Description

TECHNICAL FIELD

[0001] The present application relates to the field of aircraft parts, in particular to an aircraft seat which is easy to disassemble and install. BACKGROUND

[0002] The aircraft seat is the basic seat facility for passengers during flight, which is usually installed in the cockpit and passenger cabin, and is generally installed in the form of 3-4-3 or 3-3. During installation, the seat is usually fixedly connected with the seat slide rail through the leg lock connector of the chair leg, and the seat slide rail is installed in the aircraft floor to ensure that the installed aircraft is in a stable state.

[0003] However, most of the current seats are fixed seats installed on the floor through bolts, and during installation, the seat needs to be aligned with the fixed seat, the bolt needs to be aligned with the threaded hole and tightened, and the operation process is relatively complex. In the prior art, there are also some seats for quick disassembly and installation to solve the problem of complex installation process. For example, the applicant Hubei Aviation Jiatai Aircraft Equipment Co., Ltd. applied for a Chinese invention patent application CN108674667A entitled "aircraft seat and quick disassembly type chair leg lock" on April 28, 2018, which discloses a quick disassembly type chair leg lock of an aircraft seat. The lock includes a lock body, a pressing block and an elastic supporting device, the lock body is installed on the floor slide rail, the pressing block is connected with the lock body through a main lock body rotating pin shaft, and is locked or unlocked through a quick lock fastening screw and a quick lock hasp pin. The elastic supporting device can lift the pressing block after unlocking, facilitating quick disassembly. The locking or unlocking operation can be completed by rotating the quick lock fastening screw (only 1 / 4 turn). However, during installation, the operator needs to align the arc-shaped block of the main body with the arc-shaped groove of the seat slide rail, and there is still a complex operation of multiple alignments, which does not further solve the problem of complex installation process.

[0004] In addition, the patentee Zhejiang Jiahang Technology Co., Ltd. submitted a Chinese utility model patent CN219029741U entitled "aircraft seat chair leg connecting mechanism", which discloses an aircraft seat chair leg connecting mechanism. The mechanism mainly includes a guide rail, a spring, an expansion top block, an extension rod and a locking clamping assembly. By inserting the chair leg into the guide rail, the spring and the expansion top block are used to realize automatic locking, and at the same time, by pressing the rod and the ring, the locking state can be quickly released, simplifying the disassembly process and improving the operation efficiency. However, as the spring used to elastically fix the expansion block is used for a long time, its elastic return decreases, so that it cannot provide enough top force for the expansion top block, resulting in that the expansion rod and the fixed rod cannot be kept in close contact, causing the seat to loosen.

[0005] In summary, the conventional aircraft seat installation method requires multiple installation and alignment of components during the installation process, which is relatively complicated. In addition, after the seat becomes loose, there is no way to compensate for the decrease in spring elasticity except for the initial replacement of new parts, thereby causing the seat to become loose and lose stability. Summary of the Invention

[0006] The present invention is completed in view of the above problems, and its purpose is to provide an aircraft seat that is easy to install and disassemble and has high stability.

[0007] According to a first aspect of the present invention, there is provided an aircraft seat, and more particularly, an aircraft seat capable of rapid assembly or disassembly. The aircraft seat comprises a seat body and a mounting seat assembly, wherein the mounting seat assembly comprises:

[0008] A seat slide rail, wherein the seat slide rail is provided with a slide groove in the sliding direction;

[0009] A mounting buckle seat is connected to the lower end of the chair leg of the seat body, the mounting buckle seat is provided with a support block extending perpendicular to the sliding direction in the sliding direction, and the upper surface of the mounting buckle seat is provided with a connecting seat and a fixing seat;

[0010] a locking assembly comprising a locking block and a rod assembly, wherein the lower end of the rod assembly is connected to the locking block; and

[0011] The fixing assembly comprises a fixing bolt and a limiting portion, wherein the lower end of the fixing bolt is connected to the limiting portion.

[0012] The locking block is installed in a form-fitting manner within the slide groove, the support block abuts the upper surface of the seat slide rail, the rod assembly passes through the connecting seat and is rotatable within the connecting seat, and the fixing bolt is screwed through the fixing seat and abuts the slide groove via the stop portion. Preferably, the locking assembly also includes a stop rod installed at the top of the rod assembly for operating the rotation of the locking block during installation and removal.

