Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0041] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] like Figures 1 to 7 As shown, in one embodiment of the present application, an armrest with a seat function is provided, the armrest includes an armrest body 51, the armrest body 51 is arranged in the elevator car 50, the armrest also includes a seat panel 10, a locking mechanism 20, a rebound mechanism 30 and a rotating mechanism 40 installed on the inner wall of the car 50, wherein the rotating mechanism 40 is installed below the armrest body 51.

[0043] Further, see Figure 1 and Figure 2 As shown, the seat panel 10 is installed on the rotating mechanism 40, and is used to drive the seat panel 10 to flip relative to the inner wall of the car 50, so that the seat panel 10 can switch back and forth between a folded state and an unfolded state relative to the inner wall of the car 50. The rebound mechanism 30 is installed in the rotating mechanism 40, and is used to drive the seat panel 10 to automatically restore from the unfolded state to the folded state; wherein, the folded state refers to the state in which the seat panel 10 is parallel to the inner wall of the car 50. At this time, the seat panel 10 occupies a small space in the car 50 and does not affect the normal use of the elevator at all; the unfolded state refers to the state in which the seat panel 10 is perpendicular to the inner wall of the car 50. At this time, the seat panel 10 is horizontally arranged to provide a seat for personnel; of course, in other embodiments, the unfolded state can also be a state in which the seat panel 10 is at an acute angle or an obtuse angle to the inner wall of the car 50, and its specific angle can be specifically set according to the comfort and stability of the personnel sitting, and is not limited here.

[0044] Furthermore, the locking mechanism 20 is installed on the seat panel 10. When the seat panel 10 is in a folded state, the locking mechanism 20 locks the seat panel 10 on the armrest body 51; when the seat panel 10 is in an unfolded state, the seat panel 10 is set at an angle with the inner wall of the car 50 for people to sit on.

[0045] Specifically, the armrest with a seat function in the embodiment of the present application, when needed, unlocks the locking device so that the seat panel 10 is separated from the armrest body 51, and then, the seat panel 10 is pulled to flip over, at this time, the seat panel 10 is gradually unfolded until it is fully unfolded to provide a seat for the person; after use, the person leaves, and the seat panel 10 automatically returns to the folded state under the action of the rebound mechanism 30; its use operation is time-saving and labor-saving, convenient and fast, so in the event of an emergency, if the person sits on the seat panel 10, and the seat panel 10 is installed on the inner wall of the car 50 through the slewing mechanism 40, it is firmly and reliably fixed, and the problem of temporary sliding is avoided. If the person does not sit on the seat panel 10, the rebound mechanism 30 automatically restores the seat panel 10 to the folded state, that is, at this time, the locking mechanism 20 locks and fixes the seat panel 10 on the armrest body 51, so that the entire armrest is fixed stably and reliably, and the problem of temporary sliding can also be prevented, thus solving the unsafe hidden dangers of seats in existing elevators.

[0046] In another embodiment of the present application, see Figure 6 and Figure 7 As shown, the swivel mechanism 40 of the armrest with seat function provided includes a swivel support column 41 and a mounting seat 42 installed on the inner wall of the car 50, one end of the swivel support column 41 is hinged to the mounting seat 42, a horizontal plate 43 is provided on the mounting seat 42, and the horizontal plate 43 is located below the swivel support column 41. When the seat panel 10 is in the unfolded state, the swivel support column 41 abuts against the horizontal plate 43 to limit the swivel support column 41 from excessive downward rotation. The seat panel 10 is installed on the swivel support column 41.

[0047] Specifically, the rotation of the rotating support column 41 relative to the mounting base 42 drives the seat panel 10 to flip relative to the inner wall of the car 50, thereby realizing the switching of the seat panel 10 between the folded state and the unfolded state. When the rotating support column 41 rotates and presses against the horizontal plate 43, the rotating support column 41 cannot continue to rotate. At this time, the seat panel 10 is in the unfolded state. The horizontal plate 43 can prevent the rotating support column 41 from rotating downward excessively, thereby preventing the seat panel 10 from tilting downward excessively, which makes it impossible for people to sit stably on the seat panel 10.

[0048] Furthermore, the specific relative setting between the horizontal plate 43 and the rotating support column 41 can be set according to the angle between the seat panel 10 and the inner wall of the car 50 when in the unfolded state, and it is only necessary to ensure that the seat panel 10 can stably support the person sitting on the seat panel 10.

[0049] Furthermore, the number of the swivel mechanisms 40 can be two, three or more, and the swivel mechanisms 40 are evenly spaced along the width direction of the seat panel 10, so that the seat panel 10 is supported by the swivel mechanisms 40, the supporting force is greater, and the structure of the entire seat is more stable and reliable.

[0050] Furthermore, the mounting base 42 is fixed on the car 50 by screws, and the installation operation is simple, convenient and fast, and the stability and reliability are good.

[0051] Furthermore, the seat panel 10 includes a plurality of seat strips 15, and the seat strips 15 are all passed through the rotating support column 41. The seat strips 15 are arranged in parallel and spaced apart, and are evenly spaced apart along the length direction of the rotating support column 41. In this way, when a person sits on the seat panel 10, the gaps between the seat strips 15 can be ventilated and breathable. The seat has good ventilation and air permeability, and the person sitting comfortably has good air permeability.

