[0028] This utility model provides a touchpad 33 mechanism. Please refer to [link / reference]. Figure 1 and Figure 2 The touchpad mechanism 100 includes a housing 1, a support member 2, and a touch component 3. The support member 2 is disposed on the housing 1. The touch component 3 is connected to the support member 2 and the housing 1, and is used for touch and press by the user.

[0029] For housing 1 mentioned above, please refer to Figure 2 The housing 1 includes an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 are connected and fixed. The upper housing 11 is provided with a receiving groove 111, a first opening 112, a groove 113, a protrusion 114, and a second positioning post 115. The receiving groove 111 accommodates the touch component 3. The first opening 112 is located at the bottom of the receiving groove 111, and the first opening 112 communicates with the receiving groove 111, dividing the bottom of the receiving groove 111 into a first bottom 1111 and a second bottom 1112. The groove 113 is formed by recessing the second bottom 1112. The protrusion 114 is fixed to the bottom of the groove 113 or the side wall of the groove 113, and the protrusion 114 is used to press the touch component 3 to trigger the touch component 3. The second positioning post 115 is fixed to the first bottom 1111 and is inserted into the touch component 3.

[0030] The second positioning post 115 has a second guide part 1151 at the end away from the bottom of the first groove 1111. The second guide part 1151 is used to guide.

[0031] For support member 2 mentioned above, please refer to Figure 2 The support member 2 includes a connecting plate 21 and a support plate 22. The connecting plate 21 is connected to the housing 1 and fixed to the support plate 22. The support plate 22 is located in the first opening 112, close to the bottom of the second groove 1112, protruding from the bottom of the second groove 1112, and fixed to the touch component 3.

[0032] In some embodiments, the support member 2 has deformability. Furthermore, in some embodiments, the support member 2 is integrally made of plastic, giving it the ability to be shaped and deformed.

[0033] In some embodiments, please refer to Figure 3To reduce space occupation, the housing 1 is provided with a mounting groove 116, which is connected to the first opening 112, and the connecting plate 21 is inserted into the mounting groove 116.

[0034] The support plate 22 is provided with a second opening 221, a spring arm 222, and a first positioning post 223. The spring arm 222 extends from the first sidewall of the second opening 221, and there are gaps between the spring arm 222 and the second, third, and fourth sidewalls of the second opening 221, thereby providing space for the spring arm 222 to deform. The first positioning post 223 is fixed to the spring arm 222 and is inserted into the touch component 3. The touch component 3 is positioned by the first positioning post 223 and the second positioning post 115, reducing the possibility of the touch component 3 scraping against the sidewall of the receiving groove 111.

[0035] The first positioning post 223 has a first guide part 2231 at the end away from the support plate 22, and the first guide part 2231 is used to guide.

[0036] In some embodiments, the plane containing the first groove bottom 1111 is the first plane, and the plane containing the surface where the support member 2 is fixed to the touch component 3 is the second plane. The second plane is coplanar with the first plane, making the touch component 3 flat and aesthetically pleasing. Of course, in some embodiments, the second plane is located above or below the first plane, so that the support plate 22 protrudes from the first groove bottom 1111, or the first groove bottom 1111 protrudes from the support plate 22.

[0037] For the aforementioned touch component 3, please refer to Figure 4 The touch component 3 includes a control board 31, a connecting layer 32, and a touch panel 33. The control board 31 is fixed to the support plate 22 and the bottom of the first groove 1111. The control board 31, the connecting layer 32, and the touch panel 33 are stacked and fixed in sequence.

[0038] The control board 31 is provided with a trigger key 311, a first positioning hole 312, and a second positioning hole 313. The trigger key 311 is opposite to the protrusion 114. Under the action of external force, pressing the side of the touch panel 33 opposite to the second groove bottom 1112 causes the trigger key 311 to be triggered by squeezing the protrusion. The first positioning hole 312 is for the insertion of the first positioning post 223. The second positioning hole 313 is for the insertion of the second positioning post 115. The spring arm 222 helps to avoid assembly difficulties caused by manufacturing errors in the control board 31 and / or support plate 22.

[0039] In some embodiments, the control board 31 is fixed to the support plate 22 and the first groove bottom 1111 by adhesive bonding.

[0040] In some embodiments, the connecting layer 32 is fixed to the control panel 31 and the touch panel 33 by means of adhesive.

[0041] It is understood that in some embodiments, the touch component 3 is not limited to the structure described above, and the touch component 3 can be other structures. For example, the touch component 3 does not include the touchpad 33 described above. The touch component 3 includes a touch shell, a control board 31 and a connecting layer 32, both of which are fixed inside the touch shell. The trigger button 311 of the control board 31 extends out of the touch shell. One surface of the connecting layer 32 is fixed to the inner wall of the touch shell, and the other surface of the connecting layer 32 opposite to the first surface is fixed to the control board 31.

[0042] In this embodiment of the present invention, the touch panel mechanism 100 includes a housing 1, a support member 2, and a touch component 3. The housing 1 is provided with a receiving groove 111 and a first opening 112. The first opening 112 is located at the bottom of the receiving groove 111 and communicates with the receiving groove 111. The support member 2 is connected to the housing 1 and is located at the first opening 112. The support member 2 protrudes from the bottom of the receiving groove 111. The touch component 3 is received in the receiving groove 111 and fixed to the support member 2 and the bottom of the first groove 1111. A trigger button 311 is provided on the side of the touch component 3 away from the bottom of the first groove 1111. The trigger button 311 is opposite to the bottom of the second groove 1112. Under the action of external force, pressing the side of the touch component 3 opposite to the bottom of the second groove 1112 will cause the trigger button 311 to squeeze the bottom of the second groove 1112 and be triggered. Since the touchpad mechanism 100 includes a housing 1, a support 2 and a touch component 3, the structure of the touchpad mechanism 100 is simplified and the manufacturing cost of the touchpad mechanism 100 is reduced.

[0043] This utility model also provides a terminal embodiment, the terminal including the touch panel mechanism 100 described above. The structure and function of the touch panel mechanism 100 can be referred to the above embodiment, and will not be repeated here.
