[0039] A zoom lens is a camera lens that can change its focal length within a certain range, thereby obtaining different widths of field angles, different sizes of images, and different ranges of scenery. A zoom lens can change the shooting range by changing the focal length without changing the shooting distance, so it is very helpful for picture composition. Since a zoom lens can also play the role of several fixed-focus lenses, it not only reduces the number of photographic equipment carried when traveling, but also saves time for changing lenses. Most existing zoom lenses are large in size, making the shooting equipment inconvenient to carry and heavy in weight, so during a long period of photography, the photographer will be more tired. There are also some smaller zoom lenses, but they are more expensive.

[0040] In view of this, the present invention provides an installation structure, a lens and a shooting device of a magnetic structure of a VCM motor. No limitation is made here. As long as the installation structure has the magnetic structure of the VCM motor, it can be understood as the shooting device to be protected by the present invention. Figures 1 to 4 An embodiment of the installation structure of the magnet structure of the VCM motor provided by the present invention.

[0041] Please refer to Figure 1 and Figure 4 The mounting structure 100 of the magnet structure 2 of the VCM motor is used in a lens, and comprises: a frame 1 and a magnet structure 2, wherein the frame 1 defines a mounting channel 13 for movably mounting a lens assembly provided with a coil a, and the mounting channel 13 extends in an up-down direction, and a mounting hole 11 is penetrated through one side wall of the frame 1; the magnet structure 2 is mounted in the mounting hole 11, and the outer end of the magnet structure 2 is adapted to the mounting hole 11, and the inner end of the magnet structure 2 extends into the frame 1, and a magnetic field is formed in the frame 1; wherein, when the coil a is energized, the magnetic field generated by the magnet structure 2 drives the coil a to drive the lens assembly to move up and down.

[0042] In the technical solution of the present invention, a mounting channel 13 for movably mounting the lens assembly of coil a is provided in the frame 1, and the mounting channel 13 extends in the up and down directions. A mounting hole 11 is penetrated through a side wall of the frame 1, and the magnet assembly 23 is installed in the mounting hole 11 until the inner end of the magnet assembly 23 extends into the frame 1, and the magnet assembly 23 forms a magnetic field in the frame 1. When coil a is energized, the magnetic field generated by the coil a and the magnetic field generated by the magnet assembly 23 interact with each other, thereby driving the coil a to drive the lens assembly to move up and down. Such an embedded mounting structure can reduce the internal volume of the lens while ensuring that the lens can be flexibly focused, thereby reducing the volume of the lens, saving materials and costs.

[0043] Reference Figure 2 In the present embodiment, the mounting hole 11 is set as an elongated hole, the length direction of the elongated hole is up and down, and the width direction of the elongated hole is left and right. In order to fix the magnet structure 2 in the mounting channel 13 of the frame 1, the magnet structure 2 includes a mounting member 21 and a magnet assembly 23. The magnet assembly 23 is connected to the mounting member 21, and the mounting member 21 is adapted to the mounting hole 11. The mounting member 21 is fixedly connected to the side wall of the frame 1. At this time, the magnet assembly 23 extends into the frame 1, and the magnet assembly 23 generates a magnetic field in the frame 1. In this way, the magnet assembly 23 can be fixed in the mounting channel 13 while maintaining the normal generation of the magnetic field by the magnet assembly 23. The structure is simple and space saving.

[0044] Further, see Figure 2 and Figure 3In order to firmly install the magnet assembly 23 in the frame 1, the mounting member 21 includes two first sides and two second sides, the two first sides are distributed in the up-down direction, the two second sides are extended in the up-down direction, each second side is connected with a mounting plate 22, and when the mounting member 21 is installed on the frame 1 in conjunction with the mounting hole 11, the two mounting plates 22 are fixedly connected to the side wall of the frame 1 and fit the side wall of the frame 1, so that the magnet assembly 23 can be firmly installed in the frame 1, the structure is firm, and the service life is long.

[0045] Furthermore, in order to install the two mounting plates 22 on the outer wall of the frame 1, the two mounting plates 22 are each provided with a mounting portion, and the frame 1 is correspondingly provided with a matching portion that cooperates with the mounting portion, and the matching portion and the mounting portion are connected to each other, so that the two mounting plates 22 are installed on the outer wall of the frame 1.

