Specific embodiment
Herein below will be arranged in pairs or groups schema, and technology contents of the present utility model are illustrated by particular specific embodiment, be familiar with
The personage of this technology can easily understand other advantages of the present utility model and effect by content disclosed in the present specification.This reality
Also can be implemented or be applied by other different specific embodiments with new.The various details in this specification can also be based on
Different viewpoints and application, under without departing substantially from spirit of the present utility model, carry out various modifications and change.Especially, in schema
The proportionate relationship and relative position of each element only have exemplary use, not represent the actual state of the utility model implementation.
The utility model provides a kind of Trackpad (touch pad), can be input into the computers such as such as coordinate to portable computer
Control signal, Trackpad (touch pad) of the present utility model can change outward appearance, make the operation shape of Trackpad in operating of contacts
State can be presented by the visual effect for lighting, and use the product competitiveness for improving Trackpad.
For the technological thought of Trackpad of the present utility model, disclosed referring to Fig. 1 to Fig. 7 in the utility model schema
Multiple embodiments illustrate：
Trackpad of the present utility model can be applied into portable computer, to provide the computer control news such as input such as coordinate
Number.
As shown in Figures 1 to 4, Trackpad of the present utility model 1 allows user contact point P optionally thereon to apply
Adjunction touch F.Trackpad of the present utility model 1 includes touch module 11, backlight module 12, elastic layer 13 and protective layer 14.
Touch module 11 can detect contact point P where position.Backlight module 12 has light guide plate 121 with a plurality of light sources 122 (depending on real
Border service condition, if the area of Trackpad 1 is small and light source that used can provide high brightness, being not excluded for backlight module 12 only needs
Single light source 122).Light guide plate 121 is located at the top of touch module 11.A plurality of light sources 122 form a line and are arranged at and lead
At least one side (as shown in fig. 7, a plurality of light sources 122 also may be disposed at the adjacent two sides of light guide plate 121) of tabula rasa 121,
Incided in light guide plate 121 with providing light, recycle the total reflection characteristic of the upper and lower surface of light guide plate 121, incident ray is existed
The expert of light guide plate 121 and then distal end is transferred to by near-end.It should be noted that each light source 122 may be selected to use LED light source.
In the utility model, protective layer 14 is, for example, the mylar film for being arranged at the top of light guide plate 121, is used to light guide plate
121 provide protection, but should be noted that protective layer 14 can be omitted in the case where the strength of materials of light guide plate 121 is enough.
Elastic layer 13 is located at the top of touch module 11, and has overlapping relation with light guide plate 121, as shown in Fig. 2 elastic
The lower section that layer 13 can be stacked at light guide plate 121, i.e. elastic layer 13 are located between touch module 11 and light guide plate plate 121, but not with
This is limited, as shown in figure 5, elastic layer 13 can also be stacked at the top of light guide plate 121.As shown in figures 2 and 5, when user not
When applying contact force F, the protuberance 131 of elastic layer 13 is separated with the holding of light guide plate 121, that is, each protuberance 131 and not in contact with
Light guide plate 121, makes the total reflection characteristic of the upper and lower surface of light guide plate 121 not changed, and allows the light that each light source 122 is provided to exist
Transmission in light guide plate 121.
In the utility model, elastic layer 13 has a plurality of protuberances 131, and each protuberance 131 is convexly equipped in elastic layer 13
Section configuration in face of the one side of light guide plate 121, and each protuberance 131 may be selected by the shape of triangle, waveform or arc
Constituted.As shown in figure 4, the lower position that user applies the contact point P of contact force F covers at least one protuberance 131.When
When contact point P applies contact force F, contact force F can make light guide plate 121 towards elastic layer 13 to user by the power transmission of protective layer 14
Direction distortion, then causes elastic layer 13 to deform, and at least one protuberance 131 for being covered contact point P lower positions is contacted
The regional area on the surface of light guide plate 121, to destroy the total reflection characteristic of the touched regional area of light guide plate 121, and allows leaded light
The some light of the inside of plate 121 conduction is scattered upwards from the regional area so that contact point P positions light, therefore this reality
Mode of operation can be presented by the visual effect for lighting with new Trackpad 1.
It should be noted that if elastic layer 13 is arranged at the top of light guide plate 121 as shown in Figure 5, elastic layer 13 may be selected
It is made up of light-transmitting materials, the light inside light guide plate 121 is penetrated elastic layer 13, and allows the position of contact point P to light.
In the embodiment shown in Fig. 5, when user applies contact force in contact point, contact force can make by the power transmission of protective layer 14
Elastic layer 13 contacts at least one protuberance 131 that contact point lower position is covered towards the Direction distortion of light guide plate 121
The regional area on the surface of light guide plate 121, to destroy the total reflection characteristic of the touched regional area of light guide plate 121 so that contact
Point position lights.
Furthermore, each light source 122 is arranged at one side of the light guide plate 121 near user, and the light guide plate 121 is close to and uses
When the one side of person refers to that light guide plate 121 is close to user's operation Trackpad, the one of closest user's body position
Side；If by taking notebook computer as an example, i.e., light guide plate 121 is arranged at note-book type computer casing lower section, and each light source 122 is arranged at
Light guide plate 121 user cannot look at straight and is directly sent by each light source 122 near the one side of user's body position
Light, and the luminous visual effect of Trackpad of the present utility model 1 can be avoided, do not emitted beam directly by each light source 122
Interference.
In addition, each light source 122 can respectively send the light of different colours, so when user applies in different contact point P
During adjunction touch F, the position of different contact point P can send the light of different colours so that the utility model Trackpad is sent out
The visual effect of light is more dazzled beautiful.
Above-described embodiment only illustrative principle of the present utility model and effect, not for limitation the utility model.
Any one skilled in the art can repair under without prejudice to spirit and scope of the present utility model to above-described embodiment
Decorations and change.Therefore, rights protection scope of the present utility model, should be as listed by present utility model application the scope of the claims.
