Problems solved by technology

[0002] Electric vehicle charger is a charging device specially configured for the battery of electric bicycles. The classification of chargers: with and without power frequency 50 Hz transformers, can be divided into two categories. Freight three-wheel chargers are generally used with power frequency Transformer chargers are bulky, heavy, and expensive, but reliable and cheap; electric bicycles and electric motorcycles use so-called switching power supply chargers, which save electricity and have high efficiency, but are easy to break
The electric vehicle chargers of the prior art have the following two disadvantages when in use: one is that the heat is difficult to dissipate during the charging process of the charger, which will lead to a reduction in the service life of the charger and low charging efficiency; the other is that it is difficult to repair and disassemble the charger when it fails

Embodiment 1

[0038] like Figure 1-4 As shown, the present invention provides an energy-saving self-protecting electric vehicle charger, comprising a first casing 1, a second casing 2 is arranged on the rear side of the first casing 1, and a fan is arranged in the middle of the front wall of the first casing 1 5. Mounting seats 17 are fixedly connected to the middle of the bottom walls of the first shell 1 and the second shell 2. The tops of the two sets of mounting seats 17 are provided with a charger main body 16, and the top wall of the charger main body 16 is fixedly connected with a heat dissipation box 14. The top wall of the heat dissipation box 14 penetrates through and is fixedly connected with a plurality of groups of evenly distributed heat dissipation fins 13, and the bottom of the heat dissipation fins 13 is penetrated by the heat pipe 15. When the electric vehicle is charged by this charger, the charger main body 16 works to generate heat, The heat is absorbed by the heat pip...

Embodiment 2

[0040] In this embodiment, on the basis of the structural arrangement disclosed in Embodiment 1, connecting blocks 7 are fixedly connected to the upper and lower rear ends of the left and right side walls of the first housing 1, and the middle part of the rear wall of the connecting block 7 is provided with a slot 18. The insertion block 11 is slidably connected inside the slot 18. The upper and lower sides of the insertion block 11 are provided with installation cavities 19. A side wall of the installation cavity 19 away from the slot 18 is fixedly connected with a spring 22, and the spring 22 is close to the end of the slot 18. Both are fixedly connected with the blocking block 21. When the charger main body 16 fails, the buttons 6 on both sides are pressed to move the button 6 to the blocking block 21, so that the blocking block 21 is squeezed into the interior of the installation cavity 19, so that the card The block 21 is released from the slot 20, and the second housing 2...

Embodiment 3

[0042] In this embodiment, on the basis of the structural arrangement disclosed in the above-mentioned embodiment, the clamping blocks 21 penetrate through and are slidably connected to the side wall of the installation cavity 19 close to the slot 18 , and the clamping blocks 21 are slidably connected to the interior of the clamping slot 20 on the side away from the spring 22 . , so that the card block 21 can be retracted into the installation cavity 19 and can extend out of the installation cavity 19 with the reset of the spring 22. The card slots 20 are respectively arranged on the upper and lower parts of the front end of the slot 18, and the insert blocks 11 are fixedly connected to the fixed block. 4. In the middle of the front wall, the fixing blocks 4 are fixedly connected to the upper and lower ends of the front part of the left and right side walls of the second casing 2 respectively. 2. The upper and lower side walls are provided with a plurality of groups of evenly d...

Abstract

The invention relates to the field of electric vehicle chargers, and discloses and provides an energy-saving self-protection electric vehicle charger which comprises a first shell, a second shell is arranged on the rear side of the first shell, a fan is arranged in the middle of the front wall of the first shell, and mounting bases are fixedly connected to the middle of the bottom wall of the first shell and the middle of the bottom wall of the second shell. A charger main body is arranged at the tops of the two mounting seats, a heat dissipation box is fixedly connected to the top wall of the charger main body, and a plurality of groups of uniformly distributed heat dissipation fins penetrate through and are fixedly connected to the top wall of the heat dissipation box. According to the invention, the charger main body works to generate heat, the heat is absorbed by the heat conduction pipe and then is dissipated into the shell through the cooling fins, and then the fan is started, so that air flow generated when the fan works is dissipated into external air through the cooling holes in the second shell; and the heat dissipation efficiency of the charger is greatly improved, so that the service life of the charger is greatly prolonged.

Description

technical field [0001] The invention relates to the field of electric vehicle chargers, in particular to an energy-saving self-protection electric vehicle charger. Background technique [0002] The electric vehicle charger is a charging device specially configured for the battery of the electric bicycle. The classification of the charger: it can be divided into two categories with and without a power frequency 50 Hz transformer. The freight three-wheeled charger is generally used with a power frequency. Transformer chargers are bulky, heavy, and power-hungry, but are reliable and cheap; electric bicycles and electric motorcycles use so-called switching power supply chargers, which save power and have high efficiency, but are easy to break. The electric vehicle chargers in the prior art have the following two disadvantages: one is that the heat is difficult to dissipate during the charging process of the charger, which reduces the service life of the charger and the charging ...
