The adjusting component 30 and the image generating module 20 apply a force to the fixed shaft 21 through the sliding slot 31, and the two cooperate with each other to realize the relative movement of the image generating module 20 and the lens module 10.
在某些实施方式中，图像产生模组20包括顶壁和自顶壁沿垂直方向延伸的两侧壁，固定轴21设置在图像产生模组20的两侧壁上。如此，可使得图像产生模组20的受力点位于模组的两侧，相对于受力点位于顶壁的设计，模组整体受力均匀，可有效防止施力点集中导致图像产生模组20在移动中可能发生的偏转，进而由偏转带来的倾斜致使产生的图像发生形变，影响观影效果。In some embodiments, the image generation module 20 includes a top wall and two side walls extending in a vertical direction from the top wall, and the fixed shaft 21 is disposed on both sidewalls of the image generation module 20. In this way, the force receiving point of the image generating module 20 can be located on both sides of the module, and the overall force of the module is uniform with respect to the design of the force receiving point on the top wall, which can effectively prevent the concentration of the force applying points from being caused by the image generating module 20 . The deflection that may occur during the movement, which in turn causes the resulting image to be deformed by the tilt caused by the deflection, affects the viewing effect.
进一步地，在某些实施方式中，固定轴21与图像产生模组20的中心轴位于同一水平面上。可以理解，固定轴21的位置固定，作为受力点驱动图像产生模组20移动，当固定轴21与中心轴位于同一水平面时，可使得图像产生模组20所受的驱动力关于中心轴对称，在受力均匀的情况下，图像产生模组20 能够保证在移动方向上的平稳运动而不会发生偏转。Further, in some embodiments, the fixed shaft 21 is on the same horizontal plane as the central axis of the image generation module 20. It can be understood that the position of the fixed shaft 21 is fixed, and the image generating module 20 is driven as a force receiving point. When the fixed shaft 21 and the central axis are at the same horizontal plane, the driving force of the image generating module 20 can be made symmetric about the central axis. , in the case of uniform force, the image generation module 20 It is possible to ensure smooth movement in the moving direction without deflection.
在一些示例中，当固定轴21的数量为2个时，每个侧壁包括有1个固定轴21，该固定轴21位于侧壁的中心轴线上。在另一些示例中，固定轴21的数量可以是多个，其数量应当为偶数个，且每个侧壁的偶数个固定轴21应当关于侧壁的中心轴对称。In some examples, when the number of the fixed shafts 21 is two, each side wall includes one fixed shaft 21 which is located on the central axis of the side wall. In other examples, the number of fixed shafts 21 may be plural, the number of which should be an even number, and the even number of fixed shafts 21 of each side wall should be symmetrical about the central axis of the side wall.
其中，固定轴21可与图像产生模组20的壳体一体成型，也可以是分体制造进行组装，在此不做限制。The fixed shaft 21 may be integrally formed with the housing of the image generating module 20, or may be assembled separately, and is not limited herein.
在某些实施方式中，滑槽31相对图像产生模组20倾斜设置。In some embodiments, the chute 31 is disposed obliquely relative to the image generation module 20.
可以理解地，当对调节组件30施力进而带动滑槽31移动时，倾斜设置可使得滑槽31对固定轴21施力，进而驱动图像产生模组20移动。在这样的实施方式中，调节组件30的设置方向与图像产生模组20的移动方向垂直，也即是说，当调节组件30沿垂直于图像产生模组20中心轴方向移动时，可驱动图像产生模组20沿中心轴方向移动。It can be understood that when the adjusting component 30 is biased to drive the sliding slot 31 to move, the tilting arrangement can cause the sliding slot 31 to apply force to the fixed shaft 21 to drive the image generating module 20 to move. In such an embodiment, the orientation of the adjustment assembly 30 is perpendicular to the direction of movement of the image generation module 20, that is, when the adjustment assembly 30 is moved perpendicular to the central axis of the image generation module 20, the image can be driven. The generating module 20 is moved in the direction of the central axis.
