Description

Technical Field

[0001] This utility model relates to the field of lithium battery installation technology, and in particular to an integrated lithium battery installation structure. Background Technology

[0002] Lithium batteries are used in energy storage devices, power tools and various electronic products due to their high energy density and long cycle life. In practical applications, multiple individual lithium batteries need to be combined into battery packs with specific voltages and capacities to meet the power supply needs of different devices.

[0003] Existing battery pack mounting structures use housings or brackets to fix and store multiple batteries. While this design can achieve basic storage functionality, the structure is customized for a specific capacity and lacks standardized interfaces.

[0004] When a larger capacity battery system is required, users can only place multiple independent battery packs side by side. Because these independent battery packs lack a standardized structure for interconnection, they can only be loosely stacked or arranged, and cannot form a stable and reliable whole. This not only makes the installation process cumbersome, but also results in poor overall integrity of the combined battery array, weak vibration resistance, and difficulty in meeting the application scenarios with higher requirements.

[0005] Therefore, this utility model proposes an integrated lithium battery mounting structure to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing integrated lithium battery mounting structures, such as structural dispersion, difficulty in standardized splicing and expansion, and poor overall structural stability after assembly, this utility model aims to provide an integrated lithium battery mounting structure with improved structure that can effectively solve the above problems.

[0007] This utility model provides an integrated lithium battery mounting structure, including a bracket, a housing, multiple cylinders and multiple fixing posts disposed inside the housing, multiple limiting posts disposed on the top of the bracket, a PCB board covering the top of the housing, and multiple screws.

[0008] The box serves as a housing unit, and multiple cylinders and multiple fixing posts for housing batteries are fixedly connected inside the box.

[0009] Furthermore, the top of the bracket is fixedly connected with multiple limiting posts. During assembly, the box is installed on the top of the bracket, and the top of the limiting posts and the bottom of the fixed posts are engaged to achieve positioning. Finally, the PCB board is covered on the top of the box and is threadedly connected to the fixed posts by screws passing through holes in the PCB board, thereby firmly integrating the box, PCB board and bracket into an inseparable whole structure.

[0010] Preferably, the storage mechanism further includes multiple rubber pads, which are slidably connected to the inside of the cylinder. This arrangement not only provides cushioning and vibration reduction protection for the battery, but also uses the friction of the rubber material to prevent the battery from shaking or rotating unnecessarily inside the cylinder, ensuring positional stability.

[0011] Preferably, the bottom of each of the plurality of cylinders is fixedly connected with a plurality of reinforcing ribs. The reinforcing ribs, as a structural reinforcement design, can improve the structural strength and rigidity of the bottom of the cylinders, ensuring that they are not easily deformed when subjected to the weight of the battery or external impact.

[0012] Preferably, the multiple cylinders are arranged in a rectangular array inside the housing. This regular layout helps to maximize the use of the internal space of the housing, achieve high-density battery integration, and also facilitates the standardized design of subsequent circuits on the PCB board.

[0013] Preferably, the integrated lithium battery mounting structure further includes two terminals on one side of the bracket and a connecting plate electrically connected to the bottom of the PCB board. After the internal battery circuit is gathered by the connecting plate, one end of the connecting plate is connected to the top of the two terminals, thereby constructing a complete electrical path from the battery to the outside and forming standardized positive and negative output terminals.

[0014] Preferably, the structure further includes a metal washer and a terminal nut. The bottom of each of the multiple terminals passes through the center hole of the metal washer in sequence and is threaded with a terminal nut. This crimping structure can provide a larger area and more reliable contact interface for the external cable, and a firm lock can be achieved by tightening the terminal nut.

[0015] Preferably, the mounting mechanism further includes a metal frame and a second screw. The metal frame is detachably threaded to one corner of the bracket by the second screw. This metal frame is the core component for realizing modular expansion. It can be used as a connection interface to fix a single module to other devices, or as a splicing interface to connect the metal frames of other modules.

[0016] Preferably, both outer surfaces of the metal frame are square. This specific geometry ensures that the installation interfaces between different modules have uniform size and shape, whether installed vertically or horizontally, thus guaranteeing the convenience, versatility, and structural regularity of modular assembly.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem of the difficulty in standardizing and modularizing battery packs in the prior art by setting a metal frame that can be connected by screws at the corner of the bracket, which allows multiple installation structural units to be easily aligned and spliced ​​into an array. This improves installation flexibility and allows users to quickly combine battery capacity according to their needs.

[0018] 2. This utility model solves the problems of insufficient battery protection, easy shaking, and unstable overall installation in the prior art by setting a cylinder with a rubber pad inside the box and using a combination of limiting post engagement and screw fastening between the bracket and the box. It achieves both buffering and vibration reduction to protect the battery and multi-point firm locking, thereby improving the structural stability and impact resistance of the entire device.

[0019] 3. This utility model solves the problems of scattered functional components, complex assembly, and large space occupation of battery packs in the prior art by integrating the battery housing, the PCB board for connecting circuits, and the bracket for installation and external wiring into an integrated design. It achieves a compact structure and high integration of the whole machine, which greatly simplifies on-site installation and maintenance. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Example: Please refer to Figures 1 to 4 This utility model provides an integrated lithium battery mounting structure, which aims to solve the problems of dispersed lithium battery pack structure, difficulty in modular expansion, and insufficient internal buffer protection in the prior art.

