[0027] In order to make the purpose, technical scheme and advantage of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment.

[0028] As Figs. 1-3 Indicated, in an embodiment, an electrochromic rearview mirror test tool, comprising: test substrate 1, and test substrate 1 below is rotationally connected with placing base 3 through swing plate 2. Wherein, placing base 3 both sides are symmetrically provided with support plate 31, and support plate 31 is rotationally connected with swing plate 2.

[0029] Specifically, the rotation angle of swing plate 2 is 0-30 °. In the vehicle driving scene, when the driver observes the rear environment through the rearview mirror, the natural activity range of the head and eye is usually small, and the view angle change is concentrated in the range of 0-30 °. This angle has covered the typical line of sight offset observed through the rearview mirror during driving, ensuring that the test result is consistent with the actual use scene. The color change of electrochromic material is sensitive to the incident light angle, but within the range of 0-30 °, the light reflectivity and color difference are most significant (such as glare suppression effect, color uniformity, etc.). When more than 30 °, due to the mirror reflection law (such as Fresnel effect), the light incidence angle tends to be critical, which may cause the color change effect to tend to saturation or the change amplitude to decrease, and the test value is limited. And lens manufacturing defects (such as uneven coating, conductive layer fracture) are more likely to be exposed under the 0-30 ° view angle. For example, a small scratch or uneven color change may be amplified within this range due to light reflection differences, but at a larger angle, it may be difficult to detect due to light scattering. The rotation range of 0-30 ° can simplify the mechanical complexity of the swing plate and support structure, reduce manufacturing costs and failure rate. Test personnel do not need to frequently adjust the large angle during operation, which meets the ergonomic requirements, reduces fatigue and improves test consistency.

[0030] It can be understood that the test substrate 1 can be rotated on the placing base 3 through the swing plate 2, so as to adjust different test angles, and facilitate the test worker to confirm and observe the color-changing appearance effect from different angles. In actual product testing, since the color-changing appearance effect of the lens at different angles will be different, the rotatable test substrate 1 can meet the needs of comprehensive detection, and avoid the problem of missed detection of abnormal products.

[0031] Please continue to refer to Figs. 1-2 In the embodiment, the test substrate 1 is provided with a profiling fixing block 4, one side of the profiling fixing block 4 is provided with a conducting block 5, and the bottom of the profiling fixing block 4 and the conducting block 5 is correspondingly provided with a magnetic attraction layer. A plurality of profiling fixing blocks 4 can be used to fix the product to be tested.

[0032] Specifically, the test substrate 1 is made of metal material, and the magnetic attraction layer is made of strong magnetic material. The adsorption force between the metal material and the strong magnetic material can ensure that the profiling fixing block 4 and the conducting block 5 are firmly fixed on the test substrate 1. The conducting block 5 includes a positive electrode conducting block 51 and a negative electrode conducting block 52. The positive and negative test positions of the corresponding conducting sheet on different lenses can be adapted by moving the conducting block 5. In addition, the profiling fixing block 4 is provided with a profiling groove 41 on the upper end face, and the depth of the profiling groove 41 is greater than or equal to the thickness of the lens, which can well fit the shape of the product to be tested, and effectively fix the lens.

[0033] It can be understood that in the actual production process, the product shape and the conducting sheet have different size specifications. Therefore, in the testing process, the profiling fixing block 4 can be moved to fix the product to be tested with different sizes, and the conducting block 5 can be moved to the test position of the corresponding conducting sheet on the product to be tested.

[0034] Further, one side of the test substrate 1 is provided with a detection box 6, the detection box 6 is provided with a display screen 7 above, and the middle part of the placing base 3 is correspondingly provided with a test switch 9, and the test switch 9 is electrically connected with the detection box 6. In addition, the test substrate 1 is provided with a wiring hole 11 for passing through the wire 8, so that the conducting block 5 can be electrically connected with the detection box 6, the display screen 7 and the test switch 9 below through the wire 8.

[0035] Exemplarily, the test switch 9 can select a three-grade knob switch, which internally connects different circuit paths through contact switching: color-changing grade: connecting positive voltage output end; discoloring grade: connecting reverse voltage output end or short-circuit contact; power-off grade: disconnecting all contacts.

[0036] 1) When the test switch 9 is switched to the "color changing" gear, the detection box 6 applies a forward direct current voltage to the conductive layer of the electrochromic lens through the positive conductive block 51 and the negative conductive block 52 of the conducting block 5. Under the driving of the forward voltage, the electrochromic material undergoes an oxidation-reduction reaction inside, ions migrate from the electrolyte layer to the electrochromic layer, causing the material optical band gap to change, the lens color gradually deepens, and the display screen 7 displays the current value and voltage value in real time, ensuring the stability of the circuit (such as stable current and constant voltage).

[0037] 2) When the test switch 9 is switched to the "color fading" gear, the detection box 6 outputs a reverse voltage or a short circuit (zero voltage), and the reverse voltage forces the ions to return to the electrolyte layer, and the electrochromic layer restores the initial optical state. The display screen 7 monitors the voltage polarity switching and the resistance change (such as resistance from low to high) during the color fading process.

[0038] 3) When the test switch 9 is switched to the "power off" gear, the detection box 6 cuts off the power output, and there is no current passing between the conducting block 5 and the lens conductive layer.

[0039] It can be understood that during the test process, the color changing, color fading and power off can be arbitrarily adjusted by adjusting the gear of the test switch 9, and the test results (current value, voltage value and resistance value, etc.) can be displayed in real time through the display screen 7.

[0040] Working principle: Take the product (lens) to be tested, move the profiling fixing block 4 to fix the product to be tested, and then move the conducting block 5 to the predetermined test position; after connecting the test circuit, adjust the test switch 9 to different gears, rotate the test base plate 1 to observe the color changing state, and read the test data through the display screen 7.

[0041] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
