[0049] Combination Figures 1 to 10As shown, the embodiment of the present disclosure provides a door body assembly for a refrigeration device, and the door body assembly for the refrigeration device includes a first door body 10, a plurality of second door bodies 20, a rotating shaft 30 and a plurality of clutch mechanisms 40. The first door body 10 defines a plurality of accommodating chambers 101 with openings; the plurality of second door bodies 20 are arranged in a one-to-one correspondence with the plurality of accommodating chambers 101, and the plurality of second door bodies 20 can be movably covered at the openings of the corresponding accommodating chambers 101; the rotating shaft 30 is rotatably connected to the first door body 10 and the plurality of second door bodies 20, and the plurality of second door bodies 20 rotate relative to the first door body 10 around the rotating shaft 30 to open or close the accommodating chambers 101 corresponding to the second door bodies 20; the number of clutch mechanisms 40 is the same as the number of second door bodies 20, and the clutch mechanisms 40 are arranged in a one-to-one correspondence with the second door bodies 20, and the plurality of clutch mechanisms 40 can be connected or disconnected with the rotating shaft 30 in a controllable manner. When the clutch mechanism 40 is connected to the rotating shaft 30, the second door body 20 corresponding to the clutch mechanism 40 can rotate under the drive of the rotating shaft 30.

[0050] According to the embodiment of the present disclosure, by defining a plurality of accommodating cavities 101 with openings in the first door body 10, the plurality of accommodating cavities 101 are independent of each other, and the odor of the items in different accommodating cavities 101 can be avoided. By providing a plurality of second door bodies 20 and arranging the plurality of second door bodies 20 in one-to-one correspondence with the plurality of accommodating cavities 101, and the plurality of second door bodies 20 can be movably covered at the openings of the corresponding accommodating cavities 101, the plurality of second door bodies 20 can be closed or opened, and when the second door bodies 20 are closed, the accommodating cavities 101 corresponding to the second door bodies 20 form a closed space, thereby ensuring the airtightness of the accommodating cavities 101. By providing a rotating shaft 30 and rotatably connecting the rotating shaft 30 with the first door body 10 and the plurality of second door bodies 20, the plurality of second door bodies 20 can be rotated relative to the first door body 10 around the rotating shaft 30, so that the corresponding accommodating cavities 101 are opened or closed by the second door bodies 20. By setting a plurality of clutch mechanisms 40, and setting the number of clutch mechanisms 40 to be the same as the number of second door bodies 20 and corresponding to each other, each second door body 20 can have a corresponding clutch mechanism 40. By setting the plurality of clutch mechanisms 40 to be controllably connected or disconnected with the rotating shaft 30, that is, the plurality of clutch mechanisms 40 can be connected with the rotating shaft 30, and the connection structure 81 between the clutch mechanism 40 and the rotating shaft 30 can be movable relative to the rotating shaft 30, so that the clutch mechanism 40 is connected with the rotating shaft 30 or disconnected. When the clutch mechanism 40 is connected with the rotating shaft 30, the second door body 20 corresponding to the clutch mechanism 40 can be rotated under the drive of the rotating shaft 30, so that the second door body 20 opens or closes the corresponding accommodating cavity 101. In this way, when the user needs to open a plurality of second door bodies 20 at the same time, the clutch mechanism 40 of the second door body 20 to be opened can be connected with the rotating shaft 30, so that the plurality of second door bodies 20 can be opened or closed at one time, which can improve the convenience of the user.

[0051] Specifically, during actual use, the user can manually open one of the multiple second door bodies 20 that need to be opened, and use the rotating shaft 30 and the clutch mechanism 40 to drive the other second door bodies 20 that need to be opened to open, thereby improving user convenience.

[0052] Optionally, the clutch mechanism 40 includes: a connecting member 41 and a limiting member 42, the connecting member 41 is sleeved on the rotating shaft 30; the limiting member 42 can be movably arranged in the second door body 20, and one end of the limiting member 42 can be connected to or disconnected from the connecting member 41; wherein, the limiting member 42 can move between a first position and a second position, when the limiting member 42 is in the first position, the limiting member 42 is connected to the connecting member 41, and the rotating shaft 30 can drive the limiting member 42 to rotate; when the limiting member 42 is in the second position, the limiting member 42 is disconnected from the connecting member 41.

