Description

Technical Field

[0001] This application belongs to the field of electronic device design technology, specifically relating to a camera component and an electronic device. Background Technology

[0002] Currently, electronic devices (such as mobile phones and tablets) are becoming increasingly ubiquitous in people's daily lives. These devices are typically equipped with camera components to enable video recording and meet users' photography needs. With technological advancements, people are increasingly accustomed to using electronic devices to photograph objects at a distance, necessitating camera components with telephoto capabilities. However, the technology involved in implementing telephoto functionality in camera components is challenging. Achieving telephoto capabilities would easily result in excessively long camera components, making it difficult to integrate them into electronic devices. Summary of the Invention

[0003] This invention discloses a camera component and an electronic device to alleviate the problem that camera components in related technologies have difficulty in achieving telephoto functionality.

[0004] To alleviate the above-mentioned technical problems, the present invention provides the following technical solution: In a first aspect, this application discloses a camera assembly, which includes a first lens, a first reflector, a second reflector, and a photosensitive chip. The first lens and the second reflector are both disposed on the first side of the first reflector. The first reflector has a first reflective surface and a second reflective surface. The first lens is opposite to the first reflective surface. The light-incident surface of the second reflector is opposite to the second reflective surface. The light-exiting surface of the second reflector is opposite to the photosensitive chip.

[0005] Secondly, this application discloses an electronic device, which includes a device housing and the camera assembly described above, wherein the camera assembly is at least partially disposed within the device housing.

[0006] The technical solution adopted in this invention can achieve the following technical effects: The camera assembly disclosed in this application improves upon the structure of related camera assemblies by placing both the first lens and the second reflector on a first side of the first reflector. The first lens is positioned opposite the first reflective surface of the first reflector, and the light-incident surface of the second reflector is opposite the second reflective surface of the first reflector. The light-exiting surface of the second reflector is opposite the photosensitive chip. This allows the first reflector to receive light passing through the first lens and reflect it back to the second reflector, which then reflects the light onto the photosensitive chip. This structure extends the projection path of light passing through the first lens through the first and second reflectors, resulting in a longer focal length for the first lens and enabling the camera assembly to achieve telephoto capabilities.

[0007] Furthermore, this structure achieves telephoto functionality through a first reflector and a second reflector, thereby avoiding excessively increasing the length of the camera assembly. This facilitates the mounting of the camera assembly onto electronic devices and reduces the impact of the camera assembly on the layout of electronic devices. Consequently, it enables the mounting of the camera assembly onto electronic devices while simultaneously achieving telephoto functionality. Attached Figure Description

It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and are not limited in number; for example, a first object can be one or more.

[0012] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0013] Please refer to Figures 1 to 11 This application discloses a camera assembly, which includes a first lens 210, a first reflector 310, a second reflector 320, and a photosensitive chip 410.

[0014] The first lens 210 and the photosensitive chip 410 are the core components for imaging in the camera assembly, while the first reflector 310 and the second reflector 320 are the core components for achieving telephoto functionality in the camera assembly. Both the first lens 210 and the second reflector 320 are located on the first side of the first reflector 310. The first reflector 310 has a first reflecting surface 311 and a second reflecting surface 312. The first lens 210 is opposite to the first reflecting surface 311, so that the first reflecting surface 311 can receive and reflect light A passing through the first lens 210. The light-incident surface of the second reflector 320 is opposite to the second reflective surface 312, and the light-exiting surface of the second reflector 320 is opposite to the photosensitive chip 410. The second reflector 320 can be located between the first lens 210 and the photosensitive chip 410. This allows the second reflective surface 312 to receive and reflect light A, so that light A can enter the second reflector 320 through the light-incident surface of the second reflector 320, and after being reflected by the second reflector 320, light A can be projected onto the photosensitive chip 410 through the light-exiting surface of the second reflector 320.

