五、 [0001] [0002] 新型說明: 【新型所屬之技術領域】 本創作係有關於—種充電裝置,特別是指一種無線 充電裝置。 【先前技術】 在現今科技發達的年代,人類脫離不了電氣用品之 使用,例如:家電用品、電腦、照明設備等,無一不是須 使用電源來運作’電源係由電力公司透過各種發電方式, 經由輸配線系統來供應,而發電方式依據電力產生方式 的不同可分為火力發電、水力發電、核能發電、風力發 電與太陽能發電等’其中水力發電、風力發電與太陽能 發電利用大自然之水力、風力、太陽能進行發電,不但 來源不虞匱乏’且可以重複使用因此歸類為再生能源, 且不若火力發電與核能發電具破壞環境生態之影響,火 力發電所需的燃煤亦有短缺的疑慮,因此再生能源漸受 注目,現今針對太陽能發電系統之推行,目前許多國家 皆由政府獎勵補助於一般住宅或商用場所設置太陽能發 電系統’使得相對於成本較市電高出許多之太陽能發電 系統的接收度得以提高,太陽能發電系統之市場才能加 速成長,良性循環使得發電成本亦迅速下降。 此外,由於現今攜帶式電子產品風行,例如:行動 電話、PDA、DV等攜帶式3C產品,功能曰新月異相對耗 電也隨之提高,因此料式電子產品的待機及運作時門 將更顯重要,一般經常出差或旅遊的民眾多會攜帶傷用 電源,來延長攜帶式電子產品的待機及使用時間 表單编號A0101 第3頁/共26頁 了不影響攜帶方便性,備用電源的外形也要求小巧玲窥 使用方便,許多使用者也會隨身攜帶相關的充電設備, 以便隨時為備用電源或是電子產品作充電的準備,例如: 座充、旅充等,但無論是座充或旅充皆是利用—連接線 插接市電,並經過變壓器轉換為直流電,來對電子產品 充電,若遇到停電,或是在戶外,則無法取得電力來源 ’此時即使充電設備如何方便使用也派不上用場。 因此’針對攜帶式電子裝置之充電方便性,遂發展 出應用於攜帶式電子裝置之充電裝置,例如:藍芽耳機之 太陽能充電裝置、行動電話之太陽能充電裝置。且,對 於習知充電器皆透過連接器與攜帶式電子裝置電性連接 ,以進行充電,因而造成攜帶式電子装置之外殼需設置 開口供連接器使用,而造成濕氣容易從外殼開口接觸外 露之連接器甚至内部電路,一般電子元件容易受到濕氣 影響而故障,例如:手機設置一電源插孔用於連接充電器 ,對手機充電,因此濕氣將容易從電源插孔接觸手機之 充電連接β ’再者,使用者使用不當亦會造成連接器毀 扣。又,一般攜帶式電子裝置之充電裝置無法針對不同 電源規格之攜帶式電子裝置進行充電,充電裝 置需針對 每種電源規格設置對應之連接器,因此使用者需準傷 不同電源規格之充電連接器,以供充電這將造成使用 上的不便利性。因此現今充電裝置除了需考慮充電連接 β外露電性連接之;^可靠性,也需針對多種電源規格的 情況下,提供更具便利性U電方式。 有鑑於此’本創作提出—種無線充電裝置,其改善 習知充電不便利、不可靠的問題,兼具改善單-電源規 表單编號Α0101 第4頁/共26頁 [0003] 格的問題,以增加充電便利性。 【新型内容】 本創作之主要目的,在於提供一種無線充電裝置, 其利用無線充電方式,用於針對電子裝置進行無線充電 ,增加充電便利性並避免連接器外露所衍生的可靠性問 題。 本創作係提供一種無線充電裝置,其藉由一電源電 路提供一供應電源至充電控制電路,以供充電控制電路 對蓄電單元充電而儲存供應電源,蓄電單元係耦接一轉 換電路,並藉由轉換電路將供應電源轉換為複數輸出電 源,再由無線電力傳送單元經接收該些輸出電源後轉換 為對應之無線訊號,以發送至遠端之電子裝置,以供充 電,由於該些輸出電源具不同電壓準位,因此可供不同 電源規格之電子裝置用於充電,且搭配無線充電功能, 更可供不同電源規格之電子裝置同時藉由接收對應於輸 出電源之無線訊號,以進行充電,如此本創作改善戶外 充電不便及單一充電規格之問題而改善民眾之充電便利 性。 茲為使貴審查委員對本創作之結構特徵及所達成 之功效更有進一步之瞭解與認識,謹佐以較佳之實施例 圖及配合詳細之說明,說明如後: 【實施方式】 請參閱第一A圖與第一B圖,其為本創作之無線充電 裝置之一實施例之方塊圖。如圖所示,本創作之無線充

[0001] [0002] New description: [New technical field] The present invention relates to a charging device, and more particularly to a wireless charging device. [Prior Art] In today's technologically advanced era, human beings cannot escape the use of electrical appliances, such as household appliances, computers, lighting equipment, etc., all of which must be operated by using power supplies. Transmission and distribution systems are available, and power generation methods can be classified into thermal power generation, hydroelectric power generation, nuclear power generation, wind power generation, and solar power generation depending on the way electricity is generated. Among them, hydropower, wind power, and solar power use the power and wind of nature. Solar power generation, not only is the source not lacking, and can be reused, so it is classified as renewable energy, and if thermal power generation and nuclear power generation have the impact of environmental and ecological damage, there is also a shortage of coal for thermal power generation. Renewable energy is gaining attention. Nowadays, for the implementation of solar power generation systems, many countries are now subsidized by the government to provide solar power generation systems in general residential or commercial locations, so that the solar power generation system with a higher cost than the commercial power can be received. improve Market in order to accelerate the growth of solar power generation system, a virtuous cycle so that power generation costs also decline rapidly. In addition, due to the popularity of today's portable electronic products, such as mobile 3C products such as mobile phones, PDAs, and DVs, the relative power consumption of the products is also increasing. Therefore, the standby and operation of the electronic products will be more prominent. Important, people who travel frequently or travel often carry the power supply to extend the standby and use time of portable electronic products. Form No. A0101 Page 3 of 26 does not affect the portability. The shape of the backup power supply is also