[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, inside, outside, top, bottom, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] In the description of the present utility model, "a plurality" refers to two or more than two. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] When the door of refrigeration equipment such as refrigerators is closed, it is easy for it to collide with the cabinet and generate a large impact force, which will cause noise and shaking, resulting in a poor user experience. In addition, it is also easy for the door and cabinet to be damaged due to excessive impact force.

[0034] In order to reduce the impact force between the door body and the box body of the refrigeration equipment, in the related technology, a damper that can provide damping is arranged between the box body and the door body of the refrigeration equipment. The existing damper is generally a pneumatic damping rod or a hydraulic damping rod. However, the pneumatic damping rod or the hydraulic damping rod has a complex structure and has extremely high requirements for sealing. It is easy for the sealing to be poor and cause gas or liquid leakage, which in turn leads to damping failure. In addition, the refrigeration equipment belongs to a low-temperature environment. For example, the temperature in the freezing chamber of some refrigeration equipment may even be lower than minus 25°C, and the liquid in the hydraulic damping rod has poor fluidity in a low-temperature environment, which will cause the damping effect of the hydraulic damping rod to be greatly reduced, or even completely lose the damping function, seriously affecting the normal use of the refrigeration equipment.

[0035] Therefore, the utility model proposes a refrigeration device, which can effectively improve the above problems.

[0036] Reference below Figures 1 to 7 A refrigeration device according to an embodiment of the utility model is described.

[0037] like Figures 1 to 7 As shown, the refrigeration device according to the embodiment of the utility model includes a box body 100, a door body 200 and a damping assembly 300.

[0038] For example, a storage cavity may be provided in the box body 100, and the storage cavity may include a refrigeration cavity and a freezing cavity, etc. A take-in and put-out opening may be provided at the front end of the box body 100, and the take-in and put-out opening is used for taking food in and out.

[0039] The door body 200 is movably connected to the box body 100. For example, the door body 200 can be slidably installed on the box body 100 along the front-to-back direction of the box body 100. When the door body 200 slides backward, the access opening at the front end of the box body 100 can be closed. When the door body 200 slides forward, the access opening at the front end of the box body 100 can be opened, so as to facilitate the access to and placement of food. Of course, the door body 200 can also be other movement modes. For example, the door body 200 can also be rotatably installed on the box body 100 around a vertical axis. When the door body 200 rotates toward the box body 100, the access opening at the front end of the box body 100 can be closed. When the door body 200 rotates away from the box body 100, the access opening at the front end of the box body 100 can be opened.

[0040] The damping assembly 300 includes a magnetic body 301 and a conductive body 302. The magnetic body 301 can be disposed on the door body 200. The magnetic body 301 can be a permanent magnet or an electromagnet. Correspondingly, the conductive body 302 can be disposed on the box body 100, for example, on the inner wall of the box body 100. Of course, the magnetic body 301 can also be disposed on the box body 100, and correspondingly, the conductive body 302 can be disposed on the door body 200. During the process of the door body 200 closing the box body 100, the magnetic body 301 and the conductor 302 can move relative to each other. For example, the magnetic body 301 and the conductor 302 can approach each other. When the door body 200 moves to a preset position along the direction of closing the box body 100 and continues to move, the magnetic body 301 can cut the magnetic flux lines of the conductor 302. The conductor 302 can generate an induced magnetic field in response to the relative movement of the magnetic body 301 and the conductor 302 due to electromagnetic induction. The induced magnetic field is opposite to the magnetic pole of the magnetic field of the magnetic body 301 itself, and then the conductor 302 can generate an electromagnetic force. The electromagnetic force can hinder the relative movement of the magnetic body 301 and the conductor 302, thereby providing a damping force for the door body 200, avoiding excessive impact force between the door body 200 and the box body 100 to generate noise and shaking, thereby improving user experience and avoiding damage to the door body 200 and the box body 100 due to excessive impact force.

[0041] According to the refrigeration equipment of the embodiment of the utility model, the conductor 302 can generate electromagnetic force in response to the relative movement of the magnetic body 301 and the conductor 302 due to electromagnetic induction, thereby providing damping force to the door body 200. Not only is the structure simple, but also the problem of damping failure will not occur due to poor sealing or low temperature environment. The damping effect is stable and the practicality is better. In addition, the magnetic body 301 and the conductor 302 of the damping assembly 300 can provide damping for the door body 200 without contacting each other, thereby avoiding wear of the magnetic body 301 and the conductor 302, thereby extending the service life of the damping assembly 300, thereby extending the service life of the refrigeration equipment.

