Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electronic products, and particularly relates to a photographing device and an electronic device. BACKGROUND

[0002] With the continuous improvement of users' requirements for photographing, the zoom ratio of the photographing device is more and more diversified, and the size is also getting larger and larger, so that the lens needs more and more working moving space.

[0003] When the photographing device is not working, the lens is in a free and uncontrolled state in the cavity of the photographing device, and when the photographing device shakes, the lens is in a free swing state in the cavity, which is easy to cause the lens to hit the cavity and produce abnormal noise. The abnormal noise increases with the increase of the cavity space and the weight of the lens, and the noise perception is obvious.

[0004] At present, the following schemes are commonly used to solve the internal impact abnormal noise of the photographing device: scheme one, adding flexible buffer materials at the impact part. This scheme has a certain noise reduction effect, but the increase of the flexible part occupies the moving space of the lens, reducing the moving stroke of the lens; scheme two, using software control measures. This scheme has the problems of difficult debugging and large power consumption, affecting the endurance time of the photographing device, and only effective when the photographing device is in the powered-on state, and cannot solve the impact abnormal noise problem when the photographing device is not powered on.

[0005] Therefore, under the condition of ensuring the moving stroke of the lens, how to reduce the impact abnormal noise in the photographing device is a technical problem to be solved. SUMMARY

[0006] The purpose of the embodiments of the present application is to provide a photographing device and an electronic device, which can reduce the impact abnormal noise in the photographing device while ensuring the moving stroke of the lens.

[0007] In order to solve the above technical problems, the present application is implemented as follows:

[0008] In a first aspect, the embodiments of the present application provide a photographing device, comprising:

[0009] a frame body forming a receiving space;

[0010] a lens module arranged in the receiving space;

[0011] The frame body comprises a bottom wall, and at least one group of magnetic field generating components is arranged on the bottom wall. Each group of magnetic field generating components comprises first and second magnetic field generating components arranged opposite to each other with a first interval space. The extension direction of the first interval space is parallel to the optical axis direction of the lens module.

[0012] At least one metal piece is arranged on the lens module, one metal piece corresponds to one set of magnetic field generating components;

[0013] During reciprocating movement of the lens module relative to the frame along the optical axis, at least one metal piece reciprocates in the first interval space, and the metal piece generates a magnetic force opposite to the movement direction by cutting the non-uniform magnetic field generated by the magnetic field generating components.

[0014] In a second aspect, the embodiments of the present application provide an electronic device, including a shell and the photographing device as described in the first aspect, and the photographing device is located in the accommodation space of the shell.

[0015] In the embodiments of the present application, the photographing device includes a frame and a lens module, at least one set of magnetic field generating components is arranged on the bottom wall of the frame, the magnetic field generating components generate a non-uniform magnetic field, when the photographing device shakes, the lens module moves or rotates along the optical axis, the metal piece generates an eddy current in the interior of the metal piece by cutting the non-uniform magnetic field generated by the magnetic field generating components; the rotation of the eddy current forms a secondary magnetic field, the secondary magnetic field is opposite to the magnetic field generated by the magnetic field generating components, and the two resist each other. In this way, the moving metal piece will reduce the moving speed after being subjected to the opposite force, so as to achieve an effect similar to damping. Since the metal piece is fixedly connected with the lens module, the moving speed of the lens module can be reduced, and the impact noise generated by the lens module impacting other components can be weakened, so as to solve the problem that the loudness of the impact between the lens module and other components in the photographing device caused by shaking is too large.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0040] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.

[0041] The control method provided by the embodiments of the present application will be described in detail below with reference to the drawings and through specific embodiments and application scenarios.

