[0003] Currently, computer bags on the market are primarily used to store laptops. Some bags feature internal compartments to facilitate the centralized storage of laptop peripherals, such as chargers and cables. To meet user needs, existing computer bags also require compartments to accommodate a variety of other electronic products, such as mobile phones, headphones, and smart wearable devices, allowing for categorized placement within the bag. However, current computer bags offer a limited functionality, serving only as a storage device and failing to meet the demands of today's users. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a computer bag to solve the technical problem of the single function of the computer bag in the prior art.

[0005] To achieve the above-mentioned purpose, the technical solution adopted in this application is to provide a computer bag, comprising a loading part and a folding part connected in one piece,

[0006] The loading portion has an opening for loading a laptop computer, and the folding portion can be folded on at least a portion of the loading portion to close the opening;

[0007] A charging module is provided on the folding part, and the charging module includes a first wireless charging module for charging a smartphone, a second wireless charging module for charging a wireless headset, and a third wireless charging module for charging a smart wearable device; when the folding part is in the unfolded state, the electrical contact ends on the first wireless charging module, the second wireless charging module and the third wireless charging module are all exposed.

[0008] The beneficial effect of the computer bag provided by the present application is that: compared with the prior art, the computer bag of the present application adopts a handbag design, and the computer bag includes a loading part and a folding part that are integrally connected. An opening is provided at one end of the loading part close to the folding part, so that a laptop computer such as a MACBOOK can be loaded into the loading part through the opening; then, the folding part is folded onto the loading part to close the opening on the loading part, making it convenient to store the laptop computer.

[0009] The foldable portion of the laptop bag houses a charging module, which includes a first wireless charging module for charging smartphones, a second wireless charging module for charging wireless headphones, and a third wireless charging module for charging smart wearable devices.

[0012] The structure of the first hinge mechanism has been improved. The first hinge mechanism includes a pair of hinges and a first rotating shaft. The hinges are respectively provided on the first wireless charging module and the upper housing. The hinges are each provided with a curled edge for sleeved onto the first rotating shaft. Top caps are provided at each end of the first rotating shaft. The top caps at each end press against the curled edges of the hinges to generate a damping force. This helps to stabilize the opening angle of the folding plate and improves the securing effect of the folding plate after it is opened.

[0013] The structure of the second hinge mechanism is improved. The second hinge mechanism includes a connecting frame extending from the third wireless charging module and a connecting plate arranged on the main control board. A second rotating shaft is provided on the connecting end of the connecting frame, and a reel for being sleeved on the second rotating shaft is provided on the connecting plate. The inner wall of the reel and the outer periphery of the second rotating shaft are provided with mutually matching positioning surfaces, thereby fixing the relative rotation angle between the connecting frame and the connecting plate, thereby improving the fixing effect of the third wireless charging module after it is erected.

[0014] In one embodiment, the charging module is mounted on the folding portion. The folding portion is provided with a frame for mounting the box body. The box body is embedded in the frame, and the outer periphery of the box body is fixedly connected to the folding portion surrounding the outer periphery of the frame. In this way, the folding portion can be folded toward the loading portion, with the side of the box body closest to the loading portion opening serving as the folding edge.

[0015] In another embodiment, the charging module is mounted on the folding portion. The folding portion comprises an upper and lower outer cover that can be joined together. Both the upper and lower covers are provided with protrusions that match the shape of the case. The protrusions on the upper and lower covers join together to form a cavity for accommodating the case. In this way, the case is wrapped between the upper and lower covers of the folding portion, resulting in a leather-like surface throughout the folding portion, giving the laptop bag a unified overall texture and enhancing its aesthetics.

[0016] In one embodiment, the upper and lower outer shells are each provided with a second through-hole corresponding to the first through-hole on the housing, and the third wireless charging module is disposed within the space where the first and second through-holes overlap. This creates a through-space formed by the overlapping first and second through-holes on the foldable portion, with the third wireless charging module disposed within the through-space, facilitating erection and repositioning operations.

[0017] In one embodiment, the main control board is further provided with a power connection terminal, and the box body is provided with a socket connected to the outside, and the power connection terminal is exposed in the socket, which is convenient for connecting to an external power source through a cable.

