[0021] To fully understand this utility model, detailed structures and steps will be presented in the following description to illustrate the technical solution proposed by this utility model. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0022] This embodiment provides a sliding touch component 1, such as... Figure 1 As shown, it includes a substrate 11, a plurality of touch elements 12, and a plurality of signal output terminals; the plurality of touch elements 12 are arranged side by side on the substrate 11, and the plurality of signal output terminals are arranged on the side of the substrate 11; the touch elements are provided with a plurality of sensing portions 122 extending along the length direction of the substrate 11; the sensing portions 122 between two adjacent touch elements are arranged at intervals; each touch element is connected to a signal output terminal, and each signal output terminal is used to output the touch signal corresponding to the touch element.

[0023] As an example, multiple touch elements 12 are arranged side by side on the substrate 11 to cover the entire substrate 11, increasing the touch sensing area and thus improving touch accuracy. Multiple signal output terminals are arranged on the side of the substrate 11 to ensure normal output of touch signals. The touch elements are provided with multiple sensing parts 122 extending along the length of the substrate 11. The sensing parts 122 between two adjacent touch elements are arranged at intervals to increase the number of touch sensing points and improve touch sensitivity by extending the sensing parts 122 while keeping the cost of touch elements low. Each touch element is connected to a signal output terminal, and each signal output terminal is used to output the touch signal corresponding to the touch element. When the user slides left and right on the sliding touch component 1, they can sequentially contact the touch elements on the substrate 11, thereby generating a corresponding touch signal from the touch element in contact with it.

[0024] In this embodiment, the sliding touch component 1 includes a substrate 11, a plurality of touch elements 12, and a plurality of signal output terminals. The plurality of touch elements 12 are arranged side by side on the substrate 11, and the plurality of signal output terminals are arranged on the side of the substrate 11. The touch elements are provided with a plurality of sensing portions 122 extending along the length direction of the substrate 11. The sensing portions 122 between two adjacent touch elements are arranged at intervals. Each touch element is connected to a signal output terminal, and each signal output terminal is used to output the touch signal corresponding to the touch element. Thus, by arranging the sensing portions 122 between two adjacent touch elements at intervals, the number of touch sensing points can be increased and the touch sensing sensitivity can be improved by extending the sensing portions 122, while keeping the cost of the touch elements relatively low.

[0025] In one embodiment, the plurality of touch elements 12 include two first touch elements 122 and at least two second touch elements 123; the two first touch elements 122 are respectively located at both ends of the substrate 11; the at least two second touch elements 123 are located between the two first touch elements 122; the first touch element 122 includes a first body; at least two first sensing portions extending along the length direction of the substrate 11 are provided on one side of the first body; the second touch element 123 includes a second body; at least two second sensing portions extending along the length direction of the substrate 11 are provided on both the first and second sides of the second body; the at least two first sensing portions of the first touch element 122 and the at least two second sensing portions of the second touch element 123 are arranged alternately; in two adjacent second touch elements 123, the at least two second sensing portions on the first side of one second touch element 123 and the at least two second sensing portions on the second side of the other second touch element 123 are arranged alternately.

[0026] The first touch element 122 has two first touch elements 122 on only one side, and the second touch element 123 has at least two second sensing portions extending along the length direction of the substrate 11 on both the first and second sides. It can be understood that the first and second sides of the second touch element 123 are close to the first end and the second end of the substrate 11, respectively.

[0027] As an example, two first touch elements 122 are located at both ends of the substrate 11. Each first touch element 122 includes a first body. At least two first sensing portions extending along the length of the substrate 11 are provided on one side of the first body, thereby improving the touch sensitivity at both ends of the sliding touch assembly 1.

[0028] As an example, at least two second touch elements 123 are located between two first touch elements 122. Each second touch element 123 includes a second body. At least two second sensing portions extending along the length of the substrate 11 are provided on both the first and second sides of the second body, thereby ensuring the touch sensitivity of the middle area of ​​the sliding touch assembly 1.

[0029] In this embodiment, at least two first sensing portions of the first touch element 122 and at least two second sensing portions of the second touch element 123 are arranged in a cross-spaced manner; among two adjacent second touch elements 123, at least two second sensing portions on the first side of one second touch element 123 and at least two second sensing portions on the second side of the other second touch element 123 are arranged in a cross-spaced manner, thereby increasing the number of touch sensing points at both ends and in the middle area of ​​the sliding touch component 1, and thus improving the touch sensing sensitivity of the sliding touch component 1.

[0030] In one embodiment, the sensing part 122 is V-shaped. In this embodiment, the sensing part 122 is set in a V-shape to increase the number of touch sensing points at both ends and the middle area of ​​the sliding touch component 1.

