In this way, when the lens module uses ultra-thin filters, such as phosphate filters, the filters can be glued Adhesive to the lens holder, there will be a high temperature and high humidity environment during the assembly process or use of the lens module. Since the thermal expansion coefficient of the filter is lower than that of glue, it is easy to cause the above high temperature and high humidity environment. The filter is cracked.

Among them, the shape of the filter 20 is substantially the same as the shape of the mounting groove 12, and the corner 21 of the filter 20 is opposite to the corner of the mounting groove 12 during assembly. Since cracks and stress concentration are more likely to occur at the corners, the glue avoiding groove 13 is arranged at the corners of the installation groove 13 to improve the effect of cracks.
避胶槽13可以直接由边角的一部分向下凹陷形成,也可以在靠近各个边角一定间距的位置凹陷形成避胶槽13,上述实施例均落入避胶槽13位于安装槽12的边角处这一范畴。The glue avoidance groove 13 can be directly formed by a part of the corners recessed downward, or it can be recessed to form the glue avoidance groove 13 at a certain distance near each corner. The above embodiments all fall into the glue avoidance groove 13 located on the side of the installation groove 12 The category at the corner.
在图1所示的具体实施例中,所述避胶槽13由所述安装槽12的槽底壁的边角下沉 形成。由此,不仅方便加工,而且使滤光片20安装后边角能够完全悬空,减少了边角受力。In the specific embodiment shown in FIG. 1, the glue avoidance groove 13 is formed by sinking the corners of the groove bottom wall of the installation groove 12. This not only facilitates the processing, but also enables the corners of the filter 20 to be completely suspended after installation, reducing the stress on the corners.
在一些实施例中,安装面121外轮廓为矩形,由此能够为滤光片20的安装提供周向定位,提高了装配效率。In some embodiments, the outer contour of the mounting surface 121 is rectangular, which can provide circumferential positioning for the installation of the filter 20 and improve the assembly efficiency.
在一些实施例中,所述安装槽12为正方形,且四个边角均设有避胶槽13。图1-2为本公开一个实施例的镜座10,图3-4为该实施例的镜座10与滤光片20的组装结构。在上述实施例中,避胶槽13位于安装槽12的一个边角处。In some embodiments, the mounting groove 12 is square, and four corners are provided with glue avoiding grooves 13. FIGS. 1-2 show the lens holder 10 according to an embodiment of the disclosure, and FIGS. 3-4 show the assembly structure of the lens holder 10 and the filter 20 of this embodiment. In the above embodiment, the glue avoiding groove 13 is located at one corner of the installation groove 12.
图5-6为本公开一个实施例的镜座10,图7-8为该实施例的镜座10与滤光片20的组装结构。在上述实施例中,安装槽12的四个边角均设有避胶槽13。如图5-6所示,安装槽12的四个边角均下沉形成了避胶槽13,四个避胶槽13可以呈中心对称分布。由此,四角下沉比1个角下沉减少29%裂纹数量,进一步降低了产生裂纹的风险。FIGS. 5-6 show the lens holder 10 according to an embodiment of the disclosure, and FIGS. 7-8 show the assembly structure of the lens holder 10 and the filter 20 according to this embodiment. In the above embodiment, the four corners of the installation groove 12 are provided with glue avoidance grooves 13. As shown in Figs. 5-6, the four corners of the installation groove 12 are sunk to form a glue avoiding groove 13, and the four glue avoiding grooves 13 can be distributed symmetrically in the center. As a result, the four-corner sinking reduces the number of cracks by 29% compared to the one-corner sinking, further reducing the risk of cracks.
在一些实施例中,避胶槽13位于角落区域,定义所述角落区域为:与所述镜片安装孔11同心且与所述槽底壁的至少一个外边沿相切的圆环的外侧的区域。这样,避胶槽13设置在上述角落区域能够使滤光片20与安装面121的接触面积在周向上分布的更均匀,改善应力集中的效果更好。In some embodiments, the glue avoiding groove 13 is located in a corner area, and the corner area is defined as: the area outside the ring that is concentric with the lens mounting hole 11 and tangent to at least one outer edge of the groove bottom wall . In this way, the glue avoiding groove 13 is arranged in the above-mentioned corner area, so that the contact area between the filter 20 and the mounting surface 121 can be more evenly distributed in the circumferential direction, and the effect of improving stress concentration is better.
具体地,安装槽12为正方形,圆环内切于安装槽12的外边沿且两者之间限定出四个角落区域,四个角落区域中的至少一个设有避胶槽13。也就是说,四个角落区域中可以仅仅一个设有避胶槽13,也可以四个角落区域均凹陷并形成有避胶槽13。Specifically, the mounting groove 12 is a square, a circular ring is inscribed on the outer edge of the mounting groove 12 and four corner areas are defined between the two, and at least one of the four corner areas is provided with a glue avoiding groove 13. In other words, only one of the four corner areas may be provided with the glue avoiding groove 13 or the four corner areas may be recessed and formed with the glue avoiding groove 13.
进一步地,避胶槽13与圆环间隔开设置,避胶槽13与圆环在径向的隔开距离是避胶槽13在径向上的最大尺寸的0.5-1.5倍。这样,既能够保证足够的胶接面,还能够使滤光片20的边角21悬空,在避免裂纹的同时兼顾了滤光片20与镜座10连接的稳定性和可靠性。Further, the glue avoiding groove 13 is spaced apart from the ring, and the distance between the glue avoiding groove 13 and the ring in the radial direction is 0.5-1.5 times the maximum size of the glue avoiding groove 13 in the radial direction. In this way, a sufficient bonding surface can be ensured, and the corners 21 of the filter 20 can be suspended, so that the stability and reliability of the connection between the filter 20 and the lens holder 10 are taken into account while avoiding cracks.
