Description
一種防抖動之指針驅動裝置，尤指用於驅動指針旋動並防止指針產生抖動之驅動裝置。An anti-jitter pointer driving device, especially a driving device for driving a pointer to rotate and preventing a pointer from being shaken.
按，儀錶之指針係利用驅動裝置所設置之轉軸連接並利用步進馬達作為驅動動力，使轉軸於旋動時可帶動指針指示出相關位置，而習用指針於進行歸零指示時，係利用轉軸之止擋方式讓指針於歸零時碰觸停止，然而，當指針碰觸後準備停止的瞬間，因步進馬達所提供之動力無法即刻停止，俾使該殘餘之動力係會讓轉軸驅動指針產生微微抖動，因此，該習知結構讓指針於歸零指示時，會讓指針因步進馬達之殘留動力產生抖動，使指針無法正確的指示出歸零位置。Pressing, the pointer of the meter is connected by the rotating shaft provided by the driving device and using the stepping motor as the driving power, so that the rotating shaft can drive the pointer to indicate the relevant position when the rotating shaft is rotated, and the conventional pointer uses the rotating shaft when performing the zeroing indication. The stop mode allows the pointer to stop when it is reset to zero. However, when the pointer is ready to stop after the touch, the power provided by the stepping motor cannot be stopped immediately, so that the residual power will cause the spindle to drive the pointer. The slight jitter is generated. Therefore, the conventional structure allows the pointer to be shaken by the residual power of the stepping motor when the pointer is turned to zero, so that the pointer cannot correctly indicate the return to zero position.
是以，要如何解決上述習知之問題與缺失，即為相關業者所亟欲研發之課題。Therefore, how to solve the above-mentioned problems and shortcomings is the subject of research and development that the relevant industry is eager to develop.
本發明之主要目的乃在於，利用一位移距離用以供步進馬達的殘餘動力來產生緩衝空間，讓指針於碰觸後即刻停止，而被步進馬達帶動之傳動件可於該位移距離內形成緩衝而不影響指針的停止狀態。The main purpose of the present invention is to use a displacement distance for the residual power of the stepping motor to generate a buffer space, so that the pointer stops immediately after the touch, and the transmission member driven by the stepping motor can be within the displacement distance. The buffer is formed without affecting the stop state of the pointer.
為達上述目的，本發明防抖動之指針驅動裝置係設置有具指針之指示件、傳動組及驅動器，該傳動組係設置有連接於驅動器之第一傳動件、及連接於指針之第二傳動件，第二傳動件係位於第一傳動件上方，且第一傳動件與第二傳動件係利用有樞軸形成 樞接旋動，而第一傳動件表面凸設有傳動柱，第二傳動件表面設置有長形之傳動孔，傳動柱係位於傳動孔；當指針於歸零指示時係會於碰觸後即刻停止，而驅動器所產生之殘餘動力係會帶動傳動柱於傳動孔內產生位移，藉由傳動柱於傳動孔內位移使指針不受驅動器殘留動力的影響，達到防止指針抖動之現象。In order to achieve the above object, the anti-jitter pointer driving device of the present invention is provided with an indicator with a pointer, a transmission group and a driver, the transmission group being provided with a first transmission member connected to the driver and a second connected to the pointer a transmission member, the second transmission member is located above the first transmission member, and the first transmission member and the second transmission member are formed by pivoting The pivoting of the first transmission member is convexly disposed on the surface of the first transmission member, and the surface of the second transmission member is provided with an elongated transmission hole, and the transmission column is located in the transmission hole; when the pointer is returned to the zero indication, the contact is after the touch Immediately stop, and the residual power generated by the driver will drive the transmission column to generate displacement in the transmission hole. The displacement of the transmission column in the transmission hole prevents the pointer from being affected by the residual power of the driver, thereby preventing the pointer from shaking.

A second transmission member 224 is disposed, and the second transmission member 22 is disposed above the first transmission member 21, and the transmission post 211 of the first transmission member 21 is located in the transmission hole 221 of the second transmission member 22, and A transmission member 21 and a second transmission member 22 are pivotally connected to the pivot shaft 23 to form a rotation.
該驅動器3係具有第二旋動件31，第二旋動件31外周緣係設置有第四傳動齒311，且第二旋動件31一側連接有步進馬達32。The driver 3 has a second rotating member 31. The second rotating member 31 is provided with a fourth driving tooth 311 on the outer circumference thereof, and a stepping motor 32 is connected to one side of the second rotating member 31.
