Description

Technical Field

[0001] This utility model belongs to the field of aviation seat technology, specifically relating to an aviation seat frame with adjustable armrest angle. Background Technology

[0002] Armrests are an important part of aircraft seats. They not only provide passengers with extra support and comfort during flight, but may also integrate a variety of functions. Armrests may include passenger control functions, such as flight attendant call bells and indicator lights, which improve passenger convenience. Some designs use simple track wheels to replace traditional handheld phones to control in-flight entertainment systems and games. Some designs also provide built-in telephone consoles, allowing passengers to communicate or make calls during flight.

[0003] In the prior art, such as the aircraft seat armrest angle adjustment device with application number 202220063943.9, there are: armrest bracket, support arm assembly and panel assembly. The support arm assembly includes a support arm and a first drive part. One end of the support arm is hinged to the armrest bracket. The first drive part has a fixed end and a movable end. The fixed end of the first drive part is hinged to the armrest bracket and the movable end is hinged to the support arm. It is used to drive the support arm to rotate around the rotation axis of its hinge point with the armrest bracket. The panel assembly includes a panel and a second drive part.

[0004] In the above, the combination of the support arm, the first drive unit and the handrail bracket significantly expands the rotation range of the handrail and basically realizes the multi-angle flipping function of the handrail bracket. However, after reading the technical solution, it is found that the structure uses too many hinged transmission rods. Multiple transmissions will cause a decrease in rotation efficiency, which in turn requires a lot of force when the handrail is flipped, which is not conducive to the convenient flipping of the handrail, and also cannot meet the comfort needs of passengers. Utility Model Content

[0005] The purpose of this invention is to provide an aircraft seat frame with adjustable armrest angle, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seat mechanism including an armrest, the armrest having an adjustment mechanism, the adjustment mechanism including a connecting bead embedded in the bottom of the armrest, a spring sleeved on the lower surface of the connecting bead, a sliding rod fixedly installed at the bottom of the spring, a U-shaped frame slidably fitted on the surface of the sliding rod, a mounting post adapted to be installed at the center of the inner side of the U-shaped frame, a universal ball on the top of the mounting post, an inner retaining ring rotatably fitted on the outer surface of the universal ball, the surface of the inner retaining ring fitting with the armrest, and the inner retaining ring being an integrally formed silicone ring.

[0007] As a preferred embodiment of this utility model, the spiral frame is composed of separable multi-segment frames, and the spiral frame is equipped with a stepless adjustment component. The stepless adjustment component includes a side rod adapted to be installed on the outer side of the spiral frame, and a crank rod is fitted on the surface of the side rod.

[0008] In a preferred embodiment of this utility model, the cranks are arranged in a symmetrical shape, and a positioning rod is rotatably fitted at the bottom of the cranks, with a starter placed at the bottom of the positioning rod.

[0009] As a preferred embodiment of this utility model, the lower surface of the herringbone frame is provided with a connecting seat, the number of which is several, and a pin is adapted to be installed between two of the connecting seats.

[0010] In a preferred embodiment of this utility model, the pin is fitted with a stroke mechanism, which includes a lifting assembly that rotates with the outer surface of the pin. A lead screw drive is fitted at the bottom of the lifting assembly and is electrically connected to the starter.

[0011] In a preferred embodiment of this utility model, the lead screw drive component is fitted with a support chair frame via a built-in box at the bottom. The support chair frame is made of multi-end structure splicing, and the position of the lead screw drive component is aligned with the armrest.

[0012] In a preferred embodiment of this invention, the rotation angle range of the two cranks is acute, and the center of the positioning rod always coincides with the bottom center of the crank.

[0013] In a preferred embodiment of this utility model, the number of connecting beads is several, and the several connecting beads are arranged at the corner of the handrail.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the coordinated design of the seat mechanism and the adjustment mechanism allows the armrest to be infinitely adjustable, saving rotation time. Furthermore, the connection between the connecting ball and the spring allows the armrest to slide smoothly along the inner groove of the U-shaped frame, preventing the armrest from bumping into the passenger's hand. This greatly improves the adjustment range of the armrest and meets diverse usage needs. Simultaneously, the sliding cooperation between the slide rod and the U-shaped frame provides good support at the bottom of the armrest when it is flipped, improving the chance of the armrest falling off. The cooperation between the universal ball and the mounting post, through the spherical support of the universal ball, allows the multi-segmented U-shaped frame to stabilize the armrest at any angle when it is flipped, demonstrating the infinitely adjustable function of the armrest. The connection between the inner retaining ring and the universal ball makes the surface of the universal ball slightly rough, reducing the chance of the armrest slipping during rotation.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] This utility model embodiment proposes an aircraft seat frame with adjustable armrest angle, including a seat mechanism 100; for example, such as Figures 1-3 As shown.

[0024] The seat mechanism 100 includes an armrest 102, and the armrest 102 is equipped with an adjustment mechanism 200. The adjustment mechanism 200 includes a connecting bead 201 embedded in the bottom of the armrest 102. A spring 202 is sleeved on the lower surface of the connecting bead 201. A slide rod 203 is fixedly installed at the bottom of the spring 202. A U-shaped frame 204 is slidably fitted on the surface of the slide rod 203. A mounting post 207 is adapted to be installed at the center of the inner side of the U-shaped frame 204. A universal ball 206 is provided on the top of the mounting post 207. An inner retaining ring 205 is rotatably sleeved on the outer surface of the universal ball 206. The surface of the inner retaining ring 205 is fitted with the armrest 102, and the inner retaining ring 205 is an integrally molded silicone ring.

