The technical solution of the present application will be further described with reference to the following embodiments and the accompanying drawings.

The first aspect of the embodiments of the present application discloses a carrier, which can be applied to a driving device to be used as a carrier of the driving device. The driving device is a mechanism for driving the lens assembly of the camera module to move. Specifically, referring to fig. 1 to 3, the carrier according to the embodiment of the present application may be applied to a driving device, the driving device may include an elastic component, the carrier 10 may include a body 11, a through first mounting hole 11a is formed on the body 11, and the first mounting hole 11a may be used for mounting a lens assembly of a camera module. The body 11 is further provided with a first bump 11b and a second bump 11c, the first bump 11b is arranged near the periphery of the first mounting hole 11a, the second bump 11c is arranged near the outer peripheral surface of the body 11, and a limiting space 11d for limiting the elastic component is formed between the second bump 11c and the first bump 11 b.

The first bump 11b and the second bump 11c are arranged on the body 11 of the carrier 10, the first bump 11b is arranged close to the periphery of the first mounting hole 11a, and the second bump 11c is arranged close to the outer peripheral surface 11e of the body 11, so that a limiting space 11d for limiting the elastic component can be formed between the first bump 11b and the second bump 11c, when the carrier 10 is applied to a driving device, when the elastic component of the driving device is connected to the carrier 10, the elastic component can not displace relative to the carrier 10 due to the limiting effect of the limiting space 11d, thereby realizing the positioning and limiting of the elastic component, preventing the elastic component from displacing when the elastic component is bonded with the carrier 10, and effectively improving the accuracy of the bonding position when the elastic component is bonded with the carrier 10.

In some embodiments, the carrier 10 may have a substantially polygonal shape as a whole, and the first mounting hole 11a may be opened at a middle portion thereof, and a center of the first mounting hole 11a may be located on an optical axis of the lens assembly. Specifically, in order to facilitate mounting of the lens module, the inner wall surface of the first mounting hole 11a may be provided with an internal thread 110, and the lens module may be mounted in the first mounting hole 11a by means of a screw connection. The lens assembly is connected with the first mounting hole 11a in a threaded connection mode, and the mounting mode is simpler and faster.

Further, when the first bump 11b and the second bump 11c are disposed on the carrier 10, the first bump 11b and the second bump 11c may be disposed at intervals along the surrounding direction of the center of the first mounting hole 11a, so that the second bump 11c and the first bump 11b are disposed on the body 11 of the carrier 10 in a staggered manner, and thus the limiting space 11d can be formed along the surrounding direction of the center of the first mounting hole 11a, thereby realizing the limiting arrangement of the elastic component.

Further, as can be seen from the foregoing, the first protrusion 11b is disposed adjacent to the periphery of the first mounting hole 11a, and the second protrusion 11c is disposed adjacent to the outer peripheral surface 11e of the body 11 of the carrier 10, and the first protrusion 11b and the second protrusion 11c are spaced apart from each other in the surrounding direction of the center of the first mounting hole 11a, so that the limiting space 11d formed between the first protrusion 11b and the second protrusion 11c can be an arc-shaped or annular limiting space 11d, and the limiting effect on the elastic component is better.

Further, the first bumps 11b and the second bumps 11c may be a plurality of, the first bumps 11b may be arranged along the center of the first mounting hole 11a at intervals in a ring shape, the second bumps 11c may be arranged along the center of the first mounting hole 11a at intervals in a ring shape, and one second bump 11c may be arranged between every two adjacent first bumps 11 b. By adopting the arrangement of the first bumps 11b and the second bumps 11c and arranging the second bump 11c between two adjacent first bumps 11b, an annular limiting space 11d can be formed on the carrier 10, so that the elastic component is effectively limited.

For example, taking four first and

second bumps

11b and 11c as an example, the four first and

second bumps

11b and 11c may be arranged at intervals along the center of the first mounting hole 11a, and one second bump 11c is arranged between every two first bumps 11b, and the four first bumps 11b are all arranged on one side of the body 11 close to the periphery of the first mounting hole 11a, and the four second bumps 11c are all arranged on one side of the body 11 close to its own outer peripheral surface 11e, so that an annular limiting space 11d (shown by a dashed circle in fig. 2 and 3) centered on the center of the first mounting hole 11a is formed on the body 11. It is to be understood that the above-mentioned examples regarding the number of the first bumps 11b and the second bumps 11c for easy understanding do not limit the scope of the present embodiment, that is, in the actual setting, the number of the first bumps 11b and the second bumps 11c can be adjusted according to the actual situation.

