Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of optical devices, and specifically relates to an optical lens, a periscope camera module and an electronic device. Background Art
[0002] In order to improve the shooting quality of electronic devices, electronic devices are equipped with periscope camera modules. The periscope camera modules have a large zoom range, thus greatly improving the shooting performance of electronic devices.
[0003] In related technologies, a periscope camera module includes an optical lens, a photosensitive chip, and a module housing, both of which are housed within the housing. The optical lens typically includes a reflective prism and a prism mount, with one side of the reflective surface of the reflective prism resting on the prism mount. During the specific shooting process, ambient light enters the reflective prism through the light-incident surface of the reflective prism, is then reflected by the reflective surface of the reflective prism to the light-outgoing surface, and is then received by the photosensitive chip.
[0004] However, the prism and prism seat in the optical lens are adhered by adhesive structures such as glue and double-sided tape. When observing the internal structure of the periscope camera module from the outside to the inside, the edge of the prism, the adhesive structure, and even the edge of the prism seat can be seen at an angle. The appearance of these structures has a certain color difference, resulting in a multi-layer appearance structure with different colors in the edge area of the optical lens, which reduces the appearance consistency of the periscope camera module and thus leads to poor appearance performance of the periscope camera module. Summary of the Invention
[0005] The purpose of the embodiments of the present application is to provide an optical lens, a periscope camera module and an electronic device that can solve the technical problem of poor appearance performance of the periscope camera module.
[0006] In order to solve the above technical problems, this application is implemented as follows: In a first aspect, the present application discloses an optical lens, comprising a lens barrel and a reflecting prism; The lens barrel has a first surface, a second surface, and a third surface distributed along its circumference, the first surface having a first limiting structure, the first limiting structure enclosing a light entrance hole, and the second surface or the third surface having a mounting opening; the lens barrel is provided with an accommodating cavity communicating with both the light entrance hole and the mounting opening; wherein the accommodating cavity is used to accommodate the reflective prism, and the mounting opening is used to assemble the reflective prism into the accommodating cavity; the first limiting structure is used to limit the reflective prism; The reflective prism has a light incident surface, a light emitting surface and a reflecting surface. When the reflective prism is located in the accommodating cavity, the light incident surface cooperates with the first surface, the light emitting surface cooperates with the second surface, and the reflecting surface cooperates with the third surface.
[0007] In the second aspect, the present application discloses a periscope camera module, including a first lens unit, a second lens unit, a motor, a module housing and a photosensitive chip, wherein the first lens unit is the above-mentioned optical lens; the first lens unit, the second lens unit, the motor and the photosensitive chip are all located in the module housing, the first lens unit and the photosensitive chip are located on opposite sides of the second lens unit, and the motor is connected to the first lens unit for driving the first lens unit to move.
[0008] In a third aspect, the present application discloses an electronic device, comprising a device body and the above-mentioned periscope camera module, wherein the periscope camera module is arranged on the device body.
[0009] In an embodiment of the present application, the first surface of the lens barrel has a first limiting structure, which encloses a light entrance hole. The second surface or the third surface of the lens barrel has a mounting opening. The reflective prism is installed in the accommodating cavity through the mounting opening. When the reflective prism is located in the accommodating cavity, the light entrance surface of the reflective prism cooperates with the first surface, the light exit surface cooperates with the second surface, and the reflective surface cooperates with the third surface. In this solution, the first limiting structure on the first surface can limit the reflective prism, so that the edge area of the light entrance surface is covered by the first limiting structure. Therefore, when observing the internal structure of the periscope camera module from the outside to the inside, the edge position of the reflective prism is not easy to see. Only the first limiting structure of the lens barrel and the area where the light entrance surface of the prism is exposed through the light entrance hole can be seen. Therefore, the risk of the edge area of the optical lens having a multi-layer appearance structure with different colors is avoided, thereby improving the appearance consistency of the periscope camera module, which is conducive to improving the appearance performance of the periscope camera module.

DETAILED DESCRIPTION
[0012] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0013] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects and are not used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of this application can be implemented in an order other than that illustrated or described herein. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.
[0014] Below, in conjunction with the accompanying drawings, the optical lens, periscope camera module and electronic device provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.
[0015] Please refer to Figures 1 to 7The embodiment of the present application discloses an optical lens 100 , which includes a lens barrel 110 and a reflecting prism 120 .
