Description

Technical Field

[0001] This application belongs to the field of motors, specifically relating to a motor and a camera module electronic device. Background Technology

[0002] With the development of technology, electronic devices are becoming increasingly widely used, enabling them to capture images, watch videos, and more. Typically, to improve the image quality captured by electronic devices, the camera module on these devices needs to be able to focus. In related technologies, the camera module includes a motor and a lens. By mounting the lens on the motor, the motor moves the lens, thus achieving focusing. However, in these technologies, the motor is significantly affected by external magnetic fields, which in turn makes the camera module highly susceptible to external magnetic field influences. Summary of the Invention

[0003] The purpose of this application is to provide an electronic device for a motor and a camera module, which at least solves the problem that the motor is greatly affected by external magnetic fields, which in turn makes the camera module greatly affected by external magnetic fields.

[0004] In a first aspect, embodiments of this application provide a motor, the motor comprising: a housing, a base, a carrier, a coil assembly, a magnetic assembly, and a conductive slide rod assembly;

[0005] The housing has a receiving cavity and an opening, the opening communicating with the receiving cavity, the base blocking the opening, and the slide rod assembly, the carrier, the coil assembly, and the magnetic assembly all located in the receiving cavity;

[0006] The first end of the slide rod assembly is electrically connected to the base, the carrier is slidably connected to the slide rod assembly, the carrier is used to support the lens of the camera module, the coil assembly is fixed to the carrier, the magnetic assembly is fixed to the cavity wall of the receiving cavity, and the magnetic assembly and the coil assembly are positioned opposite each other, the slide rod assembly is electrically connected to the coil assembly, and the slide rod assembly is used to supply power to the coil assembly so that the coil assembly drives the carrier to slide relative to the slide rod assembly.

[0007] Secondly, embodiments of this application provide a camera module, the camera module including a lens and the motor described in the first aspect above;

[0008] The lens is supported on the carrier.

[0009] Thirdly, embodiments of this application provide an electronic device, which includes the camera module described in the second aspect above.

[0010] In this embodiment, the housing has a receiving cavity and an opening, with the opening communicating with the receiving cavity. The base blocks the opening, thus forming a receiving space between the base and the housing. This allows the sliding rod assembly, the carrier, the coil assembly, and the magnetic assembly to be housed within the receiving cavity, protecting them. Since the first end of the sliding rod assembly is electrically connected to the base, and the carrier is slidably connected to the sliding rod assembly, the carrier can slide relative to the sliding rod assembly. After the lens of the camera module is mounted on the carrier, the carrier can move the lens, enabling the camera module to focus. Because the coil assembly is fixed to the carrier, and the magnetic assembly is fixed to the cavity wall of the receiving cavity, with the magnetic assembly and coil assembly positioned opposite each other, and the sliding rod assembly is electrically connected to the coil assembly, power can be supplied to the coil assembly through the sliding rod assembly. This generates a magnetic field, which interacts with the magnetic assembly to move the carrier, which in turn moves the lens assembly, achieving focusing of the camera module. In other words, in this embodiment, by setting the sliding rod assembly to be conductive and electrically connected to the coil assembly on the carrier, and fixing the magnetic assembly to the inner wall of the housing cavity, the coil assembly is effectively movable while the magnetic assembly is fixed. Power is supplied to the coil assembly through the sliding rod assembly, which enables the coil assembly to drive the carrier to move, and the carrier to drive the lens to move, thus enabling the camera module to focus. In addition, the coil assembly is fixed on the carrier, and the magnetic assembly is fixed to the cavity wall. The coil assembly has a small response to external magnetic fields, meaning that the external magnetic field has a small impact on the coil assembly, which makes the motor less affected by external magnetic fields, and thus the camera module less affected by external magnetic fields.

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] like Figures 1 to 7 As shown, the motor includes: a housing 10, a base 20, a carrier 30, a coil assembly 40, a magnetic assembly 50, and a conductive slide rod assembly 60.

[0024] The housing 10 has a receiving cavity and an opening, the opening being connected to the receiving cavity. The base 20 blocks the opening. The slide rod assembly 60, the carrier 30, the coil assembly 40, and the magnetic assembly 50 are all located in the receiving cavity. The first end of the slide rod assembly 60 is electrically connected to the base 20. The carrier 30 is slidably connected to the slide rod assembly 60. The carrier 30 is used to support the lens of the camera module. The coil assembly 40 is fixed to the carrier 30. The magnetic assembly 50 is fixed to the cavity wall of the receiving cavity, and the magnetic assembly 50 and the coil assembly 40 are positioned opposite each other. The slide rod assembly 60 is electrically connected to the coil assembly 40, and the slide rod assembly 60 is used to supply power to the coil assembly 40 so that the coil assembly 40 drives the carrier 30 to slide relative to the slide rod assembly 60.

