[0034] See also Figures 3 to 6 The imaging device 100 includes a housing 10 and a first lens module 20 . The first lens module 20 is received and installed in the housing 10 .

[0035] The housing 10 includes a base plate 11 and a side plate 12 mounted on the base plate 11. A slide groove 125 is defined in the side plate 12. The first lens module 20 includes a housing 21 and a lens assembly 22. The lens assembly 22 is mounted on the housing 21. The housing 21 includes a main body 211 and a slider 212 connected to the main body 211. The slide groove 125 extends parallel to the optical axis O of the lens assembly 22. The slider 212 is slidably mounted within the slide groove 125. Sliding the housing 21 drives the lens assembly 22 with it.

[0036] The slider 212 matches the shape of the slide groove 125. For example, the slide groove 125 is a rectangular groove and the slider 212 is a rectangular block. That is, the slide groove 125 and the slider 212 are perpendicular to the optical axis O ( Figure 3 The cross-sections of the surfaces parallel to the VII-VII line in the figure, and the explanations thereof are the same as those below) are all rectangular; or, the slide groove 125 is a semicircular groove, and the slider 212 is a semicircular block, that is, the cross-sections of the slide groove 125 and the slider 212 cut by the surface perpendicular to the optical axis O are semicircular; or, the slide groove 125 is a rectangular groove, and the slider 212 is a semicircular block, that is, the cross-sections of the slide groove 125 cut by the surface perpendicular to the optical axis O are rectangular, and the cross-sections of the slider 212 cut by the surface perpendicular to the optical axis O are semicircular; of course, the cross-sections of the slide groove 125 and the slider 212 cut by the surface perpendicular to the optical axis O can also be other shapes, such as other regular shapes or irregular special shapes, as long as the slider 212 can cooperate with the slide groove 125 to slide in the slide groove 125, which will not be elaborated here. In this embodiment, the cross-sections of the slide groove 125 and the slider 212 cut by the surface perpendicular to the optical axis O are both irregular special shapes, which are closed "D" shapes surrounded by a straight line and an arc, wherein the arc corresponding to the inner wall of the slide groove 125 and the arc corresponding to the outer wall of the slider 212 have the same curvature, so that the slider 212 and the slide groove 125 can better match.

[0037] In the imaging device 100 of the embodiment of the present application, the slider 212 on the outer shell 21 cooperates with the slide groove 125 on the side panel 12 of the shell 10 to realize the movement of the lens group 22, so that the focal length of the imaging device 100 can be changed, and telephoto photography and wide-angle photography can be realized without setting a telephoto lens and a wide-angle lens at the same time.

[0038] See also Figure 3 and Figure 4 , the imaging device 100 according to the embodiment of the present application includes a housing 10 and a first lens module 20 .

[0039] The housing 10 includes a base plate 11 , side plates 12 , and a cover plate 13 . The base plate 11 , side plates 12 , and cover plate 13 form a receiving space 14 , and the first lens module 20 is disposed in the receiving space 14 .

[0040] The substrate 11 includes a supporting surface 111. The supporting surface 111 is used to support the side panel 12 and the first lens module 20. The substrate 11 can be a rectangular parallelepiped structure, a cube structure, a cylindrical structure, or other shapes, etc., without limitation. In this embodiment, the substrate 11 is a rectangular parallelepiped structure.

[0041] The side panels 12 are arranged around the edge of the base plate 11. The side panels 12 are perpendicular to the base plate 11. The side panels 12 can be arranged on the base plate 11 by gluing, screwing, snapping, etc. The side panels 12 can also be integrally formed with the base plate 11.

[0042] Please combine Figure 5 The side panel 12 includes an inner side surface 121, an outer side surface 122, an upper surface 123, and a lower surface 124. The inner side surface 121 faces away from the outer side surface 122. The inner side surface 121 is located within the receiving space 14, while the outer side surface 122 is located outside the receiving space 14. The inner side surface 121 is connected to both the upper surface 123 and the lower surface 124, while the outer side surface 122 is also connected to both the upper surface 123 and the lower surface 124. The upper surface 123 faces away from the lower surface 124. The lower surface 124 is coupled to the supporting surface 111 of the substrate 11, while the upper surface 123 faces away from the supporting surface 111 of the substrate 11.

