[0041] Example 1

[0042] Please see Figures 1-5 As shown, this invention provides a layered laptop briefcase with a wireless charging module, applicable to briefcases and laptop bags. The briefcase includes a pair of bag bodies 100 and a connecting strap 200 between their top edges. The bottom of the pair of bag bodies 100 can switch between an open and closed state. In the open state, a charging area 210 is formed between the pair of bag bodies 100, and a wireless charging module 230 is disposed within the charging area 210 for charging the laptop and maintaining airflow for timely heat dissipation during charging. A shelf 220 is glued or riveted below the connecting strap 200 for placing the laptop, and the wireless charging module 230 is embedded in the side wall of the shelf 220. Several ventilation windows 221 are provided on both sides of the shelf 220.

[0043] The wireless charging module 230 includes a main control PCB board, a transmitting coil, and a metal heat sink attached to the back of the PCB board. It is also equipped with an LED indicator to display the charging status and fault alarm. The wireless charging module 230 is equipped with a power cord for external power supply; or a battery pack can be configured on the shelf 220 for power supply. The above are existing technologies and will not be described in detail here.

[0044] Furthermore, a concealed connector is provided between the opposite sides of the pair of bag bodies 100, which can be closed by one of the following: zipper, Velcro, or snap fastener, so that it can be opened quickly and easily when the laptop needs to be charged.

[0045] Furthermore, a pair of unfolding racks are provided between the bottom side walls of the pair of bag bodies 100 to stabilize the space of the charging area 210; so that the pair of bag bodies 100 can be unfolded into a figure eight shape and stand stably, ensuring smooth heat dissipation of the charging area 210; or when carrying the briefcase, the unfolding racks can be used to open the pair of bag bodies 100 to keep the heat dissipation space open and to ensure stable heat dissipation.

[0046] Specifically, one form of the display rack is a support component 300, which consists of a pair of hinged frames 310, a pair of steering rods 320, and a pair of guides 330. The opposite ends of the pair of hinged frames 310 are hinged, and the other end of the hinged frame 310 is hinged to the steering rod 320. The hinges are interference fits, so that the pair of hinged frames 310 can be positioned and opened after they are unfolded.

[0047] To facilitate the folding of a pair of hinged frames 310 and the closing of a pair of packages 100, the guide 330 is a fan-shaped frame with a groove 331 at its arc edge. The groove 331 is arc-shaped and its central axis coincides with the central axis of the guide 330. The two ends of the steering rod 320 are provided with convex shafts 321 vertically. One convex shaft 321 is inserted into the central shaft hole of the guide 330 for limited rotation. A pin is embedded in the outer wall of the central shaft hole of the guide 330. The inner end of the pin is inserted into the annular groove on the outer wall of the convex shaft 321, thereby preventing the convex shaft 321 from slipping.

[0048] Another convex shaft 321 is inserted into and slides with the groove 331; the guide 330 is embedded in the inner corner of the package 100; since the pair of packages 100 are opened in a figure-eight shape and their two sides are not parallel, the pair of hinge frames 310 will interfere with the pair of packages 100 when they are closed; thus, the guide 330 supports the rotation of the steering rod 320, and the folding of the pair of hinge frames 310 and the closing of the pair of packages 100 are carried out simultaneously.

[0049] like Figure 6 As shown, a support strap 120 is provided between the middle of a pair of bag bodies 100 to support the shelf 220 and provide protection, preventing the shelf 220 from shaking. The support strap 120 is made of elastic band with a width of 100-150mm. Inserts 121 are provided at both ends of the support strap 120, and sleeves 130 are fitted over the inserts 121. The sleeves 130 are adhered to the inner wall of the bag body 100, allowing the support strap 120 to be easily replaced. The shelf 220 is available in multiple sizes based on commercially available laptops to allow for the selection of a suitable briefcase.

[0050] like Figure 7 As shown, a pad 110 is fixedly provided at the corner of the bottom surface of the bag body 100. The pad 110 is made of PP material and has a thickness of 4-5mm, making it shockproof and wear-resistant. A pad post 111 is vertically provided on the outer edge of the bottom surface of the pad 110, and a ground-supporting slope 112 is provided on the inner edge of the bottom surface of the pad 110. When the briefcase is closed, the pad post 111 provides support to prevent wear on the bottom surface of the bag body 100. When the briefcase is unfolded, the pad post 111 and the ground-supporting slope 112 provide adaptive support and play a role in preventing slippage.

[0051] When the layered laptop briefcase with wireless charging module of the present invention needs to be charged, the hidden connector between a pair of bag bodies 100 is opened, and the pair of bag bodies 100 are unfolded into a figure-eight shape. At the same time, the two pairs of hinge frames 310 will automatically deflect and unfold. Then, the pair of bag bodies 100 can be fully opened by pinching the two pairs of hinge frames 310. Then, the laptop is inserted into the shelf 220 and the battery area is facing the wireless charging module for charging, so that it can be opened quickly and easily when the laptop needs to be charged.

