[0030] Please see Figures 1 to 5This utility model provides an all-terrain vehicle in which multiple lights 02 are electrically connected to a power supply component and a light controller 01, respectively. Multiple lights 02 can be controlled by the light controller 01, which can more flexibly realize the control of the lighting system and improve the problem of relatively simple control of the existing all-terrain vehicle lighting system.

[0031] Please see Figure 3 This utility model relates to an all-terrain vehicle, comprising a vehicle body, a power supply assembly, a body controller, and a lighting system. The structure of the vehicle body is not limited and can refer to existing all-terrain vehicle body structures. The power supply assembly provides the necessary power to the lighting system. The power supply assembly includes, but is not limited to, the vehicle's battery, generator, or other battery management equipment, only needing to ensure that the lighting controller 01 and the lamps 02 receive sufficient power when needed. The body controller can refer to the structure and type of body controllers in existing all-terrain vehicles. The lighting system includes: a lighting controller 01 and multiple lamps 02. The lighting controller 01 is relatively independent of the body controller and is installed on the vehicle body. The installation method includes, but is not limited to, bolt connection. The lighting controller 01 is electrically connected to the power supply assembly. The lighting controller 01 is responsible for receiving instructions from the body controller and controlling each lamp 02 according to these instructions.

[0032] Multiple lamps 02 are installed on the vehicle body, and the installation methods include, but are not limited to, bolt connections, snap-fit ​​connections, etc. Each lamp 02 is electrically connected to a power supply component and a lighting controller 01. The lamps 02 are the execution parts of the lighting system; they can be the same or different. Multiple lamps 02 are installed in various locations on the vehicle. In this invention, the multiple lamps 02 are: left front combination lamp 021, right front combination lamp 022, front through lamp 023, roof center through lamp 024, roof side through lamps 025 / 026, left rear combination lamp 027, right rear combination lamp 028, and ambient light 029. In other embodiments, the multiple lamps may also include only a combination of the above-mentioned lamps. Each lamp 02 is electrically connected to the power supply component and the lighting controller 01 to receive power support and control signals. The lighting controller 01 and the body controller are electrically connected via CAN communication line 03. CAN communication, also known as Controller Area Network, is a serial communication protocol within a vehicle that can be used to connect various electronic control units of the vehicle. In the lighting system, the CAN communication line 03 between the lighting controller 01 and the body controller is used to transmit control commands and status information. CAN communication provides hardware support for the interaction between the lighting system and other systems controlled by the body controller (such as safety systems and navigation systems). The lighting controller 01 and the lamp 02 are electrically connected via LIN communication. LIN communication, also known as Local Interconnect Network, is a simple vehicle network protocol. In the lighting system, the LIN communication connection between the lighting controller 01 and the lamp 02 is used to transmit control signals. LIN communication is generally simpler and less expensive than CAN communication, and is suitable for controlling individual lamps or small lamp groups, offering high cost-effectiveness.

[0033] Please see Figure 3 and Figure 4In this utility model, the specific connection methods between the lighting controller 01 and the body controller via CAN communication and between the lighting controller 01 and the lamp 02 via LIN communication are not limited. In one embodiment of this utility model, the lighting controller 01 includes a CAN communication module (not shown) and a first LIN communication module (not shown). The CAN communication module is electrically connected to the body controller via a CAN communication line 03. Each lamp 02 includes a second LIN communication module 0201, a drive device 0202, and multiple LEDs 0203. The multiple LEDs 0203 are connected in parallel to the power supply component. The first LIN communication module is electrically connected to the second LIN communication module 0201. The second LIN communication module 0201 is electrically connected to the drive device 0202. The drive device 0202 is electrically connected to the multiple LEDs 0203 and controls the opening and closing of the multiple LEDs 0203 respectively. Specifically, in this embodiment, the power supply component includes a battery and an ON switch circuit 06 electrically connected to the battery. The positive terminals of multiple LED beads 0203 are connected to the 12V power supply line of the ON switch circuit 06, and the negative terminals of multiple LED beads 0203 are connected to the ground wire. The control terminals of the multiple LED beads 0203 are electrically connected to the drive device 0202. It should be noted that the CAN communication module can refer to the existing CAN communication module structure and can be obtained through general commercial means. The first LIN communication module and the second LIN communication module 0201 can also refer to the existing LIN communication module structure and can be obtained through general commercial means, and will not be described in detail here.

