技术领域Technical field
本发明涉及虚拟现实技术领域，具体涉及一种针对虚拟现实中的光学镜片调焦组件。The present invention relates to the field of virtual reality technologies, and in particular, to an optical lens focusing component for virtual reality.
背景技术Background technique
虚拟现实(Virtual Reality：VRa)技术，简称虚拟技术，是一种利用电脑技术模拟产生一个虚拟空间，并在虚拟空间中提供沉浸体验的技术，该技术集成了电脑图形、电脑仿真、人工智能、显示及网络并行处理等技术，是一种高级模拟技术。VR设备是应用VR技术的人机交互设备，常见的VR设备，例如虚拟现实设备，能将人体对外界的视觉、听觉等感知隔离，引导用户产生身临其境的VR体验。Virtual Reality (VRa) technology, referred to as virtual technology, is a technology that uses computer technology to simulate a virtual space and provide an immersive experience in a virtual space. The technology integrates computer graphics, computer simulation, artificial intelligence, Technologies such as display and network parallel processing are advanced analog technologies. VR devices are human-computer interaction devices that use VR technology. Common VR devices, such as virtual reality devices, can isolate the human body from the perception of the outside world, and guide users to create an immersive VR experience.
VR眼镜是一种常见的头戴设备，例如，采用专利号为US20170017078B公开的光学组件所制作的头戴设备。在VR眼镜中，镜头是重要的光学部件，镜头的一侧是显示屏，显示屏发出的图像经过镜头的光学处理，在位于镜头另一侧的人眼中成像。VR glasses are a common head-mounted device, for example, a head-mounted device made with an optical component disclosed in US Pat. No. US20170017078B. In VR glasses, the lens is an important optical component. One side of the lens is the display screen. The image from the display screen is optically processed by the lens and imaged in the human eye on the other side of the lens.
虚拟现实设备中使用的光学组件，一般包括镜筒以及安装在镜筒内的光学镜片。在实际使用中，通常需要针对短距离的光学镜片的焦距调焦。目前已有的一种光学镜片调焦组件中，采用在镜筒的轴向上，对内镜筒或外镜筒进行拉伸或收缩，以实现调节焦距。然而，在拉动内镜筒或外镜筒时，由于施力方向是朝向面部的外侧，因此，需要一只手按住镜框，另一只手对内镜筒或外镜筒进行拉伸，否则会导致VR眼镜从面部脱落，这导致整个调焦过程较为不便。An optical component used in a virtual reality device generally includes a lens barrel and an optical lens mounted in the lens barrel. In actual use, focus adjustment for short distance optical lenses is generally required. In an optical lens focusing assembly currently available, the inner lens barrel or the outer barrel is stretched or contracted in the axial direction of the lens barrel to achieve a focal length adjustment. However, when pulling the inner tube or the outer tube, since the direction of the force is toward the outer side of the face, it is necessary to hold the frame with one hand and stretch the inner or outer tube with the other hand, otherwise This can cause the VR glasses to fall off the face, which makes the entire focusing process more inconvenient.

The left barrel mechanism 21 and the right barrel mechanism 23 have the same structure. , collectively referred to as optical lens focusing components. Specifically, the left lens barrel mechanism 21 and the left display screen 22 are mounted on the left screen bracket and the left display screen 22 is located behind the left barrel mechanism 21, and the left display screen is entirely located inside the left screen bracket; the right barrel mechanism 23 and The right display screen 24 is mounted on the right screen bracket 13 and the right display screen 24 is located behind the right barrel mechanism 23, and the right display screen 24 is entirely located inside the right screen bracket 13. The side edges of the left display screen 22 and the right display screen 24 have a chamfer angle. As shown in FIG. 1, the right lower corner side of the left display screen 22 has a chamfered angle. The lower left side of the right display 24 has a chamfered corner. The left screen bracket and the right screen bracket 13 are two independent screen brackets, each of which is a hollow ring structure. Since the two screen holders are hollow, it is realized that the contents displayed by the corresponding display screen are viewed through the lenses of the left barrel mechanism 21 and the right barrel mechanism 23. The hollow ring of the screen bracket may be a circular or polygonal shape or an irregular shape, which is determined according to the shape of the optical module and the shape of the virtual reality device housing. The surface of each screen bracket that is in contact with the display screen is a screen contact surface, and the screen contact surface is used to fit the surface of the display screen. Specifically, it can be set as a smooth surface, and the screen contact surface is set as a smooth surface to avoid damage to the display screen. At the same time, the display and the screen bracket are well fitted. In this embodiment, the screen contact surface is not specifically defined as a smooth surface or a rough surface. In this embodiment, in order to better achieve the fit of the screen contact surface and the display screen surface, a soft double-sided adhesive glue may be disposed between the two, and the double-sided adhesive glue may be an annular ring corresponding to the shape of the screen support. The screen holder is pasted with the display through a double-sided adhesive. Corresponding to the screen contact surface is an optical module contact surface, and the optical module contact surface is respectively attached to the left barrel mechanism 21 and the right barrel mechanism 23. When the screen brackets are assembled with the display screen and the optical module respectively, the screen brackets serve to facilitate the installation, and at the same time, the three form a confined space, which plays a dustproof role.

