Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to a camera module and an electronic device. Background Technology

[0002] With the development of technology, electronic devices have become commonplace items in people's daily lives. Typically, electronic devices are equipped with camera modules, which can capture images and videos.

[0003] In the related technology of slider motor camera module, because the slider is relatively smooth, when the camera module is not working, such as when moving electronic devices, the motor carrier will move uncontrollably along the slider on the track, hitting the housing of the camera module and generating noise, which affects the user experience. Summary of the Invention

[0004] This application provides a camera module and an electronic device that can solve the problem in the prior art where the collision between the carrier and the housing of the camera module generates abnormal noise, affecting the user experience.

[0005] In a first aspect, embodiments of this application provide a camera module, including: a housing having a cavity; a support portion housed within the cavity, the support portion being used to support a lens, the support portion being movably disposed relative to the housing in a first direction; and an adjustment portion including an adjustment mechanism and an electric field mechanism, the adjustment mechanism being disposed between the housing and the support portion to restrict the movement of the support portion, the adjustment mechanism being an electrorheological elastomer, the electric field mechanism being disposed in the housing, the electric field mechanism being used to generate an electric field to adjust the stiffness of the adjustment mechanism, and when the adjustment mechanism is located in the electric field, the stiffness of the adjustment mechanism is increased, and the support portion can move relative to the housing.

[0006] Secondly, embodiments of this application provide an electronic device including the camera module described in the first aspect embodiment.

[0007] Thus, in the camera module and electronic device provided in this application embodiment, the camera module includes a housing, a support portion, and an adjustment portion. The housing has a cavity, and the support portion for carrying the lens is accommodated in the cavity. The support portion is movably disposed relative to the housing in a first direction. The adjustment portion includes an adjustment mechanism and an electric field mechanism. The adjustment mechanism is an electrorheological elastic body disposed between the housing and the support portion to restrict the movement of the support portion. The electric field mechanism is disposed in the housing. When the adjustment mechanism is located in an electric field, the adjustment mechanism can undergo a phase change within the electric field generated by the electric field mechanism, thereby increasing the stiffness of the adjustment mechanism and allowing the support portion to move relative to the housing.

[0008] Therefore, in this embodiment, an adjustment part is provided between the housing and the support part, and an electric field mechanism is provided in the cavity. The adjustment mechanism is a electrorheological elastomer. The electric field mechanism can control the phase change of the electrorheological elastomer, thereby adjusting the stiffness of the electrorheological elastomer. When the stiffness of the electrorheological elastomer increases, the contact area between the housing and the support part and the adjustment mechanism decreases, and the friction decreases, so that the support part can move smoothly relative to the housing. When the stiffness of the electrorheological elastomer decreases, the contact area between the housing and the support part and the adjustment mechanism increases, and the friction increases. The adjustment mechanism blocks the relative movement of the support part and the housing, so as to improve the collision noise problem of the support part and the housing in the first direction and improve the user experience.

[0028] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the structure of a camera module according to some embodiments of this application; Figure 2 Exploded views of camera modules according to some embodiments of this application; Figure 3 For some embodiments of this application Figure 1 Sectional view at point AA.

[0029] Firstly, such as Figures 1 to 3 As shown, this application embodiment provides a camera module 100, which includes a housing 200, a support portion 300, and an adjustment portion 400. The housing 200 has a cavity 210; the support portion 300 is housed within the cavity 210 and is used to support a lens. The support portion 300 is movably disposed relative to the housing 200 in a first direction X; the adjustment portion 400 includes an adjustment mechanism 410 and an electric field mechanism 420. The adjustment mechanism 410 is disposed between the housing 200 and the support portion 300 to restrict the movement of the support portion 300. The adjustment mechanism 410 is an electrorheological elastic body. The electric field mechanism 420 is disposed on the housing 200 and is used to generate an electric field to adjust the stiffness of the adjustment mechanism 410. When the adjustment mechanism 410 is in the electric field, the stiffness of the adjustment mechanism 410 increases, and the support portion 300 can move relative to the housing 200.

