[0016] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] This utility model provides a vibration testing fixture for photovoltaic panel modules, including: a vibration testing carrier and a photovoltaic panel module fixing device. The photovoltaic panel module fixing device is composed of several cylinder-driven suction cup fixing parts 4. The top of the several cylinder-driven suction cup fixing parts 4 is fixed by a movable frame that can move up and down. The vibration testing carrier includes a base frame 1. Several uprights 2 are fixedly connected to the top of the base frame 1. A top frame 5 is slidably sleeved on the side wall of the several uprights 2. A vibration adjustable drive device 3 is provided on the top of the base frame 1. The output end of the vibration adjustable drive device 3 is fixedly connected to the bottom of the top frame 5. The vibration adjustable drive device 3 is used to drive the top frame 5 to move up and down.

[0018] The cylinder-driven suction cup fixing component 4 is a fixing component that uses the operation of the cylinder to draw air from the suction cup to generate suction force, which is used to attach the photovoltaic panel module. The movable frame that can move up and down can avoid generating opposing forces on the vibration test carrier and avoid breaking or damaging the photovoltaic panel module. In use, the photovoltaic panel module is fixed on the top of the top frame 5 by the cylinder-driven suction cup fixing component 4. The vibration adjustable drive device 3 drives the top frame 5 to move up and down quickly, thereby achieving the vibration simulation test effect.

[0019] Furthermore, the vibration adjustable drive device 3 includes an adjustable rotation speed motor 31 and a horizontal shaft 33. The output end of the adjustable rotation speed motor 31 is fixedly connected to a transmission shaft 32. The other end of the transmission shaft 32 is connected to the horizontal shaft 33 through a vertical transmission component 34. Two support blocks 35 are rotatably sleeved on the side wall of the horizontal shaft 33. The support blocks 35 are fixedly installed on the top of the base frame 1. The two ends of the horizontal shaft 33 are respectively connected to the bottom of the top frame 5 through two upper and lower floating arms.

[0020] In use, the adjustable rotation speed motor 31 outputs rotational force, which, under the transmission action of the vertical transmission component 34, causes the horizontal shaft 33 to rotate. The rotation of the horizontal shaft 33 drives the two upper and lower floating arms to perform up and down work, causing the top frame 5 to vibrate up and down. The vibration frequency of the top frame 5 is controlled by adjusting the rotation speed of the adjustable rotation speed motor 31.

[0021] Furthermore, the vertical transmission component 34 includes, but is not limited to: a bevel gear transmission assembly and a worm gear transmission assembly.

[0022] Furthermore, the upper and lower floating arms include a main rotating block 36 and a secondary rotating block 38. The secondary rotating block 38 is located above the main rotating block 36. The inner sides of the main rotating block 36 and the secondary rotating block 38 are respectively provided with a first convex shaft 37 and a second convex shaft 39. The first convex shaft 37 and the second convex shaft 39 are connected by a transmission arm 310. The first convex shaft 37 is located at the eccentric position of the horizontal axis 33. The main rotating block 36 can adjust the eccentric distance between the first convex shaft 37 and the horizontal axis 33. The main rotating block 36 is fixedly connected to the shaft end of the horizontal axis 33, and the top of the secondary rotating block 38 is fixedly connected to the bottom of the top frame 5.

[0023] When the horizontal shaft 33 rotates, it drives the main rotating block 36 to rotate. Since the convex shaft 37 is located at the eccentric position of the horizontal shaft 33 axis, the auxiliary rotating block 38 can float up and down under the transmission of the transmission arm 310, thereby controlling the up and down displacement vibration of the top frame 5. By adjusting the eccentric distance of the convex shaft 37 through the main rotating block 36, the up and down floating distance of the auxiliary rotating block 38 can be adjusted, thereby controlling the amplitude of the top frame 5.

[0024] Furthermore, the main rotating block 36 includes a main body block 361, with a slide rail inside the main body block 361 and a through groove on one side of the main body block 361 connecting to the slide rail. A sliding block 364 is slidably sleeved in the slide rail of the main body block 361. A convex shaft 37 passes through the through groove and is fixedly connected to the sliding block 364. Fixing brackets 362 are fixedly installed at the top and bottom of the main body block 361. Threaded rods 363 are rotatably sleeved inside the two fixing brackets 362. The sliding block 364 is threadedly sleeved on the side wall of the threaded rod 363. A knob is connected to the top of the threaded rod 363 through the fixing bracket 362.

[0025] In use, rotating the knob drives the threaded rod 363 to rotate, and the sliding block 364 moves up and down under the action of the threaded structure, which in turn drives the cam shaft 37 to move up and down, thus achieving the effect of adjusting the eccentric distance.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. This utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
