Description

Technical Field

[0001] This utility model belongs to the technical field of lead-acid battery accessories, specifically a high-strength heat-resistant plastic shell for lead-acid batteries. Background Technology

[0002] Lead-acid batteries, as a commonly used energy storage device, are widely used in electric vehicles, backup power supplies, energy storage for communication base stations, new energy engineering machinery and other fields due to their advantages such as low cost and stable charge and discharge performance. The plastic shell, as the core protective component of lead-acid batteries, directly supports key components such as internal electrodes and electrolytes. Its strength and heat resistance play a decisive role in the battery's service life, operational stability and safety.

[0003] Currently, most lead-acid battery casings are made of ordinary plastic, which has significant shortcomings during use. On the one hand, they have low strength and are prone to cracking and deformation when subjected to external impact or compression, failing to effectively protect the internal electrodes and electrolyte. On the other hand, they have poor heat resistance, and the heat generated during battery charging and discharging can easily cause the casing to soften, which not only affects the structural stability of the battery but may also lead to safety hazards such as electrolyte leakage. Therefore, a high-strength heat-resistant lead-acid battery casing is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a high-strength heat-resistant lead-acid battery plastic shell.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The high-strength heat-resistant lead-acid battery plastic shell of this utility model includes a plastic shell body, which is made of modified PP material. A battery housing is provided inside the plastic shell body. Transverse reinforcing ribs are evenly arranged around the outer surface of the plastic shell body. Longitudinal reinforcing ribs are fixedly connected to the outer surface of the plastic shell body at the connection of the transverse reinforcing ribs. The longitudinal reinforcing ribs are evenly arranged. The transverse and longitudinal reinforcing ribs are staggered to form a grid. A heat-resistant coating is attached to the inner wall of the plastic shell body. The heat-resistant coating is a ceramic coating.

[0006] Preferably, a curved heat dissipation pipe is fixedly connected to the bottom of the battery compartment, and a placement plate is fixedly connected to the top of the curved heat dissipation pipe.

[0007] Preferably, a slot is provided at one edge of the top of the plastic shell body, an inflatable airbag is fixedly connected to the bottom of the slot, air grooves are symmetrically provided on both sides of the inflatable airbag, and a sealing airbag is fixedly connected to the top of the air groove at the edge of the top of the plastic shell body.

[0008] Preferably, a hinge is fixedly connected to the outer surface of the plastic shell body away from the slot, the hinges are symmetrically arranged, a sealing cover plate is connected to one side of the plastic shell body through the hinge, an insert block is fixedly connected to the side of the sealing cover plate near the plastic shell body at a position corresponding to the slot, and a pull block is fixedly connected to the side of the sealing cover plate away from the insert block.

[0009] Preferably, a heat dissipation hole is provided on one side of the outer surface of the plastic shell body. The heat dissipation holes are evenly distributed and each heat dissipation hole is fixedly connected to a dustproof mesh. The heat dissipation holes are symmetrically arranged.

[0010] Preferably, support feet are fixedly connected to the four corners of the bottom of the plastic shell body.

[0011] The beneficial effects of this utility model are:

[0012] By using a modified PP material for the plastic shell body, combined with interlaced horizontal and vertical reinforcing ribs in a grid pattern, the overall strength of the plastic shell is greatly improved, preventing deformation from collisions and compression. The ceramic heat-resistant coating blocks the conduction of battery heat, ensuring the heat resistance of the shell. By setting up curved heat dissipation pipes and placement plates, along with evenly distributed heat dissipation holes with dustproof mesh, heat inside the chamber is efficiently dissipated and dust is prevented. Through slots, inflatable airbags, sealing airbags, and sealing covers with inserts, the inserts compress the inflatable airbags when closed, causing the sealing airbags to expand, achieving double sealing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] Please see Figures 1-4 This utility model provides a high-strength heat-resistant lead-acid battery plastic shell, including a plastic shell body 1, which is made of modified PP material. The plastic shell body 1 has a battery compartment inside. Horizontal reinforcing ribs 2 are evenly arranged around the outer surface of the plastic shell body 1. Longitudinal reinforcing ribs 3 are fixedly connected to the outer surface of the plastic shell body 1 at the connection of the horizontal reinforcing ribs 2. The longitudinal reinforcing ribs 3 are evenly arranged. The horizontal reinforcing ribs 2 and the longitudinal reinforcing ribs 3 are staggered to form a grid. A heat-resistant coating is attached to the inner wall of the plastic shell body 1. The heat-resistant coating is a ceramic coating. Support feet 4 are fixedly connected to the four corners of the bottom of the plastic shell body 1.

