That is, when the linkage component 400 resists the protrusion, the protrusion squeezes the linkage component 400 to move the linkage component 400 downward along the length direction of the vertical beam body 100 . Otherwise, the linkage assembly 400 moves upward along the length direction of the vertical beam body 100 .

In this embodiment, the specific structure of the end of the linkage component 400 that resists the rotation shaft 300 is not limited and can be selected as needed. For example, the linkage component 400 has a resistance portion 411 that matches the end of the rotation shaft 300 , that is, the matching portion is the resistance portion 411 . As shown in FIGS. 5 to 9 , when the door 20 of the refrigerator 1 is in a closed state, at least one protrusion contacts the protrusion 4111 of the resistance portion 411 . At this time, the linkage component 400 and the telescopic structure 200 move downward to move from the hollow portion 110 Extend inward to achieve wind blocking effect.

As shown in FIG. 10 , when the door 20 of the refrigerator 1 is in an open state, at least one protrusion contacts the recess 4112 of the resistance portion 411 to move the linkage assembly 400 and the telescopic structure 200 upward, and the telescopic structure 200 retracts into the hollow portion 110 . This can reduce the friction force of the telescopic structure 200 so that the vertical beam main body 100 can be rotated out from the refrigerator 1 .

That is, when the door 20 of the refrigerator 1 is in a closed state, the protrusion conflicts with the protrusion 4111 of the resistance portion 411. At this time, the linkage component 400 moves downward, and the telescopic structure 200 also moves downward to achieve the wind blocking effect. When the door body 20 of the refrigerator 1 is in an open state, the protrusion conflicts with the recess 4112 of the resistance portion 411. At this time, the linkage component 400 moves upward, the telescopic structure 200 also moves upward, and the telescopic structure 200 retracts into the hollow portion 110, so as to It is convenient for the vertical beam main body 100 to rotate out of the refrigerator 1 following the door body 20 of the refrigerator 1 . In the vertical beam assembly 10 provided in this embodiment, as the door 20 of the refrigerator 1 is closed, the telescopic structure 200 therein naturally extends to achieve a wind grouping effect. As the door 20 of the refrigerator 1 is opened, the telescopic structure 200 of the vertical beam assembly 10 naturally retracts to facilitate the opening of the door 20 .

In this embodiment, during the process of the refrigerator 1 door 20 from opening to closing, or during the process of the refrigerator 1 door 20 from closing to opening, the angle at which the vertical beam main body 100 rotates is not limited and can be selected according to needs. As a specific embodiment, as shown in FIGS. 7 and 8 , when the door 20 of the refrigerator 1 is from closing to opening, the vertical beam main body 100 rotates 90° counterclockwise. When the door 20 of the refrigerator 1 is opened to closed, the vertical beam main body 100 rotates 90° clockwise.

In this embodiment, the specific components included in the linkage component 400 are not limited and can be selected as needed. As a specific embodiment, as shown in FIG. 6 , the linkage assembly 400 includes a linkage shaft 410 and a linkage structure 430 . In this embodiment, the specific manner in which the linkage assembly 400 causes the telescopic structure 200 to extend from the hollow part 110 or retract into the hollow part 110 is not limited. For example, the linkage component 400 can directly drive the telescopic structure 200 to move up and down, or the linkage component 400 can indirectly drive the telescopic structure 200 to move up and down.

The end of the rotation shaft 300 in the vertical beam assembly 10 provided in this embodiment has at least one protrusion. During the rotation, the rotation shaft 300 can trigger the linkage component 400 to move along the length direction of the vertical beam body 100. The linkage component 400 makes the telescopic structure 200 extend from the hollow part 110 or retract into the hollow part 110 . This allows the vertical beam assembly 10 to naturally extend the telescopic structure 200 when the door 20 of the refrigerator 1 is closed to achieve a wind grouping effect. As the door 20 of the refrigerator 1 is opened, the telescopic structure 200 of the vertical beam assembly 10 naturally retracts to facilitate the opening of the door 20 .

At the same time, the resistance portion 411 can prevent the rotation shaft 300 from rotating at will, that is, the resistance portion 411 limits the rotation of the rotation shaft 300 . When the door 20 of the refrigerator 1 is opened, the vertical beam body 100 loses its restriction, that is, the vertical beam body 100 may rotate due to accidental contact, which makes it difficult to close the door 20 . The conflicting portion 411 can avoid vertical beams The main body 100 can rotate freely to ensure the smooth closing of the door 20 of the refrigerator 1.

