As shown inFIG.1toFIG.25, a door assembly according to an embodiment of the present application mainly includes a door body100, a driving assembly, a rack and a first detecting member (not shown in the figures). The door body100is provided with a handle groove102; the rack is hinged to the door body100and provided with a cover plate assembly; the first detecting member is configured to generate a first detecting signal; the driving assembly is adapted to drive the rack to switch between a pressing state and a resetting state based on the first detecting signal; and in the pressing state, the cover plate assembly avoids the handle groove102, and in the resetting state, the cover plate assembly shields the handle groove102.

According to the door assembly provided by the embodiment of the present application, when a door needs to be opened, the first detecting member can generate a first detecting signal indicating an opening of the door, the driving assembly can drive the rack to switch from the resetting state to the pressing state based on the first detecting signal, and then the handle groove102can be exposed on the door body100. At this time, the door body100can be opened by bucking and pulling the handle groove102. In this way, the door body100can be opened without providing a handle on the door body100or providing a handle plate on a surface of the door body100, so as to ensure the flatness of a front of the door body100. When an action of closing the door body100occurs or the door body100is already in a closed state, the first detecting member can generate a first detecting signal indicating an closing of the door, and the driving assembly can drive the cover plate assembly to return to the resetting state and shield the handle groove102based on the first detecting signal, and then the door body100can recover to a flat and concise state, which not only ensures the flatness and conciseness of the door body100, but also is convenient for a user to open and close the door body100.

The door assembly provided by the embodiments of the present application applying to a refrigerator will be taken as an example in the following. In the embodiments of the present application, the number of the door body100can be one or more. In other words, the door assembly provided by the embodiments of the present application can be applied to a single door refrigerator or an opposite door refrigerator.

The door body100is provided with a handle groove102that can be buckled by a user. When the handle groove102is exposed outside, the user can hold the handle groove102to open the door body100.

It should be noted that, referring toFIG.1toFIG.4andFIG.6, the position of the door assembly provided by the embodiments of the present application on the door body100is not limited.

As shown inFIG.1andFIG.6, when the number of the door body100is one, the handle groove102can be provided near an edge of the door body100, for example, the handle groove102can be provided at the area shown by the dotted line inFIG.1. After the driving assembly drives the cover plate assembly to switch to the pressing state, the handle groove102provided on the door body100can be exposed.

As shown inFIG.2toFIG.4andFIG.6, when the number of the door bodies100is multiple, the handle groove102can be provided at an edge of any door body100, and it can also be provided at a non-edge position of the door body100as required. Therefore, when the user intends to open the door body100, the driving assembly can drive the cover plate assembly on the door body100, and then the handle groove102on the door body100can be exposed, so that the user can hold the handle groove102to open the door body100.

Alternatively, the driving assembly is configured to drive the cover plate assembly on the door body100to expose the handle groove102on the adjacent door body100, and then the user can open the adjacent door body100. In other words, the user can flexibly choose to open the corresponding door body100according to an actual demand.

The areas shown by the dotted line inFIG.2toFIG.4are the areas of providing the handle groove102, for example, when the number of door bodies100is multiple, multiple handle grooves102can be provided on two adjacent door bodies100respectively, which can facilitate the user to open the door bodies100.

In an embodiment of the present application, the door assembly further includes a supporting base104mounting on the door body100, and the above-mentioned handle groove102is provided on the supporting base104. For example, the supporting base104can be mounted in a foaming layer of the door body100.

According to an embodiment of the present application, the door assembly further includes a mounting base146, where the mounting base146is provided on the door body100, and the supporting base104is mounted on the mounting base146. The shape of the mounting base146is adapted to the shape of the supporting base104. The mounting base146can be provided in the foaming layer of the door body100. By providing the mounting base146in the foaming layer of the door body100, the foaming material in the foaming layer can be prevented from entering the supporting base104, thereby preventing the foaming material from affecting the components such as the supporting base104, the rack and the cover plate assembly.

A first end of the rack is hinged to the supporting base104, a second end of the rack is provided with a cover plate assembly, and the rack is adapted to switch between the pressing state and the resetting state. In the pressing state, the cover plate assembly avoids the handle groove102; and in the resetting state, the cover plate assembly shields the handle groove102.

