Description

  The present invention is provided in various electronic devices such as a television receiver (hereinafter abbreviated as a television receiver), a monitor device, a personal computer, an audio device, and the like, such as an external input / output terminal unit and a function setting unit. The present invention relates to a lid opening / closing mechanism of an electronic device that is preferably used when a lid that opens and closes a part that is relatively infrequently used.

  For example, television receivers are positioned as important interior appliances, and appearance design is an extremely important element, and many cables and cords described above are connected to connectors provided on the back side. . The TV receiver has a structure in which, as a general usage mode, operations such as power on / off, channel switching or volume adjustment are performed by a remote controller, and these manual switches arranged on the front surface are covered with a lid. It has become.

  By the way, in a conventional television receiver, an external device such as a video recorder is connected, and an electronic game machine can be connected to enjoy a game on a large screen. In a television receiver, a communication terminal function is added along with the start of digital terrestrial broadcasting. Therefore, television receivers have not only connectors for connection cords such as power cords, antenna cables or speakers, but also slits for loading many external input / output terminals and memory cards for connection to external devices. Is provided.

  Also, in various electronic devices, in general, external parts such as switches and connectors are arranged in the opening provided in the housing for the purpose of maintaining the appearance design, preventing mischief or misoperation, and opening the opening. In many cases, a lid that opens and closes is provided. In an electronic device, external input / output terminals, function setting switches, slots or the like that are used relatively infrequently are arranged in an opening that is opened and closed by a lid.

  In an electronic device, the lid body is a part of the exterior surface in the closed state so that it can be easily removed without being loosened or loosened against vibration or the like. It is assembled by an opening / closing mechanism that opens and closes by a simple operation. Various open / close mechanisms have been provided in the past. However, the open / close mechanism is broadly classified into a structure in which the lid is slid with respect to the housing and a structure in which the cover is rotated.

  The slide-type lid opening / closing mechanism generally engages while the lid slides along a slide guide structure formed in the casing, and the lock claw elastically displaces in the lock hole on the casing when the opening is closed. The configuration held by this is a basic aspect. Further, the rotary lid opening / closing mechanism generally has a configuration in which a boss formed on the lid is fitted to a bearing hole formed on the housing and held rotatably.

  In the conventional lid opening / closing mechanism, the lid is generally assembled to a slide guide groove or a bearing hole formed in the housing by bending the lid. Therefore, the conventional lid opening / closing mechanism has a problem that the lid and the boss are damaged when the lid is frequently attached to and detached from the housing. Further, in the conventional lid opening / closing mechanism, the lid removed from the casing may be lost. Furthermore, in the conventional lid opening / closing mechanism, when the vibration is applied in the state where the lid is assembled to the housing, the lid may be rattled. In the conventional lid opening / closing mechanism, for example, an elastic force such as a spring can be applied to prevent the lid from rattling, but the number of parts increases, the structure becomes complicated, and the lid can be attached and detached. There was a problem that it was impossible to do.

  By the way, in television receivers, for example, the development of large and high-performance liquid crystal displays and plasma display displays has been made lighter and thinner, and not only can be used as a stand-alone type by assembling a stand. It is also designed to be installed on a wall surface via a wall bracket. In a television receiver, as described above, the frequency of use is relatively low with the increase in the number of functions. However, arrangement processing of external input / output terminal units, function setting switches, slots, and the like is extremely important.

  In the television receiver, the external input / output terminal section is arranged on the back surface of the housing, and a part of the external input / output terminal section is also arranged on the side panel that is hidden from the front by the front panel body so that it can be opened and closed with the lid. I have to. In a conventional television receiver, the lid opening / closing mechanism for opening / closing the external input / output terminal portion or the like is either the above-described rotation operation type or slide operation type. TV receivers are installed with the screen facing downward for easy viewing when used in a wall-mounted type, but the lid collides with the wall when the lid provided on the side is a rotary opening and closing mechanism. In some cases, opening and closing operations could not be performed. Therefore, in the conventional television receiver, the installation location and the installation attitude are limited as the size of the television receiver increases.

