Description
Technical Field
The embodiment of the utility model provides a relate to touch-control technical field, especially relate to a touch mouse.
Background
The touch control mouse is a novel mouse which is controlled by touch, is designed by adopting a capacitance sensing principle, and identifies the operation of fingers of a user on the surface of the mouse through a capacitance sensing layer in an upper shell of the mouse.
In order to facilitate the user to perform the touch operation, the upper casing of the touch mouse is usually designed as an integral structure, i.e., the upper casing is a complete structure without any keys. When a finger operates on the upper shell of the mouse (such as up-down sliding, left-right sliding, and gesture operation combining a single finger, double fingers and even multiple fingers), the capacitance of the corresponding area of the capacitance sensing layer tightly attached to the inner side of the upper shell of the mouse can be changed. The change of the capacitance is amplified and then judged as corresponding gesture operation by the main control chip, and the corresponding gesture operation is transmitted to corresponding equipment (such as a computer) and specific control (such as up and down page turning of a document, forward/backward movement of a webpage and a picture and the like) is realized.
In practice, the user often puts two fingers (often the index finger and the middle finger) on the left and right keys respectively and presses the left and right keys. In the foregoing touch detection process, the main control chip of the touch mouse determines that there are fingers on both the left and right buttons. In the touch mouse, the click operation is generally determined by a micro switch in the touch mouse, the pressure generated by the click causes the micro switch to be pressed, and when the click force is cancelled, the micro switch automatically rebounds. Due to the integrated design of the upper shell of the touch mouse, the micro switch can be pressed down when the left key or the right key is clicked. Therefore, even if the states of the capacitive sensing layer and the micro switch are combined, the main control chip still cannot judge whether the left key or the right key is pressed. Therefore, in one conventional method, it is determined that a left click is made when both of the left and right keys are touched and a click (either left or right click) is made. If the user wants to perform right click, the user needs to lift the finger placed on the left key, namely, the user leaves the mouse to judge that the right click is performed. Such a requirement is inconvenient for users who are accustomed to the conventional mouse operation, and particularly in some game operations, the frequency of right mouse button usage is quite high, and users may feel tired if the user needs to lift the finger of the left button for a long time to complete right click.
Therefore, how to quickly and accurately judge the click area of the touch mouse from the outside becomes a problem to be solved urgently.

Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention, and obviously, the described embodiments are only some embodiments, not all embodiments, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the scope protected by the embodiments of the present invention.
Example one
Referring to fig. 1, a schematic structural diagram of a touch mouse according to a first embodiment of the present invention is shown.
The touch mouse of the embodiment includes: the touch control device comprises a housing 102, a capacitance sensing layer 104 for sensing touch of the touch control mouse, a pressure sensor 106 for detecting pressure of clicking the touch control mouse, and a processor (not shown in the figure) which is electrically connected with the pressure sensor 106 and determines a clicked area of the touch control mouse according to a relation between pressure information acquired by the pressure sensor 106 and a pressure threshold.
A touch area is arranged at the upper part of the shell 102, and the capacitance sensing layer 104 is arranged at the position, corresponding to the touch area, of the inner surface of the shell 102; the pressure sensor 106 is disposed on an upper and/or middle shell included in the housing 102.
The housing 102 is a casing of the touch mouse, which may be generally enclosed by an upper casing, a lower casing, and sidewalls. In this case, the pressure sensor 106 may be provided on the upper case. In some touch mice, a middle housing is also disposed in the housing 102, in which case the pressure sensor 106 may be disposed on the middle housing, or on both the upper and middle housings.
It should be noted that, in practical applications, the touch mouse further includes other conventional settings, for example, the optical sensor and circuit for positioning, the main control chip, the micro switch, the wired or wireless communication circuit, the battery, and other parts, which can be implemented conventionally, and the embodiment of the present invention is not described in detail herein.
