Description

Technical Field

[0001] The present invention relates to a slide rail, and more particularly to a slide rail having a press-and-rebound and damping-closure function. Background Art

[0002] In order to improve the convenience and safety of the opening and closing operations of slide rails for furniture, cabinets, drawers, etc., many functional accessories for such slide rails have emerged on the market. Common functional accessories include damping devices and press-and-rebound devices. The damping device stores energy when the slide rail is opened and automatically slowly pulls the slide rail back to the closed position after the slide rail is closed to a certain extent, enabling the buffered closing of drawer-like pull-out furniture. The press-and-rebound device stores energy when the slide rail is closed and leaves a space for pressing to unlock. By pressing the drawer-like pull-out furniture, it is unlocked and rebounds, realizing the automatic springing open of the pull-out furniture.

[0003] Based on the above working principles of the damping device and the press-and-rebound device, if one wants to simultaneously achieve the damping-closure and press-and-rebound functions on the slide rail, the damping device and the press-and-rebound device need to be stably coordinated in terms of structure and function. Common rebound-damping slide rails respectively install the rebound device and the damping device on the slide rail. Due to factors such as installation and processing errors, it is usually necessary to adjust the relative positions of the rebound device and the damping device on the slide rail to ensure their stable coordination in function, which increases the assembly process, and it is not easy to ensure the coordination stability of the damping-closure and press-and-rebound functions, which is not conducive to the consistency of the product. In view of the above problems, Chinese Patent Application No. 202410971901.9 discloses a technical solution with the patent name "A Press-and-Rebound Damping Slide Rail". Specifically, by using the cooperation of the transmission gear and the clutch mechanism in the gearbox, as well as the cooperation between the gearbox and the self-closing spring seat, the conversion of press-and-rebound elastic energy storage / release and damping-closure elastic energy storage / release is achieved. During the press-and-rebound process, the transmission gear can drive the rack on the movable rail to rebound together, and at the same time, the self-closing spring seat can move along with the gearbox towards the proximal direction of the self-closing damping bracket, without hindering the press-and-rebound function; at the initial stage of the slide rail closing, the press-and-rebound and damping-closure elastic energy storage can be completed simultaneously, and the slide rail can be freely pushed and pulled through the forward and reverse rotation of the transmission gear. After the slide rail is closed, the damping-closure mechanism can be used to automatically drive the slide rail to close. This press-and-rebound damping device organically combines the damping-closure and press-and-rebound functions, so that the coordination stability between the two will not be reduced due to factors such as installation errors. However, considering factors such as manufacturing costs, the structure and implementation principle of the above press-and-rebound damping device are relatively complex. Especially, there are many components required inside the gearbox, and a long-sized transmission rack needs to be set on the slide rail, resulting in a relatively high manufacturing cost of the slide rail; moreover, more moving parts and complex structures are also likely to increase the failure rate and affect the service life. Summary of the Invention

[0004] 1. Technical problem to be solved by the invention

[0005] The object of the present invention is to overcome the deficiencies of the existing press - rebound damping slide rail, such as complex structure and high manufacturing cost, and provide a slide rail with press - rebound and damping self - closing functions. By adopting the technical solution of the present invention, the rebound component and the damping self - closing component are integrated on the same base, and are respectively matched with the rebound dial pin and the self - closing dial pin on the movable rail. By using the structural cooperation of the rebound component and the damping self - closing component, it is realized that during the rebound and damping self - closing processes of the slide rail, the force transmission can be achieved through the self - closing chuck of the damping self - closing component, so that the rebound component only needs to be responsible for rebound triggering and closing energy storage. Furthermore, the structure of the rebound component is simplified, the manufacturing difficulty and manufacturing cost are reduced, and the structural compactness of the press - rebound damping slide rail is further improved.

[0006] 2. Technical solution

[0007] To achieve the above object, the technical solution provided by the present invention is as follows:

[0008] A slide rail with press - rebound and damping self - closing functions of the present invention includes a slide rail assembly and a rebound damping device. The slide rail assembly includes a fixed rail and a movable rail that can slide relative to the fixed rail. The rebound damping device includes a base, a rebound component and a damping self - closing component respectively arranged on the base. The base is installed on the fixed rail. The movable rail is provided with a rebound dial pin that cooperates with the rebound component and a self - closing dial pin that cooperates with the damping self - closing component; wherein:

[0009] The base is provided with a track groove and a rebound trigger block. The rebound trigger block has a trigger part that cooperates with the rebound dial pin and a dial - pin limiting part that extends to the track groove. The rebound trigger block can move relative to the track groove through the pressing action of the movable rail, so that the dial - pin limiting part releases the blockage of the rebound path of the track groove;

[0010] The rebound component includes a sliding seat and a rebound spring. The sliding seat is slidably arranged on the base. The rebound spring is installed between the sliding seat and the base to apply a rebound force to the sliding seat. A sliding dial pin that can move sequentially in the track groove is arranged in the sliding seat. The sliding dial pin can be blocked and locked by the above - mentioned dial - pin limiting part and is released for rebound when the rebound trigger block moves under the pressing action of the rebound dial pin. A pushing mechanism is further arranged on the sliding seat. The pushing mechanism can be driven by the rebound dial pin to drive the sliding seat to move in the direction where the above - mentioned dial - pin limiting part is located when the movable rail is closed, and is disengaged from the rebound dial pin when the sliding dial pin is blocked and locked by the above - mentioned dial - pin limiting part;

[0011] The damping self-closing component includes a self-closing spring seat, a damper, a self-closing chuck and a self-closing spring. The self-closing spring seat is slidably arranged on the base and connected to the above-mentioned sliding seat. One end of the self-closing spring is connected to the self-closing spring seat, and the other end is connected to the self-closing chuck. The damper is installed on the base and connected to the self-closing chuck. The self-closing chuck can be locked on the base at a position away from the dial pin limiting part, and is unlocked and combined with the self-closing dial pin when the movable rail is closed, so as to drive the movable rail to move and close in the opposite direction of the rebound direction under the combined action of the damper and the self-closing spring. When the sliding seat unlocks and rebounds, the sliding seat drives the self-closing chuck and the movable rail to rebound together through the self-closing spring seat.