[0015] In other words, during the specific operation, the first reflecting surface 311 receives the light ray A passing through the first lens 210 and reflects it to the second reflecting element 320 via the second reflecting surface 312. The light ray A reflected by the first reflecting surface 311 enters the second reflecting element 320 through its light-incident surface. The second reflecting element 320 reflects the light ray A onto the photosensitive chip 410. The light ray A reflected by the second reflecting surface 320 is then projected onto the photosensitive chip 410 through its light-outceasing surface. The photosensitive surface of the photosensitive chip 410 receives the light signal, causing it to convert the light signal into an electrical signal, thereby achieving image formation. Specifically, the first reflecting surface 311 can directly reflect the light ray A onto the second reflecting element 320, or it can indirectly reflect the light ray A onto the second reflecting element 320 via the third reflecting surface 313, as described later.

[0016] Optionally, the first reflecting surface 311 and the second reflecting surface 312 can be symmetrically distributed, and the axis of symmetry of the first reflecting surface 311 and the second reflecting surface 312 can be parallel to the optical axis of the first lens 210, so that the light ray A entering the first reflecting element 310 and the light ray A exiting the second reflecting element 320 can be parallel to each other, thereby improving the optical path accuracy of the light ray A and thus achieving a better imaging effect.

[0017] The camera assembly disclosed in this application improves the structure of camera assemblies in related technologies by both the first lens 210 and the second reflector 320 on the first side of the first reflector 310. The first lens 210 is positioned opposite the first reflecting surface 311 of the first reflector 310, and the light-incident surface of the second reflector 320 is opposite the second reflecting surface 312 of the first reflector 310. The light-exiting surface of the second reflector 320 is opposite the photosensitive chip 410. This allows the first reflecting surface 311 to receive light A passing through the first lens 210 and reflect it through the second reflecting surface 312 to the second reflector 320, which in turn reflects light A onto the photosensitive chip 410. This structure extends the projection path of light A passing through the first lens 210 through the first reflector 310 and the second reflector 320, giving the first lens 210 a longer focal length and enabling the camera assembly to achieve telephoto functionality.

[0018] Furthermore, this structure achieves the telephoto function through the first reflector 310 and the second reflector 320, thereby avoiding excessively increasing the length of the camera assembly, which facilitates the assembly of the camera assembly to the electronic device and helps to reduce the impact of the camera assembly on the layout of the electronic device. Thus, it is possible to achieve the telephoto function while assembling the camera assembly on the electronic device.

[0019] In addition, this structure can avoid extending the projection path of the light ray A passing through the first lens 210 by excessively increasing the size of the first reflector 310 in the optical axis direction of the first lens 210, thereby achieving a telephoto function. The optical axis direction of the first lens 210 can be parallel to the thickness direction of the camera assembly or parallel to the thickness direction of the electronic device. That is, the thickness direction of the camera assembly can be parallel to the thickness direction of the electronic device, thereby reducing the thickness of the camera assembly and minimizing its impact on the thickness of the electronic device, thus facilitating the thinner and lighter design of the electronic device.

[0020] Furthermore, the camera assembly may also include a bracket 110. The bracket 110 can be a basic component of the camera assembly. The bracket 110 is used to provide mounting positions for other components of the camera assembly; of course, the bracket 110 can also form some functional spaces or structures. In the embodiments of this application, the bracket 110 is used to provide a mounting base for the first lens 210, the first reflector 310, the second reflector 320, and the photosensitive chip 410.

[0021] The first reflector 310 can be disposed on the first side of the bracket 110, and the side of the first reflector 310 facing the bracket 110 can be the first side of the first reflector 310. The first lens 210, the second reflector 320 and the photosensitive chip 410 can all be disposed on the second side of the bracket 110 away from the first reflector 310, thereby facilitating the installation of the first lens 210, the first reflector 310, the second reflector 320 and the photosensitive chip 410.

[0022] The bracket 110 may be provided with a second clearance hole 111. The light-incident surfaces of the first lens 210, the first reflective surface 311, the second reflective surface 312, and the second reflector 320 may all be opposite to the second clearance hole 111, so that the light A passing through the first lens 210 is projected onto the first reflective surface 311 through the second clearance hole 111, and the light A reflected by the second reflective surface 312 can pass through the second clearance hole 111 and be projected onto the second reflector 320, thereby facilitating the propagation of light A.

