Description

Technical Field

[0001] This utility model relates to the field of aircraft technology, and in particular to a wing structure and an electric vertical take-off and landing aircraft. Background Technology

[0002] With the gradual development of the low-altitude economy, various types of electric vertical takeoff and landing (eVTOL) aircraft are being rapidly developed. Batteries, as the power source for eVTOLs, play a crucial role in their development. Installing the battery pack inside the wing not only allows for efficient use of the wing's internal space but also utilizes the weight of the battery pack to offset some of the lift generated by the wing during flight, thus partially unloading the wing. In related technologies, the battery pack is detachably connected to the wing, allowing for power replenishment by replacing the battery pack. Compared to traditional charging methods, this significantly saves time and improves the operational efficiency of eVTOLs. However, the installation and removal of the battery pack in these technologies remains somewhat inconvenient. Utility Model Content

The second mounting portion and the second limiting portion are arranged at an angle. The mounting joint further includes a second reinforcing portion connecting the second mounting portion and the second limiting portion. There are two second reinforcing portions, which are located at both ends of the boundary line between the second mounting portion and the second limiting portion. The two first reinforcing portions are located between the two second reinforcing portions.

[0018] In one embodiment, the wing body includes an upper skin, a lower skin, a front spar, a rear spar, and a rib structure. The upper skin and the lower skin are connected and define a cavity. The front spar, the rear spar, and the rib structure are all disposed within the cavity to maintain its stability. The front spar and the rear spar are respectively disposed at the front end and the rear end of the cavity. The rib structure includes multiple ribs spaced apart in the left-right direction.

[0027] In the aforementioned wing structure, when a battery pack needs to be installed on the wing body, the inlet and outlet can be opened first through the pack opening cover, and then the battery pack can be pushed into the mounting cavity through the inlet and outlet, causing the first and second limiting parts to abut against each other, thereby completing the positioning of the battery pack within the mounting cavity. Simultaneously with or after the abutment of the first and second limiting parts, the first and second limiting parts can be detachably connected, ensuring the battery pack is securely installed within the mounting cavity. Finally, the inlet and outlet are closed through the pack opening cover, completing the assembly of the battery pack onto the wing body. When the battery pack's charge is insufficient and needs replacement, the inlet and outlet can be opened first through the pack opening cover, then the connection between the first and second limiting parts can be released, and then the battery pack can be removed from the mounting cavity through the inlet and outlet, completing the removal of the battery pack from the wing body. This allows a fully charged battery pack to be installed within the mounting cavity. In the aforementioned wing structure, the first limiting part and the second limiting part serve as both mounting elements and positioning elements for the battery pack. Therefore, the battery pack of the aforementioned wing structure is very easy to install and remove, which can greatly save the time of installing and removing the battery pack and improve the operating efficiency of eVTOL.

[0041] like Figures 1-5 As shown, an embodiment of the present invention, an airfoil structure 10, is presented. The airfoil structure 10 includes an airfoil body 200, a battery pack 300, and a mounting assembly 400. The airfoil body 200 has a mounting cavity 202a. The airfoil body 200 has an inlet / outlet 202b communicating with the mounting cavity 202a. The airfoil body 200 includes a cover 222 capable of opening and closing the inlet / outlet 202b. The battery pack 300 is located within the mounting cavity 202a. The battery pack 300 can enter and exit the mounting cavity 202a through the inlet / outlet 202b. The mounting assembly 400 has a first limiting portion 412 and a second limiting portion 422. The first limiting portion 412 is disposed on the cavity wall of the mounting cavity 202a. The second limiting portion 422 is disposed on the outer wall of the battery pack 300. In the direction in which the battery pack 300 enters and exits the mounting cavity 202a, the first limiting portion 412 and the second limiting portion 422 are stacked and detachably connected. The second limiting part 422 is closer to the inlet / outlet 202b than the first limiting part 412.

