[0073] like Figure 1 and Figure 2 As shown, some embodiments provide a drawer assembly, which includes a drawer frame 200 , a drawer 300 and a rebound assembly 100 .

[0074] The drawer 300 is disposed in the drawer frame 200. Figure 3a and Figure 3b As shown, the side wall of the drawer 300 is provided with a guide groove 301 .

[0075] The drawer 300 is configured to be pulled out from the drawer frame 200 and positioned at the first limit position. The drawer 300 is positioned at the first limit position, indicating that the drawer 300 is pulled out of the drawer frame 200 to the maximum extent under normal conditions. If the drawer 300 is pulled further, it will cause an abnormal state such as the drawer 300 falling off from the drawer frame 200. The drawer 300 is configured to be pushed back into the drawer frame 200 and positioned at the second limit position. The drawer 300 is positioned at the second limit position, indicating that the drawer 300 is returned to the drawer frame 200 to the maximum extent under normal conditions.

[0076] like Figure 1 and Figure 2 As shown, the rebound assembly 100 is fixedly disposed in the drawer frame 200 and is located on the side of the drawer 300. Figure 4 As shown, the rebound assembly 100 includes a frame 1, a slider 2, an elastic member 3 and a guide member 4.

[0077] The frame body 1 is provided with a first sliding hole 11 .

[0078] The slider 2 is movably disposed in the frame 1 , and a second sliding hole 21 is disposed on the slider 2 .

[0079] The elastic member 3 is disposed in the frame 1 and connects the slider 2 and the inner wall of the frame 1 .

[0080] The guide member 4 is movably disposed on the frame 1 , and a first end of the guide member 4 passes through the first sliding hole 11 and the second sliding hole 21 and extends into the guide groove 301 .

[0081] The guide groove 301 is configured to drive the guide member 4 to move along the first sliding hole 11 when the drawer 300 is pulled toward the outside of the drawer frame 200, thereby driving the slider 2 to move and stretching the elastic member 3. Figure 8a , Figure 8b and Figure 8c .

[0082] The guide groove 301 is also configured so that when the slider 2 moves under the restoring force of the elastic member 3 and drives the guide member 4 to move along the first slide hole 11, the guide groove 301 cooperates with the guide member 4 to drive the drawer 300 to move into the drawer frame 200. Figure 8a , Figure 8b and Figure 8c .

[0083] In the above embodiment, the resilient assembly 100 is fixedly installed inside the drawer frame 200, and the first end of the guide member 4 in the resilient assembly 100 extends into the guide groove 301 and cooperates with the guide groove 301. When the drawer 300 is pulled to the outside of the drawer frame 200, the guide groove 301 on the side wall of the drawer 300 cooperates with the guide member 4 of the resilient assembly 100, driving the guide member 4 to move along the first sliding hole 11 in the frame 1. Since the first end of the guide member 4 also passes through the second sliding hole 21 of the slider 2, the guide member 4 also drives the slider 2 to move when it moves, and the slider 2 moves to stretch the elastic member 3. When the drawer 300 needs to be pushed back into the drawer frame 200, since the force for pulling the drawer 300 outward is no longer applied, the elastic restoring force of the elastic member 3 pulls the slider 2 to move, and the slider 2 drives the guide member 4 to move along the first sliding hole 11. The guide member 4 cooperates with the guide groove 301, pulls the guide groove 301, and then drives the drawer 300 to move into the drawer frame 200. Therefore, when the drawer 300 returns to the drawer frame 200, the drawer 300 can be returned only by the elastic restoring force of the elastic member 3, thereby realizing automatic rebound of the drawer. The rebound component 100 runs smoothly without strong collision and with low noise.

[0084] The rebound assembly 100 includes a frame 1, a slider 2, an elastic member 3 and a guide member 4. The slider 2 is movably disposed in the frame, the elastic member 3 connects the slider 2 and the frame 1, and the first end of the guide member 4 passes through the first sliding hole 11 on the frame 1 and the second sliding hole 21 on the slider 2 in sequence, and can be matched with the guide groove 301 on the drawer 300. The rebound assembly 100 has a simple structure and is easy to install. The frame 1 of the rebound assembly 100 can be fixedly installed in the drawer frame 200, for example, fixed in the drawer frame 200 by screws 6. The rebound assembly 100 is easy to install, and the drawer 300 does not need to be provided with a complex structure to cooperate with the rebound assembly 100, and only needs to be provided with a guide groove 301. Therefore, the drawer assembly has a simple structure as a whole and is easy to install.

