Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, provide a tripod structure that can realize the deployment and retraction of the tripod of the drone, and solve the problem of unmanned aerial vehicles when the tripod is not put into use. The large footprint of the drone also avoids the risk of damage to the drone during storage

Embodiment 1

[0030] Such as figure 1 and image 3 As shown, a tripod structure using three-axis gear opening and closing described in this embodiment is used for drones, including a bracket 1, a transmission mechanism 2 and a tripod 3, and the bracket 1 is connected to the drone on the one hand. On the other hand, as the installation base of the transmission mechanism 2, it is connected to the tripod 3 through the tripod shaft 301 at the end, and the tripod and the UAV are connected. The transmission mechanism 2 is the key structure of the tripod structure. The transmission mechanism 2 is driven by a motor 201. An output gear 202 is provided at one end of the drive source. The output gear 202 meshes with the transmission gear 203, and the transmission gear 203 meshes with the input gear 204. The gear 204 is connected to the tripod 3 through the tripod shaft 301, thereby realizing the power output and driving of the tripod 3, and the rotation of the motor 201 controls the tripod 3 to open ...

Embodiment 2

[0035] Such as figure 2As shown, it is a tripod structure that utilizes a gear set to open and close. The difference between this embodiment and the first embodiment above is that the transmission mechanism 2 includes one or more transmission gears 203 . When there are multiple transmission gears 203, the multiple transmission gears 203 are sequentially engaged and connected to realize power transmission. Compared with the first embodiment, the advantage of this embodiment is that the design of multiple transmission gears makes the process of power transmission smoother, avoiding the failure of the tripod that may be caused by excessive power.

Embodiment 3

[0037] Not shown in the figure, this embodiment is a further limitation of the above embodiment, the tripod structure is provided with a limit mechanism, the limit mechanism is used to monitor the opening or closing angle of the tripod, and communicate with the drone By transmitting the monitored information, the UAV can judge whether the opening and closing of the tripod 3 is in place through the monitored angle information, so as to control the rotation or stop of the motor 201 . The limit mechanism can be set on the motor 201 to monitor the number of rotations of the motor 201 ; or it can be set on the gear to monitor the number of rotations of the gear; or it can be set on the tripod shaft 301 .

Abstract

The invention discloses a tripod structure opened and closed by a gear set. The tripod structure comprises a bracket fixed on an unmanned aerial vehicle (UAV) body, a tripod connected with the bracket by a tripod rotating shaft, and a transmission mechanism arranged between the bracket and the tripod, wherein the transmission mechanism comprises a motor fixed on the bracket, an output gear fixedly connected with a motor shaft, an input gear arranged coaxially with the tripod rotating shaft, and at least one transmission gear arranged between the output gear and the input gear. The tripod structure provided by the invention adopts the motor and the gear set to control opening and closing of a UAV tripod; when a UAV is not put into use, a gear set transmission mechanism can control the tripod to be retracted into a machine body or attached to a surface of the machine body, thereby reducing the volume and the occupied area of the UAV and facilitating storage of the UAV.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles, and relates to an unmanned aerial vehicle whose tripod can be opened and closed automatically, in particular to a tripod structure which utilizes a gear set to open and close. Background technique [0002] UAV, also known as unmanned aerial vehicle, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. It is a high-tech product integrating aerodynamics, material mechanics, automatic control technology, and software technology. . UAVs are widely used in many fields such as aerial photography, surveillance, investigation, search and rescue due to their flexible actions, low requirements for take-off and landing environments, and good operational performance. This kind of drone generally has a tripod, so that when the drone lands, it can stand and support the aircraft through its tripod. [0003] However, the existing unmanned aerial vehicl...
