DETAILED DESCRIPTION

[0039] The following will be combined with the 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 described embodiments 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 creative work 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 a central 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 a central element at the same time. When an element is considered to be "fixed to" another element, it may be directly fixed to the other element or there may be a central element at the same time.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related 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, and 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, and the armrest screen 20 can interact through the hidden screen 22. Here, the armrest panel 12 can be specifically connected to the armrest arm 11 through an invisible hinge.

[0043] As can be seen from the above, the seat armrest 100 of the present application can achieve the expansion of the function of the seat armrest 100 by flipping the armrest panel 12 outward, so that the pillow width of the seat armrest 100 can be increased. In this process, the armrest screen 20 can ensure the interaction between the armrest screen 20 and the user by automatically switching between the visible screen 21 and the hidden screen 22, so as to facilitate the user's control of the armrest screen 20, thereby improving the user's 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, so that 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 under the drive 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 to say, when the armrest panel 12 is in a folded state, the armrest screen 20 is also in a folded state, and accordingly, the visible screen 21 of the armrest screen 20 is specifically the screen of the armrest screen 20 in a folded state; when the armrest panel 12 is in an unfolded state, the armrest screen 20 is also in an unfolded state, and accordingly, the hidden screen 22 of the armrest screen 20 is specifically the screen of the armrest screen 20 in an unfolded state. Here, the armrest screen 20 can be specifically a flexible screen similar to a folding screen mobile phone, and the interface for interaction 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 drive the armrest screen 20 to unfold while flipping the armrest panel 12 outward, which can meet the use requirements of the armrest panel 12 driving the armrest screen 20 to fold or unfold. Here, the part 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 as to meet the use requirements of subsequently removing the armrest screen 20 from the armrest body 10 as a whole.

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

[0047] It should be noted that the armrest screen 20 is provided with a power-on interface on the part located at the armrest arm 11, and correspondingly, the armrest arm 11 is provided with a PIN pin (not shown) matching the power-on 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-on 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 clamped against the armrest 11, and the hidden screen 22 can be locked by the armrest 11 in a magnetic way. This makes it easy to remove and assemble the hidden screen 22 on the armrest 11. Here, the armrest 11 is equipped with a magnetic attraction component, and the hidden screen 22 is equipped with a ferromagnetic component that can be attracted by the magnetic attraction component. By using the magnetic attraction component to attract the ferromagnetic component, the hidden screen 22 can be locked by the armrest 11 in a magnetic way.

[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, and the other is formed with a protruding claw 111; when one end of the hidden screen 22 is clamped on the armrest 11, the claw 111 is inserted into the slot 23, and the claw 111 can swing relative to the slot 23; and when the hidden screen 22 is locked by the armrest 11, the claw 111 is abutted against the slot wall 231 of the slot 23 to limit the position. That is, the claw 111 has a turning stroke in the slot 23. That is, through the cooperation between the claw 111 and the slot 23, the clamping between the hidden screen 22 and the armrest 11 is specifically realized, and the turning angle of the hidden screen 22 when it is tilted from the armrest 11 can be limited. Here, the slot 23 is set on the hidden screen 22, and the claw 111 is set on the armrest 11. It is understandable that in other embodiments, the card slot can also be set on the hidden screen 22, and the claw 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, which will not be elaborated here.

[0051] like Figure 4 As shown, in one embodiment, a pop-up mechanism 112 is provided on the armrest arm 11, and the pop-up mechanism 112 can push up the armrest screen 20, so that the armrest screen 20 stuck on the armrest arm 11 is tilted up, and the armrest screen 20 is unlocked. In other words, by pushing up the armrest screen 20 with the pop-up mechanism 112, the armrest screen 20 can be automatically tilted up from the armrest arm 11, and at the same time, the power interface on the armrest screen 20 can be disengaged from the PIN pin on the armrest arm 11, which is convenient for users to take it, and further convenient for users to remove the armrest screen 20 from the armrest arm 11.

