[0001] The utility model relates to the technical field of touch screen testing, in particular to an impact resistance testing device for a touch screen. Background Art

[0002] Touch screens, as sensors, are increasingly used in various industries, including life and manufacturing. Currently, touch screens used in the market are roughly divided into two categories: resistive touch screens and capacitive touch screens. Impact resistance testing of touch screens is a crucial test to ensure they continue to function properly even after accidental impacts or drops.

[0004] Based on the above technical features, the problem that arises is that in the existing technology, only the impact force perpendicular to the touch screen can be tested. However, the use environment of the touch screen is complex, so the external force applied to the touch screen is not fixed. Therefore, the test results of the device cannot be applied to the complex use environment of the touch screen, and the accuracy of the test results is poor.

[0005] Therefore, it is necessary to solve the above problems through the impact test equipment of the touch screen. Utility Model Content

[0006] The purpose of the present invention is to provide an impact resistance testing device for a touch screen, so as to solve the problems raised in the above background technology.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] The utility model provides Figures 1 to 3 The impact test equipment for a touch screen shown in the figure includes a test table 1. The test table 1 is placed horizontally and has a placement groove carved on the top. A touch screen 7 is placed in the placement groove. The placement groove is sized to match the touch screen 7 to limit the movement of the touch screen 7.

[0020] A hollowed-out groove is carved into the test bench 1, located below the touch screen 7 and connected to the placement groove. A storage groove is carved into the test bench 1, connected to the hollowed-out groove and slidably engaged with a horizontally arranged support plate 8. The support plate 8 slides over the storage groove and makes sliding contact with the bottom of the touch screen 7, providing support for the touch screen 7.

[0021] An inverted T-shaped limit slot is chiseled into the test bench 1. A matching bracket 6 with an inverted T-shaped bottom slides within the limit slot. Bracket 6 extends vertically upward beyond the limit slot and features a horizontal connecting rod integrally formed at its top. An impact handle 2 is pivotally connected to the connecting rod. The end of the impact handle 2, distal from the connection with the connecting rod, is fixedly mounted with an impact head. The impact head contacts the touch screen 7, impacting the touch screen 7.

[0022] An adjustment disc 3 is welded to the connecting rod of the bracket 6. Multiple adjustment holes 4 are drilled horizontally through the adjustment disc 3. These holes 4 are at varying heights and evenly distributed along the rotational circumference of the impact handle 2. A stopper hole is drilled horizontally through the impact handle 2. A pin 5 is inserted into the stopper hole and engages with the adjustment hole 4 to limit the impact handle 2.

[0023] Working Principle: During use, according to the test height, the impact handle 2 is rotated to the adjustment hole 4 corresponding to the test height. At this time, the limit hole on the impact handle 2 is aligned with and connected to the adjustment hole 4. Then, the pin 5 is inserted through the limit hole and into the adjustment hole 4 to complete the position limit of the impact handle 2.

[0024] Afterwards, the touch screen 7 to be tested is placed in the placement groove. At the same time, the support plate 8 is pushed to slide and cover the hollow groove. At this time, the top of the support plate 8 contacts the bottom of the touch screen 7 and forms a support for the touch screen 7.

[0025] Then, the bracket 6 is pushed, and it slides along the limiting groove. During this process, the connecting rod of the bracket 6 drives the adjustment plate 3 and the impact handle 2 to move synchronously. When the impact head of the impact handle 2 moves to the point where the impact head lands and the detection position on the touch screen 7, the pushing of the bracket 6 stops.

[0026] Then, the latch 5 is removed from the adjustment hole 4 into which it is inserted. At this point, the impact handle 2 is released from its restraint position. Thereafter, under the influence of gravity, the impact head of the impact handle 2 rotates and falls, eventually contacting the touch screen 7. During this contact, the touch screen 7 is subjected to a diagonally downward force, one component of which is perpendicular to the touch screen 7, and the other component is parallel to the touch screen 7. This diverse force direction greatly adapts to the complex operating environments of the touch screen 7.

[0027] If it is necessary to test the impact resistance of the touch screen 7 in the hollowed-out state, the support plate 8 only needs to be pulled out.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
