Description

Technical Field

[0001] This invention relates to the field of solar-powered mobile power supply technology, and in particular to a mobile power supply with a solar panel. Background Technology

[0002] Portable power banks are commonly used in activities such as camping, hiking, and road trips to power electrical devices. A portable power bank mainly consists of a casing, a battery pack, a charging management module, a discharging management module, and a solar panel. The battery pack stores electrical energy, the charging management module manages the charging of the battery, controls the charging current and voltage to prevent overcharging, and the discharging management module controls the output of electrical energy, stabilizing the output voltage and current to meet the needs of different loads. The solar panel converts solar energy into electrical energy after being exposed to sunlight, thus charging the battery pack.

[0003] A search revealed that Chinese patent CN220234567U discloses a solar-powered portable power bank, comprising a portable power bank body, a rubber heat insulation layer on the top of the portable power bank body, a mounting plate on the top of the rubber heat insulation layer, a protective frame on the top of the mounting plate, a protruding mechanism on the protective frame, a mounting frame on the protruding mechanism, and a solar panel installed inside the mounting frame.

[0004] The aforementioned patent increases the space between the solar panel and the power bank by moving the solar panel upwards, preventing the heat generated by the solar panel from affecting the power bank. However, after the solar panel is raised, it remains in a horizontal position. When sunlight shines on the horizontal solar panel, the reflection loss of sunlight is significant, thus affecting the power generation of the solar panel. Therefore, this application provides a power bank with a solar panel to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a mobile power supply with a solar panel to solve the problem that when sunlight shines on a horizontally positioned solar panel, the reflection loss of sunlight is large, which affects the power generation of the solar panel.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A portable power bank with a solar panel includes a power bank body, a solar panel, and a battery pack installed inside the power bank body. The solar panel and the battery pack are electrically connected. The power bank also includes: The heat dissipation mechanism includes a heat dissipation plate disposed above the battery pack, and a plurality of hollow heat dissipation columns are fixed on the heat dissipation plate. The heat dissipation plate and the hollow heat dissipation columns are used for heat dissipation of the battery pack. The angle adjustment mechanism includes a connecting frame set above the hollow heat dissipation column, a bracket fixed to the top of the power bank body, a solar panel hinged to the top of the bracket, the connecting frame located inside the bracket, a connecting rod rotatably connecting the connecting frame and the solar panel, a vertical rod fixed to the bottom of the connecting frame, the vertical rod slidingly connected to the inner wall of the hollow heat dissipation column, and at least two spring clips fixed to the inner wall of the hollow heat dissipation column, the spring clips snapping into the bottom of the vertical rod, and a magnetic strip embedded in the bottom of the solar panel; Rotating the solar panel upwards causes the connecting frame to move upwards via a linkage. The connecting frame then moves the vertical rod upwards along the inner wall of the hollow heat dissipation column and is held in place by a spring clip, thus achieving the positioning of the solar panel after angle adjustment.

[0007] Preferably, a heat-conducting plate is fixed to the bottom of the heat sink, and the heat-conducting plate is attached to the top of the battery pack.

[0008] Preferably, the inner wall of the hollow heat dissipation column is provided with an inclined surface and a curved surface near the top, the inclined surface is located above the curved surface and is connected to the curved surface, and the bottom of the vertical rod is provided with an inclined part and a protrusion connected in sequence, the inclined part is attached to the inclined surface, and the spring clip is engaged with the bottom of the protrusion.

[0009] Preferably, the bottom of the protrusion is provided with a circular groove, the top of the inner wall of the circular groove is provided with a through groove, the diameter of the circular groove is larger than the diameter of the through groove, the top of the connecting frame is provided with a heat dissipation hole, the heat dissipation hole is connected to the through groove, and the top of the heat dissipation plate is provided with a through hole corresponding to the position of the hollow heat dissipation column.

[0010] Preferably, the top of the inner wall of the circular groove is provided with an upwardly curved guide surface.

[0011] Preferably, the outer wall of the hollow heat dissipation column is provided with a plurality of vertical grooves.

