As shown in fig. 1 to 7, the present embodiment provides a vertical beam assembly 10 for a door body 20 of a refrigerator 1, the vertical beam assembly 10 including a vertical beam main body 100, a telescopic structure 200, a rotation shaft 300, and a coupling assembly 400. The vertical beam body 100 has a hollow portion 110 formed at an end in a longitudinal direction thereof. The telescopic structure 200 moves in the length direction of the vertical beam body 100 to extend from the hollow portion 110 or retract into the hollow portion 110.

The rotation shaft 300 is rotatably provided in a side of the vertical beam body 100 connected to the door body 20 of the refrigerator 1, and the rotation shaft 300 is configured to rotatably provide the vertical beam body 100 to the door body 20 of the refrigerator 1.

The linkage assembly 400 is disposed in the girder body 100, and is configured to cooperate with the rotation shaft 300 to move along the length direction of the girder body 100 when the rotation shaft 300 rotates, and to extend from the rotation shaft 300 to the middle of the telescopic structure 200 to extend or retract the telescopic structure 200 from or into the hollow portion 110.

In the present embodiment, the number of the door bodies 20 of the refrigerator 1 is not limited, and may be selected as needed. As a specific example, as shown in fig. 1 and 2, the refrigerator 1 is a three-door refrigerator 1.

In the present embodiment, the door body 20 of the refrigerator 1 rotatably coupled to the vertical beam assembly 10 is not limited and may be selected as desired. As a specific example, as shown in fig. 2 and 3, the vertical beam body 100 is connected to the left door body 20 of the refrigerator 1. It will be apparent that this is by way of example only and not by way of example only. In fig. 2, in order to fully illustrate the connection between the left door 20 and the vertical beam body 100 of the refrigerator 1, the right door 20 of the refrigerator 1 is not shown in fig. 2.

During the opening of the left door 20, the vertical beam body 100 is rotated out of the refrigerator 1 following the left door 20. During the closing of the left door 20, the vertical beam body 100 is screwed into the refrigerator 1 following the left door 20. In the case where the door body 20 of the refrigerator 1 is closed, as shown in fig. 1 and 2, the vertical beam body 100 is located between the left and right door bodies 20 and 20 to prevent cool air from leaking out from between the left and right door bodies 20 and 20.

In this embodiment, the end of the vertical beam body 100 in the length direction thereof may be an upper end of the vertical beam body 100 and/or a lower end of the vertical beam body 100. As a specific example, as shown in fig. 3, the end of the girder body 100 in the length direction thereof refers to the lower end of the girder body 100, and it is apparent that this is only exemplary and not exclusive.

In the present embodiment, the outer shape of the hollow portion 110 and the inner shape of the hollow portion 110 are not limited, and may be selected as needed. As a specific example, as shown in fig. 5 to 9, the outer shape of the hollow portion 110 and the inner shape of the hollow portion 110 are both arc-shaped, which facilitates screwing the vertical beam body 100 into the refrigerator 1 or unscrewing from the refrigerator 1. It will be apparent that this is by way of example only and not by way of example only.

In the present embodiment, the specific shape of the telescopic structure 200 is not limited, and may be selected as needed. As shown in fig. 7, as a specific embodiment, the telescopic structure 200 has a specific shape of an arc, and the outer peripheral wall of the telescopic structure 200 is attached to the inner wall of the hollow portion 110 and moves up and down along the inner wall of the hollow portion 110. The telescopic structure 200 with the shape has better choke effect.

In the present embodiment, the rotation shaft 300 is rotatably provided in one side of the vertical beam body 100. As shown in fig. 2 to 3, the left side of the vertical beam body 100 is rotatably provided on the left door body 20 of the refrigerator 1, and a rotation shaft 300 is rotatably provided in the left side of the vertical beam body 100. It will be apparent that this is by way of example only and not by way of example only. The rotation shaft 300 is provided at one side of the vertical beam body 100 such that the vertical beam assembly 10 is compact in structure and the left door 20 of the refrigerator 1 and the right door 20 of the refrigerator 1 can be opened independently.

During the opening of the door 20 of the refrigerator 1, the vertical beam body 100 is rotated about the rotation shaft 300 to be unscrewed from the refrigerator 1. During the closing of the door 20 of the refrigerator 1, the vertical beam body 100 is rotated about the rotation shaft 300 to be screwed into the refrigerator 1. In the present embodiment, the angle through which the vertical beam body 100 is rotated during the opening or closing of the door body 20 of the refrigerator 1 is not limited, and may be selected as desired.

In the present embodiment, the linkage assembly 400 is disposed in the vertical beam body 100, and the linkage assembly 400 is configured to be movable only in the longitudinal direction of the vertical beam body 100. That is, the interlock assembly 400 can move only in the longitudinal direction of the vertical beam body 100, i.e., the interlock assembly 400 can move only up and down.

In the present embodiment, the matching manner of the linkage assembly 400 and the rotation shaft 300 is not particularly limited. For example, when the interlocking unit 400 is engaged with the rotation shaft 300 by a concave-convex engagement or a pin groove engagement and the rotation shaft 300 rotates, the engagement can be performed to urge the interlocking unit 400 to move in the longitudinal direction of the vertical beam main body 100.

In the present embodiment, the specific manner of extending the linkage assembly 400 from the rotation shaft 300 to the middle of the telescopic structure 200 is not limited, and may be selected according to the need. The linkage assembly 400 extends to the middle of the telescopic structure 200 to make the telescopic structure 200 uniformly stressed, so that the telescopic structure 200 can be smoothly extended or retracted into the hollow portion 110 for a plurality of times.