[0023] Specifically, the first lens 210 can be directly and movably connected to the bracket 110, or indirectly and movably connected to the bracket 110 through the second lens holder 520, the first carrier 530, the second carrier 540 and the second housing 130 described later; the first reflector 310 can be directly connected to the bracket 110 by means of bonding, snap-fitting or other methods; the second reflector 320 and the photosensitive chip 410 can be directly connected to the bracket 110 by means of bonding, snap-fitting or other methods, or indirectly connected to the bracket 110 through the first housing 120 described later.

[0024] In an alternative technical solution, the camera assembly may further include a second lens 220, which may be disposed between the second reflector 320 and the photosensitive chip 410, and the second lens 220 may move closer to or further away from the photosensitive chip 410 along its optical axis to achieve focusing.

[0025] When the camera assembly includes a bracket 110, the second lens 220 can be slidably connected to the bracket 110 along its optical axis to move closer to or further away from the photosensitive chip 410. Of course, the first lens 210 can be focused by moving relative to the bracket 110 along its optical axis, allowing focusing not only through the first lens 210 but also through the second lens 220. Furthermore, the first and second lenses 210 can cooperate to focus, facilitating more flexible focusing.

[0026] Specifically, the optical axis of the second lens 220 can be perpendicular to the optical axis of the first lens 210, and the second lens 220 can be directly and slidably connected to the bracket 110, or indirectly and slidably connected to the bracket 110 through the first housing 120 described later.

[0027] In a further technical solution, the camera assembly may also include a first housing 120, with the second reflector 320, the second lens 220, and the photosensitive chip 410 all disposed within the first housing 120, which may be located on the first side of the first reflector 310. The second lens 220 may be slidably connected to the first housing 120 along its optical axis, allowing the second lens 220 to move closer to or further away from the photosensitive chip 410 along its optical axis. This facilitates the installation of the second lens 220 and provides protection for the second lens 220 through the first housing 120.

[0028] When the camera assembly includes a bracket 110, the first housing 120 can be disposed on the second side of the bracket 110. The first housing 120 can be connected to the bracket 110 by means of snap-fit, adhesive or other means, so that the second lens 220 can be slidably connected to the bracket 110 along its (i.e. the second lens 220) optical axis direction through the first housing 120, thereby making it easier to install the first housing 120, so as to facilitate the installation of the second lens 220.

[0029] In a further technical solution, the camera assembly may also include a first lens holder 510 disposed within the first housing 120, and the second lens 220 may be fixedly connected to the first lens holder 510 by means of snap-fit, threaded connection, adhesive bonding, etc. The first housing 120 may have a guide structure 121, which may be distributed within the first housing 120. The extending direction of the guide structure 121 may be parallel to the optical axis direction of the second lens 220. The first lens holder 510 may slidably engage with the guide structure 121, that is, the first lens holder 510 may slide along the guide structure 121, thereby driving the second lens 220 to slide along the guide structure 121, and thus enabling the second lens 220 to be slidably connected to the first housing 120 along its (i.e., the second lens 220's) optical axis direction.

[0030] In this structure, the second lens 220 is slidably engaged with the guide structure 121 via the first lens holder 510. This allows the guide structure 121 to guide the first lens holder 510, causing the second lens 220 to slide relative to the guide structure 121 along its optical axis. This minimizes the risk of the second lens 220 shifting during sliding, thus improving the stability of the sliding motion. Simultaneously, the second lens 220 is slidably connected to the first housing 120 via the first lens holder 510, further preventing wear and tear during sliding that could affect the stability of the second lens's operation.

[0031] In one embodiment, the guide structure 121 may include a guide rod 122, and the first lens holder 510 may be provided with a first mating groove 511. The first lens holder 510 can be supported on the guide rod 122 through the first mating groove 511, so that the first lens holder 510 and the guide structure 121 can be slidably engaged. The central axis direction of the guide rod 122 may be parallel to the optical axis direction of the second lens 220, thereby enabling the first lens holder 510 to be easily guided to slide relative to the guide rod 122 along the optical axis direction of the second lens 220. In addition, in order to further improve the sliding stability of the second lens 220, there may be multiple guide rods 122, and correspondingly, there may also be multiple first mating grooves 511. The first lens holder 510 can be slidably supported on multiple guide rods 122 through multiple first mating grooves 511 respectively.

