DETAILED DESCRIPTION

[0029] See also Figure 1-Figure 10 In an embodiment of the present invention, a motion camera device for a drone includes a drone body 1, a camera assembly is installed at the bottom of the drone body 1, and a first leg 2 for supporting the drone body 1 is also installed at the bottom of the drone body 1; a trigger assembly is rotatably installed at the bottom of the first leg 2, a protective assembly is fixedly installed at the bottom of the drone body 1, and the protective assembly is arranged at the periphery of the camera assembly, a transmission assembly is arranged in the drone body 1, and the trigger assembly is connected to the camera assembly through the transmission assembly. When in use, when the drone body 1 encounters other obstacles such as trees or cables during flight, the drone body 1 cannot avoid them in time. At this time, the trigger assembly will contact the obstacle through the set trigger assembly, and then relatively rotate on the first leg 2. When the trigger assembly rotates on the first leg 2, the trigger assembly will drive the camera assembly to move toward the drone body 1 through the transmission assembly, and the camera assembly will be in the protective assembly after moving upward, so that the protective assembly provides protection for the camera assembly, avoiding the problem of damage to the camera assembly caused by collision between the camera assembly and the obstacle.

[0030] See also Figure 1-Figure 2 , Figure 4Preferably, the trigger assembly includes a second leg 3; a groove 18 is provided on the top of the second leg 3, and a protrusion slidably fitted with the groove 18 is provided at the bottom of the first leg 2, and first arc edges 22 are provided on both sides of the bottom of the protrusion, so as to facilitate the second leg 3 to rotate on the first leg 2, and the top of the second leg 3 is rotatably connected to the bottom end of the first leg 2, and a torsion spring is provided at the rotation connection between the second leg 3 and the first leg 2. Through the setting of the torsion spring, the second leg 3 always keeps level with the first leg 2 when there is no external force, so as to maintain stability when the drone body 1 is landing, and four groups of first legs 2 are provided along the four corners of the bottom of the drone body 1.

[0031] See also Figure 1-Figure 7 Preferably, a second pull rope 15 is fixedly provided at the bottom of the groove 18 away from the first leg 2, and one end of the second pull rope 15 away from the groove 18 slides through the protrusion and the side wall of the first leg 2 and is connected to the transmission assembly. When there is an obstacle at the bottom of the drone body 1 during flight, the obstacle will come into contact with the second leg 3. Then, as the drone body 1 continues to fly forward, the second leg 3 will rotate along the first leg 2 under the action of the obstacle. After the second leg 3 rotates, due to the rotation connection between the second leg 3 and the first leg 2 The contact point is at the bottom end of the first leg 2, and the bottom of the second pull rope 15 is fixed at the bottom of the groove 18, so the rotation of the second leg 3 will pull the second pull rope 15 away from the first leg 2, thereby driving the transmission assembly to rotate through the second pull rope 15, and then the camera assembly moves upward and shrinks in the protective assembly, avoiding the problem of damage to the camera assembly caused by collision with obstacles. After the drone body 1 passes over the obstacle, the second leg 3 rotates and resets under the action of the torsion spring, and then the camera assembly also moves downward and resets, so as to continue working.

[0032] See also Figure 4-Figure 5 , Figure 8 , Fig. 9Preferably, in order to prevent the second legs 3 from rotating during the landing of the drone body 1, which may cause the drone body 1 to be unable to land stably, a bottom plate 4 is fixedly provided at the bottom of the second legs 3. It should be noted that a group of bottom plates 4 is provided between the two horizontally opposite groups of second legs 3, and two groups of bottom plates 4 are provided, and the bottom plates 4 correspond to the forward and backward directions of the drone body 1. In this way, when the drone body 1 flies forward, protection can be provided for the camera assembly. A sliding bar is provided in the bottom plate 4 through spring elastic sliding. 17, the sliding bar 17 is in a state of protruding from the bottom of the bottom plate 4 when the drone body 1 is flying, so that when the drone body 1 lands, the sliding bar 17 will first contact the ground and then move upward, and a limit plate 16 is fixedly arranged on the top of the sliding bar 17, and the limit plate 16 is slidably arranged on the inner wall of the second leg 3, and when the sliding bar 17 moves upward, the limit plate 16 will move upward; a limit key 19 is arranged on the top of the limit plate 16, and the limit plate 16 moves upward to push the limit key 19 to move upward, and the limit key 19 moves along the limit plate 1 The center of 6 is symmetrically arranged, the top ends of the limit key 19 are chamfered, the bottom of the protrusion is provided with a limit hole 20 that is slidably adapted to the limit key 19, and the two sides of the opening of the limit hole 20 are provided with second arc edges corresponding to the chamfers on the limit key 19, so that when the limit key 19 moves upward, the limit key 19 can be more easily inserted into the limit hole 20 to complete the limit between the first leg 2 and the second leg 3, avoiding the problem that the second leg 3 may rotate when the drone body 1 is landing, and ensuring the stability of the landing of the drone body 1. The top of the limit plate 16 is provided with a fitting portion 25 which slidably cooperates with the first arc edge 22 at the bottom of the protrusion. After the limit plate 16 moves upward, the fitting portion 25 can make the top of the limit plate 16 tightly slidably cooperate with the bottom of the protrusion. When the fitting portion 25 is adapted to the first arc edge 22 at the bottom of the protrusion, combined with the action of the limit key 19 and the limit hole 20, firstly, there is better stability between the first leg 2 and the second leg 3, and secondly, the problem of damage to the limit key 19 which may occur when limiting by the limit key 19 alone is avoided.

