[0032] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted again that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Example 1

[0034] like Figure 1-3 The present invention proposes a follower-driven flip-opening mechanism, comprising a drive rod 41, a drive component assembly, a follower component assembly, and a connecting rod 31 connecting the drive component assembly and the follower component assembly; wherein:

[0035] The active component assembly includes an active component 11 and an active component support 12. The active component 11 is a part on large equipment, such as a hatch on an aircraft; or, depending on actual needs, the active component 11 is a small component; or the active component 11 can be made into an irregular shape and connected to a fixed component to be rotated, such as a Y-shaped body. Preferably, the bottom end of the active component 11 has a horizontally penetrating shaft hole, within which a rotating shaft 15 is provided, and the active component 11 is connected to the aforementioned fixed component via the rotating shaft 15. The top end of the active component 11 has a horizontally penetrating shaft hole, within which a rotating shaft 14 is provided. A drive rod 41 is sleeved on the rotating shaft 14, and a driving load is applied to the drive rod 41, causing the active component 11 to rotate around the rotating shaft 15, thereby realizing the flipping motion of the active component 11. Preferably, the drive rod 41 is a hydraulic drive rod or an electric drive rod, and a crank is provided between the hydraulic drive rod or the electric drive rod and the rotating shaft 14 to limit the range of motion of the drive rod 41. The drive component support 12 is arranged on the end face of the drive component 11 and is used to connect the drive component 11 and the connecting rod 31. The installation method includes, but is not limited to, welding and gluing. Preferably, the drive component support 12 is located on the end face between the top and bottom shaft holes of the drive component 11, that is, on the end face of the drive component 11 between the rotating shaft 14 and the rotating shaft 15. The front end of the drive component support 12 is hinged to one end of the connecting rod 31 through the drive component rotary joint 13, so that the drive component 11 drives the connecting rod 31 to move.

[0036] The follower assembly includes a follower 21 and a follower support 22. Similar to the driving component 11, the follower 21 is a component on large equipment, such as a cover on an aircraft; or, depending on actual needs, the follower 21 is a small part; or the follower 21 can be made into an irregular shape and connected to a fixed component to be flipped open, such as a square shape. Preferably, the upper edge of the follower 21 is provided with a rocker arm 24, through which the follower 21 is connected to the fixed component, and the follower 21 rotates around the rocker arm 24. Preferably, there are two or more rocker arms 24 to ensure a stable connection between the follower 21 and the fixed component, thereby stabilizing the movement of the follower 21. The follower support 22 is arranged on the end face of the follower 21 and is used to connect the follower 21 to the connecting rod 31. The installation method includes, but is not limited to, welding and gluing. The front end of the follower support 22 is hinged to the other end of the connecting rod 31 through the follower rotary joint 23, so that the connecting rod 31 drives the follower 21 to move.

[0037] The connecting rod 31 includes a driving member connecting rod 31a and a follower connecting rod 31b. The driving member connecting rod 31a is closer to the driving member 11, and the follower connecting rod 31b is closer to the follower member 21. The shaft diameter of the driving member connecting rod 31a is larger than the shaft diameter of the follower connecting rod 31b. The driving member connecting rod 31a is sleeved on the follower connecting rod 31b, so that the driving member connecting rod 31a and the follower connecting rod 31b generate relative motion in the axial and radial directions.

[0038] Depending on the application, our organization uses different materials, such as aluminum alloy, rubber, or plastic.

[0039] In this embodiment, a load is applied to the drive rod 41, which drives the active component assembly to rotate around the rotation axis 15. This causes the active component assembly to drive the connecting rod 31 to produce longitudinal and lateral movements via the active component rotary joint 13. Simultaneously, tensile and shear forces are generated on the connecting rod 31 body, causing the active component connecting rod 31a and the follower connecting rod 31b to move and rotate relative to each other. Then, through the follower rotary joint 23, the follower assembly is driven to perform opening, closing, and flipping movements around the rocker arm 24 in directions different from those of the active component assembly. The specific motion is as follows:

[0040] like Figure 2 As shown, when normally opened, the drive rod 41 provides a driving load to the side away from the follower assembly, driving the active component assembly to flip to the side away from the follower assembly, causing the connecting rod 31 to move in both longitudinal and lateral directions. At the same time, the connecting rod 31 body is stretched and rotated relative to each other, thereby driving the entire follower flipping mechanism to flip and open around the rocker arm 24 to the side away from the active component assembly, realizing the flipping and opening of the active component 11 and the follower 21 in different directions.

[0041] like Figure 3 As shown, when normally closed, the drive rod 41 provides a driving load towards the side closer to the active component assembly, driving the active component assembly to flip towards the side closer to the follower component assembly, causing the connecting rod 31 to move in the opposite direction to when it is open. At the same time, the body of the connecting rod 31 retracts and rotates in the opposite direction, thereby driving the entire follower flipping mechanism to flip and close around the rocker arm 24 towards the side closer to the active component assembly, realizing the flipping and closing of the active component 11 and the follower component 21 in different directions.

