Description

Technical Field

[0002] An X-ray imaging device is a medical device that can irradiate an object to be detected with X-rays and obtain an image. In a type of suspended X-ray imaging device, the X-ray emitting head is mounted on a suspension device, and the suspension device is suspended on a suspension base. Since multiple functional modules are usually integrated in the suspension device, such as a driving motor set for outputting a lifting driving force to control the lifting of the head, a rope assembly for pulling the head up and down, a balancing device for balancing the head, and a moving driving motor set for driving the suspension device to move on the suspension base, etc. In the existing suspension device, due to the large volume of these functional modules, the overall volume of the suspension device is huge, especially in terms of the thickness in the vertical direction, it appears particularly bulky.

Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment, and do not mean that they are necessary sequences, unless it is stated that a certain sequence must be followed.

[0080] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. The "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connections (couplings).

[0081] The present application provides an X-ray imaging device and its suspension device (in some embodiments, the suspension device can also be referred to as a trolley, suspension trolley, trolley assembly, or other names). By accommodating at least one functional module in the indicator lamp assembly, the compactness between the functional module and the indicator lamp assembly is improved, thereby reducing the thickness of the suspension device in the vertical direction. Moreover, the state of the X-ray imaging device is displayed through the light of the indicator lamp assembly, facilitating the user to intuitively understand the state of the X-ray imaging device.

[0082] In some embodiments, please refer to Figure 1-4 , the suspension device 1 includes a suspension bracket 110, a bottom case 120, a functional module, and an indicator light assembly 130. In addition, the suspension device 1 may also have other related components as needed, and these related components can refer to the prior art.

[0083] Please refer to Figure 1-4 , the suspension bracket 110 serves as the support foundation of the entire suspension device 1, and other components within the suspension device 1 can be directly or indirectly mounted on the suspension bracket 110. The suspension bracket 110 can be designed as a frame structure, such as a square frame or a frame structure of other shapes. In addition, the suspension bracket 110 can also adopt the bracket structure in various existing suspension structures. In some embodiments, the suspension bracket 110 can be made of sheet metal to increase the strength of the suspension bracket 110.

[0084] In some embodiments, the suspension bracket 110 can be connected to a suspension base, thereby suspending the entire suspension device 1 on the suspension base. The suspension base can be a sky rail assembly, a ceiling, a gantry structure, or other structures capable of suspending the machine head. Among them, the suspension device 1 can be fixed on the suspension base or can also be installed on the suspension device 1 in a movable manner. The moving manner of the suspension device 1 on the suspension base can adopt but is not limited to translation, rotation, and / or lifting, etc.

[0085] Please refer to Figure 1 , in some embodiments, the suspension base is a sky rail assembly 2, and the sky rail assembly 2 is installed on the ceiling of the detection room or other places. The sky rail assembly 2 includes an upper sky rail assembly 22 and a lower sky rail assembly 21. Among them, the suspension device 1 is installed on the lower sky rail assembly 21 and can translate on the lower sky rail assembly 21. In a specific structure, the suspension bracket 110 can be directly or indirectly installed on the lower sky rail assembly 21, thereby realizing the connection between the entire suspension device 1 and the lower sky rail assembly 21. The lower sky rail assembly 21 and the suspension device 1 are installed on the upper sky rail assembly 22 as a whole and can translate on the upper sky rail assembly 22. The assembly structure between the suspension device 1 and the lower sky rail assembly 21 and the upper sky rail assembly 22 can be realized by referring to the prior art and will not be elaborated here.

[0086] Please refer to Figure 2-5 , in some embodiments, the bottom case 120 covers the suspension bracket 110 from bottom to top and is fixedly connected to the suspension bracket 110. The bottom case 120 can form the outer shell of the entire suspension device 1 to form a neat appearance and can enclose each component installed on the suspension bracket 110.

[0087] This functional module is a module for implementing a certain function in the suspension device 1. In the suspension device 1, it may have one or more functional modules, and these functional modules are respectively used to implement different functions. These functional modules are directly or indirectly installed on the suspension bracket 110, with the suspension bracket 110 as the support structure. For example, in some embodiments, this functional module is at least one of the lifting drive motor set 141 for driving the movement of the cable drum, the cable drum 142 for winding the cable, the translation drive motor set 143 for driving the suspension device 1 to move on the suspension base, and the balancing device 144 for balancing the position of the machine head in the vertical direction.

