Description

Technical Field

[0001] The invention relates to a module hot-swap structure, in particular to a DCDC module hot-swap structure for reusing retired batteries. Background Art

[0002] With the development of new energy vehicles, retired batteries that have exceeded their shelf life will become a new problem. Due to their poor consistency, they can no longer be used as power batteries for cars. We use these retired batteries as charging pile batteries and need to make a DCDC module that supports hot plugging. Therefore, we need to design a hot plug structure based on our existing conditions. In the existing technology, the hot plug structure is made into a drawer mode. The module is equivalent to a drawer. There will be a bracket to fix the module. This bracket is made into a slide rail mode, which is equivalent to a track. A plug is provided at one end of the module (push and pull direction), and a socket is provided at one end of the track. The plug and the socket correspond in position. During the push and pull of the module, the connection and disconnection of the plug and the socket are realized, thereby realizing the hot plug function. In the current technology, in order to ensure the precise positioning of the module, a guide hole is provided on the socket, and a guide head is provided at the corresponding position on the plug. The socket corresponds in position. During the push and pull of the module, the connection and disconnection of the plug and the socket are realized, thereby realizing the hot plug function. In the current technology, in order to ensure the precise positioning of the module, a guide hole is provided on the socket, and a guide head is provided at the corresponding position on the plug. The socket corresponds in position. During the push and pull of the module, the connection and disconnection of the plug and the socket are realized, thereby realizing the hot plug function.

[0003] There are two main problems in the existing technical solutions. First, the positioning problem of the plug and the socket. In actual production, there is a deviation between the module chassis. The plug is welded on the module, and there will be deviations during the welding process. Finally, the deviation range in manual assembly is even greater. The existing solution cannot solve this problem, which will cause the plug and the socket to fail to match during the hot plugging process of the module, increasing the scrap rate of the product. Moreover, this scrap situation can only be discovered after it is fully assembled, and a lot of manpower, financial resources and resources have been wasted at this time. The guide head and guide hole set on the plug and the socket can only ensure that the pin in the plug can accurately match the jack in the socket, but cannot ensure the matching of the plug and the socket; second, the problem of fixing the module. In the existing technology, one end of the module is fixed by the matching of the plug and the socket, and the other end is fixed by screws. This fixing method will result in that every time hot plugging is required, the screws need to be unscrewed first, and then hot plugging is performed, which is a cumbersome process; in addition, this fixing method has special requirements for the cabinet, which requires the cabinet to have a rack for fixing the module, and is not suitable for general cabinets.

[0004] After searching, the Chinese patent publication number CN202712595U discloses a modular UPS hot-swap structure, including a female plug-in seat on the rear end face of the plug-in module, a male plug-in seat corresponding to the female plug-in seat at the rear end of each plug-in module grid layer of the UPS rack, guide rails on both sides of each plug-in module grid layer of the UPS rack, a trapezoidal guide hole is provided on one side of at least one vertex of the female plug-in seat, and a trapezoidal guide column corresponding to the trapezoidal guide hole is provided on one side of the male plug-in seat at the rear end of each plug-in module grid layer of the UPS rack. The invention does not require the guide column added to the rear end of the plug-in module and the guide hole added to the rear end of the UPS rack for positioning. The general processing accuracy can meet the accuracy of the guide. The guide holes and guide columns of the male and female plug-in seats themselves can be smoothly docked, reducing the difficulty of production and saving production costs. It also has the advantages of easy processing, simple operation, fast plug-in and pull-out, accurate positioning, precise kissing, and not easy to damage. However, it is aimed at modular UPS rather than DCDC module hot-swap structure, which is not suitable for the requirements of the present invention. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the prior art and provide a DCDC module hot-swap structure for reusing retired batteries.

By moving the DCDC module, the connection and disconnection between the plug and the socket are realized, thereby realizing a hot-swap function. When the plug is connected to the socket, the DCDC module is fixedly connected to the guide rail.

[0008] The hot-swap structure also includes an adjustment plate. The vertical surfaces of the adjustment plate and the guide rail are both provided with openings at positions corresponding to the plug.

[0011] Preferably, the waist-shaped holes of the guide rail are opened in the horizontal direction, and the waist-shaped holes of the adjustment plate are opened in the vertical direction.

[0012] Preferably, a guide rail latch hole is provided at one end of the guide rail in the horizontal direction, and a module latch hole is provided on the DCDC module near the guide rail. The guide rail latch hole and the module latch hole are the same in size and shape. When the plug is inserted into the socket, the guide rail latch hole and the module latch hole are aligned, and the DCDC module is fixed by inserting the latch.

[0016] Preferably, a guide rail heat dissipation hole is provided on the vertical surface of the guide rail, and a chassis heat dissipation hole is provided on the chassis.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. Use two waist-shaped holes (one horizontal and one vertical) to accurately locate the position of the plug. When producing and assembling the hot-swap structure, no particularly high precision is required, which reduces the scrap rate of the product and improves production efficiency.

[0019] 2. The DCDC module is conveniently fixed by the combination of rails and latches. When disassembling, there is no need to remove the screws, only to pull open the latch, which is more convenient, simple and reliable. BRIEF DESCRIPTION OF THE DRAWINGS
