Description

Technical Field

[0001] This invention relates to the field of storage equipment technology, and in particular to a door assembly, a storage cabinet, and a control method for the door assembly. Background Technology

[0002] In related technologies, concealed handle structures have emerged to achieve handle-free cabinet surfaces. Taking refrigerators as an example, concealed handles are mostly hinged to the door via a bracket. When the motor drives the bracket, the handle can be hidden. However, due to factors such as component dimensional accuracy or assembly issues, there are gaps between the motor and the coupling or between the motor and the bushing. Simultaneously, the bracket will sway to a certain extent under its own weight, causing an inaccurate match between the bracket's movement and the motor's drive speed, resulting in an unsmooth movement of the bracket. Furthermore, since the motor's torque is constant, the handle movement is slow, failing to meet the demand for quick door opening. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in related technologies. To this end, this invention proposes a door assembly that can improve the movement stability of the support and accelerate the opening process of the handle, making it more convenient for users.

[0004] The present invention also proposes a storage cabinet.

[0005] The present invention also proposes a control method for a door assembly.

[0006] The present invention also proposes a control device for a door assembly.

[0007] A first aspect of the present invention provides a gate assembly, comprising:

[0008] The door body has a handle groove.

[0009] Drive unit;

[0010] A bracket, hinged to the door body, and a cover plate assembly is mounted on the bracket;

[0011] The clutch mechanism is mounted on the bracket;

[0012] The drive device is adapted to drive the bracket to switch between a pressing position and a reset position; in the pressing position, the cover plate assembly avoids the handle groove, and in the reset position, the cover plate assembly covers the handle groove; during the switching between the pressing position and the reset position, the clutch mechanism is adapted to adjust the movement speed of the cover plate assembly and compensate for the rotational clearance between the drive device and the bracket.

[0013] According to the door assembly provided in the first aspect of the present invention, by providing a clutch mechanism on the bracket and adjusting the movement speed of the bracket when switching from the reset position to the pressing position through the clutch mechanism, the bracket can be driven to switch from the reset position to the pressing position more quickly, thereby causing the cover plate assembly to move quickly to expose the handle groove, making it convenient for the user to quickly engage the handle groove to open the door. The clutch mechanism compensates for the rotational clearance between the drive device and the bracket, enabling the clutch mechanism to overcome the torque generated by the bracket due to its own weight. When the drive device and the bracket are engaged, the torque applied to the bracket by the drive device can overcome the resistance of the clutch mechanism, thereby driving the bracket to switch between the pressing position and the reset position, thus achieving smooth drive of the bracket by the drive device. Due to the clutch mechanism, the working time of the drive device can also be reduced, and the switching speed of the bracket can be improved solely by the structural design of the clutch mechanism.

[0014] According to one embodiment of the present invention, the clutch mechanism includes:

[0015] The first clutch bushing is fixed to the bracket;

[0016] The second clutch bushing is adapted to be mounted on the bracket by means of a mounting bushing;

[0017] One of the opposing sides of the first clutch bushing and the second clutch bushing is provided with an inclined acceleration surface and an abutment surface that are connected to each other, and the other is provided with a transition surface for cooperating with the inclined acceleration surface and the abutment surface;

[0018] An elastic element is installed on the bracket, and the elastic element is adapted to abut against the side of the second clutch bushing opposite to the first clutch bushing and between the mounting bushing;

[0019] When the inclined acceleration surface and the transition surface are engaged, the elastic element is in the process of resetting;

[0020] When the abutting plane and the transition surface are engaged, the elastic element is in a compressed state.

[0021] According to one embodiment of the present invention, the support includes:

[0022] A first rotating bracket, one side of which is hinged to the door body, and the other side of which is hinged to the cover plate assembly;

[0023] The second rotating bracket has one side hinged to the door body and the other side hinged to the cover plate assembly;

[0024] The clutch mechanism is mounted on the first rotating bracket and / or the second rotating bracket;

[0025] The drive device is adapted to drive the first rotating bracket and / or the second rotating bracket on which the clutch mechanism is mounted, so that the cover plate assembly moves in a direction perpendicular to the door body.

[0026] According to one embodiment of the present invention, the first rotating support includes:

[0027] A synchronous shaft, the two ends of which are hinged to the door body;

[0028] A first connecting shaft, the two ends of which are hinged to the cover plate assembly;

[0029] A first connector is connected between the synchronous shaft and the first connecting shaft;

[0030] The second rotating support includes:

[0031] Two second connecting shafts, one of which is hinged at both ends to the door body, and the other of which is hinged at both ends to the cover plate assembly;

[0032] A second connector is connected between the two second connecting shafts;

[0033] The clutch mechanism is mounted on the synchronous shaft.

