[0002] In medical equipment, DC power supply systems play a crucial role, primarily powering multiple sub-modules within the system. The power requirements of different modules vary considerably.

[0003] Current DC power distribution solutions employ an integrated design, providing power to multiple loads through a centralized DC power supply. While this integrated design can effectively meet system requirements initially, its scalability and flexibility are poor. When encountering load changes or demand adjustments, it is often necessary to modify the power output port cables or redesign the power supply equipment to adapt to the new power demands.

Detailed Implementation

[0058] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0059] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0060] As medical equipment systems (such as MRI scanners) become increasingly complex, the requirements for DC power supply systems are becoming more demanding. In modern MRI (Magnetic Resonance Imaging) equipment, different components have varying power requirements, including strong magnetic field systems, radio frequency systems, gradient power supplies, and auxiliary control systems. These components have different requirements for power supply stability, accuracy, and power supply capacity.

[0061] As the system continues to upgrade and expand, new DC components need to be connected to the power distribution system. This requires the power distribution system to be able to quickly and flexibly provide power support for the new loads without requiring a large-scale redesign of the entire system.

[0062] The first direction in this utility model is Figure 11 The Z direction is shown in the diagram, and the second direction is the X direction shown in the diagram.

[0063] To solve the above technical problems, such as Figure 1-10 As shown, in order to achieve the above-mentioned and other related objectives, one embodiment of the present invention provides a DC power distribution device for a medical imaging system, including a housing 10, a DC output interface 20, and a movable terminal 30.

[0064] The housing 10 is provided with a plug-in portion 60. Both the housing 10 and the plug-in portion 60 are made of insulating material. The plug-in portion 60 can be inserted into a power supply unit (the DC power distribution rail in this application) for providing power along a first direction; that is, the plug-in portion 60 is used to connect with the DC power distribution rail. The plug-in portion 60 supports quick docking with the DC power distribution rail, improving the overall scalability and flexibility of the system. Specifically, the housing 10 can be a box-shaped structure, composed of multiple plates. The plug-in portion 60 is located on one plate of the housing 10 in the first direction, and is located on the outside of the housing 10 for easy insertion.

[0065] A DC output interface 20 is mounted on the housing 10. Specifically, the DC output interface 20 is located on the side of the housing 10 away from the plug-in portion 60, and is exposed on the outside of the housing 10. The DC output interface 20 serves as the output terminal for DC power, connecting to load devices or other modules to provide a stable power supply. Both the DC output interface 20 and the plug-in portion 60 are located at the center of the housing 10, parallel to a first direction, and are aligned in the first direction.

[0066] The movable terminal 30 is electrically connected to the DC output interface 20. The movable terminal 30 is disposed on the plug-in portion 60 and can be movably positioned relative to the plug-in portion 60. The movable terminal 30 can switch between a first position and a second position to connect or disconnect the power supply unit. The movable terminal 30 can be switched to different positions manually, automatically, or mechanically. This switching can be achieved through sliding, rotating, or locking. When the movable terminal 30 is switched to the working position, it establishes a connection with other electrical components through a conductive path. When switched to the disconnected position, the connection between the terminal and the circuit is interrupted, thereby achieving circuit isolation. The movable terminal 30 includes a positive terminal and a negative terminal; for equipment requiring grounding, a grounding terminal can be added.

[0067] like Figure 9 As shown, in the first position (i.e., the electrical connection disconnected position), the projection of the movable terminal 30 in the first direction is located within the projection area of ​​the plug portion 60 in the first direction. At this time, the movable terminal 30 is in the retracted position, and the circuit is disconnected. In this state, there is no electrical connection between the DC output interface 20 and the load. The DC distributor can be removed at this time.

[0068] like Figure 10 As shown, in the second position (i.e., the electrical connection position), the projection of the movable terminal 30 in the first direction protrudes beyond the projection area of ​​the plug portion 60 in the first direction. When the movable terminal 30 moves to the protruding position, the circuit is closed, and the DC output interface 20 supplies power to the load. At this point, the installation of the DC power distributor is complete.

