[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Please see Figures 1-4 An elevator landing door safety protection device includes an elevator landing door body 100 and a drive component housing 200, wherein the drive component body 300 is assembled inside the drive component housing 200.

[0025] The elevator landing door body 100 is internally equipped with a protective component 400, which includes a storage airbag 401 and a hydraulic chamber 402. The storage airbag 401 stores a non-Newtonian fluid. One end of the hydraulic chamber 402 is slidably connected to a transmission rod 403, which is located on the side of the storage airbag 401 and is fixed to the storage airbag 401. When the center of the side of the elevator landing door body 100 is subjected to a violent impact, the storage airbag 401, which is fixedly connected to the elevator landing door body 100, is also subjected to a violent impact. The non-Newtonian fluid inside the storage airbag 401 hardens rapidly due to the violent impact and vibrates, thereby causing the transmission rod 403, which is fixedly connected to the storage airbag 401, to vibrate. A locking rod 404 is slidably connected to the other end of the hydraulic chamber 402. A spring 405 is fixedly connected to the side of the transmission rod 403. The end of the spring 405 away from the transmission rod 403 is located inside the hydraulic chamber 402 and is fixedly connected to the inner wall of the hydraulic chamber 402. When the transmission rod 403 vibrates, it moves a certain amount in conjunction with the spring 405 fixedly connected to the transmission rod 403. This, in turn, increases the pressure inside the hydraulic chamber 402, which is slidably connected to the transmission rod 403. A protective plate 407 is connected to the inside of the elevator landing door body 100 via a spring 406. A slot 408 is provided on the side of the protective plate 407, and the locking rod 404 is located in the slot 408, with the cross-sectional shape of the locking rod 404 matching that of the slot 408. When the pressure inside the hydraulic chamber 402 increases, it causes the lever 404, which is slidably connected to the hydraulic chamber 402, to move. The lever 404 then moves out of the slot 408 on the protective plate 407, thereby freeing the protective plate 407 from restriction. Under the action of the second spring 406, the protective plate 407 moves, thereby further protecting the elevator landing door body 100 and improving the protective effect of the device in this situation.

[0026] In use, when the center of the side of the elevator landing door body 100 is subjected to a violent impact, the storage airbag 401, which is fixedly connected to the elevator landing door body 100, is also subjected to a violent impact. The non-Newtonian fluid inside the storage airbag 401 hardens rapidly due to the violent impact and generates vibration, thereby causing the transmission rod 403, which is fixedly connected to the storage airbag 401, to vibrate. In conjunction with the spring 405, which is fixedly connected to the transmission rod 403, the transmission rod 403 moves to a certain extent. In conjunction with the hydraulic chamber 402, which is slidably connected to the transmission rod 403, the pressure inside the hydraulic chamber 402 increases, causing the locking rod 404, which is slidably connected to the hydraulic chamber 402, to move. The locking rod 404 then moves out of the slot 408 on the protective plate 407, thereby freeing the protective plate 407 from restriction and allowing it to move under the action of the spring 406, thus further protecting the elevator landing door body 100.

[0027] Example 2

[0028] Please see Figures 1-4 Based on Embodiment 1, an auxiliary component 500 is provided on the protective plate 407. The auxiliary component 500 includes a pressure chamber 501, which is located inside the protective plate 407 and is fixed to the protective plate 407. One end of the pressure chamber 501 is fixedly connected to an elastic airbag 502. When the protective plate 407 moves, causing the elastic airbag 502 to be compressed, the gas stored in the elastic airbag 502 is squeezed into the pressure chamber 501, increasing the pressure inside the pressure chamber 501. The other end of the pressure chamber 501 is slidably connected to a support block 503. When the pressure inside the pressure chamber 501 increases, the support block 503 slidably connected to the pressure chamber 501 can be moved and extended to further support and protect, thereby further improving the protective effect of the device.

[0029] In use, based on Embodiment 1, when the protective plate 407 moves, causing the elastic airbag 502 to be compressed, the gas stored in the elastic airbag 502 is then compressed into the air pressure chamber 501 fixedly connected to it, which increases the pressure in the air pressure chamber 501 and drives the support block 503 slidably connected to the air pressure chamber 501 to move and extend, thereby further supporting and protecting it.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
