Description

Technical Field

[0001] This application relates to the technical field of elevator manufacturing, and particularly to a concealed handrail for a car elevator. Background Art

[0002] Elevators used in commercial and medical environments are usually equipped with fixed handrails designed to help passengers maintain balance during elevator travel. Fixed handrails are widely used in various types of elevators and are commonly adopted because of their simple structure and low cost.

[0003] However, with the continuous improvement of requirements for passenger experience and safety, the limitations of fixed handrails are becoming increasingly apparent. Especially in situations where there are many passengers or large equipment (such as hospital beds) needs to be transported, fixed handrails will occupy a certain amount of space and become obstacles, resulting in a crowded environment inside the car and low passenger comfort and safety. Summary of the Invention

[0004] To improve the comfort and safety of passengers' riding experience, this application provides a concealed handrail for a car elevator.

[0005] The concealed handrail for a car elevator provided by this application adopts the following technical solutions: A concealed handrail for a car elevator includes: An elevator frame with a concealed groove opened therein; A baffle member for opening or closing the concealed groove, and a rope member is connected to one side of the baffle member; A rope winding mechanism is connected to the end of the rope member away from the baffle member for winding or unwinding the rope member to open or close the concealed groove; A locking mechanism for locking the closed state of the concealed groove; A mounting seat is connected to the elevator frame. The mounting seat is connected with a rotational driving member. The mounting seat is rotatably connected with a connecting member. The output end of the rotational driving member is connected to one end of the connecting member, and the end of the connecting member away from the rotational driving member is connected to a handrail rod.

[0006] By adopting the above technical solution, when the handrail is not in use, the handrail is stored in the hidden groove of the elevator frame. The baffle closes the hidden groove and is fixed by the locking mechanism, keeping the interior of the elevator clean and maximizing the space. When the handrail is needed, by operating the rope winding mechanism, the rope piece is unwound, driving the baffle to open the hidden groove. Then the rotation driving piece is started, and the rotation driving piece drives the rotation of the connecting piece, so that the handrail smoothly unfolds from the hidden groove to the use position. After use, the rotation driving piece and the rope winding mechanism are operated in reverse, so that the handrail is retracted into the hidden groove, the baffle closes and locks, restoring the clean state inside the elevator. The hidden design saves space when not in use, making the interior of the elevator look more spacious, improving the aesthetics and space utilization rate of the elevator, and enhancing the comfort and safety of the passengers' riding experience.

[0007] Optionally, the top of the baffle is hinged to the elevator frame, and the locking mechanism is located at the bottom of the baffle.

[0008] By adopting the above technical solution, the hinge structure makes the opening and closing operations of the baffle more smooth and labor-saving. Passengers or maintenance personnel can easily control the movement of the baffle through the rope piece and the rope winding mechanism without additional force or complex operation steps.

[0009] Optionally, the connecting piece is arranged on the bottom wall of the hidden groove.

[0010] By adopting the above technical solution, the stability of the handrail during unfolding and retracting is improved. The bottom wall of the groove serves as a support surface, providing a firm fixing point for the connecting piece, reducing the possibility of the handrail shaking during use, and enhancing the sense of security of passengers.

[0011] Optionally, the connecting piece includes a square rod portion and a round rod portion. The square rod portion is connected to the round rod portion. One end of the square rod portion away from the round rod portion is connected to the output end of the rotation driving piece, and the square rod portion abuts against the bottom wall of the hidden groove.

[0012] By adopting the above technical solution, the square rod portion abuts against the bottom wall of the groove, providing a larger contact area and increasing the stability of the structure. The connection between the round rod portion and the square rod portion makes the connecting piece more stable when bearing torque, reducing stress concentration and improving the strength of the overall structure.

[0013] Optionally, the rope winding mechanism includes a rope winding frame, a rope winding cylinder and a rope winding driving piece. The rope winding frame is connected to the elevator frame. The rope winding cylinder is rotatably connected to the rope winding frame. The rope winding driving piece is connected to the rope winding frame. The output end of the rope winding driving piece is connected to the rope winding cylinder. One end of the rope piece away from the baffle is connected to the rope winding cylinder, and the rope piece is wound around the outer wall of the rope winding cylinder.

