[0031] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0032] Reference Figure 1 and Figure 2 The embodiment of the present invention provides a device for automatically leveling two unequal planes of an aircraft cabin, comprising a fixed frame 1, a rotating shaft 2, a linear motion mechanism, a sliding sleeve 3 and an elastic buffer mechanism. The automatic leveling of this embodiment realizes the automatic leveling process of two unequal planes of an aircraft cabin by integrating components such as the rotating shaft 2, the linear motion mechanism, the sliding sleeve 3 and the elastic buffer mechanism. Compared with the traditional manual leveling method, this automated device greatly improves the accuracy and efficiency of the operation.

[0033] The rotating shaft 2, the linear moving mechanism, the sliding sleeve 3 and the elastic buffer mechanism are all installed on the fixed frame 1. The rotating shaft 2 has a fixed shaft section 21 and a transverse shaft section 22 that are connected to each other. The fixed shaft section 21 can be fixedly connected to an external device so that the rotating shaft 2 is fixedly arranged relative to the reference platform 4, and the transverse shaft section 22 is rotatably connected to one side of the fixed frame 1. The design of the rotating shaft 2 allows its fixed shaft section 21 to be fixedly connected to an external device, while the transverse shaft section 22 is rotatably connected to one side of the fixed frame 1. This structure enables the device to adapt to cabin planes of different angles and positions, thereby enhancing the flexibility and scope of application of the device.

[0034] The sleeve 3 is arranged at the bottom of the fixed frame 1, and the sleeve 3 is vertically slidably connected to the fixed frame 1. The linear moving mechanism is arranged on the fixed frame 1, and the linear moving mechanism can be extended and retracted in the vertical direction. The elastic buffer mechanism is connected to the linear moving mechanism, and when the linear moving mechanism is extended, the elastic buffer mechanism can push the sleeve 3 to move away from the fixed frame 1. The linear moving mechanism can be extended and retracted in the vertical direction, and cooperate with the elastic buffer mechanism to achieve precise control of the sleeve 3. When the linear moving mechanism is extended, the elastic buffer mechanism can provide a stable thrust to push the sleeve 3 to move away from the fixed frame, thereby ensuring the smoothness and reliability of the leveling process. The introduction of the elastic buffer mechanism can not only provide the necessary thrust during the leveling process, but also play a buffering role when contacting the cabin plane.

[0035] During operation, the fixed shaft section 21 is fixed to control the extension of the linear moving mechanism. The linear moving mechanism drives the point or line at the bottom of the sleeve 3 to contact the reference platform 4 through the elastic buffer mechanism. The sleeve 3 continues to move downward, and the rotating shaft 2 rotates until the bottom of the sleeve 3 is completely in contact with the reference platform 4, so that the plane at the bottom of the sleeve 3 and the plane where the reference platform 4 is located are leveled. The entire device has a compact structure and is easy to operate. The integrated design greatly simplifies the leveling process. At the same time, automated operation also significantly improves work efficiency and reduces labor costs.

[0036] The device for automatic leveling of two unequal planes of an aircraft cabin body in the above-mentioned embodiment realizes automatic leveling of two unequal planes of an aircraft cabin body through ingenious structural design, and has the advantages of high precision, good flexibility, strong stability, good buffering protection effect and easy operation, and is of great significance for improving work efficiency and quality in the process of aircraft manufacturing and maintenance.

[0037] According to a further optimized solution, the elastic buffer mechanism includes a fixed platform 5 and an elastic member 6. The fixed platform 5 is arranged at the bottom of the fixed frame 1, the top of the fixed platform 5 is connected to the linear motion mechanism, a first step structure is arranged on the top of the fixed platform 5, the elastic member 6 is sleeved on the fixed platform 5, and the top of the elastic member 6 abuts against the first step structure, and the bottom of the elastic member 6 abuts against the sleeve 3. This design enables the elastic member 6 to provide an effective buffering effect when the linear motion mechanism extends to push the sleeve to move, reducing the vibration and noise caused by direct impact, thereby enhancing the stability and reliability of the entire device. The buffering effect of the elastic member 6 not only helps to push the sleeve 3, but also provides a certain amount of idle travel after the sleeve 3 contacts the reference platform 4.