In one possible approach, a first pressing area (e.g., corresponding to the left key area) and a second pressing area (e.g., corresponding to the right key area) may be provided on the upper shell of the housing 102; in another possible manner, the housing 102 is provided with a third pressing area (e.g., corresponding to the middle key area) in addition to the first and second pressing areas. But not limited to this, in practical application, other pressing regions besides the first, second, and third pressing regions can be set according to actual requirements, and the embodiment of the present invention does not limit this.
At the time of setting, the pressure sensor may be provided corresponding to only a partial region of the plurality of pressing regions, for example, the pressure sensor 106 may be provided corresponding to only the first pressing region, or the pressure sensor 106 may be provided corresponding to only the second pressing region, or the pressure sensor 106 may be provided corresponding to only the third pressing region; alternatively, the pressure sensor 106 may be provided corresponding to both the first pressing area and the second pressing area, or the pressure sensor 106 may be provided corresponding to both the second pressing area and the third pressing area, or the pressure sensor 106 may be provided corresponding to both the first pressing area and the third pressing area, or the pressure sensor 106 may be provided corresponding to each of the first pressing area, the second pressing area, and the third pressing area. When other pressing areas are included in the housing 102, corresponding pressure sensors 106 may also be provided for the other pressing areas.
In order to enable a user using the conventional mouse to smoothly adapt to the touch mouse, similar to the conventional mouse, a micro switch is also arranged in the touch mouse, and the micro switch can provide click confirmation feedback (such as through sound and/or resilience) for the user and facilitate the user to quickly adapt to the touch mouse. Based on this, when the user performs the pressing operation in the corresponding pressing area, on one hand, the micro switch provides the confirmation feedback, and on the other hand, the pressure generated by the pressing operation is transmitted to the pressure sensor 106 corresponding to the pressing area through the housing 102 and the capacitive sensing layer 104, so as to trigger the pressure sensor 106 to generate the pressure information, and the pressed pressing area can be determined according to the relationship between the pressure information and the set pressure threshold. Wherein, the pressure threshold value can be set properly by those skilled in the art according to the actual requirement, and the embodiment of the present invention does not limit this.
For example, when the first and second pressing areas are both provided with pressure sensors, the determination may be performed according to pressure signals of the corresponding pressure sensors, and if the pressure received by the pressure sensor corresponding to the first pressing area is greater than or equal to the set pressure threshold, it is determined that the user has performed a pressing operation in the first pressing area, for example, has clicked the left key. For another example, if only the first pressing area is provided with the pressure sensor, the determination may be performed by combining confirmation feedback of the micro switch, and when it is detected that the micro switch is pressed, and it is determined that the pressure received by the pressure sensor is greater than or equal to the set pressure threshold, it is determined that the user has performed a pressing operation in the first pressing area, for example, a left key is clicked; if the micro switch is pressed, but the pressure received by the pressure sensor is smaller than the set pressure threshold value, the user is considered to press the second pressing area, and if the right key is clicked.
In addition, only one or a plurality of the set pressure thresholds may be provided, and by providing a plurality of the pressure thresholds, multistage pressure detection, for example, a mouse tap operation, or the like may be realized. Therefore, the pressing operation of the mouse can be flexibly set, and richer mouse functions can be realized, for example, the area of pressing the left key again is equivalent to double-click on the left key, or in some specific application scenes such as games, corresponding different game operations are respectively set for soft pressing and hard pressing, and the like.
It should be noted that, in the embodiment of the present invention, the capacitance sensing layer 104 may adopt a conventional configuration, and the gesture operation applied on the upper shell may be detected through the capacitance sensing layer 104.
In addition, in actual use, for further improving the use experience, a micro-vibration motor can be used for replacing a micro-switch, the micro-vibration motor can simulate the touch, heavy pressing, light pressing and the like of a roller in the traditional mouse, meanwhile, the clicking key stroke can be shortened, the appearance design of the mouse can be more flexible, and for example, the mouse can be designed into a completely closed waterproof and dustproof mouse and the like.
