[0076] Current electromagnetic brake systems generally do not experience jamming when installed vertically. Vertical installation means that the floating component of the electromagnetic brake system floats in the same direction as gravity. However, jamming is more likely to occur when the electromagnetic brake system is installed horizontally. Horizontal installation means that the floating component of the electromagnetic brake system floats perpendicular to the direction of gravity. When the electromagnetic brake system is installed horizontally, the floating component is subject to not only the horizontal elastic force but also the vertical force of gravity. This creates a tilting force on the floating component that is not parallel to the floating direction, making it prone to jamming during the floating process. For example, in X-ray imaging equipment, an electromagnetic brake device is installed on the pulley connected to the ground rail. In order to achieve the miniaturization and lowness of the ground rail, the electromagnetic brake device needs to be installed horizontally. When the electromagnetic brake device floats in a horizontal state, its floating direction is perpendicular to the direction of gravity, which causes the electromagnetic brake device to easily get stuck during the brake locking and brake unlocking process. The jamming will affect the realization of the brake locking and brake unlocking functions, and the jamming will also produce abnormal noise, affecting the user experience.

[0077] Based on the above analysis, the present application sets a guide structure on the electromagnetic brake device. The guide direction of the guide structure is parallel to the floating direction. The guide structure is used to extend the contact surface length of the floating component in the floating direction. The contact surface is a surface contact. Compared with the point-line contact in the state without a guide structure, the surface contact formed by the guide structure can form a surface support in the floating direction, so that the floating component can float stably along the guide direction of the guide structure, that is, it can float along the floating direction, avoid the tilt of the floating component, and thus eliminate the jamming of the floating component during the floating process.

[0078] In some embodiments, the electromagnetic brake device is further provided with a two-stage floating structure, and the two-stage floating structures have parallel floating directions and opposite passive driving forces. The electromagnetic brake device includes an electromagnetic module that can turn the electromagnetic attraction force on and off by switching the power on and off. The attraction force of the electromagnetic module can be used to achieve electromagnetic braking. The primary floating structure is used to drive the secondary floating structure and the electromagnetic module to move simultaneously, so that the electromagnetic module can approach the adsorbed object (such as the running track of a slide) to achieve brake locking; the secondary floating structure is used to independently drive the electromagnetic module away from the adsorbed object, so that the electromagnetic module can separate from the adsorbed object to achieve brake unlocking. The two-stage floating structure provided on the electromagnetic brake device can control the extension and retraction travel of the electromagnetic module, so that when the electromagnetic module is away from the adsorbed object, the electromagnetic module can maintain a small distance between the electromagnetic module and the adsorbed object, which can reduce the noise generated by the electromagnetic module during the next adsorption, thereby improving the quietness of the brake. At the same time, the two-stage floating structure also helps to improve the smoothness and stability of the electromagnetic module's extension and retraction.

[0079] In some embodiments, the guide structure may also be installed on one of the two-stage floating structures, or the guide structure may also be installed on the two-stage floating structures respectively, both of which can effectively eliminate the jamming problem during the floating process.

[0080] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood.

This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0081] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0082] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0083] In one embodiment, an X-ray imaging device is provided. The X-ray imaging device may be a support device that supports a handpiece for emitting X-rays to a subject and also supports a flat-plate cassette for receiving X-rays that pass through the subject. Alternatively, the X-ray imaging device may be an X-ray emitting device comprising a handpiece and a support device, an X-ray receiving device comprising a flat-plate cassette and a support device, or an X-ray imaging system comprising a handpiece, a flat-plate cassette, and a support device.

