Description

Technical Field

[0001] This utility model relates to the field of vehicle electronics technology, and in particular to a connector insertion device and a vehicle. Background Technology

[0002] With the continuous development of automotive electronics technology, the Electronic Control Unit (ECU) is the core component of the vehicle control system, responsible for processing various sensor signals and controlling actuator actions. The reliability of its connection with the vehicle has become particularly important.

[0003] Connectors, as core components of vehicle electrical systems, undertake crucial tasks such as sensor signal transmission, actuator control, and inter-system communication. For example, the connection between the ECU and components such as sensors and actuators is typically achieved through connectors. With the increasing intelligence of automobiles, the reliability of ECU connector connections directly affects the stability of engine control, safety systems (such as airbags), and driver assistance functions. For instance, poor connections may lead to signal attenuation, control command delays, or failures. If poor connector connections are not detected in time, they may cause misjudgments by safety systems or paralysis of critical functions, thereby affecting the personal safety of drivers and passengers. Utility Model Content

[0004] The purpose of this invention is to solve the problem of how to detect connector mis-connection. This invention provides a connector mating device that can detect whether the connector is properly mated, and can promptly identify mis-connection between the connector and the vehicle, thereby improving the reliability and safety of the connector connection.

[0005] To solve the above-mentioned technical problems, an embodiment of this utility model discloses a connector insertion device, comprising:

[0006] Control Department;

[0007] A display module is connected to the control unit;

[0008] The input detection module includes an input terminal, an output terminal, and a voltage biasing unit. The input terminal is used to receive a first electrical signal from the connector. The voltage biasing unit is connected in parallel between the input terminal and the output terminal to generate a second electrical signal. The output terminal is connected to the control unit and is used to output the second electrical signal or the first electrical signal to the control unit.

[0009] The display module is used to output first information corresponding to the first electrical signal, the first information indicating that the connector is normally inserted into the plugging device; or, the display module is used to output second information corresponding to the second electrical signal, the second information indicating that the connector is not normally inserted into the plugging device.

[0010] Using the above technical solution, when the output terminal outputs a first electrical signal to the control unit, the display module outputs first information, indicating that the connector is properly inserted into the mating device. When the output terminal outputs a second electrical signal to the control unit, the display module outputs second information, indicating that the connector is not properly inserted into the mating device, such as the connector being detached from the mating device or poor contact between the connector and the mating device. On the one hand, it can detect whether the connector is properly inserted in real time, promptly identify poor mating between the connector and the vehicle, promptly detect potential safety hazards, improve fault response speed, and thus improve the connection reliability and safety of the connector. On the other hand, since the above technical solution transmits and analyzes electrical signals, it can ensure the accuracy and reliability of detection at a relatively low cost.

[0011] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a connector insertion device, wherein the first electrical signal includes a low-level signal and the second electrical signal includes a high-level signal.

[0012] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a connector insertion device, including a power supply, wherein the voltage biasing unit includes a pull-up resistor for generating the high-level signal, one end of the pull-up resistor is connected to the power supply, and the other end is connected to the input terminal.

[0013] By adopting the above technical solution, when the connector is not properly inserted into the insertion device, a stable high-level state (i.e., generating a second electrical signal) is established between the input terminal and the power supply through the current limiting and clamping effect of the pull-up resistor, and the second electrical signal is output to the control unit through the output terminal. Therefore, it is possible to accurately and reliably detect whether the connector is properly inserted at a lower cost.

[0014] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a connector insertion device, wherein the pull-up resistor includes a first resistor and a second resistor arranged in series.

[0015] By adopting the above technical solution, the two series-connected first and second resistors can ensure the reliability of the voltage biasing unit. For example, if one of the resistors is short-circuited, causing a large instantaneous current, the voltage biasing unit can still work normally because the other resistor provides a safety net. That is, the above technical solution adopts a redundant circuit design to ensure that the voltage biasing unit and the entire plug-in device are safe and reliable enough.

[0016] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a connector insertion device, wherein the input detection module includes a current limiting resistor, one end of the current limiting resistor is connected to the other end of the pull-up resistor, and the other end of the current limiting resistor is connected to the output terminal.