[0013] It should be noted that the term "longitudinal" in the present invention refers to the sliding direction along the slide groove, and the term "transverse" refers to the direction perpendicular to or approximately perpendicular to the sliding direction along the slide groove. Figure 3 As shown, D1 is the "longitudinal" direction, which is parallel or substantially parallel to the sliding direction of the slideway, D2 is the vertical direction, and D3 is the "transverse" direction, which is perpendicular to both D1 and D2.

[0014] The present application sets the locking assembly and the fixing assembly, when installing the seat, the installation buckle seat installed with the seat body, by inserting the locking block into the target position inside the sliding groove, by manually rotating the limiting rod, the position of the locking block is changed from longitudinal to transverse. At this time, by rotating the fixing bolt, the limiting part abuts against the bottom of the sliding groove. With further tightening of the fixing bolt, the locking block is lifted in the vertical direction, further abutting against the upper edge of the sliding groove, so that the friction between the locking block and the sliding groove is increased, thereby realizing the stable installation of the aircraft seat. This installation process eliminates the multiple alignment operations between the parts, such as bolts and threaded holes, in the prior art, and easily realizes the quick installation or disassembly of the aircraft seat.

[0015] Preferably, in another embodiment of the present application, the locking assembly further comprises at least two elastic limiting mechanisms, which comprise:

[0016] a sliding hole, the upper end of which abuts against the upper edge of the sliding groove;

[0017] a first spring arranged in the sliding hole; and

[0018] two limiting balls arranged at the two ends of the first spring,

[0019] wherein the first spring makes the two limiting balls abut against the sliding groove, and the two elastic limiting mechanisms are arranged in the locking block and are arranged on the two sides of the locking block, respectively. Preferably, the two elastic limiting mechanisms are symmetrically arranged in the locking block. Preferably, the locking assembly has at least four elastic limiting mechanisms arranged in the locking block, and two elastic limiting mechanisms are arranged on each side of the locking block, respectively. More preferably, the four elastic limiting mechanisms are symmetrically arranged in the locking block.

[0020] In another embodiment of the present application, a guide groove extending in the sliding direction is arranged at the abutting position of the sliding groove and the two limiting balls, and the limiting balls abut against the guide groove.

[0021] By arranging the elastic limiting mechanism, during the installation process, when the position of the locking block is changed from longitudinal to transverse by manually rotating the limiting rod, the locking block is in a relatively fixed state with the guide groove, i.e. the seat slide rail, through the elastic limiting mechanism, so that the locking block and the seat slide rail are further fixed. In addition, due to the arrangement of the elastic limiting mechanism, the friction between the locking block and the sliding groove is reduced through the action of the spring and the limiting ball, which is more conducive to installation.

[0022] Preferably, in another embodiment of the present application, the bottom of the sliding groove is provided with a long rack in the sliding direction, and the lower end of the limiting part is connected to a limiting rack which is engaged with the long rack. Through the engagement of the limiting rack and the long rack, the relative position between the mounting buckle and the seat slide rail in the sliding direction is further limited, and the position of the seat body in the sliding direction is further fixed.

[0023] Preferably, the lower surface of the mounting buckle is provided with a sliding part, for example, the sliding part can be implemented as a gear, preferably a rolling gear, which is engaged with the long rack and can drive the mounting buckle to slide in the sliding groove in the sliding direction, thereby facilitating the movement of the mounting buckle, i.e. the seat body, during installation. By providing a sliding part on the lower surface of the mounting buckle, the movement of the mounting buckle in the sliding direction during installation is smoother, and the time required to move the mounting buckle to the target position is reduced.

[0024] Preferably, in another embodiment of the present application, the rod assembly includes a rotating rod and a movable rod, the movable rod is sleeved in the rotating rod, the movable rod and the rotating rod cannot rotate relative to each other, and a second spring is arranged between the movable rod and the rotating rod, both ends of the second spring are fixedly connected with the movable rod and the rotating rod.

