Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

First, a brief description will be given of an image capturing module 100 according to an embodiment of the second aspect of the present utility model with reference to fig. 1 to 4, the image capturing module 100 including a motor 10 for the image capturing module 100 according to an embodiment of the first aspect of the present utility model, the motor 10 being disposed in the image capturing module 100, the image capturing module 100 implementing an auto focus function by means of the motor 10.

A motor 10 for an image pickup module 100 according to an embodiment of the first aspect of the present utility model is described below with reference to fig. 1 to 4.

As shown in fig. 2 and 3, a motor 10 for an image pickup module 100 according to an embodiment of the first aspect of the present utility model includes: the outer housing 11, the carrier 14, the drive assembly 12 and the elastic member 13. The carrier 14 is movably arranged in the outer shell 11; the driving assembly 12 is arranged in the outer shell 11 and is used for driving the carrier 14 to move relative to the outer shell 11; the elastic member 13 is sealingly connected between the outer shells 11 of the carrier 14.

In this embodiment, by providing the sealed elastic member 13 between the outer side surface of the carrier 14 and the inner side surface of the outer casing 11, it is possible to effectively prevent impurities such as dust and water drops outside the camera module 100 from entering the camera module 100 from between the outer casing 11 of the camera module 100 and the carrier 14 provided in the outer casing 11, so that the working environment of each component in the camera module 100 is better maintained, and the camera module 100 can normally and stably acquire images or video information in complex and changeable working environments.

Further, the elastic member 13 is provided with the deformation portion 131, and the deformation portion 131 extends along a curve and/or a folding line between the outer case 11 and the carrier 14, that is, the deformation portion 131 may extend along a curve, may extend along a folding line, or may extend along a curve and a folding line in a direction from an end of the elastic member 13 connected to the outer case 11 toward an end of the carrier 14. For example, the elastic member 13 is formed in a ring shape, the radially inner end of the elastic member 13 is connected to the carrier 14, the radially outer end of the elastic member 13 is connected to the outer shell 11, the deformation portion 131 is bent or bent and extended in the radial direction of the elastic member 13, and the total length of both ends of the elastic member 13 is greater than the linear length of both ends of the elastic member 13, so that when the carrier 14 moves in the optical axis direction, the carrier 14 drives one end of the elastic member 13 connected to the carrier 14 to move, and as the moving distance of the carrier 14 increases, the linear distance between one end of the elastic member 13 connected to the outer shell 11 and the other end of the elastic member 13 connected to the carrier 14 also increases in the radial direction of the elastic member 13, at this time, the elastic member 13 deforms, and at the same time, a part of the deformation portion 131 is stretched and stretched, so that the linear length of both ends of the elastic member 13 increases, thereby enabling the elastic member 13 to move in a larger stroke to be satisfied by the carrier 14 and always playing a role of sealing between the carrier 14 and the outer shell 11.

Meanwhile, since the elastic member 13 has the deformation portion 131 extending along the curve and/or the fold line between the outer housing 11 and the carrier 14, that is, the elastic member 13 has an uneven surface structure, when dust, rainwater, splashes and the like in the external environment fall onto the elastic member 13, the elastic member 13 can play a certain role in accommodating the impurities, and in the process that the motor 10 works, the carrier 14 moves along the optical axis direction, dust, water drops and the like accommodated on the elastic member 13 are not easy to move everywhere and enter the lens 20, thereby effectively improving the normal operation condition of the camera module 100 in the working process of the motor 10 and enabling the use state of the camera module 100 to be more stable.

According to the motor 10 for the camera module 100 of the embodiment of the utility model, the elastic piece 13 is arranged, and the elastic piece 13 is connected between the outer side surface of the carrier 14 and the inner side surface of the outer shell 11 in a sealing way, the elastic piece 13 is provided with the deformation part 131, the deformation part 131 extends along a curve and/or a fold line between the outer shell 11 and the carrier 14, the elastic piece 13 can well meet the sealing and dust-proof effects of the camera module 100 when the carrier 14 moves in a large stroke way, the lens 20 can move more stably, and the dust and the like on the elastic piece 13 can be prevented from moving everywhere when the carrier 14 moves, so that the normal operation condition of the camera module 100 in the working process of the motor 10 is effectively improved, and the use state of the camera module 100 is more stable.

