Description

Technical Field

[0001] This utility model relates to the field of chargers, specifically to a data cable telescopic guide structure and a vehicle charger. Background Technology

[0002] With the widespread use of mobile electronic devices, car chargers have become an essential tool for charging mobile phones, tablets, and other devices in the in-vehicle environment, and are now widely used. To meet the charging needs of various devices, existing car chargers typically integrate multiple interfaces and are equipped with a retractable data cable winding mechanism for easy use and storage within the vehicle. However, existing car chargers often suffer from the following problems when using retractable data cables:

[0003] First, during the winding or pulling process, data cables are prone to friction with the inner wall of the housing or the winding mechanism components, leading to accelerated surface wear, shortened lifespan, and impacting the overall product reliability and aesthetics. This is especially true for flat data cables, whose wider cross-sections make them susceptible to folding, twisting, or jamming if there is a lack of effective guiding structures during the process, further increasing resistance and the risk of wear.

[0004] Secondly, some existing technologies attempt to alleviate the above problems by adding simple guide elements to the data cable channel. However, these structures are complex, inconvenient to install and disassemble, and have high maintenance costs, which is not conducive to large-scale production and subsequent repairs. In addition, the way these guide elements are fixed to the housing or motherboard is relatively simple, which often leads to insufficient structural stability. After long-term use, they are prone to loosening or shifting, affecting the normal extension and retraction function of the data cable. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a data cable telescopic guide structure and a vehicle charger. The data cable telescopic guide structure for the vehicle charger is simple in structure, easy to install and disassemble, and can effectively guide the extension and retraction of the data cable, reducing frictional losses.

[0006] This utility model is achieved through the following technical solution: a data cable telescopic guide structure, including a housing, at least one telescopic winding mechanism is installed inside the housing, and at least one interface storage slot is provided outside the housing. Each telescopic winding mechanism is provided with one interface storage slot. A guide is installed on the housing inside each interface storage slot. The data cable wound on the telescopic winding mechanism passes through the guide and extends to the outside of the housing and is located in the interface storage slot.

[0007] As a preferred technical solution, the guide includes a first mounting component, a second mounting component, and at least two movable guide devices. The first mounting component and the second mounting component are assembled together, and at least two movable guide devices are installed between the first mounting component and the second mounting component. A wire guide cavity is formed between the at least two movable guide devices, and the flat data cable passes through the wire guide cavity and extends to the outside of the housing.

[0008] As a preferred technical solution, the first mounting component and the second mounting component are positioned and assembled by positioning pins.

[0009] This utility model discloses a vehicle charger, including a housing and guide members. A cigarette lighter plug is rotatably mounted on one side of the housing, and the cigarette lighter plug is provided with conductive contacts. A charging main board is installed inside the housing, and the guide members are all fixedly mounted on the charging main board. A through wire groove is provided on the charging main board at the position corresponding to the guide member.

[0010] As a preferred technical solution, the cigarette lighter plug is rotatably connected to the housing, and rotatable connecting parts are provided on both sides of the cigarette lighter plug. The cigarette lighter plug is rotatably connected to the rotatable connecting ears on the housing through the rotatable connecting parts.

[0011] As a preferred technical solution, the housing includes a front shell and a bottom shell, which are assembled together. It also includes an end cap, which is assembled together with the front shell and the bottom shell. The interface storage slot is integrated on the end cap.

[0012] As a preferred technical solution, a decorative cover is fitted onto the outside of the housing.

[0013] The beneficial effects of this utility model are as follows: By setting a guide component inside the vehicle charger, and the guide component including a first mounting component, a second mounting component, and at least two movable guide devices, a wire guide cavity is formed for guiding the flat data cable. This allows the data cable to move smoothly along a set path during the extension and retraction process, avoiding direct friction contact between the data cable and the housing or other components, effectively reducing wear caused by repeated pulling and extending of the data cable, and improving the service life of the data cable. At the same time, the guide component is positioned and assembled using positioning posts, which facilitates quick installation and disassembly, reduces assembly difficulty and maintenance costs, and improves product production efficiency and maintenance convenience.

