1. Field of the Invention
The present invention relates to a tray locking structure of a vehicle in which when a button of a locking part installed in a door of the vehicle is pulled forward, the tray is released from the locked state such that the door of the tray is prevented from opening due to external shock and accident is prevented
2. Description of the Related Art
Generally, an instrument panel of a vehicle includes various meters in the side of a driver seat and a glove box in the side of a front passenger seat.
Between the driver seat and the front passenger seat a center facea is formed. On the upper side of the center faced, an upward opening tray is installed to accommodate glasses.
FIG. 1 is an exploded perspective view illustrating a conventional tray of a vehicle whose button is pressed down to open it, FIG. 2 is a view illustrating the button in a closed state of the tray in FIG. 1, and FIG. 3 is a view illustrating the button pressed down in the state shown in FIG. 2.
As shown in the drawings, the tray 1 includes a housing 10 installed in the upper side of the instrument panel of a vehicle, a door 20 hinged to the upper side of the housing 10 to open the upper side of the housing 10, and a cover 30 for covering the upper side of the door 20.
The housing 10 has an opened upper side, an accommodating room 11 for accommodating articles, and an installation recess 12 for accommodating a button of the door 20.
The rear side of the door 20 is rotatably hinged to a coupling plate 16 formed in the rear side of the housing 10 directly or by a bracket. The front side of the door 20 has a button unit 21 to be inserted into and locked by or released from the installation recess 12.
The cover 30 is coupled with the upper side of the door 20 and is formed with a through-hole for a part of the button unit 21 to protrude through.
Meanwhile, the button unit 21 includes a button 22, a hook 23, and a fixed plate 24.
The fixed plate 24 is fastened to an installation hole 29 formed in the front side of the door 20 by screws, the hook 23 having a locking protrusion 23a formed in the end thereof is rotatably coupled in the fixed plate 24 by pins 25, the button 22 traveling up and down is coupled with the upper side of the hook 23.
Pin springs 25a are installed to the pins 25 positioned at the places where the hook 23 and the fixed plate 24 are coupled with each other so that when pressure against the button is released, the button 22 can be returned to the original position.
Moreover, into the installation recess 12 of the housing 10, a supporting box 14 having a spring 13 is inserted to push the hook 23 upward.
Thus, the button unit 21 is assembled and installed to the door 20, the cover 30 is coupled with the upper side of the door 20, and the door equipped with the cover 30 is hinged to the housing 10.
In this case, in the state of the tray 1 being closed as shown in FIG. 2, the locking protrusion 23a formed in the lower end of the hook 23 of the button unit 21 is fixed to a locking step 15 of the housing 10.
In the above state, as shown in FIG. 3, when a user presses the button 22 down, the hook 23 rotates about the pins 25 so that the locking protrusion 23a is released from the locking step 15.
Thus, due to the elastic restoring force of the spring 13 installed in the installation recess 12 of the housing 10, the supporting box 14 pushes the hook 23 upward so that the door 20 is released from the locked state and protrudes upward.
At that time, when the force applied to the button 22 is released, due to the pin springs 25a, the hook 23 is returned to its original state and the button 22 is returned to its original state.
However, when shock is applied to the instrument panel in which the tray is installed, the ring of the button unit is minutely rotated in the direction where the shock is applied. Generally, since the shock is generated from the front side of the tray, the ring rotates forward due to the shock, so that the locking protrusion of the ring is separated from the locking step to release the locked state of the door.
