Curtain device and image device

Abstract

This application provides a curtain device and imaging equipment. The device comprises a rewinding mechanism at each end of an arc-shaped guide mechanism, with the free ends of two curtain bodies fixedly connected to the same drive mechanism, and the fixed end of each curtain body connected to a rewinding mechanism. Thus, as the drive mechanism moves the X-ray source component along an arc-shaped trajectory, it simultaneously unfolds one curtain body while rewinding the other, ensuring that at least one curtain body can shield the arc-shaped travel cavity. This configuration allows both curtain bodies to shield the arc-shaped travel cavity when the drive mechanism moves the X-ray source component to any shooting position, preventing accidental insertion of hands into the cavity and reducing the risk of dust, debris, and other foreign objects entering. This enhances the safety of the imaging equipment and improves its aesthetic appearance.

[0006] In some embodiments, the drive mechanism includes: A motion component, connected to the free end and movably connected to the arc-shaped guide rail, drives the free end to move along the extension direction of the arc-shaped guide rail; and A driving component is disposed on the motion component and is connected to the motion component in a transmission manner to drive the motion component to move along the extension direction of the arc-shaped guide rail.

[0007] In some embodiments, the arc-shaped guide rail is provided with toothed grooves arranged along its own extension direction; The motion component includes: A connector, wherein the driving component is fixed to the connector; A moving component, connected to the connecting component and movably connected to the arc-shaped guide rail, the moving component being connected to the free end; and The gear is connected to the connector and fixedly connected to the output end of the drive member. The gear meshes with the tooth groove. Under the drive of the drive member, the gear drives the moving member to move along the extension direction of the arc-shaped guide rail.

[0008] In some embodiments, the arc-shaped guide rail is provided with a guide groove arranged along its own extension direction, the groove wall of the guide groove is formed with the tooth groove, and the gear portion is located in the guide groove to mesh with the tooth groove; The moving part is embedded in the guide groove and is slidably or rollingly connected to the groove wall.

[0009] In some embodiments, the curtain device further includes: A stop is provided at both opposite ends of the arc-shaped guide rail along its length direction, and is used to abut against the moving component to prevent the moving component from disengaging from the arc-shaped guide rail.

[0010] In some embodiments, the winding mechanism includes: A fixing frame, the two ends of which are respectively connected to the arc-shaped guide rail and the support assembly; A roller is rotatably mounted on the fixing frame, the fixing end is fixed to the roller, and at least a portion of the curtain body is wound around the roller; and A coil spring, the inner end of which is connected to the coil shaft, and the outer end of which is connected to the fixed frame, the coil spring being wound up or released as the coil shaft rotates.

[0011] In some of these embodiments, it also includes: Multiple reinforcing members are provided, which extend along the width direction of the curtain body and are connected to the curtain body. The multiple reinforcing members are spaced apart along the length direction of the curtain body.

[0012] In some embodiments, the spacing between two adjacent reinforcing members is equal; and / or Each of the reinforcing members has a protective element on the side facing away from the curtain body; and / or The extension length of the reinforcing member is equal to the width of the curtain body.

[0014] Based on the above structural configuration, this embodiment of the application sets a winding mechanism at each end of the arc-shaped guide mechanism, and fixes the free ends of the two curtain bodies to the same drive mechanism, with each curtain body's fixed end connected to a winding mechanism. Thus, as the drive mechanism moves the X-ray source component along the arc-shaped trajectory, it can simultaneously unfold one curtain body while rewinding the other, ensuring that at least one curtain body can shield the arc-shaped travel cavity. This configuration allows both curtain bodies to shield the arc-shaped travel cavity when the drive mechanism moves the X-ray source component to any shooting position, preventing accidental insertion of a hand into the cavity and reducing the risk of dust, debris, and other foreign objects entering. This enhances the safety of the imaging equipment and improves its aesthetic appearance. Furthermore, this embodiment of the application provides a winding mechanism at the fixed end of the curtain body and a driving mechanism at the free end. Through the cooperation of the driving mechanism and the winding mechanism, the automatic unfolding and retraction of the curtain body is achieved, improving the automation level of the curtain body during movement. Simultaneously, this arrangement ensures that both the fixed and free ends of the curtain body bear force during unfolding or retraction, thereby maintaining tension throughout the process and effectively preventing the problem of collapse in the middle of the curtain body due to unilateral force. It also ensures that the curtain body remains flat during unfolding or retraction, avoiding wrinkles or jamming, allowing the curtain body to unfold or retract smoothly and steadily, thus contributing to improved reliability and stability of the curtain device.