[0034] According to one embodiment of the present invention, the driving device includes a driving member and a transmission shaft sleeve disposed between the driving member and the synchronous shaft. The transmission shaft sleeve has a notch, and the driving member is provided with a lever adapted to the notch. The width of the notch is greater than the width of the lever.

[0035] According to one embodiment of the present invention, a first sidewall and a second sidewall are provided on opposite sides of the notch;

[0036] From the reset position to the pressing position, the lever is adapted to abut against the first sidewall; in the reset position, the driving member is adapted to drive the lever to reverse so that the lever fits against the second sidewall.

[0037] From the pressed position to the reset position, the lever is adapted to abut against the second side wall. In the pressed position, the driving member is adapted to drive the lever to move so that the lever fits against the first side wall.

[0038] According to one embodiment of the present invention, a detection element is further included, which is mounted on the door and / or bracket to generate a detection signal for detecting vital signs, and the driving device is adapted to drive the bracket to switch between a pressed position and a reset position based on the detection signal.

[0039] 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.

[0040] According to the second aspect of the present invention, the locker provided with the above-mentioned door assembly can improve the speed at which the cover assembly switches between the pressing position and the reset position, and can also improve the movement stability of the cover assembly, making the cover assembly more stable during operation.

[0041] A third aspect of the present invention provides a control method based on the above-described door assembly, comprising:

[0042] It is determined that the cover plate assembly is in the process of switching from the pressed position to the reset position;

[0043] The drive device is controlled to switch the bracket between the pressing position and the intermediate position;

[0044] The drive device is controlled to move the bracket from the pressing position or the intermediate position to the reset position;

[0045] The intermediate position is located between the pressing position and the reset position.

[0046] According to the control method for a door assembly provided in the third aspect of the present invention, during the process of switching the cover assembly from the pressing position to the reset position, the control bracket switches between the current pressing position and the intermediate position, so that the cover assembly does not move directly to the reset position. This avoids the cover assembly from pinching the user's hand during the reset process, and also avoids overload of the drive device caused by foreign objects being stuck.

[0047] According to one embodiment of the present invention, it further includes:

[0048] The cover plate assembly is switched to the reset position, and the drive device is stalled for a preset time.

[0050] The determination module is used to determine whether the cover plate assembly is in the process of switching from the pressed position to the reset position;

[0051] The first control module is used to control the drive device to switch the bracket between the pressing position and the intermediate position.

[0052] The second control module is used to control the drive device to switch the bracket from the pressing position or the intermediate position to the reset position;

[0053] The intermediate position is located between the pressing position and the reset position.

[0054] A fifth aspect of the present invention provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the control method described above.

[0055] A sixth aspect of the present invention provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the control method described above.

[0056] A seventh aspect of the present invention provides a computer program product, including a computer program that, when executed by a processor, implements the control method described above.

[0057] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0058] According to the door assembly provided in the first aspect of the present invention, by providing a clutch mechanism on the bracket and adjusting the movement speed of the bracket when switching from the reset position to the pressing position through the clutch mechanism, the bracket can be driven to switch from the reset position to the pressing position more quickly, thereby causing the cover plate assembly to move quickly to expose the handle groove, making it convenient for the user to quickly engage the handle groove to open the door. The clutch mechanism compensates for the rotational clearance between the drive device and the bracket, enabling the clutch mechanism to overcome the torque generated by the bracket due to its own weight. When the drive device and the bracket are engaged, the torque applied to the bracket by the drive device can overcome the resistance of the clutch mechanism, thereby driving the bracket to switch between the pressing position and the reset position, thus achieving smooth drive of the bracket by the drive device. Due to the clutch mechanism, the working time of the drive device can also be reduced, and the switching speed of the bracket can be improved solely by the structural design of the clutch mechanism.

[0059] Furthermore, according to the second aspect embodiment of the present invention, by providing the above-mentioned door assembly, the speed at which the cover assembly switches between the pressing position and the reset position can be increased, and the movement stability of the cover assembly can also be improved, making the cover assembly more stable during operation.

[0060] Furthermore, according to the control method for a door assembly provided in the third aspect embodiment of the present invention, by controlling the bracket to switch between the current pressing position and the intermediate position during the process of the cover assembly switching from the pressing position to the reset position, the cover assembly will not move directly to the reset position. This avoids the cover assembly from pinching the user's hand during the reset process, and also avoids overload of the drive device caused by foreign objects being stuck.