[0043] The side panel 12 further includes a first side panel 127 and a second side panel 128 that are parallel to the optical axis O. The first side panel 127 and the second side panel 128 are opposite to each other. A sliding groove 125 and a mounting groove 126 are provided on the inner side surface 121 of the first side panel 127 and / or the inner side surface 121 of the second side panel 128. For example, the sliding groove 125 and the mounting groove 126 are provided on the inner side surface 121 of the first side panel 127, or the sliding groove 125 and the mounting groove 126 are provided on the inner side surface 121 of the second side panel 128, or the sliding groove 125 and the mounting groove 126 are provided on the inner side surface 121 of the first side panel 127 and the inner side surface 121 of the second side panel 128. In this embodiment, the sliding groove 125 and the mounting groove 126 are provided on the inner side surface 121 of the first side panel 127 and the inner side surface 121 of the second side panel 128, and the extending direction of the sliding groove 125 is parallel to the bearing surface 111.

[0044] The chute 125 communicates with the receiving space 14. The chute 125 extends parallel to the optical axis O. The depth of the chute 125 is less than the thickness of the side panel 12. In other embodiments, the chute 125 extends through the outer surface 122 of the side panel 12, allowing the receiving space 14 to communicate with the outside. The number of chute 125 defined on the inner surface 121 of the first side panel 127 and the inner surface 121 of the second side panel 128 can be one or more. For example, the inner side surface 121 of the first side panel 127 is provided with a slide groove 125, and the inner side surface 121 of the second side panel 128 is provided with a slide groove 125; for another example, the inner side surface 121 of the first side panel 127 is provided with two slide grooves 125, and the inner side surface 121 of the second side panel 128 is provided with two slide grooves 125; for another example, the inner side surface 121 of the first side panel 127 is provided with a slide groove 125, and the inner side surface 121 of the second side panel 128 is provided with two slide grooves 125, and so on, which are not listed one by one here. In this embodiment, the inner side surface 121 of the first side panel 127 and the inner side surface 121 of the second side panel 128 are both provided with a slide groove 125. The shape of the slide groove 125 cut by a plane perpendicular to the optical axis O is rectangular, semicircular, or other shapes, such as other regular shapes or irregular shapes. Please refer to Figure 7 In this embodiment, the shape of the slide groove 125 cut by a surface perpendicular to the optical axis O is an irregular special shape, which is a closed "D" shape surrounded by a straight line and an arc, wherein the shape of the inner wall of the slide groove 125 cut by the surface corresponds to the arc part of the "D" shape.

[0045] The mounting groove 126 is connected to the receiving space 14. One end of the mounting groove 126 extends through the upper surface 123 of the side panel 12, and the other end of the mounting groove 126 is connected to the slide groove 125. The extending direction of the mounting groove 126 can be perpendicular or inclined to the extending direction of the slide groove 125. For example, the extending direction of the mounting groove 126 is perpendicular to the optical axis O, or the extending direction of the mounting groove 126 is inclined at a certain angle to the optical axis O (not 0 degrees, but can be 30 degrees, 60 degrees, 120 degrees, etc.). In this embodiment, the extending direction of the mounting groove 126 is perpendicular to the optical axis O. The number of mounting grooves 126 defined on the inner surface 121 of the first side panel 127 and the inner surface 121 of the second side panel 128 can be one or more. For example, the inner side surface 121 of the first side panel 127 has one mounting groove 126, and the inner side surface 121 of the second side panel 128 has one mounting groove 126. For another example, the inner side surface 121 of the first side panel 127 has two mounting grooves 126, and the inner side surface 121 of the second side panel 128 has two mounting grooves 126. For another example, the inner side surface 121 of the first side panel 127 has one mounting groove 126, and the inner side surface 121 of the second side panel 128 has two mounting grooves 126, and so on. In this embodiment, both the inner side surface 121 of the first side panel 127 and the inner side surface 121 of the second side panel 128 have two mounting grooves 126.

