It has the ability to search, detect, track and locate targets with high precision and can be used in various fields. The gimbal carried by drones not only has the function of shooting, but also can autonomously identify and track ground or air targets through advanced tracking algorithms.

[0003] The processor in the optoelectronic device is a core component responsible for processing images and data. After running for a long time or when the operating environment temperature is high, the processor may generate a lot of heat.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 8 As shown, the present invention provides an optoelectronic tracking gimbal, including an unmanned aerial vehicle 1, wherein an optoelectronic gimbal assembly 2 and an airflow guide assembly 3 are fixedly connected to the bottom of the unmanned aerial vehicle 1, an adjustment assembly 4 is slidably connected to the bottom of the optoelectronic gimbal assembly 2, and a wind control assembly 5 and a closing assembly 6 are slidably connected inside the airflow guide assembly 3;

[0032] The optoelectronic pan-tilt assembly 2 includes a pan-tilt base 21 , a three-axis rotating bracket 22 is installed at the bottom of the pan-tilt base 21 , an optoelectronic device 23 is installed at the lower end of the three-axis rotating bracket 22 , and an arc-shaped protrusion 24 is fixedly connected to the upper end of the three-axis rotating bracket 22 .

[0033] The above scheme is adopted: a part of the airflow of the rotor of the drone 1 is diverted through the deflector 31, so that the airflow is blown out from the lower air outlet 32 ​​at the bottom of the deflector 31 and blown to the optoelectronic device 23 to cool it. When the three-axis rotating bracket 22 rotates, the arc-shaped protrusion 24 will squeeze the limiting plate 43 on one side, so that the support frame 41 drives the limiting slide bar 53 to move in the direction of rotation of the three-axis rotating bracket 22. As the rotation amplitude of the three-axis rotating bracket 22 increases, the limiting slide bar 53 driven by the support frame 41 gradually moves to squeeze the elastic limiting rotating rod 63, and then squeezes the first sliding member 61 to move, so that the first sliding member 61 pushes the baffle inside the lower air outlet 32 ​​to close through the limiting protrusion 64; when The three-axis rotating bracket 22 rotates to face the air deflector 31 on one side, and the air deflector 31 facing the arc-shaped protrusion 24 will be flipped to a vertical state due to the limiting slide bar 53. At the same time, the baffle inside the lower air outlet 32 ​​is squeezed and closed by the limiting protrusion 64, so that no airflow is blown out on the side facing the arc-shaped protrusion 24. At the same time, the limiting slide bar 53 on the other side is pulled to the top of the first slide groove 34, so that the lower air outlet 32 ​​and the side air outlet 33 on the back of the arc-shaped protrusion 24 are both in an open state; the three-axis rotating bracket 22 and the optoelectronic device 23 are always kept in a state of being cooled by the airflow, and at the same time, the airflow is prevented from blowing directly to the lens of the optoelectronic device 23, causing damage to the lens of the optoelectronic device 23.

[0034] like Figures 3 to 6 As shown, the airflow guide assembly 3 includes a pair of guide covers 31, each of which has a lower air outlet 32 ​​at the bottom, a side air outlet 33 at one end of the guide covers 31 close to each other, a first slide groove 34 and a second slide groove 35 on the inner side of the guide covers 31, and a diverter plate 36 is linearly distributed inside the guide covers 31.

[0035] The above scheme is adopted: by setting up the airflow guide component 3, the downward airflow generated by the rotor of the drone 1 can be partially guided by the air guide cover 31 to the optoelectronic pan-tilt assembly 2, so as to cool the optoelectronic pan-tilt assembly 2. The lower air outlet 32 ​​and the side air outlet 33 opened on the air guide cover 31 can guide the airflow diverted from the air guide cover 31 to the three-axis rotating bracket 22 and the optoelectronic device 23. The setting of the first slide groove 34 and the second slide groove 35 is convenient for controlling the sliding direction of the elastic slide bar 52 and the limit slide bar 53. The diverter plate 36 arranged inside the air guide cover 31 can disperse the airflow guided by the air guide cover 31 downward to avoid collision between them inside the air guide cover 31 and cause airflow turbulence.

