Abstract
Description
Technical Field
[0001] This application belongs to the field of camera technology, and more specifically relates to a camera and an electronic device. Background Technology
[0002] In related technologies, cameras in electronic devices are typically equipped with optical image stabilization (OIS) and video focusing (VCM) components. These moving parts need to have gaps to allow for lens displacement compensation for hand shaking or autofocus. As a result, when the electronic device is shaken, the lens assembly will make a sound due to inertia.
[0003] Furthermore, as the imaging performance of electronic devices improves, the size and weight of cameras increase, and the operating space of the lens assembly increases accordingly, leading to increasingly severe abnormal noises. Summary of the Invention
[0004] This application aims to provide a camera and electronic device that can solve the technical problem of abnormal noise caused by the camera being affected by external force.
[0005] In a first aspect, this application provides a camera, including:
[0006] case;
[0007] The guide rod is housed within the casing.
[0008] The lens assembly is slidably connected to the guide rod;
[0009] A first magnetic component and a driving component are provided. The first magnetic component is disposed on one side of the lens assembly, and the driving component is disposed on the side of the housing opposite to the first magnetic component. The driving component is used to drive the lens assembly to slide along the guide rod through the first magnetic component.
[0010] A magnetic anti-collision component is installed inside the housing. The magnetic anti-collision component is used to limit the lens assembly when the camera is powered off.
[0011] Secondly, this application provides an electronic device, comprising:
[0012] The camera provided in the first aspect embodiment.
[0013] The camera provided in this application includes a housing, a guide rod, a lens assembly, a first magnetic component, a driving component, and a magnetic anti-collision assembly. The guide rod is fixed to the housing, the lens assembly is disposed inside the housing, and the lens assembly is slidably connected to the guide rod. The first magnetic component is disposed on the lens assembly, and the driving component is disposed on the housing. The first magnetic component is disposed on one side of the lens assembly, and the driving component is disposed on the side of the housing opposite to the first magnetic component. Thus, the driving component can drive the lens assembly to slide along the guide rod through the first magnetic component, thereby enabling the camera to have zoom capability.
[0014] When the camera is powered on, the driving component can drive the lens assembly through the first magnetic component, thereby preventing the lens assembly from colliding with the housing. When the camera is powered off, the magnetic anti-collision component limits the lens assembly, thereby preventing the lens assembly from colliding with the housing. This achieves the effect of preventing collisions between the lens assembly and the housing regardless of whether the camera is powered on or off.

[0052] The following is combined with Figures 1 to 29 This application describes a camera 10 and an electronic device 1 according to embodiments thereof.
[0053] like Figure 1 , Figure 3 , Figure 18 and Figure 21 As shown, this application provides a camera 10, including: a housing 11; a guide rod 12 disposed within the housing 11; a lens assembly 13 slidably connected to the guide rod 12; a first magnetic element 14 and a driving element 15, the first magnetic element 14 being disposed on one side of the lens assembly 13, and the driving element 15 being disposed on the side of the housing 11 opposite to the first magnetic element 14, the driving element 15 being used to drive the lens assembly 13 to slide along the guide rod 12 via the first magnetic element 14; and a magnetic anti-collision component 16 disposed within the housing 11, the magnetic anti-collision component 16 being used to limit the lens assembly 13 when the camera 10 is powered off.
[0054] The camera 10 provided in this application includes a housing 11, a guide rod 12, a lens group 13, a first magnetic element 14, a driving element 15, and a magnetic anti-collision assembly 16. The guide rod 12 is fixed to the housing 11, the lens group 13 is disposed inside the housing 11, and the lens group 13 is slidably connected to the guide rod 12. The first magnetic element 14 is disposed on the lens group 13, and the driving element 15 is disposed on the housing 11. The first magnetic element 14 is disposed on one side of the lens group 13, and the driving element 15 is disposed on the side of the housing 11 opposite to the first magnetic element 14. Thus, the driving element 15 can drive the lens group 13 to slide along the guide rod 12 through the first magnetic element 14, thereby enabling the camera 10 to have zoom capability.
