[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 to 6 , in the embodiment of the present invention, a glass cover plate drop test device includes a lifting mechanism 10, a rotating bracket 20, and a cleaning assembly 40. At the bottom end of the lifting mechanism 10, a test box 12 with a discharge port 11 opened at one side bottom is fixedly installed. The lifting mechanism 10 is connected through a support rod 14 to a test fixture 13 located directly above the test box 12. The bottom end of the rotating bracket 20 rotatably installed on the lifting mechanism 10 is located inside the test box 12. Inside the rotating bracket 20, three groups of test floors 15 arranged equidistantly in a semi-circular shape around the rotating rod 204 included in the rotating bracket 20 are detachably installed. Inside the test box 12, a driving mechanism 30 for controlling the flipping of the rotating bracket 20 is rotatably installed. A group of cleaning assemblies 40 are provided between adjacent two groups of test floors 15. An elastic component 50 for controlling the radial displacement of both ends of the cleaning assembly 40 along the rotating bracket 20 is installed between the lifting mechanism 10 and the test box 12.

[0036] Components such as the equipment box that control the drop test device are all prior arts and will not be elaborated here. When the glass cover plate drop test device is in use, the glass cover plate to be tested is installed on the test fixture 13. The test fixture 13 can adopt the common electric fixture type in the prior art. After the assembled glass cover plate to be tested is completed, the lifting mechanism 10 is started to adjust it to the corresponding height. Then, the test fixture 13 is started to make the glass cover plate fall downward. The falling glass cover plate hits the corresponding test floor 15, and the test process of the glass cover plate can be realized. The top of the test box 12 is higher than the top surface of the bottommost test floor 15 by a certain height, which is also beneficial to avoiding the splashing of debris generated during the drop test everywhere.

[0037] When the test of a single glass cover plate is completed or the floor material for testing needs to be replaced, the driving mechanism 30 is started to drive the rotating bracket 20 to rotate. The rotating bracket 20 drives the multiple groups of test floors 15 installed inside it to rotate. The rotating bracket 20 conveniently rotates the test floors 15 made of different materials one by one to directly below the test fixture 13, improving the flexibility of the actual use of the glass cover plate drop test device and the efficiency of batch drop testing of glass cover plates. Moreover, the rotation of the test floor 15 with glass debris piled up on its surface can conveniently pour the glass debris into the interior of the test box 12, facilitating the centralized treatment of the garbage after the test. And during the rotation of the test floor 15, its top surface can always abut against the cleaning component 40 supported by the elastic component 50. The rotation of the test floor 15 in contact with the cleaning component 40 can achieve the efficient cleaning of the debris on its surface, avoiding the unevenness of its surface during the use of the test floor 15, which is beneficial to improving the accuracy of the actual test of the device.

[0038] Refer to Figures 1 to 4 Specifically, the lifting mechanism 10 includes a support frame 101 fixedly connected to the test box 12. Two groups of symmetric lifting screws 102 are rotatably installed inside the support frame 101. Two groups of first motors 103 with output ends connected to the top ends of the lifting screws 102 are fixedly installed at the top of the support frame 101. A plurality of auxiliary rods 104 located on both sides of the lifting screws 102 are welded inside the support frame 101. Both groups of lifting screws 102 are threadedly connected to the rod 14, and the plurality of auxiliary rods 104 and the rod 14 are slidably connected. When the two groups of first motors 103 are started synchronously, the first motors 103 drive the lifting screws 102 connected thereto to rotate. The two groups of lifting screws 102 can drive the rod 14 to slide up and down on the surface of the auxiliary rods 104, and the rod 14 drives the test fixture 13 and its connected components, etc. to be adjusted up and down.

[0039] In one embodiment, refer to Figures 1 to 5Specifically, the rotating bracket 20 includes two groups of half gear rings 201 connected to the driving mechanism 30, the tops of the two groups of half gear rings 201 are welded with connecting rods 202, the bottoms of the connecting rods 202 are welded with support plates 203 close to the inner side of the support frame 101, the support plates 203 are rotatably connected to the support frame 101 through welded rotating rods 204, and the ends of the rotating rods 204 can be rotatably connected to the support frame 101 through bearings, multiple groups of cross bars 205 are welded between the two groups of half gear rings 201, the cross bars 205 are connected to multiple groups of mounting bases 207 supporting the test floors 15 through welded vertical bars 206, the cross bars 205, the vertical bars 206 and the mounting bases 207 provide installation space for fixing different test floors 15, the test floors 15 can be fixedly connected to the mounting bases 207 through bolts and other components, and the test floors 15 can be made of concrete push plates, steel plates, latex plates, etc. according to the actual needs of customers.

