[0003] Existing commonly used drones, due to size limitations and technical reasons, almost all use non-omnidirectional obstacle avoidance, usually using forward, downward, and backward obstacle avoidance, which can create flight safety hazards in the upward, left, and right directions. Users may encounter collisions in these directions when flying drones, leading to crashes. Utility Model Content

Detailed implementation

[0029] To make the objectives, technical solutions, and advantages of the present technical solution clearer, the present technical solution will be further described in detail below in conjunction with specific implementation manners. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present technical solution.

[0030] To solve the problem in the prior art that during the flight of a UAV, collisions may occur in some directions without vision modules, resulting in crashes, this embodiment proposes an omnidirectional obstacle avoidance structure for a UAV. This omnidirectional obstacle avoidance structure mainly cooperates with multiple vision brackets and vision modules to achieve visual recognition in multiple directions such as the front, back, up, down, left, and right of the UAV, and thus achieve the omnidirectional obstacle avoidance function.

[0031] Specifically, as Figure 1 and Figure 2 shown, the omnidirectional obstacle avoidance structure of the UAV includes a front vision bracket 1. The front vision bracket 1 is generally in a "one" - shaped or "bow" - shaped structure. The width of the front vision bracket 1 is generally the same as the width of the UAV fuselage 5. The front vision module 2 includes two camera modules, and the two camera modules are respectively located at the left and right ends of the front vision bracket 1.

[0032] The omnidirectional vision bracket 3 is in a "U" - shaped structure. The omnidirectional vision bracket 3 includes a cross beam 31 and two side beams 32 connected to the two ends of the cross beam 31. The cross beam 31 is located at the rear side of the top surface of the UAV fuselage 5, and the side beams 32 are located at the side of the top surface of the UAV fuselage 5. Among them, the side beam 32 includes two first mounting positions 33 opened laterally. One of the first mounting positions 33 is located at the free end of the side beam 32, and the other first mounting position 33 is located in the middle of the side beam 32. The middle of the side beam 32 also includes a second mounting position 34 opened upward. The cross beam 31 includes two third mounting positions 35 opened backward, and the third mounting positions 35 are adjacent to the connection between the cross beam 31 and the side beam 32. The omnidirectional vision module 4 includes 8 single - body camera modules, and the 8 camera modules are respectively installed in the corresponding 4 first mounting positions 33, 2 second mounting positions 34, and 2 third mounting positions 35.

[0033] The lower vision bracket 6 is generally in a "day" - shaped structure, and there is a mounting position at the front and rear parts of the lower vision bracket 6, and each mounting position installs a camera module.

[0034] The front vision module 2, multi-directional vision module 4 and lower vision module 7 have a total of 12 camera modules. Each vision module is installed at the end of the rod of the frame or the end of the frame, which has the advantage of obtaining a wide viewing angle.

[0035] like Figure 2 As shown, the front vision bracket 1 is installed at the front of the drone body 5; the multi-directional vision bracket 3 is installed on the top of the drone body; and the lower vision bracket 6 is installed at the lower part of the drone body 5. At the same time, the front vision bracket 1, the multi-directional vision bracket 3 and the lower vision bracket 6 are detachably connected to the drone body 5 by screws. This makes it convenient to maintain and disassemble the front vision bracket 1, the multi-directional vision bracket 3 and the lower vision bracket 6, and to replace the corresponding camera module. The front vision bracket 1, the multi-directional vision bracket 3 and the lower vision bracket 6 all have a hole-shaped mounting position for installing a camera module unit. After the camera module unit is inserted into the hole-shaped mounting position, it is bonded to the surrounding structural parts. This connection method has an anti-fool effect and is more convenient to install and disassemble.

[0036] like Figure 1 As shown, the front vision bracket 1, the multi-directional vision bracket 3 and the lower vision bracket 6 all have weight-reducing hollows or weight-reducing grooves to achieve the effect of reducing the load of the drone.

[0037] This omnidirectional obstacle avoidance structure adopts multiple groups of camera modules integrated on the front vision bracket 1, the multi-directional vision bracket 3 and the lower vision bracket 6. Different groups of camera modules are respectively facing multiple directions of the fuselage. Each bracket is equipped with a binocular vision module, which can enable the drone to achieve omnidirectional obstacle avoidance function in all directions. Even in complex environments, the drone can still perform visual recognition through the camera module and can still fly safely and autonomously, greatly increasing the flight safety performance of the drone.

[0038] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
