Field of the Invention This invention relates to a helmet, and more particularly to a method for dynamically providing a direction signal and a helmet using the same. [Prior Art] 近年来 In recent years, with the improvement of the quality of life, it is common for individuals to own transportation, and the locomotive is the main transportation at this stage. In order to take into account traffic safety, the direction lights in the left and right directions are arranged behind the locomotive. Therefore, when turning or changing lanes in the line, the rear lights are displayed by the display of the directional lights to avoid sending: For the direction lights currently located behind the locomotive, the relative position of the configuration is relatively low. Although 'when the locomotive is used in the road where the gambling is more gambling, and when the lane is changed or changed, the direction light is activated to inform that the position of the directional light is low, and the display effect achieved is currently a general user. A helmet is used to protect the safety of its head when riding a locomotive. Since the safety is worn on the head and the position is high, then all of the above = :=, direction or _ car = direction = several types of safety helmets are available for the user. Although the financial helmet can provide information on the direction of the news, it does not effectively provide the degree of turning and the message of 200927008. SUMMARY OF THE INVENTION The present invention provides a method for dynamically providing a direction signal and a helmet for using the same, thereby effectively providing a user with a state of turning and braking, and also displaying a segment display for the same.

The method includes the following steps: generating a first signal, a second signal, or a third signal according to a user's motion or speed change, wherein the first signal and the second signal are respectively tilted according to the user's tilt to the left The action of the right tilt is generated, and the third signal is generated according to the change of the speed of the user. The fourth signal, the fifth signal, or the sixth signal are respectively generated according to the strength of the first signal, the second signal, or the third signal.产生 Corresponding to the fourth signal ′ corresponding to generate a first light indication signal for indicating the degree to which the user tilts to the left. According to the fifth signal, the corresponding second light indicating signal is used to indicate the degree to which the user tilts to the right. According to the sixth signal, a corresponding speed change indication signal is generated to indicate the degree of change of the speed of the user. The invention generates different signals by means of an acceleration sensor (G-sensor) according to the user's motion or speed change (brake).

As a result, the helmet of the present invention can not only dynamically provide directions and speed changes (braking), but also display differently.
