It should be noted that the embodiment of the present invention is only described by taking the shelf assembly of the refrigerator as an example. It should be understood that the shelf assembly is not limited to use in a refrigerator, but may be used in any application requiring similar applications, such as in a sales counter, a snack cabinet, or even a display cabinet.

Referring to fig. 1 to 6, according to an embodiment of the present invention, a shelf assembly is provided, including a shelf 2 and a first link 14. Wherein, a first limit piece and a driving piece are arranged on the shelf 2. The first end of the first connecting rod 14 is hinged to the shelf 2, the second end of the first connecting rod 14 is used for being hinged to a component to be installed, and the first end of the first connecting rod 14 is provided with a second limiting part. The first limiting member and the second limiting member can form a limiting fit therebetween, so as to prevent the first link 14 from rotating, and the first link 14 is fixed in a current state. In addition, the relationship between the first limiting part and the second limiting part is controlled by the driving part. Specifically, the driving member controls the first limiting member to switch between a position where the first limiting member is in limiting fit with or separated from the second limiting member, the first connecting rod 14 is fixed at the limiting fit position, and the first connecting rod 14 freely rotates around a hinge point of the second end as a rotation center at the separation position.

In the shelf assembly of the embodiment of the invention, in a natural state, the first limiting piece and the second limiting piece form a limiting and matching relationship, and the first limiting piece is arranged on the shelf 2, the second limiting piece is arranged on the first connecting rod 14, so that the first limiting piece and the second limiting piece are matched, the position relationship between the lower shelf 2 and the first connecting rod 14 can be locked, and the bearing effect of the shelf 2 is ensured. On this basis, the driving member can control the first limiting member and the second limiting member to be disengaged, so that the locking relationship between the shelf 2 and the first connecting rod 14 is released, and the shelf 2 can be dragged to any height within the movable range of the first connecting rod 14. The shelf component is more flexible in space division and can adapt to different requirements of different crowds.

Wherein, through the height of adjusting shelf 2, can solve the too big problem that leads to the space extravagant of shelf 2 top or below space height, also can solve the unable problem of placing high-size article of shelf 2 top or below space height undersize. In addition, if the current shelf assembly is higher in height, the storage and the taking of the articles on the shelf 2 can be met by lowering the position of the shelf 2 in the shelf assembly.

When only the first link 14 is provided, since the shelf 2 is fixed to the member to be mounted only by the first link 14, the requirement for the structural strength of the first link 14 is high, and the range in which the shelf 2 can bear load is limited. Based on this, the shelf assembly of the embodiment of the invention further comprises a second connecting rod 15, wherein a third end of the second connecting rod 15 is hinged to the shelf board 2, and a fourth end of the second connecting rod 15 is used for being hinged with a component to be installed. Thereby, the shelf 2 rotates around the member to be mounted with the first link 14 and the second link 15 as the rotation shafts at the time of position adjustment.

The "third end" and the "fourth end" refer to the two ends of the second link 15, and their names are only for distinguishing from the "first end" and the "second end" of the first link 14.

It should be noted that, when the shelf assembly includes the first connecting rod 14 and the second connecting rod 15, since one end of the first connecting rod 14 and one end of the second connecting rod 15 are both connected to the shelf 2, and the other end of the first connecting rod 14 and the other end of the second connecting rod 15 are both connected to the component to be mounted, the portion of the shelf 2 connected between the first connecting rod 14 and the second connecting rod 15 can be regarded as one connecting rod, and the portion of the component to be mounted connected between the first connecting rod 14 and the second connecting rod 15 can be regarded as one connecting rod, so that the four-bar mechanism can be regarded as being formed between the whole shelf assembly and the component to be mounted. The installation stability of the shelf 2 can be ensured by the four-bar linkage.

Further, the first connecting rod 14 is parallel to the second connecting rod 15, and the shelf 2 is horizontally installed at the first end of the first connecting rod 14 and the third end of the second connecting rod 15, so that the support of the shelf 2 can be ensured, the shelf 2 has sufficient bearing capacity, and the shelf 2 is horizontally installed between the first connecting rod 14 and the second connecting rod 15, so that the articles can be ensured to be placed on the shelf 2. Of course, the installation angle of the shelf 2 may be adjusted as needed. For example, when the shelf 2 is not a plane plate but a structure with an inclination angle for placing red wine, the shelf 2 may also be arranged at an inclination angle with respect to the horizontal plane in order to facilitate the placement of red wine.

