[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 sliding rod assembly 60 .

[0024] The shell 10 has a accommodating cavity and an opening, the opening is connected to the accommodating cavity, the base 20 blocks the opening, the slide bar assembly 60, the carrier 30, the coil assembly 40 and the magnetic assembly 50 are all located in the accommodating cavity; the first end of the slide bar assembly 60 is electrically connected to the base 20, the carrier 30 is slidably connected to the slide bar assembly 60, the carrier 30 is used to carry 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 accommodating cavity, and the magnetic assembly 50 is positioned opposite to the coil assembly 40, the slide bar assembly 60 is electrically connected to the coil assembly 40, and the slide bar 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 bar assembly 60.

[0025] In the embodiment of the present application, since the housing 10 has a receiving cavity and an opening, the opening is connected to the receiving cavity, and the base 20 blocks the opening, the base 20 and the housing 10 can form a receiving space, so that the slide bar assembly 60, the carrier 30, the coil assembly 40 and the magnetic assembly 50 can be arranged in the receiving cavity, that is, the slide bar assembly 60, the carrier 30, the coil assembly 40 and the magnetic assembly 50 are all arranged in the receiving space, and the housing 10 can protect the slide bar assembly 60, the carrier 30, the coil assembly 40 and the magnetic assembly 50. Since the first end of the slide bar assembly 60 is electrically connected to the base 20, and the carrier 30 is slidably connected to the slide bar assembly 60, the carrier 30 can slide relative to the slide bar assembly 60, so that after the lens of the camera module is installed on the carrier 30, the carrier 30 can drive the lens to move, so that the camera module is focused. Since the coil assembly 40 is fixed to the carrier 30, the magnetic assembly 50 is fixed to the cavity wall of the accommodating cavity, and the magnetic assembly 50 is positioned opposite to the coil assembly 40, and the slide assembly 60 is electrically connected to the coil assembly 40, power can be supplied to the coil assembly 40 through the slide assembly 60, so that the coil assembly 40 can generate a magnetic field. The interaction of the magnetic field with the magnetic assembly 50 can enable the coil assembly 40 to drive the carrier 30 to move, and the carrier 30 drives the lens assembly to move, thereby realizing the focusing of the camera module. That is, in the embodiment of the present application, the slide rod assembly 60 is configured to be conductive, and the slide rod assembly 60 is electrically connected to the coil assembly 40 on the carrier 30, and the magnetic assembly 50 is fixed on the inner wall of the accommodating cavity of the shell 10, so that the coil assembly 40 is movable, the magnetic assembly 50 is fixed, and power is supplied to the coil assembly 40 through the slide rod assembly 60, so that the coil assembly 40 can drive the carrier 30 to move, and the carrier 30 can drive the lens to move, so as to achieve the focusing of the camera module. In addition, the coil assembly 40 is fixed on the carrier 30, and the magnetic assembly 50 is fixed on the cavity wall of the accommodating cavity, and the coil assembly 40 reacts less to the external magnetic field, that is, the external magnetic field has less influence on the coil assembly 40, so that the motor is less affected by the external magnetic field, and then the camera module is less affected by the external magnetic field.

[0026] It should be noted that in the embodiment of the present application, the coil assembly 40 may include a plurality of conductive coils 41, the magnetic assembly 50 may include a plurality of magnets 51, the plurality of conductive coils 41 may be fixed on the outer wall of the carrier 30 at intervals along the circumferential direction of the carrier 30, the plurality of magnets 51 may be fixed on the cavity wall of the accommodating cavity along the circumferential direction of the carrier 30, and one conductive coil 41 corresponds to one magnet 51 in position, and the plurality of conductive coils 41 may be electrically connected to the slide bar assembly 60, so that once the slide bar 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 to the outer wall of the carrier 30 at intervals along the circumferential direction of the carrier 30, and the four magnets 51 are fixed to the cavity wall of the accommodating cavity along the circumferential direction of the carrier 30. One magnet 51 corresponds to one conductive coil 41, and the four conductive coils 41 are electrically connected to the slide bar assembly 60. For another example, the coil assembly 40 includes six conductive coils 41, and the magnetic assembly 50 includes six magnets 51. The specific number of the conductive coils 41 and the specific number of the magnets 51 are not limited in the embodiment of the present application.

