Description

Technical Field

[0001] This invention relates to a novel charging bag and charging connection device, particularly backpacks, handbags, suitcases, etc. with charging functions, for data and charging interfaces set on the bag to facilitate data transmission or power connection of electronic devices such as mobile phones, headphones, and power banks. Background Technology

[0002] Currently, charging ports are essential equipment on bags. Existing charging connectors fall into two main categories: raised and flat. Flat connectors offer the advantage of an aesthetically pleasing and high-end appearance, but are more expensive because the charging device and extension cable are integrated, requiring non-standard customization and lacking economies of scale to reduce costs. Raised connectors, on the other hand, are less aesthetically pleasing but cheaper because the extension cable and connector are separate components. These components belong to different industries; the connector is made of injection-molded plastic, while the extension cable is made of electronic wires. It's generally difficult for factories to produce these components across industries, requiring separate manufacturing and manual assembly. The efficiency is low, and the modular design makes it easy to process and assemble. The modular connecting device uses soft plastic for fixing by sewing, or hard plastic for fixing by U-shaped grooves. The disadvantage of fixing with hard plastic by U-shaped grooves is that it is easy to slip off. Therefore, sewing is still the mainstream product and accounts for the majority of the market share. When fixing to bags by sewing, the outer fabric and the lining fabric must be sewn separately, which results in a high proportion of labor costs. The efficiency is high and the cost is low. There is still room for further cost reduction. For example, using modular hard plastic injection molding and quick snap-on installation can further reduce costs. Therefore, there is currently no product on the market that can solve all the above-mentioned disadvantages and take into account the advantages. Summary of the Invention

[0003] To address the shortcomings of the aforementioned charging cases and charging connection devices, the present invention aims to provide a novel charging case and charging connection device that employs a split charging extension cable, combined with a new connection device, eliminates the sewing process, improves the U-shaped groove method, further reduces costs, and increases efficiency. To solve the above problems, the present invention adopts the following technical solution.

[0004] A novel charging case includes a case body and a charging connection device. The charging connection device includes a bottom shell, a top cover, and a charging extension cable. The bottom shell is disposed inside the case, and part of the top cover is disposed outside the case and part is disposed inside the case. The top cover has a receiving compartment and a charging output port. The charging extension cable includes an output end and an input end. The output end is installed in the receiving compartment. The top cover is provided with a limiting buckle or a limiting hole, the bottom shell is provided with a pressing spring, or the output end is provided with a limiting groove or a limiting protrusion, or a combination of one or more of these features.

[0005] A charging connection device includes a bottom shell, a top cover shell, and a charging extension cable. The top cover shell is provided with a receiving compartment. The charging extension cable includes an output end and an input end. The output end is installed in the receiving compartment. The top cover shell is provided with a charging output port. The top cover shell is provided with a limiting buckle or a limiting hole, the bottom shell is provided with a pressing spring, or the output end is provided with a limiting groove or a limiting protrusion, or a combination of one or more of these features.

[0006] The cover shell has an inclined surface.

[0007] The cover shell is provided with a limit strip.

[0008] Preferably, a limiting buckle is provided on the face cover near the charging output port.

[0009] Preferably, the output end is provided with a limiting protrusion and a limiting buckle and a limiting hole on the mating surface of the cover.

[0010] The technical solution of the present invention is as follows: a cover shell is used to set up a receiving compartment, the output end of the charging extension cable is installed in the receiving compartment, and the output end of the charging extension cable is clamped by a limiting buckle or limiting hole on the cover shell or a clamping spring on the bottom shell, thereby fixing the charging extension cable on the bag.

[0011] The beneficial effects of this invention are: because the charging extension cable and the connecting device are set separately, they are easy to process and assemble, improving production efficiency; because the top cover and bottom cover are connected by snap-fit, the stitching process is eliminated and the overall production efficiency is improved and the cost is reduced.

Detailed Implementation

[0036] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These exemplary embodiments are provided so that those skilled in the art can clearly understand the present invention and implement it based on the description herein. The drawings and specific embodiments are not intended to limit the scope of the invention, which is defined by the appended claims.

[0037] The above figures show an example of an outward-convex design. The specific implementation methods described below include both outward-convex and flat designs. The implementation methods are the same, the only difference being the appearance.

[0038] like Figure 1 , 2 As shown in Figures 4 and 13, in order to solve the problem of quickly fixing the charging extension cable to the bag, a new type of charging bag is provided, which includes the bag body and the charging connection device. The charging connection device includes a bottom shell (6), a top cover shell (9), and a charging extension cable (5). The bottom shell is located inside the bag, and part of the top cover shell is located outside the bag and part of the top cover shell is located inside the bag. The top cover shell is provided with a receiving compartment (2). The charging extension cable includes an output end and an input end. The output end is installed in the receiving compartment (2). The top cover shell is provided with a limiting buckle (8) or a limiting hole (15), or the bottom shell is provided with a pressing spring (12).

