Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a charging structure and a DR system. Background Art

[0002] DR system usually refers to a digital radiography system that uses direct image conversion technology of flat-panel detectors. As the core component of the DR system, the flat-panel detector plays a decisive role in the image quality. Based on the different power supply methods, it can be divided into wired-powered flat-panel detectors and wireless-powered flat-panel detectors (i.e., flat-panel detectors with batteries). Since flat-panel detectors need to be moved frequently during use, wired-powered flat-panel detectors have many inconveniences in use due to the length of the wires and the limitation of movement. Therefore, most of the current DR systems use wireless-powered flat-panel detectors.

[0003] At present, the charging connector of the wireless power flat panel detector in the prior art is usually fixed on the bottom plate of the cavity for accommodating the flat panel detector. When charging, the flat panel detector is inserted into the cavity, so that the charging connector is inserted into the charging interface of the flat panel detector, thereby achieving the purpose of charging the flat panel detector. However, during use, since the charging head is fixed, it is very easy to damage the charging head due to excessive impact when inserting the flat panel detector. Summary of the invention

[0004] In view of the defects in the prior art, the purpose of the present invention is to provide a charging structure and a DR system to solve or alleviate the above-mentioned technical problems existing in the prior art.

[0005] In order to achieve the above object, on the one hand, the present invention provides a charging structure for charging a flat panel detector, which is arranged on a rack, and the rack is provided with a receiving cavity for receiving the flat panel detector, comprising:

[0006] a charging connector, which is arranged on the rear side of the rear side wall of the accommodating cavity, and the rear side wall of the accommodating cavity is provided with a first through hole for allowing a charging electrode of the charging connector to pass through; and

[0007] A control component is arranged on the frame. In a non-working state, the charging electrode of the charging connector retracts into the first through hole. In a working state, the flat panel detector is pushed into the accommodating cavity, and force is applied to the control component to drive the charging connector to move toward the front side of the accommodating cavity, so that the charging electrode of the charging connector passes through the first through hole.

[0008] Furthermore, it also includes:

[0009] a carrying plate, which is arranged in the accommodating cavity in a drawer structure; and

[0010] A fixing assembly, which is disposed on the carrying plate and is used to detachably fix the flat panel detector on the carrying plate;

[0011] Wherein, in a working state, the flat panel detector is fixed on the supporting plate by the fixing assembly, and the flat panel detector is inserted into the accommodating cavity by pushing the supporting plate into the accommodating cavity, and in a non-working state, the flat panel detector is pulled out of the accommodating cavity by pulling the supporting plate out of the accommodating cavity.

[0012] Furthermore, the control component comprises:

[0013] A control rod, which is U-shaped, with a middle portion hinged to the frame, a first end connected to the charging connector, and a second end extending into the accommodating cavity; and

[0014] A first elastic member, a first end of which is connected to the charging connector, a second end of which is connected to the frame, and in a natural state, has a tendency to move the charging connector away from the accommodating cavity;

[0015] Wherein, in a working state, by pushing the flat-panel detector into the accommodating cavity, the flat-panel detector or the carrying plate applies force to the control rod to drive the charging connector to move toward the front side of the accommodating cavity, so that the charging electrode of the charging connector passes through the first through hole; in a non-working state, the charging connector is driven to move toward the rear side of the accommodating cavity by the first elastic member, so that the charging electrode of the charging connector retracts into the first through hole.

