Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Referring to fig. 2, 3 and 4, an embodiment of the touch panel device of the present invention includes a touch substrate 1, a circuit module 2, a pivot 3, and a frame 4.
Defining a front-rear axial direction D1, a left-right axial direction D2 perpendicular to the front-rear axial direction D1, and a pressing axial direction D3 perpendicular to both the front-rear axial direction D1 and the left-right axial direction D2. The touch substrate 1, the circuit module 2, the pivot 3 and the frame 4 are arranged along the pressing axis D3.
Referring to fig. 3, 4 and 5, the touch substrate 1 includes a touch surface 11 for touch control. The circuit module 2 includes a circuit substrate 21 connected to the touch substrate 1 and located on a side opposite to the touch surface 11 along the pressing axis D3, a pressing switch 22 provided on the circuit substrate 21 and protruding from the circuit substrate 21 toward a side opposite to the touch substrate 1, and six ground electrodes 23.
The circuit substrate 21 has a first surface 211 on the opposite side to the touch substrate 1 and parallel to the front-rear axial direction D1. The first surface 211 has a suspension area 212 disposed on the front side for the push switch 22 to be disposed, and a pivot area 213 disposed on the rear side. The ground electrode 23 is disposed in the pivot region 213. In the present embodiment, the circuit module 2 includes six ground electrodes 23, but this is merely an example. The circuit module 2 may also include one, two, three, four, five or more than seven ground electrodes 23, which should not be limited thereto.
The pivot 3 is made of metal and includes a fixing portion 31 fixed to the pivot area 213, and three elastic arms 32 connected to the fixing portion 31. In this embodiment, the fixing portion 31 is fixed to the pivot area 213 by welding and electrically connected to the ground electrode 23. However, this fixing method is only for example and should not be limited thereto.
Referring to fig. 6, each elastic arm 32 has a first extension 321 extending from the fixing portion 31 toward a side opposite to the circuit board 21, a second extension 322 extending from the first extension 321 forward, a third extension 323 extending from the second extension 322 toward the circuit board 21, and a guiding section 324 extending from the third extension 323 forward and obliquely toward a side opposite to the circuit board 21. The first extension 321, the second extension 322 and the third extension 323 together define a fitting slot 325 with an opening facing the circuit substrate 21. The third extension 323 and the circuit board 21 define an assembling gap S therebetween.
In this embodiment, the three elastic arms 32 of the pivot 3 are arranged at equal intervals along the left-right axial direction D2. However, the pivotal connection 3 may also include one, two or more than four elastic arms 32, which are not limited to the equally spaced arrangement.
Referring to fig. 3, 4 and 6, the frame 4 is formed in a surrounding shape and is spaced apart from the circuit substrate 21 and made of metal. The frame 4 includes a front frame portion 41 corresponding to the suspension area 212, a rear frame portion 42 corresponding to the pivot area 213, two side frame portions 43 connected between the front frame portion 41 and the rear frame portion 42, and a fitting portion 44 connected to the rear frame portion 42 and embossed on a side of the rear frame portion 42 adjacent to the pivot member 3. The engaging portion 44 has three through slots 441 for the first extension 321 of the elastic arm 32 to pass through, and three engaging blocks 442 respectively adjacent to the front sides of the through slots 441 and respectively engaged with the engaging slots 325. The frame 4 is electrically connected to the pivot 3 through the engaging portion 44.
The engaging block 442 defines an engaging thickness T1 along the pressing axis D3. The second extension 322 defines a moving distance T2 with the circuit substrate 21. The embedded thickness T1 is smaller than the moving distance T2.
In the present embodiment, the number of the through slots 441 and the engaging blocks 442 is designed to match the elastic arm 32. However, for example only, the number of the through slots 441 and the engaging blocks 442 may be one, two or more than four, which should not be limited thereto.
When the user presses the touch surface 11 along the pressing direction D3, the circuit module 2 moves from a default position to a pressing position relative to the frame 4.
In the default position (as shown in fig. 6), the suspension area 212 of the circuit module 2 is away from the front frame portion 41 of the frame 4 without touching the push switch. It should be noted that the elastic arm 32 is not deformed at this time and the engaging block 442 is firmly engaged in the engaging groove 325.
In the pressing position (as shown in fig. 7), the suspension area 212 of the circuit module 2 is adjacent to the front frame 41 of the frame 4 and touches the pressing switch 22, thereby achieving the function of detecting the pressing action. At this time, since the engagement thickness T1 is smaller than the moving distance T2, the elastic arm 32 is slightly deformed and the engagement block 442 is slightly deviated from the engagement groove 325. When the pressing force is released, the elastic arm 32 returns to its original state due to its own elasticity, and the fitting block 442 is again firmly fitted into the fitting groove 325, so that the circuit module 2 returns to the default position.
Because the pivot member 3 is made of metal, the foam sheet has better stability than the foam sheet described in the prior art. In addition, the frame 4 can be electrically connected with the ground electrode 23 indirectly, so that the frame 4, the pivot member 3 and the ground electrode 23 are all electrically neutral. The frame 4 is in a surrounding shape, so that electromagnetic interference (ElectromagneticInterference, EMI) can be effectively prevented after the grounding.
When assembling, the elastic arm 32 is first placed in the through slot 441, and then the frame 4 is pushed along the front-rear axial direction D1, so that the engaging blocks 442 are engaged with the engaging slots 325 along the guide sections 324 through the assembling gap S. Thus, the assembly can be easily performed without additional materials or tools.
In summary, the touch panel device of the present invention improves the stability by the pivot member 3 made of metal, and the fitting block 442 is fitted into the fitting groove 325 to achieve the effect of easy assembly, so that the object of the present invention can be achieved.
