Technical Field
[0001] This application relates to the field of camera equipment technology, specifically to a camera motor, camera module, and electronic equipment. Background Technology
[0002] Hall effect sensors are typically installed in camera motors to improve the control accuracy of the motor. Currently, the Hall effect sensor is usually placed in the middle of the camera motor coil. The width of the coil is limited due to the Hall effect sensor in the middle, which cannot meet the market demand for miniaturization of camera motors. Utility Model Content
[0003] In view of the above, it is necessary to provide a camera motor, camera module, and electronic device to achieve miniaturization.
[0004] This application provides a camera motor, including:
[0005] Base;
[0006] A support base is disposed on the base and forms an installation space between the base and the base;
[0007] Hall element, disposed on the base;
[0008] A circuit board is disposed on the base and electrically connected to the Hall element;
[0009] A coil is disposed in the mounting space; and
[0010] A magnet is disposed on the support base and located in the mounting space, and the Hall element, the coil and the magnet are arranged sequentially at intervals along the axial direction of the coil.
[0011] In the aforementioned camera motor, the Hall element, coil, and magnet are arranged sequentially at intervals along the axial direction of the coil, which can reduce the width of the coil and thus reduce the overall width of the camera motor, thereby achieving a miniaturized design of the camera motor.
[0012] In some embodiments, the Hall element and the coil are respectively disposed on opposite sides of the circuit board.
[0013] Therefore, by adopting the above settings, the installation difficulty of Hall elements and coils can be reduced, thereby reducing the manufacturing cost of camera motors.
[0014] In some embodiments, the base has a receiving groove on its surface facing the coil, and the Hall element is disposed in the receiving groove.
[0015] Therefore, the accommodating slot can store Hall elements, thereby reducing the overall height of the camera motor and facilitating its miniaturization.
[0016] In some embodiments, the circuit board covers the receiving slot, and the coil is disposed on the circuit board.
[0017] Therefore, the circuit board can cover the Hall element located in the receiving slot to ensure the stability of the Hall element relative to the base.
[0018] In some embodiments, the circuit board is located away from the receiving groove, the coil is disposed on the base, and the Hall element includes an element body and a conductive sheet. The element body is disposed on the receiving groove, and the conductive sheet is disposed on the base and electrically connected to the element body and the circuit board respectively.
[0019] Therefore, by electrically connecting the component body and the circuit board with conductive sheets, the overall height of the camera motor can be reduced, which is beneficial for the miniaturization of the camera motor.
[0020] In some embodiments, the conductive sheet is embedded in the base and located between the component body and the coil.
[0021] Therefore, the embedded structure of the conductive sheet and the base can avoid increasing the height of the camera motor, which is beneficial for the miniaturization of the camera motor.
[0022] In some embodiments, the center of the Hall element, the center of the coil, and the center of the magnet are collinear along the axial direction of the coil.
[0023] Therefore, by adopting the above settings, the accuracy of the Hall element's sensing of the magnetic field can be improved, which is beneficial to improving the adjustment precision of the camera motor.
[0024] In some embodiments, the support base includes:
[0025] A bracket is disposed on the base and connected to the magnet;
[0026] A carrier, embedded in the bracket, is used to mount the lens assembly;
[0027] A protective shell is fitted onto the bracket and, together with the bracket and the base, forms the installation space.
[0028] The carrier, the support, and the protective shell are arranged coaxially.
[0029] Therefore, the carrier, support, and protective shell form a structure that is nested in sequence, which can not only improve the overall stability of the camera motor, but also prevent external components from colliding with the magnet and coil.
[0030] This application embodiment also provides a camera module, including:
[0031] The aforementioned camera motor; and
[0032] The lens assembly is mounted on the support.
[0033] In the camera motor of the aforementioned camera module, the Hall element, coil, and magnet are arranged sequentially and spaced apart along the axial direction of the coil, which can reduce the width of the coil and thus reduce the overall width of the camera motor, thereby achieving a miniaturized design of the camera module.

[0035] The aforementioned camera module; and
[0036] Housing, the camera module is mounted on the housing.

[0046] The embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0047] Please see Figure 1 and Figure 2 This application provides a camera motor 100, including a base 110, a support 120, a Hall element 130, a circuit board 140, a coil 150, and a magnet 160. The support 120 is disposed on the base 110 and forms an installation space 100a between the support 120 and the base 110. The Hall element 130 is disposed on the base 110. The circuit board 140 is disposed on the base 110 and electrically connected to the Hall element 130. The coil 150 is disposed in the installation space 100a. The magnet 160 is disposed on the support 120 and located in the installation space 100a. The Hall element 130, the coil 150, and the magnet 160 are sequentially spaced along the axial direction of the coil 150. Exemplarily, the magnet 160 can be a magnet or a magnetic stone.
[0048] In the aforementioned camera motor 100, the Hall element 130, coil 150, and magnet 160 are arranged sequentially at intervals along the axial direction of the coil 150, which can reduce the width of the coil 150, thereby reducing the overall width of the camera motor 100 and achieving a miniaturized design of the camera motor 100.
