The embodiment of the utility model provides a storage device can be for freezing cold storage devices such as refrigerator, freezer, show cupboard, still can be for article storage cabinet etc. do not have the storage device of cold-stored freezing function and need adjustment shelf position.

The principle of the storage device of the present invention will be described below by taking a refrigerator as an example, and the structure of other storage devices can be specifically set with reference to the structure in the embodiment of the refrigerator.

Fig. 1 is a perspective view of a specific embodiment of a refrigerator according to the present invention, and as shown in fig. 1, the refrigerator according to the embodiment of the present invention has an approximately rectangular parallelepiped shape. The appearance of the refrigerator is defined by a storage chamber 1 defining a storage space and a plurality of door bodies 2 protruding into the storage chamber 1;

as shown in fig. 1, the storage chamber 1 has an open cabinet, the storage chamber 1 is vertically partitioned into a lower freezing chamber 12 and an upper refrigerating chamber 11, and each of the partitioned spaces may have an independent storage space.

In detail, the freezing chamber 12 is defined at a lower side of the storage chamber 1 to be selectively covered by a drawer type freezing chamber door 21. The refrigerating compartment 11 may be selectively opened or closed by a refrigerating compartment door body 22 pivotably mounted on the refrigerating compartment 11.

As shown in fig. 2 and 3, the refrigerator further includes a shelf 3 and a driving device 4, the shelf 3 is movably disposed in the storage room 1 (for example, the refrigerating room 11), the driving device 4 includes a driving unit 41, a moving member 42 and a pulling rope 43, the moving member 42 is connected to the shelf 3 through the pulling rope 43, the driving unit 41 is configured to drive the moving member 42 to move relative to the wall of the storage room 1 so as to pull the shelf 3 to move relative to the wall of the storage room 1 along a first direction H through the pulling rope 43, and the first direction H is a height direction of the storage room 1.

In the refrigerator, as shown in fig. 2 and 3, since the moving member 42 is connected to the shelves 3 through the pulling rope 43, when a user needs to adjust the position of the shelves 3, the driving unit 41 can drive the moving member 42 to move relative to the chamber wall of the storage chamber 1, so as to pull the shelves 3 to move relative to the chamber wall of the storage chamber 1 along the first direction H through the pulling rope 43, thereby adjusting the shelves 3 to an optimal position, which not only facilitates the user to place articles with different heights in the storage chamber 1, so as to improve the utilization rate of the space in the storage chamber 1, but also eliminates the shelves 3 and the articles thereon when the user adjusts the position of the shelves 3, thereby greatly facilitating the use of the user and improving the user experience; meanwhile, in the refrigerator, the shelves 3 move along the first direction H in a pulling manner of the pulling rope 43, and compared with a driving manner in which the nut screw directly drives the shelves 3 to move, the length of the pulling rope 43 can be adjusted according to actual conditions, so that the driving unit 41 can pull the shelves 3 to move at a position far away from the shelves 3 through the pulling rope 43, the setting position of the driving unit 41 can be widened, and the driving unit 41 can be conveniently installed.

In the above embodiment, the moving direction of the driving unit 41 driving the moving member 42 is not unique, for example, the moving direction of the moving member 42 may be different from the moving direction of the layer frame 3: as shown in fig. 3 and 4, the driving unit 41 is used for driving the moving member 42 to move along a second direction X relative to the chamber wall of the storage chamber 1, the second direction X being a width direction of the storage chamber 1; the driving device 4 further comprises a first reel 44 disposed on the wall of the storage room 1, the first reel 44 and the moving member 42 are located on the same side of the shelf 3 and are arranged along the second direction X, and the middle portion of the pulling rope 43 is wound on the first reel 44 to change the force transmission direction of the pulling rope 43.

