Abstract
Description
Technical Field
[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a gimbal shock absorption mechanism. Background Technology
[0002] With the rapid development of drone technology, drones have been widely used in various fields such as aerial photography, surveying, and agricultural spraying. To acquire high-quality image or video data, drones typically need to be equipped with mounts such as cameras and sensors. Since drones generate vibrations during flight, these vibrations can affect the stability of the mounts and the quality of data acquisition. Therefore, vibration damping mechanisms are usually installed between the drone and the mounts to reduce the impact of vibrations on the mounts.
[0003] When a drone is fitted with different weight-bearing devices, the original shock absorption mechanism cannot be adjusted, making it unable to adapt to the new weight distribution. This results in a decrease in shock absorption, affecting the stability of the mounted devices and the quality of data acquisition. Utility Model Content

[0035] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0036] As disclosed in the background section, when a drone is fitted with different weight-bearing devices, the original shock absorption mechanism cannot be adjusted, making it unable to adapt to the new weight distribution. This results in a decrease in shock absorption effectiveness, affecting the stability of the mounted devices and the quality of data acquisition. Embodiments of this application provide a gimbal shock absorption mechanism, at least to solve the aforementioned technical problems.
[0037] Please refer to Figures 1-5The gimbal shock absorption mechanism provided in the embodiments of this application includes a first bracket 100, a second bracket 200, and a shock absorption ball 300. The first bracket 100 is provided with a first mounting hole 111 and is used to mount a drone. The second bracket 200 is provided with a second mounting hole 211 and is used to mount a mounting device 500. The shock absorption ball 300 is detachably connected to both the first mounting hole 111 and the second mounting hole 211.
[0038] When it is necessary to install the mounting device 500 on the drone, the drone is connected to the first bracket 100, and the mounting device 500 is connected to the second bracket 200. The shock-absorbing ball 300 is simultaneously connected to the first mounting hole 111 and the second mounting hole 211, so that the first bracket 100 and the second bracket 200 are connected, thereby installing the mounting device 500 on the drone.
[0039] When the drone needs to be fitted with different weight mounts 500, the shock absorber ball 300 is simultaneously removed from the first mounting hole 111 and the second mounting hole 211, and then replaced with a similar shock absorber ball 300 that differs only in hardness. This shock absorber ball 300 can also connect to both the first mounting hole 111 and the second mounting hole 211. When mounting a heavier mount 500 on the second bracket 200, the shock absorber ball 300 with higher hardness is used; conversely, when mounting a lighter mount 500 on the second bracket 200, the shock absorber ball 300 with lower hardness is used. This gimbal damping mechanism allows for easy replacement of shock absorber balls 300 with different hardnesses to match different weight mounts 500.
[0040] In this embodiment, a first mounting portion 110 extends outward from the first bracket 100, and a first mounting hole 111 is formed in the first mounting portion 110; a second mounting portion 210 extends outward from the second bracket 200, and a second mounting hole 211 is formed in the second mounting portion 210; the shock-absorbing ball 300 engages with both the first mounting hole 111 and the second mounting hole 211.
[0041] The first mounting portion 110 extends outward from the bracket body of the first bracket 100, and the first mounting hole 111 is formed in the first mounting portion 110. The second mounting portion 210 extends outward from the bracket body of the second bracket 200, and the second mounting hole 211 is formed in the second mounting portion 210, thereby facilitating the installation of the shock-absorbing ball 300. When the shock-absorbing ball 300 is engaged with both the first mounting hole 111 and the second mounting hole 211, the first bracket 100 and the second bracket 200 are connected.
[0042] In this embodiment, the first mounting part 110 is provided with a first abutting ring 112 in the first mounting hole 111, and the second mounting part 210 is provided with a second abutting ring in the second mounting hole 211; the shock-absorbing ball 300 is made of elastic material, and the shock-absorbing ball 300 includes a ball 310 and a first snap-fit piece 320 and a second snap-fit piece 330 connected to opposite sides of the ball 310. A first slot and a second slot are formed between the ball 310 and the first snap-fit piece 320 and the second snap-fit piece 330, respectively. The first abutting ring 112 and the second abutting ring are respectively snapped into the first slot and the second slot.
[0043] The inner diameter of the first abutment ring 112 is smaller than the diameter of the first mounting hole 111, and the inner diameter of the second abutment ring is smaller than the diameter of the second mounting hole 211. The structure of the second abutment ring is similar to that of the first abutment ring 112. The shock-absorbing ball 300 includes a ball 310, a first snap-fit piece 320, and a second snap-fit piece 330. The shock-absorbing ball 300 is made of an elastic material, so that the ball 310, the first snap-fit piece 320, and the second snap-fit piece 330 can all undergo a certain degree of deformation.
[0044] During the replacement of the shock-absorbing ball 300, the first locking piece 320 is inserted into the first mounting hole 111 and passes through the first abutment ring 112. At this time, the first locking piece 320 deforms and returns to its original shape after passing the first abutment ring 112, so that the first abutment ring 112 is engaged in the first slot formed between the ball 310 and the first locking piece 320. Similarly, the second locking piece 330 is inserted into the second mounting hole 211 and passes through the second abutment ring. At this time, the second locking piece 330 deforms and returns to its original shape after passing the second abutment ring, so that the second abutment ring is engaged in the second slot formed between the ball 310 and the second locking piece 330.
