Description

Technical Field

[0001] This utility model relates to the field of bag accessories, specifically a modular USB base. Background Technology

[0002] In smart bag design, integrating USB charging functionality has become an important requirement for enhancing user experience. Traditional solutions typically embed the USB module within the bag's internal structure, securing the internal circuitry and interface with stitching. However, exposed stitching makes it difficult to balance aesthetics and protection, and concealing the stitching is challenging, forcing the USB module to be exposed on the bag's surface as an external component.

[0003] Traditional embedded USB docks require sewing to secure them to textiles (such as bags, car seat covers, and home textiles). Exposed seams on the dock surface can lead to several aesthetic issues, including poor appearance: the exposed seams negatively impact the overall aesthetics of the product.

[0004] Easy to accumulate dust and wear: Dirt easily accumulates in the seam grooves and is prone to breakage due to long-term friction; Uneven installation: Uneven seam tension causes the base to not fit tightly with the fabric.

[0005] Existing improvement solutions mostly involve adding a cover to the edge of the base, but these solutions have drawbacks such as large size of the cover, slippage, and inability to completely cover the stitching. Utility Model Content

[0006] To overcome the problems existing in related technologies, this application provides a modular USB base that, through an axially sliding hidden frame structure, completely covers the seam between the base and the fabric after sewing, achieving an "invisible" installation effect. It hides the sewing lines, is compatible with different fabrics, is easy to assemble and disassemble, has a simple structure, and is highly practical.

[0007] This application provides a combined USB base, including a base and a protruding seat. The base has a hollow portion at its bottom, and the protruding seat extends vertically from the hollow portion, with a USB plug-in opening at its top. It also includes a hidden frame. The hidden frame is a hollow square annular structure, fitted over the protruding seat and axially sliding. An annular limiting flange restricts the upward movement of the hidden frame on its outer side. The limiting flange completely solves the problem of sliding components coming loose, and the sliding structure of the hidden frame effectively conceals the stitching.

[0008] Preferably, the projected area of ​​the hidden frame is smaller than that of the base, and the hidden frame can completely cover the upper surface of the base. Improved aesthetics: The hidden frame covers the base and hides the stitching, resulting in a neat appearance.

[0009] Preferably, the outer wall of the hidden frame is an inclined step that gradually expands from top to bottom, and the inner wall of the hidden frame is an internal through-hole that can hide the stitching.

[0010] Preferably, the hidden frame is provided with a recessed entrance corresponding to the USB plug-in opening and rounded outer contour corners.

[0011] Preferably, the top of the protruding seat has a trapezoidal guide opening. Insertion / removal protection: The recessed inlet and trapezoidal guide opening reduce the interface damage rate.

[0012] Preferably, the trapezoidal guide opening extends axially along the protruding seat, with the long side of its trapezoidal cross-section facing the USB plug-in opening. Anti-collision design: a ramp surface prevents hard impacts from USB devices.

[0013] Preferably, the back USB plug-in opening at the top of the protruding seat 2 is provided with a ramp surface that slopes toward the center of the opening.

[0014] Preferably, the contact surfaces of the base and the protruding seat are provided with inclined stripes, and the edges of the base and the protruding seat are provided with anti-slip protrusions. High stability: The anti-slip stripes and protrusions enhance the base's resistance to displacement.

[0015] Preferably, it also includes a pressure-fitting buckle for pressing down on the mold to hold the hidden frame, the pressure-fitting buckle being a frame-shaped structure with a central hollow. The pressure-fitting buckle (13) simplifies the mold-making process and reduces costs.

[0016] Preferably, the maximum sliding distance between the hidden frame and the base is 2-5mm. It is compatible with fabrics of various thicknesses and is highly practical.

[0017] The working principle and beneficial effects of this application are as follows:

[0018] 1. Concealment: The hidden frame 100% covers the seam area, and there are no visible seams on the surface;

[0019] 2. Process compatibility: The hidden frame is movable to adapt to fabrics of different thicknesses;

[0020] 3. Durability: The structure is simple and durable, and the flange limit prevents it from falling off due to impact;

[0021] 4. Human-computer interaction: The slope surface and guide port reduce the insertion rate by more than 60%, and the anti-slip design improves stability.

[0035] To address the aforementioned issues, this application provides a modular USB dock that conceals stitching, is compatible with various fabrics, is easy to assemble and disassemble, has a simple structure, and is highly practical.

[0036] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0037] Referring to Figures 1 to 7, a combined USB base includes a base 1 and a protruding seat 2; the base 1 has a hollow portion 3 at its bottom, and the protruding seat 2 extends vertically from the hollow portion 3, with a USB plug-in opening 4 at its top; it also includes a hidden frame 5; the hidden frame 5 is a hollow square ring structure that is fitted outside the protruding seat 2 and can slide axially; the outer side of the protruding seat 2 is provided with an annular limiting flange 6 to restrict the upward movement of the hidden frame 5.

