Description

Technical Field

[0001] This utility model belongs to the field of automotive lighting control, and specifically relates to a button control system for automotive modified lighting. Background Technology

[0002] In terms of existing automotive aftermarket light modification and control, the modified lights have multiple functions and complex wiring. Generally, wiring harnesses and control boxes are used for wiring and control. However, both of these control methods require a tedious wiring process involving numerous power and signal lines, resulting in high modification costs and a large workload. Furthermore, existing wired control boxes can generally only be matched one-to-one with specific dedicated lights, or can only control the on / off state of the lights, thus limiting the multi-functional operation and control of the lights. Utility Model Content

[0003] The purpose of this invention is to provide a vehicle light button control system based on Bluetooth communication, which solves the problem that the vehicle light modification control box can only be matched with special vehicle lights or can only control the power on and off status of the vehicle lights.

[0004] A vehicle light button control system based on Bluetooth communication, characterized in that it includes a control box and Bluetooth vehicle lights; The control box includes a Bluetooth module, a button control module, a button predefined module, and an MCU control module; The Bluetooth module is connected to the Bluetooth vehicle light signal; The button control module and the button predefined module are respectively connected to the MCU control module; The button control module issues different control commands through different buttons or different combinations of buttons; The button predefined module allows for custom settings of the functions of multiple buttons; The MCU control module sends corresponding control signals to the Bluetooth vehicle lights according to the control commands from the button control module, and feeds back the working status of the Bluetooth vehicle lights to the MCU control module.

[0005] The MCU control module, Bluetooth module, and Bluetooth vehicle lights form an internal wireless network. The control system also includes a packet module, which connects to the Bluetooth vehicle light signals distributed in different areas through the internal wireless network.

[0006] Furthermore, the internal wireless network is a MESH network.

[0007] The Bluetooth vehicle lights are one or more of the following: driving lights, strip lights, headlights, warning lights, and work lights.

[0008] The Bluetooth headlights are connected via a signal.

[0009] Preferably, the control system further includes a vehicle headlight signal detection box connected to the original vehicle's CAN bus. The original vehicle headlight signal detection box is connected to the Bluetooth module and is used to detect the switching signal of the original vehicle headlights and feed it back to the MCU control module.

[0010] The control system also includes a Bluetooth wiring harness control box for controlling ordinary vehicle lights. The Bluetooth wiring harness control box is connected to the Bluetooth module and is used to input control signals from the MCU control module and the on / off signals of the original vehicle lights. It also outputs control signals and drives the working state of the ordinary vehicle lights through the wiring harness relay.

[0011] The beneficial effects of this utility model are: (1) The physical signal line controlling the headlights is replaced by Bluetooth signal, and the control buttons are replaced by the touch screen of the mobile terminal. The modified headlights only need to be connected to the power line, and no longer need to be connected to the signal line, which saves the wiring cost of the headlights themselves and eliminates the need for external wiring groups or control boxes; secondly, when assembling them on the original vehicle, the wiring process of physical wires is eliminated, saving wiring costs and improving the efficiency of headlight modification. (2) It contains physical buttons, but compared with the existing wired control box, these physical buttons have the functions of predefined buttons. In this way, by customizing the buttons, they can be bound to all Bluetooth car lights, and the functions of the buttons can be predefined by the user, thereby controlling all the Bluetooth car lights bound to them. The number of Bluetooth car lights required can be selected and they can be freely combined and used. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of a vehicle light button control system based on Bluetooth communication according to this utility model. Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings.

[0014] like Figure 1 As shown, the Bluetooth-based vehicle light button control system includes a control box 1, a Bluetooth vehicle light 8, a group module 6, an original vehicle light signal detection box 9, and a Bluetooth cable group control box 10.

[0015] The control box 1 is preferably a control panel installed on the original vehicle's center console. It includes a Bluetooth module 7, a button control module 3, a button predefined module 4, and an MCU control module 5. The button control module 3 and the button predefined module 4 are respectively connected to the MCU control module 5. The control box 1 is powered by a power module 2. The Bluetooth module 7 is connected to the Bluetooth headlights 8 via Bluetooth signals. The MCU control module 5, Bluetooth module 7, and Bluetooth headlights 8 form an internal wireless network, which is preferably a MESH network. The Bluetooth headlights 8 are one or more of the following: driving lights, strip lights, headlights, warning lights, and work lights. Preferably, they are driving lights, strip lights, headlights, warning lights, and work lights distributed in different areas. The grouping module 6 is connected to all Bluetooth headlights 8 via the internal wireless network.

