[0010] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present utility model.

[0011] Figure 1 A power box 100 of a flat panel detector according to the present utility model is shown. The power box 100 is configured to be connectable to a flat panel detector. The flat panel detector is, for example, an imaging panel or a detecting panel in the field of medical equipment, which can be, for example, a Medium Voltage Panel (MV Panel). The flat panel detector works by being connected to power. The flat panel detector usually needs different levels of direct current voltage, such as 5V, 12V, 24V, etc., to power its internal circuits, etc. In order to provide power to the flat panel detector, the power box 100 of the flat panel detector is provided, which obtains electrical energy from an external power supply (usually an alternating current power supply) or other specified power input source, and then outputs direct current voltage and current that meet the requirements of each part of the flat panel detector for power supply to the flat panel detector after internal conversion, regulation, etc.

[0012] As shown in Figure 1 The power box 100 of the flat panel detector includes a housing 120, an input interface 140, an output interface 160, and a circuit portion (not shown) contained in the housing 120. The input interface 140 is provided on the housing 120 and is configured to receive the input of power. For example, the input interface 140 is used to connect an external power supply. The circuit portion contained in the housing 120 is configured to convert the power input via the input interface 140 into power capable of driving the flat panel detector, for example, including one or more of a rectifier circuit, a transformer, a voltage conversion circuit, a voltage stabilizing circuit, a filter circuit, and a protection circuit. The output interface is provided on the housing 120 and is configured to connect the flat panel detector and output the converted power to the flat panel detector.

[0013] The housing 120 is formed in a columnar shape including a bottom surface and a side surface, for example, a cuboid shape. In this case, the housing 120 includes two opposite bottom surfaces and a side surface connecting the two bottom surfaces. Figure 2 The power supply box 100 is a flat panel detector. Figure 1 FIG. 2 is a front view of the power supply box 100 viewed from the direction A in FIG. 1, showing one of the bottom surfaces of the housing 120 of the power supply box 100. In this example, the input interface 140 and the output interface 160 are provided on the bottom surface, and the bottom surface of the housing 120 is further provided with a grounding pin 170 for grounding, an indicator lamp 180 for indicating the working state of the power supply box 100, and a switch 190 for starting or stopping the power supply box 100. Figure 2 The positions and configurations of the components shown in FIG. 2 are only illustrative, and those skilled in the art can make appropriate adjustments without affecting the function of the power supply box 100.

[0014] The housing 120 is provided with one or more holes 150 for mounting a connecting member and being conductive. Referring to FIG. 3, Figure 3 The holes 150 can include holes 150-1 for mounting a connecting member to connect the outside of the power supply box 100 and holes 150-2 for mounting a connecting member to fix components of the power supply box 100 itself. The connecting member is, for example, a screw, a bolt, etc., which is connected to other components via the holes 150. For example, the connecting member connects the power supply box 100 with components outside the power supply box 100 via the holes 150-1, thereby stably mounting the power supply box 100 at a specific mounting position. On the other hand, the connecting member assembles or fixes the housing 120 of the power supply box 100 via the holes 150-2, and / or fixes the circuit part, electronic components, etc. inside the power supply box 100. The one or more holes 150 are conductive and can serve as reliable grounding connection points, ensuring safe grounding. When abnormal conditions such as leakage, static electricity accumulation, etc. occur in the internal circuit of the power supply box 100, the current can be smoothly conducted to the ground through the one or more conductive holes 150, avoiding electrification of the housing 120 of the power supply box 100, preventing electric shock of the operator, and reducing damage of static electricity to the internal electronic components, ensuring the safe and stable operation of the power supply box 100 and the equipment such as the flat panel detector connected thereto.

[0015] At least one side of the shell 120 has a plurality of first strip structures 122 and a plurality of second strip structures 124 extending along the length direction of the power box 100. The length direction of the power box 100 is, for example, the extension direction of the longest side of the shell 120 of the power box 100. The length of the first strip structures 122 and the second strip structures 124 can be substantially the same as the length of the longest side of the cuboid shell 120. The first strip structures 122 and the second strip structures 124 are protruding or recessed structures on the side of the shell 120, forming the outer surface of the non-flat side of the shell 120. Because the outer surface of the side of the shell is non-flat, the slip resistance and heat dissipation of the shell 120 of the power box 100 are increased.

