[0002] Taking refrigerators as an example, refrigeration equipment is usually equipped with drawer doors to facilitate pulling out the entire storage space to store and access food. That is, part of the freezer or refrigerator is in the form of a drawer, and the drawer door can be fully pulled out, allowing users to easily view and access all food, especially items stored deep in the refrigerator.

[0003] Usually, the drawer door is connected to the box body by sliding on the slide rail, and the drawer door is pulled to open or close by the movement of the slide rail. When the door body is closed, the spring of the slide rail itself locks the door body. However, since the support method of the drawer door also mainly comes from the slide rail, the spring of the slide rail itself needs to overcome the load gravity of the door body and the inside of the drawer, the friction caused by the long-term wear of the slide rail, and the resistance caused by the frost inside the metal rail after the slide rail is refrigerated in the freezer. Once these resistances are greater than the elastic force of the slide rail's own spring, the door body will not be able to close tightly. Therefore, the drawer door of the existing refrigeration equipment has the problem that the door body is not tightly closed after long-term use, which affects the refrigeration performance of the refrigeration equipment.

[0032] See also Figure 1 , Figure 1 FIG. 1 shows a schematic diagram of the structure of a refrigeration device 100 in an embodiment of the present application. The refrigeration device 100 provided in an embodiment of the present application may be as follows: Figure 1 The refrigerator shown in the figure may also be other devices with refrigeration function, without limitation. The refrigeration device 100 includes a box body 110, a door body 120 and a locking assembly 130, wherein the box body 110 includes an open refrigeration space 111, and the refrigeration space 111 is used to hold items to be refrigerated. Figure 1 As shown, the door body 120 is slidably connected to the box body 110 and covers the opening. The door body 120 is configured to be able to move relative to the box body 110 on an opening path and a closing path in opposite directions, so that when the door body 120 is in the open position, the opening is open to take in and put in food, and when the door body 120 is in the closed position, the door body 120 and the box body 110 together enclose a closed refrigerated space 111.

[0033] Combination Figures 2 to 5 As shown, Figure 2 and Figure 5 A structural schematic diagram of the locking assembly 130 of the refrigeration device 100 in one embodiment of the present application is shown in different states. The locking assembly 130 is used to provide a force for the door body 120 to continue moving toward the direction of the box body 110 when the door body 120 is closed, so as to lock the door body 120 and the box body 110, thereby avoiding the problem of the door body 120 not being tightly closed.

[0034] like Figures 2 to 5As shown, the locking assembly 130 includes a driving member 131, a fixing member 132 and a moving member 133, wherein the fixing member 132 is fixedly connected to the door body 120, and the moving member 133 is rotatably connected to the box body 110, and the driving member 131 is used to drive the moving member 133 to rotate forward and reversely. It can be understood that forward rotation and reverse rotation only indicate that the rotation directions of the two are opposite, and are not intended to be limiting. Figure 2 In the perspective shown, the clockwise rotation of the moving member 133 is taken as the positive rotation, and the counterclockwise rotation is taken as the reverse rotation. Figure 5 As shown, the fixing member 132 is partially located on the opposite rotation path of the moving member 133. When the driving member 131 drives the moving member 133 to rotate in the opposite direction and causes the moving member 133 to abut against the fixing member 132, the locking assembly 130 applies force to the door body 120 to drive the door body 120 to move along the closing path to a position abutting against the cabinet 110, and keep the door body 120 abutting against the cabinet 110, so that the door body 120 remains abutting against the cabinet 110, thereby locking the door body 120 and the cabinet 110, and avoiding the problem of the door body 120 not closing tightly and affecting the refrigeration efficiency.