藉上，當本發明於組構時，係將指示件1第一旋動件11之第一傳動齒111連接於傳動組2第二傳動件22之第二傳動齒224，用以讓第二傳動件22連接於指示件1之指針12藉由第一傳動齒 111及第二傳動齒224形成連接樞動，而傳動組2第一傳動件21之第三傳動齒212係連接於驅動器3之第二旋動件31的第四傳動齒311，使第一傳動件21與第二旋動件31形成樞動，俾讓第一傳動件21之傳動柱211被驅動後會推動第二傳動件22之傳動孔221而產生位移動作。By the way, when the present invention is configured, the first transmission tooth 111 of the first rotating member 11 of the indicator member 1 is connected to the second transmission tooth 224 of the second transmission member 22 of the transmission group 2 for the second The transmission member 22 is connected to the pointer 12 of the indicator 1 by the first transmission tooth 111 and the second transmission tooth 224 form a connection pivoting, and the third transmission tooth 212 of the first transmission member 21 of the transmission group 2 is connected to the fourth transmission tooth 311 of the second rotation member 31 of the driver 3, so that the first transmission The member 21 is pivoted with the second rotating member 31, so that the transmission post 211 of the first transmission member 21 is driven to push the transmission hole 221 of the second transmission member 22 to generate a displacement action.
請參閱第四圖及第五圖所示，當本發明裝設於儀錶板5內並開始使用時，該驅動器3之步進馬達32係會啟動第二旋動件31旋動，使第二旋動件31之第四傳動齒311帶動傳動組2之第一傳動件21藉由第三傳動齒212產生逆時針旋動，俾使第一傳動件21之傳動柱211會抵持於第二傳動件22之傳動孔221的第二抵靠端223，同時藉由傳動柱211推動傳動孔221之第二抵靠端223產生順時針旋動，帶動第二傳動件22之第二傳動齒224嚙合於第一旋動件11之第一傳動齒111，讓第一旋動件11產生逆時針旋動，用以帶動指針12進行歸零指示；如第五圖所示，當指針12接收歸零指示時會產生碰觸停止，使第一旋動件11之第一傳動齒111停止與第二傳動件22之第二傳動齒224的旋動嚙合動作，此時，驅動器3之步進馬達32尚未完全停止動作而產生殘留動力，俾使步進馬達32會帶動第二旋動件31稍微旋動，讓第二旋動件31之第四傳動齒311會帶動第一傳動件21微微旋動，此時，第一傳動件21之傳動柱211係會脫離與第二傳動件22傳動孔221之第二抵靠端223進而產生位移，因此，藉由該長形之傳動孔221可供殘留有動力之傳動柱211產生緩衝的位移段，藉以讓指針12不受步進馬達32的影響，而達到防止指針12歸零指示時所產生之抖動現象，讓本發明於使用時更能讓指針12穩定歸零而不產生誤差。Referring to the fourth and fifth figures, when the present invention is installed in the instrument panel 5 and starts to be used, the stepping motor 32 of the driver 3 activates the second rotating member 31 to rotate, so that the second The fourth transmission tooth 311 of the rotating member 31 drives the first transmission member 21 of the transmission group 2 to rotate counterclockwise by the third transmission tooth 212, so that the transmission post 211 of the first transmission member 21 will resist the second The second abutting end 223 of the transmission hole 221 of the transmission member 22, while the second abutting end 223 of the transmission hole 221 is driven by the transmission post 211 to generate a clockwise rotation, and the second transmission tooth 224 of the second transmission member 22 is driven. Engaged in the first driving tooth 111 of the first rotating member 11, the first rotating member 11 is rotated counterclockwise to drive the pointer 12 to perform a zeroing indication; as shown in the fifth figure, when the pointer 12 receives the return When the zero indication is made, the touch stop is generated, so that the first transmission tooth 111 of the first rotating member 11 stops the rotational engagement with the second transmission tooth 224 of the second transmission member 22, and at this time, the stepping motor of the driver 3 32 has not completely stopped the action to generate residual power, so that the stepping motor 32 will drive the second rotating member 31 to slightly rotate, so that The fourth transmission tooth 311 of the rotating member 31 can drive the first transmission member 21 to slightly rotate. At this time, the transmission post 211 of the first transmission member 21 is disengaged from the second abutment of the transmission hole 221 of the second transmission member 22. The end 223 is further displaced, so that the elongated transmission hole 221 can be used to generate a buffered displacement section of the residual power transmission post 211, thereby preventing the pointer 12 from being affected by the stepping motor 32 and preventing the pointer 12 from being formed. The jitter phenomenon generated when the zero indication is made allows the present invention to more stably return the pointer 12 to zero without error.
