Description

Technical Field

[0001] This utility model relates to the field of eVTOL, and more specifically, to a packaging device for an eVTOL propeller. Background Technology

[0002] In recent years, with the rapid development of the eVTOL industry, more and more eVTOL companies have launched their products. However, due to the large size of eVTOLs, transportation costs can be very high when companies participate in product exhibitions or conduct test flights at dedicated sites.

[0003] The eVTOL structure mainly consists of a rotor assembly and a fuselage. The rotor assembly includes an oversized propeller. Since eVTOL propellers are mostly made of high-strength, low-density composite materials such as carbon fiber, conventional transportation methods, where the propeller is transported as part of the entire aircraft, can easily damage it. Furthermore, if the propeller blades are removed, they and other components such as the hub must be packaged and transported separately, requiring on-site assembly, which hinders rapid disassembly and assembly and results in excessive time costs. Utility Model Content

[0004] The purpose of this invention is to provide a packaging device for eVTOL propellers to solve the problem of easy damage to eVTOL propellers during transportation, while improving the efficiency of propeller assembly and disassembly.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A packaging device for an eVTOL propeller, the device comprising:

[0007] Box;

[0008] The propeller mounting base is fixedly connected to the bottom of the housing. The top of the propeller mounting base is provided with a first mounting groove and a second mounting groove. The first mounting groove is arranged radially along the propeller mounting base, and the second mounting groove is arranged circumferentially along the propeller mounting base. When the eVTOL propeller is installed on the propeller mounting base, the first mounting groove corresponds to the mounting hole on the propeller hub.

[0009] The device includes a limiting cover with a slot and a connecting post. When the eVTOL propeller is installed on the propeller mounting base, the slot of the limiting cover is used to engage and fix the root of the propeller blade, and the connecting post is used to fix it in the second mounting slot.

[0010] In the above structure, the first mounting slot can accommodate propellers of different sizes and specifications; the locking of the limiting cover can prevent the propeller from rotating relative to the housing and damaging the blades, thus protecting the propeller's safety during transportation.

[0011] In this device, to improve connection stability and prevent detachment, the first mounting groove is a dovetail groove;

[0012] To facilitate the installation and fixing of the connecting column, the second mounting groove is an arc-shaped through groove.

[0013] Preferably, there are multiple first mounting slots and multiple second mounting slots arranged in a crisscross pattern, which will provide stable vertical support.

[0014] To ensure that the supporting force is evenly distributed between the eVTOL propeller and the propeller mounting base, preferably, the propeller mounting base is disc-shaped, and the first mounting grooves are evenly distributed around the center of the disc.

[0015] In the limiting cover, to facilitate the locking of the propeller blade root and for easy inspection, the locking groove is preferably a U-shaped groove.

[0016] Preferably, a rubber damping layer is fixedly connected to the wall of the U-shaped groove.

[0017] To clarify the specific structure of the housing, preferably, the housing includes a top plate, a bottom plate, and side plates arranged around the perimeter, wherein the top plate, bottom plate, and side plates together form a propeller mounting cavity, and the bottom of the propeller mounting base is fixedly connected to the bottom plate.

[0018] In this device, handles are provided on the outside of the top plate and side plates to facilitate the transportation of the box.

[0019] Preferably, the box is made of wood, which facilitates the fixing and connection of the top plate, bottom plate and four side plates by screws, steel strips or the like.

[0020] The beneficial effects of this utility model are:

[0021] Current common methods for transporting eVTOL propellers typically involve shipping the entire unit together, which makes the blades susceptible to damage during transport and results in a large overall size and higher transportation costs. This packaging device introduces a propeller holder and a retaining cover. The propeller holder has a first mounting slot and a second mounting slot on its top. The first mounting slot is radially positioned along the propeller holder, while the second mounting slot is circumferentially positioned. Because the first mounting slot is radially positioned, it can accommodate propellers of different sizes, offering strong adaptability. Furthermore, the retaining cover prevents the propeller from rotating relative to the housing, thus protecting the blades and ensuring the propeller's safety during transport. This device solves the problem of easy damage to eVTOL propellers during transport, while also improving propeller assembly and disassembly efficiency, avoiding excessive disassembly of the propeller during transit, and reducing transportation costs.

