[0034] As mentioned earlier, the industry is striving to achieve greater diversity and comfort in the design of in-vehicle seat armrests, while also considering the expansion and application of armrest screens.

[0035] In view of this, embodiments of this application provide a seat armrest, a seat, and a vehicle.

[0036] As shown in Figures 1, 2, 7, and 8, the seat armrest 100 provided in this embodiment includes an armrest body 10 and an armrest screen 20. The armrest body 10 includes an armrest arm 11 and an armrest panel 12, with the armrest panel 12 movably connected to the armrest arm 11. The armrest screen 20 is limitedly connected to the armrest body 10 and includes a visible screen 21 and a hidden screen 22. In this embodiment, the armrest panel 12 has a folded state and an unfolded state. In the folded state, the armrest panel 12 is positioned above the armrest arm 11 and abuts against the armrest arm 11, allowing interaction via the visible screen 21. In the unfolded state, the armrest panel 12 is positioned outside the armrest arm 11 and abuts against the armrest arm 11, allowing interaction via the hidden screen 22. Specifically, the armrest panel 12 can be connected to the armrest arm 11 via a concealed hinge.

[0037] As can be seen from the above, the seat armrest 100 of this application can expand its function by flipping the armrest panel 12 outward, thus increasing the headrest width of the seat armrest 100. During this process, the armrest screen 20 can ensure interaction between the armrest screen 20 and the user through automatic switching between the visible screen 21 and the hidden screen 22, so as to facilitate the user's operation of the armrest screen 20 and improve the user experience. It should be noted that the width of the armrest panel 12 of this application is the same as the width of the armrest arm 11, so when the armrest panel 12 is in the unfolded state, the headrest width of the seat armrest 100 can be doubled.

[0038] As shown in Figures 1, 2, 7, and 8, in one embodiment, the hidden screen 22 is configured as an inner and outer screen structure, and the hidden screen 22 can be folded or unfolded under the action of the armrest panel 12. Along the width direction of the armrest body 10, the size of the visible screen 21 on the armrest screen 20 is smaller than the size of the hidden screen 22. That is, when the armrest panel 12 is folded, the armrest screen 20 is also folded, and correspondingly, the visible screen 21 of the armrest screen 20 is specifically the screen of the armrest screen 20 in the folded state; when the armrest panel 12 is unfolded, the armrest screen 20 is also unfolded, and correspondingly, the hidden screen 22 of the armrest screen 20 is specifically the screen of the armrest screen 20 in the unfolded state. Here, the armrest screen 20 can specifically be a flexible screen similar to a foldable phone, and the interface on the armrest screen 20 used for interaction can automatically switch back and forth between the visible screen 21 and the hidden screen 22.

[0039] It should be noted that the armrest screen 20 is partially embedded in and connected to the armrest panel 12, allowing the user to unfold the armrest screen 20 while folding the armrest panel 12 outwards. This satisfies the user's need for the armrest panel 12 to fold or unfold the armrest screen 20. Here, the portion of the armrest screen 20 embedded in the armrest panel 12 can be connected to the armrest panel 12 using magnetic attraction or a tight fit, to allow for the subsequent removal of the armrest screen 20 from the armrest body 10.

[0040] In one embodiment, the hidden screen 22 is mounted on the armrest 11 and is detachably connected to the armrest body 10. That is, the armrest screen 20 can be completely detached from the armrest body 10 before interaction, which further facilitates the user's operation of the armrest screen 20.

[0041] It should be noted that the armrest screen 20 has a power interface on the portion located at the armrest arm 11, and correspondingly, the armrest arm 11 has a PIN pin (not shown) that matches the power interface (not shown). When the armrest screen 20 is assembled onto the armrest body 10, the PIN pin can be electrically connected to the armrest screen 20 through the power interface, allowing the armrest arm 11 to both charge the armrest screen 20 and transmit data from the armrest screen 20, thus creating conditions for the subsequent automatic unlocking of the armrest screen 20.

[0042] In one embodiment, one end of the hidden screen 22 is abutted against the armrest 11, and the hidden screen 22 can be magnetically secured to the armrest 11. This facilitates the installation and removal of the hidden screen 22 from the armrest 11. Here, the armrest 11 is equipped with a magnetic component, and the hidden screen 22 is equipped with a ferromagnetic component that can be attracted by the magnetic component. By using the magnetic component to attract the ferromagnetic component, the hidden screen 22 can be magnetically secured to the armrest 11.

[0043] It should be noted that since the armrest 100 is horizontal when used in the seat 200, the armrest screen 20 is also horizontal when it is mounted on the armrest body 10. The armrest screen 20 can also be placed flat on the armrest arm 11 under its own weight. Therefore, the magnetic attraction force of the armrest arm 11 when locking the armrest screen 20 can be set to be very small.

