A mechanism with a bounce function

Abstract

The mechanism with rebound function forms the buffering effect when the drawer moves from the second position to the first position through the conversion of energy. The first buffering assembly and the elastic buffering assembly are matched to make the pushing mechanism move smoothly, so as to avoid the collision of the articles in the drawer in the rapid movement of the drawer and the sound emission. In the process that the pushing mechanism moves from the first position to the second position, when the matching part and the first trigger part abut in the second position, the kinetic energy on the pushing mechanism is converted into the elastic potential energy when the reset housing retracts in the process that the first buffering assembly and the elastic buffering assembly abut, the reset housing drives the hinged housing to rotate relative to the first rebound housing when the reset housing retracts, the buffering assembly forms the buffering effect when the drawer moves from the first position to the second position through the conversion of energy, so that the pushing mechanism moves stably when the drawer is converted from the opening state to the closing state.

Description

Technical Field

[0001] This invention relates to the field of furniture technology, specifically to a mechanism with a rebound function. Background Technology

[0002] Currently, people have increasingly higher requirements for the user experience of furniture, especially for furniture used for storage, such as drawer cabinets. These drawer cabinets are typically connected to the cabinet body via smooth-sliding drawer slides, allowing the drawers to fit snugly against the furniture when closed, resulting in a neat and aesthetically pleasing appearance.

[0003] For example, Chinese patent document CN109645722A discloses a drawer slide push-to-rebound device. This push-to-rebound device can achieve a rebound function, causing the drawer to pop out automatically. However, this drawer slide push-to-rebound device lacks a buffer mechanism. When the drawer pops out and closes, due to excessive pushing or popping force, without a buffering effect, items inside the drawer are prone to shifting rapidly and producing impact noise. Therefore, a mechanism needs to be designed to solve the above problems. Summary of the Invention

[0004] To address the aforementioned technical problem of existing drawers lacking a buffering effect when popping out and closing, the technical solution adopted by this invention is as follows:

[0005] A mechanism with a rebound function includes a housing, a buffer assembly, and a push mechanism for connecting to a drawer and being movable relative to the housing to open or close the drawer. The housing is provided with a rebound mechanism, a first trigger part, and a locking mechanism.

[0006] The rebound mechanism is movable relative to the housing, and a reset component is provided between the rebound mechanism and the housing to reset the rebound mechanism to a first position; the rebound mechanism can move to a second position when the drawer is closed;

[0007] The buffer assembly includes at least one first buffer assembly disposed on the pushing mechanism, and a retractable elastic buffer assembly disposed on the rebound mechanism.

[0008] The rebound mechanism includes a first rebound housing, the first rebound housing having a first receiving cavity, and the elastic buffer assembly including a hinged housing with one end hinged in the first receiving cavity, an elastic reset part connected to the hinged housing and extending out of the outer side of the housing, and a first elastic block with one end abutting against the hinged housing.

[0009] The locking mechanism is used to lock the rebound mechanism in the second position;

[0010] When the rebound mechanism moves to the point where the first elastic block contacts the first triggering part, the first triggering part causes the first elastic block to move relative to the hinge housing and make way, so that the hinge housing can rotate relative to the rebound mechanism along the hinge point, so that the elastic reset part retracts into the housing;

[0011] After the locking mechanism is unlocked, the rebound mechanism is reset to the first position under the action of the reset component, and drives the pushing mechanism to move to open the drawer. During the process of the pushing mechanism moving to open the drawer, the first buffer component contacts the elastic reset part and causes the elastic reset part to retract.

[0012] In order to improve the effect of the elastic reset part reciprocating between the outside and inside of the clearance opening, the first accommodating cavity is provided with a clearance opening for the elastic reset part to retract. When the first rebound housing is in the first position, the hinged housing abuts against the side of the first elastic block.

[0013] In the second position, in order to improve the effect of the elastic reset part reciprocating between the outside and inside of the clearance opening, the first elastic block includes a mating part, a connecting post connected to the mating part, and a first elastic part with one end abutting against the connecting post and the other end abutting against the first rebound housing. When the mating part abuts against the first trigger part in the second position, the hinge housing can rotate relative to the first rebound housing. The first rebound housing is provided with a first guide groove, and the hinge housing is provided with a protrusion facing the outside of the first guide groove.

[0014] When in the first position, in order to improve the effect of the elastic reset part reciprocating between the outside and inside of the clearance opening, the hinge housing is provided with a hinge housing mounting cavity and a hinge housing opening communicating with the hinge housing mounting cavity. The elastic reset part includes a reset housing disposed on the hinge housing mounting cavity and passing through the hinge housing opening, and a reset housing elastic member connected to the reset housing at one end. The other end of the reset housing elastic member abuts against the hinge housing mounting cavity. The reset housing is provided with a buffer block that contacts the first buffer assembly.