[0014] By adopting the above technical solution, when it is necessary to open the baffle member, the rope drive member is started, and the output end of the rope drive member drives the rope drum to rotate. When the rope drum rotates, the rope drum winds the rope member, and the baffle member rotates around the top hinge point to open the hidden groove. As the rope member continues to wind, the baffle member is fully opened, and the hidden groove is exposed, providing sufficient space for the deployment of the handrail rod. When it is necessary to close the baffle member, the rope drive member is reversely operated, the rope drum rotates in the opposite direction, and the rope drum releases the rope member, driving the baffle member to close the hidden groove. The rotation of the rope drum is accurately controlled by the rope drive member to ensure that the rope member is smoothly retracted and released, and the stability of the opening and closing of the baffle member and the passenger's use experience are improved. At the same time, the compact design of the rope mechanism, especially the combination of the rope drum and the rope frame, makes the entire mechanism occupy a small space and optimizes the internal space utilization of the elevator. Secondly, the design of the rope mechanism can adapt to elevators of different sizes and types. By adjusting the size of the rope drum and the power of the rope drive member, the use requirements of different elevators for hidden handrails can be met, and the adaptability and flexibility of the handrail use can be improved.

[0015] Optionally, the locking mechanism includes a locking drive and a locking member, the locking drive is connected to the elevator frame, the output end of the locking drive is connected to the locking member, and the locking member drives the locking member to abut against the baffle member, so that the baffle member is fixed at the hidden groove.

[0016] By adopting the above technical solution, when the hidden slot needs to be closed, the locking drive member is started, the locking drive member drives the locking member to move, and the locking member contacts the baffle member until the baffle member is completely closed and fits against the hidden slot, and the hidden slot is completely closed; when the hidden slot needs to be opened, the locking drive member is operated in reverse to disengage the locking member from the baffle member, release the locking state, and open the baffle member. The movement of the locking member is precisely controlled by the locking drive member, thereby improving the stability and safety of the baffle member in the closed state and reducing the risk of accidental opening of the hidden slot when not in use.

[0017] Optionally, the baffle member is slidably connected to a pushing member, and the pushing member slides on the baffle member through the locking mechanism. One end of the pushing member is connected to an edge sealing member, and the edge sealing member is slidably connected to the baffle member, and the peripheral wall of the edge sealing member is attached to the peripheral wall of the hidden groove.

[0018] By adopting the above technical solution, the baffle member is in a closed state, and the edge sealing member slides along the peripheral wall of the hidden groove under the drive of the pushing member. The edge sealing member fits with the peripheral wall of the hidden groove, thereby improving the sealing of the hidden groove, reducing the possibility of dust and foreign matter entering, improving the cleanliness and aesthetics of the interior of the elevator, and reducing the possibility of passengers' fingers or other body parts being caught in the gap and causing injuries during the opening and closing of the baffle member. At the same time, it also reduces the safety hazards caused by loose structure or gaps, and improves the safety of passengers during use.

[0019] Optionally, a first positioning groove is formed in the baffle member, and a second positioning groove is formed in the edge sealing member. The first positioning groove communicates with the second positioning groove. The first positioning groove and the second positioning groove are used for placing the connecting member. A closing member is slidably connected to the groove wall of the first positioning groove. A pressing mechanism is arranged at the top of the closing member. The pressing mechanism presses on the closing member through the pushing member, so that the closing member tightly abuts against the connecting member.

[0020] By adopting the above technical solution, when it is necessary to lower the baffle member, the closing member slides in the first positioning groove. Through the control of the pressing mechanism, the closing member moves to a specified position to realize the closing of the hidden groove. At the same time, the connecting member is pressed tightly, reducing the possibility of the handrail shaking during use and improving safety and stability.

[0021] Optionally, a folding member is connected to the top wall of the second positioning groove. One end of the folding member is connected with a pressing plate. The pressing plate is slidably connected with the closing member. The pressing plate is connected with a guide rod. The end of the guide rod away from the pressing plate is slidably connected with the top wall of the second positioning groove.

