Description

Motors, camera modules and electronic devices

[0001] This application claims priority to Chinese Patent Application No. 202520166353.2, filed on January 23, 2025, entitled "Motor, Camera Module and Electronic Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of shooting equipment technology, and in particular to a motor, camera module and electronic equipment. Background Technology

[0003] [Correction based on Rule 91, January 22, 2026] In daily life, electronic devices such as mobile phones and tablets are equipped with camera modules to facilitate taking photos anytime, anywhere. Currently, the motor in the camera module can drive the lens to focus or stabilize image. The motor usually includes a housing. When the housing is made of metal, the electrostatic discharge of the metal can affect the driving performance of the motor, impacting the user experience.

[0004] [Corrected according to Rule 91, January 22, 2026] Summary of the Invention

[0005] This application provides a motor, a camera module, and an electronic device. This application achieves effective grounding of the motor housing, avoiding the impact of electrostatic discharge from the housing on the motor's performance.

[0006] In a first aspect, embodiments of this application provide a motor. The motor is applied to a camera module. The motor includes a housing, a base, a first reinforcing member, a first circuit board, and a second circuit board; the housing includes a light-incoming side and an opening side disposed opposite to each other, the light-incoming side having a through hole for light to enter the housing; the base is fixed to the opening side; the first reinforcing member includes an embedded part and a connecting part, the embedded part being embedded in the base, and the connecting part being exposed outside the base; the housing is electrically connected to the connecting part, the connecting part is electrically connected to the first circuit board, and the first circuit board is electrically connected to the second circuit board to achieve grounding of the housing.

[0007] This embodiment of the application fully and reasonably utilizes the first reinforcing member of the motor. By setting a connecting part that electrically connects the housing to the first reinforcing member, the connecting part is electrically connected to the first circuit board, and the first circuit board is electrically connected to the second circuit board, thereby grounding the housing and avoiding the impact of electrostatic discharge of the housing on the motor performance. Compared with the solution of setting terminals on the open side of the housing, electroplating nickel on the terminals, and fixing the nickel-plated terminals to the second circuit board by soldering to achieve the grounding of the housing (the nickel plating on the terminals on the housing will cause magnetic interference to the motor, affecting the motor performance), in this embodiment, the metal housing and the metal first reinforcing member can be welded, avoiding the need for nickel plating on the housing and avoiding magnetic interference to the motor. In addition, the solution of setting terminals on the open side of the housing to electrically connect to the second circuit board requires setting a separate grounding point for the housing on the second circuit board. This embodiment of the application utilizes the grounding path between the first circuit board and the second circuit board, avoiding the need to set a separate grounding point for the housing on the second circuit board, freeing up space on the second circuit board, which is conducive to the miniaturization of the second circuit board and makes full use of the space of the second circuit board.

[0008] In one possible implementation, the base includes a first side and a second side disposed opposite to each other, the first side facing the through hole and the second side facing away from the through hole, at least a portion of the first circuit board being fixed to the first side and at least a portion of the second circuit board being fixed to the second side. This embodiment of the application allows for a reasonable layout of the positions of the first and second circuit boards by positioning them on opposite sides of the base.

[0009] In one possible implementation, the motor includes an image stabilization drive mechanism, an image stabilization bracket, a focusing bracket, and a focusing drive mechanism located within the housing. The image stabilization bracket is movably connected to the base, and the focusing bracket is movably connected to the image stabilization bracket. The image stabilization bracket is used to fix a first lens, and the focusing bracket is used to fix a second lens. The image stabilization drive mechanism is used to drive the image stabilization bracket to move the first lens, the focusing bracket, and the second lens relative to the base along a first direction and / or a second direction. The focusing drive mechanism is used to drive the focusing bracket to move the second lens relative to the image stabilization bracket along a third direction, so that the second lens moves closer to or further away from the first lens, wherein the first direction, the second direction, and the third direction are different from each other.

[0010] Understandably, the camera module may include a first lens and a second lens. A motor can control the movement of the first and second lenses along a first and / or second direction to achieve image stabilization. Thus, when the camera module captures ambient light, if the electronic device shakes in the first and / or second direction due to external forces, the motor can control the movement of the first and second lenses in the first and / or second direction to counteract the shake, thereby avoiding or reducing positional offset caused by the shake. In other words, the camera module of this application can control the movement of the first and second lenses in the first and / or second direction via a motor to achieve optical image stabilization and improve the imaging quality of the camera module. Furthermore, the motor can also control the movement of the second lens along a third direction to achieve autofocus.

[0011] Understandably, when the camera module is working, the first lens remains stationary in the third direction, while the second lens moves along the third direction to achieve autofocus. This reasonable structural design of the camera module means that the distance the second lens moves along the third direction is the focusing stroke of the camera module. Because the second lens's movement distance is small, the focusing stroke of the camera module is also small, and the space requirement in the third direction is also small, allowing for a miniaturized camera module design. By grouping the first and second lenses, image swirl issues related to image stabilization in the camera module can be avoided, resulting in a better focusing experience for the user.

[0012] In one possible implementation, the motor includes a third circuit board, a pressure member, a second reinforcing member, and a bonding member. At least a portion of the pressure member is located on the side of the image stabilization bracket facing away from the base, and the pressure member is used to limit the movement stroke of the focusing bracket in the third direction. A portion of the second reinforcing member is embedded in the image stabilization bracket, and another portion of the second reinforcing member is an exposed portion, which is exposed outside the image stabilization bracket. The third circuit board is fixed to the image stabilization bracket, and the bonding member is located on the side of the third circuit board facing away from the image stabilization bracket. The bonding member is fixedly connected to the pressure member and the exposed portion. This embodiment of the application makes full use of the bonding member. By setting the bonding member to be fixedly connected to the pressure member and the second reinforcing member, the third circuit board is located in the space formed by the image stabilization bracket, the bonding member, the pressure member, and the second reinforcing member, which improves the connection reliability between the third circuit board and the image stabilization bracket and the bonding member, and effectively enhances the firmness.

[0013] In one possible implementation, the focusing drive mechanism includes a focusing coil and a focusing magnetic component. The focusing coil is fixed to the image stabilization bracket, and the focusing magnetic component is fixed to the focusing bracket. The focusing coil faces the focusing magnetic component and is used to drive the focusing bracket to move relative to the image stabilization bracket in a third direction. The motor includes a third circuit board and an electrical connector. The third circuit board is fixed to the image stabilization bracket, and the electrical connector electrically connects the focusing coil and the third circuit board. This embodiment achieves electrical connection between the focusing coil and the third circuit board by using an electrical connector, resulting in high flexibility in the electrical connection.

