Description

Technical Field

[0001] The utility model relates to the field of automobile maintenance, and particularly relates to a power-off-free battery replacement connector for fuel vehicles. Background Art

[0002] After 3 to 5 years of use, the power storage capacity of the battery of a pure fuel vehicle will decline and needs to be replaced regularly. When replacing the battery, if there are no measures and the old battery on the vehicle is directly removed and then a new battery is installed, the entire vehicle will be completely powered off. Since the electronic control system of modern fuel vehicles is managed and controlled by different vehicle computers, such as instrument panel information, digital clock, ABS, ESP, memory seat, electric rearview mirror and many other electronic instruments. When the vehicle is completely powered off, the data stored in the computers of these electronic control systems may be lost. Once lost, it takes a lot of time to re-debug.

[0003] The technical solution is to provide a backup power supply path for the vehicle during the process of replacing the vehicle battery to enable the continuous operation of each vehicle computer and avoid the loss of data in the vehicle computer. The specific application method is to connect one end of the utility model to the backup power supply and insert the other end into the OBD16 diagnostic interface of the vehicle. After connection, "sound" and "light" elements will provide the connection status for the operator. When the LED lights up and the buzzer sounds simultaneously, it indicates that all components are connected normally. The operator can start the operation of replacing the battery. And when the operator removes the old battery on the vehicle, the backup power supply will continuously supply power to the vehicle computer, central control console, ABS computer and other units through the utility model, achieving the purpose of replacing the vehicle battery without power-off, and ensuring that the data stored in these computers will not be lost due to power-off. Content of the Utility Model

For this reason, the main purpose of the utility model is to provide a power-off-free battery replacement connector for fuel vehicles, aiming to solve the problem of the risk of data loss due to power-off when replacing the vehicle battery in the prior art.

[0005] To achieve the above purpose, the utility model provides a power-off-free battery replacement connector for fuel vehicles, including a connector main body composed of an external housing and an internal circuit component.

[0006] The internal circuit components include plug-in terminals and a power access position connected to one end of the plug-in terminals. The plug-in terminals include a signal ground terminal, a vehicle ground terminal, and a power terminal. The positive pole of the power access position is connected to the power terminal and the vehicle ground terminal, and the negative pole of the power access position is connected to the signal ground terminal. A buzzer, an LED, and a resistor are connected in parallel between the vehicle ground terminal and the power access position. One end of the buzzer is connected between the power terminal and the power access position. A reverse diode is provided between the other end of the LED and the signal ground terminal. The other end of the resistor is connected to the positive pole of the power access position.

[0007] One end of the external housing forms a connector for docking with a vehicle interface, and each of the plug-in terminals is located in the connector.

[0014] The beneficial effects of the present utility model are as follows: The power-off-free battery replacement connector for fuel vehicles proposed by the present utility model provides intuitive and accurate "sound" and "light" reminders, and there will be no misjudgment by operators due to operation steps. When the backup power supply is well connected and the vehicle end is not connected - the LED emits red light and the buzzer makes no sound. (It means: The backup power supply is normally connected and can be connected to the vehicle OBD port.) When the backup power supply is well connected and the vehicle end is also well connected, the LED red light is lit and the buzzer sounds at the same time. (It means: Both the backup power supply and the vehicle are normally connected, the backup power supply has started to supply power to the vehicle, the operator can start the operation of removing the old battery on the vehicle, and the vehicle will not experience a complete power outage.) When the vehicle end is well connected after the battery replacement is completed and the backup power supply is disconnected - the buzzer sounds and the LED emits blue light at the same time.

[0022] DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] As follows:

[0024] Please refer to the attached Figures 1-4 ,

[0025] The main structure includes a connector body 1 composed of an external housing 10 and an internal circuit component 2. The internal circuit component 2 includes a plug-in terminal 20 and a power access position 13 connected to one end of the plug-in terminal 20. The plug-in terminal 20 includes a signal ground terminal 200, a vehicle ground terminal 201, and a power terminal 202. The positive pole of the power access position 13 is connected to the power terminal 202 and the vehicle ground terminal, and the negative pole of the power access position 13 is connected to the signal ground terminal 200. A buzzer 22, an LED 21, and a resistor 23 are connected in parallel between the vehicle ground terminal and the power access position 13. One end of the buzzer 22 is connected between the power terminal 202 and the power access position 13. A reverse diode 24 is provided between the other end of the LED 21 and the signal ground terminal 200. The other end of the resistor 23 is connected to the positive pole of the power access position 13. One end of the external housing 10 forms a connector 12 for docking with a vehicle interface, and each plug-in terminal 20 is located in the connector 12.

