[0077] As shown in Figures 1 to 20 The first aspect of the present application provides a door assembly, comprising a door body 100, a driving device, a bracket and a clutch mechanism; wherein the door body 100 is formed with a handle slot 102; the bracket is hinged to the door body 100 and a cover plate assembly is installed on the bracket; the clutch mechanism is installed on the bracket; the driving device is adapted to drive the bracket to switch between a pressing state and a reset state; in the pressing state, the cover plate assembly avoids the handle slot 102, and in the reset state, the cover plate assembly shields the handle slot 102; during the switching from the reset state to the pressing state, the clutch mechanism is adapted to adjust the movement speed of the cover plate assembly.

[0078] According to the door assembly provided by the first aspect of the present application, by setting the clutch mechanism on the bracket and adjusting the movement speed of the cover plate assembly during the switching of the bracket from the reset state to the pressing state through the clutch mechanism, the bracket can be switched from the reset state to the pressing state faster, which facilitates the user to quickly hold the handle slot 102 to open the door body 100. At the same time, since the clutch mechanism is set, the working time of the driving device can be reduced, and the switching speed of the bracket can be improved only by the structural design of the clutch mechanism.

[0079] The door assembly provided by the embodiment of the present application can be applied to a single-door refrigerator or a double-door refrigerator.

[0080] The door body 100 is provided with a handle slot 102 for a user to hold. When the handle slot 102 is exposed, the user can hold the handle slot 102 to open the door body 100.

[0081] It should be noted that, in combination with Figure 1 and Figure 2 , the position of the door assembly on the door body 100 is not limited in the embodiment of the present application.

[0082] When the door body 100 is one, the handle slot 102 can be formed at a position close to the edge of the door body 100. That is, when the driving device drives the cover plate assembly to switch to the pressing state, the handle slot 102 arranged at the edge of the door body 100 is exposed.

[0083] When the door body 100 is multiple, the handle slot 102 can be formed at a side edge position of any one of the door bodies 100. Of course, the handle slot 102 can also be formed at a non-edge position of the door body 100 according to needs. Thus, when the user needs to open the current door body 100, the driving device can drive the cover plate assembly on the door body 100, and then the handle slot 102 on the door body 100 is exposed to facilitate the user to hold the handle slot 102 to open the door body 100.

[0084] Alternatively, the driving device is used to drive the cover plate assembly on the door body 100 to expose the handle slot 102 on the adjacent door body 100, and then the user can open the adjacent door body 100. In other words, the user can flexibly select to open the corresponding door body 100 according to actual needs. That is, when the door body 100 is multiple, the handle slot 102 can be arranged on two adjacent door bodies 100, so as to facilitate the user to open the required door body 100.

[0085] In the embodiment of the present application, the door assembly further comprises a support 144 mounted on the door body 100. For example, the support 144 can be mounted in the foamed layer of the door body 100 or detachably mounted on the door body 100 by means of bolts, clamps or the like. The support 144 is formed with the handle slot 102 described above.

[0086] One side of the bracket is hinged to the support 144, and the other side of the bracket is mounted with the cover plate assembly. The bracket is adapted to switch between the pressing state and the reset state. In the pressing state, the cover plate assembly avoids the handle slot 102, and in the reset state, the cover plate assembly shields the handle slot 102.

[0087] As mentioned above, when the bracket is in the pressing state, the cover plate assembly installed on the bracket can avoid the handle slot 102, so that the handle slot 102 is exposed, at which time the user can hold the handle slot 102 to open the door body 100. When the bracket is in the reset state, the cover plate assembly installed on the bracket can shield the handle slot 102, so that the door body 100 is in a flat and simple state. The pressing state mentioned here refers to when the driving device drives the bracket to drive the cover plate assembly to move towards the position of being retracted in the door body 100, when the cover plate assembly exposes the handle slot 102, at this time, the bracket is in the pressing state; the reset state refers to the bracket driving the cover plate assembly to switch from the state of being retracted in the door body 100 to the state of being flush with the outer surface of the door body 100, at this time, the bracket is in the reset state.

[0088] In the embodiment of the present application, the driving device can be installed in the support 144, or can be directly installed in the door body 100. The driving device is mainly used to control the bracket to switch between the pressing state and the reset state.

