At least the touch sensing layer 3 is connected with a processor of the electronic device, so that the processor obtains a target capacitance, determines a pressing position on the key layer or the dielectric substrate 2 based on the target capacitance, and outputs a target response based on the pressing position matching.
For example, the electronic device is a notebook computer, and the notebook computer has a mounting location, and the mounting location may be a location where the notebook computer is originally used for installing a keyboard. The input device is detachably arranged on the installation position of the electronic equipment. The input device in this embodiment includes a key layer having a plurality of keys 1, and a dielectric substrate 2 having a touch plane 16, wherein a touch sensing layer 3 is disposed between the key layer and the dielectric substrate, so that when a user presses a certain key 1 or inputs a touch operation on the touch plane 16, a target capacitance can be generated between the touch sensing layer 3 and the touch position of the key 1 or the touch plane 16. The processor in the electronic device is connected to at least the touch sensing layer 3, so as to obtain a target capacitance, and determine a pressing position on the key layer or the dielectric substrate 2 based on the target capacitance, so as to determine a content corresponding to the key 1 or a content corresponding to the touch position, and finally determine a target response based on the content, including specific response content.
Based on the disclosure of the above embodiment, it can be known that the beneficial effects of the present embodiment include that the input device has both a key layer and a touch plane 16, and the input device is detachably connected with the electronic device, so that a user can change the installation angle of the input device according to actual needs, and then switch to a state in which the key layer faces outwards for use, or switch to a state in which the touch plane 16 faces outwards for use. Through the design in this embodiment, the electronic device does not need to be changed in size, and the setting position of the keyboard or the touch control plane 16 does not need to be changed, so that the user can be ensured to obtain the feedback sense of the physical keyboard, the original use habit does not need to be changed, and meanwhile, the use requirements of the user on the keyboard and the touch control panel can be met.
Specifically, as shown in fig. 3 and 4, the key 1 in the present embodiment includes conductive particles 5, and the conductive particles 5 are disposed on a side of the key 1 facing the touch sensing layer 3. The input device further comprises a support 4 for mounting a plurality of keys 1, the support 4 is preferably made of an insulating material, such as plastic, and the plurality of keys 1 are mounted on the support 4 in rows, and the specific arrangement and mounting sequence are variable. In addition, for safety and aesthetic reasons, the side of the support 4 facing the key 1 is also provided with an insulating layer, such as an insulating layer made of PET (Polyethylene terephthalate PET for short, commonly known as polyester resin) material. Further, the support 4 in this embodiment may be directly or indirectly fixed on the touch sensing layer 3, and when the key 1 is pressed, the conductive particles 5 of the pressed key 1 penetrate through the support 4 and contact with the touch sensing layer 3.
Further, as further shown in fig. 3, the input device of this embodiment further includes a dielectric film 6, which may be made of a material having a dielectric constant of 1-10. For example, metal oxide, PET film, siO 2、SiNx、Al2O3. The dielectric film 6 in this embodiment is laid on the surface of the touch sensing layer 3 facing the key layer, and the support 4 is fixed on the dielectric film 6, specifically, may be fixed by an adhesive layer, such as an adhesive layer formed by OCA adhesive. The conductive particles 5 are in contact with the dielectric film 6 and further contact with the touch sensing layer 3, so that a sensing capacitance, i.e. a target capacitance, is formed therebetween.
Further, the key 1 in this embodiment further includes a key cap 7, and a scissor leg 8 disposed in the key cap 7 and abutting against the key cap 7 and the support 4, where the conductive particles 5 are connected to the shaft joint of the scissor leg 8, for example, are bonded, so that the scissor leg 8 can move along with the up-and-down movement of the shaft joint when being pressed to move. As shown in fig. 3 and 4, the overall height of the scissor leg 8 in the embodiment is at least the same as the sum of the heights of the bracket 4, the insulating layer and the adhesive layer when not pressed, so as to ensure that the scissor leg 8 can smoothly drive the conductive particles 5 to the position contacting the dielectric film 6 after being compressed when the key 1 is pressed.
Further, as further shown with continued reference to fig. 3 and 4, the key 1 of the present embodiment further includes a hemispherical rubber member 9 located in the key cap 7, the recess of the rubber member 9 facing the dielectric film 6. As shown in the figure, each end of the scissor leg 8 in the embodiment penetrates through the rubber member 9, and can assist in driving the rubber member 9 to deform when the key 1 is pressed. In practical application, a connecting part can be arranged on the bracket 4 at the position of each key 1 for rotating and connecting with each end of the scissor leg 8, limiting the scissor leg 8, and the outer edge of the rubber piece 9 can be erected and fixed on the insulating layer to realize limiting. Further, the rubber member 9 in this embodiment deforms, so that not only can the feedback of the key 1to the finger of the user be increased, and the touch feeling of the user be improved, but also the scissor legs 8 can be pushed, so that the conductive particles 5 are more easily driven to the contact position of the dielectric film 6, and meanwhile, the resilience force can be accumulated, so that the reset of the scissor legs 8 and the conductive particles 5 is further accelerated. The scissor leg 8 in this embodiment may be provided with a torsion spring at the shaft connection position, so that the scissor leg may be reset based on the elastic force of the torsion spring, or may not be provided with a torsion spring, and only the hemispherical rubber member 9 may be used to realize the reset.
