Description

Technical Field

[0001] This utility model relates to the field of drone mounting accessories technology, and in particular to a drone gimbal mounting structure. Background Technology

[0002] With the continuous development of drone technology, its application in fields such as aerial photography, surveying and mapping, and inspection is becoming more and more widespread. Among them, the stability of the drone gimbal itself is an important performance indicator of the gimbal, which directly affects the gimbal's image stabilization effect. A reasonable and stable gimbal structure plays a significant role in improving the drone's operational performance. When using a drone gimbal, it needs to be connected to the bottom of the drone through a mounting structure.

[0003] When the existing drone gimbal mounting structure becomes loose during use, the gimbal is prone to swaying under the drone, resulting in decreased gimbal stability and poor shooting quality. Furthermore, when the existing drone gimbal mounting structure becomes loose to a certain extent, the gimbal will fall off and be lost, causing damage.

[0004] An existing patent (publication number: CN218617202U) discloses a mounting structure for a drone gimbal. This utility model solves the problem that existing drone gimbal mounting structures cannot remain stable after loosening and cannot prevent the drone gimbal from being lost by setting up a connecting plate, connecting plate, movable ring and screw. It ensures that the gimbal can remain stable under the drone even after it is loosened during use, and can prevent the gimbal from being lost from the drone.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the existing gimbal mounting structure for drones is not convenient for installing and removing the gimbal, resulting in cumbersome operations and reduced work efficiency. At the same time, the gimbal mounting structure has poor versatility and cannot be adapted to various gimbal models, thus limiting the scope of drone use.

[0006] To address this, a gimbal mounting structure for unmanned aerial vehicles (UAVs) is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a gimbal mounting structure for drones, which can solve the problems of existing gimbal mounting structures for drones being inconvenient to install and disassemble, resulting in cumbersome operation and reduced work efficiency. At the same time, the gimbal mounting structure has poor versatility and cannot be adapted to various models of gimbals, thus limiting the scope of use of drones.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a UAV gimbal mounting structure, including a fixing plate, a shock-absorbing structure at the bottom of the fixing plate, a mounting plate at the bottom of the shock-absorbing structure, and a fixing component at the bottom of the mounting plate;

[0009] The fixing assembly includes a sliding groove formed at the bottom of the mounting plate. A bidirectional lead screw is rotatably connected inside the sliding groove. The front side of the bidirectional lead screw penetrates the front side of the sliding groove. An internal hexagon block is fixedly connected to the front side of the bidirectional lead screw. Sliding blocks are threaded to both sides of the surface of the bidirectional lead screw. The sliding blocks are slidably connected inside the sliding groove. A magnet is embedded in the bottom of the mounting plate. The magnet is located at the bottom of the sliding groove. A fastening limiting plate is fixedly connected to the bottom of the sliding block. The fastening limiting plate is located outside the magnet.

[0010] Preferably, the shock-absorbing structure includes a connecting plate fixedly connected to the bottom of the fixed plate, and the four corners of the top of the connecting plate are provided with slots.

[0011] Preferably, spring shock absorbers are bolted to each of the four corners of the top of the mounting plate, and the top of the spring shock absorber passes through the bottom of the slot.

[0012] Preferably, a rubber shock-absorbing ball is fitted on the top of the outer side of the spring shock absorber, the top of the rubber shock-absorbing ball contacts the bottom of the connecting plate, and a fastening nut is threadedly connected to the top of the spring shock absorber, the fastening nut being located at the top of the slot.

[0013] Preferably, an isolation pad is adhered to the top of the fixing plate, and the top of the isolation pad is coated with a wear-resistant coating.

[0014] Preferably, a deformation-fitting pad is adhered to the inner side of the fastening limiting plate, and the deformation-fitting pad is made of elastic rubber material.

[0015] Preferably, a reinforcing sleeve is snapped onto the outside of the fastening nut, and the bottom of the reinforcing sleeve is bonded to the top of the connecting plate.