[0055] When the camera 10 is powered on, the driving component 15 can drive the lens assembly 13 through the first magnetic component 14, thereby preventing the lens assembly 13 from colliding with the housing 11. When the camera 10 is powered off, the magnetic anti-collision component 16 limits the lens assembly 13, thereby preventing the lens assembly 13 from colliding with the housing 11. The effect of preventing the lens assembly 13 from colliding with the housing 11 can be achieved regardless of whether the camera 10 is powered on or off.
[0056] Among them, such as Figure 1 , Figure 2 , Figure 18 and Figure 21 As shown, the housing 11 includes a carrier 112 and a protective cover 113. The guide rod 12 is disposed on the carrier 112, the protective cover 113 is disposed on the carrier 112, and part of the magnetic anti-collision component 16 is disposed on the carrier 112.
[0057] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, according to some embodiments of this application, the magnetic anti-collision component 16 includes: a second magnetic element 161 disposed within the housing 11; and an electromagnetic component 162 disposed on the side of the second magnetic element 161 facing the lens assembly 13. When the electromagnetic component 162 is energized, the generated magnetic field cancels the magnetic field of the second magnetic element 161, causing the lens assembly 13 to be in a free state. When the electromagnetic component 162 is not energized, the lens assembly 13 is in a limited state.
[0058] Specifically, the magnetic anti-collision component 16 includes a second magnetic element 161 and an electromagnetic component 162. The second magnetic element 161 is fixed inside the housing 11, and the electromagnetic component 162 is disposed on the side of the second magnetic element 161 facing the lens assembly 13.
[0059] Among them, such as Figure 4 , Figure 12 and Figure 19 As shown, when the camera 10 is powered on, the electromagnetic component 162 is powered on, and the electromagnetic component 162 generates a magnetic field opposite to that of the second magnetic component 161, thereby canceling the magnetic field of the second magnetic component 161, so that the lens assembly 13 is in a free state. At this time, the driving component 15 is also powered on. The driving component 15 can drive the lens assembly 13 through the first magnetic component 14 to achieve the effect of stabilizing the lens assembly 13. That is, when the camera 10 is powered on, the possibility of the lens assembly 13 colliding with the housing 11 is reduced.
[0060] like Figure 5 , Figure 14 and Figure 20 As shown, when the camera 10 is not powered on, the electromagnetic component 162 is not powered on, and the electromagnetic component 162 will not generate a magnetic field opposite to that of the second magnetic component 161. The magnetic field of the second magnetic component 161 can act on the lens assembly 13, so that the lens assembly 13 is in a limited state. At this time, the driving component 15 is also not powered on, and the driving component 15 will not affect the lens assembly 13. The magnetic anti-collision component 16 achieves the effect of stabilizing the lens assembly 13. That is, when the camera 10 is not powered on, the possibility of collision between the lens assembly 13 and the housing 11 is reduced.
[0061] The camera 10 provided in this application embodiment loses its magnetism when the camera 10 is powered on, and retains its magnetism when the camera 10 is not powered on. It can have a magnetic attraction function. When the camera 10 is not working, it can rely on the magnetic attraction function to firmly hold the lens group 13, counteract the shaking and other actions during daily use, keep the lens group 13 immovable, and thereby reduce the sound generated by the impact of the lens group 13 inside the camera 10 during the shaking of the electronic device 1.
[0062] When the camera 10 is powered on, the first coil 164 is energized. The magnetic field generated by the first coil 164 cancels the magnetic field of the second magnetic component 161 itself. At this time, the second magnetic component 161 is non-magnetic and cannot attract magnetic materials, so that the lens group 13 can move and the camera 10 can work normally.
[0063] When the camera 10 is not powered on, the first coil 164 is not powered on, and the second magnetic component 161 exhibits magnetic attraction. At this time, the first magnetic component 14 tightly attracts the magnetic material, restricting the movement of the lens assembly 13, thereby reducing the possibility of sound caused by impact during daily use.
[0064] In other words, when the camera 10 is not powered on, the magnetic anti-collision component 16 provides a self-locking function for the lens group 13, reducing the collision between the lens groups 13 of the camera 10 during the shaking of the electronic device 1, thereby reducing the possibility of the camera 10 producing a collision sound, while also enabling the camera 10 to work normally.
