Description

Technical Field

[0001] This utility model relates to the field of aerospace technology, and more specifically, to a lug connector. Furthermore, this utility model also relates to an aviation device including the aforementioned lug connector. Background Technology

[0002] With the development of technology, airplanes have become a rigid infrastructure for global spatial and temporal connectivity: their transportation speed is 30 to 50 times faster than sea freight, accounting for 54% of international passenger trips and 35% of the value of time-sensitive goods; in public health and disaster relief, air logistics can deliver emergency supplies to 90% of the world's population within 48 hours; the aviation industry itself contributes 3.5% to global GDP and directly drives high-value industrial chains such as tourism, manufacturing, and electronics.

[0003] Aircraft fuselage structures typically consist of longitudinal and transverse frames and panels. The cross-sectional shapes of longitudinal and transverse frame components are generally I-shaped and P-shaped. For P-shaped longitudinal and transverse frames requiring design separation surfaces, matching joints are necessary. For the inner and outer wing connections that need to transmit large bending moments, due to the limited airfoil height, multiple sets of horizontal or vertical lug joints are usually used. However, this results in numerous mating surfaces, making assembly and disassembly difficult and time-consuming, which cannot meet the rapid reassembly requirements of aircraft equipment on the battlefield. Furthermore, conventional P-shaped beams are prone to problems such as low joint structure efficiency and uneven distribution of joint stud loads.

[0004] In conclusion, how to reduce the difficulty of disassembling and assembling the lug connector and improve the efficiency of disassembly and assembly is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The core of this utility model is to provide an ear-shaped connector. The single-ear connector and the double-ear connector are detachably connected by a fixing member, which can reduce the difficulty of disassembling and assembling the ear-shaped connector and improve the disassembly and assembly efficiency. The setting of the single-ear transition web and the double-ear transition web can make the ear-shaped connector be evenly loaded.

[0031] Another core aspect of this invention is to provide an aviation device that includes the aforementioned ear-shaped connector.

[0032] It should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the purpose of facilitating the description of this application and simplifying the description. It is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0033] This application provides an ear-shaped connector, comprising: a single-ear connector 1, a single-ear connector base, a double-ear connector 4, a double-ear connector base and a fixing member;

[0034] Among them, the single-ear connector 1 is a plate-shaped structure, and the single-ear connector 1 is provided with a through hole 2;

[0035] The single-ear connector base is connected to the single-ear connector 1 via the single-ear transition web 3;

[0036] The double-ear connector 4 is provided with a through hole 5, which is corresponding to the through hole 2;

[0037] The double-ear connector base is connected to the double-ear connector 4 via the double-ear transition web 6;

[0038] The fastener is provided through the through hole 2 and the through hole 5. The fastener is used to realize the detachable connection between the single ear connector 1 and the double ear connector 4.

[0039] Specifically, the structures of the single-ear connector 1 and the double-ear connector 4 can be found in the attached diagram. Figure 1 The single-ear connector 1 is a plate-like structure with through holes 2 penetrating both ends on its surface. The double-ear connector 4 has through holes 5 corresponding to the through holes 2. Fixing components are installed in the through holes 2 and through holes 5. The fixing components enable the single-ear connector 1 and the double-ear connector 4 to be detachably connected, thereby reducing the difficulty of disassembling and assembling the ear-plate connector and improving the efficiency of disassembly and assembly. The single-ear connector 1 is connected to the single-ear connector base through a single-ear transition web 3, and the double-ear connector 4 is connected to the double-ear connector base through a double-ear transition web 6. The single-ear transition web 3 and the double-ear transition web 6 are plate-like structures, and their lengths can be determined according to the shear stress of the load on the web transferred to the flange being less than the allowable shear stress of the material. In other words, by setting the single-ear transition web 3 and the double-ear transition web 6 in the cross-sectional configuration, a symmetrical ear-plate connector and an asymmetrical п-shaped beam are formed, so that the ear plates are evenly loaded and stress concentration is avoided.

[0040] Based on the above embodiments, the double-ear connector 4 is a U-shaped piece, and both ends of the double-ear connector 4 are sheet-like structures. The distance between the two ends of the double-ear connector 4 is equal to the thickness of the single-ear connector 1.

[0041] Specifically, the two ends of the double-ear connector 4 are parallel plate-like structures, and the distance between the two ends of the double-ear connector 4 should be the same as the thickness of the single-ear connector 1, so that when the single-ear connector 1 is inserted between the two ends of the double-ear connector 4, the inner wall between the two ends of the double-ear connector 4 is completely fitted with the single-ear connector 1, and there is no gap between the single-ear connector 1 and the double-ear connector 4, so as to ensure the stability of the structure. In addition, when the single-ear connector 1 is inserted into the double-ear connector 4, the relative position of the through hole 2 and the through hole 5 should be fixed when they are aligned. The through hole 2 and the through hole 5 are preferably round holes, and the diameters of the two holes are the same. Generally speaking, the fasteners are usually bolts and steel bushings. The outer diameter of the thread section of the bolt should be slightly smaller than the diameter of the through hole 2 and the through hole 5, so as to facilitate the bolt insertion into the through hole 2 and the through hole 5, and not seriously affect the structural reliability of the single-ear connector 1 and the double-ear connector 4 in the connection state.

[0042] Based on the above embodiment, the two ends of the double-ear connector 4 are respectively provided with two through holes 5, and the single-ear connector 1 is provided with two through holes 2. The distance between the two through holes 5 is the same as the distance between the two through holes 2.