[0025] In this embodiment, since the housing 10 has a receiving cavity and an opening, and the opening communicates with the receiving cavity, and the base 20 blocks the opening, the base 20 and the housing 10 can form a receiving space. This allows the slide rod assembly 60, the carrier 30, the coil assembly 40, and the magnetic assembly 50 to be all disposed within the receiving cavity, thus protecting them. Because the first end of the slide rod assembly 60 is electrically connected to the base 20, and the carrier 30 is slidably connected to the slide rod assembly 60, the carrier 30 can slide relative to the slide rod assembly 60. Therefore, after the lens of the camera module is mounted on the carrier 30, the carrier 30 can move the lens, enabling the camera module to focus. Since the coil assembly 40 is fixed to the carrier 30, the magnetic assembly 50 is fixed to the cavity wall of the receiving cavity, and the magnetic assembly 50 and the coil assembly 40 are positioned opposite each other, and the slide rod assembly 60 is electrically connected to the coil assembly 40, power can be supplied to the coil assembly 40 through the slide rod assembly 60, so that the coil assembly 40 can generate a magnetic field. The interaction between this magnetic field and the magnetic assembly 50 can cause the coil assembly 40 to move the carrier 30, thereby causing the carrier 30 to move the lens assembly and achieve focusing of the camera module. In other words, in this embodiment, by setting the slide rod assembly 60 to be conductive and electrically connected to the coil assembly 40 on the carrier 30, and fixing the magnetic assembly 50 to the inner wall of the receiving cavity of the housing 10, the coil assembly 40 is movable and the magnetic assembly 50 is fixed. Power is supplied to the coil assembly 40 through the slide rod assembly 60, which enables the coil assembly 40 to drive the carrier 30 to move, and the carrier 30 to drive the lens to move, thereby enabling the camera module to focus. In addition, the coil assembly 40 is fixed on the carrier 30, and the magnetic assembly 50 is fixed to the cavity wall of the receiving cavity. The coil assembly 40 has a small response to external magnetic fields, that is, the external magnetic field has a small impact on the coil assembly 40, which makes the motor less affected by the external magnetic field, and thus the camera module less affected by the external magnetic field.

[0026] It should be noted that, in the embodiments of this application, the coil assembly 40 may include a plurality of conductive coils 41, and the magnetic assembly 50 may include a plurality of magnets 51. The plurality of conductive coils 41 may be fixed at intervals on the outer wall of the carrier 30 along the circumferential direction of the carrier 30, and the plurality of magnets 51 may be fixed on the cavity wall of the receiving cavity along the circumferential direction of the carrier 30. Moreover, one conductive coil 41 corresponds to one magnet 51, and the plurality of conductive coils 41 may be electrically connected to the slide rod assembly 60. Thus, once the slide rod assembly 60 supplies power to the plurality of conductive coils 41, the plurality of conductive coils 41 may simultaneously drive the carrier 30 to move.

[0027] For example, the coil assembly 40 includes four conductive coils 41, and the magnetic assembly 50 includes four magnets 51. The four magnets 51 are fixed at intervals along the circumferential direction of the support body 30 on the outer wall of the support body 30, and the four magnets 51 are fixed along the circumferential direction of the support body 30 on the cavity wall of the receiving cavity. Each magnet 51 corresponds to one conductive coil 41, and all four conductive coils 41 are electrically connected to the slide rod assembly 60. As another example, the coil assembly 40 includes six conductive coils 41, and the magnetic assembly 50 includes six magnets 51. The specific number of conductive coils 41 and magnets 51 is not limited in this embodiment.

[0028] Furthermore, in this embodiment, the slider assembly 60 can be made of a metal material, thus making it conductive. For example, the slider assembly 60 can be made of copper, or, for another example, of silver. Of course, the slider assembly 60 can also be made of other conductive materials. This embodiment does not limit the specific material of the slider assembly 60.

[0029] In addition, in this embodiment, the base 20 can be a circuit board; of course, the base 20 can also be made of a conductive material. This embodiment does not limit the specific application in this regard. Furthermore, the first end of the slider assembly 60 can be soldered to the base 20, making an electrical connection between the slider assembly 60 and the base 20, thereby allowing the base 20 to transfer electrical energy to the slider assembly 60.