It is understood that, in the surrounding direction of the center of the first mounting hole 11a, the interval between the second protrusion 11c and the first protrusion 11b can be set according to practical situations, and also taking the first protrusion 11b and the second protrusion 11c as an example, the angle (i.e. the central angle α) formed between the line connecting the second protrusion 11c to the center of the first mounting hole 11a and the line connecting the first protrusion 11b to the center of the first mounting hole 11a can be approximately 20 ° -70 °. For example, the central angle β between two adjacent first protrusions 11b is 90 °, and the central angle α between a second protrusion 11c located between two adjacent first protrusions 11b and an adjacent first protrusion 11b may be 45 °. Of course, in other embodiments, the central angle α between the second bump 11c and the adjacent first bump 11b between two adjacent first bumps 11b may also be 20 °, 30 °, 40 °, 50 °, 60 °, or 70 °. It should be noted that, in two adjacent first bumps 11b, the central angle from the second bump 11c located between the two adjacent first bumps 11b to one of the first bumps 11b and the central angle from the second bump 11c to the other first bump 11b may be the same or different.

As shown in fig. 4 to 6, the first bump 11b and the second bump 11c may be strip bumps, and the height of the first bump 11b protruding from the body 11 may be slightly less than or equal to the height of the second bump 11c protruding from the body 11. The first bump 11b has a first surface 111, the second bump 11c has a second surface 112, and the surface area of the second surface 112 is larger than that of the first surface 111. It is contemplated that the carrier 10 is used to carry the lens assembly and when the carrier 10 is applied to the driving device, it can move relative to the base of the driving device, so as to move the lens assembly relative to the base, so as to achieve focusing or focusing of the lens assembly. Thus, the second projection on the carrier 10 can be used for abutting or striking against the base or the housing of the drive device when moving relative to the base, e.g. when the face of the body 11 intended to face the base is provided with the first projection and the second projection, and the protruding height H1 of the first projection 11b is slightly smaller than the protruding height H2 of the second projection 11c, then the second projection 11c can be used for abutting or striking against the base when the carrier 10 moves relative to the base to abut against the base, and when the face of the body 11 intended to face the housing is provided with the first projection 11b and the second projection 11c, then the second projection 11c can be used for abutting or striking against the base when the carrier 10 moves relative to the base to abut against the housing. Thus, when the surface area of the second surface 112 of the second bump 11c is larger than the surface area of the first surface 111 of the first bump 11b, the larger the surface area of the second bump 11c for abutting or impacting with the base or the housing, the lower the risk of generating chips due to impact, and at the same time, the pressure of the carrier 10 when impacting the housing or the base can be reduced, thereby effectively reducing the risk of generating chips due to impact. Of course, the protrusion height H1 of the first protrusion 11b may be substantially equal to the protrusion height H2 of the second protrusion 11c, so that not only the second protrusion 11c may be used to abut or impact with the base or the housing, but also the first protrusion 11b may be used to abut or impact with the base or the housing, thereby further increasing the surface area of the carrier 10 that abuts or impacts with the base or the housing, and further reducing the risk of debris being generated when the carrier 10 impacts with the base or the housing.

Further, in the surrounding direction of the center of the first mounting hole 11a, the length of the first protrusion 11b is smaller than that of the second protrusion 11c, for example, the length of the second protrusion 11c may be approximately 1.5-3 times the length of the first protrusion 11b, so that not only the limiting space 11d formed between the first protrusion 11b and the second protrusion 11c may be increased, but also the surface area of the second surface 112 may be increased, thereby further increasing the impact area and reducing the risk of generating debris due to impact.

Referring to fig. 1 to 3 again, in some embodiments, the carrier 10 is generally octagonal, and includes a first surface 12 and a second surface 13 opposite to each other, the first mounting hole 11a may penetrate from the first surface 12 to the second surface 13, and the first protrusion 11b and the second protrusion 11c are disposed on the first surface 12 and/or the second surface 13. Specifically, when the lens block is mounted in the first mounting hole 11a of the carrier 10, the first surface 12 and the second surface 13 are two surfaces along the optical axis direction of the lens block. That is, when the first bump 11b and the second bump 11c are provided, the elastic member may be provided on the first surface 12, the second surface 13, or both the first surface 12 and the second surface 13, so that the elastic member may be restrained by the restraining space 11d formed between the first bump 11b and the second bump 11c, regardless of whether the elastic member is connected to the first surface 12 of the carrier 10 or the elastic member is connected to the second surface 13 of the carrier 10. For example, as shown in fig. 2, fig. 2 shows that the first bumps 11b, the second bumps 11c are provided on the second surface 13, while, as shown in fig. 3, fig. 3 shows that the first bumps 11b, the second bumps 11c are provided on the first surface 12.