[0089] According to one embodiment of the present application, the bracket includes a first rotating bracket and a second rotating bracket. One side of the first rotating bracket is hinged to the support 144, and the other side of the first rotating bracket is hinged to the cover plate assembly; one side of the second rotating bracket is hinged to the support 144, and the other side of the second rotating bracket is hinged to the cover plate assembly; the driving device is adapted to drive the first rotating bracket and / or the second rotating bracket to drive the cover plate assembly to move in a direction perpendicular to the door body 100.

[0090] Referring to Figure 2 , the first rotating bracket and the second rotating bracket jointly constitute the bracket in the embodiment of the present application. One side of the first rotating bracket and one side of the second rotating bracket are respectively hinged to the support 144, and the other side of the first rotating bracket and the other side of the second rotating bracket are respectively hinged to the cover plate assembly. Thus, the cover plate assembly can move relative to the support 144 under the hinging action of the first rotating bracket and the second rotating bracket.

[0091] The driving device can be connected with the first rotating bracket or the second rotating bracket respectively, or the driving device can also be connected with the first rotating bracket and the second rotating bracket simultaneously. Through the driving of the driving device, the first rotating bracket and / or the second rotating bracket can be driven to rotate, thereby achieving the purpose of driving the cover plate assembly to move relative to the support 144. In the embodiment of the present application, the first rotating bracket and the second rotating bracket can drive the cover plate assembly to move in a direction perpendicular to the door body 100. It can be understood that the cover plate assembly can translate in a direction perpendicular to the door body 100 relative to the door body 100.

[0092] According to one embodiment of the present application, the first rotating support comprises a synchronous shaft 110, a first connecting shaft 112 and a first connecting member 114; the second rotating support comprises two second connecting shafts 116 and a second connecting member 118. The two ends of the synchronous shaft 110 are hingedly connected to the support 144, the two ends of the first connecting shaft 112 are hingedly connected to the cover plate assembly, and the first connecting member 114 is connected between the synchronous shaft 110 and the first connecting shaft 112; the two ends of one of the second connecting shafts 116 are hingedly connected to the support 144, the two ends of the other of the second connecting shafts 116 are hingedly connected to the cover plate assembly, and the second connecting member 118 is connected between the two second connecting shafts 116.

[0093] In other words, referring to Figure 2 , the two ends of the synchronous shaft 110 and the two ends of one of the second connecting shafts 116 are hingedly connected to the support 144, and the two ends of the first connecting shaft 112 and the two ends of the other of the second connecting shafts 116 are hingedly connected to the cover plate assembly. In order to improve the connection stability between the synchronous shaft 110 and the first connecting shaft 112, the first connecting member 114 is further connected between the synchronous shaft 110 and the first connecting shaft 112, and the second connecting member 118 is further connected between the two second connecting shafts 116.

[0094] It should be noted that in the embodiment of the present application, the synchronous shaft 110 is a long shaft, and the cross section of the synchronous shaft 110 is a polygonal shaft. The first connecting shaft 112 can be arranged to have the same width as the first connecting member 114, and the two second connecting shafts 116 can be arranged to have the same width as the second connecting member 118.

[0095] In the embodiment of the present application, the hinged points of the synchronous shaft 110 and the support 144, the hinged points of one of the second connecting shafts 116 and the support 144, the hinged points of the first connecting shaft 112 and the cover plate assembly, and the hinged points of the other of the second connecting shafts 116 and the cover plate assembly, sequentially connecting these four hinged points can form a parallelogram. Since the hinged points of the synchronous shaft 110 and the support 144 and the hinged points of one of the second connecting shafts 116 and the support 144 are fixed points, the relative distance between these two hinged points and the inclination angle of the line connecting these two hinged points are also fixed, thus the distance between the hinged points of the first connecting shaft 112 and the cover plate assembly and the hinged points of the other of the second connecting shafts 116 and the cover plate assembly is also equal, and the line connecting the hinged points of the first connecting shaft 112 and the cover plate assembly and the hinged points of the other of the second connecting shafts 116 and the cover plate assembly is parallel to the line connecting the hinged points of the synchronous shaft 110 and the support 144 and the hinged points of one of the second connecting shafts 116 and the support 144, so the cover plate assembly can move along the direction perpendicular to the door body 100.