As mentioned above, when the rack is in the pressing state, the cover plate assembly mounted on the rack can avoid the handle groove102, so that the handle groove102is exposed outside, and then the user can hold the handle groove102to open the door body100. When the rack is in the resetting state, the cover plate assembly mounted on the rack can shield the handle groove102, so that the door body100is in a flat and concise state. The pressing state mentioned here refers to that when the driving assembly drives the rack to move the cover plate assembly toward the position retracted to the door body100, the cover plate assembly exposes the handle groove102to the outside, and at this time, the rack is in the pressing state. The resetting state refers to that the rack is driven to switch the cover plate assembly from the state of being retracted to the door body100to the state of being flush with an outer surface of the door body100, and at this time, the rack is in the resetting state.

In an embodiment of the present application, the driving assembly can be mounted in the supporting base104, where the driving assembly is mainly configured to control the rack to switch between the pressing state and the resetting state.

According to an embodiment of the present application, the rack includes a first swiveling rack106and a second swiveling rack108. A first end of the first swiveling rack106is hinged to the supporting base104, and a second end of the first swiveling rack106is hinged to the cover plate assembly. A first end of the second swiveling rack108is hinged to the supporting base104, and a second end of the swiveling rack108is hinged to the cover plate assembly. The driving assembly is adapted to drive the first swiveling rack106and/or the second swiveling rack108, to move the cover plate assembly in a direction perpendicular to the door body100.

Referring toFIG.10, for example, the first swiveling rack106and the second swiveling rack108together constitute the rack in the embodiments of the present application. The first end of the first swiveling rack106and the first end of the second swiveling rack108are respectively hinged to the supporting base104, and the second end of the first swiveling rack106and the second end of the second swiveling rack108are respectively hinged to the cover plate assembly. In this way, the cover plate assembly can move relative to the supporting base104under the hinged action of the first swiveling rack106and the second swiveling rack108.

In an embodiment, the driving assembly can be connected to the first swiveling rack106or the second swiveling rack108respectively, or the driving assembly can be connected to the first swiveling rack106and the second swiveling rack108respectively. Through the driving of the driving assembly, the first swiveling rack106and/or the second swiveling rack108can be led to swivel, so as to move the cover plate assembly relative to the supporting base104. In an embodiment of the present application, the first swiveling rack106and the second swiveling rack108can be drive to move the cover plate assembly in a direction perpendicular to the door body100. For example, the cover plate assembly can move in a direction perpendicular to the door body100relative to the door body100.

According to an embodiment of the present application, the first swiveling rack106includes a first driving shaft110, a first driven shaft112and a first transition connecting member114. The second swiveling rack108includes a second driving shaft116, a second driven shaft118and a second transition connecting member120. Two ends of the first driving shaft110are hinged to the supporting base104, two ends of the first driven shaft112are hinged to the cover plate assembly, and the first transition connecting member114is connected between the first driving shaft110and the first driven shaft112. Two ends of the second driving shaft116are hinged to the supporting base104, two ends of the second driven shaft118are hinged to the cover plate assembly, and the second transition connecting member120is connected between the second driving shaft116and the second driven shaft118.

For example, referring toFIG.9toFIG.12, two ends of the first driving shaft110and two ends of the second driving shaft116are hinged to the supporting base104respectively, and the two ends of the first driven shaft112and the two ends of the second driven shaft118are hinged to the cover plate assembly respectively. In order to improve the connection stability between the first driving shaft110and the first driven shaft112, the first transition connecting member114is connected between the first driving shaft110and the first driven shaft112. Correspondingly, a second transition connecting member120is connected between the second driving shaft116and the second driven shaft118.

It should be noted that when the driving assembly is only connected to the first driving shaft110of the first swiveling rack106, the first driven shaft112, the second driving shaft116and the second driven shaft118can be set to be disconnected in the middle, and it is only needed to set a length of the first driving shaft110to be equal to a width of the supporting base104.

