Description

Technical Field

[0001] The utility model relates to the technical field of lifting platforms, in particular to a movable lifting platform for battery pack installation. Background Technique

[0002] With the development of aviation technology and the improvement of human living needs, electric vertical takeoff and landing (eVTOL) aircraft have emerged as the times require. It combines the performance of helicopters and fixed-wing aircraft. It can take off and land vertically, reducing the requirements for takeoff and landing sites. It can also provide a longer range and a faster flight speed. It is safe and reliable, has a simple structure, clean energy, and low noise.

[0003] Power provided by batteries is the core difference between eVTOL aircraft and traditional aircraft. During the test flight stage, the battery pack needs to be disassembled many times for inspection tests or maintenance. Since the current battery charging efficiency is low, in order to reduce the flight interval time and improve the operation efficiency, replacing the battery pack has become a more primary choice. Devices that can quickly and accurately install the battery pack have become an urgent need at present. The shelf products on the market are all lifting platforms suitable for the installation of new energy vehicle battery packs and cannot be fully applicable to the installation of aircraft battery packs.

[0004] Moreover, the development process of eVTOL aircraft is short, there is a lack of experience in battery pack installation, and the relevant supporting facilities are not perfect. The existing battery pack installation platforms are designed for new energy vehicles, and their maximum lifting height is 1.9 meters. The battery packs of eVTOL aircraft are mostly arranged on the wings. Considering the safety of passengers, most of them are upper single wings, and the distance from the wing battery pack to the ground is far. The lifting distance of 1.9 meters cannot meet the installation requirements; the bottom plate of the wing battery pack conforms to the lower surface skin of the wing. For wings with anhedral angles, there is an angle between the bottom plate of the battery pack and the ground. The installation plane of the existing lifting platform is parallel to the ground and cannot adjust the installation angle; most of the installation planes of the existing battery pack installation platforms are rubber pads with a large friction coefficient. The battery pack is heavy and cannot be adjusted in position on the platform. Fine-tuning the battery pack depends on moving the installation platform, and it is very difficult to achieve fine control. Summary of the Utility Model

By driving the two first double-headed lead screws 347 to rotate synchronously through the first driving mechanism, when the first double-headed lead screw 347 rotates, it drives the lower auxiliary frame 32 to rotate downward or upward along the first rotating shaft 333. At the same time, the first rotating roller 342 rotates, causing the first double-headed lead screw 347 to tilt and avoid jamming, thereby adjusting the rotation angle of the battery pack installation platform 3 around the Y-axis, and further facilitating the installation of the battery pack.

[0043] Among them, the first driving mechanism includes a first attitude angle adjustment handwheel 348 fixedly sleeved on the side wall of the first double-headed lead screw 347.

The second rotating roller 362 is threadedly connected to the threaded portion of the second double-headed lead screw 367, and the rotation of the second double-headed lead screw 367 is driven by a second driving mechanism. When the second double-headed lead screw 367 rotates, it drives the upper mounting platform 31 to rotate downward or upward along the second rotating shaft 353. At the same time, the second rotating roller 362 rotates, causing the second double-headed lead screw 367 to tilt to avoid jamming, thereby adjusting the rotation angle of the battery pack mounting platform 3 around the X-axis, and further facilitating the installation of the battery pack.

[0047] Among them, the second driving mechanism includes a second attitude angle adjusting handwheel 368 fixedly sleeved on the side wall of the second double-headed lead screw 367. A second transmission mechanism is arranged between the two second double-headed lead screws 367.

[0048] Specifically, the second transmission mechanism includes two symmetrically arranged second track wheels 3691 fixedly sleeved on the side wall of the second double-headed lead screw 367. A second track 3692 is sleeved on the side wall of the second track wheel 3691. Rotate the second attitude angle adjusting handwheel 368. The rotation of the second attitude angle adjusting handwheel 368 drives the rotation of the second track wheel 3691, and drives another second track wheel 3691 and the second double-headed lead screw 367 to rotate synchronously through the second track 3692.

[0049] A plurality of arrayed mounting seats 311 are fixedly connected to the top of the battery pack mounting platform 3. A ball 312 is arranged in the mounting seat 311. The battery pack moves back and forth along the X-axis and Y-axis and rotates around the Z-axis on the balls 312 of the battery pack mounting platform 3, continuously adjusting the position of the battery pack so that the positioning pin passes through the positioning holes of the battery pack and the machine body, thereby facilitating the adjustment of the position of the battery pack and further facilitating the installation of the battery pack. When the balls 312 roll, a certain thrust is required.

[0050] Working principle: When installing the battery pack, lock the brake of the locking wheel 11, place the battery pack on the battery pack installation platform 3. After placing it stably, release the brake of the locking wheel 11, move the whole device to the lower side of the wing or strut battery compartment, adjust the position of the battery pack installation platform 3, and lock the brake of the locking wheel 11;

[0051] During adjustment, control the rise of the battery pack installation platform 3 evenly and regularly. When approaching the installation position, slow down the rising speed. During the rising process, it can pause to finely adjust the position and angle of the battery pack so as to push the battery pack more precisely and align with the positioning holes.

[0052] The specific adjustment process is as follows. When the battery pack is pushed in part, adjust the angle of the battery pack installation platform 3. During adjustment, rotate the first attitude angle adjustment handwheel 348. The rotation of the first attitude angle adjustment handwheel 348 drives the rotation of the first track wheel 3491, and drives the rotation of another first track wheel 3491 and the first double-headed screw rod 347 through the first track 3492. When the first double-headed screw rod 347 rotates, it drives the lower auxiliary frame 32 to rotate downward or upward along the first rotating shaft 333. At the same time, the first rotating roller 342 rotates, making the first double-headed screw rod 347 tilt to avoid jamming, thereby adjusting the rotation angle of the battery pack installation platform 3 around the Y axis, and the angle range is -3° to +4°.

[0053] At the same time, rotate the second attitude angle adjustment handwheel 368. The rotation of the second attitude angle adjustment handwheel 368 drives the rotation of the second track wheel 3691, and drives the rotation of another second track wheel 3691 and the second double-headed screw rod 367 through the second track 3692. When the second double-headed screw rod 367 rotates, it drives the upper installation platform 31 to rotate downward or upward along the second rotating shaft 353. At the same time, the second rotating roller 362 rotates, making the second double-headed screw rod 367 tilt to avoid jamming, thereby adjusting the rotation angle of the battery pack installation platform 3 around the X axis, and the angle range is -2° to +4°.

[0054] Moreover, the battery pack translates back and forth along the X axis and Y axis and rotates around the Z axis on the balls 312 of the battery pack installation platform 3, continuously adjusting the position of the battery pack so that the positioning pin passes through the positioning holes of the battery pack and the airframe, thus facilitating the adjustment of the position of the battery pack. Slowly push the battery pack to the installation position, tighten the connecting bolts, lower the battery pack installation platform 3 to a safe distance, and move the whole device away.

[0055] When disassembling the battery pack, push the entire device under the battery pack to be disassembled, lock the brake of the locking wheel 11, control the battery pack installation platform 3 to rise. When approaching the bottom plate of the battery pack, slow down the rising speed, adjust the angle of the battery pack installation platform 3 in the same way as in the process of installing the battery pack, so that the angle of the battery pack installation platform 3 can fit the angle of the bottom plate of the battery pack, slowly rise until the battery pack installation platform 3 touches the bottom plate of the battery pack, remove the fastening bolts, and let the battery pack installation platform 3 loaded with the battery pack descend uniformly to a safe height, then move the battery pack to the specified position.