[0018] In one embodiment, both the loading portion and the folding portion are made of a flexible material. This allows the loading portion to adapt to the shape or volume of the laptop computer housed therein, thereby improving adaptability. The folding portion can also be smoothly folded or unfolded onto the loading portion, providing flexible operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0048] Traditional computer bags primarily store laptops, and some feature internal compartments to facilitate the centralized storage of laptop peripherals, such as chargers and cables. To meet user needs, existing computer bags also require compartments to accommodate a variety of other electronic products, such as mobile phones, headphones, and smart wearable devices, allowing them to be organized and arranged within the bag. However, current computer bags offer a limited functionality, serving only as a storage device and failing to meet the demands of today's users.

[0049] In the related art, there is a structure in which a power bank is placed inside a laptop bag, and the data cable of the power bank is then used through a splitter to simultaneously charge multiple electronic products, thereby forming a charging station for the laptop bag and adding charging functionality to the laptop bag. However, this laptop bag with charging function is very simple, relying on the power bank installed inside for charging, and requires a data cable for wired connection, thus failing to truly add charging functionality to the laptop bag.

[0050] Therefore, the present invention provides a laptop bag with wireless charging functionality. This redesigned structure incorporates a wireless charging module capable of charging electronic products. This eliminates the interference and storage issues caused by wired cables, resulting in a significantly simpler overall structure. This ensures effective storage for laptops while also providing the ability to charge electronic products. When opened, the bag becomes a work platform, facilitating user use for work, entertainment, and other scenarios. This effectively addresses the limited functionality of traditional laptop bags. This is now described in detail.

[0051] Please also refer to Figure 1 、 Figure 2 and Figure 3 The computer bag adopts a simple flat handbag structure, and the computer bag includes an integrally connected loading part 1 and a folding part 2. The loading part 1 and the folding part 2 can preferably be made of a flexible material, such as leather, canvas and other materials. Specifically, they can be preferably made of polyurethane synthetic leather material. Polyurethane synthetic leather belongs to a type of polyurethane elastomer, has a soft and natural gloss, soft hand feel, and a strong leather feel. It has excellent mechanical properties such as excellent adhesion to the substrate, wear resistance, flex resistance, and aging resistance. At the same time, it also has the advantages of good cold resistance, breathability, washability, and easy processing. It is the most ideal substitute for natural leather.

[0052] The loading portion 1 has an opening 11, preferably located near the folding portion 2, so that a laptop computer can be loaded into the loading portion 1 through the opening 11. The folding portion 2 serves as a sealing strip and can be folded over at least a portion of the loading portion 1. The specific size of the folding portion 2 can be determined by the volume of the folding portion 2 and is not specifically limited herein, so that the folding portion 2 can close the opening 11.

[0053] Please also refer to Figure 1 and Figure 3 The folding portion 2 is provided with a charging module 100, which includes at least a first wireless charging module 3, a second wireless charging module 4, and a third wireless charging module 5. The first wireless charging module 3 is used to charge smartphones, the second wireless charging module 4 is used to charge wireless headphones, and the third wireless charging module 5 is used to charge smart wearable devices such as smart watches.

[0054] When the folding portion 2 is in the unfolded state, such as when the folding portion 2 is unfolded, the inner side surface of the folding portion 2 is exposed, so that the electrical contact ends on the first wireless charging module 3, the electrical contact ends on the second wireless charging module 4, and the electrical contact ends on the third wireless charging module 5 provided on the folding portion 2 are all exposed, allowing users to place corresponding electronic products on the corresponding charging modules for charging according to usage needs.

[0055] Preferably, the above-mentioned multiple wireless charging modules can be arranged in an orderly manner on the surface of the charging module 100 according to the surface area of ​​the charging module 100, so that the user can place corresponding electronic products on each wireless charging module for simultaneous charging.

[0056] Compared to the prior art, the computer bag provided in the embodiment of the present application has a significantly simpler overall structure. The computer bag adopts a handbag design, resembling a flat bag. The computer bag comprises an integrally connected loading portion 1 and a folding portion 2. The loading portion 1 has an opening 11 at one end near the folding portion 2, allowing a laptop computer, such as a MacBook, to be loaded into the loading portion 1 through the opening 11. The folding portion 2 is then folded onto the loading portion 1, thereby closing the opening 11 in the loading portion 1 and conveniently storing the laptop computer.

[0057] The laptop bag of this application is equipped with a charging module 100 on the folding portion 2. The charging module 100 includes a first wireless charging module 3 for charging a smartphone, a second wireless charging module 4 for charging wireless headphones, and a third wireless charging module 5 for charging smart wearable devices. When the folding portion 2 is unfolded, it forms a wireless charging platform for charging smartphones, wireless headphones, and smart wearable devices such as smart watches. These three electronic products can be placed on the charging module 100 for wireless charging at the same time, effectively increasing the functionality of the laptop bag.