In some other embodiments, the at least one protrusion includes first protrusion 310 and second protrusion 320 . The first protrusion 310 is provided on the end surface of the rotating shaft 300 . The second protrusions 320 are disposed on the end surface of the rotating shaft 300 and are equally spaced from the first protrusions 310 along the circumferential direction of the rotating shaft 300 . Since the resisting portion 411 is adapted to the end of the rotating shaft 300, the resisting portion 411 has two protrusions 4111 arranged at equal intervals along its circumferential direction. As shown in FIG. 5 , the first protrusion 310 and the second protrusion 320 respectively conflict with the two protrusions 4111 of the resistance portion 411 , which makes the forces on the linkage component 400 and the telescopic structure 200 relatively balanced.

In some other embodiments, when the door 20 of the refrigerator 1 is opened or closed, the vertical beam body 100 rotates through an angle ranging from 80° to 110°. That is, when the door 20 of the refrigerator 1 is opened and closed, the vertical beam main body 100 rotates 80° to 110° along with the door 20 to rotate out of or into the refrigerator 1 . That is, as shown in Figures 9 and 10, during the transition between the two conflicting states of the rotating shaft 300 and the linkage assembly 400, the vertical beam body 100 rotates through an angle range of 80° to 110°. During this process , the door 20 of the refrigerator 1 completes the opening and closing conversion.

As shown in Figures 1 and 2, if the rotation angle of the vertical beam body 100 is too small, the vertical beam body 100 will be subject to structural interference from the right door body 20. That is, the left door 20 cannot be opened alone, and the left door 20 can only be opened after the right door 20 is opened. If the rotation angle of the vertical beam body 100 is too large, it will not be easy for the vertical beam body 100 to be introduced into the refrigerator 1 when the door 20 of the refrigerator 1 changes from the open state to the closed state. As a specific embodiment, during the opening and closing process of the door 20 of the refrigerator 1, the vertical beam main body 100 rotates through an angle of 90°.

In some other embodiments, the outer peripheral wall of the resisting portion 411 has at least one limiting portion 412 , and the at least one limiting portion 412 cooperates with the vertical beam body 100 to prevent the resisting portion 411 from rotating.

In this embodiment, the shape of the limiting portion 412 is not limited. The limiting portion 412 can prevent the resisting portion 411 from rotating, and allows the limiting portion 412 to move along the length direction of the vertical beam body 100 . As a specific embodiment, as shown in FIG. 6 , the shape of the limiting portion 412 is a strip. Obviously, this is only exemplary and not unique.

In this embodiment, the number of limiting parts 412 is not limited and can be selected as needed. As a specific embodiment, as shown in FIG. 6 , the number of limiting portions 412 is four, and they are evenly distributed along the outer peripheral wall of the resisting portion 411 .

In some other embodiments, each protrusion has a first inclined portion 311 , a connecting portion 312 and a second inclined portion 313 in sequence along the circumferential direction of the rotation shaft 300 . The central angle corresponding to the recess 4112 of the resisting portion 411 is 10° to 20° greater than the central angle corresponding to the connecting portion 312 . The inclination of the second inclined part 313 is greater than the inclination of the first inclined part 311 .

In this embodiment, the shapes of the first inclined part 311, the connecting part 312 and the second inclined part 313 are not limited. As a specific embodiment, as shown in Figures 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 central angle corresponding to the recess 4112 of the resisting portion 411 is 10° to 20° greater than the central angle corresponding to the connecting portion 312 . Therefore, as shown in FIGS. 12 and 13 , when the protrusion is located in the recess 4112 of the resistance portion 411 , there is a flash gap between the first inclined portion 311 and the protrusion 4111 of the resistance portion 411 . That is, when the rotating shaft 300 rotates from FIG. 12 to FIG. 13 , during the first 10° to 20° of rotating the rotating shaft 300 , the protrusion is always located in the recess 4112 of the resisting portion 411 . That is, during this process, the linkage component 400 does not move along the length direction of the vertical beam body 100 . That is, when the door 20 of the refrigerator 1 is closed, the telescopic structure 200 does not extend from the hollow part 110 during the first 10° to 20° of rotation of the vertical beam main body 100 . Optionally, the central angle corresponding to the recess 4112 of the resistance part 411 is 65°, and the central angle corresponding to the connection part 312 is 50°. The central angle corresponding to the recess 4112 of the resistance part 411 is greater than the central angle corresponding to the connection part 312. out 15°. This reduces the friction between the telescopic structure 200 and the refrigerator 1, making it easier for the vertical beam body 100 to rotate into the refrigerator 1.

