Description

Technical Field

[0001] This application relates to the field of power supply technology, and in particular to a power supply device. Background Technology

[0002] Power conversion devices are a core component of power supply equipment. When installing power conversion devices, they typically need to be inserted into the equipment cabinet of the power supply equipment. After the power conversion device is inserted into the equipment cabinet, its terminals (e.g., input terminals or output terminals) are connected to metal busbars (e.g., copper busbars) inside the equipment cabinet.

[0003] To ensure accurate connection between the terminals of the power converter and the metal busbars, related technologies often use the inner wall of the equipment cabinet to provide a rough guide for the power converter's casing. However, this insertion / removal method can lead to poor contact or even inaccurate connection between the power converter's terminals and the metal busbars inside the cabinet. This increases the difficulty of installing the power converter, affects the efficiency of insertion and removal, and may also cause wear on the metal busbar terminals. Utility Model Content

[0004] This application provides a power supply device that guides or positions the installation of a power conversion device through the cooperation of plugs and slots, reducing the installation difficulty of the power conversion device, increasing the probability of accurate connection between the terminals of the power conversion device and the metal busbar, and reducing the possibility of wear on the terminals caused by the metal busbar.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This application provides a power supply device, which includes an equipment cabinet, multiple power conversion devices, multiple metal bars, and multiple plugs. The equipment cabinet has a mounting opening facing one side in the thickness direction of the equipment cabinet. The multiple power conversion devices are installed inside the equipment cabinet, and the mounting opening is used for inserting or removing the multiple power conversion devices along the thickness direction of the equipment cabinet. The multiple metal bars are fixed inside the equipment cabinet, and each power conversion device includes one or more terminals disposed opposite to the mounting opening. One terminal is used to connect to at least one of the multiple metal bars. The multiple plugs are fixed inside the equipment cabinet, and each power conversion device has one or more slots. The outer wall surface of each power conversion device includes a first end face opposite to the mounting opening, and one or more slots penetrate the first end face. One slot is used for inserting one plug.

[0007] Power conversion devices in power supply equipment convert input electrical energy into power and then output it. For example, in the case of a charging device, the power conversion device can output the converted electrical energy to a charging gun, which can then charge the device to be charged (e.g., an electric vehicle). When multiple power conversion devices need to be installed in the equipment cabinet of the power supply equipment, each power conversion device is inserted into the cabinet through its mounting port. The power conversion device inserted into the cabinet will connect to the metal busbar (e.g., plug-in). During the installation of multiple power conversion devices, the plugs in the equipment cabinet and the slots on the power conversion devices cooperate to form a guiding structure. For example, each power conversion device has two slots, which correspond one-to-one with two plugs in the multiple plugs in the equipment cabinet. Each slot is used to insert one corresponding plug. When installing one power conversion device, two plugs in the equipment cabinet are inserted into the corresponding slots on that power conversion device. The slots guide or position the plugs, adjusting the installation position of the power conversion device so that the terminals on the power conversion device can be accurately connected to the metal busbar in the equipment cabinet.

[0008] In summary, by using inserts and slots to guide or position the installation of power conversion devices, the installation difficulty of power conversion devices is reduced, the probability of accurate connection between the terminals of power conversion devices and the metal busbars in the equipment cabinet is increased, the installation efficiency of power conversion devices is improved, and the possibility of wear on the terminals caused by the metal busbars is reduced.

[0009] In one embodiment, multiple power conversion devices are arranged along the thickness direction of each power conversion device. The dimensions of each power conversion device in its width direction and its length direction are both greater than its thickness direction. The length direction of each power conversion device is parallel to the thickness direction of the equipment cabinet. The outer wall surface of each power conversion device also includes a second end face and a third end face arranged in its width direction. One or more slots include a first slot that penetrates through the second end face. The slot of the first slot on the second end face is used for one of the multiple inserts to pass through.

[0010] Each power converter has its shortest dimension in its thickness direction, making each power converter flat. Multiple power converters are arranged along their thickness direction, which facilitates installation and interconnection. Multiple inserts are positioned on the sides of the power converters in the width direction, with one insert extending into the first slot from one side of the power converter's width. These inserts do not occupy space between adjacent power converters, nor do they occupy space on the side of the power converters away from the mounting opening, resulting in a more rational placement of the inserts. Furthermore, the flat shape of the power converters allows for guidance and positioning of the ends in the width direction, facilitating easy adjustment of each power converter's position.

[0011] In one embodiment, each power conversion device has multiple slots, and the multiple slots further include a second slot that extends through a third end face. The slot of the second slot is located in a notch on the third end face for another of the multiple inserts to pass through.

[0012] By guiding or positioning both ends of each power converter in the width direction, the position of the power converter can be further improved to an ideal state (a state in which the terminals are accurately connected to the metal busbar), which increases the probability of accurate connection between the terminals of the power converter and the metal busbar, and further reduces the possibility of wear on the terminals caused by the metal busbar.

[0013] In one embodiment, each power conversion device includes a housing and one or more power devices located within the housing, the housing having one or more openings; each power conversion device also includes one or more mounting blocks located within the housing, each mounting block having a limiting groove, an opening communicating with a limiting groove, and a slot including a communicating opening and a limiting groove; the outer wall surface of the housing includes a first end face and a second end face, the opening of the first slot penetrating the first end face and the second end face, and the limiting groove of the first slot recessing from the surface of the mounting block facing the first end face toward the mounting opening and penetrating the surface of the mounting block facing the second end face.

