[0049] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0050] Combine Figures 1 to 5 As shown, an embodiment of the present disclosure provides a refrigeration device 10. The refrigeration device 10 includes a door body 11, a box body 20, a plurality of connecting rods and a driving member 12. The box body 20 defines a accommodating cavity. One end of the plurality of connecting rods is movably connected to the box body 20, and the other end of the plurality of connecting rods is respectively rotatably matched with the door body 11. The driving member 12 is provided on the door body 11, and the driving member 12 includes a driving end, which is connected to the other end of at least one connecting rod. The driving member 12 is used to drive the plurality of connecting rods to rotate relative to the door body 11, so as to drive the box body 20 to move relative to the door body 11.

[0051] In this embodiment, the box body 20 defines a receiving cavity for placing items.

[0052] In this embodiment, one end of the multiple connecting rods is movably connected to the box body 20, and the other ends of the multiple connecting rods are rotationally cooperated with the door body 11, so that the box body 20 can rotate relative to the multiple connecting rods, and the multiple connecting rods can rotate relative to the door body 11.

[0053] In this embodiment, the driving end of the driving member 12 is connected to the other end of at least one connecting rod, so that the driving member 12 drives at least one connecting rod to rotate, and then drives multiple connecting rods to rotate relative to the door body 11, so as to drive the box body 20 to move relative to the door body 11, and realize stable adjustment of the position of the box body 20 relative to the door body 11 to facilitate the taking and placing of items.

[0054] In this embodiment, the driving member 12 drives the connecting rod to rotate to drive the box body 20 to move, so that the box body 20 can be parked at different positions relative to the door body 11, which is convenient for use. Moreover, even when the box body 20 is full of items, it can still move stably, improving safety in use.

[0055] Combine Figure 1 、 Figures 3 to 5 As shown, optionally, the top of the box body 20 has a take-in and put-out opening that is connected to the accommodating cavity and is used for taking and putting items.

[0056] In this embodiment, the top of the box body 20 has an access opening that communicates with the accommodating cavity, which facilitates taking items into and out of the accommodating cavity of the box body 20. In addition, except for the access opening at the top, the bottom and surrounding areas of the box body 20 are closed structures, which can maximize the utilization of the space inside the box body 20.

[0057] In this embodiment, the top of the box body 20 has an access opening that communicates with the accommodating cavity, and one end of a plurality of connecting rods is movably connected to the box body 20. This allows the box body 20 to slightly rotate relative to one end of the connecting rods during its movement relative to the door body 11, so that the access opening of the box body 20 remains facing upward, preventing items (such as loose items or bottles) within the box body 20 from spilling, and improving the stability and safety of the items during the movement of the box body 20. Furthermore, the orientation of the access opening of the box body 20 remains unchanged during the movement, which prevents the loss of cold air flow within the box body 20 and saves energy.

[0058] It can be understood that the refrigeration equipment 10 includes but is not limited to refrigerators, freezers, etc.

[0059] Optionally, the refrigeration device 10 further includes a box body. The box body defines a storage space. A door body 11 is rotatably arranged on the box body to realize opening and closing of the door.

[0060] Combine Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the door 11 can optionally be provided with a mounting cavity on the side facing the box body, corresponding to the box body's storage space. The box body 20 is located within the mounting cavity of the door 11. Alternatively, the box body 20 is located between the mounting cavity of the door 11 and the box body's storage space. The mounting cavity of the door 11 and the box body's storage space provide space for the use and movement of the box body 20, thereby enabling smooth movement of the box body 20.

[0061] It is understood that the connection method between the driving end of the driving member 12 and the connecting rod is not limited, as long as the driving end of the driving member 12 can drive the connecting rod to rotate. For example, the driving end of the driving member 12 can be provided with a tooth groove on the inner circumference, and the outer surface of the end of the connecting rod can be provided with a tooth protrusion corresponding to the tooth groove. When in use, the end of the connecting rod is inserted into the inner side of the end of the driving end, and the protrusion cooperates with the tooth groove to enable the driving end to drive the connecting rod to rotate.

