Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to an emergency rescue unmanned aerial vehicle. Background Art

[0002] As an emerging industry, drones have played an important role in emergency rescue due to their flexibility, intelligence and safety. Especially in urban forest fire fighting and natural disaster rescue, drones can quickly and accurately deal with dangerous situations and ensure the safety of personnel. They can obtain global information at the first time, transport emergency rescue items, assist in the rapid establishment of emergency networks, and provide valuable intelligence support for rescue teams.

[0003] When a drone is landing while carrying emergency rescue items, the drone's own gravity will increase when combined with the transported emergency rescue items. In the existing drones, most of the shock absorption is achieved by setting up an elastic support frame to cushion the impact force generated by the drone during landing. When the drone's own gravity is combined with the transported emergency rescue items, the bending amplitude of the elastic support frame will increase, which will cause the bending amplitude of the support frame to increase. Over time, the support frame will become seriously deformed, affecting the effect of cushioning the landing of the drone. At the same time, due to the poor cushioning effect, the vibration force will be transmitted to the inside of the drone, causing damage to internal components, thereby reducing the service life of the equipment.

[0004] Therefore, the present application provides an emergency rescue drone to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an emergency rescue drone to solve the problem that the existing support frame will bend more and more, which will cause serious deformation of the support frame in the long run, affecting the effect of cushioning the landing of the drone. At the same time, due to the poor cushioning effect, the vibration force is transmitted to the inside of the drone, causing damage to internal components, thereby reducing the service life of the equipment.

[0011] Optionally, the support mechanism further comprises a plurality of positioning holes, which are all provided on the outer wall of each adjustable support leg, the positioning bracket is plugged into the positioning holes, and the outer wall of the adjustable support leg is fixedly connected with an extension plate.

[0012] Optionally, a buffer slide hole is opened at one end of the outer wall of the adjustable supporting leg located at the bottom of the extension plate, a slide bar connecting rod is slidably connected inside the buffer slide hole, a sliding rod is fixedly connected to the top of the slide bar connecting rod, and the sliding rod slides through the extension plate.

[0013] Optionally, a buffer spring is fixedly connected between the top of the sliding rod and the extension plate, matching strip holes are penetrated on opposite sides of the sliding strip connecting rod, connecting rings are fixedly connected to the outer walls of the two groups of sliding strip connecting rods, and a connecting hole is penetrated on one side of the matching strip hole close to the connecting ring.

[0014] Optionally, the buffer mechanism also includes a buffer wheel frame, which is rotatably connected to the end of the adjustable support leg away from the main body, a roller is provided at the end of the buffer wheel frame away from the adjustable support leg, an extension connecting arm is fixedly connected to the top end of the buffer wheel frame away from the adjustable support leg, and a limiting frame is fixedly connected to the top end of the buffer wheel frame away from the extension connecting arm.

[0015] Optionally, a transverse sliding rod is rotatably connected to one end of the extended connecting arm away from the buffer wheel assembly frame, the transverse sliding rod is slidably connected to the inside of the matching strip hole, the transverse sliding rod slides through the connecting hole, the top of the transverse sliding rod is fixedly connected to the contact support plate at one end away from the extended connecting arm, the connection between the contact support plate and the transverse sliding rod is elastic, the bottom of the transverse sliding rod is fixedly connected to an outwardly expanded smooth plate at one end close to the contact support plate, the outer wall of the outwardly expanded smooth plate is a smooth inclined surface, and four buffer mechanisms are provided, and the four buffer mechanisms are respectively provided corresponding to the two groups of adjustable support legs.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, when the mounted item rack on the device lands with the emergency rescue items, the rollers on the buffer wheel assembly frame will first contact the ground. When the protective wing stops running, the buffer wheel assembly frame will rotate on the adjustable support leg with the gravity of the device itself, and the rollers on the buffer wheel assembly frame will roll on the ground until the bottom of the adjustable support leg touches the ground, thereby supporting and placing the drone through multiple adjustable support legs. Through the sliding connection between the transverse slide bar and the matching strip hole, and the rotational connection between the extended connecting arm and the transverse slide bar, the buffer wheel assembly frame will push the slide bar connecting rod to slide upward inside the buffer slide hole during the rotation of the adjustable support leg, so that the slide bar passes through the extension plate and slides upward, stretching the buffer spring, and buffering the drone during landing through the elastic force of multiple buffer springs, reducing the risk of bending and deformation of the adjustable support leg due to excessive impact force caused by the superposition of gravity of the device and the emergency rescue items during the landing of the drone, and avoiding the vibration force being transmitted to the inside of the main body to cause damage to the internal components of the main body, thereby improving the service life of the equipment.

