As shown in fig. 1 to 20, the door assembly according to the embodiment of the first aspect of the present invention mainly includes a door body 100, a cover plate 104, a bracket, and a reset member 106. A handle groove 102 is formed on the door body 100; two ends of the bracket are respectively hinged to the door body 100 and the cover plate 104, and the bracket is suitable for switching between a pressing state and a resetting state; in the pressed state, the cover plate 104 avoids the handle groove 102, and in the reset state, the cover plate 104 shields the handle groove 102; the reset member 106 is used for driving the stand to switch from the pressing state to the resetting state.

According to the door assembly of the first aspect of the present invention, when the door needs to be opened, the handle groove 102 can be exposed on the door body 100 by pressing the cover plate 104, and at this time, the handle groove 102 can be buckled to open the door body 100, so that there is no need to provide a handle on the door body 100, and there is no need to provide a handle plate on the surface of the door body 100, thereby ensuring that the front surface of the door body 100 is flat. After the door body 100 is opened, the reset piece 106 can drive the bracket to restore to the reset state and enable the cover plate 104 to cover the handle slot 102, so that the door body 100 can restore to a flat and simple state, and the door body 100 can be conveniently opened and closed by a user while the door body 100 is ensured to be flat and simple. Two ends of the bracket are respectively hinged to the door body 100 and the cover plate 104, so that the cover plate 104 can be ensured to translate, the structure of the door body 100 is simplified, and the reliability of the cover plate 104 during movement is improved.

In the following, taking the example of applying the door assembly provided in the first aspect of the present invention to a refrigerator as an example, in the embodiment of the present invention, there may be one or more door bodies 100, in other words, the door assembly provided in the embodiment of the present invention may be applied to refrigerators with various door body forms.

A handle slot 102 is formed in the door body 100 for a user to catch, and when the handle slot 102 is exposed, the user can catch the handle slot 102 to open the door body 100.

It should be noted that, referring to fig. 1 to 4 and fig. 6 in combination, the position of the door assembly on the door body 100 provided in the embodiment of the present invention is not limited, and in some specific embodiments.

As shown in fig. 1 and 6, when the door body 100 is a single body, the handle groove 102 may be formed near an edge of the door body 100, that is, a region shown by a dotted line in fig. 1, that is, a region of the handle groove 102, and when a user presses the cover plate 104, the handle groove 102 provided on the door body 100 may be exposed.

As shown in fig. 2 to 4 and 6, when there are a plurality of door bodies 100, the handle groove 102 may be formed at a side edge position of any one of the door bodies 100, or may be formed at a non-edge position of the door body 100 as needed. Therefore, when a user needs to open the front door body 100, the user can press the cover plate 104 on the door body 100, and then the user can fasten the handle slot 102 on the door body 100 to open the door body 100. Or the user can also press the cover plate 104 on the door body 100 to expose the handle slot 102 on the door body 100 adjacent to the cover plate, so that the user can open the door body 100 adjacent to the cover plate, in other words, the user can flexibly select to open the corresponding door body 100 according to the actual door opening requirement. The area shown by the dotted line in fig. 2 to fig. 4 is the area of the handle groove 102, that is, when there are a plurality of door bodies 100, the handle groove 102 may be disposed on two adjacent door bodies 100, so that a user can open the required door bodies 100 conveniently. In the embodiment of the present invention, the door body 100 further includes the seat 124, for example, the seat 124 may be installed in a foamed layer of the door body 100, and the above-mentioned handle groove 102 is formed on the seat 124.

According to an embodiment of the present invention, the door body 100 further includes a mounting seat 132, and the support 124 is mounted to the mounting seat 132. Thus, the shape of the mounting seat 132 conforms to the shape of the support 124. The mounting seat 132 may be disposed in a foamed layer of the door body 100, and by disposing the mounting seat 132 in the foamed layer of the door body 100, a foamed material in the foamed layer can be prevented from entering the support 124, thereby avoiding an influence of the foamed material on the support 124, the bracket, the cover plate 104, and other components.

