[0027] The present utility model will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Refer to Figure 1 And Figure 2 An embodiment of the full-area equalizing control board device of the present utility model includes a bottom plate 10, a touch unit 20, an elastic unit 30, a backing plate 40, a pressing member 50, a supporting unit 60 and several adhesives 70.

[0029] The bottom plate 10 is made of a metal material into a rectangular plate shape, and includes a bottom periphery 11 and several locking holes 12. By screwing several screws (not shown in the figure) into the locking holes 12, the bottom plate 10 can be fixed to the housing of a notebook computer (not shown in the figure).

[0030] The touch unit 20 is disposed above the bottom plate 10 along an axis L, and includes a touchpad 21, a circuit board 22 connected to the bottom of the touchpad 21, and a pressing switch 23 disposed at the middle part of the bottom of the circuit board 22.

[0031] With reference to Figure 3 The elastic unit 30 is disposed between the bottom plate 10 and the circuit board 22, and includes a positioning area 31 connected to the bottom plate 10 through an adhesive 70, an upper periphery 32 surrounding the periphery of the positioning area 31, a connecting frame group 33 disposed between the positioning area 31 and the upper periphery 32, and a slotted area 34 between the upper periphery 32 and the positioning area 31. In this embodiment, the elastic unit 30 is selected from any one of plastic, metal, glass fiber or carbon fiber, and preferably plastic material is used.

[0032] The upper periphery 32 has two first side edges 321 extending along a transverse axis X, and two second side edges 322 extending along a longitudinal axis Y perpendicular to the transverse axis X and intersecting and connecting to the first side edges 321.

[0033] The connecting frame group 33 is in a ring frame shape and is connected to the backing plate 40 through a rectangular frame-shaped adhesive 70, and the backing plate 40 is further connected to the bottom surface of the circuit board 22 through another rectangular frame-shaped adhesive 70. The connecting frame group 33 has two first frame bars 331 respectively adjacent to the first side edges 321 and extending along the transverse axis X, and two second frame bars 332 respectively adjacent to the second side edges 322 and extending along the longitudinal axis Y, and the second frame bars 332 intersect and connect to the first frame bars 331.

[0034] The setting range of the slotted area 34 is larger than the contour range of the bottom peripheral edge 11, and the slotted area 34 surrounds the periphery of the positioning area 31. The slotted area 34 has two outer transverse slot groups 341 respectively arranged on the first frame bar 331 and located inside the first side edge 321, two inner transverse slot groups 342 respectively located inside the outer transverse slot groups 341, and two longitudinal slot groups 343 respectively located between the second frame bar 332 and the positioning area 31. Each outer transverse slot group 341 has an outer transverse slot 341' extending along the transverse axis X. Each outer transverse slot 341' has two first outer ends 344 adjacent to the second frame bar 332, and each outer transverse slot 341' communicates from one first outer end 344 to the other first outer end 344. Each inner transverse slot group 342 has several inner transverse slots 342' arranged at intervals along the transverse axis X. An interval section 346 connected to the positioning area 31 is formed between two adjacent inner transverse slots 342' arranged along the transverse axis X. The width and thickness of the interval section 346 can be made into different sizes according to the usage requirements. The width direction of the interval section 346 corresponds to the transverse axis X. The magnitude of the downward pressure can be controlled by modifying the width and thickness of the interval section 346. Each longitudinal slot group 343 has a longitudinal slot 343' extending along the longitudinal axis Y. Each longitudinal slot 343' communicates with the corresponding two inner transverse slots 342'.

[0035] And each first frame bar 331 has an outer elastic arm 333 located between the corresponding first side edge 321 and the corresponding outer transverse slot group 341, and an inner elastic arm 334 located between the corresponding outer transverse slot group 341 and the corresponding inner transverse slot group 342. The magnitude of the downward pressure can be controlled by modifying the width and thickness of the outer elastic arm 333. The width direction of the outer elastic arm 333 corresponds to the longitudinal axis Y.

[0036] The positioning area 31 is located inside the inner transverse slot group 342 and the longitudinal slot group 343. In this embodiment, each first side edge 321 is provided with an outer transverse slot group 341 and an inner transverse slot group 342 inside. However, in fact, the number of the outer transverse slot groups 341 or the inner transverse slot groups 342 inside each first side edge 321 can be more than one (not shown in the figure).

[0037] The backing plate 40 is arranged between the circuit board 22 and the elastic unit 30, and includes a positioning frame 41 clamped between the circuit board 22 and the connection frame group 33, and several abutting pieces 42 connected to the positioning frame 41 and abutting against the corresponding inner elastic arms 334 (see Figure 6 ).

[0038] The pressing member 50 is arranged at the middle part of the positioning area 31 of the elastic unit 30 and corresponds to the push button switch 23.

