Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
First embodiment
As shown in fig. 1, an embodiment of the present application provides a key structure, which can be applied to a body fat scale, and specifically includes: a substrate 10, wherein the substrate 10 includes a first touch area 101, and the first touch area 101 represents an area range that a user can touch when using the substrate; a main control circuit 20, as can be seen from fig. 2, the main control circuit 20 is not disposed on the substrate 10 having the first touch area 101, and the main control circuit 20 may be disposed below the substrate 10 and may be located inside the body fat scale; a conductive layer 30, the conductive layer 30 being also disposed on the substrate 10, and the conductive layer 30 including a first conductive block 301 and a second conductive block 302, the main control circuit 20 being electrically connected to the first conductive block 301 and the second conductive block 302, respectively. The aforementioned main control circuit 20 is electrically connected to the first conductive block 301 and the second conductive block 302, respectively, and includes two layers: firstly, the main control circuit 20 is directly connected with the first conductive block 301 and the second conductive block 302, which means that no other components are included between the conductive blocks and the main control circuit 20; second, the main control circuit 20 is indirectly connected to the first conductive block 301 and the second conductive block 302 (there may be other electrical components between the conductive blocks and the main control circuit), for example, the first conductive block 301 may be connected to the main control circuit 20 through electrodes, and the electrical components may be components such as resistors in addition to the electrodes.
The first conductive blocks 301 and the second conductive blocks 302 are distributed at intervals and disposed on the substrate 10 corresponding to the first touch area 101, so that when a user touches the first touch area 101, the first conductive blocks 301 and the second conductive blocks 302 can be conducted to generate a first conducting signal, and the first conducting signal is transmitted to the main control circuit 20.
Specifically, when the key structure designed above works, for example, when a user touches the first touch area 101 through a finger, the first conductive block 301, the finger of the user, and the second conductive block 302 form a path, and then a first conduction signal is generated and transmitted to the main control circuit 20, so that the main control circuit 20 receives the first conduction signal that the first conductive block 301 is communicated with the second conductive block 302, and the main control circuit 20 can recognize that the first touch area 101 is touched according to the received first conduction signal, that is, a key operation is generated in the first touch area 101.
In the key structure of above-mentioned design, through first conductive block and the second conductive block that sets up interval distribution in the first touch area of base plate, when making the user carry out the key touch in first touch area, first conductive block switches on and produces first conducting signal and then make main control circuit discern first conducting signal and then discern key operation, the problem that current body fat balance function button adopts the touch pad and touch identification chip to exist with high costs and the installation procedure is complicated has been solved, make the function that can realize the touch button through interval distribution's first conductive block and second conductive block, reduce the material of touch pad and touch identification chip, reduce the installation procedure, greatly practice thrift the cost.
In an alternative embodiment of this embodiment, as shown in fig. 2, the main control circuit 20 includes a resistor R4, a power supply 201 and a microcontroller 202, the substrate 10 further comprises a second touch area 102, the conductive layer 30 further comprises a third conductive block 303, a fourth conductive block 304, a first conductive trace 305 and a second conductive trace 306, the first conductive trace 305 corresponds to the first touch area 101, the second conductive trace 306 corresponds to the second touch area 102, and the first conductive trace 305 and the second conductive trace form resistors with different resistance values due to different lengths and widths, the third conductive bumps 303 and the fourth conductive bumps 304 are also disposed at intervals in the second touch area 102, when the user touches the second touch area, the third conductive block 303 and the fourth conductive block 304 are conducted, so as to generate a second conducting signal and transmit the second conducting signal to the main control circuit 20.
