DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The following is an explanation of the embodiments of the utility model based on its overall structure.

[0028] The specific implementation of the utility model is as follows:

[0029] As attached Figure 1-Figure 6 As shown, a shock-absorbing ball bracket for a drone camera includes:

[0030] A shock-absorbing ball fixing frame 1, wherein shock-absorbing balls 2 are symmetrically arranged on both sides of the two ends of the shock-absorbing ball fixing frame 1, and the shock-absorbing ball fixing frame 1 is connected to the shock-absorbing balls 2 through a bolt structure;

[0031] The pan / tilt card socket 4 is arranged in the middle of the shock-absorbing ball fixing frame 1 and has a plug hole 5 inside. The pan / tilt plug connector 6 of the pan / tilt camera 21 can be connected and locked with the plug hole 5 of the pan / tilt card socket 4;

[0032] Support seats 7, two support seats 7 are arranged on both sides of the shock-absorbing ball fixing frame 1, and a connecting sleeve 9 is provided in the middle of the two support seats 7, which passes through the side of the shock-absorbing ball fixing frame 1 and is adapted to the positioning piece on the base 8, and upper positioning rings 10 that can abut against the top of the shock-absorbing ball 2 are provided at both ends of the top of the support seat 7, and a connecting screw 3 connected and fixed to the shock-absorbing ball 2 is provided on the upper positioning ring 10.

[0033] The support seat 7 includes two support rods 11, a crossbeam 12 arranged at the top of the two support rods 11 and a connecting sleeve 9 connected to the bottom of the two support rods 11. The connecting sleeve 9 can be connected with the positioning piece on the base 8. The base 8 is used to connect to the top surface of the drone. The connecting sleeve 9 is provided with a mounting hole, and the mounting hole is provided with a locking screw 13 connected to the screw hole on the positioning piece on the base 8.

[0034] In the shock-absorbing ball bracket of the drone camera, the support seat 7 is inserted into both sides of the shock-absorbing ball fixing frame 1, and the upper positioning rings 10 at both ends of the support seat 7 are in contact with the shock-absorbing ball 2, and then the upper positioning ring 10 is connected to the top of the shock-absorbing ball 2 through the connecting screw 3, so that the support seat 7 and the shock-absorbing ball fixing frame 1 are assembled into a whole and then connected to the base 8, and the connecting sleeve 9 at the bottom of the support seat 7 is connected with the positioning piece on the base 8 for positioning, and then the connecting sleeve 9 and the positioning piece on the base 8 are locked by the locking screw 13; then, the pan-tilt plug connector 6 of the pan-tilt camera 21 can be quickly screwed into the plug hole 5 of the pan-tilt card sleeve 4, and the pan-tilt camera 21 can be installed on the shock-absorbing ball bracket.

[0035] In the shock-absorbing ball bracket of the drone camera, the gravity of the gimbal camera 21 is applied to the shock-absorbing ball fixing frame 1, and the pressure and gravity exerted on the shock-absorbing ball fixing frame 1 are applied to the bolt structure at the bottom of the shock-absorbing ball 2, pulling the shock-absorbing ball 2 downward, and the force exerted on the shock-absorbing ball 2 is transmitted to the support seat 7, and then the gravity is exerted on the shock absorber base 8; since the shock-absorbing ball 2 is arranged between the support seat 7 and the shock-absorbing ball fixing frame 1, when the drone is flying, the gimbal camera 21 and the drone are subjected to vibrations caused by airflows of different directions and flow rates, and the vibrations can be quickly transmitted to the shock-absorbing balls, thereby quickly achieving the shock-absorbing effect, and the vibrations generated by the support seat 7 and the shock-absorbing ball fixing frame 1 are reduced by the shock-absorbing balls 2, thereby reducing the vibration amplitude and vibration frequency of the gimbal camera 21 and the drone, thereby ensuring the quality of the captured images.

[0036] In this embodiment, a sleeve hole 20 adapted to the positioning piece on the base 8 is opened on the bottom surface of the connecting sleeve 9. The sleeve hole 20 is sleeved on the positioning piece of the base 8 to quickly position the support seat 7 and the base 8, and then fixed by the locking screw 13.

[0037] In this embodiment, the cross beam 12 is hollowed out with a plurality of weight-reducing holes, and the upper positioning rings 10 are arranged at both ends of the cross beam 12. Providing weight-reducing holes can reduce the weight of the bracket, reduce the energy consumption of the UAV flight, and also reduce the stress concentration of the support seat 7 during the one-piece molding manufacturing.

[0038] In this embodiment, the support rod 11 is an oblique support rod structure that is tilted outward, and the two ends of the cross beam 12 are provided with extension parts 14 that are bent outward. The upper positioning ring 10 is arranged at the end of the extension part 14. The support seat 7 is made of plastic material and can undergo a small elastic deformation. The support rod 11 is arranged obliquely so that when the upper positioning ring 10 is subjected to a downward pulling force, the oblique support rod structure can bend slightly to resist the vibration force.

[0039] In this embodiment, the shock-absorbing ball fixing frame 1 is a hollowed-out plastic plate structure, and both sides of the shock-absorbing ball fixing frame 1 are provided with a connecting sleeve 9 for the support seat 7 and a clearance hole 15 for two support rods 11 to pass through. The setting of the clearance hole 15 is to facilitate the support rod 11 to be inserted downward and connected with the base 8.

[0040] In this embodiment, the four corners of the shock-absorbing ball fixing frame 1 are provided with lower positioning rings 16 that abut against the bottom of the shock-absorbing ball 2. The lower positioning ring 16 abuts against the bottom of the shock-absorbing ball 2 to position the shock-absorbing ball 2, and then the lower positioning ring 16 is fixedly connected to the shock-absorbing ball 2 through the connecting screw 3. The lower positioning ring 16 and the upper positioning ring 10 abut against the shock-absorbing ball 2, which increases the contact surface area, so that when it is connected with the shock-absorbing ball 2, the contact area is large, the fit is high, and it is not easy to shift, thereby improving the stability of the shock-absorbing effect.

[0041] In this embodiment, the shock-absorbing ball fixing frame 1 includes a flat plate 17 located in the middle and four wing plates 18 arranged on the sides of the flat plate 17. The two ends of the flat plate 17 are narrowed to reduce the weight of the shock-absorbing ball fixing frame 1. The clearance holes 15 are arranged on both sides of the flat plate 17. The wing plates 18 are provided with hollow holes 19. The wing plates 18 are tilted downward at an angle of 5°-10°. The lower positioning ring 16 is arranged at the end of the wing plates 18. The shock-absorbing ball fixing frame 1 is of lightweight design, with less structural materials and light weight.

[0042] In this embodiment, a micro air pump is arranged at the bottom of the gimbal adapter sleeve 4, which is connected to the shock-absorbing ball 2 through a hose. A micro air valve is arranged on the hose. The micro air pump and the micro air valve can be controlled to open or close through the remote control handle of the drone, and air can be supplied and deflated to each shock-absorbing ball 2, the air pressure of the shock-absorbing ball 2 can be adjusted, and the hardness of the shock-absorbing ball bracket can be adjusted, so as to achieve a shock-absorbing effect in various environments.

[0043] This drone camera shock-absorbing ball bracket is made of aluminum-magnesium alloy material as a whole, with a thin-wall combination. It is lightweight and high-strength, not easy to damage, suitable for various complex working environments, and improves overall safety.