[0096] It should be noted that during the movement of the cover assembly from the position of obscuring the handle groove 102 to the position of avoiding the handle groove 102, the cover assembly first moves towards... Figure 4 The downward translation is approximately 1 to 3 millimeters, and then the direction is perpendicular to... Figure 4 It then moves inwards by approximately 1 to 3 millimeters, eventually reaching the position to avoid the handle groove 102. Similarly, as the cover assembly moves from the position avoiding the handle groove 102 to the position covering the handle groove 102, the cover assembly first moves inwards... Figure 4 The downward translation is approximately 1 to 3 millimeters, and then the direction is perpendicular to... Figure 4 It then moves outwards by a distance of about 1 to 3 millimeters, eventually reaching the position where the handle groove 102 is concealed.

[0097] To limit the relative position between the first connecting shaft 112 and the first connecting member 114, first limiting members 120 are provided at both ends of the first connecting shaft 112. The first limiting members 120 may be limiting pins or the like. Similarly, to limit the relative position between the second connecting shaft 116 and the second connecting member 118, second limiting members 122 are provided at both ends of the second connecting shaft 116. The second limiting members 122 may be limiting pins or the like.

[0098] In other embodiments, the first rotating bracket and the second rotating bracket may also be configured as a rectangular frame. That is, in this implementation, the first rotating bracket and the second rotating bracket may not be provided with the synchronous shaft 110, the first connecting shaft 112, the second connecting shaft 116 and the corresponding connecting parts, but instead use an integrally formed rectangular frame structure to replace the above-mentioned components.

[0099] According to one embodiment of the present invention, the cover plate assembly includes a cover plate base 132 and a cover plate body 134; both ends of the first connecting shaft 112 and the other end of the first connecting shaft 112 are respectively hinged to the cover plate base 132; the cover plate body 134 is mounted on the cover plate base 132.

[0100] See also Figure 3 The first connecting shaft 112 and the other second connecting shaft 116 are hinged at both ends to the cover plate base 132. A cover plate body 134 is also installed on the cover plate base 132. The cover plate body 134 and the cover plate base 132 can be fixed together by means of adhesive, snap-fit, etc. In other words, when the driving device drives the first rotating bracket and / or the second rotating bracket to move, the first rotating bracket and the second rotating bracket can drive the cover plate base 132 and the cover plate body 134 to switch between the position of avoiding the handle groove 102 and the position of covering the handle groove 102. In addition, the cover plate body 134 can be made of the same material as the outer surface of the door body 100, which can further improve the appearance consistency of the outer surface of the door body 100.

[0101] In the embodiment of the present application, the driving device comprises a driving member 124, which is installed on the door body 100 and connected to the synchronous shaft 110. A transmission shaft sleeve 126 is further connected between the driving member 124 and the synchronous shaft 110. By arranging the transmission shaft sleeve 126, the driving member 124 and the synchronous shaft 110 can be better connected in transmission.

[0102] In the embodiment of the present application, a notch 128 is further arranged on the transmission shaft sleeve 126, and a push rod 130 adapted to the notch 128 is arranged on the driving member 124. The width of the notch 128 is greater than that of the push rod 130. The notch 128 can be arranged at the edge of the transmission shaft sleeve 126 along the circumferential direction of the transmission shaft sleeve 126. It can be understood that the push rod 130 can move in the notch 128, and the transmission shaft sleeve 126 can be driven to move when the push rod 130 abuts against the side wall of the notch 128.

[0103] Referring to Figure 8 , Figure 11 , Figure 14 , Figure 17 and Figure 20 , in the embodiment of the present application, the opposite sides of the notch 128 are provided with a first side wall 129 and a second side wall 131. The first side wall 129 and the second side wall 131 can be parallel or arranged at an angle.

[0104] When the bracket is switched from the reset state to the pressing state, the push rod 130 abuts against the first side wall 129 to drive the transmission shaft sleeve 126 to move. After the push rod 130 and the first side wall 129 abut against each other, the first side wall 129 can be forced to drive the synchronous shaft 110 to rotate, so that the synchronous shaft 110 can drive the bracket to switch from the reset state to the pressing state.

[0105] When the bracket moves to the reset state, in order to ensure that the driving member 124 can timely drive the transmission shaft sleeve 126 to reverse when the driving member 124 reverses, the driving member 124 reverses appropriately to drive the push rod 130 to reverse. When the push rod 130 reverses to the position abutting against the second side wall 131, the push rod 130 stops. In this way, when the driving member 124 reverses, the second side wall 131 can be directly abutted to force the second side wall 131.

