In order to achieve the purpose, the flexible gasket is arranged in the first penetrating channel of the carrier, and the at least one penetrating seam is formed in the flexible gasket, so that on one hand, impact sources of different sizes can be conveniently placed on the flexible gasket, and the impact sources are prevented from directly sliding off when the size of the impact sources is smaller than that of the first penetrating channel; and on the other hand, the impact source can penetrate through the penetrating seam to impact on the to-be-tested sample under the condition that the impact source is subjected to external force, so that the effectiveness of the impact test is ensured. In addition, when the carrier is used for testing different sizes of impact sources of the to-be-tested sample, the matched carrier does not need to be replaced frequently, and the testing efficiency of the impact test is improved.

Description

Technical Field

[0001] This utility model relates to the technical field of impact testing devices, specifically providing a vehicle and an impact testing device. Background Technology

[0002] An impact test apparatus is a testing device that applies impact force to a test sample to evaluate its impact resistance. Taking photovoltaic modules as an example, in practical applications, photovoltaic modules may also be subjected to impacts from sources such as gravel and hail, affecting their lifespan. Therefore, simulating the impact scenarios that photovoltaic modules might encounter in real-world applications and conducting impact tests on them is particularly important.

[0003] Currently, when conducting impact tests on photovoltaic modules using impact testing equipment, a carrier is required to hold the impact source. This carrier has a channel that allows the impact source to pass through, enabling it to impact the photovoltaic module under external force. However, current carriers have extremely stringent requirements regarding the size of the impact source; it must match the size of the channel on the carrier to conduct the impact test. If the impact source is too large, it may not be able to pass through the channel under force, while if it is too small, the impact source will pass through the channel without external force, failing to achieve the desired testing effect. Therefore, when impact tests are required on photovoltaic modules using impact sources of different sizes, it is necessary to frequently change carriers that match the impact source size, which undoubtedly greatly reduces the testing efficiency of impact testing.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0013] This application also provides an impact testing apparatus, comprising:

[0014] The vehicle described in any of the above preferred technical solutions;

[0015] A drive mechanism configured to apply an external force to an impact source on the flexible pad, such that the impact source can pass through the penetration seam and strike the test sample.

[0019] In the preferred embodiment of the above-mentioned impact testing device, the impact testing device further includes:

[0020] A connecting frame, on which the platform and the driving mechanism are mounted;

[0021] The stage and / or the drive mechanism are movably mounted on the connecting frame so that they can move closer or further apart.

[0022] In the preferred embodiment of the above-mentioned impact test apparatus, the connecting frame is provided with a first slide rail or a first slide groove, and at least one of the platform and the driving mechanism is slidably connected to the first slide rail or the first slide groove; or

[0023] At least one of the platform and the drive mechanism is provided with a first slide rail or a first slide groove, and at least one of the platform and the drive mechanism is slidably connected to the connecting frame through the first slide rail or the first slide groove.

[0030] In the preferred embodiment of the above-mentioned impact test apparatus, one of the workbench and the connecting frame is provided with a third slide rail or a third slide groove, and the other is slidably connected to the third slide rail or the third slide groove.

[0031] In the preferred embodiment of the above-mentioned impact test device, the driving mechanism includes a pressure tank with a pressure chamber. The pressure tank is provided with an inlet and an outlet that communicate with the pressure chamber. The inlet is connected to a gas source, and the outlet is aligned with the penetration channel, so that the air pressure can be applied as an external force to the flexible pad as the impact source.

[0032] In the preferred embodiment of the above-mentioned impact test apparatus, the inlet and / or outlet of the pressure tank are provided with pressure regulating valves; and / or

[0033] A pressure detection device is installed inside the air pressure chamber.

[0034] Those skilled in the art will understand that the carrier of this application includes a carrier body and a flexible pad. By placing a flexible pad within a first penetration channel on the carrier body and having at least one penetration slit on the flexible pad, it is advantageous to place impact sources of different sizes on the flexible pad, preventing the impact source from slipping directly if its size is smaller than the size of the first penetration channel, thus making impact testing impossible. Furthermore, it allows the impact source to pass through the penetration slit and impact the test sample under external force, ensuring the effectiveness of the impact test. In addition, by using the carrier of this application to test the test sample with impact sources of different sizes, it is unnecessary to frequently change matching carriers, thus improving the efficiency of impact testing.

