Background
The cabin door actuating mechanism is widely used on aircrafts and other carrying equipment, and has various forms according to the requirements of cabin door shapes, opening and closing positions, motion characteristics and the like.
Some devices require that the cabin door is gradually accelerated after being opened at a selected minimum speed in the opening process, and is decelerated or opened in place at a maximum speed before reaching a maximum opening position; the door gradually decelerates after starting to move at a maximum speed during closing and accelerates to or to a minimum speed before closing. However, the conventional door actuating mechanism cannot achieve the above functions, or has many components and a complex structure, so that the actuation is not reliable.

In view of the above-mentioned situation of the prior art, an object of the present invention is to provide a door actuating mechanism, which has few components, is simple and reliable, can adjust the motion characteristics of the door actuation of the equipment, and has better adaptability.
The above object of the present invention is achieved by the following technical solutions:
a cabin door actuating mechanism comprises a guide rod, a slide block, a guide rod support rod, a crank support rod, a support seat, a slide block rotating shaft, a crank rotating shaft and a guide rod rotating shaft, wherein the guide rod and a cabin door are rigidly connected into a whole, or the guide rod and the cabin door are in transmission connection through a gear pair, one end of each of the guide rod support rod and the crank support rod is fixed on the support seat, when the guide rod and the cabin door are in transmission connection through the gear pair, the axle center of one gear of the gear pair is concentric with the guide rod rotating shaft,
the relative positions of the guide rod, the slide block, the guide rod supporting rod, the crank supporting rod, the slide block rotating shaft, the crank rotating shaft and the guide rod rotating shaft satisfy the following relations:
S＞L，R≥4S/π，
wherein: l is the distance between the rotating axes of the guide rod and the guide rod rotating shaft and the rotating axes of the crank and the crank support rod;
s is the distance between the rotating axes of the crank and the crank support rod and the rotating axes of the slide block and the slide block rotating shaft;
r is the bending radius of the arc-shaped guide rod;
m is the farthest distance between the slide block on the guide rod and the rotating shaft center of the guide rod and the rotating shaft of the guide rod.
Wherein, the guide rod supporting rod and the crank supporting rod are fixed on the support in parallel. Therefore, the parallel fixation leads the fixed support arrangement of the whole cabin door actuating mechanism to be more compact, the occupied space to be smaller and the stress to be better.
The cabin door actuating system has few components, and is simple and reliable; by adjusting the relative sizes of R, L, M and S of the four-bar mechanism and the connection relationship between the guide rod and the cabin door, the motion characteristic of the equipment cabin door can be adjusted, and the four-bar mechanism has better adaptability.

Detailed Description
For a clearer understanding of the objects, technical solutions and advantages of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic view of the hatch door actuating mechanism of the present invention, as shown in the drawing, in this embodiment, the main body of the hatch door actuating mechanism of the present invention is a hinge four-bar linkage mechanism, which includes a guide rod 1, a slider 2, a guide rod support rod 3, a crank 4, a crank support rod 5, a support 6, a slider rotating shaft 7, a crank rotating shaft 8 and a guide rod rotating shaft 9, the guide rod 1 and the hatch door 10 are rigidly connected into a whole, one end of each of the guide rod support rod 3 and the crank support rod 5 is fixed on the support 6, the slider 2 slides on the guide rod 1 under the action of the crank 4, the rotating axes of the guide rod 1 and the guide rod rotating shaft 9 are O, the rotating axes of the crank 4 and the crank support rod 5 are a, the rotating axes of the slider 2 and the slider rotating shaft 7 are B, the farthest from the O point on the guide rod 1 is a C point, the distance between the axis O and the axis a is L, the distance between the axis a and the axis B is S, the distance between the axis O and the C point is M, the distance between the support rod 3.
On the other hand, the guide rod 1 and the door 10 may also be in transmission connection through a gear pair 11, in which case one gear axis of the gear pair 11 is concentric with the guide rod rotation shaft 9, and the other gear is rigidly connected with the door 10, as illustrated in fig. 2.
In the cabin door actuating mechanism, the relative positions of a guide rod 1, a slide block 2, a guide rod support rod 3, a crank 4, a crank support rod 5, a slide block rotating shaft 7, a crank rotating shaft 8 and a guide rod rotating shaft 9 satisfy the following relations: s is more than L, R is more than or equal to 4S/pi,
α at minimum, the door is at maximum opening and α at maximum, the door is in the closed position.
Because the adopted guide rod 1 is an arc rod with the bending radius R, and the relative positions of the guide rod 1, the slide block 2, the guide rod support rod 3, the crank 4, the crank support rod 5, the slide block rotating shaft 7, the crank rotating shaft 8 and the guide rod rotating shaft 9 meet the relationship, the actuation process has a sine characteristic, and the cabin door 10 is opened at the minimum speed in the opening process and then gradually accelerated; the hatch door 10 starts to act at the maximum speed in the closing process, and then gradually decelerates to the minimum speed to close the hatch door 10, so that the opening and the closing are soft, and the impact is small. The velocity law of the movement of the door 10 is determined by the relative sizes of R, L, M and S. The relative position relationship between the hatch 10 and the fixed end of the support 6 can be adjusted by adjusting the size of N. In addition, the guide rod strut and the crank strut are preferably fixed on the support 6 in parallel, so that the parallel fixation leads to the fixed support arrangement of the whole cabin door actuating mechanism to be more compact, the occupied space to be smaller and the stress to be better.
When the cabin door 10 is rigidly connected with the guide rod 1, the motion center of the cabin door is the axis of the guide rod rotating shaft 9; when the hatch door 10 is in transmission connection with the guide rod 1 through the gear pair 11, the movement center of the hatch door is the axis of the gear which is not concentric with the guide rod rotating shaft 9 in the gear pair 11, and one of the two fixing modes is selected according to different requirements of the opening and closing paths of the hatch door.
Fig. 2 is a schematic view showing an application example of the door actuating mechanism according to the present invention, as shown in fig. 2, in the present embodiment, the door actuating mechanism includes the guide rod 1, the slider 2, the guide rod support 3, the crank 4, the crank support 5, the support 6, the slider rotating shaft 7, the crank rotating shaft 8, and the guide rod rotating shaft 9 as described above with reference to fig. 1, and is different from the structure described with reference to fig. 1 in that the guide rod 1 is drivingly connected to the door 10 through the gear pair 11, specifically, an external gear (or rack) of the gear pair 11 is concentric with the guide rod rotating shaft 9 and is rigidly connected to the guide rod rotating shaft 9, and an internal gear (or rack) is rigidly connected to the door 10.