200927008 燈號，來表現出不同程度的㈣與速度變化(煞車力道）， 以有效地提供警示的訊息。 為讓本發明之上述特徵和優點能更明顯易懂，下文特 舉較佳實補，她合所酬式，作詳細說明如下。 【實施方式】 圖1為本發明—實施例之可動態提供方向訊號的安全 帽示意圖。請參照圖卜安全帽議包括加速度感測器 (G-麵〇Γ) 110、微處理器12〇、第一指示燈13〇、第二指 示燈140、煞車燈150與電源單幻6〇。如所知般加速度 感測器110會感測安全帽100的加速度大小。比如，當加 速度感測器110為2維加速度感測器時，則其可感測使用 者左右方向的傾斜加逮度或前後方向的加速度。所以，在 本實施例中，加速度感測器11〇可依據使用者之動作或速 度變化(如煞車或加速），而產生第一訊號s卜第二訊號 S2或第三訊號S3。其中，第一訊號S1、第二訊號％分別 為加速度感測器110依據使用者向左傾斜之動作、向右傾 斜之動作而產生的訊號，第三訊號S3為加速度感測器⑽ 依據使用者煞車而產生的訊號。在本說明書中，以騎機車 時之煞車為舰制，但本發明並*受限於此只要使用 者有速度變化’即可_第三訊號S3來指示使用 度變化程度。 此外，上述所謂的傾斜加速度所代表的意思比如包括 使用者的傾斜程度，也就是對應於機車轉彎的程度。如所 知般，加速度感測器110可以感測到使用者在左右傾斜時 8 200927008 所造成的加速度讀值變化，此加速度讀值變化可利用灣算 法來轉換成使用者的傾斜角度。故而，在本實施例中，逯 過加速度感測器110所感測到的加速度讀值變化，可礅夠 使用者的傾斜角度。 微處理器120耦接加速度感測器110,用以接收第〜 訊號S1、第二訊號S2與第三訊號S3，並據以分別產生第 四訊號S1，、第五訊號S2,與第六訊號S3,。另外，第〜指 示燈130、第二指示燈14〇與煞車燈150耦接微處理器 120 °其中，第一指示燈130會依據第四訊號S1，，並對應 的產生第一光指示訊號，而此第一光指示訊號可以指示使 用者向左傾斜之程度。第二指示燈14〇會依據第五訊號 S2’ ’並對應的產生第二光指示訊號，而此第二光指示訊號 可以指示使用者向右傾斜之程度。煞車燈15〇會依據第六 訊號S3’，並對應的產生煞車指示訊號，而此煞車指示訊 號可以指示使用者之煞車力道程度。 電源單元160耦接微處理器120，用以提供微處理器 120所需之工作電壓。在本實施例中，電源單元16〇例如 為可充電電池、太陽能電池或鈕釦型電池等其他相類似元 件。另外，第一指示燈13〇、第二指示燈14〇與煞車燈15〇 例如為發光二極體(lightemittingdi〇de，LED)。此外，第一 指不燈130、第二指示燈14〇與煞車燈15〇之配置關係可 以如圖2所不，也就是第一指示燈130配置於安全帽1〇〇 之後方左側的位置上，第二指示燈14〇配置於安全帽1〇〇 之後方右侧的位置上，煞車燈15〇配置於安全帽1〇〇之後 9 200927008 方中間的位置上。 上述已說明安全帽1()()各元件之間_接_以及各 元件的功用。接下來，將進一步說明安全帽1〇〇如何可以 祕提供方向峨的運作綠。首先，假設—制者配戴 此安全帽100並且駕啟機車由一出發地行駿至—目的地。 當使用者在行駛途中向左轉時，使用者會將機車向左傾斜 以達到左轉彎的目的，由於使用者乘坐於機車上，因此也 會隨著機車而向左傾斜。此時，安全帽100上的加速度感 測器110會依據使用者向左傾斜之動作，並對應的產生第 一訊號S1。 承上述’使用者向左傾斜的程度（亦即向左方向的傾斜 加速度)是對應於機車轉彎的程度，也就是說，若是機車於 左轉彎的程度較小時，則使用者向左傾斜的程度也較小， 若是機車左轉彎的程度較大時，則使用者向左傾斜的程度 相對的也比較大。因此，加速度感測器110所產生第一訊 號S1也會有強弱之分。微處理器120會依據訊號S1的強 ❹ 弱’而對應的控制訊號S1’的強弱，並輸入至第一指示燈 130。接著，第一指示燈130會對應的產生第一光指示訊 號，以便告知後方的車輛此使用者所駕駛的機車正向左轉 彎。 另外，第一指示燈130會因應訊號S1’之強弱而產生 不同程度的第一光指示訊號，如圖3A與圖3B所示，以顯 示出轉彎程度的不同。由圖3A可看出，由於弱訊號si， 為使用者向左傾斜的程度較小，因此於第一指示燈130上 200927008 少。由圖3B可看出，由於強訊號S1， 為使用者向左傾斜的程度鼓，因此於第—指示燈i3〇上 所党起的LED健較多。藉此，安全帽1〇〇不僅可有效地 還可以藉由顯示不同形式的燈號來表 接下來，當使用者於行敬途甲向右轉的運作流程，則 可以藉由上述向左轉之說明來推得，故在此不再費述。另 外，本實施例同樣地可以藉由加速度感測器⑽依據使用 者向右傾斜的程度（亦即向右方向的傾斜加速度）大小不 同’而於第二指示燈14〇上顯示出來，並且如圖4A與圖 4B所示。 在本實施例中，當使用者於行駛途中進行煞車時，會 產生一個與機車前進相反的加速度，以達到敔 ❹ 此時，安全帽励上加速度感廳⑽會依據上述^反的 加速度，而對應的產生第三訊號S3。舉例來說，若是機車 在較慢的速度下進行煞車，所產生的煞車力道相對的比較 小，因此，加速度感測器110所產生的第三訊號S3也較 弱。若是機車在較快的速度下進行煞車，例如是緊急煞車 時’所產生的煞車力道相對的比較大，因此，加速ϋ測 器110所產生的第三訊號S3也較強。 又 之後，微處理器120會依據所接收的第三訊號幻，而 對應的產生第六訊號S3,，並輸入至煞車燈15〇。最後，煞 車燈150會依據第六訊號S3,，而對應的產生煞車指示訊 號，以便告知後方的車輛此使用者所駕駛的機車正進行煞 11 200927008 車。 另外，煞車燈150也可以依據訊號S3,的強弱，而產 生不同程度的煞車指示訊號，如圖5A與圖5B所示。由圖 5A可看出，當訊號S3,的信號強度較弱時，煞車燈15〇上 所亮起的LED個數較少，也是反映著使用者當時煞車的力 道程度較小。由圖5B可看出，當訊號S3,的信號強度較強 時，煞車燈150上所亮起的LED個數較多，也是反映著使 用者當時煞車的力道程度較大。藉此，此安全帽丨⑼不僅 可有效地動態提供煞車訊息，還可以藉由顯示不同形式的 燈號來表現煞車力道程度的大小。 值得一提的是，由於使用者在行駛途中欲向左或向右 轉時，通常會先煞車降低行車速度以便進行轉彎的動作， 因此，加速度感測器110會同時偵測到煞車以及向左或向 右的狀態，使得安全帽100上的第一指示燈130與煞車燈 150會在同一時間亮起，或是第二指示燈14〇與煞車燈15〇 會在同一時間焭起。如此一來，更可有效地提供使用者的 駕駛狀況給後方車輛。另外，在上述實施例中，是以2段 顯不的方式，但本發明不限於此，亦可視使用者所需而將 顯示的方式分為3段或3換以上，故在此不再贅述。 在上述實施例中，是以使用者駕駛機車為例，來說明 安全帽100所能達成的功效，但本發明不限與此，亦可用 於使用者駕駛自行車、電動腳踏車或使用直排輪與滑板等。 從另一個觀點來看，本發明提出一種可動態提供方向 訊號之方法。圖6為本發明一實施例之可動態提供方向訊 12 200927008

Q 步驟’以下再舉一實施例來說明本發明之動態提供方向訊 號的詳細流程。圖7為本發明另一實施例之可動態提供方 向訊號的方法流程圖。請參照圖7,首先，在步驟S702中， 依據，用者之動作或煞車（亦即速度變化），而分別產生第 —訊號S1、第二訊號S2或第三訊號S3。其中，第一訊號 S1 γ第二訊號S2分別依據使用者向左傾斜之動作、向右 傾斜之動作而產生，第三訊號S3為依據使用者煞車而產 ^。在步驟S704中，依據第一訊號81、第二訊號S2或第 —訊號S3之強弱，而分別對應的產生第四訊號S1，、第五 13 200927008 訊號S2’或第六訊號S3,。 在步驟S706中，依據第四訊號81，，而對應的產生第 一光私示訊號，用以指示使用者向左傾斜之程度。在步驟 S708中，配置第一指示燈13〇於安全帽1〇〇之後方左側的 位置上，以顯示第一光指示訊號。在步驟S71〇中，依據 第五訊號S2’，而對應的產生第二光指示訊號，用以指示 使用者向右傾斜之程度。在步驟S712中，配置第二指示 燈140於安全帽1〇〇之後方右侧的位置上，以顯示第二光 指示訊號。在步驟S714中，依據第六訊號S3,，而對應的 產生煞車指示訊號，用以指示使用者之煞車力道程度。在 步驟S716中，配置煞車燈150於安全帽1〇〇之後方中間 的位置上’以顯示煞車指示訊號。 综上所述，本發明藉由加速度感測器（G_sens〇r)依據 使用者之動作（亦即向左、向右之動作)或速度變化(煞車）， 而對應的產生不同的訊號。之後，經由微處理器將上述訊 號處理後，分別輸出至第一指示燈、第二指示燈以及速度 變化(煞車)燈，以產生第一光指示訊號、第二光指示訊號 以及速度變化（煞車）指示訊號，來顯示使用者使用的狀 況。另外，加速度感測器更可以依據使用者之向左、向右

