DETAILED DESCRIPTION

[0039] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] It should be noted that when an element is referred to as being “provided on” another element, it may be directly provided on the other element or there may be an intermediate element. When an element is considered to be “provided on” another element, it may be directly provided on the other element or there may be an intermediate element. When an element is considered to be “fixed to” another element, it may be directly fixed to the other element or there may be an intermediate element.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] like Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, a chair armrest provided by an embodiment of the present application includes an armrest body 10 and an armrest screen 20. The armrest body 10 includes an armrest arm 11 and an armrest panel 12. The armrest panel 12 is movably connected to the armrest arm 11. The armrest screen 20 is limitedly connected to the armrest body 10. The armrest screen 20 includes a visible screen 21 and a hidden screen 22. The armrest panel 12 has a folded state and an unfolded state. In the folded state, the armrest panel 12 is arranged above the armrest arm 11 and abuts against the armrest arm 11 for a limited position. The armrest screen 20 can interact through the visible screen 21. In the unfolded state, the armrest panel 12 is arranged on the outside of the armrest arm 11 and abuts against the armrest arm 11 for a limited position. The armrest screen 20 can interact through the hidden screen 22. Here, the armrest panel 12 can be connected to the armrest arm 11 specifically through a hidden hinge.

[0043] As can be seen from the above, the seat armrest 100 of the present application can expand its functions by flipping the armrest panel 12 outward, thereby increasing the pillow width of the seat armrest 100. During this process, the armrest screen 20 can automatically switch between the visible screen 21 and the hidden screen 22 to ensure interaction between the armrest screen 20 and the user, thereby facilitating the user's control of the armrest screen 20 and improving the user experience. It should be noted that the width of the armrest panel 12 of the present application is the same as the width of the armrest arm 11. Therefore, when the armrest panel 12 is in the unfolded state, the pillow width of the seat armrest 100 can be doubled.

[0044] like Figure 1 、 Figure 2 、 Figure 7 and Figure 8As shown, 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 driven by the armrest panel 12. Along the width of the armrest body 10, the visible screen 21 on the armrest screen 20 is smaller than the hidden screen 22. That is, when the armrest panel 12 is folded, the armrest screen 20 is also folded, and accordingly, the visible screen 21 of the armrest screen 20 specifically refers to 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 accordingly, the hidden screen 22 of the armrest screen 20 specifically refers to the screen of the armrest screen 20 in the unfolded state. Here, the armrest screen 20 can be a flexible screen similar to a foldable screen mobile phone, and the interactive interface on the armrest screen 20 can automatically switch back and forth between the visible screen 21 and the hidden screen 22.

[0045] It should be noted that the armrest screen 20 is partially embedded in the armrest panel 12 and connected to the armrest panel 12, so that the user can simultaneously drive the armrest screen 20 to unfold when the armrest panel 12 is flipped outward, thereby meeting the need for the armrest panel 12 to drive the armrest screen 20 to fold or unfold. Here, the portion of the armrest screen 20 embedded in the armrest panel 12 can be connected to the armrest panel 12 by magnetic attraction or tight fit, so that the armrest screen 20 can be subsequently removed from the armrest body 10 as a whole.

[0046] In one embodiment, the hidden screen 22 is mounted on the armrest 11 and is detachably connected to the armrest body 10. In other words, the armrest screen 20 can be completely detached from the armrest body 10 before interaction, which further facilitates the user's control of the armrest screen 20.

[0047] It should be noted that the armrest screen 20 is provided with a power interface on the part located at the armrest arm 11, and accordingly, the armrest arm 11 is provided with a PIN pin (not shown) matching the power interface (not shown); when the armrest screen 20 is assembled to the armrest body 10, the PIN pin can be electrically connected to the armrest screen 20 through the power interface, so that the armrest arm 11 can be used to charge the armrest screen 20 on the one hand, and on the other hand, it can also realize the transmission of data of the armrest screen 20, thereby creating conditions for the subsequent automatic unlocking of the armrest screen 20.

[0048] In one embodiment, one end of the hidden screen 22 is abutted against the armrest 11, and the hidden screen 22 can be magnetically locked 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 element, and the hidden screen 22 is equipped with a ferromagnetic element that can be attracted by the magnetic element. The magnetic element attracts the ferromagnetic element, thereby magnetically locking the hidden screen 22 to the armrest 11.

