Description

Technical Field

[0001] This utility model relates to the field of vehicle accessories, specifically a vehicle converter. Background Technology

[0002] With the continuous development of intelligent modern automobiles and electronic devices, car owners' demand for in-vehicle power supplies is increasing, especially the demand for high-power devices. However, most in-vehicle power solutions on the market still have some significant shortcomings, particularly in terms of power supply stability, charging speed, and applicability. These problems are mainly reflected in the following aspects:

[0003] The issue of automatic power disconnection after the engine is turned off: Many gasoline-powered vehicles automatically disconnect power within a few minutes after the engine is turned off. This prevents owners from continuing to use in-vehicle electrical appliances or charging them after parking, especially during long periods of parking, as it leaves devices without a power supply. This problem significantly limits the flexibility and convenience for owners to use electronic devices in their vehicles.

[0004] Slow USB charging speeds: Many vehicle USB ports are designed primarily for data transfer and haven't adequately considered the fast charging needs of drivers. Most car USB ports only offer about 10W of charging power, far from meeting the fast charging demands of modern smartphones, tablets, and other devices. Today, many mobile phones and other electronic devices offer fast charging power ranging from 25W to 66W, while the traditional 10W charging power of car USB ports is severely lagging behind, resulting in longer charging times and negatively impacting the user experience.

[0005] In addition, during the charging process, car owners often face the problem of tangled and messy cables. After charging is completed, car owners often do not have a convenient way to store the cables, which may result in the cables being piled up on the seats, in the cabin or other places inside the car. This not only affects the convenience of use, but may also bring safety hazards. Utility Model Content

[0006] The purpose of this invention is to provide an in-vehicle converter that converts the vehicle's 12V DC power into a stable 220V AC power output through an inverter module, thus solving the problem of automatic power cut-off when many gasoline vehicles are parked and turned off.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an on-board converter, comprising an inverter module and a converter module, wherein:

[0008] The inverter module is used to connect to a 12V vehicle power supply and perform voltage conversion. The inverter module includes the inverter body and the cigarette lighter socket. The positive terminal of the inverter body's input side is connected to the 12V vehicle power supply or the fuse box, and the negative terminal of the inverter body's input side is connected to the negative terminal of the vehicle power supply or to the vehicle body ground. The output side of the inverter body is connected to the cigarette lighter socket via a wire. When the inverter body's input side is connected to a 12V vehicle power supply, it can achieve high power output. When the inverter body's input side is connected to the fuse box, it can achieve a stable 150W power output.

[0009] The converter module is used to connect to the inverter module and provides connector conversion functionality. The converter module includes:

[0010] The contact end is configured to connect with the cigarette lighter socket and conduct through the springs distributed at its bottom end and the gap between the contact ceramic seat and the socket of the cigarette lighter socket to ensure a firm electrical contact and stable conduction performance. A connection surface is provided at the upper end of the contact end.

[0011] The conversion end is located on the upper side of the contact end. The conversion end includes an upper end cover, a lower end cover, and a telescopic cover plate. The lower end cover is connected to the upper end of the contact end through a connecting plate. The four corners of the lower end cover are connected to the upper end cover through guide posts. The upper end cover is in the shape of a trapezoid with a larger lower end and a smaller upper end. The upper end cover is provided with a single-phase five-hole socket. A ring of light strip for power indication is provided in the middle of the upper end cover.

[0012] Preferably, the bottom of the upper cover has an adjustment hole corresponding to the guide post, and a telescopic cover surrounds the outside of the guide post with its upper and lower ends connected to the upper and lower covers, respectively. The telescopic cover adopts a bellows-like telescopic structure, allowing the upper cover to be adjusted in height according to different vehicle environments and adapting to the usage needs of different vehicles through the adjustment hole and the telescopic cover's movement relative to the lower cover. The bellows structure of the telescopic cover provides greater flexibility while ensuring stability, allowing vehicle owners to adjust it according to actual conditions to meet the needs of different interior spaces and layouts.

[0013] Preferably, multiple parallel adjustment grooves are provided on the upper end of the contact end and on the left and right sides of the upper end cover, and a multi-functional plug-in that cooperates with the adjustment grooves is provided on the outer side of the conversion end.

[0014] Preferably, the multi-functional plug-in includes a plug-in bracket that slides into the adjustment slot, cable securing clips distributed on the end face of the plug-in bracket, a cable storage slot, and a winding slot. The multi-functional plug-in provides convenient cable management, making cable storage and organization easier. The cable securing clips, through the combination of a rotating disc and a U-shaped cable management clip, effectively secure cables and prevent tangling or damage. The plug-in bracket features a cable storage slot, a winding slot, and multiple winding protrusions, allowing car owners to easily organize cables of different lengths (such as USB-A charging cables, CC / CL charging cables, etc.), avoiding inconvenience or safety hazards caused by messy cables. This design allows car owners to manage vehicle cables more neatly, improving the user experience.

[0015] Preferably, the cable fixing buckle includes a rotating disk and a U-shaped cable management buckle integrally formed on the end face of the rotating disk, wherein the rotating disk is movably mounted on the upper end of the plug-in bracket.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model converts the vehicle's 12V DC power into a stable 220V AC power output using an inverter module, solving the problem of automatic power cut-off in many gasoline vehicles after the engine is turned off. Traditional vehicle power systems often stop supplying power immediately after the engine is turned off, while this utility model can continuously provide high-power output to meet the needs of electrical appliances after long periods of parking, especially for devices requiring high-power power, such as car refrigerators, car TVs, projectors, and other electronic devices. In addition, the multi-functional plug-in design provides cable management functions such as cable securing clips, cable storage slots, and winding slots. These designs effectively prevent cable tangling, helping car owners to organize various cables more neatly and safely, avoiding inconvenience or safety hazards caused by messy cables.

[0019] 2. The telescopic cover of this utility model adopts a corrugated pipe structure, which allows the height of the upper cover to be adjusted according to the space of different vehicles, providing greater flexibility.
