Description

Technical Field

[0001] This utility model relates to the field of battery box technology, and in particular to a vertical mounting structure for a BMS. Background Technology

[0002] A battery enclosure typically includes a battery box that houses the batteries and an electrical box that houses the electrical components. A BMS (Battery Management System) is a device used for intelligent management and maintenance of battery cells. Its main purpose is to prevent overcharging and over-discharging of batteries, extend battery life, and monitor battery status. It is an indispensable and important component of a battery pack and is usually installed inside the electrical box.

[0003] Existing BMS main installation methods: (See reference) Figure 1 The installation method involves directly mounting the BMS onto the enclosure. The disadvantages are as follows: 1. During product assembly, the confined space inside the battery enclosure makes installation inconvenient and time-consuming. 2. Furthermore, since charging / discharging power cables, relays, and other control components are generally located at the top, the BMS is positioned at the bottom. After the product is put into use, when the BMS needs maintenance or replacement, other components obstructing the wrench's operating space must be removed before the BMS can be disassembled, which is extremely detrimental to after-sales service. The BMS wiring port installed at the back of the enclosure is horizontal, meaning operators can only see the side of the port and not its internal cavity. Connecting other wiring harnesses to the BMS port requires "blind insertion," resulting in low assembly efficiency and potential damage to connectors. Similarly, after-sales maintenance, testing, and BMS replacement involve time-consuming and labor-intensive disassembly of numerous surrounding parts and difficulties in plugging and unplugging wiring harnesses connected to the BMS. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of difficulty in wiring, assembly and maintenance caused by unreasonable BMS installation in the prior art, and to propose a vertical installation structure for BMS.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vertical installation structure for a BMS includes an electrical box, a connecting component, and a mounting base. The mounting base is fixed to the inner wall of the electrical box. The connecting component is fixedly assembled with the BMS body. The connecting component and the mounting base are detachably fixed. After assembly, the BMS body is vertically positioned with the plug-in interface facing upwards.

[0007] The angle between the BMS body and the vertical plane ranges from 0° to 60°.

[0008] The mounting base is connected to the connecting assembly by bolts, and the bolts are arranged vertically.

[0009] The connecting assembly includes a plate portion, which has a first bent portion bent along a vertical axis and a second bent portion bent along a horizontal axis. The BMS body is fixedly assembled with the plate portion, and the second bent portion is fixedly assembled with the mounting base by bolts.

[0010] The second bent portion has a vertically arranged through hole. The mounting base includes a sheet metal frame and a nut welded to the sheet metal frame. The nut's axis is vertically arranged. The second bent portion is supported on the mounting base, and a bolt passes through the through hole and is threadedly connected to the nut.

[0011] The plate body is welded or riveted with a threaded rod, which is perpendicular to the plate body. The BMS body has several lugs, and the threaded rod passes through the lugs and is connected to a nut.

[0012] This invention proposes a vertical installation structure for a BMS (Battery Management System), which offers the following advantages: By installing a mounting base on the inner side wall of the electrical box and using connecting components to vertically install the BMS body, the BMS body's connectors face upwards. This structure not only facilitates insertion operations within a limited space, improving assembly efficiency, but also avoids the operational inconvenience caused by space constraints in traditional structures. Furthermore, the BMS body is detachably fixed to the mounting base via connecting components; when maintenance or replacement is required, only a few bolts need to be removed, greatly improving the convenience of later maintenance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 2-5 A vertical installation structure for a BMS includes an electrical box 11, a connecting component 2, and a mounting base 3. The mounting base 3 is fixedly connected to the inner wall of the electrical box 11. The connecting component 2 is fixedly assembled with the BMS body 1. The connecting component 2 and the mounting base 3 are detachably fixed. After assembly, the BMS body 1 is vertically positioned with the plug-in interface facing upward.

[0021] Mounting base 3 is fixed to the inner wall of electrical box 11 to provide a stable mounting base. Connecting assembly 2 is used to secure the BMS body 1 and is detachably fixed to mounting base 3 by bolts. After assembly, the BMS body 1 is reliably supported on connecting assembly 2 and remains vertically oriented with its connectors facing upwards. This allows the operator to directly see the connectors of the BMS body 1 when making electrical connections, avoiding blind insertion.

[0022] This invention utilizes a mounting base 3 on the inner wall of the electrical box 11 and a connecting component 2 to vertically mount the BMS body 1, ensuring the BMS body 1's connectors face upwards. This structure not only facilitates insertion operations within a limited space, improving assembly efficiency, but also avoids the operational inconvenience caused by space constraints in traditional structures. Furthermore, the BMS body 1 is detachably fixed to the mounting base 3 via the connecting component 2, allowing for easy maintenance or replacement with only a few bolts removed, significantly enhancing the convenience of future maintenance.

