As shown in fig. 1, the drawer assembly includes a drawer outer frame 200 and a drawer body 100 located in the drawer outer frame 200, wherein the drawer body 100 can be lifted relative to the drawer outer frame 200 to ensure that the drawer body 100 can move to a set position, so as to facilitate the use of a user. The drawer outer frame 200 and the drawer body 100 are connected through a linear motion mechanism, the mounting piece 3 of the linear motion mechanism is fixed to the drawer outer frame 200, the first-stage slide rail 4 of the linear motion mechanism is fixed to the drawer body 100, and the first-stage slide rail 4 is slidably connected to the mounting piece 3. As the drawer body 100 moves above the drawer outer frame 200, a part of the linear motion mechanism is also protected outside the drawer body 100, and the user may be injured by the linear motion mechanism during operation. In addition, foreign matters can easily enter the linear motion mechanism, so that the drawer assembly cannot normally work.

In view of the above problems, the present invention provides a drawer assembly, please refer to fig. 2 to 4, which includes a drawer outer frame 200, a drawer body 100 and a linear motion mechanism. The drawer body 100 is mounted on the drawer outer frame 200, the drawer body 100 includes an inner drawer 110 and a protective shell 120 which are connected to each other, a storage space 140 is formed inside the inner drawer 110, the protective shell 120 is disposed outside the inner drawer 110, and a mounting space 130 is formed between the protective shell 120 and the inner drawer 110. The linear motion mechanism includes an installation member 3 and a one-level slide rail 4, the installation member 3 is fixed to the drawer outer frame 200, the one-level slide rail 4 is slidably connected to the installation member 3, and the one-level slide rail 4 is fixedly connected to the drawer body 100, and the linear motion mechanism has an extended state and a contracted state with respect to the installation member 3. In the retracted state, the drawer body 100 is positioned in the drawer frame 200, and the linear motion mechanism is hidden in the drawer frame 200 or between the drawer frame 200 and the drawer body 100, and is not directly exposed. In the extended state, the drawer body 100 is at least partially located outside the drawer outer frame 200, and the portion of the primary slide rail 4 extending out of the drawer outer frame 200 is located in the installation space 130.

The "extending state" and the "contracting state" are two opposite concepts, and the "contracting state" can be understood as an initial state of the linear motion mechanism, and the "extending state" includes a situation where the primary slide rail 4 drives the drawer body 100 to move to an extreme position outside the drawer outer frame 200, and also includes a situation where the primary slide rail 4 drives the drawer body 100 to move to any position between the "contracting state" and the "extreme position".

It should be noted that, in fig. 3 and fig. 4, the linear motion mechanism drives the drawer body 100 to perform a lifting motion relative to the drawer outer frame 200, obviously, the linear motion mechanism may also drive the drawer body 100 to perform a horizontal motion relative to the drawer outer frame 200, or even drive the drawer body 100 to perform a linear motion along other directions relative to the drawer outer frame 200, and correspondingly, only the installation direction and the position of the linear motion mechanism need to be adjusted.

According to the embodiment of the application, for the drawer assembly, when the linear motion mechanism is in the extending state, the drawer body 100 is driven to extend out of the first-level slide rail 4 outside the drawer outer frame 200, the part of the drawer outer frame 200, which is located outside the drawer outer frame 200, is located in the installation space 130, and then the user can not directly contact the linear motion mechanism, so that the protection effect on the user can be achieved, and the user can be prevented from being injured by clamping in the motion process of the linear motion mechanism. Meanwhile, the linear motion mechanism can not be exposed outside, so that foreign matters are prevented from entering the linear motion mechanism to cause motion interference, and the attractiveness of the drawer assembly is ensured.

According to the embodiment of the present application, the "portion of the primary slide rail 4 extending out of the drawer outer frame 200 is located in the installation space 130" includes two situations:

in the first situation, when the drawer body 100 moves to the extreme position, the first-stage sliding rail 4 completely extends to the outside of the drawer outer frame 200, and correspondingly, the first-stage sliding rail 4 is completely fixed in the installation space 130.

