[0001] The utility model relates to the technical field of automotive emergency starting devices, and particularly to an intelligent control box for automotive emergency starting. Background Art
[0002] With the continuous growth of the number of automobiles, the situation where vehicles cannot start due to battery power shortage occurs frequently, especially in winter at low temperatures, after long-term parking, or when the battery is aging. To address this problem, battery cable clamp devices equipped with emergency starting power supplies are widely used in the market. However, in the prior art, most battery starting devices have strong pertinence and usually only support one of the voltage types of 12V or 24V, and cannot achieve universal application.
[0003] In addition, existing starting devices mostly rely on users to manually judge the polarity connection, lacking effective reverse connection protection, short circuit protection, automatic identification, alarm prompt and other safety guarantee measures, having the risk of misoperation, and being difficult to meet the convenience and safety requirements of users in different vehicles and different usage environments.
[0004] Therefore, there is an urgent need for an automotive emergency starting device that can be compatible with 12V and 24V batteries and has intelligent judgment and multiple protection functions to improve the usage convenience and operation safety. Content of the Utility Model
[0005] In view of the above problems, the utility model provides an intelligent control box for automotive emergency starting, which can automatically identify the battery voltage type, provide protection functions such as reverse connection, short circuit, and undervoltage, has alarm prompt and key forced start control, improves the universality of the device and the safety of user use, and can effectively solve the problems in the background art.
[0006] To achieve the above object, the utility model provides the following technical solutions:
[0007] An intelligent control box for automotive emergency starting includes a central processing unit, an LDO voltage stabilization module, a high-power relay device, a reverse connection detection module, a cable clamp inspection module, an indicator light control module, a key detection module, and an alarm prompt sounding device, wherein:
[0008] The central processing unit is connected to the battery power supply through the LDO voltage stabilization module, and is respectively connected to the relay, the reverse connection detection module, the cable clamp inspection module, the indicator light control module, the key detection module, and the alarm prompt sounding device to achieve unified control;
[0009] The battery power supply is connected to the LDO voltage stabilization module, and provides a regulated power supply to the central processing unit through this voltage stabilization module;
[0010] The intelligent control box for car emergency start is equipped with a voltage detection unit, which includes a central processing unit, an LDO voltage regulator module, positive and negative battery input terminals, red alligator clips, and black alligator clips. The central processing unit can detect the input voltage. When the red and black alligator clips are clamped on the positive and negative terminals of the battery respectively, the central processing unit detects the battery input voltage and determines the power supply voltage and battery voltage status.
[0011] When the battery connector interface EC5 is connected to the battery power supply and the system starts up, the central processing unit (CPU) detects data sent from the wire clamp check, reverse input check, short circuit signal check, and undervoltage protection. The CPU provides this data to the CPU for judgment. If the signal is correctly judged, the CPU issues an instruction to drive the relay unit to connect and provide the voltage required for vehicle ignition. Otherwise, an alarm signal is issued, the error light flashes, and the relay output is blocked.
[0012] Preferably, the central processing unit can automatically identify whether the voltage level of the connected battery is 12V or 24V, and automatically adjust the output strategy based on the identification result.
[0013] Preferably, the button detection module includes a manual start button, which can be forcibly started by the central processing unit when the button triggering conditions are met.
[0014] Preferably, the indicator light control module is equipped with LEDs of different colors to indicate the start-up preparation state, fault state, and voltage state, respectively.
[0015] Preferably, the alarm prompting device is a buzzer, used to issue an audible prompt when abnormal conditions such as short circuit, reverse connection or startup failure are detected.
[0016] It has a voltage detection function and can automatically identify whether the connected battery is 12V or 24V. The central processing unit determines the voltage type based on the alligator clip connection status and decides whether to output a start signal.
[0017] When the wiring is correct, the voltage is reasonable, and there is no short circuit, the central processing unit controls the relay to close, thereby outputting the vehicle's ignition voltage. If abnormal signals such as reverse connection, short circuit, or undervoltage are detected, an alarm will be triggered by a buzzer and the fault indicator light will flash.
[0018] In addition, users can trigger the "force start" function through the button control module, allowing the central processing unit to bypass certain conditions and control the start-up under specific needs.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] 1. Enables automatic identification of 12V and 24V batteries, improving the versatility of the intelligent control box for car emergency start;
[0021] 2. Integrates reverse connection protection, short circuit protection, undervoltage protection, alarm prompts and other functions to improve the safety of the intelligent control box for emergency vehicle start-up;
[0022] 3. It adopts a unified control system with an intelligent central processing unit, which improves the accuracy of startup judgment and response speed;
[0023] 4. Add a button-based forced start function to enhance the emergency response capability of the intelligent control box for emergency vehicle start-up in special circumstances;
[0024] 5. The integrated structural design makes it easy for users to operate and is suitable for emergency starting of cars and trucks. Attached Figure Description

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example:
[0031] Please see Figures 1 to 2 This utility model provides a technical solution:
[0032] A smart control box for emergency car start-up, characterized in that it includes a central processing unit 10, an LDO voltage regulator module 30, a high-power relay device 50, a reverse connection detection module 70, a wire clamp inspection module 80, an indicator light control module 90, a button detection module 100, and an alarm sounding device BZ, wherein:
[0033] The central processing unit 10 is connected to the battery power supply 20 through the LDO voltage regulator module 30, and is also connected to the relay 50, the reverse connection detection module 70, the wire clamp inspection module 80, the indicator light control module 90, the button detection module 100, and the alarm prompt sound device BZ, respectively, to achieve unified control.