In some embodiments, when the first surface 12 is provided with the first bump 11b and the second bump 11c, the first surface 12 may further be provided with a first glue groove 14, the first glue groove 14 may be disposed corresponding to the first bump 11b, and the first glue groove 14 may be located on a side of the first bump 11b away from the first mounting hole 11a, the first glue groove 14 may be used for glue dispensing to achieve connection between the elastic component and the carrier 10, and the first bump 11b may also be used for blocking glue in the first glue groove 14 from overflowing to the first mounting hole 11 a. Specifically, the number of the first glue grooves 14 may be one or more, when the number of the first glue grooves 14 is multiple, the multiple first glue grooves 14 may be disposed at intervals, and meanwhile, in the projection of the first surface 12, the multiple first glue grooves 14 are all located on one side of the first bump 11b, which is away from the first mounting hole 11a, so that, when glue is dispensed in the first glue groove 14, since the first bump 11b protrudes relative to the first surface 12, glue overflowing from the first glue groove 14 can not overflow into the first mounting hole 11a due to blocking of the first bump 11b, thereby preventing the glue from overflowing into the lens assembly in the first mounting hole 11a and preventing the lens assembly from being polluted.

Further, the first bump 11b has a third surface 113 and a fourth surface 114 opposite to each other, the third surface 113 is flush with the inner wall surface of the first mounting hole 11a, and the fourth surface 114 is disposed toward the first glue groove 14. Specifically, the fourth surface 114 may be located at the outer periphery of the first glue groove 14, so that the glue overflowing from the first glue groove 14 may be effectively prevented from overflowing into the first mounting hole 11a, and meanwhile, since the fourth surface 114 is located at the outer periphery of the first glue groove 14, when the elastic member is bonded to the carrier 10 through the glue, the glue overflowing from the first glue groove 14 may extend along other positions of the body 11 of the carrier 10 due to the blocking of the fourth surface 114, so that the bonding area between the elastic member and the carrier 10 may be increased, and the bonding strength between the elastic member and the carrier 10 may be improved while the overflow risk is reduced.

In addition, since the third surface 113 is flush with the inner wall surface of the first mounting hole 11a, the problem that the third surface 113 protrudes out of the inner wall surface of the first mounting hole 11a to affect the mounting of the lens assembly in the first mounting hole 11a can be avoided.

In some embodiments, the first surface 12 is further provided with second glue grooves 120, the second bumps 11c, the second glue grooves 120 and the first bumps 11b are arranged at intervals along a surrounding direction of a center of the first mounting hole 11a, and the second glue grooves 120 are arranged adjacent to the second bumps 11 c. Specifically, the second glue groove 120 may be disposed at one end of the second bump 11c along the length direction X thereof, and the second glue groove 120 may be disposed close to the outer peripheral surface 11e of the body 11 of the carrier 10, so that the second glue groove 120 may be used for glue supplement to increase the bonding area between the elastic component and the carrier 10, and improve the bonding reliability between the elastic component and the carrier 10, and further, since the second glue groove 120 is disposed close to the outer peripheral surface 11e of the body 11 of the carrier 10, so that the second glue groove 120 is far away from the first mounting hole 11a, the possibility that glue overflows to the first mounting hole 11a when glue is dispensed in the second glue groove 120 may be reduced, and the overflow risk may be reduced.

Further, the number of the second glue grooves 120 can be adjusted according to the actual condition of the bonding, for example, the number of the second glue grooves 120 can be the same as the number of the first glue grooves 14, or the number of the second glue grooves 120 can also be different from the number of the first glue grooves 14. For example, the number of the first glue grooves 14 and the second glue grooves 120 may be four, or the number of the first glue grooves 14 may be four, the number of the second glue grooves 120 may be two, and the like.

As shown in fig. 4 and 5, in some embodiments, a containing groove 15 may be formed on the outer circumferential surface 11e of the body 11 of the carrier 10, and the containing groove 15 may be used to contain at least a portion of the magnetic component, so as to facilitate positioning and fixing of the magnetic component on the outer circumference of the carrier 10.

In addition, a winding post 16 may be further disposed on the outer circumferential surface 11e of the body 11, the winding post 16 is spaced apart from the accommodating groove 15, the winding post 16 is used for winding the coil, and in this case, the accommodating groove 15 may also be used for winding the coil.

