[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] To address the technical problem of unsmooth seat position adjustment on known aircraft, this application provides a sliding adjustment mechanism, a seat, and flight equipment that can improve the smoothness of seat adjustment.

[0027] It should be noted that the seat in this application is used in, but not limited to, flight equipment. For ease of explanation, this application only uses the application of the seat in flight equipment as an example. The principle of the seat in other types of passenger equipment is essentially the same as that in flight equipment, and will not be elaborated here. The flight equipment can be a low-altitude aircraft, such as an electric vertical takeoff and landing aircraft.

[0028] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of flight equipment 10 in one embodiment of this application. The flight equipment includes a frame 200 and a seat 100. The seat 100 is disposed on the frame 200. The seat 100 can be used for passengers or other occupants.

[0029] See Figures 1 to 3 The seat 100 includes a seat frame 110 and a seat body 120. The seat frame 110 is connected to the frame 200. The seat frame 110 can be made of composite materials such as aluminum alloy and titanium alloy, which has the advantages of being lightweight and having high strength, meeting the lightweight requirements of flight equipment 10 such as low-altitude aircraft, while providing stable and reliable support. The seat frame 110 can be fixedly connected to the frame 200 or movably connected to the frame 200. The seat body 120 is located on the seat frame 110. The seat frame 110 provides support for the seat body 120. The seat body 120 is used for occupants to sit on.

[0030] See Figure 1 and Figure 2 The seat 100 also includes a life jacket pocket 141 and a headrest 142. The life jacket pocket 141 is located on the underside of the seat body 120. The headrest 142 is connected to the seat body 120. The seat body 120 has a boarding handle 143 on one side along its width, and a first hook 144 on the other side along its width. The first hook 144 can be used to hang everyday items such as headphones. A second hook 145 is located at the upper end of the seat body 120. The second hook 145 can be used to hang clothing, hats, etc.

[0031] In this embodiment, see Figures 1 to 7The seat 100 also includes a sliding adjustment mechanism 130. The sliding adjustment mechanism 130 includes an adjusting member 131, a rolling member 132, and / or a friction-reducing member 133. The adjusting member 131 is connected at one end to the seat frame 110, and the other end is slidably disposed within a groove 310. The rolling member 132 is connected to the adjusting member 131, located in the groove 310, and is used for sliding engagement with the groove surface of the groove 310. The friction-reducing member 133 is connected to the adjusting member 131, located in the groove 310, and the adjusting member 131 is used to contact the groove surface of the groove 310.

[0032] Thus, by rolling the rolling element 132 in cooperation with the groove surface of the slide 310, the friction between the seat frame 110 and the adjusting element 131 is reduced, enabling smooth adjustment of the seat frame 110 relative to the guide rail 300. Simultaneously, the rolling element 132 can also bear the load of the seat frame 110, improving the overall reliability of the seat 100. The friction-reducing element 133 reduces the friction between the guide rail 300 and the adjusting element 131, provides auxiliary lubrication, and exhibits minimal wear even after long-term use, improving application reliability. Furthermore, the friction-reducing element 133 can fill the assembly gap between the adjusting element 131 and the slide 310, ensuring reliable contact between the rolling element 132 and the guide rail 300.

[0033] In addition, the rolling element 132 and the friction-reducing element 133 are both located in the groove 310, which can provide better protection for both, reduce the possibility of them being affected by foreign objects, and improve the reliability of use.

[0034] It is understood that the sliding adjustment mechanism 130 of this embodiment can also be installed between the seat frame 110 and the seat body 120 to realize the seat height adjustment of the seat 100.

[0035] In one embodiment, see Figure 3 and Figure 4 The flight equipment 10 also includes a guide rail 300. The guide rail 300 is fixedly mounted on the frame 200. The guide rail 300 extends along a second direction X2. The guide rail 300 has a groove 310 extending along the second direction X2. The groove 310 can guide and limit the seat frame 110, reduce the degree of freedom of the seat frame 110, and improve the reliability of the seat frame 110 when stationary.

[0036] In one embodiment, the flight device 10 further includes a locking member 400. The locking member 400 is disposed within the slide groove 310 and passes through the guide rail 300, connecting to the frame 200. The locking member 400 may specifically be a bolt. In other embodiments, the guide rail 300 and the frame 200 may also be fixedly connected by welding.

[0037] In one embodiment, see Figures 3 to 6 The rolling element 132 is located on the side of the adjusting element 131 facing the bottom surface of the groove 310, and the rolling element 132 rolls in contact with the bottom surface of the groove 310. The friction reducing element 133 is used to contact the groove surface of the groove 310.

[0038] In one embodiment, the slide 310 has an opening 320. The frame 200 has a protruding stop 330 at the opening 320. The adjusting member 131 passes through the stop 330 along one side of the first direction X1 and is connected to the seat frame 110. The seat 100 also includes a rolling member 132 and a friction damping member 133. The rolling member 132 is disposed on the bottom surface of the adjusting member 131 and rolls with the bottom surface of the slide 310. The friction damping member 133 is disposed on the side surface of the adjusting member 131 and contacts the side surface of the slide 310 and the stop 330.

