Description

Technical Field

[0001] This utility model belongs to the field of battery charger technology, and in particular relates to a battery charger with multiple heat dissipation structures. Background Technology

[0002] A battery charger is an electronic device that converts alternating current (AC) or direct current (DC) into a voltage and current suitable for charging batteries. It is primarily used to replenish the energy of rechargeable batteries (such as lithium-ion, nickel-metal hydride, and lead-acid batteries). Its core functions include voltage / current regulation, charging status monitoring, and charging protection (such as overcharge, over-discharge, and short-circuit protection). Widely used in mobile phones, electric vehicles, and energy storage systems, it features high efficiency, safety, and portability.

[0003] Existing battery chargers have the following shortcomings in use: most battery chargers rely on ventilation holes for heat dissipation, which is not very effective. In addition, these ventilation holes are open to the outside, allowing water to easily enter the battery charger. As a result, the battery chargers are not waterproof and are easily damaged by high temperatures or water ingress. Therefore, based on actual usage, we have made improvements to the above-mentioned existing technologies. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a battery charger with multiple heat dissipation structures, including a battery charger body, on which heat dissipation structures and waterproof components are provided;

[0006] The heat dissipation structure includes a heat-conducting frame located inside the battery charger body. Multiple sets of heat dissipation fins are installed on the outer wall of the heat-conducting frame, and each set of heat dissipation fins penetrates the battery charger body. A mounting frame is connected to the heat-conducting frame, and a cooling fan is installed on the inner wall of the mounting frame via a bracket.

[0007] The waterproof component includes slots at both ends of the mounting frame, two sets of sealing plates are slidably connected in the slots, adjacent sealing plates are magnetically connected, positioning holes are provided in the slots, fixing cylinders are installed on the sealing plates, and the fixing cylinders are provided with a locking block connected to the positioning hole.

[0008] In a preferred embodiment of the present invention, the heat dissipation structure further includes multiple sets of heat-conducting sheets fixed to the inner wall of the heat-conducting frame, and the cross-section of the heat-conducting frame is inverted U-shaped.

[0009] In a preferred embodiment of the present invention, the waterproof component further includes movable grooves formed on the inner walls of both sides of the groove, and both sets of sealing plates are slidably disposed in the movable grooves.

[0010] In a preferred embodiment of this utility model, a movable rod is vertically inserted into the fixed cylinder, and a sliding plate is fixedly connected to one end of the movable rod facing the sealing plate.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0021] Combination Figures 1 to 3 As shown, this embodiment provides a battery charger with multiple heat dissipation structures, including a battery charger body 10. The battery charger body 10 is provided with a heat dissipation structure 20 and a waterproof component 30. The battery charger body 10 in this embodiment can be a battery charger for electric vehicles. This is an existing component, and the specific model and working principle will not be described here.

[0022] In this embodiment, the heat dissipation structure 20 includes a heat-conducting frame 203 disposed within the battery charger body 10. Multiple sets of heat dissipation fins 205 are installed on the outer wall of the heat-conducting frame 203, and each set of heat dissipation fins 205 penetrates the battery charger body 10. A mounting frame 201 is connected to the heat-conducting frame 203, and a cooling fan 202 is mounted on the inner wall of the mounting frame 201 via a bracket. A vent is provided on the side of the heat-conducting frame 203 near the mounting frame 201. The mounting frame 201 is through-hole for heat dissipation. The mounting frame 201 is fixed within the battery charger body 10. The electrical terminal of the cooling fan 202 is connected to the power supply module within the battery charger body 10 via a wire. The inner side of the heat-conducting frame 203 is in close contact with the heating element within the battery charger body 10, allowing heat from the heating element to be dissipated from multiple directions. The multiple sets of heat dissipation fins 205 dissipate the heat, and in conjunction with the exhaust fan 202, rapid heat dissipation of the battery charger body 10 is achieved, preventing heat loss from the battery charger body 10. The battery charger body 10 is designed to prevent explosion due to high temperature. The waterproof component 30 includes slots 301 at both ends of the mounting frame 201. Two sets of sealing plates 303 are slidably connected in the slots 301. Adjacent sealing plates 303 are magnetically connected. Positioning holes 304 are provided in the slots 301. Fixing cylinders 305 are installed on the sealing plates 303, and the fixing cylinders 305 have locking blocks 310 connected to the positioning holes 304. The left sealing plate 303 has an iron layer, and the right sealing plate 303 has a magnetic layer that is magnetically connected to the iron layer. When the heat dissipation structure 20 is not dissipating heat, the adjacent sealing plates 303 are magnetically connected together to seal the mounting frame 201, preventing water from entering the battery charger body 10 and improving the waterproof performance of the battery charger body 10. When dissipating heat, the adjacent sealing plates 303 slide out and move away from each other. The locking blocks 310 in the fixing cylinders 305 are connected to the positioning holes 304 to fix the position of the sealing plates 303 and prevent the sealing plates 303 from moving and blocking the heat dissipation structure 20 during the heat dissipation process.