[0030] In the camera module 100 and electronic device provided in this application embodiment, the camera module 100 includes a housing 200, a support portion 300, and an adjustment portion 400. The housing 200 has a cavity 210, and the support portion 300 for supporting the lens is accommodated in the cavity 210. The support portion 300 is movably disposed relative to the housing 200 in a first direction X. The adjustment portion 400 includes an adjustment mechanism 410 and an electric field mechanism 420. The adjustment mechanism 410 is an electrorheological elastic body disposed between the housing 200 and the support portion 300 to restrict the movement of the support portion 300. The electric field mechanism 420 is disposed on the housing 200. When the adjustment mechanism 410 is located in an electric field, the adjustment mechanism 410 can undergo a phase change in the electric field generated by the electric field mechanism 420, the stiffness of the adjustment mechanism 410 increases, and the support portion 300 can move relative to the housing 200. An adjustment part 400 is provided between the housing 200 and the support part 300, and an electric field mechanism 420 is provided in the chamber 210. The adjustment mechanism 410 is a electrorheological elastomer. The electric field mechanism 420 can control the phase change of the electrorheological elastomer, thereby adjusting the stiffness of the electrorheological elastomer. When the stiffness of the electrorheological elastomer increases, the contact area between the housing 200 and the support part 300 and the adjustment mechanism 410 decreases, and the friction decreases, allowing the support part 300 to move smoothly relative to the housing 200. When the stiffness of the electrorheological elastomer decreases, the contact area between the housing 200 and the support part 300 and the adjustment mechanism 410 increases, and the friction increases. The adjustment mechanism 410 blocks the relative movement of the support part 300 and the housing 200, thereby improving the collision noise problem between the support part 300 and the housing 200 in the first direction X and improving the user experience. The housing 200 is used to accommodate the support part 300 and the adjustment part 400. The housing 200 has a first light-transmitting hole and a second light-transmitting hole at both ends in the first direction X. Optionally, the first direction X is the optical axis direction of the camera module 100.

[0031] The camera module 100 also includes a photosensitive chip, which is an important component of the camera module 100. The photosensitive chip can be a CCD (Charge Coupled Device) or a CMOS (Complementary Metal-Oxide Semiconductor).

[0032] The carrier 300 is used to support the lens. The carrier 300 is provided with a third light-transmitting hole. The lens is fixed to the third light-transmitting hole. External light passes through the first light-transmitting hole, the lens and the second light-transmitting hole to reach the photosensitive chip. The photosensitive chip can be set opposite to the lens. The photosensitive chip is used to receive the light collected by the lens and perform photoelectric conversion to realize the shooting function of the camera module 100. The carrier 300 is movably set relative to the housing 200 in the first direction X so that the position between the lens and the photosensitive chip is adjustable to realize the focusing and image stabilization functions of the camera module 100.

[0033] The camera module 100 also includes a drive unit 500, which drives the support unit 300 to move relative to the housing 200. The drive unit 500 includes a drive mechanism 510 and a fixing mechanism 520. The drive mechanism 510 is disposed in the housing 200, and the fixing mechanism 520 is connected to the support unit 300. The drive mechanism 510 applies a force to the fixing mechanism 520, and the fixing mechanism 520 drives the support unit 300 to move relative to the housing 200. The drive mechanism 510 can be an electric motor, and the fixing mechanism 520 can be a rack and pinion, with the output end of the electric motor meshing with the rack and pinion. Alternatively, the drive mechanism 510 can be an electromagnetic coil, and the fixing mechanism 520 can be a permanent magnet, with the support unit 300 moving under the force between the electromagnetic coil and the permanent magnet.

