[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 seat and flight equipment with seat height adjustment function, which can improve the smoothness of seat adjustment.

[0027] It should be noted that the seat with height adjustment function in this application is used in, but not limited to, flight equipment. For ease of explanation, this application only uses the application of a seat with height adjustment function in flight equipment as an example. The principle of applying a seat with height adjustment function 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 (eVTOL) 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 with adjustable height. The seat 100 with adjustable height is disposed on the frame 200. The seat 100 with adjustable height can be used by passengers or other occupants.

[0029] See Figure 1 and Figure 2 The seat 100 with adjustable seat height 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 with height adjustment also includes a life jacket pocket 161 and a headrest 162. The life jacket pocket 161 is located on the underside of the seat body 120. The headrest 162 is connected to the seat body 120. The seat body 120 has a boarding handle 163 on one side along its width, and a first hook 164 on the other side along its width. The first hook 164 can be used to hang everyday items such as headphones. A second hook 165 is located at the upper end of the seat body 120. The second hook 165 can be used to hang clothing, hats, etc.

[0031] For ease of description, this embodiment defines a first direction X1, a second direction X2, and a third direction X3. The first direction X1 is generally parallel to the vertical direction, and the seat body 120 is movably disposed on the seat frame 110 along the first direction X1. The second direction X2 is generally parallel to the forward direction of the flight equipment 10. The third direction X3 is generally parallel to the width direction of the seat 100 with height adjustment function.

[0032] In one embodiment, see Figure 2 and Figure 3 The seat body 120 includes a seat plate 121 and a backrest 122. The seat plate 121 and the backrest 122 can be configured as a relatively fixed structure. In one embodiment, see [reference needed]. Figure 3 and Figure 4The seat body 120 also includes an adjuster 130. The adjuster 130 includes a first connecting plate 131, a second connecting plate 132, and a rotating part 133. One end of the first connecting plate 131 is connected to the backrest 122, and the other end of the first connecting plate 131 is rotatably connected to one end of the second connecting plate 132 via the rotating part 133. The other end of the second connecting plate 132 is connected to the seat plate 121. The tilt angle of the backrest 122 can be adjusted using the adjuster 130.

[0033] Optionally, the angle adjuster 130 further includes a first fastener 134 and a second fastener 135. The first fastener 134 secures the first connecting plate 131 to the backrest 122. The second fastener 135 connects the second connecting plate 132 to the seat plate 121.

[0034] In this embodiment, see Figures 4 to 6 The seat 100 with height adjustment function further includes an adjusting member 141, a rolling member 142, and / or a friction-reducing member 143. One end of the adjusting member 141 is connected to the seat frame 110. The seat body 120 is connected to the other end of the adjusting member 141, and the seat body 120 moves relative to the seat frame 110 along a first direction X1 via the adjusting member 141. The rolling member 142 is disposed on the adjusting member 141, and the rolling member 142 rolls in engagement with one of the seat frame 110 or the seat body 120; the friction-reducing member 143 is disposed on the adjusting member 141, and the friction-reducing member 143 contacts the seat frame 110 or the seat body 120.

[0035] Thus, by rolling contacting the seat frame 110 or seat body 120, the rolling element 142 reduces the friction between the seat frame 110 and the adjusting element 141, enabling smooth adjustment of the seat body 120 relative to the seat frame 110. Simultaneously, the rolling element 142 can also bear part of the load on the seat body 120, improving the overall reliability of the seat 100 with height adjustment function. The friction-reducing element 143 reduces the friction between the seat frame 110 and the adjusting element 141, provides auxiliary lubrication, and exhibits minimal wear even after long-term use, improving application reliability.

[0036] In this embodiment, see Figure 4 and Figure 5 The seat frame 110 has a sliding groove 111. The sliding groove 111 extends along a first direction X1, and one end of the adjusting member 141 is slidably disposed in the sliding groove 111 along the first direction X1, while the other end of the adjusting member 141 is connected to the seat body 120. See also... Figure 6 and Figure 7 The rolling element 142 rolls into contact with the groove surface of the slide groove 111. The friction-reducing element 143 contacts the groove surface of the slide groove 111.

[0037] Thus, the slide groove 111 allows the adjusting member 141 to have only one degree of freedom in the first direction X1, thereby enabling accurate adjustment of the seat body 120 along the first direction X1. The rolling member 142 and the friction-reducing member 143 are both located within the slide groove 111, providing better protection for both and reducing the possibility of them being affected by foreign objects, thus improving reliability. Furthermore, the friction-reducing member 143 can fill the assembly gap between the adjusting member 141 and the slide groove 111, ensuring reliable contact between the rolling member 142 and the seat frame 110.