[0012] Preferably, a heat dissipation fin one is sleeved on the outer wall of the hollow heat dissipation column at the top position corresponding to the inner wall of the vertical groove, and a heat dissipation fin two is sleeved on the outer wall of the hollow heat dissipation column at the bottom position corresponding to the inner wall of the vertical groove.

[0013] Preferably, both the first heat dissipation fin and the second heat dissipation fin are inclined, with the horizontal plane of the outer wall of the first heat dissipation fin located above the horizontal plane of the inner wall of the first heat dissipation fin, and the horizontal plane of the inner wall of the second heat dissipation fin located above the horizontal plane of the outer wall of the second heat dissipation fin.

[0014] Preferably, the top of the second heat dissipation fin has several inclined grooves, and the bottom of the second heat dissipation fin has several inclined portions. The angle between the side of the inclined portion away from the hollow heat dissipation column and the bottom of the second heat dissipation fin is an acute angle. The side of the inclined portion away from the hollow heat dissipation column and the side of the inner wall of the inclined groove close to the hollow heat dissipation column are in the same inclined plane.

[0015] Preferably, four louvers are installed on each of the four sides of the bracket. A connecting rope is fixed to the top of the blades of the louvers near the solar panel, and the end of the connecting rope away from the louvers is fixedly connected to the side of the connecting frame.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, the angle adjustment mechanism is used to adjust the angle of the solar panel, making the solar panel tilted. The tilted solar panel can reduce the reflection of sunlight, thereby reducing the loss of sunlight due to reflection, allowing more light energy to enter the interior of the solar panel for absorption and conversion, which significantly improves the power generation capacity of the solar panel.

[0017] By setting up a heat dissipation mechanism, after the angle of the solar panel is adjusted, the vertical rod extends upward from inside the hollow heat dissipation column. The vertical rod increases the contact area between the heat dissipation mechanism and the air, effectively improving the heat exchange capacity between the heat dissipation mechanism and the air, and protecting the battery pack from overheating damage.

[0018] With the addition of the inclined section and the protrusion, after the vertical rod extends out of the hollow heat dissipation column, the inclined section of the vertical rod fits tightly against the inclined surface inside the hollow heat dissipation column, and the protrusion fits tightly against the curved surface. This enhances the heat conduction between the hollow heat dissipation column and the vertical rod, preventing heat from accumulating at the heat dissipation plate and the hollow heat dissipation column, and further improving the heat dissipation efficiency of the battery pack. At the same time, when the protrusion fits tightly against the curved surface, the vertical rod cannot continue to move upward, thus preventing the vertical rod from being pulled out of the hollow heat dissipation column.

[0019] By setting up heat dissipation fins one and two and vertical grooves, heat dissipation fins one and two are used to increase the contact area between the hollow heat dissipation column and the air, thereby improving the heat dissipation capacity of the hollow heat dissipation column. At the same time, the vertical grooves are opened on the hollow heat dissipation column to facilitate the circulation of air inside and outside the hollow heat dissipation column, preventing heat from accumulating inside the hollow heat dissipation column, thereby improving the heat dissipation capacity of the hollow heat dissipation column for the battery pack.

[0020] By using the inclined groove and the second inclined section, the heat generated by the heat sink heats the air at its location, thus producing hot air. As the hot air rises, it flows along the bottom of the second heat sink fin towards the inclined groove and passes through it. The inclined groove reduces the obstruction of the rising hot air by the second heat sink fin. Furthermore, as the hot air flows along the bottom of the second heat sink fin, the second inclined section guides the flow of the hot air, making it easier for the hot air to enter the inclined groove. Secondly, when the airflow passes between the first and second heat sink fins, the pressure between the first and second heat sink fins decreases. The pressure at the bottom of the second heat sink fin is greater than the pressure between the first and second heat sink fins. This pressure difference allows the hot air to pass through the inclined groove more easily, thereby reducing the accumulation of hot air above the heat sink and further improving the heat dissipation capacity of the heat dissipation mechanism for the battery pack.