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] Please see Figure 1 and Figure 2This application provides an imaging device 1000, which is a medical device used to capture images of the internal structure of the human body and generate medical images. The imaging device 1000 includes, but is not limited to, chest X-ray machines, CT scanners, and X-ray machines. In this application embodiment, a mammography machine is used as an example for illustration.

[0020] The imaging device 1000 includes a radiation source component 200, which, as the core component of the imaging device 1000, is used to emit X-rays or other forms of radiation to penetrate human tissue and generate images. It is understood that the imaging device 1000 has an arc-shaped travel cavity 10a for accommodating the movement of a drive mechanism 40. To achieve imaging at different angles, the drive mechanism 40 moves along an arc-shaped trajectory within the arc-shaped travel cavity 10a to move the radiation source component 200 to different imaging positions.

[0021] However, in the relevant technology, the arc-shaped travel cavity 10a is open, which not only makes it easy for people to accidentally put their hands in and cause safety accidents, but also makes it easy for foreign objects such as dust and debris to enter, affecting the normal use of the imaging equipment 1000.

[0022] To address the aforementioned issues, this application also provides a curtain device 100, which is applied to an imaging device 1000 and includes an arc-shaped guide mechanism 10, a winding mechanism 20, a curtain body 30, and a drive mechanism 40.

[0023] The arc-shaped guide mechanism 10 provides a stable and reliable path support for the movement of the X-ray source component 200 in the imaging equipment 1000, enabling the X-ray source component 200 to remain stable during movement. The arc-shaped guide mechanism 10 has an arc-shaped travel cavity 10a extending along its own arc-shaped trajectory, and an opening 10b extending along the arc-shaped trajectory and communicating with the arc-shaped travel cavity 10a, that is, the arc-shaped travel cavity 10a is open. The arc-shaped travel cavity 10a is used to accommodate the drive mechanism 40, that is, the drive mechanism 40 is disposed in the arc-shaped travel cavity 10a and can move along the extension direction of the arc-shaped travel cavity 10a to drive the X-ray source component 200 to move along the arc-shaped trajectory, realizing multi-angle imaging.

[0024] There are two winding mechanisms 20, which are respectively located at opposite ends of the arc-shaped guide mechanism 10 in its extension direction. There are also two curtain bodies 30, each with a fixed end 31 and a free end 32 arranged opposite to each other. Specifically, the fixed end 31 of each curtain body 30 is fixedly connected to one winding mechanism 20, and at least a portion of the curtain body 30 is wound around the winding mechanism 20; the free ends 32 of both curtain bodies 30 extend towards each other along the extension direction of the arc-shaped travel cavity 10a, that is, the free end 32 of one curtain body 30 extends towards the other curtain body 30 along the extension direction of the arc-shaped travel cavity 10a. Understandably, the winding mechanism 20 winds and collects the curtain bodies 30 sequentially from the fixed end 31 to the free end 32. The curtain bodies 30 are typically made of a material with good flexibility, such as non-woven fabric, polyester, or polyester fiber, to facilitate smooth unfolding or retraction and to improve durability.