According to one embodiment of the present invention, the first connecting rod 14 is located below the second connecting rod 15, that is, the first limiting member and the second limiting member directly control whether the connecting rod located below is locked or not. Moreover, the first end of the first link 14 is located at the front side of the third end of the second link 15 (taking a refrigerator as an example, the side close to the refrigerator door is the front side, and vice versa; in the same way, the directions indicated by "front side" and "rear side" in the same situation are the same as those in the above), so that the first limiting member, the second limiting member and even the driving member are further located closer to the front side, which is convenient for operation. Of course, the first end of the first link 14 may be located behind the third end of the second link 15, or the first link 14 may be located above the second link 15. Specifically, it is sufficient to form a four-bar linkage between the shelf 2 and the member to be mounted, and no particular requirement is imposed on the positional relationship between the first link and the second link among the four-bar linkages.

Referring to fig. 1 to 5, according to one embodiment of the present invention, the shelf 2 includes a shelf body 22 and first mounting plates 23 disposed on two sides of the shelf body 22, wherein the first limiting members and the driving members are disposed on the first mounting plates 23. In the refrigerator, the shelf assembly of the refrigerator is taken as an example, the left and right sides of the shelf body corresponding to the shelf body are indicated by the two sides of the shelf body 22 (the left and right sides are judged by a user of the refrigerator, and the same directions are indicated by the left and right sides in the same situation). The first mounting plates 23 are arranged on the left side and the right side of the shelf body 22, so that the arrangement of the first limiting part and the driving part can be facilitated. Of course, the first limiting member and the driving member may be directly disposed on the left and right side walls of the shelf 2 without disposing the first mounting plate 23, and only limited by the thickness of the shelf 2, and the direct mounting of the first limiting member and the driving member is relatively difficult.

The first mounting plate 23 is at a first setting angle with the horizontal plane, for example, the first setting angle is ninety degrees, and then the first mounting plate 23 is located in the vertical plane. On this basis, the first end of the first link 14 and the third end of the second link 15 are both hinged to the first mounting plate 23. It should be noted that the first set angle can be other angles greater than zero and less than ninety degrees to facilitate the assembly of the first and

second links

14 and 15.

In one embodiment, the first connecting rod 14 and the second connecting rod 15 are symmetrically arranged on both sides of the shelf 2, so as to ensure that the shelf 2 is stressed in a balanced manner.

According to one embodiment of the invention, the rear side of the shelf 2 is provided with a first embedding part, and the front side of the part to be mounted is provided with a second embedding part matched with the first embedding part; a linear guide assembly extending back and forth is provided between the shelf body 22 and the first mounting plate 23 for switching the shelf 2 between positions abutting and disengaging the rear wall 3, with the first and second inlays in abutting position.

The expression "a linear guide assembly extending back and forth is provided between the shelf body 22 and the first mounting plate 23" means that the shelf body 22 and the first mounting plate 23 can move linearly relative to each other along the straight guide assembly. The first mounting plate 23 does not move back and forth, so that the shelf body 22 can be close to or far away from the component to be mounted only by adjusting the linear motion of the shelf body 22 relative to the first mounting plate 23 in the front and back direction, and the shelf 2 is switched between the positions of abutting against and separating from the component to be mounted. The cooperation is inlayed to the first portion of inlaying and the second in the butt position, and then can make shelf 2 inseparabler with treat the installation component complex, guarantees shelf 2's installation reliability. When the position of the shelf 2 needs to be adjusted, the shelf body 22 is pulled out forwards, and the first embedding part and the second embedding part are separated from each other.

The first embedding part and the second embedding part can adopt any structural form on the premise of meeting the matching relation. For example, when the first embedding portion is the embedding gap 211, the second embedding portion is a protrusion structure matching with the first embedding portion; when the first embedding part is step-shaped, the second embedding part is matched with the first embedding part in step-shaped; when the first insert part is a serration, the second insert part is a matching serration, and so on, this is not exhaustive.

