[0028] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0029] See Figure 1 A vibration simulation device provided in one embodiment of the present application includes a vibration module 10 and a driving module.

[0030] In one embodiment, see Figure 1 At least two vibration modules 10 are provided, and all vibration modules 10 are arranged along a first direction, with X representing the first direction. Each vibration module 10 includes at least two vibration members 11. In each vibration module 10, all vibration members 11 are arranged along a second direction, with the first direction intersecting with the second direction. Optionally, the first direction is perpendicular to the second direction, with Y representing the second direction. The output shaft of each vibration member 11 is provided with a connector 12 for connecting to a photovoltaic module, and the vibration member 11 is used to drive the photovoltaic module to vibrate.

[0031] During the test, the photovoltaic module is connected to all the connectors 12 and the vibrating member 11 is started. The vibrating member 11 drives the photovoltaic module to vibrate, so as to simulate the photovoltaic module experiencing wind load or snow load in an outdoor environment.

[0032] Since the output end of the vibrator 11 is directly connected to the connector 12, the force generated by the vibrator 11 is directly transmitted to the photovoltaic module through the connector 12, which can reduce force conduction loss, avoid the risk of structural deformation, and improve stability.

[0033] Optionally, the vibrating member 11 is a cylinder, and the output shaft of the cylinder is provided with a connector 12. During testing, the photovoltaic module is connected to the connector 12, and the cylinder drives the photovoltaic module to move back and forth, thereby achieving vibration of the photovoltaic module. Optionally, the vibrating member 11 can also be a servo lifting mechanism, which is conducive to improving lifting accuracy. Optionally, the vibrating member 11 is a frequency-modulated vibration motor, and the output shaft of the frequency-modulated vibration motor is provided with a connector 12. The frequency-modulated vibration motor can adjust the amplitude and vibration frequency of the photovoltaic module.

[0034] Optionally, see Figure 1 The connecting member 12 is a suction cup, and the suction cup is provided with a suction hole. The vacuuming device vacuums the gap between the suction cup and the photovoltaic module through the suction hole, so that the suction cup can be adsorbed on the photovoltaic module.

[0035] In one embodiment, see Figures 3 to 6 The driving module is connected to the vibration module 10, and the driving module is used to drive the vibration member 11 to move along the first direction and the second direction so that the area surrounded by all the vibration members 11 is adapted to the size of the photovoltaic module.

[0036] In this way, the driving module can drive the corresponding vibrating element 11 to move along the first direction and the second direction according to the size of the photovoltaic component, so that the area enclosed by all the vibrating elements 11 is adapted to the size of the photovoltaic component. In this way, the vibration simulation device can simulate the vibration deformation of photovoltaic components of different sizes under outdoor wind loads or snow loads and other environments, thereby improving the compatibility of the vibration simulation device.

[0037] Furthermore, driven by the driving module, the vibrating element 11 can move along the first direction and the second direction. Thus, the vibrating element 11 can be arranged in an array so that the vibration force acting on the photovoltaic module is evenly distributed, thereby improving the stability of the vibration simulation device.

[0038] In one embodiment, the drive module includes a first drive component and a second drive component. The first drive component is connected to the vibration module 10, and the first drive component is used to drive the vibration module 10 to move in the first direction. There are at least two second drive components, and all second drive components are arranged in a one-to-one correspondence with all vibration modules 10. The second drive component is connected to the vibrating member 11, and the second drive component is used to drive the vibrating member 11 to move in the second direction. In this way, the first drive component can drive the vibrating member 11 to move in the first direction, and / or the second drive component can drive the vibrating member 11 to move in the second direction, so that the area enclosed by all the vibrating members 11 is adapted to the size of the photovoltaic module. In this way, the vibration simulation device can simulate the vibration deformation of photovoltaic modules of different sizes under outdoor wind loads or snow loads and other environments, thereby improving the compatibility of the vibration simulation device. In addition, the moved vibrating members 11 can be arranged in an array so that the vibration force acting on the photovoltaic module is evenly distributed.

Wherein, the first drive member is a motor or a hand crank. In this way, the first drive member can drive the first bidirectional screw to rotate around its own axis, thereby driving the vibration modules 10 at both ends along the first direction to approach or move away from each other, thereby realizing the adjustment of the position of the vibration modules 10 at both ends along the first direction in the first direction.

[0040] Furthermore, the second drive assembly includes a second drive member and a second bidirectional screw. The second drive member is connected to the second bidirectional screw, and the second bidirectional screw is extended along the second direction.

