Description

Technical Field

[0001] This utility model relates to the field of storage battery technology, specifically to a short-circuit resistant storage battery for trucks. Background Technology

[0002] Some electric vehicles, such as trucks, often use storage batteries. Storage batteries are devices that directly convert chemical energy into electrical energy. They are designed to be rechargeable and can be recharged through reversible chemical reactions.

[0003] When the positive and negative terminals of a battery are accidentally connected by a metal conductor (such as iron wire or copper sheet), a short circuit can easily occur. For example, tools may be dropped during battery installation, or metal parts around the battery may be improperly placed, or tools such as wrenches may accidentally touch the positive and negative terminals simultaneously, causing a short circuit and reducing battery safety. The battery casing is generally sealed with gaskets to achieve waterproofing, but over time, the gaskets age and thin, thus reducing the waterproofing effect during battery use. Utility Model Content

[0004] The purpose of this invention is to provide a short-circuit resistant storage battery for trucks, in order to solve the problems of low safety and poor waterproofing of storage batteries mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a short-circuit resistant storage battery for trucks, comprising a battery casing, a lower connecting plate fixed at the top edge of the battery casing, a battery cover plate covering the surface of the battery casing, an upper connecting plate fixed at the edge of the battery cover plate, mounting studs threadedly connected to the surface of the upper connecting plate, one end of the mounting stud penetrating the upper connecting plate and threadedly fastened to the surface of the lower connecting plate, electrode posts mounted on both sides of the surface of the battery cover plate, a short-circuit resistant mechanism provided on the outer side of the electrode posts, the internal components of the short-circuit resistant mechanism including an insulating protective cover, a positioning cylinder, a fastening bolt, a positioning post, and a wire hole, and a high-efficiency waterproof mechanism provided between the upper connecting plate and the lower connecting plate, the high-efficiency waterproof mechanism consisting of a sealing gasket and a compression component.

[0006] Preferably, an insulating protective cover is fitted over the outer side of the electrode post, and a wire hole is provided on one side of the insulating protective cover.

[0007] Preferably, a positioning cylinder is fixed to the surface of the insulating protective cover, and a positioning post is fixed to the surface of the battery cover plate, with the positioning post and the positioning cylinder interlocking.

[0008] Preferably, the surface of the insulating protective cover is threaded with a fastening bolt, one end of which passes through the insulating protective cover and the positioning cylinder in sequence and is fastened to the surface thread of the positioning post.

[0009] Preferably, a sealing gasket is adhered to the surface of the lower connecting plate, the sealing gasket having a U-shaped structure, and the sealing gasket being located inside the mounting stud.

[0010] Preferably, the surface of the sealing gasket is provided with a pressing component, which is mounted on the surface of the upper connecting plate. The pressing component consists of a receiving groove, a compression spring, and a pressure plate.

[0011] Preferably, the surface of the upper connecting plate is provided with a receiving groove, the receiving groove is located inside the mounting stud, and a pressure plate is slidably disposed inside the receiving groove. The pressure plate has a U-shaped structure, and the surface of the pressure plate is in close contact with the surface of the sealing gasket.

[0012] Preferably, each pressure plate has a compression spring fixed to its surface, and one end of the compression spring is fixedly connected to the inner wall of the receiving groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the short-circuit resistant truck battery can not only prevent the battery from short-circuiting when the electrode posts are accidentally connected by a metal conductor, thereby improving the safety of the battery during use, but also improve the waterproof effect of the battery during use.

[0014] By incorporating a short-circuit protection mechanism, the wire is connected to the electrode post. Then, the insulating protective cover is placed over the outside of the electrode post, and the positioning sleeve is fitted onto the surface of the positioning post to position the insulating protective cover. The wire is then placed inside the wire hole to facilitate the wire passing through the insulating protective cover. Finally, the fastening bolts are tightened to fix the insulating protective cover to the positioning post, thus securing the insulating protective cover to the outside of the electrode post. Under the action of the insulating protective cover, the electrode post can be shielded and protected, preventing short circuits in the battery when the electrode post is accidentally connected to a metal conductor, thereby improving the safety of the battery during use.

[0015] By incorporating a highly efficient waterproof mechanism, the battery cover is placed over the surface of the battery casing. The battery casing is then secured to the cover by tightening the mounting studs. At this point, the sealing gasket is in close contact with the surface of the upper connecting plate, sealing both the upper and lower connecting plates. Simultaneously, a compression spring pushes a pressure plate downwards along the inside of the receiving groove, ensuring the pressure plate always presses firmly against the sealing gasket. Even after the sealing gasket wears down and thins, the pressure plate remains in close contact with it, sealing both the upper and lower connecting plates. This achieves a highly efficient sealing function for the battery, thereby improving its waterproof performance during use. Attached Figure Description

[0022] The present invention provides a short-circuit resistant storage battery for trucks with the following structure: Figure 1 and Figure 2 As shown, the battery includes a battery casing 1, a lower connecting plate 14 fixed at the top edge of the battery casing 1, a battery cover plate 11 covering the surface of the battery casing 1, an upper connecting plate 12 fixed at the edge of the battery cover plate 11, and mounting studs 13 threadedly connected to the surface of the upper connecting plate 12. One end of the mounting stud 13 passes through the upper connecting plate 12 and is threadedly fastened to the surface of the lower connecting plate 14. Electrode posts 15 are installed on both sides of the surface of the battery cover plate 11.