[0062] It can be understood that the driving member 12 includes but is not limited to an electric motor, etc.

[0063] For example, the driving member 12 is a stepper motor, which has high stability and can achieve smooth rotation of the box body 20 without the need for manual support during the movement of the box body 20.

[0064] Combine Figures 1 to 5As shown, in some embodiments, the plurality of connecting rods include a first connecting rod 13, a second connecting rod 14, and a third connecting rod 15. One end of the first connecting rod 13 is movably connected to the upper portion of the box body 20, and the other end of the first connecting rod 13 is rotatably engaged with the door body 11. One end of the second connecting rod 14 is movably connected to the middle portion of the box body 20, and the other end of the second connecting rod 14 is rotatably engaged with the door body 11. One end of the third connecting rod 15 is movably connected to the lower portion of the box body 20, and the other end of the third connecting rod 15 is rotatably engaged with the door body 11. The other end of at least one of the first connecting rod 13, the second connecting rod 14, and the third connecting rod 15 is connected to the driving end of the driving member 12.

[0065] In this embodiment, the first connecting rod 13, the second connecting rod 14, and the third connecting rod 15 allow the box body 20 to bypass items placed elsewhere on the door body 11 during its lifting and lowering, thereby smoothly adjusting the position of the box body 20. Even large items will not affect the movement of the box body 20, thereby improving operational reliability.

[0066] In this embodiment, one end of the first connecting rod 13 is movably connected to the upper part of the box body 20, one end of the second connecting rod 14 is movably connected to the middle part of the box body 20, and one end of the third connecting rod 15 is movably connected to the lower part of the box body 20. The first connecting rod 13, the second connecting rod 14 and the third connecting rod 15 are respectively connected to positions at different heights of the box body 20, thereby improving the stability of movement.

[0067] In this embodiment, the other end of the first connecting rod 13 is rotationally engaged with the door body 11, the other end of the second connecting rod 14 is rotationally engaged with the door body 11, and the other end of the third connecting rod 15 is rotationally engaged with the door body 11, so that the first connecting rod 13, the second connecting rod 14 and the third connecting rod 15 can all rotate relative to the door body 11.

[0068] In this embodiment, the other end of at least one of the first connecting rod 13, the second connecting rod 14 and the third connecting rod 15 is connected to the driving end of the driving member 12, so that the driving member 12 drives at least one of the first connecting rod 13, the second connecting rod 14 and the third connecting rod 15 to rotate relative to the door body 11, thereby driving the box body 20 to move.

[0069] It is understood that there is no limit to the number of driving members 12. For example, two driving members 12 may be used, both mounted on the door body 11. The driving end of one driving member 12 is connected to the first connecting rod 13, and the driving end of the other driving member 12 is connected to the third connecting rod 15. The two driving members 12 synchronously drive the first connecting rod 13 and the third connecting rod 15 to rotate relative to the door body 11, thereby achieving rotation of the first connecting rod 13, the second connecting rod 14, and the third connecting rod 15 relative to the door body 11, thereby improving the stability and safety of the movement of the box body 20.

[0070] It is understood that the connection method between the first connecting rod 13, the second connecting rod 14, and the third connecting rod 15 and the box body 20 is not limited. It is sufficient to enable the box body 20 to rotate relative to the first connecting rod 13, the second connecting rod 14, and the third connecting rod 15 so that the box body 20 always maintains the access opening facing upward during movement. For example, the box body 20 is provided with a connecting hole, and the first connecting rod 13, the second connecting rod 14, and the third connecting rod 15 are each provided with a rotating shaft corresponding to the connecting hole. The rotating shaft extends into the connecting hole to achieve rotational engagement, thereby achieving the first connecting rod 13, the second connecting rod 14, and the third connecting rod 15 being movably connected to the box body 20.