[0033] See also Figure 1-Figure 3 , Figure 6 , Fig.10Preferably, the protective assembly includes a protective shell 5; the top of the protective shell 5 is arranged at the bottom center of the drone body 1, and the protective shell 5 is arranged on the periphery of the camera assembly; an air cavity 9 is arranged at the bottom of the drone body 1, and the camera assembly is slidably mounted on the drone body 1 through the air cavity 9. When the second leg 3 rotates, the camera assembly is moved upward and retracted in the protective shell 5 through the transmission assembly, so that the camera assembly is protected by the protective shell 5 to avoid the problem of damage to the camera assembly caused by collision with an obstacle. After crossing the obstacle, the camera assembly moves downward and protrudes from the bottom of the protective shell 5; a protective airbag 12 is installed on the inner wall of the protective shell 5, and a connecting tube 11 is installed in the drone body 1, and an end of the connecting tube 11 close to the protective shell 5 is connected to the protective airbag 12, and an end of the connecting tube 11 away from the protective shell 5 is connected to the top of the air cavity 9. When the camera assembly is in the air cavity 9 When moving upward, the gas in the air cavity 9 will be squeezed and transported into the protective airbag 12 through the connecting tube 11, thereby causing the protective airbag 12 to expand, thereby wrapping the camera component that is moving and contracted in the protective shell 5, providing buffering and protection for the camera component, and preventing the drone body 1 from falling down in severe conditions, that is, when the drone body 1 collides with an external obstacle. At this time, the drone body 1 may fall at an angle, and the two groups of bottom plates 4 and the second legs 3 cannot cooperate with the first legs 2 to form an effective support for the drone body 1, so one group of the bottom plates 4 will tilt and contact the ground first, and then under the impact of the drone body 1, the corresponding second leg 3 will rotate relative to the first leg 2, and then the camera component will move into the protective shell 5 through the transmission assembly. At this time, the protective airbag 12 will expand and wrap the camera component, thereby providing buffering and protection for the camera component.

[0034] See also Figure 1-Figure 3 , Figure 6-Figure 7Preferably, the transmission assembly includes a transmission rod 21; one end of the second pull rope 15 away from the groove 18 is wound on the transmission rod 21, the transmission rod 21 is rotatably arranged in the drone body 1, and the transmission rod 21 is symmetrically arranged along the center of the drone body 1, and the opposite ends of the two groups of transmission rods 21 are respectively rotatably matched with driving gears 24, so that from the relative position, the two groups of driving gears 24 are respectively arranged at the two ends of one group of transmission rods 21, and the side of the driving gear 24 away from the transmission rod 21 is meshed with a driven gear 23, and the driving gear 24 and the driven gear 23 are both rotatably arranged in the drone body 1, and the driving gear 24 and the transmission The rods 21 are driven by chains or belts, and a transmission shaft is fixedly arranged at the center of the driving gear 24, which is connected to the transmission rod 21. In this way, after the transmission rod 21 rotates, the driving gear 24 is driven to rotate through the transmission shaft. Since the diameter of the driving gear 24 is larger than the diameter of the driven gear 23, the rotation of the transmission rod 21 will cause the driven gear 23 to rotate quickly through the driving gear 24. Since the drone body 1 can only move forward or backward in one direction at the same time, only one set of bottom plate 4 obstacles will come into contact at the same time, which will not affect the rotation of the driven gear 23.

[0035] Furthermore, preferably, a winding roller 13 is fixedly arranged between the two groups of driven gears 23, and one end of the first pull rope 14 away from the camera assembly is wound on the winding roller 13. A connecting storage groove 10 is arranged on the top of the air cavity 9, and the two ends of the winding roller 13 rotate through the storage groove 10 and are fixed to the driven gear 23, and the winding roller 13 and the storage groove 10 are sealed and rotatably connected, so that the gas in the air cavity 9 will not leak from the connection between the storage groove 10 and the winding roller 13. The winding roller 13 is rotatably arranged in the storage groove 10. When a group of bottom plates 4 comes into contact with an obstacle and rotates, the driving gear 24 is rotated through the second pull rope 15 and the transmission rod 21. The rotation of the driving gear 24 drives the driven gear 23 to rotate, and the rotation of the driven gear 23 drives the winding roller 13 to rotate. The rotation of the winding roller 13 winds the first pull rope 14, thereby causing the camera assembly to move upward in the air cavity 9.

[0036] See also Figure 1-Figure 10Preferably, the camera assembly includes a second connecting block 8; the first connecting block 6 is installed at the bottom of the second connecting block 8, the camera body 7 is arranged at the bottom of the first connecting block 6, the top of the second connecting block 8 is slidably arranged in the air cavity 9, and the top of the second connecting block 8 is fixedly connected to the first pull rope 14 in the transmission assembly, so that when the transmission rod 21 rotates to reel in the first pull rope 14, the second connecting block 8 will be pulled to move upward, and the second connecting block 8 and the air cavity 9 are sealed and slidably connected, so when the second connecting block 8 moves upward, the gas in the air cavity 9 will enter the protective airbag 12 through the connecting pipe 11, causing it to expand, and the upward movement of the second connecting block 8 will drive the first connecting block 6 and the camera body 7 to shrink. In the protective shell 5, the camera body 7 is protected by the protective shell 5. After the drone body 1 passes over the obstacle, the second leg 3 rotates and resets. At the same time, the second connecting block 8 moves downward and resets under the action of its own gravity, the first connecting block 6 and the camera body 7. The movement and reset of the second connecting block 8 allows the gas in the protective airbag 12 to enter the air cavity 9 through the connecting pipe 11. Of course, a spring can also be provided between the second connecting block 8 and the air cavity 9 to provide a driving force for the movement and reset of the second connecting block 8, and to ensure the stability of the camera body 7 when it protrudes from the protective shell 5. It should be noted that the drone body 1 and the camera assembly are both prior art, and the relevant specific structure and working principle are described in detail here.