[0012] Further, the pushing mechanism includes a swing arm, a telescopic block and a compression spring. One end of the swing arm is rotatably installed in the sliding seat, and the sliding dial pin is installed on the swing arm, so that the swing arm makes a yawing motion as the position of the sliding dial pin in the track groove changes. The telescopic block is movably arranged on one side of the swing arm, and the compression spring is arranged between the telescopic block and the swing arm, so that the telescopic block maintains an elastic tendency to extend outward from the swing arm. A notch for the telescopic block to extend out is also provided on one side of the sliding seat.

[0013] The track groove includes a closing guide groove, a rebound guide groove and a transition guide groove. The dial pin limiting part is located at the transition guide groove. When the sliding dial pin is in the closing guide groove, the telescopic block extends outward with the swing arm to be combined with the rebound dial pin and move therewith in the closing moving direction of the movable rail. When the sliding dial pin is in the transition guide groove and the rebound guide groove, the telescopic block swings inward with the swing arm and disengages from the rebound dial pin.

[0014] Further, the extending end of the telescopic block has an avoidance inclined surface arranged towards the rebound direction of the movable rail. When the movable rail rebounds and opens, the rebound dial pin cooperates with the avoidance inclined surface to press the telescopic block to contract inward, so that the rebound dial pin can cross over the telescopic block.

[0015] Further, the closing guide groove and the transition guide groove are connected by a guiding arc. When the rebound dial pin pushes the telescopic block to move in the closing moving direction of the movable rail, the sliding dial pin is guided by the guiding arc into the transition guide groove and drives the telescopic block to generate an inward yawing inclination, so that the rebound dial pin presses the telescopic block to contract and cross over the telescopic block.

[0016] Furthermore, a first return spring is provided between the rebound trigger block and the base to enable the pin limiting portion to have an elastic tendency to remain in the transition guide groove; a blocking block is also movably provided on the base, one end of the blocking block has a guiding inclined surface located in the rebound guide groove, and when the blocking block moves in the rebound direction, the guiding inclined surface forms a return channel connecting the rebound guide groove and the closing guide groove; a second return spring is also provided between the blocking block and the base to enable the blocking block to maintain an elastic tendency to close the return channel.

[0017] Furthermore, the end of the pin limiting portion is in a concave arc shape, and this concave arc shape is used to guide the sliding pin from the transition guide groove to the rebound guide groove; when the pin limiting portion extends into the transition guide groove, the sliding pin is blocked and locked by the reduction of the size of the transition guide groove.

[0018] Furthermore, the rebound damping device further includes a synchronization component, the synchronization component includes a synchronization gear, a connecting member and a synchronization transmission rod, the synchronization gear is rotatably installed on the base, the rebound trigger block has a rack meshing with the synchronization gear, and the synchronization gear is coaxially connected to the synchronization transmission rod through the connecting member; when the rebound trigger block moves under the pressing action of the rebound pin, the synchronization transmission rod is driven to rotate through the meshing transmission of the rack and the synchronization gear.

[0019] Furthermore, the rebound component and the damping self-closing component are respectively arranged on opposite surfaces of the base, the self-closing spring seat slides in the spring seat sliding groove of the base, the self-closing spring seat is provided with a boss, and this boss passes through the base and is connected to the jack on the sliding seat; the self-closing chuck is connected to the damper and the self-closing spring through the self-closing slider, the self-closing chuck is rotatably installed on the self-closing slider, the base has a guiding rib slidably matched with the self-closing chuck, one end of the guiding rib away from the pin limiting portion has a corner, and the self-closing chuck has an arc groove matched with the corner. When the self-closing chuck is pulled by the self-closing pin and moves towards the corner, the self-closing chuck rotates along the corner under the action of an eccentric pulling force and is buckled with the corner and separated from the self-closing pin.

[0020] Furthermore, a switching plug for locking or unlocking the rebound trigger block is also provided on one side of the base close to the rebound trigger block. When the switching plug locks the rebound trigger block, the pin limiting portion remains in the track groove and cannot be pressed to rebound; when the switching plug unlocks the rebound trigger block, the rebound trigger block can be normally pressed to achieve unlocking and rebounding.

[0021] Furthermore, a locking groove is provided on the rebound trigger block, the switching plug is detachably installed on the side wall of the base, and the switching plug has a plug head corresponding to the position of the above-mentioned locking groove. A positioning structure is also provided between the switching plug and the base.

[0022] 3. Beneficial effects

[0023] Adopting the technical solution provided by the present invention, compared with the existing well-known technologies, it has the following remarkable effects:

[0024] (1) A slide rail with a press-and-rebound and damping self-closing function according to the present invention includes a slide rail assembly and a rebound damping device. The rebound damping device includes a base, and a rebound assembly and a damping self-closing assembly respectively arranged on the base. A rebound dial pin cooperating with the rebound assembly and a self-closing dial pin cooperating with the damping self-closing assembly are arranged on the movable rail. The rebound assembly and the damping self-closing assembly are designed on the same base and organically combined, improving the cooperation stability between the two. Among them, a track groove and a rebound trigger block are arranged on the base. The rebound assembly includes a sliding seat and a rebound spring. A sliding dial pin capable of sequentially moving in the track groove is arranged in the sliding seat. The sliding dial pin can be blocked and locked by the above-mentioned dial pin limiting part, and is released and rebounds when the rebound trigger block moves under the pressing action of the rebound dial pin. The damping self-closing assembly includes a self-closing spring seat, a damper, a self-closing chuck and a self-closing spring. The self-closing spring seat is slidably arranged on the base and is connected to the above-mentioned sliding seat, so that the sliding seat and the self-closing spring seat move synchronously. By using the structural cooperation of the rebound assembly and the damping self-closing assembly, it is realized that the force transmission can be achieved through the self-closing chuck of the damping self-closing assembly during both the rebound and damping self-closing processes of the slide rail, so that the rebound assembly only needs to be responsible for rebound triggering and closing energy storage, thereby simplifying the structure of the rebound assembly, reducing the manufacturing difficulty and manufacturing cost, and further improving the structural compactness of the press-and-rebound damping slide rail;