[0039] Cooperating parameters Figures 4 to 6 , the support unit 60 is in a ring frame shape and is connected to the bottom surface of the elastic unit 30 through another adhesive 70 and is positioned relative to the circuit board 22. The support unit 60 includes a fixed frame group 61 connected to the connection frame group 33, and several support pieces 62 connected to the fixed frame group 61 and spanning the corresponding slotted areas 34. The fixed frame group 61 has a pair of transverse frame plates 611 extending along the transverse axis X and respectively fixed to the bottom surfaces of the outer elastic arms 333, and a pair of longitudinal frame plates 612 extending along the longitudinal axis Y and respectively fixed to the bottom surfaces of the second frame rods 332. In this embodiment, the transverse frame plates 611 and the longitudinal frame plates 612 are not connected to each other, and the support pieces 62 are respectively connected to the transverse frame plates 611 and the longitudinal frame plates 612. However, in fact, the fixed frame group 61 can be made into an integral closed ring shape, and the transverse frame plates 611 and the longitudinal frame plates 612 are connected to each other. The non-connection between the transverse frame plates 611 and the longitudinal frame plates 612 can reduce the generation of waste materials.

[0040] The support piece 62 extends from the outer elastic arm 333 towards the corresponding inner elastic arm 334 and spans the corresponding outer transverse groove group 341. The support piece 62 also extends from the second frame rod 332 towards the positioning area 31 and spans the corresponding longitudinal groove group 343 (see Figures 7 to 10 ).

[0041] To further understand the functions, technical means, and expected effects generated by the cooperation of the components of the present invention, the following will be further described. It is believed that a more in-depth and specific understanding of the present invention can be obtained therefrom.

[0042] Refer to Figure 1 , Figures 4 to 10 , when the touch panel device is assembled as a whole, the touch control unit 20 is provided with an upward elastic force by the elastic unit 30, and the first frame rod 331, the second frame rod 332, and the positioning area 31 are kept at the same horizontal height (see Figure 8 and Figure 10 ). At this time, the touch control unit 20 is located at an initial position, the push switch 23 has not been triggered and no signal is generated. Among them, the end of the support piece 62 supports on the bottom surface of the positioning area 31 (see Figure 8 ), and the end of the support piece 62 also supports on the bottom surface of the corresponding inner elastic arm 334 (see Figure 10 ).

[0043] See Figure 11As shown by the arrow, when a force is applied to press one of the side edges or one of the circumferential angles of the touchpad 21 towards the bottom plate 10, the touchpad 21 undergoes unilateral tilting or skew. One of the side edges or one of the circumferential angles of the touchpad 21 corresponding to the pressed part will drive the end of the corresponding support piece 62 away from the bottom surface of the positioning area 31, and the ends of the remaining support pieces 62 are supported on the bottom surface of the positioning area 31. And it can be understood that the end of the support piece 62 corresponding to the pressed part will also be away from the bottom surface of the corresponding inner elastic arm 334( Figure 11 not shown in). And through the setting of the slotted area 34, the connection frame group 33 can be elastically deflected up and down relative to the positioning area 31. At this time, when the pressing switch 23 moves relative to the bottom plate 10 along with the circuit board 22, it is pushed by the contact member 50 and triggered to generate a signal. When the pressing force is released, by using the elastic force provided by the elastic unit 30, the touchpad 21 and the support piece 62 can be restored to Figure 7 , Figure 8 and Figure 9 , Figure 10 the state of.

[0044] See Figure 12 As shown by the arrow, when a force is applied to press the central part of the touchpad 21 towards the bottom plate 10, the touchpad 21 moves downward as a whole and will drive the ends of the support pieces 62 away from the bottom surface of the positioning area 31. And it can be understood that the ends of the support pieces 62 will also be away from the bottom surface of the corresponding inner elastic arm 334( Figure 12 not shown in). And through the setting of the slotted area 34, the connection frame group 33 can be elastically deflected relative to the positioning area 31. At this time, when the pressing switch 23 moves relative to the bottom plate 10 along with the circuit board 22, it is also pushed by the contact member 50 and triggered to generate a signal. When the pressing force is released, by using the elastic force provided by the elastic unit 30, the touchpad 21 and the support piece 62 can be restored to Figure 7 , Figure 8 and Figure 9 , Figure 10 the state of.

[0045] Therefore, the functions that the present utility model can produce can be summarized as follows:

[0046] 1. Except that the bottom plate 10 of the present utility model is made of a metal plate, the rest of the components can use light materials (such as stainless steel sheets, glass fiber, carbon fiber, various plastics), and the components are combined by gluing. The overall weight is much less than that of the products in which most of the existing components are made of metal, and the weight of the above light materials is about 20% of the weight of the metal material.

[0047] 2. The touch unit 20 itself has a certain structural strength and will not be deformed due to the structural relationship between the elastic unit 30 and other components, making it impossible to be pressed.

[0048] 3. The shapes and structures of the elastic unit 30, the back plate 40, and the support unit 60 are quite simple and easy to manufacture, and the overall manufacturing cost can also be reduced.

[0049] 4. By modifying the width and thickness of the spacer section 346 of the elastic unit 30, the magnitude of the downward pressure can be controlled. The magnitude of the downward pressure can also be controlled by modifying the width and thickness of the outer elastic arm 333. The manufacturing dimensions can be adjusted according to different usage requirements.

[0050] In summary, for the all-region uniform pressure control plate device of the present utility model, the overall structure is simple and easy to manufacture and assemble, and it can indeed achieve the purpose of the present utility model.
