Description

Technical Field

[0001] This application relates to the field of switching power supplies, and more particularly to a hot-swappable power module structure and power supply equipment. Background Technology

[0002] Currently, power modules typically require quick plug-in / plug-out capabilities to save maintenance time. However, during hot-plugging, arcing can easily occur at metal contact points, potentially leading to terminal burnout or safety accidents. Furthermore, most existing solutions employ a sliding mechanical lock, relying on the displacement of the lock's moving parts to achieve mechanical limiting and trigger a signal switch to generate a shutdown signal. This approach depends on the matching accuracy between the module and the cabinet frame, the installation accuracy of the mechanical lock device and the module, and the installation accuracy of the mechanical lock and signal switch. Insufficient accuracy may cause the sliding mechanical lock to fail to reliably limit movement or trigger the signal switch.

[0003] Therefore, ensuring the safe hot-swapping of power modules and preventing the failure to activate signal switches have become technical problems that need to be solved. Summary of the Invention

[0004] This application provides a hot-swappable power module structure to overcome the above-mentioned problems.

[0005] According to this application, a hot-swappable power module structure is provided, including a cabinet, a power module, and a trigger. The power module includes a mounting plate for detachably connecting to the cabinet, and a switch mounted on the mounting plate that controls the power module to switch between a power-on state and a power-off state. The trigger is detachably mounted on the outside of the mounting plate. When the trigger is mounted on the mounting plate, it can trigger the switch to control the power module to switch to a power-on state. When the trigger is separated from the mounting plate, it can trigger the switch to control the power module to switch to a power-off state.

[0006] Preferably, the mounting plate is mounted to the cabinet via a mounting member, and the trigger member includes a shielding portion so as to shield the mounting member when the trigger member is mounted on the mounting plate.

[0007] Preferably, the mounting component includes mounting bolts capable of connecting the mounting plate to the cabinet.

[0008] Preferably, the switch is located on the inner side of the mounting plate.

[0009] Preferably, the trigger includes a bent portion, and the mounting plate has a through hole, through which the bent portion can pass to trigger the switch.

[0010] Preferably, the trigger can be mounted to the mounting plate by a trigger bolt, and the trigger bolt can pass through the mounting plate to trigger the switch.

[0011] According to another aspect of this application, a power supply device is also provided, including the power module hot-swappable structure described above.

[0012] With this application, when the battery module is installed in the rack, a trigger is installed to activate the switch and power the battery module. When the battery module is removed, the trigger is removed first to de-power the battery module, allowing the battery module to be safely hot-swapped. Attached Figure Description

[0013] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention.

Obviously, for those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Elements with the same reference numerals in the drawings are denoted as similar elements. Unless otherwise stated, the figures in the drawings are not to be limited by scale.

[0018] Figure 3 This is a schematic diagram of another hot-swappable battery module structure provided in an embodiment of this application. Detailed Implementation

[0019] To more clearly illustrate the specific implementation methods, technical solutions, and advantages of this application, this document will provide a detailed explanation of the technical solutions in conjunction with the relevant accompanying drawings. It should be noted that the implementation methods mentioned herein represent only some examples, not all. Based on these examples, any other implementation methods that can be deduced by those skilled in the art without innovative work should also be considered as the object of protection of this application.

[0020] This document discloses numerous different implementations or examples to demonstrate the diverse structures of the invention. In describing these specific examples, we have sought to simplify the description, but these examples are not intended to limit the scope of the invention. Furthermore, for consistency and clarity, the same reference numerals and / or letters may be repeated in different examples; such repetition does not imply a direct connection between the different examples or settings.

[0021] In the description, we may use terms describing spatial relative positions, such as "inside," "outside," "middle," "outer," "below," "below," "above," "front," and "back," to describe the relative position or motion state of one component or feature with another. These terms apply not only to the orientation shown in the illustration but also to different orientations that the device may take during use or operation. For example, if the device in the illustration flips, adjusts its posture, or changes its motion, the corresponding orientation indication will also change. For instance, a component originally described as "below other components or features" may become "above other components or features." Therefore, expressions like "below" can actually encompass both "above" and "below." The device may be oriented in different ways (e.g., rotated 90 degrees or in other directions), in which case the spatial relative relationship descriptions used in the text should also be interpreted accordingly.

[0022] According to one aspect of this application, a hot-swappable power module structure is provided, including a cabinet, a power module, and a trigger 100. The power module includes a mounting plate 200 for detachably connecting to the cabinet, and a switch 210 mounted on the mounting plate 200 and capable of controlling the power module to switch between a power-on state and a power-off state. The trigger 100 is detachably mounted on the outside of the mounting plate 200. When the trigger 100 is mounted on the mounting plate 200, it can trigger the switch 210 to control the power module to switch to a power-on state. And when the trigger 100 is separated from the mounting plate 200, it can trigger the switch 210 to control the power module to switch to a power-off state.

