Description

Technical Field

[0001] The present application belongs to the field of aircraft suspension structure design, and in particular relates to a lateral release deformation mechanism for an embedded suspension. Background Art

[0002] Since the embedded suspension is installed inside the fuselage, it will be affected by the deformation of the fuselage, especially the lateral expansion or compression deformation. In order to eliminate the influence of this deformation, the following methods are usually adopted: 1. Opening a lateral elliptical hole at the installation point. The advantage of this method is that it pays a small weight penalty. The disadvantage is that the amount of lateral deformation released by the elliptical hole opening is relatively limited, and an overly large elliptical hole will add a vertical bending moment, increase the load at the installation point, and also have an adverse effect on the load diffusion structure. In addition, the elliptical hole structure is bound to cause wear when the mounting bolts slide in the elliptical hole during each flight, which also has an adverse effect on the life of the suspension device; 2. Beam-type suspension device. The advantage of this device is that the force transmission path is clear, which is convenient for designing the load diffusion structure and releasing the lateral deformation through the geometric deformation of the structure. The disadvantage is that it is heavy and occupies a large space, which reduces the space utilization rate.

[0003] Therefore, it is desired to have a technical solution to overcome or at least alleviate at least one of the above-mentioned deficiencies of the prior art. Utility Model Content

Therefore, it should not be understood as limiting the scope of protection of this application.

[0028] The following is combined with Figure 1 This application is described in further detail.

[0029] The present application provides a lateral release deformation mechanism for an embedded suspension, comprising: a support, a pull rod and a suspension bracket 3.

[0030] Specifically, such as Figure 1As shown, there are four supports, namely a first support 1, a second support 4, a third support 5, and a fourth support 7; there are two pull rods, namely a first pull rod 2 and a second pull rod 6; and the hanger 3 is in an I-shape. The hanger 3 has an I-shaped main body and a first connecting end, a second connecting end, a third connecting end, and a fourth connecting end on the main body. The I-shaped main body is used to mount a hanging object. Among them, the first support 1, the second support 4, the third support 5, and the fourth support 7 are all fixedly mounted on the side wall of the buried cabin. The first support 1 and the fourth support 7 are located on the same side of the buried cabin side wall and are arranged at the same height. The second support 4 and the third support 5 are located on the same side of the buried cabin side wall and are arranged at the same height. One end of the first pull rod 2 is hinged to the first support 1, and the other end is hinged to the first connecting end of the hanger 3. One end of the second pull rod 6 is hinged to the fourth support 7, and the other end is hinged to the fourth connecting end of the hanger 3. The second connecting end of the hanger 3 is hinged to the second support 4, and the third connecting end is hinged to the third support 5. It can be understood that the positions of the first support 1 and the fourth support 7 and the second support 4 and the third support 5 in the height direction are adapted to the lengths of the first pull rod 2 and the second pull rod 6, so that the suspension frame 3 remains horizontal in the static state before the body is deformed.

[0031] In a preferred embodiment of the present application, the first support 1, the second support 4, the third support 5 and the fourth support 7 all include a mounting base and a double-ear joint on the mounting base, and the mounting base of each support is fixedly connected to the side wall of the embedded cabin by bolts.

[0032] In a preferred embodiment of the present application, a single-ear joint is provided at one end of the first pull rod 2 and a double-ear joint is provided at the other end of the second pull rod 6. The single-ear joint of the pull rod is hinged to the double-ear joint of the corresponding support through a pin.

[0033] In a preferred embodiment of the present application, the first, second, third and fourth connecting ends of the suspension bracket 3 all adopt single-ear joints. The double-ear joint of the pull rod is hinged to the corresponding single-ear joint of the suspension bracket 3 via a pin.

[0034] In a preferred embodiment of the present application, the first connecting end, the second connecting end, the third connecting end and the fourth connecting end of the hanger 3 all have predetermined angles with the I-shaped body of the hanger 3 .

[0035] It can be understood that the lateral deformation release mechanism of the embedded suspension of the present application is not limited to the above structure. The number of supports, pull rods and 3 connecting ends of the suspension frame can be appropriately selected. For example, 6 supports and 3 pull rods are used, and the suspension frame adopts a W-shaped structure. The design with 6 connecting ends can also achieve lateral deformation release.

[0036] The embedded suspension's lateral deformation release mechanism, described in this application, incorporates a small vertical tie rod on one side. This oscillation effectively releases lateral deformation of the embedded compartment's sidewall. Compared to methods using oblong holes in mounting brackets, the oscillation of the tie rod eliminates wear and tear, extending the lifespan of the entire suspension structure. Compared to beam-type suspension systems, this design significantly improves weight optimization and space utilization.

[0037] The embedded suspension lateral release deformation mechanism of the present application not only increases the life of the suspension structure, but also reduces the weight of the structure itself, while also improving the space utilization rate in the cabin. It has a simple structural form and low production cost.

[0038] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