[0049] It should be noted that, since the seat armrest 100 is horizontal when used in the seat 200, the armrest screen 20 is also horizontal when assembled on the armrest body 10. The armrest screen 20 can also be placed flat on the armrest arm 11 under the action of its own gravity. Therefore, the magnetic attraction force of the armrest arm 11 when locking the armrest screen 20 can be set to be very small.

[0050] like Figure 3 As shown, one of the hidden screen 22 and the armrest 11 is provided with a slot 23, while the other is provided with a protruding claw 111. When one end of the hidden screen 22 is abutted against the armrest 11, the claw 111 is inserted into the slot 23 and can swing relative to the slot 23. Furthermore, when the hidden screen 22 is locked by the armrest 11, the claw 111 abuts against the wall 231 of the slot 23 to limit its position. In other words, the claw 111 has a certain amount of travel within the slot 23 to allow it to tilt. In other words, the engagement between the claw 111 and the slot 23 achieves the locking contact between the hidden screen 22 and the armrest 11, and limits the tilting angle of the hidden screen 22 when it is lifted from the armrest 11. Here, the slot 23 is provided on the hidden screen 22, while the claw 111 is provided on the armrest 11. It is understood that in other embodiments, the card slot can also be set on the hidden screen 22, and the claws 111 can be set on the armrest 11. It should be noted that the number and arrangement of the claws 111 can be specifically set according to the needs of use, and will not be elaborated here.

[0051] like Figure 4 As shown, in one embodiment, the armrest 11 is provided with a pop-up mechanism 112, which can push the armrest screen 20 to tilt the armrest screen 20 that is stuck on the armrest 11, and release the lock of the armrest screen 20. In other words, the pop-up mechanism 112 pushes the armrest screen 20 to automatically tilt it away from the armrest 11. At the same time, the power interface on the armrest screen 20 can be disengaged from the PIN pin on the armrest 11, which makes it easier for the user to take it, thereby further facilitating the user to remove the armrest screen 20 from the armrest 11.

[0052] It should be noted that when the pop-up mechanism 112 pushes the armrest screen 20 to tilt up on the armrest arm 11, the force applied by the pop-up mechanism 112 to push up the armrest screen 20 needs to be greater than the sum of the magnetic attraction force when the armrest screen 20 is locked to the armrest arm 11 and the force when the armrest screen 20 is connected to the armrest panel 12.

[0053] like Figure 4 As shown, in one embodiment, the pop-up mechanism 112 includes a pushing protrusion 1121, an elastic member 1122, and a push rod 1123. The pushing protrusion 1121 is slidably connected to the armrest 11 and can abut against the armrest screen 20. The elastic member 1122 is pre-compressed and accommodated in the pushing protrusion 1121. One end of the elastic member 1122 abuts against the inner wall of the pushing protrusion 1121, and the other end abuts against the armrest 11. One end of the push rod 1123 abuts against the inner wall of the pushing protrusion 1121. In this way, the pop-up mechanism 112 can utilize the elastic force of the elastic member 1122 on the pushing protrusion 1121 to push the armrest screen 20 through the pushing protrusion 1121, and the push rod 1123 can forcibly push the pushing protrusion 1121 to unlock the armrest screen 20 from the armrest 11. Here, the number of the elastic members 1122 may be one, two, or even more. Specifically, the elastic member 1122 may be configured as a compression spring, a rubber sleeve, or other accessories with high elasticity.

[0054] like Figure 5 As shown, in one embodiment, the armrest arm 11 is further 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 of the armrest screen 20. In other words, the armrest screen 20 can control the activation of the unlocking mechanism 113 and use the unlocking mechanism 113 to control the unlocking of the armrest screen 20. In this way, the unlocked armrest screen 20 can automatically tilt up under the push of the pop-up mechanism 112, 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 unlocking button (not shown). The user can trigger the armrest screen 20 by clicking the virtual unlocking 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, thereby controlling the activation of the unlocking mechanism 113.

[0055] In one embodiment, the unlocking mechanism 113 can unlock the armrest screen 20 by providing power to the push rod 1123 on the pop-up mechanism 112, and using the push rod 1123 to forcibly push the push protrusion 1121. It is understood that in other embodiments, the unlocking mechanism 113 can also unlock the armrest screen 20 by directly pushing the armrest screen 20, or by eliminating the magnetic attraction of the armrest arm 11 to the armrest screen 20, which will not be explained in detail here.

