[0023] Embodiment:
[0024] As shown in the attached Figure 1 to the attached Figure 4 figure:
[0025] The utility model provides a vehicle-mounted charger, which includes a charger main body 1. The charger main body 1 includes a vehicle-mounted power connector 2 and a charging head 3. The bottom end of the vehicle-mounted power connector 2 is provided with a positive electrode head 4. Negative electrode elastic pieces 5 are arranged on both sides of the vehicle-mounted power connector 2. One side of the charging head 3 is fixedly connected with a spiral connecting wire 6. One end of the spiral connecting wire 6 is connected with a terminal head 7. The other side of the charging head 3 is fixedly connected with a fixing component 8 for fixing the terminal head 7. Two groups of installation grooves 10 are opened at the top end of the charging head 3. Sealing and limiting components 9 are arranged inside the installation grooves 10. The sealing and limiting components 9 include a baffle 901 vertically installed at the center of the installation groove 10. Guide rods 902 are fixedly connected to both sides of the installation groove 10 on both sides of the baffle 901.
[0026] Among them, the fixing component 8 includes a fixing seat 801 arranged on the outer surface of the charging head 3. A placement groove 802 is opened on one side of the fixing seat 801. A receiving groove 803 adapted to the terminal head 7 is opened inside the placement groove 802. A magnetic attachment is arranged outside the receiving groove 803, and the terminal head 7 has magnetism, which can fix the terminal head 7 and prevent the situation that the terminal head 7 is damaged when the data cable is stepped on by the foot.
[0027] Among them, USB interfaces 11 are arranged inside the two groups of installation grooves 10. USB contacts are fixedly connected inside the two groups of USB interfaces 11.
[0028] Among them, the other side of the guide rod 902 is fixedly connected to the inner wall of the installation groove 10. Fixing frames 903 are slidably connected to the outer sides of the guide rods 902. A receiving groove is arranged between the two groups of fixing frames 903. Through the arranged receiving groove, stable limiting and clamping of the connector of the data cable can be achieved, and loosening between the data cable and the fixing frame 903 can be avoided when the vehicle bumps and when people accidentally pull the data cable.
[0029] Among them, a spring 904 is sleeved on one side of the guide rod 902. The two ends of the spring 904 are respectively abutted against the installation groove 10 and the fixing frame 903.
[0030] Among them, push plates 905 are fixedly connected to the tops of the fixing frames 903, and the cross section of the push plates 905 is in a trapezoidal structure. A circular groove 906 is opened at the top of the fixing frame 903. One side of the circular groove 906 extends to the outside of the push plate 905, and the other side of the circular groove 906 penetrates through to the inside of the receiving groove, which is convenient for the data cable to be hermetically fitted and plays a role in dust prevention.
[0031] Among them, a plurality of heat dissipation holes 12 are opened on one side of the vehicle-mounted power connector 2, and the heat dissipation holes 12 are symmetrically arranged with respect to the central axis of the charger main body 1, which prevents the components inside the vehicle-mounted charger from overheating and being unable to work normally, and extends the service life of the vehicle-mounted charger.
[0032] Working principle of this embodiment:
[0033] When the vehicle-mounted charger is needed, the user inserts the vehicle-mounted charger into the cigarette lighter socket and holds the connector of the external data cable to align with the USB interface 11. At this time, the connector of the external data cable contacts the push plate 905. Since the push plate 905 is arranged in a trapezoidal structure, as the connector of the external data cable moves downward, through the inclined surface of the push plate 905, a thrust force for moving the fixing frame 903 to both sides is applied. At this time, the fixing frame 903 slides inside the installation groove 10 through the guide rod 902 on its outer side. When the connector of the external data cable is connected to the vehicle-mounted charger through the USB interface 11, the two fixing frames 903 are moved back by the spring 904 on one side of the guide rod 902 and achieve sealed and fitting fixation, achieving the function of dust prevention and reducing the risk of damage to the vehicle-mounted charger; when no data cable is carried, the end 7 on one side of the vehicle-mounted charger can also be used. Since the spiral connecting wire 6 connected to the end 7 and the charger 3 is stretchable, it can meet the needs of users in different positions. After use, the end 7 can be placed in the accommodation groove 803 inside the fixing seat 801. Since a magnetic attachment is provided on one side of the accommodation groove 803, the end 7 can be magnetically fixed during placement, keeping the vehicle interior environment clean and preventing the situation where the data cable is damaged by being stepped on underfoot.
[0034] The embodiments of the present utility model are given for the purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles of the present utility model and its practical applications, and to enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.
