The drawer assembly provided by the embodiment of the invention is suitable for various occasions, such as various devices like a refrigerator, a locker, a desk and the like, and is especially suitable for the refrigerator.

When the drawer component is applied to refrigeration equipment such as a refrigerator, the drawer component in the refrigeration equipment needs cold energy supply, and in some cases, an air duct is arranged at the rear of the drawer body, at the moment, the rotary driving piece can be arranged in the air duct, the ventilation of the air duct is not influenced, and the rotary driving piece does not need to occupy the space of the drawer component additionally.

It will be appreciated that the two sides of the drawer body 12 are slidably connected to a drawer frame (not shown), one of the drawer frame and the drawer body is provided with a guiding groove, the other is provided with a guiding protrusion, the guiding protrusion is slidably matched with the guiding groove, and the drawer frame plays a role in supporting and guiding the drawer body 12 at the two sides thereof, so as to help to reduce the pressure born by the rotary driving member 13, reduce the driving force, and make the movement of the drawer body 12 smoother.

Wherein, the drawer frame can be the frame structure of the drawer assembly. When the drawer body is installed in the storage cabinet, the drawer frame is also formed on the side wall of the storage cabinet, such as a guide groove for supporting the drawer body 12 is formed on the container of the refrigerator, the structure is simple, and parts can be reduced.

It will be appreciated that, as shown in fig. 1 and 2, the rear wall 122 of the drawer body 12 is connected with the bottom wall 121 through an arc surface 123, and when the drawer body 12 falls to the ground, the arc surface 123 can reduce the impact of the falling on the drawer body 12, so as to protect the drawer body 12. The rotary driving piece 13 is located in the space below the arc surface 123, the rotary driving piece 13 utilizes the unused space of the drawer assembly, the drawer assembly does not need to be provided with a special installation space of the rotary driving piece 13, the installation of the rotary driving piece 13 cannot influence the volume of the drawer body 12, and the volume maximization of the drawer body 12 is realized.

The rear wall 122, the bottom wall 121 and the circular arc surface 123 may be formed as one piece, or may be formed by combining a plurality of pieces, and the connection method of the rear wall 122, the bottom wall 121 and the circular arc surface 123 is not limited here.

It can be understood that the rotating wheel 1 and the rotary driving piece 13 are located at one end of the first-stage sliding rail 4 in the sliding direction, so that the rotating wheel 1 and the rotary driving piece 13 are convenient to disassemble and assemble, the extending path of the flexible cable 2 is also facilitated to be simplified, the flexible cable 2 is convenient to be arranged, and the structure is simplified.

The rotating wheel 1 and the rotary driving member 13 may be located at the rear end of the primary sliding rail 4. The front-rear direction is understood to mean that the extending direction of the primary slide rail 4 is the front, and the restoring direction of the primary slide rail 4 is the rear. As shown in fig. 1 to 5, the rotary wheel 1 and the rotary driving member 13 are located at the rear end of the primary slide rail 4.

It will be appreciated that referring to fig. 1 to 5, the rotary wheel 1 and the rotary driving member 13 are located outside the mounting member 3, the rotary wheel 1 and the rotary driving member 13 are not directly connected to the mounting member 3, and when the rotary driving member 13 is a motor, the influence of the vibration of the rotary driving member 13 and the rotary wheel 1 on the stability of the primary slide rail 4 can be reduced.

The first-stage slide rail 4 is directly connected with the drawer body 12, the rotating wheel 1 and the rotary driving piece 13 can be arranged on the frame of the drawer assembly, the rotating wheel 1 and the rotary driving piece 13 are not directly hard-connected with the drawer body 12, but are in soft connection through the flexible rope 2, and the movement stability of the drawer body 12 can be improved. When the drawer component is installed to the storage cabinet, the storage cabinet can be refrigeration equipment such as a refrigerator, a freezer, a vending cabinet and the like, the rotary wheel 1 and the rotary driving piece 13 can be installed to the cabinet body 14 of the refrigeration equipment, and the rotary wheel 1 and the rotary driving piece 13 are not directly hard-connected with the drawer body 12, so that vibration of the rotary driving piece 13 is not directly transmitted to the drawer body 12, and the stability of the drawer body 12 is better.

When the rotary driving piece 13 is a motor, the motor can be arranged at any position on the rear side of the mounting piece 3, the transmission efficiency is high, and the wire does not need to move along with the first-stage sliding rail 4.