[0033] Example 1:

[0034] like Figures 1 to 5 As shown, a packaging device for an eVTOL propeller includes:

[0035] Box 1;

[0036] The propeller mounting base 2 is fixedly connected to the bottom of the housing 1. The top of the propeller mounting base 2 is provided with a first mounting groove 21 and a second mounting groove 22. The first mounting groove 21 is arranged radially along the propeller mounting base 2, and the second mounting groove 22 is arranged circumferentially along the propeller mounting base 2. When the eVTOL propeller 4 is installed on the propeller mounting base 2, the first mounting groove 21 corresponds to the mounting hole 41 on the propeller hub.

[0037] And a limiting cover 3, which is provided with a slot 31 and a connecting post 32. When the eVTOL propeller 4 is installed on the propeller mounting base 2, the slot 31 of the limiting cover 3 is used to engage and fix the root of the propeller blade, and the connecting post 32 is used to fix it in the second mounting groove 22.

[0038] When using this packaging device, first determine the dimensions of the housing 1 based on the maximum shape of the eVTOL propeller to be packaged, and then determine the center point for fixing the propeller. Next, fix the propeller mounting bracket 2 to the center point of the housing 1. Then, install the eVTOL propeller 4 onto the propeller mounting bracket 2, as follows: Figure 3 and Figure 4 As shown, the first mounting groove 21 corresponds to the mounting hole 41 on the propeller hub. Since the first mounting groove 21 is arranged radially along the propeller mounting base 2, it can accommodate propellers of different sizes. The propeller mounting base 2 and the propeller can then be fixed together with bolts and nuts, where the bolts pass through the mounting hole 41 on the hub, and the nuts are connected to the bolts. Furthermore, when the eVTOL propeller 4 is mounted on the propeller mounting base 2, as... Figure 5 As shown, the retaining cover 3's slot 31 engages and is fixed to the root of the propeller blade, and the connecting column 32 is fixedly connected to the second mounting slot 22. The engagement of the retaining cover 3 can prevent the propeller from rotating relative to the housing 1 and damaging the blade, thus protecting the propeller's safety during transportation.

[0039] In the above structure, the nut can slide to a specific installation position within the first mounting groove 21, corresponding to propellers of different sizes and specifications.

[0040] like Figure 2 As shown, the first mounting groove 21 is a dovetail groove, and the second mounting groove 22 is an arc-shaped through groove. The dovetail groove of the first mounting groove 21 can improve the connection stability and prevent detachment; the arc-shaped through groove of the second mounting groove 22 can facilitate the installation and fixation of the connecting post 32.

[0041] Preferably, there are multiple first mounting slots 21 and second mounting slots 22, which are arranged in a crisscross pattern to provide stable vertical support.

[0042] To ensure that the supporting force is evenly distributed between the eVTOL propeller 4 and the propeller mounting base 2, the propeller mounting base 2 is disc-shaped, and the first mounting grooves 21 are evenly distributed around the center of the disc. For example... Figure 2 As shown, there are five first mounting slots 21, which are evenly distributed around the center of the disc.

[0043] To facilitate the clamping of the propeller blade root and for easy inspection, the clamping groove 31 is a U-shaped groove.

[0044] Preferably, a rubber damping layer is fixedly connected to the wall of the U-shaped groove to avoid rigid contact between the limiting cover 3 and the root of the propeller blade, and also to ensure the damping of the limiting cover 3 during transportation.

[0045] To clarify the specific structure of the housing 1, the housing 1 includes a top plate, a bottom plate, and side plates arranged around the perimeter. The top plate, bottom plate, and side plates together form a propeller mounting cavity, and the bottom of the propeller mounting base 2 is fixedly connected to the bottom plate.

[0046] To facilitate the transfer of the box 1, handles are provided on the outside of the top plate and side plates; a handle structure can also be provided on the top plate.

[0047] In this device, the box 1 is preferably a wooden box, which facilitates the fixing and connection of the top plate, bottom plate and four side plates by screws, steel strips, etc.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0049] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