[0042] Please refer to Figures 1 to 18 The embodiments of the present application provide a shooting device, comprising:

[0043] The frame 1 forms a receiving space;

[0044] The lens module 2 is arranged in the receiving space;

[0045] The frame 1 comprises a bottom wall 11, and at least one group of magnetic field generating components 4 is arranged on the bottom wall 11. Each group of magnetic field generating components 4 comprises a first magnetic field generating component 41 and a second magnetic field generating component 42 arranged oppositely with a first interval space. The extension direction of the first interval space is parallel to the optical axis direction of the lens module 2;

[0046] The lens module 2 is provided with at least one metal piece 3, and one metal piece 3 corresponds to one group of magnetic field generating components 4;

[0047] During reciprocating movement of the lens module 2 relative to the frame 1 along the optical axis, the at least one metal piece 3 reciprocates in the first interval space, and the metal piece 3 cuts through the non-uniform magnetic field generated by the magnetic field generating component 4 to generate a magnetic force opposite to the direction of movement.

[0048] It should be explained that the magnetic field generating component 4 can generate a variable non-uniform magnetic field. When the camera device shakes, the lens module 2 moves or rotates quickly along the optical axis, and the metal piece 3 cuts through the variable non-uniform magnetic field generated by the magnetic field generating component 4 to generate an eddy current in the metal piece 3. The rotation of the eddy current forms a secondary magnetic field, which is opposite to the magnetic field generated by the magnetic field generating component 4 according to Lenz's law, and the two resist each other. After being subjected to the opposite force, the moving speed of the metal piece 3 will decrease, so as to achieve a similar effect to damping. Since the metal piece 3 is fixedly connected with the lens module 2, the moving speed of the lens module 2 can be reduced, the impact noise generated by the lens module 2 impacting other components can be weakened, and thus the problem of excessive loudness caused by the lens module 2 colliding with other components due to shaking in the camera device can be solved.

[0049] It should be pointed out that the faster the magnetic field generated by the magnetic field generating component 4 changes, the larger the cross-sectional area S of the metal piece 3, the smaller the resistivity of the metal piece 3, and the larger the eddy current formed in the metal piece 3. The faster the speed of the metal piece 3 passing through the magnetic field, the larger the eddy current formed in the metal piece 3, and the faster the lens module 2 slows down.

[0050] In some optional embodiments, as shown in Figures 19 to 21 the first magnetic field generating component 41 and the second magnetic field generating component 42 are multi-pole magnets; wherein the first magnetic field generating component 41 and the second magnetic field generating component 42 respectively have alternating magnetic poles arranged along a first direction on a side close to each other, and the first direction is parallel to the optical axis direction.

[0051] The polarities of the magnetic pole regions on the opposite sides of the first interval space in the first magnetic field generating component 41 and the second magnetic field generating component 42 are opposite.

[0052] In an implementation manner, the first magnetic field generating component 41 and the second magnetic field generating component 42 respectively include a plurality of magnets arranged in an array.

[0053] In another implementation manner, the first magnetic field generating component 41 and the second magnetic field generating component 42 are respectively one-piece magnet structures.

[0054] Exemplarily, as shown in Figure 11 and Figure 12As shown, the first magnetic field generating component 41 and the second magnetic field generating component 42 respectively include two rows of eight columns of magnets arranged in an array, a total of 16 magnets, and the polarity of adjacent two magnets is opposite; the first magnetic field generating component 41 and the second magnetic field generating component 42 are located on both sides of the first spacing space, and the two magnets opposite on both sides of the first spacing space are arranged with the S pole opposite the N pole. In this way, a changing non-uniform magnetic field can be formed in the first spacing space.

[0055] As shown in FIG. 4, which shows a schematic diagram of the metal piece 3 moving out of the first spacing space. As shown in FIG. 5, Figure 11 As shown in FIG. 6, which shows a schematic diagram of the metal piece 3 moving into the first spacing space. Figure 12 、 Figure 15 and Figure 16 As shown in FIG. 7, which shows a schematic diagram of the metal piece 3 moving into the first spacing space.