[0015] To improve the reset effect of the reset assembly, the pushing mechanism is provided with a pushing block, the rebound mechanism is provided with a sliding member that abuts against the pushing block, and a second rebound housing that is connected to the sliding member on one side and connected to the first rebound housing. The reset assembly includes an adjustment device fixedly disposed at one end of the housing, and a reset elastic member disposed on the second rebound housing and connected to the adjustment device.

[0016] To improve the cooperation effect between the first rebound housing and the second rebound housing, the second rebound housing is provided with a sliding groove and a gear part located on the sliding groove. The first rebound housing is also provided with a linkage part connected to the sliding groove. The linkage part is provided with a sliding engagement part that meshes with one side of the gear part. The housing is provided with a guide engagement part that meshes with the other side of the gear part.

[0017] To improve the locking effect of the locking mechanism, the locking mechanism includes a trigger pushing part that can abut against the sliding member, a trigger member connected to the trigger pushing part, and a trigger elastic part for locking the first rebound housing. The trigger member includes a first trigger end that abuts against the trigger pushing part, a second trigger end that abuts against the trigger elastic part, and a trigger connecting part that connects to the first trigger end and the second trigger end.

[0018] To improve the triggering effect of the triggering elastic part, the triggering elastic part includes a second elastic part that abuts against the housing, a positioning part disposed on the first rebound housing, a protruding fixing block that locks with the positioning part, and a trigger mounting cavity through which the triggering connection part can pass. The trigger mounting cavity is provided with a second trigger end connecting groove and a step part that cooperates with the second trigger end.

[0019] To improve the positioning effect of the positioning part within the housing, the positioning part includes a positioning housing with one end hinged to the accommodating cavity and a positioning post disposed on the positioning housing. The first rebound housing is provided with a second guide groove, and the positioning post is located within the second guide groove. The housing is also provided with a guide rail for the positioning post to move. The guide rail is provided with a guide part, and the guide part is provided with a first guide end for guiding the positioning post to move in a first position direction and a second guide end for guiding the positioning post to move in a second direction.

[0020] In order to improve the contact effect between the elastic reset part and the first buffer assembly, the elastic reset part is provided with a first clearance end and a first engagement end, and the first buffer assembly is provided with a second clearance end that cooperates with the first clearance end and a second engagement end that cooperates with the first engagement end.

[0021] Furthermore, when the rebound mechanism moves to the second position and locks with the locking mechanism, the drawer is in the closed state; when the rebound mechanism returns to the first position from the second position, the drawer is in the open state.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. This invention uses a pushing mechanism to move relative to the housing to open or close the drawer. When the drawer is closed, the rebound mechanism moves from a first position to a second position, and a locking mechanism locks the rebound mechanism in the second position. When the locking mechanism is unlocked, the reset component moves the rebound mechanism from the second position back to the first position. During the process of the rebound mechanism resetting towards the first position, the rebound mechanism drives the pushing mechanism to move, causing the drawer to open. The first buffer component contacts the elastic buffer component and causes the elastic buffer component to retract. The kinetic energy on the pushing mechanism is converted into the elastic potential energy of the elastic buffer component when it retracts during the process of the first buffer component and the elastic buffer component colliding. Through energy conversion, the drawer forms a buffering effect when it moves from the second position to the first position. This invention, through the cooperation of the first buffer component and the elastic buffer component, makes the pushing mechanism move smoothly, avoiding the collision of items in the drawer during rapid movement of the drawer, thus preventing noise.

[0024] 2. During the process of the push mechanism moving from the first position to the second position, when the mating part and the first triggering part abut in the second position, the kinetic energy of the push mechanism is converted into the elastic potential energy of the reset housing as it retracts during the abutment between the first buffer component and the elastic buffer component. The retraction of the reset housing causes the hinged housing to rotate relative to the first rebound housing. The buffer component, through energy conversion, creates a buffering effect when the drawer moves from the first position to the second position, ensuring smooth movement of the push mechanism when the drawer changes from open to closed. During the process of the push mechanism moving from the second position to the first position, the kinetic energy of the push mechanism is converted into the elastic potential energy of the elastic reset part as it retracts during the abutment between the first buffer component and the buffer block on the reset housing. The buffer component, through energy conversion, creates a buffering effect when the drawer moves from the second position to the first position, ensuring smooth movement of the push mechanism when the drawer changes from closed to open.

[0042] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4The illustrated mechanism with a rebound function includes a housing 1, a buffer assembly 2, and a push mechanism 3 for connecting to a drawer and being movable relative to the housing 1 to drive the drawer to open or close. The housing 1 is provided with a rebound mechanism 4, a first trigger part 12, and a locking mechanism 5.

