[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0021] The terms "first", "second", etc. are used only for the purpose of description and are not to be interpreted as indicating or implying relative importance or a number of indicated technical features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly specified. In addition, the terms "comprise" and "have" and any variations thereof are intended to cover exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units not listed, or optionally also includes other steps or units inherent to the process, method, product or device.

[0022] As shown in Figure 1 , Figure 2 and Figure 3 , the present application provides a cover device 10 for use with a concealed handle 21. Specifically, in the embodiments of the present application, the cover device 10 is applied to a door body 20 of a refrigerator or a storage box, for providing a user with a gripping point to open or close the door body 20, and of course the cover device 10 of the present application can also be applied to a door body 20 of other objects provided with a concealed handle 21.

[0023] The concealed handle 21 is a pull groove structure provided inside the door body 20 and can be used for gripping, and thus compared with a handle protruding on the surface of the door body 20, the concealed handle 21 can ensure that the surface of the door body 20 is simple and flat, so as to improve the aesthetic degree of the door body 20. While the concealed handle 21 is provided on the door body 20, an operation space for a human hand to operate is also needed to be reserved on the door body 20 to realize the opening action. The cover device 10 is provided in the operation space, and when opening the door, the cover body 200 of the cover device 10 moves inward relative to the surface of the door body 20, so as to expose the concealed handle 21 relative to the cover body 200, so that the operating hand of a user can extend into the area where the concealed handle 21 is located through the operation space and hold the concealed handle 21, to realize the opening and closing actions.

[0024] For example Figure 1 , Figure 2 and Figure 3As shown, in the embodiment of the present application, the concealed handle 21 is arranged at the end of the door body 20. Specifically, the door body 20 comprises a door main body 22 and a mounting portion 23, the mounting portion 23 is connected to the end of the door main body 22 along the height direction x2 of the door main body 22, and the mounting portion 23 is arranged to be recessed relative to the door surface of the door main body 22 along the thickness direction x3 of the door main body 22 to form an operation space. The concealed handle 21 is formed on the end wall of the door main body 22 adjacent to the mounting portion 23 along the height direction x2 and extends along the width direction x4 of the door main body 22. The cover plate device 10 is arranged on the mounting portion 23, the first base 100 of the cover plate device 10 is fixed relative to the mounting portion 23, and the cover plate is arranged to be movable relative to the first base 100 in the operation space along the thickness direction x3 to expose the concealed handle 21 relative to the cover body 200, so that the user's operating hand can extend into the area where the concealed handle 21 is located through the operation space and hold the concealed handle 21 to realize the door opening and closing actions.

[0025] Of course, in other embodiments, the arrangement position of the concealed handle 21 on the door body 20 can be arranged according to actual needs, and here the embodiment in which the concealed handle 21 is arranged at the end of the door body 20 is mainly described in detail for the cover plate device 10 of the present application.

[0026] As shown in Figure 4 , Figure 5 and Figure 6 , the cover plate device 10 comprises a first base 100, a cover body 200, a connecting assembly 300, an elastic reset member 400, a first damper 500 and a second damper 600. The first base 100 is fixed relative to the concealed handle 21. The connecting assembly 300 connects the cover body 200 and the first base 100, so that the cover body 200 can move from a first position to a third position through a second position under the action of external pressing force, wherein in the first position, the cover body 200 covers the concealed handle 21, and in the third position, the concealed handle 21 is exposed relative to the cover body 200. The elastic reset member 400 is connected with the connecting assembly 300 and is used to reset the cover body 200 after the external pressing force is cancelled, and the reset process of the cover body 200 comprises a first reset section between the third position and the second position and a second reset section between the second position and the first position. The first damper 500 and the second damper 600 are respectively connected with the connecting assembly 300, in the first reset section, the first damper 500 and the second damper 600 jointly provide damping force for the cover body 200, and in the second reset section, the second damper 600 alone provides damping force for the cover body 200.

