Battery swapping station drainage mechanism

Abstract

This invention provides a drainage mechanism for a battery swapping station, comprising a cabinet frame, a drainage adapter, and a battery compartment. The cabinet frame has inclined shelves, and the rear panel of the shelves has through mounting holes and positioning holes. The drainage adapter is fixed to the rear panel through the mounting holes and includes a receiving part and a pipe connection part disposed on both sides of the rear panel. The pipe connection part connects to a drain pipe and guides it to the bottom of the cabinet frame. The rear end of the battery compartment has a drain hole and a positioning post, corresponding to the receiving part and the positioning hole, respectively. When the battery compartment is assembled from the front of the cabinet frame to the rear panel close to the shelf, the positioning post is inserted into the positioning hole to guide the drain hole and the receiving part to fit tightly together, achieving blind-plug connection of the drainage interface. This simplifies the installation process, shortens the drainage path, improves hydraulic efficiency, and effectively prevents liquid from damaging internal components.

Claims

1. A drainage mechanism for a battery swapping station, comprising: a cabinet frame including a single-layer plate, wherein the single-layer plate is inclined and includes a mounting hole, at least one positioning hole, a bottom plate, and a rear side plate, wherein the rear side plate is connected to the bottom plate, the mounting hole and the at least one positioning hole penetrate the rear side plate and are arranged adjacent to each other; a drainage adapter fixed to the rear side plate of the single-layer plate through the mounting hole, wherein the drainage adapter includes a receiving portion and a pipe connection portion, the receiving portion and the pipe connection portion are respectively located on two opposite sides of the rear side plate, the receiving portion is located above the bottom plate, and the pipe connection portion is assembled with a drainage pipe and guided to the bottom of the cabinet frame; and a battery slot correspondingly disposed on the single-layer plate, wherein the battery slot includes a drainage hole and at least one positioning post disposed at a rear end of the battery slot, the drainage hole and the at least one positioning post are arranged adjacent to each other and are spatially opposite the drainage adapter and the at least one positioning hole respectively; The battery compartment is assembled from the front of the cabinet frame inwards. The rear end of the battery compartment is close to the rear side panel of the shelf. At least one positioning post is inserted into the at least one positioning hole, so that the drain hole and the receiving part of the drain adapter form a tight connection for liquid communication, allowing the liquid in the battery compartment to be discharged through the drain hole and the drain adapter into the drain pipe.

2. The drainage mechanism as claimed in claim 1, wherein the battery compartment further includes a receiving seat and a sealing gasket, spatially relative to the drainage adapter, the receiving seat being disposed around the drainage hole at the rear end of the battery compartment, and the sealing gasket being received in the receiving seat and assembled between the receiving portion of the drainage adapter and the drainage hole of the battery compartment.

3. The drainage mechanism as claimed in claim 2, wherein the receiving seat has an inner guide ramp disposed at the front end, spatially opposite the receiving portion of the drainage adapter, for guiding the receiving portion to abut against the sealing gasket inside the receiving seat when the battery compartment is assembled close to the shelf.

4. The drainage mechanism as claimed in claim 2, wherein the drainage adapter has an outer guide slope disposed at the front end of the receiving part, spatially opposite to the sealing gasket in the receiving seat, for guiding the receiving part to abut against the sealing gasket in the receiving seat when the battery compartment is assembled close to the shelf.

5. The drainage mechanism as claimed in claim 2, wherein an extension length of the at least one positioning post relative to the rear end is greater than an extension length of the receiving portion relative to the rear side plate, and when the battery compartment is inserted into the at least one positioning hole through the at least one positioning post, structural pressure is generated between the rear end of the battery compartment and the receiving portion of the drainage adapter, causing the sealing gasket to be compressed.

6. The drainage mechanism as claimed in claim 1, wherein the at least one positioning post extends from the rear end toward the direction away from the rear end and gradually decreases in outer diameter to form a cone shape, and has a guide ramp disposed at the front end, spatially opposite the at least one positioning hole, for guiding the at least one positioning post into the at least one positioning hole when the battery compartment is assembled close to the shelf.

7. The drainage mechanism as claimed in claim 1, wherein the at least one positioning post includes two positioning posts, the at least one positioning hole includes two positioning holes, the two positioning holes are respectively located on two opposite sides of the mounting hole, and the drainage hole is located between the two positioning posts.

8. The drainage mechanism as claimed in claim 1, wherein the drainage adapter includes a mounting portion and a channel, wherein the mounting portion is located between the receiving portion and the pipe connection portion, and the channel passes through the receiving portion, the mounting portion and the pipe connection portion, wherein the mounting portion is fixed to the rear side plate by welding, gluing or threading, and the pipe connection portion passes through the rear side plate through the mounting hole.

9. The drainage mechanism as claimed in claim 8, wherein the shelf further includes an opening disposed on the bottom plate and connected to the rear side plate, the opening being spatially relative to the mounting portion, allowing the mounting portion to be secured to the rear side plate through the opening.

10. The drainage mechanism as claimed in claim 8, wherein the receiving portion extends from the mounting portion in a direction away from the mounting portion and gradually decreases in outer diameter to form a cone shape.

11. The drainage mechanism as claimed in claim 1, wherein the bottom plate of the shelf has an inclination angle relative to the horizontal surface of the cabinet frame, the inclination angle being between 10 degrees and 20 degrees.

12. The drainage mechanism as claimed in claim 1 or 11, wherein a bottom side plate of the battery compartment is assembled and attached to the bottom plate of the layer, and the drainage hole is disposed between the bottom side plate and the rear end of the battery compartment.

13. The drainage mechanism as claimed in claim 12, wherein the bottom side plate connects to the drainage hole to form a stepped structure.

14. The drainage mechanism as claimed in claim 1, wherein the battery compartment further includes a receiving space configured to receive a battery, the receiving space communicating with the drainage adapter through the drainage hole, the drainage hole being located at the bottom end of the receiving space.

15. The drainage mechanism as claimed in claim 1, wherein the pipe connection is a pagoda connector.
