Specifically, the camera module 1 is electrically connected to the processor 600 through the motherboard 500. When the processor 600 receives the instruction of the user, the processor 600 can send a signal to the camera module 1 through the motherboard 500 to control the camera module 1 to shoot images or record videos. In other embodiments, the camera module 1 may also directly receive an instruction of a user, and take an image or record a video according to the instruction of the user.

Referring to fig. 3 and 4, fig. 4 is a schematic view of a part of the camera module 1 with the structure shown in fig. 3.

The camera module 1 includes an optical lens 10, a photosensitive chip 20, a light converter 30 and a module circuit board 40. The module circuit board 40 is fixed on the light emitting side of the optical lens 10, that is, the module circuit board 40 is located on the image side of the optical lens 10. The module circuit board 40 may be electrically connected to the motherboard 500. In this way, signals can be transmitted between the main board 500 and the module circuit board 40.

The photosensitive chip 20 is fixed on a side of the module circuit board 40 facing the optical lens 10, and the photosensitive chip 20 is electrically connected to the module circuit board 40. Thus, after the light sensing chip 20 collects the light passing through the optical lens 10, the light sensing chip 20 generates a signal according to the light and transmits the signal to the main board 500 through the module circuit board 40.

In one embodiment, the photosensitive chip 20 may be mounted on the module circuit board 40 by a Chip On Board (COB) technique. In other embodiments, the photosensitive chip 20 may be packaged on the module circuit board 40 by Ball Grid Array (BGA) technology or Land Grid Array (LGA) technology.

In other embodiments, electronic components or other chips (e.g., driving chips) are also mounted on the module circuit board 40. Electronic components or other chips are disposed around the photosensitive chip 20. The electronic component or other chips are used to assist the photosensitive chip 20 in collecting light, and the auxiliary photosensitive chip 20 performs signal processing on the collected light.

In other embodiments, the module circuit board 40 may also be partially provided with a sink, and in this case, the photosensitive chip 20 may be mounted in the sink. In this way, the photosensitive chip 20 and the module circuit board 40 have an overlapping area in the X-axis direction, and at this time, the image pickup module 1 can be set thin in the X-axis direction.

The light-converting member 30 is fixed on the light-incident side of the optical lens 10, and the light-converting member 30 is used for reflecting light so that the light is transmitted into the optical lens 10. In this embodiment, the light conversion member 30 may be used to reflect the light propagating along the Z-axis direction to the light propagating along the X-axis direction. Light from the environment enters the light conversion member 30 through the camera hole 1003, and is reflected to the optical lens 10 by the light conversion member 30. In other embodiments, the light diverting member 30 may be used to reflect light propagating along the Z-axis to light propagating along other directions.

The light-converting member 30 is exemplified as a prism, but the light-converting member 30 may be a reflector. The light converter 30 includes a light incident surface 31, a light reflecting surface 32 and a light emitting surface 33. The reflection surface 32 is connected between the light incident surface 31 and the light emitting surface 33. The light incident surface 31 is disposed opposite to the imaging hole 1003. The light emitting surface 33 is disposed opposite to the optical lens 10. At this time, after entering through the camera hole 1003, the light enters into the light conversion member 30 through the light incident surface 31, and is reflected at the reflection surface 32 of the light conversion member 30. At this time, the light traveling in the Z-axis direction is reflected to travel in the X-axis direction. Finally, the light passes through the light exit surface 33 of the light conversion member 30 and then exits the light conversion member 30, and enters the optical lens 10.

It is understood that the light traveling in the Z-axis direction is reflected by the light-turning member 30 to travel in the X-axis direction. In this way, the devices of the camera module 1 that receive the light propagated in the X-axis direction can be arranged in the X-axis direction. Because the size of electronic equipment 1000 in the X axle direction is great, the device in the module of making a video recording 1 is more nimble in arranging of X axle direction, and is simpler. In this embodiment, the optical axis direction of the image pickup module 1 is the X-axis direction. In other embodiments, the optical axis direction of the camera module 1 may be the Y-axis direction.

In this embodiment, the light-converting member 30 may be provided with a motor (not shown), and the position of the light-converting member 30 in the Z-axis or X-axis direction can be adjusted by the motor, or the inclination of the light-converting member 30 with respect to the plane of the XY-axis can be adjusted. The light conversion member 30 can rotate on the XZ plane with the Y axis as a rotation axis. The light conversion member 30 can also be rotated on the XY plane with the Z axis as a rotation axis. It can be understood that the camera module 1 shakes easily in the process of collecting light, and at the moment, the transmission path of light deflects easily, so that the image shot by the camera module 1 is poor. In this embodiment, when the transmission path of the light deflects, the motor can drive the light rotating member 30 to rotate, so as to adjust the transmission path of the light by using the light rotating member 30, thereby achieving focusing, reducing or avoiding the deflection of the transmission path of the light, and further ensuring that the camera module 1 has a better shooting effect. Therefore, the light conversion member 30 can have an optical anti-shake effect.

In some embodiments, the camera module 1 further includes an optical filter located on a side of the photosensitive chip 20 facing the optical lens 10. The optical filter may be used to filter stray light of the light passing through the optical lens 10, and transmit the filtered light to the photosensitive chip 20, so as to ensure that the image captured by the electronic device 1000 has better definition. The filter may be, but is not limited to, a blue glass filter. For example, the filter may be a reflective infrared filter, or a double-pass filter (the double-pass filter may transmit visible light and infrared light of light simultaneously, or transmit visible light and other specific wavelength light (e.g., ultraviolet light) simultaneously, or transmit infrared light and other specific wavelength light (e.g., ultraviolet light) simultaneously).

In a scenario of another embodiment, please refer to fig. 5, and fig. 5 is a schematic structural diagram of another embodiment of the camera module 1 shown in fig. 4.

The embodiment shown in fig. 5 is substantially the same as the embodiment shown in fig. 4, except that the image pickup module 1 in the embodiment shown in fig. 5 further includes a first lens 50 and a second lens 60, the first lens 50 is disposed between the light-transferring member 30 and the optical lens 10, and the second lens 60 is disposed between the optical lens 10 and the photosensitive chip 20. In the present embodiment, the number of the first lenses 50 is three, and the number of the second lenses 60 is three. The ambient light emitted from the light converter 30 enters the optical lens 10 through the first lens 50, and then is emitted from the optical lens 10, and then is sensed by the photo sensor chip 20 through the second lens 60. After the light is processed by the first lens 50, the optical lens 10 and the second lens 60, the light is in accordance with the imaging quality (including correcting distortion, aberration and the like), and is finally projected on the photosensitive chip 20. And by driving the optical lens 10, the optical lens 10 can move in the X-axis direction relative to the first lens 50 and the second lens 60, so as to change the optical characteristics (including aperture, focal length, etc.) formed by the first lens 50, the optical lens 10, and the second lens 60, thereby achieving the effect of optical zooming and satisfying various optical characteristics required by actual use. Of course, in other embodiments, the number of the first lenses 50 may also be one, two or more than three, and the number of the second lenses 60 may also be one, two or more than three.

In another scenario of other embodiments, please refer to fig. 6, and fig. 6 is a schematic structural diagram of another embodiment of the camera module 1 shown in fig. 5.

The embodiment shown in fig. 6 is substantially the same as the embodiment shown in fig. 5, except that the image module 1 in the embodiment shown in fig. 6 further includes a reflector 70, the reflector 70 is disposed on a side of the second lens 60 opposite to the optical lens 10, and the photosensitive chip 20 is disposed below the reflector 70, it can be understood that the reflector 70 and the photosensitive chip 20 are disposed at an interval in the Z-axis direction. In this embodiment, the reflector 70 is a triangular prism, an incident surface of the reflector 70 faces the second lens 60, and an exit surface of the reflector 70 faces the photosensitive chip 20. The light from the second lens 60 is reflected to the photo chip 20 through the reflection member 70, that is, the reflection member 70 reflects the light traveling in the X-axis direction to the light traveling in the Z-axis direction. Of course, in other embodiments, the reflector 70 may also be a mirror.

It is understood that, by providing the reflecting member 70 in the present embodiment, the light sensing plane of the light sensing chip 20 can be perpendicular to the Z axis; for an apparatus having a strict limitation on the dimension in the Z-axis direction (i.e., the thickness of the entire apparatus), and a relatively sufficient dimension in the X-axis and Y-axis directions, the arrangement of the photosensitive chips 20 having a larger dimension can be realized, thereby improving the image quality. It can be understood that, for a certain optical lens and a certain focusing distance, the distance from the rear end face of the optical lens to the photosensitive chip is certain, so that if the optical lens and the photosensitive chip are placed along the X axis, the dimensions from the rear end face of the optical lens to the photosensitive chip are all in the X axis direction. By providing the reflecting member 70, the rear focal optical path of the optical lens 10 is arranged at a right angle, and compared with the design of the rear Jiao Zhixian optical path without the reflecting member 70, the size of the whole camera module 1 in the X-axis direction can be shortened by introducing the reflecting member 70.

In this embodiment, the reflection member 70 may be disposed on a motor (not shown), and the position of the reflection member 70 in the Z-axis or X-axis direction is adjusted by the motor, or the inclination of the reflection member 70 with respect to the plane of the XY-axis is adjusted. The reflector 70 can rotate in the XZ plane about the Y axis as a rotation axis. The reflector 70 may be rotatable in the XY plane about the Z axis as a rotation axis. It can be understood that the camera module 1 shakes easily in the process of collecting light, and at the moment, the transmission path of light deflects easily, so that the image shot by the camera module 1 is poor. In this embodiment, when the transmission path of the light deflects, the motor can drive the reflector 70 to rotate, so as to adjust the transmission path of the light by using the reflector 70, thereby achieving focusing, reducing or avoiding the deflection of the transmission path of the light, and further ensuring that the camera module 1 has a better shooting effect. Therefore, the reflection member 70 may have an optical anti-shake effect.