In the carrier 10 disclosed in the first aspect of the embodiment of the present application, the first bump 11b and the second bump 11c spaced from the first bump 11b are disposed on the body 11 of the carrier 10, and the position of the elastic component is limited by the limiting space 11d formed between the second bump 11c and the first bump 11b, so that the displacement of the elastic component when the elastic component is connected to the carrier 10 can be avoided, and the accuracy of the connection position of the elastic component to the carrier 10 is improved.

Referring to fig. 7 to 8, a second aspect of the embodiment of the present application further discloses a driving device 20, where the driving device 20 is applied to a camera module, and the camera module includes a lens assembly. The driving device 20 comprises a base 21, a housing 22, a carrier 10, a power assembly 23 and an elastic member 24. The housing 22 can cover the periphery of the base 21 and enclose with the base 21 to form an accommodating cavity 220, the housing 22 is further provided with a second mounting hole 221 communicated with the accommodating cavity 220, and the second mounting hole 221 is used for extending the lens assembly, so that signal acquisition of the lens assembly is realized. The carrier 10 may be the carrier 10 as described in the first aspect, the carrier 10 is disposed on the base 21 and located in the accommodating cavity 220, the first mounting hole 11a is communicated with the second mounting hole 221, and when the lens assembly is mounted in the first mounting hole 11a, the lens assembly may extend from the first mounting hole 11a to the second mounting hole 221 due to the communication between the first mounting hole 11a and the second mounting hole 221, and then extend through the second mounting hole 221, so as to achieve signal acquisition. The power assembly 23 is located in the accommodating cavity 220 and disposed at the periphery of the carrier 10, and the power assembly 23 is used for driving the carrier 10 to move. The elastic member 24 is connected to the carrier 10 and is located in the spacing space 11d formed between the first projection 11b and the second projection 11 c.

By connecting the elastic member 24 to the carrier 10 and locating in the spacing space 11d formed between the first bump 11b and the second bump 11c, the elastic member 24 can be spacing-limited on the carrier 10 by using the spacing function of the spacing space 11d, so that the elastic member 24 can be positioned and spacing, the elastic member 24 is prevented from being displaced when the elastic member 24 is connected (bonded) with the carrier 10, and the accuracy of the bonding position when the elastic member 24 is bonded to the carrier 10 is effectively improved.

It is understood that the driving device 20 can be, but not limited to, an AF (Auto Focus) driving motor, an OIS (Optical image stabilization) motor or other motors. The resilient member 24 may be used to provide a resilient restoring force to return the carrier 10 to its original position after movement relative to the base 21.

In some embodiments, the base 21 may be substantially square block-shaped, cylindrical block-shaped, or other irregular block-shaped. For example, the base 21 may be a square block, and correspondingly, the housing 22 may be a square shell, and the housing 22 may be fixed together by at least one of bonding, welding, riveting, or clipping when covering the base 21. It is understood that the shapes of the base 21 and the housing 22 can be adjusted according to the actual situation, and for example, the shapes can be cylindrical at the same time.

In some embodiments, the power assembly 23 is disposed on the outer peripheral surface 11e of the body 11 of the carrier 10 for driving the carrier 10 to move the lens assembly to achieve auto-focusing. Specifically, the power assembly 23 may include a coil 230 and a plurality of magnetic members 231, wherein a start end and a tail end of the coil 230 may be wound on the winding post 16 on the outer circumferential surface 11e of the body 11, and the whole coil 230 may be wound on the outer circumferential surface 11e of the body 11, so as to connect the coil 230 and the body 11. A plurality of magnetic members 231 may be disposed at intervals on the outer circumferential surface 11e of the body 11 and adjacent to the coil 230, so that when the coil 230 is energized, the magnetic members 231 can generate a magnetic field to drive the carrier 10 to move. By adopting the way that the power assembly 23 comprises the coil 230 and the magnetic component 231, the coil 230 can be electrified to generate a secondary convention with the magnetic component 231 so as to drive the carrier 10 to move, and the driving way is simple and reliable.

Alternatively, the magnetic members 231 may be magnets, which may be in the shape of a long block or a triangular block, and may be four magnets, which are respectively disposed corresponding to the four outer circumferential surfaces 11e of the body 11 of the carrier 10, for example, the four magnets may be fixed to the outer circumferential surface 11e of the carrier 10 by bonding or snapping, so that the four magnets always remain on the outer circumference of the carrier 10.

