Abstract
Description
Technical Field
[0001] This utility model relates to the field of adapter bracket technology, specifically an automotive battery pack BMS adapter bracket. Background Technology
[0002] Battery packs are typically housed within a battery pack housing, which also houses a Battery Management System (BMS) for managing the battery packs. However, space within the battery pack housing is limited, and the BMS is usually arranged longitudinally with the battery packs. This arrangement significantly encroaches on the effective installation space for the batteries within the battery pack housing, reducing the effective number of battery packs that can be installed within the housing.
[0003] A search revealed that patent application CN219017818U discloses an automotive battery pack BMS adapter bracket, comprising a BMS, multiple battery pack modules, a bracket body, a battery pack housing, and a snap-fit mechanism. The snap-fit mechanism includes four snap-fit connectors, two compression units, multiple springs, a base plate, and a fixing body. The four snap-fit connectors are fixedly connected to their respective compression units, the two compression units are movably connected to the fixing body, and the two ends of the multiple springs are fixedly connected to their respective compression units. This allows the BMS to be installed via the compression units and snap-fit connectors, reducing installation time.
[0004] However, due to the installation via the extrusion unit and the snap-fit connector, the snap-fit connector has poor stability and poor installation effect. At the same time, because the vehicle vibrates when it is in motion, the BMS and the bracket body will vibrate along with it, resulting in low shock absorption performance.
[0005] Therefore, we propose an automotive battery pack BMS adapter bracket. Utility Model Content

Four sets of threaded rods with opposite positions are fixedly installed on the top surface of the partition plate. Four sets of positioning holes with matching positions and specifications are opened on the top surface of the bracket plate. Nuts with matching specifications are fitted on the threaded rods. A mounting groove is opened on the top surface of the bracket plate. A BMS body is fitted on the top surface of the bracket plate.

Four sets of mounting holes A with opposite positions are opened on the top surface of the mounting plate. Four sets of mounting holes B are opened on the bottom surface of the mounting groove.
[0009] The outer wall of the mounting groove is fitted with a rubber layer of the same specification. Four sets of opposing limiting blocks are fixedly installed on the top surface of the partition. The limiting blocks are in contact with the outer wall of the bracket plate. A washer of the same specification is fitted between the nut and the bracket plate.
[0010] Preferably, the top surface of the bracket plate has evenly distributed wire holes, which facilitates the connection of the adapter bracket wires.
[0011] Preferably, the top surface of the BMS body is equipped with heat dissipation fins, which can improve the heat dissipation effect of the BMS body.
[0012] Preferably, the top surface of the support plate has four sets of weight-reducing grooves in opposite positions, which can reduce the weight of the support plate.
