Abstract
Description
Technical Field
[0001] This invention relates to the field of optical imaging, and more specifically to a base for a periscope camera module, a reflective module, and a method for manufacturing the base. Background Technology
[0002] Camera modules are an essential component of mobile electronic devices. With the further development of camera module technology, user demands for them are becoming increasingly sophisticated. The development of camera products not only needs to meet high-performance requirements such as background blur, night shooting, and dual-camera zoom, but also needs to meet the requirements of miniaturization, portability, and compactness. In particular, periscope camera modules, through their reflective and lens modules, achieve a longer focal length by using a folded optical path, thus simultaneously meeting the demands for high zoom and a slim design, and have broad market prospects.
[0003] Periscope camera modules typically use a voice coil motor to drive a reflective element to deflect around its rotation axis to correct image shift caused by camera shake. However, as users' requirements for image quality and image stabilization performance continue to increase, higher standards are being placed on the control precision and response speed of the reflective module. Therefore, there is an urgent need for a new reflective module structure that can simultaneously improve sensing accuracy and connection reliability. Summary of the Invention

[0056] The present invention will now be further described in conjunction with specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0057] In the description of this invention, it should be noted that directional terms such as "center," "lateral," "longitudinal," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this invention.
[0058] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0059] It is understandable that the reflection module in a periscope camera module typically employs a position-sensing magnet and a position-sensing element to form a closed-loop control system to improve control accuracy. One of the position-sensing magnet and the position-sensing element is fixed to a rotatable carrier, while the other is fixed to a base or other fixed component, with the magnet and element positioned opposite each other. When the carrier rotates, the relative position of the magnet and element changes. The position-sensing element can determine the position of the carrier by sensing the strength of the magnetic field from the magnet, and then adjust the drive current to rotate the carrier to the desired position, thus forming a closed-loop control. The inventors discovered that in related technologies, due to spatial constraints of the reflection module, a large distance between the position-sensing element and the magnet leads to attenuation of the magnetic field signal acquired by the element and a decrease in detection sensitivity, thus limiting the control accuracy and response speed of the reflection module.
[0060] To address or at least partially alleviate the aforementioned shortcomings, this application provides a base 1 for a periscope camera module, such as... Figures 1-7As shown, the system includes a base 10 and a plurality of conductive elements 20. The base 10 includes a base bottom wall 12 and a base side wall 13. The base side wall 13 is connected to the periphery of the base bottom wall 12, and the base bottom wall 12 and the base side wall 13 form a receiving space 11. Specifically, the base side wall 13 includes a first base side wall 131 and a second base side wall 132 disposed opposite to each other along a third axis, a third base side wall 133 connecting the first base side wall 131 and the second base side wall 132, and a fourth base side wall 134 disposed opposite to the third base side wall 133 along a second axis. The receiving space 11 is formed between the first base side wall 131, the second base side wall 132, the third base side wall 133, the fourth base side wall 134 and the base bottom wall 12.
[0061] Furthermore, such as Figure 3 As shown, each conductive element 20 is embedded within the base 10, and each conductive element 20 includes a first conductive branch 21 embedded in the side wall 13 of the base. Specifically, the first conductive branch 21 is embedded in either the first base side wall 131 or the second base side wall 132. The first conductive branch 21 is bent at a first position 211 and a second position 212, with the first position 211 being closer to the center of the receiving space 11 than the second position 212 in the third axial direction. The third axial direction is parallel to the width direction of the base 1.
[0062] It should be understood that in this application, the position sensing magnet is disposed on the movable carrier 50 within the accommodating space 11, and the position sensing magnet and the position sensing element 73 are disposed opposite each other along the third axis direction. Further, as... Figure 6 As shown, compared to the second position 212, the first conductive branch 21 is closer to the center of the receiving space 11 at the first position 211. The portion of the first conductive branch 21 at the first position 211 is used for electrical connection with the position sensing element 73. That is, the position sensing element 73 is welded to the portion of the first conductive branch 21 at the first position 211, thereby being able to get closer to the position sensing magnet in the receiving space 11. This allows the position sensing element 73 to obtain a stronger magnetic field signal in a more compact space, thereby compensating for the possible decrease in sensing linearity or attenuation of the magnetic field signal due to the increase in rotation angle. This is beneficial for maintaining high-precision position sensing throughout the entire rotation stroke of the movable carrier 50.
[0063] Furthermore, such as Figure 4 and Figure 5As shown, the base 10 includes a first molding portion 141, which is formed at a first position 211 and a second position 212. The first molding portion 141 has a first groove 1413. The first conductive branch 21 is exposed in the first groove 1413 at the first position 211, and the first conductive branch 21 is covered by the first molding portion 141 at the second position 212. Specifically, the first molding portion 141 is part of the base sidewall 13. Through the first injection molding, the first molding portion 141 can pre-fix the first conductive branch 21 at the first position 211 and the second position 212, which helps to avoid the first conductive branch 21 from twisting, deforming or shifting in subsequent processes, thereby improving the positional accuracy of the first conductive branch 21 in the base sidewall 13.
[0064] In this configuration, the first conductive branch 21 is covered by the first molding portion 141 at the second position 212, meaning that both sides of the first conductive branch 21 at the second position 212 are covered by the first molding portion 141, thereby improving the connection strength and reliability between the first conductive branch 21 and the first molding portion 141. One side surface of the first conductive branch 21 at the first position 211 is exposed within the first groove 1413, allowing it to connect with the position sensing element 73 through the exposed surface.
[0065] In some embodiments, such as Figures 3-5 As shown, the base 1 of the periscope camera module also includes a position sensing element 73, which is disposed within the first groove 1413 and electrically connected to the exposed portion of the first conductive branch 21 at the first position 211. It should be understood that the position sensing element 73 being disposed within the first groove 1413 protects it from damage by the first molding portion 141. It also allows the position of the position sensing element 73 to be closer to the position sensing magnet located on the movable carrier 50.
[0066] It is worth mentioning that, such as Figure 3 , Figure 4 and Figure 6As shown, at least a portion of the first conductive branch 21 at the first position 211 is exposed on the bottom surface of the first groove 1413. In other words, by opening the first groove 1413 on the first forming part 141, it is possible to help locate the area on the first conductive branch 21 that is used to weld with the position sensing element 73, and to help locate the installation position of the position sensing element 73 on the base 10, thereby reducing the positioning difficulty when welding the position sensing element 73 in the future. It is also possible to make the installation position of the position sensing element 73 on each base 10 more uniform. In other words, it is possible to improve the consistency of each base 1, thereby making the subsequent assembly of the reflection module and camera module smoother and improving the product yield.
[0067] Furthermore, the first molding part 141 has good molding accuracy and positional accuracy because it is formed by the first injection molding. The bottom surface of the first groove 1413 can also provide a relatively flat mounting surface for the position sensing element 73, so that the plane where the position sensing element 73 is located is perpendicular to the third axis direction, thereby improving the sensing accuracy.
[0068] In some embodiments, such as Figure 3 , Figure 4 and Figure 6 As shown, the plane containing the first position 211 along the second axis is parallel to the plane containing the second position 212 along the second axis. In other words, both the plane containing the first position 211 and the plane containing the second position 212 are perpendicular to the third axis. This allows the overall extension direction of the first conductive element 20 to be parallel to the first base sidewall 131 and the second base sidewall 132. Consequently, when the first conductive branch 21 is embedded in the first base sidewall 131 or the second base sidewall 132, it helps to avoid the first conductive element 20 occupying too much space within the base sidewall 13, allowing the base sidewall 13 to maintain a smaller wall thickness. Furthermore, it helps to prevent the first conductive branch 21 from extending obliquely relative to the base sidewall 13, thus avoiding local thinning of the base sidewall 13 and improving the structural strength of the base sidewall 13. The second axis is parallel to the length direction of the base 1, and the third axis is perpendicular to the second axis.
[0069] Furthermore, such as Figure 3As shown, the first conductive branch 21 is bent at least once from the first position 211 to the second position 212. In at least one embodiment, the first conductive branch 21 is bent once from the first position 211 to the second position 212, and the portion of the first conductive branch 21 located between the first position 211 and the second position 212 extends along or approximately along the third axis direction; in other words, the bending angle is 90° or approximately 90°, thereby improving the deformation resistance of the first conductive branch 21; and enabling the number of bends of the first conductive branch 21 to be relatively small, thereby simplifying the bending process of the first conductive branch 21; and also enabling the length of the first conductive branch 21 to be reduced, thereby reducing the resistance.
[0070] In other embodiments, the first conductive branch 21 undergoes two or more stepped bends from the first position 211 to the second position 212, thereby dispersing the stress on the first conductive branch 21 more effectively and improving its fatigue resistance. Furthermore, the bend angles of the first conductive branch 21 can also be obtuse angles to further reduce the stress on the first conductive branch 21; this application does not impose specific limitations on this.
[0071] In some embodiments, such as Figure 6 As shown, the distance between the first conductive branch 21 at the first position 211 and the outer surface of the base sidewall 13 is greater than the distance between the first conductive branch 21 at the second position 212 and the outer surface of the base sidewall 13. It should be understood that the portion of the first conductive branch 21 located at the first position 211 is closer to the center of the receiving space 11 than the portion of the first conductive branch 21 located at the second position 212; therefore, the portion of the first conductive branch 21 located at the second position 212 is closer to the outer surface of the base sidewall 13 than the portion of the first conductive branch 21 located at the first position 211.
[0072] In at least one instance, such as Figure 6As shown, the first base sidewall 131 includes a first base portion 1311 and a second base portion 1312 arranged along a second axis. The first base portion 1311 is disposed opposite to the movable carrier 50 of the reflective module along a third axis. The outer surface of the first base portion 1311 is coplanar with the outer surface of the second base portion 1312, and the inner surface of the first base portion 1311 is closer to the center of the receiving space 11 than the inner surface of the second base portion 1312. Furthermore, the portion of the first conductive branch 21 located at the first position 211 is embedded in the first base portion 1311, so as to be disposed opposite to the movable carrier 50 along the third axis. The portion of the first conductive branch 21 located at the second position 212 is embedded in the second base portion 1312, and the portion of the first conductive branch 21 located at the second position 212 is closer to the outer surface of the first base sidewall 131 than the portion of the first conductive branch 21 located at the first position 211. Furthermore, the first groove 1413 is located in the first base portion 1311, and the position sensing element 73 is welded to the first conductive branch 21 and exposed on the surface of the first groove 1413 at the first position 211, so that the position sensing element 73 is closer to the center of the receiving space 11 in the third axial direction than the inner side of the second base portion 1312.
