Description

Technical Field

[0001] The present invention relates to the technical field of drawers, and particularly to a drawer slide rail assembly with synchronous sliding opening and closing by pressing. Background Art

[0002] Chinese Patent Document No. CN111642918B discloses a labor-saving and silent pressing and rebounding opening and closing device for furniture on February 7, 2025, which includes a rebounding bracket, a pushing element, and a pressing element. The rebounding bracket is provided with a loop groove, the pushing element is provided with a sliding shaft portion, and the pressing element elastically expands and contracts and is limited to slide on the pushing element and / or the rebounding bracket, and when sliding, acts on and drives the sliding shaft portion to be positioned and / or slide along the trajectory of the loop groove in a sequential direction. It also includes a lever assembly, the lever assembly is provided with a lever acting portion, the pushing element is provided with a pushing acting portion, and the loop groove is at least provided with an upper limit sliding area, a conversion area, and a front stay area; when the sliding shaft portion slides on the upper limit sliding area, it acts on and drives the pressing element and the pushing element to slide out of the rebounding bracket, when the sliding shaft portion slides on the upper limit sliding area to a certain position and is separated from the pressing element, the pushing element interacts with the lever acting portion through the pushing acting portion when the sliding shaft portion and the pressing element are separated. This pressing and rebounding opening and closing device is applied to a drawer, and the pressing and rebounding opening and closing device is arranged between the moving rail and the fixed rail. After the drawer is closed, when the drawer panel is pressed, the drawer will pop out through the pressing and rebounding opening and closing device. There are two moving rails and fixed rails, so there are also two pressing and rebounding opening and closing devices. However, there is no synchronization device between the two pressing and rebounding opening and closing devices. When the left or right side of the drawer panel is pressed (that is, when the user does not press at the middle position of the drawer panel), the two pressing and rebounding opening and closing devices cannot move synchronously, resulting in the drawer popping out obliquely, so that the drawer cannot be fully opened on the cabinet body, and the user needs to pull out the drawer by himself to fully open the drawer.

[0003] Therefore, it is necessary to make further improvements. Summary of the Invention

[0004] The purpose of the present invention is to provide a drawer slide rail assembly with synchronous sliding opening and closing by pressing, which has a simple structure, high synchronization, convenient use, good user experience, and strong practicability, so as to overcome the deficiencies of the prior art.

[0005] A drawer slide rail assembly with synchronous sliding opening and closing by pressing designed according to this purpose includes a moving rail and a fixed rail, and a pressing and rebounding opening and closing mechanism is arranged between the moving rail and the fixed rail. It is characterized in that: the pressing and rebounding opening and closing mechanism includes a rebounding bracket, a pushing element, a pressing element, and a transmission member for connecting a synchronization device. The rebounding bracket is fixed on the fixed rail, the pushing element and the transmission member elastically slide on the rebounding bracket, and the pressing element elastically expands and contracts and is limited to slide on the pushing element and / or the rebounding bracket; When the pressing and rebounding opening and closing mechanism is in a pending state, the pushing element is locked on the rebounding bracket; When the pressing and rebounding opening and closing mechanism is unlocked, the pressing element drives the pushing element to be unlocked on the rebounding bracket. The pushing element moves under the action of the released elastic force and drives the transmission part and the synchronization device to move. When the pushing element and the transmission part move to corresponding positions, they are separated from each other, and the pushing element acts on and drives the pressing element to extend outside the rebounding bracket. The pressing element pushes the moving rail to slide and open on the fixed rail.

[0006] A first elastic element is arranged between the pushing element and the rebounding bracket. One end of the first elastic element is elastically connected to the pushing element, and the other end is elastically connected to the rebounding bracket. A second elastic element is arranged between the transmission part and the rebounding bracket. One end of the second elastic element is elastically connected to the transmission part, and the other end is elastically connected to the rebounding bracket. When the pressing and rebounding opening and closing mechanism is unlocked, the elastic acting force of the first elastic element is greater than the elastic acting force of the second elastic element.

[0007] A track groove is arranged on the rebounding bracket. An upper limit sliding area and a lower limit sliding area are arranged on the track groove. A sliding shaft part is arranged on the pushing element; When the pressing element elastically stretches and limits and slides on the pushing element and / or the rebounding bracket, it acts on and drives the sliding shaft part to slide on the lower limit sliding area; An unlocking sliding area is arranged on the transmission part. When the pressing element drives the pushing element to be unlocked on the rebounding bracket, the sliding shaft part slides into the unlocking sliding area and pushes the transmission part and the synchronization device to move. When the pushing element and the transmission part move to corresponding positions, they are separated from each other, and the sliding shaft part slides from the unlocking sliding area to the upper limit sliding area. When the sliding shaft part slides on the upper limit sliding area, it drives the pressing element to extend outside the rebounding bracket.

