Description
Technical Field
[0001] This utility model relates to the field of vehicle charging equipment technology, and in particular to a multi-functional vehicle charger. Background Technology
[0002] As an on-board power conversion device, the core function of a vehicle charger is to obtain power from the vehicle's cigarette lighter socket and provide charging services for mobile terminal devices (such as smartphones and tablets). For example, many ride-hailing vehicles have low configurations, with insufficient rear charging ports, making it difficult for passengers to recharge their devices. Furthermore, the proportion of passengers carrying charging equipment on short trips is relatively low, highlighting the urgent need for standardized power supply facilities to improve the service experience. When on-board chargers are used in ride-hailing vehicles, they can provide charging services for passengers' mobile phones, effectively reducing passengers' battery anxiety.
[0003] When on-board chargers are used in ride-hailing vehicles, for the convenience of passengers, the charger body is generally located near the rear seats, such as behind the headrests of a row of seats. One end of the charger body is connected to the vehicle's cigarette lighter to draw power, and the other end is equipped with a charging cable to provide charging for passengers.
[0004] However, traditional car chargers have limited functionality, leading to a poor user experience. For example: 1. They cannot detect the presence of passengers in the vehicle. Even when there are no passengers and the charger is not in use, it still operates at full power, resulting in excessive static power consumption (typical value > 0.5W) and wasting vehicle power resources. 2. They lack notification functions. Firstly, passengers may not know that they can charge their phones using this car charger. Secondly, after charging, passengers may forget to take their phones when they get off the vehicle, requiring extra effort to find or return them, severely impacting the user experience. 3. Car chargers need to display promotional content and change it periodically. Traditionally, this involves sticking promotional leaflets to the charger body. When the content needs to be changed, the leaflet must be peeled off and re-attached, which not only leaves glue residue on the body but also damages or reduces the stickiness of the leaflet, hindering reuse and resulting in a poor overall user experience. 4. They only support wired charging. With technological advancements, more and more mobile phones support wireless charging, which undoubtedly limits the applicable scenarios for car chargers.
[0005] Therefore, how to provide a multi-functional vehicle charger that enhances the functionality of the vehicle charger and thus improves the user experience has become an urgent technical problem to be solved. Summary of the Invention

[0052] The advantages of this utility model are:
[0053] 1. The system consists of a power supply module, a spring wire, a vehicle mount, a charging module, and a charging cable, all connected sequentially. The charging module is mounted on the vehicle mount and includes a human body sensor, a speaker, a display screen, and a wireless charging coil. The charging module's mainboard detects the presence of a person via the human body sensor and triggers the speaker to play a preset audio prompt, such as a reminder to use the vehicle charger or if a phone has been left behind. The human body sensor automatically detects the user's approach, triggering automatic wake-up or energy-saving sleep mode to reduce standby power consumption. The display screen can show promotional content as needed, eliminating the need for manually tearing and pasting promotional leaflets. The charging cable and wireless charging coil enable dual-mode charging to meet different passenger charging needs, significantly enhancing the functionality of the vehicle charger and thus greatly improving the user experience.
[0054] 2. By setting up an NFC reader / writer, a human body sensor, a light, and a QR code sign, the car charger can directly interact with a mobile phone equipped with an NFC tag via the NFC reader / writer, enabling one-touch connection. This eliminates the need to open the camera to scan and navigate. Alternatively, users can scan the QR code on the sign according to their personal preferences. When the charging motherboard detects the presence of a passenger via the human body sensor and the ambient light sensor detects that the ambient light brightness is below a preset brightness threshold, it automatically turns on the light to illuminate the QR code sign, improving the recognition success rate. Furthermore, the QR code sign is more resistant to mechanical wear and UV degradation than traditional QR code stickers, greatly improving the convenience, flexibility, efficiency, and durability of the car charger.
[0055] 3. By setting up a camera, it can serve as a supplementary camera for the vehicle to record driving logs, further enhancing the functionality of the onboard charger.
[0056] 4. By adding two additional USB-A ports on the power module, the charging needs of multiple devices can be met; by setting up dual USB-C + Lightning ports on the charging cable, the interface standards of mainstream devices can be covered, reducing the need for adapters and greatly improving the user experience.
[0057] 5. By setting a temperature sensor to monitor the temperature of the car charger, the charging power can be reduced or charging can be stopped when the temperature is too high, thus greatly improving the safety of the car charger.