[0025] The drive mechanism 40 serves as the power source for the imaging device 1000. It is movably connected to the arc-shaped guide mechanism 10 and located within the arc-shaped travel cavity 10a. The drive mechanism 40 can reciprocate along the extension direction of the arc-shaped travel cavity 10a. The X-ray source component 200 is connected to the drive mechanism 40, allowing it to move along the extension direction of the arc-shaped guide mechanism 10 under the drive of the drive mechanism 40, thus enabling the X-ray source component 200 to move at different shooting positions. Furthermore, the drive mechanism 40 is fixedly connected to the free ends 32 of the two curtain bodies 30, meaning the free ends 32 of the two curtain bodies 30 are fixedly connected to the same drive mechanism 40. In this embodiment, the free ends 32 of the two curtain bodies 30 are mounted on the drive mechanism 40 used to drive the movement of the X-ray source component 200; thus, the free ends 32 and the X-ray source component 200 share the same drive mechanism 40. With this configuration, the X-ray source component 200 and the free end 32 of the curtain body 30 can move synchronously under the drive of the drive mechanism 40, ensuring the coordination of the movement of the X-ray source component 200 and the free end 32. This further ensures that no matter what shooting position the drive mechanism 40 moves the X-ray source component 200 to, the curtain body 30 can block the opening 10b of the arc-shaped travel cavity 10a, thus improving safety.

[0026] During the process of the drive mechanism 40 driving the X-ray source component 200 to move along the extension direction of the arc-shaped travel cavity 10a, the drive mechanism 40 can simultaneously drive one of the curtain bodies 30 to release at least a portion, and the other curtain body 30 to roll back at least a portion, so that the opening 10b is blocked by at least one curtain body 30 during the movement of the drive mechanism 40 along the arc-shaped travel cavity 10a. Specifically, when the drive mechanism 40 drives the free end 32 of one of the curtain bodies 30 to move away from the corresponding winding mechanism 20, the drive mechanism 40 applies a traction force to the free end 32 of the curtain body 30 in a direction away from the winding mechanism 20. Under the action of the traction force, the winding mechanism 20 rotates and releases at least a portion of the curtain body 30 wound around itself, so that the curtain body 30 unfolds smoothly along the preset path. At the same time, during this process, the drive mechanism 40 drives the free end 32 of the other curtain body 30 to move closer to the corresponding winding mechanism 20. At this time, under the action of the winding force of the winding mechanism 20, the winding mechanism 20 rotates in the opposite direction and winds back at least a portion of the curtain body 30 to itself, so as to wind and store the curtain body 30.

[0027] Furthermore, with Figure 1 and Figure 2 Taking the direction shown as an example, when the drive mechanism 40 drives the X-ray source component 200 to move to the left along the extension direction of the arc-shaped travel cavity 10a, the free end 32 of the curtain body 30 located on the left side of the drive mechanism 40 moves towards the left-side winding mechanism 20 under the drive of the drive mechanism 40. The left-side winding mechanism 20 winds up part of the left-side curtain body 30, so that the left-side curtain body 30 can be closed, shortening the unfolded size of the left-side curtain body 30. At the same time, the free end 32 of the curtain body 30 located on the right side of the drive component 42 moves away from the right-side winding mechanism 20 under the drive of the drive mechanism 40. The right-side winding mechanism 20 releases part of the right-side curtain body 30 that has been wound up, so that the right-side curtain body 30 can be unfolded, increasing the unfolded size of the right-side curtain body 30. It should be noted that when the drive mechanism 40 drives the X-ray source component 200 to move to the right along the extension direction of the arc-shaped travel cavity 10a, the movement modes of the two curtain bodies 30 are opposite.

[0028] Furthermore, when the drive mechanism 40 drives the X-ray source component 200 to move to the leftmost position along the extension direction of the arc-shaped travel cavity 10a, the curtain body 30 located on the left side of the drive mechanism 40 is completely wound around the left winding mechanism 20, that is, the left curtain body 30 is completely closed; at the same time, the curtain body 30 located on the right side of the drive component 42 completely releases the portion wound around the right winding mechanism 20, so that the right curtain body 30 is fully unfolded. At this time, the right curtain body 30 covers the opening 10b of the arc-shaped travel cavity 10a. It should be noted that when the drive mechanism 40 drives the X-ray source component 200 to move to the rightmost position along the extension direction of the arc-shaped travel cavity 10a, the states of the two curtain bodies 30 are opposite, and the left curtain body 30 covers the opening 10b of the arc-shaped travel cavity 10a.