[0085] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the rebound assembly 100 also includes a protective cover 5, which is disposed on the frame 1 to cover the slider 2 and the elastic member 3 in the frame 1, and the protective cover 5 is provided with a third sliding hole 51, and the third sliding hole 51 is parallel to the first sliding hole 11, and the first end of the guide member 4 passes through the first sliding hole 11, the second sliding hole 21 and the third sliding hole 51 in sequence and extends into the guide groove 301.

[0086] The shape of the third sliding hole 51 is the same as or similar to that of the first sliding hole 11 , and the third sliding hole 51 will not restrict the free movement of the guide member 4 along the first sliding hole 11 .

[0087] In the above embodiment, the rebound component 100 is combined with the frame body 1 and the protective cover 5 to form a box body, the slider 2 and the elastic member 3 are arranged in the box body, and the guide member 4 is movably arranged in the frame body. The first end of the guide member 4 sequentially passes through the first sliding hole 11 on the frame body 1, the second sliding hole 21 on the slider 2 and the third sliding hole 51 on the protective cover 5 to extend into the guide groove 301, and cooperates with the guide groove 301. The structure of the rebound component 100 is simple, and the rebound component 100, that is, the above-mentioned integrated box body, can be directly fixed inside the drawer frame 200 to complete the installation. For example: by Figure 4 The screw 6 shown in the figure can be used to fix the rebound component 100 in the drawer frame 200, which is easy to install. The drawer 300 does not need to be provided with a complex structure to cooperate with the rebound component 100, and only needs to be provided with a guide groove 301.

[0088] like Figure 7 , Figure 8a and Figure 8cAs shown, in some embodiments, the first sliding hole 11 includes a first hole segment 111 and a second hole segment 112, the first hole segment 111 extends along the push-pull movement direction of the drawer 300, the second hole segment 112 is connected to the first end of the first hole segment 111, and the second hole segment 112 extends upward from the first hole segment 111; the guide groove 301 is configured to make the guide member 4 located in the second hole segment 112 when the drawer 300 is located at the first limit position, as shown in FIG. Figure 8b As shown, at this time, the elastic member 3 is stretched to the maximum length. Due to the restriction of the hole wall of the second hole section 112 on the guide member 4, the slider 2 cannot be pulled even if the elastic member 3 provides elastic restoring force.

[0089] In some embodiments, the guide groove 301 is further configured to push the guide member 4 to move from the second hole section 112 to the first hole section 111 when the drawer 300 is forced to move from the first limit position into the drawer frame 200. At this time, the drawer 300 is no longer pushed to move into the drawer frame 200, and the elastic restoring force provided by the elastic member 3 pulls the slider 2 to move along the first hole section 111, and the slider 2 drives the guide member 4 to move along the first hole section 111, and then the guide member 4 cooperates with the guide groove 301, so that the drawer 300 moves to the inside of the drawer frame 200 by itself under the elastic restoring force of the elastic member 3.

[0090] like Figure 8a As shown, when the drawer 300 is located in the second limit position in the drawer frame 200, the guide member 4 is located in the first hole section 111. When the drawer 300 moves from the second limit position to the first limit position, that is, when the drawer 300 moves out of the drawer frame 200, the guide groove 301 of the side wall of the drawer 300 cooperates with the guide member 4 in the rebound assembly 100, driving the guide member 4 to move along the first hole section 111. The first end of the guide member 4 is penetrated by the second sliding hole 21 of the slider 2. Therefore, the guide member 4 drives the slider 2 to move along the first hole section 111, and the slider 2 stretches the elastic member 3.

[0091] like Figure 8b As shown, when the drawer 300 is about to reach the first limit position, the guide member 4 is located at the first end of the first hole segment 111, and the drawer 300 continues to be pulled outward. The guide groove 301 pushes the guide member 4 to move toward the second hole segment 112. When the drawer 300 reaches the first limit position, the guide member 4 is located in the second hole segment 112, and the elastic member 3 is stretched to the maximum length. Due to the restriction of the hole wall of the second hole segment 112 on the guide member 4, even if the elastic member 3 provides elastic restoring force, it cannot pull the slider 2.