The aforementioned main control circuit and the conductive block may be indirectly connected (other electrical components may exist between the conductive block and the main control circuit), and based on the above structure of the main control circuit 20, the specific connection manner between the main control circuit 20 and the first conductive block 301 may be that the first conductive block 301 is electrically connected to the power supply 201 in the main control circuit 20 through the first conductive trace 305; the aforementioned main control circuit and the conductive block may be directly connected (there is no other electrical component between the conductive block and the main control circuit), on the basis that the main control circuit 20 has the above structure, the main control circuit 20 and the second conductive block 302 may be connected in a manner that the second conductive block 302 is connected to the first end of the resistor R4 in the main control circuit 20, meanwhile, the connection end of the second conductive block 302 and the resistor R4 is also electrically connected to the microcontroller 202 in the main control circuit 20, and the second end of the resistor R4 is grounded. Similarly, the connection mode of the third conductive block 303 corresponding to the second touch area 102 and the main control circuit 20 is specifically as follows: the third conductive block 303 is also electrically connected to the power supply 201 in the main control circuit 20 through a second conductive trace 306, the second conductive block 302 is connected to the first end of the resistor R4, and meanwhile, the connection end of the fourth conductive block 304 and the resistor R4 is also electrically connected to the microcontroller 202.
Specifically, when the key structure designed as above works, it is assumed that a user touches the first touch area 101 or the second touch area 102 with a finger to make the first conductive block 301 and the second conductive block 302 in the first touch area 101 and the third conductive block 303 or the fourth conductive block 304 in the second touch area 102 conductive, because the resistance values of the first conductive trace 305 in the first touch area 101 and the second conductive trace 306 in the second touch area 102 are different, the voltage division formed by the resistor R4 when the first touch area 101 and the second touch area 102 are conductive is different, and the voltage of the two touch areas in the first conductive signal and the second conductive signal is different, after the microcontroller 202 receives a certain conductive signal, the microcontroller 202 further determines whether the first touch area 101 is connected or the second touch area 102 is connected according to the voltage in the received conductive signal, and can identify which touch area, i.e., switch, was touched by the user. The resistance formed by the conductive traces in each touch area can be measured in advance, the voltage of the power supply 201 can be known in advance when being set, and the resistance of the resistor R4 can be known in advance, so that the voltage division of the first conductive trace 305 and the resistor R4 and the voltage division of the second conductive trace 306 and the resistor R4 can be obtained, and further the relationship between the voltage division and the corresponding touch area is stored in the storage unit of the microcontroller 202, and after the microcontroller receives a certain conduction signal, which touch area is touched can be determined.
In the key structure of the above design, through the first conductive routing in the first touch area and the second conductive routing with different resistances in the second touch area, the touched area is identified by using the different conductive routing with different resistances and the different partial pressures of the resistor R4, and then the key structure of the present application can be provided with a plurality of keys on the basis of the aforementioned cost saving, thereby improving the usability of the key structure of the scheme of the present application.
In an alternative embodiment of this embodiment, in addition to the aforementioned two touch areas, three or more touch areas, that is, three or more switches, may be provided in the present application, for example, when there are three touch areas, as shown in fig. 3, the substrate further includes a third touch area 103, the conductive layer 30 further includes a fifth conductive block 307, a sixth conductive block 308 and a third conductive trace 309, the third conductive trace 309 corresponds to the third touch area 103, the first conductive trace 305, the second conductive trace 306 and the third conductive trace 309 have different resistance values, the fifth conductive block 307 and the sixth conductive block 308 are also distributed and disposed on the substrate 10 corresponding to the third touch area 103 at intervals, when the fifth conductive block 307 and the sixth conductive block 308 are conducted, a third conducting signal can be generated, the fifth conductive block 307 is connected to the power supply 201 through the third conductive trace 309, the sixth conductive block 308 is connected to the same end of the resistor R4 as the fourth conductive block 304 and the second conductive block 302. the sixth conductive block 308 is also connected to the microcontroller 202.
Thus, according to the aforementioned manner, since the resistances of the first conductive trace 305, the second conductive trace 306, and the third conductive trace 309 are different, and further the voltage division of each conductive trace and the resistor R4 are different, the microcontroller 202 can obtain the voltage division magnitude of the touch area in the conducting signal according to the conducting signal transmitted by the touched area, and further identify which touch area is touched, and further identify which switch is triggered.