[0016] Furthermore, the control component comprises:

[0017] A slider, which is arranged at one side of the accommodating cavity, is slidably connected to the frame, and is provided with a control arm;

[0018] A second elastic member, a first end of which is connected to the slider, a second end of which is connected to the frame, and in a natural state, has a tendency to move the slider toward the front side of the accommodating cavity;

[0019] a third elastic member, a first end of which is connected to the charging connector and a second end of which is connected to the frame, and in a natural state, has a tendency to move the charging connector toward the front side of the accommodating cavity; and

[0020] A pull rope, a first end of which is fixedly connected to the slider and a second end of which is fixedly connected to the charging connector;

[0021] Wherein, in the working state, by pushing the flat-panel detector into the accommodating cavity, the flat-panel detector or the supporting plate applies force to the control arm to drive the slider to move toward the rear side of the accommodating cavity, thereby driving the charging connector to move toward the accommodating cavity through the elastic force of the third elastic member, so that the charging electrode of the charging connector passes through the first through hole; in the non-working state, the slider is moved toward the front side of the accommodating cavity through the elastic force of the second elastic member, thereby driving the charging connector to move toward the rear side of the accommodating cavity through the pull rope, so that the charging electrode of the charging connector is retracted into the first through hole.

[0022] On the other hand, the present invention provides a DR system, comprising any one of the charging structures described above.

[0023] Beneficial effects of the present invention:

[0024] The charging structure and DR system provided by the present invention have a simple structure and a reasonable design. By setting a control component, the charging electrode of the charging connector is hidden in the first through hole when not in operation, and moves outside the first through hole when in operation, thereby achieving the purpose of avoiding damage to the charging electrode of the charging connector due to excessive impact force.

[0045] In one embodiment, Figure 1-11 As shown, the present invention provides a charging structure for charging a flat panel detector, which is arranged on a rack 100. It should be noted that the rack 100 may be a rack 100 of a DR system or an additional rack 100. The rack 100 has a receiving cavity 110 for receiving the flat panel detector.

[0046] The charging structure includes a charging connector 200 and a control component.

[0047] The charging connector 200 is disposed on the rear side of the rear side wall of the accommodating cavity 110 , and the rear side wall of the accommodating cavity 110 is provided with a first through hole 120 for the charging electrode of the charging connector 200 to pass through.

[0048] The control component is disposed on the frame 100 , and is used to control the movement of the charging connector 200 so that the charging electrode of the charging connector 200 passes through the first through hole 120 or retracts into the first through hole 120 .

[0049] Specifically, in the non-working state, the charging electrode of the charging connector 200 retracts into the first through hole 120 to hide the charging electrode of the charging connector 200 in the rear side plate of the accommodating cavity 110, thereby achieving the purpose of avoiding damage to the charging connector 200 due to excessive impact force.

[0050] In the working state, the flat panel detector is pushed into the accommodating cavity 110, and force is applied to the control component to drive the charging connector 200 to move toward the front side of the accommodating cavity 110, so that the charging electrode of the charging connector 200 passes through the first through hole 120, thereby achieving the purpose of charging.

[0051] like Figure 1 , 3 As shown in FIGS. 6 and 9 , in one embodiment, a carrier plate 300 is disposed on the frame 100 , and the carrier plate 300 is disposed in a drawer structure in the accommodating cavity 110 . A fixing assembly is disposed on the carrier plate 300 , and the fixing assembly is used to detachably fix the flat panel detector on the carrier plate 300 .

[0052] In the working state, the flat panel detector is fixed on the supporting plate 300 by a fixing assembly, and the supporting plate 300 is pushed into the accommodating cavity 110 to insert the flat panel detector into the accommodating cavity 110. In the non-working state, the supporting plate 300 is pulled out of the accommodating cavity 110 to pull the flat panel detector out of the accommodating cavity 110.

[0053] In this embodiment, the flat-panel detector is detachably fixed on the carrier plate 300 by a fixing assembly, so that the flat-panel detector can be inserted into or pulled out of the accommodating cavity 110 by pushing and pulling the carrier plate 300. The structure is simple and the operation is convenient, so that the flat-panel detector can be easily taken in and out, and further the flat-panel detector can be easily charged.

[0054] Specifically, the fixing assembly includes a placement groove 310 formed on the top of the carrier plate 300 and adapted to the flat panel detector.

[0055] like Figure 1-4 As shown, in one embodiment, the control assembly includes a control rod 410 and a first elastic member 420 .