The rotation shaft 300 is matched with the linkage assembly 400, so that the linkage assembly 400 moves along the length direction of the vertical beam main body 100 under the condition that the rotation shaft 300 rotates, and further drives the telescopic structure 200 to move. Accordingly, the vertical beam assembly 10 provided in this embodiment is closed with the door body 20 of the refrigerator 1, and the telescopic structure 200 thereof naturally extends to achieve the wind assembly effect. The vertical beam assembly 10 is naturally retracted with the opening of the door 20 of the refrigerator 1, and the telescopic structure 200 therein is opened to facilitate the opening of the door 20. The linkage assembly 400 extends to the middle of the telescopic structure 200 to make the telescopic structure 200 uniformly stressed, so that the telescopic structure 200 can be smoothly extended or retracted into the hollow portion 110 for a plurality of times.

In other embodiments, the linkage assembly 400 includes a linkage structure 430, and the linkage structure 430 moves along the length direction of the vertical beam main body 100 along with the linkage assembly 400, and is disposed in the hollow portion 110, and has a force application section 431.

The telescopic structure 200 has a receiving portion 210 protruding toward an end of the girder body 100, and a force applying section 431 is received in the receiving portion 210 to extend or retract the telescopic structure 200 from the hollow portion 110.

In the present embodiment, the specific shapes of the linkage structure 430 and the force application section 431 are not limited, and may be selected according to requirements. As shown in fig. 6, the linking structure 430 is L-shaped and the force applying section 431 is elongated. It will be apparent that this is by way of example only and not by way of example only.

As shown in fig. 7, the telescopic structure 200 has a receiving portion 210 protruding toward the end of the vertical beam body 100, that is, the telescopic structure 200 has an upwardly protruding receiving portion 210. The force applying section 431 is disposed in the accommodating portion 210 to extend or retract the telescopic structure 200 from the hollow portion 110. The connecting mode is simple and easy to detach and replace.

In other embodiments, the shape of the accommodating portion 210 and the force application section 431 is elongated, and the accommodating portion 210 and the force application section 431 are disposed along the transverse direction of the vertical beam main body 100. That is, the receiving portion 210 and the force application section 431 extend from one side of the vertical beam body 100 to the other side of the vertical beam body 100. That is, the receiving portion 210 and the urging section 431 extend from the left side of the vertical beam body 100 to the right side of the vertical beam body 100. This makes the telescopic structure 200 uniformly stressed.

In other embodiments, the force applying section 431 is configured to abut against the accommodating portion 210 to move the telescopic structure 200 when the telescopic structure 200 is retracted into the hollow portion 110. That is, as shown in fig. 9, the force applying section 431 abuts against the upper side of the accommodating portion 210 and drives the telescopic structure 200 to move upwards. That is, the force applying section 431 is the motive force for the upward movement of the telescopic structure 200.

In other embodiments, the mullion assembly 10 further comprises a plurality of second springs 500, the plurality of second springs 500 being disposed uniformly within the telescoping structure 200. A plurality of second springs 500 are used to connect the ends of the vertical beam body 100 and the telescopic structure 200, and are configured to be compressed when the telescopic structure 200 is retracted into the hollow 110.

As shown in fig. 10, the plurality of second springs 500 are configured to be compressed when the telescopic structure 200 is retracted into the hollow 110. As shown in fig. 9, when the telescopic structure 200 is extended out of the hollow 110, the compressed plurality of second springs 500 supply power to the telescopic structure 200 to extend the telescopic structure 200 out of the hollow 110. The plurality of second springs 500 are uniformly arranged so that the telescopic structure 200 is uniformly stressed, so that the telescopic structure 200 can be smoothly extended or retracted into the hollow portion 110 a plurality of times.

In other embodiments, the force applying section 431 is configured to disengage the interference receiving portion 210 when the telescoping structure 200 extends from within the hollow portion 110. As shown in fig. 9, the urging section 431 moves downward to disengage from the upper side of the interference receiving portion 210, and the telescopic structure 200 moves downward to protrude from the hollow portion 110 under the urging force of the second spring 500. That is, as shown in fig. 7, the distance between the upper side of the accommodating part 210 to the lower side of the accommodating part 210 defines the range in which the linkage assembly 400 and the telescopic structure 200 move up and down. This manner of controlling the movement of the telescoping structure 200 results in a uniform force on the telescoping structure 200.

In other embodiments, the linkage assembly 400 further includes a linkage shaft 410, where the linkage shaft 410 has a mating portion that mates with the rotation shaft 300. The coupling shaft 410 extends into the hollow portion 110 from the rotation shaft 300 through an end of the vertical beam body 100, and the coupling shaft 410 is configured to move in a length direction of the vertical beam body 100 when the rotation shaft 300 rotates. The linkage structure 430 has a conductive section 432, and both ends of the conductive section 432 are connected to the force applying section 431 and the linkage shaft 410, respectively.

In the present embodiment, the shape of the linkage shaft 410 is not limited, and for example, the linkage shaft 410 may be a circular shaft or a non-circular shaft. The specific shape of the fitting portion is not limited, and the shape of the fitting portion may be selected according to the concave-convex fitting or the shaft pin fitting.

In the present embodiment, the shape of the conductive segment 432 is not limited, and may be selected as needed. As a specific example, as shown in fig. 6, the conductive segments 432 are plate-shaped, and it is apparent that this is merely exemplary and not exclusive. The linkage assembly 400 is compact and easy to disassemble.

In other embodiments, the connecting shaft 410 extends out of two symmetrical clamping portions 413, and the conductive segment 432 is clamped between the two clamping portions 413. In the present embodiment, the specific shape of the engaging portion 413 is not limited, and may be selected as needed. As shown in fig. 19, the clamping portion 413 is a claw extending from the coupling shaft 410, and the conductive segment 432 is clamped between the two claws. And the middle portion of the conductive segment 432 is fixed to the coupling shaft 410 by a screw, which further prevents the coupling shaft 410 from rotating.