A first end of the bracket is hinged to the support 124, a second end of the bracket is hinged to the cover plate 104, and the bracket is suitable for switching between a pressing state and a resetting state; in the pressed state, the cover plate 104 is retracted from the handle groove 102, and in the reset state, the cover plate 104 shields the handle groove 102.

As described above, when the bracket is in the pressed state, the cover plate 104 mounted on the bracket can be moved away from the handle groove 102, so that the handle groove 102 is exposed, and at this time, the user can buckle the handle groove 102 to open the door 100. When the bracket is in the reset state, the cover plate 104 mounted on the bracket can shield the handle slot 102, so that the door body 100 is in a flat and concise state. The pressing state mentioned here means that after the user presses the cover plate 104, the bracket drives the cover plate 104 to move towards the position where the cover plate is retracted to the door body 100, and when the cover plate 104 exposes the handle slot 102 to the outside, the bracket is in the pressing state; the reset state refers to a state in which the cover plate 104 is driven by the bracket to be switched from a state of being retracted in the door body 100 to a state of being flush with the outer surface of the door body 100, and at this time, the bracket is in the reset state.

In an embodiment of the present invention, the reset element 106 may be mounted in the seat 124 or on the stand, and the reset element 106 is used for driving the stand to switch from the pressing state to the resetting state.

According to one embodiment of the invention, the support comprises a first rotating support 108 and a second rotating support 110. A first end of the first rotating bracket 108 is hinged to the support 124, and a second end of the first rotating bracket 108 is hinged to the cover plate 104; a first end of the second rotating bracket 110 is hinged to the support 124, and a second end of the second rotating bracket 110 is hinged to the cover plate 104; the reset member 106 is adapted to drive the first rotating bracket 108 and/or the second rotating bracket 110, so that the cover plate 104 moves in a direction perpendicular to the door body 100.

Referring to fig. 10, the first rotating bracket 108 and the second rotating bracket 110 together constitute a bracket in an embodiment of the present invention. A first end of the first rotating bracket 108 and a first end of the second rotating bracket 110 are respectively hinged to the support 124, and a second end of the first rotating bracket 108 and a second end of the second rotating bracket 110 are respectively hinged to the cover plate 104. Thus, the cover plate 104 may act against the support 124 under the hinging action of the first and second

rotational supports

108, 110.

The restoring member 106 may be coupled to the first rotating bracket 108 or the second rotating bracket 110, respectively, or the restoring member 106 may be coupled to the first rotating bracket 108 and the second rotating bracket 110. Through the drive of piece 106 that resets, can drive first runing rest 108 and/or second runing rest 110 and rotate, and then can realize driving the purpose of apron 104 for the action of support 124. In the embodiment of the present invention, the first rotating bracket 108 and the second rotating bracket 110 can drive the cover plate 104 to move along a direction perpendicular to the door body 100, and it can be understood that the cover plate 104 can translate relative to the door body 100 in a direction perpendicular to the door body 100.

According to one embodiment of the present invention, the first rotational support 108 includes a first drive shaft 112, a first driven shaft 114, and a first transition joint 116; the second rotational support 110 includes a second drive shaft 118, a second driven shaft 120, and a second transition piece 122. Two ends of the first driving shaft 112 are hinged to the support 124, two ends of the first driven shaft 114 are hinged to the cover plate 104, and the first transition connecting piece 116 is connected between the first driving shaft 112 and the first driven shaft 114; the second driving shaft 118 is hinged at both ends to the support 124, the second driven shaft 120 is hinged at both ends to the cover plate 104, and the second transition joint 122 is connected between the second driving shaft 118 and the second driven shaft 120.

In other words, referring to fig. 10, 12 and 16, two ends of the first driving shaft 112 and two ends of the second driving shaft 118 are respectively hinged to the support 124, and two ends of the first driven shaft 114 and two ends of the second driven shaft 120 are respectively hinged to the cover plate 104. In order to improve the connection stability between the first driving shaft 112 and the first driven shaft 114, a first transition joint 116 is connected between the first driving shaft 112 and the first driven shaft 114, and correspondingly, a second transition joint 122 is connected between the second driving shaft 118 and the second driven shaft 120.