[0038] Understandably, the friction-reducing component 143 can be made of wear-resistant materials.

[0039] Optionally, see Figure 5 A first limiting portion 1131 is formed at the end of the slide groove 111 opposite to the seat body 120 along the first direction X1. The first limiting portion 1131 protrudes along the bottom surface of the slide groove 111 to limit the adjusting member 141. The first limiting portion 1131 limits the end of the adjusting member 141 opposite to the seat body 120 along the first direction X1 to prevent the seat body 120 from falling downward along the first direction X1. A second limiting portion 1132 is formed at the opening of the slide groove 111 on the seat frame 110. The second limiting portion 1132 protrudes along the surface of the seat frame 110. The second limiting portion 1132 can cooperate with the first extension portion 1412 to limit the adjusting member 141 from extending out of the slide groove 111.

[0040] In one embodiment, see Figure 5 The slide groove 111 has an opening 1111, and the seat frame 110 has a protruding stop 112 at the opening 1111. The adjusting member 141 passes through the stop 112 along the third direction X3 and connects to the seat body 120. See also: Figure 6 and Figure 7 The seat 100 with height adjustment function also includes a rolling element 142 and a friction damping element 143. The rolling element 142 is disposed on the bottom surface of the adjusting element 141 and rolls with the bottom surface of the groove 111. The friction damping element 143 is disposed on the side of the adjusting element 141 and contacts the side surface of the groove 111 and the stop part 112.

[0041] Thus, through the synergistic effect of the rolling element 142 and the friction-reducing element 143, the smoothness of sliding between the seat frame 110 and the adjusting element 141 can be significantly improved. Furthermore, the stop portion 112 ensures the limiting effect on the adjusting element 141, reducing the possibility of the adjusting element 141 dislodging from the opening 1111 into the groove 111. By having the friction-reducing element 143 contact the stop portion 112, the friction between the adjusting element 141 and the seat frame 110 on both sides in its thickness direction is reduced, thereby mitigating the risk of jamming. In other embodiments, the adjusting element 141 may also be provided with multiple rolling elements 142. The adjusting element 141 and the stop portion 112 may also roll together via additional rolling elements 142. The adjusting element 141 may also be provided with multiple friction-reducing elements 143. The adjusting element 141 may contact the bottom surface of the groove 111 via additional friction-reducing elements 143.

[0042] In one embodiment, see Figure 5 Along the width direction of the slide groove 111, the first extension 1412 extends along one side of the third direction X3 and connects to the seat body 120. The adjusting member 141 also includes a second extension 1413. The second extension 1413 extends along the other side of the third direction X3, and the projection of the second extension 1413 along the second direction X2 is located on the seat frame 110. Through the cooperation of the first extension 1412 and the second extension 1413, they can cooperate with the movable part 1411 in the depth direction of the slide groove 111 (i.e., the second direction X2), respectively serving to clamp the two stop parts 112 on both sides of the width direction of the slide groove 111, thereby improving the movement reliability of the adjusting member 141.

[0043] In one embodiment, see Figure 6 and Figure 7 The rolling element 142 includes a rolling frame 1421 and multiple rollers 1422. The rolling frame 1421 is connected to the adjusting element 141. The rollers 1422 are rotatably mounted on the rolling frame 1421 around a rolling axis 1423. The rolling axis 1423 intersects the length direction of the slide groove 111, and the rollers 1422 are tangent to the bottom surface of the slide groove 111. Thus, when the adjusting element 141 moves along the length direction of the slide groove 111, the multiple rollers 1422 roll around the rolling axis 1423 and remain tangent to the bottom surface of the slide groove 111, thereby significantly reducing the friction between the adjusting element 141 and the slide groove 111.

[0044] Specifically, roller 1422 can be configured as a cylindrical roller bearing. In other embodiments, roller 1422 can also be configured as a spherical roller bearing.

[0045] In one embodiment, see Figure 6 and Figure 7The rolling frame 1421 has clearance grooves 1424 formed at both ends. The rolling element 142 also includes two locking parts 144. The locking parts 144 are fixedly connected to the adjusting element 141. The two locking parts 144 have locking tongues 1441 extending toward the rolling frame 1421. The two locking tongues 1441 press against the bottom surface of the clearance grooves 1424 to press the rolling frame 1421 against the bottom surface of the adjusting element 141. In this way, the deformation of the rolling frame 1421 during installation can be greatly reduced, thereby improving the installation reliability of the rolling element 142.