[0025] In another embodiment of the present application, the locking assembly further includes a threaded sleeve screwed into the connecting seat, and the rod assembly is rotationally connected in the threaded sleeve.

[0026] When the wear between the locking block and the sliding groove causes the size in the vertical direction to be inconsistent, or the elastic force of the second spring decreases with the use time, at this time, by screwing the threaded sleeve, the position of the threaded sleeve in the vertical direction is changed, thereby changing the relative distance between the locking block and the mounting buckle, so that the upper surface of the locking block in the transverse state always maintains the abutting state with the upper edge of the sliding groove, and unnecessary replacement of the spring when the elastic force decreases is also avoided, ensuring the stability of the seat body after installation.

[0027] In another embodiment of the present application, the top of the fixing seat is further provided with an anti-loosening assembly for preventing the fixing bolt from loosening. For example, it can be achieved by an anti-loosening washer, and in the present application, it is achieved by a limiting disc, the position of which can be elastically fixed by a limiting hemisphere. When the fixing bolt is not subjected to external force, it will not loosen, thereby enhancing the stability of the structure.

[0028] In addition, in another embodiment of the present application, an aircraft seat provided with a folding footboard is also provided, the height of the folding footboard in the vertical direction can be adjusted according to the actual needs of the user to provide foot support, further improving the riding comfort, and when not needed, it can be folded up, which is beneficial to improve the leg space of the user.

[0029] Thus, the present application provides an aircraft seat which is easy to install or disassemble, and also has multiple limiting and fixing devices, thereby reducing the multiple alignment of parts during installation and simplifying the installation process. BRIEF DESCRIPTION OF DRAWINGS

As shown in the figure, Figure 10 and Figure 11 As shown in the figure, each group of elastic limiting mechanisms 58 comprises a first spring 581, two placing rings 582 and two limiting balls 583, the first spring 581 is movably connected inside the sliding hole 573, the two placing rings 582 are respectively abutted on the upper and lower ends of the first spring 581, and the two limiting balls 583 are movably connected inside the placing ring 582. The diameter of the limiting ball 583 is consistent with the size of the sliding hole 573, the side edge of the limiting ball 583 away from the placing ring 582 is abutted on the inside of the limiting hole 574, and the upper and lower sides of the sliding groove 31 are provided with guide grooves 312, and the side of the limiting ball 583 away from the placing ring 582 is abutted on the inside of the guide groove 312.

[0055] The upper surface of the fixed seat 24 is provided with a threaded hole 241 in the center, the fixed assembly 6 comprises a fixed bolt 61 and a limiting tooth seat 65, and the fixed bolt 61 is screwedly connected inside the threaded hole 241. Preferably, the top of the fixed seat 24 is also provided with an anti-loosening assembly. Specifically, as shown in the figure, Figure 12 、 Figure 13 and Figure 14 As shown in the figure, the anti-loosening assembly comprises a limiting disc 613, four groups of through holes 6131, four groups of mounting holes 243, a limiting hemisphere 245 and a third spring 244. The outer side of the fixed bolt 61 and above the fixed seat 24 is fixedly connected with the limiting disc 613, the upper surface of the limiting disc 613 is equidistantly provided with the four groups of through holes 6131, the upper surface of the fixed seat 24 is equidistantly provided with the four groups of mounting holes 243, the inside of the mounting hole 243 is fixedly connected with the third spring 244, the upper end of the third spring 244 is fixedly connected with the limiting hemisphere 245, the limiting hemisphere 245 is elastically abutted inside the through hole 6131, the lower end of the fixed bolt 61 is rotatably connected with a mounting column 62, the lower end of the mounting column 62 is fixedly connected with a T-shaped block 64 through a connecting bolt 63, and the limiting tooth seat 65 is fixedly connected with the lower surface of the T-shaped block 64 and is fixed between the limiting tooth seat 65 and the long toothed bar 311.

[0056] The present application aims to simplify the installation process of the aircraft seat. During installation, only need to insert the sliding member 4 into the seat slide rail 3 at any position, and then push the seat body 1 to the desired position according to the installation interval. Once the position of the seat body 1 is determined, the limiting rod 55 is manually rotated to change by 90 degrees. In this process, the limiting rod 55 drives the rotating rod 52 to rotate through the movable rod 53, and the rotating rod 52 drives the locking block 57 to rotate inside the sliding groove 31. After rotating by 90 degrees, the locking block 57 changes from longitudinal to transverse, thereby being firmly fixed inside the sliding groove 31. At this time, the position of the seat body 1 is preliminarily fixed.