[0017] Using the above technical solution, one end of the current-limiting resistor is connected to the other end of the pull-up resistor, and the other end of the current-limiting resistor is connected to the output terminal. This limits the amount of current flowing from the output terminal into the control unit, which can provide protection for the control unit and prevent excessive current from damaging it.

[0018] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a connector insertion device, wherein the input detection module includes a first capacitor and a second capacitor, one end of the first capacitor is disposed between the other end of the pull-up resistor and one end of the current limiting resistor, and the other end of the first capacitor is grounded, one end of the second capacitor is disposed between the other end of the current limiting resistor and the output terminal, and the other end of the second capacitor is grounded.

[0019] By adopting the above technical solution, the first capacitor and the second capacitor can filter noise of different frequencies, effectively suppress interference and improve immunity, thereby jointly achieving EMC (Electromagnetic Compatibility) protection.

[0020] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a connector insertion device, including a display module, which is connected to the control unit and is used to display the first information or the second information.

[0021] By adopting the above technical solution and setting up a display module, fault information can be provided to users or maintenance personnel more intuitively and conveniently, thereby improving the efficiency of troubleshooting.

[0022] According to another specific embodiment of the present invention, a connector insertion device is disclosed, wherein the display module includes any one of an indicator light, a display screen, and a buzzer.

[0023] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a connector insertion device, wherein the control unit includes a microcontroller.

[0024] This utility model also discloses a vehicle, the vehicle comprising:

[0025] The connector insertion device in any of the above embodiments;

[0026] The connector includes a detection terminal connected to the input terminal and grounded, for generating the first electrical signal.

[0027] By adopting the above technical solution, the connector insertion device can be integrated into existing vehicles without major modifications. Based on the fact that the connector insertion device can detect whether the connector is properly inserted in real time, it can promptly detect poor insertion between the connector and the vehicle, identify potential safety hazards in a timely manner, improve fault response speed, and thus improve the overall safety performance of the vehicle.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0042] In some embodiments, see Figure 1This application provides a vehicle including a connector insertion device and a connector. The connector includes a detection terminal connected to an input terminal 10. The detection terminal is grounded and used to generate a first electrical signal. Exemplarily, the detection terminal can be directly grounded (e.g., ...). Figure 1a (As shown), it can also be directly grounded through a 0Ω resistor (as shown). Figure 1b As shown in the figure, a low-impedance loop is formed, causing the voltage of the terminal to be pulled down to ground potential (low level). This application embodiment does not limit the number of detection terminals. In addition, this application embodiment does not limit the number of detection terminals, for example, it can be 1, 2, 3, 4, 5, 10, 15, etc.

[0043] For example, the connector is an ECU (Electronic Control Unit) connector. This application embodiment does not limit this, but it can be an EMS (Engine Management System) connector, a BCM (Body Control Module) connector, etc.

[0044] In some embodiments, see Figure 2 , Figure 3 , Figure 4 The connector insertion device includes a display module, a control unit, and an input detection module. The display module is connected to the control unit and displays either first or second information. The input detection module includes an input terminal 10, an output terminal 20, and a voltage biasing unit. The input terminal 10 receives a first electrical signal from the connector. The voltage biasing unit is connected in parallel between the input terminal 10 and the output terminal 20 to generate a second electrical signal. The output terminal 20 is connected to the control unit and outputs either the first or second electrical signal to the control unit. The display module outputs first information corresponding to the first electrical signal, indicating that the connector is properly inserted into the insertion device. Alternatively, the display module outputs second information corresponding to the second electrical signal, indicating that the connector is not properly inserted into the insertion device.

[0045] Using the above technical solution, when the output terminal 20 outputs a first electrical signal to the control unit, the control unit outputs first information, indicating that the connector is properly inserted into the mating device. When the output terminal 20 outputs a second electrical signal to the control unit, the control unit outputs second information, indicating that the connector is not properly inserted into the mating device, for example, the connector has come out of the mating device or the connector has poor contact with the mating device. On the one hand, it can detect whether the connector is properly inserted in real time, and can promptly detect poor mating between the connector and the vehicle, promptly identify potential safety hazards, improve fault response speed, and thus improve the connection reliability and safety of the connector. On the other hand, since the above technical solution transmits and analyzes electrical signals, it can ensure the accuracy and reliability of detection at a lower cost.

