Description

Technical Field

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

[0002] In the current refrigerator market, cross-door and French refrigerators account for a high proportion of the entire refrigerator market.

[0003] Cross-door and French refrigerators include two refrigerated doors on the left and right sides. The flip beam is generally installed on the left or right refrigerated door. The function of the flip beam is to block the gap between the left and right doors, making the compartment as airtight as possible to prevent condensation at the door gap. When the door is closed, the flip beam flips to a state parallel to the two door bodies, and the door gaps of the left and right refrigerated doors are just in the middle of the flip beam. When the refrigerated door with the flip beam needs to be opened, the flip beam will flip to a state perpendicular to the door body as the door body on that side is opened.

[0004] When a user opens the door to take out food from the refrigerated drawer, most refrigerators on the market currently require both doors to be opened before the drawer on any side can be pulled out and the food can be taken out. Alternatively, only the door on the side with the flip beam can be opened (accompanied by the flip beam flipping), and the drawer on the corresponding side can be pulled out. However, when only the refrigerated door on the side without the flip beam is opened, the refrigerated drawer on that side cannot be opened due to the obstruction of the flip beam, resulting in certain inconvenience in taking out and putting out food. Utility Model Content

DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0053] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0054] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0055] In order to solve the technical problem that in the prior art, since the flip beam is installed on the refrigerator door body on one side, the door body on the side not equipped with the flip beam cannot drive the flip beam to flip when opening and closing, which affects the opening of the drawer on this side, thereby causing inconvenience in taking and placing food, the present application provides a transmission assembly, a flip beam mechanism and a refrigerator, which can drive the flip beam body 30 to flip when opening and closing the door body not equipped with the flip beam body 30, so that the drawer on this side can be opened to take and place food, thereby improving the convenience of taking and placing food.

[0056] The present application embodiment provides a transmission component, such as Figures 1 to 5As shown, the transmission assembly mainly includes a base 60, a transmission guide rod 61, a transmission stop rod 63 and a transmission member. The base 60 is provided with a first arc guide groove, and the curvature of the first arc guide groove is greater than or equal to π / 2; the transmission guide rod 61 is slidably connected to the base 60, and can be slid out or retracted relative to the base 60. The transmission stop rod 63 is rotationally connected to the base 60, and a first guide shaft 631 is provided at one end of the transmission stop rod 63 away from the rotationally connected base 60. The first guide shaft 631 passes through the first arc guide groove and protrudes from the base 60. The first guide shaft 631 can slide in the first arc guide groove as the transmission stop rod 63 rotates. The transmission member is transmission-connected between the transmission guide rod 61 and the transmission stop rod 63, and is used to convert the linear sliding of the transmission guide rod 61 relative to the base 60 into the rotation of the transmission stop rod 63.

[0057] refer to Figure 4 When the transmission assembly is in the first state, when the transmission guide rod 61 slides toward the base 60 and is retracted, the transmission stop rod 63 is driven by the transmission member to rotate along the first direction, and the first guide shaft 631 rotates toward the first end of the first arc-shaped guide groove. Figure 5 When the transmission assembly is in the second state, when the transmission guide rod 61 is driven to extend relative to the base 60, the transmission blocking rod 63 is driven to rotate in the second direction through the transmission component, and the first guide shaft 631 moves toward the second end of the first arc groove.

[0058] Taking the left door body 10 of the refrigerator as being connected to the flip beam body 30 and the right side as being not connected to the flip beam body 30, the transmission assembly can be installed between the flip beam body 30 and the right door body 20, and the flip beam body 30 can be driven to move by means of the first guide shaft 631.

[0059] Combined with reference Figures 6 to 11 When the left door 10 and the right door 20 of the refrigerator are both in the closed state, the flip beam body 30 is in a state parallel to the left door 10 and the right door 20 and corresponds to the sealing of the door gaps of the two. Due to the abutment limit of the right door 20, the transmission guide rod 61 is in a state of being retracted from the base 60, and the first guide shaft 631 is located at the first end of the first arc-shaped guide groove and forms a match with the flip beam body 30.

[0060] When the right door body 20, i.e., the door body on the side where the flip beam body 30 is not provided, is opened, the right door body 20 no longer abuts against the transmission guide rod 61, and the transmission guide rod 61 can slide out of the base 60. The transmission guide rod 61 drives the transmission stop rod 63 to rotate along the second direction through the transmission member, and the first guide shaft 631 moves along the first arc guide groove toward the second end of the first arc guide groove, driving the flip beam body 30 to flip from the state of parallelly fitting the left door body 10 and the right door body 20. Since the curvature of the first arc guide groove is greater than or equal to π / 2, that is, the first guide shaft 631 can drive the flip beam to flip by an angle greater than or equal to π / 2, so that the flip beam body 30 can flip to the left side of the door gap, avoiding the obstruction of the right drawer, so that the right drawer can be opened to take out food.

