Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to an anti-impact unmanned aerial vehicle with an instantaneous buffer structure. Background Art

[0002] A drone is a flying object that does not have a pilot on board and is controlled remotely or automatically. Drones can use the force of aerodynamics to cooperate with adaptive or remote control flight. In the early days, drones were mainly used for military purposes, but recently they have also been used in agriculture, wildfire monitoring and firefighting, distribution, logistics, communications, photography, disaster situations and other fields in the civilian sector. At the same time, drones are also used in various sports such as football and basketball. Therefore, the scope of application of drones has a tendency to gradually expand; During the flight, drones are prone to losing control due to improper operation or information transmission problems, and are prone to falling after losing control. Therefore, it is necessary to provide effective buffering protection when the drone falls to avoid causing serious damage to the drone.

[0003] However, existing drones still have certain defects when in use; For example, the UAV device for UAV sports proposed in application number CN201980002548.0 includes a driving unit including one or more propellers to drive flight; a cage formed to surround the driving unit to protect the driving unit; and a kicking unit configured to protrude from the cage and rotatably coupled to one side of the cage, wherein the kicking unit can be fixed in position or rotated on the cage according to the operation of the user. This application has the effect of enjoying the sport of using a ball on the ground like a football by configuring a kicking unit that can kick or push a ball on the ground on the UAV device. However, in actual use, there are still the following problems: The UAV device for sports uses a spherical frame structure installed on the outer ring to effectively protect the UAV device, so that the impact can be buffered when the UAV device falls to achieve a shock-absorbing protection effect. However, the frame structure is easy to divide the airflow generated by the driving part, which will affect the flight effect and reduce the use effect. However, the UAV device for sports use is only protected by the frame structure when it falls, so that the frame structure is deformed when it is impacted, which in turn squeezes and damages the internal UAV device when deformed, reducing the protection effect.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the present case.

[0005] In view of the above problems, an innovative design is carried out based on the original impact-proof UAV with an instantaneous buffer structure. Summary of the invention

[0006] The purpose of the present invention is to provide an impact-resistant UAV with an instantaneous buffer structure to solve the problem in the above-mentioned background technology that the frame structure divides the airflow, affecting the flight effect and reducing the protection effect.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an anti-impact UAV with an instantaneous buffer structure, comprising a UAV main body, The outer ring of the drone body is fixedly mounted with a connection seat at an equal angle, the outer ring of the connection seat is embedded with a servo motor, and the top shaft end of the servo motor is mounted with a propeller blade; The outer ring of the drone body is equipped with a shock absorbing and buffering mechanism; A camera assembly is fixedly installed at the bottom of the drone body, and an arc-shaped guard plate is fixedly installed on the connecting seat at an equal angle, and a movable protection mechanism is slidably connected on the arc-shaped guard plate; A trigger buckle is fixedly installed at an equal angle on the top outer edge of the shock-absorbing and buffering mechanism, and a telescopic protective mechanism is connected between the movable protective mechanism and the arc-shaped protective plate; The outer ring of the telescopic protection mechanism is connected with an airbag triggering mechanism.

[0008] Preferably, the connecting seat, servo motor and propeller blades are installed in four groups on the outer ring of the drone body.

[0009] The above technical solution makes it easier for the servo motor to drive the propeller blades to rotate, thereby generating a lifting airflow, and then using the servo motor and propeller blades set at equal angles to generate a balanced lifting airflow, which is conducive to the stable lifting and lowering flight of the impact-proof UAV and improves the flight effect.

[0010] Preferably, the shock-absorbing and buffering mechanism includes a fixed ring plate fixedly mounted on the connecting seat, telescopic limit grooves are opened inside the upper and lower ends of the fixed ring plate, the telescopic limit grooves are internally slidably connected to the limit baffle, one side of the limit baffle is fixedly connected to a connecting rod, the top end of the connecting rod is fixedly connected to an upper protective plate, the bottom end of the connecting rod is fixedly installed with a lower protective plate, a shock-absorbing spring is sleeved on the connecting rod between the upper and lower protective plates and the top surfaces of the upper and lower ends of the fixed ring plate, transparent glass plates are inlaid with equal angles on the inner side of the lower protective plate, four groups of transparent glass plates are arranged, the outer circles of the upper and lower protective plates are connected with linkage plates at equal angles, and four groups of linkage plates are arranged.

