Description

Technical Field

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

[0002] With the popularization and development of smart electronic devices, users have increasingly higher requirements for the photography capabilities of these devices. In related technologies, the lens of the electronic device is nested inside a voice coil motor, which is itself nested within a sleeve assembly. The voice coil motor is connected to a base plate via a flexible circuit board. The extension and retraction of the sleeve drives the movement of the voice coil motor and the lens. The voice coil motor contains driving components and position sensing devices. When the lens module is extended, the user can directly touch the sleeve, and static electricity from the human body can directly enter the voice coil motor, causing damage to the driving components and position sensing devices within it.

[0003] In related technologies, a flexible circuit board is added to the housing of the voice coil motor. The flexible circuit board is connected to the substrate for grounding and static electricity discharge. However, adding another flexible circuit board will complicate the assembly process. At the same time, due to the back-and-forth expansion and contraction of the lens module, the flexible circuit board is prone to fatigue stress and cracking failure, and is more likely to have structural interference, stray light reflection and other effects. Summary of the Invention

[0004] This application aims to provide a lens module and electronic device that at least solves one of the problems in the related technology: adding a flexible circuit board leads to complicated assembly methods, and the flexible circuit board is prone to fatigue stress cracking failure, and is more likely to have structural interference, reflected stray light and other effects.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application propose a lens module, comprising: a circuit board; a lens disposed opposite to the circuit board; a drive member connected to the lens for driving the lens to move; and multiple sleeves disposed on the circuit board, the multiple sleeves being sequentially sleeved, the lens being connected to the sleeves via the drive member, the multiple sleeves being located around the drive member, and adjacent sleeves being able to move relative to each other to drive the lens to move, wherein at least a portion of any sleeve includes a conductor, and in the multiple sleeves, at least one sleeve's conductor is connected to the circuit board, and the conductor of the sleeve connected to the circuit board is connected to the ground terminal of the circuit board, and at least one conductor contact is provided between adjacent sleeves, and the conductors of the multiple sleeves are connected through the conductor contact.

[0007] Secondly, embodiments of this application provide an electronic device, including: a lens module as described in any of the first aspects.

[0008] In the embodiments of this application, the lens module includes a circuit board, a lens, a driving component, and multiple sleeves. The multiple sleeves are disposed on the circuit board and are sequentially fitted together, with adjacent sleeves capable of relative movement to achieve telescopic extension. The driving component is connected to the lens and is used to drive the lens movement. The driving component is also connected to the sleeves, so that when adjacent sleeves move relative to each other, it can drive the lens movement, achieving lens telescopic extension. At least a portion of any sleeve includes a conductor capable of electrostatic discharge. In the multiple sleeves, at least one sleeve's conductor is in contact with the circuit board. At least one conductor contact is provided between adjacent sleeves to achieve conductivity between the conductors of the multiple sleeves. Electrostatic discharge can then be transferred through the conductor contact from the conductor on the sleeve surrounding the lens to the conductors of other sleeves, and finally from the conductor on the sleeve in contact with the circuit board to the circuit board, thus releasing the electrostatic discharge. The entire conduction path does not affect light transmission and avoids the driving component, thereby providing electrostatic protection for the components inside the driving component.

[0009] Specifically, the drive unit is positioned around the lens.

[0010] Furthermore, the drive unit is connected to the sleeve, and multiple sleeves are located around the drive unit. That is, the lens and the drive unit are located inside the innermost sleeve among the multiple sleeves, and the outermost sleeve among the multiple sleeves is connected to the circuit board.

[0011] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] The following is combined Figures 1-8 This application describes a lens module and an electronic device according to embodiments thereof.

