Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

Please refer to FIG. 1 to FIG. 5 , the present application discloses a photographing device, including a lens 100 and a photosensitive chip 600 . Wherein the lens 100 and the photosensitive chip 600 can be sequentially arranged along the optical axis direction of the lens 100, so that ambient light can freely enter and exit the shooting device through the lens 100, and then the photosensitive chip 600 converts the light signal into an electrical signal, thereby realizing the shooting and imaging of the shooting device .

The photographing device also includes a base plate 700 , a focusing transmission part 500 , an anti-shake transmission part 800 and a first driving part 900 . The substrate 700 is the installation basis and movement basis of the relevant components in the photographing device of the present application, and the focusing transmission part 500 , the photosensitive chip 600 and the anti-shake transmission part 800 can all be arranged on the substrate 700 .

The first driving member 900 can provide the driving force required for shooting, and the focus transmission member 500 and the anti-shake transmission member 800 are used to transmit the driving force. Specifically, the first driving member 900 can be drivingly connected to the focusing transmission member 500 and the anti-shake transmission member 800 respectively, so that the corresponding parts in the shooting device can be generated through the transmission driving force of the focusing transmission member 500 and the shaking transmission member 800. The required movement mode, and then realize the zoom or anti-shake of the shooting device, the following introduces the movement principle:

When the first driving part 900 drives the anti-shake transmission part 800 to move, the substrate 700 can move with the anti-shake transmission part 800, and the photosensitive chip 600 can perform anti-shake movement with the substrate 700. The plane movement of the 100 optical axis compensates for the abnormal shaking during shooting, so that the ambient light is always projected to the fixed position on the photosensitive chip 600, ensuring the required shooting quality.

When the first driving member 900 drives the focus transmission member 500 to move, the substrate 700 will move with the focus transmission member 500, and the photosensitive chip 600 can perform focus movement with the substrate 700. The direction of the focus movement is different from the anti-shake movement, such as The focus movement is along the optical axis of the lens 100, so that the distance between the photosensitive chip 600 and the lens 100 will be changed through the focus movement, so as to realize the focus during shooting, thereby ensuring the normal progress of the shooting work.

To sum up, the shooting device of this application can simultaneously take into account the anti-shake movement and focusing movement required for shooting to ensure better imaging quality, and this application uses the method of driving the photosensitive chip 600 to realize shooting anti-shake and focusing, which is relatively easy. In terms of the way of driving the lens, the photosensitive chip 600 is small in size and light in weight, which can reduce the power consumed in the process of anti-shake and focusing, and reduce the volume of the anti-shake mechanism and the focus mechanism, thereby enabling the further miniaturization of the shooting device , and the electronic equipment installed with the camera device of the present application can also be further thinned, which is very suitable for smart phones and other electronic equipment with small volume and high integration of parts.

At the same time, it should be pointed out that both the focusing transmission part 500 and the anti-shake transmission part 800 are moved through the first driving part 900, which can realize the multiplexing of the first driving part 900, improve the integration degree of the shooting device, and further make the The camera device is further miniaturized and thinned.

More specifically, as shown in FIG. 4 , the anti-shake transmission member 800 may include a plurality of first anti-shake transmission members 801 and a plurality of second anti-shake transmission members 802 . A plurality of first anti-shake transmission members 801 can be arranged along the first direction X, and the plurality of first anti-shake transmission members 801 are symmetrically arranged on both sides of the photosensitive chip 600 . A plurality of second anti-shake transmission members 802 can be arranged along the second direction Y, and the plurality of second anti-shake transmission members 802 are symmetrically arranged on both sides of the photosensitive chip 600 . The first direction X, the second direction Y and the direction of the optical axis of the lens 100 intersect two by two. Such an arrangement is for controlling the anti-shake movement direction of the photosensitive chip 600 , which will be described in detail below.

When the first driving member 900 drives multiple first anti-shake transmission members 801 to move simultaneously, the driving force given to the substrate 700 by the multiple first anti-shake transmission members 801 is symmetrical to both sides of the photosensitive chip 600, so that The resultant force of the first anti-shake transmission parts 801 on the substrate 700 will move along the first direction X, and then the substrate 700 will move along the first direction X along with the plurality of first anti-shake transmission parts 801, and the photosensitive chip 600 can move along with the substrate 700. Translational movement in the first direction X.

When the first driving member 900 drives multiple second anti-shake transmission members 802 to move, the driving force given to the substrate 700 by the multiple second anti-shake transmission members 802 is symmetrical to the two sides of the photosensitive chip 600, so that multiple The resultant force of the second anti-shake transmission member 802 on the substrate 700 will be along the second direction Y, and then the substrate 700 will move along the second direction Y along with the plurality of second anti-shake transmission members 802, and the photosensitive chip 600 can move along the second direction Y along with the substrate 700. Translational movement in two directions Y. That is, the anti-shake movement of the photosensitive chip 600 includes translational movement along the first direction X and translational movement along the second direction Y.

The plurality of first anti-shake transmission members 801 and the plurality of second anti-shake transmission members 802 can also enable the photosensitive chip 600 to perform anti-shake rotation, as shown in FIG. 5 . In the case where the first driving member 900 drives the first anti-shake transmission member 801 located on one side of the photosensitive chip 600 to move, or the first driving member 900 drives the second anti-shake transmission member 802 located on one side of the photosensitive chip 600 In the case of motion, the driving force given to the substrate 700 by the first anti-shake transmission member 801 or the second anti-shake transmission member 802 is only located on one side of the photosensitive chip 600. Under the action of such a one-sided driving force, the substrate 700 will be subjected to a torque around the optical axis of the lens 100 , so as to rotate around the optical axis of the lens 100 , and the photosensitive chip 600 can rotate around the optical axis of the lens 100 along with the substrate 700 .

