Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to a camera module and electronic equipment. Background Art
[0002] In the related art, the camera of an electronic device usually has focusing and anti-shake functions. Specifically, the lens is driven to move by a driving device. During the shooting process, focusing is achieved by moving the lens. When the electronic device shakes, the anti-shake function can also be achieved by moving the lens based on the direction of the shaking.
[0003] However, since the lens can move, when the camera shakes, the lens may collide with other parts, thus generating noise. The main method for traditional cameras to reduce noise is to reduce the weight of movable parts or optimize the structure of the collision position, such as using soft-on-hard or soft-on-soft. The above methods are all to reduce noise generation from the source during the design stage, but the camera itself has no other prevention or reduction measures for the noise after the collision. Summary of the invention
[0004] The present application aims to provide a camera module and an electronic device, which can solve the technical problem in the related art that the movable parts of the camera collide with other parts to generate noise.
[0005] In a first aspect, an embodiment of the present application provides a camera module, including:
[0006] Base;
[0007] Lens;
[0008] A carrier is movably connected to the base, and is used for carrying the lens;
[0009] The silencer assembly is connected to the base and is used to reduce the noise transmitted by the collision when the carrier collides during movement.
[0010] In a second aspect, an embodiment of the present application provides an electronic device, including:
[0011] Motherboard;
[0012] As in the camera module of the first aspect, the camera module is electrically connected to the mainboard.
[0013] The camera module of the embodiment of the present application is provided with a carrier that moves relative to the base. During the process of shooting by the camera module, the carrier can be moved to drive the lens on the carrier to move, so as to achieve the focus or anti-shake function of the camera module. Furthermore, by providing a silencer component, during the process of the carrier moving relative to the base, if the carrier collides with the base, the silencer component, or other components of the camera module, the noise generated by the collision can be transmitted to the silencer component, so that the sound waves of the generated noise are attenuated by the silencer component, thereby reducing the propagation of noise, that is, reducing the noise transmitted by the collision, so as to improve the user experience of the camera module.

[0029] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, and internal communication between two elements.

[0030] Combine the following Figures 1 to 9 Describe a camera module and an electronic device according to an embodiment of the present application.
[0031] In some embodiments of the present application, a camera module is provided. Figure 1 FIG. 1 shows one of the structural schematic diagrams of the camera module of an embodiment of the present application; Figure 1 As shown, the camera module 100 includes: a base 102; a carrier 104, which is movably connected to the base 102, and the carrier 104 is used to carry the lens 134; a silencer component 106, which is connected to the base 102, and the silencer component 106 is used to reduce the noise transmitted by the collision when the carrier 104 collides during movement.
[0032] In the embodiment of the present application, the camera module 100 may include a base 102 and a carrier 104, wherein the carrier 104 is movably connected to the base 102, and the carrier 104 is used to carry the lens 134. It is understandable that the carrier 104 can move relative to the base 102, and the lens 134 is carried on the carrier 104, so that the lens 134 can move relative to the base 102. In this way, during the shooting process of the camera module 100, the lens 134 is driven by the carrier 104 to move relative to the base 102, and then the focus function during the shooting process is realized by changing the position of the lens 134. At the same time, the anti-shake function of the camera module 100 can also be realized through the movement of the lens 134.
[0033] Furthermore, the camera module 100 may also include a silencer component 106, which is connected to the base 102. It can be understood that the silencer component 106 has the function of reducing noise. For noise that has already occurred, the silencer component 106 can attenuate the sound waves of the noise, thereby reducing the propagation of the noise, that is, reducing the noise transmitted by the collision.
[0034] It should be noted that, since the carrier 104 can move relative to the base 102, during the process of the camera module 100 shooting, the carrier 104 can be moved, thereby driving the lens 134 on the carrier 104 to move, so as to realize the focus or anti-shake function of the camera module 100. At this time, the carrier 104 may collide with the base 102, the muffler assembly 106, or other components in the camera module 100, thereby generating noise. Or the camera does not shoot, but the camera module 100 shakes, and due to gravity and inertia, the carrier 104 moves relative to the base 102, and then the carrier 104 may collide with the base 102, the muffler assembly 106, or other components of the camera module 100, thereby generating noise.
