Description

Technical Field

[0001] The utility model relates to the technical field of simulation aircraft, in particular to an operating handle of a simulation aircraft. Background Art

[0002] The simulation aircraft is the main equipment for simulating the training of real aircraft. An operating handle identical to that in the real aircraft is provided in the simulation aircraft, and different simulation flight scenario trainings are realized by controlling the operating handle. According to different users, the position and angle of the operating handle need to be adjusted so as to adapt to the operation of the operating handle in the current simulation scenario. In the prior art, the operating handle is installed by a single rotating arm. Specifically, when adjusting the position and angle of the operating handle, the single rotating arm requires a relatively large space for synchronous rotation, and the existing adjusting structure is large in volume, occupies space and causes an increase in weight, which is not convenient for realizing a more realistic simulation use of the operating handle. Content of the Utility Model

[0003] The purpose of the utility model is to provide an operating handle of a simulation aircraft, so as to solve the problem that the existing adjusting structure using a single rotating arm for installing the operating handle causes large space occupation and weight increase.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] An operating handle of a simulation aircraft, comprising a handle, a base and a four-bar linkage structure. The four-bar linkage structure is in the shape of a parallelogram. Two first endpoints on one side of the four-bar linkage structure are rotatably connected to the base, and a gear assembly is arranged between two second endpoints on the other side of the four-bar linkage structure; one of the second endpoints is connected with a rotating base, a rotating shaft is rotatably installed on the rotating base, one end of the rotating shaft is connected with the handle, and a first bevel gear is arranged at the other end of the rotating shaft. The first bevel gear is in transmission connection with the gear assembly; a slidable plunger is arranged on the rotating base, and the end of the plunger extending into the rotating base is used for limiting the rotation of the rotating shaft.

[0006] Preferably, the four-bar linkage structure comprises a first connecting rod and a second connecting rod which are arranged in parallel. A third connecting rod is rotatably connected to the first connecting rod, and the third connecting rod is rotatably connected to the second connecting rod; one end of the first connecting rod and the second connecting rod is the first endpoint, and the other end is the second endpoint.

[0007] Preferably, the gear assembly includes a first gear, a second gear, and a second bevel gear. The first gear is rotatably installed at the second end point of the first connecting rod. The second gear and the second bevel gear are coaxially rotatably installed at the second end point of the second connecting rod. The first gear meshes with the second gear, and the second bevel gear meshes with the first bevel gear.

[0008] Preferably, both the first gear and the second gear are half gears.

[0009] Preferably, a convex portion is provided on the first connecting rod, and the convex portion is slidably engaged with the side wall of the second connecting rod.

[0010] Preferably, a plurality of rotation mounting holes evenly distributed along the length direction are formed on both the first connecting rod and the second connecting rod, and strip-shaped holes are provided between adjacent mounting holes.

[0011] Preferably, an installation flange is provided on the base, and fixing holes evenly distributed along the circumferential direction are provided on the installation flange.

[0012] Advantageous effects:

[0013] The rotating base is installed on the base through a four-link structure in the shape of a parallelogram. The handle is installed on the rotating base through a rotating shaft. When the handle rotates relative to the rotating base, the first bevel gear synchronously drives the gear assembly to act, causing the angle of the four-link structure relative to the base to change. That is, when the handle is rotated and adjusted, the four-link structure adaptively adjusts the angle. Thus, the position and angle of the handle can be adjusted in a relatively small space. Moreover, the four-link structure only swings and adjusts within the corresponding plane range, without increasing the adjustment space. At the same time, it also realizes the function of synchronizing with the handle adjustment. After the adjustment is completed, the rotating shaft is stopped by the plunger to lock the adjustment state of the handle.