[0044] The rebound mechanism 4 is movable relative to the housing 1, and a reset component 6 is provided between the rebound mechanism 4 and the housing 1 to reset the rebound mechanism 4 to a first position; the rebound mechanism 4 can move to a second position when the drawer is closed;

[0045] The buffer assembly 2 includes at least one first buffer assembly 7 disposed on the pushing mechanism 3, and a retractable elastic buffer assembly 8 disposed on the rebound mechanism 4.

[0046] The rebound mechanism 4 includes a first rebound housing 41, the first rebound housing 41 is provided with a first receiving cavity 411, and the elastic buffer assembly 8 includes a hinged housing 81 with one end hinged in the first receiving cavity 411, an elastic reset part 83 connected to the hinged housing 81 and extending out of the outer side of the housing 1, and a first elastic block 82 with one end abutting against the hinged housing 81.

[0047] The locking mechanism 5 is used to lock the rebound mechanism 4 in the second position;

[0048] When the rebound mechanism 4 moves to the point where the first elastic block 82 contacts the first trigger part 12, the first trigger part 12 causes the first elastic block 82 to move relative to the hinge housing 81 and make way, so that the hinge housing 81 can rotate relative to the rebound mechanism 4 along the hinge point, so that the elastic reset part 83 retracts into the housing 1.

[0049] After the locking mechanism 5 is unlocked, the rebound mechanism 4 is reset to the first position under the action of the reset component 6, and drives the pushing mechanism 3 to move to open the drawer. During the process of the pushing mechanism 3 moving to open the drawer, the first buffer component 7 contacts the elastic reset part 83 and causes the elastic reset part 83 to retract.

[0050] This invention uses a pushing mechanism to move relative to the housing to open or close the drawer. When the drawer is closed, the rebound mechanism moves from a first position to a second position, and a locking mechanism locks the rebound mechanism in the second position. When the locking mechanism is unlocked, a reset component moves the rebound mechanism from the second position back to the first position. During the process of the rebound mechanism resetting towards the first position, the rebound mechanism drives the pushing mechanism to move, causing the drawer to open. The first buffer component contacts the elastic buffer component and causes the elastic buffer component to retract. The kinetic energy on the pushing mechanism is converted into the elastic potential energy of the elastic buffer component when it retracts as the first buffer component and the elastic buffer component come into contact. Through this energy conversion, a buffering effect is created when the drawer moves from the second position to the first position. This invention, through the cooperation of the first buffer component and the elastic buffer component, allows the pushing mechanism to move smoothly, preventing items in the drawer from colliding and making noise during rapid drawer movement.

[0051] During the movement of the push mechanism from the first position to the second position, when the mating part and the first triggering part abut in the second position, the kinetic energy of the push mechanism is converted into elastic potential energy when the reset housing retracts during the abutment between the first buffer component and the elastic buffer component. The retraction of the reset housing causes the hinged housing to rotate relative to the first rebound housing. The buffer component, through energy conversion, creates a buffering effect when the drawer moves from the first position to the second position, ensuring smooth movement of the push mechanism when the drawer changes from open to closed. During the movement of the push mechanism from the second position to the first position, the kinetic energy of the push mechanism is converted into elastic potential energy when the elastic reset part retracts during the abutment between the first buffer component and the buffer block on the reset housing. The buffer component, through energy conversion, creates a buffering effect when the drawer moves from the second position to the first position, ensuring smooth movement of the push mechanism when the drawer changes from closed to open.

[0052] Furthermore, in order to improve the buffering effect, the kinetic energy on the driving mechanism is converted into more of the elastic potential energy when the first buffer component retracts during the process of the first buffer component and the elastic buffer component resisting each other. The first buffer component is provided with multiple components.

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9 The diagram shows a mechanism with a rebound function. The first accommodating cavity 411 is provided with a relief opening 4111 for the elastic reset part 83 to retract. When the first rebound housing 41 is in the first position, the hinged housing 81 abuts against the side of the first elastic block 82.

[0054] With this design, because the hinged housing abuts against the side of the first elastic block, the hinged housing, which is hinged at one end within the accommodating cavity, cannot move. When the first buffer assembly abuts against the elastic buffer assembly, because the hinged housing cannot retract inward toward the clearance opening, the second engaging end on the first buffer assembly abuts against the first engaging end on the elastic buffer assembly. This causes the first buffer assembly of the pushing mechanism to move the elastic buffer assembly on the first rebound housing toward the second position. Specifically, during the process of the first rebound housing moving to the second position, the hinged housing remains abutted against the side of the first elastic block near its end, and the first elastic block can restrict the hinged housing from retracting inward toward the clearance opening.