warning messages. In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following is a preferred embodiment of the invention. [Embodiment] FIG. 1 is a schematic diagram of a safety helmet capable of dynamically providing a direction signal according to an embodiment of the present invention. Please refer to the Tubu helmet for the acceleration sensor (G-face 110) 110, the microprocessor 12 〇, the first indicator light 13 〇, the second indicator light 140, the brake light 150 and the power supply single illusion. As is known, the acceleration sensor 110 senses the magnitude of the acceleration of the helmet 100. For example, when the acceleration sensor 110 is a 2-dimensional acceleration sensor, it can sense the inclination of the user in the left-right direction or the acceleration in the front-rear direction. Therefore, in this embodiment, the acceleration sensor 11 can generate the first signal S2 or the third signal S3 according to the user's motion or speed change (such as braking or acceleration). The first signal S1 and the second signal % are signals generated by the acceleration sensor 110 according to the user's tilting action to the left and the right tilting motion, and the third signal S3 is the acceleration sensor (10) according to the user. The signal generated by the brakes. In the present specification, the brake is used as a ship when riding a locomotive, but the present invention is limited to the extent that the degree of change in usage is indicated by the third signal S3 as long as the user has a speed change. Further, the above-mentioned so-called tilt acceleration means, for example, the degree of inclination of the user, that is, the degree of turning of the locomotive. As is known, the acceleration sensor 110 can sense the acceleration reading change caused by the user when tilting left and right 8 200927008, and the acceleration reading change can be converted into the user's tilt angle by using the Bay algorithm. Therefore, in the present embodiment, the acceleration reading value sensed by the acceleration sensor 110 can satisfy the inclination angle of the user. The microprocessor 120 is coupled to the acceleration sensor 110 for receiving the first signal S1, the second signal S2, and the third signal S3, and respectively generating the fourth signal S1, the fifth signal S2, and the sixth signal respectively. S3,. In addition, the first indicator light 130, the second indicator light 14 and the brake light 150 are coupled to the microprocessor 120°, and the first indicator light 130 generates a first light indication signal according to the fourth signal S1. The first light indication signal can indicate the extent to which the user is tilted to the left. The second indicator light 14 产生 generates a second light indication signal according to the fifth signal S2' ′, and the second light indication signal can indicate the degree to which the user tilts to the right. The brake light 15 will be based on the sixth signal S3', and correspondingly generate a brake indication signal, and the brake indication signal can indicate the degree of the user's braking force. The power unit 160 is coupled to the microprocessor 120 for providing the operating voltage required by the microprocessor 120. In the present embodiment, the power supply unit 16 is, for example, a similar component such as a rechargeable battery, a solar battery, or a button type battery. In addition, the first indicator light 13 〇, the second indicator light 14 〇 and the brake light 15 〇 are, for example, light emitting diodes (LEDs). In addition, the arrangement relationship between the first indicator light 130, the second indicator light 14〇 and the brake light 15〇 may be as shown in FIG. 2, that is, the first indicator light 130 is