[0035] Furthermore, by converging at least two penetration slits on the flexible pad at a single point, it helps guide the impact source along a predetermined path, improving the accuracy and reliability of the test.

[0036] Those skilled in the art will understand that the impact testing apparatus of this application employs a driving mechanism to provide external force to the impact source on the flexible pad, enabling the impact source to pass through the penetration slit and impact the test sample, thereby ensuring the effectiveness of the impact test. Furthermore, since the flexible pad has at least one penetration slit, impact sources of different sizes can be placed on it, improving the efficiency of the impact test. It also prevents the impact source from slipping directly into the first penetration channel if its size is smaller, thus preventing the impact test from being conducted.

[0037] Furthermore, by setting a velocity detection element in the second penetration channel, the velocity of the impact source can be detected, which helps to evaluate the impact resistance performance of photovoltaic modules under different impact loads.

[0038] Furthermore, by movably mounting the stage and / or drive mechanism on the connecting frame, the impact test can be performed on the test sample when the stage and drive mechanism are close to each other, and when the stage and drive mechanism are far apart, it is convenient to change the impact source or carrier, thereby improving the efficiency of the impact test.

[0039] Furthermore, by movably mounting the connecting frame on the support, and movably mounting the support on the worktable, the stage and drive mechanism on the connecting frame can move in the first and second directions, which facilitates the impact testing device to conduct impact tests on different positions of the test sample, thereby enabling a more comprehensive evaluation of the impact resistance performance of the test sample.

[0040] Furthermore, by installing pressure regulating valves at the inlet and / or outlet of the pressure tank, the gas pressure can be adjusted to change the velocity of the impact source, thereby helping to evaluate the impact resistance performance of photovoltaic modules under different impact loads. Additionally, by installing pressure sensing elements within the pressure chamber, it is helpful to evaluate the impact resistance performance of photovoltaic modules under different pressures.

[0051] Preferred embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application. For example, although the following embodiments use photovoltaic modules as the test sample and gravel as the impact source for explanation and illustration, this is not restrictive. The technical solution of this utility model is equally applicable to other test samples and impact sources, and such changes in application do not deviate from the principles and scope of this utility model.

[0052] It should be noted that in the description of this application, terms such as "upper," "lower," "left," "right," "inner," and "outer," indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0053] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0054] See Figure 1 In existing impact testing devices, when conducting impact tests on photovoltaic modules, a carrier 100 loaded with crushed stone is required. This carrier 100 is typically cylindrical, with an axially oriented penetration channel 110 for the crushed stone to pass through, allowing it to impact the photovoltaic module under external force. However, current carriers 100 have extremely stringent requirements regarding the size of the crushed stone; it must match the size of the channel on the carrier 100 for the impact test to be conducted. If the crushed stone is too large, it may not be able to pass through the channel under force, while if it is too small, it will pass through the channel directly without external force, making the impact test impossible. Therefore, when impact tests on photovoltaic modules with crushed stone of different sizes are required, it is necessary to frequently change carriers 100 that match the size of the crushed stone, which undoubtedly greatly reduces the testing efficiency of the impact test.

[0055] To address the problem that the aforementioned impact testing device requires frequent replacement of the matching carrier 1 due to varying sizes of the gravel 8 during impact testing of photovoltaic modules 7, thus affecting testing efficiency, the impact testing device of this application includes a carrier 1 according to the following preferred embodiment.

[0056] See Figure 3-4 As shown, the carrier 1 of this utility model includes a carrier body 11 and a flexible pad 12. The carrier body 11 includes a first clamp 111 and a second clamp 112 arranged opposite to each other. Both the first clamp 111 and the second clamp 112 are cylindrical, and a flexible pad 12 is disposed between them. The first clamp 111 has a first channel 1111 along its axial direction, and the second clamp 112 has a second channel 1121 along its axial direction. The first channel 1111 and the second channel 1121 serve as a first through-channel 13, with their axes coinciding and having the same inner diameter. They are divided into two independent channels by the flexible pad 12, so that the first channel 1111 and the flexible pad 12 together form a space for accommodating gravel 8. This is beneficial for placing any gravel 8 with a size less than or equal to the inner diameter of the first channel 1111 in this space, improving the practicality of the carrier 1.

