Description

Technical Field

[0001] This utility model relates to the technical field of drone obstacle avoidance training devices, specifically a training device for testing the obstacle avoidance function of drones. Background Technology

[0002] With the rapid development of drone technology, drones are increasingly widely used in logistics, agriculture, surveying, rescue, and other fields. However, the autonomous flight capability of drones in complex environments, especially obstacle avoidance, is crucial for their safe operation. To ensure that drones can effectively identify and avoid obstacles in actual flight, it is necessary to simulate various obstacle scenarios during the training phase to test and optimize their obstacle avoidance algorithms and sensor performance. Traditional drone obstacle avoidance training devices typically use fixed obstacles, which have the following problems: the obstacle positions are fixed and cannot be flexibly adjusted, making it difficult to simulate dynamically changing flight environments; furthermore, existing obstacle structures are usually rigid, which can easily cause damage to the drone's fuselage or propellers upon collision. In addition, some drones identify obstacles through image recognition. For these drones, obstacle avoidance training also requires testing their obstacle avoidance performance against obstacles made of materials with different light properties (reflective properties). Existing obstacles are inconvenient to replace, resulting in low testing efficiency.

[0003] Therefore, there is an urgent need for a drone obstacle avoidance training device that can flexibly adjust the position of obstacles, has a certain buffering capacity, and is easy to replace obstacles. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this invention is to provide a training device for testing the obstacle avoidance function of unmanned aerial vehicles (UAVs). This training device can change the position of simulated obstacles within the training channel, thereby simulating obstacles with different spatial distributions to meet diverse training needs. The obstacle panel is made of fabric and is tensioned and fixed to the inner frame by mounting strips. The flexible material of the obstacle panel not only simulates real obstacles but also provides cushioning in the event of a UAV collision, reducing the risk of equipment damage. The upper and lower ends of the obstacle panel are mounted to the inner frame by mounting strips, allowing for easy replacement of the obstacle panel.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: the training device for testing the obstacle avoidance function of a drone includes a base plate, an obstacle frame, and at least two obstacle curtain panel assemblies.

[0006] The obstacle frame includes two vertical plates and one horizontal plate. The lower ends of the two vertical plates are fixed to the base plate. The two ends of the horizontal plate are respectively connected to the top of the two vertical plates. The vertical plates are provided with through vertical grooves.

[0007] The barrier panel assembly includes a barrier panel, an outer frame, an inner frame, a lifting drive module, and a telescopic drive module. The outer frame includes an outer frame vertical plate and two outer frame horizontal plates. The outer frame vertical plate is slidably disposed within a vertical groove, and each of the two outer frame horizontal plates is provided with a telescopic groove. The upper and lower ends of the inner frame are respectively slidably disposed within the two telescopic grooves. The barrier panel is located within the inner frame.

[0008] A lifting drive module is mounted on the horizontal plate, and the lifting drive module is used to drive the outer frame to slide up and down within the vertical slide groove.

[0009] The telescopic drive module is mounted on the outer frame vertical plate; the telescopic drive module is used to drive the inner frame to telescopically slide in the telescopic groove.

[0010] Furthermore, the lifting drive module includes a lifting drive motor, which is fixed to the horizontal plate. The lower end of the output shaft of the lifting drive motor is connected to a lifting threaded rod, and a lifting threaded sleeve is provided on the outer frame. The lifting threaded rod is located inside the lifting threaded sleeve.

[0011] Furthermore, the telescopic drive motor includes a telescopic drive motor, which is fixed to the outer frame vertical plate. The output shaft of the telescopic drive motor is provided with a telescopic threaded rod, and the inner frame is provided with a telescopic threaded sleeve. The telescopic threaded rod is located inside the telescopic threaded sleeve.

[0012] Furthermore, there are multiple obstacle frames, each of which is an n-shaped frame. Both ends of each obstacle frame are fixed to the base plate, and all obstacle frames are arranged side by side.

[0013] Furthermore, a connecting cover is provided between adjacent obstacle frame bodies, and the front and rear ends of the connecting cover are connected to the obstacle frame body.

[0014] Furthermore, the inner frame includes an inner frame horizontal plate and an inner frame vertical plate. Each inner frame horizontal plate is provided with a sliding mounting groove, and the upper and lower ends of the barrier curtain plate are respectively installed in the sliding mounting groove.

[0015] Furthermore, the barrier panel is made of fabric, and the upper end of the barrier panel is provided with mounting strips. The two mounting strips are respectively installed in the two sliding mounting slots so that the barrier panel is tensioned within the inner frame.

[0016] Furthermore, each mounting strip includes two clamping strips that clamp the ends of the barrier panel.

[0017] Furthermore, the clamping strip is also provided with fastening screws, and the two clamping strips are connected together by the fastening screws.

[0018] Furthermore, the upper and lower ends of the lifting threaded sleeve are respectively fixed to the two outer frame horizontal plates, and the telescopic threaded sleeve is fixed to the inner frame vertical plate.

[0019] The beneficial effects of this utility model's training device for testing the obstacle avoidance function of drones are as follows:

[0020] (1) The obstacle frame of the training device can form a passage for UAVs to pass through. The obstacle frame is equipped with an obstacle curtain assembly including an obstacle curtain, an outer frame, an inner frame, a lifting drive module, and a telescopic drive module. The telescopic drive module can drive the obstacle curtain inside the inner frame to extend into the training passage, and the lifting drive module can adjust the height of the obstacle curtain in the training passage. This allows the position of the simulated obstacles in the training passage to be changed, thereby simulating obstacles with different spatial distributions and meeting diverse training needs.

