Description

Technical Field

[0001] The present invention relates to the technical field of explosion-proof UAVs; in particular, the present invention relates to an explosion-proof UAV with an automatic leveling function during landing. Background Art

[0002] Unmanned aerial vehicles, or "drones" for short, are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by on-board computers. They are widely used in daily inspection operations in coal mines. The underground environment of coal mines is relatively complex, not only containing a large number of flammable and explosive objects, but also in a small space, resulting in high flight requirements for drones and requirements for safety and explosion-proof performance in all aspects. During the use of drones, they not only need to effectively maintain balance during flight, but also need to maintain effective balance when landing, so as to effectively avoid the impact force when landing.

[0003] At present, in order to improve the safety during landing and reduce the damage to the drone body caused by the impact force of landing, the explosion-proof drones in the prior art generally adopt a buffer-type chassis for effective buffering.

[0004] For example, the patent with application number 202010935483.X provides a protective mechanism for a drone, which achieves a protective effect by performing shock absorption and buffering at the bottom of the drone, thereby enhancing the service life of the drone. The protective mechanism of the drone solves the problem that existing drones are prone to certain collisions with the ground when falling. However, the single buffering performance can only be limited to the stable landing state of the drone. When the drone lands or falls in an inclined state with one side higher and the other side lower, if it cannot automatically level, the propeller on the lower side will hit the ground and cause damage, or the drone will fall to the ground, which is very likely to cause damage to the drone. Summary of the invention

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 4 As shown, a typical embodiment of the present invention provides an explosion-proof UAV with an automatic leveling function during landing, comprising an explosion-proof battery compartment 1, a battery 2 and a support frame 3, characterized in that support rods 4 are provided at both ends of the front and rear sides of the battery 2, and support blocks 5 supported at the bottom of the support rods 4 are provided on the front and rear inner wall surfaces of the explosion-proof battery compartment 1; A support frame 3 is provided on both sides of the bottom of the explosion-proof battery compartment 1. The top of the support frame 3 is rotatably connected to the explosion-proof battery compartment 1. A circular gear 6 is fixedly provided on the top side of the support frame 3. A rack 7 is meshed at the bottom of the circular gear 6. The rack 7 is fixedly connected to the support block 5 on the opposite side thereof. When the bottom end of the support frame 3 swings upward, it can drive the support block 5 to detach from the bottom of the support rod 4 supported by it. A buffer plate 8 is provided at the bottom of the explosion-proof battery compartment 1, and a first buffer spring 9 is provided between the bottom of the buffer plate 8 and the inner bottom wall of the explosion-proof battery compartment 1, and when the support block 5 is detached from the bottom of the support rod 4 supported by it, the buffer plate 8 and the bottom of the battery 2 form a falling space 10 for the battery 2 to fall.

[0024] In the initial state, the support block 5 is stably supported at the bottom of the support rod 4 , so that the battery 2 is in a horizontal state in the explosion-proof battery compartment 1 . At this time, the battery 2 has strong stability.

[0025] During the landing of the drone, when the drone is in a tilted state, the support frame 3 on the lower side will touch the ground first, and then, under the action of gravity, the side support frame 3 will rotate upward with its top end as the center.

[0026] During the rotation of the support frame 3, the circular gear 6 is driven to rotate, and the circular gear 6 drives the rack 7 to move outward. At this time, the rack 7 drives the support block 5 on the opposite side of the rotating support frame 3 to move inward, so that the support block 5 is pulled away from the bottom of the support rod 4.

[0027] At this time, the support rod 4 at the lower end of the battery 2 remains supported by the support block 5 on that side, and under the action of gravity and inertia, the higher end of the battery 2 will rotate downward around the support rod 4 at the lower end and contact the buffer plate 8. The buffer plate 8 cooperates with the first buffer spring 9 to buffer and support the battery 2.

[0028] In the process of the battery 2 colliding with the buffer plate 8, an inertial force will be generated, which will cause the drone to tilt toward the higher side as a whole, so that the drone will automatically compensate for the phenomenon of one side being too low caused by the tilting when the drone is parked, preventing the drone from tipping over when parked or the propeller on the lower side from touching the ground.