The inclination of the second inclined part 313 is greater than the inclination of the first inclined part 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 FIGS. 12 and 13 , this facilitates the rotating shaft 300 to rotate along the first inclined portion 311 to switch between two conflicting situations. The inclination of the second inclined portion 313 Larger, the second inclined portion 313 is used to prevent the rotating shaft 300 from rotating arbitrarily.

In this embodiment, the specific range of the central angle corresponding to the first inclined portion 311 and the second inclined portion 313 is not limited and can be selected as needed. As a specific embodiment, as shown in FIGS. 12 and 13 , the central angle corresponding to the first inclined portion 311 is 20°, and the central angle corresponding to the second inclined portion 313 is 5°.

In some other embodiments, the central angle corresponding to the protrusion 4111 of the resisting portion 411 is greater than the corresponding central angle of the protrusion. The specific numerical values of the central angle corresponding to the protrusion 4111 of the conflicting portion 411 and the central angle corresponding to the protrusion are not limited, and the difference between them is not specifically limited either. As shown in FIG. 12 , the central angle corresponding to the protrusion 4111 of the resisting 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 resisting portion 411 is larger than the corresponding central angle of the protrusion, so that the protrusion can stably resist the convex portion 4111 of the resisting portion 411 .

As shown in Figures 14 to 20, when the cooperation between the rotating shaft 300 and the linkage component 400 is pin-shaft cooperation, as a specific embodiment, the outer peripheral wall of the rotating shaft 300 has at least one limiting pin 330, that is, the matching portion It is the limit pin 330. The linkage component 400 has a bearing portion 414 , which is arc-shaped. The bearing portion 414 is sleeved on the outside of the outer peripheral wall of the rotating shaft 300 . The bearing portion 414 has at least one guide portion 415 extending along the circumferential and axial directions of the bearing portion 414 . At least one guide portion 415 is used to arrange at least one limiting pin 330 therein in one-to-one correspondence, and is configured to move the linkage assembly 400 along the length direction of the vertical beam body 100 when the rotation shaft 300 rotates.

The outer peripheral wall of the rotating shaft 300 has at least one limiting pin 330. As a specific embodiment, as shown in FIG. 20, the outer peripheral wall of the rotating shaft 300 has two limiting pins 330. Obviously, this is only exemplary and not unique. For example, the number of limiting pins 330 may be one, three, four or more. In this embodiment, the limiting pin 330 and the rotating shaft 300 may be integrally formed or have a separate structure. The shape of the limiting pin 330 is not specifically limited and can be selected as needed.

The linkage component 400 is disposed in the vertical beam body 100 , and the linkage component 400 is configured to move only along the length direction of the vertical beam body 100 . That is, the linkage component 400 can only move along the longitudinal direction of the vertical beam body 100 , that is, the linkage component 400 can only move up and down.

In this embodiment, the specific components included in the linkage component 400 are not limited and can be selected as needed. As a specific embodiment, as shown in FIG. 18 , the linkage assembly 400 includes a linkage shaft 410 and a linkage structure 430 . In this embodiment, the specific manner in which the linkage assembly 400 causes the telescopic structure 200 to extend from the hollow part 110 or retract into the hollow part 110 is not limited. For example, the linkage component 400 can directly drive the telescopic structure 200 to move up and down, or the linkage component 400 can indirectly drive the telescopic structure 200 to move up and down.

In this embodiment, the linkage component 400 has a bearing portion 414, and the bearing portion 414 is arc-shaped. In this embodiment, the specific shape of the bearing portion 414 is not limited. For example, the bearing portion 414 may include an arc, a semi-cylindrical shape, or a cylinder. As a specific embodiment, as shown in FIG. 18 , the bearing portion 414 includes a cylinder. Obviously, this is only exemplary and not unique.