[0034] The adjustment unit 400 includes an adjustment mechanism 410 and an electric field mechanism 420. The adjustment mechanism 410 is an electrorheological elastomer, a type of electrorheological material. Electrorheological elastomers are composite elastomers obtained by dispersing rheological particles in a gel network of polymer compounds through physicochemical methods. A characteristic of electrorheological materials is that under the influence of an applied electric field, they undergo a phase transition within millimeter-scale time, changing from fluid to viscoelastic to viscoelastic-plastic to a solid-like state. This process significantly alters their apparent viscosity, elastic modulus, and shear modulus, making them intelligent materials whose rheological properties can be controlled by an applied electric field. When the applied electric field is removed, they rapidly and reversibly revert from a solid-like state back to their original liquid state. Therefore, the characteristic of an electrorheological elastomer is that it can transform from a viscoelastic to a solid-like state under the influence of an applied electric field, and then transform back into a viscoelastic state after the electric field is removed.

[0035] Specifically, since the support portion 300 and the housing 200 can move relative to each other in the first direction X, a gap exists between the support portion 300 and the housing 200. The adjustment mechanism is disposed between the housing and the support portion, that is, the adjustment mechanism 410 is accommodated within at least part of the gap. When the adjustment mechanism 410 is in a high-rigidity state similar to a solid, the contact area between the support portion 300 and the adjustment mechanism 410 is small, the friction is reduced, and the support portion 300 and the housing 200 can move relative to each other smoothly. When the adjustment mechanism 410 is in a low-rigidity state similar to a viscoelastic body, under the action of an external force such as the weight of the part, the support portion 300 compresses the low-rigidity adjustment mechanism 410, causing deformation. The contact area between the support portion 300 and the adjustment mechanism 410 increases, and the friction between them increases, thereby preventing relative movement between the support portion 300 and the housing 200.

[0036] The adjustment mechanism 410 can be connected to either the support portion 300 or the housing 200, or the adjustment mechanism 410 can be abutted against both the support portion 300 and the housing 200. The shape and size of the adjustment mechanism 410 can be flexibly designed.

[0037] Optionally, the adjustment mechanism 410 fills the entire gap to improve the control effect of the adjustment mechanism 410 on the bearing portion 300.

[0038] The electric field mechanism 420 is used to generate an electric field that controls the phase change of the regulating mechanism 410. The electric field mechanism 420 can be a conductor directly connected to the regulating mechanism 410; or the electric field mechanism 420 can be a conductor mechanism spaced apart from the regulating mechanism 410. For example, the electromagnetic coil of the drive unit 500 can be reused as the electric field mechanism 420. When the electromagnetic coil is energized to drive the carrier unit 300 to move, the electric field generated by the electromagnetic coil causes the regulating mechanism 410 to change phase, thereby reducing the number of parts in the chamber 210; or the electric field mechanism 420 can be an electrode plate 421 connected to the cavity wall. The regulating mechanism is set between two opposing electrode plates 421. The two electrode plates 421 are a positive electrode plate and a negative electrode plate, respectively. A stable magnetic field can be generated between the positive and negative electrode plates to stably control the deformation of the regulating mechanism 410.

[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, the camera module 100 is configured to include a working state and a non-working state. In the working state, the electric field mechanism 420 is energized to generate an electric field, the adjustment mechanism 410 is located in the electric field, the stiffness of the adjustment mechanism 410 is increased, and the support part 300 can move relative to the housing 200. In the non-working state, the electric field mechanism 420 is de-energized, and the stiffness of the adjustment mechanism 410 decreases to limit the movement of the support part 300.

[0040] In these embodiments, in the non-operating state, the electric field mechanism 420 is de-energized, the phase change stiffness of the adjustment mechanism 410 decreases, the contact area between the housing 200 and the support part 300 and the adjustment mechanism 410 increases, and the friction increases. The adjustment mechanism 410 blocks the relative movement of the support part 300 and the housing 200 to improve the collision noise problem between the support part 300 and the housing 200 in the first direction X. In the operating state, the electric field mechanism 420 is energized to generate an electric field, and the adjustment mechanism 410 is located in the electric field. The stiffness of the adjustment mechanism 410 increases, the contact area between the housing 200 and the support part 300 and the adjustment mechanism 410 decreases, and the friction decreases. The support part 300 can move smoothly relative to the housing 200 to realize the image stabilization and zoom functions of the camera module.

