Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, specifically to a battery pack installation fixture. Background Technology

[0002] A battery is a device that directly converts stored chemical energy into electrical energy through a chemical reaction. It consists of a positive electrode (anode), a negative electrode (cathode), an electrolyte (ion conductor), and a separator (to prevent short circuits). During the reaction, the electrode materials undergo oxidation-reduction reactions, electrons move directionally through the external circuit to form an electric current, and ions migrate through the electrolyte to maintain charge balance. Primary batteries are non-rechargeable (such as alkaline batteries and zinc-manganese batteries), where the chemical reaction is irreversible. Secondary batteries are rechargeable (such as lithium-ion batteries and lead-acid batteries), where the chemical reaction can be reversed by charging. They provide direct current, and their voltage and capacity depend on the materials and design. They are portable, stable, and widely used in electronic devices, transportation, and other fields.

[0003] A battery pack is a system composed of multiple individual batteries connected in series or parallel. It is designed to meet higher voltage, capacity, or energy requirements. Series connection increases the total voltage (e.g., a 3.7V lithium battery connected in series becomes 12V or higher), parallel connection increases the total capacity (e.g., multiple batteries connected in parallel extend the life of the device), and hybrid connection combines series and parallel connections to balance voltage and capacity (e.g., electric vehicle battery packs). Through collaborative work, it achieves performance that a single battery cannot achieve (e.g., high-voltage drive motors, long-term power supply). It is usually equipped with a battery management system (BMS) to monitor voltage, temperature, and equalize charge and discharge to ensure safety and lifespan. In scenarios requiring high energy output, such as electric vehicles, energy storage power stations, and large UPS power supplies, individual batteries work independently with limited voltage / capacity and are suitable for low-power devices (e.g., remote controls, flashlights). Battery packs, on the other hand, are multiple batteries working together to meet complex requirements through system design (e.g., high-voltage drive for electric vehicles, backup power for base stations). Therefore, a battery is a "single energy unit," while a battery pack is a "combined system of multiple units."

[0004] In existing technologies, the actual series installation of battery packs in distribution cabinets is very inconvenient. Wires are prone to touching the connectors and cabinet body, causing short circuits. Furthermore, the battery packs are easily grounded due to their proximity to the cabinet. Replacing battery packs requires removing and installing them one by one, and careful identification of the positive and negative terminals is crucial; misidentification or confusion can lead to short circuits. Tightening screws in the confined space of the distribution cabinet is also very inconvenient; loose tightening can result in poor connections, overheating, or short circuits. If a battery pack connector with one open circuit moves, it can easily touch other connectors and cause a short circuit. Based on these problems, we propose a battery pack installation fixture.

[0024] 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.

[0025] Reference Figure 1-4A battery pack installation fixture includes a battery pack connector 4 with multiple equally spaced battery slots running through it. Each battery slot is filled with a modular battery 7. Electrical connection devices are installed at the openings of the battery slots. These electrical connection devices are standardized and compatible with various models of modular batteries 7, greatly improving the versatility and adaptability of the installation fixture. Each electrical connection device includes two horizontal slots running through the openings of the battery slots, each with a vertical slot running through it. Connecting posts 5 are fixedly connected to each of the two vertical slots. The connecting posts 5 are made of high-strength copper alloy, possessing good conductivity and mechanical strength, ensuring they are not easily deformed during long-term use. Battery connection terminals 6 are rotatably connected to the side walls of each of the two connecting posts 5. The battery connection terminals 6 employ an elastic contact structure, automatically adjusting the contact pressure to ensure a stable and reliable connection with the electrodes of the modular batteries 7. The two battery connection terminals 6 are positioned corresponding to the electrodes of the modular batteries 7 at their respective locations.

[0026] The battery pack connector 4 is topped with an end cap 1, made of lightweight aluminum alloy, which effectively reduces overall weight while maintaining strength, facilitating handling and operation. A heat dissipation device is installed throughout the upper part of the end cap 1, employing a unique convection design to ensure the battery pack operates within its optimal temperature range. The heat dissipation device includes two heat dissipation slots extending through the upper part of the end cap 1. Each slot opening is equipped with a filter screen 10 made of stainless steel, with precisely calculated mesh sizes to effectively block dust entry without significantly affecting heat dissipation efficiency. Dust baffles 2 are installed at the openings of both heat dissipation slots. These baffles are removable for regular cleaning and maintenance, extending the lifespan of the heat dissipation device. Through-slots are installed along the side walls of both dust baffles 2, each containing an additional filter screen 10. This dual filtration design further enhances dust prevention, making it particularly suitable for use in dusty industrial environments. Both dust baffles 2 are fixedly connected to the upper part of the end cap 1 via multiple fixing posts 11.

[0027] Specifically, a positioning device is fixedly connected to the side wall of the end cover 1. The positioning device uses a combination of mechanical positioning and magnetic assistance to ensure precise alignment between the battery pack connector 4 and the end cover 1, avoiding misalignment during installation. The positioning device includes a positioning plate 9 fixedly connected to the side wall of the end cover 1, and the position of the positioning plate 9 corresponds to the position of the side wall of the battery pack connector 4.

[0028] Specifically, two electrode modules 3 are fixedly connected to the side wall of the end cap 1 and the side wall of the battery pack connector 4. The electrode modules 3 adopt a waterproof and sealed structure to prevent moisture and humid air from entering the internal circuit, thereby improving safety.

The design of the transport device fully considers ergonomic principles, enabling the tooling to be easily moved and positioned in different scenarios. The transport device includes two transport slots 12 that are installed through the lower end of the battery pack connector 4, and the two transport slots 12 extend laterally through the lower end of the battery pack connector 4.

[0029] It is worth mentioning that two connecting bolts 8 are threaded through the side wall of the battery pack connector 4. These bolts 8 feature an anti-loosening design, maintaining a stable connection even in vibration environments, making them particularly suitable for mobile device applications. Corresponding threaded grooves are provided at the lower end of the end cap 1 at the corresponding location. The two battery connector ends 6 located in the same battery slot are symmetrically positioned. This symmetrical design simplifies the installation process, allowing operators to quickly complete the connection without needing to distinguish directions. Both battery connector ends 6 can rotate 360 ​​degrees, enabling them to adapt to different installation angles and greatly improving assembly flexibility.

[0030] Specifically, anti-slip pads are installed at the bottom of both transport troughs 12. These pads are made of high-friction silicone material, effectively preventing the tooling from sliding during transport and ensuring operational safety. A magnetic sheet is installed on the side wall of the positioning plate 9 where it connects to the battery pack connecting seat 4. This magnetic sheet is made of rare-earth permanent magnet material, providing sufficient attraction to ensure positioning while facilitating manual separation.