[0069] In one specific embodiment of this utility model, a conductive ring 40 is provided on the side of the housing 10 near the movable terminal 30, and the conductive ring 40 is arranged around the circumference of the movable terminal 30. As a key component for electrical connection, the movable terminal 30 may generate electromagnetic interference during operation. This interference can not only affect the normal operation of surrounding electronic equipment but may also cause malfunctions in sensitive devices. The conductive ring 40, arranged around the circumference of the movable terminal 30, effectively creates a shielding layer around the terminal. This shielding layer can absorb and conduct away high-frequency interference signals generated by the terminal, effectively reducing electromagnetic leakage. The conductive ring 40 is specifically made of conductive cotton. The conductive cotton is flexible and elastic, forming a buffer protective layer between the movable terminal 30 and the housing 10, reducing the impact of mechanical vibration or external force on the terminal.

[0070] like Figure 1-5As shown in Embodiment 1, the plug-in portion 60 is fixedly connected to the housing 10, and the movable terminal 30 is rotatably connected to the housing 10. A rotating component such as a turntable 51 or a rotating shaft can be mounted on the housing, and the movable terminal 30 is fixedly connected to the turntable 51 or rotating shaft to achieve a rotatable connection with the housing 10. A drive unit 50 is also included on the housing 10. The drive unit 50 is used to drive the movable terminal 30 to switch between a first position and a second position. The drive unit 50 can be an exposed lever, wheel, button 53, or other component, which is then driven by an operator to rotate the movable terminal 30. Since the movable terminal 30 can switch between workstations and the drive unit 50 can be exposed, the switching of the movable terminal 30 does not require complex displacement space; it only relies on rotation or simple operation to achieve functional switching. Therefore, within a limited rack or panel space, multiple housings 10 can be tightly arranged, allowing for the placement of more power distribution devices.

[0071] like Figure 3-5 As shown, in Embodiment 1, the drive unit 50 includes a turntable 51, a connecting rod 52, and a button 53.

[0072] The turntable 51 is fixedly connected to the movable terminal 30. The axis of the turntable 51 is located in the first direction. Specifically, the turntable 51 is a disc structure embedded in one side plate of the housing. This means that the rotation of the turntable 51 directly controls the displacement or switching of the movable terminal 30. One end of the connecting rod 52 is connected to the circumferential area of ​​the turntable 51, and the button 53 is connected to the other end of the connecting rod 52. The connecting rod 52 can convert the pressing action into the rotation of the turntable 51 through gear and rack transmission, multi-link transmission, etc. Specifically, in this application, the two ends of the connecting rod 52 are respectively hinged to the turntable 51 and the button 53 to form a multi-link structure. When the operator presses the button 53, the button 53 transmits mechanical force through the connecting rod 52, activating the pushing and pulling action of the connecting rod system. This simple operation step can realize the switching of the working position of the movable terminal 30 through a mechanical structure.

[0073] like Figure 4 , 5As shown, in Embodiment 1, the button 53 is hinged to the housing 10 via a hinge shaft. A spring 54 is provided on the button 53. When the movable terminal 30 is in the first and second positions, the spring 54 is located on both sides of the hinge shaft axially. Specifically, the button 53 is a rocker arm structure with a central hinge, and the spring 54 is a tension spring. The two ends of the tension spring can be connected to the axis of the turntable 51 and the button 53, respectively. The connection end between the tension spring and the button 53 is located on the center line of the rocker arm, and the hinge shaft of the button 53 is located between the two ends of the tension spring. Thus, when the rocker arm structure swings, the tension spring will cross the hinge shaft, forming two triangles at the two ends of the button 53's swing. The two triangles are symmetrical about the line connecting the hinge shaft and the axis of the turntable 51. In this way, the spring 54 can provide limits at the two ends of the button 53's swing, corresponding to the first and second positions, respectively. Specifically, when button 53 swings to a position, the tension spring stretches and forms a limit at that position. As button 53 swings further, the tension spring will limit the position of button 53 through a triangular shape, ensuring that button 53 can remain stable at both work positions.

