Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a flight obstacle alarm device for UAVs. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and onboard program control devices. While they lack a cockpit, they are equipped with autopilots, program control devices, etc. During flight, UAVs encounter many obstacles, such as buildings, flying birds, and tree branches. Because operators are on the ground, errors in distance perception due to human eyes can easily lead to collisions with obstacles, causing wing damage and crashes, thus increasing the cost of UAV operation.

[0005] In embodiments of this utility model, the number of wings is at least four, and the number of wings is equal to the number of baffles.

[0006] In an embodiment of this utility model, the operating box is provided with a plurality of fixed boxes, the same number as the telescopic rod, one end of the telescopic rod is fixedly installed inside the fixed box, and the other end of the telescopic rod is fixed to the baffle.

[0007] In an embodiment of this utility model, the baffle is arc-shaped and located on the outside of the wing.

[0008] In an embodiment of this utility model, a stop block is provided on the outside of the support rod, and the two ends of the spring abut against the stop block and the operating box respectively.

[0009] In an embodiment of this utility model, one end of the support rod is fixed to the baffle, and the other end of the support rod is fixed with a top block. The top block is spherical and made of rubber.

[0010] In an embodiment of this utility model, the number of support rods is twice the number of telescopic rods, and the telescopic rods are located in the middle of the two support rods.

[0011] In an embodiment of this utility model, the outside of the operation box is provided with a plurality of fixing holes, the number of fixing holes being the same as the number of support rods, and the support rods being slidably connected to the fixing holes.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please refer to Figures 1-2. This utility model provides a technical solution: a flight obstacle alarm device for a drone, including a body 10 and multiple wings 1001 disposed on the body 10. An operation box 20 is disposed on the body 10, with multiple support rods 21 and multiple telescopic rods 2002 disposed on the operation box 20. Multiple baffles 2003 are disposed on the outer periphery of the operation box 20, the number of baffles 2003 being equal to the number of telescopic rods 2002. A control box 2004 is disposed inside the operation box 20, with an alarm 2005 disposed on the control box 2004. The control box 2004 and the alarm 2005 are electrically connected. The alarm 2005 is communicatively connected to the drone's remote control, and the alarm signal emitted by the alarm 2005 can be fed back to the screen of the drone's remote control to remind the operator. The specific connection method and working principle are already disclosed in the prior art and will not be described in detail in this technical solution.

[0022] In this embodiment, the number of wings 1001 is at least four, and the number of wings 1001 is equal to the number of baffles 2003.

[0023] The control box 20 has multiple fixed boxes 2001, the same number as the telescopic rod 2002, inside. One end of the telescopic rod 2002 is fixedly installed inside the fixed box 2001, and the other end of the telescopic rod 2002 is fixed to the baffle 2003. The telescopic rod 2002 supports the baffle 2003. When the baffle 2003 is squeezed, the telescopic rod 2002 moves with it.

[0024] Meanwhile, the baffle 2003 has an arc-shaped design and is located outside the wing 1001. The baffle 2003 surrounds the wing 1001, which can prevent the wing 1001 from colliding with obstacles and causing damage to the wing 1001.

[0025] Please see Figure 3The control box 20 is equipped with multiple support rods 21, and springs 2102 are sleeved on the outside of the support rods 21. When the baffle 2003 is squeezed, the support rods 21 move into the control box 20, and the springs 2102 are squeezed. The control box 20 is equipped with a connector 2104, and a push plate 2105 is provided on the connector 2104. A contact plate 2106 is provided on one side of the push plate 2105. The control box 20 is equipped with multiple sensors 2107. The sensors 2107 are electrically connected to the control box 2004. When the contact plate 2106 is in contact with the sensors 2107, the sensors 2107 transmit the received signals to the control box 2004. After receiving the signals, the control box 2004 activates the alarm 2005. The alarm 2005 can remind the operator to change the flight path of the UAV in time to avoid the UAV from colliding with obstacles and causing damage to the wings 1001.

[0026] In this embodiment, a stop 2101 is provided on the outside of the support rod 21, and the two ends of the spring 2102 abut against the stop 2101 and the operation box 20 respectively.

[0027] It should be noted that one end of the support rod 21 is fixed to the baffle 2003, and the other end of the support rod 21 is fixed with a top block 2103. The top block 2103 is spherical and made of rubber. When the support rod 21 moves into the control box 20, the top block 2103 presses the push plate 2105 to rotate. During the rotation, the push plate 2105 drives the contact plate 2106 to contact the sensing sensor 2107.

[0028] In addition, the number of support rods 21 is twice the number of telescopic rods 2002. The telescopic rods 2002 are located in the middle of the two support rods 21. The support rods 21 can further improve the support effect on the baffle 2003, making the baffle 2003 more stable.

[0029] It is understandable that the operation box 20 has multiple fixing holes on its exterior, the number of which is the same as the number of support rods 21. The support rods 21 are slidably connected to the fixing holes. The diameter of the stop block 2101 is larger than the diameter of the fixing hole, so the stop block 2101 cannot be moved out of the operation box 20.

[0030] It should be emphasized that the connector 2104 is fixedly installed on one side of the fixed box 2001, and the push plate 2105 is rotatably connected to the connector 2104.

[0031] Finally, the sensing sensor 2107 is fixedly installed on the top of the fixed box 2001. The number of sensing sensors 2107 is equal to the number of contact plates 2106. The side of the sensing sensor 2107 closest to the contact plate 2106 is designed with a bevel. The model of the sensing sensor 2107 may include, but is not limited to, one of JC-TM803, GT-71A, and GT-A10.

[0032] Specifically, the working principle of this drone flight obstacle warning device is as follows: When an operator is controlling a drone to fly, if the drone fails to avoid an obstacle due to misjudgment, the baffle 2003 will first come into contact with and be squeezed by the obstacle as the drone continues to approach it. After being squeezed, the baffle 2003 pushes the support rod 21 to move into the control box 20. The top block 2103 squeezes the push plate 2105 to rotate. During the rotation of the push plate 2105, the contact plate 2106 comes into contact with the sensing sensor 2107. When the contact plate 2106 and the sensing sensor 2107 are in contact, the sensing sensor 2107 transmits the received signal to the control box 2004. After receiving the signal, the control box 2004 activates the alarm 2005. The alarm 2005 sends an alarm signal to the screen of the operator's remote control, which can remind the operator to change the drone's flight path in time to avoid the drone colliding with the obstacle and causing damage to the wing 1001 and crashing.

[0033] It should be noted that the specific models and specifications of the control box 2004, alarm 2005, contact plate 2106, and sensor 2107 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0034] The power supply and operating principle of the control box 2004, alarm 2005, and sensor 2107 are clear to those skilled in the art and will not be described in detail here.