[0055] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 , Figure 11 , Figure 14 and Figure 15 The illustrated mechanism has a rebound function. The first elastic block 82 includes a mating part 821, a connecting post 822 connected to the mating part 821, and a first elastic part 823 with one end abutting against the connecting post 822 and the other end abutting against the first rebound housing 41. When the mating part 821 abuts against the first trigger part 12 in the second position, the hinge housing 81 can rotate relative to the first rebound housing 41. The first rebound housing 41 is provided with a first guide groove 412, and the hinge housing 81 is provided with a protrusion 811 facing outward of the first guide groove 412.

[0056] In the first position, the hinged housing is always abutted against the side of the first elastic block, which restricts the hinged housing from retracting into the clearance opening. When the first rebound housing moves to the second position, the mating part on the first elastic block abuts against the first trigger part, driving the connecting post to move towards the first position. At this time, the hinged housing abuts against the end of the first elastic block and, guided by the first guide groove, allows the protrusion of the hinged housing to move within the first guide groove, enabling the hinged housing to reciprocate along the first guide groove towards the inside and outside of the clearance opening. When the locking mechanism is unlocked, as the first rebound housing moves towards the first position, the mating part on the first elastic block disengages from the first trigger part. At this time, the hinged housing abuts against the side of the first elastic block, and the hinged housing cannot retract into the clearance opening.

[0057] The first rebound housing 41 has a first opening 4110 communicating with the first accommodating cavity 411. The connecting post 822 extends from the first accommodating cavity 411 to the outside of the first opening 4110, and the first elastic part 823 is sleeved on the outside of the connecting post 822. When the rebound mechanism moves to the second position, the first elastic block abuts against the first trigger part located between the first position and the second position. At this time, the connecting post extends from the first accommodating cavity to the outside of the first opening. Since the first elastic part is sleeved on the outside of the connecting post, one end of the first elastic part abuts against the connecting post, and the other end of the first elastic part abuts against the first rebound housing. The connecting post moves towards the first position and compresses the first elastic part. When the rebound mechanism moves from the second position to the first position, the connecting block disengages from the first trigger part, the first elastic part resets, and pushes the connecting post from the first position to the second position. At this time, the connecting post moves from the outside of the first opening into the first accommodating cavity. The connecting post drives the mating part to contact the hinge housing, and the first elastic block resets.

[0058] The mating part 821 is provided with an unlocking part 8212 disposed in the direction of the first triggering part 12. The first rebound housing 41 is provided with a first rebound housing guide groove 415 for accommodating the unlocking part 8212. The first rebound housing guide groove 415 is provided with a first rebound housing guide groove opening 4151. One end of the unlocking part 8212 is disposed outside the first rebound housing guide groove opening 4151. With this design, when the rebound mechanism moves to the second position, since one end of the unlocking part is located outside the opening of the first rebound housing groove, when the unlocking part abuts against the first triggering part, the unlocking part moves towards the inside of the opening of the first rebound housing guide groove. At the same time, the unlocking part drives the mating part to move from the second position to the first position. The thrust of the first triggering part on the unlocking part is greater than the elastic force of the first elastic part on the mating part. The connecting column moves towards the first position and compresses the first elastic part, causing the connecting column to disengage from the hinge housing. When the rebound mechanism moves from the second position to the first position, the unlocking part on the mating part disengages from the first triggering part. At this time, the elastic force of the first elastic part on the connecting column is greater than the thrust of the connecting column on the first elastic part. The first elastic part resets and pushes the mating part to move from the first position to the second position. The mating part contacts the hinge housing, and the hinge housing abuts against the side of the mating part. The unlocking part moves from the inside of the opening of the first rebound housing guide groove to the outside of the opening of the first rebound housing guide groove, and the mating part resets.

[0059] like Figure 14The device shown has a rebound structure. The hinge housing 81 is provided with a hinge housing mounting cavity 814 and a hinge housing opening 812 communicating with the hinge housing mounting cavity 814. The elastic reset part 83 includes a reset housing 831 disposed on the hinge housing mounting cavity 814 and passing through the hinge housing opening 812, and a reset housing elastic member 832 connected at one end to the reset housing 831. The other end of the reset housing elastic member 832 abuts against the hinge housing mounting cavity 814. The reset housing 831 is provided with a buffer block 8311 that contacts the first buffer assembly 7.

[0060] When the first rebound housing returns to the first position from the second position, the hinged housing cannot move because it abuts against the side of the first elastic block. When the first buffer assembly abuts against the elastic buffer assembly, the hinged housing cannot retract to the inside of the clearance opening. At this time, the second clearance end on the first buffer assembly abuts against the first clearance end on the buffer block. The first buffer assembly drives the reset housing to move to the inside of the clearance opening. One end of the reset housing continues to move to the inside of the clearance opening through the hinged housing mounting cavity and the hinged housing opening. The reset housing continues to move to the first position by retracting and clearing. When the first buffer assembly disengages from the elastic buffer assembly, the force applied to the reset housing disappears. The elastic force of the reset housing elastic element is greater than the thrust of the reset housing. The reset housing elastic element pushes the reset housing to move in the opposite direction of the push. One end of the reset housing enters the hinged housing mounting cavity from the hinged housing opening. The reset housing moves to the outside of the clearance opening and is located outside the clearance opening, which also drives the buffer block to reset at the same time.