Wherein, the edge of the shelf body 22 can be provided with the edge-covering decorative strip 21, and the embedding gap 211 can be formed on the edge-covering decorative strip 21.

According to one embodiment of the present invention, the linear guide assembly includes a slide groove 212 and a slide rail 231 which are engaged with each other, and one of the shelf body 22 and the first mounting plate 23 is provided with the slide groove 212 and the other is provided with the slide rail 231. Through the cooperation between the slide groove 212 and the slide rail 231, the shelf body 22 can be prevented from shaking left and right in the middle of moving in the front-rear direction.

It should be understood that the linear guide assembly is not limited to the examples shown herein, and may be any linear guide structure disclosed in the prior art and may be implemented, for example, in the form of a guide rod plus a guide sleeve.

It is worth mentioning that the arrangement of the sliding groove 212 and the sliding rail 231 can also facilitate the replacement of the shelf 2. The size of the present shelf 2 is very close to the size of the cross section of the refrigerator compartment, but it is also possible to replace shelves 2 of different sizes, thereby satisfying a more flexible adjustment of the compartment interior space. For example, the size of the shelf 2 in the front-rear direction of the refrigerator may be reduced by one third to one half from the current size.

Referring to fig. 2, 4 and 5, the slide groove 212 is provided on the shelf body 22, and the slide rail 231 is provided on the first mounting plate 23. The sliding groove 212 is relatively easy to process on the shelf body 22, and the sliding groove 212 does not affect the structural strength of the shelf body 22. Further, the slide groove 212 may be provided on the hemming molding 21. In addition, it is relatively easy to form the slide rail 231 on the first mounting plate 23 during the process. Further, the slide rail 231 is arranged at the top of the first mounting plate 23, and then after the shelf body 22 and the first mounting plate 23 are assembled, the first mounting plate 23 is positioned below the shelf body 22, so that the appearance of the shelf 2 is not affected. Of course, the slide rail 231 may be disposed at the bottom of the first mounting plate 23 or at any other position. The chute 212 may be provided in the first mounting plate 23, and the slide rail 231 may be provided in the shelf main body 22.

In one case, the sliding groove 212 is a T-shaped groove, and the sliding rail 231 can only enter through the end of the T-shaped groove, so that the reliability of the assembly between the shelf body 22 and the first mounting plate 23 is ensured. The "T-shaped groove" refers to the T-shaped cross section of the sliding groove 212. Of course, the form of the sliding slot 212 is not limited by the examples herein, for example, the sliding slot 212 may also be a U-shaped slot or any other form of slot. The cross-sectional shape of the guide rail can be adapted to the cross-sectional shape of the sliding groove 212 to satisfy the fitting relationship therebetween.

It should be noted that the slide rail 231 may be replaced by a slide block, but because the slide rail 231 has a larger size, it has a larger assembly area with the slide groove 212 than the slide block, and thus the force-bearing area between the shelf body 22 and the first mounting plate 23 may be increased, and the reliability of the assembly between the shelf body 22 and the first mounting plate 23 may be ensured.

Referring to fig. 1 to 5 again, the first limiting member is a pawl 13, the second limiting member is a ratchet 16, and the ratchet 16 and the first link 14 are fixed and cannot move relatively. And then through the cooperation between the pawl 13 and the ratchet wheel 16, locking between the relative positions of the shelf 2 and the first connecting rod 14 is realized, and the first connecting rod 14 is prevented from rotating relative to the shelf 2, so that the shelf 2 is locked at the current position. When the position of the shelf 2 needs to be adjusted, the pawl 13 is separated from the ratchet wheel 16 through the driving piece, and then the position between the shelf 2 and the first connecting rod 14 can be freely adjusted, so that the shelf 2 can be suspended to any height position, and then the flexible division of the internal space of the refrigerator can be realized, and different use requirements of different users are met.

Referring to fig. 2, 3 and 5, the pawl 13 includes a working end 132 and a mounting end, and the driving member includes a multi-tooth member, a gear shaft 11 and a push button 9. The multi-tooth component is arranged at the mounting end of the pawl 13, the multi-tooth component is arranged at the mounting end and is equivalent to the pawl 13, the gear shaft 11 is matched with the multi-tooth component, and the gear shaft 11 is rotatably connected to the first mounting plate 23 through the torsion spring 10; the button 9 is in transmission connection with the multi-tooth component through the gear shaft 11, the button 9 is switched between a natural state and a stressed state, and the button 9 drives the working end 132 to be separated from the ratchet 16 under the stressed state.