[0074] like Figure 6-8 As shown in Embodiment 2, the plug-in part 60 is rotatably connected to the housing 10. The plug-in part 60 can be connected to the housing 10 through a rotatable structure such as a rotating shaft, a disc, or a ring. Specifically, the plug-in part 60 includes a fixedly connected ring part 66, which is rotatably connected to the housing 10.

[0075] The movable terminal 30 is fixedly connected to the housing 10. Specifically, the inner ring of the annular portion 66 has a circular plate 11, which is fixedly connected to the housing 10 via a bracket structure. The movable terminal 30 is fixedly connected to the outer side of the circular plate 11, thus achieving a fixed connection relative to the housing 10. This means that the movable terminal 30 changes position as the housing 10 rotates. With this fixed connection, the movable terminal 30 does not require an independent drive device; its position can be switched by rotating relative to the insertion portion 60 through the rotation of the housing 10.

[0076] This eliminates the need for a complex drive structure; simply rotating the housing 10 allows for the switching of the movable terminal 30's position. During use, the plug-in portion 60 remains in the same position relative to the DC power distribution track. Rotating the housing 10 then drives the movable terminal 30 to rotate. This simple rotation allows the movable terminal 30 to switch from a first position to a second position; the angle and direction of rotation directly determine the terminal's position.

[0077] like Figure 1 , 2 As shown in Figures 6 and 7, the plug-in portion 60 includes a first insulating protective plate 61, a second insulating protective plate 62, and a third insulating protective plate 63.

[0078] The first insulating plate 61 is located on the side of the movable terminal 30 opposite to the second position. This ensures that the positive and negative polarities are clearly defined during terminal connection, thus avoiding the reverse polarity problem unique to DC systems. It provides an additional physical barrier to prevent accidental contact and incorrect orientation during operation. The second insulating plate 62 is located on the side of the movable terminal 30 away from the housing 10. This prevents the terminal from briefly contacting a non-target interface and causing a short circuit during insertion or removal of the movable terminal 30. The third insulating plate 63 is located on at least one side of the movable terminal 30, and its surface is perpendicular to the first insulating plate 61 and the second insulating plate 62. It provides isolation between terminals, preventing short circuits caused by contact between terminals of adjacent power distribution units.

[0079] like Figure 3 As shown, a guide unit is provided between the insertion part 60 and the movable terminal 30. The guide unit includes an arc-shaped guide rail 64 and a sliding part 31. The arc-shaped guide rail 64 is specifically an arc-shaped groove or hole, and the sliding part 31 is a limiting post inserted into the arc-shaped groove or hole. The arc-shaped guide rail 64 guides the movable terminal 30 along a predetermined path through the form of a curved track or channel, ensuring that the movable terminal 30 moves according to a specific trajectory. The sliding part 31 is composed of the limiting post inserted into the arc-shaped guide rail 64. Its function is to form a constraint with the guide rail through physical contact, ensuring that the movable terminal 30 does not deviate from the predetermined track and avoids misalignment or jamming. One of the arc-shaped guide rail 64 and the sliding part 31 is connected to the insertion part 60, and the other is connected to the movable terminal 30. The center of curvature of the arc-shaped guide rail 64 is the center of rotation of the movable terminal 30.

[0080] In one specific embodiment of this utility model, the arc of the arc-shaped guide rail 64 corresponds to an angle of 66 degrees. This 66-degree arc angle controls the maximum range of rotation of the movable terminal 30. This angle limitation ensures that the movable terminal 30 will not rotate beyond its design range, thereby avoiding improper installation or damage caused by excessive rotation. The 66-degree limitation provides optimal rotation space, satisfying the precise alignment requirements during terminal insertion and removal while avoiding unnecessary free rotation.

