Description

Electronic devices covered with trim on the touch panel

technical field

The invention relates to an electronic device, especially an electronic device with a decorative plate unit made of plastic sheet, which can reduce the height difference between the decorative plate unit and the computer mainframe casing.

Background technique

With the advancement of science and technology, many devices that can generate control signals have been developed for portable electronic products in recent years, so that the cursor (cursor) on the display can be moved, such as mouse, track ball (track ball), joystick ( joy-sticks), touch pad (touch pad), and track point (track point) and so on.

Among them, the invention of the touch pad allows users to control the position of the cursor on the computer screen only by sliding their fingers on the surface of the touch pad and operating with several touch pad buttons. For example, the function of the left and right buttons of the mouse is a very convenient invention.

As shown in FIG. 1 , a known electronic device 1 (such as a computer) is provided with a touch sensor panel 12 on a main body casing 11, and around the touch sensor panel 12, a metal material touch panel is glued. Border 13 (touch pad frame). In order to prevent the touch panel frame of metal material from blocking the sensing of the touch sensor panel 12 , the touch panel frame of metal material will not be disposed on the touch sensor panel 12 .

Please refer to FIG. 2, since the touch panel frame 13 can only surround the touch sensor panel 12, this makes the touch panel frame 13 glued on the computer main body casing 11, and the touch sensor panel 12, A very obvious height difference d1 is formed. Here, the touch panel frame 13 is made of metal material. If the thickness is larger, the height difference d1 between the touch panel frame 13 and the touch sensor panel 12 is also larger. As mentioned above, not only is there easy to accumulate dust between the touch panel frame 13 and the touch sensor panel 12, but also the integrity of the electronic device 1 is insufficient, thereby affecting the aesthetic feeling of the design.

In view of the above-mentioned problems, the inventor is thinking of an "electronic device" that can solve the shortcomings of the obvious height difference between the frame of the touch panel and the touch-sensitive panel, and easy dust accumulation.

Contents of the invention

In view of the above problems, the object of the present invention is to provide an electronic device, especially an electronic device with a decorative plate unit made of plastic sheet, which can reduce the height difference between the decorative plate unit and the computer mainframe casing.

To achieve the above purpose, the electronic device according to the present invention includes a casing, a sensing unit, and a trim unit. Wherein, the casing has at least one opening, the sensing unit is arranged inside the casing, and is located below the opening, the decorative plate unit has a first part and a second part, the decorative plate unit covers the opening, the first part and the sensor The measuring units face each other, and the second part is arranged around the first part and connected with the casing.

Based on the above, the electronic device of the present invention has the decorative plate unit made of plastic material by integral stamping, and the thickness of the decorative plate unit is relatively thin, so the height difference between the decorative plate unit and the computer mainframe casing can be reduced. Compared with the known technology, the electronic device of the present invention not only reduces the height difference between the decorative panel unit and the computer mainframe casing, but also increases the integrity of the design. In addition, the trim unit is not only connected to the computer main body casing, but also faces the sensing unit, which not only reduces the height difference, but also prevents dust from accumulating on the frame of the touch panel and the touch sensor in the known technology. between panels. Moreover, the decorative panel unit made by stamping technology has thin material and relatively low cost, so the production cost is also reduced.

Detailed ways

In order to make the content of the present invention easier to understand, a preferred embodiment of the electronic device of the present invention will be described below with reference to related drawings.

Please refer to FIG. 3 , the electronic device 2 of the present invention includes a casing 21 , a sensing unit 22 , and a trim unit 23 .

The housing 21 refers to the housing of the portable information processor, such as the main housing of the notebook computer. The housing 21 has at least one opening 211 .

The sensing unit 22 is disposed inside the casing 21 and located below the opening 211 . The sensing unit 22 is a touch panel, and a plurality of sensing circuits are distributed on the surface of the touch panel. When an object (such as a finger or a stylus) moves on the touch panel, the capacitance or resistance of the sensing circuit changes. A signal is generated to control the movement of the cursor.

The trim unit 23 has a first portion 231 (gray portion) and a second portion 232 , and the trim unit 23 covers the opening 211 . The trim unit 23 is made of polycarbonate (PC) or polyethylene terephthalate (PET), and is molded by stamping to make a thinner trim unit 23 . In this embodiment, the thickness of the trim unit 23 is less than about 0.6 mm.

As shown in FIG. 3 , the first portion 231 of the trim unit 23 faces the sensing unit 22 , and the second portion 232 is disposed around the first portion 231 and connected to the casing 21 . In addition, the second part 232 is connected to the housing 21 by using an adhesive or a double-sided tape to bond the second part 232 to the housing 21 . In addition, the first part 231 and the second part 232 are integrally formed, and can be formed by stamping. Furthermore, since the first part 231 and the second part 232 are integrally formed, dust can be prevented from affecting the sensitivity of the sensing unit 22 .

As shown in FIG. 4, the electronic device 2 of the present invention further includes a spacer 24, which is arranged between the sensing unit 22 and the trim unit 23, so as to maintain a certain distance between the sensing unit 22 and the trim unit 23. spacing. Due to the use of plastic materials, the thickness of the trim unit 23 that is integrally stamped and formed is relatively thin. Thus, when the user exerts a large force on the trim unit 23, the trim unit 23 may be broken due to its small mechanical strength. Bending occurs, which in turn leads to a decrease in sensitivity. In other words, the gasket 24 is used in this embodiment to strengthen the mechanical strength of the trim unit 23 .

In addition, as shown in FIG. 4 , there is no obvious height difference between the first part 231 and the second part 232 of the decorative plate unit 23, and there is only a very small height difference d2 between them as a whole. The integrity of the design of the electronic device 2 is also increased.

To sum up, the electronic device of the present invention has a decorative plate unit made of plastic material by integral stamping, and the thickness of the decorative plate unit is relatively thin, so the height difference between the decorative plate unit and the computer mainframe casing can be reduced. Compared with the known technology, the electronic device of the present invention not only reduces the height difference between the decorative panel unit and the computer mainframe casing, but also increases the integrity of the design. In addition, the trim unit is not only connected to the computer main body casing, but also faces the sensing unit, which not only reduces the height difference, but also prevents dust from accumulating on the frame of the touch panel and the touch sensor in the known technology. between panels. Moreover, the decorative panel unit made by stamping technology has thin material and relatively low cost, so the production cost is also reduced.

The above descriptions are illustrative only, not restrictive. Any equivalent modification or change made without departing from the spirit and scope of the present invention shall be included in the scope of the patent application.
