[0038] In this embodiment, the base 10 is a rectangular block-shaped plastic part.

[0039] The working principle and beneficial effects of this utility model are as follows:

[0040] This utility model discloses a magnetic charging port for a car seat tablet bracket, which is installed on the back of a car seat to solve the charging needs of rear passengers. The car seat has a seat-end interface that serves as the input end of the magnetic charging port. The magnetic charging port outputs to a charging device, which can currently be a tablet bracket. The magnetic block 13 can magnetically fix the charging interface of the tablet bracket, improving the stability of the connection between the two. The charging module is composed of a fast charging module, and a Type-C connector is led out from the charging module. The charging module can lead out 7-8 pins to the tablet bracket, which can be plugged into the Type-C interface on the tablet for charging. The tablet is directly connected to the car's host via WIFI to realize the function of controlling in-vehicle equipment (air conditioning, windows, sunroof, etc.), which is convenient for rear passengers and improves the overall driving and riding experience of the car.

[0056] 2-pin with charging function;

[0057] 6-pin connector with charging and data transfer functions;

[0058] 7-pin connector with charging and Wi-Fi connectivity.

[0059] Example 2

[0060] The similarities between Example 2 and Example 1 will not be repeated here, such as... Figure 14 , 15 As shown, the difference is that in this embodiment, the back of the base 10 is provided with a bottom groove 20 near the edge. The inner wall of the bottom groove 20 is set in a constricted manner towards the bottom end of the groove. The sealing strip 15 is stuck at the groove opening end of the bottom groove 20. The bottom groove 20 is filled with a plurality of water-absorbing and expanding rubber blocks 16. The rubber blocks 16 are spherical and abut against the inner wall of the bottom groove 20. The side liquid inlet 17 is opened at the side end of the base 10 and communicates with the bottom groove 20.

[0061] In this embodiment, the side liquid inlet 17 is set in an open shape away from the bottom groove 20. Multiple heat dissipation metal strips 18 are embedded in the base 10, with both ends of the heat dissipation metal strips 18 extending into the side liquid inlet 17. Multiple sets of heat dissipation metal sheets 19 are vertically embedded on the back of the base 10, with the bottom end of the heat dissipation metal sheet 19 flush with the back of the base 10 and the top end of the heat dissipation metal sheet 19 connected to the heat dissipation metal strips 18.

[0062] The working principle and beneficial effects of this utility model are as follows:

[0063] This utility model discloses a magnetic charging port for a car seat flat bracket, which has waterproof and heat dissipation performance. A heat dissipation metal sheet 19 is embedded on the back of the base 10 that is in contact with the PCB board 11. After the heat dissipation metal sheet 19 absorbs heat, it is transferred to the outside of the side liquid inlet 17 through the heat dissipation metal strip 18, thereby improving the heat dissipation effect. When the surface of the charging port is immersed in water, the liquid droplets are guided into the bottom groove 20 along the heat dissipation metal strip 18 at the side liquid inlet 17. The rubber block 16 absorbs water and expands, and abuts against the inner wall of the bottom groove 20. Because the inner wall of the bottom groove 20 is set in a constricted shape towards its bottom end, it is difficult for the rubber block 16 to move towards the bottom end of the bottom groove 20. It can only move towards the opening end of the bottom groove 20 and abut against the sealing strip 15 located at the opening end of the bottom groove 20, thereby pressing the sealing strip 15 and preventing the end of the PCB board 11 that is in contact with the base 10 from being immersed in water.

[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
