Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to a camera module and electronic equipment. Background Technology

[0002] As a core component for image acquisition in electronic devices, camera modules are widely used in terminal products such as mobile phones and tablets. Autofocus is a key technology for ensuring image clarity and improving the shooting experience, enabling camera modules to quickly adapt to targets at different distances to obtain clear images.

[0003] In related technologies, camera modules typically adjust the relative distance between the lens and the image sensor by driving a focusing carrier to change the focal length of the optical image, thereby completing the autofocus operation. However, during the movement of the focusing carrier to perform the focusing operation, the focusing carrier is prone to problems such as deflection, tilting, or shaking, which causes the relative position of the lens and the image sensor to shift, resulting in a decrease in the focusing accuracy of the camera module and thus affecting the image quality of the camera module. Summary of the Invention

[0004] The purpose of this application is to provide a camera module and electronic device that can solve the problems of deflection, tilting or shaking of the focusing carrier in related technologies.

[0005] In a first aspect, embodiments of this application provide a camera module, which includes a first lens and a driving module. The driving module includes a focusing carrier, a first magnetic component, a second magnetic component, and a base. The focusing carrier is connected to the first lens and disposed within the base. The first magnetic component and the second magnetic component are both connected to the focusing carrier. The first magnetic component is used to drive the focusing carrier to move relative to the base. The first magnetic component and the second magnetic component are respectively located on opposite sides of the focusing carrier. The base is provided with a first limiting member and a second limiting member, which are located on opposite sides of the focusing carrier. The first limiting member is magnetically attracted to the first magnetic member, and the second limiting member is magnetically attracted to the second magnetic member.

[0006] Secondly, embodiments of this application also provide an electronic device, which includes a device body and the aforementioned camera module, wherein the camera module is disposed on the device body.

[0007] In this embodiment, a first limiting member and a second limiting member are provided inside the base, and the first limiting member and the second limiting member are respectively disposed on opposite sides of the focusing carrier. The first limiting member is magnetically attracted to the first magnetic member, and the second limiting member is magnetically attracted to the second magnetic member. With this arrangement, during the movement of the focusing carrier, there is a continuous magnetic attraction force on opposite sides of the focusing carrier, which can restrict the focusing carrier to avoid deflection, tilting, or shaking, and ensure the smooth movement of the focusing carrier. At the same time, the magnetic attraction forces on both sides restrain each other, which can make the friction force between the focusing carrier and the base evenly distributed, so as to avoid the problems of deflection, tilting, and shaking of the focusing carrier due to uneven force, further ensuring the smooth movement of the focusing carrier, thereby effectively improving the focusing accuracy of the camera module and improving the imaging quality of the camera module.

Detailed Implementation

[0010] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0011] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of 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 the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0012] The camera module and electronic device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0013] refer to Figures 1-16 The camera module provided in this application embodiment may include a first lens 100 and a drive module 200. The drive module 200 may include a focusing carrier 220, a first magnetic element 250, a second magnetic element 260, and a base 210. The focusing carrier 220 may be connected to the first lens 100 and may be disposed within the base 210. The first magnetic element 250 and the second magnetic element 260 may both be connected to the focusing carrier 220. The first magnetic element 250 may be used to drive the focusing carrier 220 to move relative to the base 210 to perform a focusing operation.

[0014] like Figure 6 As shown, the first magnetic element 250 and the second magnetic element 260 can be located on opposite sides of the focusing carrier 220, respectively. A first limiting element 270 and a second limiting element 280 can be provided inside the base 210. The first limiting element 270 and the second limiting element 280 can be located on opposite sides of the focusing carrier 220, respectively. The first limiting element 270 and the first magnetic element 250 can be magnetically attracted to each other, and the second limiting element 280 and the second magnetic element 260 can be magnetically attracted to each other.