[0025] (2) In a slide rail with a press-and-rebound and damping self-closing function according to the present invention, the pushing mechanism in the rebound assembly includes a swing arm, a telescopic block and a compression spring. The sliding dial pin is installed on the swing arm, so that the swing arm makes a yaw movement with the change of the position of the sliding dial pin in the track groove. The telescopic block is movably arranged on one side of the swing arm. When the sliding dial pin is in the closing guide groove, the telescopic block extends outwards with the swing arm to be combined with the rebound dial pin and move therewith in the closing moving direction of the movable rail. When the sliding dial pin is in the transition guide groove and the rebound guide groove, the telescopic block swings inwards with the swing arm and disengages from the rebound dial pin, avoiding the interference of the telescopic block on the damping self-closing and rebound opening of the moving member. By adopting the above-mentioned pushing mechanism, the structure is simple and compact, the manufacturing and assembly are convenient, and the movement is stable and reliable;

[0026] (3) In a slide rail with a press-and-rebound and damping self-closing function according to the present invention, the extending end of the telescopic block has an avoidance inclined surface arranged towards the rebound direction of the movable rail. During the rebound opening process, when the moving member contacts the avoidance inclined surface, it can provide a pressing force to the telescopic block to cause it to contract, so that the moving member can easily cross the telescopic block, ensuring the reliability and smoothness of the rebound;

[0027] (4) A slide rail with a pressing rebound and damping closing function according to the present invention has a guiding arc connecting the closing guide groove and the transition guide groove. When the rebound trigger pin pushes the telescopic block to move along the closing direction of the movable rail, the sliding trigger pin is guided by the guiding arc and enters the transition guide groove, driving the telescopic block to generate an inward deflection and tilt, causing the rebound trigger pin to compress the telescopic block and make it contract so as to cross the telescopic block. The design of the guiding arc, on the one hand, enables the sliding trigger pin to smoothly and stably enter the transition guide groove from the closing guide groove, and on the other hand, can realize the separation of the rebound trigger pin and the telescopic block through the deflection of the swing arm, ensuring the stability and reliability of the pressing rebound and damping closing functions of the slide rail;

[0028] (5) A slide rail with a pressing rebound and damping closing function according to the present invention is provided with a first return spring between the rebound trigger block and the base, so as to make the trigger pin limiting part have an elastic tendency to stay in the transition guide groove, ensuring the stability of the reset action of the rebound trigger block; A blocking block is also movably arranged on the base. One end of the blocking block has a guiding slope located in the rebound guide groove. When the blocking block moves in the rebound direction, the guiding slope forms a reset channel connecting the rebound guide groove and the closing guide groove. This blocking block closes the reset channel between the rebound guide groove and the closing guide groove during the closing process of the movable rail, ensuring that the sliding trigger pin can stably and sequentially move in the track groove, preventing the sliding trigger pin from mistakenly entering the closing guide groove and causing the premature separation of the movable rail and the telescopic block. At the same time, during the rebound opening process of the movable rail, the sliding trigger pin can push the blocking block away for reset; In addition, a second return spring is also provided between the blocking block and the base to make the blocking block maintain an elastic tendency to close the reset channel. During the rebound opening process, the blocking block can play a certain buffering role on the sliding trigger pin, effectively preventing the collision between the sliding seat and the base;

[0029] (6) A slide rail with a pressing rebound and damping closing function according to the present invention has the end of the trigger pin limiting part in an inward concave arc shape, which is used to guide the sliding trigger pin from the transition guide groove to the rebound guide groove; When the trigger pin limiting part extends into the transition guide groove, the sliding trigger pin is blocked and locked by the reduction of the size of the transition guide groove; With the above design of the trigger pin limiting part, it can not only guide the sliding trigger pin, but also block and lock the sliding trigger pin. The structure design is simple, and the guiding and locking of the sliding trigger pin are stable and reliable;

[0030] (7) A slide rail with a pressing rebound and damping closing function according to the present invention, its rebound damping device further includes a synchronization component. The synchronization component includes a synchronization gear, a connecting piece and a synchronization transmission rod. The rebound trigger block has a rack meshing with the synchronization gear. Using the pressing trigger movement of the rebound trigger block to drive the synchronization transmission rod to rotate, the structure is simple, the transmission is stable, and the synchronization of the pressing rebound actions of two groups of slide rails can be realized;

[0031] (8) A slide rail of the present invention with a press-and-rebound and damping-closure function, in which its rebound component and damping self-closure component are respectively arranged on opposite surfaces of the base, further improving the structural compactness of the press-and-rebound damping device, reducing its overall size, and enhancing the installation applicability of the press-and-rebound damping device; in addition, the base is provided with guide ribs that slidably cooperate with the self-closure chuck, one end of the guide rib away from the needle-pushing limit portion has a corner, and the self-closure chuck is provided with an arc groove that cooperates with the corner. When the self-closure chuck is pulled by the self-closure needle-pusher and moves towards the corner, the self-closure chuck rotates along the corner under the action of eccentric tension, engages with the corner, and separates from the self-closure needle-pusher, realizing the combination or separation between the self-closure chuck and the movable rail and the locking or unlocking between the self-closure chuck and the guide rib. The structure is simple and the conversion is stable;

