Description

Technical Field

[0001] This utility model relates to the technical field of portable power supplies, and in particular to a portable power supply with an integrated car ignition tube. Background Technology

[0002] With the widespread use of automobiles, car emergency power supplies, as important auxiliary equipment, provide starting power to help vehicles resume normal operation when they cannot start due to a dead battery or other reasons. Traditional car emergency power supplies typically connect to the car's power connector at one end via a battery clamp, and the other end connects to the corresponding port on the emergency power supply via a specific plug (such as an EC5 plug) to achieve power transmission. However, this traditional design has several shortcomings. First, using battery clamps for connection is cumbersome, especially in emergencies where poor contact or improper operation may result in failure to provide power. Second, existing car emergency power supplies are relatively simple in function, usually only providing ignition power, which is insufficient to meet users' needs for multi-functional integrated devices. Furthermore, traditional emergency power supplies are prone to performance degradation and even damage due to internal heat buildup during prolonged use; heat dissipation is a significant factor limiting their stability and lifespan. Therefore, developing a portable power supply device that is easy to operate, multifunctional, and has efficient heat dissipation has become an urgent technical challenge. Utility Model Content

[0003] The purpose of this invention is to provide a portable power supply with an integrated car ignition nozzle to overcome the shortcomings of existing technologies.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A portable power bank with an integrated automotive ignition outlet includes a housing. Inside the housing are a battery, an electronic control module, and a cooling fan. Externally, the housing is equipped with multiple functional interfaces and control switches to achieve various uses. Specifically: The housing has a Type-C first output port and a Type-C second output port on one side for transmitting electrical energy to external electronic devices; A USB input port is also provided on one side of the housing. This USB input port is electrically connected to the electronic control module. When an external power source is connected, the electronic control module can charge the battery and simultaneously supply power to other ports. A car ignition port is further provided on one side of the housing. The car ignition port is connected to the car battery via a connecting wire and is used to provide the ignition power required to start the car when the car is out of power. The top of the housing is equipped with a wireless charging coil, which is electrically connected to the electronic control module for contactless charging of electronic devices that support wireless charging. A positioning magnetic ring is arranged around the wireless charging coil. The positioning magnetic ring assists the electronic device in accurately aligning with the wireless charging coil through magnetic attraction, thereby improving charging efficiency and ease of use. A cooling fan is installed inside the housing. The cooling fan is electrically connected to the electronic control module. When the operating temperature of the equipment rises, the cooling fan starts and exhausts the heat from the air outlet on one side of the housing. An LED light is also provided on the outside of the housing. The LED light is electrically connected to the electronic control module and is used to display the remaining power status of the battery in real time. The exterior of the housing is equipped with an ignition switch, a wireless charging switch, and a data cable charging switch, which are used to control the working status of the ignition port, the wireless charging coil, and the Type-C first output port and the Type-C second output port, respectively.

[0005] Furthermore, the electronic control module, as the core control unit, is electrically connected to the battery, cooling fan, wireless charging coil, various functional interfaces, and switches to coordinate the working states of each component. The electronic control module embeds logic circuitry that selectively activates or deactivates corresponding output ports and functional modules based on the operation commands of each switch. For example, when a user presses the car ignition switch, the electronic control module detects the signal and activates the car ignition port, causing it to output sufficient current to start the car; when the user presses the wireless charging switch, the electronic control module triggers the wireless charging coil to enter working mode, beginning to charge the electronic devices placed on it.

[0006] Specifically, the cooling fan is designed with an axial flow structure, generating airflow through high-speed rotation to guide the heat accumulated inside the casing to the exhaust port. To improve heat dissipation efficiency, the exhaust port has a larger opening area than the inlet area, and guide vanes are installed at the exhaust port to reduce airflow resistance and enhance heat dissipation. Furthermore, the starting and stopping of the cooling fan is controlled by the electronic control module based on data from the temperature sensor inside the casing. When the internal temperature exceeds a preset threshold, the cooling fan automatically starts until the temperature drops to a safe range.