[0041] The camera module 100 is configured to include a working state and a non-working state. When the camera module 100 needs to take a picture or record a video, the camera module 100 is in the working state, and when the camera module 100 does not need to take a picture or record a video, the camera module 100 is in the non-working state.

[0042] Please see Figure 4 , Figure 4 For some embodiments of this application Figure 1 Sectional view at point BB.

[0043] In some embodiments, such as Figures 2 to 4 As shown, the housing 200 includes a wall panel 220 and a guide member 230 connected to the wall panel 220. The guide member 230 is located in the chamber 210. The support portion 300 and the guide member 230 are movably connected relative to each other in a first direction X. An adjustment mechanism 410 is provided on at least one of the guide member 230 and the support portion 300.

[0044] In these embodiments, a guide member 230 is provided inside the housing 200, and the support portion 300 and the guide member 230 are movably connected relative to each other in the first direction X to realize the relative movement of the support portion 300 and the housing 200 in the first direction X. The adjustment mechanism 410 is provided on at least one of the guide member 230 and the support portion 300, which can realize the control effect of the adjustment portion 400 on the support portion 300 while reducing the volume of the adjustment mechanism 410 and reducing the material cost of the equipment.

[0045] The support part 300 is connected to the housing through the guide member 230. During the movement of the support part, the guide member 230 plays a role in fixing and guiding the support part 300.

[0046] Optionally, the guide member 230 may be either a groove or a slider disposed on the wall panel 220, and the other may be a slider or a groove disposed on the support portion 300, with at least a portion of the slider accommodated within the groove, and the adjusting mechanism 410 disposed on the inner wall of the groove and / or the surface of the slider; or the guide member 230 may be a slide rod connected to the wall panel 220 and extending along the first direction X, with the support portion 300 sleeved on the slide rod through a connecting hole, and the adjusting mechanism 410 disposed on the outer surface of the slide rod and / or the inner surface of the connecting hole 311; or the guide member 230 may be a first limiting groove disposed on the wall panel 220 and extending along the first direction X, and a ball disposed within the limiting groove, with a second limiting groove disposed on the surface of the support portion 300, the ball being located between the first and second limiting grooves, and the adjusting mechanism 410 disposed on the inner surface of the second limiting groove and / or the first limiting groove.

[0047] Please see Figure 5 , Figure 5 This is a partial structural schematic diagram of a camera module according to some embodiments of this application.

[0048] In some embodiments, such as Figure 2 and Figure 5 As shown, the guide member 230 extends in the first direction X, and the support part 300 is provided with a connecting hole 311. The support part 300 is sleeved on the guide member 230 through the connecting hole 311. The adjustment mechanism 410 is provided on at least one of the inner wall of the guide member 230 or the connecting hole 311.

[0049] In these embodiments, the guide member 230 extends in the first direction X, and the support portion 300 is provided with a connecting hole 311. The support portion 300 is sleeved on the guide member 230 through the connecting hole 311 so that the support portion 300 can move relative to the housing 200 in the first direction X. The cooperation between the guide member 230 and the connecting hole 311 ensures that the support portion 300 and the housing 200 can be stably connected when the device is rotated in various directions. The adjustment mechanism 410 is provided on at least one of the inner wall of the guide member 230 or the connecting hole 311 so that the adjustment mechanism 410 can prevent the support portion 300 from moving in the non-working state.

[0050] The guide member 230 extends along the first direction X and is connected to the cavity wall of the chamber 210 in the first direction X. The guide member 230 is a slide rod. For example, the guide member 230 can be a rectangular slide rod or a cylindrical slide rod, etc.

[0051] The diameter of the connecting hole 311 is larger than the size of the guide 230 so that the guide 230 can pass through the connecting hole 311.

[0052] Optionally, the chamber 210 is provided with two or more guide members 230, and the bearing part 300 is provided with two or more connecting holes 311 to enhance the movement stability of the bearing part 300.

