Description

Technical Field

[0001] This utility model relates to the field of control equipment technology, specifically to a lever button device. Background Technology

[0002] In the personal care and massage equipment sector, users are placing increasingly higher demands on the human-computer interaction experience of products. Traditional button controls typically use simple mechanical switches or resistive potentiometers to achieve input functions. While these devices are simple in structure, they have limitations in terms of accuracy, durability, and user experience. With technological advancements, new components such as 3D potentiometers have been introduced into button designs to provide more precise input feedback and a smoother operating experience.

[0003] The shortcomings of existing technology:

[0004] 1. Limited response accuracy: Traditional button devices rely on basic mechanical switches, which have low resolution and cannot accurately capture the user's operating intentions. This limitation is particularly evident in application scenarios that require fine adjustment, such as adjusting massage intensity or speed.

[0005] 2. Short lifespan: Ordinary buttons are prone to wear and tear and poor contact after prolonged use, affecting the reliability and lifespan of the device. Especially in massagers or similar products that are used frequently, the durability of the buttons is directly related to the overall quality of the product.

[0006] 3. Poor user experience: Traditional buttons lack a balancing mechanism, which may result in uneven force when pressed, leading to a poor feel; at the same time, due to the lack of a good reset mechanism, the buttons may not be able to return to their initial position quickly and accurately, reducing the smoothness of operation.

[0007] 4. Inconvenient installation and maintenance: Some existing button devices have complex internal structures and are difficult to assemble. Once a malfunction occurs, the repair cost is high and inconvenient.

[0008] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content

[0075] The two ends of the balance bar 11 are engaged in the first locking block 12;

[0076] The balance bar 11 is located below the button 1 to keep the force balanced at each point of the button 1 during the pressing process, so as to ensure that the button 1 is pressed down smoothly.

[0077] The balance bar 11 is made of metal.

[0078] The balance bar 11 is in the shape of a "U".

[0080] The bracket 7 is provided with a vertical through-hole 14 at the position corresponding to the spring piece 13;

[0081] The spring piece 13 passes through the bayonet 14 and hooks onto the lower side of the bracket 7.

[0082] The external device includes a massager.

[0083] The principle of this utility model is as follows:

[0084] The lever button 1 device described in this utility model achieves precise control of the motion parameters of external devices such as massagers through a series of precisely designed mechanical and electronic components. The core of this device lies in the interaction between the button 1 post 2 and the 3D potentiometer 3, and the response of the IC on the main control board 5 to changes in the potentiometer's state.

[0085] Workflow

[0086] Initial state:

[0087] Button 1 is in its natural, unpressed position and is held at its original height by an elastic element (such as spring 6).

[0088] The balance bar 11 is located below the button 1 to ensure that the force is evenly distributed on all points on the surface of the button 1, ready to respond to the user's operation.

[0089] 3D potentiometer 3 is in the default state, and its crank 4 is not subjected to external force, so it outputs a stable coded value to the IC on the main control board 5.

[0090] Press the button:

[0091] When the user presses button 1, button 1 moves downward, and its post 2 descends accordingly, pressing against the rocker arm 4 of the 3D potentiometer 3.

[0092] When the crank 4 is subjected to pressure from the post 2 of the button 1, it deflects, which changes the internal resistance distribution of the 3D potentiometer 3, thereby causing the output encoded value to change.

[0093] The IC on the main control board 5 monitors the changes in the encoded values ​​of the 3D potentiometer 3 in real time, and interprets the operational intent represented by these changes according to the preset algorithm or program logic.

[0094] The IC then issues instructions to adjust the operating parameters of the external device, such as changing the vibration frequency or intensity of the massager, or adjusting the extension and retraction speed of the massager.

[0095] Reset process:

[0096] When the user releases button 1, the elastic element (such as spring 6) located below button 1 provides an upward elastic force, pushing button 1 back to its initial position.

[0097] As button 1 and post 2 rise, the crank 4 of 3D potentiometer 3 returns to its original position, reverting to the default state and ceasing further control and adjustment of external devices.

[0098] The design of the spring 13 ensures that the button 1 is firmly installed on the bracket 7 without hindering the up and down movement of the button 1; the metal balance bar 11 ensures that the button 1 is pressed down and rebounded smoothly throughout the process, avoiding tilting or jamming.

[0099] Key components and their functions

[0100] Button 1 and pillar 2: As the user interface, they are responsible for receiving user input and converting physical displacement into operation of 3D potentiometer 3.

[0101] 3D potentiometer 3: Used as a sensing element, it can sense the pressure change applied by the button 1 and the post 2, and convert it into an electrical signal that can be recognized by the main control board 5.

[0102] Main control board 5 and IC: As the core part of the control system, it is responsible for processing the data received from 3D potentiometer 3 and controlling the behavior of external devices accordingly.

[0103] Elastic elements (such as spring 6): provide the necessary restoring force so that button 1 can automatically return to the initial position after each operation, ensuring smooth continuous operation.

[0104] Balance bar 11: Ensures that button 1 remains horizontal during the pressing process, preventing tilting or instability caused by uneven force, and improving user experience.

[0105] The bracket 7, cylinder, spring 13, and barb together form a stable structural frame, which not only supports the entire button 1 device, but also ensures the correct relative position and reliable connection between the various components.

[0106] In summary, the lever button 1 device of this utility model, through the integration of advanced 3D potentiometer 3 technology and a carefully designed mechanical structure, achieves a bridge function between efficient, accurate and reliable user input and external device control.

[0107] The above description is only a preferred embodiment of the present utility model and does not limit the scope of the present utility model.