[0084] Please refer to Figures 1 to 8 In this embodiment, the X-ray imaging equipment primarily comprises an electromagnetic brake device 1, a column 2, and a support device 3. The support device 3 comprises a pulley 31 and a ground rail 32. The pulley 31 straddles the ground rail 32 and can slide along the length of the ground rail 32. The column 2 is mounted on the pulley 31, and the column 2 and pulley 31 move together. The machine head or a flat film cassette can be mounted on the column 2. The electromagnetic brake device 1 is mounted on the pulley 31. When powered off, the electromagnetic brake device 1 can adhere to the ground rail 32, preventing the pulley 31 from moving relative to the ground rail 32, thus forming a locked brake. When powered on, the electromagnetic brake device 1 releases its grip on the ground rail 32, allowing the pulley 31 to move relative to the ground rail 32, thus forming an unlocked brake. The electromagnetic brake device 1 is normally locked and is unlocked only when the machine head or flat film cassette needs to move horizontally. Therefore, configuring the electromagnetic brake device 1 to be locked when powered off can further conserve energy. In other embodiments, the electromagnetic brake device 1 may also be configured to lock the brake in a powered-on state and unlock the brake in a powered-off state, thereby also realizing the brake locking and brake unlocking functions.

[0085] In this embodiment, a horizontal chute 321 is provided on the side or top of the ground rail 32. The pulley 31 is located at the upper end of the ground rail 32. Connecting portions 311 are provided on both sides or in the middle of the pulley 31. The connecting portions 311 extend into the chute 321 of the ground rail 32. Pulleys are mounted on the connecting portions 311, and the pulley 31 slides along the chute 321 via the pulleys. A column 2 is vertically mounted on the top surface of the pulley 31. The column 2 can be fixed relative to the pulley 31, or it can be rotatably mounted relative to the pulley 31, allowing the column 2 to rotate in the vertical direction. A lifting drive is mounted on the column 2, and the machine head or flat film box is connected to the lifting drive. The lifting drive is used to drive the machine head or flat film box to move vertically. The machine head or flat film box can also be fixedly mounted on the column 2.

[0086] The electromagnetic brake device 1 is installed on the connecting part 311 of the pulley 31. The electromagnetic brake device 1 can be installed on the outside of the connecting part 311. The connecting part 311 is provided with a hollow area. Part of the electromagnetic brake device 1 extends through the hollow area into the slide groove 321, so that the electromagnetic brake device 1 can electromagnetically adsorb the side of the slide groove 321 (the side can be any side in the slide groove 321).

[0087] In other embodiments, the electromagnetic brake device 1 may also be installed as a whole on the inner side of the connecting portion 311 , with part or the entire electromagnetic brake device 1 located in the slide groove 321 , and the electromagnetic brake device 1 may also achieve brake locking and brake unlocking.

[0088] In other embodiments, symmetrical slide grooves 321 are provided on both sides of the ground rail 32, and corresponding connecting parts 311 are provided on both sides of the pulley 31. An electromagnetic brake device 1 is installed on each connecting part 311. The two electromagnetic brake devices 1 perform brake locking and brake unlocking at the same time, which can improve the locking stability.

[0089] In other embodiments, the electromagnetic brake device 1 can also be installed in the chute 321, and the electromagnetic brake device 1 is fixedly connected to the ground rail 32. The electromagnetic brake device 1 is used to electromagnetically attract the connecting portion 311 of the pulley 31. In this state, multiple electromagnetic brake devices 1 need to be installed in the chute 321 of the ground rail 32. The spacing between adjacent electromagnetic brake devices 1 is less than the length of the pulley 31, so that the pulley 31 can be electromagnetically attracted and braked at any sliding position.

[0090] In this embodiment, the electromagnetic brake device 1 is a flat strip structure. The thickness of the electromagnetic brake device 1 perpendicular to the floating direction is much smaller than the length parallel to the floating direction. The electromagnetic brake device 1 is horizontally installed on the connecting part 311 of the pulley 31. The horizontal installation means that the thickness direction of the electromagnetic brake device 1 is along the vertical direction, and the floating direction of the electromagnetic brake device 1 is parallel to the horizontal direction. The horizontally installed electromagnetic brake device 1 eliminates the need to set a vertically higher slide groove 321 in the ground rail 32, which is beneficial to reducing the height of the ground rail 32.