In this embodiment, the distance between the bearing inner peripheral wall and the outer peripheral wall of the rotation shaft 300 is not limited and can be selected as needed. As shown in FIG. 17 , the distance between the bearing inner peripheral wall and the outer peripheral wall of the rotating shaft 300 is small and can be ignored.

In this embodiment, the specific number of guide parts 415 is not limited and can be selected as needed. As a specific embodiment, as shown in FIG. 19 , the number of guide parts 415 is two. Obviously, this is only exemplary and not unique. For example, the number of guide parts 415 may be one, three, four or more.

In this embodiment, the guide part 415 and the carrying part 414 may be integrally formed or have a separate structure. For example, the guide part 415 may be a blind groove or a through groove opened on the bearing part 414 .

In this embodiment, the specific shape of the guide portion 415 is not limited. As shown in FIG. 19 , the guide portion 415 can extend along the circumferential and axial directions of the bearing portion 414 . As shown in Figure 19, each guide portion 415 includes a first section 4151, a middle section 4152, and a second section 4153 that are sequentially connected along its extension direction. The first section 4151 and the second section 4153 are horizontal sections, and the middle section 4152 Inclined arrangement, wherein the first section 4151 is close to the telescopic structure 200. Obviously, this is only illustrative and not exclusive.

During the rotation of the rotating shaft 300, since the linkage component 400 cannot rotate, the linkage component 400 With the cooperation of the limiting pin 330 and the guide part 415, it moves along the length direction of the vertical beam body 100.

Specifically, during the closing process of the door 20 of the refrigerator 1, the limiting pin 330 moves from the first section 4151 to the second section 4153. The linkage component 400 moves toward the telescopic structure 200, that is, moves downward. The telescopic structure 200 moves downward to extend from the hollow portion 110 to achieve a wind blocking effect.

When the door 20 of the refrigerator 1 is opened, the limiting pin 330 moves from the second section 4153 to the first section 4151. The linkage component 400 moves away from the telescopic structure 200 , that is, moves upward, and the telescopic structure 200 retracts into the hollow part 110 . This can reduce the friction force of the telescopic structure 200 so that the vertical beam main body 100 can be rotated out from the refrigerator 1 .

In the vertical beam assembly 10 provided in this embodiment, as the door 20 of the refrigerator 1 is closed, the telescopic structure 200 therein naturally extends to achieve the wind grouping effect. As the door 20 of the refrigerator 1 is opened, the telescopic structure 200 of the vertical beam assembly 10 naturally retracts to facilitate the opening of the door 20 .

The vertical beam assembly 10 provided in this embodiment cooperates with the pin grooves of the rotating shaft 300 and the linkage assembly 400. During the closing process of the door body 20, the rotation of the rotating shaft 300 can touch the linkage assembly 400 along the length of the vertical beam body 100. By moving in the direction, the linkage assembly 400 causes the telescopic structure 200 to extend from the hollow part 110 or retract into the hollow part 110 . This allows the vertical beam assembly 10 to naturally extend the telescopic structure 200 when the door 20 of the refrigerator 1 is closed to achieve a wind grouping effect. As the door 20 of the refrigerator 1 is opened, the telescopic structure 200 of the vertical beam assembly 10 naturally retracts to facilitate the opening of the door 20 .

In some other embodiments, each guide portion 415 is a groove opened in the peripheral wall of the bearing portion 414 . This makes the vertical beam assembly 10 structurally simple.

In some other embodiments, the central angle corresponding to each guide portion 415 ranges from 80° to 100°. That is, when the door 20 of the refrigerator 1 is opened or closed, the vertical beam main body 100 rotates through an angle range of 80° to 110°. That is, when the door 20 of the refrigerator 1 is opened and closed, the vertical beam main body 100 rotates 80° to 110° along with the door 20 to rotate out of or into the refrigerator 1 . That is, the limiting pin 330 moves 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 main body 100 rotates through an angle range of 80° to 110°. During this process , the door 20 of the refrigerator 1 completes the opening and closing conversion.