[0056] The control rod 410 is U-shaped, the middle part of the control rod 410 is hinged to the frame 100, and the first end of the control rod 410 is connected to the charging connector 200. In this embodiment, the first end of the control rod 410 abuts against the charging connector 200. The second end of the control rod 410 extends into the accommodating cavity 110, so that when the flat panel detector or the carrier plate 300 is pushed into the accommodating cavity 110, the flat panel detector or the carrier plate 300 can abut against the control rod 410, thereby driving the charging connector 200 to move through the control rod 410.

[0057] The first end of the first elastic member 420 is connected to the charging connector 200, and the second end is connected to the frame 100. In a natural state, the first elastic member 420 has a tendency to move the charging connector 200 away from the accommodating chamber 110, that is, the first elastic member 420 is used to provide power for the charging connector 200 to move away from the accommodating chamber 110. Specifically, the first elastic member 420 can be any component that can provide elastic force, such as a metal spring, a rubber spring, an elastic rope, a rubber band, etc. Preferably, in this embodiment, the first elastic member 420 is a spring.

[0058] In the working state, by pushing the flat panel detector into the accommodating cavity 110, the flat panel detector or the carrier plate 300 applies force to the control rod 410 to drive the charging connector 200 to move toward the front side of the accommodating cavity 110, so that the charging electrode of the charging connector 200 passes through the first through hole 120, so as to achieve the purpose of charging the flat panel detector. In the non-working state, the charging connector 200 is driven to move toward the rear side of the accommodating cavity 110 by the first elastic member 420, so that the charging electrode of the charging connector 200 retracts into the first through hole 120, so as to achieve the purpose of hiding the charging electrode of the charging connector 200 outside the accommodating cavity 110, and further achieve the purpose of preventing the charging electrode of the charging connector 200 from being damaged due to excessive impact force.

[0059] Preferably, if Figure 5 As shown, the control rod 410 includes a first rod body 411, a second rod body 412 and a fifth elastic member 413 that is fully elastic. The first end of the first rod body 411 is connected to the charging connector 200, and the second end is connected to the first end of the second rod body 412 through the fifth elastic member 413, and the second end of the second rod body 412 extends into the accommodating cavity 110. A force is applied to the second end of the first rod body 411 through the charging connector 200 to make the fifth elastic member 413 fully elastic, thereby bending the control rod. Specifically, the fifth elastic member 413 is a spring or a bendable rubber rod. In this embodiment, the fifth elastic member 413 is a rubber rod.

[0060] When the impact force is too large, the charging connector 200 can push the fifth elastic member 413 to bend, thereby further preventing the charging electrode of the charging connector 200 from being damaged due to the excessive impact force.

[0061] Preferably, the second end of the control rod 410 is a retractable elastic structure, for example, an elastic retractable rod structure. The charging connector 200 applies a force to the second end of the control rod 410 to retract the second end of the control rod 410 .

[0062] When the impact force is too large, the charging connector 200 can push the second end of the control rod 410 to contract, thereby further preventing the charging electrode of the charging connector 200 from being damaged due to the excessive impact force.

[0063] like Figure 6-11 As shown, in one embodiment, the control assembly includes a slider 430 , a second elastic member 440 , a third elastic member 450 and a pull rope 460 .

[0064] The slider 430 is disposed at one side of the accommodating cavity 110 , and the slider 430 is slidably connected to the frame 100 . The slider 430 is provided with a control arm 431 , one end of which extends toward the accommodating cavity 110 .

[0065] The first end of the second elastic member 440 is connected to the slider 430, and the second end is connected to the frame 100. In the natural state, the second elastic member 440 has a tendency to move the slider 430 toward the front side of the accommodating chamber 110, that is, the first elastic member 420 is used to provide power to drive the slider 430 to move toward the front side of the accommodating chamber 110.