The vibrating member 11 at one end along the second direction is connected to the third threaded portion, and the vibrating member 11 at the other end along the second direction is connected to the fourth threaded portion. Among them, the second drive member is a motor or a hand crank. In this way, the second drive member can drive the second bidirectional screw to rotate around its own axis, thereby driving the vibrating members 11 at both ends along the second direction to approach or move away from each other, thereby realizing the adjustment of the position of the vibrating members 11 at both ends along the second direction in the second direction.

[0041] It should be noted that if the number of vibration modules 10 and vibration members 11 is less than or equal to 3, the first driving member cooperates with the first bidirectional screw rod to adjust the distance between two adjacent vibration modules 10 in the first direction; the second driving member cooperates with the second bidirectional screw rod to adjust the distance between two adjacent vibration members 11 in the second direction.

[0042] It should be noted that if the number of vibration modules 10 and vibration members 11 is greater than 3, the first driving member cooperates with the first bidirectional screw rod and can only drive the vibration modules 10 at both ends along the first direction to move, while the vibration module 10 in the middle along the first direction is fixed; the second driving member cooperates with the second bidirectional screw rod and can only drive the vibration members 11 at both ends along the second direction to move, while the vibration member 11 in the middle along the second direction is fixed.

The output end of the first drive member is provided with a first gear, and the first gear is engaged with the first rack to drive the vibration module 10 to move along the first direction. The first drive member is a motor or a hand crank. In this way, according to the length of the photovoltaic component in the first direction and the vibration position, the corresponding first drive member is started, and the first drive member drives the first gear to move on the first rack to adjust the position of the vibration module 10 in the first direction.

[0044] Furthermore, the second drive assembly includes a second rack and a second drive member. The second rack is arranged along the second direction. In each second drive assembly, there are at least two second drive members, and all second drive members are arranged in a one-to-one correspondence with all vibrating members 11. The output end of the second drive member is provided with a second gear, and the second gear is engaged with the second rack to drive the vibrating member 11 to move along the second direction. The second drive member is a motor or a hand crank. In this way, according to the length of the photovoltaic assembly in the second direction and the vibration position, the corresponding second drive member is started, and the second drive member drives the second gear to move on the second rack to adjust the position of the vibrating member 11 in the second direction.

[0045] In this way, under the action of the first driving member, the first rack, the first gear, the second driving member, the second rack and the second gear, all the vibrating members 11 can move along the first direction and the second direction, thereby improving the flexibility of adjusting the position of the vibrating member 11.

[0046] Optionally, the first drive assembly includes a first drive member, a first transmission wheel, a second transmission wheel, and a first transmission belt. The first transmission wheel and the second transmission wheel are spaced apart along the first direction, the first transmission belt passes around the first transmission wheel and the second transmission wheel, and the first transmission wheel is connected to the first drive member.

[0047] Specifically, there are P vibration modules 10, where P is an integer ≥ 2. If P is an even number, the first drive assembly is provided with P / 2, and every two vibration modules 10 are connected to both sides of a first transmission belt along the first direction; if P is an odd number, the first drive assembly is provided with (P-1) / 2, and the (P+1) / 2th vibration module 10 is fixedly arranged along the first direction. Among the remaining vibration modules 10, every two vibration modules 10 are respectively connected to both sides of a first transmission belt along the first direction. Alternatively, the first drive assembly may have one vibration module 10. If P is an even number, the first to P / 2th vibration modules 10 are connected to one side of the first transmission belt along the first direction, and the (P / 2)+1th to Pth vibration modules 10 are connected to the other side of the first transmission belt along the first direction. If P is an odd number, the first to (P-1) / 2th vibration modules 10 are connected to one side of the first transmission belt along the first direction, and the [(P+1) / 2]+1th to Pth vibration modules 10 are connected to the other side of the first transmission belt along the first direction. Alternatively, the vibration modules 10 at both ends along the first direction are respectively connected to both sides of the first transmission belt along the first direction.

[0048] Furthermore, the second drive assembly includes a second drive member, a third transmission wheel, a fourth transmission wheel, and a second transmission belt. The third transmission wheel and the fourth transmission wheel are spaced apart along the second direction, the second transmission belt passes around the third transmission wheel and the fourth transmission wheel, and the third transmission wheel is connected to the second drive member.

