It is said that the above structure can effectively simplify the overall structure of the push-rebound device, reduce the overall volume, thereby reducing the production and assembly costs of the push-rebound device, and also reduce the storage space inside the furniture occupied by it during assembly; however, in actual use, there is no special requirement for the installation position of the push-rebound device, and it may be installed in a vertical, inclined, or inverted manner. When in use, the installed sliding part will be difficult or impossible to elastically telescopically slide along the trajectory of the heart-shaped slide groove in a sequential direction due to its own gravity, the elastic force of the elastic member, or the pressing force, that is, the sliding part will be stuck on the heart-shaped slide groove, and then it is impossible to ensure that the push-rebound device can achieve the effect of push-rebound opening and sliding closing every time it is used, affecting the user's experience. Therefore, it is necessary to make further improvements. Summary of the invention

[0008] One end of the movable part is rotatably or swingably arranged on the pushing element or the assembly part, the middle part relies on the first step and / or the second step, and elastically relies on the pushing element through the first step and / or the second step, and the other end of the movable part is provided with a sliding part; the pushing element drives the movable part to follow the movement when it elastically telescopes and slides, and when the movable part moves, the cooperation of the first step and the second step limits the sliding part to slide and / or position along the trajectory of the heart-shaped slide groove in only one sequential direction.

[0009] The heart-shaped slide groove is at least provided with a lower limit sliding area, a lower conversion position, an inclined guiding area, and a heart-shaped stopping area.

[0010] When the pushing element slides into the rebound support, it drives the movable part to slide in the direction of the heart-shaped sliding groove. When the movable part slides to a certain position, the sliding part is limited to slide into the lower limit sliding area. When the sliding part slides to a certain position in the lower limit sliding area, it slides along the trajectory of the lower conversion position. The movable part limits the sliding part located at the lower conversion position to only slide onto the inclined guide area through the action of the first step, and finally slides into and stays in the heart-shaped staying area through the inclined guiding action of the inclined guide area.

[0011] The push element is positioned and closed on the rebound bearing when the sliding portion stays in the heart-shaped stay area.

[0012] The heart-shaped slide groove is also provided with an upper conversion position and an upper limit position sliding area.

[0013] When the sliding part stays in the heart-shaped staying area and the pushing element presses and slides relative to the rebound support, the sliding part is driven by the pushing element to slide out of the heart-shaped staying area and slide along the trajectory of the upper conversion position; the movable part limits the sliding part located at the upper conversion position to only slide to the upper limit sliding area through the action of the second step.

[0018] The present invention improves the above structure by utilizing the first step and the second step of the elastic plastic part to elastically lean on the movable part, and the movable part elastically leans on the push element, so that a mutual elastic action relationship is formed between the movable part and the elastic plastic part, which not only improves the assembly stability between the movable part and the push element, but also enables the movable part to perform limiting movement. When the push element telescopically slides on the rebound support, the movable part can move together with the push element, and the first step and the second step are cooperated to limit the sliding part to slide and / or position along the track of the heart-shaped slide groove in a sequential direction, thereby avoiding the movable part from being difficult or even unable to slide along the track of the heart-shaped slide groove in a sequential direction due to its own gravity, or the elastic force of the elastic part, or the pressing force, and getting stuck on the heart-shaped slide groove, thereby ensuring that the push element can rebound to open and slide closed on the rebound support under any circumstances, improving the stability of the product, and making the user's use more convenient, safe and reliable.

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] See also Figure 1-Figure 16 The energy storage rebound structure includes a rebound support 1, an elastic element 2 and a pushing element 3. The rebound support 1 is provided with a heart-shaped slide groove 4; the elastic element 2 elastically acts on the rebound support 1 and the pushing element 3 respectively; the pushing element 3 is provided with an elastic plastic part 5 and a movable part 6; the elastic plastic part 5 is provided with a first step 7 and a second step 8; the pushing element 3 slides on the rebound support 1 through the elastic expansion and contraction of the elastic element 2, and drives the movable part 6 to slide and / or position along the trajectory of the heart-shaped slide groove 4 in a sequential direction defined by the cooperation of the first step 7 and the second step 8 when sliding.

[0032] Specifically, the elastic-plastic portion 5 elastically relies on the movable member 6 via the first step 7 and / or the second step 8 ; the movable member 6 elastically relies on the push element 3 via the first step 7 and / or the second step 8 .

[0033] The first step 7 and the second step 8 of the elastic plastic portion 5 are elastically supported on the movable member 6, and the movable member 6 is elastically supported on the pushing element 3, so that a mutually elastic relationship is formed between the movable member 6 and the elastic plastic portion 5, which not only improves the assembly stability between the movable member 6 and the pushing element 3, but also enables the movable member 6 to perform limiting activities.

[0034] Furthermore, the push element 3 is also provided with an assembly part 9 , which is made of a material with certain elasticity or plasticity, is fixedly arranged on the push element 3 , and has an elastic-plastic part 5 extending in the direction of the heart-shaped slide groove 4 .