[0022] By adopting the above technical solution, when the closing member presses on the connecting member, the pressing plate presses on the connecting member together with the closing member. The pressing plate pulls the folding member to unfold, so as to close the second positioning groove, further improving the closing tightness of the hidden opening and thus improving the use safety of the handrail.

[0023] Optionally, the pushing member is located at the top of the locking mechanism, and one end of the pushing member close to the output end of the locking mechanism is inclined.

[0024] By adopting the above technical solution, the locking mechanism stably and quickly pushes the pushing member, optimizes the force transmission path, ensures the efficient and accurate transmission of force, reduces the loss of force, and improves the smoothness and response speed of the operation of the locking mechanism.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the handrail is not in use, the handrail is stored in the hidden groove of the elevator frame, the baffle piece closes the hidden groove and is fixed by the locking mechanism to keep the interior of the elevator tidy and maximize the space; when the handrail needs to be used, the rope member is unwound by operating the rope winding mechanism, driving the baffle piece to open the hidden groove, starting the rotating drive member, and the rotating drive member drives the rotation of the connecting member to smoothly unfold the handrail from the hidden groove to the use position. After use, the rotating drive member and the rope winding mechanism are reversely operated to retract the handrail into the hidden groove, and the baffle piece is closed and locked to restore the tidy state of the interior of the elevator. The hidden design saves space when not in use, makes the interior of the elevator look more spacious, improves the aesthetics and space utilization of the elevator, and improves the comfort and safety of passengers' riding experience; 2. Improve the stability of the handrail during the unfolding and folding process.

[0033] The following is further described in detail in conjunction with the attached Figures 1-6 This application is further described in detail.

[0034] The embodiment of this application discloses a hidden handrail for a car elevator.

[0035] Embodiment 1 Refer to Figure 1 And Figure 2, A concealed handrail for a car elevator, comprising an elevator frame 1, a baffle member 2, a rope winding mechanism 3, a locking mechanism 4 and a mounting seat 5. Passengers ride inside the elevator frame 1. A concealed groove 11 is provided on the inner wall of the elevator frame 1 adjacent to one side near the elevator entrance. The elevator frame 1 is fixedly connected with a mounting plate 12, and the mounting plate 12 is located at the top of the concealed opening. The mounting plate 12 is hinged to the top of the baffle member 2 through a hinge, and the hinge is located at one end of the mounting plate 12 away from the elevator frame 1. The baffle member 2 is used to open or close the concealed groove 11. When the baffle member 2 closes the concealed groove 11, the baffle member 2 fits against the outer wall of the elevator frame 1. A fixing block 21 is fixedly connected to the side of the baffle member 2 away from the elevator frame 1, and a rope member 34 is fixedly connected to one end of the fixing block 21 away from the baffle member 2. In this example, the rope member 34 is fixed to the fixing block 21 by tying a knot. The rope winding mechanism 3 is located at the top of the concealed opening, and the rope winding mechanism 3 is fixedly connected to the end of the rope member 34 away from the baffle member 2, and is used to wind or unwind the rope member 34, so as to open or close the concealed groove 11. The locking mechanism 4 is located at the bottom of the baffle member 2 and is used to lock the closed state of the concealed groove 11. The mounting seat 5 is fixedly connected to the side of the elevator frame 1 close to the mounting plate 12. A rotating driving member 51 is fixedly connected to the top wall of the mounting seat 5. The mounting seat 5 is rotatably connected with a connecting member 52, and the output end of the rotating driving member 51 is connected to one end of the connecting member 52. The rotating driving member 51 drives the connecting member 52 to rotate. One end of the connecting member 52 away from the rotating driving member 51 is fixedly connected with a handrail rod 53. In this example, the rotating driving member 51 adopts an electric motor, and the rope member 34 adopts a fiber rope, so that the rope member 34 has corrosion resistance and anti-aging properties, thereby reducing the possibility of the rope member 34 breaking.

