BIDIRECTIONAL OPENING/CLOSING DEVICE, AND ARMREST BOX AND VEHICLE

The present invention relates to the field of vehicles. Provided a bidirectional opening/closing device, an armrest box and a vehicle. The bidirectional opening/closing device includes a base, a plate, a trigger mechanism and two locking mechanisms; each locking mechanism includes a lock arm with a hinged end and a free end, the lock arm is installed on the base by the means of the hinged end, the lock arm and the base can be locked or unlocked, and the lock arm can rotate around the hinged end when the lock arm and the base are unlocked; the two lock arms are arranged symmetrically and in parallel, and the free ends of the two lock arms face opposite directions, such that the two lock arms have opposite directions of rotation. The trigger mechanism is installed on the plate, and the trigger mechanism can selectively unlock one lock arm from the base, such that the lock arm can drive the plate to rotate around the hinged end of the lock arm. The bidirectional opening/closing device can achieve bidirectional opening/closing, and when applied to an armrest box of the vehicle, same can meet the requirements of a passenger in a rear row for storing and taking out an object.
