The electronic control device A has a first housing B and a second housing C that can be opened and closed to each other. The pivot mechanism 12 is provided between the first housing B and the second housing C of the electronic control device A. The first casing B has a display screen, and the second casing C has a keyboard 10, and the keyboard 10 is provided with a plurality of lifting keys 14. During the rotation of the first housing B, the application state of the lift button 14 is switched through the pivot mechanism 12. For example: when the first housing B is opened relative to the second housing C, the pivot mechanism 12 raises the key 14 to make it float out of the second housing C to facilitate the user's pressing operation; for example, the first housing B is relative to the second The housing C is closed, and the pivot mechanism 12 lowers the button 14 so that the electric control device A meets the ultra-thin appearance requirements.

樞軸機構12可包含第一轉軸16、橋接件18、第一連接件20、連桿組22、支撐件24、止擋件26、第一彈性元件28、第二轉軸30以及第二連接件32。橋接件18可樞接於第一轉軸16與第二轉軸30，且橋接件18還具有第一凸輪34。第一連接件20裝設在第二殼體C，連桿組22可轉動地設置於第一連接件20上、並且連結升降式按鍵14。第二連接件32設置於第二轉軸30且裝在第一殼體B。支撐件24可具有本體36、滑梢38與第二凸輪40。本體36滑動設置於第一轉軸16。滑梢38連結連桿組22，並且活動設置在第一連接件20之滑槽42內。第二凸輪40設置於本體36，用來滑動制動第一凸輪34。The pivot mechanism 12 may include a first rotating shaft 16, a bridge member 18, a first connecting member 20, a link group 22, a supporting member 24, a stopper 26, a first elastic element 28, a second rotating shaft 30 and a second connecting member 32. The bridge 18 can be pivotally connected to the first rotation shaft 16 and the second rotation shaft 30, and the bridge 18 also has a first cam 34. The first connecting member 20 is installed in the second housing C, and the connecting rod group 22 is rotatably disposed on the first connecting member 20 and is connected to the lifting button 14. The second connector 32 is disposed on the second rotating shaft 30 and is mounted on the first housing B. The support 24 may have a body 36, a slider 38 and a second cam 40. The body 36 is slidably disposed on the first rotating shaft 16. The sliding pin 38 is connected to the link group 22 and is movably disposed in the sliding slot 42 of the first connecting member 20. The second cam 40 is disposed on the body 36 and is used for slidingly braking the first cam 34.

第二凸輪40可包含相鄰接的突出部44以及平坦部46。如第3圖與第4圖所示，突出部44和平坦部46圍繞設置在本體36的側緣，使得第一凸輪34能順暢地從突出部44滑動至平坦部46、或是從平坦部46滑向突出部44。突出部44與平坦部46的比例關係會影響升降式按鍵14在第一殼體B相對於第二殼體C展開時的抬昇過程。舉例來說，平坦部46之寬度較佳可為突出部44之寬度的四倍，其中寬度係可表示為突出部44與平坦部46沿著本體36之環型結構的軌跡。在第一殼體B相對第二殼體C的翻轉過程中，升降式按鍵14只有四分之一的時間會受到樞軸機構12之驅動而抬昇。突出部44和平坦部46的寬度比例不限於前揭態樣所述，端視設計需求而定。The second cam 40 may include the adjacent protrusion 44 and the flat portion 46. As shown in FIGS. 3 and 4, the protruding portion 44 and the flat portion 46 surround the side edge of the body 36 so that the first cam 34 can smoothly slide from the protruding portion 44 to the flat portion 46 or from the flat portion 46滑向突部44。 44 sliding to the protrusion 44. The proportional relationship between the protruding portion 44 and the flat portion 46 will affect the lifting process of the lifting button 14 when the first housing B is unfolded relative to the second housing C. For example, the width of the flat portion 46 may be preferably four times the width of the protrusion 44, where the width can be expressed as the trajectory of the protrusion 44 and the flat portion 46 along the ring structure of the body 36. During the turning process of the first housing B relative to the second housing C, the lifting button 14 is driven by the pivot mechanism 12 to be lifted only a quarter of the time. The width ratio of the protruding portion 44 and the flat portion 46 is not limited to that described in the foregoing disclosure, and depends on the design requirements.

