[0002] A "Dual-Axis Gimbal Module" generally refers to a device used to control motion and positioning, capable of rotating freely in two perpendicular directions (usually horizontally and vertically). It is commonly found in vehicle or missile stabilization and targeting systems. In automobiles, this module is typically used to stabilize and automatically adjust camera and radar systems, enabling 360-degree environmental perception for autonomous driving systems and ensuring that sensors remain stable throughout the vehicle's journey. With the advancement of automotive technology, the number of integrated device modules is increasing. Therefore, Dual-Axis Gimbal Modules need to be reduced in weight and size to meet current market demands. Utility Model Content

[0015] Furthermore, an electrical connector mounting bracket and an electrical connector are provided on the base to facilitate connection between the mechanism and the carrier system.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0017] The utility model is composed of three components: a base, an outer frame and a simulated load module, and is driven to rotate by two groups of resolver spindle modules and a motor spindle module, that is, the rotation is driven by the motor spindle module, and then the resolver spindle module provides feedback on the angle and speed of the spindle. The two are used in conjunction to ensure that the rotation situation can be perceived in real time. On this basis, a circuit board is built in, and the feedback data is transmitted in real time through the provided terminal. After installation and use, the signal can be transmitted to the control system in real time. When it deviates from the predetermined position, the control system can correct the output of the motor, thereby accurately controlling the resolver position.

It can achieve precise control in high dynamic environments and can be widely used in fast response and high-precision scenarios.

[0018] The present invention is also provided with a gear disc end locking structure and a push rod end locking structure, wherein the push rod locking module generally adopts a mechanical push rod to fix the simulated load module in a specific position to prevent it from moving or rotating, and uses mechanical or hydraulic principles to push the push rod to provide a strong locking force to avoid accidental loosening and affecting the accuracy in the non-working state, wherein the gear disc end locking structure cooperates with multiple teeth on the gear disc, and engages with the gear disc by moving the locking component (such as a pawl) to prevent the gear disc from continuing to rotate or move. In scenarios requiring multi-gear adjustment, precise angle or position control can be achieved, that is, the gear disc locking can be used for angle control and fixation to ensure the accurate aiming angle before firing and prevent any position offset. When the two are used in combination, that is, in mechanical equipment requiring multi-angle adjustment, the gear disc locking is used for angle adjustment, and the push rod locking is used for strong fixation in the final position, thereby ensuring the stability and safety of the system.

[0019] The utility model also arranges shielding plates and shielding pads on the inner frame resolver spindle module and the inner frame motor spindle module and the outer frame resolver spindle module and the outer frame motor spindle module, which can effectively prevent electromagnetic interference, protect the spindle module and its internal electrical and mechanical components from external interference and damage, and greatly improve the equipment accuracy.