[0027] Specifically, the first base 100 provides a support for the cover 200, and the cover 200 is connected to the first base 100 through the connecting assembly 300. The base can be a part of the extended structure of the door body 20 or an independent component assembled on the door body 20. In the embodiment of the present application, the first base 100 is an independent component assembled on the mounting portion 23 of the door body 20, and the first base 100 is fixedly connected to the mounting portion 23 to keep relative fixation with the hidden handle 21.

[0028] The cover 200 is a manual device driven by external pressing force and reset by the elastic reset member 400. The cover plate is arranged to move from the first position to the third position through the second position under the action of external pressing force to expose the hidden handle 21 relative to the cover 200, so that the user's operating hand can extend into the area where the hidden handle 21 is located through the operation space and hold the hidden handle 21 to realize the opening and closing actions. The elastic reset member 400 is a component for providing a reset force for the cover 200. The elastic reset member 400 is connected to the connecting assembly 300. During the movement of the cover 200 from the first position to the third position, the cover 200 drives the elastic reset member 400 through the connecting assembly 300. The elastic reset member 400 stores elastic potential energy, and after the external pressing force is cancelled, the elastic reset member 400 generates a reset force to push the cover 200 from the third position to the first position through the connecting assembly 300, so that the cover 200 can hide the hidden handle 21 and smoothly fit the surface of the door body 20.

[0029] The first damper 500 and the second damper 600 are components for providing damping force, and the first damper 500 and the second damper 600 are connected with the connecting assembly 300 respectively. The first reset section is the stroke section of the cover 200 from the third position to the second position, that is, the initial section of the cover 200 in the reset process. Therefore, after the external pressing force is cancelled, if the moving speed of the cover 200 in the first reset section is too fast, the user's hand will not have enough time to move away from the cover 200, thereby increasing the probability of the cover 200 pinching the hand, and thus affecting the use experience of the refrigerator. The second reset section is the stroke section of the cover 200 from the second position to the first position. When the cover 200 is reset to the first position, the cover 200 needs to stop moving under the pulling of the connecting assembly 300. If the moving speed of the cover 200 in the second reset section is too fast, the interaction force between the cover 200 and the connecting assembly 300 will be larger when the cover 200 is reset to the first position, thereby increasing the noise of the cover 200 when the cover 200 is reset to the first position, and thus affecting the use experience of the refrigerator. Therefore, in the embodiment of the present application, the cover 200 is connected with the first damper 500 and the second damper 600 through the connecting assembly 300. In the first reset section, the first damper 500 and the second damper 600 jointly provide damping force for the cover 200, so that the cover 200 moves at a first moving speed which is slow enough, thereby effectively reducing the probability of the cover 200 pinching the hand, and thus effectively improving the use experience of the refrigerator. In the second reset section, the second damper 600 alone provides damping force for the cover 200, so that the cover 200 can be reset at a second moving speed which is faster than the first moving speed in the second reset section, thereby shortening the time required for the reset of the cover 200, and also enabling the cover 200 to reset to the first position in a relatively gentle movement manner, thereby effectively reducing the noise of the cover 200 when the cover 200 is reset to the first position, effectively reducing the working noise of the cover device 10, and effectively improving the use experience of the refrigerator.

[0030] Optionally, the elastic reset member 400 can be a spring or the like elastic member.

[0031] As Figure 4 , Figure 5 and Figure 6As shown, in some embodiments, the cover plate device 10 further includes a transmission assembly 700, which is disposed on the first base 100. The transmission assembly 700 moves along the first base 100 as the cover 200 moves between the first position and the third position. In the first reset section, the connecting assembly 300 is connected to the first damper 500 and the second damper 600 respectively through the transmission assembly 700. Based on this, in the first reset section, the connecting assembly 300 can be connected to both the first damper 500 and the second damper 600 through the transmission assembly 700, so that the first damper 500 and the second damper 600 can jointly provide damping force to the cover 200 through the transmission assembly 700, thereby effectively reducing the probability of the cover 200 pinching the hand. In the second reset phase, the connecting component 300 is connected to the second damper 600 via the transmission component 700 and disconnected from the first damper 500. Based on this, in the second reset phase, the connecting component 300 is connected to the second damper 600 only via the transmission component 700, so that the second damper 600 can provide damping force to the cover 200 independently.