[0058] Compared with the computer bag structure with a built-in wired power bank in the above-mentioned related art, the computer bag of the embodiment of the present application adopts a wireless charging design, which is conducive to eliminating the interference and storage problems caused by wired cables, making the structure of the entire computer bag more concise and convenient to use.

[0059] Preferably, the first wireless charging module 3, the second wireless charging module 4 and the third wireless charging module 5 on the charging module 100 all have a magnetic function. Specifically, a magnetic component (not shown) can be added to the electrical contact end of each charging module to enable electronic products to be magnetically fixed to the corresponding charging module, realize automatic electrical connection and alignment, and be firmly fixed on the charging module, effectively improving the stability of the charging connection.

[0060] As an example, in one usage scenario, see Figure 4 The foldable part 2 can be unfolded to form a separate charging platform, and electronic products can be placed on the corresponding charging module for charging according to needs. The laptop can be placed in the area outside the computer bag for use.

[0061] In another usage scenario, see Figure 4After the folding part 2 is unfolded, the computer bag can be used as a work platform with charging function. The laptop computer can be placed on the area of ​​the loading part 1, and electronic products can also be placed on the folding part 2 for simultaneous charging, which effectively improves the applicability of the computer bag and is conducive to meeting the user's multi-scenario usage needs.

[0062] For the detailed structure of the charging module 100, please refer to Figure 4 、 Figure 5 and Figure 6 The charging module 100 further includes a box body 6 , a folding plate 7 and a main control board 8 disposed inside the box body 6 , and each charging module is electrically connected to the main control board 8 .

[0063] The first wireless charging module 3 is arranged on the folding plate 7, which is connected to the box body 6 via a first hinge mechanism 200. A smartphone can be placed on the folding plate 7, which is opened upward from the box body 6 to form a stand to stand the smartphone.

[0064] like Figure 6 As shown, the second wireless charging module 4 is disposed on the main control board 8, and the electrical contact end of the second wireless charging module 4 is disposed on the outer surface of the box body 6. The wireless earphones are loaded into the earphone box with wireless charging function, and the earphone box is placed on the electrical contact end of the second wireless charging module 4 to achieve charging connection.

[0065] The housing 6 defines a first through-hole 60 capable of accommodating the third wireless charging module 5. The third wireless charging module 5 is positioned within the first through-hole 60 and connected to the main control board 8 via a second hinge mechanism 300. The second hinge mechanism 300 allows the third wireless charging module 5 to move within the first through-hole 60. For example, when in use, the third wireless charging module 5 can be flipped upright to facilitate insertion into the ring of the smart wearable device and contact the charging contacts on the back of the smart wearable device to establish a charging connection. When not in use, the third wireless charging module 5 can be repositioned, restoring the surface of the foldable portion 2 to a flat surface.

[0066] In actual applications, in the computer bag of the embodiment of the present application, since the loading part 1 and the folding part 2 are both made of flexible materials, the electrical components on the charging module 100, such as the main control board 8, are easily damaged by external forces.

[0067] Here, in one embodiment of the present application, please refer to Figure 4 、 Figure 5 and Figure 6The housing 6 includes an upper shell 61 and a lower shell 62, which together form an inner cavity for accommodating the main control board 8. The main control board 8 can be accommodated within the housing 6, and the housing 6 can resist external forces affecting the main control board 8, thereby extending the service life of the charging module 100.

[0068] Among them, Figure 6 As shown, the upper shell 61, the lower shell 62 and the main control board 8 are all provided with corresponding first through holes 60, so that the third wireless charging module 5 can be set in the first through hole 60 and connected to the main control board 8 through the second hinge mechanism 300.

[0069] In this way, a through-hole structure that completely penetrates the box body 6 is formed on the box body 6. The third wireless charging module 5 is in this through-hole structure. The user can push the third wireless charging module 5 from one side of the box body 6 to rotate the third wireless charging module 5 with the second hinge mechanism 300 and stand upright from the other side of the box body 6 for easy use.

[0070] Regarding the hinge mechanism on the charging module 100, in one embodiment of the present application, please refer to Figure 7 、 Figure 8 and Figure 9 The first hinge mechanism 200 includes a pair of hinges 71 and a first rotating shaft 72 , one of the hinges 71 is arranged on the first wireless charging module 3 , and the other hinge 71 is arranged on the upper shell 61 of the box body 6 .