[0088] Please refer to Figure 4 and 5 , in some embodiments, the bottom shell 120 has a cavity, which can be used to accommodate the various components on the suspension device 1, so as to cover these components from bottom to top. The bottom shell 120 has a first opening 121, and the first opening 121 is used to install the indicator light assembly 130. The indicator light assembly 130 includes a lamp shade 131 and a light emitting unit 132. The lamp shade 131 is buckled on the first opening 121 from bottom to top, and the light emitting unit 132 is arranged inside the lamp shade 131. The light emitting unit 132 can be, but is not limited to, LEDs or other types of light emitting devices. At least the bottom wall part of the lamp shade 131 can be made of a light transmissive material to facilitate the light to pass through the lamp shade 131.

[0089] In this embodiment, the indicator light assembly 130 is added, and the indicator light assembly 130 can display the state of the X-ray imaging device through the light, which is convenient for the user to intuitively understand the state of the X-ray imaging device.

[0090] Through the first opening 121, the cavity inside the bottom shell 120 can be communicated with the cavity inside the lamp shade 131, so as to form an installation space. In order to save space, in some embodiments of the present application, at least one functional module is installed above the first opening 121, and the bottommost part of the functional module extends downward through the first opening 121 and is accommodated in the cavity of the lamp shade 131. The space inside the lamp shade 131 can be used to accommodate the functional module, thereby reducing the occupation of the cavity space inside the bottom shell 120 by the functional module, and further facilitating the reduction of the thickness of the suspension device 1 in the vertical direction, making its appearance more thin and light, and visually more flat. Moreover, placing a part of the functional module inside the cavity of the lamp shade 131 can make the structure between the lamp shade 131 and the functional module more compact, and also contribute to reducing the volume of the suspension device 1.

[0091] Please refer to Figure 4 , in some embodiments, the lamp shade 131 protrudes downward from the bottom shell 120. From the overall appearance, it forms a shape similar to the "cockpit" of a spaceship, making the overall appearance of the suspension device 1 more thin, light and flexible visually.

[0092] In some embodiments, the functional modules partially placed in the cavity of the lamp housing 131 can be functional modules with relatively large volumes, especially the functional modules with relatively large dimensions in the vertical direction after being installed on the suspension bracket 110. In the original structure, since the bottom shell 120 needs to completely cover all the functional modules from bottom to top, when a certain functional module has a relatively large dimension in the vertical direction, it will cause an increase in the covering thickness of the bottom shell 120, thereby making the entire suspension device 1 thicker in the vertical direction. When the bottom of the functional module with a relatively large volume is placed in the cavity of the lamp housing 131, the part remaining in the bottom shell 120 becomes less, and thus the space that the bottom shell 120 needs to cover also becomes smaller, especially the space that needs to be covered in the vertical direction. Therefore, the entire suspension device 1 can be made thinner in the vertical direction and visually lighter.

[0093] Furthermore, generally among the functional modules of the suspension device 1, the balancing device 144 (which can also be referred to as a balancer) has a relatively large dimension in the vertical direction. Therefore, please refer to Figure 4 , in some embodiments, specifically, the balancing device 144 is installed above the first opening 121, and the lowermost part of the balancing device 144 (i.e., the part of the balancing device 144 located at the lowest position in the vertical direction) extends downward out of the first opening 121 and is received in the cavity of the lamp housing 131. In this embodiment, the space inside the lamp housing 131 can be utilized to accommodate the balancing device 144, thereby reducing the occupation of the inner cavity space of the bottom shell 120 by the balancing device 144, and further facilitating the reduction of the thickness of the suspension device 1 in the vertical direction and making its appearance more lightweight and thin.

