Description

Technical Field

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

[0002] With the rapid development of electronic devices, retractable camera modules have become the mainstream. The retractable cameras used in the camera modules of electronic devices are mainly driven by a drive device, and the design of the drive device determines the accuracy and reliability of the retractable camera's movement.

[0003] Current drive devices generally include a motor and gears. The motor is connected to the lens barrel through the gears. In order to move the lens, a mating protrusion can be set on one lens barrel and a sliding groove can be set on the other lens barrel. The mating protrusion and the sliding groove can serve as a transmission structure. When one lens barrel rotates, the mating protrusion slides into the sliding groove, thereby realizing the relative movement between the two lens barrels and ultimately realizing the movement of the lens.

[0004] However, when the telescopic camera is in the extended state and the electronic device is dropped, the transmission structure inside the telescopic camera will be subjected to a large impact load, that is, a large impact will be generated between the mating protrusion and the slide, which makes the mating protrusion and the slide more prone to failure. Therefore, the reliability of this type of camera module is poor. Summary of the Invention

[0005] The purpose of this application is to provide a camera module and electronic device that can solve the problem of poor reliability of camera modules involved in related technologies.

[0006] In a first aspect, embodiments of this application provide a camera module, including a base, a photosensitive chip, a first lens barrel, a first lens, a driving mechanism, and a support member;

[0007] The photosensitive chip is disposed on the base, the first lens barrel is sleeved on the base, the first lens barrel is provided with the first lens, the driving mechanism is connected to the first lens barrel, and the driving mechanism drives the first lens barrel to move along a first direction, the first direction being the direction of moving closer to or away from the photosensitive chip;

[0008] The support member is movably disposed on the base and can move between a first position and a second position. When the support member is in the first position, the support member avoids the first lens barrel so that the first lens barrel can move along the first direction. When the support member is in the second position, the first lens barrel extends relative to the base, and at least a portion of the support member is located between the first lens barrel and the photosensitive chip to support the first lens barrel.

[0009] Secondly, embodiments of this application provide an electronic device, including the camera module described above.

[0010] In this embodiment, since the first lens is mounted on the first lens barrel, the driving mechanism can simultaneously drive the first lens barrel and the first lens to move in a direction closer to or further away from the photosensitive chip. The support member can move between a first position and a second position on the base. When the support member is in the first position, it can avoid the first lens barrel, allowing the first lens barrel to move in a direction closer to or further away from the photosensitive chip. When the support member is in the second position, the first lens barrel extends relative to the base. At this time, at least a portion of the support member is located between the first lens barrel and the photosensitive chip to support the first lens barrel. Therefore, when the electronic device is dropped or otherwise impacted, the first lens barrel can transmit the impact to the support member, meaning the support member can share some of the energy generated by the impact. This minimizes damage to the first lens barrel and the transmission structure inside the camera module, thereby improving the reliability of the camera module. Attached Figure Description

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.

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.

[0034] The camera module disclosed in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0035] Please refer to Figures 1-11 This application discloses a camera module, which includes a base 100, a photosensitive chip 200, a first lens barrel 300, a first lens 700, a drive mechanism 400, and a support member 500.

[0036] The base 100 serves as the foundation of the camera module, providing a mounting base for other components, such as the image sensor 200. The image sensor 200, mounted on the base 100, is one of the main components enabling the camera module to take pictures. A first lens barrel 300 is retractably mounted on the camera module to achieve zoom functionality and meet various shooting needs. Specifically, the first lens barrel 300 is fitted onto the base 100 and includes a first lens 700. When the first lens barrel 300 retracts relative to the base 100, it also retracts relative to the base 100. The number of first lenses 700 can be one or more. Furthermore, the camera module may include a second lens, which can be stationary relative to the image sensor 200 or retract relative to it, further optimizing the zoom effect.

[0037] The above-mentioned extension and retraction process can be realized by the drive mechanism 400. Specifically, the drive mechanism 400 is connected to the first lens barrel 300. The drive mechanism 400 can drive the first lens barrel 300 to move along a first direction, which is the direction of moving closer to or away from the photosensitive chip 200. When the drive mechanism 400 drives the first lens barrel 300 to move along the direction of moving away from or closer to the photosensitive chip 200, the zoom shooting requirements of the camera module can be realized.

