[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] Referring to Figures 1 - 17 , the present pressing and rebounding device facilitating detachment includes a fixed bracket 1 and a movable buckle part 2. A pushing member 4 is provided on the fixed bracket 1. The pushing member 4 is slidably arranged on the fixed bracket 1, and a telescopic member 9 is provided thereon. The telescopic member 9 slidably expands and contracts on the pushing member 4, and an opening part 40 is provided thereon. A detachable member 20 and a detachable elastic member 21 are provided on the opening part 40; a detachable part 10 is provided on the detachable member 20, and the detachable member 20 elastically rotates or swings on the opening part 40 through the detachable elastic member 21.

[0037] When the movable buckle part 2 is pressed towards the fixed bracket 1, it is mutually buckled with the detachable part 10 through the opening part 40.

[0038] When the movable buckle part 2 moves a certain distance in the opposite direction of the fixed bracket 1, it is separated from the detachable part 10.

[0039] In this embodiment, only by providing a detachable member 20 and a detachable elastic member 21 on the opening part 40 of the telescopic member 9 and using the elastic acting force of the detachable elastic member 21, the detachable member 20 can elastically rotate or swing on the opening part 40, so that the movable buckle part 2 can be mutually buckled or separated from the detachable part 10 through the elastic rotation or swing of the detachable member 20. This not only effectively reduces the number of components, simplifies the assembly process, and reduces the production cost, but also avoids rigid collisions between the movable buckle part 2 and the detachable part 10 during mutual buckling, resulting in easy damage to both or problems such as abnormal noises. At the same time, it can also ensure that the pushing member 4 and the telescopic member 9 can automatically reset when the movable buckle part 2 and the detachable part 10 are separated, ensuring that the pressing and rebounding device can stably achieve the functions of pressing and rebounding to open and automatically reset after opening.

[0040] Specifically, one end of the snap-off elastic member 21 elastically acts on the telescopic member 9, and the other end elastically acts on the snap-off member 20; the snap-off portion 10 is arranged on the snap-off member 20 in the direction of the opening portion 40; the snap-off member 20 elastically rotates or swings on the telescopic member 9 through the snap-off elastic member 21, and when elastically rotating or swinging, it is mutually snapped or separated from the movable snap portion 2 through the snap-off portion 10.

[0042] When the movable snap portion 2 is pressed towards the fixed support 1, it is guided into the opening portion 40 through the opening guiding portion 41, acts on the snap-in guiding portion 22, and drives the snap-off member 20 to elastically rotate or swing on the telescopic member 9. When the snap-off member 20 elastically rotates or swings, the movable snap portion 2 is mutually snapped with the snap-off portion 10.

[0043] When the movable snap portion 2 moves a certain distance in the opposite direction of the fixed support 1, it acts on the snap-off portion 10 and directly drives the snap-off member 20 to rotate or swing on the telescopic member 9 against the elastic force of the snap-off elastic member 21. When the snap-off member 20 rotates or swings, the movable snap portion 2 is mutually forced to separate from the snap-off portion 10.

[0044] In addition to the forced separation between the movable snap portion 2 and the snap-off portion 10, a guiding separation can also be achieved. That is, a separation assisting member 42 is arranged on the telescopic member 9 or the pushing member 4. The separation assisting member 42 elastically slides on the telescopic member 9 or the pushing member 4, and a separation guiding portion 43 is arranged thereon; a separation guiding and mating portion 44 is arranged on the snap-off member 20 and interacts with the separation guiding portion 43 through the separation guiding and mating portion 44; when the movable snap portion 2 moves a certain distance in the opposite direction of the fixed support 1, it acts on the snap-off portion 10, and drives the separation assisting member 42 to slide on the telescopic member 9 or the pushing member 4 through the cooperation of the separation guiding and mating portion 44 and the separation guiding portion 43. When the separation assisting member 42 slides to a certain position, it is positioned on the telescopic member 9 and / or the pushing member 4. When the movable snap portion 2 slides and is positioned by the separation assisting member 42 and continues to move in the opposite direction of the fixed support 1, it drives the snap-off member 20 to overcome the elastic force of the snap-off elastic member 21 and guide the rotation or swing on the telescopic member 9 through the cooperation of the separation guiding and mating portion 44 and the separation guiding portion 43. When the snap-off member 20 rotates or swings, the movable snap portion 2 is mutually guided to separate from the snap-off portion 10.