[0036] When the handrail rod 53 is not in use, the handrail rod 53 is stored in the concealed groove 11 of the elevator frame 1. The baffle member 2 closes the concealed groove 11 and is fixed by the locking mechanism 4 to keep the interior of the elevator clean and maximize the space. When the handrail rod 53 needs to be used, start the rope winding mechanism 3 to unwind the rope member 34, drive the baffle member 2 to open the concealed groove 11, start the rotating driving member 51, and the rotating driving member 51 drives the connecting member 52 to rotate, so that the handrail rod 53 is smoothly unfolded from the concealed groove 11 to the use position. After use, operate the rotating driving member 51 and the rope winding mechanism 3 in reverse to retract the handrail rod 53 into the concealed groove 11. The baffle member 2 closes and locks to restore the clean state of the elevator interior, realizing the concealed design of the handrail rod 53, saving space when not in use, making the elevator interior look more spacious, improving the aesthetics and space utilization rate of the elevator, and enhancing the comfort and safety of the passengers' riding experience.

[0037] To improve the safety of using the handrail 53, when in use, the connecting piece 52 is placed on the bottom wall of the hidden groove 11, and the bottom wall of the hidden groove 11 supports the connecting piece 52, thereby improving the stability of using the handrail 53 and reducing the possibility of the handrail 53 shaking.

[0038] The connecting piece 52 and the rotation driving piece 51 are symmetrically arranged at both ends of the handrail 53, providing a stable rotational force for the rotation of the handrail 53.

[0039] The rope winding mechanism 3 includes a rope winding frame 31, a rope winding cylinder 32, and a rope winding driving piece 33. The rope winding frame 31 is located at the top of the mounting plate 12. One end of the rope winding frame 31 is fixedly connected to the outer wall of the elevator frame 1. The rope winding cylinder 32 is rotatably connected to the end of the rope winding frame 31 away from the elevator frame 1. The rope winding driving piece 33 is fixedly connected to the end of the rope winding frame 31 away from the elevator frame 1. The output end of the rope winding driving piece 33 is fixedly connected to one end of the rope winding cylinder 32. The rope winding driving piece 33 is used to drive the rope winding cylinder 32 to rotate. The end of the rope member 34 away from the fixed block 21 is fixedly connected to the rope winding cylinder 32, and the rope member 34 is wound around the outer wall of the rope winding cylinder 32. In this embodiment, the rope winding driving piece 33 is a motor.

[0040] When the baffle 2 needs to be opened, start the rope winding driving piece 33. The output end of the rope winding driving piece 33 drives the rope winding cylinder 32 to rotate. When the rope winding cylinder 32 rotates, the rope member 34 is wound around the rope winding cylinder 32, shortening the distance between the rope winding cylinder 32 and the fixed block 21. The baffle 2 rotates around the top hinge point to open the hidden groove 11. As the rope member 34 continues to be wound, the baffle 2 is completely opened and the hidden groove 11 is exposed, providing sufficient space for the deployment of the handrail 53. When the baffle 2 needs to be closed, operate the rope winding driving piece 33 in reverse. The rope winding cylinder 32 rotates in the reverse direction, and the rope winding cylinder 32 releases the rope member 34, driving the baffle 2 to close the hidden groove 11. By precisely controlling the rotation of the rope winding cylinder 32 by the rope winding driving piece 33, it is ensured that the process of winding and unwinding the rope member 34 is smooth, improving the stability of the opening and closing of the baffle 2 and the user experience of passengers.

[0041] The locking mechanism 4 includes a locking driving piece 41 and a locking piece 42. The locking driving piece 41 is fixedly connected to the side of the elevator frame 1 close to the mounting plate 12. The locking driving piece 41 is located at the bottom of the hidden opening. The output end of the locking driving piece 41 is fixedly connected to the locking piece 42. The locking piece 42 abuts against the baffle 2 through driving, fixing the baffle 2 at the hidden groove 11. In this example, the locking driving piece 41 is a cylinder.

