Description

Technical Field

[0001] This utility model relates to the field of socket technology, and in particular to a vehicle-mounted USB socket. Background Technology

[0002] A USB socket is a universal power supply device with an integrated USB interface, outputting 5V and belonging to low-voltage electronic products. With the widespread use of electronic devices and the development of intelligent automobiles, there is a need for cars to power electronic devices brought into the vehicle. Using a USB socket to power electronic devices is a good choice. With the decrease in the number of smokers and the increase in awareness of not smoking in cars, cigarette lighters are rarely used anymore, leading to the emergence of in-car USB sockets that connect to the car's cigarette lighter interface.

[0003] Existing in-vehicle USB sockets typically use dust covers to shield the USB ports, preventing dust accumulation when the ports are not in use for extended periods. However, this design has several drawbacks: the dust cover needs to be aligned with the socket and snapped on to cover the port. If the driver tries to snap the dust cover on while driving, it will distract the driver and affect driving safety. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a vehicle USB socket. This invention uses a magnetic connection to fasten the dust cover to the socket body, so that the driver can easily fasten the dust cover while driving without being distracted or affecting driving safety.

[0005] The technical solution adopted by this utility model is as follows: A vehicle USB socket includes a socket body and a dust cover. One end of the socket body is provided with a terminal for electrical connection with a car, and the other end is provided with a USB interface for power supply. The socket body is also provided with a panel at the end corresponding to the USB interface. The dust cover covers the USB interface by fastening it with the panel. The end face of the panel is provided with a groove for one end of the dust cover to be inserted. The inner peripheral wall of the groove is provided with a first inclined surface. The outer peripheral wall of the dust cover is provided with a second inclined surface adapted to the first inclined surface. A first annular magnet is embedded on the first inclined surface, and a second annular magnet that is magnetically attracted to the first annular magnet is embedded on the second inclined surface.

[0006] The dust cover has a recessed circular groove on the end face away from the second inclined surface, and the inner bottom surface of the circular groove is provided with raised texture.

[0007] A rocker arm extends radially from the outer peripheral wall of the dust cover, with the end of the rocker arm extending to the outside of the panel.

[0008] The inner bottom surface of the groove is provided with an elastic sealing ring, which is arranged around the outer periphery of the USB interface. The dust cover is also provided with a sealing block for inserting into the USB interface.

[0009] The dust cover is also connected to a mounting ring via a folding tab. The mounting ring is sleeved on the socket body. When the dust cover is fastened to the panel, the mounting ring and the dust cover are located on opposite sides of the panel.

[0010] The panel is snapped onto one end of the socket body corresponding to the USB interface, and the inner wall of the panel has at least one protruding locking block, while the socket body has at least one recessed locking groove that matches the locking block.

[0011] The edge of the USB interface is folded outward to form a bent portion. The panel is provided with at least two corner blocks. The two corner blocks are symmetrically arranged with respect to the center of the USB interface, and a mounting portion for the bent portion to be inserted is formed between the two corner blocks.

[0012] The panel is welded to the socket body or glued together.

[0013] The beneficial effects of this utility model are as follows: This utility model uses a magnetic connection method to fasten the dust cover to the socket body. Specifically, a first annular magnet and a second annular magnet are respectively set on the first and second inclined surfaces to attract each other. When the dust cover approaches the groove of the panel, it can be automatically attracted and aligned under the action of magnetic force, eliminating the need for the driver to accurately align or try multiple times. It can also achieve blind-mounting. The driver can easily operate and fasten the dust cover while driving without being distracted or affecting driving safety. Both annular magnets are embedded on the inclined surfaces. Even if the dust cover is closed crookedly, it can still be attracted by the magnetic force to slide into the groove, simplifying the operation steps of fastening the dust cover and improving the user experience. In addition, the magnetic structure can also improve the sealing between the dust cover and the panel, extending the service life of the USB socket. The dust cover cannot be easily opened when it is fastened, improving the overall aesthetics. Attached Figure Description

Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0019] like Figures 1 to 7As shown in the figure, an embodiment of the present invention is provided, which is a vehicle-mounted USB socket, including a socket body 1 and a dust cover 2. One end of the socket body 1 is provided with a terminal 3 for electrical connection with the vehicle, and the other end is provided with a USB interface 4 for power supply. The socket body 1 is also provided with a panel 5 at the end corresponding to the USB interface 4. The dust cover 2 covers the USB interface 4 by fastening it with the panel 5. The end face of the panel 5 is provided with a groove 6 for one end of the dust cover 2 to be inserted. The inner peripheral wall of the groove 6 is provided with a first inclined surface 7. The outer peripheral wall of the dust cover 2 is provided with a second inclined surface 8 that matches the first inclined surface 7. A first annular magnet 9 is embedded in the first inclined surface 7, and a second annular magnet 10 that is magnetically attracted to the first annular magnet 9 is embedded in the second inclined surface 8.