[0094] Generally, the balancing device 144 has a length direction and a width direction. Among them, the length direction of the balancing device 144 is the direction with the largest dimension of it, and the width direction is the direction perpendicular to the length direction. Please refer to Figure 2 and 4 , in some embodiments, the balancing device 144 is placed obliquely relative to the vertical direction, so that the length direction A1 of the balancing device 144 forms an acute angle a with the vertical direction A2, in order to reduce the dimension of the balancing device 144 in the vertical direction A2. The schematic illustration of the specific acute angle a can be seen in Figure 4 as shown. In this way, the overall dimension of the balancing device 144 in the vertical direction A2 can be reduced, and further the thickness of the entire suspension device 1 can be reduced.

[0095] Furthermore, after adding the indicator light assembly 130, the user can more intuitively observe the state of the X-ray imaging device. Among them, the indicator light assembly 130 can be set to different display states according to different states of the X-ray imaging device. For example, in some embodiments, the light can be set as:

[0096] When the head is on standby, if the head is in a non-following state at this time, the indicator light assembly 130 displays blue light + breathing effect; if the head is in a following state at this time, the indicator light assembly 130 displays white light + breathing effect;

[0097] When the head is working, when the head moves, if it is in a non-following state at this time, the indicator light assembly 130 displays blue light + constant on; if it is in a following state at this time, the indicator light assembly 130 displays white light + constant on;

[0098] When the head is exposed, the indicator light assembly 130 displays green light for 2 seconds + yellow light for 0.5 seconds;

[0099] When the head is turned off, the indicator light assembly 130 displays blue light + gradual fade of the light.

[0100] Of course, the above is only an example of a lighting display mode of the indicator light assembly 130. In other embodiments, for different states of the head, the indicator light assembly 130 can also be designed in other lighting display modes.

[0101] The indicator light assembly 130 can be directly or indirectly installed on the bottom case 120 or the suspension bracket 110, and the installation method can be fixed or non-fixed. And the fixed can be detachable fixed or non-detachable fixed. The fixing method can be but not limited to snap connection, screw fixing, screw threading fixing, bonding, welding, and interference fit, etc.

[0102] Please refer to Figure 6 and 7 , in some embodiments, the wall of the first opening 121 has a ring of clamping platforms 1211. The lamp shade 131 has a plurality of buckles 1311 for clamping on the clamping platforms 1211. The clamping platform 1211 is provided with a disassembly and assembly notch 1212, and the buckle 1311 can pass through the disassembly and assembly notch 1212 from bottom to top and move above the clamping platform 1211 to form a clamping connection. When the buckle 1311 is rotated above the clamping platform 1211, the clamping platform 1211 can support the clamping connection and hold the lamp shade 131 on the bottom case 120. When the lamp shade 131 needs to be disassembled, rotate it in the reverse direction of the installation direction, and the buckle 1311 can be moved to the disassembly and assembly notch 1212 to remove the lamp shade 131.

[0103] Please refer to Figure 6 , in some embodiments, there are four (or other numbers) buckles 1311 evenly distributed around the top of the lamp shade 131. Correspondingly, the clamping platform 1211 has four (or other numbers) disassembly and assembly notches 1212 corresponding to the buckles 1311 for quick disassembly and installation with the lamp shade 131.

[0104] After the buckle 1311 is inserted into the disassembly and assembly notch 1212, in order to prevent the buckle 1311 from rotating too much during installation, in some embodiments, the card table 1211 may have a position-in-place prompting structure provided on the movement path of the buckle 1311 to prompt the user that the buckle 1311 has moved into place. This position-in-place prompting structure is used to provide a different feel to the installer compared to normal rotation, thereby prompting the installer that the rotation angle is in place. Based on this, the position-in-place prompting structure can adopt various structures that can provide different feels, such as a groove structure, a protrusion structure, a friction structure, a magnetic attraction structure, an uneven structure, and other structures.

