[0089] like Figures 1 to 21 As shown, a first aspect of the present invention provides a door assembly, including a door body 100, a drive device, a bracket, and a clutch mechanism; wherein, the door body 100 has a handle groove 102; the bracket is hinged to the door body 100 and a cover plate assembly is mounted on the bracket; the clutch mechanism is mounted on the bracket; the drive device is adapted to drive the bracket to switch between a pressed state and a reset state; in the pressed state, the cover plate assembly avoids the handle groove 102, and in the reset state, the cover plate assembly covers the handle groove 102; during the switching between the pressed state and the reset state, the clutch mechanism is adapted to adjust the movement speed of the cover plate assembly.

[0090] According to the door assembly provided in the first aspect embodiment of the present invention, by providing a clutch mechanism on the bracket and adjusting the movement speed of the bracket when switching between the reset state and the pressing state through the clutch mechanism, the bracket can be driven to switch between the reset state and the pressing state more quickly, thereby making the cover assembly hide faster and facilitating the user to quickly engage the handle groove 102 to open the door 100. It also improves the bracket reset process. Due to the clutch mechanism, the working time of the drive device can also be reduced; the switching speed of the bracket can be improved solely by the structural design of the clutch mechanism. The following example uses the door assembly provided in the first aspect embodiment of the present invention in a refrigerator. In this embodiment, there can be one or more doors 100; in other words, the door assembly provided in this embodiment can be applied to a single-door refrigerator or a side-by-side refrigerator.

[0091] A handle groove 102 is formed on the door body 100 for the user to hold. When the handle groove 102 is exposed, the user can hold the handle groove 102 to open the door body 100.

[0092] It should be noted that, in conjunction with the above, Figure 1 and Figure 2 The position of the door assembly on the door body 100 provided in this embodiment of the invention is not limited, but may vary in some specific embodiments.

[0093] When there is only one door body 100, the handle groove 102 can be formed near the edge of the door body 100. That is, when the drive device drives the cover plate assembly to switch to the pressing state, the handle groove 102 set at the edge of the door body 100 can be exposed.

[0094] When there are multiple door bodies 100, the handle groove 102 can be formed at the side edge of any door body 100, or it can be formed at a non-edge position of the door body 100 as needed. Thus, when a user needs to open the current door body 100, the drive device can drive the cover plate assembly on the door body 100, thereby exposing the handle groove 102 on the door body 100, so that the user can easily grab the handle groove 102 to open the door body 100.

[0095] Alternatively, a drive device can be used to drive the cover plate assembly on the door 100, exposing the handle groove 102 on the adjacent door 100, allowing the user to open the adjacent door 100. In other words, the user can flexibly choose to open the corresponding door 100 according to actual door opening needs. That is, when there are multiple doors 100, the handle groove 102 can be set on two adjacent doors 100, thereby facilitating the user to open the desired door 100.

[0096] In this embodiment of the invention, the door assembly further includes a support 144, which is installed on the door body 100. For example, the support 144 can be installed in the foam layer of the door body 100 or detachably installed on the door body 100 by means of bolts, snap-fit, etc. The handle groove 102 described above is formed on the support 144.

[0097] One side of the bracket is hinged to the support 144, and the other side of the bracket is equipped with a cover plate assembly. The bracket is adapted to switch between a pressed state and a reset state. In the pressed state, the cover plate assembly avoids the handle groove 102, and in the reset state, the cover plate assembly covers the handle groove 102.

[0098] As mentioned earlier, when the bracket is in the pressed state, the cover plate assembly mounted on the bracket can avoid the handle groove 102, exposing the handle groove 102. At this time, the user can then hold the handle groove 102 to open the door 100. When the bracket is in the reset state, the cover plate assembly mounted on the bracket can cover the handle groove 102, making the door 100 flat and clean. The pressed state mentioned here refers to the position where the drive device drives the bracket to move the cover plate assembly towards the position where it is retracted to the door 100, and the cover plate assembly exposes the handle groove 102. At this time, the bracket is in the pressed state. The reset state refers to the position where the bracket drives the cover plate assembly from the state of being retracted to the state of being flush with the outer surface of the door 100. At this time, the bracket is in the reset state.