[0028] like Figure 1 and Figure 2 As shown, a lens module according to some embodiments of this application includes: a circuit board 1; a lens 2, disposed opposite to the circuit board 1; a drive member 3, connected to the lens 2, for driving the lens 2 to move; a plurality of sleeves 4, disposed on the circuit board 1, the plurality of sleeves 4 being sequentially sleeved, the lens 2 being connected to the sleeves 4 through the drive member 3, the plurality of sleeves 4 being located around the drive member 3, and adjacent sleeves 4 being able to move relative to each other to drive the lens 2 to move, wherein at least a portion of any sleeve 4 includes a conductor 40, in the plurality of sleeves 4, at least one sleeve 4 having a conductor 40 connected to the circuit board 1, and the conductor 40 of the sleeve 4 connected to the circuit board 1 being connected to the ground terminal of the circuit board 1, at least one conductor contact 5 being provided between adjacent sleeves 4, and the conductors 40 of the plurality of sleeves 4 being connected through the conductor contact 5.

[0029] In the embodiments of this application, the lens module includes a circuit board 1, a lens 2, a driving component 3, and multiple sleeves 4. The multiple sleeves 4 are disposed on the circuit board 1 and are sequentially sleeved. Adjacent sleeves 4 can move relative to each other to achieve telescopic movement. The driving component 3 is connected to the lens 2 and is used to drive the lens 2 to move. The driving component 3 is connected to the sleeves 4, so that when adjacent sleeves 4 move relative to each other, it can drive the lens 2 to move, thereby achieving telescopic movement of the lens 2. In this embodiment, at least a portion of any sleeve 4 includes a conductor 40, which enables the transfer of static electricity. Among the multiple sleeves 4, at least one sleeve 4 has a conductor 40 in contact with the circuit board 1. At least one conductor contact 5 is provided between adjacent sleeves 4 to enable the conduction of the conductors 40 of the multiple sleeves 4. Thus, static electricity can be transferred from the conductors 40 on the sleeves 4 surrounding the lens 2 to the conductors 40 of other sleeves 4 through the conductor contact 5. Finally, the static electricity is transferred from the conductors 40 on the sleeves 4 in contact with the circuit board 1 to the circuit board 1, so that the static electricity is released. The entire conduction path does not affect the transmission of light and avoids the driving component 3, thereby enabling electrostatic protection of the components inside the driving component 3.

[0030] Specifically, the drive unit 3 is arranged around the lens 2.

[0031] Furthermore, the drive unit 3 is connected to the circuit board 1 via the flexible circuit board 7 for power supply and signal transmission. Specifically, the drive unit 3 is a voice coil motor.

[0032] Furthermore, the drive unit 3 is connected to the sleeve 4, and multiple sleeves 4 are located around the drive unit 3. That is, the lens 2 and the drive unit 3 are located inside the innermost sleeve 4 among the multiple sleeves 4, and the outermost sleeve 4 among the multiple sleeves 4 is connected to the circuit board 1.

[0033] It should be noted that both the conductor 40 and the conductor contact 5 are capable of transferring static electricity, and thus the multiple sleeves 4 transfer static electricity through the conductor contact 5. Specifically, both the conductor 40 and the conductor contact 5 are made of metal. The circuit board 1 is connected to the grounding device of the electronic device, thereby releasing static electricity.

[0034] In practical applications, multiple sleeves 4 move relative to each other to keep the lens module in a retracted or extended state. When the lens module is extended, the multiple sleeves 4 extend, allowing the lens module to protrude from the electronic device's housing, enabling the user to touch the sleeves 4. Static electricity can then be transferred sequentially through the sleeves 4 to the circuit board 1, thus discharging the static charge. When the lens module is retracted, the multiple sleeves 4 retract, reducing the space they occupy.

[0035] like Figure 5 As shown, according to some embodiments of this application, the conductor contact 5 includes an elastic contact 50, which is in a compressed state between adjacent sleeves 4.

[0036] In this embodiment, the conductor contact 5 includes an elastic contact 50, which is in a compressed state between adjacent sleeves 4, thereby improving the contact reliability between the conductor contact 5 and the conductor 40.

[0037] It is understandable that the conductor contact 5 is disposed between two adjacent sleeves 4, and the conductor contact 5 is in contact with the conductor 40 of the two adjacent sleeves 4 to realize the transfer of static electricity. The conductor contact 5 is disposed between the two adjacent sleeves 4 in a compressed state, which can improve the contact tightness between the conductor contact 5 and the conductor 40 of the two adjacent sleeves 4, thereby ensuring the reliability of static electricity release.

