Description

Technical Field

[0001] This utility model relates to the field of switch control equipment technology, specifically a switch control device for externally modified electrical appliances. Background Technology

[0002] With the increasing demand for travel, outings, and jungle treks, pickup trucks are being used in more diverse ways. Customers often opt to modify their vehicles to include headlights, spotlights, and heating systems to provide adequate illumination in low-light conditions and facilitate simple meals.

[0003] However, the current market mainly uses aftermarket electrical appliances for retrofitting headlights and dome lights on original vehicles, adding electrical appliances to the vehicle's exterior. These appliances are powered directly from the battery. In most cases, these external electrical appliances are used when the vehicle is not running. In this situation, the direct power supply from the battery can easily lead to low battery voltage, causing the car to fail to start the next time. Over time, repeated occurrences of low battery voltage and failure to start significantly shorten the battery's lifespan. Aftermarket electrical appliances have the disadvantages of simple modification methods and easy installation, but they also have limitations in use, low convenience, and difficulty in understanding their functional status. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a switch control device for externally modified electrical appliances, which solves the problems of limited modification methods, simple installation, usage restrictions, low ease of use, and difficulty in understanding the functional working status of aftermarket electrical appliances.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a switch control device for externally modified electrical appliances, comprising:

[0006] Body control module;

[0007] The main wiring harness connects to the vehicle control module.

[0008] There are multiple external power supply components that can be selected, and all of them are connected to the main line.

[0009] The external power supply components include:

[0010] The first connecting line is connected to the main line;

[0011] The second connection line has a power interface and a modification connector at each end;

[0012] A circuit breaker, which is connected to the first connection line and the second connection line;

[0013] A control switch is provided on the first connection line;

[0014] The vehicle body control module, in conjunction with the control switch, enables the circuit breaker to be switched on and off, thereby enabling the opening and closing of the retrofit connection port.

[0015] Preferably, the power interface is connected to the vehicle battery, and the modified connector is used for connecting external electrical appliances.

[0016] Preferably, a fuse is provided on the second connection line, and the fuse is located between the power interface and the circuit breaker.

[0017] Preferably, the main line is further connected to a winch power supply assembly, which includes:

[0018] The winch connects to the main line at one end;

[0019] The winch electromagnetic switch control terminal is connected to the other end of the winch connection line, and the winch electromagnetic switch control terminal is used to control the opening and closing state of the automobile winch.

[0020] A winch switch is installed on the winch connection line.

[0021] Preferably, the body control module is connected to an engine management system and an electronic braking system.

[0022] This utility model discloses a switch control device for externally modified electrical appliances, which has the following beneficial effects:

[0023] 1. When using the switch control device for the externally modified electrical appliance, the user first manually operates the control switch to send a command to the vehicle control module to open the external modification connection port. When the vehicle control module receives the opening command, it can combine the vehicle battery status and engine status to safely protect the use of the external electrical appliance and avoid excessive use of the battery, which could cause the vehicle to fail to start.

[0024] 2. The switch control device for this external electrical modification determines whether the vehicle's engine is currently in the OFF state. If it is in the OFF state, it further receives voltage signals to determine the current battery voltage and SOC value. If the voltage is ≥8V or the SOC value is ≥70%, the external electrical modification connection port operates normally, and the control switch illuminates the status indicator light upon receiving the feedback signal. If the voltage is <8V or the SOC value is <70%, the external electrical modification connection port cannot be opened, and the control switch indicator light will not illuminate. If the engine is not in the OFF state, the external electrical modification connection port operates normally, and the control switch illuminates the status indicator light upon receiving the feedback signal. When the external electrical appliance is in use, if the battery voltage drops below 8V or the SOC value drops below 70%, the vehicle control module will disconnect the circuit breaker control and simultaneously send a disconnection signal to the control switch, causing the status indicator light on the control switch to turn off.

[0033] According to the appendix Figure 1-2 As shown, it includes:

[0034] Body control module 1;

[0035] Main line 2, which is connected to body control module 1;

[0036] There are multiple external power supply components 3, and all of them are connected to the main line 2.

[0037] External power supply component 3 includes:

[0038] The first connecting line 31 is connected to the main line 2;

[0039] The second connection line 32 has a power interface 34 and a modification connector 35 connected to its two ends respectively;

[0040] Circuit breaker 33, which is connected to the first connecting line 31 and the second connecting line 32;

[0041] Control switch 36 is provided on the first connection line 31;

[0042] The vehicle body control module 1, in conjunction with the control switch 36, enables the circuit breaker 33 to be switched on and off, thereby enabling the modification connection port 35 to be opened and closed.

[0043] When in use, first manually operate the control switch 36 to send a command to the body control module 1 to open the external modification interface 35. When the body control module 1 receives the opening command, it can combine the vehicle battery status and engine status to safely protect the use of external electrical appliances and avoid excessive use of the battery, which may cause the vehicle to fail to start.

[0050] Furthermore, the body control module 1 is connected to the engine management system 5 and the electronic braking system 6.

[0051] The system determines whether the vehicle's engine is currently OFF. If it is OFF, it further receives voltage signals to determine the vehicle's battery voltage and SOC value. If the voltage is ≥8V or the SOC value is ≥70%, the external power conversion interface 35 operates normally, and the control switch 36 receives a feedback signal and illuminates the status indicator light. If the voltage is <8V or the SOC value is <70%, the external power conversion interface 35 cannot be opened, and the indicator light on the control switch 36 will not illuminate. If the engine is not OFF, the external power conversion interface 35 operates normally, and the control switch 36 receives a feedback signal and illuminates the status indicator light. When external electrical appliances are in use, if the battery voltage is lower than 8V or the SOC value is lower than 70%, the vehicle control module 1 will disconnect the circuit breaker 33 and simultaneously send a disconnection signal to the control switch 36, causing the status indicator light on the control switch 36 to turn off.