[0039] The charging connection device is usually installed on the side, front or top of the bag. When installing, first make a hole in the corresponding position of the bag, pass the cover through the hole, then place the charging output end of the charging extension cable inside the cover, and then close the bottom cover and press it to fix it.

[0040] like Figure 2 , 4 As shown in Figure 13, a charging connection device includes a bottom shell (6), a top cover shell (9), and a charging extension cable (5). The top cover shell is provided with a receiving compartment (2). The charging extension cable includes an output end and an input end. The output end is installed in the receiving compartment (2). The top cover shell is provided with a limiting buckle (8) or a limiting hole (15), or the bottom shell is provided with a pressing spring (12).

[0041] The charging extension cable is an existing product, consisting of an output end and an input end. The input end is generally a USB or Type-C plug, and the output end is generally a USB or Type-C female connector.

[0042] When the charging connection device has a limiting buckle inside the cover shell, simply place the output end of the charging extension cable inside the cover shell and press it down completely. The limiting buckle will then lock and fix the output end. The limiting buckle and the limiting hole can be replaced, but the principle is the same. It is preferable to use a pressing spring or a pressing spring plus a limiting buckle. When using a pressing spring alone, it is only necessary to set a pressing spring on the bottom shell. The pressing spring and the bottom shell are integrally formed. The pressing spring is set to be slightly longer. The pressing spring generates a pre-tightening force on the output end, which can be suitable for bags with different thicknesses of bag fabric or bags with intermediate layers, and can press and fix the charging output end.

[0043] The front cover is provided with a limiting buckle (8) or a limiting hole (15), or the bottom cover is provided with a pressing spring (12). These are parallel statements, and one or more combinations of them can be selected individually.

[0044] like Figure 2 , 13 As shown, the cover shell is provided with an inclined surface (13). If an outwardly protruding connecting device is used, since the charging output end of the charging extension line is in a straight line with the connecting line, in order to place the charging output end outside the bag and the connecting line inside the bag, the inclined arrangement is the only feasible solution.

[0045] like Figure 9 As shown, the faceplate is provided with a boss (16). In order to make the charging output end more firmly connected to the faceplate, the boss is provided on the faceplate and combined with the existing groove of the charging output end, so that the charging output end will not slide when the USB charging head is plugged in or unplugged.

[0046] like Figure 13 , 14 As shown, the face cover shell is provided with a limiting strip (14), which serves to guide the installation of the charging output terminal and limit the extension length of the charging output terminal or its installation position.

[0047] like Figure 2 , 13 As shown, in order to quickly fix the charging extension cable to the bag, the front cover (9) and the bottom cover (6) are connected by screws or buckles, with buckle connection preferred, and multi-level buckle connection can be used in the prior art.

[0048] like Figure 15As shown, the output end of the charging extension cable is provided with a limiting groove (17) or a limiting protrusion (18). The limiting groove (17) and the limiting protrusion (18) can be replaced, and their principles are the same. The limiting groove corresponds to the limiting buckle, and the limiting hole corresponds to the limiting protrusion. Alternatively, only the limiting buckle can be used, and the output end of the charging extension cable does not need to be provided with a limiting groove (17) or a limiting protrusion (18). The position of the limiting buckle or the limiting hole can be appropriately set on the four surfaces inside the receiving compartment (2).

[0049] like Figure 16 , 17 As shown, this is a preferred solution for a convex faceplate. A limiting buckle (8) is set at the charging output port of the faceplate (9). The charging extension line (5) can be clamped by the limiting buckle (8). This setting is very easy to implement, making the mold structure for product production simpler and more efficient.

[0050] like Figure 18 , 19 As shown in Figures 20, 21, and 22, this is a preferred embodiment of a flat faceplate. The output end is provided with a limiting protrusion (18) to complement the faceplate, which features both a limiting buckle (8) and a limiting hole (15). A limiting protrusion (18) is also provided on the charging extension cable (5). Figure 22 As shown, the limiting protrusion (18) is inserted into the limiting hole (15) and the limiting buckle (8) is pressed against the limiting protrusion (18). The limiting buckle (8) is elastic. When the limiting protrusion (18) is inserted, the limiting buckle (8) can elastically deform outward. When the limiting protrusion (18) is fully inserted, the limiting buckle (8) resets under the elastic action, so that the charging extension cable (5) can be firmly locked on the face cover (9).

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