[0061] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0094] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0099] like Figures 1 to 26 As shown, the first embodiment of the present invention provides a door assembly, including a door body 500, a drive device, a bracket, and a clutch mechanism; wherein, the door body 500 has a handle groove 502; the bracket is hinged to the door body 500 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 pressing position and a reset position; in the pressing position, the cover plate assembly avoids the handle groove 502, and in the reset position, the cover plate assembly covers the handle groove 502; during the switching between the pressing position and the reset position, the clutch mechanism is adapted to adjust the movement speed of the cover plate assembly and compensate for the rotational clearance between the drive device and the bracket.

[0100] According to the door assembly provided in the first aspect of the present invention, by providing a clutch mechanism on the bracket and adjusting the movement speed of the bracket when switching from the reset position to the pressing position through the clutch mechanism, the bracket can be driven to switch from the reset position to the pressing position more quickly, thereby causing the cover plate assembly to move quickly to expose the handle groove 502, making it convenient for the user to quickly engage the handle groove 502 to open the door 500. By compensating for the rotational clearance between the drive device and the bracket through the clutch mechanism, the clutch mechanism can overcome the torque generated by the bracket due to its own weight. When the drive device and the bracket are engaged, the torque applied to the bracket by the drive device can overcome the resistance of the clutch mechanism, thereby driving the bracket to switch between the pressing position and the reset position, thus achieving smooth drive of the bracket by the drive device. Due to the provision of the clutch mechanism, the working time of the drive device can also be reduced, and the switching speed of the bracket can be improved solely by the structural design of the clutch mechanism.

[0101] The following example uses the door assembly provided in the first aspect of the present invention to be applied to a refrigerator. In the embodiment of the present invention, the door body 500 can be one or more. In other words, the door assembly provided in the embodiment of the present invention can be applied to a single-door refrigerator or a double-door refrigerator.

[0102] A handle groove 502 is formed on the door body 500 for the user to hold. When the handle groove 502 is exposed, the user can hold the handle groove 502 to open the door body 500.

[0103] 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 500 provided in this embodiment of the invention is not limited, but may vary in some specific embodiments.

[0104] When there is only one door body 500, the handle groove 502 can be formed near the edge of the door body 500. That is, when the drive device drives the cover plate assembly to switch to the pressing position, the handle groove 502 set at the edge of the door body 500 can be exposed.

[0105] When there are multiple door bodies 500, the handle groove 502 can be formed at the side edge of any door body 500, or it can be formed at a non-edge position of the door body 500 as needed. Thus, when a user needs to open the current door body 500, the drive device can drive the cover plate assembly on the door body 500, thereby exposing the handle groove 502 on the door body 500, so that the user can easily grab the handle groove 502 to open the door body 500.

[0106] Alternatively, a drive device can be used to drive the cover plate assembly on the door 500, exposing the handle groove 502 on the adjacent door 500, allowing the user to open the adjacent door 500. In other words, the user can flexibly choose to open the appropriate door 500 according to actual door opening needs. That is, when there are multiple doors 500, the handle groove 502 can be set on two adjacent doors 500, thus facilitating the user to open the desired door 500.

[0107] In this embodiment of the invention, the door assembly further includes a support, which is installed on the door body 500. For example, the support can be installed in the foam layer of the door body 500 or detachably installed on the door body 500 by means of bolts, snap-fit, etc. The handle groove 502 described above is formed on the support.

[0108] One side of the bracket is hinged to the support, and the other side of the bracket is equipped with a cover plate assembly. The bracket is adapted to switch between a pressing position and a reset position. In the pressing position, the cover plate assembly avoids the handle groove 502, and in the reset position, the cover plate assembly covers the handle groove 502.

[0109] As mentioned earlier, when the bracket is in the pressed position, the cover plate assembly mounted on the bracket can avoid the handle groove 502, exposing the handle groove 502. At this time, the user can then grab the handle groove 502 to open the door 500. When the bracket is in the reset position, the cover plate assembly mounted on the bracket can cover the handle groove 502, making the door 500 in a flat and clean state. The pressed position 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 into the door 500, and the cover plate assembly exposes the handle groove 502. At this time, the bracket is in the pressed position. The reset position refers to the position where the bracket drives the cover plate assembly from the state of being retracted into the door 500 to the state of being flush with the outer surface of the door 500. At this time, the bracket is in the reset position.

[0110] In this embodiment of the invention, the drive device can be installed in the support or directly on the door 500. The drive device is mainly used to control the bracket to switch between the pressing position and the reset position.

[0111] 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 a support, and the other side of the first rotating bracket is hinged to a cover plate assembly; one side of the second rotating bracket is hinged to the support, 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 500.