In other embodiments, the mullion assembly 10 for the door body 20 of the refrigerator 1 further includes a first spring 420. The first spring 420 is sleeved on the coupling shaft 410, and two ends of the first spring are respectively connected with the end portion of the vertical beam main body 100 and the matching portion, and configured to be compressed when the telescopic structure 200 extends out from the hollow portion 110.

The coupling shaft 410 is used for sleeving the first spring 420 thereon. The linkage shaft 410 is used for avoiding the problems of uneven stress or inclination of the first spring 420. In the present embodiment, the type of the coupling shaft 410 is not limited, and for example, the coupling shaft 410 may be a circular shaft or a non-circular shaft.

As shown in fig. 9, the first spring 420 is configured to be compressed when the telescopic structure 200 is extended from the hollow portion 110, that is, the first spring 420 is compressed to start the power storage when the coupling shaft 410 moves downward. As shown in fig. 10, when the telescopic structure 200 is retracted into the hollow portion 110, that is, when the coupling shaft 410 is moved upward, the coupling shaft 410 is moved toward the rotation shaft 300, the compressed first spring 420 provides upward power to the coupling shaft 410 to move the coupling shaft 410 upward.

As shown in fig. 3 to 13, when the rotation shaft 300 is engaged with the interlocking assembly 400 in a concave-convex manner, the end of the rotation shaft 300, which is close to the telescopic structure 200, has at least one protrusion. The interlock assembly 400 is configured to abut against different positions of the end of the rotation shaft 300 to move in the length direction of the girder body 100 in order to extend or retract the telescopic structure 200 from or into the hollow portion 110 in the case that the rotation shaft 300 rotates.

The end of the rotation shaft 300 near the telescopic structure 200 has at least one protrusion. That is, as a specific embodiment, as shown in fig. 5 to 11, the bottom end of the rotation shaft 300 has at least one protrusion. In the present embodiment, the shape, size, number, and the like of the projections are not particularly limited, and may be selected as needed.

During the rotation of the rotation shaft 300, the interlock assembly 400 collides with different positions of the end of the rotation shaft 300 to move in the length direction of the vertical beam body 100. That is, when the interlock assembly 400 collides against the protrusion, the protrusion presses the interlock assembly 400 to move the interlock assembly 400 downward along the length direction of the vertical beam body 100. Otherwise, the interlock assembly 400 moves upward along the length direction of the vertical beam body 100.

In the present embodiment, the specific structure of the end portion of the linkage assembly 400 abutting against the rotation shaft 300 is not limited, and may be selected according to the need. For example, the linkage assembly 400 has an abutting portion 411 adapted to the end of the rotating shaft 300, that is, the engaging portion is the abutting portion 411. As shown in fig. 5 to 9, when the door 20 of the refrigerator 1 is in the closed state, at least one protrusion abuts against the protrusion 4111 of the abutting portion 411, and at this time, the linkage assembly 400 and the telescopic structure 200 move downward to protrude from the hollow portion 110, so as to achieve the choke effect.

As shown in fig. 10, when the door 20 of the refrigerator 1 is in an opened state, at least one protrusion abuts against the recess 4112 of the abutting portion 411 to move the linkage assembly 400 and the telescopic structure 200 upward, and the telescopic structure 200 is retracted into the hollow portion 110. This can reduce the friction of the telescopic structure 200 so that the vertical beam body 100 is unscrewed from the refrigerator 1.

That is, when the door 20 of the refrigerator 1 is in the closed state, the protrusion collides with the protrusion 4111 of the collision portion 411, and at this time, the linkage assembly 400 moves downward, and the telescopic structure 200 also moves downward, so as to achieve the choke effect. When the door body 20 of the refrigerator 1 is in the open state, the protrusion collides with the recess 4112 of the collision portion 411, and at this time, the linkage assembly 400 moves upward, the telescopic structure 200 also moves upward, and the telescopic structure 200 retracts into the hollow portion 110, so that the vertical beam main body 100 can conveniently follow the door body 20 of the refrigerator 1 to rotate out of the refrigerator 1. The vertical beam assembly 10 provided in this embodiment is closed along with the door body 20 of the refrigerator 1, and the telescopic structure 200 therein naturally extends to achieve the wind assembly effect. The vertical beam assembly 10 is naturally retracted with the opening of the door 20 of the refrigerator 1, and the telescopic structure 200 therein is opened to facilitate the opening of the door 20.

In this embodiment, the angle through which the vertical beam main body 100 rotates in the process of opening the door body 20 of the refrigerator 1 to closing or in the process of closing the door body 20 of the refrigerator 1 to opening is not limited, and may be selected according to requirements. As a specific example, as shown in fig. 7 and 8, the vertical beam body 100 is rotated 90 ° counterclockwise during the closing to opening of the door body 20 of the refrigerator 1. The vertical beam body 100 is rotated by 90 ° clockwise during the process of opening to closing the door body 20 of the refrigerator 1.

In this embodiment, the specific components included in the linking component 400 are not limited, and may be selected according to requirements. As a specific embodiment, as shown in fig. 6, the linkage assembly 400 includes a linkage shaft 410 and a linkage structure 430. In the present embodiment, the specific manner of the linkage assembly 400 for extending or retracting the telescopic structure 200 from or into the hollow portion 110 is not limited. For example, the linkage assembly 400 may directly drive the telescopic structure 200 to move up and down, or the linkage assembly 400 indirectly drives the telescopic structure 200 to move up and down.

