Touch sensing device

The present invention is a touch sensing device, in particular, a touch sensing device capable of removing abnormal sound when pressed.

In recent years, due to the rapid advancement of the production technology of touch sensing devices, touch panels have been widely used in electronic products, including notebook computers, tablet computers, personal digital assistants, mobile phones or other electronic devices. The touchpad is a user's finger or conductive material such as a stylus that slides or contacts on a smooth panel to cause relative movement of the cursor, absolute coordinate movement or other extensibility functions, such as an input device that simulates a button function.

Please refer to FIG. 1A and FIG. 1B , which are schematic diagrams of a touch sensing device of a prior art electronic device. As shown in FIG. 1A, a touch sensing device 20 is disposed on an electronic device 1, and an upper surface thereof can be divided into a sliding area 211 and key areas 212a and 212b. The user can slide freely on the sliding area 211 to control the cursor, and can press the key area 212a or 212b to perform the key function.

As shown in FIG. 1B, the touch sensing device 20 is assembled on the housing 10 of the electronic device 1, and the housing 10 is provided with a triggering table 11. Touch The sensing device 20 includes a contact layer 21, a circuit board 22, an adhesive layer 23, and a metal layer 24. The lower surface of the circuit board 22 is provided with a touch member 221 . When the user presses the contact layer 21, the contact layer 21 causes the circuit board 22 to sink. When the touch member 221 is pressed against the touch table 11, the touch member 221 is triggered. In this way, the touch sensing device 20 can be made to have a pressing function like a conventional physical button.

However, when using the touch sensing device 20 of the prior art, the user must press the contact layer 21 with a certain force to trigger the button function. However, in the assembly process of the touch sensing device 20, since the assembly tolerance cannot be accurately predicted, the size of the gap between the touch member 221 and the touch table 11 is not expected after the assembly is completed. If the pressing force is insufficient, the triggering member 221 cannot be pressed against the triggering table 11, and the button function cannot be triggered, and an abnormal sound is generated (this condition is called an empty stroke), which may cause the user to be uncomfortable. feel.

Therefore, it is necessary to create a touch sensing device to solve the lack of prior art.

The above and other objects, features and advantages of the present invention will become more apparent and understood.

Please refer to FIG. 2 below, which is a schematic diagram of a touch sensing device according to a first embodiment of the present invention. According to an embodiment of the present invention, the touch sensing device 120 is assembled on the housing 110 of the electronic device, and the housing 110 includes the touch table 111 and the magnetic member 112. The touch sensing device 120 includes a contact layer 121, a circuit board 122, an adhesive layer 123, and a metal layer 124.

According to an embodiment of the present invention, the electronic device is, for example, a notebook computer, and the touch sensing device 120 is, for example, a notebook computer. The key area of the touch panel disposed on the above is only the components associated with the touch sensing device 120 to be clearly recognized by the reader. However, the creation does not limit the form of the electronic device, and any electronic device that needs to be controlled by the touch sensing device can be applied to the embodiment.

In accordance with an embodiment of the present invention, the contact layer 121 is adapted to receive contact with a finger or conductor. The contact layer 121 is generally made of a copper foil material, but the creation is not limited thereto.

According to an embodiment of the present invention, the circuit board 122 is disposed under the contact layer 121, and the circuit board 122 includes the touch member 1221. The position of the touch member 1221 corresponds to the position of the touch table 111. When the user presses the contact layer 121, the contact layer 121 will drive the circuit board 122 to sink. When the touch member 1221 on the lower surface of the circuit board 122 is pressed against the touch pad 111 of the housing 110, the touch member 1221 is thus And trigger. In this way, the touch sensing device 120 can have a pressing function like a conventional physical button.

According to an embodiment of the present invention, the metal layer 124 is disposed under the circuit board 122 and is magnetically coupled to the magnetic member 112. The layer 123 is disposed between the circuit board 122 and the metal layer 124 for fixedly bonding the circuit board 122 to the metal layer 124. According to an embodiment of the present invention, the material of the layer 123 is a polyester film, but the creation is not limited thereto.

According to an embodiment of the present invention, as shown in FIG. 2, when the metal layer 124 is magnetically connected to the magnetic member 112, the distance d between the metal layer 124 and the magnetic member 112 is substantially about 0.5 mm, but this creation does not This is limited. Since the magnetic member 112 magnetically adsorbs the metal layer 124, the strap 1212 keeps contacting the triggering table 111, so that the user only needs to gently press the contact layer 121, so that the trigger member 1221 can be pressed against the triggering table 111 to trigger. Actuating member 1221 without blank lines as described in the prior art Cheng problem. Since the actuating member 1221 is kept in contact with the triggering table 111, the operating pressure of the actuating member 1221 must be adjusted to be slightly larger than the magnetic force of the magnetic member 112 (for example, 100 g to 150 g larger than the magnetic force) to avoid false touch.

Next, please refer to FIG. 3 , which is a schematic diagram of a touch sensing device according to a second embodiment of the present invention. In the second embodiment, most of the components are the same as the previous embodiment, and will not be described in detail in this embodiment. In this embodiment, the touch sensing device 120a is assembled on the housing 110a of the electronic device. The housing 110a includes a touch table 111a and a magnetic member 112a.

The main difference between the second embodiment and the first embodiment is the position of the magnetic member 112a. In the second embodiment, the magnetic member 112a is disposed on the actuation table 111a. The circuit board includes a metal material touch member 1221a. The position of the touch member 1221a corresponds to the position of the magnetic member 112a and is magnetically connected to the magnetic member 112a.

Since the magnetic member 112a magnetically attracts the metal trigger member 1221a such that the trigger member 1221a remains in contact with the actuation table 111a, the user only needs to gently press the contact layer 121a so that the contact force is slightly larger than the magnetic force (for example, the contact force is greater than the magnetic force). With an extra 100g-150g), the actuator 1221a can be triggered without the problem of idle travel as described in the prior art.

In summary, this creation, regardless of its purpose, means and efficacy, is showing its characteristics that are different from the well-known techniques.