[0061] When the right door body 20 is closed, the right door body 20 abuts against the transmission guide rod 61, the transmission guide rod 61 slides back to the base 60, the transmission guide rod 61 drives the transmission stop rod 63 to rotate along the first direction through the transmission component, and the first guide shaft 631 moves along the first arc guide groove toward the first end of the first arc guide groove. The first guide shaft 631 drives the flip beam body 30 to flip again to a position that fits the door gap between the left door body 10 and the right door body 20 to ensure the sealing performance. The setting of the transmission assembly enables the opening and closing of the door body on the side where the flip beam body 30 is not assembled to drive the flip beam body 30 to flip, thereby improving the convenience of taking and putting food.

[0062] In some embodiments, the transmission member may be a transmission gear 62, and the axis of the transmission gear 62 is rotatably connected to the base 60. The transmission guide rod 61 is slidably connected to the base 60, and the base 60 may be provided with a sliding guide groove that cooperates with the transmission guide rod 61, and the sliding guide groove is used to guide and limit the sliding of the transmission guide rod 61 relative to the base 60. In order to realize the conversion of the linear reciprocating sliding of the transmission guide rod 61 into the rotation of the transmission gear 63 relative to the base 60 by means of the transmission gear 62, a rack meshing with the transmission gear 62 is provided on the side of the transmission guide rod 61 facing the transmission gear 62, and the transmission gear 62 is driven to reciprocate through the meshing of the rack and the transmission gear 62. A rotating shaft is provided at one end of the transmission guide rod 61 and is rotatably connected to the base 60 through the rotating shaft, and a driven gear is coaxially arranged at the rotating shaft of the transmission gear 63, and the driven gear is meshed with the transmission gear 62, and the first guide shaft 631 is arranged at one end of the transmission gear 63 away from its rotating shaft.

[0063] When the transmission guide rod 61 slides relative to the base 60, the rack and the transmission gear 62 interact with each other to drive the transmission gear 62 to rotate, and the transmission gear 62 and the driven gear engage with each other and the driven gear rotates around the rotating shaft, thereby converting the telescopic movement of the transmission guide rod 61 into the rotation of the transmission blocking rod 63 and the first guide shaft 631 along the first arc guide groove around the rotating shaft, and driving the flip beam body 30 to flip through the first guide shaft 631.

[0064] The transmission guide rod 61 and the transmission stop rod 63 are connected by the rack, the transmission gear 62 and the driven gear, thereby ensuring the reliability of the transmission structure. In some other embodiments, the transmission member may also adopt a crank-connecting rod mechanism. The present application does not limit the specific structure of the transmission member, and any member that can convert the linear motion of the transmission guide rod 61 into the transmission stop rod 63 is applicable to the present application.

[0065] Furthermore, the transmission assembly provided in the embodiment of the present application also includes an elastic member that drives the transmission guide rod 61 to slide and extend relative to the base 60. It is understandable that the elastic member can be directly connected to the transmission guide rod 61 and drive the transmission guide rod 61 to slide and extend relative to the base 60, or the transmission guide rod 61 can be extended by driving the transmission gear 62. Exemplarily, the elastic member can include at least one of a first elastic member 64 and a second elastic member, the first elastic member 64 is a spring and is sleeved on the transmission guide rod 61, and the two ends of the spring are compressed and abutted between the base 60 and the transmission guide rod 61. The second elastic member can be a torsion spring torsionally connected between the transmission gear 62 and the base 60, and the torsion spring has a tendency to drive the transmission gear 62 to rotate and drive the transmission guide rod 61 to slide and extend relative to the base 60.

[0066] To illustrate the working principle of the first elastic member 64, after the right door body 20 is opened and loses the contact limit with the transmission guide rod 61, the elastic force of the first elastic member 64 drives the transmission guide rod 61 to extend relative to the base 60, and drives the transmission stop rod 63 to rotate in the second direction through the transmission gear 62. The second guide shaft 32 moves to the second end of the first arc-shaped guide groove and drives the flip beam body 30 to flip to a state perpendicular to the left door body 10, so that the flip beam body 30 no longer blocks the right drawer, and the right drawer can be freely pulled out and pushed back, which is convenient for food to be taken in and out. When closing the right door body 20, the transmission guide rod 61 is pushed back to the base 60, the first elastic member 64 is compressed again, and the first guide shaft 631 moves to the first end of the first arc-shaped guide groove, driving the flip beam body 30 to flip to a state of fitting the left door body 10 and the right door body 20. Figure 6 and Figure 7 .