[0029] It should be understood that when the drive mechanism 40 drives the curtain body 30 to unfold, the winding mechanism 20 can simultaneously release the curtain body 30, allowing the curtain body 30 to unfold smoothly. During the unfolding of the curtain body 30, the free end 32 of the curtain body 30 is subjected to traction force, while the fixed end 31 is constrained by the winding mechanism 20. This method of force at both ends ensures that the curtain body 30 remains taut during the unfolding process, effectively preventing the problem of collapse in the middle area. At the same time, the drive mechanism 40 pulls the free end 32 and drives the winding mechanism 20 to rotate, releasing the wound part of the curtain body 30. This avoids the problem of damage to the curtain body 30 caused by excessive pulling by the drive mechanism 40. When the drive mechanism 40 pulls the curtain body 30 together, the drive mechanism 40 moves the free end 32 toward the corresponding winding mechanism 20. Under the action of the rewinding force, the winding mechanism 20 can quickly and orderly rewind the curtain body 30 to neatly store the curtain body 30. During the process of pulling the curtain body 30 together, the fixed end 31 of the curtain body 30 is subjected to the rewinding force, while the free end 32 is constrained by the drive mechanism 40. This method of being subjected to force at both ends ensures that the curtain body 30 remains taut during the pulling process, avoiding the problem of the curtain body 30 collapsing in the middle. At the same time, the winding mechanism 20 rewinds the taut curtain body 30 to avoid the problem of jamming during winding or wrinkles in the curtain body 30 after winding.

[0030] Furthermore, with Figure 1 and Figure 2Taking the direction shown as an example, when the drive mechanism 40 drives the X-ray source component 200 to move to the left along the extension direction of the arc-shaped stroke cavity 10a, the curtain body 30 located on the left side of the drive mechanism 40 performs a closing operation. During the closing process, the free end 32 of the left curtain body 30 is driven by the drive mechanism 40, and the fixed end 31 is subjected to the rewinding force of the left winding mechanism 20, so that the left curtain body 30 always remains taut when closing, avoiding the problem of the curtain body 30 collapsing in the middle during the closing operation. At the same time, the curtain body 30 located on the right side of the drive component 42 performs an unfolding operation. During the unfolding process, the free end 32 of the right curtain body 30 is driven by the drive mechanism 40 and pulls the curtain body 30 to be released from the right winding mechanism 20, so that the right curtain body 30 always remains taut when unfolding, avoiding the problem of the curtain body 30 collapsing in the middle during the unfolding operation. It should be noted that when the drive mechanism 40 drives the X-ray source component 200 to move to the right along the extension direction of the arc-shaped stroke cavity 10a, the operation mode of the two curtain bodies 30 is opposite.

[0031] It should also be noted that in some embodiments, the drive mechanism 40 drives the X-ray source component 200 to the imaging position located in the middle of the arc-shaped guide mechanism 10. At this time, neither of the curtain bodies 30 on both sides is fully unfolded; that is, only a portion of the curtain bodies 30 is unfolded, while the other portion remains wound around the winding mechanism 20. In this example, the two curtain bodies 30 together cover the opening 10b of the arc-shaped travel cavity 10a. Furthermore, the free end 32 of the curtain body 30 is subjected to the traction force of the drive mechanism 40, while the fixed end 31 is subjected to the rewinding force of the winding mechanism 20. In other words, both ends of the curtain body 30 are subjected to force, and the forces at both ends are balanced. This allows the curtain body 30 to be stably maintained at the unfolded length, and the curtain body 30 can always be kept taut, avoiding the problem of the middle of the curtain body 30 collapsing. Specifically, the free end 32 of the left curtain body 30 is subjected to the traction force of the drive mechanism 40, and the fixed end 31 is subjected to the rewinding force of the left winding mechanism 20; and the free end 32 of the right curtain body 30 is subjected to the traction force of the drive mechanism 40, and the fixed end 31 is subjected to the rewinding force of the right winding mechanism 20. In this way, both curtain bodies 30 are in a taut state, avoiding the problem of the middle of the curtain body 30 collapsing.