[0014] The opening on the device housing and the limiting groove on the mounting block form at least part (all or part) of the slot. The limiting groove on the mounting block increases the depth of the slot, that is, it makes the area of ​​the power conversion device with the slot thicker, so that the insert can be inserted deeper, which is beneficial to limiting the insert and reducing the possibility of the insert coming out of the slot.

[0015] In one embodiment, each power conversion device includes a housing and one or more power devices located within the housing; each power conversion device further includes one or more mounting blocks located within the housing, the housing having one or more openings, each mounting block having a slot and a protrusion surrounding the slot, the protrusion of one mounting block passing through an opening, the slot on one of the mounting blocks being a first slot, and the surface of the protrusion surrounding the first slot exposed outside the housing through the opening including at least a portion of a first end face and at least a portion of a second end face.

[0016] The slots are located on the mounting block, increasing the thickness of the area where the power conversion device has slots and thus increasing the depth of the slots. This allows the inserts to be inserted deeper, which is beneficial for limiting the position of the inserts. Furthermore, the protrusions also serve to position the mounting block. By passing through the opening, the protrusions can be used to position the mounting block, reducing the possibility of misalignment between the slots on the mounting block and the openings on the device housing.

[0017] In one embodiment, the device housing has one or more positioning posts extending toward its own interior, and each mounting block has a positioning groove, with one positioning post inserted into the positioning groove of one mounting block; or, the device housing has one or more positioning grooves, and each mounting block has a positioning post, with one positioning post of one mounting block inserted into the positioning groove.

[0018] For each power conversion device, during the installation of the mounting block onto the device housing, if the positioning post is on the mounting block and the positioning slot is on the device housing, the positioning post on the mounting block is inserted into the positioning slot on the device housing; if the positioning slot is on the mounting block and the positioning post is on the device housing, the positioning post on the device housing is inserted into the positioning slot on the mounting block. Through the cooperation between the positioning post and the positioning slot, the position of the mounting block can be determined, facilitating rapid installation.

[0019] In one embodiment, the power supply equipment further includes one or more guide posts, which are fixed inside the equipment cabinet, and each power conversion device further includes one or more guide cylinders disposed away from the mounting opening; or, the power supply equipment further includes one or more guide cylinders, which are fixed inside the equipment cabinet, and each power conversion device further includes one or more guide posts disposed away from the mounting opening; each guide cylinder has a guide hole inside, the size of the guide hole in the width direction of the equipment cabinet is larger than the size in the height direction of the equipment cabinet, and one guide hole is used for inserting one guide post.

[0020] During the installation of multiple power converters, if the guide cylinder is fixed to the power converter and the guide post is fixed inside the equipment cabinet, then the guide post inside the equipment cabinet, after being inserted into the guide cylinder on the power converter, can position and guide the power converter. Similarly, if the guide cylinder is fixed inside the equipment cabinet and the guide post is fixed to the power converter, then the guide post on the power converter, after being inserted into the guide cylinder inside the equipment cabinet, can also position and guide the power converter. Through the cooperation between the guide cylinder and the guide post, the installation difficulty of the power converter is reduced, the probability of accurate connection between the terminals of the power converter and the metal busbar is increased, the installation efficiency of the power converter is improved, and the possibility of wear on the terminals caused by the metal busbar is reduced.

[0021] Furthermore, the guide hole's dimension in the width direction of the equipment cabinet is larger than its dimension in the height direction; that is, the guide hole is an oblong hole, allowing for positional deviation of the guide post in the width direction of the equipment cabinet. In this way, by designing the dimensions of the guide hole, the fit between the guide cylinder and the guide post serves as coarse guidance for the power conversion device. That is, coarse guidance of the power conversion device is first achieved through the fit between multiple guide posts and multiple guide holes, and then precise guidance of the power conversion device is achieved through the fit between the insert and the slot.

[0022] In one embodiment, in each power conversion device, where the end of a guide post facing a guide hole is located at the opening of a guide hole facing a guide post, there is a gap between a slot and a insert.

[0023] During the installation of each power converter, as it is pushed into the equipment cabinet, there is a gap between the mating inserts and slots when the guide post first reaches the guide hole. That is, the guide post inserts into the guide hole first, and the inserts only insert into the slots after the power converter is pushed for a while. This design achieves coarse guidance of the power converter through the interaction of multiple guide posts and guide holes, followed by precise guidance through the interaction of the inserts and slots. This staged guidance, starting with coarse guidance and then moving to precise guidance, gradually adjusts the position of the power converter, ensuring accurate connection between the terminals and the metal busbars.

[0024] In one embodiment, in each power conversion device, where the end of a plug facing the mounting port is located in a slot away from the mounting port, a terminal has a gap with at least one metal bar.

[0025] During the process of pushing the power converter into the equipment cabinet, there is a gap between the terminals and the metal busbar when the insert first reaches the socket. That is, the insert is first inserted into the slot, and the power converter is pushed for a period of time before the terminals on the power converter connect with the metal busbar inside the equipment cabinet. This design first guides and positions the power converter through the interaction between the insert and the slot. After adjusting the position of the power converter, its terminals can be accurately connected to the metal busbar inside the equipment cabinet, improving the installation efficiency of the power converter and reducing the possibility of wear on the terminals caused by the metal busbar.

