Description

固定模組、投影鏡頭組件及投影機Fixed module, projection lens assembly and projector

本創作是有關於一種固定模組、投影鏡頭組件及投影機。This creation is about a fixed module, projection lens assembly and projector.

目前，商務型/家庭劇院投影機於使用時會將投影鏡頭依據實際環境做焦距與畫面大小的調整，使其投影畫面達最佳觀看品質。具體來說，投影機的投影鏡頭模組於設計時，一般都會有兩個調整環作為畫面調整用，一為畫面焦距的調整，一為畫面大小的調整。At present, business type/home theater projectors will adjust the focal length and screen size of the projection lens according to the actual environment to make the projection screen reach the best viewing quality. Specifically, during the design of the projection lens module of the projector, two adjustment rings are generally used for image adjustment, one for adjusting the focal length of the image, and the other for adjusting the image size.

然而，若兩個調整環的預設調整扭力過小時，容易因突來的外力而使調好的畫面跑掉、失真。此時，使用者必須針對失真的畫面再度重新調整。另外，或許有些設計會安裝電動減速馬達模組來帶動調整環做畫面的調整，但這需投入較多的開發人力與較高的成本。再者，在使用電動減速馬達模組做畫面調整的同時，也會因為電動減速馬達模組的作動而產生噪音。However, if the preset adjustment torque of the two adjustment rings is too small, the adjusted picture will easily run off and be distorted due to sudden external forces. At this time, the user must readjust again for the distorted picture. In addition, some designs may install electric deceleration motor modules to drive the adjustment ring to adjust the screen, but this requires more development manpower and higher costs. Furthermore, when the electric deceleration motor module is used for screen adjustment, noise will also be generated due to the action of the electric deceleration motor module.

因此，提出一種可解決上述問題的固定模組、投影鏡頭組件及投影機，是目前業界亟欲投入研發資源解決的問題之一。Therefore, to propose a fixed module, projection lens assembly and projector that can solve the above-mentioned problems is one of the problems that the industry urgently wants to invest in research and development resources to solve.

於一些實施方式中，鏡頭模組122可以僅包含兩調整環122a、122b的其中一者。舉例來說，鏡頭模組122可以僅包含調整環122b，在使用這種投影機100時，使用者需先調整投影機100的放置位置以投射出想要的投影畫面大小，再藉由轉動調整環122b調整投影畫面的焦距。In some embodiments, the lens module 122 may include only one of the two adjustment rings 122a and 122b. For example, the lens module 122 may only include the adjustment ring 122b. When using this projector 100, the user needs to adjust the placement position of the projector 100 to project the desired projection screen size, and then adjust it by rotating The ring 122b adjusts the focal length of the projected image.

請參照第3圖、第4圖以及第5圖。第3圖為繪示第2A圖中之投影鏡頭組件120沿著割面線3-3的局部剖面圖。第4圖為繪示第3圖中之投影鏡頭組件120的另一局部剖面圖。第5圖為繪示第2B圖中之固定模組200沿著割面線5-5的剖面圖。如第3圖至第5圖所示，兩調整環122a、122b位於一位置，且分別具有第一結合部122a1、122b1。固定模組200包含殼體210、驅動件220以及移動件230。殼體210固定至投影鏡頭組件120的基座121。驅動件220可轉動地設置於殼體210，並配置以第二軸線A2為中心轉動。於一些實施方式中，第二軸線A2與第一軸線A1相互垂直。移動件230與驅動件220銜接，且具有第二結合部232。當移動件230受轉動之驅動件220所驅動而遠離殼體210移動到達兩調整環122a、122b所在的前述位置時，兩調整環122a、122b的第一結合部122a1、122b1與移動件230的第二結合部232結合。當移動件230受轉動之驅動件220所驅動而朝向殼體210移動時，第二結合部232釋放第一結合部122a1、122b1。Please refer to Figure 3, Figure 4 and Figure 5. FIG. 3 is a partial cross-sectional view of the projection lens assembly 120 in FIG. 2A along the cutting plane line 3-3. FIG. 4 is another partial cross-sectional view of the projection lens assembly 120 shown in FIG. 3. FIG. Fig. 5 is a cross-sectional view of the fixing module 200 in Fig. 2B along the cutting plane line 5-5. As shown in FIGS. 3 to 5, the two adjusting rings 122a, 122b are located at one position, and have first coupling portions 122a1, 122b1, respectively. The fixed module 200 includes a housing 210, a driving part 220 and a moving part 230. The housing 210 is fixed to the base 121 of the projection lens assembly 120. The driving member 220 is rotatably disposed on the housing 210 and is configured to rotate around the second axis A2. In some embodiments, the second axis A2 and the first axis A1 are perpendicular to each other. The moving part 230 is connected to the driving part 220 and has a second coupling part 232. When the moving part 230 is driven by the rotating driving part 220 and moves away from the housing 210 to the aforementioned position where the two adjusting rings 122a, 122b are located, the first coupling portion 122a1, 122b1 of the two adjusting rings 122a, 122b and the moving part 230 The second coupling part 232 is coupled. When the moving member 230 is driven by the rotating driving member 220 to move toward the housing 210, the second coupling portion 232 releases the first coupling portions 122a1, 122b1.

