[0054] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0055] like Figure 1 and Figure 2 As shown, the present application provides an X-ray imaging system, which includes an X-ray emitting device 300 and an X-ray receiving device 400. The X-ray emitting device 300 is used to emit X-rays toward an object to be inspected, and the X-ray receiving device 400 is used to receive X-rays that have passed through the object to be inspected and perform imaging. The X-ray emitting device 300 includes a first support assembly 301 and a head assembly 302 disposed on the first support assembly 301. The X-ray receiving device 400 includes a second support assembly 401 and a cassette assembly 402 disposed on the second support assembly 401.

[0056] In this embodiment, if Figure 1 、 Figure 2 、 Figure 4 and Figure 6 As shown, the electromagnetic device 100 includes a contact end 1013, which is used to limit the movement of at least one of the first support component 301, the head component 302, the second support component 401, and the film box component 402 when contacting at least one of the first support component 301, the head component 302, the second support component 401, and the film box component 402, so as to effectively brake at least one of the first support component 301, the head component 302, the second support component 401, and the film box component 402.

[0057] In an optional embodiment, the electromagnetic device 100 further includes a buffer 102, which is convexly arranged at the contact end 1013. The buffer 102 is used to provide a buffer when the contact end 1013 contacts at least one of the first support component 301, the head component 302, the second support component 401, and the cassette component 402, so as to avoid a large impact force when the contact end 1013 contacts at least one of the first support component 301, the head component 302, the second support component 401, and the cassette component 402, so as to make the first support component 301, the head component 302, the second support component 401, and the cassette component 402 At least one of the film box components 402 can contact the contact end 1013 at a very low speed, thereby reducing the sound generated when at least one of the first support component 301, the head component 302, the second support component 401, and the film box component 402 contacts the contact end 1013, which can provide medical staff with a good operating experience and will not affect medical staff and patients. At the same time, it can also avoid the first support component 301, the head component 302, the second support component 401 and / or the film box component 402 from being damaged due to long-term impact force, and will not affect the braking function of the electromagnetic device 100.

[0058] It should be noted that the contact end 1013 of the electromagnetic device 100 refers to the attraction surface when the electromagnetic device 100 contacts at least one of the first support component 301, the head component 302, the second support component 401 and the film box component 402, that is, when the electromagnetic device 100 contacts the first support component 301, the contact end 1013 is the side of the electromagnetic device 100 facing the first support component 301; when the electromagnetic device 100 contacts the head component 302, the contact end 1013 is the side of the electromagnetic device 100 facing the head component 302; when the electromagnetic device 100 contacts the second support component 401, the contact end 1013 is the side of the electromagnetic device 100 facing the second support component 401; when the electromagnetic device 100 contacts the film box component 402, the contact end 1013 is the side of the electromagnetic device 100 facing the film box component 402.

[0059] After adopting the above technical solution, when the electromagnetic device 100 attracts the target object and causes the target object to move, the target object first contacts the buffer and then contacts the contact end 1013. The buffer absorbs the impact force when the target object contacts the contact end 1013, so that the target object does not directly contact the contact end 1013, or the target object only contacts the contact end 1013 at a very low speed, resulting in only slight contact, thereby greatly reducing contact noise, that is, reducing the noise when the target object is braked. At the same time, by avoiding direct contact between the target object and the contact end 1013, the service life and performance of the target object and the electromagnetic device 100 can be improved. The target object includes at least one of the first support assembly 301, the head assembly 302, the second support assembly 401, and the cassette assembly 402.

[0062] In an optional embodiment, if Figures 1 to 4 As shown, the bed 4011 includes a base 4011b and a bed board 4011a. The bed board 4011a is movably mounted on the base 4011b.

The transverse grooves are respectively located on both sides of the vertical groove to form a limit groove for cooperating with the outer flange 10221 and the inner flange 10222, so that the buffer pad can be firmly fixed in the fixing groove 1011. At the same time, the buffer part 1021 can protrude from the contact end 1013 along the direction of the vertical groove, and is used to contact with at least one of the first support component 301, the head component 302, the second support component 401, and the chip box component 402, to provide buffering when the magnetic core 101 contacts with at least one of the first support component 301, the head component 302, the second support component 401, and the chip box component 402.

