[0025] 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.
[0026] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other.
[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.
[0028] Reference Figure 1 and Figure 2 This utility model provides a charging dock module assembly, comprising:
[0029] The base housing includes an upper shell 1 and a lower shell 3, which are detachably connected and together form an internal cavity;
[0030] The outer surface of the upper shell 1 is provided with a boss 11, and a plurality of through holes 13 are provided on the boss 11;
[0031] Circuit board 2 is installed inside the built-in cavity;
[0032] The circuit board 2 is provided with a first connector 21, which includes a plurality of pins 23. The ends of the pins 23 pass through the through hole 13 and protrude from the surface of the boss 11.
[0033] Specifically, in this embodiment of the utility model, in response to the technical problems of inconsistent charging dock structures, poor compatibility, long development cycles, and high costs in the market, a modular and standardized ejector pin contact design is adopted. This avoids the cumbersome process of repeatedly opening molds and designing dedicated interfaces for different devices, and solves the core pain points of physical interface mismatch and unstable electrical connection between different devices. It achieves comprehensive benefits such as rapid adaptation to multiple devices, reduced unit cost, and shortened R&D cycle, while reserving a unified hardware platform for future product function expansion.
[0034] More specifically, the boss 11 is provided with four through holes 13, which are used to accommodate the four pins 23 of the first connector 21. The four pins 23 are arranged in a rectangular shape. This layout conforms to the standard spacing of charging contacts of most commercial PADs and other devices, and provides good mechanical stability and electrical contact reliability.
[0035] In a preferred embodiment of this utility model, the ejector pin 23 is a retractable POGO PIN.
[0036] Specifically, in this embodiment of the invention, a retractable POGO PIN is selected as the ejector pin 23. Its internal structure typically includes a spring, allowing the ejector pin 23 to retract when subjected to external pressure and rebound after the pressure is released, maintaining a stable and reliable elastic contact with the device's charging contacts. This design effectively compensates for assembly tolerances and minor deformations between the device and the charging dock, reducing charging failures caused by poor contact. It also significantly reduces physical wear on the device interface from repeated insertions and removals, extending the lifespan of both. This design is particularly suitable for charging commercial handheld electronic products that require frequent placement and removal.
[0037] In a preferred embodiment of the present invention, the boss 11 and the upper shell 1 are integrally injection molded.
[0038] Specifically, in this embodiment of the utility model, the boss 11 is formed synchronously with the upper shell 1 through an integral injection molding process. Its overall shape is rectangular, and its size is precisely designed to ensure the accurate alignment and stable support of the ejector pin 23. This design not only enhances the structural strength and overall aesthetics of the boss 11, but also eliminates the subsequent assembly process, effectively improving production efficiency and product consistency.
[0039] In a preferred embodiment of the present invention, the circuit board 2 is further provided with a second connector 22, and the side wall of the lower shell 3 is provided with a clearance opening 31 that matches the second connector 22.
[0040] Specifically, in this embodiment of the present invention, the second connector 22 is disposed on the lower end face of the circuit board 2 near the right short side. This arrangement makes the interface direction of the second connector 22 consistent with the opening direction of the clearance port 31, so that after the housing is assembled, the socket of the second connector 22 can be fully exposed on the side of the housing, making it convenient for the user to directly plug in the external power cord from the right side of the device.
[0041] In a preferred embodiment of this utility model, the second connector 22 is a DC power socket or a USB Type-C socket.
[0042] Specifically, in this embodiment of the invention, by selecting a universal and powerful standard interface such as a DC power socket or USB Type-C as the second connector 22, the charging dock module can not only charge specific devices through the pins 23, but also be used as a universal power adapter or data transmission hub.
[0043] For example, when the second connector 22 is a DC socket, it can be connected to an external regulated power supply to provide higher power input to the built-in circuits and devices; when it is a USB Type-C socket, it can receive power input to charge itself, and can also serve as a host port to power other peripherals or perform data synchronization, which greatly expands the application scenarios and functional flexibility of the module assembly, while conforming to the mainstream interface standards in the market and improving user convenience.
[0044] In a preferred embodiment of the present invention, the first connector 21 and the second connector 22 are electrically connected through the circuit board 2.
