Description

Technical Field

[0001] This utility model belongs to the field of elevator button technology, and specifically relates to an elevator button. Background Technology

[0002] Elevator buttons are a core component of elevator human-machine interaction, and their performance directly affects the user experience and the reliability of elevator operation. Existing elevator buttons generally suffer from the following problems:

[0003] 1. Uneven tactile feedback: Most buttons use a single spring or ordinary contact spring to achieve reset, which can easily result in some areas feeling too hard or too soft when pressed, especially in the edge areas of the buttons, where the difference in tactile feedback is more obvious.

[0004] 2. Poor structural stability: The components are mostly fixed with simple clips or glue, which are prone to loosening after long-term use, causing the buttons to stick or fail to be triggered normally;

[0005] 3. Cumbersome installation: The overall button assembly requires multiple positioning steps, and the fixing method to the elevator panel is complicated, which increases installation time and maintenance difficulty;

[0006] 4. Low reset reliability: Some reset components (such as metal springs) are prone to failure due to oxidation and deformation, causing the button to fail to return to the initial position and affecting normal use.

[0007] Therefore, further improvements will be made to address the aforementioned issues. Utility Model Content

[0008] The main purpose of this utility model is to provide an elevator button that is designed to have a uniform tactile feel, stable structure, convenient installation and reliable reset, so as to meet the elevator industry's demand for improved component performance and user experience.

[0009] To achieve the above objectives, this utility model provides an elevator button, comprising a letter plate, a transmission component, an outer frame, a spring pad, and a circuit board, wherein:

[0010] The top of the transmission component is provided with a first placement groove and the text piece is installed in the first placement groove. The side of the transmission component is provided with a plurality of clips and matching parts facing away from the top. The clips and matching parts are arranged alternately. The clips are provided with clip ends and the matching parts are provided with grooves facing the center of the transmission component.

[0011] The outer frame surrounds the side of the transmission component, and the inner wall of the outer frame is provided with a plurality of locking blocks and fixing ends. The locking blocks and fixing ends are staggered. The top of the locking end is in close contact with the bottom of the locking block. The fixing end is located in the groove and the fixing end is provided with a first fixing hole.

[0012] The circuit board is mounted on the bottom of the outer frame and has a touch switch and several second fixing holes. The touch switch is surrounded by the side of the transmission member and the second fixing holes are aligned with the first fixing holes one by one. The spring pad is surrounded by the side of the transmission member, the top of the spring pad is in close contact with the transmission member and the bottom of the spring pad is in close contact with the circuit board.

[0013] As a further preferred embodiment of the above technical solution, the spring pad surrounds the touch switch.

[0014] As a further preferred embodiment of the above technical solution, the text image is provided with key information.

[0015] As a further preferred technical solution to the above technical solution, it also includes a fastener, wherein the inner ring of the fastener is threadedly connected to the outer ring of the outer frame.

[0016] As a further preferred embodiment of the above technical solution, the spring pad is made of silicone.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. Uniform and soft touch: The ring-shaped silicone spring pad surrounds the touch switch, so the force is evenly distributed in all areas of the spring pad when pressed, which can achieve a consistent touch throughout the button area. Moreover, the silicone material is softer than the metal spring, improving the user's pressing experience.

[0019] 2. Stable and reliable structure: The transmission components achieve axial positioning through "clamping parts-clamping blocks" and circumferential positioning through "matching parts-fixed ends". The circuit board is rigidly fixed to the outer frame with bolts. All components are connected without looseness, avoiding jamming or failure after long-term use.

[0020] 3. Excellent reset performance: The silicone spring pad has excellent elastic recovery force, and is resistant to aging and deformation. Even with long-term high-frequency use (such as pressing the button more than a thousand times a day in an elevator), it can still ensure that the button smoothly rebounds to the initial position, and the service life can reach more than 5 years.

