When the contour track chassis encounters a raised obstacle, the first support roller lifts up, causing the sleeve, spring stop plate and round tube to move, thereby compressing the buffer spring to reduce impact and vibration. When encountering a recessed obstacle, the buffer spring extends, thereby pushing the first support roller to move, so that the track body makes full contact with the ground, thus playing the role of buffering and shock absorption and increasing passability.

[0036] 2. By setting multiple suspension mechanisms at the bottom of the crossbeam, when the second support roller encounters an obstacle, the second support roller will move down with the depression of the ground or rise with the convexity. The moving second support roller will push the track body to make full contact with the ground, complete the automatic contouring, so that the contouring track chassis can move smoothly on uneven ground, and avoid the track body from slipping during use.

[0037] By setting a tensioning mechanism at one end of the crossbeam and rotating the solenoid tube, the compression distance of the compression spring can be easily adjusted. The compression spring pushes the connecting seat and guide wheel to move, and the moving guide wheel will squeeze the track body, thereby facilitating the adjustment of the track body's tension. The compression spring also allows the guide wheel to automatically tension the track body at any time, ensuring the track body's performance. Attached Figure Description

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0046] Please refer to Figures 1-6 In the embodiments of the utility model, a profiling track chassis comprises a track body 100, a tensioning mechanism 200, two buffering and damping mechanisms 300 and multiple suspension mechanisms 400. A transmission wheel 110 is in transmission connection with the top of one end inside the track body 100. A crossbeam 120 is arranged inside the track body 100, and multiple carrier assemblies are arranged on the top of the crossbeam 120.

The upper spring stop plate 330 is disposed at the bottom of the connecting block 310. A round rod 331 is fixedly connected to the bottom of the upper spring stop plate 330. The round tube 340 is slidably sleeved with the round rod 331. A lower spring stop plate 341 is sleeved and fixedly fixed to the top of the outer wall of the round tube 340. Furthermore, a sleeve 342 is fixedly connected to the bottom of the round tube 340. A buffer spring 350 is disposed on the outside of the round rod 331. The two ends of the buffer spring 350 are fixedly connected to the upper spring stop plate 330 and the lower spring stop plate 341, respectively. The first support roller 360 is rotatably connected to the sleeve 342. The displacement assembly includes a second screw tube 311 and a second screw rod 320. The second screw tube 311 is rotatably connected to the bottom of the connecting block 310. A rectangular rod 312 is disposed inside the second screw tube 311, and one end of the rectangular rod 312 is fixedly connected to the bottom of the connecting block 310. The bottom of the second screw rod 320... The top of the spring stop plate 330 is fixedly connected to the screw 320. A rectangular hole 321 is provided on the screw 320, and the rectangular hole 321 is slidably sleeved with the rectangular rod 312. The suspension mechanism 400 includes a support frame 410, a telescopic rod 420, two ribs 430 and two spiral springs 440. The top of the support frame 410 is fixedly connected to the crossbeam 120. Rotating grooves 411 are provided at the bottom of both sides of the support frame 410. The telescopic rod 420 is located at the top of the inner side of the support frame 410. The two ribs 430 are rotatably connected to the two ends of the telescopic rod 420 respectively. The bottom of the rib plate 430 is rotatably connected to a support roller 431. A connecting rod 432 is fixedly connected to the bottom of one end of the rib plate 430, and the connecting rod 432 is rotatably connected to the rotating groove 411 at the corresponding position. A fixing rod 433 is fixedly connected to the rib plate 430. Two spiral springs 440 are both located at the bottom of the inner side of the support frame 410.

A fixing block 442 is fixedly connected to one side of the spring cover 441, and the fixing block 442 is sleeved and fixed to the fixing rod 433 at the corresponding position.

[0050] In the embodiment, the screw rod two 320 is limited by rotating the screw pipe two 311 and using the rectangular rod 312 and the rectangular hole 321 in cooperation, so that the screw rod two 320, the spring upper stopper 330 and the round rod 331 move, and the buffer spring 350 is compressed, so that the buffer spring 350 is compressed by a proper distance.

The rotation of the supporting wheel two 431 drives the rib plate 430 to rotate around the connecting rod 432 as the center, so that the telescopic rod 420 is deflected and stretched or contracted. The deflection of the rib plate 430 drives the fixed block 442 and the spring cover 441 to move, so that the volute spiral spring 440 is compressed or stretched. When the rib plate 430 is reset, the volute spiral spring 440 automatically rebounds, so that the suspension mechanism 400 is automatically reset.