[0056] It should be noted that, Figure 11 and Figure 12 are only examples, when the first magnetic field generating component 41 and the second magnetic field generating component 42 are multi-pole magnets, other magnetic pole arrangement forms can also be used. For example, the magnetic pole arrangement shown in FIG. 8 can also be used. Figures 19 to 21

[0057] As another optional embodiment, the principle of electromagnetism can also be used to make the magnetic generating component generate a changing non-uniform magnetic field. For example, the first magnetic field generating component 41 and the second magnetic field generating component 42 can respectively include a plurality of coils arranged in parallel to the optical axis direction (not shown in the figure), the first magnetic field generating component 41 and the second magnetic field generating component 42 are located on both sides of the first spacing space, and the two coils opposite in the first magnetic field generating component 41 and the second magnetic field generating component 42 generate magnetic fields in the same direction in the first spacing space, and the two coils adjacent in the first magnetic field generating component 41 and the second magnetic field generating component 42 generate magnetic fields in opposite directions in the first spacing space, so that a changing non-uniform magnetic field can be generated in the first spacing space.

[0058] In some optional embodiments, the first magnetic field generating component 41 and the second magnetic field generating component 42 also respectively include:

[0059] A beam magnetic sheet 401, one side of the beam magnetic sheet 401 is fixedly connected with the bottom wall 11; and a multi-pole magnet is arranged on the other side of the beam magnetic sheet 401.

[0060] Exemplarily, as shown in FIG. 9, which shows an exploded schematic diagram of the beam magnetic sheet 401 and the first magnetic field generating component 41 and the second magnetic field generating component 42; and as shown in FIG. 10, which shows a schematic diagram of the installation state of the beam magnetic sheet 401 and the first magnetic field generating component 41 and the second magnetic field generating component 42. Figure 5 Figure 6

[0061] ​​​Optionally, the beam magnetic sheet 401 is made of magnetic material, such as cold rolled carbon steel (SPCC) material.

[0062] Optionally, each group of magnetic field generating components 4 corresponds to two beam magnetic sheets 401, one side of the beam magnetic sheet 401 is fixed on the bottom wall 11 by the glue dispensing process, and the other side of the beam magnetic sheet 401 is fixedly connected with the multi-pole magnet by the glue dispensing process. In this way, the side magnetic field strength of the magnetic field generating component 4 can be enhanced by the beam magnetic sheet 401.

[0063] In some optional embodiments, the photographing device further comprises:

[0064] A guide mechanism is arranged between the lens module 2 and the bottom wall 11.

[0065] A driving mechanism is connected with the lens module 2.

[0066] Under the cooperation of the driving mechanism and the guide mechanism, the lens module 2 reciprocates along the optical axis direction relative to the frame 1, and the lens module 2 drives the at least one metal piece 3 to make a cutting magnetic induction line motion in the first interval space.

[0067] Optionally, the driving mechanism comprises a magnet and a coil (not shown in the figure), such as Figure 4 The magnet comprises N and S poles and is arranged on the lens module 2. Under the driving action of the coil and the magnet and the guiding action of the guide mechanism, the lens module 2 can reciprocate along the optical axis direction to realize the focusing function.

[0068] In some optional embodiments, the guide mechanism comprises:

[0069] At least two first sliding grooves 111 are arranged on the bottom wall 11, and the extension direction of the first sliding groove 111 is parallel to the optical axis direction.

[0070] At least two second sliding grooves 22 are arranged on the lens module 2, and the extension direction of the second sliding groove 22 is parallel to the optical axis direction. The second sliding groove 22 corresponds to the first sliding groove 111 one by one, and the ball 6 is clamped between the first sliding groove 111 and the second sliding groove 22.

[0071] Each group of magnetic field generating components 4 is arranged on one side of the first sliding groove 111, and the extension direction of the first interval space is parallel to or coincides with the extension direction of the first sliding groove 111 and the second sliding groove 22.

[0072] For example, as shown in the figure, Figure 4 Three second sliding grooves 22 are arranged on the lens module 2. Correspondingly, three first sliding grooves 111 are arranged on the two sides of the bottom wall 11, as shown in the figure, Figure 8 and Figure 9As shown, the extending direction of the first sliding groove 111 is parallel to the optical axis direction. The first sliding groove 111 corresponds to the second sliding groove 22 one by one, and one ball 6 is arranged between each group of the first sliding groove 111 and the second sliding groove 22. In this way, the first sliding groove 111 and the second sliding groove 22 can play a guiding role during the movement of the lens module 2, and the ball 6 can play a role of supporting the lens module 2.

