Description
Technical Field
[0001] This utility model relates to the field of vehicle-mounted drone technology, specifically a vehicle-mounted drone limiting structure. Background Technology

[0003] This utility model includes a base plate, with fixed plates fixedly connected to the upper sides of both the left and right ends of the base plate. Mounting holes are provided on the upper side of the base plate. A placement mechanism is provided between the two fixed plates, and a fixing mechanism is also provided on the upper side of the fixed plate. A motor is fixedly connected to the front side of the right fixed plate. In this utility model, by incorporating a connecting rod, spring, placement plate, and pressure sensor, the impact of external vibrations on the left and right sides of the drone is reduced, preventing external vibrations from shortening the drone's lifespan. By incorporating a slider, moving plate, and buffer plate, the drone is fixed to the placement plate. The limiting plate facilitates the limiting of the drone's upper side, increasing the fixing effect. Under the action of the bidirectional screw, drones of different sizes can be easily fixed, increasing the applicability of the device.
[0004] However, the patent also has the following problems: the device uses two opposing moving limit plates to fix and limit the drone, but because the limit plates are large, they are prone to colliding with the drone's wings when moving in opposite directions, resulting in a small range of applicability and poor practicality of the device. Utility Model Content
[0005] The purpose of this utility model is to provide a vehicle-mounted drone limiting structure, which has the advantages of being able to change the fixed position of the drone and avoid collision between the limiting component and the drone's wing arms, thereby meeting the fixing needs of drones of various sizes.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a vehicle-mounted unmanned aerial vehicle (UAV) limiting structure, including a mounting plate, a protective shell fixed to the top of the mounting plate, and a limiting mechanism and a protective mechanism provided inside the protective shell;
[0007] The limiting mechanism includes a mounting shell, which is fixed to the surface of a mounting plate. A bidirectional lead screw is rotatably connected to the surface of the mounting shell. A first motor is fixed to the surface of the mounting shell. A sliding groove is formed on the surface of the mounting shell. Two movable shells are threadedly connected to the surface of the bidirectional lead screw. An extension plate is slidably connected to the inner wall of the movable shell. A limiting plate is fixed to the top of the extension plate. A bidirectional cylinder is fixed to the top of the mounting shell. An extension block is fixed to the surface of the bidirectional cylinder. A storage shell is hinged to the surface of the extension block. Linkage plates are hinged to both ends of the bidirectional cylinder. The linkage plates are hinged to the storage shell. An L-shaped plate is slidably connected to the inner wall of the storage shell. A damping spring is fixed to the surface of the L-shaped plate. A clamping plate is fixed to the surface of the damping spring.
[0008] As a preferred embodiment of the vehicle-mounted drone limiting structure of this utility model, the protective mechanism includes a rotating shaft, which is rotatably connected to the inner wall of the protective shell. Two transmission gears are fixed on the surface of the rotating shaft, and a rack plate meshes with the surface of the transmission gears. A protective cover is fixed on the top of the rack plate, and the surface of the protective cover is slidably connected to the top of the protective shell.
[0009] As a preferred embodiment of the vehicle-mounted drone limiting structure of this utility model, a U-shaped plate is fixed to the inner wall of the protective shell, a second motor is fixed to the surface of the U-shaped plate, the output shaft of the second motor passes through the U-shaped plate and is fixed with a worm gear, a worm wheel is meshed on the surface of the worm gear, and the worm wheel is fixed to the surface of the rotating shaft.
[0010] As a preferred embodiment of the vehicle-mounted drone limiting structure of this utility model, a guide plate is fixed to the top of the protective shell, and the protective cover is slidably connected to the surface of the guide plate.
[0011] As a preferred embodiment of the vehicle-mounted drone limiting structure of this utility model, both the movable shell and the extension plate have adjustment holes on their surfaces, and the extension plate has multiple adjustment holes.