[0021] By incorporating louvers and connecting ropes, the opening and closing of the louvers are automatically adjusted during solar panel angle adjustment. This allows external airflow to enter the heat dissipation mechanism to assist in heat dissipation. When the solar panel is horizontal, the louver blades effectively prevent external dust from entering the heat dissipation mechanism, thus protecting it. This design simplifies operation and makes it more convenient to use. Attached Figure Description

However, this is only for illustrative purposes and is not intended to limit the present invention to the specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0026] The present invention provides a portable power supply with a solar panel, which will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0027] like Figures 1-9 As shown, an embodiment of the present invention provides a portable power bank with a solar panel, including a portable power bank body 1, a solar panel 2, and a battery pack 9 installed in the portable power bank body 1. The solar panel 2 is electrically connected to the battery pack 9, and the solar panel 2 converts solar energy into electrical energy to charge the battery pack 9. The power bank also includes: The heat dissipation mechanism 11 includes a heat dissipation plate 13 disposed above the battery pack 9. Several hollow heat dissipation columns 14 are fixed on the heat dissipation plate 13. The heat dissipation plate 13 and the hollow heat dissipation columns 14 are used for heat dissipation of the battery pack 9. The several hollow heat dissipation columns 14 are evenly distributed on the heat dissipation plate 13. The hollow heat dissipation columns 14 are cylindrical. Airflow flows through the hollow heat dissipation columns 14 from any direction. The evenly distributed and cylindrical hollow heat dissipation columns 14 reduce the obstruction to the airflow and make the airflow at the hollow heat dissipation columns 14 smoother, thereby improving the heat exchange capacity between the heat dissipation mechanism 11 and the airflow, thus helping to dissipate heat from the battery pack 9. The angle adjustment mechanism 3 includes a connecting frame 4 disposed above the hollow heat dissipation column 14, a bracket 8 fixed on the top of the power supply body 1, a solar panel 2 hinged to the top of the bracket 8, and the solar panel 2 and the bracket 8 connected by a hinge, which allows the solar panel 2 to rotate on the bracket 8. The connecting frame 4 is located inside the bracket 8, and a connecting rod 5 is rotatably connected between the connecting frame 4 and the solar panel 2. The top of the connecting rod 5 is sleeved on the pivot installed at the bottom of the solar panel 2, and the bottom of the connecting rod 5 is sleeved on the pivot installed at the connecting frame 4. The two pivots realize the rotatable connection between the connecting rod 5, the connecting frame 4, and the solar panel 2. A vertical rod 6 is fixed at the bottom of the connecting frame 4, and the vertical rod 6 is slidably connected to the inner wall of the hollow heat dissipation column 14. At least two spring pieces 7 are fixed on the inner wall of the hollow heat dissipation column 14, and the spring pieces 7 are snapped into the bottom of the vertical rod 6. A magnetic strip 10 is embedded in the bottom of the solar panel 2. Rotating the solar panel 2 upwards causes the connecting frame 4 to move upwards via the connecting rod 5. The connecting frame 4 then moves the vertical rod 6 upwards along the inner wall of the hollow heat dissipation column 14 and is held in place by the spring clip 7. This achieves the positioning of the solar panel 2 after angle adjustment. Rotating the solar panel 2 to an inclined state reduces the reflection of sunlight, thereby reducing the loss of sunlight and allowing more light energy to enter the interior of the solar panel 2 for absorption and conversion, thus improving the power generation capacity of the solar panel 2.

[0028] like Figure 2 As shown in this embodiment, a heat-conducting plate 12 is fixed to the bottom of the heat sink 13. The heat-conducting plate 12 is attached to the top of the battery pack 9. The heat-conducting plate 12 is used to improve the heat conduction between the battery pack 9 and the heat sink 13, thereby helping the battery pack 9 to dissipate heat.

