As shown in fig. 1 to 5, in some embodiments of the present application, a ball drop test device for testing impact resistance of glass includes: a glass fixing assembly 10 and a test ball fixing assembly. The glass fixing assembly 10 includes a housing structure 11, a moving structure 12, and a glass fixing structure 13, the moving structure 12 being movably disposed within the housing structure 11, the glass fixing structure 13 being fixed to the moving structure 12. The test ball attachment assembly includes a support structure and a test ball attachment structure 22, the test ball attachment structure 22 having a test ball mounting portion.

By applying the technical scheme of the embodiment, the glass fixing structure 13 is arranged on the moving structure 12, the glass fixing structure 13 can be moved by moving the moving structure 12, the glass fixing structure 13 can be moved to adapt to different glass for test, and thus, the glass adapting to different glass can be realized by moving the moving structure 12 without changing the falling ball testing device. The technical scheme of the embodiment effectively solves the problem that the falling ball testing device needs to be replaced according to different sizes of test glass when falling ball tests in the prior art are carried out.

As shown in fig. 1 to 4, in some embodiments, a side of the moving structure 12 facing the bottom surface of the housing structure 11 has a first detent portion, and a side of the housing structure 11 facing the moving structure 12 has a second detent portion, where the first detent portion and the second detent portion are engaged in a mating manner. The movable structure 12 and the shell structure 11 are conveniently fixed by the clamping of the first clamping part and the second clamping part. When the moving structure 12 moves to a predetermined position, the moving structure 12 engages with the housing structure 11, so that the moving structure 12 and the housing structure 11 are fixed.

As shown in fig. 1 and 4, in some embodiments, the moving structure 12 includes a first slide bar 121, a second slide bar 122, a third slide bar 123, and a fourth slide bar 124, the first slide bar 121 being slidably connected to the second slide bar 122, the second slide bar 122 being slidably connected to the third slide bar 123, the third slide bar 123 being slidably connected to the fourth slide bar 124, the fourth slide bar 124 being slidably connected to the first slide bar 121. The structure is convenient to set and adjust. The ends of the first 121, second 122, third 123 and fourth 124 slide bars each protrude from the housing structure 11, which may facilitate adjustment of the first 121, second 122, third 123 and fourth 124 slide bars. The sliding blocks and the sliding rail structures on the first sliding rod 121, the second sliding rod 122, the third sliding rod 123 and the fourth sliding rod 124 are not described in detail herein by the mutual matching of the first sliding rod 121, the second sliding rod 122, the third sliding rod 123 and the fourth sliding rod 124.

As shown in fig. 2 and 4, in some embodiments, the first latching portion is a latch 14, and sides of the first slide bar 121, the second slide bar 122, the third slide bar 123 and the fourth slide bar 124 facing the bottom surface of the housing structure 11 each have the latch 14, and the second latching portion is an array of latch grooves 111. The array-shaped clamping grooves 111 enable the matching positions of the clamping teeth 14 to be more, for example, the clamping fixation can be realized when the first sliding rod 121, the second sliding rod 122, the third sliding rod 123 and the fourth sliding rod 124 move a little, and the linear movement of the first sliding rod 121, the second sliding rod 122, the third sliding rod 123 and the fourth sliding rod 124 is approximately realized. Before the movement of the moving structure 12 is adjusted, the moving structure 12 may be moved upward entirely, so that the latch 14 and the slot 111 are disengaged, and the moving structure 12 is moved.

As shown in fig. 4, in some embodiments, the cross-sectional area of the tooth root of the latch 14 in the direction of the tooth tip of the latch 14 gradually decreases, and the outer surface of the tooth root of the latch 14 in the direction of the tooth tip of the latch 14 is an inclined surface. The cross-sectional area from the tooth root of the latch 14 to the tooth tip of the latch 14 is gradually reduced, so that the tooth tip of the latch 14 forms a guide, is easily matched with the latch groove 111, and is inserted into the latch groove 111.

As shown in fig. 1 and 4, in some embodiments, the latch 14 is made of a rubber material or a plastic material. Thus, a certain buffer effect is provided between the latch 14 and the latch groove 111. The above-described structure makes it possible to achieve movement of the moving structure 12 relative to the housing structure 11 even if the moving structure 12 is not lifted upward.

As shown in fig. 5, in some embodiments, the test ball attachment structure 22 includes a moving portion that is mounted on the support structure and the test ball mounting portion is secured to the moving portion. The position of the test ball fixing part (test ball mounting part) can be adjusted by the arrangement of the moving part, and the test ball fixing part drives the test ball to move, so that the alignment between the test ball fixing structure 22 and the glass fixing structure 13 is realized. The structure makes the universality of the embodiment stronger and the implementation easier.

As shown in fig. 5, in some embodiments, the moving part includes a first motor, a first screw, and a first moving block, where the first motor is fixed on the support structure, an output end of the first motor is connected to the first screw, the first moving block has a first internal threaded hole adapted to the first screw, and the first screw is threaded in the first internal threaded hole. The structure realizes automatic adjustment of the position of the test ball, for example, the first motor is started to drive the first screw rod to rotate, and the translation of the first moving block is realized through the rotation of the first screw rod.

As shown in fig. 5, in some embodiments, the moving part further includes a second motor, a second screw, and a second moving block, an output end of the second motor is connected to the second screw, the second screw is rotatably disposed on the supporting structure 21, the second moving block has a second internal threaded hole adapted to the second screw, the second screw is disposed in the second threaded hole in a penetrating manner, and the test ball mounting part is disposed on the second moving block. The second motor, the second lead screw and the second moving block increase the freedom degree of movement of the test ball, namely the test ball can move on the whole plane. Thus, the centering range of the test ball is wider before the test ball is free-falling.

In some embodiments, as shown in fig. 5, the support structure includes a slide rail, and the second motor has a slider that mates with the slide rail, the slider being disposed on the slide rail. When the first motor rotates to drive the first moving block to move, the first moving block drives the second motor to move, and the friction force between the second motor and the supporting structure is greatly reduced through the cooperation of the sliding block and the sliding rail, so that the abrasion is reduced, and the moving precision is improved.

It should be noted that, as shown in fig. 2, the first screw and the second screw in this embodiment are two, so that the movement of the test ball is smoother and the precision is higher. The two first lead screws and the two second lead screws support the test ball together, so that the deflection deformation is smaller.

The application still includes control assembly, and control assembly includes control module and detection module, and experimental ball fixed subassembly and detection module all are connected with the control module electricity, and detection module sets up on fixed knot constructs (experimental ball fixed knot constructs 22), and detection module detects glass fixed knot constructs 13 and fixed knot constructs's relative position to transmit to control module, control module control glass fixed knot constructs 13 and experimental ball fixed knot constructs's relative position. The control module controls the relative positions of the glass fixing structure 13 and the fixing structure according to the detection result of the detection module, and controls the mutual movement between the glass fixing structure 13 and the fixing structure. When the relative position of the glass fixing structure 13 and the fixing structure is the preset position, the glass fixing structure 13 and the fixing structure are not moved relatively any more, and the ball falling test can be performed. The structure ensures that the ball falling test adjustment efficiency is higher and the alignment accuracy is better.
