Description
Technical Field
[0001] The invention relates to the technical field of furniture guide rail mechanisms, in particular to a self-closing buffer rebound box suitable for guide rails. Background Art
[0002] In the field of furniture drawers, rebound drawers often use drawer rebounders to achieve touch-press drawer opening and closing. Specifically, in the prior art such as Chinese patent CN213282174 U, a guide rail rebounder, CN2022109394963, a push-rebound guide rail rebound box, and CN217039387U, a new push-rebound self-locking device for a hidden slide rail, the functions of which are relatively simple. For example, they only have one or two of the rebound function, buffer function, and self-closing function, and cannot have all three functions. The main reason is that the more complex the functional structure, the larger the volume of the rebound self-closing box, especially the inability to adapt to the existing self-closing box fixedly installed on the inner side of the drawer slide rail, and the hidden function cannot be achieved. Secondly, the more complex the functional structure of the existing rebound self-closing box product, the worse its structural stability, especially in the actual use process, it is easy to have abnormal problems such as stuck and collision, resulting in too many customer complaints and other quality problems. Summary of the invention
[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a stable, reliable and functional self-closing buffer rebound box suitable for guide rails.
[0004] In order to achieve the above-mentioned purpose, the present invention provides a self-closing buffer rebound box suitable for a guide rail, comprising a box body, a self-closing bumper and a rebound slide seat which are directional and slideable on the box body in a forward and backward direction, wherein the self-closing bumper can be locked or unlocked relative to the box body during sliding; a self-closing elastic member is provided between the self-closing bumper and the rebound slide seat, and a rebound elastic member is provided between the rebound slide seat and the box body; the self-closing bumper and the rebound slide seat can be in relative contact with each other; and also includes a rebound component which directional and slides synchronously with the rebound slide seat, and the rebound component includes a rebound pull rod hinged to the rebound slide seat, and a rebound pull rod directly or indirectly elastically hinged to the rebound pull rod.

[0006] Furthermore, the rebound pull rod is formed with a sliding shaft portion which is slidably embedded in the guide channel.
[0007] Furthermore, the rebound rocker arm is indirectly hinged on the rebound slide seat, wherein the rebound rocker arm is hinged with the rebound pull rod, and the sliding shaft portion is correspondingly arranged at the hinge position of the rebound pull rod and the rebound rocker arm.
[0008] Furthermore, the guide channel forms a limiting groove at the junction of the introduction section and the outlet section for blocking the sliding shaft portion from moving forward, wherein the sliding shaft portion can slide into the limiting groove from the introduction section to block the sliding shaft portion from moving forward directly, so that the sliding shaft portion can only move backward, exit the limiting groove and enter the outlet section before moving forward.
[0009] Furthermore, it also includes an energy storage slide seat which is arranged on the box body and slides forward and backward in a directional manner. The energy storage slide seat is formed with an upper block and a lower block which extend to the introduction section and the outlet section respectively, wherein the lower block and the fixed block abut against each other at the junction of the introduction section outlet and the outlet section entrance to form a limiting groove which blocks the sliding shaft part from moving forward, and the sliding shaft part can push the upper block to move backward to avoid space during the sliding of the introduction section so that the sliding shaft part can slide into the limiting groove; the sliding shaft part can only move backward to exit the limiting groove and enter the outlet section, and the sliding shaft part can push open the lower block during the sliding of the outlet section.
[0010] Furthermore, it also includes a synchronous rod which is pivotally connected to the box body and is in transmission cooperation with the energy storage slide seat.
[0011] Furthermore, the box body is also provided with a rebound avoidance channel which is connected to the outlet of the introduction section and the limit groove and extends backward. As the sliding shaft portion continues to move backward, the sliding shaft portion slides from the introduction section into the rebound avoidance channel. At the same time, the rebound rocker arm switches from the outward swing state to the inward swing state.
[0012] Furthermore, the rebound slide seat is formed with an elastic part which contacts the rebound swing arm, and the rebound swing arm has an outward swinging tendency due to the elastic force generated by the elastic part.

[0017] Furthermore, a stop elastic member is provided between the stop bumper and the box body.
