Description

Technical Field

[0001] This utility model relates to the field of vehicle charging equipment technology, and in particular to a vehicle charger equipped with a pluggable charging cable. Background Technology

[0002] In ride-hailing operations, approximately 67% of passengers have temporary charging needs, but due to differences in vehicle configuration standards, there is generally a supply shortage of rear-seat power outlets. With the exponential growth in demand for mobile device charging, the on-board charger, as a core component of on-board power conversion devices, is receiving increasing attention for its application efficiency in public transportation services.

[0003] In the current technology system, vehicle chargers generally obtain 12V / 24V DC power through the cigarette lighter receptacle, output 5V DC power to adapt to mobile terminals through the built-in voltage conversion module, and adopt a fixed charging harness layout, which is commonly found in the device mounting position behind the front seat headrest.

[0004] Over time, the charging cable of a car charger, due to stretching and bending, will experience stress concentration, accelerating the fatigue fracture of the TPE insulation layer and exposing the internal wires. Exposed wires not only accelerate the damage process but also pose a safety hazard, necessitating cable replacement. However, because traditional car charger cables have a one-piece structure (non-detachable), direct cable replacement is not possible, meaning on-site repair is not feasible. The car charger must be mailed back to the manufacturer for repair, which is very inconvenient.

[0005] Therefore, how to provide a vehicle charger with a pluggable charging cable to improve the convenience of vehicle charger maintenance has become an urgent technical problem to be solved. Summary of the Invention