[0052] Furthermore, the surface of each seat bar 15 is covered with a plastic layer, which facilitates the cleaning of the seat.

[0053] In another embodiment of the present application, see Figure 6 and Figure 7 As shown, the swivel mechanism 40 of the armrest with seat function provided also includes a hinge shaft 45, and two vertical plates 44 are further arranged on the mounting seat 42, the two vertical plates 44 are arranged in parallel and spaced apart, and a receiving groove 441 is formed between the two vertical plates 44, the two vertical plates 44 are located directly above the horizontal plate 43, and the two vertical plates 44 are both provided with a first hinge hole 442, and the end of the rotating support column 41 is provided with a second hinge hole 411, and the end of the rotating support column 41 is located in the receiving groove 441, and the hinge shaft 45 is penetrated through the first hinge hole 442 and the second hinge hole 411.

[0054] Specifically, the two vertical plates 44 provide a mounting base for the hinge of the rotating support column 41, which plays a role in supporting the rotating support column 41. The hinge shaft 45 rotates in the first hinge hole 442 and the second hinge hole 411, thereby realizing the rotation of the rotating support column 41 relative to the inner wall of the car 50, and then realizing the flipping of the seat panel 10 relative to the inner wall of the car 50.

[0055] Furthermore, the horizontal plate 43 is located between the two vertical plates 44, and the two ends of the horizontal plate 43 are respectively connected to the two vertical plates 44, and the horizontal plate 43 and the two vertical plates 44 are integrally formed and U-shaped, so that the installation support of the rotating support column 41 is more stable and reliable, and can also meet the needs of heavy people.

[0056] In another embodiment of the present application, see Figure 6 and Figure 7 As shown, the end of the rotating support column 41 of the armrest with a seat function is provided with a block 412, the second hinge hole 411 is provided on the block 412, and the side of the block 412 close to the vertical plate 44 is provided parallel to the vertical plate 44. Specifically, when the seat panel 10 and the inner wall of the car 50 are in a vertical state, that is, in an unfolded state, the bottom surface of the block 412 is completely in contact with the horizontal plate 43, and the horizontal plate 43 and the rotating support column 41 are in surface-to-surface contact, so that the fixing reliability of the rotating support column 41 is good, and the supporting capacity of the entire seat panel 10 is also better, and it can also meet the riding of heavy weight people.

[0057] In another embodiment of the present application, see Figure 6 and Figure 7 As shown, the swivel mechanism 40 of the armrest with a chair function provided also includes a shell 46, on which an escape groove 461 is provided, the shell 46 is covered on the mounting seat 42, the horizontal plate 43 and the two vertical plates 44 are both located in the shell 46, and the rotating support column 41 extends from the escape groove 461 and rotates in the escape groove 461. Specifically, the shell 46 is exposed on the mounting seat 42, so that the horizontal plate 43 and the vertical plate 44 and other components are hidden in the shell 46, so that the safety and reliability of the whole structure are better, and the appearance is more beautiful; in addition, the rotating support column 41 extends from the escape groove 461 to avoid interference between the shell 46 and the rotating support column 41, thereby ensuring the normal use of the chair.

[0058] In another embodiment of the present application, see Figure 6 and Figure 7 As shown, the opposite sides of the housing 46 of the armrest with a seat function are provided with fixing holes 462, and the slewing mechanism 40 further includes two fixing columns 47, which are respectively mounted on the two end surfaces of the hinge shaft 45, and the two fixing columns 47 are respectively penetrated in the fixing holes 462, and the diameters of the fixing columns 47 and the fixing holes 462 are both smaller than the diameter of the hinge shaft 45. The hinge shaft 45 is axially fixed by the step surface formed at the fixing columns 47 and the end surface of the hinge shaft 45, and the fixing method has a simple structure.

[0059] In another embodiment of the present application, see Figure 6 and Figure 7As shown, the hinge shaft 45 of the armrest with seat function is fixedly connected to the second hinge hole 411, the rebound mechanism 30 includes a connecting rod 31, a semicircular sheet 32, a pressing sheet 33, a first spring 34 and a base 35, a pressing sheet groove 443 is opened on the vertical plate 44, and the pressing sheet groove 443 is located below the first hinge hole 442, one end of the pressing sheet 33 extends into the pressing sheet groove 443 and can move up and down in the pressing sheet groove 443, and the base 35 is installed on the mounting seat 42 and is located at the pressing sheet Below the seat panel 10, the first spring 34 is installed between the pressure plate 33 and the base 35, and the two ends of the first spring 34 are respectively pressed against the pressure plate 33 and the base 35; one end of the connecting rod 31 is connected to the hinge shaft 45 and is vertically arranged to the hinge shaft 45, and the other end of the connecting rod 31 is connected to the semicircular piece 32. In the process of the seat panel 10 changing from a folded state to an unfolded state, the connecting rod 31 rotates downward so that the arc surface of the semicircular piece 32 gradually squeezes the pressure plate 33, thereby compressing the first spring 34.