The mounting strips can be slidably limited in the sliding mounting grooves. This allows the obstacle screen to be easily replaced, so that obstacle screens with different optical properties can be conveniently used to conduct obstacle avoidance training for UAVs.

[0031] Please refer to Figures 1 to 6 The present invention provides a training device for testing the obstacle avoidance function of a drone, comprising a base plate 1, multiple obstacle frame bodies 2, and multiple obstacle curtain panel assemblies.

[0032] The obstacle frame 2 has an n-shaped structure. Both ends of the obstacle frame 2 are fixed to the base plate 1, and all the obstacle frames 2 are arranged side by side. There is a gap between adjacent obstacle frames 2, and a connecting cover 3 is provided between adjacent obstacle frames 2. The front and rear ends of the connecting cover 3 are connected to the obstacle frame 2, thus forming a tunnel-structured training area above the base plate 1. In this embodiment, the obstacle frame 2 at the front is also provided with two door panels 11. The area between the two door panels 11 and extending along the training area is the training area.

[0033] The obstacle frame 2 includes two vertical plates 21 and one horizontal plate 23. The lower ends of the two vertical plates 21 are fixed to the base plate 1. The two ends of the horizontal plate 23 are respectively connected to the top of the two vertical plates 21.

Both the outer frame 6 and the inner frame 7 are C-shaped panels. The outer frame 6 includes an outer frame vertical plate 61 and two outer frame horizontal plates 63. The outer frame vertical plate 61 is slidably disposed in the vertical slide groove 22. The outer frame vertical plate 61 is also provided with lifting limit protrusions 62 on both sides. The two limit protrusions 62 are respectively slidably limited in the two sliding limit grooves on the inner wall of the vertical slide groove 22.

In this embodiment, the obstacle curtain 8 is made of flexible fabric and is tensioned and fixed within the inner frame 7. A telescopic drive module is disposed on the outer frame vertical plate 61; the telescopic drive module is used to drive the outer frame 6 to slide along the telescopic sliding groove 64. When the outer frame 6 slides outward along the telescopic sliding groove 64, the obstacle curtain 8 extends to the training area. A lifting drive module is disposed on the horizontal plate 23; the lifting drive module is used to drive the outer frame 6 to slide up and down within the vertical sliding groove 22, thereby adjusting the height of the obstacle curtain 8.

[0036] When using this training device for testing the obstacle avoidance function of drones, the position of the obstacle curtain 8 in the training area is pre-adjusted through the lifting drive module and the telescopic drive module (i.e., the width of the obstacle curtain 8 extending into the training area and the height of the obstacle curtain 8). Then, the drone flies along the training area and passes through the training area. During the flight, the drone can continue to adjust the position of its obstacle curtain 8 through the lifting drive module and the telescopic drive module, thus simulating obstacles with different spatial distributions to meet diverse training needs.

[0037] The obstacle panel 8 is made of fabric and is tensioned and fixed inside the inner frame 7. The fabric obstacle panel 8 can simulate real obstacles and provide cushioning when the drone collides, reducing the risk of equipment damage.

[0038] In a preferred embodiment, the lifting drive module includes a lifting drive motor 4, which is fixed to the horizontal plate 23. The lower end of the output shaft of the lifting drive motor 4 is connected to a lifting threaded rod 41. A lifting threaded sleeve 42 is provided on the outer frame 6, with the lifting threaded rod 41 located within the lifting threaded sleeve 42. Rotation of the lifting drive motor 4 adjusts the height of the entire outer frame 6. The upper and lower ends of the lifting threaded sleeve 42 are respectively fixed to the two outer frame horizontal plates 63.

[0039] The telescopic drive module includes a telescopic drive motor 5, which is fixed to the outer frame vertical plate 61.

By rotating the telescopic drive motor 5, the length of the entire inner frame 7 relative to the outer frame 6 can be adjusted. The telescopic threaded sleeve 52 is fixed to the inner frame vertical plate 71 and passes through the inner frame vertical plate 71.

[0040] As can be seen from the above, the lifting drive motor 4 and the telescopic drive motor 5 can respectively control the telescopic length and vertical position of the barrier panel 8. The control process and control system of the lifting drive motor 4 and the telescopic drive motor 5 are existing technologies, and their structure and principles will not be described in detail here.

[0041] In a preferred embodiment, the inner frame 7 includes two inner frame horizontal plates 72 and an inner frame vertical plate 71. Each inner frame horizontal plate 72 is provided with a sliding mounting groove 73, and the upper and lower ends of the barrier curtain plate 8 are respectively installed in the sliding mounting groove 73.

[0042] The barrier panel 8 is provided with mounting strips at its upper end. The two mounting strips are respectively installed in the two sliding mounting grooves 73 to tension and fix the barrier panel 8 within the inner frame 7. Specifically, each mounting strip includes two clamping strips 81, which clamp the end of the barrier panel 8. The two clamping strips 81 are also provided with threaded holes, and fastening screws are provided in the threaded holes. The two clamping strips 81 are fixedly connected together, thereby clamping and fixing the end of the barrier panel 8.

[0043] The obstacle panel 8 is fixed at the top and bottom by mounting strips, and the structure of the sliding mounting strips in the sliding mounting groove 73 allows the obstacle panel 8 to be easily replaced. The obstacle panel 8 can be made of fabrics with different optical properties, such as reflective cloth or transparent curtain. This makes it convenient to use obstacle panels 8 with different optical properties to conduct obstacle avoidance training for drones.
