[0023] The invention will now be further described with reference to the accompanying drawings.

[0024] The refrigerator of the present invention includes a cabinet 1 and an anti-tipping device installed on the cabinet 1. A compressor support plate is installed at the bottom of the cabinet 1, and a control board 2, an infrared module (not shown), and an angle detector (not shown) are installed on the upper surface of the cabinet 1. The anti-tipping device includes a motor 3 and a folding connecting rod installed on the compressor support plate.

[0025] The control board 2 is connected to the infrared module via wires, the control board 2 is connected to the angle detector via wires, and the control board 2 is connected to the motor 3 via wires.

[0026] Motor shaft 4 is mounted on motor 3, and ejector shaft 5 is threadedly connected to motor shaft 4.

[0027] The folding linkage includes a sliding part 40, a cantilever part 41, and a connecting part 42 connected to the sliding part 40 and the cantilever part 41. The end of the sliding part 40 near the ejector shaft 5 is pivotally connected to one end of the cantilever part 41 through a first rotating shaft 6. The first rotating shaft 6 is fixedly connected to the ejector shaft 5, and a retaining ring 7 is sleeved on the first rotating shaft 6.

[0028] One end of the connecting part 42 is pivotally connected to the cantilever part 41 via the second pivot 8, and the other end of the connecting part 42 is connected to the sliding part 40 via the third pivot 9. The third pivot 9 can slide along the groove 10 provided on the sliding part 40 away from the end of the first pivot 6.

[0029] A slide rail 11 is mounted on the lower surface of the compressor tray, and a groove (not shown) is recessed on the lower surface of the sliding part 40 to slide and accommodate the slide rail 11.

[0030] In this invention, motor 3 is a DC motor, and there are two of them, namely left and right DC motors, which are used to control the opening and closing of the left and right folding linkages respectively.

[0031] The DC motor of this invention is a DC motor with a gearbox, and the operating voltage of the DC motor is about 6V-12V.

[0032] The angle detector in this invention adopts the working principle of an angle sensor, which can sense the angle to be measured and convert it into a usable output signal.

[0033] The working steps of the anti-tipping device of the present invention are as follows:

[0034] (1). When the box 1 is tilted more than 10° relative to the ground, the angle detector on the upper surface of the box 1 sends a signal to the control board 2, and the control board 2 sends an open signal to the infrared module;

[0035] (2). The microcontroller in the infrared module transmits the open signal to the motor 3 at the bottom of the box. The motor 3 drives the ejector shaft 5 to push the first rotating shaft 6, which in turn pushes the recess in the sliding part 40 to slide along the slide rail 11.

[0036] (3). When the sliding part 40 is pushed to the side of the refrigerator, the cantilever part 41 can be unfolded due to the action of the retaining spring 7, the third rotating shaft 9 slides along the slide groove 10, and the protective function is activated.

[0037] (4) When the box 1 is 0° relative to the ground, the angle detector on the upper surface of the box 1 sends a shutdown signal to the control board 2. The control board 2 sends the shutdown signal to the infrared module. The microcontroller in the infrared module transmits the shutdown signal to the motor 3 at the bottom of the box. The motor 3 rotates in the opposite direction, the cantilever 41 is retracted, and the recess in the sliding part 40 slides in the opposite direction along the slide rail 11 to the bottom of the compressor tray, and the protection function is turned off.

[0038] The anti-tipping device of this invention uses a touch-sensitive refrigerator control panel, which then sends open and close signals to an infrared module. After receiving the signal, the microcontroller in the infrared module transmits the signal command to a motor at the bottom of the refrigerator. The motor is connected to a folding linkage at the bottom of the refrigerator, which in turn drives the folding linkage to open. If the protective function needs to be turned off, the folding linkage will automatically fold back.

[0039] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