[0026] The working principle is as follows:

[0027] It is mainly composed of components such as an OBD16 male head (plug-in terminal 20), a DC power supply port (power access position 13), a buzzer 22, a diode 24 (unidirectional conduction), a common anode light-emitting diode (LED 21), and a housing (external housing 10). Among them, the OBD16 male head is responsible for connecting to the OBD16 female head on the vehicle. The DC power supply port is connected to a backup power supply. The buzzer and the common anode light-emitting diode provide acoustic and optical prompts for the operator to clarify the operation timing.

[0028] After the DC power socket (power access position) is normally connected to the backup power supply, the current flows from the positive pole in the center of the DC port through a protection resistor (R) into the dual-color LED. Since the circuit between the cathode pin of the blue side of the LED and the negative pole of the DC port is disconnected by pins 4 and 5 on the OBD port, a loop cannot be formed and the blue LED core does not work. There is a reverse diode (D) between the cathode pin of the red side of the dual-color LED and pin 5 of the OBD port, which hinders the current from passing through. However, there is no obstacle between it and the negative pole of the DC port to form a complete loop with the DC port. Therefore, the red LED core starts to work and emits red light. The negative end of the buzzer does not form a loop with the circuit of the DC port because pins 4 and 5 are in an open state and will not work and remains silent. The current state is that the red light is constantly on and the buzzer does not sound, indicating that the connection to the backup power supply is normal.

[0029] When the DC power socket is properly connected to the backup power supply, after inserting this solution into the female OBD interface of the vehicle, since pins 4 and 5 of the vehicle-side OBD are conductive and conform to the current direction of D (reverse diode), the negative terminal of the buzzer is made conductive, forming a circuit with the DC port circuit, and the buzzer starts to work and make a sound. At this time, the state is that the red light remains constantly on, and at the same time the buzzer also makes a sound, indicating that both the backup power supply and the vehicle side are properly connected, and the operator can start removing the old battery on the vehicle.

[0030] After the old battery is removed, the backup power supply will continue to supply power to each vehicle computer on the vehicle body through the DC port (any other type of interface is acceptable), via pins 16 and 4 of the OBD port, to keep the data from being lost.

[0031] When the new battery is properly installed in the vehicle, disconnect the backup power supply from the DC port of this solution. At this time, the buzzer will obtain power from pin 16 of the vehicle OBD, and then form a circuit through pin 5 to continuously make a sound; the dual-color LED also obtains power from pin 16. The negative pin on the blue side forms a circuit through pin 5 to continuously emit blue light, while there is a reverse diode between the negative pin on the red side of the dual-color LED and pin 5 of the OBD interface, which blocks the current from passing through, and since the backup power supply has been removed, no circuit can be formed in both directions and it does not work; at this time, the state is that the buzzer continuously makes a sound and the LED emits blue light, indicating that the new battery has been properly installed.

[0032] The interface type can also be: cigarette lighter wire power supply, double-clamp wire power supply, and 12V switch power supply. When powered by the cigarette lighter wire, the power converter can be connected to the cigarette lighter interface of other vehicles through the cigarette lighter to supply power to the vehicle that needs to replace the storage battery; when powered by the double-clamp wire, the power converter can be connected to the backup power supply or to the storage battery of other vehicles through the double-clamp wire to supply power to the vehicle that needs to replace the storage battery; when powered by the 12V switch power supply, the power converter can be connected to the mains through the 12V switch power supply to supply power to the vehicle that needs to replace the storage battery.

[0033] A preferred embodiment of the present utility model: The power access position 13 is a pluggable interface.

[0034] It can be adapted to a variety of power supply sources, such as cigarette lighter wire power supply, double-clamp wire power supply, and 12V switch power supply, etc.

[0035] A preferred embodiment of the present utility model: The power access position 13 is a DC power interface structure.

[0036] The DC power interface is the preferred interface for this solution, with good adaptability and convenient plugging and use.

[0037] A preferred embodiment of the present utility model: The plug-in terminal 20 is a 16-pin terminal, and the power supply pin is on the 16th pin, and the signal ground terminal 200 and the vehicle ground terminal are on the 5th pin and the 4th pin respectively.

[0038] A preferred embodiment of the present utility model: The resistor 23 is an overvoltage protection resistor 23.

[0039] A preferred embodiment of the present utility model: The outer shell 10 is provided with a through hole 11 corresponding to the LED 21 on its surface.

[0040] A preferred embodiment of the present utility model: The LED 21 is a red and blue dual-color diode 24, and one end of the blue diode 24 is connected to the vehicle ground terminal, and one end of the red diode 24 is connected to the signal ground terminal 200 after passing through the diode 24.