[0112] See Figure 3The 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, 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 under the hinge action of the first rotating bracket and the second rotating bracket.

[0113] 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. In this embodiment of the invention, 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 500. It can be understood that the cover plate assembly can translate relative to the door body 500 in a direction perpendicular to the door body 500.

[0114] According to one embodiment of the present invention, a first rotating bracket includes a synchronous shaft 518, a first connecting shaft 520, and a first connecting member 521; a second rotating bracket includes two second connecting shafts 522 and a second connecting member 524. The two ends of the synchronous shaft 518 are hinged to a support, the two ends of the first connecting shaft 520 are hinged to a cover plate assembly, and the first connecting member 521 connects the synchronous shaft 518 and the first connecting shaft 520; one of the second connecting shafts 522 is hinged to the support at both ends, the other second connecting shaft 522 is hinged to the cover plate assembly at both ends, and the second connecting member 524 connects the two second connecting shafts 522 and the first connecting shaft 524.

[0115] In other words, please see Figure 3 Both ends of the synchronous shaft 518 and both ends of one of the second connecting shafts 522 are hinged to the support, and both ends of the first connecting shaft 520 and both ends of the other second connecting shaft 522 are hinged to the cover plate assembly. To improve the connection stability between the synchronous shaft 518 and the first connecting shaft 520, a first connecting member 521 is also connected between the synchronous shaft 518 and the first connecting shaft 520, and correspondingly, a second connecting member 524 is connected between the two second connecting shafts 522.

[0116] It should be noted that, in this embodiment of the invention, the synchronous shaft 518 is a major axis, and the cross-section of the synchronous shaft 518 is a polygonal axis. The first connecting shaft 520 can be configured to be the same width as only the first connecting member 521, and the two second connecting shafts 522 can be configured to be the same width as only the second connecting member 524.

[0117] In this embodiment of the invention, the hinge point between the synchronous shaft 518 and the support, the hinge point between one of the second connecting shafts 522 and the support, the hinge point between the first connecting shaft 520 and the cover plate assembly, and the hinge point between the other second connecting shaft 522 and the cover plate assembly can be connected in sequence to form a parallelogram. Since the hinge points of the synchronous shaft 518 and the support, as well as the hinge points of one of the second connecting shafts 522 and the support, are all fixed points, the relative distance between these two hinge points and the inclination angle of the line connecting these two hinge points are also fixed. Therefore, the distance between the hinge points of the first connecting shaft 520 and the cover plate assembly, and the hinge points of the other second connecting shaft 522 and the cover plate assembly, are also equal. The line connecting the hinge points of the first connecting shaft 520 and the cover plate assembly, and the hinge points of the other second connecting shaft 522 and the cover plate assembly, is also parallel to the line connecting the hinge points of the synchronous shaft 518 and the support, and the hinge points of the other second connecting shaft 522 and the support. Therefore, the cover plate assembly can translate in a direction perpendicular to the door body 500.

[0118] It should be noted that during the movement of the cover assembly from the position of obscuring the handle groove 502 to the position of avoiding the handle groove 502, the cover assembly first moves towards... Figure 21 The downward translation is shown as a distance of approximately 1 to 3 millimeters, and then... Figure 2 The cover assembly moves to the right, eventually reaching the position that avoids the handle groove 502. Similarly, during the movement of the cover assembly from the position that avoids the handle groove 502 to the position that covers the handle groove 502, the cover assembly first moves towards the right. Figure 25 The downward translation is shown as a distance of approximately 1 to 3 millimeters, and then... Figure 25 The left side moves and eventually moves to the position of shielding the handle groove 502.

[0119] To limit the relative position between the first connecting shaft 520 and the first connecting member 521, first limiting members are provided at both ends of the first connecting shaft 520. The first limiting members can be limiting pins or the like. Similarly, to limit the relative position between the second connecting shaft 522 and the second connecting member 524, second limiting members are provided at both ends of the second connecting shaft 522. The second limiting members can be limiting pins or the like.

[0120] In some other embodiments, the first rotating bracket and the second rotating bracket can 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 518, the first connecting shaft 520, the second connecting shaft 522 and the corresponding connecting parts, but instead use an integrally formed rectangular frame structure to replace the above-mentioned components.

[0121] According to one embodiment of the present invention, the cover plate assembly includes a cover plate base and a cover plate body; both ends of the first connecting shaft 520 and the other end of the first connecting shaft 520 are respectively hinged to the cover plate base; the cover plate body is mounted on the cover plate base.

