As shown in Figure 6, mobile terminal main body module and detachable bluetooth keyboard module 102 constitute in the utility model, and use this portable terminal and realize that communication comprises:
Step 601 judges whether described detachable bluetooth keyboard module (being called for short module B) breaks away from mobile terminal main body module (abbreviation modules A), if then change step 602 over to, otherwise change step 605 over to.
Step 602 judges whether the electric weight of detachable bluetooth keyboard module can satisfy application conditions, if can satisfy, then changes step 603 over to, otherwise the step 604 of packing into;
Wherein, the situation of the Bluetooth pairing failure that should under rare occasion, occur, if the Bluetooth pairing failure then points out user's bluetooth to reconnect, the user can manually select to reconnect.
605, modules A and module B communicate by the logistics interface, and the key assignments information that the user that detachable bluetooth keyboard module is received imports sends to the mobile terminal main body module by physical interface.
In order to guarantee the normal operation of detachable bluetooth keyboard module, the utility model embodiment also comprises:
Step 606 is monitored the battery electric quantity of described detachable bluetooth keyboard module, if electric weight is low, then the battery to detachable bluetooth keyboard module charges.
In actual applications, under the mobile terminal standby mode, after bluetooth keyboard B takes off or is placed on A, all can have and interrupt reporting, after interruption reports the bluetooth keyboard status signal, application program is judged the bluetooth keyboard state according to the value of reporting, generally can be divided into two kinds of patterns: bluetooth keyboard takes out, and bluetooth keyboard is put into.
As shown in Figure 7, when bluetooth keyboard module and the disengaging of described mobile terminal main body module, the flow process that the portable terminal that using the utility model provides communicates, step is as follows:
Step 700 is that detachable bluetooth keyboard 101 is disengaged position with described mobile terminal main body module 101 according to judge module B13 judged result, and can establish the bluetooth keyboard mode bit in the utility model embodiment is 1.
Step 701, whether the battery electric quantity that detects in the detachable bluetooth keyboard module can satisfy application conditions, if electric weight is low, then forwards step 705 to; Otherwise forward step 702 to.
Step 702 starts the auxilliary module of bluetooth primary module and bluetooth, and the bluetooth module in the bluetooth keyboard enters mode of operation, and enters step 703.
Step 703, the auxilliary module of bluetooth primary module and bluetooth is matched, if successful matching then enters step 704, enters step 706 otherwise return.
Step 704, this moment, the Keysheet module of bluetooth keyboard was taken over control by the auxilliary module of bluetooth, after key assignments information is handled by bluetooth module, gave the bluetooth primary module by the auxilliary module communication of bluetooth, the bluetooth primary module reports baseband module again, and the user just can be used as remote controller and uses this bluetooth module at this moment.
" * " key on the Keysheet module A15 of mobile terminal main body module can be used as the final election key simultaneously, the key assignments reusable of keyboard is a function key etc., though this moment, detachable bluetooth keyboard module was left the mobile terminal main body module, the mobile terminal main body module still can be used separately.
Step 705, prompting user electric weight is low, detachable bluetooth keyboard module need be adhered to the mobile terminal main body module this moment and charge.In detachable bluetooth keyboard module electric weight deficiency, under the situation about can't use separately, the prompting user needs charging on display module A14.
Step 706, the situation of the Bluetooth pairing that under rare occasion, occurs failure, prompting user bluetooth need reconnect, and the user can manually select to reconnect.
As shown in Figure 8, when the bluetooth keyboard module attached to described mobile terminal main body module on the time use the utility model and realize communication, step is as follows:
Step 800 is detachable bluetooth keyboard 101 and the state of described mobile terminal main body module 101 for adhering to according to judge module B13 judged result, and can establish the bluetooth keyboard mode bit is 0.
Step 803 if electric weight is low, enters step 804, otherwise enters step 802.
Step 804 is charged to the battery of detachable bluetooth keyboard module.
The utility model embodiment discloses a kind of mobile terminal system and implementation method with detachable bluetooth keyboard, detachable bluetooth keyboard is as the part of portable terminal keyboard rather than all among the utility model embodiment, after bluetooth keyboard takes out as independent sector, can communicate by letter with mobile terminal main body, thereby realize that information interaction realizes Remote control by bluetooth approach.Even mobile terminal main body after bluetooth keyboard takes out, also has fixedly keyboard such as numerical key, unsegregated keyboard still can normally use by the button multiplexing mode.Bluetooth keyboard has interface module, after placing mobile terminal main body, bluetooth keyboard closes Bluetooth function automatically, interface module will be connected with mobile terminal physical, guarantee normal use stable and reliable, solved the above-mentioned bluetooth keyboard of issued patents and all separated the information input shortcoming that the speed of response is not high and power consumption is bigger that causes.
The detachable bluetooth keyboard of the utility model embodiment need not the external charge device, has independently power module, and the power management unification is undertaken by mobile terminal main body, guarantees the independent service time of detachable bluetooth keyboard module.Simultaneously detachable bluetooth keyboard have and mobile terminal main body between the charging inlet signal, when electric weight does not satisfy application demand, it is charged, so the inner power management chip that just do not need to increase of bluetooth module by mobile terminal main body.Even bluetooth keyboard electric weight deficiency as long as bluetooth keyboard attached on the mobile terminal main body, connects by physics mode, also can guarantee the normal use of portable terminal basic function.
When portable terminal enters standby mode, even bluetooth module also is in park mode, the keyboard that does not have to separate that is positioned at portable terminal can in time respond practical applications such as incoming call or information, and the user need not wait for.
Therefore the utility model embodiment technical problem to be solved is: overcome in the prior art because the restricted defective of wired mode, overcome the defective of Wireless Keyboard scheme existence in reality realizes of existing document announcement simultaneously, a kind of portable terminal with detachable bluetooth keyboard is provided, thereby realize that wireless remote control uses, even shooting, take pictures and portable terminal method and apparatus that other need Remote to use.And the bluetooth keyboard of the utility model embodiment is compared disclosed mode, and volume is small and exquisite, is convenient to operation, is easier to realize.
Method described in the utility model is not limited to the embodiment described in the embodiment, and those skilled in the art draw other execution mode according to the technical solution of the utility model, belong to technological innovation scope of the present utility model equally.Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
