As shown in fig. 1 to 15, the present embodiment provides a vertical beam assembly 10 for a refrigerator door 20, the vertical beam assembly 10 including a vertical beam 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 the vertical beam body 100, and the rotation shaft 300 is configured to rotatably provide the vertical beam body 100 to the refrigerator door 20, and an outer circumferential wall of the rotation shaft 300 has at least one guide portion 310 extending in a circumferential direction and an axial direction thereof.

The interlock assembly 400 is disposed in the vertical beam body 100 and is configured to be movable in the longitudinal direction of the vertical beam body 100 so as to extend or retract the telescopic structure 200 from or into the hollow portion 110. The linkage assembly 400 has at least one limiting pin 411, and the at least one limiting pin 411 is disposed in the at least one guiding portion 310 in a one-to-one correspondence, and is configured to move along the at least one guiding portion 310 when the rotation shaft 300 rotates, so that the linkage assembly 400 moves along the length direction of the vertical beam main body 100.

In the present embodiment, the number of refrigerator door 20 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 refrigerator door 20 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 refrigerator door 20 is closed, as shown in fig. 1 and 2, the vertical beam body 100 is located between the left and right door 20 and 20 to prevent cool air from leaking out from between the left and right door 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 to 6, 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. 6, 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. 9, as a specific embodiment, the specific shape of the telescopic structure 200 is an arc shape, and the outer peripheral wall of the telescopic structure 200 is fitted to the inner wall of the hollow portion 110, that is, the outer peripheral wall of the telescopic structure 200 is attached to the inner peripheral wall of the hollow portion 110. As shown in fig. 6, the telescopic structure 200 moves up and down along the inner wall of the hollow 110. The telescopic structure 200 with the shape has better choke effect.

In the present embodiment, the rotation shaft 300 is rotatably provided in the vertical beam body 100. During the opening of the refrigerator door 20, the vertical beam body 100 rotates about the rotation shaft 300 to be unscrewed from the refrigerator 1. During the closing of the refrigerator door 20, 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 refrigerator door 20 is not limited, and may be selected as desired.

As a specific example, the rotation shaft 300 is rotatably provided at one side of the girder 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 outer circumferential wall of the rotation shaft 300 has at least one guide portion 310, and the specific number of the guide portions 310 is not limited and may be selected as needed. As a specific example, as shown in fig. 7, the number of the guide portions 310 is one. It will be apparent that this is by way of example only and not by way of example only. For example, the number of the guide portions 310 may be two, three, four, or more.

In this embodiment, the guide portion 310 and the rotation shaft 300 may be integrally formed or be a split structure. For example, the guide portion 310 may be a blind groove or a through groove formed on the rotation shaft 300.

In the present embodiment, the specific shape of the guide portion 310 is not limited, and as shown in fig. 7, the guide portion 310 may extend along the circumferential direction and the axial direction of the rotation shaft 300. As shown in fig. 7, each guide 310 includes a first section 311, an intermediate section 312, and a second section 313 connected in sequence along the extending direction thereof. The first section 311 and the second section 313 are horizontal sections, and the middle section 312 is obliquely arranged, wherein the first section 311 is far away from the telescopic structure 200. It will be apparent that this is by way of example only and not by way of example only.

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 example, as shown in fig. 8, the linkage assembly 400 includes a conductive segment 410 and a connecting segment 420. 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 the present embodiment, the number of the limiting pins 411 is not limited, and may be selected as needed. As a specific embodiment, as shown in fig. 8, the linkage assembly 400 has a limiting pin 411. It will be apparent that this is by way of example only and not by way of example only. For example, the number of the stopper pins 411 may be two, three, four or more. In the present embodiment, the limiting pin 411 and the linkage assembly 400 may be integrally formed or be a split structure. The shape of the stopper pin 411 is not particularly limited and may be selected as needed.

During the rotation of the rotation shaft 300, the interlocking assembly 400 moves along the length direction of the vertical beam body 100 with the cooperation of the limiting pin 411 and the guide part 310. Specifically, the stopper pin 411 moves from the first section 311 to the second section 313 during closing of the refrigerator door 20. 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 refrigerator door 20, the stopper pin 411 moves from the second section 313 to the first section 311. 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 with the refrigerator door 20, and the telescopic structure 200 thereof naturally extends to achieve the wind assembly effect. The vertical beam assembly 10 is naturally retracted by the telescopic structure 200 therein as the refrigerator door 20 is opened, so that the door 20 is opened.