[0015] In this embodiment, a first limiting member 270 and a second limiting member 280 are provided within the base 210, and are respectively positioned on opposite sides of the focusing carrier 220. The first limiting member 270 is magnetically attracted to the first magnetic member 250, and the second limiting member 280 is magnetically attracted to the second magnetic member 260. This arrangement ensures that during the movement of the focusing carrier 220, a continuous magnetic attraction force exists on opposite sides of the focusing carrier 220, which restricts the focusing carrier 220 and prevents it from deflecting, tilting, or wobbling, thus ensuring stable movement. Simultaneously, the mutual restraint of the magnetic attraction forces on both sides ensures a uniform distribution of friction between the focusing carrier 220 and the base 210, preventing deflection, tilting, or wobbling due to uneven force distribution, further guaranteeing stable movement of the focusing carrier 220. This effectively improves the focusing accuracy and imaging quality of the camera module.

[0016] In an optional embodiment, both the first limiting member 270 and the second limiting member 280 can be ferromagnetic structures. For example, both the first limiting member 270 and the second limiting member 280 can be iron sheets. This configuration, compared to having both the first limiting member 270 and the second limiting member 280 be magnetic, can, on the one hand, avoid magnetic field interference from the first limiting member 270 and the second limiting member 280 to the magnetic or electromagnetic components within the drive module 200, thus less likely to affect the movement of the focusing carrier 220 and the image stabilization carrier 230 described below; on the other hand, it can reduce costs.

[0017] Of course, both the first limiting member 270 and the second limiting member 280 can be magnetic.

[0018] In optional embodiments, such as Figure 4 As shown, the focusing carrier 220 may have a first corner 223 and a second corner 224. The line connecting the first corner 223 and the second corner 224 may pass through the central axis of the focusing carrier 220. The first limiting member 270 and the second limiting member 280 may be respectively positioned close to the first corner 223 and the second corner 224.

[0019] In this embodiment, since the line connecting the first corner 223 and the second corner 224 passes through the central axis of the focusing carrier 220, and the first limiting member 270 and the second limiting member 280 are respectively positioned close to the first corner 223 and the second corner 224, the center of the line connecting the two bearing surfaces that cooperate with the base 210 is close to or coincides with the central axis of the focusing carrier 220. That is, the bearing force center of the focusing carrier 220 is close to or coincides with the central axis of the focusing carrier 220. In this way, during the movement of the focusing carrier 220, the frictional force between the focusing carrier 220 and the base 210 can be approximately symmetrically distributed along the central axis, which can effectively avoid the problem of the focusing carrier 220 deflecting or tilting due to force offset. Simultaneously, this arrangement helps to ensure that the optical center of the first lens 100, the central axis of the focusing carrier 220, and the force center of the focusing carrier 220 coincide, effectively reducing the gravitational torque of the focusing carrier 220. This, in turn, effectively improves the vibration resistance of the focusing carrier 220, preventing deflection, tilting, and shaking during its movement. Furthermore, the reduction in gravitational torque allows for a reduction in the magnetic attraction force of the first magnetic component 250 and the second magnetic component 260. While maintaining the constraint effect, this reduces the friction between the focusing carrier 220 and the base 210. On one hand, this reduces the driving force required to move the focusing carrier 220, lowering the overall power consumption of the camera module and enabling longer battery life. On the other hand, it reduces wear on the focusing carrier 220 and the base 210, extending the lifespan of the camera module.

[0020] In other embodiments, the first limiting member 270 and the second limiting member 280 may not be located close to the first corner 223 and the second corner 224 respectively.

[0021] In an optional embodiment, the drive module 200 may further include a first slider 290 and a second slider 2110, wherein the first slider 290 and the second slider 2110 may both be arranged along the moving direction of the focusing carrier 220, such as... Figure 5 As shown, the focusing carrier 220 and the base 210 can be slidably engaged by the first sliding member 290 and the second sliding member 2110. This arrangement serves two purposes: firstly, the first sliding member 290 and the second sliding member 2110 can guide the movement of the focusing carrier 220, reducing the probability of the focusing carrier 220 shifting; secondly, it can reduce the friction between the focusing carrier 220 and the base 210, thereby reducing wear on both the base 210 and the focusing carrier 220 and extending their service life.

[0022] Of course, the drive module 200 may also exclude the first slider 290 and the second slider 2110.