[0032] (9) A slide rail of the present invention with a press-and-rebound and damping-closure function, and a switching plug for locking or unlocking the rebound trigger block is also provided on one side of the base close to the rebound trigger block. When the switching plug locks the rebound trigger block, the needle-pushing limit portion remains in the track groove and cannot be pressed and rebounded; when the switching plug unlocks the rebound trigger block, the rebound trigger block can be normally pressed to achieve unlocking and rebounding; the use of the switching plug can prevent the slide rail from being accidentally triggered to cause rebound and pop out, such as popping out under non-subjective pressing conditions such as handling, transportation, and accidental collision; when the pressing function is restricted by the switching plug, the slide rail can be pulled open and can also be normally closed. Therefore, it can be used as a normal damping slide rail; that is to say, this slide rail has both a rebound function and a damping self-closure function, can meet two usage scenarios, and can be freely switched; in addition, the switching plug has a simple structure and is convenient to operate.

[0056] To further understand the content of the present invention, the present invention will be described in detail in combination with the drawings and embodiments.

[0057] [Embodiment]

[0058] Combined with Figure 1 and Figure 2 As shown, a slide rail with a pressing rebound and damper closing function in this embodiment includes a slide rail assembly 8 and a rebound damper device. The rebound damper device is installed on the slide rail assembly 8, so that the slide rail has a pressing rebound and damper closing function. The above slide rail assembly 8 mainly includes a fixed rail 81 and a movable rail 82 that can slide relative to the fixed rail 81. The sliding fit structure between the movable rail 82 and the fixed rail 81 is similar to the prior art and will not be elaborated here. An intermediate rail 83 can also be provided between the movable rail 82 and the fixed rail 81 to form a three-section slide rail structure. The above rebound damper device includes a base seat 2, and a rebound assembly 4 and a damper self-closing assembly 5 respectively arranged on the base seat 2. The base seat 2 is installed on the fixed rail 81, and a rebound dial pin 82a that cooperates with the rebound assembly 4 and a self-closing dial pin 82b that cooperates with the damper self-closing assembly 5 are provided on the movable rail 82.

[0059] Among them, referring toFigure 10 As shown in the figure, the base 2 is provided with a track groove 2-1 and a rebound trigger block 21. The rebound trigger block 21 has a trigger portion 21-1 that cooperates with the rebound push pin 82a and a push pin limiting portion 21-2 that extends into the track groove 2-1. The rebound trigger block 21 can move relative to the track groove 2-1 through the pressing action of the movable rail 82, so that the push pin limiting portion 21-2 releases the blockage of the rebound path of the track groove 2-1. Specifically, when the pressing action causes the movable rail 82 to drive the rebound push pin 82a to move, the rebound push pin 82a drives the trigger portion 21-1 to move, thereby driving the push pin limiting portion 21-2 to move to release the blockage of the rebound path of the track groove 2-1, realizing the unlocking of the pressing and rebounding action.

[0060] The rebound assembly 4 includes a sliding seat 41 and a rebound spring 42. The sliding seat 41 is slidably arranged on the base 2. The rebound spring 42 is installed between the sliding seat 41 and the base 2 to apply a rebound force to the sliding seat 41. A sliding push pin 41-1 that can move sequentially in the track groove 2-1 is arranged in the sliding seat 41. During the opening or closing process of the movable rail 82, the sliding push pin 41-1 can move in the track groove 2-1. At the same time, the sliding push pin 41-1 can be blocked and locked by the above-mentioned push pin limiting portion 21-2 and be released and rebound when the rebound trigger block 21 moves under the pressing action of the rebound push pin 82a. Generally speaking, the pressing action drives the movable rail 82 to move in the direction opposite to the rebound, driving the rebound trigger block 21 to move, so that the push pin limiting portion 21-2 releases the blockage of the rebound path in the track groove 2-1. At this time, under the action of the rebound spring 42, the sliding seat 41 can rebound. During the closing process of the movable rail 82, it is also necessary to drive the sliding seat 41 to return to the locked state to realize the stretching and energy storage of the rebound spring 42. For this purpose, a pushing mechanism is further arranged on the sliding seat 41. The pushing mechanism can be driven by the rebound push pin 82a to drive the sliding seat 41 to move in the direction of the above-mentioned push pin limiting portion 21-2 when the movable rail 82 closes, and at the same time, it is separated from the rebound push pin 82a when the sliding push pin 41-1 is blocked and locked by the above-mentioned push pin limiting portion 21-2, so as to stretch and store energy for the rebound spring 42 and lock the sliding seat 41.

[0061] The damping self-closing component 5 includes a self-closing spring seat 51, a damper 52, a self-closing chuck 54, and a self-closing spring 55. The self-closing spring seat 51 is slidably arranged on the base 2 and is connected to the above-mentioned sliding seat 41, so that the self-closing spring seat 51 can move together with the sliding seat 41; one end of the self-closing spring 55 is connected to the self-closing spring seat 51, and the other end is connected to the self-closing chuck 54. The damper 52 is installed on the base 2 and is connected to the self-closing chuck 54. The damper 52 can provide a damping effect opposite to the pulling force of the self-closing spring 55, so that the self-closing spring 55 can pull the self-closing chuck 54 to move slowly. The self-closing chuck 54 can be locked on the base 2 at a position away from the dial pin limiting part 21-2, and is unlocked and combined with the self-closing dial pin 82b when the movable rail 82 is closed, so as to drive the movable rail 82 to move and close in the opposite direction of the rebound direction under the combined action of the damper 52 and the self-closing spring 55; when the sliding seat 41 is unlocked and rebounds, the sliding seat 41 drives the self-closing chuck 54 and the movable rail 82 to rebound together through the self-closing spring seat 51. Since the self-closing spring seat 51 is connected to the sliding seat 41, after the sliding seat 41 is unlocked and rebounds, the sliding seat 41 drives the self-closing spring seat 51 to rebound together, and at this time the self-closing spring 55 is also in a stretched state, and can provide a rebound force at the same time, and the movable rail 82 is driven to rebound and open by the self-closing chuck 54; when the movable rail 82 is closed from the open state, the movable rail 82 first drives the sliding seat 41 to move in the opposite direction of the rebound, stretching and storing energy for the rebound spring 42 and the self-closing spring 55, and after the self-closing dial pin 82b collides and combines with the self-closing chuck 54, the self-closing spring 55 drives the self-closing chuck 54 and the movable rail 82 to be automatically pulled back together and move slowly under the action of the damper 52.

