The specific structure of theprocessing unit 14 will be described in detail later.

在本实施例中，多功能背夹装置1利用无线传输单元13与播放装置3实现无线多媒体数据传输。在此，无线传输单元13为WIFI无线传输单元。然而，本发明并不限定于此。在其它实施例中，无线传输单元13也可为蓝牙或红外无线传输单元。In this embodiment, the multifunctionalback clip device 1 utilizes thewireless transmission unit 13 and theplayback device 3 to realize wireless multimedia data transmission. Here, thewireless transmission unit 13 is a WIFI wireless transmission unit. However, the present invention is not limited thereto. In other embodiments, thewireless transmission unit 13 can also be a Bluetooth or an infrared wireless transmission unit.

在本实施例中，多功能背夹装置1利用无线充电单元16与无线充电基座4实现无线充电。如图2所示，无线充电单元16包括充电线圈160、整流器161、电流输出端162以及可充电电池163。其中，整流器161连接充电线圈160、电流输出端162以及可充电电池163。可充电电池163连接处理单元14。电流输出端162可连接手持装置2。然而，本发明并不限定于此。在其它实施例中，无线充电单元16中可不设置可充电电池163，而多功能背夹装置1的电力可直接由电流输出端162提供。In this embodiment, the multi-functionalback clip device 1 utilizes thewireless charging unit 16 and the wireless charging base 4 to realize wireless charging. As shown in FIG. 2 , thewireless charging unit 16 includes a charging coil 160 , arectifier 161 , acurrent output terminal 162 and arechargeable battery 163 . Wherein, therectifier 161 is connected to the charging coil 160 , thecurrent output terminal 162 and therechargeable battery 163 . Arechargeable battery 163 is connected to theprocessing unit 14 . Thecurrent output terminal 162 can be connected to thehandheld device 2 . However, the present invention is not limited thereto. In other embodiments, thewireless charging unit 16 may not be provided with therechargeable battery 163 , and the power of themultifunctional backpack device 1 may be directly provided by thecurrent output terminal 162 .

在本实施例中，具体而言，可充电电池163连接处理单元14与无线传输单元13，从而为多功能背夹装置1提供电力。当多功能背夹装置1与无线充电基座4之间的距离小于预设值时，无线充电单元16产生感应电流。其中，预设值可根据需要设定，本发明对此不作任何限定。在实际应用中，当多功能背夹装置1直接放置于无线充电基座4时，无线充电单元16的充电线圈160与无线充电基座4内部的线圈因感应而彼此磁耦合，从而使充电线圈160产生感应电流。充电线圈160产生的感应电流经由整流器161整流后通过电流输出端162提供给手持装置2，同时，产生的感应电流可为可充电电池163充电。此外，需要注意的是，手持装置2内部可设置可充电电池(图未示)。无线充电单元16的电流输出端162可连接手持装置2的可充电电池，以为其提供充电电流。In this embodiment, specifically, therechargeable battery 163 is connected to theprocessing unit 14 and thewireless transmission unit 13 to provide power for themultifunctional backpack device 1 . When the distance between the multifunctionalback clip device 1 and the wireless charging base 4 is smaller than a preset value, thewireless charging unit 16 generates an induced current. Wherein, the preset value can be set as required, which is not limited in the present invention. In practical application, when the multifunctionalback clip device 1 is directly placed on the wireless charging base 4, the charging coil 160 of thewireless charging unit 16 and the coil inside the wireless charging base 4 are magnetically coupled to each other due to induction, so that the charging coil 160 generates an induced current. The induced current generated by the charging coil 160 is rectified by therectifier 161 and provided to thehandheld device 2 through thecurrent output terminal 162 , and at the same time, the generated induced current can charge therechargeable battery 163 . In addition, it should be noted that a rechargeable battery (not shown) may be provided inside thehandheld device 2 . Thecurrent output terminal 162 of thewireless charging unit 16 can be connected to the rechargeable battery of thehandheld device 2 to provide charging current therefor.

在本实施例中，电流输出端162可为通用串行总线(Universal Serial BUS，USB)接口。然而，本发明并不限定于此。In this embodiment, thecurrent output terminal 162 may be a Universal Serial Bus (Universal Serial BUS, USB) interface. However, the present invention is not limited thereto.

另外，为防止可充电电池163过充，无线充电单元16内部可增设微控制器(图未示)与开关(图未示)。微控制器连接可充电电池163与开关，开关设置于整流器161至可充电电池163的供电路径上。具体而言，微控制器可用于侦测可充电电池163的剩余电量，仅当其剩余电量低于某预设值(例如为95％的电池饱和电量)时，微控制器才控制开关导通，以为可充电电池163充电。反之，当可充电电池163的剩余电量高于预设值时，微控制器控制开关断开，以防止可充电电池163过充而损坏。然而，本发明并不限定于此。In addition, to prevent therechargeable battery 163 from being overcharged, a microcontroller (not shown) and a switch (not shown) can be added inside thewireless charging unit 16 . The microcontroller is connected to therechargeable battery 163 and the switch, and the switch is set on the power supply path from therectifier 161 to therechargeable battery 163 . Specifically, the microcontroller can be used to detect the remaining power of therechargeable battery 163, and only when the remaining power of therechargeable battery 163 is lower than a preset value (for example, 95% of the battery's saturated power), the microcontroller controls the switch to be turned on. , to charge therechargeable battery 163. Conversely, when the remaining power of therechargeable battery 163 is higher than the preset value, the microcontroller controls the switch to be turned off, so as to prevent therechargeable battery 163 from being damaged due to overcharging. However, the present invention is not limited thereto.

