Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The technical scheme disclosed by each embodiment of the invention is described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 15, an embodiment of the present invention discloses a terminal device, which includes a metal housing 100 and a touch sensing key 200.
The metal shell 100 is a basic component of the terminal device, and the metal shell 100 can provide a mounting base for other components of the terminal device. In the embodiment of the present invention, the components of the touch sensing key 200 are directly or indirectly mounted on the metal housing 100, so that the touch sensing key 200 is mounted on the metal housing 100.
In the embodiment of the present invention, the material of the metal housing 100 is a metal material, for example, the metal housing 100 is made of an aluminum alloy material, and the embodiment of the present invention is not limited to the specific material of the metal housing 100.
The touch sensing key 200 includes a metal touch panel 210, an insulating part 220, and a sensing circuit board 230. The metal touch panel 210 is used for a finger of a user to touch, the metal touch panel 210 is also made of a metal material, the insulating part 220 is arranged around the metal touch panel 210, the metal touch panel 210 is arranged on the metal shell 100 through the insulating part 220, and the metal touch panel 210 is insulated from the metal shell 100 through the insulating part 220, in this case, no conductive phenomenon exists between the metal touch panel 210 and the grounded metal shell 100.
The sensing circuit board 230 is disposed at the inner side of the metal housing 100, and the sensing circuit board 230 is insulated from the metal touch panel 210, so that a capacitive structure is formed between the metal touch panel 210 and the sensing circuit board 230, and when a finger is placed on the metal touch panel 210, the sensing circuit board 230 senses a change of the capacitance of the metal touch panel 210. There are various ways of insulating the sensing circuit board 230 from the metal touch panel 210, for example, the sensing circuit board 230 is disposed in the inner cavity of the metal housing 100, and a gap is formed between the sensing circuit board 230 and the metal touch panel 210, so that insulation is achieved through air. Of course, the sensing circuit board 230 and the metal touch panel 210 may be insulated and isolated by the adhesive layer 300 described below.
Specifically, the sensing circuit board 230 includes touch sensing areas 231, and the touch sensing areas 231 are disposed opposite to the metal touch panel 210, so that each touch sensing area 231 can detect a capacitance change of the metal touch panel 210 opposite thereto when in operation, thereby forming a touch signal.
It should be noted that, like the non-metal touch panel in the prior art, the capacitive structure is formed between the metal touch panel 210 and the sensing circuit board 230 in the embodiment of the present invention, and after the finger is placed on the metal touch panel 210, the capacitance between the metal touch panel 210 and the sensing circuit board 230 can be changed and can be detected by the sensing circuit board 230. In the embodiment of the present invention, the detection principle, the detection process and the formation of the touch signal of the sensing circuit board 230 for detecting the capacitance change of the metal touch panel 210 are all known techniques, and are not described herein.
The terminal device disclosed in the embodiment of the present invention improves the structure of the existing terminal device, changes the nonmetal touch panel in the prior art into the metal touch panel 210, installs the metal touch panel 210 on the metal shell 100 through the insulation part 220, and realizes insulation and isolation between the metal touch panel 210 and the metal shell 100 through the insulation part 220, and simultaneously, the metal touch panel 210 is insulated and isolated from the induction circuit board 230, so that the metal touch panel 210 can be prevented from being grounded, thereby the metal touch panel 210 and the induction circuit board 230 form a capacitance structure, and when the finger of a user contacts the metal touch panel 210, the induction circuit board 230 senses the change of capacitance, thereby achieving the purpose of finally forming a touch signal. Because the metal touch panel 210 and the metal housing 100 are both made of metal, the appearance performance of the terminal device can be improved, so that the user can achieve better visual experience.
Meanwhile, compared with the conventional touch unit made of a non-metal material, the larger the thickness of the touch unit made of the non-metal material is, the more easily the sensing function of the sensing circuit board is reduced, and the metal touch panel 210 is made of a metal material, so that the sensing of the sensing circuit board 230 is not affected.
