However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an intelligent high-frequency charger with a durable protective shell, including a base plate 1. A cover plate 2 is provided on the top surface of the base plate 1. The cover plate 2 is made of flame-retardant PC material. A reinforcing support rod 5 is provided inside the cover plate 2. The bottom surface of the reinforcing support rod 5 is fixedly connected to the top surface of the base plate 1. The cover plate 2 and the reinforcing support rod 5 are connected by screws. A positioning rod 26 is fixedly connected to the inner top surface of the cover plate 2. The positioning rod 26 is inserted into the top surface of the reinforcing support rod 5. Connecting grooves 11 are provided on both outer walls of the base plate 1. A locking block 14 is fixedly connected to the inner wall of the connecting groove 11. A locking plate 21 is fixedly connected to the bottom surface of the cover plate 2. The locking plate 21 is inserted into the connecting groove 11 and engages with the locking block 14. A high-frequency transformer assembly 3 is installed at the center of the top surface of the base plate 1. The high-frequency transformer assembly 3 has a built-in protocol chip that automatically identifies the charging protocol and power requirements supported by the device, dynamically adjusts the output voltage and current, and provides overvoltage / overcurrent / short circuit protection.

[0023] The specific settings and functions of this embodiment are described in detail below. By using the insertion of the positioning rod 26 and the wire harness sleeve 25, the reinforcing support rod 5 provides reinforced support to the four internal corners of the cover plate 2, thereby improving the overall strength of the cover plate 2 and enhancing the impact resistance of this utility model. It is not easy to deform or break when it is hit. By using the snap-fit ​​plate 21 and the snap-fit ​​block 14, it is easier to connect and fix the cover plate 2 and the base plate 1, which makes it easier to avoid shaking and displacement when connecting to the reinforcing support rod 5 with screws.

[0024] Example 2: Figure 1 - Figure 4As shown, a limiting groove 17 is provided on the top surface of the base plate 1, and an insulating pad 18 is fixedly connected to the inner wall of the limiting groove 17. The high-frequency transformer assembly 3 is set on the top surface of the insulating pad 18. Limiting slide grooves 15 are provided on both sides of the limiting groove 17. The limiting slide grooves 15 are opened on the top surface of the base plate 1. A pressure plate 4 is movably connected to the inner wall of the limiting slide groove 15. One side of the pressure plate 4 is snapped into the outer edge of the high-frequency transformer assembly 3. A spring 16 is connected between the bottom end of the pressure plate 4 and the inner wall of the limiting slide groove 15. A wiring slot 22 is installed on the outer wall of one end of the cover plate 2. A ventilation hole 23 is provided on one side of the wiring slot 22.

An installation hole 12 is opened through the top surface of the base plate 1.

[0025] The overall effect of this embodiment is that the pressure plates 4 at both ends of the high-frequency transformer assembly 3 provide pressure and limit, which facilitates quick connection of the high-frequency transformer assembly 3 during maintenance by moving the pressure plates 4 within the limiting groove 15, thus shortening the maintenance time. The heat dissipation plate 13 facilitates better heat dissipation. The insulating pad 18 provides insulation protection for the bottom of the high-frequency transformer assembly 3 and provides a certain amount of buffer protection to prevent the high-frequency transformer assembly 3 from being damaged by impact.

[0026] The device's usage and working principle are as follows: During use, it is connected to an external power source via the wiring slot 22. The built-in protocol chip of the high-frequency transformer assembly 3 automatically identifies the charging protocol and power requirements supported by the device, dynamically adjusting the output voltage and current. It also provides overvoltage / overcurrent / short-circuit protection. The insertion of the positioning rod 26 into the cable tie sleeve 25 provides reinforced support to the four internal corners of the cover plate 2, thereby improving the overall strength of the cover plate 2 and enhancing its impact resistance. The engagement of the locking plate 21 with the locking block 14 facilitates easier connection and fixation between the cover plate 2 and the base plate 1, preventing shaking or displacement when connected to the reinforcing rod 5 with screws. The pressure plates 4 at both ends of the high-frequency transformer assembly 3 provide pressure limit, allowing for quick disconnection of the high-frequency transformer assembly 3 during maintenance by moving the pressure plates 4 within the limit groove 15, shortening maintenance time. The heat dissipation plate 13 facilitates better heat dissipation.