[0071] like Figure 8 and Figure 9 As shown, the pair of hinges 71 are each provided with a curling edge 711 for sleeved onto the first rotating shaft 72. Top caps 721 are provided at each end of the first rotating shaft 72. The top caps 721 at each end press against the curling edges 711 of the pair of hinges 71 from both sides to generate a damping force. This helps to stabilize the opening angle of the folding plate 7 and improves the fixing effect of the folding plate 7 after it is opened.

[0072] Preferably, the curled edges 711 on the pair of hinges 71 preferably constitute a cylindrical structure, so that the curled edges 711 can completely surround the outer periphery of the first rotating shaft 72, thereby increasing the contact area between the inner wall of the curled edges 711 and the outer periphery of the first rotating shaft 72, effectively increasing the friction force, and thereby improving the fixing effect of the folding plate 7 after it is erected.

[0073] For the specific structure of the second hinge mechanism 300, please refer to Figure 10 and Figure 11The second hinge mechanism 300 includes a connecting frame 51 and a connecting plate 52. The connecting frame 51 extends from the third wireless charging module 5. A second rotating shaft 511 is provided on the connecting end of the connecting frame 51. The connecting plate 52 is provided on the main control board 8 and is movably connected to the connecting frame 51 via the second rotating shaft 511.

[0074] like Figure 11 As shown, the connecting plate 52 is provided with a reel 521 for sleeved engagement with the second rotating shaft 511. The inner wall of the reel 521 and the outer periphery of the second rotating shaft 511 are provided with mutually mating positioning surfaces 53. In this embodiment, the positioning surfaces 53 are preferably provided on corresponding planes on the inner wall of the reel 521 and the outer periphery of the second rotating shaft 511, respectively, so that the rotation angle can be positioned when the two positioning surfaces 53 overlap.

[0075] In this way, the relative rotation angle between the connecting frame 51 and the connecting plate 52 is fixed, effectively improving the fixing effect of the third wireless charging module 5 after it is erected.

[0076] The specific form of the charging module 100 being arranged on the folding part 2 includes but is not limited to the following forms.

[0077] In one embodiment of the present application, see Figure 12 A frame opening (not shown) for arranging the box body 6 is opened on the folding part 2, and the box body 6 is embedded in the frame opening. The outer periphery of the box body 6 is fixedly connected to the folding part 2 surrounding the outer periphery of the frame opening. Specifically, ultrasonic welding can be preferably used to fix the box body 6 in the frame opening.

[0078] In this regard, please combine Figure 3 As shown, the folding portion 2 can be folded toward the loading portion 1 with the side of the box body 6 close to the opening 11 of the loading portion 1 as a folding edge, and close the opening 11 of the loading portion 1.

[0079] In another embodiment of the present application, see Figure 13 The folding portion 2 includes an upper outer skin 21 and a lower outer skin 22 that can be assembled with each other. It is also preferred that the folding portion 2 and the loading portion 1 are both formed by combining the upper and lower outer skins.

[0080] Both the upper outer skin 21 and the lower outer skin 22 are provided with protrusions 23 that match the shape of the box body 6, and the protrusions 23 on the upper outer skin 21 and the protrusions 23 on the lower outer skin 22 are assembled together to form a cavity for accommodating the box body 6.

[0081] In this way, the box body 6 is wrapped between the upper outer skin 21 and the lower outer skin 22 of the folding portion 2, making the entire surface of the folding portion 2 a leather structure, giving the laptop bag a unified overall texture, which is conducive to improving the aesthetics and making the laptop bag more fashionable. When in use, the folding portion 2 can be folded toward the loading portion 1 with the protrusion 23 closer to the opening 11 of the loading portion 1 as the folding edge, thereby closing the opening 11 of the loading portion 1.

[0082] Among them, Figure 13 As shown, the upper outer shell 21 and the lower outer shell 22 are both provided with a second through hole 24 corresponding to the position of the first through hole 60 on the box body 6, and the third wireless charging module 5 is arranged in the space where the first through hole 60 and the second through hole 24 overlap.

[0083] In this way, the folding portion 2 has a through space formed by the overlapping first through hole 60 and the second through hole 24, and the third wireless charging module 5 is arranged in the through space, which is conducive to the movable operation of standing up or resetting.

[0084] Regarding the structure on the box body 6, in one embodiment of the present application, please refer to Figure 6 and Figure 14 The main control board 8 is also provided with a power connection terminal 81, and the box body 6 is provided with a socket 63 connected to the outside.