[0025] The loop frame 204 is composed of separable multi-segment frames, and the loop frame 204 is equipped with a stepless adjustment component 208. The stepless adjustment component 208 includes a side rod 208a adapted to be installed on the outer side of the loop frame 204, and a crank rod 208b is fitted on the surface of the side rod 208a.

[0026] The crank levers 208b are arranged in a symmetrical V-shape. A positioning rod 208c is rotatably sleeved at the bottom of the crank levers 208b, and a starter 303 is placed at the bottom of the positioning rod 208c.

[0027] Specifically, through the coordinated arrangement of the seat mechanism 100 and the adjustment mechanism 200, the armrest 102 can be infinitely adjusted, saving rotation time. Furthermore, the connection between the connecting bead 201 and the spring 202 allows the armrest 102 to slide smoothly along the inner groove of the U-shaped frame 204, preventing the armrest 102 from bumping into the passenger's hand. This greatly improves the adjustment range of the armrest 102, meeting diverse usage needs. Simultaneously, the sliding cooperation between the slide rod 203 and the U-shaped frame 204 allows the armrest 102 to... When the handrail 102 is flipped, its bottom is well supported, which improves the situation where the handrail 102 will fall off. The cooperation between the universal ball 206 and the mounting column 207, through the spherical support of the universal ball 206, allows the multi-segmented loop frame 204 to stabilize the handrail 102 at any angle when it is flipped, which reflects the stepless adjustment function of the handrail 102. The engagement between the inner retaining ring 205 and the universal ball 206 makes the surface of the universal ball 206 slightly rough, which reduces the possibility of the handrail 102 slipping during rotation.

[0028] Through the rotational cooperation of the crank lever 208b, the side lever 208a, and the positioning lever 208c, the loop frame 204 is mechanically locked when it is displaced. At this time, the handrail 102 can rotate infinitely around the surface of the universal ball 206 in one position, which makes the handrail 102 more practical and meets the different usage needs of passengers.

[0029] The lower surface of the loop frame 204 is provided with a connecting seat 209; for example, such as Figures 2-4 As shown.

[0030] The number of the connecting seats 209 is several, and a pin 210 is adapted to be installed between two of the connecting seats 209.

[0031] The pin 210 is fitted with a stroke mechanism 300, which includes a lifting assembly 301 that rotates with the outer surface of the pin 210. The bottom of the lifting assembly 301 is fitted with a lead screw drive 302, which is electrically connected to the starter 303.

[0032] The lead screw drive component 302 is fitted with a support chair frame 101 through a built-in box at the bottom. The support chair frame 101 is made of multi-end structure splicing, and the position of the lead screw drive component 302 is aligned with the armrest 102.

[0033] Specifically, through the matching installation of the connecting seat 209 and the pin 210, the handrail 102 is stably supported on one side when it is flipped. The cooperation between the lifting kit 301 and the screw drive 302 allows the handrail 102 to move horizontally and be lifted vertically, making the handrail 102 more suitable for passengers, convenient and efficient. Through the electrical connection between the starter 303 and the screw drive 302, the screw drive 302 can be started and stopped at any time, allowing passengers to use the handrail 102 more conveniently and quickly.

[0034] The rotation angle range of the two crank levers 208b is acute; for example, such as Figures 3-5 As shown.

[0035] The center of the positioning rod 208c always coincides with the bottom center of the crank rod 208b.

[0036] The number of connecting beads 201 is several, and several connecting beads 201 are arranged at the corner of the handrail 102.

[0037] Specifically, the rotation range of the two cranks 208b is acute angle, which can reduce the wear of the cranks 208b during the mechanical locking process and further improve the adaptability of the loop frame 204 and the armrest 102. At the same time, several connecting beads 201 can provide a balanced and symmetrical support and stability for the armrest 102.

[0038] Working principle: First, starter 303 is turned on, which makes lead screw drive 302 move. Lead screw drive 302 drives lifting kit 301 to achieve the lifting effect of handrail 102, helping handrail 102 to fit with passenger's hand.

[0039] Then, when the passenger flips the handrail 102, the connecting bead 201 at the bottom causes the spring 202 to stretch. The elastic force generated by the spring 202 reacts to the slide bar 203, causing the slide bar 203 to slide stably along the inner groove of the loop frame 204, so that one side of the handrail 102 is raised, which meets the support needs of the passenger's elbow.

[0040] When passengers need to place their items briefly, the handrail 102 is quickly rotated. The inner retaining ring 205 and the universal ball 206 provide stepless adjustment. The handrail 102 can be adjusted to any position according to the passenger's actual needs. After the position is determined, the crank lever 208b and the side lever 208a are engaged, so that the U-shaped frame 204 and the handrail 102 stop rotating. The handrail 102 can be in the predetermined position to meet the diverse needs of passengers.
