Detailed Description

The technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention.

The utility model discloses a do not have sedan-chair door elevator car protection device can avoid the injury that object or passenger's limbs that do not have sedan-chair door elevator car entry 31 lower part and 50 inner walls of elevator well or room door inner wall direct contact brought, and then protect object or passenger.

As shown in fig. 1, for the protection device of the elevator car without car door disclosed by the present invention, the protection device comprises a flexible sensor 10 and a signal processor 20, wherein the flexible sensor 10 is in communication connection with the signal processor 20. The elevator car 30 includes a car entrance 31, a car platform 32, and a car side wall 33, the car platform 32 is disposed at a lower portion of the car entrance 31, and the car side wall 33 is connected to the car platform 32. The flexible sensor 10 is arranged at the car entrance 31, the flexible sensor 10 is fixed on the car platform 32, and the flexible sensor 10 is positioned between the car platform 32 and the inner wall of the elevator hoistway 50 and used for detecting whether the extrusion force is applied; the signal processor 20 is arranged on the car side wall 33 of the elevator car 30 and used for acquiring the state signal of the flexible sensor 10 and sending the state signal of the flexible sensor 10 to the elevator controller 60, and the elevator controller 60 controls the elevator car 30 to brake through the traction machine 40 and controls the elevator car 30 to run to a position before receiving the effective signal in a low-speed state through controlling the traction machine 40.

Further, the flexible sensor 10 has a certain compression stroke, so that the object or the passenger limb to be pressed has a certain buffer space, and the injury to the object or the passenger limb is reduced. In practice, it is preferred that the surface of the flexible sensor 10 is flush with the surface of the car platform 32, or that the surface of the flexible sensor 10 is lower than the surface of the car platform 32. By adopting the arrangement mode, the flexible sensor 10 can effectively avoid the mistaken extrusion of the object or the limb of the passenger on the flexible sensor 10, and can make up the leak of the light curtain protection system at the entrance 31 of the elevator car without the car door, thereby better protecting the object or the passenger.