[0053] By adopting the embodiment of the disclosure, the connecting member 41 and the stopper 42 are provided, and the rotating shaft 30 and the connecting member 41 move coaxially. When the stopper 42 is connected to the connecting member 41, the rotating shaft 30 can drive the connecting member 41 to rotate, and the connecting member 41 drives the stopper 42 to move. The stopper 42 can transmit the force to the second door body 20, so that the rotating shaft 30 drives the second door body 20 to rotate. In addition, by providing the stopper 42, the contact area between the rotating shaft 30 and the second door body 20 can be increased, and the force arm of the rotating shaft 30 on the second door body 20 can be extended. Compared with the method of only providing the rotating shaft 30 to drive the second door body 20, this embodiment requires less driving force when driving the second door body 20 to rotate, which can improve the convenience of opening the door.

[0054] Specifically, the connecting member 41 can be a gear or a block, and the connection between the limiting member 42 and the connecting member 41 can also be adaptively changed according to the structural form of the connecting member 41. It can be understood that the specific structural form of the connecting member 41 and the connecting end of the limiting member 42 and the connecting member 41 is not unique.

[0055] Optionally, combined Figure 3 and Figure 4 As shown in , the connecting member 41 is a gear structure, and the connecting end of the limiting member 42 and the connecting member 41 is arranged on a connecting gear adapted to the gear structure, and the connecting gear is meshed with the gear structure.

[0056] In this way, the position limiting member 42 can be connected to the connecting member 41 at multiple positions, thereby improving the convenience of connection. In actual use, after the user opens one or more of the multiple second door bodies 20 to a certain angle, if the user still wants to open the unopened second door body 20 among the multiple second door bodies 20, the position limiting member 42 corresponding to the unopened second door body 20 can be moved to the first position connected to the connecting member 41, and the second door body 20 can be continued to be opened, so that the unopened second door body 20 can also be opened together with the previous second door body 20. The multiple second door bodies 20 are opened at different angles, thereby improving the convenience of user use.

[0057] Optionally, the clutch mechanism 40 further includes: a driving motor, which is drivingly connected to the limiting member 42 , and is used to drive the limiting member 42 to move between the first position and the second position.

[0058] In this way, the limit member 42 can be automatically moved between the first position and the second position by sending a control instruction to the drive motor, thereby improving the automation level of the door assembly for the refrigeration equipment.

[0059] Optionally, the connecting member 41 is sleeved on the rotating shaft 30 and is movably connected to the rotating shaft 30. The connecting member 41 can be controlled to move relative to the rotating shaft 30 along the extension direction of the rotating shaft 30. The limiting member 42 is fixed to the second door body 20, and one end of the limiting member 42 can be connected to the connecting member 41 so that the connecting member 41 drives the limiting member 42 to move.

[0060] Specifically, the connecting member 41 can move along the extension direction of the rotating shaft 30, and the connecting member 41 has a third position and a fourth position. When the connecting member 41 is in the third position, the connecting member 41 is connected to the limiting member 42, and the rotating shaft 30 drives the second door body 20 to move through the connecting member 41 and the limiting member 42; when the connecting member 41 is in the fourth position, the connecting member 41 is connected and disconnected from the limiting member 42.

[0061] It can be understood that the specific structural form of the clutch mechanism 40 is not unique, and any specific structural form that can controllably connect or disconnect the clutch mechanism 40 and the rotating shaft 30 belongs to one of the optional implementations of the present application.

[0062] Optionally, the limiting member 42 is provided with a shifting portion 421, which extends from the first door body 10 toward the second door body 20; wherein the second door body 20 is provided with an opening, the opening is arranged corresponding to the shifting portion 421, and a portion of the shifting portion 421 passes through the opening and is exposed to the second door body 20, so that the limiting member 42 can move between the first position and the second position through the movable shifting portion 421.

[0063] By adopting the embodiment of the present disclosure, a shift lever portion 421 is provided on the limit member 42, and the shift lever portion 421 can be exposed to the second door body 20 through an opening on the second door body 20. The user can manually control the position of the shift lever portion 421, and then control the position of the limit member 42, so that the user can freely select the second door body 20 to be opened according to his or her own usage needs.

[0064] Optionally, the clutch mechanism 40 further includes: a fixed seat 43 and a limit block 44, wherein the fixed seat 43 is disposed on the second door body 20 and is located on one side of the shifting portion 421; the limit block 44 is movably connected to the fixed seat 43, and the limit block 44 can abut against the shifting portion 421 to limit the position of the shifting portion 421. The limit block 44 has an initial position and a compressed position and can move between the initial position and the compressed position. When the limit block 44 is in the initial position, the limit block 44 abuts against the shifting portion 421 to limit the position of the shifting portion 421; when the limit block 44 is in the compressed position, the shifting portion 421 can move relative to the limit block 44.

