Description
TECHNICAL FIELD
[0001] The utility model relates to a kind of test device for testing the vibration function of touchpad, more particularly to a kind of test device for testing the vibration function of touchpad, which is extremely close or even consistent in position of sensing touch load and position of sensing vibration signal. BACKGROUND
[0002] Touchpad has been widely applied in many types of electronic products, such as smart phones, tablet computers, notebook computers, keyboards, etc. The existing touchpad has the function of generating vibration after being touched by external force. Such touchpad must be tested for vibration function at different positions after manufacturing.
[0003] For the vibration function test of touchpad, the prior art mostly uses load sensing elements such as load cells to sense touch load and acceleration sensing elements such as accelerometers to sense vibration signals.
[0004] Please refer to Figure 1 and Figure 2 , Figure 1 is the load-time graph sensed by the load cell of the prior art when the touchpad is struck. Figure 2 is the acceleration-time graph sensed by the accelerometer of the prior art when the touchpad is struck. As shown in Figure 1 , the prior art uses load cell to sense the pressing force that triggers the vibration function, that is, how much pressing force is needed to make the touchpad trigger the vibration function. As shown in Figure 2 , the prior art uses accelerometer to sense the vibration size, delay time and vibration duration of the vibration function generated by the touchpad. The delay time refers to the time difference between the time point when the touchpad is actually pressed and the time point when the vibration is specified to start. The vibration duration refers to the time difference between the time point when the vibration is specified to start and the time point when the vibration is specified to end.
[0005] However, due to the fact that the load cell and the accelerometer used in the prior art are independent sensing elements, each has a certain volume. This results in a large distance between the position actually sensed by the load cell and the position actually sensed by the accelerometer. That is, the data sensed is not all about the position that should be actually sensed.
[0006] In addition, the prior art also lacks a proper external force applying device to strike the touchpad, which also causes the time points of sensing touch load and vibration signal to deviate.
[0007] In addition, the prior art uses accelerometer to sense vibration signal, which is easily disturbed by other non-vertical direction vibration signals.
[0008] Therefore, it is necessary to design a new type of test device for testing the vibration function of touchpad to overcome the above-mentioned defects. Utility model content