[0122] See also Figure 3 The first connecting shaft 520 and the other second connecting shaft 522 are hinged to the cover plate base at both ends. A cover plate body is also installed on the cover plate base, and the cover plate body and the cover plate base can be fixed together by means of adhesive, snap-fit, etc. In other words, when the drive 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 and the cover plate body to switch between the position of avoiding the handle groove 502 and the position of covering the handle groove 502. In addition, the cover plate body can be made of the same material as the outer surface of the door body 500, which can further improve the appearance consistency of the outer surface of the door body 500.

[0123] In this embodiment of the invention, the driving device includes a driving component 504, which is mounted on the door body 500 and connected to a synchronous shaft 518. A transmission shaft sleeve 528 is also connected between the driving component 504 and the synchronous shaft 518. By providing the transmission shaft sleeve 528, the transmission connection between the driving component 504 and the synchronous shaft 518 can be better realized.

[0124] In this embodiment of the invention, a notch 530 is also provided on the transmission shaft sleeve 528, and a lever 532 adapted to the notch 530 is provided on the driving member 504. The width of the notch 530 is greater than the width of the lever 532. The notch 530 can be opened along the circumference of the transmission shaft sleeve 528 at the edge of the transmission shaft sleeve 528. It is understood that the lever 532 can move within the notch 530. When the lever 532 abuts against the side wall of the notch 530, it can drive the transmission shaft sleeve 528 to move.

[0125] See Figure 8 , Figure 11 , Figure 14 , Figure 17 as well as Figure 20 In this embodiment of the invention, a first sidewall 534 and a second sidewall 536 are provided on opposite sides of the notch 530. The first sidewall 534 and the second sidewall 536 can be parallel or angled.

[0126] When the bracket switches from the reset position to the pressing position, the lever 532 abuts against the first side wall 534 to drive the transmission shaft sleeve 528 to move. After the lever 532 abuts against the first side wall 534, it can apply force to the first side wall 534 to drive the synchronous shaft 518 to rotate, thereby enabling the synchronous shaft 518 to drive the bracket to switch from the reset position to the pressing position.

[0127] When the bracket moves to the reset position, in order to ensure that the drive component 504 can promptly drive the transmission shaft sleeve 528 to reverse when it reverses, the drive component 504 will reverse appropriately to drive the lever 532 to reverse. The lever 532 will stop when it reverses to the position where it is in contact with the second side wall 536. With this setting, when the drive component 504 reverses, it can directly form an abutment relationship with the second side wall 536 to apply force to the second side wall 536.

[0128] Similarly, when the bracket switches from the pressing position to the reset position, the lever 532 abuts against the second side wall 536 to drive the transmission shaft sleeve 528 to move. After the lever 532 abuts against the second side wall 536, it can apply force to the second side wall 536 to drive the synchronous shaft 518 to rotate, thereby enabling the synchronous shaft 518 to drive the bracket to switch from the pressing position to the reset position.

[0129] When the bracket moves to the pressing position, in order to ensure that the drive component 504 can promptly drive the transmission shaft sleeve 528 to reverse when it reverses, the drive component 504 will reverse appropriately to drive the lever 532 to reverse. The lever 532 will stop when it reverses to the position where it is in contact with the first side wall 534. With this setting, when the drive component 504 reverses, it can directly form an abutment relationship with the first side wall 534 to apply force to the first side wall 534.

[0130] Understandably, when the cover assembly is in the reset position, the lever 532 and the notch 530 are in the same position as... Figure 8 The state shown; when the cover plate assembly is switching from the reset position to the pressed position, the lever 532 and the notch 530 are in the state shown. Figure 11 The state shown; when the cover assembly has just switched to the pressed position, the lever 532 and the notch 530 are in the state shown. Figure 14 The state shown; when the cover assembly is in the pressed position, the lever 532 and the notch 530 are in the following position. Figure 17 The state shown; when the cover plate assembly is switching from the pressed position to the reset position, the lever 532 and the notch 530 are in the state shown. Figure 20 The state shown; when the cover plate assembly is in the reset position, the lever 532 and the notch 530 are in the following state. Figure 8 The state shown.

[0131] Please continue reading Figure 3 In this embodiment of the invention, the door assembly further includes a light strip and a lampshade covering the light strip. The light strip is detachably mounted on the support, and the lampshade 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 and move synchronously with the cover body.

[0132] By installing light strips on the support, the light strips illuminate the position of the cover assembly when a person approaches the door 500, allowing the user to accurately determine the specific location of the cover assembly. The light strips automatically turn off when the door 500 is closed.

[0133] In this embodiment of the invention, a detection element is installed on the door 500 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 500, 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.

