Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, specifically a synchronous slide rail with buffering and rebound functions. Background Technology

[0002] Synchronous concealed slides are widely used in furniture drawers and other similar applications. However, existing synchronous slides generally offer only a single function, such as buffering or rebound, which still falls short in terms of user experience.

[0003] Currently common drawer slides lack cushioning at the end of the closing process, resulting in a large impact force and high noise when closing, affecting service life and user experience. Although some drawer slides add buffers (such as dampers), they usually only have a single cushioning closing function and cannot achieve automatic rebound opening. To achieve the "press to automatically open" function, the drawer slide needs to be equipped with a press-to-rebound device, which is located on the left and right sides of the drawer slide. A synchronous running component is installed between the press-to-rebound device and the drawer slide. The press-to-rebound device stores energy when the slide is closed and leaves space for pressing to unlock. When the drawer is pressed, the drawer unlocks and rebounds, realizing the automatic pop-out of the pull-out furniture, which is convenient to operate.

[0004] However, existing rebound rails require abandoning the closing buffer function, making them difficult to integrate effectively with synchronization systems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a synchronous slide rail with buffering and rebound functions. It has a compact structure, runs smoothly, and integrates two modes: buffering closure and pressing rebound. It can flexibly switch between modes, is easy to operate, has reliable and practical performance, and ensures a good user experience.

[0006] The objective of this invention is achieved as follows: A synchronous slide rail with buffering and rebound functions includes slide rail components installed on both sides of a drawer, a press-and-rebound component with a press-and-rebound function, and a buffer component with a buffer closing function. The buffer component is installed on the fixed rail of the slide rail component. The movable rail of the slide rail component is engaged with or disengaged from the damper of the buffer component as it opens and closes. The press-and-rebound component includes a fixed seat installed on the fixed rail, an energy storage sliding assembly for pushing and storing energy, and a press-and-release assembly. The energy storage sliding assembly is provided with a toggle member that links the energy storage sliding assembly to slide on the fixed seat. The toggle member is slidably connected to the fixed seat and engaged with or disengaged from the movable rail. The fixed seat is provided with a linkage protrusion. The energy storage sliding assembly is provided with a retractable elastic stop and a recess that can be directionally slidably connected to one side of the linkage protrusion as it opens and closes. The linkage protrusion and the fixed seat form a circulating sliding groove for the elastic stop to extend elastically and be linked with the toggle member, or for compressing the elastic stop and separating it from the toggle member without interference. The elastic stop is provided with a linkage shaft that slides slidably connected to the circulating sliding groove as it extends and retracts.

[0007] Based on the above-mentioned optimization, the fixed base is provided with a linear guide groove for the linear sliding of the energy storage sliding component. The linear guide groove is connected to a rebound Y-shaped guide groove for the directional movement of the press-release energy component, which swings and locks under the elastic action of the energy storage sliding component, slides away to unlock, and moves and resets under the elastic action of the energy storage sliding component. The press-release energy component includes a swing pin that is shaft-connected to the energy storage sliding component. The swing pin moves with the energy storage sliding component and slides forward in the rebound Y-shaped guide groove, locks or resets and slides backward.

[0008] Based on the above-mentioned optimization, the press-release energy component also includes a deceleration component with a buffer function. The deceleration component includes a deceleration mounting base and a deceleration wheel. The deceleration mounting base is installed at the front end of the fixed base. During the energy storage of the energy storage sliding component, the deceleration wheel is pushed by the swinging component of the press-release energy component to rotate and rub against the deceleration mounting base.

[0009] Based on the above optimization, the fixed base is provided with a snap-on post that can be detached from the deceleration mounting base, the deceleration mounting base is provided with a rotating post that is rotatably frictionally connected to the deceleration mounting base, and the deceleration wheel is mounted on the rotating post.

[0010] Based on the above optimization, the fixed base is provided with a synchronization component for the simultaneous locking and unlocking of the slide rail components on both sides. The synchronization component includes a synchronization slider, a synchronization trigger shaft, and a synchronization shaft. The synchronization slider is slidably mounted on the fixed base and can be moved downwards on the fixed base in conjunction with the press-release energy component. The two ends of the synchronization shaft are respectively fitted and inserted into the corresponding synchronization trigger shafts on both sides of the drawer. The synchronization trigger shaft is locked onto the synchronization slider and can swing back and forth as the synchronization slider slides.

[0011] Based on the above-mentioned row-by-row optimization, the synchronous slider is provided with a reset elastic element that can be reset forward. One elastic end of the reset elastic element is locked onto the fixed base, and the other elastic end of the reset elastic element is locked onto the synchronous slider.

[0012] Based on the above optimization, the energy storage sliding assembly includes an energy storage slider and an energy storage spring. The energy storage slider is slidably connected to the fixed base. One elastic end of the energy storage spring is clamped to the energy storage slider, and the other elastic end of the energy storage spring is clamped to the fixed base. One end of the energy storage slider is connected to the swing needle, and an elastic stop is installed inside the energy storage slider.

[0013] Based on the above optimization, the fixed base is provided with a directional protrusion for linear reciprocating sliding of the energy storage slider, and the linear guide groove is provided on the directional protrusion.