[0038] Further optimization scheme, the bottom of the sleeve 3 is a plane, the sleeve 3 has a first cavity 31 and a second cavity 32, the first cavity 31 is arranged above the second cavity 32, the first cavity 31 and the second cavity 32 are coaxially arranged and interconnected, the first cavity 31 and the second cavity 32 are provided with a second step structure at the junction, the bottom end of the elastic member 6 abuts against the second step structure, the fixed platform 5 can pass through the cavity in the middle of the second step structure, and the second cavity 32 is used to place the carrying member. In the above embodiment, the bottom of the sleeve 3 is designed to be a plane, which ensures uniform contact with the surface of the aircraft cabin and improves the accuracy and stability of leveling. The setting of the step structure enables the elastic member 6 to distribute pressure more evenly during compression and recovery, and improves the stability and consistency of the buffering effect. The first cavity 31 and the second cavity 32 are coaxially arranged and interconnected. This structural design not only reduces the weight of the sleeve 3, but also enables the fixed platform to pass through the connection position of the first cavity 31 and the second cavity 32, which plays a role of giving way to prevent interference. The carrying member can select structures such as reference blocks.

[0039] According to the further optimized solution, the linear moving mechanism includes a linear motor 7, which is fixedly connected to the fixed frame 1, and the output shaft of the linear motor 7 is fixedly connected to the top of the fixed platform 5. Since the linear motor has a simple mechanical structure and does not have easily worn parts such as gears and lead screws in traditional mechanical transmission, it has the advantages of high speed, high precision, low noise and high reliability. At the same time, the linear motor has no mechanical contact during the movement, and the transmission force is generated in the air gap. There is no other friction except the linear motor guide rail, so the motion inertia can be reduced, and the response speed and sensitivity of the device for automatic leveling of two non-planar surfaces of the aircraft cabin in this embodiment can be improved.

[0040] According to a further optimized solution, the fixed shaft section 21 and the transverse shaft section 22 are arranged at an angle of 5 to 45 degrees.

[0041] In a further optimized solution, a sliding sleeve 8 is sleeved on the transverse shaft section 22, the sliding sleeve 8 is rotatably connected to the transverse shaft section 22, and the fixed frame 1 is fixedly connected to the sliding sleeve 8. The sliding sleeve 8 enables the transverse shaft section 22 and the fixed frame 1 to rotate smoothly.

[0042] In a further optimized solution, a screw 9 is installed on the top of the fixed frame 1, and the screw 9 is fixedly connected to the sliding sleeve 8, and the axis of the sliding sleeve 8 intersects with the axis of the screw 9. The screw 9 plays a role in fixing the fixed frame 1 and the sliding sleeve 8.

[0043] In a further optimized solution, a limit block 10 is provided at the joint of the transverse shaft section 22 and the fixed shaft section 21, and the limit block 10 has a vertical plane, and the vertical plane is in contact with the fixed frame 1. The limit block 10 prevents the fixed frame 1 from colliding with the rotating shaft 2, and increases the lateral support force of the rotating shaft 2 on the fixed frame 1.

[0044] According to a further optimization scheme, a section of the fixed shaft section 21 away from the transverse shaft section 22 is fixedly connected with a fixing member 11, and the fixing member 11 is used to connect the fixed shaft section 21 with other devices, and the other devices are used to keep the rotating shaft 2 relatively fixed.

[0045] According to a further optimized solution, the elastic member 6 includes a spring.

[0048] 2. The design of the rotating shaft 2 allows its fixed shaft section 21 to be fixedly connected to an external device, while the transverse shaft section 22 is rotationally connected to one side of the fixed frame 1. This structure enables the device to adapt to cabin planes of different angles and positions, thereby enhancing the flexibility and applicability of the device.

[0049] 3. The introduction of the elastic buffer mechanism can not only provide the necessary thrust during the leveling process, but also play a buffering role when contacting the cabin plane, so that the ground of the sliding sleeve 3 slowly overlaps with the reference platform 4.