[0036] like Figures 3 to 6As shown, the air deflector 31 is fixedly connected to the UAV 1, the air deflector 31 is bent, and the air deflector 31 matches the shape of the bottom side of the UAV 1, the air deflector 31 is distributed on both sides of the three-axis rotating bracket 22, and the three-axis rotating bracket 22 is located in the middle of the center line of a pair of air deflectors 31, the lower air outlet 32 ​​and the side air outlet 33 are both rotatably connected with baffles, and the baffles are turned over and opened to face the optoelectronic device 23, the first slide groove 34 is located on the lower side of the second slide groove 35, the first slide groove 34 is in a gradually ascending step shape, and the slide grooves between the steps of the first slide groove 34 are in an arc shape, and the diverter plate 36 is in conflict with the UAV 1.

[0037] The above scheme is adopted: the airflow generated by the rotor of the drone 1 during flight is similar to a downwardly expanding frustum. By setting the air guide cover 31 to a bent shape and matching the shape of the bottom side of the drone 1, the part of the airflow of the rotor close to the fuselage of the drone 1 can be guided so that it can blow toward the optoelectronic gimbal assembly 2 to cool the optoelectronic gimbal assembly 2. The air guide cover 31 is set on both sides of the three-axis rotating bracket 22, so that the air guide cover 31 can cool the three-axis rotating bracket 22 from both sides to avoid blowing air to the three-axis rotating bracket 22 from one side, causing the three-axis rotating bracket 22 to become unstable. Baffles are set inside the lower air outlet 32 ​​and the side air outlet 33 to guide the airflow to the optoelectronic device 23. The first slide groove 34 is set to a gradually rising step shape, so that after the limit slide bar 53 slides inside the first slide groove 34, it can gradually drive the wind shield 51 to flip to a horizontal or vertical state.

[0038] like Figures 2 to 6 As shown, the adjustment assembly 4 includes a support frame 41, with limited sliding grooves 42 at both ends of the support frame 41, a pair of limit plates 43 installed in the middle of the support frame 41, and two pairs of first spring pieces 44 fixedly connected in the middle of the support frame 41;

[0039] The limiting plates 43 are distributed on both sides of the three-axis rotating bracket 22 in a mirror image, the limiting plates 43 are in conflict with the arc-shaped protrusions 24 , and the first elastic sheet 44 is fixedly connected to the drone 1 .

[0040] The above scheme is adopted: by setting the adjustment component 4, the adjustment component 4 can be squeezed by rotating the three-axis rotating bracket 22, thereby adjusting the opening degree of the air deflector 31, and limiting slide grooves 42 are opened at both ends of the support frame 41, so that the support frame 41 can drive the limiting slide bar 53 to slide in the first slide groove 34 through the limiting slide groove 42, and the setting of a pair of limiting plates 43 can be achieved by setting the limiting plates 43 on both sides of the three-axis rotating bracket 22, so that the arc-shaped protrusion 24 squeezes the limiting plates 43, and then the limiting plates 43 drive the limiting slide bar 53 to move through the support frame 41 and the limiting slide groove 42, so that the lower air outlet 32 ​​facing the arc-shaped protrusion 24 is closed.

[0041] like Figure 6 , Figure 7 and Figure 8 As shown, the wind control component 5 includes a wind shield 51, an elastic slide bar 52 is rotatably connected inside the wind shield 51, and a limit slide bar 53 is slidably connected inside the wind shield 51; the wind shield 51 is located inside the air deflector 31 and is slidably connected to the air deflector 31, the wind shield 51 is in conflict with the diverter plate 36, the elastic slide bar 52 is slidably connected inside the second slide groove 35 and is elastically connected to the air deflector 31, the limit slide bar 53 is slidably connected inside the first slide groove 34, and both ends of the limit slide bar 53 are slidably connected inside the limit slide groove 42.

