[0025] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0026] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0027] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The embodiment of the present invention provides a hot-swappable converter module, such as Figure 1 As shown, Figure 1 The overall structural diagram of the hot-swappable converter module is shown in FIG. The height dimension of the hot-swappable converter module meets 3U, for example, the height is 130 mm, and the width can be set to 445 mm, that is, the hot-swappable converter module can be installed in a standard cabinet. Specifically, as Figure 1 As shown, the hot-swappable converter module includes: an upper casing 1, a lower casing 2, a fan panel 3, a mounting ear handle 4 and a fixed connector 5 for connecting the various components; wherein the fixed connector 5 can be a connector such as a fixing screw. The upper casing 1 and the lower casing 2 are snap-fitted and installed, and the fan panel 3 is installed on the same side surface of the upper casing 1 and the lower casing 2; the opposite side surface of the fan panel 3 is provided with ventilation holes. It can be understood that the upper casing 1 and the lower casing 2 are arranged opposite to each other on one side where components (such as a power supply electronic device unit) are installed, that is, the two parts of the casing are arranged relatively superimposed. The fan panel 3 is installed on the same side surface of the upper casing 1 and the lower casing 2, and the other side surface opposite to the fan panel 3 has a through hole ( Figure 1This perspective is not directly shown in the figure), and then after the equipment is assembled, when the fan in the fan panel 3 rotates, a heat dissipation airflow can be formed between the air outlet of the fan panel 3 and the ventilation holes on the side opposite to it, so as to dissipate heat for the hot-swappable converter module, that is, the wind blown by the fan in the fan panel 3 and the heat emitted by various components inside the upper casing 1 and the lower casing 2 are dissipated.

[0029] For example, after the upper housing 1, the lower housing 2 and the fan panel 3 are assembled, a closed air duct is formed inside the hot-swappable inverter module, and the air outlet of the fan faces the side of the upper and lower housings with mesh ventilation holes, thereby increasing the opening rate of the air outlet and reducing wind resistance, so that the air duct is unobstructed when the fan exhausts or blows air into the hot-swappable inverter module, forming air convection, which can prevent external dust from accumulating in the hot-swappable inverter module and reduce the influence of dust accumulation on the heat dissipation of components in the hot-swappable inverter module. The flowing airflow mainly brings out the heat of internal heat-generating components.

[0030] Furthermore, if Figure 2 As shown, Figure 2 The specific structural schematic diagram of the ear handle 4 is shown. The ear handle 4 includes a housing mounting plate 41, a cabinet mounting plate 42 and a handle portion 43; the ear handle 4 is a sheet metal part formed by stamping and bending. The housing mounting plate 41 mounts the ear handle 4 to the upper housing 1 and the lower housing 2 through a plurality of connectors; for example, the housing mounting plate 41 may be provided with 4 countersunk screws through which the ear handle 4 can be mounted to the upper housing 1 and the lower housing 2. The cabinet mounting plate 42 has a plurality of (e.g., 2) oblong holes 421, through which the hot-swappable converter module is fixedly mounted to the cabinet, for example, by using cabinet screws passing through the oblong holes 421 to fix it.

[0031] The hot-swappable converter module provided in the embodiment of the present invention is designed to have a device size of 445mm in width and 130mm in height (3U) to address the problems of poor installation adaptability and inefficient maintenance of the prior art solutions. It can be installed in a standard cabinet, and the mounting screws are designed to the front panel ear handles, which can be fixed to the cabinet mounting holes. The standard U height allows the device to be installed up and down in a standard cabinet, making it convenient for parallel use.

[0032] Optionally, based on Figure 1It is not difficult to see that both the upper case 1 and the lower case 2 are four-sided structures, and the upper case 1 and the lower case 2 have step interlocking structures on both sides and the back; the upper case 1 is wrapped on both sides outside the step edge of the lower case 2; at the same time, there are two protruding step platforms supporting the inside of the lower case 2, and in order to increase the ventilation volume at the rear, the step edge of the lower case 2 is made the narrowest, and the step edge width of the upper case 1 is increased. For example, the two cases can be connected by 9 screws, and the joints of the upper case 1, the lower case 2 and the fan panel 3 all have step interlocking structures. After the three are connected, the joints support each other, increasing the overall structural strength and fixation stability.

