DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0024] like Figure 1-4 As shown, the car platform 100 in one embodiment of the present invention is mainly used in platform elevators and includes a platform assembly and a detection assembly 20. The platform assembly includes a platform base plate 11 and a touch panel 12 supported on the edge of the platform base plate 11. The bottom surface of the touch panel 12 is spaced apart from the platform base plate 11. The detection assembly 20 includes a switch 21, which is fixed to the platform base plate 11 and disposed in the gap between the touch panel 12 and the platform base plate 11. The switch 21 abuts against the bottom surface of the touch panel 12 and is connected to the elevator control system via a wire 28. The switch 21 can be opened or closed when subjected to pressure.

[0025] The touch panel 12 is located at the outermost edge of the entire car bottom platform 100, and there is a certain gap between it and the inner wall of the shaft. During normal operation of the elevator, the touch panel 12 does not squeeze the switch 21, and the switch 21 is in a closed state. During the elevator's upward movement, if a passenger operates the elevator improperly, causing a finger, toe, or other body part or other foreign object to be stuck in the gap between the touch panel 12 and the inner wall of the shaft, the touch panel 12 will be squeezed and displaced relative to the platform bottom plate 11, and the gap between the two will become smaller. The switch 21 will be disconnected after being squeezed by the touch panel 12, resulting in the disconnection of the circuit with the elevator control system and the emergency braking of the elevator to prevent the passenger's body part from being pinched between the car bottom platform 100 and the shaft wall, or foreign objects from entering the gap between the car bottom platform 100 and the shaft wall and causing the elevator to be stuck.

[0026] Preferably, the detection assembly 20 also includes a return spring 22, which is fixed to the edge of the platform base plate 11 and located within the gap. The touch plate 12 is supported by the return spring 22. When relative displacement occurs between the touch plate 12 and the platform base plate 11, the return spring 22 compresses and stores energy. When the touch plate 12 loses its force, the return spring 22 recovers its deformation and releases the stored energy, pushing the touch plate 12 upward. The switch 21 is reconnected, the circuit is completed, and the elevator resumes operation.

[0027] In one embodiment, a guide hole 111 is defined in the platform base plate 11. The detection assembly 20 further includes a stop pin 23 secured to the lower surface of the touch panel 12 and inserted into the guide hole 111. A return spring 22 is sleeved around the stop pin 23. The stop pin 23 restricts the movement of the touch panel 12, limiting it to vertical movement. Furthermore, the return spring 22 is restricted to axial deformation, preventing lateral deformation or even movement in other directions, thereby improving the stability of the return spring.

[0028] Preferably, a rubber washer 24 is fixed within the guide hole 111, into which the stop pin 23 is inserted. This rubber washer 24 serves to enhance the stability of the stop pin 23, limiting its axial movement to none other than the platform floor 11. Furthermore, this rubber washer 24 prevents metal contact between the stop pin 23 and the platform floor 11, thereby reducing elevator noise during operation and enhancing the user experience.

[0029] Furthermore, the detection assembly 20 includes a guide base 25 fixed to the platform base 11. The switch 21 is fixed to the guide base 25, and the return spring 22 is supported on the guide base 25. The guide base 25 has a through hole for the limit pin 23 to pass through. The guide base 25 is used to increase the rigidity of the platform base 11 at this position, preventing bending after long-term use, thereby increasing the service life.

[0030] In one embodiment, a sleeve 26 is fixed in the through hole of the guide seat 25 and extends to both sides to increase the contact area between the guide seat 25 and the limiting pin 23 to prevent the limiting pin 23 from bending or other problems.

[0031] Preferably, a bushing 27 is provided in the sleeve 26, which is squeezed between the inner wall of the sleeve 26 and the limit pin 23, and is also used to stabilize the moving direction of the limit pin 23 and reduce the metal friction between the limit pin 23 and the inner wall 26 of the sleeve, thereby reducing the elevator operation noise and improving the user experience.

[0032] like Figure 2 As shown, the touch panel 12 is a U-shaped plate surrounding the edge of the platform bottom plate 11 (the remaining side is connected to the drive mechanism). At least one set of the above-mentioned detection components 20 is set below each side of the touch panel 12 to increase the detection position and avoid the situation where the touch panel 12 is pressed too far from the detection component 20. The deformation range of the detection component 20 is too small to successfully trigger the switch 21 to disconnect, resulting in the elevator being unable to stop normally. Figure 2 In the embodiment, a group of detection components 20 are respectively provided under the two side plates of the touch panel 12, and two groups of detection components 20 are provided under the middle plate. Of course, the number of detection components 20 can be further increased to improve the detection accuracy, which is not limited in this embodiment.

[0033] In one embodiment, the platform assembly further includes a structural panel 13 supported above the platform base plate 11. Transverse reinforcement ribs 14 are provided on the surface of the platform base plate 11 to enhance the overall rigidity and stability of the platform assembly and improve user experience. The platform assembly also includes two opposing platform forks 15 supported on the platform base plate 11 and connected to the elevator drive mechanism for movement within the elevator shaft. Transverse reinforcement ribs 14 are connected at both ends to the pair of platform forks 15. A detection assembly 20 is disposed outside the platform forks 15.

[0034] Preferably, a decorative base plate 16 is also supported on the structural panel 13, and a trim strip 17 is provided on the side of the decorative base plate 16. One end of the trim strip 17 is supported on the platform base plate 11, and the other end is fixed to the edge of the decorative base plate 16 to cover the burrs and shrinkage gaps on the edge of the decorative base plate 16. The decorative base plate 16 and the trim strip 17 can visually improve the consistency of the platform assembly and enhance its aesthetics.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