[0016] Preferably, an elastic cotton block is adhered to the top of the reinforcing sleeve, and the thickness of the elastic cotton block is greater than the thickness of the insulating pad.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting a fixing component, allows the operator to use an Allen wrench to rotate the Allen block fixed to the double-ended screw when installing the gimbal. The rotation of the double-ended screw drives the two side blocks to slide towards each other in the sliding groove, causing the fastening limit plate to move inward. During this process, the gimbal is placed at the bottom of the mounting plate near the magnet, and is initially fixed by the attraction of the magnet. Then, the Allen block is rotated to make the fastening limit plate press tightly against the side of the gimbal, completing the stable clamping. This method is simple to operate and does not require complicated tools, improving installation efficiency. It can also adapt to different sizes of gimbals by adjusting the double-ended screw, expanding its versatility. Disassembly is done by reversing the operation; the gimbal can be quickly removed by easily turning the Allen block, reducing tedious operations and making it convenient to use.

[0019] 2. This application incorporates a shock-absorbing structure located between the fixed plate and the mounting plate. During drone flight, the fuselage is inevitably subjected to vibrations caused by various factors such as airflow impact and engine vibration. The shock-absorbing structure can absorb and buffer these vibrations, preventing them from being directly transmitted to the fixed components and gimbal. This ensures that the fixed components and the shooting equipment mounted on the gimbal can operate smoothly, capturing clear and stable images and improving the quality of drone operations.

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A drone gimbal mounting structure includes a fixing plate 1, a shock-absorbing structure 2 at the bottom of the fixing plate 1, a mounting plate 3 at the bottom of the shock-absorbing structure 2, and a fixing component 4 at the bottom of the mounting plate 3.

[0029] The fixing component 4 includes a shifting groove 401 formed at the bottom of the mounting plate 3. A bidirectional lead screw 402 is rotatably connected inside the shifting groove 401. The front side of the bidirectional lead screw 402 passes through the front side of the shifting groove 401. An internal hexagon block 403 is fixedly connected to the front side of the bidirectional lead screw 402. Shifting blocks 404 are threadedly connected to both sides of the surface of the bidirectional lead screw 402. Shifting blocks 404 are slidably connected inside the shifting groove 401. A magnet 405 is embedded in the bottom of the mounting plate 3. The magnet 405 is located at the bottom of the shifting groove 401. A fastening limiting plate 406 is fixedly connected to the bottom of the shifting block 404. The fastening limiting plate 406 is located outside the magnet 405.

[0030] In this embodiment: By setting the shock-absorbing structure 2 and the fixing component 4, the fixing plate 1, which carries the shock-absorbing structure 2, the mounting plate 3, and the fixing component 4, is first installed and fixed to the designated position on the bottom of the drone. When the gimbal needs to be installed, the operator uses a suitable wrench to gently rotate the internal hexagon block 403, which is tightly fixed to the front side with the bidirectional lead screw 402. Since the bidirectional lead screw 402 passes through the front side of the sliding groove 401 and is rotatably connected to it, under the torque applied by the wrench, the bidirectional lead screw 402 begins to rotate, causing the sliding blocks 404 on both sides to slide towards each other within the track defined by the sliding groove 401. The fastening limiting plate 406, which is firmly connected to the bottom of the sliding block 404, also moves inward synchronously. At the same time, the gimbal is placed at the bottom of the mounting plate 3, close to the magnet 405 embedded at the bottom. The magnet 405, with its strong magnetic force, instantly attracts the part of the gimbal that is close to it, initially fixing the position of the gimbal and preventing it from shaking randomly in subsequent operations. Then, the operator continues to rotate the internal hexagon block 403, allowing... The fastening limiting plate 406 continues to push inward until it firmly presses against the side of the gimbal, providing a stable clamping grip on the gimbal from multiple directions. Moreover, regardless of the size of the gimbal, simply rotating the bidirectional lead screw 402 and adjusting the spacing of the shift block 404 allows for flexible adaptation to different sizes. Subsequently, when it is time to disassemble the gimbal, the above operation is repeated in reverse. The internal hexagon block 403 is easily turned, and the shift block 404 causes the fastening limiting plate 406 to loosen its grip on the gimbal, allowing for quick removal of the gimbal. This greatly reduces the complexity of the operation, making the use of the drone more convenient and efficient. The shock-absorbing structure 2, located between the fixed plate 1 and the mounting plate 3, absorbs and buffers the vibrations caused by airflow impacts, engine vibrations, and other factors during drone flight. This prevents the vibrations from being directly transmitted to the gimbal, ensuring that the shooting equipment mounted on the gimbal can operate smoothly and capture clear and stable images, thus improving the quality of drone operations.

