Description

Technical Field

[0001] This utility model relates to the field of sensor button technology, specifically to an anti-drop touch sensor button. Background Technology

[0002] In existing communication electronic products, such as mobile phones, tablets, or smartwatches, capacitive touch-sensitive buttons are used. These buttons are mainly based on capacitive touch technology, which means that when the user's finger is placed on the button and moved up and down, the capacitive touch-sensitive button can absorb a small amount of current through the contact point when the hand moves, causing a voltage drop at the corner electrode. By sensing the weak current of the human body, the touch purpose is achieved. This technology does not rely on physical contact, provides high sensitivity and response speed, and also has good durability and accuracy. This technology is widely used in existing electronic products. In order to be used with touch-sensitive buttons, most mobile phone cases are equipped with independent touch buttons. These buttons are used by the user's hand to touch a thin glass sheet. The microcurrent on the skin of the finger can be conducted through the glass sheet and PCBA board. In this way, the weak current generated by the touch can be transmitted to the touch button of the electronic product. The touch button of the electronic product identifies the voltage drop of the corner electrode of the conducted weak current, and then makes the electronic product perform functions such as swiping and switching based on the actual current signal. However, the button structure used with existing mobile phone cases mostly uses a simple limiting structure to limit the connection between the glass sheet and the PCBA board. The two lack an anti-detachment structure, resulting in poor stability. Under prolonged use or forceful sliding, the glass sheet is prone to detachment, affecting the touch effect and potentially scratching the user, thus having certain shortcomings. Therefore, this utility model proposes an anti-detachment touch sensing button. Utility Model Content

[0016] Please see Figure 1-4 One embodiment of this utility model is an anti-drop touch-sensitive button, comprising an alloy shell 1, with a plastic frame 2 fixedly installed inside the alloy shell 1. See the attached instruction manual for details. Figure 3 as well as Figure 4 As shown, a layer of adhesive 3 is coated on the outer wall of the front of the plastic frame 2. The adhesive layer 3 is a conductive adhesive layer with a thickness between 0.3-0.5mm. A glass plate 4 is set inside the plastic frame 2. The plastic frame 2 is fitted and covered on the outside of the glass plate 4. The back of the glass plate 4 is in adhesive contact with the adhesive layer 3. This structural design, in this utility model, involves a plastic frame 2 fitted around the outside of the glass plate 4. The plastic frame 2 provides external protection for the glass plate 4, effectively preventing it from detaching. This provides a certain degree of frame protection and initial reinforcement. Simultaneously, the front of the plastic frame 2 is coated with an adhesive layer 3, which adheres to the back of the glass plate 4, thus bonding the glass plate 4 to the plastic frame 2.

This also extends the overall lifespan of the button and prevents scratches or discomfort caused by the glass plate 4 falling off, improving safety and comfort. Overall, this design offers enhanced usability and better practicality.

[0017] In this embodiment, to ensure the normal operation of the touch button, please refer to the appendix of the instruction manual for details. Figure 4 As shown, a PCBA board 6 is provided on the back of the plastic frame 2. A silicone sleeve 5 is fitted over the PCBA board 6. A limiting groove is provided on the outer side of the PCBA board 6, and a limiting protrusion 7 is provided on the inner side of the silicone sleeve 5. The silicone sleeve 5 is connected to the limiting groove of the PCBA board 6 through the limiting protrusion 7. In this way, the silicone sleeve 5 can work with the alloy shell 1 to provide external protection for the PCBA board 6, which has good silicone protection characteristics and ensures normal use. At the same time, when the silicone sleeve 5 is pressed and deformed, it has a certain degree of elasticity, which can help the button to rebound when pressed, and has a good silicone elasticity effect.

[0018] In this embodiment, the outer surface of the alloy shell 1 is provided with a slot 8 for fitting and engaging with the mobile phone shell. In actual use, the sensor button of this utility model can be limited and engaged in the fitting mobile phone shell through the slot 8 of the alloy shell 1, thereby completing the snap-fit ​​installation of the button and ensuring normal use characteristics.

[0019] In this embodiment, in order to improve the overall strength of the outer shell of the sensing button, the alloy shell 1 is made of aluminum alloy. The aluminum alloy shell can effectively improve the overall strength of the shell, and at the same time, it has the characteristics of lightweight use. While ensuring the strength of the shell, it can effectively reduce the overall weight of the button, and the material is more practical.

[0020] Working principle: The inductive button of this utility model can be limited and locked in the matching mobile phone case through the slot 8 of the alloy shell 1, thereby completing the snap-fit ​​installation between the button and the mobile phone case and ensuring normal use. In use, when a user touches the glass plate 4, the microcurrent on the skin of the finger can be conducted weakly through the glass plate 4, the adhesive layer 3, and the PCBA board 6. This weak current generated by the touch can be transmitted to the touch buttons of the electronic product. The touch buttons of the electronic product identify the voltage drop of the conducted weak current through the corner electrode, and then perform functions such as swiping and switching based on the actual current signal. This allows the touch buttons of the electronic product to be used normally. This is a mature existing technology, and this specification will not elaborate further. This invention features a plastic frame 2 fitted around the outside of a glass plate 4. This plastic frame 2 provides external protection for the glass plate 4, effectively preventing it from detaching. It offers basic structural protection and provides initial reinforcement. The front of the plastic frame 2 is coated with an adhesive layer 3, which adheres to the back of the glass plate 4, allowing the glass plate 4 to be bonded to the plastic frame 2. In practical use, the plastic frame 2, in conjunction with the adhesive layer 3... This design effectively reinforces the glass plate 4 through a nested adhesive bonding process, preventing it from detaching during actual use and ensuring the normal operation of the sensor button. It also extends the overall lifespan of the button. Compared to traditional limiting connections, this design, using a plastic frame 2 and adhesive layer 3, effectively enhances the installation and connection strength of the glass plate 4, preventing it from detaching and causing scratches or discomfort. This improves safety and comfort, resulting in a better overall performance and practicality. It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