[0030] Additionally, in some embodiments, such as Figure 1 As shown, the slide rod assembly 60 may include multiple slide rods 61, each of which is conductive. The first end of each slide rod 61 is electrically connected to the base 20, and each slide rod 61 is slidably connected to the carrier 30. At least one slide rod 61 is electrically connected to the coil assembly 40. A slide rod sleeve 62 is fitted on at least one slide rod 61. The slide rod sleeve 62 has an inclined surface along the axial direction of the slide rod 61. A pressure sensor 301 is fixed on the carrier 30, and the pressure sensor 301 abuts against the inclined surface on the slide rod sleeve 62. During the movement of the carrier 30, the carrier 30 drives the pressure sensor 301 to move, so that the pressure sensor 301 abuts against different positions of the inclined surface, and the inclined surface transmits different pressures to the pressure sensor 301.

[0031] Since the slide rod assembly 60 may include multiple slide rods 61, and each slide rod 61 is slidably connected to the carrier 30, the carrier 30 can move along the multiple slide rods 61 during movement, thus making the movement of the carrier 30 more stable. Since each slide rod 61 is conductive, its first end is electrically connected to the base 20, and at least one slide rod 61 is electrically connected to the coil assembly 40, power can be supplied to the coil assembly 40 through the slide rods 61 electrically connected to it. This causes the coil assembly 40 to move the carrier 30, which in turn causes the carrier 30 to move the lens. Since at least one sliding rod 61 is fitted with a sliding rod sleeve 62, and the sliding rod sleeve 62 has an inclined surface along the axial direction of the sliding rod 61, and a pressure sensor 301 is fixed on the support body 30, the pressure sensor 301 abuts against the inclined surface on the sliding rod sleeve 62. Therefore, once the sliding rod 61 supplies power to the coil assembly 40, the coil assembly 40 drives the support body 30 to move, and the support body 30 can drive the pressure sensor 301 to move. Since the pressure sensor 301 abuts against the inclined surface on the sliding rod sleeve 62, the pressure sensor 301 experiences different pressures at different positions on the inclined surface during the movement. Thus, the specific position of the pressure sensor 301 can be determined based on the different forces acting on it, thereby determining the specific position of the support body 30. This allows for precise determination of the lens position, enabling the camera module to accurately determine the lens position during focusing, which is beneficial for the camera module to focus. In this embodiment of the application, by providing an inclined surface on the slide sleeve 62, it is beneficial to accurately determine the position of the support body 30 when the support body 30 drives the pressure sensor 301 to move, and thus accurately determine the position of the lens.

[0032] It should be noted that, in the embodiments of this application, the pressure sensing element 301 can be a pressure sensor.

[0033] In addition, in this embodiment, the slide sleeve 62 can be fixed on the slide rod 61, thereby avoiding the problem of the pressure sensor 301 moving the slide sleeve 62 when the carrier 30 moves the pressure sensor 301.

[0034] In addition, the first end of each sliding rod 61 can be welded to the base 20, so that each sliding rod 61 is electrically connected to the base 20.

[0035] In addition, in this embodiment, the slide sleeve 62 can be a conical sleeve, and the outer surface of the slide sleeve 62 forms an inclined surface. By making the slide sleeve 62 a conical sleeve, the outer surface of the conical sleeve can be directly formed into an inclined surface, thereby ensuring that the pressure sensor 301 experiences different pressures when it moves along the axial direction of the slide rod 61. That is, by setting the slide rod 61 to a conical sleeve, it is convenient to set an inclined surface on the slide sleeve 62, thereby facilitating the pressure sensor 301 to be subjected to different pressures.

[0036] Of course, in this embodiment, a groove can also be provided on the outer wall of the slide sleeve 62 along the axial direction of the slide sleeve 62, and the bottom of the groove is inclined, so that the bottom of the groove forms an inclined surface. A boss can also be provided on the outer wall of the slide sleeve 62 along the axial direction of the slide sleeve 62, and the surface of the boss facing away from the slide sleeve 62 is inclined along the axial direction of the slide sleeve 62, so that the surface of the boss facing away from the slide sleeve 62 forms an inclined surface. This embodiment does not limit the method of providing the inclined surface of the slide sleeve 62.

[0037] In some embodiments, the pressure sensor 301 is electrically connected to the sliding rod 61 that is not fitted with the sliding rod sleeve 62.