[0099] In this embodiment of the invention, the drive device can be installed in the support 144 or directly on the door 100. The drive device is mainly used to control the switch between the pressing state and the reset state of the bracket.

[0100] According to one embodiment of the present invention, 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 cause the cover plate assembly to move in a direction perpendicular to the door body 100.

[0101] See Figure 2 The first rotating bracket and the second rotating bracket together constitute the bracket in this embodiment of the invention. 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 hinge action of the first rotating bracket and the second rotating bracket.

[0102] The driving device can be connected to either the first rotating bracket or the second rotating bracket, or it can be connected to both simultaneously. Driven by the driving device, the first rotating bracket and / or the second rotating bracket can be rotated, thereby achieving the purpose of moving the cover plate assembly relative to the support 144. In this embodiment of the invention, the first rotating bracket and the second rotating bracket can move the cover plate assembly in a direction perpendicular to the door body 100. It can be understood that the cover plate assembly can translate relative to the door body 100 in a direction perpendicular to the door body 100.

[0103] According to one embodiment of the present invention, the first rotating bracket includes a synchronous shaft 110, a first connecting shaft 112, and a first connecting member 114; the second rotating bracket includes two second connecting shafts 116 and a second connecting member 118. The two ends of the synchronous shaft 110 are hinged to a support 144, the two ends of the first connecting shaft 112 are hinged to a cover plate assembly, and the first connecting member 114 connects the synchronous shaft 110 and the first connecting shaft 112; one of the second connecting shafts 116 is hinged to the support 144 at both ends, the other second connecting shaft 116 is hinged to the cover plate assembly at both ends, and the second connecting member 118 connects the two second connecting shafts 116 and 118.

[0104] In other words, please see Figure 2 Both ends of the synchronous shaft 110 and both ends of one of the second connecting shafts 116 are hinged to the support 144, and both ends of the first connecting shaft 112 and both ends of the other second connecting shaft 116 are hinged to the cover plate assembly. To improve the connection stability between the synchronous shaft 110 and the first connecting shaft 112, a first connecting member 114 is also connected between the synchronous shaft 110 and the first connecting shaft 112, and correspondingly, a second connecting member 118 is connected between the two second connecting shafts 116.

[0105] It should be noted that, in this embodiment of the invention, the synchronous shaft 110 is a major axis, and the cross-section of the synchronous shaft 110 is a polygonal axis. The first connecting shaft 112 can be configured to be the same width as only the first connecting member 114, and the two second connecting shafts 116 can be configured to be the same width as only the second connecting member 118.

[0106] In this embodiment of the invention, the hinge point between the synchronous shaft 110 and the support 144, the hinge point between one of the second connecting shafts 116 and the support 144, the hinge point between the first connecting shaft 112 and the cover plate assembly, and the hinge point between the other second connecting shaft 116 and the cover plate assembly can be connected in sequence to form a parallelogram. Since the hinge points of the synchronous shaft 110 and the support 144, as well as the hinge point of one of the second connecting shafts 116 and the support 144, are all fixed points, and the relative distance between these two hinge points and the inclination angle of the line connecting these two hinge points are also fixed, the distance between the hinge point of the first connecting shaft 112 and the cover plate assembly, and the hinge point of the other second connecting shaft 116 and the cover plate assembly are also equal. The line connecting the hinge point of the first connecting shaft 112 and the cover plate assembly, and the hinge point of the other second connecting shaft 116 and the cover plate assembly, is also parallel to the line connecting the hinge point of the synchronous shaft 110 and the support 144, and the hinge point of one of the second connecting shafts 116 and the support 144. Therefore, the cover plate assembly can translate in a direction perpendicular to the door body 100.