[0078] In an optional embodiment, the width of the buffer portion 1021 gradually decreases in the direction away from the connecting portion, so that the buffer portion 1021 can have different elastic resistances at different positions, so that the buffer portion 1021 can be instantly deformed when it contacts at least one of the first support component 301, the head component 302, the second support component 401, and the cassette component 402, and then gradually reduces the deformation of the buffer portion 1021 as the contact area between the buffer portion 1021 and at least one of the first support component 301, the head component 302, the second support component 401, and the cassette component 402 increases, thereby greatly reducing the deformation of the first support component 301, the head component 302, The impact force of at least one of the second support component 401 and the film box component 402 prevents at least one of the first support component 301, the head component 302, the second support component 401, and the film box component 402 from contacting the magnetic core 101, or contacts the magnetic core 101 only at a very small speed, thereby avoiding or reducing the generation of noise, thereby ensuring the buffering effect of the buffer part 1021, and also reducing the possible damage caused by the impact force of at least one of the first support component 301, the head component 302, the second support component 401, and the film box component 402 on the magnetic core 101; at the same time, it also ensures the thickness and hardness of the connecting part to avoid separation of the connecting part from the magnetic core 101.

[0079] It should be noted that the gap between the magnetic core 101 and at least one of the first support assembly 301, the head assembly 302, the second support assembly 401, and the film box assembly 402 is related to the protrusion and hardness of the buffer part 1021. Therefore, the present application can meet the use requirements of different gaps by adjusting the protrusion and hardness of the buffer part 1021.

[0080] In an optional embodiment, the height difference between the buffer portion 1021 and the contact end 1013 is no greater than 1 mm. The contact end 1013 refers to the surface of the magnetic core 101 that contacts at least one of the first support assembly 301, the head assembly 302, the second support assembly 401, and the cassette assembly 402. The distance between the contact end 1013 and the top of the buffer portion 1021 that first contacts at least one of the first support assembly 301, the head assembly 302, the second support assembly 401, and the cassette assembly 402 is no greater than 1 mm. This allows the elastic deformation of the buffer portion 1021 to minimize the gap, limit the deformation of the buffer portion 1021, avoid excessive deformation of the buffer portion 1021, thereby suppressing elastic degradation, and suppressing the generation of abnormal noise through buffering, thereby preventing the generation of abnormal noise.

[0081] In an optional embodiment, the buffer portion 1021 protrudes from the contact end 1013 of the magnetic core 101, and the amount of protrusion is set according to the amount of compression of the buffer portion 1021 absorbed by the gap, so that after the buffering operation is performed by the compression of the buffer portion 1021, a portion of the buffer portion 1021 can contact at least one of the first support assembly 301, the head assembly 302, the second support assembly 401, and the chip box assembly 402, so as to stably adjust the relative position of the magnetic core 101 and at least one of the first support assembly 301, the head assembly 302, the second support assembly 401, and the chip box assembly 402 when the magnetic core 101 contacts at least one of the first support assembly 301, the head assembly 302, the second support assembly 401, and the chip box assembly 402.

[0082] In an optional embodiment, the height difference between the buffer portion 1021 and the contact end 1013 is preferably 0.3 mm. This not only reduces the gap between the magnetic core 101 and at least one of the first support assembly 301, the head assembly 302, the second support assembly 401, and the cassette assembly 402, but also reduces the electromagnetic attraction force between the magnetic core 101 and at least one of the first support assembly 301, the head assembly 302, the second support assembly 401, and the cassette assembly 402 during braking, but also prevents excessive elastic deformation of the buffer portion 1021. The maximum electromagnetic attraction force of the magnetic core 101 is greater than the compressive force of the buffer portion 1021, so that at least one of the first support assembly 301, the head assembly 302, the second support assembly 401, and the cassette assembly 402 can be effectively braked.

[0083] In an optional embodiment, the buffer pad is made of rubber material.

[0084] In an optional embodiment, the buffer pad has high temperature resistance and a wear-resistant layer is formed on its outer side so that the buffer pad can have good elastic properties to achieve the functions and purposes of quietness and shock absorption. It can also play a role in high temperature resistance and can be affected by high temperatures and damaged. It can also avoid the wear caused by the contact between the magnetic core 101 and at least one of the first support component 301, the head component 302, the second support component 401, and the film box component 402.

[0085] In an optional embodiment, the buffer pad is made of fluororubber, which has good thermal stability and wear resistance. It can not only withstand the influence of high temperature, but also avoid the wear caused by the contact between the magnetic core 101 and at least one of the first support component 301, the head component 302, the second support component 401, and the film box component 402.