[0042] It should be noted that the electromagnetic force generated by the conductor 302 is positively correlated with the speed of relative movement between the magnetic body 301 and the conductor 302, that is, the damping force provided to the door body 200 is positively correlated with the movement speed of the door body 200. The greater the movement speed of the door body 200, the better the damping effect provided to the door body 200. Moreover, after the door body 200 is subjected to the damping force, the movement speed of the door body 200 will gradually decrease, and then the damping force provided to the door body 200 will also gradually decrease, so that the door body 200 can be closed normally, and there will be no situation where the damping force on the door body 200 is too large, causing the door body 200 to be difficult to close. The door body 200 mentioned in this embodiment moves to a preset position along the direction of closing the box body 100, which means that the door body 200 moves to a position where the magnetic body 301 can cut the magnetic flux lines of the conductor 302. At this position, the door body 200 is close to the box body 100.

[0043] It can be understood that the refrigeration equipment can be a refrigerator, a display cabinet, a freezer, a fresh-keeping cabinet, etc.

[0044] refer to Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the conductor 302 is configured as a coil, and when the door body 200 closes the box body 100, the magnetic body 301 can move relative to the coil until it is at least partially inserted into the coil.

[0045] For example, the coil can be a closed coil, and the coil can be enclosed to form a circular hole-shaped plug-in, and the axial direction of the plug-in can be the movement direction of the door body 200. Along the movement direction of the door body 200, the projection of the magnetic body 301 can coincide with the projection of the plug-in, and in the process of the door body 200 closing the box body 100, the magnetic body 301 can be gradually inserted into the plug-in formed by the coil, and then can cut the magnetic flux lines of the coil, and the coil then generates an induced current, and the induced current generates an induced magnetic field, and the coil thereby generates an electromagnetic force, and the electromagnetic force can cause the magnetic body 301 and the coil to repel each other, thereby providing a damping force for the door body 200. In this embodiment, the conductor 302 is set as a coil, which is not only simple in structure, but also convenient for the magnetic body 301 to cut the magnetic flux lines, and the effect of the conductor 302 generating electromagnetic force is better, thereby providing a better damping effect for the door body 200.

[0046] It should be noted that, in order to match the coil, the magnetic body 301 can be set to a cylindrical shape, the axial direction of the magnetic body 301 can be parallel to the axial direction of the jack formed by the coil, and the axis of the magnetic body 301 can overlap or have a certain offset with the center line of the jack formed by the coil. Of course, the magnetic body 301 can also be in other shapes, for example, it can be block-shaped. In addition, the magnetic body 301 can be partially inserted in the coil, can be inserted in the coil as a whole, or can pass through the coil as a whole.

[0047] refer to Figure 4 and Figure 5 As shown, in a further embodiment of the utility model, the refrigeration device further includes a power module, the coil is connected to the power module, and the power module is configured to be able to adjust the value and / or direction of the current input to the coil. For example, the power module can be arranged on the box 100 or the door 200 of the refrigeration device, the power module can be provided with a controller, and the power module can adjust the value and / or direction of the current input to the coil through the controller.

[0048] In this embodiment, in addition to generating an induced current in response to the relative movement between the magnetic body 301 and the coil, the coil can also input current through the power module. For example, the current input by the power module can be in the same direction as the induced current generated by the coil in response to the relative movement between the magnetic body 301 and the coil, thereby increasing the electromagnetic force generated by the coil to hinder the relative movement between the coil and the magnetic body 301, thereby increasing the damping force on the door body 200, and the power module can adjust the value of the current input to the coil, thereby adjusting the damping effect on the door body 200.

[0049] In addition, the power module can also be configured to adjust the direction of the current input to the coil. For example, when the door body 200 needs to be closed, the direction of the current input by the power module can be opposite to the direction of the induced current generated by the coil in response to the relative movement of the magnetic body 301 and the coil. The current input by the power module is greater than the induced current generated by the coil. The magnetic pole direction of the electromagnetic field generated by the current input by the power module is the same as the magnetic pole direction of the magnetic field of the magnetic body 301 itself, so that the magnetic body 301 can be automatically attracted, thereby attracting the door body 200, and realizing automatic closing of the door body 200. When the door body 200 needs to be opened, the direction of the current input by the power module can be changed, so that the magnetic pole direction of the electromagnetic field generated by the current input by the power module is opposite to the magnetic pole direction of the magnetic field of the magnetic body 301 itself, thereby repelling the magnetic body 301, thereby automatically repelling the door body 200, realizing automatic opening of the door body 200, and realizing the automatic opening and closing function of the refrigeration equipment.