[0134] 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 500 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 position to the pressing position.

[0135] When the door 500 switches from the open state to the closed state, the detection element can detect the movement of the door 500 to generate a detection signal indicating that the door 500 is closed; or, after the user leaves, the detection element can detect that the person has left the vicinity of the door 500 to generate a detection signal indicating that the door 500 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 position to the reset position.

[0136] 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 500, 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.

[0137] 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 position to the pressing position 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 can be manually pressed to make the bracket move to the pressing position. This can effectively avoid the motor being damaged due to large torque.

[0138] 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 hold the bracket in the pressed position according to their actual needs, allowing for convenient door opening at any time. Correspondingly, holding the bracket in the pressed position can be achieved by controlling the motor.

[0139] The clutch mechanism provided in the embodiments of the present invention will be described below:

[0140] like Figure 3 As shown, according to an embodiment of the present invention, the clutch mechanism includes a first clutch bushing 506, a second clutch bushing 508, and an elastic member 516; wherein, the first clutch bushing 506 is mounted on a synchronous shaft 518; the second clutch bushing 508 is mounted on the synchronous shaft 518 via a mounting bushing 509; the elastic member 516 is sleeved on the synchronous shaft 518 and abuts against the side of the second clutch bushing 508 opposite to the first clutch bushing 506 and between the second clutch bushing 508 and the mounting bushing 509; one of the opposing sides of the first clutch bushing 506 and the second clutch bushing 508 is provided with an abutting plane 512 and an inclined acceleration surface 510 connected to each other, and the other is provided with a transition surface 514; when the abutting plane 512 and the transition surface 514 abut against each other, the elastic member 516 is in a compressed state; when the inclined acceleration surface 510 and the abutting plane 512 separate from each other, the elastic member 516 is in a reset process.

[0141] In this embodiment of the invention, a first clutch bushing 506 can be fixedly mounted on the synchronous shaft 518, and a second clutch bushing 508 can be rotatably fitted onto the bushing. It should be noted that the first clutch bushing 506 being fixedly mounted on the synchronous shaft 518 means that the first clutch bushing 506 can rotate synchronously with the synchronous shaft 518, but can slide axially relative to the synchronous shaft 518. An elastic element 516 is provided between the side of the second clutch bushing 508 opposite to the first clutch bushing 506 and the mounting bushing 509. One end of the elastic element 516 is fixed in axial position relative to the synchronous shaft 518, and the other end abuts against the side of the second clutch bushing 508 opposite to the first clutch bushing 506. The elastic element 516 can be a spring, torsion spring, or the like. In this way, under the elastic force of the elastic element 516, the second clutch bushing 508 can always be pressed tightly against the first clutch bushing 506, effectively preventing the support from rotating under its own weight.

[0142] The following describes several different mating methods between the first clutch bushing 506 and the second clutch bushing 508:

[0143] An inclined acceleration surface 510 and an abutment surface 512 are provided on the side of the first clutch bushing 506 facing the second clutch bushing 508.

[0144] Method 1:

[0145] In this engagement configuration, the transition surface 514 provided on the second clutch bushing 508 includes an abutment plane 512.

[0146] See also Figure 7 , Figure 10 , Figure 13 , Figure 16 as well as Figure 19 When the abutting surface 512 on the first clutch bushing 506 and the abutting surface 512 on the second clutch bushing 508 come into contact with each other, the elastic element 516 is in a compressed state. That is, the first clutch bushing 506 and the second clutch bushing 508 can press against each other under the action of the elastic restoring force of the elastic element 516.

[0147] When the drive member 504 drives the second clutch bushing 508 to move, the second clutch bushing 508 rotates relative to the first clutch bushing 506. The abutting surface 512 on the first clutch bushing 506 comes into contact with the abutting surface 512 on the second clutch bushing 508. At this time, the elastic member 516 is in a compressed state. Under these circumstances, the friction between the first clutch bushing 506 and the second clutch bushing 508 increases, and the cover plate assembly will not move under its own weight.

[0148] When the critical point between the contact surface 512 on the first clutch bushing 506 and the contact surface 512 on the second clutch bushing 508 is crossed, the contact relationship between the inclined acceleration surface 510 and the contact surface 512 on the second clutch bushing 508 is released. At this time, the elastic element 516 switches from the compressed state to the original state, and the friction between the second clutch bushing 508 and the first clutch bushing 506 is reduced, thereby enabling the bracket to quickly switch to the pressing position, and thus enabling the cover assembly to quickly switch to the pressing position, making it convenient for the user to open the door 500.