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figures 1-2 As shown, this utility model provides a data cable telescopic guide structure, including a housing 3. At least one telescopic winding mechanism 9 is installed inside the housing 3 to realize the retraction and release of the data cable. At least one interface storage slot 5 is provided on the outside of the housing 3, with each telescopic winding mechanism 9 corresponding to one interface storage slot 5, facilitating the neat storage of the data cable end within the slot. A guide member 7 is installed on the housing 3 inside each interface storage slot 5. The data cable wound on the telescopic winding mechanism 9 passes through the guide member 7 and extends to the outside of the housing 3, residing within the interface storage slot 5. This achieves orderly guidance and storage of the data cable, preventing direct friction between the data cable and the housing 3 or other components during winding and pulling, thus reducing wear.

[0023] In this embodiment, as Figure 3 As shown, the guide component 7 includes a first mounting component 71, a second mounting component 72, and at least two movable guide devices 73. The first mounting component 71 and the second mounting component 72 are assembled together, and the at least two movable guide devices 73 are fixedly installed between the first mounting component 71 and the second mounting component 72, forming a wire guide cavity between the at least two movable guide devices 73. This wire guide cavity is used to regulate and guide the extension path of the data cable, and is particularly suitable for guiding flat data cables. The flat data cable passes through the wire guide cavity and then extends to the outside of the housing 3, effectively avoiding problems such as kinking, jamming, or abnormal wear of the data cable during use.

[0024] To facilitate the assembly and disassembly of the guide component 7 and further improve production efficiency and ease of maintenance, preferably, the first mounting component 71 and the second mounting component 72 are positioned and assembled by positioning pins to ensure stable installation and accurate positioning of each component of the guide component 7, reduce assembly errors, and improve product consistency and reliability.

[0025] This utility model also relates to a vehicle charger, which includes a housing 3 and the aforementioned guide members 7. A cigarette lighter plug 2 is rotatably mounted on one side of the housing 3. The cigarette lighter plug 2 is connected to the vehicle power supply through conductive contacts 1 provided thereon to realize the power supply function. A charging motherboard 6 is installed inside the housing 3 for controlling and managing the charging function. The guide members 7 are all fixedly mounted on the charging motherboard 6. Corresponding to the positions of the guide members 7, the charging motherboard 6 is provided with through-hole wire grooves, which allow the data cable to be smoothly guided through the guide members 7 and wire grooves, improving the overall storage effect and smoothness of the data cable extension.

[0026] To ensure a reliable rotating connection of the cigarette lighter plug 2 during use, the cigarette lighter plug 2 and the housing 3 are connected by a rotating connection part 8. The cigarette lighter plug 2 is provided with rotating connection parts 8 on both sides, and the rotating connection parts 8 are connected to the rotating connection ears 10 on the housing 3. This ensures that the cigarette lighter plug 2 can rotate relative to the housing 3 within a certain angle range, improving the convenience and adaptability of plugging and unplugging.

[0027] To facilitate assembly and maintenance of the overall structure, the housing 3 includes a front shell 31 and a bottom shell 32, which are assembled together to form an internal installation space. It also includes an end cap 4, which is assembled with the front shell 31 and the bottom shell 32. An interface storage slot 5 is integrated into the end cap 4, making the overall structure more compact and improving the space utilization and overall aesthetics of the vehicle charger. Furthermore, a decorative cover 33 is fitted onto the exterior of the housing 3. The decorative cover 33 not only enhances the aesthetics but also provides some protection to the housing 3, improving the overall texture and durability of the product.

[0028] This utility model optimizes the data cable winding process by rationally setting the telescopic winding mechanism 9, guide component 7, charging motherboard 6 and various connecting structures, thereby improving the durability and ease of use of the vehicle charger's data cable. It also ensures the stability and aesthetics of the assembly structure, and has good practical value and market application prospects.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