[0023] In the technical solution of this application, the mounting plate 200 can be part of the battery module housing. When the battery module is inserted into the slot of the rack, the mounting plate 200 can be fixed to the rack by means of bolting, snap-fitting, etc. The trigger 100 can take an appropriate shape and be installed on the mounting plate 200 in an appropriate form. For example, the trigger 100 can be plate-shaped and can be installed on the mounting plate 200 by bolting, snap-fitting, etc., or it can also be column-shaped, etc. Furthermore, the switch 210 can take the form of, for example, a pressure switch, so that when the trigger 100 is installed on the mounting plate, it can trigger the switch 210. The trigger switch 210 can send an electrical signal to the rack's power system to supply power to the slot. Correspondingly, when the battery module needs to be removed, the trigger 100 is first removed from the mounting plate 200. The trigger 100 is no longer in contact with the switch 210, so that the switch 210 no longer sends a signal to the power system, de-energizing the slot. At this time, the battery module can be safely removed. Alternatively, switch 210 can take other forms, such as being able to send different signals when trigger 100 is in contact with the switch and when it is away from the switch, to control the power system to energize and de-energize the slot.

[0024] To avoid accidental insertion or removal, according to a preferred embodiment, the mounting plate 200 is mounted to the cabinet 300 via a mounting member, and the trigger member 100 includes a shielding portion 102 to shield the mounting member when the trigger member 100 is mounted to the mounting plate 200.

[0025] In the technical solution of this application, the mounting component can be in the form of bolts, quick-release structures, etc., so that when the trigger 100 is installed on the mounting plate 200, the blocking part 102 blocks the mounting component, thereby preventing the power module from being pulled out without removing the trigger 100 and avoiding accidental operation. Preferably, as Figure 1 As shown, the trigger 100 can be sheet-shaped and may include a mounting portion 101 for mounting on the mounting plate 200. The shielding portion 102 can be integrally formed with the mounting portion 101 and bends and extends from the end of the mounting portion 101, so that the shielding portion 102 and the mounting portion 101 are at different heights to avoid the mounting component.

[0026] To ensure a secure installation of the power module and facilitate plugging and unplugging, according to a preferred embodiment, such as... Figure 1 As shown, the mounting component includes mounting bolts 202 capable of connecting the mounting plate 200 to the cabinet 300.

[0027] To reduce the size of the battery module, according to a preferred embodiment, such as... Figure 1 As shown, the switch 210 is disposed on the inner side of the mounting plate 200.

[0028] In the technical solution of this application, the switch can be disposed inside the housing of the battery module. The trigger 100 can contact the switch 210 by opening a through hole in the mounting plate 200 or by means of a transmission mechanism, so as not to affect the triggering effect of the switch 210.

[0029] According to a preferred embodiment, such as Figure 1 and Figure 2 As shown, the trigger 100 includes a bent portion 103, and the mounting plate 200 has a through hole 201. The bent portion 103 can pass through the through hole 201 to trigger the switch 210.

[0030] In the technical solution of this application, the trigger 100 can be installed on the mounting plate 200 by bolts 104. After installation, the bent portion 103 passes through the through hole 201 and abuts against the trigger piece 211 of the switch 210. The bent portion 103 applies pressure to the trigger piece 211, causing the trigger piece 211 to press against the switch contacts, thereby putting the switch 210 into the ON state. At this time, the switch 210 can transmit an electrical signal to the power supply system of the cabinet to power on the installed power module. Correspondingly, when the trigger 100 is removed from the mounting plate 200, the bent portion 103 no longer abuts against the switch 210, so the switch 210 stops sending electrical signals to the power supply system, and the power module enters the OFF state. At this time, the power module can be safely unplugged.

[0031] According to another preferred embodiment, such as Figure 3 As shown, the trigger 100 can be mounted on the mounting plate 200 by a trigger bolt 104, and the trigger bolt 104 can pass through the mounting plate 200 to trigger the switch 210.

[0032] This implementation method and Figure 1 Unlike other switches, the bolt 104 used to mount the trigger 100 can directly act on the trigger piece 211 of the switch 210 to achieve the same effect.

[0033] According to another aspect of this application, a power supply device is also proposed, including the power module hot-swappable structure described above.

[0034] In the technical solution of this application, the power supply equipment may include a cabinet with multiple slots and a battery unit that can be inserted into the slots. With this application, when the battery module is installed in the cabinet, a trigger is installed to trigger the switch to power on the battery module. When the battery module is removed, the trigger is removed first to de-power the battery module, so that the battery module can be safely hot-swapped.
