Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, in particular to a lithium iron phosphate battery pack clamp for a truck starting power supply. Background Art

[0002] Automotive starting batteries are primarily used for starting, lighting, and ignition. Depending on the target market, the market can be divided into the accessory market and the maintenance market. The accessory market targets new cars, with each vehicle being shipped with a battery. The maintenance market involves battery replacement during use. Since batteries are used every time a car starts, and their cycle life is limited, they require regular replacement. Frequently used vehicles require replacement more frequently. For example, trucks typically require a replacement once a year, while family cars typically require a replacement every three years. In general, automotive starting batteries are considered "fast-consumable items" and require replacement every two years on average. As cars become increasingly intelligent, everything from central control entertainment systems, audio systems, and lights to engine spark plugs, fuel injectors, and even the throttle valve requires batteries to function properly. While conventional lead-acid batteries are inexpensive, they suffer from short lifespans and low charge and discharge efficiency, directly impacting vehicle performance. With the advancement of technology, the trend toward lithium iron phosphate (LiFePO4) batteries as starting batteries for automobiles is also shifting. These batteries offer the following key advantages: a longer service life, a more stable voltage platform, lower fuel consumption, lighter weight, easier storage, and rechargeability. Furthermore, lead-acid batteries contain a significant amount of heavy metals, and improper handling can have a significant impact on the environment. LiFePO4 batteries, on the other hand, are generally considered to be green and environmentally friendly, containing no heavy or rare metals, non-toxic or pollution-free, and complying with European regulations. Therefore, they are currently the most commonly used starting batteries for automobiles.

[0003] In the actual production process, the existing lithium iron phosphate batteries are all bare cells with aluminum shell structures, which need to be assembled into battery packs before they can be used. Since the aluminum shell is very soft and thin, a clamp is needed during the assembly process. The clamp is a device used to fix the processing object during the assembly process. If the outer wall is damaged during the clamping process, its quality will be affected. After searching, the patent document with the authorization announcement number CN216000531U discloses a square aluminum shell battery mechanical clamp, and the patent document with the authorization announcement number CN218707035U discloses a lithium battery clamp. From the contents disclosed in the two retrieved patent documents, it can be seen that a clamp with usage requirements is provided from different angles. In order to reduce assembly costs, improve assembly efficiency, and more importantly, ensure the stability of assembly quality, the existing clamp is optimized to provide a clamp different from that disclosed in the prior art to meet the usage requirements.

In order to reduce the weight of the clamp assembly 2, while reasonably reducing the weight of the clamp, the structural strength and rigidity of the clamp are ensured. The present embodiment adopts a lithium iron phosphate battery pack clamp for a truck starting power supply described in the present invention. The clamp 21 includes a guide plate 211 and a clamping plate 212. The clamping plate 212 is fixed to the bottom of the guide plate 211, wherein the guide plate 211 and the clamping plate 212 are both arranged in a square structure, and the width of the clamping plate 212 is greater than the width of the guide plate 211.

[0034] The lithium iron phosphate battery pack clamp for truck starting power supply described in the utility model has the following working principle: since the external screw threads of the two screw rods 13 connected to the two output shafts of the double-headed motor 12 have opposite spiral directions, the internal threads in the clamping jaws 21 connected to the screw rod 13 match them, and the clamping jaws 21 are threadedly connected to the screw rod 13.

The magnet 33 can be reused, which greatly simplifies the maintenance and replacement process, reduces the maintenance cost of the fixture, shortens the maintenance time, and reduces the adverse effects of maintenance on production. This can greatly improve work efficiency and reduce processing costs. In addition, since the clamping jaw 21 and the mounting plate 22 are detachably connected by screws 23, the corresponding mounting plate 22 can be selected to meet the clamping requirements according to the assembly requirements of lithium iron phosphate batteries of different specifications.

[0035] The double-headed motor 12 described in the drive assembly 1 of the present invention adopts a synchronous variable-frequency speed-regulating motor, the purpose of which is to facilitate speed adjustment. Since the double-headed motor 12 is a common power device in the prior art and can be purchased on the existing market according to demand, it does not involve any structural changes to its structure and only needs to meet the use requirements. Therefore, it is not described in detail in the specification. In addition, the screw 13 and the screw bearing seat 14 are both common rotating devices in the prior art. Since it does not involve any structural changes to its structure and only needs to meet the use requirements, it is not described in detail in the specification.

[0036] To sum up, the clamp described in the present invention can not only meet the assembly requirements of lithium iron phosphate batteries of different specifications, but also prevent wear or damage to the battery surface during the clamping process, and facilitate timely replacement of damaged rubber pads. At the same time, it can also reduce processing costs. Its overall structure is simple, easy to disassemble and assemble, and it is highly practical and worthy of promotion and use.

[0037] Other aspects of the present invention that are not described in detail are all conventional technologies known to those skilled in the art.