Further, in the embodiment, the support 4 of the input device is provided with a hollow portion 10 corresponding to each key 1, and when the key 1 is pressed, the scissor legs 8 and the rubber member 9 drive the conductive particles 5 to prop against the dielectric film 6 through the corresponding hollow portion 10, so as to generate a sensing capacitor with the touch sensing layer. The hollow portion 10 may be a circular hole, and the aperture thereof may be the same as the inner diameter of the hemispherical hollow portion 10, or may be larger than the inner diameter.
Further, the dielectric substrate 2 in this embodiment may be made of a material with a dielectric constant between 1 and 10 and a certain supporting property, such as glass, plastic, etc., so that it can withstand the touch operation applied by the user, when the user presses the touch plane 16 with his hand, a sensing capacitor is formed between the pressing location and the touch plane 16 due to moisture in the human body, so that the overall capacitance between the touch plane 16 and the touch sensing layer is changed, and the processor can obtain the actual pressing location of the user on the touch plane 16 based on the abnormal point of the capacitance. With continued reference to fig. 5, the touch sensing layer 3 in this embodiment includes two metal layers and a dielectric layer sandwiched between the two metal layers. This allows the user to use both the key layer and the touch plane 16, and the touch sensitive layer can cooperate with the key layer to generate the target capacitance.
Further, as shown in fig. 3, the input device in this embodiment further includes an outer casing 11 with two open ends, such as a rectangular frame, the key layer, the dielectric substrate 2, and the touch sensing layer 3 are all disposed in the outer casing 11, for example, all are surrounded by the rectangular frame. The key 1 and the touch plane 16 are exposed outside through corresponding open ends, the electronic equipment is provided with a chute 14 with one open end or a chute 14 with two open ends, and the outer shell 11 can be detachably fixed on the electronic equipment through the chute 14, so that the key layer or the touch plane 16 is positioned outside the chute 14 for a user to use. Specifically, the outer casing 11 in this embodiment is provided with a handle 13, and a user can slide the input device through the outer casing 11 into the chute 14 of the electronic device by means of the handle 13, as shown in fig. 6, when the user slides in, the installation angle of the input device can be adjusted by means of whether the user needs to use the key layer or the touch plane 16, that is, by turning 180 degrees to adjust the installation angle, so that the key layer or the touch plane 16 is exposed outside the electronic device for the user to use. Through the device, a user does not need to be externally connected with a keyboard or a handwriting board and the touch pad, and the installation position of the keyboard and the touch pad relative to the electronic equipment is also required to be changed, so that the user can have the keyboard and the touch pad at the same time, and the convenience is remarkably improved for the use of the user.
Preferably, in order to improve the connection stability between the input device and the chute 14, a magnetic attraction piece, a buckle, a sliding rail or other structures may be added on the chute 14 and the outer housing 11, so as to assist the input device to be stably mounted and limited in the chute 14.
Further, as shown in fig. 3, in this embodiment, the touch sensing layer 3 is externally connected with a signal output terminal 12, which may specifically be a signal output terminal 12 formed by a circuit concentrating area, a plurality of output pins, etc., where the signal output terminal 12 may be mounted on a handle 13, so that the handle 13 shields the signal output terminal 12, thereby making the whole input device more attractive, and protecting the signal output terminal 12 from being damaged due to collision.
As further shown in fig. 5 and 6, in the present embodiment, signal receiving terminals 15 are disposed at the first position and the second position in the chute 14, specifically, on two opposite sidewalls of the chute 14, the signal receiving terminals 15 correspond to the positions between the signal output terminals 12. When the key layer is located outside the chute 14, the signal output terminal 12 on the input device is in contact connection with the signal receiving terminal 15 at the first position to transmit the target capacitance, when the touch plane 16 is located outside the chute 14, the signal output terminal 12 is in contact connection with the signal receiving terminal 15 at the second position to transmit the target capacitance, and the processor determines the target response by determining the position of the signal receiving terminal 15 transmitting the target capacitance and the target capacitance. Since there are two transmission channels between the input device and the processor, the processor can determine whether the user currently uses the keyboard or the touch control plane 16 as a data input means by determining whether the target capacitor is transmitted by the signal receiving terminal 15 at the first position or the second position, so as to rapidly determine the target response. For example, when the signal receiving terminal 15 at the first position transmits a signal, the processor can know that the use state of the input device is the keyboard function, the coordinate feedback takes the direction as a reference, and when the signal receiving terminal 15 at the second position transmits a signal, the processor can judge that the use state of the input device is the touch pad function, and the coordinate feedback is symmetrical with the keyboard function, so that the processor can accurately judge the pressed coordinate positions in different states, and further determine the target response.
Another embodiment of the present invention provides an electronic device, including an input device as in any one of the above embodiments.
The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention, the scope of which is defined by the claims. Various modifications and equivalent arrangements of this invention will occur to those skilled in the art, and are intended to be within the spirit and scope of the invention.
