[0002] After the film material is produced, it is necessary to conduct anti-collision tests on its anti-scratch properties. The traditional anti-collision test is to set up a telescopic mechanism to impact the film material, and then observe whether there are any marks on the surface of the film. However, this method cannot effectively simulate scratches on the film material, and the test effect is poor. Therefore, there is an urgent need for a device that can better perform anti-collision tests on the film. Utility Model Content

[0003] The utility model aims to provide a film anti-collision testing device to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve the technical problem is:

[0005] A film anti-collision testing device comprises: a base; a fixed plate connected to the base; a test unit, comprising a rotating drive member, a rotating rod and a connecting member, wherein the rotating drive member is connected to the base, the rotating drive member drives and connects the rotating rod, a plurality of connecting members are connected to the rotating rod, and a plurality of connecting members are respectively hooked with collision blocks, and the rotating drive member can drive the rotating rod to rotate and cause a plurality of the collision blocks to collide with the fixed plate.

[0006] This technical solution has at least the following beneficial effects: the film to be tested is fixed on the fixed plate so that the film to be tested is opposite to the rotating rod, and then the test can be carried out. The rotating rod is driven to rotate by the rotating driving member, and the rotating rod can drive multiple impact blocks to rotate around the rotating rod through multiple connecting members, and the impact blocks will collide with the fixed plate when rotating and passing through the fixed plate. Since the impact blocks are hooked on the connecting members, the impact blocks can swing flexibly on the connecting members. After the impact blocks collide with the fixed plate, the impact blocks can adjust their position state along the surface of the fixed plate, so that the impact blocks scratch the membrane material, thereby better simulating the active state when foreign objects collide with the membrane material, thereby improving the accuracy of the membrane material anti-collision test and being more practical.

[0007] As a further improvement of the above technical solution, the connecting member is a spring, one end of which is connected to the fixed plate, and the collision block is hooked on the other end of the spring. When the rotating rod drives the collision block to rotate, the centrifugal force of the collision block elastically stretches the spring, and when the collision block rotates to hit the fixed plate, the collision block is pushed by the fixed plate, so that the spring part connected to it elastically retracts, and at this time, a retreat space can be provided for the collision block, so that the collision block can be better simulated under the condition of a large impact force colliding with the fixed plate, thereby improving the test effect of the collision block.

[0008] As a further improvement of the above technical solution, the rotating driving member is a driving motor, which provides a rotating driving force to the rotating rod, thereby driving the plurality of collision blocks to rotate around the rotating rod, and the rotating speed of the rotating rod can be controlled by the driving motor to adjust the collision force when the collision blocks collide with the fixed plate.

[0009] As a further improvement of the above technical solution, a mounting groove is provided on the top side of the base, the rotating drive member is located in the mounting groove, a panel is connected to the top side of the base, the output end of the rotating drive member passes through the panel upward, a connector is inserted through the panel and connected to the rotating drive member.

[0010] As a further improvement of the above technical solution, a cover plate is connected to the top side of the panel, and the output end of the rotary drive member passes through the cover plate upward. The cover plate can shield the top side of the panel, reduce the exposure of the connecting parts and other structures, and further improve the overall appearance.

[0011] As a further improvement of the above technical solution, a slot is provided on the top side of the panel, and the bottom side of the fixing plate is inserted into the slot. The fixing plate can be installed and removed from the panel. When the film material to be tested needs to be fixed on the fixing plate, the fixing plate is first pulled out of the slot. At this time, the film material can be conveniently fixed on the fixing plate by bonding or clamping. After completion, the bottom side of the fixing plate can be inserted into the slot, and the panel can be quickly installed and removed.

[0012] As a further improvement of the above technical solution, a light strip is connected to the top side of the panel. When the film material needs to be subjected to an anti-collision test, the light strip can be turned on to observe the film material being scratched by the impact through the light strip, thereby improving the test experience.

[0013] As a further improvement of the above technical solution, the utility model further includes a transparent box connected to the top side of the panel, the transparent box cover is arranged on the outside of the fixed plate and the test unit, the top side of the transparent box is provided with an avoidance hole, and the fixed plate extends upward from the avoidance hole.

