Description

Technical Field

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

[0002] As users' requirements for photography continue to increase, the zoom ratios of shooting devices are becoming more diverse and the sizes are getting larger, resulting in the need for larger and larger working and moving space for lenses.

[0003] When the shooting device is not working, the lens is in a free and uncontrolled state in the cavity of the shooting device. When the shooting device shakes, the lens is in a free swinging state in the cavity, and it is easy for the lens to hit the cavity and produce abnormal noise. This abnormal noise increases with the increase of the cavity space and the weight of the lens, and the noise is obviously perceived.

[0004] At present, the following solutions are often used to solve the abnormal noise caused by impact inside the camera: Solution 1: Add flexible buffer material to the impact part. This solution has a certain noise reduction effect, but the addition of flexible components occupies the space of the lens's moving stroke, reducing the lens's movement stroke; Solution 2: Use software control measures. This solution has the problems of difficult debugging and high power consumption, which affects the battery life of the camera, and is only effective when the camera is in the power-on state, and cannot solve the problem of abnormal noise caused by impact when it is not powered on.

[0005] Therefore, how to reduce the impact noise inside the shooting device while ensuring the movement range of the lens is a technical problem that needs to be solved. Summary of the invention

[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 noise inside the photographing device while ensuring the movement range of the lens.

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

[0008] In a first aspect, an embodiment of the present application provides a photographing device, including:

[0009] A frame body, wherein the frame body forms a receiving space;

[0010] A lens module is arranged in the receiving space;

[0011] Wherein, the frame comprises: a bottom wall, on which at least one group of magnetic field generating components is arranged, each group of the magnetic field generating components comprises a first magnetic field generating component and a second magnetic field generating component which are arranged opposite to each other with a first spacing space, and the extension direction of the first spacing space is parallel to the optical axis direction of the lens module;

[0012] At least one metal piece is disposed on the lens module, and one metal piece corresponds to a group of magnetic field generating components;

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

[0014] In a second aspect, an embodiment of the present application provides an electronic device, including a housing, and a shooting device as described in the first aspect, wherein the shooting device is located in a receiving space of the housing.

[0015] In an embodiment of the present application, a shooting 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, so that the magnetic field generating components generate a non-uniform magnetic field. When the shooting device shakes, the lens module moves or rotates rapidly along the optical axis, and the metal part generates eddy currents inside the metal part by cutting the non-uniform magnetic field generated by the magnetic field generating components; the rotation of the eddy currents forms a secondary magnetic field, which is opposite to the magnetic field generated by the magnetic field generating components, and the two resist each other. When the moving metal part is subjected to an opposite force, the moving speed will be reduced, so that an effect similar to damping can be achieved. Since the metal part is fixedly connected to the lens module, the moving speed of the lens module can be reduced, and the abnormal impact sound generated by the lens module hitting other components can be weakened, thereby solving the problem of excessive loudness caused by the lens module hitting other components due to shaking inside the shooting device.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] The terms "first", "second", etc. 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 interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0041] The control method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0042] Please refer to Figures 1 to 18 , an embodiment of the present invention provides a photographing device, comprising:

[0043] A frame 1, wherein the frame 1 forms a receiving space;

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

[0045] The frame 1 includes a bottom wall 11, on which at least one group of magnetic field generating components 4 is disposed, each group of magnetic field generating components 4 includes a first magnetic field generating component 41 and a second magnetic field generating component 42 which are disposed opposite to each other with a first spacing space, and the extension direction of the first spacing space is parallel to the optical axis direction of the lens module 2;

[0046] At least one metal part 3 is disposed on the lens module 2, and one metal part 3 corresponds to a group of magnetic field generating components 4;

[0047] When the lens module 2 reciprocates along the optical axis relative to the frame 1, at least one metal part 3 reciprocates in the first spacing space, and the metal part 3 generates a magnetic force opposite to the direction of movement by cutting the non-uniform magnetic field generated by the magnetic field generating component 4.