[0038] The support member 500 has a supporting function. Specifically, the support member 500 is movably disposed on the base 100. The support member 500 can move between a first position and a second position. When the support member 500 is in the first position, the support member 500 can avoid the first lens barrel 300 so that the first lens barrel 300 can move along the first direction. That is, at this time, the support member 500 does not affect the extension and retraction of the first lens barrel 300 relative to the base 100. When the support member 500 is in the second position, the first lens barrel 300 extends relative to the base 100 so that at least a part of the support member 500 is located between the first lens barrel 300 and the photosensitive chip 200 to support the first lens barrel 300. That is, in the direction of the first lens 700 and the photosensitive chip 200, the orthographic projection of the first lens barrel 300 overlaps with the orthographic projection of the support member 500.

[0039] If an electronic device equipped with a camera module falls, the first lens barrel 300 will collide with the object, causing the first lens barrel 300 to generate a force toward the photosensitive chip 200. Since the support member 500 can support the first lens barrel 300, this force can be transferred to the support member 500 through the first lens barrel 300 to prevent the first lens barrel 300 from applying this force to the drive mechanism 400. In other words, the support member 500 can share some of the energy generated by the impact on the first lens barrel 300, thereby reducing the collision energy received by the transmission structure of the drive mechanism 400, that is, reducing the collision energy received by the transmission mechanism 420, the first mating protrusion 610 and the second mating protrusion 310 as described later.

[0040] In this embodiment, since the first lens 700 is disposed on the first lens barrel 300, the driving mechanism 400 can simultaneously drive the first lens barrel 300 and the first lens 700 to move in a direction closer to or further away from the photosensitive chip 200. The support member 500 can move between a first position and a second position on the base 100. When the support member 500 is in the first position, the support member 500 can avoid the first lens barrel 300 so that the first lens barrel 300 can move in a direction closer to or further away from the photosensitive chip 200. When the support member 500 is in the second position, the first lens barrel 300 extends relative to the base 100. At this time, at least a portion of the support member 500 is located between the first lens barrel 300 and the photosensitive chip 200 to support the first lens barrel 300. Therefore, when an electronic device is dropped or otherwise impacted, the first lens barrel 300 can transmit the impact to the support member 500. In other words, the support member 500 can share some of the energy generated by the impact, which makes the damage to the first lens barrel 300 and the transmission structure inside the camera module less, thereby improving the reliability of the camera module.

[0041] Optionally, the base 100 includes a fixed sleeve 110, the first lens barrel 300 is sleeved inside the fixed sleeve 110, and the support member 500 is telescopically disposed on the inner wall of the fixed sleeve 110 so that the support member 500 can move between a first position and a second position, and the telescopic direction of the support member 500 can be perpendicular to the first direction. This allows the support member 500 to support the first lens barrel 300 when it extends relative to the base 100. However, since the support member 500 is disposed on the inner wall of the fixed sleeve 110, space needs to be reserved between the fixed sleeve 110 and the first lens barrel 300 for installing the support member 500. This increases the space occupied by the fixed sleeve 110, the support member 500 and the first lens barrel 300 in the camera module, which is not conducive to the setting of other components.

[0042] Therefore, in another embodiment, the fixed sleeve 110 is provided with a clearance hole 111 that passes through the fixed sleeve 110, that is, the fixed sleeve 110 is provided with a through hole facing the first lens barrel 300. At least a portion of the support member 500 is disposed in the clearance hole 111. The support member 500 can move between a first position and a second position along the through direction of the clearance hole 111. At this time, since at least a portion of the support member 500 is disposed in the clearance hole 111, the space that needs to be reserved between the fixed sleeve 110 and the first lens barrel 300 for setting the support member 500 is small, or even no space needs to be reserved for setting the support member 500. This makes the space occupied by the fixed sleeve 110, the support member 500 and the first lens barrel 300 of the camera module smaller, which is conducive to the installation of other components. At the same time, the support member 500 can be set long enough to improve the support effect on the first lens barrel 300.

[0043] Optionally, the drive mechanism 400 may include a drive disk 430 and at least two drive sources 410. One drive source 410 is connected to the drive disk 430, which is arranged around the fixed sleeve 110. The support member 500 is connected to the drive disk 430, meaning that the drive source 410 can drive the drive disk 430 to move, so that the drive disk 430 can drive the support member 500 to move. Specifically, the drive disk 430 can drive the support member 500 to move between a first position and a second position. The other drive source 410 is connected to the first lens barrel 300 to drive the first lens barrel 300 to move. Specifically, under the driving action of the drive source 410, the first lens barrel 300 can move along a first direction.