[0007] Furthermore, the wireless charging coil employs Qi-compliant electromagnetic induction technology, establishing an energy transmission channel with wireless charging-enabled devices through a high-frequency alternating magnetic field. The positioning magnetic ring is made of a high-permeability material, and its magnetic pole orientation is precisely designed to ensure that electronic devices can quickly align with the optimal charging position of the wireless charging coil. Additionally, the outer diameter of the positioning magnetic ring is slightly larger than the diameter of the wireless charging coil to ensure magnetic attraction while avoiding interference with wireless charging efficiency.

[0008] Furthermore, the LED light employs a low-power light-emitting diode array, displaying the remaining battery power through segmented illumination. Specifically, the LED light has four brightness levels, each corresponding to a 25% battery capacity range, allowing users to intuitively judge the current battery status based on the number of lit LEDs. The LED light's driving circuit includes a voltage regulator module to ensure stable brightness output even under fluctuating input voltage.

[0009] Furthermore, the battery is a lithium-ion battery pack, characterized by high energy density and long cycle life. Overcharge and over-discharge protection circuits are installed between the battery and the electronic control module to prevent damage caused by abnormal operation. The USB input port supports fast charging protocols; when an external power source conforming to fast charging standards is connected, the electronic control module identifies the protocol and adjusts the charging parameters to shorten charging time.

[0010] Furthermore, the ignition port is connected to the car battery via a dedicated connecting cable, with clamps and plugs at both ends to meet the needs of different car models. The ignition switch is designed as a mechanical button; the user must continuously press the button to maintain power to the ignition port, thus avoiding safety hazards caused by accidental activation.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By integrating a Type-C output port, a USB input port, a car ignition port, and a wireless charging coil, a single device can meet multiple power needs, significantly improving the product's practicality. The built-in cooling fan and air vent design effectively reduces the internal temperature of the equipment and extends its service life. The independent function switch allows users to flexibly select functions according to their actual needs, simplifying the operation process; The positioning magnetic ring around the wireless charging coil enables precise alignment of electronic devices, improving the efficiency of wireless charging and the user experience. The remaining battery level is displayed in real time via LED lights, making it easier for users to plan their usage time accordingly. With its compact and rationally laid-out structure, it combines portability and functionality, making it suitable for emergency power needs in various scenarios such as home and outdoor environments.

[0012] In summary, this utility model, through optimized internal structure and functional integration, provides a highly efficient, convenient, and stable portable power supply with an integrated car ignition nozzle, solving many problems existing in the prior art and possessing high market application value.

[0015] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings: like Figure 1-3 As shown, this embodiment provides a portable power bank with an integrated car ignition port. Its overall structure consists of internal components within a housing, as well as external interfaces and control switches. These components work together to achieve multi-functionality and high efficiency. The housing serves as the main frame of the device, supporting and protecting the internal components. One side has a Type-C first output port 1 and a Type-C second output port 2 for connecting external electronic devices such as mobile phones and tablets, providing power transmission support. Simultaneously, a USB input port 4 is located on one side of the housing and is electrically connected to the electronic control module 12. When connected to an external power source, the electronic control module 12 charges the battery 13 and simultaneously supplies power to other functional ports, ensuring a continuous power supply for the device. The car ignition port 3 is located on one side of the housing and is connected to the car battery via a dedicated cable. When the car cannot start due to a dead battery, this port can output a high current to provide the ignition power required for starting the car, addressing power needs in emergency situations.

[0016] The wireless charging coil 10 is mounted on the top of the housing and electrically connected to the electronic control module 12. A positioning magnetic ring 11 is arranged around it. The positioning magnetic ring 11 is made of a high-permeability material, and its magnetic pole direction is precisely designed so that when the user places a wirelessly charging-enabled electronic device on the wireless charging coil 10, it can quickly align to the optimal charging position through magnetic attraction, thereby improving charging efficiency and enhancing ease of use. The cooling fan 14 is installed inside the housing and its operation is controlled by the electronic control module 12. The air vent 8 is located on one side of the housing to dissipate internal heat, reducing the device's operating temperature and extending its lifespan. The LED light 9 is located outside the housing and electrically connected to the electronic control module 12. It uses a low-power LED array with segmented illumination to display the remaining battery power status of the battery 13. Users can intuitively judge the current battery level by the number of lit LEDs and rationally plan their usage time.