The end of the rotating shaft 300 in the vertical beam assembly 10 provided in this embodiment has at least one protrusion, and the rotating shaft 300 can trigger the linkage assembly 400 to move along the length direction of the vertical beam main body 100 during the rotation process, and the linkage assembly 400 enables the telescopic structure 200 to extend from the hollow portion 110 or retract into the hollow portion 110. This allows the vertical beam assembly 10 to naturally extend out of the telescopic structure 200 as the door 20 of the refrigerator 1 is closed to achieve a wind-up effect. The vertical beam assembly 10 is naturally retracted with the opening of the door 20 of the refrigerator 1, and the telescopic structure 200 therein is opened to facilitate the opening of the door 20.

Meanwhile, the abutting portion 411 can prevent the rotation shaft 300 from rotating at will, that is, the abutting portion 411 restricts the rotation of the rotation shaft 300. In the case where the door body 20 of the refrigerator 1 is opened, the vertical beam body 100 loses restriction, that is, the vertical beam body 100 may be rotated by a false touch, which makes it difficult to close the door body 20. The abutting portion 411 can prevent the vertical beam main body 100 from rotating at will to ensure smooth closing of the door body 20 of the refrigerator 1.

In other embodiments, the at least one protrusion includes a first protrusion 310 and a second protrusion 320. The first protrusion 310 is provided at an end surface of the rotation shaft 300. The second protrusions 320 are disposed at end surfaces of the rotation shaft 300 at equal intervals from the first protrusions 310 in the circumferential direction of the rotation shaft 300. Since the abutting portion 411 is fitted to the end portion of the rotation shaft 300, the abutting portion 411 has two projections 4111 provided at equal intervals in the circumferential direction thereof. As shown in fig. 5, the first protrusion 310 and the second protrusion 320 respectively collide with two protrusions 4111 of the collision portion 411, which makes the stress of the linkage assembly 400 and the telescopic structure 200 relatively balanced.

In other embodiments, the vertical beam body 100 is rotated through an angle ranging from 80 ° to 110 ° during the completion of opening or closing of the door body 20 of the refrigerator 1. That is, during the opening and closing of the door body 20 of the refrigerator 1, the vertical beam body 100 rotates 80 ° to 110 ° with the door body 20 to be rotated out of the refrigerator 1 or screwed into the refrigerator 1. That is, as shown in fig. 9 and 10, in the process of switching the two interference states of the rotation shaft 300 and the link assembly 400, the vertical beam body 100 is rotated through an angle range of 80 ° to 110 °, and in this process, the refrigerator 1 door 20 is switched to open and close.

As shown in fig. 1 and 2, if the rotation angle of the vertical beam body 100 is too small, the vertical beam body 100 is interfered by the structure of the right door body 20. That is, the left door body 20 cannot be opened alone, and the left door body 20 needs to be opened after the right door body 20 is opened. If the rotation angle of the vertical beam body 100 is too large, the vertical beam body 100 is not easily introduced into the refrigerator 1 when the door body 20 of the refrigerator 1 is changed from the opened state to the closed state. As a specific example, the vertical beam body 100 is rotated by 90 ° during the opening and closing of the door body 20 of the refrigerator 1.

In other embodiments, the peripheral wall of the abutting portion 411 has at least one limiting portion 412, and the at least one limiting portion 412 is matched with the vertical beam main body 100 to prevent the abutting portion 411 from rotating.

In the present embodiment, the shape of the limiting portion 412 is not limited, and the limiting portion 412 can prevent the abutting portion 411 from rotating, and the limiting portion 412 can move along the length direction of the vertical beam main body 100. As a specific example, as shown in fig. 6, the shape of the limiting portion 412 is an elongated shape, and it is obvious that this is only exemplary and not exclusive.

In the present embodiment, the number of the limiting portions 412 is not limited, and may be selected as needed. As a specific example, as shown in fig. 6, the number of the stopper portions 412 is 4, and is uniformly distributed along the outer peripheral wall of the interference portion 411.

In other embodiments, each of the protrusions has a first inclined portion 311, a connecting portion 312, and a second inclined portion 313 in order along the circumferential direction of the rotation shaft 300. The recess 4112 of the abutting portion 411 corresponds to a central angle 10 ° to 20 ° more than the central angle corresponding to the connecting portion 312. The second inclined portion 313 has a larger inclination than the first inclined portion 311.

In the present embodiment, the shapes of the first inclined portion 311, the connecting portion 312, and the second inclined portion 313 are not limited. As a specific example, as shown in fig. 11 and 12, the first inclined portion 311 and the second inclined portion 313 are inclined surfaces, and the connecting portion 312 is a horizontal surface.

The recess 4112 of the abutting portion 411 corresponds to a central angle 10 ° to 20 ° more than the central angle corresponding to the connecting portion 312. Therefore, as shown in fig. 12 and 13, when the protrusion is located in the recess 4112 of the abutting portion 411, the first inclined portion 311 has a flash seam with the protrusion 4111 of the abutting portion 411. That is, in the process of rotating the rotating shaft 300 from fig. 12 to fig. 13, the protrusion is always located in the recess 4112 of the abutting portion 411 in the process of rotating the rotating shaft 300 by 10 ° to 20 °. That is, the interlock assembly 400 does not move along the length direction of the girder body 100 during this process. That is, during the closing of the door body 20 of the refrigerator 1, the telescopic structure 200 does not protrude from the inside of the hollow portion 110 for the first 10 ° to 20 ° of the rotation of the vertical beam body 100. Optionally, the recess 4112 of the abutting portion 411 corresponds to a central angle of 65 ° and the connecting portion 312 corresponds to a central angle of 50 °, and the recess 4112 of the abutting portion 411 corresponds to a central angle 15 ° greater than the central angle of the connecting portion 312. This reduces friction between the telescopic structure 200 and the refrigerator 1, facilitating the rotation of the vertical beam body 100 into the refrigerator 1.