[0038] The elastic contact element 50 between adjacent sleeves 4 can be increased or decreased as needed.

[0039] Specifically, such as Figure 5 As shown, the upper elastic contact 50 shows the state when the elastic contact 50 is not installed between two adjacent sleeves 4, and the lower elastic contact 50 shows the state when the elastic contact 50 is installed between two adjacent sleeves 4.

[0040] like Figure 3 and Figure 4 As shown, according to some embodiments of this application, the elastic contact 50 includes: an elastic member 52 disposed between adjacent sleeves 4; and a connector 54 disposed at both ends of the elastic member 52, the connector 54 being in contact with the conductor 40.

[0041] In this embodiment, the elastic contact 50 includes an elastic element 52 and a connector 54. The connector 54 is disposed at both ends of the elastic element 52 so that the elastic contact 50 forms a conductor, and the connector 54 is in contact with the conductor 40, thereby realizing the transfer of static electricity.

[0042] It is understood that both the elastic element 52 and the connector 54 are structures capable of transmitting static electricity. Specifically, both the elastic element 52 and the connector 54 are metal parts. The conductor 40 is a metal part.

[0043] In specific applications, the elastic contact 50 also includes a protective shell 56, which is sleeved on the outside of the elastic member 52, and the connector 54 can move relative to the protective shell 56.

[0044] like Figure 3 and Figure 4 As shown, according to some embodiments of this application, the elastic element 52 includes a spring or a sheet.

[0045] In this embodiment, the elastic element 52 includes a spring or a sheet spring. The spring and sheet spring are elastic. Installing the elastic contact element 50 between adjacent sleeves 4 can make the elastic contact element 50 in a compressed state, thereby improving the contact strength between the connector 54 and the conductor 40 and preventing the connector 54 from separating from the conductor 40 during the movement of adjacent sleeves 4, which would cause electrostatic discharge failure.

[0046] According to some embodiments of this application, such as Figure 3 As shown, connector 54 includes a ball connector, or Figure 4 The cylindrical connector shown.

[0047] In this embodiment, the connector 54 includes a ball joint or a cylindrical joint. The ball joint or cylindrical joint can ensure a good sliding effect, reduce friction, and thus facilitate sliding contact during the extension and contraction process.

[0048] like Figure 6 and Figure 8 As shown, according to some embodiments of this application, in two adjacent sleeves 4, at least one sleeve 4 is provided with a slide rail 42, and the two sleeves 4 are slidably connected by the slide rail 42; the first end of the conductor contact 5 is provided in one of the two adjacent sleeves 4, and the second end of the conductor contact 5 is slidably provided in the slide rail 42 of the other of the two adjacent sleeves 4, and the conductor contact 5 contacts the conductor 40 through the slide rail 42.

[0049] In this embodiment, at least one of the two adjacent sleeves 4 is provided with a slide rail 42, and the two sleeves 4 are slidably connected by the slide rail 42, thereby realizing the extension and retraction of the two sleeves 4. In the two adjacent sleeves 4 and the conductor contact 5 disposed between the two sleeves 4, the first end of the conductor contact 5 is disposed on one sleeve 4, and the second end of the conductor contact 5 is disposed in the slide rail 42 on the other sleeve 4 and can slide in the slide rail 42. That is, the first end of the conductor contact 5 is fixed on one sleeve 4, and the second end is slidably disposed in the slide rail 42. In this way, the conductor contact 5 can slide with the extension and retraction of the two sleeves 4 to realize the transfer of static electricity.

[0050] The conductor contact 5 contacts the conductor 40 via the slide rail 42, ensuring constant contact with the conductor 40 during the extension and retraction of the sleeve 4, thus achieving electrostatic transfer. Furthermore, in the adjacent sleeves 4 and the conductor contact 5 positioned between them, the first end of the conductor contact 5 is located at the lower end of the inner sleeve 4. When the lens module is in the retracted state, the conductor contact 5 can slide down to the bottom along the slide rail 42 of the sleeve 4.

