Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, and in particular to a flip beam assembly, a refrigerator, and a refrigerator control method. Background Art

[0002] For double-door refrigerators on the market, most of the refrigerator compartment doors adopt a double-door design, and a flip beam is usually used to seal the left and right refrigerator doors of the refrigerator compartment. Generally, the flip beam is installed on one side of the refrigerator door, and the flipping of the flip beam is used to seal the left and right refrigerator doors in the closed state and the refrigerator body.

[0003] At present, the existing double-door refrigerators usually use a mechanical structure to realize the flipping control of the flip beam. Specifically, a guide tongue is provided on the top of the flip beam, and a guide seat with a guide groove is installed on the upper part of the refrigeration box body. When the refrigerator door is opened and closed, the flipping of the flip beam is realized by the contact and guidance between the guide tongue and the groove wall of the guide groove on the guide seat. However, when heavy objects such as bottles and beverages are placed on the refrigerator door body, and the refrigerator door body is affected by natural gravity and long-term use and impact, the hinge of the refrigerator sinks and deforms downward. The deformation of the refrigerator hinge causes the refrigerator door body to sink as a whole, and the flip beam sinks with the door body, resulting in the flip beam guide tongue and the guide groove not contacting, thereby causing the flip beam to fail and fail to flip, resulting in the refrigerator door body being unable to close normally, affecting the refrigeration effect; and when the user closes the two refrigerator doors of the refrigeration room, in order to prevent the flip beam from colliding with the other refrigerator door body due to position interference, the user can only close the refrigerator door body equipped with the flip beam first, and then close the other refrigerator door body, which will reduce the user's use experience. Summary of the invention

[0004] Based on this, it is necessary to provide a flip beam assembly that can be precisely controlled.

[0005] In order to solve the above technical problems, this application provides the following technical solutions:

[0006] A flip beam assembly, the flip beam assembly comprising:

[0007] A flip beam, which is used to be rotatably mounted on the refrigerator door, wherein a locking member is disposed inside the flip beam;

[0008] a flip beam hinge, used for fixedly mounting on the refrigerator door, the flip beam hinge being formed with a first crown gear, the first crown gear being disposed in the flip beam;

[0009] A driving assembly is installed in the flip beam, the driving assembly includes a motor and a driving gear, the driving gear is meshed with the first crown gear and is drivingly connected to the motor, the motor is connected to the flip beam in a circumferentially limited manner, and is used to control the forward and reverse rotation of the driving gear;

[0010] an anti-rotation pin, rotatably mounted in the flip beam and meshing with the driving gear;

[0011] Wherein, the anti-rotation pin has a first position and a second position. When the anti-rotation pin is in the first position, the anti-rotation pin abuts against the locking member to limit the flip beam to the refrigerator door in an open state; when the anti-rotation pin is in the second position, the anti-rotation pin abuts against the locking member to limit the flip beam to the refrigerator door in a closed state.

[0012] It can be understood that, by utilizing the action force and reaction force, when the motor controls the driving gear to rotate forward and reverse, the flipping drive of the flip beam on the refrigerator door can be realized, so that the flipping of the flip beam is not affected by the sinking of the refrigerator door, thus ensuring that the flip beam continues to be effective; in this process, the abutment limit between the anti-rotation pin and the locking member is utilized to realize the locking of the position of the flip beam when the refrigerator door is opened or closed. On the one hand, this can avoid the collision between the flip beam and the opposite refrigerator door, so that the closing operation of the refrigerator door equipped with the flip beam does not need to be in sequence, which has the effect of improving the user experience; on the other hand, it also simplifies the structure required for locking the flip beam, which has the effect of reducing costs.

[0013] In one embodiment, the locking member is disposed on the movement path of the anti-rotation pin, and a position interference portion is formed between the locking member and the anti-rotation pin;

[0014] The anti-rotation pin is configured to undergo elastic deformation in response to the pushing of the position interference portion, so that the anti-rotation pin switches back and forth between the first position and the second position.

[0015] It can be understood that by setting a position interference portion between the locking member and the anti-rotation pin, and adopting a design that allows elastic deformation of the anti-rotation pin, the anti-rotation pin can switch between the first position and the second position, thereby ensuring the stability and reliability of the anti-rotation pin's limiting action.

[0016] In one embodiment, a second crown gear is formed on one end of the anti-rotation pin, and the anti-rotation pin can be meshed with the driving gear through the second crown gear;

[0017] Wherein, a locking fitting is provided on the anti-rotation pin, and the anti-rotation pin can be abutted against the locking fitting to limit position.