[0026] In one embodiment, the power supply equipment further includes a plurality of baffles fixed inside the equipment cabinet. The arrangement direction of the plurality of baffles is parallel to the arrangement direction of the plurality of power conversion devices. The space between two adjacent baffles is used for inserting or removing a power conversion device. Each baffle extends along the thickness direction of the equipment cabinet, and at least a portion of each baffle is located on the side of one or more inserts facing the mounting port.

[0027] Multiple baffles act as coarse guides, with adjacent baffles guiding the power conversion device between them, allowing it to be pushed into the equipment cabinet along a predetermined trajectory under the constraint of the adjacent baffles. At least part (or all) of each baffle is located on the side of all the inserts facing the mounting opening. That is, during the process of pushing the power conversion device into the equipment cabinet, each power conversion device first undergoes coarse guiding through the baffles on both sides, and then precise guiding is achieved through the interaction between the inserts and slots. This staged guidance, starting with coarse guiding and then precise guiding, gradually adjusts the position of the power conversion device, ensuring that the terminals of the power conversion device can accurately connect to the metal busbars inside the equipment cabinet.

The charging guns 30 are located outside the equipment cabinet 1 and are used to connect to the device to be charged (e.g., an electric vehicle). The charging guns 30 are connected to the DC power distribution device 20 via corresponding first cables 40. The DC power distribution device 20 controls the on / off state of the circuit between the multiple power conversion devices 2 and the first cables 40. When the DC power distribution device 20 conducts the circuit between the first cables 40 and the multiple power conversion devices 2, the charging guns 30 can output the current after power conversion by the multiple power conversion devices 2.

[0060] In another embodiment, when the power supply device 100 is an integrated charging pile, the power supply device 100 has one or more charging guns 30 and first cables 40.

[0061] Figure 2 An exemplary diagram shows the structure of another power supply device 100, with reference to Figure 2The power supply equipment 100 is a split-type charging pile, comprising a main unit and multiple terminal units. The main unit of the power supply equipment 100 includes an equipment cabinet 1, an AC power distribution device 10, a DC power distribution device 20 (also referred to as a power allocation device), and multiple power conversion devices 2. The AC power distribution device 10, DC power distribution device 20, and multiple power conversion devices 2 are all installed within the equipment cabinet 1. The input terminal of the AC power distribution device 10 is used to connect to a power source (e.g., the power grid). Each power conversion device 2 is used to perform power conversion. The DC power distribution device 20 is connected to multiple terminal units of the power supply equipment 100 via multiple second cables 50 to distribute the DC power output from the multiple power conversion devices 2 to one or more of the terminal units.

[0062] Reference Figure 2 Each terminal section of the power supply equipment 100 includes a terminal cabinet 60, a charging gun 30, and a first cable 40, wherein a portion of a second cable 50 extends into the terminal cabinet 60. Figure 2 In the illustrated embodiment, each terminal section has two charging guns 30 and two first cables 40. Each charging gun 30 is connected to the terminal cabinet 60 via a corresponding first cable 40. When the circuit between the first cable 40 and the second cable 50 is connected, the charging gun 30 can output the current after power conversion by multiple power conversion devices 2.

[0063] In another embodiment, in each terminal portion of the power supply device 100, one or more charging guns 30 and first cables 40 are provided.

[0064] In another embodiment, the power supply device 100 is a power cabinet, for example, a cabinet-type uninterruptible power supply (UPS).

[0065] Figure 3 An exemplary structure of an equipment cabinet 1 is shown, with reference to Figure 3 The equipment cabinet 1 can be any suitable cabinet structure, wherein the equipment cabinet 1 has a thickness direction, a width direction and a height direction, wherein the height direction of the equipment cabinet 1 is parallel to the vertical direction (or the direction of gravity), that is, the height direction of the equipment cabinet 1 is parallel to the Z-axis, the width direction of the equipment cabinet 1 (parallel to the X-axis) and the thickness direction of the equipment cabinet 1 (parallel to the Y-axis) are perpendicular to each other and both perpendicular to the height direction of the equipment cabinet 1.

[0066] Reference Figure 3The equipment cabinet 1 has a mounting opening 11 facing one side along the thickness direction of the equipment cabinet 1. Multiple power conversion devices 2 are installed inside the equipment cabinet 1 through the mounting opening 11, or multiple power conversion devices 2 are pulled out of the equipment cabinet 1 through the mounting opening 11. In other words, the mounting opening 11 of the equipment cabinet 1 is used for inserting or removing multiple power conversion devices 2 along the thickness direction of the equipment cabinet 1.

[0067] In addition, the power supply equipment 100 also includes multiple metal busbars 3 (e.g., copper busbars), Figure 4 An exemplary structure of a metal bar 3 is shown, with reference to Figure 4 The shape and size of each metal bar 3 can be designed according to requirements. Multiple metal bars 3 are located inside the equipment cabinet 1 and away from the mounting port 11, so that multiple metal bars 3 and mounting port 11 form a space for installing multiple power conversion devices 2.