It will be appreciated that the rotary wheel 1 and the rotary drive 13 are laterally disposed behind the drawer body 12, i.e. the axis of rotation of the output shafts of the rotary wheel 1 and the rotary drive 13 are laterally disposed behind the drawer body 12.

It is to be understood that the rotation axes of the output shafts of the rotary wheel 1 and the rotary driving member 13 are horizontally arranged, or the rotation axes form a small included angle with the horizontal plane, which is not perpendicular to the horizontal plane, so that the rotary driving member 13 and the rotary wheel 1 can utilize the space below the arc surface 123 of the drawer body 12, reduce the volume of the linear transmission mechanism, and further reduce the space occupied by the rotary driving member and the linear transmission mechanism

Transverse, it is also understood that the axis of rotation of the rotating wheel 1 forms a preset angle with the surface of the mounting 3, the preset angle being smaller than 90 °.

The preset angle is smaller than 90 degrees, that is, the rotation axis of the rotating wheel 1 is not perpendicular to the mounting piece, the rotation axis of the rotating wheel 1 is not perpendicular to the sliding direction of the primary sliding rail 4, and the preset included angle is as small as possible, so that the thickness of the linear transmission mechanism is reduced, and the linear transmission mechanism is thinner. When the preset angle is 0 °, the plane where the rotation axis of the rotating wheel 1 is located is parallel to the surface of the mounting member (the plane where the sliding direction of the primary pulley is located), the axial directions of the rotating driving member 13 and the rotating wheel 1 are not in the same direction as the thickness direction of the linear transmission mechanism, the axial directions of the rotating driving member 13 and the rotating wheel 1 extend along the length or width direction of the linear transmission mechanism, the thickness of the whole linear transmission mechanism cannot be influenced due to the axial lengths of the rotating driving member 13 and the rotating wheel 1, and the thickness of the linear transmission mechanism can be reduced to be smaller.

The preset angle can be 60 degrees, 45 degrees, 30 degrees, 20 degrees, 10 degrees, 0 degrees and the like, and particularly can be adjusted according to the installation space.

It can be understood that, referring to fig. 3 and 4, the linear transmission mechanism further includes a second adjusting member 10, where the second adjusting member 10 is used to adjust the extending direction of the second flexible cable segment 202, so that the leading-out end of the second flexible cable segment 202 from the second adjusting member 10 is parallel to the sliding groove of the fixed pulley 6, so as to solve the problem that an included angle exists between the extending direction of the second flexible cable segment 202 and the sliding groove direction of the fixed pulley 6, avoid the second flexible cable segment 202 generating a force perpendicular to the sliding groove direction of the fixed pulley 6, reduce the movement resistance between the second flexible cable segment 202 and the fixed pulley 6, and improve the movement stability of the second flexible cable segment 202.

The second adjusting member 10 is located on the path of the second flexible segment 202 from the rotating wheel 1 to the fixed pulley 6, and the second flexible segment 202 is wound around the second adjusting member 10 and extends toward the fixed pulley 6.

As shown in fig. 3 and 4, when the second flexible cable segment 202 is higher from the leading-out end of the rotating wheel 1 than the position of the second flexible cable segment entering the fixed pulley 6, the lower part of the second adjusting member 10 is parallel to the position of the second flexible cable segment entering the fixed pulley 6, and the second flexible cable segment 202 bypasses the lower part of the second adjusting member 10 and extends towards the fixed pulley 6. When the second flexible cable section 202 is lower than the position (not shown) of the fixed pulley 6 from the outlet end of the rotating wheel 1, the upper side of the second adjusting member 10 is parallel to the position of the fixed pulley 6, and the second flexible cable section 202 bypasses the upper side of the second adjusting member 10 and extends towards the fixed pulley 6.

It should be noted that, as shown in fig. 3 and fig. 4, when the plane of the rotation axis of the fixed pulley 6 is perpendicular to the plane of the sliding direction of the primary sliding rail 4 (the sliding groove of the fixed pulley 6 is parallel to the sliding direction of the primary sliding rail 4), the second adjusting member 10 may be provided to adjust the extending path of the second flexible cable segment 202 so as to adjust the friction resistance between the second flexible cable segment 202 and the fixed pulley 6; when the plane of the rotation axis of the fixed pulley 6 is parallel to the plane of the sliding direction of the primary sliding rail 4 (not shown in the figure, the sliding groove of the fixed pulley 6 is perpendicular to the sliding direction of the primary sliding rail 4), the height of the second flexible cable segment 202 has less influence on the motion resistance, and the second adjusting member 10 may not be provided.

