This utility model aims to facilitate the storage of the data cable while reducing the overall size of the vehicle charger.

[0004] However, this device also has the following drawbacks:

[0005] When a car charger charges multiple devices simultaneously or charges devices that support fast charging, the power components inside the car charger generate a lot of heat as they handle large currents and power. Excessive temperature may accelerate the aging of the electronic components inside the car charger, shortening the charger's lifespan. It may also damage the batteries of the electronic devices being charged, reducing their range and lifespan. More seriously, overheating may cause charger malfunctions or even fires. This device does not solve this problem. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] A modular on-board charger with temperature adaptive protection includes an on-board charger body 1 and a top mount 2. The top mount 2 is fixedly installed on the top of the on-board charger body 1. Two sets of charging ports 6 are provided on the other side of the top of the top mount 2. The charging ports 6 are fixedly connected to the top mount 2. The device also includes a heat dissipation component, which includes a cooling fan 3. The cooling fan 3 is installed on one side of the top surface of the top mount 2. A temperature sensor 7 is installed on one side of the surface of the on-board charger body 1. The temperature sensor 7 is fixedly connected to the on-board charger body 1. The cooling fan 3 and the temperature sensor 7 are electrically connected to the main control circuit board inside the on-board charger body 1.

[0027] By setting temperature sensor 7, the operating temperature of the vehicle charger body 1 can be monitored and the temperature information can be transmitted to the main control circuit board. When the temperature is higher than the optimal operating temperature range of the vehicle charger body 1, the main control circuit board will turn on the cooling fan 3. The cooling fan 3 can accelerate the airflow and quickly remove the heat generated by the vehicle charger body 1, preventing its performance from deteriorating or malfunctioning due to excessive temperature. The temperature of the vehicle charger body 1 can be controlled within a reasonable range, extending the service life of the vehicle charger body 1.

[0028] It also includes an ejection module 4, which includes an ejection rod 401. A limiting plate 402 is fixedly installed on the top of the ejection rod 401. The ejection rod 401 and the limiting plate 402 are slidably installed inside the mounting sleeve 403. A spring 404 is slidably installed inside the mounting sleeve 403. The bottom of the spring 404 abuts against the top of the limiting plate 402, and the top of the spring 404 abuts against the top inner wall of the mounting sleeve 403. Two sets of locking blocks 405 are provided on both sides of the limiting plate 402, and two sets of locking grooves 406 are provided on both sides of the mounting sleeve 403. The locking blocks 405 and the locking grooves 406 are slidably engaged. One side of the locking block 405 is fixed. A permanent magnet 407 is installed, with the two sets of permanent magnets 407 facing opposite magnetic poles toward the electromagnet 409. The snap-fit ​​block 405 and the permanent magnet 407 are slidably installed in the mounting groove 408 inside the limiting plate 402. An electromagnet 409 is provided on one side of the permanent magnet 407. The electromagnet 409 is electrically connected to the commutator integrated on the main control circuit board inside the vehicle charger body 1. The magnetic pole of the electromagnet 409 faces the permanent magnet 407. The electromagnet 409 is fixedly installed in the mounting groove 408. The ejector module 4 is installed inside the top seat 2. Two sets of through holes 5 are opened at the bottom of the top seat 2. The ejector rod 401 is slidably engaged with the through holes 5.

[0029] By setting up the electromagnet 409, the direction of the current passing through the electromagnet 409 can be changed by the commutator integrated on the main control circuit board, thereby changing the direction of the magnetic poles of the electromagnet 409. When used in conjunction with the permanent magnet 407, it can push the latching block 405 outward to latch with the latching slot 406, or pull the latching block 405 out of the latching slot 406. This ensures that the ejector rod 401 is retracted inside the mounting sleeve 403 when the vehicle charger body 1 is working normally. When the temperature is higher than the maximum operating temperature, the ejector rod 401 can be pushed out downward by the compressed spring 404 to push the vehicle charger body 1 out of the car interface, preventing continued operation from causing malfunctions or even fires.

[0030] In practical use, move the device to the designated position, align the car charger body 1 with the external car interface and insert it. The electronic device can then be charged through the charging port 6. During the insertion of the car charger body 1 into the car interface, the push rod 401 is pushed back into the mounting sleeve 403 by both sides of the car interface, compressing the spring 404. Simultaneously, the commutator integrated on the main control circuit board controls the current to flow forward through the limiting coil of the electromagnet 409, causing the electromagnet 409 to push the permanent magnet 407 outward. The permanent magnet 407 then pushes the locking block 405 outward. When the locking block... When block 405 aligns with slot 406, it automatically enters slot 406 and locks push rod 401. When temperature sensor 7 detects that the operating temperature of the vehicle charger body 1 is higher than the maximum operating temperature, the commutator integrated in the main control circuit board inside the vehicle charger body 1 changes the current direction of electromagnet 409, causing the magnetic poles to reverse. This, through magnetic attraction, drives two sets of permanent magnets 407 to move into the mounting slot 408, causing block 405 to push from slot 406. The compressed spring 404 pushes push rod 401 downward, thereby pushing the vehicle charger body 1 out of the car socket.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
