[0002] In automobiles, three-axis indexing modules are mainly used to enhance vehicle functionality and automation levels, especially in systems such as autonomous driving, in-vehicle cameras, and radar. They can improve automation and intelligence, enabling flexible and precise angle adjustments and enhancing the intelligence level of in-vehicle systems. For autonomous driving and safety systems, three-axis adjustment helps vehicles better perceive their surroundings and adapt to diverse road conditions and driving scenarios. As automobiles develop, more and more modules are integrated, placing certain demands on the overall module size and requiring miniaturization. Furthermore, compared to dual-axis modules, three-axis indexing modules require higher precision due to the need to achieve three-dimensional rotation. Utility Model Content

[0037] Preferably, both the outer frame 2 and the base 1 are provided with counterweights 20. Specific Implementation

[0038] This device is installed in a vehicle and connected to the vehicle's control system. When the vehicle is in operation, it rotates through three sets of resolver spindle modules and a motor spindle module. The motor spindle module drives the rotation, and the resolver spindle module provides feedback on the spindle's angle and speed. The two work together to ensure real-time sensing of the rotation. A circuit board is built in, and the feedback data is transmitted in real time through designated terminals. This allows for real-time signal transmission to the control system. When the device deviates from the predetermined position, the control system can correct the motor output, thereby precisely controlling the resolver position.

[0039] The system includes a gear-end locking structure 15 and a push rod-end locking structure 14. The push rod-end locking module 14 typically uses a mechanical push rod 12 to fix the simulated load module 4 in a specific position, preventing it from moving or rotating. The push rod 12 is driven by mechanical or hydraulic principles to provide a strong locking force, preventing accidental loosening that could affect accuracy when not in operation. The gear-end locking structure 15 works with multiple teeth on the gear 13, engaging with the gear 13 via a moving locking component (e.g., a ratchet) to prevent the gear 13 from continuing to rotate or move. In scenarios requiring multi-position adjustments, it enables precise angle or position control. In other words, the gear-end locking structure 15 can be used for angle control and fixation, ensuring accurate aiming angle before launch and preventing any positional deviation. When used together, i.e., in mechanical equipment requiring multi-angle adjustments, the gear 13 locking is used for angle adjustment, while the push rod 12 locking is used for strong fixation at the final position, thereby ensuring the stability and safety of the system.

[0040] During operation, a counterweight 20 is installed to effectively balance the center of gravity of the equipment, making it more stable and reducing imbalance caused by eccentricity. At the same time, it can effectively counteract the vibration caused by imbalance when the spindle rotates, reduce the noise of the equipment, extend its service life, and improve the overall accuracy.

[0041] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific embodiments of the present invention are limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