It should be noted that, when the reset unit 106 is connected to only the first driving shaft 112 of the first rotating bracket 108, the first driven shaft 114, the second driving shaft 118 and the second driven shaft 120 may be provided with a middle cut-off pattern, and it is only necessary to set the length of the first driving shaft 112 to be equal to the width of the support 124.

Referring to fig. 12, 14 and 16, fig. 12 and 16 show a hinge point of the first driving shaft 112 and the support 124, a hinge point of the second driving shaft 118 and the support 124, a hinge point of the first driven shaft 114 and the cover plate 104, and a hinge point of the second driven shaft 120 and the cover plate 104, which are connected in sequence to form a parallelogram. Since the hinge point of the first driving shaft 112 and the support 124 and the hinge point of the second driving shaft 118 and the support 124 are fixed points, and the relative distance between the two hinge points and the inclination angle of the connecting line of the two hinge points are also fixed, the distances between the hinge point of the first driven shaft 114 and the cover plate 104 and the hinge point of the second driven shaft 120 and the cover plate 104 are also equal, and the connecting line between the hinge point of the first driven shaft 114 and the cover plate 104 and the hinge point of the second driven shaft 120 and the cover plate 104 is also parallel to the connecting line between the hinge point of the first driving shaft 112 and the support 124 and the hinge point of the second driving shaft 118 and the support 124, so that the cover plate 104 can realize the up-and-down translation as shown in fig. 12 or fig. 16 along the direction perpendicular to the door. It should be noted that, as shown in fig. 14, in the process of moving the cover plate 104 from the position covering the handle groove 102 to the position avoiding the handle groove 102, the cover plate 104 translates to the left side as shown in fig. 14 for a distance of about 1 mm to 3 mm, then translates to the right side as shown in fig. 14 for a distance of about 1 mm to 3 mm, and finally moves to the position avoiding the handle groove 102 as shown in fig. 16. Similarly, in the process of moving the cover plate 104 from the position avoiding the handle groove 102 to the position shielding the handle groove 102, the cover plate 104 translates to the left side as shown in fig. 14 for a distance of about 1 mm to 3 mm, then translates to the right side as shown in fig. 14 for a distance of about 1 mm to 3 mm, and finally moves to the position shielding the handle groove 102 as shown in fig. 12.

According to one embodiment of the present invention, the first transition piece 116 is adapted to be positioned on the first driving shaft 112 and/or the first driven shaft 114 by a first limit structure; the second transition piece 122 is adapted to be positioned on the second drive shaft 118 and/or the second driven shaft 120 via a second stop feature.

In the embodiment of the present invention, in order to avoid axial play of the first transition joint 116 relative to the first driving shaft 112 and/or the first driven shaft 114, two first positioning blocks may be respectively disposed on the first driving shaft 112 and the first driven shaft 114, a first end of the first transition joint 116 may be connected between the two first positioning blocks on the first driving shaft 112, and a second end of the first transition joint 116 may be connected between the two first positioning blocks on the first driven shaft 114. Of course, in some other embodiments, only two first positioning blocks may be disposed on the first driving shaft 112 or the first driven shaft 114, and the first transition joint 116 is connected between the two first positioning blocks, so as to achieve the purpose of preventing the first transition joint 116 from axially shifting relative to the first driving shaft 112 or the first driven shaft 114.

Similarly, two second positioning blocks may be respectively disposed on the second driving shaft 118 and the second driven shaft 120, a first end of the second transition connection element 122 may be connected between the two second positioning blocks on the second driving shaft 118, and a second end of the second transition connection element 122 may be connected between the two second positioning blocks on the second driven shaft 120. Of course, in other embodiments, two second positioning blocks may be disposed on the second driving shaft 118 or the second driven shaft 120, and the second transition joint 122 is connected between the two second positioning blocks, so as to achieve the purpose of preventing the second transition joint 122 from axially shifting relative to the second driving shaft 118 or the second driven shaft 120.

Of course, in other embodiments, the positions of the first and

second transition pieces

116, 122 may be limited in other manners, such as by providing a positioning pin, a positioning boss, etc. on the first and/or

second drive shafts

112, 118.

