When the camera module shakes, the lens is prone to collision with the motor, which can produce abnormal noise and reduce the user experience. Furthermore, the collision between the two can easily damage the lens or the motor. Utility Model Content

[0018] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0019] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0020] It is understood that the camera module 100 provided in this application embodiment can be applied to electronic devices with camera functions, including but not limited to mobile phones, tablets, desktop computers and laptops. The camera module 100 can include modules with telephoto functions such as horizontal camera modules, vertical camera modules or telephoto periscope camera modules. No limitation is made here. This application embodiment takes the camera module 100 as a telephoto periscope camera module as an example for illustration.

[0021] The following is in conjunction with the appendix Figure 1-10 This application describes a camera module 100 according to some embodiments.

[0022] like Figure 1 As shown, the camera module 100 according to an embodiment of this application includes a motor 10 and a lens 20.

[0023] The lens 20 is movably connected to the motor 10 along the Z-axis of the optical axis. This allows for focal length adjustment via movement of the lens 20 along the Z-axis, thus facilitating the focusing function of the camera module 100.

[0024] For example, a focusing component may be provided inside the motor 10. The focusing component may include a focusing coil 50 and a focusing magnet. The focusing magnet may be provided on the lens 20. The focusing coil 50 is provided inside the motor 10. After the focusing coil 50 is energized, the focusing coil 50 will drive the focusing magnet to move the lens 20 in the direction Z of the optical axis to realize the focusing function of the camera module 100.

[0025] In some implementations, lens 20 includes a lens and a bracket, with the lens mounted on the bracket and the bracket having a mounting position for mounting a focusing magnet.

[0026] It is understood that the lens 20 of this application is an integrated lens 20, that is, the lens can be embedded in the bracket and the outer side of the bracket is provided with a mounting position for mounting the focusing magnet. The mounting position can be a groove or a flat area for bonding the focusing magnet, which is not limited here. In this way, when the motor 10 is provided with a focusing coil 50, the focusing coil 50 can drive the focusing magnet to directly drive the lens 20 to move along the optical axis Z to achieve focusing. In this way, the camera module 100 of this application does not need to be provided with a separate focusing carrier, so as to simplify its installation steps and improve production efficiency. At the same time, the focusing magnet can be directly mounted to the lens 20, which makes the arrangement of the lens 20 and the focusing magnet more compact. In particular, the bracket replaces the function of the lens barrel, so that the lens 20 of this application can eliminate the lens barrel, thereby reducing the radial dimension of the lens 20 and facilitating the miniaturization design of the lens 20.

[0027] like Figure 1 and Figure 2 As shown, the camera module 100 also includes a locking component 30.

[0028] The locking component 30 is connected to the motor 10, and the locking component 30 has a first state and a second state. In the first state, the locking component 30 and the lens 20 are unlocked in the direction Z of the optical axis. In the second state, the locking component 30 and the lens 20 are locked in the direction Z of the optical axis.

[0029] It is understandable that in order to achieve the telephoto function, the camera module 100 requires the lens 20 to have a large travel distance in the Z direction of the optical axis. If the travel distance of the lens 20 in the Z direction of the optical axis is increased, the risk of the lens 20 shaking in the Z direction perpendicular to the optical axis will increase. When the camera module 100 shakes, the lens 20 is prone to collide with the motor 10, producing abnormal noise, which reduces the user experience. Moreover, the collision between the two can easily damage the lens 20 or the motor 10, thereby reducing the service life of the camera module 100.

[0030] Therefore, in this application, a locking component 30 is provided. In the first state, the locking component 30 and the lens 20 are unlocked and engaged in the direction Z of the optical axis. In the second state, the locking component 30 and the lens 20 are locked and engaged in the direction Z of the optical axis.

[0031] Thus, when the lens 20 needs to move in the Z-direction of the optical axis to achieve the focusing function, the locking component 30 can be controlled to be in the first state, that is, the locking component 30 and the lens 20 are unlocked and engaged, so that the camera module 100 can achieve telephoto movement. When the focusing function of the lens 20 is not needed, the locking component 30 and the lens 20 can be controlled to lock in the Z-direction of the optical axis, so that the lens 20 is locked relative to the motor 10 in the Z-direction of the optical axis. This reduces the risk of the lens 20 shaking relative to the motor 10 in the Z-direction of the optical axis, thereby reducing impact noise and improving the user experience. At the same time, it can reduce the damage to the lens 20 or the motor 10 caused by the impact between the lens 20 and the motor 10, which helps to extend the service life of the camera module 100.

[0032] In some implementations, the locking component 30 can be set inside the motor 10 to achieve integrated setting of the motor 10 and the locking component 30. This helps to reduce the impact of the setting of the locking component 30 on the overall size of the camera module 100. At the same time, it helps to provide a certain degree of protection for the locking component 30 through the motor 10.

