[0054] The present disclosure does not make specific limitation on the material of the shell 1, which can be matched and set according to the use scene, manufacturing cost and other factors of the camera module, for example, metal, plastic, glass and the like.

[0055] The present disclosure does not make specific limitation on the processing mode of the shell 1, which can be matched and set according to the material of the shell 1 and other factors, for example, when the shell 1 is made of metal material, the shell 1 can be obtained by using an integrated casting process, or by using a process such as threaded fastening connection or welding after block processing; when the shell 1 is made of plastic material, the shell 1 can be obtained by using an integrated injection molding process, or by using a connection method such as glue dispensing.

[0056] 2. The prism 2

[0057] The prism 2 is located in the opening 11 of the housing 1. The prism 2 is used to change the propagation direction of external light. The light in the external environment can pass through the prism 2 at the opening 11 and be transmitted to the lens assembly 5 and the image sensor 6 in sequence.

[0058] The present disclosure does not specifically limit the shape and size of the prism 2, and can be matched and set according to factors such as the angle at which the prism 2 needs to change the light propagation. The embodiment of the present disclosure takes the prism 2 as a right triangle as an example, and other similar situations will not be repeated.

[0059] The prism 2 is connected to the shell 1. The present disclosure does not specifically limit the connection relationship between the prism 2 and the shell 1. Removable connection methods such as threaded fastening connection and snap connection can be adopted, or non-detachable connection methods such as glue dispensing and welding can be adopted. The specific setting can be matched according to factors such as the usage scenario of the camera module and the connection strength of different camera modules between the prism 2 and the shell 1.

[0060] 3. First drive component 3

[0061] The first drive assembly 3 is connected to the housing 1 and the second drive assembly 4 respectively. The first drive assembly 3 is used to drive the second drive assembly 4 to move along a first direction, wherein the first direction is the direction of light propagation from the prism 2 to the lens assembly 5, or the first direction is the opposite direction of the light propagation direction from the prism 2 to the lens assembly 5.

[0062] Reference Figure 2 As shown, Figure 2 3 is a partial schematic diagram of a camera module provided by an embodiment of the present disclosure. The first driving component 3 may include a circuit board 31, a first coil 32, a first magnetic member 34 and a first support frame 33.

[0063] 3.1. Circuit board 31

[0064] The circuit board 31 is connected to the housing 1. The present disclosure does not specifically limit the connection relationship between the circuit board 31 and the housing 1. Removable connection methods such as threaded fastening and snap connection can be used, and non-removable connection methods such as glue dispensing and welding can also be used. The specific setting can be matched according to factors such as the use scenario of the camera module and the materials of the circuit board 31 and the housing 1.

[0065] The present disclosure does not specifically limit the material and quantity of the circuit board 31. For example, the present disclosure takes a flexible printed circuit 31 (FPC) as an example. Two flexible printed circuit boards 31 are respectively connected to the two opposite inner walls of the shell 1 and electrically connected to the first coil 32 to enable the first coil 32 to be energized.

[0066] 3.2. The first coil 32 and the first magnetic member 34

[0067] In some embodiments, the first coil 32 can be connected to the housing 1 and electrically connected to the circuit board 31, and the first magnetic member 34 is opposite to the first coil 32 and connected to the outer wall of the first support frame 33. When the first coil 32 is powered, according to the principle of electromagnetic induction, the current passes through the first coil 32, and a corresponding magnetic field can be formed around the first coil 32. The magnetic field generated by the first coil 32 interacts with the first magnetic member 34, and the magnetic force generated causes the first magnetic member 34 to have a tendency to move relative to the first coil 32, and then the first magnetic member 34 drives the first support frame 33 to slide relative to the first coil 32.

[0068] The embodiments of the present disclosure take the first coil 32 connected to the housing 1 and the first magnetic member 34 connected to the outer wall of the first support frame 33 as an example for illustration, and other cases are similar and will not be repeated here.

