Description

Technical Field

[0001] The present application relates to the technical field of drone carriers, and specifically to an aerial survey drone carrier for geographic information data collection. Background Art

[0002] Drone aerial survey is a method of using drones for aerial photogrammetry. Drones equipped with cameras or other sensors can collect high-precision and high-resolution images of the ground. Drone aerial survey can be widely used in major national engineering construction, disaster emergency response and treatment, land supervision, and especially in basic surveying and mapping.

[0003] The drone carrier is an extended leg part installed under the drone chassis for parking and supporting the drone. The existing drone carrier increases the contact area between the carrier and the ground when the drone is parked by adding an extension rod to the lower end of the carrier, thereby distributing the pressure. Since the drone carrier part mostly bears the force through structural support, the existing carrier structure only contacts the ground at one end when the drone is parked crookedly, which makes it easy for stress to concentrate and cause damage. In this regard, a drone carrier for aerial surveying used for geographic information data collection is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In response to the deficiencies in the prior art, the present application provides an aerial survey drone carrier for geographic information data collection, which has the advantages of being able to deform the carrier itself to reduce damage when subjected to conditions exceeding the carrier's load range.

[0006] A buffer component for buffering is fixedly installed on the outside of the connecting shaft, and the buffer component includes a rotating wheel fixed on the outside of the connecting shaft and a buffer clamp arranged on the outside of the rotating wheel. The lower end of the UAV chassis is also provided with a limiting component for squeezing the two clamping blocks close together, and the limiting component includes a mounting block fixed on the bottom of the UAV chassis and a limiting rod located in the mounting block.

[0007] Furthermore, the ground contact rod and the support leg are vertically connected, and the support leg is connected below the UAV chassis at an angle to the vertical direction.

[0008] Furthermore, a connecting pipe passes through the shaft core of the rotating wheel, and the connecting pipe is fixed at the middle section of the connecting shaft.

[0009] Furthermore, a groove is recessed on the surface of the rotating wheel, the buffer clamp is hidden in the groove, and the buffer clamp includes a rotating pin fixed on the inner wall of the groove and a clamping block rotatably connected to the outside of the rotating pin.

[0010] Furthermore, the clamping block is L-shaped and extends toward the outer side of the rotating wheel, and there are two clamping blocks in total, and the two clamping blocks are symmetrically arranged.

[0011] Furthermore, a buffer block for bearing the extrusion effect is installed between the two clamping blocks, and a clamping groove is provided on one end of the clamping block away from the rotating pin, and the two ends of the buffer block are respectively clamped with the two clamping grooves.

[0012] Furthermore, a first spring for pushing the two clamping blocks to return to their original position is installed between the two clamping blocks.

[0013] Furthermore, a sliding groove is provided on one side surface of the mounting block facing the rotating wheel, and the limiting rod comprises a sliding plate sliding in the sliding groove and an extension rod fixed on the sliding plate.

[0014] Furthermore, the outer sleeve of the extension rod is provided with a flexible sleeve.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] See also Figure 1-3 In this embodiment, an aerial survey UAV carrier for geographic information data collection includes a UAV chassis 1, a support leg 4 located below the UAV chassis 1, and a ground contact rod 5 located at the lower end of the support leg 4. A shaft sleeve 2 is installed below the UAV chassis 1, and a connecting shaft 3 is rotatably installed inside the shaft sleeve 2. The support leg 4 is fixedly connected to the connecting shaft 3, and the support leg 4 can be movably connected through the connection of the connecting shaft 3.

[0023] Preferably, the ground contact rod 5 and the support leg 4 are vertically connected, and the support leg 4 is connected below the UAV chassis 1 at an angle to the vertical direction.

[0024] Such a design allows the support leg 4 to be subjected to an oblique force when the ground contact rod 5 contacts the ground, thereby enabling the support leg 4 to rotate relative to the UAV chassis 1 to convert the force.

[0025] In this embodiment, a buffering member for buffering is fixedly installed on the outside of the connecting shaft 3 , and the buffering member includes a rotating wheel 6 fixed on the outside of the connecting shaft 3 and a buffering clip arranged on the outside of the rotating wheel 6 .

[0026] It should be noted that a connecting pipe 7 passes through the axis core of the rotating wheel 6 , and the connecting pipe 7 is fixed to the middle section of the connecting shaft 3 , and can pull the rotating wheel 6 to rotate relative to the connecting shaft 3 when the connecting shaft 3 rotates.