[0107] 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 5 The downward translation is approximately 1 to 3 millimeters, and then the direction is perpendicular to... Figure 5 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 5 The downward translation is approximately 1 to 3 millimeters, and then the direction is perpendicular to... Figure 5 It then moves outwards by a distance of about 1 to 3 millimeters, eventually reaching the position where the handle groove 102 is concealed.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] In this embodiment of the invention, the driving device includes a driving component 124, which is mounted on the door body 100 and connected to a synchronous shaft 110. A transmission shaft sleeve 126 is also connected between the driving component 124 and the synchronous shaft 110. By providing the transmission shaft sleeve 126, the transmission connection between the driving component 124 and the synchronous shaft 110 can be better realized.

[0113] In this embodiment of the invention, a notch 128 is also provided on the transmission shaft sleeve 126, and a lever 130 adapted to the notch 128 is provided on the driving member 124. The width of the notch 128 is greater than the width of the lever 130. The notch 128 can be opened along the circumference of the transmission shaft sleeve 126 at the edge of the transmission shaft sleeve 126. It is understood that the lever 130 can move within the notch 128, and when the lever 130 abuts against the side wall of the notch 128, it can drive the transmission shaft sleeve 126 to move.

[0114] See Figure 9 , Figure 12 , Figure 15 , Figure 18 as well as Figure 21 In this embodiment of the invention, a first sidewall 129 and a second sidewall 131 are provided on opposite sides of the notch 128. The first sidewall 129 and the second sidewall 131 can be parallel or angled.

[0115] When the bracket switches from the reset state to the pressing state, the lever 130 abuts against the first side wall 129 to drive the transmission shaft sleeve 126 to move. After the lever 130 abuts against the first side wall 129, it can apply force to the first side wall 129 to drive the synchronous shaft 110 to rotate, thereby enabling the synchronous shaft 110 to drive the bracket to switch from the reset state to the pressing state.

[0116] When the bracket moves to the reset 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 where it is in contact with the second side wall 131. With this setting, when the drive component 124 reverses, it can directly form an abutment relationship with the second side wall 131 to apply force to the second side wall 131.

[0117] Similarly, when the bracket switches from the pressed state to the reset state, the lever 130 abuts against the second side wall 131 to drive the transmission shaft sleeve 126 to move. After the lever 130 abuts against the second side wall 131, it can apply force to the second side wall 131 to drive the synchronous shaft 110 to rotate, thereby enabling the synchronous shaft 110 to drive the bracket to switch from the pressed state to the reset state.

[0118] 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.

[0119] Understandably, when the cover assembly is in the reset state, the lever 130 and the notch 128 are in the same position as... Figure 9 The state shown; when the cover plate 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 12 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 15 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 18 The state shown; when the cover 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 21 The state shown; when the cover plate assembly is in the reset state, the lever 130 and the notch 128 are in the position shown. Figure 9 The state shown.

[0120] Please continue reading Figure 3In 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] When the door 100 switches from the open state to the closed state, the detection element can detect the movement of the door 100 to generate a detection signal indicating that the door 100 is closed; or, after the user leaves, the detection element can detect that the person has left the vicinity of the door 100 to generate a detection signal indicating that the door 100 can be closed. When the drive device receives the detection signal, the drive device can switch the first rotating bracket and / or the second rotating bracket from the pressed state to the reset state.

[0125] It should be noted that, in addition to the sensors for detecting human distance (such as infrared sensors and laser sensors) mentioned above, the detection device can also be a sensor for detecting human biometrics, such as facial recognition and voice recognition devices, or a pressure sensor. When a user touches a certain area of ​​the door 100, a detection signal is generated. In other words, the present invention does not impose specific restrictions on the type of detection device and the excitation method, as long as it can determine the user's opening and closing needs.