[0016] The lens barrel 110 is a mounting base for the optical lens 100. The lens barrel 110 has a first surface 111, a second surface 112, and a third surface 113 distributed along its circumference. Here, it can be understood that the first surface 111, the second surface 112, and the third surface 113 are the circumferential surfaces of the lens barrel 110. In this case, the first surface 111, the second surface 112, and the third surface 113 are located on different sides of the circumference of the lens barrel 110. In other words, the first surface 111, the second surface 112, and the third surface 113 are respectively located on different sides of the circumference of the lens barrel 110. For example, the second surface 112 and the third surface 113 can be respectively located on two adjacent sides of the first surface 111. Alternatively, the first surface 111 and the third surface 113 can be respectively located on two adjacent sides of the second surface 112.
[0017] The first surface 111 has a first limiting structure 1111, which encloses a light entrance hole 110a. The second surface 112 or the third surface 113 has a mounting opening 110c. The lens barrel 110 has a receiving cavity 116 that is connected to both the light entrance hole 110a and the mounting opening 110c. The receiving cavity 116 is used to accommodate a reflective prism 120, and the mounting opening 110c is used to assemble the reflective prism 120 into the receiving cavity 116. The first limiting structure 1111 is used to limit the position of the reflective prism 120. In this case, the mounting opening 110c and the light entrance hole 110a are located on different sides of the lens barrel 110.
[0018] The first limiting structure 1111 here can be understood as a side wall with a light entrance hole 110a, and the light entrance hole 110a is used to pass light from the external environment. At this time, the external environment light enters the lens barrel 110 through the first surface 111 of the lens barrel 110. Therefore, the first surface 111 faces the user, and the side where the first surface 111 is located is the front of the optical lens 100. The user can directly observe the first surface 111 from the front of the optical lens 100, that is, the user can directly observe the first limiting structure 1111 from the front. The first limiting structure 1111 can be understood as the top of the lens barrel 110, and the mounting opening 110c is opened on a side adjacent to or opposite to the top. Therefore, the mounting opening 110c can be opened at the bottom or side of the lens barrel 110.
[0019] The reflective prism 120 has a light incident surface 121, a light emitting surface 122, and a reflective surface 123. When the reflective prism 120 is located within the accommodating cavity 116, the light incident surface 121 cooperates with the first surface 111, and the side of the reflective prism 120 provided with the light incident surface 121 faces the first surface 111. The light emitting surface 122 cooperates with the second surface 112, and the side of the reflective prism 120 provided with the light emitting surface 122 faces the second surface 112. The reflective surface 123 cooperates with the third surface 113, and the side of the reflective prism 120 provided with the reflective surface 123 faces the third surface 113. During specific operation, external light enters the light incident surface 121 through the light incident hole 110a, and then travels toward the reflective surface 123 via the light incident surface 121. After being reflected by the reflective surface 123, it is emitted from the light emitting surface 122.
[0020] In the embodiment of the present application, the light incident surface 121 is opposite to the first limiting structure 1111. Therefore, in the direction of the reflective prism 120 toward the first surface 111, the light incident surface 121 and the first limiting structure 1111 are limited and cooperated. Since the first limiting structure 1111 is provided with a light entrance hole 110a, the area of the light incident surface 121 opposite to the light entrance hole 110a is exposed, so that external ambient light passes through the light entrance hole 110a and enters the area of the light incident surface 121 opposite to the light entrance hole 110a. At this time, the area of the light incident surface 121 opposite to the light entrance hole 110a is the center area of the light incident surface 121, and the area of the light incident surface 121 opposite to the first limiting structure 1111 is the edge area of the light incident surface 121. Therefore, the first limiting structure 1111 is limited to the edge area of the light incident surface 121. It can also be understood that the first limiting structure 1111 covers the edge area of the light incident surface 121. Of course, it can also be understood here that the area of the light incident hole 110a is smaller than the area of the light incident surface 121. The small area of the light incident hole 110a enables the first limiting structure 1111 to cover the edge area of the light incident surface 121.