[0031] In one embodiment, the gap between the interleaved sensing elements 122 is 0.6 mm to 1 mm. In this embodiment, ensuring that the gap between the sensing elements 122 is 0.6 mm to 1 mm reduces material costs while preventing interference between the touch elements.

[0032] In one embodiment, the touch element is a metal foil. Exemplarily, the metal foil can be made of copper, which has good conductivity and low cost, thus balancing touch sensitivity and cost.

[0033] In one embodiment, the substrate 11 is a PCB board or an FPC board, thereby facilitating the assembly of the sliding touch component 1.

[0034] This embodiment describes a touch control circuit, such as... Figure 2 As shown, the device includes a power supply 2, a main control chip 3, a switching circuit 4, an electrical load 5, and the aforementioned sliding touch component 1. The power supply 2 is connected to the power supply terminal of the main control chip 3 and the positive terminal of the electrical load 5, and is used to supply power to the main control chip 3 and the electrical load 5. The first terminal of the switching circuit 4 is connected to the negative terminal of the electrical load 5, and the second terminal of the switching circuit 4 is grounded. Multiple signal output terminals of the sliding touch component 1 are connected to the main control chip 3, and are used to output touch signals corresponding to the touch element. The control terminal of the main control chip 3 is connected to the control terminal of the switching circuit 4, and is used to output pulse modulation signals to the switching circuit 4 according to the touch signals, thereby controlling the conduction current of the switching circuit 4 and controlling the operating current of the electrical load 5.

[0035] For example, the power supply 2 is a 5V power supply. For example, the power supply 2 is connected to the power supply terminal of the main control chip 3 through resistor R7. The power supply terminal of the main control chip 3 is also grounded through a first capacitor C1 and a second capacitor C2. The first capacitor C1 and the second capacitor C2 are used to filter out interference signals from the power supply terminal.

[0036] As an example, such as Figure 3As shown, the main control chip 3 includes multiple signal receiving terminals (TCH0-TCH5). Each signal receiving terminal is connected to a signal output terminal of the sliding touch component 1 through a resistor (R6-R1) to receive the touch signal from the signal output terminal.

[0037] As an example, when the touch control circuit is working normally, the main control chip 3 controls the switch circuit 4 to turn on, thus connecting the power supply 2 and the electrical load 5, allowing the electrical load 5 to operate normally. When the main control chip 3 detects a touch signal from the user sliding the touch component 1, for example, when the user slides right, the main control chip 3 controls the switch circuit 4 to increase the conduction current through a pulse modulation signal, thereby increasing the operating current of the electrical load 5. When the user slides left, the main control chip 3 controls the switch circuit 4 to decrease the conduction current through a pulse modulation signal, thereby decreasing the operating current of the electrical load 5. For example, when the electrical load 5 is a fan, an increase in operating current results in an increase in fan speed, and a decrease in operating current results in a decrease in fan speed.

[0038] In one embodiment, the switching circuit 4 includes a first voltage divider circuit and a first switching transistor Q1; the first terminal of the first switching transistor Q1 is connected to the negative terminal of the electrical load 5, and the second terminal of the first switching transistor Q1 is grounded; the first terminal of the first voltage divider circuit is connected to the main control chip 3, the second terminal of the first voltage divider circuit is grounded, and the third terminal of the first voltage divider circuit is connected to the third terminal of the first switching transistor Q1.

[0039] As an example, the first voltage divider circuit includes a first resistor R8 and a second resistor R9, which are connected in series between the main control chip 3 and ground. The connection node between the first resistor R8 and the second resistor R9 is connected to the third terminal of the first switching transistor Q1.

[0040] As an example, the first switch Q1 is an NMOS transistor. The first terminal of the first switch Q1 is the drain, the second terminal of the first switch Q1 is the source, and the third terminal of the first switch Q1 is the gate.

[0041] In this embodiment, the main control chip 3 outputs a pulse modulation signal to drive the first switch Q1 to turn on or off through the first voltage divider circuit, and determines the magnitude of the conduction current when the first switch Q1 is turned on.

[0042] This embodiment provides an electronic device, including a housing and the aforementioned touch control circuit; a sliding touch component 1 is disposed on the outer surface of the housing; a power supply 2, a main control chip 3, a switching circuit 4, and an electrical load 5 are disposed inside the housing.

[0043] In one embodiment, the electrical load 5 includes a fan, and the housing has ventilation holes; the fan is disposed inside the housing and is positioned opposite to the ventilation holes to dissipate heat from the electronic equipment.

[0044] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