[0062] For the slide rail with the functions of pressing and rebounding and damping closing in this embodiment, the sliding seat 41 is responsible for stretching and storing energy of the rebound spring 42 and the self-closing spring 55 and unlocking and rebounding. The self-closing chuck 54 in the damping self-closing component 5 is responsible for the transmission of the rebound force and the self-closing pulling force, which simplifies the structure of the rebound component 4, reduces the manufacturing difficulty and cost, and further improves the structural compactness of the pressing and rebounding damping slide rail. Moreover, the rebound component 4 and the damping self-closing component 5 are designed on the same base 2, which improves the cooperation stability between the two.

[0063] Such as Figure 6As shown in the figure, in this embodiment, the above-mentioned pushing mechanism includes a swing arm 41-2, a telescopic block 41-3, and a compression spring 41-4. One end of the swing arm 41-2 is rotatably installed in the sliding seat 41. The sliding dial pin 41-1 is installed on the swing arm 41-2, so that the swing arm 41-2 makes a yaw movement as the position of the sliding dial pin 41-1 in the track groove 2-1 changes; the telescopic block 41-3 is movably arranged on one side of the swing arm 41-2, and the compression spring 41-4 is arranged between the telescopic block 41-3 and the swing arm 41-2, so that the telescopic block 41-3 maintains an elastic tendency to protrude outward from the swing arm 41-2. A notch for the telescopic block 41-3 to protrude is also provided on one side of the sliding seat 41. As Figure 10 shown, the above-mentioned track groove 2-1 includes a closed guide groove 2-1a, a rebound guide groove 2-1b, and a transition guide groove 2-1c. The dial pin limiting part 21-2 is located at the transition guide groove 2-1c and is used to block and lock or unlock and release the sliding dial pin 41-1 at the transition guide groove 2-1c. The closed guide groove 2-1a is arranged along the opening and closing direction of the moving member. When the sliding dial pin 41-1 is in the closed guide groove 2-1a, the telescopic block 41-3 protrudes outward with the swing arm 41-2 to be combined with the rebound dial pin 82a in the closing movement direction of the movable rail 82 and move therewith; when the sliding dial pin 41-1 is in the transition guide groove 2-1c and the rebound guide groove 2-1b, the telescopic block 41-3 swings inward with the swing arm 41-2 and disengages from the rebound dial pin 82a. Through the setting of the above-mentioned pushing mechanism, the interference of the telescopic block 41-3 on the damping closing and rebound opening of the movable rail 82 is avoided, and it has the advantages of simple and compact structure, convenient manufacturing and assembly, stable and reliable movement, etc.

[0064] Specifically, as Figure 6As shown, the sliding seat 41 in this embodiment includes a housing composed of a sliding box body 41-5 and a cover plate 41-6. A rotating shaft 41-5a is provided on the sliding box body 41-5, and a shaft hole 41-2a is provided on the swing arm 41-2. The swing arm 41-2 is rotatably mounted on the rotating shaft 41-5a through the shaft hole 41-2a. The sliding dial pin 41-1 is fixed at one end far from the rotating shaft 41-5a. An arc-shaped hole for the sliding dial pin 41-1 to pass through is also provided at the bottom of the sliding box body 41-5. The cover plate 41-6 is fixed on the sliding box body 41-5 by screws, so that the whole swing arm 41-2 is located inside the sliding box body 41-5. An expansion hole 41-2b is also provided on one side of the swing arm 41-2. The tail end of the expansion block 41-3 is arranged in the expansion hole 41-2b. A limiting convex block is also provided on the side wall of the expansion block 41-3, so that the expansion block 41-3 can be stably limited on the swing arm 41-2 and can flexibly expand and contract. In addition, the protruding end of the expansion block 41-3 has an avoidance inclined surface 41-3a arranged in the rebound direction towards the movable rail 82. When the movable rail 82 rebounds and opens, the rebound dial pin 82a cooperates with the avoidance inclined surface 41-3a to press the expansion block 41-3 to contract inward, so that the rebound dial pin 82a can cross the expansion block 41-3, ensuring the reliability and smoothness of the rebound.