[0035] By setting the silencer component 106, when the carrier 104 moves, if the carrier 104 collides, the noise generated by the collision is transmitted to the silencer component 106, so that the sound waves of the generated noise are attenuated by the silencer component 106, thereby reducing the propagation of the noise, that is, reducing the noise transmitted by the collision, so as to improve the user experience.
[0036] The camera module 100 of the embodiment of the present application is provided with a carrier 104 that moves relative to the base 102. During the process of shooting of the camera module 100, the carrier 104 can be moved, thereby driving the lens 134 on the carrier 104 to move, so as to realize the focus or anti-shake function of the camera module 100. Furthermore, by providing a muffler assembly 106, during the process of the carrier 104 moving relative to the base 102, if the carrier 104 collides with the base 102, the muffler assembly 106, or other components of the camera module 100, the noise generated by the collision can be transmitted to the muffler assembly 106, so that the sound waves of the generated noise are attenuated by the muffler assembly 106, thereby reducing the propagation of the noise, that is, reducing the noise transmitted by the collision, so as to improve the user experience of the camera module 100.
[0037] In some embodiments of the present application, Figure 2 Shows Figure 1 The structural diagram of the silencer assembly; Figure 2 As shown, the sound-absorbing component 106 includes: a shell 108 connected to the base 102 , and a receiving space 112 is defined in the shell 108 ; and a sound-absorbing material 110 is disposed in the receiving space 112 .
[0038] In the embodiment of the present application, the muffler assembly 106 may include a shell 108 and a muffler material 110 located in the shell 108, wherein the shell 108 is connected to the base 102, and a receiving space 112 is provided inside the shell 108, so that the muffler material 110 can be arranged in the receiving space 112. The muffler material 110 can attenuate the sound waves of the noise when the sound waves emitted by the collision are transmitted to the muffler material 110, so as to reduce the propagation of the noise, that is, to reduce the noise transmitted by the collision. At the same time, by wrapping the muffler material 110 with the shell 108, the muffler material 110 can also be protected, so as to prevent the muffler material 110 from directly contacting the external environment, thereby preventing dust and other impurities from adhering to the muffler material 110 and affecting the muffler effect.
[0039] In addition, it should be noted that the shell 108 is connected to the base 102. When the carrier 104 collides with the base 102 during the movement of the carrier 104, the sound waves of the noise can be transmitted from the base 102 to the shell 108, and then transmitted from the shell 108 to the sound-absorbing material 110 inside the shell 108, so that the sound waves of the noise are attenuated by the sound-absorbing material 110. If the carrier 104 collides directly with the shell 108, the sound waves of the noise are directly transmitted through the shell 108 to the sound-absorbing material 110 inside, and then the sound waves of the noise are attenuated by the sound-absorbing material 110.
[0040] In some embodiments of the present application, Figure 2As shown, at least one muffler hole 114 is formed on the shell 108 , and the muffler hole 114 is communicated with the accommodating space 112 .
[0041] In the embodiment of the present application, at least one muffler hole 114 may be provided on the shell 108, and at least one muffler hole 114 is connected to the accommodating space 112 of the shell 108. By setting at least one muffler hole 114, on the one hand, the sound waves of the noise generated by the collision can be attenuated. It is understandable that when there are multiple muffler holes 114 on the shell 108, a porous structure can be formed by multiple muffler holes 114. In the process of the sound waves of the noise passing through the porous structure, the sound waves of the noise are converted into heat energy through the friction of the porous structure and dissipated, thereby achieving the purpose of reducing the noise. On the other hand, through at least one muffler hole 114 on the shell 108, the sound waves of the noise can also be transmitted to the accommodating space 112 of the shell 108, and then the sound waves of the noise are attenuated by the muffler material 110 in the accommodating space 112, further improving the noise reduction effect.
[0042] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the housing 108 is disposed around the carrier 104 , and the housing 108 and the base 102 enclose a limiting space 116 , and the limiting space 116 is used to limit the movement range of the carrier 104 .
[0043] In the embodiment of the present application, the shell 108 can be arranged around the carrier 104, that is, the shell 108 is located in the circumferential direction of the carrier 104. In this way, when the carrier 104 collides with the base 102, the silencer assembly 106 or other components of the camera module 100, the noise generated by the collision can be effectively transmitted to the silencer material 110 in the shell 108, thereby ensuring the silencer effect of the silencer assembly 106.
