Description

Tray opening and closing device

technical field

The present invention relates to a tray opening and closing device, and more particularly, to a heart-shaped cam for opening and closing a tray for a vehicle.

Background technique

Generally, a vehicle tray is composed of a storage box for storing predetermined items and a door for opening and closing the box.

The tray is usually provided on the dashboard of the vehicle.

According to the conventional vehicle tray, as shown in FIGS. 7a to 7c , it includes: a storage box 11 with an opening on one side and a storage space inside; and a door 30 that opens and closes the opening. In addition, the storage box 10 and the door 30 are connected by a hinge shaft 40 , and a coil spring (not shown) is provided on the hinge shaft 40 to apply elastic force to the door 30 to maintain the open state. In addition, a heart-shaped cam 20 is formed on one side of the storage box 10 , and a rotating pin 31 guided by the heart-shaped cam 20 to move is provided on one side of the door 30 .

Therefore, when the door 30 closes the opening of the storage box 10, the rotating pin 31 is located at A1 of the heart-shaped cam 20. The elastic force of the coil spring rotates counterclockwise with the hinge shaft 40 as the center, and at this moment, the rotating pin 31 moves to the A2 position of the heart-shaped cam 20, and the door 30 is opened.

And, when the door 30 is opened, if the door 30 is pushed clockwise, the rotating pin 31 moves to the A1 position of the heart-shaped cam 20, and the door is closed.

In addition, for the operation of the door, the rotary pin 31 is inserted into the guide rail of the heart cam 20 to move, and a precise running gap (GAP) is required between the guide rail and the rotary pin 31 .

Therefore, if the repeated opening and closing operation of the door cannot maintain a predetermined running gap, there is a problem that the pivot pin 31 is detached from the guide rail. And, actually can produce the problem that revolving pin 31 does not move to the correct position of heart-shaped cam 20 and can't open the door.