[0042] In the aforementioned wing structure 10, when it is necessary to assemble the battery pack 300 on the wing body 200, the inlet and outlet 202b can be opened first through the pack opening cover 222, and then the battery pack 300 can be pushed into the mounting cavity 202a through the inlet and outlet 202b, so that the first limiting part 412 and the second limiting part 422 abut against each other, thereby completing the positioning of the battery pack 300 in the mounting cavity 202a. At the same time as the first limiting part 412 and the second limiting part 422 abut against each other, or after the first limiting part 412 and the second limiting part 422 abut against each other, the first limiting part 412 and the second limiting part 422 can be detachably connected, thereby making the battery pack 300 firmly installed in the mounting cavity 202a. Finally, the inlet and outlet 202b is closed through the pack opening cover 222 to complete the assembly of the battery pack 300 on the wing body 200. When the battery pack 300 needs to be replaced due to insufficient power, the inlet / outlet 202b can be opened through the pack cover 222, the connection between the first limiting part 412 and the second limiting part 422 can be released, and then the battery pack 300 can be taken out from the mounting cavity 202a through the inlet / outlet 202b, thus completing the removal of the battery pack 300 from the wing body 200. A fully charged battery pack 300 can then be installed in the mounting cavity 202a. In the aforementioned wing structure 10, the first limiting part 412 and the second limiting part 422 serve as both mounting elements and positioning elements for the battery pack 300. Therefore, the battery pack 300 of the aforementioned wing structure 10 is very easy to install and remove, greatly saving time and improving the operating efficiency of eVTOL.

[0043] In this embodiment, the battery pack 300 includes a housing and components such as a battery module, an electronic control unit, and a cooling device arranged inside the housing.

[0044] In this embodiment, the mounting assembly 400 further includes a self-locking sleeve 430 and a mounting bolt 440. The first limiting portion 412 has a first mounting hole. The second limiting portion 422 has a second mounting hole. The self-locking sleeve 430 is disposed within the first mounting hole. The mounting bolt 440 passes through the second mounting hole and is screwed onto the self-locking sleeve 430. Thus, after the first limiting portion 412 and the second limiting portion 422 abut against each other, the first limiting portion 412 and the second limiting portion 422 can be easily detachably connected, and installation and disassembly can be completed simply by tightening the bolt. This design is simple to operate, requires no special tools, and is safe and convenient. It is understood that in other embodiments, the first limiting part 412 and the second limiting part 422 can also be detachably connected while the first limiting part 412 and the second limiting part 422 are abutting. For example, when the first limiting part 412 has a bayonet and the second limiting part 422 has a buckle, the buckle is engaged with the bayonet while the first limiting part 412 and the second limiting part 422 are abutting, thus realizing the detachable connection of the first limiting part 412 and the second limiting part 422.

[0045] In this embodiment, both the first limiting part 412 and the second limiting part 422 are aluminum alloy limiting parts, meaning that both the first limiting part 412 and the second limiting part 422 are made of aluminum alloy. The self-locking threaded sleeve 430 is a self-locking wire threaded sleeve, meaning that the self-locking threaded sleeve 430 is made of steel. This not only facilitates a secure connection between the battery pack 300 and the wing body 200, but also helps reduce the weight of the wing structure 10. It is understood that in other embodiments, the first limiting part 412 and the second limiting part 422 may also be made of steel.

[0046] In this embodiment, multiple second limiting portions 422 are arranged circumferentially around the battery pack 300, and multiple first limiting portions 412 are also present. In the direction in which the battery pack 300 enters and exits the mounting cavity 202a, each first limiting portion 412 and a second limiting portion 422 are stacked and detachably connected. This not only facilitates a secure connection between the battery pack 300 and the wing body 200 but also helps reduce the weight of the wing structure 10. It is understood that in other embodiments, at least one of the first limiting part 412 and the second limiting part 422 can be an annular part (when the second limiting part 422 is an annular part, the second limiting part 422 is sleeved on the outer peripheral wall of the battery pack 300, and when the first limiting part 412 is an annular part, the outer peripheral wall of the first limiting part 412 is provided on the cavity wall of the mounting cavity 202a, and the central through hole of the first limiting part 412 can allow the battery pack 300 to pass through), and there can be multiple detachable connection points between the first limiting part 412 and the second limiting part 422.

[0047] In this embodiment, in the direction of the battery pack 300 entering and exiting the mounting cavity 202a, the surface of the first limiting part 412 near the second limiting part 422 is the first mounting surface, and the surface of the second limiting part 422 near the first limiting part 412 is the second mounting surface. The first mounting surfaces of the multiple first limiting parts 412 are coplanar, and the second mounting surfaces of the multiple second limiting parts 422 are coplanar. This greatly facilitates the assembly and disassembly of the battery pack 300. It is understood that in other embodiments, the first mounting surfaces of the multiple first limiting parts 412 may not be coplanar, and there may be a height difference; correspondingly, the second mounting surfaces of the multiple second limiting parts 422 may have a corresponding height difference.