[0065] Further referring to Figure 10 As shown, in this embodiment, the closing guide groove 2-1a and the transition guide groove 2-1c are connected by a guiding arc. When the rebound dial pin 82a pushes the expansion block 41-3 to move along the closing movement direction of the movable rail 82, the sliding dial pin 41-1 is guided by the guiding arc and enters the transition guide groove 2-1c, and drives the expansion block 41-3 to generate an inward deflection and tilt, so that the rebound dial pin 82a presses the expansion block 41-3 to contract and cross the expansion block 41-3. Specifically, when the sliding dial pin 41-1 is located in the closing guide groove 2-1a, the pushing force direction of the rebound dial pin 82a on the expansion block 41-3 is basically perpendicular to the expansion and contraction direction of the expansion block 41-3. Therefore, at this time, the rebound dial pin 82a does not generate a pushing force in the contraction direction on the expansion block 41-3. When the sliding dial pin 41-1 passes through the guiding arc, the whole swing arm 41-2 swings, and then the contact surface between the expansion block 41-3 and the rebound dial pin 82a tilts. At this time, the rebound dial pin 82a will generate a component force in the contraction direction on the expansion block 41-3, and then press the expansion block 41-3 to contract and separate from the rebound dial pin 82a. The above guiding arc design, on the one hand, enables the sliding dial pin 41-1 to smoothly and stably enter the transition guide groove 2-1c from the closing guide groove 2-1a, and on the other hand, can realize the separation of the rebound dial pin 82a and the expansion block 41-3 through the deflection of the swing arm 41-2, ensuring the stability and reliability of the functions of the slide rail pressing rebound and damping closing.

[0066] As Figure 10As shown in the figure, in this embodiment, a first return spring 21-4 is provided between the rebound trigger block 21 and the base 2 to enable the needle-pushing limiting portion 21-2 to have an elastic tendency to stay in the transition guide groove 2-1c, ensuring the stability of the reset action of the rebound trigger block 21. One end of the rebound guide groove 2-1b away from the transition guide groove 2-1c further has a reset channel 2-1d for guiding the sliding needle-pushing member 41-1 into the closed guide groove 2-1a for reset. To improve the reliability of the movement of the sliding needle-pushing member 41-1 in the track groove 2-1, in this embodiment, a blocking block 22 is also movably provided on the base 2. One end of the blocking block 22 has a guiding inclined surface 22-1 located in the rebound guide groove 2-1b. When the blocking block 22 moves in the rebound direction, the guiding inclined surface 22-1 forms a reset channel 2-1d connecting the rebound guide groove 2-1b and the closed guide groove 2-1a, and vice versa, the reset channel 2-1d is closed; a second return spring 22-2 is also provided between the blocking block 22 and the base 2 to enable the blocking block 22 to maintain an elastic tendency to close the reset channel 2-1d. This blocking block 22 closes the reset channel 2-1d between the rebound guide groove 2-1b and the closed guide groove 2-1a during the closing process of the movable rail 82, ensuring that the sliding needle-pushing member 41-1 can move stably and sequentially in the track groove 2-1, preventing the sliding needle-pushing member 41-1 from mistakenly entering the closed guide groove 2-1a and causing the premature separation of the movable rail 82 and the telescopic block 41-3. At the same time, during the rebound opening process of the movable rail 82, the sliding needle-pushing member 41-1 can be used to push the blocking block 22 away for reset; in addition, a second return spring 22-2 is also provided between the blocking block 22 and the base 2 to enable the blocking block 22 to maintain an elastic tendency to close the reset channel 2-1d. During the rebound opening process, the blocking block 22 can play a certain buffering role on the sliding needle-pushing member 41-1, effectively preventing the collision and abnormal noise between the sliding seat 41 and the base 2. Further referring to Figure 10 As shown, the end of the needle-pushing limiting portion 21-2 is in a concave arc shape, and this concave arc shape is used to guide the sliding needle-pushing member 41-1 from the transition guide groove 2-1c to the rebound guide groove 2-1b; when the needle-pushing limiting portion 21-2 extends into the transition guide groove 2-1c, the sliding needle-pushing member 41-1 is blocked and locked by the reduction of the size of the transition guide groove 2-1c. With the above design of the needle-pushing limiting portion 21-2, it can not only guide the sliding needle-pushing member 41-1, but also block and lock the sliding needle-pushing member 41-1. The structural design is simple, and the guiding and locking of the sliding needle-pushing member 41-1 are stable and reliable.

[0067] As Figure 4 、 Figure 5 and Figure 7As shown, in this embodiment, a rotating wheel 44 is further provided on the base 2. The rebound tension spring 42 bypasses the rotating wheel 44, and the rebound tension spring 42 is connected to the base 2 through a rebound adjustment block 43. There are at least two rebound force adjustment grooves on the base 2 that can be engaged with the rebound adjustment block 43. By adjusting the connection between the rebound adjustment block 43 and different rebound force adjustment grooves, the pre-tension of the rebound tension spring 42 is adjusted, thereby realizing the adjustment of the magnitude of the rebound force. The rotating wheel 44 is rotatably installed on the mounting shaft 2-2 of the base 2. By bypassing the rotating wheel 44 with the rebound tension spring 42, the length of the rebound tension spring 42 can be longer without increasing the length dimension of the base 2, improving the structural compactness.

[0068] Referring to Figures 3 to 5 and Figures 7 to 10 As shown, the above-mentioned rebound damping device further includes a synchronization component 6. The synchronization component 6 includes a synchronization gear 61, a connecting piece 62, and a synchronization transmission rod 63. The synchronization gear 61 is rotatably installed on the base 2. The rebound trigger block 21 has a rack 21-3 that meshes with the synchronization gear 61. The synchronization gear 61 is coaxially connected to the synchronization transmission rod 63 through the connecting piece 62; when the rebound trigger block 21 moves under the pressing action of the rebound dial pin 82a, the synchronization transmission rod 63 is driven to rotate through the meshing transmission of the rack 21-3 and the synchronization gear 61. Using the pressing trigger movement of the rebound trigger block 21 to drive the rotation of the synchronization transmission rod 63, the structure is simple, the transmission is stable, and the synchronous pressing and rebound actions of the two groups of slide rails can be realized.

