Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid batteries, in particular to a waterproof charging device for lead-acid batteries. Background Art

[0002] In the existing lead-acid battery technology, simple waterproofing is mostly adopted. However, in this way, when used in a humid environment, it is easy to get water in. For example, the Chinese patent discloses "a waterproof charging device for lead-acid batteries" with the application number "CN202020547299.3". It uses a pull ring to drive the corresponding sliding rod to move, the insertion block squeezes the compression spring and slides out of the slot, moves the protection box, places the lead-acid battery to be charged on the bottom plate, then inserts the charging plug into the charging port of the lead-acid battery, and then puts down the protection box. The insertion block slides into the corresponding slot to fix the position of the protection box, so as to achieve the waterproof effect. However, when used in a humid environment, water will enter the interior along the charging port, and the charging device may be damaged due to water ingress, resulting in abnormal operation or even safety problems. Summary of the Utility Model

[0003] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a waterproof charging device for lead-acid batteries. Through the cooperation of the first wire outlet, the second wire outlet and the baffle, when charging the lead-acid battery, since the height of the first wire outlet is smaller than that of the second wire outlet, water directly enters the drainage groove, ensuring that water does not enter the lead-acid battery to damage the battery. Through the cooperation of the rubber soft pad, the side plate, the spring and the slide rail, when closing the upper cover, due to the extrusion between the two rubber soft pads, the upper rubber soft pad moves upward along the slide rail to prevent damage to the rubber soft pad. When reaching the maximum limit of the slide rail, the rubber soft pad can only be extruded along the gap between the two side plates to achieve a sealing effect, thereby preventing water from entering the interior of the charging device. Even if a small amount of water stains enter, due to the height of the baffle, the water cannot enter the lead-acid battery. The multi-layer waterproof structure design can effectively prevent water from entering the device interior and ensure the safety and reliability when used in a humid environment or outdoors.

[0004] The present utility model also provides a waterproof lead-acid battery charging device having the above-described structure, including: a box body, inside which a battery body is provided, and a socket is arranged on the battery body; a baffle is fixedly connected to the inner bottom surface of the box body, and the height of the baffle is greater than that of the box body; a first base is fixedly connected to the inner side surface of the box body; a second wire passing opening is arranged on the baffle; a first wire passing opening is arranged on the box body, and the height of the first wire passing opening is smaller than that of the second wire passing opening; an upper cover, on the inner side surface of which a second base is fixedly connected, and a slide rail is arranged on the upper cover, inside which a support frame is slidably connected; a spring and a limiting rod are arranged between the support frame and the second base; rubber soft pads and side plates are arranged on the lower surface of the support frame and the upper surface of the first base. Through the above device, through the cooperation of the baffle, rubber soft pads, side plates, spring, first wire passing opening and second wire passing opening, moisture is effectively prevented from entering the interior of the device, ensuring safety and reliability when used in a humid environment or outdoors.

[0006] According to a waterproof lead-acid battery charging device of the present utility model, four clamping plates are fixedly connected to the inner bottom surface of the box body, and all four clamping plates are in contact with the battery body. Through the above device, the battery body is prevented from shaking inside through the clamping plates.

[0007] According to a waterproof lead-acid battery charging device of the present utility model, the battery body is located inside the baffle, and a drainage groove is arranged between the baffle and the interior of the box body. Through the above device, the remaining water inside is effectively discharged through the drainage groove.

[0008] According to a waterproof lead-acid battery charging device of the present utility model, a drainage opening is arranged on the drainage groove, and the inner bottom surface of the drainage groove is in a slope shape. Through the above device, the water stains are effectively discharged through the drainage opening.

[0009] According to a waterproof lead-acid battery charging device of the present utility model, both the second base and the support frame surround the inner wall of the upper cover, and the second base is located directly above the support frame. Through the above device, the sealing performance is effectively improved through the positions of the second base and the support frame.

[0010] According to a waterproof lead-acid battery charging device of the present utility model, the rubber soft pads are located between the side plates and the box body and the upper cover, and a gap is arranged between the two side plates. Through the above device, the rubber soft pads can be conveniently extruded out through the gap.

[0011] A waterproof lead-acid battery charging device according to the present utility model, four legs are fixedly connected to the lower surface of the box body, and a lock is provided on the upper cover. Through the above device, the box body is effectively supported by the legs to drain water stains. Through the lock, the upper cover and the box body are effectively locked together.

[0012] Beneficial effects

[0013] Compared with the prior art, for the waterproof lead-acid battery charging device, through the cooperation of the first wire outlet, the second wire outlet, and the baffle, when charging the lead-acid battery, since the height of the first wire outlet is smaller than that of the second wire outlet, water directly enters the drainage groove, ensuring that water does not enter the lead-acid battery and damage the battery. Through the cooperation of the rubber soft pad, the side plate, the spring, and the slide rail, when closing the upper cover, due to the extrusion between the two rubber soft pads, the upper rubber soft pad moves upward along the slide rail to prevent damage to the rubber soft pad. When reaching the maximum limit of the slide rail, the rubber soft pad can only be extruded along the gap between the two side plates to achieve a sealing effect, thereby preventing water from entering the inside of the charging device. Even if a small amount of water stains enter, due to the height of the baffle, the water cannot enter the lead-acid battery. The multiple waterproof structure design can effectively prevent water from entering the inside of the device, ensuring safety and reliability when used in a humid environment or outdoors.