[0034] In one embodiment of this utility model, the drive device 0202 includes a self-test module. Specifically, in this embodiment, the self-test module includes voltage and / or current detection elements, which are installed in the circuit of the drive device and feed back the current and / or voltage in the circuit to the lighting controller 01. The lighting controller 01 includes a fault diagnosis module. The self-test module transmits current and / or voltage information to the fault diagnosis module through a first LIN communication module and a second LIN communication module 0201. The fault diagnosis module makes a diagnosis and transmits the diagnosis result to the body controller, thereby displaying it on the operating instrument panel. It should be noted that the method by which the fault diagnosis module determines the fault type based on whether the voltage and / or current meet the set threshold range in this utility model can refer to conventional detection methods in the vehicle field, and will not be elaborated here.

[0035] In one embodiment of this utility model, the power supply component includes a battery and an ON switch circuit 06 electrically connected to the battery. The positive terminal of the light controller 01 is electrically connected to the battery through a warning circuit 04, and the positive terminal of the light controller 01 is also electrically connected to the ON switch circuit 06 through a first wire 011. The negative terminal of the light controller 01 is electrically connected to a ground wire through a second wire 012. The positive terminal of the lamp 02 is electrically connected to the ON switch circuit 06, and the negative terminal of the lamp 02 is electrically connected to the ground wire. The driving device 0202 of the lamp 02 is electrically connected to the light controller 01. In this utility model, some of the lamps 02 also serve as warning lights. The warning lights and the driving device 0202 are also electrically connected to the battery through the light controller 01, the warning circuit 04, and form a constant power circuit. The lighting system also includes a combination switch 013 and a warning switch 05. The combination switch 013 is electrically connected to the ON switch circuit 06 and the light controller 01, and the warning switch 05 controls the on / off state of the warning circuit 04 between the light controller 01 and the battery.

[0036] It should be noted that in automotive electrical systems, the "ON position circuit" is controlled by the ignition switch state. It typically refers to the circuit that supplies power when the ignition switch is turned to the ON position. The ON position circuit provides battery power to all electrical components in the vehicle, including the circuits required to start the engine. "Constant power" (also known as BAT or KL30) is a stable power source drawn from the positive terminal of the battery and not controlled by any switch. It always has power and is used to power some critical electronic devices, such as the anti-theft controller and interior lights. In this embodiment, when the vehicle is not running, the warning lights are electrically connected to the battery through the lighting controller 01 to form a constant power circuit. This means that the warning lights can still operate when the vehicle is off, improving safety. Furthermore, in this embodiment, the design of the combination switch and the warning switch 05 allows the driver to flexibly control the lighting system as needed. The combination switch can control regular lights, while the warning switch 05 is specifically for controlling the warning lights, making operation more intuitive and convenient.

[0037] Considering that backlights 08 and indicator lights 07 are important components in automotive lighting systems, typically used to illuminate dashboards, control buttons, and displays, in one embodiment of this invention, the lighting system further includes backlights 08 and / or indicator lights 07, which are electrically connected to a lighting controller 01. Centralized management of the backlights 08 and / or indicator lights 07 by the lighting controller 01 enables unified control of interior lighting, improving operational convenience and user experience.

[0038] Please see Figure 5In one embodiment of this utility model, the all-terrain vehicle further includes a trailer (not shown), and a detachable connection part 09 is provided between the vehicle body and the trailer. As long as a reliable detachable connection between the vehicle body and the trailer can be achieved, this is sufficient. In this embodiment of the utility model, the connection part 09 includes a mechanical connection part and an electrical connection part. The electrical connection part includes a first terminal 091 disposed on the vehicle body and a second terminal 092 disposed on the trailer. The second terminal 092 is insulated from the metal shell of the trailer and electrically connected to the taillight of the trailer. The first terminal 091 is insulated from the vehicle body and electrically connected to the light controller 01. When the mechanical connection part is connected, the first terminal 091 and the second terminal 092 are correspondingly plugged in and electrically connected. In this embodiment, by designing the connection part 09 to combine the mechanical connection part and the electrical connection part, a robust connection method is provided, and a reliable electrical connection between the all-terrain vehicle and the trailer is ensured. This allows the all-terrain vehicle to control the taillight of the trailer through the light controller 01, improving the safety of nighttime driving.