[0023] Furthermore, the heat dissipation structure 20 of this embodiment also includes multiple sets of heat-conducting sheets 204 fixed to the inner wall of the heat-conducting frame 203. The cross-section of the heat-conducting frame 203 is inverted U-shaped. The depth of the heat-conducting sheet 204 can be set according to requirements, so that the heat-conducting sheet 204 can fit with the heat-generating element in the battery charger body 10, and facilitate the heat conduction of the heat-generating element in the battery charger body 10.

[0024] Furthermore, the waterproof component 30 of this embodiment also includes a movable groove 302 formed on the inner walls of both sides of the groove 301, and both sets of sealing plates 303 are slidably disposed in the movable groove 302; the movable groove 302 guides the sliding of the sealing plates 303, making it easier for adjacent sealing plates 303 to fit together or move away from each other.

[0025] In this embodiment, a movable rod 307 is vertically inserted into the fixed cylinder 305. A sliding plate 308 is fixedly connected to one end of the movable rod 307 facing the sealing plate 303. A connector 309 is installed on the sliding plate 308 and is fixedly connected to the locking block 310. A through-hole 306 is provided on the sealing plate 303, and the inner diameter of the through-hole 306 is slightly larger than the diameter of the locking block 310. The through-hole 306 is used for the passage of the locking block 310. A spring 312 is sleeved on the outer wall of the movable rod 307. The spring 312 is located between the sliding plate 308 and the inner wall of the fixed cylinder 305. Two sets of guide rods 311 are fixedly connected to the inner wall of the fixed cylinder 305. The sliding plate 308 is slidably disposed on the two sets of guide rods 311. When the heat dissipation structure 20 dissipates heat, the moving rod 307 is pulled up, causing the slide plate 308, connecting piece 309 and locking block 310 to move up and be stored in the fixed cylinder 305. At this time, the spring 312 is in a compressed state, and the sealing plate 303 can slide in the moving groove 302. When the connecting hole 306 is aligned with the positioning hole 304, the moving rod 307 is released, and the compressed spring 312 automatically resets, causing the locking block 310 to move and connect with the positioning hole 304, thus fixing the position of the sealing plate 303 and preventing it from sliding. When the sealing plate 303 needs to be moved again, the operating rod 307 is pulled up to disengage the locking block 310 from the positioning hole 304, and the sealing plate 303 can slide after it is no longer restricted.

[0026] In actual use, when the battery charger body 10 dissipates heat, the two sets of sealing plates 303 of the waterproof component 30 move away from each other within the moving groove 302. At this time, the sliding plate 308, connector 309, and locking block 310 are housed in the fixing cylinder 305, and the spring 312 is compressed, exposing the mounting frame 201 of the heat dissipation structure 20. When the locking block 310 aligns with the positioning hole 304, the compressed spring 312 automatically springs open, connecting the locking block 310 with the positioning hole 304, thus fixing the position of the sealing plate 303. After the cooling fan 202 operates, the heat-conducting plate 204 and heat-conducting frame 203 have a heat-conducting function, which can dissipate heat from the battery charger from multiple directions. The heat from the components is dissipated through the heat dissipation fins 205. With the operation of the cooling fan 202, the heat can be dissipated quickly, preventing the battery charger from exploding due to high temperature and improving the safety of the battery charger. When the battery charger body 10 is not dissipating heat, pulling up the moving rod 307 causes the locking block 310 to disengage from the positioning hole 304. At this time, the sealing plate 303 can slide in the moving groove 302, so that the adjacent sealing plates 303 stick together to seal the opening on the mounting frame 201. The adjacent sealing plates 303 are magnetically attracted together, preventing water from entering the battery charger body 10 when not in use, improving the waterproof performance of the battery charger body 10 and extending its service life.

[0027] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