[0091] In other embodiments, the electromagnetic brake device 1 may also be vertically mounted on the pulley 31 or the ground rail 32 , and brake locking and brake unlocking may also be achieved.

[0092] In this embodiment, the electromagnetic brake device 1 includes a first mounting seat 11 , a second mounting seat 12 , an electromagnetic module 13 , a first floating assembly 14 and a second floating assembly 15 .

[0093] The first mounting seat 11 and the second mounting seat 12 are both bar-shaped structures. The first mounting seat 11 can be set to be longer than the second mounting seat 12 so that both ends of the first mounting seat 11 protrude from the second mounting seat 12. The protruding ends of the first mounting seat 11 facilitate the installation of the first mounting seat 11.

[0094] The first mounting seat 11 is fixedly mounted to the connecting portion 311 of the pulley 31 by screw connection, welding, or other methods. The first mounting seat 11 has an N-shaped cross-section along its vertical length. The first mounting seat 11 includes a central mounting plate and side panels on either side. The mounting plate can be directly fixed to the connecting portion 311. The provision of the side panels can improve the structural strength of the first mounting seat 11, particularly ensuring the straightness and horizontality of the first mounting seat 11 along its length. The first mounting seat 11 can be an integrally formed structure, or it can be formed by welding the mounting plate and side panels.

[0095] In other embodiments, the first mounting base 11 may also include only a middle mounting plate, which can also achieve fixed connection and provide support.

[0096] In this embodiment, the second mounting seat 12 has an N-shaped cross-section along its vertical length, with the openings of the N-shaped structures of the first mounting seat 11 and the second mounting seat 12 facing each other. Each end of the second mounting seat 12 along its length is connected to the first mounting seat 11 via a first floating assembly 14, allowing the second mounting seat 12 to float relative to the first mounting seat 11 along a first direction, which is horizontal to the length of the vertical slot 321.

[0097] In other embodiments, the middle part of the second mounting seat 12 is floatingly connected to the first mounting seat 11 through the first floating component 14, and the two ends of the second mounting seat 12 are respectively slidingly connected to the second mounting seat 12 through guide structures such as guide rods, which can also enable the second mounting seat 12 to float relative to the first mounting seat 11.

[0098] In this embodiment, the N-shaped structure of the second mounting seat 12 forms a mounting groove 121, and the electromagnetic module 13 is installed in the mounting groove 121 of the second mounting seat 12. The two ends of the electromagnetic module 13 are respectively floatingly connected to the second mounting seat 12 through the second floating component 15. The electromagnetic module 13 can float relative to the second mounting seat 12 along a second direction, which is parallel to the first direction.

[0099] In other embodiments, the middle part of the electromagnetic module 13 is floatingly connected to the second mounting seat 12 through the second floating component 15, and the two ends of the electromagnetic module 13 are slidingly connected to the second mounting seat 12 through guiding structures such as guide rods, which can also enable the electromagnetic module 13 to float relative to the second mounting seat 12.

[0100] In this embodiment, the first floating assembly 14 is used to drive the second mounting seat 12, the electromagnetic module 13 located on the second mounting seat 12, and the second floating assembly 15 to float relative to the first mounting seat 11 in a first direction. The second floating assembly 15 is used to independently drive the electromagnetic module 13 to move relative to the second mounting seat 12 in a second direction. The first and second directions are parallel and opposite. The first floating assembly 14 consistently provides a driving force to drive the second mounting seat 12, the electromagnetic module 13 located on the second mounting seat 12, and the second floating assembly 15 away from the first mounting seat 11, while the second floating assembly 15 consistently provides a driving force to drive the electromagnetic module 13 toward the second mounting seat 12. In other words, the second floating assembly 15 consistently provides a driving force to drive the electromagnetic module 13 toward the first mounting seat 11.