[0065] According to the embodiment of the present disclosure, by providing the fixing seat 43 and the limiting block 44, the limiting block 44 can fix the position of the shifting portion 421 by contacting with the shifting portion 421, thereby fixing the position of the limiting member 42, so that the limiting member 42 is stably located at the first position or the second position. The shifting portion 421 can move relative to the limiting block 44, that is, the shifting portion 421 does not contact the limiting block 44, the limiting block 44 cannot limit the position of the shifting portion 421, and the shifting portion 421 can fall freely under the action of gravity, or move upward under the action of an external force.

[0066] Exemplary, combined Figure 6 As shown in , the limit block 44 can move relative to the connecting member 41 in the up-down direction. Since the shifting part 421 is arranged on the limit block 44, the first position and the second position of the shifting part 421 are respectively the uppermost and lowermost positions that the shifting part 421 can move, wherein the position of the shifting part 421 at the uppermost end is defined as the first position, and the position of the shifting part 421 at the lowermost end is defined as the second position. The first position and the second position are arranged in the up-down direction, the fixing seat 43 and the limit block 44 are arranged on one side of the left and right sides of the shifting part 421, the limit block 44 can move relative to the fixing seat 43 in the left-right direction, and when the limit block 44 is in the initial position, the limit block 44 abuts against the shifting part 421, and the limit block 44 can fix the position of the shifting part 421 at the first position or the second position to prevent the shifting part 421 from freely moving in the up-down direction. When the limit block 44 is in the compressed position, the limit block 44 is not in contact with the shifting portion 421, and the limit block 44 cannot limit the position of the shifting portion 421. The shifting portion 421 can freely fall to the second position under the action of external force, or move upward to the first position under the action of external force.

[0067] It should be noted that the limit member 42 can also move in the left and right direction relative to the connecting member 41 to connect or disconnect the limit member 42 with the connecting member 41. It can be understood that the first position and the second position of the limit member 42 include but are not limited to the situation in which they are set in the up and down directions in this embodiment.

[0068] Optionally, the clutch mechanism 40 further includes an elastic member 45 , which is disposed between the limit block 44 and the fixing seat 43 and is used to make the limit block 44 automatically rebound to an initial position.

[0069] According to the embodiment of the present disclosure, by providing an elastic member 45 and arranging the elastic member 45 between the limit block 44 and the fixed seat 43, when the limit block 44 is subjected to an external force, the elastic member 45 will be squeezed to make the limit block 44 move toward the fixed seat 43, thereby releasing the limit block 44 from limiting the limit member 42. When the limit member 42 is not subjected to an external force or the external force applied is not sufficient to cause the elastic member 45 to undergo elastic deformation, the limit member 42 will be in the initial position. In this way, the limit block 44 can automatically rebound to the initial position, avoiding the situation that when the limit member 42 moves from the second position to the first position, the limit block 44 cannot move to the initial position in time, causing the limit member 42 to fall back to the second position under the action of gravity. It can also avoid the situation that when the shifting portion 421 is accidentally touched, the limit member 42 moves from the first position to the second position, thereby ensuring the limiting effect of the limit block 44 on the limit member 42.

[0070] Specifically, the elastic member 45 may be a spring or a rubber member. It is understandable that the specific form of the elastic member 45 is not unique.

[0071] Preferably, combined Figure 6 As shown in FIG. 4 , the elastic member 45 is a spring, which is sleeved on the limiting block 44 and located between the limiting block 44 and the fixing seat 43 .

[0072] Optionally, the number of the fixing seats 43 and the number of the limiting blocks 44 are both two, and the two fixing seats 43 and the two limiting blocks 44 are arranged opposite to each other and located on both sides of the shifting portion 421 .

[0073] By adopting the embodiment of the present disclosure, by arranging two fixing seats 43 and two limit blocks 44 relatively to each other and being located on both sides of the shifting portion 421, the two limit blocks 44 can abut against the shifting portion 421, which can evenly distribute the force on the shifting portion 421, and then can stably support the shifting portion 421, thereby improving the reliability of the door body assembly for refrigeration equipment.

[0074] Optionally, a guide structure 441 is provided at one end of the limiting block 44 facing the shifting portion 421 , and a guide portion 4211 matched with the guide structure 441 is provided at an end surface of the shifting portion 421 facing the limiting block 44 .