[0058] 6. By integrating the communication module and the locator, remote status monitoring and location tracking functions can be achieved.
[0059] 7. By integrating a light into the camera, the pain point of inconvenient charging at night is solved. The light brightness can be intelligently adjusted according to the human body sensor signal, taking into account both practicality and atmosphere.
[0060] 8. By setting clips and threaded fasteners on the vehicle mount, the installation method of the vehicle mount can be flexibly selected. For example, the vehicle mount can be clamped to the headrest vertical bar of the first row of seats in the vehicle, or the elastic band can be threaded through the rear end of the threaded fastener and locked onto the headrest of the first row of seats for installation, which greatly improves the applicability. By setting a cable winding groove on the vehicle mount, it is easy to store the charging cable, which further enhances the functionality of the vehicle charger.
[0061] 9. By setting a winding groove in the middle of the support rod, the charging cable can be easily wound up and stored, avoiding random placement of the charging cable and greatly improving the user experience.
[0062] 10. The combination structure of the ball joint and the support rod supports 360° rotation, adapting to different installation environments and usage requirements.
[0063] 11. By setting the support plate as a metal support plate and setting a magnetic iron sheet on the outside of the charging housing of the charging module, the charging module can be magnetically attracted to the support plate by the magnetic iron sheet. Combined with the positioning groove set in the support plate, it can be quickly positioned, taking into account the convenience of picking up the charging module and the stability of its placement. In addition, the metal support plate can effectively improve the heat dissipation performance.
[0064] 12. By setting the support plate as a rounded rectangle, the safety of the vehicle mount is effectively improved.
[0065] 13. By setting the inner side of the limiting component to be arc-shaped, it can better fit the charging module, thereby providing safety protection for the charging module.
[0066] 14. By setting a handle on one side of the clamp and several anti-slip protrusions on the other side, the clamp can be opened and closed easily, which greatly improves the convenience of assembling and disassembling the vehicle mount.
[0067] 15. By incorporating spring wires, cable tangling can be avoided, effectively improving storage convenience. They are also tensile and bend-resistant, making them suitable for complex wiring scenarios inside vehicles.
[0068] 16. By setting up a silicone protective sleeve, the bending stress of the wire is effectively relieved, and the wire ends are protected from wear. It is especially suitable for high-vibration conditions in the vehicle environment, thereby greatly improving the durability of the vehicle charger.
[0069] 17. The separate design of the power supply module and the charging module allows for independent replacement or upgrade of components, reducing maintenance costs.
[0070] 18. By setting male buckles and slots on the display mounting parts, and having several female buckles in the inner ring of the display mounting slot, the display mounting parts can be flexibly disassembled and assembled through the male buckles, female buckles, and slots, thereby greatly improving the user experience.
[0071] 19. By setting charging cable mounting holes in the charging housing, a cable clip cover is attached to the charging housing through screw holes and embedded in the charging cable mounting holes. The first Type-C male connector of the charging cable is connected to the Type-C female connector inside the charging housing through the wire hole of the cable clip cover. That is, the cable clip cover limits and fixes the first Type-C male connector of the charging cable. When the charging cable is damaged and needs to be replaced, simply unscrew the screw in the screw hole to remove the cable clip cover, and the charging cable can be quickly replaced without having to mail it back to the manufacturer for repair as in the past, thus greatly improving the convenience of car charger repair.

[0142] In summary, the advantages of this utility model are as follows:
[0143] 1. The system consists of a power supply module, a spring wire, a vehicle mount, a charging module, and a charging cable, all connected sequentially. The charging module is mounted on the vehicle mount and includes a human body sensor, a speaker, a display screen, and a wireless charging coil. The charging module's mainboard detects the presence of a person via the human body sensor and triggers the speaker to play a preset audio prompt, such as a reminder to use the vehicle charger or if a phone has been left behind. The human body sensor automatically detects the user's approach, triggering automatic wake-up or energy-saving sleep mode to reduce standby power consumption. The display screen can show promotional content as needed, eliminating the need for manually tearing and pasting promotional leaflets. The charging cable and wireless charging coil enable dual-mode charging to meet different passenger charging needs, significantly enhancing the functionality of the vehicle charger and thus greatly improving the user experience.