[0033] In some embodiments, such as Figure 3 As shown, the locking assembly 30 includes a latch 31 and a snap fastener 32. The latch 31 is movably connected to the motor 10, and the snap fastener 32 is located on the lens 20. In a first state, the latch 31 and the snap fastener 32 are separated, and in a second state, the latch 31 and the snap fastener 32 are engaged.

[0034] In this way, the locking component 30 can lock and unlock the motor 10 by engaging and disengaging the latch 31 and the snap-fit ​​32, so as to realize the first state and the second state of the locking component 30. Moreover, the engagement method of the latch 31 and the snap-fit ​​32 is relatively simple, which helps to reduce the difficulty of setting up.

[0035] In some embodiments, such as Figure 3 As shown, the locking assembly 30 also includes a drive member 33, which is used to drive the latch 31 to switch between a first state and a second state.

[0036] For example, the driving component 33 can be a drive motor, an electric telescopic rod, or other structure that can switch the position of the latch 31, and there is no limitation here.

[0037] This makes it easy to switch the locking component 30 between the first and second states via the drive component 33, thereby eliminating the need for manual control of the state change of the locking component 30 and reducing the difficulty of switching the state of the locking component 30.

[0038] In some embodiments, the drive unit 33 includes a locking coil 331 and a locking magnet 332, the locking magnet 332 being connected to the latch 31, and the locking coil 331 being mounted on the motor 10.

[0039] In this way, after the locking coil 331 is energized, the locking coil 331 drives the locking magnet 332 to move the latch 31, thereby allowing the latch 31 to switch between the first and second states. The locking coil 331 and the locking magnet 332 operate in a non-contact manner, meaning that the locking coil 331 and the locking magnet 332 do not need to make physical contact to achieve force transmission. This reduces wear and extends service life. Furthermore, by adjusting the magnitude and direction of the current flowing through the locking coil 331, the position and movement speed of the locking magnet 332 can be controlled very precisely. At the same time, this setup has a fast response speed, simple and reliable structure, energy efficiency, and high safety.

[0040] In some embodiments, such as Figures 4-8 As shown, the locking assembly 30 also includes a housing 34, which is connected to the motor 10, and the drive element 33 and part of the latch 31 are located between the housing 34 and the motor 10.

[0041] In this way, an installation space can be defined between the housing 34 and the motor 10, thereby providing an installation position for the arrangement of the drive unit 33 and the latch 31.

[0042] In some embodiments, such as Figure 3 As shown, the locking assembly 30 further includes an elastic element 35, which is located inside the housing 34 and connected between the housing 34 and the latch 31. The elastic element 35 is used to apply an elastic preload force to the latch 31 to move from the first state to the second state.

[0043] Thus, when the latch 31 switches from the first state to the second state, the force applied by the driving member 33 to the latch 31 is in the same direction as the force applied by the elastic member 35 to the latch 31. This makes it easier to reduce the magnitude of the force applied by the driving member 33 to the latch 31, thereby reducing power consumption. In particular, after the driving member 33 is de-energized, the latch 31 can also lock with the buckle 32 under the action of the elastic pre-tightening force of the elastic member 35, which further facilitates energy consumption reduction.

[0044] In some embodiments, the elastic element 35 includes structures with elastic deformation capabilities such as helical springs and flat sheet springs, which are not limited here.

[0045] In some embodiments, such as Figure 3 As shown, the latch 31 includes a first part 311 and a second part 312. The first part 311 extends out of the outer shell 34, and the second part 312 is connected to the first part 311 and located inside the outer shell 34.

[0046] It is understandable that, since the outer casing 34 is connected to the motor 10, i.e., the outer casing 34 is a stationary structure, while the latch 31 switches between the first state and the second state, i.e., the latch 31 is a moving structure. Since the locking magnet 332 is connected to the latch 31, and the second part 312 of the latch 31 is located inside the outer casing 34, i.e., the locking magnet 332 is installed in the second part 312, when the locking coil 331 drives the locking magnet 332 to move, the locking magnet 332 drives the first part 311 to move through the second part 312 to engage or disengage with the latch 32, thereby realizing the switching of the latch 31 between the first state and the second state.

[0047] In some implementations, such as Figure 3 and Figure 8 As shown, the second part 312 is provided with a slide groove 3121, and a rollable ball 36 is provided in the slide groove 3121. The ball 36 abuts between the second part 312 and the motor 10.

[0048] It is understandable that during the switching process between the first and second states of the latch 31, the second part 312 will slide relative to the outer shell 34 and the locking coil 331. In this application, the second part 312 is provided with a groove 3121, and a rolling ball 36 is provided in the groove 3121. The ball 36 abuts between the second part 312 and the motor 10. In this way, the rolling of the ball 36 in the groove 3121 can play a role in positioning and guiding the movement of the second part 312, thereby improving the movement stability of the latch 31. At the same time, the friction between the second part 312 and the motor 10 can be changed from sliding friction to rolling friction of the ball 36, thereby reducing the friction force on the second part 312 during movement, and thus reducing the energy consumption required for the latch 31 to switch between the first and second states.