disposed on the left side of the helmet 1〇〇. The second indicator light 14 is disposed at a position on the right side of the rear side of the helmet 1 , and the brake light 15 is disposed at a position intermediate the helmet 1 9 9 200927008. The functions of the components of the helmet 1 () () and the components have been described above. Next, we will further explain how the helmet 1 can provide the operational green of the direction. First, assume that the manufacturer wears the helmet 100 and drives the locomotive from a place of departure to the destination. When the user turns left while driving, the user tilts the locomotive to the left to achieve the left turn. Since the user rides on the locomotive, it also tilts to the left with the locomotive. At this time, the acceleration sensor 110 on the helmet 100 is responsive to the left tilt of the user, and correspondingly generates the first signal S1. The extent to which the user tilts to the left (ie, the tilting acceleration to the left) corresponds to the degree of turning of the locomotive, that is, if the degree of the left turn of the locomotive is small, the user leans to the left. The degree is also small. If the degree of left turn of the locomotive is large, the degree of tilting of the user to the left is relatively large. Therefore, the first signal S1 generated by the acceleration sensor 110 also has a strong and weak component. The microprocessor 120 responds to the strength of the control signal S1' according to the strong ’ of the signal S1 and inputs it to the first indicator light 130. Then, the first indicator light 130 correspondingly generates a first light indication signal to inform the rear vehicle that the locomotive driven by the user is turning to the left. In addition, the first indicator light 130 generates different degrees of first light indicating signals according to the strength of the signal S1', as shown in Figs. 3A and 3B, to show the difference in the degree of turning. As can be seen from FIG. 3A, since the weak signal si is less inclined to the left by the user, there is less 200927008 on the first indicator light 130. As can be seen from Fig. 3B, since the strong signal S1 is drummed to the extent that the user tilts to the left, the LEDs on the first indicator light i3 are more healthy. In this way, the helmet 1 can be effectively and not only effectively displayed by displaying different types of lights. When the user turns the right direction of the road, the left turn can be performed by the above. The description is derived, so it will not be mentioned here. In addition, the embodiment can be similarly displayed on the second indicator light 14 by the acceleration sensor (10) according to the degree of inclination of the user to the right (that is, the inclination acceleration in the right direction), and 4A and 4B are shown. In this embodiment, when the user performs braking while driving, an acceleration opposite to the advance of the locomotive is generated to reach 敔❹. At this time, the acceleration sensing chamber (10) of the helmet is activated according to the above-mentioned acceleration. Correspondingly, a third signal S3 is generated. For example, if the locomotive brakes at a slower speed, the braking force generated is relatively small, and therefore the third signal S3 generated by the acceleration sensor 110 is also weak. If the locomotive is braking at a relatively fast speed, for example, during an emergency braking, the braking force generated by the locomotive