The power bank adds a heat sink between the battery and the outer shell to dissipate heat through the heat sink, thereby avoiding the high temperature of the built-in battery, thereby extending the service life and safety of the device. The power bank adopts a cylindrical design, which is easy to carry and has a better grip.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a round power bank with a built-in heat sink, which includes a protective shell 7, the inner cavity of the protective shell 7 is provided with a heat sink 6, the inner side of the heat sink 6 is provided with a built-in battery 4, a control mainboard 3 is installed at one end of the built-in battery 4, a side ventilation groove 604 is opened on the side of the heat sink 6, a buffer pad 601 and a lifting pillar 603 are installed on the top of the heat sink 6, and a connecting through hole 602 is opened in the middle of the top of the heat sink 6.

[0007] Furthermore, the outer wall of the heat dissipation plate 6 is in contact with the outer wall of the protective shell 7 .

[0008] Furthermore, a protective bottom plate 5 is installed at the bottom of the protective shell 7, and a protective top cover 2 is bolted to the top of the protective shell 7.

[0009] Furthermore, a shielding panel 1 is provided on the top of the protective top cover 2 .

[0010] Furthermore, the control main board 3 is equipped with control buttons 31 for user control and operation, a connection port 32 for connecting electronic devices and charging, a lighting lamp 33 for increasing the lighting effect of the device, and a status display screen 34 for staff to check the device status.

[0011] Furthermore, at least two side ventilation grooves 604 are provided and are distributed below the side of the heat sink 6 .

[0012] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: the power bank adds a heat sink between the battery and the shell, and the heat dissipation is performed through the heat sink to avoid the high temperature of the built-in battery, thereby extending the service life and safety of the device; and the power bank adopts a cylindrical design, which is easy to carry and has a better grip.

DETAILED DESCRIPTION

[0020] See also Figure 1-Figure 5 As shown, the technical solution adopted in this specific embodiment is: it includes a protective shell 7, the inner cavity of the protective shell 7 is provided with a heat sink 6, the inner side of the heat sink 6 is provided with a built-in battery 4, one end of the built-in battery 4 is installed with a control main board 3, the side of the heat sink 6 is provided with a side ventilation groove 604, the top of the heat sink 6 is installed with a buffer pad 601 and a lifting pillar 603, and the middle of the top of the heat sink 6 is provided with a connecting through hole 602.

[0021] More specifically, the outer wall of the heat sink 6 is in close contact with the outer wall of the protective housing 7. The heat sink 6 is closely contacted with the protective housing 7 to ensure the conduction of heat and increase the heat dissipation efficiency of the device.

[0022] More specifically, a protective bottom plate 5 is installed at the bottom of the protective housing 7, and a protective top cover 2 is bolted to the top of the protective housing 7. The protective top cover 2, the protective bottom plate 5 and the protective housing 7 can well protect the control mainboard 3 and the built-in battery 4 therein, thereby extending the service life of the entire device.

[0023] More specifically, a shielding panel 1 is provided on the top of the protective top cover 2. The shielding panel 1 can shield the screw holes on the protective top cover 2, and can appropriately add certain patterns, thereby increasing the aesthetics of the device.

[0024] More specifically, the control main board 3 is equipped with control buttons 31 for user control and operation, a connection port 32 for connecting electronic devices and charging, a lighting lamp 33 for increasing the lighting effect of the device, and a status display screen 34 for the staff to check the device status.

[0025] More specifically, at least two side ventilation grooves 604 are provided, and are distributed below the side of the heat sink 6. The side ventilation grooves 604 can ensure the spacing between the built-in battery 4 and the protective shell 7, which can facilitate the circulation of air, thereby ensuring the cooling and heat dissipation effect of the built-in battery 4.

[0026] The working principle of the utility model is as follows: when in use, the user only needs to plug the connecting line into the connecting port 32, and the device will automatically charge its electronic device. When the device is charging and discharging, its built-in battery 4 will generate a certain amount of heat. At this time, the heat sink 6 can absorb the heat in time and dissipate the heat through the protective shell 7, and the buffer pad 601 can lift the control mainboard 3 to avoid the control mainboard 3 being directly connected to the heat sink 6, and the connecting through hole 602 is convenient for connecting the control mainboard 3 with the built-in battery 4. The protective top cover 2 is supported and installed by the lifting pillar 603, so as to facilitate the installation and use of the control mainboard 3, and the heat dissipation and cooling capacity of the built-in battery 4 is further increased by the side ventilation groove 604. Among them, the user can turn on the lighting lamp 33 through the control button 31, and the light source is provided by the lighting lamp 33.

[0027] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
