[0001] The present invention relates to the technical field of solar mobile power sources, and in particular to a mobile power source with a solar panel. Background Art

[0002] Mobile power supplies are often used in activities such as camping, hiking, and self-driving tours to power electrical equipment. Mobile power supplies are mainly composed of a shell, a battery pack, a charging management module, a discharge management module, and a solar panel. The battery pack is used to store electrical energy. The charging management module is used to manage the battery charging, control the charging current and charging voltage, and prevent the battery pack from overcharging. The discharge management module is used to control the output of electrical energy, stabilize the output voltage and current, and meet the needs of different loads. After being exposed to sunlight, the solar panel converts solar energy into electrical energy to charge the battery pack.

[0003] After searching, a Chinese patent with authorization announcement number CN220234567U discloses a solar mobile power supply, including a mobile power supply body, a rubber insulation layer is arranged on the top of the mobile power supply body, a mounting plate is arranged on the top of the rubber insulation layer, a protective frame is installed on the top of the mounting plate, a protruding mechanism is arranged on the protective frame, a mounting frame is arranged on the protruding mechanism, and a solar panel is installed inside the mounting frame.

[0007] Preferably, a heat conducting plate is fixed to the bottom of the heat dissipation plate, 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 the inclined surface is connected to the curved surface, and the bottom of the vertical rod is provided with an inclined portion 1 and a raised portion connected in sequence, the inclined portion 1 is fitted with the inclined surface, and the spring piece is clamped at the bottom of the raised portion.

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

[0010] Preferably, a guide surface curving upward is provided on the top of the inner wall of the circular groove.

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

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

[0013] Preferably, the heat dissipation fin 1 and the heat dissipation fin 2 are both inclined, the horizontal plane where the outer wall of heat dissipation fin 1 is located is above the horizontal plane where the inner wall of heat dissipation fin 1 is located, and the horizontal plane where the inner wall of heat dissipation fin 2 is located is above the horizontal plane where the outer wall of heat dissipation fin 2 is located.

[0014] Preferably, a plurality of inclined grooves are provided on the top of the heat dissipating fin 2, and a plurality of inclined portions 2 are provided on the bottom of the heat dissipating fin 2. The angle between the side of the inclined portion 2 away from the hollow heat dissipating column and the bottom of the heat dissipating fin 2 is an acute angle, and the side of the inclined portion 2 away from the hollow heat dissipating column and the side of the inner wall of the inclined groove close to the hollow heat dissipating column are in the same inclined plane.

[0015] Preferably, four shutters are installed on the four sides of the bracket, and connecting ropes are fixed to the tops of the blades of the shutters close to the solar panel, and one end of the connecting rope away from the shutter 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 provided to adjust the angle of the solar panel so that the solar panel is tilted. The tilted solar panel can reduce the reflection of sunlight, thereby reducing the reflection loss of sunlight, allowing more light energy to enter the solar panel to be absorbed and converted, thereby significantly improving the power generation capacity of the solar panel.

[0017] Through the setting of the heat dissipation mechanism, after the angle of the solar panel is adjusted, the vertical rod extends upward from the hollow heat dissipation column, and the vertical rod is used to increase the contact area between the heat dissipation mechanism and the air, thereby effectively improving the heat exchange capacity between the heat dissipation mechanism and the air and protecting the battery pack from overheating damage.

[0018] By setting the inclined portion 1 and the raised portion, after the vertical rod extends out from the hollow heat dissipation column, the inclined portion 1 of the vertical rod is tightly fitted with the inclined surface in the hollow heat dissipation column, and the raised portion is tightly fitted with the curved surface, thereby enhancing the heat conduction capacity between the hollow heat dissipation column and the vertical rod, preventing heat from accumulating in 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 raised portion is tightly fitted with the curved surface, the vertical rod cannot continue to move upward, thereby preventing the vertical rod from being pulled out of the hollow heat dissipation column.