[0023] The focusing carrier 220 has a first corner 223 and a second corner 224, and the line connecting the first corner 223 and the second corner 224 (e.g.) Figure 5 The dotted line shown passes through the central axis of the focusing carrier 220. The first sliding member 290 can be located at the first corner 223, and the second sliding member 2110 can be located at the second corner 224. This arrangement allows the first sliding member 290 and the second sliding member 2110 to form a diagonal layout symmetrical along the central axis of the focusing carrier 220. Since the bearing surface between the focusing carrier 220 and the base 210 is formed by the first sliding member 290 and the second sliding member 2110, the bearing surfaces between the focusing carrier 220 and the base 210 are diagonally symmetrical at 180°. This ensures that the frictional force between the focusing carrier 220 and the base 210 is diagonally symmetrically distributed along the central axis, guaranteeing the force balance of the focusing carrier 220.

[0024] In other embodiments, the first slider 290 may not be located at the first corner 223, and the second slider 2110 may not be located at the second corner 224.

[0025] In one alternative embodiment, such as Figure 6 As shown, at least one of the first sliding member 290 and the second sliding member 2110 may include a guide rod 2101, which can be arranged along the moving direction of the focusing carrier 220. This arrangement, since the guide rod 2101 is a one-piece rigid structure, effectively reduces the risk of detachment, improving the reliability of the first sliding member 290 and / or the second sliding member 2110. Furthermore, because the guide rod 2101 makes line or surface contact with the focusing carrier 220 and the base 210, it effectively disperses the contact pressure throughout the contact area, reducing contact pressure and preventing the formation of pits on the contact surfaces of the base 210 and the focusing carrier 220 with the guide rod 2101.

[0026] For example, both the first slider 290 and the second slider 2110 may include a guide rod 2101.

[0027] In another alternative embodiment, such as Figure 3 As shown, at least one of the first sliding member 290 and the second sliding member 2110 may include at least two first balls 2102, each first ball 2102 being distributed along the moving direction of the focusing carrier 220. This configuration allows the sliding friction between the focusing carrier 220 and the base 210 to be converted into rolling friction by the first balls 2102, which helps reduce the frictional resistance of the axial movement of the focusing carrier 220, reduces the driving force requirement of the drive module 200, helps reduce the power consumption of the camera module, and simultaneously improves the smoothness and response speed of the focusing movement of the focusing carrier 220.

[0028] For example, the first slider 290 and the second slider 2110 may each include at least two first balls 2102.

[0029] In an optional embodiment of this application, the drive module 200 may further include a stabilization carrier 230, such as Figure 4 , Figure 5 and Figure 7 As shown, the image stabilization carrier 230 can be located inside the focusing carrier 220 and can slide with the focusing carrier 220. The image stabilization carrier 230 can be connected to the first lens 100 so that the connection between the first lens 100 and the focusing carrier 220 can be achieved through the image stabilization carrier 230.

[0030] At least a portion of the second magnetic element 260 can be connected to the image stabilization carrier 230 and can be used to move the image stabilization carrier 230 relative to the focusing carrier 220 along a first direction. This configuration enables image stabilization of the first lens 100 in the first direction.

[0031] The drive module 200 may also include a third magnetic component 2120, such as Figure 4 As shown, the third magnetic component 2120 can be connected to the image stabilization carrier 230 and can be used to drive the image stabilization carrier 230 to move relative to the focusing carrier 220 in the second direction. This configuration enables image stabilization of the first lens 100 in the second direction.

[0032] The first direction, the second direction, and the moving direction of the focusing carrier 220 intersect each other. For example, the first direction, the second direction, and the moving direction of the focusing carrier 220 can be perpendicular to each other.

[0033] In this embodiment, by driving the image stabilization carrier 230 in the first and second directions respectively through the second magnetic element 260 and the third magnetic element 2120, the first lens 100 can achieve image stabilization compensation in at least two directions, so as to accurately compensate for the shaking in the first and second directions, so that the optical axis of the first lens 100 can always coincide with the central axis of the focusing carrier 220, which is beneficial to improving the imaging clarity of the camera module.

