Description

Technical Field

[0001] This utility model relates to the field of wireless charging technology, specifically to an on-board charging device with a tail control module. Background Technology

[0002] Wireless charging technology delivers power through a contactless electromagnetic energy transfer mechanism. Its core lies in the coupling of an alternating magnetic field between the transmitting and receiving units for energy transfer. This technology eliminates the repeated plugging and unplugging of physical interfaces in traditional charging methods, reducing mechanical wear and tear and extending the service life of the device's charging structure. It is particularly suitable for portable electronic devices requiring high-frequency charging, such as smartphones and wireless headphones. Since current mainstream wireless charging devices are typically magnetic or non-magnetic, current wireless charger architectures employ both magnetic and non-magnetic coil configurations.

[0003] However, traditional wireless charging devices suffer from significant limitations in functional expandability. Their fixed, integrated design prevents flexible configuration and future upgrades of functional components within limited installation space. Charging devices typically only have a charging interface, lacking standardized expansion interfaces. This prevents users from freely adding or replacing functional modules based on actual usage scenarios (such as integrating physical air conditioning buttons, multiple types of fast charging interfaces, data transmission modules, and expansion control modules in a vehicle environment). This structural limitation forces consumers to connect independent accessories or replace the entire device to obtain additional functionality, resulting in cluttered vehicle interiors, tangled cables, increased usage costs, and wasted resources. Furthermore, the non-replaceable nature of the functional hardware means that partial damage necessitates the complete device's disposal. Moreover, designing different expansion modules for different usage scenarios requires separate mold production, leading to high costs and contradicting sustainable design principles, while also significantly increasing subsequent maintenance costs. Utility Model Content

[0004] (I) Technical problem to be solved: In view of the shortcomings of the existing technology, this utility model provides a vehicle charging device with a tail control module, which has the advantages of strong functional expandability and convenient disassembly and assembly, and solves the problem of the single function of traditional charging equipment and the high cost of expansion and modification.

[0005] (II) Technical Solution: To achieve the above-mentioned purpose of strong functional expandability and convenient disassembly and assembly, this utility model provides the following technical solution: A vehicle-mounted charging device with a tail control module includes a housing and a base fixed inside the housing. A wireless charging module is provided inside the housing. The wireless charging module includes a lifting coil and a sliding coil. The lifting coil is installed on the base and connected by a lifting rod. The sliding coil is also slidably installed on the base and connected by a sliding bracket. The sliding bracket is fixedly connected to the sliding coil and slidably cooperates with the lifting coil. When the sliding bracket moves laterally, it drives the lifting coil to move longitudinally along the lifting rod, so that the lifting coil and the sliding coil form a spatially misaligned stack. An expansion dock for expanding the base function is fixedly installed at the bottom of the housing. An expansion hole is opened on the expansion dock. A replaceable device module is fixedly installed in the expansion hole. The device module can be a button, a charging module, or an expansion module. The bottom of the device module is connected to the housing.

[0006] Preferably, the expansion holes are provided in two or more sets, a circuit board is also installed on the base, the device module is electrically connected to the circuit board, and both the lifting coil and the sliding coil are electrically connected to the circuit board.

[0007] Preferably, the two sets of expansion holes are arranged in an equidistant array.

[0008] Preferably, the expansion dock has buckles at both ends, a charging platform for placing the device to be charged is provided on the housing, and a device slot is provided at the rear of the housing. Both sides of the device slot have locking holes. The expansion dock is embedded in the device slot, which is located at the rear of the charging platform. The device slot and the housing are integrally machined. During assembly, the expansion dock is pressed against the device slot, and the buckles deform inwards into the device slot. With continued pressing, when the buckles pass through the locking holes, the protrusions on the outer side of the buckles elastically return outwards and engage with the locking holes.