[0033] Alternatively, if Figure 3 As shown, Figure 3 The specific structural schematic diagram of the upper casing 1 is shown. The upper casing 1 includes: an upper casing left plate 11, an upper casing right plate 12, an upper casing top plate 13, an upper casing rear plate 14, an anti-drop spring 15 and a guide pin 16. The upper casing 1 is a sheet metal part formed by stamping and bending. The upper casing rear plate 14 is bent from the upper casing top plate 13 and is fixedly connected to the upper casing left plate 11 and the upper casing right plate 12 as a whole. The upper casing left plate 11 and the upper casing right plate 12 have similar structures. The upper casing left plate 11 has an upper casing left plate step-down bending edge 111 for connecting the fan panel 3; the fixed connecting member 5 (such as a fixing screw) connects the upper casing 1, the lower casing 2 and the ear handle 4 through a screw hole 113 (such as a countersunk screw hole). The side support step-down edge 112 is used to prop up the side of the lower casing. The anti-drop spring 15 can be made of stainless steel and can be riveted to the upper case left plate 11 by rivets; the front edge of the upper case top plate 13 is bent to form an upper case top plate step edge 131, which is used to support the upper side of the fan panel 3 to prevent the latter from deforming downward. The upper case top plate 13 is also riveted with a number of first nut columns 132, which are used to fix and install the power electronic device unit placed inside it, including the fan power supply system, etc. The upper case back plate 14 has upper case back plate bent edges 141 on both sides. The upper case back plate bent edges 141 have openings and are riveted to the upper case left plate 11 and the upper case right plate 12. The upper case back plate 14 is punched with an array of ventilation holes 142, which improves the ventilation efficiency of the case while also playing a protective role. The upper housing rear plate 14 has a plurality of (eg, 3) countersunk screw holes 144, through which fixing screws are connected to the upper and lower housings via the countersunk screw holes 144 and nuts, and the rear support step edge 115 can prop up the rear of the lower housing.

[0034] The inventors found that when assembling existing equipment, the input and output and signal cables must be connected through plug-in terminals, and after the equipment is installed, the cables must be connected and fixed manually, which reduces the efficiency of installation, maintenance and disassembly. Therefore, the embodiments of the present invention are further improved.

[0035] Alternatively, if Figure 3As shown, the upper housing rear plate 14 also includes: a terminal hole 143, the terminal hole 143 is used to expose various terminals on the power electronic device unit installed inside the upper housing 1 and connect to the external plug-in terminal. It can be understood that the terminal hole 143 is used for equipment input, output and communication cable connection. The plug-in terminal female head is installed on the equipment, and it can be connected after plugging with the plug-in terminal male head connected to the external cable. The male head can be manually plugged in and fixed to the upper and lower housings 2 by screws, or it can be installed on the terminal panel of the cabinet. The terminal plug-in can be realized by pushing the hot-swappable converter module into the cabinet. These two connection methods are convenient for users to connect the design under different usage conditions. When the equipment is maintained and replaced, the cable can be separated by pulling it outward, which is convenient for equipment maintenance.

[0036] Alternatively, if Figure 1 As shown, the anti-drop spring piece 15 is an integrally formed structure having a first snap-in protrusion 151 and a second snap-in protrusion 152. The second snap-in protrusion 152 is arc-shaped; the first snap-in protrusion 151 can be triangular. When the hot-swappable converter module is pushed into the cabinet, the first snap-in protrusion 151 and the second snap-in protrusion 152 are sequentially squeezed into the hot-swappable converter module from the slot of the upper housing 1 by the cabinet column. For example, the hypotenuse of the triangular first snap-in protrusion 151 and the arc edge of the arc-shaped second snap-in protrusion 152 can be squeezed into the device by the cabinet column, so the device can be directly pushed into the cabinet. When the hot-swappable converter module is pulled out from the cabinet, the second clamping protrusion 152 directly slides out of the cabinet column, and the first clamping protrusion 151 is blocked by the cabinet column. For example, the vertical surface of the triangular first clamping protrusion 151 will be blocked by the cabinet column to prevent the device from being directly pulled out. The operator needs to press the arc part of the second clamping protrusion 152 by hand to drag the triangular first clamping protrusion 151 into the casing, and then the device can be pulled out of the cabinet. This device prevents the device from being easily pulled out and falling when the operator is not prepared, causing injury.

