Detailed Description
The invention is described in further detail below with reference to the embodiments of the drawings.
Example 1
As shown in fig. 1 to 2, the liftable drawer includes:
a drawer body 1 for holding articles;
the drawer frame 2 is the installation foundation of the drawer 1;
four guide rails 3 are arranged on the inner walls of the two sides of the drawer frame 2 in parallel up and down, and two guide rails are arranged on each side.
A driving device 4 for driving the connecting mechanism 5 to reciprocate relative to the guide rail, comprising a motor 41, which is arranged between the top wall of the drawer frame and a housing (not shown in the figure), wherein the motor 41 is a gear motor in the embodiment, and the motor 41 drives the connecting wire disc 42; one end of the pull cord 43 is wound on the wire coil 42, and the middle of the pull cord 43 is supported on a plurality of pulleys 44 to reduce the pull cord friction. The present embodiment provides the motor 41 and the wire coil 42 on the top wall of the drawer frame 2, so that the structure of the drawer is more compact.
The connecting mechanisms 5 are provided with two groups and are respectively limited on the guide rails 3 on the two side walls of the drawer frame 2 in a sliding way and are used for connecting the drawer 1 to the guide rails 3, and the connecting mechanisms 5 on the same side are connected with the guide rails 3 on the same side and the corresponding sides of the drawer body 1; can slide along the guide rail 3 and at least partially rise or fall relative to the guide rail 3 under the action of the pull cord 43. Each connecting mechanism specifically comprises:
a first hinge lever 51, a second hinge lever 52, a pull lever 53, and a link 55; wherein the connecting rod 55 is provided with cross bars 551 with the same number as the guide rails, two pulleys 552 are arranged on the same guide rail 3, two ends of the cross bars 551 are respectively connected with the two pulleys 552, and each cross bar 551 is connected by a vertical rod 553 to form a whole connecting rod 55; to facilitate the connection of the pull cord 43, a connecting rod 554 parallel to the two cross bars 551 is also connected to the middle of the vertical bar 553.
The first hinge lever 51 is of an "F" shape, and the tail end of the main lever 512 of the first hinge lever 51 is directed to the rear side wall of the drawer frame 2, and the two struts 511 of the first hinge lever 51 are hinged to one ends of the vertical lever 553 and the pull lever 53, respectively.
The second hinge rod 52 is "U" shaped, and two struts 521 of the second hinge rod 52 are hinged to the other ends of the vertical rod 553 and the pull rod 53, respectively.
The pull rods 53 in the two groups of connecting mechanisms are respectively connected with the two side walls of the drawer body 1.
The other end of the pull cord 43 enters the drawer frame from the front end opening thereof, and is connected to the rear end of the main lever 512 of the first hinge lever 51 via a plurality of supporting pulleys.
In the present embodiment, the main lever 512 of the first hinge lever 51 and the main lever 522 of the second hinge lever 52 are disposed parallel to each other; the tie rod 53 and the vertical rod 553 are disposed parallel to each other.

The working principle of this embodiment is described as follows:
when the drawer body needs to be opened, the motor rotates positively to drive the wire coil to rotate positively, the two pull ropes are tightened, the connecting mechanism translates forwards along the guide rail, and the reset spring is lengthened; because the drawer body has a certain weight, and the distance that the upper arm of the first hinging rod extends backwards is smaller, the drawer body cannot be lifted in the process of outwards sliding the drawer body; after the drawer body is pulled to a certain position, the reset spring is stretched sufficiently, the pulling force is large, the motor continuously rotates positively, the first hinge rod rotates by taking the hinge point of the middle support rod and the connecting rod as a base point, a lever is formed, the drawer body is lifted to a set height, the motor stops running and keeps the position, and the drawer body does not descend under the action of the pull rope.
When the drawer needs to be closed, the motor rotates reversely, and the loose pull rope descends to the lowest height under the action of self gravity; the motor continues to rotate reversely, the pulling force of the pull rope on the drawer body continues to be reduced to a certain extent, the reset spring starts to shrink, the drawer body is pulled back to the back until the drawer is closed, and the motor stops working.
Example 2
As shown in fig. 3, the guide rail 3 is arranged on the outer side wall of the drawer frame 2 and is positioned in a cavity between the drawer frame 2 and a shell (not shown in the figure); one end of the return spring is connected with the connecting rod 554, and the other end is connected with the top position of the rear end of the drawer frame 2.
The remainder was the same as in example 1.
