[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1-2 As shown, a mobile C-arm DR device comprises a base 1 and a C-arm 2 mounted on the base 1, wherein the C-arm 2 is driven by a driving mechanism 3 disposed in the base 1;

[0028] The driving mechanism 3 at least comprises:

[0029] The components driving the C-shaped arm 2 to rotate along the X-axis are:

[0030] The track frame 33 is slidably arranged on the guide rail member 21 installed in the groove opened on the back of the C-shaped arm 2, and the track frame 33 has at least two balls 4 and guide rollers 5 that are rollingly connected to the opposite surfaces of the guide rail member 21. The track frame 33 here is provided with a main shaft member 6 that penetrates into the machine base 1, and the main synchronous wheel 61 that is rotatably arranged in the main shaft member 6 is connected to the two guide rollers 5 through a synchronous belt transmission, and the outer wall of the flying disc 70 at the output end of the driving motor 31 is provided with a plurality of round rods arranged in a circumferential array, and the end surface of the driven wheel 322 that is rotatably arranged in the machine base 1 is provided with a plurality of round rods arranged in a circumferential array, and the flying disc 70 and the round rods on the driven wheel 322 cooperate with each other to realize transmission;

[0031] The component that drives the C-arm 2 to rotate around the Y axis, specifically:

[0032] The hydraulic telescopic rod 11 is fixedly installed in the machine base 1, and the main shaft 6 is fixedly connected to the rotating shaft 32 through the flange, and is rotatably connected to the output end of the hydraulic telescopic rod 11 in the machine base 1 through the rotating shaft 32, so the hydraulic telescopic rod 11 can drive the main shaft 6 to move downward, thereby releasing the coupling relationship between the flying disc 70 and the driven wheel 322. The outer wall of the rotating shaft 32 is fixedly installed with a non-standard gear 321 that meshes with the circular gear 311 at the output end of the driving motor 31, so the tooth opening of the end face of the non-standard gear 321 that moves downward will mesh with the tooth surface of the circular gear 311.

[0033] In the above technology, the driving motor 31 in the driving mechanism 3 is used to realize the circumferential rotation of the C-arm 2 along the X-axis and the Y-axis, thereby realizing rotation in at least two directions to increase the need to adapt to changes in the human body curve during the imaging process.