Through the scheme of the embodiment, the pressure sensor is added on the basis of the traditional touch mouse, and the pressure sensor is arranged on the upper shell and/or the middle shell in the shell of the touch mouse. When the touch mouse is pressed or clicked, the generated pressure is transmitted to the pressure sensor, the processor electrically connected with the pressure sensor detects the relation between the pressure information acquired by the pressure sensor and the set pressure threshold value, and the pressed area can be determined according to the relation. It is visible, the embodiment of the utility model provides a scheme passes through pressure sensor and pressure information and the comparison of pressure threshold value, can realize accurately detecting touch mouse fast and pressed regional function, and realizes simply, realizes with low costs. Moreover, the user does not need to perform extra operations (such as lifting the finger of the left key) and can be switched to use the touch mouse without obstacles under the condition that the use habit of the user is not changed, so that the use experience of the user in using the touch mouse is improved.
Example two
Referring to fig. 2, a schematic structural diagram of a touch mouse according to a second embodiment of the present invention is shown.
In this embodiment, for example, the pressure sensor of the touch mouse is a piezoresistive sensor, the upper shell of the housing includes a first pressing area and a second pressing area, and the piezoresistive sensor is disposed in both the first pressing area and the second pressing area, and the other situations can be implemented by referring to this embodiment and the first embodiment described above.
As shown in fig. 2, the touch mouse of the present embodiment includes an upper case 202 of the case, a capacitance sensing layer 204 for sensing a touch of the touch mouse, a piezoresistive sensor 206 for detecting a pressure of clicking the touch mouse, an integrated circuit chip 208 provided with a processor, and a lower case 210 of the case. The integrated circuit chip 208 provided with the processor is electrically connected to the pressure sensor 206, and determines the clicked area of the touch mouse according to the relationship between the pressure information acquired by the pressure sensor 206 and the pressure threshold. Piezoresistive sensors 206 include a first piezoresistive sensor 2062 and a second piezoresistive sensor 2064; the upper shell 202 includes a first pressing region 2022 and a second pressing region 2024.
In this embodiment, the capacitance sensing layer 204 is closely attached to the bottom side, i.e. the inner surface, of the upper shell 202 of the touch mouse, the first piezoresistive sensor 2062 and the second piezoresistive sensor 2064 are both located below the capacitance sensing layer 204, i.e. at a side away from the upper shell 202, and the first piezoresistive sensor 2062 and the second piezoresistive sensor 2064 are respectively disposed corresponding to the first pressing region 2022 and the second pressing region 2024, as shown in fig. 2, respectively located below the left and right finger pressing regions.
When a finger touches the upper shell 202 of the touch mouse, the capacitance of the corresponding area of the capacitance sensing layer 204 is changed. When a finger presses the first pressing region 2022 and/or the second pressing region 2024 (corresponding to left and right keys of the touch mouse), the generated pressure is transmitted to the corresponding piezoresistive sensor 206 through the upper case 202 and the capacitive sensing layer 204. For example, when the first pressing region 2022 is pressed, pressure will be transmitted to the first piezoresistive sensor 2062, and when the second pressing region 2024 is pressed, pressure will be transmitted to the second piezoresistive sensor 2064.
After the first piezoresistive sensor 2062 and/or the second piezoresistive sensor 2064 is stressed, the resistance thereof changes, and further, the resistance change can be converted into a voltage signal through a corresponding circuit, and the voltage signal is amplified and judged by the integrated circuit chip 208.
The lower case 210 of the touch mouse is used to support the upper structure including the above arrangement and bear other functional parts of the touch mouse, such as an optical sensor and circuit for positioning, a main control chip, a micro switch, a wired or wireless communication circuit, a battery, and the like.
Therefore, the touch mouse only needs to provide a structure for bearing the piezoresistive sensor and transmitting pressure, and the touch mouse is simple to implement and low in implementation cost.
Alternatively, for a touch mouse employing piezoresistive sensors, the capacitive sensing layer 204 may be combined with the piezoresistive sensors 206 by some process.
