[0058] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0059] In the relevant technology, there are only methods and test standards for vibration testing of other automobile parts. However, as a product of the new era, there are no experimental methods and experimental standards for vibration testing of photovoltaic roofs. Therefore, it is impossible to conduct vibration tests on photovoltaic roofs before use, which makes photovoltaic roofs have certain safety hazards during normal use by users.

[0060] The photovoltaic roof vibration test method and device provided in the embodiment of the present application can be applied to the application environment of the photovoltaic roof vibration test system, and the photovoltaic roof vibration test system includes a test bench and a vibration fixture with vibration test functions and electrical performance test functions. By placing the photovoltaic roof to be tested on the vibration fixture, the vibration of the test bench drives the photovoltaic roof to be tested on the vibration fixture to vibrate, so as to realize the vibration test of the photovoltaic roof to be tested. Optionally, the test bench can also have a data storage function, and can pre-set parameters such as preset loading standard parameters, preset vibration parameters, test qualified conditions, etc., so that in the vibration test, the photovoltaic roof to be tested can be subjected to a vibration test according to parameters such as loading standard parameters, preset vibration parameters, test qualified conditions, etc.

[0061] In an exemplary embodiment, as shown in FIG1 , a vibration test method for a photovoltaic roof is provided, which is described by taking the method applied to a test bench as an example, and includes the following steps 101 to 104. Among them:

[0062] Step 101, fix the photovoltaic roof to be tested on the profile of the vibration tooling according to the preset loading standard parameters; wherein the profile meets the actual loading edge conditions of the photovoltaic roof, so that the photovoltaic roof to be tested is in a simulated loading state.

[0063] The preset standard parameters for installation can be understood as the standard parameters for installing the photovoltaic roof on a car. In addition, when the photovoltaic roof is actually installed at the preset position of the car, the edge of the preset position needs to meet the corresponding actual installation edge conditions, so that the photovoltaic roof can be installed in a suitable manner with the car, and the photovoltaic roof can be used normally during normal driving of the car. Therefore, installing the photovoltaic roof on the car according to the parameters can make the photovoltaic roof to be tested be in a simulated installation state.

[0065] Among them, the preset vibration parameters are the parameters input to the test bench, and the test bench simulates vibration according to the preset vibration parameters to realize the vibration test of the photovoltaic roof to be tested. When the test bench simulates vibration, the vibration tooling vibrates with the vibration of the test bench, and the vibration of the vibration tooling causes the internal support column to shake, thereby driving the photovoltaic roof to be tested set on the molded surface to vibrate. After the entire vibration process is completed, the vibration test of the photovoltaic roof to be tested is completed, and the vibration result data is obtained after the vibration test is completed. In addition, the vibration result data represents the test data of the photovoltaic roof to be tested completing the vibration test.

[0066] Optionally, preset vibration parameters are input into the test bench so that the test bench simulates vibration according to the preset vibration parameters, and then the support columns of the vibration tooling are controlled to drive the photovoltaic roof to be tested to perform a vibration test.

The preset vibration parameters are input into the test bench, so that the test bench simulates vibration according to the preset vibration parameters, and then the support column of the vibration tooling is controlled to drive the photovoltaic roof to be tested to perform a vibration test, and the vibration test results are obtained after the photovoltaic roof to be tested completes the vibration test, and the vibration result data is obtained. When the photovoltaic roof to be tested completes the vibration test, the electrical performance test of the photovoltaic roof to be tested is performed, and after the photovoltaic roof to be tested completes the electrical performance test, the test data of the photovoltaic roof to be tested is obtained to obtain the performance result data. The vibration result data and the performance result data are respectively compared with the corresponding test qualified conditions, and whether the photovoltaic roof to be tested is qualified is judged according to the comparison results of the vibration result data and the comparison results of the performance result data.