[0046] The cover plate 13 is arranged on the side plate 12. Specifically, the cover plate 13 can be installed on the upper surface 123 of the side plate 12 by snapping, screwing, gluing, etc. The cover plate 13 includes a cover plate body 131 and a supporting portion 132. The cover plate body 131 is combined with the upper surface 123 of the side plate 12. The cover plate body 131 is provided with a light inlet 133, and the depth direction of the light inlet 133 can be perpendicular to the optical axis O, so that the imaging device 100 as a whole has a periscope structure. The supporting portion 132 is arranged on both sides of the cover plate body 131. Specifically, the supporting portion 132 is located on both sides of the cover plate 13 corresponding to the first side plate 127 and the second side plate 128 respectively. When the cover plate 13 is installed on the side plate 12, the supporting portion 132 is located in the mounting groove 126, and the supporting portion 132 is perpendicular to the bearing surface 111 of the substrate 11 (such as Figure 3As shown, the direction parallel to the optical axis O is defined as the x-direction, the direction perpendicular to the inner side surface 121 of the first side panel 127 is defined as the y-direction, the direction perpendicular to the bearing surface 111 is defined as the z-direction, and the length L of the x-direction, y-direction, and z-direction (the x-direction, the y-direction, and the z-direction are mutually perpendicular) is equal to the depth H of the mounting groove 126 along the z-direction. The abutting portion 132 being located in the mounting groove 126 can be: the abutting portion 132 being located in the mounting groove 126 and occupying part of the space of the mounting groove 126; or the abutting portion 132 being located in the mounting groove 126 can be: the abutting portion 132 being located in the mounting groove 126 and completely filling the mounting groove 126. In this embodiment, when the abutting portion 132 is installed in the mounting groove 126, the abutting portion 132 completely fills the mounting groove 126, and the abutting portion 132 is more firmly combined with the mounting groove 126, so that the connection between the cover plate 13 and the side panel 12 is more firmly established. In other embodiments, the light entrance 133 is not a through hole, but a light-transmitting solid structure, through which light can be incident into the receiving space 14 .

[0047] See also Figures 4 to 6 The first lens module 20 includes a housing 21 and a lens group 22. The lens group 22 is mounted on the housing 21. When the housing 21 slides, the housing 21 drives the lens group 22 to slide. The number of first lens modules 20 can be one or more, for example, the number of first lens modules 20 can be one, two, three, etc. In this embodiment, the number of first lens modules 20 is one.

[0048] The housing 21 includes a main body 211 and a slider 212. The slider 212 is fixedly connected to the main body 211.

[0049] The main body 211 includes a light inlet 2111 and a light outlet 2112 corresponding to the lens group 22. The main body 211 is formed with an accommodating space 2113 for accommodating the lens group 22. The accommodating space 2113 is connected to the accommodating space 14 through the light inlet 2111 and the light outlet 2112.

[0050] See also Figure 4 and Figure 5The slider 212 is movably mounted in the slide groove 125. The number of sliders 212 matches the number of corresponding mounting grooves 126. The matching of the number of sliders 212 and the number of corresponding mounting grooves 126 means that the number of sliders 212 located on the surface of the main body 211 opposite to the inner side surface 121 of the first side plate 127 is the same as the number of mounting grooves 126 opened on the inner side surface 121 of the first side plate 127, both of which are two; the number of sliders 212 located on the surface of the main body 211 opposite to the inner side surface 121 of the second side plate 128 is the same as the number of mounting grooves 126 opened on the inner side surface 121 of the second side plate 128, both of which are two, and the two sliders 212 correspond to the two mounting grooves 126 one-to-one. Of course, in other embodiments, the number of sliders 212 may be less than the number of mounting slots 126. For example, the number of sliders 212 located on the surface of the main body 211 opposite the inner side surface 121 of the first side panel 127 may be less than the number of mounting slots 126 defined on the inner side surface 121 of the first side panel 127, and the number of sliders 212 located on the surface of the main body 211 opposite the inner side surface 121 of the second side panel 128 may be less than the number of mounting slots 126 defined on the inner side surface 121 of the second side panel 128. Furthermore, the length d1 of the slider 212 along the x-direction is less than or equal to the length d2 of the mounting slot 126 along the x-direction, thereby facilitating the slider 212 to slide into the slide slot 125 after passing through the mounting slot 126.