As described above, the sensing circuit board 230 is disposed at the inner side of the metal case 100, and the sensing circuit board 230 may be mounted in various ways. Specifically, the induction circuit board 230 may be adhered to the inner surface of the metal housing 100, and referring to fig. 1, the induction circuit board 230 may be adhered to the inner surface of the metal housing 100 through the adhesive layer 300. Specifically, the adhesive layer 300 may be an insulating adhesive layer, and the induction circuit board 230 may be insulated from the metal touch panel 210 by the insulating adhesive layer.
In order to further improve the external appearance of the terminal device, in a more preferred aspect, the outer side surface of the metal case 100 may have the same color as the outer side surface of the metal touch panel 210. On the premise that the color of the outer side surface of the metal housing 100 is the same as the color of the outer side surface of the metal touch panel 210, in order to facilitate the user to touch the metal touch panel 210, the color of the outer side surface of the metal housing 100 and the color of the outer side surface of the metal touch panel 210 may be different from the color of the outer side surface of the insulating portion 220, so that the area surrounded by the insulating portion 220 can be reminded of the user to be the metal touch panel 210, and further, the user can control the metal touch panel 210 more accurately.
Of course, the color of the outer side surface of the metal case 100 may be different from the color of the outer side surface of the metal touch panel 210. Similarly, the color of the outer surface of the metal case 100 may be the same as the color of the outer surface of the insulating part 220, and the color of the outer surface of the metal touch panel 210 may be the same as the color of the outer surface of the insulating part 220.
It should be noted that, the outer surface mentioned above refers to a surface of the corresponding member facing away from the inner cavity of the metal housing 100.
There are various ways to realize the same color of the outer side surface of the metal housing 100 and the outer side surface of the metal touch panel 210, for example, the metal housing 100 and the metal touch panel 210 are made of the same material. For another example, the outer surface of the metal case 100 and the outer surface of the metal touch panel 210 may be provided with a cover layer having the same color, for example, the cover layer may be a paint layer.
The metal touch panel 210 may be mounted on the metal case 100 through the insulating part 220 in various manners. For example, the metal case 100 may be provided with a mounting hole, and the metal touch panel 210 may be positioned in the mounting hole and fixedly connected to the metal case 100 through an insulating part 220 surrounding the metal touch panel 210. The metal touch panel 210 and the insulating portion 220 jointly block the mounting hole, in this case, the inner side surface of the metal touch panel 210 is located inside the metal housing 100, and on the premise that the induction circuit board 230 is fixed on the inner side surface of the metal housing 100, the induction circuit board 230 is insulated from the metal touch panel 210 by an insulating adhesive layer.
Of course, the metal casing 100 may also be provided with a mounting groove, and the metal touch panel 210 may be fixed in the mounting groove through the insulating portion 220, and insulation between the metal touch panel and the metal casing 100 is achieved through the insulating portion 220.
In general, the touch sensing key 200 may be disposed at a plurality of positions of the metal case 100, in general, the metal case 100 may include the middle frame 110, and the metal touch panel 210 and the insulating part 220 may be mounted on the middle frame 110, in which case the touch sensing key 200 can fully utilize the space of the middle frame 110, thereby avoiding occupation of the panel space of the terminal device.
In order to further improve the external appearance of the terminal device, in a more preferred aspect, the outer side surface of the middle frame 110, the outer side surface of the metal touch panel 210, and the outer side surface of the insulating part 220 may be coplanar. The coplanar structure can also improve the gripping performance of the terminal equipment. In a more preferred embodiment, the outer surface of the middle frame 110, the outer surface of the metal touch panel 210, and the outer surface of the insulating portion 220 may be located in the same arc surface.
In the terminal device disclosed in the embodiment of the present invention, the shape of the metal touch panel 210 may be various, for example, the metal touch panel 210 may be a circular plate, the insulating portion 220 may be an annular structural member, and of course, the metal touch panel 210 and the insulating portion 220 may also be other structures, as will be described later.
The terminal device disclosed in the embodiment of the present invention may include one metal touch panel 210, or may include at least two metal touch panels 210, and the embodiment of the present invention does not limit the specific number of metal touch panels 210. In order to better sense the capacitance change between each metal touch panel 210 and the sensing circuit board 230, the touch sensing areas 231 may be disposed opposite to each metal touch panel 210, that is, one touch sensing area 231 is disposed opposite to one metal touch panel 210, so that the corresponding touch sensing area 231 is configured for each metal touch panel 210, and thus the sensing effect can be improved.