Further, the inclined grooves 213 are not limited to being uniformly distributed in the circumferential direction of the outer barrel 211, but it is necessary to satisfy that the plurality of inclined grooves 213 are located on the same horizontal plane. The sectional shape of the outer barrel 211 is not limited to the circular shape shown in Fig. 1, and may be elliptical or rhombic or irregular. In order to better adapt to the morphological characteristics of the human body, near the nose bridge of the human body, it can be set to match the shape of the human nose bridge, that is, a simple circular cut portion is formed to have an inclined surface matching the nose bridge. Therefore, in order to accommodate a specific virtual reality device housing, and to reduce the volume of the overall virtual reality device, the cross-sectional shape of the outer barrel 211 may depend on the specific virtual reality housing.
(2)外光学镜片212：外光学镜片212固定在外镜筒211上，具体的，如图2所示，外光学镜片212固定在外镜筒211的内侧顶部，内侧顶部即为远离内镜筒214的一侧。外光学镜片212与外镜筒211的固定方式具体可以是：通过塑胶将外光学镜片212固定在外镜筒211的内侧顶部，通过塑胶固定可以保证外光学镜片212稳定的固定在外镜筒211上，并且能有效防尘。需要说明的是，本发明不具体限定两者的固定方式。为了便于说明，将外镜筒211和外光学镜片212的组合结构定义为第一组件。(2) The outer optical lens 212: the outer optical lens 212 is fixed on the outer lens barrel 211.

The inside of the inclined groove 213 is slidable along the inclined groove 213, thereby driving the movement of the inner barrel 214. Since the present invention does not limit the number of the inclined grooves 213, the number of the positioning features is not specifically limited. When the number of the inclined grooves 213 is three and uniformly distributed along the circumferential direction of the outer barrel 211, the three positioning features are simultaneously moved in the inclined groove 213, thereby ensuring that the inner optical lens 217 on the inner barrel 214 is moving up and down. Make them all on one plane. Further, since the outer barrel 211 is in contact with the inner barrel 214, in order to improve the sliding of the inner barrel 214 during the focusing process, an oil layer for lubricating is added between the inner barrel 214 and the outer barrel 211, and the inner layer is increased. The sliding of the lens barrel 214 is flexible, and the oil layer can prevent the dust from entering the inside to a certain extent, thereby preventing dust. A specific oil layer may be formed by applying damping oil between the inner barrel 214 and the outer barrel 211, and it should be understood that other ways of improving the sliding flexibility between the inner barrel 214 and the outer barrel 211 are the same for the present application. protected range. When the positioning feature is three, the structure of the three positioning features can be divided into two fixing screws 220 and a toggle fixing screw 221, and the two fixing screws 220 and the toggle fixing screws 221 are fixed by the fixing screw holes. On the lens barrel 214, the two fixing screws 220 and the toggle fixing screws 221 respectively protrude into the inclined groove 213 and are slidable along the inclined groove 213. In order to improve the comfort of the push-and-fixing screw 221, the user can facilitate the dialing during the use process.

