[0029] It needs to be further explained that:

[0030] The light curtain power supply box 301 in the light curtain fixing mechanism 3 is firmly fixed on one side of the first car door panel 1 through the bolt 309, which builds a stable foundation platform for the whole mechanism, at the same time, the base 302 fixed on one side not only provides installation support for other components, but also further enhances the stability and firmness of the whole through the screw fixing seat 303 fixed and connected at the top and bottom, in addition, the infrared signal output box 4 and the infrared signal receiving box 5 are fixed on one side of the base 302 through the fastening band 311, so that these key components can be closely connected to form a complete light curtain system, ensuring normal transmission and reception of signals.

[0031] The adjusting seat 306 plays a key role in position adjustment in the whole mechanism, it can smoothly move in the inverted T-shaped sliding groove 304 through the T-shaped sliding block connected in the sliding groove 304, and the left and right symmetrical gear racks 305 are meshed with the circular gear block 308, when the bolt 309 rotates in the threaded hole 307, it can drive the circular gear block 308 to rotate, and then realize the precise adjustment of the position of the adjusting seat 306 on the base 302, this design makes the position of the infrared signal output box 4 can be flexibly changed according to actual needs, to adapt to different elevator car structures and use scenarios, greatly improving the applicability of the light curtain fixing device.

[0032] The positioning plate 310 is fixed on the left and right sides of the adjusting seat 306, the fastening band 311 on one side has elasticity and ductility, and the clamping plate 312 and the limiting plate 313 jointly form a clamping groove on the other side, when the fastening band 311 is wrapped around the components, the clamping block 314 is clamped into the clamping groove, and the components are tightly fixed in the corresponding position by using the characteristics of the fastening band 311, which not only ensures that the infrared signal output box 4 and the infrared signal receiving box 5 will not displace during the working process, ensuring the stable operation of the light curtain system, but also improves the work efficiency in the installation process.

[0033] The working principle of the above embodiment is:

[0034] First, the light curtain power box 301 is stably installed on the side of the first car door panel 1 by the bolt 309, as the power core of the entire light curtain fixing device, which introduces the external power supply into the system, provides necessary power support for subsequent signal output and reception, and ensures that each part of the equipment can operate normally.

[0035] Secondly, the infrared signal output box 4 is fixed on the side of the base 302 of the light curtain fixing mechanism 3, powered by the light curtain power box 301, which continuously emits infrared signals arranged in a certain rule and mode, forming a light curtain area covering the space where the elevator car door is opened, providing a signal source for detecting whether there is an object blocking.

[0036] Then, under the condition that the elevator car door is opened, the infrared signals emitted by the infrared signal output box 4 propagate straight in space, forming an invisible light curtain, and each infrared signal of the light curtain corresponds to the infrared signal receiving box 5 on the other side. Under normal circumstances, the signal can be transmitted stably.

[0037] Next, the infrared signal receiving box 5 is also fixed on the side of the base 302, corresponding to the infrared signal output box 4, which is responsible for receiving the infrared signals emitted from the infrared signal output box 4. Once an object enters the light curtain area and blocks the transmission of infrared signals, the signals received by the infrared signal receiving box 5 will change.

[0038] Finally, when the infrared signal receiving box 5 detects an abnormal signal, i.e. the infrared signal is blocked, it will immediately feed back the signal to the elevator control system. After receiving the abnormal signal, the elevator control system will quickly respond and immediately stop the closing action of the elevator door, and then reopen the elevator door to avoid the situation of pinching people or objects, and ensure the safety of the passengers.

[0039] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