In the present application, the optical lens 10 has a variety of arrangements. Various setting modes of the optical lens 10 can be applied to the camera module 1 shown in fig. 4, 5 and 6, and can also be applied to camera modules which need to push the lens or the photosensitive chip 20 and the circuit board thereof to perform auto-focusing or zooming of large stroke displacement, including vertical camera modules, periscopic camera modules, and the like. Several arrangements of the optical lens 10 will be described in detail below with reference to the accompanying drawings.

The first embodiment: referring to fig. 7 and 8, fig. 7 is a schematic structural diagram of an embodiment of the optical lens 10 shown in fig. 4. Fig. 8 is an exploded structural schematic diagram of the optical lens 10 shown in fig. 7.

The shell 11 surrounds to form a movable space A, the sliding rod 14 is installed on the shell 11, the lens 12 is installed on the carrier 13, the carrier 13 is located in the movable space A and matched with the sliding rod 14, and the carrier 13 can slide relative to the sliding rod 14. The circuit board 15 is disposed inside the housing 11, and the circuit board 15 is used for driving the lens 12 to move in the optical axis direction. Of course, in other embodiments, the slider 14 may also be mounted to a surface of the housing 11.

In this embodiment, the extending direction of the sliding rod 14 is the same as the optical axis direction of the lens 12, and the carrier 13 drives the lens 12 to slide along the extending direction of the sliding rod 14, so that the lens 12 does not deflect during the moving and focusing processes. And the components such as the lens 12, the carrier 13, the sliding rod 14 and the like are all accommodated in the shell 11, which is beneficial for assembling the components to form modularization, thereby simplifying the assembling process of the camera module 1 and reducing the cost of the camera module 1.

The housing 11 includes a first light passing hole 101 and a second light passing hole 102. The first light hole 101 and the second light hole 102 are disposed opposite to each other on both sides of the housing 11, and both penetrate the inside and the outside of the housing 11. The light emitted from the light emitting surface 33 of the light converter 30 enters the optical lens 10 through the first light passing hole 101, and exits the optical lens 10 through the second light passing hole 102 after passing through the optical lens 10.

As shown in fig. 8, the housing 11 includes a frame 11A and a cover 11B, and the cover 11B is sleeved on the frame 11A to form a movable space a with the frame 11A for accommodating elements such as the carrier 13 and the lens 12. The first light-passing hole 101 is formed in the cover 11B, and the second light-passing hole 102 is formed in the holder 11A. The circuit board 15 is fixed to the outer surface of the frame body 11A and is located between the frame body 11A and the cover body 11B. The housing 11 in this embodiment is composed of two parts (a frame body 11A and a cover body 11B) to facilitate assembly of the optical lens 10.

Referring to fig. 8 and 9, fig. 9 is a schematic cross-sectional view of the optical lens 10 shown in fig. 7 along the direction B-B.

The frame body 11A comprises a mounting groove 111, and the mounting groove 111 is communicated with the movable space A. The sliding rod 14 is cylindrical, a part of the sliding rod 14 is located in the moving space A, a part of the sliding rod 14 is located in the installation groove 111, and two ends of the sliding rod 14 are fixed on the frame body 11A. A gap is formed between the sliding rod 14 and the groove wall of the mounting groove 111, and the colloid 16 is positioned in the gap and bonds the sliding rod 14 and the groove wall of the mounting groove 11. The carrier 13 has a sliding slot 131, the carrier 13 is disposed on a side of the sliding rod 14 opposite to the mounting slot 111, the sliding rod 14 is partially disposed in the sliding slot 131 and contacts with a slot wall of the sliding slot 131, and the sliding slot 131 slides relative to the sliding rod 14.

It can be understood that the optical lens 10 in the present embodiment fixes the sliding rod 14 to the mounting groove 111 by partially disposing the sliding rod 14 in the mounting groove 111 and forming a gap between the sliding rod 14 and a wall of the mounting groove 111, and filling the gap with the glue 16 to fix the sliding rod 14 to the mounting groove 111, so that the sliding rod 14 is stably fixed in the mounting groove 111. The glue 16 also serves to support the slide 14 and prevent the slide 14 from deforming under the influence of external forces. And the portion of the slide bar 14 contacting the mounting groove 111 does not contact other parts, so that the contact force of the portion contacting other parts to the slide bar 14 is prevented from causing deformation of the slide bar 14. Slide bar 14's both ends still are fixed in support body 11A to slide bar 14 no matter is still located the equal firm fixing of part of mounting groove 111 on support body 11A at both ends, is difficult for droing from support body 11A, and slide bar 14 is longe-lived, effectively improves slide bar 14's direction stability, avoids camera lens 12 to rock at the slip in-process, and carrier 13 can be steady relative slide bar 14 slides, guarantees the imaging of module of making a video recording 1.

Meanwhile, the carrier 13 is matched with the sliding rod 14 through the sliding groove 131, and compared with the matching of the through hole and the sliding rod 14, the problem that the through hole and the sliding rod 14 are blocked due to the deflection of the carrier 13 can be effectively avoided, so that the carrier 13 can slide more smoothly relative to the sliding rod 14. And the cooperation of the sliding chute 131 and the sliding rod 14, compared with the guide structure of the elastic sheet and the balls, the problem that the elastic force of the elastic sheet can weaken the driving force to cause the pain point of the carrier 13 of the elastic sheet optical lens which can not move in a large stroke is solved, the problem that the pain point of the carrier 13 which is unstable in driving due to the fact that the balls are staggered is also solved, and the long-stroke stable driving of the carrier 13 can be realized.

Referring to fig. 10A and fig. 11, fig. 10A is an exploded view of a portion of the optical lens 10 shown in fig. 8. Fig. 11 is a schematic view of another angle of the frame body 11A of the structure shown in fig. 10A.

The rack 11A includes a base plate 112, a first side plate 113, a second side plate 114, and a third side plate 115. The first side plate 113, the base plate 112 and the second side plate 114 are connected in sequence, the first side plate 113 and the second side plate 114 are oppositely arranged, and the third side plate 115 is connected between the first side plate 113 and the second side plate 114 and connected with the base plate 112. It is also understood that the first side plate 113, the second side plate 114 and the third side plate 115 are connected in sequence and are all disposed on the substrate 112. The substrate 112, the first side plate 113, the second side plate 114, and the third side plate 115 enclose a space for accommodating devices such as the lens 12 and the carrier 13, which is beneficial to modularization of the optical lens 10.

In this embodiment, the base plate 112, the first side plate 113, the second side plate 114 and the third side plate 115 are integrally formed to be an integral structure, so as to ensure the overall strength of the frame body 11A. Of course, in other embodiments, the base plate 112, the first side plate 113, the second side plate 114, and the third side plate 115 may be assembled to form the frame body 11A by a bonding process, such as adhesion.

Illustratively, the base plate 112 and the third side plate 115 both protrude from the surface of the first side plate 113 away from the second side plate 114, and the portion of the base plate 112 and the third side plate 115 protruding from the surface of the first side plate 113 away from the second side plate 114 forms a first accommodating space 110a with the first side plate 113.

The first, second, and

third housing spaces

110a, 110b, and 110c communicate for housing the circuit board 15.

Of course, in an implementation scenario of other embodiments, the first accommodating space 110a, the second accommodating space 110b and the third accommodating space 110c may be arranged as needed. Or the first, second, and

third receiving spaces

110a, 110b, and 110c are not limited to being formed by the above-described structure. In another implementation scenario of other embodiments, the base plate 112 facing away from the first side plate 113 may further form a fourth accommodating space communicating with the first accommodating space 110a and the second accommodating space 110b.

Referring to fig. 8, 10B and 11, fig. 10B is a schematic structural diagram of the circuit board 15 and other structures of the structure shown in fig. 10A.

The circuit board 15 includes a first portion 151, a second portion 152, and a third portion 153 electrically connected, the third portion 153 being connected between the first portion 151 and the second portion 152. The first portion 151 is disposed outside the first side plate 113 and is received in the first receiving space 110a, the second portion 152 is disposed outside the second side plate 114 and is received in the second receiving space 110b, and the third portion is received in the third receiving space 110c.

In this embodiment, the first portion 151, the second portion 152, and the third portion 153 are integrated. The first, second and

third portions

151, 152 and 153 may be fixed to the frame body 11A by gluing. The circuit board 15 is a flexible circuit board, so as to be bent and disposed in the first receiving space 110a, the second receiving space 110b and the third receiving space 110c. The circuit board 15 may integrate a driving chip, a temperature sensor, a displacement sensor, a coil, and components for adjusting circuit characteristics, such as resistance, capacitance, inductance, and the like.

Of course, in an implementation scenario of other embodiments, the circuit board 15 may also be a rigid circuit board, and the third portion 153 and the first portion 151 and the second portion 152 may be electrically connected through a wire, a conductive metal, or a flexible circuit board. In another implementation scenario of other embodiments, the first portion 151, the second portion 152, and the third portion 153 may also be fixed to the frame body 11A by other connection methods besides gluing.