[0019] By setting the heat dissipation fin 1, heat dissipation fin 2 and vertical grooves, heat dissipation fin 1 and heat dissipation fin 2 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 circulate air inside and outside the hollow heat dissipation column to prevent 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] Through the arrangement of the inclined groove and the inclined portion 2, the heat generated by the heat sink heats the air at its position, thereby generating hot air. During the rising process of the hot air, it flows along the bottom of the heat sink fin 2 to the inclined groove and passes through the inclined groove. The inclined groove reduces the obstruction of the heat sink fin 2 to the rising process of the hot air, and when the hot air flows along the bottom of the heat sink fin 2, the flow of the hot air is guided by the inclined portion 2, so that the hot air can enter the inclined groove more easily. Secondly, when the air flow flows between the heat sink fin 1 and the heat sink fin 2, the pressure between the heat sink fin 1 and the heat sink fin 2 is reduced, and the pressure at the bottom of the heat sink fin 2 is greater than the pressure between the heat sink fin 1 and the heat sink fin 2. At this time, the pressure difference is used to make it easier for the hot air to pass through the inclined groove, 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 setting the shutters and connecting ropes, during the process of adjusting the angle of the solar panel, the opening and closing states of the shutters are automatically adjusted by utilizing the cooperation of the connecting ropes and the shutters, allowing external airflow to enter the heat dissipation mechanism to assist in heat dissipation. When the solar panel is in a horizontal state, the blocked state of the shutter blades effectively prevents external dust from entering the heat dissipation mechanism, thereby protecting the heat dissipation mechanism. The above design simplifies the operation and is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

Airflow flows through the hollow heat dissipation columns 14 from any direction. The hollow heat dissipation columns 14 that are evenly spaced and cylindrical are used to reduce the obstruction to the airflow, so that the airflow flows more smoothly at the hollow heat dissipation columns 14, thereby improving the heat exchange capacity between the heat dissipation mechanism 11 and the airflow, thereby facilitating the heat dissipation of the battery pack 9; The angle adjustment mechanism 3 includes a connecting frame 4 arranged above the hollow heat dissipation column 14, a bracket 8 is fixed on the top of the mobile power supply body 1, and the solar panel 2 is hinged on the top of the bracket 8.

The solar panel 2 is rotated to a tilted state. The tilted solar panel 2 can reduce the reflection of sunlight, thereby reducing the reflection loss of sunlight, allowing more light energy to enter the solar panel 2 to be absorbed and converted, thereby improving the power generation capacity of the solar panel 2.

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

[0029] like Fig. 9 As shown, in the present embodiment, the inner wall of the hollow heat dissipation column 14 is respectively provided with an inclined surface 17 and a curved surface 18 near the top, the inclined surface 17 is located above the curved surface 18, and the inclined surface 17 is connected to the curved surface 18, and the bottom of the vertical rod 6 is provided with an inclined portion 19 and a raised portion 20 connected in sequence, the inclined portion 19 is fitted with the inclined surface 17, and the spring piece 7 is clamped at the bottom of the raised portion 20. When the vertical rod 6 extends upward from the hollow heat dissipation column 14, the inclined portion 19 of the vertical rod 6 is tightly fitted with the inclined surface 17 in the hollow heat dissipation column 14, and the raised portion 20 of the vertical rod 6 is tightly fitted with the curved surface 18, thereby 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 the present embodiment, a circular groove 21 is provided at the bottom of the raised portion 20, 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 with the through groove 22, a through hole 29 is provided at the top of the heat sink 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 sink 13 through the heat conducting plate 12, the heat inside the heat sink 13 passes through the inside of the hollow heat dissipation column 14, the circular groove 21 and the through groove 22 from the through hole 29 in turn, and is finally discharged from the heat dissipation hole 23 of the connecting frame 4, thereby preventing heat from accumulating in the heat sink 13, which helps to improve the heat dissipation capacity of the heat sink 13.

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

[0032] like Figure 3 , Figure 7 , Figure 8 and Fig. 9 As shown, in this embodiment, the outer wall of the hollow heat dissipation column 14 is provided with a plurality of vertical grooves 26, and the vertical grooves 26 are provided on the hollow heat dissipation column 14 for circulating air inside and outside the hollow heat dissipation column 14 to prevent heat from accumulating inside the hollow heat dissipation column 14, thereby improving the heat dissipation capacity of the hollow heat dissipation column 14.

[0033] like Figure 3 , Figure 7 , Figure 8 and Fig. 9 As shown, in the present embodiment, a heat sink 15 is sleeved on the top position of the inner wall of the vertical groove 26 corresponding to the outer wall of the hollow heat sink 14, and a heat sink 16 is sleeved on the bottom position of the inner wall of the vertical groove 26 corresponding to the outer wall of the hollow heat sink 14. The heat sink 15 and the heat sink 16 are used to increase the contact area between the hollow heat sink 14 and the air, thereby improving the heat dissipation capacity of the hollow heat sink 14.