[0066] The first end of the third elastic member 450 is connected to the charging connector 200, and the second end is connected to the frame 100. In a natural state, the third elastic member 450 has a tendency to move the charging connector 200 toward the front side of the accommodating cavity 110, that is, the third elastic member 450 is used to provide power to drive the charging connector 200 to move toward the front side of the accommodating cavity 110.

[0067] Specifically, the second elastic member 440 and the third elastic member 450 can be any component that can provide elastic force, such as a metal spring, a rubber spring, an elastic rope, a rubber band, etc. Preferably, in this embodiment, the second elastic member 440 and the third elastic member 450 are springs.

[0068] The first end of the pull rope 460 is fixedly connected to the slider 430, and the second end is fixedly connected to the charging connector 200. Thus, in a natural state, the second elastic member 440 places the slider 430 in an initial position, and the slider 430 places the charging connector 200 in an initial position (i.e., the charging electrode of the charging connector 200 is hidden in the first through hole 120) through the pull rope 460.

[0069] Among them, in the working state, by pushing the flat-panel detector into the accommodating cavity 110, the flat-panel detector or the supporting plate 300 applies force to the control arm 431 to drive the slider 430 to move toward the rear side of the accommodating cavity 110. Since the length of the pull rope 460 remains unchanged, the charging connector 200 loses the pulling force of the pull rope 460. Therefore, under the action of the elastic force of the third elastic member 450, the charging connector 200 is driven by the elastic force of the third elastic member 450 to move toward the direction close to the accommodating cavity 110, so that the charging electrode of the charging connector 200 passes through the first through hole 120. In the non-working state, the slider 430 is moved toward the front side of the accommodating cavity 110 by the elastic force of the second elastic member 440, so that the charging connector 200 is driven to move toward the rear side of the accommodating cavity 110 by the pull rope 460, so that the charging electrode of the charging connector 200 retracts into the first through hole 120.

[0070] When in use, in a non-working state, under the action of the elastic force of the second elastic member 440 , the second elastic member 440 places the slider 430 in an initial position, and the slider 430 places the charging connector 200 in the initial position through the pull rope 460 .

[0071] In the working state, when the flat panel detector is pushed into the placement slot 310, the flat panel detector or the carrier plate 300 applies force to the control arm 431, thereby driving the slider 430 to move, so that the pull rope 460 loses the pulling force on the charging connector 200, and under the action of the elastic force of the third elastic member 450, the charging connector 200 is driven to move, thereby achieving the purpose of making the charging electrode of the charging connector 200 pass through the first through hole 120.

[0072] The control assembly provided in this embodiment has a simple structure and a reasonable design. It can not only hide the charging connector 200 in a non-working state, thereby preventing the charging electrode of the charging connector 200 from being damaged due to excessive impact force when inserted into the flat-panel detector, but also when the impact force is too large, the flat-panel detector can also push the charging connector 200 to overcome the elastic force of the third elastic member 450 to move, and then under the elastic force of the third elastic member 450, the charging electrode of the charging connector 200 is slowly inserted into the flat-panel detector, thereby achieving the purpose of further improving the effect of preventing the charging electrode of the charging connector 200 from being damaged due to excessive impact force.

[0073] Preferably, if Figure 8 , 11As shown, a groove 320 is provided on the side of the carrier plate 300 facing the slider 430 so that the carrier plate 300 will not interfere with the control arm 431. A driving block 470 is provided on the bottom side wall of the groove 320. In the working state, the flat panel detector applies force to the driving block 470 so that the driving block 470 extends into the groove 320 to apply force to the control arm 431, thereby achieving the purpose of driving the slider 430 to move, and further achieving the purpose of making the charging electrode of the charging connector 200 pass through the first through hole 120. In the non-working state, the driving block 470 retracts outside the groove 320 so that the driving block 470 cannot apply force to the control arm 431, thereby achieving the purpose of being unable to drive the slider 430 to move, and further achieving the purpose of being unable to make the charging electrode of the charging connector 200 pass through the first through hole 120.