[0052] It should be noted that when the pop-up mechanism 112 pushes the armrest screen 20 to rise 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 push-up protrusion 1121, an elastic member 1122, and a push rod 1123. The push-up protrusion 1121 is slidably connected to the armrest arm 11 and can abut against the armrest screen 20. The elastic member 1122 is received in the push-up protrusion 1121 in a pre-compressed manner, and one end of the elastic member 1122 abuts against the inner wall of the push-up protrusion 1121, and the other end abuts against the armrest arm 11. One end of the push rod 1123 abuts against the inner wall of the push-up protrusion 1121. In this way, the pop-up mechanism 112 can use the elastic push of the elastic member 1122 on the push-up protrusion 1121 to push the armrest screen 20 through the push-up protrusion 1121, and the push rod 1123 can forcibly push the push-up protrusion 1121 to unlock the armrest screen 20 locked on the armrest arm 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, an unlocking mechanism 113 is further provided on the armrest arm 11, and the unlocking mechanism 113 is electrically connected to the armrest screen 20, and the unlocking mechanism 113 can be started 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 unlocking mechanism 113 to start, and use the unlocking mechanism 113 to control the unlocking of the armrest screen 20, so that the unlocked armrest screen 20 can automatically tilt up under the push of the pop-up mechanism 112, which can further facilitate the user to remove the armrest screen 20 from the armrest body 10. Here, a virtual unlocking button (not shown) is provided on the armrest screen 20, and 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-on interface and control the unlocking mechanism 113 to start.

[0055] In one embodiment, the unlocking mechanism 113 can provide power to the push rod 1123 on the pop-up mechanism 112, and use the push rod 1123 to forcibly push the push protrusion 1121 to achieve the purpose of driving the armrest screen 20 to unlock. It can be 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 to unlock the armrest screen 20, which will not be elaborated 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 seat 1135, the motor 1131, the first worm 1132 and the worm wheel 1133 are all installed on the motor seat 1135, and the motor seat 1135 is slidably connected to the armrest 11; the second worm 1134 is fixedly arranged relative to the armrest 11, wherein the first worm 1132 is respectively connected to the motor 1131 and the worm wheel 1133 in transmission, 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, and the second worm 1134 is fixed relative to the armrest 11, the action force and reaction force can be used to realize that the motor seat 1135 drives the motor 1131, the first worm 1132 and the worm wheel 1133 thereon to slide on the armrest 11. In this process, the motor seat 1135 can push the push rod 1123 on the pop-up mechanism 112. Here, a bending arm 11351 is formed on the motor seat 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 seat 1135 slides on the armrest arm 11, the bending arm 11351 can push up the roller 11231 on the push rod 1123, thereby finally achieving the forced pushing up 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 armrest panel 12 can be unfolded from the armrest arm 11 first, and then the virtual unlocking button on the hidden screen 22 of the armrest screen 20 can be touched by 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 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 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 by hand until the armrest screen 20 is absorbed 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 seat armrest 100 described above. Here, the armrest screen 20 in the seat armrest 100 can be interactive and realize automatic control of the seat 200. It should be noted that the seat 200 can be specifically an aviation seat, and the adjustment function of the seat 200 can be automatically adjusted under the control of the armrest screen 20.

[0059] It should be noted that the seat armrest 100 of the present application can be turned up on the seat 200 as a whole, and the seat 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 for realizing the flip-up function on the seat armrest 100, so that the flipping up of the seat armrest 100 will not affect the power cord 210, which will not be elaborated here.

[0060] The present application also provides a vehicle, including the seat 200 described above. Here, the armrest screen 20 in the seat armrest 100 on the seat 200 can control the functions of the seat 200 itself, and the armrest screen 20 can also control the air conditioning, music playing, video playing and other entertainment items on the vehicle, which can greatly improve the passenger's experience and bring a more pleasant mood and happiness to the passengers. It should be noted that the working principle of how the armrest screen 20 controls the corresponding functions can adopt the conventional method of the prior art, which will not be elaborated here.

[0061] like Figure 6 , Figure 7As shown, in one embodiment, the number of the seats 200 is configured as multiple, at least two seats 200 of the multiple seats 200 are arranged side by side, and the two seat armrests 100 on the two seats 200 arranged side by side are arranged face to face. In this way, when the armrest panels 12 of the seat armrests 100 on the two seats 200 arranged side by side are unfolded, they can be used as a small table for computer office, dining and simple entertainment measures. When the two armrest panels 12 are folded, it does not affect the passability of users when entering and exiting between the two seats 200 arranged side by side, which can further improve the user's use experience.