[0049] Alternatively, in some implementations, the second part 312 and the outer shell 34 are slidably engaged via a slide rail. The slide rail can position and guide the movement of the second part 312, thereby improving the movement stability of the latch 31. In some embodiments, such as Figure 3 As shown, the camera module 100 also includes a detection drive component 40, which is electrically connected to the locking component 30. The detection drive component 40 is used to detect the position of the lens 20, and when the lens 20 is in a preset position, it controls the locking component 30 to switch from a first state to a second state.

[0050] It is worth noting that the preset position in this application refers to any position of the lens 20 in the direction Z of the optical axis. For example, the preset position can be the position where the focal length of the lens 20 is the smallest, or the position where the focal length of the lens 20 is the largest, or any position between the position where the focal length of the lens 20 is the smallest and the position where the focal length is the largest. No limitation is made here.

[0051] In this way, the position of the lens 20 can be detected in real time by the detection drive component 40, and the working state of the locking component 30 can be switched according to the current position of the lens 20. This helps to avoid malfunction of the locking component 30 and improves the automation level of the locking component 30.

[0052] In some application scenarios, when the camera module 100 is applied to a mobile phone, the detection driver component 40 can be electrically connected to the control panel of the mobile phone. When the detection driver component 40 detects that the user has triggered the camera function, the control panel of the mobile phone controls the detection driver component 40 to drive the locking component 30 to switch from the second state to the first state, thereby unlocking the lens 20 so that the lens 20 can achieve the autofocus function.

[0053] In some implementations, the detection drive component 40 includes a sensing magnet 41 and a sensing IC 42, with the sensing magnet 41 disposed on the lens 20 and the sensing IC 42 disposed at a preset position on the motor 10.

[0054] Thus, when the locking component 30 is in the first state, the lens 20 can move in the Z direction of the optical axis. As the lens 20 moves, the relative positions of the sensing magnet 41 and the sensing IC 42 change. Since the sensing IC 42 is set in a preset position on the motor 10, when the lens 20 moves to the preset position, the sensing IC 42 and the sensing magnet 41 are opposite each other. At this time, the sensing IC 42 determines that the lens 20 is in the preset position. Of course, when the lens 20 is in other positions, i.e., when the sensing IC 42 and the sensing magnet 41 are misaligned, it is determined that the lens 20 is not in the preset position. This facilitates the detection of whether the lens 20 is in the preset position, and the detection method is relatively simple, which helps reduce the difficulty of setting up the detection drive component 40.

[0055] The following is in conjunction with the appendix Figure 10 The control logic of the camera module 100 in some embodiments of this application is described below: When the camera module 100 is applied to a mobile phone, when the user is using the non-camera functions of the mobile phone normally, the initial state of the locking component 30 is that the elastic element 35 is compressed so that the latch 31 and the buckle 32 are engaged, thereby locking the lens 20. That is, the initial state of the locking component 30 is the second state.

[0056] When the user triggers the camera function of the mobile phone, the motor 10 controls the locking component 30 to be powered on. At this time, the latch 31 stretches the elastic element 31 and moves from the second state to the first state, that is, the locking component 30 is powered on and cooperates with the lens 20 to unlock. At this time, the camera module 100 can work normally, that is, the camera module 100 can automatically focus.

[0057] Next, when the camera function of the mobile phone is turned off, the motor 10 will drive the lens 20 to move to the preset position. At this time, the detection drive component senses that the lens 20 has returned to the preset position and controls the locking component 30 to be de-energized, so that the latch 31 moves from the first state to the second state under the action of the elastic member 35, thereby locking the lens 20.

[0058] In some embodiments, the detection drive component 40 is disposed on the motor 10 and is opposite to a preset position.

[0059] This facilitates improving the detection accuracy of the detection drive component 40 in detecting the current position of the lens 20, thereby improving the accuracy of switching the working state of the locking component 30.

[0060] In some embodiments, such as Figure 1 As shown, the motor 10 also includes a focusing magnet and a focusing coil 50. The focusing magnet is mounted on the lens 20, and the focusing coil 50 is disposed within the motor 10, with the focusing coil 50 and the focusing magnet positioned opposite each other. Thus, when the focusing coil 50 is energized, it drives the focusing magnet to move the lens 20 in the Z direction of the optical axis to achieve the focusing function of the camera module 100.

[0061] In some embodiments, the focusing coil 50 and the locking component 30 are respectively located on opposite sides of the lens 20. This ensures that the locking component 30 is not interfered with the original position of the focusing coil 50 and the position of the focusing magnet, thereby reducing the difficulty of setting the locking component 30. At the same time, the locking component 30 can make full use of the space on the side of the lens 20 away from the focusing coil 50, thereby improving space utilization.