[0126] In this embodiment of the invention, the running time of the motor can also be set to automatically stop after running for a certain number of seconds. For example, when the motor drives the first rotating bracket to switch from the reset state to the pressing state and encounters a foreign object stuck, the motor will automatically stop after running for a certain number of seconds. After the foreign object is removed, the cover plate body 134 can be manually pressed to make the bracket move to the pressing state. This can effectively avoid the motor being damaged due to large torque.

[0127] Furthermore, by setting the motor's running time to a preset duration, the motor can automatically stop after the preset time, eliminating the need for additional sensors and further reducing design and manufacturing costs. Additionally, users can keep the bracket in the pressed state according to their actual needs, allowing for convenient opening of the door 100 at any time. Correspondingly, keeping the bracket in the pressed state can be achieved by controlling the motor.

[0128] The clutch mechanism provided in the embodiments of the present invention will be described below:

[0129] like Figure 3 As shown, according to an embodiment of the present invention, the clutch mechanism includes a first clutch bushing 104, a second clutch bushing 106, and an elastic member 108; wherein, the first clutch bushing 104 is mounted on the synchronous shaft 110; the second clutch bushing 106 is mounted on the synchronous shaft 110 via a mounting bushing 107; the elastic member 108 is sleeved on the synchronous shaft 110 and abuts against the side of the second clutch bushing 106 opposite to the first clutch bushing 104 and between the second clutch bushing 106 and the mounting bushing 107; one of the opposing sides of the first clutch bushing 104 and the second clutch bushing 106 is provided with a first plane 138 and a first inclined plane 140 connected to each other, and the other is provided with a second plane 142; when the first plane 138 and the second plane 142 abut against each other, the elastic member 108 is in a compressed state; when the first plane 138 and the second plane 142 are separated from each other, the elastic member 108 is in a reset process.

[0130] In this embodiment of the invention, a first clutch bushing 104 can be fixedly mounted on the synchronous shaft 110, and a second clutch bushing 106 can be rotatably mounted on the bushing. It should be noted that the first clutch bushing 104 being fixedly mounted on the synchronous shaft 110 means that the first clutch bushing 104 can rotate synchronously with the synchronous shaft 110, but can slide axially relative to the synchronous shaft 110. An elastic element 108 is provided between the side of the second clutch bushing 106 opposite to the first clutch bushing 104 and the mounting bushing 107. One end of the elastic element 108 is fixed in axial position relative to the synchronous shaft 110, and the other end abuts against the side of the second clutch bushing 106 opposite to the first clutch bushing 104. The elastic element 108 can be a spring, torsion spring, or the like. In this way, under the elastic force of the elastic element 108, the second clutch bushing 106 can always be pressed tightly against the first clutch bushing 104, effectively preventing the support from rotating under its own weight.

[0131] The following describes several different mating methods between the first clutch bushing 104 and the second clutch bushing 106:

[0132] A first inclined surface 140 and a second inclined surface 141 are provided on the side of the first clutch bushing 104 facing the second clutch bushing 106, and a first plane 138 is provided between the first inclined surface 140 and the second inclined surface 141.

[0133] Method 1:

[0134] In this type of engagement, the transition surface provided on the second clutch bushing 106 includes the second plane 142.

[0135] See also Figure 4 , Figure 8 , Figure 11 , Figure 14 , Figure 17 as well as Figure 20 When the first plane 138 and the second plane 142 come into contact with each other, the elastic element 108 is in a compressed state. That is, the first clutch bushing 104 and the second clutch bushing 106 can press against each other under the action of the elastic restoring force of the elastic element 108.

[0136] When the drive member 124 drives the second clutch bushing 106 to move, the second clutch bushing 106 rotates relative to the first clutch bushing 104, and the first plane 138 and the second plane 142 come into contact with each other. At this time, the elastic member 108 is in a compressed state. Under these circumstances, the friction between the first clutch bushing 104 and the second clutch bushing 106 increases, and the cover plate assembly will not move under its own weight.