[0106] Similarly, when the bracket is switched from the pressing state to the reset state, the push rod 130 abuts against the second side wall 131 to drive the transmission shaft sleeve 126 to move. After the push rod 130 and the second side wall 131 abut against each other, the second side wall 131 can be forced to drive the synchronous shaft 110 to rotate, so that the synchronous shaft 110 can drive the bracket to switch from the pressing state to the reset state.

[0107] When the bracket moves to the pressing state, in order to ensure that the drive component 124 can promptly drive the transmission shaft sleeve 126 to reverse when it reverses, the drive component 124 will reverse appropriately to drive the lever 130 to reverse. The lever 130 will stop when it reverses to the position of contact with the first side wall 129. With this setting, when the drive component 124 reverses, it can directly form an abutment relationship with the first side wall 129 to apply force to the first side wall 129.

[0108] Understandably, when the cover assembly is in the reset state, the lever 130 and the notch 128 are in the same position as... Figure 8 The state shown; when the cover assembly is switching from the reset state to the pressed state, the lever 130 and the notch 128 are in the state as shown. Figure 11 The state shown; when the cover assembly has just switched to the pressed state, the lever 130 and the notch 128 are in the position as shown. Figure 14 The state shown; when the cover assembly is in the pressed state, the lever 130 and the notch 128 are in the position as shown. Figure 17 The state shown; when the cover plate assembly is switching from the pressed state to the reset state, the lever 130 and the notch 128 are in the state as shown. Figure 20 The state shown; when the cover plate assembly is in the reset state, the lever 130 and the notch 128 are in the state as shown. Figure 8 The state shown.

[0109] Please continue reading Figure 3 In this embodiment of the invention, the door assembly further includes a light strip and a lampshade 136 covering the light strip. The light strip is detachably mounted on the support 144, and the lampshade 136 can be snapped onto the light strip. Of course, in some other embodiments, the light strip can also be directly mounted below the cover body 134 and move synchronously with the cover body 134.

[0110] By installing a light strip on the support 144, the light strip can illuminate the position of the cover assembly when a person approaches the door 100, allowing the user to accurately know the specific location of the cover assembly. The light strip automatically turns off when the door 100 is closed.

[0111] In this embodiment of the invention, a detection element is installed on the door 100 and / or the bracket. The detection element can be used to detect whether a human body is approaching, to detect the opening and closing state of the door 100, or to detect whether a user has left. When the detection element detects the above situations, it can generate a detection signal for controlling the drive device.

[0112] Specifically, when the detector detects a human body approaching, it indicates that the user requests to open the door, and the detector generates a detection signal indicating that the door 100 is open. After receiving the detection signal, the drive device can switch the first rotating bracket and / or the second rotating bracket from the reset state to the pressing state.

[0113] When the door body 100 is switched from the opening state to the closing state, the detection member can detect the action of the door body 100 to generate a detection signal representing that the door body 100 is closed; or when the user leaves, the detection member can detect that the human body has left the vicinity of the door body 100 to generate a detection signal representing that the door body 100 can be closed. When the driving device receives the detection signal, the driving device can act to switch the first rotating support and / or the second rotating support from the pressing state to the reset state.

[0114] It should be noted that the detection member can be a sensor for detecting the distance of the human body (such as an infrared sensor, a laser sensor), and can also be a sensor for detecting the biological characteristics of the human body, such as a face recognition device, a voice recognition device, and a pressure sensor. When the user touches a certain area of the door body 100, a detection signal is generated, that is, the type and excitation mode of the detection member are not limited in the present application, as long as the opening and closing requirements of the user can be determined.

[0115] In the embodiment of the present application, the running time of the motor can also be set to automatically stop after running for a certain period of time, for example, when the motor drives the first rotating support to switch from the reset state to the pressing state and encounters a foreign object, the motor stops automatically after running for a certain period of time. After the foreign object is removed, the cover body 134 can be manually pressed to move the support to the pressing state, which can effectively avoid the situation that the motor is damaged due to a large torque.

[0116] In addition, by setting the running time of the motor to a preset time, the motor can automatically stop after the running time reaches the preset time, so that an additional sensor can be omitted, further reducing the design and manufacturing costs. In addition, the user can also maintain the support in the pressing state according to the actual use requirement to facilitate the user to open the door body 100 at any time. Correspondingly, the purpose of maintaining the support in the pressing state can be achieved by controlling the motor.