[0101] The first floating assembly 14 includes a first guide rod 141, a guide cylinder 142, and a first elastic member 143. The first guide rod 141 has a first end and a second end. The first end of the first guide rod 141 is fixedly connected to the first mounting seat 11 by means of threaded connection, welding, or other means. The second mounting seat 12 has a through hole. The second end of the first guide rod 141 passes through the through hole of the second mounting seat 12 and extends into the mounting groove 121. A first retaining member 144, such as a screw or nut, is attached to the second end of the first guide rod 141. The outer diameter of the first retaining member 144 is larger than the inner diameter of the through hole of the second mounting seat 12 and the inner diameter of the guide cylinder 142. This ensures that the second end of the first guide rod 141 is retained within the mounting groove 121 and cannot escape from the through hole of the second mounting seat 12. The first guide rod 141 is fixedly connected to the first mounting seat 11 and slidably connected to the second mounting seat 12. The first guide rod 141 is perpendicular to the first mounting seat 11 and the second mounting seat 12, respectively. The first limiting portion 144 and the first guide rod 141 are detachably connected, so as to facilitate installation of the first floating assembly 14 between the first mounting seat 11 and the second mounting seat 12 .

[0102] The guide cylinder 142 is fixedly mounted on the second mounting seat 12. The guide cylinder 142 is located between the first mounting seat 11 and the second mounting seat 12. The guide cylinder 142 is vertically connected to the second mounting seat 12. The guide cylinder 142 is aligned with the through hole of the second mounting seat 12. The first guide rod 141 is disposed within the guide cylinder 142. The first guide rod 141 can move axially within the guide cylinder 142, and the guide cylinder 142 forms a sliding guide for the first guide rod 141. The guide cylinder 142 has a predetermined length. The length of the guide cylinder 142 is greater than or equal to the floating stroke of the second mounting seat 12 relative to the first mounting seat 11. The floating stroke is the movement stroke of the second mounting seat 12 relative to the first mounting seat 11 when the electromagnetic brake device 1 is in the brake locked and brake unlocked states. The guide cylinder 142 has a sufficient length so that the first guide rod 141 can obtain a longer support surface during the floating process, which can prevent the first guide rod 141 and the second mounting seat 12 from always remaining vertical, that is, ensuring that the second mounting seat 12 is parallel to the first mounting seat 11, avoiding the second mounting seat 12 from tilting, and thus avoiding the problem of jamming during the floating process.

[0103] In other embodiments, the first limiting portion 144 may be provided at the first end of the first guide rod 141, and the guide cylinder 142 may be fixedly mounted on the first mounting seat 11. In this structure, the first guide rod 141 is slidably connected to the first mounting seat 11, and the first guide rod 141 is fixedly connected to the second mounting seat 12. This structure may also achieve a floating connection between the first mounting seat 11 and the second mounting seat 12, and may also achieve the installation of the first floating assembly 14 between the first mounting seat 11 and the second mounting seat 12.

[0104] In this embodiment, the first elastic member 143 is a straight spring that is sleeved on the first guide rod 141 and further sleeved on the outside of the guide cylinder 142. The two ends of the first elastic member 143 are respectively abutted or fixedly connected to the first mounting seat 11 and the second mounting seat 12. The straight spring is always in a compressed state and serves as a power source, constantly providing elastic force to the second mounting seat 12 to drive the second mounting seat 12 away from the first mounting seat 11.

[0105] In other embodiments, the first elastic member 143 may also be a spring clip, and the first floating assembly 14 of the second mounting seat 12 may share a single spring clip. The spring clip has a bow-shaped structure, with the middle portion of the spring clip serving as a first connecting end and the ends of the spring clip serving as second connecting ends. The first connecting end of the spring clip abuts against the first mounting seat 11, while the second connecting ends of the spring clip abut against the second mounting seat 12. Alternatively, the first connecting end of the spring clip abuts against the second mounting seat 12, while the second connecting ends of the spring clip abut against the first mounting seat 11. The spring clip is always in a compressed state and can also provide the second mounting seat 12 with a constant elastic force that drives the second mounting seat 12 away from the first mounting seat 11.