[0061] Furthermore, the buffer block is made of an elastic material, which can reduce wear and increase the lifespan of the first buffer assembly and the buffer block when the first buffer assembly comes into contact with the buffer block.

[0062] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6The illustrated mechanism has a rebound function. The pushing mechanism 3 is provided with a pushing block 31. The rebound mechanism 4 is provided with a sliding member 43 that abuts against the pushing block 31 and a second rebound housing 42 that is connected to the sliding member 43 on one side and connected to the first rebound housing 41. The reset assembly 6 includes an adjustment device 61 fixedly disposed at one end of the housing 1 and a reset elastic member 62 disposed on the second rebound housing 42 and connected to the adjustment device 61. With this design, since the adjusting device is fixed at one end of the housing, when the first rebound housing moves from the first position to the second position, the first rebound housing drives the second rebound housing to move. Since the reset elastic element is set on the second rebound housing and its other end is on the adjusting device, the second rebound housing pulls the reset elastic element to deform during the movement. When the locking mechanism is unlocked, the elastic force of the reset elastic element is greater than the pulling force applied by the second rebound housing. The reset elastic element drives the second rebound housing to move towards the first position, and the second rebound housing simultaneously drives the first rebound housing to move towards the first position. At the same time, the second rebound housing pushes the sliding element to move, and the sliding element abuts against the pushing mechanism and drives the pushing mechanism to move towards the first position simultaneously.

[0063] Furthermore, the adjusting device 61 is provided with a threaded portion 611, and a first engaging portion 612 and a second engaging portion 613 respectively connected to the threaded portion 611. The first engaging portion 612 is connected to one of the reset elastic members 62, and the second engaging portion 613 is connected to the other reset elastic member 62. The threaded portion 611 has a first thread 6111 and a second thread 6112 with two different rotation directions. The first thread 6111 engages with the first engaging portion 612, and the second thread 6112 engages with the second engaging portion 613. One reset elastic member 62 is connected to the end of the first engaging portion 612 near the adjusting device 61, and the other reset elastic member 62 is connected to the other end of the second engaging portion 613 near the adjusting device 61. When the adjustment pop-out force is increased, the first engaging portion 612 rotates to one side, causing the end of one reset elastic member 62 to move away from the second position, and the second engaging portion 613 rotates to the other side, causing the end of the other reset elastic member 62 to move away from the second position. By further tightening the reset elastic members 62, the pop-out force is increased.

[0064] Furthermore, such as Figure 16 and Figure 17As shown, the pushing mechanism 3 is provided with an adjusting part 32. The pushing mechanism 3 also includes a first housing 33 and a second housing 34. The pushing block 31 and the first buffer assembly 7 are respectively disposed on the first housing 33. The second housing 34 is provided with a boss 341 to restrict the forward and backward movement of the adjusting part 32. The first housing 33 is provided with a first housing mating part 331. The adjusting part 32 is threadedly connected to the first housing mating part 331. Through the adjustment part and the first housing mating part 331, the first housing of the pushing mechanism moves relative to the second housing of the pushing mechanism, causing the distance between the pushing block 31 and the sliding member to change. The first housing 33 is provided with a first housing buckle 332. The second housing 34 of the pushing mechanism is provided with a groove 342 that cooperates with the buckle 332 of the first housing of the pushing mechanism. The groove of the second housing of the pushing mechanism has a certain space, so that the buckle of the first housing of the pushing mechanism can move in the groove of the second housing of the pushing mechanism. The distance between the first housing and the second housing of the pushing mechanism can be changed by the adjustment part, so that the distance between the first housing of the pushing mechanism and the sliding member can be increased or decreased. When the distance between the pushing mechanism and the sliding member increases, the pushing mechanism needs to move a certain distance before the rebound mechanism can unlock and reset. When the distance between the pushing mechanism and the sliding member decreases, the pushing mechanism moves a short distance and the rebound mechanism unlocks and resets immediately. At this time, the unlocking and rebound are more sensitive.

