Description

Technical Field

[0001] This invention relates to the field of battery pack support technology, specifically to an electric boat battery pack support base and a battery replacement method based on the support base. Background Technology

[0002] As the power source of electric boats, the battery packs of electric boats require frequent maintenance and replacement. They usually need to be lifted and replaced using a gantry crane system installed in the cabin. The existing battery pack support structure is the same as that of conventional shelving. When using the gantry crane system for lifting operations, manual assistance is required to pull the battery pack out or push it into the support. Due to the large weight of the battery pack, the pushing and pulling process is laborious, and the accuracy of manual pushing and pulling is poor. There may be impacts between the battery pack and the support, which may affect the battery pack's lifespan. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a battery pack support for an electric boat and a battery replacement method based on the support, which can connect the battery pack when the flip plate is unfolded, and facilitate the pushing in and pulling out of the battery pack. At the same time, the flip plate can be retracted after the upper battery pack replacement operation is completed to avoid obstructing the battery pack.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an electric boat battery pack support base, including a cabinet, a support leg at the bottom of the cabinet, multiple support partitions in the cabinet, a back baffle on the cabinet behind the compartment formed by the support partitions, and a flip-up plate on the support partition on the front of the compartment.

[0005] The cabinet below the flip panel is equipped with lifting rods, which extend to both sides of the cabinet. One end of each lifting rod is threaded and the other end is smooth. The lower end of the threaded rod is connected to the drive motor via a transmission belt.

[0006] The threaded rod comprises multiple rod sections. The bottom end of the threaded rod is provided with a T-shaped connecting hole. The upper half of the T-shaped connecting hole is provided with a fixed upright plate. The top end of the threaded rod is provided with a lever plate, which is located in the upper half of the T-shaped connecting hole.

[0007] In a preferred embodiment, the flip plate is provided with an ear plate on one side, and the flip plate is hinged to the support partition through the ear plate and connecting pin.

[0008] In a preferred embodiment, the flip plate has an opening, and a rotating cylinder is installed in the opening.

[0009] In a preferred embodiment, vertical grooves are provided on the inner walls of both sides of the opening on the flip plate, and sliders are provided in the vertical grooves. The rotating cylinder is fixed between the two sliders by a rotating cylinder shaft passing through itself. A vertical guide rod is provided in the vertical groove and passes through the slider, and a spring is sleeved on the guide rod below the slider.

[0010] In a preferred embodiment, the cabinet has T-shaped guide grooves on both sides of the front, and T-shaped blocks that cooperate with the T-shaped guide grooves are provided on the same side of both ends of the lifting rod. An end extension plate is also provided on the same side of both ends of the lifting rod, and a threaded hole is provided on the end extension plate. The part of the threaded rod with external threads passes through the threaded hole.

[0011] The battery replacement method based on the above-mentioned electric boat battery pack support includes the following steps:

[0012] 1) Control the start of the drive motor and, in conjunction with the transmission belt, drive the bottom section of the threaded rod to rotate;

[0013] 2) The bottom segment of the threaded rod rotates, causing the bottom lifting rod to descend and the flipping plate to flip around the connecting pin to a horizontal state;

[0014] 3) After the bottom flip plate flips to a horizontal position, the external thread on the threaded rod disengages from the threaded hole, and the lever at the upper end of the lower threaded rod rotates 360° in the T-shaped connecting hole of the upper threaded rod and contacts the fixed upright plate.

[0015] 4) The drive motor continues to run, causing the upper threaded rod to rotate under the action of the lower threaded rod's lever, thus raising the upper lifting rod and repeating steps 2)-4).

[0016] 5) During the repeated operation of step 4), the multiple flip-up panels are unfolded;

[0017] 6) Use the gantry crane system to replace the battery pack in the cabinet.

[0018] In the preferred embodiment, in step 6), the battery replacement is carried out from top to bottom. After the battery pack in one compartment is replaced, the lifting rod is raised and the flipping plate is flipped towards the inside of the cabinet by controlling the drive motor to reverse.

[0019] In a preferred embodiment, the flipping plate has a flipping angle of less than 90°, and after the flipping plate completes the upward flipping action, the flipping plate is in an inclined state.

[0020] In a preferred embodiment, the drive motor is a geared motor.

[0021] In a preferred embodiment, the lifting height of the lifting rod is the same as the height of the external thread for each revolution of the threaded rod.

[0022] The electric boat battery pack support base and battery replacement method based on the support base provided by the present invention have the following beneficial effects by adopting the above structure and method:

[0023] (1) During the battery replacement process, the flip panel can be retracted from top to bottom or unfolded from bottom to top. While achieving the purpose of connecting the hoisted battery, it can avoid obstructing the installation or removal of the lower battery and reduce the risk of battery collision.

[0024] (2) The rotating drum can reduce the labor intensity when the battery pack is pulled out or pushed in, and after the flip plate is flipped, the rotating drum can be used to press the battery pack tightly to avoid the risk of collision of the battery pack in the compartment caused by the swaying of the ship.

[0040] Example 2:

[0041] The battery replacement method based on the electric boat battery pack support base described in Example 1 includes the following steps:

[0042] 1) Control the start of the drive motor 9 and, in conjunction with the transmission belt 10, drive the bottom section of the threaded rod 7 to rotate;

[0043] 2) The bottom segment of the threaded rod 7 rotates and drives the bottom lifting rod 5 to descend, causing the flipping plate 3 to flip around the connecting pin 301 to a horizontal state;

[0044] 3) After the bottom flip plate 3 flips to the horizontal state, the external thread 701 on the threaded rod 7 disengages from the threaded hole 503, and the lever plate 18 at the upper end of the lower threaded rod 7 rotates 360° in the T-shaped connecting hole 16 of the upper threaded rod 7 and contacts the fixed upright plate 17.