[0106] In this embodiment, an elongated electromagnetic module 13 is mounted within the mounting slot 121 of the second mounting seat 12. The electromagnetic module 13 includes a middle region 131 and end regions 132. In the longitudinal direction, the middle region 131 has an end region 132 at each end. The end regions 132 are mounting ears that protrude from the middle region 131 and are used to position the electromagnetic module 13 within the mounting slot 121 of the second mounting seat 12. The middle region 131 includes a frame and an electromagnetic block embedded within the frame. The frame and the end regions 132 at both ends can be an integrated structure. The electromagnetic block is connected to an electrical wire 133. The middle portions of the first and second mounting seats 11, 12 each have a wire threading hole or threading opening. The electrical wire 133 passes through the wire threading hole or threading opening of the first and second mounting seats 11, 12 and is connected to the control circuit or control device.

[0107] The electromagnetic module 13 is a flat, long strip structure. The electromagnetic module 13 is thinner in the direction perpendicular to the floating direction (the width direction of the mounting groove 121) than the traditional electromagnet. The electromagnetic module 13 of this embodiment has a thinner thickness when installed horizontally, which is beneficial to reducing the thickness of the ground rail 32. At the same time, it can realize the miniaturization of the electromagnetic brake device 1 and reduce the space occupied by the electromagnetic brake device 1; and, the electromagnetic module 13 is longer in the direction parallel to the floating direction than the traditional electromagnet. The electromagnetic module 13 of this embodiment has sufficient volume to ensure that the electromagnetic module 13 has sufficient magnetic attraction to achieve stable brake locking.

[0108] In this embodiment, the second floating assembly 15 includes a second guide rod 151 and a second elastic member 152. The second guide rod 151 has a first end and a second end. The end region 132 is provided with a through-hole. The first end of the second guide rod 151 can be fixedly connected to the second mounting seat 12 by threading, welding, or other means. The second guide rod 151 is perpendicular to the second mounting seat 12. The second end of the second guide rod 151 passes through the through-hole in the end region 132. A second retaining member 153, such as a screw or nut, is mounted on the second end of the second guide rod 151. The outer diameter of the second retaining member 153 is larger than the inner diameter of the through-hole in the end region 132, thereby retaining the end region 132 on the second guide rod 151 and preventing it from dislodging from the second end of the second guide rod 151. The first end of the second guide rod 151 is fixedly connected to the second mounting seat 12, while the second end of the second guide rod 151 is slidably connected to the end region 132, allowing the electromagnetic module 13 to float relative to the second mounting seat 12.

[0109] The second elastic member 152 can be a straight spring, which is sleeved on the second guide rod 151. The two ends of the straight spring are respectively abutted or fixedly connected to the end area 132 and the second limiting portion 153. The straight spring is always in a compressed state, and the straight spring always provides elastic force to the electromagnetic module 13 close to the second mounting seat 12.

[0110] In other embodiments, the second guide rod 151 has a first end that can also be fixedly connected to the end area 132, and the second guide rod 151 has a second end that is slidably connected to the second mounting seat 12. The two ends of the second elastic member 152 are respectively abutted or fixedly connected to the second limiting portion 153 and the second mounting seat 12, and the electromagnetic module 13 can also float relative to the second mounting seat 12. At the same time, the second elastic member 152 can also always provide the electromagnetic module 13 with elastic force close to the second mounting seat 12.

[0111] In other embodiments, the second elastic member 152 may also be a spring, and the second limiting portion 153 extends along the length direction of the second mounting base 12 to form a strip-shaped structure. The spring is a bow-shaped structure, with the middle portion of the spring being the first connection end and the two ends of the spring being the second connection ends. The first connection end in the middle of the spring rests on the end region 132, and the second connection ends at both ends of the spring rest on the second limiting portion 153 respectively; or, the first connection end in the middle of the spring rests on the second limiting portion 153, and the second connection ends at both ends of the spring rest on the end regions 132 respectively. The spring is always in a compressed state, and can also always provide the electromagnetic module 13 with an elastic force close to the second mounting base 12.

