Technical Field

[0001] This utility model relates to the field of charger technology, and in particular to a charger with an automatic overheat protection function. Background Technology

[0002] Chargers can be categorized into low-frequency and high-frequency chargers based on their circuit operating frequency. Low-frequency chargers are designed using traditional analog circuit principles, and their internal electrical components are relatively large. They generally produce less noise when operating under heavy loads, but they are more resistant to harsh power grid conditions and have higher reliability and stability than high-frequency chargers. However, prolonged use can lead to overheating, which can cause damage or even explosion. Therefore, users need to ensure that their chargers have automatic power-off protection.

[0003] In summary, traditional chargers tend to overheat after prolonged use and lack automatic overheat protection, posing a safety hazard to users. Therefore, a charger with automatic overheat protection is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to provide a charger with an automatic overheat protection function to solve the problem mentioned in the background art that when users use the charger, the temperature will become too high after long-term use, and the charger cannot automatically cut off the power when the temperature is too high, which will lead to safety hazards and affect the personal safety of users.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a charger with overheat automatic power-off protection function, including a charger bottom shell assembly, a heat dissipation protection mechanism is attached to the upper surface of the charger bottom shell assembly, a terminal output wire assembly is connected to the inner ring surface of the heat dissipation protection mechanism, and a positioning and mounting component is fitted onto the bottom outer ring surface of the charger bottom shell assembly.

[0006] The heat dissipation protection mechanism includes a protective plate, a limiting block, a snap-fit ​​plate, a cover plate, a protective shell, a charger mechanism assembly, a voltage setting controller, an automatic trip power-off structure assembly, a system control main board, a connecting block, a motor, fan blades, and a return spring. A protective plate is mounted on the side surface of the heat dissipation protection mechanism. A protective shell is snap-fitted onto the inner ring surface of the heat dissipation protection mechanism. A motor is mounted on the inner ring surface of the protective shell.

A voltage setting controller is mounted on the bottom surface of the charger mechanism assembly. A system control main board is mounted on the side surface of the charger mechanism assembly. A return spring is fixedly connected to the inner ring surface of the cover plate. A limiting block is mounted on the side surface of the return spring.

[0007] Preferably, the upper surface of the positioning and mounting component is provided with a positioning opening, and the positioning opening is opened around the positioning and mounting component as the center point.

[0008] Preferably, the upper surface of the snap-fit ​​plate has a heat dissipation opening, and the number of heat dissipation openings is multiple.

[0025] Please see Figure 1-7This utility model provides a technical solution: a charger with overheat automatic power-off protection function, including a charger bottom shell assembly 1, a heat dissipation protection mechanism 3 attached to the upper surface of the charger bottom shell assembly 1, a terminal output wire assembly 4 connected to the inner ring surface of the heat dissipation protection mechanism 3, and a positioning and mounting component 2 fitted to the bottom outer ring surface of the charger bottom shell assembly 1. The heat dissipation protection mechanism 3 includes a protective plate 301, a limiting block 302, a snap-fit ​​plate 303, a cover plate 306, a protective shell 307, a charger mechanism assembly 308, a voltage setting controller 309, an automatic trip power-off structure assembly 310, and a system. The system includes a main control board 311, a connecting block 312, a motor 313, a fan blade 314, and a return spring 315. A protective plate 301 is mounted on the side surface of the heat dissipation protection mechanism 3. A protective shell 307 is snapped onto the inner ring surface of the heat dissipation protection mechanism 3. A motor 313 is mounted on the inner ring surface of the protective shell 307. A fan blade 314 is fixedly sleeved at the top of the output shaft of the motor 313. A charger mechanism assembly 308 is welded to the inner ring surface of the heat dissipation protection mechanism 3. A voltage setting controller 309 is mounted on the bottom surface of the charger mechanism assembly 308. A return spring 315 is mounted on the side surface of the charger mechanism assembly 308. The system control motherboard 311 has a return spring 315 fixedly connected to the inner ring surface of the cover plate 306. A limit block 302 is installed on the side surface of the return spring 315. In use, the system control motherboard 311 can transmit data to the voltage setting controller 309, which then turns on the set motor 313. After the motor 313 starts, it can drive the set fan blade 314 to rotate. Through the set snap-fit ​​plate 303 and the multiple heat dissipation openings 304 on the snap-fit ​​plate 303, the user can control the charger at a medium temperature. To minimize the impact on users, when the charger temperature reaches a high level, the system control motherboard 311 transmits data to the voltage setting controller 309. The voltage setting controller 309 then opens the automatic trip power-off structure assembly 310, allowing the user to automatically cut off power when the charger overheats. After the user presses the limit block 302 and holds it in place, the user can pull up the cover 306, allowing the user to perform regular maintenance on the charger mechanism assembly 308 and the system control motherboard 311.

[0026] Furthermore, the upper surface of the positioning and mounting component 2 is provided with a positioning opening 201, and the positioning opening 201 is opened around the positioning and mounting component 2 as the center point. The positioning opening 201, which is opened around the positioning and mounting component 2 as the center point, makes it convenient for the user to use and install the positioning and mounting component 2 as a whole with bolts.

[0027] Furthermore, the upper surface of the snap-fit ​​plate 303 is provided with a heat dissipation opening 304, and there are multiple heat dissipation openings 304. The multiple heat dissipation openings 304 facilitate the user to dissipate heat inside the heat dissipation protection mechanism 3.

[0028] Furthermore, the motor 313 is connected to the protective shell 307 via the connecting block 312, and the connecting block 312 is arranged around the motor 313 as the center point. The connecting block 312 arranged around the motor 313 as the center point makes it easy for the user to stably connect the motor 313 to the protective shell 307.

[0029] Furthermore, a limiting plate 202 is installed on the bottom surface of the charger bottom housing assembly 1, and the limiting plate 202 and the positioning mounting component 2 are structurally compatible.

The limiting opening 316, which is matched in size with the limiting block 302, can facilitate the user to use the limiting block 302 for limiting.

[0031] Furthermore, a stop 305 is installed on the upper surface of the heat dissipation protection mechanism 3, and there are multiple stops 305 that limit the use of the cover plate 306. The multiple stops 305 that limit the use of the cover plate 306 make it convenient for the user to limit the use of one side of the cover plate 306.

[0032] Working principle: When the user uses the charger, when the charger temperature reaches the medium setting, the system control motherboard 311 transmits data to the voltage setting controller 309. The voltage setting controller 309 then turns on the motor 313. After the motor 313 starts, it drives the fan blades 314 to rotate. Through the mounting plate 303 and the multiple heat dissipation openings 304 on it, the user can continue to use the charger at the medium temperature, reducing the impact on the user. When the charger temperature reaches the high setting, the system control motherboard 311 transmits data to the voltage setting controller. In step 309, the voltage setting controller 309 can then open the automatic trip power-off structure assembly 310, allowing the user to automatically cut off power when the charger overheats. After the user presses the limit block 302 and presses it into place, the user can pull the cover plate 306 upwards, allowing the user to perform regular maintenance on the charger mechanism assembly 308 and the system control motherboard 311. Through the positioning mounting component 2 and the multiple positioning openings 201 through the front surface of the positioning mounting component 2, the user can easily insert bolts into the positioning openings 201 to install and use the charger.
