Description

Technical Field

[0001] This invention relates to the field of mobile photovoltaic power technology, specifically a solar-powered mobile power supply. Background Technology

[0002] Existing solar-powered mobile power banks are power supply devices that integrate photovoltaic panels and energy storage units, capable of converting solar energy into electrical energy and storing it to provide power for various electronic devices. However, these products still have several limitations at the technical level that urgently need to be addressed.

[0003] First, the portability requirements of portable power banks necessitate a small size and weight, directly limiting the area of ​​the photovoltaic panels. Since photovoltaic power generation is positively correlated with the area exposed to sunlight and the intensity of sunlight, this size constraint leads to low power generation efficiency and charging rates that fail to meet practical needs. Second, most photovoltaic panels on the market currently use a fixed design, making it impossible to adjust the angle according to the sun's position. This results in a significant amount of sunlight being wasted due to an unfavorable incident angle, further reducing energy conversion efficiency.

[0004] Therefore, a solar-powered mobile power source is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a solar-powered mobile power supply to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a solar-powered portable power supply, comprising a portable power supply, a support and adjustment assembly, the support and adjustment assembly comprising two slot blocks, the two slot blocks being symmetrically fixedly connected to both sides of the portable power supply, each slot block containing a slider, each end of the two sliders being fixedly connected to a rotating shaft, the two rotating shafts on the same slider being rotatably connected to the same rotating plate, each rotating plate having three photovoltaic panels slidably connected to each of the two rotating plates, each rotating plate having a fixedly connected connecting slot block, the two connecting slot blocks having a common two-in-one power cord inserted therein, each of the two rotating shafts on the side away from the connecting slot block having a fixedly connected locking shaft at one end extending from the rotating plate, each of the two rotating plates having a fixedly connected threaded tube at one end near the locking shaft, each of the two threaded tubes having a threaded post threadedly connected inside, each of the two threaded posts having a fixedly connected pressure plate at one end away from the rotating plate, each of the two pressure plates having multiple anti-slip grooves on the side near the rotating plate, and each of the two pressure plates having a fixedly connected rotating block on the side away from the rotating plate.

[0007] Furthermore, each of the two rotating plates is fixedly connected to a slot block 2, and each of the two slot blocks 2 contains a plug. The top of the two plugs is fixedly connected to a sun protection strip. Multiple heat dissipation holes are opened on both sides of the power bank.

[0008] Furthermore, the power bank has charging and discharging ports on its side wall.

[0009] Furthermore, the three photovoltaic panels on the same rotating plate are arranged in a vertical straight-line array.

[0010] Furthermore, the two-in-one power cord has two branched plugs on one side and a single plug on the other side.

[0011] Furthermore, the locking shaft is made of rubber.

[0012] Furthermore, the sun protection band is used to insulate and cool the power bank.

[0013] Furthermore, the heat dissipation holes are used to connect the inside of the power bank with the external environment for heat dissipation and cooling.

[0014] Compared with the prior art, the beneficial effects of the present invention are: Firstly: Due to portability requirements, existing products have fixed and small photovoltaic panel areas, resulting in insufficient power generation capacity.

[0015] By supporting the operation of the adjustment components, a photovoltaic module that can be freely disassembled and folded is designed. When not in use, it can be stored to ensure portability. When in use, it can be folded and extended to greatly expand the light-receiving area, which solves the limitation of fixed area light-receiving in traditional technology, increases the amount of solar energy absorbed per unit time, and improves the efficiency of photovoltaic power supply for charging mobile power.

[0016] Secondly: Existing fixed photovoltaic panels cannot adjust their angle according to the sun's position, resulting in a large amount of sunlight not being effectively utilized due to poor incident angles.

[0017] By supporting the operation of the adjustment components, the photovoltaic modules on both sides of the power bank can rotate freely relative to the power bank. With the angle adjustment and locking functions of the adjustment components, users can freely adjust and lock the angle of the photovoltaic modules according to the position of the sun, ensuring that the photovoltaic panels are always facing the sun at the optimal angle, minimizing sunlight waste and improving energy conversion efficiency.

