Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive electronic equipment technology, and in particular to an on-board charging module integrated into an automotive interior panel. Specifically, this utility model relates to an automotive charging module with a threaded interface, which has both mechanical fixing and electrical transmission functions, providing a stable mounting base and power supply for detachable wireless charging brackets, mobile terminals, or other on-board peripherals, thus achieving a simple and efficient charging solution that integrates with the automotive interior. Background Technology
[0002] With the widespread use of smartphones, tablets, and other mobile devices, the demand for charging and mounting equipment in cars is increasing. Traditional in-car charging methods mainly rely on the car's cigarette lighter socket or a dedicated USB port to power devices via wired connections. While simple and practical, this method suffers from problems such as messy cables, poor interface compatibility, and unstable installation. In recent years, wireless charging technology has been introduced into the in-car environment, improving aesthetics and convenience to some extent, but improvements are still needed in terms of mounting methods and electrical transmission integration.
[0003] In the prior art, reference document 1, CN 204407953 U, discloses a "vehicle-mounted wireless charging bracket". This bracket includes a charging body that matches the car's cigarette lighter socket, connected to a wireless charging base via a hollow metal flexible tube, supporting wireless charging functionality, and equipped with a clamping part and an anti-slip pad to secure the mobile terminal. Although this design avoids the clutter of wired connections, its fixing method relies on the clamping structure and flexible tube adjustment, is not integrated with the car panel, and electrical transmission is still achieved through internal wires, lacking an integrated solution for mechanical fixing and electrical transmission.
[0004] Prior to document 2, CN 217903630 U discloses a "car mobile phone connection device," which achieves mechanical fixation and electrical connection of a mobile phone holder by setting external threads, bayonet slots, or screw holes on a USB or cigarette lighter socket, and using a plug with a locking cap or screw. This device supports wired charging, wireless charging, and NFC communication, and can be integrated into various locations such as the car dashboard and ceiling, improving installation flexibility and connection reliability. Furthermore, the design uses a rubber ring seal to achieve waterproofing and dustproofing, enhancing environmental adaptability. While it represents progress in combining mechanical fixation and electrical transmission, its complex structure and reliance on multiple locking methods (threads, bayonet slots, screws, etc.) for compatibility, and it does not propose a unified and simple threaded interface standard to achieve a high degree of integration between fixation and charging functions.
[0005] In summary, the existing vehicle charging interfaces have the following shortcomings:
[0006] 1. Most designs still use a split structure, such as wired connection and external bracket, which fails to achieve the integration of mechanical fixation and electrical transmission, resulting in complicated installation and unreliable connection.
[0007] 2. As shown in Comparison Document 2, although it has multiple locking mechanisms, its structure is cumbersome, its applicable scenarios are limited, and it has not formed a standardized interface, which is not conducive to large-scale promotion and use.
[0008] 3. Most existing brackets or sockets are externally mounted, which affects the aesthetics of the car interior and fails to integrate deeply with the car panel, making it difficult to meet the requirements of modern car interiors for simplicity and integrity. Utility Model Content

[0041] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0042] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.
[0043] like Figures 1 to 9 As shown, this embodiment provides a threaded vehicle-mounted integrated charging module 100. The module 100 is installed in a preset installation opening in the vehicle panel 101 to provide mechanical fixation and power connection for the wireless charging bracket 60 or other peripherals.
[0044] The vehicle-mounted integrated charging module 100 includes a housing 10, an electrical connection component 20, an insulating plastic body 30, an electrical interface 40, a sealing plug 70, and a status indicator, etc.
[0045] like Figures 2 to 5 As shown, the housing 10 includes: a bottom wall 11, a peripheral side wall 12 extending upward around the bottom wall 11, and a cover 14 covering the top of the peripheral side wall 12. The bottom wall 11 and the peripheral side wall 12 form an inner cavity for accommodating the insulating plastic body 30. The peripheral side wall 12 is provided with an alignment opening 13 for mating with the insertion hole 41 on the insulating plastic body 30 and the insertion female terminal 50 inside the vehicle.
[0046] The opposite sides of the peripheral sidewall 12 extend upward to form an anti-detachment wall 123, the height of which is configured to fit tightly against the inner surface of the vehicle panel 101 during module installation, preventing the module from falling outward and improving overall stability.