[0039] Thus, through the synergistic effect of the rolling element 132 and the friction-reducing element 133, the smoothness of sliding between the guide rail 300 and the adjusting element 131 can be significantly improved. Furthermore, the stop portion 330 ensures the limiting effect on the adjusting element 131, reducing the possibility of the adjusting element 131 dislodging from the opening 320 into the groove 310. By having the friction-reducing element 133 contact the stop portion 330, the friction between the adjusting element 131 and the guide rail 300 on both sides in its thickness direction is reduced, thereby mitigating the risk of jamming. In other embodiments, the adjusting element 131 may also be provided with multiple rolling elements 132. The adjusting element 131 and the stop portion 330 may also roll together via additional rolling elements 132. The adjusting element 131 may also be provided with multiple friction-reducing elements 133. The adjusting element 131 may contact the bottom surface of the groove 310 via additional friction-reducing elements 133.

[0040] In one embodiment, see Figure 5 and Figure 6 The rolling element 132 includes a rolling frame 1321 and multiple rollers 1322. The rolling frame 1321 is connected to the adjusting element 131. The rollers 1322 are rotatably mounted on the rolling frame 1321 around a rolling axis 1323. The rolling axis 1323 intersects the length direction of the slide groove 310, and the rollers 1322 are tangent to the bottom surface of the slide groove 310. Thus, when the adjusting element 131 moves along the length direction of the slide groove 310, the multiple rollers 1322 roll around the rolling axis 1323 and remain tangent to the bottom surface of the slide groove 310, thereby significantly reducing the friction between the adjusting element 131 and the slide groove 310.

[0041] Specifically, roller 1322 can be configured as a cylindrical roller bearing. In other embodiments, roller 1322 can also be configured as a spherical roller bearing.

[0042] In one embodiment, see Figure 5and Figure 6 The adjusting member 131 has a first connecting portion 1311 on the side facing the opening of the slide groove 310. The rolling member 132 has a second connecting portion 1324 at one end along its length direction, and the second connecting portion 1324 is connected to the first connecting portion 1311.

[0043] In one embodiment, see Figure 5 and Figure 6 The first connecting portion 1311 includes a connecting post 13111, which protrudes towards the opening of the slide groove 310. The second connecting portion 1324 includes a first connecting wall 13241 and a second connecting wall 13242. The first connecting wall 13241 extends towards the opening of the slide groove 310, and the second connecting wall 13242 is bent to connect with the first connecting wall 13241. The second connecting wall 13242 has a first insertion hole 13243, into which the connecting post 13111 is inserted. In this way, the cooperation between the connecting post 13111 and the first insertion hole 13243 can make full use of the open space of the slide groove 310, thereby reducing the use of screws and bolts, reducing the space occupied by the rolling element 132 along the groove depth of the slide groove 310, and improving versatility. In other embodiments, the first connecting part 1311 and the second connecting part 1324 may also be configured as a countersunk hole and a countersunk screw, or the rolling frame 1321 and the adjusting member 131 may be fixed by welding.

[0044] Optionally, see Figure 6 The rolling frame 1321 has multiple rolling grooves 13211. Each roller 1322 is rotatably disposed in one of the rolling grooves 13211. A second insertion hole 13244 is formed at the end of the first connecting wall 13241 opposite to the second connecting wall 13242. The end of the first connecting wall 13241 opposite to the second connecting wall 13242 extends into the rolling groove 13211 at one end of the rolling frame 1321, and the second insertion hole 13244 is inserted into the bottom surface of the rolling frame 1321. In this way, the second connecting part 1324 and the rolling element 132 are reliably fixed.

[0045] In this embodiment, see Figure 5 and Figure 6 The friction reducing component 133 includes two contact walls 1331. The two contact walls 1331 are respectively connected to both sides of the adjusting component 131 along its width direction, and the two contact walls 1331 respectively contact the groove sides of the slide groove 310 along its width direction.

[0046] In one embodiment, the friction reducing member 133 further includes a top wall 1332, which is connected to the contact wall 1331 and contacts the stop portion 330. Thus, the top wall 1332 and the contact wall 1331 are respectively connected to the groove side of the slide groove 310 and the stop portion 330.

[0047] The connecting post 13111 can pass through the top wall 1332 to be inserted into the first socket 13243.

[0048] Specifically, the contact wall 1331 can also be constructed as an enclosure. The friction-reducing component 133 is integrally fitted onto the adjusting component 131, which can improve the ease of assembly.

[0049] In this embodiment, see Figure 3 and Figure 4 The seat 100 also includes a locking member 134. The locking member 134 has a second locking position and a second releasing position. When the locking member 134 is in the second locking position, the locking member 134 locks the adjusting member 131 to the frame 200. When the locking member 134 is in the second releasing position, the locking member 134 allows the adjusting member 131 to move relative to the frame 200.