[0032] The transmission component 700 is mounted on the first base 100 and moves along the first base 100 as the cover 200 moves between the first and third positions. This effectively reduces the space occupied by the transmission component 700, allowing the transmission component 700 to make transmission connections between the cover plate and the elastic reset member 400, the first damper 500 and the second damper 600 within a relatively small installation space.

[0033] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the cover plate device 10 further includes a second base 800 and a third base 900, which are respectively disposed on both sides of the first base 100, and the second base 800 and the third base 900 remain relatively fixed relative to the concealed handle 21. The first base 100, the second base 800, and the third base 900 can be detachably fixed to the door body 20, such as by screw connection, to achieve relative fixation with the concealed handle 21.

[0034] The transmission assembly 700 comprises a first transmission member 710, a second transmission member 720 and an adapter member 730. The first transmission member 710 is slidingly supported on the first base 100 and connected with the connecting assembly 300. The first transmission member 710 comprises a first end and a second end which are arranged in a spaced manner. The first end of the first transmission member 710 is arranged adjacent to the second base 800, and the second end of the first transmission member 710 is arranged adjacent to the third base 900. The second transmission member 720 is detachably connected with the first end of the first transmission member 710 and slidingly supported on the second base 800. The elastic return member 400 and the second damper 600 are arranged on the third base 900 respectively. The adapter member 730 is connected with the second damper 600 and the elastic return member 400 and further detachably connected with the second end of the first transmission member 710.

[0035] During the resetting process of the cover 200, the elastic return member 400 drives the first transmission member 710 through the adapter member 730 to make the first transmission member 710 translate on the first base 100. The first transmission member 710 drives the cover 200 through the connecting assembly 300 to reset the cover 200, and drives the first damper 500 through the second transmission member 720 to receive the damping force of the first damper 500.

[0036] Optionally, the second damper 600 is a one-way damper. During the movement of the cover 200 from the first position to the third position, the second damper 600 does not generate damping effect on the cover 200. During the resetting process of the cover 200 from the third position to the first position (including the first resetting section and the second resetting section), the second damper 600 provides damping force for the cover 200.

[0037] Optionally, as shown in Figure 4 , Figure 5 and Figure 6 , the first damper 500 is a gear damper which can rotate relative to the first base 100 around a preset rotation axis. During the first resetting section, the transmission assembly 700 is connected with the first damper 500 in a gear meshing manner, so that the first damper 500 can provide damping force for the cover 200 during the first resetting section. During the second resetting section, the transmission assembly 700 is disconnected from the first damper 500 in the gear meshing manner, so that the first damper 500 stops providing damping force for the cover 200.

[0038] Specifically, the second transmission member 720 is provided with an engagement region (not labeled in the figure) and a non-engagement region (not labeled in the figure), when the cover body 200 is located in the region between the second position and the third position, the engagement region of the second transmission member 720 is coincided with the first damper 500 and is connected with the first damper 500 in a tooth engagement manner, so that the first damper 500 can provide a damping force to the cover body 200 in the first reset section, when the cover body 200 is located in the region between the second position and the first position, the non-engagement region of the second transmission member 720 is overlapped with the first damper 500, and the first transmission member 710 is disengaged from the first damper 500 in a tooth engagement manner, so that the first damper 500 stops providing a damping force to the cover body 200.

[0039] In some embodiments, the first damper 500 is a bidirectional damper, which can provide a damping force to the cover body 200 in the first reset section and in the pressing section of the cover body 200 from the second position to the third position. Specifically, in the pressing section of the cover body 200 from the second position to the third position, the second transmission member 720 is connected with the first damper 500, and the first damper 500 provides a damping force to the cover body 200, based on which the impact that may be generated when the cover body 200 moves from the second position to the third position can be reduced, so that the cover body 200 can move from the second position to the third position in a relatively gentle manner, thereby effectively reducing the noise of the cover plate device 10 and effectively improving the user experience of the refrigerator.