Referring to fig. 12, 14 and 16, in consideration of the spatial layout, the first transition piece 116 and the second transition piece 122 are both bent toward the inner surface of the door body 100, and accordingly, a receiving space into which the bent portion of the first transition piece 116 and the bent portion of the second transition piece 122 can enter is formed on the support 124. The width of the first transition joint 116 and the width of the second transition joint 122 do not need to be equal to the length of the first driving shaft 112 and the second driving shaft 118, and may be set to connect the first driving shaft 112 and the first driven shaft 114 and the second driving shaft 118 and the second driven shaft 120. Additionally, in some embodiments of the present invention, the positions of first transition piece 116 and second transition piece 122 in the spatial width direction are staggered to avoid interference between the two during rotation.

To limit the escape of first transition piece 116 and/or second transition piece 122 from seat 124, first transition piece 116 and/or second transition piece 122 is adapted to be retained to seat 124 by the slot sidewalls of handle slot 102.

Referring to fig. 12, the pull tab slot 102 is a slot-like structure formed at the edge of the support 124, whereby the slot sidewall below the pull tab slot 102 as shown in fig. 12 serves as a limit structure for preventing the first transition piece 116 and the second transition piece 122 from being pulled out of the support 124. In other words, when the bracket is switched to the reset state, the side of the first transition joint 116 facing the outer side surface of the door body 100 and the side of the second transition joint 122 facing the outer side surface of the door body 100 can abut against the groove sidewall below the handle groove 102 as shown in fig. 12, so that the first transition joint 116 and the second transition joint 122 can be prevented from coming off from the support 124, and accordingly, the first rotating bracket 108 and the second rotating bracket 110 are prevented from coming off from the support 124. Here, the slip-out means that the connection positions of the first transition piece 116 and the first driven shaft 114 and the second transition piece 122 and the second driven shaft 120 protrude from the outer surface of the door body 100.

Several ways of arranging the reset element 106 according to the embodiment of the present invention are described below:

the setting mode is as follows:

according to an embodiment of the present invention, the reset unit 106 includes a motor, and the motor is mounted to the door body 100 and is connected to the first driving shaft 112 and/or the second driving shaft 118.

For example, in this arrangement, the motor may be connected to the first driving shaft 112, so that when the door 100 is in the closed state, the user may press the cover plate 104 to switch the bracket from the reset state to the pressed state, and at this time, the user may buckle the handle slot 102 to open the door 100. When the door body 100 is opened or the door body 100 is closed again, the motor can drive the first driving shaft 112 to rotate, and then drive the first rotating bracket 108 to switch from the pressing state to the resetting state, and meanwhile, the second rotating bracket 110 is driven by the first rotating bracket 108 to synchronously switch from the pressing state to the resetting state.

Of course, the motor may also be connected to the second driving shaft 118 to drive the second driving shaft 118 by the motor, so that the second rotating bracket 110 is switched from the pressed state to the reset state. Alternatively, two motors may be provided, which are connected to the first drive shaft 112 and the second drive shaft 118, respectively.

In addition, in order to improve the automation degree of the door assembly, a detection member, such as a proximity switch, an infrared switch, etc., may be further provided on the door body 100. Therefore, after the user opens the door body 100 and leaves, the representation user has finished opening the door body 100, at this moment, the detection piece can generate a detection signal for controlling the action of the reset piece 106, and the reset piece 106 can drive the first rotating bracket 108 and/or the second rotating bracket 110 to return to the reset state based on the detection signal and enable the cover plate 104 to shield the handle slot 102, so that the door body 100 can return to a flat and simple state.

The setting mode is two:

according to an embodiment of the present invention, the reset element 106 includes an elastic element, the elastic element is sleeved on the first driving shaft 112, and two ends of the elastic element respectively abut against the door body 100 and the first transition connecting element 116; or the elastic element is sleeved on the second driving shaft 118, and two ends of the elastic element are respectively abutted against the door body 100 and the second driving shaft 118 connecting plate.

In this arrangement, referring to fig. 9, 10, 12 and 16, the elastic member may be a torsion spring, the torsion spring is sleeved on the first driving shaft 112, and two ends of the torsion spring respectively abut against the support 124 and one side of the first transition connecting piece 116 facing the inner surface of the door body 100. Alternatively, a torsion spring may be sleeved on the second driving shaft 118, and two ends of the torsion spring respectively abut against the support 124 and one side of the second transition piece 122 facing the inner surface of the door body 100.