Referring toFIG.14,FIG.16andFIG.18, these figures show a hinge point of the first driving shaft110and the supporting base104, a hinge point of the second driving shaft116and the supporting base104, a hinge point of the first driven shaft112and the cover plate assembly, and a hinge point of the second driven shaft118and the cover plate assembly. A parallelogram can be formed by connecting these four hinge points in sequence. Since the hinge point of the first driving shaft110and the supporting base104and the hinge point of the second driving shaft116and the supporting base104are fixed points, a relative distance between the two hinge points and an inclination angle of the connecting line of the two hinge points is also fixed. Therefore, a distance between the hinge point of the first driven shaft112and the cover plate assembly and the hinge point of the second driven shaft118and the cover plate assembly is equal to the distance between the hinge point of the first driving shaft110and the supporting base104and the hinge point of the second driving shaft116and the supporting base104. The connecting line between the hinge point of the first driven shaft112and the cover plate assembly and the hinge point of the second driven shaft118and the cover plate assembly is parallel to the connecting line between the hinge point of the first driving shaft110and the supporting base104and the hinge point of the second driving shaft116and the supporting base104, and then as shown inFIG.14,FIG.16orFIG.18, the cover plate assembly can perform vertical translational motion along the direction perpendicular to the door body100.

In an embodiment, as shown inFIG.18, during the cover plate assembly moving from the position of shielding the handle groove102to the position of avoiding the handle groove102, the cover plate assembly first translates to a left side as shown inFIG.18for a distance about 1 mm to 3 mm, and then translates to a right side as shown inFIG.18for a distance about 1 mm to 3 mm, and finally moves to the position of avoiding the handle groove102as shown inFIG.16. Similarly, during the cover plate assembly moving from the position of avoiding the handle groove102to the position of shielding the handle groove102, the cover plate assembly first translates to the left side as shown inFIG.18for a distance about 1 mm to 3 mm, and then translates to the right side as shown inFIG.18for a distance about 1 mm to 3 mm, and finally moves to the position of shielding the handle groove102as shown inFIG.14.

According to an embodiment of the present application, the first transition connecting member114is adapted to be positioned at the first driving shaft110and/or the first driven shaft112through a first limiting structure122; and the second transition connecting member120is adapted to be positioned at the second driving shaft116and/or the second driven shaft118through a second limiting structure124.

In an embodiment of the present application, in order to prevent the first transition connecting member114from performing axial movement relative to the first driving shaft110and/or the first driven shaft112, the first driving shaft110and the first driven shaft112can be provided with two first positioning blocks respectively, and a first end of the first transition connecting member114can be connected between the two first positioning blocks on the first driving shaft110, and a second end of the first transition connecting member114can be connected between the two first positioning blocks on the first driven shaft112. In other embodiments, two first positioning blocks may be only provided on the first driving shaft110or the first driven shaft112, and then the first transition connecting member114may be connected between the two first positioning blocks. In this way, the objective of preventing the first transition connecting member114from performing axial movement relative to the first driving shaft110or the first driven shaft112can also be achieved.

Similarly, the second driving shaft116and the second driven shaft118can be provided with two second positioning blocks respectively. A first end of the second transition connecting member120can be connected between the two second positioning blocks on the second driving shaft116, and a second end of the second transition connecting member120can be connected between the two second positioning blocks on the second driven shaft118. In other embodiments, two second positioning blocks may be only provided on the second driving shaft116or the second driven shaft118, and then the second transition connecting member120may be connected between the two second positioning blocks. In this way, the objective of preventing the second transition connecting member120from performing axial movement relative to the second driving shaft116or the second driven shaft118can also be achieved.

In other embodiments, the positions of the first transition connecting member114and the second transition connecting member120can be limited in other forms. For example, the first driving shaft110and/or the second driving shaft116are provided with positioning pins, positioning bosses, etc.

