Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 to 9 show a preferred embodiment of the present invention. In which fig. 1 to 7 show a hinge construction in one of the embodiments and fig. 8 to 9 show a hinge construction in another embodiment. Note that, for the sake of easy viewing, the upper door 10 and the lower door 20 in each of the drawings are partially illustrated. Specifically, a direction Z in fig. 1 is a vertical direction, a direction Y is a direction from the rear side of the refrigerator to the front side of the refrigerator, and a direction X is a direction from the right side of the refrigerator to the left side of the refrigerator when facing the refrigerator.
The embodiment provides a hinge structure arranged on a door body of a refrigerator, the refrigerator comprises an upper door body 10 and a lower door body 20 positioned below the upper door body 10, and the hinge structure is used for adjusting the height of the upper door body 10.
The hinge structure includes a supporter 100, a hinge shaft 200, and a transmission mechanism. The stay 100 is disposed between the upper door body 10 and the lower door body 20 (the vertical height of the stay 100 is lower than the upper door body 10 and higher than the lower door body 20, and the projection of the stay 100 in the horizontal plane may or may not coincide with the projection of the upper door body 10 or the lower door body 20 in the horizontal plane). The supporter 100 is fixed to a case of the refrigerator. Specifically, all exposed surface walls of the refrigerator without the door body can be referred to as a shell, that is, in the present application, an inner container and a cross beam inside the refrigerator can be referred to as a shell of the refrigerator.
In order to enable the supporting member 100 to bear a large pressure without occupying too much space, in one embodiment, the supporting member 100 may be connected to a cross beam of the refrigerator between the upper door body 10 and the lower door body 20. Specifically, the supporter 100 may have a plate shape and horizontally extend in a direction away from the refrigerator along an outer side surface of the cross beam. The support member 100 may also be integrally formed from the cross member, i.e., the support member 100 may be a laterally extending flange of the cross member.
The hinge shaft 200 is vertically arranged, and particularly, may be arranged perpendicular to a horizontal plane. The hinge shaft 200 includes three sections, and for convenience of description, the upper portion of the hinge shaft 200 is an upper shaft body 210, the middle portion thereof is a middle shaft body 220, and the lower portion thereof is a lower shaft body 230 after being referred to as a working position.
The hinge shaft 200 vertically passes through the supporter 100, and the middle shaft body 220 of the hinge shaft 200 is screw-coupled with the supporter 100, so that the hinge shaft 200 can change a vertical height by being rotated. Specifically, a screw thread may be disposed on the middle shaft body 220 of the hinge shaft 200, and a screw hole may be disposed on the supporter 100. When the hinge shaft 200 is rotated in the first direction M as shown in fig. 3 about an axis parallel to the length direction thereof, it ascends with respect to the supporter 100; when the hinge shaft 200 is rotated in a second direction (a direction opposite to the first direction M) about an axis parallel to a length direction thereof, it descends with respect to the supporter 100.
Since the upper shaft 210 of the hinge shaft 200 abuts against the bottom of the upper door 10, when the hinge shaft 200 rotates in the first direction M and rises, the upper shaft 210 abuts against the bottom of the upper door 10 of the refrigerator and lifts the upper door 10. When the hinge shaft 200 rotates in the second direction, the vertical height of the upper shaft body 210 is lowered, so that the vertical height of the upper door body 10 pressed against the upper shaft body 210 is also lowered. Therefore, the height of the upper door 10 of the refrigerator can be adjusted by driving the hinge shaft 200 to rotate.
In one embodiment, the lower shaft 230 of the hinge shaft 200 may extend downward into the lower door 20 of the refrigerator and allow the lower door 20 to rotate around the lower door, that is, the lower door 20 includes a hinge hole 21 at the top thereof, and the lower shaft 230 of the hinge shaft 200 extends downward through the hinge hole 21 into the lower door 20. The lower shaft 230 serves as a rotation shaft of the lower door 20, and the lower door 20 of the refrigerator rotates around the hinge shaft 200 during the door opening and closing processes of the lower door 20 of the refrigerator. Meanwhile, the hinge structure further comprises a transmission mechanism, and the transmission mechanism can be arranged in the lower door body 20 of the refrigerator. The transmission mechanism can drive the lower shaft 230 in the lower door 20 of the refrigerator to rotate after acquiring the driving force, and an operator can adjust the height of the upper door 10 of the refrigerator by driving the transmission mechanism in the lower door 20 of the refrigerator. The transmission mechanism is arranged in the lower door body 20 of the refrigerator, and the space in the lower door body 20 of the refrigerator is sufficient, so that the transmission mechanism is very convenient to arrange. Meanwhile, the size of the hinge shaft 200 is limited only by the thickness of the lower door body 20, so that the size thereof can be set to be large, and it is possible to transmit sufficient thrust. In addition, the transmission mechanism is arranged in the lower door body 20, so that the lower door body can be well protected, and faults are not easy to occur.