再者，止擋件26設置在第一轉軸16相對於橋接件18的一端。第一彈性元件28位於止擋件26與支撐件24。第一彈性元件28之兩端分別止抵止擋件26和支撐件24；當支撐件24受到第一凸輪34的推擠而沿著第一轉軸16往止擋件26移動時，第一彈性元件28壓縮以儲存彈性恢復力。第一凸輪34不再施壓第二凸輪40之突出部44時，第一彈性元件28的彈性恢復力可驅動支撐件24快速回復到初始位置。Furthermore, the stopper 26 is disposed at an end of the first rotating shaft 16 relative to the bridge 18. The first elastic element 28 is located on the stop 26 and the support 24. Both ends of the first elastic element 28 respectively stop against the stopper 26 and the support 24; when the support 24 is pushed by the first cam 34 and moves toward the stop 26 along the first rotation axis 16, the first elasticity The element 28 compresses to store the elastic restoring force. When the first cam 34 no longer presses the protruding portion 44 of the second cam 40, the elastic restoring force of the first elastic element 28 can drive the support 24 to quickly return to the initial position.

連桿組22可包含第一連桿48以及第二連桿50。第一連桿48的第一端52連接於滑梢38，第二端54經由第二連桿50連接升降式按鍵14。第一連桿48的轉折端56位於第一端52與第二端54之間，用以樞接第一連接件20。因此，滑梢38在滑槽42內移動，會牽引第一連桿48以轉折端56為軸心旋轉，進而帶動第二連桿50之位移。在本發明較佳實施例中，連桿組22還可進一步包含第三連桿58。第一連桿48的第二端54係通過第三連桿58連結到第二連桿50。藉由第三連桿58之設計，第二連桿50可隨著第一連桿48的旋轉而沿著第一方向D1來回線性移動。The link group 22 may include a first link 48 and a second link 50. The first end 52 of the first link 48 is connected to the slider 38, and the second end 54 is connected to the lift button 14 via the second link 50. The turning end 56 of the first link 48 is located between the first end 52 and the second end 54 for pivotally connecting the first connecting member 20. Therefore, the movement of the sliding tip 38 in the sliding groove 42 will pull the first link 48 to rotate around the turning end 56 as the axis, thereby driving the displacement of the second link 50. In the preferred embodiment of the present invention, the link group 22 may further include a third link 58. The second end 54 of the first link 48 is connected to the second link 50 by a third link 58. With the design of the third link 58, the second link 50 can linearly move back and forth along the first direction D1 as the first link 48 rotates.

第二彈性元件60為選擇性配置元件。第二彈性元件60的兩端分別連接第一連桿48與第一連接件20。第一凸輪34從突出部44滑向平坦部46時，不僅第一彈性元件28的彈性恢復力可驅動支撐件24沿著第一轉軸16往橋接件18的方向移動，第二彈性元件60也能釋放其彈性恢復力，帶動連桿組22的第一連桿48相對第一連接件20產生順時針旋轉，同樣可提供支撐件24回復到初始位置。The second elastic element 60 is a selective configuration element. The two ends of the second elastic element 60 are respectively connected to the first link 48 and the first connector 20. When the first cam 34 slides from the protruding portion 44 to the flat portion 46, not only the elastic restoring force of the first elastic element 28 can drive the support member 24 to move along the first rotating shaft 16 in the direction of the bridge member 18, but also the second elastic element 60 It can release its elastic restoring force, driving the first link 48 of the link group 22 to rotate clockwise relative to the first link 20, and also can provide the support 24 to return to the initial position.

樞軸機構12還可包含第一樞紐件62、第二樞紐件64、第三樞紐件66以及扭力元件68。第一樞紐件62連結第一轉軸16，第二樞紐件64連結第二轉軸30。扭力元件68設置在第一樞紐件62與第二樞紐件64上。扭力元件68之數量與位置不限於本發明實施例所示，端視扭力調節需求而定。第三樞紐件66位於第一樞紐件62和第二樞紐件64之間。第一樞紐件62的第一主動件70配合第三樞紐件66的第二主動件72，第二樞紐件64的第一被動件74配合第三樞紐件66的第二被動件76。此外，樞軸機構12可包含外殼78，用來包覆在樞紐組(意即第一樞紐件62、第二樞紐件64與第三樞紐件66)以及扭力元件68外以提供防塵保護。The pivot mechanism 12 may further include a first hinge member 62, a second hinge member 64, a third hinge member 66, and a torsion element 68. The first hinge member 62 is connected to the first rotating shaft 16, and the second hinge member 64 is connected to the second rotating shaft 30. The torsion element 68 is disposed on the first hinge member 62 and the second hinge member 64. The number and position of the torque elements 68 are not limited to those shown in the embodiments of the present invention, and depend on the torque adjustment requirements. The third hinge piece 66 is located between the first hinge piece 62 and the second hinge piece 64. The first active member 70 of the first hinge member 62 cooperates with the second active member 72 of the third hinge member 66, and the first passive member 74 of the second hinge member 64 cooperates with the second passive member 76 of the third hinge member 66. In addition, the pivot mechanism 12 may include a housing 78 for covering the pivot group (meaning the first pivot member 62, the second pivot member 64, and the third pivot member 66) and the torsion element 68 to provide dust protection.