As shown in fig. 8 and 10B, the optical lens 10 further includes a reinforcing plate 17. In this embodiment, the number of the reinforcing plates 17 may be three, one reinforcing plate 17 is disposed on the surface of the first portion 151 away from the first side plate 113, one reinforcing plate 17 is disposed on the surface of the second portion 152 away from the second side plate 114, and one reinforcing plate 17 is disposed on the surface of the third portion 153 away from the base plate 112. The reinforcing plate 17 serves to increase the strength of the circuit board 15. The reinforcing plate 17 can be fixed on the surface of the circuit board 15 away from the frame body 11A by gluing, and the surface of the reinforcing plate 17 away from the circuit board 15 can be fixed with the cover body 11B by gluing through the glue 16.

As shown in fig. 9 and 11, a mounting groove 111 is formed in the substrate 112. The substrate 112 includes a middle portion 1121 and edge portions 1122 connected to both sides of the middle portion 1121. One of the edge portions 1122 is disposed adjacent the first side panel 113 and the other edge portion 1122 is disposed adjacent the second side panel 114. The number of the mounting grooves 111 is two, and the two mounting grooves 111 are formed at the corresponding edge portions 1122, respectively. Correspondingly, the number of the sliding rods 14 is also two, and the two sliding rods 14 are matched with the two mounting grooves 111 in a one-to-one correspondence manner.

In this embodiment, the thickness of the edge portion 1122 is greater than the thickness of the middle portion 1121 to facilitate forming the mounting groove 111. The thickness of the edge portion 1122 is greater than that of the middle portion 1121, and it can be understood that the middle portion 1121 of the substrate 112 is a groove formed in the substrate 112, and the groove is used for avoiding the carrier 13, so as to reduce the thickness of the optical lens 10 in the Z-axis direction, thereby facilitating the thinning of the electronic device 1000. Of course, in other embodiments, the thickness of the middle portion 1121 of the substrate 112 may also be the same as the thickness of the edge portion 1122.

In this embodiment, as shown in fig. 9, the cross section of the mounting groove 111 is an inverted trapezoid, and the glue 16 is connected between the wall of the mounting groove 111 and the surface of the sliding rod 14 located in the mounting groove 111. It can be understood that, because the cross section of the sliding rod 14 is circular, the width of the sliding rod 14 in the direction away from the mounting groove 111 becomes smaller and smaller, the cross section of the mounting groove 111 is designed to be an inverted trapezoid, which is beneficial to saving glue and reducing cost, and meanwhile, the mounting groove 111 of the inverted trapezoid also has a limiting effect on the sliding rod 14, so as to realize the positioning of the sliding rod 14.

As shown in fig. 10A and 11, the housing 11 further includes a dispensing slot 116, and the dispensing slot 116 is formed on the substrate 112 of the frame 11A. The dispensing slot 116 is located at the edge of the mounting slot 111 and is communicated with the mounting slot 111, and the glue 16 extends from the dispensing slot 116 to the gap. It can be understood that the slide bar 14 is assembled to the frame body 11A by fixing the slide bar 14 to the frame body 11A and then filling the glue 16 into the gap between the slide bar 14 and the mounting groove 111. Through setting up some gluey grooves 116, can with bonding glue point to some gluey inslot 116, flow to mounting groove 111 through some gluey groove 116, fill in the clearance between mounting groove 111 and slide bar 14 for the better filling of bonding glue is in the gap between slide bar 14 and mounting groove 111, forms colloid 16 after the bonding glue solidification, makes more firm being fixed in support body 11A of slide bar 14.

In this embodiment, one mounting groove 111 corresponds to at least one dispensing groove 116. In the embodiment shown in fig. 11, one mounting groove 111 corresponds to two dispensing grooves 116, and the two dispensing grooves 116 are respectively located at one side of two ends of the mounting groove 111 and are communicated with the mounting groove 111. During dispensing, two dispensing slots 116 can be dispensed simultaneously, so that the glue can be rapidly filled in the gap between the mounting slot 111 and the sliding rod 14. Of course, the two dispensing slots can also be respectively located at two sides of the mounting slot 111. Or a plurality of dispensing slots communicated with the mounting slot 111 can be arranged on two sides of the mounting slot.

As shown in fig. 9, the reinforcing steel sheet 1123 is disposed inside the middle portion 1121 of the base plate 112 to enhance the strength of the base plate 112, and ensure that the base plate 112 is thin enough and is not easily damaged by an external force. Illustratively, the reinforcing steel sheet 1123 may be formed inside the base plate 112 by an insert molding process.

Referring to fig. 10A and 11 again, the first side plate 113 is a plate body, the first side plate 113 includes an outer side surface 1131 and a first avoiding space 1132, and the first portion 151 of the circuit board 15 is fixed on the outer side surface 1131. Specifically, the outer side surface 1131 is provided with a positioning pillar 1133, and the positioning pillar 1133 is used for positioning and limiting the first portion 151 of the circuit board 15, so that the first portion 151 of the circuit board 15 is conveniently mounted on the outer side surface 1131. The number of locating posts 1133 can be set as desired. The first avoiding space 1132 penetrates through the outer side surface 1131 of the first side plate 113 and a surface opposite to the outer side surface 1131, and the first avoiding space 1132 is used for avoiding relevant components arranged on the first portion 151, so as to realize miniaturization of the optical lens 10 in the Y axis direction.

The second side plate 114 is a plate body, the second side plate 114 includes an outer side surface 1141 and a second avoiding space 1142, and the second portion 152 of the circuit board 15 is fixed to the outer side surface 1141. Specifically, the outer side surface 1141 is provided with a positioning column (not shown), and the positioning column is used for positioning and limiting the second portion 152 of the circuit board 15, so that the second portion 152 of the circuit board 15 is conveniently mounted on the outer side surface 1141. The number of the positioning columns can be set as required. The second avoidance space 1142 penetrates the outer side surface 1141 of the second side plate 114 and the surface facing the outer side surface 1141, and the second avoidance space 1142 is used to avoid the relevant components provided in the second portion 152, thereby realizing miniaturization of the optical lens 10 in the Y-axis direction.

The third side plate 115 is a plate body, and the second light passing hole 102 penetrates through two opposite surfaces of the third side plate 115. The second light passing hole 102 is for communicating the outside and the inside of the housing 11A to allow light to be emitted from the optical lens 10. An avoiding opening 1151 is formed in a side, away from the substrate 112, of the third side plate 115, the third portion 153 of the circuit board 15 includes a connecting end, and the connecting end of the third portion 153 extends out of the optical lens 10 through the avoiding opening 1151 to be electrically connected with a module circuit board 1540 of the camera module 1. The number of bypass ports 1151 may correspond to the number of connection ends.

As shown in fig. 10A and 11, the frame body 11A further includes a first fixing portion 117 and a second fixing portion 118. In this embodiment, the number of the first fixing portions 117 and the second fixing portions 118 is two, and one first fixing portion 117 and one second fixing portion 118 are respectively located at two ends of one mounting groove 111. Illustratively, the second fixing portion 118 is a through hole formed in the third side plate 115, and the second fixing portion 118 is disposed opposite to the notch of the corresponding mounting groove 111. The first fixing portion 117 connects the base plate 112 and the first side plate 113, and the first fixing portion 117 includes a through hole disposed opposite to a notch of the corresponding mounting groove 111.

The two ends of the sliding rod 14 are fixed to the first fixing portion 117 and the second fixing portion 118, respectively, that is, the two ends of the sliding rod 14 are fixed in the two through holes, respectively. The two ends of the sliding rod 14 can be fixed in the two through holes through interference fit. Of course, in other embodiments, the two ends of the sliding rod 14 may also be fixed to the cover 11B by welding or other connection methods. Alternatively, the two ends of the sliding rod 14 can be fixed in the two through holes by other methods.

The second fixing portion 118 in this embodiment is a through hole formed in the third side plate 115, and is directly formed by using the original structure of the frame body 11A, and the fixing of one end of the sliding rod 14 can be achieved without introducing a new structure, so that the structure of the optical lens 10 is simpler, and the miniaturization of the optical lens 10 is facilitated.

Referring to fig. 12, fig. 12 is a partial structural diagram of the structure shown in fig. 8.

The first fixing portion 117 includes a first fixing surface 1171, a second fixing surface 1172, and a third fixing surface 1173 that are sequentially connected, and the first fixing surface 1171, the second fixing surface 1172, and the third fixing surface 1173 are disposed around one end of the slide bar 14 and cooperate to fix one end of the slide bar 14. Illustratively, the first and

second fixing surfaces

1171 and 1172 are substantially V-shaped, and the third fixing surface 1173 faces the junction of the first and

second fixing surfaces

1171 and 1172. The slide rod 14 is fixed by contact and cooperation with the first fixing surface 1171, the second fixing surface 1172 and the third fixing surface 1173, so that the slide rod 14 can be more stably fixed at the first fixing portion 117.

As shown in fig. 9 and 12, the first fixing portion 117 in this embodiment further includes an avoidance gap 1174, the avoidance gap 1174 is located between the first fixing surface 1171 and the third fixing surface 1173, and the avoidance gap 1174 is used for avoiding the carrier 13. It can be understood that, in the process of focusing the camera module 1, the carrier 13 drives the lens 12 to move in the optical axis direction, and the first fixing portion 117 is provided with the avoiding notch 1174, so that the path along which the carrier 13 can drive the lens 12 (fig. 9) to move in the X axis direction is longer, the focusing effect is improved, and the imaging effect of the camera module 1 is effectively improved. Meanwhile, the avoiding notch 1174 can also avoid the carrier 13 in the Z-axis direction, so that the carrier 13 can be arranged close to the substrate 112 in the Z-axis direction without touching the first fixing portion 117, which is beneficial to the miniaturization of the optical lens 10 in the Z-axis direction.