[0068] Each power conversion device 2 has one or more terminals 21 at the end opposite to the mounting port 11. Figure 5 An exemplary structure of terminal 21 is shown, in Figure 5 In the illustrated embodiment, each power conversion device 2 has two terminals 21, for example, one is an input terminal 21 and the other is an output terminal 21. Figure 5 and Figure 4 The diagram shows the view of equipment cabinet 1 from different sides in the thickness direction. For example, the side where the mounting opening 11 is located is the front of equipment cabinet 1. Figure 3 and Figure 4 All views are of equipment cabinet 1 from the front. Figure 5 This is a view of the equipment cabinet 1 from the rear.

[0069] Reference Figure 5 One terminal 21 is used to connect to at least one of the multiple metal busbars 3. For example, multiple terminals 21 correspond one-to-one with multiple metal busbars 3, and one terminal 21 is used to connect to the corresponding metal busbar 3; or, for example, all the metal busbars 3 are divided into multiple groups, each group of metal busbars 3 includes two or more metal busbars 3, each terminal 21 has a corresponding group of metal busbars 3, and one terminal 21 is used to connect to the corresponding group of metal busbars 3. Current flows into the power conversion device 2 through the metal busbars 3, or current flows out of the power conversion device 2 through the metal busbars 3.

[0070] When installing the power converter 2, it is typically necessary to insert the power converter 2 into the equipment cabinet 1 of the power supply equipment 100. After the power converter 2 is inserted into the equipment cabinet 1, one or more terminals 21 of each power converter 2 will connect to the metal busbar 3 inside the equipment cabinet 1. Directly plugging and unplugging the power converter 2 can cause poor contact or even prevent accurate connection between the terminals 21 of the power converter 2 and the metal busbar 3 inside the equipment cabinet 1, increasing the difficulty of installing the power converter 2, affecting the efficiency of plugging and unplugging the power converter 2, and may also cause wear on the terminals 21 of the metal busbar 3.

[0071] To ensure accurate connection between the terminals 21 of the power conversion device 2 and the metal busbars 3 within the equipment cabinet 1, this application employs a guiding structure to guide the power conversion device 2. The power supply equipment 100 also includes multiple connectors 4. Figure 6 An exemplary structure of insert 4 is shown. Figure 7 for Figure 6 An enlarged view at point A in the middle, refer to Figure 6 and Figure 7 Multiple inserts 4 are fixed inside the equipment cabinet 1. In one embodiment, each insert 4 may be a metal sheet. In another embodiment, each insert 4 comprises multiple stacked metal sheets. Furthermore, in one embodiment, the multiple inserts 4 are integrally connected with other metal structures within the equipment cabinet 1; in another embodiment, each insert 4 is an independent structure and is fixed inside the equipment cabinet 1 by welding or screws.

[0072] Each power conversion device 2 has one or more slots 22. Figure 8 An exemplary structure of a slot 22 is shown, in Figure 8 In the illustrated embodiment, each power conversion device 2 has one slot 22; in other embodiments, each power conversion device 2 has multiple slots 22. (Refer to...) Figure 8 Each power conversion device 2 has an outer wall surface including a first end face 201 that is away from the mounting port 11 (arrow 11 indicates the position of the mounting port 11 on the equipment cabinet 1 after the power conversion device 2 is installed). The slot 22 on each power conversion device 2 passes through the first end face 201 of the power conversion device 2 (that is, the slot 22 on each power conversion device 2 extends to the first end face 201 of the power conversion device 2). Figure 9 This illustrates a structure in which the insert 4 and the slot 22 mate. Figure 9 for Figure 5 (Partial view), refer to Figure 9 A slot 22 is used for inserting a piece 4. For example, multiple pieces 4 correspond one-to-one with multiple slots 22, and each piece 4 is inserted into the corresponding slot 22.

[0073] During the installation of multiple power conversion devices 2, the inserts 4 inside the equipment cabinet 1 and the slots 22 on the power conversion devices 2 cooperate to form a guiding structure. For example, each power conversion device 2 has a slot 22. When installing one of the power conversion devices 2, an insert 4 inside the equipment cabinet 1 is inserted into the corresponding slot 22 on the power conversion device 2. The slot 22 guides or positions the insert 4, adjusting the installation position of the power conversion device 2 so that the terminals 21 on the power conversion device 2 can be accurately connected to the metal busbars 3 inside the equipment cabinet 1.

[0074] In summary, by using the cooperation of the insert 4 and the slot 22 to guide or position the installation of the power conversion device 2, the installation difficulty of the power conversion device 2 is reduced, the probability of accurate connection between the terminal 21 of the power conversion device 2 and the metal busbar 3 in the equipment cabinet 1 is increased, the installation efficiency of the power conversion device 2 is improved, and the possibility of wear on the terminal 21 caused by the metal busbar 3 is reduced.

[0075] In one embodiment, reference is made to... Figure 8 Each power conversion device 2 has two perpendicular width directions, thickness directions, and length directions. The dimensions of each power conversion device 2 in its width direction and its length direction are both greater than its dimensions in its thickness direction. That is, the dimension of each power conversion device 2 in its thickness direction is the shortest, making each power conversion device 2 flat.