[0073] This should be understandable, such as Figure 6 As shown, by providing a first base portion 1311 protruding towards the center of the receiving space 11 and a first conductive branch 21 recessing towards the receiving space 11 at a first position 211, the position sensing element 73 can be recessed towards the center of the receiving space 11 without increasing the external dimensions of the base 10. This not only helps to miniaturize the periscope camera module but also allows the position sensing element 73 to be closer to the position sensing magnet on the movable carrier 50, thereby increasing the magnetic field signal strength acquired by the position sensing element 73. In other words, the average intensity of the magnetic field signal acquired by the position sensing element 73 can be improved throughout the entire rotation stroke of the movable carrier 50, thus achieving higher precision position sensing. Especially when the rotation angle of the reflector module is large, for example, exceeding ±5°, by making the position sensing element 73 recessed towards the center of the receiving space 11, the position sensing element 73 can acquire a stronger magnetic field signal in a more compact space, thereby compensating for the possible decrease in sensing linearity or attenuation of the magnetic field signal due to the increased rotation angle.
[0074] In some embodiments, such as Figure 3 , Figure 4 and Figure 7As shown, the first conductive branch 21 is also bent at the third position 213. In the third axial direction, the third position 213 is further away from the center of the receiving space 11 than the second position 212. The first conductive branch 21 is exposed on the outer side of the base sidewall 13 at the third position 213, so as to be in communication with the circuit board 40 fixed on the outer side of the base sidewall 13. The circuit board 40 is used to electrically connect with the photosensitive circuit board 201 of the photosensitive module 200, so that the position sensing element 73 is in communication with the photosensitive circuit board 201 through the conductive member 20 and the circuit board 40. In addition, the electrically connected circuit board 40 can also be used to install the drive coil of the reflection module and be electrically connected to the drive coil.
[0075] It is understandable that since the circuit board 40 is fixed to the outer side of the base sidewall 13, if the position sensing element 73 is mounted on the circuit board 40, the position sensing element 73 will be far away from the position sensing magnet on the movable carrier 50. If the circuit board 40 is bent so that a part of the circuit board 40 is located at the first position 211, and the position sensing element 73 is placed on the part of the circuit board 40 located at the first position 211, the distance between the position sensing element 73 and the position sensing magnet can be reduced. However, the circuit board 40 is bent repeatedly and densely, which will greatly increase the risk of the circuit board 40 breaking, thus reducing the production yield of the base 1.
[0076] In this embodiment, the first conductive branch 21 can be flexibly bent. By bending the first conductive branch 21 to a first position 211 and welding the position sensing element 73 to the portion of the first conductive branch 21 at the first position 211, the distance between the position sensing element 73 and the position sensing magnet can be reduced. Furthermore, the drive coil is disposed on the circuit board 40, which helps to avoid adding conductive parts 20 to conduct the drive coil, thereby reducing the number of conductive parts 20 embedded in the base 10, reducing the manufacturing difficulty of the base 1, and reducing the manufacturing cost of the base 1. Furthermore, by bending the first conductive branch 21 to the third position 213 and connecting the circuit board 40 with the portion of the first conductive branch 21 located at the third position 213, it is beneficial to achieve close connection between the conductive component 20 and the circuit board 40. In other words, it can shorten the extension length of the first conductive branch 21 in the base sidewall 13, thereby further reducing the manufacturing difficulty and cost of the base 1; it can also simplify the wiring in the circuit board 40, thereby reducing the complexity and manufacturing cost of the circuit board 40.
[0077] In some embodiments, such as Figure 4 and Figure 5As shown, the first molding portion 141 is also formed at the third position 213, which allows for pre-fixation of the portion of the first conductive branch 21 at the third position 213. Furthermore, one side surface of the first conductive branch 21 at the third position 213 is exposed through the first molding portion 141, thereby enabling it to connect and conduct with the circuit board 40 through the exposed surface.
[0078] In some embodiments, such as Figure 3 and Figure 7 As shown, the plane containing the third position 213 along the second axis is parallel to the plane containing the second position 212 along the second axis, and also parallel to the plane containing the first position 211 along the second direction. In other words, the plane containing the third position 213 and the plane containing the second position 212 are both perpendicular to the third axis. This makes the structure of the first conductive element 20 more compact, which helps to avoid the first conductive element 20 occupying too much space in the base sidewall 13, and allows the base sidewall 13 to maintain a small wall thickness and good structural strength.
[0079] Furthermore, such as Figure 3 As shown, the first conductive branch 21 is bent at least once from the second position 212 to the third position 213. In at least one embodiment, the first conductive branch 21 is bent once from the second position 212 to the third position 213, and the portion of the first conductive branch 21 located between the second position 212 and the third position 213 extends along or approximately along the third axis direction, thereby improving the deformation resistance of the first conductive branch 21, simplifying the bending process of the first conductive branch 21, and reducing the length of the first conductive branch 21 to reduce resistance. In other embodiments, the first conductive branch 21 is bent two or more times from the second position 212 to the third position 213, thereby dispersing the stress on the first conductive branch 21 more and improving the fatigue resistance of the first conductive branch 21. This application does not impose specific limitations on this.
[0080] In some embodiments, the first conductive branch 21 is bent once from the first position 211 to the third position 213, and the portion of the first conductive branch 21 located between the first position 211 and the third position 213 extends along or approximately along the third axis direction, thereby improving the deformation resistance of the first conductive branch 21, simplifying the bending process of the first conductive branch 21, and reducing the length of the first conductive branch 21 to reduce resistance.
[0081] In other embodiments, such as Figure 3As shown, the first conductive branch 21 bends once from the first position 211 to the second position 212, and then bends once from the second position 212 to the third position 213, thereby dispersing the stress on the first conductive branch 21 more effectively and improving the fatigue resistance of the first conductive branch 21.
[0082] In some embodiments, such as Figure 7 As shown, the distance between the first conductive branch 21 at the second position 212 and the outer surface of the base sidewall 13 is greater than the distance between the first conductive branch 21 at the third position 213 and the outer surface of the base sidewall 13. It should be understood that the portion of the first conductive branch 21 located at the second position 212 is closer to the center of the receiving space 11 than the portion of the first conductive branch 21 located at the third position 213; therefore, the portion of the first conductive branch 21 located at the third position 213 is closer to the outer surface of the base sidewall 13 than the portion of the first conductive branch 21 located at the second position 212.
[0083] In at least one embodiment, such as Figure 7 As shown above, the first base sidewall 131 includes a first base portion 1311 and a second base portion 1312 arranged along the second axis. The first base portion 1311 and the movable carrier 50 of the reflective module are arranged opposite each other along the third axis. The outer surface of the first base portion 1311 and the outer surface of the second base portion 1312 are coplanar. Furthermore, the portions of the first conductive branch 21 located at the second position 212 and the third position 213 are both embedded in the second base portion 1312. The portion of the first conductive branch 21 located at the third position 213 is closer to the outer surface of the first base sidewall 131 than the portion located at the second position 212. This is so that one side surface of the first conductive branch 21 located at the third position 213 is flush with or protrudes from the outer surface of the first base sidewall 131, allowing one side surface of the first conductive branch 21 located at the third position 213 to be exposed on the outer surface of the first base sidewall 131, thereby enabling electrical connection between the portion of the first conductive branch 21 located at the third position 213 and the circuit board 40. It is worth mentioning that the portion of the first conductive branch 21 located at the third position 213 can also be embedded in the first base portion 1311; this application does not impose specific limitations on this.
[0084] In some embodiments, such as Figures 3-7As shown, the first conductive branch 21 is embedded in the side wall 131 of the first base. Each conductive component 20 also includes a second conductive branch 22 embedded in the side wall 132 of the second base. The second conductive branch 22 is electrically connected to the first conductive branch 21. The second conductive branch 22 and the first conductive branch 21 are arranged opposite to each other along the third axis. The second conductive branch 22 is bent at the fourth position 221 and the fifth position 222. In the third axis direction, the fourth position 221 is closer to the center of the receiving space 11 than the fifth position 222.
[0085] This should be understandable, such as Figure 3 , Figure 6 and Figure 7 As shown, compared to the fifth position 222, the second conductive branch 22 is closer to the center of the receiving space 11 at the fourth position 221. The portion of the second conductive branch 22 at the fourth position 221 is used for electrical connection with the position sensing element 73. That is, the position sensing element 73 is welded to the portion of the second conductive branch 22 at the fourth position 221, thereby being able to get closer to the position sensing magnet in the receiving space 11. This allows the position sensing element 73 to obtain a stronger magnetic field signal in a more compact space, thereby compensating for the possible decrease in sensing linearity or attenuation of magnetic field signal due to the increase in rotation angle. This is beneficial for maintaining high-precision position sensing throughout the entire rotation stroke of the movable carrier 50.
[0086] In some embodiments, such as Figure 3 , Figure 6 and Figure 7 As shown, the plane containing the fourth position 221 along the second axis is parallel to the plane containing the fifth position 222 along the second axis. In other words, both the plane containing the fourth position 221 and the plane containing the fifth position 222 are perpendicular to the third axis. This allows the overall extension direction of the second conductive element 20 to be parallel to the second base sidewall 132, which helps to avoid the second conductive element 20 occupying too much space in the second base sidewall 132 and allows the second base sidewall 132 to maintain a small wall thickness. In addition, it also helps to avoid the second base sidewall 132 from being too thin locally, thereby improving the structural strength of the second base sidewall 132.
[0087] Furthermore, such as Figure 3As shown, the second conductive branch 22 undergoes at least one bend from the fourth position 221 to the fifth position 222. In at least one embodiment, the second conductive branch 22 undergoes one bend from the fourth position 221 to the fifth position 222, and the portion of the second conductive branch 22 located between the fourth position 221 and the fifth position 222 extends along or approximately along the third axis direction, thereby improving the deformation resistance of the second conductive branch 22, simplifying the bending process of the second conductive branch 22, and reducing the length of the second conductive branch 22 to reduce resistance. In other embodiments, the second conductive branch 22 undergoes two or more stepped bends from the fourth position 221 to the fifth position 222, thereby dispersing the stress on the second conductive branch 22 more effectively and improving the fatigue resistance of the second conductive branch 22. This application does not impose specific limitations on this aspect.
[0088] In some embodiments, such as Figure 4 and Figure 5 As shown, the base 10 also includes a second molding portion 142, which is formed at the fourth position 221 and the fifth position 222, and covers at least a portion of the second conductive branch 22. The second molding portion 142 has a second groove 1423. The second conductive branch 22 is exposed in the second groove 1423 at the fourth position 221, and the second conductive branch 22 is covered by the second molding portion 142 at the fifth position 222.
[0089] Specifically, the second molding part 142 is part of the second base sidewall 132, and the second molding part 142 is formed by the first injection molding. In other words, the first molding part 141 and the second molding part 142 together form the first injection molding part 14, and are formed simultaneously in the first injection molding. It should be understood that the second molding part 142 can pre-fix the portions of the second conductive branch 22 at the fourth position 221 and the fifth position 222, which helps to avoid the second conductive branch 22 from twisting, deforming or shifting in subsequent processes, thereby improving the positional accuracy of the second conductive branch 22 in the base sidewall 13.
