The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] In the related art, the existing fuel cell tilt test device generally uses a pull rod to support the test platform, which makes the tilt structure of the tilt test device unstable and the adjustable range of the tilt angle small, and it is impossible to conveniently implement multi-directional tilt testing. When the tilt test device performs a fuel cell tilt test, the tilt angle is determined by manual measurement with an angle meter or a level, and the measurement error is large. It is also impossible to adjust the tilt mechanism in place at one time, and multiple adjustments are required, which is time-consuming and labor-intensive. When the fuel cell is manually fixed, there may be problems such as offset and time-consuming and labor-intensive when the fuel cell is fixed. The present application proposes a fuel cell tilt test device, which can achieve the effect of automatic tilting of the tilt test device, precise and controllable tilt angle, and one-step adjustment without multiple adjustments. It can increase the adjustable range of the tilt angle. The tilt test device has a stable structure and the test process is time-saving and labor-saving, thereby improving test efficiency and test accuracy.

[0037] Reference below Figure 1-Figure 5 A tilt test device 2 for a fuel cell 1 according to an embodiment of the present invention is described.

[0039] It should be noted that the tilt test device for fuel cells in the prior art requires manual adjustment of the tilt mechanism when conducting the fuel cell tilt test, and the tilt mechanism needs to be adjusted multiple times to achieve the expected tilt angle. The tilt angle needs to be measured manually, the tilt angle measurement error is large, the tilt angle has a small adjustable range, the tilt structure is unstable, and offset may occur when fixing the fuel cell, which is time-consuming and labor-intensive, resulting in low test efficiency, low test accuracy, and poor test safety.

[0040] Based on this, the present application proposes a fuel cell 1 tilt test device 2, which is provided with a support frame 10, a first rotating platform 20, a second rotating platform 30, a driving mechanism 40, a tilt angle detection mechanism 50 and a controller 60.

[0041] like Figure 3As shown, the second rotating platform 30 is rotatably arranged on the first rotating platform 20 around the second horizontal axis, and the first horizontal axis and the second horizontal axis are perpendicular. Figure 1 When the middle direction is set, the extension direction of the second horizontal axis is Figure 1 In the Y direction, the first rotating platform 20 has two side walls spaced apart from each other along the Y direction, and the two side walls are provided with second assembly holes 23 positioned opposite to each other. The second rotating platform 30 is provided with a second boss structure 34 that cooperates with the second assembly hole 23. The second boss structure 34 on the second rotating platform 30 is assembled in the second assembly hole 23 to achieve a rotatable connection between the second rotating platform 30 and the first rotating platform 20. The second rotating platform 30 is used to fix the fuel cell 1. For example, a clamping mechanism can be provided on the second rotating platform 30 to fix the fuel cell 1, or a fixing frame can be provided on the second rotating platform 30 to fix the fuel cell 1.

[0042] The driving mechanism 40 is connected to the first rotating platform 20 and the second rotating platform 30 respectively. The driving mechanism 40 can drive the first rotating platform 20 to rotate around the first horizontal axis. The driving mechanism 40 can also drive the second rotating platform 30 to rotate around the second horizontal axis. The first rotating platform 20 and the second rotating platform 30 rotate to generate a tilt angle. The tilt angle detection mechanism 50 is used to detect the tilt angle of the first rotating platform 20 and the second rotating platform 30. The controller 60 can be a computer that can directly send instructions. The controller 60 is communicatively connected with the driving mechanism 40 and the tilt angle detection mechanism 50. The controller 60 can control the driving mechanism 40 to work. The controller 60 can receive detection information of the tilt angle detection mechanism 50. According to the detection information of the tilt angle detection mechanism 50, the controller 60 can control the driving mechanism 40 to stop working. The controller 60 can be arranged on the first plate 11.

[0043] Specifically, when it is necessary to drive the first rotating platform 20 to rotate around the first horizontal axis to the target tilt angle, the controller 60 controls the driving mechanism 40 to drive the first rotating platform 20 to rotate according to the tilt angle information of the first rotating platform 20 detected by the tilt angle detection mechanism 50, and when the tilt angle detection mechanism 50 detects that the tilt angle of the first rotating platform 20 reaches the expected value, the controller 60 controls the driving mechanism 40 to stop working. When it is necessary to drive the second rotating platform 30 to rotate around the second horizontal axis to the target tilt angle, the controller 60 controls the driving mechanism 40 to drive the second rotating platform 30 to rotate according to the tilt angle information of the second rotating platform 30 detected by the tilt angle detection mechanism 50, and when the tilt angle detection mechanism 50 detects that the tilt angle of the second rotating platform 30 reaches the expected value, the controller 60 controls the driving mechanism 40 to stop working.

[0044] Thus, the controller 60 controls the driving mechanism 40 to drive the first rotating platform 20 and the second rotating platform 30 to rotate, so that the fuel cell 1 is in a tilted state. When the tilt angle detection mechanism 50 detects that the tilt angles of the first rotating platform 20 and the second rotating platform 30 reach the expected value, the controller 60 controls the driving mechanism 40 to stop working, thereby automatically adjusting the tilt angles of the first rotating platform 20 and the second rotating platform 30 to complete the tilt test of the fuel cell 1. The tilt test device 2 can achieve automatic tilting in one step without multiple adjustments. The tilt angle of the tilt test device 2 is precisely controllable, which improves the test efficiency and the accuracy of the test.
