Description

Technical Field

[0001] The utility model relates to the technical field of electronic product accessories, in particular to an independent key structure for supporting the capacitive touch keys of electronic products. Background Technique

[0002] Electronic products are related products based on electric energy. Electronic products are a broad category, covering various devices from consumer electronic products to production electronic products. These products were mainly based on electron tubes as basic components in the early stage. However, with the rapid development of technology, integrated circuits and the Internet, electronic products have not only become smaller in size but also more powerful in function;

[0003] The classification of electronic products can be further subdivided into communication electronic products, entertainment electronic products, work and learning electronic products, and emerging electronic products, etc. In existing communication electronic products, such as mobile phones, tablet computers or smart watches, capacitive touch keys are used. The keys are mainly based on capacitive touch technology, that is, when the user's finger is placed on the key and moved up and down, the capacitive touch key can absorb a small amount of current through the contact point during the hand movement, causing a voltage drop at the corner electrode, and achieving the purpose of touch control by sensing the weak current of the human body. This technology does not rely on physical contact, provides high sensitivity and response speed, and has good durability and accuracy at the same time;

[0004] This technology is widely used in existing electronic products. However, most of the above-mentioned communication electronic products are equipped with protective covers when in use. When such electronic products are covered with protective covers, their touch screen keys will be blocked by the protective covers, affecting the normal use of this function. Even if the protective cover has a reserved groove in the area of the touch sliding key, the reserved groove cavity cannot protect the touch area, resulting in certain inconvenience in use. For this reason, the utility model proposes an independent key structure for supporting the capacitive touch keys of electronic products. Content of the Utility Model

[0005] The purpose of the utility model is to provide an independent key structure for supporting the capacitive touch keys of electronic products, so as to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an independent key structure for supporting the capacitive touch keys of electronic products, including a glass sheet, the back of the glass sheet is fixedly connected with a PCB circuit board, an inner ring is sleeved outside the glass sheet and the PCB circuit board, the outside of the inner ring is fixedly connected with a covered silicone rubber ring, the covered silicone rubber ring is provided with an inward concave inclined surface, and the back of the PCB circuit board protrudes to contact with the electronic product key.

[0007] Preferably, an outer ring is fixedly sleeved outside the beer sleeve silicone ring.

[0008] Preferably, a circle of embedded grooves is formed on the outer surface of the middle part of the outer ring.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] After the present utility model is installed on the electronic product protective cover, it can effectively protect the touch key area of the electronic product, prevent the touch screen keys from being directly exposed to the external environment, have good protection performance, and ensure the normal use of the touch function while protecting the touch area, greatly improving the practicability of the present utility model and being convenient to use;

[0011] Moreover, the PCB circuit board of the present utility model is externally sleeved with a beer sleeve silicone ring. The beer sleeve silicone ring adopts an inward concave inclined surface design, and at the same time, the back surface of the PCB circuit board protrudes vertically to contact the electronic product keys. Through the concave structure design of the beer sleeve silicone ring and the protruding PCB circuit board, in actual use, the PCB circuit board can be closely and concavely attached to the touch screen keys of the electronic product, avoiding gaps between the two, thereby ensuring the normal contact and conduction effect of the current, ensuring the sensitivity of the touch, improving the use sensitivity of the present utility model, having better practicability, and at the same time, the beer sleeve silicone ring can automatically elastically reset after the keys of the present utility model are pressed, ensuring the normal key resilience;

[0021] Please refer to Figures 1 - 3 , an embodiment provided by the present invention: an independent button structure for supporting the touch-sensing button of an electronic product, including a glass sheet 1. The back of the glass sheet 1 is fixedly connected with a PCB circuit board 2. The PCB circuit board 2 is a PCB metal conductive foil. During actual use, the back of the PCB circuit board 2 protrudes to contact the touch-sensing button of the electronic product;

[0022] Furthermore, an inner ring 3 is sleeved outside the glass sheet 1 and the PCB circuit board 2, and an overmolded silicone rubber ring 4 is fixedly connected to the outside of the inner ring 3;

[0023] Among them, the overmolded silicone rubber ring 4 is provided with an inward concave inclined surface;

[0024] With this structural design, through the concave structure design of the overmolded silicone rubber ring 4 and the protruding PCB circuit board 2, during actual use, the PCB circuit board 2 can be closely attached to the touch-sensitive sliding screen button of the electronic product, avoiding the appearance of gaps between the two, thereby ensuring the normal conduction effect of the current;

[0025] Meanwhile, the double-injected silicone ring 4 can automatically perform elastic reset after the button of the present utility model is pressed, ensuring normal button rebound and reset.