[0021] In the embodiment disclosed in the present application, the mounting opening 110c is opened on the second surface 112 or the third surface 113, so the reflective prism 120 is not mounted from the front of the optical lens 100, but is mounted into the lens barrel 110 from the side where the second surface 112 or the third surface 113 is located. Therefore, the reflective prism 120 does not need to be mounted from the first surface 111 of the lens barrel 110, so that the first surface 111 can be provided with a first limiting structure 1111, and the edge area of the light incident surface 121 is covered by the first limiting structure 1111, so that the periscope camera can be mounted on the first surface 111 of the lens barrel 110. Since the first limiting structure 1111 is just pressed on the edge area of the light incident surface 121 when observing the internal structure of the module 200 from the outside to the inside, it is not easy to see the edge position of the reflective prism 120. Only the first limiting structure 1111 of the lens barrel 110 and the central area of the light incident surface 121 can be seen. Therefore, the risk of the edge area of the optical lens 100 having a multi-layer appearance structure with different colors is avoided, thereby improving the appearance consistency of the periscope camera module 200, which is beneficial to improving the appearance performance of the periscope camera module 200.
[0022] In the embodiment disclosed in the present application, the first surface 111 can be the upper side of the lens barrel 110, the reflective prism 120 has the lens barrel 110, and the third surface 113 and the second surface 112 can be the lower side and right side of the lens barrel. In this case, the reflective prism 120 is installed in the lens barrel 110 from the lower end or side of the lens barrel 110. With this design, the edge of the reflective prism 120 and other positions cannot be seen from the outer surface of the module, and only the upper end surface of the lens barrel 110 and the central light-transmitting position of the reflective prism 120 can be seen. For example, the first limiting structure 1111 is exactly pressed on the edge area of the light incident surface 121, and the glue dispensing position of the edge of the reflective prism 120 is exactly blocked by the first limiting structure 1111. Therefore, the user can only observe the first limiting structure 1111 and the central area of the light incident surface 121 from the front of the module, thereby ensuring the consistency of the appearance of the module. At the same time, it can also block unnecessary incident light from entering the interior of the module, improving the problem of stray light.
[0023] In the related art, the edge area of the light-entering surface requires ink silk-screen printing to provide stray light protection. However, the silk-screen printing process is relatively cumbersome, resulting in high manufacturing costs and a long manufacturing cycle for the optical lens 100. Furthermore, this process reduces the yield rate of the reflective prism 120. Furthermore, the color difference between the silk-screen printing ink and the prism base is also large, resulting in poor appearance consistency.
[0024] In the embodiment disclosed in the present application, the edge area of the light incident surface 121 is covered by the first limiting structure 1111 of the lens barrel 110. Therefore, the first limiting structure 1111 can play a role in preventing stray light, thereby eliminating the need for ink silk screen printing on the edge area of the light incident surface 121, thereby simplifying the manufacturing cost of the optical lens 100 and shortening the manufacturing cycle. In addition, the reflective prism 120 does not need to be silk screen printed with ink, which is also beneficial to improving the yield rate of the reflective prism 120. In addition, the user can only see the first limiting structure 1111 and the center area of the light incident surface 121 from the front of the module, without other structures. The first limiting structure 1111 has a single color, which is beneficial to further improve the appearance performance of the optical lens.
[0025] In the above solution, the surface of the lens barrel 110 can be black-plated. At this time, the first limiting structure 1111 is part of the lens barrel 110, so the color of the first limiting structure 1111 is consistent with that of other areas of the lens barrel 110, which is beneficial to further improve the appearance performance of the optical lens 100.
[0026] In the above embodiment, the thickness direction of the first limiting structure 1111 is perpendicular to the first surface 111. In this case, the first limiting structure 1111 has a certain thickness. The first limiting structure 1111 has a first sidewall 1111a, which encloses the aforementioned light entrance hole 110a. Here, the first sidewall 1111a is the hole wall of the light entrance hole 110. In this case, the first sidewall 1111a is likely to reflect external large-angle light into the reflective prism 120, thereby easily affecting the optical performance of the optical lens 100.
[0027] Based on this, in another optional embodiment, the thickness of the first limiting structure 1111 gradually decreases from the edge of the light incident hole 110a toward the center of the light incident hole 110a to form a first sidewall 1111a. In this case, as the thickness of the first limiting structure 1111 decreases from the edge of the light incident hole 110a toward the center of the light incident hole 110a, at least a portion of the first limiting structure 1111 forms an inclined sidewall, and thus the first sidewall 1111a is an inclined structure.
[0028] For example, the first limiting structure 1111 has a first outer surface 1111b facing away from the light incident surface 121 and a first inner surface 1111c facing the light incident surface 121. At this time, in the direction from the edge of the light incident hole 110a to the center of the light incident hole 110a, at least a portion of the first outer surface 1111b of the first limiting structure 1111 is inclined toward the first inner surface 1111c, so that the distance between the first outer surface 1111b and the first inner surface 1111c is reduced. Therefore, at least a portion of the first outer surface 1111b forms an inclined surface, which is the first sidewall 1111a mentioned above. It can also be understood here that in the direction along the first limiting structure 1111 pointing to the light incident surface 121, the distance between the first sidewall 1111a and the central axis of the light incident hole 110a gradually decreases.