[0042] When it is necessary to close the hidden slot 11, the locking driving member 41 is activated. The locking driving member 41 drives the locking member 42 to move. The locking member 42 contacts the baffle member 2 until the baffle member 2 is completely closed and fits at the hidden slot 11. The hidden slot 11 is completely enclosed. At this time, the baffle member 2 is clamped between the locking member 42 and the elevator frame 1 in a clamping state. When it is necessary to open the hidden slot 11, the locking driving member 41 is operated in the reverse direction to disengage the locking member 42 from the baffle member 2 and release the locking state. The baffle member 2 is opened. By precisely controlling the movement of the locking member 42 through the locking driving member 41, the stability and safety of the baffle member 2 in the closed state are improved, and the risk of accidental opening of the hidden slot 11 in the non-use state is reduced.

[0043] The implementation principle of Embodiment 1 of the present application is as follows: When it is necessary to use the handrail 53, the locking driving member 41 is activated. The locking driving member 41 drives the locking member 42 away from the baffle member 2 to make the baffle member 2 in a free state. The rope winding driving member 33 is activated. The rope winding driving member 33 drives the rope winding cylinder 32 to rotate, thereby winding the rope member 34, making the baffle member 2 rotate around the top hinge to open the hidden slot 11. The rotation driving member 51 is activated. The rotation driving member 51 drives the connecting member 52 to rotate, thereby rotating the handrail 53 into the elevator frame 1 for passengers to use. The connecting member 52 is arranged on the bottom wall of the hidden slot 11 to support the handrail 53 and improve the stability of the handrail 53. When it is not necessary to use the handrail 53, the rotation driving member 51 is activated. The rotation driving member 51 drives the handrail 53 to rotate to the outside of the elevator frame 1. The rope winding driving member 33 is activated. The rope winding driving member 33 drives the baffle member 2 to cover the hidden slot 11 to close the hidden slot 11. The locking driving member 41 is activated. The locking driving member 41 drives the locking member 42 to fix the baffle member 2, making the baffle member 2 clamped between the locking member 42 and the elevator frame 1, thereby realizing the hidden design of the handrail 53, saving space when not in use, making the interior of the elevator look more spacious, improving the aesthetics and space utilization rate of the elevator, and enhancing the comfort and safety of the passengers' riding experience.

[0044] Embodiment 2 The difference in Embodiment 1 is that the connecting member 52 includes a square rod portion 521 and a round rod portion 522. The extended cross-section of the square rod portion 521 is rectangular, and the extended cross-section of the round rod portion 522 is circular. The length direction of the square rod portion 521 is consistent with the length direction of the round rod portion 522. One end of the square rod portion 521 is fixedly connected to one end of the round rod portion 522. The end of the square rod portion 521 away from the round rod portion 522 is fixedly connected to the output end of the rotation driving member 51. The rotation axis direction of the output end of the rotation driving member 51 is parallel to the length direction of the handrail 53. The length direction of the round rod portion 522 is perpendicular to the length direction of the handrail 53. When the handrail 53 rotates into the interior of the elevator frame 1 through the rotation driving member 51, the outer wall of the square rod portion 521 abuts against the bottom wall of the hidden groove 11, increasing the contact area between the connecting member 52 and the hidden groove 11, and further improving the use stability of the handrail 53.

[0045] The implementation principle of Embodiment 2 of this application is as follows: When using the handrail 53, the rotation driving member 51 drives the square rod portion 521 to rotate. The square rod portion 521 is connected to the round rod portion 522, thereby driving the round rod portion 522 to rotate, and then driving the handrail 53 to rotate from the outside of the elevator frame 1 to the inside of the elevator frame 1. The outer wall of the square rod portion 521 abuts against the bottom wall of the hidden groove 11, increasing the contact area between the connecting member 52 and the hidden groove 11, and further improving the use stability of the handrail 53.