[0034] In other embodiments, the second magnetic element 260 may not be connected to the image stabilization carrier 230, and the second magnetic element 260 may not drive the image stabilization carrier 230 to move relative to the focusing carrier 220 in the first direction. For example, the second magnetic element 260 can only magnetically engage with the second limiting element 280. The drive module 200 may also not include the third magnetic element 2120.

[0035] In one optional embodiment, the second magnetic component 260 can be a stabilizing magnetic component 261. The stabilizing magnetic component 261 can be connected to the stabilizing carrier 230 and can be used to drive the stabilizing carrier 230 to move along the first direction. The stabilizing magnetic component 261 can magnetically engage with the second limiting component 280. This configuration allows the stabilizing magnetic component 261 to integrate the functions of magnetic limiting and stabilizing drive, reducing the number of magnetic components, simplifying the structure of the drive module 200, which is beneficial for reducing the size of the drive module 200, improving space utilization, and adapting to the miniaturization and thinning design requirements of the camera module.

[0036] In other embodiments, the second magnetic element 260 may not be the image stabilization magnetic element 261. For example, the second magnetic element 260 is not connected to the image stabilization carrier 230 and cannot drive the image stabilization carrier 230 to move along the first direction. The second magnetic element 260 is disposed on the focusing carrier 220 and can only be magnetically attracted to the second limiting element 280.

[0037] In another alternative embodiment, such as Figure 3 , Figure 4 and Figure 6 As shown, the second magnetic component 260 may include an image stabilization magnetic component 261 and a fourth magnetic component 262. The image stabilization magnetic component 261 may be connected to the image stabilization carrier 230 and may be used to drive the image stabilization carrier 230 to move along the first direction. The fourth magnetic component 262 may be connected to the focusing carrier 220 and may be magnetically attracted to the second limiting component 280.

[0038] In this configuration, the fourth magnetic component 262 only serves to magnetically engage with the second limiting component 280. Without the layout constraints of image stabilization drive, it can be positioned close to the second corner 224, according to the 180° diagonal symmetry requirement of the focusing carrier 220. This reduces the distance between the fourth magnetic component 262 and the second limiting component 280, and also helps to reduce the size of the fourth magnetic component 262. Simultaneously, the image stabilization magnetic component 261 only undertakes the driving function in the first direction of the image stabilization carrier 230. It does not need to accommodate the layout requirements of the second limiting component 280, which magnetically engages with the second magnetic component 260, and can be arranged according to the requirements of image stabilization drive.

[0039] In some embodiments, the drive module 200 may further include an image stabilization bracket 240, which may be disposed within the focusing carrier 220. The image stabilization carrier 230 and the image stabilization bracket 240 are slidably engaged in a first direction. By the relative movement of the image stabilization carrier 230 and the image stabilization bracket 240, image stabilization of the first lens 100 in the first direction can be achieved. The image stabilization bracket 240 and the focusing carrier 220 are slidably engaged in a second direction. By the relative movement of the image stabilization bracket 240 and the focusing carrier 220, image stabilization of the first lens 100 in the second direction can be achieved.

[0040] Optionally, the image stabilization carrier 230 and the image stabilization bracket 240 can be slidably engaged by at least one second ball bearing 2160, and the image stabilization bracket 240 and the focusing carrier 220 can be slidably engaged by at least one third ball bearing 2170.

[0041] For example, such as Figure 10 As shown, the image stabilization carrier 230 may be provided with a first guide groove 231, such as... Figure 11 As shown, the image stabilization bracket 240 may be provided with a second guide groove 241, and the first guide groove 231 and the second guide groove 241 are disposed opposite to each other. The first guide groove 231 and the second guide groove 241 may both extend along the first direction, and the second ball bearing 2160 is rotatably disposed in the first guide groove 231 and the second guide groove 241, so as to realize the sliding cooperation between the image stabilization carrier 230 and the image stabilization bracket 240.