[0021] 4. Easy installation and maintenance: The button and elevator panel can be quickly installed through the threaded connection of the fastener. Disassembly only requires rotating the fastener in the opposite direction, without disassembling other parts, thus reducing maintenance costs. Attached Figure Description

Detailed Implementation

[0029] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0030] This utility model discloses an elevator button. The specific embodiments of the utility model will be further described below with reference to preferred embodiments.

[0031] In the embodiments of this utility model, those skilled in the art will note that bolts and the like involved in this utility model can be considered as prior art.

[0032] Preferred embodiment.

[0033] like Figure 1-6 As shown, this utility model discloses an elevator button, including a text panel 1, a transmission component 2, an outer frame 3, a spring pad 4, and a circuit board 5, wherein:

[0034] The top of the transmission component 2 is provided with a first placement groove 21 and the text piece 1 (with direction and elevator display function) is installed in the first placement groove 21. The side of the transmission component 2 is provided with a plurality of clips 22 and matching parts 23 facing away from the top. The clips 22 and matching parts 23 are arranged alternately. The clips 22 are provided with a clip end 221 and the matching parts 23 are provided with a groove 231 facing the center of the transmission component.

[0035] The outer frame 3 surrounds the side of the transmission member 2, and the inner wall of the outer frame 3 is provided with a plurality of locking blocks 31 and fixing ends 32. The locking blocks 31 and the fixing ends 32 are staggered. The top of the locking end 221 is in close contact with the bottom of the locking block 31 (restricting the transmission member from moving upward inside the outer frame). The fixing end 32 is located in the groove 231 and is provided with a first fixing hole 33.

[0036] The circuit board 5 is mounted on the bottom of the outer frame 3 and is provided with a touch switch 51 and several second fixing holes 52. The touch switch 51 is surrounded by the side of the transmission member 2 and the second fixing holes 52 are aligned with the first fixing holes 33 one by one (the circuit board is fixedly mounted on the bottom of the outer frame by bolts, first and second fixing holes). The spring pad 4 is surrounded by the side of the transmission member 2. The top of the spring pad 4 is in close contact with the transmission member 2 and the bottom of the spring pad 4 is in close contact with the circuit board 5 (when the button needs to be pressed, a downward force is applied to the text piece, thereby driving the transmission member to move down inside the outer frame until the transmission member moves once to touch the switch and trigger the elevator information. At this time, the spring pad is compressed between the transmission member and the circuit board. After the text piece is released, the transmission member is reset due to the restoring force of the spring pad).

[0037] Specifically, the spring pad 4 surrounds the touch switch 51 (the spring pad is a ring, which makes the transmission component feel softer and the touch feel uniform in all directions).

[0038] More specifically, the text slice 1 is equipped with button information.

[0039] Furthermore, it also includes a fastener 6, the inner ring of which is threadedly connected to the outer ring of the outer frame 3 (thereby installing the entire elevator button in a preset position).

[0040] Furthermore, the spring pad 4 is made of silicone.

[0041] The transmission components are made of PC injection molding, while the outer frame and fixing components are made of ABS plastic, and the outer frame is electroplated.

[0042] Regarding this utility model:

[0043] Press-triggered: When the user applies downward pressure to the text card, the text card drives the transmission component to move downward along the outer frame axis. At this time, the spring pad is squeezed and compressed by the transmission component and the circuit board. When the bottom of the transmission component contacts and presses the touch switch of the circuit board, the touch switch closes and outputs the corresponding elevator control signal (such as floor selection signal, up and down command signal).

[0044] Reset process: After the user releases the text piece, the spring pad gradually extends under its own elastic restoring force, pushing the transmission component upward; until the locking end of the side of the transmission component is once again in close contact with the bottom of the locking block on the inner wall of the outer frame, the transmission component stops moving upward and returns to the initial position. At this time, the touch switch is disconnected, waiting for the next press.

[0045] It is worth mentioning that the technical features such as bolts involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0046] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
