Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle brackets, and specifically, to an unmanned aerial vehicle bracket assembly. Background Art

[0002] Currently, in order to prevent pests and diseases in rice planting, unmanned aerial vehicles are often used to take pictures of rice images to achieve real-time monitoring of rice pests and diseases for early warning. Generally, an unmanned aerial vehicle for taking pictures includes a fuselage, wings and a bracket. These three parts are generally designed to be separable and need to be assembled subsequently. During the assembly process, screws or bolts are generally used for assembly and fixation. There is also a way to directly set legs on the fuselage as a bracket.

[0003] When the unmanned aerial vehicle falls to the ground during flight, a certain impact force will be generated. However, most of the current brackets of unmanned aerial vehicles are rigid brackets. Therefore, when the unmanned aerial vehicle falls to the ground, it is easy for the unmanned aerial vehicle to be subjected to a collision force, resulting in the vibration of the fuselage and wings of the unmanned aerial vehicle. Over time, the fuselage and wings of the unmanned aerial vehicle may become loose or fall off, thus affecting the service life of the unmanned aerial vehicle. Summary of the Utility Model

[0004] The utility model provides an unmanned aerial vehicle bracket assembly, which can overcome the defects of the prior art.

[0005] According to an unmanned aerial vehicle bracket assembly of the utility model, it includes: a component main body, the component main body includes a mounting seat, and support frames are arranged on both sides of the mounting seat; the support frame includes two arc-shaped support rods, one end of the support rod is provided with a connecting rod connecting the two support rods, and the other end of the support rod is provided with a clamping block; a groove for the clamping block to extend into is arranged on the side wall of the mounting seat; a first spring is arranged in the groove, and the first spring is used to keep the clamping block always have a tendency to move downward.

[0006] By means of the utility model, when an impact force is generated when the unmanned aerial vehicle falls to the ground, the support frame first contacts the ground, and then the fuselage of the unmanned aerial vehicle presses down, causing the mounting seat to move downward. At this time, the clamping block slides in the groove and compresses the first spring, and the first spring is compressed; thereby offsetting the impact force and playing a buffering role for the fuselage; after the impact force disappears, the first spring resumes its original state; thus reducing the vibration of the fuselage and wings of the unmanned aerial vehicle, reducing the occurrence of wing loosening or falling off, and prolonging the service life of the unmanned aerial vehicle.

[0030] Embodiment 1

[0031] As Figures 1-9 shown. In this embodiment, a drone bracket assembly is provided, including an assembly main body 100. The assembly main body 100 includes a mounting seat 110, and support frames 120 are provided on both sides of the mounting seat 110; each support frame 120 includes two arc-shaped support rods 320. One end of each support rod 320 is provided with a connecting rod 310 connecting the two support rods 320, and the other end of each support rod 320 is provided with a clamping block 340; a groove 130 for the clamping block 340 to extend into is provided on the side wall of the mounting seat 110; a first spring 201 is provided in the groove 130, and the first spring 201 is used to keep the clamping block 340 always having a tendency to move downward.

[0032] Through this embodiment, when the drone hits the ground and generates an impact force, the support frame 120 first contacts the ground. Then, the fuselage of the drone presses down, causing the mounting seat 110 to move downward. At this time, the clamping block 340 slides in the groove 130 and compresses the first spring 201, and the first spring 201 is compressed; thereby offsetting the impact force and playing a buffering role for the fuselage; after the impact force disappears, the first spring 201 resumes its original state; thereby reducing the vibration received by the fuselage and wings of the drone, reducing the occurrence of wing loosening or falling off, and extending the service life of the drone.

[0033] In this embodiment, the groove 130 includes a first sub-groove 240 and a second sub-groove 270, and the first sub-groove 240 and the second sub-groove 270 are communicated; a first guide rod 260 passing through the first sub-groove 240 and the second sub-groove 270 is provided in the groove 130. A lifting plate 250 arranged along the length direction of the first sub-groove 240 is provided in the first sub-groove 240, and a first through hole 920 for the first guide rod 260 to pass through is provided at the lifting plate 250; the first spring 201 is sleeved on the first guide rod 260 and is located in the first sub-groove 240; a second through hole 330 for the first guide rod 260 to pass through is provided at the clamping block 340, and the clamping block 340 is located in the second sub-groove 270;

[0034] The mounting base 110 includes an upper mounting plate 210 and a lower mounting plate 230. The groove 130 is located at the upper mounting plate 210. The upper mounting plate 210 and the lower mounting plate 230 are connected by bolts 220.

