Description
Technical Field
[0001] The utility model relates to the technical field of electric vehicle chargers, in particular to a short-circuit-proof electric vehicle charger. Background Art
[0002] With the development of society, traffic congestion and environmental pollution have become very serious. Therefore, electric vehicles that do not cause traffic jams, are easy to park, and do not pollute the environment have begun to become the travel choice of more and more people. Electric vehicles can be seen everywhere, especially on short-distance trips within the city. As the electric vehicle industry has sprung up like mushrooms after rain, the problem of uneven quality has also arisen. Batteries of unqualified quality are very likely to cause hazards such as spontaneous combustion. Even batteries of qualified quality need to be more careful when charging them to prevent damage caused by overheating of the charger or short circuit caused by water immersion.
[0003] When using existing electric vehicle chargers, when it rains or gets humid, rain or fog will penetrate into the interior of the charger through the air outlet, which can easily cause corrosion and short circuit of the charger, reducing the service life of the charger. At the same time, it is also inevitable to place the charger on the ground when charging the electric vehicle, making it easy for the charger to be soaked by rainwater accumulated on the ground in rainy weather, causing safety hazards. In addition, the charger will generate temperature when charging, and the direct contact between the bottom of the charger and the ground will affect the heat dissipation of the charger, avoiding excessive temperature causing the performance of the internal components of the charger to deteriorate, causing the charger body to short-circuit and damage the charger body. Utility Model Content
[0004] The purpose of the present utility model is to provide a short-circuit proof electric vehicle charger to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned objectives, the utility model provides an anti-short-circuit electric vehicle charger, comprising a protective shell, a charger body being placed inside the protective shell, charging cables being fixedly connected at both ends of the charger body, and the charging cables passing through the interior of the protective shell, a protective cover being provided below the protective shell, a clamping device being provided on one side of the protective cover, the clamping device being used to protect the charger body, the clamping device comprising a circular plate fixedly connected to both sides of the inner wall of the protective shell, a plurality of equally spaced fixed blocks being fixedly connected to adjacent sides of the two circular plates, the outer wall of the circular plate being slidably connected to the inner wall of the protective cover, a movable plate being provided on one side of the protective cover, a No. 1 clamping plate being slidably connected at both ends of the movable plate, the width of the No. 1 clamping plate being adapted to the distance between the two adjacent fixed blocks, a supporting device being provided below the protective cover, the supporting device being used to lift the position of the protective shell.
[0006] As a further improvement of the present technical solution, one side of the protective shell is fixedly connected to a mounting block, the interior of the mounting block is rotatably connected to a disc, one end of the disc is fixedly connected to a pull rod, one side of the movable plate is fixedly connected to one end of the disc, and the interior of the movable plate is slidably connected to both sides of the mounting block.
[0007] As a further improvement of the present technical solution, cylindrical blocks are fixedly connected inside both ends of the movable plate, and a spring is fixedly connected to one end of the cylindrical block and the end of the first clamping plate away from the circular plate.
[0008] As a further improvement of this technical solution, the lower side of the No. 1 clamping plate is fixedly connected to the No. 2 clamping plate, and the No. 1 clamping plate and the No. 2 clamping plate are both provided with inclined surfaces on one side close to the circular plate, and the directions of the inclined surfaces are opposite.
[0009] As a further improvement of the present technical solution, the support device includes two support legs rotatably connected to the lower side of the protective cover, and the two support legs are symmetrically arranged. Two snaps are fixedly connected to the lower side of the protective cover, and the snaps are snap-fitted to the support legs.
[0010] As a further improvement of this technical solution, two ventilation plates are provided on the lower side of the protective shell, dustproof plates are fixedly connected to the inner walls on both sides of the protective shell, and multiple inclined plates are fixedly connected to both sides of the protective shell, and the inclined plates are provided on the outside of the dustproof plates.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. When the protective cover is opened, the No. 2 clip plate is located between the two fixed blocks, and the charger body is placed inside the protective shell. Then the pull rod is rotated to drive the disc to rotate, and the rotation of the disc drives the movable plate to move downward. At this time, the No. 1 clip plate is located between the two fixed blocks. Since one side of the No. 1 clip plate is an inclined surface, the protective cover drives the No. 1 clip plate to continuously cross several fixed blocks. When the protective cover moves to the appropriate position, the No. 1 clip plate is driven to be clamped between the two adjacent fixed blocks under the reaction force of the spring, thereby realizing rapid installation between the protective cover and the protective shell, which is convenient for protecting the charger body. At the same time, the protective cover is arranged under the protective shell to effectively prevent rainwater from entering the interior of the charger body. With the use of the inclined plate and the dustproof plate, the purpose of waterproofing and heat dissipation is achieved, which is beneficial for the device to reduce corrosion and short circuit of the charger body caused by rainwater intrusion, thereby improving the service life of the charger body.

Lift the device by the supporting legs to avoid direct contact with the ground and reduce the impact of water on the ground on the charger. At the same time, lifting the device is conducive to ventilation and heat dissipation inside the protective shell, avoiding excessive temperature causing performance degradation of internal components of the charger body, causing a short circuit in the charger body, and causing damage to the charger body.