[0073] Exemplarily, Figure 9 As shown, a group of magnetic field generating components 4 is arranged on both sides of the first sliding groove 111, such as Figure 4 As shown, a metal piece 3 is arranged on both sides of the second sliding groove 22 in the lens module 2, such as Figure 10 As shown, during the movement of the lens module 2 relative to the bottom wall 11, at least one metal piece 3 moves in the first interval space.

[0074] It should be pointed out that if a plurality of first sliding grooves 111 are arranged on the bottom wall 11, a group of magnetic field generating components 4 can be arranged on one side of one first sliding groove 111, or a group of magnetic field generating components 4 can be arranged on both sides of one first sliding groove 111. A group of magnetic field generating components 4 can also be arranged on one side or both sides of a plurality of first sliding grooves 111. Correspondingly, a metal piece 3 corresponding to the magnetic field generating component 4 is arranged on the lens module 2. It can be understood that the more the number of magnetic field generating components 4 arranged, the greater the damping effect, and the more obvious the speed reduction effect of the lens module 2.

[0075] In some optional embodiments, the bottom wall 11 is further provided with a grounding piece 5 at a position region corresponding to the first movement stroke interval of the metal piece 3;

[0076] During the movement of the lens module 2 in the focusing stroke interval, the metal piece 3 is in the first movement stroke interval, and the metal piece 3 is in contact with and conducts with the grounding piece 5.

[0077] Exemplarily, as shown in Figure 17 and Figure 18 The focusing stroke interval is the interval L2 in the figure, the mechanical stroke interval of the lens module 2 is the interval L1 and L3 in the figure, the first movement forming interval is located in the focusing stroke interval, and the length of the first movement forming interval is the same as the length of the grounding piece 5. The grounding piece 5 is a grounding conductive metal piece. In the first running stroke interval, the eddy current formed by the metal piece 3 cutting the magnetic induction line is conducted out through the grounding piece 5, and no damping effect is formed on the metal piece 3 and the lens module 2, so as to avoid the influence of the eddy current effect on the focusing response speed; in the mechanical movement stroke interval L1 and L3 outside the focusing stroke interval L2, the eddy current formed by the metal piece 3 cutting the magnetic induction line cannot be in contact with the grounding piece 5, so as to form the damping effect on the metal piece 3 and the lens module 2, so as to reduce the movement speed of the lens module 2.

[0078] In some optional embodiments, as shown in Figure 3 Metal piece 3 includes rotating shaft 31 and metal disc 32, and metal disc 32 is fixedly connected with rotating shaft 31.

[0079] As shown in Figure 2 Lens module 2 is provided with mounting groove 21 on the side close to bottom wall 11, and rotating shaft 31 is rotatably mounted in mounting groove 21.

[0080] As shown in Figure 4 Lens module 2 is further provided with groove (not shown in the figure) for assembling metal piece 3, and mounting groove 21 of rotating shaft 31 is arranged on both sides of the groove, rotating shaft 31 is rotatably mounted in mounting groove 21, and metal disc 32 can rotate along rotating shaft 31.

[0081] Optionally, rotating shaft 31 and metal disc 32 are an integral structure, and the material is a high-conductivity metal.

[0082] Optionally, metal piece 3 plays a role of auxiliary support for lens module 2, and metal piece 3 rolls synchronously in the process that lens module 2 reciprocates along the optical axis direction.

[0083] In the above embodiments, in the process that lens module 2 reciprocates along the optical axis direction, metal disc 32 is driven to move, metal disc 32 passes through the changing non-uniform magnetic field generated by magnetic field generating component 4, eddy current can be generated in the interior of metal piece 3, the rotation of eddy current forms a secondary magnetic field which is resistant to magnetic field generating component 4, and the moving speed of metal piece 3 is reduced, so that the moving speed of lens module 2 is reduced.

[0084] In some optional embodiments, as shown in Figure 18 Metal piece 3 includes metal sliding block, and the metal sliding block is fixedly connected with lens module 2.