[0035] In this embodiment, when the drone falls to the ground and generates an impact force, the clamping block 340 moves along the first guide rod 260 to push the lifting plate 250, so that the clamping block 340 is more stable when moving. Since the support frame 120 often rubs or impacts with the ground, when the support frame 120 is damaged, the staff can remove the bolt 220 connecting the upper mounting plate 210 and the lower mounting plate 230, and then remove the clamping block 340 on the support rod 320 from the first guide rod 260 in the second sub-groove 270. When removing the clamping block 340, the first spring 201 always presses the lifting plate 250, so that the lifting plate 250 abuts against the inner side wall of the first sub-groove 240, thus not affecting the staff to remove the clamping block 340 from the second sub-groove 270, thereby facilitating the staff to replace the damaged support frame 120.

[0036] Both the upper mounting plate 210 and the lower mounting plate 230 are provided with a first bolt hole 730 and a second bolt hole 620 that cooperate with the bolt 220.

[0037] In this embodiment, second guide rods 290 are provided on both sides of the first guide rod 260 and are located in the first sub-groove 240. The lifting plate 250 is provided with a third through hole 910 for the second guide rod 290 to pass through.

[0038] In this embodiment, when the lifting plate 250 is pushed by the clamping block 340, it moves along the first guide rod 260 and the second guide rod 290, thereby preventing the lifting plate 250 from shifting when moving and improving the stability of the lifting plate 250 during movement.

[0039] In this embodiment, a second spring 280 sleeved on the second guide rod 290 is provided in the first sub-groove 240.

[0040] In this embodiment, under the combined action of the first spring 201 and the second spring 280, the stability of the drone during falling can be better maintained.

[0041] In this embodiment, fourth through holes 710 for the second guide rod 290 to pass through are provided on both sides of the second sub-groove 270. A threaded blind hole 510 for the first guide rod 260 and the second guide rod 290 to extend into is provided at the side wall of the first sub-groove 240 far from the second sub-groove 270. External threads 810 are provided on the outer side walls of the ends of the first guide rod 260 and the second guide rod 290 extending into the threaded blind hole 510.

[0042] In this embodiment, when the staff installs the component main body 100, the lifting plate 250 can be first inserted into the first sub-groove 240, and then the first guide rod 260 is passed through the first sub-groove 240, the second sub-groove 270 and the first through-hole 920 on the lifting plate 250 and extends into the threaded blind hole 510. Then the first guide rod 260 is rotated and screwed into the threaded blind hole 510. Then the second guide rod 290 is passed through the fourth through-hole 710 and the third through-hole 910 on the lifting plate 250 and extends into the threaded blind hole 510, thereby fixing the lifting plate 250. Before the first guide rod 260 and the second guide rod 290 extend into the threaded blind hole 510, the staff places the first spring 201 and the second spring 280 into the first sub-groove 240 for the first guide rod 260 and the second guide rod 290 to pass through, which preferably facilitates the staff to install the first guide rod 260, the second guide rod 290, the first spring 201, the second spring 280 and the lifting plate 250 in the groove 130.

[0043] After the installation of the first guide rod 260, the second guide rod 290, the first spring 201, the second spring 280 and the lifting plate 250 is completed, the staff sleeves the block 340 on the first guide rod 260, and finally connects the upper mounting plate 210 and the lower mounting plate 230 through the bolts 220.

[0044] In this embodiment, the lower mounting plate 230 is provided with blind holes 520 for one end of the first guide rod 260 and the second guide rod 290 to extend into.

[0045] Through this embodiment, after the installation of the first guide rod 260, the second guide rod 290, the first spring 201, the second spring 280 and the lifting plate 250 is completed, when connecting the upper mounting plate 210 and the lower mounting plate 230, the blind holes 520 on the lower mounting plate 230 are aligned with the first guide rod 260 and the second guide rod 290 and allow the first guide rod 260 and the second guide rod 290 to extend into. Thus, both ends of the first guide rod 260 and the second guide rod 290 are respectively fixed in the threaded blind hole 510 and the blind hole 520, thereby preventing the first guide rod 260 and the second guide rod 290 from shifting, and preferably improving the structural stability of the first guide rod 260 and the second guide rod 290 in the groove 130.

[0046] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on one or several embodiments provided by the present application to obtain other embodiments, and these embodiments do not exceed the protection scope of the present application.