[0056] like Figure 5 As shown, 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 installed on the motor base 1135, and the motor base 1135 is slidingly connected to the armrest 11; the second worm 1134 is fixed relative to the armrest 11, wherein the first worm 1132 is respectively connected to the motor 1131 and the worm wheel 1133, and the second worm 1134 is arranged on the center line of the worm wheel 1133 and is screwed to the worm wheel 1133. In this way, when the unlocking mechanism 113 is working, the motor 1131 is started to drive the first worm 1132 to rotate. The meshing cooperation between the first worm 1132 and the worm wheel 1133 can realize the rotation driving of the worm wheel 1133. Due to the threaded cooperation between the worm wheel 1133 and the second worm 1134, the second worm 1134 is fixed relative to the armrest 11. In this way, the action force and reaction force can be used to realize the motor base 1135 driving the motor 1131, the first worm 1132 and the worm wheel 1133 thereon to slide on the armrest 11. During this process, the motor base 1135 can push the push rod 1123 on the pop-up mechanism 112. Here, a bending arm 11351 is formed on the motor base 1135, and a roller 11231 is rotatably connected to the push rod 1123. Utilizing the structural shape of the bending arm 11351, when the motor base 1135 slides on the armrest arm 11, the bending arm 11351 can push the roller 11231 on the push rod 1123, thereby ultimately achieving the forced pushing of the armrest screen 20 by the pushing protrusion 1121, and releasing the lock of the armrest screen 20 on the armrest arm 11.

[0057] In summary, when the user needs to remove the armrest screen 20 from the armrest body 10, the user can first unfold the armrest panel 12 from the armrest arm 11, and then touch the virtual unlocking button on the hidden screen 22 of the armrest screen 20 with the human hand to activate the unlocking mechanism 113 and lift the armrest screen 20 from the armrest arm 11 through the pop-up mechanism 112, so that the human hand can easily grab the armrest screen 20 to pull the armrest screen 20 out of the armrest arm 11; when the user needs to put the armrest screen 20 back on the armrest body 10, the human hand can first align the card slot 23 on the armrest screen 20 with the card claw 111 and insert it and lock it to the armrest arm 11, and then press the armrest screen 20 with the human hand until the armrest screen 20 is adsorbed and locked by the armrest arm 11, and finally the armrest panel 12 can be folded onto the armrest arm 11.

[0058] like Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, the present application also provides a seat 200 including the aforementioned armrest 100. Here, the armrest screen 20 in the armrest 100 is interactive and enables automatic control of the seat 200. It should be noted that the seat 200 may specifically be an airline seat, and the adjustment functions of the seat 200 can be automatically adjusted under the control of the armrest screen 20.

[0059] It should be noted that the armrest 100 of the present application can be flipped up on the seat 200 as a whole, and the armrest 100 can be folded on the seat 200. Figure 6 As shown, in order to ensure the power supply to the armrest screen 20 in the seat armrest 100, the power cord 210 for supplying power to the armrest screen 20 can be arranged at the position of the rotating shaft 110 on the seat armrest 100 for realizing the flip-up function, so that the flip-up of the seat armrest 100 will not affect the power cord 210, which will not be elaborated here.

[0060] This application also provides a vehicle including the aforementioned seat 200. Here, the armrest screen 20 in the armrest 100 of the seat 200 not only controls the functions of the seat 200 itself but also controls vehicle entertainment programs such as air conditioning, music playback, and video playback. This significantly enhances the passenger experience and brings a greater sense of pleasure and well-being. It should be noted that the operating principle of how the armrest screen 20 controls the corresponding functions can be implemented using conventional methods in the prior art and will not be elaborated upon here.

[0061] like Figure 6 、 Figure 7As shown, in one embodiment, the number of seats 200 is configured as a plurality, with at least two seats 200 arranged side by side. Furthermore, the two armrests 100 on the two side-by-side seats 200 are arranged 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 the armrest panels 12 are folded, they do not affect the user's ability to enter and exit between the two side-by-side seats 200, further enhancing the user experience.

[0062] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, 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.
