Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle chargers, and more particularly to an electric vehicle charger with a waterproof function. Background Art

[0002] An electric vehicle charger is a device used to charge an electric vehicle's battery. Its primary function is to convert alternating current (AC) into the direct current (DC) required by the electric vehicle's battery for charging. Generally speaking, electric vehicle chargers are crucial for ensuring the proper functioning of electric bicycles. However, they still have some drawbacks in practical use. For example, electric vehicles are often parked outdoors for charging. To dissipate heat, chargers have cooling holes on their casings. If it rains, water can enter the charger through these holes, potentially causing leakage and potentially leading to safety hazards such as short circuits.

[0003] Therefore, an electric vehicle charger with a waterproof function is proposed to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide an electric vehicle charger with a waterproof function to solve the problem in the prior art that rainwater can enter the interior of the charger through the heat dissipation holes, thereby causing leakage, resulting in safety hazards such as short circuits.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a waterproof electric vehicle charger, comprising

[0006] protective housing;

[0007] Heat dissipation vents are provided at the front and rear of the protective housing;

[0008] Rainproof components, which are arranged in front and behind the protective shell;

[0009] A charger body, the charger body being fixedly mounted inside the protective housing;

[0010] A disassembly assembly component, wherein the disassembly assembly component is arranged on the top of the protective shell;

[0011] The rainproof assembly includes a baffle, a slide groove, a spring, a pull groove, a magnetic strip, and a metal strip. The slide groove is opened inside the protective shell, the two sides of the baffle are slidingly connected to the inside of the slide groove, the top of the spring is fixedly connected to the inside of the protective shell, the bottom end of the spring is fixedly connected to the top of the baffle, the pull groove is opened on the front of the baffle, the magnetic strip is fixedly installed on the bottom of the baffle, and the metal strip is fixedly installed on the inner surface of the baffle.

[0012] The disassembly and assembly component includes a box cover and a handle. The box cover is installed on the top of the protective shell, and the disassembly and assembly component is fixedly installed on the top of the box cover.

[0013] It also includes a heat dissipation component, which is arranged inside the protective shell.

[0014] Among them, the heat dissipation assembly includes a heat conductive block, a water cooling pipe, a water guide hopper, a filter, and a connecting plate. The heat conductive block is fixedly installed inside the protective shell, the top of the heat conductive block is detachably connected to the bottom of the charger body, the outer surface of the water cooling pipe is fixedly connected to the inside of the heat conductive block, the outer surface of the water cooling pipe is fixedly connected to the inside of the protective shell, the bottom of the water guide hopper is fixedly connected to one end of the water cooling pipe, the filter is detachably installed on the top of the water guide hopper, one end of the connecting plate is fixedly connected to the outer surface of the water guide hopper, and the other end of the connecting plate is fixedly connected to the outer surface of the protective shell.

[0015] The beneficial effects of the above technical solution of the utility model are as follows:

[0016] In the above scheme, a protective shell, a heat dissipation vent, a rainproof component, a charger body, and a disassembly and assembly component are provided. When the charger body is used to charge the electric vehicle on rainy days, the baffle is pulled downward using the pull groove to slide the baffle in the protective shell until the magnetic strip and the metal strip are attracted to each other, so that the baffle completely covers the heat dissipation vent. At this time, the spring is in a stretched state. When it is not raining, the baffle is pulled upward through the pull groove to separate the magnetic strip from the metal strip. Under the action of the spring tension, the baffle slides upward to open the heat dissipation vent. Through the above structure, the heat dissipation vent is blocked when used on rainy days to prevent rainwater from entering the interior of the charger body through the heat dissipation vent, thereby preventing a short circuit.

[0017] A heat dissipation component is set up. When used on rainy days, rainwater will flow into the water cooling pipe through the water guide bucket. The heat conductive block will absorb the heat generated when the charger body is running, and the rainwater will flow through the heat conductive block under the action of gravity and take away the heat in the heat conductive block. Finally, the rainwater will be discharged from one end of the water cooling pipe. Through the above structure, the heat is dissipated by rainwater after the heat dissipation port is blocked, thereby achieving the effect of preventing heat accumulation.

[0036] The rainproof component 3 includes a baffle 31, a slide groove 32, a spring 33, a pull groove 34, a magnetic strip 35, and a metal strip 36. The slide groove 32 is opened inside the protective shell 1, and both sides of the baffle 31 are slidingly connected to the inside of the slide groove 32. The top of the spring 33 is fixedly connected to the inside of the protective shell 1, and the bottom end of the spring 33 is fixedly connected to the top of the baffle 31. The pull groove 34 is opened on the front of the baffle 31, the magnetic strip 35 is fixedly installed at the bottom of the baffle 31, and the metal strip 36 is fixedly installed on the inner surface of the baffle 31.

[0038] It also includes a heat dissipation component 6, which is arranged inside the protective shell 1.

[0039] Among them, the heat dissipation component 6 includes a heat conductive block 61, a water cooling pipe 62, a water guide hopper 63, a filter 64, and a connecting plate 65. The heat conductive block 61 is fixedly installed inside the protective shell 1, and the top of the heat conductive block 61 is detachably connected to the bottom of the charger body 4. The outer surface of the water cooling pipe 62 is fixedly connected to the inside of the heat conductive block 61, and the outer surface of the water cooling pipe 62 is fixedly connected to the inside of the protective shell 1.

One end of the connecting plate 65 is fixedly connected to the outer surface of the water guide hopper 63, and the other end of the connecting plate 65 is fixedly connected to the outer surface of the protective shell 1.

[0040] Among them, the suction force between the magnetic strip 35 and the metal strip 36 is greater than the tension of the spring 33, so that the magnetic strip 35 and the metal strip 36 will not be separated due to the tension of the spring 33 when they are attracted to each other; the box cover 51 can be opened to facilitate the inspection of the charger body 4; the connection between the disassembly and assembly component 5 and the protective shell 1 and the connection between the charger body 4 wires and the protective shell 1 are both provided with sealing rings to effectively prevent rainwater from seeping in through the gaps.