[0018] In one embodiment, the locking member has a first arc surface and a second arc surface, and the first arc surface and the second arc surface are arranged on both sides of the locking member;

[0019] Wherein, the locking fitting has an arc convex surface, and when the anti-rotation pin is in the first position, the arc convex surface abuts against the first arc surface; when the anti-rotation pin is in the second position, the arc convex surface abuts against the second arc surface.

[0020] It can be understood that by providing the first arc surface and the second arc surface of the locking piece and the arc convex surface of the locking mating piece, when the locking mating piece moves, the arc convex surface cooperates with the first arc surface and the second arc surface of the locking piece, so that the transition is smoother when the locking piece moves, thereby making the anti-rotation pin more stable when switching between the first position and the second position.

[0021] In one embodiment, the locking fitting comprises a locking portion and a connecting portion, the locking portion extends along the axial direction of the anti-rotation pin, and the locking portion is connected to the anti-rotation pin through the connecting portion;

[0022] Wherein, the arc convex surface is arranged on the locking portion.

[0023] It can be understood that by providing a connecting part, the locking part is connected to the anti-rotation pin through the connecting part, so that the elastic deformation range of the locking part is larger, so that the arc convex surface can better withstand and transmit force when cooperating with the locking piece, and the locking part will not break due to excessive force.

[0024] This application also provides the following technical solutions:

[0025] A refrigerator, comprising a refrigerator door and a flip beam assembly as described in any one of the above embodiments;

[0026] The flip beam is rotatably mounted on the refrigerator door, and the flip beam hinge is fixedly mounted on the refrigerator door.

[0027] In one embodiment, the refrigerator further comprises a first detection sensor and a second detection sensor, wherein the first detection sensor is used to detect the state of the refrigerator door and generate a first feedback signal, and the first feedback signal is used to control the forward or reverse rotation of the motor;

[0028] The second detection sensor is used to detect the state of the flip beam and generate a second feedback signal, and the second feedback signal is used to control the motor to stop.

[0029] It can be understood that the setting of the first detection sensor and the second detection sensor realizes real-time monitoring of the status of the refrigerator door and the flip beam, and controls the forward and reverse rotation and shutdown of the motor according to the detection signal, so that the flipping action of the flip beam can be accurately coordinated with the status of the refrigerator door.

[0030] In one embodiment, the refrigerator further comprises a box body and an automatic door opening mechanism, wherein the automatic door opening mechanism is mounted on the box body and is used to push up the refrigerator door to open the refrigerator door;

[0031] Wherein, the refrigerator door is rotatably mounted on the box body.

[0032] This application also provides the following technical solutions:

[0033] A refrigerator control method, the refrigerator control method comprising the following steps:

[0034] S1: Acquire the state of a refrigerator door, wherein the refrigerator door is installed with a flip beam assembly as described in any one of the above embodiments;

[0035] S2: driving the flip beam to flip;

[0036] S3: Acquire the state of the flip beam;

[0037] S4: Control the flip beam to stop.

[0038] It can be understood that this refrigerator control method can monitor the status of the refrigerator door and the flip beam, and accurately control the refrigerator door and the flip beam, thereby realizing the automatic control of the refrigerator door opening and the flip beam flipping.

[0039] In one embodiment, the state of the refrigerator door includes an open state; when the state of the refrigerator door is the open state, the method further includes:

[0040] S5: After controlling the flip beam to stop, driving the refrigerator door to open.

[0041] Compared with the prior art, the flip beam assembly, refrigerator and refrigerator control method utilize the action force and reaction force to realize the flipping drive of the flip beam on the refrigerator door when the motor controls the driving gear to rotate forward and reverse, so that the flipping of the flip beam is not affected by the sinking of the refrigerator door, thereby ensuring that the flip beam continues to be effective; in this process, the abutment limit between the anti-rotation pin and the locking member is utilized to realize the locking of the position of the flip beam when the refrigerator door is opened or closed. On the one hand, this can avoid the collision between the flip beam and the opposite refrigerator door, so that the closing operation of the refrigerator door equipped with the flip beam does not need to be in sequence, which has the effect of improving the user experience; on the other hand, it also simplifies the structure required for locking the flip beam, which has the effect of reducing costs.