In another embodiment, the lower shaft 230 of the hinge shaft 200 and the transmission mechanism may not be disposed in the lower door body 20, the lower door body 20 has a separate rotation shaft, and a position of the lower door body 20 corresponding to the hinge structure is provided with a gap for accommodating the transmission mechanism. I.e., the hinge structure does not have any connecting structure with the lower door body 20.
When the lower shaft body 230 of the hinge shaft 200 and the transmission mechanism are disposed in the lower door body 20, the transmission mechanism may include a first bevel gear 310 and a second bevel gear 320 engaged with the first bevel gear 310. The first bevel gear 310 is connected to the lower shaft 230 and drives the lower shaft 230 to rotate. Specifically, the second bevel gear 320 includes a hub 311, the hub 311 is located above the gear teeth of the second bevel gear 320 in an operating state, and a bearing is sleeved on the hub 311, and the bearing can be in shaft hole fit with the hinge hole 21 of the lower door body 20, so that the lower door body 20 can freely rotate around the lower shaft body 230.
The second bevel gear 320 is engaged with the first bevel gear 310, so that the first bevel gear 310 can be rotated by driving the second bevel gear 320, thereby rotating the hinge shaft 200. The bevel gear can transmit larger torsion, so that the transmission mechanism can transmit larger torsion while transmitting smaller size by utilizing the bevel gear, and the space occupied by the transmission mechanism is reduced. Of course, in other embodiments, the transmission mechanism may also include a spur gear or a drive chain or other common transmission components.
To further reduce the available space occupied by the transmission, the first bevel gear 310 and the second bevel gear 320 may be arranged as shown in fig. 3. That is, the first bevel gear 310 is vertically arranged with its rotation axis after being connected to the lower shaft body 230, and the tooth surface of the first bevel gear 310 faces away from the middle shaft body 220 (the tooth surface of the first bevel gear 310 is inclined downward after being in the working position). The second bevel gear 320 is disposed below the first bevel gear 310 with its rotational axis arranged laterally. The vertical projection area of the hinged end of the lower door 20 of the refrigerator is not provided with other parts, so that the arrangement of the first bevel gear 310 and the second bevel gear 320 according to the above structure can reduce the possibility of position interference between the transmission mechanism and the internal elements of the lower door 20 of the refrigerator as much as possible.
The transmission mechanism is used for transmitting power, and the source of the power can be the driving motor 600 or manpower. When the power source is manual power, in one embodiment, a prism hole 321 may be provided at the center of the second bevel gear 320, and the prism hole 321 extends along the rotation axis of the second bevel gear 320. The prism hole 321 may be a regular hexagonal prism hole 321, and may be a through hole, a blind hole, or a counter sunk hole. The lower door body 20 is provided with an adjusting hole 22, the adjusting hole 22 faces the prism hole 321, so that the prism hole 321 of the second bevel gear 320 is exposed out of the door body, when the height of the upper door body 10 is adjusted, an operator can use an external tool to penetrate through the adjusting hole 22 and extend into the prism hole 321 of the second bevel gear 320, the external tool is driven to rotate to drive the second bevel gear 320 to rotate, and finally the hinge shaft 200 rotates.
In one embodiment, as shown in fig. 8 to 9, the power source of the transmission mechanism may also be a driving motor 600, and the driving motor 600 is connected to the second bevel gear 320 of the transmission mechanism for driving the second bevel gear 320 to rotate. In particular, since the second bevel gear 320 is positioned in the lower door body 20, when the height of the upper door body 10 does not need to be adjusted, the lower shaft body 230 of the hinge shaft 200 and the first bevel gear 310 do not move and the second bevel gear 320 rotates around the axis of the first bevel gear 310 during the opening and closing actions of the lower door body 20. Since second bevel gear 320 is meshed with first bevel gear 310, second bevel gear 320 will rotate about its own axis while rotating about the axis of first bevel gear 310 (it can be understood that second bevel gear 320 rotates while revolving around first bevel gear 310). On the contrary, if the second bevel gear 320 is connected to the driving motor 600, when the driving motor 600 drives the second bevel gear 320 to rotate, the door body will generate an opening and closing movement, and the premise that the driving motor 600 drives the door body to generate the opening and closing movement is that the lower shaft body 230 and the first bevel gear 310 are stationary.