[0018] Furthermore, it also includes an energy storage check piece pivotally connected to the rebound slide, and the box body is formed with a check slide for sliding cooperation with the energy storage check piece, wherein the check slide is composed of a cyclically connected energy storage section and a pop-up section; when the rebound slide moves backward relative to the box body, the energy storage check piece moves accordingly along the energy storage section; conversely, when the rebound slide moves forward relative to the box body, the energy storage check piece moves accordingly along the pop-up section; at least one check position is formed in the area of the energy storage section for stopping and limiting the forward movement of the energy storage check piece.

DETAILED DESCRIPTION
[0028] In order to facilitate the understanding of the present invention, the present invention is described more fully below with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.
[0029] See attached Figure 1-13As shown, in the present embodiment, a self-closing buffer rebound box suitable for a guide rail, for the sake of convenience of explanation, the drawer opening direction is defined as forward movement, and the drawer closing direction is defined as backward movement, and is specifically applied to the lower rail in the drawer slide rail, by providing a fixed collision block 100 and a rebound collision member 200 (the fixed collision block 100 is located in front of the rebound collision member 200) on the upper rail of the drawer slide rail (not shown), the self-closing buffer rebound specifically includes a box body 1, a self-closing collision member 2 and a rebound slide 3 that are directional and slideable on the box body 1 in a forward and backward manner, and a rebound component 4 that directional and slides synchronously with the rebound slide 3, wherein the self-closing collision member 2 can be locked and limited or unlocked relative to the box body 1 during sliding, specifically, the self-closing collision member 2 of the present embodiment is composed of a self-closing slide 21 that is slidable on the box body 1 in a forward and backward manner, and a moving collision block 22 that is pivotally connected to the front end of the self-closing slide 21. , and the movable collision block 22 is formed with an arc-shaped gear position for contact and cooperation with the fixed collision block 100 preset on the drawer slide; secondly, a clearance groove is formed at the front position of the box body 1 for the movable collision block 22 of the self-closing collision member 2 to swing in or out, that is: when the drawer slide is pulled outward, the fixed collision block 100 is embedded in the arc-shaped gear position and synchronously drives the movable collision block 22 and the self-closing slide 21 to move forward relative to the box body 1 until the movable collision block 22 is swung into the clearance groove, and the fixed collision block 100 can be disengaged from the arc-shaped gear position, and the self-closing slide 21 remains stationary because the movable collision block 22 is restricted in the clearance groove; on the contrary, when the drawer slide is pushed inward, the fixed collision block 100 collides with the movable collision block 22 and gradually embeds into the arc-shaped gear position, then the movable collision block 22 is pressed and swings out of the clearance groove, and then the fixed collision block 100, the movable collision block 22 and the self-closing slide 21 move backward synchronously.
[0030] For ease of explanation, the following definitions are Figure 1-13 The embodiment shown is embodiment 1, Figure 14-16 Another embodiment shown is embodiment 2.
[0031] In the first and second embodiments, a self-closing elastic member 5 is provided between the self-closing bumper 2 and the rebound slide 3, that is, the two ends of the self-closing elastic member 5 are respectively connected to the tail of the self-closing bumper 2 and the rebound slide 3, wherein, when the self-closing bumper 2 and the rebound slide 3 are relatively far apart, the self-closing elastic member 5 is stretched to store energy, and the self-closing bumper 2 and / or the rebound slide 3 need to overcome the stretching elastic force generated by the self-closing elastic member 5 to move away, thereby achieving the effect of energy storage; conversely, when the self-closing bumper 2 and the rebound slide 3 are relatively close to each other, the self-closing elastic member 5 releases energy and resets, and the self-closing bumper 2 and / or the rebound slide 3 are relatively close to each other under the elastic force generated by the self-closing elastic member 5.
[0032] Furthermore, the self-closing elastic member 5 is a tension spring.