[0039] The structure of the mechanical connection part in this invention is not limited; for example, it can be an existing conventional mechanical connection structure such as a hook structure. Preferably, please refer to... Figure 5 In one embodiment of this utility model, the mechanical connection part includes a hook hole 0931 and an elastic telescopic hook 0932. A first insulating shell 094 is provided outside the first terminal 091. The shape and structure of the first insulating shell 094 are not limited. A second insulating shell 095 is provided outside the second terminal 092. The shape and structure of the second insulating shell 095 are also not limited. A channel for inserting the first insulating shell 094 is provided on the second insulating shell 095. The shape of the channel is preferably such that it matches the first insulating shell 094 to facilitate the insertion of the first insulating shell 094. The hook hole 0931 is provided on the side wall of the channel and penetrates through the side wall of the channel. The elastic telescopic hook 0932 is correspondingly provided on the side wall of the first insulating shell 094. During the electrical connection of the first terminal 091 and the second terminal 092, the elastic telescopic hook 0932 is compressed and enters the hook hole 0931, and extends out under the action of the elastic element 0933 to hook onto the side wall of the hook hole 0931. The design of the elastic telescopic hook 0932 and the hook hole 0931 allows for rapid completion of electrical connections simultaneously with mechanical connections, facilitating quick deployment and disconnection. It should be noted that the elastic telescopic hook 0932 can also refer to existing elastic telescopic hook structures. In this embodiment, the elastic telescopic hook 0932 includes a hook portion 093 and an elastic element 0933. The hook portion 093 is slidably mounted onto the first insulating shell 094 along the through direction of the hook hole 0931. The elastic element 0933 includes, but is not limited to, a spring. The spring is disposed between the hook portion 093 and the first insulating shell 094, and compresses the hook portion 093 into the hook hole 0931 to contact the side wall of the hook hole 0931, thereby driving the trailer to move through the second insulating shell.

[0040] In this utility model, the types of multiple lamps 02 are not limited. In one embodiment, the multiple lamps 02 include various combinations of left front combination lamp 021, right front combination lamp 022, front through lamp 023, roof center through lamp 024, roof side through lamps 026 / 025, left rear combination lamp 027, right rear combination lamp 028, and ambient lamp 029. The positive terminal of each lamp 02 is electrically connected to the 12V line of the ON switch circuit 06, and the negative terminal of each lamp 02 is electrically connected to the ground wire. The positive terminals of the left front combination lamp 021, right front combination lamp 022, left rear combination lamp 027, and right rear combination lamp 028 are also simultaneously electrically connected to the constant power line from the battery for use as warning lights. This method allows the lamps 02 to have more functions, simplifies the number of hardware components, and improves hardware utilization. It should be noted that in circuit diagrams and circuit boards, GND usually represents the ground wire or 0 wire, which is the negative terminal of the battery. GND is not connected to actual ground, but is a hypothetical zero-potential reference point used to represent voltage relationships in a circuit.

[0041] In this all-terrain vehicle, multiple lights are electrically connected to a power supply component and a lighting controller, respectively. Individual lights can be controlled via the lighting controller, enabling more flexible control of the lighting system. Furthermore, the lighting controller is relatively independent from the vehicle body controller, reducing the load on the latter. The CAN communication connection between the lighting controller and the vehicle body controller increases transmission speed and communication reliability, while the low-speed, low-cost LIN communication between the lighting controller and the lights further reduces costs. This layered communication structure optimizes the lighting system, reduces costs, and improves the intelligence level of the all-terrain vehicle's lighting system. Therefore, this invention effectively overcomes some practical problems in the prior art, thus possessing high utilization value and practical significance.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