[0065] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 As shown, according to some embodiments of this application, the magnetic anti-collision component 16 further includes: a third magnetic element 166, disposed on the side of the lens assembly 13 facing the second magnetic element 161, with the second magnetic element 161 and the third magnetic element 166 disposed opposite to each other; wherein, when the electromagnetic component 162 is energized, the generated magnetic field cancels the magnetic field of the second magnetic element 161, causing the lens assembly 13 to be in a free state; when the electromagnetic component 162 is not energized, the second magnetic element 161 attracts the third magnetic element 166, causing the lens assembly 13 to be in a limited state.
[0066] Specifically, the magnetic anti-collision assembly 16 also includes a third magnetic element 166, which is fixed on the side of the lens assembly 13 facing the second magnetic element 161, and the second magnetic element 161 and the third magnetic element 166 are arranged opposite to each other.
[0067] Among them, such as Figure 4 , Figure 12 and Figure 15 As shown, when the camera 10 is powered on, the electromagnetic component 162 is powered on, and the electromagnetic component 162 generates a magnetic field opposite to that of the second magnetic component 161, thereby canceling the magnetic field of the second magnetic component 161. The second magnetic component 161 and the third magnetic component 166 will not attract each other, so that the lens assembly 13 is in a free state. At this time, the driving component 15 is also powered on. The driving component 15 can drive the lens assembly 13 through the first magnetic component 14 to achieve the effect of stabilizing the lens assembly 13. That is, when the camera 10 is powered on, the possibility of the lens assembly 13 colliding with the housing 11 is reduced.
[0068] like Figure 5 , Figure 13 and Figure 16 As shown, when the camera 10 is not powered on, the electromagnetic component 162 is not powered on, and the electromagnetic component 162 will not generate a magnetic field opposite to that of the second magnetic component 161. The magnetic field of the second magnetic component 161 can attract the third magnetic component 166, so that the lens assembly 13 is in a limited state. At this time, the driving component 15 is also not powered on, and the driving component 15 will not affect the lens assembly 13. The magnetic anti-collision component 16 achieves the effect of stabilizing the lens assembly 13. That is, when the camera 10 is not powered on, the possibility of collision between the lens assembly 13 and the housing 11 is reduced.
[0069] According to some embodiments of this application, the camera 10 includes a housing 11, a guide rod 12, a lens assembly 13, a first magnetic component 14, a driving component 15, and a magnetic anti-collision assembly 16. The magnetic anti-collision assembly 16 includes a second magnetic component 161, an electromagnetic component 162, and a third magnetic component 166. The electromagnetic component 162 includes a base 163, a first coil 164, and a cover 165. The housing 11 includes a carrier 112 and a protective cover 113. There are two lens assemblies 13 and two magnetic anti-collision assemblies 16.
[0070] The driving element 15 can be a second coil.
[0071] The protective cover 113 is used to support and protect the internal structure. The lens group 13 is at least one movable lens. The first magnetic element 14 cooperates with the driving element 15 to provide driving force for the lens group 13. The driving element 15 cooperates with the first magnetic element 14 to provide driving force for the lens group 13.
[0072] The support column 169 of the base 163 is made of non-magnetic material. When the first coil 164 is energized, it can form an electromagnetic field and generate magnetism. Adjusting the direction of the current can change the direction of the magnetic poles of the electromagnetic field, thereby canceling the magnetism of the second magnetic component 161.
[0073] The cover 165 is used to protect the first coil 164 and reduce the possibility of the first coil 164 being exposed.
[0074] The carrier 112 is used to carry the lens and other auxiliary functional components.
[0075] The guide rod 12 provides guidance for the movement of the lens assembly 13, enabling the lens assembly 13 to reciprocate linearly along the guide rod. There can be four guide rods 12, with two used for each lens assembly 13.
[0076] The third magnetic component 166 is fixed to the lens group 13.
[0077] The second magnetic element 161 is used to cooperate with the third magnetic element 166 to attract the lens assembly 13 when the camera 10 is not powered on.
