Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle frames, in particular to a surveying and mapping unmanned aerial vehicle frame. Background Art

[0002] With the development of drone technology, drones are usually used to carry out surveying and mapping. Compared with traditional surveying and mapping, drones are more flexible, efficient, precise, low-cost, widely applicable, and have a short production cycle. They have obvious advantages in quickly acquiring high-resolution images in small areas and areas with difficult flight.

[0003] The bottom frame of the current surveying and mapping UAV cannot be adjusted according to the height of the surveying and mapping instrument installed at the bottom. When the size of the surveying and mapping instrument is high, the short size of the bottom frame will cause the surveying and mapping instrument to contact the ground, which will cause damage to the surveying and mapping instrument when the drone lands. In addition, the structural strength of the current frame is not enough. When the side of the drone collides with the external structure, the frame cannot effectively protect the surveying and mapping instrument. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A surveying and mapping UAV frame comprises a UAV body, wherein an adjustable support frame component group is arranged at the bottom of the UAV body, the adjustable support frame component group is used to support the UAV body, the adjustable support frame component group comprises a fixed frame body, a window groove is arranged inside the fixed frame body, a dynamic inner frame rod is arranged inside the fixed frame body, a vertical protective rod is arranged inside the dynamic inner frame rod, a supporting foot plate is arranged at the bottom of the dynamic inner frame rod, and a horizontal protective rod is arranged on the side of the vertical protective rod.

[0007] Preferably, two groups of the adjusting support frame component groups are provided, and the two groups of the adjusting support frame component groups are symmetrically distributed on both sides of the bottom of the drone body, and the top of the fixed frame body is connected to the bottom of the drone body.

[0008] Preferably, a viewing window groove is provided on the fixed frame, a sliding groove is provided on the fixed frame at a position corresponding to the moving inner frame rod, and the fixed frame and the moving inner frame rod are in sliding contact through the sliding groove.

[0009] Preferably, the bottom of the dynamic inner frame rod is connected to a supporting foot plate, and the bottom of the supporting foot plate is used to contact the ground.

[0010] Preferably, the vertical protection bars and the horizontal protection bars are provided in multiple groups, and the multiple groups of vertical protection bars and the horizontal protection bars are staggeredly connected to the inner frame rods of the moving machine.

[0011] Preferably, the fixed frame and the dynamic inner frame rod are both made of plastic, and the vertical protection rod and the horizontal protection rod are made of the same material as the fixed frame.

[0012] Preferably, the fixed frame body and the dynamic inner frame rod are provided with threads at positions corresponding to the transverse protection rod, and the fixed frame body and the dynamic inner frame rod are connected to the transverse protection rod through the threads.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The frame of the surveying and mapping UAV is provided with an adjustable support frame component group. The bottom frame of the current surveying and mapping UAV cannot be adjusted according to the height of the surveying instrument installed at the bottom. When the size of the surveying instrument is high, the short size of the bottom frame will cause the surveying instrument to contact the ground, and the surveying instrument will be damaged when the UAV lands. In the corresponding designed adjustable support frame component group, the structure composed of the fixed frame body and the dynamic inner frame rod can be adjusted. The dynamic inner frame rod can slide up and down in the fixed frame body, and the position of the dynamic inner frame rod in the fixed frame body is locked by connecting the horizontal protection rod. The height of the surveying instrument installed at the bottom of the UAV body is adapted by adjusting the dynamic inner frame rod, ensuring that the bottom of the supporting foot plate is lower than the surveying instrument, thereby ensuring that the surveying instrument will not contact the ground and cause damage when the UAV lands, thereby improving the adaptability and practicality of the UAV frame;

[0015] 2. The frame of a surveying and mapping UAV is provided with an adjustable support frame component group. At present, the structural strength of the frame is not enough. When the side of the UAV collides with the external structure, the frame cannot effectively protect the surveying and mapping instrument. In the corresponding designed adjustable support frame component group, the fixed frame body, the dynamic inner frame rod, the vertical protection rod and the horizontal protection rod form a protection structure. When the UAV collides with an object from the side during flight, it is blocked by the protection structure composed of the fixed frame body, the dynamic inner frame rod, the vertical protection rod and the horizontal protection rod, and cannot hit the surveying and mapping instrument at the bottom of the UAV body. Therefore, the frame of the UAV improves the protection of the surveying and mapping instrument when the UAV is in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] There are two groups of adjustment support frame component groups 02, and the two groups of adjustment support frame component groups 02 are symmetrically distributed on both sides of the bottom of the drone body 01, and the top of the fixed frame body 21 is connected to the bottom of the drone body 01.

[0030] Working principle: The bottom frame of the current surveying and mapping UAV cannot be adjusted according to the height of the surveying instrument installed at the bottom. When the size of the surveying instrument is high, the short size of the bottom frame will cause the surveying instrument to contact the ground, and the surveying instrument will be damaged when the UAV lands. In the corresponding designed adjustment support frame component group 02, the structure composed of the fixed frame body 21 and the dynamic inner frame rod 23 can be adjusted. The dynamic inner frame rod 23 can slide up and down in the fixed frame body 21, and the position of the dynamic inner frame rod 23 in the fixed frame body 21 is locked by connecting the cross protection rod 26. The dynamic inner frame rod 23 is adjusted to adapt to the height of the surveying instrument installed at the bottom of the UAV body 01, ensuring that the bottom of the supporting foot plate 25 is lower than the surveying instrument, thereby ensuring that the surveying instrument will not contact the ground and cause damage when the UAV lands, thereby improving the adaptability and practicality of the UAV frame. At present, the structural strength of the frame is not enough. When the side of the drone collides with the external structure, the frame cannot effectively protect the surveying instrument. In the corresponding designed adjustment support frame component group 02, the fixed frame body 21, the dynamic inner frame rod 23, the vertical protection rod 24 and the horizontal protection rod 26 form a protection structure. When the drone collides with an object from the side during flight, it is blocked by the protection structure composed of the fixed frame body 21, the dynamic inner frame rod 23, the vertical protection rod 24 and the horizontal protection rod 26, and cannot hit the surveying instrument at the bottom of the drone body 01. Therefore, the drone frame improves the protection of the surveying instrument when the drone is in use.