[0028] In addition, in the embodiment of the present application, the material of the slide bar assembly 60 can be formed of a metal material, so that the slide bar assembly 60 is conductive, for example, the slide bar assembly 60 is formed of copper, and for another example, the slide bar assembly 60 is formed of silver. Of course, the slide bar assembly 60 can also be formed of other conductive materials. The specific material of the slide bar assembly 60 is not limited in the embodiment of the present application.

[0029] In addition, in the embodiment of the present application, the base 20 can be a circuit board. Of course, the base 20 can also be formed of a conductive material. This embodiment of the present application is not limited here. In addition, the first end of the slide bar assembly 60 can be welded to the base 20, so that the slide bar assembly 60 is electrically connected to the base 20, so that the base 20 can transfer electrical energy to the slide bar assembly 60.

[0030] In addition, in some embodiments, Figure 1 As shown, the slide rod assembly 60 may include a plurality of slide rods 61, each of which is conductive, a 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, at least one slide rod 61 is sleeved with a slide rod sleeve 62, 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 sliding rod assembly 60 may include a plurality of sliding rods 61, and each sliding rod 61 is slidably connected to the carrier 30, the carrier 30 may move along the plurality of sliding rods 61 during the movement of the carrier 30, thereby making the movement of the carrier 30 more stable. Since each sliding rod 61 is conductive, the first end of each sliding rod 61 is electrically connected to the base 20, and at least one sliding rod 61 is electrically connected to the coil assembly 40, the coil assembly 40 may be powered by the sliding rod 61 electrically connected to the coil assembly 40, so that the coil assembly 40 drives the carrier 30 to move, and then the carrier 30 drives the lens to move. Since at least one sliding rod 61 is provided with a sliding rod sleeve 62, 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 carrier 30, and 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 carrier 30 to move, and the carrier 30 can drive the pressure sensor 301 to move, and the pressure sensor 301 abuts against the inclined surface on the sliding rod sleeve 62, so that during the movement of the pressure sensor 301, the pressure on the pressure sensor 301 at different positions of the inclined surface is different, so that the specific position of the pressure sensor 301 can be determined according to the different forces on the pressure sensor 301, and then the specific position of the carrier 30 is determined, so that the position of the lens can be accurately determined, so that the position of the lens can be accurately determined during the focusing process of the camera module, which is convenient for focusing the camera module. That is, in the embodiment of the present application, by providing an inclined surface on the slide rod sleeve 62, it is helpful to accurately determine the position of the carrier 30 when the carrier 30 drives the pressure sensor 301 to move, and then accurately determine the position of the lens.

[0032] It should be noted that, in the embodiment of the present application, the pressure sensing element 301 may be a pressure sensor.

[0033] In addition, in the embodiment of the present application, the slide rod sleeve 62 can be fixed on the slide rod 61, so as to avoid the problem that the pressure sensor 301 drives the slide rod sleeve 62 to move when the carrier 30 drives the pressure sensor 301 to move.

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

[0035] In addition, in the embodiment of the present application, the slide rod sleeve 62 may be a tapered sleeve, and the outer surface of the slide rod sleeve 62 forms an inclined surface. Since the slide rod sleeve 62 is a tapered sleeve, the outer surface of the tapered sleeve can directly form an inclined surface, thereby ensuring that the pressure sensor 301 is subjected to different pressures when the pressure sensor 301 moves along the axial direction of the slide rod 61. That is, by setting the slide rod 61 as a tapered sleeve, it is convenient to set an inclined surface on the slide rod sleeve 62, thereby facilitating the pressure sensor 301 to be subjected to different pressures.