For example, when the door body 100 is in the closed state, the user can press the cover plate 104 to switch the support from the reset state to the pressing state, and at this time, the user can fasten the handle slot 102 to open the door body 100, and at the same time, the torsion spring is screwed. When the user leaves or closes the door body 100, the torsion spring can drive the first driving shaft 112 to rotate under the action of the self torsion restoring force, so as to drive the first rotating bracket 108 to be switched from the pressing state to the resetting state, and meanwhile, the second rotating bracket 110 is synchronously switched from the pressing state to the resetting state under the drive of the first rotating bracket 108.

The setting mode is three:

according to an embodiment of the present invention, the reset element 106 includes a magnetic element, the magnetic element is mounted to the door body 100, and the magnetic element is adapted to drive the rack to switch from the pressed state to the reset state when the rack is in the pressed state.

In this arrangement, a magnetic member, such as an electromagnet, may be provided on the support 124.

Thus, when the door body 100 is in the closed state, the user can press the cover plate 104 to switch the bracket from the reset state to the pressed state, and at this time, the user can buckle the handle slot 102 to open the door body 100. When the user leaves or closes the door body 100, the detection piece can generate a detection signal for controlling the action of the reset piece 106, the electromagnet is powered on to generate magnetism based on the detection signal, and the electromagnet can generate an adsorption force on the first rotating bracket 108 and/or the second rotating bracket 110 to drive the first rotating bracket 108 and/or the second rotating bracket 110 to be switched to the reset state from the pressing state.

As shown in fig. 10 and 17 to 20, according to an embodiment of the present invention, the door assembly further includes a locking device including a locking seat 126 and a latching post 128, the locking seat 126 being disposed at one of the seat 124 and the cover plate 104, the latching post 128 being disposed at the other of the seat 124 and the cover plate 104, the locking seat 126 cooperating with the latching post 128 to lock or unlock the cover plate 104.

For example, the locking seat 126 may be disposed on the support 124 and the locking post 128 may be disposed on the side of the cover plate 104 facing the support 124. In addition, the locking seat 126 and the locking post 128 are disposed opposite to each other in order to ensure the locking seat 126 and the locking post 128 are properly engaged. The locking device may use an elastic self-locking device, and after the user presses the cover plate 104 to a certain position, the locking pin 128 disposed on the cover plate 104 can be clamped to the locking seat 126 of the elastic self-locking device, so as to lock the cover plate 104. At this time, the cover plate 104 does not rebound, that is, the cover plate 104 can be stably kept in a pressed state, and the user can buckle the handle slot 102 to open the door body 100, and in this process, the cover plate 104 does not rebound, so that the situation that the cover plate 104 clamps the hand of the user is avoided.

When the cover plate 104 needs to be ejected, the locking posts 128 on the cover plate 104 can be disengaged from the locking seats 126 by pressing the cover plate 104 again, and at this time, the locking posts 128 are disengaged from the locking seats 126 of the elastic self-locking device. The first rotating bracket 108 and/or the second rotating bracket 110 can be switched from the pressing state to the reset state by the reset element 106.

According to an embodiment of the present invention, the support 124 is provided with a mounting groove 130, and the locking seat 126 or the clip 128 is mounted in the mounting groove 130.

Referring to fig. 10, in order to prevent the position of the locking seat 126 or the clip 128 from interfering with the cover plate 104, a mounting groove 130 is formed on the support 124, and the locking seat 126 or the clip 128 is mounted in the mounting groove 130. For example, the locking seat 126 may be disposed in the mounting groove 130, such that when the cover plate 104 is pressed, the locking pin 128 of the cover plate 104 can be clamped to the locking seat 126 in the mounting groove 130, thereby preventing the mounting position of the locking seat 126 from interfering with the cover plate 104.

According to the storage cabinet provided by the embodiment of the second aspect of the invention, by arranging the door assembly, on the premise that the door body 100 is convenient to open and close, when the door body 100 is in a closed state, the surface of the door body 100 is smooth and concise.