[0048] In this embodiment, the mounting assembly 400 includes a mounting connector 410 and a mounting joint 420. The mounting connector 410 includes a first mounting portion 414 and a first limiting portion 412 connected together. The first mounting portion 414 is disposed on the cavity wall of the mounting cavity 202a. The mounting joint 420 includes a second mounting portion 424 and a second limiting portion 422 connected together, with the second mounting portion 424 disposed on the outer wall of the battery pack 300. This facilitates the placement of the first limiting portion 412 on the cavity wall of the mounting cavity 202a and the second limiting portion 422 on the outer wall of the battery pack 300.

[0049] In this embodiment, the first mounting portion 414 and the first limiting portion 412 are orthogonal (perpendicular). This makes it easier for the first limiting portion 412 to be disposed on the cavity wall of the mounting cavity 202a.

[0050] In this embodiment, the second mounting portion 424 and the second limiting portion 422 are orthogonal (perpendicular). This makes it easier for the second limiting portion 422 to be disposed on the outer wall of the battery pack 300.

[0051] In this embodiment, as Figure 6 As shown, the first mounting part 414 is detachably connected to the cavity wall of the mounting cavity 202a by bolts 450. This makes it very convenient for the first limiting part 412 to be provided on the cavity wall of the mounting cavity 202a.

[0052] In this embodiment, the second mounting part 424 is detachably connected to the battery pack 300 by bolts. This makes it very convenient for the second limiting part 422 to be provided on the outer wall of the battery pack 300.

[0053] In this embodiment, as Figure 5 As shown, in the direction from the outer wall of the battery pack 300 to the cavity wall of the mounting cavity 202a, the first limiting part 412 sequentially has a first plate segment 412a and a second plate segment 412b. The thickness of the first plate segment 412a is greater than the thickness of the second plate segment 412b, and the thickness of the second plate segment 412b is the same as the thickness of the first mounting part 414. In this way, not only is it beneficial to firmly fix the battery pack 300 to the cavity wall of the mounting cavity 202a, but it is also beneficial to reduce the weight of the wing structure 10.

[0054] In this embodiment, as Figure 5 and Figure 6 As shown, the first mounting portion 414 and the first limiting portion 412 are arranged at an angle. The mounting connector 410 also includes a first reinforcing portion 416 connecting the first mounting portion 414 and the first limiting portion 412. There are two first reinforcing portions 416, which are located at both ends of the boundary line between the first mounting portion 414 and the first limiting portion 412. The second mounting portion 424 and the second limiting portion 422 are arranged at an angle. The mounting section 420 also includes a second reinforcing portion 426 connecting the second mounting portion 424 and the second limiting portion 422. There are two second reinforcing portions 426, which are located at both ends of the boundary line between the second mounting portion 424 and the second limiting portion 422. The two first reinforcing portions 416 are located between the two second reinforcing portions 426. In this way, it is not only beneficial for the battery pack 300 to be firmly fixed to the cavity wall of the mounting cavity 202a, but also for the positioning and installation of the battery pack 300.

[0055] In this embodiment, as Figure 3 and Figure 4As shown, the wing body 200 includes an upper skin 210, a lower skin 220, a front sparsity 230, a rear sparsity 240, and a rib structure 250. The upper skin 210 and the lower skin 220 are connected and define a cavity 202. The front sparsity 230, the rear sparsity 240, and the rib structure 250 are all located within the cavity 202 to maintain the stability of the cavity 202. The front sparsity 230 and the rear sparsity 240 are located at the front and rear ends of the cavity 202, respectively. The rib structure 250 includes multiple ribs 252 spaced apart in the left-right direction. The two ends of each rib 252 are connected to the front sparsity 230 and the rear sparsity 240, respectively. The front sparsity 230, the rear sparsity 240, and two adjacent ribs 252 form the cavity wall of a mounting cavity 202a. The inlet / outlet 202b is located on the lower skin 220.