[0050] It should be noted that the power module can be configured to only adjust the value of the current of the input coil, the power module can also be configured to only adjust the direction of the current of the input coil, or the power module can be configured to adjust both the value and direction of the current of the input coil.

[0051] It can be understood that when the coil and the magnetic body 301 cooperate to realize the automatic opening and closing function of the door body 200, the damping effect is no longer provided for the door body 200. If it is necessary to provide a damping effect for the door body 200, the connection between the power module and the coil can be disconnected, or the direction of the current input by the power module is the same as the direction of the induced current generated by the coil in response to the relative movement of the magnetic body 301 and the coil.

[0052] refer to Figure 2 and Figure 4 As shown, in a further embodiment of the utility model, the box body 100 or the door body 200 is provided with a mounting tube 101, and the coil is wound around the mounting tube 101. In the process of the door body 200 closing the box body 100, the magnetic body 301 can move relative to the coil until it is at least partially inserted into the mounting tube 101.

[0053] For example, the mounting tube 101 can be arranged on the inner wall of the box body 100. In this case, the magnetic body 301 is correspondingly arranged on the door body 200. The mounting tube 101 can be a round tube structure. The coil can be wound around the outer wall of the mounting tube 101. The axial direction of the mounting tube 101 can be parallel to the movement direction of the door body 200. Along the movement direction of the door body 200, the projection of the magnetic body 301 can coincide with the projection of the tube hole of the mounting tube 101. In the process of the door body 200 closing the box body 100, the magnetic body 301 can be gradually inserted into the tube hole of the mounting tube 101, and then correspondingly inserted into the coil, so that the magnetic flux lines of the coil can be cut, and the coil generates an electromagnetic force, which can cause the magnetic body 301 and the coil to repel each other, thereby providing a damping force for the door body 200. In this embodiment, the mounting tube 101 is provided, which not only makes it more convenient and stable to install the coil, but also makes it more convenient to insert the magnetic body 301, and has better practicality.

[0054] It should be noted that the mounting tube 101 may also be arranged on the door body 200, in which case the magnetic body 301 is correspondingly arranged on the box body 100. In addition, the coil may also be installed in other suitable ways, which will not be described here. It is understandable that when the magnetic body 301 is arranged in a cylindrical shape, the axial direction of the magnetic body 301 may be parallel to the axial direction of the mounting tube 101, and the axis centerline of the magnetic body 301 may coincide with the axis centerline of the mounting tube 101, and of course, there may be a slight offset. In addition, the magnetic body 301 may be partially inserted into the mounting tube 101, or may be inserted into the mounting tube 101 as a whole, or may be able to pass through the mounting tube 101 as a whole.

[0055] In some embodiments of the utility model, the conductor 302 is set to a tubular structure. In the process of the door body 200 closing the box body 100, the magnetic body 301 can move relative to the conductor 302 to at least partially insert into the conductor 302. In addition to being set as a coil, the conductor 302 can also be set as a tubular structure, for example, it can be set as a copper tube, an aluminum tube or other suitable metal tubular structure capable of conducting electricity. The tubular conductor 302 can also form a closed loop. In the process of the door body 200 closing the box body 100, the magnetic body 301 can move relative to the conductor 302 to gradually insert into the conductor 302, and then can also cut the magnetic flux lines of the conductor 302. The conductor 302 then generates an induced current, and the induced current generates an induced magnetic field. The conductor 302 generates an electromagnetic force, which can cause the magnetic body 301 and the conductor 302 to repel each other, thereby providing a damping force for the door body 200.

[0056] In this embodiment, the conductor 302 is set to a tubular structure, which is not only simple in structure and easy to install, but also convenient for the magnetic body 301 to cut the magnetic lines of force. The electromagnetic induction effect of the conductor 302 is better, and the effect of generating electromagnetic force is better, thereby providing a better damping effect for the door body 200.