[0090] In this configuration, the second conductive branch 22 is covered by the second molding portion 142 at the fifth position 222, meaning that both sides of the second conductive branch 22 at the fifth position 222 are covered by the second molding portion 142, thereby improving the connection strength and reliability between the second conductive branch 22 and the second molding portion 142. At the fourth position 221, one side of the second conductive branch 22 is exposed within the second groove 1423, allowing it to connect with the position sensing element 73 through the exposed surface.
[0091] In some embodiments, such as Figure 3 and Figure 5As shown, the position sensing element 73 is disposed within the second groove 1423, and the position sensing element 73 is electrically connected to the exposed portion of the second conductive branch 22 located at the fourth position 221. It should be understood that the placement of the position sensing element 73 within the second groove 1423 also provides protection for the position sensing element 73 through the second molding portion 142, helping to prevent damage to the position sensing element 73. Furthermore, it allows the position of the position sensing element 73 to be closer to the position sensing magnet located on the movable carrier 50.
[0092] It is worth noting that in this embodiment, the base 1 of the periscope camera module has two position sensing elements 73. One position sensing element 73 is disposed in the first groove 1413 and electrically connected to the first conductive branch 21; the other position sensing element 73 is disposed in the second groove 1423 and electrically connected to the second conductive branch 22. In this way, by combining the magnetic field change signals acquired by the two position sensing elements 73, it is beneficial to prevent the rotational motion of the moving carrier 50 in other directions from interfering with the sensing results. The rotational motion in other directions refers to the rotational motion of the non-moving carrier 50 about its own rotation axis. In one example, the two position sensing elements 73 can be implemented to sense the rotation of the moving carrier 50 about the second axis.
[0093] In some embodiments, such as Figure 3 As shown, the first position 211 and the fourth position 221 are opposite each other along the third axis, and the second position 212 and the fifth position 222 are opposite each other along the third axis; the distance between the first position 211 and the fourth position 221 is less than the distance between the second position 212 and the fifth position 222. Furthermore, the portion of the first conductive branch 21 at the first position 211 and the portion of the second conductive branch 22 at the fourth position 221 are symmetrically arranged with the second axis A2 of the base 1 as the center line, and the portion of the first conductive branch 21 at the second position 212 and the portion of the second conductive branch 22 at the fifth position 222 are symmetrically arranged with the second axis A2 of the base 1 as the center line. It should be understood that a position sensing element 73 is welded to the portion of the first conductive branch 21 located at the first position 211, and another position sensing element 73 is welded to the portion of the second conductive branch 22 located at the fourth position 221. The arrangement of the first conductive branch 21 and the second conductive branch 22 in the above manner is beneficial to make the two position sensing elements 73 symmetrically arranged with the second axis A2 of the base 1 as the center line. In other words, the line connecting the two position sensing elements 73 is perpendicular to the second axis A2 of the base 1. This is beneficial to ensure that the magnetic field signals detected by the two position sensing elements 73 of the moving carrier 50 rotating in other directions are opposite, so that they can cancel each other out to improve the position sensing accuracy.
[0094] Furthermore, along the third axis, the first conductive branch 21 is closer to the second conductive branch 22 at the first position 211 and the second conductive branch 22 is closer to the fourth position 221, so that both position sensing elements 73 are closer to the center of the housing space 11, that is, closer to the position sensing magnet in the housing space 11, and can obtain a stronger magnetic field signal in a more compact space.
[0095] In some embodiments, the second conductive branch 22 is also bent at a sixth position, which is further away from the center of the receiving space 11 than the fifth position 222 in the third axial direction. The second conductive branch 22 is exposed on the outer side of the second base sidewall 132 at the sixth position, so as to be in communication with the circuit board 40 fixed on the outer side of the second base sidewall 132.
[0096] In other words, as mentioned above, the first conductive branch 21 can be bent to the third position 213, and the exposed portion of the first conductive branch 21 at the third position 213 can be connected to the circuit board 40 fixed to the outer side of the sidewall 131 of the first base; or, the second conductive branch 22 can be bent to the sixth position, and the exposed portion of the second conductive branch 22 at the sixth position can be connected to the circuit board 40 fixed to the outer side of the sidewall 132 of the second base. This application does not impose specific limitations on this. That is to say, in this application, only one of the first conductive branch 21 and the second conductive branch 22 needs to be electrically connected to the circuit board 40, which simplifies the conduction method between the conductive component 20 and the circuit board 40.
[0097] In some embodiments, the second molding portion 142 is also formed at the sixth position to pre-fix the portion of the second conductive branch 22 at the sixth position. Furthermore, one side surface of the second conductive branch 22 at the sixth position is exposed through the second molding portion 142, thereby enabling it to connect and conduct with the circuit board 40 through the exposed surface.
[0098] In at least one instance, such as Figure 6 and Figure 7As shown, the second base sidewall 132 includes a third base portion 1321 and a fourth base portion 1322 arranged along the second axis. The third base portion 1321 is disposed opposite to the movable carrier 50 of the reflective module along the third axis. The outer surface of the third base portion 1321 is coplanar with the outer surface of the fourth base portion 1322, and the inner surface of the third base portion 1321 is closer to the center of the receiving space 11 than the inner surface of the fourth base portion 1322. Furthermore, the portion of the second conductive branch 22 located at the fourth position 221 is embedded in the third base portion 1321 to be disposed opposite to the movable carrier 50 along the third axis, and the portion of the second conductive branch 22 located at the fifth position 222 is embedded in the fourth base portion 1322. The portion of the second conductive branch 22 located at the fifth position 222 is closer to the outer surface of the second base sidewall 1322 than the portion of the second conductive branch 22 located at the fourth position 221. Furthermore, the second groove 1423 is located in the third base portion 1321, and the position sensing element 73 is welded to the second conductive branch 22 at the fourth position 221 exposed on the surface of the second groove 1423, such that the position sensing element 73 is closer to the center of the receiving space 11 in the third axial direction than the inner side of the fourth base portion 1322.
[0099] It should be understood that by providing a third base portion 1321 protruding towards the center of the receiving space 11, and by having the second conductive branch 22 recessed towards the receiving space 11 at a fourth position 221, the position sensing element 73 can be recessed towards the center of the receiving space 11 without increasing the external dimensions of the base 10. This not only helps to miniaturize the periscope camera module, but also allows the position sensing element 73 to be closer to the position sensing magnet on the movable carrier 50. Consequently, the average intensity of the magnetic field signal acquired by the position sensing element 73 can be improved throughout the entire rotation stroke of the movable carrier 50, thereby achieving higher precision position sensing.
[0100] In at least one embodiment, the portion of the second conductive branch 22 located at the sixth position is embedded in the fourth base portion 1322, and the portion of the second conductive branch 22 located at the sixth position is closer to the outer surface of the second base sidewall 132 than the portion of the second conductive branch 22 located at the fifth position 222, so that one side surface of the second conductive branch 22 located at the sixth position is flush with or protrudes from the outer surface of the second base sidewall 132. It is worth mentioning that the portion of the second conductive branch 22 located at the sixth position can also be embedded in the third base portion 1321, and this application does not specifically limit this.
[0101] In some embodiments, such as Figure 3As shown, each conductive component 20 also includes a third conductive branch 23, which is embedded in the bottom wall 12 or the side wall 13 of the base. The third conductive branch 23 connects between the first conductive branch 21 and the second conductive branch 22 and is electrically connected to the first conductive branch 21 and the second conductive branch 22. The first conductive branch 21, the second conductive branch 22, and the third conductive branch 23 are distributed on opposite sides, which helps to avoid the distribution of each conductive branch being too concentrated, thereby making the structural strength of each base side wall 13 and base bottom wall 12 more uniform.
[0102] It should be understood that each position sensing element 73 has at least four pins, therefore each position sensing element 73 needs to be soldered to at least four conductive elements 20 to function properly. If the first conductive branch 21 and the second conductive branch 22 are set independently and not connected, then eight conductive elements 20 are required to support the normal operation of the two position sensing elements 73. Furthermore, circuit boards 40 need to be set on the first base sidewall 131 and the second base sidewall 132 respectively to be connected to the first conductive branch 21 and the second conductive branch 22. This not only increases the number of conductive elements 20 and makes the structure more complex, but also increases the size of the base sidewall 13 to embed more conductive elements 20.
[0103] In this embodiment, such as Figure 3 As shown, by connecting and electrically connecting the first conductive branch 21 and the second conductive branch 22 via the third wire branch, the two position sensing elements 73 can share four conductive elements 20. Furthermore, the circuit board 40 can be disposed only on one of the first base sidewall 131 and the second base sidewall 132. In other words, the positions on the four conductive elements 20 that are connected to the circuit board 40 are located on the same sidewall of the base 10, thereby simplifying the circuit connection of the base 1 and improving the soldering efficiency of the circuit board 40 and the conductive elements 20.
[0104] It is worth mentioning that the four conductive elements 20 can also be connected to the circuit board 40 at different sidewalls of the base 10. For example, two conductive elements 20 can be connected to the circuit board 40 at the first base sidewall 131, and the other two conductive elements 20 can be connected to the circuit board 40 at the second base sidewall 132. This application does not impose any specific restrictions on this.
[0105] In at least one embodiment, each conductive element 20 further includes a first element connection region 24 and a second element connection region 25 for communication with the position sensing element 73, and a line connection region 26 for communication with the circuit board 40. The first element connection region 24 is located at the end of the first conductive branch 21 and at a first position 211, exposed within the first groove 1413, and is capable of communication with one of the position sensing elements 73. The second element connection region 25 is located at the end of the second conductive branch 22 and at a fourth position 221, exposed within the second groove 1423, and is capable of communication with the other position sensing element 73. The line connection region 26 is located at the end or middle of the conductive element 20 and at a third position 213, exposed on the outer surface of the first base sidewall 131, and is capable of communication with the circuit board 40.
[0106] In some embodiments, such as Figure 4 and Figure 5 As shown, the base 10 also includes a third molding part 143, which covers at least a portion of the third conductive branch 23, thereby pre-fixing the third conductive branch 23. This helps to prevent the third conductive branch 23 from twisting, deforming, or shifting in subsequent processes, thus improving the positional accuracy of the third conductive branch 23 in the base 10. It is worth noting that the third molding part 143 is formed by the first injection molding. In other words, the first molding part 141, the second molding part 142, and the third molding part 143 together constitute the first injection molding part 14 and are formed simultaneously in the first injection molding, thereby simplifying the molding process of the base 10 and saving manufacturing and time costs.
