[0002] The aircraft includes arms and a power unit, which includes a motor and a rotor. The motor is mounted on the arm and its output shaft is connected to the rotor. Testing the power unit can ensure the performance, safety, and reliability of the aircraft.

[0003] Current power sleeve testing equipment includes a test bench and a power sleeve and an incoming flow fan fixed on the test bench. In the test of the power sleeve, the angle between the rotor and the incoming flow and the incoming flow velocity are fixed values ​​that cannot be adjusted, and cannot simulate the actual flight conditions. Furthermore, the test bench cannot be loaded according to the flight profile. The profile can only be simplified and strengthened before loading is performed on the test bench. As a result, the load on the power sleeve in the test bench cannot accurately reproduce the load on the power sleeve during actual flight, and the test results cannot completely correspond to the actual flight results. Utility Model Content

[0004] In view of this, the present invention provides a power sleeve testing device to solve the problem of inaccurate test results caused by the inability to adjust the angle between the power sleeve and the incoming flow fan.

[0006] Beneficial effects: The tilt angle adjustment mechanism can adjust the tilt angle of the upper platform relative to the lower platform, thereby adjusting the tilt angle of the power sleeve relative to the incoming flow direction. At the same time, the incoming flow size can be adjusted by adjusting the speed of the incoming flow fan, simulating the changes in tilt angle and incoming flow size of the power sleeve during actual flight. This can simulate the actual flight state, ensuring more accurate test results and effectively solving the problem of inaccurate test results caused by the inability to adjust the angle between the power sleeve and the incoming flow fan.

[0007] In one optional embodiment, the tilt adjustment mechanism includes: a first hinge structure connected to the upper platform and the lower platform; and a displacement driving mechanism, one end of which is hinged to the lower platform and the other end of which is hinged to the upper platform, wherein the displacement driving mechanism and the first hinge structure are spaced apart.

[0008] Beneficial effects: By changing its own displacement through the displacement drive mechanism, the upper platform rotates around the hinge point of the first hinge structure, thereby changing the angle between the power sleeve and the incoming flow direction, thus simulating the tilt angle of the power sleeve during actual flight. The rotation of the upper platform can be achieved by controlling only the displacement drive mechanism, which is simple to control and allows for precise height control of angle changes.

[0009] In one alternative embodiment, the tilt adjustment mechanism includes two displacement driving mechanisms, which are spaced apart. One end of each displacement driving mechanism is hinged to the lower platform and the other end is hinged to the upper platform.

[0011] Beneficial effects: By using the same host computer to simultaneously and in real-time control the displacement of the displacement drive mechanism, the rotational speed of the power sleeve, and the rotational speed of the incoming flow fan, the control is synchronized. This allows for real-time adjustment of the angle between the power sleeve and the incoming flow, as well as changes in the magnitude of the incoming flow. It simulates the tilt angle of the power sleeve and changes in the magnitude of the incoming flow during actual flight, achieving real-time control of the angle between the power sleeve and the incoming flow, and the speed of the incoming flow. This improves the response speed and effectively solves the problem of delay between incoming flow control and power sleeve rotational speed control caused by using different host computers to control the rotational speed of the power sleeve and the incoming flow fan in existing technologies.

[0012] In one optional embodiment, the displacement driving mechanism includes two displacement driving components arranged side by side, with the arrangement direction of the two displacement driving components perpendicular to the arrangement direction of the displacement driving mechanism and the first hinge structure.

[0013] Beneficial effect: The synchronous movement of the two displacement drive components enables smooth movement of the upper platform, thereby improving the accuracy of the test.

[0014] In one alternative implementation, the displacement driving component is a hydraulic cylinder, a pneumatic cylinder, a linear motor, a ball screw mechanism, a rack and pinion mechanism, or a cam mechanism.