[0057] refer to Figure 1 and Figure 4 As shown, in some embodiments of the present utility model, the magnetic body 301 is set as a cylindrical structure, the door body 200 or the box body 100 is provided with an arc-shaped fixing piece 201, and the outer side wall of the magnetic body 301 is connected to the inner side wall of the arc-shaped fixing piece 201. For example, the door body 200 can be provided with a bracket 202, the arc-shaped fixing piece 201 can be arranged on the bracket 202 of the door body 200, the inner side wall of the arc-shaped fixing piece 201 can be matched with the outer side wall of the magnetic body 301, the inner side wall of the arc-shaped fixing piece 201 is attached to the outer side wall of the magnetic body 301, and the inner side wall of the arc-shaped fixing piece 201 and the outer side wall of the magnetic body 301 can be bonded or welded.

[0058] In this embodiment, the magnetic body 301 is configured as a cylindrical structure, which is more convenient when inserted into the coil-shaped conductor 302 or the tubular conductor 302, and has a better effect of cutting the magnetic flux lines of the conductor 302, so that the electromagnetic force generated by the conductor 302 has a better effect. The arc-shaped fixing sheet 201 adapted to the magnetic body 301 is provided, so that the installation of the magnetic body 301 is more convenient and stable.

[0059] It should be noted that the magnetic body 301 may also be in other suitable shapes, and the magnetic body 301 may also be installed in other ways, which will not be described in detail here.

[0060] refer to Figure 7 As shown, in some embodiments of the present invention, the conductor 302 is set as a sheet structure. In the process of the door body 200 closing the box body 100, the magnetic body 301 can pass through one side of the conductor 302 in the thickness direction relative to the conductor 302. In addition to being set as a coil and a tubular structure, the conductor 302 can also be in other shapes, for example, it can also be set as a sheet structure. The sheet-like conductor 302 can also form a closed loop. In the process of the door body 200 closing the box body 100, the path of the magnetic body 301 moving relative to the conductor 302 passes through one side of the conductor 302 in the thickness direction. With this arrangement, the magnetic body 301 can also cut the magnetic flux lines of the conductor 302, and the conductor 302 further generates an induced current, the induced current generates an induced magnetic field, and the conductor 302 generates an electromagnetic force. The electromagnetic force can cause the magnetic body 301 and the conductor 302 to repel each other, thereby providing a damping force for the door body 200.

[0061] In this embodiment, the conductor 302 is set to a sheet structure, which is not only simple in structure and easy to install, but also convenient for the magnetic body 301 to cut the magnetic flux lines. The electromagnetic induction effect of the conductor 302 is better, and the effect of generating electromagnetic force is better, thereby providing a better damping effect for the door body 200.

[0062] refer to Figure 7 As shown, further, the magnetic body 301 is set as a sheet structure, the surface of the magnetic body 301 in the thickness direction is parallel to the surface of the conductor 302 in the thickness direction, and the relative movement direction of the magnetic body 301 and the conductor 302 is parallel to the surface of the conductor 302 in the thickness direction. In this embodiment, the magnetic body 301 is set as a sheet structure parallel to the conductor 302, and the relative movement direction of the magnetic body 301 and the conductor 302 is parallel to the surface of the conductor 302 in the thickness direction, and then when the magnetic body 301 moves relative to the conductor 302, the effect of cutting the magnetic flux lines of the conductor 302 is better, the electromagnetic induction effect of the conductor 302 is better, and the effect of generating electromagnetic force is better, so as to provide a better damping effect for the door body 200.

[0063] It should be noted that, in some other embodiments of the present invention, the relative movement direction of the magnetic body 301 and the conductor 302 may also form a certain angle with the surface of the conductor 302 in the thickness direction, for example, an angle of 5° or 10°.

[0064] refer to Figures 1 to 3 as well as Figure 6 As shown, in some embodiments of the utility model, the box body 100 is installed with a slidable movable rail 102, the door body 200 is provided with a bracket 202, one of the movable rail 102 and the bracket 202 is provided with a slot 103, and the other is provided with a plug-in portion 203, and the plug-in portion 203 is inserted in the slot 103 to realize a detachable connection between the bracket 202 and the movable rail 102.

