[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
[0032] Please refer to Figures 1-2This utility model provides an attitude sensor testing platform, including: a guide rail 400, which is set perpendicular to the height direction; a load slide 200, which is slidably connected to the guide rail 400; a three-axis electric rotary table 100, which is set on the load slide 200 and is used to mount the attitude sensor so as to drive the attitude sensor to rotate in any direction to test the rotational kinetic energy; and a driving component 300, which is set on the load slide 200 and is used to drive the load slide 200 to slide along the guide rail 400 so as to test the positional kinetic energy of the attitude sensor.
[0033] In summary, the attitude sensor testing platform integrates three-dimensional displacement and rotation testing. The three-axis electric rotary table 100 can perform rotation testing on the attitude sensor, and the drive component 300 can drive the load slide 200 to move along the guide rail 400 to achieve displacement testing of the attitude sensor. After the attitude sensor is rotated by the three-axis electric rotary table 100, the displacement of the attitude sensor in any direction can be tested. Therefore, the entire attitude sensor testing platform can perform multi-dimensional testing simultaneously or perform different aspects of testing on different objects at the same time.
[0034] Among them, the testing of various kinetic energies includes displacement kinetic energy testing in three-dimensional space and rotational kinetic energy testing. Displacement kinetic energy can be obtained through mass and velocity, while rotational kinetic energy can be obtained through angular velocity and moment of inertia. The structure of rotational motion and displacement motion can generate complex motion conditions to simulate the actual environment. Subsequently, the testing of multiple attitude sensors can be completed by acquiring the attitude changes of attitude sensors.
[0035] In a further embodiment, the three-axis electric rotary table 100 includes: a mounting frame 120 disposed on a load slide 200; and three electric rotating components 110 disposed on the mounting frame 120, the rotation axes of the three electric rotating components 110 being perpendicular to each other, to test the rotational kinetic energy of the attitude sensor in any direction.
[0036] In this scheme, three orthogonal axial electric rotating components 110 can be combined to form rotation in any direction, enabling the part under test to complete rotational testing of the X / Y / Z axes and their composite directions in three-dimensional space. This overcomes the limitations of single-axis testing. The rigid connection design between the mounting bracket 120 and the load slide 200 enhances the mechanical support strength while ensuring rotational freedom, effectively suppressing vibration deviation during the test. Each electric rotating component 110 can be independently adjusted with an angle accuracy of 0.1°. With the help of the servo control system, it can perform single-axis precision rotation and realize three-axis linkage composite motion simulation.
[0037] In a further embodiment, the attitude sensor test platform also includes a frame 600 and a first mounting component 500, with the guide rail 400 connected to the frame 600 via the first mounting component 500.
[0038] The frame 600 adopts an integral welded frame structure, ensuring that the flatness error of the guide rail 400 installation is controlled within 0.05mm / m, effectively eliminating measurement errors caused by foundation deformation during testing. The standardized interface design of the first mounting component 500 allows the attitude sensor testing platform to support quick replacement of guide rails 400 of different specifications (length 1-5m optional), meeting the testing needs of various scenarios in laboratories and industrial fields.
[0039] In a further embodiment, the frame 600 includes: a base 610; a pair of first support members 620 disposed on the base 610 and extending in the height direction; a connector 630, with its two ends respectively connected to one of the pair of first support members 620 and disposed parallel to the first support member 620; and at least one pair of first mounting members 500, with at least one first mounting member 500 disposed at the top end of the pair of first support members 620.
[0040] In this design, the foot 610 stabilizes the entire attitude sensor test platform on the ground and also reduces vibration. The first support 620 provides support and can also mount the first mounting piece 500 to support the guide rail 400. A pair of first support pieces 620 can stabilize the guide rail 400 and reduce swaying. The connector 630 connects the pair of first support pieces 620 and can effectively prevent the first support pieces 620 from swaying and tilting.
[0041] Specifically, the main structure of the frame 600 can be supported by multiple aluminum profiles, such as the connector 630 and the first support 620, which can be assembled from aluminum profiles of different specifications.
[0042] In a further embodiment, the attitude sensor test platform also includes a control box 700 and a drive cable 800; the control box 700 is mounted on the frame 600, and the drive cable 800 is electrically connected to the control box 700, the drive unit 300, and the three-axis electric rotary table 100.
[0043] In a further embodiment, the rack 600 further includes: a second support member 640, which is disposed on the connector 630 and parallel to the first support member 620; three first mounting members 500 are provided, with one first mounting member 500 respectively disposed at the top of each first support member 620 and each second support member 640; and a control box 700 is disposed on the connector 630 and connected to the second support member 640.
[0044] In a further embodiment, the rack 600 also includes a second mounting member 650, which is disposed on the connector 630 and connected to the second support member 640.
[0045] Please refer to Figures 3-4In a further embodiment, the control box 700 includes: a box body 710, mounted on a frame 600; a box door 720, movably connected to the box body 710 and forming a cavity within the box body 710; a display and control terminal 740, mounted within the cavity, for preset parameters; and an observation window 730, mounted on the box door 720, for observing the display and control terminal 740 when the box door 720 is closed.
[0046] In a further embodiment, the control box 700 also includes a plurality of power supplies 750, which are disposed within the cavity, and each power supply 750 has a voltage between 5-25V. Figure 4 The three power supplies shown in the image, from top to bottom, are 5V, 12V, and 24V, used to power different types of power-consuming components.
[0047] The method of using this utility model is as follows:
[0048] First, the test object is fixed on the three-axis electric rotary table 100 and connected to the control box 700. Then, test parameters are set on the display and control terminal 740 according to the test requirements.