[0023] Furthermore, such as Figure 4As shown, an anti-short-circuit mechanism 2 is provided on the outside of the electrode post 15. The anti-short-circuit mechanism 2 includes an insulating protective cover 21, a positioning cylinder 22, a fastening bolt 23, a positioning post 24, and a wire hole 25. An insulating protective cover 21 is sleeved on the outside of the electrode post 15. A wire hole 25 is opened on one side of the insulating protective cover 21. The positioning cylinder 22 is fixed on the surface of the insulating protective cover 21. Positioning posts 24 are fixed on the surface of the battery cover 11. The positioning posts 24 and the positioning cylinder 22 are interlocked. The surface of the insulating protective cover 21 is threaded with a fastening bolt 23. One end of the fastening bolt 23 passes through the insulating protective cover 21 and the positioning cylinder 22 in sequence and is fastened to the surface of the positioning post 24 by the thread.

[0024] In use, connect the wire to the electrode post 15, then cover the outside of the electrode post 15 with the insulating protective cover 21, and fit the positioning cylinder 22 onto the surface of the positioning post 24 to position the insulating protective cover 21. Place the wire inside the wire hole 25 to facilitate the wire passing through the insulating protective cover 21. Then tighten the fastening bolt 23 to fix the insulating protective cover 21 to the positioning post 24, thereby fixing the insulating protective cover 21 to the outside of the electrode post 15. Under the action of the insulating protective cover 21, the electrode post 15 can be shielded and protected to prevent the battery from short-circuiting if the electrode post 15 is accidentally connected to a metal conductor.

[0025] Furthermore, such as Figure 3 As shown, a high-efficiency waterproof mechanism 3 is provided between the upper connecting plate 12 and the lower connecting plate 14. The high-efficiency waterproof mechanism 3 consists of a sealing gasket 31 and a pressing component 32. The sealing gasket 31 is adhered to the surface of the lower connecting plate 14. The sealing gasket 31 has a U-shaped structure and is located inside the mounting stud 13. The pressing component 32 is provided on the surface of the sealing gasket 31 and is installed on the surface of the upper connecting plate 12. The pressing component 32 consists of a receiving groove 321, a compression spring 322, and a pressure plate 323. The receiving groove 321 is opened on the surface of the upper connecting plate 12 and is located inside the mounting stud 13. The pressure plate 323 is slidably arranged inside the receiving groove 321. The pressure plate 323 has a U-shaped structure and its surface is tightly attached to the surface of the sealing gasket 31. The surface of the pressure plate 323 is fixed with a compression spring 322, and one end of the compression spring 322 is fixedly connected to the inner wall of the receiving groove 321.

[0026] In use, the battery cover 11 is placed on the surface of the battery casing 1, and then the battery casing 1 and the battery cover 11 are fixed by tightening the mounting studs 13. At this time, the sealing gasket 31 is in close contact with the surface of the upper connecting plate 12, sealing the upper connecting plate 12 and the lower connecting plate 14. At the same time, the compression spring 322 pushes the pressure plate 323 to slide downward along the inside of the receiving groove 321, so that the pressure plate 323 always presses the sealing gasket 31 tightly. Even if the sealing gasket 31 is worn, aged and thinned, the pressure plate 323 will still be in close contact with the sealing gasket 31, sealing the upper connecting plate 12 and the lower connecting plate 14, so as to achieve the efficient sealing function of the battery.

[0027] Working principle: In use, first cover the battery cover 11 onto the surface of the battery casing 1, and then fix the battery casing 1 and the battery cover 11 by tightening the mounting studs 13. At this time, the sealing gasket 31 is in close contact with the surface of the upper connecting plate 12, sealing the upper connecting plate 12 and the lower connecting plate 14. At the same time, the compression spring 322 pushes the pressure plate 323 to slide downward along the inside of the receiving groove 321, so that the pressure plate 323 always presses the sealing gasket 31 tightly. Even if the sealing gasket 31 is worn, aged and thinned, the pressure plate 323 will still be in close contact with the sealing gasket 31, sealing the upper connecting plate 12 and the lower connecting plate 14, so as to achieve the efficient sealing function of the battery, thereby improving the waterproof effect of the battery during use.

[0028] In use, the wire can be connected to the electrode post 15, and then the insulating protective cover 21 is placed on the outside of the electrode post 15. The positioning cylinder 22 is then fitted onto the surface of the positioning post 24 to position the insulating protective cover 21. The wire is then placed inside the wire hole 25 to facilitate the wire passing through the insulating protective cover 21. The fastening bolt 23 is then tightened to fix the insulating protective cover 21 to the positioning post 24, thereby fixing the insulating protective cover 21 to the outside of the electrode post 15. Under the action of the insulating protective cover 21, the electrode post 15 can be shielded and protected, preventing the battery from short-circuiting if the electrode post 15 is accidentally connected to a metal conductor, thus improving the safety of the battery during use and finally completing the battery use.
