Problems solved by technology
At present, there is no special equipment to test the performance of drones, only through flight tests, which requires a large airspace and reduces safety
[0004] (1) In actual operation, drones need to fly in different environments, so the detection of drones needs to be tested at high temperature, low temperature and different wind speeds. It is necessary to set up a large high and low greenhouse, which is costly;
[0005] (2) Flying tasks in a limited space are relatively narrow, and it is easy to cause collisions and damage the fuselage

Embodiment Construction
[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0034] Such as figure 1 A test bench test system for unmanned aerial vehicles shown, including the unmanned aerial vehicle under test 1, the load-bearing unmanned aerial vehicle end 2, the connecting shaft 3, the transmission four-bar linkage 4, the measuring weight end 5 (including the mass block ), the ground support seat 6 can be used for unmanned helicopter inspection and detection, and can realize high-precision and high-reliability inspection and detection with equipment such as force sensors and speed sensors.
[0035] The device adopts a parallel four-bar linkage mechanism, and the angular velocity is kept consistent. The connecting rod always moves in translation. Using this feature, the device can make parallel and synchronous movements during the movement process, so as to achieve the unhindered and flexible movement of the UAV, and ensure th...

The invention discloses an unmanned aerial vehicle (UAV) test bed system for inspection and detection, comprising a bearing UAV end, a ground supporting seat, a transmission mechanism, and a weight measuring end. The bearing UAV end is used for bearing an object to be tested, and is connected with one end of the transmission mechanism through a connecting shaft. The other end of the transmission mechanism is provided with the weight measuring end. The weight measuring end is provided with a mass block. The ground supporting seat is arranged on the transmission mechanism. During test, the angular speed of rotation of the transmission mechanism is kept consistent, and the transmission mechanism always moves in a translational manner, so that the test bed system does parallel and synchronous movement in the process of movement, and flexible and barrier-free movement of the UAV is achieved. According to the invention, a parallel four-bar mechanism is adopted to make level for the tested UAV, and a weight at the end is changed and adjusted in real time according to the weight of the tested object. The test bed does not need to be fixed to the ground, and universal wheels are adopted to make movement and transportation convenient.
Description
technical field [0001] The invention relates to an unmanned aerial vehicle test bench system for inspection and detection. Background technique [0002] Unmanned helicopters have been vigorously developed in civilian fields such as electric power, geological surveys, and agriculture. Unmanned helicopters carry pods, pesticide spraying systems, etc., which can ensure that tasks required in various fields are performed at an appropriate time and power inspections are completed in a timely manner. , geological survey, pesticide spraying and other tasks. [0003] UAVs have become the development focus of future civilian operations. In order to ensure the performance of UAVs used in various fields is qualified, it is bound to become a key point to test the performance indicators of UAVs. At present, there is no special equipment to test the performance of UAVs, only through flight tests, which requires a large airspace and reduces safety. [0004] (1) In actual operation, drone...
