Description

Technical Field

[0001] The present invention relates to the technical field of storage cabinets, in particular to a door assembly and a storage cabinet. Background Art

[0002] For most storage cabinets with double-door doors, a flip beam is typically required to achieve a seal due to sealing requirements. For example, refrigerators come in a variety of configurations, including double-door, triple-door, and quad-door models. When refrigerators have double-door doors, cold air can easily leak between them. To address this issue, a flip beam is installed on the door body, running along the inner edge of either door. During the opening and closing of the doors, the flip beam rotates along a vertical axis, sealing the gap between the doors and the refrigerator body and door, achieving a heat-insulating effect.

[0003] In the prior art, the tilting beam needs to cooperate with the guide structure of the cabinet's inner shell. The guide structure limits the track so that the tilting beam moves along the guide direction of the track. The guide structure protrudes from the surface of the cabinet, resulting in a complex cabinet structure and a less concise appearance, which is difficult to meet consumer needs. Summary of the Invention

In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0044] Combine Figures 1 to 7As shown, the door assembly is applied to a cabinet (not shown in the figure) having a pair of doors, the pair of doors including a first door assembly and a second door assembly suitable for being opened in pairs, one of the first door assembly and the second door assembly is provided with the turnover beam 100 (the following embodiment takes the first door assembly provided with the turnover beam 100 as an example). The first door assembly and the second door assembly can be switched between a closed state and an open state, when the first door assembly and the second door assembly are in the closed state, the turnover beam 100 is used to close the gap between the first door assembly and the second door assembly.

[0045] Wherein, the cabinet needs to be sealed, and can be used for heat preservation or cold preservation, and the following embodiment takes the cabinet used for cold preservation as an example. The pair of doors can be a pair of left-right parallel doors, a pair of up-down parallel doors or a pair of parallel doors in other directions, and the first door assembly and the second door assembly of the pair of doors are taken as an example of being arranged in left-right parallel, it can be understood that a refrigerator having a pair of left-right parallel doors is taken as an example for description.

[0046] The embodiment of the first aspect of the application provides a door assembly, comprising: a door body and a turnover beam 100, the turnover beam 100 is suitable for being switched between a closed position and a recovery position.

[0047] As shown in Figure 1 and Figure 7 , the turnover beam 100 is in the closed position, corresponding to the first door assembly and the second door assembly being in the closed state, at this time, the turnover beam 100 is used to close the gap between the first door assembly and the second door assembly. In some cases, in the closed position, the turnover beam 100 extends towards the second door assembly, that is, the turnover beam 100 extends out of the side wall of the first door assembly, and the side wall faces the second door assembly. The turnover beam 100 is in the recovery position, corresponding to the first door assembly and the second door assembly being in the open state, at this time, the user needs to open the cabinet, the cabinet is no longer in a sealed state, and the turnover beam 100 in the recovery position (not shown in the figure) is shielded by the first door assembly, avoiding the turnover beam 100 extending out of the side wall to affect the operation of the user. The turnover beam 100 is switched between the closed position and the recovery position by rotating relative to the first door assembly.

[0048] The door body is connected with a connecting part 200, the connecting part 200 is provided with a first guide part; the turnover beam 100 is connected to the connecting part 200, the turnover beam 100 is provided with a first magnetic part 110 and a second guide part, the first magnetic part 110 is suitable for generating a magnetic field force between the second magnetic part 400 of the cabinet body, so as to drive the second guide part to rotate and move along the guide direction of the first guide part, so that the turnover beam 100 is switched from the recovery position to the closed position, and in the closed position, the turnover beam 100 is used to close the gap of the pair of doors.

[0049] The magnetic field force between the first magnetic member 110 and the second magnetic member 400 is either an attractive force or a repulsive force. During the closing process of the door assembly, the distance between the first magnetic member 110 and the second magnetic member 400 decreases, and the attractive force or repulsive force between the first magnetic member 110 and the second magnetic member 400 increases, providing power to the flip beam 100. The flip beam 100 moves along the guide path between the first guide portion and the second guide portion. This guide path is a rotational movement path, which enables the flip beam 100 to switch from the return position to the closed position, thereby enabling the flip beam 100 to close the gap at the opening of the double-leaf door.