[0040] As shown in Figure 4 , Figure 5 and Figure 6 , in some embodiments, the cover plate device 10 includes a plurality of sets of connection assemblies 300 arranged along the width direction x1 of the cover body 200, each set of connection assemblies 300 is connected with the first transmission member 710, the cover body 200 and the first base 100, respectively, so that the stability of the movement of the cover body 200 relative to the first base 100 can be effectively improved. The number of connection assemblies 300 can be set according to actual design requirements, for example, in the embodiments of the present application, the number of connection assemblies 300 is three, in other embodiments, the number of connection assemblies 300 can also be two, four or five, which is not limited herein. In the embodiments of the present application, the width direction x1 of the cover body 200 is parallel to the width direction x4 of the door body 22. Of course, due to the spatial position relationship of the cover body 200 associated with the hidden handle 21, in other embodiments, the hidden handle 21 can also be arranged to extend along the height direction x2 of the door body 22, at this time, the width direction x1 of the cover body 200 should be parallel to the height direction x2 of the door body 22.

[0041] As shown in Figure 4 and Figure 5As shown, in some embodiments, the connecting assembly 300 includes a first connecting rod 320 and a second connecting rod 310. The first end of the first connecting rod 320 is hinged to the cover 200, and the second end of the first connecting rod 320 is hinged to the first transmission member 710. The first end of the second connecting rod 310 is hinged to the first base 100, and the second end of the second connecting rod 310 is hinged at a predetermined position between the first and second ends of the first connecting rod 320. Thus, the first connecting rod 320 and the second connecting rod 310 cooperate through the above-described connection relationship, allowing the cover 200 to remain connected to the first base 100 while also enabling the cover 200 to move relative to the first base 100.

[0042] like Figure 6 , Figure 5 and Figure 6 Figure 4 Figure 5 Figure 6 As shown, in some embodiments, the connecting component 300 is configured such that the movement trajectory of the cover 200 is a linear movement trajectory, thereby enabling the cover 200 to move relative to the first base 100 in a more limited space, thereby effectively reducing the space occupancy rate of the cover device 10.

[0043] Specifically, there is a first interval distance between the first end of the first link 320 and the second end of the second link 310, a second interval distance between the second ends of the first link 320 and the second end of the second link 310, and a third interval distance between the first and second ends of the second link 310. The first, second, and third interval distances are all equal. Based on this, the connecting assembly 300 composed of the first link 320 and the second link 310 can ensure a stable connection between the cover 200 and the first base 100, while also allowing the cover 200 to move linearly relative to the first base 100, thus making the movement trajectory of the cover 200 a linear trajectory. For example, in this embodiment, under the constraint of the connecting assembly 300, the cover 200's movement trajectory is a linear trajectory parallel to the thickness direction x3.

[0044] This application also proposes a refrigerator that includes the cover device 10 described in any of the above embodiments.

[0045] In summary, the cover device 10 of the present application is provided with the first damper 500 and the second damper 600, and the cover body 200 is connected with the first damper 500 and the second damper 600 through the connecting assembly 300. In the first reset section, the first damper 500 and the second damper 600 jointly provide the cover body 200 with damping force, so that the cover body 200 moves at a first moving speed which is slow enough in the first reset section, thereby effectively reducing the probability of the cover body 200 being pinched, and effectively improving the use experience of the refrigerator. In the second reset section, the second damper 600 alone provides the cover body 200 with damping force, so that the cover body 200 can reset at a second moving speed which is relatively faster than the first moving speed in the second reset section, thereby shortening the time required for the cover body 200 to reset, and also enabling the cover body 200 to reset to the first position in a relatively gentle movement manner in the second reset section, thereby effectively reducing the noise when the cover body 200 resets to the first position, effectively reducing the working noise of the cover device 10, and effectively improving the use experience of the refrigerator.

[0046] It is worth noting that the drawings herein are only used to show the structural relationship and connection relationship of the utility model product of the present application, and do not limit the specific structural size of the utility model product of the present application.

[0047] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