In some embodiments of the present utility model, as shown in fig. 2 to 4, the deformation 131 extends along a line protruding and/or recessed in the optical axis direction in the direction from the carrier 14 to the outer case 11. That is, the deformation portion 131 may extend along a line of protrusion in the optical axis direction, the deformation portion 131 may extend along a line of depression in the optical axis direction, and the deformation portion 131 may extend along a line of protrusion and depression in the optical axis direction. Therefore, by setting the deformation portion 131 to be in a wavy form, the elastic member 13 can have a larger deformation capability along the optical axis direction, so that the movement of the carrier 14 along a larger stroke along the optical axis direction can be matched better, meanwhile, the elastic member 13 can have a certain accommodating effect on sundries such as dust, liquid drops and the like falling on the elastic member 13, the situation that the dust and the like play everywhere when the elastic member 13 is deformed is prevented, and the working condition of the camera module 100 is kept in a good state. Preferably, the relief form and the relief degree of the deformation portion 131 of the elastic member 13 can be reasonably set according to the actual sealing requirement and the stroke of the carrier 14, so that the sealing effect of the elastic member 13 is optimized.

In some embodiments of the present utility model, as shown in fig. 2 to 4, the deformation 131 may extend along a wavy line undulating in the optical axis direction. The deformation portion 131 takes the form of a wavy line, so that the total length of the elastic member 13 from one end to the other end of the elastic member 13 in the radial direction can be much longer than the straight length from one end to the other end of the elastic member 13, that is, when the elastic member 13 is in the initial state (the unstretched state as shown in fig. 3), the elastic member 13 has a larger surface area under the condition that the overall length dimension is unchanged, so that the elastic member 13 has a larger stretching deformation capability along the optical axis direction, and therefore, when the carrier 14 moves along the optical axis direction, the end, connected with the carrier 14, of the elastic member 13 can be stretched by a larger length, thereby expanding the adaptation range of the elastic member 13.

In one embodiment of the present utility model, as shown in fig. 2 to 4, the deformation portion 131 may have a plurality of peaks, the plurality of peaks having different heights in the optical axis direction. That is, the deformation portion 131 has two or more peaks with different heights protruding in the optical axis direction. The deformation part 131 forms a continuous wave structure, and the bending part is mild, so that when the elastic piece 13 stretches along the optical axis direction, stress concentration at the bottom of a wave crest after the deformation part 131 stretches is reduced, and the service life of the elastic piece 13 is prolonged; when the elastic member 13 is stretched, the portion of the peak with a lower protrusion height in the optical axis direction is stretched more easily, and can be straightened in a shorter stroke of the carrier 14, while the portion with a higher protrusion height is not stretched easily, and can be straightened completely after a longer stroke of the carrier 14 is required.

Therefore, by setting the peaks with at least two different heights, on one hand, the positions of the deformation parts 131 on the elastic piece 13 for stretching deformation are orderly, so that the stretching deformation process of the elastic piece 13 is more stable, and on the other hand, when the length of the elastic piece 13 which needs stretching when the carrier 14 moves is met, the parts of the deformation parts 131 in the elastic piece 13 which need stretching deformation can be reduced as much as possible, so that the integral structure of the elastic piece 13 is more stable, and the support and the deformation buffering of the elastic piece on the carrier 14 and the lens 20 are more stable when the carrier 14 moves to focus the lens 20.

In one embodiment of the present utility model, as shown with reference to fig. 2 to 4, the deformation portion 131 may include a plurality of deformation layers, which are stacked in the optical axis direction. Therefore, in the long-term use process, when the outermost layer of the deformation portion 131 along the optical axis direction is aged, broken or worn, the deformation portion 131 still has a multi-layer complete and good structure, so that the deformation portion 131 can still maintain a good use state, the service life of the elastic member 13 is prolonged, and the working stability of the elastic member 13 is better. For example, the deformation layer in the deformation portion 131 may be provided with two, three or more layers, and the specific layer may be set reasonably according to actual needs.

In some embodiments of the present utility model, as shown in fig. 2 to 4, the elastic member 13 may further include a first connection portion 132 and a second connection portion 133, the first connection portion 132 and the second connection portion 133 being connected to both ends of the deformation portion 131, respectively, the first connection portion 132 being connected to the carrier 14, and the second connection portion 133 being connected to the outer case 11. Specifically, the first connecting portion 132 and the second connecting portion 133 do not have deformability, whereby the elastic member 13 is connected and fixed with the carrier 14 and the outer case 11 by providing the first connecting portion 132 and the second connecting portion 133.