[0035] like Figures 2 to 5 As shown, in one embodiment, the locking assembly 130 further includes a telescopic rod 134 connected to the moving member 133, and the driving member 131 is used to drive the telescopic rod 134 to extend or shorten. The telescopic rod 134 can be extended in a direction parallel to the direction of the closing path, that is, the telescopic rod 134 can be extended in the direction of the closing path and the opening path, and the telescopic rod 134 extends and retracts to drive the moving member 133 to rotate relative to the box body 110. Figure 5 As shown, during the shortening of the telescopic rod 134, the fixing member 132 rotates in the reverse direction to gradually approach and abut against the fixing member 132. During the extension of the telescopic rod 134, the fixing member 132 rotates in the forward direction to gradually move away from the fixing member 132, thereby unlocking the door body 120 and preventing the moving member 133 from interfering with the movement of the fixing member 132 along the opening path of the door body 120. In other embodiments, the driving member 131 may also drive the moving member 133 to rotate through other transmission structures, such as transmission gears.

[0036] like Figure 5 As shown, in one embodiment, one end of the movable member 133 is a rotating end 1331, and the other end is a butting end 1332, the rotating end 1331 is rotatably connected to the box body 110, and the fixed member 132 is partially located on the rotation path of the butting end 1332, the rotating end 1331 and the fixed member 132 are respectively located on both sides of the telescopic rod 134, so that the telescopic rod 134 can drive the butting end 1332 of the movable member 133 to rotate around the rotating end 1331 when it is extended and retracted, so that the butting end 1332 is close to or away from the fixed member 132.

[0037] like Figures 2 to 5 As shown, in one embodiment, the moving member 133 is provided with a slide groove 1333, the slide groove 1333 is located between the rotating end 1331 and the abutting end 1332, the setting direction of the slide groove 1333 is set at an angle to the telescopic direction of the telescopic rod 134, and the telescopic rod 134 is slidably connected to the slide groove 1333, as shown in FIG. Figure 2 and Figure 5 As shown, when the telescopic rod 134 is in a shortened state, the telescopic rod 134 abuts against the side wall of one end of the slide slot 1333 and the abutting end 1332 abuts against the fixing member 132. Figure 4 and Figure 5 As shown, when the telescopic rod 134 is in the extended state, the telescopic rod 134 abuts against the side wall at the other end of the slide slot 1333 to limit the telescopic length of the telescopic rod 134 by the length of the slide slot 1333. In other embodiments, the telescopic rod 134 may also be rotatably connected to the fixing member 132 at one end and rotatably connected to the box body 110 at the other end. In this case, the telescopic rod 134 can also achieve the effect of driving the moving member 133 to rotate when it is extended.

[0038] like Figures 2 to 5 As shown, in one embodiment, the end surface of the fixed member 132 facing the movable member 133 is concavely provided with an opening groove 1321, as shown in FIG. Figure 5 As shown, the bottom of the opening groove 1321 is an avoidance surface 1322 that is shaped like the rotation path of the abutting end 1332 to prevent the fixing member 132 from interfering with the positive rotation of the moving member 133. Figure 3 As shown in FIG. 1 , when the abutting end 1332 abuts against the fixing member 132, there is a gap between the door body 120 and the box body 110. At this time, the abutting end 1332 abuts against a smaller area of ​​the fixing member 132. As the moving member 133 continues to rotate, the depth of the abutting end 1332 inserted into the opening groove 1321 increases until the door body 120 and the box body 110 are spaced apart. Figure 2 As shown, the abutting end 1332 is completely inserted into the opening groove 1321 and abuts against the fixing member 132, so that the abutting area of ​​the two is large and the force is evenly distributed.

[0039] During the opening process of the door body 120, if the user directly pulls the door body 120, the fixed member 132 drives the movable member 133 to rotate by a set angle, and the movable member 133 will move out of the moving path of the fixed member 132 to prevent the movable member 133 from interfering with the direct opening of the door body 120. In this embodiment, the movable member 133 is in an arc-shaped structure, so that the required rotation angle of the movable member 133 when leaving the moving path of the fixed member 132 is smaller.

[0040] like Figures 2 to 5 As shown, in one embodiment, the end surface of the fixed member 132 for abutting against the moving member 133 is shaped like the end surface of the moving member 133 abutting against the fixed member 132, so that the force between the two is evenly distributed.