[0051] The shape of the slider 212 cut by a surface perpendicular to the optical axis O can be rectangular, semicircular, or other shapes, such as other regular shapes or irregular shapes, as long as the shape of the slider 212 matches the shape of the corresponding slide groove 125. Specifically, the shape matching of the slider 212 and the corresponding slide groove 125 means that: when the cross-section of the slide groove 125 provided on the inner side surface 121 of the first side plate 127 cut by a surface perpendicular to the optical axis O is rectangular, then the cross-section of the slider 212 located on the surface of the main body 211 opposite to the inner side surface 121 of the first side plate 127 cut by a surface perpendicular to the optical axis O is also rectangular; when the cross-section of the slide groove 125 provided on the inner side surface 121 of the second side plate 128 cut by a surface perpendicular to the optical axis O is rectangular, then the cross-section of the slider 212 located on the surface of the main body 211 opposite to the inner side surface 121 of the second side plate 128 cut by a surface perpendicular to the optical axis O is The cross-section is also rectangular; when the cross-section of the slide groove 125 opened on the inner side surface 121 of the first side plate 127 is semicircular when cut by a surface perpendicular to the optical axis O, the cross-section of the slider 212 located on the surface of the main body 211 opposite to the inner side surface 121 of the first side plate 127 is also semicircular when cut by a surface perpendicular to the optical axis O; when the cross-section of the slide groove 125 opened on the inner side surface 121 of the second side plate 128 is semicircular when cut by a surface perpendicular to the optical axis O, the cross-section of the slider 212 located on the surface of the main body 211 opposite to the inner side surface 121 of the second side plate 128 is also semicircular when cut by a surface perpendicular to the optical axis O, and so on. They are not listed one by one here.

[0052] See also Figure 7 In this embodiment, the shape of the slider 212, as determined by a plane perpendicular to the optical axis O, is an irregular, non-uniform shape. This non-uniform shape is formed by a straight line and an arc to form a closed "D" shape. The shape of the slider 212's outer wall corresponds to the arc portion of the "D" shape. Matching the shape of the slider 212 with the corresponding shape of the chute 125 means that the arc corresponding to the inner wall of the chute 125 and the arc corresponding to the outer wall of the slider 212 have the same curvature. This ensures a better fit between the slider 212 and the chute 125.

[0053] In the z-direction, the opposite ends of the slider 212 abut against the opposite ends of the inner wall of the slide groove 125. Specifically, when the slider 212 is installed in the slide groove 125, in the z-direction, the opposite ends of the slider 212 corresponding to the first side plate 127 abut against the opposite ends of the inner wall of the slide groove 125 on the inner side surface 121 of the first side plate 127, and the opposite ends of the slider 212 corresponding to the second side plate 128 abut against the opposite ends of the inner wall of the slide groove 125 on the inner side surface 121 of the second side plate 128. As a result, the movement of the slider 212 in the z-direction is restricted, preventing the slider 212 from shaking or tilting along the z-direction, thereby ensuring that the imaging quality of the first lens module 20 is not affected.

[0054] The lens assembly 22 is disposed within the accommodating space 2113. Specifically, the lens assembly 22 can be mounted within the accommodating space 2113 by gluing, screwing, or snapping. The lens assembly 22 can be a single lens, either convex or concave; or it can include multiple lenses (e.g., two or three lenses), all of which can be convex or concave, or some can be convex and some can be concave. In this embodiment, the lens assembly 22 includes three lenses.