[0008] A matching part moving on the track groove is arranged on the transmission part. When the pressing and rebounding opening and closing mechanism is in a pending state, a locking position is formed between the matching part and the track groove, and the sliding shaft part is positioned at the locking position; When the pressing and rebounding opening and closing mechanism is unlocked, the pressing element drives the pushing element to slide from the locking position into the unlocking sliding area; When the pushing element and the transmission part move to corresponding positions, the sliding shaft part and the matching part are separated from each other, and the transmission part resets under the elastic force of the second elastic element.

[0009] It further includes a lever assembly. The lever assembly is respectively cooperatively connected with the rebounding bracket and the pressing element. A lever acting part is arranged on the lever assembly. A pushing acting part is arranged on the pushing element. A conversion area and a front staying area are further arranged on the track groove; When the sliding shaft part slides to a corresponding position on the upper limit sliding area, it disengages from the pressing element. When the sliding shaft part and the pressing element disengage, the pushing element interacts with the lever acting part through the pushing acting part. The lever assembly moves on the rebound bracket under the action of the pushing element and drives the pressing element to continue to slide out of the rebound bracket. When the pushing element slides on the rebound bracket, it drives the sliding shaft part to buffer-slide from the upper limit sliding area to the conversion area and stay in the front stay area. When the sliding shaft part stays in the front stay area, the pressing element extends out and is positioned outside the rebound bracket.

[0010] There is a movable part arranged on the moving rail, and a rear area sliding-in guiding part is arranged on the pressing element; when the moving rail slides and closes on the fixed rail, it drives the pressing element and the movable part to move towards the transmission part. When the movable part moves towards the transmission part, it drives the lever assembly to rotate on the rebound bracket, and the lever acting part interacts with the pushing acting part to drive the pushing element to move towards the transmission part. The sliding shaft part slides from the front stay area to the lower limit sliding area. When the sliding shaft part slides to a corresponding position on the lower limit sliding area, it interacts with the rear area sliding-in guiding part and drives the pushing element to continue to move towards the transmission part. The pushing acting part disengages from the lever acting part when the sliding shaft part and the rear area sliding-in guiding part act.

[0011] When the pressing element moves towards the transmission part, it slides into the rebound bracket, and the pressing element acts through the rear area sliding-in guiding part and drives the sliding shaft part to be inclined and guided to slide from the lower limit sliding area and be positioned in the locking position. When the sliding shaft part is positioned in the locking position, it disengages from the rear area sliding-in guiding part. When the sliding shaft part is positioned in the locking position, the pressing element extends into and is positioned inside the rebound bracket. There is also a rear area sliding-out guiding part arranged on the pressing element; the pressing element interacts with or disengages from the sliding shaft part through the rear area sliding-out guiding part. When the sliding shaft part is positioned in the locking position and the pressing element presses and slides relative to the rebound bracket, the pressing element acts through the rear area sliding-out guiding part and drives the sliding shaft part to slide out obliquely from the locking position to the unlocking sliding area. There is also a pressing acting part arranged on the pressing element. When the sliding shaft part slides on the upper limit sliding area, it acts on the pressing acting part to drive the pressing element to slide out of the rebound bracket. When the sliding shaft part slides to a corresponding position on the upper limit sliding area, it disengages from the pressing acting part.

[0012] A limiting part is arranged on the pressing element, and a limiting matching part is arranged on the pushing element. There is also a third elastic part arranged between the pressing element and the pushing element. One end of the third elastic part is elastically connected to the pressing element, and the other end is elastically connected to the pushing element; the pressing element is always elastically telescoped and limited and slides on the limiting matching part of the pushing element towards the locking position through the cooperation of the limiting part and the third elastic part; the elastic acting force of the first elastic part is greater than the elastic acting force of the third elastic part.

[0013] The synchronization device includes a synchronization rod that is cooperatively connected to a transmission member. A drawer is provided on the moving rail, and the drawer is supported on two moving rails. The pressing and rebounding opening and closing mechanisms on each moving rail are cooperatively connected through the synchronization rod. When one of the pressing and rebounding opening and closing mechanisms is unlocked, the pushing elements, pressing elements, and transmission members of the two pressing and rebounding opening and closing mechanisms move synchronously through the synchronization rod, so that the two moving rails of the drawer slide open elastically and synchronously on the fixed rail.

