[0006] Further, the side wall, top wall and bottom wall of the box body except the opening are non-light-transmitting entities.

[0007] Further, the image presenter is a photo holder with adjustable angle towards the opening.

[0008] Further, the image presenter is a display screen with adjustable angle towards the opening, and the display screen and the illumination row lamp are connected to the master control switch and are driven to light up or turn off.

[0009] Further, the master control switch is provided with a dimmer knob for adjusting the output of the illumination row lamp.

[0010] The utility model discloses a carrier, have technical effect and progressivity: utilize detachable assembly's glass carrier to carry out partition film, and with the box body convenient assembly participates in testing, has saved the dosage of the window film of to be measured, and the image brightness for testing is adjustable, is favorable to obtain the light transmission effect of window film under different driving environment working condition, has improved the comprehensiveness of test result. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 It is the carrier structure schematic diagram for window film definition of the utility model. DETAILED DESCRIPTION

[0012] The following will be combined embodiment drawing, the specific implementation of the utility model is further detailed, so that the technical scheme of the utility model is more easy to understand, grasps, and thus makes the protection scope of the utility model more clear definition.

[0013] The utility model discloses a kind of carriers for window film definition test, corresponding image environmental illumination intensity can be autonomously adjusted, so as to satisfy the light transmission performance and definition test of window film product under different driving scenarios.

[0014] The carrier for window film definition test of the utility model, from the structure composition of overview, it mainly includes two parts of the box body 1 with single-side opening and glass carrier 2. Wherein the inner cavity of box body 1 is equipped with the image presenter 3 of recording driving visual field scene, and the image presenter 3 is towards the opening of box body;The bottom of box body 1 is equipped with the illumination row lamp 4 towards image presenter 3, for adjusting the ambient brightness of image presenter;Box body 1 is equipped with the positioning groove 11 suitable for glass carrier 2 plug-in and fall into in opening, the positioning groove is towards box body top opening setting, and both sides and bottom edge are all sunken groove. Here, the glass carrier is based on the flexible plug-in setting of positioning groove, namely can be extracted to facilitate the film tearing and pasting operation, and back insertion is tested in positioning groove. For the convenience of visual comparison, usually the glass carrier is attached with two or more than two window films to be measured, or one is standard reference sample or contrast sample.

[0015] It should be noted that the actual process of window film definition test is obtained by manual visual detection or image analysis by means of other tools. These are not the technical problems to be solved by the present application, so they are not described. The carrier of the present application is only used as the carrier and observation object of the window film during such testing to increase the flexibility of testing. In order to reduce the influence of external light on the image presenter in the laboratory, the side wall, top wall and bottom wall of the box body 1 except the opening are non-transparent entities, preferably black or frosted gray injection molded bodies, etc.

[0016] In the preferred embodiment, the image presenter is a display screen, and the display screen and the lighting array are both connected to the master switch and driven to be turned on or off. Here, the display screen is adjusted to be adjustable towards the open angle based on the ball head support behind it, etc., to approach the simulation of the inclination state of different vehicle front windshield glasses. The master switch is provided with a dimmer knob 6 for output light adjustment of the lighting array. The display screen mainly presents a composite image simulating the road and the surrounding scene of the driving scene; if necessary, it can also display the rear scene image of the vehicle under the simulation of the rearview mirror view angle, so as to realize one film multiple measurement. Here, the dimmer knob itself has a switch that is turned on and off by a switching circuit, and it can adjust the current flowing through the lighting array by rotating, that is, it can realize step or stepless light adjustment, and obtain images presented in different weather and day and night conditions such as sunny, cloudy, cloudy, rainy, night, etc. Of course, the output brightness of the display screen itself does not change during adjustment. In addition to the dimmer knob, the master switch can also be designed as an integrated gear switch, a slide switch or a split design key switch, etc., without limitation on the specific implementation of the carrier.

[0017] In addition to the preferred embodiment, the image presenter can also be designed as a photo holder with an adjustable angle towards the opening. In the state that the glass slide is not inserted, the staff can replace the photos through the open opening, so that the circuit design is optimized to make the dimmer knob only associated with the lighting array.

[0018] As can be seen from the above description of the scheme and embodiment of the carrier of the utility model, it has substantial characteristics and progress: the glass slide is detachably assembled for partitioning and film pasting, and is conveniently assembled with the box body for testing, which saves the amount of window film to be tested, and the image brightness for testing is adjustable, which is conducive to obtaining the light transmission effect of the window film under different driving environmental conditions and improving the comprehensiveness of the test results.

[0019] In addition to the above embodiments, the utility model can also have other implementation manners, and any technical scheme formed by equivalent replacement or equivalent transformation falls within the scope of the utility model claimed.