In the second situation, when the drawer body 100 moves to the extreme position, the first-stage sliding rail 4 partially extends outside the drawer outer frame 200, and correspondingly, the first-stage sliding rail 4 is partially fixed in the installation space 130.

That is, the size of the protective housing is determined by the extreme position of the drawer body 100. If the drawer body 100 is completely located outside the drawer outer frame 200 in the extreme position, the protective housing may need to cover the entire side wall of the inner drawer 110 in such a case so as to completely cover the exposed linear motion mechanism. If the drawer body 100 is partially positioned outside the drawer outer frame 200 in the extreme position, the outer casing only needs to cover the side wall of the inner drawer 110 to shield the exposed linear motion mechanism. In both cases, the first-stage sliding rail 4 and the side wall of the inner drawer 110 are generally fixed.

Referring to fig. 3 and 4, a plurality of linear motion mechanisms are respectively disposed on two opposite sides of the drawer body 100. In fig. 3 and 4, the linear motion mechanisms are disposed at the left and right sides of the drawer body 100, and then the drawer body 100 is lifted and lowered under the synchronous driving of the two linear motion mechanisms, so that the stability of the movement of the drawer body 100 can be ensured. Of course, the linear motion mechanism may be provided on one side of the drawer body 100, and the guide mechanism may be provided on the other side of the drawer body 100. Alternatively, the linear motion mechanism is provided on all of the left, right, and rear sides of the drawer body 100. Specifically, as long as the linear motion mechanism can drive the drawer body 100 to move, the number and the distribution position of the linear motion mechanism are not limited.

In fig. 3 and 4, the linear motion mechanisms are disposed on the left and right sides of the drawer body 100, and at this time, the protective shell 120 at least includes two side baffles 121 disposed oppositely, and further, the side baffles 121 can shield the linear motion mechanisms. On the basis, the two side baffles 121 can be connected through the front baffle 122, so that the structural strength of the protective shell 120 can be ensured, and the attractiveness of the drawer assembly can be further ensured. Wherein, when the protective shell 120 only comprises two side baffles 121 and a front baffle 122, the rear side of the inner drawer 110 has no protective structure, and the drawer body 100 can be disassembled and assembled through the rear side of the inner drawer 110. Also, since the rear side of the inner drawer 110 is not visible to a user during use, the appearance of the drawer assembly is not affected.

In fig. 3, a guide surface 150 is formed on the top end surface of the drawer body 100, and the guide surface 150 is gradually inclined downward along the direction from the protective shell 120 to the inner drawer 110. By the arrangement of the guide surface 150, even if water is on the top surface of the drawer body 100, the water does not stay at the opening position of the drawer body 100. Especially when the drawer assembly is used in a refrigerator, if water is present on the top end surface of the drawer body 100, it is likely to cause freezing between the drawer assembly and the refrigerator body, and further cause inconvenient opening and closing of the drawer assembly, and the problem of inconvenient opening and closing of the drawer assembly can be solved by the arrangement of the guide surface 150. Meanwhile, the guide surface 150 is arranged, so that the drawer body 100 is lighter and thinner as a whole, and the sense of the user is improved.

In fig. 4, the drawer body 100 is symmetrically provided with two handles 160, and the handles 160 are connected to the protective shell 120 of the drawer. The arrangement of the handle 160 can facilitate the taking and placing of the drawer body 100. Wherein the handles 160 are generally provided at the left and right sides of the drawer body 100. On this basis, in order not to affect the normal opening and closing of the drawer assembly, a mounting groove may be provided on the top end surface of the drawer body 100, and on this basis, the handle 160 may be rotatably connected to the drawer body 100, and the handle 160 may be inserted into the mounting groove. Further, the handle 160 may be rotated into the mounting slot when not in use.

According to the embodiment of the present application, the linear motion mechanism further includes a plurality of intermediate sliding rails (the linear motion mechanism is further described later, and the intermediate sliding rails will be described with reference to the drawings), the primary sliding rail 4 is mounted to the mounting member 3 through the intermediate sliding rails, and in the extended state, the portion of the intermediate sliding rail extending out of the drawer outer frame 200 is located in the mounting space 130. Under the condition, the arrangement of the middle slide rail and the one-level slide rail 4 can ensure the multistage shrinkage of the linear motion mechanism and ensure the motion formation of the drawer body 100.