In a more preferred embodiment, the metal touch panels 210 may be arranged in a row, and any two adjacent metal touch panels 210 are spaced apart. In this case, the user can slide in the arrangement direction of the metal touch panels 210, so that the respective metal touch panels 210 can be sequentially touched.
Similarly, the number of the insulating parts 220 may be one or at least two, and the terminal device disclosed in the embodiment of the present invention does not limit the specific number of the insulating parts 220. In a specific embodiment, the number of the insulating parts 220 may be the same as the number of the metal touch panels 210, and the insulating parts 220 are in one-to-one correspondence with the metal touch panels 210. Of course, the number of the insulating portions 220 may be one, and the insulating portions 220 may include a surrounding portion 221 and a spacing portion 222, where the surrounding portion 221 surrounds all the metal touch panels 210, and each two adjacent metal touch panels 210 may be insulated and isolated by the spacing portion 222. Such a structure is advantageous in simplifying the structure of the insulating part 220 when insulating and isolating the plurality of metal touch panels 210.
As described above, the metal touch panel 210 may be a circular plate, and of course, the metal touch panel 210 disclosed in the embodiment of the invention may be a bar-shaped plate, and in particular, the extending direction of the metal touch panel 210 may intersect with the arranging direction of the metal touch panel 210. For example, the extending direction of the metal touch panel 210 may be perpendicular to the arrangement direction of the metal touch panel 210.
Specifically, the metal touch panel 210 may be a straight strip-shaped plate, and of course, the metal touch panel 210 may be a strip-shaped plate with other shapes, for example, at least one of the metal touch panels 210 may include a first bending section and a second bending section, the first bending section is connected with the second bending section, and the bending directions of the first bending section and the second bending section are opposite. The embodiment of the present invention does not limit the specific shape of the metal touch panel 210.
The terminal device disclosed by the embodiment of the invention can be a smart phone, a tablet personal computer, an electronic book reader, a wearable device (such as a smart watch) and the like, and the embodiment of the invention is not limited to the specific type of the terminal device.
Based on the terminal device disclosed in the embodiment of the present invention, the embodiment of the present invention discloses a control method for a terminal device, and in the related terminal device, the number of touch sensing areas 231 is at least two, the touch sensing areas 231 are arranged opposite to the metal touch panels 210 one by one, and the touch sensing areas 231 can be arranged in rows, and any two adjacent metal touch panels 210 are arranged at intervals. Under the premise, the disclosed control method comprises the following steps:
step one, the capacitance change between the metal touch panel 210 and the touch sensing area 231 is detected.
In the terminal device disclosed in the embodiment of the present invention, after a finger is placed on the metal touch panel 210, the capacitance between the metal touch panel 210 and the touch sensing area 231 is changed, and the touched metal touch panel 210 can be determined by detecting the capacitance change, and the capacitance change can be detected by the touch sensing area 231.
Step two, determining a touch sensing area 231 sensing the capacitance change and a sensing sequence of the touch sensing area 231 according to the capacitance change;
in the control method disclosed in the embodiment of the present invention, according to the capacitance change determined in the step one, the touch sensing area 231 sensing the capacitance change and the sensing sequence of the touch sensing area 231 can be determined.
Step three, determining the sliding direction of the finger according to the induction sequence;
in a specific manipulation process, the finger sliding may sequentially pass through different touch sensing areas 231, so that the finger sliding direction of the user can be determined through the sensing sequence of the touch sensing areas 231.
Specifically, the touch sensing areas 231 may be located in the same plane coordinate system, and each touch sensing area 231 has a corresponding coordinate value in the plane coordinate system, and the sensing sequence in the second step is determined by determining the coordinate value of the touch sensing area 231 sensing the capacitance change, and the sensing sequence is consistent with the finger sliding direction, so that the finger sliding direction can be determined according to the sensing sequence.
And step four, forming corresponding sliding touch signals according to the sliding direction of the finger.
And D, according to the finger sliding direction determined in the third step, forming a corresponding sliding touch signal. Different finger sliding directions are used for forming different sliding touch signals, so that terminal equipment can be controlled finally.