[0137] When the critical point between the first plane 138 and the second plane 142 is crossed, the contact between the first inclined plane 140 and the second plane 142 is released. At this time, the elastic element 108 switches from the compressed state to the original state, and the friction between the second clutch bushing 106 and the first clutch bushing 104 is reduced, thereby enabling the bracket to quickly switch to the pressing state, and thus enabling the cover assembly to quickly switch to the pressing state, making it convenient for the user to open the door 100.

[0138] When the driving member 124 drives the second clutch bushing 106 to reverse, the second clutch bushing 106 rotates relative to the first clutch bushing 104. When it crosses the critical point between the first plane 138 and the second plane 142, the contact relationship between the second inclined surface 141 and the second plane 142 is released. At this time, the elastic member 108 switches from the compressed state to the original state, and the friction between the second clutch bushing 106 and the first clutch bushing 104 decreases, thereby enabling the bracket to quickly switch to the reset state, and thus enabling the cover plate assembly to quickly switch to the reset state.

[0139] It is understandable that in the above process, the first clutch bushing 104 and the second clutch bushing 106 are first rotated relative to each other by the drive of the drive component 124, and then the elastic restoring force of the elastic component 108 accelerates the relative rotation of the first clutch bushing 104 and the second clutch bushing 106, thereby enabling the cover plate assembly to quickly switch to the pressing state or the reset state.

[0140] Method 2:

[0141] In this engagement configuration, the transition surface provided on the second clutch bushing 106 includes a first inclined surface 140, a second flat surface 142, and a second inclined surface 141 connected in sequence.

[0142] When the drive member 124 drives the second clutch bushing 106 to move, the second clutch bushing 106 rotates relative to the first clutch bushing 104, and the first plane 138 and the second plane 142 come into contact with each other. At this time, the elastic member 108 is in a compressed state. Under these circumstances, the friction between the first clutch bushing 104 and the second clutch bushing 106 increases, and the cover plate assembly will not move under its own weight.

[0143] When the first plane 138 and the second plane 142 are crossed, the first inclined surface 140 on the first clutch bushing 104 and the first inclined surface 140 on the second clutch bushing 106 come into contact with each other. At this time, the elastic element 108 switches from the compressed state to the original state, and the friction between the second clutch bushing 106 and the first clutch bushing 104 decreases, thereby enabling the bracket to quickly switch to the pressing state, and thus enabling the cover assembly to quickly switch to the pressing state, making it convenient for the user to open the door 100.

[0144] When the drive member 124 drives the second clutch bushing 106 to reverse, the second clutch bushing 106 rotates relative to the first clutch bushing 104. When it passes the critical point between the first plane 138 and the second plane 142, the second inclined surface 141 on the first clutch bushing 104 and the second inclined surface 141 on the second clutch bushing 106 come into contact with each other. At this time, the elastic member 108 switches from the compressed state to the original state, and the friction between the second clutch bushing 106 and the first clutch bushing 104 decreases, thereby enabling the bracket to quickly switch to the reset state, and thus enabling the cover plate assembly to quickly switch to the reset state.

[0145] Method 3:

[0146] In this type of engagement, the transition surface provided on the second clutch bushing 106 includes a first inclined surface 140.

[0147] When the drive member 124 drives the second clutch bushing 106 to move, the second clutch bushing 106 rotates relative to the first clutch bushing 104. The edge of the first inclined surface 140 on the second clutch bushing 106 comes into contact with the first plane 138. At this time, the elastic member 108 is in a compressed state. Under these circumstances, the friction between the first clutch bushing 104 and the second clutch bushing 106 increases, and the cover plate assembly will not move under its own weight.

