In order to ensure good safety for the driver during driving, a heating film is usually installed for the car rearview mirror, so that the heating film is heated and the heat generated is transferred to the car rearview mirror lens closely attached to it, so that the water droplets or fog on the car rearview mirror lens evaporate and dissipate. The heating film is more closely attached to the car rearview mirror lens and evenly transfers heat to the car rearview mirror lens. The heating film is adhered to the car rearview mirror lens through the backing adhesive. Therefore, during the long-term heating operation of the heating film, the adhesive between the heating film and the rearview mirror lens is easily changed by heat. When the heating film needs to be repaired and replaced later, it is inconvenient for the operator to remove the heating film from the car rearview mirror lens, and the adhesive attached to the car rearview mirror lens is not easy to clean.

[0023] A heating film for a rearview mirror of an automobile comprises a first polyester resin sheet 1, a heating resistance wire 2 and a second polyester resin sheet 3. The heating resistance wire 2 is fixedly connected to the outer side of the first polyester resin sheet 1, the second polyester resin sheet 3 is fixedly connected to the other side of the heating resistance wire 2, a terminal 4 is fixedly connected to the end of the heating resistance wire 2, a hole 5 is provided on the inner side of the first polyester resin sheet 1, a clamping column 6 is slidably connected to the inner side of the hole 5, a lens 7 is fixedly connected to the end of one side of the clamping column 6, an adhesive ring 8 is fixedly connected to the other end of the clamping column 6, a pin 9 is slidably connected to the inner side of the adhesive ring 8, an elastic clamp 10 is fixedly connected to the outer side of the pin 9, an end of the pin 9 away from the lens 7 is fixedly connected to a mirror support 11, and a clamping groove 12 is provided on the inner side of the clamping column 6.

[0024] The first polyester resin sheet 1 and the second polyester resin sheet 3 are both provided with holes 5 of the same size. The holes 5 on the inner side of the first polyester resin sheet 1 and the holes 5 on the inner side of the second polyester resin sheet 3 are on the same vertical line. The holes 5 on the inner sides of the first polyester resin sheet 1 and the second polyester resin sheet 3 are offset from the heating resistor 2, so that the heating film of the rearview mirror of the automobile is fixed and restricted on the lens 7. The end of the adhesive ring 8 away from the lens 7 is adhesively connected to the mirror holder 11. The adhesive ring 8 has elastic deformation. The adhesive ring 8 is arranged in the hole 5 provided in the first polyester resin sheet 1. The inner diameter of the adhesive ring 8 is the same as the inner diameter of the clamping column 6, which can enhance the connection relationship between the lens 7 and the mirror holder 11. The inner diameter of the elastic clamp 10 is the same as the inner diameter of the pin 9. The diameters are the same, and the maximum outer diameter of the elastic clamp ring 10 is much larger than the diameter of the pin 9. The elastic clamp ring 10 is engaged in the groove 12, and the outer side of the elastic clamp ring 10 is an arc-shaped surface, which can fix and limit the heating film of the automobile rearview mirror between the lens 7 and the mirror holder 11; there are several engaging columns 6, and the engaging columns 6 are evenly distributed on the side of the lens 7 close to the mirror holder 11. The position of the engaging columns 6 and the laying position of the heating resistor wire 2 are mutually offset, which is convenient for the engaging columns 6 to be inserted into the inner side of the heating film of the automobile rearview mirror; the pin 9 slides on the inner side of the engaging columns 6, and the length of the pin 9 is less than or equal to the length of the engaging columns 6 plus the thickness of the adhesive ring 8, which can ensure the stability of the automobile rearview mirror heating film fixed between the lens 7 and the mirror holder 11.

[0025] Working process: when using the automobile rearview mirror heating film and applying the automobile rearview mirror heating film to the automobile rearview mirror, the lens 7 is laid flat on a horizontal plane, and the engaging column 6 fixedly connected to the outside of the lens 7 is oriented above the horizontal plane, and then the heating film corresponding to the distribution position of the engaging column 6 on the outside of the lens 7 is sleeved on the outside of the engaging column 6 according to the contour of the lens 7. Since the heating film is composed of a first polyester resin sheet 1, a heating resistor wire 2 and a second polyester resin sheet 3, the engaging column 6 can be passed through the heating film through the hole 5 coaxial with the first polyester resin sheet 1 and the second polyester resin sheet 3. After the heating film is sleeved on the outside of the engaging column 6 and tightly attached to one side of the lens 7, the mirror holder 11 can be sleeved on the outside of the lens 7. At this time, the pin 9 fixedly connected to the outside of the mirror holder 11 can be correspondingly inserted into the inside of the engaging column 6. In the process of the pin 9 sliding in the engaging column 6, the elastic clamp 10 fixedly connected to the outside of the pin 9 is restricted by the inner diameter opening of the engaging column 6 and produces elastic deformation, so that the elastic clamp 10 can The elastic clamping ring 10 can be restored by sliding on the inner side of the locking column 6 until the elastic clamping ring 10 slides to the position of the locking groove 12 opened on the inner side of the locking column 6, and the elastic clamping ring 10 can be locked in the locking groove 12 to restrict the pin 9 more stably on the inner side of the locking column 6. During the process of the elastic clamping ring 10 being locked in the locking groove 12, the only adhesive side of the adhesive ring 8 can be adhered to the mirror holder 11. In this way, when the lens 7 and the mirror holder 11 are connected together, the lens 7 and the mirror holder 11 fix and restrict the heating film between them, so as to ensure the good working effect of the heating film on the rearview mirror lens 7 of the automobile. In addition, the rearview mirror heating film of the automobile eliminates the relationship between the heating film and the rearview mirror lens 7 through the adhesive bonding, so that when the heating film needs to be repaired and replaced later, it is convenient for the operator to remove the heating film from the rearview mirror lens 7 of the automobile, avoiding the cumbersome process of cleaning the large piece of adhesive attached to the rearview mirror lens 7 of the automobile.
