The lock housing 31 can be disposed within the foam layer 13. The lock body 32 is disposed within the lock housing 31, so that the lock body 32 can also be arranged in the foam layer 13 along with the lock housing 31. In this way, the electronic lock 3 can be hidden in the foam layer 13, reducing the space occupied in the refrigeration chamber 10 and improving the space utilization rate inside the housing 1.

[0077] In some embodiments, a foam layer 13 may be formed between the inner wall of the housing 1 and the outer wall of the press chamber 12. That is, the foam layer 13 may be formed between the inner wall of the housing 1 and the outer wall of the housing liner 11 and the press chamber 12.

[0078] In some embodiments, a foam layer 13 may also be formed between the outer wall of the compressor chamber 12 and the outer wall of the chamber 11.

[0079] like Figure 9 and Figure 10 As shown, in some embodiments, the refrigeration equipment may include a mechanical unlocking assembly 4, which is used to release the locking member 22 and the bolt 321 from their jammed state, thereby achieving a mechanical reset of the bolt 321.

[0082] like Figure 9 and Figure 11 As shown, in some embodiments, the mechanical unlocking assembly 4 may include a link 42. One end of the link 42 may extend to the electronic lock 3 and abut against the resetter 322. When the link 42 moves toward the resetter 322 under the action of an external force, one end of the link 42 can abut against the resetter 322 to separate the locking member 22 and the bolt 321.

[0083] Figure 12 yes Figure 11 Enlarged structural diagram of region B in the middle. Figure 13 yes Figure 12 Remove the structural diagram of installation box 5 from the middle.

[0084] like Figure 9 and Figure 12 As shown, in some embodiments, the mechanical unlocking assembly 4 may include a lock cylinder mechanism 41. The lock cylinder mechanism 41 is drively connected to the end of the connecting rod 42 furthest from the resetter 322. The lock cylinder mechanism 41 is configured such that, under external force, it can drive the connecting rod 42 to move closer to the resetter 322, causing the connecting rod 42 to abut against the resetter 322, thereby separating the locking member 22 and the bolt 321. Maintenance personnel can manipulate the lock cylinder mechanism 41 to actuate the connecting rod 42, enabling the connecting rod 42 to trigger the resetter 322, thereby resetting the bolt 321, separating the locking member 22 and the bolt 321, and opening the electronic lock 3.

[0085] like Figure 3 , Figure 11 and Figure 12 As shown, in some embodiments, the lock cylinder mechanism 41 can be disposed within the foam layer 13, and one end of the lock cylinder mechanism 41 can be exposed on the inner wall of the compressor chamber 12. By concealing the main body of the lock cylinder mechanism 41 within the foam layer 13, the space occupied in the refrigeration chamber 10 is reduced, which is beneficial to improving the space utilization rate inside the housing 1. With one end of the lock cylinder mechanism 41 exposed on the inner wall of the compressor chamber 12, maintenance personnel can operate the lock cylinder mechanism 41 from the inner wall of the compressor chamber 12, thereby driving the connecting rod 42 to move, so that the connecting rod 42 can trigger the resetter 322, thereby realizing the reset of the latch 321. In addition, by concealing the exposed end of the lock cylinder mechanism 41 within the compressor chamber 12, the security of the mechanical unlocking assembly 4 can be improved, preventing it from being easily damaged or opened.

[0086] like Figure 3 As shown, in some embodiments, a front cover 14 may be provided on the front wall of the housing 1. The front cover 14 may be detachably provided on the front side of the press chamber 12, and the front cover 14 may be used to open the front side of the press chamber 12. The lock cylinder mechanism 41 may be provided on the side wall of the press chamber 12 near the front cover 14. The detachable design of the front cover 14 allows maintenance personnel to open the press chamber 12 by opening the front cover 14, and then enter the interior of the press chamber 12 to operate the lock cylinder mechanism 41.

[0087] In some embodiments, the front cover 14 may be provided with ventilation holes 141. Multiple ventilation holes 141 may be provided, and the multiple ventilation holes 141 are arranged at intervals on the front cover 14.

[0088] Figure 13 yes Figure 12 Remove the structural diagram of installation box 5 from the middle.

[0089] like Figure 3 and Figure 13 As shown in the figure, in some embodiments, a mounting box 5 may be provided inside the foam layer 13, and the mounting box 5 is fixed to the outer wall of the press chamber 12. The lock cylinder mechanism 41 may be located inside the mounting box 5. One end of the connecting rod 42 may extend into the mounting box 5 and be connected to the lock cylinder mechanism 41 for transmission. By providing the mounting box 5 inside the foam layer 13, a stable mounting space can be provided for the lock cylinder mechanism 41, so that the lock cylinder mechanism 41 and the connecting rod 42 can be connected for transmission within the mounting box 5.

[0090] like Figure 12 and Figure 13 As shown in the figure, in some embodiments, the mounting box 5 has an opening on the side facing the press chamber 12. The mounting box 5 is mounted on the outer wall of the press chamber 12 through the opening, thereby enclosing and installing the lock cylinder mechanism 41 inside the mounting box 5.

[0091] Figure 14 yes Figure 13 Structural diagram of the mechanical unlocking component 4.

[0092] like Figure 3 , Figure 13 and Figure 14 As shown, in some embodiments, the lock cylinder mechanism 41 may include a lock cylinder 411, one end of which is fixed to the side wall of the press chamber 12, and the other end of which may be disposed in the mounting box 5. The mounting box 5 provides mounting space for the lock cylinder 411, and by being disposed on the outer side wall of the press chamber 12, one end of the lock cylinder 411 may be exposed on the inner wall of the press chamber 12.

