Description

Exchangeable battery charging device {battery charging device}

The present invention relates to an exchangeable battery charging device that allows charging and exchanging batteries used in electric two-wheeled vehicles.

Generally, batteries used in electric two-wheeled vehicles are configured to be used after charging. In other words, when the battery of an electric two-wheeled vehicle is discharged, additional use is possible by charging the battery in a battery charging device.

Of course, in the related art, two or more batteries are provided so that when one battery is discharged, the electric two-wheeled vehicle can be used continuously by replacing it with another battery that was previously charged in a battery charging device. At this time, the discharged battery is charged in the battery charging device so that it can be reused.

In other words, since the battery charging device can charge two or more batteries at the same time, it can be used by multiple users.

However, the conventional exchangeable battery charging device described above has the disadvantage of being vulnerable to water leakage. In other words, rainwater was bound to leak through the gap between the entrance for installing the battery and the battery pack installed there.

In particular, as the rainwater leaked as described above flows down to the charging part of the battery pack, various problems caused by moisture, such as electric leakage or rust, are additionally caused.

Of course, in order to prevent the rainwater from leaking, the gap between the battery pack and the inlet for installing the battery of the battery charging device can be formed extremely small, or a separate seal material can be used.

However, when managing the above-mentioned tolerance or using a separate seal material, there is an inconvenience in that the battery pack is not smoothly accommodated in the inlet, and there is a problem in that charging is not performed properly due to incorrect insertion of the battery pack.

The receiving housing 300 is located within the main housing 100, and a pass-through hole 301 is formed on the front side and is installed to match the receiving hole 201 formed in the front cover 200.

A charging unit 400 may be provided at the rear of each receiving housing 300. The charging unit 400 may be formed to charge the battery pack 10 by connecting a charging terminal (not shown) of the battery pack 10 accommodated in the housing 300.

The charging unit 400 may be installed at the rear of the housing 300 while being surrounded by the charging case 410.

Meanwhile, as shown in the attached FIG. 4, each accommodating housing 300 may be installed with a gradual downward slope from the front to the rear. This installation structure has the purpose of allowing the relatively heavy battery pack 10 to be installed smoothly by using its own weight when storing the relatively heavy battery pack 10, and when rainwater flows into the housing housing 300, the rainwater flows smoothly to the rear. It is for the purpose of getting down.

In particular, the front of the main housing 100 may be inclined in a shape that protrudes forward toward the bottom, corresponding to the inclination angle of each housing housing 300 described above.

As shown in the attached FIG. 6, the housing 300 may be formed in a box-shaped structure in which the battery pack 10 can be accommodated. For example, the housing 300 is an upper frame 310 that forms the upper surface, a bottom frame 320 that forms the bottom surface, a side frame 330 that forms both sides, and a rear frame 340 that forms the rear surface. It may be formed as a body containing a.

In addition, as shown in the attached FIG. 9, the bottom frame 320 of the housing 300 is formed so that the rear side is open. In other words, moisture flowing along the floor frame 300 is discharged through the open rear surface.

As shown in the attached FIGS. 8 and 10 to 12, the rear frame 340 of the housing 300 has a cut hole 341 for discharging moisture flowing down the rear of the bottom frame 320. can be formed. That is, moisture discharged through the open rear of the bottom frame 320 passes through the cutout hole 341 of the rear frame 340 and flows down to the bottom of the cutout hole 341.

Meanwhile, as shown in the attached FIG. 10, the bottom surface of the charging case 410 may be configured to be installed at a predetermined distance from the bottom frame 320 of the housing housing 300. That is, moisture can flow down through the spaced area between the charging case 410 and the housing 320. Of course, the charging case 410 may be further formed with a cutout 411 that provides an expanded open area for smoother discharge of moisture.

Next, the charging device according to an embodiment of the present invention is configured to include a rainwater tray 500.

As shown in the attached FIGS. 3 to 12, the rainwater tray 500 is located at the bottom of each housing housing 300 and receives moisture falling from the housing housing 300 and guides it to flow backward. .

The rainwater tray 500 may have a peripheral wall 510 and may be formed in a tray shape capable of storing moisture.

Additionally, a discharge hole 501 is formed in the rainwater tray 500. That is, moisture flowing along the rainwater tray 500 can be discharged to the bottom of the rainwater tray 500 through the discharge hole 501.

The discharge hole 501 may be formed at the rear end of the bottom surface of the rainwater tray 500. That is, by forming a discharge hole 501 on the bottom of the rainwater tray 500, moisture discharged through the discharge hole 501 can be discharged directly below the rainwater tray 500. This can prevent moisture discharged through the discharge hole 501 from splashing outside the designated location.

Of course, although not shown, the discharge hole 501 may be formed on at least one of the rear surfaces of the rainwater tray 500 or a corner between the bottom surface and the rear surface.

Meanwhile, at least one inclined guide 520 may be formed on the upper surface of the rainwater tray 500 to guide the flow of moisture. At this time, the inclined guide 520 moves the discharge hole 501 from both sides of the rear side of the rainwater tray 500 so that the flow of moisture gathers toward the discharge hole 501 as it moves toward the rear of the rainwater tray 500. It can be formed slanted to both sides.

Additionally, the rainwater tray 500 may have a left and right width larger than the bottom of the housing 300. As a result, even if water leakage occurs through a joint between the bottom frame 320 and the side frame 330 of the housing 300, the rainwater tray 500 can receive the corresponding moisture.