图3为本发明的一较佳实施例的多功能背夹装置的局部电路示意图。请参考图2与图3。如图3所示，处理单元14包括多媒体数据编码器140。在此，多媒体数据编码器140为芯片TF630。由于连接接口12自手持装置2接收的多媒体数据D1过大，因此，利用多媒体数据编码器140将多媒体数据D1压缩为压缩数据D2后再进行传输。FIG. 3 is a schematic partial circuit diagram of a multifunctional back clip device according to a preferred embodiment of the present invention. Please refer to Figure 2 and Figure 3. As shown in FIG. 3 , theprocessing unit 14 includes amultimedia data encoder 140 . Here, themultimedia data encoder 140 is a chip TF630. Since the multimedia data D1 received by theconnection interface 12 from thehandheld device 2 is too large, themultimedia data encoder 140 is used to compress the multimedia data D1 into compressed data D2 before transmission.

在本实施例中，如图3所示，芯片EP9853提供高清晰度多媒体接口(HDMI)，且其同多媒体数据编码器140(芯片TF630)相连接。此外，芯片EP9853利用数字-模拟转换器同声卡AC97相连接，且声卡AC97同多媒体数据编码器140相连接。因此，若多媒体数据D1包括声音数据，则声卡AC97可解码多媒体数据D1中的声音数据后再将其传输至多媒体数据编码器140。In this embodiment, as shown in FIG. 3 , the chip EP9853 provides a high-definition multimedia interface (HDMI), and it is connected with the multimedia data encoder 140 (chip TF630). In addition, the chip EP9853 is connected with the sound card AC97 by using a digital-to-analog converter, and the sound card AC97 is connected with themultimedia data encoder 140 . Therefore, if the multimedia data D1 includes audio data, the sound card AC97 can decode the audio data in the multimedia data D1 and then transmit it to themultimedia data encoder 140 .

在本实施例中，多媒体数据编码器140的时钟频率为10MHz，且多媒体数据编码器140还同无线传输单元13相连接、EEPROM、SDRAM、RS232接口、闪存等元件。其中，无线传输单元13可为WIFI无线传输单元。闪存中存储多功能背夹装置1的开机信息以及驱动程序。EEPROM中可存储用于调整影像数据显示质量的相关程序。即，多功能背夹装置1可根据手持装置2的屏幕分辨率来运用EEPROM中储存的相关程序自动调整传输至播放装置3的影像数据，以使播放装置3达到最佳的显示效果。SDRAM可于多媒体数据传输过程中用于暂存数据。多功能背夹装置1利用RS232接口作内部测试除错用(debug)。另外，多媒体数据编码器140还可连接指示元件。指示元件例如可为LED指示灯，用于指示多功能背夹装置1的工作状态。例如，当多功能背夹装置1开启后，指示元件可显示红色。当多功能背夹装置1开始传输多媒体数据时，指示元件可显示绿色。在此，多功能背夹装置1的指示元件利用GPIO实现其色彩变换。然而，本发明并不限定于此。In this embodiment, the clock frequency of themultimedia data encoder 140 is 10MHz, and themultimedia data encoder 140 is also connected with thewireless transmission unit 13, EEPROM, SDRAM, RS232 interface, flash memory and other components. Wherein, thewireless transmission unit 13 may be a WIFI wireless transmission unit. The booting information and the driver of the multifunctionalback clip device 1 are stored in the flash memory. Related programs for adjusting the display quality of image data can be stored in the EEPROM. That is, the multifunctionalback clip device 1 can automatically adjust the image data transmitted to theplayback device 3 according to the screen resolution of thehandheld device 2 by using related programs stored in the EEPROM, so that theplayback device 3 can achieve the best display effect. SDRAM can be used to temporarily store data during multimedia data transmission. The multifunctionalback clip device 1 utilizes the RS232 interface for internal testing and debugging (debug). In addition, themultimedia data encoder 140 can also be connected with a pointing element. The indicating element can be, for example, an LED indicator light, which is used to indicate the working state of the multifunctionalback clip device 1 . For example, when the multifunctionalback clip device 1 is turned on, the indicating element can display red. When the multi-functionback clip device 1 starts to transmit multimedia data, the indicating element can display green. Here, the indicator element of the multi-functionback clip device 1 uses GPIO to realize its color change. However, the present invention is not limited thereto.

综上所述，本发明较佳实施例提供的多功能背夹装置利用连接接口、处理单元、无线传输单元实现多媒体数据的无线传输，利用无线充电单元实现无线充电功能。这样，本发明较佳实施例提供的多功能背夹装置同时具有多媒体数据无线传输功能以及无线充电功能。因此，本发明较佳实施例提供的多功能背夹装置不仅改善了先前技术中背夹装置功能单一的不足，而且方便了手持装置的使用。To sum up, the multifunctional back clip device provided by the preferred embodiment of the present invention uses the connection interface, the processing unit, and the wireless transmission unit to realize wireless transmission of multimedia data, and uses the wireless charging unit to realize the wireless charging function.