In one possible implementation, capacitive sensing layer 204 is disposed on a first flexible circuit board on which piezoresistive sensor 206 is also disposed, in which case capacitive sensing layer 204 and piezoresistive sensor 206 can be considered to be bonded together. Further alternatively, the integrated circuit die 208 is disposed on a second flexible circuit board, and the first flexible circuit board and the second flexible circuit board are electrically connected, in which case the capacitive sensing layer 204, the piezoresistive sensor 206, and the integrated circuit die 208 may be considered to be bonded together. In practice, the piezoresistive sensor 206 may be disposed on the first flexible circuit board, the integrated circuit chip 208 may be disposed on the second flexible circuit board, and the first flexible circuit board and the second flexible circuit board are electrically connected, in which case, the piezoresistive sensor 206 and the integrated circuit chip 208 may be considered to be combined together.
In another possible implementation, the capacitive sensing layer 204 and the piezoresistive sensor 206 may be disposed on different flexible circuit boards, respectively, for example, the capacitive sensing layer 204 is disposed on a third flexible circuit board, and the piezoresistive sensor 206 is disposed on a first flexible circuit board. The first flexible circuit board of the capacitance sensing layer 204 and the first flexible circuit board of the piezoresistive sensor 206 may be attached to each other, and the first flexible circuit board of the piezoresistive sensor 206 may be attached to one side of the third flexible circuit board of the capacitance sensing layer 204, which is far away from the upper case 202, or may be attached to one side of the third flexible circuit board of the capacitance sensing layer 204, which is close to the upper case 202, that is, the two flexible circuit boards do not have the requirement of the upper and lower relationship in position.
Alternatively, the piezoresistive sensor 206 may be integrated with the integrated circuit chip 208 by some PCB (Printed Circuit Board) process.
In one possible implementation, the piezoresistive sensors 206 are disposed on a flexible circuit board on which the integrated circuit die 208 is also disposed (e.g., soldered); alternatively, the piezoresistive sensor 206 is disposed on a rigid circuit board on which the integrated circuit chip 208 is also disposed. That is, the pressure sensor 206 is disposed on the same flexible circuit board as the integrated circuit chip 208 or the pressure sensor 206 is disposed on the same rigid circuit board as the integrated circuit chip 208. Alternatively, reinforcement (PI (polyimide, polyimide), steel plate reinforcement, etc.) may also be added. Further alternatively, the capacitance sensing layer 204 may also be disposed on the same flexible circuit board, i.e., the capacitance sensing layer 204 may be disposed on the flexible circuit board on which the pressure sensor 206 and the integrated circuit chip 208 are disposed. Optionally, when the capacitance sensing layer 204 is disposed on the third flexible circuit board, the flexible circuit board with the pressure sensor 206 and the integrated circuit chip 208 is attached to a side of the third flexible circuit board away from the upper case 202 or close to the upper case 202.
In another possible implementation, the piezoresistive sensor 206 may be disposed on a rigid or flexible board of a rigid or flexible board, and the integrated circuit chip 208 is disposed on the rigid or flexible board of the rigid or flexible board, accordingly.
In yet another alternative, the piezoresistive sensor 206 may be disposed on a first rigid circuit board and the integrated circuit chip 208 disposed on a second rigid circuit board, electrically connecting the first and second rigid circuit boards. For example, the piezoresistive sensors 206 and the integrated circuit die 208 are each distributed on separate rigid circuit boards, which are connected by a flexible circuit board, a flexible flat cable, or a common cable, etc.
Alternatively, the capacitive sensing layer 204 may be integrated with the integrated circuit chip 208 by some PCB process.
