[0044] The hinge assembly 220 further includes a rotation groove 222 provided on the first hinge member 221, a hinge shaft 223 is provided on the second hinge member 224, the hinge shaft 223 is rotatably connected in the rotation groove 222, and two first arc-shaped arms 230 are respectively connected to the first hinge member 221 and the second hinge member 224 by bolts 225;

[0045] The first hinge member 221 is provided with a first rotating shaft 226, and the second hinge member 224 is provided with a second rotating shaft 227. The first rotating shaft 226 and the second rotating shaft 227 are both rotatably connected to the arc seat 210, and the hinge shaft 223, the first rotating shaft 226 and the second rotating shaft 227 are all coaxial.

[0046] In this embodiment: Figure 1 In the coordinate system established in , the X-axis is the left-right direction, the Z-axis is the front-back direction, and the Y-axis is the up-down direction. The C-arm is a semicircular structure, with an X-ray generator 120 and a detector 130 mounted at both ends. The X-ray generator 120 can generate X-rays, which pass through the human body and reach the detector 130. The detector 130 can receive the X-rays and use the property of differential absorption to distinguish soft tissues such as bones, muscles, fat, etc. with different densities.

[0047] Specifically, the arc seat 210 is rotatable along the Z-axis direction, and the first hinge 221 of the hinge assembly 220 installed in the middle of the arc seat 210 is located at the lower side, and the second hinge 224 is located at the upper side. The two first arc arms 230 installed on the first hinge 221 and the second hinge 224 form a C-shaped arm. The first hinge 221 and the second hinge 224 can rotate based on the Z-axis direction axis of the first rotating shaft 226, the hinge shaft 223, and the second rotating shaft 227.

[0048] When the first hinge 221 rotates clockwise and the second hinge 224 rotates counterclockwise, and the rotation amplitudes of the two are the same, the two first arc-shaped arms 230 expand, and the radius of the circular track of the C-shaped arm increases.

[0049] Similarly, when the first hinge 221 rotates counterclockwise and the second hinge 224 rotates clockwise, and the rotation amplitudes of the two are the same, the two first arc-shaped arms 230 contract, and the radius of the circular track of the C-shaped arm is reduced.

[0050] Embodiment 2: This embodiment is an improvement on Embodiment 1. For details, please refer to Figure 1-Figure 10 The first rotating assembly 240 includes a first motor 241 disposed on the arc seat 210, a first bevel gear 242 is disposed on the output shaft of the first motor 241, two third rotating shafts 243 are rotatably disposed on the arc seat 210, and a second bevel gear 244 is disposed on each of the two third rotating shafts 243. The two second bevel gears 244 are symmetrical based on the first bevel gear 242, and the two second bevel gears 244 are both meshed with the first bevel gear 242;

[0051] The two third rotating shafts 243 are each provided with a first pulley 245, the two first rotating shafts 226 are each provided with a second pulley 246, the first rotating assembly 240 further includes two first transmission belts 247, and the two first pulleys 245 are respectively connected to the two second pulleys 246 through the two first transmission belts 247;

[0052] The first rotating shaft 226 and the second rotating shaft 227 rotate at the same speed, and the first rotating shaft 226 and the second rotating shaft 227 rotate in opposite directions.

[0053] In this embodiment, the first hinge 221 and the second hinge 224 are controlled to rotate in opposite directions by the first rotating assembly 240. When the first motor 241 drives the first bevel gear 242 to rotate clockwise, the second bevel gear 244 and the third rotating shaft 243 located in front of the first motor 241 rotate clockwise, while the second bevel gear 244 and the third rotating shaft 243 located in the rear of the first motor 241 rotate counterclockwise.

[0054] The belt transmission device composed of the first pulley 245, the second pulley 246 and the first transmission belt 247 has the same transmission ratio, and the diameters of the first rotating shaft 226 and the second rotating shaft 227 are also the same. Therefore, the rotation speeds of the first rotating shaft 226 and the second rotating shaft 227 are the same, and the rotation directions are opposite. Then the first hinge 221 and the first arc-shaped arm 230 located at the lower side will rotate clockwise, and the second hinge 224 and the first arc-shaped arm 230 located at the upper side will rotate counterclockwise at the same speed. The radius of the circular track increases.

[0055] Similarly, when the first motor 241 drives the first bevel gear 242 to rotate counterclockwise, the first hinge 221 and the first arc arm 230 on the lower side will rotate counterclockwise, and the second hinge 224 and the first arc arm 230 on the upper side will rotate clockwise at the same speed, and the radius of the circular track will decrease.