[0148] When the edge of the first inclined surface 140 on the second clutch bushing 106 crosses the critical point between the first plane 138 and the edge of the first inclined surface 140 on the second clutch bushing 106, the first inclined surface 140 on the second clutch bushing 106 and the first inclined surface 140 on the first clutch bushing 104 come into contact with each other, the elastic element 108 switches from the compressed state to the original state, the friction between the second clutch bushing 106 and the first clutch bushing 104 decreases, thereby enabling the bracket to quickly switch to the pressing state, and thus enabling the cover assembly to quickly switch to the pressing state, making it convenient for the user to open the door 100.

[0149] When the drive member 124 drives the second clutch bushing 106 to reverse, the second clutch bushing 106 rotates relative to the first clutch bushing 104. When it passes the critical point between the edge of the first inclined surface 140 on the first clutch bushing 104 and the second plane 142, the contact between the first inclined surface 140 on the first clutch bushing 104 and the second plane 142 is released, the elastic member 108 switches from the compressed state to the original state, the friction between the second clutch bushing 106 and the first clutch bushing 104 decreases, thereby enabling the bracket to quickly switch to the reset state, and thus enabling the cover plate assembly to quickly switch to the reset state.

[0150] Method 4:

[0151] In this type of engagement, the transition surface provided on the second clutch bushing 106 includes a first inclined surface 140 and a second inclined surface 141 that are connected to each other.

[0152] When the drive member 124 drives the second clutch bushing 106 to move, the second clutch bushing 106 rotates relative to the first clutch bushing 104. The connection position of the first inclined surface 140 and the second inclined surface 141 on the second clutch bushing 106 comes into contact with the first plane 138. At this time, the elastic member 108 is in a compressed state. Under these circumstances, the friction between the first clutch bushing 104 and the second clutch bushing 106 increases, and the cover plate assembly will not move under its own weight.

[0153] When the first inclined surface 140 on the second clutch bushing 106 and the first inclined surface 141 are connected at the critical point with the first plane 138, the first inclined surface 140 on the second clutch bushing 106 and the first inclined surface 140 on the first clutch bushing 104 come into contact with each other, the elastic element 108 switches from the compressed state to the original state, the friction between the second clutch bushing 106 and the first clutch bushing 104 decreases, thereby enabling the bracket to quickly switch to the pressing state, and thus enabling the cover assembly to quickly switch to the pressing state, making it convenient for the user to open the door 100.

[0154] When the drive member 124 drives the second clutch bushing 106 to reverse, the second clutch bushing 106 rotates relative to the first clutch bushing 104. After passing the critical point between the connection position of the first inclined surface 140 and the second inclined surface 141 on the second clutch bushing 106 and the first plane 138, the abutment relationship between the connection position of the first inclined surface 140 and the second inclined surface 141 on the second clutch bushing 106 and the first plane 138 is released. The second inclined surface 141 on the second clutch bushing 106 contacts the second inclined surface 141 on the first clutch bushing 104. The elastic member 108 switches from the compressed state to the original state. The friction between the second clutch bushing 106 and the first clutch bushing 104 decreases, thereby enabling the bracket to quickly switch to the reset state, and thus enabling the cover plate assembly to quickly switch to the reset state.

[0155] Method 5:

[0156] In this type of engagement, the transition surface provided on the second clutch bushing 106 includes a first inclined surface 140 and a second flat surface 142 that are interconnected.

[0157] When the drive member 124 drives the second clutch bushing 106 to move, the second clutch bushing 106 rotates relative to the first clutch bushing 104, and the second plane 142 and the first plane 138 come into contact with each other. At this time, the elastic member 108 is in a compressed state. Under these circumstances, the friction between the first clutch bushing 104 and the second clutch bushing 106 increases, and the cover plate assembly will not move under its own weight.