[0107] In at least one embodiment, the third conductive branch 23 is embedded in the bottom wall 12 of the base, and the third molded portion 143 is part of the bottom wall 12 of the base. In at least one other embodiment, the third conductive branch 23 is embedded in the third base side wall 133, and the third molded portion 143 is part of the third base side wall 133. This application does not impose specific limitations on this.
[0108] In some embodiments, the first molding portion 141 is located on the side wall 131 of the first base. After the first conductive branch 21 is bent at the first position 211 and the second position 212, the first molding portion 141 is integrally injection molded with at least a portion of the first conductive branch 21. The second molding portion 142 is located on the side wall 132 of the second base. After the second conductive branch 22 is bent at the fourth position 221 and the fifth position 222, the second molding portion 142 is integrally injection molded with at least a portion of the second conductive branch 22.
[0109] Specifically, as mentioned above, such as Figure 4As shown, the portion of the first conductive branch 21 at the first position 211 and at least a portion of the first conductive branch 21 at the second position 212 are covered by the first molding portion 141, and the first molding portion 141 has a first groove 1413. One side surface of the first conductive branch 21 at the first position 211 is exposed in the first groove 1413. When the first conductive branch 21 is bent and located at the third position 213, the portion of the first conductive branch 21 at the third position 213 is also covered by the first molding portion 141, and one side surface of the first conductive branch 21 at the third position 213 is exposed in the first molding portion 141. The first molding portion 141 constitutes a part of the first base sidewall 131.
[0110] Similarly, such as Figure 4 As shown, a portion of the second conductive branch 22 at the fourth position 221 and at least a portion of the second conductive branch 22 at the fifth position 222 are covered by the second molding portion 142, and a second groove 1423 is formed on the second molding portion 142. One side surface of the second conductive branch 22 at the fourth position 221 is exposed in the second groove 1423. When the second conductive branch 22 is bent and located at the sixth position, a portion of the second conductive branch 22 at the sixth position is also covered by the second molding portion 142, and one side surface of the second conductive branch 22 at the sixth position is exposed in the second molding portion 142. The second molding portion 142 constitutes a part of the second base sidewall 132.
[0111] It is worth mentioning that the first molding part 141, the second molding part 142, and the aforementioned third molding part 143 are all formed by a first injection molding. Further, a second injection molding part 15 is formed by a second injection molding. The second injection molding part 15 covers at least a portion of the conductive element 20 and covers the outer periphery of the first molding part 141, the second molding part 142, and the third molding part 143, thereby forming a complete base bottom wall 12 and base side wall 13.
[0112] In some embodiments, the position sensing element 73 includes, but is not limited to: TMR (Tunnel Magnetoresistance) sensor, HES (Hall Effect Sensor), and Hall IC (Hall Effect Integrated Circuit).
[0113] A reflection module, such as Figures 1-17As shown, the system includes: a base 10, several conductive components 20, a circuit board 40, a movable carrier 50, a rotation drive magnet 71, a position sensing element 73, and a rotation drive coil 72. The base 10 includes a base bottom wall 12 and a base side wall 13, with the side wall 13 connected to the periphery of the base bottom wall 12. The base bottom wall 12 and the base side wall 13 form a receiving space 11. Specifically, the base side wall 13 includes a first base side wall 131 and a second base side wall 132 arranged opposite each other along a third axis, and a third base side wall 133 connecting the first base side wall 131 and the second base side wall 132. The receiving space 11 is formed between the first base side wall 131, the second base side wall 132, the third base side wall 133, and the base bottom wall 12. The movable carrier 50 is movably disposed within the receiving space 11 of the base 10, and the movable carrier 50 is used to carry the reflective element 300 and drive the reflective element 300 to rotate. The reflective element 300 is used to reflect light incident along a first axis to a second axis. The first axis is parallel to the height direction of the reflective module, and the second axis is parallel to the length direction of the reflective module.
[0114] Furthermore, such as Figure 7 and Figure 10 As shown, a rotary drive magnet 71 is disposed on the movable carrier 50. Each conductive element 20 is embedded within the base 10; a position sensing element 73 is disposed on the base 10 and electrically connected to the conductive elements 20. The position sensing element 73 is positioned opposite to the rotary drive magnet 71, thereby enabling the position sensing element 73 to acquire the magnetic field signal of the rotary drive magnet 71 to sense the rotational stroke of the movable carrier 50, thus achieving closed-loop control of the reflection module. Furthermore, a circuit board 40 is disposed on the outer surface of the base 10, with at least a portion of each conductive element 20 exposed on the outer surface of the base sidewall 13 for electrical connection to the circuit board 40. A rotary drive coil 72 is disposed on and electrically connected to the circuit board 40, and the rotary drive coil 72 and the rotary drive magnet 71 cooperate to drive the movable carrier 50 to rotate relative to the base 10.
[0115] In other words, the position sensing element 73 is indirectly connected to the circuit board 40 through the conductive element 20 embedded in the base 10, while the rotary drive coil 72 is mounted on the circuit board 40 and directly connected to it. This avoids the need to add additional conductive elements 20 to connect the rotary drive coil 72, thereby reducing the number of conductive elements 20 embedded in the base 10 and lowering the manufacturing difficulty and cost of the base 10. It also avoids the need to bend the circuit board 40 to connect the position sensing element 73, reducing the risk of circuit board 40 breakage. Moreover, connecting the position sensing element 73 solely through the conductive element 20 allows for a reasonable arrangement of the number and structure of the conductive elements 20, satisfying the requirement for the position sensing element 73 to be close to the rotary drive magnet 71 while simplifying the connection of the position sensing element 73. Furthermore, the processes of soldering the position sensing element 73 to the conductive element 20 and installing the rotary drive coil 72 on the circuit board 40 can be performed independently on two separate production lines, further improving the production efficiency of the reflection module and the periscope camera module.
[0116] It is worth mentioning that the rotary drive magnet 71 can cooperate with the rotary drive coil 72 and provide a magnetic field for the position sensing element 73. This helps to avoid the need to add an additional position sensing magnet to cooperate with the position sensing element 73, thereby reducing the load on the moving carrier 50. The moving carrier 50 can be driven to rotate with a smaller driving force, and the angle adjustment can be achieved more quickly and accurately, which can improve the control accuracy and response speed of the reflection module.
[0117] In some embodiments, such as Figure 9 and Figure 10 As shown, the reflection module also includes a middle frame 60, a pitch support 82, and a rotation support 81. Specifically, the middle frame 60 is rotatably disposed within the receiving space 11 about a third axis A3. The middle frame 60 supports the movable carrier 50 along a first axis, allowing the movable carrier 50 to rotate relative to the middle frame 60 about a first axis A1 or a second axis A2. The pitch support 82 is disposed between the middle frame 60 and the base 10 to support the rotation of the middle frame 60 relative to the base 10 about a third axis A3. The rotation support 81 is disposed between the movable carrier 50 and the middle frame 60 to support the rotation of the movable carrier 50 relative to the middle frame 60 about a first axis A1 or a second axis A2. In this way, the reflection element 300 can rotate about two mutually perpendicular directions to provide more comprehensive jitter compensation. The first axis A1, the second axis A2, and the third axis A3 are mutually perpendicular.
[0118] In at least one embodiment, the movable carrier 50 carries the reflective element 300 to rotate around the second axis A2, causing the image on the imaging surface of the photosensitive module 200 to rotate around the second axis A2. This compensates for rotational and tilt jitter during use of the periscope camera module, reducing phase aberration and improving image quality. It should be understood that the rotational movement of the reflective element 300 around the second axis A2 compensates for the rotational direction. Since the imaging surface is located in the plane containing the first and third axes, the image plane projected onto the imaging surface after the reflective element 300 rotates around the second axis A2 does not affect the image size. Consequently, the MTF axis value of the reflective element 300 during its rotation around the second axis A2 is consistent with the MTF axis value at infinity (INF state). In other words, the rotational movement of the reflective element 300 around the second axis A2 only involves rotation of the image plane angle, without any shift in the image plane height position, and therefore does not affect the MTF axis value. Among them, MTF (Modulation Transfer Function) is a visual representation that provides a precise and quantitative evaluation of the resolution capability of a periscope camera module.
[0119] In some embodiments, such as Figure 11 As shown, the movable carrier 50 includes an integrally formed carrier body 51, a first carrier side portion 521, and a second carrier side portion 522. Specifically, the carrier body 51 has an inclined mounting surface 511, which is used to fix the reflective element 300 so that the movable carrier 50 can support and drive the reflective element 300 to rotate together. The first carrier side portion 521 and the second carrier side portion 522 are located opposite each other along a third direction on both sides of the carrier body 51, so that a mounting cavity 512 is formed between the first carrier side portion 521, the second carrier side portion 522, and the mounting surface 511. The mounting cavity 512 is used to accommodate the reflective element 300.
[0120] Furthermore, such as Figure 12 As shown, the movable carrier 50 also includes a carrier bottom 54 connected to the carrier body 51. The carrier bottom 54 extends from the carrier body 51 along a first axis toward the base bottom wall 12. A rotary drive magnet 71 is disposed on the side surface of the carrier bottom 54 facing the base bottom wall 12. The circuit board 40 includes a first plate 41 disposed on the outer side of the base bottom wall 12. A rotary drive coil 72 is disposed on the first plate 41 and electrically connected to the first plate 41, so that the rotary drive coil 72 and the rotary drive magnet 71 are arranged opposite to each other along the first axis.
[0121] Specifically, such as Figure 10 and Figure 12As shown, the rotary drive magnet 71 includes a first rotary drive magnet 711 and a second rotary drive magnet 712 spaced apart along the third axis. The rotary drive coil 72 includes a first rotary drive coil 721 and a second rotary drive coil 722 disposed on the first plate 41. The first rotary drive magnet 711 and the first rotary drive coil 721 are disposed opposite each other along the first axis, and the second rotary drive magnet 712 and the second rotary drive coil 722 are disposed opposite each other along the first axis, so as to cooperate with each other to drive the movable carrier 50 to rotate relative to the base 10.
[0122] In some embodiments, such as Figure 6 and Figure 10 As shown, the position sensing element 73 and the rotation driving magnet 71 are opposite each other along the third axis direction. The distance between the position sensing element 73 and the rotation driving magnet 71 along the third axis direction is smaller than the distance between the rotation driving magnet 71 and the circuit board 40 along the third axis direction. Specifically, the position sensing element 73 includes a first rotation sensing element 731 and a second rotation sensing element 732, which are electrically connected to the conductive member 20, respectively. The first rotation sensing element 731 is located on the side wall 131 of the first base, so that it is arranged opposite to the first rotation driving magnet 711 along the third axis direction to obtain the first rotation magnetic field signal of the first rotation driving magnet 711. The second rotation sensing element 732 is located on the side wall 132 of the second base, so that it is arranged opposite to the second rotation driving magnet 712 along the third axis direction to obtain the second rotation magnetic field signal of the second rotation driving magnet 712. Then, the rotation stroke of the movable carrier 50 around its rotation axis is calculated by the first rotation magnetic field signal and the second rotation magnetic field signal.
