Description

Technical Field

[0001] The utility model relates to the technical field of touch buttons, and more specifically, to a sliding touch button of a mobile phone. Background Art

[0002] With the progress of society, people receive more and more information through mobile phones. In daily use, browsing address books, text messages, web pages, chat records, etc. are all achieved through the touch screen of the mobile phone. With the promotion of large-screen mobile phones, these operations often require two hands to complete, which is very inconvenient to use and has low work efficiency.

[0003] The utility model patent with patent announcement number CN204231468U discloses a mobile phone volume adjustment button with a touch screen, comprising a mounting base, an up-adjustment key, and a down-adjustment key. The patent is characterized in that a touch screen is also provided, wherein the up-adjustment key, down-adjustment key, and touch screen are arranged along the length of the mounting base, and the up-adjustment key and down-adjustment key are located at both ends of the touch screen. A wiring port is also provided on the mounting base, and each circuit pin in the wiring port is connected to a circuit pin corresponding to the up-adjustment key, down-adjustment key, and touch screen via a printed circuit. The effect is that a touch screen adjustment function is added to the basis of an ordinary push-button volume adjustment button, specifically for sliding operations in mobile phone application software, realizing interface flipping and continuous adjustment. The structure is simple and modular production can be achieved, making mobile phone operation more convenient and improving efficiency.

[0004] However, in actual use, this structure has problems. When the touch button is used, the capacitance between the human body and the button changes, and the button recognition and triggering are achieved by detecting this change. The capacitance value of traditional touch buttons is usually above 1.5 pico-farads, which leads to the need to improve the trigger sensitivity. Secondly, copper foil is used for conductivity in the existing market during triggering. Although the price is low, the touch key needs to carry a large current and has high stability requirements. Copper foil is prone to overheating, which has a great impact on the trigger sensitivity. Therefore, a mobile phone sliding touch button is proposed. Utility Model Content

This makes the conductivity of the conductive module higher than that of traditional aluminum foil. At the same time, the copper block can carry more electricity, thereby avoiding heat accumulation, thereby further improving the sensitivity and stability of touch button triggering;

[0014] 2. The conductive module is inserted into the installation groove through interference fit, so that the convex ring is clamped in the groove, so that the conductive module is installed and fixed in the touch panel, which improves the installation strength of the conductive module and is not easy to loosen.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] As attached Figure 1-4 The sliding touch button of a mobile phone shown in the figure includes a top plate 1, a card plate 2 is provided at the bottom end of the top plate 1, a card slot 3 is provided between the top plate 1 and the card plate 2, a convex plate 4 is provided at the bottom of the card plate 2, and multiple conductive modules 5 are installed in the convex plate 4. Multiple cylindrical copper blocks are used as conductive modules 5, and the top plate 1, card plate 2 and convex plate 4 made of acrylic plate with a transparent appearance are matched to form a touch panel. The transparent touch panel and the multiple conductive modules 5 are interference fit to form a touch button. The touch panel can be assembled with the mobile phone case as a collected touch button. During installation, the sealing gasket can be used to improve the firmness of the touch panel installation while improving the sealing of the touch button installation.

[0022] The top plate 1 , the card plate 2 and the protruding plate 4 are an integrally formed structure to form a touch panel, and a plurality of mounting slots 6 are provided at the bottom of the touch panel.

[0023] The touch panel is made of acrylic material and has a transparent structure. The capacitance value of the touch panel is tested to be less than 0.5 pico-farads, which makes the capacitance value of the entire touch button lower and improves the touch sensitivity. At the same time, the transparent design can improve the aesthetics after installation.

[0024] The conductive module 5 is a copper block, and both ends of the conductive module 5 have chamfered edges. The copper block used in the conductive module 5 has been cleaned to reduce resistance. At the same time, it has been cold-processed to reduce crystal defects in the copper block, thereby improving the conductivity of the copper block. This makes the conductivity of the conductive module 5 higher than that of traditional aluminum foil. At the same time, the copper block can carry a larger amount of electricity, thereby avoiding heat accumulation, thereby further improving the stability of the touch button trigger sensitivity.

[0025] A convex ring 8 is provided at one end of the conductive module 5 , and a groove 7 is provided inside the mounting groove 6 . The conductive module 5 and the mounting groove 6 are interference fit, and the convex ring 8 and the groove 7 are snap-fitted.

[0026] When installing the conductive module 5, one end of the conductive module 5 is directly inserted into the installation groove 6. Under the guidance of the chamfer, the conductive module 5 is squeezed into the installation groove 6, so that the convex ring 8 is clamped in the groove 7, so that the conductive module 5 is installed and fixed in the touch panel, thereby improving the installation strength of the conductive module 5 and preventing it from loosening. At the same time, there is no need to add glue to avoid changing the overall capacitance value of the entire key, so that the capacitance value of the entire touch key is within 0.5 pico-farad, thereby improving touch sensitivity.

[0027] An annular groove is formed on the edge where the protruding plate 4 is connected to the clamping plate 2, and a sealing ring is provided in the annular groove to improve the waterproof performance.
