[0002] In cold or rainy weather, the car windows may be covered with frost or fog, affecting the transparency of the windows and the driver's field of vision. In order to meet the requirements of driving safety, the car windows only need to be heated to remove frost and fog, while maintaining the surface temperature of the window glass higher than the ambient temperature to effectively avoid re-icing or fogging.

[0003] The specification of Chinese invention patent CN202010616770.4 discloses "A kind of automobile side window heated glass". The patent embeds at least three metal wires in the thermoplastic interlayer, and the two ends of each metal wire are electrically connected to the first bus bar and the second bus bar respectively. Each metal wire extends between the upper edge and the second bus bar and passes through the first bus bar at least partially insulated.

[0004] The existing heated window glass and the above-mentioned side window heated glass both heat the window glass by energizing wires for heating. The heat diffusion efficiency generated by the energized wires is low, the defrosting and defogging effect on the window glass is insufficient, and the window field of view recovers slowly. At the same time, the wires need to be evenly laid in the window glass. Since the side windows of different car models use side window glasses of different shapes, it is difficult to lay the wires inside the glass, which is not conducive to the processing and production of the glass. Summary of the invention

[0016] As another improvement supplement of the present application, the bottom end of the air conditioning air duct is fixedly connected with an air inlet, and the air inlet is arranged in a semicircular shape. The semicircular air inlet only partially receives the hot air from the car air conditioner, effectively avoiding the use of the car air conditioner.

[0017] In summary, the present invention arranges the heating wire only in the middle of the side window glass through the busbar group, so as to heat the middle area of ​​the side window glass body, and then conducts lateral heat radiation through the metal wire corresponding to the cross of the heating wire, so as to quickly restore the middle field of view of the side window, which is convenient for the driver to check the rearview mirror through the field of view recovery area, and effectively improves the vehicle driving safety performance.

[0036] The second implementation method:

[0037] Compared with the first embodiment, this embodiment mainly adds a side window lining 4 and an air conditioning air duct 402. The specific newly added structures are as follows, and the remaining structures are consistent with the first embodiment.