[0029] like Figure 9 As shown in this embodiment, the inner wall of the hollow heat dissipation column 14 is provided with a slanted surface 17 and a curved surface 18 near the top. The slanted surface 17 is located above the curved surface 18 and is connected to the curved surface 18. The bottom of the vertical rod 6 is provided with a slanted portion 19 and a protrusion 20 connected in sequence. The slanted portion 19 fits into the slanted surface 17, and the spring piece 7 is engaged with the bottom of the protrusion 20. When the vertical rod 6 extends upward from inside the hollow heat dissipation column 14, the slanted portion 19 of the vertical rod 6 fits tightly into the slanted surface 17 inside the hollow heat dissipation column 14, and the protrusion 20 of the vertical rod 6 fits tightly into the curved surface 18, increasing the heat conduction capacity between the hollow heat dissipation column 14 and the vertical rod 6, preventing heat from accumulating at the hollow heat dissipation column 14, thereby effectively improving the heat exchange capacity between the heat dissipation mechanism 11 and the air, and protecting the battery pack 9 from overheating damage.

[0030] like Figure 3As shown in this embodiment, a circular groove 21 is provided at the bottom of the protrusion 20, and a through groove 22 is provided at the top of the inner wall of the circular groove 21. The diameter of the circular groove 21 is larger than the diameter of the through groove 22. A heat dissipation hole 23 is provided at the top of the connecting frame 4. The heat dissipation hole 23 is connected to the through groove 22. A through hole 29 is provided at the top of the heat dissipation plate 13 corresponding to the position of the hollow heat dissipation column 14. The heat generated during the operation of the battery pack 9 is transferred to the heat dissipation plate 13 through the heat conduction plate 12. The heat inside the heat dissipation plate 13 passes through the through hole 29 in sequence through the interior of the hollow heat dissipation column 14, the circular groove 21, and the through groove 22, and is finally discharged from the heat dissipation hole 23 of the connecting frame 4, thereby preventing heat from accumulating inside the heat dissipation plate 13 and helping to improve the heat dissipation capacity of the heat dissipation plate 13.

[0031] like Figure 3 As shown in this embodiment, the top of the inner wall of the circular groove 21 is provided with an upwardly curved guide surface. The hot air in the hollow heat dissipation column 14 enters the circular groove 21 during its upward movement. The guide surface is used to guide the hot air flowing through, so that the hot air can enter the through groove 22 more smoothly and reduce the accumulation of heat in the circular groove 21.

[0032] like Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown in this embodiment, the outer wall of the hollow heat dissipation column 14 is provided with a number of vertical grooves 26. The vertical grooves 26 are provided on the hollow heat dissipation column 14 to allow air circulation inside and outside the hollow heat dissipation column 14, prevent heat from accumulating inside the hollow heat dissipation column 14, and thus improve the heat dissipation capacity of the hollow heat dissipation column 14.

[0033] like Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown in this embodiment, a heat dissipation fin 15 is fitted onto the top position of the outer wall of the hollow heat dissipation column 14 corresponding to the inner wall of the vertical groove 26, and a heat dissipation fin 26 is fitted onto the bottom position of the outer wall of the hollow heat dissipation column 14 corresponding to the inner wall of the vertical groove 26. The heat dissipation fin 15 and the heat dissipation fin 26 are used to increase the contact area between the hollow heat dissipation column 14 and the air, thereby improving the heat dissipation capacity of the hollow heat dissipation column 14.

[0034] like Figure 3 , Figure 7 , Figure 8 and Figure 9As shown in this embodiment, both heat dissipation fin 15 and heat dissipation fin 2 16 are inclined. The horizontal plane of the outer wall of heat dissipation fin 15 is above the horizontal plane of the inner wall of heat dissipation fin 15, and the horizontal plane of the inner wall of heat dissipation fin 2 16 is above the horizontal plane of the outer wall of heat dissipation fin 2 16. By using the inclined heat dissipation fin 15 and the inclined heat dissipation fin 2 16, the airflow is guided and gathered, so that the airflow flows more smoothly from the vertical groove 26, improving the air flow at the vertical groove 26, thereby improving the heat dissipation capacity of the hollow heat dissipation column 14.