[0017] After the drone rises into the air, the crane assembly is controlled to operate to make the installation rack fall. After the emergency rescue items are fixed inside the installation rack, the crane assembly will control the reeling of the lifting rope to make the installation rack rise. When the slope slide is close to the main body, the slope slide will contact the connection between the transverse slide bar and the contact support plate or the outward expansion smooth plate. As the crane assembly continues to drive the installation rack to rise, the slope slide will slide at the connection between the contact support plate or the outer wall of the outward expansion smooth plate. As the shape of the slope slide is a slope, the transverse slide bar will be pushed to slide in the connecting hole toward the inside of the matching strip hole. At the same time, an upward lifting force will be applied to the connecting ring to facilitate the movement of the transverse slide bar toward one end of the slide bar until the connection between the contact support plate and the transverse slide bar and the outer wall of the installation rack are against each other, so that the installation rack can enter the connecting circle. When the height of the item rack is greater than the connection between the contact support plate and the transverse slide bar, the transverse slide bar loses its outward resistance and is reset by the elastic force of the buffer spring, so that the contact support plate contacts the edge of the bottom outer wall of the item rack, thereby supporting the item rack. In this way, the item rack can be raised to a position close to the main body during the flight of the drone, so that the item rack is placed on two sets of contact support plates. This can not only prevent the emergency rescue items on the item rack from swinging and rotating significantly in the air during the movement of the drone, but also reduce the load-bearing force of the crane assembly and the lifting rope, thereby increasing the service life of the crane assembly and preventing the rescue items from falling off with the crane assembly due to the crane assembly losing control or being unstable in connection with the main body.

[0018] When the slope slide rises to the top, the crane assembly will control the lifting rope to loosen a certain distance, so that the installation item rack is pressed on multiple contact support plates, and at the same time, the contact support plates are slightly deformed, reducing the slope of the contact support plates, further improving the support effect of the contact support plates on the installation item rack carrying rescue items, and improving the stability of the installation item rack placed on the contact support plates, to avoid the contact support plates due to excessive slope and the excessive weight of the installation item rack pushing the transverse slide bar to shrink into the matching strip hole, thereby affecting the support for the installation item rack.

[0019] When the items to be transported are too small, the connecting pendant can be separated from the output end of the crane assembly, and a shorter installation rack can be replaced. After replacing the shorter installation rack, the two control handles can be manually controlled to push inward at the same time, so that the L-shaped sliding rod penetrates the single-arm handle and slides toward the inside of the single-arm handle, and the double-strip hole control plate slides following the L-shaped sliding rod. Through the sliding connection between the positioning bracket and the double-strip hole control plate, the positioning bracket can be driven to slide on the slide rail rod and compress the reset spring, so that the positioning block on the positioning bracket leaves the inside of the positioning hole, and then pressed downward, so that the main body slides downward on the positioning hole through the adjustment hole, thereby reducing the distance between the main body and the connecting ring, and then releasing the control handle to reset the positioning bracket through the elastic force of the reset spring and connect it with the corresponding positioning hole, thereby reducing the height of the drone subjected to wind resistance, thereby further reducing the influence of wind on the flight of the drone during flight, reducing the influence of wind on the drone during flight due to the lighter items carried by the installation rack and the excessive size of the drone, and reducing the amplitude of the drone shaking.

