[0089] Figure 1 Exemplarily, a display device 200 is shown. The display device 200 may include a device body 201. The device body 201 has opposite front and back surfaces, and four edges surrounding the front and back surfaces. When used to view the display device 200, the front surface of the device body 201 faces the user. Among the four edges, the two edges located on the upper and lower sides are oppositely arranged, and the other two edges located on the left and right sides are oppositely arranged. In addition, the display device 200 may further include a support 202, and the support 202 is connected to the device body 201 for supporting the device body 201.

[0090] The display device 200 will vibrate in various links such as production and assembly, packaging and transportation, and customer use. Long-term or intense vibration may affect the picture quality of the display device 200. In order to ensure that the display device 200 can be used normally in a real working environment, after manufacturing and before selling or shipping the product, it is necessary to perform reliability tests on the display device 200.

[0091] Currently, methods such as vibration testing and shock testing are usually used to conduct reliability tests on the display device 200 under different conditions. Vibration testing and shock testing are tests that simulate the severe jitter and instantaneous shock generated by the display device 200 due to environmental changes during transportation and use. During the testing process, it is first necessary to use a testing device to firmly fix the display device 200 on the vibration table, so as to ensure that as much vibration energy of the vibration table is transmitted to the display device 200 as possible and ensure the accuracy of the test results.

[0092] However, the testing devices in the related art have poor versatility and can only be applicable to a display device 200 of one size of the same model. For display devices 200 of different models or display devices 200 of different sizes of the same model, due to differences in structures such as the appearance and mounting hole positions, multiple dedicated testing devices need to be customized. Customizing testing devices not only has a high cost but also has a long design and production cycle, which not only increases the testing cost but also easily affects the testing progress.

[0093] To solve the above technical problems, embodiments of the present application provide a testing device and a system. The testing device and system provided by the embodiments of the present application will be introduced in detail below with reference to the accompanying drawings of the specification.

[0094] See Figure 2 and Figure 4 , the testing system provided by the embodiments of the present application includes a testing device 101 and a vibration table 102, and the testing device 101 is arranged on the vibration table 102.

[0095] The shaking table 102 is also known as a vibration exciter or a vibration generator. It is a device that obtains mechanical vibration by using electric, electro-hydraulic, piezoelectric or other principles. The principle of an electric shaking table is to input an excitation signal into a coil placed in a magnetic field to drive the worktable connected to the coil. Electric shaking tables are mainly used for vibration measurement above 10 Hz, and can generate a maximum force of 22,000 N. In the frequency range below 20 Hz, electro-hydraulic shaking tables are often used, and the nature of the vibration signal is controlled by an electro-servo system at this time. The hydraulic drive system can provide a large displacement and impact force. For example, the shaking table 102 can adopt the STI electromagnetic shaking table DC-2200, which can provide a maximum thrust of 22,000 N. Considering the weight of the shaking table 102 itself, the maximum acceleration can reach 10g during sinusoidal vibration and 30g during mechanical shock. The test device 101 arranged on the shaking table 102 can be one or more. For example, for a shaking table 102 with a tabletop length × width of 800 mm × 800 mm or more, two or more test devices 101 can be arranged. The multiple test devices 101 are arranged at intervals on the shaking table 102. In this way, multiple display devices 200 can be tested through one test, which can significantly improve the test efficiency and effectively accelerate the development progress of the display device 200.

[0096] See Figure 3 and Figure 5 , the test device 101 is applied to the display device 200. In other words, the test device 101 is used to fix the display device 200 on the shaking table 102 for reliability testing. The test device 101 includes two support components 1, two limiting components 2, and a clamping component 3. The two support components 1 can be arranged on the shaking table 102 with adjustable positions along the first direction X to clamp the two opposite edges of the device body 201 along the first direction X; the two limiting components 2 can be arranged on the support components 1 with adjustable positions along the second direction Z to clamp the two opposite edges of the device body 201 along the second direction Z; wherein, the second direction Z is perpendicular to the first direction X; the clamping component 3 is located on one side of the support component 1 and is connected to the support component 1; at least one of the limiting component 2 and the support component 1 abuts against the front surface of the device body 201, and the clamping component 3 presses the back surface of the device body 201.