[0045] A sliding positioning portion 45 is arranged on the separation assisting member 42, and a sliding positioning and mating portion 46 is arranged on the telescopic member 9 and / or the pushing member 4; when the separation assisting member 42 slides to a certain position on the telescopic member 9 or the pushing member 4, it is positioned on the sliding positioning and mating portion 46 through the sliding positioning portion 45.

[0046] A separation auxiliary elastic member 47 is further provided between the separation auxiliary member 42 and the telescopic member 9 or the pushing member 4. One end of the separation auxiliary elastic member 47 elastically acts on the separation auxiliary member 42, and the other end elastically acts on the telescopic member 9 or the pushing member 4; when the movable buckle portion 2 and the buckling and separating portion 10 are separated at least, the separation auxiliary member 42 is reset and slides on the telescopic member 9 or the pushing member 4 through the separation auxiliary elastic member 47.

[0047] In this embodiment, the opening guiding portion 41 is arranged in an outwardly expanding manner on the opening portion 40; the movable buckle portion 2 is a U-shaped cylinder and is correspondingly arranged with the opening portion 40, and can be movably arranged on the opening portion 40 in a deflectable manner, that is, the movable buckle portion 2 can be deflected and introduced into or disengaged from the opening portion 40, so as to facilitate the mutual buckling or separation between the movable buckle portion 2 and the buckling and separating portion 10.

[0048] A heart-shaped groove portion 3 and a reset member 6 are arranged on the fixed bracket 1; a first socket portion 13 and a second socket portion 14 are arranged on the pushing member 4, and the first socket portion 13 and the second socket portion 14 are arranged independently of each other.

[0049] The first socket portion 13 is located inside the fixed bracket 1, and a pushing elastic member 5 is arranged thereon. One end of the pushing elastic member 5 elastically acts on the fixed bracket 1, and the other end is elastically sleeved on the first socket portion 13; the pushing member 4 elastically slides on the fixed bracket 1 through the pushing elastic member 5, and a sliding portion 8 is arranged thereon. When the pushing member 4 elastically slides, the sliding portion 8 stays and slides along the track of the heart-shaped groove portion 3.

[0050] One end of the second socket portion 14 at least partially extends out of the fixed bracket 1; one end of the telescopic member 9 at least partially extends out of the second socket portion 14 and is buckled or separated from the movable buckle portion 2 through the buckling and separating portion 10. The other end of the telescopic member 9 is sleeved and slidably telescoped in the second socket portion 14, and a linkage assembly is arranged between the telescopic member 9 and the reset member 6. The telescopic member 9 and the reset member 6 are mutually driven and connected through the linkage assembly.

[0051] The linkage assembly includes a linkage member 11 and a steering member 12; one end of the linkage member 11 is cooperatively connected with the telescopic member 9, and the other end is cooperatively connected with the reset member 6 after bypassing the steering member 12.

[0052] A sliding member 15 and a sliding-out positioning portion 16 are arranged on the pushing member 4; a sliding-out positioning cooperation portion 17 is arranged on the fixed bracket 1; a staying area and a sliding area are arranged on the heart-shaped groove portion 3; the sliding portion 8 is arranged on the sliding member 15; the sliding member 15 is rotatably or swingably arranged on the pushing member 4 and stays on the staying area or slides on the sliding area through the sliding portion 8, so as to realize the positioning and retraction of the pushing member 4 into the fixed bracket 1 or the sliding and extension of the pushing member 4 out of the fixed bracket 1.

[0053] When the movable buckle part 2 is pressed towards the fixed bracket 1, it engages with the engaging and disengaging part 10, drives the pushing member 4 to slide towards the fixed bracket 1, drives the sliding part 8 to slide out of the staying area and slide on the sliding area. When the pushing member 4 slides on the sliding area, the pushing elastic member 5 drives the pushing member 4 to slide out a certain distance in the opposite direction of the fixed bracket 1, and at the same time drives the telescopic member 9 and the movable buckle part 2 to slide along, and is positioned on the sliding positioning and mating part 17 through the sliding-out positioning part 16. Among them, when the telescopic member 9 slides out a certain distance, the linkage member 11 and the steering member 12 cooperate to drive the reset member 6 to slide a certain distance on the fixed bracket 1 and be positioned on the pushing member 4.