[0078] like Figure 19 As shown, when the camera 10 is powered on, the first coil 164 is powered on, and the first coil 164 generates a magnetic field opposite to that of the second magnetic component 161, thereby canceling the magnetic field of the second magnetic component 161. The second magnetic component 161 appears to be a non-magnetic component and cannot attract the first magnetic component 14, so that the lens assembly 13 can move normally.
[0079] like Figure 20 As shown, when the camera 10 is not powered on, the first coil 164 is not powered on, and the first coil 164 will not generate a magnetic field opposite to that of the second magnetic component 161. The second magnetic component 161 appears to be magnetic, and it can tightly attract the first magnetic component 14. At this time, the second magnetic component 161 tightly attracts the first magnetic component 14, thus restricting the movement of the lens assembly 13 and reducing the possibility of impact sounds during daily use.
[0080] The first coil 164 is energized by the driving circuit of the camera 10. When the camera 10 is turned on, the first coil 164 is energized at the same time. When the camera 10 is turned off, the first coil 164 is energized at the same time. The whole process is autonomously controlled by the driving circuit of the camera 10.
[0081] The lens assembly 13 and the third magnetic component 166 can be fixed by means of snap-fit or adhesive.
[0082] The second magnetic component 161 and the housing 11 can be fixed by means of snap-fit or adhesive.
[0083] The electromagnetic component 162 and the housing 11 or the second magnetic component 161 can be fixed by means of snap-fit or adhesive.
[0084] The second magnetic component 161 is first fixed to the housing 11, and then the electromagnetic component 162 is fixed to the second magnetic component 161 and the housing 11.
[0085] Electromagnetic component 162 covers second magnetic component 161.
[0086] The base 163 has a support post 169, a first coil 164 is wound around the outside of the support post 169, and a cover 165 covers the combination of the base 163 and the first coil 164 to protect the base 163 and the first coil 164.
[0087] When the camera 10 is powered on, the first coil 164 is energized. The magnetic field generated by the first coil 164 cancels the magnetic field of the second magnetic component 161 itself. At this time, the second magnetic component 161 appears to be non-magnetic and cannot attract the third magnetic component 166. The lens assembly can move, so that the camera 10 can work normally.
[0088] When the camera 10 is not powered on, the first coil 164 is not powered on, and the second magnetic component 161 exhibits magnetic attraction. At this time, the first magnetic component 14 tightly attracts the third magnetic component 166, restricting the movement of the lens assembly 13, thereby reducing the possibility of sound caused by impact during daily use.
[0089] The first coil 164 is energized by the driving circuit of the camera 10. When the camera 10 is turned on, the first coil 164 is energized at the same time. When the camera 10 is turned off, the first coil 164 is energized at the same time. The whole process is autonomously controlled by the driving circuit of the camera 10.
[0090] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, according to some embodiments of this application, the housing 11 includes a first perimeter 111, a second magnetic element 161 is disposed within the first perimeter 111, and an electromagnetic element 162 is located at the end of the first perimeter 111; the lens assembly 13 includes a second perimeter 131, and a third magnetic element 166 is disposed within the second perimeter 131.
[0091] Specifically, the housing 11 includes a first perimeter 111, a second magnetic element 161 fixed inside the first perimeter 111, and an electromagnetic element 162 located at the end of the first perimeter 111, that is, the electromagnetic element 162 is located between the second magnetic element 161 and the third magnetic element 166. The third magnetic element 166 is disposed inside the second perimeter 131, thereby fixing the magnetic anti-collision assembly 16. Furthermore, the first perimeter 111 protects the second magnetic element 161, and the second perimeter 131 protects the third magnetic element 166, thereby reducing the possibility of the magnetic anti-collision assembly 16 falling off.
[0092] like Figure 18 , Figure 19 and Figure 20 As shown, according to some embodiments of this application, when the electromagnetic component 162 is energized, the generated magnetic field cancels the magnetic field of the second magnetic component 161, so that the lens assembly 13 is in a free state. When the electromagnetic component 162 is not energized, the second magnetic component 161 attracts the first magnetic component 14, so that the lens assembly 13 is in a limited state.