Specifically, the light blocking member 78 may be selected from a soft material having a certain hardness, being breathable, and capable of preventing light from transmitting. Preferably, in order to facilitate the appearance of the light shielding component during use, a material having a certain elasticity and not easy to wrinkle may be selected, such as a pull cotton, a Lycra or the like. For example, the material is selected from a synthetic fabric having two layers, one for shading and the other for air permeability and deformation. Since the general fabric is relatively soft and difficult to mold, in order to solve the problem, the elasticity, hardness and abrasion resistance of the synthetic fabric are improved, and the two layers of the fabric are synthesized by glue. The light blocking member 78 has a hollow area for accommodating the front end of the virtual reality device body. Specifically, the hollow area includes a face contact surface and a virtual device connection surface; the face contact surface is for contacting the user's face, and the virtual device connection surface is used for the virtual reality device The viewing side of the inside of the frame is connected; or the hollow area includes a face contact surface and a virtual device connection surface; the face contact surface is for contacting the user's face, and the virtual device connection surface is for connecting with the outside of the frame of the virtual reality device.

The side wall and the other end are slidable in the inclined groove 213 through the inclined groove 213. The positioning feature (specifically, the fixing screw 220 and the toggle fixing screw 221) is a virtual reality device protruding control key, and when the positioning feature (specifically, the fixing screw 220 and the toggle fixing screw 221) is adjusted, the inner lens barrel is adjusted. When the outer lens barrel 211 is relatively slid along the outer lens barrel 211, the distance between the outer optical lens 212 fixed to the outer lens barrel 211 and the inner optical lens 217 fixed to the inner lens barrel 214 is adjustable, and focusing of the optical component is achieved. In order to facilitate the operation of the protruding control button, the bottom surface of the light shielding member 78 is provided with an opening for the virtual reality device to protrude the control key, that is, the positioning feature is exposed, and the shading is realized while achieving focusing. The size of the shading assembly 7 of the virtual reality device may be such that the front end lateral distance of the shading assembly 7 is relatively smaller than the rear end longitudinal distance in order to adapt to the size of the human head shape. Generally, the front end of the shading module has a lateral length of any value in the range of 50 to 250 mm, preferably any value in the range of 120 to 170 mm, and particularly 150 to 160 mm, which is most suitable for the mass of the user, such as 155 mm.

Spirit and scope.
作为一种可选的实施方式，本申请实施例还提供一种光学镜片调焦组件，包括：外镜筒211、固定在外镜筒211的外光学镜片212、内镜筒214、固定在内镜筒214的内光学镜片217和定位特征件；外镜筒211侧壁上设有至少一个倾斜槽213；内镜筒214内置于外镜筒211；定位特征件与倾斜槽213一一对应，各定位特征件一端固定在内镜筒214的侧壁，另一端穿过倾斜槽213可在倾斜槽213内滑动。As an optional implementation manner, the embodiment of the present application further provides an optical lens focusing assembly, including: an outer lens barrel 211, an outer optical lens 212 fixed to the outer lens barrel 211, an inner lens barrel 214, and a fixed endoscope. The inner optical lens 217 and the positioning feature of the barrel 214; at least one inclined groove 213 is disposed on the side wall of the outer barrel 211; the inner barrel 214 is built in the outer barrel 211; the positioning features are in one-to-one correspondence with the inclined grooves 213, respectively One end of the positioning feature is fixed to the side wall of the inner lens barrel 214, and the other end is slidable in the inclined groove 213 through the inclined groove 213.
请参阅图23，其中，倾斜槽213的内周面包括两个周向面2131以及连接于两个周向面2131之间的两个径向面2132。两个周向面2131沿着倾斜槽213的周向延伸，两个周向面2131为相互平行的两个平面，可保证定位特征件可在倾斜槽213内平滑移动，避免通过拨动定位特征件调节外光学镜片212与内光学镜片217之间的距离时，定位特征件在倾斜槽213内发生卡滞，影响调焦的精度和调焦过程中的用户体验。两个径向面2132沿着倾斜槽213的径向延伸，两个径向面2132为弯曲方向相反的两个弧面，两个径向面2132向倾斜槽213两端的外侧弯曲。Referring to FIG. 23, the inner circumferential surface of the inclined groove 213 includes two circumferential faces 2131 and two radial faces 2132 connected between the two circumferential faces 2131. The two circumferential faces 2131 extend along the circumferential direction of the inclined groove 213, and the two circumferential faces 2131 are two planes parallel to each other, which can ensure that the positioning feature can smoothly move in the inclined groove 213, avoiding the positioning feature by the toggle. When the distance between the outer optical lens 212 and the inner optical lens 217 is adjusted, the positioning feature is stuck in the inclined groove 213, affecting the precision of focusing and the user experience in the focusing process. The two radial faces 2132 extend in the radial direction of the inclined groove 213, and the two radial faces 2132 are two arc faces opposite in the bending direction, and the two radial faces 2132 are bent toward the outside of both ends of the inclined groove 213.
