[0002] With the rapid development of drone technology, aerial photography has become an important tool in fields such as film and television production, geographic surveying, news reporting, and agricultural monitoring. Drones can break through the limitations of ground-based perspectives, capturing vast and unique images, providing various industries with an efficient and convenient way to acquire video.

[0003] Most existing anti-vibration gimbal brackets for drone aerial photography cameras adopt a fixed connection structure during use. When the gimbal bracket is damaged and needs to be repaired or replaced, the disassembly process is complicated and not conducive to quick maintenance. Secondly, the positioning structure of some brackets only focuses on fixing the position and lacks a buffer design to cope with external impacts. When encountering bumps, the connection parts are easily damaged due to hard contact.

[0004] Therefore, a shock-absorbing gimbal bracket for drone aerial cameras is proposed to address the above issues. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a shockproof gimbal bracket for drone aerial photography cameras. It features convenient detachability between the gimbal bracket body and the mounting base, facilitating later maintenance and replacement operations and reducing the impact of hard collisions.

[0009] Preferably, the inner diameter of the four insertion holes is adapted to the outer diameter of the locking rod, and the inner wall of the insertion holes is provided with a wear-resistant coating.

[0010] Preferably, the locking rod further includes a limiting plate that is fixedly sleeved with the outer surface of the locking rod, and one end of the limiting plate abuts against the bottom end of the gimbal bracket body.

[0011] Preferably, the drive block is frustum-shaped.

[0012] Preferably, the outer surface of the drive block is provided with four limiting grooves, and one end of each of the four snap-fit ​​rods is fixedly connected to a limiting block that cooperates with the limiting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1.

[0028] 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.

[0029] like Figures 1 to 6 As shown, this utility model provides a shockproof gimbal bracket for a drone aerial camera, including a drone body 1. The bottom of the drone body 1 is provided with a mounting base 2, and the mounting base 2 and the drone body 1 are an integral structure. The connection strength between the integrated mounting base 2 and the drone body 1 is enhanced. The bottom of the mounting base 2 is provided with a gimbal bracket body 3. Several silicone positioning protrusions 21 are fixedly connected to the top of the gimbal bracket body 3. The bottom of the mounting base 2 is provided with positioning grooves 13 that cooperate with the positioning protrusions 21. The bottom of the mounting base 2 is provided with four insertion holes 11. Four locking rods 4 are inserted into the inner surface of the gimbal bracket body 3. The tops of the four locking rods 4 all penetrate the gimbal bracket body 3 and extend into the four insertion holes 11 respectively. At the same time, by utilizing the cooperation of the positioning protrusions 21 and the positioning grooves 13 and the insertion of the locking rods 4 into the insertion holes 11, a multi-connection structure is formed, which fundamentally prevents the gimbal bracket body 3 from falling off and provides basic stability for the overall structure.

[0030] Specifically, the depth of the positioning groove 13 is less than the height of the positioning protrusion 21, and the end of the positioning protrusion 21 away from the gimbal bracket body 3 abuts against the bottom of the positioning groove 13. The depth of the positioning groove 13 is less than the height of the positioning protrusion 21, so that the positioning protrusion 21 is always in a compressed abutting state. This not only enhances the tightness of the connection through the elasticity of silicone, but also forms elastic support, which, together with the main connection structure, further prevents the gimbal bracket body 3 from loosening and falling off.

[0031] like Figures 1 to 6 As shown, the locking rod 4 includes an operating rod 42. The outer surface of the operating rod 42 is slidably sleeved with the inner surface of the locking rod 4. A driving block 43 is fixedly connected to one end of the operating rod 42 located inside the locking rod 4. A support spring 44 is fixedly connected to the top of the driving block 43. One end of the support spring 44 is fixedly connected to the upper inner wall of the locking rod 4. Four locking rods 432 are slidably connected to the outer surface of the driving block 43. Four locking grooves 12 are opened on the inner surface of the insertion hole 11. One end of each of the four locking grooves 12 passes through the locking rod 4 and extends into the four locking grooves 12 respectively. Through the locking structure composed of the operating rod 42, the driving block 43, the support spring 44 and the locking rods 432, the locking rod 4 and the insertion hole 11 are rigidly locked, providing core fixing force for the gimbal bracket body 3, effectively preventing it from detaching from the mounting base 2, and realizing tool-free quick assembly and disassembly.

[0032] Furthermore, the inner diameter of the four insertion holes 11 is adapted to the outer diameter of the locking rod 4, and the inner wall of the insertion holes 11 is provided with a wear-resistant coating. The size compatibility between the insertion holes 11 and the locking rod 4 ensures that the two fit tightly, reducing the loosening of the connection caused by gap wobble. The wear-resistant coating reduces the wear gap after long-term use, maintains the fitting accuracy, and indirectly prevents the gimbal bracket body 3 from falling off due to excessive gap.

[0033] like Figures 1 to 6 As shown, the locking rod 4 also includes a limiting plate 41 that is fixedly sleeved on the outer surface of the locking rod 4. One end of the limiting plate 41 abuts against the bottom end of the gimbal bracket body 3. The abutting structure between the limiting plate 41 and the bottom end of the gimbal bracket body 3 forms a reverse support force, which directly prevents the gimbal bracket body 3 from falling off the locking rod 4 due to gravity or vibration, thus eliminating the risk of falling off.

[0034] It is worth noting that the drive block 43 is frustum-shaped. The frustum-shaped drive block 43 makes the extension and retraction of the locking rod 432 smoother, ensuring reliable locking of the locking structure and preventing the locking rod 4 from loosening due to locking failure, thereby indirectly ensuring the connection stability of the gimbal bracket body 3.

[0035] like Figures 1 to 6As shown, the outer surface of the drive block 43 is provided with four limiting grooves 431. One end of each of the four locking rods 432 is fixedly connected to a limiting block 433 that works in conjunction with the limiting groove 431. The cooperation between the limiting block 433 and the limiting groove 431 ensures that the locking rod 432 always moves along the preset trajectory, preventing the locking rod 432 from deviating or jamming and causing locking failure, ensuring the reliability of the connection between the locking rod 4 and the insertion hole 11, and thus preventing the gimbal bracket body 3 from falling off.

[0036] Working principle and process: During installation, first press the operating lever 42, which drives the drive block 43 to move down and compress the support spring 44, causing the locking rod 432 to retract into the locking rod 4. Then, insert the locking rod 4 into the insertion hole 11, while simultaneously embedding the positioning protrusion 21 into the positioning groove 13. After insertion, release the operating lever 42, and the support spring 44 pushes the drive block 43 to move up. The locking rod 432 pops out under the action of the drive block 43 and locks into the locking groove 12 to complete the locking. At this time, the limiting plate 41 abuts against the bottom of the gimbal bracket body 3 to form a limit. The precise cooperation between the positioning protrusion 21 and the positioning groove 13 achieves the initial positioning of the gimbal bracket body 3 and the mounting base 2, ensuring that the locking rod 4 can be accurately aligned with the insertion hole 11. At the same time, the silicone positioning protrusion 21 can provide a certain elastic pre-tightening force, which, together with the insertion of the locking rod 4 and the insertion hole 11, forms a multiple connection foundation and improves the overall structural stability.
