Specific embodiments

[0023] The following combines the accompanying drawings and embodiments to further describe the specific embodiments of the present invention. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention.

[0024] "Top surface", "bottom", and "bottom surface" are referenced based on the normal use state of the flat layer sensor, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present invention.

[0025] As Figures 1-3 shown, a flat layer sensor for an elevator includes the main body 2 of the flat layer sensor. The main body 2 is detachably connected to a mounting bracket 1. A protection plate 3 is provided directly above the main body 2. The orthographic projection of the main body 2 on the protection plate 3 falls within the range of the protection plate 3. The side of the protection plate 3 is rotatably connected to the mounting bracket 1. A buffer mechanism 4 is also provided between the protection plate 3 and the mounting bracket 1.

[0026] When the above elevator leveling sensor is in use, holes for passing bolts are provided on the mounting bracket 1, and the mounting bracket 1 can be fixed to the elevator car through bolts. A partition is installed in the elevator shaft, and the main body 2 is fixed to the mounting bracket 1 through bolts and nuts, facilitating the installation of the main body 2. When the elevator car runs to the position where the partition is located, the leveling sensor will receive the signal generated by the partition (such as magnetic field change or optical path change), thus triggering the parking action of the elevator; existing leveling sensors are usually of U-shaped structure, so a notch needs to be set at the position corresponding to the U-shaped opening of the protective plate 3 to facilitate the passage of the partition. The protective plate 3 installed on the mounting bracket 1 shields directly above the main body 2. When an object falls from a height, the protective plate 3 can block the falling object, preventing the falling object from directly hitting the main body 2, reducing the probability of damage to the leveling sensor, and thus enhancing the stability and safety of elevator operation; the setting of the buffer mechanism 4 can absorb part of the impact force received by the protective plate 3, reducing the probability of damage to the protective plate 3 and prolonging the overall service life of the equipment; the protective plate 3 is rotatably connected to the mounting bracket 1. When there is a pile of objects on the top surface of the protective plate 3, one end of the protective plate 3 can tilt downward under the action of the gravity of the objects, causing the objects to slide off, reducing the accumulation of falling objects on the protective plate 3, alleviating the wear of the protective plate, and prolonging its service life.

[0027] A further improvement is that, as Figure 2 shown, a connecting shaft 304 is provided on the side of the protective plate 3. The connecting shaft 304 is connected to the mounting bracket 1 through a bearing. The protective plate 3 includes a top plate 301 and a bottom plate 303, and a buffer layer 302 is provided between the top plate 301 and the bottom plate 303. The connecting shaft 304 is connected to the mounting bracket 1 through a bearing, enabling the protective plate 3 to rotate around the connecting shaft, so that the buffer mechanism 4 can effectively buffer the protective plate 3; the buffer layer 302 is a polyurethane foam layer, and the top plate 301 and the bottom plate 303 are stainless steel plates. The top plate 301 and the bottom plate 303 can protect the buffer layer 302, enhancing the overall strength of the protective plate 3. The setting of the buffer layer 302 enables the protective plate 3 to have better buffering performance, reducing the probability of damage when it is impacted. At the same time, the setting of the buffer layer 302 can also achieve a better noise reduction effect.

[0028] A further improvement is that, as Figure 4 and 5As shown, both the top plate 301 and the bottom plate 303 are corrugated plates, and there is an included angle between the corrugation distribution directions of the top plate 301 and the bottom plate 303. The corrugated plate has good buffering performance and has a better anti-bending effect than a flat plate along the extension direction of its own corrugations. In this way, the buffering performance and strength of the top plate 301 and the bottom plate 303 can be improved, thereby enhancing the anti-impact effect of the protection plate 3 and extending the service life of the protection plate 3; the corrugation extension directions of the top plate 301 and the bottom plate 303 are arranged at a 90-degree included angle, so that the protection plate 3 has good anti-bending performance in both the length and width directions, thereby enhancing the overall strength of the protection plate 3.

[0029] A further improvement is that, as Figures 1-3 shown, the buffer mechanism 4 includes a guide post 401 vertically arranged on the mounting bracket 1. The guide post 401 is slidably fitted with a first guide sleeve 402. A spring 403 with both ends connected to the guide post 401 and the first guide sleeve 402 is sleeved on the guide post 401. The first guide sleeve 402 is hinged to the protection plate 3 through a transmission rod 404. When the protection plate 3 is impacted, the protection plate 3 rotates downward around the connecting shaft 304. Under the transmission action of the transmission rod 404, the impact force received by the protection plate 3 is transferred to the first guide sleeve 402, so that the first guide sleeve 402 moves downward and compresses the spring 403. Part of the impact force is absorbed by the compression of the spring 403, thereby realizing the buffering effect on the protection plate 3, enhancing the anti-impact performance of the protection plate 3, further enhancing the protection effect on the flat layer inductor, and reducing its failure rate.

[0030] A further improvement is that, as Figure 5 shown, a support bar 305 is arranged on the bottom surface of the bottom plate 303. One end of the transmission rod 404 is hinged to the first guide sleeve 402, and the other end of the transmission rod 404 is hinged to the support bar 305. The support bar 305 is attached to the bottom surface of the bottom plate 303, which can play a stable supporting effect on the whole protection plate 3, thereby enhancing the overall strength of the protection plate 3 and enhancing the transmission stability between the protection plate 3 and the transmission rod 404.

[0031] A further improvement is that, as Figure 1 and 2As shown in the figure, a limiting mechanism is further provided between the protection plate 3 and the mounting bracket 1; the limiting mechanism includes a second guide sleeve 406 that is slidably engaged with the guide post 401. The second guide sleeve 406 is hinged to the support bar 305 through a support rod 407. A positioning block 405 fixedly connected to the mounting bracket 1 is provided below the second guide sleeve 406. The setting of the positioning block 405 can limit the moving distance of the second guide sleeve 406. Under the connection action of the support rod 407, it is used to limit the rotation angle of the protection plate 3, thereby preventing the probability of collision between the protection plate 3 and the main body 2, and reducing the probability of damage to the main body 2; by simultaneously supporting the protection plate 3 through the transmission rod 404 and the support rod 407, the stability of the protection plate 3 can be improved, and the transmission rod 404 and the support rod 407 can also protect both sides of the main body 2, improving the protection effect on the leveling sensor.

[0032] A further improvement is that, as Figure 3 shown in the figure, the main body 2 is connected to the mounting bracket 1 through a bolt assembly 103, and a buffer washer 102 is provided between the main body 2 and the mounting bracket 1. When the protection plate 3 is impacted, part of the impact force is transmitted to the main body 2 through the mounting bracket 1. Through the setting of the buffer washer 102, a buffering effect can be achieved between the mounting bracket 1 and the main body 2, thereby reducing the impact force received by the main body 2 and reducing the probability of failure of the main body 2.

[0033] A further improvement is that, as Figure 3 shown in the figure, the mounting bracket 1 is further provided with a sealing strip 101, and the sealing strip 101 is slidably and sealingly connected to the connecting shaft 304. The sealing strip 101 is used to fill the gap between the protection plate 3 and the mounting bracket 1. When the falling object from a high place is liquid, it can prevent the liquid from flowing along the gap between the mounting bracket 1 and the protection plate 3 to the main body 2, thereby improving the protection effect on the leveling sensor.
