Description
本發明涉及光學系統領域，尤其涉及一種鏡筒與鏡座之間扭力易於控制之鏡頭模組。 The invention relates to the field of optical systems, and in particular to a lens module with easy to control torque between a lens barrel and a lens holder.
隨著多媒體技術飛速發展，數位相機、攝像機及帶有攝像頭之手機愈來愈受廣大消費者青睞，於人們對數位相機、攝像機及手機攝像頭拍攝物體之影像品質提出更高要求之同時，對數位相機、攝像機及帶有攝像頭之手機等產品需求量亦日益增加。數位相機、攝像機及手機攝像頭等攝影裝置中，鏡頭模組為一個不可缺少之部件。 With the rapid development of multimedia technology, digital cameras, camcorders and mobile phones with cameras are increasingly favored by consumers. At the same time, people put more demands on the image quality of digital cameras, camcorders and mobile phone cameras. Demand for products such as cameras, camcorders and mobile phones with cameras is also increasing. In a camera such as a digital camera, a video camera, and a mobile phone camera, the lens module is an indispensable component.
鏡頭模組通常包括鏡筒、鏡座、光學成像元件與影像感測器。所述光學成像元件收容於鏡筒，所述影像感測器設置於鏡座。所述鏡筒具有外螺紋，所述鏡座具有內螺紋。所述光學成像元件與影像感測器藉由鏡筒與鏡座之間之配合光學耦合。 The lens module usually includes a lens barrel, a lens holder, an optical imaging element, and an image sensor. The optical imaging element is housed in a lens barrel, and the image sensor is disposed on the lens holder. The lens barrel has an external thread, and the lens holder has an internal thread. The optical imaging element and the image sensor are optically coupled by a fit between the lens barrel and the lens holder.
通常來說，鏡頭模組之鏡筒與鏡座間扭力太小即鏡筒之外螺紋與鏡座之內螺紋配合過鬆，容易導致鏡筒與鏡座相互脫離；當鏡筒與鏡座間扭力太大即鏡筒之外螺紋與鏡座之內螺紋配合過緊，會導致鏡筒之外螺紋與鏡座之內螺紋互相磨損，鏡筒與鏡座之間之扭力值於一定範圍內之鏡頭模組才合格。 Generally speaking, the torque between the lens barrel and the lens holder of the lens module is too small, that is, the external thread of the lens barrel and the internal thread of the lens holder are loosely fitted, which easily causes the lens barrel and the lens holder to be separated from each other; when the lens barrel and the lens holder are too twisted If the thread outside the lens barrel is too tightly fitted with the internal thread of the lens holder, the external thread of the lens barrel and the internal thread of the lens holder will wear each other, and the torque between the lens barrel and the lens holder will be within a certain range. The group is qualified.
惟，要分別於體積小之鏡筒與鏡座上形成形狀完全匹配之外螺紋與內螺紋，加工成本較高。且，於該鏡頭模組組裝完成後還需進行扭力測試以淘汰掉鏡筒與鏡座之間扭力值不符合規定之鏡頭模組，會耗費大量人力物力。此外，鏡筒之外螺紋與鏡座之內螺紋會在鏡頭模組之反復組裝或分解過程中因相互作用發生磨損，該磨損將直接導致鏡筒與鏡座之間結合不緊密，進而影響光學成像元件與影像感測器之間之光學耦合，影響鏡頭模組之成像品質。 However, it is necessary to form a shape that perfectly matches the external thread and the internal thread on the small-sized lens barrel and the lens holder, and the processing cost is high. Moreover, after the lens module is assembled, a torque test is required to eliminate the lens module whose torque value does not conform to the specification between the lens barrel and the lens holder, which consumes a lot of manpower and material resources. In addition, the external thread of the lens barrel and the internal thread of the lens holder may wear due to the interaction during the repeated assembly or disassembly of the lens module, and the wear will directly lead to the inconsistency between the lens barrel and the lens holder, thereby affecting the optical The optical coupling between the imaging element and the image sensor affects the imaging quality of the lens module.
有鑑於此，提供一種鏡筒鏡座之間扭力易於控制之鏡頭模組實屬必要。 In view of this, it is necessary to provide a lens module in which the torque between the lens barrel holders is easily controlled.
