請參照第1圖、第2圖及第3圖，第1圖繪示依照本發明一實施例之車用顯示器100的示意圖，第2圖繪示依照本發明一實施例之車用顯示器100的分解示意圖，第3圖繪示依照本發明一實施例之車用顯示器100的剖面示意圖。車用顯示器100包括一顯示器模組110、一底座120、一轉軸部130、一可變阻尼流體140以及一潰縮支撐架150。Please refer to FIG. 1, FIG. 2 and FIG. 3. FIG. 1 shows a schematic diagram of a vehicle display 100 according to an embodiment of the present invention, and FIG. 2 shows a diagram of a vehicle display 100 according to an embodiment of the present invention. An exploded view, FIG. 3 shows a schematic cross-sectional view of a vehicle display 100 according to an embodiment of the present invention. The vehicle display 100 includes a display module 110 , a base 120 , a shaft portion 130 , a variable damping fluid 140 and a crush support frame 150 .

顯示器模組110及底座120例如設置於車輛的儀表板及中控台上，可採用浮懸式設計，跳脫以往內嵌式機構的限制，如此，螢幕的顯示面積加大，例如9至12吋或更大，可顯示大量的影音資訊、地圖及行車資訊等。顯示器模組110例如為液晶顯示器、有機發光二極體顯示器之類或其他合適安裝在車輛的防眩光顯示器。The display module 110 and the base 120 are, for example, arranged on the instrument panel and the center console of the vehicle, and can adopt a floating design to escape the limitations of the previous built-in mechanism. In this way, the display area of the screen is increased, such as 9 to 12 inch or larger, it can display a large amount of audio-visual information, maps and driving information, etc. The display module 110 is, for example, a liquid crystal display, an organic light emitting diode display, or other anti-glare displays suitable for installation in vehicles.

轉軸部130樞接於顯示器模組110與底座120之間，以使顯示器模組110相對於底座120可轉動。如第2圖所示，轉軸部130位於顯示器模組110的後套筒112中，且轉軸部130的兩端可藉由二插銷136而固定在底座120的支架122上，以使轉軸部130可轉動。此外，轉軸部130更可包括一正電極板132以及一負電極板134，正電極板132與負電極板134例如由二個同心圓柱組成，正電極板132與負電極板134相隔一間隙，例如1mm或其他數值，可供填入可變阻尼流體140。在本實施例中，負電極板134位於正電極板132中，且正電極板132與負電極板134的兩端以油封142密封，以防止可變阻尼流體140外漏。在另一實施例中，正電極板132例如位於負電極板134中，本發明不以此為限。The hinge portion 130 is pivotally connected between the display module 110 and the base 120 so that the display module 110 can rotate relative to the base 120 . As shown in FIG. 2, the shaft portion 130 is located in the rear sleeve 112 of the display module 110, and the two ends of the shaft portion 130 can be fixed on the bracket 122 of the base 120 by two pins 136, so that the shaft portion 130 can be rotated. In addition, the rotating shaft part 130 may further include a positive electrode plate 132 and a negative electrode plate 134, the positive electrode plate 132 and the negative electrode plate 134 are composed of two concentric cylinders, the positive electrode plate 132 and the negative electrode plate 134 are separated by a gap, For example, 1 mm or other values can be filled into the variable damping fluid 140 . In this embodiment, the negative electrode plate 134 is located in the positive electrode plate 132 , and both ends of the positive electrode plate 132 and the negative electrode plate 134 are sealed with an oil seal 142 to prevent the variable damping fluid 140 from leaking out. In another embodiment, the positive electrode plate 132 is located in the negative electrode plate 134, for example, the invention is not limited thereto.

請參照第3圖，可變阻尼流體140可電控地容置於正電極板132與負電極板134之間。在本實施例中，可變阻尼流體140例如為電流變液（electro-rheological fluid）或磁流變液(magnetorheological fluid)，為可用電場或磁場改變其流動性能（主要為黏滯係數或阻尼力）的流體。電流變液一般是由半導體顆粒在介電質油中組成懸浮液；而磁流變液則是由磁性顆粒在非磁性油類中組成的懸浮液。二種流體的流動原理是相同的，其中電場使電流變液的半導體顆粒極化；磁場使磁流變液的磁性顆粒磁化，並成線狀分佈，進而使電流變液或磁流變液的流動性能改變。當電場或磁場去掉後，電流變液或磁流變液的流動性能又可復原。Referring to FIG. 3 , the variable damping fluid 140 is electrically controllably accommodated between the positive electrode plate 132 and the negative electrode plate 134 . In this embodiment, the variable damping fluid 140 is, for example, electro-rheological fluid or magnetorheological fluid, which can be used to change its flow properties (mainly viscous coefficient or damping force) with an electric field or a magnetic field. ) of the fluid. Electrorheological fluid is generally a suspension composed of semiconductor particles in dielectric oil; while magnetorheological fluid is a suspension composed of magnetic particles in nonmagnetic oil. The flow principle of the two fluids is the same, in which the electric field polarizes the semiconductor particles of the electrorheological fluid; the magnetic field magnetizes the magnetic particles of the magnetorheological fluid and distributes them in a linear shape, thereby making the Changes in flow properties. When the electric field or magnetic field is removed, the flow performance of the electrorheological fluid or magnetorheological fluid can be restored.