[0046] Optionally, see Figure 6 and Figure 7 The bottom surface of the adjusting member 141 has a receiving groove 1415, and the rolling frame 1421 is disposed in the receiving groove 1415. The roller 1422 extends out of the opening of the receiving groove 1415 and is tangent to the bottom surface of the slide groove 111. In this way, the size of the part of the rolling member 142 extending along the bottom surface of the adjusting member 141 can be reduced, so that the adjusting member 141 and the rolling member 142 can be installed in the shallow slide groove 111, thereby improving its applicability.

[0047] In one embodiment, the number of receiving slots 1415 may be multiple. The number of rolling elements 142 may be multiple. One rolling element 142 is disposed in each receiving slot 1415.

[0048] In this embodiment, see Figure 6 and Figure 7 There are two friction-reducing components 143. The two friction-reducing components 143 are respectively located on both sides of the adjusting component 141. In this way, it is easy for the friction-reducing components 143 to contact the groove side of the slide groove 111, and the amount of material used for the friction-reducing components 143 is reduced.

[0049] In one embodiment, the friction-reducing component 143 includes a first strip wall 1431, a second strip wall 1432, two end walls 1433, and a plurality of locking pins 1434. The first strip wall 1431 is disposed on the side of the adjusting component 141 and contacts the groove side of the slide groove 111. The second strip wall 1432 is bent and connected to the first strip wall 1431 and contacts the stop portion 112. The two end walls 1433 are respectively connected to the two ends of the first strip wall 1431 and the second strip wall 1432. The two end walls 1433 are respectively fixedly connected to the friction-reducing component 143 by the locking pins 1434.

[0050] In one embodiment, see Figure 6 and Figure 7The adjusting member 141 has four receiving grooves 1414 at its bottom corners. The friction-reducing member 143 also includes two mating walls 1435. The two mating walls 1435 are respectively connected to the two end walls 1433. The two friction-reducing members 143 have four mating walls 1435. The four mating walls 1435 are respectively embedded in the receiving grooves 1414. The four mating walls 1435 are respectively in contact with the bottom surface of the slide groove 111. In this way, the bottom of the adjusting member 141 integrates a fourth mating wall 1435 with friction-reducing and lubricating function and a rolling member 142 with friction-reducing force, thereby greatly improving the smoothness of the operation of the adjusting member 141 in the slide groove 111.

[0051] In this embodiment, see Figure 8 and Figure 9 The seat 100 with height adjustment function also includes a locking member 145, which has a first locking position and a first releasing position. When the locking member 145 is in the first locking position, the locking member 145 locks the adjusting member 141 to the seat frame 110. When the locking member 145 is in the first releasing position, the locking member 145 allows the adjusting member 141 to move relative to the seat frame 110.

[0052] In one embodiment, see Figure 9 The seat frame 110 has a through hole 118, and the adjusting member 141 has a plurality of limiting holes 1416 spaced apart along a first direction X1. The locking member 145 includes a fixing part 1451 and a plugging part 1452. The fixing part 1451 is connected to the seat frame 110, and the plugging part 1452 is movably connected to the fixing part 1451. The plugging part 1452 is configured to pass through the through hole 118 and selectively insert into one of the plurality of limiting holes 1416 to adjust the position of the adjusting member 141 relative to the seat frame 110. Thus, when the occupant needs to adjust the position between the seat body 120 and the seat frame 110, the plugging part 1452 is disengaged from the limiting hole 1416 and confined within the through hole 118, ensuring that the plugging part 1452 will not disengage from the seat frame 110. At this time, the plugging part 1452 no longer limits the adjusting member 141. Subsequently, the adjusting member 141 is moved along the length of the slide groove 111 so that another limiting hole 1416 corresponds to the through hole 118, and then the insertion part 1452 is inserted into the limiting hole 1416, so that the seat frame 110 and the seat body 120 are fixed together, and the position adjustment of the seat body 120 is completed.

[0053] Optionally, the locking member 145 and the first sliding member are located on both sides of the depth direction of the slide groove 111, and the through hole 118 connects to the bottom surface of the slide groove 111. In this way, the space between the two chair legs 114 of the seat frame 110 can be fully utilized to install the locking member 145.

[0054] In one embodiment, see Figure 9The fixing part 1451 is provided with a groove 14511, the opening of which is connected to a through hole 118. The locking member 145 also includes an elastic part 1453. The elastic part 1453 is disposed in the groove 14511. One end of the insertion part 1452 passes through the groove 14511, and the other end is connected to the elastic part 1453. When the locking member 145 is in the first released position, the insertion part 1452 abuts against the adjusting member 141. When the locking member 145 switches to the first locking position, the insertion part 1452 is inserted into one of the limiting holes 1416 under the action of the elastic part 1453. When the insertion part 1452 disengages from the limiting hole 1416, the elastic force of the elastic part 1453 can keep the insertion part 1452 abutting against the adjusting member 141. After the adjusting member 141 moves to the next position along the slide groove 111, the elastic part 1453 can automatically push the insertion part 1452 to insert into the next limiting hole 1416, thereby realizing automatic position adjustment.