[0051] In practical applications, in two adjacent sleeves 4, one sleeve 4 is provided with a slide rail 42, and the other sleeve 4 is provided with a slider. The slider is disposed within the slide rail 42 and can slide within the slide rail 42 to realize the extension and retraction of the two adjacent sleeves 4. Alternatively, in two adjacent sleeves 4, one sleeve 4 is provided with a first slide rail 42, and the other sleeve 4 is provided with a second slide rail 42. The first slide rail 42 and the second slide rail 42 can be coupled to realize the sliding of the two sleeves 4.

[0052] According to some embodiments of this application, the conductor 40 is exposed on the slide rail 42, or the slide rail 42 is the conductor 40.

[0053] In this embodiment, the conductor 40 is exposed on the slide rail 42, or the slide rail 42 is the conductor 40. This ensures that the conductor contact 5 is always in contact with the conductor 40, thus guaranteeing the reliability of electrostatic transfer.

[0054] By setting the slide rail 42 as a conductor 40, the strength of the sleeve 4 can be increased and the smoothness of sliding can be improved.

[0055] Furthermore, the conductor 40 exposed on the slide rail 42 includes the conductor 40 disposed on the surface of the slide rail 42.

[0056] like Figure 8 As shown, according to some embodiments of this application, when a slide rail 42 is provided on the inner wall surface of the outer sleeve 4 in two adjacent sleeves 4, the slide rail 42 is inclinedly disposed on the inner wall surface of the sleeve 4 along the axial direction of the sleeve 4.

[0057] In this embodiment, in two adjacent sleeves 4, one sleeve 4 is fitted on the outside of the other sleeve 4. When the inner wall surface of the outer sleeve 4 is provided with a slide rail 42, the slide rail 42 is inclinedly arranged on the inner wall surface of the sleeve 4. In this way, when multiple sleeves 4 drive the lens 2 to extend and retract, the lens 2 can also be rotated.

[0058] like Figure 2 As shown, according to some embodiments of this application, the plurality of sleeves 4 include a first sleeve 44, a second sleeve 46 and at least one third sleeve 48, the at least one third sleeve 48 being located between the first sleeve 44 and the second sleeve 46, the first sleeve 44 being located inside the third sleeve 48, the driving member 3 being disposed inside the first sleeve 44, the second sleeve 46 being connected to the circuit board 1, and the driving member 3 being connected to the circuit board 1 through the flexible circuit board 7.

[0059] In this embodiment, the plurality of sleeves 4 includes a first sleeve 44, a second sleeve 46, and at least one third sleeve 48 disposed between the first sleeve 44 and the second sleeve 46. The first sleeve 44 is disposed inside the third sleeve 48, the driving member 3 is disposed inside the first sleeve 44, and the second sleeve 46 is connected to the circuit board 1, thereby increasing the extension length of the plurality of sleeves 4. The driving member 3 is connected to the circuit board 1 via a flexible circuit board 7 for power supply and signal transmission.

[0060] It is understood that a conductor contact 5 is provided between the first sleeve 44 and the adjacent third sleeve 48, a conductor contact 5 is provided between the adjacent third sleeves 48, and a conductor contact 5 is provided between the third sleeve 48 and the second sleeve 46, thereby realizing the transfer of static electricity between the first sleeve 44, the third sleeve 48 and the second sleeve 46.

