The movement of the crawler track is buffered by the setting of the buffer spring 2033, so that the crawler track can travel on complex road conditions and maintain stability.

[0039] Working principle:

[0040] When the present invention is in use, when the housing 1 needs to move forward or backward, the first driving motor drives the first driving bevel gear 305 to rotate, thereby driving the first driven bevel gear 304 meshing with it to rotate. The first driven bevel gear 304 drives the fourth driving bevel gear 312 on the two first driving rods 302 on both sides to rotate, and then cooperates with the plurality of transmission bevel gears 310 to drive the third driving bevel gear 311 to rotate. The third driving bevel gear 311 drives the two driving wheels 301 to rotate through the transmission shaft 313. The two driving wheels 301 rotate in the same direction, so that the two crawler bodies 5 have the same movement direction, controlling the housing 1 to move forward or backward;

[0041] When the housing 1 needs to turn, the second driving motor drives the second driving bevel gear 307 to rotate, driving the two second driven bevel gears 306 to rotate simultaneously and in opposite directions. The two first gears 308 are driven to rotate through the two second driving rods 303, thereby driving the two second gears 309 to rotate in the driving box 3. When the second gear 309 rotates, the plurality of transmission bevel gears 310 will make a circular motion in the second gear 309, thereby driving the two third driving bevel gears 311 to rotate in opposite directions. The first driving motor is not energized, so that the first driving bevel gear 305 and the first driven bevel gear 304 remain different, so that the two fourth driving bevel gears 312 remain stationary, and the third driving bevel gear 311 drives the two driving wheels 301 to rotate in opposite directions through the transmission shaft 313, so that the movement directions of the two crawler bodies 5 are different, which is convenient for controlling the housing 1 to perform steering operations;

[0042] The adjusting cylinder 2014 pushes the adjusting rack 2013 to move in the support base 2, thereby driving the adjusting gear 2012 meshed with it to rotate, and the adjusting gear 2012 drives the rotating rod to rotate, and the rotating rod drives the first connecting plate 2011 to rotate, so that the inducer 201 moves in a circular motion around the rotating rod, which is convenient for squeezing the crawler body 5 and adjusting the tightness of the crawler body 5 to meet different working conditions;

[0043] When the crawler track encounters an obstacle while moving on the ground, the auxiliary wheel 203 is squeezed, so that the auxiliary wheel 203 drives the third connecting plate 2031 to rotate around the middle, driving one end of the third connecting plate 2031 to slide in the buffer groove 2032, and then squeezing the buffer spring 2033. The movement of the crawler track is buffered by the setting of the buffer spring 2033, thereby maintaining the stability of the crawler track.

[0044] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