也就是說，可變阻尼流體140受一外加電場或磁場施加而具有一第一阻尼力，且可變阻尼流體140未受外加電場或磁場施加而具有一第二阻尼力，第一阻尼力大於第二阻尼力。第一阻尼力為極化後的電流變液凝固而形成，可做為阻隔外部振動的制振力，而第二阻尼力為非極化的電流變液所形成，可供後續車輛撞擊時利用潰縮機制來吸收頭部撞擊力道。That is to say, the variable damping fluid 140 has a first damping force when it is applied by an external electric field or magnetic field, and the variable damping fluid 140 has a second damping force when it is not applied by an external electric field or magnetic field. The first damping force is greater than Second damping force. The first damping force is formed by the solidification of the polarized electro-rheological fluid, which can be used as a damping force to block external vibrations, while the second damping force is formed by the non-polarized electro-rheological fluid, which can be used in subsequent vehicle collisions Crushing mechanism to absorb head impact force.

因此，本實施例的車用顯示器100可利用可變阻尼流體140極化後的流動性能（黏滯係數或阻尼力增加）進行隔振，以吸收來自車輛的動力系統或底盤經由路面傳遞而來的振動，並可利用可變阻尼流體140非極化的流動性能（黏滯係數或阻尼力降低），使車用顯示器100能於車輛發生碰撞的瞬間啟動潰縮機制，來吸收頭部撞擊力道，避免頭部撞擊車用顯示器100時的加速度過高，以符合車用顯示器100的法規要求。Therefore, the vehicle display 100 of this embodiment can use the polarized flow properties of the variable damping fluid 140 (increased viscosity coefficient or damping force) for vibration isolation, so as to absorb vibrations transmitted from the vehicle's power system or chassis via the road surface. Vibration of the variable damping fluid 140 can be utilized without polarization (viscosity coefficient or damping force is reduced), so that the vehicle display 100 can activate the collapse mechanism at the moment of the vehicle collision to absorb the force of the head impact , to avoid excessive acceleration when the head hits the vehicle display 100 , so as to comply with the regulatory requirements of the vehicle display 100 .

在一實施例中，潰縮支撐架150例如為金屬、塑膠或其他等效材質所製成，其例如以二鎖固件152固定而連接於顯示器模組110與底座120之間。潰縮支撐架150具有一潰縮區154，可於車輛發生碰撞的瞬間或控制系統失效未供電時，受到撞擊而產生潰縮，使得顯示器模組110相對於轉軸部130旋轉，以吸收頭部的撞擊力道。也就是說，當車輛發生碰撞的瞬間或控制系統失效未供電時，可變阻尼流體140的阻尼力降低而無法提供適當的支撐，此時，潰縮支撐架150可做為輔助固定之用，也可以避免顯示器模組110相對於底座120產生不必要的轉動。 第二實施例 In one embodiment, the crush support frame 150 is made of metal, plastic or other equivalent materials, and is connected between the display module 110 and the base 120 by being fixed with two locking pieces 152 , for example. The crushing support frame 150 has a crushing area 154, which can be crushed when the vehicle collides or the control system fails to supply power, so that the display module 110 rotates relative to the shaft part 130 to absorb the head. impact force. That is to say, when the vehicle collides or the control system fails to supply power, the damping force of the variable damping fluid 140 is reduced and cannot provide proper support. At this time, the collapse support frame 150 can be used as an auxiliary fixation. It can also avoid unnecessary rotation of the display module 110 relative to the base 120 . second embodiment