Referring toFIG.14,FIG.16andFIG.18, for the consideration of space layout, both of the first transition connecting member114and the second transition connecting member120can have a shape of bending toward an inner surface of the door body100. Correspondingly, the supporting base104is provided with an accommodation space for accommodating a bent portion of the first transition connecting member114and a bent portion of the second transition connecting member120. In an embodiment, as long as the first transition connecting member114can be connected to the first driving shaft110and the second driving shaft116, a width of the first transition connecting member114does not need to be set to equal with the length of the first driving shaft110, and as long as the second transition connecting member120can be connected to the second driving shaft116and the second driven shaft118, a width of the second transition connecting member120does not need to be set to equal with the length of the second driving shaft116. In addition, in some embodiments of the present application, the positions of the first transition connecting member114and the second transition connecting member120are staggered in a spatial width direction, to avoid an interference between the first transition connecting member114and the second transition connecting member120during rotation.

In order to prevent the first transition connecting member114and/or the second transition connecting member120from disengaging from the supporting base104, the first transition connecting member114and/or the second transition connecting member120is adapted to be limited at the supporting base104through a groove side wall of the handle groove102.

Referring toFIG.14, the handle groove102is a groove-like structure formed on an edge of the supporting base104. Therefore, as shown inFIG.10, the groove side wall located below of the handle groove102can be used as a limiting structure for preventing the first transition connecting member114and the second transition connecting member120from disengaging from the supporting base104. In other words, as shown inFIG.14, when the rack is switched to the resetting state, a side of the first transition connecting member114facing an outer side surface of the door body100and a side of the second transition connecting member120facing the outer side surface of the door body100can abut against on the groove side wall located below of the handle groove102, so that the first transition connecting member114and the second transition connecting member120can be prevented from disengaging from the supporting base104, and correspondingly, the first swiveling rack106and the second swiveling rack108are prevented from disengaging from the supporting base104. It should be noted that the term “disengaging” here means that the connection position of the first transition connecting member114and the first driven shaft112and/or the connection position of the second transition connecting member120and the second driven shaft118protrudes from the outer surface of the door body100.

According to an embodiment of the present application, the cover plate assembly includes a cover plate base140and a cover plate body142. Two ends of the first driven shaft112and two ends of the second driven shaft118are hinged to the cover plate base140respectively. The cover plate body142is mounted on the cover plate base140.

Referring toFIG.9toFIG.12, two ends of the first driven shaft112and two ends of the second driven shaft118are hinged to the cover plate base140respectively, and a cover plate body142is mounted on the cover plate base140. The cover plate body142can be fixed with the cover plate base140by means of bonding, clamping, or the like. In other words, when the driving assembly drives the first swiveling rack106and/or the second swiveling rack108to operate, the first swiveling rack106and/or the second swiveling rack108can be driven to switch the cover plate base140and the cover plate body142between the position of avoiding the handle groove102and the position of shielding the handle groove102. In an embodiment, the cover plate body142can be made of the same material as the outer surface of the door body100, which can further improve the appearance consistency of the outer surface of the door body100.

In an embodiment of the present application, as shown inFIG.10, the door assembly further includes a light bar144. In an embodiment, the cover plate base140is provided with a mounting space for mounting the light bar144, and the cover plate body142is provided with a light transmission area at a position corresponding to the light bar144. In other embodiments, the light bar144can be directly mounted under the cover plate body142and can act synchronously with the cover plate body142.

By providing the mounting space for mounting the light bar144on the cover plate base140and providing a corresponding light transmission area on the cover plate body142, when a human body approaches the door body100, the first detecting member can detect the human body and generate a corresponding control signal. The light bar144can be automatically lit up after receiving the control signal, so that the user can recognize the position of the cover plate body142. When the door body100is closed, the light bar144can be automatically turned off.

In an embodiment of the present application, the first detecting member is configured to detect the opening and closing states of the door body100or whether the user has leaved in addition to detect whether the human body is approaching. When the above situation is detected by the first detecting member, the first detecting member can generate a first detecting signal for controlling the driving assembly.

In an embodiment, when the first detecting member detects that a human body is approaching, which generally means that the user has a need to open the door, and the first detecting member is configured to generate the first detecting signal indicating that the door will be opened. After receiving the first detecting signal, the driving assembly can drive the first swiveling rack106and/or the second swiveling rack108to switch from the resetting state to the pressing state.