[0023] During operation, the plastic shell body 1 uses modified PP material as the base material, utilizing its excellent mechanical and processing properties to construct the main frame. The internal battery housing provides a stable installation space for the lead-acid battery cells, ensuring precise positioning of the battery assembly and preventing shaking. The horizontal reinforcing ribs 2, evenly spaced around the outer surface of the plastic shell body 1, and the equidistant longitudinal reinforcing ribs 3 fixed at the connection points intersect to form a grid structure. Through the synergistic support of the ribs, the external forces on the shell are dispersed, significantly improving the overall structural strength of the plastic shell and preventing deformation of the shell due to collisions and compression during use. Or damaged; the ceramic heat-resistant coating adhering to the inner wall, with the excellent high-temperature resistance of ceramic materials, effectively blocks the heat generated during battery charging and discharging from being conducted to the shell, preventing the shell from softening and aging due to high temperature, while reducing the impact of heat accumulation on the internal components of the battery; the support feet 4 at the four corners of the bottom provide stable support for the plastic shell, keeping a certain distance between the plastic shell and the contact surface when the plastic shell is placed, which not only avoids direct force and wear on the bottom, but also facilitates air circulation to assist heat dissipation. Ultimately, through the multiple combinations of materials, structure and coating, the plastic shell achieves high-strength protection and heat resistance for lead-acid batteries.

[0024] Furthermore, such as Figure 2 and Figure 3The bottom of the battery compartment is fixedly connected to a curved heat dissipation pipe 10, and the top of the curved heat dissipation pipe 10 is fixedly connected to a placement plate 11. A heat dissipation hole 9 is opened on one side of the outer surface of the plastic shell body 1. The heat dissipation holes 9 are evenly distributed and each heat dissipation hole 9 is fixedly connected to a dustproof mesh. The heat dissipation holes 9 are symmetrically arranged.

[0025] During operation, the curved heat dissipation pipe 10 fixed at the bottom increases the contact area with the air inside the chamber. The top placement plate 11 provides stable support for the battery and conducts the heat generated by the battery during operation to the curved heat dissipation pipe 10. The heat dissipation holes 9 symmetrically and evenly distributed on one side of the outer surface of the plastic shell body 1 form a ventilation channel. The heat conducted by the curved heat dissipation pipe 10 and the hot air inside the chamber are discharged through the heat dissipation holes 9. The dustproof net inside the holes can block impurities from entering. The support feet 4 at the four corners of the bottom keep the plastic shell and the contact surface apart, assisting air circulation and heat dissipation. Finally, through the combination of multiple structures and materials, high-strength protection, high-efficiency heat resistance and stable heat dissipation of lead-acid batteries are achieved.

[0026] Furthermore, such as Figure 4 A slot 5 is provided on one edge of the top of the plastic shell body 1. An inflatable airbag 6 is fixedly connected to the bottom of the slot 5. Air grooves are symmetrically provided on both sides of the inflatable airbag 6. A sealing airbag 7 is fixedly connected to the top of the air groove at the edge of the top of the plastic shell body 1. A hinge 12 is fixedly connected to the outer surface of the plastic shell body 1 away from the slot 5. The hinges 12 are symmetrically arranged. A sealing cover plate 13 is connected to one side of the plastic shell body 1 through the hinge 12. An insert block 8 is fixedly connected to the side of the sealing cover plate 13 near the plastic shell body 1 at the position corresponding to the slot 5. A pull block 14 is fixedly connected to the side of the sealing cover plate 13 away from the insert block 8.

[0027] During operation, the slot 5 on one side edge of the top of the plastic shell body 1 cooperates with the insert 8 on the sealing cover 13. When the sealing cover 13 is closed by the hinge 12, the insert 8 is inserted into the slot 5, squeezing the inflatable airbag 6 at the bottom of the slot 5. After being squeezed, the inflatable airbag 6 introduces gas into the sealing airbag 7 through the air grooves on both sides, causing the sealing airbag 7 to expand and tightly fit the contact edge between the sealing cover 13 and the plastic shell body 1, forming a double sealing structure, effectively preventing external dust, moisture and other impurities from entering the battery compartment. The grid structure of the transverse reinforcing ribs 2 and the longitudinal reinforcing ribs 3 continuously strengthens the shell strength. The ceramic heat-resistant coating, the curved heat dissipation pipe 10 and the heat dissipation hole 9 work together to achieve heat resistance and heat dissipation. The support foot 4 ensures placement stability, while the pull block 14 facilitates the opening and closing of the sealing cover 13. Finally, through the multiple cooperation of structural reinforcement, heat dissipation and heat resistance and sealing protection, the safe operation of the lead-acid battery is guaranteed in all aspects.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