[0011] Preferably, the telescopic limit groove, limit baffle and connecting rod are distributed at equal angles inside the upper and lower ends of the fixed ring plate, the upper protective plate and the lower protective plate both form a telescopic shock-absorbing structure with the fixed ring plate through shock-absorbing springs, and the transparent glass plate corresponds to the camera assembly.

[0012] By adopting the above technical scheme, the upper and lower protective plates with spherical structure design in the shock-absorbing and buffering mechanism can resist the impact suffered by utilizing the characteristics of the spherical structure when the main body of the UAV falls. The extension and retraction of the upper and lower protective plates can further reduce the shock and buffer the impact suffered, thereby improving the anti-shock effect of the anti-shock UAV with an instantaneous buffer structure.

[0013] Preferably, the movable protection mechanism includes a limit slide seat slidably sleeved on the upper and lower ends of the arc-shaped guard plate, an arc-shaped slide plate is fixedly connected between the limit slide seats at the upper and lower ends, a positioning plate is fixedly installed on the top surface of the top limit slide seat, an expansion airbag is fixedly connected to the inner side of the positioning plate, a connecting head is installed on one side of the expansion airbag, and the connecting head is engaged with the positioning plate.

[0014] The above technical solution makes it easy for the movable protection mechanism to shrink and fold when not falling, so as not to affect the lifting airflow generated by the rotation of the propeller blades to enhance the lifting and falling flight effect. At the same time, it is easy to pop out instantly when falling, and provide wrapping protection for the propeller blades, thereby improving the fall protection effect of the impact-proof UAV with an instantaneous buffer structure.

[0016] Preferably, the movable plate is fixedly connected to the arc-shaped slide plate, and the movable plate forms a telescopic structure with the fixed plate through a telescopic spring and a positioning tube.

[0017] The adoption of the above technical solution facilitates the engagement and separation of the telescopic protective mechanism and the trigger buckle, which is beneficial to the contraction and folding of the movable protective mechanism when engaged, thereby improving the storage effect of the movable protective mechanism. At the same time, it is beneficial to drive the movable protective mechanism to pop out instantly when separated, so as to effectively wrap and protect the propeller blades, further improving the anti-impact protection effect of the anti-impact UAV with an instantaneous buffer structure.

[0018] Preferably, the airbag triggering mechanism includes a sealing valve seat fixedly mounted on the outer end of the positioning tube, a connecting tube is fixedly connected between the sealing valve seats at the front ends of the positioning tube at the upper and lower ends, a hose is connected to the top end of the upper sealing valve seat, the top end of the hose is fixedly connected to the connecting head, a trigger rod is slidably connected to the inside of the sealing valve seat, a sealing plug is fixedly mounted on one end of the trigger rod located inside the sealing valve seat, a reset spring is sleeved on the trigger rod between the sealing plug and the inner wall of the sealing valve seat, and a rubber pad is fixedly mounted on the other end of the trigger rod.

[0019] Preferably, the trigger rod forms a movable sealing structure with the front end of the positioning tube through a sealing plug, and the sealing plug is telescopically connected to the sealing valve seat through a reset spring.

[0020] The adoption of the above technical scheme makes it easier for the telescopic protection mechanism to trigger the airbag triggering mechanism when it is instantly popped out, thereby facilitating the instantaneous expansion and deployment of the airbag triggering mechanism when it is compressed, and is beneficial for the inflatable airbag to shield the top of the propeller blade when it is inflated and deployed, thereby facilitating buffering the impact of foreign objects on the propeller blades when falling, thereby improving the impact protection effect of the impact-proof UAV with an instantaneous buffer structure and reducing the damage caused to the impact-proof UAV when it falls.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the impact-proof UAV with an instantaneous buffer structure can stably lift and lower the impact-proof UAV by generating a balanced lifting airflow when driven by servo motors and propeller blades arranged at equal angles; When the main body of the drone falls, the shock absorbing and buffering mechanism will be squeezed, so that the shock absorbing and buffering mechanism and the trigger buckle will be displaced, thereby releasing the restriction on the telescopic protection mechanism, so that the telescopic protection mechanism can be elastically extended, and drive the movable protection mechanism to slide and pop out on the arc-shaped guard plate, which is conducive to wrapping the propeller blades after popping out, thereby improving the protection effect; The telescopic protection mechanism will compress the airbag triggering mechanism when it pops out, causing the airbag triggering mechanism to expand and unfold on the movable protection mechanism, so as to shield and protect the top of the propeller blades after unfolding, which is beneficial to cushion the impact of foreign objects on the propeller blades when falling, further improving the protection effect of the impact-proof UAV with an instantaneous buffer structure and reducing the degree of damage to the propeller blades when falling.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0025] See also Figure 1-8The present invention provides a technical solution: an anti-impact UAV with an instantaneous buffer structure, comprising a UAV body 1, a connecting seat 2 is fixedly installed at an equal angle on the outer ring of the UAV body 1, a servo motor 3 is embedded and installed on the outer ring of the connecting seat 2, a propeller blade 4 is installed on the top shaft end of the servo motor 3, and four groups of the connecting seat 2, the servo motor 3 and the propeller blade 4 are installed on the outer ring of the UAV body 1; The design of the above structure enables the connecting seat 2 to stably connect the servo motor 3 and the drone body 1, so that the servo motor 3 can drive the propeller blades 4 to generate a lifting airflow, and the internal lifting airflow at an equal angle can perform stable lifting and lowering flight operations on the drone body 1, thereby improving stability.