[0038] With this configuration, the sliding rod 61 can simultaneously power both the coil assembly 40 and the pressure sensor 301, avoiding the need for additional power supply to the pressure sensor 301 and thus reducing costs.

[0039] It should be noted that the carrier 30 may be provided with wires or conductive parts, which are electrically connected to the pressure sensor 301 and the coil assembly 40. The sliding rod 61 is connected to the conductive parts or conductive parts, so that the sliding rod 61 can supply power to both the coil assembly 40 and the pressure sensor 301 at the same time.

[0040] Additionally, in some embodiments, such as Figure 2 As shown, the carrier 30 may be provided with multiple sliding holes 31. The sliding holes 31 penetrate the carrier 30 in the direction of sliding of the carrier 30. A sliding rod 61 passes through a sliding hole 31. An installation groove 32 is provided on the hole wall of the sliding hole 31 through which the sliding rod sleeve 62 passes. A pressure sensing element 301 is provided in the installation groove 32.

[0041] Since each sliding rod 61 passes through a sliding hole 31, the carrier 30 can move relative to multiple sliding rods 61 during movement. The presence of multiple sliding rods 61 ensures the stability of the carrier 30 during movement, preventing potential swaying. Furthermore, a mounting groove 32 is provided on the wall of the sliding hole 31 through which the sliding rod sleeve 62 passes. A pressure sensor 301 is installed in the mounting groove 32, facilitating easy installation of the pressure sensor 301 on the carrier 30 and ensuring stable contact between the pressure sensor 301 and the inclined surface of the sliding rod sleeve 62.

[0042] It should be noted that a first conductive element can be provided in the sliding hole 31, and a second conductive element can be provided in the carrier 30. The second conductive element is electrically connected to the coil assembly 40 and the pressure sensor 301 respectively. The first conductive element is in contact with the sliding rod 61, so that the sliding rod 61 can transfer electrical energy to the first conductive element. The first conductive element transfers electrical energy to the coil assembly 40 and the pressure sensor 301 through the second conductive element.

[0043] Additionally, in some embodiments, such as Figure 7 As shown, the pressure sensor 301 has a deformable end 3011, which is deformable and abuts against an inclined surface.

[0044] Since the deformable end 3011 abuts against the inclined surface, during the process of the bearing 30 driving the pressure sensor 301 to move, the deformable end 3011 abuts against the inclined surface at different positions. Therefore, the deformation of the deformable end 3011 will be different at different positions of the inclined surface, that is, the force on the deformable end 3011 will be different. Thus, the position of the pressure sensor 301 can be determined based on the different deformation of the deformable end 3011.

[0045] It should be noted that the correspondence between the deformation of the deformable end 3011 and the position of the inclined surface can be stored in advance. Therefore, once the deformation of the deformable end 3011 is determined, the position of the inclined surface can be determined based on the correspondence. For example, the correspondence is as follows: position A on the inclined surface corresponds to deformation 1, position B on the inclined surface corresponds to deformation 2, and position C on the inclined surface corresponds to deformation 3. Thus, as the pressure sensor 301 moves with the carrier 30, if the deformation of the deformable end 3011 of the pressure sensor 301 is determined to be 3, it can be determined that the deformable end 3011 is located at position C.

[0046] Additionally, in some embodiments, such as Figure 3 As shown, a groove 33 may be provided on the outer wall of the carrier 30, and a fixing post 34 is fixed at the bottom of the groove 33. The coil assembly 40 is sleeved on the fixing post 34 so that the coil assembly 40 is fixed to the carrier 30.

[0047] Since a groove 33 can be provided on the outer wall of the carrier 30, and a fixing post 34 is fixed at the bottom of the groove 33, the coil assembly 40 can be directly sleeved on the fixing post 34, thereby fixing the coil assembly 40 to the carrier 30. Furthermore, the presence of the groove 33 prevents the coil assembly 40 from protruding from the carrier 30, thus avoiding an increase in the required cavity space and consequently an increase in the size of the housing 10. In other words, by providing a groove 33 on the outer wall of the carrier 30, the size of the motor can be reduced.

[0048] It should be noted that when the coil assembly 40 includes multiple conductive coils 41, multiple grooves 33 can be provided on the outer wall of the carrier 30. Furthermore, the number of fixing posts 34 in each groove 33 can be set according to actual needs; for example, the number of fixing posts 34 in each groove 33 can be two, or in another example, the number of fixing posts 34 in each groove 33 can be three. This embodiment of the present application does not limit this. Additionally, when multiple fixing posts 34 are provided in each groove 33, the conductive coils 41 can be simultaneously fitted onto multiple fixing posts 34.