[0012] As a preferred embodiment of the vehicle-mounted drone limiting structure of this utility model, a screw is rotatably connected to the inner wall of the storage shell, a nut is threaded onto the surface of the screw, a connecting plate is fixed to the surface of the nut, and the top of the connecting plate is fixedly connected to the bottom of the L-shaped plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This invention, through the setting of a limiting mechanism, prevents the wing arms of the drone from colliding when it is fixed. It also allows the device to adapt to the limiting requirements of drones of various sizes. When the drone is at the top of the mounting shell, the first motor is activated to rotate the bidirectional lead screw, causing the two movable shells on both sides to move towards each other due to the threaded connection. This allows the extension plate to contact the surface of the drone's bottom support, thereby clamping and fixing the drone's bottom support. Simultaneously, the limiting plate limits the movement of the drone's bottom support, preventing upward movement. The limiting plate can also move within the movable shell, allowing adjustment of its height to accommodate drones of various thicknesses. The bracket is then retracted by the bidirectional cylinder, causing the two linkage plates on both sides to be pulled towards each other by the piston rod of the bidirectional cylinder. At this time, the linkage plate will drive the storage shell to rotate on the surface of the extension block, so that the two L-shaped plates on both sides can rotate towards each other, allowing the clamping plate to contact the top of the drone's surface, thereby achieving a clamping effect on the top of the drone's surface. At the same time, the damping spring can provide shock absorption and cushioning for the drone, while the rubber pad can prevent damage to the drone's surface, making the drone less susceptible to vibration and damage during vehicle travel. Meanwhile, the L-shaped plate can also move inside the storage shell, thus adapting to the fixing position requirements of drones of various sizes, making this device more practical.

[0024] Please see Figures 1-7 A vehicle-mounted drone limiting structure includes a mounting plate 1, a protective shell 4 fixed to the top of the mounting plate 1, and a limiting mechanism 2 and a protective mechanism 3 provided inside the protective shell 4.
[0025] Mounting plate 1 is used to fix it to the top of the vehicle. Limiting mechanism 2 prevents the wing arms from colliding when the drone is fixed and also enables the device to adapt to the limiting needs of drones of various sizes. Protective mechanism 3 is used to protect the drone. Protective shell 4 is used to prevent airflow from moving the drone while the vehicle is in motion.
[0026] The limiting mechanism 2 includes a mounting shell 201, which is fixed to the surface of the mounting plate 1. A bidirectional lead screw 202 is rotatably connected to the surface of the mounting shell 201. A first motor 203 is fixed to the surface of the mounting shell 201. The output shaft of the first motor 203 passes through the mounting shell 201 and is fixedly connected to the bidirectional lead screw 202. A sliding groove 204 is formed on the surface of the mounting shell 201. Two movable shells 205 are threadedly connected to the surface of the bidirectional lead screw 202. The movable shells 205 are slidably connected to the surface of the sliding groove 204. An extension plate 206 is slidably connected to the inner wall of the movable shell 205. A limit plate 208 is fixed to the top of the extension plate 206, a bidirectional cylinder 209 is fixed to the top of the mounting shell 201, an extension block 210 is fixed to the surface of the bidirectional cylinder 209, a storage shell 212 is hinged to the surface of the extension block 210, a linkage plate 211 is hinged to both ends of the bidirectional cylinder 209, the linkage plate 211 is hinged to the storage shell 212, an L-shaped plate 213 is slidably connected to the inner wall of the storage shell 212, a damping spring 214 is fixed to the surface of the L-shaped plate 213, a clamping plate 215 is fixed to the surface of the damping spring 214, and a rubber pad is fixed to the surface of the clamping plate 215.