[0071] Combine Figures 1 to 5 As shown, optionally, the first connecting rod 13, the second connecting rod 14 and the third connecting rod 15 are of equal length. The distances from the connection points of the first connecting rod 13, the second connecting rod 14 and the third connecting rod 15 with the box body 20 to the door body 11 are different.

[0072] In this embodiment, the first connecting rod 13, the second connecting rod 14, and the third connecting rod 15 are of equal length. The first connecting rod 13, the second connecting rod 14, and the third connecting rod 15 are connected to the box body 20 at different vertical and front-to-back positions, so that the first connecting rod 13, the second connecting rod 14, and the third connecting rod 15 are connected to the box body 20 to form a stable three-dimensional triangular structure, thereby improving the stability of the box body 20 during movement and preventing the box body 20 from tilting or flipping.

[0073] Combine Figure 1 、 Figures 3 to 5 As shown, in some embodiments, the box body 20 includes a strip plate 21 and two end plates 22. The strip plate 21 is positioned adjacent to the door body 11. The two end plates 22 are connected to the longitudinal ends of the strip plate 21, and both end plates 22 extend away from the door body 11. One end of the first connecting rod 13 is movably connected to the upper portion of one end plate 22, one end of the second connecting rod 14 is movably connected to the middle portion of the strip plate 21, and one end of the third connecting rod 15 is movably connected to the lower portion of the other end plate 22.

[0074] In this embodiment, one end of the first connecting rod 13 is movably connected to the upper part of an end plate 22, one end of the second connecting rod 14 is movably connected to the middle part of the strip plate 21, and one end of the third connecting rod 15 is movably connected to the lower part of the other end plate 22, so that the first connecting rod 13, the second connecting rod 14 and the third connecting rod 15 are respectively connected to different positions of the box body 20 close to the door body 11, so as to stably support the box body 20 and smoothly drive the box body 20 to move.

[0075] In this embodiment, the first connecting rod 13, the second connecting rod 14 and the third connecting rod 15 are respectively connected to different sides of the box body 20, so that the moving range of the box body 20 can be increased. For example, when storing items, the box body 20 can be moved to the upper part of the door body 11, and when taking and placing items, the box body 20 can be moved to the bottom of the door body 11, which is convenient for storing and taking and placing items.

[0076] Illustratively, the first connecting rod 13 and the third connecting rod 15 are respectively connected to the two end plates 22 of the box body 20 and are respectively connected to the driving member 12, which is used to bear the rotation of the box body 20. The second connecting rod 14 is connected to the strip plate 21 of the box body 20, which can serve as an auxiliary support to prevent the box body 20 from tilting or overturning due to uneven placement of items in the storage cavity.

[0077] Optionally, the door body 11 is provided with an avoidance groove to avoid the rotation position of the second connecting rod 14 and save space.

[0078] Combine Figure 1 、 Figures 3 to 5 As shown, optionally, two strip plates 21 are provided. One strip plate 21 is positioned proximate to the door body 11, while the other strip plate 21 is positioned further away from the door body 11. The box body 20 further includes a bottom plate. The two strip plates 21 and two end plates 22 are connected to one side of the bottom plate. The two strip plates 21, the two end plates 22, and the bottom plate collectively define a receiving cavity with an access opening.

[0079] Combine Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments, the refrigeration unit 10 further includes multiple position sensors and a control device. The multiple position sensors are disposed on the door body 11 and are spaced apart along the height of the door body 11. The control device is electrically connected to the driver 12 and the multiple position sensors. The position sensors are used to detect the current position of the connecting rod and transmit this information to the control device, which can then control the operation of the driver 12 based on the current position of the connecting rod.

[0080] In this embodiment, a plurality of position sensors are provided on the door body 11 , and the plurality of position sensors are arranged at intervals along the height direction of the door body 11 for detecting the current position of the connecting rod.