[0029] In this solution, the first side wall 1111a is tilted. At this time, the first side wall 1111a can reflect and block external large-angle light, thereby preventing external large-angle light from entering the reflective prism 120, thereby reducing stray light caused by light reflected from the edge of the lens barrel 110, which is beneficial to improving the optical performance of the optical lens 100.
[0030] Furthermore, the angle between the first surface 111 and the first sidewall 1111a can be greater than 0° and less than or equal to 60°. Alternatively, the angle between the first surface 111 and the first sidewall 1111a can be greater than or equal to 120° and less than 180°. This can be understood as meaning that the angle between the first sidewall 1111a and the first surface 111 can be greater than 0° and less than or equal to 60°; and the complementary angle between the first sidewall 1111a and the first surface 111 can be greater than or equal to 120° and less than 180°.
[0031] like Figure 5 As shown, the first surface 111 here can be a horizontal reference plane. In this case, the plane on which one of the first outer surface 1111b and the first inner surface 1111c of the first limiting structure 1111 lies is the horizontal reference plane. Therefore, the angle between the first side wall 1111a and the first surface 111 can be understood as the angle between the first inner surface 1111c or the first outer surface 1111b of the first limiting structure 1111 and the first side wall 1111a.
[0032] This solution can further reduce stray light caused by light reflected from the edge of the lens barrel 110 , thereby further improving the optical performance of the optical lens 100 .
[0033] In another optional embodiment, as Figure 1 As shown, the distance between the edge of the light incident hole 110 a and the edge of the light incident surface 121 is a first distance L1 , and the first distance L1 may be greater than or equal to 0.1 mm.
[0034] This solution ensures a large shielding area between the first limiting structure 1111 and the light incident surface 121, thereby avoiding the risk of exposing the edge of the reflective prism 120. In addition, the large first distance L1 also ensures a large overlap area between the first limiting structure 1111 and the light incident surface 121, thereby ensuring the reliability of the overlap between the first limiting structure 1111 and the reflective prism 120.
[0035] In the above embodiment, the mounting opening 110c can be provided on the second surface 112. In this case, the mounting opening 110c is opposite the light-emitting surface 122 of the reflective prism 120. Therefore, light emitted from the light-emitting surface 122 is emitted out of the lens barrel 110 through the mounting opening 110c. Therefore, the mounting opening 110c provided on the second surface 112 can be used for both mounting the reflective prism 120 and emitting light emitted by the reflective prism 120. Therefore, the mounting opening 110c here is also referred to as the light-emitting hole 110b.
[0036] In another alternative embodiment, the third surface 113 may have an installation opening 110c. In this case, the reflective prism 120 is installed into the lens barrel 110 from the side where the third surface 113 is located. The second surface 112 may have a second limiting structure 1121, which may enclose the light exit hole 110b and be used to limit the position of the reflective prism 120.
[0037] At this time, the second limiting structure 1121 and the reflecting prism 120 are positioned in a direction toward the second surface 112. Because the second limiting structure 1121 includes a light exit hole 110b, the area of the light exit surface 122 opposite the light exit hole 110b is exposed, allowing light reflected from the reflecting surface 123 to pass through the light exit surface 122 and exit the reflecting prism 120, and then exit the lens barrel 110 through the light exit hole 110b. At this time, the area of the light exit surface 122 opposite the light exit hole 110b is the center area of the light exit surface 122, and the area of the light exit surface 122 opposite the second limiting structure 1121 is the edge area of the light exit surface 122. Therefore, the second limiting structure 1121 is positioned relative to the edge area of the light exit surface 122. It can also be understood that the second limiting structure 1121 covers the edge area of the light exit surface 122. Of course, it can also be understood here that the area of the light exit hole 110b is smaller than the area of the light exit surface 122. The small area of the light exit hole 110b enables the second limiting structure 1121 to cover the edge area of the light exit surface 122.
[0038] In this solution, the second limiting structure 1121 can bear against the edge of the light-emitting surface 122, thereby improving assembly reliability. Furthermore, the second limiting structure 1121 can also prevent stray light from entering the edge of the light-emitting surface 122, thereby further optimizing the structure of the optical lens 100. Furthermore, the third surface 113 is neither used for light emission nor for light input. Therefore, locating the mounting opening 110c on the third surface 113 can further prevent external stray light from entering the reflective prism 120, thereby improving optical performance.