[0027] The surface of the rotating wheel 6 in this embodiment is sunken with a groove 8, and the buffer clamp is hidden in the groove 8. The buffer clamp includes a rotating pin 9 fixed on the inner wall of the groove 8 and a clamping block 10 rotatably connected to the outside of the rotating pin 9.

[0028] Preferably, the clamping block 10 is L-shaped and extends toward the outside of the rotating wheel 6 , and there are two clamping blocks 10 , which are symmetrically arranged.

[0029] In this embodiment, a buffer block 13 for bearing the extrusion effect is installed between the two clamping blocks 10. A slot 12 is provided on one end of the clamping block 10 away from the rotating pin 9. Both ends of the buffer block 13 are respectively engaged with the two slots 12.

[0030] Such a design enables the transmission of the impact to be mitigated by squeezing the buffer blocks 13 when the two buffer blocks 13 are clamped close to each other.

[0031] It should be noted that a first spring 11 for pushing the two clamping blocks 10 to return to their original positions is installed between the two clamping blocks 10 , and both ends of the first spring 11 are fixedly connected to the two clamping blocks 10 , respectively.

[0032] In a specific implementation, when the two clamping blocks 10 are not acted upon by external force, the first spring 11 can push the two clamping blocks 10 away from each other.

[0033] The lower end of the drone chassis 1 in this embodiment is also provided with a limiting member for squeezing the two clamping blocks 10 together, and the limiting member includes a mounting block 14 fixed to the bottom of the drone chassis 1 and a limiting rod 15 located in the mounting block 14, and there are two limiting rods 15, and the spacing between the two limiting rods 15 corresponds to the width of the rotating wheel 6, so that when the rotating wheel 6 rotates, it can pull the buffer clamp located in the rotating wheel 6 to cross the two limiting rods 15.

[0034] By setting a limit rod 15 to squeeze the outer edge parts of the two clamping blocks 10, the two clamping blocks 10 are pushed toward the groove 8. At this time, it is necessary to provide an inclined surface on one end surface of the clamping block 10 extending to the outside of the groove 8, so that the inclined surface on the clamping block 10 can move toward the groove 8 when it contacts the limit rod 15.

[0035] In this embodiment, a sliding groove 16 is formed on one side of the mounting block 14 facing the rotating wheel 6 , and the limiting rod 15 includes a sliding plate 151 sliding in the sliding groove 16 and an extending rod 152 fixed on the sliding plate 151 .

[0036] By setting the extension rod 152 of the limiting rod 15 to be connected through the slide plate 151, it is convenient to lift the extension rod 152 to reset the rotating wheel 6. Therefore, a second spring 17 is connected between the slide plate 151 and the inner wall of the slide groove 16 to push the limiting slide plate 151.

[0037] It should be noted that the outer sleeve of the extension rod 152 is provided with a flexible sleeve 153, and the flexible sleeve 153 contacts the clamping block 10, which can improve the service life and further achieve effective buffering.

[0038] A buffer pad 18 is fixedly installed below the drone chassis 1 to contact the ground and reduce impact.

[0039] The working principle of the above embodiment is:

[0040] When the aerial survey drone for collecting ground information data is parked, the ground contact rod 5 under the drone chassis 1 contacts the ground and bears stress. At this time, if the stress on the ground contact rod 5 exceeds the bearing range, that is, the support leg 4 connected to the drone chassis 1 is tilted, the connecting shaft 3 will rotate relative to the shaft sleeve 2. At this time, the rotating wheel 6 fixedly connected to the outside of the connecting shaft 3 will rotate relative to the limiting rod 15 on one side. Since the two clamping blocks 10 installed on the rotating wheel 6 extend to the outside of the rotating wheel 6, the clamping blocks 10 rotate and contact the two relatively fixed extension rods 152 , then the two clamping blocks 10 are subjected to a force rotating toward the inside of the rotating wheel 6, and the two clamping blocks 10 are brought close to each other to squeeze the buffer block 13 to reduce the force. After the buffer block 13 is deformed under pressure, the relative distance between the two clamping blocks 10 is reduced, so that the clamping blocks 10 rotate over the extension rod 152, and the support leg 4 can rotate relative to the UAV chassis 1. At this time, the UAV chassis 1 falls, so that the buffer pad 18 under the UAV chassis 1 contacts the ground to bear the remaining force, and the cabinet support leg 4 is damaged by stress concentration.