[0057] It should be noted that not only can the first channel 1111 and the flexible pad 12 form a space to accommodate the gravel 8, but the second channel 1121 and the flexible pad 12 can also form a space to accommodate the gravel 8. This means that the placement of the vehicle 1 is no longer restricted, thereby greatly improving the flexibility and practicality of the vehicle 1.

[0058] Of course, the specific configuration of the vehicle body 11 in this application is not fixed, and those skilled in the art can make adjustments as needed. For example, the first clamp 111 and the second clamp 112 can also be integrally formed, and a first annular platform is provided on the inner wall of the first through-channel 13, and a second annular platform is provided on the periphery of the flexible pad 12, so that the flexible pad 12 can be placed in the first through-channel 13 under the obstruction of the second annular platform. The vehicle 1 with this structure can also place gravel 8 with a size smaller than or equal to any range of the first through-channel 13.

[0059] Furthermore, the shapes of the first clamp 111 and the second clamp 112 are not fixed in this application, and those skilled in the art can adjust them as needed. For example, both the first clamp 111 and the second clamp 112 can be rectangular parallelepipeds. Additionally, this application does not limit the material of the first clamp 111 and the second clamp 112, as long as they are metal products. For example, both the first clamp 111 and the second clamp 112 can be made of aluminum alloy.

[0060] See next Figure 4-5The flexible pad 12 includes a bearing area 121 and a connecting area 122 surrounding the bearing area 121. The connecting area 122 is sandwiched between the first clamp 111 and the second clamp 112. The bearing area 121 corresponds to the first channel 1111 and the second channel 1121, located between the two channels, and the projections of the first channel 1111 and the second channel 1121 on the flexible pad 12 completely cover the bearing area 121. Two through-slits, namely the first through-slit 1211 and the second through-slit 1212, are formed on the bearing area 121, intersecting each other in a cross shape. The first through-slit 1211 and the second through-slit 1212 intersect on the axis of the first channel 1111 and the second channel 1121, which helps guide the gravel 8 along the axis of the first channel 1111 and the second channel 1121, improving the accuracy and reliability of the test. Both the first penetration seam 1211 and the second penetration seam 1212 extend to the edge of the bearing area 121, which facilitates the smooth passage of the crushed stone 8 under the action of external force, and reduces the resistance that the crushed stone 8 may encounter during the impact process, thus affecting the impact test results.

[0061] Of course, the number of penetration seams is not fixed in this application, and those skilled in the art can adjust it as needed. For example, the number of penetration seams can be one, three, or other numbers. If there are three penetration seams, the three seams intersect at one point. In addition, this application does not limit the material of the flexible pad 12, as long as the gravel 8 on it can pass through the penetration seams under the action of external force. For example, if the flexible pad 12 is made of rubber, using rubber as the material of the flexible pad 12 facilitates the automatic closure of the penetration seams after the gravel 8 passes through, preparing for the next impact test.

[0062] See next Figure 4-5 The first clamp 111 and the connection area 122 of the flexible gasket 12 are both provided with multiple connection holes, and the second clamp 112 is provided with multiple threaded holes. The multiple connection holes correspond one-to-one with the multiple threaded holes, so that the bolt 14 can be threadedly connected by passing through the connection holes on the first clamp 111, the connection holes on the connection area 122, and the threaded holes on the second clamp 112, thereby realizing the assembly of the carrier 1.

[0063] It should be noted that the connection method of the first clamp 111 and the second clamp 112 is not fixed in this application. Those skilled in the art can adjust it as needed, as long as the flexible gasket 12 can be firmly clamped between the first clamp 111 and the second clamp 112. For example, multiple connecting posts can be provided on the side of the first clamp 111 near the second clamp 112, and connecting grooves that engage with the multiple connecting posts can be provided on the side of the second clamp 112 near the first clamp 111. Alternatively, multiple connecting grooves can be provided on the side of the first clamp 111 near the second clamp 112, and connecting posts that engage with the multiple connecting posts can be provided on the side of the second clamp 112 near the first clamp 111. In this case, before assembling the first clamp 111 and the second clamp 112, the flexible gasket 12 can be installed onto the clamp with the connecting posts through its connecting holes before assembling the first clamp 111 and the second clamp 112.