一種鏡頭模組包括鏡座、鏡筒及彈性元件。所述鏡座具有第一螺紋。所述鏡筒收容於所述鏡座。所述鏡筒具有用於與鏡座之第一螺紋鬆配合之第二螺紋。所述彈性元件設置於所述鏡座與所述鏡筒之間，用於提供平行於鏡頭模組之中心軸線方向之彈力以使得第一螺紋與第二螺紋相接觸從而固定所述鏡座與鏡筒。 A lens module includes a lens holder, a lens barrel and an elastic member. The mirror mount has a first thread. The lens barrel is received in the lens holder. The lens barrel has a second thread for loosely engaging a first thread of the lens holder. The elastic element is disposed between the lens holder and the lens barrel for providing an elastic force parallel to a central axis direction of the lens module such that the first thread contacts the second thread to fix the lens holder and The lens barrel.
本技術方案之鏡座之第一螺紋與鏡筒之第二螺紋之間為鬆配合，並藉由所述彈性元件向所述鏡筒提供平行於鏡頭模組之中心軸線方向之彈力以將所述鏡筒固定於所述鏡座。不僅可減少所述第一螺紋與第二螺紋之加工難度，避免所述第一螺紋與第二螺紋之磨損影響鏡頭模組成像品質。而且可方便地藉由控制所述彈性元件之彈性係數而控制所述鏡座與鏡筒間之扭力大小。 The first thread of the lens holder of the technical solution is loosely engaged with the second thread of the lens barrel, and the elastic element supplies the elastic force of the lens barrel parallel to the central axis of the lens module to The lens barrel is fixed to the lens holder. The processing difficulty of the first thread and the second thread can be reduced, and the wear of the first thread and the second thread can be prevented from affecting the image quality of the lens module. Moreover, the amount of torque between the lens holder and the lens barrel can be conveniently controlled by controlling the elastic modulus of the elastic member.

In this embodiment, the elastic member 13 is a spring piece, which is substantially annular, and includes a circular body 130 and at least two elastic arms 131 connected to the body 130. The number of the elastic arms 131 is three and is equiangularly distributed around the central axis of the elastic member 13. Each of the elastic arms 131 has a connecting end 132 and an extending end 133. The connecting end 132 is connected to the body 130. The extending end 133 extends from the body 130 along the axis of the lens holder 11 away from the body 130, so that when elastic When the component 13 is in a natural state, each of the elastic arms 131 is at an angle to the plane of the body 130. The body 130 of the elastic member 13 is in contact with the bearing surface 1120 of the carrier 112, and the extended end 133 of the elastic arm 131 abuts against the third end surface 1200 of the lens barrel 12. Due to the compression of the lens barrel 12, the elastic arm 131 is deformed, and the angle between it and the plane of the body 130 is reduced. Due to the elastic force of the elastic member 13, the third inclined surface 1205 of each of the screws 1204 of the lens barrel 12 is in complete contact with a first inclined surface 1112 of the corresponding screw groove 1111, and each fourth inclined surface 1206 Both are parallel to a corresponding second slope 1113, as shown in FIG. Thereby, the lens holder 11 and the lens barrel 12 are tightly coupled together. It can be understood that when the first thread 1110 and the second thread 1203 are shaped When the mirror base 11 and the lens barrel 12 are tightly coupled, the shape of the elastic member 13 is changed to a certain extent. When it is necessary to change the torque of the cooperation between the lens holder 11 and the lens barrel 12, only It can be replaced by an elastic member 13 having a corresponding elastic modulus. Thereby, the torque of the cooperation between the lens holder 11 and the lens barrel 12 can be conveniently controlled. Of course, the elastic element 13 can also be a spring, an elastic pad or other alternative.
請一併參閱圖6與圖7，本技術方案第二實施例提供之鏡頭模組20與第一實施例提供之鏡頭模組10大致相同，其區別在於，所述承載台212包括複數承載塊2123，所述彈性元件23包括與所述複數承載塊2123一一對應之複數彈簧230。每一彈簧230均包括相對之第一端部231與第二端部232，所述第一端部231固定於一個承載塊2123，所述第二端部232抵靠於所述鏡筒22之第三端面2200。所述螺牙2204之截面為三角形。 Referring to FIG. 6 and FIG. 7 , the lens module 20 provided in the second embodiment of the present invention is substantially the same as the lens module 10 provided in the first embodiment, except that the carrier 212 includes a plurality of carrier blocks. 2123, the elastic element 23 includes a plurality of springs 230 corresponding to the plurality of carrier blocks 2123. Each spring 230 includes an opposite first end 231 and a second end 232. The first end 231 is fixed to a carrier block 2123, and the second end 232 abuts against the lens barrel 22. The third end face 2200. The thread 2204 has a triangular cross section.