When the door body100is switched from the opening state to the closing state, the first detecting member can detect the action of the door body100to generate a first detecting signal indicating that the door body100is closed; or, when the user has left, the first detecting member can detect that the human body has left a nearby area of the door body100and generate a first detecting signal indicating that the door body100can be closed. After receiving the first detecting signal, the driving assembly can drive the first swiveling rack106and/or the second swiveling rack108to switch from the pressing state to the resetting state.

It should be noted that, in addition to sensors (such as infrared sensors and laser sensors) for detecting the distance of the human body, a sensor for detecting human biometric features (such as face recognition devices, voice recognition devices, etc.) can be selected as the first detecting member, and a pressure sensor and other sensors can also be selected as the first detecting member. For example, when the user touches a certain area of the door body, the first detecting signal is generated. That is, the present application does not have specific limitation on types and excitation methods of the first detecting member, as long as the opening and closing needs of the user can be determined.

Several ways of providing the driving assembly according to the embodiments of the present application will be described in the following.

Way I

The driving assembly includes a motor126mounted on the supporting base104, and the motor126is connected to the first driving shaft110and/or the second driving shaft116.

For example, in the way I, the motor126can be connected to the first driving shaft110, so that when the door body100is in a closed state, if the first detecting member detects that a human body is approaching, which generally means that the user has a need to open the door, the first detecting member is configured to generate the first detecting signal indicating that the door will be opened. The motor126drives the first driving shaft110to move, so that the first swiveling rack106is switched from the resetting state to the pressing state, then the user can hold the handle groove102to open the door body100. After the user leaves or the user closes the door body100, the first detecting member can generate the first detecting signal indicating that the door body100is closed, and the motor126drives the first driving shaft110to swivel based on the first detecting signal, thereby switching the first swiveling rack106from the pressing state to the resetting state. Meanwhile, the second swiveling rack108is simultaneously switched from the pressing state to the resetting state under the leading of the first swiveling rack106.

In an embodiment, the motor126can be connected to the second driving shaft116, so that the second driving shaft116can be driven by the motor126, so that the second swiveling rack108can be switched from the pressing state to the resetting state.

In an embodiment, the number of the motors126can be two. For example, the two motors126are connected to the first driving shaft110and the second driving shaft116respectively. One of the two motors126is configured to drive the first driving shaft110, so that the first swiveling rack106can be switched from the pressing state to the resetting state; and another motor126is configured to drive the second driving shaft116, so that the second swiveling rack108can be switched from the resetting state to the pressing state.

Way II

The driving assembly includes a motor126and an elastic member128; the motor126is connected to the first driving shaft110and/or the second driving shaft116; and the elastic member128is sleeved on the first driving shaft110and two ends of the elastic member128abut against the supporting base104and the first transition connecting member114respectively, and/or the elastic member128is sleeved on the second driving shaft116and two ends of the elastic member128abut against the supporting base104and the second transition connecting member120respectively.

In way II, referring toFIG.19toFIG.24, the motor126being connected to the first driving shaft110and the elastic member128being sleeved on the first driving shaft110are taken as an example.

The motor126is connected to the first driving shaft110in a transmission manner and the elastic member128can be a torsion spring. The torsion spring is sleeved on the first driving shaft110, and two ends of the torsion spring abut against the supporting base104and a side of the first transition connecting member114facing the inner surface of the door body100respectively.

In this way, when the door body100is in a closed state and the user approaches the door body100, the first detecting member can control the motor126to operate, and then the motor126can be driven to swivel the first driving shaft110, so that the rack is switched from the resetting state to the pressing state, and then the user can hold the handle groove102to open the door body100, and at this time the torsion spring is tightened. After the user leaves or the user closes the door body100, the torsion spring drives the first driving shaft110to swivel reversely under the action of torsional restoring force of the torsion spring, thereby switching the first swiveling rack106from the pressing state to the resetting state, and then the second swiveling rack108is synchronously switched from the pressing state to the resetting state under the leading of the first swiveling rack106.

Alternatively, the motor126is connected to the first driving shaft110, the torsion spring is sleeved on the first driving shaft110, and two ends of the torsion spring abut against the supporting base104and a side of the first transition connecting member114facing the outer surface of the door body100respectively.

