Description

Technical Field

[0001] This utility model relates to the field of drone photography technology, and in particular to a drone mapping airborne platform. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and onboard program control devices. They have no cockpit, but are equipped with autopilots and program control devices. Ground personnel, personnel on ships, or at mother aircraft remote control stations track, locate, remotely control, telemetry, and transmit data to them using radar and other equipment.

[0003] Chinese utility model patent CN220640250U discloses an intelligent UAV mapping and photography airborne platform, including a fixed plate, a fixed frame fixedly connected to the upper surface of the fixed plate, a placement platform inside the fixed frame, a damper fixedly connected to the upper surface of the fixed plate, two limiting springs fixedly connected to the inner sidewall of the fixed frame, two guide grooves opened on the upper surface of the placement platform, two guide blocks slidably connected inside each of the two guide grooves, two positioning clamps fixedly connected to the upper surfaces of the two sets of guide blocks, a horizontal plate fixedly connected to the upper surface of the placement platform, and the sides of the two limiting springs that are close to each other fixedly connected to the sides of the positioning clamps that are far apart from each other. Two locking holes are opened on the right side of each positioning clamp.

[0004] During the installation of the photographing equipment on the aforementioned intelligent drone mapping and photography airborne platform, the photographing equipment must first be inserted between two positioning plates, and then the positioning plates are locked with multiple bolts or other fasteners and multiple locking holes. The operation is relatively cumbersome and does not improve the installation efficiency of the photographing equipment. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an airborne platform for UAV mapping.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an unmanned aerial vehicle (UAV) mapping airborne platform, including a UAV body, a mounting shell is provided below the horizontal section of the UAV body, a connecting mechanism for connecting the mounting shell to the UAV body is provided on the UAV body, a camera is provided inside the mounting shell, a clamping plate is slidably provided inside the mounting shell, the side wall of the clamping plate near the camera abuts against the side wall of the camera, a screw is rotatably installed on the side wall of the clamping plate away from the camera, the screw passes through the mounting shell and is threadedly connected, and a knob is fixed on the screw.

[0007] By adopting the above technical solution, firstly, rotating the knob drives the screw to rotate. Since the screw is rotatably connected to the clamping plate, the clamping plate moves away from the camera, allowing the camera to be removed from the mounting housing, thus completing the camera removal. Similarly, first, the camera is placed inside the mounting housing, then the knob is rotated to rotate the screw in the opposite direction, causing the clamping plate to move closer to the camera until the clamping plate presses the camera firmly against it, thus completing the camera installation. The operation is simple and convenient, improving the efficiency of installing or removing photographic equipment.

[0008] Furthermore, the connecting mechanism includes a connecting component, which includes an annular shell fixed to the bottom of the horizontal section of the UAV body, a rectangular sleeve slidably fitted on the annular shell, a threaded post set on the rectangular sleeve, and a connecting block fixed between the mounting shell and the threaded post. The connecting mechanism also includes a positioning component for fixing the annular shell and the rectangular sleeve.

[0009] By adopting the above technical solution, the fixed state of the annular shell and the rectangular sleeve is released by the positioning component, and the rectangular sleeve is pulled downward, so that the threaded column connected to the rectangular sleeve and the connecting block connected to the threaded column are both away from the annular shell, thus completing the disassembly of the mounting shell.

[0010] Furthermore, the threaded column penetrates the bottom of the rectangular sleeve and is threadedly connected. A cavity is formed inside the annular shell. Sliding through holes communicating with the cavity are formed on both side walls of the annular shell. The positioning assembly includes a positioning plate slidably disposed in the sliding through hole and a clamping block inserted into the inner side of the annular shell. The threaded column is rotatably installed on the bottom of the clamping block. The clamping block abuts against the positioning plate. The positioning plate penetrates the annular shell and is slidably engaged. The positioning assembly also includes a connecting plate fixed to the positioning plate and a return spring fixed between the connecting plate and the inner side wall of the cavity and in an elongated state. A positioning through hole is formed on the side wall of the clamping block and is inserted into the positioning plate. The number of sliding through holes, the number of positioning through holes, and the number of positioning assembly groups are equal and their positions correspond one-to-one.

