Description

Technical Field

[0001] This utility model relates to the field of vehicle charging equipment technology, and in particular to a vehicle charger with a display screen. 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 only have the function of charging, which is limited. For example, they cannot sense whether there are passengers in the back seat or notify rear passengers that they can use the car charger to charge. In addition, car chargers need to display promotional content and need to be changed periodically. The traditional method is to stick a display leaflet on the body of the car charger. When the display content needs to be changed, the display leaflet has to be torn off and re-stitched. This not only easily leaves glue residue on the body, but the display leaflet is also easy to tear or lose its stickiness, which is not conducive to reuse. As a result, the overall user experience of the car charger is not good.

[0005] Therefore, how to provide a car charger with a built-in display screen to improve the functionality of the car charger has become a technical problem that urgently needs to be solved. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a vehicle charger with a display screen, thereby improving the functionality of the vehicle charger.

[0032] A negative electrode spring is provided on the outer side of the lower part of the power collection housing and is connected to the negative input terminal of the DC-DC module;

[0033] A positive contact is located at the bottom of the power-collecting housing and is connected to the positive input terminal of the DC-DC module;

[0034] Two USB-A ports are located side-by-side on the top of the power-generating housing and are connected to the output of the DC-DC module.

[0035] Furthermore, the vehicle mount includes:

[0036] A support plate has four symmetrically arranged limiting parts on the front that match the charging module, and a ball head seat on the back.
