[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1-5 As shown, a mobile base for an intelligent robot includes a chassis 1, with wheels 3 mounted on both sides of the chassis 1 via steering brackets 2.

[0026] The upper part of the chassis 1 is provided with a protective component 4 for protecting the steering bracket 2 and the wheels 3;

[0027] Mounting columns 5 for mounting shelves are fixedly installed on the upper surface of the chassis 1.

[0028] The protective component 4 includes a mounting frame 401, which is located on one side of the chassis 1. Each side of the mounting frame 401 is fixedly mounted with a mounting bracket 402. Each mounting bracket 402 has a stepped groove 403 on its lower surface. A circular plate 404 is movably arranged in the stepped groove 403. A sliding column 405 is fixedly mounted on the lower surface of each circular plate 404. A bracket 406 is fixedly mounted at the lower end of each sliding column 405. A lifting frame 407 is fixedly mounted at one end of each bracket 406. A protective cover 408 is provided on the lower surface of the lifting frame 407.

[0029] Each stepped groove 403 is provided with several elastic elements 409 that can be compressed and reset.

[0030] The elastic element 409 is a spring.

[0031] By installing radar and smart camera on one side of chassis 1, chassis 1 can easily detect the surrounding environment. In conjunction with self-driven steering bracket 2 and wheels 3, chassis 1 can move intelligently. When protective cover 408 is hit, circular plate 404 moves along stepped groove 403. Spring force is applied to buffer the impact on protective cover 408, so that protective cover 408 can block the impact and prevent foreign objects from directly colliding with steering bracket 2 and wheels 3, thus preventing collision between steering bracket 2 and wheels 3.

[0032] In another embodiment of the present invention, a sliding groove 6 is provided on both sides of the chassis 1, and a slider 601 is slidably arranged in both sliding grooves 6. A lead screw 7 is rotatably installed between the two sides of the inner wall of one of the sliding grooves 6, and the corresponding slider 601 is threaded on one side of the lead screw 7.

[0033] A positioning rod 8 is fixedly installed between the two sides of the inner wall of another slide 6, and the corresponding slider 601 is slidably set on one side of the positioning rod 8.

[0034] The upper end of the lead screw 7 passes through the corresponding slide groove 6 and is fixedly installed with a hexagonal block 9.

[0035] Workers rotate hexagonal block 9, which drives lead screw 7 to rotate. The rotating lead screw 7 drives slider 601 to move along positioning rod 8 by screwing in. The moving slider 601 drives lifting frame 407 and protective cover 408 to rise, making it easier for workers to maintain steering bracket 2 and wheel 3.

[0036] In another embodiment of this utility model, the protective cover 408 is fixedly installed on the lower surface of the lifting frame 407 by bolts 10.

[0037] By setting bolt 10, it is convenient for staff to quickly disassemble and install the damaged protective cover 408, making it easy to replace.

[0038] The working principle of this intelligent robot mobile base:

[0039] In use, by setting up radar and smart camera on one side of chassis 1, chassis 1 can detect the surrounding environment. In conjunction with self-driven steering bracket 2 and wheels 3, chassis 1 can move intelligently. When the protective cover 408 is hit, the circular plate 404 moves along the stepped groove 403. The spring is stressed to buffer the impact on the protective cover 408, so that the protective cover 408 can block the impact and prevent foreign objects from directly colliding with the steering bracket 2 and wheels 3, thus preventing the steering bracket 2 and wheels 3 from colliding.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