[0055] The limiting hole 1416 can be constructed as a blind hole to ensure the overall structural strength of the adjusting member 141.

[0056] In one embodiment, see Figure 9 The locking member 145 also includes an operating part 1454 and an anti-wear sleeve 1455. The anti-wear sleeve 1455 connects to one end of the fixing part 1451 opposite to the insertion part 1452. One end of the operating part 1454 passes through the anti-wear sleeve 1455 and connects to the insertion part 1452. Thus, by operating the operating part 1454, the occupant can drive the insertion part 1452 out of the limiting hole 1416, thereby switching the locking member 145 to the first release position. After the position adjustment between the seat body 120 and the seat frame 110 is completed, the occupant releases the operating part 1454, and the insertion part 1452 can pass through the through hole 118 and insert into another limiting hole 1416 under the action of the elastic part 1453, so that the locking member 145 switches to the first locking position, realizing the fixation between the seat body 120 and the seat frame 110.

[0057] The operating part 1454 can be constructed as a steel cable, and the end of the insertion part 1452 opposite to the seat frame 110 can be provided with two staggered figure-eight holes to ensure that the operating part 1454 can extend into the insertion part 1452 and be fixed to the insertion part 1452.

[0058] In one embodiment, see reference. Figure 1 The seat 100 with height adjustment function also includes an adjustment handle 166. The adjustment handle 166 is located on the side of the seat plate 121. The adjustment handle 166 is connected to the operation unit 1454, and the occupant can control the adjustment member 141 to switch between a first unlocked position and a first locked position by controlling the adjustment handle 166.

[0059] In one embodiment, see Figure 10There are two adjusting members 141, each movably mounted on a corresponding seat leg 114. A locking member 145 extends along the second direction X2, with its two ends used to lock or release the corresponding adjusting member 141 from the corresponding seat leg 114. Thus, the occupant can simultaneously adjust both adjusting members 141 by operating the same locking member 145, improving operational convenience.

[0060] In this embodiment, please refer again. Figure 3 The adjusting member 141 is connected to the seat body 120 via a first fixing member 146 and a second fixing member 147. Specifically, the movable part 1411 of the adjusting member 141, away from the seat frame 110, is sequentially connected to the second connecting plate 132 of the adjuster 130 and the seat body 120 via the first fixing member 146. The first extension 1412 of the adjusting member 141, near the seat frame 110, is connected to the seat body 120 via the second fixing member 147. In this way, the first fixing member 146 and the second fixing member 147 reliably fix both ends of the adjusting member 141, ensuring the reliability of the connection between the adjusting member 141 and the seat body 120, and further fixing the installation of the adjuster 130.

[0061] In this embodiment, see Figure 10 The seat 100 with height adjustment function includes a drive member 150. One end of the drive member 150 is connected to the seat body 120, and the other end of the drive member 150 is driven to the seat frame 110. When it is necessary to adjust the position of the seat body 120 relative to the seat frame 110, the drive member 150 outputs driving force to move the seat body 120 relative to the seat frame 110.

[0062] In one embodiment, see Figure 10 The seat frame 110 also includes a first cross brace 115. The first cross brace 115 connects the two chair legs 114. The first cross brace 115 has a first connecting portion 116. One end of the drive member 150 is rotatably connected to the first connecting portion 116. The seat body 120 also includes a second connecting portion 1221. The other end of the drive member 150 is rotatably connected to the second connecting portion 1221. In this way, the driving force of the drive member 150 can be guaranteed to push the seat body 120 to move along the first direction X1.

[0063] In one embodiment, see Figure 10The chair leg 114 includes a first leg 1141 and a second leg 1142. The first leg 1141 extends along a first direction X1. The second leg 1142 extends along a second direction X2. The first leg 1141 connects to the second leg 1142. A first cross brace 115 connects the two first legs 1141. The seat frame 110 also includes a second cross brace 117. The second cross brace 117 connects the two second legs 1142. The second cross brace 117 can improve the overall stability of the seat frame 110.

[0064] In one embodiment, see Figure 10 The drive component 150 includes a gas spring 151. The gas spring 151 requires no external power; when the locking component 145 is released, it can move the seat body 120 relative to the seat frame 110, thus providing energy saving and environmental protection. Simultaneously, the gas spring 151 can also adapt to loads, providing reliable cushioning performance.

[0065] 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.
