A kind of rear-mounted touch control device for smart machineTechnical field
The control device of the smart machines such as one is applicable to mobile phone, panel computer
Background technology
Mobile phone, the equipment such as panel computer are generally operated by touch-screen, and this mode of operation, when screen is less, operates more convenient, but when size is larger, just there will be some problems.Such as, cannot one-handed performance, when needs hands grasping, cannot operate.At present, the size of equipment develops increasing, and 5 cun even large-screen mobile phone of 6 cun are very general, the problem of one-handed performance cannot also become more and more outstanding.When hands grasping panel computer, operate its touch-screen also not too convenient.
Summary of the invention
The object of the invention is the problem in order to solve touch screen operation inconvenience, proposing a kind of rear-mounted touch control device.
The present invention can be realized by following technology:
For a rear-mounted touch control device for smart machine, comprise touch pad or touch-screen, control chip and corresponding control software design, is characterized in that: the back side being positioned at smart machine.
The described rear-mounted touch control device for smart machine, is characterized in that: described touch control device is positioned at the inside at the smart machine back side, operates on it across bonnet finger.
The described rear-mounted touch control device for smart machine, it is characterized in that: comprise a switch, when finger contact switch or finger press switch or finger from switch or when streaking above switch, described rear-mounted touch control device is opened, response user operation; When finger leaves switch or finger upspring switch or finger when streaking in the other direction from switch or above switch, described rear-mounted touch control device is closed, and does not respond the operation of user.
The described rear-mounted touch control device for smart machine, is characterized in that: point when to mark a particular track on touch control device, touch control device opens or closes; Or in certain hour, point attonity on touch control device, touch control device is closed.
Touch control device can adopt capacitive type touch pad/screen, and when touch pad/screen is positioned at bonnet inside, finger cannot directly contact, and floating touch technology be used to operate on it.

Comprise and touch circuit (sensor), control chip, control software design.Touch circuit inductance finger signal, control chip and software control touch circuit, chip adopts the Sai Pulasi chip of floating better performances, chip can be positioned on the mainboard of mobile phone, or touch on circuit (sensor), touch circuit (sensor) and be positioned at the back side of mobile phone, the inside of bonnet is near the position of top.In the central authorities position on the upper side of two sides of mobile phone, each installation soft-touch control, soft-touch control has left button function concurrently, when finger contact soft-touch control, Postposition touchpad is opened, and when finger leaves soft-touch control, Postposition touchpad is closed, when finger clicks soft-touch control, be equivalent to click left button.
When user is hold by one hand mobile phone, thumb operation touch-screen, its method of operating is constant.When thumb cannot operate, use Postposition touchpad operating handset, method is: middle finger or the third finger are placed on the soft-touch control of side, and forefinger is placed on the back side, across bonnet operating touchpad.When forefinger moves, cursor of mouse appears in mobile phone screen, and cursor moves along with finger, when cursor moves to target location, click soft-touch control.
Postposition touchpad is supplementing of touch-screen, when touch screen operation inconvenience, can use Postposition touchpad operating handset effectively.Both combine, and can realize the one-handed performance of large-screen mobile phone.
Embodiment 2 is for the Postposition touchpad of panel computer
Touch pad is positioned at the left and right sides at the back side, near hands grasping position.The other the same as in Example 1.