It will be appreciated that as shown in fig. 4, the second adjusting member 10 includes a shaft 1002 and a wheel body 1001, the shaft 1002 is connected to the mounting member 3, the wheel body 1001 is rotatably connected to the mounting member 3 through the shaft 1002, and the second cord segment 202 bypasses the wheel body 1001 toward the side of the mounting member 3. The second cord segment 202 bypasses the rotatable wheel body 1001 such that the cooperation of the second cord segment 202 with the wheel body 1001 reduces the friction between the second adjustment member 10 and the second cord segment 202 such that the movement of the second cord segment 202 is smoother.

As shown in fig. 4, the second flexible cable segment 202 bypasses the lower part of the wheel body 1001, and the lower part of the wheel body 1001 is parallel to the sliding groove of the fixed pulley 6, so that the second flexible cable segment 202 extends to the fixed pulley 6 in a straight manner, and the friction force between the second flexible cable segment 202 and the fixed pulley 6 is reduced.

The wheel 1001 is rotatably connected with the shaft 1002, and the shaft 1002 is fixed on the mounting member 3 to realize rotation of the wheel 1001; or, wheel 1001 and axis body 1002 fixed connection, axis body 1002 rotate and connect in mounting 3, realize wheel 1001's rotation, simple structure and make things convenient for the dismouting, specifically can select as required.

Of course, the second adjusting member 10 may also be a guide block fixedly mounted on the mounting member 3, and the second adjusting member 10 may play a role of adjusting the extending path of the second cable segment 202, so as to ensure stable transmission of the cable 2 and reduce the sliding resistance of the primary sliding rail 4.

It can be understood that the linear transmission mechanism further includes a first adjusting member (not illustrated in the figure, the principle of the first adjusting member is the same as that of the second adjusting member 10, and the first adjusting member is used for adjusting different portions of the flexible cable 2, and reference may be made to the structure and principle of the second adjusting member 10 described above), where the first adjusting member is used for guiding and adjusting the extending path of the first flexible cable segment 201, and the first adjusting member is used for adjusting the distances between different positions of the first flexible cable segment 201 and the mounting member 3, so as to solve the problem that an included angle exists between the extending direction of the first flexible cable segment 201 and the moving direction of the first slide rail 4, avoid the first flexible cable segment 201 generating a force perpendicular to the sliding direction of the first slide rail 4, reduce the sliding resistance of the first slide rail 4, and improve the sliding stability of the first slide rail 4.

The first adjusting piece is located on the path between the first flexible cable section 201 and the first-stage sliding rail 4 from the rotating wheel 1, the first flexible cable section 201 bypasses the first adjusting piece and extends towards the first-stage sliding rail 4, so that the extending path of the first flexible cable section 201 is adjusted through the first adjusting piece, after the first flexible cable section 201 is adjusted through the first adjusting piece, the first flexible cable section 201 extends straight to the first-stage sliding rail 4, and the first flexible cable section 201 after the first adjusting piece is adjusted is parallel to the sliding direction of the first-stage sliding rail 4.

It will be appreciated that the structure of the first adjustment member may be the same as or different from the structure of the second adjustment member 10, and may be selected as desired. For example, the first adjusting member may also include a shaft and a wheel, the shaft is connected to the mounting member, the wheel is rotatably connected to the mounting member through the shaft, and the first flexible cable section bypasses the wheel and extends toward the primary rail. Or, the first adjusting piece can also be a guide block fixedly mounted on the mounting piece, the first adjusting piece can play a role in adjusting the extending path of the first flexible cable section, and the second adjusting piece can play a role in adjusting the extending path of the second flexible cable section so as to ensure stable transmission of the flexible cable and reduce the sliding resistance of the first-stage sliding rail.

Referring to fig. 3 and 4, the leading-out end of the first flexible cable section 201 is led out from the lower part of the rotating wheel 1, at this time, the extending direction of the first flexible cable section 201 to the first stage sliding rail 4 is parallel to the sliding direction of the first stage sliding rail 4, and the extending path of the first flexible cable section 201 can not be adjusted, and the first adjusting member is not required. The leading-out end of the second flexible cable section 202 is led out from the upper side of the rotary wheel 1, the leading-out end of the second flexible cable section 202 is higher than the fixed pulley 6, a second adjusting piece 10 is arranged on one side, close to the rotary wheel 1, of the mounting piece 3, a wheel body 1001 of the second adjusting piece 10 can rotate relative to the mounting piece 3, the leading-out end of the second flexible cable section 202 bypasses the lower side of the wheel body 1001, the lower side of the wheel body 1001 is parallel to a sliding groove of the fixed pulley 6, the second flexible cable section 202 extends to the fixed pulley 6 after being led out from the wheel body 1001, and friction force between the second flexible cable section 202 and the fixed pulley 6 is reduced as much as possible.