[0049] It should be noted that in this embodiment, both the support base 120 and the base 110 are generally hollow cuboids. Multiple Hall elements 130, coils 150, and magnets 160 can be used. These multiple Hall elements 130, coils 150, and magnets 160 are spaced apart circumferentially along the support base 120 and correspond one-to-one. The circuit board 140 is generally annular to be electrically connected to each of the multiple Hall elements 130. The Hall elements 130, coils 150, and magnets 160 will be described individually below.
[0050] Please see Figure 2 In some embodiments, the Hall element 130 and the coil 150 are respectively disposed on opposite sides of the circuit board 140.
[0051] Therefore, the above-mentioned setup can reduce the installation difficulty of Hall element 130 and coil 150, thereby reducing the manufacturing cost of camera motor 100.
[0052] Please see Figure 2 In some embodiments, the base 110 has a receiving groove 110a on its surface facing the coil 150, and the Hall element 130 is disposed in the receiving groove 110a.
[0053] Therefore, the receiving slot 110a can store the Hall element 130, thereby reducing the overall height of the camera motor 100 and facilitating the miniaturization of the camera motor 100.
[0054] Please see Figure 2 In some embodiments, the circuit board 140 covers the receiving groove 110a, and the coil 150 is disposed on the circuit board 140.
[0055] Therefore, the circuit board 140 can cover the Hall element 130 located in the receiving groove 110a to ensure the stability of the Hall element 130 relative to the base 110.
[0056] In some embodiments, the center of Hall element 130, the center of coil 150, and the center of magnet 160 are collinear in the axial direction of coil 150.
[0057] Therefore, the above settings can improve the accuracy of the Hall element 130 in sensing the magnetic field, which is beneficial to improving the adjustment accuracy of the camera motor 100.
[0058] Please see Figure 1 and Figure 2 In some embodiments, the support base 120 includes a bracket 121, a carrier 122, and a protective shell 123. The bracket 121 is disposed on the base 110 and connected to the magnet 160. The carrier 122 is embedded in the bracket 121 for mounting the lens assembly. The protective shell 123 is fitted onto the bracket 121 and together with the bracket 121 and the base 110, forms an installation space 100a. The carrier 122, bracket 121, and protective shell 123 are coaxially arranged.
[0059] Therefore, the carrier 122, the bracket 121 and the protective shell 123 form a structure in which they are nested together, which can not only improve the overall stability of the camera motor 100, but also prevent external components from colliding with the magnet 160 and the coil 150.
[0060] Please see Figure 2In some embodiments, the support 121 includes a body 1211 and an adhesive layer 1212. The body 1211 is sleeved on and supports the carrier 122, and the body 1211 is disposed on the base 110. The protective shell 123 is sleeved on the body 1211, and the adhesive layer 1212 connects the body 1211 and the magnet 160 to fix the magnet 160 and the body 1211.
[0061] Therefore, by fixing the main body 1211 and the magnet 160 through the adhesive layer 1212, the manufacturing cost of the camera motor 100 can be reduced.
[0062] Please see Figure 3 In some embodiments, the circuit board 140 is located away from the receiving groove 110a, the coil 150 is disposed on the base 110, and the Hall element 130 includes an element body 131 and a conductive sheet 132. The element body 131 is disposed on the receiving groove 110a, and the conductive sheet 132 is disposed on the base 110 and electrically connected to the element body 131 and the circuit board 140 respectively.
[0063] Therefore, by electrically connecting the component body 131 and the circuit board 140 through the conductive sheet 132, the overall height of the camera motor 100 can be reduced, which is beneficial to the miniaturization of the camera motor 100.
[0064] For example, the conductive sheet 132 is embedded in the base 110 and located between the component body 131 and the coil 150.
[0065] Therefore, the embedded structure of the conductive sheet 132 and the base 110 can prevent the conductive sheet 132 from increasing the height of the camera motor 100, which is beneficial to the miniaturization of the camera motor 100.
[0066] Please see Figure 4 This application embodiment also provides a camera module 200, including a lens assembly 210 and the aforementioned camera motor 100, wherein the lens assembly 210 is mounted on a support base 120.
[0067] In the camera motor 100 of the aforementioned camera module 200, the Hall element 130, the coil 150 and the magnet 160 are arranged sequentially and spaced apart along the axial direction of the coil 150, which can reduce the width of the coil 150, thereby reducing the overall width of the camera motor 100 and achieving a miniaturized design of the camera module 200.
[0068] Please see Figure 5 This application also provides an electronic device 1000, including a housing 300 and the aforementioned camera module 200, wherein the camera module 200 is mounted on the housing 300. For example, the electronic device 1000 may be a mobile phone, tablet, etc.
[0069] The camera module 200 of the aforementioned electronic device 1000 has a low overall width, which is beneficial for achieving a miniaturized design of the electronic device 1000.