[0025] Reference Figure 1 , Figure 2 A film anti-collision test device includes a base 100, a fixing plate 200 and a test unit, wherein the fixing plate 200 is connected to the base 100; the test unit includes a rotary drive member 310, a rotating rod 320 and a connecting member 330, wherein the rotary drive member 310 is connected to the base 100, the rotary drive member 310 drives and connects the rotating rod 320, the rotating axis of the rotating rod 320 extends in the up-down direction, the rotating rod 320 is connected to a plurality of connecting members 330, and a plurality of connecting members 330 are respectively hooked with collision blocks 340, the rotary drive member 310 can drive the rotating rod 320 to rotate and make the plurality of collision blocks 340 collide with the fixing plate 200 In actual application, the two sides of the rotating rod 320 can be connected with multiple connecting members 330 at intervals along the up and down directions, and the rotating rods 320 on both sides are staggered in the up and down directions, thereby improving the coverage of the impact test of the impact block 340 on the film material. As for the connection between the impact block 340 and the connecting member 330, a hook can be connected to the impact block 340 and connected to the connecting member 330 through the hook, or a connecting ring is formed on the connecting member 330, and a connecting ring is also connected to the impact block 340. The two connecting rings are buckled with each other, so that the impact block 340 is hooked on the connecting member 330. Since the impact block 340 is hooked and connected, the impact block 340 has greater freedom of movement.

[0026] As can be seen from the above, the film to be tested is fixed on the fixed plate 200 so that the film to be tested is opposite to the rotating rod 320, and then the test can be carried out. The rotating driving member 310 drives the rotating rod 320 to rotate, and the rotating rod 320 can drive multiple collision blocks 340 to rotate around the rotating rod 320 through multiple connecting members 330. When the collision blocks 340 rotate and pass through the fixed plate 200, they will collide with the fixed plate 200. Since the collision blocks 340 are hooked on the connecting members 330, the collision blocks 340 can swing flexibly on the connecting members 330. After the collision blocks 340 collide with the fixed plate 200, the collision blocks 340 can adjust their position state along the surface of the fixed plate 200, so that the collision blocks 340 slide across the film material, thereby better simulating the active state when foreign objects collide with the film material, thereby improving the accuracy of the anti-collision test of the film material and making it more practical.

[0027] The connecting member 330 is used to connect the spring and the rotating rod 320 to extend the length of the connecting member 330 rotating around the rotating rod 320. The connecting member 330 can be a strip structure or a rope. In the present embodiment, the connecting member 330 is a spring, one end of which is connected to the fixing plate 200, and the impact block 340 is hooked on the other end of the spring. In practical applications, a hole can be opened on the rotating rod 320, one end of the spring can be bent into a hook structure to be hooked on the opening, and the other end of the spring can be bent into a ring structure to be hooked with the impact block 340. When the rotating rod 320 drives the impact block 340 to rotate, the centrifugal force of the impact block 340 stretches the spring elasticity. When the impact block 340 rotates to hit the fixed plate 200, the impact block 340 is pushed by the fixed plate 200, so that the spring part connected to it elastically shrinks. At this time, the impact block 340 can be provided with retreat space, which can better simulate the situation where the impact block 340 collides with the fixed plate 200 under a large impact force, thereby improving the test effect of the impact block 340.

[0028] The rotating drive member 310 is mainly used to provide a driving force for rotation. There are many structural forms, for example, it can be a rotating cylinder. In order to more flexibly control the rotation speed of the rotating rod 320, in this embodiment, the rotating drive member 310 is a driving motor. The driving motor provides a driving force for rotation to the rotating rod 320, thereby driving the plurality of collision blocks 340 to rotate around the rotating rod 320, and the rotation speed of the rotating rod 320 can be controlled by the driving motor to adjust the impact force when the collision block 340 collides with the fixed plate 200. In actual applications, a knob for controlling the rotation speed of the driving motor can also be provided on the base 100, so as to facilitate the adjustment of the rotation speed of the collision block 340.