[0040] Correspondingly, the driving mechanism 30 includes two groups of rotating shafts 301 rotatably installed inside the test box 12, and two groups of gears 302 meshing with the half gears 302 are welded on the two groups of rotating shafts 301. One end of the two groups of rotating shafts 301 extending to the outside of the test box 12 is connected to a control component 303, wherein the control component 303 includes a fixed bracket 3031 fixedly installed on the outside of the test box 12, and a second motor 3032 is detachably installed on the top of the fixed bracket 3031, and the output end of the second motor 3032 is fixedly connected to the end of one of the groups of rotating shafts 301. The surfaces of the two groups of rotating shafts 301 extending to the outside of the test box 12 are welded with sprockets 3033, and the two groups of sprockets 3033 are connected through a chain 3034.

[0041] Start the second motor 3032, and the second motor 3032 drives the rotating shaft 301 connected thereto to rotate. The above-mentioned rotating shaft 301 drives another set of rotating shafts 301 to rotate through the sprocket 3033 and the chain 3034. The gears 302 on the two sets of rotating shafts 301 rotate synchronously in the same direction. The gear 302 can drive the half gear ring 201 and its connecting structure to rotate. The half gear ring 201 drives the connecting rod 202 and the support plate 203 to rotate on the inner side of the support frame 101, which can ensure the stable rotation adjustment of the rotating bracket 20. The rotating shaft 301 and the test box 12 can also be rotatably connected by bearings and other components. The welding connection method between the components can also be selected according to the actual use of the device. Bolt-fixed connection or other connection methods can be used.

[0042] Based on the above embodiments, see Figures 1 to 4 or Figure 6, Specifically, the cleaning component 40 includes a support roller 401 erected between two adjacent groups of test floors 15. Both ends of the support roller 401 are connected to an elastic component 50. A cleaning part 402 is fixedly installed on the outer surface of the support roller 401. The test floor 15 rotates in contact with the surface of the cleaning part 402. The cleaning part 402 can efficiently clean the surface of the test floor 15. Among them, the cleaning part 402 is a sponge brush or a soft brush fixedly installed on the support roller 401. Both the sponge brush and the soft brush can efficiently handle glass debris and the like on the test floor 15.

[0043] Correspondingly, the elastic component 50 includes a diagonal strut 501 connecting the support frame 101 and the test box 12. The assembly between the diagonal strut 501 and the components can all adopt welding and other methods. A sliding rod 502 that penetrates through the end of the support roller 401 is fixedly installed inside the diagonal strut 501. A spring 503 sleeved on the outer circle of the sliding rod 502 is installed between the end of the support roller 401 and the inner wall of the diagonal strut 501. When the test floor 15 rotates in contact with the cleaning part 402, the test floor 15 can push the support roller 401 to slide up and down on the surface of the sliding rod 502 through the cleaning part 402. The end of the support roller 401 can drive the spring 503 to stretch and contract. The spring 503 provides corresponding elastic support for the support roller 401 and the cleaning part 402, which can conveniently make the cleaning part 402 firmly fit the test floor 15. During the rotation of the rotating bracket 20, the cleaning part 402 is used to automatically clean the surface of the test floor 15, further improving the convenience of the actual use of the glass cover dropping test device.

[0044] Furthermore, two groups of symmetric annular bridge frames 16 are welded to the inner circle of each group of semi-tooth rings 201. The outer circle of the annular bridge frame 16 abuts against the end of the support roller 401 located between two adjacent test floors 15. When the rotating bracket 20 rotates to the position where the support roller 401 is located at the gap between two adjacent test floors 15, the end of the support roller 401 is slidably erected on the annular bridge frame 16, which can improve the smoothness of the movement of the support roller 401 following the rotation of the rotating bracket 20. And the provision of the annular bridge frame 16 is also beneficial to expanding the distance between adjacent test floors 15 during the actual application of the device. The increase in the distance between adjacent test floors 15 is also convenient for pouring the debris generated by the test.

[0045] An inclined guide plate 17 is fixedly installed inside the test box 12. The bottom end of the inclined guide plate 17 extends to the discharge port 11 of the test box 12. The test debris poured from the test floor 15 can fall onto the inclined guide plate 17. The debris on the inclined guide plate 17 can be conveniently conveyed directly to the outside of the device from the discharge port 11. A collection basket or other device can be placed at the discharge port 11 on one side of the device to hold the garbage generated by the test.
