[0025] Example

[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides an on-board charger extension structure, including:

[0027] The charging assembly 100 includes a base 101, a housing 102 hinged to the end of the base 101, a connector 103 hinged to the end of the housing 102, a main board 104 fixedly connected inside the housing 102, and a wireless charging board 105 encapsulated in the side wall of the housing 102. The wireless charging board 105 is electrically connected to the main board 104 via a wire.

[0028] The extension component 200 includes a locking block 201 that is inserted into the end of the connector 103, a support ring 202 that is fixedly connected to the middle of the locking block 201, a watch connector 203 that is fixedly connected to the top of the support ring 202, and an earphone connector 204 that is fixedly connected to the middle position inside the support ring 202.

[0029] The base 101 serves as the foundation of the entire vehicle charger expansion structure. The housing 102 can rotate at a certain angle along the end of the base 101, allowing users to adjust the orientation of the charging components according to the vehicle's interior space layout and usage needs. The hinged structure with the housing 102 allows the connector 103 to move within a certain range, further increasing the adjustability of the charging components and creating more favorable angle adjustment conditions for subsequent connection of expansion components. The main board 104 manages and distributes power and controls the working status of the wireless charging board 105, which uses the principle of electromagnetic induction to charge devices that support wireless charging. When a device with wireless charging capability is placed near the wireless charging board 105, the magnetic field generated by the wireless charging board 105 induces a current in the receiving coil of the device, thereby charging the device. Alternatively, the interface attached to the side wall of the housing 102 can be used with a charging cable to charge the device. The main board 104 can be powered by its own battery or connected to the vehicle's power supply for charging. The support ring 202 is fixedly connected to the middle of the locking block 201, serving to support and connect other components. A watch connector 203 is fixedly connected to its top, and an earphone connector 204 is fixedly connected to its inner middle position, which are used to place and connect small electronic devices such as watches and earphones.

[0030] Specifically, the expansion component 200 also includes a connector socket 205 encapsulated on the top of the housing 102, and a connector plug 206 encapsulated inside the support ring 202. The connector plug 206 is used in conjunction with the connector socket 205. The end of the connector socket 205 extends to the side wall of the connector 103. One set of connector plugs 206 is engaged in the middle of the watch connector 203, and the other set of connector plugs 206 is engaged in the middle of the headphone connector 204.

[0031] The connection between connector plug 206 and connector socket 205 enables power circulation between the charging component and the expansion component, allowing the power of the charging component to be transmitted to watch connector 203 and headphone connector 204 to charge the connected watches, headphones and other devices.

[0032] Furthermore, the lower side wall of the support ring 202 is provided with a latch structure that works in conjunction with the end latch of the latch block 201, and the end latch of the latch block 201 is tightly engaged with the inside of the latch of the support ring 202.

[0033] This snap-fit ​​connection method ensures a secure connection between the expansion component and the charging component, and allows for easy disassembly when necessary.

[0034] Preferably, the charging assembly 100 also includes a knob 106 threaded to the side wall of the housing 102, with the end of the knob 106 threaded to the side wall of the base 101.

[0035] When it is necessary to fix the relative angle between the housing 102 and the base 101, rotate the knob 106 to lock the two at the required angle using the tightening action of the thread.

[0036] It should be noted that the charging assembly 100 also includes a button 107 that is inserted into the middle side wall of the housing 102, and the button 107 makes elastic contact with the button on the side wall of the motherboard 104.

[0037] Users can press button 107 to trigger corresponding function buttons on the motherboard 104, such as controlling the charging switch and switching charging modes.

[0038] Preferably, the side wall of the housing 102 is provided with a sound venting hole structure that works in conjunction with the motherboard 104, and the bottom of the base 101 is attached with a double-sided adhesive pad.

[0039] The sound vent structure ensures that the sound-generating components integrated on the motherboard 104 can produce sound normally, and also increases the heat dissipation capacity of the motherboard 104 to keep the charger running normally.

[0040] In use, the base 101 is fixed in a suitable position inside the vehicle using the double-sided adhesive pads on the bottom. Depending on the vehicle's interior space and usage needs, the angle between the housing 102 and the base 101 is adjusted by rotating the knob 106, facilitating the position and orientation of the wireless charging pad 105 for charging wirelessly-enabled devices such as mobile phones. When the user places a wirelessly-enabled device near the wireless charging pad 105, the mainboard 104 controls the wireless charging pad 105 to start operating, charging the device using electromagnetic induction. For operational control, such as switching the charging function on and off, the user can press the button 107. The button 107 makes elastic contact with the button on the side wall of the mainboard 104, triggering the corresponding control signal. The mainboard 104 then executes the corresponding operation based on the received signal.

[0041] When charging the watch or headphones, align the latch at the end of the expansion component 201 with the bayonet structure on the lower side wall of the support ring 202, insert it, and lock it in place to connect the expansion component to the connector 103 of the charging component. At this time, the connector plug 206 inside the support ring 202 will accurately mate with the connector socket 205 on the top of the housing 102, completing the electrical connection. Power from the charging component is transmitted to the expansion component through the connector socket 205 and the connector plug 206. When the user places the watch on the watch connector 203 and the headphones on the headphone connector 204, power is supplied to the watch and headphones through the connection lines between the watch connector 203 and the headphone connector 204 and the connector plug 206.

[0042] In summary, this device features wireless charging for convenient charging of wirelessly compatible devices like smartphones, and also provides wired charging for small electronic devices such as watches and earphones via an expansion module, meeting the charging needs of various devices within the vehicle. The entire charging assembly can be flexibly adjusted in position and orientation to suit different interior layouts and user habits, enhancing ease of use. It also provides additional charging ports for passengers, allowing for simultaneous charging of multiple devices and improving the practicality of the onboard charger.