[0029] In order to reduce the overall volume, a structure for accommodating the mounting groove 110 can be opened on the base 100. Specifically, the top side of the base 100 is provided with a mounting groove 110, and the rotating drive member 310 is located in the mounting groove 110. The top side of the base 100 is connected to a panel 120, and the output end of the rotating drive member 310 passes through the panel 120 upward, and a connecting member 330 is inserted into the panel 120 and connected to the rotating drive member 310. In actual applications, electrical components such as circuit boards can also be installed in the mounting groove 110 to make the overall structure more compact, and a boss can be formed upward at the position of the panel 120 facing the rotating drive member 310, so that a slot that is compatible with the rotating drive member 310 can be opened at the position of the panel 120 facing the rotating drive member 310 to better limit the rotating drive member 310. In addition, the panel 120 can be positioned on the top side of the base 100 by means of a buckle and a slot that cooperate with each other. The base 100 is provided with an installation groove 110 to accommodate the rotating drive member 310 and facilitate the initial installation and fixation of the rotating drive member 310. Then the panel 120 is installed on the top side of the base 100, and the top side of the base 100 is covered and closed to improve the overall appearance. The connecting member 330 is driven into the panel 120 to connect to the rotating drive member 310, and the panel 120 and the rotating drive member 310 are further installed and fixed, and the overall structure is more compact and stable.

[0030] Furthermore, the top side of the panel 120 is connected with a cover plate 130, and the output end of the rotary drive member 310 passes upward through the cover plate 130. The cover plate 130 can shield the top side of the panel 120, reduce the exposure of the connecting member 330 and other structures, and further improve the overall appearance.

[0031] In the above embodiment, the fixing plate 200 can be directly fixedly connected to the base 100 or the panel 120. When the film needs to be fixed or replaced, it is necessary to fix it on the fixing plate 200. In order to improve the convenience of operation, in this embodiment, a slot 121 is provided on the top side of the panel 120, and the bottom side of the fixing plate 200 is inserted into the slot 121. In order to improve the stability of the connection, the bottom side of the panel 120 and the slot 121 can be further positioned by snaps, or they can be connected by interference fit. The fixing plate 200 can be assembled and disassembled from the panel 120. When the film material to be tested needs to be fixed to the fixing plate 200, the fixing plate 200 is first pulled out of the slot 121. At this time, the film material can be conveniently fixed to the fixing plate 200 by bonding or clamping. After completion, the bottom side of the fixing plate 200 can be inserted into the slot 121, and the panel 120 can be quickly assembled and disassembled.

[0032] In some embodiments, a light strip 122 is connected to the top side of the panel 120, and the light strip 122 can be arranged around the outside of the rotating rod 320 and the fixing plate 200, so as to improve the brightness of the light irradiated to the film material. When the film material needs to be subjected to an anti-collision test, the light strip 122 can be turned on to observe the film material being scratched by the impact through the light strip 122, thereby improving the test experience.

[0033] The collision block 340 is driven by the rotating rod 320 to continuously collide with the fixed plate 200, which may cause the risk of falling. Figure 3 As shown, the utility model further includes a transparent box 400 connected to the top side of the panel 120, the transparent box 400 is covered on the outside of the fixed plate 200 and the test unit, and a avoidance hole is provided on the top side of the transparent box 400, and the fixed plate 200 extends upward from the avoidance hole. The transparent box 400 can surround and protect the part of the space where the collision block 340 collides with the film material, and retain the avoidance box of the transparent box 400 extending upward from the top of the fixed plate 200, so as to facilitate the direct extraction of the fixed plate 200 from the transparent box 400 to achieve the replacement of the film material. During the test, the situation of the film material anti-collision test can be directly observed through the transparent box 400, so as to improve the safety during the test. In addition, the avoidance hole can also play a limiting role on the top of the fixed plate 200, which can further improve the stability of the fixed plate 200 and reduce its shaking during the collision with the collision block 340.

[0034] In some embodiments, the transparent box 400 is detachably connected to the panel 120. For example, a positioning groove is provided on the panel 120. When the transparent box 400 is installed, the bottom side of the transparent box 400 can be inserted into the positioning groove for positioning. The transparent box 400 can also be directly removed from the panel 120, so as to facilitate the replacement and maintenance of the collision block 340 and other structures, and improve the convenience of operation and use.

[0035] In the above embodiment, the number of the test unit may be only one, in which case only a single film material can be directly subjected to the anti-collision test, and in order to improve the intuitiveness of the test comparison, in this embodiment, at least two, for example, two, of the test units are arranged at intervals, and the sides of the two test units are correspondingly provided with the fixing plates 200.
