This overall architecture design enables the charging device to operate efficiently, stably, and safely, providing reliable charging protection for mobile devices; wherein, the vehicle in this utility model includes, but is not limited to, transportation vehicles such as cars, trucks, and motorcycles; and the battery is a DC12V or higher battery.
[0031] like Figure 2As shown, the connection assembly 20 includes a positive terminal 21, a negative terminal 22, and an ACC switch terminal 23. The positive terminal 21 is used to electrically connect to the positive terminal of the vehicle battery; the negative terminal 22 is used to electrically connect to the negative terminal of the vehicle battery; and the ACC switch terminal 23 is used to electrically connect to the vehicle's fuse box. Specifically, this design achieves a direct and reliable electrical connection with the positive and negative terminals of the vehicle battery, ensuring the stability and accuracy of the power input. The ACC switch terminal 23 is electrically connected to the vehicle's fuse box. When an overload or short circuit occurs in the circuit, the fuse 53 in the fuse box will melt, thereby cutting off the circuit and preventing damage to the charging device and the vehicle battery due to excessive current, further improving the safety of the entire charging system. This connection method complies with the specifications of the vehicle's electrical system, ensuring the compatibility and safety of the charging device with the vehicle's power system.
[0032] like Figure 2 As shown, both the positive terminal 21 and the negative terminal 22 are connected to metal clips 24. Specifically, the metal clips 24 have good conductivity and elasticity, and can be tightly clamped onto the positive and negative terminals of the vehicle battery, allowing users to quickly and easily connect the charging device to the vehicle battery without the need for complicated tools, greatly improving the efficiency of installation and removal. At the same time, the tight connection of the metal clips 24 ensures good conductivity, reduces contact resistance, avoids problems such as unstable charging due to poor contact, and improves the reliability of the charging process.
[0033] like Figure 3 As shown, a fuse assembly 50 is connected in series with the positive terminal 21. The fuse assembly 50 includes an insulating housing 51, a fuse cover 52, and a fuse 53. The insulating housing 51 is fixedly connected to the positive terminal 21. The fuse cover 52 is connected to the insulating housing 51. The fuse 53 is detachably connected to the insulating housing 51 and electrically connected to the positive terminal 21. Specifically, the fixed connection of the insulating housing 51 to the positive terminal 21 provides insulation protection for the fuse 53 and the terminals, preventing external conductive materials from contacting the internal conductive components and avoiding safety hazards such as short circuits. The fuse cover 52, connected to the insulating housing 51, provides physical protection for the fuse 53, preventing dust, moisture, etc., from entering the housing and affecting the performance of the fuse 53. Fuse 53 is detachably connected to the insulating housing 51 and electrically connected to the positive terminal 21. When fuse 53 blows due to a circuit fault, the user can easily open the fuse cover 52 to replace it with a new fuse 53 without disassembling the entire connection assembly 20, thus improving maintenance convenience. This design of the fuse assembly 50 ensures circuit safety while also facilitating routine maintenance and repairs by the user.
[0034] like Figure 3As shown, the edge of the safety cover 52 is hinged with a first flexible connecting strip 54, which is connected to the insulating shell 51. Specifically, the first flexible connecting strip 54 is typically made of a material with a certain degree of elasticity and flexibility, such as rubber or silicone. When the safety cover 52 is opened to replace or inspect the fuse 53, the flexible connecting strip keeps the cover connected to the insulating shell 51, preventing the cover from being lost. At the same time, the hinged design of the flexible connecting strip makes the opening and closing of the cover more flexible and convenient, eliminating concerns about the cover falling off or being lost, thus improving operational convenience and safety.
[0035] like Figure 2 As shown, the connection assembly 20 also includes an insulating protective sleeve 25, which is used to cover the positive terminal wire 21, the negative terminal wire 22, and the ACC switch wire 23. Specifically, the insulating protective sleeve 25 is made of a material with good insulation properties, such as polyvinyl chloride or rubber, which can effectively prevent the wires from contacting external conductive objects and avoid short circuit accidents. At the same time, the protective sleeve can also provide physical protection for the wires, preventing them from being subjected to mechanical damage such as wear and compression, thus extending the service life of the wires. In addition, the covering of the insulating protective sleeve 25 makes the wiring of the connection assembly 20 more neat and orderly, reduces mutual interference between the wires, and improves the reliability and safety of the entire charging device.
[0036] like Figure 1 As shown, the charging control module 30 has a decorative surface 31 on its upper part, which is used to display the brand logo. Specifically, the decorative surface 31 not only enhances the aesthetics of the charging device, making the product more attractive, but also strengthens brand recognition and influence by displaying the brand logo, thus contributing to the product's market competitiveness. Furthermore, the decorative surface 31 can utilize different materials and surface treatment processes, such as brushed metal or baked enamel, to further enhance the product's texture and quality, meeting diverse user demands for product appearance.