[0052] When in the office, the briefcase can be placed on the table and charged by an external power source. The two bag bodies 100 can be opened by the unfolding rack to keep the heat dissipation space open and ensure stable heat dissipation. When walking or riding in a vehicle, the briefcase can be carried by hand, and the two bag bodies 100 can be opened by the unfolding rack to keep the heat dissipation space open and ensure stable heat dissipation.

[0053] Example 2

[0054] Please see Figures 1-5 As shown, this invention provides a layered laptop briefcase with a wireless charging module, applicable to briefcases and laptop bags. The briefcase includes a pair of bag bodies 100 and a connecting strap 200 between their top edges. The bottom of the pair of bag bodies 100 can switch between an open and closed state. In the open state, a charging area 210 is formed between the pair of bag bodies 100, and a wireless charging module 230 is disposed within the charging area 210 for charging the laptop and maintaining airflow for timely heat dissipation during charging. A shelf 220 is glued or riveted below the connecting strap 200 for placing the laptop, and the wireless charging module 230 is embedded in the side wall of the shelf 220. Several ventilation windows 221 are provided on both sides of the shelf 220.

[0055] The wireless charging module 230 includes a main control PCB board, a transmitting coil, and a metal heat sink attached to the back of the PCB board. It is also equipped with an LED indicator to display the charging status and fault alarm. The wireless charging module 230 is equipped with a power cord for external power supply; or a battery pack can be configured on the shelf 220 for power supply. The above are existing technologies and will not be described in detail here.

[0056] Furthermore, a concealed connector is provided between the opposite sides of the pair of bag bodies 100, which can be closed by one of the following: zipper, Velcro, or snap fastener, so that it can be opened quickly and easily when the laptop needs to be charged.

[0057] Furthermore, a pair of unfolding racks are provided between the bottom side walls of the pair of bag bodies 100 to stabilize the space of the charging area 210; so that the pair of bag bodies 100 can be unfolded into a figure eight shape and stand stably, ensuring smooth heat dissipation of the charging area 210; or when carrying the briefcase, the unfolding racks can be used to open the pair of bag bodies 100 to keep the heat dissipation space open and to ensure stable heat dissipation.

[0058] like Figures 8-11 As shown, this is another form of the display rack structure. The display rack is a folding component 400, which consists of a pair of folding frames 410, a pair of fixing rods 420, and a hinge block 430. One end of the folding frame 410 is hinged to the fixing rod 420. The hinge block 430 is a trapezoidal block with its cone angle equal to the maximum angle of the package 100 when unfolded. The other end of the folding frame 410 is hinged to the hypotenuse of the hinge block 430. The fixing rod 420 is glued or riveted to the bottom corner of the inner side of the package 100. Since the pair of packages 100 are opened in a figure-eight shape and their two sides are not parallel, the addition of the hinge block 430 structure allows the pair of folding frames 410 to be folded and closed directly by utilizing its hypotenuse parallel to the unfolded hypotenuse of the package 100. This is another way of displaying and folding.

[0059] like Figure 6 As shown, a support strap 120 is provided between the middle of a pair of bag bodies 100 to support the shelf 220 and provide protection, preventing the shelf 220 from shaking. The support strap 120 is made of elastic band with a width of 100-150mm. Inserts 121 are provided at both ends of the support strap 120, and sleeves 130 are fitted over the inserts 121. The sleeves 130 are adhered to the inner wall of the bag body 100, allowing the support strap 120 to be easily replaced. The shelf 220 is available in multiple sizes based on commercially available laptops to allow for the selection of a suitable briefcase.

[0060] like Figure 7 As shown, a pad 110 is fixedly provided at the corner of the bottom surface of the bag body 100. The pad 110 is made of PP material and has a thickness of 4-5mm, making it shockproof and wear-resistant. A pad post 111 is vertically provided on the outer edge of the bottom surface of the pad 110, and a ground-supporting slope 112 is provided on the inner edge of the bottom surface of the pad 110. When the briefcase is closed, the pad post 111 provides support to prevent wear on the bottom surface of the bag body 100. When the briefcase is unfolded, the pad post 111 and the ground-supporting slope 112 provide adaptive support and play a role in preventing slippage.

[0061] When the layered laptop briefcase with wireless charging module of the present invention needs to be charged, the hidden connector between a pair of bag bodies 100 is opened, and the pair of bag bodies 100 are unfolded into a figure-eight shape. At the same time, the two pairs of folding frames 410 will automatically unfold. Then, the pair of bag bodies 100 can be fully opened by pinching the two pairs of folding frames 410. Then, the laptop is inserted into the shelf 220, and the battery area is facing the wireless charging module for charging, so that it can be opened quickly and easily when the laptop needs to be charged.

[0062] When in the office, the briefcase can be placed on the table and charged by an external power source. The two bag bodies 100 can be opened by the unfolding rack to keep the heat dissipation space open and ensure stable heat dissipation. When walking or riding in a vehicle, the briefcase can be carried by hand, and the two bag bodies 100 can be opened by the unfolding rack to keep the heat dissipation space open and ensure stable heat dissipation.

[0063] It should be noted that the fixed connections and fixing methods of the present invention are implemented using conventional fixing means such as bolt connections or welding that are compatible with each other. The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and should not be used to limit the scope of protection of the present invention.
