Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of vehicle charging equipment, and in particular to a human body induction 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 cannot sense whether there are passengers in the vehicle. Even when there are no passengers and the charger is in an unloaded state, the charger still maintains full power operation, resulting in excessive static power consumption (typical value > 0.5W), which wastes the vehicle's power resources. Moreover, when traveling at night in poor lighting conditions, passengers may not be able to notice the car charger in time, reducing the frequency of use of the car charger and causing passengers to miss the opportunity to replenish their mobile devices in time, which seriously affects the user experience.
[0005] Therefore, how to provide a human body induction-type vehicle charger that reduces power consumption and improves user experience has become an urgent technical problem to be solved. Summary of the Invention

[0033] A nut, rotatably connected to the ball head, is used to lock the clamp.
[0034] Furthermore, the support plate is a metal support plate.
[0035] Furthermore, the first charging port is a USB-C port; the second charging port is a Lightning port.