As shown in fig. 10A and 12, the second fixing portion 118 includes a first wall 1181, a second wall 1182, and a third wall 1183 connected in sequence, and the first wall 1181, the second wall 1182, and the third wall 1183 form a through hole with complete hole wall. A first wall 1181, a second wall 1182, and a third wall 1183 are disposed around the other end of the slide rod and cooperate to secure the other end of the slide rod 14. The sliding rod 14 is fixed by contacting and matching with the first wall 1181, the second wall 1182 and the third wall 1183, so that the sliding rod 14 can be more stably fixed on the second fixing portion 118.

It is understood that the through hole of the first fixing portion 117 is a through hole having an incomplete hole wall. The second fixing portion 118 is a through hole with a complete hole wall, so that when the sliding rod 14 is installed to the two fixing portions, one end of the second fixing portion 118 can be inserted, and the other end of the second fixing portion can be buckled into the first fixing portion 117 through the avoiding notch 1174, which is more convenient for installation.

Referring to fig. 9 and 12 again, the optical lens 10 further includes a magnetic conductive sheet 18, and the magnetic conductive sheet 18 is disposed on the substrate 112 at an interval of the mounting groove 111. In this embodiment, the number of the magnetic conductive pieces 18 is two, and one magnetic conductive piece 18 is disposed on one edge portion 1122 of the substrate 112 and located between the mounting groove 111 and the first side plate 113. A magnetic conductive plate 18 is disposed on the other edge portion 1122 of the base plate 112 and between the mounting groove 111 and the second side plate 114. The magnetic conducting plate 18 is used to cooperate with the relevant parts arranged on the carrier 13 so as to make the carrier 13 abut against the sliding rod 14 and prevent the carrier 13 from separating from the sliding rod 14 when sliding relative to the sliding rod 14. The magnetic conductive plate 18 can be fixed to the substrate 112 by adhesion, and of course, the magnetic conductive plate 18 can also be fixed to the substrate 112 by other connection methods besides adhesion. The magnetic conductive sheet 18 can also be integrally formed on the substrate 112 by an insert molding process, so that the assembly process of the optical lens 10 is reduced, and the production efficiency of the product is improved.

In other embodiments, the optical lens 10 may not be provided with a magnetic conductive sheet, and instead, the sliding rod 14 may be made of a magnetic conductive material, or the surface of the sliding rod 14 may be coated with a magnetic conductive material. The slide 14 cooperates with associated features on the carrier 13 to hold the carrier 13 against the slide 14 to prevent the carrier 13 from disengaging the slide 14 as it slides relative to the slide 14.

Referring to fig. 13 and 14, fig. 13 is a schematic structural view of the cover 11B in the structure shown in fig. 8. Fig. 14 is a schematic cross-sectional structure view of the optical lens 10 shown in fig. 7 in the C-C direction.

The enclosure 11B includes a top wall 119, a first sidewall 120, a second sidewall 121, and a third sidewall 122. First 120 and second 121 sidewalls are connected to the top wall 119 in spaced relation to one another, and a third sidewall 122 is connected between the first 120 and second 121 sidewalls and to the top wall 119. It is also understood that the first side wall 120, the third side wall 122 and the second side wall 121 are sequentially connected to the top wall 119. The first light passing hole 101 is formed in the third sidewall 122. When the cover 11B is fixed to the frame 11A, the first side wall 120 is located outside the first side plate 113 of the frame 11A to close the first accommodating space 110a (fig. 11). The second side wall 121 is located at an outer side of the second side plate 114 of the frame 11A to close the second receiving space 110b. The top wall 119 is disposed opposite to the substrate 112, and the top wall 119 closes the third receiving space 110c. The third sidewall 122 is disposed opposite to the third sidewall 115, and light enters the optical lens 10 through the first light passing hole 101 and exits the optical lens 10 through the second light passing hole 102.

In this embodiment, as shown in fig. 10B and 13, the first side wall 120, the second side wall 121, and the top wall 119 are all provided with a dispensing hole 123, so that dispensing is performed through the dispensing hole 123, so that the glue enters into the cover 11B to fix the cover 11B and the frame 11A. Specifically, the first sidewall 120 is adhered and fixed to the reinforcing plate 17 located in the first accommodating space 110a through the first adhesive. The second sidewall 121 is bonded and fixed to the reinforcing plate 17 of the second receiving space 110b by the second adhesive. The top wall 119 is fixed to the reinforcing plate 17 of the third accommodating space 110c by the third adhesive. Of course, in other embodiments, the first side wall 120, the second side wall 121, and the top wall 119 may be secured to the corresponding structures by other means of attachment.

Referring to fig. 14 and 15, fig. 15 is an exploded view of the structure shown in fig. 13.

The surface of the cover 11B facing the base plate 112 is provided with a protrusion 124. Specifically, the top wall 119 includes a sunken groove 125, and a bottom wall of the sunken groove 125 is provided with a through hole 1251 and a protrusion 1252 protruding from a surface of the top wall 119 facing the substrate 112. The protrusion 124 is formed in the groove 125 by an insert molding process and wraps the protrusion 1252. The protrusion 124 is used for matching with the carrier 13 to limit the carrier 13, so as to ensure that the carrier 13 does not deflect in the process of driving the lens 12 to focus. Of course, in other embodiments, the protrusion 124 may be fixed to the top wall by other means of attachment, such as adhesive, snap-fit, etc.

In this embodiment, the protrusion 1252 has the function of enhancing the strength of the protrusion 124, the through hole 1251 facilitates forming the protrusion 124, and the portion of the protrusion 124 fixed to the top wall 119 is formed in the sinking groove 125, which is beneficial to reducing the thickness of the optical lens 10 in the Z-axis direction and the miniaturization of the optical lens 10. Meanwhile, the protrusion 124 is formed by an insert molding process, so that the process of assembling the protrusion 124 to the top wall 119 is reduced, and the protrusion 124 can be more firmly fixed to the top wall 119.

It can be understood that the sliding rod 14 limits the position of the carrier 13 below the carrier 13, and the protrusion 124 limits the position of the carrier 13 above the carrier 13, so as to limit the position of the carrier 13 completely, and effectively provide the focusing effect of the lens 12. Illustratively, the number of the protrusions 124 is two, and the two protrusions 124 are respectively disposed opposite to the two sliding rods 14, so as to achieve the best limiting effect on the carrier 13.

In this embodiment, the protrusion 124 is made of plastic material. When the carrier 13 rocks because of external disturbance, this arch 124 can prevent through the collision is spacing that the carrier 13 from rocking too big, simultaneously because protruding 124 adopts plastic material to make, can not cause the damage to the structure of carrier 13 in the in-process that lies in the carrier 13 collision.

Referring to fig. 16 and 17, fig. 16 is a schematic structural diagram of the carrier 13 and the lens 12 in the structure shown in fig. 8. Fig. 17 is an exploded view of the structure shown in fig. 16.

In this embodiment, the carrier 13 has a hollow structure with two open ends. The carrier 13 includes an upper surface 132, a lower surface 133, a front surface 134, and a rear surface 135. Upper surface 132 and lower surface 133 are oppositely disposed and front surface 134 and rear surface 135 are oppositely disposed. Two openings at two ends of the carrier 13 are formed on the front surface 134 and the rear surface 135, respectively, the lens 12 is fixed in the space enclosed by the carrier 13, and one end of the lens 12 at the object side is exposed out of the front surface 134, and one end of the lens 12 at the image side is exposed out of the rear surface 135. In this embodiment, the lens 12 may be fixed to the carrier 13 by a colloid 16.

Referring to fig. 17, the lens 12 may include a lens barrel 126 and at least one lens fixed inside the lens barrel 126. For example, the number of the lenses may be multiple, and the optical axes of the multiple lenses are overlapped to combine into a lens group, so as to have better optical performance. The lens barrel 126 is fixed to the carrier 13 by spot gluing. In this embodiment, the surface of the lens barrel 126 is provided with one or more bosses 127, the bosses 127 are wrapped by glue when the lens 12 is fixed on the carrier 13 by glue, and after the glue is cured, the spacing between the bosses 127 and the glue prevents the lens 12 from loosening along the axial direction of the optical axis, so as to enhance the bonding strength between the lens 12 and the carrier 13.

As shown in fig. 16, the slide groove 131 is formed in the lower surface 133. In this embodiment, the number of the sliding grooves 131 is two, for convenience of understanding, the two sliding grooves are respectively a sliding groove 131a and a sliding groove 131b, the sliding grooves 131a and the sliding grooves 131b are arranged on the lower surface 133 at intervals, and the sliding grooves 131a and the sliding grooves 131b are in one-to-one corresponding fit with the two sliding rods 14 (fig. 14). The sliding groove 131a is in an inverted trapezoid shape, two side walls of the sliding groove 131a contact the sliding rod 14 to achieve fine positioning with the sliding rod 14, and the carrier 13 can only move in the axial direction of the sliding rod 14, so that the moving direction of the carrier 13 relative to the sliding rod 14 is limited. The sliding groove 131b is bowl-shaped, and the bottom wall of the sliding groove 131b contacts the sliding rod 14, so that the sliding groove is adapted to the assembly tolerance between the sliding groove and the sliding rod 14 in the assembly process, and the reliable matching between the carrier 13 and the sliding rod 14 is ensured. Of course, in other embodiments, the shapes of the two sliding grooves may also be other shapes such as a "V" shape, as long as the carrier 13 can be limited from moving axially on the sliding rod 14, and a tolerance can be provided for the assembly between the sliding grooves and the sliding rod 14.

