Fig. 1 schematically shows an application scenario of an electronic device according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of a scenario in which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.
As shown in fig. 1, the electronic device of the embodiment of the present disclosure may be, for example, a notebook computer 100, and the cover plate may cover an area of the upper surface of the base of the notebook computer 100 excluding the keyboard, and may be a transparent glass plate.
The pressure touch pad (Forcepad)120 is a touch pad, and different from a conventional touch pad on a notebook computer, Forcepad adopts pressure tracking instead of a conventional mouse click, so that different input experiences can be brought to a user, a button does not need to be set, and various operations can be realized only by detecting the pressing force of the user. For example, in fast forwarding of a video file, a user can change the speed of fast forwarding by pressing the fast forwarding and then pressing the fast forwarding with a little force. For another example, when the user's finger slides left and right on the Forcepad, the display page may be switched, and when the finger is clicked, a click command may be input, or a multi-point control function may be implemented, which greatly increases the variety of operation modes and is helpful to improve the convenience of the user.
However, if the conventional pressure touch pad is disposed below the entire cover plate, the user presses the cover plate, and the pressing force cannot be sunk and transmitted to the pressure touch pad due to the obstruction of the cover plate, so that the pressure touch pad cannot detect the pressing force of the user, and the function is disabled.
The embodiment of the disclosure provides electronic equipment, which comprises a pressure touch pad structure, wherein the pressure touch pad structure can be arranged below a full-face cover plate, a touch sensing device can detect a touch position of a finger of a user, a mechanical detection device determines the pressing pressure degree of the finger of the user by detecting vibration waves generated when the finger presses the cover plate, and the operation intention of the user is known by combining the touch position and the pressing pressure degree, so that the electronic equipment executes corresponding operation, and provides vibration feedback through a feedback device to simulate real physical keys.
Fig. 2A schematically illustrates a partial structural schematic diagram of an electronic device 200 according to an embodiment of the present disclosure.
Fig. 2B schematically shows a schematic view of the section E-E in fig. 2A.
As shown in fig. 2A and 2B, the electronic apparatus 200 includes: a cover plate 210, a touch sensing device 220, a mechanical detection device 230, and a feedback device 240.
The touch sensing device 220 is stacked on the inner surface of the cover plate and used for sensing the touch operation of the operation body on the outer surface of the cover plate.
The mechanical detection device 230 is used for detecting stress information of the cover plate when the cover plate is subjected to touch operation of the operation body.
And the feedback device 240 is used for giving operation feedback to the operation body based on the stress information.
According to an embodiment of the present disclosure, the cover plate 210 may be a transparent glass plate, and the cover plate 210 may be covered on an area except for a keyboard on the upper surface of the base of the notebook computer, as shown in a gray portion in fig. 2A. The cover 210 includes an outer surface for receiving a touch operation of a user and an inner surface.
According to an embodiment of the present disclosure, the touch sensing device 220, the mechanical detection device 230, and the feedback device 240 may form a pressure touch pad (forced) structure.
According to an embodiment of the present disclosure, the touch sensing device 220 may be, for example, a capacitive touch pad, including a sensing surface, which may be attached to an inner surface of the cover plate 210. When an operation body such as a finger of a user performs a touch operation on the area of the cover plate 210 corresponding to the touch sensing device 220, a tiny current is led out from a contact point of the operation body on the touch sensing device 220, and the circuit board can accurately calculate a touch position according to the current value.
According to the embodiment of the present disclosure, the mechanical detection device 230 may be, for example, an elastic wave sensor, and is capable of detecting a vibration signal generated when the cover plate is subjected to a touch operation by the operation body, and obtaining force information of the cover plate based on the vibration signal. When the operation body performs touch operation on the cover plate, elastic vibration waves are formed on the cover plate, and the elastic wave sensor can detect the waveform of the elastic vibration waves and calculate the pressing force of the operation body according to the waveform.
The elastic wave sensor may detect force information when the user continuously presses with the same or different force. First, for the case where the user continues to apply the same force, there will typically be some fluctuation in the magnitude of the force applied by the user, which is determined by the slight fluctuation in the elastic waveform. Even under the condition that the force applied by the user does not change, the elastic wave sensor can detect the force information when the user continuously presses with the same force, because when the user releases the finger after pressing for a long time, the elastic wave can be detected, whether the user is pressing the input device before can be determined according to the elastic wave, and secondly, the coordinate information of the contact point can be acquired by adopting the touch sensing device 220 (such as a capacitive touch technology), and whether the user continuously presses the same position can be determined. And for the situation that the pressing force of the operation body in the pressing process changes, the change of the force can be determined directly according to the change of the received elastic waveform.
The number of the mechanical detection devices 230 may be one or more, and in the case that the number of the mechanical detection devices 230 is multiple, the mechanical detection devices may be uniformly distributed on the peripheral area of the touch sensing device 220.
According to the embodiment of the disclosure, since the physical key is cancelled, in order to enable better interactive experience when a user presses, the user needs to be fed back by operation, the feedback effect of the real physical key is simulated, and the user experience is improved. The feedback device 240 can generate a vibration force based on the force information and transmit the vibration force to the cover plate to provide operation feedback to the operating body.
According to the embodiment of the present disclosure, the feedback device 240 includes a driver and a deformable material, the deformable material deforms when the surface is affected by the electric field, the driver is configured to apply the electric field on the surface of the deformable material according to the stress information, drive the deformable material to deform, and provide a vibration force to feedback the operation body with the operation.
Fig. 3 schematically shows a deformation diagram of a deformable material according to an embodiment of the present disclosure.