[0033] In this embodiment, a buffer unit 8 fixed on the box body 1 or the rebound slide 3 is further included. Specifically, referring to the embodiment 1 shown in the drawings, the buffer unit 8 is fixed on the box body 1 and the telescopic end of the buffer unit 8 is connected to the self-closing bumper 2, while referring to the embodiment 2 shown in the drawings, the buffer unit 8 is fixed on the rebound slide 3 and the telescopic end of the buffer unit 8 is connected to the self-closing bumper 2. The buffer unit 8 here will move synchronously and directional with the rebound slide 3. The buffer unit 8 in the above two embodiments is a telescopic damping rod, and the damping effect of the telescopic damping rod is used to buffer the self-closing bumper 2 during the backward movement, so that the self-closing bumper 2 can avoid excessive impact, collision and noise with the box body 1 and the rebound slide 3 when moving backward.
[0034] In the present embodiment, a rebound elastic member 32 is provided between the rebound slide 3 and the box body 1. Referring to the embodiment 1 shown in the accompanying drawings, the rebound elastic member 32 adopts a tension spring, and the two ends of the rebound elastic member 32 are respectively connected to the box body 1 and the rebound slide 3, and the elastic force generated by the rebound elastic member 32 forces the rebound slide 3 to move forward; specifically, when the rebound slide 3 moves backward relative to the box body 1, the rebound elastic member 32 is stretched to store energy, and the rebound slide 3 needs to overcome the stretching elastic force generated by the rebound elastic member 32 to move backward; conversely, when the rebound slide 3 moves forward relative to the box body 1, the rebound elastic member 32 contracts to release energy, and the rebound slide 3 moves forward relative to the box body 1 under the elastic action of the rebound elastic member 32. In the second embodiment shown in the accompanying drawings, the rebound elastic member 32 adopts a compression spring, one end of the rebound elastic member 32 is fixedly connected to the rear end of the rebound slide 3 and the other end of the rebound elastic member 32 elastically contacts the box body 1. Specifically, when the rebound slide 3 moves backward relative to the box body 1, the rebound elastic member 32 is compressed and stores energy, and the rebound slide 3 needs to overcome the compression reaction elastic force generated by the rebound elastic member 32 to move backward; conversely, when the rebound slide 3 moves forward relative to the box body 1, the rebound elastic member 32 stretches and resets to release energy, and the rebound slide 3 moves forward relative to the box body 1 under the elastic action of the rebound elastic member 32.
[0035] In this embodiment, see the attached Fig.17As shown, in order to improve the situation where the drawer and the self-closing buffer rebound box retreat and open due to insufficient user thrust during actual use, it also includes an energy storage check member 10 pivotally connected to the rebound slide 3, and the box body 1 is formed with a check slide 13 for sliding cooperation with the energy storage check member 10 (that is, the energy storage check member 10 is formed with a check shaft portion for slidingly embedding into the check slide 13), wherein the check slide 13 is composed of a cyclically connected energy storage section 131 and a pop-up section 132, when the rebound slide 3 moves backward relative to the box body 1, the energy storage check member 10 moves accordingly along the energy storage section 131; conversely, when the rebound slide 3 moves forward relative to the box body 1, the energy storage check member 10 moves accordingly along the pop-up section 132. In addition, at least one check position 133 is formed in the area of the energy storage section 131 for stopping and limiting the forward movement of the energy storage check member 10. The energy storage check member 10 will jump over the check position 133 during the normal backward movement along the energy storage section 131, and will not interfere with its normal backward movement. However, once the thrust is insufficient, the rebound slide 3 will move forward in the opposite direction along the energy storage section 131 under the elastic force of the rebound elastic member 32, and will be stuck in the adjacent check position 133, thereby limiting the range of retreat and achieving the effect of energy storage. At the same time, when the user closes the drawer again, there is no need to increase extra force to close the drawer normally.