[0075] According to the embodiment of the present disclosure, a guide structure 441 is provided at one end of the limit block 44 facing the shifting part 421, and a guide part 4211 matching the guide structure 441 is provided at the end surface of the shifting part 421 facing the limit block 44. The guide structure 441 cooperates with the guide part 4211 to reduce the resistance of the shifting part 421 to the movement between the first position and the second position and the movement of the limit block 44, thereby improving the convenience of the movement of the shifting part 421. In this way, there is no need to separately provide a position control structure for the limit member 42. By changing the magnitude of the force applied to the shifting part 421, when the force transmitted from the shifting part 421 to the limit block 44 is greater than the threshold value of the elastic deformation of the elastic member 45, the limit block 44 can be moved from the initial position to the compressed position, which can facilitate the user to adjust the position of the shifting part 421 while reducing the structural complexity and cost of the door assembly for the refrigeration equipment.

[0076] Specifically, combined Figure 6 As shown in the figure, the shifting part 421 is inclined at both ends toward the end of the limit block 44, and the two ends of the end surface of the limit block 44 facing the shifting part 421 are arranged as inclined surfaces adapted to the inclined surface of the shifting part 421. In this way, when the limit member 42 is in the first position, the guide structure 441 of the limit block 44 abuts against the guide part 4211 of the shifting part 421, and the limit block 44 can provide sufficient support force for the shifting part 421, and by being arranged in the form of an inclined surface, the movement resistance of the shifting part 421 can be effectively reduced.

[0077] Exemplary, combined Figure 6 As shown in , the upper and lower ends of the limit block 44 facing the shifting portion 421 are both provided with guide structures 441 . Similarly, the upper and lower ends of the shifting portion 421 are also both provided with guide portions 4211 matched with the guide structures 441 .

[0078] In this way, the limiting block 44 can conveniently limit the position of the shifting portion 421 and can also facilitate the shifting portion 421 to move relative to the limiting block 44 .

[0079] It should be noted that the guide structure 441 and the guide portion 4211 may also be configured to be arc-shaped, and the specific structural forms of the guide structure 441 and the guide portion 4211 include but are not limited to the structures shown in the figure.

[0081] According to the embodiment of the present disclosure, a driving device 50 is provided and is drivably connected to the rotating shaft 30. When the driving device 50 is in operation, the rotating shaft 30 can be driven to rotate. The rotating shaft 30 can drive the second door body 20 to rotate relative to the first door body 10, so that the second door body 20 is rotated to a position to open the accommodating cavity 101 or a position to close the accommodating cavity 101, so that the second door body 20 is automatically opened or closed.

[0082] Optionally, the driving device 50 includes: a motor, a first transmission gear 52, a second transmission gear 53 and a third transmission gear 54, the motor is arranged on the first door body 10 or is suitable for being arranged on a refrigeration device; the first transmission gear 52 is arranged on the first door body 10 and connected to the motor; the second transmission gear 53 is arranged on the first door body 10 and connected to the first transmission gear 52; the third transmission gear 54 is sleeved on the rotating shaft 30 and connected to the second transmission gear 53; wherein the motor is drivingly connected to the rotating shaft 30, and the motor can drive the rotating shaft 30 to rotate forward or reversely to open or close the second door body 20.

[0083] According to the embodiment of the present disclosure, by setting a motor and driving the motor to connect the rotating shaft 30, the motor can be controlled to rotate forward or reverse, thereby controlling the rotating shaft 30 to drive the second door body 20 to open or close the accommodating chamber 101. By setting the first transmission gear 52, the second transmission gear 53 and the third transmission gear 54, the motor can drive the first transmission gear 52 to rotate, the first transmission gear 52 can drive the second transmission gear 53 to rotate, and the second transmission gear 53 drives the third transmission gear 54 to rotate. By sleeved on the rotating shaft 30, the rotating shaft 30 and the third transmission gear 54 can be rotated synchronously. By controlling the direction and rotation angle of the third transmission gear 54, the direction and rotation angle of the rotating shaft 30 can be controlled, thereby controlling the movement of the second door body 20. This embodiment uses gear transmission, with high transmission accuracy, and can accurately control the angle that the rotating shaft 30 needs to rotate, so as to accurately open or close the second door body 20.

[0084] It should be noted that the setting position of the motor is not unique, and the position of the motor can be flexibly adjusted according to actual use.