[0054] A reset driving part 18 is arranged on the reset member 6; a reset mating part 19 is arranged on the pushing member 4; a reset elastic member 7 is arranged on the fixed bracket 1. One end of the reset elastic member 7 elastically acts on the fixed bracket 1, and the other end elastically acts on the reset member 6.

[0055] When the reset member 6 slides a certain distance on the fixed bracket 1, it is positioned on the reset mating part 19 through the reset driving part 18. When the movable buckle part 2 drives the telescopic member 9 to continue sliding in the opposite direction of the fixed bracket 1, it drives the reset member 6 to continue sliding on the fixed bracket 1. When the reset member 6 continues to slide, the reset driving part 18 and the reset mating part 19 cooperate to drive the pushing member 4 to slide in the direction of the fixed bracket 1 for reset. When the pushing member 4 slides for reset, it drives the sliding part 8 to slide out of the sliding area and stay in the staying area, so as to realize the reset sliding of the pushing member 4 and be positioned and retracted into the fixed bracket 1.

[0056] When the movable buckle part 2 is separated from the engaging and disengaging part 10 when the pushing member 4 is positioned and retracted into the fixed bracket 1 and continues to slide in the opposite direction of the fixed bracket 1, the reset member 6 slides on the fixed bracket 1 for reset through the reset elastic member 7 when the movable buckle part 2 and the engaging and disengaging part 10 are separated, and drives the telescopic member 9 to slide in the direction of the fixed bracket 1 for reset and retract into the pushing member 4 through the cooperation of the linkage member 11 and the steering member 12 when sliding for reset, so as to realize the reset sliding of the telescopic member 9 and the reset member 6 and be positioned on the fixed bracket 1.

[0057] The elastic force generated by the pushing elastic member 5 on the pushing member 4 is greater than the elastic force generated by the reset elastic member 7 on the reset member 6, so that the pushing member 4 can overcome the elastic force of the reset elastic member 7 through the pushing elastic member 5 and slide out a certain distance in the opposite direction of the fixed bracket 1 when the movable buckle part 2 is pressed. Among them, the telescopic member 9 and the movable buckle part 2 slide in the same direction when the pushing member 4 slides out of the fixed bracket 1, and the reset member 6 slides in the opposite direction when the pushing member 4 slides out of the fixed bracket 1.

[0058] This structural product can be widely applied to furniture products such as side-opening doors, up-flipping doors, or drawers of furniture. In this embodiment, a side-opening door of furniture is taken as an example, which further includes a furniture cabinet body X and a furniture door body Y. A hinge is provided between the furniture cabinet body X and the furniture door body Y, and they are laterally opened and closed in cooperation with each other through the hinge.

[0059] Its working principle is as follows:

[0060] The furniture door body Y is closed on the furniture cabinet body X. When the user presses the furniture door body Y, the movable buckle portion 2 moves towards the fixed bracket 1 and engages with the disengaging portion 10. At the same time, the movable buckle portion 2 also drives the pushing member 4 to slide towards the fixed bracket 1. When the pushing member 4 slides, it drives the sliding portion 8 to slide out of the staying area and slide on the sliding area. At this time, the pushing member 4 slides out a certain distance in the opposite direction of the fixed bracket 1 through the pushing elastic member 5, and at the same time drives the telescopic member 9 and the movable buckle portion 2 to slide along, and is positioned on the sliding-out positioning and mating portion 17 through the sliding-out positioning portion 16, that is, the furniture door body Y will automatically open a certain angle relative to the furniture cabinet body X; among them, when the telescopic member 9 slides out a certain distance, it drives the reset member 6 to slide a certain distance on the fixed bracket 1 through the cooperation of the linkage member 11 and the turning member 12, and is positioned on the reset mating portion 19 through the reset driving portion 18. Its state change process is as Figures 10 - 13 shown.

[0061] When the user pulls open the furniture door body Y and drives the telescopic member 9 to continue sliding in the opposite direction of the fixed bracket 1 through the movable buckle portion 2, and drives the reset member 6 to continue sliding on the fixed bracket 1. When the reset member 6 continues to slide, it drives the pushing member 4 to reset and slide towards the fixed bracket 1 through the cooperation of the reset driving portion 18 and the reset mating portion 19. When the pushing member 4 resets and slides, it drives the sliding portion 8 to slide from the sliding area and stay in the staying area, so as to realize the reset sliding of the pushing member 4 and its positioning and retraction into the fixed bracket 1. Its state change process is as Figures 12 - 15 shown.

