DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Moreover, repeated reference numerals or designations may be used in various embodiments. These iterations are merely for simplicity and clarity of describing the present invention, and are not intended to represent any correlation between the different embodiments or configurations discussed.

As shown in fig. 1 to 6, the present invention provides a drawer assembly 100, wherein the drawer assembly 100 is accommodated in the accommodating space. In the present embodiment, the storage space refers to the inside of the refrigerator, but the storage space may also refer to another cabinet as long as the drawer assembly 100 can be placed therein. Of course, the receiving space is open to the front side to facilitate the drawer assembly 100 to be pulled out forward, and includes a rear wall, a bottom wall, a top wall, and two side walls.

The drawer assembly 100 includes a drawer 10, a cover 20 covering the upper side of the drawer 10, and a sliding assembly 30 connected between the drawer 10 and the side wall, wherein the sliding assembly 30 facilitates the corresponding movement of the cover 20 to the front side during the process of pulling out the drawer 10. Of course, in this embodiment, a slide is also formed on the drawer 10, and the drawer 10 can slide out from the receiving space through the slide. The drawer 10 comprises a bottom plate and side plates 1 extending upwards from the bottom plate.

Specifically, the sliding assembly 30 includes a sliding rail 3 fixed on the side wall, the sliding rail 3 includes a first horizontal section 31 extending horizontally and a first ascending section 32 extending upward from the first horizontal section 31, the sliding assembly 30 further includes a sliding block 4 capable of moving along the sliding rail 3, a connecting portion 41 fixed to the cover body 20 is formed on the sliding block 4, and the connecting portion 41 is located on the front side of the sliding block 4.

Thus, specifically, as shown in fig. 3 to 6, when the drawer 10 is pulled forward, the cover 20 moves forward synchronously with the drawer 10, and the cover 20 drives the sliding block 4 to move forward along the first horizontal segment 31; when the connecting portion 41 moves to the first rising section 32, that is, the relative front portion of the slider 4 moves to the first rising section 32, the front portion of the slider 4 moves upward along the first rising section 32, and the corresponding cover 20 is gradually lifted upward, so as to be separated from the drawer 10. After the cover 20 is separated from the drawer 10, the drawer 10 is further moved forward, one end of the cover 20 is lifted up and is maintained at a certain height without moving; during further forward movement of the drawer 10, the other end of the cover 20 slides on the upper side of the drawer 10.

In the present embodiment, as shown in fig. 2, the first rising section 32 extends smoothly upward from the first horizontal section 31, so that the sliding block 4 can also smoothly transition into the first rising section 32 along the first horizontal section 31.

As shown in fig. 1, the sliding assembly 30 further includes an elastic member 5 connected between the slider 4 and the side wall. When the drawer 10 is pulled forward, the elastic member 5 is gradually stretched; when the connecting portion 41 moves to the first rising section 32, the elastic member 5 pulls the slider 4 and abuts the slider 4 against the first rising section 32. In the present embodiment, the elastic member 5 is a spring. When the drawer 10 is not opened, that is, when the drawer 10 is completely accommodated in the accommodating space, the spring is in a stretched or unstressed state.

When the drawer 10 is opened forwards, the sliding block 4 drives the elastic piece 5 to stretch forwards; when the connecting portion 41 moves to the first rising section 32, the elastic member 5, which is still stretched, has a tendency to pull the slider 4 to move backward, and therefore, the slider 4 receives a force in the backward direction; but at the same time, the slide 4 can be held against the first rising section 32 due to the holding of the first rising section 32. Since the tensile force of the spring is relatively large, the weight of the cover body 20 is relatively light, and therefore, the friction force between the slider 4 and the first rising section 32 can fully bear the weight of the cover body 20, so that the cover body 20 cannot fall back downward.

Specifically, as shown in fig. 1 and fig. 2, in the present embodiment, the sliding assembly 30 further includes a seat 9, and the seat 9 is fixed on a side wall of the accommodating space. The seat 9 includes a first receiving portion 91 and a second receiving portion 92 connected to each other, and the second receiving portion 92 is located at the opposite rear side of the first receiving portion 91. The first receiving portion 91 comprises two parallel plates parallel to the side walls, the slide rails 3 are symmetrically formed on the parallel plates in a penetrating manner, and the slide block 4 can move between the two parallel plates. The second receiving portion 92 is elongated and extends in the horizontal direction. One end of the elastic element 5 is fixed at the free end of the second accommodating part 92, and the other end is fixed with the slider 4.

In addition, the rear side of the sliding block 4 forms a butt joint part, the sliding block 4 assembly further comprises a butt joint rod 6 fixed on the side wall, and when the drawer 10 is accommodated in the accommodating space, the butt joint part is in butt joint with the butt joint rod 6. The matching of the butt joint rod 6 and the butt joint part plays a limiting role to prevent the slide block 4 from deviating in position in the moving process. Specifically, the docking lever 6 is also accommodated in the second accommodating portion 92.

Of course, the sliding assembly 30 further includes a supporting member 7, the supporting member 7 extends in a vertical direction, and an upper end thereof is connected to the cover body 20, and a lower end thereof is connected to the sliding block 4. Specifically, the opposite front side portion of the slider 4 protrudes towards both sides to form the connecting portion 41, and specifically, the two connecting portions 41 are cylindrical, and the diameter of the two connecting portions 41 is smaller than the width of the rail, so that the connecting portions 41 can slide in the rail. The lower end of the supporting member 7 protrudes to form an engaging portion 71, and the engaging portion 71 is engaged with one of the connecting portions 41. Therefore, in the moving process of the cover body 20, the matching portion 71 and the connecting portion 41 can be clamped with each other to drive the slider 4 to move synchronously.