[0097] The solution provided by the embodiment of the present application can clamp the left and right sides of the device body 201 by clamping the two opposite edges of the device body 201 along the first direction X with two support components 1. By clamping the two opposite edges of the device body 201 along the second direction Z with two limiting components 2, the upper and lower sides of the device body 201 can be clamped. By making at least one of the support component 1 and the limiting component 2 abut against the front surface of the device body 201 and making the clamping component 3 press the back surface of the device body 201, the front and back surfaces of the device body 201 can be clamped, and thus the device body 201 can be firmly fixed on the vibration table 102. Moreover, the two support components 1 are arranged on the vibration table 102 in a position-adjustable manner along the first direction X and can move towards or away from each other along the first direction X. The two limiting components 2 are arranged on the support component 1 in a position-adjustable manner along the second direction Z and can move towards or away from each other along the second direction Z. Therefore, the present application can flexibly adjust the distance between the two support components 1 and the distance between the two limiting components 2, so as to be applicable to display devices 200 of different models and different sizes, avoid customizing multiple dedicated test devices for display devices 200 of different models or different sizes of the same model, effectively reduce the test cost, and speed up the test progress. It can be seen that the present application can solve the problem of poor versatility of dedicated test devices in the related art.

[0098] See Figures 2 to 5 , in some embodiments, the vibration table 102 is provided with a plurality of mounting holes 1021, and the plurality of mounting holes 1021 can be arranged in a rectangular array, a circular array or other ways. The size of the mounting holes 1021 and the spacing between adjacent mounting holes 1021 can adopt standard values or can be flexibly customized according to requirements.

[0099] See Figure 6 , the support component 1 includes a bottom plate 11 and a vertical plate 12. The bottom plate 11 is provided with a first strip-shaped hole 111 extending along the first direction X, and the bottom plate 11 is connected to the vibration table 102 through fasteners passing through the first strip-shaped hole 111 and the mounting hole 1021. The vertical plate 12 is fixedly connected to the bottom plate 11, and the side surface of the vertical plate 12 faces the two opposite edges of the device body 201 along the first direction X. In this way, by adjusting the support component 1, the vertical plate 12 can clamp the two opposite edges of the device body 201 along the first direction X, that is, clamp the left and right edges of the device body 201. Among them, the first direction X can be the horizontal direction. The fasteners can adopt bolts and nuts. After loosening the nuts, move the bottom plate 11 and the vertical plate 12 towards or away from each other along the horizontal direction, and the distance between the vertical plates 12 of the two support components 1 can be adjusted to the length dimension of the device body 201 to be tested, and then tighten the nuts to clamp the left and right sides of the device body 201.

[0100] See Figure 3, in some embodiments, the support assembly 1 may further include a gap adjusting rod 15. The gap adjusting rod 15 is disposed between the vertical plate 12 and the edge of the device body 201. For a device body 201 with an overly long or short length dimension, when the fasteners cannot fully fix the device body 201 even when fixed at both ends of the first elongated hole 111, a gap adjusting rod 15 may be provided between the vertical plate 12 and the edge of the device body 201. The gap adjusting rod 15 can fill the gap between the vertical plate 12 and the edge of the device body 201, thereby expanding the adjustment range of the support assembly 1 in the first direction X and further improving the versatility of the testing device 101. The length of the gap adjusting rod 15 may be equal to or slightly greater than the length of the edge of the device body 201. The thickness of the gap adjusting rod 15 can be flexibly processed according to actual needs. The gap adjusting rod 15 can be made of wood, hard rubber, etc.

[0101] In some embodiments, refer to Figure 5 and Figure 6 , the support assembly 1 may further include a connecting plate 14. The connecting plate 14 is connected to the vertical plate 12 and is disposed at an angle (e.g., perpendicularly), and the connecting plate 14 extends along the side of the vertical plate 12 away from the device body 201; the connecting plate 14 is provided with a second elongated hole 141 extending along the second direction Z; correspondingly, refer to Figure 7 and Figure 8 , the limiting assembly 2 may include a limiting plate 22 and a baffle 21; both ends of the limiting plate 22 are provided with first adjustment holes 221, and the limiting plate 22 is connected to the connecting plate 14 through fasteners passing through the first adjustment holes 221 and the second elongated hole 141; the baffle 21 is fixedly connected to the limiting plate 22, and the baffle 21 extends toward the support assembly 1.

[0102] Among them, multiple columns of second elongated holes 141 may be provided on the connecting plate 14. Each column of second elongated holes 141 includes multiple segments of elongated holes. As Figure 6 shown, two columns of second elongated holes 141 are provided on the connecting plate 14, and each column of second elongated holes 141 includes upper and lower segments of elongated holes. Of course, the upper and lower segments of elongated holes can also be connected, and each column of second elongated holes 141 only includes a long segment of elongated hole.

[0103] Refer to Figure 8 , the first adjustment holes 221 on the limiting plate 22 can be elongated holes extending along the first direction X or multiple through holes arranged along the first direction X. When adjusting the positions of the two support assemblies 1 on the vibration table 102 along the first direction X, the first adjustment holes 221 can enable the limiting plate 22 to adaptively adjust its position fixedly connected to the connecting plate 14.