[0036] In this embodiment, see the attached Fig.17 As shown, the energy storage section 131 includes at least one group of slide units. Those skilled in the art can set a corresponding number of slide units according to the actual required energy storage level. For the convenience of explanation, this embodiment takes two groups of slide units as an example for explanation. The two groups of slide units are connected in sequence to form the energy storage section 131. Specifically, each group of slide units includes a horizontal slide 1311, an uphill slide 1312 and a downhill slide 1313 that are connected in sequence, and each check position 133 is arranged one by one adjacent to the upper position of each uphill slide 1312 to stop and limit the energy storage stop position in the uphill slide 1312. The return piece moves forward, that is, when the user pushes the drawer to drive the rebound slide 3 and the energy storage check piece to move backward, the energy storage check piece in a normal state will slide along the horizontal slide 1311, the uphill slide 1312 and the downhill slide 1313 in sequence, and will jump over the adjacent check position 133 while moving along the uphill slide 1312. Once the thrust is insufficient, the rebound slide 3 will drive the energy storage check piece to move forward in the opposite direction along the energy storage section 131 under the elastic force of the rebound elastic piece, thereby moving forward in the opposite direction to the uphill slide 1312 and being horizontally stuck in the adjacent check position 133, thereby limiting the range of retreat and achieving the effect of energy storage.
[0037] In the first embodiment, the rebound assembly 4 includes a rebound rod 41 hinged to the rebound slide 3 and a rebound rocker 42 elastically hinged to the rebound rod 41. The rebound rocker 42 and the rebound slide 3 are indirectly matched, wherein the rebound rod 41 and the rear end of the rebound slide 3 are hinged through a pin, and the rear end of the rebound rod 41 and the lower end of the rebound rocker 42 are hinged through a pin. In the second embodiment, the rebound assembly 4 includes a rebound rod 41 hinged to the rebound slide 3 and a rebound rocker 42 directly and elastically hinged to the rebound slide 3. The rebound rocker 42 and the rebound slide 3 are directly matched, wherein the rebound rod 41 and the rebound rocker 42 are hinged to the rear end of the rebound slide 3 through a pin.
[0038] In either embodiment 1 or embodiment 2, the box body 1 is formed with a swing rod slideway 12 for guiding the rebound swing rod 42 to cyclically switch between a preset outer swing state and an inner swing state, wherein the swing rod slideway 12 is an annular structure composed of an upper slideway 121 and a lower slideway 122 (with an attached Figure 4 For example, the slide corresponding to the definition point dab is the upper slide 121, and the slide corresponding to the point bcd is the lower slide 122). The rebound swing rod 42 is formed with a guide protrusion 44 that is slidably embedded in the swing rod slide 12. Specifically, when the guide protrusion 44 of the rebound swing rod 42 moves backward along the upper slide 121 (that is, the guide protrusion 44 at this time moves along the dab direction), the corresponding rebound swing rod 42 is guided to be in an outward swing state; conversely, when the guide protrusion 44 of the rebound swing rod 42 moves forward along the lower slide 122 (that is, the guide protrusion 44 at this time moves along the bcd direction), the corresponding rebound swing rod 42 is guided to be in a Inward swing state; secondly, the drawer slide is provided with a rebound collision piece 200 which can touch the rebound rocker rod 42 in the outward swing state. Specifically, the upper end of the rebound rocker rod 42 in the outward swing state is correspondingly located on the moving path of the rebound collision piece 200, so that when the drawer slide is pushed inward, the rebound collision piece 200 touches and pushes the rebound rocker rod 42 in the outward swing state to move backward, so that the rebound slide 3 and the rebound pull rod 41 move backward synchronously therewith; on the contrary, the rebound rocker rod 42 in the inward swing state avoids the rebound collision piece 200 accordingly, so when the drawer slide is pushed inward or pulled outward, the rebound collision piece 200 will not touch the rebound rocker rod 42.
[0039] Furthermore, in order to prevent the rebound rocker arm 42 from retreating to the upper slide 121 due to insufficient thrust during the period when the rebound rocker arm 42 slides and switches from the upper slide 121 to the lower slide 122, a non-rebound spring arm 133 is formed at the tail end of the upper slide 121 of the box body 1, which can cooperate with the guide protrusion 44 for non-rebound. Specifically, the guide protrusion 44 can be pressed and jump over the non-rebound spring arm 123 during the movement along the upper slide 121, and after the guide protrusion 44 completely jumps over the non-rebound spring arm 123 and enters the lower slide 122, the non-rebound spring arm 123 blocks the exit of the upper slide 121. If the guide protrusion 44 retreats in the opposite direction at this time, it will touch the end face of the non-rebound spring arm 123 and cannot cause the non-rebound spring arm 123 to deform and avoid air, thereby achieving a non-rebound effect.