[0032] Based on the above structural configuration, this embodiment of the application provides a winding mechanism 20 at each end of the arc-shaped guide mechanism 10, and fixes the free ends 32 of the two curtain bodies 30 to the same drive mechanism 40. The fixed end 31 of each curtain body 30 is connected to a winding mechanism 20. Thus, during the motion of the X-ray source component 200 along the arc-shaped trajectory driven by the drive mechanism 40, one curtain body 30 can be simultaneously unfolded while the other curtain body 30 is rolled back, allowing at least one curtain body 30 to shield the arc-shaped travel cavity 10a. With this configuration, when the drive mechanism 40 moves the X-ray source component 200 to any shooting position, both curtain bodies 30 can shield the arc-shaped travel cavity 10a, preventing accidental insertion of a hand into the arc-shaped travel cavity 10a and reducing the risk of dust, debris, and other foreign objects entering. This improves the safety of the imaging equipment 1000 and also enhances the aesthetics of the equipment. Furthermore, in this embodiment, a winding mechanism 20 is provided at the fixed end 31 of the curtain body 30, and a driving mechanism 40 is provided at the free end 32. Through the cooperation of the driving mechanism 40 and the winding mechanism 20, the automatic unfolding and retraction of the curtain body 30 is realized, improving the automation level of the curtain body 30 during movement. At the same time, this arrangement also ensures that both the fixed end 31 and the free end 32 of the curtain body 30 bear force during unfolding or retraction, thereby keeping the curtain body 30 taut at all times during unfolding or retraction, effectively avoiding the problem of collapse in the middle of the curtain body 30 due to unilateral force; it also ensures that the curtain body 30 remains flat during unfolding or retraction, avoiding wrinkles or jamming, enabling the curtain body 30 to unfold or retract smoothly and steadily, which helps to improve the reliability and stability of the curtain device 100.

[0033] Please see Figure 2 In some embodiments, the arc-shaped guide mechanism 10 includes an arc-shaped guide rail 11 and a support assembly 12.

[0034] The drive mechanism 40 is movably connected to the arc-shaped guide rail 11 to move along the extension direction of the arc-shaped guide rail 11. The arc-shaped guide rail 11 provides a stable and reliable path support for the movement of the drive mechanism 40, making the drive mechanism 40 move more smoothly and steadily, and reducing the occurrence of shaking and jamming of the curtain body 30 and the radiation source component 200.

[0035] The support component 12 extends in the same direction as the arc-shaped guide rail 11, i.e., both extend along an arc-shaped trajectory. The support component 12 and the arc-shaped guide rail 11 are spaced apart and together define an arc-shaped travel cavity 10a, i.e., the arc-shaped travel cavity 10a is formed between the support component 12 and the arc-shaped guide rail 11. The winding mechanism 20 is disposed between the arc-shaped guide rail 11 and the support component 12, and both ends of the winding mechanism 20 are connected to the arc-shaped guide rail 11 and the support component 12, respectively. In this way, support is provided for the winding mechanism 20, avoiding the problem of the curtain body 30 failing due to the winding mechanism 20 sagging.

[0036] Please refer to the following: Figure 5 and Figure 6 In some embodiments, the drive mechanism 40 includes a motion component 41 and a drive member 42. The motion component 41 is connected to the free end 32 and movably connected to the arc-shaped guide rail 11 to drive the free end 32 to move along the extension direction of the arc-shaped guide rail 11. The drive member 42 is fixedly mounted on the motion component 41 and is drively connected to the motion component 41. The drive member 42 provides power support to the motion component 41, driving the motion component 41 to move along the extension direction of the arc-shaped guide rail 11. With this configuration, through the cooperation of the drive member 42 and the motion member 412, the X-ray source component 200 can be precisely driven to move, and the two curtain bodies 30 can be driven to open or close simultaneously, so that the two curtain bodies 30 can always cover the opening 10b of the arc-shaped travel cavity 10a, improving the automation level of the curtain bodies 30 during the movement process, thereby improving the ease of use and operating efficiency of the curtain device 100.

[0037] It should be noted that the type of the driving component 42 is not specifically limited in this application embodiment. The driving component 42 can be a drive motor, a cylinder, etc. When the driving component 42 is a drive motor, the movement direction of the motion component 41 can be changed by changing the forward and reverse rotation of the drive motor, thereby adjusting the unfolding or retracting state of the curtain body 30. The drive motor includes, but is not limited to, a stepper motor, a DC motor, etc.

