Description

Technical Field

[0001] This utility model relates to the technical field of elevator buttons and related technologies, and in particular to a thin elevator button structure. Background Technology

[0002] While ensuring the quality of elevator buttons, elevator manufacturers continuously improve the structure of elevator buttons from the perspectives of development, manufacturing, and cost. For example, application number CN202022330971.6 discloses a novel modular elevator button structure, comprising three main modules: a button unit, a button frame, and a button cap. The button unit includes a built-in base plate assembly, a light-diffusing plate, a return spring, a button, and a main housing for controlling elevator movement and emitting light; the button cap receives the operator's press and receives and reflects light to indicate the elevator's calling status; the button frame connects the button unit and the button cap, ensuring smooth pressing of the button cap and increasing the light-emitting area. This invention has a simple structure, is easy to install, and allows for the combination of various button modules to create buttons with different functions and styles.

[0003] Utility model patent application number CN202322350096.1 discloses a button structure, including an outer ring, metal lettering, plastic lettering, a movable cover, an outer frame, and a circuit board. The movable cover and circuit board are respectively disposed at both ends of the annular outer frame. A tactile switch is disposed on the side of the circuit board facing the movable cover. Several axial supports are disposed on the inner side of the outer frame, and springs are sleeved on the supports. The springs abut against the movable cover and provide a restoring force to the movable cover after pressing. A through hole corresponding to the tactile switch is disposed in the center of the movable cover. A first groove is disposed on the side of the movable cover facing away from the circuit board, and a second groove is disposed on the first groove. The plastic lettering is embedded in the second groove, and the metal lettering is embedded in the first groove. This utility model has a compact structure, good overall performance, and the spring can reciprocate better when the button is pressed, effectively avoiding button jamming caused by burrs from the injection molding process. It is easy to install and has a long service life.

[0004] Utility model patent application number CN202220286551.9 discloses a snap-on elevator button. Specifically, it discloses a snap-on elevator button including a metal letter plate, a letter plate injection-molded base, a transmission component, a housing, and a PCB circuit board. The metal letter plate is mounted on the letter plate injection-molded base, the letter plate injection-molded base is snapped onto the transmission component, the transmission component is installed inside the housing, and the PCB circuit board is mounted on the bottom surface of the housing and snapped into the transmission component. This utility model elevator button has a compact structure and reasonable layout, relying entirely on a snap-on method for assembly. It uses a plastic spring sheet to store energy and deform to reset the button. The total height of the main body is controlled at 11mm, offering high compatibility and reducing material costs. During manual operation, the corresponding assembly steps are reduced, the error rate is low, manufacturing efficiency is improved, and labor costs are reduced.

[0005] The utility model patent with application number CN202022330971.6 still has room for improvement and optimization in terms of structural design and assembly process. For example, the circuit board is too large, the pre-fixation of the circuit board is inconvenient, the distribution of LED beads on the circuit board needs to be optimized, and the light-diffusing plate, buttons, and pads can be integrated into a single design, which are areas for further optimization. This patent is an optimization and improvement of this utility model patent.

[0006] The utility model patent with application number CN202322350096.1 has a large number of parts and a low degree of integration. The button assembly relies on threads and self-supplying screws, which makes the installation convenient and disassembly unsatisfactory, increasing the production and manufacturing costs.

[0007] The utility model patent with application number CN202220286551.9 has a complex internal component design, and the plastic spring-type return structure reduces the lifespan and reliability of the button. Furthermore, it also suffers from problems such as exposed circuit boards and inconvenient disassembly. Utility Model Content
