[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] Example 1:

[0048] like Figures 1 to 6 As shown, this utility model provides a multifunctional vehicle power converter, including: a power converter 1 and a socket 2 disposed on the power converter 1.

[0049] To prevent water from splashing into the socket 2 during placement of the power converter 1 and causing damage to the device, a protective structure is arranged on one side of the power converter 1 to prevent water from splashing into the socket 2, with the socket 2 located inside the protective structure.

[0050] The protective structure includes a protective cover 3 arranged on one side of the power converter 1, a baffle 301 rotatably installed inside the protective cover 3, a fixed shaft 302 arranged on the inner wall of the protective cover 3 as the fulcrum for the rotation of the baffle 301, the baffle 301 being rotatably sleeved on the fixed shaft 302, and a limiting component arranged on the inner wall of the baffle 301. The baffle 301 can block the protective cover 3 to prevent dust or water from splashing into the socket 2. At the same time, the baffle 301 can rotate on the fixed shaft 302 to open the protective cover 3.

[0051] Specifically, the limiting component includes a torsion spring 303 sleeved on the fixed shaft 302 for driving the baffle 301 to flip and reset. One end of the torsion spring 303 is arranged on the inner wall of the baffle 301, and the other end of the torsion spring 303 is arranged on the fixed shaft 302. When the torsion spring 303 is in a contracted state, the torsion force of the torsion spring 303 can keep the baffle 301 in a closed state. When the baffle 301 is squeezed by the plug, it can rotate on the fixed shaft 302, and at the same time further compress the torsion spring 303.

[0052] Example 2:

[0053] Based on Embodiment 1, in order to prevent the plug from coming off due to vehicle vibration or the drop of the power converter 1 after the plug is connected to the socket 2, an anti-loosening structure for pressing the connecting wire is arranged on the protective structure, and a triggering structure for triggering the anti-loosening structure to perform a squeezing operation is arranged on the anti-loosening structure.

[0054] The anti-loosening structure includes a clamping plate 4 for pressing the connecting wire, a mounting slide rod 401 movably mounted on the clamping plate 4, a guide rod 402 slidably mounted inside the mounting slide rod 401 to guide the movement of the mounting slide rod 401, a fixing seat 403 and a connecting seat 404 arranged on one side of the protective cover 3 to support the guide rod 402, the fixing seat 403 and the connecting seat 404 being respectively arranged at both ends of the guide rod 402, and a spring 405 slidably sleeved on the guide rod 402, the spring 405 being arranged between the connecting seat 404 and the mounting slide rod 401, the spring 405 being able to pull the mounting slide rod 401 to move, the mounting slide rod 401 sliding on the guide rod 402 when it moves, thereby restricting the direction of movement of the mounting slide rod 401, so that the mounting slide rod 401 drives the clamping plate 4 to clamp the connecting wire of the plug, thereby reinforcing the connection of the connecting wire.

[0055] The anti-loosening structure also includes an installation component, which is arranged on the clamping plate 4 and used to fix or remove the clamping plate 4. The installation component includes a positioning hole 406 opened inside the mounting slide rod 401, and a mounting bolt 407 threaded inside the clamping plate 4 and the mounting slide rod 401. The clamping plate 4 is movably installed in the positioning hole 406. By rotating the mounting bolt 407, it can be unscrewed from the clamping plate 4 and the mounting slide rod 401, which can release the connection restriction on the clamping plate 4. At this time, the clamping plate 4 can be pulled out from the positioning hole 406, and clamping plates 4 with different clamping groove sizes can be replaced.

[0056] The triggering structure includes an arc-shaped stop bar 5 arranged on one side of the baffle 301, an arc groove 501 opened inside the protective cover 3, the arc-shaped stop bar 5 being movably installed in the arc groove 501, and a limiting post 502 arranged on the mounting slide bar 401. The limiting post 502 is in contact with one side of the arc-shaped stop bar 5. When the baffle 301 flips, it can drive the arc-shaped stop bar 5 to move in the arc groove 501 and disengage from the limiting post 502. At this time, the spring 405, which is in a stretched state, will contract and pull the mounting slide bar 401 to move.

[0057] Working principle:

[0058] In use, the plug is held and pressed against the two baffles 301. When the baffles 301 are pressed, they can rotate on the fixed shaft 302, further compressing the torsion spring 303. The flipped baffles 301 expose the socket 2, allowing the plug to be inserted into it. Simultaneously, the plug moves its connecting wire between the two clamps 4. As the baffles 301 flip, the arc-shaped stop bar 5 moves within the arc groove 501. The continuously moving arc-shaped stop bar 5 disengages from the limiting post 502. Since the spring 405 is in a stretched, energy-stored state, when the limiting post 502 is no longer blocked by the arc-shaped stop bar 5, the stretched spring 405 contracts and pulls the mounting slide bar 401. The mounting slide bar 401 slides on the guide rod 402, thus restricting its direction of movement. This causes the mounting slide bar 401 to clamp the clamps 4 onto the plug's connecting wire, thus connecting the wire. To prevent loosening, the clamping plate 4 is tightened and unscrewed from the mounting bolt 407, thus releasing the connection restriction on the clamping plate 4. The clamping plate 4 can then be pulled out of the positioning hole 406. Clamping plates 4 with different groove sizes can be replaced to clamp different sized connecting wires. When the connecting wire needs to be unplugged, the mounting rod 401 is pulled to move the clamping plate 4 back to its original position, releasing it from the pressure on the connecting wire. The connecting wire can then be pulled to unplug the plug. Simultaneously, the baffle 301 is no longer compressed by the plug. The compressed torsion spring 303 causes the baffle 301 to flip back to its original position, sealing the protective cover 3 and preventing dust or water from splashing into the socket 2. The reset baffle 301 also causes the arc-shaped stop bar 5 to move back to its original position, making it re-contact the surface of the limiting post 502, blocking the limiting post 502 and preventing the mounting rod 401 from loosening, thus facilitating subsequent use.

[0059] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
