Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by those skilled in the art based on the embodiments of the present invention belong to the scope of protection of the embodiments of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a touch control switch according to an embodiment of the present invention, where the touch control switch includes: a first capacitive sensing layer 1, a second capacitive sensing layer 2 and a controller 3. Wherein, first electric capacity response layer 1 and second electric capacity response layer 2 stack the setting, and first electric capacity response layer 1 is located the top of second electric capacity response layer 2.
The first capacitance sensing layer 1 and the second capacitance sensing layer 2 can both adopt epoxy resin materials or chlorinated polyethylene materials.
The first capacitance sensing layer 1 is provided with a first sensing contact 11, and the first sensing contact 11 may be a conductor layer made of a conductor material and is disposed on the surface or inside the first capacitance sensing layer 1 through processes such as printing and embedding.
The second capacitance sensing layer 2 is provided with a second sensing contact 21, and the second sensing contact 21 may be a conductor layer made of a conductor material and is disposed on the surface or inside of the second capacitance sensing layer 2 through processes such as printing and embedding.
When a finger or accumulated water of a user contacts the first capacitance sensing layer 1 or the distance from the first capacitance sensing layer 1 is smaller than a set distance, the surface of the finger or the accumulated water can be equivalent to a ground layer and equivalent to the first sensing contact 11 as a capacitor structure, so that a capacitance signal output by the first sensing contact 11 is changed, and whether finger touch operation possibly exists is detected for the first time.
In addition, the first sensing contact 11 may be equivalent to a ground layer at the same time, and equivalent to the second sensing contact 21 as a capacitor structure, when a touch pressing operation of a finger is performed, deformation of the first capacitance sensing layer 1 is caused, so that a distance between the first sensing contact 11 and the second sensing contact 21 is reduced, and a capacitance signal output by the second sensing contact 21 is changed. Because ponding can not arouse the deformation of first electric capacity response layer 1 usually to this can be through the electric capacity signal detection of second time, get rid of the false triggering that ponding leads to.
Meanwhile, the touch control switch structure provided by the embodiment can also prevent false triggering caused by extrusion stress around the touch switch. Because the application scenario of the touch control switch structure provided by this embodiment can be a vehicle console panel, such as acceleration of a vehicle, acceleration generated by deceleration, and contact between a user and the console panel, it is possible to generate extrusion stress on the first capacitance sensing layer 1 in the touch control switch, resulting in deformation of the first capacitance sensing layer 1, thereby changing the distance between the first capacitance sensing layer 1 and the second capacitance sensing layer 2, and further causing the capacitance signal output by the second sensing contact 21 to change, resulting in occurrence of false triggering, but in this embodiment, the capacitance signal change of the first sensing contact 11 needs to be detected first, only when the capacitance signal change of the first sensing contact 11 reaches a certain degree and is triggered, pressure triggering based on the second capacitance sensing layer 2 can be performed, thereby effectively avoiding false touch of the touch switch caused by reduction of the distance between the first capacitance sensing layer and the second capacitance sensing layer due to extrusion stress And the trigger reliability of the touch control switch is improved.
Certainly, a plurality of sensing contacts may be disposed in the first capacitance sensing layer 1, and at least the same number of sensing contacts are also disposed in the corresponding second capacitance sensing layer 2, so that a plurality of groups of touch key switches can be formed in this embodiment, as shown in fig. 2, a schematic structural diagram of a touch control switch provided in this embodiment is shown, in which two groups of sensing contacts are disposed, and two groups of touch key switches are correspondingly disposed.
Because this embodiment is when specifically using, the interval between first electric capacity response layer 1 and the second electric capacity response layer 2 can change, in order to avoid the air in the space between first electric capacity response layer 1 and the second electric capacity response layer 2 to produce too big resistance to user's the action of pressing, second electric capacity response layer 2 in this embodiment still is equipped with at least one through-hole to guarantee that this embodiment atmospheric pressure in the space between first electric capacity response layer 1 and the second electric capacity response layer 2 maintains unchangeably when specifically using.
In this embodiment, the first sensing contact 11 and the second sensing contact 21 are disposed correspondingly, and a gap structure is formed between the first sensing contact 11 and the second sensing contact 21 under the support of the supporting structure 4 between the first capacitive sensing layer 1 and the second capacitive sensing layer 2.
The supporting structure 4 can be made of hard material, and can also be made of flexible movable components such as springs.
The controller 3 is connected to the first sensing contact 11 and the second sensing contact 21, and specifically, the connection between the capacitive signal input interface of the controller 3 and the sensing contacts may be realized through a Flexible Printed Circuit (FPC) technology and a Printed Circuit Board (PCB) technology.
In this embodiment, the controller 3 may adopt an MCU having a capacitance signal detection function
(Microcontroller Unit, microcontrol Unit).
The working principle of the embodiment is as follows:
when a user performs a touch operation, a finger of the user may be equivalent to a ground layer, a capacitance structure is formed between the finger and the first sensing contact 11, and a capacitance signal output by the first sensing contact 11 is changed, so that the controller 3 detects the touch operation of the user for the first time, and simultaneously, when the finger of the user continues to be pressed downwards, the first sensing contact 11 forms a capacitance structure between the first sensing contact 11 and the second sensing contact 21 due to the equivalent of the finger to the ground layer, and due to the pressing operation of the user, a gap between the first sensing contact 11 and the second sensing contact 21 is reduced, and a capacitance signal output by the second sensing contact 21 is changed, so that the controller 3 detects the touch operation of the user for the second time.