[0040] In either embodiment 1 or embodiment 2, the rebound pull rod 41 is formed with a sliding shaft portion 43 that is slidably embedded in the guide channel 11. In embodiment 1, the sliding shaft portion 43 is provided at the hinge position between the rebound pull rod 41 and the rebound swing rod 42 (the pin shaft here also serves as the sliding shaft portion 43). The guide channel 11 is provided with a fixed resistance block (with an attached) for dividing the guide channel 11 into a lead-in section 111 and a lead-out section 112 that are connected to each other. Figure 4 For example, define point ABD as the lead-in section 111, and DEFA as the lead-out section 112). Specifically, when the rebound rocker arm 42 in the outward swing state is pressed and moves backward (the rebound slide 3 and the rebound pull rod 41 move backward synchronously therewith), the rebound elastic member 32 stores energy and the sliding shaft portion 43 moves synchronously along the lead-in section 111 (that is, the sliding shaft portion 43 at this time moves correspondingly along the ABD direction); conversely, when the rebound rocker arm 42 in the inward swing state is no longer pressed and the rebound elastic member 32 releases energy, the sliding shaft portion 43 moves synchronously along the lead-out section 112 (the rebound slide 3, the rebound rocker arm 42 and the rebound pull rod 41 move forward synchronously) (that is, the sliding shaft portion 43 at this time moves correspondingly along the DEFA direction).
[0041] In this embodiment, the guide channel 11 forms a limiting groove 113 at the junction of the introduction section 111 and the outlet section 112 for blocking the sliding shaft portion 43 from moving forward, wherein the sliding shaft portion 43 can slide into the limiting groove 113 from the introduction section 111 to block the sliding shaft portion 43 from directly moving forward, so that the sliding shaft portion 43 can only move backward to exit the limiting groove 113 and enter the outlet section 112 before it can move forward. Specifically, this embodiment also includes an energy storage slide 6 (the energy storage slide 6 is correspondingly located at the rear position of the rebound component 4) that is directional and slides forward and backward on the box body 1, and the energy storage slide 6 is formed with an upper block 61 and a lower block 62 that extend to the introduction section 111 and the outlet section 112, respectively, wherein the lower block 62 and the fixed block 62 are connected to each other at the introduction section 1 The intersection of the outlet 11 and the entrance of the lead-out section 112 abuts against each other to form a limit groove 113 for blocking the sliding shaft portion 43 from moving forward, and the sliding shaft portion 43 can push the upper block 61 to move backward to avoid the air while sliding along the lead-in section 111, so that the sliding shaft portion 43 slides into the limit groove 113 (at this time, the lower block 62 moves backward synchronously with the energy storage slide 6 and the upper block 61, thereby abutting against the fixed block to form a limit groove); the sliding shaft portion 43 can only move backward to exit the limit groove and enter the lead-out section 112, and the sliding shaft portion 43 can push the lower block 62 to move forward to avoid the air while sliding along the lead-out section 112 (at this time, the upper block 61 moves forward and reset synchronously with the energy storage slide 6 and the upper block 61, thereby having the effect of blocking the sliding shaft portion 43 in the lead-in section 111).
[0042] In this embodiment, a synchronization rod 7 is included which is pivotally connected to the box body 1 and is in transmission cooperation with the energy storage slide 6, wherein the energy storage slide 6 is formed with a straight tooth portion which is meshed and transmitted with a linkage gear preset at the end of the synchronization rod 7. Therefore, in actual use, the two ends of the synchronization rod 7 act on the energy storage slides 6 of the two self-closing buffer rebound boxes respectively, and the rotation action of the synchronization rod 7 is utilized to realize synchronous linkage cooperation between the two self-closing buffer rebound boxes.