[0044] Furthermore, the housing 108 can also enclose a limited space 116 with the base 102, so that the moving range of the carrier 104 is limited by the limited space 116, ensuring that the carrier 104 can move within the limited moving range and preventing the carrier 104 from leaving the effective moving range. In addition, the housing 108 and the base 102 enclose the carrier 104, and the housing 108 and the base 102 can also protect the carrier 104 and the lens 134 on the carrier 104, preventing the carrier 104 and the lens 134 from being damaged by collision with external objects.
[0045] In some embodiments of the present application, the sound-absorbing material 110 includes a porous sound-absorbing material.
[0046] In the embodiment of the present application, the sound-absorbing material 110 can be a porous sound-absorbing material, such as glass wool, mineral wool, rock wool, felt, wood wool sound-absorbing board, etc. These materials have a porous structure, and when the sound waves of the noise pass through the porous material, they can be converted into heat energy and dissipated through the friction of the pore wall, thereby achieving the purpose of reducing the noise.
[0047] In some embodiments of the present application, Figure 3 Shows Figure 1 One of the structural diagrams of the medium carrier; Figure 4 Shows Figure 1 Schematic diagram of the structure of the medium carrier Figure 2 ; Figure 5 Shows Figure 1 Schematic diagram of the structure of the middle base;
[0048] Figure 6 The second structural diagram of the camera module of the embodiment of the present application is shown; Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, at least one guide hole 118 is opened on the carrier 104 , and the base 102 is provided with at least one guide column 120 . The guide hole 118 is inserted into the guide column 120 , and the carrier 104 moves relative to the base 102 along the extension direction of the guide column 120 .
[0049] In the embodiment of the present application, at least one guide hole 118 may be opened on the carrier 104, and correspondingly, at least one guide column 120 may be provided on the base 102. By inserting the guide hole 118 into the guide column 120, the movement of the carrier 104 can be guided during the movement of the carrier 104 relative to the base 102.
[0050] Specifically, the extension direction of the guide column 120 can be the same as the movement direction of the lens 134 when the camera module 100 is focused, so that the carrier 104 can achieve the focusing function in the process of driving the lens 134 to move.
[0051] In some embodiments of the present application, Figure 1 As shown, the camera module 100 further includes: a driving component 122 , which is disposed between the base 102 and the carrier 104 , and the driving component 122 is used to drive the carrier 104 to move relative to the base 102 .
[0052] In the embodiment of the present application, the camera module 100 may further include a driving component 122, and the driving component 122 is respectively connected to the carrier 104 and the base 102, so that the carrier 104 can be driven by the driving component 122, so that the carrier 104 can drive the lens 134 to move relative to the base 102, thereby realizing the focus or anti-shake function of the camera module 100.
[0053] Specifically, when the camera module 100 is applied to an electronic device 300, the driving component 122 can be electrically connected to the mainboard 302 of the electronic device 300, so that the control chip of the electronic device 300 can send a driving signal to the driving component 122 through the mainboard 302, and supply power to the driving component 122 through the power supply of the electronic device 300, thereby realizing the operation of the driving component 122 to drive the carrier 104.
[0054] Exemplarily, the drive assembly 122 may be an electromagnetic drive assembly, a motor drive assembly, or a hydraulic drive assembly.
[0055] In some embodiments of the present application, Figure 7 The third structural diagram of the camera module of the embodiment of the present application is shown; Figure 1 , Figure 6 and Figure 7 As shown, the driving component 122 includes: a magnetic member 124, which is arranged on the carrier 104; a coil 126, which is arranged on the base 102, and the coil 126 is located within the magnetic field range of the magnetic member 124; wherein, when the coil 126 is energized, the coil 126 generates a magnetic force that interacts with the magnetic member 124.
[0056] In an embodiment of the present application, the driving component 122 may include a magnetic component 124 and a coil 126, so as to generate a magnetic force through the electromagnetic induction phenomenon of the coil 126, and then the magnetic force generated by the coil 126 interacts with the magnetic field of the magnetic component 124 to achieve relative movement between the magnetic component 124 and the coil 126.