[0029] The support frame 3 includes an outer frame 3.1, an inner frame 3.2, a bottom plate 3.3 and a stopper 3.4. The top of the outer frame 3.1 is rotatably mounted on the explosion-proof battery compartment 1. The circular gear 6 is fixed to the side of the top of the outer frame 3.1. The inner frame 3.2 is inserted into the outer frame 3.1, and the bottom end of the inner frame 3.2 is vertically provided with a bottom plate 3.3 for supporting the ground. The stopper 3.4 is fixedly provided on the upper surface of the outer frame 3.1. A lifting and lowering stopper 11 is provided in the explosion-proof battery compartment 1. The stopper 11 is located on the inner side of the stopper 3.4. A second buffer spring 12 is provided on the top of the stopper 11. When the inner frame 3.2 moves upward in the outer frame 3.1, its top side pushes the stopper 11 upward away from the inner side of the stopper 3.4.

[0030] In the initial state, the blocking rod 11 is kept in the lowest position by the pressure of the second buffer spring 12. At this time, the blocking rod 11 is located on the inner side of the block 3.4 and limits the block 3.4 to prevent the support frame 3 from rotating upward, thereby locking the support frame 3.

[0031] When the support frame 3 contacts the ground, the bottom plate 3.3 contacts the ground first, and under the action of gravity or inertia, the bottom plate 3.3 is subjected to force to drive the inner frame 3.2 to move upward inside the outer frame 3.1, and at this time, the inner frame 3.2 pushes the blocking rod 11 to compress the second buffer spring 12. The second buffer spring 12 provides effective buffering for the drone.

[0032] When the tilt angle of the drone is too large, causing the second buffer spring 12 to be compressed to the shortest state, the blocking rod 11 detaches from the inner side of the block 3.4. At this time, under the action of gravity or inertia, the support frame 3 will rotate upward with its top as the center, thereby causing the support block 5 on the higher side to be pulled out from the bottom of the support rod 4, so that the battery 2 can compensate for the tilt of the drone by deflecting the inertia force generated when it hits the buffer plate 8, so that the drone can stop and land on the ground in a more balanced state.

[0033] The top surface of the stopper 3.4 is set to be an arc surface with the rotation center of the outer frame 3.1 as the center of the circle, and a limiting groove 13 is set in the explosion-proof battery compartment 1. When the bottom end of the blocking rod 11 moves to the circumferential surface where the top surface of the stopper 3.4 is located, its top end contacts the inner top wall of the limiting groove 13. The limiting groove 13 is set to limit the highest position of the blocking rod 11, so that during the rotation of the support frame 3, the bottom end of the blocking rod 11 is displaced on the top surface of the stopper 3.4. At this time, the stopper 3.4 can limit the blocking rod 11 and keep the blocking rod 11 in the highest position, which is not only conducive to the subsequent resetting of the blocking rod 11, but also the blocking rod 11 will not affect the rotation of the support frame 3.

[0034] In the initial state, the support frame 3 is tilted outward at the bottom, and a first rotating plate 14 with an outer end tilted upward is provided above the top of the inner frame 3.2. The bottom end of the first rotating plate 14 is rotatably installed in the explosion-proof battery compartment 1. When the inner frame 3.2 moves upward, the first rotating plate 14 drives the blocking rod 11 to move upward.

[0035] By providing the first rotating plate 14, the initial state of the support frame 3 is such that the bottom end thereof is tilted outward, thereby increasing the distance between the bottoms of the two support frames 3 and improving the supporting effect of the support frame 3 on the drone. In addition, the arm of the compensating force generated by the battery 2 on the entire drone when it falls is also increased, thereby improving the self-balancing effect of the drone.

[0036] In a relatively specific embodiment, the blocking rod 11 includes a vertical section 11.1 and a transverse section 11.2, the vertical section 11.1 is used to limit the stopper 3.4, and the first rotating plate 14 pushes the transverse section 11.2 upward when rotating upward. When the top end of the blocking rod 11 contacts the inner top wall of the limiting groove 13, the first rotating plate 14 is in a state where the outer end is tilted upward.

[0037] During the rotation of the support frame 3 , the top end of the first rotating plate 14 will not cross the vertical line, so that the first rotating plate 14 can be reset downward under the action of its own eccentric weight, forming a self-resetting performance of the first rotating plate 14 .