[0081] In this embodiment, the position sensor can detect the current position of the connecting rod and send the current position signal of the connecting rod to the control device. The control device receives the current position signal of the connecting rod and controls the operation of the driving member 12 according to the current position of the connecting rod to adjust the position of the box body 20 relative to the door body 11.

[0082] It is understood that the type of position sensor is not limited, for example, a proximity switch, a displacement sensor, etc.

[0083] Combine Figures 1 to 5 As shown, in some embodiments, the refrigeration device 10 further includes a locking structure 30. The locking structure 30 is provided on the door body 11 and the box body 20. The locking structure 30 is electrically connected to the control device. The control device is used to control the locking and unlocking of the locking structure 30.

[0084] In this embodiment, a locking structure 30 is provided between the door body 11 and the box body 20. The locking and unlocking of the locking structure 30 is controlled by a control device to achieve the locking and unlocking of the box body 20 and the door body 11. The locking of the box body 20 and the door body 11 can improve the stability of the box body 20 installed on the door body 11.

[0085] It is understandable that the locking structure 30 is not limited, and it only needs to be able to achieve locking and unlocking of the box body 20 and the door body 11.

[0086] For example, the locking structure 30 adopts an electromagnetic lock in the prior art, which includes a lock bolt and a lock catch, and is locked and unlocked by turning on and off the power.

[0087] For another example, the locking structure 30 includes a latch 31 disposed on the door body 11 and a claw 32 disposed on the box body 20, and is locked and unlocked by pressing. In actual application, when the current position of the connecting rod is the locked position or the unlocked position, the control device can control the driving member 12 to drive the connecting rod to rotate a preset angle relative to the door body 11, driving the box body 20 to move relative to the door body 11 to realize the pressing operation, thereby achieving push-to-lock or push-to-unlock.

[0088] Combine Figures 1 to 6 As shown, the embodiment of the present disclosure also provides a control method for a refrigeration device 10, which is used to control the refrigeration device 10 as in any of the previous embodiments. The control method includes:

[0089] S601: In response to a rotation request, the processor obtains a target position of the connecting rod corresponding to the rotation request.

[0090] In this embodiment, based on the rotation request, the processor can obtain the target position of the connecting rod corresponding to the rotation request, and provide a movement end point for the movement of the connecting rod.

[0091] S602: The processor obtains the current position of the connecting rod.

[0092] In this embodiment, the current position of the connecting rod is acquired to provide a movement starting point for the movement of the connecting rod.

[0093] S603: The processor determines the target rotation direction and target rotation angle of the driving member according to the current position and the target position of the connecting rod.

[0094] In this embodiment, the target rotation direction and target rotation angle of the driving member are determined to control the connecting rod to move from the starting point to the end point.

[0095] S604: The processor controls the driving element to operate according to the target rotation direction and the target rotation angle.

[0096] In this embodiment, the processor controls the operation of the driving member 12 according to the target rotation direction and the target rotation angle to drive the connecting rod to move from the current position to the target position, that is, from the starting point of movement to the end point of movement, thereby achieving stable adjustment of the position of the box body 20, facilitating the taking and placing of items, and improving safety of use.

[0097] In this embodiment, the movement of the box body 20 is simple and quick, the time spent on opening the door is short, the loss of cooling capacity is small, and energy is saved.

[0098] Optionally, the refrigeration device 10 further includes an information input device. The information input device is disposed on the door body 11. The information input device is electrically connected to the control device. The information input device is used to send a rotation request to the control device.

[0099] In this embodiment, a rotation request is sent to the control device via the information input device, so that the control device starts to obtain the target position of the connecting rod and the current position of the connecting rod corresponding to the rotation request.

[0100] Optionally, the information input device includes but is not limited to buttons 40, a touch screen, a voice recognition device, etc.