[0092] like Figure 8cAs shown, when the drawer 300 is used and needs to be retracted into the drawer frame 200, the drawer 300 is pushed into the drawer frame 200, and the guide groove 301 pushes the guide member 4 from the second hole section 112 to the first hole section 111. At this time, the drawer 300 is no longer pushed to move toward the inside of the drawer frame 200. The restoring force provided by the elastic member 3 pulls the slider 2 to move along the first hole section 111, and the slider 2 drives the guide member 4 to move along the first hole section 111, and then the guide member 4 cooperates with the guide groove 301, so that the drawer 300 moves toward the inside of the drawer frame 200 by itself under the elastic restoring force of the elastic member 3.

[0093] Therefore, after the drawer 300 is used, it only needs to be pushed back into the drawer frame 200 to move the guide member 4 from the second hole section 112 to the first hole section 111, so that the drawer 300 can automatically rebound and reset, greatly improving the user experience.

[0094] like Fig. 9 and Fig.10 As shown, in some embodiments, the second slide hole 21 extends in the up-down direction of the first hole segment 111. The guide member 4 can move up and down along the second slide hole 21. When the guide member 4 moves from the first hole segment 111 to the second hole segment 112, it also moves up along the second slide hole 21. When the guide member 4 moves from the second hole segment 112 to the first hole segment 111, it also moves down along the second slide hole 21.

[0095] like Figure 7 , Figure 8a , Figure 8b and Figure 8c As shown, in some embodiments, the frame 1 is provided with a slide 12 extending along the push-pull movement direction of the drawer 300, and the first slide hole 11 is provided on the slide 12. Fig.10 As shown, the slider 2 is provided with a clamping structure 22 , and the slider 2 is clamped to the slideway 12 via the clamping structure 22 , and is movably arranged relative to the slideway 12 .

[0096] like Fig.11 As shown, the guide member 4 includes a guide column 43 , and a first limit block 41 and a second limit block 42 arranged on the guide column 43 .

[0097] As shown in FIG. 12 , the first limit block 41 is located outside the frame 1. Figure 8a , Figure 8b and Figure 8c The second limit block 42 is arranged on the inner side of the frame 1. As shown in reference 11, the radial dimension of the first limit block 41 is larger than the radial dimension of the first sliding hole 11, the radial dimension of the second limit block 42 is larger than the radial dimension of the first sliding hole 11, and the guide column 43 passes through the first sliding hole 11 and the second sliding hole 21 and extends into the guide groove 301.

[0098] Specifically, the first limit block 41 and the second limit block 42 are arranged at the second end of the guide column 43 , and the first end of the guide column 43 , that is, the first end of the guide member 4 , passes through the first sliding hole 11 and the second sliding hole 21 and extends into the guide groove 301 .

[0099] The installation method of the guide member 4 can be: first set the first limit block 41 on the guide column 43, set the first limit block 41 on the outside of the frame 1, the guide column 43 passes through the first sliding hole 11, and then set the second limit block 42 on the guide column 43, and the guide member 4 is movably set on the frame 1 through the cooperation of the first limit block 41 and the second limit block 42.

[0100] Of course, the guide member 4 can also be installed by setting a mounting hole 13 on the frame 1.

[0101] In some embodiments, Figure 7 , Fig.12 and Fig.13 As shown, the direction from the first end to the second end of the first sliding hole 11 is consistent with the direction in which the drawer 300 is pushed back into the frame 1. A mounting hole 13 is also provided on the frame 1. The mounting hole 13 is connected to the second end of the first sliding hole 11. The radial dimension of the mounting hole 13 is larger than the radial dimension of the first sliding hole 11. The radial dimension of the first limiting block 41 is larger than the radial dimension of the mounting hole 13. The radial dimension of the second limiting block 42 is smaller than the radial dimension of the mounting hole 13. The guide member 4 is configured to be installed from the mounting hole 13 to the frame 1 and moved to the first sliding hole 11.

[0102] The installation process of the guide member 4 is as follows: the first limit block 41 and the second limit block 42 are arranged at the second end of the guide column 43, and the second limit block 42 of the guide member 4 is passed through the mounting hole 13 from the outside of the frame 1. Since the radial dimension of the first limit block 41 is larger than the radial dimension of the mounting hole 13, the first limit block 41 is located outside the frame 1, and then the guide member 4 is moved so that the guide member 4 is located in the first sliding hole 11.