[0014] In one possible implementation, the motor includes a third circuit board, a bonding component, and a heat-fitting component. The third circuit board is fixed to the anti-shake bracket, the bonding component is located on the side of the third circuit board facing away from the anti-shake bracket, and the heat-fitting component passes through the bonding component and the third circuit board in sequence and is fixedly connected to the anti-shake bracket. This embodiment of the application, by providing a heat-fitting component, can fix the third circuit board and the bonding component to the anti-shake bracket, which helps to improve the connection reliability between the third circuit board and the bonding component and the anti-shake bracket.

[0015] In one possible implementation, the first circuit board includes a first segment and a second segment fixedly connected together, with the first segment and the second segment extending in different directions. The motor includes a first coil, a second coil, a first reinforcing member, and a device. The first coil is fixed to the first segment, and the second coil is fixed to the second segment. The first coil and the second coil are located on the same side of the first circuit board. The device is located on opposite sides of the first circuit board and electrically connected to the first circuit board. The device is located at the connection between the first segment and the second segment. The first reinforcing member connects the first coil and the second coil. Because the first circuit board is thin and lacks sufficient strength, it is prone to deformation during drops or collisions, causing the solder joints connecting the device and the first circuit board to crack, affecting the reliability of the electrical connection and thus the device's function. This embodiment addresses this by providing a first reinforcing member to connect the first coil and the second coil as a single unit. This integrated structure of the first coil, the second coil, and the first reinforcing member has high structural strength, increasing the structural strength of the first circuit board and preventing poor electrical connection reliability caused by deformation of the first circuit board during drops or collisions.

[0016] In one possible implementation, the motor includes a component and a second reinforcing member. The component is fixed to and electrically connected to the first circuit board, and the second reinforcing member is located on the side of the component and fixed to the first circuit board. This embodiment of the application uses a second reinforcing member to increase the structural strength of the first circuit board, preventing deformation of the first circuit board during drops or collisions that could lead to poor electrical connection reliability between the component and the first circuit board.

[0017] In one possible implementation, the number of the second reinforcing members is at least two, and the motor includes the third reinforcing member. The third reinforcing member is located on the side of the device facing away from the first circuit board and is fixedly connected to at least two of the second reinforcing members. This embodiment of the application, by providing a third reinforcing member, significantly increases the structural strength of the first circuit board, avoiding the problem of poor electrical connection reliability between the device and the first circuit board caused by deformation of the first circuit board during drops or collisions. The third reinforcing member and the second reinforcing member can be an integrally formed structure, or they can be separate structures assembled and fixed into an integral structure.

[0018] In one possible implementation, the motor includes a focusing bracket, a focusing coil, a focusing magnetic component, and a focusing sensor. The focusing bracket is located within the housing, the focusing coil is fixed within the housing, the focusing magnetic component is fixed to the focusing bracket, the focusing coil faces the focusing magnetic component, and is used to drive the focusing bracket to move. The focusing sensor is located outside the focusing coil. This embodiment of the application, by placing the focusing sensor outside the focusing coil, helps to avoid interference from the electromagnetic field generated when the focusing coil is energized, thereby improving the detection accuracy of the focusing sensor.

[0019] In one possible implementation, the motor includes a magnetic grating fixed to the focusing bracket and facing the focusing sensor, which is a tunnel magnetoresistive sensor. This embodiment of the application, by providing a magnetic grating and using a tunnel magnetoresistive sensor for the focusing sensor, helps to improve the detection accuracy of the focusing sensor.

[0020] In one possible implementation, the motor includes a focusing bracket for mounting a second lens. The inner wall of the focusing bracket has a groove containing a colloid. The second lens has a protrusion embedded in the colloid. This embodiment of the application, by providing a groove on the inner wall of the focusing bracket and embedding the protrusion of the second lens in the colloid within the groove, facilitates a reliable connection between the second lens and the focusing bracket, preventing the lens from detaching from the bracket.

[0021] In one possible implementation, the focusing bracket has a notch located on the side of the groove away from the base. This embodiment of the application, by providing a notch, facilitates the injection of adhesive into the groove after the second lens is mounted to the focusing bracket. It is understood that the second lens may include a first cylindrical body and a second cylindrical body connected as one unit. A protrusion is located outside the second cylindrical body. The first cylindrical body is located on the side of the second cylindrical body away from the base, the second cylindrical body is located inside the focusing bracket, and the first cylindrical body is located outside the focusing bracket, overlapping the surface of the focusing bracket opposite to the base. Typically, adhesive can be injected into the groove using a needle. After the second lens is mounted to the focusing bracket, the first cylindrical body overlaps the focusing bracket. Without the notch, it would be difficult to insert the needle between the second lens and the focusing bracket, making adhesive dispensing impossible.

[0022] In one possible implementation, the motor includes a first sensor and a third sensor, and the motor is used to mount a first lens. The first sensor and the third sensor are located on the same side of the first lens. This embodiment of the application, by positioning the first sensor and the third sensor on the same side of the first lens, and using the first and third sensors to detect movement of the first lens in the same direction, helps improve the accuracy of the first lens's movement direction. If the detection data from the first sensor and the third sensor are consistent, the first lens is moving in a preset direction to achieve precise image stabilization. If the detection data from the first sensor and the third sensor are different, the first lens has experienced a positional shift during movement. This can be compensated for by adjusting the current in the coil, so that the first lens can move in the preset direction to achieve precise image stabilization.

[0023] Secondly, this application provides a camera module, including a lens and a motor as described in any of the foregoing embodiments, wherein the lens is mounted on the motor.

[0024] Thirdly, this application provides an electronic device, including a housing and a camera module as described in any of the foregoing embodiments, wherein the camera module is disposed within the housing. Attached Figure Description

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] It should be understood that the terms "first," "second," etc., used in this application are for distinguishing purposes only and should not be construed as indicating or implying relative importance or order.

[0051] In the description of this application, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0052] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly, for example, it can be a fixed connection, a detachable connection, a mating connection, or an integral connection; those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0053] As shown in Figure 1, Figure 1 is a structural schematic diagram of an electronic device 1000 provided in an embodiment of this application. The electronic device 1000 can be a mobile phone, tablet computer, laptop computer, in-vehicle device, wearable device, or other device with photography or video recording functions. This application describes the electronic device 1000 as a mobile phone as an example. The electronic device 1000 may include at least one camera module 100.

[0054] Electronic device 1000 may include a housing 200 and a camera module 100. The camera module 100 is located inside the housing 200. The camera module 100 may be disposed on the back of the electronic device 1000, serving as a rear-facing camera. In other embodiments, the camera module 100 may also be disposed on the front of the electronic device 1000, serving as a front-facing camera. Both the front and rear cameras can be used for selfies or for the photographer to capture images of other objects.

[0055] For example, the housing 200 may have a light-transmitting portion (not shown in FIG1), through which light from the outside of the electronic device 1000 can enter the interior of the electronic device 1000. The camera module 100 can capture the light entering the interior of the electronic device 1000. The light-transmitting portion may be a light-transmitting hole or a transparent portion in the housing 200. The specific structure of the light-transmitting portion is not specifically limited in this application.

