DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figures 1 to 5 The dimmable and color-changing side window electric heated glass comprises an electric heated glass 1 and a thermostat 2. The electric heated glass 1 comprises an ITO glass 11, an inner glass 12, an electrochromic film 14 and an anti-splash layer 15. The inner surfaces of the ITO glass 11 and the inner surfaces of the inner glass 12 are both adhered with PVB films 13, and the ITO glass 11 and the inner glass 12 are respectively assembled on both sides of the electrochromic film 14 through the PVB films 13. A thermistor is assembled between the ITO glass 11 and the inner glass 12. A wire outlet hole 3 is opened on the surface side of the inner glass 12. The ITO glass 11 is connected to two electric heating leads 6, the thermistor is connected to two thermistor leads 7 and two spare thermistor leads 8, the electrochromic film 14 is connected to two electrochromic film leads 9, and the electric heating leads 6 and the thermistor leads 7 are connected to the thermostat 2 after passing through the wire outlet hole 3, and the thermostat 2 and the electrochromic film leads 9 are both connected to an external power supply.

[0022] The ITO glass 11 and the inner glass 12 are both tempered, and the two are assembled using a sandwich lamination process.

[0023] The ITO glass 11 generates heat when electricity is applied.

[0024] The thermistor is arranged in the heating area of ​​the ITO glass 11, and there are two thermistors in total. Each thermistor is connected to a thermistor lead 7 and a spare thermistor lead 8. The thermistor lead 7 is connected to the thermostat 2. When the glass temperature is lower than the set temperature value, the electric heating system starts, and the thermistor changes its resistance as the glass temperature rises. When the temperature reaches the set maximum temperature, the electric heating system is turned off, so as to realize the controllability of the electric heating of the side window glass, realize the defogging and defrosting performance, and bring better vision to passengers.

[0025] The spare thermistor lead 8 is usually not connected to the thermostat 2. When the thermistor lead 7 has a problem, the thermistor lead 7 can be disconnected from the thermostat 2 and the spare thermistor lead 8 can be connected to the thermostat 2 to achieve fast and effective maintenance.

[0026] The electrochromic film 14 can realize the function of stepless color change. When the power is not turned on, the transmittance of the side window glass is the lowest and is in a dark state. When the AC voltage is turned on, as the voltage changes according to a sine curve, the transmittance of the side window glass gradually increases, and gradually changes from a dark state to a bright state. When the voltage reaches the maximum value, the transmittance of the side window glass also reaches the maximum value and is the brightest state.

[0027] According to the different needs of passengers for light intensity, the transmittance of the side window glass can be intelligently adjusted to achieve the dimming and color-changing functions of the side window glass.

[0028] The anti-splash layer 15 is used to enhance the impact resistance and anti-splash performance of the side window glass, increase its safety, and ensure the safety of the people in the vehicle.

[0029] Specifically, the ITO glass 11 includes an outer sheet of glass and an ITO conductive film, and the ITO conductive film is mounted on the surface of the outer sheet of glass.

[0030] ITO conductive film is a transparent conductive film of tin oxide. ITO glass 11 is a high-tech product obtained by sputtering an indium tin oxide conductive film coating on glass using planar magnetron technology in a highly purified factory environment and then undergoing high-temperature annealing treatment.

[0031] The ITO conductive film generates heat when electricity is supplied, thereby realizing the heating function of the ITO glass 11, and further realizing the defogging and defrosting performance.

[0032] Specifically, if Figure 1 , Figure 4 and Figure 5 As shown, there are two wire outlet holes 3, and hole plugs 4 are installed in the wire outlet holes 3. The side surface of the hole plug 4 is provided with a lead groove 5. The electric heating lead 6, thermistor lead 7 and the spare thermistor lead 8 pass through the lead groove 5 of the hole plug 4 in one wire outlet hole 3, and the electrochromic film lead 9 passes through the lead groove 5 of the hole plug 4 in the other wire outlet hole 3.

[0033] Specifically, if Figure 5 As shown, the hole plug 4 is made of rubber material, and is composed of a cylindrical structure at the front end and a truncated cone structure at the rear end. The cylindrical structure and the outlet hole 3 are in an interference fit relationship.

[0034] The rubber material of the hole plug 4 makes it have good elasticity, and it can be installed in the outlet hole 3 to ensure that the lead wire passes through, while the outlet hole 3 is well sealed, thereby increasing the safety of the side window glass.

[0035] The number of the lead wire slots 5 on the hole plug 4 is determined according to the number of lead wires passing through the corresponding outlet hole 3. In this embodiment, six and two lead wire slots are respectively formed on the two hole plugs 4.

[0036] Specifically, the anti-splash layer 15 includes an anti-splash film and a film, and the anti-splash film is assembled on the surface of the film, and the film is adhered to the outer surface of the inner glass 12.

[0037] Specifically, if Figure 3 As shown, edge sealant 16 is installed on the edge between the ITO glass 11 and the inner glass 12 .

[0038] The edge sealant 16 increases the sealing performance of the side window glass, and can enhance the strength and impact resistance of the side window glass.

[0039] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present invention. As long as these changes do not deviate from the concept of the present invention, they all belong to the protection scope of the present invention.
