按，本發明人之前發明，中華民國專利第I646468號「車輛掛牌無線電子識別器」，係一識別器匹配一車輛安裝在車輛掛牌處，可用一無線射頻讀取器進行無線識別；該識別器，至少包括一承牌板件，一無線射頻標籤及一封槽片；該承牌板件，係由絕緣高分子材料成型，具有一板片體，該板片體之板面，相對車牌之一對安裝孔，設有一對穿孔，且一邊端成型有一斷面呈L型的標籤設置框部，該標籤設置框部，具有一長形條框體，該長形條框體與該板片體之間形成有一ㄇ型的插牌槽，該插牌槽之一段，是由該板片體開設一鏤空孔而顯露出該長形條框體一部份內面，且該長形條框體內面在該鏤空孔處的顯露，並設有一長凹槽；該無線射頻標籤，係裝設在該長形條框體的長凹槽中，為一相對該常凹槽形狀的長條形超高頻電子標籤，具有一絕緣基材薄片，該絕緣基材薄片的一端表面上，設有一金屬薄膜天線，該金屬薄膜天線上開設有一破孔槽，該破孔槽至一長邊開設有一溝槽，並由該溝槽的兩邊作為迴路焊盤(Pad)，電性連接一無線射頻識別晶片(RFID IC)；該封槽片，為一絕緣材料成型的條片，係固設 在該長條形框體的長凹槽的槽口上，將該無線射頻標籤封閉在該長凹槽內； According to the inventor, the Republic of China Patent No. I646468 "Wireless Electronic Identifier for Vehicle Registration" is an identifier that matches a vehicle and is installed at the vehicle registration place, and a radio frequency reader can be used for wireless identification; the identifier , including at least a plate-bearing plate, a radio frequency tag and a groove piece; the plate-bearing plate is made of insulating polymer material and has a plate body, and the plate surface of the plate body is opposite to the license plate. A pair of mounting holes are provided with a pair of perforations, and a label setting frame part with an L-shaped cross section is formed at one end. The label setting frame part has a long bar frame, and the long bar frame is connected to the plate. There is a U-shaped card slot formed between the bodies. A section of the card slot is made by opening a hollow hole in the plate body to expose a part of the inner surface of the long strip frame, and the long strip frame The inner surface of the body is exposed at the hollow hole and is provided with a long groove; the radio frequency tag is installed in the long groove of the long bar frame and is a long bar shape relative to the regular groove shape. The UHF electronic tag has an insulating base material sheet. On one end surface of the insulating base material sheet, a metal film antenna is provided.

唯，上述習用無線電子識別器，在車輛上作為無線識別，雖能抵抗金屬干擾及具有長距離讀取的效能，唯其承牌板件射出成型時，除大型板片體會甚為耗用塑料外，如圖1、2，射出成型之模具過程，基於條框體1內設無線射頻標籤，需具備足夠寬面的原因(插牌槽2的槽深度深)造成該ㄇ型的插牌槽2於脫模時阻抗大(滑塊3設置於板面上的接觸面積大，不易退模)、退模行程X1時間冗長(滑塊3的滑移距離M1較長，以20度斜銷4為例，當插牌槽2的槽深，為匹配無線射頻標籤的深度22mm時，滑塊3的滑移距離M1，至少大於或等於22mm，則退模行程X1=2.75M1，至少需要60.5mm才能完成滑塊3退出插牌槽2動作)，模具的開/關模與維護需耗費較多時間與成本，故習知車輛掛牌無線電子識別器仍具有改善的空間。