[0049] Additionally, in some embodiments, such as Figure 1 As shown, the motor may also include a connection terminal 70, which is fixed to the surface of the base 20 away from the housing 10. The connection terminal 70 is used to energize the base 20 so that the base 20 transmits electrical energy to the sliding rod 61, and the sliding rod 61 supplies power to the coil assembly 40.

[0050] Since the connecting terminal 70 is fixed to the surface of the base 20 facing away from the housing 10, it can be directly connected to the energizing device. The energizing device can then transmit electrical energy to the connecting terminal 70, which in turn transmits the energy to the base 20. This allows the base 20 to transmit electrical energy to the sliding rod 61, which in turn supplies power to the coil assembly 40. In other words, by providing the connecting terminal 70, electrical energy can be conveniently transmitted to the base 20 and then to the sliding rod 61.

[0051] It should be noted that the number of connection terminals 70 can be set according to actual needs. For example, the number of connection terminals 70 may be 4, or the number of connection terminals 70 may be 6. The specific number of connection terminals 70 is not limited in this embodiment.

[0052] In some embodiments, the second end of the slide rod assembly 60 is fixedly connected to the inner wall of the housing 10.

[0053] With this configuration, both ends of the slide rod assembly 60 can be fixed, thereby avoiding the problem of the slide rod assembly 60 shaking in the housing 10. This makes it easier for the carrier 30 to move along the slide rod assembly 60, allowing the carrier 30 to slide more stably.

[0054] It should be noted that the second end of the slide rod assembly 60 can be fixedly connected to the inner wall of the housing 10 in one of the following ways: the second end of the slide rod assembly 60 can be glued to the inner wall of the housing 10. Of course, the second end of the slide rod assembly 60 can also be fixedly connected to the inner wall of the housing 10 in other ways, for example, the second end of the slide rod assembly 60 can also be fixed to the inner wall of the housing 10 with screws. This application embodiment does not limit the scope of this method.

[0055] In addition, when the slide rod assembly 60 includes a plurality of slide rods 61, the second end of each slide rod 61 is fixed to the inner wall of the housing 10.

[0056] In this embodiment, since the housing 10 has a receiving cavity and an opening, and the opening communicates with the receiving cavity, and the base 20 blocks the opening, the base 20 and the housing 10 can form a receiving space. This allows the slide rod assembly 60, the carrier 30, the coil assembly 40, and the magnetic assembly 50 to be all disposed within the receiving cavity, thus protecting them. Because the first end of the slide rod assembly 60 is electrically connected to the base 20, and the carrier 30 is slidably connected to the slide rod assembly 60, the carrier 30 can slide relative to the slide rod assembly 60. Therefore, after the lens of the camera module is mounted on the carrier 30, the carrier 30 can move the lens, enabling the camera module to focus. Since the coil assembly 40 is fixed to the carrier 30, the magnetic assembly 50 is fixed to the cavity wall of the receiving cavity, and the magnetic assembly 50 and the coil assembly 40 are positioned opposite each other, and the slide rod assembly 60 is electrically connected to the coil assembly 40, power can be supplied to the coil assembly 40 through the slide rod assembly 60, so that the coil assembly 40 can generate a magnetic field. The interaction between this magnetic field and the magnetic assembly 50 can cause the coil assembly 40 to move the carrier 30, thereby causing the carrier 30 to move the lens assembly and achieve focusing of the camera module. In other words, in this embodiment, by setting the slide rod assembly 60 to be conductive and electrically connected to the coil assembly 40 on the carrier 30, and fixing the magnetic assembly 50 to the inner wall of the receiving cavity of the housing 10, the coil assembly 40 is movable and the magnetic assembly 50 is fixed. Power is supplied to the coil assembly 40 through the slide rod assembly 60, which enables the coil assembly 40 to drive the carrier 30 to move, and the carrier 30 to drive the lens to move, thereby enabling the camera module to focus. In addition, the coil assembly 40 is fixed on the carrier 30, and the magnetic assembly 50 is fixed to the cavity wall of the receiving cavity. The coil assembly 40 has a small response to external magnetic fields, that is, the external magnetic field has a small impact on the coil assembly 40, which makes the motor less affected by the external magnetic field, and thus the camera module less affected by the external magnetic field.
