Wherein, the middle plate and the bottom plate are made of 304 stainless steels, the middle plate and the bottom plate stake-fastening, the PCBA board
Fitting is fixed on the top of the middle plate, and the surface substrate fitting is fixed on the surface of the PCBA board.
Further, the middle plate is made of 304 stainless steels of 0.3mm, and the bottom plate is 304 stainless using 0.5mm's
Steel is made, the computer touchpad with a thickness of 2.9 ~ 3.6mm.
Further, the surface substrate is glass substrate or mylar film.
Particularly, the present invention also provides a kind of new structural processing method of laptop touchpad, notebook electricity
Brain Trackpad new structure includes the surface substrate for being successively bonded setting from top to bottom, PCBA board, middle plate and bottom plate, the middle plate
It is made with the bottom plate of 304 stainless steels, procedure of processing are as follows:
Step 1: middle plate and bottom plate are subjected to riveted using technique for riveting；
Step 2: PCBA board is bonded fixation with the surface substrate；
Step 3: the upper surface of middle plate described in the lower surface rain by the PCBA board, which attaches, to be fixed.
Further, the middle plate is made of 304 stainless steels of 0.3mm, and the bottom plate is 304 stainless using 0.5mm's
Steel is made, the computer touchpad with a thickness of 2.9 ~ 3.6mm.
Further, the surface substrate is glass substrate or mylar film.
Compared with prior art, the present invention has the advantages that
In the new structure of laptop touchpad of the invention, plate in the plastic parts in existing touch pad structure is eliminated,
Use middle plate made by only 304 stainless steel materials of 0.3 mm thickness instead, and the baseboard material in original structure is constant but ties
Structure changes, and still uses 304 stainless steel materials of 0.5mm.It is targeted to adopt the technology that ironware meanwhile in its processing technology
Middle plate carries out riveted with technique for riveting with ironware bottom plate, cancels being located in plastic parts between plate and bottom plate in former touch pad structure
Balance bar structure, in this way, technique is simplified, while improving processing efficiency, additionally it is possible to the thickness of Trackpad is effectively reduced, it is full
The lightening growth requirement of sufficient laptop.
Detailed description of the invention
Some specific embodiments of the present invention is described in detail by way of example and not limitation with reference to the accompanying drawings hereinafter.
Identical appended drawing reference denotes same or similar part or part in attached drawing.It should be appreciated by those skilled in the art that these
What attached drawing was not necessarily drawn to scale.In attached drawing:

Fig. 2 is the right side view of laptop touchpad shown in Fig. 1；
Fig. 3 is the partial structurtes enlarged drawing in laptop touchpad right view shown in Fig. 1, for showing its layer structure.
Wherein, the reference numerals are as follows:
1, middle plate, 2, bottom plate, 3, PCBA board, 4, surface substrate.
Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill
Personnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", "vertical",
The orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" be based on the orientation or positional relationship shown in the drawings, merely to
Convenient for description the present invention and simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation,
It is constructed and operated in a specific orientation, therefore is not considered as limiting the invention.In addition, term " first ", " second ",
" third " is used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
As long as in addition, the non-structure each other of technical characteristic involved in invention described below different embodiments
It can be combined with each other at conflict.
Present embodiment describes a kind of laptop touchpad new structures, as shown in Figure 1 to Figure 3, generally
It may include middle plate 1, bottom plate 2, PCBA board 3 and surface substrate 4, wherein the middle plate 1 and the bottom plate 2 are 304 stainless steels
At 2 stake-fastening of the middle plate 1 and the bottom plate, the PCBA board 3 is bonded the top for being fixed on the middle plate 1, the surface
Substrate 4 is bonded the surface for being fixed on the PCBA board 3.
Further, 304 stainless steels of the use of middle plate 1 0.3mm are made, and the 304 of the use of bottom plate 2 0.5mm are not
Rust steel is made.
The surface substrate 4 can carry out selection adjustment according to user demand, and glass substrate or mylar film usually can be used.
The thickness thinnest part of this computer touchpad is 2.9mm, and is provided with the maximum of the thickness at elastic foot, is also only 3.6mm.
Trackpad new structure of the invention, when it is assembled, technique is also more simple, only need to be first by middle plate 1
Punch riveting is carried out with bottom plate 2, the lower surface of surface substrate 4 and the upper surface of PCBA board 3 fit, finally again by PCBA board 3
Lower surface be bonded fixation with the surface of middle plate 1, can be completed the assembling of Trackpad, entire assembling process is taken down notes compared with traditional structure
This computer touchpad, which has, to be significantly improved, and assembly is time-consuming short, and structural member eliminates balancing pole etc., more carries out proposing positive assembly
High product yields.
To sum up, in the new structure of laptop touchpad of the invention, the modeling in existing touch pad structure is eliminated
