Description
TECHNICAL FIELD
[0001] The utility model relates to the field of medical equipment, especially to a charging device, a charging rack comprising the same and a mobile X-ray machine. BACKGROUND
[0002] X-ray receiving devices of medical equipment such as mobile DR (Mobile Digital Radiography, also known as "mobile X-ray machine") generally have two states of working and charging. After the working is finished, these medical equipment need to be charged to reserve the power required for the next work.
[0003] The charged objects are usually stored in the charging rack for charging. For some charged objects, the charging port is arranged on the back of the equipment. When the charged object is stored in the charging rack, the charging port is also located in the charging rack. In order to prevent the charging port from being damaged by exposure, the charging plate connected to the charging port for charging the charged object also needs to be arranged in the charging rack.
[0004] When the charged object is put into the charging rack, the charging plate needs to move forward to contact the charging port; when the charged object is removed from the charging rack, the charging plate needs to retreat to be away from the charging port. Generally, the space inside the charging rack is very limited, and how to make the charging plate complete the above-mentioned movement in the limited space to charge the charged object becomes a difficult problem. SUMMARY
[0005] The utility model aims at providing a charging device which can be arranged in a limited space and charge the charged object in the limited space.
[0006] Still another object of the utility model is to provide a charging rack comprising the above-mentioned charging device, which can charge the charged object.
[0007] Another object of the utility model is to provide a mobile X-ray machine comprising the above-mentioned charging rack, which can charge the X-ray receiving device in the charging rack.
[0008] The utility model provides a kind of charging device, including bottom plate, connecting rod assembly and charging plate. Bottom plate is movably connected to support along first direction and its opposite direction. Connecting rod assembly includes first connecting rod, second connecting rod and connecting shaft. The first end of first connecting rod is rotatably connected to support around first axis line, and first axis line is perpendicular to first direction. The first end of second connecting rod is movably connected to support along first direction and its opposite direction. First connecting rod and second connecting rod are rotatably sleeved in connecting shaft around second axis line to form scissor fork structure. The second end of first connecting rod is movably connected to charging plate along first direction and its opposite direction. The second end of second connecting rod is rotatably connected to charging plate around third axis line, and third axis line is parallel to first axis line.
[0009] By setting the scissors structure, when the base plate moves along the first direction, the scissors structure drives the charging plate to move to contact the charged object. The charging device can be set in a limited space to charge the charged object in the limited space.
[0010] In another illustrative embodiment of the charging device, the linkage assembly includes two first linkages and two second linkages to form two parallelly arranged scissors structures. Thereby, the stability of the charging device is improved.
[0011] In another illustrative embodiment of the charging device, the charging plate is provided with a first long hole. The support is provided with a second long hole. The second end of the first linkage is inserted into the first long hole and can move in the first long hole along the first direction and the opposite direction thereof. The first end of the second linkage is inserted into the second long hole and can move in the second long hole along the first direction and the opposite direction thereof. The charging device has simple structure, is easy to maintain, and is also conducive to improving the buffering performance.
[0012] In another illustrative embodiment of the charging device, the linkage assembly further includes a first spring. One end of the first spring is connected to the support, and the other end is connected to the first end of the second linkage to apply a force along the first direction to the first end of the second linkage. Thereby, the stability of the charging device is improved.
[0013] In another illustrative embodiment of the charging device, the base plate is provided with a third long hole extending along the first direction. The support includes a fixing block. The fixing block is inserted into the third long hole to enable the base plate to move along the first direction and the opposite direction thereof relative to the support. The charging device has simple structure and is easy to maintain.
[0014] In another illustrative embodiment of the charging device, the base plate further includes a supporting portion extending along a second direction to support the charged object, and the supporting portion is arranged at the front end of the base plate along the first direction. The second direction is perpendicular to the first direction and the first axis. The charging device can place the charged object on the supporting portion, so that the base plate moves along the first direction relative to the support under the gravity of the charged object, so that the charging plate contacts the charged object without additional operation of the charging device.
[0015] In another illustrative embodiment of the charging device, a second spring is further included. One end of the second spring is connected to the base plate, and the other end is connected to the support to apply a force along the opposite direction of the first direction to the base plate. Thereby, after the charged object leaves the base plate, the base plate moves along the opposite direction of the first direction under the elastic restoring force of the second spring.