[0060] Specifically, when the seat panel 10 needs to be unfolded, it is only necessary to pull the seat panel 10 downward and rotate it. At this time, the connecting rod 31 also rotates downward with the hinge shaft 45, and the semicircular piece 32 also rotates downward accordingly, so that the semicircular piece 32 compresses the pressure piece 33 downward, thereby compressing the first spring 34; and when the person on the seat panel 10 leaves, the first spring 34 returns to its natural state, pushes the semicircular piece 32 upward, thereby driving the connecting rod 31 to flip upward, and then drives the hinge shaft 45 to rotate upward, thereby automatically restoring the seat panel 10 to the folded state. In this way, the automatic resetting of the seat panel 10 is completed.

[0061] Furthermore, two rebound mechanisms 30 are provided in the rotating mechanism 40, and the two rebound mechanisms 30 are respectively arranged between two vertical plates 44 and two opposite inner walls of the corresponding outer shell 46, so that the rebound mechanism 30 drives the seat panel 10 to reset more stably and reliably.

[0062] In another embodiment of the present application, see Figure 3 , Figure 4 and Figure 5As shown, the locking mechanism 20 of the armrest with seat function provided includes a rotating button 21, a connecting rope 22, a second spring 23 and a locking block 24 plugged into and matched with the locking groove 512 on the armrest body 51, a mounting cavity 11 is provided in the seat panel 10, and a mounting hole 12 connected to the mounting cavity 11 is provided on the surface of the inner wall of the seat panel 10 facing away from the car 50, the rotating button 21 is installed in the mounting cavity 11 and extends out of the mounting hole 12, a sliding hole 13 is provided on the side of the seat panel 10 facing the armrest body 51, the locking block 24 and the second spring 23 are located in the sliding hole 13, the two ends of the second spring 23 are respectively pressed against the locking block 24 and the bottom surface of the sliding hole 13, the bottom surface of the sliding hole 13 is provided with a connecting hole 14, one end of the connecting rope 22 is connected to the locking block 24, and the other end of the connecting rope 22 is connected to the rotating button 21 after passing through the connecting hole 14, and the connecting rope 22 is rotated with the rotating button 21, thereby being wound around the rotating button 21.

[0063] Specifically, when the locking mechanism 20 is in a locked state, the locking block 24 is inserted into the locking groove 512, so that the seat panel 10 is locked on the armrest body 51, so that the seat panel 10 and the armrest body 51 are connected as a whole, avoiding relative movement and causing unsafe accidents; and when the locking mechanism 20 needs to be unlocked, the rotating button 21 is rotated so that the connecting rope 22 is wound around the rotating button 21, thereby driving the locking block 24 to compress the second spring 23 and retract it into the sliding hole 13. At this time, the locking block 24 is slotted into the armrest body 51, so that the seat panel 10 is separated from the armrest body 51, thereby facilitating the unfolding of the seat panel 10; when the rotating button 21 is released, the second spring 23 pushes the locking block 24 out of the sliding hole 13 under the action of its own spring force, thereby realizing the resetting of the locking block 24.

[0064] Furthermore, the locking block 24 is installed in the seat bar 15 at the uppermost end of the back-swivel mechanism 40, so that the upper and lower ends of the seat panel 10 are fixed, so that the seat panel 10 is fixed more stably and is safer and more reliable to use.

[0065] Furthermore, a notch 511 for accommodating the seat panel 10 is provided on the armrest body 51, and there are two locking blocks 24. The two ends of the connecting rope 22 are respectively connected to the two locking blocks 24, and the middle part of the connecting rope 22 is connected to the rotating button 21. Locking grooves 512 are provided on the opposite surfaces of the notch 511, and the two locking blocks 24 are respectively inserted into the two locking grooves 512. Moreover, when the rotating button 21 is rotated, the connecting rope 22 is wound around the rotating button 21, thereby simultaneously driving the two locking blocks 24 to exit the locking grooves 512, thereby realizing the unlocking of the locking mechanism 20.

[0066] In another embodiment of the present application, see Figure 3 , Figure 4 and Figure 5 As shown, the locking mechanism 20 of the armrest with seat function provided includes a third spring 25, and a pressing protrusion 211 is provided on the outer peripheral wall of the rotating button 21. The third spring 25 is installed between the pressing protrusion 211 and the inner wall of the installation cavity 11. When the rotating button 21 is rotated, the pressing protrusion 211 presses the third spring 25. Specifically, when the rotating button 21 is rotated, the pressing protrusion 211 presses the third spring 25; when the person releases the rotating button 21, the third spring 25 pushes the pressing protrusion 211 to reset under its own spring force, thereby realizing the automatic reset of the rotating button 21, making the use of the locking mechanism 20 more convenient and simple.

[0067] In another embodiment of the present application, see Figure 1 and Figure 2 As shown, an elevator is provided, including a car 50 and the above-mentioned handrail with seat function, and the handrail body 51 and the slewing mechanism 40 are both installed on the inner wall of the car 50.