[0038] The bottom end of the first rotating plate 14 is fixedly connected to the second rotating plate 15, and the side of the second rotating plate 15 facing the inner frame 3.2 is an arc-shaped surface with the rotation center of the outer frame 3.1 as the center. The buffer plate 8 is supported on the bottom of the battery 2 in the initial state, and the bottom end of the second rotating plate 15 is located on the upper surface of the buffer plate 8. When the blocking rod 11 is detached from the side of the block 3.4, the second rotating plate 15 presses the buffer plate 8 downward to form a falling space 10.

[0039] In a relatively specific embodiment, the first rotating plate 14 and the second rotating plate 15 are in a state of being biased toward one side of the first rotating plate 14 as a whole, so as to maintain the self-resetting performance of the first rotating plate 14 and the second rotating plate 15 as a whole under the action of their own biased weight.

[0040] At the same time, in the initial state, the buffer plate 8 is supported at the bottom of the battery 2 under the action of the first buffer spring 9, and has a buffering effect on the battery 2. When the buffering stroke of the support frame 3 is covered by the top of the inner frame 3.2, that is, when the second buffer spring 12 is compressed to the shortest state, the second rotating plate 15 has pressed the buffer plate 8 down to separate from the battery 2, so that the drone automatically forms a falling space 10 for the battery 2, providing a guarantee for the realization of the self-balancing performance.

[0041] A longitudinal rod 16 is connected to the rack 7, and the support block 5 is fixedly installed on the top of the longitudinal rod 16. When the battery 2 falls to contact the buffer plate 8, the lateral spacing of the support rod 4 is greater than the distance between the longitudinal rod 16 and the outer end of the support block 5.

[0042] With such arrangement, during the falling process of the battery 2, the support rod 4 first contacts the longitudinal rod 16, pushes the longitudinal rod 16 to move, and then contacts the buffer plate 8. When the longitudinal rod 16 is pushed by the falling process of the battery 2, the longitudinal rod 16 drives the support frame 3 to further rotate through the rack 7 and the circular gear 6. At this time, the angle between the upper surface of the support frame 3 and the lower side of the battery 2 becomes smaller, further increasing the lever arm when the inertial force formed by the falling battery 2 is applied to the drone as a whole, thereby improving the self-balancing effect.

[0043] A positioning plate 17 is disposed on the upper surface of the stopper 3.4 at the inner side of the support rod 4, and the battery 2 is in an initial state, and the outward side of the positioning plate 17 contacts the support rod 4.

[0044] By setting the alignment plate 17, during the resetting process of the battery 2, the operator keeps the two support frames 3 rotated to the maximum angle. At this time, the support block 5 is outside the movement trajectory of the support rod 4, and under the action of the first buffer spring 9, the buffer plate 8 will lift the battery 2 to the highest position that can be lifted. After that, the support frame 3 is released. During the resetting process of the support frame 3, the support block 5 and the alignment plate 17 will move to one side of the support rod 4. The alignment plates 17 on the left and right sides push the support rods 4 on the left and right sides respectively, so that the battery 2 is centered in the left and right directions of the explosion-proof battery compartment 1, and cooperates with the supporting force of the first buffer spring 9 to finally achieve the centering in the height direction. At this time, all components of the drone are restored to the initial state.

[0045] The inner top wall of the explosion-proof battery compartment 1 is provided with a sleeve groove 18. When the top end of the battery 2 is inserted into the sleeve groove 18, the support rod 4 is located above the stopper 3.4 and is spaced apart from the stopper 3.4. When the top end of the battery 2 is separated from the sleeve groove 18, the support rod 4 is supported by the stopper 3.4.

[0046] In the initial state, the sleeve groove 18 can limit the battery 2 in the left and right and front and back directions, thereby improving the stability and safety of the drone during flight and in the initial state.

[0047] When the inner frame 3.2 in the support frame 3 moves upward to push the blocking rod 11 out of the block 3.4 area, the second rotating plate 15 presses the buffer plate 8 downward, so that the first buffer spring 9 is further compressed, thereby forming a falling space 10 for the battery 2, increasing the buffer force, and causing the top end of the battery 2 to disengage from the sleeve groove 18.

[0048] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above implementation without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the scope of the present invention.