由于定位特征件的外形呈圆柱状，如果将径向面2132设计成平面，则定位特征件移动至倾斜槽213的根部时，定位特征件与径向面2132之间为点接触，定位特征件易受到径向面2132施加的垂直方向的反作用力，使得定位特征件向相反方向产生一定的振动，影响调焦过程中的平稳性。并且，定位特征件向相反方向产生振动的同时，也可能会向相反方向产生一定的位移，导致外光学镜片212与内光学镜片217之间的距离与期望值产生偏差，降低调焦的精度。Since the shape of the positioning feature is cylindrical, if the radial surface 2132 is designed as a plane, when the positioning feature moves to the root of the inclined groove 213, the positioning feature and the radial surface 2132 are in point contact, and the positioning feature is The reaction force in the vertical direction which is easily applied by the radial surface 2132 causes the positioning feature to generate a certain vibration in the opposite direction, which affects the smoothness in the focusing process. Moreover, while the positioning feature generates vibration in the opposite direction, a certain displacement may be generated in the opposite direction, which causes the distance between the outer optical lens 212 and the inner optical lens 217 to deviate from the expected value, thereby reducing the precision of focusing.
因此，该种情况下，将两个径向面2132设置成向倾斜槽213两端的外侧弯 曲的弧面，可使得调焦过程中，当定位特征件移动至倾斜槽213的根部时，圆柱状外形的定位特征件与倾斜槽213端部的弯曲弧面相契合，弧面状的径向面2132与定位特征件的外周面的接触面积较大，使定位特征件平稳停靠在倾斜槽213的根部，保证调焦过程的平稳性，从而也有效提升调焦的精度。Therefore, in this case, the two radial faces 2132 are disposed as curved faces that are curved toward the outside of both ends of the inclined groove 213, so that the positioning feature moves to the root of the inclined groove 213 during the focusing process, and is cylindrical. The positioning feature of the shape is matched with the curved curved surface of the end of the inclined groove 213, and the contact area of the curved radial surface 2132 with the outer peripheral surface of the positioning feature is large, so that the positioning feature is smoothly stopped at the root of the inclined groove 213. To ensure the smoothness of the focusing process, and thus effectively improve the accuracy of focusing.

其中，内镜筒214设置于第二环状槽2111内部，内镜筒214的外径小于或等于第二环状槽2111的内径，以保证内镜筒214可安装至第二环状槽2111内。第二环状槽2111的深度大于内镜筒214的宽度，以保证内镜筒214可沿其轴向在外镜筒211内移动。The inner lens barrel 214 is disposed inside the second annular groove 2111, and the outer diameter of the inner lens barrel 214 is less than or equal to the inner diameter of the second annular groove 2111 to ensure that the inner lens barrel 214 can be mounted to the second annular groove 2111. Inside. The depth of the second annular groove 2111 is greater than the width of the inner barrel 214 to ensure that the inner barrel 214 is movable in the outer barrel 211 along its axial direction.
进一步地，内镜筒214的内壁顶部设置有第三环状槽2140。外光学镜片212设置于第一环状槽2110内，内光学镜片217设置于第三环状槽2140内。外光学镜片212和内光学镜片217均可以通过塑胶分别固定在第一环状槽2110和第三环状槽2140内，在固定的同时可起到防尘的作用。Further, a top end of the inner wall of the inner barrel 214 is provided with a third annular groove 2140. The outer optical lens 212 is disposed in the first annular groove 2110, and the inner optical lens 217 is disposed in the third annular groove 2140. Both the outer optical lens 212 and the inner optical lens 217 can be respectively fixed in the first annular groove 2110 and the third annular groove 2140 by plastic, and can play a dustproof role while being fixed.
