[0024] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0025] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0027] Reference Figure 1-4 The present embodiment provides a multi-angle gimbal camera bracket, including a camera body 2 installed at the bottom of a drone body 1 and a positioning table 3 connected to the bottom surface of the drone body 1, an electric-controlled cross universal joint 6 is provided on the bottom surface of the positioning table 3, a connecting arm 7 is provided on one side of the electric-controlled cross universal joint 6, a mounting disc 8 is provided at the bottom end of the connecting arm 7, and L-shaped clamping arms 9 are symmetrically provided on both sides of the mounting disc 8.

[0028] Furthermore, a positioning hoop 10 is engaged on the outer surface of the L-shaped clamping arm 9, and a positioning bolt 11 is provided at the end of the positioning hoop 10. The camera body 2 is located between adjacent L-shaped clamping arms 9. When the entire device is actually used, it is mainly connected to the bottom surface of the drone body 1 through the positioning cone 3 screws or bolts.

[0029] When installing the entire gimbal, the back of the camera body 2 is against the surface of the mounting disk 8, and the surface of the camera body 2 is clamped by adjusting the distance between the two L-shaped clamping arms 9 to abut against the surface of the camera body 2. In order to increase the clamping stability between adjacent L-shaped clamping arms, secondary positioning and fixing are performed by a positioning hoop 10. The end of the positioning hoop 10 is positioned by a positioning bolt 11 to maintain the clamping force between the L-shaped clamping arm 9 and the surface of the camera body 2 to prevent the camera body 2 from falling off or shaking. In addition, since the positioning hoop 10 indirectly positions the camera body 2 through the L-shaped clamping arm 9, a certain gap is provided between the positioning hoop 10 and the camera body 2, so that air can be diverted and heat can be dissipated during the use of the camera body 2, avoiding the traditional direct contact with the camera body 2, which causes the problem of temperature rise.

[0030] Furthermore, the pan / tilt of the entire device is electrically driven by a servo motor 4 and an electrically controlled cross universal joint 6. The specific structure is that a servo motor 4 is vertically embedded in the positioning table 3, and a reducer 5 is connected to the output shaft of the servo motor 4. The bottom end of the reducer 5 is threadedly connected to the top surface of the electrically controlled cross universal joint 6. The reducer 5 is located inside the positioning table 3 and is movably engaged with the inner wall of the positioning table 3. The top surface of the electrically controlled cross universal joint 6 is against the bottom surface of the positioning table 3. The servo motor 4 drives the electrically controlled universal joint, the mounting disk 8, the camera body 2, etc. connected at the bottom to rotate and move as a whole through the reducer 5 to realize the detection of left and right viewing angles. The servo motor 4 controls the 360-degree detection of the left and right viewing angles. The electrically controlled cross universal joint 6 can control the maximum adjustment change of the pitch angle of the camera body 2, so that the detection range of the entire camera body 2 is wider, blind spots are avoided, and the freedom and flexibility of detection are improved, thereby significantly improving the shooting effect and the diversity of data collection. Specific embodiment 2:

[0032] The only difference between this embodiment and the first embodiment is that limiting grooves 14 are provided on both sides of the mounting disk 8, and limiting springs 13 are provided inside the limiting grooves 14. The ends of the limiting springs 13 are connected to the ends of the L-shaped clamping arms 9. The L-shaped clamping arms 9 cooperate with the limiting springs 13 to adjust the distance between adjacent L-shaped clamping arms 9, so as to adapt to camera bodies 2 of different sizes.

[0033] Furthermore, a positioning groove 12 is provided on the outer surface of the L-shaped clamping arm, and the surface of the positioning groove 12 is interference fit with the center position of the positioning hoop 10. The positioning hoop 10 is symmetrically distributed on both sides of the surface of the mounting disk 8, so that the connection between the positioning hoop 10 and the L-shaped clamping arm is stable to prevent sliding, and no other mounting structure is required. The positioning is directly performed by the surface engagement to maintain the stability of the connection and prevent falling off. At the same time, the edges of the outer surface of the L-shaped clamping arm 9 are all rounded, and the surface of the L-shaped clamping arm 9 is coated with a silicone coating to increase the stability of clamping the camera body 2. By setting the silicone coating, scratches and damages when in contact with the surface of the camera body 2 can be prevented, thereby protecting the camera body 2.

[0034] At the same time, the front vertical center line of the positioning truncated table 3, the front vertical center line of the electronically controlled universal joint, and the front vertical center line of the mounting disk 8 coincide with each other. Specific embodiment three:

[0036] The difference between this embodiment and the first or second embodiment is that the electrically controlled cross universal joint 6 comprises:

[0037] Cross axis: The cross axis is the core component of the universal joint, which allows flexible changes in angles in two perpendicular directions.

[0038] Needle roller bearing: Needle roller bearing is used to support the cross shaft, reduce friction and wear during its movement, and improve transmission efficiency.

[0039] Electronic control device: The electronic control device usually includes a servo motor 4, a reducer 5 and related control circuits. The servo motor 4 provides power, and the reducer 5 reduces the speed and increases the torque to accurately control the movement of the cross shaft.

[0040] Mounting interface: The electronically controlled cross universal joint 6 is usually equipped with a mounting interface, such as a bolt hole or a flange, so as to be connected to the drone body 1 or other equipment.

[0041] The use of the electronically controlled cross universal joint 6 mainly includes the following steps:

[0042] Installation: Fix the electronically controlled cross universal joint 6 to the drone body 1 or other equipment that needs to adjust the angle through its installation interface, and ensure that it is firmly installed to reduce the influence of vibration and looseness on the transmission accuracy.

[0043] Connect the electronic control system: Connect the electronic control device of the electronically controlled cross universal joint 6 to the control system of the UAV or a dedicated electronic control module, and set corresponding control parameters such as motion range, speed, acceleration, etc. according to specific application requirements.

[0044] Angle adjustment: The control system sends instructions to the electronic control device to drive the servo motor 4 to work. The servo motor 4 transmits power to the cross shaft through the reducer 5 to achieve angle changes. Through precise control algorithms and sensor feedback, the cross shaft can be accurately positioned at any angle.

[0045] Monitoring and adjustment: During use, the status of the electronically controlled cross universal joint 6 can be monitored in real time through the control system of the drone or dedicated monitoring software, and the control parameters can be adjusted or manual intervention can be performed at any time according to actual needs to meet different shooting or work needs. Specific embodiment four:

[0047] This embodiment provides a drone, which includes a drone body 1 and the multi-angle gimbal camera bracket described in any one of Embodiments 1 to 3.

[0048] In summary, the present application controls the camera body 2 connected at the bottom to perform multi-angle movement adjustment through the servo motor 4 and the external electric cross universal joint 6, so that the detection range of the entire camera body 2 is wider, the detection blind spots are avoided, and the freedom and flexibility of detection are improved, thereby significantly improving the shooting effect and the diversity of data collection;

[0049] At the same time, the camera body 2 is clamped and positioned by the mounting disc 8 in cooperation with the L-shaped clamping arm 9, so that the camera body 2 is stably clamped between the mounting discs 8, reducing the risk of image blur or equipment damage caused by vibration during flight, and there is a certain gap between the positioning clamp 10 and the camera body 2, which can be used for air diversion and heat dissipation during the use of the camera body 2, avoiding the traditional direct contact with the camera body 2, which causes the problem of temperature increase.