[0093] Specifically, such as Figure 19 As shown, when the camera 10 is powered on, the electromagnetic component 162 is powered on, and the electromagnetic component 162 generates a magnetic field opposite to that of the second magnetic component 161, thereby canceling the magnetic field of the second magnetic component 161. The second magnetic component 161 and the first magnetic component 14 will not attract each other, so that the lens assembly 13 is in a free state. At this time, the driving component 15 is also powered on. The driving component 15 can drive the lens assembly 13 through the first magnetic component 14, thereby stabilizing the lens assembly 13. That is, when the camera 10 is powered on, the possibility of the lens assembly 13 colliding with the housing 11 is reduced.
[0094] like Figure 20 As shown, when the camera 10 is not powered on, the electromagnetic component 162 is not powered on, and the electromagnetic component 162 will not generate a magnetic field opposite to that of the second magnetic component 161. The magnetic field of the second magnetic component 161 can attract the first magnetic component 14, so that the lens assembly 13 is in a limited state. At this time, the driving component 15 is also not powered on, and the driving component 15 will not affect the lens assembly 13. The magnetic anti-collision component 16 achieves the effect of stabilizing the lens assembly 13. That is, when the camera 10 is not powered on, the possibility of collision between the lens assembly 13 and the housing 11 is reduced.
[0095] According to some embodiments of this application, the camera 10 includes a housing 11, a guide rod 12, a lens assembly 13, a first magnetic component 14, a driving component 15, and a magnetic anti-collision assembly 16. The magnetic anti-collision assembly 16 includes a second magnetic component 161 and an electromagnetic component 162. The electromagnetic component 162 includes a base 163, a first coil 164, and a cover 165. The housing 11 includes a carrier 112 and a protective cover 113. There are two lens assemblies 13 and two magnetic anti-collision assemblies 16.
[0096] The driving element 15 can be a second coil.
[0097] The protective cover 113 is used to support and protect the internal structure. The lens group 13 is at least one movable lens. The first magnetic element 14 cooperates with the driving element 15 to provide driving force for the lens group 13. The driving element 15 cooperates with the first magnetic element 14 to provide driving force for the lens group 13.
[0098] The support column 169 of the base 163 is made of non-magnetic material. When the first coil 164 is energized, it can form an electromagnetic field and generate magnetism. Adjusting the direction of the current can change the direction of the magnetic poles of the electromagnetic field, thereby canceling the magnetism of the second magnetic component 161.
[0099] The cover 165 is used to protect the first coil 164 and reduce the possibility of the first coil 164 being exposed.
[0100] The carrier 112 is used to carry the lens and other auxiliary functional components.
[0101] The guide rod 12 provides guidance for the movement of the lens assembly 13, enabling the lens assembly 13 to reciprocate linearly along the guide rod. There can be four guide rods 12, with two used for each lens assembly 13.
[0102] The second magnetic element 161 is used to cooperate with the first magnetic element 14 to attract the lens assembly 13 when the camera 10 is not powered on.
[0103] like Figure 19 As shown, when the camera 10 is powered on, the first coil 164 is powered on, and the first coil 164 generates a magnetic field opposite to that of the second magnetic component 161, thereby canceling the magnetic field of the second magnetic component 161. The second magnetic component 161 appears to be a non-magnetic component and cannot attract the first magnetic component 14, so that the lens assembly 13 can move normally.
[0104] like Figure 20 As shown, when the camera 10 is not powered on, the first coil 164 is not powered on, and the first coil 164 will not generate a magnetic field opposite to that of the second magnetic component 161. The second magnetic component 161 appears to be magnetic, and it can tightly attract the first magnetic component 14. At this time, the second magnetic component 161 tightly attracts the first magnetic component 14, thus restricting the movement of the lens assembly 13 and reducing the possibility of impact sounds during daily use.
[0105] The first coil 164 is energized by the driving circuit of the camera 10. When the camera 10 is turned on, the first coil 164 is energized at the same time. When the camera 10 is turned off, the first coil 164 is energized at the same time. The whole process is autonomously controlled by the driving circuit of the camera 10.