Specifically, in a natural state, the button 9 is not subjected to an external force, and the working end 132 of the pawl 13 and the ratchet wheel 16 are in a limit matching position, that is, the positions between the pawl 13 and the ratchet wheel 16 are locked, so that the first connecting rod 14 cannot rotate relative to the shelf 2, and the shelf 2 is locked at the current position. Under the stress state, the button 9 is subjected to the action of external force, the movement is transmitted to the multi-tooth component through the gear shaft 11, the multi-tooth component is arranged at the mounting end of the pawl 13, the movement of the multi-tooth component further causes the movement of the pawl 13, and finally the working end 132 of the pawl 13 is separated from the ratchet wheel 16, at the moment, the locking relation between the first connecting rod 14 and the shelf 2 is released, the first connecting rod 14 can freely rotate, and the shelf 2 can rotate to any angle by taking the first connecting rod 14 as a rotating shaft, so that the position adjustment of the shelf 2 is realized. Wherein the shelf 2 is directly moved to the lowermost position under power when the bracket is held prior to finger operation of the button 9 to prevent unlocking of the position between the first link 14 and the shelf 2.

Wherein the multi-tooth member may take the form of, but is not limited to, a rack, a pinion 131, or other member comprising a plurality of teeth. In fig. 2, 3 and 5, the multi-tooth component is in the form of a gear 131, and at this time, the gear shaft 11 drives the gear 131 to rotate, so that the mounting end swings, and the working end 132 of the pawl 13 is locked or disengaged from the ratchet wheel 16 during swinging.

In one embodiment, the gear 131 is integrally formed at the mounting end of the pawl 13, and the mounting end is hinged to the first mounting plate 23, and the pawl 13 is driven to swing by the rotation of the gear shaft 11 due to the meshing of the gear 131 and the gear shaft 11. Of course, the gear 131 does not have to be integrally formed at the mounting end of the pawl 13, as long as it can drive the pawl 13 to move and lock or unlock the ratchet 16. Further, the multi-tooth component in the form of gear 131 need not be a complete gear 131, but may be only a partial gear 131.

When the multi-tooth component is a rack, the gear shaft 11 drives the rack to do linear motion, so that the working end 132 of the pawl 13 does linear motion, and the working end 132 of the pawl 13 is locked or disengaged from the ratchet wheel 16 in the process of linear motion.

In fig. 5, a cross-shaped hole 901 is formed in the button 9, and the cross-section of one end of the gear shaft 11 is also cross-shaped, so that one end of the gear shaft 11 is mounted in the cross-shaped hole 901 of the button 9, and the gear shaft 11 is driven to rotate by pressing the button 9. Rotation of the gear shaft 11 causes the gear 131 to rotate, which in turn causes the working end 132 of the pawl 13 to swing such that the working end 132 disengages the ratchet wheel 16. As the gear shaft 11 is connected with the first mounting plate 23 through the torsion spring 10, the torsion spring 10 is forced to deform during the rotation of the gear shaft 11. Once the button 9 is released, the gear shaft 11 rotates the gear 131 under the restoring force of the torsion spring 10, so that the pawl 13 and the ratchet 16 are locked.

In one embodiment, the spring body of the torsion spring 10 is sleeved on the gear shaft 11, one arm of the torsion spring 10 is fixed with the button 9, and the other arm of the torsion spring 10 is fixed with the first mounting plate 23.

The button 9 and the gear shaft 11 are not necessarily connected through the cross-shaped hole 901, but may be connected through any other rotation-stopping hole, and may be bonded, welded, or screwed. When the rotation stopping hole is adopted for connection, the button 9 and the gear shaft 11 are convenient to disassemble and assemble.

As can be seen from fig. 2, 3 and 5, the gear portion of the gear shaft 11, the pawl 13 and the ratchet wheel 16 are all located outside the first mounting plate 23, and these components are shielded by the first mounting plate 23 and cannot be seen from the outside, thereby ensuring the aesthetic appearance of the refrigerator.