[0018] Thirdly: Existing products are prone to overheating due to poor heat dissipation under strong light, which accelerates aging and poses safety risks.

[0019] By supporting the operation of the adjustment components, the design incorporates physical sun protection and heat insulation of the sun protection band and heat dissipation and cooling through the heat dissipation holes, which can insulate and cool the power bank and prevent it from overheating under direct sunlight.

[0020] Furthermore, by supporting the operation of the adjustment components, a detachable photovoltaic module and a detachable cooling function are designed. When the photovoltaic module is not in use, the module and cooling structure can be disassembled, making the power bank compact and portable. When in use, the adjustment components can be installed for heat insulation charging, taking into account both the needs of daily portability and efficient power generation.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] The embodiments provided by this invention: Please see Figures 1 to 8 As shown, a solar-powered mobile power supply includes a mobile power supply 11.

[0025] Among them: the power bank 11 is a known existing technology, and the power bank 11 has a charging hole and a discharging hole on its side wall.

[0026] The power bank 11 is equipped with a support adjustment assembly, which includes two slot blocks 21. The two slot blocks 21 are symmetrically fixedly connected to both sides of the power bank 11. Each slot block 21 has a slider 22 inserted inside. Each end of the two sliders 22 is fixedly connected to a rotating shaft 23. The two rotating shafts 23 on the same slider 22 are rotatably connected to the same rotating plate 24. Three photovoltaic panels 25 are slidably connected to each of the two rotating plates 24. Each rotating plate 24 is fixedly connected to a connecting slot block 26. A two-in-one power cord 27 is inserted into the two connecting slot blocks 26. The ends of the two rotating shafts 23 on the side away from the connecting slot block 26 that protrude from the rotating plates 24 are each fixedly connected to a locking shaft 28. Each of the two rotating plates 24 near the locking shaft 28 is fixedly connected to a threaded tube 29. Each of the two threaded tubes 29 is threadedly connected to a threaded post 210. Each of the two threaded posts 210 away from the rotating plate 24 is fixedly connected to a pressure plate 211. Each of the two pressure plates 211 near the rotating plate 24 is provided with multiple anti-slip grooves 212. Each of the two pressure plates 211 away from the rotating plate 24 is fixedly connected to a rotating block 213. Each of the two rotating plates 24 is fixedly connected to a slot block 214. Each of the two slot blocks 214 is inserted with a plug 215. The tops of the two plugs 215 are fixedly connected to a sunshade strip 216. The power bank 11 is provided with multiple heat dissipation holes 217 on both sides near the two slot blocks 21.

[0027] Where: Reference Figure 1 As shown, the three photovoltaic panels 25 on the same rotating plate 24 are arranged in a vertical straight array. The two photovoltaic panels 25 on the top and bottom sides of the same rotating plate 24 can be pulled apart by the user to expose the top surfaces of the three photovoltaic panels 25, thus obtaining a larger photovoltaic light-receiving surface.

[0028] The function of the rotating plate 24 and the slider 22 being rotatably connected by the rotating shaft 23 is to allow the rotating plate 24 to be rotated by the user on the mobile power supply 11, so that the photovoltaic light-collecting surfaces of the three rotating plates 24 face the direction of direct sunlight.

[0029] The connection between the slot block 21 and the slider 22 is to allow the slider 22, the rotating plate 24 and the photovoltaic panel 25 to be freely installed and removed from the power bank 11 by the user, thereby enabling the power bank 11 to switch between photovoltaic charging and normal use functions. Furthermore, the photovoltaic accessories can be removed when the power bank 11 is in normal use, thus meeting the portability requirements of the power bank 11.

[0030] In summary: the slider 22, the two rotating shafts 23, the rotating plate 24 and the three photovoltaic panels 25 form a single photovoltaic module, that is, two sets of photovoltaic modules that can be freely disassembled and rotated by the user are set on both sides of the power bank 11.

[0031] Wherein: the connecting slot 26 and the two-in-one power cord 27 are existing known structures. One side of the two-in-one power cord 27 is provided with two branched plugs, and the other side is provided with a single plug. The two branched plugs of the two-in-one power cord 27 are respectively plugged into the two connecting slots 26, and the plug on the other side is plugged into the charging port on the power bank 11. The function of the two-in-one power cord 27 is to transmit the photovoltaic power generated by the photovoltaic panel 25 to the power bank 11, so that the power bank 11 can perform solar charging.