[0026] The outer ring of the drone body 1 is equipped with a shock-absorbing and buffering mechanism 5, which includes a fixed ring plate 501 fixedly sleeved on the connecting seat 2, and telescopic limit grooves 502 are opened inside the upper and lower ends of the fixed ring plate 501, and the internal sliding connection of the telescopic limit groove 502 is connected to a limit baffle 503, and one side of the limit baffle 503 is fixedly connected to a connecting rod 504, and the telescopic limit groove 502, the limit baffle 503 and the connecting rod 504 are distributed at equal angles inside the upper and lower ends of the fixed ring plate 501, and the top of the connecting rod 504 is fixedly connected to an upper protective plate 506, and the bottom of the connecting rod 504 is fixedly installed with A shock absorbing spring 505 is sleeved on the connecting rod 504 between the lower protective plate 507, the upper protective plate 506, the lower protective plate 507 and the top surfaces of the upper and lower ends of the fixed ring plate 501. The upper protective plate 506 and the lower protective plate 507 form a telescopic shock absorbing structure with the fixed ring plate 501 through the shock absorbing spring 505. The inner side of the lower protective plate 507 is inlaid with transparent glass plates 508 at equal angles. Four groups of transparent glass plates 508 are provided. The transparent glass plates 508 correspond to the camera assembly 6. The outer circles of the upper protective plate 506 and the lower protective plate 507 are connected with linkage plates 509 at equal angles. Four groups of linkage plates 509 are provided. The design of the above structure ensures that when the drone body 1 falls and collides with the ground, the impact force will act on the upper protective plate 506 and the lower protective plate 507. At this time, the spherical structures of the upper protective plate 506 and the lower protective plate 507 can effectively resist and buffer the impact. When the upper protective plate 506 and the lower protective plate 507 are hit, they will drive the connecting rod 504 and the limit baffle 503 to slide in a limited manner inside the fixed ring plate 501 through the telescopic limit groove 502, and squeeze the shock-absorbing spring 505. At this time, the shock-absorbing spring 505 generates a reverse thrust, which can effectively buffer the impact suffered by the upper protective plate 506 and the lower protective plate 507, thereby improving the buffering and protection effect of the impact-proof drone with an instantaneous buffer structure, and improving the protection effect of the drone body 1.

[0027] A camera assembly 6 is fixedly installed at the bottom of the drone body 1, an arc-shaped guard plate 8 is fixedly installed on the equi-angle connecting seat 2, and a movable protection mechanism 9 is slidably connected to the arc-shaped guard plate 8. The movable protection mechanism 9 includes a limit slide 901 slidably sleeved on the upper and lower ends of the arc-shaped guard plate 8, and an arc-shaped slide plate 902 is fixedly connected between the upper and lower limit slides 901. A positioning plate 903 is fixedly installed on the top surface of the top limit slide 901, and an inflatable airbag 904 is fixedly connected to the inner side of the positioning plate 903. A connector 905 is installed on one side of the inflatable airbag 904, and the connector 905 is engaged with the positioning plate 903. The design of the above structure ensures that when the drone body 1 is hit, the arc-shaped slide plate 902 will pop out on the outside of the arc-shaped guard plate 8 through the limiting slide seat 901, so that the arc-shaped slide plate 902 cooperates with the arc-shaped guard plate 8 to wrap the propeller blades 4 after popping out, avoiding the impact caused by the fall from directly acting on the propeller blades 4, thereby improving the protection effect of the propeller blades 4, and the inflatable airbag 904 and the positioning plate 903 will also move synchronously with the deployment of the arc-shaped slide plate 902.

