Electric bicycles have gained popularity due to their affordability, convenience, and environmental friendliness. Currently, electric bicycles require a dedicated charger for charging. This charger is specifically designed for the electric bicycle battery. Electric bicycles generally use a three-stage charger: a constant current stage, a constant voltage stage, and a trickle charge stage.

[0003] For example, the utility model with application number 202222169595.6 relates to the field of charger processing technology. This utility model uses a winding column connected to the lower surface of the charger body. The power cords on both sides of the charger body can be wound around the winding column. A placement plate is used to place the supporting connecting wires. The bolt passes through the inside of the fixing tube and rotates with the threaded hole to limit the connecting wires on the winding column, thereby achieving the effect of effectively processing the connecting wires on the electric bicycle charger. However, existing electric bicycle chargers only have outer shell protection during use, and the protection effect is not good, making the charger easy to be damaged.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an electric bicycle charger with a built-in safety isolation structure. Utility Model Content

[0022] like Figure 1 and Figure 2 As shown, an electric bicycle charger with a built-in safety isolation structure includes a housing 1 and an inner isolation component 3. An inner support frame 2 is installed on the inner wall of the housing 1. The inner support frame 2 contacts the side surface of the inner partition box 301, providing a supporting function and further limiting the inner partition box 301. The inner isolation component 3, used for the safe isolation of internal components, is disposed inside the housing 1. The inner isolation component 3 includes an inner partition box 301, an adjusting box 302, a cooling fan 303, an inner divider box 304, and a ventilation opening 305. The adjusting box 302 is disposed inside the inner partition box 301. The inner partition box 301 further divides the space inside the housing 1, providing additional protection for the internal circuit board of the charger and preventing external rainwater from entering and damaging the circuit board. The adjusting box 302 slides inside the inner partition box 301 according to the size of the circuit board. The size is adjustable, and a cooling fan 303 is provided in the middle of the top of the adjustment box 302. The cooling fan 303 on one side rotates inside the charger to promote cooling and prevent the charger from overheating and affecting its use. An inner compartment 304 is connected inside the adjustment box 302. The inner compartment 304 and the ventilation port 305 play a role in equalizing airflow and making the heat dissipation inside the charger even. The inner compartment 304 has a ventilation port 305 on its side. A top plate 4 is installed at the top of the device box 1, and limit plates 5 are installed on both sides of the bottom inside the device box 1. The limit plates 5 play a role in limiting the inner compartment 301. A pad plate 6 is installed in the middle of the bottom inside the device box 1, and charging cables 7 are installed at both ends of the outside of the device box 1. Heat dissipation holes 8 are opened on the front and rear sides of the device box 1. The heat dissipation holes 8 are used to dissipate the heat inside the charger. The device box 1 and the heat dissipation holes 8 are an integrated structure.

[0023] like Figure 3As shown, a sealing plate 9 is provided inside the heat dissipation hole 8. The sealing plate 9 seals the heat dissipation hole 8 when the charger is not in use, preventing dust from entering the casing 1 and affecting its service life. The size of the sealing plate 9 is larger than the size of the heat dissipation hole 8. An auxiliary component 10 for auxiliary control is provided on the surface of the sealing plate 9. There are two sets of auxiliary components 10. The auxiliary component 10 includes a connecting rod 1001 and a rotating rod 1002. The rotating rod 1002 is installed at the end of the connecting rod 1001.

[0024] In summary, this electric bicycle charger with a built-in safety isolation structure is first based on... Figures 1-3 The structure shown allows the internal circuit board and other components of the charger to be installed inside the inner compartment 301. During installation, the adjusting box 302 slides inside the inner compartment 301 to adjust the size according to the circuit board dimensions. At this time, the inner compartment 301 further divides the space inside the charger box 1, providing additional protection for the internal circuit board and preventing damage from external rainwater. When the charging box is in use, a cooling fan 303 on one side rotates inside the charger to promote cooling and prevent overheating, which could affect its use. The inner compartment 304 and the... Vent 305 serves to distribute airflow evenly, ensuring uniform heat dissipation inside the charger. The hot air generated during charger use is then exhausted through the heat dissipation hole 8 on the side of the charger box 1. To exhaust the hot air, the control lever 1004 must be held to rotate the rotating rod 1002 and make the connecting rod 1001 horizontal. Then, the connecting rod 1001 is pushed to move the sealing plate 9 towards the inward support frame 2. The heat dissipation hole 8 is connected to the inside of the charger box 1 for heat dissipation. When not in use, the sealing plate 9 seals the heat dissipation hole 8 to prevent dust from entering the charger box 1 and affecting its service life.