[0034] The battery power supply 20 is connected to the LDO voltage regulator module 30, and provides regulated power to the central processing unit 10 through the voltage regulator module;
[0035] Also includes:
[0036] The voltage detection unit includes a central processing unit 10, an LDO voltage regulator module 30, a battery positive input terminal 20-1, a battery negative input terminal 20-2, a red alligator clip 60-1, and a black alligator clip 60-2. The central processing unit 10 can detect the input voltage. When the red alligator clip 60-1 and the black alligator clip 60-2 are clamped on the positive and negative terminals of the battery respectively, the central processing unit 10 detects the battery input voltage and determines the power supply voltage and battery voltage status.
[0037] After the battery connector interface EC5 is connected to the battery power supply 20, the central processing unit 10 detects and judges the data sent by the wire clamp inspection module 80, the reverse connection detection module 70, the short circuit signal detection, and the undervoltage protection module. If the signal is correctly judged, the central processing unit 10 issues an instruction to drive the relay 50 to conduct and provide the voltage required for the car ignition. Otherwise, an alarm signal is issued, and the alarm prompt sound device BZ alarms. The error light is flashed by the indicator light control module 90, and the output of the relay 50 is blocked.
[0038] The central processing unit 10 can automatically identify whether the voltage level of the connected battery is 12V or 24V, and automatically adjust the output strategy based on the identification result.
[0039] The button detection module 100 includes a manual start button, which can be forcibly started by the central processing unit 10 when the button triggering conditions are met.
[0040] The indicator light control module 90 is equipped with LEDs of different colors to indicate the start-up preparation status, fault status, and voltage status, respectively.
[0041] The alarm prompting device BZ is a buzzer, used to issue an audible prompt when abnormal conditions such as short circuit, reverse connection or startup failure are detected.
[0042] In this application, the battery is connected to the control box via an EC5 interface. After the power input terminal 20 is connected to the battery, the input voltage is sent to the LDO voltage regulator module 30. The LDO voltage regulator module 30 stabilizes the input 12V or 24V DC voltage to 5V, providing a stable power supply to the central processing unit 10 and ensuring its stable operation.
[0043] After receiving power, the central processing unit 10 immediately acquires the voltage signal through the detection circuit connected to the alligator clips (red clip 60-1, black clip 60-2). The central processing unit 10 can automatically identify whether the currently connected battery is a 12V battery used in small passenger cars or a 24V battery used in heavy-duty vehicles such as trucks by judging the voltage magnitude (e.g., 12V ± threshold or 24V ± threshold).
[0044] At the same time, the central processing unit 10 combines the signal from the reverse connection detection module 70 to compare whether the voltage polarity of the red and black alligator clips is consistent with the preset value, thereby determining whether the connection is correct. If the positive and negative terminals are found to be reversed, an abnormal signal is sent to the alarm module BZ and the indicator light module 90 to issue an audible and visual prompt, and the relay does not conduct.
[0045] After the central processing unit 10 confirms that the alligator clips are connected correctly, the voltage is within a reasonable range, and there are no short circuits or reverse connection signals, the clip detection module 80 further confirms whether the alligator clips are in good contact with the battery (such as whether the contact resistance is too high). When all detection conditions are met, the central processing unit 10 outputs a control signal to drive the relay module 50 to close, thereby enabling the battery voltage to be output to the vehicle ignition system to realize the emergency start function.
[0046] The indicator module 90 is controlled by the central processing unit and has red, green, and yellow LEDs for indication.
[0047] Normal startup preparation complete (green light remains on);
[0048] The alligator clip is connected incorrectly or the polarity is reversed (red light flashing);
[0049] Abnormal voltage or loose clamp (yellow light flashing);
[0050] The alarm module BZ is a buzzer component that emits an alarm sound when it detects incorrect connection, startup failure, or other similar conditions to remind the user to check in time.
[0051] To enhance the applicability of the device, this utility model includes a button-based forced start function. The button detection module 100 is connected to the central processing unit 10. When the system detects a low voltage or abnormal wire clamp contact but the user still needs to force a start, the forced start logic can be manually triggered by pressing the button.
[0052] After receiving a forced start signal, the central processing unit 10 bypasses some abnormal judgment logic within a specific safety threshold and directly controls the relay module 50 to conduct, thereby realizing emergency start under special circumstances.
[0053] All the above functional modules are integrated into a single plastic casing, featuring excellent insulation and protection. The top of the casing houses operation buttons, status indicator lights, and an EC5 connector. Alligator clips connect to a cable that is heat-resistant and short-circuit resistant. The device is compact and portable. The circuit diagram for each part and the overall system is shown below. Figure 3 As shown.
[0054] This application is highly practical after it is applied, and the usage process can be simplified as follows:
[0055] 1. Connect this application to the vehicle's emergency jump starter via the EC5 interface;
[0056] 2. Connect the red and black alligator clips to the positive and negative terminals of the car battery, respectively;
[0057] 3. Check the indicator light status; a solid green light indicates that the machine is ready to start.
[0058] 4. If a red light flashes or a buzzer alarm sounds, please check if the polarity is reversed or if there is poor contact.
[0059] 5. If necessary, the “Force Start” button can be pressed to forcibly start the vehicle in the abnormal alarm state.
[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