[0085] Optionally, the metal sliding block is a cuboid metal block.

[0086] In specific implementation, the metal sliding block can be fixedly connected with lens module 2 by assembling or injection molding. The metal sliding block does not contact frame 1 and only reciprocates in the first interval space.

[0087] In the above embodiments, in the process that lens module 2 reciprocates along the optical axis direction, metal sliding block is driven to move, metal sliding block passes through the changing non-uniform magnetic field generated by magnetic field generating component 4, eddy current can be generated, the rotation of eddy current forms a secondary magnetic field which is resistant to magnetic field generating component 4, the moving speed of metal piece 3 is reduced, and the moving speed of lens module 2 is reduced.

[0088] In some optional embodiments, the thickness of the metal piece 3 in the first direction is less than the width of the first interval space in the first direction.

[0089] The first direction is perpendicular to the optical axis direction.

[0090] As shown in Figure 9 , the first interval space between the first magnetic field generating part 41 and the second magnetic field generating part 42 in each magnetic field generating part 4 has a first interval space, and the interval (i.e. the width in the first direction) of the first interval space is greater than the thickness of the metal piece 33 in the first direction. In this way, after the lens module 2 is assembled onto the frame 1, the metal piece 3 on the lens module 2 will not contact the magnetic field generating part 4 during movement in the first interval space.

[0091] In some optional embodiments, as shown in Figure 1 , the photographing device further comprises a housing 7, the housing 7 covers the outside of the frame 1, and the housing 7 comprises a light inlet area 71.

[0092] As shown in Figure 13 and Figure 14 , which shows a schematic diagram of the housing 7 covering the outside of the frame 1. In actual implementation, the housing 7 is fixedly connected with the frame 1 through a dispensing process, so as to protect and fix the components inside the motor.

[0093] In some optional embodiments, the photographing device further comprises a light turning part 8.

[0094] The light turning part 8 is arranged in the accommodation space and corresponds to the light inlet area 71.

[0095] Optionally, the light turning part 8 is a prism for refracting light to the lens module 2.

[0096] In addition, the present application also provides an electronic device comprising a housing and a photographing device as Figures 1 to 18 described above; wherein the photographing device is located in the accommodation space of the housing.

[0097] The electronic device is equipped with the photographing device described above. In the case that the electronic device shakes under the action of external force, the lens module 2 inside the photographing device is subjected to damping action, which can reduce the moving speed of the lens module 2 and weaken the impact noise generated by the impact of the lens module 2 on other components, thereby solving the problem of excessive loudness caused by the impact of the lens module 2 on other components inside the photographing device when the electronic device shakes.

[0098] It should be pointed out that the embodiments of the present application can be applied to solve the problem of impact noise of the folded light path long-focus camera OIS anti-shake module structure, and can also be applied to solve the problem of impact noise of the straight motor focusing and OIS anti-shake module structure.

[0099] It has to be noted that, as used herein, the terms "includes" and / or "contains", or any other tautological variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements is not limited to those elements, but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. In other words, without further restriction, the element defined by the phrase "comprising a" does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element. Furthermore, it is pointed out that the scope of the methods and apparatus of the present embodiments is not limited to performing functions in the order recited or discussed, but can include performing functions in a substantially simultaneous manner or in the reverse order, e.g., the described methods can be performed in a different order than described, and various steps can be added, omitted, or combined, and features described with respect to certain examples can be combined in other examples.

[0100] From the above description of the embodiments, it is apparent that the above-described method of the embodiments can be implemented by means of software and the necessary universal hardware platform, of course, also by hardware, but in many cases the former is the better embodiment. Based on such an understanding, the technical solution of the present application, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for causing a terminal (which can be a mobile phone, computer, server, air conditioner, or network device, etc.) to execute the method described in each embodiment of the present application.

[0101] The embodiments of the present application are described above in conjunction with the drawings, but the present application is not limited to the above-described specific embodiments, which are merely illustrative, not restrictive, and those of ordinary skill in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the scope protected by the claims.