[0069] Connect Figure 4 , Figure 5 and Figures 7 to 9 As shown, in this embodiment, the above-mentioned rebound component 4 and the damping self-closing component 5 are respectively arranged on opposite surfaces of the base 2, further improving the structural compactness of the rebound damping device, reducing its overall size, and improving the installation applicability of the rebound damping device. The damper 52 is installed in the damper installation groove 2-5 of the base 2. The self-closing spring seat 51 is slidably arranged in the spring seat sliding groove 2-6 of the base 2. The self-closing spring seat 51 is provided with a boss 51a. The boss 51a passes through the base 2 and is connected to the jack 41-5b on the sliding seat 41 to realize the synchronous movement of the sliding seat 41 and the self-closing spring seat 51; the self-closing chuck 54 is connected to the damper 52 and the self-closing spring 55 through the self-closing slider 53. The self-closing chuck 54 is rotatably installed on the self-closing slider 53. The base 2 has a guide rib 2-4 that slidably cooperates with the self-closing chuck 54. One end of the guide rib 2-4 away from the dial pin limiting portion 21-2 has a corner 2-4a. The self-closing chuck 54 has an arc groove that cooperates with the corner 2-4a. When the self-closing chuck 54 is pulled by the self-closing dial pin 82b and moves towards the corner 2-4a, the self-closing chuck 54 rotates along the corner 2-4a under the action of an eccentric tensile force and engages with the corner 2-4a and separates from the self-closing dial pin 82b. At this time, the movable rail 82 can continue to be pulled open.

[0070] like Figure 4 and Figure 5 As shown, in this embodiment, the base 2 is slidably mounted on the base 1, and the base 1 is used to connect with the fixed rail 81. There is also an adjuster 7 between the base 2 and the base 1 for adjusting the relative position of the base 2 on the base 1. Similar to the prior art, the adjuster 7 adopts a dial structure, one side of which has a spiral groove and the other side has a graduated positioning groove. The adjuster 7 is rotatably mounted on the base 2. The base 2 has an adjustment protrusion 2-3 that matches the spiral groove, and the base 1 has a positioning convex point that matches the graduated positioning groove. By turning the adjuster 7, the front and rear positions between the base 2 and the base 1 can be adjusted to achieve the adjustment of the pressing gap. The upper part of the base 2 is also provided with an upper cover 3, which is fixed to the base 2 by screws, so that the entire rebound component 4 is confined in the base 2. The damping self-closing component 5 is located on the back of the base 2 and is confined in the base 2 by the base 1.

[0071] Reference Figure 11As shown in the figure, for the slide rail with the functions of pressing and rebounding and damping closing in this embodiment, a switching pin 9 for locking or unlocking the rebound trigger block 21 is further provided on one side of the base 2 close to the rebound trigger block 21. When the switching pin 9 locks the rebound trigger block 21, the dial pin limiting part 21-2 remains in the track groove 2-1 and cannot be pressed and rebounded; when the switching pin 9 unlocks the rebound trigger block 21, the rebound trigger block 21 can be normally pressed to achieve unlocking and rebounding. The switching pin 9 can be used to prevent the slide rail from being accidentally triggered to rebound and pop out, such as popping out under non-subjective pressing conditions such as handling, transportation, and accidental collision; when the pressing function is restricted by the switching pin, the slide rail can be pulled out and can also be normally closed, so it can be used as a normal damping slide rail; that is to say, this slide rail has both a rebound function and a damping self-closing function, can meet two usage scenarios, and can be freely switched. Specifically, a locking groove 21-5 is provided on the rebound trigger block 21. The switching pin 9 is detachably installed on the side wall of the base 2, and the switching pin 9 has a pin head 9-1 corresponding to the position of the above-mentioned locking groove 21-5. A positioning structure is also provided between the switching pin 9 and the base 2. The positioning structure can include a positioning protrusion 2-7 provided on the base 2 and a positioning groove 9-2 provided on the side wall of the switching pin 9. Two positioning grooves 9-2 can be provided. When the rebound trigger block 21 is locked, the switching pin 9 is pressed inward, so that the pin head 9-1 is inserted into the locking groove 21-5. At this time, the rebound trigger block 21 is locked and cannot be pressed, thereby restricting the pressing and rebounding function; when the switching pin 9 is pulled outwards, at this time the pin head 9-1 releases the locking of the locking groove 21-5, and at this time the rebound trigger block 21 can be normally pressed to unlock and achieve the rebound function. The two positioning grooves 9-2 just correspond to the locking and unlocking positions of the switching pin 9 for the rebound trigger block 21, ensuring the position stability of the switching pin 9. As Figure 11 shown, the above-mentioned switching pin 9 is limited and installed on the base 2 through a pressing block 23. At the same time, the above-mentioned synchronous gear 61 can also be limited through the pressing block 23, so that the synchronous gear 61 can rotate stably on the base 2.

[0072] To further understand the technical content of the slide rail with the functions of pressing and rebounding and damping closing of the present invention, now in combination with FIGS. 12(a) to 12(e) and Figures 13(a) to 13(e) the working principle of the present invention is further elaborated.

[0073] Pressing and rebounding process: Figures 12(a) to 12(e) The pressing and rebounding process of the slide rail with the functions of pressing and rebounding and damping closing of the present invention is shown.

[0074] As shown in Fig. 12(a), when the movable rail 82 is in the closed state, at this time, the self-closing tension spring 55 has a pulling force on the self-closing chuck 54, and the self-closing dial pin 82b is combined with the self-closing chuck 54, so the movable rail 82 is restricted in the closed state. In this state, the dial pin limiting part 21-2 of the rebound trigger block 21 extends into the transition guide groove 2-1c, so that the sliding dial pin 41-1 is restricted in the transition guide groove 2-1c. At this time, both the rebound tension spring 42 and the self-closing tension spring 55 are in the stretched state.

