Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in fig. 1, 2 and 3, the present invention provides an embodiment of a drawer box capable of being opened and lifted quickly, the drawer box includes: drawer box body, elevating system. The drawer box body is formed by connecting a front section box body and a rear section flexible elastic frame, and the rear section flexible elastic frame can elastically deform and contract downwards relative to the front section box body. In this embodiment, the front box body is a wedge-shaped box 5 with a high front part and a low back part, as shown in fig. 2, that is, the left side (front) of the wedge-shaped box 5 is high, the right side (back) is low, and the flexible elastic frame is a wedge-shaped flexible elastic frame 4 with a high front bottom and a high back part, as shown in fig. 3, the left side (front) of the wedge-shaped flexible elastic frame 4 is low, the right side (back) is high, and the front end of the wedge-shaped flexible elastic frame 4 and the upper part of the front end of the wedge-shaped box 5 are hinged 41 to form a drawer box body with a complete rectangular main body. When downward pressure is applied to the wedge-shaped flexible elastic frame 4, the wedge-shaped flexible elastic frame 4 is elastically deformed and contracted downward, and simultaneously rotates around the hinge shaft 41 clockwise. The elevating system in this embodiment includes: the screw nuts 51 respectively arranged at four corners of the wedge-shaped box 5 can use a nut sleeve structure, the screw 8 matched with the screw nuts 51 for transmission, a transmission mechanism for driving the screw 8 to rotate and a driving motor mechanism. The transmission mechanism includes: the belt wheel 13 and the screw gear 7 which are coaxially arranged with the lower end of one of the four screw rods 8, the belt wheel 13 which is coaxially arranged with the lower end of the other three screw rods 8, and the four belt wheels 13 have the same diameter and are used for a belt 9 for belt transmission of the belt wheel 13. The driving motor mechanism comprises a motor 6 and a motor gear 11 coaxially mounted with a shaft of the motor, and the motor gear 11 is in meshing transmission with the lead screw gear 7. According to the requirement, the transmission mechanism can also adopt other transmission mechanisms, for example, a gear set is meshed for transmission to drive the screw rod nut mechanism for transmission, and a belt transmission mechanism can also be selected, namely, a driven belt wheel of the belt transmission mechanism and the lower end of the screw rod are coaxially arranged, and the diameters of the driven belt wheels are the same. The driving motor mechanism comprises a motor and a driving belt wheel coaxially mounted with a shaft of the motor, and two sides of the driving belt wheel are respectively provided with a tensioning wheel so as to increase the friction force of the belt. The driving belt wheel drives the driven belt wheel of the transmission mechanism so as to drive the screw rod to rotate. In this embodiment, all the belt drives can adopt synchronous belt drive to ensure the reliability of the belt drive.

As shown in fig. 1, the present invention further provides a refrigerator, which comprises a compartment 1 and a drawer 10. The drawer box is arranged in the drawer 10, and the top surface in the box chamber 1 is provided with the restraint wheels 3 corresponding to the left side and the right side of the wedge-shaped flexible elastic frame 4. A top plate 2 is fixedly hoisted on the top surface inside the box chamber 1 through four limit switches 12 which are uniformly distributed (as shown in figure 5).

As shown in fig. 4 and 5, the lifting mechanism and the drawer of the drawer box of the present invention can be controlled by the controller of the refrigerator. When the drawer lifting device is used, after a user sends an instruction for opening the drawer 10 to the controller, the controller controls the horizontal driving mechanism of the drawer 10 to drive the drawer 10 to move outwards along the guide rails, and simultaneously the controller controls the driving motor 6 of the drawer box to rotate and drives the lifting mechanism to lift the drawer box upwards. Because the utility model discloses make the latter half 4 of drawer box into the framework that can downward elastic deformation, also upward movement when the drawer box outwards removed, after the take the altitude, the front end on the 4 left and right sides limit of wedge flexible elasticity frame just contacts with the restraint wheel 3 of locating the 1 inside top surfaces of box room. At this time, the drawn part of the drawer box continues to rise, the wedge-shaped flexible elastic frame 4 which is not drawn out is pressed by the constraint wheel 3 to elastically deform and contract downwards, and simultaneously, the wedge-shaped flexible elastic frame is clockwise transmitted around the hinge shaft 41 of the drawer box and is folded towards the limiting point 42 at the lower part. As shown in fig. 5, after the drawer box is completely and transversely pulled out of the box compartment 1, the restraining wheel 3 is disengaged from the wedge-shaped flexible elastic frame 4, and the wedge-shaped flexible elastic frame 4 rapidly rebounds upwards to restore the original shape.

The utility model provides a refrigerator can take out the drawer box and go on simultaneously with two processes that rise, has reduced the user and has got the latency of putting article, has improved the efficiency of taking article, has promoted user's use and has experienced.

Because roof 2 has been hoisted through limit switch 12 in the top in refrigerator compartment 1, the drawer box constantly rises, when roof 2 receives in the drawer box the article that is higher than the drawer box port extrusion from bottom to top, will trigger the limit switch 12 at top, just control motor 6 stall after the controller detects this limit switch 12's signal, the drawer box stops to rise to article in the extrusion drawer box are avoided. If the drawer box is empty or not full, the lateral pull-out and vertical upward movement can be continued.

Finally, before the drawer 10 is retracted into the compartment 1, the controller controls the motor 6 to rotate reversely to drive the drawer box to descend until the drawer box is fully retracted into the external drawer 10, and then the controller controls the horizontal driving mechanism of the drawer 10 to drive the drawer to be retracted into the compartment 1.

The above description is only an embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