The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0061] See also Figures 1 to 10 The present application provides a flip beam assembly 100, which includes a flip beam 10, a flip beam hinge 20, a drive assembly 30 and an anti-rotation pin 40. The flip beam 10 is used to be rotatably mounted on a refrigerator door 210, and a locking member 11 is arranged in the flip beam 10; the flip beam hinge 20 is fixedly mounted on the refrigerator door 210, and the flip beam hinge 20 is formed with a first crown gear 21, and the first crown gear 21 is arranged in the flip beam 10; the drive assembly 30 is installed in the flip beam 10, and the drive assembly 30 includes a motor 31 and a drive gear 32, and the drive gear 32 is meshed with the first crown gear 21 and is connected to the motor The motor 31 is connected to the flip beam 10 in a circumferentially limited manner, and is used to control the forward and reverse rotation of the driving gear 32; the anti-rotation pin 40 is rotatably installed in the flip beam 10 and meshes with the driving gear 32; wherein the anti-rotation pin 40 has a first position and a second position, when the anti-rotation pin 40 is in the first position, the anti-rotation pin 40 abuts against the locking member 11 for limiting the flip beam 10 to be in the open state of the refrigerator door 210; when the anti-rotation pin 40 is in the second position, the anti-rotation pin 40 abuts against the locking member 11 for limiting the flip beam 10 to be in the closed state of the refrigerator door 210.

[0062] As can be seen from the above, by utilizing the action force and reaction force, when the motor 31 controls the driving gear 32 to rotate forward and reverse, the flipping drive of the flip beam 10 on the refrigerator door 210 can be realized, so that the flipping of the flip beam 10 is not affected by the sinking of the refrigerator door 210, which can ensure that the flip beam 10 continues to be effective; in this process, the abutment limit between the anti-rotation pin 40 and the locking member 11 is used to lock the position of the flip beam 10 when the refrigerator door 210 is in the open and closed state. On the one hand, this can avoid the collision between the flip beam 10 and the opposite refrigerator door 210, so that the closing operation of the refrigerator door 210 equipped with the flip beam 10 does not need to be in sequence, which has the effect of improving the user experience; on the other hand, it also simplifies the structure required for locking the flip beam 10, which has the effect of reducing costs.

[0063] like Figures 6 to 8 As shown, when the refrigerator door 210 is closed, the flip beam 10 is parallel to the left refrigerator door 210 , and when the refrigerator door 210 is closed, the flip beam 10 is perpendicular to the left refrigerator door 210 .

[0064] like Figure 2 As shown, the locking member 11 is arranged on the movement path of the anti-rotation pin 40, and a position interference portion 12 is formed between the locking member 11 and the anti-rotation pin 40; wherein the anti-rotation pin 40 is configured to undergo elastic deformation in response to the pushing of the position interference portion 12, so that the anti-rotation pin 40 switches back and forth between the first position and the second position. In this way, by providing the position interference portion 12 between the locking member 11 and the anti-rotation pin 40, and the anti-rotation pin 40 adopts a design that can undergo elastic deformation, the anti-rotation pin 40 can switch between the first position and the second position, thereby ensuring the stability and reliability of the anti-rotation pin 40 in the limiting action.

[0065] Here, the locking member 11 is made of the same material as the flip beam 10 , which may be plastic, metal or composite material.

[0066] In this embodiment, the locking member 11 and the flip beam are both made of plastic. The locking member 11 is fixed to the back cover of the flip beam and is integrally formed with the back cover of the flip beam 10 .

[0067] In one embodiment, if Figures 3 to 5 As shown, the locking member 11 has a first arc surface 111 and a second arc surface 112, which are arranged on both sides of the locking member 11. The anti-rotation pin 40 is provided with a locking fitting 41, and the anti-rotation pin 40 can be limited by abutting against the locking member 11 through the locking fitting 41. The locking fitting 41 has an arc convex surface 411, and when the anti-rotation pin 40 is in the first position, the arc convex surface 411 abuts against the first arc surface 111; when the anti-rotation pin 40 is in the second position, the arc convex surface 411 abuts against the second arc surface 112. By providing the first arc surface 111 and the second arc surface 112 of the locking member 11 and the arc convex surface 411 of the locking fitting 41, when the locking fitting 41 moves, the arc convex surface 411 cooperates with the first arc surface 111 and the second arc surface 112 of the locking member 11, so that the transition is smoother when the locking member 11 moves, thereby making the anti-rotation pin 40 more stable when switching between the first position and the second position.

[0068] In this embodiment, the locking member 11 is a rounded rectangle, and the first arc surface 111 and the second arc surface 112 are respectively two adjacent rounded side surfaces of the rounded rectangle.

[0069] like Figure 3 As shown, an arc-shaped groove 13 and a motor accommodating groove 14 are provided in the flip beam 10 , and the anti-rotation pin 40 is limited in the arc-shaped groove 13 . The diameter of the arc-shaped groove 13 is D1 , and the diameter of the anti-rotation pin 40 is D2 , D1>D2 , and the motor accommodating groove 14 is used to accommodate the motor 31 .

