Description

Touch panel module and electronic computer

Technical field

The present invention relates to the field of input devices, and in particular, to an input device with a touch function.

Background technique

With the rapid development of science and technology, the vigorous development of electronic equipment has brought a lot of convenience to human life. Therefore, how to make the operation of electronic equipment more humane is an important issue. For example, common electronic devices in daily life include laptop computers, mobile phones, satellite navigation devices, etc. As the storage capacity and processor computing performance of many electronic devices have greatly improved, their functions have become increasingly powerful and complex. In order to efficiently operate multiple electronic devices, manufacturers of electronic devices use touch panels as input devices to operate multiple electronic devices.

Please refer to FIG. 1 , which is a schematic structural diagram of a conventional notebook computer and its touch panel module. The touch panel module 1 is disposed in the casing 21 of the notebook computer 2 and is at least partially exposed to the outside for the user to touch and operate the notebook computer 2. For example, the user can touch the touch panel module 1 with his fingers and touch the touch panel module 1. The touchpad module 1 can be slid to move the cursor 23 on the screen 22, and the notebook computer 2 can also perform specific functions by pressing the touchpad module 1. Therefore, the touchpad module 1 can replace the function of the mouse, so that the user does not need to The inconvenience caused by carrying or installing an additional mouse.

Please refer to FIG. 2 and FIG. 3 simultaneously. FIG. 2 is a conceptual diagram of the touch panel module shown in FIG. 1 when it is not pressed. FIG. 3 is a conceptual diagram of the touch panel module shown in FIG. 2 after being pressed. The casing 21 of the notebook computer 2 has an inwardly recessed frame 24, and the opposite sides of the frame 24 are respectively provided with support structures 241 and trigger parts 242 extending into the frame 24, and the first end 11 of the touch panel module 1 A metal dome switch is provided, and the second end 12 of the touch panel module 1 is connected to the support structure 241 . When the user touches the touch panel module 1 , the first end 11 of the touch panel module 1 swings downward relative to the triggering part 242 with the support structure 241 as a fulcrum, so that the metal dome of the touch panel module 1 The elastic switch 13 resists the triggering portion 242 of the frame 24, thereby triggering the metal dome elastic switch 13 and generating a knocking feedback sound. In addition, when the metal dome elastic switch 13 is triggered, the touch panel module 1 will output a switch control signal to the notebook computer 2, thereby causing the notebook computer 2 to perform the corresponding function. When the user no longer touches the touch panel, When the touch panel module 1 is removed, the first end 11 of the touch panel module 1 will swing upward relative to the triggering portion 242 according to the elastic force of the support structure 241 , so that the touch panel module 1 returns to its original position.

However, a shortcoming of the known touch panel module 1 is that after being touched, the touch panel module 1 may cause different moving strokes at different positions, thus causing operational obstruction. Taking FIG. 1 as an example, area A and area B are respectively located at two corners of the touch panel module 1 and are also located on opposite sides of the first end 11 of the touch panel module 1. When the user touches A When there is any one of the area and the B area, the downward movement amplitude of the A area is too different from the downward movement area of the B area, which leads to a poor operating feel and even makes the metal dome elastic switch 13 unable to be effectively operated. trigger.

In order to improve the above-mentioned defects, another touch panel module has been proposed. Please refer to FIG. 4 , which is a conceptual side view of another conventional touch panel module. The touch panel module 1' includes a touch panel assembly 14, a drag frame 15 and a plurality of silicone rubbers 16. A tactile feedback sensor 141 (haptics) is installed on the bottom surface of the touch panel assembly 14, and the drag frame 15 is disposed on the touch panel. The bottom of the touch panel assembly 34 is fixed in the frame 24 , and a plurality of silicones 16 are disposed between the touch panel assembly 14 and the carriage 15 . When the user touches any position of the touch panel module 1', the touch panel module 1' will move downward to push and compress the silicone 16. At this time, the tactile feedback sensor 141 is triggered to cause the touch panel module to 1' outputs a switch control signal to the notebook computer 2, causing the notebook computer 2 to perform the corresponding function. When the user no longer touches the touch panel module 1', the touch panel module 1 will produce a sound according to the compression of the silica gel. The elastic force causes it to swing upward relative to the trailer 32 and then return to its original position.

However, in the process of the touch panel module 1', the silicone 16 is combined with the touch panel assembly 14 and the carriage 15 through the colloid 17, which must be pressed by a jig and baked for more than 30 minutes. Therefore, using silicone 16 as the elastomer to provide elastic force after the touch panel module 1 is compressed will make the process of the touch panel module 1' more time-consuming and cumbersome. In addition, if foreign matters (such as oil stains) remain on the touch panel assembly 14 at the joint with the silicone 16 due to poor cleaning, the silicone 16 will not be able to adhere closely to the touch panel assembly 14 and will easily fall off. This is a problem that currently affects the touch panel assembly. Control board module 1' is a significant factor in yield.

According to the above description, there is room for improvement in known touch panel modules and electronic computers having touch panel modules.
