Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
Set up the device of the intensity of test touch screen based on energy conservation, the intensity of touch-screen is tested.
The embodiment of the invention provides a kind of device of intensity of test touch screen, as shown in Figure 1, comprising:
Containing component is used for holding touch-screen to be measured;
Elastomeric element, one end is fixed, and the other end is connected with containing component, for generation of acting on the described accommodation section part and continuing to the elastic force of test position from initial position, drive described touch-screen motion by containing component, touch-screen is impacted at the test position place.
Use the technology that the embodiment of the invention provides, elastomeric element promotes touch-screen from initial position to test position, because the stroke of elastomeric element between initial position and test position is positioned at the impulse stroke of elastomeric element, therefore can guarantee all to be consistent and to meet test condition for the each time strength test of touch-screen, eliminate the uncertainty in the standardized test process.
As shown in Figure 1, impact member has most advanced and sophisticated teat.
In a preferred embodiment, elastomeric element is in vertical laying state.
In a preferred embodiment, as shown in Figure 2, elastomeric element is in the horizontal positioned state.
In a preferred embodiment, also comprise: impact member, be positioned at described test position place, be used for the touch-screen that moves to described test position place is impacted.
In a preferred embodiment, containing component is specially framing mask, and framing mask comprises: carry the bottom of touch-screen to be measured, and the fixed part that withholds touch-screen to be measured.
In a preferred embodiment, an end of elastomeric element is fixed by buckle replacing section.
As shown in Figure 1, comprise in the LCDs: array base palte, color membrane substrates, touch-screen, liquid crystal and chock insulator matter.
In the proving installation based on energy conservation foundation, the LCDs that includes touch-screen is positioned at the top of spring and is received parts fixes, and spring is in initial position at this moment.Can adopt different springs, and different stroke h, to determine the critical break-up point of touch-screen, calculate the energy that touch-screen absorbs in critical break-up point.
In a preferred embodiment, elastomeric element is the first spring, has the first elasticity coefficient.
In a preferred embodiment, elastomeric element is the second spring, has the second elasticity coefficient.
The stroke of spring between initial position and test position is positioned at the impulse stroke of spring, and the first spring and the second spring all should meet law of elasticity (Hooke's law), and wherein, the first elasticity coefficient k1 and the second elasticity coefficient k2 can be different.
In an application scenarios, as shown in Figure 1, spring is in vertical laying state, and the process of the intensity of test touch screen comprises:
As shown in Figure 1, initial time lies in the top of spring with touch-screen, makes touch-screen be in horizontality and without perk and outstanding; Adopt framing mask to guarantee that touch-screen does not shake or is shifted.Applied energy is analyzed as can be known, and touch-screen has elastic potential energy 1/2*k*x in initial position
2, wherein, k is elasticity coefficient, and x then is the deformation quantity that spring produces when being in initial position, and this deformation x should be positioned at the impulse stroke of spring.
As shown in Figure 3, decontrol spring, spring is stretched voluntarily, the spring after the release pushes away touch-screen toward a test position, and the most advanced and sophisticated teat on the surface of test position place touch-screen with impact member impacts mutually.
Analyze in this process energy variation as can be known, the elastic potential energy of spring is decomposed into two parts at this moment: the energy of first is the gravitional force m*g*h that touch-screen is elevated rear increase, wherein, m is the quality of touch-screen, g is gravity coefficient, h be touch-screen from initial position move to test position the stroke of process;
The energy of second portion then is touched to shield and absorbs, and second portion might cause touch-screen chipping, its role is to detect the intensity of touch-screen.
In an application scenarios, as shown in Figure 2, spring is in the horizontal positioned state, adopts the intensity of following method test touch screen, and method comprises:
Step 2 arranges spring and is in an initial position, is in energy accumulating state at the spring of this initial position, is 1/2*k*x in the elastic potential energy of the touch-screen of initial position
2, k is the elasticity coefficient of spring;
Step 3, retracting spring, touch-screen is pushed away toward a test position by spring, because touch-screen moves at surface level all the time, need not to consider the variation of gravitional force, thereby touch-screen is at test position place shock parts absorbed energy, and touch-screen is the energy that touch-screen absorbs at the test position place in the elastic potential energy of initial position.
Adopt this programme advantage afterwards to be: spring promotes touch-screen from initial position to test position, the power that touch-screen bears at the test position place is relevant with the elasticity coefficient k of spring and stroke h, analyze in this process energy variation as can be known, spring is punished for two parts at test position at the energy that initial position contains: the energy of first is the gravitional force m*g*h that touch-screen is elevated rear increase, the energy of second portion then is knocked parts and absorbs, second portion might cause touch-screen chipping, wherein, if touch-screen is not elevated the energy of then not considering first.Because the stroke of spring between initial position and test position meets law of elasticity, therefore can guarantee all to be consistent and to meet test condition for the each time strength test of touch-screen, namely can be by accurate data, thereby obtain the accurate intensive parameter of touch-screen, eliminated the uncertainty in the standardized test process.
The above is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
