Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] This invention reference Figure 1 , Figure 2 As shown, a door opener structure is disclosed, including a housing 1. The housing 1 has an upper cover 11 and a lower cover 12, and an accommodating space 13 is provided between the upper cover 11 and the lower cover 12. The lower cover 12 is provided with a first track 121, a second track 122, a third track 123, and a fourth track 124. The first track 121 is provided with four grooves, including a first groove 1211, a second groove 1212, a third groove 1213, and a fourth groove 1214. The fourth track 124 is provided with a stop portion 1241.

[0025] The starting device 2 is disposed within the accommodating space 13. The starting device 2 is provided with a first slider 21, which is disposed within a second track 122 and can move within the second track 122. The starting device 2 is provided with a first elastic element 22, which is connected to the first slider 21. The starting device 2 is provided with a connecting element 23, which is disposed within the first track 121 and can move within the first track 121. The connecting element 23 is connected to the first slider 21 and is provided with a hook 231. The starting device 2 is provided with a starting element 24, which is disposed at the position of the fourth groove 1214.

[0026] The driving member 3 is located within the third track 123 and can move within the third track 123. The driving member 3 has a hooked part 31 and a pushed part 32. The pushing device 4 is located within the accommodating space 13 and has a pushing rod 41 connected to the lower cover 12. The pushing rod 41 has a groove 411. The pushing device 4 has a second slider 42, which has a fifth track 421. The pushing device 4 has a second elastic member 43 connected to the second slider 42. The pushing device 4 has a limiting member 44 connected to the second slider 42 and can move within the fourth track 124 and the fifth track 421.

[0027] The connector 5 is connected to the driving member 3 and the push rod 41 at both ends respectively; when the door panel 6 is in the open state, the hook 231 and the hooked part 31 are connected by an engaging method (e.g., Figure 8 (as shown); the push rod 41 can rotate on the lower cover 12, and a wheel 412 can be provided at the end of the push rod 41. The wheel 412 can reduce the friction between the rotating rod 41 and the door panel 6.

[0028] One end of the first elastic member 22 is connected to the first slider 21, and the other end can be fixed to the lower cover 12, or the lower cover 12 is provided with a first fixing member 125, and the other end of the first elastic member 22 can be provided on the first fixing member 12; one end of the second elastic member 43 is connected to the second slider 42, and the other end can be fixed to the lower cover 12, or the lower cover 12 is provided with a second fixing member 126, and the other end of the second elastic member 43 can be provided on the second fixing member 126; the first elastic member 22 can be a tension spring, and the second elastic member 43 can be a tension spring; the starting member 24 can be exposed outside the housing 1 or just aligned with the housing 1, as long as the door panel 6 can squeeze the starting member 24 when pressed, the present invention can be implemented.

[0029] SeeFigure 1 , Figure 3 and Figure 4 , Figure 1 This invention shows the door panel 6 when it is opened. When the door panel 6 is closed, the driving member 3 and the push rod 41 are connected via the connecting member 5. The push rod 41 causes the driving member 3 to move to the right. Because the hooked part 31 of the driving member 3 engages with the hook part 231 of the connecting member 23, the connecting member 23 also moves to the right, thereby driving the first slider 21 to the right. This also stretches the first elastic member 22 until both ends of the connecting member 23 move to the positions of the second groove 1212 and the fourth groove 1214 of the first track 121, respectively. The pulling force of the hook part 231 and the hooked part 31 causes both ends of the connecting member 23 to rotate towards the second groove 1212 and the fourth groove 1214 and become locked. Figure 4 As shown.

[0030] At the same time, when the door panel 6 is opened, the limiting member 44 will be located in the groove 411 of the push rod 41 (e.g. Figure 1 As shown), when the door panel 6 is closed, the pushing member 41 will also drive the limiting member 44 to move, which in turn causes the limiting member 44 to drive the second slider 42 to move, thus stretching the second elastic member 43 until the limiting member 44 is engaged with the stop part 1241 of the fourth track 124, completing the stretching of the second elastic member 43. Meanwhile, the pushing rod 41 continues to be driven by the door panel 6 to close, as shown. Figure 4 As shown.

[0031] By closing the door panel 6, the first elastic element 22 and the second elastic element 43 are stretched, thereby achieving a two-stage energy storage effect.

[0032] See Figure 5 , Figure 6 When opening the door panel 6, simply press the door panel 6. The door panel 6 presses against the actuating member 24, causing the actuating member 24 to push the linkage member 23 out of the fourth groove 1214, allowing the linkage member 23 to return to the first track 121. The force of the first elastic member 22 moves the first slider 21 and the linkage member 23 to the left. The first slider 21 also pushes the driven part 32 of the driving member 3 to the left. The driving member 3 then drives the push rod 41 to rotate counterclockwise, opening the door panel 6. When the groove 411 of the push rod 41 disengages the limiting member 44 from the stop part 1241 of the fourth track 124, the second elastic member 43 provides force again, causing the limiting member 44, which is stuck in the groove 411 of the push rod 41, to move along the fifth track 421 and the fourth track 124, and driving the push rod 41 to continue rotating counterclockwise until the door panel 6 is fully open. Figure 7 As shown.

[0033] The actuating component 24 may be equipped with a spring 241, which allows the actuating component 24 to return to its original position after being compressed; the second slider 42 may be equipped with a buffer device 422, which prevents the door panel 6 from being opened with excessive force, thus avoiding injury or damage to people or walls.

[0034] See Figure 2 , Figure 7 , Figure 8 As shown, when the door panel 6 is fully opened, the hooked part 31 of the driving member 3 will press the hook part 231 of the linkage 23, causing both ends of the linkage 23 to rotate towards the first groove 1211 and the third groove 1213. After the hooked part 31 of the driving member 3 passes through, the hook part 231 and the hooked part 31 will engage again and return to the starting position. Figure 1 The state.

[0035] The lower cover 12 may be provided with a return member 127, which is located in the third groove 1213. When one end of the linkage 13 is in the third groove 1213, the return member 127 will compress inward. When the drive member 3 passes through, the return member 127 will push one end of the linkage 23 outward, so that the linkage 23 returns to the horizontal state and engages with the drive member 3.

[0036] This invention can be installed inside cabinet 61, such as... Figure 9 As shown, pressing the door panel 6 of the cabinet 61 with this invention will open the door panel. This invention is not limited to the cabinet 61; it can be implemented in any device that has a door panel.

[0037] By combining the above, the present invention can achieve the effect of opening the door panel 6 by pressing it, and the buffering effect when closing the door is directly achieved by the existing hinge. Therefore, there is no need to set up a damper to provide a buffering effect when closing the door. The present invention can also provide a buffer device 422 on the second slider 42, so that when opening the door panel 6, there is no need to worry about injury or damage to people or walls caused by excessive force.