In one possible implementation, the capacitive sensing layer 204 may be implemented by a flexible circuit board, i.e., disposed on the flexible circuit board, and the integrated circuit chip 208 may be disposed on the flexible circuit board and reinforced (PI reinforced, steel plate reinforced, etc.). In another possible implementation, the capacitive sensing layer 204 may be implemented on a flexible board portion of a rigid-flex board, i.e., disposed on a flexible board of a rigid-flex board, and the ic chip 208 may be soldered on a rigid board portion of the rigid-flex board. In yet another possible implementation, the capacitive sensing layer 204 and the integrated circuit chip 208 may be distributed on separate flexible circuit board and rigid circuit board, and the two may be connected by a flexible circuit board, a flexible flat cable, or a common cable, as shown in fig. 3. Fig. 3 shows another structure of a touch mouse, and as can be seen from fig. 3, the capacitance sensing layer 204 is disposed on a flexible circuit board, and the integrated circuit chip 208 is disposed on a rigid circuit board, which are electrically connected by a flexible flat cable 212.
It should be noted that, in practical use, the combination method is not limited to the above-described combination method, and any suitable combination method may be adopted according to actual requirements.
In addition, the touch mouse in this embodiment includes an upper case 202, which is mainly used for carrying a capacitance sensing layer 204, a piezoresistive sensor 206 and an integrated circuit chip 208. However, in practical applications, a person skilled in the art may also adopt any appropriate structural design according to actual requirements, as long as there is a bearing structure similar to the upper shell 202, for example, a middle shell is disposed in the touch mouse, and the middle shell is used as a bearing object, or a structural design without a lower mouse shell, or an integrated design of the upper and lower shells, or a design of the vertical mouse, and the like.
Based on the arrangement of the piezoresistive sensors, when a finger clicks or presses the upper case 202 of the touch mouse, the upper case 202 is deformed. For piezoresistive sensors 206, the deformation may cause the piezoresistive sensor 206 to be squeezed or stretched, causing the resistance value of the piezoresistive sensor 206 to change. In this embodiment, the change is processed by an integrated circuit chip integrated with a processor.
One possible structure of the integrated circuit chip is shown in fig. 4, and as can be seen from fig. 4, the integrated circuit chip 208 is electrically connected to the pressure sensor (specifically, the piezoresistive sensor in this embodiment) and the main control chip. Conversion circuits are arranged in the integrated circuit chip 208, for example, two pressure sensors shown in fig. 4 are taken as an example, and two conversion circuits, namely, a conversion circuit 2082 and a conversion circuit 2084, are correspondingly arranged in the integrated circuit chip 208, and are used for converting pressure signals of the pressure sensors into voltage signals. It can be seen that each pressure sensor corresponds to one switching circuit. Each of the conversion circuits includes an amplifying circuit (specifically, a pre-stage amplifying circuit in this embodiment) and an analog-to-digital conversion circuit, the amplifying circuit amplifies the pressure signal, and the analog-to-digital conversion circuit converts the amplified pressure signal into a digital signal. In addition, in this embodiment, the integrated circuit chip 208 is further provided with an excitation power supply circuit 2086 and a processor 2088. The processor 2088 may be configured to receive the voltage signal sent by the conversion circuit (i.e., the voltage signal of the pressure information obtained by the pressure sensor), compare the voltage signal with a set pressure threshold, and determine whether the first pressing area and/or the second pressing area is pressed according to the comparison result.
Specifically, the integrated circuit chip 208 provides the required power to the pressure sensor through the excitation power circuit 2086 on the one hand; on the other hand, a weak analog pressure signal generated by the pressure sensor connected to the corresponding preceding stage amplifier circuit is amplified, converted into a digital signal by the analog-to-digital conversion circuit, and then sent to the processor 2088 for determination processing. The processor 2088 can determine whether a left key and a right key are pressed according to a preset pressure signal threshold value, and send the determination result to the main control chip, thereby realizing specific operation control.
But not limited to the structure of the integrated circuit chip described above, another possible structure of the integrated circuit chip is shown in fig. 5. In fig. 5, a multiplexing switch 2081 is disposed in the integrated circuit chip 208, and the plurality of pressure sensors are multiplexed by a multiplexer 2083 through the multiplexing switch 2081. Through the multiplexing switch 2081, the multiple pressure sensors share one pre-amplification circuit and one analog-to-digital conversion circuit, and the internal complexity of the integrated circuit chip 208 is reduced.