[0065] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 12 and Figure 13The illustrated mechanism has a rebound function. The second rebound housing 42 is provided with a sliding groove 421 and a gear part 422 located on the sliding groove 421. The first rebound housing 41 is also provided with a linkage part 413 connected to the sliding groove 421. The linkage part 413 is provided with a sliding engagement part 4131 that meshes with one side of the gear part 422. The housing 1 is provided with a guide engagement part 13 that meshes with the other side of the gear part 422. With this design, since the sliding engagement part on the first rebound housing meshes with one side of the gear part, and the guide engagement part on the housing meshes with the other side of the gear part, when the first rebound housing moves from the first position to the second position, the first rebound housing drives the second rebound housing to move simultaneously towards the second position. When the second rebound housing returns to its original position, the second rebound housing drives the first rebound housing to move simultaneously from the second position to the first position. By utilizing the gear part of the second rebound housing to mesh with the sliding engagement part and the guide engagement part on the first rebound housing respectively, the synchronization of the rebound of the first and second rebound housings is improved when the drawer is opened or closed, and the effect of transmitting large power and high efficiency is achieved.

[0066] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The shown is a mechanism with a rebound function. The locking mechanism 5 includes a trigger push part 51 that can abut against the sliding member 43, a trigger member 52 connected to the trigger push part 51, and a trigger elastic part 53 for locking the first rebound housing 41. The trigger member 52 includes a first trigger end 521 that abuts against the trigger push part 51, a second trigger end 522 that abuts against the trigger elastic part 53, and a trigger connecting part 523 that connects to the first trigger end 521 and the second trigger end 522. With this design, when the slider moves to the second position and abuts against the trigger push part, the trigger push part moves to the second position simultaneously. The trigger push part drives the first trigger end to rotate and simultaneously drives the second trigger end to rotate. After the second trigger end rotates in the connecting groove and abuts against the trigger elastic part, it drives the trigger elastic part to move to the second position. At this time, the locking mechanism unlocks. When the force applied to the slider disappears, the rebound mechanism, because the elastic force is greater than the pulling force, drives the rebound mechanism to move in the opposite direction of the pushing direction. At this time, the rebound mechanism resets, the slider disengages from the trigger push part, the second trigger end continues to rotate, and at the same time, the second trigger end drives the trigger connecting part to rotate, and the first trigger end resets.

[0067] Furthermore, in order to enable the first trigger end to successfully reset after rotation, the side of the trigger push part that abuts against the first trigger end is set in a stepped shape.

[0068] Furthermore, a balance bar 9 is provided between the two rebound and buffer mechanisms. The trigger connection 523 has a locking part 10 located at the end of the trigger connection 523. The locking part 10 includes a buckle 101 and a bushing 102. The bushing 102 includes a first engaging groove 1021 that matches the shape of the balance bar 9, and a second engaging groove 1022 that matches the buckle 101. When the trigger connection 523 rotates, the buckle 101 engages in the second engaging groove 1022 to achieve linkage. The balance bar enables the two rebound mechanisms to achieve balance and synchronization. The balance bar and the mechanism are connected by a locking mechanism. The connection of the parts further reduces the difficulty of installation, improves installation efficiency, and makes disassembly and installation convenient. Since the buckle engages in the second engagement groove, when one set of mechanisms drives the drawer to open or close, the buckle engages with the second engagement groove, which in turn drives one end of the balance bar to rotate. The other end of the balance bar drives the second engagement groove of another set of mechanisms to engage with the buckle. By triggering the connecting part, the other mechanism is driven, realizing the synchronization of the two sets of mechanisms and ensuring smooth drawer movement. When pushing or pulling the drawer, even if the force deviates from the center of the drawer, the opening and closing of the drawer can still be kept synchronized.

[0069] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The mechanism shown has a rebound function. The trigger elastic part 53 includes a second elastic part 531 that abuts against the housing 1, a positioning part 532 disposed on the first rebound housing 41, a protruding fixing block 533 that locks with the positioning part 532, and a trigger mounting cavity 534 through which the trigger connecting part 523 can pass. The trigger mounting cavity 534 is provided with a second trigger end connecting groove 5341 and a step part 5342 that cooperates with the second trigger end 522. With this design, when the first rebound housing moves to the second position, the positioning part on the first rebound housing abuts against the protruding fixing block to form a locked state. When the slider moves to the second position and abuts against the trigger pushing part, the trigger pushing part moves to the second position simultaneously. The trigger pushing part drives the first trigger end to rotate and simultaneously drives the second trigger end to rotate. After the second trigger end rotates in the second trigger end connecting groove and abuts against the step part, it drives the trigger elastic part to move towards the housing and squeeze the second elastic part. At this time, the positioning part disengages from the protruding fixing block, and the locking mechanism unlocks. When the force applied to the slider disappears, the rebound mechanism, due to the elastic force being greater than the pulling force, drives the rebound mechanism to move in the opposite direction of the pushing direction. At this time, the rebound mechanism resets, the slider disengages from the trigger pushing part, and the second trigger end continues to rotate. At the same time, the second trigger end drives the trigger connecting part to rotate and reset into the second trigger end connecting groove, and the first trigger end resets.