[0056] It is understood that the installation position of the camera module 100 in the electronic device 1000 of the embodiment shown in Figure 1 is merely illustrative, and this application does not strictly limit the installation position of the camera module 100. In some other embodiments, the camera module 100 may also be installed in other positions of the electronic device 1000, such as the upper middle or upper right corner of the electronic device 1000. Alternatively, the camera module 100 may not be mounted on the main body of the phone, but on an auxiliary component that is movable or rotatable relative to the phone, such as an auxiliary component that can extend, retract, or rotate from the main body of the phone.

[0057] The interior of the casing 200 of the electronic device 1000 can also be used to house components of the electronic device 1000, such as a motherboard, battery, receiver, or microphone.

[0058] The electronic device 1000 in Figure 1 is only schematic; the size, shape, and structure of the electronic device 1000 can be set as needed. This application does not limit the specific structure of the electronic device 1000.

[0059] As shown in Figures 2 and 3, Figure 2 is a schematic diagram of the camera module 100 of the electronic device 1000 shown in Figure 1 in one embodiment, and Figure 3 is a cross-sectional view of the camera module 100 shown in Figure 2 at point AA.

[0060] It is understood that, for ease of description, the camera module 100 is defined in the following text as having a first direction X, a second direction Y, and a third direction Z, which are different from each other. For example, the first direction X is the length direction of the camera module 100, the second direction Y is the width direction of the camera module 100, the second direction Y is perpendicular to the first direction X, and the third direction Z can be the height direction of the camera module 100, which is perpendicular to both the first direction X and the second direction Y. In other embodiments, the coordinate system of the camera module 100 can be flexibly set according to specific actual needs.

[0061] The camera module 100 may include a motor 1 and a lens. The number of lenses may be one, two, or three, etc., and this application embodiment does not limit the number of lenses. When there are two lenses, the two lenses are a first lens 2 and a second lens 3.

[0062] The first lens 2 and the second lens 3 can be mounted on the motor 1. The motor 1 can control the movement of the first lens 2 and the second lens 3 along a plane perpendicular to the third direction Z (i.e., the XY plane) to achieve image stabilization. Thus, when the camera module 100 collects ambient light, if the electronic device 1000 experiences shaking in the XY plane due to external forces, the movement of the first lens 2 and the second lens 3 in the XY plane can be controlled by the motor 1 to counteract the shaking travel of the first lens 2 and the second lens 3, thereby avoiding or reducing the positional offset of the first lens 2 and the second lens 3 caused by shaking. In other words, the camera module 100 of this application can control the movement of the first lens 2 and the second lens 3 in the XY plane by controlling the motor 1, achieving optical image stabilization (OIS) of the camera module 100 and improving the imaging quality of the camera module 100.

[0063] Furthermore, motor 1 can also control the second lens 3 to move along the third direction Z to achieve autofocus (AF). Understandably, motor 1 can also simultaneously control the first lens 2 and the second lens 3 to move along the third direction Z to achieve autofocus.

[0064] Understandably, when the camera module 100 is working, the first lens 2 remains stationary in the third direction Z, while the second lens 3 moves along the third direction Z to achieve autofocus. The structural design of the camera module 100 is quite reasonable. Thus, the movement distance of the second lens 3 along the third direction Z is the focusing stroke of the camera module 100. Because the movement distance of the second lens 3 is small, the focusing stroke of the camera module 100 is also small, and the space requirement of the camera module in the third direction Z is also small, enabling a miniaturized design of the camera module 100. By grouping the first lens 2 and the second lens 3, the image rotation problem of the camera module 100 can be avoided, resulting in a better focusing experience for the user.

[0065] Understandably, the camera module 100 may also include more structures. For example, the camera module 100 may also include a prism 4 and an image sensor 5. The image sensor 5 may be fixed to the side of the first plate portion 151 of the second circuit board 15 facing the third plate portion 153 and electrically connected to the second circuit board 15. In this case, the image sensor 5 and the second circuit board 15 can transmit signals to each other. In other embodiments, the position of the image sensor 5 fixed to the second circuit board 15 is not specifically limited. A portion of the prism 4 is located below the first lens 2, and another portion of the prism 4 may be located between the first plate portion 151 and the third plate portion 153. The specific structure of the second circuit board 15 is described later.

[0066] For example, light enters the camera module 100 from the light-transmitting part of the electronic device 1000, passes through the second lens 3, the first lens 2, and the prism 4 in sequence, and then reaches the image sensor 5. The image sensor 5 converts the image information carried by the light into an electrical signal.

[0067] As shown in Figures 4, 5 and 6, Figure 4 is an exploded view of a motor 1 of the camera module 100 shown in Figure 2, Figure 5 is an exploded view of a portion of the structure of the motor 1 shown in Figure 4, and Figure 6 is an exploded view of a portion of the structure of the motor shown in Figure 5.

[0068] The motor 1 may include a main body 10 and a second circuit board 15. The main body 10 may include a housing 11, a base 12, a first reinforcing member 13, and a first circuit board 14.

[0069] The housing 11 may include a light-inlet side 111 and an opening side 112 disposed opposite to each other. The light-inlet side 111 is provided with a through hole 113 for light to enter the housing 11. The housing 11 may be made of metal or a portion thereof may be made of metal. A metal housing 11 has high structural strength and can provide better protection for the internal structural components.

[0070] The base 12 can be fixed to the opening side 112. The base 12 can be adapted to the shape of the housing 11, and the housing 11 can be placed on the base 12. The housing 11 and the base 12 can be assembled and fitted together to encapsulate and protect the internal structure of the motor 1. Exemplarily, the base 12 and the housing 11 form a receiving cavity 101, which is used to install the internal structural components and lens of the motor 1. The base 12 may include a first side 121 and a second side 122 disposed opposite to each other, the first side 121 facing the through hole 113 and the second side 122 facing away from the through hole 113. The base 12 can be made of plastic, which is lightweight and beneficial to the weight reduction of the motor 1. The base 12 can also be made of other materials, which is not limited in this embodiment.

[0071] The first reinforcing member 13 may include an embedding portion 131, a connecting portion 132, and a first connecting portion 133. The embedding portion 131 is embedded in the base 12, and the connecting portion 132 and the first connecting portion 133 are exposed outside the base 12. Exemplarily, the base 12 may have a first connecting hole 114 through which the connecting portion 132 passes and is exposed outside the base 12. The number of connecting portions 132 may be one, two, or three, etc. When there are two or more connecting portions 132, the multiple connecting portions 132 may be spaced apart around the embedding portion 131. The number and position of the first connecting holes 114 correspond one-to-one with the connecting portions 132. The base 12 may have a second connecting hole 115 through which the first connecting portion 133 passes and is exposed outside the base 12. The first reinforcing member 13 can be made of metal. The first reinforcing member 13 made of metal has high structural strength. The embedded part 131 of the first reinforcing member 13 is embedded in the base 12, which helps to increase the structural strength of the base 12.

