Description

Technical Field

[0001] The present invention relates to the technical field of forklift batteries, and particularly to a forklift battery structure with a waterproof structure. Background Art

[0002] A forklift battery is a power supply device specifically designed for forklifts. It usually stores energy through charging and then supplies it to the forklift for operation. Forklift batteries have relatively high voltage and capacity, and can continuously provide power for the forklift, enabling it to efficiently transport goods. Using a forklift battery can facilitate and quickly operate the forklift and improve work efficiency.

[0003] When the existing forklift batteries are in use, they are usually placed in a battery box, and the battery box provides protection for the forklift batteries to prevent them from being damaged by moisture. Before using the forklift batteries, the electrical equipment on the forklift needs to be connected to the negative terminal and positive terminal on the forklift batteries through a wire harness. However, the sealing performance between the wire harness connected to the external forklift battery and the battery box is average, and water vapor is likely to enter the forklift batteries through the gap at the connection between the two. The waterproof effect of the forklift batteries is general. Therefore, we propose a forklift battery structure with a waterproof structure. Summary of the Invention

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1:

[0020] Please refer to Figures 1-3, the present invention provides a technical solution: a forklift battery structure with a waterproof structure. The forklift battery is a power supply device specifically designed for forklifts. When the existing forklift batteries are in use, they are usually placed in a battery box, and the battery box provides protection for the forklift battery to prevent the forklift battery from being damaged by moisture. Before using the forklift battery, the electrical equipment on the forklift needs to be connected to the negative terminal and positive terminal on the forklift battery through a wire harness. However, the sealing performance between the wire harness connected to the external forklift battery and the battery box is average, and water vapor is likely to enter the forklift battery through the gap at the connection between the two. The waterproof effect of the forklift battery is general. It includes a battery box 1 and a forklift battery main body 7. A cover plate 3 is installed on the top of the battery box 1. In the middle of the upper surface of the cover plate 3, a waterproof seal box 5 is installed. Inside the waterproof seal box 5, there are two groups of external wire harnesses 6 electrically connected to the forklift battery main body 7. And in the middle of the inner cavity of the waterproof seal box 5, there is a partition plate 10. Sealing layers 11 are provided on both side surfaces of the partition plate 10. The left and right side walls of the waterproof seal box 5 are both slidably connected with pull rods 14. And at the bottom of the pull rod 14, a sliding plate 8 is installed. On the side of the two sliding plates 8 close to the external wire harness 6, there are clamping plates 9. And on the inner side surface of the clamping plate 9, there is an inner sealing pad 12.

[0021] The waterproof seal box 5 is fixedly connected to the top cover 3, and the partition plate 10 is fixedly connected to the middle of the inner cavity of the waterproof seal box 5. When installing the external wire harness 6, the top cover 3 is opened, and the bottoms of the two groups of external wire harnesses 6 are respectively connected to the positive terminal and negative terminal on the forklift battery main body 7. The tops of the two groups of external wire harnesses 6 penetrate through the top of the waterproof seal box 5. During this process, both groups of pull rods 14 are pulled outwards, so that the clamping plates 9 and the inner sealing pads 12 are away from the external wire harness 6. At this time, the sliding plates 8 move outwards, and the return springs 13 are in a compressed state, leaving enough space for the external wire harness 6 to pass through. Then the top cover 3 is installed on the battery box 1, and the pull rods 14 are released. The compressed return springs 13 can automatically return to their original positions, that is, drive the two groups of sliding plates 8 and the inner sealing pads 12 to move in opposite directions, so that the inner sealing pads 12 closely fit on the outer wall of the external wire harness 6. With the setting of the sealing layers 11 on both side surfaces of the partition plate 10, it can play an all-round sealing role for the external wire harness 6 electrically connected to the forklift battery, effectively preventing water vapor from entering the interior of the forklift battery through the gap at the connection between the external wire harness 6 and the cover plate 3, improving the waterproof performance of the forklift battery, making the forklift battery not easily damaged by moisture, and extending the service life of the forklift battery.

[0022] Among them, preferably, the sliding plate 8 is slidably connected to the inner wall of the waterproof seal box 5, and return springs 13 are installed between both ends of the outer side surface of the sliding plate 8 and the inner wall of the waterproof seal box 5; both ends of the return spring 13 are fixedly connected to the inner wall of the waterproof seal box 5 and the outer side wall of the sliding plate 8.

[0023] Preferably, openings adapted to the external wiring harness 6 are provided on both the cover plate 3 and the waterproof seal box 5, and a positive electrode post and a negative electrode post adapted to the two groups of external wiring harnesses 6 are provided on the forklift battery main body 7.

[0024] Preferably, the cover plate 3 is connected to the battery box 1 by screws, and a gasket is provided at the connection between the cover plate 3 and the battery box 1; the cover plate 3 installed by screws is convenient to open and close, and the gasket improves the sealing performance of the connection between the cover plate 3 and the battery box 1, preventing water vapor from entering the interior through the gap between the two.

[0025] Preferably, pull rings 15 are installed at the outer ends of the two groups of tie rods 14, and anti-slip rubber sleeves are sleeved on the hand-held ends of the pull rings 15; the pull rings 15 facilitate the pulling of the tie rods 14, and the anti-slip rubber sleeves play an anti-slip role, preventing the hand from slipping when holding the pull rings 15.

[0026] Embodiment 2:

[0027] Refer to Figure 1 , the difference between this embodiment and the first embodiment is that a base 2 is installed at the bottom of the battery box 1, and a moisture-proof pad is provided on the lower surface of the base 2. Both ends of the upper surface of the cover plate 3 are connected with handles 4. The base 2 supports the battery box 1, the moisture-proof pad plays a moisture-proof role, and the handles 4 facilitate the removal and installation of the cover plate 3.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