In addition, the moving direction of the moving member 42 may also be the same as the moving direction of the shelves 3: as shown in fig. 9, the driving unit 41 (e.g., a lead screw motor) is used to drive the moving member 42 (e.g., a lead screw of the lead screw motor) to move in the first direction H relative to the wall of the storage chamber 1. Compared with the embodiment that the moving direction is the same as the moving direction of the shelves 3, and the moving direction of the moving member 42 is different from the moving direction of the shelves 3, as shown in fig. 2 and 3, the middle part of the pulling rope 43 is wound on the first reel 44 to change the pulling direction, so that the moving direction of the moving member 42 is perpendicular to the moving direction of the shelves 3, and the moving direction of the moving member 42 is perpendicular to the moving direction of the shelves 3, so that the storage chamber 1 does not need to be provided with more space in the first direction H to avoid the moving member 42 to move, the size of the storage chamber 1 in the first direction H can be reduced, and the height of the refrigerator can be prevented from being too high.

It should be noted that: as shown in fig. 1 and 2, the width direction X of the storage chamber 1 is a direction perpendicular to both the height direction H and the depth direction Y of the storage chamber 1; the depth direction Y of the storage chamber 1 is a direction parallel to the thickness direction of the door of the storage chamber 1 when the door is closed.

In order to increase the moving distance of the traction rope 43 for pulling the layer rack 3 in the first direction H, as shown in fig. 2 and 3, the driving device 4 further includes a second reel 45 and a connecting seat 46 (which may be a connecting column, for example) both disposed on the chamber wall of the storage chamber 1, the second reel 45, the connecting seat 46 and the first reel 44 are located on the same side of the layer rack 3, the second reel 45 is connected with the moving member 42 and is fixed relative to the position of the moving member 42, one end of the traction rope 43 is connected with the connecting seat 46, the other end is connected with the layer rack 3, and the middle portion is wound around the first reel 44 and the second reel 45, when the moving member 42 moves relative to the chamber wall of the storage chamber 1 in the second direction X, the second reel 45 can pull the traction rope 43, so that the layer rack 3 moves relative to the chamber wall of the storage chamber 1. Through the above arrangement, when the moving member 42 moves in the second direction X by the distance d, the moving distance of the pulling rope 43 is 2d, that is, the moving distance of the shelf 3 in the first direction H is 2d, so that when the moving member 42 moves by a certain distance, the moving distance of the shelf 3 can be greatly increased, and the range of position adjustment of the shelf 3 can be enlarged.

The positional relationship among the coupling boss 46, the first reel 44, and the second reel 45 is not unique, and for example, as shown in fig. 3, the coupling boss 46, the first reel 44, and the second reel 45 may be located on the same side of the second reel 45 in the second direction X. In addition, as shown in fig. 8, the coupling seat 46 and the first reel 44 may be located on both sides of the second reel 45 in the second direction X. Compared with the connecting seat 46 and the first reel 44 which are respectively positioned on two sides of the second reel 45, when the connecting seat 46 and the first reel 44 are positioned on the same side of the second reel 45, when the moving piece 42 moves along the second direction X and in the direction far away from the first reel 44, the layer frame 3 can be immediately driven to move along the first direction H through the pulling rope 43, and the idle stroke of the moving piece 42 is effectively reduced.

In order to reduce the friction force applied to the pulling rope 43 during the movement of the pulling layer rack 3, as shown in fig. 2 and 3, a first reel 44 is rotatably provided on the wall of the storage room 1, and a second reel 45 is rotatably connected to the moving member 42. With the above arrangement, the first and second reels 44, 45 can be rotated to reduce friction with the pulling rope 43 during movement of the pulling truck 43 in the pulling truck 3, so that the driving efficiency of the driving device 4 can be improved.

In addition to the above arrangement, the first reel 44 may be fixedly provided on the compartment wall of the storage compartment 1, and the second reel 45 may be rotatably connected to the moving member 42; the first reel 44 may be rotatably provided on the wall of the storage chamber 1, and the second reel 45 may be fixedly connected to the moving member 42. This also has the effect of reducing the friction to which the pulling rope 43 is subjected during movement of the pulling trestle 3.

In the refrigerator, the position layout of the moving member 42 and the shelves 3 is not unique, for example, as shown in fig. 2 and 3, the moving member 42 may be positioned at an upper side of the shelves 3. When a user needs to adjust the position of the shelves 3 upwards, the driving unit 41 drives the moving member 42 to move along the second direction X and towards the wall of one side of the storage room 1, and the pulling rope 43 is tensioned and pulls the shelves 3 to move upwards; when the user needs to adjust the position of the shelves 3 downwards, the driving unit 41 drives the moving member 42 to move along the second direction X and towards the other side chamber wall of the storage chamber 1, the pulling rope 43 is released at this time, and the shelves 3 move downwards under the action of their gravity.