[0037] like Figure 4As shown, the charging output component 40 includes a first protective cover 41, a second protective cover 42, a USB Type-A interface 43, and a USB Type-C interface 44. The first protective cover 41 is used to cover the USB Type-A interface 43; the second protective cover 42 is used to cover the USB Type-C interface 44. The USB Type-A interface 43 and the USB Type-C interface 44 are electrically connected to the charging control module 30 via branched wires 45. Specifically, the USB Type-A interface 43 and the USB Type-C interface 44 are currently the mainstream charging interfaces for mobile devices on the market, which can meet the charging needs of most smartphones, tablets, smartwatches, and other mobile devices, improving the versatility and applicability of the charging device. The first protective cover 41 is used to cover the USB Type-A interface 43, and the second protective cover 42 is used to cover the USB Type-C interface 44. When the charging interface is not in use, the protective cover can effectively prevent dust, moisture, foreign objects, etc. from entering the interface, avoiding problems such as poor contact or short circuits caused by contamination, and extending the service life of the interface. Meanwhile, the design of the protective cover also makes the charging output component 40 more aesthetically pleasing and neat, improving the overall quality of the product.
[0038] like Figure 4 As shown, a second flexible connecting strip 46 is hinged to one side of the USB Type-A interface 43, and the second flexible connecting strip 46 is connected to the first protective cover 41. Specifically, the function of the second flexible connecting strip 46 is similar to that of the first flexible connecting strip 54. When the first protective cover 41 is opened to use the USB Type-A interface 43, the flexible connecting strip can keep the protective cover connected to the USB Type-A interface 43, preventing the protective cover from being lost. The hinged design of the flexible connecting strip makes the opening and closing of the protective cover more convenient and flexible. Users do not need to worry about the storage of the protective cover when using the charging interface, improving the convenience of use.
[0039] like Figure 4 As shown, a third flexible connecting strip 47 is hinged to one side of the USB Type-C interface 44, and the third flexible connecting strip 47 is connected to the second protective cover 42. Specifically, similar to the second flexible connecting strip 46, the third flexible connecting strip 47 ensures that the protective cover remains connected to the interface when the second protective cover 42 is opened to use the USB Type-C interface 44, preventing the protective cover from being lost and facilitating user operation. The flexibility and hinged design of the flexible connecting strip allow the protective cover to open and close easily, while ensuring that the protective cover can be tightly closed on the interface when not in use, providing good protection.
[0040] The working principle of this utility model is as follows:
[0041] like Figure 5The diagram shows the circuit schematic of this invention. First, the positive terminal 21 and negative terminal 22 of the connecting component 20 are clamped to the positive and negative terminals of the vehicle battery by metal clips 24, respectively, to achieve electrical connection with the vehicle battery. The ACC switch terminal 23 is connected to the vehicle fuse box, forming a complete power input circuit. The electrical energy output from the vehicle battery is input to the charging control module 30 through the connecting component 20. The charging control module 30 converts and regulates the input electrical energy, adjusting it to a stable voltage suitable for charging mobile devices. Simultaneously, it monitors parameters such as current and voltage in real time during charging, performing safety adjustments to prevent overcharging, overcurrent, and other abnormalities. The processed electrical energy is transmitted to the USB Type-A interface 43 and USB Type-C interface 44 of the charging output component 40 through the branched wire 45. When charging a mobile device is required, the corresponding first protective cover 41 or second protective cover 42 is opened, and the charging cable of the mobile device is connected to the corresponding interface to charge the mobile device. When the charging port is not in use, the protective cover effectively protects the port from dust, moisture, and other contaminants. In the event of an overload or short circuit, the fuse 53 in the fuse assembly 50 will blow, cutting off the circuit and providing protection. Users only need to replace fuse 53 to restore the device to normal operation. The entire process ensures safe and stable power transfer from the vehicle battery to the mobile device, meeting the user's need to charge the mobile device while riding.
[0042] This utility model features a reasonable structure and complete functions, providing users with a safe, convenient, and efficient mobile device charging solution. In terms of safety, the design, including the ACC switch wiring 23 connecting to the vehicle fuse box, the positive wiring 21 connecting to the fuse assembly 50 in series, and the insulating protective sleeve 25 covering the wiring, effectively prevents circuit overload and short circuits, protecting the charging device and the vehicle battery. The design of the fuse cover 52 and the flexible connecting strip protects the fuse 53 and the charging interface, and prevents the cover from being lost, further enhancing safety. Regarding convenience, the metal clip 24 makes connecting the charging device to the vehicle battery easier and faster, requiring no complicated tools. The removable fuse 53 and the flexible connecting strip cover facilitate user maintenance and operation. In terms of applicability, the USB Type-A interface 43 and USB Type-C interface 44 meet the charging needs of mainstream mobile devices on the market, improving the device's versatility. The decorative surface 31 features a brand logo, enhancing the product's aesthetics and brand recognition.
[0043] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent.