[0009] Preferably, the lifting rod is fixedly connected to the base, the lifting coil is slidably connected to the lifting rod, and a return spring is provided between the lifting coil and the lifting rod. The sliding bracket is slidably connected to the base, the sliding coil is fixedly installed on the sliding bracket, and a drive module for driving the sliding bracket to slide along the base is also fixedly installed on the base.

[0010] Preferably, the bottom of the device module is provided with a module carrier plate, and the device module is electrically connected to the circuit board through the module carrier plate. Both ends of the module carrier plate are snapped into the expansion holes.

[0011] Preferably, the drive module includes a drive motor and a slide bar, the sliding bracket is connected to the slide bar, the drive motor drives the slide bar to slide in a direction, the drive motor is fixedly installed in the base, and when the slide bar slides, it drives the sliding bracket to move accordingly.

[0012] Preferably, the slide rod passes through the equipment slot, and the bottom of the expansion dock has a clearance groove that matches the movement trajectory of the slide rod to avoid interference. When the sliding bracket slides towards the expansion dock, the end of the slide rod can be accommodated in the clearance groove.

[0013] Preferably, the clearance groove is formed between the two sets of expansion holes.

[0014] Preferably, a clearance hole matching the movement trajectory of the slide bar is provided at the equipment slot. The clearance hole and the clearance groove of the expansion dock are coaxially arranged. When the slide bar moves towards the expansion dock, it passes through the clearance hole and the clearance groove in sequence to form a continuous clearance channel.

[0015] (III) Beneficial Effects: Compared with the prior art, this utility model provides a vehicle-mounted charging device with a tailgate control module, which has the following beneficial effects:

[0016] 1. This vehicle-mounted charging device with a tailgate control module, through the cooperation of an expansion dock structure and a device module, enables convenient replacement of charging equipment functions. The expansion dock adopts a modular snap-fit ​​assembly structure, allowing users to disassemble the entire expansion dock unit simply by pressing the snaps. Functional components such as buttons, fast charging interfaces, or data transmission modules can be freely replaced through expansion holes. Furthermore, the device module establishes an electrical connection with the circuit board via a module carrier board, enabling plug-and-play functional expansion. This overcomes the limitations of traditional single-function charging devices, allowing users to flexibly configure device functions according to scenario requirements, greatly improving product customizability and lifespan. Simultaneously, this structure decouples traditional integrated functional hardware into replaceable, independent, standardized components, significantly reducing the demand for customized parts due to functional differences during production, thereby reducing manufacturing costs. The device module also supports on-demand function configuration, avoiding the pre-installation costs of redundant functional hardware. Moreover, when a partial function fails, only the corresponding module needs to be replaced, rather than the entire device, significantly reducing overall production, inventory, and maintenance costs.

[0017] 2. This vehicle-mounted charging device with a tail control module utilizes a combination of a clearance slot structure, a sliding coil structure, and a lifting coil structure to achieve dynamic adaptation of the spatially staggered stacking of dual coils to meet the charging needs of magnetic and non-magnetic devices. For magnetic devices, the lifting coil is directly activated, while for non-magnetic devices, a linkage mechanism is used to laterally move the sliding coil to form a non-magnetic working mode. Furthermore, during the resetting process of the sliding bracket, the clearance hole and clearance slot can form a coaxial and continuous clearance channel, allowing the slide rod to be completely accommodated in the clearance slot of the expansion dock during lateral displacement. This ensures that the slide rod can avoid the installation area of ​​the device module during movement, eliminating interference between the slide rod and the expansion dock. It achieves coordinated operation of mechanical movement and modular functions within a limited space, greatly improving the utilization rate of the internal space of the device, effectively reducing the size of the device, and avoiding component damage caused by structural collisions.

