[0005] The protective cover can protect the walking wheel assembly, so that the walking wheel assembly is effectively prevented from colliding with other objects when the walking wheel assembly drives the carrier to retreat, and the walking wheel assembly is effectively prevented from being damaged by collision. In addition, the convex ribs are vertically arranged on the outer side of the middle part of the protective cover, so that the deformation of the protective cover is further reliably avoided when the protective cover is impacted, and the protective cover reliably protects the walking wheel assembly. Furthermore, the convex ribs are formed by stamping the protective cover, so that the convex ribs are conveniently formed, and the protective cover has good integrity.

[0006] In a possible implementation, the inner side of the protective cover forms a groove opposite the convex rib, and the groove is formed by stamping the protective cover; by using this structure, after the protective cover is stamped to form the convex rib, the inner side of the protective cover can naturally form the groove, thereby further improving the structural strength and deformation resistance of the protective cover, i.e., the deformation of the protective cover can be further reliably avoided when the protective cover is impacted, i.e., the protective cover can reliably protect the walking wheel assembly.

[0007] In a possible implementation, the upper end of the protective cover is gradually inwardly contracted from bottom to top to form a first skirt, and the two ends of the first skirt extend to the left and right sides of the walking wheel assembly, respectively; by setting the first skirt that is gradually inwardly contracted from bottom to top at the upper end of the protective cover, and since the two ends of the first skirt extend to the left and right sides of the walking wheel assembly, respectively, the structural strength and deformation resistance of the protective cover can be further improved, i.e., the deformation of the protective cover can be further reliably avoided when the protective cover is impacted, i.e., the protective cover can reliably protect the walking wheel assembly.

[0008] In a possible implementation, the upper end of the first skirt is horizontally bent inward to form a fixing edge, and the fixing edge is supported and fixed on the walking wheel assembly; by using this structure, the first skirt and the protective cover can be reliably supported and fixed on the walking wheel assembly by the fixing edge.

[0009] In a possible implementation, the fixing edge is provided with a plurality of fixing holes that are spaced apart in the circumferential direction of the fixing edge, and the protective cover is fixed on the walking wheel assembly by bolts arranged in the fixing holes; by using this structure, the fixing edge can be reliably fixed on the walking wheel assembly by the plurality of bolts, i.e., the protective cover can be reliably fixed on the walking wheel assembly.

[0010] In a possible implementation, the upper end of the protective cover is gradually inwardly contracted from bottom to top to form a second skirt; by setting the second skirt that is gradually inwardly contracted from bottom to top at the lower end of the protective cover, the protective cover can more reliably protect the walking wheel assembly under the action of the second skirt, and in addition, the structural strength and deformation resistance of the protective cover can be further improved under the action of the second skirt, i.e., the deformation of the protective cover can be further reliably avoided when the protective cover is impacted, i.e., the protective cover can reliably protect the walking wheel assembly.

[0011] In a possible implementation, the protective cover on both sides of the convex rib is provided with a plurality of through holes arranged in an upper-to-lower interval; after the structure is adopted, the weight of the protective cover can be reduced, and the structural strength and deformation resistance of the protective cover can be further improved, that is, the deformation of the protective cover can be reliably avoided when the protective cover is impacted, and the protective cover can reliably protect the walking wheel assembly.