In the present embodiment, the angle through which the vertical beam body 100 rotates is not limited in the process of opening the refrigerator door 20 to closing or in the process of closing the refrigerator door 20 to opening, and may be selected according to need. As a specific example, as shown in fig. 3 to 7, the vertical beam body 100 is rotated 90 ° counterclockwise during the process of closing to opening the refrigerator door 20. The vertical beam body 100 is rotated clockwise by 90 ° during the process of opening to closing the refrigerator 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. The vertical beam assembly 10 is naturally extended to achieve a wind-assembling effect as the refrigerator door 20 is closed. The vertical beam assembly 10 is naturally retracted by the telescopic structure 200 therein as the refrigerator door 20 is opened, so that the door 20 is opened.

In other embodiments, each guide 310 is a guide groove formed in the peripheral wall of the rotating shaft 300. The guide grooves may be blind grooves or through grooves. This makes the structure of the rotation shaft 300 simple.

In other embodiments, each guide 310 corresponds to a central angle in the range of 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 refrigerator door 20. That is, during the opening and closing of the refrigerator door 20, the vertical beam body 100 rotates 80 ° to 110 ° with the door 20 to be rotated out of the refrigerator 1 or screwed into the refrigerator 1. That is, the stopper pin 411 is moved from the second section 313 to the first section 311 or from the first section 311 to the second section 313, and the vertical beam body 100 is rotated through an angle range of 80 ° to 110 °, in which the refrigerator door 20 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 refrigerator door 20 is opened to closed. As a specific example, as shown in fig. 13 to 15, the vertical beam body 100 is rotated by 90 ° during the opening and closing of the refrigerator door 20.

In other embodiments, each guide 310 includes a first segment 311, an intermediate segment 312, and a second segment 313 connected in sequence along its direction of extension. The first section 311 and the second section 313 are horizontal sections, the middle section 312 is obliquely arranged, and the first section 311 is far away from the telescopic structure 200.

During the closing of the refrigerator door 20, the stopper pin 411 moves from the first section 311 to the second section 313. The first section 311 is a horizontal section, that is, the positions of the linkage assembly 400 and the telescopic structure 200 are not changed in the moving process of the first section 311 by the limiting pin 411. 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 refrigerator door 20. 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 refrigerator door 20, the stopper pin 411 moves from the second section 313 to the first section 311. In the case where the refrigerator door 20 is opened, the vertical beam body 100 loses restriction, that is, the vertical beam body 100 rotates due to a false touch, which makes it difficult to close the door 20. The first section 311 is located at the upper end, and the first section 311 is a horizontal section, and the middle section 312 is an inclined section, which can prevent the vertical beam main body 100 from being rotated at will, so as to ensure smooth closing of the refrigerator door 20.

In other embodiments, the first segment 311 corresponds to a central angle in the range of 10 ° to 20 °. In the process of closing the refrigerator door 20, the limiting pin 411 is always located at the first section 311 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 refrigerator door 20, the vertical beam body 100 rotates by the first 10 ° to 20 °, and the telescopic structure 200 does not protrude from the inside of the hollow portion 110. 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, the rotation shaft 300 is located in one side of the vertical beam body 100, and the linkage assembly 400 is configured to extend from the rotation shaft 300 to the middle of the telescopic structure 200 and connect with the middle of the telescopic structure 200 to uniformly stress the telescopic structure 200.

In the present embodiment, one side of the vertical beam body 100 is not particularly limited, and may be selected as needed. For example, one side of the vertical beam body 100 may be the left side of the vertical beam body 100 or the right side of the vertical beam body 100. As shown in fig. 3 and 5, one side of the vertical beam body 100 refers to the left side of the vertical beam body 100, which is obviously only exemplary.

In the present embodiment, the specific manner of extending the linkage assembly 400 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, so that the telescopic structure 200 is uniformly stressed.