It can be understood that, as shown in fig. 3 and 5, a plurality of intermediate slide rails are arranged between the primary slide rail 4 and the guide rail 301, and the primary slide rail 4 is mounted on the guide rail 301 through the intermediate slide rails; the middle sliding rail is provided with a movable pulley, and the flexible rope 2 sequentially bypasses the fixed pulley 6 and the movable pulley, so that the primary sliding rail 4 performs multistage linear motion relative to the middle sliding rail.

Wherein the number of intermediate slide rails is not limited. If the number of the middle slide rails is one, two or three, the number of the middle slide rails is two, and the middle slide rails comprise a second-stage slide rail and a third-stage slide rail; the number of the middle sliding rails is three, and the middle sliding rails comprise a second-level sliding rail, a third-level sliding rail and a fourth-level sliding rail, and the like. When an intermediate rail is provided, the primary rail 4 is not directly mounted to the rail 301 but is mounted to the rail 301 via the intermediate rail. For example, taking the example that the linear driving mechanism includes the intermediate slide rail 5, at this time, the intermediate slide rail may be matched with the guide rail 301 and linearly move along the guide rail 301, and the primary slide rail 4 may be matched with the intermediate slide rail 5 and linearly move along the intermediate slide rail 5.

It should be noted that, without special limitation, the movable pulleys refer to all movable pulleys disposed on the intermediate slide rail, for example, one intermediate slide rail is disposed, and the first movable pulley 8 and the second movable pulley 9 on the second slide rail; under the condition that the middle sliding rail comprises a multi-stage sliding rail, the movable pulleys arranged on other middle sliding rails are further included.

When the linear transmission mechanism simultaneously comprises the first-stage slide rail 4 and the middle slide rail, the second-stage expansion, the third-stage expansion and the like can be realized. Of course, the linear driving mechanism may further include three-stage slide rails, four-stage slide rails, five-stage slide rails, and the number of specific slide rails (in the case of no special limitation, the slide rails refer to at least one of the first-stage slide rails, the second-stage slide rails, the third-stage slide rails, and the like) is not limited, and may be determined according to requirements. In some cases, the primary slide rail 4 refers to a slide rail directly connected to the drawer body; the middle slide rail refers to a slide rail between the primary slide rail and the mounting member. That is, the first-stage slide rail 4 is a part directly connected to the drawer body 12, the second-stage slide rail is a next-stage slide rail directly connected to the first-stage slide rail 4, the third-stage slide rail is a next-stage slide rail directly connected to the second-stage slide rail, and so on, and the last-stage slide rail is connected between the previous-stage slide rail and the mounting member 3.

As shown in fig. 3 and 5, an example of providing one intermediate rail 5 is described.

The middle sliding rail is arranged on the guide rail 301 of the mounting piece 3 and is suitable for sliding along the guide rail 301, and the middle sliding rail 5 is provided with a first movable pulley 8 and a second movable pulley 9; the primary slide rail 4 is arranged on the middle slide rail 5 and is suitable for moving relative to the middle slide rail 5; the second flexible cable section 202 sequentially bypasses the fixed pulley 6, the first movable pulley 8 and the second movable pulley 9 and is connected to the primary slide rail 4.

The first movable pulley 8 and the second movable pulley 9 are respectively positioned at two ends of the middle slide rail 5, so that the movement stroke of the middle slide rail 5 relative to the guide rail 301 is ensured. As shown in fig. 5, the first movable pulley 8 is disposed at the rear end of the intermediate slide rail 5, and the second movable pulley 9 is disposed at the front end of the intermediate slide rail 5. Similarly, in the case where the stroke of the intermediate slide 5 meets the requirement, the first movable sheave 8 and the second movable sheave 9 may be disposed at other positions of the intermediate slide 5.

It will be appreciated that with reference to fig. 5, the second flex cable segment 202 comprises a first sub-flex cable segment 203, a second sub-flex cable segment 204 and a third sub-flex cable segment 205. Wherein the first sub-cord segment 203 is located between the fixed pulley 6 and the first movable pulley 8; the second sub-flexible cable section 204 is positioned between the first movable pulley 8 and the second movable pulley 9; the third sub-cord segment 205 is located between the second traveling block 9 and the primary slide 4 (e.g., the connector 7 of the primary slide 4). In order to ensure smooth operation of the cord 2 and to save power of the rotary drive 13 under the same conditions, the first 203, second 204 and third 205 sub-cord segments may be arranged parallel to each other. Of course, the first, second and third sub-cord segments 203, 204 and 205 may also be angled with respect to each other.