In an optional implementation manner of this embodiment, the materials of the first conductive trace 305, the second conductive trace 306, the third conductive trace 309, the first conductive block 301, the second conductive block 302, the third conductive block 303, the fourth conductive block 304, the fifth conductive block 307, and the sixth conductive block 308 may be ITO, and besides ITO, the materials may be conductive glue, conductive cloth, conductive leather, and the like that can be used for measuring impedance by contacting a human body on the surface of the substrate. The resistance values of the first conductive trace 305, the second conductive trace 306, and the third conductive trace 309 different from each other may specifically be: the first conductive trace 305, the second conductive trace 306 and the third conductive trace 309 have the same length but different width; the method can also comprise the following steps: the first conductive trace 305, the second conductive trace 306 and the third conductive trace 309 have the same width but different length; the method can also comprise the following steps: the lengths and widths of the first conductive trace 305, the second conductive trace 306, and the third conductive trace 309 are different, so as to form conductive traces with different resistance values, specifically, as shown in fig. 4, the first conductive trace 305, the second conductive trace 306, and the third conductive trace 309 can be conductive traces with different resistance values in the shape shown in fig. 4.
In an optional implementation manner of this embodiment, the spacing distribution manner of the two conductive blocks in one touch area may specifically have multiple forms, including a regular-shaped spacing distribution form and an irregular-shaped spacing distribution form, and since the distribution manner of the two conductive blocks in each touch area may be processed in the same way, the following description uses the first conductive block 301 and the second conductive block 302 in the first touch area 101 as an example to describe the distribution manner of the two conductive blocks in the touch area, as shown in fig. 4, the specific formation manner may be as follows:
the number of the first conductive blocks 301 and the second conductive blocks 302 may be plural, the plural first conductive blocks 301 include a first horizontal conductive sub-block 3011 and plural first vertical conductive sub-blocks 3012, the plurality of first vertical conductive sub-blocks 3012 are vertically connected to the first horizontal conductive sub-block 3011 at intervals and form a plurality of first slot regions 3013, the plurality of second conductive blocks 302 include a second horizontal conductive sub-block 3021 and a plurality of second vertical conductive sub-blocks 3022, the second plurality of vertical conductive sub-blocks 3022 are vertically connected to the second horizontal conductive sub-block 3021 and form a second plurality of slot regions 3023, the number of the first slot regions 3013 is the same as the number of the second vertical conductive sub-blocks 3022, the number of the second slot regions 3023 is the same as the number of the first vertical conductive sub-blocks, each first vertical conductive sub-block 3012 is disposed in a second slot region 3023, and each second vertical conductive sub-block 3022 is disposed in a first slot region 3013. In this way, since the vertical conductive sub-block is spaced from the slot region by a small distance, when a user touches the first touch region 101, a finger of the user becomes a medium for connecting the first conductive block 301 and the second conductive block 302, so that the first conductive block 301 and the second conductive block 302 are conducted.
In addition, the first conductive bumps 301 and the second conductive bumps 302 may also have an irregular spacing distribution in addition to the regular spacing distribution described above, for example, as shown in fig. 5, the first conductive bumps 301 and the second conductive bumps 302 are in a zigzag manner with parallel edges, and it is only necessary to keep the edges of the first conductive bumps 301 and the second conductive bumps 302 parallel and close to each other, but at the same time, they cannot be tightly attached, so that the two can be connected when touched by a user with a hand. The formation of the two conductive blocks in the remaining touch areas, such as the second touch area 102 and the third touch area 103, is similar to that, and is not described herein again.
In an optional implementation manner of this embodiment, the key structure may further include a first electrode 40 and a second electrode 50, when only the first touch area 101 exists, the first conductive block 301 corresponding to the first touch area 101 may be electrically connected to the main control circuit 20 through the first electrode 40, and the second conductive block 302 may be electrically connected to the main control circuit 20 through the second electrode 50. As shown in fig. 4, when there are multiple touch areas, i.e. multiple switches, for example, the aforementioned three touch areas, the aforementioned first conductive trace 305, second conductive trace 306, and third conductive trace 309 can be electrically connected to the power supply 201 through the first electrode 40, and the second conductive block 302, fourth conductive block 304, and sixth conductive block 308 can be connected to the microcontroller 202 through the second electrode 50, wherein the second conductive block 302, fourth conductive block 304, and sixth conductive block 308 can be specifically connected to the AD port of the microcontroller 202.