每一承載塊2123均自第一底壁2101之內側面2106向靠近所述鏡座21之中心軸線方向垂直延伸。本實施例中，所述複數承載塊2123之數量為兩個，且環繞所述鏡頭模組20之中心軸線等角度分佈。與所述複數承載塊2123對應地，所述複數彈簧230之數量亦為兩個。 Each of the carrier blocks 2123 extends perpendicularly from the inner side surface 2106 of the first bottom wall 2101 toward the central axis of the mirror mount 21. In this embodiment, the number of the plurality of carrier blocks 2123 is two, and is distributed equiangularly around the central axis of the lens module 20. Corresponding to the plurality of carrier blocks 2123, the number of the plurality of springs 230 is also two.
可理解，所述彈簧230之數量為一個亦可，僅需彈簧230與鏡頭模組20同軸設置，如此則可使得光線可從彈簧230之中間藉由從而進入影像感測器。此時，承載台212可為環形，亦可包括複數承載塊。 It can be understood that the number of the springs 230 is one, and only the spring 230 is disposed coaxially with the lens module 20, so that light can be passed from the middle of the spring 230 to enter the image sensor. At this time, the carrying platform 212 may be a ring shape, and may also include a plurality of carrier blocks.
所述螺牙2204僅包括相連接之第三斜面2205與第四斜面2206。所述第三斜面2205靠近所述鏡頭模組20之物側，其與所述鏡頭模組20之中心軸線之間之第三夾角大小亦為θ 1。所述第四斜面2206 靠近所述鏡頭模組之像側，其與所述鏡頭模組10之中心軸線之間之第四夾角小於θ 2。於彈力作用下，所述第三斜面2205與所述第一斜面2112之間完全接觸，所述第四斜面2206與第二斜面2113相對但不平行。 The thread 2204 includes only the third bevel 2205 and the fourth bevel 2206 that are connected. The third inclined surface 2205 is adjacent to the object side of the lens module 20, and the third angle between the third oblique surface 2205 and the central axis of the lens module 20 is also θ 1 . The fourth slope 2206 A fourth angle between the image side of the lens module and the central axis of the lens module 10 is less than θ 2 . Under the elastic force, the third inclined surface 2205 is in complete contact with the first inclined surface 2112, and the fourth inclined surface 2206 is opposite to the second inclined surface 2113 but not parallel.
當然，所述第三斜面與所述第一斜面之間不一定要求完全接觸，所述螺槽、螺牙之形狀亦不限於為三角形或梯形，還可為其他形狀，僅需複數螺槽均與複數螺牙一一對應、螺距相等，且每一螺槽之容積均大於與之對應之螺牙之體積即可。 Of course, the third inclined surface and the first inclined surface do not necessarily require complete contact. The shape of the screw groove and the screw is not limited to a triangle or a trapezoid, and may be other shapes, and only a plurality of slots are required. Corresponding to the plurality of thread teeth, the pitch is equal, and the volume of each of the slots is greater than the volume of the corresponding thread.
本技術方案之鏡座之第一螺紋與鏡筒之第二螺紋之間為鬆配合，並藉由所述彈性元件向所述鏡筒提供平行於鏡頭模組之中心軸線方向之彈力以將所述鏡筒固定於所述鏡座。不僅可減少所述第一螺紋與第二螺紋之加工難度，避免所述第一螺紋與第二螺紋之磨損影響鏡頭模組成像品質。而且可方便地藉由控制所述彈性元件之彈性係數而控制所述鏡座與鏡筒間之扭力大小。 The first thread of the lens holder of the technical solution is loosely engaged with the second thread of the lens barrel, and the elastic element supplies the elastic force of the lens barrel parallel to the central axis of the lens module to The lens barrel is fixed to the lens holder. The processing difficulty of the first thread and the second thread can be reduced, and the wear of the first thread and the second thread can be prevented from affecting the image quality of the lens module. Moreover, the amount of torque between the lens holder and the lens barrel can be conveniently controlled by controlling the elastic modulus of the elastic member.