基於前述結構配置，在兩調整環122a、122b被調整至定位之後，藉由使固定模組200的驅動件220相對於殼體210轉動，即可驅使移動件230同時壓抵固定兩調整環122a、122b，進而可有效地解決因突來的外力而使調好的畫面跑掉、失真的問題。Based on the aforementioned structural configuration, after the two adjusting rings 122a and 122b are adjusted to be positioned, by rotating the driving member 220 of the fixed module 200 relative to the housing 210, the moving member 230 can be driven to press and fix the two adjusting rings 122a at the same time. , 122b, which can effectively solve the problem of running off and distorting the adjusted picture due to sudden external force.

於一些實施方式中，如第2A圖、第2B圖、第3圖、第4圖和第5圖所示，固定模組200的殼體210包含容置槽211以及延伸部212。容置槽211位於兩調整環122a、122b上方。延伸部212位於容置槽211外，並固定至投影鏡頭組件120的基座121（例如，藉由螺絲鎖固）。容置槽211配置以容置移動件230，可用以確保移動件230的移動方向與行程，並可保護移動件230。In some embodiments, as shown in FIG. 2A, FIG. 2B, FIG. 3, FIG. 4, and FIG. 5, the housing 210 of the fixed module 200 includes an accommodation groove 211 and an extension 212. The accommodating groove 211 is located above the two adjusting rings 122a, 122b. The extension 212 is located outside the accommodating groove 211 and is fixed to the base 121 of the projection lens assembly 120 (for example, it is locked by screws). The accommodating groove 211 is configured to accommodate the moving part 230, which can ensure the moving direction and stroke of the moving part 230 and protect the moving part 230.

於一些實施方式中，如第3圖至第5圖所示，容置槽211具有穿孔211a。驅動件220可轉動地銜接穿孔211a。具體來說，驅動件220包含樞接部221、操作部222以及銜接部223。樞接部221樞接於穿孔211a。操作部222連接樞接部221的一端。銜接部223連接樞接部221的另一端，並與移動件230銜接。操作部222與銜接部223分別位於殼體210的相反兩側。亦即，操作部222位於容置槽211外，而銜接部223位於容置槽211內。操作部222可設計成具有類似於撥片的外型，以適於使用者轉動。In some embodiments, as shown in FIGS. 3 to 5, the receiving groove 211 has a through hole 211a. The driving member 220 rotatably engages the through hole 211a. Specifically, the driving member 220 includes a pivoting portion 221, an operating portion 222 and a connecting portion 223. The pivotal portion 221 is pivotally connected to the through hole 211a. The operating portion 222 is connected to one end of the pivoting portion 221. The connecting portion 223 is connected to the other end of the pivoting portion 221 and is connected with the moving part 230. The operating portion 222 and the connecting portion 223 are respectively located on opposite sides of the housing 210. That is, the operating portion 222 is located outside the accommodating groove 211, and the connecting portion 223 is located in the accommodating groove 211. The operating portion 222 may be designed to have an appearance similar to a paddle so as to be suitable for rotation by the user.

