The wheel body 9 is accommodated between the first wall 2 and the second wall 3, and the wheel body 9 is rotatably connected to the vehicle body 1, and the wheel body 9 is a Mecanum wheel.

[0027] The mobile chassis of the embodiment of the present application can be used to install the RCS detector, so that the RCS detector can be moved.

[0028] The first direction may be the direction shown by the X-axis in the figure, the second direction may be the direction shown by the Y-axis in the figure, and the first direction and the second direction may be the horizontal directions shown in the figure.

[0029] The wheel body mounting portion 4 is used to form a position for mounting the wheel body 9, that is, the position between the first wall 2 and the second wall 3 is used to accommodate the wheel body 9, so as to isolate the wheel body 9 from other components arranged on the mobile chassis.

[0030] The outer wall 7 can protect the vehicle body 1. Specifically, the arc surface segment 5 enables the straight surface segment 6 to be spaced apart from the second wall 3, thereby enabling the outer wall 7 to protect the vehicle body 1.

[0031] There may be four wheel bodies 9, which are arranged in two rows along the first direction, with two wheel bodies in each row, and the wheel bodies 9 in each row are arranged at intervals along the second direction.

[0032] The wheel body 9 is a Mecanum wheel, so that the vehicle body 1 can complete multiple movement modes such as straight travel, on-the-spot turning and lateral movement, thereby increasing the movement flexibility of the vehicle body 1.

[0033] The structure and working principle of the Mecanum wheel are well known to those skilled in the art and will not be described in detail here.

[0034] See also Figure 2 In some embodiments, the first wall 2 and the second wall 3 are respectively provided with a plurality of first through holes 8, and the plurality of first through holes 8 are spaced apart along the second direction.