[0085] Optionally, a sealing strip is provided at the connection between the second door body 20 and the first door body 10 .

[0086] In this way, the sealing effect between the second door body 20 and the first door body 10 can be ensured.

[0087] Optionally, the driving device 50 further includes a gear commutator, which is connected to both the motor and the rotating shaft 30 and is used to change the rotation direction of the rotating shaft 30 .

[0088] In this way, the forward and reverse rotations of the rotating shaft 30 can be controlled without adjusting the rotation direction of the motor.

[0089] It should be noted that the structure of the driving device 50 is not unique, and any structure that can drive the rotating shaft 30 to rotate forward and reverse is one of the optional implementations of the present application.

[0090] Optionally, the number of teeth of the first transmission gear 52 is smaller than the number of teeth of the second transmission gear 53 , and / or the number of teeth of the second transmission gear 53 is smaller than the number of teeth of the third transmission gear 54 .

[0091] According to the embodiment of the present disclosure, by setting the number of teeth of the first transmission gear 52 smaller than the number of teeth of the second transmission gear 53, the first transmission gear 52 rotates one circle while the second transmission gear 53 rotates less than one circle, so that the transmission ratio can be greater than 1, thereby preventing the second door body 20 from opening or closing too quickly. By setting the number of teeth of the second transmission gear 53 smaller than the number of teeth of the third transmission gear 54, the second transmission gear 53 rotates one circle while the third transmission gear 54 rotates less than one circle, so that the transmission ratio can be greater than 1, thereby making the rotation angle of the rotating shaft 30 smaller, thereby preventing the second door body 20 driven by the rotating shaft 30 from opening or closing too quickly.

[0092] Preferably, the transmission ratio of the first transmission gear 52 to the second transmission gear 53 is 5:1.

[0093] By adopting the embodiment of the present disclosure, by forming an avoidance portion 201 at the end of the second door body 20 rotating around the rotation axis 30, the second door body 20 can avoid interference with the first door body 10 when rotating around the rotation axis 30, thereby affecting the opening or closing of the second door body 20.

[0094] Optionally, the end of the first door body 10 where the rotating shaft 30 is disposed is recessed along the direction of the second door body 20 toward the first door body 10 .

[0095] In this way, when the second door body 20 rotates around the first door body 10, the first door body 10 can avoid the rotating end of the second door body 20, so as to avoid the interference between the second door body 20 and the first door body 10 when the second door body 20 rotates.

[0096] Exemplary, combined Figure 2 As shown in the figure, the end of the second door body 20 rotating around the rotating axis 30, that is, the right end of the second door body 20, the side wall of the second door body 20 close to the first door body 10 is arc-shaped, and the side wall of the right end of the first door body 10 is recessed in the direction away from the second door body 20.

[0097] Optionally, a first sealing plate 11 is provided on the end surface of the first door body 10 facing the second door body 20, and a second sealing plate 21 is provided on the end surface of the second door body 20 facing the first door body 10, and the second sealing plate 21 is provided corresponding to the first sealing plate 11; wherein, when the second door body 20 covers the accommodating cavity 101, the first sealing plate 11 abuts against the second sealing plate 21.

[0098] By adopting the embodiment of the present disclosure, by providing the first sealing plate 11 and the second sealing plate 21, the sealing effect of the second door body 20 when closing the opening of the accommodating cavity 101 can be ensured, and the cold energy in the accommodating cavity 101 can be prevented from flowing out through the avoidance portion 201 or the recessed portion of the first door body 10 to affect the sealing effect of the accommodating cavity 101.

[0099] Optionally, the door body assembly for refrigeration equipment also includes: a detection device, which is arranged on the second door body 20 or the first door body 10, and is used to detect user information and send door opening signals and door closing signals; wherein, the driving device 50 is electrically connected to the detection device, and the driving device 50 is configured to receive the signal of the detection device and control the operation of the driving device 50 according to the signal of the detection device.

[0100] By adopting the embodiment of the present disclosure, a detection device is set up and electrically connected to the driving device 50, so that the detection device can detect the user's information, such as the user's body temperature, the user's voice, etc. in real time, and judge whether the user needs to open or close the door based on the detected user information so as to send the door opening signal and the door closing signal to the driving device 50 in real time. The driving device 50 works according to the received door opening signal or door closing signal to open or close the second door body 20.