[0057] Specifically, the magnetic member 124 can be arranged on the carrier 104, and correspondingly, the coil 126 is arranged on the base 102, and the coil 126 is located within the magnetic field range of the magnetic member 124. When the coil 126 is energized, based on the principle of electromagnetic induction, a magnetic field is generated around the coil 126, that is, the coil 126 can generate a magnetic force after being energized. At the same time, the coil 126 is located within the magnetic field range of the magnetic member 124. When the coil 126 generates a magnetic force, the magnetic force of the coil 126 can interact with the magnetic field of the magnetic member 124, thereby achieving mutual repulsion or mutual attraction. At this time, the direction and magnitude of the magnetic force generated by the coil 126 can be controlled by controlling the direction and magnitude of the current in the coil 126, so as to achieve the control of the moving direction and moving speed of the carrier 104. At the same time, the magnetic member 124 is arranged on the carrier 104, and the coil 126 is arranged on the base 102, so as to achieve the driving carrier 104 to move relative to the base 102, and then drive the lens 134 to move through the carrier 104 to achieve the focusing or anti-shake function.
[0058] Furthermore, the number of magnetic members 124 can be set to multiple, and the magnetic members 124 can be set at different positions of the carrier 104, so as to drive the carrier 104 at different positions of the carrier 104, ensure the balance of force on the carrier 104, and further ensure the stability of the carrier 104 during movement.
[0059] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the carrier 104 defines a mounting slot 128 , and the magnetic member 124 is located in the mounting slot 128 .
[0060] In the embodiment of the present application, a mounting groove 128 may be provided on the carrier 104, and the magnetic member 124 may be provided in the mounting groove 128. The mounting groove 128 may be provided to enable the magnetic member 124 to be installed. Meanwhile, during the interaction between the magnetic member 124 and the magnetic force generated by the coil 126, the magnetic member 124 may abut against the side wall of the mounting groove 128, thereby driving the carrier 104 to move.
[0061] Specifically, the number of the mounting grooves 128 can be set to two, and the two mounting grooves 128 are symmetrically opened on both sides of the carrier 104. Correspondingly, the number of the magnetic members 124 is also two, which are respectively arranged in the two mounting grooves 128.
[0062] In some embodiments of the present application, Figure 5 and Figure 6 As shown, a plurality of winding posts 130 are disposed on the base 102 , and the coil 126 is wound around the plurality of winding posts 130 .
[0063] In the embodiment of the present application, a plurality of winding posts 130 may be provided on the base 102 , so that the coil 126 may be wound on the plurality of winding posts 130 to achieve connection between the coil 126 and the base 102 .
[0064] Specifically, the number of winding poles 130 can be set to four, and the four winding poles 130 are evenly distributed on one side of the base 102 along the axis of the base 102, and then the coil 126 is wound on the four winding poles 130 by a winding machine to achieve the setting of the coil 126.
[0065] In addition, the coil 126 may be set on the base 102 by glue, snaps or other methods.
[0066] In some embodiments of the present application, Figure 8 FIG. 4 shows a fourth structural diagram of a camera module according to an embodiment of the present application; Figure 1 and Figure 8 As shown, the camera module 100 also includes: a cover body 132 connected to the base 102 , and the cover body 132 covers the carrier 104 and the noise reduction component 106 .
[0067] In the embodiment of the present application, the camera module 100 may further include a cover body 132, which is connected to the base 102 through the cover body 132, so that the cover body 132 can cover the carrier 104 and the silencer assembly 106, thereby achieving protection of the carrier 104, the lens 134 on the carrier 104, and the silencer assembly 106 through the cover body 132, and preventing the carrier 104, the lens 134 on the carrier 104, and the silencer assembly 106 from being damaged by collision with external objects.
[0068] Furthermore, the cover 132 can be made of a metal material with strong magnetic conductivity. On the one hand, the metal material has strong hardness and can effectively withstand the collision of external objects, thereby ensuring the protection effect of the carrier 104 inside the cover 132, the lens 134 on the carrier 104, and the muffler assembly 106. On the other hand, the cover 132 can reduce the interference of external magnetic elements on the magnetic components of the camera module 100, such as the magnetic member 124 and the coil 126 of the driving assembly 122, thereby ensuring the stable operation of the camera module 100.