[0117] The clutch mechanism provided in the embodiment of the present application will be introduced as follows:

[0118] As Figure 3As shown, according to one embodiment of the present application, the clutching mechanism comprises a first clutching sleeve 104, a second clutching sleeve 106 and an elastic member 108; the first clutching sleeve 104 is installed on the synchronizing shaft 110; the second clutching sleeve 106 is installed on the synchronizing shaft 110 through the installation sleeve 107; the elastic member 108 is sleeved on the synchronizing shaft 110 and abuts between the side of the second clutching sleeve 106 away from the first clutching sleeve 104 and the installation sleeve 107; one of the opposite sides of the first clutching sleeve 104 and the second clutching sleeve 106 is provided with the first plane 138 and the first inclined plane 140 connected with each other, and the other is provided with the second plane 142; in the case that the first plane 138 and the second plane 142 abut against each other, the elastic member 108 is in the compressed state, and in the case that the first plane 138 and the second plane 142 are separated from each other, the elastic member 108 is in the resetting process.

[0119] In the embodiment of the present application, the first clutching sleeve 104 can be fixedly arranged on the synchronizing shaft 110, and the second clutching sleeve 106 can be rotatably sleeved on the sleeve. It should be noted that the first clutching sleeve 104 mentioned herein is fixedly arranged on the synchronizing shaft 110, which means that the first clutching sleeve 104 can rotate synchronously with the synchronizing shaft 110, but can slide along the axial direction of the synchronizing shaft 110. An elastic member 108 is arranged between the side of the second clutching sleeve 106 away from the first clutching sleeve 104 and the installation sleeve 107, one end of the elastic member 108 is fixed relative to the axial position of the synchronizing shaft 110, and the other end abuts against the side of the second clutching sleeve 106 away from the first clutching sleeve 104; the elastic member 108 herein can use a spring, a torsion spring, etc. In this way, the second clutching sleeve 106 can always abut against the first clutching sleeve 104 under the elastic force of the elastic member 108, and the purpose of preventing the support from rotating due to the weight can be effectively achieved.

[0120] For example, the first clutching sleeve 104 is provided with the first plane 138 and the first inclined plane 140 connected with each other, and the second clutching sleeve 106 is provided with the second plane 142.

[0121] For example, the first clutching sleeve 104 is provided with the first plane 138 and the first inclined plane 140 connected with each other, and the second clutching sleeve 106 is provided with the second plane 142. Figure 7 、 Figure 10 、 Figure 13 、 Figure 16 and Figure 19When the first plane 138 on the first clutch sleeve 104 and the second plane 142 on the second clutch sleeve 106 are in contact with each other, the elastic member 108 is in a compressed state, that is, the two can be pressed against each other under the elastic restoring force of the elastic member 108. When the driving member 124 drives the second clutch sleeve 106 to move, the second clutch sleeve 106 rotates relative to the first clutch sleeve 104, and the first plane 138 and the second plane 142 gradually deviate from each other. When the critical point of the first plane 138 and the second plane 142 is passed, the first inclined surface 140 and the second plane 142 are in contact with each other, at this time, the elastic member 108 is switched from the compressed state to the original state, the friction between the second clutch sleeve 106 and the first clutch sleeve 104 is reduced, and then the bracket can be quickly switched to the pressing state, and then the cover plate assembly can be quickly switched to the pressing state, and the user can open the door body 100. It can be understood that in the above process, first, the relative rotation of the first clutch sleeve 104 and the second clutch sleeve 106 is driven by the driving member 124, and then the elastic restoring force of the elastic member 108 accelerates the relative rotation of the first clutch sleeve 104 and the second clutch sleeve 106, and then the cover plate assembly can be quickly switched to the pressing state.

[0122] Of course, the first clutch sleeve 104 and the second clutch sleeve 106 can also be provided with a plane and an inclined surface structure on the opposite side. For example, the first inclined surface 140 and the second inclined surface connected to each other can be provided on the side of the first clutch sleeve 104 facing the second clutch sleeve 106, and the first plane 138 is arranged between the first inclined surface 140 and the second inclined surface. The third inclined surface and the fourth inclined surface connected to each other are arranged on the side of the second clutch sleeve 106 facing the first clutch sleeve 104, and the second plane 142 is arranged between the third inclined surface and the fourth inclined surface.