[0044] As shown in Figure 3, one of the hidden screen 22 and the armrest 11 has a slot 23, and the other has a protruding claw 111. When one end of the hidden screen 22 is engaged with the armrest 11, the claw 111 is inserted into the slot 23 and can swing relative to the slot 23; and when the hidden screen 22 is locked by the armrest 11, the claw 111 abuts against the groove wall 231 of the slot 23 for limitation. That is, the claw 111 has a rotational stroke within the slot 23. In other words, through the cooperation between the claw 111 and the slot 23, the engagement between the hidden screen 22 and the armrest 11 is specifically achieved, and the rotation angle of the hidden screen 22 when it is lifted off the armrest 11 can be limited. Here, the slot 23 is provided on the hidden screen 22, and the claw 111 is provided on the armrest 11. It is understood that in other embodiments, the slot 23 may also be disposed on the armrest 11, and the claws 111 may be disposed on the hidden screen 22. It should be noted that the number and arrangement of the claws 111 can be specifically set according to the usage requirements, and will not be elaborated here.

[0045] As shown in Figure 4, in one embodiment, a pop-out mechanism 112 is provided on the armrest 11. The pop-out mechanism 112 can push the armrest screen 20 to make the armrest screen 20, which is locked onto the armrest 11, lift up and release the locking of the armrest screen 20. That is, by using the pop-out mechanism 112 to push the armrest screen 20, the armrest screen 20 can be automatically lifted off the armrest 11. At the same time, the power interface on the armrest screen 20 can be detached from the pin on the armrest 11, which makes it easier for the user to pick it up and further facilitates the user to remove the armrest screen 20 from the armrest 11.

[0046] It should be noted that when the pop-up mechanism 112 pushes the armrest screen 20 up from the armrest arm 11, the force exerted by the pop-up mechanism 112 on the armrest screen 20 when pushing it up needs to be greater than the sum of the magnetic attraction force that locks the armrest screen 20 to the armrest arm 11 and the force exerted when the armrest screen 20 is connected to the armrest panel 12.

[0047] As shown in Figure 4, in one embodiment, the pop-out mechanism 112 includes a push-up protrusion 1121, an elastic element 1122, and a push rod 1123. The push-up protrusion 1121 is slidably connected to the armrest 11 and can abut against the armrest screen 20. The elastic element 1122 is pre-compressed and housed within the push-up protrusion 1121, with one end abutting against the inner wall of the push-up protrusion 1121 and the other end abutting against the armrest 11. One end of the push rod 1123 abuts against the inner wall of the push-up protrusion 1121. Thus, the pop-out mechanism 112 can utilize the elastic element 1122 to push the push-up protrusion 1121, thereby pushing the armrest screen 20, while the push rod 1123 can forcefully push the push-up protrusion 1121 to unlock the armrest screen 20 from the armrest 11. Here, the number of elastic elements 1122 can be one, two, or even more. Specifically, the elastic elements 1122 can be configured as compression springs, rubber sleeves, or other highly elastic accessories.

[0048] As shown in Figure 5, in one embodiment, the armrest 11 is also provided with an unlocking mechanism 113. The unlocking mechanism 113 is electrically connected to the armrest screen 20, and can be activated under the control of the armrest screen 20 to release the lock on the armrest screen 20. That is, the armrest screen 20 can control the unlocking mechanism 113 to be activated, and use the unlocking mechanism 113 to control the unlocking of the armrest screen 20, so that the armrest screen 20 can automatically control the unlocking, which further facilitates the user to remove the armrest screen 20 from the armrest body 10. Here, the armrest screen 20 is provided with a virtual unlock button (not shown). The user can trigger the armrest screen 20 by clicking the virtual unlock button on the hidden screen 22, so that the armrest screen 20 can transmit a signal to the unlocking mechanism 113 through the power interface and control the unlocking mechanism 113 to be activated.

[0049] In one embodiment, the unlocking mechanism 113 can provide power to the push rod 1123 on the pop-out mechanism 112, thereby forcibly pushing the push protrusion 1121 by the push rod 1123 to unlock the armrest screen 20. It is understood that in other embodiments, the unlocking mechanism 113 can also unlock the armrest screen 20 by directly pushing it, or by eliminating the magnetic attraction between the armrest arm 11 and the armrest screen 20; these will not be elaborated upon here.