[0075] As shown in Fig. 12(b), when it is necessary to open the movable rail 82, by applying a pressing action to the drawer panel, the movable rail 82 moves inward, and the rebound dial pin 82a is used to push the trigger part 21-1, so that the whole rebound trigger block 21 moves in the opposite direction of the rebound. The dial pin limiting part 21-2 loses its limiting effect on the sliding dial pin 41-1. At this time, the sliding dial pin 41-1 can enter the rebound guide groove 2-1b from the transition guide groove 2-1c. Under the action of the rebound tension spring 42 and the self-closing tension spring 55, the sliding seat 41 and the self-closing tension spring seat 51 rebound and move together, and the self-closing chuck 54 is used to drive the movable rail 82 to bounce open. During this process, the movement of the rebound trigger block 21 is converted into the rotational movement of the synchronous transmission rod 63 through the gear-rack mechanism. The synchronous transmission rod 63 can drive the corresponding rebound trigger block 21 in the other set of slide rails to move, realizing the synchronous unlocking and rebound of the two sets of slide rails.

[0076] As shown in Fig. 12(c), when the sliding dial pin 41-1 contacts the blocking block 22, since the rebound pulling force is greater than the elastic force of the second return spring 22-2 of the blocking block 22, the sliding dial pin 41-1 can push the blocking block 22 away and return to the closing guide groove 2-1a through the return channel 2-1d.

[0077] At this time, the drawer panel has been ejected a certain distance, and the user can pull the drawer panel further outward to open the drawer. During this process, as shown in Fig. 12(d), when the self-closing dial pin 82b drives the self-closing chuck 54 to continue moving to the corner 2-4a position, the self-closing chuck 54 rotates along the corner 2-4a under the action of the eccentric pulling force and is buckled with the corner 2-4a and separated from the self-closing dial pin 82b.

[0078] As shown in Fig. 12(e), continue to pull the drawer panel. At this time, the rebound dial pin 82a passes through the telescopic block 41-3. The rebound dial pin 82a contracts the telescopic block 41-3 inward along its avoiding inclined plane 41-3a, so as to cross the telescopic block 41-3 and realize the complete opening of the drawer panel or the movable rail 82.

[0079] Closing process of the slide rail: Figures 13(a) to 13(e) The closing process of the pressing rebound damping device is shown.

[0080] As shown in Figure 13(a), when the movable rail 82 is in the fully open state, the self-closing clamp 54 is at the corner 2-4a position and is stuck. At the same time, since the sliding pin 41-1 is located in the closed guide groove 2-1a, the swing arm 41-2 and the telescopic block 41-3 are in an outward swinging state, so that the telescopic block 41-3 can block the rebounding pin 82a.

[0081] As shown in Figure 13(b), when the drawer is closed, the movable rail 82 moves in the closing direction. At this time, the rebound pin 82a first contacts the telescopic block 41-3 and pushes the telescopic block 41-3 to move together, thereby driving the sliding seat 41 and the self-closing spring seat 51 to move together, stretching the rebound spring 42 and the self-closing spring 55 to store energy, and stretching the damper 52 to the open state.

[0082] As shown in Figure 13(c), when the sliding pin 41-1 moves to the transition guide groove 2-1c position, under the action of the guide arc between the closing guide groove 2-1a and the transition guide groove 2-1c, the sliding pin 41-1 enters the transition guide groove 2-1c and is blocked and limited by the pin limiter 21-2, completing the stretching energy storage of the rebound tension spring 42 and the self-closing tension spring 55.

[0083] At the same time, as shown in FIG. 13( d ), when the sliding pin 41 - 1 enters the transition guide groove 2 - 1 c, the swing arm 41 - 2 and the telescopic block 41 - 3 are deflected. At this time, since the contact surface between the rebound pin 82 a and the telescopic block 41 - 3 is inclined, a compressive force component is generated on the telescopic block 41 - 3, causing the telescopic block 41 - 3 to shrink inward, thereby causing the rebound pin 82 a to continue to move forward over the telescopic block 41 - 3. At the same time, the self-closing pin 82 b collides with the self-closing clamp 54, causing it to separate from the corner 2 - 4 a, and rotate to a position engaged with the self-closing pin 82 b. At this time, under the action of the self-closing tension spring 55 and the damper 52, the movable rail 82 can be slowly pulled closed. That is to say, when closing the drawer, it is only necessary to push the drawer, and under the action of inertia, the self-closing pin 82 b of the movable rail 82 collides with the self-closing clamp 54, so that the drawer can be slowly and automatically closed.

[0084] As shown in FIG. 13( e ), when the movable rail 82 is completely closed, the rebound needle 82 a moves to the trigger portion 21 - 1 again to facilitate the next press to bounce open.

[0085] During handling or transportation, in order to prevent the drawer from accidentally opening, the switch latch 9 can be pressed inward, and the latch head 9-1 can be used to lock the rebound trigger block 21. At this time, the rebound trigger block 21 cannot be pressed to unlock, which effectively prevents the drawer from accidentally opening; but at this time, the slide rail can still be pulled open normally and closed with damping, and can be used as a normal damping closing slide rail. According to different rebound requirements, the rebound force can be adjusted by changing the position of the rebound adjustment block 43.

[0086] The slide rail with the functions of pressing and rebounding and damping closing of the present invention integrates a rebounding component and a damping self-closing component on the same base, and respectively cooperates with a rebounding pin and a self-closing pin on the movable rail. By using the structural cooperation of the rebounding component and the damping self-closing component, it is realized that during the rebounding and damping self-closing processes of the slide rail, the force transmission can be achieved through the self-closing chuck of the damping self-closing component, so that the rebounding component only needs to be responsible for rebounding triggering and closing energy storage. Furthermore, the structure of the rebounding component is simplified, the manufacturing difficulty and cost are reduced, and the structural compactness of the pressing and rebounding damping slide rail is further improved.

[0087] The present invention and its embodiments are schematically described above. The description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative work without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