[0042] The above scheme is adopted: by setting the wind control component 5, the opening and closing states of the lower air outlet 32 ​​and the side air outlet 33 can be adjusted. The design of the wind shield 51 is used to limit the airflow derived from the air guide cover 31. When the wind shield 51 is vertical, the air guide cover 31 is blocked and closed by the wind shield 51, so that the airflow cannot enter the air guide cover 31. When the wind shield 51 is tilted, the airflow will be guided to the lower air outlet 32, so that the airflow is blown out from the lower air outlet 32 ​​after the flow rate is limited. When the wind shield 51 is horizontal, the wind shield 51 will squeeze the elastic limit rotating rod 63 at the same time to make The baffle at the side air outlet 33 is pushed open, allowing the airflow at the air guide cover 31 to be blown out from the lower air outlet 32 ​​and the side air outlet 33 without restriction, so as to cool the three-axis rotating bracket 22 and the optoelectronic device 23. The elastic slide bar 52 and the limit slide bar 53 are provided to control the inclination degree of the wind shield 51. At the same time, the limit slide bar 53 will squeeze the elastic limit rotating rod 63 when the wind shield 51 is vertical, so that the first sliding member 61 is pushed by the elastic limit rotating rod 63, and then the baffle inside the lower air outlet 32 ​​is squeezed by the limit protrusion 64 to close the baffle.

[0043] like Figure 7 and Figure 8 As shown, the closing component 6 includes a first sliding member 61 and a second sliding member 62, the end of the first sliding member 61 away from the second sliding member 62 is hinged with an elastic limiting rotating rod 63, the end of the second sliding member 62 facing the wind shield 51 is provided with a limiting protrusion 64, the end of the first sliding member 61 close to the second sliding member 62 is fixedly connected to the second elastic piece 65, the side of the second sliding member 62 away from the wind shield 51 is fixedly connected to the extrusion protrusion 66, and the end of the second sliding member 62 away from the first sliding member 61 is fixedly connected to the third elastic piece 67.

[0044] By adopting the above scheme: by setting the closing component 6, the closing state of the inner baffles of the lower air outlet 32 ​​and the side air outlet 33 can be controlled by the first sliding member 61 and the second sliding member 62. The elastic limiting rotating rod 63 hinged at one end of the first sliding member 61 can make the elastic limiting rotating rod 63 push the first sliding member 61 to slide after the limiting sliding rod 53 squeezes the elastic limiting rotating rod 63, and then the first sliding member 61 drives the limiting protrusion 64 to move and squeeze the baffle inside the lower air outlet 32, so as to close the lower air outlet 32. The setting of the limiting protrusion 64 can squeeze the lower air outlet 3 2 is flipped to close the lower air outlet 32. By setting the second spring piece 65, the elastic limiting rotating rod 63 is released from being squeezed and reset by the limiting sliding rod 53, and the second spring piece 65 can push the first sliding member 61 to reset, so that the baffle inside the lower air outlet 32 ​​is unlocked and opened. The squeezing protrusion 66 arranged on the side of the second sliding member 62 can push the baffle inside the side air outlet 33 to open after the second sliding member 62 is squeezed by the wind shield plate 51, so that the airflow blows from the side air outlet 33 to the three-axis rotating bracket 22, so as to cool the three-axis rotating bracket 22.

[0045] like Figure 7 and Figure 8 As shown, the first sliding member 61 and the second sliding member 62 are both slidably connected to the air deflector 31, the first sliding member 61 is located on the outside of the air deflector 31, the elastic limiting rotating rod 63 is located at the upper end of the first sliding member 61 and conflicts with the limiting sliding rod 53, the elastic limiting rotating rod 63 is located at the end of the first sliding member 61 away from the second elastic sheet 65, the limiting protrusion 64 is located at the bottom of the air deflector 31, the limiting protrusion 64 conflicts with the baffle inside the lower air outlet 32, the second sliding member 62 is located inside the air deflector 31, the second sliding member 62 conflicts with the wind shield 51, the extrusion protrusion 66 conflicts with the baffle inside the side air outlet 33, and the second elastic sheet 65 and the third elastic sheet 67 are both fixedly connected to the air deflector 31.