[0105] Please refer to Figure 6 , in some embodiments, the position-in-place prompting structure is a protrusion 1213 provided on the card table 1211. The protrusion 1213 has a certain distance from the disassembly and assembly notch 1212. The height of the protrusion 1213 is designed to allow the lamp shade 131 to slide over the protrusion 1213, but the installer needs to provide a greater rotational force, thereby providing a different rotational feel. Of course, in other embodiments, the protrusion 1213 can also be replaced with the above-mentioned groove structure, protrusion 1213 structure, friction structure, magnetic attraction structure, uneven structure, and other structures. The friction structure is a structure with a friction force different from that of the normal rotation path (i.e., the area on the card table 1211 from the disassembly and assembly notch 1212 to the position-in-place prompting structure). For example, the friction structure can be a friction member with a greater friction force (such as silicone, etc.).

[0106] In addition, in order to further prevent the buckle 1311 from rotating too much during the installation of the lamp shade 131, in some embodiments, the card table 1211 has a stop structure provided on the movement path of the buckle 1311 to limit the movement stroke of the buckle 1311.

[0107] Please refer to Figure 6 , in some embodiments, the stop structure is a stop block 1214 provided on the card table 1211, and the stop block 1214 can prevent the buckle 1311 from moving along its movement path. Of course, in other embodiments, the stop structure can also be a groove, a magnetic attraction structure, a detachable bonding structure (such as Velcro), etc., which can prevent the buckle 1311 from continuing to rotate.

[0108] Of course, in some other embodiments, the position-in-place prompting structure can also serve as the stop structure at the same time, or the stop structure can serve as the position-in-place prompting structure at the same time. For example, in Figure 6 the shown stop structure can also serve as the position-in-place prompting structure at the same time, and the original position-in-place prompting structure can be omitted.

[0109] Further, in the indicator light assembly 130, the light-emitting unit 132 can be fixed inside the lamp cover 131, and the light-emitting unit 132 emits light by virtue of the light-transmitting property of the lamp cover 131. In some embodiments, the lamp cover 131 can adopt the IML process and be made of a translucent material. A translucent thin sheet can be wrapped around its exterior, and patterns are screen-printed on the translucent thin sheet. The light of the lamp can be projected from the hollowed areas in the patterns.

[0110] Please refer to Figure 6 , in some embodiments, the inner wall of the lamp cover 131 has a mounting wall body 1312 protruding 1213 towards the first opening 121 in a circular shape, and the light-emitting unit 132 is fixedly mounted on the mounting wall body 1312. In this embodiment, the strip-shaped light-emitting unit 132 can be arranged to surround the mounting wall body 1312, thereby forming a circumferentially surrounding light-emitting area to improve the lighting effect.

[0111] In addition, the light-emitting unit 132 can also be mounted in the lamp cover 131 in other ways. For example, multiple light-emitting units 132 are separately arranged in different places of the lamp cover 131. Or, the light-emitting unit 132 can also adopt a surface light source, and the surface light source is laid flat in the lamp cover 131.

[0112] In order to further reduce the thickness of the suspension device 1, in some embodiments, it can also be achieved by optimizing the arrangement of each functional module.

[0113] Please refer to ​ , in some embodiments, the suspension device 1 further includes a lifting drive motor set 141, a cable drum 142, a translation drive motor set 143, a balancing device 144, a cable 145, and a telescopic assembly 146. The bottom shell 120 has a second opening 122. The telescopic assembly 146 is installed on the suspension bracket 110 and extends downward through the second opening 122 for installing the machine head 3. The lifting drive motor set 141, the cable drum 142, the balancing device 144, and the translation drive motor set 143 are all directly or indirectly installed on the suspension bracket 110 and are supported by the suspension bracket 110. The cable 145 is wound around the cable drum 142 and is connected to the telescopic assembly 146. The telescopic assembly 146 can have a telescopic structure. The lifting drive motor set 141 drives the cable drum 142 to move to wind and release the cable 145. By controlling the cable 145, the telescopic assembly 146 can be contracted upward and extended downward. The balancing device 144 is connected to the cable 145 for balancing the position of the machine head 3 in the vertical direction. The translation drive motor set 143 is used to drive the entire suspension device 1 to translate on a suspension base (such as the lower track assembly 21 in the track assembly 2).

[0114] In order to obtain a suspension device 1 with a smaller thickness, please refer to ​ and 4, in some embodiments, in the horizontal direction, the lifting drive motor set 141, the cable drum 142, the translation drive motor set 143 and the balance device 144 are arranged side by side, so as to avoid the increase in the thickness of the suspension device 1 caused by the different heights of each functional module in the vertical direction, thereby reducing the size of the entire suspension device 1 in the vertical direction.