[0103] In some embodiments, the first limit block 41 and the second limit block 42 may be oval. The frame 1 is sandwiched between the first limit block 41 and the second limit block 42 and moves along the first sliding hole 11 .

[0104] like Fig.12 , Fig.13 and Fig.14 As shown, in some embodiments, an avoidance hole 14 is further provided on the frame 1, and the avoidance hole 14 is adjacent to the second end of the first hole segment 111, and shares a section of rib 15 with the first hole segment 111, and the end of the rib 15 connected to the mounting hole 13 is disconnected to form a gap 16, and the gap 16 connects the avoidance hole 14, the mounting hole 13 and the first hole segment 111.

[0105] The rib 15 is provided with a protrusion 17 protruding toward the outside of the frame 1 . When the guide member 4 is installed, the rib 15 is pushed by the guide member 4 to deform and tilt toward the avoidance hole 14 , so that the guide member 4 passes over the protrusion 17 and moves to the first hole section 111 .

[0106] The rib 15 is also configured to restore its deformation after the guide member 4 moves to the first hole section 111 ; when the drawer 300 is located at the second limit position, the protrusion 17 abuts against the first limit block 41 to prevent the guide member 4 from entering the installation hole 13 .

[0107] Since a protrusion 17 protruding toward the outside of the frame 1 is provided on the rib 15 near the notch 16, when the guide member 4 is installed, the protrusion 17 will interfere with the first limit block 41. Therefore, when the guide member 4 is installed in the mounting hole 13, the rib 15 is pushed by the guide member 4 to deform and tilt toward the avoidance hole 14, so that the protrusion 17 will not interfere with the first limit block 41. Then, the guide member 4 is moved to move the guide member 4 into the first sliding hole 11 to avoid the protrusion 17. The thrust of the guide member 4 on the rib 15 disappears, and the rib 15 recovers its deformation and resets. At this time, when the guide member 4 moves toward the mounting hole 13, the protrusion 17 will interfere with the first limit block 41 again, abutting against the first limit block 41 to prevent the guide member 4 from moving into the mounting hole 13 and causing the guide member 4 to fall off from the frame 1.

[0108] In some embodiments, the first sliding hole 11 includes a first hole segment 111 and a second hole segment 112, the first hole segment 111 extends along the push-pull movement direction of the drawer 300, the second hole segment 112 is connected to the first end of the first hole segment 111, and the second hole segment 112 extends upward from the first hole segment 111; the guide groove 301 is configured to make the guide member 4 located in the second hole segment 112 when the drawer 300 is pulled out of the drawer frame 200 and is located at the first limit position;

[0109] When the guide member 4 fails and falls from the second hole segment 112 to the first hole segment 111, and the slider 2 is pulled to the second end of the first hole segment 111 by the elastic restoring force of the elastic member 3, the guide member 4 and the guide groove 301 are in an abnormal matching relationship. The guide groove 301 is also configured to push the guide member 4 to squeeze the rib 15 during the process of pushing the drawer 300 back, so that the rib 15 is deformed and tilted toward the avoidance hole 14. When the drawer 300 continues to be pushed back, the guide member 4 is no longer pushed to squeeze the rib 15, so that the guide member 4 recovers the normal matching relationship with the guide groove 301.

[0110] When the guide member 4 and the guide groove 301 are in an abnormal matching relationship, the drawer 300 can be pushed back, and the guide groove 301 on the side wall of the drawer 300 squeezes and pushes the guide member 4, and the guide member 4 squeezes and pushes the rib 15, causing the rib 15 to deform and tilt toward the avoidance hole 14. Then, the drawer 300 is pushed back further, and the pushing and squeezing force of the guide groove 301 on the guide member 4 disappears, the rib 15 is reset, the guide member 4 is reset, and the guide member 4 resumes the normal matching relationship with the guide groove 301.

[0111] like Fig.15 As shown, in some embodiments, a stopper 52 is disposed inside the protective cover 5, and after the guide member 4 is installed through the mounting hole 13, the end of the slider 2 abuts against the stopper 52 to prevent the slider 2 from moving toward the mounting hole 13. That is, after the guide member 4 is installed through the mounting hole 13, the first stopper 41 of the guide member 4 abuts against the protrusion 17, and the slider 2 abuts against the stopper 52, both of which can prevent the guide member 4 from moving into the mounting hole 13, thereby improving reliability.

