[0022] To enable those skilled in the art to better understand this solution, the technical solutions in the embodiments of this solution will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this solution, not all of them. Based on the embodiments of this solution, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this solution.
[0023] The term "comprising" and any other variations thereof in the specification, claims, and accompanying drawings of this invention mean "including but not limited to," and are intended to cover a non-exclusive inclusion, not limited to the examples listed herein. Furthermore, the terms "first" and "second," etc., are used to distinguish different objects, not to describe a specific order.
[0024] The implementation of this utility model will be described in detail below with reference to the accompanying drawings:
[0025] Please see Figures 1 to 3 A passenger-side electric air vent adjustment switch based on LIN bus, comprising:
[0026] A switch panel is installed on the passenger side. The switch panel includes a motorized air vent adjustment switch, which comprises M status switches that interact with the air conditioning controller, where M is a natural number greater than 0; wherein:
[0027] The electric air vent adjustment switch is connected to the air conditioning controller via a LIN bus, and the air conditioning controller is connected to the display via a CAN bus; the air conditioning controller is connected to the passenger-side left air vent adjustment motor and the passenger-side right air vent adjustment motor respectively; the passenger-side left air vent adjustment motor and the passenger-side right air vent adjustment motor are respectively connected to the air vent blades.
[0028] like Figure 2 and Figure 3 As shown, in this embodiment, the electric air outlet adjustment switch includes an air outlet up adjustment button 1, an air outlet down adjustment button 2, an air outlet left adjustment button 3, an air outlet right adjustment button 4, an air outlet left selection button 5, an air outlet right selection button 6, and an air outlet switch button 7.
[0029] In one specific implementation, the air vent selection button can be selected using a three-position rocker switch. The three-position rocker switch has three positions: pressing to the left position selects the left air vent on the passenger side, pressing to the right position selects the right air vent on the passenger side, and pressing to the middle position selects neither.
[0030] The air vent selection buttons are divided into a left air vent selection switch on the passenger side and a right air vent selection switch on the passenger side. The left air vent selection switch on the passenger side is used to control the working status of the left air vent adjustment motor on the passenger side, and the right air vent selection switch on the passenger side is used to control the working status of the right air vent adjustment motor on the passenger side.
[0031] The air outlet switch button is a lock-on switch. When the lock-on switch is turned on, the electric air outlet adjustment function is activated; when the lock-on switch is turned off, the electric air outlet adjustment function is deactivated.
[0032] The electric air vent adjustment switch is installed on the inside of the passenger-side door.
[0033] The left air vent adjustment motor on the passenger side and / or the right air vent adjustment motor on the passenger side are stepper motors.
[0034] The display is an IVI large screen.
[0035] The power supply is connected to the air conditioner controller via an LDO with model number ICW1261A120S3GQ1.
[0036] The model number of the air conditioner controller is FM33LE023A.
[0037] The electric air outlet adjustment switch has a LIN bus interface;
[0038] The air conditioner controller's drive motor is driven by a PWM motor, while the air outlet adjustment motor is a stepper motor.
[0039] The air outlet blades are connected to the air outlet adjustment motor, allowing for adjustment in all directions: up, down, left, and right.
[0040] To make it easier to clearly display the different buttons, a backlight 8 is installed on the switch panel;
[0041] To clearly display the working status of the air conditioner controller, the air conditioner controller is connected to a working indicator light 9.
[0042] When the air vent switch button is initially in the off position, the system disables the passenger-side air vent adjustment function and does not respond to the air vent selection and airflow direction adjustment commands of the air conditioning switch. When the air vent switch button is operated, the electric air vent adjustment switch sends an enable command for passenger-side air vent adjustment to the air conditioning controller via the LIN bus. The air conditioning controller controls the electric air vent to enter free mode and simultaneously sends feedback on its working status to the electric air vent adjustment switch and sends a feedback signal to the large screen IVI indicating that the air vent mode is free mode.
[0043] In free mode, each group of electric air outlet motors is independently controlled and is not affected by other groups. The working mode is selected through the IVI screen, and the direction is controlled by sliding. The stepper motor stops at the corresponding number of steps according to the sliding position. At the same time, if it is necessary to close the air outlet, touch the close button of the individual air outlet, and the horizontal motor rotates to the blade closed position, and the air damper is locked.
[0044] When the electric air outlet adjustment switch is enabled, the air conditioner controller receives a signal from the switch indicating that the air outlet selection switch is in the off state. At this time, the air conditioner controller will not respond to any air outlet adjustment signals sent by the switch, such as up, down, left, or right adjustment.
[0045] When the air vent selection switch is pressed to the left, the electric air vent adjustment switch sends a command to the air conditioning controller via the LIN bus to open the left air vent on the passenger side.
[0046] At this time, a short press of the air vent adjustment switch once will trigger the air conditioning controller to receive a valid air vent adjustment signal from the switch once, and then control the electric air vent damper on the left side of the passenger seat to be adjusted upward by 10%. A long press of the switch will continuously send adjustment signals, and the air conditioning controller will perform continuous actions.
[0047] A short press of the air vent lowering switch once will trigger a valid signal from the air conditioning controller, which will then lower the electric air vent damper on the passenger side by 10%. A long press of the switch will continuously send adjustment signals, and the air conditioning controller will perform continuous actions.
[0048] A short press of the air vent left adjustment switch once will trigger a valid left adjustment signal from the switch to the air conditioning controller, which will then adjust the left-side electric air vent damper of the passenger side by 10%. A long press of the switch will continuously send adjustment signals, and the air conditioning controller will perform continuous actions.
[0049] A short press of the air vent right adjustment switch once will trigger a valid right adjustment signal from the switch to the air conditioning controller, which will then adjust the electric air vent damper on the passenger side left side to the right by 10%. A long press of the switch will continuously send adjustment signals, and the air conditioning controller will perform continuous actions.
[0050] When the air vent selection switch is pressed to the right, the electric air vent adjustment switch sends a command to the air conditioning controller via the LIN bus to open the right air vent on the passenger side. At this time,
[0051] A short press of the air vent adjustment switch once will trigger a valid air vent adjustment signal from the switch to the air conditioning controller, which will then adjust the air vent damper on the passenger side left side by 10%. A long press of the switch will continuously send adjustment signals, and the air conditioning controller will perform continuous actions.
[0052] A short press of the air vent lowering switch once will trigger a valid signal from the air conditioning controller, which will then lower the electric air vent damper on the passenger side by 10%. A long press of the switch will continuously send adjustment signals, and the air conditioning controller will perform continuous actions.
[0053] A short press of the air vent left adjustment switch once will trigger a valid left adjustment signal from the switch to the air conditioning controller, which will then adjust the left-side electric air vent damper of the passenger side by 10%. A long press of the switch will continuously send adjustment signals, and the air conditioning controller will perform continuous actions.
[0054] A short press of the air vent right adjustment switch once will trigger a valid right adjustment signal from the switch to the air conditioning controller, which will then adjust the electric air vent damper on the passenger side left side to the right by 10%. A long press of the switch will continuously send adjustment signals, and the air conditioning controller will perform continuous actions.
[0055] When the air vent switch is turned off, the air conditioner controller receives a "closed" signal from the air vent adjustment switch. The air conditioner controller then controls the electric air vent to remain in free mode, while simultaneously sending a "closed" signal back to the air vent adjustment switch and a "free" signal back to the large screen IVI.
[0056] The above 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.