[0031] Specifically, such as Figure 2 As shown, the shock-absorbing structure 2 includes a connecting plate 201 fixedly connected to the bottom of the fixed plate 1, and the four corners of the top of the connecting plate 201 are provided with holes and slots 202.

[0032] Specifically, such as Figure 2 As shown, spring shock absorbers 203 are bolted to the four corners of the top of the mounting plate 3, and the top of the spring shock absorber 203 passes through the bottom of the slot 202.

[0033] Specifically, such as Figure 2 As shown, a rubber damping ball 204 is sleeved on the top of the outer side of the spring damper 203. The top of the rubber damping ball 204 contacts the bottom of the connecting plate 201. A fastening nut 205 is threadedly connected to the top of the spring damper 203. The fastening nut 205 is located at the top of the slot 202.

[0034] In this embodiment: By setting up the shock absorption structure 2, when the drone encounters airflow impact and body vibration, the spring shock absorber 203 can quickly expand and contract due to its own elasticity, effectively buffering the vibration energy and preventing the vibration from being directly transmitted to the fixed component 4 at the bottom and the gimbal. At the same time, the rubber shock absorption ball 204 sleeved on the top of the outer side of the spring shock absorber 203 contacts the bottom of the connecting plate 201, further enhancing the buffering effect. The flexibility of the rubber material can absorb the minor impacts brought by the vibration. Working together with the spring shock absorber 203, it greatly reduces the vibration amplitude transmitted to the gimbal, ensuring that the fixed component 4 and the shooting equipment mounted on the gimbal can operate smoothly. In addition, the fastening nut 205 with the threaded connection at the top of the spring shock absorber 203 is located at the top of the slot 202. It not only ensures the stability of the spring shock absorber 203 during operation and prevents it from loosening due to vibration, but also allows for fine adjustment of the shock absorption effect by adjusting the tightness to adapt to the shock absorption requirements under different working conditions.

[0035] Specifically, such as Figure 1 , Figure 4 As shown, an isolation pad 5 is adhered to the top of the fixing plate 1, and the top of the isolation pad 5 is coated with a wear-resistant coating.

[0036] Specifically, such as Figure 3 As shown, a deformable bonding pad 6 is bonded to the inner side of the fastening limiting plate 406. The deformable bonding pad 6 is made of elastic rubber material.

[0037] In this embodiment: by setting the isolation pad 5, on the one hand, it can isolate the slight vibration that the fixing plate 1 may transmit, further enhancing stability. On the other hand, the wear-resistant coating on its top effectively resists friction wear in daily use, extending the service life of the fixing plate 1. By setting the deformation fitting pad 6, it utilizes the high elasticity and high friction characteristics of elastic rubber to tightly fit the surface of the gimbal when the clamping limit plate 406 holds the gimbal. It can adapt to the shape of the gimbal to provide a uniform and stable clamping force, preventing the gimbal from shaking, and also avoids scratching damage to the gimbal, ensuring that the appearance of the gimbal and the internal precision components are not affected.

[0038] Specifically, such as Figure 5 As shown, a reinforcing sleeve 7 is snapped onto the outside of the fastening nut 205, and the bottom of the reinforcing sleeve 7 is bonded to the top of the connecting plate 201.

[0039] Specifically, such as Figure 5 As shown, an elastic cotton block 8 is bonded to the top of the reinforcing sleeve 7, and the thickness of the elastic cotton block 8 is greater than the thickness of the isolation pad 5.