[0055] See also Figure 4 and Figure 6 The imaging device 100 further includes a second lens module 30 , a prism assembly 40 and a photosensitive element 50 .

[0056] The second lens module 30 includes a fixed housing 31 and a lens group 32. The lens group 32 is disposed in the fixed housing 31.

[0057] The fixed housing 31 is disposed on the supporting surface 111 of the substrate 11. Specifically, the fixed housing 31 can be fixedly mounted on the supporting surface 111 by gluing, screwing, or snapping. The fixed housing 31 can also be integrally formed with the substrate 11. The fixed housing 31 includes a light inlet 311, a light outlet 312, and a receiving cavity 313. The light inlet 311 and the light outlet 312 connect the receiving cavity 313 with the receiving space 14. The light outlet 312 is opposite the light inlet 2111 of the first lens module 20, and the light inlet 311 is opposite the lens assembly 32.

[0058] The lens assembly 32 is located within the receiving cavity 313 and can be mounted within the fixed housing 31 by gluing, screwing, or snapping. The lens assembly 32 can be a single lens, either convex or concave; or it can include multiple lenses (e.g., two or three lenses), all of which can be convex or concave, or some can be convex and some can be concave. In this embodiment, the lens assembly 32 includes two lenses.

[0059] The prism assembly 40 is disposed on the supporting surface 111 of the substrate 11 and is located in the receiving space 14 . The prism assembly 40 includes a mounting platform 41 and a prism 42 .

[0060] The mounting platform 41 is disposed on the supporting surface 111 of the substrate 11. Specifically, the mounting platform 41 can be mounted on the supporting surface 111 by gluing, screwing, snapping, or other methods. The mounting platform 41 can also be integrally formed with the substrate 11. The mounting platform 41 includes a light inlet hole 411, a light outlet hole 412, and a receiving cavity 413. The light inlet hole 411 and the light outlet hole 412 connect the receiving cavity 413 to the receiving space 14. The light inlet hole 411 is opposite to the light inlet port 133 of the cover plate 13, and the light outlet hole 412 is opposite to the light inlet hole 311 of the second lens module 30.

[0061] The prism 42 is disposed in the accommodating cavity 413 and can be mounted on the mounting platform 41 by gluing, snapping, or the like. The prism 42 includes an incident surface 421, a reflective surface 422, and an exit surface 423. The reflective surface 422 is obliquely connected to the incident surface 421 and the exit surface 423. The angle between the reflective surface 422 and the supporting surface 111 can be 15 degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees, or the like. In this embodiment, the angle between the reflective surface 422 and the supporting surface 111 is 45 degrees. The incident surface 421 is opposite to the light inlet hole 411, and the exit surface 423 is opposite to the light outlet hole 412. The prism 42 is used to change the exit direction of light entering from the light inlet hole 411. The prism 42 may be a triangular prism. Specifically, the cross section of the prism 42 is a right triangle, the two right-angled sides of the right triangle are respectively formed by the incident surface 421 and the exit surface 423 , and the hypotenuse of the right triangle is the reflection surface 422 .

[0062] The photosensitive element 50 is disposed on the inner side surface 121 of the side plate 12, and is opposite to the light outlet 2112 of the first lens module 20. The photosensitive element 50 can be a complementary metal oxide semiconductor (CMOS) photosensitive element 50 or a charge-coupled device (CCD) photosensitive element 50.