[0081] In one specific embodiment of this utility model, limiting portions are provided at both ends of the arc-shaped guide rail 64, and the limiting portions prevent the sliding portion 31 from disengaging from both ends of the arc-shaped guide rail 64. The limiting portion is a protrusion on the inner wall of the arc-shaped groove or hole, and the limiting is formed by the interference between the protrusion and the limiting post.

[0082] The housing 10 provides structural support and protection for the DC power distributor, ensuring that internal circuits and components are protected from external physical damage or environmental influences. Capacitors, indicator lights, fuses, and other components may also be housed within the housing 10. Capacitors smooth voltage fluctuations, reducing ripple or noise in the power supply. Indicator lights use different colors (such as green, red, and yellow) to reflect the current operating status of the equipment. For example, green indicates normal operation, red indicates a fault or warning condition, and yellow may indicate that the equipment is in standby or maintenance mode. Fuses automatically disconnect the circuit in the event of a short circuit or overload, protecting the equipment and circuit from damage. The housing 10 is specifically a rectangular box shape.

[0083] Different interfaces, fuses, capacitors and other components can be installed on the housing 10, which can effectively meet the changing power requirements of the back-end DC components and the development needs of the system, and can better adapt to diverse application scenarios and dynamically changing power demands.

[0084] like Figure 11 , 12 As shown, this utility model also discloses a DC power distribution track for a medical imaging system, including a housing 70 and a conductive part 80. The conductive part 80 is used to connect to a DC power supply, and the housing 70 may also be equipped with components such as capacitors, indicator lights, fuses, and power-off switches. The capacitors are used to smooth voltage fluctuations and reduce ripple or noise in the power supply. The indicator lights use different colors of light (such as green, red, yellow, etc.) to reflect the current operating status of the equipment. For example, green indicates that the equipment is operating normally, red indicates a fault or warning state, and yellow may indicate that the equipment is in standby or maintenance mode. The fuse automatically disconnects the circuit when a short circuit or overload occurs, protecting the equipment and circuit from damage. The housing 70 is specifically rectangular box-shaped.

[0085] like Figure 12 As shown, the housing 70 has a receiving cavity 71 inside, and the housing 70 has an insertion port 72 for inserting a DC power distributor along a first direction, which communicates with the receiving cavity 71 and the outside. The housing 70 can be made of insulating material or metal material. If metal material is used, an insulating layer 74 is also provided between the conductive part 80 and the housing 70, which ensures the electrical safety of the device.

[0086] like Figure 12 As shown, the conductive part 80 is disposed within the receiving cavity 71 and is capable of supplying power to the DC power distributor. The conductive part 80 is located to the side of the projection of the insertion port 72 in the first direction. The insertion port 72 allows external devices or terminals to connect to the internal conductive part 80, and the location of the conductive part 80 to the side of the insertion port 72 ensures that the terminal can accurately align with the conductive strip during insertion, guaranteeing stable current transmission. When the movable terminal 30 is in the second position, the movable terminal 30 is connected to the conductive part 80.

[0087] like Figure 11 , 12 As shown, in a specific embodiment of this utility model, the insertion port 72 is a strip-shaped opening arranged along a second direction, which is perpendicular to the first direction. The first direction typically represents the length of the connector or the main insertion direction, while the second direction, when perpendicular to the first direction, may represent the width of the insertion port or the way the connector is arranged laterally. The conductive part 80 includes a positive conductive strip and a negative conductive strip arranged along the second direction, which are respectively placed on both sides of the projection of the insertion port 72 in the first direction. The positive and negative conductive strips correspond to the positive and negative terminals of the movable terminal 30, respectively. The separately arranged conductive strips ensure that each terminal corresponds to its specific conductive strip, avoiding connection errors and improving ease of use and safety. The strip-shaped opening allows multiple DC power distribution units to be connected in the second direction.

[0088] like Figure 12 As shown, the positive and negative conductive strips are strip-shaped groove structures with opposite openings. The grooves are designed to accommodate the movable terminal 30, allowing the terminal to naturally enter the groove during insertion and removal, thus completing the connection.