[0158] When the critical point between the second plane 142 and the first plane 138 is crossed, the first inclined surface 140 on the second clutch bushing 106 and the first inclined surface 140 on the first clutch bushing 104 come into contact with each other, the elastic element 108 switches from the compressed state to the original state, the friction between the second clutch bushing 106 and the first clutch bushing 104 decreases, thereby enabling the bracket to quickly switch to the pressing state, and thus enabling the cover assembly to quickly switch to the pressing state, making it convenient for the user to open the door 100.

[0159] When the drive member 124 drives the second clutch bushing 106 to reverse, the second clutch bushing 106 rotates relative to the first clutch bushing 104. When it crosses the critical point between the second plane 142 and the first plane 138, the second plane and the first plane separate from each other, the elastic member 108 switches from the compressed state to the original state, the friction between the second clutch bushing 106 and the first clutch bushing 104 decreases, thereby enabling the bracket to quickly switch to the reset state, and thus enabling the cover plate assembly to quickly switch to the reset state.

[0160] Additionally, it should be noted that when the synchronous shaft 110 encounters a foreign object and gets stuck during forward or reverse rotation, the transmission connection between the first clutch bushing 104 and the second clutch bushing 106 encounters resistance. At this time, although the spring can still hold the second clutch bushing 106 against the first clutch bushing 104, the resistance is much greater than the spring's elastic support force, causing the rotational connection between the first clutch bushing 104 and the second clutch bushing 106 to become unstable. That is, the drive shaft no longer moves synchronously with the second clutch bushing 106; the motor only drives the first clutch bushing 104 to idle, and the synchronous shaft 110 no longer rotates.

[0161] When the foreign object is removed, the second clutch bushing 106, under the elastic support force of the elastic element 108, re-engages with the first clutch bushing 104, and at this time the synchronous shaft 110 can continue to transmit power to the motor.

[0162] When a power outage occurs, the motor stops. If the cover assembly is in the reset state, the user can directly press the cover assembly to change it from the reset state to the pressed state. Since the pressure applied by the user to the cover assembly is much greater than the elastic force of the elastic element 108 between the first clutch bushing 104 and the second clutch bushing 106, the user can still hold the exposed handle groove 102 to open the door 100.

[0163] It is understandable that, in this embodiment of the invention, due to reasons such as component dimensional accuracy or assembly, there will be a certain gap between the motor output shaft and the second clutch bushing 106. When the motor starts to rotate, because of the gap between the motor output shaft and the second clutch bushing 106, the cover assembly cannot move under the action of the motor for a short time. The bracket will move a certain distance towards the inside of the door 100 under the action of gravity until the motor engages with the second clutch bushing 106, at which point the bracket will continue to move under the drive of the motor. Because the movement of the bracket under the action of gravity does not match the speed of the motor drive, the movement process is not smooth. With the addition of the clutch mechanism, the frictional torque generated when the synchronous shaft 110 drives the first clutch bushing 104 and the second clutch bushing 106 to rotate is greater than or equal to the torque generated by the gravity of the cover plate assembly. When the motor starts to rotate, the cover plate assembly remains stationary under the frictional torque until the motor engages with the second clutch bushing 106. The cover plate assembly then starts to move under the drive of the motor, thus ensuring that the movement speed of the cover plate assembly is more stable and the entire movement process is smoother.

[0164] It should be noted that the drive component 124 is connected to the end of the synchronous shaft 110 facing the second clutch bushing 106. With this configuration, the second clutch bushing 106 can be driven to move relative to the first clutch bushing 104.

[0165] A second aspect of the present invention provides a storage cabinet, including a cabinet body and the aforementioned door assembly, the door assembly being pivotally mounted on the cabinet body.

[0166] According to a second aspect embodiment of the present invention, the locker, by providing the aforementioned door assembly, ensures convenient opening and closing of the door 100, while also maintaining a smooth and clean surface on the door 100 when it is closed. It also prevents injury to the user and damage to the drive mechanism.

[0167] In this embodiment of the invention, the storage cabinet can be a refrigerator, freezer, wine cabinet, etc. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