[0064] See Figure 2 The impact test apparatus of this application includes, in addition to the aforementioned carrier 1, a drive mechanism, a platform 3, a bracket 5, a connecting frame 4, and a worktable 6. The worktable 6 is equipped with a third slide rail 61, which runs along a second direction (e.g., ...). Figure 2 The bracket 5 extends in the positive and negative directions indicated by the arrows in the Y direction. A third slider is provided at the bottom of the bracket 5, and the end of the third slider away from the bracket 5 is slidably mounted on the third slide rail 61, so that the bracket 5 can move along the third slide rail 61 in the second direction under the action of the third slider.

[0065] Of course, the method by which the bracket 5 is movably mounted on the worktable 6 is not fixed in this application, and those skilled in the art can adjust it according to the setting requirements. For example, a third slider can be set on the worktable 6, and a third slide rail can be set at the bottom of the bracket 5, which also facilitates the movement of the bracket 5 in the second direction. In other preferred embodiments, the setting of the third slide rail and the third slider is not necessary, and those skilled in the art can choose them as needed. In this case, the bracket 5 is fixed on the worktable 6.

[0066] See next Figure 2 The bracket 5 is provided with a second slide rail 51, which is along the first direction (e.g., Figure 2 Extending in the direction indicated by the arrows in the X direction (both positive and negative directions), a second slider is slidably mounted on the second slide rail 51. The end of the second slider away from the second slide rail 51 is connected to the connecting frame 4, allowing the connecting frame 4 to move along the second slide rail 51 in the first direction. The first and second directions are perpendicular to each other.

[0067] Of course, the method by which the connecting frame 4 is movably mounted on the bracket 5 is not fixed in this application, and those skilled in the art can adjust it according to the specific application scenario. For example, a second slide rail can be provided on the bracket 5, and a second slide rail extending along the first direction can be provided on the connecting frame 4, which also facilitates the movable mounting of the connecting frame 4 on the bracket 5.

[0068] See next Figure 2 A first slide rail 41 is provided on the side of the connecting frame 4 away from the bracket 5. The first slide rail 41 is along a third direction (e.g., Figure 2 The direction (in the positive and negative directions indicated by the arrows in the Z direction) extends, and the third direction is perpendicular to both the first and second directions. Two first sliders are slidably mounted on the first slide rail 41. One first slider, with its end away from the first slide rail 41, is connected to the platform 3, and the other first slider, with its end away from the first slide rail 41, is connected to the pressure tank 2 of the drive mechanism, allowing the platform 3 and the pressure tank 2 to move in the third direction. The pressure tank 2 has a pressure chamber containing a pressure detection element. The pressure tank 2 has an inlet 21 and an outlet 22 communicating with the pressure chamber. The inlet 21 is connected to the air source of the drive mechanism, and the outlet 22 has a pressure regulating valve aligned with the carrier 1 on the platform 3. This allows the platform 3 and the pressure tank 2 to move closer or further apart as they move along the first slide rail 41, and the carrier 1 and the outlet 22 of the pressure tank 2 also move closer or further apart accordingly. In addition, the setting of the pressure regulating valve helps to change the speed of the crushed stone 8, thereby enabling the evaluation of the impact resistance performance of the photovoltaic module 7 under different impact loads.

[0069] Of course, the way the pressure tank 2 and the platform 3 move closer or further apart is not fixed in this application, and those skilled in the art can adjust it as needed. For example, only one first slider is provided on the first slide rail 41. In this case, the end of the first slider away from the first slide rail 41 can be connected to the pressure tank 2, so that the pressure tank 2 can move closer or further away from the platform 3 fixed on the connecting frame 4 during the movement along the third direction. Alternatively, the end of the first slider away from the first slide rail 41 can also be connected to the platform 3, so that the platform 3 can move closer or further away from the pressure tank 2 fixed on the connecting frame 4 during the movement along the third direction.

[0070] Furthermore, the location of the pressure regulating valve is not fixed in this application, and those skilled in the art can adjust it as needed. For example, the pressure regulating valve can also be located at the inlet 21 of the pressure tank 2. It should also be noted that this application does not limit the specific type of pressure detection device, as long as the pressure detection device can detect the air pressure in the pressure chamber and facilitate the pressure regulating valve to adjust the air pressure through the pressure detection device. For example, the pressure detection device can be a pressure sensor.

[0071] Furthermore, the method by which the platform 3 and the pressure tank 2 are movably mounted on the connecting frame 4 is not fixed in this application, and those skilled in the art can adjust it according to the specific application scenario. For example, a first slide rail can be provided on the connecting frame 4, and a first slide rail extending along a first direction can be provided on the platform 3 and the pressure tank 2, which also facilitates the movable mounting of the platform 3 and the pressure tank 2 on the connecting frame 4.

