Description

Technical Field

[0001] The utility model relates to the technical field of vehicle chargers, in particular to a vehicle USB socket with multiple sockets. Background Art

[0002] The car charger is an accessory designed to facilitate users to charge digital products with the car's power supply. The general car charger interface is two USB ports or one USB port plus a Type-C port. It is directly plugged into the car's cigarette lighter slot to meet charging needs.

[0003] In the related technology, a solution of a multi-interface car charger (Announcement No. CN212033813U) was found through search. The charger base cooperates with the positive metal ball through the connecting column, and is directly plugged into the vehicle cigarette lighter slot. The positive metal ball is connected to the power supply for easy power supply. The rotating charging seat is connected to the power supply when the plug column and the slot are plugged in. The positive metal column is plugged into the circular groove to connect the power supply to the USB connection hole. The limit paddle is correspondingly engaged with the ring groove to prevent the rotating charging seat from detaching.

[0004] However, the structure of the on-board charger of the above scheme is similar to most of the on-board chargers commonly used in the industry. Although it provides multiple USB interfaces and can power multiple devices at the same time, when it is used in a truck, since the cigarette lighter interface of the truck is mostly located on the center console, and the center console is a certain distance away from the back row, if the passengers sitting in the back row of the truck want to use the on-board charger for power supply, when the charging cable is not long enough, the charging cable may be accidentally dragged and the on-board charger may be pulled out of the cigarette lighter or the charging cable may be separated from the on-board charger, making charging inconvenient. Utility Model Content

[0014] Furthermore, a rubber ring is sleeved on the surface of the plug-in tube, and the rubber ring abuts against the inside of the USB power supply head. The rubber ring increases the friction between the USB power supply head and the plug-in tube to prevent the USB power supply head from loosening from the plug.

[0015] Furthermore, a protective pad is provided on the inner surface of the chuck, and after the chuck is connected to the air outlet of the air conditioner, the protective pad protects the air outlet of the air conditioner.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The USB power supply head and the plug can be separated by the plug-in and unplugging structure, and the USB power supply head can be powered by the spiral telescopic cable, thereby expanding the moving range of the USB power supply head. When the device is charged with the charging cable, it can be conveniently charged in the front or rear seat of the truck, and the problem of the charging cable pulling the vehicle charger is not likely to occur.

[0018] (2) The USB power supply head can be attached to the interior cover of the truck through the suction cup, and the USB power supply head can be fixed to prevent the USB power supply head from moving freely due to the movement of the car. The suction cup is attached to the fixing plate and connected to the air outlet of the air conditioner using a clamp, which can also fix the USB power supply head and make it more convenient to use.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figure 1-4 The utility model provides a technical solution: a multi-socket vehicle USB socket, comprising a plug 1, a plug tube 13 is provided at the upper end of the plug 1, and a spiral retractable wire 12 electrically connected to the plug 1 is provided inside the plug tube 13;

[0027] A USB power supply head 3, wherein the USB power supply head 3 is electrically connected to the spiral telescopic wire 12, and the plug-in tube 13 is inserted into the USB power supply head 3;

[0028] The plug 1 matches with the cigarette lighter interface on the car, and the cigarette lighter interface is used to power the plug 1. The spiral telescopic wire 12 has a telescopic characteristic, and the USB power supply head 3 can also be powered by the spiral telescopic wire 12 after being separated from the plug 1.

[0029] The space inside the USB power supply head 3 and the plug 1 can store the spiral telescopic cable 12;

[0030] An elastic ring 5 is sleeved on the surface of the USB power supply head 3. The elastic ring 5 is fixedly connected to a threaded rod 6. A suction cup 11 is provided at the end of the threaded rod 6. A fixing plate 9 is connected to the surface of the suction cup 11. A clamp 10 is provided on the surface of the fixing plate 9. Both the suction cup 11 and the clamp 10 can supply power to the USB power supply head 3 to prevent the USB power supply head 3 from moving freely.

[0031] Specifically, Figure 1As shown, a screwing seat 7 is screwed on the surface of the threaded rod 6, and the screwing seat 7 is fixedly connected to a push plate 8, and the push plate 8 is located on the left side of the suction cup 11. When the screwing seat 7 is rotated, the push plate 8 is driven to move, and the push plate 8 squeezes the suction cup 11, so that the suction cup 11 is more firmly adsorbed inside the cab.

[0032] In this embodiment, if Figure 1 As shown, a concave ring 4 is provided on the surface of the plug 1, and the elastic ring 5 is placed inside the concave ring 4. The elastic ring 5 is elastic and is tightened inside the concave ring 4 to prevent the elastic ring 5 from moving on the surface of the plug 1.

[0033] In this embodiment, if Figure 2 As shown, a fixing ring 2 is provided on the surface of the plug 1, and a plurality of magnet blocks 15 are embedded inside the fixing ring 2. An iron ring 16 is fixedly connected to the lower end surface of the USB power supply head 3, and the position of the iron ring 16 corresponds to the magnet block 15. When the magnet block 15 attracts the iron ring 16, the USB power supply head 3 and the plug 1 can be magnetically fixed.

[0034] In this embodiment, if Figure 2 As shown, the surface of the plug tube 13 is sleeved with a rubber ring 14, and the rubber ring 14 is against the inside of the USB power supply head 3. The shell of the rubber ring 14 fills the gap between the plug tube 13 and the USB power supply head 3 to prevent the plug 1 from being separated freely from the USB power supply head 3.

[0035] In this embodiment, if Figure 2 As shown, a protective pad 17 is provided on the inner surface of the clamp 10. The clamp 10 is clamped on the air outlet of the air conditioner, and the protective pad 17 prevents the clamp 10 from damaging the air outlet of the air conditioner.

[0036] Specifically, when in use, unplug the plug 1 and the USB power supply head 3 to separate the plug 1 from the USB power supply head 3, and then insert the plug 1 into the cigarette lighter interface. The retractable characteristics of the spiral telescopic wire 12 can be used to separate the USB power supply head 3 from the plug 1, and the USB power supply head 3 can be fixed to a place where the suction cup 11 can be sucked by the suction cup 11 to prevent the spiral telescopic wire 12 from pulling the USB power supply head 3. After the twisting seat 7 is twisted, the push plate 8 drives the suction cup 11 to ensure the stability of the suction cup 11. The suction cup 11 can also be fixed to the fixing plate 9, and the clamp 10 can be clamped to the air outlet of the air conditioner or other places that can be clamped, so as to facilitate the fixation of the USB power supply head 3. The spiral telescopic wire 12 can make up for the defect of insufficient charging length, making it more convenient to power the device.
