Detailed Implementation

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see the appendix Figure 1-6This utility model provides a tilt angle testing fixture 100 for a photovoltaic tracking bracket control box, including a left support plate 1, a right support plate 2, a connecting plate 3, a fixing plate 4, a PCBA assembly 5, and an angle adjustment mechanism 6. The left support plate 1 and the right support plate 2 are arranged opposite to each other and connected by the connecting plate 3. The PCBA assembly 5 is installed on the bottom surface of the fixing plate 4. The fixing plate 4 is connected to the left support plate 1 or the right support plate 2 through the angle adjustment mechanism 6. By adjusting the angle adjustment mechanism 6, the tilt angle of the fixing plate 4 can be changed to realize the tilt angle test of the PCBA assembly 5.

[0027] This utility model's test fixture 100 modularly combines a left support plate 1, a right support plate 2, a connecting plate 3, a fixing plate 4, a PCBA assembly 5, and an angle adjustment mechanism 6 to form an independent and dedicated photovoltaic tracking bracket control box test platform. This transfers tilt angle testing from complex on-site brackets to a simple fixture, fundamentally solving the problems of high test site requirements and cumbersome procedures, and laying the foundation for achieving fast and convenient angle adjustment.

[0028] In this utility model, the angle adjustment mechanism 6 includes a left screw array 61 disposed on the left support plate 1 and a right screw array disposed on the right support plate 2. By selecting screws at different positions in the left screw array 61 and the right screw array to lock with the fixing plate 4, the fixing plate 4 can be adjusted in multiple angles within the range of 0-60°. The operation is intuitive and the structure is simple.

[0029] In this utility model, reference is made to the appendix. Figure 2 As shown, the left screw array 61 includes multiple first right adjusting screws 613 located on the right side of the left support plate 1, distributed in an arc or straight line, with the line connecting the first left screw 611 and the first right screw 612 as the reference side and the first left screw 611 as the reference vertex. The lines connecting the multiple first right adjusting screws 613 and the first left screw 611 form angles of 15°, 30°, 45°, and 60° with the reference side, respectively. The right screw array includes multiple second right adjusting screws 623 located on the right side of the right support plate 2, distributed in an arc or straight line, with the line connecting the second left screw 621 and the second right screw 622 as the reference side and the second left screw 621 as the reference vertex. The lines connecting the multiple second right adjusting screws 623 and the second left screw 621 form angles of 15°, 30°, 45°, and 60° with the reference side, respectively. The screw distribution on the right side of the left support plate 1 and the right support plate 2 is specifically defined, enabling unidirectional angle adjustment and simulating the unidirectional rotation of the photovoltaic support. By precisely corresponding the screw positions to specific angles (15°, 30°, 45°, 60°), the accuracy and repeatability of angle adjustment are ensured, avoiding errors caused by adjustment based on experience.

[0030] In this invention, the left screw array 61 includes multiple first left adjusting screws 614 located on the left side of the left support plate 1, arranged in an arc or straight line, with the line connecting the first left screw 611 and the first right screw 612 as the reference side and the first right screw 612 as the reference vertex. The lines connecting the multiple first left adjusting screws 614 and the first right screw 612 form angles of 15°, 30°, 45°, and 60° with the reference side, respectively. The right screw array includes multiple second left adjusting screws 624 located on the left side of the right support plate 2, arranged in an arc or straight line, with the line connecting the second left screw 621 and the second right screw 622 as the reference side and the second right screw 622 as the reference vertex. The lines connecting the multiple second left adjusting screws 624 and the second right screw 622 form angles of 15°, 30°, 45°, and 60° with the reference side, respectively. Specifically, the screw distribution on the right side of the left support plate 1 and the left side of the right support plate 2 is defined, enabling bidirectional angle adjustment. This allows the test fixture 100 to simulate the pitching motion of the photovoltaic tracking bracket at different times of the day (such as morning and afternoon), greatly expanding the test coverage scenarios and improving the comprehensiveness and reliability of the test.

[0031] Preferably, the first right adjusting screw 613 pointing to 60° and the first left adjusting screw 614 pointing to 60° belong to the same screw. The second right adjusting screw 623 pointing to 60° and the second left adjusting screw 624 pointing to 60° belong to the same screw.

[0032] In this invention, all screws in the left screw array 61 and the right screw array are M10*20_GB85 screws. (See attached document.) Figure 4-5 As shown, the M10*20_GB85 screw includes a smooth section 7 located within the fixing plate 4 when tightened. When the M10*20_GB85 screw is tightened, the smooth section 7 smoothly engages with the inner wall of the screw hole in the fixing plate 4, reducing wear of the threads on the hole in the fixing plate 4, while providing more precise radial positioning, reducing gaps and wobble during angle adjustment, thereby further improving the stability of angle fixing and the accuracy of test results.

[0033] In this invention, the connecting plate 3 includes a first connecting plate 3 and a second connecting plate 3 arranged opposite to each other. Both ends of the first connecting plate 3 are fixedly connected to the left support plate 1 and the right support plate 2 by screws (M6-20_GB70), and both ends of the second connecting plate 3 are also fixedly connected to the left support plate 1 and the right support plate 2 by screws. The first connecting plate 3 and the second connecting plate 3 form a robust and stable frame structure for the left support plate 1 and the right support plate 2, effectively preventing deformation of the support structure caused by changes in the weight and position of the PCBA assembly 5 and the fixing plate 4 during testing. This ensures the stability of the test reference surface and thus guarantees the authenticity and reliability of the test data.

[0034] Preferably, both the first connecting plate 3 and the second connecting plate 3 have through holes 31 for the wire harness to pass through.

[0035] In this utility model, reference is made to the appendix. Figure 6 As shown, the PCBA assembly 5 is secured to the studs 41 of the fixing plate 4 with screws (M3-10), providing a secure connection and easy disassembly installation method. This ensures that the PCBA will not loosen or shift during testing; it also facilitates quick replacement of different PCBA assemblies 5 for testing, improving the versatility of the tooling and testing efficiency.

[0036] The tilt angle testing fixture 100 for the photovoltaic tracking bracket control box of this utility model has the following beneficial technical effects:

[0037] 1. By loosening and tightening the M10*20_GB85 screws, the angle of the fixing plate 4 can be adjusted, thereby adjusting the angle of the PCBA on the fixing plate 4 to achieve the purpose of testing the tilt angle; the operation is simple, the cost is low, the testing efficiency is high, and the material cost and time cost are saved.

[0038] 2. Angle positioning is achieved using a screw array, ensuring precise angle value fixation and avoiding human adjustment errors. The stable frame structure and M10*20_GB85 screws with 7 light segments ensure reliable angle fixation during testing, preventing wobbling, and resulting in good repeatability and high accuracy of test data.

[0039] 3. The entire testing process requires no complex tools or professional skills and can be completed by ordinary employees; the bidirectional angle adjustment capability enables it to simulate more actual working conditions and adapt to different testing needs; the modular design also facilitates the adaptation and testing of different PCBA components.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
