Technical Field

[0001] This utility model relates to the field of gyroscope testing technology, specifically a mobile phone gyroscope testing platform. Background Technology

[0002] A mobile phone gyroscope, also known as an angular velocity sensor, works on the principle of conservation of angular momentum. Simply put, when an object rotates in a certain direction, it will have an angular momentum vector perpendicular to the axis of rotation. Often, it is necessary to test the mobile phone gyroscope at multiple angles to test whether the gyroscope is functioning properly.

[0003] According to the announcement number CN217845212U, entitled "A Planar Switching Platform Device for Gyroscope Testing, including a base plate," research and analysis revealed that although the planar switching platform device has advantages such as being convenient for staff to use and adjust testing functions, it also has the following disadvantages to a certain extent.

[0004] For example, when adjusting the angle of a mobile phone gyroscope testing platform, staff need to manually adjust the angle of the plane switching platform device, which is cumbersome, has low sensitivity, and requires a lot of work, making it inconvenient for staff to conduct tests. In order to solve the above technical problems, it is necessary to design a mobile phone gyroscope testing platform. Utility Model Content

Detailed Implementation

[0019] Please see Figures 1-3 A mobile phone gyroscope testing platform includes a support plate 4. A servo motor 1 is fixedly mounted on the top of the support plate 4. A connecting seat 5 is fixedly sleeved on the rotating shaft of the servo motor 1. A linkage mechanism 2 is movably mounted on the surface of the connecting seat 5. An upper platform 3 is mounted on the surface of the linkage mechanism 2. An adjustment mechanism 6 is mounted on the surface of the upper platform 3. The adjustment mechanism 6 includes a base plate 7. The base plate 7 is welded to the surface of the upper platform 3. A return spring 8 and a balance rod 9 are fixedly connected to the surface of the base plate 7. A bearing rod 10 is fixedly connected to the surface of the return spring 8. A limit plate 11 is provided through the surface of the bearing rod 10. A support plate 12 is welded to the surface of the limit plate 11. A spring telescopic rod 13 is welded to the surface of the support plate 12. One end of the spring telescopic rod 13 is inserted into the inner wall of the limit plate 11.

[0020] Please see Figure 1 The linkage mechanism 2 includes a locking sleeve 14, a connecting rod 15 is fixedly connected to the opposite side of the locking sleeve 14, and a fixing plate 16 is fixedly connected to the surface of the upper platform 3. By setting the fixing plate 16, a support point is provided for the upper platform 3 and the connecting rod 15, so that the connecting rod 15 can bear the pressure. A connecting shaft 17 is movably connected between the surface of the fixing plate 16 and the connecting seat 5 and the locking sleeve 14. A connecting groove 18 is opened on the surface of the connecting seat 5.

[0021] Please see Figure 1 The connecting grooves 18 are arranged at equal intervals. By setting the connecting grooves 18, the supported object is stably supported, and the usability of the connecting shaft 17 is improved. The connecting shaft 17 is welded to the fixing plate 16. One end of the bottom connecting shaft 17 passes through the connecting groove 18 and is snapped into it.

[0022] Please see Figure 1 There are several servo motors 1, and each servo motor 1 is composed of two sets working together. By setting the servo motors 1, the connecting seat 5 is an actuator that controls the rotation of the connecting seat 5, which can ensure the safe and effective operation of the connecting seat 5.

[0023] Please see Figure 3One end of the balance bar 9 passes through the support bar 10 and is threaded with a nut 19. By setting the nut 19, the position of the support bar 10 can be limited, which can improve the overall quality of the support bar 10 structure. One side of the nut 19 is in contact with the surface of the support bar 10, and the support bar 10 is movably sleeved on the surface of the balance bar 9.

[0024] Please see Figure 2 and Figure 3 The surface of the spring telescopic rod 13 is welded with a lever. By setting the lever, the friction between the user and the spring telescopic rod 13 is increased, thereby improving the usability of the spring telescopic rod 13. The spring telescopic rod 13 and the inner wall of the bearing rod 10 are movably connected.

[0025] In use, the limiting plate 11 is moved to change the support stress point, pushing the bearing rod 10 to slide along the surface of the balance rod 9 in a transverse linear track, stretching the return spring 8. The mobile phone gyroscope to be tested is placed on the surface of the upper plate 3. When the return spring 8 is stretched to its limit, the limiting plate 11 loses external tension under elastic action and starts to move in the opposite direction, making tight contact with the mobile phone gyroscope. The bearing rod 10 moves closer to each other as the limiting plate 11 moves. By rotating the nut 19 and connecting it to the balance rod 9 with the thread, the balance rod 9 moves closer to the bottom plate 7 and contacts the bearing rod 10, stabilizing the bearing rod 10 and making the limiting plate 11 less likely to move, thereby improving the stability of the mobile phone gyroscope. Pulling the lever causes one end of the spring extension rod 13 to disengage from the limiting plate 11 and the bearing rod. The inner wall of the 10, the lateral movement limiting plate 11 is disengaged from the inside of the bearing rod 10, so that the bearing rod 10 and the limiting plate 11 can be disassembled and assembled, so that the limiting plate 11 can be flexibly adjusted according to the actual needs of the placed object. The output shaft of the servo motor 1 on one side is activated to operate the connecting seat 5 to rotate. The connecting seat 5 drives the locking sleeve 14 and the connecting rod 15 connected to it to move down or up through the connecting shaft 17. The connecting rod 15 drives one side of the upper platform 3 to tilt and rotate synchronously through the fixing plate 16. The upper platform 3 drives the mobile phone gyroscope to rotate through the limiting plate 11. When the mobile phone rotates, the rotor contained inside the mobile phone gyroscope will maintain its original rotation direction and speed, so as to sense the rotation state of the mobile phone by measuring the change of the angular velocity of the rotor.

[0026] In summary, this mobile phone gyroscope testing platform, through the cooperation of the servo motor 1, linkage mechanism 2, upper platform 3, support plate 4, connecting seat 5, and adjustment mechanism 6, solves the problem of reducing the workload of staff and avoiding the phenomenon of mobile phone gyroscope slippage during angle adjustment.