It will be appreciated that, referring to fig. 5 to 7, a first guiding portion 501 and a second guiding portion 502 are disposed on a side of the intermediate rail 5 facing the primary rail 4, the first guiding portion 501 is slidably connected to the rail 301, the second guiding portion 502 is slidably connected to the primary rail 4, and the rail 301 and the primary rail 4 are juxtaposed on the intermediate rail 5. The first guide portion 501 and the second guide portion 502 are located on the same side of the intermediate slide rail 5, which helps to simplify the structure of the intermediate slide rail 5 and reduce the thickness of the linear transmission mechanism.

The first guide portion 501 is in guide engagement with the guide rail 301, the second guide portion 502 is in guide engagement with the primary slide rail 4, and the forms of the first guide portion 501 and the second guide portion 502 are not limited. For example, the guide rail 301 may include a guide groove, and the first guide portion 501 may be moved along the extending direction of the guide groove; alternatively, the guide rail 301 may include a guide protrusion, and the first guide part 501 may be moved along the extension direction of the guide protrusion. Likewise, the structural form of the second guide 502 and the primary slide rail 4 is not limited, as long as a guide fit can be formed. For example, the second guiding portion 502 and the primary sliding rail 4 may be matched through a protrusion and a groove, or a sliding member, such as a pulley, may be installed between the second guiding portion 502 and the primary sliding rail 4, so as to reduce friction resistance, and make the motion of the primary sliding rail 4 smoother.

As shown in fig. 6 and 7, the guide rail 301 is connected to the mounting member 3 through the fixing member 302, and the fixing member 302 is connected to the mounting member 3 through a fastener (such as a screw, a rivet, a nut, etc.), so that the mounting manner of the guide rail 301 is simple and convenient to disassemble and assemble. The guide rail 301 is covered on the outer side of the first guiding portion 501, and the guide rail 301 plays a role in protecting the first guiding portion 501, so that the structure of the linear transmission mechanism is simpler. The first-stage slide rail 4 is covered on the outer side of the second guiding part 502, and the first-stage slide rail 4 can play a role in protecting the second guiding part 502. The side surfaces of the guide rail 301 and the first-stage slide rail 4, which are opposite to the middle slide rail 5, are flat surfaces, and the surface of the mounting piece 3, which is opposite to the middle slide rail 5, is also flat surfaces, so that the appearance of the linear transmission mechanism is simpler, and the integrity is stronger.

As shown in fig. 3 and 5, the linear transmission mechanism is provided with the guard plate 11, and through the arrangement of the guard plate 11, when the sliding rail is in a contracted state, part or all of the pulleys are basically hidden by the guard plate 11, so that the function of protecting the pulleys is achieved, and the integrity of the linear transmission mechanism is also stronger.

In some cases, as shown in fig. 3, 5 and 6, the primary slide rail 4 is provided with a mounting portion 401, and the mounting portion 401 is connected to the drawer body 12. The connection mode of the mounting portion 401 and the drawer body 12 may be a detachable mode or a fixed mode, such as fastening connection, welding, etc., and may be specifically selected according to requirements.

The form of the guide rail 301 is not limited according to the embodiment of the present invention. When the primary slide rail 4 is directly mounted on the guide rail 301, the guide rail 301 only has to guide the primary slide rail 4. For example, the guide rail 301 may include a guide groove, and the primary slide rail 4 may be moved along the extending direction of the guide groove; alternatively, the guide rail 301 may include a guide projection, and the primary slide rail 4 may be moved along the extending direction of the guide projection. The guide rail 301 may be integrally formed with the mount 3, or may be a separate member fixed to the mount 3. Similarly, the structure of the primary slide rail 4 is not limited, so long as the primary slide rail 4 can form guiding fit with the guide rail 301, and further the primary slide rail 4 can move relative to the guide rail 301. For example, the primary slide rail 4 and the guide rail 301 may be engaged with each other by means of mating protrusions and grooves, or a sliding member such as a pulley may be installed between the primary slide rail 4 and the guide rail 301, and then the primary slide rail 4 and the guide rail 301 may be engaged with each other by means of the sliding member.