[0069] The number and shape of the first magnetic member 34 are not specifically limited by the present disclosure. When the number of the first magnetic member 34 is one, the first magnetic member 34 can be connected to one side of the outer wall of the first support frame 33. When the number of the first magnetic member 34 is more than one, the first magnetic member 34 can be connected to at least two sides of the outer wall of the first support frame 33. The shape of the first magnetic member 34 can be rectangular, trapezoidal, circular, triangular, etc.

[0070] The relative area of the first magnetic member 34 and the first coil 32 is not specifically limited by the present disclosure, and can be matched and set according to the movement distance requirement of the camera module on the first driving assembly 3.

[0071] The connection form of the first magnetic member 34 and the outer wall of the first support frame 33 is not specifically limited by the present disclosure. The first magnetic member 34 can be attached to the surface of the outer wall of the first support frame 33, or the outer wall of the first support frame 33 can have a corresponding accommodating groove, and at least part of the first magnetic member 34 is located in the accommodating groove.

[0072] In some other embodiments, the first magnetic member 34 can be connected to the housing 1. The first coil 32 is connected to the outer wall of the first support frame 33 and electrically connected to the circuit board 31, and the first magnetic member 34 is opposite to the first coil 32. When the first coil 32 is powered, according to the principle of electromagnetic induction, the current passes through the first coil 32, and a corresponding magnetic field can be formed around the first coil 32. The magnetic field generated by the first coil 32 interacts with the first magnetic member 34, and the magnetic force generated causes the first coil 32 to have a tendency to move relative to the first magnetic member 34, and then the first coil 32 drives the first support frame 33 to slide relative to the first magnetic member 34.

[0073] 3.3. The first support frame 33

[0074] The interior of the first support frame 33 has a cavity for accommodating the second driving assembly 4 and the lens assembly 5. The magnetic field generated by the first coil 32 interacts with the first magnetic member 34, and the magnetic force generated causes the first magnetic member 34 to drive the first support frame 33 to slide relative to the first coil 32. During the sliding of the first support frame 33 relative to the first coil 32, the lens assembly 5 can move towards or away from the image sensor 6. Since the distance between the lens assembly 5 and the image sensor 6 is variable, the distance between the focusing object of the camera module and the camera module can be changed, thereby realizing the zoom function of the camera module.

[0075] 3.4. The first elastic sheet 35 and the second elastic sheet 36

[0076] Referring to Figure 4 , Figure 4 is another structural schematic diagram of a camera module provided by the embodiment of the present disclosure. The first driving assembly 3 can further include a first elastic sheet 35, and the first elastic sheet 35 is connected to the side wall of the housing 1 and the side wall of the first support frame 33 facing the prism 2, respectively.

[0077] The shape of the first elastic sheet 35 is not limited in the present disclosure, for example, a mouth-shaped, a sun-shaped, a U-shaped, a strip-shaped, and the like. The embodiment of the present disclosure takes the first elastic sheet 35 as a mouth-shaped for example, and other cases are similar and will not be described herein.

[0078] The pair of opposite frames of the mouth-shaped first elastic sheet 35 are fixedly connected to the side wall of the housing 1 and the side wall of the first support frame 33 facing the prism 2, respectively. The other pair of opposite frames of the first elastic sheet 35 have the ability of elastic deformation, and can elastically deform within a certain range and return to a natural state.

[0079] When the camera module is in the initial state, the first elastic sheet 35 is in the natural state. The first coil 32 is energized, the first magnetic member 34 and the first support frame 33 move relative to the first coil 32, and gradually approach the prism 2. The frame with the ability of elastic deformation of the first elastic sheet 35 deforms. When the first support frame 33 moves to the maximum distance relative to the first coil 32, the frame is still within the elastic deformation range. The first coil 32 stops energizing. Under the action of the elastic force of the frame, the first support frame 33 gradually moves away from the prism 2 until the camera module returns to the initial state, and the first elastic sheet 35 also returns to the natural state, thereby realizing the reset of the first support frame 33.