[0037] By installing an anti-drop spring 15 on the upper housing 1, when the device is pulled out from the cabinet, the spring can lock the device when the device is pulled out to 4 / 3. The device can be completely pulled out only by pressing the anti-drop spring 15. This device prevents the device from being easily pulled out and falling when the operator is not prepared, causing injury.

[0038] Alternatively, if Figure 4 As shown, Figure 4The specific structural schematic diagram of the lower casing 2 is shown. The lower casing 2 includes: a lower casing left plate 21, a lower casing right plate 22, a lower casing bottom plate 23 and a lower casing rear plate 24. The lower casing 2 is a sheet metal part formed by stamping and bending. The lower casing left plate 21 and the lower casing right plate 22 are symmetrical in structure, and a step flange 221 is folded out on the upper edge, which is used to support the interior of the upper casing 1, such as the interior of the upper casing left plate 11 and the upper casing right plate 12, and plays a role of limiting, which is convenient for the installation of the upper and lower casings. A plurality of (such as 4) nuts 222 are riveted on the flange of the lower casing right plate 22, which is used to connect to the upper casing 1 through a fixed connector 5 (such as a fixing screw). The lower casing right plate 22 also has multiple (such as 2) equipment mounting round nuts 223 for fixing the ear handle 4, and a lower casing right plate step-down bending edge 224 for connecting the fan panel 3, and the lower casing right plate step-down bending edge 224 is installed with round nuts.

[0039] A plurality of second nut columns 231 are riveted on the bottom plate 23 of the lower casing, which are used to fix the power electronic device unit inside the lower casing 2. The front part of the bottom plate 23 of the lower casing is bent to form a lower casing bottom plate difference edge 232, which is used to support the bottom of the fan panel 3 to prevent the latter from deforming upward. There are lower casing back plate bending edges 241 on both sides of the lower casing back plate 24. The lower casing back plate bending edges 241 have openings and are riveted to the lower casing left plate 21 and the lower casing right plate 22. The lower casing back plate 24 is punched out with an array of ventilation holes 142, which improves the ventilation efficiency of the casing and also plays a protective role. The lower casing back plate difference edge 245 on the lower casing back plate 24 is used to support the upper casing 1, and the upper riveted round nut is used to connect with the upper casing 1 by screws. It should be noted that there are two sprouting screw holes 244 on each terminal hole 143, which are used to fix the male terminal.

[0040] In addition, the inventors have also found that the existing equipment does not have a physical switch, and when the equipment is maintained, the main power supply must be cut off, the equipment must be shut down, and then the equipment must be replaced, which results in low equipment maintenance efficiency. Therefore, the embodiments of the present invention have been further improved.

[0041] Alternatively, if Figure 5 As shown, Figure 5 The schematic diagram of the structure of the fan panel 3 is shown. The fan panel 3 comprises: a fan panel left plate 31, a fan panel right plate 32, a fan panel top plate 33, a fan panel bottom plate 34, a fan panel front plate 35 and a toggle switch 36.

[0042] The fan panel 3 is a sheet metal part formed by stamping and bending. The fan panel top plate 33 and the fan panel bottom plate 34 are fixedly connected to the fan panel left plate 31 and the fan panel right plate 32 respectively through the flange structure and rivets 311; the fan panel left plate 31 and the fan panel right plate 32 are symmetrical in structure, and the fan panel left plate 31 has a fan panel left plate difference edge 312 for supporting the lower casing 2 to prevent the left and right plates of the lower casing from deforming inward, and a square hole 313 is provided for the tongue of the toggle switch 36 to extend out of the casing. By designing and installing a toggle switch 36, the device can be locked to the cabinet to prevent the device from being unplugged when it is powered on, which can cause harm. When the toggle switch is operated during equipment maintenance, the device is powered off. At the same time, the lock on the cabinet is also released. After removing the cabinet fixing screws, the device can be pulled out. Further, if Figure 2 As shown, the housing mounting plate 41 of the ear-hanging handle 4 further includes: an elongated hole 412 , and the elongated hole 412 is used to allow the tongue of the toggle switch 36 to extend out.