[0076] Reference Figure 9 Multiple power conversion devices 2 are arranged along the thickness direction of each power conversion device 2, which facilitates the installation and interconnection of multiple power conversion devices 2. Figure 9 The illustrated embodiments (which may also be referenced) Figure 5 The length direction of each power conversion device 2 is parallel to the thickness direction of the equipment cabinet 1 (parallel to the Y-axis), the thickness direction of each power conversion device 2 is parallel to the width direction of the equipment cabinet 1 (parallel to the X-axis), and the width direction of each power conversion device 2 is parallel to the height direction of the equipment cabinet 1 (parallel to the Z-axis).

[0077] Reference Figure 8 and Figure 9Each power conversion device 2's outer wall surface also includes a second end face 202 and a third end face 203 arranged in its own width direction. All slots 22 on each power conversion device 2 include a first slot 221. For example, each power conversion device 2 has one slot 22, which is the first slot 221; or, for example, each power conversion device 2 has multiple slots 22, and one of the multiple slots 22 is the first slot 221. The first slot 221 of each power conversion device 2 passes through the second end face 202 of the power conversion device 2, and the slot 221 located on the second end face 202 is used for one of the multiple inserts 4 to pass through.

[0078] In this configuration, at least one or more of the multiple inserts 4 are positioned on the side of the power conversion device 2 in the width direction, such that one of the inserts 4 is positioned on the side of the power conversion device 2 in the width direction. Figure 9 The multiple inserts 4 extend into the first slot 221 from one side (in the Z-axis direction), so that they do not occupy the space between two adjacent power conversion devices 2, nor the space on the side of the multiple power conversion devices 2 away from the mounting port 11, making the position of the multiple inserts 4 more reasonable. In addition, the power conversion devices 2 are flat, and the ends of each power conversion device 2 in the width direction are guided or positioned, which makes it easier to adjust the position of each power conversion device 2.

[0079] In another embodiment, each power conversion device 2 has a plurality of slots 22, and all slots 22 of each power conversion device 2 include a second slot 222 in addition to the first slot 221. Figure 10 An exemplary structure of a second slot 222 is shown, wherein the second slot 222 of each power conversion device 2 passes through the third end face 203 of the power conversion device 2, and the slot of the second slot 222 on the third end face 203 is used for another insert 4 of a plurality of inserts 4 to pass through (the number of inserts 4 can be two or more). Figure 11 An exemplary diagram shows another structure for insert 4, which is similar to... Figure 9 The difference between insert 4 and the one in the middle is that... Figure 11 Each insert 4 is used to insert into the corresponding second slot 222.

[0080] For example, each power conversion device 2 has two slots 22 (first slot 221 and second slot 222). The two slots 22 (first slot 221 and second slot 222) correspond one-to-one with two plugs 4 among the multiple plugs 4 in the equipment cabinet 1. Each slot 22 is used to insert a corresponding plug 4. When one of the power conversion devices 2 is installed, two plugs 4 in the equipment cabinet 1 will be inserted into the corresponding slots 22 on the power conversion device 2. The slots 22 guide or position the plugs 4, adjust the installation position of the power conversion device 2, and enable the terminals 21 on the power conversion device 2 to be accurately connected to the metal busbars 3 in the equipment cabinet 1.

[0081] In the case where the power conversion device 2 has a first slot 221 and a second slot 222, both ends of each power conversion device 2 in the width direction are guided or positioned, which can further make the position of the power conversion device 2 approach an ideal state. The ideal state of the position of the power conversion device 2 refers to the state in which the terminal 21 can be accurately connected to the metal busbar 3, which increases the probability of the terminal 21 of the power conversion device 2 being accurately connected to the metal busbar 3 in the equipment cabinet 1, and further reduces the possibility of the metal busbar 3 causing wear to the terminal 21.

[0082] In another embodiment, where multiple power conversion devices 2 are arranged along the thickness direction of each power conversion device 2, after the multiple power conversion devices 2 are installed inside the equipment cabinet 1, Figure 12 An exemplary diagram shows the structure of another equipment cabinet 1, with reference to Figure 12 The length direction of each power conversion device 2 is parallel to the thickness direction of the equipment cabinet 1 (parallel to the Y-axis), the thickness direction of each power conversion device 2 is parallel to the height direction of the equipment cabinet 1 (parallel to the Z-axis), and the width direction of each power conversion device 2 is parallel to the width direction of the equipment cabinet 1 (parallel to the X-axis).

[0083] Regarding the structure of each slot 22, in one embodiment, each power conversion device 2 includes a device housing 23 and one or more power devices 24 located within the device housing 23. Figure 13 An exemplary structure of a device housing 23 is shown, with reference to Figure 13The position of the power device 24 is merely an example and is not a limitation on its position. Furthermore, each power conversion device 2 includes one or more mounting blocks 25 located within the device housing 23. The number of mounting blocks 25 is the same as the number of slots 22. The device housing 23 has one or more openings 231, the number of which is also the same as the number of slots 22. Each mounting block 25 has a limiting groove 251, with one opening 231 communicating with one limiting groove 251. For example, multiple openings 231 and multiple limiting grooves 251 are provided, with each opening 231 corresponding to a specific limiting groove 251.