[0038] In this embodiment, the hidden frame 5 slides axially along the protruding seat 2. During sewing, the hidden frame is first pushed up until the limiting flange 6 exposes the edge of the base 1 for the sewing thread to be fixed; after installation, the hidden frame is pressed down to completely cover the upper surface of the base 1. Figure 4 The sliding design separates the sewing operation from the concealing function, completely hiding the seams.

[0039] In other embodiments, the projected area of ​​the hidden frame 5 is smaller than that of the base, and the hidden frame 5 can completely cover the upper surface of the base 1.

[0040] In this embodiment, the projected area of ​​the hidden frame 5 is smaller than that of the base 1, and it completely covers the upper surface of the base after sliding. This eliminates visible seam marks and improves aesthetics.

[0041] In other embodiments, the outer sidewall 7 of the hidden frame 5 is an inclined step that gradually expands from top to bottom, and the inner sidewall 8 of the hidden frame 5 is an internal through-hole that can hide the stitching.

[0042] In this embodiment, the outer sidewall 7 is an inclined step that gradually widens from top to bottom, and the lower edge of the step is pressed against the fabric after sewing; the inner sidewall 8 is a through-type hollow structure that forms a seamless overlap with the base 1 when covering the protruding seat 2. The inclined step presses the edge of the fabric, and the hollow structure avoids obstructing the USB opening while also concealing the stitching of the base.

[0043] In other embodiments, the hidden frame 5 is provided with a recessed entrance 9 corresponding to the USB plug-in opening and an outer contour corner 10 with a rounded transition.

[0044] In this embodiment, the hidden frame 5 has a recessed inlet 9 to guide the USB plug, and the outer contour corners 10 are rounded. This prevents the plug from scratching the fabric during insertion and removal, and improves the smoothness of operation.

[0045] In some other embodiments, the top of the protruding seat 2 is provided with a trapezoidal guide opening 11.

[0046] In other embodiments, the trapezoidal guide extends axially along the protrusion 2, with the long side of its trapezoidal cross-section facing the USB plug-in opening 4.

[0047] In other embodiments, the top of the protruding seat 2 has a slope surface 12 that slopes towards the center of the USB plug-in opening 4.

[0048] In this embodiment, the top of the protruding seat 2 has a trapezoidal guide opening 11, with its long side facing the USB opening; a ramp surface 12 is provided on the end facing away from the opening to guide the plug hole at an angle. The dual-guide structure prevents the USB plug from shifting and reduces port wear.

[0049] In other embodiments, the contact surfaces of the base 1 and the protruding seat 2 are provided with inclined stripes, and the edges of the base 1 and the protruding seat 2 are provided with anti-slip protrusions.

[0050] In this embodiment, the base 1 has slanted stripes on the surface in contact with the fabric, and anti-slip raised dots are added to the edges. This enhances the stability of the base during sewing, prevents displacement, and prevents slippage during use.

[0051] In other embodiments, a pressure film buckle 13 for pressing down the mold to hold the hidden frame is also included, the pressure film buckle 13 being a frame shape with a central hollowed-out shape.

[0052] In other embodiments, the maximum sliding distance between the hidden frame 5 and the base 1 is 2-5 mm.

[0053] The pressure-fitting buckle 13 forms a central hollow frame, which is secured to the hidden frame 5 when the mold is pressed down; the sliding stroke of the hidden frame 5 is limited to 2–5mm. The 2–5mm sliding distance adapts to various fabric thicknesses, is compatible with various usage scenarios, and precisely controls the sliding distance to ensure that the seams are covered without obstructing the USB interface.

[0054] The specific implementation steps are as follows:

[0055] Step 1: Sew and secure: Slide the hidden frame 5 to expose the edge of the base 1; sew the base 1 to the fabric (such as leather) surface, with the seam located at the outer edge of the base 1;

[0056] Step 2: Conceal the seams: Press down the concealing frame 5 to completely cover the upper surface of the base 1, press the edge of the fabric with the inclined stepped outer wall 7, and seamlessly cover the protruding seat 2 at the hollowed-out part of the inner wall 8 to completely conceal the seams.

[0057] Step 3 is the USB plugging and unplugging operation: The USB plug is inserted through the recessed inlet 9 along the long side of the trapezoidal guide port 11, and the ramp surface 12 assists in correcting the offset plug.

[0058] The technical solution provided in this application has the following beneficial effects:

[0059] 1. Completely concealed stitching: The stitching is double-concealed through the sloping steps of the sliding concealed frame and the hollow structure;

[0060] 2. Compact and stable structure: The projected area of ​​the hidden frame is smaller than that of the base, and the flange limit prevents it from falling off due to impact;

[0061] 3. Extended service life: Anti-misalignment design reduces port wear, and anti-slip structure prevents sewing shift.

[0062] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