請參閱第5圖，第5圖為本發明實施例之移除外殼78之樞軸機構12之示意圖。樞軸機構12在翻轉時，第一主動件70與第二主動件72因機械配合而彼此反向旋轉，第一被動件74與第二被動件76之間的配合不會發生干涉，故第二轉軸30可通過橋接件18與樞紐組環繞第一轉軸16旋轉，使得第一殼體B能順暢地相對第二殼體C展開或收合。一般來說，第二轉軸30相對第一轉軸16的旋轉角度係小於三百六十度，讓電控裝置能從筆電模式切換為平板模式；然實際應用當不限於此。Please refer to FIG. 5, which is a schematic diagram of the pivot mechanism 12 with the housing 78 removed according to an embodiment of the invention. When the pivot mechanism 12 is turned over, the first active member 70 and the second active member 72 rotate reversely due to mechanical cooperation, and the cooperation between the first passive member 74 and the second passive member 76 does not interfere, so the first The second rotating shaft 30 can rotate around the first rotating shaft 16 through the bridge 18 and the hinge group, so that the first housing B can smoothly expand or collapse relative to the second housing C. Generally speaking, the rotation angle of the second rotating shaft 30 relative to the first rotating shaft 16 is less than 360 degrees, so that the electronic control device can be switched from the laptop mode to the tablet mode; however, the actual application is not limited to this.

請參閱第6圖至第11圖，第6圖與第7圖分別為本發明實施例之第一凸輪34與第二凸輪40在不同操作階段之示意圖，第8圖為本發明實施例之連桿組22處於第一狀態之示意圖，第9圖為本發明實施例之連桿組22處於第二狀態之示意圖，第10圖為第8圖所示之連桿組22於另一視角之示意圖，第11圖為第9圖所示之連桿組22於另一視角之示意圖。Please refer to FIG. 6 to FIG. 11, FIG. 6 and FIG. 7 are schematic diagrams of the first cam 34 and the second cam 40 in different operation stages of the embodiment of the present invention, and FIG. 8 is a continuous diagram of the embodiment of the present invention. The schematic diagram of the rod group 22 in the first state, FIG. 9 is a schematic diagram of the connecting rod group 22 in the second state according to an embodiment of the present invention, and FIG. 10 is a schematic diagram of the connecting rod group 22 shown in FIG. 8 from another perspective FIG. 11 is a schematic view of the connecting rod group 22 shown in FIG. 9 from another perspective.