[0041] In some embodiments, the driving member 131 can be configured to be controlled by a switch button connected to the control panel, so that when the user presses the switch button, the driving member 131 drives the telescopic rod 134 to extend and retract, and then drives the moving member 133 to rotate, so that the moving member 133 drives the fixing member 132 and the door body 120 to move toward the box body 110 and lock, so that the driving member 131 drives the door body 120 to automatically close and lock, but this has length requirements for the extension distance of the telescopic rod 134 and the rotation path length of the abutment end 1332 of the moving member 133. Figures 2 to 5 As shown, in the present embodiment, the retractable distance of the telescopic rod 134 is much smaller than the moving distance when the door body 120 is opened. In one embodiment, the driving member 131 is configured to be triggered when the door body 120 is located at a set position on the closing path and drive the moving member 133 to rotate in the opposite direction, so as to avoid the telescopic rod 134 from participating in the entire closing process of the door body 120, and only participate in the door body 120 when it is at the end of the closing path, that is, the door body 120 is about to close or even in a half-closed state, thereby realizing the locking function when the door body 120 is in a closed state, and reducing the participation of the telescopic rod 134 in the entire closing path, thereby reducing the structural requirements for the telescopic rod 134 and reducing production and maintenance costs.

[0042] Combination Figure 6 and Figure 7 As shown, in one embodiment, the telescopic rod 134 is convexly provided with a stopper 135, and the stopper 135 is located on the closing path of the door body 120, and when the door body 120 is located at the set position, the door body 120 abuts against the stopper 135, and the driving member 131 is configured to be triggered when the stopper 135 is subjected to force and drive the telescopic rod 134 to shorten. It can be understood that when the door body 120 abuts against the stopper 135 during the closing process, the door body 120 exerts a force on the stopper 135 to drive the telescopic rod 134 to shorten, and The applied force will cause load changes and other effects on the driver 131. The driver 131 itself will recognize the change and automatically start to shorten the telescopic rod 134, that is, to drive the moving rod to rotate in the opposite direction, so that the moving rod gradually approaches and abuts the fixed block, until the telescopic rod 134 is shortened to the point where the telescopic rod 134 abuts against the side wall at one end of the slide slot 1333. At this time, the abutting end 1332 abuts against the fixing member 132, completing the function of locking the door body 120 through the abutting force between the abutting end 1332 and the fixing member 132. In this embodiment, the driver 131 is a driving motor. In other embodiments, a position sensor that is triggered at a set position can also be set in the slide rail assembly of the door body 120 that is slidably connected to the box body 110, and the driver 131 is triggered after receiving the position signal of the position sensor.

[0043] like Figure 6 and Figure 8As shown, in one embodiment, the refrigeration device 100 also includes a trigger member 140, and the driving member 131 is controlled by the trigger member 140. When the trigger member 140 is triggered, the driving member 131 drives the telescopic rod 134 to extend, and then drives the stopper 135 to move along with the telescopic rod 134, so as to push the door body 120 to move on the opening path through the stopper 135, and at the same time drives the moving member 133 to rotate forward.

[0044] like Figure 1 As shown, the refrigeration device 100 is usually provided with other doors in the same plane as the outer end surface of the door body 120, and for the aesthetics of the refrigeration device 100, there is usually only a small gap between the door body 120 and the other doors, such as Figure 7 and Figure 8 As shown, in one embodiment, a handle groove 121 is provided at the top or bottom of the door body 120. It is understood that when other doors are above the door body 120, the handle groove 121 is provided at the top of the door body 120, and when other doors are below the door body 120, the handle groove 121 may also be provided at the bottom of the door body 120. Figure 7 As shown, when the telescopic rod 134 is in the extended state, the moving distance of the door body 120 is not less than the minimum distance between the handle groove 121 and the end face of the door body 120 away from the box body 110, so that the user can open the door body 120 through the handle groove 121. Preferably, when the telescopic rod 134 is in the extended state, the opening of the handle groove 121 mostly or completely protrudes from the plane where the outer end face of the door body 120 is located when the door body 120 is in the closed state, so as to stagger the other doors above and below the door body 120, so that the user can pull the door body 120 through the handle groove 121.