[0149] Understandably, in the above process, the first clutch bushing 506 and the second clutch bushing 508 are first rotated relative to each other by the drive component 504, and then the elastic restoring force of the elastic component 516 accelerates the relative rotation of the first clutch bushing 506 and the second clutch bushing 508, thereby enabling the cover plate assembly to quickly switch to the pressing position or the reset position.

[0150] Method 2:

[0151] In this engagement configuration, the transition surface 514 provided on the second clutch bushing 508 includes an inclined acceleration surface 510 and an abutment surface 512 connected in sequence.

[0152] When the drive member 504 drives the second clutch bushing 508 to move, the second clutch bushing 508 rotates relative to the first clutch bushing 506. The abutting surface 512 on the first clutch bushing 506 comes into contact with the abutting surface 512 on the second clutch bushing 508. At this time, the elastic member 516 is in a compressed state. Under these circumstances, the friction between the first clutch bushing 506 and the second clutch bushing 508 increases, and the cover plate assembly will not move under its own weight.

[0153] When the critical point between the contact surface 512 on the first clutch bushing 506 and the contact surface 512 on the second clutch bushing 508 is crossed, the inclined acceleration surface 510 on the first clutch bushing 506 and the inclined acceleration surface 510 on the second clutch bushing 508 come into contact with each other. At this time, the elastic element 516 switches from the compressed state to the original state, and the friction between the second clutch bushing 508 and the first clutch bushing 506 decreases, thereby enabling the bracket to quickly switch to the pressing position, and thus enabling the cover assembly to quickly switch to the pressing position, making it convenient for the user to open the door 500.

[0154] Method 3:

[0155] In this engagement configuration, the transition surface 514 provided on the second clutch bushing 508 includes an inclined acceleration surface 510.

[0156] When the drive member 504 drives the second clutch bushing 508 to move, the second clutch bushing 508 rotates relative to the first clutch bushing 506. The edge of the inclined acceleration surface 510 on the second clutch bushing 508 comes into contact with the abutment surface 512. At this time, the elastic member 516 is in a compressed state. Under these circumstances, the friction between the first clutch bushing 506 and the second clutch bushing 508 increases, and the cover plate assembly will not move under its own weight.

[0157] When the edge of the inclined acceleration surface 510 on the second clutch bushing 508 and the critical point of the contact plane 512 are crossed, the inclined acceleration surface 510 on the second clutch bushing 508 and the inclined acceleration surface 510 on the first clutch bushing 506 come into contact with each other, the elastic element 516 switches from the compressed state to the original state, the friction between the second clutch bushing 508 and the first clutch bushing 506 decreases, thereby enabling the bracket to quickly switch to the pressing position, thereby enabling the cover assembly to quickly switch to the pressing position, making it convenient for the user to open the door 500.

[0158] When the driving component 504 drives the second clutch bushing 508 to reverse, the second clutch bushing 508 rotates relative to the first clutch bushing 506. When it passes the critical point between the edge of the inclined acceleration surface 510 on the first clutch bushing 506 and the abutment plane 512, the abutment relationship between the inclined acceleration surface 510 on the first clutch bushing 506 and the abutment plane 512 is released, the elastic element 516 switches from the compressed state to the original state, the friction between the second clutch bushing 508 and the first clutch bushing 506 decreases, thereby enabling the bracket to quickly switch to the reset position, and thus enabling the cover plate assembly to quickly switch to the reset position.

[0159] It should be noted that when the synchronous shaft 518 encounters a foreign object and gets stuck during forward or reverse rotation, the transmission connection between the first clutch bushing 506 and the second clutch bushing 508 encounters resistance. At this time, although the spring can still hold the second clutch bushing 508 against the first clutch bushing 506, the resistance is much greater than the elastic support force of the spring, causing the rotational connection between the first clutch bushing 506 and the second clutch bushing 508 to become unstable. That is, the drive shaft no longer moves synchronously with the second clutch bushing 508; the motor only drives the first clutch bushing 506 to idle, and the synchronous shaft 518 no longer rotates.

[0160] When the foreign object is removed, the second clutch bushing 508, under the elastic support force of the elastic element 516, once again engages with the first clutch bushing 506, and at this time the synchronous shaft 518 can continue to transmit power to the motor.

[0161] When a power outage occurs, the motor stops. If the cover assembly is in the reset position, the user can directly press the cover assembly to move it from the reset position to the pressed position. Since the pressure applied by the user to the cover assembly is much greater than the elastic force of the elastic element 516 between the first clutch bushing 506 and the second clutch bushing 508, the user can still hold the exposed handle groove 502 to open the door 500.