[0089] like Figure 12 As shown, the width of the groove structure gradually decreases and then gradually increases from the groove opening towards the bottom. At the groove opening, the width is larger, facilitating smooth terminal insertion. As insertion progresses, the groove width gradually decreases, allowing the movable terminal 30 to make tight contact with the conductive strip near the bottom of the groove. Then, the groove width gradually increases again, which helps position the movable terminal 30, preventing displacement during connection and maintaining stable contact. The narrowest point at the groove opening is smaller than the terminal diameter, so the movable terminal 30 is clamped during insertion, ensuring good contact between the terminal and the conductive strip. This tight contact avoids poor contact problems and contributes to the stability of electrical transmission.

[0090] like Figure 13 As shown, this utility model also discloses a DC power distribution component for a medical imaging system, including the aforementioned DC power distribution rail and the aforementioned DC power distributor. That is:

[0091] The DC power distribution track includes a housing 70 and a conductive part 80. The housing 70 has a receiving cavity 71. The housing 70 has an insertion port 72 that connects the receiving cavity 71 to the outside. The conductive part 80 is disposed in the receiving cavity 71 and can provide power to the DC power distributor through the conductive part. The conductive part 80 is located to the side of the projection of the insertion port 72 in a first direction.

[0092] The DC power distributor includes a housing 10, a DC output interface 20, and a movable terminal 30. The housing 10 is provided with a plug-in portion 60 for inserting into the insertion port 72 along a first direction, and the DC output interface 20 is mounted on the housing 10. The movable terminal 30 is electrically connected to the DC output interface 20. The movable terminal 30 is disposed on the plug-in portion 60 and can be movably disposed relative to the plug-in portion 60. The movable terminal 30 can switch between a first position and a second position to enable the movable terminal 30 to be connected or disconnected from the conductive portion 80.

[0093] In the first position, the projection of the movable terminal 30 in the first direction is located within the projection area of ​​the plug portion 60 in the first direction, so as to avoid the conductive portion 80; and

[0094] In the second position, the projection of the movable terminal 30 in the first direction protrudes beyond the projection area of ​​the plug portion 60 in the first direction, so as to electrically connect the conductive portion 80.

[0095] In one specific embodiment of this utility model, a limiting groove 73 is provided on the outer shell 70, and the insertion part 60 includes a limiting clip 65 for inserting into the limiting groove 73 to form a rotation limiting. In the first embodiment above, the limiting clip 65 is provided on the outside of the shell 10, and in the second embodiment above, the limiting clip 65 is provided on the outside of the annular part 66, and the limiting groove 73 is a strip-shaped groove provided along the second direction. When the movable terminal 30 starts to rotate, the cooperation of the limiting groove 73 and the limiting clip 65 can keep the insertion part 60 fixed, preventing it from being driven by the movable terminal 30 due to friction.

[0096] In summary, the DC power distribution unit, DC power distribution track, and DC power distribution components proposed in this utility model can flexibly adjust the number of power distribution units according to actual load requirements. This means that when the load increases, more power distribution units can be added, and when the load decreases, fewer units can be added, thereby achieving dynamic adjustment of the system. As demand increases, the power distribution capacity of the original system may not be able to meet the demand. By using a modularly designed DC power distribution track and device, users can easily expand the power distribution network. By installing multiple DC power distribution units on the track, each device is connected to the track and other equipment to form a highly integrated DC power distribution system. Traditional power distribution networks usually require complex wiring and equipment installation to achieve power distribution. However, by adopting integrated DC power distribution units and tracks, the power distribution network can be significantly simplified. Since the DC power distribution units are connected through the track, the installation and disassembly of the entire system become extremely simple. Each power distribution device can be modularly installed on the track; users only need to insert the device into the track to complete the installation, without the need for complex tools or rewiring. Each DC power distribution unit, as an independent module, can limit the impact of a fault on the entire power distribution system in the event of a failure.