[0063] See also Figures 4 to 6 In this embodiment, the prism assembly 40, the second lens module 30 and the first lens module 20 are sequentially arranged in the receiving space 14 along the optical axis O. The prism assembly 40 and the second lens module 30 are fixedly arranged on the supporting surface 111 of the substrate 11; the slider 212 passes through the mounting groove 126 and slides into the slide groove 125, so that the slider 212 can be slidably arranged in the slide groove 125, thereby making the first lens module 20 slidably connected to the side panel 12. The slider 212 is fixedly connected to the main body 211. When the slider 212 slides in the slide groove 125, the relative distance between the first lens module 20 and the second lens module 30 changes. After the prism assembly 40, the second lens module 30 and the first lens module 20 are installed, the cover plate 13 is installed on the side panel 12, and the supporting portion 132 of the cover plate 13 is completely filled in the mounting groove 126. It can be understood that when the first lens module 20 slides, when the slider 212 passes through the position on the slide groove 125 corresponding to the installation groove 126, it may shake or tilt in the direction of the bearing surface 11 due to the lack of resistance from the inner wall of the slide groove 125. Therefore, after the supporting portion 132 completely fills the installation groove 126, the supporting portion 132 can resist the slider 212, thereby preventing the slider 212 from shaking or tilting in the z direction.

[0064] It should be noted that the electronic device 1000 may include a driving structure. For example, the driving structure may be a magnetic driving structure disposed in the receiving space 14. The magnetic driving structure includes a magnetic coil and a magnet. The magnetic coil may be disposed between the second lens module 30 and the first lens module 20, or between the prism assembly 40 and the second lens module 30, or between the first lens module 20 and the photosensitive element 50. The magnet may be disposed on the main body 211 of the first lens module 20. When electricity in different directions flows through the magnetic coil, corresponding magnetic fields are generated, thereby controlling the first lens module 20 equipped with the magnet to move away from or toward the magnetic coil, thereby causing the slider 212 to slide within the slide groove 125.

[0065] For another example, the drive structure can also be a linear motor. The stator of the linear motor can be fixedly mounted on the inner surface 121, and the mover of the linear motor extends from the stator and is connected to the main body 211. When the mover performs linear telescopic motion, it drives the main body 211 to move linearly, thereby causing the slider 212 to slide within the slide groove 125. There can be two linear motors, one disposed on the inner surface 121 of the first side plate 127, and one disposed on the inner surface 121 of the second side plate 128. The linear motor can be disposed on either side of the second lens module 30. For example, the linear motor can be located between the second lens module 30 and the first lens module 20, between the prism assembly 40 and the second lens module 30, or between the first lens module 20 and the photosensitive element 50. Of course, the drive structure can also be other structures, such as a hydraulic structure, a piezoelectric motor, etc., which are not listed here.

[0066] During imaging, light passes through the light inlet 133 of the cover plate 13 and the light inlet hole 411 of the prism assembly 40, is reflected by the reflective surface 422 of the prism 42, and is emitted from the light outlet hole 412. The light then passes through the light inlet 311, lens group 32, and light outlet 312 of the second lens module 30, and the light inlet 2111, lens group 22, and light outlet 2112 of the first lens module 20, ultimately reaching the photosensitive element 50 for imaging. The first lens module 20 can change its relative distance from the second lens module 30 by relative movement of the slider 212 within the slide groove 125, thereby changing the focal length of the imaging device 100 and achieving zooming of the imaging device 100.

[0067] See also Figure 4 and Figure 8 In some embodiments, the housing 21 further includes a top surface 213 and a bottom surface 214 opposite to each other. The top surface 213 is opposite to the cover plate 13. The bottom surface 214 is opposite to the bearing surface 111 of the substrate 11. The bottom surface 214 is provided with a first groove 215, and the surface of the substrate 11 opposite to the bottom surface 214 (i.e., the bearing surface 111) is formed with a first slide rail 112. The first lens module 20 further includes a first ball bearing 23, which is disposed in the first groove 215 and abuts against the bottom of the first slide rail 112.