[0061] Specifically, when there is only one third sleeve 48, an elastic contact 50 is used between the conductor 40 of the first sleeve 44 and the third sleeve 48 to transfer static electricity from the top first sleeve 44 to the third sleeve 48; the same elastic contact 50 is used between the conductor 40 of the third sleeve 48 and the second sleeve 46 to conduct static electricity from the third sleeve 48 to the second sleeve 46, and finally from the second sleeve 46 to the circuit board 1, completing the static discharge and protecting the internal components of the drive unit 3. Compared with the prior art, the lens module proposed in this application does not require the addition of a flexible circuit board for grounding to achieve static electricity discharge, thereby avoiding problems such as fatigue cracking caused by long-term expansion and contraction of the flexible circuit board, which is beneficial to improving the reliability of the lens module. Furthermore, the elastic contact 50 is located between two adjacent sleeves 4, which does not affect the space of the inner cavity. That is, the elastic contact 50 is completely outside the optical path, and there is no stray light interference caused by the conduction of the flexible circuit board 7 in the related art, which makes the overall lens module design more reliable. By adding a conductor 40 to the sleeve 4 and an elastic contact 50 between the sleeves 4 to create conductivity, static electricity is transferred to the circuit board 1, completing the static discharge; the overall static discharge path is as follows: Figure 2 As shown by the arrow in the image.

[0062] According to some embodiments of this application, at least one of the first sleeve 44, the second sleeve 46 and the third sleeve 48 includes a plastic sleeve 4, and the conductor 40 is embedded in the plastic sleeve 4.

[0063] In this embodiment, at least one of the first sleeve 44, the second sleeve 46, and the third sleeve 48 includes a plastic sleeve 4, and a conductor 40 is embedded in the plastic sleeve 4. By embedding the conductor 40 in the plastic sleeve 4, static electricity can be transferred, and manufacturing costs and the overall weight of the lens module can be reduced.

[0064] In a specific application, at least one of the first sleeve 44, the second sleeve 46, and the third sleeve 48 is embedded in the conductor 40 during injection molding.

[0065] According to some embodiments of this application, at least one of the first sleeve 44, the second sleeve 46 and the third sleeve 48 is a metal sleeve 4, and the metal sleeve 4 is a conductor 40.

[0066] In this embodiment, at least one of the first sleeve 44, the second sleeve 46 and the third sleeve 48 is a metal sleeve 4, and the metal sleeve 4 is a conductor 40, thereby ensuring the reliability of electrostatic transfer.

[0067] In practical applications, when there is only one third sleeve 48, multiple sleeves 4 constitute a three-stage sleeve 4. To ensure manufacturability, size, and functional coordination between the two telescopic sleeves 4, the first sleeve 44 is made of metal, while the second sleeve 46 and the third sleeve 48 are made of plastic. Conductors 40 are embedded within the second sleeve 46 and the third sleeve 48. The lens module provided in this embodiment, when in the extended state, as... Figure 2 As shown, during use, when the user comes into contact with the first sleeve 44, the conductor 40 between the third sleeve 48 and the second sleeve 46 (if the sleeve 4 itself is metal, then it is not necessary to inject the conductor 40 inside the sleeve 4) is transferred to the third sleeve 48 using an elastic contact 50. The same elastic contact 50 is used between the third sleeve 48 and the second sleeve 46 to conduct the static electricity to the second sleeve 46. Finally, the static electricity is conducted from the second sleeve 46 to the circuit board 1 and released to the entire machine. The entire conduction path avoids the drive component 3, thus achieving the effect of electrostatic protection for the internal components of the drive component 3. The sleeve 4 has the conductor 40 embedded during injection molding.

[0068] According to some embodiments of this application, the lens 2 is embedded in the drive unit 3.

[0069] In this embodiment, the lens 2 is embedded in the driving component 3, which improves the driving effect of the driving component 3 on the lens 2.

[0070] In a specific application, a photosensitive chip 6 is set on the circuit board 1, and the lens 2 is nested in the drive component 3. The drive component 3 is nested in the first sleeve 44. The extension and retraction of the sleeve 4 drives the drive component 3 and the lens 2 to move, adjusting the distance between the lens 2 and the photosensitive chip 6 to achieve focusing and zooming functions.