[0046] Embodiment 3 Refer to Figure 3 and Figure 4, which is different from Example 2, is that the baffle member 2 is slidably connected with a pushing member 22, and the pushing member 22 slides on the baffle member 2 through a locking member 42. When the locking driving member 41 drives the locking member 42 to move, the locking member 42 pushes the pushing member 22 to slide. One end of the pushing member 22 is fixedly connected with an edge sealing member 6, and the edge sealing member 6 is slidably connected to the top of the baffle member 2. An edge sealing groove is provided on the side of the baffle member 2 away from the fixed block 21. The edge sealing member 6 is located in the edge sealing groove, and the peripheral wall of the edge sealing member 6 is attached to the peripheral wall of the hidden groove 11. An edge sealing spring 61 is fixedly connected to the side of the edge sealing member 6 close to the pushing member 22, and one end of the edge sealing spring 61 away from the edge sealing member 6 is fixedly connected to the side of the edge sealing groove away from the notch. When the edge sealing spring 61 is in a free state The side of the edge sealing member 6 away from the edge sealing spring 61 and the side of the baffle member 2 away from the fixed block 21 are located on the same plane. When the hidden groove 11 is closed, the locking drive member 41 drives the locking member 42 to push the pushing member 22 to slide, and the pushing member 22 pushes the edge sealing member 6. The edge sealing spring 61 extends to make the edge sealing member 6 embedded in the hidden groove 11. The edge sealing member 6 fits with the groove wall of the hidden groove 11, thereby improving the sealing performance of the hidden groove 11 and reducing the possibility of dust and foreign matter entering, thereby improving the cleanliness and aesthetics of the interior of the elevator, and reducing the possibility of passengers' fingers or other body parts being caught in the gap and causing injuries during the opening and closing process of the baffle member 2. At the same time, it also reduces the safety hazards caused by structural looseness or gaps, thereby improving the safety of passengers during use.

[0047] The pushing member 22 is located at the top of the locking member 42, and the end of the pushing member 22 close to the output end of the locking drive member 41 is inclined. Specifically, the inclined portion of the bottom of the pushing member 22 is an inclined plane, and the bottom of the inclined plane is inclined toward the direction close to the baffle member 2. When the locking member 42 pushes the pushing member 22, the inclined surface of the pushing member 22 guides it, thereby improving the pushing smoothness of the pushing member 22.

[0048] One side of the baffle member 2 close to the fixed block 21 is penetrated and provided with a first positioning groove. The first positioning groove is located at the bottom of the baffle member 2 and penetrates through the bottom wall of the baffle member 2. One side of the edge sealing member 6 close to the pushing member 22 is penetrated and provided with a second positioning groove. The second positioning groove is located at the bottom of the edge sealing member 6 and penetrates through the bottom wall of the edge sealing member 6. The first positioning groove and the second positioning groove at the same direction end are communicated with each other. The first positioning groove and the second positioning groove are used for placing the connecting member 52. A closing member 62 is slidably connected to the groove wall of the first positioning groove. A pressing mechanism is arranged at the top of the closing member 62. The pressing mechanism presses on the closing member 62 through the pushing member 22, so that the closing member 62 abuts tightly against the square rod portion 521. A folding member 63 is fixedly connected to the top wall of the second positioning groove. One end of the folding member 63 away from the edge sealing member 6 is fixedly connected to a pressing plate 64. The pressing plate 64 and the closing member 62 are slidably connected through a dovetail groove. The sliding direction of the pressing plate 64 is perpendicular to the sliding direction of the closing member 62. A guiding rod 65 is fixedly connected to the top wall of the pressing plate 64. The guiding direction of the guiding rod 65 is parallel to the sliding direction of the closing member 62. One end of the guiding rod 65 away from the pressing plate 64 is slidably connected to the top wall of the second positioning groove. Thus, when the square rod portion 521 is inserted into the first positioning groove and the second positioning groove, the pressing mechanism presses on the closing member 62, so that both the closing member 62 and the pressing plate 64 press on the square rod portion 521, further improving the use stability of the handrail rod 53.