[0093] In some embodiments, the lock cylinder mechanism 41 may include a transmission rod 412. The transmission rod 412 may be disposed within the mounting box 5, with one end connected to the lock cylinder 411 and the other end connected to the connecting rod 42. The lock cylinder 411 can drive the transmission rod 412 to rotate, thereby causing the connecting rod 42 to move closer to or further away from the resetter 322. By disposing of the transmission rod 412 inside the mounting box 5, the mounting box 5 provides a stable mounting and rotation space for the transmission rod 412, thereby enabling the lock cylinder 411 to stably drive the transmission rod 412 to rotate, thereby causing the connecting rod 42 to move closer to or further away from the resetter 322. For example, when the transmission rod 412 rotates forward, it can cause the connecting rod 42 to move closer to the resetter 322, so that the connecting rod 42 abuts against the resetter 322. When the transmission rod 412 rotates in the opposite direction, the transmission rod 412 can drive the connecting rod 42 to move away from the resetter 322, so that the connecting rod 42 separates from the resetter 322.

[0094] In some embodiments, the lock cylinder 411 can drive the transmission rod 412 to rotate upward or downward. When the transmission rod 412 rotates upward, it can drive the connecting rod 42 to move upward so as to abut against the resetter 322. When the transmission rod 412 rotates downward, it can drive the connecting rod 42 to move downward so as to separate from the resetter 322.

[0095] like Figure 13 and Figure 14 As shown, in some embodiments, the end of the transmission rod 412 connected to the connecting rod 42 may be provided with a transmission hole 4121. The end of the connecting rod 42 connected to the transmission rod 412 may be provided with a bent portion, which movably passes through the transmission hole 4121. The diameter of the bent portion is smaller than the inner diameter of the transmission hole 4121, allowing the bent portion to be movably disposed within the transmission hole 4121. When the lock cylinder 411 drives the transmission rod 412 to rotate upwards, the lower edge of the transmission hole 4121 may abut against the bent portion, driving the bent portion and the connecting rod 42 to move upwards, causing the connecting rod 42 to abut against the resetter 322. When the lock cylinder 411 drives the transmission rod 412 to rotate downwards, the upper edge of the transmission hole 4121 may abut against the bent portion, driving the bent portion and the connecting rod 42 to move downwards, causing the connecting rod 42 to separate from the resetter 322.

[0096] like Figure 10 and Figure 11 As shown, in some embodiments, the connecting rod 42 can be movably disposed within the foam layer 13. The foam layer 13 provides space for the installation and movement of the connecting rod 42, reducing the space occupied within the refrigeration chamber 10 and improving the space utilization rate inside the cabinet 1.

[0097] In some embodiments, a sleeve 6 may be provided within the foam layer 13. One end of the sleeve 6 extends to the lock cylinder mechanism 41, and the other end extends to the electronic lock 3. The connecting rod 42 can be movably inserted within the sleeve 6. The sleeve 6 provides a stable installation space and movement space for the connecting rod 42, allowing the connecting rod 42 to move stably within the sleeve 6, and thus stably within the foam layer 13.

[0098] like Figure 10 and Figure 11 As shown, in some embodiments, the lock cylinder mechanism 41 can be located below the electronic lock 3, and the mounting box 5 can be located below the electronic lock 3. The sleeve 6 can extend vertically along the height direction of the housing 1. The connecting rod 42 can extend vertically along the height direction of the housing 1. By positioning the lock cylinder mechanism 41 below the electronic lock 3, the electronic lock 3 can be arranged close to the front wall and door of the housing 1, thereby allowing the lock cylinder mechanism 41 to be arranged close to the front wall and front cover 14 of the housing 1, thus facilitating the operation of the lock cylinder mechanism 41.

[0099] like Figure 10and Figure 12 As shown, in some embodiments, a through hole 51 may be provided on the top surface of the mounting box 5. The top end of the sleeve 6 may abut against the top surface of the mounting box 5, and the top end of the sleeve 6 may communicate with the interior of the mounting box 5 through the through hole 51. The lower end of the connecting rod 42 may pass through the through hole 51 and extend into the interior of the mounting box 5.

[0100] like Figure 3 and Figure 14 As shown, in some embodiments, a lock hole 4111 may be provided on the end face of the lock cylinder 411 facing the press chamber 12. The lock hole 4111 is used to insert an unlocking key, which can then drive the lock cylinder 411 to move and drive the transmission rod 412 to rotate. The lock hole 4111 and the unlocking key can easily control the lock cylinder 411, thereby driving the transmission rod 412 to rotate, preventing the lock cylinder 411 from being arbitrarily opened and manipulated, which helps to improve the security of the electronic lock 3.

[0101] like Figure 3 and Figure 14 As shown, the bottom of the lock housing 31 may be provided with a limiting port 311, which is arranged opposite to the resetter 322. The upper end of the connecting rod 42 passes through the limiting port 311, extends into the lock housing 31, and extends towards the resetter 322. The limiting port 311 can limit the upper end of the connecting rod 42, restricting the connecting rod 42 to move upward or downward within the limiting port 311, improving the stability of the movement of the connecting rod 42, and ensuring that the connecting rod 42 can contact the resetter 322.