[0026] In this embodiment, in order to ensure that the button of the present utility model can be integrally and compatibly installed in the touch groove reserved in the electronic product protective case, an outer ring 5 is fixedly sleeved outside the double-injected silicone ring 4. Among them, the inner ring 3 and the outer ring 5 are metal rings or plastic rings;

[0027] The inner ring 3 is used as a connection structure between the glass sheet 1, the PCB circuit board 2 and the outer ring 5 for connecting the inner ring structure and the outer ring 5;

[0028] As another implementation scheme of the present utility model, the inner ring 3 can also be removed, that is, the glass sheet 1 and the PCB circuit board 2 are directly connected to the outer ring 5, which can also ensure normal use effect;

[0029] Furthermore, a circle of embedded grooves 6 is opened on the outer surface of the middle part of the outer ring 5;

[0030] With this structural design, when the present utility model needs to be installed in the groove reserved in the electronic product protective case, the outer ring 5 of the present utility model can be snap-fitted into the groove of the protective case through the embedded groove 6. At this time, the PCB circuit board 2 is in contact with the touch screen button of the electronic product, and one side of the glass sheet 1 can be in contact with the user's hand during use, ensuring that the present utility model can be compatibly installed on the electronic product protective case for use;

[0031] According to different usage situations, during the production of the present utility model, the sizes of the outer ring 5 and the embedded groove are adaptively produced according to the sizes of the actually used electronic product protective cases, ensuring that the present utility model can be applied to different models of electronic product protective cases, ensuring model applicability and improving the applicable range.

[0032] Working principle: The independent button structure of the present utility model, through the structural design of the outer ring 5 and the embedded groove 6, can be snap-fitted and installed on the adapted electronic product protective case for supporting use;

[0033] After the button is snap-fitted, one side of the glass sheet 1 faces outward, and the back of the PCB circuit board 2 protrudes and is in contact with the touch sensing button of the electronic product;

[0034] During use, the user touches the glass sheet 1 with their hand, and the microcurrent on the finger skin can conduct a weak current through the glass sheet 1 and the PCB circuit board 2, so as to transfer the weak current generated by the touch to the touch button of the electronic product. The touch button of the electronic product identifies the voltage drop of the corner electrode for the conducted weak current, so that the electronic product can perform function operations such as screen sliding and switching according to the actual current signal, thereby ensuring the normal use of the present utility model;

[0035] After the present utility model is installed on the electronic product protective cover, it can effectively protect the touch button area of the electronic product, prevent the touch screen sliding button from being directly exposed to the external environment, have good protection performance, and ensure the normal use of the touch function while achieving the protection effect of the touch area, greatly improving the practicality of the present utility model and being convenient to use;

[0036] Moreover, the external of the PCB circuit board 2 of the present utility model is sleeved with a silicone ring 4 with an inward concave inclined surface design. At the same time, the back of the PCB circuit board 2 protrudes vertically from the silicone ring 4 to contact the touch button of the electronic product. Thus, through the concave structure design of the silicone ring 4 and the protruding PCB circuit board 2, during actual use, the PCB circuit board 2 can be closely and concavely fitted with the touch screen sliding button of the electronic product, avoiding gaps between the two, thereby ensuring the normal contact conduction effect of the current, ensuring the sensitivity of the touch, improving the use sensitivity of the present utility model, and having better practicality;

[0037] At the same time, the silicone ring 4 can automatically perform elastic reset after the button of the present utility model is pressed, ensuring the normal button rebound use effect;

[0038] Finally, the present utility model can facilitate the installation and disassembly of the protective cover through a snap-in installation method, with a convenient structure to use and a high degree of cooperation, and is suitable for popularization and use.

[0039] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