The second inclined portion 313 has a larger inclination than the first inclined portion 311. That is, the central angle corresponding to the second inclined portion 313 is smaller than the central angle corresponding to the first inclined portion 311. As shown in fig. 12 and 13, this facilitates the rotation of the rotation shaft 300 along the first inclined portion 311 to switch between two interference situations. The second inclined portion 313 has a large inclination, and the second inclined portion 313 serves to prevent the rotation shaft 300 from rotating at will.

In the present embodiment, the range of specific central angles corresponding to the first inclined portion 311 and the second inclined portion 313 is not limited, and may be selected as needed. As a specific example, as shown in fig. 12 and 13, the first inclined portion 311 corresponds to a center angle of 20 ° and the second inclined portion 313 corresponds to a center angle of 5 °.

In other embodiments, the central angle corresponding to the convex portion 4111 of the abutting portion 411 is greater than the central angle corresponding to the convex portion. Specific values of the central angle corresponding to the convex portion 4111 of the abutting portion 411 and the central angle corresponding to the convex portion are not limited, and the difference therebetween is not particularly limited. As shown in fig. 12, the central angle corresponding to the convex portion 4111 of the abutting portion 411 is 115 °, and the central angle corresponding to the protrusion is 75 °. The central angle corresponding to the convex portion 4111 of the abutting portion 411 is larger than the central angle corresponding to the protrusion, so that the protrusion can stably abut against the convex portion 4111 of the abutting portion 411.

As shown in fig. 14 to 20, when the rotation shaft 300 is engaged with the linkage assembly 400 by a pin, as a specific embodiment, the outer peripheral wall of the rotation shaft 300 has at least one limiting pin 330, that is, the engaging portion is the limiting pin 330. The linkage assembly 400 has a bearing portion 414, the bearing portion 414 is arc-shaped, and the bearing portion 414 is sleeved outside the outer peripheral wall of the rotating shaft 300. The carrier portion 414 has at least one guide portion 415 extending in the circumferential and axial directions of the carrier portion 414. The at least one guide portion 415 is configured to have at least one stopper pin 330 disposed therein in a one-to-one correspondence, and is configured to move the interlock assembly 400 along the longitudinal direction of the vertical beam body 100 when the rotation shaft 300 rotates.

As a specific example, as shown in fig. 20, the outer circumferential wall of the rotation shaft 300 has at least one stopper pin 330, and the outer circumferential wall of the rotation shaft 300 has two stopper pins 330. It should be apparent that this is by way of example only and not by way of limitation, and that the number of stop pins 330 may be one, three, four or more. In this embodiment, the limiting pin 330 and the rotation shaft 300 may be integrally formed or be a split structure. The shape of the stopper pin 330 is not particularly limited and may be selected as needed.

The interlock assembly 400 is disposed in the vertical beam body 100, and the interlock assembly 400 is configured to be movable only in the longitudinal direction of the vertical beam body 100. That is, the interlock assembly 400 can move only in the longitudinal direction of the vertical beam body 100, i.e., the interlock assembly 400 can move only up and down.

In this embodiment, the specific components included in the linking component 400 are not limited, and may be selected according to requirements. As a specific embodiment, as shown in fig. 18, the linkage assembly 400 includes a linkage shaft 410 and a linkage structure 430. In the present embodiment, the specific manner of the linkage assembly 400 for extending or retracting the telescopic structure 200 from or into the hollow portion 110 is not limited. For example, the linkage assembly 400 may directly drive the telescopic structure 200 to move up and down, or the linkage assembly 400 indirectly drives the telescopic structure 200 to move up and down.

In this embodiment, the linkage assembly 400 has a bearing portion 414, and the bearing portion 414 is arc-shaped. In the present embodiment, the specific shape of the bearing portion 414 is not limited, and for example, the bearing portion 414 may include a circular arc, may include a semi-cylinder shape, or include a cylinder. As a specific example, as shown in fig. 18, the carrier 414 comprises a cylinder, it being apparent that this is by way of example only and not by way of limitation.

In the present embodiment, the interval between the inner peripheral wall of the bearing and the outer peripheral wall of the rotation shaft 300 is not limited, and may be selected as needed. As shown in fig. 17, the space between the inner peripheral wall of the bearing and the outer peripheral wall of the rotating shaft 300 is small and negligible.

In the present embodiment, the specific number of the guide portions 415 is not limited, and may be selected as needed. As a specific example, as shown in fig. 19, the number of the guide portions 415 is two. It will be apparent that this is by way of example only and not by way of limitation, and that the number of guides 415 may be one, three, four or more, for example.

In this embodiment, the guide portion 415 and the carrying portion 414 may be integrally formed or be a split structure. For example, the guide portion 415 may be a blind groove or a through groove formed on the carrying portion 414.

In the present embodiment, the specific shape of the guide portion 415 is not limited, and as shown in fig. 19, the guide portion 415 may extend along the circumferential direction and the axial direction of the bearing portion 414. As shown in fig. 19, each guide portion 415 includes a first segment 4151, a middle segment 4152, and a second segment 4153 connected in order along the extending direction thereof, the first segment 4151 and the second segment 4153 being horizontal segments, the middle segment 4152 being disposed obliquely, wherein the first segment 4151 is adjacent to the telescopic structure 200. It will be apparent that this is by way of example only and not by way of example only.

During the rotation of the rotation shaft 300, since the interlocking assembly 400 cannot rotate, the interlocking assembly 400 moves in the longitudinal direction of the vertical beam body 100 with the cooperation of the stopper pin 330 and the guide portion 415.

