Description

TECHNICAL FIELD

[0001] The present application relates to the field of input devices, and more particularly to an input device with touch control function. BACKGROUND

[0002] With the rapid development of technology, the booming of electronic devices brings much convenience to human life. Therefore, how to make the operation of electronic devices more humanized is an important issue. For example, the electronic devices commonly used in daily life are notebook computers, mobile phones, satellite navigation devices, etc. Due to the significant improvement of storage capacity and processor operation performance of the electronic devices, the functions of the electronic devices become increasingly powerful and complex. In order to efficiently operate the electronic devices, the manufacturers of the electronic devices use touchpads as input devices to control the electronic devices.

[0003] Referring to Figure 1 , which is a structural schematic diagram of a notebook computer and its touchpad module. The touchpad module 1 is disposed in the housing 21 of the notebook computer 2 and at least partially exposed for a user to contact and operate the notebook computer 2. For example, the user can contact the touchpad module 1 with a finger and slide on the touchpad module 1 to move the cursor 23 on the screen 22, or press the touchpad module 1 to make the notebook computer 2 execute a specific function. Therefore, the touchpad module 1 can replace the function of a mouse, so that the user does not need to carry or install a mouse, which is inconvenient.

[0004] Referring to Figures 2-3 , Figure 2 , which is a conceptual schematic diagram of the touchpad module shown in Figure 1 when not pressed, Figure 3 , which is a conceptual schematic diagram of the touchpad module shown in Figure 2 after being pressed. The housing 21 of the notebook computer 2 has an inwardly recessed frame 24, and the touchpad module 1 is disposed in the frame 24. The touchpad module 1 includes support structures 11 and trigger portions 12 disposed on opposite sides of the frame 24, and a touch plate 13. The touch plate 13 of the touchpad module 1 is connected to the support structures 11, so that the touch plate 13 of the touchpad module 1 can swing relative to the trigger portions 12 with the support structures 11 as the fulcrum. In addition, the touchpad module 1 includes switches 14 located below the touch plate 13 and corresponding to the trigger portions 12.

[0005] Furthermore, when the user presses the touchpad 13, the touchpad 13 swings downward relative to the trigger portion 12 with the support structure 11 as the fulcrum until the switch 14 of the touchpad module 1 abuts against the trigger portion 12 on the frame 24, so that the switch 14 is triggered to output a switch signal to the notebook computer 2, thereby causing the notebook computer 2 to perform a corresponding function. When the user no longer presses the touchpad 13, the touchpad 13 swings upward relative to the trigger portion 12 according to the elastic force of the support structure 11, so that the touchpad 13 returns to the original position.

[0006] However, the main pressing function of the touchpad module 1 is related to the surface material (such as glass) of the touchpad 13 and the overall rigidity of the printed circuit board. However, with the trend of the notebook computer 2 becoming lighter and thinner, the surface material of the touchpad 13 will use a thin material to replace glass, and the thickness of the printed circuit board will also be relatively thin. In this case, according to the current architecture of the touchpad module 1, that is, the support structure 11 is mainly connected to the upper and lower parts by iron or plastic structure (such as sponge), and the deformation of the iron or plastic structure allows the touchpad 13 to swing up and down. If the touchpad 13 is made of a thin material, it will inevitably cause the overall rigidity of the touchpad 13 to be insufficient and affect the pressing function. Therefore, how to improve the above problems is the focus of attention for relevant personnel in the field. SUMMARY

It should be noted that the recessed portion 314 is formed by bending the first substrate 31, and the barrier 324 is also formed by bending the second substrate 32. The purpose of the recessed portion 314 and the barrier 324 is to increase the structural strength of the first substrate 31 and the second substrate 32, thereby significantly improving the overall structural strength of the touchpad module 3.

[0087] like Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, the third stop portion 321 and the fourth stop portion 322 of the second substrate 32 are respectively connected to one end of the baffle wall 324, and the baffle wall 324 extends toward the first direction D1 close to the first substrate 31.

[0089] The actuation mode of the touchpad module 3 of the present embodiment will be further described below.

[0090] Please refer to Figure 11 and Figure 12 , Figure 11 is a structure schematic diagram of the touchpad module of the present embodiment before pressing. Figure 12 is a structure schematic diagram of the touchpad module of the present embodiment after pressing. It should be particularly pointed out that, in order to more clearly express the actuation relationship of each element of the touchpad module before and after pressing, Figure 11 and Figure 12 The first elastic element 33 and the second elastic element 34 shown in

[0091] As shown in Figure 11 and Figure 12 When the first region R1 of the touch plate 30 is pressed according to the touch of external force, the touch plate 30 swings towards the first substrate 31 with the engaging position of the second stop portion 312 and the fourth stop portion 322 as the fulcrum, so that the switch 300 contacts the trigger portion 310 (as shown in Figure 6 At this time, the touch plate 30 will simultaneously drive the second substrate 32 to swing towards the first substrate 31, and in the process of swinging of the second substrate 32, the second substrate 32 presses the first elastic element 33 to make the first elastic element 33 deform (as shown in Figure 6 , Figure 7 , Figure 10The inclined portion C3 is deformed, and at the same time, the third stop portion 321 of the second substrate 32 is disengaged from the engagement with the first stop portion 311 of the first substrate 31.