[0053] The adjustment mechanism 410 is disposed between at least a portion of the outer surface of the guide member 230 and at least a portion of the inner wall surface of the connecting hole 311, so that in the non-working state, the bearing part 300 contacts the guide member 230 through the adjustment mechanism 410, so that the adjustment mechanism 410 can limit the relative movement of the bearing part 300 and the guide member 230.

[0054] The shape of the adjustment mechanism 410 can be flexibly designed. For example, the adjustment mechanism 410 can be arc-shaped, ring-shaped, or block-shaped.

[0055] Please see Figure 6 , Figure 6 This is a partial structural schematic diagram of a camera module according to other embodiments of this application.

[0056] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the adjustment mechanism 410 is sleeved on the guide member 230, and the bearing part 300 is sleeved on the adjustment mechanism 410 through the connecting hole 311.

[0057] In these embodiments, the adjustment mechanism 410 is sleeved on the guide member 230, and the bearing part 300 is sleeved on the adjustment mechanism 410 through the connection hole 311. The adjustment mechanism 410 sleeved on the guide member 230 can ensure contact with the bearing part 300 when the equipment is flipped and moved in all directions, thereby improving the reliability of the adjustment mechanism 410.

[0058] Specifically, the adjustment mechanism 410 is fixed to the guide member 230 to reduce the difficulty of setting up the adjustment part 400. The adjustment mechanism 410 and the guide member 230 can be fixed by bonding; or both ends of the adjustment mechanism 410 can extend along the first direction X and abut against the cavity wall; or the adjustment part 400 can be bonded to the inner wall of the connection hole 311 to ensure that in the non-working state, the bearing part 300 is connected through the adjustment mechanism 410 and the guide member 230, thereby improving the reliability of the adjustment part 400.

[0059] The specific shape of the adjusting mechanism 410 can be flexibly designed. The shape of the outer surface of the adjusting mechanism 410 matches the connecting hole 311, and the shape of the through hole of the adjusting mechanism 410 matches the shape of the guide 230. For example, the adjusting hole is a circular hole, the guide 230 is a cylindrical rod, and the adjusting mechanism 410 is annular.

[0060] In some embodiments, such as Figure 2 and Figure 5 As shown, the adjustment mechanism 410 has the same dimension in the first direction X as the guide member 230 in the first direction X.

[0061] In these embodiments, the size of the adjustment mechanism 410 in the first direction X is the same as the size of the guide member 230 in the first direction, which increases the arrangement area of ​​the adjustment mechanism 410 to ensure that the support part 300 can contact the adjustment mechanism 410 when not in operation, thereby improving the reliability of the adjustment part 400.

[0062] The support portion 300 moves relative to the guide member 230 in the first direction X, and the adjustment mechanism 410 covers the entire guide member 230 in the first direction X to ensure that the support portion 300 will contact the guide member 230 through the adjustment mechanism 410 in the non-working state.

[0063] Optionally, the adjustment mechanism 410 covers the entire outer surface of the guide member 230 to ensure that the bearing part 300 will contact the guide member 230 through the adjustment mechanism 410 when not in operation.

[0064] Optionally, the adjustment mechanism 410 is fixedly connected to the cavity wall at one end in the first direction X to improve the stability of the adjustment mechanism 410.

[0065] Optionally, the adjustment mechanism 410 is bonded to the guide member 230 to improve the stability of the adjustment mechanism 410.

[0066] Please see Figure 7 , Figure 7 For other embodiments of this application Figure 1 Sectional view at point AA.

[0067] In some embodiments, such as Figure 2 and Figure 7 As shown, the guide member 230 is provided with a receiving groove 2313, and the adjustment mechanism 410 is provided in the receiving groove 2313. The adjustment mechanism 41 is at least partially provided between the guide member 230 and the bearing part 300.

[0068] In these embodiments, the adjustment mechanism 410 is disposed in the receiving groove 2313 of the guide member 230. The receiving groove 2313 serves to fix the adjustment mechanism 410, so as to reduce the amount of adjustment mechanism 410 used and reduce equipment costs, while ensuring that the position of the adjustment mechanism 41 is fixed. When not in operation, the bearing part 300 can contact the guide member 230 through the adjustment mechanism 41.