[0104] The baffle 21 and the limit plate 22 can be connected in various ways. In one implementation, when the baffle 21 is a straight plate, it can be fixedly connected to the limit plate 22 by welding or bonding. In another implementation, referring to Figure 8 , when the baffle 21 is an angle steel, one side of the angle steel can be fixedly connected to the limit plate 22 by bolt connection.

[0105] Corresponding to the second strip holes 141 in multiple columns, multiple fasteners can be provided, so as to increase the connection strength between the limit plate 22 and the connection plate 14. The fasteners can be bolts and nuts. Among them, the second direction Z can be the vertical direction. The baffle 21 is fixedly connected to the limit plate 22 extending toward the support assembly 1. After loosening the nut, moving the limit plate 22 and the baffle 21 toward or away from each other in the vertical direction, the distance between the baffles 21 of the two limit assemblies 2 can be adjusted to the width dimension of the device body 201 to be tested, and then tightening the nut can achieve clamping on the upper and lower sides of the device body 201.

[0106] The implementation of at least one of the limit assembly 2 and the support assembly 1 abutting against the front surface of the device body 201 will be described below. In one possible embodiment, referring to Figure 7 and Figure 8 , the limit plate 22 is located on the other side, i.e., the front side, of the support assembly 1 and is connected to the support assembly 1, and the limit plate 22 abuts against the front surface of the device body 201. When the baffle 21 is a straight plate, the limit plate 22 can directly abut against the front surface of the device body 201. Referring to Figure 8 , when the baffle 21 has a bent portion 211 extending in the second direction Z and the bent portion 211 is fixedly connected to the limit plate 22, in other words, when the baffle 21 is an angle steel, the limit plate 22 can indirectly abut against the front surface of the device body 201, that is, one side of the angle steel connected to the limit plate 22, i.e., the bent portion 211, abuts against the front surface of the device body 201. The limit plate 22 located on the front side of the support assembly 1 can abut against the front surface of the device body 201 to block the device body 201, so as to cooperate with the clamping assembly 3 pressing the back surface of the device body 201 to clamp the front and back sides of the device body 201. In order to avoid damaging the display screen of the device body 201, a buffer pad can be provided between the limit plate 22 and the display screen, or between one side of the angle steel connecting the limit plate 22 and the display screen.

[0107] In another possible embodiment, referring to Figure 6 , the support assembly 1 can further include a cover plate 13, the cover plate 13 is connected to the vertical plate 12 and is arranged at an angle, and the cover plate 13 extends along the side of the vertical plate 12 close to the device body 201; the cover plate 13 abuts against the front surface of the device body 201. The included angle between the cover plate 13 and the vertical plate 12 is determined by the included angle between the edge and the front surface of the device body 201. When the edge and the front surface of the device body 201 are vertically arranged, referring toFigure 6 The cover plate 13 is perpendicular to the vertical plate 12. When the edge of the device body 201 forms an acute angle or an obtuse angle with the front, the cover plate 13 and the vertical plate 12 also form a corresponding included angle. Refer to Figure 5 and Figure 6 , two support assemblies 1 are located on the left and right sides of the device body 201. In the support assembly 1 located on the right side of the device body 201, the cover plate 13 extends to the left. In the support assembly 1 located on the left side of the device body 201, the cover plate 13 extends to the right. The extended cover plate 13 is located on the front side of the device body 201 and can abut against the front of the device body 201 to play a blocking role, so as to cooperate with the clamping assembly 3 pressing against the back of the device body 201 to clamp the front and back sides of the device body 201. In order to avoid damaging the display screen of the device body 201, a buffer pad can be provided between the cover plate 13 and the display screen. In addition, it should be noted that when the support assembly 1 includes the cover plate 13, the gap adjusting rod 15 can be arranged at the diagonal corner where the cover plate 13 is connected to the vertical plate 12. In this way, the positioning installation of the gap adjusting rod 15 can be conveniently realized.

[0108] As can be seen from the above, at least one of the support assembly 1 and the limit assembly 2 abuts against the front of the device body 201, and cooperates with the clamping assembly 3 to press against the back of the device body 201 to clamp the front and back of the device body 201.

[0109] Refer to Figure 9 and Figure 10 , the clamping assembly 3 can include two side plates 32, a connecting beam 31 and a support 33. The two side plates 32 are respectively connected to the two vertical plates 12; the connecting beam 31 is connected to one end of the two side plates 32; the support 33 can be adjustably arranged on the connecting beam 31 along the third direction Y to press against the back of the device body 201; wherein, the third direction Y is perpendicular to the first direction X and the second direction Z.

[0110] Among them, as Figure 10 shown, the support 33 can include a pressing block 331 and a first connecting rod 332. One end of the first connecting rod 332 is fixedly provided with the pressing block 331, and the other end is adjustably connected to the connecting beam 31 through two nuts 333 on both sides of the connecting beam 31. By adjusting the distance between the pressing block 331 and the connecting beam 31 along the third direction Y, that is, the front and back direction of the device body 201, the pressing block 331 can be made to press against the back of the device body 201. In order to avoid damaging the device body 201, a buffer pad can be provided on the surface of the pressing block 331.