Referring to fig. 18A, 18B and 18C, fig. 18A is a schematic structural view of the structure shown in fig. 16 at another angle. Fig. 18B is a partial structural schematic view of the structure shown in fig. 9. Fig. 18C is a partial structural schematic view of the structure shown in fig. 14.

In some embodiments, the middle of the groove wall of the sliding groove is provided with an avoiding groove, and the avoiding groove 136 is used for avoiding the middle of the sliding groove 131 from contacting the sliding rod 14. For convenience of understanding, the avoiding grooves formed in both side walls of the slide groove 131a are avoiding grooves 136a, and the avoiding grooves formed in the bottom wall of the slide groove 131b are avoiding grooves 136b. It can be understood that only two ends of the sliding groove 131B (the sliding groove 131 a) are in contact fit with the sliding rod 14 (as shown in fig. 18B), and the other places are not in contact with the sliding rod 14 (as shown in fig. 18C), so that the problems that the carrier 13 is unsmooth and poor in stability in the moving process due to too large contact area and too large friction of the carrier 13 and the sliding rod 14 are prevented, and the problem that the carrier 13 is poor in stability in the moving process due to poor flatness of the contact surface of the carrier 13 and the sliding rod 14 is also avoided.

Referring to fig. 14 and 16, the upper surface 132 is provided with a limiting groove 1321, i.e. the surface of the carrier 13 facing away from the sliding groove 131 is provided with a limiting groove 1321. The retaining groove 1321 is configured to engage with the protrusion 124 of the cover 11B. In this embodiment, the retaining slot 1321 is recessed in the upper surface 132. The number of the limiting grooves 1321 is two, the two limiting grooves 1321 are respectively arranged corresponding to the two sliding grooves 131, and the two protrusions 124 on the cover body 11B are arranged in the two limiting grooves 1321 in a one-to-one correspondence manner. When the carrier 13 shakes due to external interference, the limiting groove 1321 prevents the carrier 13 from shaking too much by matching with the protrusion 124 to limit the carrier 13. It will be appreciated that the length of the spacing slot 1321 is long enough to ensure that the spacing slot 1321 does not interfere with the protrusion 124 to affect the movement of the carrier 13 during the movement of the carrier 13.

Referring to fig. 17 and 19, fig. 19 is a schematic cross-sectional view of the structure shown in fig. 7 along the direction D-D.

The carrier 13 further includes flexible anti-collision blocks 137, the flexible anti-collision blocks 137 are disposed on two sides of the carrier 13 in the optical axis direction of the lens 12, and the flexible anti-collision blocks 137 may be fixed to the carrier 13 by adhesion. By arranging the flexible anti-collision blocks 137 at two sides of the carrier 13 in the optical axis direction of the lens 12, when the carrier 13 moves in the optical axis direction or collides with the housing 11 in a reliability test, the flexible anti-collision blocks 137 can absorb deformation impact energy, and reduce damage to the carrier 13 caused by collision impact. Of course, in other embodiments, the flexible bumper block 137 may also be secured to the carrier 13 by an insert molding process or by a snap fit or the like.

Illustratively, the number of the flexible crash blocks 137 is four, two flexible crash blocks 137 are spaced apart from each other on the front surface 134, and two flexible crash blocks 137 are spaced apart from each other on the rear surface 135. Specifically, the front surface 134 includes two first grooves, and the two flexible anti-collision blocks 137 are fixed in the two first grooves in a one-to-one correspondence manner. The rear surface 135 includes two second grooves, and the two flexible anti-collision blocks 137 are fixed in the two second grooves in a one-to-one correspondence. It will be appreciated that the flexible impact pads 137 are embedded in the front and

rear surfaces

134, 135 of the carrier 13 to provide a more secure attachment to the carrier 13.

In this embodiment, the material of the bumper block may be a material having a modulus much smaller than that of the carrier 13, thereby facilitating protection of the carrier 13 and the structure disposed within the carrier 13. For example, when the material of the carrier 13 is a hard plastic, the material of the flexible bumper block 137 may be rubber, silicone, mylar, foam, or other soft deformable material.

As shown in fig. 17 and 19, the carrier 13 further includes a left surface 138 and a right surface 139. It is understood that the left surface 138 and the right surface 139 are respectively located on both sides of the carrier 13 perpendicular to the optical axis direction of the lens 12. The left surface 138 and the right surface 139 are each provided with a receiving groove 140, and the receiving groove 140 is used to receive a part of the driving assembly of the optical lens 10.

As shown in fig. 19, the optical lens 10 further includes a driving assembly 19, and the driving assembly 19 is electrically connected to the circuit board 15, so as to control the driving assembly 19 to drive the carrier 13 to slide relative to the sliding rod 14 through the circuit board 15. Illustratively, the drive unit 19 includes a coil 191 and a magnet 192, the magnet 192 is provided on the carrier 13, the coil 191 is provided on the frame 11A, and the magnet 192 is provided opposite to the carrier 13. The circuit board 15 is electrified by controlling the coil 191, the magnet 192 generates a certain magnetic field at the coil 191, the coil 191 generates a lorentz force in the magnetic field environment, meanwhile, the magnet 192 generates a force in a direction opposite to the direction of the lorentz force balance, and by designing the magnetic pole direction and the strength of the magnet 192 and the current magnitude and the direction of the coil 191, the reaction force borne by the magnet 192 meets the requirement of driving the carrier 13, and further the carrier 13 drives the lens 12 to move towards a specific direction, so that the aim of focusing the lens 12 is fulfilled.

Specifically, referring to fig. 11 and 19, the coil 191 includes a first coil 1911 and a second coil 1912, and the magnets 192 includes a first magnet 1921 and a second magnet 1922. The first coil 1911 is fixed and electrically connected to the first portion 151 of the circuit board 15, and is accommodated in the first avoiding space 1132, that is, the first coil 1911 is disposed inside the first side plate 113. The second coil 1912 is fixed and electrically connected to the second portion 152 of the circuit board 15, and is accommodated in the second avoiding space 1142, i.e. the second coil 1912 is disposed inside the second side plate 114. The first magnet 1921 is disposed in the accommodating groove 140 on one side of the carrier 13 and is disposed opposite to the first coil 1911, and the second magnet 1922 is disposed in the accommodating groove 140 on the other side of the carrier 13 and is disposed opposite to the second coil 1912.

It can be understood that first coil 1911 and second coil 1912 are located the relative both sides of carrier 13, guarantee that carrier 13 atress is balanced, and carrier 13 receives the counter-force of both sides simultaneously and compares in the physical power that only receives one side, and the focusing effect of module 1 of making a video recording is guaranteed in the removal that can be more steady.

In this example, the first coil 1911 is opposite and spaced from the first magnet 1921, and the second coil 1912 is opposite and spaced from the second magnet 1922, so as to have a certain gap to avoid collision interference between the two. The first and

second coils

1911, 1912 may be formed from long wire windings, or the first and

second coils

1911, 1912 may also be micro-circuit board coils formed from the circuit board 15. The first coil 1911 and the second coil 1912 each have two electrical signal ports (which may be either ends of a coil wire or pads or pins of a micro-circuit board coil), the two electrical signal ports of the first coil 1911 being soldered to the first portion 151 of the circuit board 15, and the two electrical signal ports of the second coil 1912 being soldered to the second portion 152 of the circuit board 15.

For ease of understanding, the first coil 1911 is taken as an example for illustration, and two telecommunication ports of the first coil 1911 are defined as port a and port B, respectively. As shown in fig. 20, when the driver chip on the circuit board 15 inputs an electrical signal to the port a, the first coil 1911 may generate a clockwise or counterclockwise current according to the clockwise or counterclockwise direction of the wire/circuit layout, and the current flows out from the port B. Conversely, when the driver chip on the circuit board 15 inputs an electrical signal to the port B, the first coil 1911 may generate a reverse current, and the current flows out from the port a. Therefore, in actual operation, the driving chip of the circuit board 15 can commutate the current of the first coil 1911 as needed.

As shown in fig. 19, in the present embodiment, the first magnet 1921 includes two first sub-magnets arranged in the axial direction of the slider 14, and the magnetic poles of the surfaces of the two first sub-magnets facing the first coil 1911 are different. The second magnet 1922 includes two second sub-magnets arranged in the axial direction of the slider 14, the two second sub-magnets having different magnetic poles on the surface facing the second coil 1912. The magnetic poles of the surfaces of the two first sub-magnets facing the first coil 1911 are the same as the magnetic poles of the surfaces of the two second sub-magnets facing the second coil 1912, so that current is input to the same port of the first coil 1911 and the second coil 1912 to drive the first magnet 1921 and the second magnet 1922 to move due to the reaction force in the same direction.

Of course, in a scenario of another embodiment, the magnetic poles of the faces of the two first sub magnets facing the first coil 1911 and the magnetic poles of the faces of the two second sub magnets facing the second coil 1912 may be different. In yet another example scenario, the first magnet 1921 may also include more than two first sub-magnets and the second magnet 1922 may also include more than two second sub-magnets. In still another scenario of another embodiment, as shown in fig. 21, the first magnet 1921 is a single magnet, the second magnet 1922 is also a single magnet, two magnetic poles of the first magnet 1921 are arranged along the extending direction of the slider 14, and two magnetic poles of the second magnet 1922 are arranged along the extending direction of the slider 14.

Referring to fig. 22 and 23, fig. 22 is a schematic view illustrating a driving process of the coil 191 and the magnet 192 shown in fig. 19. Fig. 23 is another driving process diagram of the coil 191 and the magnet 192 shown in fig. 19.