[0101] Optionally, when the current position and target position of the connecting rod have been obtained, the control device determines the target rotation direction and target rotation angle of the driving member based on the correspondence between the current position, target position, target rotation direction and target rotation angle of the driving member 12.

[0102] For example, combined Figures 1 to 5 As shown, the operation process of the control method for the refrigeration device 10 is described by taking the information input device using a button 40, which includes a first button 41 and a second button 42, as an example.

[0103] In this example, combined with Figures 1 to 5As shown, four position sensors are provided. For the convenience of description, the four position sensors are described as a first position sensor 16, a second position sensor 17, a third position sensor 18, and a fourth position sensor 19 along the height direction of the door body 11. Among them, the position of the connecting rod detected by the first position sensor 16 corresponds to the position where the box body 20 moves to the upper part of the door body 11. The position of the connecting rod detected by the second position sensor 17 and the third position sensor 18 corresponds to the position where the box body 20 moves to the middle part of the door body 11. The position of the connecting rod detected by the fourth position sensor 19 corresponds to the position where the box body 20 moves to the lower part of the door body 11. In this example, the first position sensor 16, the second position sensor 17, the third position sensor 18, and the fourth position sensor 19 all use proximity switches.

[0104] In this example, the corresponding relationship among the current position of the connecting rod, the target position, the target rotation direction of the driving member 12, and the target rotation angle is shown in Table 1.

[0107] In this example, as shown in Table 1, the user presses first button 41 once, sending a rotation request to the processor. The processor receives the rotation request, determines that the target position is at the second position sensor 17 and the current position of the connecting rod is at the first position sensor 16, and determines the target rotation direction of the driving member 12 to be the first direction and the target rotation angle α. Based on the target rotation direction being the first direction and the target rotation angle α, the processor controls the driving member 12 to move the connecting rod from the first position sensor 16 to the second position sensor 17.

[0108] In this example, as shown in Table 1, the user presses first button 41 once, sending a rotation request to the processor. The processor receives the rotation request, determines that the target position is at the third position sensor 18 and the current position of the connecting rod is at the second position sensor 17, and determines the target rotation direction of the driving member 12 to be the first direction and the target rotation angle α. Based on the target rotation direction being the first direction and the target rotation angle α, the processor controls the driving member 12 to move the connecting rod from the second position sensor 17 to the third position sensor 18.

[0109] In this example, as shown in Table 1, the user presses second button 42 once, sending a rotation request to the processor. The processor receives the rotation request, determines that the target position is at the second position sensor 17 and the current position of the connecting rod is at the third position sensor 18, and determines the target rotation direction of the driving member 12 to be the second direction and the target rotation angle α. Based on the target rotation direction being the second direction and the target rotation angle α, the processor controls the driving member 12 to move the connecting rod from the third position sensor 18 to the second position sensor 17.

[0110] In this example, as shown in Table 1, the user presses second button 42 once, sending a rotation request to the processor. The processor receives the rotation request, determines that the target position is at the third position sensor 18, the current position of the connecting rod is at the fourth position sensor 19, and determines that the target rotation direction of the driving member 12 is the second direction and the target rotation angle is α. Based on the target rotation direction being the second direction and the target rotation angle being α, the processor controls the operation of the driving member 12 to move the connecting rod from the fourth position sensor 19 to the third position sensor 18.

[0111] In this example, as shown in Table 1, the user continuously presses (for example, pressing the button for more than 3 seconds is considered continuous pressing) the first button 41 to send a rotation request to the processor. The processor receives the rotation request, obtains the target position as the fourth position sensor 19, the current position of the connecting rod as the first position sensor 16, and determines that the target rotation direction of the driving member 12 is the first direction and the target rotation angle is 3α. The processor controls the operation of the driving member 12 based on the target rotation direction being the first direction and the target rotation angle being 3α, so as to drive the connecting rod to move from the first position sensor 16 to the fourth position sensor 19. In other words, by continuously pressing the first button 41, a rotation request can be sent to the control device to move the box body 20 directly from the upper or middle part of the door body 11 to the lower part of the door body 11.