本發明為達上述目的，特舉較佳實施例，並配合所附圖式，作詳細說明如下： In order to achieve the above objects of the present invention, preferred embodiments are specifically cited and described in detail as follows with reference to the accompanying drawings:
一種小型化車輛掛牌用電子識別器，如圖3~10，係一識別器匹配一車牌50安裝在車輛掛牌處，可用無線射頻讀取器(圖未示)進行無線識別；該識別器10，至少包括一匹牌件20、一無線射頻標籤30及一封槽蓋40；該匹牌件20，係由絕緣高分子(塑膠)材料射出成型，具有一襯牌板片21，該襯牌板片21，為從該車牌50上邊緣500延伸至牌面501，並略為含蓋過該牌面501上一對安裝孔51的小型板片，相對該對安裝孔51，設有一對鎖孔22，且該對鎖孔22之間的板片體上部，開設有一缺口形槽孔23，該缺口形槽孔23的缺口位置兩邊具有一對接腳部24，該對接腳部24之間的前緣，並外凸成型有一標籤設置座26，該標籤設置座26的兩側邊260、261及底邊262投射在該缺口形槽孔23上，為投射落在該缺口形槽孔23形狀尺寸範圍內的長條形座體，內部相對該車牌50的厚度，係由一對納牌段263距離該襯牌板片21的板面，形成有一插牌孔槽27，且該對納牌段2
63相互之間，並還形成有一與該襯牌板片21的板面呈一夾角斜度θ的斜面264，該斜面264上內凹設有一長槽孔形標籤收納槽28；該無線射頻標籤30，係裝設在該標籤設置座26的標籤收納槽28中，為一相對該標籤收納槽28形狀的長條形超高頻電子標籤，具有一絕緣基材薄片31，該絕緣基材薄片31的一端表面上，設有一金屬薄膜天線32，該金屬薄膜天線32上電性連接一超高頻無線射頻識別晶片35(UHF RFID IC)；該封槽蓋40，為一絕緣材料(如塑膠材料)成型的蓋體，係固設在該標籤收納槽28的槽口上，將該無線射頻標籤30封閉在該標籤收納槽28內；
A miniaturized electronic identifier for vehicle registration, as shown in Figures 3 to 10, is an identifier that matches a
如圖3，當車牌50欲在車輛的掛牌處上進行掛牌時，該車牌50的上邊緣500崁入該識別器10的插牌孔槽27內，並使該車牌50的該對安裝孔51分別與該識別器10的該對鎖孔22相對；如圖3、11、12，僅須安裝螺絲60一併貫穿該對安裝孔51及該對鎖孔22，即能將該車牌50及該識別器10一起安裝在車輛70的掛牌處上；車輛70前進方向上方之讀取器(圖未示)斜下發送電磁波訊號，對高速移動中的該識別器10進行識別讀取時，該標籤設置座26的斜面264內無線射頻標籤30可大範圍角度面向該讀取器通訊，以及，該車牌50與該斜面264間具有斜擴的隔離空間可避免該車牌50反射的電磁波干擾通訊；整體結構匹配車牌50用於車輛70上作為無線識別，有效提昇長距離讀取識別時的讀取距離與通訊穩定性，且生產製造時，如圖5，該匹牌件20的成型，除襯牌板片21小型化可以減省材料成本外，如圖13、14，射出模具80的公模81與母模82可相互直接以相同軸向
的開/關模動作完成該匹牌件20，還使模具80能夠由滑塊的省時設計，降低模具複雜性與製作成本(包括模具80可以更為耐用及更容易維護)，且模具80開/閉模時不存在有滑塊的滑動動作因素，更使該匹牌件20的射出成型工作，能夠由該模具80的開/關動作行程的顯著縮短，即開/關模行程X2，只須該匹牌件20(工件)總厚度T的2倍(X2≧2T)以上距離就足以完成該匹牌件20退模(相較於圖1、2習知技術，上述開/關模行程X2約只需習知模具開/關模行程X1的3分之1)，有效增進該匹牌件20的生產效率，進而獲取該識別器10的整體經濟效益提昇。
As shown in Figure 3, when the
根據上述實施例，如圖3、4、5，其中，該匹牌件20的該對鎖孔22，分別為ㄇ形槽孔，且各具有一扣接口220；俾當該識別器10欲在已掛牌的車輛上使用時(由於車輛領牌時大部分已完成掛牌)，可以不用完全卸下安裝螺絲60(即將安裝螺絲60放鬆不卸下)，僅須從車牌50背面由該扣接口220扣到安裝螺絲60螺桿上，即能使安裝螺絲60一併貫穿該車牌安裝孔51及該識別器鎖孔22，快速進行及完成該識別器10在車輛掛牌處的安裝工作。