[0015] Beneficial effects: Hydraulic cylinders have advantages such as precise control and smooth movement.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0042] According to an embodiment of the present invention, a power sleeve testing device is provided, comprising: a lower platform 1, an upper platform 2, an incoming flow fan 10, and an angle adjustment mechanism. The upper platform 2 is disposed above the lower platform 1 and is used to install the power sleeve 9. The incoming flow fan 10 is disposed on one side of the lower platform 1. The angle adjustment mechanism is disposed between the upper platform 2 and the lower platform 1 and is used to adjust the angle of inclination of the power sleeve 9 relative to the incoming flow direction of the incoming flow fan 10.

[0043] The power sleeve testing device of this embodiment can adjust the tilt angle of the upper platform 2 relative to the lower platform 1 through the tilt angle adjustment mechanism, thereby adjusting the tilt angle of the power sleeve 9 relative to the incoming flow direction. At the same time, the speed of the incoming flow fan 10 can be adjusted to adjust the incoming flow size, simulating the changes in tilt angle and incoming flow size of the power sleeve 9 during actual flight. This can simulate the actual flight state, ensure more accurate test results, and effectively solve the problem of inaccurate test results caused by the inability to adjust the angle between the power sleeve and the incoming flow fan.

[0044] In one embodiment, the tilt adjustment mechanism includes a first hinge structure 3 and a displacement drive mechanism 4. The first hinge structure 3 is connected to the upper platform 2 and the lower platform 1. One end of the displacement drive mechanism 4 is hinged to the lower platform 1 and the other end is hinged to the upper platform 2. The displacement drive mechanism 4 and the first hinge structure 3 are spaced apart. By changing its own displacement, the displacement drive mechanism 4 causes the upper platform 2 to rotate around the hinge point of the first hinge structure 3, thereby changing the angle between the power sleeve 9 and the incoming flow direction, thus simulating the tilt angle of the power sleeve 9 during actual flight. The rotation of the upper platform 2 can be achieved by controlling only the displacement drive mechanism 4, which is simple to control and allows for precise control of the angle change.

[0045] It should be noted that the rotation axis of the upper platform 2 is perpendicular to the incoming flow direction, and the displacement direction of the displacement drive mechanism 4 is perpendicular to the rotation axis of the upper platform 2 and the incoming flow direction.

[0046] Understandably, in another embodiment, the tilt adjustment mechanism includes two displacement drive mechanisms 4, which are spaced apart. One end of each displacement drive mechanism 4 is hinged to the lower platform 1, and the other end is hinged to the upper platform 2. The tilt angle of the power sleeve 9 can also be changed by adjusting the displacements of the two displacement drive mechanisms 4.

[0047] In one embodiment, such as Figure 4As shown, the power sleeve testing device also includes a host computer 5, which is electrically connected to the power sleeve 9, the incoming flow fan 10, and the displacement drive mechanism 4. The host computer 5 is used to control the rotational speed of the power sleeve 9, the rotational speed of the incoming flow fan 10, and the displacement of the displacement drive mechanism 4. The host computer 5 simulates the rotational speed change of the aircraft in actual flight conditions by controlling the rotational speed change of the power sleeve 9, simulates the incoming flow speed change or airspeed change of the aircraft in actual flight conditions by controlling the rotational speed change of the incoming flow fan 10, and causes the power sleeve 9 to tilt by controlling the displacement change of the displacement drive mechanism 4, thereby changing the angle between the power sleeve 9 and the incoming flow direction and simulating the tilt angle of the power sleeve 9 in actual flight conditions. That is, the tilt angle of the power sleeve 9 in actual flight conditions is simulated by controlling the displacement change of the displacement drive mechanism 4. Using the same host computer 5 to simultaneously and in real-time control the displacement of the displacement drive mechanism 4, the rotational speed of the power sleeve 9, and the rotational speed of the incoming flow fan 10, the control is synchronized. This allows for real-time adjustment of the angle between the power sleeve 9 and the incoming flow, as well as changes in the magnitude of the incoming flow. This simulates the tilt angle of the power sleeve 9 and changes in the magnitude of the incoming flow during actual flight, achieving real-time control of the angle between the power sleeve 9 and the incoming flow, and the speed of the incoming flow. This improves the response speed and effectively solves the problem of delay between incoming flow control and power sleeve rotational speed control caused by using different host computers to control the rotational speed of the power sleeve and the incoming flow fan in existing technologies.