[0024] like Figure 1 and Figure 2 As shown, the integrated lithium battery mounting structure includes a bracket 1 and a housing 2 mounted on top of the bracket 1. The bracket 1 serves as the mounting base for the entire device, while the housing 2 houses and integrates the internal battery pack. Multiple cylinders 31, acting as storage mechanisms 3, are fixedly connected inside the housing 2 to accommodate the batteries. The integrated lithium battery mounting structure also includes a mounting mechanism 4, which securely fixes the housing 2 to the bracket 1. Specifically, the mounting mechanism 4 includes multiple fixing posts 41 fixedly connected to the inside of the housing 2. Multiple... Each limiting post 43 engages with the bottom of the fixing post 41 during assembly to achieve initial positioning and limiting of the housing 2 on the bracket 1. A PCB board 34 is threadedly connected to the top of the housing 2. The PCB board 34 has multiple holes corresponding to the positions of the fixing posts 41. Multiple screws 42 pass through the holes on the PCB board 34 in sequence and are threadedly connected to the corresponding fixing posts 41. Through the engagement of the limiting post 43 and the fixing post 41 and the threading of the screws 42, the housing 2, the PCB board 34 and the bracket 1 are firmly integrated into a whole.

[0025] Please refer to Figure 3The storage mechanism 3 includes multiple cylinders 31 fixedly connected inside the housing 2. These cylinders 31 are arranged in a rectangular array inside the housing 2, providing independent storage space for multiple batteries. In order to further cushion and protect the batteries, the storage mechanism 3 also includes multiple rubber pads 32. The multiple rubber pads 32 are slidably connected inside the cylinders 31. When the batteries are placed in the rubber pads 32, they can effectively prevent the batteries from directly contacting the inner wall of the cylinders 31, avoiding damage to the surface of the batteries from bumps. At the same time, the elastic material of the rubber pads 32 also increases the friction, preventing the batteries from shaking randomly inside. In order to enhance the structural strength and stability of the cylinders 31, the bottom of the multiple cylinders 31 are respectively fixedly connected with reinforcing ribs 33.

[0026] Please refer to Figure 4 In addition to the aforementioned fixing posts 41, limiting posts 43, PCB board 34, and screw 42 used to fix the housing 2 to the bracket 1, the installation mechanism 4 also includes a metal frame 44. The metal frame 44 is threaded to one corner of the bracket 1 by screw 45. Both outer surfaces of the metal frame 44 are square, so that the metal frame 44 can serve as an installation interface to fix a single battery module to other devices by screw connection. It can also be used to align the metal frames 44 between multiple brackets 1 when the battery capacity needs to be expanded, and then fix two adjacent metal frames 44 by thread connection, thereby quickly and stably forming a modular battery pack. This modular splicing structure ensures high stability and convenient installation of the battery pack when it is expanded.

[0027] As a preferred embodiment, please refer to Figure 2 and Figure 3 Two terminals 36 are fixedly connected to one side of the bracket 1. These two terminals 36 become the positive and negative output terminals of the entire battery module. A connecting plate 35 is electrically connected to the bottom of the PCB board 34. The connecting plate 35 is used to collect the current of the internal battery. One end of the connecting plate 35 is connected to the top of the two terminals 36, thus forming a complete electrical path to guide electrical energy from the internal battery to the external terminals 36.

[0028] As a further optimization of the above wiring structure, to ensure a secure and reliable connection of the external cable, please refer to... Figure 2 The bottoms of multiple terminals 36 pass through the center hole of the metal washer 37 in sequence and are threaded with terminals nut 38. When wiring, the terminals of the external cable can be pressed between the metal washer 37 and the terminals nut 38. By tightening the terminals nut 38, a stable and low-resistance electrical connection can be achieved.

[0029] Working principle: First, the storage mechanism 3 is installed and the battery is contained. The battery is placed into multiple cylinders 31 inside the box 2. The rubber pads 32 inside the cylinders 31 buffer and limit the battery to prevent it from shaking and bumping. Then, the PCB board 34 is placed on top of the box 2. The connector at the bottom of the PCB board 34 contacts the battery electrodes and forms an internal circuit through the connecting plate 35. Finally, the current is gathered to the terminal 36 fixed to one side of the bracket 1, so that the terminal 36 becomes the positive and negative terminals of the entire battery module. Next, the mounting mechanism 4 is assembled. The battery-equipped housing 2 is placed on top of the bracket 1, and the tops of the multiple limiting posts 43 on the top of the bracket 1 are engaged with the bottoms of the multiple fixing posts 41 inside the housing 2 to achieve initial alignment. Then, screw 42 is passed through the holes on the top of the PCB board 34 and threaded to the fixing posts 41. The housing 2 is firmly fixed to the bracket 1 by the tightening force of screw 42. Finally, the metal frame 44 is threaded to the corner of the bracket 1 by screw 45. At this time, a single integrated lithium battery module is assembled and can be fixed to other equipment by the metal frame 44, or multiple modules can be combined into a larger battery pack by aligning the metal frames 44 and connecting them with screws.
