[0095] See also Fig.12 In some embodiments, a mounting cavity 321 may be further provided in the first gear shaft 32. The mounting cavity 321 may be coaxially arranged with the second gear shaft 24 so that the second gear shaft 24 can be precisely docked with the mounting cavity 321 in the first gear shaft 32.

[0096] In some embodiments, the shape of the installation cavity 321 may match the shape of the second gear shaft 24. The cross-sectional shapes of the second gear shaft 24 and the installation cavity 321 may be circular, rectangular, plum blossom-shaped, or any other shape.

[0097] When the second gear shaft 24 is accommodated in the mounting cavity 321, a small gap can be maintained between the inner wall of the mounting cavity 321 and the outer wall of the second gear shaft 24 to ensure that the second gear shaft 24 can be firmly inserted into the mounting cavity 321 without loosening or shaking.

[0098] See also Fig.12 In some embodiments, the inner wall of the installation cavity 321 may be provided with a key groove 322. There may be a plurality of key grooves 322, and the plurality of key grooves 322 may be spaced apart from each other, and the plurality of key grooves 322 may be evenly distributed along the inner wall of the installation cavity 321, so that the cross section of the installation cavity 321 is configured into a plum blossom shape.

[0099] See also Fig.10 In some embodiments, a protrusion 241 may be provided on the outer peripheral wall of the second gear shaft 24. A plurality of protrusions 241 may be provided, and the plurality of protrusions 241 may correspond to the plurality of key slots 322 one by one.

[0100] The position and size of each protrusion 241 can be completely matched with the corresponding keyway 322, so that it can be accurately embedded in the keyway 322 during connection. It can prevent the gear shaft from rotating or disengaging during operation, and provide higher transmission efficiency for the gear shaft.

[0101] See also Figure 1 and Figure 3 In some embodiments, the control system may further include a control button 40. The control button 40 may be disposed on the front side of the cabinet door 20 so that the user can easily access it at any position.

[0102] In some embodiments, the control button 40 can be electrically connected to the driving member 30, and the user can press the control button 40 to make the control button 40 send a door opening signal to the driving member 30. The driving member 30 is then started, thereby driving the first gear shaft 32 and the second gear shaft 24 connected thereto to rotate, so that the cabinet door 20 rotates along its rotation axis to open the cabinet door 20.

[0103] See also Figure 4 and Figure 5 In some embodiments, the control system may further include a limiter 41. The limiter 41 may be disposed on the cabinet door 20, and the limiter 41 may be connected to the drive member 30 by signal. The limiter 41 may send a hovering signal to the drive member 30 to stop the drive member 30 from moving, so as to hover the cabinet door 20 at a preset angle.

[0104] In some embodiments, the limiting member 41 may be disposed at the bottom of the cabinet door 20 , and the limiting member 41 may protrude from the bottom end surface of the cabinet door 20 .

[0105] In some embodiments, the stopper 41 may be an angle sensor. When the cabinet door 20 is in motion, the stopper 41 can effectively sense the rotation position and angle of the cabinet door 20, so that when the cabinet door 20 reaches a preset angle, a hovering signal is immediately sent out, so that the driving member 30 stops its power output and keeps the cabinet door 20 in a hovering state at a preset angle.

[0106] In some embodiments, the stopper 41 may be a pressure sensor. When the cabinet door 20 rotates to a preset angle, the stopper 41 may abut against the cabinet body 10, so that the stopper 41 may send a hovering signal to stop the driving member 30 from working.

[0107] See also Figure 4 In some embodiments, a limit block 411 may be provided on the cabinet 10. The limit block 411 may be convexly provided on the front side of the cabinet 10, and the limit block 411 may be arranged relative to the limit member 41.

[0108] When the cabinet door 20 is gradually opened by the driving member 30 and reaches a preset angle, the limiting member 41 will gradually approach the limiting block 411 as the cabinet door 20 moves. When the cabinet door 20 reaches a specific preset angle, the limiting member 41 and the limiting block 411 on the cabinet body 10 will abut against each other, and the sensing function of the limiting member 41 will also be triggered. The limiting member 41 sends a hovering signal to the driving member 30. After receiving the hovering signal, the driving member 30 can quickly stop moving, so that the cabinet door 20 is accurately hovered at the preset opening angle.