如第6圖所示，第一殼體B為靠近第二殼體C的狀態，此時橋接件18位於第一角度，支撐件24位於第一位置；第一凸輪34抵靠於第二凸輪40的平坦部46，此時第一彈性元件28沒有被擠壓。如第7圖所示，第一殼體B相對於第二殼體C翻轉約九十度至一百八十度之範圍內，橋接件18位於第二角度，第一凸輪34沿著第一轉軸16旋轉，並從平坦部46滑動至突出部44。其中，第一殼體B相對第二殼體C的翻轉角度並不限於前揭實施態樣所示，端視設計需求而定。第二凸輪40受到第一凸輪34之軌跡會造成支撐件24沿著第一轉軸16左移至第二位置，使得第一彈性元件28產生壓縮變形。若第一殼體B的翻轉角度超出一百八十度、或收回而小於九十度，第一凸輪34將從突出部44移回平坦部46，第一彈性元件28所儲存的彈性恢復力被釋放，提供支撐件24沿著第一轉軸16右移，以回到第6圖所示之第一位置。As shown in FIG. 6, the first housing B is close to the second housing C. At this time, the bridge 18 is at the first angle, and the support 24 is at the first position; the first cam 34 abuts the second cam The flat portion 46 of 40, at this time, the first elastic element 28 is not pressed. As shown in FIG. 7, the first housing B is turned over about 90 degrees to 180 degrees relative to the second housing C, the bridge 18 is located at the second angle, and the first cam 34 is along the first The rotating shaft 16 rotates and slides from the flat portion 46 to the protruding portion 44. Wherein, the turning angle of the first housing B relative to the second housing C is not limited to that shown in the foregoing embodiment, and depends on the design requirements. The trajectory of the first cam 34 caused by the second cam 40 causes the support member 24 to move to the second position along the first rotation axis 16 to the left, so that the first elastic element 28 is compressed and deformed. If the turning angle of the first housing B exceeds one hundred and eighty degrees, or retracts to less than ninety degrees, the first cam 34 will move from the protrusion 44 back to the flat portion 46, and the elastic restoring force stored by the first elastic element 28 After being released, the supporting member 24 is provided to move right along the first rotating shaft 16 to return to the first position shown in FIG. 6.

如第8圖與第10圖所示，第一凸輪34接觸第二凸輪40的平坦部46，第一連桿48的第一端52連結滑梢38並位於滑槽42的右端，連桿組22處於第一狀態，此時第二彈性元件60沒有受到擠壓。如第9圖與第11圖所示，第一凸輪34觸及第二凸輪40的突出部44，支撐件24沿著第一轉軸16左移，使滑梢38從滑槽42的右端移向左端。此時，第一連桿48以轉折端56為軸心相對第一連接件20發生逆時針旋轉，第二彈性元件60受擠壓儲存彈性恢復力。第三連桿58受到第一連桿48之牽引發生順時針轉動，從而推動第二連桿50沿著第一方向D1平移，連桿組22切換到第二狀態。第二連桿50的線性移動可用來調整升降式按鍵14之高度，使其自第二殼體C抬昇，供使用者操作。As shown in FIGS. 8 and 10, the first cam 34 contacts the flat portion 46 of the second cam 40, and the first end 52 of the first link 48 is connected to the sliding tip 38 and is located at the right end of the sliding slot 42. 22 is in the first state, at which time the second elastic element 60 is not compressed. As shown in FIGS. 9 and 11, the first cam 34 touches the protruding portion 44 of the second cam 40, and the support 24 moves to the left along the first rotating shaft 16, so that the slider 38 moves from the right end to the left end of the slide slot 42 . At this time, the first link 48 rotates counterclockwise with respect to the first connecting member 20 with the turning end 56 as the axis, and the second elastic element 60 is compressed to store the elastic restoring force. The third link 58 is pulled clockwise by the first link 48 to rotate clockwise, thereby pushing the second link 50 to translate in the first direction D1, and the link group 22 is switched to the second state. The linear movement of the second link 50 can be used to adjust the height of the lifting button 14 to lift it from the second housing C for the user to operate.

如第一殼體B的翻轉角度超出一百八十度、或收回而小於九十度，第一彈性元件28的彈性恢復力驅動支撐件24沿著第一轉軸16右移，可帶動滑梢38從滑槽42的左端移回右端，讓連桿組22切回第一狀態。除此之外，第二彈性元件60的彈性恢復力也會推動第一連桿48以轉折端56為軸心產生順時針旋轉，有助於將連桿組22切回第一狀態，可使第二連桿50反向收回，降低升降式按鍵14的高度以收入第二殼體C內。If the turning angle of the first housing B exceeds one hundred eighty degrees, or retracts to less than ninety degrees, the elastic restoring force of the first elastic element 28 drives the support 24 to move to the right along the first rotating shaft 16 and can drive the slider 38 moves from the left end of the chute 42 back to the right end, allowing the link group 22 to switch back to the first state. In addition, the elastic restoring force of the second elastic element 60 will also push the first link 48 to rotate clockwise with the turning end 56 as the axis, which helps to cut the link group 22 back to the first state, so that The two connecting rods 50 are retracted in the reverse direction, and the height of the lifting button 14 is reduced to be received in the second housing C.