[0112] like Figure 3a and Figure 3b As shown, in some embodiments, the guide groove 301 includes an arc segment 3013 , a first straight segment 3011 and a second straight segment 3012 .

[0113] The arc segment 3013 opens in the return direction of the drawer 300 back into the drawer frame 200. The first straight segment 3011 is located above the second straight segment 3012. The first straight segment 3011 connects the first open end of the arc segment 3013 and gradually extends obliquely toward the upper side of the drawer 300. The second straight segment 3012 connects the second open end of the arc segment 3013 and gradually extends obliquely toward the upper side of the drawer 300.

[0114] A convex portion 3014 is formed at a connection between the second straight segment 3012 and the second open end of the arc segment 3013 . The convex portion 3014 protrudes toward between the first straight segment 3011 and the second straight segment 3012 .

[0115] The protrusion 3014 is configured to push the guide member 4 to move when the drawer 300 is pulled outward, and the protrusion 3014 is also configured to abut the guide member 4 when the drawer 300 is moved inward.

[0116] Therefore, when the drawer 300 is pulled outside the drawer frame 200, the guide groove 301 cooperates with the guide member 4 to drive the guide member 4 to move along the first sliding hole 11, thereby driving the slider 2 to move and stretching the elastic member 3. When the slider 2 moves under the restoring force of the elastic member 3 and drives the guide member 4 to move along the first sliding hole 11, the guide groove 301 cooperates with the guide member 4 to drive the drawer 300 to move into the drawer frame 200.

[0117] In some embodiments, when the drawer 300 is located at the first limit position, the first end of the guide member 4 is located at one end of the first straight line segment 3011 away from the arc segment 3013, and when the drawer 300 is located at the second limit position, the first end of the guide member 4 is located between the arc segment 3013 and the protrusion 3014.

[0118] As in the above embodiment, the first sliding hole 11 includes a first hole segment 111 and a second hole segment 112. The first hole segment 111 extends along the push-pull movement direction of the drawer 300. The direction from the first end to the second end of the first hole segment 111 is consistent with the movement direction of the drawer 300 returning to the drawer frame 200. The second hole segment 112 is connected to the first end of the first hole segment 111, and the second hole segment 112 extends upward from the first hole segment 111.

[0119] In some embodiments, when the guide member 4 is located in the first hole segment 111 , the first end of the guide member 4 is located between the arc segment 3013 and the protrusion 3014 .

[0120] In some embodiments, the second straight line segment 3012 is configured to push the guide member 4 to move to the second hole segment 112 when the guide member 4 is located at the first end of the first hole segment 111 and the drawer 300 continues to be pulled, so that the first end of the guide member 4 is located at one end of the first straight line segment 3011 away from the arc segment 3013.

[0121] Since the second straight line segment 3012 is connected to the second open end of the arc segment 3013 and gradually extends obliquely upward toward the drawer 300, when the drawer 300 is pulled outward and the guide member 4 is driven to move to the first end of the first hole segment 111, the drawer 300 continues to be pulled, and the second straight line segment 3012 gradually extending obliquely upward toward the drawer 300 will squeeze and push the guide member 4 to move upward, so that the guide member 4 moves into the second hole segment 112.

[0122] In some embodiments, the first straight line segment 3011 is configured to push the guide member 4 from the second hole segment 112 to the first hole segment 111 when the drawer 300 is forced to move from the first limit position into the drawer frame 200, so that the first end of the guide member 4 is located between the arc segment 3013 and the protrusion 3014.

[0123] Since the first straight line segment 3011 is connected to the first open end of the arc segment 3013 and gradually extends obliquely upward toward the drawer 300, when the drawer 300 is pushed back inward, the first straight line segment 3011 gradually squeezes and pushes the guide member 4 downward as the drawer 300 moves, causing the guide member 4 to move from the second hole segment 112 to the first hole segment 111. At this time, the first end of the guide member 4 is located between the arc segment 3013 and the protrusion 3014.

[0124] In some embodiments, the guide groove 301 includes a third straight line segment 3015 , which connects the end of the second straight line segment 3012 away from the arc segment 3013 and gradually extends obliquely toward the bottom of the drawer 300 .