It is easy to use and small, and many users will carry relevant charging equipment with them to prepare for charging the backup power or electronic products at any time, such as: charger, travel charger, etc., but whether it is a charger or a travel charger They use the connection cable to plug in the mains and convert it to DC power through the transformer to charge the electronic products. If there is a power outage or outdoors, the power source cannot be obtained. At this time, even if the charging device is convenient to use, it is not sent. It comes in handy. Therefore, for the convenience of charging of portable electronic devices, a charging device for portable electronic devices such as a solar charging device for Bluetooth headsets and a solar charging device for mobile phones has been developed. Moreover, the conventional charger is electrically connected to the portable electronic device through the connector for charging, thereby causing the outer casing of the portable electronic device to be provided with an opening for the connector to be used, thereby causing moisture to be easily exposed from the opening of the outer casing. The connector or even the internal circuit, the general electronic components are easily affected by moisture and malfunction. For example, the mobile phone is provided with a power jack for connecting the charger to charge the mobile phone, so moisture will easily contact the charging connection of the mobile phone from the power jack. β 'again, improper use of the user will also cause the connector to be destructed. Moreover, the charging device of the general portable electronic device cannot charge the portable electronic device with different power specifications. The charging device needs to set the corresponding connector for each power supply specification, so the user needs to insure the charging connector of different power supply specifications. For charging this will cause inconvenience in use. Therefore, in today's charging devices, in addition to the charging connection β exposed electrical connection; ^ reliability, it is also necessary to provide more convenient U-electric mode for a variety of power supply specifications. In view of the fact that the present invention proposes a wireless charging device, which improves the problem that the conventional charging is inconvenient and unreliable, and has the problem of improving the single-power supply form number Α0101, page 4/26 pages [0003] To increase the convenience of charging. [New Content] The main purpose of the present invention is to provide a wireless charging device that utilizes a wireless charging method for wirelessly charging an electronic device, increasing charging convenience and avoiding reliability problems derived from connector exposure. The present invention provides a wireless charging device that provides a power supply to a charging control circuit by a power supply circuit for charging control circuit to charge the power storage unit to store the power supply, and the power storage unit is coupled to a conversion circuit by The conversion circuit converts the supply power into a plurality of output power sources, and the wireless power transmission unit receives the output power sources and converts them into corresponding wireless signals for transmission to the remote electronic device for charging, because the output power supplies Different voltage levels, so that electronic devices with different power specifications can be used for charging, and with wireless charging function, electronic devices of different power specifications can also be charged by receiving wireless signals corresponding to the output power. This creation improves the convenience of outdoor charging and the problem of single charging specifications to improve the convenience of charging.