[0042] In this embodiment, the image stabilization carrier 230 is provided with four first guide grooves 231, which can be located at the four corners of the image stabilization carrier 230 respectively. The image stabilization bracket 240 is provided with four second guide grooves 241, which can be located at the four corners of the image stabilization bracket 240 respectively. The second guide grooves 241 can be located on the side of the image stabilization bracket 240 facing the image stabilization carrier 230.

[0043] like Figure 11 As shown, a third guide groove 242 can be provided on the image stabilization bracket 240, such as... Figure 9 As shown, a fourth guide groove 222 may be provided on the focusing carrier 220, and a third guide groove 242 is disposed opposite to the fourth guide groove 222. At least one of the third guide groove 242 and the fourth guide groove 222 may extend along the second direction, and a third ball bearing 2170 is rotatably disposed in the third guide groove 242 and the fourth guide groove 222 to achieve sliding engagement between the image stabilization bracket 240 and the focusing carrier 220.

[0044] For example, the image stabilization bracket 240 may be provided with four third guide grooves 242, wherein at least two of the third guide grooves 242 may extend along the second direction, and the focusing carrier 220 may be provided with four fourth guide grooves 222, each of the fourth guide grooves 222 corresponding to one of the third guide grooves 242. This arrangement helps to improve the stability of the movement of the image stabilization carrier 230 and the image stabilization bracket 240.

[0045] Optionally, a groove 221 may be provided on the side wall of the focusing carrier 220, and the first magnetic element 250 is disposed in the groove 221. The opening of the groove 221 may be disposed away from the image stabilization carrier 230, that is, the opening of the groove 221 is disposed outward, so as to facilitate the installation and removal of the first magnetic element 250.

[0046] In an optional embodiment, to prevent the image stabilization carrier 230 from moving along the optical axis of the first lens 100, the drive module 200 may further include an image stabilization cover 2140, such as... Figure 5 As shown, the image stabilization cover 2140 can be connected to the focusing carrier 220. In the optical axis direction of the first lens 100, the image stabilization carrier 230 is respectively positioned and cooperates with the image stabilization cover 2140 and the focusing carrier 220.

[0047] In an optional embodiment, the drive module 200 may further include a drive component 2130, such as Figure 3 As shown, the drive assembly 2130 may include a first coil 2131, a second coil 2132, and a third coil 2133. The first coil 2131 may be opposite to the first magnetic element 250 and may be used to interact with the first magnetic element 250 to cause the first magnetic element 250 to drive the focusing carrier 220 to move, thereby achieving focusing operation. The second coil 2132 may be opposite to at least a portion of the second magnetic element 260 and may be used to interact with at least a portion of the second magnetic element 260 to cause at least a portion of the second magnetic element 260 to drive the image stabilization carrier 230 to move along a first direction, thereby achieving image stabilization operation of the first lens 100 in the first direction. The third coil 2133 may be opposite to the third magnetic element 2120 and may be used to interact with the third magnetic element 2120 to cause the third magnetic element 2120 to drive the image stabilization carrier 230 to move along a second direction, thereby achieving image stabilization operation of the first lens 100 in the second direction. This configuration allows the driving force required for focusing operation of the focusing carrier 220 and the driving force required for stabilization operation of the image stabilization carrier 230 in the first and second directions to be output independently, without limiting or interfering with each other. Furthermore, the first coil 2131, the second coil 2132, and the third coil 2133 are all independent functional units, and a failure in one of them will not affect the normal operation of the other two.

[0048] In other embodiments, the drive assembly 2130 may also include only one coil. When a first current is applied to the coil, the coil, in conjunction with the first magnetic element 250, generates a driving force along the moving direction of the focusing carrier 220, thereby moving the focusing carrier 220 to perform a focusing operation; when a second current is applied to the coil, the coil, in conjunction with the second magnetic element 260, generates a driving force along the first direction, thereby causing the image stabilization carrier 230 to perform image stabilization movement in the first direction; when a third current is applied to the coil, the coil, in conjunction with the third magnetic element 2120, generates a driving force along the second direction, thereby causing the image stabilization carrier 230 to perform image stabilization movement in the second direction.

[0049] In optional embodiments, such as Figure 3 As shown, the drive assembly 2130 may also include a circuit board 2134.