[0046] In some embodiments, see Figure 2 , Figure 3 , Figure 4 The control unit includes a signal processing module and a judgment logic module. The signal processing module is connected to the output terminal 20 and is used to perform analog-to-digital conversion and comparison processing on the electrical signal output from the output terminal 20 to extract valid insertion status information. The judgment logic module is connected to the signal processing module and is used to judge the processed signal according to a preset threshold or algorithm to determine the insertion status of the connector. For example, the control unit includes a microcontroller unit (MCU).

[0047] In some embodiments, see Figure 2 , Figure 3 , Figure 4 The display module includes any one of an indicator light, a display screen, and a buzzer. For example, a constantly lit indicator light indicates that the control unit outputs a second message, namely, the connector is not properly inserted into the plug-in device. A constantly lit indicator light indicates that the control unit outputs a first message, namely, the connector is properly inserted into the plug-in device. It is understood that this application embodiment does not limit the type of display module; for example, the first or second message may also be output in the form of a fault code. For example, the display module and the control unit are connected via CAN (Controller Area Network) communication.

[0048] In some embodiments, see Figure 2 , Figure 3 , Figure 5 and combined Figure 6The first electrical signal includes a low-level signal, and the second electrical signal includes a high-level signal. Exemplarily, the connector mating device includes a power supply (VCC), and the voltage biasing unit includes a pull-up resistor 30 for generating a high-level signal. One end of the pull-up resistor 30 is connected to the power supply, and the other end is connected to the input terminal 10. Exemplarily, when the connector is not inserted into the mating device or is poorly inserted, the circuit between the input terminal 10 and the detection terminal is broken. At this time, the input terminal 10 remains at a high level due to the pull-up resistor 30. When the connector is properly inserted into the mating device, the input terminal 10 can remain at a low level because the connector detection terminal is grounded.

[0049] For example, when the connector is normally inserted into the insertion device, the signal processing module can convert the first electrical signal output from the output terminal 20 into a low-level signal (0). After receiving the low-level signal, the judgment logic module determines that the connector is in a normal insertion state and outputs the first information. When the connector is not inserted into the insertion device or is poorly inserted, the signal processing module can convert the second electrical signal output from the output terminal 20 into a high-level signal (1). After receiving the high-level signal, the judgment logic module determines that the connector is in a normal insertion state and outputs the second information.

[0050] In some embodiments, see Figure 2 , Figure 3 , Figure 5 and combined Figure 6 The pull-up resistor 30 includes a first resistor 31 and a second resistor 32 connected in series. In some embodiments, the input detection module includes a current-limiting resistor 40, one end of which is connected to the other end of the pull-up resistor 30, and the other end of which is connected to the output terminal 20. Exemplarily, the resistance values ​​of the first resistor 31, the second resistor 32, and the current-limiting resistor 40 can be from 1kΩ to 10kΩ. It is understood that the embodiments of this application do not limit the resistance values ​​of the first resistor 31, the second resistor 32, and the current-limiting resistor 40, for example, they can be 1kΩ, 4.7kΩ, 5.1kΩ, 10kΩ, etc.

[0051] In some embodiments, see Figure 2 , Figure 3 , Figure 5 and combined Figure 6The input detection module includes a first capacitor 51 and a second capacitor 52. One end of the first capacitor 51 is located between the other end of the pull-up resistor 30 and one end of the current-limiting resistor 40, and the other end of the first capacitor 51 is grounded. One end of the second capacitor 52 is located between the other end of the current-limiting resistor 40 and the output terminal 20, and the other end of the second capacitor 52 is grounded. For example, the capacitance of the first capacitor 51 is 0.1μF, and the capacitance of the second capacitor 52 is 0.01μF. By connecting two capacitors with different capacitance values ​​(such as 0.1μF and 0.01μF) in parallel, noise of different frequencies can be filtered respectively. The larger capacitor has a better suppression effect on low-frequency noise (such as power supply ripple), while the smaller capacitor can quickly respond to high-frequency noise (such as spike interference from switching power supplies). It is understood that the embodiments of this application do not limit the capacitance values ​​of the first capacitor 51 and the second capacitor 52.

[0052] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