[0048] It should be explained that the magnetic field generating component 4 can generate a changing non-uniform magnetic field. When the shooting device shakes, the lens module 2 moves or rotates rapidly along the optical axis. The metal part 3 generates eddy currents inside the metal part 3 by cutting the changing non-uniform magnetic field generated by the magnetic field generating component 4. The rotation of the eddy current will form a secondary magnetic field. According to Lenz's law, the secondary magnetic field is opposite to the magnetic field generated by the magnetic field generating component 4, and the two resist each other. After the moving metal part 3 is subjected to an opposite force, the moving speed will be reduced, so that an effect similar to damping can be achieved. Since the metal part 3 is fixedly connected to the lens module 2, the moving speed of the lens module 2 can be reduced, and the impact noise generated by the lens module 2 hitting other parts can be weakened, thereby solving the problem of excessive loudness caused by the lens module 2 hitting other parts due to shaking inside the shooting device.

[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 part 3, the smaller the resistivity of the metal part 3, and the larger the eddy current formed inside the metal part 3; the faster the speed of the metal part 3 passing through the magnetic field, the larger the eddy current formed inside the metal part 3, and the faster the lens module 2 decelerates.

[0050] In some optional embodiments, such as Figures 19 to 21 As shown, 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 extending and 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 of the first magnetic field generating component 41 and the second magnetic field generating component 42 that are located on both sides of the first spacing space and are diametrically opposed are opposite.

[0052] In one implementation, 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, the first magnetic field generating component 41 and the second magnetic field generating component 42 are respectively integrally formed magnetic structures.

[0054] For example, Fig.11 and Fig.12As shown, the first magnetic field generating component 41 and the second magnetic field generating component 42 respectively include two rows and eight columns arranged in an array, with a total of 16 magnets, and the polarities of two adjacent magnets are opposite; the first magnetic field generating component 41 and the second magnetic field generating component 42 are located on both sides of the first compartment, and the two magnets facing each other on both sides of the first compartment are set with the S pole facing the N pole. In this way, a variable non-uniform magnetic field can be formed in the first compartment.

[0055] like Fig.11 As shown, it is a schematic diagram showing that the metal member 3 moves out of the first spacing space. Fig.12 , Fig.15 and Fig.16 As shown, it is a schematic diagram showing the metal part 3 moving into the first spacing space.

[0056] It should be noted that Fig.11 and Fig.12 This is just an example. When the first magnetic field generating component 41 and the second magnetic field generating component 42 are multi-pole magnets, other magnetic pole arrangements may also be used. Figures 19 to 21 The magnetic pole arrangement shown.

[0057] As some other optional embodiments, 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 (not shown) extending and arranged parallel to the optical axis direction, the first magnetic field generating component 41 and the second magnetic field generating component 42 are located on both sides of the first interval space, and the magnetic fields generated by the two coils facing each other in the first magnetic field generating component 41 and the second magnetic field generating component 42 in the first interval space have the same direction, and the magnetic fields generated by the two adjacent coils in the first magnetic field generating component 41 and the second magnetic field generating component 42 in the first interval space have opposite directions, so that a changing non-uniform magnetic field can be generated in the first interval space.

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

[0059] The magnetic binding sheet 401 has one side fixedly connected to the bottom wall 11 ; and a multi-pole magnet is disposed on the other side of the magnetic binding sheet 401 .

[0060] For example, Figure 5 As shown, it is an exploded schematic diagram of the magnetic beam sheet 401 and the first magnetic field generating component 41 and the second magnetic field generating component 42; Figure 6 As shown, it is a schematic diagram showing the installation status of the magnetic beam sheet 401, the first magnetic field generating component 41 and the second magnetic field generating component 42.

[0061] Optionally, the magnetic beam sheet 401 is made of a magnetic conductive material, such as cold rolled low carbon steel (Cold Rolled Carbon Steel Sheet, SPCC).

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

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

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

[0065] A driving mechanism connected to the lens module 2;

[0066] With the cooperation of the driving mechanism and the guiding mechanism, the lens module 2 reciprocates relative to the frame 1 along the optical axis direction, and the lens module 2 drives at least one metal member 3 to perform a motion of cutting magnetic flux lines in the first spacing space.