[0043] Regardless of the first or second embodiment, the box body 1 is further provided with a rebound avoidance channel (with Figure 4For example, that is, the position indicated by point C, so that when the sliding shaft part 43 slides from the introduction section 111 into the limit groove 113, it needs to move according to the path ABCD). As the sliding shaft part 43 continues to move backward, the sliding shaft part 43 slides from the introduction section 111 into the rebound avoidance channel. At the same time, the rebound rocker arm 42 correspondingly switches from the outward swing state to the inward swing state. Specifically, when the rebound rocker arm 42 of the rebound assembly 4 is continuously pressed and moved backward, the sliding shaft portion 43, the rebound pull rod 41 and the rebound slide 3 move backward synchronously therewith. After the sliding shaft portion 43 pushes away the upper blocking block 61, the sliding shaft portion 43 slides into the rebound avoidance channel from the introduction section 111. At this time, the guide protrusion 44 of the rebound rocker arm 42 is correspondingly switched from the upper slide 121 to the lower slide 122, so that the rebound rocker arm 42 is correspondingly switched to the inner swing state, so as to avoid the preset rebound collision member 200 of the drawer slide rail; when the rebound rocker arm 42 is no longer pressed and moved backward, the rebound elastic member 32 can release energy and drive the rebound slide 3, the rebound pull rod 41 and the rebound rocker arm 42 to move forward synchronously, thereby making the forward movement exit the rebound avoidance channel and enter the limiting groove 113.
[0044] Due to factors such as process or precision, the structure of the self-closing buffer rebound box may have structural error defects, which results in insufficient buffering effect when the drawer is closed, and the drawer kinetic energy cannot be fully absorbed (i.e., the sliding shaft portion 43 does not move in place along the rebound avoidance channel), which causes the drawer to continue to move backward after being closed, thereby triggering the unlocking of the self-closing buffer rebound box and causing the drawer to pop out again. Based on this, it also includes a stopper 9 that is directional and slidingly arranged on the box body 1, wherein the stopper 9 can be normally extended or compressed back relative to the box body 1, that is, as shown in the accompanying drawings, the stopper 9 slides relative to the box body 1 along a direction perpendicular to the sliding direction of the rebound slide 3, so that the top of the stopper 9 extends out to be placed or retracted to avoid the end of the moving path of the rebound bumper 200, so that the rebound bumper 200 can contact with the stopper 9 in the extended state to press the stopper 9 to be compressed back. A stopper elastic member 92 is provided between the stopper 9 and the box body 1, and the elastic force of the stopper elastic member 92 is used to elastically reset the stopper 9 and extend it. In addition, the stopper 9 is integrally formed with a stopper portion 91 which can normally extend into or retract to avoid the rebound avoidance channel, and the stopper portion 91 can positively contact and retract or reversely contact and stop the sliding shaft portion 43 that slides into the rebound avoidance channel, that is, when the stopper 9 is in an extended state, the stopper portion 91 is correspondingly placed in the rebound avoidance channel. At this time, when the sliding shaft portion 43 slides into the rebound avoidance channel from the introduction section 111, the sliding shaft portion 43 contacts the stopper portion 91 for positive contact and retraction, so that the sliding shaft portion 43 can jump over the stopper portion 91 and slide smoothly into the rebound avoidance channel. Subsequently, after the stopper portion 91 is separated from the sliding shaft portion 43, the stopper 91 elastically resets the stopper portion 9 under the elastic force of the stopper elastic member 92, so that the stopper portion 91 normally extends into the rebound avoidance channel to act as a reverse contact stopper on the sliding shaft portion 43, thereby limiting the sliding shaft portion 43 from reversely exiting the rebound avoidance channel.
[0045] In addition, when the rebound collision member 200 jumps over the rebound rocker rod 42 and continues to move backward due to the inertia of the drawer and collides with the stop collision member 9, the stop collision member 9 is pushed and compressed back. At the same time, the stop portion 91 shrinks synchronously with the stop collision member 9 to avoid the empty rebound avoidance channel, so that the sliding shaft portion 43 is no longer restricted and can smoothly exit the rebound avoidance channel in the reverse direction; then, after the inertia of the drawer disappears and under the elastic force of the stop elastic member 92, the rebound collision member 200 will reset and extend into the stop position and push the rebound collision member 200 in turn, so that the stop portion 91 is synchronously reset into the rebound avoidance channel.