[0036] Of course, in the embodiment of the present application, a slide groove may be provided on the outer wall of the slide rod sleeve 62 along the axial direction of the slide rod sleeve 62, and the groove bottom of the slide groove is inclined, so that the groove bottom of the slide groove forms an inclined surface. A boss may also be provided on the outer wall of the slide rod sleeve 62 along the axial direction of the slide rod sleeve 62, and the surface of the boss away from the slide rod sleeve 62 is inclined along the axial direction of the slide rod sleeve 62, so that the surface of the boss away from the slide rod sleeve 62 forms an inclined surface. The embodiment of the present application does not limit the manner in which the slide rod sleeve 62 is provided with the inclined surface.

[0037] In addition, in some embodiments, the pressure sensor 301 is electrically connected to the sliding rod 61 which is not covered with the sliding rod cover 62 .

[0038] Through such a configuration, the sliding rod 61 can simultaneously power the coil assembly 40 and the pressure sensor 301 , avoiding the use of other additional methods to power the pressure sensor 301 , thereby reducing costs.

[0039] It should be noted that a wire or a conductive part can be set in the carrier 30, and the conductive part or the wire is electrically connected to the pressure sensor 301 and the coil assembly 40, and the sliding rod 61 is connected to the conductive part or the conductive part, so that the sliding rod 61 can simultaneously supply power to the coil assembly 40 and the pressure sensor 301.

[0040] In addition, in some embodiments, Figure 2 As shown, a plurality of sliding holes 31 may be provided on the carrier 30, and the sliding holes 31 penetrate the carrier 30 along the sliding direction of the carrier 30, and a sliding rod 61 is passed 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, and a pressure sensor 301 is provided in the installation groove 32.

[0041] Since one sliding rod 61 passes through one sliding hole 31, the carrier 30 can move relative to the multiple sliding rods 61 during the movement of the carrier 30. Therefore, the presence of multiple sliding rods 61 can make the carrier 30 relatively stable during the movement, avoiding the problem of the carrier 30 shaking during the movement. In addition, a mounting groove 32 is provided on the hole wall of the sliding hole 31 through which the sliding rod sleeve 62 passes, and a pressure sensor 301 is provided in the mounting groove 32, so that the pressure sensor 301 can be easily installed on the carrier 30 and ensure that the pressure sensor 301 is relatively stably abutted against the inclined surface of the sliding rod sleeve 62.

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

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

[0044] Since the deformation end 3011 abuts against the inclined surface, during the process of the carrier 30 driving the pressure sensor 301 to move, the deformation end 3011 abuts against different positions of the inclined surface, so that different positions of the inclined surface will cause different deformations of the deformation end 3011, that is, the deformation end 3011 is subjected to different forces, so that the moving position of the pressure sensor 301 can be determined according to the different deformation amounts of the deformation end 3011.

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

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

[0047] Since the outer wall of the carrier 30 may be provided with a groove 33, and the bottom of the groove 33 is fixed with a fixing column 34, the coil assembly 40 can be directly sleeved on the fixing column 34, so that the coil assembly 40 is fixed on the carrier 30. The existence of the groove 33 prevents the coil assembly 40 from protruding from the carrier 30, resulting in an increase in the space of the required accommodation cavity, and further resulting in an increase in the size of the housing 10. That is, by providing the groove 33 on the outer wall of the carrier 30, it is helpful to reduce the size of the motor.

[0048] It should be noted that when the coil assembly 40 includes a plurality of conductive coils 41, a plurality of grooves 33 may be provided on the outer wall of the carrier 30. In addition, the number of fixing posts 34 in each groove 33 may be set according to actual needs, for example, the number of fixing posts 34 in each groove 33 is 2, and in another example, the number of fixing posts 34 in each groove 33 is 3. This is not limited in the embodiments of the present application. In addition, when a plurality of fixing posts 34 are provided in each groove 33, the conductive coil 41 may be simultaneously sleeved on the plurality of fixing posts 34.