[0038] The output end of the drive component 42 can be directly connected to the motion component 41, thereby directly driving the motion component 41 to move along the arc-shaped guide rail 11. Alternatively, a transmission structure can be provided, which is connected to both the output end of the drive component 42 and the motion component 41, thereby indirectly driving the motion component 41 to move along the arc-shaped guide rail 11. The transmission structure can be a linkage structure, etc., and this embodiment does not impose specific limitations on it.

[0039] Please see Figure 5 and Figure 6In an exemplary embodiment, the arc-shaped guide rail 11 is provided with toothed grooves 112 arranged along its own extension direction; the motion component 41 includes a connector 411, a moving component 412, and a gear 413. Specifically, the drive component 42 is fixed to the connector 411; the moving component 412 is connected to the connector 411 and movably connected to the arc-shaped guide rail 11, and the moving component 412 is connected to the free end 32; the gear 413 is connected to the connector 411 and fixedly connected to the output end of the drive component 42, the gear 413 meshes with the toothed grooves 112, and under the drive of the drive component 42, the gear 413 drives the moving component 412 to move along the extension direction of the arc-shaped guide rail 11. This configuration integrates the moving component 412, gear 413, and drive component 42 via the connector 411, improving the integration level of the drive mechanism 40. Furthermore, the transmission method between the gear 413 and the tooth groove 112 has high transmission accuracy and stability, ensuring that the moving component 41 moves smoothly along the extension direction of the arc-shaped guide rail 11, thus enhancing the stability of the movement of the moving component 41.

[0040] In some embodiments, the arc-shaped guide rail 11 is provided with a guide groove 111 extending along its own direction. The groove wall of the guide groove 111 forms a toothed groove 112. In this case, the gear 413 is partially located within the guide groove 111 to mesh with the toothed groove 112. With this configuration, at least two sides of the gear 413 are constrained by the groove wall of the guide groove 111, reducing the problem of gear 413 deviating during movement and improving the smoothness of the movement of the gear 413 relative to the toothed groove 112. The toothed groove 112 can be provided within the guide groove 111, for example, the toothed groove 112 is provided on the bottom groove wall of the guide groove 111. In addition, the toothed groove 112 being provided on the bottom groove wall of the guide groove 111 means that it is located opposite to the opening of the guide groove 111. This can prevent other components in the moving assembly 41 from contacting the toothed groove 112 and affecting the meshing of the gear 413 with the toothed groove 112, thus reducing the impact on the movement process of the moving assembly 41.

[0041] It should be noted that the embodiments of this application do not impose specific limitations on the formation method of the toothed grooves 112 on the groove wall of the guide groove 111. For example, grooves can be opened on the groove wall of the guide groove 111 to form toothed grooves 112; for another example, multiple connecting posts can be provided on the groove wall of the guide groove 111 at intervals along its own extension direction, with toothed grooves 112 formed between each two adjacent connecting posts; for yet another example, a chain can be provided on the groove wall of the guide groove 111 extending along its own extension direction, and the chain is provided with toothed grooves 112.

[0042] Furthermore, a portion of the moving part 412 is embedded within the guide groove 111 and rolls against the groove wall. The guide groove 111 provides stable path support for the moving part 412; understandably, the portion of the moving part 412 within the guide groove 111 rolls against the groove wall, while the portion outside the guide groove 111 connects to the free end 32 to drive the free end 32. Alternatively, in other examples, the moving part 412 slides against the groove wall of the guide groove 111. Moreover, it should be noted that the rolling connection between the moving part 412 and the guide groove 111, compared to a sliding connection, reduces the frictional resistance between the moving part 412 and the guide groove 111, reduces wear, and extends the service life of both the moving part 412 and the arc-shaped guide rail 11.

[0043] Optionally, the walls of the guide groove 111 are polished to improve its smoothness, reduce the frictional resistance between the moving part 412 and the guide groove 111, making the moving part 412 move more smoothly along the guide groove 111, thereby making the opening and closing of the curtain body 30 smoother. The walls of the guide groove 111 can be polished using a POM (polyoxymethylene) polishing process.

[0044] Please see Figure 3 and Figure 4 In some embodiments, each winding mechanism 20 includes a fixing frame 21, a winding shaft 22, and a coil spring 23.