[0035] like Figure 4 and Figure 9 As shown in this embodiment, the top of the second heat dissipation fin 16 is provided with several inclined slots 24, and the bottom of the second heat dissipation fin 16 is provided with several inclined portions 25. The angle between the side of the inclined portion 25 away from the hollow heat dissipation column 14 and the bottom of the second heat dissipation fin 16 is an acute angle. The side of the inclined portion 25 away from the hollow heat dissipation column 14 and the side of the inner wall of the inclined slot 24 near the hollow heat dissipation column 14 are in the same inclined plane. The heat generated by the heat dissipation plate 13 heats the air at its location, thereby generating hot air. As the hot air rises, it flows along the bottom of the second heat dissipation fin 16 to the inclined slot 24 and passes through the inclined slot 24, reducing the heat dissipation fin 16's heat transfer efficiency. During the upward movement of air, the hot air flows along the bottom of the second heat dissipation fin 16. The design of the second inclined part 25 guides the flow of hot air, making it easier for the hot air to enter the inclined groove 24. Secondly, when the airflow passes between the first heat dissipation fin 15 and the second heat dissipation fin 16, the pressure between the first heat dissipation fin 15 and the second heat dissipation fin 16 decreases. The pressure at the bottom of the second heat dissipation fin 16 is greater than the pressure between the first heat dissipation fin 15 and the second heat dissipation fin 16. At this time, the pressure difference makes it easier for the hot air to pass through the inclined groove 24, thereby reducing the accumulation of hot air above the heat dissipation plate 13 and further improving the heat dissipation capacity of the heat dissipation mechanism 11.

[0036] like Figure 1 , Figure 2 and Figure 5As shown in this embodiment, four louvers 27 are installed on each of the four sides of the bracket 8. A connecting rope 28 is fixed to the top of the blades of the louvers 27 near the solar panel 2. The end of the connecting rope 28 away from the louvers 27 is fixedly connected to the side of the connecting frame 4. The four louvers 27 correspond to the four sides of the bracket 8, realizing the opening and closing of the four sides of the bracket 8. When the connecting frame 4 drives the blades of the louvers 27 from the inclined blocked state to the horizontal open state through the connecting rope 28, the outside airflow can enter the heat dissipation mechanism 11 through the louvers 27. When the solar panel 2 is in the horizontal state, the connecting frame 4 no longer drives the connecting rope 28 to pull the blades of the louvers 27. At this time, the blades of the louvers 27 are in the inclined blocked state. When in the blocked state, it is difficult for outside dust to enter the heat dissipation mechanism 11, thereby protecting the heat dissipation mechanism 11. At the same time, there is no need to use additional actions to drive the blades of the louvers 27 to rotate, making the operation simple and more convenient to use.