[0016] In another exemplary embodiment of the charging device, a buffer is further included. The buffer is fixed to the support. The bottom plate further includes a buffer portion extending in a direction opposite to the second direction. The second direction is perpendicular to the first direction and the first axis. When the bottom plate moves in the first direction until the buffer portion abuts against the buffer, the buffer can be compressed under the abutment of the buffer portion, and the elastic restoring force of the buffer can slow down the movement speed of the bottom plate in the first direction. Thus, the vibration caused by the rapid falling of the bottom plate can be buffered, and the buffering performance and stability of the charging device are improved.
[0017] In another exemplary embodiment of the charging device, a charging module electrically connected to the charging plate is further included. The charging module includes a switch, which is a microswitch. When the bottom plate moves to abut against the roller of the switch, the bottom plate pushes the roller in a third direction perpendicular to the first direction, so that the elastic sheet of the switch is deformed to push the contact of the switch to move in the third direction, so as to close the switch to charge the charged object. This structure can automatically close the switch when the bottom plate falls in the first direction to the switch, without the need for an operator to manually close the switch, thereby simplifying the charging operation.
[0018] In another exemplary embodiment of the charging device, an in-place detection module for detecting whether the charged object is placed in the support is further included, and the in-place detection module is a microswitch. Thus, the operator can easily check whether the charged object is placed in the support.
[0019] The utility model also provides a charging rack, including support, above charging device and shell. The inside of support is used for storing charged object. Charging device sets up in the outside of support, and the charging plate includes charging needle. When the connecting rod assembly drives the charging plate to move in the second direction, the charging needle extends into the inside of support in the second direction and charges the charged object. The second direction is perpendicular to the first direction and the first axis. The inside space surrounded by shell is used for containing support and charging device. The charging rack includes the support of storing charged object and the charging device arranged in the limited space outside the support, and can charge the charged object.
[0020] In another exemplary embodiment of the charging rack, the support has a slot for storing the charged object. The slot is open on one side in a direction opposite to the first direction to form an opening. The opening is used to put the charged object into or take out of the slot. Thus, the charged object is easily placed, and the shaking is reduced.
[0021] The utility model also provides a mobile X-ray machine, including X ray generating device, X ray receiving device and above charging rack. X ray generating device is used to produce X ray. X ray receiving device is used to receive X ray and generates X ray image. Charging rack is used for charging X ray receiving device. The mobile X-ray machine including above charging rack can charge the X-ray receiving device in the charging rack. BRIEF DESCRIPTION OF DRAWINGS

[0068] In order to have a clearer understanding of the technical features, objectives and effects of the utility model, the specific implementation manners of the utility model will be described with reference to the drawings, and the same reference numerals in the drawings represent the same or similar structures with the same function.
[0069] In this document, "illustrative" means "serving as an example, instance or illustration" and should not be necessarily construed as a preferred or advantageous implementation.
[0070] In the present text, "first", "second", "third" do not indicate their importance or order, etc., but are only used to distinguish each other for the description of the file.
[0071] For the sake of simplicity of the drawings, only the parts related to the present application are shown in the drawings, which do not represent the actual structure of the product.
[0072] Figure 1 For the structure schematic diagram for illustrating an exemplary embodiment of the charging device. Figure 2 For the schematic diagram for illustrating the positional relationship of each structure when the base plate is in the first position and the second position. See Figure 1 and Figure 2 In the exemplary embodiment, the charging device 100 charges the charged object 400, which includes a base plate 10, a linkage assembly 20, and a charging plate 30. The charged object 400 is, for example, an X-ray receiving device of a mobile DR, such as a flat panel detector, but is not limited thereto, and the charged object 400 can be other devices that need to be charged.