在本实施例中，外光学镜片212和内光学镜片217为平凸透镜，外光学镜片212的平面侧朝向外镜筒211的顶部，内光学镜片217的平面侧朝向内镜筒214的顶部，外光学镜片212的凸面侧与内光学镜片217的平面侧相对设置。将外光学镜片212和内光学镜片217设置为平凸透镜，相比于双面凸起的凸透镜厚度更薄，更加节省空间，可将光学镜片调焦组件的在轴向上设置得更加轻薄，从而使整个头戴设备更加轻薄小巧，提升用户佩戴的舒适度。In the present embodiment, the outer optical lens 212 and the inner optical lens 217 are plano-convex lenses, the planar side of the outer optical lens 212 faces the top of the outer barrel 211, and the planar side of the inner optical lens 217 faces the top of the inner barrel 214, The convex side of the optical lens 212 is disposed opposite to the planar side of the inner optical lens 217. The outer optical lens 212 and the inner optical lens 217 are arranged as plano-convex lenses, which are thinner and more space-saving than the convex lenses of the double-sided protrusions, and the optical lens focusing assembly can be set to be lighter and thinner in the axial direction, thereby Make the entire headset lighter and smaller, and enhance the comfort of the user.
参阅图24，在本实施例中，第二环状槽2111的深度与内镜筒214的宽度之差满足：Referring to FIG. 24, in the present embodiment, the difference between the depth of the second annular groove 2111 and the width of the inner barrel 214 satisfies:
H>Sina×L，H>Sina×L,
其中，H为第二环状槽2111的深度与内镜筒214的宽度之差，a为倾斜槽213的周向面2131与外镜筒211端面的夹角，L为倾斜槽213在外镜筒211外周面上的长度。Sina×L即倾斜槽213在外镜筒211的轴向上所占据的长度，该长度决定了定位特征件在倾斜槽213内，沿着外镜筒211的轴向所能移动的最大距离，该距离等于本光学镜片调焦组件的最大调焦距离，因此，为了保证内镜筒214在外镜筒211内有足够的空间可以移动，需要保证第二环状槽2111的深度与内镜筒214的宽度之差大于本光学镜片调焦组件的最大调焦距离。Wherein, H is the difference between the depth of the second annular groove 2111 and the width of the inner barrel 214, a is the angle between the circumferential surface 2131 of the inclined groove 213 and the end surface of the outer barrel 211, and L is the inclined groove 213 in the outer barrel The length of the outer peripheral surface of 211. Sina×L is the length occupied by the inclined groove 213 in the axial direction of the outer barrel 211, and the length determines the maximum distance that the positioning feature can move along the axial direction of the outer barrel 211 in the inclined groove 213. The distance is equal to the maximum focusing distance of the optical lens focusing assembly. Therefore, in order to ensure that the inner barrel 214 has sufficient space to move in the outer barrel 211, it is necessary to ensure the depth of the second annular groove 2111 and the inner barrel 214. The difference in width is greater than the maximum focusing distance of the focusing component of the optical lens.
参阅图25，在本实施例中，内镜筒214为圆环状，前面的实施例中，凸台216的侧边容易跟外侧接触，可能导致内镜筒214卡死的情况发生，影响正常的调焦过程。如果通过涂布润滑油的方式避免卡死，则可能会导致润滑油在凸台216处汇集，甚至掉落到镜片上，导致镜片的脏污，因此，本实施例将内镜筒214设置为圆环状，可避免以上问题的产生。Referring to FIG. 25, in the embodiment, the inner lens barrel 214 has an annular shape. In the foregoing embodiment, the side of the boss 216 is easily in contact with the outer side, which may cause the inner lens barrel 214 to be stuck, which may affect the normal situation. The focusing process. If the seizing is avoided by applying the lubricating oil, the lubricating oil may be collected at the boss 216 or even dropped onto the lens, causing the lens to be dirty. Therefore, in the embodiment, the inner lens barrel 214 is set to The ring shape can avoid the above problems.
内镜筒214的周面设置有多个固定螺孔2141，多个固定螺孔2141沿着内镜筒214的周面均匀分布，固定螺孔2141的数量与倾斜槽213的数量相同，固定螺孔2141的位置与倾斜槽213的位置一一对应，定位特征件通过固定螺孔2141固定在内镜筒214的外壁。The circumferential surface of the inner lens barrel 214 is provided with a plurality of fixing screw holes 2141.