[0072] The embedding part 131, the connecting part 132, and the first connecting part 133 can be an integrally formed structure or a separate structure assembled and fixed to form an integral structure. In other embodiments, the first reinforcing member 13 may not have the first connecting part 133. The first reinforcing member 13 can be embedded into the base 12 during the injection molding process of the base 12.

[0073] At least a portion of the second circuit board 15 is fixed to the second side 122. The second circuit board 15 may include a first plate portion 151, a second plate portion 152, and a third plate portion 153. The first plate portion 151 and the third plate portion 153 are arranged opposite to and spaced apart, and the second plate portion 152 connects the first plate portion 151 and the third plate portion 153. A bracket is provided between the third plate portion 153 and the main body 10, and the third plate portion 153 can be fixed to the second side 122 by the bracket. The third plate portion 153 can also be fixed to the second side 122 by other means. The third plate portion 153 is fixed to the second side 122 so that at least a portion of the second circuit board 15 is fixed to the second side 122. The specific structure of the second circuit board 15 is not limited in the embodiments of this application, and can be set as needed. When the second circuit board 15 has other structures, all of the second circuit board 15 can also be fixed to the second side 122. In other embodiments, the second circuit board 15 may not be fixed to the second side 122.

[0074] At least a portion of the first circuit board 14 is fixed to the first side 121. The first circuit board 14 can be electrically connected to the third board portion 153 to achieve electrical connection between the first circuit board 14 and the second circuit board 15. It is understood that while a portion of the first circuit board 14 is fixed to the first side 121, another portion of the first circuit board 14 can be bent to the side of the base 12 to be electrically connected to the third board portion 153. In other embodiments, all of the first circuit board 14 may be fixed to the first side 121. In other embodiments, the first circuit board 14 may also be fixed to other locations.

[0075] The housing 11 can be electrically connected to the connecting part 132, the connecting part 132 is electrically connected to the first circuit board 14, and the first circuit board 14 is electrically connected to the second circuit board 15, so as to ground the housing 11.

[0076] For example, the housing 11 is welded to the connecting part 132 to achieve an electrical connection between the housing 11 and the connecting part 132. The housing 11 and the connecting part 132 can be connected by laser welding, or other connection methods can be used to achieve an electrical connection. Understandably, other parts of the housing 11 that are not welded to the connecting part 132 can be fixedly connected to the base 12 by means of adhesive dispensing or other methods.

[0077] For example, the connecting portion 132 can be electrically connected to the first circuit board 14 via the first connecting portion 133. The connecting portion 132 is electrically connected to the embedded portion 131, the embedded portion 131 is electrically connected to the first connecting portion 133, and the first connecting portion 133 is electrically connected to the first circuit board 14, thereby realizing the electrical connection of the connecting portion 132 to the first circuit board 14. After the first connecting portion 133 is nickel-plated, it can be electrically connected to the first circuit board 14 by soldering.

[0078] Understandably, when the housing 11 is made of metal, or when a portion of the housing 11 is made of metal, electrostatic discharge from the metal can affect the driving performance of the motor 1. For example, a metal housing 11 can affect the functionality of the drive chip and position sensors, thus impacting motor performance. Therefore, the housing 11 needs to be grounded.

[0079] This application embodiment makes full and reasonable use of the first reinforcing member 13 of the motor 1. By setting the housing 11 to be electrically connected to the connecting part 132 of the first reinforcing member 13, the connecting part 132 to be electrically connected to the first circuit board 14, and the first circuit board 14 to be electrically connected to the second circuit board 15, the housing 11 is electrically connected to the second circuit board 15, thereby grounding the housing 11 and avoiding the impact of electrostatic discharge of the housing 11 on the performance of the motor 1.

[0080] Compared to the solution of setting terminals on the open side of the housing 11, electroplating nickel on the terminals, and soldering the nickel-plated terminals to the second circuit board to achieve grounding of the housing 11 (where nickel plating on the terminals of the housing 11 would cause magnetic interference to the motor, affecting motor performance), in this embodiment, the metal housing 11 and the metal first reinforcing member 13 can be welded, avoiding nickel plating on the housing 11 and avoiding magnetic interference to the motor 1. Furthermore, the solution of setting terminals on the open side of the housing 11 to electrically connect to the second circuit board requires setting a separate grounding point for the housing 11 on the second circuit board, which occupies space on the second circuit board 15. This embodiment utilizes the grounding path between the first circuit board 14 and the second circuit board 15, avoiding setting a separate grounding point for the housing 11 on the second circuit board 15, freeing up space on the second circuit board 15, which is beneficial for miniaturization of the second circuit board 15 and makes full use of its space.

[0081] Understandably, during the process of motor 1 driving the lens to achieve image stabilization, the lens has degrees of freedom in the first direction X and the second direction Y, but no degree of freedom in the third direction Z. Therefore, the magnetic attraction in the first direction X and the second direction Y will interfere with the motor, while the magnetic attraction in the third direction Z will not interfere with motor 1. After the terminals on the housing 11 are electroplated with nickel, the magnetic attraction generated by them and the first magnetic component 162 and the second magnetic component 164 (descriptions of the first magnetic component 162 and the second magnetic component 164 are provided below) is along the first direction X and the second direction Y, so it will interfere with the motor performance. In this embodiment, after the first connecting portion 133 of the first reinforcing member 13 is electroplated with nickel, the magnetic attraction generated by it and the first magnetic component 162 and the second magnetic component 164 is along the third direction Z, so it will not interfere with the motor performance.

[0082] As shown in Figures 7 to 11, Figure 7 is an exploded structural diagram of the main body 10 of the motor 1 shown in Figure 4; Figure 8 is a structural diagram of the assembled structure shown in Figure 7; Figure 9 is a structural diagram of the assembled structure shown in Figure 8; Figure 10 is a cross-sectional view of the main body 10 of the motor 1 shown in Figure 4 along BB; and Figure 11 is a cross-sectional view of the main body 10 of the motor 1 shown in Figure 4 along CC. It is understood that the assembly order of the multiple structural components in the motor 1 is not limited in the embodiments of this application, and they can be assembled as needed. The motor 1 may include a bracket, which can be a focusing bracket 18 or an image stabilization bracket 17. The focusing bracket 18 can be used to mount a second lens, and the image stabilization bracket 17 can be used to mount a first lens.

[0083] The motor 1 may include a stabilization drive mechanism 16 and a stabilization bracket 17.

Image stabilization drive mechanism 16 may include the first coil 161, first magnetic element 162, second coil 163, and second magnetic element 164 for image stabilization. Specifically, the first coil 161 and first magnetic element 162 are correspondingly arranged in the third direction Z to form one drive mechanism, and the second coil 163 and second magnetic element 164 are correspondingly arranged in the third direction Z to form another drive mechanism.