[0112] In this example, as shown in Table 1, the user continuously presses first button 41, sending a rotation request to the processor. The processor receives the rotation request, determines that the target position is at the fourth position sensor 19, the current position of the connecting rod is at the second position sensor 17, and determines that the target rotation direction of the driving member 12 is the first direction and the target rotation angle is 2α. Based on the target rotation direction being the first direction and the target rotation angle being 2α, the processor controls the operation of the driving member 12 to drive the connecting rod from the second position sensor 17 to the fourth position sensor 19.

[0113] In this example, as shown in Table 1, the user continuously presses the second button 42 to send a rotation request to the processor. The processor receives the rotation request, determines that the target position is at the first position sensor 16 and the current position of the connecting rod is at the third position sensor 18, and determines that the target rotation direction of the driving member 12 is the second direction and the target rotation angle is 2α. Based on the target rotation direction being the second direction and the target rotation angle being 2α, the processor controls the operation of the driving member 12 to drive the connecting rod from the third position sensor 18 to the first position sensor 16. In other words, by continuously pressing the second button 42, a rotation request is sent to the control device to move the box body 20 directly from the lower or middle portion of the door body 11 to the upper portion of the door body 11.

[0114] In this example, as shown in Table 1, the user continuously presses second button 42, sending a rotation request to the processor. The processor receives the rotation request, determines that the target position is at first position sensor 16 and the current position of the connecting rod is at fourth position sensor 19, and determines that the target rotation direction of the driving member 12 is the second direction and the target rotation angle is 3α. Based on the second target rotation direction and the target rotation angle of 3α, the processor controls the driving member 12 to move the connecting rod from the fourth position sensor 19 to the first position sensor 16.

[0115] In this example, the first direction and the second direction are opposite to each other. For example, the first direction is a direction for driving the box body 20 to move downward, and the second direction is a direction for driving the box body 20 to move upward.

[0116] Optionally, the current position and the target position of the connecting rod are not the same position.

[0117] Optionally, the refrigeration unit 10 further includes an alarm device. The alarm device is disposed on the door body 11 and is electrically connected to the control device. When the rotation request indicates that the current position of the connecting rod and the target position are the same, the control device controls the driving member 12 to remain inactive and controls the alarm device to sound an alarm.

[0118] For example, a user presses first button 41 once, sending a rotation request to the processor. The processor receives the rotation request and obtains the target position as the position at fourth position sensor 19 and the current position of the connecting rod as the position at fourth position sensor 19. The control device stops the driving member 12 from operating and controls the alarm device to sound an alarm.

[0119] It is understood that the alarm device is not limited and can include, for example, a buzzer, a voice reminder device, etc.

[0120] In some embodiments, the step of controlling the driving member 12 to operate according to the target rotation direction and the target rotation angle includes: controlling the driving member 12 to rotate along the target rotation direction by the target rotation angle according to the target rotation direction and the target rotation angle.

[0121] In this embodiment, the driving member 12 is controlled to rotate along the target rotation direction by the target rotation angle so that the connecting rod can move from the current position to the target position, thereby achieving the adjustment of the position of the box body 20.

[0122] Combine Figures 1 to 5 as well as Figure 7 As shown, in some embodiments, the refrigeration device 10 includes a locking structure 30 , and before the step of controlling the operation of the driving member 12 according to the target rotation direction and the target rotation angle, the step further includes: controlling the locking structure 30 to unlock.

[0123] Combine Figure 7 As shown, in this embodiment, the control method includes:

[0124] S701: In response to a rotation request, the processor obtains a target position of the connecting rod corresponding to the rotation request.

[0125] S702: The processor obtains the current position of the connecting rod.