[0056] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-Figure 7 , the C-arm mechanism 200 further includes a second rotating assembly 250, and the second rotating assembly 250 is used to drive the arc seat 210 to rotate along the Z axis;

[0057] The second rotating assembly 250 includes a second motor 251 disposed in the first swing arm 110 . A first spur gear 252 is disposed on the output shaft of the second motor 251 . A first arc-shaped rack 253 is disposed on the arc seat 210 . The first spur gear 252 meshes with the first arc-shaped rack 253 .

[0058] In this embodiment: the second rotating assembly 250 is used to control the overall rotation of the C-arm mechanism 200 based on the Z axis. When the second motor 251 drives the first spur gear 252 to rotate clockwise, the first arc-shaped rack 253 with teeth located on the outer arc surface and the arc seat 210 will rotate counterclockwise. When the second motor 251 drives the first spur gear 252 to rotate counterclockwise, the first arc-shaped rack 253 with teeth located on the outer arc surface and the arc seat 210 will rotate clockwise.

[0059] Embodiment 4: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-Figure 10 The two first arc-shaped arms 230 are each provided with an arc-shaped slide groove 260, and the second arc-shaped arms 270 are slidably arranged in the two arc-shaped slide grooves 260. The X-ray generating device 120 and the detector 130 are respectively connected to the two second arc-shaped arms 270. The first arc-shaped arm 230 and the second arc-shaped arm 270 form a retractable arc structure. The C-shaped arm mechanism 200 also includes a retractable assembly 280;

[0060] When the first hinge 221 and the second hinge 224 rotate in opposite directions and the distance between the two first arc-shaped arms 230 increases, the telescopic assembly 280 controls the two arc-shaped structures to extend;

[0061] When the first hinge 221 and the second hinge 224 rotate in opposite directions and the distance between the two first arc-shaped arms 230 decreases, the telescopic assembly 280 controls the two arc-shaped structures to shorten;

[0062] The telescopic assembly 280 includes two fourth rotating shafts 281 symmetrically arranged on the X-axis and Y-axis planes. The two fourth rotating shafts 281 are rotatably arranged on the two first arc-shaped arms 230, respectively. The two fourth rotating shafts 281 are each provided with a second spur gear 282. The two second arc-shaped arms 270 are each provided with a second arc-shaped rack 283. The two second arc-shaped racks 283 are respectively meshed with the two second spur gears 282.

[0063] The telescopic assembly 280 further includes two third pulleys 284 that are plane-symmetrical based on the X-axis and the Y-axis, and the two third pulleys 284 are respectively disposed on the first rotating shaft 226 and the second rotating shaft 227;

[0064] The two fourth rotating shafts 281 are both provided with fourth pulleys 285 . The telescopic assembly 280 further includes two second transmission belts 286 . The two third pulleys 284 are respectively connected to the two fourth pulleys 285 through the two second transmission belts 286 .

[0065] In this embodiment, when the two first arc-shaped arms 230 are distributed based on a circle, the X-ray generator 120 and the detector 130 can be aligned and connected in a straight line. When the radius of the circular track increases or decreases, the X-ray generator 120 and the detector 130 are no longer aligned. Therefore, a telescopic assembly 280 is provided.

[0066] Specifically, when the radius of the circular track increases, the first rotating shaft 226 rotates clockwise, and the fourth rotating shaft 281 and the second spur gear 282 located at the lower side rotate clockwise through the transmission of the belt transmission device composed of the third pulley 284, the fourth pulley 285 and the second transmission belt 286, thereby causing the second arc-shaped rack 283 with teeth located on the inner arc surface to rotate clockwise. The clockwise rotation of the second arc-shaped rack 283 at the lower side causes the second arc-shaped arm 270 at the lower side to extend based on the first arc-shaped arm 230.

[0067] The second rotating shaft 227 rotates counterclockwise, and through the transmission of another set of belt transmission devices, the fourth rotating shaft 281 and the second spur gear 282 on the upper side rotate counterclockwise, thereby causing the second arc-shaped rack 283 on the upper side to rotate counterclockwise, so that the second arc-shaped arm 270 on the upper side is extended based on the first arc-shaped arm 230.

[0068] Similarly, when the track radius decreases, the two second arc-shaped arms 270 are shortened based on the two first arc-shaped arms 230 respectively.

[0069] Thereby, the X-ray generator 120 and the detector 130 can still be kept aligned in a straight line.

Four pulleys 180 are installed at the bottom of the X-ray machine body 100 .

[0072] In this embodiment, the electrical components inside the X-ray machine body 100 transmit power, instructions and / or data to the X-ray generator 120 and the detector 130 through the cable 170. The control panel 160 then displays and outputs the images based on the obtained data.

[0073] The X-ray machine body 100 can move on the ground based on four pulleys 180. In addition, multi-dimensional motion control is provided for the C-arm mechanism 200.

[0074] The various components of the X-ray machine body 100 are conventional technical means, and their specific structures and working principles are not described in detail.

[0075] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