[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] Example 1: Please refer to Figure 1 , Figure 2 and Figure 5 A vehicle-mounted charging device with a rear control module includes a housing 1 and a base 2 fixed within the housing 1. An expansion dock 5, which extends the functionality of the base 2, is fixedly installed at the bottom of the housing 1. The expansion dock 5 has an expansion hole 51, within which a replaceable device module 6 is fixedly installed. The expansion dock 5 serves as a functional extension of the base 2, allowing users to flexibly add or replace functional components, such as buttons or charging interfaces, according to their actual needs by providing the expansion hole 51 and the replaceable device module 6. This structure solves the problem of limited functionality in traditional wireless charging devices, allowing users to adapt to different scenarios without replacing the entire device, thereby improving product customizability and lifespan. Simultaneously, the modular design reduces production complexity and the need for customized components due to functional differences, comprehensively reducing manufacturing and maintenance costs. The device module 6 can be an expansion component, including modules such as buttons and charging modules. The bottom of the device module 6 is connected to the housing 1. This allows for the coverage of diverse user needs, such as integrating driving control or fast charging functions within a limited space. The connection between the bottom of the device module 6 and the housing 1 ensures the mechanical stability and overall integration of the module. This design enables plug-and-play functional expansion, allowing users to quickly replace modules to adapt to different tasks and avoiding the pre-installation costs of redundant hardware. Meanwhile, the connecting housing 1 provides physical support to prevent modules from loosening during operation, enhancing the reliability and durability of the device.

[0027] Please see Figures 1-3The expansion holes 51 have two or more sets, supporting the simultaneous installation of multiple device modules 6 and expanding the device's functional versatility. This design allows users to integrate multiple components on a single docking station 5, such as simultaneously configuring buttons and charging interfaces to meet the needs of complex application scenarios. By increasing the number of expansion holes 51, the device's functional scalability is significantly improved, optimizing internal space utilization, avoiding single-function limitations, and reducing the cost of additional equipment required for added functionality. A circuit board 21 is also mounted on the base 2, and the device modules 6 are electrically connected to the circuit board 21. This design enables plug-and-play functionality; modules can be replaced and immediately put into operation without reconfiguration or rewiring. The standardized interface simplifies the installation process, improves device reliability and response speed, and supports modular expansion, reducing the need for circuit modifications due to functional changes. The two sets of expansion holes 51 are arranged in an equidistant array. This equidistant arrangement ensures the symmetrical distribution of modules on the docking station 5, avoiding installation conflicts and improving overall aesthetics. This design facilitates standardized user operations, such as quick alignment and securing of modules, reducing installation errors. Meanwhile, the array layout improves internal space utilization, ensures that multiple modules work together without interference, and enhances the stability and functionality of the device. Please refer to [link / reference]. Figure 1 and Figure 5The housing 1 houses a wireless charging module and a charging platform for placing the device to be charged. The docking station 5 has latches 52 at both ends, and a device slot 11 is located at the rear of the housing 1, integrally machined with the housing 1. Both sides of the device slot 11 have locking holes 12, allowing the docking station 5 to be fitted into it. This design simplifies the installation process; users only need to align the docking station to secure it without additional tools. The fitted structure also protects internal components from external impacts, improving the overall protection and lifespan of the device. During assembly, pressing the docking station 5 into the device slot 11 causes the latches 52 to deform inwards and enter the slot. Continuing to press, as the latches 52 pass the locking holes 12, the outer protrusions of the latches 52 elastically return to their original position and engage with the locking holes 12. This intuitive and tool-free operation allows users to easily install or release the docking station 5 by hand, facilitating module replacement or maintenance. The press-and-release design reduces disassembly steps, improving user experience and operational efficiency. Meanwhile, it ensures that the expansion dock 5 can be easily removed when needed, avoiding damage caused by structural jamming and extending the service life of components. A module carrier plate 61 is located at the bottom of the device module 6. The device module 6 is electrically connected to the circuit board 21 through the module carrier plate 61, with both ends of the module carrier plate 61 snapping into the expansion holes 51. The module carrier plate 61 and circuit board 21 are electrically connected, handling power transmission and signal exchange, ensuring plug-and-play functionality. The snap-in structure at both ends of the module carrier plate 61 provides a secure mechanical fixation, preventing the module from loosening or falling off during use. This design simplifies the module installation process; users only need to insert the module to complete the connection, eliminating the need for complex wiring. At the same time, the snap-in structure enhances the reliability of the module, ensuring good electrical contact and improving the overall performance and safety of the equipment.