According to the above embodiment, as shown in Figures 3, 4 and 5, the pair of
根據上述實施例，如圖4、5，其中，該襯牌板片21上的該對接腳部24，分別具有一延伸進入該缺口形槽孔23的缺口內一段距離，且厚度大於該襯牌板片21厚度的條塊25；俾使該標籤設置座26在該對接腳部24之間前緣成型，能由該條塊25的補強連接，達成良好的抗斷裂強度。
According to the above embodiment, as shown in Figures 4 and 5, the
根據上述實施例，如圖4、5，其中，該標籤設置座26外
型尺寸投射在該缺口形槽孔23上，該標籤設置座26的兩側邊260、261及底邊262，分別距離該缺口形槽孔23的兩孔側邊230、231及孔底邊232至少有1公厘(mm)以上，藉由該標籤設置座26的形體尺寸完全落在該缺口形槽孔23的孔形尺寸的投射範圍內，如圖13、14，俾使該匹牌件20在進行射出成型過程時的公、母模81、82對接，能夠由開/關模方向同軸的公模上模仁810，直接且完整的成型該插牌孔槽27，省去滑塊的設計或運用。
According to the above embodiment, as shown in Figures 4 and 5, the
根據上述實施例，如圖4、6、7，其中，該標籤設置座26內部的該對納牌段263相互之間，係以一段落差H(深度)成型該斜面264，如圖10、12，藉由該段落差H(深度)確保該納牌段263納入該車牌50時，能使該斜面264與該車牌50保持足夠距離，且呈傾斜擴孔槽孔的防干擾隔離空間。
According to the above embodiment, as shown in Figures 4, 6 and 7, the pair of
根據上述實施例，如圖4、6、7、8，其中，該標籤設置座26內部的該斜面264上，該標籤收納槽28的槽口周邊，係設有一封蓋槽溝280，且該封槽蓋40上，相對該封蓋槽溝280設有熱熔框條41，如圖10，藉由該熱熔框條41在封蓋槽溝280上超音波熱熔結合，乃使封槽蓋40在該斜面264上封閉該標籤收納槽28，達成該標籤收納槽28良好的防水浸入效果。
According to the above embodiment, as shown in Figures 4, 6, 7 and 8, a
根據上述實施例，如圖4、10，其中，該無線射頻標籤30裝設在該標籤收納槽28中，該標籤收納槽28內的空隙，係填充有絕緣封膠29，藉由該絕緣封膠29對該無線射頻標籤30產生活動限制，俾使該無線射頻標籤30在該標籤收納槽28內的裝設，達成組裝後平展
樣態的安定效果。
According to the above embodiment, as shown in FIGS. 4 and 10 , the
根據上述實施例，如圖4、9，其中，該無線射頻標籤30的該金屬薄膜天線32上開設有一長矩形破孔槽33，且該破孔槽33一長邊垂直開設有一破口形溝槽34，並由該溝槽34的兩邊作為迴路焊盤(Pad)，電性連接該無線射頻識別晶片35；藉由該破孔槽33的孔形尺寸大小及該溝槽34的槽寬尺寸調整電磁波訊號的感應頻段與場型，俾使無線射頻標籤能在使用頻段，達成良好讀取敏感度，並獲得長距離讀取效果；即，此一實施調整出台灣地區920~930MHz使用頻段，所完成的識別器成品經過測試，如圖15，讀效敏感-21dBm，如圖16，啟動電波-5dBm(低於0dBm)，如圖17，理論讀距16公尺(m)，相較於前案，本發明能在優異的讀取敏感度狀態下，達到更長距離的讀距(增加約4公尺)。
According to the above embodiment, as shown in Figures 4 and 9, the
根據上述實施例，如圖4、10，其中，該標籤設置座26上的該斜面264，其與該襯牌板片21的板面間夾角斜度θ，為15度至30度(較佳為20度)；如圖12，俾使襯牌板片21上承置的金屬車牌50上所反射的電磁波不易反投射到該斜面264上，確保該斜面264內該無線射頻標籤30與讀取器(圖未示)端的通訊不會受到金屬干擾。
According to the above embodiment, as shown in Figures 4 and 10, the
根據上述實施例，如圖10，該無線射頻標籤30，除可直接置入該標籤收納槽28中，由該封槽蓋40封閉該標籤收納槽28完成該無線射頻標籤30的組裝外，該封槽蓋40可以是如圖10A，為一種內面具有黏貼平面的封槽蓋40A，該無線射頻標籤30係貼設在該封槽蓋40A的內面組裝在該標籤收納槽28中，俾能確保該無線射頻標籤30在該標籤收納槽28中平整組裝。