Specifically, the stopper pin 330 moves from the first section 4151 to the second section 4153 during the closing of the door 20 of the refrigerator 1. The linkage assembly 400 moves toward the telescopic structure 200, i.e., downward. The telescopic structure 200 moves downward to protrude from the inside of the hollow portion 110 to achieve a choke effect.

During the opening of the door 20 of the refrigerator 1, the stopper pin 330 moves from the second section 4153 to the first section 4151. The linkage assembly 400 moves away from the telescopic structure 200, i.e., moves upward, and the telescopic structure 200 is retracted into the hollow portion 110. This can reduce the friction of the telescopic structure 200 so that the vertical beam body 100 is unscrewed from the refrigerator 1.

The vertical beam assembly 10 provided in this embodiment is closed along with the door body 20 of the refrigerator 1, and the telescopic structure 200 therein naturally extends to achieve the wind assembly effect. The vertical beam assembly 10 is naturally retracted with the opening of the door 20 of the refrigerator 1, and the telescopic structure 200 therein is opened to facilitate the opening of the door 20.

In the vertical beam assembly 10 provided in this embodiment, the rotation shaft 300 is matched with the pin slot of the linkage assembly 400, and in the process of closing the door body 20, the rotation of the rotation shaft 300 can trigger the linkage assembly 400 to move along the length direction of the vertical beam main body 100, and the linkage assembly 400 enables the telescopic structure 200 to extend from the hollow portion 110 or retract into the hollow portion 110. This allows the vertical beam assembly 10 to naturally extend out of the telescopic structure 200 as the door 20 of the refrigerator 1 is closed to achieve a wind-up effect. The vertical beam assembly 10 is naturally retracted with the opening of the door 20 of the refrigerator 1, and the telescopic structure 200 therein is opened to facilitate the opening of the door 20.

In other embodiments, each guide 415 is a groove formed in the peripheral wall of the carrier 414. This allows for a simple construction of the mullion assembly 10.

In other embodiments, the central angle corresponding to each guide 415 ranges from 80 ° to 100 °. That is, the vertical beam body 100 is rotated through an angle ranging from 80 ° to 110 ° in the process of completing the opening or closing of the door body 20 of the refrigerator 1. That is, during the opening and closing of the door body 20 of the refrigerator 1, the vertical beam body 100 rotates 80 ° to 110 ° with the door body 20 to be rotated out of the refrigerator 1 or screwed into the refrigerator 1. That is, the stopper pin 330 is moved from the second section 4153 to the first section 4151 or from the first section 4151 to the second section 4153, and the vertical beam body 100 is rotated through an angle ranging from 80 ° to 110 °, during which the door body 20 of the refrigerator 1 is completely switched to be opened and closed.

As shown in fig. 1 and 2, if the rotation angle of the vertical beam body 100 is too small, the vertical beam body 100 is interfered by the structure of the right door body 20. That is, the left door body 20 cannot be opened alone, and the left door body 20 needs to be opened after the right door body 20 is opened. If the rotation angle of the vertical beam body 100 is too large, the vertical beam body 100 is not easily introduced into the refrigerator 1 when the door body 20 of the refrigerator 1 is changed from the opened state to the closed state. As a specific example, as shown in fig. 24 to 26, the refrigerator 1 door 20 is rotated by 90 ° during opening and closing of the vertical beam body 100.

In other embodiments, each guide 415 includes a first segment 4151, a middle segment 4152, and a second segment 4153 that are sequentially connected along the extending direction thereof, the first segment 4151 is adjacent to the telescopic structure 200, the first segment 4151 is a horizontal segment, and the middle segment 4152 is disposed obliquely.

The stopper pin 330 moves from the first section 4151 to the second section 4153 during the closing of the door 20 of the refrigerator 1. The first section 4151 is a horizontal section, that is, the position of the linkage assembly 400 and the telescopic structure 200 is not changed during the movement of the first section 4151 by the limiting pin 330. That is, the interlock assembly 400 does not move along the length direction of the girder body 100 during this process. That is, the telescopic structure 200 does not protrude from the hollow portion 110 during the early rotation of the vertical beam body 100 during the closing of the door body 20 of the refrigerator 1. This reduces friction between the telescopic structure 200 and the refrigerator 1, facilitating the rotation of the vertical beam body 100 into the refrigerator 1.

During the opening of the door 20 of the refrigerator 1, the stopper pin 330 moves from the second section 4153 to the first section 4151. In the case where the door body 20 of the refrigerator 1 is opened, the vertical beam body 100 loses restriction, that is, the vertical beam body 100 may be rotated by a false touch, which makes it difficult to close the door body 20. The first section 4151 is located at the lower end, and the first section 4151 is a horizontal section, and the middle section 4152 is an inclined section, which can prevent the vertical beam main body 100 from being rotated randomly, so as to ensure smooth closing of the door body 20 of the refrigerator 1.

In other embodiments, the first segment 4151 is proximate the telescoping structure 200, and the first segment 4151 corresponds to a central angle in the range of 10 ° to 20 °. The limiting pin 330 is always positioned at the first section 4151 during the process of closing the door body 20 of the refrigerator 1 and the process of rotating the rotating shaft 300 by 10 ° to 20 °. That is, the interlock assembly 400 does not move along the length direction of the girder body 100 during this process. That is, during the closing of the door body 20 of the refrigerator 1, the telescopic structure 200 does not protrude from the inside of the hollow portion 110 for the first 10 ° to 20 ° of the rotation of the vertical beam body 100. This reduces friction between the telescopic structure 200 and the refrigerator 1, facilitating the rotation of the vertical beam body 100 into the refrigerator 1.