在某些实施方式中，镜头模组10包括镜筒以及镜片组件。镜片组件包括有一个或多个镜片。镜筒通常具有入射口及出射口，入射口面向图像产生模组20的一侧，进入入射口的光线通过镜片组件并发生折射与反射，最终从出射***出。一般地，图像产生装置20包括有显示器，例如LED显示器或OLED显示器，并且，显示器设置在入射口上。如此，显示器显示的图像的光线进入入射口，并由镜片组向预定的方向投射，从出射***出的光线进人眼，人眼将能看到显示器显示的图像的放大虚像。In some embodiments, the lens module 10 includes a lens barrel and a lens assembly. The lens assembly includes one or more lenses. The lens barrel usually has an entrance port and an exit port. The entrance port faces the side of the image generating module 20. The light entering the entrance port passes through the lens assembly and is refracted and reflected, and finally is emitted from the exit port. Generally, the image generating device 20 includes a display such as an LED display or an OLED display, and the display is disposed on the entrance port. In this way, the light of the image displayed by the display enters the entrance port and is projected by the lens group in a predetermined direction, and the light emitted from the exit port enters the human eye, and the human eye will be able to see the enlarged virtual image of the image displayed by the display.
在某些实施方式中，显示装置100还包括固定板40，固定板40与镜头模组10固定连接。In some embodiments, the display device 100 further includes a fixing plate 40 that is fixedly coupled to the lens module 10 .
固定板40与镜头模组10可通过螺钉、卡扣等方式固定连接，当然还可以粘接等方式，在此不做限制。具体地，固定板40与镜筒固定连接。可以理解，用户通过镜头模组10观看影像，因此，镜头模组10与图像产生模组20间的相对移动也即是镜头模组10固定，而图像产生模组20移动。 The fixing plate 40 and the lens module 10 can be fixedly connected by screws, buckles, etc., of course, can also be bonded or the like, and is not limited herein. Specifically, the fixing plate 40 is fixedly coupled to the lens barrel. It can be understood that the user views the image through the lens module 10. Therefore, the relative movement between the lens module 10 and the image generation module 20 is that the lens module 10 is fixed, and the image generation module 20 moves.
在某些实施方式中，镜筒的两侧壁还设置有凸块11，凸块11开设有滑轨12。In some embodiments, the two side walls of the lens barrel are further provided with a bump 11 , and the bump 11 is provided with a slide rail 12 .
在这样的实施方式中，调节组件30还包括有活动部32，活动部32罩设图像产生模组20，活动部32包括有顶壁和自顶壁两侧沿垂直方向延伸的两侧壁，滑槽31开设于活动部32的两侧壁。In such an embodiment, the adjustment assembly 30 further includes a movable portion 32 that covers the image generation module 20, and the movable portion 32 includes a top wall and two side walls extending in a vertical direction from both sides of the top wall. The chute 31 is formed on both side walls of the movable portion 32.
进一步地，活动部32的两侧壁还形成有凸肋33，凸肋33与滑轨12配合。Further, the two side walls of the movable portion 32 are further formed with ribs 33, and the ribs 33 are engaged with the slide rails 12.
具体地，滑槽31与固定轴21配合，固定轴21位于图像产生模组20的两侧壁，相应的，滑槽31位于活动部32的两侧壁。对调节组件30施力也即是对活动部32施力，受力后，活动部32可以沿与图像产生模组20中心轴垂直的方向移动，并通过滑槽31对固定轴21施力，继而驱动图像产生模组20移动。Specifically, the sliding slot 31 is engaged with the fixed shaft 21, and the fixed shaft 21 is located at two sidewalls of the image generating module 20. Correspondingly, the sliding slot 31 is located at both sidewalls of the movable portion 32. The force applied to the adjustment assembly 30 is to apply force to the movable portion 32. After the force is applied, the movable portion 32 can move in a direction perpendicular to the central axis of the image generation module 20, and the fixed shaft 21 is biased by the sliding groove 31, and then The image generation module 20 is driven to move.
