Description

Technical Field

[0001] This utility model relates to an installation device for an airborne lidar on a drone, belonging to the field of lidar installation technology. Background Technology

[0036] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0037] This utility model provides an installation device for an airborne lidar on a drone, such as... Figures 1-4 As shown, it includes a lidar body 1, a mounting assembly 2, a reset spring 3, a fixing assembly 5, a connecting assembly 6, and a UAV body 605;

[0038] The lidar body 1 is fixedly attached to the lower part of the mounting component 2, and the fixing component 5 is movably connected to one side of the interior of the mounting component 2; the UAV body 605 is fixedly connected to the lower part of the mounting component 605.

[0039] The reset spring 3 is movably installed in the mounting component 2 to drive the fixing component 5 to move, thereby enabling the lidar body 1 to be mounted on the UAV body 605 through the mounting component 2, the fixing component 5 and the connecting component 6.

[0040] The technical concept of this utility model is that the lidar body 1 is mounted on the UAV body 605 through the mounting component 2, the fixing component 5 and the connecting component 6. The whole adopts a split structure, so there is no need to disassemble the whole device when replacing the equipment, and the installation time is short. Secondly, the design of the return spring 3 facilitates disassembly and realizes dynamic buffering. The whole installation device realizes quick disassembly and assembly, high stability and multiple protection functions, which significantly improves the safety of UAV lidar operation and data acquisition accuracy.

[0041] like Figure 2 and Figure 3 As shown, the installation component 2 includes a first connecting frame 201, an installation block 202, a limiting plate 204, a push rod 206, and a slide rod 207;

[0042] The bottom of the first connecting frame 201 is fixed to the top of the laser radar body 1, and the top of the first connecting frame 201 is fixed to the bottom of the mounting block 202.

[0043] The mounting block 202 has a cavity structure 203, and a limiting plate 204 is provided in the cavity structure 203. The limiting plate 204 has a sliding hole 205 so that the push rod 206 passes through the limiting plate 204 through the sliding hole 205 and connects to the sliding rod 207.

[0044] In this embodiment, the mounting block 202 is connected to the lidar body 1 via the first connecting bracket 201, which is applicable to most lidar models. By replacing the first connecting bracket 201 with different specifications, quick adaptation can be achieved, reducing costs compared to traditional customized mounting brackets.

[0045] like Figure 4 As shown, the fixing component 5 includes a first locking block 504 and a slider 502;

[0046] The upper surface of the mounting block 202 is provided with a through hole 501 that mates with the first locking block 504, and the slider 502 is fixedly mounted below the first locking block 504.

[0047] The slider 502 is provided with an inclined groove 503, and the slide rod 207 passes through the groove 503. The left and right movement of the slide rod 207 drives the slider 502 and the first locking block 504 to move up and down, so that the first locking block 504 has a hidden position hidden in the mounting block 202 and an extended position protruding from the mounting block 202.

[0048] The mounting device also includes a button 4, which is movably disposed on the upper surface of the mounting block 202;

[0049] The reset spring 3 is mounted on the mounting block 202. One end of the reset spring 3 is connected to the limiting plate 204, and the other end of the reset spring 3 is connected to the button 4.

[0050] When button 4 is pressed, the reset spring 3 is in the abutting position against the limiting plate 204, and the slide bar 207 is in the position away from the limiting plate 204; the first locking block 504 is in the hidden position hidden in the mounting block 202.

[0051] When button 4 is released, reset spring 3 is in the reset position; slide bar 207 is in the position close to limit plate 204; first locking block 504 is in the extended position extending from mounting block 202.

[0052] Connection component 6 includes a second connection bracket 601 and a mounting plate 604;

[0053] The second connecting frame 601 is fixed to the UAV body 605 via the mounting plate 604;

[0054] The second connecting bracket 601 has a mounting groove 602 that mates with the mounting block 202, and a slot 603 that mates with the first locking block 504.

[0055] In addition, the second connecting frame 601 has a protruding structure 606 under the two side plates, and the bottom of the two sides of the mounting block 202 is also provided with a stepped snap-fit ​​structure 208 that cooperates with the protruding structure 606.

[0056] In addition to the first locking block 504, the stepped locking structures 208 on both sides of the mounting block 202 and the protruding structure 606 of the connecting component 6 form a secondary lock, adopting a double mechanical locking mechanism to effectively prevent detachment.

[0057] like Figure 5 and Figure 6 The installation device shown also includes a protective component 7, which includes a support frame 701, a rotating rod 703, and a protective frame 704.

[0058] The support frame 701 is located on one side of the mounting plate 604; the protective frame 704 is located on the other side of the mounting plate 604 via the rotating rod 703.

[0059] It should be noted that the protective frame 704 in this embodiment adopts a transparent design.

[0060] The protection component 7 also includes a second card block 702 and a third card block 705;

[0061] The second locking block 702 is located at the bottom of the support frame 701, and the third locking block 705 is located at the bottom of the protective frame 704. The second locking block 702 and the third locking block 705 are movably locked together.

[0062] The protective component 7 achieves a 90° rotation of the protective frame 704 via the rotating rod 703. Combined with the quick-locking function of the second locking block 702 and the third locking block 705, the protection can be deployed during the take-off and landing phase to prevent the lidar from being contaminated by dust during operation, reduce the risk of collision damage, resist foreign object impact, and improve the service life and safety of the equipment.

[0063] The specific work process is as follows:

[0064] When using the device, the operator can first open the third locking block 705 from the outside of the second locking block 702. Then, through the rotational connection between the rotating rod 703 and the protective frame 704, the operator can flip the protective frame 704 upward. Then, the operator presses the button 4, which drives the push rod 206 to move backward, so that the push rod 206 can drive the slide rod 207 to move backward.

[0065] Through the sliding connection between the slide rod 207 and the slide groove 503, when the slide rod 207 moves backward, it can drive the slider 502 to move downward through the slide groove 503. This allows the slider 502 to drive the first locking block 504 to move downward, so that the first locking block 504 can move into the mounting block 202. Then, the operator can insert the mounting block 202 into the mounting groove 602. Next, through the elastic force of the return spring 3, the return spring 3 can push the button 4 to perform the reset operation. This allows the button 4 to drive the push rod 206 and the slide rod 207 to perform the reset operation, so that the first locking block 504 can move upward and engage with the locking groove 603. This allows the mounting block 202 to be fixedly connected to the second connecting frame 601, so that the laser radar body 1 can be connected to the drone body 605.

[0066] Then the staff can flip the protective frame 704 downwards to reset it, so that the third locking block 705 can engage with the second locking block 702, so that the protective frame 704 can protect the lidar body 1, and the drone body 605 can drive the lidar body 1 to fly.