Of course, as shown in FIG. 5, the first anti-shake transmission member 801 and the second anti-shake transmission member 802 located on one side of the photosensitive chip 600 can also be driven simultaneously. The direction of the resultant force generated by the component 802 forms a certain angle with the first direction X and the second direction Y. Under the action of this resultant force, the substrate 700 will also form a torque around the optical axis of the lens 100, so that the photosensitive chip 600 can follow the The substrate 700 rotates around the optical axis of the lens 100 .

To sum up, the anti-shake motion of the photosensitive chip 600 will be composed of a translational motion along the first direction X, a translational motion along the second direction Y, and a rotational motion around the optical axis of the lens 100 to achieve a better anti-shake effect.

More specifically, the first direction X, the second direction Y, and the direction of the optical axis of the lens 100 can be perpendicular to each other to form a three-dimensional coordinate system, so that the photosensitive chip 600 will perform anti-shake movement on a plane perpendicular to the optical axis of the lens 100, so that During the shooting process, when shaking occurs, it is easier to calculate the compensation amount of shaking, and then it is easier to control the direction and stroke of the anti-shake movement.

Furthermore, as shown in FIG. 4 and FIG. 5 , there may be two first anti-shake transmission members 801 and two second anti-shake transmission members 802 . Two first anti-shake transmission parts 801 are symmetrically arranged on both sides of the photosensitive chip 600, and two second anti-shake transmission parts 802 are symmetrically arranged on both sides of the photosensitive chip 600, so that while ensuring the anti-shake effect of the photosensitive chip 600, the The number of the first anti-shake transmission member 801 and the second anti-shake transmission member 802 is the least, thereby reducing the volume of the photographing device.

For the anti-shake movement and focusing movement of the photosensitive chip 600, any driving mechanism can be used to realize it, such as a screw cooperation mechanism to drive the photosensitive chip 600 to achieve focusing, and a miniature cylinder assembly to achieve anti-shake, etc. The device of the present application is shown in Figure 1 As shown in FIG. 3 , the substrate 700 can be set as a circuit board, and the photosensitive chip 600 and the substrate 700 are electrically connected to realize power supply for the operation of the photosensitive chip 600 .

In this way, the electric energy can be transmitted to the focus transmission member 500 through the substrate 700, and then electromagnetic drive is performed between the first drive member 900 and the focus transmission member 500, so that the focus transmission member 500 is driven along the optical axis direction of the lens 100, thereby enabling The substrate 700 moves along the optical axis of the lens 100 , and the photosensitive chip 600 can move along with the substrate 700 to focus.

Electric energy can also be transmitted to the anti-shake transmission part 800 through the substrate 700, and then the first drive part 900 and the anti-shake transmission part 800 are electromagnetically driven, so that the anti-shake transmission part 800 is received from the first direction X and/or the second direction X. The driving force in the two directions Y further makes the substrate 700 perform translational motion along the first direction X or the second direction Y, or rotate around the optical axis of the lens 100 , and the photosensitive chip 600 can perform anti-shake motion along with the substrate 700 .

The above arrangement realizes the multiplexing of the substrate 700. The substrate 700 is not only the carrier of the photosensitive chip 600, the focus transmission part 500 and the anti-shake transmission part 800, but also serves as a power supply medium for the photosensitive chip 600, the focus transmission part 500 And the anti-shake transmission part 800 supplies power.

The anti-shake transmission part 800 can be used in conjunction with the second sensor 810, and the second sensor 810 can also be arranged on the substrate 700 and powered by the substrate 700. The second sensor 810 can be used to detect the anti-shake movement of the photosensitive chip 600. stroke, to prevent excessive motion of the photosensitive chip 600 during anti-shake motion.

The focusing transmission member 500 , the anti-shake transmission member 800 and the first driving member 900 are arranged in sequence along the optical axis of the lens 100 . Such a layout is more convenient for the first driving member 900 to apply driving force to the focusing transmission member 500 and the anti-shake transmission member 800 .

The photographing device also includes a carrier frame 400 and a movable body 410 . The carrier frame 400 is movably connected to the substrate 700 through the movable body 410 . The setting of the carrier frame 400 can constrain the movement path of the substrate 700 so as to better control the direction of the focus movement or anti-shake movement of the photosensitive chip 600 , and the setting of the movable body 410 can make the substrate 700 move relative to the carrier frame 400 The movement can be more smooth, so as to avoid jamming between the substrate 700 and the carrier frame 400 , thereby ensuring the effectiveness of the focus movement or anti-shake movement of the photosensitive chip 600 . Specifically, the carrier frame 400 can be sleeved on the substrate 700 , and the movable body 410 can be arranged between the carrier frame 400 and the substrate 700 .

In this way, the movable body 410 can better prevent jamming between the carrier frame 400 and the substrate 700 . Furthermore, there may be multiple ball sets, and the ball sets are located between the corners of the substrate 700 and the corners of the carrier frame 400, so that the movement of the substrate 700 is smoother.

More specifically, both the corners of the substrate 700 and the corners of the carrier frame 400 can be rounded, and the cooperation of the two will form a circular track, so that the movable body 410 of the ball structure will be located in the circular track, better ensuring the substrate The movement of the 700 is smooth, thereby ensuring the effectiveness of the movement of the photosensitive chip 600.

More specifically, the photographing device may further include a casing 200 .
