[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5This utility model provides a technical solution: a detachable camera gimbal structure for a surveying drone, including a drone body 4, a gimbal frame 1 at the bottom rear of the drone body 4, a camera mounting shell 2 at the rear of the gimbal frame 1, and a camera 3 inside the camera mounting shell 2. The overall assembly of the detachable camera gimbal structure is based on the drone body 4, and through the sequential connection of various components, a complete camera gimbal system is formed, providing basic support for the installation, fixation and subsequent operation of the camera.

[0024] The main body of the drone, 4, can take off by providing lift through its wings, which is existing technology and will not be explained here.

[0025] Please see Figure 2 The gimbal frame 1 includes a gimbal base 11 fixedly connected to the rear side of the bottom of the drone body 4. A vertical support rod 12 is fixedly connected to the middle of the bottom of the gimbal base 11. An axial support rod 13 is rotatably connected to the bottom of the vertical support rod 12. A rotating support column 14 is fixedly connected to the rear end of the axial support rod 13. The right end of the rotating support column 14 is rotatably connected to the left end of the camera mounting shell 2.

[0026] The gimbal 1 is able to rotate at multiple angles by connecting the vertical support rod 12 and the axial support rod 13, thus providing structural support for the camera 3 to adjust its shooting angle.

[0027] Please see Figure 2 - Figure 3 The camera mounting housing 2 includes a fixed bottom housing 21 rotatably connected to the right end of the rotating support column 14. The fixed bottom housing 21 has fixing holes 22 in the middle of the upper and lower sides of the rear end, and a fixing sleeve 23 is provided on the rear side of the fixed bottom housing 21.

[0028] The fixed base 21 is rotatably connected to the right end of the rotating support column 14 of the gimbal 1, so that the fixed base 21 can rotate relative to the rotating support column 14 to adjust the angle. The fixing hole 22 provides a connection point for the fixed sleeve 23. The fixed sleeve 23 is set on the rear side of the fixed base 21. Through cooperation with the fixed base 21, it together forms a space to accommodate and fix the shooting camera 3.

[0029] Please see Figure 3 The fixed housing 23 includes a camera cover 232. The front end of the camera cover 232 is fixedly connected to the middle of the upper and lower sides with a fixing pin 231. The outer surface of the fixing pin 231 is provided with an arc-shaped locking groove, and the fixing pin 231 can enter the interior of the fixing hole 22.

[0030] The camera cover 232 is engaged with the fixing hole 22 of the fixing base shell 21 by fixing pins 231 on the upper and lower front sides. When it is necessary to fix the shooting camera 3, the fixing pin 231 can be inserted into the fixing hole 22. The arc-shaped locking groove on its outer surface can lock with the corresponding structure in the fixing hole 22, thereby connecting the camera cover 232 with the fixing base shell 21 and realizing the wrapping and fixing of the shooting camera 3.

[0031] Please see Figure 4 - Figure 5 The fixed base shell 21 includes a base shell body 211 rotatably connected to the right end of the rotating support column 14 at its left end. Inside the base shell body 211, there are three fixed insertion holes 216 communicating with the fixed holes 22. Fixed balls 215 are movably arranged inside the fixed insertion holes 216. One-third of the fixed balls 215 can enter the inside of the fixed holes 22 through the fixed insertion holes 216. The top of the three fixed balls 215 is provided with a pressing fixed block 214. The pressing fixed block 214 is slidably connected to the inside of the base shell body 211. The bottom end of the pressing fixed block 214 is an arc surface on the side near the fixed hole 22. The top of the pressing fixed block 214 is fixedly connected to an inverted conical guide drive block 213. The top of the guide drive block 213 is fixedly connected to a fixed spring 212. The top of the fixed spring 212 is fixedly connected to the inside of the base shell body 211.

[0032] Under the elastic force of the fixed spring 212, the guide drive block 213 pushes the pressing fixed block 214 to slide downward. The arc surface of the pressing fixed block 214 squeezes the fixed ball 215, causing the fixed ball 215 to be inserted into the locking groove of the fixing pin 231. When the fixing pin 231 is inserted into the fixing hole 22, the top of the fixing pin 231 will push the pressing fixed block 214 forward by squeezing the fixing ball 215, providing space for entry. After the fixing pin 231 is fully inserted, the fixing pin 231 is firmly locked in the fixing hole 22 through the cooperation of the fixing ball 215 and the locking groove, realizing the stable fixation of the shooting camera 3. When the fixing pin 231 is not unlocked and pulled out, the contact between the locking groove and the fixing ball 215 will drive the fixing ball 215 to move synchronously towards the fixing pin 231. With the downward pressure of the pressing fixed block 214 and the fixed spring 212, an increasingly tight effect is formed.

[0033] Please see Figure 4 - Figure 5 The bottom shell body 211 has an unlocking knob 217 rotatably connected to the middle of the front end. The unlocking knob 217 has an unlocking plate 218 fixedly connected to the rear end. The unlocking plate 218 has unlocking posts 219 on both the upper and lower sides. The outer surface of the unlocking post 219 is slidably connected to the inside of the bottom shell body 211. The end of the unlocking post 219 away from the unlocking plate 218 is in contact with the inclined surface of the guide drive block 213.

[0034] When the camera needs to be disassembled, turn the unlocking knob 217 to rotate the unlocking plate 218. The elliptical contour of the unlocking plate 218 can push the unlocking pins 219 on the upper and lower sides to slide within the bottom shell body 211. The end of the unlocking pin 219 presses against the inclined surface of the guide drive block 213, causing the guide drive block 213 to compress the fixing spring 212, which in turn drives the lower fixing block 214 to move forward, releasing the pressure on the fixing ball 215. The fixing ball 215 retracts into the fixing hole 216 and no longer locks the fixing pin 231. At this time, the fixing pin 231 can be removed from the fixing hole 22, completing the unlocking and disassembly of the camera.

[0035] The retraction of the pressing fixing block 214 allows the fixing ball 215 sufficient room to move. At this time, the fixing pin 231 is not in contact with the fixing ball 215, so the fixing pin 231 can be pulled out. The still limited room to move prevents the fixing ball 215 from completely disengaging from the fixing socket 216, so that it can be fixed next time.

[0036] Please see Figure 1 - Figure 5 At work,

[0037] First, fix the gimbal 1 to the rear of the bottom of the drone body 4 via the gimbal base 11. Then, place the camera 3 into the fixed bottom shell 21, cover it with the camera cover 232, and insert the fixing pin 231 into the fixing hole 22. Under the action of the fixing spring 212, the guide drive block 213 pushes the pressing fixing block 214 to squeeze the fixing ball 215. The fixing ball 215 is locked into the locking groove of the fixing pin 231, thus completing the camera fixing.

[0038] When unlocking, turn the unlocking knob 217 on the bottom shell body 211, which will drive the unlocking plate 218 to push the unlocking pin 219 to press the guide drive block 213, causing it to move upward and compress the fixing spring 212. The pressing down of the fixing block 214 will release the pressure on the fixing ball 215, and the fixing ball 215 will retract into the fixing socket 216. Pull out the camera cover 232 to remove the fixing pin 231, and the camera can be unlocked and removed.