[0080] Referring to Figure 5 , Figure 5 is another structural schematic diagram of a camera module provided by the embodiment of the present disclosure. The first driving assembly 3 can further include a second elastic sheet 36, and the second elastic sheet 36 is connected to the side wall of the housing 1 and the side wall of the first support frame 33 facing the image sensor 6, respectively.

[0081] The present disclosure does not specifically limit the shape of the second elastic piece 36, for example, a U-shape, a Japanese-style shape, a U-shape, a strip, etc. The embodiment of the present disclosure takes the U-shape of the second elastic piece 36 as an example for description, and other similar situations are not repeated here.

[0082] A pair of opposite frames of the second U-shaped spring piece 36 are fixedly connected to the side wall of the shell 1 and the first support frame 33 facing the image sensor 6 respectively. Another pair of opposite frames of the second spring piece 36 has the ability of elastic deformation, and can undergo elastic deformation within a certain range and return to a natural state.

[0083] During the relative movement of the first support frame 33 relative to the first coil 32 , the second elastic piece 36 may also undergo corresponding elastic deformation. The working principle is similar to that of the first elastic piece 35 and will not be repeated here.

[0084] The first spring piece 35 and the second spring piece 36 work together to clamp the first support frame 33, thereby achieving suspension between the first support frame 33 and the first coil 32. The first support frame 33 and the first coil 32 do not have direct contact, which can reduce the friction between the first support frame 33 and the first coil 32, and avoid the relative sliding between the first support frame 33 and the first coil 32 causing wear on the corresponding area of ​​the first support frame 33 or the first coil 32, which is beneficial to increase the service life of the camera module and improve the user experience of the terminal device.

[0085] 4. Second drive assembly 4

[0086] The second driving assembly 4 is connected to the lens assembly 5, and the second driving assembly 4 is used to drive the lens assembly 5 to move along a first direction, wherein the first direction is the direction of light propagation from the prism 2 to the lens assembly 5, or the first direction is the opposite direction of the light propagation direction from the prism 2 to the lens assembly 5.

[0087] Reference Figure 3 As shown, Figure 3 It is a partial cross-sectional view of a camera module provided by an embodiment of the present disclosure. The second driving assembly 4 may include a second magnetic member 41 , a second coil 42 and a second support frame 43 .

[0088] 4.1. Second Magnetic Component 41 and Second Coil 42

[0089] In some embodiments, the second magnetic member 41 can be connected to the inner wall of the first support frame 33; the second coil 42 is opposite to the second magnetic member 41 and is connected to the second support frame 43. When the second coil 42 is powered, according to the principle of electromagnetic induction, the current passes through the second coil 42, and a corresponding magnetic field can be formed around the second coil 42. The magnetic field generated by the second coil 42 interacts with the second magnetic member 41, and the magnetic force generated makes the second coil 42 have a tendency to move relative to the second magnetic member 41, and then the second coil 42 drives the second support frame 43 to slide relative to the second magnetic member 41 and the first support frame 33.

[0090] The embodiments of the present disclosure take the second magnetic member 41 connected to the inner wall of the first support frame 33 and the second coil 42 connected to the second support frame 43 as an example for description, and other cases are similar and will not be repeated here.

[0091] The number and shape of the second magnetic member 41 are not limited in the present disclosure. When the number of the second magnetic member 41 is one, the second magnetic member 41 can be connected to one side of the inner wall of the first support frame 33. When the number of the second magnetic member 41 is more than one, the second magnetic member 41 can be connected to at least two sides of the inner wall of the first support frame 33. The shape of the second magnetic member 41 can be rectangular, trapezoidal, circular, triangular, etc.

[0092] The relative area of the second magnetic member 41 and the second coil 42 is not limited in the present disclosure, and can be matched and set according to the movement distance requirement of the camera module to the second driving assembly 4.

