An electrical switch with better operation experience and stronger science and technology sense has become one of the important directions for the development of intelligent automobiles.

In the current passenger car, the seat is used as an important component of human-vehicle interaction, and functions related to the seat are more and more intelligent and humanized. In particular, front row main and assistant seats, functions such as front-back up-down position adjustment of the seat, backrest angle adjustment, waist support adjustment, leg support adjustment, seat memory, seat ventilation, seat heating, seat massage, and the like.

For the above functions, the corresponding control switches are often dispersed in a plurality of different positions, for example, the switches for adjusting the front and rear up and down positions of the seat, adjusting the angle of the backrest, and adjusting the lumbar support are often located on the side of the seat, the switches for seat memory, seat massage, etc. are often located on the door trim or the side of the seat, and the switches for seat ventilation and seat heating are often located on the front instrument panel or the center tunnel sub-instrument panel.

For the existing forms of the switches, most of the switches are mechanical key type or mechanical toggle type, and in some vehicle types, some switches are made to be touch type, and are integrated in a central control touch large screen, or a touch area is arranged on an instrument panel or an auxiliary instrument panel, and a part of function touch keys related to a seat are placed at the same time of integrating other functions.

By way of example investigations it was found that:

1) most vehicles follow the traditional thinking of vehicle construction, and place a plurality of function control switches of the seat at several different positions, such as the switches of seat adjustment, backrest adjustment/waist support and the like on the side surface of the seat, the switches of seat memory and massage on the door, the switches of seat heating and seat ventilation and the like on the instrument panel/sub-instrument panel, so that the operation of users is relatively dispersed, the control areas of the same function are not concentrated, and the design logic of modern ergonomics is relatively not met.

2) Numerous seat functions still use a large number of mechanical switches, which are numerous, consume a lot of materials, and have a high cost. Each group of switches needs to be developed independently, the die is designed independently, the development cost, the die cost, the material cost, the manufacturing equipment cost and the labor cost are very high, the switch technological sense is low, the user experience is poor, and the development trend of the intelligent automobile is not met.

3) Especially, since the switches such as seat adjustment, backrest adjustment, and lumbar support, which are disposed at the side of the seat, are not visible to the user when the user gets on or off the vehicle, it is inconvenient for the new user to operate the switches.

4) For the existing touch switches in the current middle-high-grade vehicles, only the control switches of certain functions related to the seat are made into touch switches and integrated in a touch area in a central control touch large screen or arranged on an instrument panel or/and an auxiliary instrument panel, and the problems of switch dispersion, no concentration, material and area waste and the like are not solved essentially.

Fig. 6 discloses a structure diagram of a backlight assembly in a circuit board assembly of a touch type door trim according to an embodiment of the present invention. The backlight assembly 304 includes: a plurality of direct light sources (not shown), a plurality of light guide modules, and a plurality of light chamber modules. The direct light source is arranged on the circuit board and provides backlight for the operation beacons distributed on the operation panel in a scattered mode. The light guide module comprises a light source arranged on the circuit board and a light guide plate arranged above the light source, and the light guide module provides backlight for the small-area operation beacons densely distributed on the operation panel. The light chamber module is arranged on the circuit board and comprises a light chamber and a light source positioned at the bottom of the light chamber, and the light chamber module provides backlight for the large-area operation beacons which are densely distributed on the operation panel.

These LED lights are illuminated and may directly provide backlighting for the corresponding operating beacon. It should also be noted that the mode of providing backlighting may vary depending on the operational beacon. The modes of providing backlight include: the search light and the functional light.

The integral structure is embedded into the door trim panel.

The touch type car door interior trimming panel works and is used as follows:

taking a driver as an example, when the automobile enters a vehicle and is driven normally, the interior trimming panel of the automobile door has no feedback, and the backlight can not be lightened. When a driver prepares to use the related functions of the seat, the driver extends the hand to the area where the operation panel is located, when the distance between the hand and the operation panel is less than 5cm, the calibrated capacitance film sensor detects the action, the control unit in the circuit board assembly records the capacitance value change to be A, and sends a signal to control the lighting of a plurality of LED lamps (not shown) distributed on the surface of the circuit board, and the LEDs in the seat heating light chamber/the seat ventilation light chamber/the seat massage light chamber are also lighted, so that all the search light beacons are lighted. Similarly, when the distance between the hand and the plaque is less than 5cm, the search lights are all turned off.

When a user needs to use the function, for example, the seat back is adjusted, when the user needs to adjust the seat back backwards, the user only needs to touch the backrest backward tilting key with fingers, the corresponding backward tilting key sensing area on the back capacitive film sensor detects the action, the control unit in the circuit board assembly records the change of the capacitance value into B, and sends a signal to control the vibration electromagnetic valve to work, so that the vibration electromagnetic valve vibrates briefly, the finger vibration feedback is given to the user, the user is reminded that the triggering is successful, meanwhile, the signal is transmitted to the seat back adjustment controller through the connector and the corresponding wire harness (or the signal is transmitted to the gateway through LIN/CAN and then is transmitted to the seat back adjustment controller through the gateway), the seat back adjustment controller controls the corresponding motor to rotate, and the backward tilting adjustment of the seat back is realized. The user can adjust the backrest backward tilting key all the time by long pressing the backrest, and stop the backrest when the user loosens his hand. Other functions are adjusted similarly, and are not described in detail.

When a user needs to use the seat heating function, the user also only needs to touch the seat heating key by fingers, the corresponding seat heating key sensing area on the capacitive film sensor detects the action, the control unit in the circuit board assembly records the capacitance value change to be C, and sends a signal to control the vibration electromagnetic valve to work, so that the vibration electromagnetic valve vibrates temporarily, the finger vibration feedback is given to the user, and the user is reminded that the triggering is successful. And meanwhile, a signal is sent to light the LED lamp of the lowest light guide assembly in the three seat heating light guide assemblies, the light is conducted through the light guide plate, the function indicator lamp at the lowest part of the seat heating function indicator lamp is lightened, and a user is informed of first-gear heating (2/3 lamps are lightened to indicate second/third-gear heating, and the temperature of the third gear is highest). Meanwhile, a signal is sent to the seat heating controller through the connector and the corresponding wire harness (or the signal is sent to the gateway through the LIN/CAN and then is transferred to the seat heating controller through the gateway), and the seat heating controller controls the heating wires on the seat to work, so that the seat heating is realized. It should be noted that, here, the user only touches once and always touches, the effect is the same, the system only judges that this is one operation, only lights one function lamp, and starts the first heating; if 2 grades of heating are started, after the finger needs to be touched, the finger is removed and the finger is touched again, the second grade of heating is started, and 2 function indicating lamps are lightened. The same applies to the third gear. Touching 4 times means closing, i.e. forming 4 state cycles of first gear/second gear/third gear/closing.

The seat ventilation function and the seat heating are the same, and are not repeated.

The utility model discloses a board has integrateed touch seat function control assembly in the touch door on the interior plaque of door, with the seat relevant all function control integrated to a less touch panel on, makes seat function control button more concentrate, saves more mechanical type switch or machinery, touch-control combination switch.
