Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening / closing mechanism for opening / closing an insertion opening formed in a front panel of a vehicle-mounted electronic device with a door member, and more particularly, the door member slides along the front surface of the front panel. The present invention relates to an operating door opening / closing mechanism.

[0002]

2. Description of the Related Art In recent years, in a vehicle-mounted electronic device such as a car navigation system, a disk insertion slot is opened in a front panel attached to the front of the device body, and a disk-shaped medium such as a CD-ROM is inserted from the disk insertion slot. Products designed to insert and discharge garbage are widely used. Since the disc insertion slot must be closed except when inserting or discharging a disc-shaped medium in order to prevent intrusion of dust or the like, a door which can expose or cover the disc insertion slot at any time has been conventionally used. Various opening and closing mechanisms are employed.

As an example of such a door opening / closing mechanism, a door member can be slid along a concave curved surface provided on the front surface of a front panel so that a click feeling is generated when the door member slides. A sliding door opening and closing mechanism has been proposed. This door opening and closing mechanism closes the disc insertion slot when the door member is in the upright position in the curved surface, and the door member slides along the curved surface and projects obliquely downward. Sometimes, the disc insertion opening is exposed, and the opening and closing operation of the door member is performed with a click feeling, so that it is preferred in terms of design, operability, space factor, and the like.

[0004]

However, in the above-mentioned conventional sliding door opening / closing mechanism, a pair of members which synchronously rotate in opposite directions with the sliding operation of the door member are provided as a mechanism for promoting the opening / closing operation of the door member. A large number of parts such as a rotary arm and a wire spring stretched between a pair of drive pins implanted in both of the rotary arms are required. In particular, the wire spring is directly hooked to the drive pin. However, since both ends of the wire spring are hung on the relay member inserted into both drive pins, there is a problem that the structure is complicated and the number of parts increases.

[0005]

According to the present invention, a pair of rotating arms for synchronizing the movements of both ends of a door member are bridged by a synthetic resin rod member, and a spring deformed portion is integrally formed on the rod member. I decided to. When such a rod member is used, the rod member can be directly inserted into a pair of drive pins provided on each of the rotating arms, and the rod members elastically urge the two drive pins in a direction approaching each other. The structure is simplified and the number of parts is reduced.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a door opening / closing mechanism for a vehicle-mounted electronic device according to the present invention, a front panel having a medium insertion port is provided.
A door member slidably disposed along the front surface of the front panel, wherein a sliding operation of the door member is performed in a door opening / closing mechanism of an in-vehicle electronic device that opens and closes the insertion opening by a sliding operation of the door member. A pair of rotating arms that rotate in synchronization in opposite directions with each other, and a synthetic resin rod member that bridges a pair of drive pins provided on each of the rotating arms. A spring deforming portion for urging the two drive pins in a direction to approach each other is integrally formed.

The door opening / closing mechanism configured as described above slides the door member in one direction so that the first and second drive pins pass a straight line connecting the rotation centers of the respective rotation arms. Until both drive pins pass through the straight line, the spring deforming portion of the rod member gradually increases the amount of deformation to generate a force that hinders the rotation of both rotating arms. After passing through, the spring deformed portion of the rod member tries to return to the original state, and generates a force that promotes the rotation of both rotating arms. Therefore, immediately after the click feeling is felt by the operator, the door member is reliably opened (in the case of the opening operation) or closed (in the case of the closing operation). Here, the rod member can be directly inserted into the pair of drive pins, and the rod member elastically urges both drive pins in a direction approaching each other, so that the structure is simplified and the number of parts can be reduced.

In the door opening / closing mechanism for a vehicle-mounted electronic device according to the present invention, the spring deformed portion is integrally formed near the center in the longitudinal direction of the rod member.

In the door opening / closing mechanism for a vehicle-mounted electronic device according to the present invention, the spring deformed portion is formed in a crank shape.

In the door opening / closing mechanism for a vehicle-mounted electronic device according to the present invention, the two rotating arms are rotatably supported by a bracket fixed to the back surface of the door member, and the two driving pins are attached to the front panel. The opened through-hole was inserted and projected to the back of the front panel, and the hole of the rod member was inserted into the two drive pins from the back of the front panel.

In the door opening / closing mechanism for a vehicle-mounted electronic device according to the present invention, the two rotating arms are connected to each other by a long hole and an engaging pin at the center of each rotating shaft.