[0126] S703: The processor determines the target rotation direction and target rotation angle of the driving member according to the current position and the target position of the connecting rod.

[0127] S704: The processor controls the locking structure to unlock.

[0128] S705: The processor controls the driving element to operate according to the target rotation direction and the target rotation angle.

[0129] In this embodiment, before the step of controlling the driving member to operate according to the target rotation direction and the target rotation angle, the locking structure 30 is controlled to be unlocked so that the driving member 12 can smoothly drive the connecting rod to move.

[0130] Combine Figures 1 to 5 as well as Figure 8 As shown, in some embodiments, after the step of controlling the operation of the driving member 12 according to the target rotation direction and the target rotation angle, the method further includes: controlling the locking structure 30 to lock when the connecting rod rotates to the target position.

[0131] Combine Figure 8 As shown, in this embodiment, the control method includes:

[0132] S801: In response to a rotation request, the processor obtains a target position of the connecting rod corresponding to the rotation request.

[0133] S802: The processor obtains the current position of the connecting rod.

[0134] S803: The processor determines the target rotation direction and target rotation angle of the driving member according to the current position and the target position of the connecting rod.

[0135] S804: The processor controls the driving element to operate according to the target rotation direction and the target rotation angle.

[0136] S805: When the connecting rod rotates to the target position, the processor controls the locking structure to lock.

[0137] In this embodiment, when the connecting rod is rotated to the target position, the locking structure 30 is controlled to lock, so that the box body 20 and the door body 11 are locked, thereby improving the stability of the box body 20.

[0138] Combine Figures 1 to 5 as well as Figure 9 As shown, in some embodiments, the control method includes:

[0139] S901: In response to a rotation request, the processor obtains a target position of the connecting rod corresponding to the rotation request.

[0140] S902: The processor obtains the current position of the connecting rod.

[0141] S903: The processor determines the target rotation direction and target rotation angle of the driving member according to the current position and the target position of the connecting rod.

[0142] S904: The processor controls the locking structure to unlock.

[0143] S905: The processor controls the driving element to operate according to the target rotation direction and the target rotation angle.

[0144] S906: When the connecting rod rotates to the target position, the processor controls the locking structure to lock.

[0145] In this embodiment, the locking structure 30 is unlocked so that the driving member 12 can smoothly drive the connecting rod to move. By controlling the locking structure 30 to lock, the box body 20 and the door body 11 are locked, thereby improving the stability of the box body 20.

[0146] For example, taking the case where four position sensors are provided, for ease of description, the four position sensors are described as a first position sensor 16, a second position sensor 17, a third position sensor 18, and a fourth position sensor 19 along the height direction of the door body 11. The position of the connecting rod detected by the first position sensor 16 corresponds to the movement of the box body 20 to the upper part of the door body 11. The position of the connecting rod detected by the second position sensor 17 and the third position sensor 18 corresponds to the movement of the box body 20 to the middle part of the door body 11. The position of the connecting rod detected by the fourth position sensor 19 corresponds to the movement of the box body 20 to the lower part of the door body 11.

[0147] In this example, locking structures 30 are provided at both the upper and lower portions of the door body 11. That is, when the connecting rod moves to the first position sensor 16 and the fourth position sensor 19, the locking structure 30 is locked. For example, when the control device controls the driving member 12 to drive the connecting rod to move to the first position sensor 16, the locking structure 30 is controlled to lock, so that the box body 20 is locked to the door body 11. For another example, when the current position of the connecting rod is at the fourth position sensor 19, the control device controls the locking structure 30 to unlock (i.e., unlock the box body 20 from the door body 11), and then controls the driving member 12 to operate according to the target rotation direction and target rotation angle.