[0014] A first engaging portion is provided on the transmission member, and a second engaging portion is provided on the synchronization rod. The transmission member and the synchronization rod are connected through the cooperation of the first engaging portion and the second engaging portion.

[0015] In the drawer slide rail assembly of the present invention, by providing a transmission member on the pressing and rebounding opening and closing mechanism, the transmission members of the two pressing and rebounding opening and closing mechanisms are connected through a synchronization device. When the user presses at any position on the drawer panel, the pushing elements, pressing elements, and transmission members of the two pressing and rebounding opening and closing mechanisms move synchronously through the synchronization rod, so that the two moving rails of the drawer can slide open elastically and synchronously on the fixed rail, preventing the drawer from tilting out and causing the drawer not to be fully opened on the cabinet body. Therefore, it is not necessary for the user to pull out the drawer by himself, greatly improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Referring to Figures 1 - 9 , the drawer slide rail assembly with pressing synchronization sliding opening and closing of the present invention includes a moving rail 1 and a fixed rail 2. A pressing and rebounding opening and closing mechanism 3 is provided between the moving rail 1 and the fixed rail 2. The pressing and rebounding opening and closing mechanism 3 includes a rebounding bracket 4, a pushing element 5, a pressing element 6, and a transmission member 7 for connecting a synchronization device 8. The rebounding bracket 4 is fixed on the fixed rail 2. The pushing element 5 and the transmission member 7 slide elastically on the rebounding bracket 1. The pressing element 6 slides elastically and telescopically and is limited on the pushing element 5 and / or the rebounding bracket 1; When the pressing and rebounding opening and closing mechanism 3 is in a pending state, the pushing element 5 is locked on the rebounding bracket 4, and at this time the drawer is in a closed state; When the pressing and rebounding opening and closing mechanism 3 is unlocked, the pressing element 6 drives the pushing element 5 to be unlocked on the rebounding bracket 4. The pushing element 5 moves under the action of the released elastic force and drives the transmission member 7 and the synchronization device 8 to move. When the pushing element 5 and the transmission member 7 move to corresponding positions, they are separated from each other, and the pushing element 5 acts on and drives the pressing element 6 to extend out of the rebounding bracket 1, and the pressing element 6 pushes the moving rail 1 to slide and open on the fixed rail 2.

[0022] A first elastic member 13 is arranged between the pushing element 5 and the rebounding bracket 4. The first elastic member 13 is a tension spring. One end of the first elastic member 13 is elastically connected to the pushing element 5, and the other end is elastically connected to the rebounding bracket 4. A second elastic member 14 is arranged between the transmission member 7 and the rebounding bracket 4. The second elastic member 14 is a tension spring. One end of the second elastic member 14 is elastically connected to the transmission member 7, and the other end is elastically connected to the rebounding bracket 4. When the pressing and rebounding opening and closing mechanism 3 is unlocked, the elastic acting force of the first elastic member 13 is greater than the elastic acting force of the second elastic member 14. When the pressing element 6 drives the pushing element 5 to be unlocked on the rebounding bracket 4, the pushing element 5 moves under the elastic force of the first elastic member 13 and drives the transmission member 7 and the synchronization device 8 to move.

[0023] A track groove 9 is arranged on the rebounding bracket 4. An upper limit sliding area 11 and a lower limit sliding area 12 are arranged on the track groove 9. A sliding shaft portion 10 is arranged on the pushing element 5; When the pressing element 6 elastically expands and contracts and is limited and slides on the pushing element 5 and / or the rebounding bracket 1, it acts on and drives the sliding shaft portion 10 to slide on the lower limit sliding area 12; An unlocking sliding area 32 is arranged on the transmission member 7. When the pressing element 6 drives the pushing element 5 to be unlocked on the rebounding bracket 4, the sliding shaft portion 10 slides into the unlocking sliding area 32 and pushes the transmission member 7 and the synchronization device 8 to move. When the pushing element 5 and the transmission member 7 move to corresponding positions, they are separated from each other, and the sliding shaft portion 10 slides from the unlocking sliding area 32 to the upper limit sliding area 11. When the sliding shaft portion 10 slides on the upper limit sliding area 11, it drives the pressing element 6 to extend out of the rebounding bracket 1.