[0049] Specifically, the vibration module 10 includes Q vibrators 11, where Q is an integer ≥ 2. If Q is an even number, the second drive assembly includes Q / 2 vibrators 11. In each vibration module 10, every two vibrators 11 are connected to opposite sides of a second transmission belt along the second direction. If Q is an odd number, the second drive assembly includes (Q-1) / 2 vibrators. In each vibration module 10, the (Q+1) / 2th vibrator 11 is fixedly disposed along the second direction. In each vibration module 10, every two vibrators 11 are connected to opposite sides of a second transmission belt along the first direction. Alternatively, the second drive assembly is equipped with one vibrating element 11. If Q is an even number, the first to Q / 2th vibrating elements 11 are connected to one side of the second transmission belt along the second direction, and the (Q / 2)+1th to Qth vibrating elements 11 are connected to the other side of the second transmission belt along the second direction.

Alternatively, the vibrating elements 11 at both ends along the second direction are respectively connected to both sides of the second transmission belt along the second direction.

[0050] In one embodiment, see Figure 1The vibration simulation device also includes a first guide member and a second guide member 40. The first guide member is extended along the first direction, and the second guide member 40 is extended along the second direction. There are at least two second guide members 40, and all second guide members 40 are movably mounted on the first guide member, and all second guide members 40 are arranged along the first direction. All vibration modules 10 are mounted on all second guide members 40 in a one-to-one correspondence, and each vibrator 11 is movably mounted on the second guide rail 40. In this way, by providing the first guide member and the second guide member 40, the movement of the vibrator 11 along the first direction and the second direction is guided, thereby avoiding the deviation, shaking and other unstable phenomena of the vibrator 11 and improving the stability of the movement of the vibrator 11.

[0051] Specifically, each second guide member 40 is provided with at least two sliding members 41 , and the sides of all the vibrating members 11 facing away from the connecting member 12 are connected to all the sliding members 41 in a one-to-one correspondence.

[0052] Optionally, the first guide member is one of a guide rail and a guide groove, and the second guide member 40 is one of a guide rail and a guide groove.

[0053] In one embodiment, at least two first guide members are provided, and all first guide members are spaced apart along the second direction. Thus, the second guide member 40 is guided by at least two first guide members, which is beneficial to improving the stability of the movement of the second guide member 40.

[0054] Optionally, three first guide members are provided, and the three first guide members are spaced apart along the second direction. The two ends of the second guide member 40 along the second direction are respectively connected to two of the first guide members in a one-to-one correspondence, and the middle portion of the second guide member 40 along the second direction is connected to another first guide member.

[0055] In one embodiment, see Figure 1 , there are three second guide members 40, each of which is equipped with three vibrating members 11. This arrangement creates a nine-point vibration simulation device, which helps improve the uniformity of vibration force distribution. Of course, in other embodiments, the number of second guide members 40 and the number of vibrating members 11 on the second guide members 40 can be increased based on actual needs.

[0056] In one embodiment, see Figure 2 When the vibration simulation device is used in an environmental chamber, it also includes a sealing frame 50. The sealing frame 50 is disposed within the environmental chamber and seals against the inner wall of the environmental chamber to separate the interior space of the environmental chamber into a mounting chamber and a sealed chamber. The vibration module 10 and the drive module are both disposed within the mounting chamber, and the photovoltaic module is disposed within the sealed chamber. Thus, by disposing the sealing frame 50 within the environmental chamber, the sealing frame 50 can prevent the temperature and humidity within the sealed chamber from escaping.

[0057] It should be noted that when the vibration simulation device is used in a natural environment, the sealing frame 50 can be removed and only the vibration module 10 and the driving module can be used for testing.

[0058] It should be noted that the sealing frame 50 can be made of any thermal insulation material that meets the temperature tolerance requirements.

[0059] Optionally, the sealing frame 50 is square in shape, for example, the sealing frame 50 is square or rectangular in shape.

[0060] Further, see Figure 2 The sealing frame 50 is provided with a through-hole 521 adapted for the connector 12. Multiple through-holes 521 are provided, and all through-holes 521 are provided in a one-to-one correspondence with all connectors 12. During testing, the photovoltaic module is placed within the sealed cavity, and the vibration module 10 is placed within the mounting cavity. The through-holes 521 provided in the sealing frame 50 allow the connector 12 to pass through the through-holes 521 and connect to the photovoltaic module. Furthermore, the connector 12 is placed within the through-holes 521, thereby blocking the through-holes 521 and achieving a sealing effect.

[0061] It should be noted that the shape of the perforation 521 is adapted to the shape of the connector 12. Optionally, the shape of the perforation 521 is circular. Of course, in other embodiments, the shape of the perforation 521 may also be square, etc., and is not limited thereto.

[0062] In one embodiment, see Figure 2 and Figure 7 The sealing frame 50 includes a frame body 51 and a sealing block 52. The frame body 51 is provided with a sealing hole 511 adapted to the sealing block 52. It is understood that the size of the sealing hole 511 is equal to the size of the sealing block 52. In this way, after the sealing block 52 is placed in the sealing hole 511, the side of the sealing block 52 can be sealed with the hole wall of the sealing hole 511, thereby ensuring the sealing performance of the sealing frame 50.