[0050] In the door assembly of this embodiment, during the closing process, the first magnetic member 110 cooperates with the second magnetic member 400 in the cabinet to drive the flip beam 100 to move. At the same time, the first guide portion cooperates with the second guide portion to drive the flip beam 100 to rotate a preset angle, directly driving the flip beam 100 to move through the magnetic field force, providing a new driving structure for the flip beam 100. Without the need for a transmission structure, the door assembly has a simpler structure. There is no need to set a guide structure or track on the inner liner 300 of the cabinet. Without the friction of the guide structure, opening and closing is labor-saving, and the cabinet's external structure is simplified, making the cabinet's appearance more concise and beautiful. The number of parts is reduced, and assembly is simple and convenient. The door assembly can be used with any cabinet of the same size, with strong structural versatility, improving the adaptability of the door assembly to the cabinet, and the door assembly is applicable to a variety of cabinets. In addition, no matter what position the double door is in, whether the flip beam 100 is open, closed, or in the middle position, the door can be closed in any way without getting stuck or being damaged by incorrect operation.

[0051] Below, reference Figures 1 to 3 As shown, the first magnetic member 110 is described in conjunction with the second magnetic member 400 .

[0052] It is understandable that if Figure 3 As shown, in the closed position, the side of the first magnetic member 110 facing the second magnetic member 400 is the first magnetic pole 111, and the side of the second magnetic member 400 facing the first magnetic member 110 is the second magnetic pole 410. The first magnetic pole 111 is the same as the second magnetic pole 410, and a repulsive force is generated between the same magnetic poles. The repulsive force between the first magnetic member 110 and the second magnetic member 400 drives the flip beam 100 to move, so that the flip beam 100 moves back to the second magnetic member 400.

[0053] Different from the above real-time method, the first magnetic pole 111 is different from the second magnetic pole 410, and an attractive force is generated between the different magnetic poles. The attractive force between the first magnetic part 110 and the second magnetic part 400 drives the flip beam 100 to move, so that the flip beam 100 moves toward the second magnetic part 400.

[0054] When the turnover beam 100 is lifted, the magnetic poles of the upper half and the lower half of the first magnetic member 110 are different, and the magnetic poles of the upper half and the lower half of the second magnetic member 400 are different. As shown in Figure 3 the upper half of the first magnetic member 110 is N pole and the lower half is S pole, and the upper half of the second magnetic member 400 is S pole and the lower half is N pole. The first magnetic member 110 and the second magnetic member 400 drive the turnover beam 100 through repulsion.

[0055] The first magnetic member 110 and the second magnetic member 400 can be rectangular, and the structure of the first magnetic member 110 and the second magnetic member 400 is simple, and the finished product structure can be purchased, and the cost is not high. Of course, other shapes are also available, which can be selected as needed.

[0056] When the first magnetic member 110 is located at the upper end of the turnover beam 100, the first magnetic member 110 and the second magnetic member 400 are attracted to each other, driving the turnover beam 100 to rise and rotate to switch from the recovery position to the closed position. If the lower end of the turnover beam 100 is also provided with the first magnetic member 110 at this time, the first magnetic member 110 at the lower end and the corresponding second magnetic member 400 need to be repelled to drive the turnover beam 100 to rise.

[0057] When the first magnetic member 110 is located at the upper end of the turnover beam 100, the first magnetic member 110 and the second magnetic member 400 are repelled to each other, driving the turnover beam 100 to descend and rotate to switch from the recovery position to the closed position. If the lower end of the turnover beam 100 is also provided with the first magnetic member 110 at this time, the first magnetic member 110 at the lower end and the corresponding second magnetic member 400 need to be attracted to each other to drive the turnover beam 100 to descend.