[0144] 2. By setting up an NFC reader / writer, a human body sensor, a light, and a QR code sign, the car charger can directly interact with a mobile phone equipped with an NFC tag via the NFC reader / writer, enabling one-touch connection. This eliminates the need to open the camera to scan and navigate. Alternatively, users can scan the QR code on the sign according to their personal preferences. When the charging motherboard detects the presence of a passenger via the human body sensor and the ambient light sensor detects that the ambient light brightness is below a preset brightness threshold, it automatically turns on the light to illuminate the QR code sign, improving the recognition success rate. Furthermore, the QR code sign is more resistant to mechanical wear and UV degradation than traditional QR code stickers, greatly improving the convenience, flexibility, efficiency, and durability of the car charger.
[0145] 3. By setting up a camera, it can serve as a supplementary camera for the vehicle to record driving logs, further enhancing the functionality of the onboard charger.
[0146] 4. By adding two additional USB-A ports on the power module, the charging needs of multiple devices can be met; by setting up dual USB-C + Lightning ports on the charging cable, the interface standards of mainstream devices can be covered, reducing the need for adapters and greatly improving the user experience.
[0147] 5. By setting a temperature sensor to monitor the temperature of the car charger, the charging power can be reduced or charging can be stopped when the temperature is too high, thus greatly improving the safety of the car charger.
[0148] 6. By integrating the communication module and the locator, remote status monitoring and location tracking functions can be achieved.
[0149] 7. By integrating a light into the camera, the pain point of inconvenient charging at night is solved. The light brightness can be intelligently adjusted according to the human body sensor signal, taking into account both practicality and atmosphere.
[0150] 8. By setting clips and threaded fasteners on the vehicle mount, the installation method of the vehicle mount can be flexibly selected. For example, the vehicle mount can be clamped to the headrest vertical bar of the first row of seats in the vehicle, or the elastic band can be threaded through the rear end of the threaded fastener and locked onto the headrest of the first row of seats for installation, which greatly improves the applicability. By setting a cable winding groove on the vehicle mount, it is easy to store the charging cable, which further enhances the functionality of the vehicle charger.
[0151] 9. By setting a winding groove in the middle of the support rod, the charging cable can be easily wound up and stored, avoiding random placement of the charging cable and greatly improving the user experience.
[0152] 10. The combination structure of the ball joint and the support rod supports 360° rotation, adapting to different installation environments and usage requirements.
[0153] 11. By setting the support plate as a metal support plate and setting a magnetic iron sheet on the outside of the charging housing of the charging module, the charging module can be magnetically attracted to the support plate by the magnetic iron sheet. Combined with the positioning groove set in the support plate, it can be quickly positioned, taking into account the convenience of picking up the charging module and the stability of its placement. In addition, the metal support plate can effectively improve the heat dissipation performance.
[0154] 12. By setting the support plate as a rounded rectangle, the safety of the vehicle mount is effectively improved.
[0155] 13. By setting the inner side of the limiting component to be arc-shaped, it can better fit the charging module, thereby providing safety protection for the charging module.
[0156] 14. By setting a handle on one side of the clamp and several anti-slip protrusions on the other side, the clamp can be opened and closed easily, which greatly improves the convenience of assembling and disassembling the vehicle mount.
[0157] 15. By incorporating spring wires, cable tangling can be avoided, effectively improving storage convenience. They are also tensile and bend-resistant, making them suitable for complex wiring scenarios inside vehicles.
[0158] 16. By setting up a silicone protective sleeve, the bending stress of the wire is effectively relieved, and the wire ends are protected from wear. It is especially suitable for high-vibration conditions in the vehicle environment, thereby greatly improving the durability of the vehicle charger.
[0159] 17. The separate design of the power supply module and the charging module allows for independent replacement or upgrade of components, reducing maintenance costs.
[0160] 18. By setting male buckles and slots on the display mounting parts, and having several female buckles in the inner ring of the display mounting slot, the display mounting parts can be flexibly disassembled and assembled through the male buckles, female buckles, and slots, thereby greatly improving the user experience.
[0161] 19. By setting charging cable mounting holes in the charging housing, a cable clip cover is attached to the charging housing through screw holes and embedded in the charging cable mounting holes. The first Type-C male connector of the charging cable is connected to the Type-C female connector inside the charging housing through the wire hole of the cable clip cover. That is, the cable clip cover limits and fixes the first Type-C male connector of the charging cable. When the charging cable is damaged and needs to be replaced, simply unscrew the screw in the screw hole to remove the cable clip cover, and the charging cable can be quickly replaced without having to mail it back to the manufacturer for repair as in the past, thus greatly improving the convenience of car charger repair.