[0032] Optionally, the camera assembly may further include a plurality of first rolling elements 610, and the guide structure 121 may further include a first track 123, the extension direction of which may be parallel to the optical axis direction of the second lens 220. The first lens holder 510 may be supported on the first track 123 by the plurality of first rolling elements 610, and the first lens holder 510 may slide along the first track 123 by the rolling of the plurality of first rolling elements 610, thereby enabling the first lens holder 510 to slidably engage with the guide structure 121 by the rolling of the plurality of first rolling elements 610, thereby facilitating the first lens holder 510 to drive the second lens 220 to move along the optical axis direction of the second lens 220. Specifically, the first rolling element 610 may be a first cylindrical rolling element or a first ball bearing, and the embodiments of this application are not limited thereto.

[0033] In this structure, the first lens holder 510 and the first rolling element 610 have a small contact area, and the first track 123 and the first rolling element 610 also have a small contact area. This results in low friction between the first lens holder 510 and the first rolling element 610, and also low friction between the first track 123 and the first rolling element 610. This helps reduce the resistance when the first lens holder 510 slides, facilitating the sliding of the second lens 220. Furthermore, to further improve the stability of the sliding of the second lens 220, there can be multiple first tracks 123. The first lens holder 510 can be supported on multiple first tracks 123 by multiple first rolling elements 610, allowing the first lens holder 510 to slidably engage with the guide structure 121 through the rolling of the multiple first rolling elements 610.

[0034] In other embodiments, the first lens holder 510 may include a first slide shaft to slide along the first track 123, thereby enabling the first lens holder 510 to slidably engage with the guide structure 121.

[0035] In feasible technical solutions, the first housing 120 may further include a first base 124 and a cover 125. The cover 125 may cover at least a portion of the structure of the first base 124. The cover 125 may be connected to the first base 124 by means of snap-fit, adhesive, or other methods. The guide structure 121, the second reflector 320, the second lens 220, the photosensitive chip 410, and the first lens holder 510 may all be disposed within the first base 124. The guide structure 121 may be fixedly connected to the first base 124 by means of adhesive, snap-fit, or other methods. Of course, the guide structure 121 and the first base 124 may also be an integral structure to simplify the installation steps.

[0036] In addition, the first base 124 may be provided with a third clearance hole 126, which may be opposite to the second clearance hole 111 and the light incident surface of the second reflector 320, so that the light A reflected by the second reflector 312 can pass through the second clearance hole 111 and the third clearance hole 126 in sequence and be projected onto the second reflector 320.

[0037] Furthermore, the camera assembly may also include a first driving mechanism 710 disposed within the first housing 120. The first driving mechanism 710 can be drivenly connected to the second lens 220 to drive the second lens 220 to slide relative to the first housing 120 along its optical axis, thereby facilitating the driving of the second lens 220. Specifically, the first driving mechanism 710 may include a first coil 711 and a first magnetic element 712. The first coil 711 may be disposed in the first housing 120, and the first magnetic element 712 may be connected to the second lens 220 by means of snap-fit, adhesive, etc., so that the second lens 220 can be driven to slide relative to the first housing 120 along its optical axis through the cooperation between the first coil 711 and the first magnetic element 712.

[0038] Optionally, the camera assembly may also include a second circuit board 420, which may be fixed to the first base 124. The first coil 711 may be fixed to the second circuit board 420 by means of bonding, welding or other methods, and may be electrically connected to the second circuit board 420, thereby facilitating the electrical connection of the first coil 711.

[0039] In the embodiments disclosed in this application, the camera assembly may further include a second housing 130, which may be disposed on the first side of the first reflector 310. The first lens 210 is movably disposed on the second housing 130 to facilitate the installation of the first lens 210 and to facilitate the protection of the first lens 210 by the second housing 130.

[0040] When the camera assembly includes a bracket 110, the second housing 130 can be disposed on the second side of the bracket 110. The second housing 130 can be connected to the bracket 110 by means of adhesive bonding, snap-fit, or other methods. The first lens 210 is movably disposed on the second housing 130, thereby indirectly and movably connected to the bracket 110 through the second housing 130. This facilitates the installation of the second housing 130 on the bracket 110, and thus facilitates the movable connection between the first lens 210 and the bracket 110.