As shown in fig. 3, when the driving motor 600 drives the second bevel gear 320 to rotate around its axis in the N direction, the second bevel gear 320 rotates around the axis of the first bevel gear 310 in the second direction (opposite to the first direction M), which drives the lower door 20 to rotate around the axis of the first bevel gear 310 in the second direction, and at this time, the lower door 20 moves towards the closing direction. When the driving motor 600 drives the second bevel gear 320 to rotate around the axis thereof in the opposite direction of the N direction, the second bevel gear 320 will rotate around the axis of the first bevel gear 310 in the first direction M, which will drive the lower door body 20 to rotate around the axis of the first bevel gear 310 together in the first direction M, and at this time, the lower door body 20 moves towards the opening direction. That is, after the driving motor 600 is connected to the second bevel gear 320, the driving motor 600 not only can drive the second bevel gear 320 to rotate the first bevel gear 310 (at this time, the position of the lower door 20 needs to be fixed, and the second bevel gear 320 cannot revolve around the first bevel gear 310), but also can drive the second bevel gear 320 to automatically open and close the lower door 20 (at this time, the driving force of the driving motor 600 needs to be not greater than a certain value, and the lower shaft 230 and the first bevel gear 310 need to be stationary). Particularly, an intelligent control module can be arranged in the refrigerator, and the driving motor 600 can automatically open and close the lower door body 20 of the refrigerator according to a door opening and closing signal transmitted by the intelligent control module, so that the intelligent control of the refrigerator is realized.
Because the front panel (the panel that deviates from the refrigerator inner bag) area of the door body is great, the error cost and the processing degree of difficulty of trompil on it are higher (once the trompil error is great during processing, whole front panel all scrapps). And the opening of the front panel may affect the integrity and aesthetic appearance of the refrigerator. In one embodiment, the adjusting hole 22 may be disposed on a side panel body of the lower door body 20, which is vertically arranged and perpendicular to the plane of the lower door body 20, and the rotation axis of the second bevel gear 320 is parallel to the plane of the lower door body 20. Because the side plate body of the lower door body 20 is in a long strip shape and has a small volume, the error cost during processing is low.
In a preferred embodiment, the adjusting hole 22 may also be disposed on the inner side plate of the lower door 20 facing the inner container of the refrigerator, where the rotation axis of the second bevel gear 320 is perpendicular to the door. The structure can ensure that the adjusting hole 22 is not exposed, better protects internal elements in the door body, prevents foreign matters from entering, and simultaneously ensures that the whole refrigerator is more attractive.
In order to prevent foreign matters from entering the lower door body 20 of the refrigerator, a protective plug 500 may be disposed on the adjusting hole 22 of the refrigerator, and the protective plug 500 may be detachably disposed on the adjusting hole 22. The protective plug 500 may be a flexible rubber material and covers the adjustment hole 22 by plugging. The protective plug 500 may be made of other hard materials and covers the adjustment hole 22 by means of screw coupling.
In one embodiment, only the upper end of the upper shaft 210 abuts against the upper door 10, and only the upper shaft is used for adjusting the height of the upper door 10. In another embodiment, the upper shaft 210 can also be used as a rotating shaft of the upper door 10, that is, the upper shaft 210 rotates during the opening and closing process of the upper door 10. Specifically, when the upper shaft 210 can be used as a rotating shaft of the upper door 10, the upper shaft 210 includes an extending column 211 and an abutting portion 212, the abutting portion 212 is disposed at a lower portion of a peripheral wall of the extending column 211, the extending column 211 extends upward from a bottom of the lower door 20 into the upper door 10, the abutting portion 212 abuts against a bottom of the lower door 20, and the extending column 211 is configured to enable the upper door 10 to rotate around a central axis thereof. The abutment portion 212 may be a projection on the peripheral wall of the extension column 211, and it may be annular and disposed around the circumference of the extension column 211. Further, the abutting portion 212 may be provided at a lower end portion of the upper shaft body 210, and when the abutting portion 212 abuts the supporter 100, the hinge shaft 200 is at a lower limit position with respect to the supporter 100. Of course, in other embodiments, a stopper may be further provided at an upper portion of the middle shaft body 220 such that the stopper defines a lower limit position of the hinge shaft 200 with respect to the supporter 100. Similarly, the blocking member may be a protrusion on the peripheral wall of the middle shaft body 220, and the blocking member may also be annular and arranged around the circumference of the middle shaft body 220.
In one embodiment, the hinge structure may further include a protective sleeve 400. The protective cover 400 is arranged in the lower door body 20, and the transmission mechanism is arranged in the protective cover 400 and positioned on the protective cover 400. During the assembly, can assemble earlier drive mechanism and form a whole back on lag 400, set up lag 400 again with the door body of refrigerator in, this kind of assembly mode can make the structure of first conical gear 310 and second conical gear 320 among the drive mechanism more stable on the one hand, on the other hand also can let drive mechanism's wholeness stronger, make drive mechanism can become an optional part of door body 20 under the refrigerator, when need set up different drive mechanism in the door body 20 down, only need change drive mechanism and lag 400 with drive mechanism constitute whole can, the door body 20 down need not set up complicated mounting structure, the manufacturing of door body 20 down has been made things convenient for.