[0085] The first coil 161 is fixed to and electrically connected to the first circuit board 14 on the side facing away from the base 12. Understandably, the first coil 161 is fixed to the base 12 via the first circuit board 14. The first magnetic element 162 is fixed to the side of the image stabilization bracket 17 facing the base 12. The first coil 161 faces the first magnetic element 162. The second coil 163 is fixed to and electrically connected to the first circuit board 14 on the side facing away from the base 12. The second coil 163 and the first coil 161 can be located on adjacent sides of the first circuit board 14. Understandably, the second coil 163 is fixed to the base 12 via the first circuit board 14. The second magnetic element 164 is fixed to the side of the image stabilization bracket 17 facing the base 12. The second coil 163 faces the second magnetic element 164. The first circuit board 14 can supply power to the first coil 161 and the second coil 163.

[0086] The motor 1 may include a first connector 21, a second connector 22, and a guide bracket 24. The number of first connectors 21 and second connectors 22 can both be multiple; for example, three are used in this embodiment. The first connector 21 may be a ball bearing structure; in other embodiments, it may be a sliding shaft or other structure. This application embodiment does not limit the specific structure of the first connector 21. The second connector 22 may be a ball bearing structure; in other embodiments, it may be a sliding shaft or other structure. This application embodiment does not limit the specific structure of the second connector 22.

[0087] The first connector 21 is movably connected between the base 12 and the guide bracket 24. Multiple first connectors 21 can be installed one-to-one in multiple grooves of the base 12, and the grooves can limit the movement of the first connectors 21. A portion of the outer surface of the first connector 21 can protrude relative to the surface of the base 12. Understandably, the guide bracket 24 also has a groove on the side facing the base 12 to accommodate the first connector 21. The first connector 21 can move within the groove along the second direction Y. Understandably, the guide bracket 24 is movably connected to the base 12 via the first connectors 21.

[0088] The second connector 22 can be movably connected between the guide bracket 24 and the image stabilization bracket 17. Multiple second connectors 22 can be installed one-to-one in multiple grooves of the guide bracket 24, and the grooves can limit the movement of the second connectors 22. A portion of the outer surface of the second connector 22 can protrude relative to the surface of the guide bracket 24. Understandably, the image stabilization bracket 17 also has a groove for accommodating the second connector 22 on the side facing the guide bracket 24. The second connector 22 can move within the groove along the first direction X. Understandably, the guide bracket 24 is movably connected to the image stabilization bracket 17 via the second connector 22.

[0089] Referring to Figures 7, 10, and 11, the base 12, guide bracket 24, and anti-shake bracket 17 are arranged sequentially along the third direction Z. A first connecting member 21 is provided between the base 12 and the guide bracket 24, and a second connecting member 22 is provided between the guide bracket 24 and the anti-shake bracket 17. The anti-shake bracket 17 can be movably connected to the base 12 through the guide bracket 24. A first coil 161 and a second coil 163 are fixed on the base 12, and a first magnetic element 162 and a second magnetic element 164 are fixed to the bottom of the anti-shake bracket 17. The guide bracket 24 can ensure the reliability of the connection between the anti-shake bracket 17 and the base 12, and can achieve stable support and accurate guidance, ensuring the stability of the relative positions of the first coil 161 and the first magnetic element 162, and the relative positions of the second coil 163 and the second magnetic element 164.

[0090] When motor 1 is performing image stabilization, the base 12, the first coil 161, and the second coil 163 are all fixed. The first coil 161 cooperates with the first magnetic element 162 and is used to drive the image stabilization bracket 17 and the first lens (the first lens is fixed inside the image stabilization bracket 17) to move relative to the base 12 in the first direction X. The second coil 163 cooperates with the second magnetic element 164 and is used to drive the image stabilization bracket 17 and the first lens to move relative to the base 12 in the second direction Y, so as to achieve image stabilization.

[0091] Motor 1 may include a first sensor 165 and a second sensor 166. The first sensor 165 and the second sensor 166 can be sensors used for detecting image stabilization, or sensors for other functions. Image stabilization drive mechanism 16 may include a first sensor 165 and a second sensor 166 for image stabilization. The first sensor 165 may be fixedly connected to and electrically connected to a first circuit board 14, and the first sensor 165 may be located inside a first coil 161. The second sensor 166 may be fixedly connected to and electrically connected to the first circuit board 14, and the second sensor 166 may be located inside a second coil 163. The first sensor 165 and the second sensor 166 may also be located in other positions. The first sensor 165 and the second sensor 166 can detect changes in the position of the image stabilization bracket 17, and the camera module can adjust the position of the image stabilization bracket 17 according to the detection results, thereby achieving better optical image stabilization.

[0092] In some embodiments, a magnetic yoke may be provided on the second side 122 of the base 12. There may be two magnetic yokes. The two magnetic yokes cooperate with the first magnetic element 162 and the second magnetic element 164 respectively to generate magnetic attraction force, pressing the image stabilization bracket 17 and the guide bracket 24 onto the base 12, which is beneficial for the movement of the image stabilization bracket 17 relative to the base 12.

[0093] Referring to Figures 7, 8, and 11, the motor 1 may include a focusing bracket 18 and a focusing drive mechanism 19. Both the focusing bracket 18 and the focusing drive mechanism 19 are located within the housing 11. The focusing bracket 18 may be located within the image stabilization bracket 17, and the focusing bracket 18 is movably connected to the image stabilization bracket 17. The focusing drive mechanism 19 is used to drive the focusing bracket 18 to move relative to the image stabilization bracket 17 in the third direction Z.

[0094] The motor 1 may also include a third connector 23. There may be multiple third connectors 23; for example, two are shown in this embodiment. The third connector 23 may be a sliding shaft or other structure; the structure of the third connector 23 is not limited in this embodiment. The two third connectors 23 may be fixed at two corners of the image stabilization bracket 17. The focusing bracket 18 is slidably connected to the image stabilization bracket 17 via the two third connectors 23.

[0095] The motor 1 may include a third circuit board 25, which can be fixed to the image stabilization bracket 17. Exemplarily, the third circuit board 25 can be a bent flexible circuit board, and can be approximately in the shape of a notched "U". The third circuit board 25 can also be other shapes, which are not limited in this embodiment. The third circuit board 25 surrounds and is fixed to the side of the image stabilization bracket 17 opposite to the focusing bracket 18, that is, the focusing bracket 18 is located inside the image stabilization bracket 17, and the third circuit board 25 is located outside the image stabilization bracket 17 and surrounds it. The third circuit board 25 can be fixed to the periphery of the image stabilization bracket 17 by means of adhesive or other methods. The third circuit board 25 can be electrically connected to the first circuit board 14.