[0014] Based on the above-mentioned optimization, the fixed base is provided with a mounting bracket for the movable rail of the slide rail component that can be detached and installed. The mounting bracket is provided with a position adjustment component for adjusting the installation position between the fixed base and the mounting bracket. The position adjustment component includes an adjustment wheel and an adjustment flange. The adjustment flange is longitudinally distributed on the mounting bracket. The adjustment wheel is rotatably connected to the fixed base, and one side of the adjustment wheel is provided with a helical flange. The helical flange rotates with the adjustment wheel so that the adjustment flange is screwed into or out of the helical flange.

[0015] The advantages of this utility model are:

[0016] Through the coordinated structure of the pressing and rebound component's fixing base, energy storage sliding component, and pressing and releasing component, when the drawer is pressed and the slide rail component closes, the energy storage sliding component moves along the circulating sliding groove. The elastic stop extends elastically and connects with the actuating component, achieving initial energy storage. Upon reaching the designated position, the energy storage sliding component completes its energy storage, the elastic stop compresses and separates from the actuating component without interference, the buffer component operates, achieving a closing buffer function, and the slide rail component automatically resets. The design is compact, operates smoothly, and integrates both buffer closing and pressing and rebound modes, allowing for flexible switching between modes. It is easy to operate, reliable and practical, ensuring a superior user experience. Attached Figure Description

[0024] The present invention will now be further described with reference to the accompanying drawings.

[0025] According to the appendix Figures 1 to 7 As shown, the present invention discloses a synchronous slide rail with buffering and rebound functions, comprising a slide rail component 1 installed on both sides of a drawer, a press-to-rebound component with a press-to-rebound function, and a buffer component 2 with a buffer closing function. The buffer component 2 is installed on the fixed rail of the slide rail component 1, and the movable rail of the slide rail component 1 is engaged with or disengaged from the damper of the buffer component 2 as it opens and closes. The press-to-rebound component includes a fixed base 3 installed on the fixed rail, an energy storage sliding assembly 4 for pushing and storing energy, and a press-to-release assembly 5. The energy storage sliding assembly 4 is provided with an actuating element 14 for sliding on the fixed base 3, and the actuating element 14 is slidably connected to the fixed base 3 while being engaged with or disengaged from the movable rail. The fixed base 3 is provided with a linkage protrusion 31, and the energy storage sliding assembly 4 is provided with a retractable elastic stop 6 and a recess 43 that is directionally slidably connected to one side of the linkage protrusion 31 as it opens and closes. Furthermore, the linkage protrusion 31 and the fixed base 3 form a circulating sliding groove 7 for the elastic stop 6 to extend elastically and be linked with the actuating member 14, or for compressing the elastic stop 6 and separating it from the actuating member 14 without interfering with each other. The elastic stop 6 is provided with a linkage shaft 61 that slides and connects with the circulating sliding groove 7 as it extends and retracts.

[0026] When the drawer is pressed, the slide rail component 1 closes. The energy-storing sliding component 4 moves along the circulating sliding groove 7, and the elastic stop 6 extends elastically and is linked with the actuating component 14 to achieve initial force storage. After reaching the designated position, the energy-storing sliding component 4 completes its force storage. The elastic stop 6 is compressed under the action of the linkage protrusion 31 and separates from the actuating component 14 without interfering with each other. The buffer component 2 works to achieve the closing buffer function, and the slide rail component 1 automatically resets. It integrates two modes: buffer closing and press rebound, and can flexibly switch between the two modes. It has a compact structure, runs smoothly, is easy to operate, and has reliable and practical performance, ensuring a good user experience.

[0027] Reference Figures 1 to 7As shown in the figure, further detailed, the fixed base 3 is provided with a linear guide groove 11 for linear sliding of the energy storage sliding component 4. The linear guide groove 11 is connected to a rebound Y-shaped guide groove 8 for directional movement of the press-release energy component 5, which swings and locks under the elastic action of the energy storage sliding component 4, is pushed away to unlock, and moves and resets under the elastic action of the energy storage sliding component 4. The press-release energy component 5 includes a swing pin 51 axially connected to the energy storage sliding component 4. The swing pin 51 moves forward, locks, or resets and slides backward in the rebound Y-shaped guide groove 8 as the energy storage sliding component 4 moves.

[0028] The energy storage sliding assembly 4 includes an energy storage slider 41 and an energy storage spring 42. The energy storage slider 41 is slidably connected to the fixed base 3. One elastic end of the energy storage spring 42 is clamped to the energy storage slider 41, and the other elastic end of the energy storage spring 42 is clamped to the fixed base 3. One end of the energy storage slider 41 is connected to the swing needle 51. An elastic stop block 6 is installed inside the energy storage slider 41.

[0029] During this period, the fixed base 3 is provided with a directional protrusion for the linear reciprocating sliding of the energy storage slider 41, and the linear guide groove 11 is provided on the directional protrusion.

