Description

Technical Field

[0001] This utility model belongs to the technical field of battery box structural accessories, and in particular relates to a BMS modular bracket fixing structure. Background Technology

[0002] A multifunctional modular BMS bracket designed to address space limitations in existing battery systems can be used as a BMS bracket to fix the BMS, as well as for structural fixation, and it also facilitates installation and subsequent BMS maintenance.

[0003] Most BMS (Battery Management Systems) are directly fixed to the module endplate. Due to the limited space, they cannot be directly installed using tools during production and installation; they must be pre-installed on the module endplate. The battery box is a box structure consisting of a liquid cooling plate and a protective shell, with internal supports for arranging and installing block-shaped lithium batteries. The BMS is roughly the size and shape of a battery block, and the internal space of the battery box is insufficient for laying the BMS flat, which is very inconvenient. Subsequent maintenance of the BMS also requires removing the module endplate and other structurally connected components to retrieve it, causing significant trouble for subsequent maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a modular support structure for BMS, which allows the BMS to be removed by disassembling the module end plate and other structurally connected components, thus solving the problem of cumbersome maintenance.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A modular bracket fixing structure for a battery management system includes a bracket installed inside the battery box, the bracket being located at the end of the battery pack;

[0007] The bracket is a shell structure with a U-shaped side projection, forming a mounting slot for installing the BMS module. Mounting plates are provided on both sides of the bracket, and mounting holes are provided.

[0008] A clamping frame is provided in the mounting slot. The side projection of the clamping frame is L-shaped. It is fixed to the side wall of the mounting slot and forms a clamping groove for clamping the BMS module.

[0009] Includes a cover on the upper opening side of the mounting bracket, the cover being installable in an openable manner to form lateral support for the side walls of the mounting groove.

[0010] Furthermore, the clamping frame has a rolled-up portion corresponding to the opening side, forming a flared side. The side wall of the clamping frame has a first heat dissipation hole, which is a strip-shaped groove.

[0011] Furthermore, the bracket has a second heat dissipation hole on the side wall corresponding to the BMS module. The second heat dissipation hole is a strip-shaped groove, and the two sides of the second heat dissipation hole are arc-shaped and rolled up to form heat dissipation fins. One side of the cover is hinged to the bracket, and the other side has a folded edge. The folded edge is concave to form a slot, and the corresponding side of the bracket is bent to form a retaining strip for engaging with the slot. The cover has multiple wire grooves on the engaging side, and the bottom of the wire grooves is arc-shaped and fitted with silicone rings.

[0012] The present invention has the following advantages: The present invention adopts an independent modular BMS fixing bracket, which fixes the BMS to the structural reinforcement with screws, thereby achieving the function of structural fixation. In subsequent maintenance, the BMS can be removed simply by removing the screws from the top, which greatly facilitates subsequent maintenance. Attached Figure Description

Detailed Implementation

[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] like Figures 1-4 As shown: A BMS modular bracket fixing structure includes a bracket installed inside the battery box, the bracket 1 being located at the end of the battery pack; block-shaped batteries are arranged and installed to form a battery pack, the entire battery pack is placed in the battery box, and a certain space is reserved at the end for placing the BMS module.

[0021] The bracket 1 is a shell structure with a U-shaped side projection. The bracket has two side walls and a bottom. The two side walls are parallel to each other and are vertically and integrally connected to the base plate. The bottom serves as a bottom support, and the corresponding opening slot faces upward to form a mounting slot 11 for installing the BMS module 3. Mounting plates 12 are provided on both sides of the bracket 1, and mounting holes are provided. The mounting plates are formed by vertical folds on the free sides of the two side walls of the bracket, forming an overlapping part for overlapping with the battery rack end plate. They are fixed by mounting holes and screws.

[0022] A clamping frame 2 is provided in the mounting slot 11. The side projection of the clamping frame 2 is L-shaped. It is fixed to the side wall of the mounting slot 11 and forms a clamping groove for clamping the BMS module 3. The bottom of the clamping frame is fixed to the side wall of the mounting slot to clamp and fix the BMS module, preventing the BMS module from shaking and affecting the stability of the wiring. The clamping frame is made of stainless steel and has a certain degree of toughness. The width of the clamping groove is matched with the thickness of the BMS module. By bending the clamping frame with external force, the opening side of the clamping frame is expanded, making it easier to place the BMS module. Then, the clamping frame retracts by its own elasticity to fix the BMS module, making installation and removal convenient.

[0023] The mounting bracket 1 includes a cover 4 on the open side of the mounting bracket. The cover 4 can be opened and installed to form lateral support for the side walls of the mounting groove 11. The cover is used to form a bottom seal for the bracket, and more importantly, to form lateral support on both sides of the bracket. The bracket is a shell structure and is installed at the end of the battery box, between the box and the battery pack. Without the support of the cover, the bracket is prone to deformation under the pressure of the battery pack.

[0024] like Figure 1 As shown: The clamping frame 2 has a rolled-up portion corresponding to the opening side, forming a flared side. This allows the BMS module to be easily inserted without bending the clamping frame. The side wall of the clamping frame 2 has a first heat dissipation hole 21, which is a strip-shaped groove. This is used for heat dissipation on one side of the BMS module.

[0025] like Figure 2 As shown: A second heat dissipation hole 13 is provided on the side wall of the bracket 1 corresponding to the side wall of the BMS module 3. The second heat dissipation hole 13 is a strip-shaped groove, and the two sides of the second heat dissipation hole 13 are arc-shaped and rolled up to form heat sinks 14. The side wall of the bracket is linearly cut, and then the second heat dissipation hole is formed by stamping. After stamping, the body part of the side wall of the bracket forms a heat sink for heat dissipation on the other side of the BMS module. At the same time, after the side wall of the bracket absorbs heat, it quickly dissipates heat through the heat sink.

[0026] The cover 4 is hinged to the bracket 1 on one side, and has a folded edge 41 on the other side. The folded edge 41 is recessed to form a slot 42. The bracket 1 is bent on the corresponding side to form a retaining strip 15, which is used to cooperate with the slot 42. The folded edge is formed by bending the free side of the cover at 90°. It is fixed by engaging with the retaining strip through the slot, which improves the stability of the cover installation. At the same time, the cover can be opened by flipping it over, which improves convenience. The cover 4 has multiple wire grooves 43 on the corresponding engaging side. The bottom of the wire grooves 43 is arc-shaped and a silicone ring 44 is installed. The wire grooves are open slot structures on the folded edge side, which are used as wire grooves for data cable installation. Multiple wire grooves can organize the wiring, which is convenient for inspection and maintenance. The silicone ring can fix the data cable through contraction, which makes it stable.

[0027] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
