[0028] Example 1

[0029] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0030] Please refer to Figures 1 to 3As shown, an embodiment of the utility model provides a keypad module, which includes: a touch switch panel 101, which is fixedly connected in an outer frame 103, and a control circuit board is provided on the inner back side; the control circuit board is provided with a control chip 201, and the control chip 201 is electrically connected to an interface connector 204, an I / O port connector 205 and the touch switch panel 101; the touch switch panel 101 is provided with a label icon, and a touch switch is provided at the corresponding position of the label icon, and the touch switch is electrically connected to the control chip 201.

[0031] In the above embodiment, in the keypad module of the present application, by setting a label icon on the touch switch panel 101, the function of a specific key on the keyboard can be intuitively displayed, thereby solving the problem that the keys on the traditional keyboard have no labels and are not intuitive enough; the control chip 201 processes the signal of the touch switch for signal input, on the one hand, provides a touch function so that information can be entered by touch, and on the other hand, converts the signal into a digital signal through the control chip 201. The control chip 201 can be a MC143150 neuron chip, which has better anti-interference performance, and can also change the label icon and function definition through external control, so that it has better application and adapts to more application scenarios.

[0032] Example 2

[0033] The embodiment of the utility model provides a keypad module, wherein an LED is further provided at the position of the touch switch, and the LED is electrically connected to the control chip 201. The LED can display the state of the touch switch, and can be connected to the same circuit as the touch switch. When the touch switch is triggered and turned on, the LED emits light, otherwise it does not emit light; the touch switch can be used to trigger the LED to switch the state, for example, it lights up when the touch switch is triggered, or the LED is set to a type that can display different colors, so that the LED displays different colors when the touch switch is triggered or not triggered.

[0034] By touching the label icons on the switch panel 101, the user can intuitively understand the function and corresponding operation of each button without additional guidance, thereby improving user experience and operating efficiency; compared with the traditional analog signal keyboard, the keypad module of the present application adopts a digital control circuit board and a corresponding control chip 201, so that the keyboard signal is converted into a digital signal, which is more stable and reliable and can better resist interference; the touch switch design makes the input more intuitive and quick, accelerates the speed and accuracy of information entry, and improves the overall efficiency; in addition, the keypad module of the present application is compact in design, occupies a small space, is suitable for the integration and application of various devices, and effectively saves the physical space of the device.

[0035] As an example, see Figure 4As shown, it is an LED driving circuit, which mainly uses a driving chip U2 which is a 555 chip, and controls it through a transistor T1. The B pole of the transistor T1 is connected to a capacitor C2. Its control principle can change the power supply of the LED by changing the capacitance value of C2, thereby controlling it to light up or not light up or display different colors. The capacitor C2 can form a loop with the above-mentioned touch switch, for example, in parallel or in series. Specifically, a resistor can be connected in series with the touch switch, etc. Alternatively, the circuit of the capacitive touch screen can be referred to, and the control can be achieved by changing the capacitor, which is connected to the capacitor C2, so that the above-mentioned LED can be linked controlled when touched.

[0036] It should be noted that LEDs with multiple colors can present different colors due to different voltages.

[0037] In a preferred embodiment, a buzzer 202 is also provided on the control circuit board, and the buzzer 202 is electrically connected to the control chip 201. The buzzer 202 can provide a sound prompt when a touch operation is performed. For example, when the brightness or volume is adjusted to the maximum or minimum, and then the adjustment is continued, a "beep" can be issued when the adjustment is made again to remind the user that the input is invalid.

[0038] In a preferred embodiment, the label icons are arranged in an array on the touch switch panel 101. By arranging the label icons in an array, the corresponding touch switches are also arranged accordingly, so that it can support more input data.

[0039] In a preferred embodiment, it also includes a rear shell 102, which is connected to the outer frame 103 and forms a space for accommodating the back of the touch switch panel 101 and the control circuit board; the rear shell 102 is provided with an external interface electrically connected to the interface connector 204 and the I / O port connector 205; the internal components are protected by the rear shell 102, and the rear shell 102 is made of plastic, for example, it can be made of engineering plastic to have good weather resistance and strength.

[0040] In a preferred embodiment, a jumper interface 203 is further provided on the above-mentioned circuit board, and the above-mentioned jumper interface 203 is electrically connected to the above-mentioned control chip 201. Since the control chip can store the parameters set in the device, the jumper interface 203 can be short-circuited to the ground to reset its parameters. For example, when a parameter failure occurs, the parameters can be cleared in this way and reset after power-on.

[0041] It should be noted that each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referred to each other.
