DETAILED DESCRIPTION

[0021] The present application will be further described below with reference to the accompanying drawings.

[0022] Example 1

[0023] Please see Figures 1-5 , the present application is a kind of unmanned aerial vehicle direction management anti-collision ranging mechanism, including body 1, body 1 bottom side wall and close to two side edges It is fixedly connected with support leg 3, support leg 3 is conical structure, body 1 four corners and close to top edge It is fixedly connected with support arm 2, support arm 2 away from body 1 top side wall of one end of the fixed connection has propeller, body 1 bottom side wall middle fixedly connected with detection box 4, detection box 4 Four side walls in the middle are all through the through hole 5, each through hole 5 It is inserted with detection head 6, detection box 4 away from body 1 The bottom side wall in the middle is embeddedly connected with range finder 7, detection box 4 Bottom and located on both sides of range finder 7 The side wall is all through the bottom groove 8, each bottom groove 8 It is opposite to the two side walls and is provided with side groove 9 in, side groove 9 It is slidably connected with moving block 10, moving block 10 The bottom side wall in the middle is embeddedly connected with auxiliary range finder 11.

[0024] By setting a detection head 6 around the detection box 4 can timely detect the obstacles around the body 1, avoid the body 1 and the obstacle distance too close to occur flat and cause the body 1 damage, because set up four detection heads 6 So can timely adjust the direction and height of body 1 flight according to actual situation, effectively improve the flexibility of body 1 ranging and obstacle avoidance.

[0025] The distance between the body 1 and the ground can be detected by the established range finder 7. Because the flight height of the body 1 is limited, especially for industrial use, the flight height is not high due to the influence of weight, and when avoiding obstacles, it is mainly to descend to avoid. Therefore, the ground range finder 7 needs to be set up, and in cooperation with the two movable auxiliary range heads 11, the two sides centered on the range finder 7 can be detected. Because the auxiliary range head 11 can move, dynamic detection can be performed. Because the ground sometimes has a concave valley terrain, it will cause the distance between the body 1 and the ground to be inaccurate, and the descending body 1 will collide with the ground. Through the two auxiliary range heads 11, the surrounding ground can be measured to assist in measuring the data to determine the general terrain, so as to make a proper judgment to avoid the body 1 from colliding with the ground due to judgment errors.

[0026] Through the above technical solution, the obstacles around the body 1 can be effectively ranged, and the effectiveness of obstacle avoidance ranging and the flexibility of adjustment can be effectively improved. Via the established range finder 7 and auxiliary range head 11, the terrain of the ground can be roughly detected and judged to avoid damage to the body 1 due to incomplete data and landing. Through the auxiliary range head 11 and the range finder 7, simple terrain mapping work can also be achieved.

[0027] Embodiment two

[0028] Please refer to Figures 2-4 As shown in the figure, the detection box 4 is provided with an inner groove 12. The inner groove 12 is provided with a motor 18 detachably connected to the middle of the top side wall through a screw. The output end of the motor 18 is fixedly connected with a main shaft 19. The main shaft 19 is provided with two driving gears 20. One of the driving gears 20 is meshingly connected with a bevel gear 14 on the four sides of the bottom. The bevel gear 14 is fixedly connected with a No. 2 threaded rod 15 in the middle of the side wall away from the main shaft 19. The No. 2 threaded rod 15 is provided with a sleeve rod 16 at the end away from the bevel gear 14. One end of the sleeve rod 16 is telescopically inserted into the through hole 5. The probe head 6 is detachably connected to the end of the sleeve rod 16 away from the No. 2 threaded rod 15. The No. 2 threaded rod 15 is threadedly connected in the sleeve rod 16. The sleeve rod 16 and the No. 2 threaded rod 15 are sleeved with a boom 17 at one end. The boom 17 is fixedly connected to the top side wall in the inner groove 12 through the top end.

[0029] When it is needed to extend the probe head 6 from the detection box 4, the motor 18 is started to drive the main shaft 19 to rotate, which drives the four bevel gears 14 to rotate via the synchronously rotating driving gears 20, and finally drives the second threaded rod 15 to rotate, which drives the movement of the sleeve rod 16 via the threaded connection, and finally realizes the function of driving the probe head 6 to extend and retract. Since the probe head 6 is extended from the detection box 4, the distance between the probe head 6 and the obstacle can be shortened, so that the distance between the obstacle and the machine body 1 can be determined earlier. Since the probe head 6 moves away from the machine body 1, a certain distance can be added to the originally set dangerous distance, so that the distance between the machine body 1 and the obstacle is increased, and more reaction time is left for the staff to adjust the machine body 1 in time, thereby improving the obstacle avoidance efficiency.

[0030] By sleeving a hanger 17 on the second threaded rod 15 and the sleeve rod 16, the sleeve rod 16 and the second threaded rod 15 can be kept in a stable horizontal state without affecting their normal operation.

