[0036] The working principle of the rear door opening and closing mechanism of the above-mentioned three-way opening armrest box is as follows:

[0037] 1. Press the button and the connecting block moves forward; the connecting block pushes the two rear connecting rods forward through the two rear pins, and the two rear pins move forward until they exit the pin holes on the rear protrusion.

[0038] 2. The left rear linkage moves forward, pushing the left reversing lever to rotate clockwise, the left front linkage moves backward, and the left front pin moves backward;

[0039] 3. The right rear linkage moves forward, pushing the right side reversing lever to rotate counterclockwise, the right front linkage moves backward, and the right front pin moves backward;

[0040] 4. Once both front pins have disengaged from the pin holes on the front protrusion, lift the cover. The cover will rotate around the door hinge to open the armrest box.

[0041] 5. After the armrest box is opened, release the button. The torsion spring of the front link pushes the front link to return to its original position. The front link moves away from the side reversing lever, and the rear link also moves away from the side reversing lever.

[0042] 6. When you need to close the armrest box, press the back button and repeat the above process to close the box cover; release the back button, the front linkage torsion spring pushes the front linkage to reset, and the rear pin and front pin are re-inserted into the corresponding pin holes.

[0043] The working principle of the left-side door opening and closing mechanism of the above-mentioned three-way opening armrest box is as follows:

[0044] 1. Press the left button, the left button pushes the left movable rod; the left movable rod moves to the right along the left guide groove, causing the left front pin to move to the right;

[0045] 2. As the left front pin moves to the right, it presses against the left front connecting rod through the left front pin hole, causing the left front connecting rod to move backward, which in turn drives the left front pin to move backward and pushes the left side reversing lever to rotate clockwise. The left rear connecting rod moves forward and drives the left rear pin to move forward.

[0046] 3. Simultaneously, the left-side button pushes the stop block of the left-side door hinge assembly to the right, thereby causing the left-side door hinge assembly to move to the right; the left-side door hinge moves to the right;

[0047] 4. The connecting end of the left door hinge assembly moves to the right, causing the front reversing lever to rotate counterclockwise, which in turn causes the connecting end of the right door hinge assembly to move to the left, and the right door hinge to move to the left.

[0048] 5. After both left and right door hinges have exited their corresponding door hinge holes, and the left front pin and left rear pin have exited their corresponding pin holes, open the case cover and rotate the case cover around the right front pin and right rear pin.

[0049] 6. After the armrest box is opened, release the button on the left side. The torsion springs of the two movable rods push the corresponding movable rods to reset, and the connecting ends of the two door hinge assemblies are moved away from the side reversing lever; the two reset springs drive the corresponding stops to reset.

[0050] 7. When you need to close the armrest box, press the left button and repeat the above process to close the box lid; release the left button, the two moving rod torsion springs push the corresponding moving rods to reset, and the two reset springs drive the corresponding stops to reset; both left and right door hinges are inserted into the corresponding door hinge holes, and the left front pin and the left rear pin are inserted into the corresponding pin holes.

[0051] The working principle of the door opening and closing on the right side is the same.

[0052] This invention solves the technical problems of complex structure, cumbersome operation, and inability to open from the rear in general armrest boxes. It is easy to operate, simple in structure, and can be opened and closed in three directions. The vehicle refrigerator of this invention is installed in the armrest box between the driver's seat and the passenger seat. The refrigerator door can be opened and closed in three directions, making it convenient for the driver, passenger, and rear passengers to open the refrigerator door at will.

[0053] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description