於一些實施方式中，如第3圖所示，操作部222與銜接部223的寬度皆大於穿孔211a的寬度，使得殼體210的一部分限位於操作部222與銜接部223之間。藉此，驅動件220即可相對於殼體210自轉而不脫離。In some embodiments, as shown in FIG. 3, the widths of the operating portion 222 and the connecting portion 223 are both greater than the width of the through hole 211 a, so that a part of the housing 210 is limited between the operating portion 222 and the connecting portion 223. Thereby, the driving member 220 can rotate relative to the housing 210 without being separated.

於一些實施方式中，移動件230的第二結合部232包含彈性材料，並配置以壓抵兩調整環122a、122b。藉此，第二結合部可彌補兩調整環122a、122b之間的組裝公差，進而可達到更好的固定效果。In some embodiments, the second coupling portion 232 of the moving element 230 includes an elastic material and is configured to press against the two adjusting rings 122a and 122b. In this way, the second coupling portion can compensate for the assembly tolerance between the two adjusting rings 122a and 122b, thereby achieving a better fixing effect.

於一些實施方式中，如第5圖所示，移動件230包含固持部231。固持部231與驅動件220銜接，並固持第二結合部232。固持部231的硬度大於第二結合部232的硬度。具體來說，固持部231包含固持槽231a。第二結合部232係卡合於固持槽231a內。於一些實施方式中，第二結合部232可進一步黏合於固持槽231a內。In some embodiments, as shown in FIG. 5, the moving element 230 includes a holding portion 231. The holding portion 231 is connected to the driving member 220 and holds the second joining portion 232. The hardness of the holding portion 231 is greater than the hardness of the second coupling portion 232. Specifically, the holding portion 231 includes a holding groove 231a. The second coupling portion 232 is engaged in the holding groove 231a. In some embodiments, the second coupling portion 232 may be further bonded in the holding groove 231a.

於一些實施方式中，如第5圖所示，固持部231進一步包含導孔柱231c。導孔柱231c於固持槽231a內連接於固持槽231a的底部，並連通固持槽231a的內外空間。導孔柱231c穿入第二結合部232，以增加固持部231與第二結合部232之間的接觸面積，進而使得固持部231與第二結合部232更好地相互固定。另外，固定模組200的殼體210還進一步包含導引銷213。導引銷213於容置槽211內連接容置槽211的底部，並沿著第二軸線A2延伸。導引銷213係可滑動地穿設於導孔柱231c，藉以在移動件230受驅動件220驅動時導引移動件230，並避免移動件230繞著第二軸線A2轉動而無法上升與下降。In some embodiments, as shown in FIG. 5, the holding portion 231 further includes a via post 231c. The guide hole post 231c is connected to the bottom of the holding groove 231a in the holding groove 231a, and communicates with the inner and outer spaces of the holding groove 231a. The via post 231c penetrates into the second coupling portion 232 to increase the contact area between the holding portion 231 and the second coupling portion 232, so that the holding portion 231 and the second coupling portion 232 are better fixed to each other. In addition, the housing 210 of the fixed module 200 further includes a guide pin 213. The guide pin 213 is connected to the bottom of the containing groove 211 in the containing groove 211 and extends along the second axis A2. The guide pin 213 is slidably penetrated through the guide hole post 231c, so as to guide the moving part 230 when the moving part 230 is driven by the driving part 220, and prevent the moving part 230 from rotating around the second axis A2 and unable to rise and fall .

於一些實施方式中，如第3圖至第5圖所示，驅動件220的銜接部223具有第一螺紋結構223a。移動件230具有第二螺紋結構231b。第一螺紋結構223a與第二螺紋結構231b相螺合。轉動之驅動件220係透過第一螺紋結構223a相對於第二螺紋結構231b滑動而驅動移動件230移動。藉此，當使用者以一旋轉方向（例如，順時針方向）轉動驅動件220時，轉動之驅動件220可使得移動件230沿著第二軸線A2下降並壓抵固定兩調整環122a、122b（如第4圖所示）；當使用者以另一旋轉方向（例如，逆時針方向）轉動驅動件220時，轉動之驅動件220可使得移動件230沿著第二軸線A2上升並釋放兩調整環122a、122b（如第3圖所示）。In some embodiments, as shown in FIGS. 3 to 5, the engaging portion 223 of the driving member 220 has a first thread structure 223a. The moving member 230 has a second thread structure 231b. The first thread structure 223a and the second thread structure 231b are screwed together. The rotating driving member 220 drives the moving member 230 to move by sliding the first thread structure 223a relative to the second thread structure 231b. Thereby, when the user rotates the driving member 220 in a rotating direction (for example, clockwise), the rotating driving member 220 can cause the moving member 230 to descend along the second axis A2 and press and fix the two adjusting rings 122a, 122b. (As shown in Figure 4); when the user rotates the driving member 220 in another rotation direction (for example, counterclockwise), the rotating driving member 220 can cause the moving member 230 to rise along the second axis A2 and release both Adjust the rings 122a, 122b (as shown in Figure 3).