[0123] It is worth mentioning that the first rotation sensing element 731 and the second rotation sensing element 732 are located on the first base sidewall 131 and the second base sidewall 132, respectively. The first rotation driving coil 721 and the second rotation driving coil 722 are located on the first plate 41 fixed to the bottom wall 12 of the base. The first rotation driving magnet 711 and the second rotation driving magnet 712 are located on the bottom surface of the movable carrier 50. This arrangement can help avoid interference between the various components while ensuring smooth rotation of the movable carrier 50 and accurate sensing of the position of the movable carrier 50.
[0124] Furthermore, such as Figure 10As shown, the circuit board 40 includes a second plate 42 disposed on the outer side of the base sidewall 13. The second plate 42 is electrically connected to the conductive element 20, and thus conducts through the conductive element 20 to the first rotation sensing element 731 and the second rotation sensing element 732. Specifically, the second plate 42 is fixed to the outer side of the first base sidewall 131 or the outer side of the second base sidewall 132. When the second plate 42 is fixed to the outer side of the first base sidewall 131, the distance between the second plate 42 and the first rotation driving magnet 711 along the third axis is greater than the distance between the first rotation sensing element 731 and the first rotation driving magnet 711 along the third axis. When the second plate 42 is fixed to the outer side of the second base sidewall 132, the distance between the second plate 42 and the second rotation driving magnet 712 along the third axis is greater than the distance between the second rotation sensing element 732 and the second rotation driving magnet 712 along the third axis.
[0125] It should be understood that since the second circuit board 40 is fixed to the outer side of the base sidewall 13, if the position sensing element 73 is mounted on the circuit board 40, the position sensing element 73 will be far away from the rotation drive magnet 71. If the circuit board 40 is bent so that part of the circuit board 40 is embedded in the base sidewall 13, and the position sensing element 73 is mounted on the part of the circuit board 40 embedded in the base sidewall 13, although the distance between the position sensing element 73 and the rotation drive magnet 71 can be reduced, the circuit board 40 will be bent repeatedly and intensively, which will greatly increase the risk of the circuit board 40 breaking and reduce the production yield of the reflective module. In this embodiment, the conductive element 20 is embedded in the base sidewall 13. Therefore, the conductive element 20 is closer to the center of the receiving space 11 than the second plate 42 which is fixed to the outer side of the base sidewall 13. In other words, it is closer to the rotation drive magnet 71. Welding the position sensing element 73 to the conductive element 20 helps to reduce the distance between the position sensing element 73 and the rotation drive magnet 71, thereby increasing the magnetic field signal strength of the rotation drive magnet 71 acquired by the position sensing element 73.
[0126] In some embodiments, such as Figure 3 and Figure 7 As shown, each conductive component 20 includes a first conductive branch 21 and a second conductive branch 22 embedded in the side wall 13 of the base. The first conductive branch 21 and the second conductive branch 22 are arranged opposite to each other along the third axis direction. The first conductive branch 21 or the second conductive branch 22 is electrically connected to the second plate 42.
[0127] Specifically, such as Figure 6 and Figure 10As shown, the first conductive branch 21 is embedded in the side wall 131 of the first base, and the first rotation sensing element 731 is welded to the first conductive branch 21; the second conductive branch 22 is embedded in the side wall 132 of the second base, and the second rotation sensing element 732 is welded to the second conductive branch 22. The second plate 42 is disposed on the side wall 131 of the first base and electrically connected to the first conductive branch 21 to achieve conduction between the second plate 42 and the conductive element 20; or the second plate 42 is disposed on the side wall 132 of the second base and electrically connected to the second conductive branch 22 to achieve conduction between the second plate 42 and the conductive element 20. This application does not impose specific limitations on this.
[0128] In some embodiments, such as Figure 6 and Figure 7 As shown, the first conductive branch 21 is bent at the first position 211 and the second position 212. The first conductive branch 21 is covered by the base sidewall 13 at the second position 212. The first conductive branch 21 is recessed towards the receiving space 11 along the third axis at the first position 211, so as to be exposed on the base sidewall 13 and electrically connected to the position sensing element 73. That is, in the third axis direction, the first position 211 is closer to the center of the receiving space 11 than the second position 212. The first rotation sensing element 731 is electrically connected to the exposed portion of the first conductive branch 21 at the first position 211, so that the first rotation sensing element 731 and the first rotation driving magnet 711 are arranged opposite each other along the third axis direction.
[0129] In at least one instance, such as Figure 6 and Figure 7 As shown, the first base sidewall 131 includes a first base portion 1311 and a second base portion 1312 arranged along a second axis. The first base portion 1311 is disposed opposite to the movable carrier 50 along a third axis, and the second base portion 1312 is disposed opposite to the intermediate frame 60 along a third axis. The outer surfaces of the first base portion 1311 and the second base portion 1312 are coplanar, and the inner surface of the first base portion 1311 is closer to the center of the receiving space 11 than the inner surface of the second base portion 1312. Furthermore, the portion of the first conductive branch 21 located at the second position 212 is embedded in the second base portion 1312, and the portion of the first conductive branch 21 located at the first position 211 is embedded in the first base portion 1311, and is disposed close to the inner surface of the first base portion 1311; thereby making the first rotation sensing element 731 welded to the first position 211 closer to the first rotation driving magnet 711 along the third axis direction, thereby increasing the magnetic field signal strength of the first rotation driving magnet 711 acquired by the first rotation sensing element 731.
[0130] In some embodiments, such as Figure 6 and Figure 7As shown, the second conductive branch 22 is bent at positions 421 and 522. At position 522, the second conductive branch 22 is covered by the base sidewall 13. At position 421, the second conductive branch 22 is recessed towards the receiving space 11 along the third axis, so as to be exposed on the base sidewall 13 and electrically connected to the position sensing element 73. That is, in the third axis direction, position 421 is closer to the center of the receiving space 11 than position 522. The second rotation sensing element 732 is electrically connected to the exposed portion of the second conductive branch 22 at position 421, so that the second rotation sensing element 732 and the second rotation driving magnet 712 are arranged opposite each other along the third axis direction.
[0131] In at least one instance, such as Figure 6 and Figure 7 As shown, the second base sidewall 132 includes a third base portion 1321 and a fourth base portion 1322 arranged along the second axis. The third base portion 1321 is disposed opposite to the movable carrier 50 along the third axis, and the fourth base portion 1322 is disposed opposite to the intermediate frame 60 along the third axis. The outer surfaces of the third base portion 1321 and the fourth base portion 1322 are coplanar, and the inner surface of the third base portion 1321 is closer to the center of the receiving space 11 than the inner surface of the fourth base portion 1322. Furthermore, the portion of the second conductive branch 22 located at the fifth position 222 is embedded in the fourth base portion 1322, and the portion of the second conductive branch 22 located at the fourth position 221 is embedded in the third base portion 1321, and is disposed close to the inner side of the third base portion 1321; thereby making the second rotation sensing element 732, which is welded to the third position 213, closer to the second rotation driving magnet 712 along the third axis direction, thereby increasing the magnetic field signal strength of the second rotation driving magnet 712 acquired by the second rotation sensing element 732.
[0132] In some embodiments, such as Figure 6 and Figure 10As shown, the first base sidewall 131 has a first groove 1413 for accommodating the first rotation sensing element 731. A portion of the first conductive branch 21 located at the first position 211 is exposed within the first groove 1413, allowing it to be electrically connected to the first rotation sensing element 731. Specifically, the first conductive branch 21 is covered by the second base portion 1312 at the second position 212, which improves the connection strength and reliability between the first conductive branch 21 and the first base sidewall 131. Further, the first groove 1413 is located in the first base portion 1311, and at least a portion of the surface of the first conductive branch 21 at the first position 211 is exposed on the bottom surface of the first groove 1413. The first rotation sensing element 731 is disposed within the first groove 1413 and welded to the exposed surface of the first conductive branch 21. It should be understood that the first rotation sensing element 731 is disposed in the first groove 1413, thereby the first base sidewall 131 can protect the first sensing element and help avoid damage to the first rotation sensing element 731.
[0133] It is worth mentioning that the opening of the first groove 1413 can face the inner side of the first base portion 1311 or the outer side of the first base portion 1311, and this application does not impose a specific limitation on this. In at least one embodiment, the opening of the first groove 1413 faces the outer side of the first base portion 1311 to facilitate subsequent inspection, maintenance and replacement of the first rotation sensing element 731; in other words, the first rotation sensing element 731 can be operated directly without removing other devices such as the reflective element 300 and the movable carrier 50 from the receiving space 11, which helps to avoid affecting other devices in the receiving space 11.
[0134] In some embodiments, such as Figure 6 and Figure 10 As shown, the second base sidewall 132 has a second groove 1423 for accommodating the second rotation sensing element 732. A portion of the second conductive branch 22 located at the fourth position 221 is exposed within the second groove 1423, allowing for electrical connection with the second rotation sensing element 732. Specifically, the second conductive branch 22 is covered by the fourth base portion 1322 at the fifth position 222, which improves the connection strength and reliability between the second conductive branch 22 and the second base sidewall 132. Further, the second groove 1423 is located in the third base portion 1321, and at least a portion of the surface of the second conductive branch 22 at the fourth position 221 is exposed on the bottom surface of the second groove 1423. The second rotation sensing element 732 is disposed within the second groove 1423 and welded to the exposed surface of the second conductive branch 22. It should be understood that the second rotation sensing element 732 is disposed in the second groove 1423, thereby the second base sidewall 132 can protect the second sensing element and help avoid damage to the second rotation sensing element 732.
[0135] It is worth mentioning that the opening of the second groove 1423 can face the inner side of the third base portion 1321 or the outer side of the third base sidewall 133, and this application does not impose any specific limitation on this. In at least one embodiment, the opening of the second groove 1423 faces the outer side of the third base sidewall 133 to facilitate subsequent inspection, maintenance and replacement of the second rotation sensing element 732.
[0136] It is understandable that if the distance between the rotating drive magnet 71 and the position sensing element 73 is reduced by moving the rotating drive magnet 71 toward the base sidewall 13 along the third axis, the size of the movable carrier 50 along the third axis will increase, which in turn will increase the overall size of the reflection module along the third axis, which is not conducive to the miniaturization of the periscope camera module. In addition, it will also increase the mass of the movable carrier 50, requiring a larger driving force to drive the movable carrier 50 to rotate, resulting in a decrease in the control accuracy and response speed of the reflection module.
