[0002] With the widespread use of electronic devices, people are using mobile phones, tablets, and other devices in their cars more and more frequently, making car chargers an indispensable accessory. To meet the need to charge multiple devices simultaneously, many car chargers with multiple USB ports have appeared on the market. However, existing car chargers of this type have some obvious drawbacks. Multiple ports are exposed, making them difficult to protect. Vibrations generated during vehicle operation may cause debris to enter the ports more easily, leading to short circuits and other malfunctions, affecting the normal use of the charger, and even potentially damaging the connected electronic devices. In addition, when some ports are not in use, they cannot be individually protected, further increasing the risk of damage to the ports. Utility Model Content

[0021] 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.

[0022] Example 1

[0023] Please see Figures 1-3 This is the first embodiment of the present invention, which provides a multi-port USB splitting structure for a car charger, including...

[0024] The connector 1 has a charging head 2 on its top. The connector 1 provides support for the charging head 2, and the charging head 2 has multiple connection ports 21. The connection ports 21 in this application are USB connection ports. The charging head 2 has a shunt circuit inside, which is electrically connected to the multiple USB connection ports 21. When the connector 1 is inserted into the vehicle power interface, the power is distributed to each USB connection port 21 through the shunt circuit to charge the connected electronic devices.

[0025] The protective components include a protective cover 3 detachably mounted on the top of the charging head 2, which covers the top of the charging head 2; multiple ports 32 corresponding to the connection ports 21 are opened on the top of the protective cover 3, enabling the opening of the ports 32; support plates 4 are symmetrically installed on the inner side of any port 32, enabling the addition of support plates 4; and protective plates 5 are detachably mounted on the top of the two support plates 4, which increase the support of the support plates 4 for the protective plates 5. By setting up the protective components, the protective cover 3 can protect multiple USB connection ports 21 as a whole, reducing the possibility of foreign objects entering. When a certain USB connection port 21 needs to be used, the corresponding protective plate 5 can be removed to expose the corresponding USB connection port 21. When not in use, the protective plate 5 can be used to cover it, realizing the individual protection of any connection port 21.

[0026] In this embodiment, preferably, a fastening plate 6 is symmetrically arranged on the inner side of any one of the insertion ports 32, thereby realizing the addition of the fastening plate 6. A rubber pad 61 is arranged on the side surface of the fastening plate 6 and can press against the side surface of the protective plate 5. When the protective plate 5 is inserted, the cooperation of the fastening plate 6 and the rubber pad 61 is used for reinforcement.

[0027] In this embodiment, preferably, a pull handle 51 is installed on the top of any of the protective plates 5 to increase the convenience of pulling up and down the protective plate 5. A connecting rope 52 is provided on the front surface of any of the protective plates 5 and is fixedly connected to the protective cover 3. By splicing the connecting rope 52 and the protective cover 3, the performance of the protective plate 5 after it is removed is increased.

[0028] Example 2

[0029] Please see Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that:

[0030] It also includes a first protruding ear 31 symmetrically arranged on the outer wall of the protective cover 3, realizing the addition of the first protruding ear 31, and a second protruding ear 22 symmetrically arranged on the outer wall of the charging head 2, realizing the addition of the second protruding ear 22; the second protruding ear 22 has a fixing hole 220 inside, realizing the opening of the fixing hole 220, and the bottom of the first protruding ear 31 has a fixing block 310 that passes through the fixing hole 220. When the protective cover 3 and the charging head 2 are spliced, the fixing block 310 passes through the fixing hole 220; it also includes a through hole 3101 opened inside the fixing block 310, realizing the opening of the through hole 3101. A vertical plate 221 is provided at the bottom of the second protruding ear 22, which realizes the addition of the vertical plate 221. A through hole is opened inside the vertical plate 221, which realizes the opening of the through hole. A horizontal rod 7 passes through the through hole and through hole 3101. A threaded part 71 is provided on the horizontal rod 7, which realizes the addition of the threaded part 71. A nut 8 is provided on the fixing block 310, which is threadedly connected to the threaded part 71. When in use, the horizontal rod 7 passes through the through hole and through hole 3101. The nut 8 is picked up, and the engagement of the nut 8 and the threaded part 71 increases the stability of the fixing block 310, thereby realizing the stable installation of the protective cover 3.

[0031] The working principle and usage process of this utility model: Align the protective cover 3 with the top of the charging head 2, so that the first protruding ear 31 on the outer wall of the protective cover 3 corresponds to the second protruding ear 22 on the outer wall of the charging head 2; at this time, the fixing block 310 at the bottom of the first protruding ear 31 passes through the fixing hole 220 inside the second protruding ear 22.

[0032] The horizontal bar 7 passes through the through hole inside the vertical plate 221 and the through hole 3101 inside the fixing block 310;

[0033] Pick up nut 8 and screw it into the threaded part 71 on the horizontal bar 7. Tighten nut 8 to make the protective cover 3 securely installed on the charging head 2.

[0034] Insert the connector 1 into the vehicle power interface. At this time, the power is distributed to each USB port 21 through the shunt circuit in the charging head 2.

[0035] When you need to charge an electronic device, locate the corresponding USB port 21, pull off the protective plate 5 corresponding to the port 21 using the pull handle 51, and insert the charging cable of the electronic device into the exposed USB port 21 to charge the device.

[0036] When a USB port 21 is not in use, the protective plate 5 is placed back into the corresponding port 32. During the insertion of the protective plate 5, the rubber pad 61 on the side surface of the fastening plate 6 will press against the side surface of the protective plate 5 to reinforce the protective plate 5, thereby using the protective plate 5 to cover the USB port 21 and achieve protection.

[0037] Although embodiments of the present invention have been shown and described in detail above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