[0027] When the drone is positioned on top of the mounting shell 201, the first motor 203 is activated to rotate the bidirectional lead screw 202, causing the two movable shells 205 to move towards each other due to the threaded connection. This allows the extension plate 206 to contact the surface of the drone's bottom support, thus clamping and fixing the drone's bottom support. Simultaneously, the limiting plate 208 limits the movement of the drone's bottom support, preventing the drone from moving upwards. The limiting plate 208 can also move within the movable shell 205, allowing its height to be adjusted to accommodate drone supports of various thicknesses. Afterwards, the bidirectional cylinder 209 retracts, causing the two linkage plates 211 to be... When the piston rods 09 are pulled in opposite directions, the linkage plate 211 will drive the storage shell 212 to rotate on the surface of the extension block 210, so that the L-shaped plates 213 on both sides can rotate in opposite directions, allowing the clamping plate 215 to contact the top of the drone surface, thereby achieving a clamping effect on the top of the drone surface. At the same time, the damping spring 214 can provide shock absorption for the drone, while the rubber pad can prevent damage to the drone surface, making the drone less susceptible to vibration and damage during vehicle travel. Meanwhile, the L-shaped plate 213 can also move inside the storage shell 212, thus adapting to the fixing position requirements of drones of various sizes, making this device more practical.
[0028] Furthermore, the protective mechanism 3 includes a rotating shaft 301, which is rotatably connected to the inner wall of the protective shell 4. Two transmission gears 302 are fixed on the surface of the rotating shaft 301, and a rack plate 303 meshes with the surface of the transmission gears 302. A protective cover 304 is fixed on the top of the rack plate 303, and the surface of the protective cover 304 is slidably connected to the top of the protective shell 4.
[0029] The protective cover 304 can protect the top of the protective shell 4 to prevent airflow, impurities or falling objects from contacting the drone. When the shaft 301 rotates, the transmission gear 302 will drive the protective cover 304 to move through the rack plate 303, so that the top of the protective shell 4 can be in an open state, allowing the drone to fly out normally from inside the protective shell 4.
[0030] Furthermore, a U-shaped plate 305 is fixed to the inner wall of the protective shell 4, a second motor 306 is fixed to the surface of the U-shaped plate 305, the output shaft of the second motor 306 passes through the U-shaped plate 305 and is fixed to a worm 307, a worm wheel 308 is meshed on the surface of the worm 307, and the worm wheel 308 is fixed to the surface of the rotating shaft 301.
[0031] When the second motor 306 starts, it drives the worm 307 to rotate, which in turn drives the worm wheel 308 to rotate, thus enabling the shaft 301 to rotate. Since the worm wheel 308 cannot drive the worm 307, the shaft 301 can achieve a self-locking effect after rotation, preventing the protective cover 304 from moving automatically during vehicle operation.
[0032] Furthermore, a guide plate 309 is fixed to the top of the protective shell 4, and the protective cover 304 is slidably connected to the surface of the guide plate 309;
[0033] The protective cover 304 can slide on the surface of the guide plate 309, thereby providing a guiding effect for the protective cover 304 and preventing positional deviation when the protective cover 304 moves.
[0034] Furthermore, both the movable shell 205 and the extension plate 206 have adjustment holes 207 on their surfaces, and the extension plate 206 has multiple adjustment holes 207 on its surface.
[0035] After the extension plate 206 is adjusted to its position inside the movable shell 205, the extension plate 206 can be limited within the inner wall of the movable shell 205 by passing a bolt through the adjustment hole 207 and then installing a nut.
[0036] Furthermore, a screw 216 is rotatably connected to the inner wall of the storage shell 212, a nut 217 is threadedly connected to the surface of the screw 216, a connecting plate 218 is fixed to the surface of the nut 217, the connecting plate 218 is slidably connected to the inner wall of the storage shell 212, and the top of the connecting plate 218 is fixedly connected to the bottom of the L-shaped plate 213.
[0037] When the screw 216 rotates, the nut 217 can move on the surface of the screw 216, thereby ensuring that the L-shaped plate 213 can move.
[0038] Furthermore, an operating rod 219 is rotatably connected to the surface of the storage shell 212. Both the operating rod 219 and the screw 216 have bevel gears 220 fixed on their lower surfaces, and the two bevel gears 220 mesh with each other.
[0039] Rotating the operating lever 219 causes the bevel gear 220 on its surface to drive the screw 216 to rotate through the bevel gear 220 on the surface of the screw 216, thus enabling the screw 216 to rotate normally.
[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