In the present embodiment, the drawer 10 is further provided with a first fixing block 11, and the first fixing block 11 is fixed to the side plate 1 of the drawer 10. When the drawer 10 is pulled forward, the first fixed block 11 moves forward synchronously with the sliding block 4; after the connecting portion 41 moves to the first rising section 32, the sliding block 4 gradually moves upward in an inclined manner, and thus the first fixing block 11 and the sliding block 4 gradually separate from each other; after the complete disengagement, the first fixing block 11 continues to move along with the drawer 10, while the sliding block 4 is kept in the inclined state and is stably fixed at the first rising section 32 by the elastic member 5. When the drawer 10 is pushed back, the first fixing block 11 gradually contacts the sliding block 4 and pushes the sliding block 4 to synchronously move backwards, and the cover 20 also moves downwards and backwards along with the drawer 10.

Specifically, as shown in fig. 4 and 6, the slider 4 includes a recessed portion 43 formed by being recessed from the bottom toward the top, and a first abutting portion 44 and a second abutting portion 45 provided on the front and rear sides of the recessed portion 43, respectively. When the drawer 10 is pulled forward, the first fixed block 11 pushes the first abutting portion 44 to move forward, and of course, due to the pulling force of the elastic member 5, the first abutting portion 44 and the first fixed block 11 tightly abut against each other.

After the connecting portion 41 moves to the first rising section 32, the elastic member 5 pulls the slider 4 to move upward and turn backward at the same time, the first fixed block 11 is gradually separated from the first abutting portion 44 and the second abutting portion 45, the first abutting portion 44 moves upward to be higher than the upper surface of the first fixed block 11, the second abutting portion 45 moves upward but still lower than the upper surface of the first fixed block 11, and the first fixed block 11 still moves forward along with the drawer 10.

When the drawer 10 is pushed back, the first fixing block 11 moves backward to contact with the second abutting portion 45, the first fixing block 11 pushes the second abutting portion 45 to move backward, so that the slider 4 gradually moves downward and backward along the slide rail 3, and the cover 20 also gradually moves downward and covers the upper surface of the drawer 10. Of course, when the slider 4 moves backward on the first horizontal segment 31, since the elastic member 5 is still in a stretched state, the elastic member 5 pulls the slider 4 to move backward, and the first abutting portion 44 of the slider 4 abuts against the slider 4.

In addition, as shown in fig. 3 to 6, the sliding assembly 30 further includes a chain member 8 slidable in the sliding rail 3, and the chain member 8 is connected to the front side of the sliding block 4. Specifically, the chain-shaped element 8 is formed by connecting a plurality of unit elements, and the distance between two adjacent unit elements is kept consistent, so that the chain-shaped element 8 cannot be stretched or compressed, and when two unit elements are connected with each other in a linear direction, the connection between the two unit elements is stable.

Specifically, the slide rail 3 further includes an extension section extending from the first rising section 32, and the extension length of the chain element 8 is smaller than that of the slide rail 3, so that the chain element 8 and the slide block 4 thereof can slide in the slide rail 3. The extending section includes a second horizontal section 33 extending from the first rising section 32, a second rising section 34 extending from the second horizontal section 33, and a third horizontal section 35 extending from the second rising section 34, and after the connecting portion 41 moves to the first rising section 32, the chain-shaped element 8 moves along the extending section and finally abuts against the end of the third horizontal section 35.

Therefore, as mentioned above, the overall shape of the slide rail 3 is "S" shape, and the chain element 8 and the sliding block 4 cooperate to further enhance the stability of the drawer assembly 100 of the present invention. And, because of the stability of the chain element 8 and the large friction force formed between the chain element and the inner wall surface of the slide rail 3, the slider 4 can be further prevented from moving downward at the first rising section 32.

In addition, as shown in fig. 3 to 6, a second fixing block 12 is further disposed on the drawer 10, and when the drawer 10 is pushed back, the second fixing block 12 contacts the chain-shaped element 8 and pushes the chain-shaped element 8 to move backwards. The second fixing block 12 is also fixed on the side plate 1 of the drawer 10, and functions similarly to the first fixing block 11, and the second fixing block 12 further improves the stability of the whole sliding assembly 30 by pushing the chain-shaped element 8, and thus the sliding block 4, to move downwards when the drawer 10 is pushed back.

In summary, the drawer assembly 100 provided by the present invention, through the cooperation of the sliding block 4 and the sliding rail 3, the cover 20 can be gradually lifted upwards in the process of moving forward when the drawer 10 is being pulled open, so that after the drawer 10 is completely pulled open, the cover 20 cannot cover the drawer 10, and the taking of the articles in the drawer 10 cannot be correspondingly affected.

It should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art will be able to make the description as a whole, and the embodiments may be appropriately combined to form other embodiments as will be appreciated by those skilled in the art.

The above detailed description is merely illustrative of possible embodiments of the present invention and is not intended to limit the scope of the invention, which is intended to include all equivalent embodiments or modifications within the scope of the present invention without departing from the technical spirit of the present invention.