[0045] like Figure 7 and Figure 8 As shown, in one embodiment, the trigger 140 is connected to the box 110 and is arranged toward the door 120, and the trigger 140 is configured to be triggered when the door 120 continues to move toward the box 110 in the extension direction of the closed path. It is understandable that when the door 120 is in a fully closed state, since there is a sealing ring between the door 120 and the box 110 for sealing the gap between the two, when the door 120 is subjected to an external force, the door 120 still has the possibility of continuing to move a small distance toward the box 110 in the extension direction of the closed path, and the sealing ring is compressed to realize the movement of the door 120, but it does not affect the door 120 being in a fully closed state before the movement. In actual use, it is only necessary to adjust the trigger sensitivity of the trigger 140 so that the door 120 can be triggered when it moves a small distance under the external force, so that the user's door opening demand can be known through the trigger 140.

[0046] The refrigeration device 100 provided in the above solution, when in use:

[0047] When the door body 120 needs to be closed: the user pushes the door body 120 along the closing path. When the door body 120 reaches the set position, the door body 120 exerts a force on the stopper 135 and the telescopic rod 134 in the extended state in the direction of shortening the telescopic rod 134, so that the driving member 131 is triggered and started, and the telescopic rod 134 is shortened, that is, the moving rod is driven to rotate in the opposite direction, so that the moving rod gradually approaches and closes. Figure 3 As shown, the abutment fixing block is pressed against the Figure 2 As shown, the telescopic rod 134 is shortened until the telescopic rod 134 abuts against the side wall of one end of the slide groove 1333. At this time, the abutting end 1332 abuts against the fixing member 132, completing the function of locking the door body 120 through the abutting force between the abutting end 1332 and the fixing member 132.

[0048] When the door body 120 needs to be opened: the user presses the door body 120, so that the door body 120 continues to move toward the box body 110 in the extension direction of the closing path, and triggers the trigger member 140 arranged toward the door body 120. After the driving member 131 receives the electrical signal of the trigger member 140, it starts to drive the telescopic rod 134 to extend. At this time, the stopper 135 can push the door body 120 to move, and because the fixing member 132 is provided with an open groove 1321, the fixing member 132 will not interfere with the moving member 133 which is rotating in the forward direction driven by the telescopic rod 134, until the telescopic rod 134 is in a position as shown in FIG. Figure 4 In the extended state shown in FIG. Figure 7 As shown, at this time, the opening of the handle groove 121 mostly or completely protrudes from the plane where the outer end surface of the door body 120 is located when the door body 120 is in a closed state, so as to be staggered from other doors above and below the door body 120, making it convenient for the user to pull the door body 120 through the handle groove 121.

[0049] Alternatively, when the door body 120 needs to be opened, the user directly pulls the door body 120, and after the fixed member 132 drives the movable member 133 to rotate a set angle, the movable member 133 will move out of the moving path of the fixed member 132 to avoid the movable member 133 interfering with the direct opening of the door body 120.

[0050] The refrigeration equipment 100 provided in the above scheme connects the fixing part 132 of the locking assembly 130 to the door body 120, the moving part 133 is rotatably connected to the box body 110, and the fixing part 132 is set on the rotation path of the moving part 133, and the moving part 133 is powered by the driving part 131, so that when the moving part 133 abuts against the fixing part 132, under the force of the driving part 131, the locking assembly 130 has the effect of driving the door body 120 to move along the closing path to abut against the box body 110, and keep the door body 120 abutting against the box body 110, so that the door body 120 remains abutting against the box body 110, achieving the effect of assisting the closing of the door, locking the door body 120 and the box body 110, and avoiding the problem of the door body 120 not closing tightly and affecting the refrigeration efficiency.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