[0050] As shown in Figure 5, in one embodiment, the unlocking mechanism 113 includes a motor 1131, a first worm 1132, a worm wheel 1133, a second worm 1134, and a motor base 1135. The motor 1131, the first worm 1132, and the worm wheel 1133 are all mounted on the motor base 1135, which is slidably connected to the armrest 11. The second worm 1134 is fixedly disposed relative to the armrest 11. The first worm 1132 is connected to both the motor 1131 and the worm wheel 1133 via transmission. The second worm 1134 is disposed on the center line (or centerline) of the worm wheel 1133 (i.e., the second worm 1134 passes through the center hole of the worm wheel 1133, and the axis of the second worm 1134 coincides with the axis of the worm wheel 1133), and is screwed (i.e., threadedly engaged) with the worm wheel 1133 (i.e., the internal thread of the center hole of the worm wheel 1133). When the unlocking mechanism 113 is working, the motor 1131 starts and drives the first worm gear 1132 to rotate. The meshing between the first worm gear 1132 and the worm wheel 1133 drives the rotation of the worm wheel 1133. Due to the threaded engagement between the worm wheel 1133 and the second worm gear 1134, and the second worm gear 1134 being fixed relative to the armrest 11, action and reaction forces allow the motor mount 1135 to drive the motor 1131, the first worm gear 1132, and the worm wheel 1133 to slide on the armrest 11. During this process, the motor mount 1135 can push the push rod 1123 on the ejection mechanism 112. Here, a bent arm 11351 is formed on the motor base 1135, and a roller 11231 is rotatably connected to the push rod 1123. By utilizing the structural shape of the bent arm 11351, when the motor base 1135 slides on the armrest 11, the bent arm 11351 can push the roller 11231 on the push rod 1123, so as to finally realize the forced push of the push protrusion 1121 on the armrest screen 20 and release the locking of the armrest screen 20 on the armrest 11.

[0051] In summary, when a user needs to remove the armrest screen 20 from the armrest body 10, they can first unfold the armrest panel 12 from the armrest arm 11, and then touch the virtual unlock button on the hidden screen 22 of the armrest screen 20 to activate the unlocking mechanism 113 and lift the armrest screen 20 from the armrest arm 11 through the pop-out mechanism 112. This allows the user to easily grasp the armrest screen 20 and pull it off the armrest arm 11. When the user needs to put the armrest screen 20 back onto the armrest body 10, they can first align the slot 23 on the armrest screen 20 with the claw 111, insert it, and lock it onto the armrest arm 11. Then, they can press the armrest screen 20 until it is attracted and locked by the armrest arm 11. Finally, the armrest panel 12 can be folded back onto the armrest arm 11.

[0052] As shown in Figures 1, 2, 7, and 8, this application also provides a seat 200, including the aforementioned seat armrest 100. Here, the armrest screen 20 within the armrest 100 is interactive and enables automatic control of the seat 200. It should be noted that the seat 200 can specifically be an aircraft seat, which can be automatically adjusted under the control of the armrest screen 20 to achieve seat posture adjustments such as backrest angle adjustment, seat fore-and-aft position adjustment, leg rest adjustment, seat cushion tilt angle adjustment, and headrest adjustment, or to control seat heating, ventilation, and massage functions.

[0053] It should be noted that the seat armrest 100 of this application can also be flipped (e.g., flipped upwards) on the seat 200, and the seat armrest 100 can be folded up on the seat 200. Here, as shown in Figure 6, in order to ensure the power supply to the armrest screen 20 in the seat armrest 100, the power cord 210 that supplies power to the armrest screen 20 can be arranged at the location of the rotating shaft 110 of the seat armrest 100 that realizes the upward flipping function, so that the upward flipping of the seat armrest 100 will not affect the power cord 210. This will not be elaborated here.

[0054] This application also provides a vehicle including the aforementioned seat 200. Here, the armrest screen 20 in the armrest 100 of the seat 200, in addition to controlling the functions of the seat 200 itself, can also control entertainment functions such as air conditioning adjustment, music playback, and video playback, thus greatly enhancing the passenger's user experience and bringing them a more pleasant mood and sense of well-being. It should be noted that the working principle of how the armrest screen 20 controls the corresponding functions can adopt conventional methods of existing technology, and will not be elaborated upon here.

[0055] As shown in Figures 6 and 7, in one embodiment, the number of seats 200 is configured to be multiple, with at least two seats 200 arranged side by side, and the two armrests 100 on the two side-by-side seats 200 facing each other. Thus, when the armrest panels 12 of the armrests 100 on the two side-by-side seats 200 are unfolded, they can be used as small tables for computer work, dining, and simple entertainment. When both armrest panels 12 are folded down, it does not affect the user's passage between the two side-by-side seats 200, thereby further improving the user experience.

[0056] The seat armrest, seat, and vehicle provided in this application embodiment can expand the function of the seat armrest by flipping the armrest panel outward, thereby increasing the headrest width of the seat armrest. During this process, the armrest screen can ensure the interaction between the armrest screen and the user through automatic switching between a visible screen and a hidden screen, so as to facilitate the user's operation of the armrest screen and improve the user experience.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] Those skilled in the art should recognize that the above embodiments are only used to illustrate this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the scope of this application fall within the scope of protection claimed in this application.
