[0002] In mechanical design, a parallel linear structure typically refers to a mechanical structure in which multiple components move in a straight line along parallel tracks. It has a wide range of applications, such as in lawn mowing.

[0003] Currently, this type of parallel straight-walking structure is usually driven by a motor, with rollers directly contacting the ground. The roller contact area is limited, and the operating mechanism on the upper part of the parallel straight-walking structure is relatively heavy. The parallel straight-walking structure has high requirements for operational stability and adhesion, and the roller contact is difficult to meet the above requirements, especially in environments where the walking conditions are relatively slippery. Utility Model Content

[0004] The purpose of this invention is to provide a tracked parallel straight-running structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tracked parallel straight-moving structure, comprising:

[0007] The inner mounting bracket assembly has two outer walls connected to the outer side plate via outer connecting columns. The drive gear is connected to the upper left side between the inner mounting bracket assembly and the outer side plate via a rotating shaft. The support wheel is installed on the lower left and lower middle sides between the inner mounting bracket assembly and the outer side plate via a rotating shaft. The tension wheel is installed on the lower right side between the inner mounting bracket assembly and the outer side plate via a rotating shaft. The outer side plate is provided with an adjustment mechanism for adjusting the tension wheel.

[0008] The drive gear, support wheel, and tensioning wheel are surrounded by an internal toothed track, and the drive gear meshes with the teeth on the inner wall of the internal toothed track.

[0009] Preferably, the inner mounting bracket assembly includes an inner connecting plate and side uprights disposed at both ends of the inner connecting plate, and the outer connecting column is connected between the side uprights and the outer side plate.

[0010] Preferably, the inner mounting bracket assembly is provided with a drive motor, and the output shaft of the drive motor is connected to a drive gear.

[0011] Preferably, the side plate has a waist-shaped groove, one end of the rotating shaft inside the tensioning wheel is connected to the waist-shaped groove, and the other end is connected to the adjustment mechanism.

[0012] Preferably, the adjusting mechanism includes an outer sleeve fixedly connected to the right side of the outer wall of the outer side plate, an inner rod body slidably connected inside the outer sleeve, the right end of the inner rod body being connected to the other end of the rotating shaft inside the tension wheel, and a fastening bolt screwed onto the outer wall of the outer sleeve, the fastening bolt penetrating the outer sleeve and contacting the outer wall of the inner rod body.

[0013] Preferably, an adjusting screw is screwed to the left end of the outer sleeve, the adjusting screw is installed parallel to the outer sleeve, and the right end of the adjusting screw is supported on the left end of the inner rod.

[0014] Preferably, a reinforcing tube is welded to the lower surface of the inner connecting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This solution is based on the drive motor driving the drive gear to rotate, which in turn drives the internal tooth track to rotate.

[0034] Analysis of the above content: Based on the usage requirements, two drive motors 15 are set on both sides to synchronously drive the drive gears 7 on both sides (the synchronous drive here adopts the existing control principle, such as the two motors receiving the same speed command, such as the speed signal issued by the PLC, and each achieves synchronization through independent closed-loop control (such as speed loop, which will not be elaborated here). Even if there is a deviation in the movement of the internal tooth track 8 on both sides, the operator can adjust it (existing technology, which will not be elaborated here).

[0035] Depending on the usage requirements, the speed of the two drive motors can also be controlled by 15 to achieve operations such as turning and U-turn (existing circuit control technology will not be elaborated here).

[0036] Example 4:

[0037] Please see Figure 1-3 Based on Embodiment 2, this utility model provides a technical solution: a waist-shaped groove 9 is provided on the side plate 3, one end of the rotating shaft in the tensioning wheel 10 is connected to the waist-shaped groove 9, and the other end is connected to the adjustment mechanism.

[0041] Analysis of the above content: When adjustment is required, loosen the fastening bolt 14 so that the inner rod 12 is pulled outward relative to the outer tube 11. The inner rod 12 pushes the tension wheel 10 to move to the right, and at the same time tightens the inner tooth track 8. Then tighten the fastening bolt 14 to fix the inner rod 12 and the outer tube 11.

[0042] Example 6:

[0043] Please see Figure 1-3 Based on Embodiment 5, this utility model provides a technical solution: an adjusting screw 13 is screwed to the left end of the outer sleeve 11, the adjusting screw 13 is installed parallel to the outer sleeve 11, and the right end of the adjusting screw 13 is supported on the left end of the inner rod 12.