需說明的是，於第3圖至第5圖所示的實施方式中，驅動件220的第一螺紋結構223a為外螺紋結構，而移動件230的第二螺紋結構231b為內螺紋結構，但本創作並不以此為限。於實際應用中，驅動件220的第一螺紋結構223a可改為內螺紋結構，而移動件230的第二螺紋結構231b為外螺紋結構，同樣可達到藉由轉動驅動件220而帶動移動件230上升與下降的目的。It should be noted that, in the embodiments shown in FIGS. 3 to 5, the first thread structure 223a of the driving member 220 is an external thread structure, and the second thread structure 231b of the moving member 230 is an internal thread structure, but This creation is not limited to this. In practical applications, the first thread structure 223a of the driving element 220 can be changed to an internal thread structure, and the second thread structure 231b of the moving element 230 is an external thread structure, which can also achieve the driving of the moving element 230 by rotating the driving element 220 The purpose of rising and falling.

The elastic member 240 is disposed between the housing 210 and the moving member 230 and is configured to push the housing 210 and the moving member 230 in reverse. Thereby, the elastic force provided by the elastic member 240 can make the second coupling portion 232 of the movable member 230 tightly press against the two adjusting rings 122a and 122b. In some embodiments, the elastic member 240 is a compression spring and is sleeved on the guide pin 213, but the invention is not limited to this.

於一些實施方式中，如第2B圖至第4圖所示，兩調整環122a、122b的第一結合部122a1、122b1為遠離第一軸線A1突出之肋結構。移動件230的第二結合部232係配置以壓抵第一結合部122a1、122b1。另外，移動件230的第二結合部232具有壓抵面232a朝向兩調整環122a、122b。壓抵面232a具有凹槽232b。凹槽232b配置以壓抵與容置部分之第一結合部122a1、122b1。藉此，即可增加第二結合部232與兩調整環122a、122b之間的接觸面積，進可達到更好的固定效果。In some embodiments, as shown in FIGS. 2B to 4, the first coupling portions 122a1, 122b1 of the two adjusting rings 122a, 122b are rib structures protruding away from the first axis A1. The second coupling portion 232 of the moving element 230 is configured to press against the first coupling portions 122a1, 122b1. In addition, the second coupling portion 232 of the moving element 230 has a pressing surface 232a facing the two adjusting rings 122a and 122b. The pressing surface 232a has a groove 232b. The groove 232b is configured to press against and hold the first coupling portion 122a1, 122b1 of the receiving portion. Thereby, the contact area between the second coupling portion 232 and the two adjusting rings 122a, 122b can be increased, and a better fixing effect can be achieved.

於一些實施方式中，如第2B圖所示，基座121包含固定板塊121a、第一移動板塊121b、第二移動板塊121c、第一旋鈕121d以及第二旋鈕121e。固定模組200之殼體210係固定於固定板塊121a。第一移動板塊121b經由第一旋鈕121d可移動地銜接固定板塊121a，因此藉由轉動第一旋鈕121d即可使第一移動板塊121b沿著第一方向移動。第二移動板塊121c經由第二旋鈕121e可移動地銜接第一移動板塊121b，因此藉由轉動第二旋鈕121e即可使第二移動板塊121c沿著第二方向移動。鏡頭模組122係銜接至第二移動板塊121c。換言之，投影鏡頭組件120的基座121可帶動鏡頭模組122進行二維移動。於一些實施方式中，前述第一方向垂直於第一軸線A1與第二軸線A2，而前述第二方向平行於第二軸線A2，但本創作並不以此為限。In some embodiments, as shown in FIG. 2B, the base 121 includes a fixed plate 121a, a first moving plate 121b, a second moving plate 121c, a first knob 121d, and a second knob 121e. The housing 210 of the fixed module 200 is fixed to the fixed plate 121a. The first moving plate 121b is movably connected to the fixed plate 121a via the first knob 121d, so by rotating the first knob 121d, the first moving plate 121b can be moved along the first direction. The second moving plate 121c is movably connected to the first moving plate 121b via the second knob 121e, so by rotating the second knob 121e, the second moving plate 121c can be moved along the second direction. The lens module 122 is connected to the second moving plate 121c. In other words, the base 121 of the projection lens assembly 120 can drive the lens module 122 to move in two dimensions. In some embodiments, the aforementioned first direction is perpendicular to the first axis A1 and the second axis A2, and the aforementioned second direction is parallel to the second axis A2, but this creation is not limited to this.