[0049] Referring to Figure 5 and Figure 6 As shown in, the pressing mechanism includes a sliding member 221, a lifting member 66, a sliding rod 67, a rotating block 68 and a pressing spring 69. The sliding member 221 is fixedly connected to the outer wall of the pushing member 22. An arc-shaped groove 661 in a threaded shape is formed on the outer wall of the lifting member 66. One end of the sliding member 221 away from the pushing member 22 is inserted into the arc-shaped groove 661. The outer wall of the lifting member 66 is annular. The baffle member 2 is provided with a lifting groove matching the lifting member 66. The outer wall of the lifting member 66 is attached to the outer wall of the lifting groove. Thus, the lifting member 66 is spirally lowered or raised through the arc-shaped groove 661. The sliding direction of the pushing member 22 is perpendicular to the lifting direction of the lifting member 66. A sliding strip 671 is fixedly connected to the outer wall of the sliding rod 67. The sliding rod 67 is slidably connected to the lifting member 66 through the sliding strip 671. The sliding direction of the sliding rod 67 is parallel to the lifting direction of the lifting member 66. One end of the sliding rod 67 away from the lifting member 66 is fixedly connected to the top wall of the rotating block 68. One end of the rotating block 68 away from the sliding rod 67 is rotatably connected to the closing member 62. One end of the pressing spring 69 is fixedly connected to the bottom wall of the lifting member 66. One end of the pressing spring 69 away from the lifting member 66 is fixedly connected to the top wall of the rotating block 68.

[0050] Specifically, when the square rod portion 521 is withdrawn from the first positioning groove and the second positioning groove, the sliding rod 67 slides to the top of the arc groove 661 under the action of the pushing member 22, and the closing member 62 presses against the bottom wall of the hidden groove 11.

[0051] The implementation principle of Embodiment 3 of this application is as follows: When the square rod portion 521 abuts against the bottom wall of the hidden groove 11, the rope winding driving member 33 is started to cover the baffle member 2 on the hidden opening. The square rod portion 521 is inserted into the first positioning groove and the second positioning groove. The locking driving member 41 is started, and the locking driving member 41 drives the locking member 42 to move, so that the baffle member 2 is clamped and fixed between the locking member 42 and the elevator frame 1. The locking driving member 41 is continuously driven to make the locking member 42 push the pushing member 22 to slide. The pushing member 22 pushes the edge sealing member 6 into the hidden groove 11, so that the peripheral wall of the edge sealing member 6 fits with the peripheral wall of the hidden groove 11, improving the sealing performance of the hidden groove 11 and reducing the possibility of dust and foreign objects entering. At the same time, the pushing member 22 drives the sliding member 221 to slide, and the sliding member 221 drives the lifting member 66 to descend through the arc groove 661. The descending of the lifting member 66 drives the closing member 62 to descend, compressing the pressing spring 69, so that the closing member 62 presses against the square rod portion 521. At the same time, the folding member 63 is driven to unfold, and the pressing plate 64 presses against the square rod portion 521, so that the hidden groove 11 is sealed under the action of the folding member 63, improving the use safety of the handrail 53 and reducing the possibility of dust or garbage entering the outer wall of the elevator frame 1 and being difficult to clean.

[0052] Embodiment 4 Referring to Figure 5 and Figure 6 In this embodiment, different from Embodiment 3, the square rod portion 521 includes a first square rod 5211, a buffer piece 5212, and a second square rod 5213. The output end of the rotation driving member 51 is fixedly connected to one end of the first square rod 5211. One end of the first square rod 5211 away from the rotation driving member 51 is fixedly connected to one side of the buffer piece 5212. The side of the buffer piece 5212 away from the first square rod 5211 is fixedly connected to the second square rod 5213. The outer walls of the first square rod 5211, the buffer piece 5212, and the second square rod 5213 are smoothly transitioned. One end of the second square rod 5213 away from the buffer piece 5212 is fixedly connected to the round rod portion 522. In this embodiment, the buffer piece 5212 is made of a rubber sheet.

[0053] The implementation principle of Embodiment 4 of this application is as follows: When two rotation driving members 51 drive the armrest rod 53 to rotate, the buffer piece 5212 buffers the rotation of the round rod portion 522, reducing the possibility of damage caused by inconsistent rotation of the two rotation driving members 51. The first square rod 5211, the buffer piece 5212, and the second square rod 5213 all rotate to abut against the bottom wall of the hidden groove 11, and the pressing plate 64 presses the first square rod 5211, the buffer piece 5212, and the second square rod 5213, thereby reducing the possibility of the armrest rod 53 shaking.

[0054] The above are all preferred embodiments of this application. This embodiment is only an explanation of this application and does not limit the protection scope of this application in turn. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