[0031] Through the above technical scheme, a certain buffer distance can be added to the original dangerous distance, so that enough reaction time is left for the staff, and the collision and damage of the machine body 1 with the obstacle caused by insufficient reaction and failure to control the machine body 1 to avoid obstacles in time can be avoided.

[0032] Embodiment Three

[0033] Please refer to Figures 2-4 As shown in the figure, two bottom grooves 8 are threadedly connected to the first threaded rods 13 at one end of the middle of the inner groove 12. One end of the first threaded rods 13 is rotatably connected to the two side walls in the inner groove 12, and the two first threaded rods 13 are located below the second threaded rod 15. The ends of the two first threaded rods 13 close to the range finder 7 are fixedly connected with the bevel gears 14. The two bevel gears 14 are meshingly connected with the driving gears 20 at the top and the bottom. The two side walls of each moving block 10 away from each other and opposite to the side grooves 9 are fixedly connected with the moving blocks 10, and the moving blocks 10 are slidably connected in the side grooves 9.

[0034] Since the motor 18 is started to drive the main shaft 19 to rotate, the two driving gears 20 are synchronously rotated. The driving gears 20 at the bottom drive the two bevel gears 14 meshingly connected thereto to synchronously rotate, thereby driving the corresponding two first threaded rods 13 to rotate, which drives the moving blocks 10 to move along the bottom grooves 8 via the threaded connection, thereby driving the corresponding two auxiliary probe heads 11 to synchronously move. By controlling the movement of the two auxiliary probe heads 11, the two sides of the measurement point of the range finder 7 can be scanned and measured, thereby realizing the function of range detection, and improving the measurement accuracy.

[0035] In order to ensure the stability of the movement of the moving block 10, one moving block 10 is fixedly connected on both sides of the moving block 10, and the moving block 10 moves in the side slot 9, so as to avoid the deviation of the moving block 10 during the movement, thereby causing the inaccuracy of the measured data.

[0036] Through the above technical scheme, the two moving auxiliary ranging heads 11 and the static range finder 7 are matched with each other, so that the comprehensiveness and accuracy of detection can be effectively improved, and the collision between the machine body 1 and the obstacle caused by the judgment error of the staff due to too much reliance on the detection data can be avoided.

[0037] Embodiment Four

[0038] Please refer to Figures 4-5 As shown in the figure, four sliding grooves 23 are evenly arranged on the side walls near the two ends of the main shaft 19, two driving gears 20 are telescopically connected to the main shaft 19, four sliding blocks 24 are fixedly connected to the inner wall of the middle ring of the driving gear 20, the sliding blocks 24 are slidingly connected in the corresponding sliding grooves 23, four connecting blocks 22 are fixedly connected to the middle side of the main shaft 19, one telescopic rod 21 is embeddedly connected to one end of each connecting block 22 away from the main shaft 19, every two corresponding telescopic rods 21 are arranged, the output ends of the four telescopic rods 21 are opposite to each other, and the output ends of the four telescopic rods 21 are fixedly connected to the side walls of the two driving gears 20, respectively.

[0039] Because sometimes the detection head 6 or the auxiliary ranging head 11 needs to be moved alone, because the two driving gears 20 are arranged in a movable form, when only the detection head 6 needs to be telescopically moved, the two telescopic rods 21 connected to the driving gear 20 located below are started, so as to lift the corresponding driving gear 20 upward, thereby disconnecting the corresponding driving gear 20 from the corresponding bevel gear 14, so that when the motor 18 is started, only the driving gear 20 located above and the corresponding four bevel gears 14 can be driven to rotate, and finally the detection head 6 is driven to move, when the moving block 10 needs to be moved alone, the other two telescopic rods 21 are started to lift the driving gear 20 close to the motor 18, only the driving gear 20 located below is connected to the bevel gear 14, so as to realize the function of driving the moving block 10 to move alone, and when the two need to be moved synchronously, the two driving gears 20 are adjusted to be connected to the corresponding bevel gears 14.

[0040] In order to ensure the stability of the driving of the telescopic rod 21 to the driving gear 20, and at the same time avoid the influence of the telescopic rod 21 on the main shaft 19, the telescopic rod 21 is fixed to the side wall of the main shaft 19 through the connecting block 22, so that the telescopic rod 21 can rotate synchronously with the main shaft 19, thereby realizing the function of synchronous operation of the driving gear 20.

[0041] Through the technical scheme, the probe head 6 or the moving block 10 can be driven individually according to the requirement, thereby improving the flexibility of application and the strain capacity of the body 1 during flight.

[0042] The control center is installed at one corner of the detection box 4, and the electronic devices for controlling the start and stop of the motor 18, receiving measurement data and giving an alarm are integrated in the control center. Since the control mode and the distance determination mode are in the form of conventional electronic signals, no further description is given herein. It is additionally pointed out that the motor 18 is a structure capable of being reversely rotated under the control of the control center.

[0043] The above is only the preferred embodiment of the present application, and it should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.

[0044] The other parts not described in detail in the present application are all prior art, and thus no further description is given herein.

[0045] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
