    摘要: An electronic lock includes an electric locking unit, a touch panel, and a control module. The control module stores a plurality of touch condition sets which are related to human contact. The control module executes an input scan operation on each touch switch of the touch panel, charges a self capacitor with a scan signal, and charges a mutual capacitor with a driving signal. The control module determines whether an electric change conforms with any one of the touch conditions. Through a structural design of the touch panel and a scan function design of the control module, the electronic lock can more accurately determine whether the touch panel is operated by human touch and can also normally operate in a humid environment.

    摘要: A membrane touch panel device includes a circuit board unit, a light-blocking frame plate, a plurality of light-blocking tabs, and an operation panel unit that are stacked along a front-rear direction. The circuit board unit includes a circuit board having a plurality of keypad circuits, and a plurality of LEDs being electrically connected to the circuit board. A light transmission rate of the circuit board ranges from 0% to 20%. The light-blocking frame plate is stacked on the circuit board, and defines a hollow section provided for the LEDs to protrude thereinto. The light-blocking tabs are connected to the light-blocking frame plate such that the light-blocking tabs respectively cover the LEDs. The operation panel unit is stacked on the light-blocking frame plate, and has a plurality of key segments being respectively aligned with the keypad circuits, and being adapted to permit light generated by the LEDs to pass therethrough.

    摘要: An electronic lock includes an input apparatus. The input apparatus includes a keypad module and a processor module. The keypad module includes plural button devices arranged in plural rows and in plural columns. The processor module includes a signal-processing unit configured to, when operating in a work mode, repeatedly perform an emission process of inputting a detection signal to each column of button devices, and repeatedly perform a scan process to detect, for each row of button devices, the detection signal outputted from any row of button devices. The detection signal includes a pulse wave composed of plural pulses. The signal-processing unit is further configured to generate and output an input signal corresponding to one of the button devices when detecting the detection signal.