[0096] Understandably, the first circuit board 14 can be a circuit board for image stabilization, the third circuit board 25 can be a circuit board for focusing, and the second circuit board 15 can be a circuit board for controlling the first circuit board 14 and the third circuit board 25. The first circuit board 14, the second circuit board 15, and the third circuit board 25 can also be circuit boards with other functions.

[0097] The focusing drive mechanism 19 may include a focusing coil 191 and a focusing magnetic component 192. The focusing coil 191 is fixed to the side of the third circuit board 25 facing the focusing bracket 18, and the focusing magnetic component 192 is fixed to the side of the focusing bracket 18 facing the focusing coil 191. The focusing coil 191 and the focusing magnetic component 192 are correspondingly arranged in the second direction Y to form a drive mechanism. The focusing coil 191 faces the focusing magnetic component 192. Understandably, the image stabilization bracket 17 may have a hole 171. When the third circuit board 25 and the focusing coil 191 are fixed to the image stabilization bracket 17, the focusing coil 191 may be located within the hole 171; in other words, the focusing coil 191 may be embedded in the image stabilization bracket 17. The third circuit board 25 supplies power to the focusing coil 191.

[0098] Understandably, the focusing coil 191 is fixed to the third circuit board 25, and the third circuit board 25 is fixed to the image stabilization bracket 17, that is, the focusing coil 191 is fixedly connected to the image stabilization bracket 17.

[0099] When the motor 1 is focusing, the focusing coil 191 and the focusing magnetic component 192 cooperate to drive the focusing bracket 18 and the second lens (the second lens is fixed inside the focusing bracket 18) to move relative to the base 12 and the image stabilization bracket 17 in the third direction Z to achieve focusing.

[0100] In some embodiments, the motor 1 may include a clamping member 26, at least a portion of which may be fixed to the side of the image stabilization bracket 17 away from the base 12. Exemplarily, a portion of the clamping member 26 may be fixed to the side of the image stabilization bracket 17 away from the base 12, while another portion of the clamping member 26 extends into the image stabilization bracket 17. In other embodiments, the entire clamping member 26 may be fixed to the side of the image stabilization bracket 17 away from the base 12. The clamping member 26, cooperating with the image stabilization bracket 17, can be used to limit the travel of the focusing bracket 18 in the third direction Z, preventing the focusing bracket 18 from disengaging from the image stabilization bracket 17 during focusing.

[0101] For example, the image stabilization drive mechanism 16 is used to drive the image stabilization bracket 17 to move the first lens, the focusing bracket 18, and the second lens relative to the base 12 along the first direction X and / or the second direction Y to achieve image stabilization. The focusing drive mechanism 19 is used to drive the focusing bracket 18 to move the second lens relative to the image stabilization bracket 17 along the third direction Z to make the second lens move closer to or further away from the first lens to achieve focusing.

[0102] It is understood that the structure of the main body 10 of the motor 1 in Figures 7 to 11 is only an exemplary representation. The embodiments of this application do not limit the specific structure of the main body 10 of the motor 1, and can be set as needed. The motor 1 can realize both image stabilization and focusing functions, or the motor 1 can realize image stabilization without focusing functions, or the motor 1 can have focusing functions without image stabilization functions, etc. The embodiments of this application do not limit the specific structure and function of the motor 1, and can be set as needed.

[0103] As shown in Figures 7, 12, and 13, Figure 12 is a partial structural schematic diagram of the main body 10 of the motor 1 shown in Figure 4, and Figure 13 is a partial structural schematic diagram of Figure 12. To clearly show the internal structure of the main body 10, the structure in Figure 12 is a schematic diagram of the main body 10 in Figure 4 after removing the housing 11. The structure in Figure 13, compared to the structure in Figure 12, removes the bonding member 28 and the third circuit board 25.

[0104] The motor 1 may include a second reinforcing member 27. The image stabilization bracket 17 is typically made of plastic, which has low structural strength, while the second reinforcing member 27 may be made of a material with high structural strength, such as metal. The second reinforcing member 27 may be embedded in the image stabilization bracket 17 to improve its structural strength. Exemplarily, a portion of the second reinforcing member 27 is embedded in the image stabilization bracket 17, while another portion of the second reinforcing member 27 is exposed outside the image stabilization bracket 17; this exposed portion is called the exposed portion 271. The number of exposed portions 271 may be one, two, or three, etc.

[0105] The motor 1 may include a bonding member 28, which is located on the side of the third circuit board 25 opposite to the image stabilization bracket 17. In other words, the image stabilization bracket 17, the third circuit board 25, and the bonding member 28 are arranged in sequence. The bonding member 28 and the third circuit board 25 can be fixedly connected by adhesive or other means. The bonding member 28 may be a magnetic yoke, which is correspondingly arranged with the focusing magnetic component 192. There is an attractive force between the magnetic yoke and the focusing magnetic component 192, so that the focusing bracket 18 and the image stabilization bracket 17 are tightly fitted, which is beneficial for the movement of the focusing bracket 18 relative to the image stabilization bracket 17. The bonding member 28 may also be a structural component with other functions.

[0106] The upper end of the bonding member 28 can be fixedly connected to the pressure member 26, and the lower end of the bonding member 28 can be fixedly connected to the exposed portion 271 of the second reinforcing member 27. For example, the bonding member 28 and the pressure member 26, and the bonding member 28 and the second reinforcing member 27 can be fixedly connected by welding.

[0107] Referring to Figures 12 and 13, the outer side of the focusing bracket 18 is a focusing magnetic component 192, the outer side of the focusing magnetic component 192 is a focusing coil 191, the focusing coil 191 can be embedded in the hole 171 of the image stabilization bracket 17, the outer side of the focusing coil 191 is a third circuit board 25, and the outer side of the third circuit board 25 is a bonding component 28.

[0108] Understandably, the third circuit board 25 can be fixed to the periphery of the image stabilization bracket 17 by adhesive. However, the adhesive area is limited, the adhesive strength is insufficient, and the adhesive is prone to aging, posing a risk of delamination and affecting the reliability of the connection between the third circuit board 25 and the image stabilization bracket 17. The bonding component 28 is also fixed to the third circuit board 25 by adhesive, but the adhesive strength is insufficient, and the adhesive is prone to aging, posing a risk of delamination and affecting the reliability of the connection between the bonding component 28 and the third circuit board 25.

[0109] This application embodiment makes full use of the bonding member 28. By setting the bonding member 28 to be fixedly connected with the pressure member 26 and the second reinforcing member 27, the third circuit board 25 is located in the space formed by the anti-shake bracket 17, the bonding member 28, the pressure member 26 and the second reinforcing member 27, which improves the connection reliability between the third circuit board 25 and the anti-shake bracket 17 and the bonding member 28, and effectively enhances the firmness.

[0110] As shown in Figure 14, Figure 14 is a partial structural diagram of the main body 10 of another type of motor 1 in the camera module 100 shown in Figure 2. The structure in Figure 14 is a structural diagram of the main body 10 of the motor 1 after the housing 11 is removed.