According to an embodiment of the present application, in order to ensure that the drawer body 100 is located in the drawer outer frame 200 when in the telescopic position, no interference occurs between the drawer body 100 and the drawer outer frame 200, and the drawer outer frame 200 may not be provided with a side plate in a region corresponding to the mounting member 3. Alternatively, an avoiding groove may be formed in the drawer outer frame 200, and the protective shell 120 is located in the avoiding groove when the linear motion mechanism is in the retracted state.

Referring to fig. 5 to 11, the linear motion mechanism according to the embodiment of the present application includes a rotating wheel 1, a rotating driving member (not shown), a mounting member 3, and a primary sliding rail 4. The rotating wheel 1 is wound with a flexible cable 2, the flexible cable 2 is suitable for moving along with the rotation of the rotating wheel 1, and the flexible cable 2 comprises flexible cable 2 sections positioned at two sides of the rotating wheel 1; the rotary driving part is connected with the rotating wheel 1 and is suitable for driving the rotating wheel 1 to rotate; the mounting piece 3 is provided with a guide rail 301, and the mounting piece 3 is provided with a first fixed pulley 6; the primary slide rail 4 is suitable for sliding relative to the guide rail 301; the flexible cable 2 is wound around the first fixed pulley 6, and the sections of the flexible cable 2 at two sides of the rotating wheel 1 of the flexible cable 2 are connected with the primary sliding rail 4.

According to the linear motion mechanism of this application embodiment, it only needs add swiveling wheel 1, rotary driving spare and pulley (including the fixed pulley, can also include the movable pulley in order to realize automatic movement, and wherein, under the condition that does not have special restriction, what the fixed pulley designated is at least one of first fixed pulley 6, second fixed pulley 10, third fixed pulley etc. and then its occupation space is little and simple structure, need not to improve linear motion mechanism's preparation cost by a wide margin. In addition, the rotary wheel 1, the rotary driving piece and the pulley are only needed to be disassembled, so the disassembly and the assembly are convenient.

According to the linear motion mechanism of the embodiment of the application, the rotary driving part can drive the rotating wheel 1 to rotate, and then the rotating wheel 1 drives the flexible cable 2 to move. On the basis, the flexible cable 2 bypasses the first fixed pulley 6, and the flexible cable sections at two sides of the rotating wheel 1 are connected with the primary slide rail 4, so that the flexible cable 2 can drive the primary slide rail 4 to make linear motion relative to the guide rail 301. Along with the different rotation directions of the rotating wheel 1, the primary slide rail 4 makes linear motion in different directions relative to the guide rail 301. In fig. 5, when the rotating wheel 1 rotates clockwise, the flexible cable 2 drives the primary sliding rail 4 to move towards the right side in fig. 5 relative to the guide rail 301; when the rotating wheel 1 rotates counterclockwise, the flexible cable 2 drives the primary slide rail 4 to move towards the left side in fig. 5 relative to the guide rail 301.

It is worth mentioning that the linear motion mechanism is used to make a point on the mechanism perform an accurate or approximately linear motion. That is, the motion of the linear motion mechanism herein includes making an approximately linear motion. In addition, for the pulley block comprising the flexible cable 2 and the first fixed pulley 6, the movement of the flexible cable 2 only drives the first fixed pulley 6 to rotate, and the spatial position of the first fixed pulley 6 is not changed.

According to the embodiment of the present application, the form of the guide rail 301 is not limited. When the first-level slide rail 4 is directly mounted on the guide rail 301, the guide rail 301 only needs to guide the first-level slide rail 4. For example, the guide rail 301 may include a guide groove, and the primary slide rail 4 may move along an extending direction of the guide groove; alternatively, the guide rail 301 may include a guide protrusion, and the primary slide rail 4 may move along an extending direction of the guide protrusion. The guide rail 301 may be integrally formed with the mounting member 3, or may be a separate member fixed to the mounting member 3.