[0125] When the guide member 4 fails and falls from the second hole segment 112 to the first hole segment 111, and the slider 2 is pulled to the second end of the first hole segment 111 by the elastic restoring force of the elastic member 3, the first end of the guide member 4 is located at the third straight line segment 3015. At this time, the guide member 4 and the guide groove 301 are in an abnormal matching relationship.

[0126] When the guide member 4 and the guide groove 301 are in an abnormal matching relationship, the drawer 300 can be pushed back, and the third straight line segment 3015 pushes and squeezes the guide member 4 upward so that the first end of the guide member 4 is located in the second straight line segment 3012. The drawer 300 is pushed back continuously so that the guide member 4 moves downward along the second straight line segment 3012 to between the arc segment 3013 and the protrusion 3014. At this time, the guide member 4 is reset, and the guide member 4 and the guide groove 301 are in a normal matching relationship.

[0127] like Figure 8a , Figure 8b and Figure 8c As shown, in some embodiments, the elastic member 3 includes a first elastic member 31 and a second elastic member 32, the first elastic member 31 connects the upper part of the slider 2 and the upper part of the inner wall of the frame 1, and the second elastic member 32 connects the lower part of the slider 2 and the lower part of the inner wall of the frame 1.

[0128] like Figure 7 As shown, the frame 1 is provided with a first slot 18 for connecting the elastic member 3. Fig. 9 and Fig.10 As shown, the slider 2 is provided with a second slot 23 connected to the elastic member 3. The two ends of the elastic member 3 are narrow ends, which can be inserted into the first slot 18 and the second slot 23 respectively. Since both ends of the elastic member 3 are inserted into the slots, the slider 2 has a reset function under the elastic restoring force of the elastic member 3.

[0129] Of course, both ends of the elastic member 3 can also be hooked to the frame 1 and the slider 2 through hooks.

[0130] In some embodiments, a rubber block may be disposed in the middle of the elastic member 3 to alleviate the noise of the elastic member 3 .

[0131] Optionally, the elastic member 3 includes a spring.

[0132] In some embodiments, a rubber block may be disposed between the slider 2 and the protective cover 5 to reduce noise during collision.

[0133] Combine the following Figure 4Describe the assembly process of the resilient assembly 100 provided in some embodiments of the present disclosure:

[0134] The first limit block 41 and the second limit block 42 are arranged at the second end of the guide column 43. The second limit block 42 of the guide member 4 is passed through the mounting hole 13 from the outside of the frame 1 and is located on the inside of the frame 1. Since the radial dimension of the first limit block 41 is larger than the radial dimension of the mounting hole 13, the first limit block 41 is located on the outside of the frame 1. Since a protrusion 17 protruding toward the outside of the frame 1 is provided at a position close to the notch 16 on the rib 15, the protrusion 17 will interfere with the first limit block 41, so , the guide member 4 pushes the rib 15 to deform and tilt toward the avoidance hole 14, so that the protrusion 17 will not interfere with the first limit block 41, and then, the guide member 4 is moved to move the guide member 4 into the first sliding hole 11 to avoid the protrusion 17, and the thrust of the guide member 4 on the rib 15 disappears, and the rib 15 recovers its deformation and resets. At this time, when the guide member 4 moves toward the mounting hole 13, the protrusion 17 will interfere with the first limit block 41 again, abutting against the first limit block 41 to prevent the guide member 4 from moving into the mounting hole 13.

[0135] After the guide member 4 is installed, the first limit block 41 is located on the outside of the frame 1, and the second limit block 42 is located on the inside of the frame 1, and then the slider 2 is installed, and the second end of the guide post 43 on the guide member 4 passes through the second slide hole 21 on the slider 2. One end of the elastic member 3 is connected to the slider 2, and the other end is connected to the inner wall of the frame 1.

[0136] Then, the protective cover 5 is buckled on the frame 1, and the slider 2 and the elastic member 3 are placed in the frame 1. The first end of the guide post 43 passes through the third slide hole 51 on the protective cover 5. Fig.15 ), after the guide member 4 is installed through the mounting hole 13, the end of the slider 2 abuts against the stopper 52 to prevent the slider 2 from moving toward the mounting hole 13. That is, after the guide member 4 is installed through the mounting hole 13, the first stopper 41 of the guide member 4 abuts against the protrusion 17, and the slider 2 abuts against the stopper 52, both of which can prevent the guide member 4 from moving into the mounting hole 13, thereby improving reliability.