[0032] Among them, the locking shaft 28 is made of rubber, and its function is to increase friction.

[0033] Where: Reference Figure 7 As shown, the function of the rotating block 213 is to facilitate the user to rotate the pressure plate 211.

[0034] As a supplement to the previous point: the user can rotate the pressure plate 211 to loosen and tighten the threads of the threaded post 210 inside the threaded tube 29. When the threads of the threaded post 210 are tightened, the pressure plate 211 moves closer to the locking shaft 28, causing the anti-slip groove 212 on the pressure plate 211 to abut against the locking shaft 28. Under the pushing force provided by the tightening of the threads of the threaded post 210 and the friction provided by the anti-slip groove 212, the locking shaft 28 is locked and limited, meaning that the locking shaft 28 can no longer rotate. Similarly, when the user loosens the threads of the threaded post 210, the anti-slip groove 212 on the pressure plate 211 no longer abuts against the locking shaft 28, at which point the locking shaft 28 is released from its limit.

[0035] As a supplement to the previous one: when the locking shaft 28 is locked and limited by the pressure plate 211 and the anti-slip groove 212, the rotating plate 24 can no longer rotate on the rotating shaft 23. That is, the rotation angle of the rotating plate 24 on the rotating shaft 23 is fixed. That is, the rotation angle of the three photovoltaic panels 25 on the same side after unfolding and the mobile power supply 11 is locked and limited. That is, the angle of the photovoltaic light-collecting surface of the three rotating plates 24 facing the direct light direction is limited.

[0036] The connection between slot 214 and plug 215 serves to facilitate the user's free removal and installation of the sun protection strip 216 from the power bank 11. The sun protection strip 216 is made of polyester fiber with a sun protection coating, which has the function of blocking sunlight and providing physical heat insulation. The sun protection strip 216 is used to insulate the power bank 11 from heat and prevent it from overheating under direct sunlight.

[0037] Where: Reference Figure 4As shown, the heat dissipation hole 217 is used to connect the inside of the power bank 11 with the external environment, so as to facilitate heat dissipation inside the power bank 11.

[0038] It should be noted that the two slot blocks 21 and the two sliders 22, as well as the two slot blocks 214 and the two plugs 215, are all designed to be connected by T-shaped slots and T-shaped blocks. They can be connected by horizontal movement and will not come loose when pulled vertically, thus ensuring the stability of the connection.

[0039] In summary, when the support adjustment components are not in use, i.e. when the mobile power supply 11 does not need to be charged by solar energy, the two sliders 22 are not inserted into the corresponding slot block 1 21, the three photovoltaic panels 25 on the same rotating plate 24 are not extended, and the two sun protection strips 216 are not inserted into the two slot blocks 214.

[0040] When the support adjustment component is in use, i.e. when the power bank 11 needs to be solar charged, the user inserts the two sliders 22 into the slot blocks 21 on both sides of the power bank 11, and then extends the three photovoltaic panels 25 on the same rotating plate 24, exposing the top surfaces of the three photovoltaic panels 25. After completion, the user inserts the two forked ends of the two-in-one power cord 27 into the two connecting slot blocks 26, and connects the other end of the two-in-one power cord 27 to the charging port of the power bank 11. At this time, the photovoltaic light-receiving surface of the photovoltaic panel 25 receives sunlight, and the photovoltaic panel 25 charges the power bank 11 through the two-in-one power cord 27, i.e., the power bank 11 is solar charged.