[0034] like Figure 3 , Figure 7 , Figure 8 and Fig. 9As shown, in the present embodiment, the heat dissipation fin 15 and the heat dissipation fin 2 16 are both inclined, the horizontal plane where the outer wall of the heat dissipation fin 15 is located is located above the horizontal plane where the inner wall of the heat dissipation fin 15 is located, and the horizontal plane where the inner wall of the heat dissipation fin 2 16 is located is located above the horizontal plane where the outer wall of the heat dissipation fin 2 16 is located, and the inclined heat dissipation fin 15 and the inclined heat dissipation fin 2 16 are used to guide and gather the airflow passing through, so that the airflow can flow through the vertical groove 26 more smoothly, thereby 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 Fig. 9 As shown, in this embodiment, a plurality of inclined grooves 24 are provided on the top of the second heat sink fin 16, and a plurality of inclined portions 25 are provided on the bottom of the second heat sink fin 16. The angle between the side of the second inclined portion 25 away from the hollow heat sink column 14 and the bottom of the second heat sink fin 16 is an acute angle. The side of the second inclined portion 25 away from the hollow heat sink column 14 and the side of the inner wall of the inclined groove 24 close to the hollow heat sink column 14 are in the same inclined plane. The heat generated by the heat sink 13 heats the air at its position, thereby generating hot air. During the rising process, the hot air flows along the bottom of the second heat sink fin 16 to the inclined groove 24, and passes through the inclined groove 24, thereby reducing the heat dissipation of the second heat sink fin 16 on the heat. The air is blocked during its rising process. When the hot air flows along the bottom of the second heat sink fin 16, the flow of the hot air is guided by the design of the second inclined portion 25, so that the hot air can enter the inclined groove 24 more easily. Secondly, when the airflow flows between the first heat sink fin 15 and the second heat sink fin 16, the pressure between the first heat sink fin 15 and the second heat sink fin 16 is reduced, and the pressure at the bottom of the second heat sink fin 16 is greater than the pressure between the first heat sink fin 15 and the second heat sink fin 16. At this time, the pressure difference is used to make it easier for the hot air to pass through the inclined groove 24, thereby reducing the accumulation of hot air above the heat sink 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 the present embodiment, four shutters 27 are installed on the four sides of the bracket 8, and a connecting rope 28 is fixed on the top of the blade of the shutter 27 close to the solar panel 2, and the end of the connecting rope 28 away from the shutter 27 is fixedly connected to the side of the connecting frame 4, and the four shutters 27 correspond to the four side positions of the bracket 8 respectively, so as to realize the opening and closing of the four sides of the bracket 8, and the connecting frame 4 drives the blades of the shutter 27 to change from the inclined blocking state to the horizontal opening state through the connecting rope 28, at this time, the external airflow can enter the heat dissipation mechanism 11 position from the shutter 27, and when the solar panel 2 is in a horizontal state, the connecting frame 4 no longer drives the connecting rope 28 to pull the blades of the shutter 27, and at this time, the blades of the shutter 27 are in an inclined blocking state. When in the blocking state, it is difficult for external dust to enter the heat dissipation mechanism 11, thereby realizing the protection of the heat dissipation mechanism 11, and at the same time, there is no need to use additional actions to drive the blades of the shutter 27 to flip, the operation is simple, and the use is more convenient.

