本發明係關於一種可攜式電腦，特別是包含壓電換能模組的可攜式電腦。The invention relates to a portable computer, in particular to a portable computer including a piezoelectric transducer module.

一般來說，可攜式電腦中會設有電池，藉以提供可攜式電腦中的各個電子元件運作所需的電力。Generally speaking, a battery is provided in a portable computer to provide power required for the operation of various electronic components in the portable computer.

然而，可攜式電腦中的電池通常僅能透過外部電源來充電。如此一來，當可攜式電腦中的電池自外部電源斷開時，該可攜式電腦將僅能依主電池供電，該主電池的電量便會因使用狀態而逐步地消耗，進而造成可攜式電腦的續航力不足。However, the battery in a portable computer can usually only be charged by an external power source. In this way, when the battery in the portable computer is disconnected from the external power source, the portable computer will only be powered by the main battery, and the power of the main battery will be gradually consumed due to the state of use, resulting in possible The battery life of the portable computer is insufficient.

本發明在於提供一種可攜式電腦，藉以提供額外的電力來源用以連接外部電源之主電池。The present invention is to provide a portable computer to provide an additional power source for connecting the main battery of an external power source.

本發明之一實施例所揭露之可攜式電腦包含一主機座體、一顯示機體以及一主電池。主機座體包含一座體及設置於座體中的一鍵盤。顯示機體樞接於主機座體。主電池電性連接於鍵盤中。鍵盤包含一基座、多個鍵帽及至少一壓電換能模組。鍵帽設置於基座上。至少一壓電換能模組設置於基座及鍵帽之間。基座設置於座體中，且至少一壓電換能模組電性連接於主電池。A portable computer disclosed in an embodiment of the present invention includes a main body, a display body and a main battery. The base body of the host includes a base body and a keyboard arranged in the base body. The display body is pivotally connected to the host body. The main battery is electrically connected to the keyboard. The keyboard includes a base, a plurality of keycaps and at least one piezoelectric transducer module. The keycap is arranged on the base. At least one piezoelectric transducer module is arranged between the base and the keycap. The base is arranged in the seat body, and at least one piezoelectric transducer module is electrically connected to the main battery.

根據上述實施例所揭露的可攜式電腦，由於壓電換能模組設置於基座及鍵帽之間，且壓電換能模組電性連接於主電池，因此壓電換能模組會收集按壓鍵帽所產生的力學能，並將所收集的力學能轉換成電力訊號來提供給主電池。如此一來，主電池便能從外部電源以外的來源取得電力，進而增加可攜式電腦的續航力。According to the portable computer disclosed in the above-mentioned embodiments, since the piezoelectric transducer module is arranged between the base and the keycap, and the piezoelectric transducer module is electrically connected to the main battery, the piezoelectric transducer module The mechanical energy generated by pressing the keycap is collected, and the collected mechanical energy is converted into an electrical signal to provide to the main battery. In this way, the main battery can draw power from a source other than the external power source, thereby increasing the battery life of the portable computer.

可攜式電腦10例如包含一主機座體100、一顯示機體200、一主電池300、一備用電池400及一控制電路500。The portable computer 10 includes, for example, a main body 100 , a display body 200 , a main battery 300 , a backup battery 400 and a control circuit 500 .

主機座體100例如包含一座體101、鍵盤102及一觸控面板103。鍵盤102及觸控面板103並排地設置於座體101中。鍵盤102包含一基座1020、多個鍵帽1021及一壓電換能模組1022。鍵帽1021設置於基座1020上。壓電換能模組1022設置於基座1020及鍵帽1021之間。基座1020設置於座體101中。The host base 100 includes, for example, a base 101 , a keyboard 102 and a touch panel 103 . The keyboard 102 and the touch panel 103 are arranged side by side in the base body 101 . The keyboard 102 includes a base 1020 , a plurality of keycaps 1021 and a piezoelectric transducer module 1022 . The keycap 1021 is disposed on the base 1020 . The piezoelectric transducer module 1022 is disposed between the base 1020 and the keycap 1021 . The base 1020 is disposed in the seat body 101 .

舉例來說，壓電換能模組1022固定於基座1020，且包含依序堆疊的一撓性基板1023、一第一導電層1024、一壓電材料層1025及一第二導電層1026，並重疊於所有的鍵帽1021。然，本發明並不以壓電換能模組1022固定在基座1020為限；於其他實施例中，壓電換能模組亦可固定於鍵盤的這些鍵帽。For example, the piezoelectric transducer module 1022 is fixed on the base 1020, and includes a flexible substrate 1023, a first conductive layer 1024, a piezoelectric material layer 1025 and a second conductive layer 1026 stacked in sequence, And overlap all the keycaps 1021 . However, the present invention is not limited to the fact that the piezoelectric transducer module 1022 is fixed on the base 1020; in other embodiments, the piezoelectric transducer module can also be fixed on these keycaps of the keyboard.