[0045] In this embodiment, the shock-absorbing ball 300 is made of silicone. Of course, in other embodiments, the shock-absorbing ball 300 may be made of other elastic materials besides silicone, such as rubber, polyurethane or EVA, and there is no limitation on this.
[0046] In this embodiment, a guide post 321 is provided on the side of the first snap-fit piece 320 away from the ball 310, and the diameter of the guide post 321 is smaller than the inner diameter of the first abutment ring 112.
[0047] The guide post 321 is mainly used for guidance. In the actual assembly process, the second abutment ring is first engaged in the second slot formed between the ball 310 and the second snap-fit piece 330 to fix the shock-absorbing ball 300 and the second bracket 200. Then, the guide post 321 is passed through the first abutment ring 112. The guide post 321 guides the first snap-fit piece 320 to quickly pass through the first abutment ring 112 until the first abutment ring 112 is engaged in the first slot formed between the ball 310 and the first snap-fit piece 320, thus completing the rapid installation of the shock-absorbing ball 300.
[0048] In this embodiment, the first bracket 100 is provided with a plurality of first mounting portions 110 along its circumference, and each first mounting portion 110 is provided with a first mounting hole 111; the second bracket 200 is provided with a plurality of second mounting portions 210 along its circumference, and each second mounting portion 211 is provided with a second mounting hole 211; there are a plurality of shock-absorbing balls 300, and each shock-absorbing ball 300 simultaneously engages with the corresponding first mounting hole 111 and second mounting hole 211.
[0049] It is understandable that the number of the first mounting part 110, the second mounting part 210 and the shock-absorbing ball 300 are the same, and the number of the first mounting part 110, the second mounting part 210 and the shock-absorbing ball 300 can be determined according to the actual working conditions.
[0050] For example, there are four first mounting parts 110, four second mounting parts 210 and four shock-absorbing balls 300. The first bracket 100 is provided with four first mounting parts 110 along its circumference, and the second bracket 200 is provided with four second mounting parts 210 along its circumference. The four first mounting holes 111 and the four second mounting holes 211 are in corresponding positions, and each shock-absorbing ball 300 is engaged with the corresponding first mounting hole 111 and second mounting hole 211.
[0051] In this embodiment, the second bracket 200 is detachably provided with a connector 400 for mounting the device 500.
[0052] By configuring the connector 400 to be detachably connected to the second bracket 200, it is easy to assemble and disassemble the mounted device 500.
[0053] In this embodiment, the second bracket 200 has a through hole 220 and a third slot 230 is provided in the through hole 220. The connector 400 can rotate relative to the second bracket 200 around the central axis of the through hole 220. The connector 400 is provided with a protrusion 411 for engaging with the third slot 230.
[0054] The through hole 220 is a circular hole. A limiting ring 221 and a limiting strip 222 are provided inside the through hole 220. A third groove 230 is formed between the limiting ring 221 and the limiting strip 222. When the connector 400 is installed, the protrusion 411 on the connector 400 is inserted from one side of the limiting strip 222 into the space between the limiting ring 221 and the limiting strip 222. Then the connector 400 is rotated so that the protrusion 411 is engaged in the third groove 230 formed between the limiting ring 221 and the limiting strip 222, thereby realizing the connection between the connector 400 and the second bracket 200.
[0055] In order to ensure that the protrusion 411 can be stably held in the third slot 230, wedge-shaped surfaces that cooperate with each other can be provided on the protrusion 411 and the limiting strip 222. When the protrusion 411 and the limiting strip 222 cooperate through the wedge-shaped surfaces, the connector 400 and the second bracket 200 can be fixed by locking pins, and at this time the connector 400 can only rotate in one direction.
[0056] In this embodiment, the connector 400 includes a first connector 410 and a second connector 420 connected to each other. The second connector 420 extends out of the through hole 220 and has an anti-slip texture on its outer surface. The second connector 420 is used to install the mounting device 500. For example, the second connector 420 can be connected to the mounting device 500 by screws.
[0057] A raised strip 411 is provided on the first connector 410. The first connector 410 and the second connector 420 are detachably connected. The outer surface of the second connector 420 is provided with an anti-slip texture, so that it can play an anti-slip role when holding the anti-slip texture during the assembly process.
[0058] In this embodiment, the first connector 410 and the second connector 420 are connected by at least two screws.
[0059] The first connector 410 and the second connector 420 are connected by at least two screws, which can ensure good stability after the first connector 410 and the second connector 420 are connected. For example, the first connector 410 and the second connector 420 are connected by three or more screws.
[0060] In summary, this application provides a gimbal shock absorption mechanism. When the drone needs to replace the mounted equipment 500 with one of different weights, the shock-absorbing ball 300 is simultaneously removed from the first mounting hole 111 and the second mounting hole 211, and then replaced with a shock-absorbing ball 300 of different hardness. This shock-absorbing ball 300 can also connect to both the first mounting hole 111 and the second mounting hole 211 simultaneously. When a heavier mounted equipment 500 is mounted on the second bracket 200, a shock-absorbing ball 300 with higher hardness is used; conversely, when a lighter mounted equipment 500 is mounted on the second bracket 200, a shock-absorbing ball 300 with lower hardness is used. This gimbal shock absorption mechanism allows for easy replacement of shock-absorbing balls 300 of different hardness, thereby matching mounted equipment 500s of different weights.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