[0084] Each slot 22 includes an interconnected opening 231 and a limiting groove 251. That is, each slot 22 on each power conversion device 2 includes an interconnected opening 231 and a limiting groove 251 within that power conversion device 2; or, the interconnected opening 231 and the limiting groove 251 constitute at least a portion (all or part) of a slot 22. The limiting groove 251 on the mounting block 25 increases the depth of the slot 22, making the area of ​​the power conversion device 2 with the slot 22 thicker. This allows the insert 4 to be inserted deeper, which helps to limit the insertion of the insert 4 and reduces the possibility of the insert 4 detaching from the slot 22.

[0085] exist Figure 13 In the illustrated embodiment, the outer wall surface of the device housing 23 includes a first end face 201, a second end face 202, and a third end face 203 (the third end face is an auxiliary reference). Figure 10 A portion of the slot 22 includes an opening 231 that extends through the first end face 201 and the second end face 202, for example, Figure 13 The opening 231 of the first slot 221 penetrates the first end face 201 and the second end face 202; the opening 231 of another portion of the slots 22 penetrates the first end face 201 and the third end face 203, for example, the opening 231 of the second slot 222 penetrates the first end face 201 and the third end face 203. Referring to... Figure 13 A limiting groove 251 (e.g., the limiting groove 251 of the first slot 221) that connects the opening 231 through the first end face 201 and the second end face 202 is recessed from the surface of the mounting block 25 toward the first end face 201 toward the mounting opening 11, and the limiting groove 251 also penetrates the surface of the mounting block 25 toward the second end face 202. Furthermore, a limiting groove 251 (e.g., the limiting groove 251 of the second slot 222) that connects the opening 231 through the first end face 201 and the third end face 203 is recessed from the surface of the mounting block 25 toward the first end face 201 toward the mounting opening 11, and the limiting groove 251 also penetrates the surface of the mounting block 25 toward the third end face 203.

[0086] In another embodiment, Figure 14 An exemplary diagram shows the structure of another device housing 23, with reference to Figure 14 Each power conversion device 2 includes a housing 23 and one or more power devices 24 located within the housing 23. Each power conversion device 2 also includes one or more mounting blocks 25 located within the housing 23, the number of mounting blocks 25 being the same as the number of slots 22. Each mounting block 25 has a slot 22. The housing 23 has one or more openings 231, the number of which is also the same as the number of mounting blocks 25. One opening 231 exposes a slot 22 of one mounting block 25; that is, each opening 231 exposes a corresponding slot 22 of the mounting block 25, allowing the insert 4 to pass through the opening 231 and enter the slot 22. By placing the slots 22 on the mounting blocks 25, the area of ​​the power conversion device 2 with the slots 22 is thicker, allowing the insert 4 to be inserted deeper, which is beneficial for limiting the insertion of the insert 4. Furthermore, a portion of the mounting block 25 passes through the corresponding opening 231, serving to position the mounting block 25 and reduce the possibility of misalignment between the slot 22 of the mounting block 25 and the opening 231 on the device housing 23. It is understood that in this embodiment, the first end face 201 and the second end face 202 (or the third end face 203) through which the slot 22 passes are both located on the corresponding mounting block 25.

[0087] In one embodiment, reference is made to... Figure 14 The portion of the mounting block 25 that passes through the opening 231 is a protrusion 252 of the mounting block 25. The protrusion 252 is annular and surrounds the slot 22; that is, a portion of the slot 22 is located within the area enclosed by the protrusion 252. Figure 14 In the illustrated embodiment, one of the slots 22 on the mounting block 25 is a first slot 221, and a protrusion 252 surrounding the first slot 221 is exposed on the surface outside the device housing 23 through a corresponding opening 231, including at least a portion (partial or complete) of the first end face 201 and at least a portion (partial or complete) of the second end face 202. Furthermore, in the case where multiple slots 22 also include a second slot 222, one of the slots 22 on the mounting block 25 is a second slot 222, and a protrusion 252 surrounding the second slot 222 is exposed on the surface outside the device housing 23 through a corresponding opening 231, including a portion of the first end face 201 (another portion of the first end face 201 is located on the protrusion surrounding the first slot 221) and at least a portion of the third end face 203.

[0088] In another embodiment, the portion of the mounting block 25 that passes through the opening 231 consists of multiple limiting plates or limiting posts of the mounting block 25, which serve to position the mounting block 25.

[0089] In the case where the power conversion device 2 includes a device housing 23 and a mounting block 25, in order to facilitate the installation of the mounting block 25, in one embodiment, the device housing 23 has one or more positioning posts 5 extending toward its own interior. Figure 15 An exemplary structure of a positioning post 5 is shown, with reference to Figure 15 Each mounting block 25 has a positioning groove 6, and a positioning post 5 is inserted into the positioning groove 6 of one mounting block 25. For example, the device housing 23 has multiple positioning posts 5 extending inwards, and each of the multiple mounting blocks 25 has a positioning groove 6. The multiple positioning posts 5 correspond one-to-one with the multiple mounting blocks 25, and each positioning post 5 is inserted into the positioning groove 6 of its corresponding mounting block 25. For each power conversion device 2, during the process of installing the mounting block 25 on the device housing 23, the position of the mounting block 25 can be positioned by the cooperation between the positioning post 5 and the positioning groove 6, which facilitates the rapid installation of the mounting block 25.