In this way, when the door body100is in the closed state, the torsion spring is in a tightened state, the motor126stops operating and is balanced with the torsional restoring force of the torsion spring. When the user approaches the door body100, the first detecting member can control the motor126to operate to loosen the torsion spring, and then the torsion spring swivels the first driving shaft110under the action of its own torsional restoring force, so that the first swiveling rack106can be switched from the resetting state to the pressing state, and then the user can hold the handle groove102to open the door body100. After the user leaves or the user closes the door body100, the motor126operates reversely and swivels the first driving shaft110to overcome the torsional restoring force exerted by the torsion spring on the first transition connecting member114, thereby switching the first swiveling rack106from the pressing state to the resetting state, and then the second swiveling rack108is simultaneously switched from the pressing state to the resetting state under the leading of the first swiveling rack106. It should be noted that, during the rack switches from the resetting state to the pressing state, a smooth movement of the cover plate body142can be achieved by controlling a operation speed of the first swiveling rack106by controlling a rotational speed of the motor126. Similarly, during the rack switches from the pressing state to the resetting state, the smooth movement of the cover plate body142can also be achieved by controlling the rotational speed of the motor126.

In other words, in way II, the motor126can drive the rack to switch from the resetting state to the pressing state, and the torsion spring can drive the rack to switch from the pressing state to the resetting state; or the motor126drives the rack to switch from the pressing state to the resetting state, and the torsion spring drives the rack to switch from the resetting state to the pressing state.

In an embodiment, in way II, the motor126can be connected to the first driving shaft110, the torsion spring is sleeved on the second driving shaft116, and two ends of the torsion spring abut against the supporting base104and a side of the second transition connecting member120facing the inner surface of the door body100respectively. In this way, the first swiveling rack106can be driven by the motor126to switch from the resetting state to the pressing state, and the second swiveling rack108can be driven by the torsion spring to switch from the pressing state to the resetting state.

Alternatively, the motor126is connected to the first driving shaft110, the torsion spring is sleeved on the second driving shaft116, and two ends of the torsion spring abut against the supporting base104and a side of the second transition connecting member120facing the outer surface of the door body100respectively. In this way, the first swiveling rack106can be driven by the motor126to switch from the pressing state to the resetting state, and the second swiveling rack108can be driven by the torsion spring to switch from the resetting state to the pressing state.

Alternatively, the motor126is connected to the second driving shaft116, the torsion spring is sleeved on the first driving shaft110, and two ends of the torsion spring abut against the supporting base104and a side of the first transition connecting member114facing the inner surface of the door body100respectively. In this way, the second swiveling rack108can be driven by the motor126to switch from the resetting state to the pressing state, and the first swiveling rack106can be driven by the torsion spring to switch from the pressing state to the resetting state.

Alternatively, the motor126is connected to the second driving shaft116, the torsion spring is sleeved on the first driving shaft110, and two ends of the torsion spring abut against the supporting base104and a side of the first transition connecting member114facing the outer surface of the door body100respectively. In this way, the first swiveling rack106can be driven by the motor126to switch from the resetting state to the pressing state, and the second swiveling rack108can be driven by the torsion spring to switch from the resetting state to the pressing state.

Alternatively, the motor126is connected to the second driving shaft116, the torsion spring is sleeved on the second driving shaft116, and two ends of the torsion spring abut against the supporting base104and a side of the second transition connecting member120facing the inner surface of the door body100respectively. In this way, the second swiveling rack108can be driven by the motor126to switch from the resetting state to the pressing state, and the second swiveling rack108can be driven by the torsion spring to switch from the pressing state to the resetting state.

Alternatively, the motor126is connected to the second driving shaft116, the torsion spring is sleeved on the second driving shaft116, and two ends of the torsion spring abut against the supporting base104and a side of the second transition connecting member120facing the outer surface of the door body100respectively. In this way, the second swiveling rack108can be driven by the motor126to switch from the pressing state to the resetting state, and the second swiveling rack108can be driven by the torsion spring to switch from the resetting state to the pressing state.