[0044] However, this arrangement of at least two drive sources 410 may increase the overall size of the camera module and make it difficult to ensure that at least two drive sources 410 simultaneously drive the first lens barrel 300 and the drive disk 430 to move, which may result in the support member 500 failing to support the first lens barrel 300 in a timely and accurate manner.

[0045] To avoid the aforementioned problems, in another embodiment, the driving mechanism 400 includes a transmission mechanism 420 and a driving source 410. The driving source 410 is connected to the driving disk 430 and the first lens barrel 300 respectively through the transmission mechanism 420. That is, the driving source 410 can simultaneously drive the first lens barrel 300 and the driving disk 430 to move through the transmission mechanism 420, thereby enabling the support member 500 and the first lens barrel 300 to move simultaneously. Therefore, in this configuration, by simultaneously driving the support member 500 and the first lens barrel 300 to move through the same driving source 410, the problem of a large overall size of the camera module can be avoided. At the same time, it can also ensure that the support member 500 supports the first lens barrel 300 in a timely and accurate manner. Optionally, the driving source 410 can be a component with driving function, such as a motor.

[0046] Optionally, the transmission mechanism 420 can be a gear transmission mechanism, that is, the transmission mechanism 420 includes a first gear 421, a second gear 422 and a third gear 423. A worm gear 411 is provided on the output shaft of the drive source 410. The worm gear 411 meshes with the first gear 421. The first gear 421 also meshes with the second gear 422 and the third gear 423. The second gear 422 drives the first lens barrel 300 to move in a direction close to or away from the photosensitive chip 200. The third gear 423 meshes with the first drive tooth 432 of the drive disk 430 to drive the drive disk 430 to move. In turn, the drive disk 430 drives the support member 500 to move between the first position and the second position. This method of transmission through a gear mechanism has good transmission stability and reliability.

[0047] In one embodiment, the support member 500 can be rotatably connected to the drive disk 430. That is, during the process of the drive source 410 driving the drive disk 430 to rotate, the clearance hole 111 can be set to be relatively large so that the support member 500 can move relative to the clearance hole 111. The drive disk 430 can apply a force to the support member 500, that is, push or pull the support member 500 so that the support member 500 can move between a first position and a second position relative to the clearance hole 111.

[0048] In another embodiment, the support member 500 is slidably engaged with the drive disk 430. Specifically, the support member 500 includes a first support portion 510 and a first protrusion 520, which are connected. At least a portion of the first support portion 510 is disposed within the clearance hole 111, and the first protrusion 520 is slidably engaged with the slide groove 431. The drive disk 430 drives the first protrusion 520 to slide within the slide groove 431, thereby enabling the first protrusion 520 to drive the first support portion 510 to move within the clearance hole 111. In this configuration, the sliding engagement of the first protrusion 520 with the slide groove 431 results in a larger contact area between the drive disk 430 and the support member 500, thus enabling the drive disk 430 to drive the support member 500 to move within the clearance hole 111 more stably and reliably. Meanwhile, when using a sliding fit, the support member 500 can move between a first position and a second position relative to the clearance hole 111. The clearance hole 111 can be set to be relatively small, thereby improving the structural strength of the fixed sleeve 110 and providing guidance for the movement of the support member 500, so that the support member 500 can move more stably.

[0049] Optionally, the shape of the slide groove 431 can be straight, that is, the distance between different positions of the slide groove 431 and the center line of the first lens 700 is uniform and continuously changing. Since the driving source 410 can drive the support member 500 and the first lens barrel 300 to move at the same time, that is, the starting time and stopping time of the support member 500 and the first lens barrel 300 are the same. However, since the support member 500 needs to move for a long time in the straight slide groove 431 to reach its position, if the camera module falls during this movement, the support member 500 will not be able to support the first lens barrel 300 at this time, that is, the support member 500 cannot play a supporting role at this time.

[0050] To enable the support member 500 to function quickly, in another embodiment, the slide groove 431 is bent. Specifically, the slide groove 431 includes a first groove segment 4311 and a second groove segment 4312 that are connected. The first groove segment 4311 is bent relative to the second groove segment 4312. When the first protrusion 520 engages with the first groove segment 4311, the support member 500 moves along a second direction. This second direction can be a direction that approaches or moves away from the center line of the first lens 700. That is, when the first protrusion 520 slides within the first groove segment 4311, the support member 500 can move closer to or further away from the center line of the first lens 700. Optionally, the first groove segment 4311 can be a straight groove segment, and the distance between its different positions and the center line of the first lens 700 is uniformly and continuously varied.