[0086] In an optional embodiment, the top of the buffer pad is a flat structure or a slightly arched arc structure, and the flat structure or arc structure can be constructed to have a friction surface for contacting at least one of the first support assembly 301, the head assembly 302, the second support assembly 401, and the film box assembly 402, so that through the softness of the buffer pad, when at least one of the first support assembly 301, the head assembly 302, the second support assembly 401, and the film box assembly 402 is braked, the buffer pad can maintain good contact with at least one of the first support assembly 301, the head assembly 302, the second support assembly 401, and the film box assembly 402, which can not only reduce the noise of at least one of the first support assembly 301, the head assembly 302, the second support assembly 401, and the film box assembly 402 when braking, but also can quickly stop at least one of the first support assembly 301, the head assembly 302, the second support assembly 401, and the film box assembly 402 at the corresponding position, thereby achieving precise control.

[0087] In an optional embodiment, the buffer portion 1021 has a convex structure of different heights, so that the buffer portion 1021 can have different elastic properties, and thus the buffer portion 1021 can have different buffering properties. At the same time, the convex structure can also increase the friction between the buffer portion 1021 and at least one of the first support component 301, the head component 302, the second support component 401, and the film box component 402.

[0088] In an optional embodiment, the hardness of the cushion is between 50 and 70 degrees, which can take into account the toughness, rebound effect and impact cushioning effect of the cushion. The hardness of the cushion is preferably 60 degrees.

[0089] In an optional embodiment, an exhaust structure is provided on the buffer 102, which is arranged on the buffer portion 1021 of the buffer 102 and passes through the inner and outer sides of the buffer 102, so that air can be discharged when pressure is applied to the buffer, thereby preventing the air inside the buffer 102 from being unable to be discharged when pressure is applied to the buffer 102, thereby causing noise.

[0090] In an optional embodiment, the exhaust structure includes exhaust holes 1023 symmetrically arranged on both sides of the buffer 102, and the bottom of the exhaust holes 1023 is lower than the contact end 1013, so that when pressure is applied to the buffer, the air inside the buffer 102 can be quickly discharged from the exhaust holes 1023.

[0091] In an optional embodiment, an abutment portion 1012 is provided on the shell for abutting the reset member 202, and the abutment portion 1012 extends radially outward toward the shell so that the reset member 202 can always maintain an elastic force in the direction of the abutment portion 1012 to drive the electromagnetic device 100 to move in a direction away from the metal component.

[0092] In an optional embodiment, if Figures 1 to 4 As shown, the X-ray imaging system also includes a mounting component 200, which includes a reset member 202 and a support structure 201.

One end of the reset member 202 abuts against the support structure 201, and the other end of the reset member 202 abuts against the electromagnetic device 100, so that the reset member 202 can always maintain an elastic force in the direction of the abutting portion 1012 to drive the electromagnetic device 100 to move in a direction away from the metal component.

[0093] In an optional embodiment, the support structure 201 includes a connecting support 2011 and a fixed support 2012. The fixed support 2012 is connected to the connecting support 2011 and is provided with a guide groove 201b.

The guide groove 201b can limit the axial movement of the electromagnetic device 100, thereby making the operation of the electromagnetic device 100 smoother, avoiding the formation of contact noise, and reducing noise.

[0094] Exemplarily, the fixing bracket 2012 is U-shaped, with guide grooves 201b provided on both sides of the fixing bracket 2012 in the vertical direction. A through-hole structure 201a is provided on the side of the fixing bracket 2012 facing the metal component. The inner diameter of the through-hole structure 201a matches the outer diameter of the electromagnetic device 100, allowing the electromagnetic device 100 to be inserted into the through-hole structure 201a. At the same time, both ends of the electromagnetic device 100 are movably connected to the guide grooves 201b via the abutment portions 1012. In this embodiment, the reset member 202 is a spring member, one end of which abuts against the outer peripheral side of the through-hole structure 201a, and the other end of the spring member abuts against the abutment portion 1012, so that the electromagnetic device 100 always maintains an elastic force in the direction of the abutment portion 1012, thereby driving the electromagnetic device 100 to move away from the metal component.

[0095] In an optional embodiment, the mounting component 200 includes a roller assembly 203, which is mounted on the connecting bracket 2011 and located on both sides of the electromagnetic device 100.

[0096] In an optional embodiment, there are two electromagnetic devices 100, and the two electromagnetic devices 100 are arranged at intervals along the length direction of the connecting bracket 2011. The roller assembly 203 is arranged on the opposite side of the two electromagnetic devices 100.

In addition, the electromagnetic device 100 can also be directly installed on at least one of the first support column 301a, the suspension structure 301b, the bed 4011, the second support column 4012, the film box assembly 402 and the head assembly 302, without the need for connection through the fixed bracket 2012 and the connecting bracket 2011; or, the electromagnetic device 100 can also be connected to at least one of the first support column 301a, the suspension structure 301b, the bed 4011, the second support column 4012, the film box assembly 402 and the head assembly 302 through the connecting bracket 2011, and this application is not limited to this.