[0039] In the above embodiment, the thickness direction of the second limiting structure 1121 is perpendicular to the second surface 112. In this case, the second limiting structure 1121 has a certain thickness. The second limiting structure 1121 has a second sidewall 1121a, which encloses the aforementioned light exit hole 110b. Here, the second sidewall 1121a is the hole wall of the light exit hole 110b. In this case, the second sidewall 1121a is likely to reflect external large-angle light into the reflective prism 120, thereby easily affecting the optical performance of the optical lens 100.
[0040] In another optional solution, the thickness direction of the second limiting structure 1121 can be perpendicular to the second surface 112, and the thickness of the second limiting structure 1121 gradually decreases along the edge of the light exit hole 110b toward the center of the light exit hole 110b to form a second side wall 1121a. Figure 6 As shown, in the process of the thickness of the second limiting structure 1121 decreasing from the edge of the light exit hole 110b toward the center of the light exit hole 110b, at least part of the second limiting structure 1121 forms an inclined side wall, so the second side wall 1121a is an inclined surface.
[0041] like Figure 6 As shown, the second limiting structure 1121 has a second outer surface 1121b facing away from the light-emitting surface 122 and a second inner surface 1121c facing the light-emitting surface 122. At this time, in the direction from the edge of the light-emitting hole 110b to the center of the light-emitting hole 110b, at least a portion of the second outer surface 1121b of the second limiting structure 1121 is inclined toward the second inner surface 1121c, so that the distance between the second outer surface 1121b and the second inner surface 1121c is reduced. Therefore, at least a portion of the second outer surface 1121b forms an inclined surface, which is the second sidewall 1121a mentioned above. It can also be understood here that the distance between the second sidewall 1121a and the central axis of the light-emitting hole 110b gradually decreases in the direction from the second limiting structure 1121 to the light-emitting surface 122.
[0042] In this solution, the second side wall 1121a is tilted. At this time, the second side wall 1121a can reflect and block external large-angle light, thereby preventing external large-angle light from entering the reflective prism 120, thereby reducing stray light caused by light reflected from the edge of the lens barrel 110, which is beneficial to improving the optical performance of the optical lens 100.
[0043] Furthermore, the angle between the second surface 112 and the second sidewall 1121a can be greater than 0° and less than or equal to 60°; alternatively, the angle between the second surface 112 and the second sidewall 1121a can be greater than or equal to 120° and less than 180°. This can be understood as meaning that the angle between the second sidewall 1121a and the second surface 112 can be greater than 0° and less than or equal to 60°; and the complementary angle between the second sidewall 1121a and the second surface 112 can be greater than or equal to 120° and less than 180°.
[0044] like Figure 6 As shown, the second surface 112 here can be a vertical reference plane. In this case, the plane on which one of the second outer surface 1121b and the second inner surface 1121c of the second limiting structure 1121 lies is the vertical reference plane. Therefore, the angle between the second side wall 1121a and the second surface 112 can be understood as the angle between the second inner surface 1121c or the second outer surface 1121b of the second limiting structure 1121 and the second side wall 1121a.
[0045] This solution can further reduce stray light caused by light reflected from the edge of the lens barrel 110 , thereby further improving the optical performance of the optical lens 100 .
[0046] In another optional solution, the distance between the edge of the light exit hole 110 b and the edge of the light exit surface 122 may be a second distance, and the second distance may be greater than or equal to 0.1 mm.
[0047] In this solution, the second distance is relatively large, which also ensures a larger overlapping area between the second limiting structure 1121 and the light emitting surface 122 , thereby ensuring the reliability of the overlapping between the second limiting structure 1121 and the reflective prism 120 .
[0048] In another optional embodiment, the lens barrel 110 may further include a fourth surface 114 and a fifth surface 115, wherein the first surface 111, the second surface 112, and the third surface 113 are all located between the fourth surface 114 and the fifth surface 115 and are arranged sequentially along the circumference of the fourth surface 114 and the fifth surface 115. The fourth surface 114 may include a first side panel 1141, and the fifth surface 115 may include a second side panel 1151. The first and second limiting structures 1111 and 1121 are both located between the first and second side panels 1141 and 1151, and the first and second side panels 1141 and 1151 are respectively connected to opposite sides of the first and second limiting structures 1111 and 1121. In this case, the first and second limiting structures 1111, 1121, the first and second side panels 1141, and 1151 may enclose the aforementioned accommodating chamber 116.