[0112] In this embodiment, rollers 122 are provided at both ends of the second mounting seat 12 on a side away from the first mounting seat 11. The two rollers 122 are located in a straight line parallel to the second mounting seat 12. A running track 322 is provided within the chute 321 of the ground rail 32. The running track 322 is parallel to the length of the chute 321. The rollers 122 abut against the running track 322, and the electromagnetic brake device 1 is able to slide relative to the chute 321 via the rollers 122. The running track 322 can be formed from a structure such as a magnetically attracted metal plate, allowing the electromagnetic brake device 1 to achieve suction braking on the running track 322.

[0113] In other embodiments, a roller or a ball is installed in the slide groove 321 , and the electromagnetic brake device 1 can also slide relative to the slide groove 321 .

[0114] In this embodiment, the working principle of the electromagnetic brake device 1 is as follows:

[0115] Under the elastic force of the first elastic member 143, the first elastic member 143 pushes the second mounting base 12, the electromagnetic module 13 thereon, and the second floating assembly 15 toward the running track 322. The elastic force of the first elastic member 143 is always greater than the elastic force of the second elastic member 152, so that the roller 122 always maintains contact with the running track 322. Because the first elastic member 143 constantly provides thrust to the roller 122, the roller 122 can achieve floating travel on the uneven running track 322.

[0116] Please refer to Figure 7 In the power-off state, the electromagnetic module 13 has a magnetic attraction force, which is greater than the elastic force of the second elastic member 152. The magnetic attraction force overcomes the elastic force of the second elastic member 152 and drives the electromagnetic module 13 to move to contact the walking rail 322, forming a brake lock; in this state, the electromagnetic brake device 1 cannot slide relative to the ground rail 32, thereby locking the horizontal movement of the head or flat film box. In this state, the head or flat film box can stably perform video recording.

[0117] Please refer to Figure 8 When powered on, the electromagnetic module 13 loses its magnetic attraction. Under the elastic force of the second elastic member 152, the second elastic member 152 pushes the electromagnetic module 13 away from the running track 322 and separates from the running track 322, thereby unlocking the brake. In this state, the electromagnetic brake device 1 can slide relative to the ground rail 32, and the machine head or flat film box can move horizontally. Because the roller 122 is always in contact with the running track 322 under the elastic force of the first elastic member 143, the distance between the electromagnetic module 13 and the running track 322 is not too large. When the power is turned off again, the electromagnetic module 13 can be attracted to the running track 322 after a short movement, which can reduce the noise generated by the attraction.

[0118] In this embodiment, the electromagnetic brake device 1 is provided with a two-stage floating structure, which can control the stroke of magnetic floating, which is beneficial to reducing the noise generated by magnetic attraction. The two-stage floating structure is also beneficial to improving the smoothness and stability of floating; and, the electromagnetic brake device 1 is also provided with a guide structure, which extends the support surface in the floating direction, so that even if the electromagnetic brake device 1 is installed horizontally, it will not get stuck during the floating process.

[0119] Please refer to Figure 9 In one embodiment, a socket 123 is further provided on the side of the second mounting seat 12. The socket 123 is located at the end of the second mounting seat 12 near the first mounting seat 11 and communicates with the bottom of the mounting groove 121. The socket 123 is used to insert a gasket 124 into the mounting groove 121. The gasket 124 is located between the second mounting seat 12 and the electromagnetic module 13. The gasket 124 can be fixedly connected to the second mounting seat 12 by means of screws or other means. The gasket 124 is used to limit the retraction travel limit of the electromagnetic module 13.

[0120] The gasket 124 is used to eliminate machining and installation errors in the electromagnetic module 13, ensuring a predetermined gap between the electromagnetic module 13 and the running track 322 when powered on. This gap can be between 0.1 mm and 0.5 mm, with an optimal value of 0.2 mm. This small gap between the electromagnetic module 13 and the running track 322 reduces the magnetic attraction sound to a near-inaudible level, providing a better user experience.