請參閱第六圖至第八圖所示，由圖中可清楚看出本發明之第二實施例，第二實施例與第一實施例之不同處在於，該傳動組4係設置有第一傳動件41、第二傳動件42及樞軸43，第一傳動件41表面設置有長形之傳動孔411，及其外周緣係設置有第三傳動齒412，而第二傳動件42表面凸設有傳動柱421，及於第二傳動件42遠離第一傳動件41另側設置有第二傳動齒422，而第二傳動件42係設置於第一傳動件41上方，且第二傳動件42之傳動柱421係位於第一傳動件41之傳動孔411內，並使第一傳動件41與第二傳動件42均樞接於該樞軸43形成旋動；當第二實施例於組構時係將第一旋動件11之第一傳動齒111連接於傳動組4之第二傳動件42的第二傳動齒422而形成旋動，而傳動組4第一傳動件41之第三傳動齒412係連接於驅動器3第二旋動件31之第四傳動齒311而形成旋動，俾使第一傳動件41之傳動孔411被驅動後會推動第二傳動件42之傳動柱421而產生位移動作。Referring to the sixth to eighth embodiments, the second embodiment of the present invention is clearly seen from the drawings. The second embodiment is different from the first embodiment in that the transmission group 4 is provided with the first The transmission member 41, the second transmission member 42 and the pivot shaft 43 are provided with an elongated transmission hole 411 on the surface of the first transmission member 41, and a third transmission tooth 412 is disposed on the outer periphery thereof, and the second transmission member 42 is convex on the surface. The transmission post 421 is disposed, and the second transmission member 42 is disposed on the other side of the second transmission member 42 away from the first transmission member 41, and the second transmission member 42 is disposed above the first transmission member 41, and the second transmission member is disposed. The transmission post 421 of the 42 is located in the transmission hole 411 of the first transmission member 41, and the first transmission member 41 and the second transmission member 42 are pivotally connected to the pivot shaft 43 to form a rotation; when the second embodiment is in the group The first transmission tooth 111 of the first rotating member 11 is connected to the second transmission tooth 422 of the second transmission member 42 of the transmission group 4 to form a rotation, and the third transmission member 41 of the transmission group 4 is third. The transmission tooth 412 is connected to the fourth transmission tooth 311 of the second rotating member 31 of the driver 3 to form a rotation, and the transmission hole 411 of the first transmission member 41 is caused. It will push the second transmission gear member after column 42,142 displaced driving operation.
藉上，當第二實施例之指針12接收歸零指示時，因指針12碰觸停止，使第一旋動件11停止旋動，及傳動組4之第二傳動件42係藉由第一旋動件11而停止旋動，同時，驅動器3之步進馬達32的殘餘動力係讓傳動組4之第一傳動件41產生稍微旋動，俾讓第一傳動件41之傳動孔411會依第二傳動件42之傳動柱421產生位移，用以抵消步進馬達32的殘餘動力而產生緩衝作用，有效防止指針12於歸零指示時所產生之抖動現象，讓本發明於使用時更能讓指針12穩定歸零而不產生誤差。By the way, when the pointer 12 of the second embodiment receives the return-to-zero indication, the first rotating member 11 stops rotating due to the stop of the pointer 12, and the second transmission member 42 of the transmission set 4 is first The rotary member 11 stops rotating, and at the same time, the residual power of the stepping motor 32 of the driver 3 causes the first transmission member 41 of the transmission group 4 to be slightly rotated, so that the transmission hole 411 of the first transmission member 41 is adjusted. The transmission post 421 of the second transmission member 42 is displaced to cancel the residual power of the stepping motor 32 to generate a buffering effect, thereby effectively preventing the jitter phenomenon generated when the pointer 12 is returned to the zero indication, so that the present invention can be more used during use. Let pointer 12 settle to zero without error.