In other embodiments, as shown in fig. 18, the bearing portion 414 is cylindrical and is sleeved on the rotating shaft 300. The at least one guide portion 415 includes a first guide portion 415 and a second guide portion 415 disposed opposite to each other. The at least one stopper pin 330 includes a first stopper pin 330 and a second stopper pin 330 disposed along a radial direction of the rotation shaft 300, the first stopper pin 330 and the second stopper pin 330 being disposed in the first guide portion 415 and the second guide portion 415, respectively. This allows the force applied by the linkage assembly 400 and the telescoping structure 200 to be relatively balanced.

In other embodiments, the linkage assembly 400 further includes a linkage shaft 410 and a first spring 420. The coupling shaft 410 is disposed in the vertical beam body 100, has a bearing portion 414, and extends from the rotation shaft 300 through an end portion of the vertical beam body 100 into the hollow portion 110. The first spring 420 is sleeved on the coupling shaft 410, and two ends of the first spring are respectively connected with the end portion of the vertical beam main body 100 and the bearing portion 414, and configured to be compressed when the telescopic structure 200 extends out from the hollow portion 110.

In this embodiment, the linkage assembly 400 includes a linkage shaft 410, and the linkage shaft 410 is used to sleeve the first spring 420 thereon. The linkage shaft 410 is used for avoiding the problems of uneven stress or inclination of the first spring 420. In the present embodiment, the type of the coupling shaft 410 is not limited, and for example, the coupling shaft 410 may be a circular shaft or a non-circular shaft.

The first spring 420 is configured to be compressed when the telescopic structure 200 is extended from the hollow 110, that is, the first spring 420 is compressed to start the power storage when the coupling shaft 410 moves downward. When the telescopic structure 200 is retracted into the hollow portion 110, that is, when the coupling shaft 410 moves upward, the coupling shaft 410 moves toward the rotation shaft 300, the compressed first spring 420 provides upward power to the coupling shaft 410 to move the coupling shaft 410 upward.

In other embodiments, the mullion assembly 10 for the door body 20 of the refrigerator 1 further includes a plurality of second springs 500. The plurality of second springs 500 are uniformly disposed in the telescopic structure 200 for connecting the end of the vertical beam body 100 and the telescopic structure 200, and configured to be compressed when the telescopic structure 200 is retracted into the hollow 110.

The plurality of second springs 500 are configured to be compressed when the telescopic structure 200 is retracted into the hollow 110. When the telescopic structure 200 is extended out of the hollow 110, the compressed plurality of second springs 500 provide power to the telescopic structure 200 to extend the telescopic structure 200 out of the hollow 110. The plurality of second springs 500 are uniformly arranged so that the telescopic structure 200 is uniformly stressed, so that the telescopic structure 200 can be smoothly extended or retracted into the hollow portion 110 a plurality of times.

In other embodiments, the outer peripheral wall of the bearing portion 414 has at least one limiting portion 412, and the at least one limiting portion 412 cooperates with the mullion body 100 to prevent the bearing portion 414 from rotating.

In the present embodiment, the shape of the limiting portion 412 is not limited, and the limiting portion 412 can prevent the abutting portion 411 from rotating, and the limiting portion 412 can move along the length direction of the vertical beam main body 100. As a specific example, as shown in fig. 18, the shape of the limiting portion 412 is an elongated shape, and it is obvious that this is only exemplary and not exclusive.

In the present embodiment, the number of the limiting portions 412 is not limited, and may be selected as needed. As a specific example, as shown in fig. 18, the number of the stopper portions 412 is 4, and is uniformly distributed along the outer peripheral wall of the interference portion 411.

In other embodiments, the ends of the vertical beam body 100 along its length form an arcuate connecting structure 120. The vertical beam assembly 10 further includes a first fixing base 600, and the first fixing base 600 is disposed at the opening 30 of the refrigerator. The first fixing base 600 has a first guide groove 610 having an arc shape and opening forward. The first fixing base 600 is used for guiding the connection structure 120 into the first guide groove 610 along the inner sidewall of the first guide groove 610 or separating from the first guide groove 610 during the opening and closing of the door 20 of the refrigerator 1.

In the present embodiment, the opposite ends of the vertical beam body 100 and the hollow portion 110 form an arc-shaped connection structure 120, that is, the two ends of the vertical beam body 100 along the length direction thereof form the connection structure 120 and the hollow portion 110, respectively. As a specific example, as shown in fig. 3, the hollow portion 110 is located at the lower end of the girder body 100, and the connection structure 120 is located at the upper end of the girder body 100.

In the present embodiment, the range of the central angle corresponding to the circular arc-shaped connection structure 120 is not limited, and may be selected according to the need. As a specific example, as shown in fig. 4, the circular arc-shaped connection structure 120 corresponds to a central angle of 90 °.

As shown in fig. 4, the first fixing base 600 is used to fix the vertical beam body 100, and the first fixing base 600 is also used to prevent cool air from leaking out of the refrigerator 1. Since both the first guide groove 610 and the connection structure 120 are arc-shaped, as shown in fig. 8, a gap between the first guide groove 610 and the connection structure 120 is small and relatively uniform, which further prevents cool air from leaking out of the refrigerator 1.

In other embodiments, the inner sidewall of the first guide groove 610 includes a lead-in section 611 and a tangential section 612, and the lead-in section 611 and the tangential section 612 are sequentially connected along the lead-in direction of the connection structure 120 into the first guide groove 610. That is, as shown in fig. 21, 24, 25 and 26, the lead-in section 611 and the tangential section 612 are connected in order. The curvature of the lead-in section 611 is smaller than the curvature of the tangential section 612, i.e. the tangential section 612 is curved to a greater extent than the lead-in section 611. This facilitates the introduction of the connection structure 120 into the first fixing base 600, and also further reduces the gap between the first guide groove 610 and the connection structure 120, preventing the cool air from leaking out of the refrigerator 1.