[0051] When the first protrusion 520 engages with the second groove 4312, at least a portion of the support member 500 is located between the first lens barrel 300 and the photosensitive chip 200 to support the first lens barrel 300. That is, once the first protrusion 520 engages with the second groove 4312, at least a portion of the support member 500 can support the first lens barrel 300, allowing the support member 500 to perform its supporting function. Therefore, this arrangement allows the support member 500 to move into position more quickly to support the first lens barrel 300. Optionally, the second groove 4312 can be an arc-shaped groove, with the center of its circumference coinciding with the rotation center of the drive disk 430. When the first protrusion 520 engages with the second groove 4312, the support member 500 no longer moves but remains in the position supporting the first lens barrel 300.

[0052] Optionally, the camera module can achieve zoom shooting by simply extending and retracting the first lens barrel 300, but in this case, the zoom range of the camera module is always limited. Therefore, to expand the zoom range, in another embodiment, the camera module also includes a second lens barrel 600, with the first lens barrel 300 sleeved within the second lens barrel 600. The second lens barrel 600 and the fixing sleeve 110 are provided with a first mating protrusion 610 and a first spiral guide groove 114, respectively. Optionally, the second lens barrel 600 is provided with the first mating protrusion 610, and the fixing sleeve 110 is provided with the first spiral guide groove 114, allowing the first mating protrusion 610 to move along the first spiral guide groove 114.

[0053] Since the drive mechanism 400 is connected to the second lens barrel 600 through the transmission mechanism 420, the drive mechanism 400 can drive the transmission mechanism 420 to move the second lens barrel 600. That is, the second lens barrel 600 can be driven by the drive mechanism 400. Specifically, the second lens barrel 600 is provided with a second drive tooth 640, which meshes with the second gear 422 of the transmission mechanism 420. The second gear 422 drives the second lens barrel 600 to rotate through the second drive tooth 640, so that the first mating protrusion 610 of the second lens barrel 600 can slide in the first spiral guide groove 114. That is, the second lens barrel 600 can move along a first direction under the cooperation of the first mating protrusion 610 and the first spiral guide groove 114. The first direction can be the direction that is closer to or farther away from the photosensitive chip 200.

[0054] With the support member 500 in the second position, both the first lens barrel 300 and the second lens barrel 600 extend relative to the base 100, that is, both the first lens barrel 300 and the second lens barrel 600 are far away from the photosensitive chip 200, so as to expand the zoom range of the camera module. At this time, at least a part of the support member 500 is located between the second lens barrel 600 and the photosensitive chip 200, so as to support the first lens barrel 300 and the second lens barrel 600 at the same time, so as to avoid the first mating protrusion 610 and the first spiral guide groove 114 being subjected to a large impact force when the electronic device is dropped, thus preventing failure.

[0055] In one embodiment, to drive the first lens barrel 300 to extend or retract relative to the second lens barrel 600, a driving magnet can be provided on the second lens barrel 600 and a driving coil can be provided on the first lens barrel 300. After the driving coil is energized, the first lens barrel 300 is driven to extend or retract relative to the second lens barrel 600 under the action of the driving magnet.

[0056] In another embodiment, one of the second lens barrel 600 and the first lens barrel 300 is provided with a second mating protrusion 310, and the other is provided with a second helical guide groove 620. Optionally, the first lens barrel 300 is provided with the second mating protrusion 310, and the second lens barrel 600 is provided with the second helical guide groove 620. The second mating protrusion 310 and the second helical guide groove 620 cooperate to allow the second lens barrel 600 to drive the first lens barrel 300 to move along a first direction, which can be a direction closer to or farther from the photosensitive chip 200. This method of guiding and cooperating the second mating protrusion 310 and the second helical guide groove 620 to extend and retract the first lens barrel 300 relative to the second lens barrel 600 has good extension and retraction stability and reliability.