[0057] During the rotation of the locking block 57, the limiting ball 583 is pressed into the sliding hole 573, and at this time the first spring 581 is compressed. When the locking block 57 is rotated in place, the limiting ball 583 is just aligned with the guide groove 312, and at this time the limiting ball 583 loses the pressing force, and the first spring 581 recovers the deformation, thereby exerting an elastic pressing force on the limiting balls 583 at both ends, so that the limiting balls 583 abut against the inside of the guide groove 312. At this time, the position of the locking block 57 is fixed.

[0058] Secondly, during the rotation of the limiting rod 55, the limiting rod 55 needs to be pulled upwards to ensure that the limiting rod 55 can pass over the limiting seat 23. After the limiting rod 55 is rotated in place, the position of the limiting rod 55 is just parallel to the limiting groove 231 on the limiting seat 23. At this time, only need to press the limiting rod 55 downwards to fix it inside the limiting groove 231, thereby fixing the position of the locking block 57 for the second time. At this time, the seat body 1 is firmly fixed above the seat slide rail 3 through the connected installation buckle 2.

[0059] Finally, use a wrench to rotate the fixing bolt 61. During the rotation and descent of the fixing bolt 61, the limiting tooth seat 65 is indirectly engaged with the long rack 311. Once the limiting tooth seat 65 is engaged with the long rack 311, the seat body 1 cannot be moved forward and backward at this time.

[0060] During the rotation of the fixing bolt 61 using the wrench, the limiting disc 613 and the limiting hemisphere 245 play an important role. When the wrench rotates the fixing bolt 61, the limiting disc 613 has a through hole 6131 on its surface, which corresponds to the limiting hemisphere 245 in the mounting hole 243. When the limiting tooth seat 65 is engaged with the long rack 311 during the rotation of the fixing bolt 61, the through hole 6131 on the limiting disc 613 is just aligned with the limiting hemisphere 245. At this time, the elastic force of the third spring 244 causes the limiting hemisphere 245 to be firmly pressed inside the through hole 6131, thereby avoiding the loosening of the fixing bolt 61 and effectively enhancing the stability of the seat body 1. Not only simplifies the installation process, but also ensures that the seat body 1 will not loosen due to vibration or other factors during flight.

[0061] When the lock block 57 and the sliding groove 31 are worn and inconsistent in size, the position of the threaded sleeve 51 is adjusted at this time, the relative height of the lock block 57 and the mounting buckle 2 is changed, so that the upper surface of the lock block 57 in the transverse state can always be in abutting state with the upper surface of the sliding groove 31, ensuring the stability of the seat body 1 after installation.

[0062] The four groups of vertical blocks 532 are respectively slidingly connected inside the vertical grooves 522 on the corresponding side. The advantage of this is that the movable rod 53 can slide up and down inside the jack 521, but will not rotate relative to the jack 521, so that when the limiting rod 55 is rotated, the limiting rod 55 can drive the rotating rod 52 to rotate through the movable rod 53.

[0063] Specifically, the left and right sides of the mounting buckle 2 are fixedly connected with support blocks 21, and the lower surfaces of the support blocks 21 abut against the upper surface of the seat slide rail 3.

[0064] The support blocks 21 increase the contact area between the mounting buckle 2 and the seat slide rail 3, so that the contact between the mounting buckle 2 and the seat slide rail 3 is more uniform and stable. The increased contact area can disperse the pressure and load, reduce local stress concentration, thereby reducing structural stress, avoiding fatigue and damage caused by excessive stress, and prolonging the service life of the mounting buckle 2 and the seat slide rail 3.

[0065] Specifically, the sliding member 4 includes a mounting plate 41, two groups of side plates 42 and a rolling gear 43, the mounting plate 41 is fixedly connected inside the top wall of the mounting buckle 2 through bolts, the two groups of side plates 42 are respectively fixedly connected on the left and right sides of the mounting plate 41, and the rolling gear 43 is rotatably connected between the two groups of side plates 42. The rolling gear 43 is engaged on the long rack 311.