在一些实施例中,避胶槽13的下沉深度为0.05mm-2mm。由此,采用上述深度的避胶槽13避免了对镜座10的强度造成削弱。In some embodiments, the sinking depth of the glue avoiding groove 13 is 0.05 mm-2 mm. Therefore, the use of the glue avoiding groove 13 with the above-mentioned depth avoids weakening the strength of the lens holder 10.
在一些实施例中,避胶槽13在安装面121的开口形状为三角形、方形、半圆形、椭圆形、圆形中的任一种。由此,采用上述形状的避胶槽13更方便加工生产。In some embodiments, the opening shape of the glue avoiding groove 13 on the mounting surface 121 is any one of a triangle, a square, a semicircle, an ellipse, and a circle. Therefore, the glue avoiding groove 13 with the above-mentioned shape is more convenient for processing and production.
具体地,避胶槽13可以是等截面或者自底至顶逐渐扩张的沉孔。沉孔的外形尺寸从0.5mm-3mm之间可依据实际允许空间设计。Specifically, the glue avoiding groove 13 may be a counterbore with a constant cross section or gradually expanding from bottom to top. The size of the counterbore can be designed according to the actual allowable space from 0.5mm-3mm.
在一些实施例中,避胶槽13在安装面121的开口形状为等腰直角三角形,且避胶槽13的侧壁连接处通过圆角过渡。由此,采用上述形状的避胶槽13且采用圆角设计,避免了胶水在避胶槽13与表面的交界处局部堆积太多。In some embodiments, the opening shape of the glue avoiding groove 13 on the mounting surface 121 is an isosceles right triangle, and the sidewalls of the glue avoiding groove 13 transition through rounded corners. Therefore, the use of the glue avoidance groove 13 of the above-mentioned shape and the rounded corner design avoids the local accumulation of too much glue at the junction between the glue avoidance groove 13 and the surface.
根据本公开第二方面实施例的滤光片组件包括:上述实施例的镜座10以及滤光片20,滤光片20与安装槽12的槽底壁的表面通过胶粘接,且滤光片20的至少一个边角悬空于避胶槽13的上方。由此,滤光片20伸入到镜座10内且通过胶粘在安装槽的安装面121,滤光片20的至少一个边角悬空于避胶槽13上方,能够避空胶水,以减少滤光片20边角处的应力或应变集中,降低了滤光片20产生裂纹的风险,提高了产品良率。The filter assembly according to the embodiment of the second aspect of the present disclosure includes: the lens holder 10 and the filter 20 of the above embodiment, the filter 20 and the surface of the bottom wall of the mounting groove 12 are bonded by glue, and the filter At least one corner of the sheet 20 is suspended above the glue avoiding groove 13. As a result, the filter 20 extends into the lens holder 10 and is glued to the mounting surface 121 of the mounting groove. At least one corner of the filter 20 is suspended above the glue avoiding groove 13, so that the glue can be avoided and the glue is reduced. The stress or strain concentration at the corners of the filter 20 reduces the risk of cracks in the filter 20 and improves the product yield.
在一些实施例中,滤光片20为磷酸盐材质的蓝玻璃。滤光片能够过滤人眼不可见的红外光和紫外光。由于磷酸盐材质的蓝玻璃的膨胀系数跟胶水的差别较大,因此避胶槽13的设计尤其适用于磷酸盐材质的蓝玻璃,能有效缓解蓝玻璃产生裂纹。In some embodiments, the filter 20 is blue glass made of phosphate. The filter can filter infrared and ultraviolet light invisible to the human eye. Since the expansion coefficient of blue glass made of phosphate is quite different from that of glue, the design of the glue avoidance tank 13 is especially suitable for blue glass made of phosphate, which can effectively alleviate cracks in blue glass.
在一些实施例中,所述滤光片20的厚度为0.2mm-0.3mm。由此,采用上述较薄的滤光片20使摄像模组更小型化,而且上述避胶槽13的设计尤其适用于上述厚度的滤光片20的防裂。In some embodiments, the thickness of the filter 20 is 0.2 mm-0.3 mm. Therefore, the thinner filter 20 is used to make the camera module more compact, and the design of the glue avoiding groove 13 is particularly suitable for crack prevention of the filter 20 with the above thickness.
根据本公开第三方面实施例的摄像模组,包括所述的滤光片组件。由此,摄像模组能够平衡拍照画面的色彩,还原真实色彩。The camera module according to an embodiment of the third aspect of the present disclosure includes the aforementioned filter assembly. In this way, the camera module can balance the color of the picture taken and restore the true color.
根据本公开第四方面实施例的移动终端,包括上述实施例的摄像模组。采用上述摄像模组的移动终端,摄像模组的滤光片20更不容易产生裂纹,质量更可靠、更轻薄。The mobile terminal according to the embodiment of the fourth aspect of the present disclosure includes the camera module of the above-mentioned embodiment. In the mobile terminal using the above-mentioned camera module, the filter 20 of the camera module is less prone to cracks, the quality is more reliable, and the lighter and thinner.