[0074] The control component provided in this embodiment will drive the charging electrode of the charging connector 200 to pass through the first through hole 120 only when in the working state, thereby achieving the purpose of increasing its service life.

[0075] Specifically, a driving arm 471 is provided on the side of the driving block 470 facing the placement groove 310. In the non-working state, the driving arm 471 extends into the placement groove 310 so that the flat-panel detector can apply force to the driving arm 471 to drive the driving block 470 to move. In the working state, the flat-panel detector applies force to the driving arm 471 to drive the driving block 470 to move, so that the driving block 470 extends into the groove 320.

[0076] The driving block 470 is slidably connected to the supporting plate 300, and a fourth elastic member 480 is arranged between the driving block 470 and the supporting plate 300. Both ends of the fourth elastic member 480 are respectively connected to the driving block 470 and the supporting plate 300, and in a natural state, the fourth elastic member 480 has a tendency to make the driving block 470 move in a direction away from the groove 320, that is, the fourth elastic member 480 is used to provide power to drive the driving block 470 to move in a direction away from the groove 320.

[0077] Specifically, the fourth elastic member 480 can be any component that can provide elastic force, such as a metal spring, a rubber spring, an elastic rope, a rubber band, etc. Preferably, in this embodiment, the fourth elastic member 480 is a spring.

[0078] Specifically, when in use, in a non-working state, that is, when the flat-panel detector is not placed in the placement slot 310, under the action of the elastic force of the fourth elastic member 480, the driving block 470 retracts to the bottom side wall of the groove 320, so that when the driving block 470 pushes and pulls the supporting plate 300, the driving block 470 cannot apply force to the control arm 431, thereby failing to drive the slider 430 to move.

[0079] In the working state, that is, when the flat panel detector is placed in the placement groove 310, in the process of placing the flat panel detector in the placement groove 310, the flat panel detector applies force to the driving arm 471, so that the driving block 470 overcomes the elastic force of the fourth elastic member 480 and moves, and then the driving block 470 extends into the groove 320, so that in the process of pushing and pulling the carrier plate 300, the driving block 470 can apply force to the control arm 431, thereby achieving the purpose of driving the slider 430 to move.

[0080] In one embodiment, the present invention further provides a DR system, comprising the charging structure described in any of the above embodiments.

However, it is understood that embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.

The charging structure according to claim 2, characterized in that: The control component comprises: A slider (430) is arranged on one side of the accommodating cavity (110), is slidably connected to the frame (100), and is provided with a control arm (431); A second elastic member (440), a first end of which is connected to the slider (430) and a second end of which is connected to the frame (100), and in a natural state, has a tendency to move the slider (430) toward the front side of the accommodating chamber (110); a third elastic member (450), a first end of which is connected to the charging connector (200) and a second end of which is connected to the frame (100), and in a natural state, has a tendency to move the charging connector (200) toward the front side of the accommodating cavity (110); and a pull rope (460), a first end of which is fixedly connected to the slider (430) and a second end of which is fixedly connected to the charging connector (200); Wherein, in a working state, by pushing the flat panel detector into the accommodating cavity (110), the flat panel detector or the carrying plate (300) applies force to the control arm (431) to drive the slider (430) to move toward the rear side of the accommodating cavity (110), thereby driving the charging connector (200) to move in a direction close to the accommodating cavity (110) through the elastic force of the third elastic member (450), so that the charging electrode of the charging connector (200) passes through the first through hole (120); in a non-working state, the slider (430) is moved toward the front side of the accommodating cavity (110) through the elastic force of the second elastic member (440), thereby driving the charging connector (200) to move toward the rear side of the accommodating cavity (110) through the pull rope (460), so that the charging electrode of the charging connector (200) retracts into the first through hole (120).

5. A DR system, characterized in that: The charging structure comprises the charging structure described in any one of claims 1 to 4.