[0058] It should be noted that whether the turnover beam 100 is lifted to switch positions or lowered to switch positions, the first magnetic member 110 can be provided at least one end of the turnover beam 100, and the two ends of the turnover beam 100 do not need to be provided with the first magnetic member.

[0059] It can be understood that the first magnetic member 110 is a permanent magnet or an electromagnet. Of course, the second magnetic member 400 can also be a permanent magnet or an electromagnet, which can be selected as needed.

[0060] The first magnetic member 110 and the second magnetic member 400 can be permanent magnets, which have a simple structure; or the first magnetic member 110 and the second magnetic member 400 can be electromagnets, and the magnetic properties and magnetic field strength can be adjusted as needed; or the first magnetic member 110 is a permanent magnet and the second magnetic member 400 is an electromagnet, or the first magnetic member 110 is an electromagnet and the second magnetic member 400 is a permanent magnet. The first magnetic member 110 and the second magnetic member 400 can be flexibly combined and suitable for various occasions, which can be selected as needed.

[0061] When one of the first magnetic member 110 and the second magnetic member 400 is an electromagnet, the electromagnet can be turned on and off according to the door opening signal and the door closing signal, or according to the position of the flip beam, and the specific selection can be made according to needs.

[0062] It can be understood that the first magnetic member 110 is located at at least one end of the flip beam 100. The first magnetic member 110 is located at the end of the flip beam 100, which can reduce the distance between the first magnetic member 110 and the second magnetic member 400, and reduce the requirements for the magnetic field force, so as to reduce the volume of the first magnetic member 110 and the second magnetic member 400, and the requirements for the installation space are not high, which is convenient for assembly.

[0063] refer to Figure 1 and Figure 2 As shown, the first magnetic member 110 is located at the lower end of the flip beam 100. Of course, the first magnetic member 110 can also be provided at the upper end of the flip beam 100, or the first magnetic member 110 can be provided at both the upper and lower ends of the flip beam 100, which can be selected according to needs.

[0064] The first magnetic member 110 is rigidly connected to the flip beam 100 to ensure that the magnetic field force between the first magnetic member 110 and the second magnetic member 400 remains stable, preventing it from being excessively large or insufficient. The first magnetic member 110 can be concealed within the flip beam 100, and the second magnetic member 400 can be concealed within the cabinet, resulting in a simpler appearance for the flip beam 100 and the inner container 300. Of course, the first magnetic member 110 can also be placed on the outside of the wall of the flip beam 100, depending on the needs.

[0065] When the door is closed, the flip beam 100 rotates and rises. When the door is opened, the pulling force of the door overcomes the magnetic field force and pulls the flip beam 100 out of the cabinet, releasing the magnetic field force and the cabinet from limiting the flip beam 100. Under the action of gravity, the flip beam 100 can move in the opposite direction along the guide direction of the first guide part and the second guide part, so that the flip beam 100 returns to the return position.

[0066] In some cases, a reset component is provided between the flip beam 100 and the door body. The reset component's restoring force allows the flip beam 100 to return to its restored position. During the door closing process, the flip beam 100 may also rotate and descend. During this movement, the flip beam 100 must overcome the resistance of the reset component, which accumulates a restoring force. During the door opening process, the pulling force of the door overcomes the magnetic field force, pulling the flip beam 100 out of the cabinet body, releasing the magnetic field force and the cabinet body from restraining the flip beam 100. The restoring force of the reset component drives the flip beam 100 back to its restored position and restrains the flip beam 100 in the restored position.

[0067] The reset component can be a torsion spring, with one end secured to the flip beam 100 and the other to the door body. This provides a simple structure and a good retaining effect. The reset component also stabilizes the flip beam 100 in the restored position, preventing wobbling that could affect the user experience. Alternatively, the reset component can be another structure that drives the flip beam 100 to return to the restored position, such as a spring. The specific selection can be based on actual needs.

