Non-contact switches, on the other hand, can avoid this problem. Therefore, there is a need for an elevator door opening and closing sensing component that is easy to install and has a simple structure. Summary of the Invention

[0023] refer to Figures 1 to 6 According to a preferred embodiment of the elevator door opening and closing sensing component of this utility model, it should be noted that the structure of the elevator door opening and closing sensing component is as follows: Figure 3-6 As shown, it is specifically a switch structure, wherein the top of the elevator door opening and closing sensing component is located on the door frame crossbeam 200 of the elevator door, and its bottom is located on the door frame upper beam 100 of the elevator door, and the structure of the door frame crossbeam 200 and the door frame upper beam 100 is as follows. Figure 1 and 2 As shown.

[0024] It is worth mentioning that the elevator door opening and closing sensing component includes a stationary contact assembly 10 and a moving contact assembly 20. The stationary contact assembly 10 is located at the upper beam 100 of the door frame, and the moving contact assembly 20 is located at the crossbeam 200 of the door frame. That is, when the upper beam 100 of the door frame is directly opposite the crossbeam 200 of the door frame, the moving contact assembly 20 contacts the stationary contact assembly 10.

[0025] Specifically, the static contact seat assembly 10 includes a first base 11, which is disposed on the upper beam 100 of the door frame, as shown in the figure below. Figure 1 The recess shown is provided, and one side of the first base 11 has a guide portion 111. The guide portion 111 contacts the upper beam 100 of the door frame. The first base 11 also has two opposing first positioning holes 1101. Two external screws pass through the two first positioning holes 1101 respectively and are fastened in the recess to define the position of the first base 11. It is worth mentioning that the first base 11 also has two spaced-apart first mounting holes 1102, which are located between the two first positioning holes 1101. Specifically, each first mounting hole 1102 is implemented as a stepped hole.

[0026] Furthermore, the bottom of the first base 11 also has a first protrusion 112, through which both first mounting holes 1102 penetrate. The static contact assembly 10 also includes two first inserts 12, each engaging with one of the first mounting holes 1102. Notably, each insert 12 has an insertion portion 121 and abutment portion 122. The insertion portion 121 is connected to the abutment portion 122, and the insertion portion 121 engages with the first mounting hole 1102, while the abutment portion 122 abuts against the stepped surface of the first mounting hole 1102. Additionally, the end of the abutment portion 122 opposite to the insertion portion 121 is flush with or higher than the wall surface of the first base 11 where the first mounting hole 1102 is located.

[0027] It should be noted that each of the insertion portions 121 has a first connecting hole at its bottom, and the outer wall of each insertion portion 121 also has a second connecting hole. The first connecting hole communicates with the second connecting hole, wherein the first connecting hole is perpendicular to the second connecting hole. The outer wall of the first protrusion 112 also has two oppositely arranged third connecting holes, and the two third connecting holes are respectively connected to the two second connecting holes.

[0028] It is worth mentioning that the moving contact assembly 20 also includes a second base 21, which is disposed in the mounting groove of the door frame beam 200. Specifically, the second base 21 has two opposing second positioning holes 2101, and two external screws respectively cooperate with the two second positioning holes 2101 and are fixed in the mounting groove to limit the position of the second base 21.

[0029] Specifically, the second base 21 has a second protrusion 211 on the side opposite to the first base 11. The second protrusion 211 is located in the mounting groove, and the second base 21 also has two spaced second mounting holes 2102. The two second mounting holes 2102 are located between the two second positioning holes 2101, and the two second mounting holes 2102 also penetrate the second protrusion 211.

It is also worth mentioning that the above-mentioned sensing component is implemented as a magnetic switch, that is, the abutment part 122 can be implemented as a magnetic component, and the contact member 23 is a sensing component. That is, the sensing component senses the magnetic component to detect whether the upper beam 100 and the cross beam 200 of the door frame are in the correct position. Another advantage of this application is that it reserves the structure for conversion to a contact switch based on the non-contact design. That is, the guide rod and contact member can be implemented as a contact switch structure. A spring can be added inside the end of the guide rod to ensure the guide rod returns to its original position, and the guide rod is raised by contacting the contact member with the guide part, thereby contacting the sensing component at a predetermined position to detect whether the elevator door is closed.
