Description

Technical Field

[0001] This utility model relates to the field of elevator manufacturing, specifically to an embedded elevator mechanical button. Background Technology

[0002] The basic functions of elevator buttons include floor selection, emergency call, door opening / closing control, overload alarm, fault indication, and accessibility design. As the main carrier of human-machine interaction in elevators and the core interactive component of the elevator system, their functional design directly affects the user experience and elevator safety.

[0003] Existing elevator button lettering uses glue to bond hardware, which is prone to aging and falling off (lifespan is usually <10 million times). The light-transmitting components require a multi-layer stacking of light guide plate + reflector + lettering, which is complicated to assemble and prone to light attenuation. The installation method is simple (only screw fixing) and cannot meet the thickness requirements of modern elevator panels. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide an embedded elevator mechanical button.

[0005] To achieve the purpose of this utility model, the technical solution adopted is as follows:

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, in the following descriptions, well-known structures and technologies have been omitted to avoid unnecessary confusion regarding the concept of this utility model.

[0028] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] like Figure 1 An embedded elevator mechanical button, as shown in Figure 2 or 3, includes a rear housing structure 100, which includes an enclosing housing 101. A rear mounting plate 102 is provided at the rear end of the enclosing housing 101. The lengths of both ends of the rear mounting plate 102 are greater than the length of the enclosing housing 101.

[0030] Mounting holes 1022 can be made on both sides of the rear mounting plate 102 as needed.

[0031] A retaining plate 103 is provided at the rear end of the rear mounting plate 102, so that multiple retaining plates 103 can be engaged with the elevator mounting slot (not shown in the figure) through upper and lower cooperation.

[0032] The rear mounting plate 102 has a mounting window 1021, which is mainly used to connect the internal components to the external circuit through the circuit.

[0033] Limiting mounting posts 104 are provided around the inner perimeter of the mounting window 1021. The circuit board 200 is limited and mounted on the limiting mounting posts 104 by corresponding mounting holes 201 provided around its perimeter.

[0034] The enclosed housing 101 has protruding buckles 1011 around its perimeter, and the buckle plate 300 is installed at the front end of the enclosed housing 101 through the buckle holes 301 corresponding to the protruding buckles 1011.

[0035] In an embodiment of this utility model, for better installation, protruding first to fourth buckles 1011 are provided around the enclosure housing 101, and the buckle plate 300 is installed at the front end of the enclosure housing 101 through first to fourth buckle holes 301 corresponding to the first to fourth buckles 1011.

[0036] A mounting protrusion ring 310 is provided at the front end of the buckle plate 300. The light-transmitting plate 400 is installed at the front end of the buckle plate 300 through a light-transmitting ring 410 that is adapted to the mounting protrusion ring 310. Specifically, the light-transmitting ring 410 is fitted over the outside of the mounting protrusion ring 310.

[0037] A slot 411 is provided around the light-transmitting ring 410, and the lower end of the embedded letter 500 is installed in the slot 411 through the mounting protrusion 501.

[0038] In this embodiment of the invention, for better installation, first to fourth slots 411 are provided at intervals around the light-transmitting ring 410. The lower end of the embedded letter 500 is installed in the first to fourth slots 411 through the corresponding first to fourth mounting protrusions 501. The light-transmitting grooves 412 on the light-transmitting ring 410 can transmit light, allowing the light from the light-emitting components on the circuit board 200 to pass through onto the embedded letter 500.

[0039] A spring (not shown in the figure) is provided between the lower end of the embedded character chip 500 and the rear housing structure 100. The spring provides feedback on the touch action received at the front end of the embedded character chip 500. The spring mainly achieves the "press-rebound" function of the button through elastic deformation and restoring force. The spring is an existing spring structure.

[0040] The overall structure of this utility model is embedded. As an injection-molded integral part, it no longer requires glue, and its firmness is strengthened to more than 30 million cycles.
