Description

Technical Field

[0001] This utility model relates to the field of charger plugs, specifically a plug flipping mechanism. Background Technology

[0002] Conventional chargers, especially those conforming to European standards, typically have a fixed AC plug design due to size and safety regulations. This results in a bulky charger that is inconvenient to carry.

[0003] There are two main types of existing charger plug designs: 1. For smaller sizes like the Chinese and American sizes, the plug rotates via a hinge at the bottom. Rotate the plug to use it, and rotate it to store it when not in use. 2. European safety regulations require large dimensions, and these are generally fixed to the outer shell and cannot be folded for storage.

[0004] The second type of plug is inconvenient to store due to its larger size. Therefore, there is an urgent need to provide a plug flipping mechanism to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this invention is to provide a pin flipping mechanism to solve the problems mentioned in the background art.

[0006] This utility model is implemented as follows: a pin flipping mechanism, comprising: Upper cover unit, lower cover unit, and pin module disposed on the lower cover unit; The lower cover unit includes a lower cover disposed on the upper cover unit, and the lower cover is provided with contact teeth; The pin module includes a housing, pins, rotating teeth, and springs. The pins are installed inside the housing, the rotating teeth are slidably disposed on both sides of the housing and mesh with the contact teeth, and the springs are disposed inside the housing to provide elastic support for the rotating teeth.

[0007] As a further embodiment of this utility model: the housing includes a front housing and a rear housing of the plugs that are spliced ​​together.

[0008] As a further embodiment of this utility model, the front shell and the rear shell of the pin are fixed together by screws.

[0009] As a further embodiment of this utility model: the upper cover unit includes an upper cover connected to the lower cover.

[0010] As a further embodiment of this utility model: a PCBA is provided inside the upper cover.

[0011] As a further embodiment of this utility model: the pin is provided with a first power line connected to the spring, and the spring and the rotating teeth are connected to the contact teeth.

[0012] As a further embodiment of this invention: the contact teeth are connected to the PCBA via a second power line.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The spring is located behind the rotating tooth. The rotating tooth can extend and retract through the spring. The pin module rotates around the central axis formed by the rotating tooth and the contact tooth. When it rotates to the highest point of a certain tooth, the meshing surface of the rotating tooth is subjected to force, which drives the rotating tooth to move into the pin module. When it rotates to the lowest point of the tooth, the rotating tooth receives the force from the rear spring and moves outward from the pin module, realizing the flipping function for easy storage.