The number of fixing screw holes 2141 is the same as the number of the inclined grooves 213, and the fixing screw is fixed. The position of the hole 2141 is in one-to-one correspondence with the position of the inclined groove 213, and the positioning feature is fixed to the outer wall of the inner lens barrel 214 through the fixing screw hole 2141.
此外，参阅图26，为了保证整个调焦过程的正常进行，在调焦过程中两个极限位置下，即内镜筒214的最低点与外镜筒211的最低点在同一平面时，以及内镜筒214的最高点与外镜筒211的最高点在同一平面时，固定螺孔2141均位于倾斜槽213内。In addition, referring to FIG. 26, in order to ensure the normal progress of the entire focusing process, in the two extreme positions in the focusing process, that is, the lowest point of the inner barrel 214 and the lowest point of the outer barrel 211 are in the same plane, and When the highest point of the lens barrel 214 is in the same plane as the highest point of the outer barrel 211, the fixing screw holes 2141 are all located in the inclined groove 213.
参阅图25，结合图3，外镜筒211和内镜筒214的外部设置有镜框，镜框包括前壳1和与前壳1相扣合的后壳3，后壳3包括收纳腔46，外镜筒211和内镜筒214设置于收纳腔46内部；后壳3的底部设置有调节槽42，调节槽42的位置与一个倾斜槽213的位置相对应，调节槽42与倾斜槽213平行。调节槽42的形状与倾斜槽213的形状相同。Referring to FIG. 25, in conjunction with FIG. 3, the outer frame barrel 211 and the inner lens barrel 214 are externally provided with a frame, and the frame includes a front case 1 and a rear case 3 that is engaged with the front case 1. The rear case 3 includes a receiving cavity 46. The lens barrel 211 and the inner lens barrel 214 are disposed inside the housing chamber 46. The bottom of the rear housing 3 is provided with an adjustment groove 42. The position of the adjustment groove 42 corresponds to the position of one inclined groove 213, and the adjustment groove 42 is parallel to the inclined groove 213. The shape of the adjustment groove 42 is the same as that of the inclined groove 213.
定位特征件的最小长度小于或等于外镜筒211的壁厚，定位特征件的最大长度大于倾斜槽213处内镜筒214的外壁到后壳3的外壁之间的距离。The minimum length of the positioning feature is less than or equal to the wall thickness of the outer barrel 211, and the maximum length of the positioning feature is greater than the distance between the outer wall of the inner barrel 214 at the inclined groove 213 to the outer wall of the rear case 3.
当定位特征件为多个时，露出镜框外部的定位特征件起到供手指调节的作用，其余的镜框内部的定位特征件仅起到导向的作用，因此，为了避免镜框内部的定位特征件在转动过程中碰到外镜筒的其他器件，影响焦距的调节，将露出镜框外部的定位特征件的长度设置为最长，其余的定位特征件的长度均设置为相同的长度，且长度比露出镜框外部的定位特征件的长度短，使镜框内部的定位特征件保持在倾斜槽内，即使镜框内部的定位特征件凸出内镜筒的凸出部分的长度小于外镜筒镜壁的厚度。When there are a plurality of positioning features, the positioning feature that is exposed outside the frame serves to adjust the finger, and the positioning features inside the other frame only serve as a guide. Therefore, in order to avoid the positioning feature inside the frame During the rotation, other components of the outer lens barrel are touched, which affects the adjustment of the focal length, and the length of the positioning feature that is exposed outside the frame is set to be the longest, and the lengths of the remaining positioning features are all set to the same length, and the length ratio is exposed. The length of the positioning feature outside the frame is short, so that the positioning feature inside the frame is held in the inclined groove, even if the positioning feature inside the frame protrudes from the protruding portion of the inner barrel less than the thickness of the outer barrel wall.
为了利用露出镜框外部的定位特征件顺利完成调焦，首先定位特征件必须凸出镜框。由于镜框外部呈弧形，内镜筒外周面也呈弧形，在定位特征件从倾斜槽213的低点向高点移动过程中，需要该定位特征件的长度至少大于当调焦位置处于倾斜槽213最高点的情况下，此时内镜筒到镜框上倾斜槽213最高点的距离。In order to successfully perform the focusing using the positioning features that are exposed outside the frame, the positioning feature must first protrude from the frame. Since the outer surface of the lens frame is curved, the outer peripheral surface of the inner lens barrel is also curved. During the movement of the positioning feature from the low point to the high point of the inclined groove 213, the length of the positioning feature is required to be at least greater than when the focusing position is inclined. In the case where the groove 213 is the highest point, the distance from the inner lens barrel to the highest point of the inclined groove 213 on the frame is at this time.