請參照第4圖及第5圖，其分別繪示依照本發明另一實施例之轉軸部130’的分解示意圖及剖面圖。本實施例之轉動軸130’與上述第一實施例之轉動軸130的功能大致上相同，不同之處在於：第一實施例的正電極板132與負電極板134由二個表面平滑的同心圓柱組成，而本實施例的正電極板132’與負電極板134’由二個表面具有相對凹凸結構的同心圓柱組成，以增加極板間的通道長度及通道面積。因此，更多的可變阻尼流體140可填入波浪狀或凹凸狀的間隙中，並提高可變阻尼流體140的極化功用。Please refer to FIG. 4 and FIG. 5, which respectively illustrate an exploded schematic view and a cross-sectional view of a shaft portion 130' according to another embodiment of the present invention. The function of the rotating shaft 130' of this embodiment is substantially the same as that of the rotating shaft 130 of the above-mentioned first embodiment. In this embodiment, the positive electrode plate 132' and the negative electrode plate 134' are composed of two concentric cylinders with relatively concave-convex structures on the surface, so as to increase the channel length and channel area between the plates. Therefore, more variable damping fluid 140 can be filled into the wavy or concave-convex gap, and the polarization function of the variable damping fluid 140 can be improved.

在本實施例中，負電極板134’例如由兩個具有段差面且可插置為一體的凸柱133、135所組成，以形成中間凹入而兩側凸起的圓柱。負電極板134’的兩個凸柱133、135可分別由正電極板132’的兩端插入而容置於正電極板132’中，接著，正電極板132’與負電極板134’的兩端再以油封142密封，以防止可變阻尼流體140外漏，如第5圖所示。In this embodiment, the negative electrode plate 134' is composed of, for example, two protruding columns 133, 135 with stepped surfaces that can be inserted into one body to form a cylinder with a concave center and convex sides. The two protrusions 133, 135 of the negative electrode plate 134' can be respectively inserted into the two ends of the positive electrode plate 132' and accommodated in the positive electrode plate 132', and then, the positive electrode plate 132' and the negative electrode plate 134' Both ends are sealed with oil seals 142 to prevent the variable damping fluid 140 from leaking, as shown in FIG. 5 .

請參照第6圖及第7圖，其中第6圖繪示依照本發明一實施例之車用顯示器100的控制系統10的示意圖，第7圖繪示依照本發明一實施例之車用顯示器100的控制流程的示意圖，控制流程包括下列步驟S10至S60。Please refer to Figures 6 and 7, wherein Figure 6 shows a schematic diagram of a control system 10 of a vehicle display 100 according to an embodiment of the present invention, and Figure 7 shows a vehicle display 100 according to an embodiment of the present invention A schematic diagram of the control flow, the control flow includes the following steps S10 to S60.

The pre-driver 50 can turn on the driving switch 52 when the vehicle collides, so as to provide the power supply 60 to the explosive driver 54, and use the explosive driver 54 to activate the airbag 80 and the seat belt pretensioner 90 to protect the safety of passengers. The controller 20 is, for example, a trip computer, which detects whether the vehicle power is on or the vehicle engine is on (please refer to step S10), and if it is determined that the vehicle power/engine is on, it further determines whether the vehicle has collided (please refer to step S20).

此外，高電壓電源轉換器70用以提供一外加電場於車用顯示器100的可變阻尼流體140，當控制器20偵測到外力撞擊時可提供一電源關閉訊號至高電壓電源轉換器70，以切斷外加電場或磁場（請參照步驟S30），使可變阻尼流體140的阻尼力降低（請參見步驟S40），進而使車用顯示器100能於車輛發生碰撞的瞬間啟動潰縮機制，來降低頭部撞擊力道。另外，當控制器20未偵測到外力撞擊時，控制器20可提供一電源開啟訊號至高電壓電源轉換器70，以提供外加電場或磁場（請參見步驟S50），以使可變阻尼流體140的阻尼力增加（請參見步驟S60），做為阻隔外部振動的制振力。In addition, the high-voltage power converter 70 is used to provide an external electric field to the variable damping fluid 140 of the vehicle display 100. When the controller 20 detects an external impact, it can provide a power-off signal to the high-voltage power converter 70 to Cut off the applied electric field or magnetic field (please refer to step S30), so that the damping force of the variable damping fluid 140 is reduced (please refer to step S40), so that the vehicle display 100 can activate the collapse mechanism at the moment of the vehicle collision to reduce Head impact force. In addition, when the controller 20 does not detect an external impact, the controller 20 can provide a power-on signal to the high-voltage power converter 70 to provide an external electric field or magnetic field (see step S50), so that the variable damping fluid 140 The damping force of is increased (see step S60), as a damping force for isolating external vibrations.
