[0002] The small remote reconnaissance vehicle is a portable ground robot, which can be carried by one person, rapidly deployed in a narrow space, loaded with a camera, real-time collection of on-site video data, detection of dangerous objects or reconnaissance of the on-site environment. At present, the technology of the small remote reconnaissance vehicle is constantly improving, including mechanical structure, battery life, communication performance, remote control system and autonomous navigation capability. These improvements make them more flexible and more powerful.

The moving mode of the track needs metal track plates and the driven wheel set to realize meshing transmission, so the noise generated by the track during movement is relatively large, it is difficult to meet the low sound reconnaissance requirement, and the track can adapt to the use of wild fields or relatively flat ground. It is difficult for the track to meet the working conditions of climbing slopes and climbing obstacles in some terrain with too large slope or obvious height difference, which affects the use effect of the small remote reconnaissance vehicle.

[0033] Working principle:

[0034] The small remote reconnaissance vehicle can realize the remote reconnaissance function according to the prior art of the contrast file. The small remote reconnaissance vehicle is controlled and reconnoitered through the buttons of the external remote controller. Specifically, the rocker output switch of the external remote controller is output to the communication module of the handheld control end. The handheld control end encodes and transmits the signal to the data transmission receiving device of the small remote reconnaissance vehicle through the data sending module. The data transmission receiving device decodes the received signal and outputs the signal to the PCB mainboard. The PCB mainboard contains a single-chip microcomputer. The single-chip microcomputer controls the sensing module, the action module and the communication module after receiving the signal. At this time, the rudder, the camera and the positioning assembly of the sensing module work to reconnoiter the environment. The moving assembly of the action module adjusts the angle to realize the ideal vehicle body posture and motion operation. After the camera collects the image, the camera encodes the image and outputs the image to the image transmission transmitting device of the small remote reconnaissance vehicle.

The extension rod 63 is welded outside the wheel disc 62. The three extension rods 63 are fixed at three equilateral angles to form equidistant supports. The rotating shaft 65 at the other end of the extension rod 63 can support the auxiliary wheel 64. When the reconnaissance vehicle chassis 1 is driven by the driven wheel 3 and the main driving wheel 4 rotates to move forward, the auxiliary wheel 66 at the front end of the extension rod 63 touches the high-difference wall surface. The auxiliary wheel 66 at the bottom is pushed forward to form a fulcrum to force the auxiliary wheel 64 driven by the extension rod 63 above to stretch upwards until the auxiliary wheel 64 above contacts the upper end surface of the high-difference terrain to form a new fulcrum to pull the auxiliary wheel 64 below to the upper side. In this way, most obstacles can be overcome, and the reconnaissance vehicle can move normally in an environment with large height differences.

[0037] The protection structure of the small remote reconnaissance vehicle:

[0038] The high-carbon steel material is used to make the vertical rods 53, and multiple vertical rods 53 are arranged in parallel. The multiple vertical rods 53 form a support structure to buckle the outer shell 52 above the bottom plate 51. In this way, the outer shell 52 can protect the internal reconnaissance vehicle control device 2 from being damaged by the outside world. The high-thickness transparent tempered glass is used for the protective glass 54. In this way, the high-strength glass is extremely hard, and it can also protect the inside camera 56 from being damaged in a dangerous environment where explosions, collapses, and falling objects are likely to occur. The inside camera 56 can collect images for environmental reconnaissance. In this way, the effective protective structure can protect the camera from being damaged too quickly during the reconnaissance work. Embodiment 2
