Description

touch module

technical field

The invention relates to an input device, in particular to a touch module arranged on a computer.

Background technique

Common traditional computer peripheral input devices include a mouse device, a keyboard device, a trackball device and the like. With the progress of the times, touch modules have been launched on the market, allowing users to directly use their fingers to operate on the touch modules to operate computer systems. The application of the touch module is quite extensive. The touch module has been included in the early notebook computers, which can control the movement of the cursor or click on the image of the user interface, and the notebook computer can be operated without using a mouse. The advantage of the touch module is that it can be operated by the user in an intuitive manner, so as to facilitate the execution of various commands.

Please refer to FIG. 1 , which is a structural diagram of a conventional notebook computer and a touch module. The known touch module 1 is disposed inside the computer case 21 of the notebook computer 2 and partly exposed to the outside for the user's finger to operate the notebook computer 2 by touching. For example, the user can touch the touch module 1 with a finger and slide on the conventional touch module 1 to move the cursor 23 on the screen 22 of the notebook computer 2 . Alternatively, the notebook computer 2 can also be made to perform key functions by pressing the known touch module 1 . Therefore, it can be seen that the known touch module 1 can replace the function of the mouse, so that the user does not need to carry and install the mouse and bring inconvenience.

Next, the internal structure of the known touch module will be described. Please refer to FIG. 1 and FIG. 2 at the same time. FIG. 2 is a schematic side view cross-sectional view of a conventional touch module. The conventional touch module 1 is disposed inside a computer case 21 and partially exposed outside, and includes a frame 11 , a touch panel assembly 12 , a metal support block 13 and a sponge 14 . The frame body 11 is disposed on the computer case 21 and has a protruding portion 111 . The sponge 14 is disposed on one side of the frame body 11 with an adhesive, and the metal support block 13 is also disposed on the sponge 14 through the adhesive. The touch panel assembly 12 is located above the frame body 11 and one end thereof is connected to the metal support block 13 through an adhesive. The touch panel assembly 12 includes a cover plate 121 , a circuit board 122 and a key switch 123 . One end of the circuit board 122 is connected to the metal support block 13 , and the key switch 123 is disposed on the lower surface of the circuit board and located at the other end of the circuit board 122 . The cover plate 121 is disposed on the circuit board 122 and exposed outside the computer case 21 .

Please refer to FIG. 1 , FIG. 2 and FIG. 3 at the same time. FIG. 3 is a schematic side view cross-sectional view of a structure of a known touch module being pressed. When the user touches the touch panel assembly 1 with his fingers, the other end of the touch panel assembly 1 (that is, the end where the key switch 123 is located) is relatively to the computer case 21 with the metal support block 13 and the sponge 14 as the fulcrum. swing down. Wherein, according to the downward pressure of the touch panel assembly 1 , the sponge 14 is pressed and compressed, so that the touch panel assembly 1 swings downward. During the downward swing of the touch panel assembly 1, the key switch 123 on the circuit board 122 is in contact with the protrusion 111 on the frame body 11, and is triggered to generate a corresponding key signal to the notebook computer 2, so that the notebook computer The computer 2 can perform commands corresponding to key signals. When the user's finger no longer touches the touchpad assembly 1, the touchpad assembly 1 swings upwards and returns to the position before being pressed according to the internal elastic force of the key switch 123 and the elastic restoring force of the sponge. Through the above operations, the known touch module 1 can provide button functions to replace the mouse.

In the known touch module 1, since the touch panel assembly 1 is fixed on the metal support block 13, and the soft sponge 14 is arranged under the metal support block 13, although the sponge 14 will be in a compressed state when pressed down, so as to facilitate The touch panel assembly 1 swings, but in actual operation, the sponge 14 is irregularly compressed in various directions, causing the swing of the touch panel assembly 1 to be unstable, thereby affecting the touch feeling of the conventional touch module 1 .

Therefore, there is a need for a touch module that can operate stably.