[0068] Specifically, the first groove 215 matches the shape of the first ball 23. For example, the first ball 23 is spherical, with low resistance to movement. The first groove 215 is a semicircular groove, and the diameter of the first ball 23 is equal to the diameter of the first groove 215. In other words, half of the first ball 23 is located within the first groove 215. The first ball 23 and the first groove 215 are tightly coupled, and when the first ball 23 moves, it can drive the housing 21 of the first lens module 20 to move. The bearing surface 111 is formed with a first slide rail 112. The first slide rail 112 can be a groove formed on the bearing surface 111 and extending in a direction parallel to the optical axis O. The first slide rail 112 can also be a boss provided on the bearing surface 111 and extending in a direction parallel to the optical axis O. The surface of the boss opposite the bottom surface 214 of the housing 21 is formed with a groove that cooperates with the first ball 23. In this embodiment, the first slide rail 112 is a groove formed on the bearing surface 111, extending parallel to the optical axis O. After the first lens module 20 is installed in the receiving space 14, a portion of the first ball bearing 23 is located within the first slide rail 112 and abuts against the bottom of the first slide rail 112. The inner wall of the first slide rail 112, as cut by a plane perpendicular to the optical axis O, forms a first arc. The outer contour of the first ball bearing 23, as cut by a plane perpendicular to the optical axis O, forms a second arc, and the curvature of the first arc and the curvature of the second arc are the same. When the first ball bearing 23 rotates along the first slide rail 112, the outer walls of the first ball bearing 23, on opposite sides, abut against the inner walls of the first slide rail 112 in the y-direction. This restricts the movement of the first ball bearing 23 in the y-direction, thereby preventing the first lens module 20 from shaking or tilting in the y-direction.

[0069] The number of first grooves 215 can be one or more. For example, the number of first grooves 215 can be one, two, three, four, or even more. In this embodiment, the number of first grooves 215 is four. The number of first balls 23 can also be one or more. In this embodiment, the number of first balls 23 is the same as the number of first grooves 215, also four. The four first grooves 215 are spaced apart on the bottom surface 214 of the housing 21.

[0070] The number of first slide rails 112 can be one or more, and the number of first slide rails 112 is determined by the positions of the four first grooves 215. For example, if the centers of the four first grooves 215 are on a straight line parallel to the optical axis O, only one first slide rail 112 is required. For another example, if the four first grooves 215 are divided into two groups, each group includes two first grooves 215, the center line of the two first grooves 215 in each group is parallel to the optical axis O, and the center line of the two first grooves 215 in each group does not overlap, then two first slide rails 112 are required to correspond to the two first grooves 215 in each group. In this embodiment, the four first grooves 215 are divided into two groups, each group includes two first grooves 215, the center line of the two first grooves 215 in each group is parallel to each other and parallel to the optical axis O, and the four first grooves 215 can form a rectangle. In this way, when the four first balls 23 slide in the first slide rail 112, the four first balls 23 are confined in the two first slide rails 112, and because in the y direction, the opposite sides of the outer walls of the first balls 23 are abutted by the opposite sides of the inner walls of the first slide rail 112, the first lens module 20 can be prevented from shaking or tilting in the y direction, thereby ensuring that the imaging quality of the imaging device 100 is not affected.

[0071] See also Figure 4 and Figure 9 In some embodiments, a second groove 216 is formed on the top surface 213 of the housing 21 , and the first lens module 20 further includes a second ball 24 . The second ball 24 is disposed in the second groove 216 and contacts the cover 13 .

[0072] Specifically, the second groove 216 matches the shape of the second ball 24. For example, the second ball 24 is spherical and has low resistance to movement. The second groove 216 is a semicircular groove. The diameter of the second ball 24 is equal to the diameter of the second groove 216. In other words, half of the second ball 24 is located in the second groove 216. The second ball 24 and the second groove 216 are tightly coupled. When the second ball 24 moves, it can drive the housing 21 of the first lens module 20 to move. The number of second grooves 216 is one or more. For example, the number of second grooves 216 is one, two, three, four, or even more. In this embodiment, the number of second grooves 216 is four. The number of second balls 24 can also be one or more. In this embodiment, the number of second balls 24 is the same as the number of second grooves 216, which is also four. The four second grooves 216 are spaced apart on the top surface 213 of the housing 21. The second ball 24 is arranged in the second groove 216 and contacts the cover plate 13, so that the first lens module 20 is confined between the cover plate 13 and the substrate 11, which can prevent the first lens module 20 from shaking or tilting in the z direction, thereby ensuring that the imaging quality is not affected.