When the storage cabinet is a refrigerator, the drawer assembly is installed in the refrigerator, the drawer body 12 can be positioned at the bottom of a freezing compartment of the refrigerator, the space in the drawer body 12 can be a refrigerating compartment, a freezing compartment, a temperature changing compartment or other functional compartments, and the temperature range in the drawer body 12 can be set according to the setting.

In order to facilitate taking and placing of articles in the drawer body 12, the drawer body 12 is mounted on a container of the refrigerator through a linear transmission mechanism. In fig. 3 and 4, the linear transmission mechanism is located at the bottom of the drawer body 12, the rear end of the mounting member 3 is provided with the rotating wheel 1 and the rotation driving member 13, the primary sliding rail 4 is arranged above the intermediate sliding rail 5, the intermediate sliding rail 5 is arranged above the mounting member 3, and the connecting member 7 of the primary sliding rail 4 is connected with the drawer body 12. One or more sets of linear drives may be provided below the drawer body 12. The linear transmission mechanism only occupies the space on one side of the drawer body 12, the space occupied by the linear transmission mechanism is reduced, and the linear transmission mechanism can provide a larger space for the drawer body 12 in a locker with the same volume, thereby being beneficial to lifting the storage space of the locker.

Wherein, form the spout of middle slide rail 5 between guide rail 301 and the installed part 3, and then when middle slide rail 5 moves relative to installed part 3, can guarantee the structural strength and the stability of operation of middle slide rail 5.

When the sliding rail is in a contracted state, the drawer body 12 is retracted into the cabinet 14; when the slide rail is in the extended state, the drawer body 12 extends out of the cabinet 14, and the primary slide rail 4 and the intermediate slide rail 5 can be in respective limit positions, so that the drawer body 12 extends out by a maximum distance. Alternatively, only the primary slide rail 4 is in the extreme position, or alternatively, the primary slide rail 4 is only partially extended and the intermediate slide rail 5 is in the original position. The states of the primary slide rail 4 and the intermediate slide rail 5 can be selected according to the conditions, so that the position of the drawer body 12 can be adjusted.

In the case of a group of linear transmission mechanisms, the middle slide rail 5 is correspondingly arranged in the middle of the drawer body 12, so that the drawer body 12 is uniformly stressed. And the primary slide rail 4 is correspondingly arranged at the middle position of the drawer body 12.

It will be appreciated that as shown in fig. 3 to 6, the primary track 4 is provided with a connector 7, the connector 7 being fixed to the primary track 4 and adapted to move linearly along the intermediate track 5, and the connector 7 connecting the first 201 and second 202 cable segments. The fixing manner of the connecting piece 7, the first flexible cable segment 201 and the second flexible cable segment 202 is not limited, and for example, the connecting piece 7, the first flexible cable segment 201 and the second flexible cable segment 202 may be bound, or the connecting piece 7, the first flexible cable segment 201 and the second flexible cable segment 202 may also be welded. Wherein, the setting of connecting piece 7 can make things convenient for the assembly between one-level slide rail 4 and the middle slide rail 5 to can make things convenient for the setting of flexible cable 2. Of course, the connecting piece 7 may not be provided, and the first flexible cable segment 201 and the second flexible cable segment 202 may be directly connected to the primary slide rail 4.

Referring to fig. 3 and 4, the connecting member 7 is fixed to the rear end of the primary slide rail 4 along the extending direction of the primary slide rail 4 with respect to the mounting member 3. In this case, the travel of the primary slide rail 4 relative to the intermediate slide rail 5 can be ensured. Of course, the connecting piece 7 may be disposed at other positions of the primary slide rail 4 when the stroke of the primary slide rail 4 meets the requirement.

The rotating wheel 1 may be a synchronous pulley or a pulley, and the flexible cable 2 may be a belt or a flexible belt having a high friction coefficient. For example, the rotating wheel 1 may select a pulley and the flexible cord 2 selects a belt that mates with the pulley. The situation can ensure that the flexible rope 2 is driven to move when the rotating wheel 1 rotates, and the flexible rope 2 is prevented from slipping relative to the rotating wheel 1. Of course, the specific forms of the rotating wheel 1 and the flexible cable 2 are not limited, and only the rotating wheel 1 rotates to drive the flexible cable 2 to move. Likewise, the specific structure of the flexible cord 2 is not limited, and may be, for example, a wire rope.