[0073] The base plate 10 is movably connected to the bracket 200 along the first direction D1 and the opposite direction thereof. As Figure 1 shown, the base plate 10 is, for example, provided with four third long holes 13 (only one of which is shown schematically) extending along the first direction D1. The bracket 200 is, for example, provided with four fixing blocks 230 (only one of which is shown schematically). Each fixing block 230 is, for example, inserted into one of the third long holes 13, so that the base plate 10 can move relative to the bracket 200 along the first direction D1 and the opposite direction thereof. In other exemplary embodiments, the number of fixing blocks 230 and third long holes 13 can be other numbers, and other ways of connecting the base plate 10 and the bracket 200 can also be selected. Figure 1 Figure 1 The linkage assembly 20 includes a first linkage 21, a second linkage 22, and a connecting shaft 23. The first linkage 21 and the second linkage 22 are rotatably sleeved on the connecting shaft 23 about a second axis X2 to form a scissors structure. A first end of the first linkage 21 is rotatably connected to the bracket 200 about a first axis X1, which is perpendicular to the first direction and parallel to the second axis X2. A second end (the upper end of the first linkage 21 in
[0074] The first end of the first linkage 21 is rotatably connected to the bracket 200 about a first axis X1, which is perpendicular to the first direction and parallel to the second axis X2. The second end (the upper end of the first linkage 21 in Figure 2 shown, the charging plate 30 is, for example, provided with a first long hole 31. The second end (the upper end of the first linkage 21 in Figure 2 Figure 2 the first long hole 31 and can move in the first long hole 31 along the first direction D1 and the opposite direction thereof.
[0075] The first end of the second link 22 ( Figure 2 The upper end of the second link 22 is movably connected to the bracket 200 along the first direction D1 and its opposite direction. The second end of the second link 22 is rotatably connected to the charging plate 30 about a third axis X3, which is parallel to the first axis X1. Figure 2 As shown, the bracket 200, for example, has a second elongated hole 220. The first end of the second connecting rod 22 ( Figure 2 The upper end of the second link 22 is inserted into the second elongated hole 220 and can move in the second elongated hole 220 along the first direction D1 and its opposite direction.
[0076] It should be noted that the second end of the first link 21 ( Figure 2 The upper end of the first link 21 is movably connected to the charging plate 30, which does not mean that the second end of the first link 21 ( Figure 2 The upper end of the first link 21 and the charging plate 30 only have linear motion along the first direction D1 and its opposite direction. In fact, the second end of the first link 21 ( Figure 2 The upper end of the first link 21 also rotates relative to the charging plate 30, due to the rotation of the first link 21 as a whole around the second axis X2. The first end of the second link 22 ( Figure 1 The same applies to the second link 22 (located at the upper end) which is movably connected to the bracket 200, so it will not be described in detail here.
[0077] The base plate 10, for example, has two first abutment surfaces 11. Figure 1 Only one of them is marked schematically in the text) and two second approach surfaces 12 ( Figure 1 Only one is schematically shown in the diagram. In the illustrative embodiment, the base plate 10 includes two pads 16 ( Figure 2 (Only one is schematically shown in the diagram), each pad 16 has a first abutment surface 11 and a second abutment surface 12. When the base plate 10 moves to the first position and the second position, the connecting shaft 23 abuts against the first abutment surface 11 (as shown in the diagram). Figure 2 (as shown in A) and the second abutment surface 12 (as shown in A) Figure 2 (As shown in Figure B). However, this is not the only embodiment. In other illustrative embodiments, the pad 16 can be replaced by other structures. The number of pads 16 can also be only one, and the connecting shaft 23 can abut against the pad 16 at one end and be movably connected to the base plate 10 in other ways at the other end.
[0078] When the base plate 10 is in the first position, the connecting shaft 23 abuts against the first abutting surface 11, such as Figure 2As shown in Figure A, at this time, the second end of the first link 21 and the first end of the second link 22 ( Figure 2 The upper ends of each connecting rod are located at the upper ends of the first long hole 31 and the second long hole 220, respectively.
[0079] When the base plate 10 moves from the first position to the second position, the connecting shaft 23 abuts against the second abutment surface 12, such as Figure 2 As shown in Figure B, at this time, the second end of the first link 21 and the first end of the second link 22 ( Figure 2 The upper ends of each connecting rod are respectively located at the lower ends of the first elongated hole 31 and the second elongated hole 220. The included angle of the scissor fork structure (the acute angle between the first connecting rod 21 and the second connecting rod 22) is compared to Figure 2 As the included angle shown in Figure A increases, the distance between the second axis X2 and the first axis X1 along the second direction D2 (the second direction D2 is perpendicular to the first direction D1 and the first axis X1) increases. The scissor fork structure drives the charging plate 30 to move along the second direction D2 to contact the object being charged 400. Figure 3 (Not shown in the drawing).
[0080] By incorporating a scissor-fork structure, when the base plate moves in a first direction, the scissor-fork structure drives the charging plate to move and contact the object being charged. This charging device can be installed within a limited space to charge the object.
