Detailed implementation manner

[0020] To better illustrate and explain the content of the present invention, the following will be described in conjunction with the accompanying drawings and implementation examples:

[0021] There is Figures 1-3 As shown in the figure, the present invention discloses an automatically opening ice cabinet door body, including a cabinet body 1, the upper end of the cabinet body 1 is hinged with a cabinet door 3, an upper sealing strip 4 is arranged inside the lower surface of the cabinet door 3, a lower sealing strip 2 is arranged inside the upper surface of the cabinet body 1, and an opening mechanism 901 for opening the cabinet door 3 and capable of being manually opened after a power outage is further arranged inside the lower surface of the cabinet door 3, and a power mechanism 902 for providing power for the opening mechanism 901 and capable of being manually operated after a power outage is arranged inside the cabinet body 1.

[0022] Furthermore, the opening mechanism 901 includes a fitting space 6 arranged inside the lower surface of the cabinet door 3, a connecting box body 7 capable of being adsorbed by a magnet is arranged inside the fitting space 6, and a first electromagnet 8 capable of adsorbing the connecting box body 7 is arranged inside the top wall of the fitting space 6.

[0023] Furthermore, a sliding rod 5 is arranged inside the connecting box body 7, the sliding rod 5 penetrates and is slidably connected with a connecting slider 9 capable of being slidably connected with the inner wall of the connecting box body 7, and an ejector rod 10 is hinged on the connecting slider 9.

[0024] Further, the power mechanism 902 includes a power space 26 disposed inside the cabinet body 1. A top rod 10 extending out of the cabinet body 1 is penetrated and slidably connected in the top wall of the power space 26. A top block 25 slidably connected to the power space 26 is fixedly connected to the lower end of the top rod 10. A threaded shaft 11 rotatably connected to the top wall of the power space 26 is penetrated and threadedly connected to the top block 25. A upper transmission disc 23 is fixedly connected to the lower end of the threaded shaft 11. A lower transmission disc 22 is disposed below the upper transmission disc 23. A telescopic shaft 21 is fixedly connected to the lower end of the lower transmission disc 22. The telescopic shaft 21 is slidably connected to a motor shaft 20. Torque can be transmitted between the motor shaft 20 and the telescopic shaft 21. The lower end of the motor shaft 20 is power-connected to a motor 19 fixedly provided at the bottom of the power space 26. The upper transmission disc 23 and the lower transmission disc 22 can be engaged and transmit torque.

[0025] Further, an operating shaft 13 is penetrated and rotatably connected in the side wall of the power space 26. The operating shaft 13 and the threaded shaft 11 are driven by a bevel gear set 24. A protective cover 14 is disposed outside the operating shaft 13.

[0026] Further, a fixed block 12 is fixedly provided on the inner wall of the power space 26. A limiting rod 17 is fixedly provided below the fixed block 12. A connecting plate 18 is penetrated and slidably connected to the limiting rod 17. The connecting plate 18 and the lower transmission disc 22 are fixedly connected by a bearing.

[0027] Further, a second electromagnet 15 is disposed on the lower surface of the fixed block 12. A metal block 16 that is opposite to the second electromagnet 15 and can be adsorbed by the second electromagnet 15 is disposed on the upper surface of the connecting plate 18.

[0028] Specifically, when powered on, the first electromagnet 8 adsorbs the connecting box body 7, and the second electromagnet 15 adsorbs the metal block 16, so that the lower transmission disc 22 moves upward and engages with the upper transmission disc 23;

[0029] At this time, when the motor 19 is started, the motor shaft 20 rotates and drives the telescopic shaft 21 to rotate, and then drives the threaded shaft 11 to rotate through the lower transmission disc 22 and the upper transmission disc 23, and then drives the top block 25 to move upward, and then the top rod 10 moves upward and lifts the cabinet door 3 through the connecting slider 9, realizing the opening of the cabinet door 3. When closing, the motor 19 is reversed, so that the top rod 10 moves downward, thereby driving the cabinet door 3 to close;

[0030] If a power outage occurs when the cabinet door 3 is closed, the first electromagnet 8 loses power and no longer adsorbs the connecting box body 7. At this time, the cabinet door 3 can be directly manually opened to prevent the freezer from being unusable;

[0031] If a power outage occurs when the cabinet door 3 is opened, at this time the ejector rod 10 is located on the upper side, and the cabinet door 3 cannot be manually pressed down to close;

[0032] At this time, it is necessary to open the protective cover 14 and manually rotate the operating shaft 13, so as to drive the threaded shaft 11 to rotate through the bevel gear set 24, realize the descent of the ejector rod 10, and thus enable the cabinet door 3 to be manually closed;

[0033] At the same time of the power outage, the second electromagnet 15 loses power and no longer adsorbs the metal block 16. At this time, the lower transmission disc 22 moves downward and disengages from the upper transmission disc 23, so that the threaded shaft 11 does not need to drive the motor 19 to rotate when rotating, making it easier and more labor-saving to manually rotate the operating shaft 13.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the technical solutions of the present invention have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of each embodiment of the present invention.