[0011] By adopting the above technical solution, the rotating connecting block drives the threaded column to rotate. Since the threaded column is threadedly connected to the rectangular sleeve, the clamping blocks connected to the threaded column both descend until the clamping blocks are separated from the positioning plate. The return spring gradually contracts, causing the connecting plate connected to the return spring and the annular shell connected to the return spring to move towards the sliding through hole until the positioning plate separates from the positioning through hole. At this point, the rectangular sleeve and the annular shell can be separated, thus completing the disassembly of the mounting shell.

[0012] Furthermore, the rectangular sleeve and the connecting block are jointly provided with a limiting mechanism. The limiting mechanism includes a connecting sleeve that passes through and is fixed in the rectangular sleeve, a limiting block that is slidably disposed in the connecting sleeve, a support spring that is fixed between the top of the limiting block and the inner top wall of the connecting sleeve, and a stop block that is fixed on the connecting block and abuts against the limiting block.

[0013] By adopting the above technical solution, the limiting block is pressed upwards, the supporting spring is stressed and gradually contracts until the limiting block and the stop block separate. At this time, rotating the stop block and driving the connecting block to rotate half a turn can separate the clamping block and the positioning plate. The limiting block and the stop block reduce the probability of vibration during the movement of the UAV body, which may cause the threaded column to rotate.

[0014] Furthermore, a limiting through hole is provided through the top of the mounting shell, and a slider that is slidably connected to the limiting through hole is fixed to the top of the clamping plate.

[0015] By adopting the above technical solution, the limiting of the through hole and the limiting of the slider improves the stability of the clamping plate during movement.

[0016] Furthermore, a sliding rod that slides in cooperation with the connecting plate is fixed inside the cavity on the annular shell, and the return spring is sleeved on the sliding rod.

[0017] By adopting the above technical solution and the design of the slide bar, the stability of the connecting plate and the return spring during movement is improved.

[0018] Furthermore, the distance between the bottom of the limiting block and the top of the mounting shell gradually increases from the stop block to the connecting sleeve, and the side wall of the stop block away from the limiting block gradually increases from the stop block to the connecting sleeve.

[0019] By adopting the above technical solution, the connecting block rotates in the opposite direction, making it easier for the stop block to pass through the limiting block.

[0020] Furthermore, the sidewalls of the two sets of positioning plates that are close to each other are inclined surfaces, and the distance between the two sets of inclined surfaces gradually increases from top to bottom.

[0021] By adopting the above technical solution, it is easy to insert the clamping block between the two sets of positioning plates.

[0022] In summary, this utility model has the following beneficial effects: In this application, by setting up a clamping plate, a screw and a knob, the efficiency of installing or disassembling the photographic equipment is improved. Attached Figure Description

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figures 1-5As shown in the illustration, this application discloses an airborne platform for UAV mapping, including a UAV body 1, a connecting mechanism 3, and a limiting mechanism 10. A mounting shell 2 is disposed below the horizontal section of the UAV body 1. A camera 4 is disposed within the mounting shell 2, and a clamping plate 5 is slidably disposed within the mounting shell 2. The sidewall of the clamping plate 5 near the camera 4 abuts against the sidewall of the camera 4, and a screw 6 is rotatably mounted on the sidewall of the clamping plate 5 away from the camera 4. The screw 6 passes through the mounting shell 2 and is threadedly connected, and a knob 7 is fixed on the screw 6. By adopting the above technical solution, firstly, rotating the knob 7 drives the screw 6 to rotate. Since the screw 6 is rotatably connected to the clamping plate 5, the clamping plate 5 moves away from the camera 4, and finally, the camera 4 can be removed from the mounting shell 2, thus completing the disassembly of the camera 4. Similarly, first place the camera 4 inside the mounting housing 2, then rotate the knob 7 and drive the screw 6 to rotate in the opposite direction, so that the clamp 5 moves toward the direction of the camera 4 until the clamp 5 presses the camera 4 together, thus completing the installation of the camera 4. The operation is simple and convenient, improving the efficiency of installing or removing the camera.