[0048] In one embodiment, such as Figures 1 to 3 As shown, the displacement driving mechanism 4 includes two displacement driving components 401, which are arranged side by side. The arrangement direction of the two displacement driving components 401 is perpendicular to the arrangement direction of the displacement driving mechanism 4 and the first hinge structure 3. The synchronous movement of the two displacement driving components 401 achieves smooth movement of the upper platform 2, thereby improving testing accuracy. The host computer 5 sends control signals to the displacement driving components 401, and the displacement driving components 401 adjust their own displacement according to the control signals.

[0049] In one embodiment, the displacement driving component 401 is a hydraulic cylinder, which has advantages such as precise control and smooth movement.

[0050] It is understood that, in another embodiment, the displacement drive component 401 is a cylinder, a linear motor, a ball screw mechanism, a gear and rack mechanism, or a cam mechanism, etc.

A second hinge seat 602 is fixed on the upper platform 2, and the other end of the second hinge seat 602 is connected to the displacement driving component 401 via a lower hinge shaft. The combination of the hinge seat and the hinge shaft ensures smooth and reliable rotation of the upper platform 2 when the displacement driving component 401 undergoes displacement changes. It also facilitates installation and disassembly, making maintenance and replacement more convenient.

[0052] In one embodiment, the first hinge structure 3 includes an upper hinge seat 301, a hinge shaft, and a lower hinge seat 302. The upper hinge seat 301 is fixed on the upper platform 2, and the lower hinge seat 302 is fixed on the lower platform 1. The hinge shaft is connected to the upper hinge seat 301 and the lower hinge seat 302. The first hinge structure 3 has a simple structure, is easy to install and disassemble, and is more convenient for maintenance and replacement.

[0053] Furthermore, there are two first hinge structures 3, which are arranged side by side to further ensure that the movement of the upper platform 2 is smoother and more stable.

[0054] In one embodiment, such as Figures 1 to 3 As shown, the power sleeve testing device also includes a support arm 7. One end of the support arm 7 is fixed to the upper platform 2, and the other end of the support arm 7 extends out of the upper platform 2 and is used to install the power sleeve 9. By using the support arm 7 to simulate the arm of an aircraft, the installation structure of the power sleeve 9 is made closer to the installation structure of the aircraft itself, making the test results closer to the actual flight results and improving the accuracy of the test.

[0055] Furthermore, the power sleeve 9 is bolted to the support arm 7, the support arm 7 is bolted to the upper platform 2, the upper hinge seat 301 is bolted to the upper platform 2, the lower hinge seat 302 is bolted to the lower platform 1, the first hinge seat 601 is bolted to the lower platform 1, and the second hinge seat 602 is bolted to the upper platform 2. The bolted fixing method facilitates installation and disassembly.

[0056] Specifically, the outrigger 7 includes a main boom 701 and two side booms 702. The two side booms 702 are located on both sides of the main boom 701. One end of the main boom 701 and one end of the side boom 702 are fixed to the upper platform 2. The other end of the main boom 701 is fixed with a power sleeve 9, and the other end of the side boom 702 is fixed to the main boom 701.

[0057] It should be noted that the power unit 9 includes a motor 901 and a rotor 902. The motor 901 is fixed on the support arm 7, and the output shaft of the motor 901 is connected to the rotor 902.

[0058] It is understandable that, in another embodiment, the support arm may also be replaced by the arm of an aircraft.

[0059] In one embodiment, such as Figure 1 As shown, the power sleeve testing device also includes a base 8, on which the lower platform 1 is fixed. The base 8 provides support for the lower platform 1 and the components thereon, resulting in more stable and reliable support. The lower platform 1 is fixed to the base 8 with bolts.

[0060] Furthermore, the base 8 is made of materials such as cement.