[0028] A trigger buckle 7 is fixedly installed at an equal angle on the top outer edge of the shock-absorbing and buffering mechanism 5, and a telescopic protective mechanism 10 is connected between the movable protective mechanism 9 and the arc-shaped guard plate 8. The telescopic protective mechanism 10 includes a fixed plate 1001 symmetrically installed on the surface of the arc-shaped guard plate 8, and a positioning tube 1002 is symmetrically fixed and penetrated on one side of the fixed plate 1001. A movable plate 1003 is slidably sleeved on the positioning tube 1002. The movable plate 1003 is fixedly connected to the arc-shaped slide plate 902, and the outer ring sleeve of the positioning tube 1002 between the movable plate 1003 and the fixed plate 1001 is provided with Telescopic spring 1004, the movable plate 1003 forms a telescopic structure with the fixed plate 1001 through the telescopic spring 1004 and the positioning tube 1002, the inner end of the positioning tube 1002 is fixedly connected with a connecting elbow 1005, one end of the connecting elbow 1005 is connected with a pressure storage tank 1006, the pressure storage tank 1006 is fixedly connected with the fixed plate 1001, and a trigger plate 1007 is fixedly installed on the top of the movable plate 1003, and a positioning buckle 1008 is fixedly connected to the inner end of the trigger plate 1007, and the positioning buckle 1008 is engaged and connected with the trigger buckle 7; The design of the above structure enables that when the upper protective plate 506 drives the trigger buckle 7 to move and releases the locking connection between it and the positioning buckle 1008, the telescopic spring 1004 will cooperate with the blocking of the fixed plate 1001 to push the movable plate 1003 to slide and pop out on the positioning tube 1002, and can drive the movable protective mechanism 9 to pop out to form a wrap-around protection for the propeller blade 4.

[0029] The outer ring of the telescopic protection mechanism 10 is connected to the airbag trigger mechanism 11, which includes a sealing valve seat 1101 fixedly installed on the outer end of the positioning tube 1002, a connecting pipe 1102 is fixedly connected between the sealing valve seats 1101 at the front ends of the positioning tubes 1002 at the upper and lower ends, a hose 1103 is connected to the top of the upper sealing valve seat 1101, and the top of the hose 1103 is fixedly connected to the connector 905, and a trigger rod 1104 is slidably connected to the inside of the sealing valve seat 1101, which is located at the sealing valve seat 1101. A sealing plug 1105 is fixedly installed at one end of the trigger rod 1104 inside the sealing valve seat 1101. The trigger rod 1104 forms a movable sealing structure with the front end of the positioning tube 1002 through the sealing plug 1105. A return spring 1106 is sleeved on the trigger rod 1104 between the sealing plug 1105 and the inner wall of the sealing valve seat 1101. The sealing plug 1105 is telescopically connected to the sealing valve seat 1101 through the return spring 1106. A rubber pad 1107 is fixedly installed at the other end of the trigger rod 1104. The design of the above structure makes it possible for the movable plate 1003 to squeeze and compress the rubber pad 1107 when it pops out, and then the rubber pad 1107 will drive the trigger rod 1104 to slide inside the sealing valve seat 1101. At this time, the compressive force is greater than the elastic force of the return spring 1106, thereby driving the sealing plug 1105 and the positioning tube 1002 to be sealed and separated. At this time, the compressed gas inside the pressure storage tank 1006 will enter the sealing valve seat 1101 through the connecting elbow 1005 and the positioning tube 1002, and transport the compressed gas to the inside of the expansion airbag 904 through the connecting pipe 1102 and the top hose 1103. At this time, the expansion airbag 904 will expand and expand to cover and protect the top of the propeller blade 4. When it is not triggered and the trigger buckle 7 is engaged and connected with the trigger plate 1007, the return spring 1106 will push the sealing plug 1105 and the positioning tube 1002 to form a sealing structure to prevent the compressed gas inside the pressure storage tank 1006 from leaking, thereby improving the sealing stability.