[0072] See next Figure 2 and 6 The platform 3 is stepped, comprising a first support platform 31 and a second support platform 32. The first support platform 31 is positioned closer to the pressure tank 2, and the second support platform 32 is positioned further away from the pressure tank 2, located at the end of the first support platform 31 furthest from the pressure tank 2. Both the first support platform 31 and the second support platform 32 are cylindrical, with the outer diameter of the first support platform 31 being larger than that of the second support platform 32. The first support platform 31 has a receiving groove 311 for loading the carrier 1 at the end closer to the pressure tank 2. The second support platform 32 has a second through-channel 321 connected to the receiving groove 311, and the second through-channel 321, the receiving groove 311, and the second through-channel 321 are coaxial. The inner diameter of the receiving groove 311 is larger than the outer diameter of the second through-channel 321, which allows the platform to support the carrier 1 while also enabling the gravel 8 on the carrier 1 to impact the photovoltaic module 7 through the second through-channel 321. Furthermore, when the carrier 1 and the outlet 22 of the pressure tank 2 are close to each other, it is beneficial to conduct impact tests on the photovoltaic module 7 using gravel 8. When the carrier 1 and the outlet 22 of the pressure tank 2 are far apart, it is beneficial to place gravel 8 into the carrier 1 and conduct impact tests with gravel 8 of other sizes. In addition, a velocity detection device is provided in the second penetration channel 321. Through this velocity detection device, the velocity of the gravel 8 can be detected, thereby helping to accurately evaluate the impact resistance performance of the photovoltaic module 7 under different impact loads.

[0073] Of course, the specific configuration of the platform 3 is not fixed in this application, and those skilled in the art can adjust it as needed. For example, the platform 3 can also be cylindrical or cuboid in shape. In addition, the inclusion of the receiving slot 311 on the platform 3 is not mandatory, and those skilled in the art can choose it as needed. If the receiving slot 311 is not provided on the platform 3, the carrier 1 can be placed directly on the platform 3, and the second penetration channel 321 passes through both ends of the platform 3 in a third direction, thereby facilitating the passage of the gravel 8 on the carrier 1 and its impact on the photovoltaic module 7.

[0074] It should be noted that the inner diameter of the second penetration channel 321 can be the same as or larger than the inner diameter of the second channel 1121. This avoids the problem that if the inner diameter of the second penetration channel 321 is smaller than that of the second channel 1121, the crushed stone 8 may not be able to pass through the second penetration channel 321 under external force, thus preventing the impact test from being conducted. Furthermore, this application does not limit the relationship between the depth of the receiving groove 311 and the axial dimension of the carrier body 11, as long as the carrier 1 can be placed on the platform 3 and the carrier 1 on the platform 3 can be aligned with the output end of the drive mechanism. For example, the depth of the receiving groove 311 can be equal to, greater than, or less than the axial dimension of the carrier body 11. It should also be noted that this application does not limit the specific type of the speed detection element, as long as the speed detection element can detect the speed of the crushed stone 8. For example, the speed detection element can be a speed sensor.

[0075] Combination Figure 2-6 The working process of the impact testing apparatus of this application is described as follows:

[0076] After assembling the first clamp 111, the second clamp 112, and the flexible gasket 12 using bolts 14, they are placed in the receiving groove 311 of the support platform. Then, gravel 8 is placed into the space formed by the first channel 1111 and the flexible gasket 12. Next, the pressure regulating valve is adjusted to set the pressure tank 2 to the required pressure. Then, the platform 3 is moved so that the end carrying the carrier 1 aligns with the outlet 22 of the pressure tank 2. Simultaneously, the positions of the bracket 5 and the connecting frame 4 are adjusted to ensure that the gravel 8 is aligned with the target position of the photovoltaic module 7. Once everything is ready, the switch of the outlet 22 of the pressure tank 2 is turned on, releasing the pressure as an external force applied to the gravel 8 on the carrier 1. This external force causes the gravel 8 to pass through the penetration seam, then sequentially through the second channel 1121 and the second penetration channel 321, finally impacting the designated position of the photovoltaic module 7, thus completing one impact test. During this process, the corresponding pressure and velocity are recorded to evaluate the impact effect of these parameters on the photovoltaic module 7.