[0050] In one embodiment, there are two guide rails 300. The two guide rails 300 are spaced apart along a third direction X3. The seat frame 110 includes two chair legs 111. The two chair legs 111 are spaced apart along a third direction X3.

[0051] In one embodiment, the chair leg 111 includes a first leg 1111 and a second leg 1112. The first leg 1111 is used to connect to the seat body 120 and extends along a first direction X1. The second leg 1112 extends along a second direction X2 and connects to the first leg 1111. Multiple adjusting members 131 are provided. Each second leg 1112 of each chair leg 111 is provided with multiple adjusting members 131. The multiple adjusting members 131 are spaced apart along the length direction of the second leg 1112. This facilitates stable position adjustment of the second leg 1112.

[0052] In each chair leg 111, a locking element 134 is provided at one of the adjusting members 131. In other embodiments, a corresponding locking element 134 may be provided at each adjusting member 131.

[0053] In this embodiment, see Figure 4 The guide rail 300 has multiple limiting ports 340 formed in the open opening 320, and the multiple limiting ports 340 are spaced apart along the second direction X2. When the locking member 134 is in the second locking position, one end of the locking member 134 is inserted into the adjusting member 131, and the locking member 134 is selectively inserted into one of the limiting ports 340; when the locking member 134 is in the second unlocking position, the locking member 134 and the adjusting member 131 are spaced apart, and the locking member 134 is located outside the limiting port 340.

[0054] In one embodiment, the guide rail 300 also has a plurality of mounting holes 350 at the opening 320. The adjusting member 131 can be inserted into the slide groove 310 through the mounting holes 350, and when it moves along the second direction X2 to a plurality of limiting ports 340, it can be locked or released by the locking member 134 cooperating with one of the limiting ports 340.

[0055] In one embodiment, the seat 100 further includes a connector 135. The connector 135 connects to one side of the adjusting member 131 extending out of the slide groove 310, and the connector 135 has a guide hole 1351 extending through the connector 135. A locking member 134 is movably disposed in the guide hole 1351.

[0056] In one embodiment, see Figure 7 The locking member 134 includes a positioning block 1341, a connecting block 1342, an elastic part 1343, a lifting part 1344, and an anti-wear sleeve 1345. The anti-wear sleeve 1345 is located at one end of the guide hole 1351. The connecting block 1342 is movably located at the other end of the guide hole 1351. The lifting part 1344 passes through the anti-wear sleeve 1345 and connects to the connecting block 1342. The positioning block 1341 is located on the side of the connecting member 135 facing the guide rail 300. The positioning block 1341 is connected to the connecting block 1342. The positioning block 1341 is used to cooperate with the limiting port 340, and the positioning block 1341 is also used to insert into the adjusting member 131. The elastic part 1343 is elastically supported between the anti-wear sleeve 1345 and the connecting block 1342. The elastic part 1343 applies an elastic force to the connecting block 1342 so that the positioning block 1341 can remain engaged with the limiting port 340 and the adjusting member 131. Thus, the anti-wear sleeve 1345 protects the lifting part 1344. The elastic part 1343 ensures that the position of the adjusting member 131 remains fixed when the occupant is not operating the lifting part 1344, ensuring the reliable fixation of the seat frame 110.

[0057] The lifting part 1344 can be constructed as a steel cable, and the connecting block 1342 can be provided with two staggered figure-eight holes to ensure that the lifting part 1344 can extend into the connecting block 1342 and be fixed to the connecting block 1342, thereby driving the connecting block 1342 to overcome the elastic force of the elastic part 1343, causing the locking member 134 to disengage from the limiting port 340 and separate from the adjusting member 131, so that the occupant can adjust the seat frame 110 along the length direction of the slide groove 310.

[0058] In one embodiment, please refer again. Figure 1 The seat 100 also includes an adjustment handle 146. The adjustment handle 146 is located on the lower side of the seat body 120. The adjustment handle 146 is connected to the lifting part 1344, and the occupant can control the adjustment member 131 to switch between the second unlocked position and the second locked position by controlling the adjustment handle 146.

[0059] In one embodiment, see Figure 7 The bottom surface of the positioning block 1341 has a positioning groove 13411. The top surface of the adjusting member 131 has a positioning protrusion 1312. When the locking member 134 is in the second locking position, the positioning protrusion 1312 is inserted into the positioning groove 13411 to limit the locking member 134 and the adjusting member 131 along the second direction X2. This, in conjunction with the sliding groove 310, ensures the fixation of the seat frame 110.

[0060] Specifically, see Figure 4 The connector 135 is inserted into the second leg 1112 and connected to the second leg 1112 by the first fastener 36.

[0061] In one embodiment, see Figure 7 The top of the adjusting member 131 has a protruding fixing block 1313. The connecting member 135 has a fixing groove 1352. The fixing block 1313 extends into the fixing groove 1352. The fixing block 1313 is connected to the connecting member 135 by a second fastener 1346. The second fastener 1346 can be configured as a bolt to facilitate the assembly and disassembly of the adjusting member 131 and the connecting member 135.

[0062] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