[0070] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 10The illustrated mechanism has a rebound function. The positioning part 532 includes a positioning housing 5321 with one end hinged to the accommodating cavity 411 and a positioning post 5322 disposed on the positioning housing 5321. The first rebound housing 41 is provided with a second guide groove 414, and the positioning post 5322 is located in the second guide groove 414. The housing 1 is also provided with a guide rail 11 for the positioning post 5322 to move. The guide rail 11 is provided with a guide part 111. The guide part 111 is provided with a first guide end 1111 for guiding the positioning post 5322 to move in a first position direction and a second guide end 1112 for guiding the positioning post 5322 to move in a second direction. This design moves the first rebound housing towards the second position. The positioning pin first passes through the guide rail. Due to the second guide groove, the positioning pin can move along the guide rail towards the second position. The first guide end abuts against the protruding fixing block, which prevents the positioning pin from moving further within the guide rail. When the locking mechanism unlocks, the first rebound housing moves towards the first position, disengaging the positioning pin from the protruding fixing block. After abutting against the second guide end, the positioning pin, due to the second guide groove, enters the guide rail along the guide portion and moves towards the first position. The cooperation between the protruding fixing block and the guide portion locks the first rebound housing mechanism in the second position. Unlocking is achieved by the contact between the trigger push part and the trigger element. Pushing the push mechanism towards the second position when closing the drawer and pressing the push mechanism towards the second position when opening the drawer allows for quick locking and unlocking, reducing the steps of opening and closing the drawer and improving the user experience.

[0071] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The device shown has a rebound structure. The elastic reset part 83 is provided with a first clearance end 801 and a first engagement end 802. The first buffer assembly 7 is provided with a second clearance end 71 that cooperates with the first clearance end 801 and a second engagement end 72 that cooperates with the first engagement end 802.

[0072] Specifically, the elastic buffer assembly has a first clearance end and a first engagement end located in the direction of the elastic buffer assembly toward the push mechanism, and a second clearance end and a second engagement end on the first buffer assembly located in the direction of the first buffer assembly toward the elastic buffer assembly. The first clearance end 801 has a beveled design, with the bevel of the first clearance end 801 facing the direction of the drawer closed. The second clearance end 71 has a beveled design and matches the bevel shape of the first clearance end 801, with the bevel of the second clearance end 71 facing the direction of the drawer open.

[0073] The first engaging end 802 and the second engaging end 72 have a straight structure. When the drawer is closed, the second engaging end 72 contacts the first engaging end 802, pushing the mechanism 3 to move towards the second position and causing the first rebound housing 41 to move to the second position, so that the rebound mechanism 4 and the locking mechanism 5 are locked.

[0074] Furthermore, when the pushing mechanism moves from the first position to the second position, the second engaging end on the first buffer assembly abuts against the first engaging end on the elastic buffer assembly, and the thrust of the pushing mechanism drives the elastic buffer assembly to move the rebound mechanism to the second position.

[0075] Furthermore, when the rebound mechanism resets and the pushing mechanism moves from the second position to the first position, the second clearance end on the first buffer component abuts against the first clearance end on the elastic buffer component. The thrust of the pushing mechanism drives the elastic buffer component to retract, and the first buffer component is driven by the reaction force to reduce the moving speed of the pushing mechanism to achieve buffering. While the elastic buffer component retracts and resets, the pushing mechanism continues to move towards the second position.

[0076] like Figures 1 to 17 As shown, the implementation method of this embodiment is as follows:

[0077] The first buffer assembly 7 has two components.

[0078] When the drawer is in the open to closed state, the first rebound housing 41 moves from the first position to the second position. Since the hinge housing 81 abuts against the side of the first elastic block 82, the hinge housing 81, which is hinged at one end in the accommodating cavity 411, cannot move. When the first buffer assembly 7 abuts against the elastic buffer assembly 8, since the hinge housing 81 cannot retract into the clearance opening 4111, the second engaging end 72 on the first buffer assembly 7 abuts against the first engaging end 802 provided on the elastic buffer assembly 8. The first buffer assembly 7 of the pushing mechanism 3 drives the elastic buffer assembly 8 on the first rebound housing 41 to move towards the second position.

[0079] Since the sliding engagement part 4131 on the first rebound housing 41 meshes with one side of the gear part 422 on the second rebound housing 42, and the guide engagement part 13 on the housing 1 meshes with the other side of the gear part 422, when the first rebound housing 41 moves from the first position to the second position, the first rebound housing 41 drives the second rebound housing 42 to move simultaneously towards the second position. Since the reset elastic element 62 is provided on the second rebound housing 42 and the other end is on the adjustment device 61, the second rebound housing 42 pulls the reset elastic element 62 to deform during the movement. The positioning post 5322 first passes through the guide rail 11. Due to the provision of the second guide groove 414, the positioning post 5322 can move along the direction of the guide rail 11 towards the second position. The first guide end 1111 abuts against the protruding fixing block 533. The protruding fixing block 533 and the guide part 111 cooperate to prevent the positioning post 5322 from continuing to move in the guide rail 11.