[0069] Specifically, the guide member 230 includes a first segment 2311 and a second segment 2312 that are connected to each other. A receiving groove 2313 is disposed at the first segment 2311, and an adjustment mechanism 410 is disposed in the receiving groove 2313. That is, the first segment 2311 and the second segment 2312 are coaxially arranged. The outer diameter of the first segment 2311 is smaller than the outer diameter of the second segment 2312. The receiving groove 2313 is disposed on the outer surface of the guide member 230 at the first segment 2311.

[0070] When the camera module 100 changes from the working state to the non-working state, the drive unit 500 resets the support unit 300. In the first direction X, the hole wall of the connecting hole 311 is in the first segment 2311, and the support unit 300 contacts the guide member 230 through the adjustment mechanism 410.

[0071] Optionally, the first segment 2311 can be disposed at any position of the guide 230 in the first direction X. For example, the first segment 2311 is located at the end of the guide 230 in the first direction X.

[0072] Optionally, the adjustment mechanism 410 is bonded to the guide member 230 on the outer surface of the first segment 2311 to fix the adjustment mechanism 410 and the guide member 230.

[0073] Optionally, the outer surface of the adjusting mechanism 410 and the outer surface of the second segment 2312 are flush to ensure that the bearing portion 300 slides smoothly on the guide member 230.

[0074] In some embodiments, such as Figure 2 and Figure 3 As shown, the electric field mechanism 420 includes at least two electrode plates 421 arranged opposite to each other, and the adjustment mechanism 410 is located between the at least two electrode plates 421.

[0075] In these embodiments, the adjustment mechanism 410 is positioned between two opposing electrode plates 421 so that the adjustment mechanism 410 can be located in a stable electric field provided by the electrode plates 421 so that the stiffness of the adjustment mechanism 410 can be adjusted by the electrode plates 421.

[0076] Specifically, the adjustment mechanism 410 is located between two opposing electrode plates 421, which are a positive electrode plate and a negative electrode plate, respectively. In the working state, the electrode plates 421 are energized, and a stable electric field is formed between the positive and negative electrodes plate to control the adjustment mechanism 410 to generate a phase change and increase stiffness. In the non-working state, the electrode plates 421 are de-energized, the electric field between the positive and negative electrodes plate disappears, the adjustment mechanism 410 generates a phase change, and the stiffness decreases.

[0077] When the drive unit 500 is energized, a current with a constantly changing direction is passed through the electromagnetic coil to fix the support unit 300 in a specific position. This causes the electric field generated by the electromagnetic coil to be unstable. Therefore, in the solution of this embodiment, an electrode plate 421 is additionally provided so that the adjustment mechanism 410 is placed in the stable electric field of the electrode plate 421.

[0078] Optionally, the circuit board is disposed at the end of the housing 200 in the first direction X, and the electrode 421 is electrically connected to the outside through the circuit board.

The housing 200 includes an insulating material, and the electrode sheet 421 is insulated from external devices through the housing 200.

[0080] In these embodiments, at least one electrode 421 is disposed on the side surface of the housing 200 facing the chamber 210. The housing 200 includes an insulating material, and the electrode 421 is insulated from external devices through the housing 200 to reduce the risk of conduction between the electrode 421 and external components and improve the reliability of the camera module 100.

[0081] Optionally, the electrode sheet 421 is bonded to the cavity wall of the chamber 210.

[0082] Optionally, two electrode plates 421 are arranged opposite each other along a first direction X. Each electrode plate 421 has a first through hole, a first light-transmitting hole, and a second light-transmitting hole connected to the first through hole. The electrode plate 421 also has a second through hole, through which the guide member 230 is connected to the cavity wall.

[0083] Optionally, two electrode plates 421 are arranged opposite each other along the first direction X, and the electrode plates 421 cover the two side surfaces of the chamber 210 in the first direction X, and the electrode plates 421 play a supporting role for the chamber 210.