[0137] In this embodiment, such as Figure 6 and Figure 10 As shown, by providing a first base portion 1311 and a third base portion 1321 protruding towards the center of the receiving space 11, and by having the first conductive branch 21 and the second conductive branch 22 recessed towards the receiving space 11 at the first position 211 and the fourth position 221 respectively, the position sensing element 73 can be recessed towards the center of the receiving space 11 without increasing the external dimensions of the base 10. In other words, based on the miniaturization design of the periscope camera module, the position sensing element 73 is brought closer to the rotating drive magnet 71 on the movable carrier 50, thereby increasing the magnetic field signal strength of the rotating drive magnet 71 acquired by the position sensing element 73.
[0138] In some embodiments, such as Figure 3 and Figure 7 As shown, the first conductive branch 21 is also bent at the third position 213. At the third position 213, the first conductive branch 21 protrudes outward from the receiving space 11 along the third axis direction, so as to be exposed on the outer side of the first base sidewall 131 and electrically connected to the second plate 42. That is, in the third axis direction, the third position 213 is farther away from the center of the receiving space 11 than the second position 212. One side surface of the first conductive branch 21 at the third position 213 is exposed on the outer side of the first base sidewall 131. The second plate 42 is fixed to the outer side of the first base sidewall 131 and welded to the exposed surface of the first conductive branch 21.
[0139] Alternatively, the second conductive branch 22 may be bent at the sixth position, where it protrudes outward from the receiving space 11 along the third axis to expose the outer surface of the second base sidewall 132 and be electrically connected to the second plate 42. That is, the sixth position is further from the center of the receiving space 11 than the fifth position 222 in the third axis direction. One side of the second conductive branch 22 at the sixth position is exposed on the outer surface of the second base sidewall 132, and the second plate 42 is fixed to the outer surface of the second base sidewall 132 and welded to the exposed surface of the second conductive branch 22.
[0140] In at least one instance, such as Figure 7 As shown, the conductive parts 20 and the circuit board 40 are connected at the same side wall of the base 10. For example, each conductive part 20 is connected to the second plate 42 through the part of the first conductive branch 21 at the third position 213, or each conductive part 20 is connected to the second plate 42 through the part of the second conductive branch 22 at the sixth position. This simplifies the circuit connection of the base 1 and also helps to improve the welding efficiency of the circuit board 40 and the conductive parts 20.
[0141] In some embodiments, such as Figure 3 As shown, each conductive element 20 also includes a third conductive branch 23, which is embedded in the bottom wall 12 or the side wall 13 of the base. The third conductive branch 23 is connected between the first conductive branch 21 and the second conductive branch 22 and is electrically connected to the first conductive branch 21 and the second conductive branch 22, so that the arrangement of each conductive element 20 in the base 10 is more concentrated and compact.
[0142] In at least one embodiment, the third conductive branch 23 is embedded in the bottom wall 12 of the base. Thus, after the conductive component 20 is bent, the third conductive branch 23 can be located in the horizontal plane, while the first conductive branch 21 and the second conductive branch 22 are located in the vertical plane. The third conductive branch 23 can play a role in positioning and supporting the conductive component 20 when it is bent, thereby reducing the risk of twisting deformation or displacement of the conductive component 20 when it is bent, which is beneficial to improving the product yield.
[0143] In some embodiments, such as Figure 10 and Figure 13 As shown, the circuit board 40 also includes a third plate 43 disposed on the outer side of the base sidewall 13. The third plate 43 and the second plate 42 are disposed opposite each other along the third axis direction. The third plate 43 and the second plate 42 extend toward the photosensitive module 200 of the periscope camera module along the second axis direction, and the third plate 43 and the second plate 42 are respectively connected to the photosensitive circuit board 201 of the photosensitive module 200. The first plate 41 is connected between the second plate 42 and the third plate 43 and is electrically connected to the second plate 42 and the third plate 43.
[0144] In at least one embodiment, such as Figure 10 and Figure 16 As shown, the second plate 42 is fixed to the outer side of the first base sidewall 131 and is electrically connected to the surface of the first conductive branch 21 exposed at the third position 213. Furthermore, the second plate 42 extends along the second axis toward the photosensitive module 200, thus communicating with the photosensitive circuit board 201 of the photosensitive module 200. In other words, the first rotation sensing element 731 and the second rotation sensing element 732 can be electrically connected to the photosensitive circuit board 201 through the conductive element 20 and the second plate 42. The third plate 43 is fixed to the outer side of the second base sidewall 132 and extends along the second axis toward the photosensitive module 200, thus communicating with the photosensitive circuit board 201 of the photosensitive module 200. Consequently, the first rotation drive coil 721 and the second rotation drive coil 722 can be electrically connected to the photosensitive circuit board 201 through the first plate 41 and the third plate 43. It should be understood that the position sensing element 73 and the rotation drive coil 72 are connected to the photosensitive circuit board 201 through the second plate 42 and the third plate 43, respectively. This helps to avoid the wiring on a certain plate being too dense, thereby reducing the manufacturing difficulty of the circuit board 40. It also makes the pins on the photosensitive circuit board 201 that are used to connect with the circuit board 40 more evenly distributed.
[0145] In some embodiments, such as Figures 13-15 As shown, the reflection module also includes a pitch drive magnet 74 and a pitch drive coil 75. Specifically, the pitch drive magnet 74 is fixed to the surface of the intermediate frame 60 facing the third base sidewall 133. The circuit board 40 also includes a fourth plate 44 disposed on the outer side of the base sidewall 13, specifically, the fourth plate 44 is fixed to the outer side of the third base sidewall 133. The fourth plate 44 is flexibly connected and electrically connected to the first plate 41, the second plate 42, or the third plate 43. The pitch drive coil 75 is disposed on and electrically connected to the fourth plate 44, and thus the pitch drive coil 75 and the pitch drive magnet 74 are arranged opposite each other along the second axis direction, suitable for cooperating to drive the intermediate frame 60 to rotate relative to the base 10 about the third axis A3. In at least one embodiment, the fourth plate 44 is connected and electrically connected to the third plate 43, so that the pitch drive coil 75 can be electrically connected to the photosensitive circuit board 201 through the fourth plate 44 and the third plate 43.
[0146] In at least one embodiment, such as Figures 13-15As shown, the pitch drive magnet 74 includes a first pitch drive magnet 741 and a second pitch drive magnet 742. Specifically, the first pitch drive magnet 741 and the second pitch drive magnet 742 are spaced apart and symmetrically arranged on the back side of the intermediate frame 60, that is, on the surface of the intermediate frame 60 facing away from the reflective element 300 along the second axis direction. The long side of the pitch drive coil 75 is parallel to the third axis direction, so it is arranged opposite to the first pitch drive magnet 741 and the second pitch drive magnet 742 along the second axis direction. In other words, the first pitch drive magnet 741 and the second pitch drive magnet 742 share a pitch drive coil 75 to cooperate in driving the intermediate frame 60 to rotate relative to the base 10 around the third axis A3.
[0147] It is worth mentioning that the pitch drive coil 75 may also include a first pitch drive coil disposed opposite to the first pitch drive magnet 741 and a second pitch drive coil disposed opposite to the second pitch drive magnet 742. This application does not impose specific limitations on this.
[0148] In some embodiments, such as Figure 13 As shown, the reflection module also includes a pitch sensing element 76, which is disposed on the fourth plate 44 and electrically connected to the fourth plate 44. The pitch sensing element 76 and the pitch driving magnet 74 are disposed opposite to each other along the second axis, so that the pitch sensing element 76 can acquire the magnetic field signal of the pitch driving magnet 74 to sense the rotational stroke of the intermediate frame 60 around the third axis A3.
[0149] It is worth mentioning that, such as Figure 1 As shown, a third groove 1331 is also provided on the side wall 133 of the third base. The third groove 1331 can accommodate the pitch sensing element 76 to reduce the distance between the pitch sensing element 76 and the pitch driving magnet 74 along the second axis, thereby increasing the magnetic field signal strength of the pitch driving magnet 74 acquired by the pitch sensing element 76 and compensating for the possible decrease in sensing linearity or attenuation of magnetic field signal due to the increase in rotation angle.
[0150] In some embodiments, such as Figure 17 As shown, the intermediate frame 60 includes an integrally formed frame body 61, a frame back 62, and a frame side 63. Specifically, the frame body 61 is located between the movable carrier 50 and the base bottom wall 12 along the first axis direction, thus supporting the movable carrier 50. The frame back 62 is located between the movable carrier 50 and the third base side wall 133 along the second axis direction. The pitch drive magnet 74 is fixed to the surface of the frame back 62 facing the third base side wall 133, so that it is arranged opposite to the pitch drive coil 75 and the pitch drive magnet 74 on the fourth plate 44 along the second axis direction.
[0151] Furthermore, such as Figure 10 and Figure 17 As shown, the frame side 63 includes a first extension arm 631 and a second extension arm 632 connected to the frame back 62. The first extension arm 631 and the second extension arm 632 are located on opposite sides of the frame back 62 along the third axis, and extend along the second axis. Specifically, the first extension arm 631 is disposed opposite to the first base portion 1311 along the first axis, and the second extension arm 632 is disposed opposite to the third base portion 1321 along the first axis, so as to make the structure of the reflective module more compact and to reduce the size of the reflective module along the third axis.
[0152] Furthermore, such as Figure 10 As shown, the pitch support portion 82 includes a first pitch support member 821 and a second pitch support member 822 spaced apart along the third axis. The first pitch support member 821 is sandwiched between the first extension arm 631 and the first base portion 1311, and the second pitch support member 822 is sandwiched between the second extension arm 632 and the third base portion 1321. Thus, the first pitch support member 821 and the second pitch support member 822 can support the intermediate frame 60 to rotate around the third axis A3.
[0153] In some embodiments, such as Figure 12 , Figures 15-17 As shown, the bottom 54 of the carrier includes an upper concave portion 541 located in the middle, and lower convex portions 542 located on both sides of the upper concave portion 541 along the third axis direction. A mating space 543 is formed between the upper concave portion 541 and the two lower convex portions 542, which can accommodate at least a portion of the frame body 61. This makes the structure between the movable carrier 50 and the frame body 61 more compact, which is beneficial to reducing the size of the reflective module along the first axis direction and lowering the shoulder height of the periscope camera module. Furthermore, a clearance space 64 is formed between the frame body 61 and the frame side portion 63, which extends through the first direction. The lower convex portion 542 of the movable carrier 50 can pass through the clearance space 64 to be arranged opposite to the base bottom wall 12 along the first axis direction. The rotary drive magnet 71 is disposed on the bottom surface of the lower convex portion 542 to be arranged opposite to the rotary drive coil 72 on the first plate 41 along the first axis direction.
