[0044] The utility model provides a kind of travel bag including bag body, the mobile power supply is built-in in the bag body, the mobile power supply has portable power generation device.

[0045] As shown in Figures 1 to 6 The portable power generation device of the embodiment includes a housing 100, the housing 100 is built-in with a power generation assembly 200 and a power supply assembly 300, wherein the power supply assembly 300 includes a capacitor 310, a battery pack 320 and a rectifier 330, the battery pack 320 is arranged on the side of the power generation assembly 200, and the rectifier 330 is installed above the power generation assembly 200.

[0046] Combined Figures 2 to 5As shown, the power generation component 200 includes a fixing base 210 with a central through hole, a copper coil 220 wound on the fixing base 210, and a strong magnetic block 230 that can move along the central through hole, baffles 23 are provided at both ends of the strong magnetic block 230, at least two stop protrusions 232 are staggered on the circumferential outer surface of the strong magnetic block 230, and stop flanges 211 are provided at the two end edges corresponding to the central through hole. Through the cooperation of the stop protrusion 232 and the stop flange 211, the movement position of the strong magnetic block 230 in the central through hole can be limited; the battery pack 320 is electrically connected to one end of the rectifier 330, and the copper coil 220 is electrically connected to the other end of the rectifier 330.

[0047] The present invention maximizes the movement range of the strong magnetic block 230 through the cooperation between the internal stop protrusion 232 and the stop flange 211, thereby generating as much electricity as possible to meet the requirements of use while ensuring safe and reliable use.

[0048] The utility model utilizes the shaking of the power source itself to make the strong magnetic block move up and down reciprocatingly inside the coil, thereby generating a charging current. Therefore, charging is both environmentally friendly and convenient, and there are fewer factors that limit charging.

[0049] The battery pack 320 is a rechargeable lithium power source. The lithium power source can not only be repeatedly charged and discharged multiple times, thereby extending the service life of the mobile power source, but also has a light weight, which is convenient for carrying.

[0050] In this embodiment, the stop protrusions 232 are symmetrically distributed along the outer circumferential surface, for example Figure 4 There are stop protrusions 232 distributed in the middle, symmetrically distributed along the central axis; the stop protrusions 232 are made of flexible material and are fixed to the strong magnetic block 230 by inlaying and / or bonding. The flexible material has a certain anti-collision strength, and when the strong magnetic block 230 moves back and forth and collides with the stop flange 211, the reliability of use can be ensured. The preferred flexible material can use commercially available furan graphite composite materials.

[0051] In addition, the fixing seat 210 is made of hard plastic, such as phenolic plastic, polyurethane plastic, epoxy plastic, etc., which has non-conductive properties.

[0052] When in use, especially in the wild, in order to prevent some impurities from entering the USB interface 120, the device further includes a protective layer 400, which is fixed on one side of the housing 100 and adhered to the housing 100 on the other side (for example Figure 1 The adhesive tape 410 is used and can cover the USB interface 120. During normal use, the protective layer 400 covers the USB interface 120.

[0053] In use, the strong magnetic block 230 interacts with the copper coil 220, a part of energy is converted into heat, and the rectifier 330 also generates heat, in the small closed space of the shell 100, the heat will gather, thereby affecting the normal work of the battery pack 320, especially the lithium power supply, therefore, the heat dissipation through hole 110 is arranged at the position corresponding to the power generation assembly 200 and the rectifier 330 of the shell 100. The USB interface 120 is arranged on the shell 100, the USB interface 120 is electrically connected with the battery pack 320, and the USB interface 120 can provide a charging power supply for a mobile phone and the like.

[0054] It should be noted that the heat dissipation through hole 110 is away from the protective layer 400 and cannot be covered by the protective layer 400, so as to avoid affecting the heat dissipation.

[0055] At the same time, as shown in the figure, the surface of the heat dissipation through hole 110 is covered with a breathable film 140, which can prevent dust from entering the inside of the shell 100 while ensuring heat dissipation. Preferably, the breathable film 140 can be selected from PUW875 high molecular waterproof breathable film 140, PVC waterproof breathable film 140 and the like, which not only has the function of heat dissipation, but also has the effect of waterproofing. Figure 6

[0056] Further, the shell 100 is cylindrical in outer contour, and the LED lamp bead 130 is arranged on any end surface on both sides of the central axis of the shell 100, the lamp bead 130 is electrically connected with the battery pack 320 and is provided with a switch (not marked in the figure), and the energy required by the LED lamp bead 130 is small.

[0057] The above-mentioned electrical connection is generally connected by a wire unless otherwise specified, for example, Figure 2 In the figure, wires are used to connect each component, such as between the rectifier and the capacitor, between the battery pack and the lamp bead, and between the capacitor and the like.

[0058] The above describes the utility model and its implementation mode schematically, which is not restrictive, and the figure only shows one of the implementation modes of the utility model, and the actual structure and manufacturing steps are not limited thereto. Therefore, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structure modes and embodiments can be designed without creativity, which should all belong to the protection scope of the utility model.​