[0042] Preferably, by adjusting the magnitude of the driving load on the drive rod 41, the flipping angle of the driving member 11 can be changed, thereby changing the flipping opening angle of the follower member 21. Specifically, increasing the driving load on the drive rod 41 increases the flipping opening angle of the driving member 11, causing the extension length and relative rotation angle of the connecting rod 31 to increase, and thus the flipping opening angle of the follower member 21 to increase. Conversely, decreasing the driving load on the drive rod 41 decreases the flipping opening angle of the driving member 11, causing the extension length and relative rotation angle of the connecting rod 31 to decrease, and thus the flipping opening angle of the follower member 21 to decrease.

[0043] Preferably, by adjusting the position of the active component support 12 on the end face of the active component 11, the flipping direction or angle of the active component 11 can be changed; by adjusting the position of the follower support 22 on the end face of the follower 21, the flipping opening direction or angle of the follower 21 can be changed.

[0044] Example 2

[0045] like Figure 4-6 As shown, in this embodiment, the driving member rotary joint 13 includes a first driving member rotational shaft 13a, a driving member crank 13b, and a second driving member rotational shaft 13c. This driving member rotary joint 13 has two rotational degrees of freedom; specifically, as shown... Figure 5 As shown, the first rotating shaft 13a of the active component is a cross-shaped rigid structural component, including a transverse shaft and a longitudinal shaft arranged perpendicularly to each other. Figure 4 As shown, the front end of the drive component support 12 has a through-hole, and the aforementioned transverse shaft is disposed within the through-hole, rotating around its own central axis. The drive component crank 13b is sleeved on the aforementioned longitudinal shaft, arranged perpendicularly to both the transverse and longitudinal shafts, and is fixed to the longitudinal shaft by welding or by machining into an integral structure, thereby allowing the drive component crank 13b to rotate around the aforementioned transverse shaft; the second rotating shaft 13c of the drive component is disposed within the through-hole of the drive component crank 13b. Figure 6 As shown, both ends of the connecting rod 31 are provided with shaft holes; the shaft hole located at the end of the driving member connecting rod 31a is the driving member connecting rod shaft hole, and the second rotating shaft 13c of the driving member passes through the driving member connecting rod shaft hole, so that the driving member crank 13b is hinged to the driving member connecting rod 31a through the second rotating shaft 13c of the driving member. The first rotating shaft 13a of the driving member and the second rotating shaft 13c of the driving member are perpendicular to each other, so that the driving member 11 drives the connecting rod 31 to move in both the lateral and longitudinal directions through the driving member rotary joint 13.

[0046] like Figure 4 As shown, the follower rotary joint 23 includes a first follower rotational shaft 23a, a follower crank 23b, and a second follower rotational shaft 23c. This follower rotary joint 23 has two rotational degrees of freedom; specifically, as shown... Figure 6 As shown, both ends of the connecting rod 31 are provided with shaft holes. The shaft hole at the end of the follower connecting rod 31b is the follower connecting rod shaft hole. The first rotating shaft 23a of the follower passes through both the follower connecting rod shaft hole and the shaft hole at one end of the follower crank 23b. The follower crank 23b is hinged to the follower connecting rod 31b through the first rotating shaft 23a, so that the connecting rod 31 drives the follower crank 23b to rotate around the first rotating shaft 23a. The second rotating shaft 23c of the follower is a cross-shaped rigid structure, including a longitudinal shaft and a transverse shaft arranged perpendicularly to each other; as shown... Figure 4As shown, the follower crank 23b is sleeved on the longitudinal shaft and arranged perpendicularly to both the transverse and longitudinal shafts. It can be fixed to the longitudinal shaft structure by welding or other methods, or processed into an integral structure. The transverse shaft structure passes through the shaft hole at the front end of the follower support 22, allowing the follower support 22 to rotate around the second follower rotation axis 23c. The first follower rotation axis 23a and the second follower rotation axis 23c are perpendicular to each other, causing the connecting rod 31 to drive the follower 21 to move in both the longitudinal and transverse directions through the follower rotary joint 23. This enables the follower 21 to perform flipping and opening / closing movements in directions and angles different from those of the driving member 11. The movement of this mechanism is precise, coordinated, and does not interfere with each other. The other parts of this embodiment are set up exactly the same as in embodiment 1.

[0047] Example 3

[0048] The only difference between this embodiment and Embodiment 2 is the difference between the driving member rotary joint 13 and the follower rotary joint 23. Specifically, the driving member rotary joint 13 is a ball joint with three rotational degrees of freedom. The driving member support 12 is connected to the driving member connecting rod 31a via the ball joint, so that the driving member 11 drives the connecting rod 31 to move in multiple directions. The follower rotary joint 23 is a ball joint with three rotational degrees of freedom. The follower support 22 is connected to the follower connecting rod 31b via the ball joint, so that the follower 21 is driven by the connecting rod 31 to move in multiple directions. This enables the follower 21 to perform flipping and opening / closing movements in multiple directions and angles different from the driving member 11. The other parts are set up exactly the same as in Embodiment 2.

[0049] Example 4

[0050] The only difference between this embodiment and Embodiment 1 is that the drive rod is replaced with a rotary drive. Specifically, according to the actual space requirements, a rotary drive, including but not limited to a torsion spring, a motor, etc., is directly sleeved on the rotating shaft 14 to drive the active component 11.

[0051] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