[0080] When the first rebound housing 41 moves to the second position, the mating part 821 on the first elastic block 82 abuts against the first trigger part 12, driving the connecting post 822 to move towards the first position. At this time, the hinge housing 81 disengages from the side of the first elastic block 82 and can be guided by the first guide groove 412, allowing the protrusion 811 of the hinge housing 81 to move in the first guide groove 412, so that the hinge housing 81 can move along the first guide groove 412 towards the inner side of the clearance opening 4111. At this time, the first buffer group... When the second engaging end 72 on component 7 abuts against the first engaging end 802 of the elastic buffer assembly 8, it drives the hinge housing 81 to move the elastic reset part 83 to the inside of the clearance opening 4111. When the first buffer assembly 7 disengages from the elastic buffer assembly 8, the hinge housing 81 drives the elastic reset part 83 to move to the outside of the clearance opening 4111 to reset. During the process of the pushing mechanism 3 moving from the first position to the second position, the buffer assembly 2 produces a buffering effect, making the pushing mechanism 3 move smoothly. At this time, the drawer is in the closed state.

[0081] When the drawer changes from the closed state to the open state, the push mechanism 3 is pushed, the push block 31 abuts against the slider 43 and pushes the slider 43 to move towards the second position. When the slider 43 moves towards the second position and abuts against the trigger push part 51, the trigger push part 51 moves towards the second position at the same time. The trigger push part 51 drives the first trigger end 521 to rotate, and at the same time drives the second trigger end 522 to rotate. After the second trigger end 522 rotates in the second trigger end connecting groove 5341 and abuts against the step part 5342, it drives the trigger elastic part 53 to move towards the housing 1. The second elastic part 531 is pressed and squeezed. At this time, the positioning part 532 is disengaged from the protruding fixing block 533, and the locking mechanism 5 is unlocked. When the force applied to the sliding member 43 disappears, the elastic force of the reset elastic member 62 is greater than the pulling force applied by the second rebound housing 42. The reset elastic member 62 drives the second rebound housing 42 to move towards the first position. At the same time, the second rebound housing 42 drives the first rebound housing 41 to move towards the first position. Meanwhile, the second rebound housing 42 pushes the sliding member 43 to move. The sliding member 43 abuts against the pushing mechanism 3 and drives the pushing mechanism 3 to move towards the first position.

[0082] At this time, the slider 43 disengages from the trigger push part 51, the second trigger end 522 continues to rotate, and at the same time, the second trigger end 522 drives the trigger connection part 523 to rotate and reset into the second trigger end connection groove 5341, and the first trigger end 521 resets at the same time.

[0083] When the locking mechanism is unlocked, the first rebound housing 41 moves toward the first position, the positioning post 5322 disengages from the protruding fixing block 533, and after the positioning post 5322 abuts against the second guide end 414, due to the setting of the second guide groove 414, the positioning post 5322 enters the guide rail 11 along the guide part 111 and moves toward the first position.

[0084] When the first rebound housing 41 returns to the first position from the second position, the hinged housing 81 abuts against the side of the first elastic block 82, preventing the hinged housing 81, which is hinged at one end in the accommodating cavity 411, from moving. When the first buffer assembly 7 abuts against the elastic buffer assembly 8, the hinged housing 81 cannot retract into the clearance opening 4111. At this time, the second clearance end 71 on the first buffer assembly 7 abuts against the first clearance end 801 on the buffer block 8311. The first buffer assembly 7 drives the reset housing 831 to move into the clearance opening 4111. One end of the reset housing 831 continues to move into the clearance opening 4111 through the hinged housing mounting cavity 814 and the opening of the hinged housing 81. The reset housing 831 retracts and clears, thus pushing the mechanism. 3. Continue moving towards the first position. When the first buffer component 7 disengages from the elastic buffer component 8, the force applied to the reset housing 831 disappears. The elastic force of the reset housing elastic element 832 is greater than the thrust of the reset housing 831. The reset housing elastic element 832 pushes the reset housing 831 to move in the opposite direction of the push. One end of the reset housing 831 enters the hinge housing mounting cavity 814 from the opening of the hinge housing 81. The reset housing 831 moves to the outside of the clearance opening 4111 and is located outside the clearance opening 4111. The buffer block 8311 is also reset at the same time. During the process of the pushing mechanism 3 moving from the second position to the first position, the buffer component 2 produces a buffering effect, making the pushing mechanism 3 move smoothly. At this time, the drawer is in the open state.
