Description

Technical Field

[0001] This utility model relates to the field of luggage wheel power generation technology, and more specifically, to a luggage wheel power generation and built-in battery charging structure. Background Technology

[0002] With the widespread use of mobile electronic devices and the growth of business travel demand, traditional suitcases are gradually developing towards intelligence. Roller-powered charging systems capture the kinetic energy of suitcases during movement and convert it into electrical energy. This not only solves the emergency charging needs in outdoor scenarios but also aligns with the concepts of green energy and sustainable design, making it an important direction for innovation in travel equipment.

[0003] Existing publication number CN115473380B discloses a mechanical self-generating suitcase, including a suitcase body, a power generation and charging module, and casters. The power generation and charging module is installed inside the suitcase body. There are four casters, one of which is a working wheel. The power generation and charging module is connected to the working wheel via a transmission device. The transmission device includes a suitcase body transmission component, a connecting component, and a working wheel transmission component. When people urgently need to charge while traveling, they only need to pull the suitcase to charge the power bank inside. The power bank can then charge portable electronic devices such as mobile phones without limitations or unstable output current. It ensures that the energy generated while walking is not wasted and is converted into electrical energy stored in the power bank. It can convert the energy generated while walking into electrical energy and store the generated electrical energy to charge mobile phones and small electronic devices. The current is stable, and there is no need to carry power banks or other charging equipment, making it convenient for travelers. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] The existing suitcases generate electricity by converting kinetic energy into electrical energy and storing it in batteries. However, the existing generators are prone to overheating during the conversion process, which may lead to excessively high internal temperatures in the suitcase and a significant reduction in generator efficiency.

[0005] Therefore, a luggage wheel power generation and built-in battery charging structure is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a luggage wheel power generation and built-in battery charging structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a luggage wheel power generation and built-in battery charging structure, comprising a luggage body, a power generation wheel installed at the bottom of the luggage body; a first wire connected to the top of the power generation wheel; the first wire located inside the luggage body, a permanent magnet generator installed in the middle of the luggage body; the end of the first wire connected to the permanent magnet generator; a second wire fixedly connected to the top of the permanent magnet generator; a lithium-ion battery installed at the end of the second wire; a heat dissipation copper fin provided on the side wall of the permanent magnet generator; multiple heat conduction pillars fixedly connected to the side wall of the heat dissipation copper fin; a heat dissipation plate fixedly connected to the end of the heat conduction pillar; the heat dissipation plate fixedly connected to the side wall of the luggage body; and multiple heat dissipation fins connected to the side wall of the heat dissipation plate by hinges.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with the prior art, this luggage wheel power generation and built-in battery charging structure uses heat dissipation copper fins, heat conduction columns, and heat dissipation plates to dissipate the surface temperature of the permanent magnet generator. When the luggage moves, the generator wheel rotates, and the permanent magnet generator can convert its kinetic energy into electrical energy, which is then transmitted to the lithium-ion battery for storage through a second wire. When the permanent magnet generator is working, it generates heat. At this time, the heat dissipation copper fins can conduct the surface heat of the permanent magnet generator to the heat dissipation plate through the heat conduction columns, and then conduct it to the outside of the luggage for cooling. This setting can reduce the situation where the heat generated by the permanent magnet generator is too high and heat accumulates inside the luggage, which would lead to a significant reduction in the generator's power generation efficiency.

[0017] 2. Compared with the prior art, the luggage wheel power generation and built-in battery charging structure can improve the charging speed of lithium-ion batteries by setting a solar power panel on the outside of the luggage body. The solar power panel can collect solar energy and then convert it into electrical energy through a solar controller, and then store it in the lithium-ion battery through a third wire, thereby accelerating its charging speed.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] As attached Figures 1 to 6 The diagram illustrates a luggage wheel power generation and built-in battery charging structure, comprising a luggage body 1, with a power generation wheel 11 mounted at the bottom of the luggage body 1; a first wire 12 connected to the top of the power generation wheel 11; the first wire 12 located inside the luggage body 1, and a permanent magnet generator 13 mounted in the middle of the luggage body 1; the end of the first wire 12 connected to the permanent magnet generator 13; a second wire 14 fixedly connected to the top of the permanent magnet generator 13; a lithium-ion battery 15 mounted at the end of the second wire 14; a heat dissipation copper fin 16 provided on the side wall of the permanent magnet generator 13; multiple heat conduction pillars 17 fixedly connected to the side wall of the heat dissipation copper fin 16; a heat dissipation plate 18 fixedly connected to the end of the heat conduction pillars 17; the heat dissipation plate 18 fixedly connected to the side wall of the luggage body 1; and multiple heat dissipation fins 19 connected to the side wall of the heat dissipation plate 18 via hinges.