In other embodiments, the lead-in segment 611 corresponds to a central angle in the range of 10 ° to 20 °. As a specific example, as shown in fig. 24, 25 and 26, the angle of the central angle corresponding to the lead-in section 611 is 15 °. This makes it easier for the connection structure 120 to be at the initial stage of the introduction of the first fixing base 600. That is, the telescopic structure 200 is also located in the hollow 110 at this stage, and the curvature of the introduction section 611 is smaller than that of the tangential section 612, so that the connection structure 120 is easily introduced into the first fixing base 600.

In other embodiments, the first fixing base 600 further includes a guide block 620, and the guide block 620 is disposed in the first guide groove 610. An end of the connecting structure 120 is provided with a strip-shaped guide groove 121; the guide groove 121 has an opening facing away from the rotation shaft 300 so that the guide block 620 is introduced into the guide groove 121 or is separated from the guide groove 121 during the opening and closing of the door 20 of the refrigerator 1.

In this embodiment, the specific shape of the guide block 620 may be selected according to need, and as a specific embodiment, as shown in fig. 21, 24, 25 and 26, the guide block 620 has a circular arc shape, which facilitates the guide block 620 to be guided into the guide groove 121.

The guide groove 121 has an opening facing away from the rotation shaft 300, that is, the opening 1211 of the guide groove and the rotation shaft 300 are located at both sides of the girder body 100, respectively. As shown in fig. 4, the rotation shaft 300 is located at the left side of the vertical beam body 100, and the opening 1211 of the guide groove is located at the right side of the vertical beam body 100. As shown in fig. 24, 25 and 26, the rotation shaft 300 is located at the right side of the vertical beam body 100, and the opening of the guide groove is located at the left side of the vertical beam body 100. Fig. 24, 25 and 26 illustrate a process in which the connection structure 120 is introduced into the first guide groove 610 along the inner sidewall of the first guide groove 610 or is separated from the first guide groove 610, and also illustrate a process in which the guide block 620 is introduced into the guide groove 121 or is separated from the guide groove 121. As shown in fig. 24, 25 and 26, the guide block 620 makes it easier to guide the connection structure 120 into the first fixing base 600, so as to avoid the connection structure 120 from deviating from the track.

In other embodiments, as shown in fig. 21, 24, 25 and 26, the guide block 620 is located at the end of the lead-in section 611 in the lead-in direction. That is, when the vertical beam body 100 rotates 10 ° to 20 °, the guide block 620 just contacts the opening 1211 of the guide groove, which facilitates smooth introduction of the connection structure 120 into the first fixing base 600.

In other embodiments, the guide block 620 and the guide groove 121 are each arc-shaped, and the guide block 620 is attached to at least one inner sidewall of the guide groove 121 during the sliding of the guide block 620 along the guide groove 121. This can define the rotation locus of the connection structure 120 to accurately guide the vertical beam body 100 into the inside of the refrigerator 1.

In other embodiments, the vertical beam assembly 10 further includes a second fixing base 700, where the second fixing base 700 is disposed at the opening 30 of the refrigerator, and the second fixing base 700 has a second guide groove 710 with a circular arc shape and opening forward. The second guide groove 710 is used to guide the hollow portion 110 into the second guide groove 710 along the second guide groove 710 or to separate from the second guide groove 710 during the opening and closing of the door 20 of the refrigerator 1. The hollow portion 110 has an arc shape.

In this embodiment, the radian corresponding to the second guide groove 710 is not limited, and may be selected according to needs. As a specific example, as shown in fig. 22, the second guide groove 710 has an arc of 90 °, which allows the hollow portion 110 to be completely accommodated in the second guide groove 710.

In other embodiments, the telescoping structure 200 is configured to extend when the connecting structure 120 is rotated to the end of the lead-in section 611, which avoids the extending structure increasing the friction of the lead-in of the mullion body 100, thereby allowing the connecting structure 120 to be smoothly led into the second fixing base 700,

in other embodiments, the central angles of the connection structure 120, the first guide groove 610, the second guide groove 710, and the hollow portion 110 may range from 80 ° to 110 °. This allows the vertical beam body 100 to rotate along the first guide groove 610 in the range of 80 to 110, and allows the connection structure 120 to be completely accommodated in the first guide groove 610. Again, this allows the hollow portion 110 to rotate along the second guide groove 710 and allows the hollow portion 110 to be completely accommodated in the second guide groove 710. This can further reduce the cold leakage of the refrigerator 1.

In other embodiments, the telescopic structure 200 is arc-shaped, the inner side wall of the first guiding groove 610 is adapted to the outer side wall of the connecting structure 120, and the inner side wall of the second guiding groove 710 is adapted to the outer side wall of the telescopic structure 200.

The inner side wall of the first guide groove 610 is matched with the outer side wall of the connecting structure 120, that is, as shown in fig. 26, the inner side wall of the first guide groove 610 is uniformly spaced from the outer side wall of the connecting structure 120, and the gap between the inner side wall of the first guide groove 610 and the outer side wall of the connecting structure 120 is small.

The inner side wall of the second guide groove 710 is matched with the outer side wall of the telescopic structure 200, that is, as shown in fig. 9, the inner side wall of the second guide groove 710 is uniformly spaced from the outer side wall of the hollow portion 110, and the gap between the inner side wall of the second guide groove 710 and the outer side wall of the hollow portion 110 is small. This can avoid the refrigerator 1 from leaking cold, so that the choke effect of the refrigerator 1 is good.