[0071] According to some embodiments of this application, the sleeve 4 includes a first sleeve 44, a second sleeve 46, and a third sleeve 48. The lens 2 is embedded in the first sleeve 44, and the second sleeve 46 is connected to the circuit board 1. Each of the first sleeve 44, second sleeve 46, and third sleeve 48 includes a conductor 40. An elastic contact 50 is used between the conductors 40 of the first sleeve 44 and the third sleeve 48 to transfer static electricity from the top of the first sleeve 44 to the third sleeve 48. Similarly, the same elastic contact 50 is used between the conductors 40 of the third sleeve 48 and the second sleeve 46 to conduct static electricity from the third sleeve 48 to the second sleeve 46, and finally from the second sleeve 46 to the circuit board 1, completing static discharge and protecting the internal components of the drive unit 3. Compared to existing technologies, the lens module proposed in this application does not require an additional flexible circuit board, thus avoiding problems such as fatigue cracking caused by long-term expansion and contraction of the flexible circuit board, which is beneficial to improving the reliability of the lens module. Furthermore, the elastic contact 50 is positioned between two adjacent sleeves 4, without affecting the internal cavity space. This means the elastic contact 50 is completely outside the optical path, eliminating stray light interference caused by the flexible circuit board conduction in related technologies, thus making the overall lens module design more reliable. By adding a conductor 40 to the sleeve 4 and simultaneously adding an elastic contact 50 between the sleeves 4 to create conductivity, static electricity is transferred to the circuit board 1, completing the static discharge. The overall static discharge path is as follows: Figure 2 As shown.

[0072] like Figure 3 and Figure 4 As shown, the elastic contact 50 consists of three parts: a metal connector 54, a metal spring, and a protective shell 56. The connector 54 is a round metal ball or a semi-cylindrical metal part, which facilitates sliding contact during the extension and contraction process. The elastic element 52 is a metal spring or a spring. Through the spring or spring in the middle, the round metal balls at both ends form a conductor.

[0073] like Figure 5 As shown, during assembly, the two metal connectors 54 can be pushed inward and placed into the telescopic slide rails 42 of the two sleeves 4. After being placed in, they will extend under the action of the spring, directly connecting the two sleeves 4.

[0074] Details between sleeves 4, such as Figure 6 As shown, there is one or more elastic contact members 50 between the first sleeve 44 and the third sleeve 48. The elastic contact member 50 protruding on the first sleeve 44 is embedded in the rotary slide rail 42 of the third sleeve 48. The inner surface of the slide rail 42 is the conductor member 40. The elastic contact member 50 conducts the metal conductor member 40 of the first sleeve 44 and the third sleeve 48. When the first sleeve 44 rotates down and retracts, the first sleeve 44 and the third sleeve 48 remain in contact during the entire sliding process of the slide rail 42.

[0075] Similarly, the elastic contact 50 of the third sleeve 48 is embedded in the rotary slide rail 42 of the second sleeve 46. The inner surface of the slide rail 42 is the conductor 40. The sleeve 4 is embedded with the conductor 40 during injection molding, such as... Figure 7 As shown, the elastic contact 50 connects the conductor 40 of the third sleeve 48 and the first sleeve 44. When the third sleeve 48 rotates downward and retracts, the third sleeve 48 and the second sleeve 46 remain in contact during the entire sliding process of the slide rail 42.

[0076] The surface of the slide rail 42 is a conductor 40, which also increases the strength of the sleeve 4 and improves smoothness; the elastic contact 50 and the slide rail 42 have a suitable gap to ensure smooth sliding and always maintain the connection between the metals.

[0077] Therefore, the contact is transferred step by step from the first sleeve 44 to the elastic contact 50 to the slide rail 42, and finally the static electricity is conducted from the second sleeve 46 to the circuit board 1, and finally makes contact with the ground, thus realizing a reliable path for static electricity release.

[0078] When the lens module is in the retracted state, the elastic contact 50 slides down to the bottom along the slide rail 42 of the sleeve 4. Throughout the process, the sleeves 4 maintain a good contact state with each other through the elastic contact 50. Figure 7 As shown, the arrow indicates the electrostatic conduction path.

[0079] According to some embodiments of this application, an electronic device is also proposed, including a lens module as proposed in any of the above embodiments.