The above-described rotation driving member 13 may be, but is not limited to, a motor (including a linear motor and a rotary motor), as long as the rotation driving member 13 can drive the rotary wheel 1 to rotate as a power source. For example, the rotary drive 13 may also be a pneumatic cylinder which can convert a linear motion into a rotation of the rotary wheel 1 via a rack and pinion pair. The rotary driving member 13 may also be a rotary handle, which can manually drive the rotary wheel 1 to rotate, so as to realize the sliding rail movement.

Based on the above embodiments, the linear drive mechanism will be further described with reference to fig. 1 to 7.

The linear drive mechanism comprises two states, namely a contracted state and an extended state. Wherein, the retracted state refers to the sliding rail being retracted towards the rear end relative to the guide rail 301, corresponding to fig. 3 and 6; the extended state refers to the slide rail extending forward relative to the guide rail 301, corresponding to fig. 5. Correspondingly, the drawer or receiving structure connected to the primary slide 4 has two positions, an extended position and a retracted position.

Referring to the state shown in fig. 3 to 5, when the rotary wheel 1 rotates in the forward direction, the second flexible cable section 202 between the rotary wheel 1 and the fixed pulley 6 winds the rotary wheel 1, and at the same time, the second flexible cable section 202 drives the fixed pulley 6, the first movable pulley 8 and the second movable pulley 9 to rotate; the first flexible cable section 201 is wound out of the rotating wheel 1, so that the primary slide rail 4 extends away from the rotating wheel 1. When the primary slide rail 4 moves to the limit position, if the rotating wheel 1 continues to rotate in the forward direction, the second flexible cable segment 202 continues to wind toward the rotating wheel 1, so as to drive the first movable pulley 8 to move in the direction in which the primary slide rail 4 moves out, i.e. the intermediate slide rail 5 extends out relative to the guide rail 301. In the process that the primary sliding rail 4 extends outwards, at the moment, a second flexible cable section 202 between the second movable pulley 9 and the connecting piece 7 is shortened, and a first flexible cable section 201 between the connecting piece 7 and the rotating wheel 1 is lengthened; during the outward extension of the intermediate slide 5, the second flexible cable segment 202 between the fixed pulley 6 and the first movable pulley 8 is shortened, and the first flexible cable segment 201 between the connecting piece 7 and the rotating wheel 1 is further lengthened.

Referring to fig. 5 to fig. 3, when the rotary wheel 1 rotates reversely, the second flexible cable section 202 between the rotary wheel 1 and the fixed pulley 6 winds out of the rotary wheel 1, and at the same time, the second flexible cable section 202 drives the fixed pulley 6, the first movable pulley 8 and the second movable pulley 9 to rotate; the first flexible cable section 201 is wound towards the rotating wheel 1 so that the primary slide rail 4 is retracted towards the rotating wheel 1. When the primary slide rail 4 moves to the limit position, if the rotating wheel 1 continues to rotate reversely, the first flexible cable segment 201 continues to wind around the rotating wheel 1, and the second flexible cable segment 202 continues to wind out of the rotating wheel 1, so that the intermediate slide rail 5 retracts towards the direction approaching to the rotating wheel 1. When the primary slide rail 4 retracts, the first flexible cable section 201 is shortened, and the second flexible cable section 202 is lengthened; when the intermediate slide 5 is retracted, the first flexible cable segment 201 becomes shorter and the second flexible cable segment 202 continues to become shorter.

The forward direction and the reverse direction are opposite directions, such as the forward direction is anticlockwise and the reverse direction is clockwise.

Referring to fig. 5, the fixed pulley 6 is disposed on the mount 3 corresponding to the front end of the guide rail 301, and the rotating wheel 1 is disposed on the mount 3 corresponding to the rear end of the guide rail 301. Under the condition that the mounting piece 3 is connected with the middle sliding rail 5, the middle sliding rail 5 is connected with a first movable pulley 8 and a second movable pulley 9, the rotating wheel 1 is arranged corresponding to the fixed pulley 6, the first movable pulley 8 and the second movable pulley 9, and the diameter of the rotating wheel 1 is larger than that of the fixed pulley 6, the first movable pulley 8 and the second movable pulley 9. Wherein, "the rotating wheel 1 is provided corresponding to the fixed pulley 6, the first movable pulley 8 and the second movable pulley 9" means that: the rotating wheel 1 is arranged along the front-back direction of the first movable pulley 8 and the second movable pulley 9, so that the smooth movement of the flexible cable 2 can be ensured. In addition, the diameter of the rotating wheel 1 is larger than that of the first movable pulley 8 and the second movable pulley 9, so that the sections of the flexible cable 2 positioned on two sides of the rotating wheel 1 can be tangent to the rotating wheel 1, and smooth operation of the flexible cable 2 is further guaranteed.

