Description

Technical Field

[0001] The utility model belongs to the technical field of dimming films, and in particular relates to a car defogging dimming film. Background Art

[0002] Existing dimming films are mostly composed of two layers of flexible transparent conductive films (ITO films) and a layer of polymer dispersed liquid crystal material (PDLC). The liquid crystal translucent film is controlled by an external electric field to switch between colorless, transparent and opaque. When the automotive dimming film is in use, the temperature difference between the inside and outside of the car changes, causing the windows to fog. This means that even if the dimming film is switched to the translucent mode, the windows still have poor light transmittance due to condensation of water vapor. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of the utility model is to provide a car defogger dimming film, which can achieve self-heating and then can demist the water mist on the surface of the dimming film by heating. At the same time, an insulating soft film is connected between the controller that controls the heating wire and the dimming film to facilitate large-scale folding and then easy installation.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A car defog dimming film comprises a dimming composite film and a controller, wherein the dimming composite film is sequentially stacked with a PET protective film, a self-adhesive surface, a thermal conductive layer, an ITO film, a liquid crystal molecule layer, an ITO film, and a PET protective film, a thermal conductive wire is evenly laid on the surface of the thermal conductive layer, the controller is placed on one side of the dimming composite film, a side of the thermal conductive layer close to the controller is connected to an insulating soft film, an end of the insulating soft film facing away from the thermal conductive layer is provided with a circuit connection board, the thermal conductive wire penetrates the insulating soft film, the thermal conductive wire is connected to the circuit connection board, and the circuit connection board is placed on the inner side of the controller.

[0006] Furthermore, the controller includes an upper shell and a lower shell, and the circuit connection board is placed between the upper shell and the lower shell.

[0007] Furthermore, one end of the circuit connection board is provided with a control wire connected thereto, and the control wire passes through the end surface of the controller.

[0008] Furthermore, a clamping head is provided at the bottom of the upper shell, and a clamping slot is provided on the surface of the lower shell, and the clamping head is adapted to the inner size of the clamping slot.

[0009] Furthermore, the thermal conductive wire is nanoscale.

[0010] Compared with the prior art, the utility model has the following beneficial effects: during installation, the dimming film is attached to the inner wall of the window glass, and the controller is placed on one side of the window. Since an insulating soft film is connected between the dimming film and the controller, the two can be folded to a large extent for easy installation. When the surface of the dimming film is misted, the heat conducting wire can be energized for heating to increase the temperature of the dimming film, thereby evaporating the water mist and ensuring its light transmittance.

DETAILED DESCRIPTION

[0016] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0017] Please refer to Figure 1 and Figure 2As shown, a car defogger dimming film comprises a dimming composite film 1 and a controller 2. The dimming composite film 1 is sequentially stacked with a PET protective film 101, a self-adhesive surface 102, a heat-conducting layer 103, an ITO film 104, a liquid crystal molecule layer 105, an ITO film 104, and a PET protective film 101. A heat-conducting wire 1031 is evenly laid on the surface of the heat-conducting layer 103. The controller 2 is placed on one side of the dimming composite film 1. The side of the heat-conducting layer 103 close to the controller 2 is connected with an insulating soft film 107 so that The connection strength between the controller 2 and the dimming combination film 1 can be obtained, and the film can be folded greatly to facilitate installation when the film is laid. A circuit connecting board 106 is provided at one end of the insulating soft film 107 away from the thermal conductive layer 103. The thermal wire 1031 penetrates the insulating soft film 107 so that multiple thermal wires 1031 are isolated from each other. The thermal wire 1031 is connected to the circuit connecting board 106, and the circuit connecting board 106 is placed on the inner side of the controller 2 to effectively control the circuit connecting board 106.

[0018] The heat conductive wire 1031 is nanometer-grade to ensure that it will not hinder external light when transmitting light.

[0019] Please refer to Figure 1 and Figure 3 As shown, the controller 2 includes an upper shell 201 and a lower shell 202, and a circuit connection board 106 is placed between the upper shell 201 and the lower shell 202 to facilitate the connection between the dimming combination film 1 and the controller 2. A control wire 205 is connected to one end of the circuit connection board 106. The control wire 205 passes through the end surface of the controller 2, and the end of the control wire 205 is connected to the automobile control system to facilitate internal control.

[0020] A clamping head 203 is provided at the bottom of the upper shell 201, and a clamping slot 204 is provided on the surface of the lower shell 202. The inner dimensions of the clamping head 203 and the clamping slot 204 are adapted to each other, so that the upper shell 201 and the lower shell 202 can be disassembled for subsequent inspection and maintenance.

[0021] The working principle of the utility model is as follows: the circuit connection board 106 is clamped between the upper shell 201 and the lower shell 202, and the card slot 204 and the card head 203 cooperate with each other to ensure the overall stability of the controller 2. At this time, the circuit connection board 106 is effectively fixed inside the controller 2, the controller 2 is fixed on one side of the interior of the car, and the dimming combination film 1 is laid on the inner wall of the glass.

The light is then controlled and adjusted, and the multiple heat conductive wires 1031 are energized by energizing the circuit connection board 106, so that the dimming combination film 1 heats up to evaporate the water mist remaining on its surface, thereby realizing the demisting function.