[0154] In at least one instance, such as Figure 12 and Figure 16As shown, the bottom surface of the lower protrusion 542 is provided with a rotating magnet groove 5421 for accommodating the rotating drive magnet 71. The rotating magnet groove 5421 penetrates the surface of the lower protrusion 542 facing the base sidewall 13. In other words, the surface of the rotating drive magnet 71 facing the base sidewall 13 can be exposed in the lower protrusion 542, so as to reduce the distance between the rotating drive magnet 71 and the position sensing element 73, and to help avoid the lower protrusion 542 blocking the magnetic field of the rotating drive magnet 71, thereby improving the magnetic field signal strength of the rotating drive magnet 71 acquired by the position sensing element 73.
[0155] It should be understood that the rotating support 81 is sandwiched between the upper surface of the upper recess 541 and the frame body 61. Along the first axis, there is a height difference between the rotating support 81 and the rotating drive magnet 71. In other words, from the second axis, the position of the rotating support 81 is higher than the position of the rotating drive magnet 71. There is a large lever arm between the two. Thus, while the driving force generated by the rotating drive magnet 71 and the rotating drive coil 72 remains unchanged, the driving torque can be further increased, which is beneficial to realize the large-angle rotation of the movable carrier 50 around the second axis A2, such as a rotation of more than ±5°.
[0156] Furthermore, viewed from the first axis direction, the line connecting the center of the first rotating drive magnet 711 and the center of the second rotating drive magnet 712 constitutes the line of action of the driving force. The virtual line where the center of the first rotating support 811 and the center of the second rotating support 812 are located is the second axis A2. The line of action of the driving force is perpendicular to the second axis A2, thereby making the direction of the driving force tangent to the direction of the lever arm. This helps to avoid the driving force from generating a component force along the second axis direction, thereby improving the utilization rate of the driving force. It also helps to prevent the moving carrier 50 from moving along the second axis direction, making the imaging of the periscope camera module more stable.
[0157] It is worth mentioning that, viewed from the second axis direction, as Figure 16 As shown, the center of the rotating support 81, the center of the first rotating drive magnet 711, and the center of the second rotating drive magnet 712 form an isosceles triangle. It should be understood that the first rotating drive magnet 711 and the second rotating drive magnet 712 are symmetrically arranged with respect to the second axis A2 formed by the rotating support 81. Therefore, the torques generated by the first rotating drive magnet 711 and the second rotating drive magnet 712 on the rotating support 81 are equal in magnitude and opposite in direction, enabling the movable carrier 50 to remain balanced and rotate only under the combined action of the rotating drive magnet 71 and the rotating drive coil 72.
[0158] In some embodiments, such as Figure 12 , Figure 15 and Figure 17As shown, the movable carrier 50 also includes a carrier back 53 connected to the carrier body 51. The carrier back 53 extends towards the frame back 62 along the second axis direction. A clearance groove 621 is provided on the frame back 62, allowing the carrier back 53 to extend into the clearance groove 621, so that the carrier back 53 and the frame body 61 are positioned opposite each other along the first axis direction. Further, the rotating support portion 81 includes a first rotating support member 811 and a second rotating support member 812 spaced apart along the second axis direction. The first rotating support member 811 is sandwiched between the bottom surface of the carrier back 53 and the frame body 61, and the second rotating support member 812 is sandwiched between the bottom surface of the upper recess 541 and the frame body 61. Thus, the first rotating support member 811 and the second rotating support member 812 can support the movable carrier 50 to rotate relative to the intermediate frame 60 around the second axis A2. It should be understood that this arrangement allows the structure of the movable carrier 50 and the intermediate frame 60 to be more compact, reducing the size of the reflective module along the second direction, thereby facilitating a reduction in the length of the periscope camera module.
[0159] In at least one embodiment, the rotation support 81 and the pitch support 82 are located in the same plane perpendicular to the first axis. Specifically, the first rotation support 811 and the second rotation support 812 are arranged along the second axis, with the second axis A2 passing through the first rotation support 811 and the second rotation support 812; the first pitch support 821 and the second pitch support 822 are arranged along the third axis, with the third axis A3 passing through the first pitch support 821 and the second pitch support 822. The second axis A2 coincides with the optical axis of the lens module 100 of the periscope camera module, and the second axis A2 intersects with the third axis A3. In other words, both the rotation support 81 and the pitch support 82 are located in the plane containing the third axis A3 and the optical axis. It is worth noting that the coincidence of the optical axis of the lens module 100 with the second axis A2 simplifies the organization and calibration steps of the periscope camera module, thereby improving the production efficiency and yield of the periscope camera module.
[0160] It is understandable that the rotation support 81 and the pitch support 82 are coplanar, allowing them to share a reference plane for assembly. This helps reduce assembly tolerances and improves assembly accuracy of the reflector module. Furthermore, the rotation support 81 and the pitch support 82 support the movable carrier 50 and the intermediate frame 60 respectively in the same plane. Therefore, in the event of a drop or impact to the periscope camera module, the impact force can be dispersed by the rotation support 81 and the pitch support 82, preventing the impact force from concentrating on a single rotation or pitch support component and causing damage. This improves the structural reliability of the reflector module and extends its service life.
[0161] In at least one embodiment, the center of the reflecting surface on the reflecting element 300 is located in the plane containing the rotation support 81 and the pitch support 82. That is, the intersection of the second axis A2 and the third axis A3 coincides with the reflection center, and the reflecting surface rotates around its center point. This helps to avoid lateral or longitudinal translation of the image on the imaging plane, keeps the image center fixed, and helps to prevent the introduction of new coma, trapezoidal distortion, or image plane tilt during optical image stabilization, thereby improving image quality.
[0162] In some embodiments, such as Figure 9 As shown, the reflection module also includes a rotating magnetic suction part 91, which includes a first magnetic element 911 and a second magnetic element 912 arranged opposite to each other along a first axis. One of the first magnetic element 911 and the second magnetic element 912 is disposed on the movable carrier 50, and the other is disposed on the intermediate frame 60. Through the magnetic attraction between the first magnetic element 911 and the second magnetic element 912, the rotating support part 81 can be reliably clamped between the movable carrier 50 and the intermediate frame 60.
[0163] Among them, along the second axis direction, such as Figure 9 As shown, the rotating magnetic attraction part 91 is located between the first rotating support member 811 and the second rotating support member 812. It should be understood that the virtual line where the center of the first rotating support member 811 and the center of the second rotating support member 812 are located is the second axis A2. The magnetic attraction between the first magnetic member 911 and the second magnetic member 912 acts directly on or near the second axis A2, which helps to avoid generating additional deflection torque on the movable carrier 50, thereby reducing the risk of the movable carrier 50 shifting or tilting.
[0164] Furthermore, the magnetic attraction between the first magnetic component 911 and the second magnetic component 912 can also provide pre-pressure to the rotating support 81. The direction of the pre-pressure is along the radial direction of the first rotating support 811 and the second rotating support 812, which can enhance the contact stability of the first rotating support 811 and the second rotating support 812, reduce the risk of the first rotating support 811 and the second rotating support 812 falling off or causing local wear, thereby improving the structural stability and reliability of the reflective module, and making the reflective module have better impact and vibration resistance.
[0165] Furthermore, along the third axis, the rotating magnetic attraction part 91 is located between the first rotating driving magnet 711 and the second rotating driving magnet 712. It should be understood that maintaining a certain distance between the rotating magnetic attraction part 91 and the rotating driving magnet 71 helps to prevent the magnetic field of the rotating magnetic attraction part 91 from interfering with the magnetic field of the rotating driving magnet 71, thereby improving the driving linearity and driving accuracy of the reflection module. In addition, it also helps to prevent the magnetic field of the rotating magnetic attraction part 91 from interfering with the position sensing element 73, thereby improving the sensing accuracy of the position sensing element 73.
[0166] Furthermore, along the second axis, the distance from the center of the rotating magnetic attraction part 91 to the third axis A3 is greater than the distance from the center of the rotating driving magnet 71 to the third axis A3. In other words, the lever arm of the magnetic attraction force generated by the rotating magnetic attraction part 91 to the third axis A3 is greater than the lever arm of the gravity generated by the rotating driving magnet 71 to the third axis A3. Therefore, even if the magnetic attraction force is relatively small, a larger torque can be generated through the longer lever arm to reset the movable carrier 50. This configuration achieves both good magnetic attraction and reset effects while reducing the size of the first magnetic component 911 and the second magnetic component 912.
[0167] It is worth mentioning that, such as Figure 9 As shown, the second axis A2 passes through the space between the first magnetic element 911 and the second magnetic element 912. In other words, the second axis A2 does not coincide with the first magnetic element 911 and the second magnetic element 912. In this way, the magnetic attraction force can act on the contact surface between the rotating support part 81 and the movable carrier 50 and the intermediate frame 60, and it is beneficial to avoid the magnetic attraction force acting on the second axis A2. This helps to prevent the rotating support part 81 from being locked due to excessive magnetic attraction force, and ensures that the movable carrier 50 can rotate normally around the second axis A2.
[0168] In at least one embodiment, such as Figure 9 As shown, the first magnetic component 911 is implemented as a magnetic magnet fixed to the movable carrier 50, and the second magnetic component 912 is implemented as a magnetic yoke embedded in the intermediate frame 60.
[0169] In some embodiments, such as Figure 9 and Figure 10 As shown, the reflection module also includes a pitch magnetic attraction part 92, which includes a third magnetic element 921 and a fourth magnetic element 922 disposed opposite to each other along the first axis. One of the third magnetic element 921 and the fourth magnetic element 922 is disposed on the intermediate frame 60, and the other is disposed on the base bottom wall 12. Through the magnetic attraction between the third magnetic element 921 and the fourth magnetic element 922, the pitch support part 82 can be reliably clamped between the intermediate frame 60 and the base bottom wall 12.
[0170] Among them, along the third axis direction, such as Figure 10 As shown, the pitch magnetic attraction part 92 is located between the first pitch support member 821 and the second pitch support member 822; and, viewed from the first axis direction, the center of the pitch magnetic attraction part 92 is located on the line connecting the first pitch support member 821 and the second pitch support member 822. It should be understood that the virtual line containing the center of the first pitch support member 821 and the center of the second pitch support member 822 is the third axis A3. The magnetic attraction force between the third magnetic member 921 and the fourth magnetic member 922 acts directly on the third axis A3 or near the third axis, which helps to avoid generating additional deflection torque on the intermediate frame 60, thereby reducing the risk of the intermediate frame 60 shifting or tilting.
[0171] Furthermore, the magnetic attraction between the third magnetic component 921 and the fourth magnetic component 922 can also provide pre-pressure to the pitch support 82. The direction of the pre-pressure is along the radial direction of the first pitch support 821 and the second pitch support 822, which can enhance the contact stability of the first pitch support 821 and the second pitch support 822, reduce the risk of the first pitch support 821 and the second pitch support 822 falling off or causing local wear, thereby improving the structural stability and reliability of the reflector module, and making the reflector module have better impact and vibration resistance.