[0031] The connecting mechanism 3 is mounted on the UAV body 1 and includes a connecting component 31 and a positioning component 32. The positioning component 32 includes an annular shell 311, a rectangular sleeve 312, a threaded post 313, and a connecting block 314. The annular shell 311 is fixed to the bottom of the horizontal section of the UAV body 1. A cavity is formed inside the annular shell 311, and sliding through holes 8 communicating with the cavity are formed on both side walls inside the annular shell 311. The rectangular sleeve 312 is slidably fitted onto the annular shell 311, and the threaded post 313 passes through the bottom of the rectangular sleeve 312 and is threadedly connected. The threaded post 313 is disposed on the rectangular sleeve 312, and the connecting block 314 is fixed between the mounting shell 2 and the threaded post 313. The fixed state of the annular shell 311 and the rectangular sleeve 312 is released by the positioning component 32, and the rectangular sleeve 312 is pulled downward so that the threaded post 313 connected to the rectangular sleeve 312 and the connecting block 314 connected to the threaded post 313 are both away from the annular shell 311, thus completing the disassembly of the mounting shell 2.

[0032] The positioning assembly 32 is used to fix the annular shell 311 and the rectangular sleeve 312. The positioning assembly 32 includes a positioning plate 321, a clamping block 322, a connecting plate 323, a return spring 324, and a slide rod 325. The positioning plate 321 is slidably disposed in the sliding through hole 8, and the positioning plate 321 passes through the annular shell 311 and slides in engagement. The clamping block 322 is inserted into the inner side of the annular shell 311, and a positioning through hole 9 is provided on the side wall of the clamping block 322 to engage with the positioning plate 321. The threaded post 313 is rotatably mounted on the bottom of the clamping block 322, and the clamping block 322 abuts against the positioning plate 321. The connecting plate 323 is fixed on the positioning plate 321, and the return spring 324 is fixed between the connecting plate 323 and the inner side wall of the cavity and is in an elongated state. Rotate the connecting block 314 and drive the threaded column 313 to rotate. Since the threaded column 313 is threadedly connected to the rectangular sleeve 312, the threaded column 313 and the clamping block 322 connected to the threaded column 313 both descend until the clamping block 322 is separated from the positioning plate 321. The return spring 324 gradually contracts, so that the connecting plate 323 connected to the return spring 324 and the annular shell 311 connected to the return spring 324 both move towards the sliding through hole 8 until the positioning plate 321 separates from the positioning through hole 9. At this time, the rectangular sleeve 312 and the annular shell 311 can be separated, thereby completing the disassembly of the mounting shell 2.

[0033] A limiting mechanism 10 is jointly disposed on the rectangular sleeve 312 and the connecting block 314. The limiting mechanism 10 includes a connecting sleeve 101, a limiting block 102, a support spring 103, and a stop block 104. The connecting sleeve 101 is disposed through and fixed in the rectangular sleeve 312, and the limiting block 102 is slidably disposed inside the connecting sleeve 101. The support spring 103 is fixed between the top of the limiting block 102 and the inner top wall of the connecting sleeve 101, and the stop block 104 is fixed on the connecting block 314 and abuts against the limiting block 102. Pressing the limiting block 102 upwards causes the support spring 103 to be stressed and gradually contract until the limiting block 102 separates from the stop block 104. At this point, rotating the stop block 104 and causing the connecting block 314 to rotate half a turn can separate the abutting block 322 from the positioning plate 321. The limiting of the limiting block 102 and the stop block 104 reduces the probability of vibration during the movement of the UAV body 1, which could cause the threaded column 313 to rotate.

[0034] A limiting hole 11 is provided through the top of the mounting shell 2, and a slider 12 that is slidably connected to the limiting hole 11 is fixed to the top of the clamping plate 5. The limiting hole 11 and the slider 12 limit the movement of the clamping plate 5, thereby improving the stability of the clamping plate 5.

[0035] A slide rod 325, which slides and engages with the connecting plate 323, is fixed inside the cavity of the annular shell 311. The return spring 324 is sleeved on the slide rod 325. The slide rod 325 improves the stability of the connecting plate 323 and the return spring 324 during movement.

[0036] The distance between the bottom of the limiting block 102 and the top of the mounting shell 2 gradually increases from the stop block 104 to the connecting sleeve 101, and the side wall of the stop block 104 away from the limiting block 102 gradually increases from the stop block 104 to the connecting sleeve 101. When the connecting block 314 rotates in the opposite direction, it facilitates the stop block 104 to pass through the limiting block 102.

[0037] The sidewalls of the two sets of positioning plates 321 that are close to each other are inclined surfaces, and the distance between the two sets of inclined surfaces gradually increases from top to bottom. This facilitates the insertion of the clamping block 322 between the two sets of positioning plates 321.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
