cylindrical guide pins 3b are provided in the vicinity of the opposite ends of the lid portion 3a and are fitted in the guide grooves 1b. Reference numeral 3c denotes a slit formed in parallel to the side where the guide pin 3b is provided, whereby an elastic force is generated between the lid portion 3a and the guide pin 3b. Further, a convex portion 1c is provided in the guide groove 1b with a dimension substantially equal to the outer diameter of the guide pin 3b from the end portion on the opening 1a side. The height of the convex portion 1c is such that the guide pin 3b can be overcome by the elastic force of the slit 3c.
[0013]
The opening / closing operation of the opening / closing lid of the notebook computer configured as described above will be described. Since the guide pin 3b is engaged with the guide groove 1b, the open / close lid 3 slides along the guide groove 1b, and the lid 3a is pulled out of the opening 1a. At this time, the guide pin 3b once hits the convex portion 1c in the guide groove 1b, but can get over the convex portion 1c by the elastic force by the slit 3c. Thereafter, the movement in the direction of the opening 1a is stopped by the end of the guide groove 1b which is closed in an arc shape. At that position, the guide pin 3b is rotated around the fulcrum, the direction of the lid 3a is changed to the direction of FIG. 1B, and the opening 1a is closed. At this time, the position of the opening / closing lid 3 is maintained because the guide pin 3b is sandwiched between the end portion of the guide groove 1b and the convex portion 1c with substantially the same size, the rotation fulcrum does not move, and the opening / closing operation is stabilized. FIG. 2 shows the positional relationship between the guide groove 1b and the guide pin 3b at this time. Moreover, since a click feeling is created when the guide pin 3b gets over the convex portion 1c, the rotation fulcrum position can be clearly felt.
[0014]
Thus, since the rotation fulcrum position of the opening / closing lid is stabilized and a click feeling is created, the rotation fulcrum position can be clearly sensed, and opening / closing defects can be reduced.
[0015]
Further, since a spring plate or the like is not required for the opening / closing structure, the structure is simplified and the weight of the electronic device is helped.
[0016]
In this embodiment, the slit is provided in the opening / closing lid. However, if the resin material itself of the opening / closing lid has elasticity, it is not necessary to provide the slit.
[0017]
【The invention's effect】
As described above, according to the present invention, a slit is provided in the vicinity of two opposite sides of the opening / closing lid to generate an elastic force, and a convex portion is provided in the groove for guiding the guide pin of the opening / closing lid, thereby providing a click feeling. In addition to being able to reduce the opening / closing failure of the opening / closing lid by stabilizing the position of the take-out rotation fulcrum, it has a simple structure and the metal spring plate can be abolished. .
