Description

Technical Field

[0001] The utility model belongs to the technical field of IMUs, and in particular relates to a double-sided MEMS IMUs single-axis rotation adjustment device. Background Art

[0002] The double-sided MEMS IMUs single-axis rotation adjustment device is a device with a specific design for adjusting and controlling the rotation angle of a double-sided MEMS (Micro-Electro-Mechanical Systems) inertial measurement unit (IMUs) mounted on a bracket relative to a reference direction. This device usually includes a bracket and a double-sided MEMS IMU. The bracket has an adjustable mechanism that allows the user or system operator to adjust the direction of the IMUs in a single-axis rotation manner. By rotating the bracket, the angle of the IMUs relative to the reference direction can be changed to adapt to different application requirements or environmental conditions.

[0003] During use, existing double-sided MEMS IMUs single-axis rotation adjustment devices may not meet the requirements in some application scenarios that require the IMUs to rotate around their own axis, such as some robot attitude control or aircraft attitude stability control. Utility Model Content

[0004] The purpose of the utility model is to provide a double-sided MEMS IMUs single-axis rotation adjustment device. By setting a single-axis rotation mechanism, it solves the problem that some application scenarios that require the IMUs to rotate around their own axes may not meet the requirements, such as some robot attitude control or aircraft attitude stability control.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a double-sided MEMS IMUs single-axis rotation adjustment device, comprising a turntable, on which a single-axis rotation mechanism and a limit mechanism are arranged;

[0007] The single-axis rotating mechanism includes a revolution component and a rotation component. The revolution component includes a motor arranged below the turntable. A motor sleeve is fixedly sleeved on the outer wall of the motor. A rotating shaft 1 passes through the turntable. The bottom end of the rotating shaft 1 is fixedly connected to the output shaft of the motor. A support plate is rotatably installed on the top end of the rotating shaft 1.

[0008] Furthermore, the self-rotating component includes a second rotating shaft passing through the support plate, a rotating groove is opened in the support plate, a clamping ring is fixedly sleeved on the outer wall of the second rotating shaft, and the outer wall of the clamping ring extends into the rotating groove and is rotatably connected to the rotating groove.

[0009] Furthermore, a pulley 1 is fixedly mounted on the rotating shaft 1 and the rotating shaft 2 respectively, and a belt 1 is wound around the two pulleys 1.

[0010] Furthermore, a rotating shaft 3 is rotatably mounted on the top of the support plate, and a pulley 2 is fixedly sleeved on the rotating shaft 3 and the rotating shaft 2 respectively.

[0011] Furthermore, a belt 2 is wound around the two pulleys 2, and MEMSIMUS are respectively fixedly mounted on the top ends of the two rotating shafts 3.

[0012] Furthermore, a circular ring 1 is fixedly installed at the bottom end of the turntable, a circular ring 2 is rotatably installed below the turntable, the end of the motor sleeve is fixedly connected to the circular ring 2, and a rotating groove 2 is respectively opened on the inner wall of the circular ring 1 and the outer wall of the circular ring 2, and a plurality of steel balls are slidably installed on the side where the two rotating grooves 2 are close to each other.

[0013] Furthermore, the limiting mechanism includes a support ring fixedly installed at the bottom end of the two circular rings, a T-shaped rotating groove is opened at the top of the support ring, and a plurality of rotating rods are fixedly installed at the bottom end of the steel ball, and the ends of the plurality of rotating rods extend into the T-shaped rotating groove and are slidably connected to the T-shaped rotating groove.

[0014] The utility model has the following beneficial effects:

[0015] 1. By setting the revolution assembly, when the device is installed, the motor on the motor sleeve can be started. The motor drives the turntable on the ring one to rotate under the action of the steel ball in the groove two through the shaft one, so that the device revolves. When the device revolves, the support ring at the bottom of the ring two provides necessary support for the turntable through the T-shaped groove and the rotating rod, thereby ensuring the stability of the device, allowing the user or system operator to adjust the direction of the IMUs relative to the reference direction. The direction of the device can be adjusted as needed to adapt to different application scenarios or environmental conditions. It can be measured in different directions, thereby enhancing its ability to adapt to different working scenarios. This adaptability is particularly important for applications that require attitude measurement or navigation in multiple directions. Direction calibration can be performed to ensure the accuracy of the measurement results. By adjusting the direction of the IMUs, it can be aligned with the reference direction, thereby reducing measurement errors;

[0016] 2. By setting up a self-rotation component, when the motor drives the device to revolve, it will also drive the second shaft to rotate through the pulley 1 and belt 1 on the first shaft, and the second shaft will drive the third shaft to rotate through the pulley 2 and belt 2, thereby driving the two MEMSIMUS to rotate, so that the device can rotate around its own axis, thereby enhancing the comprehensiveness of attitude measurement. The device can obtain more complex attitude information, including parameters such as pitch, roll and yaw, rather than being limited to measurement in a single direction, which can help the device more accurately capture the motion state of the target object. Rotating on its own axis, the device can measure at different angles and directions, thereby improving the accuracy and reliability of the measurement data, and can improve the control ability of the device, so that it can better adapt to the needs in a dynamic environment. For example, in applications such as robot control or aircraft attitude stability control, the self-rotation component can help the device adjust the attitude more accurately to maintain stability.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
