A vehicle-mounted mobile CT apparatus according to the present invention will be described in detail with reference to the accompanying drawings. The features of the following examples and embodiments may be combined with each other without conflict.

Referring to fig. 1 to 5, a vehicle-mounted mobile CT apparatus 100 is mounted on a mobile vehicle, and includes a CT apparatus and a damping mechanism 1 for fixing the CT apparatus to the vehicle. The damping mechanism 1 includes a limiting member 2 and a damping member 3 assembled together. The limiting member 2 includes a first limiting member 20 assembled with the CT machine and a second limiting member 21 assembled with the vehicle floor. The damping member 3 is disposed between the first limiting member 20 and the second limiting member 21. This application is through the reasonable combination of bumper shock absorber 3 with locating part 2, and compact structure appearance is pleasing to the eye and ensures the security of CT machine under the special operating mode in the transportation.

In an embodiment, the damping member 3 is provided with a plurality of first assembling holes 30 adapted to the first limiting member 20 and a plurality of second assembling holes 31 adapted to the second limiting member 21. The first assembling nut 301 is embedded in the first assembling hole 30, and the second assembling nut 311 is embedded in the second assembling hole 31. The first stopper 20 and the damper 3 are flexibly connected by a first screw 32 assembled with the first assembly hole 30, and the second stopper 21 and the damper 3 are flexibly connected by a second screw 33 assembled with the second assembly hole 31. The first assembling nut 301 and the second assembling nut 311 are nuts pre-embedded in the damper 3 to ensure the reliability of the assembly of the first limiting member 20 and the second limiting member 21 with the damper 3 through the first screw 32 and the second screw 33. In this embodiment, the first assembling hole 30 and the second assembling hole 31 are annularly arranged on the shock absorbing member 3 to enhance the force-bearing capability of the shock absorbing mechanism 1.

The center of the shock absorbing member 3 is provided with a positioning hole 34 penetrating through the shock absorbing member 3. A screw hole 210 is disposed at a position of the second limiting member 21 corresponding to the positioning hole 34, and a concave portion 201 is disposed at a position of the first limiting member 20 corresponding to the positioning hole 34. The recess 201 is provided with a through hole 202, and the positioning column 22 passes through the through hole 202, the positioning hole 34 and the screw hole 210 from top to bottom to assemble the first limiting member 20, the damping member 3 and the second limiting member 21 into a whole. The diameter of the through hole 202 allows the positioning post 22 to pass through smoothly.

The positioning post 22 includes a first assembling portion 220 adapted to the through hole 202 and a second assembling portion 221 adapted to the screw hole 210, and a radial dimension of the second assembling portion 221 is larger than a radial dimension of the first assembling portion 220. The second assembling portion 221 is interference-fitted with the screw hole 210. The second assembly portion 221 and the screw hole 210 are in interference fit, so that the second limiting member 21 and the positioning column 22 can be prevented from being loosened, and the overall installation reliability of the equipment is ensured.

A limiting plate 222 is disposed at the top end of the first assembling portion 220, a first gap W is formed between the radial outer edge of the limiting plate 222 and the inner wall of the recess 201, and a second gap H is formed between the bottom surface of the limiting plate 222 and the bottom wall of the recess 201. The first gap W is used for absorbing external force impact on the CT machine in the horizontal direction, and the second gap H is used for absorbing external force impact on the CT machine in the vertical direction. When emergency braking occurs or the road surface greatly bumps, the first gap and the second gap are arranged, so that the deformation of the damping piece 3 is increased, and the buffering effect is enhanced.

The width of the first gap W is more than or equal to 3mm and less than or equal to 6mm, and the height of the second gap H is more than or equal to 3mm and less than or equal to 6 mm. The width of the first gap and the height of the second gap are both set to limit the flexible connection between the damping member 3 and the first limiting member 20 and the second limiting member 21 within a certain range, and beyond this range, the damping member 3 and the first limiting member 20 and the second limiting member 21 form hard contact to ensure safety.

The shock absorbing member 3 is a circular rubber plate, and the first assembling holes 30 and the second assembling holes 31 are alternately arranged. The damping member 3 is a circular rubber plate, which can prevent stress concentration caused in the deformation process, and the first assembling holes 30 and the second assembling holes 31 are alternately arranged to ensure the stress balance of the first limiting member 20 and the second limiting member 21, so that the stress of the damping mechanism 1 is kept balanced. Indeed, for the overall aesthetic property of the device, a frame-shaped partition plate may be disposed at the periphery of the damping mechanism and assembled with the frame of the CT machine to shield the damping mechanism.

The first limiting member 20 is provided with a tongue plate 203 for assembling with a CT machine. A third assembling hole 204 is formed in the tongue plate 203, and a screw passing through the third assembling hole 204 assembles the first limiting member 20 to the CT machine. A fourth assembly hole 211 is formed in the second limiting member 21, the fourth assembly hole 211 is located on the periphery of the second assembly hole 31, and a screw passing through the fourth assembly hole 211 assembles the second limiting member 21 to a vehicle floor. In this embodiment, the first limiting member 20 includes a substantially circular main body, and the tongue plate 203 protrudes outward from the main body to facilitate assembling the damping mechanism 1 with the CT machine. The fourth assembling hole 211 provided in the second limiting member 21 facilitates assembling the damping mechanism 1 on a carrier vehicle.

Referring to fig. 6 and 7, in another embodiment, the damping member 3 includes a first assembling surface 35 assembled with the first limiting member 20 and a second assembling surface 36 assembled with the second limiting member. The first assembly surface 35 and the second assembly surface 36 are connected by an arc-shaped buffer portion 37. The shock absorbing member 3 is made of hollow rubber. In the present embodiment, the first assembly surface 35 and the second assembly surface 36 are arranged in parallel and have the same radial dimension. The shock absorbing member 3 is substantially in the shape of a hollow cylindrical structure with two small ends and a large middle to absorb external force impact in the carrying process of the CT machine.

Specifically, the radial dimension of the first assembling surface 35 and the radial dimension of the second assembling surface 36 are both smaller than the radial dimension of the arc-shaped buffer portion 37.

In the two embodiments disclosed in the present application, the damping mechanisms are symmetrically disposed at the bottom of the CT machine, and the number of the damping mechanisms is at least four to ensure the damping effect and the stress balance between the CT machine and the vehicle-mounted device.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