[0016] The button control module 3 issues different control commands through different buttons or combinations of buttons; the button predefined module 4 allows for customized settings of the functions of multiple buttons. The MCU control module 5 sends corresponding control signals to the Bluetooth vehicle light 8 according to the control commands from the button control module 3, and also feeds back the operating status of the Bluetooth vehicle light 8 to the MCU control module 5. Specifically, the MCU control module 5 receives the Bluetooth signals fed back from the Bluetooth vehicle light 8, and then sends control signals to the Bluetooth vehicle light 8 to control its various functions. The various Bluetooth vehicle lights 8 also connect and exchange signals via Bluetooth signals, thereby enhancing signal strength and stability.

[0017] The core circuit of the original vehicle headlight signal detection box 9 is the original vehicle electronic signal detection and control module. It is mainly used to collect original vehicle driving status signals (such as brake, high beam, left turn, right turn, front fog lights, rear fog lights, etc.), control the original vehicle lighting equipment, and communicate with other vehicle units via serial port. It also provides stable power supply and status indication. The original vehicle headlight signal detection box 9 communicates via the original vehicle CAN bus and is connected to the Bluetooth module 7. It detects the on / off signals of the original vehicle headlights and feeds them back to the MCU control module 5. These on / off signals include the high beam on / off signal, turn signal on / off signal, etc., and are fed back to the MCU control module 5 via Bluetooth. For example, after the MCU control module 5 detects this signal, it adds this signal to a specific group of high beams controlled by a certain button. Once added and bound, the high beam function of control box 1 will be restricted by this signal. The high beam function of control box 1 can only be activated when the original vehicle high beams are on; otherwise, the high beam function button on control box 1 will be disabled. Specifically, the original vehicle headlight signal detection box 9 detects the voltage and transmits the voltage signal to the MCU control module 5. In the low voltage state, the MCU control module 5 sends a control signal to the warning light, causing the warning light to flash as an alarm.

[0018] The Bluetooth wiring harness control box 10 is connected to the Bluetooth module 7. The Bluetooth wiring harness control box 10 is used to control the ordinary vehicle lights 12 without Bluetooth function. It inputs the control signal from the MCU control module 5 and the switch signal from the original vehicle lights, and outputs the control signal and drives the ordinary vehicle lights 12 to work through the wiring harness relay 11.

[0019] The following is the scheme and control logic for customizing button functions: plan On the control box, several main control buttons are set to control various functions of the Bluetooth car lights, and three auxiliary small buttons are set to predefine the functions of the main control buttons.

[0020] (1) Number of buttons on the front: 4-12, used to control the normal operation of the Bluetooth car lights, represented by numbers 1-12; (2) Number of side buttons: 3, used for preset button functions, represented by ac.

[0021] II. Button Functions Key AC: a: Scan Bluetooth lights b: Function switch button c: Lock key III. Key Predefined Operation Steps 1. Bluetooth connection (1) The control box and Bluetooth headlights are both powered on. At this time, the Bluetooth headlights are not connected to the control box, and the main headlights are always on.

[0022] (2) Press button A. The control box will start scanning for Bluetooth car lights. The backlight of button A will flash green quickly. After scanning all Bluetooth car lights, the backlight will flash green slowly. At this time, press and hold button A for more than 5 seconds to group the Bluetooth car lights together, and then the backlight will stay on.

[0023] (3) After the Bluetooth headlights are connected to the control box, the main lights will turn off. After grouping, all functions are merged and deduplicated.

[0024] 2. Light function preset button (1) Press button b, the main light will turn on, and the green backlight of this button will flash slowly, indicating that the main light button preset state has been entered. At this time, press and hold any one of the buttons 1-12 for 3-7 seconds, and this button can be bound to the main light switch. The backlights of the main light and the bound button will flash slowly three times, and the backlight of button b will enter the constant light state.