[0028] Example 2: Please refer to Figures 1-3The wireless charging module includes a lifting coil 3 and a sliding coil 4. The lifting coil 3 is mounted on a base 2 and connected via a lifting rod 31. The sliding coil 4 is also slidably mounted on the base 2 and connected via a sliding bracket 41. The sliding bracket 41 is fixedly connected to the sliding coil 4 and slidably engages with the lifting coil 3. When the sliding bracket 41 moves laterally, it causes the lifting coil 3 to move longitudinally along the lifting rod 31, resulting in a spatially misaligned stacking of the lifting coil 3 and the sliding coil 4. When the device is magnetically attached, the lifting coil 3 can operate directly. When the device is non-magnetically attached, the lateral displacement of the sliding bracket 41, through the sliding engagement mechanism, causes the lifting coil 3 to move longitudinally along the lifting rod 31, resulting in a spatially misaligned stacking of the two coils. This design optimizes charging position and efficiency, ensuring the coordinated operation of the two coils within a limited space, avoiding magnetic field interference caused by coil overlap, and improving charging adaptability and device compatibility. It solves the problem that traditional wireless chargers cannot flexibly handle different device types due to their fixed coil layout. Both the lifting coil 3 and the sliding coil 4 are electrically connected to the circuit board 21. The lifting rod 31 is fixedly connected to the base 2, the lifting coil 3 is slidably connected to the lifting rod 31, and a return spring is provided between the lifting coil 3 and the lifting rod 31. The sliding bracket 41 is slidably connected to the base 2, and the sliding coil 4 is fixedly mounted on the sliding bracket 41. A drive module 7 that drives the sliding bracket 41 to slide along the base 2 is also fixedly mounted on the base 2. The lifting rod 31 is fixed to the base 2 to provide stable support, the sliding connection of the lifting coil 3 allows longitudinal movement, and the return spring ensures that the coil automatically returns to its original position when not in operation. The sliding connection between the sliding bracket 41 and the base 2 allows the sliding coil 4 to move laterally, and the drive module 7 provides power. This design controls the movement of two coils through a single drive source, reducing the number of components and potential failure points. At the same time, the return spring compensates for displacement errors, improves movement accuracy, ensures that the coil quickly returns to its original position after switching charging modes, extends equipment life, and reduces maintenance costs. The drive module 7 includes a drive motor 71 and a slide bar 72. A sliding bracket 41 is connected to the slide bar 72. The drive motor 71 drives the slide bar 72 to slide in a specific direction. The drive motor 71 is fixedly installed in the base 2. When the slide bar 72 slides, it drives the sliding bracket 41 to move accordingly. This achieves automated operation, allowing users to adjust the coil position without manual intervention, thus improving ease of use.