[0068] It should be noted that, in the process of switching the flip beam 100 from the restoring position to the closed position, it is necessary to overcome the resistance of the stop structure.

[0069] Next, combine Figure 1 and Figures 4 to 6 As shown in FIG. 1 , the structure of the connecting portion 200 will be described.

[0070] It can be understood that one of the first guide part and the second guide part is set as a guide groove 210, and the other is set as a guide block arranged in the guide groove 210. The guide groove 210 extends along a curve around a preset axis. It can be understood that the guide groove 210 is a spiral groove, so that the flip beam 100 can move along a spiral path to achieve switching from the recovery position to the closed position.

[0071] That is, one of the connecting part 200 and the flip beam 100 is provided with a guide groove 210, and the other is provided with a guide block located in the guide groove 210. The structure is simple and convenient for disassembly and assembly, and the flip beam 100 cooperates with the connecting part 200 to realize position switching. The inner liner 300 of the cabinet does not need to be provided with a guide structure, which can simplify the structure of the inner liner 300, making the structure of the inner liner 300 more concise and beautiful, which helps to improve the user experience.

[0072] The guide groove 210 extends along a curve around a preset axis. It can be understood that the guide groove 210 is spiral. Correspondingly, the guide block can be set as a columnar block or a spiral block adapted to the guide groove 210, and the specific selection can be made according to needs. The preset axis can be parallel to or form an angle with the rotation axis of the flip beam 100, which can ensure that the flip beam 100 switches between the closed position and the return position. If the preset axis forms an angle with the rotation axis of the flip beam 100, the angle is as small as possible to avoid affecting the sealing effect of the flip beam 100 on the gap. The flip beam 100 is provided with a guide block, and the connecting portion 200 is provided with a guide groove 210. Of course, the guide block can also be provided at the connecting portion 200, and the guide groove 210 is provided at the flip beam 100.

[0073] The first angle of rotation of the flip beam 100 from the closed position to the restored position corresponds to a second angle corresponding to the orthographic projection of the guide groove 210 along the axial direction of the connecting portion 200. The first angle and the second angle are the same, so that the flip beam 100 is limited by the guide groove 210. When the flip beam 100 rotates 90° from the closed position to the restored position, the orthographic projection of the guide groove 210 along the axial direction of the moving component corresponds to a 90° center angle.

[0074] It should be noted that if Figure 4 and Figure 5 As shown, the guide groove 210 spirally extends from bottom to top and from right to left. At this time, the flip beam 100 makes an upward movement from bottom to top to achieve the switch from the return position to the closed position; when the flip beam 100 makes a downward movement from top to bottom to achieve the switch from the return position to the closed position, the spiral manner of the guide groove 210 needs to be opposite to the direction shown in the figure, that is, the guide groove 210 spirally extends from bottom to top and from left to right (not shown in the figure).

[0075] It can be understood that one of the connecting part 200 and the flip beam 100 is provided with a connecting shaft, and the other is provided with a connecting hole 240. The connecting shaft is rotatably connected to the connecting hole 240, and the flip beam 100 is rotatably connected to the door body through the connecting part 200. The connecting part 200 acts as a hinge. The function of the connecting part 200 is more diverse, and dedicated hinges can be reduced or not provided. The number of parts of the door assembly can also be reduced, which facilitates the disassembly and assembly of the flip beam 100 and the door body, thereby improving assembly efficiency.

[0076] It should be noted that the guide groove 210 or the guide block is provided on the hole wall of the connecting hole 240 , and the structure of the connecting portion 200 is simple.

[0077] It is understood that the door body is provided with a first clamping portion, the connecting portion 200 is provided with a second clamping portion 220, and the second clamping portion 220 is clamped to the first clamping portion. That is, the connecting portion 200 is clamped to the door body, and the structure is simple and convenient for assembly and disassembly.