[0137] The installed rebound assembly 100 is installed into the drawer frame 200 by screws or other connecting parts, and the first end of the guide column 43 extends into the guide groove 301 set on the side wall of the drawer 300. The guide column 43 cooperates with the guide groove 301 to realize the rebound of the drawer 300.

[0138] The following is combined with Figure 3a and Figure 3b , and attached Figure 8a , Figure 8b and Figure 8cetc. describe some embodiments, in the process of pushing and pulling the drawer 300, the matching state of the guide column 43 and the guide groove 301.

[0139] When the user uses the drawer 300, an outward pulling force is provided to the drawer 300. At this time, the first end of the guide column 43 is located between the arc segment 3013 and the protrusion 3014 of the guide groove 301, and the guide groove 301 drives the guide column 43 to move along the first hole segment 111. When the guide column 43 moves to the first end of the first hole segment 111, the drawer 300 continues to be pulled outward, and the first straight segment 3011 of the guide groove 301 pushes the guide member 4 to move toward the second hole segment 112. When the guide member 4 is located in the second hole segment 112, the drawer 300 reaches the first limit position, and the elastic member 3 is stretched to the maximum length. Due to the restriction of the hole wall of the second hole segment 112 on the guide member 4, even if the elastic member 3 provides elastic restoring force, the slider 2 cannot be pulled. At this time, the first end of the guide member 4 is located at the end of the first straight segment 3011 away from the arc segment 3013.

[0140] After taking out the items in the drawer 300, the drawer 300 is pushed back into the drawer frame 200. The first straight line segment 3011 gradually presses and pushes the guide member 4 downward, so that the guide member 4 moves from the second hole segment 112 to the first hole segment 111, and the first end of the guide column 43 is located between the arc segment 3013 and the convex portion 3014. At this time, the slider 2 moves under the restoring force of the elastic member 3, driving the guide member 4 to move along the first slide hole 11. Since the first end of the guide column 43 is located between the arc segment 3013 and the convex portion 3014, the guide column 43 drives the drawer 300 to move into the drawer frame 200 through the guide groove 301, and the automatic rebound reset of the drawer 300 can be realized, which greatly improves the user experience. Finally, the drawer 300 is pulled into the drawer frame 200 and is located at the second limit position, completing the drawer extraction and automatic reset function.

[0141] When the drawer 300 is in the first limit position, under certain special circumstances, such as severe vibration, the guide post 43 may fall from the second hole segment 112 to the first hole segment 111. The impact force of the guide post 43 falling and the elastic restoring force of the elastic member 3 may work together to cause the slider 2 and the guide member 4 to quickly slide along the first hole segment 111 to the second end of the first hole segment 111, so that the first end of the guide post 43 overcomes the restriction of the protrusion 3014 and moves from the second straight segment 3012 to the third straight segment 3015. At this time, the drawer 300 is still in the first limit position, and the guide member 4 and the guide groove 301 are in an abnormal matching relationship.

[0142] In the above situation, the drawer 300 can be pushed back, and the third straight line segment 3015 pushes the extruded guide member 4 upward so that the first end of the guide member 4 is located in the second straight line segment 3012. In this process, the guide member 4 squeezes and pushes the rib 15, causing the rib 15 to deform and tilt toward the avoidance hole 14. The drawer 300 is pushed back continuously so that the guide member 4 moves downward along the second straight line segment 3012 to between the arc segment 3013 and the convex portion 3014. At this time, the guide member 4 no longer squeezes and pushes the rib 15, and the rib 15 recovers its deformation and resets. The guide member 4 also recovers its normal matching relationship with the guide groove 301, completing the reset of the guide member 4 after failure.

[0143] like Figure 1 and Figure 2 As shown, in some embodiments, the drawer assembly further includes a cover plate 400 , which is disposed on the drawer frame 200 and located above the drawer 300 .

[0144] Some embodiments further provide a refrigerator comprising the above-mentioned drawer assembly.

[0145] Based on the above-mentioned embodiments of the present invention, unless explicitly denied, the technical features of one embodiment may be beneficially combined with one or more other embodiments.

It should be understood by those skilled in the art that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present invention.