[0101] Specifically, the detection device can be an infrared sensor. When the infrared sensor detects that a human body is approaching, the infrared sensor sends a door opening signal to the driving device 50, and the driving device 50 drives the rotating shaft 30 to rotate to open the second door body 20; when the infrared sensor detects that the human body has left, the infrared sensor sends a door closing signal to the driving device 50, and the driving device 50 drives the rotating shaft 30 to rotate to close the second door body 20.

[0102] It should be noted that the detection device may also be a button-controlled switch or a voice recognition device. It is understandable that the specific form of the detection device is not unique.

[0103] Optionally, the door body assembly for the refrigeration equipment also includes an air outlet shaft 60 and a fan 70. The air outlet shaft 60 is arranged to penetrate the first door body 10 along the height direction of the first door body 10 and is rotatably connected to the first door body 10. Both ends of the air outlet shaft 60 are suitable for being hinged to the refrigeration equipment so that the first door body 10 rotates around the air outlet shaft 60. The air outlet shaft 60 is hollow inside to form an air duct. The air outlet shaft 60 is provided with an air inlet and a first air outlet 601. The first air outlet 601 faces the side where the opening of the accommodating cavity 101 is located; the fan 70 is connected to the air inlet of the air outlet shaft 60, and is used to drive air to flow from the air inlet into the air outlet shaft 60 and out from the first air outlet 601.

[0104] According to the embodiment of the present disclosure, the outlet shaft 60 is provided to penetrate the first door body 10 along the height direction of the first door body 10. The outlet shaft 60 is provided to be suitable for being hinged with the refrigeration equipment, so that the first door body 10 can be rotatably connected with the refrigeration equipment through the outlet shaft 60, and then the first door body 10 can be rotated relative to the refrigeration equipment along the axis where the outlet shaft 60 is located. The air duct is formed by the hollow inside of the outlet shaft 60, and an air inlet and a first air outlet 601 are provided, so that air can flow into the air duct from the air inlet and flow out of the air duct from the first air outlet 601. In this way, the outlet shaft 60 can not only play the role of connecting the first door body 10 with the refrigeration equipment, but also form an air curtain, reduce the installation space required to form the air curtain, and increase the storage space of the accommodating cavity 101. By setting the fan 70 and connecting the fan 70 with the air inlet of the air outlet shaft 60, the fan 70 can drive the air outside the accommodating chamber 101 to flow into the air duct and flow out of the air duct from the first air outlet 601. By setting the first air outlet 601 toward the side where the opening of the accommodating chamber 101 is located, a wind curtain can be formed on the opening side of the accommodating chamber 101 to prevent the cold air in the accommodating chamber 101 from flowing out, thereby effectively improving the storage effect of the accommodating chamber 101. By setting the fan 70 to turn on when the second door body 20 opens the accommodating chamber 101 and to turn off when the second door body 20 closes the accommodating chamber 101, energy consumption can be reduced to avoid energy waste, and the situation where the pressure in the accommodating chamber 101 is too high and the second door body 20 is automatically opened can be avoided.

[0105] It should be noted that the fan 70 can be disposed in the accommodating cavity 101, or the fan 70 can be disposed outside the first door body 10. It can be understood that the setting position of the fan 70 is not unique.

[0106] Optionally, the fan 70 is arranged in the accommodating cavity 101, and the end face of the first door body 10 facing away from the second door body 20 is provided with an air suction port and an air exhaust port; the door body assembly for the refrigeration equipment also includes: an air supply duct, one end of the air supply duct is connected to the air suction port, and the other end of the air supply duct is connected to the air suction side of the fan 70.

[0107] By adopting the embodiment of the present disclosure, by setting an air suction port and an air supply duct on the end face of the first door body 10 away from the second door body 20, not only can the fan 70 absorb the cold air in the refrigeration equipment and use the cold air in the refrigeration equipment to form an air curtain, and there is no need to improve the box of the refrigeration equipment, but also compared with the setting method of the fan 70 extracting high-temperature air outside the refrigeration equipment to form an air curtain, the effect of the air curtain in preventing cold leakage can be effectively improved. By setting an exhaust port on the end face of the first door body 10 away from the second door body 20, the air in the accommodating cavity 101 can flow out of the accommodating cavity 101 through the exhaust port, avoiding the situation where the high air pressure in the accommodating cavity 101 makes it difficult to close the second door body 20.