[0040] In this embodiment: By setting the reinforcing sleeve 7, it provides additional protection for the fastening nut 205, preventing it from accidentally loosening in the frequent vibration environment of the drone, and ensuring that the shock absorption function of the spring shock absorber 203 remains effective. By setting the elastic cotton block 8, it can contact the bottom of the drone. With its own thickness advantage and soft material characteristics, it can act as a secondary buffer layer during the vibration of the drone flight, absorbing the residual vibration from components such as the fastening nut 205 and the connecting plate 201, further reducing the impact of vibration on the gimbal. Together with the previous shock absorption structure 2 and the isolation pad 5, it forms a multi-layer shock absorption protection system, ensuring that the gimbal is in a stable operating state in all aspects.

[0041] Working Principle: During the use of the drone gimbal mounting structure, firstly, the fixing plate 1 is precisely installed at the designated position on the bottom of the drone. When installing the gimbal, the operator picks up the appropriate wrench, gently touches and slowly rotates the internal hexagon block 403 located on the front side, which is tightly connected to the bidirectional lead screw 402. Since the bidirectional lead screw 402 passes through the front side of the sliding groove 401 and is rotatably connected, under the torque drive of the wrench, the bidirectional lead screw 402 rotates. Its carefully designed reverse thread causes the two sliding blocks 404 to slide towards each other in the track of the sliding groove 401. The bottom fastening limit plate 406 of the sliding block 404 moves inward simultaneously. At the same time, the gimbal is gently placed on the bottom of the mounting plate 3, close to the embedded magnet 405. The strong magnetic force... The device instantly grips a portion of the gimbal, initially fixing its position. The operator then continues to rotate the Allen wrench 403, tightening the limiting plate 406 inwards until it firmly presses against the side of the gimbal, securing it from multiple angles. This installation method is simple, requiring only an Allen wrench and eliminating the need for complicated tools, significantly reducing installation time and improving efficiency. Furthermore, by adjusting the two-way screw 402, it can accommodate gimbals of different sizes. Disassembly is done by reversing the operation; simply turning the Allen wrench 403 allows for quick and easy removal of the gimbal. The operation is convenient and efficient. During flight, the shock-absorbing structure 2 plays a role. When the drone encounters airflow impacts or engine vibrations, the four corner slots 202 of the connecting plate 201, fixed to the bottom of the mounting plate 1, are bolted to the four corners of the mounting plate 3. The spring damper 203 is precisely matched, and it expands and contracts rapidly according to vibration, buffering a large amount of vibration energy and preventing it from being directly transmitted to the gimbal. The rubber damping ball 204 fitted on the top of the spring damper 203 contacts the bottom of the connecting plate 201 with its flexibility, absorbing minor impacts and working with the spring damper 203 to reduce the vibration amplitude. The fastening nut 205, located at the top of the slot 202 and threadedly connected to the spring damper 203, not only secures the spring damper 203 to prevent loosening, but also allows for fine-tuning of the damping effect as needed. In addition, the isolation pad 5 and its wear-resistant coating adhered to the top of the fixing plate 1 play a role. The isolation pad 5 isolates minor vibrations and enhances stability, while the wear-resistant coating resists daily friction wear and extends the fixation period. The lifespan of plate 1 is enhanced by the elastic rubber deformation-adhesive pad 6 on the inner side of the fastening limit plate 406. This pad fits tightly and adapts to deformation when clamping the gimbal, providing stable clamping force, preventing gimbal swaying, and avoiding scratch damage. Furthermore, the reinforcing sleeve 7, which is snapped onto the outside of the fastening nut 205, is bonded to the top of the connecting plate 201 at the bottom. This protects the fastening nut 205 from the risk of loosening due to vibration and ensures the continuous effectiveness of the spring shock absorber 203. An elastic cotton block 8 with a thickness greater than the isolation pad 5 is bonded to the top of the reinforcing sleeve 7. This block contacts the bottom of the drone and acts as a secondary buffer layer to absorb residual vibration. Together with other components, it forms multiple shock absorption protections, ensuring the smooth operation of the gimbal-mounted equipment from all angles, capturing clear and stable images, and improving the quality of drone operations.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