As shown in fig. 7, it is known from the foregoing first aspect that the elastic member 24 may be used to be connected between the carrier 10 and the housing 22, and/or that the elastic member 24 may be used to be connected between the carrier 10 and the base 21. For example, the elastic member 24 may be connected between the carrier 10 and the housing 22, or the elastic member 24 may be connected between the carrier 10 and the base 21, or the elastic member 24 may be connected between the carrier 10 and the housing 22, and between the carrier 10 and the base 21. As shown in fig. 7, fig. 7 shows a scheme in which the elastic member 24 is connected between the carrier 10 and the housing 22, and between the carrier 10 and the base 21. The elastic member 24 connected between the carrier 10 and the case 22 is an upper elastic member 24a, and the elastic member 24 connected between the carrier 10 and the base 21 is a lower elastic member 24 b. The upper elastic member 24a is connected between the carrier 10 and the housing 22 for providing an elastic force to restore the carrier 10 to the original position after the carrier 10 moves relative to the housing 22. The lower elastic member 24b is connected between the carrier 10 and the base 21 for providing an elastic force to restore the carrier 10 to the original position after the carrier 10 moves relative to the base 21.

The present embodiment will be described by taking as an example the upper elastic member 24a provided between the carrier 10 and the housing 22.

Referring to fig. 9 to 11, in some embodiments, the upper elastic member 24a may be a metal sheet, that is, the upper elastic member 24a may be an elastic sheet. The upper elastic member 24a may include an inner ring portion 240, an outer ring portion 241 and a wrist portion 242, the inner ring portion 240 may be adhered to the body 11 of the carrier 10, and the inner ring portion 240 is located in a spacing space 11d formed between the first protrusion 11b and the second protrusion 11 c. An outer ring portion 241 is provided at an outer periphery of the inner ring portion 240 and spaced apart from the inner ring portion 240, and the outer ring portion 241 is adapted to be coupled to the housing 22, and the wrist portion 242 is coupled between the inner ring portion 240 and the outer ring portion 241. The wrist 242 is operable to deform when subjected to a force to provide a force to return the carrier 10 to its original position (i.e., its original position prior to the absence of movement).

It will be appreciated that the wrist 242 may be implemented as a spring wire, for example, and the wrist 242 may have at least one bend to allow sufficient amount of deformation to follow the movement of the carrier 10 as the carrier 10 moves. The outer ring portion 241 is adhesively attached to the housing 22 when attached to the housing 22.

It should be noted that when the outer ring portion 241 is connected to the housing 22 and the inner ring portion 240 is connected to the body 11, it should be noted that the wrist portion 242 is prevented from being bonded to the body 11 or the housing 22 as much as possible, so as to prevent the wrist portion 242 from providing deformation force to the body 11.

The inner ring part 240 of the upper elastic component 24a is limited by the limit space 11d formed between the first lug 11b and the second lug 11c, so that the inner ring part 240 of the elastic component 24 can be bonded with the body 11 of the carrier 10, and the bonding reliability is improved.

Alternatively, the inner ring portion 240 may be a continuous ring structure, and an inner ring of the inner ring portion 240 may be disposed corresponding to the first mounting hole 11a of the body 11 to realize a clearance for the lens assembly carried in the first mounting hole 11 a. Alternatively, the inner ring portion 240 may include a plurality of arc-shaped segments, and two adjacent arc-shaped segments may be connected by a sheet member, so that the inner ring portion 240 may be disposed substantially around the outer circumference of the first mounting hole 11a of the carrier 10.

Taking the example where the inner ring portion 240 comprises a plurality of arc segments, the inner ring portion 240 may be further provided with an extension 243, and the extension 243 may be located between the inner ring portion 240 and the outer ring portion 241. Specifically, as shown in fig. 9, the inner ring portion 240 may include four arc segments, and the extension portions 243 extend outwardly from the facing ends of two adjacent arc segments, so that the extension portions 243 may connect the two adjacent arc segments together, thereby forming the inner ring portion 240 into a substantially continuous ring shape. It is understood that the inner ring portion 240 may include two, three, five, six or more arc-shaped segments, as long as the inner ring portion 240 can surround to form a ring shape, and this embodiment is not limited in particular.

The inner ring part 240 is a plurality of arc-shaped segments, and two adjacent arc-shaped segments are connected by the extension part 243, so that the whole width of the inner ring part 240 can be made smaller, and the width of the extension part 243 can be made larger, so that the whole width of the upper elastic part 24a is smaller, and the whole structure of the driving device 20 is more compact.

Further, as can be seen from the foregoing, the inner ring portion 240 includes four arc segments, and when actually disposed, the extension portions 243 may be disposed approximately corresponding to four corners of the body 11 of the carrier 10, so that the extension portions 243 may also be connected to the body 11 of the carrier 10, so that not only the inner ring portion 240 may be connected to the body 11, but also the extension portions 243 may be connected to the body 11, which effectively increases the bonding area between the upper elastic component 24a and the body 11.

