Example Embodiment

[0018] In order to deepen the understanding and understanding of the present invention, the present invention will be further described and introduced below with reference to the accompanying drawings.

[0019] like figure 1 As shown in the figure, a multi-functional composite key includes a functional composite key board and a key MCU board. The functional composite key board is provided with one or more keys and a knob adjustment key, and the key is connected to the input end of the key MCU board for output. The function type information of the key, the knob adjustment key is connected to the input terminal of the key MCU board, and is used to output the function status information of the key. The key control information is transmitted to the automotive electronic equipment for feedback processing. Specifically, the button MCU board is provided with a microcontroller and an A / D conversion module, the buttons and knob adjustment keys are connected to the I / O port of the micr...

Abstract

The invention relates to a multifunctional composite key, comprising a functional composite key panel, and a key MCU (microcontroller unit) board. The functional composite key panel is provided with one and more keys and one knob adjusting key; the keys are connected with the input end of the key MCU board and are used for outputting functional type information of the keys; the knob adjusting keyis connected with the input end of the key MCU board and is used for outputting functional state information of the keys; the output end of the key MCU board is connected with automotive electronic equipment and is used for generating key control information according to the acquired functional type information or functional state information and transmitting the information to the automotive electronic equipment for the purpose of feedback. The multifunctional composite key can use less mounting space of keys in a vehicle body, and manufacture cost and design cost of keys are effectively decreased.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a multifunctional compound key. Background technique [0002] At present, buttons are the main input devices for operating automotive electronic equipment, especially for automotive instrumentation, automotive air conditioners, and car entertainment display panels in the center console of automobiles. Each automotive electronic device in the existing automobile body room has a plurality of buttons, and each button has a single function and single operation, occupies more indoor space of the car body, increases the manufacturing cost of the automotive electronic device, and increases the The danger of the driver operating while driving. Therefore, in order to improve the ease of operation and safety of the automotive electronic equipment, it is necessary to improve the existing buttons of the automotive electronic equipment. Contents of the invention [0003] Th...