[0065] For example, the two inner walls of the box body 100 can be provided with guide rails, which extend along the front and rear directions of the box body 100. Two movable rails 102 can be provided and slidably installed on the two guide rails respectively. The sliding direction of the movable rail 102 is the front and rear direction of the box body 100. The movable rail 102 can be provided with a slot 103, for example, two slots 103 can be provided, and the slot 103 can penetrate vertically. The door body 200 can be provided with two brackets 202, and each bracket 202 can be correspondingly provided with two plug-in parts 203. The plug-in parts 203 are inserted into the corresponding slots 103 to realize the installation of the door body 200, which is convenient to install. The movement of the door body 200 can be realized by sliding the movable rail 102, so that the door body 200 can open and close the box body 100. The structure is simple and the operation is convenient. Moreover, the plug-in part 203 is taken out from the top of the slot 103, so that the door body 200 can be disassembled, and it is convenient to disassemble the door body 200.

[0066] It should be noted that the door body 200 may also have other movement modes, for example, it may be rotatably mounted on the box body 100. In addition to being slidably mounted on the box body 100 along the front-back direction, the movable rail 102 may also be slidably mounted on the box body 100 along other suitable directions, which will not be repeated here. In addition, the slot 103 may also be provided on the bracket 202, and correspondingly, the plug-in portion 203 may be provided on the movable rail 102. The movable rail 102 or the bracket 202 may also be provided with one, three or more slots 103, and the bracket 202 or the movable rail 102 may also be correspondingly provided with one, three or more plug-in portions 203. In addition to penetrating vertically, the slot 103 may also penetrate along other suitable directions.

[0067] refer to Figure 6 As shown, in a further embodiment of the utility model, the movable rail 102 is provided with a mounting portion 104, the mounting portion 104 defines a slot 103 that penetrates vertically, the plug-in portion 203 is provided on the bracket 202, and a limiting portion 204 is provided at the bottom end of at least part of the plug-in portion 203, the bracket 202 abuts against the top end of the mounting portion 104, and the plug-in portion 203 can move laterally to a first position in which the limiting portion 204 abuts against the bottom end of the mounting portion 104, and a second position in which the limiting portion 204 can pass through the slot 103.

[0068] For example, the mounting portion 104 may be disposed on one side of the movable rail 102, and the mounting portion 104 may be enclosed with the movable rail 102 to define a slot 103 that penetrates vertically. Of course, the mounting portion 104 itself may define a slot 103 that penetrates vertically. The slot 103 may extend in the front-to-back direction of the box body 100, and a limiting portion 204 may be disposed at the bottom end of the plug-in portion 203 at the rear end of the movable rail 102, and the limiting portion 204 may extend backward to the outside of the plug-in portion 203. When the door body 200 needs to be installed, the plug-in part 203 is inserted into the corresponding slot 103, and the bracket 202 is made to abut the top of the mounting part 104, that is, the bracket 202 is supported on the top of the mounting part 104, and then the plug-in part 203 is moved backward so that the plug-in part 203 is located in the first position. In this case, the limiting part 204 abuts the bottom end of the plug-in part 203. Through the limiting of the limiting part 204 and the bracket 202, the plug-in part 203 can be prevented from moving arbitrarily in the vertical direction, and the plug-in part 203 can be prevented from being arbitrarily detached from the slot 103, thereby making the insertion of the plug-in part 203 more stable, thereby making the installation of the door body 200 more stable. When the door body 200 needs to be removed, the plug-in part 203 is moved forward so that the plug-in part 203 is located in the second position. In this case, the limiting part 204 is located directly below the slot 103. The plug-in part 203 is then moved upward so that the limiting part 204 can be moved upward and pass through the slot 103, thereby realizing the separation of the plug-in part 203 and the slot 103, thereby realizing the disassembly of the door body 200, and facilitating the disassembly of the door body 200.

[0069] It should be noted that the slot 103 may also extend along other horizontal directions, or the bottom ends of all the plug-in portions 203 may be provided with the limiting portion 204 .

[0070] In some embodiments of the present invention, the plug-in portion 203 is connected to the movable rail 102 by a fastener. For example, the plug-in portion 203 may be provided with a first connection hole, and the movable rail 102 may be provided with a second connection hole. When the plug-in portion 203 is inserted into the slot 103, the first connection hole and the second connection hole are aligned, and then the fastener is installed between the first connection hole and the second connection hole. In this embodiment, in addition to the mutual insertion of the bracket 202 and the movable rail 102 through the cooperation of the plug-in portion 203 and the slot 103, the plug-in portion 203 is also connected to the movable rail 102 by a fastener, thereby making the connection between the bracket 202 and the movable rail 102 more stable, thereby making the installation of the door body 200 more stable.

[0071] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