[0121] The provision of the socket 123 allows for the installation of the electromagnetic brake device 1 by first installing the electromagnetic module 13 on the second mounting base 12, and then, after commissioning, installing the gasket 124 of a specific thickness through the socket 123 between the second mounting base 12 and the electromagnetic module 13. The installation of the gasket 124 not only eliminates the need to remove the commissioned electromagnetic module 13 from the second mounting base 12, but also avoids installation errors caused by reinstalling the electromagnetic module 13.

[0122] In one embodiment, the electromagnetic brake device 1 may include a first mounting seat 11 , a second mounting seat 12 , an electromagnetic module 13 and a first floating assembly 14 , but the electromagnetic brake device 1 does not include a second floating assembly 15 .

[0123] The electromagnetic module 13 is fixedly mounted on the second mounting seat 12 , and the first floating assembly 14 always provides the second mounting seat 12 with an elastic force to drive the second mounting seat 12 and the electromagnetic module 13 away from the walking track 322 , and the electromagnetic force of the electromagnetic module 13 in the power-off state is greater than the elastic force of the first floating assembly 14 .

[0124] In the power-off state, the electromagnetic module 13 has a magnetic attraction force, which drives the electromagnetic module 13 to overcome the elastic force of the first floating component 14 and move to contact the walking track 322, forming a brake lock;

[0125] In the power-on state, the electromagnetic module 13 loses its magnetic attraction, and the elastic force of the first floating assembly 14 drives the electromagnetic module 13 to separate from the travel track 322 , thereby releasing the brake.

[0126] The electromagnetic brake device 1 can also achieve brake locking and brake unlocking without including the second floating assembly 15 .

[0127] In one embodiment, an X-ray imaging device includes an electromagnetic brake device 1 and a column 2. A lifting drive device is mounted on the column 2. The lifting drive device includes a pulley. A vertical slide is provided on the column 2. The pulley can be vertically lifted and lowered along the pulley. A head or a flat film cassette can be mounted on the pulley. The lifting drive device drives the head or flat film cassette to lift and lower via the pulley. The electromagnetic brake device 1 is the electromagnetic brake device 1 in any of the above embodiments.

[0128] The electromagnetic brake device 1 can be installed on the pulley, and the electromagnetic brake device 1 is located in the chute. The electromagnetic brake device 1 can lock and unlock the brake of the pulley by adsorbing the column 2. The electromagnetic brake device 1 can also be installed in the chute of the column 2. The electromagnetic brake device 1 can also lock and unlock the brake of the pulley by adsorbing the pulley.

[0129] The electromagnetic brake device 1 can limit the lifting and movement of the flat film box relative to the column 2, or the electromagnetic brake device 1 can limit the lifting and movement of the head relative to the column 2. This prevents the head or flat film box from shaking when not in use or when it is raised to a specified height for shooting, thereby improving safety and shooting stability.

[0130] In one embodiment, an X-ray imaging device includes an electromagnetic brake device 1, a column 2, and a support device 3. The electromagnetic brake device 1 is mounted on the support device 3 to limit the horizontal movement of the column 2. The electromagnetic brake device 1 is also mounted on the column 2 to limit the vertical movement of the head or flat film cassette relative to the column 2. This allows the head or flat film cassette to lock and unlock the brake in both horizontal and vertical degrees of freedom, improving safety and imaging stability. The electromagnetic brake device 1 is any of the aforementioned embodiments.

[0131] In one embodiment, an electromagnetic brake device is provided. The electromagnetic brake device is the electromagnetic brake device 1 in any of the above embodiments. The electromagnetic brake device is applied to X-ray imaging equipment to lock and limit the horizontal movement of the machine head or the flat film box, or to lock and limit the lifting movement of the machine head or the flat film box; the electromagnetic brake device can also be applied to other medical equipment.

[0132] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