[0066] When installing the seat body 1, the rolling gear 43 is only placed inside the sliding groove 31 and engaged with the long rack 311, so that the process of installing the seat body 1 is simpler and more intuitive. When the seat body 1 is pushed to move, the rolling gear 43 is indirectly driven to move on the long rack 311. Since the rolling gear 43 is designed, it can smoothly roll on the long rack 311, so that the movement of the seat body 1 is more stable and easy.

[0067] The outer side of the threaded sleeve 51 is fixedly connected with a hexagonal seat 511.

[0068] When adjusting the position of the threaded sleeve 51, the hexagonal seat 511 can be rotated by a wrench, so as to achieve the purpose of adjusting the position of the threaded sleeve 51.

[0069] The lower end of the movable rod 53 is fixedly connected with a second spring 54, which is located inside the insertion hole 521, and the lower end of the second spring 54 is fixedly connected to the inner bottom wall of the insertion hole 521.

[0070] When the limiting rod 55 is embedded in the limiting groove 231, the elastic tension of the second spring 54 can firmly and elastically fix the limiting rod 55 inside the limiting groove 231 through the movable rod 53, which can ensure that the limiting rod 55 will not move due to external interference or vibration, and maintain the required position or state, thereby ensuring that the position of the locking block 57 will not rotate automatically.

[0071] Specifically, the two sides of the rotating rod 52 are fixedly connected with insertion blocks 524, the upper surface of the mounting buckle 2 is provided with a first movable hole 571, the two sides of the first movable hole 571 are provided with insertion grooves 5711, the insertion blocks 524 are slidingly connected inside the corresponding insertion grooves 5711, the lower end of the rotating rod 52 is inserted into the first movable hole 571, the lower end of one side of the rotating rod 52 is provided with a first connecting hole 523, one side of the locking block 57 is provided with a first side hole 572, the first side hole 572 is in communication with the first connecting hole 523, and the locking bolt 56 is threaded through the first side hole 572 and the first connecting hole 523.

[0072] The rotating rod 52 and the locking block 57 are connected and fixed through the locking bolt 56, which is convenient for subsequent maintenance and replacement of parts. Secondly, when the rotating rod 52 is inserted into the first movable hole 571, the insertion blocks 524 can be aligned with the insertion grooves 5711, which can realize quick and accurate positioning between the rotating rod 52 and the locking block 57, and make the insertion of the locking bolt 56 more convenient.

[0073] As shown in Figure 12 , the lower end of the fixed bolt 61 is fixedly connected with a bottom column 611, and the outer side of the bottom column 611 is rotatably connected to the inside of the mounting column 62 through a bearing 612.

[0074] As shown in Figure 13 and Figure 14 , the bottom column 611 and the mounting column 62 form a rotating structure through the bearing 612, and the mounting column 62 is fixedly connected with the T-shaped block 64, which can ensure that the mounting column 62 will not rotate when the fixed bolt 61 rotates in the threaded hole 241, but will only move along the vertical direction, thereby indirectly achieving the purpose of adjusting the height of the T-shaped block 64.

[0075] The outer lower end of the mounting column 62 is provided with a second connecting hole 621, the upper surface of the T-shaped block 64 is provided with a second movable hole 641, the front and rear sides of the T-shaped block 64 are provided with a second side hole 642, the second side hole 642 penetrates the second movable hole 641, the lower end of the mounting column 62 is inserted into the inside of the second movable hole 641, and the connecting bolt 63 is screwed through the inside of the second side hole 642 and the second movable hole 641.

[0076] The mounting column 62 and the T-shaped block 64 are connected and fixed through the connecting bolt 63, which is convenient for subsequent maintenance and replacement of parts.

[0077] As shown in Figure 6 , the inside of the mounting buckle 2 is provided with two groups of side grooves 242 on both sides, and the left and right sides of the T-shaped block 64 are fixedly connected with two groups of side blocks 643, and the side blocks 643 are slidingly connected in the inside of the corresponding side groove 242.