[0062] When the user continues to pull open the furniture door body Y, at this time, due to the positioning effect of the telescopic member 9, it cannot continue to slide, so the movable buckle portion 2 will separate from the disengaging portion 10. When the movable buckle portion 2 and the disengaging portion 10 are separated, the reset member 6 resets and slides on the fixed bracket 1 through the reset elastic member 7, and when resetting and sliding, it drives the telescopic member 9 to reset and slide towards the fixed bracket 1 and retract into the pushing member 4 through the cooperation of the linkage member 11 and the turning member 12, so as to realize the reset sliding of the telescopic member 9 and the reset member 6 and their positioning on the fixed bracket 1. Its state change process is as Figures 15 - 17 shown.

[0063] Among them, Figure 11 , Figure 13 , Figure 15 , Figure 17 are respectivelyFigure 10 , Figure 12 , Figure 14 , Figure 16 The relationship status of the fixed bracket 1 and the movable buckle part 2 of Figure 16 .

[0064] By utilizing the cooperation between the sliding part 8 and the staying area and the sliding area on the heart-shaped groove part 3, the user can directly press the movable buckle part 2 with any part of the body, enabling the pushing member 4 to slide out a certain distance in the opposite direction of the fixed bracket 1, thereby achieving the automatic opening of the furniture door body Y, effectively avoiding the problems of increased production costs and affecting the aesthetic appearance of the furniture caused by installing handles on the furniture door body Y.

[0065] At the same time, the pushing member 4, the reset member 6, and the displacement member 31 are respectively assembled by using the pushing member sliding groove 24, the reset member sliding groove 25, and the displacement member sliding groove 39. Meanwhile, the pushing elastic member 5 and the telescopic member 9 are assembled on the pushing member 4 by using the first socket part 13 and the second socket part 14, thereby effectively simplifying the assembly process of the entire energy storage and rebound device, reducing production costs. Moreover, by utilizing the linkage effect of the linkage member 11 and the steering effect of the steering member 12, an effective driving connection is formed between the telescopic member 9 and the reset member 6. At the same time, the internal space of the fixed bracket 1 can be reasonably utilized, thereby effectively simplifying the structure of the energy storage and rebound device, reducing the volume, and improving the connection compactness between components.

[0066] Furthermore, when the telescopic member 9 slides alone in the opposite direction of the fixed bracket 2, it can drive the reset member 6 to slide on the fixed bracket 1 through the cooperation of the linkage member 22 and the steering member 12. Thus, the reset member 6 drives the pushing member 4 to reset and slide through the cooperation of the reset driving part 18 and the reset cooperation part 19, and is positioned and indented into the fixed bracket 1 to ensure that the pushing member 4 can automatically reset, avoiding the problems of component damage or user injury caused by the inability of the pushing member 4 to reset and easy user touch, making the user's use safer and more convenient.

[0067] And when the telescopic member 9 extends out of the pushing member 4 and the movable buckle part 2 is separated from the buckle separation part 10, the reset member 6 can slide on the fixed bracket 1 through the reset of the reset elastic member 7. At the same time, the cooperation of the linkage member 11 and the steering member 12 can also be used to drive the telescopic member 9 to follow the reset, ensuring that the telescopic member 9 and the reset member 6 can automatically reset and wait for the next pressing operation. This not only improves the working stability of the entire energy storage and rebound device, enabling it to meet the pressing and opening of the furniture door body Y, but also reduces the problems of component damage or injury caused by accidental user touch, further improving the user's use safety and convenience. At the same time, since the pushing member 4 and the telescopic member 9 automatically reset and retract into the fixed bracket 1 after the furniture door body Y is opened, it will not hinder the closing of the furniture door body Y, enabling the furniture door body Y to close smoothly and achieve a perfect fit.

[0068] The fixed bracket 1 is provided with a sliding groove 24 for the pushing member and a sliding groove 25 for the reset member. The sliding groove 24 for the pushing member and the sliding groove 25 for the reset member are independently arranged.