可以理解，活动部32仅通过滑槽31和固定轴21配合，在移动过程中可能会产生偏转，并且活动部32自身可以转动，不利于调节。因此，凸肋33与滑轨12配合可起到限位作用，使得活动部32的移动稳定而不发生偏转，并限制活动部32仅能够沿某一预定方向移动。操作时，活动部32带动凸肋33，凸肋33在滑轨12的限定下沿预定方向移动。It can be understood that the movable portion 32 is only engaged by the sliding groove 31 and the fixed shaft 21, and deflection may occur during the movement, and the movable portion 32 itself may be rotated, which is disadvantageous for adjustment. Therefore, the engagement of the rib 33 with the slide rail 12 can serve as a limit, so that the movement of the movable portion 32 is stabilized without deflection, and the movable portion 32 is restricted from being movable only in a predetermined direction. In operation, the movable portion 32 drives the rib 33, and the rib 33 moves in a predetermined direction under the restriction of the slide rail 12.
在某些实施方式中，固定板40形成有限位件41，限位件41与镜头模组10的光轴方向垂直。In some embodiments, the fixing plate 40 forms a limiting member 41 that is perpendicular to the optical axis direction of the lens module 10.

具体地，与凸肋33与滑轨12的配合相类似地，限位件41与通孔34相配合也能够增加活动部32在移动过程中的稳定性。限位件41可具有一定的高度，其高度可与活动部32的行程相当。Specifically, similarly to the cooperation of the rib 33 and the slide rail 12, the engagement of the stopper 41 with the through hole 34 can also increase the stability of the movable portion 32 during the movement. The limiting member 41 can have a height that is comparable to the stroke of the movable portion 32.
固定板40与镜头模组10固定连接，镜头模组10与图像产生模组20活动连接，调节组件30可活动的设置于固定板40上方，并可驱动图像产生模组20移动，镜头模组10和图像产生模组20位于固定板40的下方，或者说，调 节组件30与图像产生模组20分别位于固定板40的两侧。The fixing plate 40 is fixedly connected to the lens module 10, the lens module 10 is movably connected to the image generating module 20, and the adjusting component 30 is movably disposed above the fixing plate 40, and can drive the image generating module 20 to move, the lens module 10 and the image generation module 20 is located below the fixed plate 40, or The node assembly 30 and the image generation module 20 are respectively located on both sides of the fixed plate 40.
在一些实施方式中，固定板40的上表面可以平齐。在另一些示例中，也可以将固定板40制作成阶梯状，其中，在保证强度的基础上，固定板40的厚度可自镜头模组10一侧向图像产生模组20一侧减小，厚度较小的一侧形成有限位件41，活动部32通过通孔34与限位件41罩设在固定板40上，从而降低了图像产生模组20一侧的整体高度，使得电子装置1000的整体更加轻薄。In some embodiments, the upper surface of the fixed plate 40 can be flush. In other examples, the fixing plate 40 may be formed in a stepped shape, wherein the thickness of the fixing plate 40 may be reduced from the side of the lens module 10 toward the side of the image generating module 20 on the basis of ensuring the strength. The smaller thickness side forms a limiting member 41, and the movable portion 32 is covered on the fixing plate 40 through the through hole 34 and the limiting member 41, thereby reducing the overall height of the image generating module 20 side, so that the electronic device 1000 The whole is lighter and thinner.
在某些实施方式中，活动部32还包括有转轴35，调节组件30还包括旋钮36，旋钮36与转轴35螺纹连接。如此，转动旋钮36将带动活动部32移动，进而驱动图像产生模组20移动。旋钮36的施力面积相较于转轴35的端部更大，方便用户操作。In some embodiments, the movable portion 32 further includes a rotating shaft 35. The adjusting assembly 30 further includes a knob 36, and the knob 36 is screwed to the rotating shaft 35. In this way, turning the knob 36 will drive the movable portion 32 to move, thereby driving the image generating module 20 to move.