[0109] In some embodiments, the control system may further include an infrared sensing device 42 . The infrared sensing device 42 may be disposed on the front side of the cabinet 10 ; the infrared sensor may be disposed near the power switch 16 ; and the infrared sensing device 42 may be connected to the drive member 30 for signal communication.

[0110] When the door 20 is opened, the infrared sensing device 42 will continue to monitor the area in front of the refrigerator 100. If it senses that the user is active in the area, the system will keep the door 20 open to facilitate the user to take out the items in the storage compartment 11 at any time. However, once the infrared sensing device 42 detects that the user has left, that is, it can no longer recognize the user's presence, it will immediately send a control signal to the drive member 30, and the drive member 30 will close the door 20 according to the control signal.

[0111] By providing an infrared sensor 42 to achieve automatic door closing, it is not only ensured that the refrigerator 100 can be closed in time when no one is operating, thus avoiding energy waste; it also effectively prevents the leakage of cold air caused by being open for a long time, thus ensuring the preservation of stored items; and avoiding potential losses caused by users forgetting to close the door.

[0112] See also Figure 2 In some embodiments, an electromagnetic lock 43 may be further provided on the front side of the cabinet 10. The electromagnetic lock 43 may be used to receive a locking signal from a background. The background may be a mobile terminal such as a mobile phone, a computer, or a console. The electromagnetic lock 43 may generate a magnetic force to absorb the cabinet door 20 according to the locking signal generated by the background, so as to lock the cabinet door 20.

[0113] In some embodiments, a suction portion 44 may be provided on the cabinet door 20. The suction portion 44 may be provided on the rear side of the cabinet door 20 facing the cabinet body 10, and the suction portion 44 may be provided opposite to the electromagnetic lock 43.

[0114] In some embodiments, the adsorption part 44 can be a magnetic material that can be adsorbed, such as an iron block. When the background sends a locking signal, the electromagnetic lock 43 will be immediately activated to generate a strong magnetic force. At this time, the adsorption part 44 on the cabinet door 20 will be firmly adsorbed on the front side of the cabinet body 10 by the magnetic force generated by the electromagnetic lock 43, so as to effectively lock the cabinet door 20, prevent the cabinet door 20 from being opened without authorization, and ensure the safe storage of items in the cabinet.

[0115] It is conceivable that in some other embodiments, the adsorption portion 44 may also be a magnet. When the electromagnetic lock 43 generates a positive magnetic field, the electromagnetic lock 43 can firmly adsorb the adsorption portion 44 to prevent the refrigerator 100 from being opened at will when no one is watching. When the refrigerator 100 is working normally during the day, the electromagnetic lock 43 can generate a reverse magnetic field when the user presses the control button 40 to bounce the adsorption portion 44, so that the cabinet door 20 can be opened more easily.

[0116] In summary, the present embodiment provides a cold storage cabinet 100, which includes a cabinet body 10, a cabinet door 20 and a control system. The control system includes a control button 40 and a driving member 30 electrically connected to the control button 40. The driving member 30 is fixed to the outside of the cabinet body 10 and is transmission-connected to the cabinet door 20. Therefore, the automatic opening function of the cabinet door 20 is realized without increasing the weight and volume of the cabinet door 20. The user only needs to press the control button 40 on the cabinet door 20 to easily open the cabinet door 20, and no longer needs to use a large force to overcome the negative pressure in the cabinet body 10, which greatly improves the user's convenience of use. At the same time, the driving member 30 is arranged outside the cabinet body 10, and its inspection and maintenance are also more convenient. The driving member 30 can be inspected without disassembling the cabinet door 20, which greatly simplifies the maintenance process, reduces the difficulty and cost of maintenance, and improves the use value and market prospects of the cold storage cabinet 100.