Similarly, the structural form of the primary slide rail 4 is not limited, as long as the primary slide rail 4 can form guiding fit with the guide rail 301, and further the primary slide rail 4 can make linear or approximately linear motion relative to the guide rail 301. For example, the primary sliding rail 4 and the guide rail 301 may be matched by a protrusion and a groove, or a sliding member, such as a pulley, may be installed between the sliding rail and the guide rail 301, and then the primary sliding rail 4 and the guide rail 301 are matched by the sliding member.

The primary slide rail 4 may be an independent component; the slide rail may be formed on a drawer, a shelf, or the like, and in this case, a portion of the drawer, the shelf, or the like to be attached to the guide rail 301 may be regarded as the primary slide rail 4. Of course, a second-level slide rail 5, a third-level slide rail, and the like may also be installed between the first-level slide rail 4 and the guide rail 301, and then the first-level slide rail 4 is not directly installed on the guide rail 301 but installed on the slide rail through the second-level slide rail 5, the third-level slide rail, and the like.

Of course, an intermediate slide rail may be further installed between the primary slide rail 4 and the guide rail 301, and a movable pulley is disposed on the intermediate slide rail, and the flexible cable is wound around the first fixed pulley 6 and the movable pulley (without special limitation, the movable pulley refers to the first movable pulley 8 and the second movable pulley 9 disposed on the secondary slide rail 5, or, in the case of including more intermediate slide rails, the movable pulley disposed on another intermediate slide rail is further included), so that the primary slide rail 4 moves relative to the intermediate slide rail, and the intermediate slide rail moves relative to the guide rail 301. Wherein, the number of middle slide rails is not limited. When the middle slide rail is one, the middle slide rail is also the secondary slide rail 5; the number of the middle slide rails is two, and the middle slide rails comprise a second-level slide rail 5 and a third-level slide rail; the quantity of middle slide rail is three, and the middleware slide rail includes second grade slide rail 5, tertiary slide rail and level four slide rail this moment to the analogize. When the intermediate slide rail is provided, the first-stage slide rail 4 is not directly mounted on the guide rail 301, but is mounted on the slide rail through the intermediate slide rail such as the second-stage slide rail 5 and the third-stage slide rail.

According to the embodiment of the present application, the intermediate sliding rail includes the secondary sliding rail 5 as an example for explanation: the secondary sliding rail 5 is mounted on the guide rail 301 and is suitable for sliding along the guide rail 301, and a first movable pulley 8 and a second movable pulley 9 are arranged on the secondary sliding rail 5; the primary slide rail 4 is arranged on the secondary slide rail 5 and is suitable for moving relative to the secondary slide rail 5; the flexible cable 2 sequentially passes around the first fixed pulley 6, the first movable pulley 8 and the second movable pulley 9. Through setting up second grade slide rail 5, and then make linear motion mechanism can realize multistage flexible, guaranteed linear motion mechanism's flexible stroke.

According to the embodiment of the application, when the linear motion mechanism comprises the first-level slide rail 4 and the second-level slide rail 5, the linear motion mechanism can achieve second-level extension and contraction at the moment and corresponds to three-level linear motion. Of course, the linear motion mechanism may further include a third-stage slide rail, a fourth-stage slide rail, a fifth-stage slide rail, and the like, and the number of the specific slide rails (without special limitation, the slide rail refers to at least one of the first-stage slide rail 4, the second-stage slide rail 5, the third-stage slide rail, and the like) is not limited, and may be determined according to the requirement. The first-stage slide rail 4 is a first slide rail which is driven to extend or contract when the rotary driving piece rotates; the second-stage slide rail 5 refers to a second slide rail which is extended or contracted by the continuous movement of the rotary driving part when the first-stage slide rail 4 moves to the limit position; the third-stage slide rail refers to a third slide rail which is extended or contracted by the continuous movement of the rotary driving part when the second-stage slide rail 5 moves to the limit position, and the rest can be done in the same way.