[0162] 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 508. When the motor starts to rotate, because of the gap between the motor output shaft and the second clutch bushing 508, the cover plate 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 500 under the action of gravity until the motor engages with the second clutch bushing 508, 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 518 drives the first clutch bushing 506 and the second clutch bushing 508 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 508. 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.

[0163] See also Figure 22 , Figure 24 as well as Figure 26 Because there is a gap between the drive shaft and the transmission sleeve 528, when the drive member 504 drives the bracket, it cannot immediately generate torque on the bracket. Therefore, after the torque applied by the drive member 504 overcomes the frictional torque between the abutment surface 512 on the first clutch sleeve 506 and the transition surface 514 on the second clutch sleeve 508, the first clutch sleeve 506 and the second clutch sleeve 508 can compensate for the gap between the drive shaft and the transmission sleeve 528 through the frictional torque, thereby enabling the drive member 504 to drive the bracket more smoothly. It should be noted that the drive member 504 is connected to the end of the synchronous shaft 518 facing the second clutch sleeve 508. With this configuration, the second clutch sleeve 508 can be driven to move relative to the first clutch sleeve 506.

[0164] 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.

[0165] According to the second aspect of the present invention, the locker provided with the above-mentioned door assembly can improve the speed at which the cover assembly switches between the pressing position and the reset position, and can also improve the movement stability of the cover assembly, making the cover assembly more stable during operation.

[0166] like Figure 27 As shown, a third aspect embodiment of the present invention provides a control method based on the above-described door assembly, comprising:

[0167] Step 100: Determine that the cover plate assembly is in the process of switching from the pressed position to the reset position;

[0168] Step 200: Control the drive device to switch the bracket between the pressing position and the intermediate position;

[0169] Step 300: Control the drive device to switch the bracket from the pressing position or the intermediate position to the reset position;

[0170] The middle position is located between the press position and the reset position.

[0171] According to the control method for a door assembly provided in the third aspect of the present invention, during the process of switching the cover assembly from the pressing position to the reset position, the control bracket switches between the current pressing position and the intermediate position, so that the cover assembly does not move directly to the reset position. This avoids the cover assembly from pinching the user's hand during the reset process, and also avoids overload of the drive device caused by foreign objects being stuck.

[0172] In step 100, the operating state of the cover assembly can be determined by the detection device described above. That is, when the door 500 switches from the open state to the closed state, the detection device can detect the movement of the door 500 to generate a detection signal indicating that the door 500 is closed; or, when the user leaves, the detection device can detect that the person has left the vicinity of the door 500 to generate a detection signal indicating that the door 500 can be closed. At this time, it can be determined that the cover assembly is in the process of switching from the pressed position to the reset position.

[0173] In step 200, the drive device first drives the bracket to switch between a pressing position and an intermediate position. It should be noted that the intermediate position refers to a position between the pressing position and the reset position. This design prevents the cover assembly from immediately returning to the reset position, instead switching between the pressing position and the intermediate position. This prevents injury to the user's hand. Furthermore, if there is a foreign object in the drive device, this design allows the drive device to reciprocate within a small range of swing amplitude, avoiding overload of the drive device.

[0174] In step 300, after the drive device drives the bracket to switch between the pressing position and the intermediate position at least once, it then drives the bracket to switch directly from the pressing position to the reset position, or drives the bracket to switch directly from the intermediate position to the reset position.

[0175] According to one embodiment of the present invention, it further includes:

[0176] Step 400: Determine that the cover plate assembly has switched to the reset position and the drive device has been stalled for a preset time.

[0177] After step 300, in order to ensure that the cover plate assembly can be accurately switched to the reset position, the drive device can be stalled for a preset time after the cover plate assembly is switched to the reset position. By setting it in this way, it can be ensured that both ends of the bracket can be accurately switched to the reset position.

[0178] like Figure 28 As shown, a fourth aspect embodiment of the present invention provides a control device for a door assembly, comprising:

[0179] The determination module 538 is used to determine that the cover plate assembly is in the process of switching from the pressed position to the reset position;

[0180] The first control module 540 is used to control the drive device to switch the bracket between the pressing position and the intermediate position.

[0181] The second control module 542 is used to control the drive device to switch the bracket from the pressing position or the intermediate position to the reset position.

[0182] The middle position is located between the press position and the reset position.

[0183] Figure 29 An example is a schematic diagram of the physical structure of an electronic device, such as... Figure 29 As shown, the electronic device may include a processor 544, a communication interface 546, a memory 548, and a communication bus 550.

[0186] The control drive device moves the bracket from the pressing position or intermediate position to the reset position;

[0187] The middle position is located between the press position and the reset position.