[0078] The connecting portion 200 is further provided with an inserting portion 230, which is inserted into a corresponding inserting hole or inserting slot. Figure 5 and Figure 6 As shown, the connecting part 200 can be hung on the door body through the second clamping part 220, and then the plug-in part 230 is plugged into the door body. The connecting part 200 is limited by the cooperation between the plug-in part 230 and the second clamping part 220 to ensure the connection stability between the connecting part 200 and the door body and prevent the connecting part 200 from being separated from the door body.

[0079] In some cases, the connecting part 200 can also be provided with only the second clamping part 220 or only the plug-in part 230, and the second clamping part 220 is fixed to the door body, and the plug-in part 230 is fixed to the door body through interference fit, so that the structure of the connecting part 200 is simpler.

[0080] Of course, the connecting portion 200 can also be connected to the door body in other detachable ways, such as riveting; or, the connecting portion 200 can also be fixed to the door body as an integrated structure, such as welding.

[0081] refer to Figure 5 and Figure 6 As shown, the connecting portion 200 is an independent part, and the connecting portion 200 also includes a plate portion 250. A hole wall of a connecting hole 240 is provided on one side of the plate portion 250, and a guide groove 210 is opened on the hole wall. A second clamping portion 220 and a plug-in portion 230 are provided on the other side of the plate portion 250, and the structure is simple.

[0082] Combine Figures 1 to 7 As shown, Figure 1 and Figure 7 Both show that the flip beam 100 is in a closed position. Figures 1 to 3 The relative positions of the first magnetic member 110 and the second magnetic member 400 are shown. Figure 1 、 Figures 4 to 6 The structure of the connecting portion 200 is shown schematically.

[0083] When closing the door, the first magnetic member 110 and the second magnetic member 400 approach each other, and magnetic force is generated. The first magnetic member 110 and the second magnetic member 400 at the upper end of the flip beam 100 are attracted to each other, and / or the first magnetic member 110 and the second magnetic member 400 at the lower end of the flip beam 100 repel each other. Under the action of the magnetic force, the flip beam 100 is subjected to a vertical upward magnetic force, and the magnetic field force is used to drive the flip beam to rise. Due to the restriction of the guide groove 210 of the connecting part 200, the flip beam 100 rises and rotates at the same time, so that the flip beam switches from the recovery position to the closed position, realizing the flip function, switching and maintaining the closed position.

[0084] When the door is opened, the first magnetic member 110 and the second magnetic member 400 move away from each other, the magnetic force disappears, and the flip beam 100, under the action of its own weight, follows the guide path of the guide groove 210, and simultaneously descends and rotates to return to the return position. The above embodiment provides a method in which the flip beam 100 is driven by the magnetic field force to rise from the return position to the closed position, and returns to the return position from the closed position by its own gravity. However, the flip beam 100 can also be driven to descend by the magnetic field force to switch from the return position to the closed position. At this time, the first magnetic member 110 at the upper end of the flip beam 100 and the second magnetic member 400 repel each other, and / or the first magnetic member 110 at the lower end of the flip beam 100 and the second magnetic member 400 attract each other, and the magnetic field force is used to drive the flip beam 100 to descend; at this time, the flip beam 100 in the closed position is in a low position and cannot return to the return position by gravity. At this time, the flip beam 100 needs to be provided with a reset component, and the flip beam 100 is driven to switch from the closed position to the return position by the restoring force of the reset component.

[0085] Based on the above embodiment, the door assembly can generate and cancel the magnetic field force through the action of opening and closing the door, and use this force to drive the flip beam 100 to work. It has a simple structure and good stability, and the flip beam 100 will not get stuck.

[0086] When the flip beam 100 is switched from the return position to the closed position by ascending, when the flip beam 100 is in the closed position, that is, the door body is in the closed state, a gap is left between the lower end surface of the flip beam 100 and the bottom wall of the cabinet body, and this gap is greater than or equal to the distance the flip beam 100 is ascended, so as to ensure that the flip beam 100 in the return position can smoothly enter the cabinet body and avoid interference between the flip beam 100 and the cabinet body. When the flip beam 100 is switched from the return position to the closed position by descending, when the flip beam 100 is in the closed position, that is, the door body is in the closed state, a gap is left between the upper end surface of the flip beam 100 and the top wall of the cabinet body, and this gap is greater than or equal to the distance the flip beam 100 is descended, so as to ensure that the flip beam 100 in the return position can smoothly enter the cabinet body.

