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 via a charging cable and connected / disconnected to a vehicle via 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.

[0008] The present embodiment provides a power bank that can shorten assembly time and is easy to reassemble.

[0009] The present embodiment provides a power bank with improved waterproofing capabilities.

[0010] An example of a power bank according to the present embodiment includes a base; a main pole erected on the base and having an opening formed therein; and a plurality of main walls coupled to the main pole, wherein the plurality of main walls include a side main wall having a first bend formed therein to be inserted and received into the opening and covering a side surface of the main pole; and a cover main wall having a second bend formed therein to be inserted and received into the opening and covering one of the front and rear surfaces of the main pole.

[0011] The opening can be opened in an inclined direction to the main pole.

[0012] The power bank may include a main seal inserted into the opening.

[0013] The main seal can be in contact with the main pole and each of the first and second bends.

[0014] The main sealing may include a first sealing portion that seals between the main pole and the first bending portion; a second sealing portion that seals between the main pole and the second bending portion; and a third sealing portion that connects the first sealing portion and the second sealing portion and seals between the first bending portion and the second bending portion.

[0015] The side main wall may include a side plate forming a side facade.

[0016] The first bend may have an angle of 40° to 50° with the side plate.

[0017] The cover main wall may include a cover plate forming a front facade or a back facade.

[0018] The second bend may have an angle of 40° to 50° with the cover plate.

[0019] Another example of a power bank according to the present embodiment includes a base; a main pole erected on the base and having a first opening and a second opening formed therein; and a plurality of main walls coupled to the main pole,

[0020] The plurality of main walls include a side main wall having a first bend formed therein to be inserted and received into a first opening; and a cover main wall having a second bend formed therein to be inserted and received into a second opening, wherein the first opening and the second opening can be opened in different directions.

[0021] The power bank may further include a first seal inserted into the first opening and in contact with each of the main pole and the first bending portion, and sealing between the main pole and the first bending portion; and a second seal inserted into the second opening and in contact with each of the main pole and the second bending portion, and sealing between the main pole and the second bending portion.

[0022] The main pole may be exposed to the outside on all surfaces except the surface where the first opening is formed and the surface where the second opening is formed.

[0023] An upper bending portion may be formed on each of the side main wall and the cover main wall.

[0024] The power bank may further include a top body having an upper space formed by being mounted on an upper fold and having an open lower surface therein; a top frame accommodated in the upper space; a sealing cover sealing between the upper fold of the side main wall and the upper fold of the cover main wall; and a top seal disposed between the upper fold and the top frame.

[0025] The sealing cover can be placed on the upper fold of the side main wall and the lower surface of the upper fold of the cover main wall.

[0026] The sealing cover may be formed with a protrusion inserted into the gap between the upper fold of the side main wall and the upper fold of the cover main wall.

[0027] A fastening hole may be formed in each of the top cover and the top frame, and the top cover and the top frame may be joined by a fastening member penetrating the fastening hole.

[0028] A fastening hole is formed in each of the top frame and the upper bend portion, and the top frame and the upper bend portion can be joined by a fastening member penetrating the fastening hole.

[0029] Multiple main walls can be spaced apart.

[0030] Lower inner supporters can be placed between adjacent main walls among multiple main walls.

[0031] At least one of the side main wall and the cover main wall may have a lower bend formed between the base and the lower inner support.

[0032] A lower sealing member may be placed on the lower inner supporter to seal the space between the lower bend and the lower inner supporter.

[0033] The main wall may include a main plate forming the exterior.

[0034] The lower bend can be bent at the bottom of the main plate.

[0035] The lower seal can be in contact with each of the main plate and the lower bending section.

[0036] The lower inner supporter may have a receiving groove formed to accommodate the lower sealing insert.

[0037] A fastening hole through which a fastening member passes may be formed in the lower bending portion, and a lower fastening hole through which a fastening member passes may be formed in the base with the fastening holes aligned in the vertical direction.

[0038] According to this embodiment, the side main wall, the cover main wall, and the main pole can be quickly assembled by a simple operation of inserting the first bend of the side main wall and the second bend of the cover main wall into the opening of the main pole.

[0039] Additionally, the main pole is hidden in the side main wall and the cover main wall, which has the advantage of a simple appearance.

[0040] In addition, one main sealing placed in the opening of the main pole can seal between the main pole and the first bend, between the main pole and the second bend, and between the first bend and the second bend, respectively, thereby minimizing the number of parts and facilitating assembly.

[0041] According to this embodiment, the side main wall and the cover main wall can be easily assembled to the main pole by a simple operation of inserting the first bend formed in the side main wall into the first opening of the main pole and inserting the second bend formed in the cover main wall into the second opening of the main pole.

[0042] In addition, since the main pole and the first bend are sealed by the first sealing, and the main pole and the second bend are sealed by the second sealing, the sealing ability can be improved.

[0043] Additionally, the main pole has some of its outer surfaces exposed to the outside, and each of the side main walls and the cover main walls can shield between adjacent multiple main poles.

[0044] In addition, the space between the top cover and the main body can be sealed by the upper bend formed in each of the side main wall and the cover main wall, and the top sealing arranged between the upper bend and the top frame, thereby minimizing rainwater, etc. from seeping into the space of the main body.

[0045] Additionally, the space between the main body and the base can be sealed by a lower bend formed in at least one of the side main wall and the cover main wall and a lower sealing disposed on the lower inner supporter.