The first coil 1911 and the first magnet 1921 will be described as an example. In driving the carrier 13 (fig. 19), the first magnet 1921 drives the carrier 13 to move axially along the sliding rod 14 under the reaction force of the lorentz force by applying a positive/negative current to the first coil 1911. In an example, the surface of the first magnet 1921 facing the first coil 1911 is an S-pole and an N-pole from left to right. As shown in fig. 22, when the first magnet 1921 is located on the left side, the driver chip of the circuit board 15 inputs a current from the port B of the first coil 1911 and outputs a current from the port a, so that a clockwise current is formed, in order to drive the first magnet 1921 and the carrier 13 to the right side. The magnetic field of the first magnet 1921 generates a lorentz force to the left in the first coil 1911 that has a clockwise current, and generates a reaction force to the right in the first magnet 1921, thereby pushing the first magnet 1921 and the carrier 13 to the right.

In contrast, as shown in fig. 23, when it is necessary to push the carrier 13 from the right side to the left side, it is only necessary that the driver chip of the circuit board 15 inputs a current from the port a of the first coil 1911 and the port B outputs a current, thereby forming a counterclockwise current. A lorentz force reaction force acting leftward is generated on the first magnet 1921, thereby pushing the first magnet 1921 and the carrier 13 leftward.

It is understood that the second coil 1912 drives the second magnet 1922 in the same manner as the first coil 1911 drives the first magnet 1921, and the description thereof is omitted.

It is understood that the driving chip of the circuit board 15 (fig. 10B) can adjust the current input to the first coil 1911 according to the magnitude of the required counterforce, so as to achieve a desired driving state.

Referring to fig. 14 again, the magnet 192 and the magnetic conductive sheet 18 in this embodiment are disposed opposite to each other. Specifically, the first magnet 1921 and the second magnet 1922 are both arranged opposite to the corresponding magnetic conductive sheet 18, and the carrier 13 for fixing the first magnet 1921 and the second magnet 1922 is firmly adsorbed on the sliding rod 14 due to the adsorption effect of the magnet 192 and the magnetic conductive sheet 18, so that the carrier 13 and the sliding rod 14 are prevented from being loosened during normal operation.

Referring to fig. 17 and 19 again, the optical lens 10 further includes a yoke 193, and the yoke 193 is located in the receiving groove 140 and disposed on a side of the magnet 192 opposite to the coil 191. In this embodiment, the number of the yokes 193 is two, one yoke 193 is provided on the side of the first magnet 1921 facing away from the first coil 1911, and one yoke 193 is provided on the side of the second magnet 1922 facing away from the second coil 1912. In the present invention, the yoke 193 is provided to restrict the distribution of the magnetic lines of force of the first and

second magnets

1921 and 1922, so that the magnetic fields of the first and

second magnets

1921 and 1922 more tend to the corresponding coil 191 side, which contributes to the movement of the lens 12 in the image pickup module 1 having a large stroke.

Referring to fig. 19, 24 and 25, fig. 24 is a diagram showing a positional relationship between the magnet 192 and the displacement sensor shown in fig. 19. Fig. 25 is a graph illustrating the magnetic field strength of the displacement sensor shown in fig. 24 during movement of the carrier 13.

As shown in fig. 19, the optical lens 10 further includes a displacement sensor 21, the displacement sensor 21 is electrically connected to the circuit board 15, and the displacement sensor 21 is used for sensing the displacement change of the carrier 13 to obtain a position signal of the carrier 13, so that the driving chip on the circuit board 15 adjusts the direction and magnitude of the current in the coil 191 according to the position signal of the carrier 13 to change the moving direction of the carrier 13 or change the moving speed of the carrier 13.

Specifically, the number of the displacement sensors 21 is two, and the two displacement sensors 21 are soldered to the first portion 151 of the circuit board 15 and spaced apart from each other in the area surrounded by the first coil 1911, thereby utilizing the area surrounded by the first coil 1911. Meanwhile, the two displacement sensors 21 are disposed in the area surrounded by the first coil 1911 and are also beneficial to be opposite to the first magnet 1921, and the two displacement sensors 21 are respectively used for capturing the magnetic field intensity signals of the two first sub-magnets on the carrier 13 at the position of the displacement sensors 21.

It will be appreciated that when the carrier 13/first magnet 1921 are positioned differently (as in FIG. 24), the magnetic field strength signals detected by the two sensors will be different. The two magnetic field strength signals can be combined into a magnetic field strength signal with good linearity by an algorithm, and the position of the carrier 13 is represented by the magnetic field strength by calibrating the magnitude of the magnetic field strength combined when the carrier 13 is at different positions, as shown in fig. 25. Therefore, the driving chip can control the magnitude and direction of the input current of the first coil 1911 and the second coil 1912 according to the positions of the carrier 13 detected by the two displacement sensors 21, thereby pushing the carrier 13 to travel to/stop at the target position.

The second embodiment: referring to fig. 26 and 27, fig. 26 is a partial schematic structural diagram of another embodiment of the optical lens 10 shown in fig. 8. Fig. 27 is a schematic view of the structure of fig. 26 at another angle.

The optical lens of the present embodiment has substantially the same structure as the optical lens of the first embodiment, except that the structure of the frame 11A and the circuit board 15 of the optical lens 10 in the present embodiment is slightly different, and the way of fixing the two ends of the sliding rod 14 to the frame 11A is different.

Specifically, a surface of the base plate 112 facing away from the first side plate 113 is provided with a groove, the groove forms a fourth accommodating space 110d, and two ends of the fourth accommodating space 110d communicate with the first accommodating space 110a and the second accommodating space 110b. The circuit board 15 includes a first portion 151, a second portion 152, and a third portion 153, and the third portion 153 is connected between the first portion 151 and the second portion 152. The first portion 151 is accommodated in the first accommodating space 110a, and a connecting end of the first portion 151 is bent to extend into the third accommodating space 110c and extends out of the frame body 11A from the avoiding opening 1151 of the third side plate 115. The second portion 152 is received in the second receiving space 110b, and a connecting end of the second portion 152 is bent to extend into the third receiving space 110c and extends out of the frame body 11A from the avoiding opening 1151 of the third side plate 115. The third portion 153 is received in the fourth receiving space 110 d. Of course, in other embodiments, the way in which the circuit board 15 is fixed to the frame body 11A is not limited to the above description.

It is understood that the third portion 153 of the circuit board 15 is accommodated in the groove formed on the substrate 112, so that the thickness of the optical lens 10 in the Z-axis direction is not increased.

Referring to fig. 28, fig. 28 is a partial structural view of the structure shown in fig. 26.

The frame body 11A in this embodiment is not provided with the first fixing portion and the second fixing portion. The optical lens 10 in this embodiment further includes a first pressing member 128 and a second pressing member 129, and both ends of the slide 14 are fixed to the frame body 11A by the first pressing member 128 and the second pressing member 129, respectively. Specifically, the substrate 112 includes two first fixing grooves 1124 and two second fixing grooves 1125, the two first fixing grooves 1124 are located at both sides of the mounting groove 111 and are close to the third side panel 115, and the two second fixing grooves 1125 are located at both sides of the mounting groove 111 and are far away from the third side panel 115. The first pressing member 128 is disposed on a surface of the sliding rod 14 away from the base plate 112, and two ends of the first pressing member 128 are respectively fixed to the corresponding first fixing grooves 1124, and the second pressing member 129 is disposed on a surface of the sliding rod 14 away from the base plate 112, and two ends of the second pressing member 129 are respectively fixed to the corresponding second fixing grooves 1125, so as to fix the sliding rod 14 to the frame 11A.

In this embodiment, the first pressing member 128 and the second pressing member 129 are both pressing plates made of a resilient metal, a relatively thin metal or a plastic. The pressing sheet can be fixed on the base plate 112 by bonding, riveting, buckling, welding and other connection modes, so that the pressing sheet can continuously limit the sliding rod 14 without failure, and the pressing sheet and the sliding rod 14 can also be connected by welding. This embodiment may be designed to continuously press against the slider 14 and apply pressure to the slider 14 to prevent the slider 14 from being released from the base plate 112, depending on the material and structure of the press sheet. Or the pressing sheet and the sliding rod 14 are designed to have a certain small clearance. It will be appreciated that the small gap is small enough to prevent a large displacement of the slide 14.

Of course, in other embodiments, as shown in FIG. 29, the first pressing member 128 and the second pressing member 129 may be press blocks, which may be made of metal or plastic. The first pressing member 128 and the second pressing member 129 may be fixed on the base plate 112 by bonding, riveting, snapping, etc. so that the first pressing member 128 and the second pressing member 129 continuously limit the slide 14 without failure, and the pressing member and the slide 14 may be bonded.

The third embodiment: referring to fig. 30 and 31, fig. 30 is a schematic structural diagram of another embodiment of the optical lens 10 shown in fig. 7. Fig. 31 is an exploded structural schematic diagram of the optical lens 10 shown in fig. 30.

The optical lens 10 in this embodiment has substantially the same structure as the optical lens 10 in fig. 7, except that the optical lens 10 in this embodiment has different numbers of the first coil 1911, the second coil 1912, the first magnet 1921, and the second magnet 1922, and the number of the displacement sensors 21 in this embodiment is one. In addition, the driving logic of the coil 191 by the driving chip of the circuit board 15 is also different.

Specifically, the number of the first coils 1911 and the number of the second coils 1912 are both two, and the number of the corresponding first magnets 1921 and second magnets 1922 (fig. 32) is also two. The two first coils 1911 are disposed at intervals in the extending direction of the slider 14 and are both accommodated in the first escape space 1132, and the two second coils 1912 are disposed at intervals in the extending direction of the slider 14 and are both accommodated in the second escape space 1142. The two first coils 1911 are opposite to and spaced from the two first magnets 1921, and the two second coils 1912 are opposite to and spaced from the two second magnets 1922, so as to leave a certain gap to avoid collision and interference between the two.

