Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-4As shown, a modular robot chassis comprises: two chassis frames 1, two moving wheels 2 are rotatably installed on the sides of the two chassis frames 1 that are away from each other; an assembly reinforcement mechanism 3, the assembly reinforcement mechanism 3 for assembling and adjusting the spacing between the two chassis frames 1 is arranged between the two chassis frames 1; wherein the assembly reinforcement mechanism 3 comprises a connecting frame 31 fixedly installed on the adjacent side of the two chassis frames 1, a combination component 32 is arranged between the two connecting frames 31, and an adjustment component 33 is arranged on one side of the connecting frame 31, and the two chassis frames 1 can be connected to the combination component 32 through the corresponding connecting frame 31, so that the chassis frames 1 can be used, and when it is necessary to adjust the placement space of the two chassis frames 1, the placement space between the two chassis frames 1 can be increased through the combination component 32, so that the robot chassis can flexibly adjust its width and placement space according to different application requirements and environmental conditions when in use, so as to facilitate adaptation and installation of modules of different sizes, and the adjustment component 33 can adjust the bracket space on one side of the two connecting frames 31, so that objects of different sizes can be placed.

[0024] like Figure 2 , Figure 3 and Figure 4As shown, the combined assembly 32 includes a plurality of combined plates 321 arranged between two connecting frames 31, and the bottoms of the plurality of combined plates 321 are each provided with two first connecting grooves 322, and the interior of the first connecting grooves 322 is fixedly installed with a connecting plate 323, and one side of the connecting plate 323 of the plurality of combined plates 321 extends to the interior of the adjacent first connecting grooves 322. When installing, a suitable number of combined plates 321 are selected to be combined with each other, and then connected with the two connecting frames 31. When the two combined plates 321 are connected with each other, one side of the combined plate 321 can be brought close to the other combined plate 321, and the connecting plate 323 can be extended to the first side of the other combined plate 321. The connection can be quickly made inside the first connecting groove 322, which is very convenient. The volume of the connecting plate 323 gradually increases from bottom to top. The shape of the first connecting groove 322 is adapted to the connecting plate 323. The cross-section of the connecting plate 323 is an inverted isosceles trapezoid. After the connecting plate 323 of this shape is connected with the first connecting groove 322 adapted to the shape, the contact area is increased to improve the connection stability. A limiting block 325 is slidably installed on one side of the combined plate 321. The limiting block 325 is set in an inverted "U" shape. Two limiting grooves 327 are provided on the surface of the connecting plate 323. The two connecting plates 323 are respectively located on one side of the two first connecting grooves 322, and the connecting plate 32 The first and second connecting grooves 322 are connected to the connecting frame 31 on one side, and the second connecting grooves 324 are formed on the surface of the connecting frame 31 on one side. The second connecting grooves 324 are matched with the connecting plate 323 in shape. When the connecting plate 323 enters the first connecting groove 322 of another combined plate 321, the limiting block 325 must be picked up first. After the connecting plate 323 of the other combined plate 321 enters the corresponding first connecting groove 322, the limiting block 325 is reset. At this time, one side of the limiting block 325 will penetrate at the same time and be located in the same first connecting groove 322. The two limiting grooves 327 on the adjacent sides of the two internal connecting plates 323 can reinforce the connection between the two combined plates 321, making it more stable when in use, and the combined plates 321 can also be extended to the second connecting groove 324 of the connecting frame 31 through the connecting plate 323 for combined connection, which is very convenient. Two rubber rings 326 are fixedly installed on one side of the limiting block 325, and the rubber ring 326 is used in conjunction with the limiting groove 327. After the limiting block 325 passes through the limiting groove 327, the rubber ring 326 is also located below the limiting groove 327. The rubber ring 326 can provide additional friction and buffering to further enhance the stability of the connection.

Two sliders 333 are fixedly installed on one side of the support plate 331, and the two sliders 333 are slidably connected to the adjacent connecting frames 31. Through the two sliders 333, the support plate 331 can move smoothly along the connecting frame 31, so that it is more stable when the position of the support plate 331 is adjusted by the screw rod 332.

[0026] When the utility model is in use, during installation, an appropriate number of combination plates 321 are selected to be combined with each other, and then connected with the two connecting frames 31. When the two combination plates 321 are connected to each other, one side combination plate 321 can be moved close to the other combination plate 321, and the connecting plate 323 can be extended to the inside of the first connecting groove 322 of the other combination plate 321, so that the connection can be quickly made. When the connecting plate 323 enters the inside of the first connecting groove 322 of the other combination plate 321, the limiting block 325 needs to be picked up first, and after the connecting plate 323 of the other combination plate 321 enters the inside of the corresponding first connecting groove 322, the limiting block 325 is reset. At this time, one side of the limiting block 325 will penetrate at the same time, and the two parts located in the same first connecting groove 322 will be connected. The two limiting grooves 327 on the adjacent side of the connecting plate 323 can reinforce the connection between the two combined plates 321, making it more stable when in use, and the combined plate 321 can also be extended through the connecting plate 323 to the inside of the second connecting groove 324 of the connecting frame 31 for combined connection, which is very convenient. After the limiting block 325 passes through the limiting groove 327, the rubber ring 326 is also located below the limiting groove 327. The rubber ring 326 can provide additional friction and buffering to further enhance the stability of the connection.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
