It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-5 As shown, an anti-collision buffer structure in an elevator includes a car 1, a support mechanism 2 is arranged inside the car 1, the support mechanism 2 includes a handrail 201, a connecting rod 203 is arranged on the surface of the handrail 201, a support plate 204 is arranged on the surface of the connecting rod 203, the surface of the support plate 204 is rotatably connected to a rotating plate 205 through a damping bearing, a cylinder 210 is installed on the surface of the car 1, a connecting plate 206 is arranged on the output end of the cylinder 210, two sliders 207 are symmetrically arranged on the surface of the connecting plate 206, the two sliders 207 are fixedly connected to the handrail 201, a spring 208 is arranged on the surface of the car 1, and a buffer plate 209 is arranged on the surface of the spring 208.

[0025] The effect achieved by the entire embodiment 1 is that when an occupant falls, his body hits the buffer plate 209, and the spring 208 can provide buffering. When the occupant falls on the floor of the car 1, the cylinder 210 drives the connecting plate 206 to move downward, the connecting plate 206 drives the slider 207 to move downward, and the slider 207 drives the handrail 201 to move downward. After moving to a position where the passenger can hold on, the passenger can support himself on the handrail 201, and then the handrail 201 is moved upward to facilitate supporting the passenger and avoid the situation where the passenger falls to the ground and has difficulty standing up. The rotating plate 205 can be rotated so that the rotating plate 205 is horizontally supported on the support plate 204. At this time, the support area can be increased, so that the passenger can stand more easily.

[0026] Embodiment 2, as Figure 1-5 As shown, the buffer plate 209 includes a positioning plate 3 and a rubber pad 4, the surface of the positioning plate 3 is provided with a first Velcro 5, the surface of the rubber pad 4 is provided with a second Velcro 6, the first Velcro 5 is bonded to the second Velcro 6, the surface of the positioning plate 3 is provided with a limiting groove, the surface of the car 1 is provided with a limiting plate 7, the limiting plate 7 is engaged with the limiting groove, the surface of the positioning plate 3 is provided with a positioning groove for fixing the spring 208, the surface of the car 1 is provided with two slide rails 8, the two sliders 207 are slidably connected to the slide rails 8, the surfaces on the opposite sides of the two slide rails 8 are provided with through holes for the connecting plate 206 to pass through, the surfaces of the two slide rails 8 are provided with limiting rods 9, and the two limiting rods 9 are slidably connected to the sliders 207.

[0027] The effect achieved by the entire embodiment 2 is that by setting the first Velcro 5 and the second Velcro 6, the rubber pad 4 can be removed to facilitate cleaning of the rubber pad 4, the set limit plate 7 can support the positioning plate 3, so that the positioning plate 3 is more stable when moving, and the back of the positioning plate 3 is provided with a positioning groove, so that the buffer distance can be increased and the practicality of the device is improved. The set slide rail 8 can protect the slider 207, and a through hole is opened on the slide rail 8 to facilitate the connection plate 206 to pass through and connect the two slide rails 8. The set limit rod 9 can limit the slider 207 to improve the stability of the slider 207 when moving.

[0028] The working principle is that when the passenger falls, the body hits the buffer plate 209, and the buffer plate 209 moves along the limit plate 7. The set spring 208 can provide buffering, and the set rubber pad 4 avoids scratches and has a good buffering effect. At the same time, the rubber pad 4 can be removed. During installation, you only need to fit the second Velcro 6 on the back to the first Velcro 5 on the positioning plate 3. The operation is simple and quick. When the passenger falls on the ground of the car 1, the cylinder 210 drives the connecting plate 206 to move downward, and the connecting plate 206 drives the slider 207 to move downward along the slide rail 8. The slider 207 drives the handrail 201 to move downward. After moving to the position where the passenger can hold on, it is supported, and then the handrail 201 is moved upward, and the rotating plate 205 can be rotated so that the rotating plate 205 is horizontally supported on the support plate 204. At this time, the support area can be increased.

[0029] The wiring diagram of the cylinder 210 in the present invention is common knowledge in the art, and its working principle is a known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the cylinder 210 are not explained in detail.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