[0049] The reflective prism 120 further has a first side surface 124 and a second side surface 125 opposite to each other. The light incident surface 121, the light emitting surface 122, and the reflective surface 123 can all be located between the first side surface 124 and the second side surface 125 and sequentially connected along the circumference of the first side surface 124 and the second side surface 125. The first side surface 124 can be bonded to the first side plate 1141, and the second side surface 125 can be bonded to the second side plate 1151.
[0050] This solution can further increase the bonding area between the reflective prism 120 and the lens barrel 110 , thereby further improving the connection strength between the reflective prism 120 and the lens barrel 110 , avoiding the risk of the reflective prism 120 falling out of the lens barrel 110 , and thus improving the safety and reliability of the optical lens 100 .
[0051] Optionally, the first side surface 124 and the first side panel 1141 as well as the second side surface 125 and the second side panel 1151 may be bonded together by adhesive structures such as glue or double-sided tape.
[0052] In another optional embodiment, the first side plate 1141 may be provided with a glue dispensing groove, which may be filled with glue. In this case, the glue dispensing groove can increase the thickness of the glue, thereby further improving the reliability of the bonding.
[0053] Similarly, the second side panel 1151 may also be provided with a glue dispensing groove. Figure 2 The white strip structure on the cross-sectional view of the lens barrel 110 is the glue dispensing groove.
[0054] In one embodiment, a portion of the edge of the first side panel 1141 on the side facing away from the second limiting structure 1121 and a portion of the edge of the second side panel 1151 on the side facing away from the second limiting structure 1121 can enclose the aforementioned mounting opening 110c. In this case, the first limiting structure 1111, the second limiting structure 1121, the first side panel 1141, and the second side panel 1151 can enclose the aforementioned accommodating cavity 116. The portion of the edge between the first side panel 1141 and the second side panel 1151 forms the mounting opening 110c. This embodiment simplifies the structure of the lens barrel 110, thereby further reducing the manufacturing cost of the optical lens 100. In another optional embodiment, the clearance between the inner surface of the accommodating cavity 116 and the outer surface of the reflective prism 120 can be greater than or equal to 0.01 mm. This embodiment can prevent interference between the reflective prism 120 and the lens barrel 110, thereby ensuring that the reflective prism 120 can be installed in the accommodating cavity 116 of the lens barrel 110.
[0055] Furthermore, the reflective prism 120 can be installed in the accommodating cavity 116 through the installation opening 110 c along the first direction Z, and the area of the cross section of the accommodating cavity 116 perpendicular to the first direction Z gradually decreases along the first direction Z.
[0056] At this time, when the reflecting prism 120 is assembled to the lens barrel 110, the deepest part of the lens barrel 110 where the reflecting prism 120 contacts is smaller, and when the reflecting prism 120 is assembled to the lens barrel 110, the shallowest part of the lens barrel 110 where the reflecting prism 120 contacts is larger. The accommodating cavity 116 has a structure that is smaller inside and larger outside, thereby further ensuring that the reflecting prism 120 can be installed in the accommodating cavity 116.
[0057] In another optional solution, the first limiting structure 1111 can be subjected to a super black plating process, thereby further improving the overall appearance of the optical lens 100.

The first lens unit 210, the second lens unit 220, the motor 230, and the photosensitive chip 250 may all be located within the module housing 240. The first lens unit 210 and the photosensitive chip 250 may be located on opposite sides of the second lens unit 220. The motor 230 may be connected to the first lens unit 210 to drive the first lens unit 210 to move. The first lens unit 210 is the aforementioned optical lens 100. The first lens unit 110 may be an optical image stabilization module. The motor 230 drives the first lens unit 210 to move during shooting, thereby compensating for the shake caused by shooting in an oblique direction. The second lens unit 220 is an autofocus module. The motor 230 can drive the second lens to move closer to or away from the first lens unit 210 to achieve the focusing function.
[0060] During the specific shooting process, light passes through the module housing 240 , and then passes through the first lens unit 210 and the second lens unit 220 in sequence before being incident on the photosensitive chip 250 to achieve the shooting function.
[0061] Based on the periscope camera module 200 disclosed in the embodiment of the present application, the embodiment of the present application also discloses an electronic device, and the disclosed electronic device includes the periscope camera module 200 described in any of the above embodiments.