Additionally, the rainwater tray 500 may be formed to have a longer front-to-back length than the bottom frame 320 of the receiving housing 300. As a result, even if some splashing occurs in the surrounding area in the process of moisture being discharged through the open rear of the bottom frame 320 and into the cut hole 341 of the rear frame 340 or the cut part 411 of the charging case 410, The rainwater tray 500 can receive all of them.

In particular, the tip of the rainwater tray 500 is installed to be positioned further forward than the coupling portion between the front cover 200 and the receiving housing 300. As a result, even if rainwater flows down through the gap existing at the joint between the front cover 200 and the receiving housing 300, the rainwater can be contained in the rainwater tray 500.

Meanwhile, a support frame 600 may be provided at the bottom of the rainwater tray 500. At this time, the support frame 600 is fixedly installed on the main housing 100, and the rainwater tray 500 is installed to rest on the upper surface of the support tray 600.

Next, the charging device according to an embodiment of the present invention is configured to include a collection duct 700.

The collection duct 700 is configured to collect moisture falling through the discharge hole 501 of the rainwater tray 500 and discharge it to the discharge hose 710.

This collection duct 700 may be located directly below the discharge hole 501 at the bottom of the rainwater tray 500. Preferably, the collection duct 700 may be installed on the support tray 500. For example, the collection duct 700 may be installed to penetrate up and down the support tray 500.

In addition, as shown in the attached FIGS. 9 and 12, the collection duct 700 may be formed in a funnel shape with an inlet wider than the discharge hole 501 and an outlet narrower than the discharge hole 501. At this time, each discharge hose 710 may be connected to the outlet of each collection duct 700.

Meanwhile, as shown in the attached FIGS. 2 and 13, each of the discharge hoses 710 may be connected to be exposed to the bottom of the main housing 100 through one of the bottoms of the main housing 100. In particular, one end of each discharge hose 710 is individually connected to each collection duct 700 installed in each rainwater tray 500, and the other end of each discharge hose 710 is connected to the bottom of the main housing 100. It is connected to be located collectively in one of the locations. This allows the discharge location of moisture to be limited to a single location.

In the following, the operation of the exchangeable battery charging device according to the above-described embodiment of the present invention will be described in more detail.

First, when it is desired to charge the battery pack 10, the battery pack 10 is stored in the storage hole 201 where the empty housing housing 300 is located. If there is no empty space, the fully charged battery pack 10 is taken out, and the battery pack 10 to be charged is stored in the housing 300 from which the battery pack 10 was taken out.

Considering that the housing 300 is installed with a downward slope toward the rear, the battery pack 10 can be accurately inserted until it is connected to the charging unit 400 by simply inserting and installing it.

Then, when the battery pack 10 is inserted, an operation for charging the battery pack 10 is performed through the operation unit 102. Accordingly, charging of the battery pack 10 begins.

While charging of the battery pack 10 is being performed, the charging status may be displayed through the manipulation unit 102. Of course, when charging is completed, charging completion may be announced through the manipulation unit 102.

Meanwhile, since the exchangeable battery charging device according to an embodiment of the present invention is provided outdoors, when it rains or snows, or when condensate forms due to a temperature difference inside and outside the main housing 100, moisture such as rainwater or condensate is present. It can penetrate into the main housing (100).

In particular, since the storage hole 201 of each front cover 200 provided in the main housing 100 is exposed to the outside, a large amount of moisture can penetrate into the housing 300 through the storage hole 201. You can.

Moisture that has penetrated as described above may flow down to the floor frame 320 within the housing 300. At this time, considering that the accommodating housing 300 is installed with a downward slope toward the rear, moisture flowing down to the floor frame 320 within the accommodating housing 300 flows rearward.

Continuing, the moisture passes through the open rear of the floor frame 320 and flows down to the bottom through a gap provided between the connection portion with the rear frame 340. In particular, considering that the cut hole 341 is formed in the rear frame 340, the moisture passes through the cut hole 341 and falls to the bottom of the cut hole 341.

In addition, moisture that falls from the receiving housing 300 is contained in the rainwater tray 500 located at the bottom of the receiving housing 300. That is, the moisture that falls from the rear of the housing 300 and the moisture that falls through the gap existing at the connection between the front cover 200 and the housing 300 are contained in the rainwater tray 500 at the bottom. .

Thereafter, the moisture flows backward due to the inclination of the rainwater tray 500 and then falls into the collection duct 700 while being discharged through the discharge hole 501 formed at the rear end of the rainwater tray 500.

In addition, the moisture that falls into the collection duct 700 flows down to the bottom of the main housing 100 under the guidance of the discharge hose 710 connected to the collection duct 700.

As described above, the exchangeable battery charging device of the present invention can prevent the moisture from flowing into the charging unit 400 even if moisture flows into the housing housing 300, thereby preventing malfunction or malfunction due to electrical leakage of the charging unit 400. Damage to the charging part can be prevented.

In addition, the exchangeable battery charging device of the present invention has an inclined structure of each accommodating housing 300, so that even if moisture penetrates into the accommodating housing 300, it does not accumulate in a specific area, but flows smoothly to the designed location, leaving the outside of the accommodating housing 300. can be discharged as

In addition, the exchangeable battery charging device of the present invention is configured to minimize the phenomenon of splashing to the surroundings during the sequential discharge of moisture, thereby preventing damage to various circuit components in the main housing 300 due to moisture.