[0029] Please see Figures 4-6 The slide bar 72 passes through the equipment slot 11, and the bottom of the expansion dock 5 is provided with a clearance slot 53 that matches the movement trajectory of the slide bar 72 to avoid interference. Figure 4 and Figure 5As shown, when the sliding bracket 41 slides towards the expansion dock 5, the end of the sliding rod 72 can be accommodated in the clearance groove 53. The sliding rod 72 is designed to pass through the equipment slot 11 and the clearance groove 53 is opened at the bottom of the expansion dock 5 to eliminate spatial conflicts between mechanical movement and functional modules. When the sliding rod 72 moves towards the expansion dock 5, its end can be completely accommodated in the clearance groove 53. This design prevents the sliding rod 72 from colliding with the expansion dock 5 or the equipment module 6, ensuring free movement of the sliding rod 72 within a limited space. Simultaneously, it protects internal components from damage, improves equipment durability, and allows the drive module 7 to operate seamlessly during charging mode switching without affecting the replaceable functional modules of the expansion dock 5. The clearance groove 53 is located between the two sets of expansion holes 51. The clearance groove 53 is designed to be located between the two sets of expansion holes 51 to optimize spatial layout and ensure the independence of functional modules. The clearance groove 53 is located in the middle of the expansion holes 51, avoiding occupying the module installation area. This design ensures that the movement trajectory of the slide bar 72 avoids the electrical connection points of the device module 6, preventing interference with the normal operation of the module. Simultaneously, it maintains the symmetry of the expansion hole array 51, facilitating module installation and replacement, improving overall structural compactness, maximizing internal space utilization, and supporting multi-functional expansion without affecting mechanical movement. A clearance hole 13 is provided at the device slot 11 to match the movement trajectory of the slide bar 72, such as... Figure 6 As shown, the clearance hole 13 and the clearance groove 53 of the expansion dock 5 are coaxially arranged. When the slide rod 72 moves towards the expansion dock 5, it passes through the clearance hole 13 and the clearance groove 53 in sequence, forming an unobstructed channel. The purpose of this design is to ensure that the slide rod 72 is always in a clearance state throughout the entire movement, completely eliminating the risk of interference with the housing 1 or the expansion dock 5.

[0030] Working Principle: This utility model achieves dynamic wireless charging and functional expansion through mechanical linkage and modular design. The expansion dock 5 is embedded in the device slot 11 at the rear of the housing 1 via a buckle 52. Multiple expansion holes 51 allow for the insertion of replaceable device modules 6, such as physical buttons, fast charging interfaces, or data transmission modules. The module carrier plate 61 at the bottom of the device module 6 is electrically connected to the circuit board 21 on the base 2. The user can disassemble the expansion dock 5 by pressing the buckle 52 and replace the device module 6 and its carrier plate as needed.

[0031] Meanwhile, when the device needs charging, different charging coils are used depending on the device type. When the device is magnetically attached, it is charged directly through the lifting coil 3. When the device is non-magnetically attached, the drive module 7 is activated, and the drive motor 71 pushes the slide rod 72 to move laterally, causing the sliding bracket 41 and the sliding coil 4 fixed on it to move synchronously. The sliding bracket 41 and the lifting coil 3 adopt an inclined or curved sliding fit structure, so that during the lateral movement of the sliding bracket 41, the lifting coil 3 is simultaneously moved longitudinally along the lifting rod 31. During this process, the lifting coil 3 and the sliding coil 4 gradually form a spatially staggered stack, that is, staggered arrangement, with the lifting coil 3 at the bottom and the sliding coil 4 at the top, thus adapting to non-magnetically attached devices and changing the charging position of the sliding coil 4 according to the device position. The return spring ensures that the lifting coil 3 returns to its original position when the sliding bracket 41 returns to its original position.

[0032] During the resetting process of the sliding bracket 41, the slide rod 72 will move horizontally towards the tail of the housing 1, i.e., the expansion dock 5. The end of the slide rod 72 first passes through the clearance hole 13 at the equipment slot 11 of the housing 1, and then continues to be inserted into the clearance groove 53 at the bottom of the expansion dock 5. The clearance groove 53 is coaxially aligned with the clearance hole 13, forming a continuous longitudinal clearance channel. This ensures that when the slide rod 72 moves the sliding bracket 41 laterally, the end of the slide rod 72 can be completely accommodated in the cavity of the clearance groove 53, avoiding collision or motion interference between the slide rod 72 and the expansion dock 5. At the same time, the structural layout of the clearance groove 53 between the two sets of expansion holes 51 ensures that the displacement path of the slide rod 72 avoids the equipment module 6 installed in the expansion hole 51, ensuring that the coexistence of mechanical movement and functional modules does not interfere with each other.