[0046] The above-mentioned stop elastic member 92 is a compression spring, and its two ends act on the stop bumper 9 and the box body 1 respectively.
[0047] Regardless of embodiment one or embodiment two, the rebound slide 3 is formed with an elastic portion 31 that contacts the rebound rocker arm 42. The rebound rocker arm 42 tends to swing outward due to the elastic force generated by the elastic portion 31. Specifically, the elastic portion 31 here is a bent spring sheet structure integrally formed at the rear end of the rebound slide 3, thereby generating an elastic force for the rebound slide 3 to swing outward.
[0048] For ease of understanding, the following explanation is given in combination with actual specific application scenarios.
[0049] When closing the drawer: See attached Figure 5-8 As shown, when the user closes the drawer, the drawer slide rail and the self-closing buffer rebound box are both in the open state. Correspondingly, the movable bumper 22 of the self-closing bumper 2 is correspondingly swung into the avoidance groove of the box body 1, and the rebound swing rod 42 is correspondingly in the outward swing state; as the user continues to push the drawer inward, the rebound bumper 200 on the drawer slide rail first touches the upper end of the rebound swing rod 42 in the outward swing state, and pushes the rebound swing rod 42, the rebound pull rod 41 and the rebound slide 3 to move backward synchronously (during this movement, the rebound elastic member 32 stores energy) (that is: Figure 4 The guide protrusion 44 shown in the figure moves along the dab path accordingly), so that the sliding shaft portion 43 moves continuously backward along the introduction section 111 of the guide channel 11 (ie: Figure 4 The sliding shaft portion 43 shown corresponds to the AB path), and then, after the sliding shaft portion 43 touches the top push-up block 61 at the exit position of the introduction section 111, the sliding shaft portion 43 slides from the introduction section 111 into the rebound avoidance channel (ie: Figure 4The sliding shaft portion 43 shown in the figure moves along the BC path), and at the same time, the rebound swing rod 42 swings and switches to the inner swing state to avoid the rebound collision member 200 and is no longer compressed. Then the rebound elastic member 32 releases energy to drive the rebound slide 3, the rebound pull rod 41 and the rebound swing rod 42 to move forward synchronously, so that the sliding shaft portion 43 moves forward to exit the rebound avoidance channel and enter the limit groove 113 (that is: Figure 4 The sliding shaft portion 43 shown corresponds to the CD path movement), and utilizes the blocking effect of the limiting groove 113 to limit the forward movement of the rebound component 4, thereby completing the function of rebound energy storage.
[0050] Then, the rebound collision member 200 jumps over the rebound rocker rod 42 in the inward swing state, and the fixed collision block 100 on the drawer slide rail immediately touches the moving collision block 22 and gradually embeds into the arc-shaped gear, thereby pushing the collision block 22 to swing out of the avoidance groove, and then the self-closing elastic member 5 releases energy to drive the fixed collision block 100, the moving collision block 22 and the self-closing slide 21 to move backward synchronously, thereby driving the drawer slide rail and the drawer to move backward synchronously to achieve the self-closing effect; and during the self-closing period, with the help of the buffering effect of the buffer unit 8 on the self-closing slide 21, the buffering self-closing effect is finally achieved, until the self-closing slide 21 contacts the rebound slide 3, thereby achieving the full closing effect.
[0051] When opening the drawer: There are two ways to open a drawer: one is for the user to directly pull the drawer out to open it, and the other is for the user to press the drawer to rebound and open it. The details are as follows: 1) When the user directly pulls the drawer out to open it, the fixed collision block 100 on the drawer slide rail touches the top push collision block 22 and the self-closing slide 21 moves forward synchronously until the moving collision block 22 swings and gets stuck in the avoidance groove and the fixed collision block 100 is no longer restricted from being separated from the moving collision block 22. At this time, the drawer can be opened freely and the self-closing elastic member 5 is stretched to maintain the energy storage state.