[0037] Working principle: Hold the right side of solar panel 2 and flip it upwards. As solar panel 2 rotates upwards via the hinge, it drives the connecting frame 4 upwards via the connecting rod 5. The connecting frame 4 drives the vertical rod 6 upwards along the inner wall of the hollow heat dissipation column 14. During the upward movement of the vertical rod 6, the protrusion 20 presses against the spring 7, causing the spring 7 to deform. When the inclined part 19 of the vertical rod 6 is tightly fitted with the inclined contact surface 17 inside the hollow heat dissipation column 14 and the protrusion 20 is tightly fitted with the curved surface 18, the vertical rod 6 stops moving upwards, and the angle of solar panel 2 rotates to its maximum. At this time, the protrusion 20 moves above the spring 7, and the spring 7... Under the action of elastic force, it returns to its undeformed state, thereby locking the protrusion 20 and preventing it from moving downward, thus achieving the positioning of the solar panel 2 at an angle, making the solar panel 2 tilted. The tilted solar panel 2 can reduce the reflection of sunlight, thereby reducing the loss of sunlight reflection and allowing more light energy to enter the interior of the solar panel 2 for absorption and conversion, which can improve the power generation capacity of the solar panel 2. At the same time, after the vertical rod 6 extends upward from the hollow heat dissipation column 14, the vertical rod 6 increases the contact area between the heat dissipation mechanism 11 and the air, effectively improving the heat exchange capacity between the heat dissipation mechanism 11 and the air, and protecting the battery pack 9 from overheating damage. During the upward movement of the connecting frame 4, the topmost blade of the louver 27 is pulled by the connecting rope 28, thereby changing the blade of the louver 27 from an inclined blocked state to a horizontal open state. At this time, the external airflow can assist the heat dissipation mechanism 11 in dissipating heat. The heat generated during the operation of the battery pack 9 is transferred to the heat dissipation plate 13 and the hollow heat dissipation column 14 through the heat conduction plate 12. The heat at the heat dissipation plate 13 can be directly dissipated upwards and pass through the through hole 29 in sequence through the interior of the hollow heat dissipation column 14 and through the circular groove 21 and through groove 22, and finally discharged from the heat dissipation hole 23 of the connecting frame 4, thereby preventing heat from accumulating in the heat dissipation plate 13 and helping to improve the heat dissipation capacity of the heat dissipation plate 13. After the heat enters the hollow heat dissipation column 14, it is circulated with the outside air of the hollow heat dissipation column 14 through the vertical groove 26, which further helps the heat dissipation at the heat dissipation plate 13. The hollow heat dissipation column 14 is fixed with heat dissipation fins 15 and 16. These fins increase the contact area between the hollow heat dissipation column 14 and the air, improving its heat dissipation capacity. When airflow passes between the fins 15 and 16, the inclined fins guide and concentrate the airflow, allowing it to flow more smoothly through the vertical groove 26, thus improving airflow at the groove and further enhancing the heat dissipation capacity of the hollow heat dissipation column 14. During heat dissipation, the heat generated by the heat dissipation plate 13 heats the air at its location, generating hot air. During the upward flow of the air, it flows along the bottom of the second heat dissipation fin 16 and is guided by the second inclined part 25, making it easier for the hot air to enter the inclined groove 24 and pass through the inclined groove 24. The inclined groove 24 reduces the obstruction of the second heat dissipation fin 16 on the upward flow of the hot air. At the same time, when the airflow flows between the first heat dissipation fin 15 and the second heat dissipation fin 16, the pressure between the first heat dissipation fin 15 and the second heat dissipation fin 16 decreases. The pressure at the bottom of the second heat dissipation fin 16 is greater than the pressure between the first heat dissipation fin 15 and the second heat dissipation fin 16. At this time, the pressure difference makes it easier for the hot air to pass through the inclined groove 24, reducing the accumulation of hot air above the heat dissipation plate 13 and further improving the heat dissipation capacity of the heat dissipation mechanism 11 for the battery pack 9. After the solar panel 2 is used, rotate the solar panel 2 downwards. This causes the solar panel 2 to move downwards via the connecting rod 5 and the connecting frame 4. The connecting frame 4 then causes the vertical rod 6 to move downwards along the inner wall of the hollow heat dissipation column 14. At the same time, the protrusion 20 at the bottom of the vertical rod 6 presses the spring 7, causing the spring 7 to deform. As the vertical rod 6 moves downwards, the protrusion 20 separates from the spring 7 and moves to below the spring 7. When the magnetic strip 10 at the bottom of the solar panel 2 is attached to the top of the bracket 8, the solar panel 2 is in a horizontal state. At this time, the magnetic force of the magnetic strip 10 is used to position the solar panel 2, preventing the solar panel 2 from rotating arbitrarily. During the downward movement of the connecting frame 4, the connecting frame 4 no longer drives the connecting rope 28 to pull the slats of the louver 27. At this time, the slats of the louver 27 can change from a horizontal open state to an inclined closed state. The closed state of the louver 27 effectively prevents external dust from entering the heat dissipation mechanism 11, thus protecting the heat dissipation mechanism 11.

[0038] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