[0172] Furthermore, along the second axis direction, such as Figure 9 As shown, the pitch magnetic attraction part 92 and the pitch driving magnet 74 are spaced at a certain distance, which helps to avoid the magnetic field of the pitch magnetic attraction part 92 from interfering with the magnetic field of the pitch driving magnet 74, thereby improving the driving linearity and driving accuracy of the reflection module; in addition, it also helps to avoid the magnetic field of the pitch magnetic attraction part 92 from interfering with the pitch sensing element 76, thereby improving the sensing accuracy of the pitch sensing element 76.
[0173] Furthermore, the magnetic attraction force of the driving magnetic attraction unit on the intermediate frame 60 and the magnetic attraction force of the pitch magnetic attraction unit 92 on the intermediate frame 60, along the first axis direction, can form a "magnetic attraction chain" that runs through the movable carrier 50, the intermediate frame 60, and the base bottom wall 12, thereby improving the structural stability of the reflective module. In addition, viewed from the third axis direction, the magnetic attraction force of the driving magnetic attraction unit on the intermediate frame 60 and the magnetic attraction force of the pitch magnetic attraction unit 92 on the intermediate frame 60 are misaligned along the first axis direction. This helps to prevent the intermediate frame 60 from being locked due to excessive magnetic attraction force, and ensures that the intermediate frame 60 can rotate normally around the third axis A3.
[0174] In at least one embodiment, such as Figure 9 and Figure 10As shown, the second magnetic element 912 is implemented as a magnetic magnet fixed to the intermediate frame 60, and the second magnetic element 912 is implemented as a magnetic yoke embedded in the bottom wall 12 of the base.
[0175] A method for manufacturing a periscope camera module base 1, used to manufacture the aforementioned periscope camera module base 1, characterized in that it comprises:
[0176] a. Provide a first strip for forming a plurality of conductive elements 20, wherein each conductive element 20 includes a first conductive branch 21, a second conductive branch 22 and a third conductive branch 23 connected in sequence in a horizontal plane. The first conductive branch 21 has a first position 211 and a second position 212 that can be bent, and the second conductive branch 22 has a fourth position 221 and a fifth position 222 that can be bent.
[0177] b. The first conductive branch 21 and the second conductive branch 22 are bent for the first time to form a first semi-finished product. The first conductive branch 21 is bent vertically at least once at the first position 211 and the second position 212, and the first conductive branch 21 has a height difference in the vertical direction at the first position 211 and the second position 212. The second conductive branch 22 is bent vertically at least once at the fourth position 221 and the fifth position 222, and the second conductive branch 22 has a height difference in the vertical direction at the fourth position 221 and the fifth position 222.
[0178] c. Perform the first injection molding, injection molding a first molding part 141 at the first position 211 and the second position 212. The first molding part 141 has a first groove 1413 formed, and the first conductive branch 21 is partially exposed in the first groove 1413 at the first position 211. Then, injection molding a second molding part 142 at the fourth position 221 and the fifth position 222. The second molding part 142 has a second groove 1423 formed, and the second conductive branch 22 is partially exposed in the second groove 1423 at the fourth position 221.
[0179] d. Provide a position sensing element 73, which is horizontally disposed in the first groove 1413 and the second groove 1423, and electrically connected to the first conductive branch 21 and the second conductive branch 22; specifically, the position sensing element 73 includes a first rotation sensing element 731 electrically connected to the first conductive branch 21, and a second rotation sensing element 732 electrically connected to the second conductive branch 22.
[0180] e. The conductive component 20 is bent a second time, so that the first conductive branch 21, the first forming part 141, the second conductive branch 22, the second forming part 142 and the position sensing element 73 are simultaneously changed from horizontal to vertical to form a second semi-finished product.
[0181] f. The second semi-finished product is injection molded to form a second injection molding part 15. The second injection molding part 15 covers at least a portion of the conductive component 20 and the outer periphery of the first molding part 141 and the second molding part 142 to form a base bottom wall 12 and a base side wall 13, thereby obtaining the base 1 of the periscope camera module.
[0182] In at least one embodiment, in step b, after bending the first conductive branch 21 and the second conductive branch 22, the portion of the first conductive branch 21 at the first position 211 and the portion of the second conductive branch 22 at the fourth position 221 are both located in the first plane; the portion of the first conductive branch 21 at the second position 212 and the portion of the second conductive branch 22 at the fifth position 222 are both located in the second plane; and the third conductive branch 23 is located in the second plane. The first plane and the second plane are skewed and parallel, meaning the first plane and the second plane have a height difference in the vertical direction. Further, as... Figures 3-5 As shown, after the conductive element 20 is bent for the second time in step e, the portion of the first conductive branch 21 at the first position 211 and the portion of the second conductive branch 22 at the fourth position 221 can be symmetrically arranged with the second axis A2 of the base 1 as the center line. This makes the first rotation sensing element 731 and the second rotation sensing element 732 symmetrically arranged with the second axis A2 of the base 1 as the center line. This helps to ensure that the magnetic field signals detected by the first rotation sensing element 731 and the second rotation sensing element 732 of the moving carrier 50 rotating in other directions are opposite, so that they can cancel each other out to improve the position sensing accuracy.
[0183] This should be understandable, such as Figure 4 and Figure 5 As shown, in step c, the first molding part 141 and the second molding part 142 are formed by the first injection molding, which pre-fixes the bent parts of the first conductive branch 21 and the second conductive branch 22. This helps to avoid the first conductive branch 21 and the second conductive branch 22 from twisting, deforming or shifting due to the impact of the injection material during the second injection molding, thereby improving the positional accuracy of the conductive component 20 in the base 10, and improving the positional accuracy of the first rotation sensing element 731 and the second rotation sensing element 732 welded to the conductive component 20 on the base 10.
[0184] In step e, after the conductive element 20 is bent for the second time, the distance between the first position 211 and the fourth position 221 is smaller than the distance between the second position 212 and the fifth position 222. This makes the first rotation sensing element 731 closer to the first rotation driving magnet 711 in the accommodating space 11, and the second rotation sensing element 732 closer to the second rotation driving magnet 712 in the accommodating space 11. This allows for the acquisition of a stronger magnetic field signal in a more compact space, which is beneficial for maintaining high-precision position sensing throughout the entire rotation stroke of the movable carrier 50.
[0185] In step f, the base sidewall 13 includes a first base sidewall 131 and a second base sidewall 132 disposed opposite to each other along the third axis direction, wherein the first molding part 141 is located on the first base sidewall 131 and the second molding part 142 is located on the second base sidewall 132.
[0186] It should be understood that the second injection molding part 15 only covers the outer periphery of the first molding part 141 and the second molding part 142. In other words, the second injection molding part 15 avoids the outer and inner sides of the first molding part 141 and the outer and inner sides of the second molding part 142. This helps to avoid increasing the wall thickness of the first base sidewall 131 and the second base sidewall 132, thereby reducing the external dimensions of the base 1 along the third axis, thus reducing the width of the periscope camera module; and making the accommodating space 11 have a larger dimension along the third axis.
[0187] It is worth mentioning that the second injection part 15 also avoids the first groove 1413 and the second groove 1423, thereby exposing the first rotation sensing element 731 in the first groove 1413 to the first base sidewall 131, and exposing the second rotation sensing element 732 in the second groove 1423 to the second base sidewall 132, so as to facilitate subsequent inspection, repair or replacement of the first rotation sensing element 731 and the second rotation sensing element 732.
[0188] In some embodiments, the first conductive branch 21 further includes a third position 213. In step b, the first conductive branch 21 is bent for the first time. Along the thickness direction of the conductive member 20, the first conductive branch 21 is arranged in opposite planes and parallel to the second position 212 at the third position 213. The plane where the second position 212 is located is located between the plane where the first position 211 is located and the plane where the third position 213 is located.
[0189] Furthermore, such as Figure 4 and Figure 5As shown, in step c, the first forming portion 141 is also formed at the third position 213, and the surface of the first conductive member 20 at the third position 213 is exposed on the first forming portion 141. It should be understood that in step f, the first conductive branch 21 is exposed on the outer side of the first base sidewall 131 at the third position 213, so as to be in communication with the second plate 42 which is fixed to the outer side of the base sidewall 13.
[0190] In some embodiments, such as Figure 4 and Figure 5 As shown, the first molding part 141 includes an integrally molded first platform part 1411 and a first raised part 1412. The first platform part 1411 covers the portions of the first conductive branch 21 located at the second position 212 and the third position 213. The surface of the first conductive branch 21 at the third position 213 is exposed on the first platform part 1411. The first raised part 1412 covers the portion of the first conductive branch 21 located at the first position 211 and forms a first groove 1413.
[0191] It should be understood that in step e, after the conductive element 20 is bent for the second time, the first raised portion 1412 protrudes toward the second conductive branch 22. In other words, the first raised portion 1412 protrudes toward the center of the receiving space 11 of the base 1 to form the first base portion 1311, and the first conductive branch 21 in the first raised portion 1412 is recessed toward the receiving space 11 at the first position 211. This allows the first rotation sensing element 731 to be recessed toward the center of the receiving space 11 without increasing the external dimensions of the base 10, so that the first rotation sensing element 731 is closer to the first rotation driving magnet 711 in the receiving space 11, thereby achieving higher precision position sensing.
[0192] In some embodiments, such as Figure 4 and Figure 5 As shown, the second molding part 142 includes an integrally formed second platform part 1421 and a second raised part 1422. The second platform part 1421 covers the portion of the second conductive branch 22 located at the fifth position 222; the second raised part 1422 covers the portion of the second conductive branch 22 located at the fourth position 221 and forms a second groove 1423.
[0193] It should be understood that in step e, after the conductive element 20 is bent for the second time, the second raised portion 1422 protrudes towards the first conductive box. In other words, the second raised portion 1422 protrudes towards the center of the receiving space 11 of the base 1 to form the third base portion 1321. The second conductive branch 22 in the second raised portion 1422 is recessed towards the receiving space 11 at the fourth position 221. This allows the second rotation sensing element 732 to be recessed towards the center of the receiving space 11 without increasing the external dimensions of the base 10, so that the second rotation sensing element 732 is closer to the second rotation driving magnet 712 in the receiving space 11, thereby achieving higher precision position sensing.
[0194] In some embodiments, such as Figure 4 and Figure 5 As shown, in step c, the first injection molding of the first semi-finished product also forms a third molding part 143. The third molding part 143 covers at least a portion of the third conductive branch 23, thereby pre-fixing the third conductive branch 23. This helps to prevent the third conductive branch 23 from twisting, deforming or shifting due to the impact of the injection material during the second injection molding, thereby improving the positional accuracy of the third conductive branch 23 in the base 10.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
