Description

Technical Field

[0001] The utility model relates to the technical field of cigarette lighters, and in particular to a multifunctional expansion car charger. Background Art

[0002] With the development of automobiles and the continuous changes in people's needs, the cigarette lighter interface can usually be equipped with a car inverter to charge mobile electronic devices, etc. The elastic head in the middle of the interface is the positive pole, and the buckles on both sides are the negative pole. The power supply is directly connected to the car battery, and the current power is the same as the battery.

[0003] Chinese patent CN216331651U discloses a car cigarette lighter fixing bracket. When in use, the push plate is pushed, and the push plate drives the extrusion column to move. The extrusion column squeezes the inclined surface of the guide plate to make the two guide plates approach each other, so that the guide plate drives the connecting line to move, the connecting line pulls the pressure plate to move, and the pressure plate drives the sponge pad to move. At the same time, the pressure plate squeezes the connecting spring 1 to make the two pressure plates move away from each other, and then the object fixed to the cigarette lighter is moved, and the object drives the connecting part with the cigarette lighter to pass through the annular plate into the inside of the cigarette lighter, and then the push plate is released. Under the elastic force of the connecting spring 3, the push plate returns to the initial position, and under the elastic force of the connecting spring 2, the guide plates move away from each other. Under the elastic force of the connecting spring, the pressure plate drives the sponge pad to press and fix the outer wall of the object inside the annular plate, thereby completing the fixation.

[0004] The applicant discovered the following technical problems when implementing the above technical solution:

[0005] The arrangement of the connecting spring of the device will be deviated by the object to be inserted during use, causing the pressure plate to deviate from the position, which in turn leads to the problem that the inserted object is not firmly fixed; and the traditional cigarette lighter port only relies on a conductive sheet to clamp the cigarette lighter plug. This clamping method is relatively loose and is prone to power outages when using some electrical appliances.

[0006] Therefore, it is an urgent problem to be solved by the present invention to provide a multifunctional expanded car charger with an expanded cigarette lighter port, whose reset elastic parts of the fixed components are reasonably arranged and will not be deviated by the inserted objects, thereby preventing the cigarette lighter plug from loosening and causing power outages.