[0106] like Figure 1 , Figure 3 and Figure 18 As shown, according to some embodiments of this application, the first magnetic element 14 and the second magnetic element 161 are located on adjacent sides of the lens group 13, respectively.
[0107] Specifically, the first magnetic element 14 and the second magnetic element 161 are located on adjacent sides of the lens group 13, thereby reducing the possibility of interference between the driving element 15 and the second magnetic element 161.
[0108] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 10 , Figure 11 and Figure 18 As shown, according to some embodiments of this application, the electromagnetic component 162 includes: a base 163, the base 163 including a support column 169; a first coil 164 disposed around the support column 169; and a cover 165 covering the base 163; wherein the first coil 164 is located within the space enclosed by the base 163 and the cover 165.
[0109] Specifically, the electromagnetic component 162 includes a base 163, a first coil 164, and a cover 165. The base 163 includes a support column 169, and the first coil 164 is arranged around the support column 169, so that the first coil 164 can be firmly fixed to the base 163. The cover 165 covers the base 163, and the first coil 164 is located within the space enclosed by the base 163 and the cover 165, thereby achieving the effect of protecting the first coil 164.
[0110] like Figure 21 , Figure 23 , Figure 24 , Figure 25 , Figure 26 , Figure 27 and Figure 28 As shown, according to some embodiments of this application, the magnetic anti-collision component 16 includes: a fourth magnetic element 167 disposed on the surface of one of the housing 11 and the lens group 13; and a metal tube 168 disposed on the surface of the other of the housing 11 and the lens group 13, wherein the metal tube 168 is made of a non-magnetic material; wherein the fourth magnetic element 167 and the metal tube 168 are disposed opposite to each other, and when the fourth magnetic element 167 and the metal tube 168 move toward each other, the fourth magnetic element 167 penetrates into the metal tube 168.
[0111] Specifically, the magnetic anti-collision component 16 includes a fourth magnetic element 167 and a metal tube 168. The fourth magnetic element 167 is disposed on the surface of one of the housing 11 and the lens assembly 13, and the metal tube 168 is disposed on the surface of the other of the housing 11 and the lens assembly 13. The metal tube 168 is made of a non-magnetic material, and the fourth magnetic element 167 and the metal tube 168 are disposed opposite to each other.
[0112] like Figure 22 As shown, when the fourth magnetic component 167 and the metal tube 168 move towards each other, the fourth magnetic component 167 penetrates the metal tube 168. The metal tube 168 senses the changing magnetic field caused by the change in the position of the fourth magnetic component 167, and generates a circular current inside the metal tube 168. The direction of the magnetic field generated by the current is always consistent with the direction of the fourth magnetic component 167 that enters. As a result, the magnetic field of the metal tube 168 and the fourth magnetic component 167 have a magnetic attraction effect, which generates damping and can prevent the lens assembly 13 from continuing to move, thereby reducing the possibility of collision between the lens assembly 13 and the housing 11.
[0113] Among them, such as Figure 23 As shown, when the camera 10 is powered on, the driving component 15 is also powered on. The driving component 15 can drive the lens group 13 through the first magnetic component 14 to achieve the effect of stabilizing the lens group 13. That is, when the camera 10 is powered on, the possibility of the lens group 13 and the housing 11 colliding is reduced.
[0114] like Figure 24 As shown, when the camera 10 is not powered on, the drive component 15 is also not powered on. The drive component 15 will not affect the lens group 13. When the lens group 13 shakes, the fourth magnetic component 167 enters the metal tube 168, thereby generating current in the metal tube 168, thus forming a magnetic field, preventing the fourth magnetic component 167 from continuing to move forward, achieving the effect of stabilizing the lens group 13. That is, when the camera 10 is not powered on, the possibility of the lens group 13 colliding with the housing 11 is reduced.