Therefore, in the embodiment, the excitation power circuit, the pre-stage amplifying circuit, the analog-to-digital conversion circuit and the processor are all integrated into the integrated circuit chip, and the space of the touch mouse can be greatly saved by integrating a plurality of circuits through the integrated circuit chip. In practical applications, the touch mouse further includes a touch chip for detecting a touched position of the touch mouse according to the capacitive sensing layer, and the excitation power circuit, the pre-amplification circuit, the analog-to-digital conversion circuit, and the processor may be integrated in the touch chip.
It should be noted that, in practical applications, the same functions as those of the integrated circuit chip 208 may be implemented by using discrete devices or a combination of a part of discrete devices and an integrated circuit chip, not limited to the manner of integrating a plurality of circuits by an integrated circuit chip. For example, the functions of the integrated circuit chip 208 may be implemented by discrete resistors, capacitors, inductors, power chips, operational amplifiers, instrumentation amplifiers, discrete analog-to-digital converters, multiplexing switches, processors, and so forth; alternatively, the excitation power supply circuit may implement the functions of the integrated circuit chip 208 described above by integrating the preceding stage amplifier circuit, the analog-to-digital conversion circuit, and the processor, and using a separate power supply chip.
That is, the excitation power circuit, the pre-amplifier circuit, the analog-to-digital conversion circuit, and the processor may be disposed in the touch mouse in any suitable form, including but not limited to a form that is independent, integrated on an integrated circuit chip, or integrated in a touch chip.
The system comprises an excitation power circuit, a pre-stage amplifying circuit, an analog-to-digital conversion circuit and a processor, wherein the excitation power circuit is used for providing power for the pressure sensor and the processor, the pre-stage amplifying circuit is used for amplifying an analog pressure signal of the pressure sensor, and the analog-to-digital conversion circuit is used for converting the amplified analog pressure signal into a digital signal; the excitation power circuit is electrically connected with the pressure sensor and the processor; one end of the preceding stage amplifying circuit is electrically connected with the pressure sensor, and the other end of the preceding stage amplifying circuit is electrically connected with the analog-to-digital conversion circuit; one end of the analog-to-digital conversion circuit is electrically connected with the preceding stage amplifying circuit, and the other end of the analog-to-digital conversion circuit is electrically connected with the processor.
For a piezoresistive sensor, it may be constructed from a single piezoresistive structure, or multiple piezoresistive structures may be designed in different topologies. FIGS. 6-9 illustrate piezoresistances of various topologies, wherein the piezoresistances are represented by resistance symbols with slanted arrows.
FIG. 6 shows the piezoresistance of a single-arm bridge structure, i.e. only one piezoresistance is formed, and the piezoresistive sensor is formed by dividing 1 piezoresistance and a common resistor; FIG. 7 shows another piezoresistive, single-arm bridge configuration, with a common resistor and 1 piezoresistive voltage division forming a piezoresistive sensor; FIG. 8 shows a half-bridge configuration of piezoresistors, 2 constituting a half-bridge piezoresistive sensor; figure 9 shows a piezoresistive full bridge configuration, with 4 piezoresistors making up the full bridge piezoresistive sensor. Preferably, the full-bridge piezoresistive sensor is adopted, so that the temperature drift phenomenon of a single piezoresistive can be effectively inhibited. It should be clear to those skilled in the art that in actual use, piezoresistive sensors consisting of one, two or even more piezoresistors or topological units thereof; the piezoresistive sensor is formed by at least one of a full-bridge structure, a half-bridge structure and a single-arm bridge structure; piezoresistive sensors formed by combining piezoresistors with different structures in series and parallel connection and the like can be applied.
In addition, the integrated circuit chip can be integrated with the touch chip or the main control chip.
At least one of the capacitance sensing layer 204, the piezoresistive sensor 206, and the integrated circuit chip 208 of the touch mouse may be embedded in the upper case 202, for example, by plastic molding.
Through the scheme of the embodiment, the pressure sensor is added on the basis of the traditional touch mouse, and the pressure sensor is arranged on the upper shell and/or the middle shell in the shell of the touch mouse.

