2 to 10 , the linkage mechanism 60 between the drawer 30 and the drawer 40 is taken as an example to introduce the linkage mechanism of an embodiment of the present invention.

The linkage mechanism 60 includes a movable blocking block 61 , a pushing portion 65 and a blocking protrusion 69 . The movable blocking block 61 is rotatable around an axis extending in the lateral direction (referring to the left and right directions marked in the figure) and can be moved in the lateral direction at the bottom of the upper drawer 40 of the two adjacent drawers 30 and 40 . The pushing portion 65 is disposed on the top of the lower drawer 30 , specifically on the lateral side wall. The stopper protrusion 69 is disposed on the lateral side wall of the storage compartment and protrudes outward from the inner wall of the storage compartment 101 . The stopper protrusion 69 may be an independently fabricated part, which is installed on the inner wall of the storage compartment 101 , or may be a structure integrally formed with the inner wall of the storage compartment 101 .

The linkage mechanism 60 is configured such that when the two adjacent drawers 30 and 40 are both in a closed state (as shown in FIGS. 2 and 5 ), the pushing portion 65 is located just behind the movable blocking block 61 (which can make it abut against the movable blocking block 61 ). The rear side of the block 61 can also be located behind the movable blocking block 61 for a certain distance). When the lower drawer 30 is moved forward and opened, the push portion 65 pushes the movable blocking block 61, thereby driving the upper drawer 40 to move forward synchronously. When the upper drawer 40 is pushed to the middle position (as shown in FIG. 3 ), the movable blocking block 61 is pressed by the blocking protrusion 69 to overcome an elastic force (generated by an elastic element), and move toward the drawer from the original state. move laterally in the direction shown in FIG. 4 (to the left from the state shown in FIG. 4 ) to disengage the pusher 65 , thereby releasing the linkage between the two adjacent drawers 30 and 40 (as shown in FIG. 5 ), so that the lower drawer 30 continues to move forward and open independently ( After the movable blocking block 61 passes over the blocking protrusion 69, it returns to its original state under the action of the aforementioned elastic force). At this time, the upper drawer 40 is no longer affected by the lower drawer 30 and stays at the intermediate position. Of course, the user can also continue to pull the upper drawer 40 forward to fully open it.

After the two adjacent drawers 30 and 40 are both opened, if the user wants to close the two drawers, the upper drawer 40 can be completely closed first, and then the lower drawer 30 can be closed. Before closing the lower drawer 30 , the pushing portion 65 is located in front of the movable blocking block 61 . At this time, the lower side drawer 30 is pushed back until the pushable portion 65 contacts the front of the bottom end of the movable blocking block 61 (refer to FIG. 7 ), so that the movable blocking block 61 is rotated backward against the action of an elastic torque, thereby making the movable blocking block 61 rotate backward. Its bottom height is raised to go over the push portion 65 , so that the movable blocking block 61 returns to the front side of the push portion 65 . Then, the movable blocking block 61 is turned back to its original position under the action of the aforementioned elastic torque (refer to FIG. 5 ), that is, the entire linkage mechanism 60 is restored to its original state. In addition, when the pushing portion 65 is in front of the movable blocking block 61 , keeping the lower drawer 30 stationary, and pulling the upper drawer 40 forward, the movable blocking block 61 can also pass over the pushing portion 65 .

As shown in FIG. 4 , the push portion 65 extends upward from the top rear end of the lower drawer 30 . The pushing portion 65 can be integrally formed with the side wall of the drawer, or can be processed separately and then installed.

As shown in FIG. 7 , each linkage 60 also includes a box body and a compression spring 66 . The box body is installed at the bottom of the upper drawer 30 . The movable blocking block 61 is disposed in the box body, and the bottom of the movable blocking block 61 protrudes out of the box body through the opening 635 at the bottom of the box body to cooperate with the pushing portion 65 . The side portion (right side) of the movable blocking block 61 protrudes out of the box body through the opening 643 of the side portion of the box body, so as to cooperate with the stopper protrusion 69 . Specifically, the box body may include a box body body 63 and a box cover 64 . The side of the box body 63 is open, and the box cover 64 is covered on the box body 63 . The box cover 64 is provided with a hole 641 so that the screw 642 can pass through and cooperate with the threaded hole 633 opened on the box body 63 to fix the box cover 64 .