is relatively large, so that the third signal S3 generated by the acceleration detector 110 is also strong. Then, the microprocessor 120 generates a sixth signal S3 corresponding to the received third signal, and inputs it to the brake light 15〇. Finally, the 车 headlight 150 will generate a brake indication signal according to the sixth signal S3, so as to inform the rear vehicle that the locomotive driven by the user is carrying out the 2009 11 200927008 vehicle. In addition, the brake light 150 can also generate different degrees of braking indication signals according to the strength of the signal S3, as shown in Figs. 5A and 5B. As can be seen from Fig. 5A, when the signal strength of the signal S3 is weak, the number of LEDs illuminated by the brake light 15 is small, which reflects that the user is less powerful at the time of braking. As can be seen from Fig. 5B, when the signal intensity of the signal S3 is strong, the number of LEDs illuminated by the brake light 150 is large, which also reflects the greater degree of force of the user at the time of braking. Thereby, the helmet 丨 (9) not only can effectively provide the braking information dynamically, but also can display the degree of the braking force by displaying different types of lights. It is worth mentioning that, because the user wants to turn left or right while driving, he usually starts to lower the driving speed to make a turning action. Therefore, the acceleration sensor 110 detects the braking and the left side at the same time. Or to the right state, the first indicator light 130 on the helmet 100 and the brake light 150 will light up at the same time, or the second indicator light 14 and the brake light 15 will be picked up at the same time. In this way, the driving condition of the user can be effectively provided to the rear vehicle. In addition, in the above embodiment, the method is shown in two stages, but the present invention is not limited thereto, and the manner of displaying may be divided into three segments or three or more according to the needs of the user, and therefore will not be described herein. . In the above embodiment, the user can drive the locomotive as an example to illustrate the effect that the helmet 100 can achieve, but the invention is not limited thereto, and can also be used for the user to drive a bicycle, an electric bicycle or use an in-line wheel. Skateboarding, etc. From another point of view, the present invention proposes a method of dynamically providing a direction signal. FIG. 6 is a flowchart of a method for dynamically providing direction information 12 200927008 according to an embodiment of the present invention. This embodiment is applicable to a helmet. Referring to FIG. 6, first, in step S602, the first signal S1, the second signal S2, or the third signal S3 are respectively generated according to the user's action or the brake '(ie, speed change)'. The first signal S1 and the second signal illusion are respectively generated according to the user's action of tilting to the left and tilting to the right, and the third signal S3 is generated according to the user's braking. In step S604, the corresponding signal 产生 generates a fourth signal S1', a fifth signal S2, or a sixth signal § 3 according to the strength of the first signal S1, the second signal S2 or the third signal S3. In step S606, according to the fourth signal 81, a corresponding first light button is generated to indicate the degree to which the user tilts to the left. In step = 608, according