[0020] The beneficial effects of this design are as follows: This utility model uses a magnetic connection to fasten the dust cover to the socket body. Specifically, a first annular magnet and a second annular magnet are respectively set on the first and second inclined surfaces to attract each other. When the dust cover approaches the panel groove, it can automatically be attracted and aligned under the action of magnetic force, eliminating the need for the driver to precisely align or attempt multiple times. It can also achieve blind-mounting, allowing the driver to easily fasten the dust cover while driving without distraction or affecting driving safety. Both annular magnets are embedded on the inclined surfaces, so even if the dust cover is placed crookedly, it can still be attracted by the magnetic force to slide into the groove, simplifying the operation of fastening the dust cover, improving the user experience, and the magnetic structure can also improve the sealing between the dust cover and the panel, extending the service life of the USB socket. The dust cover will not be easily opened when it is fastened, improving the overall aesthetics.

[0021] As a further feature, the end face of the dust cover 2 away from the second inclined surface 8 is recessed with a circular groove 11, and the inner bottom surface of the circular groove 11 is provided with raised texture 12.

[0022] The beneficial effects of this design are as follows: the combination of the round groove and the raised texture significantly increases the friction between the fingers and the dust cover, making it easier and more reliable to fasten the dust cover, and also making it easier to operate with one hand. The raised texture design enhances the surface roughness, provides clear tactile feedback, and facilitates blind operation.

[0023] As a further feature, a rocker arm 13 extends radially from the outer peripheral wall of the dust cover 2, and the end of the rocker arm 13 extends to the outside of the panel 5.

[0024] The benefits of this design are as follows: the rocker extends to the outside of the panel, providing a natural point of force application, eliminating the need to pry open the dust cover through gaps, making it easy to open quickly and effortlessly. Furthermore, the lever principle amplifies the operating force, making it easy to lift even when the magnetic attraction is strong, and it also allows for blind opening, further reducing distractions.

[0025] Furthermore, the inner bottom surface of the groove 6 is provided with an elastic sealing ring 14, which is arranged around the outer periphery of the USB interface 4. The dust cover 2 is also provided with a sealing block 15 that is inserted into the USB interface 4.

[0026] The beneficial effects of this design are as follows: the elastic sealing ring further enhances the sealing between the dust cover and the panel; placing the elastic sealing ring in the groove does not affect the magnetic attraction of the ring magnet on the inclined surface, ensuring the fit and firmness of the magnetic attraction; and inserting the sealing block into the USB interface uses physical isolation to protect the metal contacts of the USB interface, reducing oxidation and contamination, and extending the service life of the socket.

[0027] Furthermore, the dust cover 2 is connected to an installation ring 17 via a folding tab 16. The installation ring 17 is fitted onto the socket body 1. When the dust cover 2 is fastened to the panel 5, the installation ring 17 and the dust cover 2 are located on opposite sides of the panel 5.

[0028] The benefits of this design are as follows: the dust cover remains connected to the socket body via the folding tab and the mounting ring, effectively preventing the dust cover from being lost, simplifying the operation process of using the USB socket, and allowing charging without completely removing the dust cover, thus improving the convenience of operation.

[0029] In a further configuration, the panel 5 is snapped onto one end of the socket body 1 corresponding to the USB interface 4, and the inner wall of the panel 5 has at least one protruding locking block 18, and the socket body 1 has at least one recessed slot 19 that matches the locking block 18.

[0030] The advantages of this design are as follows: the panel and the socket body also adopt a detachable connection structure. The locking blocks on the panel and the locking slots on the socket body engage with each other to ensure that the panel and the socket body will not rotate or shift relative to each other, preventing the panel from becoming loose due to vibration. It also ensures the precise alignment of the USB interface and the dust cover, and facilitates the replacement or repair of parts in the future, reducing maintenance costs.

[0031] Further, the edge of the USB interface 4 is folded outward to form a bent portion 20, and the panel 5 is provided with at least two corner blocks 21. The two corner blocks 21 are symmetrically arranged with respect to the center of the USB interface 4, and a mounting portion 22 for the bent portion 20 to be embedded is formed between the two corner blocks 21.

[0032] The beneficial effects of this design are as follows: the mounting section formed by the bent part and the symmetrically arranged corner blocks achieves multi-point rigid fixation between the USB interface and the panel, effectively resisting continuous vibration in the vehicle environment and preventing the interface from loosening or shifting. The symmetrical corner block structure provides clear installation guidance, simplifies the positioning and fixing process of the USB interface, reduces assembly errors, and is suitable for automated mass production.

[0033] Further, the panel 5 is welded or glued to the socket body 1.

[0034] The benefits of this setup are as follows: it allows for flexible selection of different installation techniques, and whether welding or adhesive bonding is used, high-strength fixation can be achieved without the need for additional installation accessories, optimizing the assembly process, improving production efficiency while ensuring connection reliability.

[0035] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