[0045] Specifically, the two ends of the fixing frame 21 are respectively connected to the arc-shaped guide rail 11 and the support component 12. The fixing frame 21 can be connected to the arc-shaped guide rail 11 and the support component 12 by means of screws, welding, etc., so as to stably fix the fixing frame 21 on the arc-shaped guide mechanism 10, improve the connection stability, prevent the winding mechanism 20 from sagging, and prevent the winding mechanism 20 from shifting due to vibration during operation, thus ensuring the stable operation and reliability of the curtain device 100.

[0046] The roller 22 is rotatably mounted on the fixed frame 21, and the fixed end 31 is fixed to the roller 22. At least a portion of the curtain body 30 is wound around the roller 22. Optionally, the roller 22 can be rotatably connected to the fixed frame 21 via bearings to reduce the friction between the roller 22 and the fixed frame 21 during rotation, making the roller 22 rotate more smoothly and ensuring smoother winding and unwinding of the curtain body 30. Understandably, the curtain body 30 has a certain length in the height direction to cover a certain space. The roller 22 is connected to the fixed end 31 along the height direction to ensure that the curtain body 30 can be neatly wound around the roller 22 along the height direction, avoiding wrinkles in the curtain body 30. In this embodiment, the connection method between the roller 22 and the fixed end 31 is not specifically limited. The roller 22 and the fixed end 31 can be connected by means of adhesive bonding, which not only fixes the fixed end 31 to the roller 22 but also does not damage the curtain body 30, improving the safety and reliability of the curtain body 30.

[0047] The coil spring 23 has an inner end and an outer end. The inner end of the coil spring 23 is connected to the roller 22, and the outer end is connected to the fixing frame 21. When the coil spring 23 is wound up or released with the rotation of the roller 22, the elastic restoring force it generates drives the roller 22 to rotate in the opposite direction, thereby rewinding the curtain body 30. Specifically, during the unfolding of the curtain body 30, the coil spring 23 is wound up accordingly (i.e., the coil spring 23 is compressed) as the roller 22 rotates; while during the closing of the curtain body 30, the free end 32 is no longer subjected to traction force. At this time, the coil spring 23 can return to its natural state (i.e., the coil spring 23 is released) and generate an elastic restoring force to drive the roller 22 to rotate in the opposite direction, thereby realizing the automatic rewinding of the curtain body 30. The elastic restoring force is the rewinding force of the winding mechanism 20. With this configuration, the coil spring 23 provides a stable and reliable rewinding force for the winding mechanism 20, enabling the curtain body 30 to rewind automatically and orderly, further improving the automation level and ease of use of the curtain device 100; at the same time, the method of using the coil spring 23 to realize the rotation of the roller 22 is simple in structure and easy to assemble.

[0048] Specifically, when the moving component 412 drives the free end 32 to move away from the winding mechanism 20, the moving component 412 applies a traction force to the free end 32 in a direction opposite to the winding mechanism 20. Under the action of the traction force, the roller 22 rotates in the forward direction and releases at least a portion of the curtain body 30 wound around itself, so that the curtain body 30 can be unfolded smoothly. During this process, the coil spring 23 is wound up (the coil spring 23 is compressed) so that the coil spring 23 stores elastic potential energy. When the moving component 412 drives the free end 32 to move closer to the winding mechanism 20, the moving component 412 no longer applies a traction force to the free end 32. At this time, the coil spring 23 releases its elastic potential energy, generates an elastic restoring force, and drives the roller 22 to rotate in the opposite direction and rewind at least a portion of the curtain body 30 around itself, so as to wind and store the curtain body 30.