Moreover, the pressure sensor is realized by adopting a piezoresistive sensor, so that the realization is simple and the realization cost is low.
EXAMPLE III
Referring to fig. 10, a schematic structural diagram of a touch mouse according to a third embodiment of the present invention is shown.
In this embodiment, for example, the pressure sensor of the touch mouse adopts a pressure volume sensor, the upper shell of the housing includes a first pressing area and a second pressing area, and the first pressing area and the second pressing area are both provided with the pressure volume sensor correspondingly, and the other situations can be realized by referring to this embodiment and the first embodiment described above.
As shown in fig. 10, the touch mouse of the present embodiment includes an upper case 302 of the case, a capacitance sensing layer 304 for sensing a touch of the touch mouse, a pressure-volume sensor 306 for detecting a pressure of clicking the touch mouse, an integrated circuit chip 308 provided with a processor, a middle case 310 of the case, and a lower case 312 of the case. The integrated circuit chip 308 provided with the processor is electrically connected to the pressure sensor 306, and determines the clicked area of the touch mouse according to the relationship between the pressure information acquired by the pressure sensor 306 and the pressure threshold. The pressure-capacitance sensor 306 includes a first pressure-capacitance sensor 3062 and a second pressure-capacitance sensor 3064, each of which includes an upper pole plate and a lower pole plate, as shown in fig. 10, the first pressure-capacitance sensor 3062 includes a first electrode (in this embodiment, an upper pole plate 3062a is illustrated) and a second electrode (in this embodiment, a lower pole plate 3062b is illustrated), the second pressure-capacitance sensor 3064 also includes a first electrode (in this embodiment, an upper pole plate 3064a is illustrated) and a second electrode (in this embodiment, a lower pole plate 3064b is illustrated), and the first electrode is attached to the capacitance sensing layer 304 or disposed on the upper case 302; the upper shell 302 includes a first compression region 3022 and a second compression region 3024.
In this embodiment, the capacitance sensing layer 304 is closely attached to the bottom side, i.e., the inner surface, of the upper case 302 of the touch mouse, the first pressure-capacitance sensor 3062 and the second pressure-capacitance sensor 3064 are both located below the capacitance sensing layer 304, i.e., on the side away from the upper case 302, and the first pressure-capacitance sensor 3062 (including the upper plate 3062a and the lower plate 3062b) and the second pressure-capacitance sensor 3064 (including the upper plate 3064a and the lower plate 3064b) are respectively disposed corresponding to the first pressing area 3022 and the second pressing area 3024, as shown in fig. 10, respectively located below the left and right finger pressing areas.
The upper and lower plates of the pressure-capacitance sensor may be made of conductive materials such as metal, and the lower plates (3062b and 3064b) are fixed on the middle case 310 of the touch mouse. Various media such as elastic foam, air and the like can be filled between the upper polar plate and the lower polar plate. When a finger touches the upper shell 302, a change in capacitance is caused in a corresponding area of the capacitance sensing layer 304. When a finger presses or clicks the first pressing area 3022 and/or the second pressing area 3024 (corresponding to left and right keys of the touch mouse), the generated pressure is transmitted to the corresponding pressure-capacitance sensor 306 through the upper shell 302 and the capacitance sensing layer 304. For example, when the first pressing region 3022 is pressed, pressure is transmitted to the first pressure/volume sensor 3062, and when the second pressing region 3024 is pressed, pressure is transmitted to the second pressure/volume sensor 3064.
The first 3062 and/or second 3064 pressure-capacitance sensors deform after being stressed, so that the distance between the upper and lower plates changes, and the capacitance changes can be converted into a voltage signal through a corresponding circuit and amplified, judged and the like by the integrated circuit chip 308 (specifically, a processor in the integrated circuit chip 308).
The lower case 312 of the touch mouse is used to support the upper structure including the above arrangement and bear other functional parts of the touch mouse, such as an optical sensor and circuit for positioning, a main control chip, a micro switch, a wired or wireless communication circuit, a battery, and the like.
