Description

Technical Field

[0001] The utility model mainly relates to the technical field of photoelectric pods, and in particular to a non-load-bearing photoelectric pod structure of a rolling axis motor. Background Art

[0002] At present, the optoelectronic pod products on the market mainly include two-axis optoelectronic pods and three-axis optoelectronic pods, which are mainly equipped with visible light cameras, infrared thermal imaging and laser guidance equipment, etc. The optoelectronic pods need to be installed on drones for use. The two-axis optoelectronic pods only have a heading axis and a pitch axis. Therefore, when the two-axis optoelectronic pod adjusts the heading of the drone to produce a roll angle, the camera in the pod will also produce an angle, causing the picture seen by the rear end to have a tilt angle. After adding a third axis roll axis to the optoelectronic pod, the roll angle of the camera can be corrected. However, the roll axis of most existing three-axis optoelectronic pods on the market needs to bear the weight of the roll axis motor to bear the pod and the pitch axis, which to a certain extent limits the quality of the camera and other detection equipment that can be carried in the optoelectronic pod, and also affects the service life of the motor.

[0003] The current shortcomings of the three-axis optoelectronic pod structure are: 1. The three-axis optoelectronic pod structure causes the roll-axis motor to bear the weight of the pitch axis and the pod, resulting in the weight of the equipment carried by the pod being limited by the bending strength that the motor can withstand; 2. The three-axis optoelectronic pod structure causes the roll-axis motor to bear the weight of the pitch axis and the pod, resulting in the motor main shaft being subjected to the bending moment caused by the pod's gravity, affecting the service life of the motor; 3. The roll-axis structure of the three-axis optoelectronic pod is mostly directly driven by the motor, which is not conducive to the miniaturization of the drive motor. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the above-mentioned problems, the utility model needs to provide a roll axis motor non-load-bearing optoelectronic pod structure, which can improve the load-bearing capacity and strain capacity of the optoelectronic pod.

[0006] (II) Technical solution

[0007] In view of the above technical problems, the utility model provides a roll-axis motor non-load-bearing optoelectronic pod structure, including a main frame, on which a first outer frame and a second outer frame are rotatably installed, the first outer frame and the second outer frame are ring-shaped, and two inner frames are symmetrically rotatably installed on the inner axis of the ring, a gimbal camera and gimbal accessories are fixedly installed between the two inner frames, a roll-axis motor is fixedly installed between the two inner frames, the output shaft of the roll-axis motor is fixedly connected to a pinion, an arc-shaped rack is fixedly installed on the first outer frame, and the pinion is meshed with the arc-shaped rack.

[0008] Furthermore, the main frame is an inverted U-shape, annular grooves are provided at both ends of the inverted U-shape, and a top groove is provided at the top of the U-shape; both sides of the outer diameter of the first outer frame and the second outer frame are fixedly connected to the connecting ring by screws.

[0009] Furthermore, the connecting ring is rotatably connected to the annular groove, and a small ball bearing is provided between the connecting ring and the annular groove.

[0010] Furthermore, the inner frame is fixedly connected to a large ball bearing, and the large ball bearing is arranged on the first outer frame and the second outer frame.

[0011] Furthermore, each of the two inner frames is fixedly connected to a supporting side plate by means of screws, and the gimbal camera and the gimbal accessories are fixedly mounted on the supporting side plates.

[0012] Furthermore, a small fixing seat is fixedly mounted on the supporting side plate, and the roll axis motor is fixedly mounted on the small fixing seat by fasteners.

[0013] Compared with the prior art, the utility model has the following beneficial effects: 1. By changing the force position of the roll axis, the weight of the equipment carried by the optoelectronic pod is no longer limited by the bending moment strength that the roll axis motor can withstand, thereby greatly improving the carrying weight of the optoelectronic pod equipment; 2. By adjusting the structure, the roll axis motor and the pinion are installed on the inner frame, and the arc rack is installed on the first outer frame, thereby increasing the transmission ratio, so that when the roll axis motor adjusts the roll angle, it only needs to overcome the gravity and inertia force of the equipment in the optoelectronic pod to shorten the adjustment time and improve the reaction speed.