[0111] Motor 1 includes a heat-fitting component 31, which passes sequentially through the bonding component 28 and the third circuit board 25 and is fixedly connected to the anti-shake bracket 17. The heat-fitting component 31 can be integrally formed with the anti-shake bracket 17 or it can be a separate structure fixed together with the anti-shake bracket 17. Before its formation, the heat-fitting component 31 can be a columnar structure protruding and fixed to the surface of the anti-shake bracket 17. During the process of assembling the third circuit board 25 and the bonding component 28 sequentially onto the anti-shake bracket 17, the columnar structure passes sequentially through the through holes of the third circuit board 25 and the bonding component 28. The columnar structure is heat-melted and deformed, and the heated columnar structure is pressed to form the heat-fitting component 31. The heat-fitting component 31 can fix the third circuit board 25 and the bonding component 28 to the anti-shake bracket 17, which helps to improve the connection reliability between the third circuit board 25 and the bonding component 28 and the anti-shake bracket 17.

[0112] Understandably, the dimension of the end of the heat-riveting component 31 furthest from the image stabilization bracket 17 is larger than the dimension of the through hole on the third circuit board 25 and the bonding component 28 through which the heat-riveting component 31 passes. The dimensions in Figure 14 are only schematic representations. The number of heat-riveting components 31 can be one, two, or three, etc. In this embodiment, the number of heat-riveting components 31 is six.

[0113] As shown in Figures 15 and 16, Figure 15 is a partial structural schematic diagram of the main body 10 of another type of motor 1 in the camera module 100 shown in Figure 2, and Figure 16 is a partial structural schematic diagram of the structure shown in Figure 15. In order to clearly show the internal structure of the main body 10, the structure in Figure 15 is a structural schematic diagram of the main body 10 after the housing 11 is removed. The structure in Figure 16 is different from the structure in Figure 15 by removing the bonding member 28 and the image stabilization bracket 17.

[0114] The focusing coil 191 can be fixed to the image stabilization bracket 17. Exemplarily, the focusing coil 191 is fixed to the side of the image stabilization bracket 17 facing the focusing bracket 18. The motor 1 may include electrical connectors 29 that are electrically connected to the focusing coil 191 and the third circuit board 25. There may be two electrical connectors 29, each electrically connected to one end of the focusing coil 191. The electrical connectors 29 can be embedded in the image stabilization bracket 17 or fixed to other locations on the image stabilization bracket 17.

[0115] In this embodiment, the third circuit board 25 does not extend to the side 172 of the image stabilization bracket 17. The side 172 is the side where the focusing coil 191 is located; that is, there is no third circuit board 25 outside the side 172. The third circuit board 25 surrounds the other sides of the image stabilization bracket 17. The focusing coil 191 is fixed to the image stabilization bracket 17, not to the third circuit board 25. In Figures 15 and 16, the third circuit board 25 can be fixed to the image stabilization bracket 17 by the limiting member 261. In this embodiment, the focusing coil 191 and the third circuit board 25 are electrically connected by an electrical connector 29, so that the focusing coil 191 and the third circuit board 25 can be electrically connected even without the third circuit board 25 extending to the side 172. This avoids the problem of the third circuit board 25 extending to the side 172 needing to be bonded to the side 172 when it does extend. The solution of electrically connecting the focusing coil 191 and the third circuit board 25 by setting the electrical connector 29 is highly flexible.

[0116] As shown in Figures 7 and 17, Figure 17 is a partial structural schematic diagram of the main body 10 of the motor 1 shown in Figure 4. In order to clearly show the internal structure of the main body 10, the structure in Figure 17 is a structural schematic diagram of the main body 10 in Figure 4 after removing the housing 11 and the pressure member 26.

[0117] Motor 1 includes a focusing bracket 18, a focusing coil 191, a focusing magnetic element 192, and a focusing sensor 193. The focusing bracket 18 is located inside a housing, the focusing coil 191 is fixed inside the housing 11, and the focusing magnetic element 192 is fixed to the focusing bracket 18, with the focusing coil 191 facing the focusing magnetic element 192. The focusing coil 191 drives the focusing bracket 18 to move and achieve focusing. The focusing sensor 193 is located outside the focusing coil 191. When the focusing sensor 193 is located inside the area enclosed by the focusing coil 191, it detects the position of the focusing bracket 18 by detecting changes in the magnetic field of the focusing magnetic element 192. When the focusing coil 191 is energized, it generates an electromagnetic field, which interferes with the function of the focusing sensor 193, resulting in a large error in the position feedback of the focusing bracket 18. In this embodiment, by positioning the focus sensor 193 outside the focus coil 191, it is beneficial to avoid interference from the electromagnetic field generated by the focus coil 191 after it is energized, thereby improving the detection accuracy of the focus sensor 193.

[0118] In some embodiments, the motor 1 includes a magnetic grating 194, which is fixed to the focusing bracket 18 and faces the focusing sensor 193, which can be a tunnel magnetoresistive sensor. It is understood that by setting the magnetic grating 194 and configuring the focusing sensor 193 as a tunnel magnetoresistive sensor, the present application embodiments improve the detection accuracy of the focusing sensor 193.

[0119] As shown in Figure 18, which is a structural schematic diagram of the focusing bracket 18 of the motor 1 shown in Figure 4 and the second lens 3 of the camera module, the focusing bracket 180 may have a groove 181 on its inner wall 180. A colloid 182 is placed inside the groove 181. The second lens 3 has a protrusion 301, which is embedded in the colloid 182. Understandably, the second lens 3 can be mounted onto the focusing bracket 18, and then the colloid 182 can be injected into the groove 181.

[0120] In this embodiment, the inner wall 180 of the focusing bracket 18 is provided with a groove 181, and the protrusion 301 of the second lens 3 is embedded in the colloid 182 in the groove 181. This helps to ensure the reliability of the connection between the second lens 3 and the focusing bracket 18 and prevents the second lens 3 from coming out of the focusing bracket 18.

[0121] For example, the second lens 3 may include a first cylindrical body 302 and a second cylindrical body 303 connected as one unit. A protrusion 301 is located outside the second cylindrical body 303. The first cylindrical body 302 is located on the side of the second cylindrical body 303 away from the base. The dimension of the first cylindrical body 302 in the direction perpendicular to the third third direction Z is larger than the dimension of the second cylindrical body 303 in the same direction. The second cylindrical body 303 is located inside the focusing bracket 18, and the first cylindrical body 302 is located outside the focusing bracket 18. The first cylindrical body 302 overlaps with the surface 184 of the focusing bracket 18 facing away from the base.