在本实施例中，倾斜槽213和定位特征件的数量为三个，三个定位特征件中，其中一个定位特征件穿过倾斜槽213和调节槽42伸出至后壳3的外部；另外两 个定位特征件分别伸入对应的倾斜槽213。伸出至后壳3的外部的定位特征件的长度大于倾斜槽213处内镜筒214的外壁到后壳3的外壁之间的距离，另外两个定位特征件的长度小于或等于外镜筒211的壁厚。其中，三个倾斜槽在外镜筒211上的倾斜方向一致，三个倾斜槽的低点和高点均在同一个面上，定位特征件在外镜筒211上均匀分布，可以保证调节内镜筒214时，内镜筒214整体受力均匀，避免只设置一个倾斜槽213和定位特征件时，内镜筒214上靠近定位特征件的部分先产生运动，远离定位特征件的部分运动滞后，从而导致调解过程卡顿，不顺滑，影响用户体验。In this embodiment, the number of the inclined grooves 213 and the positioning features is three, and one of the three positioning features protrudes from the inclined groove 213 and the adjustment groove 42 to the outside of the rear case 3; The two positioning features respectively extend into the corresponding inclined grooves 213. The length of the positioning feature extending to the outside of the rear case 3 is greater than the distance between the outer wall of the inner barrel 214 at the inclined groove 213 to the outer wall of the rear case 3, and the length of the other two positioning features is less than or equal to the outer barrel The wall thickness of 211. Wherein, the inclination directions of the three inclined grooves on the outer barrel 211 are the same, the low points and the high points of the three inclined grooves are all on the same surface, and the positioning features are evenly distributed on the outer barrel 211, so that the adjustment of the inner tube can be ensured. At 214, the inner lens barrel 214 is uniformly stressed. When only one inclined groove 213 and the positioning feature are disposed, the portion of the inner lens barrel 214 near the positioning feature first moves, and the movement away from the positioning feature is delayed. The mediation process is stuck, not smooth, affecting the user experience.
参阅图27，由于外镜筒211顶部需要设置外光学镜片212，因此，倾斜槽213顶部与外镜筒211顶部需要预留出一定的距离，倾斜槽213靠近镜框顶部的一端到外镜筒211顶部端面的距离M1为外镜筒211宽度M的50％～55％，倾斜槽213靠近镜框底部的一端到外镜筒211底部端面的距离M2为外镜筒211宽度的20％～25％，在保证本光学镜片调焦组件的调焦距离的前提下，减小光学镜片调焦组件的厚度。此外，倾斜槽213的最低点高于固定螺孔2141在内镜筒214上距离内镜筒214底部的高度，倾斜槽213的最高点要低于内镜筒214与外镜筒211顶部接触时，外镜筒211的整体高度与固定螺孔2141在内镜筒214上距内镜筒214顶部的高度之差。Referring to FIG. 27, since the outer optical lens 212 needs to be disposed at the top of the outer lens barrel 211, a certain distance needs to be reserved between the top of the inclined groove 213 and the top of the outer lens barrel 211, and the inclined groove 213 is adjacent to the end of the top of the lens frame to the outer lens barrel 211. The distance M1 of the top end surface is 50% to 55% of the width M of the outer barrel 211, and the distance M2 of the inclined groove 213 from the end of the bottom of the frame to the bottom end surface of the outer barrel 211 is 20% to 25% of the width of the outer barrel 211. The thickness of the optical lens focusing assembly is reduced under the premise of ensuring the focusing distance of the focusing component of the optical lens. In addition, the lowest point of the inclined groove 213 is higher than the height of the fixed screw hole 2141 on the inner lens barrel 214 from the bottom of the inner lens barrel 214, and the highest point of the inclined groove 213 is lower than when the inner lens barrel 214 is in contact with the top of the outer lens barrel 211. The overall height of the outer barrel 211 is different from the height of the fixing screw hole 2141 on the inner barrel 214 from the top of the inner barrel 214.
