Description

Technical Field

[0001] The utility model relates to the technical field of quality detection, and more particularly to a detection platform which is easy to adjust. Background Art

[0002] A microinverter generally refers to an inverter with a power of 1000 watts or less and module-level MPPT in a photovoltaic power generation system. The full name is micro photovoltaic grid-connected inverter. The "micro" designation is relative to traditional centralized inverters. Traditional photovoltaic inverters connect the direct current (DC) generated by all photovoltaic cells in sunlight in series and parallel, then use an inverter to convert the DC into AC for grid connection. Microinverters, on the other hand, perform inversion for each module. Their advantage is independent MPPT control for each module, significantly improving overall efficiency while avoiding the issues of centralized inverters, such as high DC voltage, poor low-light performance, and the "barrel effect."

[0003] After manufacturing, microinverters require vibration testing to simulate the vibration environments they may encounter during transportation and use, assessing their stability and reliability under these conditions. However, existing vibration testing equipment often uses a single vibration pattern, which differs from the actual vibrations of a vehicle, resulting in poor test results. Utility Model Content

Therefore, it should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0021] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0022] Reference Figures 1 to 3 The utility model provides a technical solution: a test bench that is easy to adjust, comprising a base 1, a plurality of support columns 2 are fixedly connected to the base 1, a plurality of support columns 2 are fixedly connected to springs 3, and the ends of the plurality of springs 3 away from the base 1 are fixedly connected to the support platform 4. Figure 1 , the base 1 supports multiple support columns 2, and multiple support columns 2 support the support platform 4 through the springs 3 thereon. A horizontal plate 5 is provided under the support platform 4, and the two ends of the horizontal plate 5 are fixedly connected to the wheel frame 6. The two wheel frames 6 are rotatably connected to the transmission shaft 7, and the two transmission shafts 7 are fixedly connected to the eccentric wheels 8. The two eccentric wheels 8 are in conflict with the support platform 4. Two motors 9 are installed on the horizontal plate 5, and the output shafts of the two motors 9 are connected to the two transmission shafts 7 through couplings.

[0023] like Figure 1 and Figure 2The output shaft of the motor 9 can drive the transmission shaft 7 to rotate, and the transmission shaft 7 can drive the eccentric wheel 8 thereon to rotate;

[0024] When the two eccentric wheels 8 rotate synchronously and at the same speed, and cooperate with multiple springs 3, the two eccentric wheels 8 can push the support platform 4 to move up and down, thereby driving the support platform 4 to vibrate;

[0025] When the rotational speeds of the two eccentric wheels 8 are different, the two ends of the platform 4 are pushed by the two eccentric wheels 8 at different times, and during the test, the rotational speeds of the two eccentric wheels 8 can be changed multiple times, thereby truly simulating the bumps on both sides of the vehicle body during transportation (because the number and intensity of bumps on both sides of the vehicle body during transportation will be different), and the test data obtained is more realistic and the test effect is better.

[0026] Specifically, each of the eccentric wheels 8 is in contact with two rollers 10, and the plurality of rollers 10 are rotatably connected to the support platform 4;

[0027] like Figure 2 and Figure 3 The eccentric wheel 8 contacts the roller 10, thereby driving the support platform 4 to vibrate, and the eccentric wheel 8 can drive the roller 10 to rotate, thereby reducing the friction damage of the eccentric wheel 8 and extending its service life.

[0028] Specifically, an electric cylinder 11 is installed on the base 1, and the piston rod of the electric cylinder 11 is fixedly connected to the horizontal plate 5. Figure 2 , the electric cylinder 11 can drive the horizontal plate 5 to move up and down, thereby adjusting the distance between the eccentric wheel 8 and the roller 10;

[0029] When the distance between the eccentric wheel 8 and the roller 10 decreases, the vibration amplitude of the support platform 4 will decrease;

[0030] When the distance between the eccentric wheel 8 and the roller 10 increases, the vibration amplitude of the support platform 4 will increase, thereby providing a more complex vibration environment and further improving the test effect.

[0031] Specifically, a plurality of guide rods 12 are fixedly connected to the horizontal plate 5, and a plurality of vertical frames 13 are slidably connected to the plurality of guide rods 12, and the plurality of vertical frames 13 are fixedly connected to the base 1. Figure 2 The two ends of the horizontal plate 5 are supported by two guide rods 12 to improve the stability of the horizontal plate 5.

[0032] Specifically, a guardrail 14 is fixedly connected to the support platform 4 to prevent the test products on the support platform 4 from falling.

[0033] Specifically, the plurality of support columns 2 are respectively located at the four corners of the base 1 , and the plurality of springs 3 are respectively located at the four corners of the support platform 4 .

[0034] Working principle: the output shaft of the motor 9 can drive the transmission shaft 7 to rotate, and the transmission shaft 7 can drive the eccentric wheel 8 thereon to rotate; when the two eccentric wheels 8 rotate synchronously and at the same speed, and cooperate with multiple springs 3, the two eccentric wheels 8 can push the platform 4 to move up and down, thereby driving the platform 4 to vibrate; when the rotational speeds of the two eccentric wheels 8 are different, the number of times the two ends of the platform 4 are pushed by the two eccentric wheels 8 is different, and during the test process, the rotational speeds of the two eccentric wheels 8 can be changed multiple times, thereby truly simulating the bumps on both sides of the vehicle body during transportation.

[0035] It should be noted that the electrical components appearing in this application document are all electrically connected to the external main controller and 220V AC power, and the main controller can be a processor, an alarm module, a drive module, etc., which plays a role in controlling conventional known equipment.