[0050] In one way, such as Figure 3 As shown, the first coil 2131, the second coil 2132 and the third coil 2133 can all be separately set from the circuit board 2134 and electrically connected to the circuit board 2134 respectively.

[0051] In this embodiment, since the first coil 2131, the second coil 2132, and the third coil 2133 generate heat during operation, and the electronic components on the circuit board 2134 also generate heat during operation, the first coil 2131, the second coil 2132, and the third coil 2133 are separately arranged from the circuit board 2134. This allows the first coil 2131, the second coil 2132, the third coil 2133, and the circuit board 2134 to form independent units, which do not affect each other and facilitate rapid heat dissipation for each component. Furthermore, these components can be independently assembled and disassembled for independent debugging and maintenance. In a further optional embodiment, the first coil 2131, the second coil 2132, and the third coil 2133 can all be spaced apart from the circuit board 2134, thereby further improving heat dissipation performance. Of course, the first coil 2131, the second coil 2132, and the third coil 2133 can also be connected to the circuit board 2134 by means of bonding, soldering, or other methods.

[0052] In another way, such as Figure 12 As shown, the first coil 2131, the second coil 2132, and the third coil 2133 can all be integrated into the circuit board 2134. This configuration allows for the seamless integration of the first coil 2131, the second coil 2132, and the third coil 2133 with the circuit board 2134, eliminating the need for additional space for their arrangement. This reduces the size of the camera module and promotes miniaturization of electronic devices. Furthermore, the first coil 2131, the second coil 2132, the third coil 2133, and the circuit board 2134 can be assembled as a single unit, effectively simplifying the assembly and disassembly process, shortening assembly time, and reducing manufacturing costs.

[0053] In some embodiments, the drive module 200 may further include a housing 2150, which may cover at least a portion of the focusing carrier 220, the first magnetic element 250, the second magnetic element 260, the drive assembly 2130, and the base 210, and the housing 2150 may be connected to the base 210 to protect and shield the components such as the focusing carrier 220, the first magnetic element 250, the second magnetic element 260, the drive assembly 2130, and the base 210.

[0054] In optional embodiments, such as Figure 1As shown, the camera module may further include a second lens 300, a portion of which can extend into the housing 2150 of the drive module 200, and the second lens 300 can be connected to the housing 2150. The optical axis of the first lens 100 can coincide with the optical axis of the second lens 300. This arrangement allows for the superposition of optical focal lengths, enabling the camera module to adjust to more focal lengths.

[0055] In optional embodiments, such as Figure 1 As shown, the camera module may also include a periscope assembly 400 and a photosensitive element 500. The periscope assembly 400 is connected to the base 210, and the light inlet of the periscope assembly 400 is opposite to the light outlet of the base 210. The photosensitive element 500 is opposite to the light outlet of the periscope assembly 400. The periscope assembly 400 can reflect the light received through its own light inlet and then emit it from its own light outlet to the photosensitive element 500. With this configuration, the periscope assembly 400 can achieve the redirection and multiple reflections of the light path, which can effectively extend the light path length and increase the optical focal length, enabling telephoto shooting by the camera module and improving the user's shooting experience.

[0056] In other embodiments, the camera module may also exclude the periscope assembly 400, and the photosensitive element 500 may be directly opposite the light outlet of the base 210.

[0057] Optionally, such as Figure 14 As shown, the periscope assembly 400 may include a prism 410, which may be provided with a first reflective surface 411. The first reflective surface 411 is an inclined surface, and in the moving direction of the focusing carrier 220, the orthographic projection of the first reflective surface 411 covers the light outlet of the base 210.

[0058] In this embodiment, the first reflective surface 411 is an inclined surface, which can convert the propagation of light from the optical axis of the first lens 100 to other directions, thereby increasing the optical path length of the light. Furthermore, the orthographic projection of the first reflective surface 411 covers the light outlet of the base 210, so that all the light emitted from the light outlet of the base 210 falls on the first reflective surface 411, enabling the first reflective surface 411 to reflect all the light, which can effectively increase the amount of light entering the photosensitive element 500 and improve the imaging quality of the camera module.