In some embodiments, the extension portion 243 may be provided with a first clearance groove 243a corresponding to the first bump 11b, the extension portion 243 may be provided with a second clearance groove 243b corresponding to the second bump 11c, the first clearance groove 243a may be used for clearance of the first bump 11b, and the second clearance groove 243b may be used for clearance of the second bump 11 c. By providing the extension portion 243 on the inner ring portion 240 and providing the first clearance groove 243a and the second clearance groove 243b on the extension portion 243, the first clearance groove 243a and the second clearance groove 243b can be utilized to realize clearance limitation on the first bump 11b and the second bump 11c, and effectively realize a limitation on the upper elastic member 24 a.

It can be understood that the shapes and sizes of the first clearance groove 243a and the second clearance groove 243b can be substantially matched with the first bump 11b and the second bump 11c, so that the spacing between the upper elastic component 24a and the body 11 can be conveniently realized, and the spacing precision can be improved.

In some embodiments, a dispensing hole 244 is formed through the upper elastic member 24a, and the dispensing hole 244 can be used for dispensing to connect the upper elastic member 24a and the body 11. Specifically, the dispensing hole 244 may be disposed on the extension 243, so as to avoid a problem that the dispensing hole 244 is disposed on the inner ring portion 240 to affect the overall structural strength of the inner ring portion 240.

Considering that the first glue groove 14 is formed on the body 11, and the first protrusion 11b is disposed on a side of the first glue groove 14 facing the first mounting hole 11a, for facilitating glue dispensing and increasing the bonding area between the upper elastic component 24a and the body 11, the glue dispensing hole 244 on the extension portion 243 may be at least partially offset from the first glue groove 14 on the body 11. Thus, when the upper elastic member 24a is connected to the body 11, glue can overflow to the body 11 through the dispensing hole 244 by dispensing in the dispensing hole 244, and if the dispensing hole 244 is partially communicated with the first glue groove 14, glue can overflow to the first glue groove 14 from the dispensing hole 244, so that more glue can be provided and the bonding strength can be increased. If the dispensing hole 244 is completely offset from the first glue groove 14, dispensing can be performed in the dispensing hole 244 and the first glue groove 14, respectively, and the bonding area between the upper elastic member 24a and the body 11 can be increased.

The positional relationship between the dispensing holes 244 and the first glue grooves 14, and the number of the dispensing holes 244 and the first glue grooves 14 will be exemplified below. It should be noted that, the following description mainly takes the glue dispensing hole 244 on one extending portion 243 and the first glue groove 14 at the corresponding position of the one extending portion 243 on the body 11 as an example.

For example, the glue dispensing hole 244 provided in one of the extending portions 243 may be one or more, and the first glue groove 14 provided in the body 11 at a position corresponding to the one extending portion 243 may also be one or more. The dispensing hole 244 and the first glue groove 14 can be arranged in the following manners:

first, the number of the dispensing holes 244 and the first glue grooves 14 is described, and when there is only one dispensing hole 244 and one first glue groove 14, the following arrangement is adopted:

in an alternative embodiment, as shown in fig. 11, a portion of the dispensing hole 244 is staggered from the first glue groove 14, and another portion of the dispensing hole 244 is communicated with the first glue groove 14, so that when the upper elastic component 24a needs to be bonded to the body 11, glue can be dispensed into the dispensing hole 244, and since the portion of the first glue groove 14 and the dispensing hole 244 are staggered, the glue entering from the dispensing hole 244 can flow into the first glue groove 14 from the portion of the dispensing hole 244 communicated with the first glue groove 14 until the first glue groove 14 is filled. Since the dispensing hole 244 and the first glue groove 14 are partially staggered, the glue dispensed from the dispensing hole 244 can form a glue column at the staggered portion of the dispensing hole 244 and the first glue groove 14. That is, in the present embodiment, the glue columns can be formed at the positions of the glue dispensing holes 244 deviated from the first glue groove 14, the positions of the glue dispensing holes 244 communicating with the first glue groove 14, and the positions of the first glue groove 14 deviated from the glue dispensing holes 244, so that the areas for glue storage and dispensing are increased, the bonding area between the upper elastic member 24a and the body 11 is increased, and the bonding stability between the upper elastic member 24a and the body 11 can be improved.