In addition, as shown in fig. 10, the moving member 42 may also be located at the lower side of the layer frame 3, and the upper side of the layer frame 3 is provided with an elastic member 6 (such as a spring), and the elastic member 6 is connected with the chamber wall of the storage chamber 1 and the layer frame 3; when a user needs to adjust the position of the shelves 3 downwards, the driving unit 41 drives the moving member 42 to move along the second direction X and towards a side chamber wall of the storage chamber 1, the pulling rope 43 is tensioned and pulls the shelves 3 to move upwards, and meanwhile, the elastic member 6 is elastically deformed to provide an upward elastic force to the shelves 3; when the user needs to adjust the position of the shelves 3 upwards, the driving unit 41 drives the moving member 42 to move along the second direction X and towards the other side chamber wall of the storage chamber 1, the pulling rope 43 is released at this time, and the shelves 3 move upwards under the elastic force of the elastic member 6. Compared with the moving member 42 arranged at the lower side of the shelf 3, when the moving member 42 is arranged at the upper side of the shelf 3, as shown in fig. 2 and 3, the structure of the driving unit 41 is simpler, the elastic member 6 is not required to be arranged, and meanwhile, heavier objects can be placed on the shelf 3 (when the moving member 42 is arranged at the lower side of the shelf 3, the elastic force of the elastic member 6 needs to drive the shelf 3 to ascend, and the weight of the objects placed on the shelf 3 is limited due to the limited elastic force of the elastic member 6).

In the refrigerator, the installation positions of the driving unit 41 and the moving member 42 are not unique, and for example, as shown in fig. 2 and 3, the driving unit 41 and the moving member 42 are both installed in the storage chamber 1 and on the rear chamber wall 13 of the storage chamber 1; the rear chamber wall 13 of the storage chamber 1 is a chamber wall of the storage chamber 1 opposite to the opening of the storage chamber 1. Further, the following may be mentioned: the driving unit 41 and the moving member 42 are both disposed inside the storage chamber 1 and on a top chamber wall of the storage chamber 1. Compare drive unit 41 and moving member 42 and all set up on the top locular wall of storeroom 1, when drive unit 41 and moving member 42 all set up on the back locular wall 13 of storeroom 1, can avoid drive unit 41 and moving member 42 to the occupation of storeroom 1 inner space on first direction H like this, this article and drive unit 41, moving member 42 interfere with when having avoided placing higher article in the storeroom 1 to guarantee the normal placement of storeroom 1 article.

In addition to the above arrangement, the driving unit 41 and the moving member 42 may be disposed outside the storage room 1, for example, on the upper surface of the storage room 1, an escape through hole is opened on the wall of the storage room 1, and the pulling rope 43 extends out of the storage room 1 from the escape through hole and is connected to the moving member 42. Compared with the arrangement outside the storeroom 1, when the driving unit 41 and the moving member 42 are arranged inside the storeroom 1, the installation is easier, avoiding through holes do not need to be formed in the wall of the storeroom 1, and the cold quantity in the storeroom 1 is prevented from being leaked to the outside from the avoiding through holes.

In order to make the lifting process of the shelf 3 more stable, as shown in fig. 2 and 3, the number of the pulling ropes 43 is two, the number of the moving members 42 is two, and the two moving members 42 are respectively connected with two end portions of the shelf 3 along the second direction X through the corresponding pulling ropes 43 in a one-to-one correspondence manner; the driving unit 41 is used for driving the two moving members 42 to move synchronously relative to the chamber wall of the storage chamber 1 so as to pull the shelves 3 to move relative to the chamber wall of the storage chamber 1 along the first direction H by the two pulling ropes 43. Through setting up two moving members 42, two tractive lines 43 to two tractive lines 43 are connected with layer frame 3 along two tip one-to-one of second direction X respectively, like this at the in-process that layer frame 3 goes up and down, just can make layer frame 3 keep balance on second direction X, avoid appearing rocking, thereby make the process that layer frame 3 goes up and down more steady, and then be favorable to guaranteeing that the article on layer frame 3 can not drop or empty.