As shown in Figures 1 and 2, if the rotation angle of the vertical beam body 100 is too small, the vertical beam body 100 will be subject to structural interference from the right door body 20. That is, the left door 20 cannot be opened alone, and the left door 20 can only be opened after the right door 20 is opened. If the rotation angle of the vertical beam body 100 is too large, it will not be easy for the vertical beam body 100 to be introduced into the refrigerator 1 when the door 20 of the refrigerator 1 changes from the open state to the closed state. As a specific embodiment, as shown in Figures 24 to 26, during the opening and closing process of the door 20 of the refrigerator 1, the vertical beam main body 100 rotates through an angle of 90°.

The first section 4151 is close to the telescopic structure 200, and the first section 4151 is horizontal. section, the middle section 4152 is arranged at an angle.

When the door 20 of the refrigerator 1 is closed, the limiting pin 330 moves from the first section 4151 to the second section 4153. The first section 4151 is a horizontal section, that is, during the movement of the limiting pin 330 in the first section 4151, the positions of the linkage component 400 and the telescopic structure 200 do not change. That is, during this process, the linkage component 400 does not move along the length direction of the vertical beam body 100 . That is, when the door 20 of the refrigerator 1 is closed and the vertical beam main body 100 rotates in the early stage, the telescopic structure 200 does not extend from the hollow part 110 . This reduces the friction between the telescopic structure 200 and the refrigerator 1, making it easier for the vertical beam body 100 to rotate into the refrigerator 1.

When the door 20 of the refrigerator 1 is opened, the limiting pin 330 moves from the second section 4153 to the first section 4151. When the door 20 of the refrigerator 1 is opened, the vertical beam body 100 loses its restriction, that is, the vertical beam body 100 will be If the door 20 is accidentally touched and rotated, it will be difficult to close the door 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 avoid random rotation of the vertical beam main body 100 and ensure the smooth closing of the door 20 of the refrigerator 1.

In some other embodiments, the first section 4151 is close to the telescopic structure 200, and the central angle corresponding to the first section 4151 ranges from 10° to 20°. When the door 20 of the refrigerator 1 is closed and the rotation shaft 300 rotates for the first 10° to 20°, the limit pin 330 is always located at the first section 4151. That is, during this process, the linkage component 400 does not move along the length direction of the vertical beam body 100 . That is, when the door 20 of the refrigerator 1 is closed, the telescopic structure 200 does not extend from the hollow part 110 during the first 10° to 20° of rotation of the vertical beam main body 100 . This reduces the friction between the telescopic structure 200 and the refrigerator 1, making it easier for the vertical beam body 100 to rotate into the refrigerator 1.

When the telescopic structure 200 retracts the hollow part 110, that is, when the linkage shaft 410 moves upward, and when the linkage shaft 410 moves toward the rotation shaft 300, the compressed first spring 420 provides upward power to the linkage shaft 410 for connection. The moving shaft 410 moves upward.

In some other embodiments, the vertical beam assembly 10 for the door body 20 of the refrigerator 1 further includes a plurality of second springs 500 .

When the telescopic structure 200 extends out of the hollow part 110 , the compressed plurality of second springs 500 provide power to the telescopic structure 200 so that the telescopic structure 200 extends out of the hollow part 110 . The plurality of second springs 500 are evenly arranged so that the telescopic structure 200 is evenly stressed, so that the telescopic structure 200 can smoothly extend or retract into the hollow portion 110 multiple times.

The limiting portion 412 can prevent the resisting portion 411 from rotating, and allows the limiting portion 412 to move along the length direction of the vertical beam body 100 . As a specific embodiment, as shown in FIG. 18 , the shape of the limiting portion 412 is a strip. Obviously, this is only exemplary and not unique.

In this embodiment, the number of limiting parts 412 is not limited and can be selected as needed. As a specific embodiment, as shown in FIG. 18 , the number of limiting portions 412 is four, and they are evenly distributed along the outer peripheral wall of the resisting portion 411 .

In some other embodiments, the ends of the vertical beam main body 100 along its length direction form an arc-shaped connection structure 120 . The vertical beam assembly 10 also includes a first fixing base 600, which is disposed at the opening 30 of the refrigerator. The first fixed seat 600 has an arc-shaped first guide groove 610 with an opening facing forward. The first fixing seat 600 is used to guide the connecting structure 120 into the first guide groove 610 along the inner wall of the first guide groove 610 or to disengage from the first guide groove 610 during the opening and closing process of the door 20 of the refrigerator 1 .