[0052] 2) See attached Figure 9-13 As shown, when the user presses the drawer to rebound and open, the fixed collision block 100 on the drawer slide rail touches the top push collision block 22 and the self-closing slide 21 to move backward synchronously, and the sliding top push rebound slide 3 moves backward, so that the rebound slide 3, the rebound pull rod 41 and the rebound swing rod 42 move backward synchronously, and the sliding shaft part 43 moves backward to exit the limit groove and enter the lead-out section 112 (that is: Figure 4 The sliding shaft portion 43 shown in the figure moves along the DE path), at this time, the sliding shaft portion 43 is out of the limit groove and is no longer restricted, and then the rebound elastic member 32 releases energy to drive the rebound slide 3, the rebound pull rod 41 and the rebound swing rod 42 to move forward synchronously, so that the sliding shaft portion 43 pushes away the lower block 62 (at this time, the lower block 62 moves forward to avoid the moving path of the sliding shaft portion 43) and continues to move along the lead-out section 112 (that is: Figure 4The sliding shaft portion 43 shown corresponds to the EFA path movement), and then, the rebound slide 3 pushes the fixed collision block 100, the movable collision block 22 and the self-closing slide 21 to move forward synchronously until the movable collision block 22 swings and snaps into the avoidance groove of the box body 1 and the fixed collision block 100 disengages from the exit arc gear, thus completing the press-to-rebound-open function.
[0053] At the same time, the guide protrusion 44 of the rebound swing rod 42 continues to move forward along the lower slide path 122 (ie: Figure 4 The guide protrusion 44 shown corresponds to the movement of the bcd path), and after the rebound slide 3 pushes the self-closing slide 21 forward to the rated position (at this time, the movable collision block 22 swings and gets stuck in the avoidance groove), the guide protrusion 44 of the rebound rocker arm 42 moves to the intersection of the lower slide 122 and the upper slide groove, thereby using the elastic force of the elastic part 31 to drive the rebound rocker arm 42 to switch to the outward swing state. At this time, the rebound collision piece 200 of the drawer slide rail corresponds to the rear position of the rebound rocker arm 42, and then as the drawer rebounds and opens, the rebound collision piece 200 will touch the back of the rebound rocker arm 42 to force the rebound rocker arm 42 to overcome the elastic force of the elastic part 31 and swing inward to avoid, until the rebound collision piece 200 moves completely forward and jumps over the rebound rocker arm 42, thus completing the drawer opening function; then, after the rebound rocker arm 42 is no longer under pressure, the elastic force of the elastic part 31 will drive the rebound rocker arm 42 to switch to the outward swing state.
[0054] At the same time, when the self-closing slide 21 moves forward, the telescopic rod of the buffer unit 8 extends forward accordingly.
[0055] In summary, the drawer opening function can be realized through the above two methods, ensuring the smoothness, convenience and safety of the drawer operation. The following are the specific advantages: 1. Synchronous linkage: The synchronous linkage between the two self-closing buffer rebound boxes is achieved by meshing the synchronous rod 7 pivoted on the box body 1 with the spur gear portion of the energy storage slide 6. This means that during operation, whether closing or opening the drawer, the two self-closing buffer rebound boxes can respond at the same time, ensuring the coordination and consistency of the drawer action.
[0056] 2. The elastic part 31 cooperates with the rebound swing rod 42: The elastic part 31 formed on the rebound slide 3 generates an elastic force on the rebound swing rod 42, causing it to swing outward. This design ensures that the rebound swing rod 42 can automatically return to the outward swing state when not under pressure, preparing for the next rebound opening of the drawer.
[0057] 3. Multiple opening methods: The drawer can be opened by the user directly pulling the drawer outward, or by the user pressing the drawer to rebound and open. The flexibility of this design allows users to choose the appropriate opening method according to their own usage habits, which improves the usability of the drawer.
[0058] 4. Compact structure and integrated functions: The entire design integrates multiple functions such as synchronous linkage, rebound avoidance, elastic recovery, buffer self-closing, etc. into a compact structure, making the drawer convenient and safe to operate.
[0059] To sum up, this design achieves smoothness, convenience and safety of drawer operation through carefully designed structure and function, bringing a better user experience.
