[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1 to Figure 6 In an embodiment of the present invention, a glass cover drop test device includes a lifting mechanism 10, a rotating bracket 20 and a cleaning assembly 40. A test box 12 with a discharge port 11 at the bottom of one side is fixedly installed at the bottom of the lifting mechanism 10. The lifting mechanism 10 is connected to a test fixture 13 located directly above the test box 12 through a rack rod 14. The bottom end of the rotating bracket 20 rotatably installed on the lifting mechanism 10 is located in the test box 12. Three groups of test floors 15 equidistantly arranged in a semicircle around a rotating axis 301 are detachably installed in the rotating bracket 20. A driving mechanism 30 for controlling the flipping of the rotating bracket 20 is rotatably installed in the test box 12. A group of cleaning assemblies 40 are arranged between two adjacent groups of test floors 15. An elastic assembly 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.

[0022] The equipment box and other components of the control drop test device are all prior art and will not be elaborated on here. When the glass cover drop test device is in use, the glass cover 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 glass cover to be tested is assembled, the lifting mechanism 10 is started to adjust it to the corresponding height. The test fixture 13 is started to make the glass cover fall downward, and the falling glass cover falls on the corresponding test floor 15. In this way, during the test of the glass cover, the top of the test box 12 is higher than the top surface of the bottom test floor 15 by a certain height, which is also conducive to avoiding the debris generated during the drop test from splashing everywhere.

[0023] When the test of a single glass cover is completed or the material of the tested floor needs to be changed, the driving mechanism 30 is started to drive the rotating bracket 20 to rotate, and the rotating bracket 20 drives the multiple groups of test floors 15 installed therein to rotate. The rotating bracket 20 is convenient for rotating the test floors 15 of different materials one by one to directly under the test fixture 13, thereby improving the flexibility of the actual use of the glass cover drop test device and the efficiency of batch glass cover drop tests. The rotation of the test floor 15 with glass debris accumulated on the surface can facilitate the dumping of the glass debris into the interior of the test box 12, which is convenient for centralized treatment of garbage after the test. During the rotation of the test floor 15, its top surface can always be in contact with 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 efficient cleaning of the debris on its surface, avoid the uneven surface of the test floor 15 when it is in use, and is conducive to improving the accuracy of the actual test of the device.

[0026] 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.

[0027] 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.

[0028] Based on the above embodiments, see Figure 1 to Figure 4 or Figure 6Specifically, the cleaning component 40 includes a supporting roller 401 mounted between two adjacent groups of test floors 15, both ends of the supporting roller 401 are connected to the elastic component 50, a cleaning portion 402 is fixedly installed on the outer surface of the supporting roller 401, and the test floor 15 rotates in contact with the surface of the cleaning portion 402, and the cleaning portion 402 can efficiently clean the surface of the test floor 15, wherein the cleaning portion 402 is a sponge brush or a soft brush fixedly mounted on the supporting roller 401, and the sponge brush or the soft brush can efficiently handle glass fragments and the like on the test floor 15.

[0029] Correspondingly, the elastic component 50 includes an inclined support rod 501 connecting the support frame 101 and the test box 12. The assembly between the inclined support rod 501 and the components can be carried out by welding or the like.

The end of the support roller 401 can drive the spring 503 to expand and contract. The spring 503 provides corresponding elastic support for the support roller 401 and the cleaning part 402, which can facilitate the cleaning part 402 to be firmly attached to the test floor 15. The rotating bracket 20 uses the cleaning part 402 to automatically clean the surface of the test floor 15 during the rotation process, thereby further improving the convenience of actual use of the glass cover drop test device.