[0108] Optionally, the door body assembly for the refrigeration equipment also includes: a reset switch and a protrusion block, the reset switch is arranged on the first door body 10, and the reset switch is electrically connected to the fan 70 to control the fan 70 to be turned on or off; the protrusion block is arranged on the second door body 20 corresponding to the reset switch; wherein, when the second door body 20 is closed, the protrusion block squeezes the reset switch, and the reset switch disconnects the fan 70 to turn it off, and when the second door body 20 is opened, the reset switch connects the fan 70 to turn it on.

[0109] By adopting the embodiment of the present disclosure, by setting a reset switch and a protruding block and setting the reset switch and the protruding block correspondingly, when the second door body 20 closes the accommodating chamber 101, the fan 70 can be turned off in time, and when the second door body 20 opens the accommodating chamber 101, the fan 70 can be turned on in time, which can effectively reduce the energy consumption of the fan 70.

[0110] Optionally, the door body assembly for refrigeration equipment also includes: a sleeve 80, which is sleeved on the air outlet shaft 60 and is connected to the air outlet shaft 60 in a controllable rotation, and the sleeve 80 is provided with a second air outlet 801; wherein, when the second door body 20 opens the accommodating cavity 101, the sleeve 80 rotates to a position where the second air outlet 801 corresponds to the first air outlet 601; when the second door body 20 closes the accommodating cavity 101, the sleeve 80 covers the first air outlet 601.

[0111] According to the embodiment of the present disclosure, by providing the sleeve 80, the sleeve 80 can shield the first air outlet 601 of the air outlet shaft 60, so as to prevent the objects in the accommodating chamber 101 from falling from the first air outlet 601 into the air duct and affecting the formation of the wind curtain. By sleeve-arranging the sleeve 80 on the air outlet shaft 60, the force of the air outlet shaft 60 can also be distributed, and the upper limit of the force of the air outlet shaft 60 can be increased.

[0112] Optionally, the sleeve 80 is connected to the connecting member 41 and to the limiting member 42. The sleeve 80 rotates relative to the air outlet shaft 60 under the drive of the connecting member 41, and moves relative to the air outlet shaft 60 along the axial direction of the air outlet shaft 60 under the drive of the limiting member 42. The limiting member 42 can move between a first position and a second position. When the limiting member 42 is in the first position, the limiting member 42 is connected to the connecting member 41 and the sleeve 80 is connected to the connecting member 41, and the rotating shaft 30 can drive the limiting member 42 and the connecting member 41 to rotate. When the limiting member 42 is in the second position, the limiting member 42 is disconnected from the connecting member 41, and the sleeve 80 is disconnected from the connecting member 41.

[0113] In this way, by connecting the sleeve 80 with the connecting member 41, the connecting member 41 can drive the sleeve 80 to rotate relative to the air outlet shaft 60, so that the second air outlet 801 of the sleeve 80 rotates to a position corresponding to or covering the first air outlet 601 of the air outlet shaft 60. By connecting the sleeve 80 with the limiting member 42, the limiting member 42 can drive the sleeve 80 to move, so that the sleeve 80 moves along the axial direction of the air outlet shaft 60. By enabling the limiting member 42 to move between the first position and the second position, when the limiting member 42 is in the first position, the limiting member 42 is connected to the connecting member 41 and the sleeve 80 is connected to the connecting member 41, and the rotating shaft 30 can drive the limiting member 42 and the connecting member 41 to rotate; when the limiting member 42 is in the second position, the limiting member 42 is disconnected from the connecting member 41, and the sleeve 80 is disconnected from the connecting member 41. In this way, when the stopper 42 is in the first position, the user can drive the rotating shaft 30 to rotate, and at the same time open the second door body 20, the second air outlet 801 of the sleeve 80 is rotated to the corresponding position of the first air outlet 601. When the stopper 42 is in the second position, the user cannot drive the second door body 20 to open by the rotating shaft 30.

[0114] Specifically, a connecting structure 81 is provided on the sleeve 80 , and the connecting structure 81 is arranged corresponding to the connecting member 41 .

[0115] In this way, when the rotating shaft 30 rotates, under the action of the connecting member 41 and the connecting structure 81 , the sleeve 80 rotates relative to the air outlet shaft 60 .

[0116] Exemplary, combined Figures 7 to 10 As shown in , the connecting member 41 is a gear structure, and the connecting structure 81 is a transmission gear structure adapted to the gear structure, and the two are meshed with each other.

[0117] Thus, when the connecting member 41 rotates, the connecting structure 81 can be driven to rotate. By adopting gear transmission, the transmission accuracy is high, and the angle of rotation of the sleeve 80 can be accurately controlled to ensure that the second air outlet 801 of the sleeve 80 corresponds to the first air outlet 601 of the air outlet shaft 60.