[0067] By setting the elastic member to a structure composed of a first elastic member 64 and a second elastic member, the possibility of failure of the elastic member is reduced, so that the transmission guide rod 61 can slide out relative to the base 60, ensuring that when the right door body 20 is opened, the transmission assembly can automatically drive the flip beam body 30 to flip and avoid the position, avoiding affecting the pulling and drawing of the right drawer, thereby improving the convenience of use.

[0068] The present application also provides a flip beam mechanism, including a flip beam body 30, a hinge 40, a flip guide block 50 and a transmission assembly provided in the above embodiment. Figures 6 to 9As shown, the flip beam body 30 is a long strip structure with a rectangular cross section and vertically connected to the refrigerator door body. The anti-collision beam body has a state of being perpendicular to the left door body 10 and the right door body 20, and a state of being parallel to the left door body 10 and the right door body 20. The flip beam body 30 can be rotatably connected to the left door body 10 through the hinge 40, that is, when the left door body 10 is opened and closed, it can drive the flip beam to switch between the state of being perpendicular and being in contact with the left door body 10; and when the right door body 20 is opened and closed, the flip beam body 30 can be driven to flip through the transmission component.

[0069] Combined with reference Figures 10 to 14 , the flip guide block 50 and the transmission assembly are respectively arranged at the two ends of the flip beam body 30. Exemplarily, the flip guide block 50 can be fixed at the top of the flip beam body 30, and the transmission assembly can be fixed at the bottom of the flip beam body 30. The bottom end of the flip beam body 30 can be provided with a transmission guide groove 31, and the transmission guide groove 31 is a U-shaped structure with an opening on the side wall, so that the flip beam body 30 can be matched or separated with the first guide shaft 631. When only the left door body 10 is opened, since the transmission guide groove 31 is an open structure with an opening on the side wall, the flip beam body 30 can be separated from the first guide shaft 631 without affecting the opening of the left door body 10. When the right door body 20 needs to be opened and closed, the transmission assembly drives the flip beam body 30 to flip through the interaction between the first guide shaft 631 and the side wall of the transmission guide groove 31.

[0070] A flip guide structure is provided at both ends of the flip guide block 50 and the flip beam body 30, and the flip guide structure is used to guide the flipping of the flip beam body 30 to ensure that the flip beam body 30 can perform corresponding flipping regardless of opening or closing the left door body 10 or the right door body 20, and can cooperate or separate with the flip guide block 50.

[0071] The transmission assembly is provided with a transmission guide rod 61 on one side thereof, which is aligned with the right door body 20 of the refrigerator, to ensure that when the right door body 20 is opened, the transmission guide rod 61 can slide out relative to the base 60, and then cooperate with the flip beam body 30 through the transmission gear 62, the transmission stop rod 63 and the first guide shaft 631, to drive the flip beam body 30 to flip to a state perpendicular to the left door body 10, without affecting the pulling and drawing of the right drawer. When the right door body 20 is closed, the transmission guide rod 61 is squeezed to slide back to the base 60, and then cooperate with the flip beam body 30 through the transmission gear 62, the transmission stop rod 63 and the first guide shaft 631, to drive the flip beam body 30 to flip to a state parallel to the left door body 10 and the right door body 20, and seal the door gap between the left door body 10 and the right door body 20.

[0072] like Figure 12 to Figure 14As shown, the above-mentioned flip guide structure usually adopts a structure in which a guide shaft and a guide groove cooperate, and the guide shaft and the guide groove can be respectively arranged on the flip beam body 30 and the flip guide block 50. For example, the top end of the flip beam body 30 is provided with a second guide shaft 32 protruding upward; the lower end surface of the flip guide block 50 is provided with a second arc guide groove 51, a third arc guide groove 52 and a fourth guide groove 53. The second arc guide groove 51 and the fourth guide groove 53 are connected to the side of the flip guide block 50, so that the second guide shaft 32 and the flip guide block 50 can be matched or separated from each other, and the two ends of the third arc guide groove 52 are connected to the second arc guide groove 51 and the fourth guide groove 53 respectively.

[0073] The second arc guide groove 51 is used to cooperate with the second guide shaft 32 to drive the flip beam body 30 to flip when the left door body 10 is opened and closed separately. The second arc guide groove 51 is arranged close to the left door body 10, and the concave side of the second arc guide groove 51 is arranged toward the rotating shaft of the left door body 10; when the left door body 10 is opened, the left door body 10 pulls the flip beam body 30 to move through the hinge 40, and the second guide shaft 32 moves along the second arc guide groove 51 and exits the flip guide block 50. While the second guide shaft 32 moves, it drives the flip beam body 30 to flip from a state parallel to the left door body 10 to a state perpendicular to the left door body 10. The semi-open flip guide groove at the bottom of the flip beam body 30 can be separated from the first guide shaft 631 of the transmission assembly, which does not affect the opening of the left door body 10; the closing process of the left door body 10 is opposite to the above process.

