[0025] Example:

[0026] like Figures 1-7 As shown, an elevator car front wall structure with an integrated light curtain control box includes a left front wall 1 and a right front wall 2. The control box 3 is provided on the inner side of the left front wall 1, and a light curtain bracket 4 is provided on one side of the control box 3. An open space 41 is formed between the light curtain bracket 4 and the control box 3. A first light curtain 51 located in the open space 41 is provided on the light curtain bracket 4, and a second light curtain 52 that works in cooperation with the first light curtain 51 is provided on one side of the right front wall 2.

[0027] This utility model adjusts the installation position of the light curtain device and adopts a modular installation design. The first light curtain 51 is hidden in the open space 41 between the light curtain bracket 4 and the control box 3 through the light curtain bracket 4. This is convenient for installation and prevents direct exposure, thus preventing passengers from accidentally touching it and causing safety risks, thereby improving reliability and feasibility. The second light curtain 52 is installed on the right front wall 2 of the car. The positioning and installation are quick, the operation is convenient, and it saves time and effort.

[0028] The control box 3 includes an operating body 31. The operating body 31 is surrounded by a base plate 32 and a panel 33. A light curtain support 4 is located on the side of the base plate 32. An open space 41 is located between the light curtain support 4 and the panel 33. The open space 41 has an opening 34 on only one side, facilitating the operation of the second light curtain 52 while protecting it from accidental damage.

[0029] The light curtain bracket 4 is L-shaped, and the side of the base plate 32 has several first mounting holes. One side of the light curtain bracket 4 is connected to the first mounting holes of the base plate 32 by connecting bolts 42, and the other side of the light curtain bracket 4 has second mounting holes. The first light curtain 51 is connected to the second mounting holes of the light curtain bracket 4 by pressing bolts 43 and is installed in the open space 41. The first light curtain 51 is quickly installed on the light curtain bracket 4 by pressing bolts 43, and the light curtain bracket 4 is quickly positioned and installed on the control box 3 by connecting bolts 42, making installation convenient.

[0030] The panel 33 is provided with an opening 34 for the rivet bolt 43 to pass through, which can prevent the rivet bolt 43 from scraping when the panel 33 of the control box 3 is opened and closed. This ensures that the first light curtain 51 is installed firmly, has a compact structure and occupies little space, and does not affect the opening and closing operation of the panel 33 of the control box 3 during maintenance. This greatly improves the installation efficiency and maintenance convenience of the elevator.

[0031] The right front wall 2 has an outwardly extending bending frame 21 on its side. The outer surface of the bending frame 21 has a third mounting hole. The second light curtain 52 is connected to the third mounting hole of the bending frame 21 via mounting bolts 22. The bending frame 21 facilitates adjustment of the position of the second light curtain 52 to align it with the first light curtain 51 for better coordination. The first, second, and third mounting holes have been calibrated before leaving the factory to ensure the installation accuracy and requirements of the light curtain device, thus saving on-site installation positioning and debugging time, saving both time and effort.

[0032] A lintel 6 is provided above the left front wall 1 and the right front wall 2, and a cable pre-drilling hole 61 is provided on the lintel 6. The cables of the first light curtain 51 and the second light curtain 52 pass through the cable pre-drilling hole 61 on the lintel 6 and are connected to the car top inspection box, avoiding the cables being exposed, which is both aesthetically pleasing and reliable and safe.

[0033] Working principle: When there is no car door, the first light curtain 51 is installed in the open space 41 on the side wall of the control box 3 through the light curtain bracket 4, and the second light curtain 52 is installed on the right front wall 2. This can prevent the elevator from running when the hall door is open or when passengers are entering the car, thereby protecting the passengers.

[0034] Both the light curtain bracket 4 and the control box 3 are equipped with dedicated first and second mounting holes, used for connecting bolts 42 and rivet bolts 43 respectively, ensuring the stability of the first light curtain 51 installation structure. Furthermore, the connecting bolts 42 and rivet bolts 43 are not directly exposed, which not only improves aesthetics but also makes full use of the space around the control box 3 and allows for some adjustment. Moreover, the connection between the control box 3 and the light curtain bracket 4 can be completed before leaving the factory, greatly facilitating subsequent on-site installation.

[0035] To install the first light curtain 51, first open the panel 33 of the control box 3, align the holes of the first light curtain 51 with the rivet bolts 43 on the light curtain bracket 4, gently push it in and tighten the nuts, then close the panel 33 of the control box 3. To install the second light curtain 52, first align the holes of the second light curtain 52 with the third mounting holes of the bending frame 21 on the right front wall 2, and then install and tighten it using the mounting bolts 22 on the bending frame 21. The entire installation process can be carried out inside the car, ensuring the safety of the installers. The replacement and maintenance of the first light curtain 51 and the second light curtain 52 are also very convenient in the future.

[0036] The parts of this utility model not described in detail are existing technologies and therefore will not be specifically described here.