[0090] In another embodiment, Figure 16 An exemplary diagram shows another structure of the positioning post 5, with reference to Figure 16 The device housing 23 has one or more positioning slots 6, and each mounting block 25 has a positioning post 5. The positioning post 5 of one mounting block 25 is inserted into a positioning slot 6. For example, the device housing 23 has multiple positioning slots 6, and each of the multiple mounting blocks 25 has a positioning post 5. The multiple positioning slots 6 are set one-to-one with the multiple mounting blocks 25, and the positioning post 5 on each mounting block 25 is inserted into a corresponding positioning slot 6.

[0091] After each mounting block 25 is installed at a designated position on the device housing 23 by the cooperation of the positioning post 5 and the positioning groove 6, the mounting block 25 can also be fixedly connected to the device housing 23 by welding or screw connection.

[0092] Furthermore, in order to fully utilize the guiding function of the insert 4 and the slot 22, in one embodiment, for each power conversion device 2 (with Figure 17 Taking a power conversion device 2 as an example, when the end of each insert 4 facing the mounting port 11 (arrow 11 indicates the position of the mounting port 11) is located in the corresponding slot 22 away from the opening of the mounting port 11, that is, when the end of each insert 4 facing the mounting port 11 is flush with the opening of the corresponding slot 22 away from the opening of the mounting port 11, for example, Figure 17 The end of the middle insert 4 facing the mounting port 11 and Figure 17 When the dashed line L1 is aligned, there is a gap between each terminal 21 on the power conversion device 2 and one or more metal bars 3 corresponding to that terminal 21 (one or more metal bars 3 for insertion into that terminal 21).

[0093] In this way, when the power conversion device 2 is pushed into the equipment cabinet 1, there is a gap between the terminal 21 and the metal bar 3 used for interconnection when the plug 4 just reaches the socket of the slot 22. That is, the plug 4 is first inserted into the slot 22, and after the power conversion device 2 is pushed for a period of time, each terminal 21 on the power conversion device 2 will be connected to one or more metal bars 3 corresponding to that terminal 21.

[0094] This design method first guides and positions the power conversion device 2 through the cooperation between the insert 4 and the slot 22. After adjusting the position of the power conversion device 2, the terminals 21 of the power conversion device 2 can be accurately connected to the metal busbar 3 in the equipment cabinet 1, which improves the installation efficiency of the power conversion device 2 and reduces the possibility of wear on the terminals 21 caused by the metal busbar 3.

[0095] In some embodiments, the power supply device 100 further includes one or more guide posts 7. Figure 18 for Figure 6 An enlarged view of point B in the middle, and, Figure 18 An exemplary structure of a guide post 7 is shown, wherein each power conversion device 2 includes a guide cylinder 8 disposed away from the mounting port 11. Figure 19 An exemplary structure of a guide cylinder 8 is shown, with reference to Figure 19 Each guide cylinder 8 has a guide hole 81 inside. Figure 18 and Figure 19 In the illustrated embodiment, all guide columns 7 are fixed inside the equipment cabinet 1, and each power conversion device 2 is fixed with a guide cylinder 8.

[0096] In another embodiment, the power supply device 100 further includes one or more guide cylinders 8. Figure 20 An exemplary embodiment shows another structure of guide cylinder 8, in which all guide cylinders 8 are fixed inside the equipment cabinet 1, and each power conversion device 2 includes one or more guide posts 7 disposed opposite to the mounting port 11, wherein, Figure 20 The illustration shows a case where each power conversion device 2 includes a guide post 7.

[0097] During the installation of multiple power conversion devices 2, refer to Figures 18 to 20A guide hole 81 is used for the insertion of a guide post 7. For example, multiple guide holes 81 and multiple guide posts 7 are provided, with each guide hole 81 corresponding to a specific guide post 7. If the guide cylinder 8 is fixed to the power conversion device 2 and the guide post 7 is fixed inside the equipment cabinet 1, then the guide post 7 inside the equipment cabinet 1, after being inserted into the guide cylinder 8 on the power conversion device 2, can play a role in positioning and guiding the power conversion device 2. Similarly, if the guide cylinder 8 is fixed inside the equipment cabinet 1 and the guide post 7 is fixed to the power conversion device 2, then the guide post 7 on the power conversion device 2, after being inserted into the guide cylinder 8 inside the equipment cabinet 1, can also play a role in positioning and guiding the power conversion device 2. Through the cooperation between the guide cylinder 8 and the guide post 7, the installation difficulty of the power conversion device 2 is reduced, the probability of accurate connection between the terminal 21 of the power conversion device 2 and the metal busbar 3 inside the equipment cabinet 1 is increased, the installation efficiency of the power conversion device 2 is improved, and the possibility of wear caused by the metal busbar 3 to the terminal 21 is reduced.

[0098] Furthermore, in one embodiment, with Figure 19 Taking the guide hole 81 shown as an example, the dimension of the guide hole 81 in the width direction (parallel to the X-axis) of the equipment cabinet 1 is larger than its dimension in the height direction (parallel to the Z-axis) of the equipment cabinet 1. That is, the guide hole 81 is an oblong hole, which allows the guide post 7 to have a positional deviation in the width direction of the equipment cabinet 1. In this way, by designing the dimensions of the guide hole 81, the fit between the guide cylinder 8 and the guide post 7 can be used as coarse guidance for the power conversion device 2. That is, the coarse guidance of the power conversion device 2 is first achieved through the fit between multiple guide posts 7 and multiple guide holes 81, and then the precise guidance of the power conversion device 2 is achieved through the fit between the insert 4 and the slot 22.