[0074] The third arc guide groove 52 is substantially opposite to the first arc guide groove in the vertical direction, and the two extend in substantially the same direction. When only the right door body 20 is opened, the transmission assembly drives the first guide shaft 631 to move in the first arc guide groove, while driving the flip beam body 30 to flip from a state of being parallel to the left door body 10 and the right door body 20 to a state perpendicular to the left door body 10, and the flip beam body 30 drives the second guide shaft 32 to slide along the third arc guide groove 52 until it slides to the end of the third arc guide groove 52 away from the second arc guide groove 51, that is, connected to the fourth guide groove 53. At this time, the flip beam body 30 is in a state perpendicular to the left door body 10, and the left door body 10 can be opened at the same time. The second guide shaft 32 is separated from the flip guide block 50 along the fourth guide groove 53, which does not affect the opening of the left door body 10. Since the flip beam body 30 is already in a state perpendicular to the left door body 10, the second guide shaft 32 and the fourth guide groove 53 do not need to cooperate to drive the flip beam body 30 to flip. Therefore, the fourth guide groove 53 can be a straight groove or an arc-shaped groove with the concave side facing the rotating shaft of the left door body 10. It is only necessary to ensure that the second guide shaft 32 can be separated from or matched with the flip guide block 50 along the fourth guide groove 53.

[0075] That is, the flip beam mechanism provided in the embodiment of the present application is installed on the refrigerator door body, and through the matching structure of the flip guide block 50 and the transmission assembly with the flip beam body 30, it is possible to open the left door body 10 and the right door body 20 separately, or to open the left door body 10 first and then the right door body 20, or to open the right door body 20 and then the left door body 10; thereby, it is achieved that the door opening method is not affected, and it is ensured that opening the refrigerator door on at least any one side can drive the flip beam body 30 to flip, without affecting the drawing and pulling of the drawer on the corresponding side, thereby improving the convenience of taking and putting food.

[0076] In the above embodiment, two groups of second guide shafts 32 can be provided at a set interval, and the two groups of second guide shafts 32 are adapted to different positions of the second arc-shaped guide grooves 51, so as to improve the smoothness of the second guide shafts 32 driving the flip beam body 30 to flip when moving along the second arc-shaped guide grooves 51. At the same time, in order to ensure that both groups of second guide shafts 32 can move to the fourth guide grooves 53 and exit the flip guide block 50 from the end of the fourth guide grooves 53, two groups of third arc-shaped guide grooves 52 are also provided, and the two groups of third arc-shaped guide grooves 52 are provided in parallel with each other.

[0077] like Figure 6 as well as Figures 10 to 14 As shown, the embodiment of the present application also provides a refrigerator, using the flip beam mechanism provided in the above embodiment. The refrigerator also includes a left door body 10 and a right door body 20 that are arranged to be opened and closed. The storage space corresponding to the left door body 10 is provided with a left drawer that can be pulled out, opened and closed, and the storage space corresponding to the right door body 20 is provided with a right door body 20 that can be pulled out, opened and closed. The flip beam body 30 is flipped and connected to the left door body 10 through the hinge 40, and the transmission guide rod 61 of the transmission assembly is arranged corresponding to the right door body 20. When opening and closing the left door body 10, the flip beam body 30 can be pulled through the hinge 40, and the flip beam body 30 is driven to flip by the cooperation of the second guide shaft 32 of the flip beam body 30 and the flip guide block 50. When opening and closing the right door body 20, the transmission guide rod 61, the transmission gear 62, the transmission stop rod 63 and the first guide shaft 631 can be used to act on the flip beam body 30, driving the flip beam body 30 to flip accordingly.

[0078] Furthermore, the second guide shaft 32 can be arranged at the top of the flip beam body 30, and the flip guide block 50 is fixed at the top of the refrigerator door frame at a position corresponding to the top of the flip beam body 30; the transmission assembly is arranged at the bottom of the refrigerator door frame at a position corresponding to the bottom of the flip beam body 30. The advantage of such a setting is that when the right door 20 is opened and the transmission guide rod 61 cannot be automatically popped out, it is convenient to manually pull out the transmission guide rod 61, which is convenient for controlling the flip beam body 30 to flip, and to pull out the right drawer and take in and put in items.