[0070] like Figure 2 and Figure 3As shown, the locking fitting 41 on the anti-rotation pin 40 includes a locking portion 412 and a connecting portion 413, wherein the locking portion 412 extends along the axial direction of the anti-rotation pin 40, and the locking portion 412 is connected to the anti-rotation pin 40 through the connecting portion 413; wherein the arc convex surface 411 is provided on the locking portion 412. By providing the connecting portion 413, the locking portion 412 is connected to the anti-rotation pin 40 through the connecting portion 413, so that the elastic deformation range of the locking portion 412 is larger, so that the arc convex surface 411 can better withstand and transmit force when cooperating with the locking member 11, and the locking portion 412 will not be broken due to excessive force.

[0071] In one embodiment, a second crown gear 42 is formed on one end of the anti-rotation pin 40 , and the anti-rotation pin 40 can mesh with the driving gear 32 through the second crown gear 42 .

[0072] like Figure 6 As shown, the present application also provides a refrigerator 200, including a refrigerator door 210 and a flip beam assembly 100 as in any one of the above embodiments; the flip beam 10 is rotatably mounted on the refrigerator door 210, and the flip beam hinge 20 is fixedly mounted on the refrigerator door 210.

[0073] In one embodiment, if Figure 6 and Figure 7 As shown, the refrigerator 200 further includes a first detection sensor 220 and a second detection sensor 230. The first detection sensor 220 is used to detect the state of the refrigerator door 210 and generate a first feedback signal, and the first feedback signal is used to control the forward or reverse rotation of the motor 31; the second detection sensor 230 is used to detect the state of the flip beam 10 and generate a second feedback signal, and the second feedback signal is used to control the motor 31 to stop. The first detection sensor 220 and the second detection sensor 230 are set to realize real-time monitoring of the states of the refrigerator door 210 and the flip beam 10, and control the forward, reverse rotation and shutdown of the motor 31 according to the detection signal, so that the flipping action of the flip beam 10 can be accurately matched with the state of the refrigerator door 210.

[0074] Here, the first detection sensor 220 and the second detection sensor 230 can be configured as a pressure sensor, a proximity sensor, etc., which can be selected as needed during use, and will not be described in detail here.

[0075] In one embodiment, the refrigerator 200 further includes a box body 240 and an automatic door opening mechanism 250, wherein the automatic door opening mechanism 250 is installed on the box body 240 and is used to push up the refrigerator door 210 to open the refrigerator door 210;

[0076] The refrigerator door 210 is rotatably mounted on the box body 240 .

[0077] In this embodiment, the automatic door opening mechanism 250 is configured as a push rod assembly. When the flip beam stops flipping, the push rod moves out to drive the refrigerator door 210 to open. Here, the automatic door opening mechanism 250 can also be configured as a magnetic structure, a spring structure, etc. Such automatic door opening mechanisms 250 are relatively common in the prior art and are not described in detail here.

[0078] like Fig. 9 and Fig.10 As shown, the present application also provides a refrigerator control method, which includes the following steps:

[0079] S1: Acquire the state of the refrigerator door 210, wherein the refrigerator door 210 is installed with a flip beam assembly 100 as in any of the above embodiments;

[0080] S2: driving the flip beam 10 to flip;

[0081] S3: Acquire the state of the flip beam 10;

[0082] S4: Control the flip beam 10 to stop.

[0083] This refrigerator control method can monitor the status of the refrigerator door 210 and the flip beam 10, and accurately control the refrigerator door 210 and the flip beam 10, thereby realizing automatic control of the opening of the refrigerator door 210 and the flipping of the flip beam 10.

[0084] The process of the motor 31 driving the flip beam 10 to rotate after receiving the sensor signal is as follows:

[0085] When the refrigerator door 210 is to be closed, after the first detection sensor 220 detects the first feedback signal (i.e., the refrigerator door 210 closing signal), the motor 31 is controlled to rotate forward, and the flip beam 10 starts to flip. The second detection sensor 230 detects the change of the flip beam 10, indicating that the flip beam 10 starts to flip. When the second detection sensor 230 detects that the flip beam 10 reaches the door closing state, a second feedback signal is issued to control the motor 31 to stop, and the flipping of the flip beam 10 stops.

[0086] When the refrigerator door 210 is to be opened, the user presses the left door. After the door status pressing switch detects the first feedback signal (i.e., the refrigerator door 210 opening signal), the motor 31 is started to reverse, and the flip beam 10 starts to flip. At this time, the second detection sensor 230 detects the change of the flip beam 10, indicating that the flip beam 10 starts to flip. When the second detection sensor 230 detects that the flip beam 10 reaches the door opening state, the motor 31 is controlled to stop, and the flipping of the flip beam 10 stops.

[0087] In one embodiment, the state of the refrigerator door 210 includes an open state; when the state of the refrigerator door 210 is the open state, the method further includes:

[0088] S5: After controlling the flip beam 10 to stop, driving the refrigerator door 210 to open.

[0089] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0090] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