to the fifth signal S2, a corresponding second light indicating signal is generated to indicate the degree to which the user tilts to the right. In step S61, according to the sixth signal S3', a corresponding braking indication signal is generated to indicate the degree of braking force of the user. Further, in order to more clearly describe each of the above-described Q steps of the dynamic direction providing signal, a detailed flow of the dynamic direction providing signal of the present invention will be described below by way of an embodiment. FIG. 7 is a flowchart of a method for dynamically providing a direction signal according to another embodiment of the present invention. Referring to FIG. 7, first, in step S702, a first signal S1, a second signal S2, or a third signal S3 is generated according to the user's action or braking (ie, speed change). The first signal S1 γ and the second signal S2 are respectively generated according to the action of tilting the user to the left and tilting to the right, and the third signal S3 is generated according to the user's braking. In step S704, according to the strength of the first signal 81, the second signal S2 or the first signal S3, the fourth signal S1, the fifth 13 200927008 signal S2' or the sixth signal S3 are respectively generated. In step S706, according to the fourth signal 81, a corresponding first light private signal is generated to indicate the degree to which the user tilts to the left. In step S708, the first indicator light 13 is disposed at a position on the left side of the rear side of the helmet 1 to display the first light indication signal. In step S71, according to the fifth signal S2', a second light indicating signal is generated correspondingly to indicate the degree to which the user tilts to the right. In step S712, the second indicator light 140 is disposed at a position on the right side of the rear side of the helmet 1 to display the second light indication signal. In step S714, according to the sixth signal S3, a corresponding braking indication signal is generated to indicate the degree of braking force of the user. In step S716, the brake light 150 is disposed at a position intermediate the rear of the helmet 1 to display the brake indication signal. In summary, the present invention generates different signals correspondingly by the motion sensor (G_sens〇r) according to the user's motion (ie, the leftward and rightward motions) or the speed change (the brake). After that, the signal is processed by the microprocessor, and then output to the first indicator light, the second indicator light, and the speed change (brake) light to generate the first light indication signal, the second light indication signal, and the speed change. ) indicates a signal to indicate the status of the user. In addition, the acceleration sensor can generate different strong and weak signals according to the difference of the user's leftward, rightward or speed (the degree of braking). After the signal is processed by the microprocessor, the degree of turning and the speed change (the braking force) can be expressed by the number of LEDs illuminated by the first indicator light, the second indicator light or the speed change indicating (braking) lamp. different. In one case, the helmet of the present invention can not only dynamically provide direction and braking information, but also can display different degrees of turning and speed changes (braking force) with different display lights to achieve more effective.