[0115] Further, please refer to ​ and 4 , at least one of the lifting drive motor set 141 and the translation drive motor set 143 adopts a straight cylinder structure of a motor plus a planetary reducer; the lifting drive motor set 141 and the translation drive motor set 143 are arranged side by side between the balance device 144 and the cable drum 142, and the lifting drive motor set 141 and the translation drive motor set 143 face in opposite directions. This structure hides the lifting drive motor set 141 and the translation drive motor set 143 in the space between the balance device 144 and the cable drum 142, making full use of the space between the balance device 144 and the cable drum 142, and moreover, the lifting drive motor set 141 and the translation drive motor set 143 face in opposite directions, forming a side-by-side structure. The structures between the functional modules are compact, which is beneficial to reducing the size of the suspension device 1 in the ​ shown left-right direction, and further reducing the overall volume of the suspension device 1.

[0116] On the other hand, usually when installing the suspension device 1, the suspension bracket 110 and each functional module are installed first, and finally the bottom shell 120 is installed on the suspension bracket 110. However, since the suspension bracket 110 is suspended, the bottom shell 120 needs to be installed upward, and this installation method is very inconvenient, especially inconvenient to fix the bottom shell 120.

[0117] To solve the problem of inconvenient installation of the bottom shell 120, in some embodiments of the present application, the suspension bracket 110 has a first pre-positioning structure and a first fixing structure. The bottom shell 120 has a second pre-positioning structure and a second fixing structure. The first pre-positioning structure and the second pre-positioning structure are used to pre-position the suspension bracket 110 and the bottom shell 120, and the first fixing structure and the second fixing structure are used to further fixedly connect the suspension bracket 110 and the bottom shell 120 after pre-positioning.

[0118] Among them, the pre-positioning is used to form a preliminary positioning between the bottom shell 120 and the suspension bracket 110, so that the bottom shell 120 is temporarily suspended on the suspension bracket 110. After pre-positioning, the final fixation is achieved through the fixing structure.

[0119] In order to better achieve pre-positioning, in some embodiments, the first pre-positioning structure and the second pre-positioning structure are quick-release positioning structures. The quick-release positioning structure is a structure that can be assembled and disassembled without the use of tools, and can be, for example, but not limited to, quick-release snap connections, threaded rotary connections, magnetic fixing, detachable adhesives, interference fits, or other detachable structures, etc.

[0120] For example, please refer to ​ , in some embodiments, at least one of the first pre-positioning structure 111 and the second pre-positioning structure 123 has a cavity structure 1231, and the other has an insert 1111. Pre-positioning is achieved through insertion between the cavity structure 1231 and the insert 1111. Among them, the cavity structure 1231 can be, but not limited to, a pre-positioning hole, a groove, or a cavity, etc. The insert 1111 can be, but not limited to, a pin, a protrusion 1213, or a cylinder, etc. For example, please refer to ​ , in some embodiments, the first pre-positioning structure 111 has a cavity structure 1231, and the second pre-positioning structure 123 has an insert 1111. Of course, in other embodiments, the two can also be interchanged.

[0121] In some embodiments, please refer to ​ 、 11 , in this insertion structure, the size of the cavity structure 1231 in the horizontal direction is greater than its size in the vertical direction, so that the insert 1111 can adjust its position in the horizontal direction. In this way, not only is it more convenient to insert the insert 1111 into the cavity structure 1231, but also when fixing later, the position of the bottom shell 120 can be translated relative to the suspension bracket 110 according to the needs of assembly, making it easier to achieve fixation.

[0122] Please refer to ​ , the insert 1111 is a pin extending in the horizontal direction, and the cavity structure 1231 is an oblong hole arranged in the horizontal direction. The pin can be translated within the oblong hole to adjust its position.

[0123] Furthermore, in some embodiments, the cavity structure 1231 is provided on the bottom shell 120, and the insert 1111 is provided on the suspension bracket 110. Or, in other embodiments, the two can also be interchanged.