[0037] Working principle: Hold the right side of the solar panel 2 and flip the solar panel 2 upward. During the upward rotation of the solar panel 2 through the hinge, the connecting frame 4 is driven to move upward through the connecting rod 5. The connecting frame 4 drives the vertical rod 6 to move upward along the inner wall of the hollow heat dissipation column 14. During the upward movement of the vertical rod 6, the protrusion 20 is driven to squeeze the spring piece 7 to deform the spring piece 7. When the inclined portion 19 of the vertical rod 6 is tightly fitted with the inclined surface 17 in the hollow heat dissipation column 14 and the protrusion 20 is tightly fitted with the curved surface 18, the vertical rod 6 stops moving upward, and the angle of the solar panel 2 is rotated to the maximum state. At this time, the protrusion 20 moves to the top of the spring piece 7, and the spring piece 7 is deformed. Under the action of the elastic force of the body, the convex part 20 is restored to the undeformed state, thereby locking the convex part 20 to prevent the convex part 20 from moving downward, thereby realizing the positioning of the angle of the solar panel 2, making the solar panel 2 inclined, and the inclined solar panel 2 can reduce the reflection of sunlight, thereby reducing the reflection loss of sunlight, allowing more light energy to enter the solar panel 2 to be absorbed and converted, and thus improving the power generation capacity of the solar panel 2. At the same time, after the vertical rod 6 is extended upward from the hollow heat dissipation column 14, the vertical rod 6 is used to increase 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 top blades of the shutter 27 are pulled by the connecting rope 28, so that the blades of the shutter 27 are changed from the inclined blocking state to the horizontal opening state, and at this time, the external airflow can enter the heat dissipation mechanism 11 to assist the heat dissipation of the heat dissipation mechanism 11; The heat generated during the operation of the battery pack 9 is transferred to the heat sink 13 and the hollow heat sink 14 through the heat conducting plate 12. The heat at the heat sink 13 can be directly dissipated upward and can pass through the inside of the hollow heat sink 14 and the circular groove 21 and the through groove 22 from the through hole 29 in sequence, and finally be discharged from the heat dissipation hole 23 of the connecting frame 4, thereby preventing the heat from accumulating in the heat sink 13, which helps to improve the heat dissipation capacity of the heat sink 13. After the heat enters the hollow heat sink 14, the vertical groove 26 is used to circulate with the air outside the hollow heat sink 14, which is more conducive to the heat dissipation of the heat sink 13. The hollow heat dissipation column 14 is fixed with heat dissipation fins 15 and 16, and the contact area between the hollow heat dissipation column 14 and the air is increased by using the heat dissipation fins 15 and 16, so as to improve the heat dissipation capacity of the hollow heat dissipation column 14. When the airflow flows between the heat dissipation fins 15 and 16, the inclined heat dissipation fins 15 and 16 are used to guide and gather the airflow, so that the airflow can flow more smoothly through the vertical grooves 26, thereby improving the air flow at the vertical grooves 26, and thus improving the heat dissipation capacity at the hollow heat dissipation column 14. During the heat dissipation process of the heat dissipation plate 13, the heat generated by the heat dissipation plate 13 heats the air at its position, thereby generating hot air. The hot air During the rising process, the hot air flows along the bottom of the second heat sink fin 16 and is guided by the second inclined portion 25, so that the hot air can more easily enter the inclined slot 24 and pass through the inclined slot 24. The obstruction of the second heat sink fin 16 to the rising process of the hot air is reduced by the inclined slot 24. At the same time, when the airflow flows between the first heat sink fin 15 and the second heat sink fin 16, the pressure between the first heat sink fin 15 and the second heat sink fin 16 is reduced, and the pressure at the bottom of the second heat sink fin 16 is greater than the pressure between the first heat sink fin 15 and the second heat sink fin 16. At this time, the pressure difference is used to make it easier for the hot air to pass through the inclined slot 24, reducing the accumulation of hot air above the heat sink 13, and further improving the heat dissipation capacity of the heat dissipation mechanism 11 to the battery pack 9. When the solar panel 2 is used, the solar panel 2 is rotated downward, so that the solar panel 2 drives the connecting frame 4 to move downward through the connecting rod 5, and the connecting frame 4 drives the vertical rod 6 to move downward along the inner wall of the hollow heat dissipation column 14. At the same time, the raised portion 20 at the bottom of the vertical rod 6 squeezes the spring piece 7 to deform the spring piece 7. As the vertical rod 6 moves downward, the raised portion 20 of the vertical rod 6 separates from the spring piece 7 and moves to the bottom of the spring piece 7. When the magnet bar 10 at the bottom of the solar panel 2 fits with the top of the bracket 8, the solar panel 2 is in a horizontal state. At this time, the magnetic force of the magnet bar 10 is used to position the solar panel 2 to prevent the solar panel 2 from rotating at will. During the downward movement of the connecting frame 4, the connecting frame 4 no longer drives the connecting rope 28 to pull the blades of the shutter 27. At this time, the blades of the shutter 27 can be transformed from a horizontal open state to an inclined closed state. The closed state of the blades of the shutter 27 can effectively prevent external dust from entering the heat dissipation mechanism 11, thereby protecting the heat dissipation mechanism 11.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
