In order to facilitate the description, in the utility model, only the application of the aviation chair seat plate structure in the aviation chair is taken as an example for description, and the principle of the application of the aviation chair seat plate structure in other types of equipment is substantially the same as that in the aviation chair, which will not be described here.

[0029] Please refer to Figure 1 , Figure 1 Fig. 1 is a structural schematic view of the aviation chair seat plate structure in an embodiment of the utility model. The aviation chair seat plate structure comprises a support frame 100, a base plate 200 and an elastic telescopic rod 300. One end of the base plate 200 is pivotally connected to the support frame 100. The elastic telescopic rod 300 has a first sleeve 310 and a second sleeve 320 which are nested with each other. The end of the first sleeve 310 is hingedly connected to the back surface of the base plate 200. The end of the second sleeve 320 is close to the free end of the base plate 200 and is hingedly connected to the support frame 100. The elastic telescopic rod 300 has an elastic force for lifting the free end of the base plate 200.

[0030] In this embodiment, first, one end of the base plate 200 is pivotally connected to the support frame 100. The ends of the first sleeve 310 and the second sleeve 320 are respectively hingedly connected to the back surface of the base plate 200 and the support frame. The elastic telescopic rod 300 has an elastic force for lifting the free end of the base plate 200, thereby playing a buffering role and improving the comfort of the seat cushion. Since the end of the second sleeve 320 is close to the free end of the base plate 200, the included angle between the elastic telescopic rod 300 and the back surface of the base plate 200 is very small, the vertical span of the elastic telescopic rod 300 is reduced, and the space occupied by the elastic telescopic rod 300 is greatly reduced, thereby achieving the goal of installing the elastic structure for the seat cushion in a narrow space.

[0031] In some embodiments, the seat plate structure of the aircraft seat further comprises a support column 400, which is rotatably mounted on the support frame 100, and the second sleeve 320 is fixedly connected to the support column 400.

[0032] In the embodiment, the support column 400 is rotatably mounted on the support frame 100, and the second sleeve 320 is fixedly connected to the support column 400, so that the second sleeve 320 can rotate around the support column 400 relative to the support frame 100.

[0033] In some embodiments, the base plate 200 has a pressing portion 210, and the support column 400 presses against the pressing portion 210 to block the rotation of the base plate 200.

[0034] In the embodiment, the support column 400 not only serves as the rotation center of the second sleeve 320, but also serves as a limiting component for preventing the base plate 200 from being overturned. When the pressing portion 210 is pressed against the support column 400, the base plate 200 reaches a limit position where it cannot continue to rotate.

[0035] On the basis of the above-mentioned embodiments, in some embodiments, the pressing portion 210 is provided with a first guide groove 211, and the support column 400 has a first guide wheel 410 which is movably embedded in the first guide groove 211.

[0036] In the embodiment, since the pressing portion 210 and the support column 400 will slide slightly when they contact each other, the first guide wheel 410 on the outer periphery of the support column 400 is slidably arranged in the first guide groove 211. On the one hand, rolling friction can replace sliding friction to avoid wear of the contact surface between the pressing portion 210 and the support column 400. On the other hand, the first guide wheel 410 is partially embedded in the first guide groove 211, which also serves as a limiting component to improve the stability of the base plate 200.

[0037] In some embodiments, the base plate 200 is provided with a hollow portion 240 at the center thereof, and the base plate 200 has a support portion which is detachably arranged in the hollow portion 240. When the aircraft seat is in normal use, the support portion is arranged in the hollow portion 240 for passengers to sit on. When the aircraft seat needs to be maintained, the support portion can be detached so that the arms and tools of the maintenance personnel can pass through the hollow portion 240, thereby providing the maintenance personnel with more operating space and improving the convenience of maintenance work.

[0038] Specifically, the support portion is a tight fabric support plate which is used to support passengers. Since the fabric support plate has a certain elasticity, the comfort of passengers can be improved.

[0039] In some embodiments, the second sleeve 320 and the support column 400 are detachably connected.

[0040] In the embodiment, when the substrate 200 needs to be turned over greatly for maintenance, the second sleeve 320 can be detached from the support column 400 to avoid the elastic telescopic rod 300 from hindering the turning over of the substrate 200.

[0041] Referring to Figure 2 In some embodiments, the substrate 200 is provided with a receiving groove 220 on the back surface, and the first sleeve 310 and the second sleeve 320 can be received in the receiving groove 220.

[0042] In the embodiment, since the first sleeve 310 and the second sleeve 320 can be received in the receiving groove 220, the vertical spaces occupied by the substrate 200 and the elastic telescopic rod 300 overlap with each other, and the space utilization is further improved.

[0043] On the basis of the above-mentioned embodiments, in some embodiments, the receiving groove 220 is provided with a rotating pin 221, and the first sleeve 310 is rotatably connected to the rotating pin 221.

[0044] Referring to Figure 2 and Figure 3 In some embodiments, the substrate 200 is provided with a guide pin 230, and the support frame 100 is provided with a second guide groove 110, and the guide pin 230 can slide along the second guide groove 110 to limit the rotation range of the substrate 200.

[0045] In the embodiment, since the guide pin 230 can slide along the second guide groove 110, the turning over angle of the substrate 200 is limited, and the turning over angle of the substrate 200 is prevented from being too large to affect the comfort of passengers.

[0046] In some embodiments, the guide pin 230 is provided with a second guide wheel 231 around the outer periphery, and the second guide wheel 231 can roll along the second guide groove 110.

[0047] In the embodiment, since the guide pin 230 is provided with the second guide wheel 231 around the outer periphery, the resistance of the guide pin 230 moving along the second guide groove 110 is reduced.

[0048] In some embodiments, the elastic telescopic rod 300 is a pneumatic spring.

[0049] In the embodiment, the pneumatic spring is a standard part with multiple specifications, which can be used as a preferred embodiment of the elastic telescopic rod 300.

[0050] In order to better understand the utility model, the following will be combined with Figures 1 to 3 The technical scheme of the utility model will be described in detail:

[0051] First, one end of the substrate 200 is pivoted to the support frame 100, the end of the first sleeve 310 and the second sleeve 320 are respectively hinged to the back of the substrate 200 and the support frame, the guide pin 230 can slide along the second guide slot 110, thereby limiting the turning angle of the substrate 200, avoiding the turning angle of the substrate 200 being too large, and the elastic telescopic rod 300 has the elastic force of lifting the free end of the substrate 200, thereby playing a buffering role and improving the comfort of the cushion. Since the end of the second sleeve 320 is close to the free end of the substrate 200, the included angle between the elastic telescopic rod 300 and the back of the substrate 200 is very small, the vertical span of the elastic telescopic rod 300 is reduced, and the space occupied by the elastic telescopic rod 300 is greatly reduced. Since the first sleeve 310 and the second sleeve 320 can be accommodated in the accommodating groove 220, the vertical space occupied by the substrate 200 and the elastic telescopic rod 300 overlaps each other, further improving the space utilization. Thus, the goal of installing an elastic structure for the cushion in a small space is achieved.

[0052] The specific embodiments of the utility model described above do not constitute a limitation on the scope of protection of the utility model. Any various other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
