Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a multi-plate assembly structure for a high-rate lead-acid battery. Background Technology

[0002] Lead-acid batteries are currently the most widely used high-efficiency type of battery in high-power power supplies. High-rate lead-acid batteries are a special type of lead-acid battery, manufactured using high-purity lead alloy plates and pure lead ingots, featuring high energy density, high discharge rate, and long lifespan. Compared to traditional lead-acid batteries, high-rate lead-acid batteries can provide a large amount of electrical energy in a short time, making them suitable for applications requiring instantaneous high energy output.

[0003] High-rate lead-acid batteries have higher energy density and charging efficiency, enabling them to provide a large amount of electrical energy in a short time, making them suitable for applications requiring instantaneous high energy output. Utilizing special container design and formulation technology, they improve battery life and cycle life, reducing maintenance costs. Even when not in use for extended periods, they maintain a high level of charge storage. High-rate lead-acid batteries are suitable for use in electric vehicles, hybrid vehicles, and pure electric vehicles as starting and power batteries; they can serve as backup power, providing reliable power during power outages or grid failures; they can be used for grid peak shaving, balancing power supply and demand, mitigating peak-valley differences, and improving grid stability; and they can also be used for energy storage in solar power systems, storing excess electrical energy for later use when needed.

[0004] High-rate lead-acid batteries improve high-current, short-time discharge efficiency by enhancing electrolyte transport, the heat resistance of battery conductors, and reducing voltage drop. Specific measures include reducing plate thickness, increasing electrolyte concentration, increasing lead paste acid content, and reducing lead paste apparent density. These techniques place higher demands on the plate assembly structure. Currently, the stability of conventional assembly structures needs improvement, especially when facing external impacts and vibrations, which can easily lead to loosening or even detachment. Since the tightness and uniformity of the plates directly affect discharge performance, this deficiency in resistance to external forces not only affects the battery's lifespan but also directly impacts its performance within that lifespan. Summary of the Invention

[0005] This utility model aims to address the technical deficiencies of existing technologies by providing a multi-plate assembly structure for high-rate lead-acid batteries, thereby solving the technical problem that the resistance of conventional assembly structures to external impact needs to be improved.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0007] A high-rate lead-acid battery multi-plate assembly structure includes a tank, plates, positioning frames, keyways, sliding sleeves, toothed portions, locking heads, horizontal ribs, vertical ribs, a first vertical plate, a second vertical plate, flexible material, limiting plates, protrusions, and busbars. The plates are stacked on top of each other and located within the tank. Two positioning frames are located on either side of the plates. Keyways and sliding sleeves are connected to the two positioning frames respectively. The keyways have toothed portions, and the sliding sleeves have locking heads to prevent key retraction. The locking heads engage with the toothed portions. The outer surface of the device is provided with horizontal ribs and vertical ribs, which intersect each other. At least two second vertical plates extending vertically are provided on the outer side of the positioning frame.

Flexible material is filled between the groove and the positioning frame. A limiting plate covering part of the upper part of the electrode plate is provided on the top of the positioning frame. A protrusion is provided on the top of the positioning frame. A busbar is connected to the protrusion and is electrically connected to the electrode plate.

[0008] Preferably, the chuck has a ratchet structure, with the root of the chuck rotatably connected to the slide sleeve via a spring hinge, and the end of the chuck inserted into the toothed part.

[0009] As a preferred option, the flexible material is flame-retardant rubber.

[0010] Preferably, the key and the sliding sleeve are connected to the limiting plates of the positioning frames on both sides.

[0011] Preferably, the positioning frame is provided with several through holes.

[0015] In this utility model, the electrode plate essentially includes a positive electrode plate, a separator, and a negative electrode plate stacked together. Since it adopts a conventional structure, it will not be described in detail.

[0016] In the above technical solution, the tank serves as the inner wall of the battery cavity, accommodating the electrode plates. The electrode plates are stacked to form an electrode group for outputting electrical energy. The positioning frame clamps and positions the stacked electrode plates from both sides, ensuring they are not easily deformed. In this clamping and positioning structure, the key and sliding sleeve are inserted into each other, and the locking head on the sliding sleeve engages with the toothed portion on the key, thus locking the clamping and positioning structure. The toothed portion can be ratchet, and the locking head can be a pawl structure; when release is needed, the locking head can be rotated to disengage from the toothed portion. Horizontal and vertical ribs provide structural reinforcement. The first and second vertical plates can serve as force points or positioning points, facilitating the installation of the positioning frame within the tank. Flexible material is used to fill the space between the tank and the positioning frame. The limiting plate serves to restrict the upper end of the electrode plates and also as an installation point for the key and sliding sleeve. A tab is used to install the busbar, which can be a conventional structure for wiring.

[0017] This invention provides a multi-plate assembly structure for a high-rate lead-acid battery. The technical solution incorporates a clamping and positioning component for the stacked plates. This component, with a positioning frame as its main body, uses a toothed key that engages with a locking head on a sliding sleeve, effectively improving the stability of the stacked plate structure. This invention enhances the battery's resistance to external impacts and its own vibrations, thus extending its service life. Attached Figure Description