It can be seen that the touch mouse needs to provide a structure (such as the upper case 302) for bearing the upper plate of the pressure-capacitance sensor and transmitting the pressure, and a structure (such as the middle case 310) for bearing the lower plate of the pressure-capacitance sensor.
Alternatively, for a touch mouse employing a piezo-capacitive sensor, the capacitive sensing layer 304 may be integrated with the integrated circuit chip 308 by some PCB process. In one possible implementation, the capacitive sensing layer 304 may be implemented by a flexible circuit board, i.e., disposed on a flexible circuit board, and the integrated circuit chip 308 may be soldered on the flexible circuit board and reinforced (PI reinforced, steel plate reinforced, etc.). In another possible implementation, the capacitive sensing layer 304 may be implemented on a flexible board portion of a rigid-flex board, i.e., disposed on a flexible board of a rigid-flex board, and the integrated circuit chip 308 may be soldered on a rigid board portion of the rigid-flex board. In yet another alternative, the capacitive sensing layer 304 and the integrated circuit chip 308 may be disposed on separate flexible circuit board and rigid circuit board, which may be connected by a flexible circuit board, a flexible flat cable, or a common cable.
In this embodiment, the upper case 302 of the touch mouse is mainly used for carrying the capacitance sensing layer 304, the upper plates 3062a and 3064a of the capacitance-pressure sensor 306, and the integrated circuit chip 308. The middle case 310 of the touch mouse mainly provides a support for the lower plates 3062b and 3064b of the pressure-capacitance sensor 306 without displacement. However, in practical applications, a person skilled in the art may also adopt any appropriate structural design according to actual requirements, as long as there exists a structure (such as the upper shell 302) similar to bearing the upper plate of the pressure-capacitance sensor and transmitting pressure and a structure (such as the middle shell 310) similar to bearing the lower plate of the pressure-capacitance sensor, for example, there is no structural design of the lower shell of the mouse, or an integrated design of the upper and lower shells, or a vertical mouse, or, as shown in fig. 11, in the touch mouse shown in fig. 11, the lower plates 3062b and 3064b of the pressure-capacitance sensor 306 are formed on the rigid circuit board 314 by applying copper, and there is no need to design a special lower plate or a middle shell of the touch mouse, which saves space, cost, and reduces the complexity of implementing the touch mouse.
Based on the above-mentioned configuration of the pressure-volume sensor, when the upper shell 302 of the touch mouse is clicked or pressed by a finger, the upper shell 302 deforms. For pressure-capacitance sensor 306, the deformation may cause the distance between the two plates of pressure-capacitance sensor 306 to change, resulting in a change in the capacitance of pressure-capacitance sensor 306. In this embodiment, the change is processed by a processor in the integrated circuit chip.
The structure and arrangement of the integrated circuit chip in this embodiment can refer to the related description in the second embodiment, and are not described herein again.
In addition, at least one of the capacitance sensing layer 304, the pressure-volume sensor 306, and the integrated circuit chip 308 of the touch mouse may be embedded in the upper case 302, for example, by plastic packaging.
Through the scheme of the embodiment, the pressure sensor is added on the basis of the traditional touch mouse, and the pressure sensor is arranged on the upper shell and/or the middle shell in the shell of the touch mouse. When the touch mouse is pressed or clicked, the generated pressure is transmitted to the pressure sensor, the processor electrically connected with the pressure sensor detects the relation between the pressure information acquired by the pressure sensor and the set pressure threshold value, and the pressed area can be determined according to the relation. It is visible, the embodiment of the utility model provides a scheme passes through pressure sensor and pressure information and the comparison of pressure threshold value, can realize accurately detecting touch mouse fast and pressed regional function, and realizes simply, realizes with low costs. Moreover, the user does not need to perform extra operations (such as lifting the finger of the left key) and can be switched to use the touch mouse without obstacles under the condition that the use habit of the user is not changed, so that the use experience of the user in using the touch mouse is improved.