[0115] Specifically, the magnitude of the eddy current generated by the metal tube 168 is determined by the speed at which the fourth magnetic component 167 enters the metal tube 168. The greater the speed, the greater the current, and vice versa. The direction of the current is determined by the direction of the magnetic field when the fourth magnetic component 167 enters. The whole process follows the right-hand screw rule. The direction of the magnetic field of the eddy current generated by the eddy current will always be consistent with the direction of the magnetic field of the fourth magnetic component 167. This results in a magnetic attraction effect between the magnetic field of the eddy current and the magnetic field of the fourth magnetic component 167, generating damping and preventing the lens assembly 13 from continuing to move.
[0116] Specifically, the camera 10 provided in this application embodiment utilizes the magnetic eddy current effect to suppress the impact of the lens assembly 13 on the housing 11 when shaken, thereby improving the problem of the camera 10 being prone to impact sounds.
[0117] The magnetic eddy current effect refers to the phenomenon where, when a piece of metal is placed in a changing magnetic field or moves relative to a changing magnetic field, a closed-loop induced current is generated inside the metal. This current is similar to a vortex in water, hence the name eddy current. Eddy currents can cause thermal effects and may affect mechanical properties such as damping and vibration.
[0118] The camera 10 includes a fourth magnetic element 167 and a metal tube 168. The fourth magnetic element 167 can be a conventional magnet, and the metal tube 168 is made of a non-ferrous, non-nickel material. Optionally, the metal tube 168 can be made of aluminum or copper. To achieve the eddy current effect, the material of the metal tube 168 needs to have the property of being non-magnetic but conductive.
[0119] like Figure 22 As shown, when the fourth magnetic component 167 enters the metal tube 168, the metal tube 168 senses the changing magnetic field, thereby generating a ring current inside the metal tube 168. When the fourth magnetic component 167 enters the metal tube 168, the eddy current generated by the metal tube 168 generates a new magnetic field. The direction of the magnetic field generated by the eddy current is always consistent with the direction of the magnetic field of the fourth magnetic component 167. Therefore, the magnetic field generated by the eddy current and the fourth magnetic component 167 produce a magnetic attraction effect, generating damping, which can prevent the movable part from continuing to move.
[0120] like Figure 23 As shown, when the camera 10 is powered on, the fourth magnetic component 167 will not enter the metal tube 168, the metal tube 168 will not generate an eddy current effect, and the camera 10 can work normally.
[0121] like Figure 24 As shown, when the camera 10 is not powered on, when the camera 10 is shaken, the fourth magnetic component 167 will enter the metal tube 168 to generate an eddy current effect, preventing the lens group 13 from colliding with each other and preventing the lens group 13 from colliding with the housing 11, thereby preventing the generation of impact sound.
[0122] like Figure 25 , Figure 26 , Figure 27 and Figure 28 As shown, a fourth magnetic component 167 and a metal tube 168 are arranged at both ends of the lens assembly 13, which can prevent the sound from being generated by impact on both sides.
[0123] Furthermore, the fourth magnetic component 167 and the metal tube 168 are purely physical electromagnetic damping devices, which do not consume electrical energy, thereby reducing the energy consumption of the camera 10.
[0124] like Figure 25 , Figure 26 , Figure 27 and Figure 28As shown, according to some embodiments of this application, along the guiding direction of the guide rod 12, both ends of a lens assembly 13 are provided with metal tubes 168 or fourth magnetic elements 167, so that the movement of the lens assembly 13 in both directions can be better restricted.
[0125] like Figure 21 , Figure 23 and Figure 24 As shown, according to some embodiments of this application, the lens assembly 13 includes a protrusion 132, and a metal tube 168 is sleeved on the protrusion.
[0126] like Figure 1 , Figure 3 , Figure 18 and Figure 21 As shown, according to some embodiments of this application, there are two lens groups 13 and two magnetic anti-collision components 16, and the lens groups 13 and magnetic anti-collision components 16 are arranged in a one-to-one correspondence.
[0127] Specifically, there are two lens groups 13 to improve the shooting performance of the camera 10, and there are two magnetic anti-collision components 16. The lens groups 13 and the magnetic anti-collision components 16 are set in a one-to-one correspondence so that each lens group 13 can be reliably limited.
[0128] Secondly, such as Figure 29 As shown, this application provides an electronic device 1, including: a camera 10 as provided in the first aspect embodiment.
