Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a cigarette lighter base. Background Technology

[0002] The car cigarette lighter socket, as the standard power output port in vehicles, has long been the primary way for drivers and passengers to power in-vehicle devices. Traditional cigarette lighter sockets typically only provide a standard 12V / 24V socket, offering relatively limited functionality. With the widespread use of mobile electronic devices, users' demands for in-vehicle charging have increased dramatically and become increasingly diverse, requiring the simultaneous power supply or charging of multiple devices such as mobile phones, tablets, Bluetooth headsets, dashcams, and navigation devices, each with different interface types.

[0003] Existing technologies include some cigarette lighter docks that provide USB charging ports, but they generally suffer from limited number and types of ports. They typically only provide 1-2 USB-A ports, which is insufficient to meet the needs of charging multiple devices simultaneously. They also lack the mainstream Type-C interface, and most only provide wired charging, not wireless charging, requiring users to carry a charging cable. Furthermore, the cigarette lighter interface connection in vehicles is prone to poor contact, device slippage, or abnormal noise due to vehicle bumps or cable pulling, affecting safety and user experience. In view of this, existing technologies may already have solutions to the above problems, but this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0011] Preferably, a second rubber pad is installed at the lower end of the wireless charging base.

[0012] Preferably, the second rubber pad is a circular rubber pad.

[0013] Beneficial effects

[0014] This utility model provides a cigarette lighter base with the following advantages: By integrating two USB ports, two Type-C ports, a cigarette lighter power supply sleeve, and a wireless charging component into the mounting housing, it achieves full coverage of wired and wireless charging methods and significantly increases the number of power supply interfaces. Users can simultaneously provide power to multiple different types of devices, greatly improving charging efficiency and convenience, and meeting the needs of charging multiple devices at the same time. The two USB ports and two Type-C ports are respectively arranged on both sides of the upper wall of the mounting housing, avoiding cable tangling caused by overly concentrated interfaces, making it convenient for users to plug, unplug, and manage cables. The cigarette lighter power supply sleeve is located at the upper center, facilitating the insertion of the cigarette lighter and other vehicle devices. The wireless charging component is connected to the side wall of the mounting housing via a flexible connecting cable, allowing for flexible adjustment of the wireless charging base's position, greatly improving the practicality and user experience of wireless charging. The first and second rubber pads effectively increase the friction between the mounting housing and the wireless charging base and the vehicle's contact surface, preventing the base from sliding or shifting while the vehicle is in motion and improving placement stability.

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example: Please refer to Figure 1-3 A cigarette lighter base includes a plug 1 and a mounting housing 2. The mounting housing 2 is fixedly installed above the plug 1, and a power supply adapter structure is installed inside the mounting housing 2.

[0021] The power supply adapter structure includes: two USB ports 3, two Type-C ports 4, a cigarette lighter power supply sleeve 5, and a wireless charging component;

[0022] Both USB ports 3 are located on one side of the upper wall of the mounting box 2, both Type-C ports 4 are located on the other side of the upper wall of the mounting box 2, the cigarette lighter power supply sleeve 5 is located at the center of the upper end of the mounting box 2, and the wireless charging component is connected to the side wall of the mounting box 2.

[0023] When in use, the user inserts plug 1 into the car cigarette lighter socket. The metal electrodes inside plug 1 are connected to the vehicle's power supply. The current is transmitted through the wires inside plug 1 to the power input interface at the bottom of the mounting box 2. The current first enters the main control PCB board inside the mounting box 2. The DC-DC step-down module on the PCB board converts the input 12V / 24V high-voltage DC into 5V-15V adjustable DC, which powers the USB port 3, two Type-C ports 4, and the wireless charging component. The cigarette lighter power supply sleeve 5 is directly connected to the input power supply to power the traditional cigarette lighter device. When the cigarette lighter device is inserted into the cigarette lighter power supply sleeve 5, it directly obtains the vehicle's original voltage.

[0024] In practice, the wireless charging components include: a flexible connecting cable 6 and a wireless charging base 7.

[0025] One end of the flexible connecting cable 6 is connected to the center of the side wall of the mounting box 2, and the wireless charging base 7 is connected to the other end of the flexible connecting cable 6.

[0026] When wirelessly charging electronic devices, the mobile phone is placed on the wireless charging base 7. The coil inside the wireless charging base 7 receives the electrical energy transmitted from the PCB board and realizes electromagnetic induction charging through wireless charging control. Furthermore, through the set elastic connecting line 6, while ensuring the power supply effect of the wireless charging base 7, it can be stretched and retracted according to the position of the wireless charging base 7, reducing the space occupied by the cable group.

[0027] In the specific implementation process, an annular groove 8 is machined at the connection position between the mounting box 2 and the plug 1. Through the machined annular groove 8, when the plug 1 is inserted into the vehicle socket, it can wrap the annular protrusion at the top of the vehicle socket. On the one hand, it increases the insertion stability of the plug 1, and on the other hand, it reduces the distance between the mounting box 2 and the vehicle, ensuring the contact effect between the first rubber pad 9 at the lower end of the mounting box 2 and the vehicle.

[0028] In the specific implementation process, first adhesive pads 9 are installed on both sides of the lower end of the mounting box 2. The two first adhesive pads 9 can be used to bond the lower sides of the mounting box 2 to the vehicle, ensuring the installation stability of the mounting box 2, thereby ensuring the connection strength of the plug 1 to the socket and preventing loosening and charging failure.

[0029] In the specific implementation process, a second adhesive pad 10 is installed at the lower end of the wireless charging base 7. The second adhesive pad 10 can be used to bond and fix the wireless charging base 7, ensuring the installation stability of the wireless charging base 7.

[0030] In the specific implementation process, the second adhesive pad 10 is a circular adhesive pad. The use of a circular adhesive pad can effectively increase the bonding area between the wireless charging base 7 and the vehicle.

[0031] Although embodiments of the present invention have been shown and described, 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.