As the number of the coils 191 increases, the sizes of the corresponding first and

second avoidance spaces

1132 and 1142 become larger. Part of the electronic components are disposed on the surface of the circuit board 15 opposite to the first side plate 113, and the cover 11B is provided with an avoiding opening 130 to avoid the electronic components on the circuit board 15. Of course, in other embodiments, the number of the first coil 1911 and the number of the second coil 1912 may be multiple, and the number of the first magnet 1921 and the number of the second magnet 1922 may correspond to the first coil 1911 and the second coil 1912, respectively.

Referring to fig. 32, fig. 32 is a schematic cross-sectional view of the structure shown in fig. 30 along the direction E-E.

In this embodiment, the two first magnets 1921 are arranged in the axial direction of the slider 14, and the two second magnets 1922 are arranged in the axial direction of the slider 14. The magnetic poles of the two first magnets 1921 facing the surface of the first coil 1911 are staggered, and the magnetic poles of the two second magnets 1922 facing the surface of the second coil 1912 are staggered, so that the energized first coil 1911 and second coil 1912 can drive the carrier 13 to move in the extending direction of the slider 14.

Referring to fig. 33 and 34, fig. 33 is a positional relationship diagram of the magnet 192 and the displacement sensor 21 having the structure shown in fig. 32. Fig. 34 is a graph showing the magnetic field strength of the displacement sensor 21 shown in fig. 33 during movement of the carrier 13.

In this embodiment, the displacement sensor 21 is provided between the two first coils 1911. In the moving process of the first magnet 1921, the magnetic field intensity signals received by the displacement sensor 21 are as shown in fig. 34, and the driving chip can obtain the position of the carrier 13 according to the magnetic field intensity received by the displacement sensor 21 by calibrating the displacement sensor 21 in sections. According to the method and the device, the displacement sensor 21 is calibrated in a segmented mode, and the function of sensing the long-stroke module by the single displacement sensor 21 is achieved. Meanwhile, the number of the displacement sensors 21 in the embodiment is one, so that the cost caused by the number of the displacement sensors 21 is reduced, and compared with a scheme that the number of the displacement sensors is two or more, the error of signal processing between the two displacement sensors is avoided.

In other embodiments, as shown in FIG. 35, when the number of the first coils 1911 is three, the number of the corresponding first magnets 1921 is three. In this case, the displacement sensor 21 is provided in an area surrounded by the first coil 1911 in the middle. During the movement of the first magnet 1921, the magnetic field strength signals received by the displacement sensor 21 are as shown in fig. 36, and the driving chip can obtain the position of the carrier 13 according to the magnetic field strength received by the displacement sensor 21 by calibrating the displacement sensor 21 in sections. Of course, the number of the first coils 1911 may be three or more, and the number of the corresponding first magnets 1921 may be three or more.

Referring to fig. 37, 38, 39 and 40, fig. 37 is a schematic view showing a driving process of the coil 191 and the magnet 192 shown in fig. 32. Fig. 38 is another driving process diagram of the coil 191 and the magnet 192 shown in fig. 32. Fig. 39 is a schematic view showing another driving process of the coil 191 and the magnet 192 shown in fig. 32. Fig. 40 is another driving process diagram of the coil 191 and the magnet 192 shown in fig. 32.

As shown in fig. 37, the first coil 1911 is described as an example for easy understanding. The two first coils 1911 are a first coil 1911a and a first coil 1911b, respectively. For convenience of description, the two telecommunication ports of the first coil 1911a are defined as port A1 and port A2, respectively, and the two telecommunication ports of the first coil 1911B are defined as port B1 and port B2, respectively. The first coil 1911a and the first coil 1911b both operate independently in circuit logic, when the first coil 1911a is energized, the first coil 1911b may be in an energized or non-energized state, and the current levels of the first coil 1911a and the first coil 1911b and the telecommunication port of the current input may also be adjusted independently.

When the driver chip inputs an electrical signal to the port A1, the first coil 1911a may generate a clockwise or counterclockwise current according to the clockwise or counterclockwise direction of the wire/circuit layout, and the current flows out from the port A2. On the contrary, when the driver chip inputs an electrical signal to the port A2, the first coil 1911a may generate a reverse current, and the current flows out from the port A1. Similarly, this logic is also applied to the ports B1 and B2 of the first coil 1911B. Therefore, in actual operation, the driving chip can commutate the current of the coil 191 as required.

Next, a driving process of the coil 191 and the magnet 192 will be described by taking the first coil 1911 and the first magnet 1921 as an example.

In the process of driving the carrier 13, the driving chip obtains the position of the carrier 13 through the displacement sensor 21, further determines that the first coil 1911a or the first coil 1911b should be selected to be powered on, determines the magnitude and direction of the electrical signal, and outputs the electrical signal to the target coil, thereby pushing the corresponding magnet 192 and the carrier 13 to move/stop to the next position. When the carrier 13 moves to the next position, the driving chip determines the relationship between the position and the target position again by the displacement sensor 21, thereby determining whether to switch the current magnitude and direction of the energized coil and the input coil, and outputs a relevant electric signal to the target coil, thereby continuing to push/stop the movement of the moving member. According to the logic, the driving chip outputs a certain current magnitude and direction to the target coil for multiple times according to multiple feedbacks of the displacement sensor 21, so that the carrier 13 moves or stops to the target position, the target coil may be the first coil 1911a or the first coil 1911B, the current input may be at the port A1, the port A2, the port B1 or the port B2, and the current magnitude is also adjusted continuously according to actual requirements.

As shown in fig. 33, taking the first magnet 1921 and the carrier 13 traveling to the left as an example, when the position of the first magnet 1921 is stage 1, the driving chip selects the first coil 1911b as the driving coil, and the first coil 1911a has no current. When a current is input from B1, the first coil 1911B generates a clockwise current, and the first coil 1911B receives a lorentz force to the right, thereby generating a reaction force to the left at the first magnet 1921, and driving the first magnet 1921 and the carrier 13 to move to the left. On the other hand, when a current is input from B2, the first magnet 1921 and the carrier 13 move rightward.

As shown in fig. 38, when the position of the first magnet 1921 is at stage 2, the driving chip selects the first coil 1911a as the driving coil, and the first coil 1911b has no current. When a current is input from A2, the first coil 1911a forms a counterclockwise current, and the first coil 1911a receives a lorentz force to the right, thereby forming a reaction force to the left at the first magnet 1921, and driving the first magnet 1921 and the carrier 13 to move to the left. Conversely, when a current is input from A1, the first magnet 1921 and the carrier 13 can move rightward.

As shown in fig. 39, when the position of the first magnet 1921 is at stage 3, the driving chip selects the first coil 1911b as the driving coil, and the first coil 1911a has no current. When a current is input from B2, the first coil 1911B generates a counterclockwise current, and the first coil 1911B receives a lorentz force to the right, thereby generating a reaction force to the left at the first magnet 1921, and driving the first magnet 1921 and the carrier 13 to move to the left. On the other hand, when a current is input from B1, the first magnet 1921 and the carrier 13 move rightward.

As shown in fig. 40, when the position of the first magnet 1921 is in stage 4, the driving chip selects the first coil 1911a as the driving coil, and the first coil 1911b has no current. When a current is input from A1, the first coil 1911a forms a clockwise current, and the first coil 1911a receives a lorentz force to the right, so that a reaction force to the left is formed at the first magnet 1921, thereby driving the first magnet 1921 and the carrier 13 to move to the left. Conversely, when the current is input from A2, the first magnet 1921 and the carrier 13 can move rightward.

It is understood that the second coil 1912 drives the second magnet 1922 in the same manner as the first coil 1911 drives the first magnet 1921, and the description thereof is omitted. The driving chip of the circuit board 15 can adjust the current input to the first coil 1911 according to the magnitude of the required reaction force, thereby achieving an ideal pushing state. In this embodiment, the two first coils 1911 and the two second coils 1912 are supplied with power in a staggered manner, so that the reaction force level is stable under the condition of equal current input, and the driving chip is more convenient to control and adjust.

The fourth embodiment: referring to fig. 41, 42 and 43, fig. 41 is a schematic structural diagram of another embodiment of the optical lens 10 shown in fig. 7. Fig. 42 is an exploded structural schematic diagram of the optical lens 10 shown in fig. 41. Fig. 43 is an exploded view of a portion of the structure shown in fig. 42.

The optical lens 10 in this embodiment has substantially the same structure as the optical lens 10 in fig. 7, except that the coil in this embodiment further includes a third coil 1913, the magnets further include a third magnet 1923 (fig. 44), the frame 11A and the circuit board 15 have slightly different structures, and the driving logic of the driving chip of the circuit board 15 for the coil 191 is different.

Specifically, as shown in fig. 42 and 43, a surface of the base plate 112 facing away from the first side plate 113 is provided with a groove, the groove forms a fourth accommodating space 110d, and two ends of the fourth accommodating space 110d communicate with the first accommodating space 110a and the second accommodating space 110b. The circuit board 15 includes a first portion 151, a second portion 152, and a third portion 153, and the third portion 153 is connected between the first portion 151 and the second portion 152. The first portion 151 is accommodated in the first accommodating space 110a, and a connecting end of the first portion 151 bends and extends to the third accommodating space 110c and extends out of the frame body 11A from the relief opening 1151 of the third side plate 115. The second portion 152 is received in the second receiving space 110b, and a connecting end of the second portion 152 is bent to extend into the third receiving space 110c and extends out of the frame body 11A from the avoiding opening 1151 of the third side plate 115. The third portion 153 is received in the fourth receiving space 110 d. Of course, in other embodiments, the way in which the circuit board 15 is fixed to the frame body 11A is not limited to the above description.

