Description

A drone battery replacement device

technical field

The utility model relates to a novel economical and efficient unmanned aerial vehicle charging pile hardware device, in particular to an unmanned aerial vehicle battery replacement device.

Background technique

Nowadays, the application of drones is more and more extensive all over the world. It is used in aerial survey and reporting, food crop management, real estate evaluation, sports photography, express delivery and many other fields. However, due to the problem of the battery life of the current drones (the battery life of the current drones is about 30 minutes), its application is mostly limited to small-scale attempts and short-term work. This leads to an external battery weighing about half a catty. Although it can meet the needs of some aerial photography, it cannot play a good role in natural disasters and on-site disaster relief due to battery life problems. Even Amazon's delivery drones can only cover a few kilometers around warehouses. Therefore, many countries and companies in the world are now investing in the construction of half-way charging devices specially used for drones.

However, most of the existing drone charging piles use the pure charging mode, that is, the drones that are short of power need to wait for a long time in the charging pile before they can complete charging. Even non-battery UAVs need to wait for a long time at a fixed location before continuing to sail.

Most of the existing UAV charging piles are very complicated charging structures, resulting in the construction of each charging device requires a lot of cost. At the same time, if the charging equipment of the charging pile is damaged in some places, the entire charging pile will be unusable. In addition, due to the high construction cost of existing UAV charging piles, it is impossible to build multiple charging piles in a large area, which also greatly limits the working range of UAVs.

Utility model content

The technical problem to be solved by the utility model is to provide a battery replacement device for drones, which can complete charging more quickly, that is, replace the battery; when dealing with emergencies, it can quickly replenish the battery and return to processing when the battery is insufficient. In case of emergency, its overall design is relatively simple, occupies a small area, and is easy to produce.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A battery replacement device for an unmanned aerial vehicle, including a positioning and clamping part, a battery loading and unloading part and a manipulator arranged in sequence;

Both ends of the first moving guide rail and the second moving guide rail are fixed with sliders, and the sliders are installed on the first fixed guide rail and the second fixed guide rail;

A first push plate that can move along it is arranged on the first moving guide rail, and a second push plate that can move along it is arranged on the second moving guide rail;

The structure of the battery loading and unloading part is as follows: the fourth motor is fixed on the frame, the fourth motor is connected to a shaft, the shaft passes through a bearing, and a top plate is fixed on the bearing.

Further, the structure of the manipulator is: the finger, the small arm, the middle arm, and the large arm are flexibly connected in sequence;

A boom rotating gear is arranged on the bottom plate, and the boom rotating gear is connected to the third motor; a boom fixed gear is fixed on the boom, and the boom fixed gear meshes with the boom rotating gear;

The middle arm rotating gear is also arranged on the big arm, and the middle arm rotating gear is connected to the second motor, and the middle arm fixed gear is fixed on the middle arm; the middle arm fixed gear meshes with the middle arm rotating gear;

A small arm gear is coaxially fixed on the connecting rod between the small arm and the middle arm; the small arm gear is sequentially connected with the chain and the first motor.

Further, crawler belts are also provided, and the crawler belts are arranged at the bottom of the bottom plate.

Further, there are four crawlers.

Compared with the prior art, the beneficial effect of the utility model is that the charging can be completed more quickly, so that when dealing with an emergency, the battery can be replenished faster and returned to deal with the emergency after encountering insufficient charge. At the same time, the charging pile can provide more comprehensive information to the drones performing operations, allowing the drones to choose comprehensively for charging. In addition, the overall design of the charging pile is relatively simple, occupies a small area, is easy to produce, and does not require high production technology. It can be produced more in a certain area to make the application of drones more extensive.