In another alternative embodiment, as shown in fig. 12, the dispensing hole 244 and the first glue groove 14 are completely staggered, that is, the dispensing hole 244 is not communicated with the first glue groove 14, and then the first glue groove 14 and the dispensing hole 244 can be used for dispensing and accommodating glue, respectively, so that the glue accommodating areas of the body 11 and the upper elastic member 24a can be increased.

When the dispensing holes 244 and the first glue grooves 14 are arranged in a plurality of numbers, and the dispensing holes 244 are arranged at intervals, and the first glue grooves 14 are arranged at intervals, each dispensing hole 244 may be partially staggered with each first glue groove 14, or part of the dispensing holes 244 may be partially staggered with part of the first glue grooves 14, and the other dispensing holes 244 may be completely communicated with the other first glue grooves 14 or completely staggered.

Taking the first glue groove 14 and the glue dispensing hole 244 as an example, two glue dispensing holes 244 may be provided on one extension portion 243, and two first glue grooves 14 may be provided at a position of the body 11 corresponding to the one extension portion 243, so that in the first example, the two first glue grooves 14 may be respectively partially staggered from the two glue dispensing holes 244, as shown in fig. 13.

In the second example, one of the first glue grooves 14 may be partially offset from one of the glue dispensing holes 244, and the other first glue groove 14 may be completely communicated with the other glue dispensing hole 244 (as shown in fig. 14).

In a third example, one of the first glue grooves 14 may be partially offset from one of the glue dispensing holes 244, and the other first glue groove 14 may be completely offset from the other glue dispensing hole 244 (as shown in fig. 11).

In the fourth example, one dispensing hole 244 is simultaneously partially connected to two first glue grooves 14, and a part of the dispensing hole 244 is not connected to the two first glue grooves 14, as shown in fig. 15, for example.

In the fifth example, two dispensing holes 244 may be simultaneously partially connected to one first glue groove 14, while another portion of the two dispensing holes 244 is not connected to the one first glue groove 14, as shown in fig. 16.

It should be noted that, when there are a plurality of first glue grooves 14 on the body 11 and there is a situation where the first glue grooves 14 are completely staggered from the glue dispensing holes 244 on the extension portions 243, the first glue grooves 14 completely staggered from the glue dispensing holes 244 can be used for glue dispensing alone.

It should be understood that the number and the arrangement manner of the first glue groove 14 and the glue dispensing holes 244 are only examples, that is, as long as at least one glue dispensing hole 244 is disposed on the extension portion 243 and can be partially staggered from the first glue groove 14 on the body 11, the number of the first glue groove 14 and the glue dispensing hole 244 is not particularly limited in this embodiment.

In addition, the dispensing holes 244 may be regular holes such as long holes, round holes, square holes, etc., or other irregular holes. Correspondingly, the first glue groove 14 may be a long groove, a circular groove, a square groove, or the like, but may also be other grooves of different shapes. For example, as shown in fig. 14, fig. 14 shows a manner in which the first glue groove 14 is a square groove and the dispensing hole 244 is an elliptical hole, and fig. 15 shows a manner in which the first glue groove 14 is an elliptical groove and the dispensing hole 244 is an elliptical hole.

Alternatively, considering that since the upper elastic member 24a is an elastic sheet, if the area of the dispensing hole 244 provided thereon is large, the structural strength of the upper elastic member 24a may be affected, and therefore, the area ratio of the first glue groove 14 to the dispensing hole 244 is 2:1-8:1, that is, the area of the first glue groove 14 is larger than the area of the dispensing hole 244, the area of the glue can be transferred to the body 11 as much as possible, and the structural strength of the upper elastic member 24a can be ensured while ensuring the area of the glue. Illustratively, the area ratio of the first glue groove 14 to the glue dispensing hole 244 may be 2:1, 3:1, 4:1, 5:1, 6:1, 7:1, 8:1, etc. For example, if the dispensing hole 244 has an area of 0.1mm to 1mm, the first glue groove 14 may have an area of 0.2mm to 8 mm. It should be understood that the areas of the first glue groove 14 and the glue dispensing hole 244 are only examples and do not limit the scope of the present embodiment.

In some embodiments, in order to increase the bonding area of the upper elastic member 24a and the body 11 as much as possible, when the dispensing hole 244 is partially communicated with the first glue groove 14, the area of the portion of the dispensing hole 244 communicated with the first glue groove 14 may be smaller than or equal to the area of the portion of the dispensing hole 244 staggered from the first glue groove 14, so that glue may flow from the dispensing hole 244 into the first glue groove 14 when dispensing from the dispensing hole 244, thereby forming a glue column at a position of the dispensing hole 244 not communicated with the first glue groove 14, a position of the dispensing hole 244 communicated with the dispensing hole 244, and a position of the first glue groove 14 not communicated with the dispensing hole 244, thereby greatly increasing the bonding area of the upper elastic member 24a and the body 11, and making the bonding of the upper elastic member 24a and the body 11 more secure.