[0014] The improved structure can not only improve the load-bearing stability of the handle but also reduce the space required for the four-link structure to swing during the adjustment process. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Refer to Figures 1 - 4 As shown, in the embodiment of the present invention, an operation handle 1 of a simulated aircraft is proposed, which is used to be integrated in a simulated aircraft for training operations of the operation handle 1. Specifically, it includes a handle 1, a base 2, and a four-link structure 3. The four-link structure 3 is in the shape of a parallelogram. Two first endpoints on one side of the four-link structure 3 are rotatably connected to the base 2. A gear assembly 7 is provided between two second endpoints on the other side of the four-link structure 3. A rotating base 4 is connected to one of the second endpoints. A rotating shaft 5 is rotatably installed on the rotating base 4. One end of the rotating shaft 5 is connected to the handle 1, and a first bevel gear 6 is provided at the other end of the rotating shaft 5. The first bevel gear 6 is in transmission connection with the gear assembly 7. At the same time, a slidable plunger 8 is provided on the rotating base 4. One end of the plunger 8 extending into the rotating base 4 is used to limit the rotation of the rotating shaft 5. When the position of the handle 1 is adjusted by rotation, first pull the plunger 8 to release the rotation of the rotating shaft 5. The rotation of the handle 1 drives the rotating shaft 5 and the first bevel gear 6 to rotate synchronously. The first bevel gear 6 drives the gear assembly 7 to rotate, so that the second endpoints of the four-link structure 3 generate angular changes, causing the entire four-link structure 3 to move in position relative to the base 2 in a plane. After the position of the handle 1 is adjusted, the four-link structure 3 swings in the plane to adapt to the current state and stably support the handle 1. It can swing within a relatively small space range. After the adjustment is completed, press the plunger 8 to limit the rotation of the rotating shaft 5, so that the handle 1 will not loosen after the position is adjusted, so as to adapt to different users to adjust according to their own operation positions of the handle 1. Among them, the plunger 8 can be a bolt or a sliding pin, and can form a rotation stop for the rotating shaft 5 after being inserted into the rotating base 4.

[0023] The four-bar linkage 3 has good support for the rotating base 4 and the handle 1. At the same time, when the position of the handle 1 is adjusted, it will only swing within a certain range in the plane, and the space it requires is small and controllable.

[0024] Specifically, the four-bar linkage 3 includes a first link 31 and a second link 32 arranged in parallel. A third link 33 is rotatably connected to the first link 31, and the third link 33 is rotatably connected to the second link 32. One end of the first link 31 and the second link 32 is the first end point, and the other end is the second end point. The first end point is rotatably connected to the base 2, and the first link 31 and the second link 32 are always kept parallel during the swinging process through the third link 33, so that the gear assembly 7 at the second end point position remains in the meshing state.

[0025] Among them, the gear assembly 7 includes a first gear 71, a second gear 72 and a second bevel gear 73. The first gear 71 is rotatably installed at the second end point of the first link 31. The second gear 72 and the second bevel gear 73 are coaxially rotatably installed at the second end point of the second link 32. The first gear 71 is meshed and cooperated with the second gear 72. The second bevel gear 73 is meshed and cooperated with the first bevel gear 6. After the first bevel gear 6 is driven by the rotating shaft 5 to rotate, the second bevel gear 73 transmits the power to the second gear 72, and the first gear 71 is driven by the second gear 72 to rotate, so that the angles of the first link 31 and the second link 32 at the second end point change. Finally, the first link 31 and the second link 32 rotate relative to the base 2 to form a position translation, and the first link 31 and the second link 32 are always kept parallel during the translation process.

[0026] Specifically, in order to limit the range of rotation and translation of the first link 31 and the second link 32 relative to the base 2, both the first gear 71 and the second gear 72 are semi-gears to limit the meshing and cooperation range, so that the translation range of the first link 31 and the second link 32 is only within the range where the first gear 71 and the second gear 72 are meshed, further reducing the space occupied by the translation action.

[0027] At the same time, a convex portion 320 is provided on the first link 31. The convex portion 320 is slidably matched with the side wall of the second link 32. The convex portion 320 is used to limit the minimum distance between the first link 31 and the second link 32 during the translation process and can slide to avoid jamming.

[0028] Specifically, a plurality of rotation mounting holes 9 evenly distributed along the length direction are formed in both the first connecting rod 31 and the second connecting rod 32. The rotation mounting holes 9 are used for rotatably mounting the third connecting rod 33. Meanwhile, strip-shaped holes 10 are arranged between adjacent mounting holes. The strip-shaped holes 10 can be used for weight reduction and can also be used to rotatably connect one or both ends of the third connecting rod 33 according to the swing range.

[0029] Specifically, the entire operating handle 1 is mounted on the simulated aircraft through the base 2. An installation flange 21 is provided on the base 2, and fixing holes 22 evenly distributed along the circumferential direction are provided on the installation flange 21. The fixing seat is mounted and fixed through the installation flange 21 and the fixing holes 22.