[0028] Specifically: When the housing 1 moves, the generator wheel 11 rotates, and the permanent magnet generator 13 converts its kinetic energy into electrical energy, which is then transmitted to the lithium-ion battery 15 for storage through the second wire 14. When the permanent magnet generator 13 is working, it generates heat. At this time, the heat dissipation copper fin 16 can conduct the surface heat of the permanent magnet generator 13 to the heat dissipation plate 18 through the heat conduction column 17, and then conduct it to the outside of the housing 1 through the heat dissipation fins 19 for cooling. The angle of the heat dissipation fins 19 can be adjusted by using the hinge, so that when heat dissipation is not required, the heat dissipation fins 19 can be adjusted to a suitable position to prevent damage. By cooling the permanent magnet generator 13, the accumulation of heat inside the housing 1 due to the excessive heat generated by the permanent magnet generator 13 can be reduced, thereby reducing the power generation efficiency of the permanent magnet generator 13.

[0032] In a preferred embodiment, a first fixing frame 3 is fixedly connected to the inner side wall of the housing 1; a plurality of support columns 31 are fixedly connected to the top of the first fixing frame 3; a second fixing frame 32 is fixedly connected to the top of the plurality of support columns 31; furthermore, the first fixing frame 3 and the second fixing frame 32 can fix the permanent magnet generator 13 and the lithium-ion battery 15.

[0034] In a preferred embodiment, a third wire 5 is installed on the top of the lithium-ion battery 15; a solar controller 51 is installed at the end of the third wire 5; a solar power panel 52 is installed on the side wall of the solar controller 51; furthermore, the solar power panel 52 can collect solar energy and then convert it into electrical energy through the solar controller 51, and store it in the lithium-ion battery 15 through the third wire 5, thereby accelerating its charging speed.

[0035] In a preferred embodiment, a lead plate 6 is fixedly connected to the end of the third lead 5; the lead plate 6 is threadedly connected to the lithium-ion battery 15; furthermore, the lead plate 6 can fix the third lead 5 to the top of the lithium-ion battery 15, making the connection more stable.

[0036] In a preferred embodiment, a support block 7 is fixedly connected to the side wall of the housing 1; a fan 71 is fixedly connected to the top of the support block 7; furthermore, starting the fan 71 can extract the air inside the housing 1, thereby improving the heat dissipation effect of the equipment.

[0037] In a preferred embodiment, a hollow box 8 is fixed to the surface of the housing 1; the surface of the hollow box 8 is provided with a plurality of heat dissipation holes 81; furthermore, the hollow box 8 can prevent external debris from entering the middle of the fan 71, thereby extending the service life of the fan 71.

They can be customized or selected according to actual needs. Here, we are only using them and have not made any structural or functional improvements. We will not go into details here.

[0039] The working process of this utility model is as follows: First, when the housing 1 moves, the sponge 4 can absorb part of the vibration generated when the housing 1 moves, and then the generator wheel 11 rotates. The first fixing frame 3 and the second fixing frame 32 can fix the permanent magnet generator 13 and the lithium-ion battery 15. The permanent magnet generator 13 can convert its kinetic energy into electrical energy, which is then transmitted to the lithium-ion battery 15 for storage through the second wire 14.

In battery 15, when the permanent magnet generator 13 is working, it generates heat. At this time, the first magnetic block 2 can be attracted to the second magnetic block 21, reducing the gap between the permanent magnet generator 13 and the heat sink copper plate 16. Then, the heat sink copper plate 16 can conduct the surface heat of the permanent magnet generator 13 through the heat conduction column 17 to the heat sink 18 and then through the heat sink fins 19 to the outside of the box 1 for cooling. At the same time, the fan 71 can be turned on to draw out the air inside the box 1, improving the heat dissipation effect of the device. The hollow box 8 can prevent foreign objects from entering the middle of the fan 71. The above is the working principle of this luggage wheel power generation and built-in battery charging structure.