[0016] For example, flat panel detectors and their power boxes 100 are usually used in complex medical environments, and the non-flat shell 120 can prevent the power box 100 from accidentally falling due to the excessively smooth outer surface of the power box 100. Thus, physical damage to the power box 100 is avoided, ensuring normal operation and reducing safety hazards caused by falling.

[0017] Specifically, the width of the first strip structure 122 is greater than the width of the second strip structure 124. The width of the first strip structure 122 or the second strip structure 124 refers to the dimension of the strip structure in the direction orthogonal to the extension direction of the first strip structure 122 or the second strip structure 124. Thus, the shell 120 of the power box 100 has at least two widths of strip structures, the wider first strip structure 122 is easier to be gripped by the user, making the power box 100 have better slip resistance, and preventing it from being easily cut or scratched by some sharp objects during use, such as avoiding surface damage such as cuts when in contact with other hard objects or subjected to accidental external forces. The narrower second strip structure 124 increases the surface area of the shell 120, and because of its small width, more second strip structures 124 can be arranged in a unit area compared to the first strip structure 122. In this way, the second strip structure 124 can be used as a heat dissipation fin of the power box 100, allowing the power box 100 to better dissipate the heat generated by the circuit portion contained in the shell 120, increasing the heat dissipation of the power box 100.

[0018] More specifically, at least one second strip structure 124 is arranged between two adjacent first strip structures 122, uniformly ensuring the heat dissipation of the power box 100 while taking into account the slip resistance of the power box 100.

[0019] In some embodiments, the shell 120 is made of metal or alloy, and the outer surface of the shell 120 is anodized. Anodizing refers to a process in which a metal or alloy is used as an anode and placed in an electrolyte, and an oxidation reaction occurs on the surface of the anode metal by applying a direct current, thereby generating an oxide film on the surface. That is, the outer surface of the shell 120 includes an oxide film generated by anodizing the outer surface. Preferably, all the outer surfaces of the shell 120 are anodized. The outer surface of the shell 120 that is anodized increases corrosion resistance and wear resistance. In the use environment of the flat panel detector machine power box, such as a medical institution or an industrial detection site, there are often some corrosive liquids or industrial waste gases. The shell 120 of the power box 100 that is anodized can better resist these corrosion factors. In addition, the anodized outer surface provides better adhesion for paint primer and glue than bare metal, facilitating processing during production of the power box 100, and preventing the power box 100 from detaching the label attached to the shell 120.

[0020] In some embodiments, one or more holes 150 are threaded holes, and the surface of the inner wall of the threaded hole is conductive treated. The threaded hole, also known as a tapped hole, is used to install threaded connectors such as bolts, screws, etc., to achieve fastening connection between components. In conventional technology, only the outer surface of the shell is usually treated, and the inner wall of the threaded hole cannot be well treated. The surface of the inner wall of the threaded hole of the present utility model is additionally conductive treated, which can increase the conductivity of the connecting surface, thereby ensuring grounding safety.

[0021] In some embodiments, the surface of the inner wall of the threaded hole is plated with a conductive metal layer. The electroplating process can form a uniform conductive layer on the surface of the complex shape (such as threads) of the inner wall of the threaded hole, ensuring good conductivity throughout the threaded hole.

[0022] In some embodiments, the surface of the inner wall of the threaded hole is coated with a conductive coating. The conductive coating is a coating containing conductive particles (such as metal powder, conductive carbon black, etc.). The surface of the inner wall of the threaded hole is conductive treated by coating the surface of the inner wall of the threaded hole with a conductive coating, which is simple to operate and has low cost.