[0041] After completion, the user rotates the rotating plate 24 to change the orientation angle of the photovoltaic panels 25 on both sides of the slot block 21. When the orientation angle of the photovoltaic panel 25 is the same as the direct angle of the light in the external environment, the user rotates the corresponding pressure plate 211 through the two rotating blocks 213, so that the threaded post 210 is tightened in the threaded tube 29. As the threaded post 210 is tightened, the pressure plate 211 moves closer to the locking shaft 28, so that the anti-slip groove 212 on the pressure plate 211 abuts against the locking shaft 28. Then, under the pushing force provided by the threaded post 210 and the friction provided by the anti-slip groove 212, the locking shaft 28 is locked and limited, that is, the locking shaft 28 can no longer rotate. At this time, the rotating plate 24 can no longer rotate on the rotating shaft 23, that is, the state in which the multiple photovoltaic panels 25 on both sides of the power bank 11 face the direct light in the external environment is fixed.

[0042] Since the angle of sunlight in the external environment will change over time, the user can loosen the threaded post 210 to release the limiting state of the photovoltaic module, adjust the rotation angle of the rotating plate 24 on the slider 22, so that the photovoltaic panel 25 always faces the angle of sunlight. After completion, the user can tighten the threaded post 210 again.

[0043] During the above process, the user inserts the two plugs 215 into the two slot blocks 214 respectively. As the two plugs 215 are connected, the sun protection strip 216 covers the top of the power bank 11. However, the sun protection strip 216 does not cover the multiple photovoltaic panels 25 on both sides of the power bank 11. That is, the sun protection strip 216 does not affect the photovoltaic light collection of the photovoltaic panels 25. The sun protection strip 216 covering the top of the power bank 11 can prevent the sun from shining on the power bank 11. Through the physical sun protection and heat insulation of the sun protection strip 216 and the heat dissipation and cooling of the heat dissipation holes 217, the power bank 11 can be insulated and cooled to prevent it from overheating under direct sunlight.

[0044] When the power bank 11 no longer needs solar charging, i.e., when the support adjustment assembly needs to be reset, the user unplugs the two-in-one power cord 27 from the two rotating plates 24 and the power bank 11, and retracts the three photovoltaic panels 25 on the same rotating plate 24. After that, the user pulls the two sliders 22 out of the two slot blocks 1 21, thereby removing the multiple photovoltaic panels 25 from the power bank 11. The user also pulls out the two sun protection strips 216 from the two slot blocks 214, thereby removing the sun protection strips 216 from the two rotating plates 24. At this time, the reset of the support adjustment assembly is completed.

[0045] In summary, by supporting the operation of the adjustment components, the following beneficial effects can be achieved: Firstly: Due to portability requirements, existing products have fixed and small photovoltaic panels with an area of ​​25mm, resulting in insufficient power generation capacity.

[0046] By supporting the operation of the adjustment components, a photovoltaic module that can be freely disassembled and folded is designed. When not in use, it can be stored to ensure portability. When in use, it can be folded and extended to greatly expand the light-receiving area, which solves the limitation of fixed area light-receiving in traditional technology, increases the amount of solar energy absorbed per unit time, and improves the efficiency of photovoltaic power supply for charging mobile power supply 11.

[0047] Secondly: The existing fixed photovoltaic panels 25 cannot adjust their angle according to the sun's position, and a large amount of sunlight is not effectively utilized due to the poor incident angle.

[0048] By supporting the operation of the adjustment components, the photovoltaic modules on both sides of the power bank 11 can rotate freely relative to the power bank 11. With the angle adjustment and locking functions of the adjustment components, users can freely adjust and lock the angle of the photovoltaic modules according to the position of the sun, ensuring that the photovoltaic panel 25 is always facing the sun at the optimal angle, minimizing sunlight waste and improving energy conversion efficiency.

[0049] Thirdly: Existing products are prone to overheating due to poor heat dissipation under strong light, which accelerates aging and poses safety risks.

[0050] By supporting the operation of the adjustment components, the design of the sun protection band 216 for physical sun protection and heat insulation, and the heat dissipation holes 217 for heat dissipation and cooling, can provide heat insulation and cooling for the power bank 11, preventing the power bank 11 from overheating under direct sunlight.

[0051] Furthermore, by supporting the operation of the adjustment components, a detachable photovoltaic module and a detachable cooling function are designed. When the photovoltaic module is not in use, the module and cooling structure can be disassembled, making the power bank 11 compact and portable. When in use, the adjustment components can be installed for heat insulation charging, taking into account both the needs of daily portability and efficient power generation.