[0124] Specifically, please refer to ​ 、 11 , in some embodiments, the cavity structure 1231 is provided on a spring piece. The spring piece can have a deformation ability. When pre-positioning, the insert 1111 can abut against the spring piece to deform the spring piece and insert the insert 1111 into the cavity structure 1231. Among them, ​ and 11Two different elastic pieces are shown, which rely on the deformation of their own elastic materials. In addition, in some other embodiments, the elastic piece may also include a sheet body that is not easily deformed and an elastic member (such as a spring, etc.) for driving the movement of the sheet body, so that the sheet body has elasticity by means of the elastic member.

[0125] Further, please refer to ​ 、 11 , in some embodiments, one side of the elastic piece facing the direction of the insert 1111 forms a guiding surface 1232, and the guiding surface 1232 inclines upward and away from the insert 1111. When pre-positioning from bottom to top, the insert 1111 can abut against the guiding surface 1232, deform the elastic piece, and move along the guiding direction of the guiding surface 1232 towards the cavity structure 1231, so that the insert 1111 is inserted into the cavity structure 1231.

[0126] In addition, in order to form a more stable pre-positioning, please refer to ​ and 5 , the first pre-positioning structure 111 (in the illustrated embodiment, the first pre-positioning structure 111 is provided on the suspension bracket 110) is multiple (such as four or other quantities), and it is distributed along the circumferential direction of the suspension bracket 110; the second pre-positioning structure 123 (in the illustrated embodiment, the second pre-positioning structure 123 is provided on the bottom case 120) is multiple (such as four or other quantities), and it is distributed on the inner circumferential surface of the bottom case 120, so as to achieve pre-positioning from different positions in the circumferential direction and form a more stable pre-positioning.

[0127] For the sake of a neat appearance, in some embodiments, in the horizontal direction, neither the first pre-positioning structure 111 nor the second pre-positioning structure 123 exceeds the bottom case 120, so that the first pre-positioning structure 111 and the second pre-positioning structure 123 will not protrude beyond the bottom case 120 in the horizontal direction, which is not only neat in appearance but also not easy to scratch the installer.

[0128] The first fixing structure and the second fixing structure can adopt various structures that can achieve fixation, especially detachable fixing structures. For example, but not limited to, snap fixing or screw fixing, etc.

[0129] In order to form a more stable fixation, please refer to ​ and 5 , the first fixing structure 112 (in the illustrated embodiment, the first fixing structure 112 is provided on the suspension bracket 110) is multiple (such as four or other quantities), and it is distributed along the circumferential direction of the suspension bracket 110; the second fixing structure 124 (in the illustrated embodiment, the second fixing position structure is provided on the bottom case 120) is multiple (such as four or other quantities), and it is distributed on the inner circumferential surface of the bottom case 120, so as to achieve fixation from different positions in the circumferential direction and form a more stable fixation.

[0130] Please refer to​ and 5 In some embodiments, the first fixing structure 112 is specifically a first mounting seat protruding outward 1213 on the suspension bracket 110, and the second fixing structure 124 is a second fixing seat protruding inward 1213 on the bottom case 120. The first mounting seat and the second mounting seat can be fixedly connected by screws.

[0131] In some embodiments, the first fixing structure 112 and the second fixing structure 124 can be sheet metal parts to increase strength.

[0132] For the sake of a tidy appearance, in some embodiments, in the horizontal direction, neither the first fixing structure 112 nor the second fixing structure 124 extends beyond the bottom case 120, so that the first fixing structure 112 and the second fixing structure 124 do not protrude outside the bottom case 120 in the horizontal direction. This not only makes the appearance tidy but also is not easy to scratch the installer.

[0133] On the other hand, in some embodiments of the present application, an X-ray imaging device is further provided. Please refer to ​ , the X-ray imaging device includes the suspension device 1 as shown in any one of the above and a machine head 3 for emitting X-rays. The machine head 3 is mounted on the suspension device 1.

[0134] The above uses specific examples to elaborate on 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 technical field to which the present application pertains, based on the idea of the present application, several simple deductions, deformations or substitutions can also be made.