[0122] In some embodiments, the focusing bracket 18 is provided with a notch 183, and the notch 183 and the groove 181 are arranged along the third direction Z. By providing the notch 183 in this embodiment, it is advantageous to inject the adhesive 182 into the groove 181 after the second lens 3 is installed on the focusing bracket 18. Understandably, adhesive 182 can usually be injected into the groove 181 using a needle. After the second lens 3 is installed on the focusing bracket 18, the first cylinder 302 overlaps the focusing bracket 18. Without the notch 183, it would be difficult to insert the needle between the second lens 3 and the focusing bracket 18, making adhesive dispensing impossible.

[0123] As shown in Figures 7, 19, and 20, Figure 19 is a partial structural schematic diagram of the main body 10 shown in Figure 7, and Figure 20 is a structural schematic diagram of the structure shown in Figure 19 from another angle. Figures 19 and 20 are views from opposite sides of the first circuit board 14.

[0124] The first circuit board 14 may include a first segment 141 and a second segment 142 fixedly connected. The first segment 141 and the second segment 142 may be adjacent to each other, and the extension directions of the first segment 141 and the second segment 142 may be different. For example, the first segment 141 may extend along a second direction Y, and the second segment 142 may extend along a first direction X. A first coil 161 and a second coil 163 are located on the same side of the first circuit board 14. The first coil 161 may be fixed to the first segment 141, and the second coil 163 may be fixed to the second segment 142. For example, the first coil 161 may be fixed to the side of the first segment 141 facing the through hole 113, and the second coil 163 may be fixed to the side of the second segment 142 facing the through hole 113.

[0125] Motor 1 may include a first reinforcing member 32 and a device 33. Device 33 is located on the side of the first circuit board 14 opposite to the through hole 113 and is electrically connected to the first circuit board 14. Device 33 may be located at the connection between the first segment 141 and the second segment 142. In other embodiments, device 33 may also be fixed to other positions on the first circuit board 14. Understandably, device 33 and the first coil 161 are located on opposite sides of the first circuit board 14, that is, device 33 and the second coil 163 are located on opposite sides of the first circuit board 14. Device 33 may be a driver chip, etc. The driver chip can be used to drive the image stabilization drive mechanism and the focus drive mechanism to achieve image stabilization or focus. The first reinforcing member 32 connects the first coil 161 and the second coil 163 into one unit. The first reinforcing member 32 may be made of plastic, etc., and the first reinforcing member 32 can be implemented by dispensing adhesive.

[0126] Understandably, device 33 is fixed and electrically connected to the first circuit board 14. Because the first circuit board 14 is relatively thin and lacks sufficient strength, it is prone to deformation during drops or collisions in the use of the electronic device 1000. This deformation can cause the solder joints connecting device 33 and the first circuit board 14 to crack, affecting the reliability of the electrical connection and thus the function of device 33. In this embodiment, a first reinforcing member 32 is provided to connect the first coil 161 and the second coil 163 into a single unit. The structure formed by connecting the first coil 161, the second coil 163, and the first reinforcing member 32 has high structural strength, increasing the structural strength of the first circuit board 14 and preventing poor electrical connection reliability between device 33 and the first circuit board 14 due to deformation of the first circuit board 14 during drops or collisions.

[0127] Referring to Figure 20, the motor includes a second reinforcing member 34. The second reinforcing member 34 is located on the side 331 of the device 33 and is fixed to the first circuit board 14. The second reinforcing member 34 is used to increase the structural strength of the first circuit board 14 and prevent the first circuit board 14 from deforming during a drop or collision, which would lead to poor electrical connection reliability between the device 33 and the first circuit board 14.

[0128] The number of second reinforcing members 34 can be one, two, or three, etc., and the number of second reinforcing members 34 is not limited in this embodiment. When there are two or more second reinforcing members 34, the multiple second reinforcing members 34 can surround and be distributed on multiple sides 331 of the device 33. The material of the second reinforcing members 34 can be metal or the like.

[0129] As shown in Figure 21, which is a schematic diagram of the structure shown in Figure 19 from another angle, the motor includes a third reinforcing member 35. The third reinforcing member 35 is located on the side of the device 33 facing away from the first circuit board 14 and is connected to at least two second reinforcing members 34. The third reinforcing member 35 and the at least two second reinforcing members 34 are connected as an integral structure. Exemplarily, the third reinforcing member 35 and the at least two second reinforcing members 34 can form a cover, with the device 33 located within the cover. In this embodiment, the provision of the third reinforcing member 35 significantly increases the structural strength of the first circuit board 14, avoiding the problem of poor electrical connection reliability between the device 33 and the first circuit board 14 caused by deformation of the first circuit board 14 during drops or collisions. The third reinforcing member 35 and the second reinforcing members 34 can be an integrally formed structure or separate structures assembled and fixed into an integral structure.

[0130] As shown in Figures 22 and 23, Figure 22 is an exploded view of another type of motor 1 in the camera module 100 shown in Figure 1, and Figure 23 is a partial structural diagram of the structure shown in Figure 22. The difference between the main body 10 of the motor shown in Figure 22 and the main body 10 of the motor shown in Figure 7 is that Figure 22 does not have the guide bracket 24 and the second connector 22 shown in Figure 7. The groove on the base 12 in Figure 22 for mounting the first connector 21 is larger, and the first connector 21 can move in all directions in the groove of the base 12, that is, the first connector 21 can move in the XY plane in the groove of the base 12. In Figure 7, the first connector 21 can only move in the second direction Y in the groove of the base 12.

[0131] The motor may include a third coil 167 and a third sensor 168. The third coil 167 may be a coil for driving image stabilization or a coil for other purposes. The third sensor 168 may be a sensor for detecting image stabilization or a sensor for other purposes. The image stabilization drive mechanism 16 may include a third coil 167 and a third sensor 168 for image stabilization. The first sensor 165 and the third sensor 168 are located on the same side of the first lens. Exemplarily, the first coil 161 and the third coil 167 are located on the same side of the first lens, the first sensor 165 is located within the first coil 161, and the third sensor 168 is located within the third coil 167.

[0132] Understandably, since the first connector 21 can move in the XY plane within the groove of the base 12, that is, the image stabilization bracket 17 and the first lens can move in the XY plane within the groove of the base 12, it is difficult to control the direction of movement of the first lens, making it difficult to achieve precise image stabilization in the desired direction. This embodiment improves the accuracy of the first lens's movement direction by setting the first sensor 165 and the third sensor 168 on the same side of the first lens. The first sensor 165 and the third sensor 168 are used to detect the movement of the first lens in the same direction. If the detection data of the first sensor 165 and the third sensor 168 are consistent, the first lens is moving in a preset direction to achieve precise image stabilization. If the detection data of the first sensor 165 and the third sensor 168 are different, the first lens has shifted its position during movement. This can be compensated by adjusting the current of the first coil 161 and / or the third coil 167, so that the first lens can move in a preset direction to achieve precise image stabilization.

[0133] It is understood that different embodiments of this application may be used in combination as needed, and the specific configuration may vary depending on the circumstances.

[0134] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
