Description

Technical Field

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

[0002] High-rate lead-acid batteries, also known as rate-capacity batteries, are batteries with high energy output capabilities, typically capable of releasing a large amount of electrical energy in a short time to support high-load operation. High-rate batteries usually employ a multi-plate structure, which increases the reaction area of ​​the plates, thereby improving the utilization rate of active materials and the current density per unit area, thus enhancing high-current discharge performance. Furthermore, high-rate batteries use a relatively higher electrolyte density, and the amount of lead paste applied to the plates should also be appropriately increased. Based on these structural and performance changes, high-rate lead-acid batteries significantly exceed conventional lead-acid batteries in terms of current intensity and heat generation. To ensure safe use, these products generally integrate safety monitoring modules for real-time monitoring of temperature, smoke, and other information to promptly detect overheating or even spontaneous combustion. However, conventional monitoring components are integrated structures, making replacement and maintenance inconvenient, and their structure is not compact enough to achieve modular installation and use. Summary of the Invention

[0003] The technical problem to be solved by this utility model is: how to design a battery temperature monitoring component that can be modularly installed and used.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0005] A modular structure for a high-rate lead-acid battery includes a filling port, a battery body, a slot, terminals, a support shell, a protrusion, a screw, a recessed groove, a terminal lug, a motor, a guide post, a temperature probe, a lead screw, a lifting plate, and contacts. The battery body has a slot located outside the filling port. The battery body's terminals are located beside the slot. The support shell has a protrusion on its side, which engages with the slot. A recessed groove is provided on the protrusion, and a screw is placed within the recessed groove, passing through the protrusion and securely connected to the battery body's outer casing. A terminal lug is provided on the support shell. A motor is mounted on the support shell and is connected to the lead screw. The lifting plate is threadedly connected to the lead screw. A guide post is fixedly connected to the support shell, passing through the lifting plate and slidingly engaging with it. A temperature probe is mounted on the support shell. Contacts are connected to the lifting plate and electrically connected to the terminal lug.

[0006] Preferably, the device also includes a housing, which is fixedly connected to the support shell and covers the outside of the motor.

[0007] Preferably, the electrical connection between the contact and the terminal block is achieved by the following structure: a connecting spring is connected to the terminal block, and the contact is connected to the connecting spring.

[0008] Preferably, a base plate and a pressure head are connected sequentially to the end of the connecting spring, and the pressure head is connected to the contact point.

[0009] Preferably, the device also includes an alarm that is electrically connected to the temperature probe.

[0010] Preferably, the wiring ear is located outside the support housing, while the guide post, temperature probe, lead screw, lifting plate, and contacts are enclosed inside the support housing.

[0011] In the above technical solution, a slot is provided on the outer casing of the battery body, and a recessed step is also provided to accommodate the supporting shell. Apart from the slot and recessed step, the other structures of the battery body are conventional. The filling port and terminals are existing components of the battery body. The slot and recessed step must avoid the filling port, while the terminals are located within the recessed step. A protrusion is used to mate with the slot to position the supporting shell, which is then secured with screws. The recessed groove accommodates the screws. A terminal lug is used to connect electrical appliances via wires. The motor drives the lead screw to rotate. Since the lifting plate is threaded to the lead screw, it can be driven to move up and down. The guide post guides the movement during this process. When the lifting plate descends, the contacts contact the terminals, making the terminal lug conductive. When the lifting plate rises, the contacts leave the terminals, thus forcibly cutting off power. When the temperature probe detects overheating, this forced power-off mechanism ensures safety.

[0012] This invention provides a modular structure for a high-rate lead-acid battery. The technical solution incorporates a modularly installable and usable temperature monitoring component. Furthermore, the clutch function between the connector lugs and terminals allows for forced power disconnection, ensuring safety. Attached Figure Description
