Description

Technical Field

[0001] This utility model relates to the field of power generation equipment, specifically to a portable generator. Background Technology

[0002] Hiking is an activity that involves walking to natural or outdoor areas such as the suburbs or mountains. Participants can plan their own routes or follow established trails, enjoying the scenery along the way and experiencing the changing seasons. It combines exploration and leisure.

[0003] Carrying electrical devices during hiking can greatly enhance the hiking experience and convenience, which is beneficial for first-time hikers and encourages them to further explore hiking and outdoor activities. However, during long hiking trips, the power supply for electrical devices is an issue that cannot be ignored. Carrying fuel generators poses pollution problems, while carrying energy storage devices is inconvenient due to their large size and weight. Therefore, providing a portable, efficient, and reliable device to power electrical devices can greatly improve the hiking experience. Utility Model Content

[0004] The technical problem to be solved by this invention is to provide a stable and reliable power source for electrical appliances during hiking, while also making it easy to move and carry. Therefore, a portable generator is provided.

[0005] A portable generator adopts the following technical solution:

[0006] A portable generator for outdoor power generation includes a bracket, an electromagnetic induction component, and a wind power component. The wind power component includes a rotating shaft and at least two inflatable fan blades disposed on the rotating shaft. The inflatable fan blades include a concave surface and a convex surface arranged in parallel, and the curved edge length of the concave surface is less than the curved edge length of the convex surface.

[0007] By adopting the above technical solution, after the inflatable wind blade is fully inflated, the curved edge length of the concave surface is less than that of the convex surface, which ensures that the inflatable wind blade can rotate stably under the action of airflow, and will not be unable to generate electricity by utilizing airflow due to insufficient force-bearing area of ​​the wind blade.

[0008] Furthermore, a transition surface is provided on the side of the concave surface and the convex surface away from the rotating shaft, and the width of the transition surface is the same as the thickness of the fan blade.

[0009] The transition surface helps to further expand the force-bearing area. At the same time, due to the lever principle, the shaft can be considered as the fulcrum, and the transition surface, as the farthest point from the fulcrum, can drive the shaft to rotate faster, thereby increasing the power generation speed and output.

[0010] Furthermore, the thickness of the blade does not exceed the length of the concave curved edge, and it has a supporting thickness that prevents the inflatable blade from being deformed by wind pressure during power generation after it is fully inflated.

[0011] The concave surface further increases the stress-bearing area, and also makes the inflatable wind blades bear force evenly during power generation, ensuring the stability of the current during power generation, especially when powering electrical appliances through direct power generation; the support thickness is used to prevent the inflatable wind blades from deforming when the wind force is too strong, and the value is between one-third and one-quarter of the width of the concave surface.

[0012] To further improve the stable rotation of the shaft during power generation, the inflatable fan blades are evenly distributed circumferentially along the shaft.

[0013] Furthermore, the support includes a fixed pile and a support foot arranged coaxially with the rotating shaft, and a counterweight is provided at the bottom of the fixed pile.

[0014] Counterweights can effectively lower the center of gravity of the entire structure and improve stability.

[0015] To improve the stability of the portable generator on soft, uneven surfaces such as grass, the support foot is further provided with a spike, and the side of the spike is provided with a pin, so that the portable generator can be inserted into the soft, uneven surface through the spike, and the movement of the spike is restricted by the fixing pin, so as to finally achieve the purpose of fixing the generator.

[0016] Furthermore, the support leg is provided with a slide that engages with the pin.

[0017] Preferably, the slide rail has at least one receiving pin to prevent the needle tip from extending beyond the first receiving groove of the support foot, and one receiving pin to allow the needle tip to fully protrude from the second receiving groove of the support foot.

[0018] The first receiving groove can prevent the generator from being vibrated during transportation, which could cause the needle to come out. The second receiving groove facilitates the application of force when the needle is inserted into an uneven surface.

[0019] Furthermore, the support foot includes a first link and a second link, and the support foot is connected to the fixed pile through the first link and the second link.

[0020] This further reduces the size when stored, improving portability.

[0021] Furthermore, the electromagnetic induction component also includes an energy storage component and an indicator light.

[0022] This allows the generator to supply power to electrical appliances directly, or to store electricity in advance through wind power generation. This avoids situations where there is no wind at the destination and the electrical appliances cannot be powered directly. At the same time, the indicator lights can also intuitively display the power status of the energy storage components.

[0023] In summary, this application contains at least one of the following beneficial effects:

[0024] 1. The concave and convex surfaces of the inflatable fan blades effectively collect and homogenize wind power, thereby driving the shaft to rotate stably and continuously. After inflation, the concave and convex surfaces maintain the shape of the inflatable fan blades, enabling them to effectively convert wind power to drive the shaft to rotate rather than deform and cause low power generation efficiency. The transition surface, as the farthest point from the shaft, can provide a greater tangential force to the shaft, increasing the power generation speed and increasing the power output.