In other embodiments, the linkage assembly 400 includes a conductive segment 410 and a connecting segment 420, a first end of the conductive segment 410 having a stop pin 411, and a second end of the conductive segment 410 being located at an end of the mullion body 100 corresponding to a middle portion of the telescoping structure 200. The connection section 420 is disposed at the second end of the conductive section 410, and passes through the end of the vertical beam body 100 along the length direction of the vertical beam body 100 to be connected with the middle of the telescopic structure 200.

In the present embodiment, the shape of the conductive segment 410 is not particularly limited, and may be selected as needed. As shown in fig. 8, the conductive segment 410 is flat, which is obviously exemplary only and not exclusive. As shown in fig. 6, the conductive segment 410 extends from the left side of the vertical beam body 100 toward the right side of the vertical beam body 100 and then toward the rear side of the vertical beam body 100 such that the second end of the conductive segment 410 is located at the upper end of the middle of the telescopic structure 200.

In the present embodiment, the shape of the connection section 420 is not particularly limited, and may be selected as needed. As shown in fig. 8, the connecting section 420 is cylindrical, it being apparent that this is by way of example only and not by way of limitation. In this embodiment, the connection section 420 passes through the end of the vertical beam body 100 along the length direction of the vertical beam body 100 to be connected with the middle of the telescopic structure 200, so that the telescopic structure 200 is uniformly stressed.

In other embodiments, as shown in fig. 4, the conductive segment 410 extends in a horizontal direction, which makes the linkage assembly 400 simple in structure and small in space occupation. As shown in fig. 6 and 9, the telescopic structure 200 has a clamping portion 210, and the connection section 420 is clamped in the clamping portion 210, which makes the linkage assembly 400 easy to assemble.

In other embodiments, the mullion assembly 10 further comprises a plurality of springs 500, the plurality of springs 500 being disposed uniformly within the telescoping structure 200, the plurality of springs 500 being configured to connect an end of the mullion body 100 and the telescoping structure 200, the plurality of springs 500 being configured to be compressed when the telescoping structure 200 is retracted within the hollow portion 110.

In other embodiments, the plurality of springs 500 are compressed to store force as the telescoping structure 200 is retracted into the hollow 110. When the telescopic structure 200 is extended out of the hollow portion 110, the plurality of springs 500 apply a pushing force to the telescopic structure 200 so that the telescopic structure 200 is uniformly stressed.

In other embodiments, the ends of the vertical beam body 100 opposite the hollow 110 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 seat 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 refrigerator door 20.

In the present embodiment, the end portions of the vertical beam body 100 opposite to the hollow portion 110 form an arc-shaped connection structure 120, that is, the both ends of the vertical beam body 100 in the length direction thereof form the connection structure 120 and the hollow portion 110, respectively. As a specific example, the hollow portion 110 is located at the bottom end of the girder body 100, and the connection structure 120 is located at the top 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. 10, 13, 14 and 15, the circular arc-shaped connection structure 120 corresponds to a central angle of 90 °.

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. 13, 14 and 15, a gap between the first guide groove 610 and the connection structure 120 is small and relatively uniform, which further prevents the 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. 10, 13, 14 and 15, 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., as shown in fig. 13, 14 and 15, 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. 13, 14 and 15, the angle of the central angle corresponding to the lead-in section 611 is 15 °. The first segment 311 of the guide 310 corresponds to a central angle in the range of 10 ° to 20 °. The two angles are the same, which makes it easier to introduce the connecting structure 120 into the first fixing base 600 at the initial stage. 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 refrigerator door 20.

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. 13, 14 and 15, 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. 3, 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. 13, 14 and 15, 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. 13, 14 and 15 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. 13, 14 and 15, 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. 13, 14 and 15, 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 be separated from the second guide groove 710 during the opening and closing of the refrigerator door 20. 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. 11, 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 connection structure 120, that is, as shown in fig. 13, 14 and 15, the inner side wall of the first guide groove 610 is uniformly spaced from the outer side wall of the connection structure 120, and the gap between the inner side wall of the first guide groove 610 and the outer side wall of the connection 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, the inner side wall of the second guide groove 710 and the outer side wall of the hollow portion 110 are uniformly spaced, 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 smaller. This can avoid the refrigerator 1 from leaking cold, so that the choke effect of the refrigerator 1 is good.