[0067] Optionally, the driving mechanism includes a magnet and a coil (not shown), such as Figure 4 The middle magnet includes an N pole and an S pole 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 be driven to reciprocate along the optical axis to achieve the focusing function.

[0068] In some optional embodiments, the guiding mechanism includes:

[0069] At least two first sliding grooves 111 are provided on the bottom wall 11, and the extending direction of the first sliding grooves 111 is parallel to the optical axis direction;

[0070] At least two second slide grooves 22 are provided on the lens module 2, and the extension direction of the second slide grooves 22 is parallel to the optical axis direction; the second slide grooves 22 correspond to the first slide grooves 111 one by one, and a ball 6 is sandwiched between the first slide grooves 111 and the second slide grooves 22;

[0071] Each group of magnetic field generating components 4 is disposed on one side of the first slide slot 111 , and the extension direction of the first spacing space is parallel to or coincides with the extension direction of the first slide slot 111 and the second slide slot 22 .

[0072] For example, Figure 4 As shown, the lens module 2 is provided with three second slide grooves 22; correspondingly, three first slide grooves 111 are provided on both sides of the bottom wall 11, as shown in FIG. Figure 8 and Fig. 9As shown, the extension direction of the first slide groove 111 is parallel to the optical axis direction. The first slide groove 111 corresponds to the second slide groove 22 one by one, and a ball 6 is sandwiched between each set of the first slide groove 111 and the second slide groove 22. In this way, the first slide groove 111 and the second slide groove 22 can play a guiding role during the movement of the lens module 2, and the ball 6 can play a role in supporting the lens module 2.

[0073] For example, Fig. 9 As shown, a group of magnetic field generating components 4 are respectively arranged on both sides of the first slide slot 111, such as Figure 4 As shown, a metal piece 3 is disposed on both sides of the second slide groove 22 in the lens module 2, such as Fig.10 As shown, during the movement of the lens module 2 relative to the bottom wall 11 , at least one metal component 3 moves in the first spacing space.

[0074] It should be noted that if a plurality of first slide grooves 111 are provided on the bottom wall 11, a group of magnetic field generating components 4 may be provided only on one side of a first slide groove 111, or a group of magnetic field generating components 4 may be provided on both sides of a first slide groove 111; a group of magnetic field generating components 4 may also be provided on one side or both sides of a plurality of first slide grooves 111. Accordingly, metal parts 3 corresponding to the magnetic field generating components 4 are provided on the lens module 2. It is understandable that the more the number of magnetic field generating components 4 provided, the greater the damping effect, and the more obvious the deceleration effect of the lens module 2.

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

[0076] When the lens module 2 moves within the focusing stroke range, the metal component 3 is in the first movement stroke range, and the metal component 3 is in contact with the grounding component 5 and is conductive.

[0077] For example, Fig.17 and Fig.18 In the figure, the focus stroke interval is interval L2 in the figure, the mechanical stroke interval of the lens module 2 is intervals L1 and L3 in the figure, the first motion forming interval is located in the focus stroke interval, and the length of the first motion forming interval is the same as the length of the grounding member 5. The grounding member 5 is a grounded conductive metal member. In the first motion stroke interval, the eddy current formed by the metal member 3 cutting the magnetic flux lines is guided out through the grounding member 5, and will not form a damping effect on the metal member 3 and the lens module 2, thereby preventing the eddy current effect from affecting the focus response speed; in the mechanical motion stroke intervals L1 and L3 outside the focus stroke interval L2, the eddy current formed by the metal member 3 cutting the magnetic flux lines cannot contact the grounding member 5, so it can form a damping effect on the metal member 3 and the lens module 2, so as to reduce the movement speed of the lens module 2.

[0078] In some optional embodiments, such as Figure 3 As shown, the metal member 3 includes a rotating shaft 31 and a metal disc 32, and the metal disc 32 is fixedly connected to the rotating shaft 31;

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

[0080] like Figure 4 As shown, the lens module 2 is also provided with a groove (not shown) for assembling the metal part 3, and mounting grooves 21 of the rotating shaft 31 are provided on both sides of the groove. The rotating shaft 31 can be rotatably installed in the mounting groove 21, and the metal disc 32 can rotate along the rotating shaft 31.