[0025] 2. The needle is positioned by a pin, and the first and second receiving grooves on the slide can be used to adjust the position of the needle, making it easy to insert into the soft non-flat surface. At the same time, it works with the counterweight to lower the center of gravity, improving its stability when installed on the non-flat surface. The folding of the first and second connecting rods effectively reduces the volume after storage and improves portability.

[0026] 3. The energy storage component enables the generator to supply power to electrical appliances directly, or to store energy in advance through wind power generation. This avoids situations where there is no wind at the destination and the electrical appliances cannot be powered directly by generating electricity. The indicator light can also intuitively display the power status of the energy storage component. Attached Figure Description

[0031] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0032] Example 1

[0033] refer to Figure 1 , 2 A portable generator includes a bracket 2, an electromagnetic induction component (located within a fixed stake 21 and electrically connected to an energy storage component 5), and a wind turbine component 1. The wind turbine component 1 includes at least two inflatable fan blades 11 and a shaft 16. (Refer to...) Figure 1 This application describes two inflatable fan blades 11. Each inflatable fan blade 11 includes a concave surface 12 and a convex surface 13 arranged parallel to each other. A transition surface 15 is provided on the side of each blade away from the rotating shaft 16. The width of the transition surface 15 is equal to the distance between the concave surface 12 and the convex surface 13. It should be noted that the inflatable fan blade 11 has a support thickness, which is between one-third and one-quarter of the width of the concave surface 12. This support thickness can effectively prevent the inflatable fan blade 11 from deforming under the action of wind. Both the concave surface 12 and the convex surface 13 of the inflatable fan blade 11 have curved edges 14. The length of the curved edge 14 of the concave surface 12 is not greater than the length of the curved edge 14 of the convex surface. The inflatable fan blades 11 are evenly distributed on the side wall of the rotating shaft 16.

[0034] refer to Figure 1 , 2 The support 2 includes a fixed pile 21 and support feet 23 evenly distributed around the fixed pile 21. The bottom of the fixed pile 21 is provided with a counterweight 22. The support feet 23 include a first connecting rod 24 and a second connecting rod 25. The first connecting rod 24 is provided with a needle 3. The first connecting rod 24 is connected to the fixed pile 21, but not the counterweight 22, through the second connecting rod 25.

[0035] Combination Figure 2 , 3 The needle 3 also has a pin 31 on its side, and the first connecting rod 24 has a slide 4 that mates with the pin 31. (See further reference.) Figure 3 The slide 4 includes at least a first receiving groove 41 and a second receiving groove 42. In this embodiment, it also includes a third receiving groove 43. The first receiving groove 41 is used to receive the pin 31 so that the needle 3 is completely contained within the support foot 23. The second receiving groove 42 is used to receive the pin 31 so that the tip of the needle 3 is completely exposed outside the support foot 23. The third receiving groove is used to receive the pin 31 so that the needle 3 can further penetrate into the non-planar surface.

[0036] Refer again Figure 1 , 2The electromagnetic induction component (not shown in the figure) is located inside the fixed pile 21. The end of the rotating shaft 16 installed inside the electromagnetic induction component is provided with a magnet for cutting magnetic field lines to generate induced current during the rotation of the rotating shaft 16. The fixed pile 21 is also provided with a power storage component 5 and an indicator light 6. The power storage component 5 is electrically connected to the electromagnetic induction component, and the indicator light 6 is electrically connected to the power storage component 5. It should be noted that both the power storage component 5 and the electromagnetic induction component include an interface for directly supplying power to electrical appliances (not shown in the figure).

[0037] The installation and power generation processes of the portable generator will now be explained with reference to the accompanying drawings:

[0038] refer to Figure 1 When needed, first unfold the inflatable fan blades 11 and inflate them until they are fully expanded, refer to... Figure 2 Open the first link 24 and the second link 25 to deploy the support leg 23, see reference. Figure 3 Move the pin 31 from the first receiving groove 41 to the second receiving groove 42. At this time, force is applied to the first connecting rod 24 and the second connecting rod 25 to make the needle 3 penetrate the non-flat surface, thereby fixing the support foot 23. If the support foot 23 is still unstable at this time, the pin 31 can be moved into the third receiving groove 43 by stepping on it to deepen the depth of the needle 3. This works in conjunction with the counterweight 22 of the fixing pile 21 used to lower the center of gravity of the portable generator, thereby further improving the overall installation stability. The installation of the portable generator is thus completed.

[0039] After installation, wind power can be collected to supply power to electrical equipment or energy storage component 5. When power is supplied to energy storage component 5, indicator light 6 is used to visually display the amount of energy stored in energy storage component 5.

[0040] After the power supply process is completed, the installation process of the portable generator is reversed to complete the storage of the portable generator, which will not be described in detail here.

[0041] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
