Description

power bank

[0001] The present invention relates to a power bank.

[0002] A charger is a device used to charge a battery.

[0003] An example of a charger may be an electric vehicle charger that charges a vehicle such as an electric vehicle, and electrical energy is supplied to the battery of the electric vehicle by connecting a connector provided at the end of a charging cable to a connection inlet installed in the electric vehicle.

[0004] The charger includes a power module to which a charging cable is connected and a charger body that forms a space in which the power module is accommodated. To use the charging cable, the coiled charging cable is unwound and pulled out, and then the charging connector is inserted into the inlet of the electric vehicle.

[0005] Chargers can be divided into separate chargers and integrated chargers depending on whether the power module and charging cable are installed in one device.

[0006] A detachable charger may include a power bank having a power unit installed therein, and a dispenser having a charging connector connected to the power bank by a charging cable and connected / disconnected to a vehicle by the charging cable.

[0007] An integrated charger may include a power unit, a charging cable connected to the power unit, and a charging connector installed at one end of the charging cable and connected / disconnected from the vehicle, and the power unit and the charging cable may be provided in one device.

[0015] The top seal may include an upper cover portion covering the lower fold portion; a lower cover portion covering the upper fold portion; and a connecting portion connecting an end of the upper cover portion and an end of the lower cover portion.

[0016] The power bank may further include a fixing bracket for fixing the main pole to the base.

[0017] The fixed bracket may include an upper bracket fixed to the main pole; and a lower bracket bent from the upper bracket and fixed to the base.

[0018] The upper bracket may include a first upper bracket fixed to one side of the main pole, and a second upper bracket bent from the first upper bracket and fixed to the other side of the main pole.

[0019] The lower bracket may include a first lower bracket bent from the first upper bracket, and a second lower bracket bent from the second upper bracket and spaced apart from the first lower bracket.

[0020] Multiple main poles can be erected on the base.

[0021] The power bank may further include a lower inner support positioned between a pair of adjacent main poles among the plurality of main poles.

[0022] A lower bending portion may be bent at the bottom of at least one of the side main will and the cover main will. The lower bending portion may be positioned between the upper surface of the base and the lower surface of the lower inner support.

[0023] The power bank may further include a lower rubber cap positioned at the end of the lower inner support.

[0024] The power bank may further include a lower seal disposed between the upper surface of the base and the lower surface of the lower inner support.

[0025] The lower ceiling is parallel to the lower bend and can seal between the upper surface of the base and the lower surface of the lower inner support.

[0026] According to this embodiment, the multi-stage bending portion folded on the side main wall surrounds the main pole, and the inner sealing seals between the multi-stage bending portion of the side main wall and the side bending portion of the cover main wall, so that the assembly structure can be simplified and the sealing capacity can be improved.

[0027] Additionally, the upper rubber cap fitted on the top of the main pole can minimize the penetration of rainwater, etc. into the interior of the main pole.

[0028] In addition, the space between the upper fold formed on the top of at least one of the side main wall and the cover main wall and the lower fold formed on the top body is sealed by the top seal, thereby minimizing the infiltration of rainwater, etc. into the space formed by the side main wall and the cover main wall.

[0029] Additionally, the fixed bracket can secure multiple sides of the main pole to the base, minimizing the number of parts and more reliably securing the main pole to the base.

[0030] In addition, a lower bend portion bent at the bottom of at least one of the side main will and the cover main will is arranged between the upper surface of the base and the lower surface of the lower inner support, so that the penetration of rainwater, etc. can be minimized with a simple structure.

[0031] Additionally, the waterproofing capability can be further improved by including a lower seal placed between the upper surface of the base and the lower surface of the lower inner support.