[0049] Furthermore, with Figure 1 and Figure 2 Taking the direction shown as an example, when the drive mechanism 40 drives the radiation source component 200 to move to the left along the extension direction of the arc-shaped stroke cavity 10a, the free end 32 of the curtain body 30 located on the left side of the drive mechanism 40 moves towards the left-side winding mechanism 20 under the drive of the moving component 412. At this time, the coil spring 23 in the left-side winding mechanism 20 releases elastic potential energy, generates elastic restoring force, and drives the left-side roller 22 to rotate in the opposite direction and rewind at least part of the left-side curtain body 30 to itself, so as to wind and store the curtain body 30. At the same time, the free end 32 of the curtain body 30 located on the right side of the drive component 42 moves away from the right-side winding mechanism 20 under the drive of the drive mechanism 40. At this time, the right-side winding mechanism 20 releases part of the right-side curtain body 30 that is wound around itself, and the coil spring 23 in the right-side winding mechanism 20 is compressed to store elastic potential energy, so that the right-side curtain body 30 can be unfolded. It should be noted that when the drive mechanism 40 drives the X-ray source component 200 to move to the right along the extension direction of the arc-shaped stroke cavity 10a, the two winding mechanisms 20 operate in opposite ways.

[0050] Please see Figure 5 In some embodiments, the curtain device 100 further includes a stop 50, which is disposed at opposite ends of the arc-shaped guide rail 11 along its length and is used to abut against the moving component 41 to prevent the moving component 41 from disengaging from the arc-shaped guide rail 11. The stop 50 may abut against the moving component 412, or it may abut against the connecting member 411, to limit the movement of the moving component 41 from disengaging from the arc-shaped guide rail 11. With this configuration, the stop 50 limits the travel distance of the moving component 41, ensuring that the moving component 41 always moves on the arc-shaped guide rail 11, preventing the moving component 41 from disengaging from the arc-shaped guide rail 11, avoiding damage to the curtain device 100, and improving the safety and reliability of the curtain device 100.

[0051] Please see Figure 7In some embodiments, the curtain device 100 further includes multiple reinforcing members 60, all connected to the curtain body 30 and spaced apart along the length of the curtain body 30. Each reinforcing member 60 extends along the width of the curtain body 30. The reinforcing members 60 increase the rigidity of the curtain body 30 in the length direction, further preventing the curtain body 30 from collapsing in the middle. Furthermore, the reinforcing members 60 increase the overall weight of the curtain body 30 to a certain extent, reducing the possibility of swaying during unfolding or closing, and enhancing the structural strength and stability of the curtain body 30. It should be noted that the specific form of the reinforcing members 60 is not specifically limited in this application. For example, the reinforcing member 60 can be a reinforcing rib, a reinforcing block, etc. Reinforcing ribs are typically made of high-strength materials such as metal or plastic, which effectively enhances the rigidity and stability of the curtain body 30.

[0052] Furthermore, in some embodiments, the spacing between two adjacent reinforcing members 60 is equal; that is, multiple reinforcing members 60 are evenly spaced; that is, multiple reinforcing members 60 are evenly spaced along the length of the curtain body 30. This arrangement makes the force on the curtain body 30 more balanced in various parts, avoiding tearing caused by uneven force distribution, and helping to improve the safety and reliability of the curtain body 30. In this application embodiment, the spacing between two adjacent reinforcing members 60 is not specifically limited; for example, the spacing between two adjacent reinforcing members 60 can be 9cm, 10cm, 12cm, etc.

[0053] In some embodiments, such as Figure 7 As shown, each reinforcing member 60 has a protective element 70 on the side facing away from the curtain body 30. Furthermore, the coverage area of ​​the protective element 70 is larger than that of the reinforcing member 60, so that the protective element 70 completely covers the reinforcing member 60. In other words, the reinforcing member 60 is sandwiched between the curtain body 30 and the protective element 70. The protective element 70 prevents the reinforcing member 60 from scratching the user, thus improving the safety of the curtain body 30 and the curtain device 100. The protective element 70 can be made of a flexible material, such as non-woven fabric, polyester, or polyester fiber, so as not to affect the opening or closing operation of the curtain body 30.

[0054] In some embodiments, the extension length of the reinforcing member 60 is equal to the width of the curtain body 30. This maximizes the length of the reinforcing member 60, ensuring it fully covers the width of the curtain body 30, thereby further enhancing the overall rigidity and stability of the curtain body 30. Furthermore, in this example, the two ends of the reinforcing member 60 in the extension direction can be aligned with the two edges in the width direction of the curtain body 30, preventing the reinforcing member 60 from exceeding the range of the curtain body 30 and affecting its normal use.
