Description

Technical Field

[0001] This utility model relates to the field of new energy technology, specifically to a novel modular battery pack structure with a split universal bracket. Background Technology

[0002] Traditional lithium battery packs mostly adopt a "module-based" structure. This structure suffers from low space utilization due to the redundancy of the modules themselves, limiting the improvement of battery pack energy density. To address this issue, a "module-less" battery pack solution has been proposed, which can effectively improve pack energy density. However, existing module-less mounting brackets are mostly "integral" designs, which are difficult to develop, require high initial mold investment, and have complex component manufacturing processes, resulting in high manufacturing costs. More importantly, integrated brackets have extremely poor adaptability. For battery packs with different cell numbers and sizes, custom molds must be redesigned and manufactured, extending the R&D cycle, failing to flexibly meet diverse market demands, and increasing mold maintenance costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a novel modular battery pack structure with a split universal bracket, which has the advantage of reducing battery pack costs and solves the problems of high mold opening costs and high component costs.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A novel modular battery pack structure with a split universal bracket includes a battery housing containing multiple sets of battery cells arranged in an array inside the battery housing. The battery housing is provided with a universal bracket for positioning each set of battery cells. The universal bracket is a split structure with multiple independently detachable units, used to assemble and support the battery cells to achieve a modular battery pack structure.

[0005] Preferably, the pressure strip is fixed to the battery casing and the universal bracket by locking screws, and works with the universal bracket to limit and fix the battery cell.

[0006] Preferably, an overcurrent electrode is connected to the terminal of the battery cell to achieve electrical connection between multiple battery cells.

[0007] Preferably, a buffer foam is provided between the universal bracket and the battery cell, and a buffer foam is also provided between the battery cell and the pressure strip, in order to buffer the vibration and impact generated when the battery cell is working.

[0008] Preferably, the pressure strip is arranged along the arrangement direction of the battery cells, and the surface of the pressure strip that contacts the battery cells conforms to the outer contour of the battery cells.

[0009] By employing the above technical solution, this utility model provides a novel modular battery pack structure with a split universal bracket, which has at least the following beneficial effects: 1. The modular battery pack structure of this new type of split universal bracket can accurately position and support each array of battery cells, solving the problem that traditional integral brackets are difficult to adapt to different numbers and sizes of battery cells. This greatly improves the versatility of the bracket, eliminates the need to design molds separately for battery packs of different specifications, and significantly reduces production and modification costs.

[0010] 2. The moduleless battery pack structure of this new type of split universal bracket has buffer foam on the contact surfaces between the universal bracket and the battery cell, and between the battery cell and the pressure bar, forming a two-way wrapping buffer system. This system can fully absorb the vibration and impact energy brought by the operation of the battery cell and the external environment, avoid direct collision between the battery cell and rigid components, and reduce the risk of wear on the battery cell shell and damage to the internal structure.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a novel modular battery pack structure for a split universal bracket.

[0015] Example 1: Combination Figures 1-4As shown, this utility model provides a novel modular battery pack structure with a split universal bracket, including a battery housing 3. Multiple battery cells 5 are housed within the battery housing 3, arranged in an array inside the battery housing 3. A universal bracket 1 is provided within the battery housing 3 for positioning each battery cell 5. The universal bracket 1 is a split structure with multiple independently detachable units, used to assemble and support the battery cells 5, thereby achieving a modular battery pack structure. It can accurately position and support each array of battery cells 5, solving the problem that traditional integral brackets are difficult to adapt to different numbers and sizes of battery cells 5, significantly improving the versatility of the bracket. It eliminates the need to design separate molds for different battery pack specifications, significantly reducing production and modification costs.

[0016] This makes the installation, disassembly, and maintenance of cell 5 more convenient. When a single cell 5 has a problem, only the bracket of the corresponding unit needs to be replaced, without disassembling the entire battery pack, which reduces the workload and time cost of maintenance.

[0017] Specifically, the terminal of cell 5 is connected to an overcurrent electrode 4, which is used to realize the electrical connection between multiple cells 5. Compared with traditional wire connection or flexible connection, the rigid structure of the overcurrent electrode 4 can ensure a tighter and more stable contact between cells 5, reduce contact resistance, reduce energy loss and heat generation risk during current transmission, and improve the electrical performance stability of the battery pack.

[0018] As can be seen from the embodiments, this structure achieves lightweighting and improved space utilization through a split bracket, while significantly reducing mold and component costs, which is conducive to improving economic and technical benefits.

[0019] Example 2: Combination Figure 3 and Figure 4 As shown, based on Embodiment 1, the pressure strip 2 is fixed to the battery housing 3 and the universal bracket 1 by the locking screw 7. It works with the universal bracket 1 to limit and fix the battery cell 5, which greatly improves the connection rigidity between the pressure strip 2 and the bracket. It can effectively resist complex working conditions such as vibration and impact, prevent the battery cell 5 from shifting or loosening, and ensure the structural stability of the battery pack.

[0020] Specifically, a buffer foam 6 is provided between the general bracket 1 and the battery cell 5, and a buffer foam 6 is also provided between the battery cell 5 and the pressure strip 2. These buffer foams are used to buffer the vibration and impact generated when the battery cell 5 is working. Buffer foam 6 is provided on the contact surfaces of the general bracket 1 and the battery cell 5, and the battery cell 5 and the pressure strip 2, forming a two-way wrapping buffer system. This system can fully absorb the vibration and impact energy brought by the operation of the battery cell 5 and the external environment, avoid direct collision between the battery cell 5 and rigid components, and reduce the risk of wear on the outer shell and damage to the internal structure of the battery cell 5.

[0021] Furthermore, the pressure strip 2 is arranged along the arrangement direction of the battery cell 5, and the surface of the pressure strip 2 that contacts the battery cell 5 conforms to the outline of the battery cell 5. This allows for the one-time positioning and fixing of the entire row of battery cells 5. Compared with the design of a single battery cell 5 corresponding to an independent pressure strip 2, this reduces the number of pressure strips 2 used and the assembly process, simplifies the internal structure of the battery pack, and significantly improves assembly efficiency.

[0022] As can be seen from the above embodiments: First, multiple sets of battery cells 5 are arranged in an array and installed inside the battery casing 3. Then, each unit of the split universal bracket 1 is installed corresponding to the position of each set of battery cells 5. Each set of battery cells 5 is precisely positioned and supported to form the main structure of the moduleless battery pack. Then, the current-carrying electrode 4 is connected to the terminal post of the battery cell 5 to realize the electrical connection between multiple battery cells 5. Next, buffer foam 6 is installed on the contact surface between the universal bracket 1 and the battery cell 5, and the contact surface between the battery cell 5 and the pressure strip 2 to construct a "two-way wrapping" buffer system. Then, the pressure strip 2 is placed along the arrangement direction of the battery cells 5 and the surface of the pressure strip 2 in contact with the battery cell 5 is made to fit the outline of the battery cell 5. Finally, the pressure strip 2 is fixed to the battery casing 3 and the universal bracket 1 by the locking screw 7, and works with the universal bracket 1 to complete the limiting and fixing of the battery cell 5. Finally, the overall assembly of the moduleless battery pack of the new split universal bracket 1 is completed.

[0023] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