Because the panel ponding of touch control switch can't cause the change in clearance between first response contact 11 and the second response contact 21, consequently above-mentioned structure can effectively avoid the touch switch maloperation that panel ponding produced, and then improves touch control switch's trigger reliability.
In order to further improve the accuracy of the touch control switch in the second detection, the first sensing contact 11 is arranged in the first capacitive sensing layer 1, and the second sensing contact 21 is arranged in the second capacitive sensing layer 2; the first sensing contact 11 and the second sensing contact 21 are aligned along the stacking direction of the first capacitive sensing layer 1 and the second capacitive sensing layer 2.
By so doing, the capacitor formed by the first and second sensing contacts 11 and 21 can more sensitively detect a change in capacitance signal due to a touch pressure of a user.
In order to better protect the touch switch structure, the present embodiment is further provided with a panel structure layer 51 and a bottom support layer 61; the panel structure layer 51 is arranged on one side of the first capacitance sensing layer 1 far away from the second capacitance sensing layer 2 through the first adhesive layer 52; the bottom support layer 61 is arranged on the side of the second capacitive sensing layer 2 remote from the first capacitive sensing layer 1 by means of a second adhesive layer 62.
Referring to fig. 3, fig. 3 is a flowchart of a touch control method according to an embodiment of the present invention, where the method is applied to any of the touch control switches described above, and specifically includes steps 11 to 13.
And 11, judging whether the capacitance signal change value of the first induction contact 11 in a first set time exceeds a first set threshold value.
Specifically, the first set threshold may be a capacitance signal change value detected before and after the user's finger touches the surface of the first capacitance sensing layer 1 or the surface of the panel structure layer 51.
The first set time period may be set to 40 milliseconds; the capacitance signal variation value in this step is the difference between the maximum value and the minimum value of the capacitance signal output by the first sensing contact 11 within 40 ms.
Certainly, in order to provide more intuitive and accurate feedback for the user, so that the user can know the identification state of the current touch control switch in time, in this step, if the current identification state exceeds the first set threshold, a touch trigger signal is generated and sent to the second reminding module, so as to remind the user that the touch operation of the first capacitance induction layer 1 is successfully triggered.
Specifically, the second reminding module can be a key indicator, a speaker for playing the touch success, or a display screen for displaying the touch success result.
And step 12, if the capacitance signal exceeds the first set threshold, setting the first inductive contact 11 as a ground layer, and determining whether the capacitance signal variation value of the second inductive contact 21 within a second set time period exceeds a second set threshold.
Since the surface water may also cause a sufficiently large capacitance signal change, when it is detected in this step that the capacitance signal change value of the first sensing contact 11 within the first set time period exceeds the first set threshold, it may be that the finger of the user is performing a touch operation, and it may also be that the finger is falsely triggered. Further detection is required at this point to avoid false triggering of this type which reduces the triggering reliability of the touch control switch.
Similarly, the extrusion stress causes the distance between the first capacitive sensing layer and the second capacitive sensing layer to be reduced, thereby causing the false triggering of the second sensing contact, but in this embodiment, the capacitive signal of the second sensing contact 21 is collected only when the capacitance signal variation value of the first sensing contact 11 within the first set time exceeds the first set threshold, so that the false triggering can be effectively avoided.
The second set time period may be set to 40 milliseconds; the capacitance signal variation value in this step is the difference between the maximum value and the minimum value of the capacitance signal output by the second sensing contact 21 within 40 ms.
Of course, if the capacitance signal variation value of the first inductive contact 11 in the first set duration does not exceed the first set threshold, the step 11 needs to be continuously returned to perform the determination and detection again.
And step 13, if the touch control signal exceeds the second set threshold, triggering a function corresponding to the touch control switch.
Specifically, when a user's finger touches the switch panel, a pressure is usually applied to the panel, and the pressure can cause the first capacitance sensing layer 1 to deform, so as to reduce the air gap between the first sensing contact 11 and the second sensing contact 21, thereby changing the capacitance of the capacitor formed by the first sensing contact 11 and the second sensing contact 21.
And the corresponding functions for triggering the touch control switch can be as follows:
and triggering a function corresponding to the capacitance signal change value of the second sensing contact in the touch control switch within a second set time length.
Specifically, in practical application, a control function may be pre-assigned to a possible value of a capacitance signal variation value of the second sensing contact 21 within a second set time period in advance, where the capacitance signal variation value represents a pressure of the first capacitance sensing layer 1, that is, a user may control different functions through the pressure.
Of course, if the capacitance signal variation value of the second inductive contact 21 in the second set time period does not exceed the second set threshold, it is necessary to continue returning to step 11 to perform the determination and detection again.
The second set threshold in this step may be set according to the trigger reliability, and the smaller the value of the second set threshold is, the higher the trigger reliability is.
Specifically, the touch control switch corresponds to different software and hardware functions (such as an air conditioner switch function, a temperature adjustment function, a seat movement function, and the like), and after the steps are accurately triggered, the execution hardware of the embodiment triggers the corresponding functions through a preset program flow.
Certainly, after the triggering, the present embodiment also sends a function triggering signal to a first prompting module such as a key indicator, a display or a speaker, and the like, so as to prompt a user of the function triggering result at the time.
When a plurality of sensing contacts are arranged in the first capacitive sensing layer 1 and the second capacitive sensing layer 2 in this embodiment, it is further necessary to determine whether the sensing contact in which the capacitive signal changes in the first capacitive sensing layer 1 corresponds to the sensing contact in which the capacitive signal changes in the second capacitive sensing layer 2, and if not, it is necessary to continue to return to the step 11 to perform the determination and detection again.