[0063] It should be noted that the number and shape of the sealing holes 511 vary with the number of the vibrating elements 11 , as follows:

[0064] The frame 51 is provided with M rows of holes in the first direction, and N columns of holes in the second direction, where M and N are integers ≥ 2.

[0065] See Figures 3 to 6The four right-angled locations of the frame 51 are all square sealing holes 511. M-2 rectangular sealing holes 511 are located between the square sealing holes 511 at both ends along the first direction. These rectangular sealing holes 511 extend along the second direction. N-2 rectangular sealing holes 511 are located between the square sealing holes 511 at both ends along the second direction. These rectangular sealing holes 511 extend along the first direction, with the length of each rectangular sealing hole 511 being equal to the side length of the square sealing hole 511. The remaining holes are either square sealing holes 511 or through-holes 521 that mate with the connector 12.

[0066] Optionally, when M=2 and N=2, four sealing holes 511 are provided, and the four sealing holes 511 are respectively provided at four right-angle positions of the frame body 51 , and the sealing holes 511 are square holes.

[0067] Optionally, if M ≥ 3 and N = 2, the number of sealing holes 511 is equal to the number of vibrating elements 11. A square hole is provided at each of the four right-angled positions of the frame 51. Between the square holes at both ends along the first direction are (M-2) rectangular holes, extending along the second direction. The side length of the square hole is equal to the length of the rectangular hole along the second direction.

[0068] Optionally, when M=3 and N≥2, the number of sealing holes 511 is equal to the number of vibrating members 11. A square hole is provided at each of the four right-angled positions of the frame 51, and (N-2) rectangular holes are provided between the square holes at both ends along the second direction, with the rectangular holes extending along the first direction.

[0069] Optionally, when M ≥ 3 and N ≥ 3, each of the four right-angled positions of the frame 51 is provided with a square hole. Between the square holes at both ends along the first direction are (M-2) rectangular holes, with the rectangular hole between the square holes at both ends along the first direction extending in the second direction. Between the square holes at both ends along the second direction are (N-2) rectangular holes, with the rectangular hole between the square holes at both ends along the second direction extending in the first direction. The remaining holes are sealing holes 511 for the square holes. Of course, in other embodiments, the remaining holes may also be through-holes 521 adapted to the connector 12.

[0070] Furthermore, there are multiple sealing blocks 52, namely multiple square sealing blocks 52 and multiple rectangular sealing blocks 52. All sealing blocks 52 are arranged in a one-to-one correspondence within all sealing holes 511. A perforation 521 is provided at a right angle of the square sealing block 52, and a perforation 521 is provided at one end of the rectangular sealing block 52 along its extension direction. By adjusting the direction of the square sealing block, the position of the perforation 521 can be adjusted, enabling the connector 12 to switch between the four right-angle positions of the square hole. By adjusting the direction of the rectangular sealing block 52, the position of the perforation 521 can be adjusted, enabling the connector 12 to switch between the two ends of the rectangular hole along its extension direction. This helps to improve the compatibility of the vibration simulation device.

[0071] In one embodiment, see Figure 2 The sealing block 52 is provided with a handle 522. Specifically, the handle 522 is located on the side of the sealing block 52 facing away from the drive module. To remove the sealing block 52, the operator grasps the handle 522 and pulls the sealing block 52 away from the frame 51, thereby removing the sealing block 52 from the sealing hole 511. The provision of the handle 522 facilitates removal of the sealing block 52.

[0072] The present application also provides a testing device, comprising a detection device and the above-mentioned vibration simulation device, wherein the detection device is used to detect the photovoltaic component.

[0073] Optionally, the detection device includes an EL (electroluminescent) camera, and the EL camera photographs the photovoltaic module.

[0074] In the above-mentioned test device, the driving module can drive the corresponding vibrating element 11 to move along the first direction and the second direction according to the size of the photovoltaic component, so that the area enclosed by all the vibrating elements 11 is adapted to the size of the photovoltaic component. In this way, the vibration simulation device can simulate the vibration and deformation of photovoltaic components of different sizes under outdoor wind load or snow load environments, thereby improving the compatibility of the vibration simulation device.

[0075] Furthermore, driven by the driving module, the vibrating element 11 can move along the first direction and the second direction. Thus, the vibrating element 11 can be arranged in an array so that the vibration force acting on the photovoltaic module is evenly distributed, thereby improving the stability of the vibration simulation device.