[0093] The connection form of the second magnetic member 41 and the inner wall of the first support frame 33 is not limited in the present disclosure. The second magnetic member 41 can be attached to the surface of the inner wall of the first support frame 33, or the inner wall of the first support frame 33 has a corresponding accommodating groove, and at least part of the first magnetic member 34 is located in the accommodating groove.

[0094] In some other embodiments, the second magnetic member 41 can be connected to the second support frame 43. The second coil 42 is connected to the inner wall of the first support frame 33, and the second magnetic member 41 is opposite to the second coil 42. When the second coil 42 is powered, according to the principle of electromagnetic induction, the current passes through the second coil 42, and a corresponding magnetic field can be formed around the second coil 42. The magnetic field generated by the second coil 42 interacts with the second magnetic member 41, and the magnetic force generated makes the second magnetic member 41 have a tendency to move relative to the second coil 42, and then the second magnetic member 41 drives the second support frame 43 to slide relative to the second magnetic member 41 and the first support frame 33.

[0095] In the embodiments of the present disclosure, the second coil 42 can be connected to the power supply module of the terminal device through a wire on the circuit board 31, or can be electrically connected through one or more of the first elastic sheet 35, the second elastic sheet 36, the third elastic sheet 44, and the fourth elastic sheet 45. For example, the first elastic sheet 35 and the third elastic sheet 44 are made of conductive materials (for example, metal, conductive ceramics, etc.), and the first elastic sheet 35 and the third elastic sheet 44 are front elastic sheets formed by an integrated casting process. One end of the front elastic sheet is connected to the shell 1 and is electrically connected to the wire embedded in the shell 1. The other end of the front elastic sheet is electrically connected to the second coil 42 through related elements (for example, a wire, etc.). Such a design can reduce the amount of wire used to connect the second coil 42 to other elements, reduce the manufacturing cost of the camera module, and avoid the wire being squeezed or pulled during the movement of the first driving mechanism and the second driving mechanism, thereby causing the second coil 42 to be in poor contact or fail, and reducing the service life of the camera module.

[0096] 4.2. Second support frame 43

[0097] The second support frame 43 has a cavity inside, and the cavity of the second support frame 43 is used to accommodate the lens assembly 5. The magnetic field generated by the second coil 42 interacts with the second magnetic member 41, and the magnetic force generated causes the second coil 42 to drive the second support frame 43 to slide relative to the second magnetic member 41 and the first support frame 33. During the sliding process of the second support frame 43 relative to the first support frame 33, the lens assembly 5 can move towards or away from the image sensor 6. Since the distance between the lens assembly 5 and the image sensor 6 is variable, the distance between the object in focus of the camera module and the camera module can be changed, thereby realizing the zoom function of the camera module.

[0098] 4.3. Third elastic sheet 44 and fourth elastic sheet 45

[0099] Referring to Figure 4 As shown in FIG. 4, the second driving assembly 4 can further include a third elastic sheet 44, which is connected to the side wall of the first support frame 33 facing the prism 2 and the side wall of the second support frame 43 facing the prism 2.

[0100] The present disclosure does not make specific limitations on the shape of the third elastic sheet 44, for example, a mouth-shaped, a sun-shaped, a U-shaped, a strip-shaped, etc. The embodiments of the present disclosure take the third elastic sheet 44 as a strip-shaped structure as an example for description, and other cases are similar and will not be described here.

[0101] One end of the third elastic sheet 44 in a strip-shaped structure is fixedly connected to the side wall of the first support frame 33 facing the prism 2, and the other end is fixedly connected to the side wall of the second support frame 43 facing the prism 2. The region between the two ends of the third elastic sheet 44 in a strip-shaped structure has the ability of elastic deformation and can elastically deform within a certain range and recover to a natural state.