[0041] In one embodiment, the camera assembly may further include a second lens holder 520, a first carrier 530, a plurality of second rolling elements 620, and a second drive mechanism 720. The second lens holder 520, the first carrier 530, the plurality of second rolling elements 620, and the second drive mechanism 720 may all be disposed within the second housing 130. The second lens holder 520 and the first lens 210 may be fixedly connected by snap-fitting, adhesive bonding, or other means. The first carrier 530 may include a second track 531 extending along a first direction. The second lens holder 520 may be supported on the second track 531 by the plurality of second rolling elements 620, i.e., the second rolling elements 620 are disposed between the second lens holder 520 and the second track 531. Specifically, the second rolling element 620 may be a second cylindrical rolling element or a second ball bearing; this embodiment does not limit the specific rolling elements.

[0042] The second drive mechanism 720 can be disposed on the second housing 130 to provide power to the camera assembly. Specifically, the second drive mechanism 720 can be connected to the second lens holder 520 and the second housing 130, wherein the second drive mechanism 720 and the second lens holder 520 can be driven to drive the second lens holder 520 to drive the first lens 210 to perform anti-shake movement in the first direction along the second track 531 through the rolling of multiple second rolling elements 620.

[0043] In this structure, the second track 531 provides a mounting base for the second rolling element 620 and guides the second rolling element 620 to roll in the first direction, thereby indirectly guiding the first lens 210 to perform image stabilization movement in the first direction. Furthermore, during operation, when the second drive mechanism 720 drives the second lens mount 520 to move the first lens 210 relative to the second track 531 in the first direction for image stabilization, the second rolling element 620 rolls between the second lens mount 520 and the second track 531.

[0044] In other embodiments, the second lens mount 520 may include a second sliding shaft to slide along the second track 531, thereby causing the second lens mount 520 to drive the first lens 210 to perform image-stabilized motion in a first direction along the second track 531.

[0045] In a further technical solution, the camera assembly may further include a second carrier 540 and a plurality of third rolling elements 630, all of which are disposed within the second housing 130. The second carrier 540 may include a third track 541 extending along a second direction. The first carrier 530 may be supported on the third track 541 by the plurality of third rolling elements 630, and the second lens holder 520 may be supported on the second carrier 540 by the first carrier 530. The second direction may be perpendicular to the first direction. Specifically, the third rolling element 630 may be a third cylindrical rolling element or a third ball bearing; this embodiment of the application does not limit this.

[0046] The second drive mechanism 720 is used to drive the first carrier 530 to move relative to the second carrier 540 in a second direction via the rolling of multiple third rolling elements 630 through the second lens mount 520. Specifically, the second drive mechanism 720 can drive the first carrier 530 to move relative to the second carrier 540 in a second direction through the second lens mount 520, that is, the second drive mechanism 720 can indirectly drive the first carrier 530 to move relative to the second carrier 540 in a second direction through the second lens mount 520, and the second drive mechanism 720 and the second lens mount 520 can move synchronously in the second direction. The first carrier 530 moves relative to the second carrier 540 in the second direction by the rolling of multiple third rolling elements 630 along the third track 541, and the first lens 210 moves relative to the second carrier 540 in the second direction along with the second lens mount 520, thereby achieving image stabilization of the first lens 210 relative to the second carrier 540 in the second direction.

[0047] In this structure, the first lens 210 can perform image stabilization not only in the first direction but also in the second direction, thus achieving multi-dimensional image stabilization. This allows the first lens 210 to perform planar image stabilization, enabling the camera assembly to handle more complex application scenarios. Furthermore, the second drive mechanism 720 can directly drive the third track 541 of the first carrier 530 to move, causing the first carrier 530 to move relative to the second carrier 540 along the second direction. This allows the first carrier 530 to drive the first lens 210 to perform image stabilization in the second direction via the second lens mount 520.

[0048] In other embodiments, the first carrier 530 may include a third slide shaft to slide along a third track 541, thereby enabling the first carrier 530 to move relative to the second carrier 540 in a second direction.