[0111] Among them, the connecting beam 31 is provided with a third strip-shaped hole 311 extending along the first direction X; the clamping assembly 3 may further include an adjusting screw 34, and the adjusting screw 34 passes through the third strip-shaped hole 311 and is threadedly connected to one end of the side plate 32, so that the side plate 32 can move along the third strip-shaped hole 311. It can be understood that multiple rows of third strip-shaped holes 311 can be provided on the connecting beam 31. Each row of third strip-shaped holes 311 may include multiple segments of strip-shaped holes. As Figure 10 shown, two rows of third strip-shaped holes 311 are provided on the connecting beam 31, and each row of third strip-shaped holes 311 includes six segments of strip-shaped holes. Of course, the six segments of strip-shaped holes can also be communicated, and each row of third strip-shaped holes 311 only includes a long segment of strip-shaped hole. Corresponding to multiple columns of third strip-shaped holes 311, multiple adjusting screws 34 can be provided. As Figure 10 shown, two adjusting screws 34 are provided on the side plate 32 corresponding to two rows of third strip-shaped holes 311. In this way, the connection strength between the side plate 32 and the connecting beam 31 can be increased. When adjusting the positions of the two support assemblies 1 on the vibration table 102 along the first direction X, the third strip-shaped hole 311 can adaptively adjust the position where the connecting beam 31 is fixedly connected to the side plate 32.

[0112] Considering that the back surface of the device body 201 has an inclined surface, see Figure 3 and Figure 10 , in some embodiments, the side plate 32 is rotatably connected to the vertical plate 12; the clamping assembly 3 further includes a locking member 35, and the locking member 35 is connected to the side plate 32 and the vertical plate 12 to limit the relative rotation between the side plate 32 and the vertical plate 12. In this way, according to the inclination degree of the inclined surface on the back surface of the device body 201, the side plate 32 can be rotated by a certain angle relative to the vertical plate 12, so that the pressing block 331 closely fits the back surface of the device body 201 and presses the back surface of the device body 201.

[0113] Among them, the side plate 32 can be rotatably connected to the vertical plate 12 through a pin shaft 36. The locking member 35 can adopt a locking nut, a threaded hole is provided on the vertical plate 12, and an arc-shaped guiding hole 321 is provided on the side plate 32. The screw rod of the locking nut passes through the arc-shaped guiding hole 321 and is threadedly connected to the threaded hole, and the side plate 32 and the vertical plate 12 can be fixedly connected.

[0114] See Figure 4 and Figure 5 , for the display device 200 including the support 202, the testing device 101 may further include a pressing assembly 4, and the pressing assembly 4 can be arranged on the vibration table 102 in a position-adjustable manner along the second direction Z for pressing the support 202. In this way, by providing the pressing assembly 4, the fixing stability of the display device 200 on the vibration table 102 can be further improved.

[0115] See Figure 11, in some embodiments, the pressing assembly 4 may include a cross beam 41, a pressing plate 42 and pressing bolts 43; second adjustment holes 411 are provided at both ends of the cross beam 41, the pressing plate 42 is located on one side of the cross beam 41 and is fixedly connected to the cross beam 41; the screw rods of the pressing bolts 43 pass through the second adjustment holes 411 and are threadedly connected to the bottom plate 11 to apply a pressing force to the pressing plate 42.

[0116] Among them, the bottom plate 11 is provided with threaded holes (not shown in the figure) adapted to the pressing bolts 43, and the screw rods of the pressing bolts 43 can be threadedly connected to the threaded holes. The second adjustment holes 411 on the cross beam 41 may be elongated holes extending along the first direction X, or may be a plurality of through holes arranged along the first direction X. When adjusting the positions of the two support assemblies 1 on the vibration table 102 along the first direction X, the second adjustment holes 411 can enable the cross beam 41 to adaptively adjust its position fixedly connected to the pressing bolts 43. And, the pressing plate 42 can be directly connected to the cross beam 41, or indirectly connected to the cross beam 41 through an intermediate connecting member. As Figure 11 shown, the pressing plate 42 can be connected to the cross beam 41 through a second connecting rod 44. Two nuts can be threadedly connected to the second connecting rod 44, and the two nuts are located on both sides of the cross beam 41 to fix the second connecting rod 44 to the cross beam 41. It can be understood that by adjusting the two nuts, the distance between the pressing plate 42 and the cross beam 41 can be set along the second direction Z as needed, so that the pressing assembly 4 is applicable to supports 202 of different heights, effectively improving the versatility of the pressing assembly 4.