[0024] A matching portion 15 moving on the track groove 9 is arranged on the transmission member 7. When the pressing and rebounding opening and closing mechanism 3 is in a pending state, a locking position 16 is formed between the matching portion 15 and the track groove 9, and the sliding shaft portion 10 is positioned at the locking position 16, so that the pushing element 5 is locked on the rebounding bracket 4; When the pressing and rebounding opening and closing mechanism 3 is unlocked, the pressing element 6 drives the pushing element 5 to slide from the locking position 16 into the unlocking sliding area 32, and the sliding shaft portion 10 pushes the transmission member 7 and the synchronization device 8 to move through the matching portion 15; When the pushing element 5 and the transmission member 7 move to their corresponding positions, the sliding shaft portion 10 and the mating portion 15 are separated from each other, and the transmission member 7 is reset under the elastic force of the second elastic member 14.

[0025] It further includes a lever assembly 29. The lever assembly 29 is respectively connected to the rebound bracket 4 and the pressing element 6 in a cooperative manner. A lever action portion 17 is provided on the lever assembly 29, a pushing action portion 18 is provided on the pushing element 5, and a conversion area 19 and a front stop area 20 are further provided on the track groove 9. When the sliding shaft portion 10 slides to a corresponding position on the upper limit sliding area 11, it is separated from the pressing element 6. When the sliding shaft portion 10 and the pressing element 6 are separated, the pushing element 5 interacts with the lever action portion 17 through the pushing action portion 18. The lever assembly 29 moves on the rebound bracket 4 under the action of the pushing element 5 and drives the pressing element 6 to continue sliding out of the rebound bracket 4. When the pushing element 5 slides on the rebound bracket 4, it drives the sliding shaft portion 10 to buffer-slide from the upper limit sliding area 11 to the conversion area 19 and stay within the front stop area 20. When the sliding shaft portion 10 stays within the front stop area 20, the pressing element 6 extends and is positioned outside the rebound bracket 4. Before the sliding shaft portion 10 enters the conversion area 19, it is separated from the pressing element 6, and only through the cooperation between the lever action portion 17 and the pushing action portion 18 can the pushing element 5 and the pressing element 6 extend and be positioned outside the rebound bracket 4. Therefore, the collision and abnormal noise generated when the sliding shaft portion 10 stays in the front stop area 20 can be reduced, and the sliding shaft portion 10 can slide into and stay in the front stop area 20 without collision, abnormal noise, and silently, thereby avoiding problems such as loose assembly between components due to inaccurate production dimensions and assembly positions of the rebound bracket 4, the pushing element 5, and the pressing element 6, and collision and abnormal noise when the sliding shaft portion 10 slides into and stays in the front stop area 20, thereby improving the connection compactness between components and the service life of the product. At the same time, the unnecessary contact between the sliding shaft portion 10 and the pressing element 6 can also be reduced, improving the service life of the product.

[0026] A movable member 21 is provided on the movable rail 1, and a rear area sliding-in guiding portion 22 is provided on the pressing element 6. When the movable rail 1 slides and closes on the fixed rail 2, it drives the pressing element 6 and the movable member 21 to move in the direction of the transmission member 7. When the movable member 21 moves in the direction of the transmission member 7, it drives the lever assembly 29 to rotate on the rebound bracket 4, and the lever action portion 17 interacts with the pushing action portion 18 to drive the pushing element 5 to move in the direction of the transmission member 7. The sliding shaft portion 10 slides from the front stop area 20 to the lower limit sliding area 12. When the sliding shaft portion 10 slides to a corresponding position on the lower limit sliding area 12, it interacts with the rear area sliding-in guiding portion 22 and drives the pushing element 5 to continue moving in the direction of the transmission member 7. When the sliding shaft portion 10 and the rear area sliding-in guiding portion 22 act, the pushing action portion 18 is separated from the lever action portion 17.

[0027] The lever assembly 29 includes a first lever 33 and a second lever 34. One end of the first lever 33 is rotatably arranged on the rebound bracket 4. When the moving part 21 moves towards the transmission part 7, the other end of the first lever 33 is pushed, so that the lever assembly 29 rotates on the rebound bracket 4. When the lever assembly 29 rotates to the corresponding position, the moving part 21 passes over the other end of the first lever 33, and the rear area slides into the guiding part 22 and acts on the sliding shaft part 10. One end of the second lever 34 is rotatably arranged on the first lever 33, and the other end is rotatably arranged on the pressing element 6. When the moving part 21 moves in the opposite direction of the transmission part 7, it clears and disengages from the first lever 33.