[0025] (2) Press the b button again to switch the Bluetooth headlights to the next function (the function order is: main headlight high beam, main headlight low beam, reversing light, warning light, position light white, position light yellow, position light red. Among them, the main headlights of driving lights, strip lights, and work lights are all regarded as main headlight high beams. Turn signals, brake lights, driving lights, etc. do not need to be controlled by the control box, but need to be reserved in the program architecture). Press and hold any of the unbound buttons in 1-12 again to bind this button to this function.

[0026] The above method can be repeated to bind all functions to the button. If the same button is repeatedly bound to multiple functions, the latest binding will be used, and the previous bindings will be automatically removed.

[0027] 3. Switching between high and low brightness for main lights, high and low brightness for warning lights, and switching between synchronous and asynchronous functions for warning lights.

[0028] Bluetooth headlights and control box provide two-way feedback. When the main light and warning light functions are activated, and the main light has E-BOOST function, the main light needs to provide feedback to the control panel (merging and deduplicating, only one main light in the same light has this function, so it can enter the E-BOOST button preset or warning light high / low brightness and synchronous / asynchronous function switching preset).

[0029] (1) Similarly, button b, a short press enters the preset state of the switch button, a long press for 3-7 seconds enters the preset state of main light high / low brightness, warning light high / low brightness, or synchronous / asynchronous; a long press for 10-15 seconds enters the preset state of main light color temperature adjustment / warning light flashing mode / position light dynamic mode, etc. When entering different preset states, the flashing frequency of the backlight of button b is different, and after the button is bound, the flashing frequency of the main backlight and main light of the button is also different (four modes, namely slow flash, fast flash, super fast flash, and constant light). (2) Press and hold for 3-7 seconds to enter the high / low brightness / dimming function preset button state. At this time, press and hold one of the buttons 1-12 to bind this button as the high / low brightness switch (the previously bound switch will still be effective). For lamps with dimming function, the dimming level is determined by the lamp itself. After binding, if it is a white light, it will automatically exit the preset, and the backlight of button b will be constantly on. If it is an alarm lamp with synchronous / asynchronous function, it will exit the high / low brightness preset. At this time, press and hold button b again for 3-7 seconds to enter the synchronous / asynchronous function preset. Perform the same operation to bind the synchronous / asynchronous function switching button.

[0030] (3) Press and hold button b for 10-15 seconds to enter the preset button for switching between flashing mode and white light color temperature adjustment. At this time, the backlight of button b flashes very fast. Press and hold any one of the buttons 1-12 to bind the next mode switch. The light will automatically switch to the next mode, and the button will flash very fast at the same time. It will turn off after 3 seconds. Press any one of the buttons 1-12 again to bind the previous mode switch. The light will automatically switch to the previous mode, and the button will flash very fast again. It will turn off after 3 seconds. The flashing mode binding is complete, and the backlight of button b returns to constant light.

[0031] (4) Warning light / position light / white light color temperature adjustment reset function: Double-click the "Previous mode" button to reset to the original mode. The original mode is set by the factory.

[0032] (5) High / low brightness or brightness adjustment reset function: For lamps with brightness adjustment, double-clicking the high / low brightness switch button can restore the highest brightness mode.

[0033] 4. Lock and unlock (1) Lock After setting the function presets for a group of lights, press and hold the C button for 3-7 seconds to lock the button presets for that group. Once locked, these buttons and the functions of that group of lights are completely bound and cannot be changed unless unlocked. The C button backlight will flash slowly for three seconds and then turn off. (2) Unlock With any function of any light in any group on, press and hold the C button for 10-15 seconds to unlock it. The C button backlight will flash rapidly for three seconds and then turn off. 5. Button backlight color (1) The side buttons are backlit in green; (1) The front backlight is RGB LED beads. The color of the backlight of the button must be consistent with the color of the LED it is bound to. When working, it must also be consistent with the flashing mode of the LED, but they do not need to be synchronized.

[0034] Based on the above logic, users can easily predefine button functions, freely combine and group the Bluetooth car lights according to their needs, and assign various function buttons to each group to achieve the control purpose.