[0081] Optionally, the rotating shaft 31 and the metal disc 32 are an integrated structure, and the material is a highly conductive metal.

[0082] Optionally, the metal component 3 plays a role in auxiliary support of the lens module 2 , and when the lens module 2 reciprocates along the optical axis, the metal component 3 rolls synchronously.

[0083] In the above embodiment, during the reciprocating motion of the lens module 2 along the optical axis direction, the metal disk 32 is driven to move. The metal disk 32 generates a changing non-uniform magnetic field by cutting the magnetic field generating component 4, and an eddy current is generated inside the metal part 3. The rotation of the eddy current forms a secondary magnetic field that resists the magnetic field generating component 4, thereby reducing the moving speed of the metal part 3; thereby reducing the moving speed of the lens module 2.

[0084] In some optional embodiments, such as Fig.18 As shown, the metal component 3 includes a metal slider, and the metal slider is fixedly connected to the lens module 2 .

[0085] Optionally, the metal slider is a rectangular metal block.

[0086] In specific implementation, the metal slider can be fixedly connected to the lens module 2 by assembly or injection molding. The metal slider does not contact the frame 1 and only reciprocates in the first spacing space.

[0087] In the above embodiment, during the reciprocating motion of the lens module 2 along the optical axis direction, the metal slider is driven to move. The metal slider can generate eddy current by cutting the changing non-uniform magnetic field generated by the magnetic field generating component 4. The rotation of the eddy current will form a secondary magnetic field that resists the magnetic field generating component 4, thereby reducing the moving speed of the metal part 3, thereby reducing the moving speed of the lens module 2.

[0088] In some optional embodiments, the thickness of the metal member 3 in the first direction is smaller than the width of the first spacing space in the first direction;

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

[0090] like Fig. 9 As shown, there is a first spacing space between the first magnetic field generating component 41 and the second magnetic field generating component 42 in each magnetic field generating component 4, and the spacing of the first spacing space (i.e., the width in the first direction) is greater than the thickness in the first direction of the metal component 33. In this way, it can be ensured that after the lens module 2 is assembled to the frame 1, the metal component 3 on the lens module 2 will not contact the magnetic field generating component 4 during the movement in the first spacing space.

[0091] In some optional embodiments, such as Figure 1 As shown, the photographing device further includes: a housing 7 , the housing 7 is disposed outside the frame 1 , and the housing 7 includes a light incident area 71 .

[0092] like Fig.13 and Fig.14 As shown, it is a schematic diagram showing that the housing 7 is covered outside the frame 1. In specific implementation, the housing 7 is fixedly connected to the frame 1 through a glue dispensing process to protect and fix the components inside the motor.

[0093] In some optional embodiments, the photographing device further includes: a light deflection component 8;

[0094] The light deflection component 8 is disposed in the receiving space and corresponds to the light incident area 71 .

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

[0096] In addition, the present application also provides an electronic device, including a housing, and Figures 1 to 18 The shooting device; wherein the shooting device is located in the receiving space of the shell.

[0097] By assembling the above-mentioned shooting device, when the electronic device shakes due to an external force, the lens module 2 inside the shooting device is damped, which can reduce the moving speed of the lens module 2 and reduce the abnormal impact sound caused by the lens module 2 hitting other parts, thereby solving the problem of excessive loudness caused by the lens module 2 hitting other parts inside the shooting device when the electronic device shakes.

[0098] It should be pointed out that the embodiments of the present application can be used to solve the problem of abnormal noise caused by impact of the OIS anti-shake module structural parts of a telephoto camera with a folded optical path, and can also be used to solve the problem of abnormal noise caused by impact of the upright motor focus and OIS anti-shake module structural parts.

[0099] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0100] Through the description of the above implementation methods, those skilled in the art can clearly understand that the above-mentioned embodiment methods can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, 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, a magnetic disk, or an optical disk), and includes a number of instructions for a terminal (which can be a mobile phone, a computer, a server, an air conditioner, or a network device, etc.) to execute the methods described in each embodiment of the present application.