[0046] The above scheme is adopted: by setting the first sliding member 61 and the second sliding member 62, the opening or closing of the side air outlet 33 of the lower air outlet 32 ​​is controlled by the position of the limiting slide bar 53, and the first sliding member 61 is set on the outside of the air deflector 31, so that the elastic limiting rotating rod 63 at the upper end of the first sliding member 61 will conflict with the limiting slide bar 53 to avoid blocking the movement of the wind shield 51, and the limiting protrusion 64 is set as an inclined surface at the abutment between the limiting protrusion 64 and the internal baffle of the lower air outlet 32, so that the limiting protrusion 64 will not get stuck when pushing the baffle, and can provide a certain support for the baffle when the baffle is opened, and the second sliding member 62 is set inside the air deflector 31, and the wind shield 51 can squeeze the second sliding member 62 to move the second sliding member 62, and simultaneously squeeze the baffle inside the side air outlet 33 through the squeezing protrusion 66 to open the side air outlet 33.

[0047] like Figure 2 and Figure 8As shown, when the arc-shaped protrusion 24 does not interfere with the limiting plate 43, the support frame 41 is kept centered by the thrust of the first elastic sheet 44, and at the same time, the support frame 41 pulls the limiting slide bar 53 to remain centered, so that the limiting slide bar 53 is located in the middle of the first slide groove 34, so that the wind shield 51 is tilted toward the lower air outlet 32, and the first sliding member 61 is driven by the thrust of the second elastic sheet 65 to drive the limiting protrusion 64 to move, thereby releasing the interference with the internal baffle of the lower air outlet 32, so that the baffle inside the lower air outlet 32 ​​is flipped downward and opened.

[0048] The above scheme is adopted: when the arc-shaped protrusion 24 does not conflict with the limit plate 43, the support frame 41 pulls the limit slide bar 53 through the limit slide groove 42 to keep it centered, so that the limit slide bar 53 is located in the middle of the first slide groove 34, so that the wind shield plate 51 is tilted toward the lower air outlet 32. At this time, the baffle inside the lower air outlet 32 ​​is in an open state, and the airflow guided out from the rotor of the drone 1 by the air guide cover 31 is blown toward the optoelectronic device 23 to cool the optoelectronic device 23.

[0049] The working principle and use process of the present invention are as follows: after the drone 1 flies into the air, a part of the airflow of the rotor of the drone 1 will be guided by the air deflector 31, so that the airflow is blown out from the lower air outlet 32 ​​at the bottom of the air deflector 31 to the optoelectronic device 23. When the optoelectronic pan-tilt assembly 2 is in operation, the orientation of the optoelectronic pan-tilt assembly 2 needs to be adjusted. When the three-axis rotating bracket 22 rotates, the arc-shaped protrusion 24 will squeeze the limiting plate 43 on one side, so that the support frame 41 drives the limiting slide bar 53 to move in the direction of rotation of the three-axis rotating bracket 22 through the limiting slide groove 42. As the rotation amplitude of the three-axis rotating bracket 22 increases, the moving distance of the support frame 41 will gradually increase, and the limiting slide bar 53 will gradually squeeze the elastic limiting rotating rod 63, so that the elastic limiting rotating rod 63 flips downward, and then squeezes the first sliding member 61 to move, so that the first sliding member 61 gradually pushes the baffle inside the lower air outlet 32 ​​to close through the limiting protrusion 64;

[0050] When the three-axis rotating bracket 22 rotates to face the air guide 31 on one side, the air guide 31 facing the arc-shaped protrusion 24 will be flipped to a vertical state due to the limiting slide bar 53, and at the same time, the baffle inside the lower air outlet 32 ​​is squeezed and closed by the limiting protrusion 64, so that no air is blown out on the side facing the arc-shaped protrusion 24, and at the same time, the limiting slide bar 53 on the other side is pulled to the top of the first slide groove 34, so that the wind shield 51 pushes the baffle inside the side air outlet 33 to open through the second sliding member 62 and the squeezing protrusion 66, so that the air can be blown out through the side air outlet 33, so that the lower air outlet 32 ​​and the side air outlet 33 on the back of the arc-shaped protrusion 24 are both in an open state, so as to cool down the three-axis rotating bracket 22 and the optoelectronic device 23, so that the three-axis rotating bracket 22 and the optoelectronic device 23 can always be cooled by the airflow to avoid the three-axis rotating bracket 22 and the optoelectronic device 23 from being overheated.