[0035] One end of the movable part 6 is rotatably or swingably arranged on the pushing element 3 or the assembly part 9, the middle part relies on the first step 7 and / or the second step 8, and elastically relies on the pushing element 3 through the first step 7 and / or the second step 8, and the other end of the movable part 6 is provided with a sliding part 10; the pushing element 3 drives the movable part 6 to follow the movement when it elastically telescopes and slides, and when the movable part 6 moves, the first step 7 and the second step 8 cooperate to limit the sliding part 10 to slide and / or position along the trajectory of the heart-shaped slide groove 4 in a sequential direction.

[0036] That is, the movable part 6 will move on the rebound support 1 through the driving of the pushing element 3, and slide between the first step 7 and the second step 8 when moving. At the same time, due to the elastic effect of the first step 7 and the second step 8, the sliding part 10 is limited to slide and / or position along the trajectory of the heart-shaped slide groove 4 in a sequential direction.

[0037] Among them, at least one zigzag section is provided between the first step 7 and the second step 8, and the two are connected by at least one zigzag section. That is, the movable member 6 can stably slide between the first step 7 and the second step 8 through at least one zigzag section, avoiding the problem of the movable member 6 getting stuck between the first step 7 and the second step 8, and further ensuring that the sliding part 10 can slide and / or be positioned along the track of the heart-shaped slide groove 4.

[0038] The heart-shaped slide groove 4 of the present embodiment is at least provided with a lower limit sliding area 11 , a lower conversion position 12 , an inclined guide area 13 , and a heart-shaped stop area 14 .

[0039] like Figure 5-Figure 8 As shown, when the pushing element 3 slides into the rebound support 1, it drives the movable part 6 to slide in the direction of the heart-shaped slide groove 4. When the movable part 6 slides to a certain position, the sliding part 10 is limited to slide into the lower limit sliding area 11. When the sliding part 10 slides to a certain position in the lower limit sliding area 11, it slides along the trajectory of the lower conversion position 12; the movable part 6 is limited by the action of the first step 7 to allow the sliding part 10 located at the lower conversion position 12 to slide only onto the inclined guide area 13, and finally slides into and stays in the heart-shaped stay area 14 through the inclined guiding action of the inclined guide area 13.

[0040] When the sliding portion 10 is stopped in the heart-shaped stopping area 14 , the push element 3 is positioned and closed on the rebound bearing 1 .

[0041] The heart-shaped slide groove 4 is also provided with an upper conversion position 15 and an upper limit sliding area 16 .

[0042] like Figure 8 , Fig. 9 As shown, when the sliding portion 10 stays in the heart-shaped staying area 14 and the pushing element 3 is pressed and slid relative to the rebound support 1, the sliding portion 10 is driven by the pushing element 3 to slide out of the heart-shaped staying area 14 and slide along the trajectory of the upper conversion position 15; the movable part 6 limits the sliding portion 10 located at the upper conversion position 15 to only slide to the upper limit sliding area 16 through the action of the second step 8.

[0043] When the sliding portion 10 slides to the upper limit sliding area 16 , the push element 3 is elastically extended and opened on the rebound bearing 1 by the elastic element 2 .

[0044] The lower limit sliding area 11, the inclined guide area 13, the heart-shaped stop area 14, and the upper limit sliding area 16 are connected to each other end to end, that is, the movable part 6 will drive the sliding part 10 to slide in a circle along the lower limit sliding area 11, the inclined guide area 13, the heart-shaped stop area 14, and the upper limit sliding area 16 in one sequential direction through the cooperation of the first step 7 and the second step 8.

[0045] The lower conversion position 12 is located between the lower limit sliding area 11 and the inclined guide area 13 ; the upper conversion position 15 is located between the heart-shaped stay area 14 and the upper limit sliding area 16 .

[0046] A limiting portion 17 is further provided on the pushing element 3 corresponding to the rotation or swing of the movable member 6; the movable member 6 is limited to rotate or swing on the pushing element 3 by the limiting portion 17. The setting of the limiting portion 17 can ensure that the movable member 6 rotates or swings within a limited range, avoiding the problem that the movable member 6 cannot slide and / or be positioned along the track of the heart-shaped slide groove 4 due to excessive rotation or swinging position.

[0047] The rebound support 1 is provided with a connecting member 18, which is fixedly arranged on the rebound support 1 and is provided with a heart-shaped slide groove 4; the connecting member 18 is further provided with a guide portion 19 corresponding to the heart-shaped slide groove 4, and the guide portion 19 is located at the front end of the heart-shaped slide groove 4; the sliding portion 10 is guided by the guide portion 19 to slide into the lower limit sliding area 11 of the heart-shaped slide groove 4. That is, each time the sliding portion 10 slides in the direction of the heart-shaped slide groove 4, it can slide into the lower limit sliding area 11 through the guiding effect of the guide portion 19.

[0048] The elastic element 2 is a compression spring, one end of which elastically acts on the rebound support 1 and / or the connecting member 18, and the other end of which elastically acts on the push element 3, and always generates an elastic force in the direction of the push element 3. Therefore, when the push element 3 is positioned and closed on the rebound support 1, the elastic element 2 is compressed to store energy, and when the push element 3 is pressed, the energy can be released and elastically opened relative to the rebound support 1.