[0123] When the first inclined surface 140 on the first clutch sleeve 104 and the third inclined surface on the second clutch sleeve 106 are in contact with each other, at this time, the elastic member 108 is in a non-compressed state, that is, the two can be tightly abutted against each other under the elastic restoring force of the elastic member 108. When the driving member 124 drives the second clutch sleeve 106 to act, the second clutch sleeve 106 rotates relative to the first clutch sleeve 104, and the first inclined surface 140 and the third inclined surface gradually stagger with each other. When the first plane 138 and the second plane 142 are in contact with each other, the elastic member 108 is in a compressed state; when the critical point of the first plane 138 and the second plane 142 is passed, the second inclined surface and the fourth inclined surface are in contact with each other, at this time, the elastic member 108 is switched from the compressed state to the original state, the frictional force between the second clutch sleeve 106 and the first clutch sleeve 104 is reduced, and then the bracket can be quickly switched to the pressing state, and then the cover plate assembly can be quickly switched to the pressing state, facilitating the user to open the door body 100. It can be understood that in the above process, first, the first clutch sleeve 104 and the second clutch sleeve 106 are relatively rotated by the driving of the driving member 124, and then the process of relatively rotating the first clutch sleeve 104 and the second clutch sleeve 106 is accelerated by the elastic restoring force of the elastic member 108, and then the cover plate assembly can be quickly switched to the pressing state.

[0124] On the contrary, when the driving member 124 drives the second clutch sleeve 106 to reverse, the second clutch sleeve 106 reversely rotates relative to the first clutch sleeve 104, and the second inclined surface and the fourth inclined surface gradually stagger with each other. When the first plane 138 and the second plane 142 are in contact with each other, the elastic member 108 is in a compressed state; when the critical point of the first plane 138 and the second plane 142 is passed, the first inclined surface 140 and the third inclined surface are in contact with each other, at this time, the elastic member 108 is switched from the compressed state to the original state, the frictional force between the second clutch sleeve 106 and the first clutch sleeve 104 is reduced, and then the bracket can be quickly switched to the reset state, and then the cover plate assembly can be quickly switched to the reset state, facilitating the cover plate assembly to quickly switch to the reset state. It can be understood that in the above process, first, the first clutch sleeve 104 and the second clutch sleeve 106 are relatively rotated by the driving of the driving member 124, and then the process of relatively rotating the first clutch sleeve 104 and the second clutch sleeve 106 is accelerated by the elastic restoring force of the elastic member 108, and then the cover plate assembly can be quickly switched to the reset state.

[0125] Of course, a structure of one flat surface and two inclined surfaces can also be arranged on one of the opposite sides of the first clutch sleeve 104 and the second clutch sleeve 106. For example, the first inclined surface 140 and the second inclined surface can be arranged on the side of the first clutch sleeve 104 facing the second clutch sleeve 106, and the first flat surface 138 is arranged between the first inclined surface 140 and the second inclined surface; and the second flat surface 142 is arranged on the side of the second clutch sleeve 106 facing the first clutch sleeve 104.

[0126] When the first inclined surface 140 on the first clutch sleeve 104 and the second flat surface 142 on the second clutch sleeve 106 are in contact with each other, at this time, the elastic member 108 is in a non-compressed state, that is, the two can be tightly contacted with each other under the elastic restoring force of the elastic member 108. When the driving member 124 drives the second clutch sleeve 106 to act, the second clutch sleeve 106 rotates relative to the first clutch sleeve 104, and the first inclined surface 140 and the second flat surface 142 gradually stagger with each other. When the first flat surface 138 and the second flat surface 142 are in contact with each other, the elastic member 108 is in a compressed state; when the critical point of the first flat surface 138 and the second flat surface 142 is passed, the second inclined surface and the second flat surface 142 are in contact with each other, at this time, the elastic member 108 is switched from the compressed state to the original state, the friction between the second clutch sleeve 106 and the first clutch sleeve 104 is reduced, and then the bracket can be quickly switched to the pressing state, and then the cover plate assembly can be quickly switched to the pressing state, and the user can open the door body 100. It can be understood that in the above process, first, the relative rotation of the first clutch sleeve 104 and the second clutch sleeve 106 is driven by the driving member 124, and then the elastic restoring force of the elastic member 108 accelerates the relative rotation of the first clutch sleeve 104 and the second clutch sleeve 106, and then the cover plate assembly can be quickly switched to the pressing state.