Alternatively, the motor126is connected to the first driving shaft110and the second driving shaft116, and both the first driving shaft110and the second driving shaft116are provided with a torsion spring. The motor126is configured to simultaneously drive the first driving shaft110and the second driving shaft116to switch from the resetting state to the pressing state. Correspondingly, the torsion springs simultaneously drive the first driving shaft110and the second driving shaft116to switch from the pressing state to the resetting state. Alternatively, the motor126is configured to simultaneously drive the first driving shaft110and the second driving shaft116to switch from the pressing state to the resetting state, and correspondingly, the torsion springs simultaneously drive the first driving shaft110and the second driving shaft116to switch from the resetting state to the pressing state.

It should be noted that, when the power is off, if the rack is in the resetting state, the user can manually press the cover plate assembly to switch the cover plate assembly from the resetting state to the pressing state, thereby the use can hold the handle groove102to open the door.

Way III

The driving assembly includes a magnetic member, where the magnetic member is mounted on the supporting base104, and the magnetic member is adapted to drive the rack to switch between the pressing state and the resetting state based on the first detecting signal.

In way III, the magnetic member can be an electromagnet, and the number of the electromagnets can be two, where one of the two electromagnets is configured to drive the rack to switch from the resetting state to the pressing state, and another electromagnet is configured to drive the rack to switch from the pressing state to the resetting state.

In this way, when the door body100is in the closed state, after one of the two electromagnets receives the first detecting signal indicating that the door will be opened, the electromagnet is powered up and generates a magnetic force on the first swiveling rack106and/or the second swiveling rack108, thereby driving the rack to switch from the resetting state to the pressing state, and then the user can hold the handle groove102to open the door body100. After the user leaves or the user closes the door100, this electromagnet is powered off, and another electromagnet is powered up and generates a magnetic force on the first swiveling rack106and/or the second swiveling rack108, to switch the first swiveling rack106and/or the second swiveling rack108from the pressing state to the resetting state.

Way IV

The driving assembly includes a magnetic member and an elastic member128, where the magnetic member is mounted on the supporting base104, the elastic member is adapted to drive the rack to switch from the resetting state to the pressing state, and the magnetic member is adapted to drive the rack to switch from the pressing state to the resetting state.

Alternatively, the magnetic member is adapted to drive the rack to switch from the resetting state to the pressing state, and the elastic member is adapted to drive the rack to switch from the pressing state to the resetting state.

For the above-mentioned way I and way II, the supporting base104is further provided with a mounting plate134for mounting the motor126, where the mounting plate134is provided with a shock pad136, the motor126is mounted on the mounting plate134and an output shaft of the motor126is adapted to be connected to an end of the first driving shaft110and/or an end of the second driving shaft116through a shaft coupling138.

Alternatively, as shown inFIG.25, the motor126can drive the first driving shaft110through the meshing transmission of a driving gear152and a driven gear154. In other words, in this way, the motor126can be mounted at a middle position of the first driving shaft110, which can save the mounting space of the motor126and reduce the space occupation of the driving assembly.

Referring toFIG.10, by providing the shock pad136, the vibration of the motor126during operation can be reduced, and the movement stability of the first swiveling rack106and/or the second swiveling rack108during swiveling can be improved. A shaft coupling138is provided between the output shaft of the motor126and the first driving shaft110and/or the second driving shaft116. For example, the output shaft of the motor126, the first driving shaft110and the second driving shaft116can be flat shafts, and correspondingly, a shaft hole on the shaft coupling138can be flat hole. In this way, the objective of swiveling the first driving shaft110and/or the second driving shaft116by the motor126can be achieved.

According to an embodiment of the present application, the door assembly further includes a second detecting member130, where the second detecting member130is mounted on the supporting base104, and the second detecting member130is adapted to generate a second detecting signal for controlling the motor126to stop after detecting that the rack switches to the resetting state.

For the above-mentioned way I and way II, the supporting base104is further provided with a second detecting member130. The second detecting member130can be a micro switch or a proximity switch, etc. By providing the second detecting member130, after the rack switches from the pressing state to the resetting state, the second detecting member130can detect the position of the rack and generate a second detecting signal. In the above-mentioned way I and way III, when the motor126is configured to drive the rack to switch from the pressing state to the resetting state, the motor126can be stopped based on the second detecting signal.