FIG. 16 is a schematic diagram of the electronic control device A according to the first embodiment of the present invention, and FIG. 17 is a schematic diagram of the height adjusting mechanism 80 according to the first embodiment of the present invention. The height adjustment mechanism 80 may include a base 82, a first link 84, a second link 86 and a motor 88. The first link 84 is movably disposed on the base 82 and used to connect to the lifting button 14. The second link 86 is electrically connected to the motor 88, and is combined with the first link 84 in a relatively movable manner. The motor 88 drives the second link 86 to rotate, and the first link 84 can be pulled to be displaced relative to the base 82. The height adjustment mechanism 80 may further include a sensor 90 and an arithmetic processor 92. The arithmetic processor 92 provides signals to the motor 88 and the sensor 90 to cooperate with each other. The sensor 90 can detect the relative movement of the first housing B and the second housing C by optical or electromagnetic effects. The arithmetic processor 92 determines whether the motor 88 is triggered to adjust the height of the lifting button 14 according to the sensing result of the sensor 90.

如第17圖所示，第一連動件84具有條狀溝槽94，第二連動件86具有條狀卡合部96。條狀卡合部96係配合條狀溝槽94。第二連動件86進行自轉時，條狀卡合部96推擠條狀溝槽94的內壁面，讓第一連動件84在底座82的容置空間內單向移動。移動的第一連動件84能用來牽引升降式按鍵14的致動元件，讓升降式按鍵14在第二殼體C上抬昇或降低高度。換句話說，第一殼體B相對第二殼體C翻轉時，感測器90”偵測”到第一殼體B遠離第二殼體C，運算處理器92即能據以啟動馬達88，將升降式按鍵14調整到適當高度。As shown in FIG. 17, the first link 84 has a strip-shaped groove 94, and the second link 86 has a strip-shaped engaging portion 96.

When the second link 86 rotates, the strip-shaped engaging portion 96 pushes the inner wall surface of the strip-shaped groove 94 to allow the first link 84 to move unidirectionally in the accommodating space of the base 82. The moving first linking member 84 can be used to pull the actuating element of the lifting button 14 to allow the lifting button 14 to raise or lower the height on the second housing C. In other words, when the first housing B is turned over with respect to the second housing C, the sensor 90 "detects" that the first housing B is away from the second housing C, and the arithmetic processor 92 can accordingly start the motor 88 , Adjust the lifting button 14 to an appropriate height.

The figure is an assembly diagram of a height adjustment mechanism 80' according to a second embodiment of the invention. The first link 84' of the height adjustment mechanism 80' has a locus 98, and the second link 86' has a flange portion 100, and the flange portion 100 slides along the locus 98. The trajectory 98 is a curve that follows the functional requirements, as shown by the broken line pattern in FIG. 19. The second link member 86' is rotatably provided on the axis 102. When the second link member 86' is driven to rotate, causing the flange portion 100 to slide from the concave portion of the track 98 to the convex portion, the first link member 84' is squeezed and translates to the left relative to the base 82' along the axis 102 . The moving first link member 84' can pull the lifting button 14 to raise or lower the height in the second housing C.

除此之外，軸心102還可具有限位部104，用來卡合於第二連動件86’的限位槽106。運算處理器92可根據感測器90的感測結果，驅動馬達88’旋轉第二連動件86’，以牽引第一連動件84’並帶動升降式按鍵14的高度調整機制。若是軸心102的限位部104***限位槽106，即能用來限制第二連動件86’相對軸心102之旋轉。高度調整機構80’可以移動軸心102、或是移動第二連動件86’、或是同時移動軸心102與第二連動件86’，進行限位部104及限位槽106的卡合與分離；其致發機制可為人工手動或系統自行驅動，端視實際需求而定。In addition, the axis 102 may also have a limiting portion 104 for engaging with the limiting groove 106 of the second link 86'. The arithmetic processor 92 can drive the motor 88' to rotate the second link member 86' according to the sensing result of the sensor 90, so as to pull the first link member 84' and drive the height adjustment mechanism of the lifting button 14. If the limiting portion 104 of the shaft 102 is inserted into the limiting groove 106, it can be used to limit the rotation of the second link member 86' relative to the shaft 102. The height adjustment mechanism 80' can move the axis 102, or move the second link 86', or move the axis 102 and the second link 86' at the same time to engage and engage the limiting portion 104 and the limiting groove 106 Separation; the triggering mechanism can be manually driven or driven by the system, depending on the actual needs.
