[0030] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0031] In one embodiment of the present invention, referring to Figures 1 to 6 , a detachable vehicle charger is provided, comprising a first connector 100 and at least one second connector 200. The second connector 200 is detachably connected to one side of the first connector 100, allowing the first and second connectors 100 and 200 to be disassembled and assembled. The first connector 100 includes a connection circuit board 110, which has a first connection terminal 111 and an output terminal. The first connection terminal 111 is used to connect to an onboard power source, which transmits electricity to the connection circuit board 110, which then transmits the current to the output terminal. The output terminal can be a data cable with a charging plug, or it can be equipped with a USB port or a Type-C port, allowing other electronic devices to be charged through the output terminal. The second connector 200 includes a retractable cable 210. The end of the cable 210 extends from the second connector 200 and is connected to a connector 211. The connector 211 is used to connect to the electronic device to be charged. The retractable connecting wire 210 is wound on a winding drum arranged in the second connector 200 to realize the winding of the connecting wire. The structure of the winding drum is a well-known technology in the field and is not described in detail in this embodiment. The second connector 200 is also provided with a second connection end 201 electrically connected to the connecting wire 210. The second connection end 201 is used to connect to the vehicle power supply or to be pluggable with the connection circuit board 110. When there are multiple power ports at the same position of the vehicle power supply, the second connection end 201 can be directly connected to the power port of the vehicle power supply; if there are no multiple power ports on the vehicle power supply, the second connection end 201 can be directly connected to the first connector 100, specifically, it can be connected to the output end of the first connector.

[0032] The detachable car charger of the above embodiment adopts a first connector 100 and one or more second connectors 200 to assemble into an integral structure, thereby enabling the car charger to expand multiple power ports to meet the charging needs of more electronic products. In addition, the second connector 200 is provided with a connecting cable that can be stretched and retracted, so the connecting cable 210 can be pulled out of the second connector 200 for use, which is convenient for users. Assembling the first connector 100 and the second connector 200 into a one-day structure facilitates the placement of the car charger and avoids the problem of clutter caused by multiple car chargers. Furthermore, when a structure in the first connector 100 or the second connector 200 of this detachable car charger is damaged and cannot be used, the first connector 100 or the second connector 200 can be replaced separately, which can reduce the cost of replacement for the user. In addition, users can choose a second connector 200 with different connectors to combine with the first connector 100 according to their needs, increasing versatility and meeting user needs.

[0033] 1, 3, and 6, the first connector 100 includes a first housing 120, with the connecting circuit board 110 disposed within the first housing 120. The second connector 200 includes a second housing 220, with the connecting wire 210 retracted within the second housing 220. When the second connector 200 is assembled with the first connector 100, the second housing 220 is assembled with the first housing 120.

[0034] Further, referring to Figures 2, 4, and 5, a slide groove 121 is provided on one side of the first housing 120, and a retaining groove 122 is provided on the sidewall of the slide groove 121. A slide platform 221 is provided on one side of the second housing 220, and a retaining portion 222 extends from the sidewall of the slide platform 221. When the slide platform 221 slides into the slide groove 121, the retaining portion 222 is retained within the retaining groove 122. When the second housing 220 is assembled with the first housing 120, the slide platform 221 slides into the slide groove 121, and the retaining portion 222 slides into the retaining groove 122, thereby assembling the second housing 220 with the first housing 120. Furthermore, retaining grooves 122 are provided on both sides of the slide groove 121, and retaining portions 222 are provided on both sides of the slide platform 221. This provides a more stable connection between the second housing 220 and the first housing 120 when the two are assembled.

[0035] Furthermore, the chute 121 is closed at one end and open at the other. The closed end of the chute 121 serves to position the end of the slide 221. The chute 121 also has protrusions 123 on both sides of the chute, and grooves 223 are provided on both sides of the slide 221 to retain the protrusions 123. When the slide 221 is assembled into the chute 121, the protrusions 123 snap into the grooves 223, securing the second housing 220 to the first housing 120 and preventing loosening.

[0036] 1 to 3 , the connection circuit board 110 is provided with an adapter 112, which extends from the first housing 120 and is configured to connect to the second connection end 201. In this embodiment, after the second connector 200 is assembled with the first connector 100, the second connection end 201 is connected to the adapter 112. Therefore, even after the first connection end 111 of the first connector 100 is connected to the vehicle power supply, power can be directly supplied to the second connector 200.

[0037] Further, referring to Figure 4, an embodiment of an adapter 112 and the connection method between the second connection end 201 and the adapter 112 are shown. Specifically, the adapter 112 is a female connector that connects to the first housing 120. The second connection end 201 includes an adapter cable 201a and a male connector 201b. One end of the adapter cable 201a is connected to the connecting cable 210, and the other end is connected to the male connector 201b, which is connected to the female connector. After the second connector 200 is assembled with the first connector 100, the male connector 201b is connected to the female connector, achieving electrical connection between the second connector 200 and the first connector 100.

[0038] 5 , another embodiment of the adapter 112 is shown. Specifically, the adapter 112 is a contact disposed on one side of the first housing 120. The second connection end 201 includes a pin, one end of which is electrically connected to the connection line 210, and the other end extends from the side wall of the second housing 220. When the second housing 220 is assembled with the first housing 120, the pin contacts and is electrically connected.

[0039] Further, referring to FIG. 1 , the USB interface and the Type-C interface forming the output end are arranged on the top side of the first housing 120 , which facilitates the connection of other power connection devices.

[0040] Further, referring to Figure 1, the second connectors 200 are in two groups and are detachably connected to both sides of the first connector 100; an adapter 112 is provided on the bottom side of the first connector 100, and a second connection end 201 of the second connector 200 is connected to the adapter 112.