[0059] Of course, the prism 410 may also omit the first reflecting surface 411.

[0060] For example, the periscope assembly 400 also includes a reflective film covering the prism 410 to create a reflective environment inside the prism 410. Specifically, the reflective film can make the prism 410 form a first reflective surface 411, and the reflective film can also make the prism 410 form a second reflective surface and a third reflective surface. The second reflective surface can be located on the side of the prism 410 closer to the driving module 200, and the third reflective surface can be located on the side of the prism 410 away from the driving module 200. After being reflected by the first reflective surface 411, light can be reflected by the second and third reflective surfaces in sequence until the light reaches the light outlet of the periscope assembly 400 and is emitted from the light outlet of the periscope assembly 400. Here, the reflective film is provided with a first clearance opening and a second clearance opening. The first clearance opening is arranged opposite to the light outlet of the base 210 to form the light inlet of the periscope assembly 400, and the second clearance opening is arranged opposite to the photosensitive element 500 to form the light outlet of the periscope assembly 400.

[0061] In one alternative approach, such as Figure 14 and Figure 15 As shown, the light outlets of the first reflective surface 411 and the periscope assembly 400 can be located on opposite sides of the prism 410. This arrangement allows the photosensitive element 500 to be placed on the side of the periscope assembly 400 away from the first reflective surface 411, thereby increasing the length of the optical path.

[0062] In one embodiment, the light-emitting port of the periscope assembly 400 can be tilted, and, as... Figure 14 As shown, the tilt direction of the first reflective surface 411 can be opposite to the tilt direction of the light outlet of the periscope assembly 400. This arrangement allows the tilt direction of the photosensitive element 500 to be opposite to the tilt direction of the first reflective surface 411, so as to effectively utilize the space below the end of the periscope assembly 400 to arrange the photosensitive element 500.

[0063] In another embodiment, the light-emitting port of the periscope assembly 400 can be tilted, and, as... Figure 15 As shown, the tilt direction of the first reflective surface 411 can be the same as the tilt direction of the light outlet of the periscope assembly 400. In this way, the tilt direction of the photosensitive element 500 can be the same as the tilt direction of the first reflective surface 411, so as to effectively utilize the space above the end of the periscope assembly 400 to arrange the photosensitive element 500.

[0064] Furthermore, by lengthening the prism 410, light can be reflected one or more times, thereby increasing the optical path length of the periscope assembly 400 and achieving a greater telephoto effect.

[0065] In another alternative approach, such as Figure 16As shown, the light inlet and light outlet of the periscope assembly 400 are located on the same side of the prism 410. This arrangement allows the photosensitive element 500 and the driving module 200 to be placed on the same side of the periscope assembly 400, making full use of the unused space on the side of the periscope assembly 400 closest to the driving module 200. This helps to reduce the overall space occupied by the camera module and the length of the camera module in the optical axis direction of the first lens 100, thus facilitating the adaptation to the design requirements of thinner and lighter electronic devices.

[0066] In this embodiment of the application, when assembling the camera module, such as Figure 13 As shown, the first step is to assemble the drive module 200 and the second lens 300 to form the first component 600; the second step is to assemble the first component 600 and the first lens 100. Specifically, the first component 600 is inverted on a fixture, and the first lens 100 is fixed to the image stabilization carrier 230 of the drive module 200 by AA dispensing process (i.e., a combination process of active alignment and special adhesive dispensing and curing), so that the first component 600 and the first lens 100 are assembled to form the second component 700; the third step is to assemble the second component 700, the periscope component 400 and the photosensitive element 500, and fix the second component 700, the periscope component 400 and the photosensitive element 500 by dispensing process to form the camera module.

[0067] In this embodiment, the magnetic attraction between the first magnetic element 250 and the first limiting element 270, and the magnetic attraction between the second magnetic element 260 and the second limiting element 280, can effectively improve the stability of the focusing carrier 220 and solve the problem of vibration interference to the focusing carrier 220 when the user is walking. The periscope component 400 enables the camera module to achieve super telephoto shooting function, which can effectively enhance the user's photography experience.
