[0023] See also Figure 1 , Figure 1It is a structural schematic diagram of an embodiment of a test device 10 provided in the present application. The test device 10 of this embodiment includes a test bench 11, a head-up display device 12, a constant temperature device 13 and a test mechanism 14.

[0024] Please also read Figure 1 and Figure 2 , Figure 2 yes Figure 1 A schematic structural diagram of a middle box 111 , the test bench 11 comprises a box 111 and a windshield 112 , and the windshield 112 is installed on the box 111 to form a closed space 101 .

[0025] Specifically, the box body 111 includes a bottom wall 1111 and a peripheral side wall 1112 . The peripheral side wall 1112 is connected to the bottom wall 1111 to form a receiving space 102 and an opening 103 communicating with the receiving space 102 . The windshield 112 covers the opening 103 to form the above-mentioned enclosed space 101 .

[0026] The windshield 112 is used to receive the test light S1 . In this embodiment, the test light S1 is sunlight.

[0027] Further reading Figure 1 The head-up display device 12 is disposed in the enclosed space 101 , and the constant temperature device 13 is used to maintain the temperature in the enclosed space 101 at a constant temperature.

[0028] The thermostat 13 includes a thermostat 131 , a first temperature detector 132 and a heater 133 . The first temperature detector 132 and the heater 133 are respectively disposed in the enclosed space 101 . The thermostat 131 is electrically connected to the first temperature detector 132 and the heater 133 .

[0029] Specifically, during the test, the first temperature detector 132 detects the temperature in the enclosed space 101 to determine whether the temperature in the enclosed space 101 is a preset temperature. When the temperature in the enclosed space 101 is lower than the preset temperature, the thermostat 131 remains open, so that the heater 133 generates heat, thereby increasing the temperature in the enclosed space 101. When the temperature in the enclosed space 101 is higher than the preset temperature, the thermostat 131 remains closed, so that the heater 133 no longer generates heat, thereby decreasing the temperature in the enclosed space 101. In this way, the temperature in the enclosed space 101 is maintained at a constant temperature.

[0030] It can be understood that the above-mentioned constant temperature, that is, the preset temperature can be set according to actual needs, and the type of heater 133 can also be selected according to actual needs, such as selecting a resistance wire, which is not limited.

[0031] Optionally, the heater 133 is attached to the inner wall of the box body 111 on one side close to the enclosed space 101 .

[0032] Optionally, there are multiple heaters 133, and the multiple heaters 133 are respectively attached to the inner walls on different sides of the box 111. For example, in this embodiment, there are two heaters 133, and the two heaters 133 are respectively attached to the inner walls on two opposite sides of the box 111.

[0033] The testing mechanism 14 is electrically connected to the head-up display device 12 to obtain temperature information of the head-up display device 12, thereby completing a sunlight backflow test on the head-up display device 12. Through this arrangement, on the one hand, the head-up display device 12 is first subjected to a sunlight backflow test before daily use to ensure that the performance of the head-up display device 12 in terms of sunlight backflow meets the use requirements. On the other hand, by testing the head-up display device 12 in a closed and constant temperature environment, errors in the test results caused by different ambient temperatures are avoided, thereby improving the accuracy of the test results.

[0034] The testing mechanism 14 includes a second temperature detector 141 and a data collector 142 . The second temperature detector 141 is used to detect the temperature of the head-up display device 12 and generate a detection signal. The data collector 142 is electrically connected to the second temperature detector 141 to generate temperature data according to the detection signal.

[0035] Furthermore, the testing device 10 in this embodiment further includes a power supply 15 , and the power supply 15 is electrically connected to the thermostat 131 and the heater 133 , respectively.

[0036] Specifically, in actual application, when the thermostat 131 as mentioned above is kept open, the power supply 15 supplies power to the heater 133, so that the heater 133 generates heat. When the thermostat 131 as mentioned above is kept closed, the power supply 15 no longer supplies power to the heater 133, so that the heater 133 no longer generates heat.

[0037] Furthermore, the testing device 10 in this embodiment further includes an adjustment platform 16 , on which the head-up display device 12 is disposed, and the adjustment platform 16 is used to adjust the angle of the head-up display device 12 relative to the test light S1 .

[0038] Furthermore, the testing device 10 in this embodiment further includes a host computer 17 , which is electrically connected to the adjustment platform 16 to determine the angle of the head-up display device 12 relative to the sunlight according to the current time.

[0039] Specifically, in actual applications, sunlight will shift with the change of time. Therefore, in order to ensure that the performance of the head-up display device 12 in this embodiment meets the use requirements at different times in terms of sunlight backflow, the current time is obtained by the host computer 17 in this embodiment, and the offset angle of the sunlight is determined according to the current time, thereby determining the angle of the head-up display device 12 relative to the sunlight, and then controlling the adjustment platform 16 to adjust the head-up display device 12.

[0040] The host computer 17 in this embodiment is also electrically connected to the data collector 142 to obtain a plurality of temperature data and obtain temperature change information of the head-up display device 12 according to the plurality of temperature data.

[0041] See also Figure 3 , Figure 3 It is a structural diagram of another embodiment of the test device 20 provided in the present application. The test device 20 in this embodiment also includes a light source 21. Other structures of the test device 20 in this embodiment are the same as the test device 10 in the above embodiment, and will not be repeated here.

[0042] The light source 21 is disposed on a side of the windshield 112 away from the enclosed space 101 , and the light source 12 is used to emit a test light S2 toward the windshield 112 .

[0043] It can be understood that in this embodiment, the light source 21 is a light source that simulates the sun, and the test light S2 emitted by the light source 21 is a light that simulates sunlight. In practical applications, the type of light source 21 can be selected according to actual needs, such as selecting a halogen lamp, and there is no limitation on this.