[0043] The fan panel top plate 33 and the fan panel bottom plate 34 are symmetrical, and the front edge of the fan panel bottom plate 34 is bent to form a plurality of fan panel bottom plate step edges 341, which are used to support the lower housing 2 to prevent the latter from deforming upward; the fan panel front plate 35 has a plurality of (e.g., 12) fixing holes 351 for fixing the fan and the fan cover through 12 fan screws 37. The fan panel 3 is fixed to the countersunk holes 352 on the upper and lower housing components through 4 screws, and a bulging fan hole 353 is also formed on the fan panel front plate 35 by cutting and stamping.

[0044] Alternatively, if Figure 2 As shown, the handle portion 43 of the ear-hanging handle 4 has a hand-gripping hole 431 and two flanges 432 , and the flanges 432 are used to prevent the handle from scratching the hand.

[0045] The following will introduce a method for installing a hot-swappable converter module provided by an embodiment of the present invention.

[0046] like Figure 6 As shown, Figure 6 The schematic diagram of the installation of the upper housing 1 and the lower housing 2 of the hot-swappable converter module is shown. The fixing screws connect the rear parts of the upper and lower housings through the countersunk holes provided on the left plate, right plate and rear plate of the upper housing, and the riveted round nuts on the step-difference edges of the left plate, right plate and rear plate of the lower housing. The upper edges of the left plate, right plate and rear plate of the lower housing are folded into step-difference flanges, which are supported inside the left plate and right plate of the upper housing. The lower edges of the left plate, right plate and rear plate of the upper housing are folded into step-difference flanges, which are supported inside the left plate and right plate of the upper housing. The step-difference edges also play a role of limiting, which is convenient for the installation of the upper and lower housings. After the upper and lower housings are installed, the installation space and air duct inside the equipment are formed.

[0047] like Figure 7The schematic diagram of the interlocking of the fan panel and the upper and lower casings is shown. The fan panel and the relative step edges on the upper and lower casings are inserted into each other to form a hinge structure, which can be connected by rotation and at the same time limit the relative lateral displacement.

[0048] like Figure 8 As shown in the schematic diagram of the installation of the plug-in terminal housing, the rear of the upper and lower housings are equipped with female power communication terminals with a plug-in structure, and the male plug-in terminals with external cables are manually plugged into place and fixed to the upper and lower housings by screws.

[0049] like Fig. 9 As shown in the installation diagram of the plug-in terminal panel, the plug-in male connector with external cables is installed on the terminal panel of the cabinet. The terminals can be plugged in after the converter equipment is pushed into the cabinet.

[0050] The hot-swappable converter module provided by the embodiment of the present invention has the following effects: after the upper housing, the lower housing and the fan panel are assembled, a closed air duct is formed inside the power module, and the air outlet opening rate of the rear plate of the upper and lower housings is large and the wind resistance is small, so that the fan air duct is unobstructed, and the flowing airflow takes out the heat of the internal heating device and prevents the accumulation of dust from the outside. The upper and lower housings have step-difference interlocking structures on both sides and the back. The two housings are connected by 9 screws, and the front is supported by the front panel and the ear handle. There is a step-difference structure at the junction of the upper and lower housings and the fan panel. After the three are connected, the docking point supports each other, increasing the rigidity and stability of the overall structure. The rear of the upper and lower housings is equipped with a power communication terminal female head, which can be manually plugged into the male head and then fixed to the upper and lower housings by screws. The equipment female head can also be plugged into the male head on the terminal panel installed in the cabinet, which is convenient for users to connect wires in different usage situations. The guide pins at the back of the housing facilitate terminal insertion. A stainless steel anti-drop spring is riveted to the rear of the lower housing. When the device is pulled out of a standard cabinet, the vertical surface of the triangular part will be blocked by the cabinet column to prevent the device from being pulled out directly. This device prevents the device from being easily pulled out and falling when the operator is not prepared, causing injury. A toggle switch is installed on the front panel of the device. When the toggle switch is turned on, the switch tongue extends out of the device to prevent the device from being pulled out of the cabinet. When the toggle switch is turned off, the device is powered off and can be pulled out of the cabinet. This device prevents the device from being easily pulled out when it is not powered off, thereby avoiding injury to the operator or damage to the device.

[0051] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technical solution that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