[0087] A second embodiment of the present invention provides a storage cabinet comprising a cabinet body and the door assembly described in the above embodiment, the door assembly being connected to the cabinet body. The cabinet body is provided with a second magnetic member 400. The second magnetic member 400 cooperates with the first magnetic member 110 to provide motional power to the tilt beam 100. The aforementioned advantages of the door assembly are also achieved by the storage cabinet. These advantages will not be further elaborated here; please refer to the above for details.

[0088] With reference to the above, the flip beam 100 is used for sealing a storage cabinet with a double-door, which includes a first door assembly connected to the cabinet body and a second door assembly connected to the cabinet body, wherein the first door assembly is the aforementioned door assembly.

[0089] Among them, the storage cabinet can be a variety of products such as refrigerators, freezers, display cabinets, cold storage cabinets or sales cabinets. The application range of the flip beam 100 component is wide, the structure is simple and the performance is stable.

[0090] It can be understood that a first magnetic member 110 is provided at both ends of the flip beam 100, wherein the first magnetic pole 111 of the first magnetic member 110 at one end and the second magnetic pole 410 of the corresponding second magnetic member 400 have different magnetic poles, and the first magnetic pole 111 of the first magnetic member 110 at the other end and the second magnetic pole 410 of the corresponding second magnetic member 400 have the same magnetic pole.

[0091] The second magnetic member 400 corresponding to the first magnetic member 110 can be understood as the two magnetic members being located on the same side of the locker, such as both being located on the upper side of the locker, or both being located on the lower side of the locker.

[0092] by Figure 3 For example, the first magnetic pole 111 of the first magnetic member 110 located at the lower end of the flip beam 100 is the same as the second magnetic pole 410 of the corresponding second magnetic member 400, and a repulsive force is generated between the first magnetic member 110 and the second magnetic member 400. This repulsive force is used to drive the flip beam 100 to move upward, and at the same time, the flip beam 100 rotates and rises around the spiral guide groove 210 to achieve the switching of the flip beam 100 from the recovery position to the closed position.

[0093] In some cases, a first magnetic member 110 is also provided at the upper end of the flip beam 100. In this case, the first magnetic pole 111 is opposite the second magnetic pole 410, generating an attractive force between the first magnetic member 110 and the second magnetic member 400. This attractive force is used to drive the flip beam 100 upward, while the flip beam 100 simultaneously rotates and rises around the spiral guide groove 210 to switch the flip beam 100 from the return position to the closed position. The combination of the upper suction force and the lower repulsive force creates a dual effect that drives the flip beam 100 to move, resulting in a simple structure and accurate switching of the flip beam 100 from the return position to the closed position.

[0094] When the flip beam 100 switches from the recovery position to the closed position by moving downward, it can be achieved by adjusting the first magnetic pole 111 and the second magnetic pole 410 , and the structure is simple.

[0095] It can be understood that the cabinet body includes a cabinet body and an inner liner 300 located inside the cabinet body. A second magnetic part 400 is arranged between the cabinet body and the inner liner 300. It can be understood that the second magnetic part 400 is arranged on the outside of the inner liner 300 and does not affect the internal space and structure of the inner liner 300. The second magnetic part 400 does not occupy the internal space of the inner liner 300 and can expand the storage space.

[0096] In some cases, the second magnetic member 400 is rigidly connected to the inner liner 300 to ensure that the magnetic field force between the first magnetic member 110 and the second magnetic member 400 remains stable.

[0097] The above embodiments are intended to illustrate the present invention only and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be encompassed by the scope of the claims of the present invention.