[0043] Specifically, each end of the double-ear connector 4 is provided with two through holes 5, which are arranged along the length of the end of the double-ear connector 4. Similarly, the two through holes 2 on the single-ear connector 1 are provided corresponding to the two through holes 5. The relative positional relationship of the two through holes 5 can be referred to the appendix. Figure 2 It should be noted that the distance between the two through holes 5 and the through hole 2 should be relatively increased. When the height of the lug is limited, the lug hole spacing is increased by lengthening the span, thereby increasing the bending moment arm and reducing the intersection load.

[0044] Based on the above embodiments, the single-ear connector base includes two single-ear connector flanges 7 perpendicular to the single-ear connector 1, and the two single-ear connector flanges 7 are arranged parallel to each other. The double-ear connector base includes two double-ear connector flanges 8 perpendicular to the double-ear connector 4, and the two double-ear connector flanges 8 are arranged parallel to each other.

[0045] Specifically, there are two single-ear connector flange strips 7, and the two single-ear connector flange strips 7 are parallel to each other. Please refer to the attached document. Figure 2Two single-ear joint flanges 7 are set vertically, and a single-ear joint 1 is set horizontally. Both ends of the single-ear joint 1 are fixedly connected to the two single-ear joint flanges 7 respectively. The setting of the double-ear joint flange 8 corresponds to the setting of the single-ear joint flange 7, and will not be described again. The single-ear joint flange 7 and the double-ear joint flange 8 are usually connected to the beam flange by fasteners to transfer the intersection load to the beam structure.

[0046] In addition, the single-ear transition web 3 and the double-ear transition web 6 are one of the key features of this application, which can make the ear plate load evenly distributed to the upper and lower flanges of the π-shaped joint, avoiding the stress concentration of the flanges caused by the load of conventional eccentric ear plate joints.

[0047] Based on the above embodiment, a single-ear connector web 9 is provided between the two single-ear connector flanges 7, the single-ear connector flange 7 is perpendicular to and connected to the single-ear connector web 9, and a double-ear connector web 10 is provided between the double-ear connector flanges 8, the double-ear connector flange 8 is perpendicular to and connected to the double-ear connector web 10.

[0048] Specifically, the single-eared joint web 9 is parallel to the single-eared joint 1, and the double-eared joint web 10 is parallel to the double-eared joint 4. The single-eared joint web 9 and the double-eared joint web 10 are usually connected to the beam web by fasteners to realize the transfer of load, or it can be said to be used for the diffusion of intersection load.

[0049] Based on the above embodiments, a single-ear transition web end plate 11 is provided between the single-ear connector web plate 9 and the two single-ear connector flanges 7. The single-ear transition web end plate 11 is perpendicular to the single-ear connector web plate 9 and the two single-ear connector flanges 7. A double-ear transition web end plate 12 is provided between the double-ear connector web plate 10 and the two double-ear connector flanges 8 supports. The double-ear transition web end plate 12 is perpendicular to the double-ear connector web plate 10 and the two double-ear connector flanges 8.

[0050] Specifically, the single-ear transition web end plate 11 is directly connected to the single-ear connector 1, and the double-ear transition web end plate 12 is directly connected to the double-ear connector 4. The single-ear transition web end plate 11, the double-ear transition web end plate 12, the single-ear connector web plate 9, and the double-ear connector web plate 10 are used together to maintain the stability of the connector structure while transmitting loads.

[0051] Based on the above embodiments, the single-ear connector 1 and the double-ear connector 4 are arranged opposite to each other, and the end of the single-ear connector 1 facing away from the single-ear transition web end plate 11 is an arc-shaped end, and the end of the double-ear connector 4 facing away from the double-ear transition web end plate 12 is also an arc-shaped end.

[0052] For details, please refer to the appendix. Figure 1The right end of the single-ear connector 1 and the left end of the double-ear connector 4 are both arc-shaped ends. The arc-shaped ends make it easier to insert the single-ear connector 1 between the two ends of the double-ear connector 4, or in other words, it makes it easier to insert the two ends of the double-ear connector 4 between the two single-ear connector flanges 7, thereby improving the efficiency of disassembly and assembly.

[0053] Based on the above embodiment, the size of the double-ear connector 4 gradually decreases in the direction toward the arc-shaped end.

[0054] Specifically, the structure of the dual-ear connector 4 can be found in the attached document. Figure 1 The size of the double-ear connector 4 gradually decreases from right to left. The double-ear connector flanges 8 at both ends are connected to the double-ear connector 4 along the side ends of the double-ear connector 4, so that the double-ear connector 4 can be inserted more smoothly between the two single-ear connector flanges 7, reducing the difficulty of disassembly and assembly and improving the efficiency of disassembly and assembly.

[0055] Based on the above embodiment, two through holes 2 are respectively provided at both ends of the single-ear connector 1, and two through holes 5 are respectively provided at both ends of the double-ear connector 4.

[0056] For details, please refer to the appendix. Figure 2 The distance between the two through holes 5 and the distance between the two through holes 2 are the same, both being X. When the height of the lug is limited, the value of X is increased by lengthening the span, thereby increasing the bending moment arm and reducing the load at the intersection.

[0057] In addition to the aforementioned ear connector, this utility model also provides an aviation device including the ear connector disclosed in the above embodiments. For the structure of other parts of the aviation device, please refer to the prior art, which will not be repeated here.

[0058] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0059] The above provides a detailed description of the lug connector and aviation equipment provided by this utility model.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