[0099] When the power conversion device 2 is guided by the cooperation of the guide post 7 and the guide cylinder 8, in order to fully utilize the guiding function of the guide post 7 and the guide cylinder 8, in one embodiment, for each power conversion device 2 (with... Figure 21 Taking another power conversion device 2 as an example, when the end of each guide post 7 facing the corresponding guide hole 81 is located at the opening of the corresponding guide hole 81 facing the guide post 7, that is, when the end of each guide post 7 facing the corresponding guide hole 81 is flush with the opening of the corresponding guide hole 81 facing the guide post 7, for example, Figure 21 The end of the guide post 7 facing the guide hole 81 and Figure 21 When the dashed line L2 is aligned, there is a gap between each slot 22 on the power conversion device 2 and the corresponding insert 4.

[0100] With the above design, during the installation of each power converter 2, when each power converter 2 is pushed into the equipment cabinet 1, there is a gap between the mating insert 4 and the slot 22 when the guide post 7 just reaches the opening of the guide hole 81. That is, the guide post 7 is inserted into the guide hole 81 first, and the insert 4 will only be inserted into the slot 22 after the power converter 2 is pushed for a period of time. Through this design, the coarse guidance of the power converter 2 is achieved first through the cooperation between multiple guide posts 7 and multiple guide holes 81, and then the precise guidance of the power converter 2 is achieved through the cooperation between the insert 4 and the slot 22. The step-by-step guidance, from coarse to precise, achieves graded guidance, gradually adjusting the position of the power converter 2 so that the terminals 21 of the power converter 2 can be accurately connected to the metal busbar 3 in the equipment cabinet 1.

[0101] Furthermore, in one embodiment, for each power converter 2, when the end of each insert 4 facing the mounting port 11 is located in the corresponding slot 22 away from the opening of the mounting port 11, there is a gap between each terminal 21 on the power converter 2 and one or more corresponding metal bars 3 (one or more metal bars 3 that are inserted into the terminal 21) in the equipment cabinet 1. That is, the power converter 2 is first coarsely guided by the cooperation between multiple guide posts 7 and multiple guide holes 81, and then each power converter 2 is pushed into the equipment cabinet 1. Then, the power converter 2 is guided and positioned by the cooperation between the insert 4 and the slot 22. After adjusting the position of the power converter 2, each power converter 2 is pushed into the equipment cabinet 1, and finally each terminal 21 of the power converter 2 is accurately connected to the metal bar 3 in the equipment cabinet 1, which improves the installation efficiency of the power converter 2 and reduces the possibility of wear on the terminal 21 caused by the metal bar 3.

[0102] In some embodiments, return to reference Figure 7 The power supply equipment 100 also includes multiple baffles 9, which are fixed inside the equipment cabinet 1. And refer to... Figure 9 The arrangement of multiple baffles 9 is parallel to the arrangement of multiple power conversion devices 2. The space between two adjacent baffles 9 is used for the insertion or removal of a power conversion device 2. The multiple baffles 9 serve as coarse guides, guiding the power conversion device 2 between two adjacent baffles 9, so that the power conversion device 2 can be pushed into the equipment cabinet 1 according to the expected trajectory under the constraint of the adjacent baffles 9.

[0103] Furthermore, in some embodiments, a reference is returned. Figure 7Each baffle 9 extends along the thickness direction of the equipment cabinet 1, and at least a portion of each baffle 9 is located on the side of one or more inserts 4 facing the mounting opening 11. That is, during the process of pushing the power conversion device 2 into the equipment cabinet 1, each power conversion device 2 first undergoes coarse guiding through the baffles 9 on both sides, and then achieves precise guidance through the cooperation between the inserts 4 and the slots 22. Alternatively, during the process of pushing the power conversion device 2 into the equipment cabinet 1, each power conversion device 2 first undergoes coarse guiding through the baffles 9 on both sides, and then achieves coarse guidance through the cooperation between multiple guide posts 7 and multiple guide holes 81, and finally achieves precise guidance through the cooperation between the inserts 4 and the slots 22. By performing one or more coarse guiding operations followed by precise guidance, the position of the power conversion device 2 is gradually adjusted, allowing the terminals 21 of the power conversion device 2 to be accurately connected to the metal busbars 3 inside the equipment cabinet 1.

[0104] In some embodiments, refer to Figure 4 and Figure 6 Multiple baffles 9 are respectively provided on both sides of the power conversion device 2 in the width direction. That is, on one side of the power conversion device 2 in the width direction (for example, Figure 4 and Figure 6 Multiple baffles 9 are provided on the upper side of the power conversion device 2, and the arrangement direction of the multiple baffles 9 is parallel to the arrangement direction of the multiple power conversion devices 2; and on the other side in the width direction of the power conversion device 2 (for example, Figure 4 and Figure 6 Multiple baffles 9 are also provided on the lower side of the medium power conversion device 2, and the arrangement direction of the multiple baffles 9 is parallel to the arrangement direction of the multiple power conversion devices 2.

[0105] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