In other words, after the motor126drives the rack to switch from the pressing state to the resetting state, the second detecting member130is triggered and generates a second detecting signal, and then the motor126can be stopped after receiving the second detecting signal, so that the rack can stay in the resetting state.

Referring toFIG.6andFIG.7, the first driving shaft110and/or the second driving shaft116is sleeved with a swing rod132. In the resetting state, the swing rod132is adapted to trigger the second detecting member130to generate the second detecting signal.

In an embodiment, the swing rod132is connected to the first driving shaft110, and the swing rod132is provided with a swing arm150. For example, the swing rod132is provided with a flat hole, and the swing rod132is sleeved on the first driving shaft110through the flat hole. The swing arm150includes a first swing arm and a second swing arm. After the motor126drives the first driving shaft110to swivel and switches the first swiveling rack106from the pressing state to the resetting state, the first swing arm on the swing rod132can trigger the second detecting member130to generate the second detecting signal, then the motor126stops after receiving the second detecting signal, and then the rack can be kept in the resetting state.

As shown inFIG.10toFIG.12, in an embodiment of the present application, the door assembly is further provided with a third detecting member148. The third detecting member148can be mounted on the supporting base104, and the third detecting member148can be a micro switch or a proximity switch, etc. By providing the third detecting member148, after the rack switches from the resetting state to the pressing state, the third detecting member148can detect the position of the rack and generate a third detecting signal. In the above-mentioned way I and way III, when the motor126is configured to drive the rack to switch from the resetting state to the pressing state, the motor126can be stopped based on the third detecting signal.

Similarly, in the pressing state, the swing rod132is adapted to trigger the third detecting member148to generate a third detecting signal. In an embodiment, the swing rod132is connected to the first driving shaft110. For example, the swing rod132is provided with a flat hole, and the swing rod132is sleeved on the first driving shaft110through the flat hole. After the motor126swivels the first driving shaft110and drives the first swiveling rack106to switch from the resetting state to the pressing state, the second swing arm on the swing rod132can trigger the third detecting member148to generate a third detecting signal, then the motor126stops after receiving the third detecting signal, and then the rack can be kept in the pressing state.

It should be noted that, in the case where the third detecting member148is provided, the first swing arm and the second swing arm on the swing rod132are provided at a certain angle. That is, with the swivel of the first driving shaft110, the first swing arm and the second swing arm on the swing rod132can trigger the second detecting member130and the third detecting member148respectively to control the motor126to stop.

In an embodiment of the present application, the second detecting member130and the third detecting member148may not be provided, and the controlling mode of the motor126for the first swiveling rack106and/or the second swiveling rack108can be adjusted only by setting the running duration of the motor126.

For example, the motor126can be set to automatically stop after a running duration of 2 seconds. For example, when the motor126is stuck by foreign object when the motor126drives the first swiveling rack106to switch from the resetting state to the pressing state, the motor126stops after running 2 seconds. After the foreign object is taken out, the cover plate body142can be manually pressed to switch the rack to the pressing state, which can effectively prevent the motor126from being damaged due to a larger torque on the motor126. The above-mentioned 2 seconds is only an illustrative example, and the running duration of the motor126can be selected within the range of 1 to 5 seconds.

By setting the running duration of the motor126as a preset duration, the motor126can automatically stop after the running duration reaches the preset duration, so that the second detecting member130and the third detecting member148are not needed to be provided, which will further reduce the costs of design and manufacturing. In addition, the rack can be kept in the pressing state according to user's actual usage needs, so as to facilitate the user to open the door body100at any time. Correspondingly, the objective of keeping the rack in the pressing state can be achieved by controlling the motor126.

A storage cabinet according to an embodiment of the present application includes the above-mentioned door assembly.

According to the storage cabinet of the embodiment of the present application, by providing the above-mentioned door assembly, on the premise of ensuring the convenience of opening and closing the door body100, the surface of the door body100can be kept flat and concise when the door body100is in the closed state.

In an embodiment of the present application, the storage cabinet can be a refrigerator, a freezer, a wine cabinet, or the like.