[0047] The cover 14 is engaged and positioned with the connecting lug 121 on the peripheral sidewall 12 via the snap-fit part 142. The horizontal projected area of the cover 14 is slightly larger than the opening defined by the peripheral sidewall 12, so that it can cover the outside of the vehicle panel 101 after installation, thereby forming a flatter and more aesthetically pleasing appearance. The cover 14 is provided with a through hole 141 for the threaded end of the external wireless charging bracket 60 to pass through.
[0048] When the external device is not installed, the plug hole 141 can be sealed by the removable threaded sealing plug 70 to achieve the effects of dustproof, waterproof and prevent foreign objects from entering.
[0049] like Figure 7 and Figure 8 As shown, the electrical connection assembly 20 includes: a metal part 21 (positive electrode + mechanical threaded connector).
[0050] First PIN 22 (negative terminal), second PIN 23. The metal part 21 has an internally threaded through hole, which serves as the screw-in connection for the external wireless charging bracket 60 and also as the conductive path for the vehicle's positive power supply. The lower end of the metal part 21 has a square connecting block 211 for soldering the C-shaped connection v of the first PIN 22.
[0051] The first PIN pin 22 has a bent structure, and its first end is welded to the connecting block 211 through a C-shaped connector v, so that the metal part 21 is electrically connected to the first PIN pin 22, and the second end of the first PIN pin 22 extends into the socket 41.
[0052] The second PIN 23 also has a bent structure, with a top plate r at its upper end, located directly below the internal threaded through hole. When the bracket 60 is tightened, the negative terminal connection can be achieved through the top plate r.
[0053] like Figure 6 As shown, the insulating plastic body 30 encapsulates the metal part 21, the first PIN pin 22, and the second PIN pin 23 inside by injection molding, while exposing the upper end face of the metal part 21 and the second end of the PIN pin to the outside, so as to achieve contact between the bracket or to plug into the vehicle's female connector 50.
[0054] The insulating plastic body 30 has a columnar structure and fits into the inner cavity of the housing 10, which helps to improve assembly stability and insulation performance.
[0055] The electrical interface 40 is located on the side of the insulating plastic body 30, and a socket 41 is formed inside it. The socket 41 is used to accommodate the second ends of the first PIN pin 22 and the second PIN pin 23, thereby achieving a stable electrical connection with the plug-in female terminal 50 arranged inside the vehicle.
[0056] Preferably, a status indicator (e.g., LED) is provided on the outside of the module to visually indicate whether the module is powered on or connected to a load, thereby improving the ease of operation for users.
[0057] In the actual assembly process, the metal part 21, the first PIN pin 22, and the second PIN pin 23 can be placed in the preset positions in the injection mold. An insulating plastic body 30 is formed by injection molding, which encapsulates the metal part and the PIN pin structure inside. Then, the insulating plastic body 30 is placed into the inner cavity of the housing 10; then, the cover 14 is fastened and fixed to the connecting lug 121 on the peripheral side wall 12; next, the decorative ring k is installed on the outside of the cover 14 to make the appearance consistent with the vehicle interior.
[0058] Finally, the assembled charging module 100 is inserted into the mounting opening from the outside of the vehicle panel 101, so that the anti-detachment wall 123 is secured against the inside of the panel. The plug-in female terminal 50 arranged inside the vehicle is inserted into the alignment opening 13 and mates with the socket 41 to provide power.
[0059] When the user needs to install the wireless charging bracket 60, unscrew the sealing plug 70; insert the threaded end of the wireless charging bracket 60 into the insertion through hole 141 from the outside of the vehicle panel 101; screw it in and tighten it into the internal thread through hole of the metal part 21; the end of the bracket contacts the top piece r of the second PIN pin 23 to achieve negative conduction; the positive conduction path is achieved through the metal part 21; the status indicator lights up, indicating that the bracket has been correctly installed and powered.
[0060] At this time, the bracket 60 provides a stable mechanical fixation through threads, and the circuit is automatically connected, allowing the user to directly place the phone on the bracket for wireless charging.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Similarly, "first" and "second" are only for ease of understanding and have no other directional meaning, and cannot be considered as limitations on this utility model.