[0073] See also Figure 4 and Figure 10 In some embodiments, a second slide rail 134 is formed on a surface of the cover plate 13 opposite to the top surface 213 , and the second ball bearing 24 is disposed in the second groove 216 and abuts against the bottom of the second slide rail 134 .

[0074] Specifically, the second slide rail 134 can be a groove formed on the surface of the cover plate 13 opposite the top surface 213, extending parallel to the optical axis O. Alternatively, the second slide rail 134 can be a boss provided on the surface of the cover plate 13 opposite the top surface 213, extending parallel to the optical axis O. The boss' surface opposite the top surface 213 of the housing 21 is formed with a groove that engages with the second ball bearing 24. In this embodiment, the second slide rail 134 is a groove formed on the surface of the cover plate 13 opposite the top surface 213, extending parallel to the optical axis O. After the first lens module 20 is installed in the receiving space 14, a portion of the second ball bearing 24 is located within the second slide rail 134 and abuts against the bottom of the second slide rail 134. The inner wall of the second slide rail 134, as measured by a plane perpendicular to the optical axis O, forms a third arc shape. The outer contour of the second ball bearing 24, as measured by a plane perpendicular to the optical axis O, forms a fourth arc shape. The curvature of the third arc is the same as that of the fourth arc. When the second ball 24 rotates along the second slide rail 134, in the y direction, the opposite sides of the outer wall of the second ball 24 are abutted by the opposite sides of the inner wall of the second slide rail 134, so that the movement of the second ball 24 in the y direction is restricted, thereby further preventing the first lens module 20 from shaking or tilting in the y direction.

[0075] The number of second slide rails 134 can be one or more, and the number of second slide rails 134 is determined by the positions of the four second grooves 216. For example, if the centers of the four second grooves 216 are on a straight line parallel to the optical axis O, only one second slide rail 134 is required. For another example, if the four second grooves 216 are divided into two groups, each group includes two second grooves 216, and the center line connecting the two second grooves 216 in each group is parallel to the optical axis O, and the center line connecting the two second grooves 216 in each group does not overlap, then two second slide rails 134 are required to correspond to the two second grooves 216 in each group. In this embodiment, the four second grooves 216 are divided into two groups, each group includes two second grooves 216, and the center line connecting the two second grooves 216 in each group is parallel to each other and parallel to the optical axis O. The four second grooves 216 can form a rectangle. In this way, when the four second balls 24 slide in the second slide rails 134, the four second balls 24 are restricted in the two second slide rails 134, and because in the y direction, the opposite sides of the outer walls of the second balls 24 are abutted by the opposite sides of the inner walls of the second slide rails 134, the first lens module 20 can be prevented from shaking or tilting in the y direction, thereby further ensuring that the imaging quality of the imaging device 100 is not affected.

[0076] See also Figure 11 In some embodiments, the number of first lens modules 20 can be multiple, and the sliders 212 of multiple first lens modules 20 can be movably installed in the slide groove 125. The housing 10 also includes a spacer 15, which is connected to the side panel 12. Two adjacent first lens modules 20 are separated by a spacer 15.

[0077] Specifically, two adjacent first lens modules 20 are separated by a spacer 15, and the spacer 15 can limit the first lens module 20. The moving stroke of each first lens module 20 can be determined according to the focal length range of the imaging device 100, and then the installation position of the spacer 15 can be determined according to the moving stroke of each first lens module 20. As long as the spacer 15 does not block the light outlet 2112 and the spacer 15 can accurately limit the first lens module 20, it can be done. Figure 11 As shown, there are two first lens modules 20. A spacer plate 15 is provided between the two first lens modules 20, so that one of the two first lens modules 20 can only move between the spacer plate 15 and the second lens module 30, and the other of the two first lens modules 20 can only move between the spacer plate 15 and the photosensitive element 50.