顯示機體200樞接於主機座體100。The display body 200 is pivotally connected to the main frame body 100 .

主電池300電性連接於鍵盤102之壓電換能模組1022的第一導電層1024、壓電材料層1025及第二導電層1026。此外，主電池300用以連接一外部電源20。The main battery 300 is electrically connected to the first conductive layer 1024 , the piezoelectric material layer 1025 and the second conductive layer 1026 of the piezoelectric transducer module 1022 of the keyboard 102 . In addition, the main battery 300 is used to connect to an external power source 20 .

備用電池400透過控制電路500電性連接於壓電換能模組1022，且主電池300透過控制電路500電性連接於壓電換能模組1022。控制電路500用以根據主電池300是否處於一充電狀態，來決定傳送壓電換能模組1022所產生的電力訊號給備用電池400或主電池300。The backup battery 400 is electrically connected to the piezoelectric transducer module 1022 through the control circuit 500 , and the main battery 300 is electrically connected to the piezoelectric transducer module 1022 through the control circuit 500 . The control circuit 500 is used to determine whether to send the power signal generated by the piezoelectric transducer module 1022 to the backup battery 400 or the main battery 300 according to whether the main battery 300 is in a charging state.

當按壓鍵帽1021所產生的力學能傳遞至壓電換能模組1022時，壓電換能模組1022會將所接收到的力學能轉換成電力訊號；壓電換能模組1022所產生的電力訊號接著會傳送至控制電路500；舉例來說，當主電池300連接外部電源20而處於充電狀態時，控制電路500會傳送壓電換能模組1022所產生的電力訊號給備用電池400；當主電池300無連接外部電源20而處於一放電狀態時，控制電路500會傳送壓電換能模組1022所產生的電力訊號給主電池300，但本發明並不以此為限。When the mechanical energy generated by pressing the keycap 1021 is transmitted to the piezoelectric transducer module 1022, the piezoelectric transducer module 1022 will convert the received mechanical energy into an electrical signal; The power signal will then be transmitted to the control circuit 500; for example, when the main battery 300 is connected to the external power source 20 and is in a charging state, the control circuit 500 will transmit the power signal generated by the piezoelectric transducer module 1022 to the backup battery 400 ; When the main battery 300 is in a discharge state without being connected to the external power source 20, the control circuit 500 will transmit the power signal generated by the piezoelectric transducer module 1022 to the main battery 300, but the present invention is not limited thereto.

然，本發明並不以備用電池400及控制電路500的設置為限；於其他實施例中，可攜式電腦亦可不具有備用電池及控制電路，而無論主電池是否連接外部電源，皆將壓電換能模組所輸出的電力訊號傳送至主電池。However, the present invention is not limited to the arrangement of the backup battery 400 and the control circuit 500; in other embodiments, the portable computer may not have the backup battery and the control circuit, and regardless of whether the main battery is connected to an external power source, the voltage The power signal output by the power conversion module is sent to the main battery.

A simple schematic diagram of a top view of multiple keycaps and multiple piezoelectric transducer modules of a portable computer; in this embodiment, there are multiple piezoelectric transducer modules 1022a. Each of the piezoelectric transducing modules 1022a overlaps with a plurality of keycaps 1021a, and some of the keycaps 1021a do not overlap with any piezoelectric transducing modules 1022a. That is to say, it is also possible to make only the part of the keycap 1021a that is used more frequently overlap with the piezoelectric transducer module 1022a, and make the part of the keycap 1021a that is used less frequently not overlap with any piezoelectric transducer module. Groups 1022a overlap. For example, for an e-sports portable computer, the frequently used part of the keycap 1021a may be the keycap corresponding to the English letter W, A, S or D; In other words, the frequently used part of the keycap 1021a may be the keycap corresponding to the vowel letter A, E, I, O or U.

根據上述實施例所揭露的可攜式電腦，由於壓電換能模組設置於基座及鍵帽之間，且壓電換能模組電性連接於主電池，因此壓電換能模組會收集按壓鍵帽所產生的力學能，並將所收集的力學能轉換成電力訊號來提供給主電池。如此一來，主電池便能從外部電源以外的來源取得電力，進而增加可攜式電腦的續航力。According to the portable computer disclosed in the above-mentioned embodiments, since the piezoelectric transducer module is arranged between the base and the keycap, and the piezoelectric transducer module is electrically connected to the main battery, the piezoelectric transducer module The mechanical energy generated by pressing the keycap is collected, and the collected mechanical energy is converted into an electrical signal to provide to the main battery. In this way, the main battery can draw power from a source other than the external power source, thereby increasing the battery life of the portable computer.