[0046] Specifically, refer to Figure 2 and Figure 4 In this embodiment, the mounting portion is set as a fixing hole 223, and the corresponding matching portion is set as a matching hole 141. When the mounting plate 22 is installed on the side wall of the frame 1, the matching hole 141 and the corresponding fixing hole 223 are opposite and roughly coaxial. The screws are passed through the matching holes 141 and the fixing holes 223 and then tightened, and the mounting plate 22 is fixedly installed on the outer wall of the frame 1. This is easy to operate and has a simple structure.

[0047] In order to prevent the mounting member 21 from being offset when being mounted on the frame 1, refer to Figure 2 , because only by screwing through the fixing hole 223 and the corresponding matching hole 141 to fix, deviation may occur, resulting in the process of the coil a driving the lens assembly to move up and down being affected, the fixing hole 223 is provided with a plurality of, the corresponding part of the matching portion is set as the matching hole 141, the other part of the matching portion is set as the matching column 142, and the matching column 142 extends toward the outside of the frame 1, when the mounting member 21 is installed on the frame 1, the matching column 142 is first inserted into the corresponding part of the matching hole 141, which can limit the left and right deviation of the mounting plate 22, at this time, because the matching column 142 and the matching hole 141 are both set with the corresponding fixing hole 223, when the matching column 142 is inserted into the corresponding part of the fixing hole 223, the matching hole 141 corresponds to the other part of the fixing hole 223, and then the screw is passed through the matching hole 141 and the fixing hole 223 to tighten, and the installation of the mounting member 21 is completed, so that the installation accuracy is improved and the quality is guaranteed.

[0048] In this embodiment, refer to Figure 4 In order to reduce weight, the two mounting plates 22 are divided into a first mounting plate 221 and a second mounting plate 222. The area of ​​the first mounting plate 221 is larger than that of the second mounting plate 222, and the matching column 142 is penetrated through the first mounting plate 221. The first mounting plate 221 and the second mounting plate 222 are both provided with a plurality of fixing holes 223. When the mounting plate 22 is installed on the side wall of the frame 1, the matching column 142 is penetrated through the first mounting plate 221, and the number of mounting points on the first mounting plate 221 increases, and the area of ​​the first mounting plate 221 also increases. The areas of the first mounting plate 221 and the second mounting plate 222 change with the number of the set mounting points. While ensuring the stable and accurate installation of the mounting plate 22, the present application saves the use of materials, reduces weight, and saves costs.

[0049] In this embodiment, refer to Figure 2 The mounting hole 11 includes two third sides and two fourth sides, the two third sides are distributed in the up-down direction, and the two fourth sides are distributed in the left-right direction. A limiting plate 12 is provided on the two fourth sides of the mounting hole 11, and the limiting plate 12 extends toward the frame 1, and the length of the limiting plate 12 toward the frame 1 is not longer than the thickness of the magnet assembly 23 along the extension direction of the limiting plate 12 when installed in the frame 1, so that the limiting plate 12 can further limit the position of the magnet assembly 23 to prevent the magnet assembly 23 from shifting left and right, and at the same time does not hinder the installation of other components. Such a setting can achieve more precise installation and improve accuracy.

[0050] In this embodiment, refer to Figure 3 and Figure 4 In order to generate a magnetic field, the magnet assembly 23 includes a yoke 231 and a magnet 232. The yoke 231 is arranged in a ring shape surrounding the left and right directions, and a through hole extending in the left and right directions is formed. The magnet 232 is installed on the inner wall of the through hole and forms a closed magnetic field together with the yoke 231. The coil a is partially located in the through hole, and the winding direction of the coil a is perpendicular to the length direction of the through hole. After the coil a is energized, the coil a can move in the through hole through the influence of the mutual magnetic field, thereby ensuring normal operation, and the structure is simple and the cost is low.

[0051] The present invention also provides a lens, including an installation structure 100 of the magnet structure 2 of the VCM motor. The installation structure 100 of the magnet structure 2 of the VCM motor is specifically referred to the above embodiment and will not be described in detail here. After the coil a is energized, the coil a can move in the through hole through the influence of the mutual magnetic field, thereby zooming the lens. The lens configured in this way maintains the original zoom technology with a smaller size, lower cost and greater practicality.

[0052] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