In some embodiments of the present utility model, as shown in fig. 2 to 4, at least one side surface of the elastic member 13 along the optical axis direction is provided with the ribs 134, that is, the ribs 134 may be provided on one side surface of the elastic member 13 along the optical axis direction, or may be provided on both side surfaces of the elastic member 13 along the optical axis direction. The bead 134 extends in a ring shape around the optical axis, the bead 134 being disposed between the deformation portion 131 and the first connection portion 132, and/or the bead 134 being disposed between the deformation portion 131 and the second connection portion 133. That is, the ribs 134 may be disposed between the deformation portion 131 and the first connection portion 132, the ribs 134 may be disposed between the deformation portion 131 and the second connection portion 133, and the ribs 134 may be disposed between the deformation portion 131 and the first connection portion 132 and between the deformation portion 131 and the second connection portion 133, so that the ribs 134 may limit the deformation portion 131 and the rest of the elastic member 13, so that the elastic member 13 is fixed and the working process is more stable and reliable. For example, as shown in fig. 4, an annular bead 134 is provided on one side surface of the elastic member 13 in the optical axis direction.

In one embodiment of the present utility model, as shown in fig. 2, the bead 134 may include at least two beads 134, and at least two beads 134 are disposed at both sides of the deformation 131, respectively. That is, two or more ribs 134 may be provided on both sides of the deformation portion 131, and the specific number may be set according to actual needs. In this way, the deformation portion 131 and the rest of the elastic member 13 can be limited, so that the overall structure of the elastic member 13 is more stable in the initial state.

In some embodiments of the present utility model, as shown in fig. 2 to 4, the thickness of the deformation portion 131 in the optical axis direction may be smaller than the thickness of the elastic member 13 at the rest position. In this way, the deformation part 131 is easier to be subjected to tensile deformation, the tensile deformation capacity of the elastic piece 13 is improved, and meanwhile, the thickness of the deformation part 131 is smaller than that of other positions, so that the elastic piece 13 is easier to deform at the deformation part 131 when being subjected to force, and the deformation and non-deformation areas of the elastic piece 13 are clearer.

In some embodiments of the present utility model, referring to fig. 2-4, the elastic member 13 may be a plastic member, a silicone member, or a liquid crystal polymer member. Therefore, the elastic piece 13 is manufactured by using the plastic piece, the silica gel piece or the liquid crystal polymer piece, so that the weight of the elastic piece 13 is lighter, the resistance of the carrier 14 during movement is reduced, the focusing of the lens 20 is easier, and the elastic piece 13 can stretch with larger stroke in order to meet the movement of the carrier 14 with larger stroke in the movement process of the carrier 14 due to stronger material deformation capability, so that the adaptation range of the elastic piece 13 is enlarged. For example, the elastic member 13 may be made of plastic material, silicone material, or liquid crystal polymer material.

In some embodiments of the present utility model, as shown in fig. 3, the carrier 14 may be a ring-shaped cylinder, and the elastic members 13 may include two elastic members 13 respectively located at both ends of the carrier 14 in the optical axis direction. In this way, the upper end (the upper direction in the up-down direction as shown in fig. 1) and the lower end (the lower direction in the up-down direction as shown in fig. 1) of the carrier 14 can be respectively supported by the two elastic members 13, and the movement of the carrier 14 is deformed and buffered, so that the carrier 14 is more firmly fixed, the work is more stable, and meanwhile, the double sealing is performed between the carrier 14 and the outer shell 11, so that the waterproof and dustproof effects of the camera module 100 are better. As shown in fig. 2 and 3, for example, one of the two elastic members 13 is provided between the upper side surface of the carrier 14 and the outer case 11, the other is provided between the lower side surface of the carrier 14 and the outer case 11, and the two elastic members 13 are symmetrically provided in the optical axis direction.

Therefore, the elastic piece 13 is tightly and firmly connected with the carrier 14, the sealing performance of the elastic piece 13 is better, and the elastic piece 13 and the carrier 14 are convenient to disassemble and assemble. For example, the elastic element 13 can be connected to the carrier 14 by hot riveting, by gluing, or by hot melting.