[0049] In an optional technical solution, the camera assembly may further include a plurality of fourth rolling elements 640 disposed within the second housing 130. The second housing 130 may include a fourth track 131 extending in a third direction, which may be distributed within the second housing 130. The plurality of fourth rolling elements 640 may be evenly disposed between the fourth track 131 and the second carrier 540. The second drive mechanism 720 is used to drive the second carrier 540 to perform third-direction image stabilization movement relative to the second housing 130 through the rolling of the plurality of fourth rolling elements 640.

[0050] In the specific operation, the second carrier 540 can perform third-direction image stabilization movement along the fourth track 131 through the rolling of multiple fourth rolling elements 640, thereby performing third-direction image stabilization movement relative to the second housing 130. This, in turn, drives the first carrier 530, the second lens mount 520, and the first lens 210 supported on the second carrier 540 to perform third-direction image stabilization movement relative to the second housing 130. The third direction can be parallel to the optical axis of the first lens 210, and the third direction can be perpendicular to both the second and first directions, meaning that the first, second, and third directions are mutually perpendicular.

[0051] This structure, by further adding a fourth rolling element 640 and a fourth track 131, enables the first lens 210 to perform third-dimensional image stabilization movement, thereby enabling the first lens 210 to perform spatial image stabilization movement, and thus enabling more-dimensional image stabilization movement, which is conducive to further enriching the application scenarios of camera components.

[0052] In other embodiments, the second carrier 540 may include a fourth sliding shaft to slide along the fourth track 131, thereby driving the first carrier 530, the second lens holder 520 and the first lens 210 to perform third-direction image stabilization relative to the second housing 130.

[0053] Optionally, the second carrier 540 can be a bracket or shell structure with a first accommodating space, and the first lens 210, the second lens holder 520, the second rolling element 620, the first carrier 530 and the third rolling element 630 can all be installed in the second carrier 540 (i.e. located in the first accommodating space), so that when the second carrier 540 moves along the third direction, it can drive the first lens 210, the second lens holder 520, the second rolling element 620, the first carrier 530 and the third rolling element 630 installed in the second carrier 540 to move together along the third direction, so as to indirectly achieve the image stabilization of the first lens 210 in the third direction.

[0054] In this embodiment, the second driving mechanism 720 may include a coil assembly and a magnetic assembly. The coil assembly may be fixed to the second base 132, and the magnetic assembly may be fixed to the first lens 210. The coil assembly may be opposite to the magnetic assembly and may be used to drive the first lens 210 to move along a first direction, a second direction, and a third direction, respectively, via the magnetic assembly. In this structure, the coil assembly and the magnetic assembly do not need to contact each other, thereby reducing wear between them and extending the service life of the second driving mechanism 720. Furthermore, the second driving mechanism 720 operates with lower noise, which helps to achieve quiet operation of the camera assembly and thus improves the user experience.

[0055] In the embodiments disclosed in this application, the second housing 130 may further include a lens cover 133 and a second base 132. The lens cover 133 may be fixed to the second base 132 and may form a second accommodating space with the second base 132. The first carrier 530, the third rolling element 630, the second carrier 540, the fourth rolling element 640, the first lens 210, and the second lens holder 520 may all be disposed in the second accommodating space. The lens cover 133 may be provided with a fourth clearance hole 134 opposite to the first lens 210.

[0056] Furthermore, the camera assembly may also include a buffer 140, which may be located on the side of the second lens holder 520 facing the fourth clearance hole 134, and may be connected to the second carrier 540 by means of snap-fit, adhesive, or other methods. When the first lens 210 moves along the third motion and approaches the fourth clearance hole 134, the buffer 140 can provide cushioning to reduce the impact force during collision. Specifically, at least a portion of the material of the buffer 140 may be elastic rubber or silicone, and this embodiment of the application does not limit this.

[0057] When the first lens 210 is capable of image stabilization movement along a first direction, a second direction, and a third direction, the coil assembly may include a second coil 721, a third coil 723, and a fourth coil 725. The magnetic assembly may include a second magnetic element 722, a third magnetic element 724, and a fourth magnetic element 726. The second coil 721, the third coil 723, and the fourth coil 725 may all be disposed on the second base 132. The second magnetic element 722 and the third magnetic element 724 may be connected to the second lens holder 520 by means of snap-fitting, bonding, or other methods. The fourth magnetic element 726... It can be connected to the second carrier 540 by means of snap-fit, adhesive or other means, and the second coil 721, the third coil 723 and the fourth coil 725 can be opposite to the second magnetic element 722, the third magnetic element 724 and the fourth magnetic element 726 respectively, so that the first lens 210 can be driven to perform image stabilization movement along the first direction, the second direction and the third direction respectively by the cooperation between the second coil 721 and the second magnetic element 722, the cooperation between the third coil 723 and the third magnetic element 724 and the cooperation between the fourth coil 725 and the fourth magnetic element 726.