Referring to fig. 9 and 10 again, in view of the foregoing, a second glue groove 120 is further disposed on the first surface 12 of the main body 11, and in order to facilitate glue filling, a third glue groove 245 may be disposed at a position of the upper elastic component 24a corresponding to the second glue groove 120, and the third glue groove 245 may be communicated with the second glue groove 120. Specifically, the third glue groove 245 may be disposed on the extension portion 243, and the third glue groove 245 may be disposed adjacent to the second clearance groove 243b, so that when the upper elastic member 24a is connected to the carrier 10, glue may be dispensed through the third glue groove 245, and glue may overflow into the second glue groove 120 through the third glue groove 245, thereby increasing the bonding area between the upper elastic member 24a and the body 11.

In addition, by providing the third glue groove 245 on the extension portion 243, the third glue groove 245 is communicated with the second glue groove 120, so that the third glue groove 245 can be used as a glue supplementing groove, and when the upper elastic component 24a is bonded with the body 11 poorly or needs glue supplementing, glue can be dispensed through the third glue groove 245, and glue supplementing is further achieved.

In the driving device 20 disclosed in the second aspect of the embodiment of the present application, the dispensing hole 244 is disposed on the extending portion 243 of the upper elastic member 24a, and at least a portion of the dispensing hole 244 is disposed in a staggered manner with respect to the first glue groove 14, so that when the upper elastic member 24 is required to be connected to the body 11, glue can be dispensed to the dispensing hole 244, so that the glue can overflow from the dispensing hole 244 to the first glue groove 14, the dispensing and glue containing areas of the upper elastic member 24a and the body 11 are effectively increased, the bonding area of the upper elastic member 24a and the body 11 is increased, and further, the bonding stability of the upper elastic member 24a and the body 11 can be improved.

In addition, because the first glue groove 14 is used for receiving glue, and the first bump 11b is disposed on a side of the first glue groove 14 facing the first mounting hole 11a, the first bump 11b can not only cooperate with the second bump 11c to form a limiting space 11d for limiting the upper elastic component 24a, but also serve as a retaining wall to prevent excess glue in the first glue groove 14 from overflowing into the first mounting hole 11a, and meanwhile, due to the blocking effect of the first bump 11b, excess glue in the first glue groove 14 can overflow along other positions (not the position of the first mounting hole 11 a) of the body 11, so that not only is the bonding area between the upper elastic component 24a and the body 11 increased, but also the overflow risk can be reduced, and the lens assembly located in the first mounting hole 11a is prevented from being polluted.

In a third aspect, referring to fig. 17, an embodiment of the present application further discloses a camera module 30, where the camera module 30 includes a lens assembly 31, an image sensor (not shown), and the driving device 20 as described in the second aspect, where the lens assembly 31 is carried on the first mounting hole 11a of the carrier 10 of the driving device 20, and a lens end of the lens assembly 31 extends out through the second mounting hole 221 on the housing 22 to realize framing, so that the driving device 20 can be drivingly connected with the lens assembly 31 to drive the lens assembly 31 to move to realize auto-focusing. As shown in fig. 17, the direction of the arrow in fig. 16 is the optical axis direction of the lens assembly 31. Specifically, the lens assembly 31 is mounted in the first mounting hole 11a of the carrier 10 of the driving device 20 and partially protrudes from the second mounting hole 221 of the housing 22. When the coil 230 of the driving device 20 is powered on, the carrier 10 may drive the lens assembly 31 to move along the optical axis of the lens assembly 31, so as to drive the lens assembly 31 to achieve auto-focusing. The image sensor is arranged at one end of the base 21, which is far away from the carrier 10, and is used for receiving the optical signal collected by the lens assembly 31 and imaging.

It can be understood that the image capturing module 30 in the present embodiment has the driving device 20 described above, and therefore the image capturing module 30 in the present embodiment has all the technical effects of the driving device 20 described above, and since the technical effects of the driving device 20 have been fully described above, the detailed description thereof is omitted.

In a fourth aspect, as shown in fig. 18, an embodiment of the present application further discloses an electronic device 40, where the electronic device 40 may be, for example, a mobile phone, a tablet computer, a telephone watch, a security camera, a vehicle-mounted camera, and other devices capable of acquiring image information.