[0023] In some embodiments, the first strip structure 122 is a raised ridge on the side of the shell 120, and the second strip structure 124 is a recessed groove on the side of the shell 120. The cross section of the raised ridge and the recessed groove is, for example, polygonal (such as rectangular) or arc-shaped. In the example shown in FIG. 1, the first strip structure 122 (raised ridge) is represented by the area shown in the shadow between the two thick solid lines on the side of the power box 100; the second strip structure 124 (recessed groove) is represented by thin solid lines, each of which represents a recessed groove. Figure 3 In some embodiments, the first strip structure 122 is a raised ridge on the side of the shell 120, and the second strip structure 124 is a recessed groove on the side of the shell 120. The cross section of the raised ridge and the recessed groove is, for example, polygonal (such as rectangular) or arc-shaped. In the example shown in FIG. 1, the first strip structure 122 (raised ridge) is represented by the area shown in the shadow between the two thick solid lines on the side of the power box 100; the second strip structure 124 (recessed groove) is represented by thin solid lines, each of which represents a recessed groove.Figure 3 The right side of the power box 100 shown in the middle includes three first strip structures 122 (raised ridges), and between two adjacent first strip structures 122, there are four second strip structures 124 (concave grooves).

[0024] In some embodiments, the width of the first strip structure 122 is 4 mm - 12 mm, and the raised height of the first strip structure 122 is 1 mm - 6 mm; the width of the second strip structure 124 is 1 mm - 3 mm, and the concave depth of the second strip structure 124 is 0.2 mm - 2 mm.

[0025] For example, the shell 120 of the power box 100 can have a cuboid structure, and the longest side thereof has a length of about 250 mm, for example, and the sides in the other two directions have lengths of about 80 mm - 150 mm, respectively. The power box has a certain weight and volume, and is not easy to carry. The first strip structure 122 can be provided with a width and a raised height suitable for the user to grasp. The second strip structure 124 can be provided with a width and a raised height suitable for significantly increasing the heat dissipation.

[0026] In some embodiments, in one power box 100, the widths and the raised heights of the plurality of first strip structures 122 can be different, and / or the widths and the raised heights of the plurality of second strip structures 124 can be different.

[0027] In some embodiments, the distance between two adjacent second strip structures 124 is less than the distance between two adjacent first strip structures 122. That is, the arrangement density of the second strip structures 124 on the shell 120 is greater than the arrangement density of the first strip structures 122 on the shell 120. Further, in one power box 100, the number of second strip structures 124 is greater than the number of first strip structures 122.

[0028] In some embodiments, the first strip structures 122 and the second strip structures 124 are uniformly distributed on the side of the shell 120, and each side of the shell 120 includes a plurality of first strip structures 122 and a plurality of second strip structures 124. In this way, the slip resistance and the heat dissipation of the power box 100 are further improved. It is easy to understand that uniform distribution means that the interval distances between all strip structures including the first strip structures 122 and the second strip structures 124 are substantially the same.

[0029] In some embodiments, the first strip structure 122 and the second strip structure 124 are integrally formed with the housing 120. For example, the housing 120 including the first strip structure 122 and the second strip structure 124 is formed by die casting. That is, the first strip structure 122 and the second strip structure 124 are integrally formed with the housing 120, reducing the number of parts.

[0030] In some embodiments, the power supply box 100 of the flat panel detector further includes a support bracket 110 for supporting the power supply box 100, the support bracket 110 having one or more holes 150 for mounting connectors and capable of conducting electricity as described above. Figure 4 Power supply box 100 for flat panel detector Figure 1 The side view viewed from direction B. Figure 4 In the example shown, the support bracket 110 consists of two strip-shaped brackets disposed on one side of the housing 120 of the power supply box 100. One or more holes 150-1 are formed on the support bracket 110. Connectors can install the support bracket 110, and thus the power supply box 100, to a specific mounting position via these holes 150-1. The one or more holes 150 on the support bracket 110 are also conductive, allowing current to be smoothly conducted to the mounting position and thus to ground, ensuring grounding safety. The support bracket 110 can be formed as part of the housing 120 or attached to the housing 120. By providing the support bracket 110, the power supply box 100 can be placed stably on a flat surface or installed in a specific mounting position, ensuring that the power supply box will not shake or shift during device operation, thus guaranteeing the installation reliability of the power supply box 100 of the flat panel detector.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