[0102] When the camera module is in the initial state, the third elastic sheet 44 is in the natural state, the second coil 42 is powered on, the second coil 42 and the second support frame 43 move relative to the second magnetic member 41 and the first support frame 33 to gradually approach the prism 2, the region of the third elastic sheet 44 having the elastic deformation capability deforms, when the second support frame 43 moves to the maximum distance relative to the first coil 32, the elastic region is still within the elastic deformation range thereof, the second coil 42 stops being powered on, under the action of the elastic force of the elastic region, the second support frame 43 gradually moves away from the prism 2 until the camera module returns to the initial state, and the third elastic sheet 44 also returns to the natural state, thereby achieving the reset of the second support frame 43.

[0103] In some embodiments, referring to Figure 8 , the second support frame 43 is provided with a third elastic sheet 44, and the third elastic sheet 44 is connected to the side wall of the second support frame 43 facing the prism 2. Figure 8 is another structural schematic diagram of a camera module provided by the embodiments of the present disclosure, the end of the third elastic sheet 44 fixedly connected to the side wall of the second support frame 43 facing the prism 2 has a large area, and when the camera module is in the initial state, the end can abut against the side wall of the first support frame 33 facing the prism 2, which is beneficial to the limiting effect on the second support frame 43. Specifically, after the second coil 42 stops being powered on, when the second support frame 43 returns to the initial relative position thereof and the first support frame 33 from the current position thereof, the second support frame 43 can be prevented from crossing the initial relative position thereof due to inertia and other factors, and thus approaching the image sensor 6 to cause impact on the image sensor 6 and other adverse phenomena.

[0104] Referring to Figure 5 , the second driving assembly 4 can further include a fourth elastic sheet 45, and the fourth elastic sheet 45 is connected to the side wall of the first support frame 33 facing the image sensor 6 and the side wall of the second support frame 43 facing the image sensor 6.

[0105] The shape of the fourth elastic sheet 45 is not limited in the present disclosure, for example, a mouth-shaped structure, a sun-shaped structure, a U-shaped structure, a strip-shaped structure, and the like. The embodiments of the present disclosure take the strip-shaped structure of the fourth elastic sheet 45 as an example for description, and other cases are similar and will not be described herein.

[0106] One end of the strip-shaped fourth elastic sheet 45 is fixedly connected to the side wall of the first support frame 33 facing the image sensor 6, and the other end is fixedly connected to the side wall of the second support frame 43 facing the image sensor 6. The region between the two ends of the strip-shaped fourth elastic sheet 45 has the capability of elastic deformation, and can elastically deform within a certain range and return to the natural state.

[0107] In the process of the relative movement of the second support frame 43 relative to the first support frame 33, the fourth elastic sheet 45 can also elastically deform correspondingly, and the principle is similar to the working process of the third elastic sheet 44, which will not be described herein.

[0108] The third elastic sheet 44 and the fourth elastic sheet 45 jointly realize the clamping effect on the second support frame 43, thereby realizing the suspension between the second support frame 43 and the first support frame 33, and the second support frame 43 and the first support frame 33 do not have direct contact, which can reduce the friction between the second support frame 43 and the first support frame 33, avoid the relative sliding between the second support frame 43 and the first support frame 33 from causing abrasion on the corresponding area of the outer wall of the second support frame 43 or the inner wall of the first support frame 33, and is beneficial to increasing the service life of the camera module and improving the user experience of the terminal device.

[0109] 5. Lens assembly 5

[0110] The lens assembly 5 can include a lens shell and a plurality of lenses, the plurality of lenses are fixed relative to each other, the focal length of the lens assembly 5 is fixed, the plurality of lenses are connected to the inner wall of the lens shell, and the outer wall of the lens shell is connected to the second driving assembly 4.

[0111] The number of lenses is not specifically limited in the disclosure, and can be matched and set according to the requirements of different camera modules on the focal length parameters of the lens assembly 5. The shape and size of the lens shell are not specifically limited in the disclosure, and can be matched and set according to factors such as the shape, size and relative distance of the plurality of lenses.