As shown in fig. 3, the feedback device utilizes the inverse piezoelectric effect of the deformable material to perform vibration feedback, thereby achieving the effect of simulating physical keys. The piezoelectric effect is that when some dielectric (deformable material) is deformed by external force in a certain direction, polarization phenomenon is generated in the dielectric, and charges with opposite positive and negative polarities appear on two opposite surfaces of the dielectric. When the external force is removed, it returns to an uncharged state, and this phenomenon is called the positive piezoelectric effect. When the direction of the force changes, the polarity of the charge changes. Conversely, the inverse piezoelectric effect means that when an electric field is applied in the polarization direction of the dielectrics, the dielectrics are also deformed, and the deformation of the dielectrics disappears when the electric field is removed.
Under the condition that the cover plate stress information detected by the mechanical detection device meets the preset condition, the driver of the feedback device applies an electric field to the deformable material to drive the deformable material to deform, so that vibration force is provided to provide operation feedback for the operation body. The drive can be, for example, an electric field generator.
The number of the feedback devices may be one or more, and in the case that the number of the feedback devices is plural, the feedback devices may be equally distributed on the peripheral area of the touch sensing device 220.
The stress information of the cover plate comprises a pressure value of pressure applied to the cover plate in the direction perpendicular to the cover plate, the cover plate stress information meeting a preset condition can mean that the pressure value is larger than a preset pressure threshold value, and the controller sends a driving trigger signal to the driver under the condition that the pressure value is larger than the preset pressure threshold value.
According to the embodiment of the disclosure, a touch sensing device (for example, a capacitive touch pad) is attached to the inside of the whole glass cover plate and used for acquiring the position of a touch point, and meanwhile, a mechanical detection device (for example, an elastic wave sensor) is arranged in two side areas of the touch sensing device. Utilize the elasticity vibration wave signal on the mechanics detection device detection apron, realize listening the ascending dynamics of vertical direction, obtain the pressure value, combine touch point position and pressure value, can realize the pressure tracking function of pressure touch-control board (Forcepad), learn the user's intention, and then make electronic equipment carry out corresponding operation. Meanwhile, a vibration feedback device (for example, including a deformable material) is placed beside the touch sensing device, and when the mechanical detection device detects a pressing action, the vibration feedback device is triggered to perform touch feedback. Therefore, the pressure touch pad (Forcepad) can support the design of full-surface glass covering, the cover plate does not need to be hollowed, even if the pressure touch pad (Forcepad) is placed below the whole cover plate, and the operating force of a user cannot directly sink and be transmitted to the pressure touch pad (Forcepad), the pressing force of the user can be calculated by using a mechanical detection device (such as an elastic wave sensor) through detecting the vibration waves on the cover plate, meanwhile, when the pressing action of the user is detected, a good vibration feedback effect is provided by using a variable material, and the physical key is simulated more truly.
Fig. 4 schematically illustrates a connection schematic of a mechanical detection device and a feedback device according to an embodiment of the disclosure.
As shown in fig. 4, according to an embodiment of the present disclosure, the mechanical detection device 430 includes a sensor 431 and a controller 432;
the sensor 431 is, for example, the above-mentioned elastic wave sensor, and is configured to detect a vibration signal generated when the cover panel is subjected to a touch operation by the operating body, and the vibration signal is, for example, the above-mentioned waveform information, and transmit the vibration signal to the data collection unit of the controller 432.
The data collection unit of the controller 432 transmits the vibration signal collected from the sensor to the logic calculation unit, and the logic calculation unit obtains the force information of the cover plate according to the vibration signal and sends a driving trigger signal to the driver 441 of the feedback transmission device 440 through the trigger unit.
According to the embodiment of the disclosure, the controller may further determine a parameter of the electric field applied to the deformable material according to the pressure value when the pressure value is greater than the preset value, and send a driving trigger signal containing the parameter of the electric field to the driver, so that the driver applies the electric field to the surface of the deformable material according to the parameter of the electric field.
For example, when the pressing force of the operation body is different, the controller may control the driver to apply electric fields of different strengths to the surface of the deformable material, so that the deformable material deforms to different degrees to provide vibrating forces of different strengths; for another example, when the pressing force degrees of the operation body are different, different areas of the deformable material may be controlled to deform, specifically, when the pressing force degrees are large, an electric field may be applied to the entire surface of the deformable material to deform the entire deformable material, and when the pressing force degrees are small, the electric field may be applied only to the surface of a partial area of the deformable material to deform the partial area of the deformable material.

Thus, the elastic wave sensor can be directly attached to the inner surface of the cover plate to directly sense the vibration wave signal generated on the cover plate, and the controller of the mechanical detection device 530 can calculate the degree of pressing force of the operation body by combining the vibration wave signal, the position of the elastic wave sensor and the position of the touch point. The deformable material can also be directly attached to the inner surface of the cover plate to directly provide the cover plate with vibration force. The position structure can reduce the total thickness of the Forcepad device, so that the total thickness can be controlled within 1.0mm, and more internal space is saved for electronic equipment.
In other embodiments of the present disclosure, a circuit board, for example, a flexible circuit board FPC, may be disposed on the inner surface of the cover 510, and the controller of the mechanical detection device 230 and the driver of the feedback device 240 may be disposed on the flexible circuit board. The upper surface of the flexible circuit board is attached to the inner surface of the cover plate, and the sensing surface of the touch sensing device, the elastic wave sensor of the mechanics detection device 530 and the deformable material of the feedback device 540 can be attached to the lower surface of the flexible circuit board FPC.

In addition, the mechanical detection device and the feedback device can also be stacked on the inner surface of the touch sensing device, i.e. the cover plate, the touch sensing device, the mechanical detection device and the feedback device are stacked.