[0023] Optionally, the angle between the BMS body 1 and the vertical plane can range from 0° to 60°. As one implementation method, a vertical installation is adopted, that is, the angle between the BMS body 1 and the vertical plane is 0°, but it can also be 89°.

[0024] Mounting base 3 and connecting assembly 2 are connected by bolts, with the bolts arranged vertically. Connecting assembly 2 includes a plate body 4, which has a first bent portion 5 bent along a vertical axis and a second bent portion 8 bent along a horizontal axis. BMS body 1 is fixedly assembled with plate body 4, and the second bent portion 8 is fixedly assembled with mounting base 3 by bolts. The second bent portion 8 has a vertically arranged through hole. Mounting base 3 includes a sheet metal frame 10 and a nut 9 welded to the sheet metal frame 10. The axis of nut 9 is vertically arranged. The second bent portion 8 is supported on mounting base 3, and the bolts pass through the through hole and are threadedly connected to nut 9.

[0025] Mounting base 3 and connecting assembly 2 are connected by bolts, with the bolts arranged vertically. Connecting assembly 2 includes a plate portion 4, which is bent along a vertical axis to form a first bent portion 5. The first bent portion 5 is further bent along a horizontal axis to form a second bent portion 8. BMS body 1 is fixed to plate portion 4, providing stable support. The second bent portion 8 has a vertical through hole for assembly with mounting base 3. Mounting base 3 consists of a sheet metal frame 10 and a nut 9 welded to the sheet metal frame 10, with the axis of the nut 9 being vertical. The second bent portion 8 is supported on mounting base 3, and bolts pass through the through hole and are threadedly connected to the nut 9, thereby securely mounting BMS body 1 inside electrical box 11 via connecting assembly 2.

[0026] The bending design of the plate part 4, the first bending part 5, and the second bending part 8 allows the connecting component 2 to be reliably fixed vertically to the mounting base 3. The BMS main body 1 is vertically positioned and uses bolts for quick assembly and disassembly. This facilitates direct visual operation of the interface by operators, avoiding blind insertion and improving assembly efficiency. Furthermore, it allows for easy maintenance or replacement of the BMS main body 1 by simply loosening the bolts, reducing the need to disassemble surrounding components and improving maintenance convenience and product versatility.

[0027] The plate body 4 is welded or riveted with a threaded rod 6, which is perpendicular to the plate body 4. The BMS main body 1 has several ears 7, and the threaded rod 6 passes through the ears 7 and is connected to a nut.

[0028] A threaded rod 6 is welded or riveted onto the plate body 4. The threaded rod 6 is arranged perpendicularly to the plate body 4 and provides a fixing point for the BMS main body 1. The BMS main body 1 has several ears 7, each with a through hole. The threaded rod 6 passes through each ear 7 sequentially and is connected to a nut at its end. Through the locking action of the nut, the BMS main body 1 can be firmly fixed to the plate body 4, thereby preventing loosening or displacement due to vibration during operation. By setting the threaded rod 6 on the plate body 4 and having the threaded rod 6 pass through the ears 7 of the BMS main body 1 and then be fixed by the nut, not only is a stable integral structure formed between the BMS main body 1 and the connecting assembly 2, but the assembly process is also simple, requiring only the ears 7 to be inserted sequentially and the nut to be tightened. This design improves the fixing reliability of the BMS main body 1, reduces additional fasteners and complex processes, thereby reducing production costs and improving assembly and maintenance efficiency.

[0029] The electrical box 11 of this device has a mounting base 3 fixedly attached to its inner wall. The mounting base 3 consists of a sheet metal frame 10 and a nut 9 welded to the sheet metal frame 10, with the axis of the nut 9 vertically oriented. The connecting assembly 2 is detachably fixed to the mounting base 3 by bolts. The bolts pass vertically through the through holes on the second bend 8 and are threadedly connected to the nut 9, so that the connecting assembly 2 is stably supported on the mounting base 3. The connecting assembly 2 includes a plate body 4, which is bent along the vertical axis to form a first bend 5, and the first bend 5 is then bent along the horizontal axis to form a second bend 8. The BMS body 1 is fixedly assembled on the plate body 4. Threaded rods 6 are welded or riveted onto the plate body 4. The threaded rods 6 are arranged perpendicular to the plate body 4 and pass through the ears 7 of the BMS body 1 in sequence, and are then locked by nuts, so that the BMS body 1 is firmly fixed to the plate body 4. After assembly, the BMS body 1 is vertically positioned inside the electrical box 11 with the plug-in interface facing upwards, enabling direct and visible plug-in of external electrical connectors.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