[0112] In the embodiment of the disclosure, the lens assembly 5 is located between the prism 2 and the image sensor 6, the light entrance side of the lens assembly 5 faces the prism 2, and the light exit side of the lens assembly 5 faces the image sensor 6. Since the shell 1 has an opening 11, which can serve as a light entrance port of the camera module, the prism 2 is located in the opening 11, and the light entrance surface of the prism 2 faces the external environment, the light exit surface of the prism 2 faces the light entrance surface of the lens assembly 5, and the light exit surface of the lens assembly 5 faces the light sensing surface of the image sensor 6. In this way, external light can enter the camera module through the opening 11 of the shell 1, the prism 2 can refract the light incident to the prism 2 by a preset angle, and the refracted light is sequentially transmitted to the lens assembly 5 and the image sensor 6, thereby realizing the light sensing process of the camera module.

[0113] 6. Image sensor 6

[0114] The image sensor 6 (COMS Image Sensor, CIS) is located at the light exit side of the lens assembly 5, and is used to receive the optical signal passing through the lens assembly 5 and convert the optical signal into an electrical signal.

[0115] The image sensor 6 is connected to the housing 1. The present disclosure does not specifically limit the connection relationship between the image sensor 6 and the housing 1. Removable connection methods such as threaded fastening and snap connection can be used, and non-removable connection methods such as glue dispensing and welding can also be used. The specific setting can be matched according to factors such as the usage scenario of the camera module and the connection strength of different camera modules between the image sensor 6 and the housing 1.

[0116] The working process of the camera module is as follows:

[0117] First, the camera module is in the initial state, refer to Figure 6 As shown, Figure 6 This is an exploded schematic diagram of a camera module provided by an embodiment of the present disclosure. The first side wall 33a of the first support frame 33 and the second side wall 43a of the second support frame 43 perpendicular to the first direction are flush with each other. At this time, the first spring piece 35 respectively connected to the shell 1 and the first side wall 33a is in a natural state, and the third spring piece 44 respectively connected to the first side wall 33a and the second side wall 43a is also in a natural state.

[0118] Based on the same principle, the third side wall opposite to the first side wall 33a and the fourth side wall opposite to the second side wall 43a are also flush with each other. At this time, the second spring piece 36 connected to the shell 1 and the third side wall respectively is in a natural state, and the fourth spring piece 45 connected to the third side wall and the fourth side wall respectively is also in a natural state.

[0119] When the second coil 42 is energized, a corresponding magnetic field is formed around the second coil 42. The magnetic field generated by the second coil 42 interacts with the second magnetic part 41, and the generated magnetic force makes the second coil 42 tend to move relative to the second magnetic part 41. Then, the second coil 42 drives the second support frame 43 to slide relative to the second magnetic part 41 and the first support frame 33. At this time, the lens assembly 5 connected to the second support frame 43 realizes the first movement.

[0120] When the first coil 32 is energized, a corresponding magnetic field is formed around the first coil 32. The magnetic field generated by the first coil 32 interacts with the first magnetic part 34, and the generated magnetic force makes the first magnetic part 34 tend to move relative to the first coil 32. Then, the first magnetic part 34 drives the first support frame 33 to slide relative to the first coil 32. At this time, the first support frame 33 drives the second support frame 43 and the lens assembly 5 to move, and the lens assembly 5 realizes the second movement.

[0121] Then, the first coil 32 and the second coil 42 are de-energized. The first support frame 33, under the elastic force of the first and second springs 35 and 36, moves to its original relative position with respect to the housing 1. The second support frame 43, under the elastic force of the third and fourth springs 44 and 45, moves to its original relative position with respect to the first support frame 33. Ultimately, the first side wall 33a of the first support frame 33 and the second side wall 43a of the second support frame 43, which are perpendicular to the first direction, return to a mutually flush position. The camera module returns to its initial state and awaits the next operating instruction.

[0122] The present disclosure does not impose any specific limitation on the order in which the first coil 32 and the second coil 42 are energized, and the order can be matched and set according to factors such as the usage scenario of the camera module.