[0049] In addition, in some embodiments, Figure 1 As shown, the motor may further include a connection terminal 70 , which is fixed to the surface of the base 20 facing away from the shell 10 , and is used to energize the base 20 so that the base 20 transfers electrical energy to the sliding rod 61 , so that the sliding rod 61 supplies power to the coil assembly 40 .

[0050] Since the connection terminal 70 is fixed to the surface of the base 20 facing away from the housing 10, the connection terminal 70 can be directly connected to the powered device, so that the powered device can transfer electric energy to the connection terminal 70, and the connection terminal 70 transfers the electric energy to the base 20, so that the base 20 transfers the electric energy to the sliding rod 61, and the sliding rod 61 supplies power to the coil assembly 40. That is, by providing the connection terminal 70, the electric energy can be more conveniently transferred to the base 20, and then to the sliding rod 61.

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

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

[0053] Through such a configuration, both ends of the slide bar assembly 60 can be fixed, thereby avoiding the problem of the slide bar assembly 60 shaking in the shell 10, and further facilitating the movement of the carrier 30 along the slide bar assembly 60, so that the carrier 30 can slide more stably.

[0054] It should be noted that the second end of the slide bar assembly 60 can be fixedly connected to the inner wall of the housing 10 in the following manner: the second end of the slide bar assembly 60 can be bonded to the inner wall of the housing 10 by adhesive. Of course, the second end of the slide bar assembly 60 can be fixedly connected to the inner wall of the housing 10 in other manners, for example, the second end of the slide bar assembly 60 can also be fixed to the inner wall of the housing 10 by screws. This is not limited in the embodiments of the present application.

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

[0056] In the embodiment of the present application, since the housing 10 has a receiving cavity and an opening, the opening is connected to the receiving cavity, and the base 20 blocks the opening, the base 20 and the housing 10 can form a receiving space, so that the slide bar assembly 60, the carrier 30, the coil assembly 40 and the magnetic assembly 50 can be arranged in the receiving cavity, that is, the slide bar assembly 60, the carrier 30, the coil assembly 40 and the magnetic assembly 50 are all arranged in the receiving space, and the housing 10 can protect the slide bar assembly 60, the carrier 30, the coil assembly 40 and the magnetic assembly 50. Since the first end of the slide bar assembly 60 is electrically connected to the base 20, and the carrier 30 is slidably connected to the slide bar assembly 60, the carrier 30 can slide relative to the slide bar assembly 60, so that after the lens of the camera module is installed on the carrier 30, the carrier 30 can drive the lens to move, so that the camera module is focused. Since the coil assembly 40 is fixed to the carrier 30, the magnetic assembly 50 is fixed to the cavity wall of the accommodating cavity, and the magnetic assembly 50 is positioned opposite to the coil assembly 40, and the slide assembly 60 is electrically connected to the coil assembly 40, power can be supplied to the coil assembly 40 through the slide assembly 60, so that the coil assembly 40 can generate a magnetic field. The interaction of the magnetic field with the magnetic assembly 50 can enable the coil assembly 40 to drive the carrier 30 to move, and the carrier 30 drives the lens assembly to move, thereby realizing the focusing of the camera module. That is, in the embodiment of the present application, the slide rod assembly 60 is configured to be conductive, and the slide rod assembly 60 is electrically connected to the coil assembly 40 on the carrier 30, and the magnetic assembly 50 is fixed on the inner wall of the accommodating cavity of the shell 10, so that the coil assembly 40 is movable, the magnetic assembly 50 is fixed, and power is supplied to the coil assembly 40 through the slide rod assembly 60, so that the coil assembly 40 can drive the carrier 30 to move, and the carrier 30 can drive the lens to move, so as to achieve the focusing of the camera module. In addition, the coil assembly 40 is fixed on the carrier 30, and the magnetic assembly 50 is fixed on the cavity wall of the accommodating cavity, and the coil assembly 40 reacts less to the external magnetic field, that is, the external magnetic field has less influence on the coil assembly 40, so that the motor is less affected by the external magnetic field, and then the camera module is less affected by the external magnetic field.