[0148] Exemplarily, the locking structure 30 includes a buckle 31 provided on the door body 11 and a claw 32 provided on the box body 20. The specific method of locking and unlocking by pressing is as follows. When the target position of the connecting rod is at the first position sensor 16, the driving member 12 rotates in the second direction to drive the connecting rod to move to the first position sensor 16 (i.e., the locked position), and the control device controls the driving member 12 to continue to rotate in the second direction by a preset angle to drive the connecting rod to rotate relative to the door body 11, thereby realizing the pressing operation of the box body 20 on the door body 11, that is, realizing the press-locking of the box body 20 and the door body 11. When the current position of the connecting rod is at the fourth position sensor 19 (i.e., the unlocked position) and the target position is at the third position sensor 18, the control device controls the driving member 12 to rotate in the first direction by a preset angle to drive the connecting rod to rotate relative to the door body 11, thereby realizing the pressing operation of the box body 20 on the door body 11, i.e., realizing the pressing and unlocking of the box body 20 and the door body 11, and then controlling the driving member 12 to rotate in the second direction to the third position sensor 18.

[0149] Combine Figures 1 to 5 as well as Figure 10 As shown, in some embodiments, the refrigeration device 10 includes a control device and a power storage device electrically connected to the control device, and the power storage device is used to supply power to the control device when the refrigeration device 10 is powered off. The control method includes:

[0150] S1001: When the refrigeration equipment is powered off, the processor determines the current position of the connecting rod.

[0151] S1002: The processor determines the safe rotation direction and safe rotation angle of the driving member according to the current position of the connecting rod.

[0152] S1003: The processor controls the driving member to rotate along the safe rotation direction by the safe rotation angle according to the safe rotation direction and the safe rotation angle.

[0153] In this embodiment, when the refrigeration unit 10 is powered off, the processor determines the current position of the connecting rod, providing a starting point for controlling the movement of the connecting rod. Based on the current position of the connecting rod, the processor determines the safe rotation direction and safe rotation angle of the driver 12, providing parameters for the rotation of the driver 12. Based on the safe rotation direction and safe rotation angle, the driver 12 is controlled to rotate in the safe rotation direction by the safe rotation angle to move the connecting rod to a safe position, that is, to move the housing 20 to a safe position (e.g., below the door), thereby improving the safety of the refrigeration unit 10 when it is powered off.

[0154] Optionally, the processor determines the safe rotation direction and safe rotation angle of the driving member 12 according to the current position of the connecting rod and the corresponding relationship between the current position of the connecting rod, the safe rotation direction and the safe rotation angle of the driving member 12.

[0155] For example, the safe position is taken as the fourth position sensor 19. Table 2 shows the corresponding relationship between the current position of the connecting rod, the safe rotation direction and the safe rotation angle of the driving member 12.

[0156] Table 2

[0157] Current location Safe rotation direction Safe rotation angle safe location First position sensor First direction 3α Fourth position sensor The second position sensor First direction 2α Fourth position sensor The third position sensor First direction α Fourth position sensor

[0158] In this example, as shown in Table 1, when the refrigeration equipment 10 is powered off and the processor determines that the current position of the connecting rod is at the first position sensor 16, the safe rotation direction of the driving member 12 is determined to be the first direction, the safe rotation angle is 3α, and the driving member 12 is controlled to operate so that the connecting rod moves to the fourth position sensor 19 (safe position).

[0159] In this example, as shown in Table 1, when the refrigeration equipment 10 is powered off and the processor determines that the current position of the connecting rod is at the second position sensor 17, the safe rotation direction of the driving member 12 is determined to be the first direction, the safe rotation angle is 2α, and the driving member 12 is controlled to operate so that the connecting rod moves to the fourth position sensor 19 (safe position).

[0160] In this example, as shown in Table 1, when the refrigeration equipment 10 is powered off and the processor determines that the current position of the connecting rod is at the third position sensor 18, the safe rotation direction of the driving member 12 is determined to be the first direction, the safe rotation angle is α, and the driving member 12 is controlled to operate so that the connecting rod moves to the fourth position sensor 19 (safe position).