[0056] In this embodiment, the inlet / outlet 202b is located below the wing body 200. Thus, when installing or removing the battery pack 300, a trolley with a lifting function can be used. Specifically, when assembling the battery pack 300 on the wing body 200, the trolley first transports the battery pack 300 directly below the inlet / outlet 202b, then lifts the battery pack 300 and pushes it into the mounting cavity 202a through the inlet / outlet 202b, causing the first limiting part 412 and the second limiting part 422 to abut. After the first limiting part 412 and the second limiting part 422 are detachably connected, the lifting mechanism of the trolley is retracted. Finally, the inlet / outlet 202b is closed by the bag opening cover 222, completing the assembly of the battery pack 300 on the wing body 200. The disassembly sequence of the battery pack 300 is the reverse of the installation sequence, and will not be described in detail here. It is understood that in other embodiments, the inlet / outlet 202b may also be located above the wing body 200, in which case the battery pack 300 can be installed or removed using a hoisting device.

[0057] In this embodiment, the flap cover 222 is detachably connected to the lower skin 220 via bolts 222a. Thus, when the flap cover 222 is separated from the lower skin 220, the flap cover 222 can open the inlet / outlet 202b; and when the flap cover 222 is on the lower skin 220, the flap cover 222 can close the inlet / outlet 202b. It is understood that in other embodiments, the flap cover 222 may also be hinged to the lower skin 220 on one side and connected to the lower skin 220 on the other side via a lock; that is, the flap cover 222 may also be a door-like structure. In some embodiments, the wing body 200 has one inlet / outlet 202b and multiple mounting cavities 202a, with the multiple mounting cavities 202a communicating with the same inlet / outlet 202b. In this case, the flap cover 222 can be a single unit. In some embodiments, the wing body 200 has multiple inlets and outlets 202b and multiple mounting cavities 202a, with each inlet and outlet 202b and mounting cavity 202a being configured one-to-one. In this case, there can be one cover 222, with one cover 222 corresponding to multiple inlets and outlets 202b; or there can be multiple covers 222, with each cover 222 being configured one-to-one with multiple inlets and outlets 202b.

[0058] In this embodiment, the battery pack 300 has an outer shell. The front spar 230, rear spar 240, ribs 252, and the outer shell are made of carbon fiber composite material. The first limiting part 412 and the second limiting part 422 are made of aluminum alloy. This not only facilitates a secure connection between the battery pack 300 and the wing body 200, but also helps to reduce the weight of the wing structure 10.

[0059] In this embodiment, as Figure 1 , Figure 4 and Figure 5 As shown, each of the two ribs 252 of the mounting cavity 202a is provided with multiple (three) first limiting parts 412, that is, multiple (three) mounting connectors 410. Each of the two outer side walls of the battery pack 300 corresponding to the two ribs 252 of the mounting cavity 202a is provided with multiple (three) spaced-apart second limiting parts 422, that is, multiple (three) mounting sections 420. The multiple (three) first limiting parts 412 and the multiple (three) second limiting parts 422 are arranged one-to-one. This facilitates the connection between the battery pack 300 and the cavity wall of the mounting cavity 202a.

[0060] In this embodiment, as Figure 3As shown, the side of the battery pack 300 closest to the upper skin 210 is designated as the upper side 302. The side of the battery pack 300 closest to the lower skin 220 is designated as the lower side 304. The lower side 304 has a planar structure, while the upper side 302 has an irregular structure. Along the direction from the front spar 230 to the rear spar 240, the distance between the lower side 304 and the upper side 302 gradually decreases, so that the shape of the upper side 302 matches the shape of the upper skin 210. That is, in this embodiment, the battery pack 300 is specifically designed according to the airfoil of the wing body 200, making full use of the internal space of the wing body 200 and achieving effective utilization of the internal space of the wing body 200.

[0061] In this embodiment, the side of the battery pack 300 closest to the front spar 230 is designated as the front side 306. The side of the battery pack 300 closest to the rear spar 240 is designated as the rear side 308. The upper side 302 includes a first planar segment 302a, a second planar segment 302b, and a sloped segment 302c. The front side 306, the first planar segment 302a, the second planar segment 302b, the sloped segment 302c, and the rear side 308 are connected sequentially. This not only satisfies the configuration requirements of the battery pack 300 but also utilizes the internal space of the wing body 200, achieving effective utilization of the internal space of the wing body 200.