In the linear transmission mechanism in the embodiment, when the rotating wheel 1 rotates, the sliding rail can be driven to extend or retract, the rotary driving piece 13 is fixedly arranged at a fixed position, the rotary driving piece 13 does not need to move, a cable is not bent, the service life can be prolonged, the pulleys are arranged in a front-back staggered mode, the transmission efficiency is high, and the occupied space is small.

An embodiment of a second aspect of the present invention, as shown in connection with fig. 1-15, provides a locker comprising a cabinet and a drawer assembly as described above. The drawer assembly has the beneficial effects, and the storage cabinet has the beneficial effects, and specific reference can be made to the above, and details are not repeated here.

The linear transmission mechanism can drive the drawer body 12 to automatically move so as to take and put articles in the storage cabinet. In addition, the linear transmission mechanism occupies a small space and has a simple structure, and therefore, the linear transmission mechanism hardly occupies the space inside the cabinet 14 additionally. In addition, the drawer component is low in preparation cost and convenient to assemble and disassemble, and further has strong applicability, and can be applied to various products such as refrigerators, wardrobes, showcases and the like.

The mounting member 3 may be an independent component detachably mounted on the cabinet 14, and the mounting member 3 may be integrally formed on the cabinet 14.

According to the locker of the embodiment of the invention, the rotary wheel 1 and the rotary driving member 13 are installed at the inner side of the locker. Wherein, can produce certain noise when rotatory wheel 1 and rotary drive spare 13 move, through installing rotatory wheel 1 and rotary drive spare 13 in the inboard of locker, can reduce the noise of outgoing in the locker. The inner side of the locker refers to the side far away from the door body, and the side close to the door body refers to the outer side of the locker. In use, the "inside of the locker" is the side farther from the user. For example, in fig. 1, the rotary wheel 1 and the rotary driving member 13 are located at the rear side of the mounting member 3, so that noise of the locker in use can be reduced, and the door body of the locker is not affected in appearance when being opened.

According to the locker of the embodiment of the invention, the locker is a refrigerator, a retail cabinet or a showcase, and the specific form of the locker is not limited by the example. When the storage cabinet is a refrigerator, the refrigerator is often provided with the freezing drawer assembly at the bottom, and the problem that a user cannot conveniently draw the drawer body 12 and cannot conveniently take and put food from the freezing drawer assembly can be solved by the linear transmission mechanism.

According to embodiments of the present invention, automatic movement of the drawer assembly may be controlled by providing a corresponding switch or sensor. For example, a switch is provided in the drawer assembly or the locker, and the switch is pressed to control the movement (extension or retraction) of the primary slide rail 4. For another example, a sensor is arranged in the storage cabinet, and when the sensor senses corresponding actions, such as approaching of hands, a signal is generated to control the first-stage sliding rail 4 to extend or retract, and further control the drawer body 12 to extend or retract, or control the shelf to lift.

Taking a refrigerator as an example, an inductor can be arranged at a corresponding position of the refrigerator, and when corresponding operation is continuously sensed, the rotary driving piece 13 continuously acts, so that the drawer body 12 or the shelf of the refrigerator gradually moves forward. When the corresponding operation is lost, the rotary drive 13 is no longer active, and the drawer body 12 or the shelf is stopped in the current position. For example, a pressing sensor is disposed on the drawer body 12, the door body or the container, and the rotary driving member 13 continuously drives the rotary wheel 1 to rotate when being pressed, so as to drive the drawer body 12 or the shelf to move reversely. For another example, the pressing sensor may be replaced with an infrared sensor or other type of sensor. When the drawer body 12 or the shelf is required to be lowered, continuous sensing is not required, and only one operation is required to realize the reverse movement of the drawer body 12 or the shelf. Of course, the rotary driving member 13 may also be controlled based on an acoustic signal, for example, based on acoustic information such as "extending the drawer" or "retracting the drawer", and the state switching of the drawer body 12 may be achieved.

The motion control of the linear transmission mechanism can also be realized through other signal inputs. For example, the locker may be adapted to a corresponding remote control comprising operating buttons for extension or retraction. Further, the telescoping control of the first-stage slide rail 4 can be realized based on the buttons of the remote controller. Or, corresponding buttons can be arranged on the door body of the storage cabinet, so that the drawer assembly can be controlled to move before the door is opened. For another example, the control of the drawer assembly of the refrigerator can also be realized through the mobile phone APP.