[0118] Exemplary, combined Figure 8 and Fig.10 As shown in the figure, the sleeve 80 is connected to the limit member 42 through a connecting rod assembly 83, and the connecting rod assembly 83 is rotatably connected to the sleeve 80. The connecting rod assembly 83 includes a first connecting rod 831, a second connecting rod 832 and a ring sleeve 833. The first connecting rod 831 is provided with a slide rail 802, and the second connecting rod 832 is provided with a slider adapted to the slide rail 802, so that the first connecting rod 831 and the second connecting rod 832 can slide relative to each other. The ring sleeve 833 is sleeved on the sleeve 80 and is rotatably connected to the sleeve 80. The ring sleeve 833 is connected to one end of the first connecting rod 831.

[0119] In this way, by providing the connecting rod assembly 83 , the connecting rod assembly 83 can ensure that the limiting member 42 drives the sleeve 80 to move along the extension direction of the air outlet shaft 60 without affecting the rotation of the sleeve 80 and the independent rotation of the limiting member 42 .

[0120] Optionally, the angle of the air outlet axis 60 corresponding to the opening of the second air outlet 801 is greater than the angle of the air outlet axis 60 corresponding to the first air outlet 601 .

[0121] In this way, when the second door body 20 is opened at different angles, the second air outlet 801 of the sleeve 80 will not block the air outlet 601 of the air outlet shaft 60 from outlet air, so that the air outlet shaft 60 can outlet air no matter how much the second door body 20 is opened.

[0122] Optionally, the air outlet shaft 60 is provided with a limiting column 82, and the lower end of the sleeve 80 is provided with a sliding groove compatible with the limiting column 82; when the limiting member 42 moves from the first position to the second position, the sleeve 80 rotates relative to the air outlet shaft 60 under the limitation of the limiting column 82 and the sliding groove, so that the second air outlet 801 rotates to the position corresponding to the first air outlet 601.

[0123] By adopting the embodiment of the present disclosure, by setting a limit column 82 and a slide groove, when the limit member 42 moves from the first position to the second position, the sleeve 80 moves downward under the drive of the limit member 42, and the slide groove of the sleeve 80 is adapted to the limit column 82. Under the limitation of the limit column 82, the sleeve 80 rotates relative to the air outlet shaft 60, and the second air outlet 801 of the sleeve 80 rotates to a position corresponding to the first air outlet 601, so that the first air outlet 601 is not blocked by the sleeve 80.

[0124] In this way, when the user does not open the second door body 20 by driving the limit member 42 through the rotating shaft 30, that is, manually opens the second door body 20, the air outlet shaft 60 can also discharge air to form an air curtain on the front side of the accommodating cavity 101, thereby reducing the amount of cold air leakage in the accommodating cavity 101 when the second door body 20 is opened.

[0125] Optionally, there are multiple first air outlets 601 , and the multiple first air outlets 601 are arranged side by side and spaced apart along the extension direction of the air outlet shaft 60 .

[0126] In this way, by setting multiple first air outlets 601 and arranging the multiple first air outlets 601 side by side and at intervals along the extension direction of the air outlet shaft 60, on the one hand, the air outlet uniformity of the first air outlet 601 can be improved, and on the other hand, the opening area of ​​the first air outlet 601 can be reduced, thereby reducing the possibility of objects falling from the first air outlet 601 into the air outlet shaft 60.

[0127] Optionally, the door body assembly for the refrigeration equipment also includes: a detector, which is arranged on the first door body 10 or the second door body 20, and is used to detect the position of the second door body 20 relative to the first door body 10; wherein the detector and the fan 70 are electrically connected, and the fan 70 is configured to receive detection information of the detector and control the operation of the fan 70 according to the detection information of the detector.

[0128] By adopting the embodiment of the present disclosure, a detector is set up. The detector can detect the position information of the second door body 20 relative to the first door body 10 and send the detection result to the fan 70. The fan 70 can determine whether the second door body 20 is open based on the detection result. When the second door body 20 is open, the fan 70 is turned on, and when the second door body 20 is closed, the fan 70 is turned off.

[0129] Specifically, the detector can be a distance sensor or a visual sensor. It can be understood that the specific form of the detector is not unique, as long as it can detect whether the second door body 20 is opened relative to the first door body 10, it belongs to one of the optional embodiments of the present application.