[0127] In contrast, when the driving member 124 drives the second clutch sleeve 106 to reverse, the second clutch sleeve 106 reversely rotates relative to the first clutch sleeve 104, and the second inclined surface gradually deviates from the second flat surface 142. When the first flat surface 138 and the second flat surface 142 contact each other, the elastic member 108 is in a compressed state. When the first flat surface 138 and the second flat surface 142 pass the critical point, the first inclined surface 140 and the second flat surface 142 contact each other. At this time, the elastic member 108 switches from the compressed state to the original state, the friction between the second clutch sleeve 106 and the first clutch sleeve 104 decreases, and the bracket can quickly switch to the reset state, and the cover plate assembly can quickly switch to the reset state, facilitating the cover plate assembly to quickly switch to the reset state. It can be understood that in the above process, the first clutch sleeve 104 and the second clutch sleeve 106 are first driven to rotate relative to each other by the driving member 124, and then the elastic restoring force of the elastic member 108 accelerates the relative rotation of the first clutch sleeve 104 and the second clutch sleeve 106, and the cover plate assembly can quickly switch to the reset state.

[0128] In addition, it should be noted that when the synchronous shaft 110 is stuck by foreign matter during forward or reverse rotation, the transmission connection between the first clutch sleeve 104 and the second clutch sleeve 106 is resisted. At this time, although the spring can still tightly push the second clutch sleeve 106 against the first clutch sleeve 104, because the resistance is much greater than the elastic support force of the spring, the rotation connection between the first clutch sleeve 104 and the second clutch sleeve 106 is no longer stable. That is, the driving shaft no longer synchronously moves with the second clutch sleeve 106 at this time, and the motor only drives the first clutch sleeve 104 to rotate, and the synchronous shaft 110 no longer rotates.

[0129] When the foreign matter is removed, the second clutch sleeve 106 is again meshed and driven with the first clutch sleeve 104 under the elastic support force of the elastic member 108, and the synchronous shaft 110 can continue to transmit power between the motor.

[0130] When the power is off, the motor stops, and if the cover plate assembly is in the reset state, the user can directly press the cover plate assembly to switch the cover plate assembly from the reset state to the pressed state. Because the pressure applied by the user to the cover plate assembly is much greater than the elastic force of the elastic member 108 between the first clutch sleeve 104 and the second clutch sleeve 106, the user can still hold the exposed handle slot 102 to open the door body 100.

[0131] It can be understood that, in the embodiment of the present application, due to the size precision of parts or assembly, etc., there is a certain gap between the output shaft of the motor and the second clutch shaft sleeve 106. When the motor starts to rotate, the cover plate assembly cannot move under the action of the motor in a short time because of the gap between the output shaft of the motor and the second clutch shaft sleeve 106. The support will move a certain distance in the direction of approaching the inner side of the door body 100 under the action of gravity until the motor and the second clutch shaft sleeve 106 are engaged, and then the support will continue to move under the drive of the motor. Because the movement of the support under the action of gravity does not match the speed of the motor drive, the movement process is not smooth. After adding the clutch mechanism, the friction torque generated when the synchronous shaft 110 drives the first clutch shaft sleeve 104 and the second clutch shaft sleeve 106 to rotate is greater than or equal to the torque generated by the gravity acting on the cover plate assembly. When the motor starts to rotate, the cover plate assembly remains stationary under the friction torque until the motor and the second clutch shaft sleeve 106 are engaged, and then the cover plate assembly starts to move under the drive of the motor, thereby ensuring that the movement speed of the cover plate assembly is more stable and the entire movement process is more smooth.

[0132] It should be noted that the driving member 124 is connected to one end of the synchronous shaft 110 facing the second clutch shaft sleeve 106. By such arrangement, the second clutch shaft sleeve 106 can be driven to move relative to the first clutch shaft sleeve 104.

[0133] The second aspect embodiment of the present application provides a storage cabinet, which comprises a cabinet body and the door assembly described above, and the door assembly is pivotally installed on the cabinet body.

[0134] According to the storage cabinet of the second aspect embodiment of the present application, by arranging the door assembly described above, the flatness and simplicity of the surface of the door body 100 can be ensured when the door body 100 is in the closed state, while ensuring the convenience of opening and closing the door body 100. At the same time, the user can be prevented from being pinched, and the damage of the driving device can also be avoided.

[0135] In the embodiment of the present application, the storage cabinet can be a refrigerator, a freezer, a wine cabinet, etc. Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