[0030] That is, when the drawer is pushed to close, the movable rail of the slide rail component 1 engages with the actuating pin, thereby linking the energy storage sliding component 4 and causing the energy storage slider 41 to move forward along the directional protrusion. The elastic stop 6 slides along the linkage protrusion 31 through the recess 43, and under the elastic action of the elastic stop 6, the linkage shaft 61 slides along one side of the circulating sliding groove 7. At this time, the swing pin 51 of the press-release component 5 moves along the Y-shaped guide groove, and under the elastic action of the energy storage spring 42, the swing pin 51 is pulled and locked into the inner recess of the Y-shaped guide groove, and the energy storage sliding component 4 is locked to complete the power storage. During this period, the linkage shaft 61 slides to the other side of the circulating sliding groove 7, and the elastic stop 6 is compressed into the energy storage slider 41 by the linkage protrusion 31, so that the elastic stop 6 and the actuating component 14 are separated and do not interfere with each other, so that the press-rebound component is in the power storage state, while the buffer component 2 continues to be compressed as the slide rail component 1 closes, and the buffer component 2 works to realize the buffer closure of the slide rail component 1.

[0031] Reference Figures 1 to 7 As shown, further detailed, the press-release energy component 5 also includes a deceleration component 9 with a buffer function. The deceleration component 9 includes a deceleration mounting base 91 and a deceleration wheel 92. The deceleration mounting base 91 is installed at the front end of the fixed base 3. During the energy storage of the energy storage sliding component 4, the deceleration wheel 92 is pushed by the swinging component of the press-release energy component 5 to rotate and rub against the deceleration mounting base 91.

[0032] In the optimized solution, the fixed base 3 is provided with a snap-on post that can be detached from the deceleration mounting base 91, the deceleration mounting base 91 is provided with a rotating post 93 that is rotatably frictionally connected to the deceleration mounting base 91, and the deceleration wheel 92 is mounted on the rotating post 93.

[0033] During energy storage, the swing needle 51 moves forward along the rebound Y-shaped guide groove 8 under the action of the pushing force, and falls back under the elastic tension of the energy storage spring 42 of the energy storage sliding component 4. During this period, the swing needle 51 contacts the reduction wheel 92 and pushes the reduction wheel 92 to rotate. Since the reduction wheel 92 and the reduction mounting seat 91 are connected by dynamic friction, the falling speed of the swing needle 51 is effectively slowed down, reducing noise generation and allowing the swing needle 51 to be precisely locked on the inner concave part of the Y-shaped guide groove, realizing the locking of the energy storage sliding component 4 and completing the energy storage. The structure is simple, reduces noise, and avoids failure of the press-rebound component.

[0034] Reference Figures 1 to 7 As shown in the figure, further detailed, the fixed base 3 is provided with a synchronization component 10 for the simultaneous locking and unlocking of the slide rail components 1 on both sides. The synchronization component 10 includes a synchronization slider 101, a synchronization trigger shaft 102, and a synchronization shaft. The synchronization slider 101 is slidably mounted on the fixed base 3 and can be moved downwards on the fixed base 3 in conjunction with the press-release energy component 5. The two ends of the synchronization shaft are respectively fitted into the corresponding synchronization trigger shafts 102 on both sides of the drawer. The synchronization trigger shaft 102 is snapped onto the synchronization slider 101 and can swing back and forth as the synchronization slider 101 slides.

[0035] The synchronous slider 101 is provided with a reset elastic element 103 that can be reset forward. One elastic end of the reset elastic element 103 is attached to the fixed base 3, and the other elastic end of the reset elastic element 103 is attached to the synchronous slider 101.

[0036] When the drawer is pressed, the swing pin 51 disengages from the recessed part of the Y-shaped guide groove and slides backward along the Y-shaped guide groove under the action of the energy storage spring 42, thereby unlocking the energy storage sliding component 4. At the same time, the swing pin 51 connects with the synchronous slider 101 and moves the synchronous slider 101 backward, thereby unlocking and opening the slide rail components 1 on both sides simultaneously. During this process, the energy storage slider 41 resets, and the linkage shaft 61 also slides along the circulating sliding groove 7 to the reset position, thus automatically ejecting the movable rail. In this way, the linkage of rebound, synchronization, and buffering functions is achieved through a mechanical structure, resulting in high stability and a long service life.

[0037] Reference Figures 1 to 7As shown in the figure, further detailed, the fixed base 3 is provided with a mounting bracket 12 for the movable rail of the slide rail component 1 that can be detached and installed. The mounting bracket 12 is provided with a position adjustment component 13 for adjusting the installation position between the fixed base 3 and the mounting bracket 12. The position adjustment component 13 includes an adjustment wheel 131 and an adjustment flange 132. The adjustment flange 132 is longitudinally distributed on the mounting bracket 12. The adjustment wheel 131 is rotatably connected to the fixed base 3, and a spiral flange 133 is provided on one side of the adjustment wheel 131. The spiral flange rotates with the adjustment wheel 131 so that the adjustment flange 132 is screwed into or out of the spiral flange.

[0038] By rotating the adjusting wheel 131 under the action of the position adjustment component 13, the assembly position between the fixed seat 3 and the mounting bracket 12 can be adjusted, which strengthens the structural connection stability and improves the assembly accuracy.