Referring to fig. 42, 44 and 45, fig. 44 is a schematic cross-sectional view along the direction F-F of fig. 41. FIG. 45 is a schematic view of a portion of the structure shown in FIG. 42 at another angle.

Specifically, the middle portion 1121 of the substrate 112 is further provided with a third avoiding space 1126 communicating with the fourth accommodating space 110d, and the third coil 1913 is accommodated in the third avoiding space 1126 and electrically connected to the third portion 153 of the circuit board 15. The third magnet 1923 is disposed on the lower surface 133 of the carrier 13, and the third magnet 1923 is disposed opposite to and spaced apart from the third coil 1913 with a gap therebetween to avoid collision and interference therebetween.

It is understood that the structure of the third coil 1913 is the same as that of the first coil 1911, and thus, the description thereof is omitted. The third magnet 1923 has only a single magnetic pole on the face opposite to the third coil 1913, and the other magnetic pole on the opposite face. For example, the N-pole of the third magnet 1923 may face the third coil 1913, and the S-pole of the third magnet 1923 may face the third coil 1913, and the N-pole of the third magnet 1923 may face the third coil 1913. Since the third magnet 1923 is much smaller in width than the third coil 1913, when the carrier 13 travels until the third magnet 1923 is aligned with a single side of the third coil 1913, the single side of the energized third coil 1913 may magnetically push the third magnet 1923, thereby pushing the carrier 13 to travel.

Referring to fig. 46, 47 and 48, fig. 46 is a schematic view showing a driving process of the coil 191 and the magnet 192 shown in fig. 44. Fig. 47 is another driving process diagram of the coil 191 and the magnet 192 shown in fig. 44. Fig. 48 is a schematic view showing another driving process of the coil 191 and the magnet 192 shown in fig. 44.

Next, a description will be given of a driving process of the coil 191 and the magnet 192 by taking the first coil 1911, the first magnet 1921, and the third coil 1913 and the third magnet 1923 as examples.

In the process of driving the carrier 13, the driver chip determines the position of the carrier 13 based on the displacement sensor 21, and determines whether or not a current of a predetermined magnitude is applied to the first coil 1911 in the clockwise/counterclockwise direction, and the applied first coil 1911 generates a lorentz force under the magnetic field of the first magnets 1921, thereby generating a reaction force on the first magnets 1921 side. The first magnet 1921 drives the carrier 13 to move axially along the slider 14 in response to the reaction force of the lorentz force.

At the same time, the driver chip determines whether to activate the third coil 1913 according to the position of the carrier 13 provided by the displacement sensor 21. When the carrier 13 designed in the optical lens 10 has a large stroke, and the reaction force provided by the coils 191 (the first coil 1911 and the second coil 1912) on the two sides at the end of the stroke is not enough to push the carrier 13 to move, the driving chip supplies a certain amount of positive/counterclockwise current to the third coil 1913, thereby pushing the third magnet 1923 and the carrier 13 to move. Thus, at the end of travel, the third coil 1913 operates in place of the first and

second coils

1911, 1912, thereby ensuring that the carrier 13 moves normally during large strokes.

Illustratively, the driving chip determines that the position of the carrier 13 is in stage 1, stage 2 or stage 3 through the displacement sensor 21, and adjusts the output electrical signals of the coils 191 according to the stage in which the position of the carrier 13 is as follows:

as shown in fig. 46, in stage 1, the relative position of the first coil 1911 and the first magnet 1921 is relatively shifted. At this time, when the first coil 1911 is energized, the generated electromagnetic force is insufficient or the generated displacement is small. At this time, the third coil 1913 and the third magnet 1923 are in the facing position, so that the driving chip energizes the third coil 1913 and deenergizes the first coil 1911, the third coil 1913 generates a lorentz force under the action of the magnetic field of the third magnet 1923, and a reaction force is generated at the third magnet 1923 to push the carrier 13 to move.

It is understood that, during the displacement in phase 1, the left portion of the third coil 1913 is within the N-pole range of the third magnet 1923, and the third coil 1913 is energized, the current flowing in the left side of the third coil 1913 is directed inward perpendicular to the drawing plane, the current flowing in the right side of the third coil 1913 is directed outward perpendicular to the drawing plane, as determined by the left hand rule, the left electromagnetic force (the same lorentz force) is applied to the left side of the third coil 1913, and the reaction force, i.e., the right force, is applied to the third magnet 1923, so as to push the carrier 13 to move rightward.

Since the left side of the third coil 1913 is always opposed to the N-pole of the third magnet 1923 in stage 1, the direction of the force generated on both sides of the third coil 1913 does not change. However, the first coil 1911 and the first magnet 1921 are seen from the left to the right, the left side of the first coil 1911 is changed from being opposite to the N pole to being opposite to the S pole, if the stage 1 is used for electrifying the first coil 1911 and the current direction is not changed, the direction of the electromagnetic force generated by the first coil 1911 and the first magnet 1921 is changed, which is not beneficial to controlling the smooth movement of the carrier 13, and therefore, in order to control the smooth movement of the carrier 13, the stage 1 is only used for electrifying the third coil 1913.

As shown in fig. 47, in stage 2, the first coil 1911 is directly opposite to the first magnet 1921, and the third coil 1913 and the third magnet 1923 are not directly opposite. If the third coil 1913 is energized, the resulting thrust is small. So at this time the driver chip energizes the first coil 1911 and de-energizes the third coil 1913. The first coil 1911 generates a lorentz force under the action of the magnetic field of the first magnet 1921, and generates a reaction force at the first magnet 1921 to push the carrier 13 to move.

It can be understood that, during the displacement in the whole stage 2, the left and right portions of the first coil 1911 are within the range of the S-pole and the N-pole of the first magnet 1921, respectively, at this time, the first coil 1911 is energized, the current direction is clockwise, and according to the left-hand rule, the left electromagnetic force (the same lorentz force) is applied to the left side of the first coil 1911, the left electromagnetic force is applied to the right side of the first coil 1911, and the N-pole and the S-pole of the first magnet 1921 are both subjected to the reaction force of the electromagnetic force, that is, the right force, so as to push the carrier 13 to move rightward.

Since the N-pole of the third magnet 1923 initially faces the left side of the third coil 1913 and then faces the right side of the third coil 1913 in step 2, if the third coil 1913 is energized in step 2 and the direction of the current is not changed, the direction of the electromagnetic force generated by the third coil 1913 and the third magnet 1923 changes, which is not favorable for controlling the stable movement of the carrier 13. Therefore, to control the carrier 13 to move smoothly, stage 2 energizes only the first coil 1911.

As shown in FIG. 48, in stage 3, first coil 1911 is not directly opposite first magnet 1921, and third coil 1913 is directly opposite third magnet 1923. When the first coil 1911 is energized, the reaction force to be exerted is small or the displacement to be generated is small. Therefore, at this time, the driver chip energizes the third coil 1913, and deenergizes the first coil 1911, and the third coil 1913 generates a lorentz force under the magnetic field of the third magnet 1923, and generates a reaction force at the third magnet 1923, thereby moving the carrier 13.

It is understood that during the entire stage 3 displacement, the right portion of the third coil 1913 is within the N-pole range of the third magnet 1923, and the third coil 1913 is energized. The current direction on the left side of the third coil 1913 is perpendicular to the drawing surface and goes out, and the current direction on the right side of the third coil 1913 is perpendicular to the drawing surface and goes in, so that the left side of the third coil 1913 receives the electromagnetic force (the same lorentz force) on the left side, and the third magnet 1923 receives the reaction force of the electromagnetic force, that is, the force on the right side, as determined by the left hand rule. To push the carrier 13 to the right.

In stage 3, the right side of the third coil 1913 is always opposed to the N-pole of the third magnet 1923, and thus the direction of the force generated on both sides of the third coil 1913 does not change. However, as can be seen from the left to right figures, if the right side of the first coil 1911 is changed from being opposite to the N pole to being opposite to the S pole, and if the first coil 1911 is electrified in the stage 3 and the current direction is not changed, the direction of the electromagnetic force generated by the first coil 1911 and the first magnet 1921 is changed, which is not beneficial to controlling the smooth movement of the carrier 13, so that the stage 3 is only electrified on the third coil 1913 to control the smooth movement of the carrier 13.

Similarly, when the carrier 13 needs to be driven reversely, the input port of the electrical signal is adjusted.

The driving assembly 19 of this embodiment includes a third magnet 1923 and a third coil 1913, and the third magnet 1923 and the third coil 1913 are in relay fit with the first coil 1911 and the first magnet 1921 (the second coil 1912 and the second magnet 1922), so that the driving stroke of the carrier 13 can be increased, and the carrier 13 can be moved in a larger stroke range.

Of course, in other embodiments, the number of the first coils 1911 and the second coils 1912 in the present embodiment may be two or more, and correspondingly, the number of the first magnets 1921 and the second magnets 1922 may be two or more.

The protection scope of the present application is not limited to the first to fourth embodiments, and any combination of the first to fourth embodiments is also within the protection scope of the present application, that is, the above-described embodiments may be combined arbitrarily according to actual needs.

The above embodiments and embodiments of the present application are only examples and embodiments, and the scope of the present application is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present application, and all the changes or substitutions should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