  Accordingly, the present invention has a simple structure with a minimum number of parts, and is easy to use by opening and closing the opening by opening and closing the lid that opens and closes the opening in either the rotational direction or the sliding direction. An object of the present invention is to provide a lid opening / closing mechanism for an electronic device that is improved.

  The lid opening / closing mechanism for an electronic device according to the present invention that achieves the above-described object is a combination of a housing having an opening formed on an exterior surface and a rotatable and slidable combination with the housing. It is comprised from the cover body which opens and closes a part. The lid opening / closing mechanism of the electronic device has an opening in the casing, a pair of slide guide grooves formed on the side wall facing the opening with the sliding direction of the lid as the long axis, and elastic in the thickness direction. A bearing recess is provided in the middle of the opening, and an elastic bearing piece formed on the bottom surface of the opening with the sliding direction of the lid as the major axis, and an end of at least one slide guide groove are opened. Thus, a lid removal guide groove formed in this way is formed. The lid opening / closing mechanism of the electronic device is formed of a boss-like convex portion that protrudes to the side with an arcuate outer peripheral portion at least on the main surface side being slidable in each slide guide groove. A pair of first rotation support shafts fitted to each other, formed on the same inner axis with respect to each of the first rotation support shafts and facing the elastic bearing piece and facing the main surface. A second rotation support shaft portion in which the outer peripheral portion of the substantially half circumference on the side is formed in an arc shape is formed.

  In the lid opening / closing mechanism of the electronic apparatus according to the present invention configured as described above, the lid firmly closes the opening with a lock structure, for example, in the first position with respect to the housing. In the lid opening / closing mechanism of the electronic device, the opening is closed by the lid so that the appearance of the device can be maintained and dust can be prevented from entering or tampering with the inside of the housing. In the lid opening / closing mechanism of the electronic device, the lid is unlocked from the first position and is slid, so that the arc-shaped outer peripheral portion of the first rotating support shaft portion is moved along the groove wall of the slide guide groove. A bearing concave portion in which the arcuate outer peripheral portion of the second rotation support shaft portion slides and slides on the elastic bearing piece portion, and the second rotation support shaft portion constitutes a rotation support point of the elastic bearing piece portion. To a second position to engage. In the lid opening / closing mechanism of the electronic device, when the lid is further slid from the second position, the second rotation support shaft portion elastically displaces the elastic bearing piece portion to get over the bearing recess, and the first The inside of the slide guide groove fitted with the rotation support shaft part is removed to the end part where the guide groove is formed and reaches the third position.

  In the lid opening / closing mechanism of the electronic device, the arcuate outer periphery of the first rotation support shaft and the arcuate outer periphery of the second rotation support shaft formed at different positions on the same axis jointly In addition, the slide guide groove and the bearing concave portion of the elastic bearing piece jointly constitute a bearing hole for rotatably bearing the shaft body. Therefore, in the lid opening / closing mechanism of the electronic device, the opening of the housing is opened by rotating the lid at the second position.

  In the lid opening / closing mechanism of the electronic device, the lid moved to the third position is removed from the casing by removing the first rotating support shaft portion fitted in the slide guide groove from the guide groove. Removed. In the lid opening / closing mechanism of the electronic device, the opening is opened by rotating or sliding the lid with respect to the housing as described above.

  According to the lid opening / closing mechanism of the electronic device according to the present invention configured as described above, it is possible to open the opening portion regardless of whether the rotation operation or the slide operation is performed on the housing. Therefore, it is possible to use switches, external connection terminals, and the like installed in the opening without being restricted by the installation specifications of the device, and the usability can be improved. According to the lid opening / closing mechanism of the electronic device, when the relatively used lid is rotated and used, the lid is prevented from being lost because the lid does not fall off from the casing. According to the lid opening / closing mechanism of the electronic device, since it is composed of the minimum number of parts of the casing and the lid, it is possible to improve the function while suppressing an increase in cost, and the operability is impaired. There is nothing to be done.