The buffer mechanism 5 is used to disperse the impact force received by the adjustable supporting legs 401 when the main body 1 falls to the ground. The buffer mechanism 5 also includes a buffer wheel frame 501, which is rotatably connected to the end of the adjustable supporting leg 401 away from the main body 1, and the end of the buffer wheel frame 501 away from the adjustable supporting leg 401 is provided with a roller, and the top of the buffer wheel frame 501 is fixedly connected to an extended connecting arm 502 at one end away from the adjustable supporting leg 401, and the top of the buffer wheel frame 501 is fixedly connected to a limited position frame 506 at one end away from the extended connecting arm 502, and the end of the extended connecting arm 502 away from the buffer wheel frame 501 is rotatably connected to a transverse sliding rod 503, and the transverse sliding rod 503 is slidably connected to the inside of the matching strip hole 408, and the transverse sliding rod 503 slides through the connecting hole 409. The end of the part away from the extended connecting arm 502 is fixedly connected to a contact support plate 504, and the connection between the contact support plate 504 and the transverse sliding bar 503 is elastic. The bottom of the transverse sliding bar 503 is fixedly connected to an end of the contact support plate 504, and the outer wall of the outwardly expanded smooth plate 505 is a smooth inclined surface. Four buffer mechanisms 5 are provided, and the four buffer mechanisms 5 are respectively arranged corresponding to the two groups of adjustable support legs 401. Through the sliding connection between the transverse sliding bar 503 and the inside of the matching strip hole 408, and the rotation connection between the extended connecting arm 502 and the transverse sliding bar 503, the buffer wheel group frame 501 will push the sliding bar connecting rod 407 to slide upward in the buffer sliding hole 404 during the rotation process on the adjustable support leg 401, so that the sliding rod 405 passes through the extension plate 403 and slides upward, stretching the buffer spring 406, and the elastic force of multiple buffer springs 406 is used to buffer the landing of the drone; The working principle of the technical solution provided by the present invention is as follows: When the mounted article rack 304 on the device lands with emergency rescue articles, the rollers on the buffer wheel assembly frame 501 will first contact the ground. When the protective wing 103 stops running, the buffer wheel assembly frame 501 will rotate on the adjustable support leg 401 due to the gravity of the device itself, and the rollers on the buffer wheel assembly frame 501 will roll on the ground until the bottom of the adjustable support leg 401 touches the ground, thereby supporting and placing the drone through multiple adjustable support legs 401. Through the sliding connection between the transverse slide bar 503 and the matching strip hole 408, and the rotational connection between the extended connecting arm 502 and the transverse slide bar 503, the buffer wheel assembly frame 501 will push the slide bar connecting rod 407 to slide upward inside the buffer slide hole 404 during its rotation on the adjustable support leg 401, so that the sliding rod 405 passes through the extension plate 403 and slides upward, stretching the buffer spring 406. The elastic force of multiple buffer springs 406 is used to buffer the landing of the drone. When the slope slide 303 is close to the main body 1, the slope slide 303 will contact the connection between the transverse slide bar 503 and the contact support plate 504 or the outwardly expanded smooth plate 505. As the crane assembly 301 continues to drive the installation rack 304 to rise, the slope slide 303 will slide at the connection between the contact support plate 504 or the outer wall of the outwardly expanded smooth plate 505. As the slope slide 303 is in the shape of a slope, the transverse slide bar 503 will be pushed to slide in the connecting hole 409 toward the inside of the matching strip hole 408. At the same time, an upward lifting force will be applied to the connecting ring 410, so that the transverse slide bar 503 can move toward one end of the sliding rod 405 until the connection between the contact support plate 504 and the transverse slide bar 503 and the outer wall of the installation rack 304 are against each other, so that the installation rack 304 can enter the position above the connecting ring 410.

[0039] Embodiment 2, as Figures 1 to 4 and Figure 7As shown, a handle control mechanism 2 is provided on the top of the main body 1, and the handle control mechanism 2 includes a single-arm handle 201, the single-arm handle 201 is fixedly connected to the top of the main body 1, and the outer wall of the single-arm handle 201 is fixedly connected to four V-shaped rods 202, and each V-shaped rod 202 is fixedly connected to a slide rail rod 203 on the side away from the single-arm handle 201, and a positioning bracket 205 is slidably connected to the outer wall of the slide rail rod 203, and a return spring 204 is fixedly connected between the positioning bracket 205 and the V-shaped rod 202, and L-shaped sliding rods 206 are slidably connected on the opposite sides of the single-arm handle 201, and a double-strip hole control plate 207 is fixedly connected to the top of the double-strip hole control plate 207, and a control handle 208 is fixedly connected to the top of the double-strip hole control plate 207, and two adjacent positioning brackets 205 are slidably connected to the double-strip hole control plate 207, so as to separate the connecting pendant 302 from the output end of the crane assembly 301 , replace the shorter installation rack 304. After replacing the shorter installation rack 304, manually control the two control handles 208 to push inward at the same time, so that the L-shaped sliding rod 206 penetrates the single-arm handle 201 and slides toward the inside of the single-arm handle 201, and the double-hole control plate 207 slides along the L-shaped sliding rod 206. Through the sliding connection between the positioning bracket 205 and the double-hole control plate 207, the positioning bracket 205 can be driven to slide on the slide rail rod 203 and compress the reset spring 204, so that the positioning block on the positioning bracket 205 leaves the inside of the positioning hole 402, and then presses downward, so that the main body 1 slides downward on the positioning hole 402 through the adjustment hole 102, thereby reducing the distance between the main body 1 and the connecting ring 410, and then release the control handle 208 to reset the positioning bracket 205 through the elastic force of the reset spring 204 and connect it with the corresponding positioning hole 402; like Figures 1 to 3 , Figure 5 and Figure 6 As shown, the main body 1 also includes a lifting and moving mechanism 3 at the bottom, the lifting and moving mechanism 3 includes a crane assembly 301, the crane assembly 301 is fixedly connected to the bottom of the main body 1, the output end of the crane assembly 301 is threadedly connected to a connecting pendant 302, the outer wall of the connecting pendant 302 is fixedly connected to two groups of slope slides 303, the bottom of the two groups of slope slides 303 is fixedly connected to an installation rack 304, the crane assembly 301 is controlled to operate to make the installation rack 304 fall, and after the emergency rescue items are fixed inside the installation rack 304, the crane assembly 301 will control the winding of the lifting rope to make the installation rack 304 rise.