[0017] The exterior of the housing also features an ignition switch 5, a wireless charging switch 6, and a data cable charging switch 7, which are used to control the operating status of their respective functional modules. The ignition switch 5 uses a mechanical button design; the user must continuously press the button to maintain power supply to the ignition port 3, avoiding safety hazards caused by accidental activation. The wireless charging switch 6 triggers the wireless charging coil 10 to enter operating mode, while the data cable charging switch 7 activates the charging functions of Type-C first output port 1 and Type-C second output port 2. The electronic control module 12, as the core control unit, is electrically connected to the various functional interfaces and switches of the battery 13, cooling fan 14, and wireless charging coil 10, coordinating the operating status of each component. Embedded logic circuits selectively activate or deactivate corresponding output ports and functional modules based on switch operation commands.

[0018] In actual use, S1, the user first checks the LED light 9 to confirm whether the remaining power of the battery 13 is sufficient. If the power is insufficient, it can be charged by connecting an external power source through the USB input port 4. At this time, the electronic control module 12 detects the external power source and adjusts the charging parameters and starts the fast charging protocol to shorten the charging time. S2, when it is necessary to provide starting power for the car, the user inserts one end of the dedicated connection cable into the car ignition port 3 and the other end into the car battery. After pressing the car ignition switch 5, the electronic control module 12 receives the signal, activates the car ignition port 3, outputs a high current to drive the car to start, and releases the button to stop the power supply. S3, if the user needs to charge an electronic device that supports wireless charging, the device can be placed above the wireless charging coil 10. The positioning magnetic ring 11 uses magnetic attraction to help the device align with the best charging position. Then, the user presses the wireless charging switch 6, and the electronic control module 12 triggers the wireless charging coil 10 to enter the working state. The device establishes an energy transmission channel with the device through a high-frequency alternating magnetic field to complete the charging. For external devices that are charged via data cable, users can connect the device to Type-C first output port 1 or Type-C second output port 2, press the data cable charging switch 7, and activate the corresponding port using the electronic control module 12 to start charging the device.

[0019] The cooling fan 14 is designed with an axial flow structure, generating airflow through high-speed rotation to guide the heat accumulated inside the casing to the exhaust port 8 for discharge. To improve heat dissipation efficiency, the opening area of ​​the exhaust port 8 is larger than that of the inlet, and guide vanes are installed at the exhaust port 8 to reduce airflow resistance and enhance heat dissipation. The start and stop of the cooling fan 14 are controlled by the electronic control module 12 based on data from the temperature sensor inside the casing. When the internal temperature exceeds a preset threshold, the cooling fan 14 automatically starts until the temperature drops to a safe range. The battery 13 uses a lithium-ion battery pack, which features high energy density and long cycle life. Overcharge protection circuit and over-discharge protection circuit are installed between the battery 13 and the electronic control module 12 to prevent damage caused by abnormal operation.

[0020] In outdoor scenarios, the multifunctional design of this invention demonstrates significant advantages. For example, if a user encounters a car battery drain while on a road trip, they can directly use the car ignition port 3 to provide starting power without needing to carry additional traditional emergency starting equipment. Simultaneously, while camping, the wireless charging coil 10 can be used to charge mobile phones and other devices to meet daily power needs. Furthermore, the device's compact design makes it easy to carry and suitable for emergency power needs in various scenarios, including home and outdoor settings.

[0021] In summary, this utility model achieves efficient, convenient, and stable performance by integrating multiple functional interfaces, optimizing the internal structural design, and introducing intelligent control technology. It solves the problems of limited functionality, inconvenient operation, and poor heat dissipation in existing automotive emergency jump starters, thus possessing high market application value. The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as these combinations of technical features do not contradict each other, they should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