[0057] Optionally, the camera module also includes a guide cylinder 800, which is sleeved inside the second lens barrel 600. The guide cylinder 800 is fixed relative to the second lens barrel 600 in a first direction, meaning that the second lens barrel 600 can drive the guide cylinder 800 to move in a direction closer to or further away from the photosensitive chip 200. The guide cylinder 800 is provided with a first sliding groove 810, the extension direction of which is parallel to the first direction. A second mating protrusion 310 can be fixedly connected to the lens barrel body of the first lens barrel 300. One end of the second mating protrusion 310 is slidably engaged with the second spiral guide groove 620, and the other end is slidably engaged with the first sliding groove 810. When the second lens barrel 600 moves in a direction closer to or further away from the photosensitive chip 200, the second mating protrusion 310 slides in the second spiral guide groove 620 and the first sliding groove 810 to drive the first lens barrel 300 to extend or retract relative to the second lens barrel 600.

[0058] Optionally, the guide cylinder 800 is slidably disposed within the fixed sleeve 110. Specifically, the guide cylinder 800 is provided with a second protrusion 820, and the fixed sleeve 110 is also provided with a third sliding groove 115. The extension direction of the third sliding groove 115 is parallel to the first direction. When the second lens barrel 600 drives the guide cylinder 800 to extend or retract relative to the base 100, the second protrusion 820 and the third sliding groove 115 slide in cooperation, so that the guide cylinder 800 moves along the extension direction of the third sliding groove 115.

[0059] Optionally, the second lens barrel 600 can drive the guide cylinder 800 to move along the first direction. Specifically, the guide cylinder 800 is provided with a third spiral guide groove 830, the second lens barrel 600 is provided with a second sliding groove 650, and the camera module also includes a drive column. The extension direction of the second sliding groove 650 is parallel to the first direction. One end of the drive column is slidably disposed in the third spiral guide groove 830, and the other end is slidably disposed in the second sliding groove 650. This allows the second lens barrel 600 to drive the guide cylinder 800 to move along the first direction when the second lens barrel 600 moves. At this time, the support member 500 supports the second lens barrel 600 and the first lens barrel 300 by supporting the guide cylinder 800.

[0060] Optionally, to prevent the drive column from sliding out of the second slide groove 650, a blocking part 630 is also provided on the second lens barrel 600. The blocking part 630 can prevent the drive column from sliding out of the second slide groove 650, so as to ensure the stability of the second lens barrel 600 driving the guide cylinder 800 to move.

[0061] Optionally, when a portion of the support member 500 passes through the clearance hole 111 into the interior of the fixing sleeve 110 to achieve the supporting function, another portion of the support member 500 may be exposed outside the fixing sleeve 110, that is, at least a portion of the support member 500 is at risk of being exposed.

[0062] To avoid the aforementioned risks and protect the support member 500, in another embodiment, the fixing sleeve 110 includes a sleeve body 112 and a mounting portion 113. The mounting portion 113 protrudes from the outer peripheral surface of the sleeve body 112 and is connected to the clearance hole 111. At least a portion of the support member 500 is disposed on the mounting portion 113. In this arrangement, the mounting portion 113 can protect the support member 500. At the same time, since the mounting portion 113 protrudes from the sleeve body 112, the support member 500 can move a longer distance within the clearance hole 111. Therefore, the mounting portion 113 can also play a certain guiding role, which allows the support member 500 to move more stably between the first position and the second position.

[0063] Optionally, the number of support members 500 can be one, but the supporting force provided by one support member 500 is relatively small. Therefore, in another embodiment, the number of support members 500 is at least two, and each support member 500 is evenly and spaced apart in the direction surrounding the center line of the first lens 700, so that the first lens barrel 300 and the second lens barrel 600 can be subjected to a more uniform supporting force, and the supporting capacity of multiple support members 500 for the first lens barrel 300 and the second lens barrel 600 is further improved, thereby improving the protection of the transmission mechanism 420, the first mating protrusion 610 and the first spiral guide groove 114 and the second mating protrusion 310 and the second spiral guide groove 620, thereby effectively improving the mechanical reliability of the entire camera module, extending its service life, and improving the user experience.

[0064] Meanwhile, this application places the support 500 on the fixed sleeve 110, which utilizes the design space of the camera module itself while ensuring the compactness of the internal structure of the camera module.

[0065] Optionally, the camera module also includes a flexible circuit board 900, which is electrically connected to the circuit board of the electronic device to provide operating current to components such as the photosensitive chip 200 of the camera module, thereby ensuring the normal operation of the camera module. Optionally, when the driving source 410 described above is a motor or other electrically driven component, the flexible circuit board 900 can provide operating current to the driving source 410 to enable the driving source 410 to perform its driving function.

[0066] Optionally, this application also discloses an electronic device, which includes the camera module described above.

[0067] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