[0058] Optionally, the camera assembly may also include a third circuit board 430, which may be fixed to the second base 132. The second coil 721, the third coil 723, and the fourth coil 725 may be fixed to the third circuit board 430 by means of bonding, welding, etc., and may be electrically connected to the third circuit board 430, thereby facilitating the electrical connection of the second coil 721, the third coil 723, and the fourth coil 725.

[0059] In one embodiment, the first reflector 310 may further have a third reflective surface 313, which may be disposed on the side of the first reflective surface 311 facing the first lens 210. The side of the first reflective surface 311 facing the first lens 210 and the side of the second reflective surface 312 facing the light-incident surface of the second reflector 320 may be the same side, that is, the third reflective surface 313 may be disposed on the side of the first reflective surface 311 and the second reflective surface 312 facing the bracket 110.

[0060] Of course, the third reflective surface 313 avoids the first lens 210 and the second reflector 320 respectively, so as to avoid obstructing the light A passing through the first lens 210 from being projected onto the first reflective surface 311, and to avoid obstructing the light A reflected by the second reflective surface 312 from entering the second reflector 320. Optionally, in the optical axis direction of the first lens 210, the third reflective surface 313 may be located between the first lens 210 and the second reflector 320.

[0061] In the specific working process, the third reflective surface 313 is used to receive the light ray A reflected by the first reflective surface 311, and to reflect the light ray A to the second reflector 320 via the second reflective surface 312. Specifically, after receiving the light ray A passing through the first lens 210, the first reflective surface 311 can reflect the light ray A to the third reflective surface 313, the third reflective surface 313 can reflect the received light ray A to the second reflective surface 312, the second reflective surface 312 can reflect the received light ray A to the photosensitive chip 410, and the second reflector 320 can reflect the received light ray A to the photosensitive chip 410, thereby achieving imaging. That is to say, the first reflective surface 311 indirectly reflects the light ray A to the second reflector 320 through the third reflective surface 313.

[0062] This structure, by incorporating a third reflective surface 313, allows for greater flexibility in the placement of the first reflective surface 311 and the second reflective surface 312. This enables a larger angle between the first and second reflective surfaces 311 and 312, resulting in a larger angle between the first reflective surface 311 and the optical axis of the first lens 210, and vice versa. This avoids situations where the angles between both reflective surfaces 311 and 312 and the optical axis of the first lens 210 are too small, leading to an excessively large size of the first reflective element 310 in the optical axis direction of the first lens 210. Such an oversized size could negatively impact the size of the camera assembly in the optical axis direction, potentially affecting the layout of the electronic device. In other words, this structure helps reduce the thickness of the camera assembly, thereby minimizing its impact on the thickness of the electronic device and facilitating a thinner and lighter design.

[0063] Based on the camera component disclosed in the embodiments of this application, the embodiments of this application further disclose an electronic device, which includes a device housing and the camera component described in any of the above embodiments, wherein the camera component is at least partially disposed within the device housing.

[0064] Furthermore, the electronic device may also include a first circuit board, which may be disposed within the device housing. The circuit board may have a first clearance hole, and the camera assembly may be supported on a first side of the first circuit board. The first reflector 310 may extend through the first clearance hole to the first side of the first circuit board, thereby reducing the space occupied by the camera assembly in the stacking direction within the device housing and minimizing its impact on the thickness of the electronic device. Specifically, the stacking direction may be parallel to the optical axis of the first lens 210, the thickness direction of the electronic device may be parallel to the stacking direction, and the distribution direction of the first lens 210 and the first reflector 310 may be parallel to the optical axis of the first lens 210. In addition, the camera assembly may be connected to the first circuit board by means of adhesive bonding, snap-fitting, or other methods.