[0081] Figure 2 This is a schematic diagram illustrating the structure of the linkage assembly. See also... Figure 3 and Figure 2 In the illustrative embodiment, the linkage assembly 20 further includes a first spring 24. One end of the first spring 24 is connected to the bracket 200, and the other end is connected to the first end of the second linkage 22. Figure 4 The upper end of the second link 22 is used to apply a force along the first direction D1 to the first end of the second link 22. Due to the presence of the first spring 24, the scissor fork structure tends to increase the angle between the first link 21 and the second link 22. Simultaneously, due to the force transmission of the second link 22, the connecting shaft 23 is closer to the first abutment surface 11 or the second abutment surface 12 compared to the case without the first spring 24. This facilitates increasing the abutment force of the connecting shaft on the first and second abutment surfaces, thereby improving the stability of the charging device.
[0082] Figure 5 and Figure 4 This is a schematic diagram illustrating another illustrative embodiment of the charging device. See also... Figure 5 and Figure 5In the illustrative embodiment, the linkage assembly 20 includes two first linkages 21 and two second linkages 22 to form two parallelly arranged scissor fork structures. The linkage assembly 20 further includes two first springs 24. This facilitates the stability of the charging device.
[0083] The base plate 10 further includes two supporting portions 14 extending along the second direction D2 to support the charged object 400. Each supporting portion 14 is arranged at the front end of the base plate 10 along the first direction D1. In other illustrative embodiments, the number of the supporting portions 14 can also be designed as one or more than two according to actual use requirements. The charging plate 30 includes two charging needles 32, for example, each of which extends towards the charged object 400 placed on the supporting portion 14 along the second direction D2 (not shown in the figure). The charged object 400 is electrically connected with the charging plate 30 through the charging needles 32. By placing the charged object 400 on the supporting portion 14, the base plate 10 moves along the first direction D1 under the gravity of the charged object 400, and the charging needle 32 on the charging plate 30 contacts the charged object 400 to charge under the driving of the linkage assembly 20. The whole process does not require additional actions of the charging device. Figure 6
[0084] The charging device 100 further includes two second springs 40. One end of each second spring 40 is connected to the base plate 10, and the other end is connected to the support 200 to apply a force along the opposite direction of the first direction D1 to the base plate 10. In this way, after the charged object leaves the base plate, the base plate returns to the first position under the elastic restoring force of the second spring 40 to facilitate the next charging. In other illustrative embodiments, the number of the second springs 40 can also be designed as one or more than two according to actual use requirements.
[0085] The charging device 100 further includes a bumper 50. The bumper 50 is fixedly arranged on the support 200. The base plate 10 further includes a buffering portion 15 extending along the opposite direction of the second direction D2. When the base plate 10 moves along the first direction D1 to the buffering portion 15 abutting against the bumper 50, the bumper 50 can be compressed under the abutting pressure of the buffering portion 15, and the elastic restoring force of the bumper 50 can slow down the movement speed of the base plate 10 along the first direction D1. In this way, the vibration caused by the rapid falling of the base plate can be buffered, and the buffering performance and stability of the charging device are improved.
[0086] The charging device 100 further includes a charging module 60 electrically connected with the charging plate 30. The charging module 60 includes a switch 61 arranged on the support 200. The switch 61 is a micro switch. The micro switch is a switch well known to those skilled in the art, which has a switch body 611, a roller 613, a spring sheet 612 and a contact 614. The structure of the micro switch is as shown in the figure. Figure 4 As shown, when the base plate 10 moves to abut against the roller 613, the base plate 10 pushes the roller 613 along a third direction D3 perpendicular to the first direction D1 and the second direction D2, causing the spring piece 612 to deform and push the contact 614 to move along the third direction D3, thereby closing the switch 61 to charge the object 400. This structure enables the charging device to automatically close the switch when the base plate descends along the first direction to the switch, eliminating the need for manual closing of the switch by the operator and simplifying the charging operation.
[0087] In an illustrative embodiment, the charging module 60 also includes a battery that powers the charging plate 30. Figures 4 to 6 (Not shown in the diagram), the battery can be mounted on or outside the bracket 200. Switch 61 electrically connects the charging board 30 and the battery. However, the battery is not mandatory; in other illustrative embodiments, the charging module does not include a battery, and instead, switch 61 is connected to a power strip for power.
