Description

Technical Field

[0001] The present invention relates to the technical field of battery packs, and in particular to a high-precision alignment and installation battery pack and an installation trolley thereof. Background Art

[0002] With the development of the transportation industry, electric aircraft, as a new type of transportation, has attracted widespread attention due to its advantages of energy saving, environmental protection, high efficiency, low energy consumption, near zero emissions, and low noise and vibration levels. The core components of electric aircraft include motors, battery packs, and electronic control components.

[0003] At present, in order to improve the operating efficiency of aircraft, battery packs are produced in a detachable type. The existing detachable type is screwed to the mounting frame of the battery compartment of the electric aircraft through multiple sets of bolts. The bolts and the battery pack are independent entities. When disassembling, the battery pack is first supported by a jacking device, and the bolts are manually unscrewed. When assembling, the battery pack is first supported by a jacking device, and the bolts are manually tightened.

[0004] However, the bolts are easy to fall off the battery pack during the disassembly and assembly process. If the bolts are not discovered in time after falling, the spirals will cause damage to the aircraft tires, which may easily cause safety accidents. At the same time, disassembly requires manual operation, and the overall disassembly efficiency is low.

[0005] Based on this, the present invention designs a high-precision alignment and installation battery pack and its installation cart to solve the above problems. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides a high-precision alignment and installation battery pack and an installation trolley thereof.

The bottom of the battery panel 21 is fixedly connected to the protective plate 24, and the four corners of the protective plate 24 are provided with first straight holes 25, and the first straight hole 25 is located directly below the screw-on quick-install assembly.

[0043] During installation, the battery panel 21 is driven to move to the bottom of the mounting frame 1, and then the battery panel 21 is pushed to move toward the mounting frame 1. The positioning and alignment assembly aligns and positions the screw-type quick-install assembly thread, and then the guide assembly guides the battery panel 21, and the screw-type quick-install assembly is docked, and then the screw-type quick-install assembly is driven to be assembled. After the screw-type quick-install assembly is assembled, the battery pack can be aligned and installed with high precision.

[0044] During disassembly, the screw-on quick-install assembly is driven to separate and open, and the positioning and alignment assembly positions the screw-on quick-install assembly when the screw-on quick-install assembly is separated and opened.

The second annular connecting plate 28 is fixedly connected to the portion of the first threaded rod 22 where no thread is provided. The second annular connecting plate 28 is provided with a plug hole 29 plugged with the plug rod 213. When the first threaded rod 22 is completely separated from the threaded sleeve 212, the bottom of the second annular connecting plate 28 is flush with the top of the plug rod 213, and the plug hole 29 is located directly above the plug rod 213. The first threaded rod 22 and the hexagon socket nut 23 drive the plug hole 29 of the second annular connecting plate 28 to be inserted outside the plug rod 213 due to the gravity of the first threaded rod 22 and the hexagon socket nut 23.

[0049] The second annular connecting plate 28 and the fixing ring 210 are made of magnetic materials, and the magnetic properties of the second annular connecting plate 28 and the fixing ring 210 are opposite;

After the first threaded rod 22 of the screw-on quick-install assembly is in place, the first threaded rod 22 is pushed upward to be connected with the threaded sleeve 212. At the same time, the plug-in rod 213 and the insertion hole 29 are completely separated, driving the hexagon socket nut 23 of the screw-on quick-install assembly to rotate, and the hexagon socket nut 23 drives the first threaded rod 22 to rotate, and the first threaded rod 22 rotates toward the threaded sleeve 212. The threaded sleeve 212 and the first threaded rod 22 are threadedly connected for assembly processing.

[0051] When disassembling, the hexagonal nut 23 of the screw-on quick-install assembly is driven to rotate, and the hexagonal nut 23 drives the first threaded rod 22 to rotate, and the first threaded rod 22 is separated and opened from the threaded sleeve 212. When the first threaded rod 22 and the threaded sleeve 212 of the screw-on quick-install assembly are separated and opened, the insertion hole 29 of the second annular connecting plate 28 of the positioning alignment assembly is directly above the plug-in rod 213. Through magnetic attraction and gravity, the second annular connecting plate 28 drives the insertion hole 29 to be inserted into the outside of the plug-in rod 213. The plug-in rod 213 and the insertion hole 29 cooperate to thread-position the first threaded rod 22 of the screw-on quick-install assembly. When the battery panel 21 moves, the thread of the first threaded rod 22 of the screw-on quick-install assembly is always in the state when the first threaded rod 22 of the screw-on quick-install assembly is separated and opened from the threaded sleeve 212.

At the same time, the screw-on quick-release assembly is integrated with the battery panel 21, and there is no need to consider the problem of the screw-on quick-release assembly and the battery panel 21 falling off, thus avoiding safety hazards caused by the falling off of the screw-on quick-release assembly. The device is particularly suitable for the harsh use environment of electric aircraft.
