Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a key testing device provided in the present application.
The key testing device 100 can be used for detecting the touch sense of the key, and certainly can also be used for detecting whether the key can be triggered, so that the pressing force of the detected and selected key is in a proper pressure range, and a user obtains uniform touch sense when operating the key.
In the field of electronic products, the touch sense of the key is sensitive or sluggish, which brings some use illusion to users. For example, the keys of the electronic product are sensitive, and when the keys are triggered, the feedback received by the user is not obvious, so that the user may continue to press the keys; when the key is rather stiff, the user applies a certain pressing force to the key, which may cause him to think that the key has been activated and is not actually activated. Therefore, the key test device 100 provided by the present application can select a type of keys with similar touch feeling according to a certain standard.
As shown in fig. 1 and 2, the key testing device 100 includes a base 10, a pressing component 20, a control system 30, a first detecting component 40 and a second detecting component 50, wherein the pressing component 20 presses a key to be detected carried on the base 10, and the control system 30 cooperates with the first detecting component 40 and the second detecting component 50 to control the whole detection process, record related data, and output a touch detection result of the key to be detected.
Specifically, the base 10 is used for carrying the key to be detected and is used as a carrier for the rest of the components. For example, the base 10 includes a box 12 and an assembly plate 14, the assembly plate 14 is connected to the box 12, the top side of the box 12 is used for bearing the key to be detected, or a platform 13 used for assisting positioning and bearing the key to be detected may be further disposed on the top side of the box 12, and a groove used for avoiding the pin of the key to be detected is disposed on the platform 13.
The pressing assembly 20 includes a pressing head 21 disposed above the base 10 and a driving mechanism 23 for driving the pressing head 21. The transmission mechanism 23 is disposed on the mounting plate 14 and can drive the pressing head 21 to move relative to the base 10 to press the key to be detected.
The control system 30 is used for controlling the transmission mechanism 23 to drive the pressing head 21 to approach the base 10, so as to press the key to be detected. The control system 30 may be disposed in the box 12, and connected to the transmission mechanism 23, and may regulate the operation state of the transmission mechanism 23 to regulate the operation state of the ram 21. For example, before the pressing head 21 reaches the key to be detected, the control system 30 may regulate the transmission mechanism 23 to operate rapidly, and after operating for a certain period of time, when the pressing head 21 approaches the transmission mechanism 23, the transmission mechanism 23 may be regulated to decelerate so as to slowly press the key to be detected, so as to obtain a pressing force with higher accuracy subsequently.
The first detection assembly 40 is arranged on the pressing assembly 20 and is used for detecting the pressing force borne by the key to be detected in the pressing process; the second detecting component 50 is disposed on the base 10 and is used for detecting whether the pressed key to be detected is in a conducting state.
After the key to be detected is in the on state, the control system 30 controls the transmission mechanism 23 to drive the pressing head 21 to move away from the base 10, and records the pressing force of the key to be detected at a plurality of time points before the pressing head 21 moves away from the base 10.
The control system 30 further outputs the result of the tactile sensation detection of the key to be detected based on the plurality of recorded pressing forces.
Specifically, during the pressing process of the key to be detected, the pressing force has a transition section of gradually increasing and then gradually decreasing, and then the pressing force tends to gradually increase. The control system 30 compares a first pressing force corresponding to a peak value of the pressing force in the transition section and a second pressing force when the pressing head 21 is far away from the base 10 with a first reference pressure and a second reference pressure, respectively, and judges that the tactile sensation of the button to be detected is acceptable when a difference value between the first pressing force and the first reference pressure and a difference value between the second pressing force and the second reference pressure are within a predetermined allowable range.
The key to be detected has a certain ability to resist deformation, so that before the pressing force required by the deformation of the key to be detected is not reached, the pressing force applied to the key to be detected is gradually increased, the key to be detected is not deformed, and the key cannot be triggered, so that the peak value of the pressing force in the transition section is the ability of the key to be detected to resist deformation, namely, the first pressing force is the pressing force borne by the key to be detected when the key to be detected starts to deform, then the pressing force detected by the first detection assembly 40 is gradually reduced by the pressing force of the released part of the deformation of the key to be detected, after a certain degree, the pressing force detected by the first detection assembly 40 is gradually increased, and the key is triggered to terminate in the section, namely, the pressing force recorded when the section is terminated is the second pressing.
The first pressing force determines the pressing difficulty of the key to be detected, the second pressing force determines whether the key to be detected is easy to trigger, so that the touch of the key to be detected is jointly determined, and whether the touch of the key to be detected is qualified can be judged by detecting the ranges of the first pressing force and the second pressing force.

The control system 30 further controls the actuator 23 to move the ram 21 away from the base 10 when the first sensing assembly 40 senses that the pressing force reaches the limit value. Because the key to be detected is invalid and the like, the key to be detected may not be triggered, and in order to prevent the pressure head 21 from further damaging the key to be detected, the base 10 or the base itself, the key to be detected can be considered invalid when the detected pressing force reaches the limit value, so that the situation that the key testing device 100 is damaged due to invalid pressing can be prevented by setting the pressing force limit value.