於一些實施方式中，如第2A圖與第2B圖所示，第一旋鈕121d與第二旋鈕121e可設計成具有類似於撥片的外型，以適於使用者轉動。In some embodiments, as shown in Figs. 2A and 2B, the first knob 121d and the second knob 121e may be designed to have an appearance similar to a paddle, so as to be suitable for the user to rotate.

於一些實施方式中，在平行於前述第一方向與第二方向的參考平面上（如第5圖所示之剖面），第二結合部232的凹槽232b的輪廓線具有較小的曲率（亦即，具有較大的曲率半徑），而兩調整環122a、122b的第一結合部122a1、122b1的外緣具有較大的曲率（亦即，具有較小的曲率半徑）。藉此，即使鏡頭模組122進行二維移動，第二結合部232仍可適當地接觸並壓抵第一結合部122a1、122b1，從而可避免固定模組200的固定功能失效。In some embodiments, on a reference plane parallel to the aforementioned first direction and second direction (such as the cross-section shown in Figure 5), the contour line of the groove 232b of the second coupling portion 232 has a smaller curvature ( That is, it has a larger radius of curvature), and the outer edges of the first coupling portions 122a1, 122b1 of the two adjusting rings 122a, 122b have a larger curvature (ie, have a smaller radius of curvature). In this way, even if the lens module 122 moves in two dimensions, the second coupling portion 232 can still properly contact and press against the first coupling portions 122a1, 122b1, thereby avoiding failure of the fixing function of the fixing module 200.

需說明的是，兩調整環122a、122b的第一結合部122a1、122b1與移動件230的第二結合部232之間的結合形式並不限於前述之壓抵形式，於實際應用中亦可為卡扣…等結合形式。It should be noted that the coupling form between the first coupling portion 122a1, 122b1 of the two adjusting rings 122a, 122b and the second coupling portion 232 of the moving part 230 is not limited to the aforementioned pressing form, and can also be in practical applications. Snap... and other combined forms.

由以上對於本創作之具體實施方式之詳述，可以明顯地看出，於本創作的投影鏡頭組件與投影機中，在調整環被調整至定位之後，藉由使固定模組的驅動件相對於殼體轉動，即可驅使移動件壓抵固定調整環，進而可有效地解決因突來的外力而使調好的畫面跑掉、失真的問題。另外，由於移動件的第二結合部是由彈性材料所製成，因此以第二結合部壓抵調整環可彌補調整環的組裝公差，進而可達到更好的固定效果。再者，於投影鏡頭組件的鏡頭模組設置在基座的移動板塊上而可二維移動的實施方式中，固定模組的固定功能並不因鏡頭模組的移動而失效。From the above detailed description of the specific implementation of this creation, it can be clearly seen that in the projection lens assembly and the projector of this creation, after the adjustment ring is adjusted to the position, the driving part of the fixed module is opposed to The rotation of the housing can drive the moving part to press against the fixed adjustment ring, which can effectively solve the problem of running off and distorting the adjusted picture due to a sudden external force. In addition, since the second coupling portion of the moving part is made of elastic material, pressing the second coupling portion against the adjustment ring can compensate for the assembly tolerance of the adjustment ring, thereby achieving a better fixing effect. Furthermore, in the embodiment where the lens module of the projection lens assembly is arranged on the movable plate of the base and can be moved in two dimensions, the fixing function of the fixed module is not invalidated by the movement of the lens module.