As shown in FIG. 9 , when no external force is applied (for example, when all the drawers are closed), the rear surface 613 of the movable blocking block 61 is a vertical surface, so that the pushing portion 65 can better push it. . The front surface 614 of the movable blocking block 61 is an inclined surface extending forward gradually from bottom to top, so that when it comes into contact with the push portion 65 , it can go over the push portion 65 with less effort.

As shown in FIG. 8 , there are mounting posts 631 extending in the lateral direction in the box. The compression spring 66 is sleeved on the mounting post 631 . The movable blocking block 61 is rotatably mounted on the mounting post 631, and the compression spring 66 is located between the movable blocking block 61 and the box body, so that when the compression spring 66 is squeezed by the movable blocking block 61, the aforementioned elastic force is provided .

A curved elastic sheet 618 extends from the rear surface of the movable blocking block 61 , which abuts against the rear wall 639 of the box body to generate elastic deformation under pressure, thereby applying the elastic torque to the movable blocking block 61 . The curved elastic piece 618 may be in a curved shape with the axis extending in the lateral direction of the drawer. The curved elastic sheet 618 can be integrally formed with the movable blocking block 61, and can be made of POM material to improve its rigidity, strength, and wear resistance, and to save costs.

As shown in FIG. 8 , the movable blocking block 61 is formed with a sleeve portion 611 whose one end is open (the left end is shown in the figure), and the sleeve portion 611 is sleeved on the mounting post 631 . The end surface 6113 of the other end (ie, the right end in the figure) of the sleeve portion 611 is a partial spherical surface, and the end extends out of the box body through the opening 643 on the side of the box body for matching with the stopper protrusion 619 . The sleeve portion 611 is configured as a spherical surface so that it can pass over the stop projection 619 with less effort.

As shown in FIG. 9 and FIG. 10 , a limiting groove 6312 is defined on the peripheral surface of the mounting post 631 , the inner wall of the sleeve portion 611 has a radially protruding positioning protrusion 612 , and the positioning protrusion 612 is located in the limiting groove 6312 . When the movable blocking block 61 rotates, the positioning protrusion 612 can only move within the range of the limiting groove 6312 , thereby limiting the rotation range of the movable blocking block 61 .

Specifically, when the two adjacent drawers 30 and 40 are in the closed state, as shown in FIG. 9 , the positioning protrusion 612 is pressed against the front wall of the limiting groove 6312 , so that the movable blocking block 61 cannot rotate forward. Therefore, it is convenient for the pushing portion 65 to push the movable blocking block 61 to move forward.

When the pusher 65 is in front of the movable blocking block 61 and pushes the lower drawer 30 backwards, the movable blocking block 61 is allowed to rotate backward, at most until the positioning protrusion 612 abuts against the rear wall of the limiting groove 6312 (As shown in Fig. 10), the rotation is stopped. At this time, the movable blocking block 61 is enough to pass over the pushing portion 65, so as to return to the front side of the pushing portion 65, and then return to the original position under the action of elastic torque.

The linkage mechanism of the refrigerator of the present invention is simple in structure, but has a very practical function. And the number of parts is small, the possibility of failure is small, and the reliability is high.

In some embodiments, in each group of two adjacent linkage mechanisms 60, the position of the stop protrusion 69 of the linkage mechanism 60 located on the lower side can be compared with the position of the stop protrusion 69 of the linkage mechanism 60 located on the upper side more forward. In this way, after multiple drawers are opened, the opening degree of the drawers from top to bottom increases sequentially, similar to the stepped structure, so that the upper drawer will not completely block the upper opening of the adjacent lower drawer, which is convenient for users to observe and access. thing.

As shown in Figures 1-10, only one linkage mechanism 60 is provided between every two adjacent drawers. Of course, two left-right symmetrical linkage mechanisms 60 can also be arranged between every two adjacent drawers, so that both ends of the upper drawer are pushed and moved forward more smoothly.

By now, those skilled in the art will recognize that, although various exemplary embodiments of the present invention have been illustrated and described in detail herein, the present invention may still be implemented in accordance with the present disclosure without departing from the spirit and scope of the present invention. The content directly determines or derives many other variations or modifications consistent with the principles of the invention.