[0028] When the pressing element 6 moves towards the transmission part 7, it slides into the rebound bracket 4, and the pressing element 6 acts on and drives the sliding shaft part 10 to slide obliquely and be positioned at the locking position 16 from the lower limit sliding area 12 through the rear area sliding into the guiding part 22. When the sliding shaft part 10 is positioned within the locking position 16, it disengages from the rear area sliding into the guiding part 22. When the sliding shaft part 10 is positioned within the locking position 16, the pressing element 6 extends into and is positioned within the rebound bracket 4. The pressing element 6 is also provided with a rear area sliding out guiding part 23. The pressing element 6 interacts with or disengages from the sliding shaft part 10 through the rear area sliding out guiding part 23. When the sliding shaft part 10 is positioned within the locking position 16 and the pressing element 6 presses and slides relative to the rebound bracket 4, the pressing element 6 acts on and drives the sliding shaft part 10 to slide out obliquely from the locking position 16 to the unlocking sliding area 32 through the rear area sliding out guiding part 23. The pressing element 6 is also provided with a pressing acting part 24. When the sliding shaft part 10 slides in the upper limit sliding area 11, it acts on the pressing acting part 24 to drive the pressing element 6 to slide out of the rebound bracket 1. When the sliding shaft part 10 slides to the corresponding position in the upper limit sliding area 11, it disengages from the pressing acting part 24.

[0029] The pressing element 6 is provided with a limiting part 25, and the pushing element 5 is provided with a limiting cooperation part 26. A third elastic element 27 is also arranged between the pressing element 6 and the pushing element 5. The third elastic element 27 is a tension spring. One end of the third elastic element 27 is elastically connected to the pressing element 6, and the other end is elastically connected to the pushing element 5. The pressing element 6 is always elastically telescoped and limitedly slides on the limiting cooperation part 26 of the pushing element 5 towards the locking position 16 through the cooperation of the limiting part 25 and the third elastic element 27. The elastic acting force of the first elastic element 13 is greater than the elastic acting force of the third elastic element 27.

[0030] A pressing connection assembly is provided on the movable rail 1, and the pressing connection assembly includes a connecting piece 35 and an elastic pressing component 36. The connecting piece 35 is fixed on the movable rail 1, and the elastic pressing component 36 is installed on the connecting piece 35. When the elastic pressing component 36 is pressed, the pressing element 6 is driven to press and slide relative to the rebound bracket 4. The pressing element 6 pushes the movable rail 1 to slide open on the fixed rail 2 through the pressing connection assembly. When the movable rail 1 slides closed on the fixed rail 2, the pressing element 6 is driven to move in the direction of the transmission member 7 through the pressing connection assembly.

[0031] The synchronization device 8 includes a synchronization rod 28 that is connected to the transmission member 7. A drawer is provided on the movable rail 1, and the drawer is supported on two movable rails 1. The push-rebound opening and closing mechanism 3 on each movable rail 1 is connected through the synchronization rod 28; when one of the push-rebound opening and closing mechanisms 3 is unlocked, the pushing elements 5, the pressing elements 6, and the transmission member 7 of the two push-rebound opening and closing mechanisms 3 move synchronously through the synchronization rod 28, so that the two movable rails 1 of the drawer can be synchronously elastically slid open on the fixed rail 2.

[0032] The fixed rail 2 is fixed on the cabinet body, and the drawer includes a panel. When the user presses any position of the panel, the two press-rebound opening and closing mechanisms 3 can be triggered to unlock synchronously, which is very sensitive.

[0033] A first engaging portion 30 is provided on the transmission member 7, and a second engaging portion 31 is provided on the synchronization rod 28. The transmission member 7 and the synchronization rod 28 are connected through the matching transmission of the first engaging portion 30 and the second engaging portion 31; a gear forming the second engaging portion 31 is provided on the synchronization rod 28, and the synchronization rod 28 and the gear are arranged as a whole, or the gear is installed on the synchronization rod 28; a rack meshing with the gear is provided on the transmission member 7, and the rack and the transmission member 7 are arranged as a whole, and the rack forms the first engaging portion 30.

[0034] When one of the transmission members 7 moves, it drives the synchronization rod 28 to rotate through the gear. The rotation of the synchronization rod 28 drives another gear to rotate. The rotation of the other gear drives another transmission member 7 to move, thereby unlocking another pushing element 5 and another transmission member 7. When the pushing element 5 and the transmission member 7 move to the corresponding positions, the transmission members 7 on the two movable rails 1 perform synchronous elastic reset.

[0035] By increasing the elastic force of the first elastic member 13 , it can be ensured that the drawer is fully opened on the cabinet body, or after the two movable rails 1 of the drawer slide out a certain distance synchronously, the user can pull the drawer out by hand.
