[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] like Figure 1 As shown, the AGV shock-absorbing drive wheel of this utility model includes a drive wheel 1, a lower cover plate 2, a connecting component 3, a shock-absorbing mechanism 4, an upper cover plate 5, and a limiting component 6. The lower cover plate 2 is fixedly connected to the drive wheel 1 through the connecting component 3. The shock-absorbing mechanism 4 is disposed inside the lower cover plate 2. The upper cover plate 5 is slidably disposed on the lower cover plate 2. The limiting component 6 is fixed on the upper cover plate 5 and abuts against the shock-absorbing mechanism 4.

[0024] The shock absorption mechanism 4 includes a cover plate 41, a spring sleeve 42, and a spring 43. The spring sleeve 42 is arranged around the cover plate 41, and the spring 43 is arranged inside the spring sleeve 42.

[0025] Furthermore, in the aforementioned AGV shock-absorbing drive wheel, the connecting assembly 3 includes a spring washer 31 and a connecting screw 32. The bottom of the lower cover plate 2 is provided with a connecting hole 21. The connecting screw 32 passes through the spring washer 31 and the connecting hole 21 in sequence and engages with the drive wheel 1 through the thread, thereby connecting the lower cover plate 2 and the drive wheel 1 as one unit.

[0026] Furthermore, in the aforementioned AGV shock-absorbing drive wheel, the height of the spring sleeve 42 matches the depth of the lower cover plate 2, the length of the spring 43 is greater than or equal to the height of the spring sleeve 42, the spring 43 is sleeved with the spring sleeve 42, and one end of the spring 43 abuts against the lower cover plate 2. The rigidity and diameter of the spring 43 can be adjusted according to the working conditions. The shock absorption effect is achieved by the expansion and contraction of the spring 43 within the spring sleeve 42.

[0027] Furthermore, in the aforementioned AGV shock-absorbing drive wheel, a set of limiting threaded holes 51 is arranged around the upper cover plate 5. The set of limiting threaded holes 51 consists of three threaded holes 511 arranged in a triangular shape, and the set of limiting threaded holes 51 corresponds to the spring sleeve 42 respectively.

[0028] Furthermore, in the above-mentioned AGV shock-absorbing drive wheel, the limiting component 6 includes three limiting bolts 61, which are threadedly engaged with the threaded hole 511, and the end of the limiting bolt 61 abuts against the other end of the spring 43.

[0029] Preferably, the length of the limiting bolt 61 is adjustable, and the adhesion of the drive wheel 1 can be adjusted by selecting limiting bolts 61 of different lengths to adjust the compression of the spring 43.

[0030] Furthermore, in the above-mentioned AGV shock-absorbing drive wheel, the diameter of the cover plate 41 is smaller than the inner diameter of the lower cover plate 2, the outer diameter of the lower end of the upper cover plate 5 is equal to the diameter of the cover plate 41, the outer diameter of the upper end of the upper cover plate 5 is greater than or equal to the outer diameter of the lower cover plate 2, the cover plate 41 is sleeved inside the lower cover plate 2, and the lower end of the upper cover plate 5 is slidably connected to the lower cover plate 2, so that when the drive wheel 1 is subjected to force, the spring 43 is compressed, and the upper cover plate 5 can synchronously contract into the lower cover plate 2 with the compression amount of the spring 43.

[0031] Specifically, during the shock absorption process of the drive wheel 1, the lower cover plate 2 is subjected to an upward force that is transmitted to one end of the spring 43, while the other end of the spring 43 is limited by the limiting bolt 61. At this time, the spring 43 retracts into the spring sleeve 42 to achieve the shock absorption function. During the retraction of the spring 43, the upper cover plate 5 can synchronously retract into the lower cover plate 2 by the compression amount of the spring 43. When the adhesion of the drive wheel 1 needs to be adjusted, the spring 43 can be compressed by replacing the limiting bolt 61 to change the adhesion of the drive wheel 1.

[0032] In summary, compared with the prior art, the AGV shock-absorbing drive wheel of this utility model has the following advantages and beneficial effects:

[0033] The overall structure is simple. By setting the shock absorption mechanism inside the lower and upper cover plates, the space occupied is effectively reduced, making it easy to use and maintain, and the manufacturing cost is low.
