[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] As shown in the drawings, Figures 1 to 6 The present application provides a laser radar mapping device for unmanned aerial vehicle, comprising a mapping body 1, the mapping body 1 is installed at the bottom of the unmanned aerial vehicle body 2, characterized in that: the mapping body 1 is connected with the unmanned aerial vehicle body 2 through the sliding plug assembly 3.

[0027] Specifically, as shown in the drawings, Figures 3 to 6 The sliding plug assembly 3 comprises a sliding plug base 301 arranged at the bottom of the unmanned aerial vehicle body 2, the lower surface of the sliding plug base 301 is provided with a sliding slot 302, one end of the sliding slot 302 extends to the side surface of the sliding plug base 301 and forms a slot entrance 303, the top of the mapping body 1 is connected with a lifting rod 304, the outer periphery of the lifting rod 304 is sleeved with a lifting cylinder 305, the top of the lifting cylinder 305 is provided with a plug-in seat 306, the side surface of the plug-in seat 306 is provided with a docking groove corresponding to the sliding slot 302.

[0028] When it is needed to install the mapping body 1 to the unmanned aerial vehicle body 2, the docking groove on the side surface of the plug-in seat 306 is aligned with the sliding slot 302, the plug-in seat 306 is attached with the slot entrance 303, the plug-in seat 306 is pushed to the sliding slot 302 in the direction of the sliding slot 302, so that the mapping body 1 is installed to the unmanned aerial vehicle body 2.

[0029] Further, in order to improve the installation reliability of the mapping body 1, as shown in the drawings, Figure 3As shown, the bottom of the unmanned aerial vehicle body 2 is provided with an extension hole 307, the extension hole 307 is provided with an extension spring 308, the extension spring 308 is connected with an extension plug rod 309. Correspondingly, the top of the plug-in seat 306 is provided with a docking hole 310, the bottom of the docking hole 310 is provided with an electromagnetic sheet 311, when the plug-in seat 306 is plugged into the inner side of the sliding slot 302, the docking hole 310 is opposite to the extension hole 307.

[0030] It should be noted that under the elastic force of the extension spring 308, the extension plug rod 309 is retracted in the extension hole 307, at the same time, the electromagnetic sheet 311 is electrically connected with the unmanned aerial vehicle body 2, when the unmanned aerial vehicle body 2 is not taking off, the electromagnetic sheet 311 is in a power-off state, therefore, when the surveying and mapping body 1 is installed to the unmanned aerial vehicle body 2, the extension plug rod 309 is always retracted in the extension hole 307.

[0031] After the unmanned aerial vehicle takes off, the electromagnetic sheet 311 is powered and has magnetism, thereby attracting the extension plug rod 309, the lower end of the extension plug rod 309 is inserted into the docking hole 310. In this state, on the one hand, the plug-in seat 306 is limited by the sliding slot 302 and can only move in the sliding slot 302, on the other hand, the plug-in seat 306 is limited by the docking hole 310 and can only move in the vertical direction, the combination of the two limitations makes the plug-in seat 306 unable to move, that is, the surveying and mapping body 1 cannot move, thereby improving the connection reliability of the surveying and mapping body 1.

[0032] Further, as shown, Figure 3 The bottom of the sliding slot 302 is provided with a driving rack 4, the lifting cylinder 305 is provided with a lifting gear 5, when the plug-in seat 306 is plugged into the sliding slot 302, the lifting gear 5 is engaged with the driving rack 4, the lifting gear 5 is provided below with a clockwork mechanism 6, the lifting gear 5 is connected with the clockwork mechanism 6, the lower end of the clockwork mechanism 6 is connected with a driving rod 7, the driving rod 7 is connected with the lifting rod 304.

[0033] It should be noted that the clockwork mechanism 6 in the embodiment adopts the common clockwork structure in the existing technology, which can store energy and slowly release kinetic energy. During the process that the surveying and mapping body 1 is connected with the unmanned aerial vehicle body 2, the plug-in seat 306 slides in the sliding slot 302, the lifting gear 5 moves relative to the driving rack 4, which causes the lifting gear 5 to rotate, the lifting gear 5 starts the clockwork mechanism 6, the clockwork mechanism 6 stores energy, the clockwork mechanism 6 slowly drives the driving rod 7 to move downward, drives the lifting rod 304 to move downward, which makes the lifting rod 304 gradually extend out of the lifting cylinder 305, thereby making the surveying and mapping body 1 gradually move downward.

[0034] After the unmanned aerial vehicle takes off, the position of the surveying and mapping body 1 is lower than the support of the unmanned aerial vehicle, thereby the support does not surround the surveying and mapping body 1, which will not affect the surveying and mapping of the surveying and mapping body 1.

[0035] The above examples are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements are also considered to fall within the protection scope of the present application.