[0040] The working principle of the technical solution provided by the present invention is as follows: After the drone is lifted into the air, the crane assembly 301 is controlled to operate to make the installation rack 304 fall down. After the emergency rescue items are fixed inside the installation rack 304, the crane assembly 301 will control the rope to reel in, so that the installation rack 304 rises. When the slope slide 303 is close to the main body 1, the slope slide 303 will contact the connection between the horizontal slide bar 503 and the contact support plate 504 or the outward expansion smooth plate 505. As the crane assembly 301 continues to drive the installation rack 304 to rise The slope slide 303 will slide at the connection point of the contact support plate 504 or the outer wall of the outwardly expanded smooth plate 505. As the slope slide 303 is in the shape of a slope, it will push the transverse slide bar 503 to slide in the connecting hole 409 toward the inside of the matching strip hole 408. At the same time, it will apply an upward lifting force to the connecting ring 410 to facilitate the transverse slide bar 503 to move toward one end of the slide bar 405 until the connection point between the contact support plate 504 and the transverse slide bar 503 and the outer wall of the installation rack 304 are against each other, which is convenient for installation. The article rack 304 enters the position above the connecting ring 410. When the height of the article rack 304 is greater than the connection between the contact support plate 504 and the horizontal slide bar 503, the horizontal slide bar 503 loses its outward resistance and is reset by the elastic force of the buffer spring 406, so that the contact support plate 504 contacts the edge of the bottom outer wall of the article rack 304, thereby supporting the article rack 304. In this way, the article rack 304 can be raised to a position close to the main body 1 during the flight of the drone, so that the article rack 304 can be placed on the two sets of contact support plates 504, which can not only prevent the emergency rescue items on the article rack 304 from swinging and rotating significantly in the air during the movement of the drone, but also reduce the load-bearing force of the crane assembly 301 and the lifting rope, thereby increasing the service life of the crane assembly 301 and avoiding the phenomenon that the crane assembly 301 loses control or the connection with the main body 1 is unstable, causing the rescue items to fall off with the crane assembly 301.

[0041] When the ramp slide 303 rises to the top, the crane assembly 301 will control the lifting rope to loosen a certain distance, so that the installation rack 304 is pressed on the multiple contact support plates 504, and at the same time, the contact support plates 504 are slightly deformed, thereby reducing the slope of the contact support plates 504, further improving the support effect of the contact support plates 504 on the installation rack 304 carrying rescue items, and improving the stability of the installation rack 304 placed on the contact support plates 504, thereby preventing the contact support plates 504 from pushing the transverse slide bar 503 to shrink inside the matching strip hole 408 due to the excessive slope and the excessive weight of the installation rack 304, thereby affecting the support for the installation rack 304; When the drone lands with the emergency rescue items, the drone's own gravity and the downward pressure generated by the slope slide 303 on the contact support plate 504 are superimposed, so that the drone can make the contact support plate 504 leave the bottom of the installation rack 304 while cushioning the landing, so that the installation rack 304 can slide to the ground, so that the installation rack 304 and the emergency rescue items inside can be automatically dropped to the ground after the drone lands, and then the drone can be directly controlled to return to the air. In this process, the connection between the horizontal slide bar 503 and the contact support plate 504 will slide on the outer wall of the installation rack 304, waiting for the rescue personnel to take down the rescue items and then return; When the items to be transported are too small, the connecting pendant 302 can be separated from the output end of the crane assembly 301, and a shorter mounting rack 304 can be replaced. After the shorter mounting rack 304 is replaced, the two control handles 208 can be manually controlled to push inward at the same time, so that the L-shaped sliding rod 206 penetrates the single-arm handle 201 and slides inside the single-arm handle 201, and the double-hole control plate 207 slides along with the L-shaped sliding rod 206. The positioning rack 205 can be driven to slide on the slide rail through the sliding connection between the positioning rack 205 and the double-hole control plate 207. 203 slides on and compresses the reset spring 204, so that the positioning block on the positioning bracket 205 leaves the inside of the positioning hole 402, and then presses downward to make the main body 1 slide downward on the positioning hole 402 through the adjustment hole 102, thereby reducing the distance between the main body 1 and the connecting ring 410, and then releases the control handle 208 to reset the positioning bracket 205 and connect it to the corresponding positioning hole 402 through the elastic force of the reset spring 204, thereby reducing the height of the UAV affected by wind resistance, thereby further reducing the impact of wind on the flight of the UAV during flight.