[0088] See Figure 6 In the illustrative embodiment, the charging device 100 further includes two presence detection modules 70 for detecting whether the object to be charged 400 is placed in the bracket 200. The two presence detection modules 70 are disposed on the bracket 200 and arranged on both sides of the base plate 10. The presence detection module 70 is a microswitch, and its structure is as described above. Figure 5 As shown, it includes a switch body, a roller, a spring, and a contact. The switch body is mounted on a bracket 200, and the roller and spring extend through a through-hole in the bracket 200 to the other side of the bracket 200. Figure 5 As shown. When the charged object is 400 ( Figure 7 (Not shown in the diagram) After the bracket 200 is placed on the other side of the bracket 200, the object being charged 400 moves to the position of the roller of the presence detection module 70 under its own weight. The object being charged 400 pushes the roller of the presence detection module 70 in the opposite direction of the second direction D2, causing the spring of the presence detection module 70 to deform and push the contact of the presence detection module 70 to move in the opposite direction of the second direction D2, so as to close the presence detection module 70. The object being charged 400 continues to move in the first direction D1 and is finally supported by the support part 14. Then the base plate 10 moves from the first position to the second position in the first direction D1.
[0089] Two in-place detection modules 70 are connected in series to an external circuit comprising a processor. If both in-place detection modules 70 are closed, the external circuit is closed, and the processor can receive a normal detection signal sent by the in-place detection modules 70. If at least one of the two in-place detection modules 70 is not closed, the external circuit is not closed, and the processor can receive an abnormal detection signal sent by the in-place detection modules 70. After receiving the detection signal, the operator checks whether the charged object 400 is placed in the support 200 or troubleshoots the in-place detection modules 70. In other illustrative embodiments, the number of in-place detection modules 70 can be one or more than two. The in-place detection modules 70 can also be sensors. By providing in-place detection modules, the operator can easily check whether the charged object is placed in the support.
[0090] It should be noted that in the illustrative embodiment, when at least one of the two in-place detection modules 70 is not closed, the processor can receive an abnormal detection signal, but this does not affect the normal operation of the charging module 60. After the switch 61 is closed, a normal feedback signal is sent to the processor and the charging plate 30 is charged. If the switch 61 is not closed, an abnormal feedback signal is sent, and the processor receives the abnormal feedback signal. The operator can troubleshoot the fault according to the abnormal feedback signal.
[0091] In the illustrative embodiment, if the charging device is working normally, the charging process includes: when the charged object is placed in the support, the charged object moves in the first direction under the action of gravity, and the charged object abuts against the rollers of the two in-place detection modules during movement, so that the two in-place detection modules are closed and send a normal detection signal to the processor. The charged object then reaches the support portion, and at this time, the bottom plate is located at the first position. The charged object drives the bottom plate to move in the first direction from the first position to the second position. At the second position, the two scissor fork structures push the charging plate in the second direction towards the charged object, and the bottom plate slows down to the position of the switch under the action of the buffer and abuts against the rollers, so that the switch is closed to supply power to the charging plate, the charging plate charges the charged object, and the switch sends a normal feedback signal to the processor.
[0092] If the processor receives an abnormal feedback signal, the operator needs to check the charging module. If the processor receives an abnormal detection signal, the operator needs to check whether the charged object is placed in the support and whether the in-place detection modules are normal.
[0093] Figure 1 The structure diagram of one illustrative embodiment of the charging rack. Referring to Figure 5 , Figure 7 and In the illustrative embodiment, the charging rack comprises a support 200, the charging device 100 described above, and a housing 300. The interior of the support 200 is provided with a slot 210 for storing the object to be charged 400. The slot 210 is open on the side opposite to the first direction D1 to form an opening. The opening is used to put the object to be charged 400 into or take it out of the slot 210. In this way, the object to be charged is placed conveniently and the shaking is reduced. In other illustrative embodiments, the interior of the support 200 can also be provided with other structures to store the object to be charged 400.
[0094] The charging device 100 is arranged outside the support 200, and the charging plate 30 comprises charging pins 32, for example, but is not limited thereto. In other illustrative embodiments, the charging pins 32 can also be replaced by other structures. When the linkage assembly 20 drives the charging plate 30 to move along the second direction D2, the charging pins 32 extend into the interior of the support 200 along the second direction D2 to charge the object to be charged 400. The interior space enclosed by the housing 300 is used to accommodate the support 200 and the charging device 100.
[0095] It is worth noting that the charging rack is also provided with a slot 240, although the interior of the slot 240 can also store the object to be charged 400, but the object to be charged 400 cannot be charged in the slot 240.