[0045] Specifically, in this embodiment of the invention, the pins 23 of the first connector 21 and the corresponding pins of the second connector 22 are electrically interconnected through wires printed on the circuit board 2, forming a complete current distribution and signal transmission path. After the product is placed in the seat slot, the PAD bracket holds the PAD, and the charging end of the PAD contacts the pin of the boss. After the second connector 22 is connected to an external power port, such as a car power interface, the power input from the external power source enters the circuit board 2 through the second connector 22. After being processed by its internal voltage conversion, overcurrent protection, and intelligent identification circuit, it is distributed to each pin 23 of the first connector 21, thereby safely and efficiently charging the PAD. This integrated circuit design not only achieves reliable energy transmission but also supports multiple fast charging protocols through programming, automatically adapting to the charging needs of different devices, greatly improving charging efficiency and user experience.
[0046] In a preferred embodiment of the present invention, the upper shell 1 is provided with a slot 12, and the lower shell 3 is provided with a buckle 32;
[0047] During installation, the buckle 32 engages with the slot 12 to fix the upper shell 1 and the lower shell 3 together.
[0048] Specifically, in this embodiment of the invention, the slot 12 is disposed around the perimeter of the upper shell 1 and extends downwards, and the buckle 32 is configured as an elastic barb structure corresponding to the position of the slot 12 and distributed on the outer side wall of the lower shell 3. During installation, by aligning and pressing the upper shell 1 and the lower shell 3, the buckle 32 of the lower shell 3 is compressed and undergoes elastic deformation until it is inserted into the slot 12 of the upper shell 1 and returns to its original shape, thereby achieving a tight engagement and fixation between the two. This circumferentially distributed buckle-slot structure replaces the traditional screw connection, which not only enables rapid assembly and disassembly of the shell and improves production efficiency, but also avoids externally visible screw holes, making the product appearance more concise and beautiful, while ensuring the firmness and sealing of the shell connection.
[0049] In a preferred embodiment of the present invention, a plurality of rubber plugs 5 are also embedded on the outer surface of the upper shell 1, and the rubber plugs 5 are distributed around the boss 11.
[0050] Specifically, in this embodiment of the present invention, the rubber plugs 5 are evenly distributed around the protrusions 11. When a device such as a PAD is placed on the charging dock, the bottom of the device first contacts the rubber plugs 5 and compresses them to produce deformation. This not only effectively buffers the impact force when the device is placed and protects the device shell from scratches, but also ensures the precise alignment and stable contact between the device charging interface and the ejector pin 23 through the elastic deformation of the rubber plugs 5. At the same time, the anti-slip properties of the rubber plugs 5 enhance the stability of the device after placement, avoid charging interruption caused by accidental slippage, and improve the reliability of the charging process and user experience.
[0051] In a preferred embodiment of this utility model, the circuit board 2 is fixed to the lower shell 3 by screws 4.
[0052] Specifically, in this embodiment of the invention, the inner bottom surface of the lower shell 3 is provided with multiple positioning pins with internal threads, and the circuit board 2 has through holes corresponding to the positioning pins. During assembly, the circuit board 2 is placed inside the lower shell 3, aligning its through holes with the positioning pins. Then, screws 4 are passed through the through holes of the circuit board 2 and screwed into the internal threads of the positioning pins, thereby securely mounting the circuit board 2 onto the lower shell 3. This fixing method is simple in structure and reliable in connection. It not only effectively prevents the circuit board 2 from loosening or shifting within the shell, ensuring the alignment accuracy between the ejector pin 23 and the through hole 13, and the mating relationship between the second connector 22 and the clearance opening 31, but also facilitates production assembly and subsequent maintenance disassembly.
[0053] In a preferred embodiment of this utility model, the circuit board 2 is a printed circuit board assembly.
[0054] Specifically, in this embodiment of the invention, the printed circuit board assembly (PCBA) integrates a power management module, a signal conditioning circuit, and necessary passive components. The first connector 21, the second connector 22, and other electronic components are densely integrated onto the same board using surface mount technology (SMT). This highly integrated design not only optimizes the internal space layout and improves circuit stability and anti-interference capabilities, but also allows for flexible functional customization and upgrades according to different charging protocols (such as PD / QC) and device requirements, providing the charging dock module with powerful core control capabilities and excellent scalability.
[0055] In summary, this utility model, through its highly modular and standardized design, successfully solves the industry pain points of poor compatibility, long development cycles, and high costs associated with traditional charging docks. This charging dock module can serve as a standard component; simply design a corresponding base housing for different electronic devices, ensuring that the structure of the charging section of the electronic device matches the charging structure of this product module. Then, assembling the charging dock module into the base housing assembles the desired charging dock. The charging dock module can be mass-produced, significantly shortening the time to market for new products, reducing development and manufacturing costs, while ensuring the reliability and consistency of core charging functions. This provides an efficient, flexible, and economical path for charging solutions for commercial handheld electronic products.
[0056] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
