Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment, and in particular to an electronic equipment, a photographing device and a control method thereof. Background Art

[0002] In order to obtain better shooting quality, an anti-shake mechanism is usually required in the shooting device to compensate for shooting errors caused by reasons such as hand shaking during shooting. In the related art, in order to achieve anti-shake, a sensor is usually used to detect the position of the lens, and a coil drives the magnet to drive the lens to move. The sensor and the coil are both arranged on the circuit board. As users have higher and higher requirements for the performance of shooting devices, the lenses are also getting larger, which requires the driving force of the coil to drive the lens to be greater. Since the driving force of the coil on the lens needs to be increased, the number of turns of the coil needs to be increased, which leads to an increase in the thickness of the coil. In addition, a larger gap needs to be set between the circuit board and the magnet to accommodate the thicker coil. However, the sensor is arranged on the circuit board. As the distance between the circuit board and the magnet increases, the distance between the sensor and the magnet also increases, which reduces the accuracy of the sensor in detecting the position of the lens, thereby reducing the anti-shake accuracy of the shooting device. Summary of the Invention

[0003] The present invention discloses an electronic device, a shooting device and a control method thereof, so as to solve the problem of low anti-shake accuracy of the shooting device in the related art.

[0004] In order to solve the above-mentioned technical problems, the present invention is achieved as follows:

[0005] In a first aspect, the present application discloses a photographing device, comprising: a lens, a magnet, an electromagnetic coil group, a sensor and a circuit board, wherein the lens is connected to the magnet, and the lens and the magnet are both located on a first side of the circuit board; the electromagnetic coil group is arranged on the circuit board, and a first part of the electromagnetic coil group is located on the first side of the circuit board and opposite to the magnet; a second part of the electromagnetic coil group is located on the second side of the circuit board, and the first side of the circuit board and the second side of the circuit board are opposite to each other; the sensor is arranged on the circuit board, and the sensor is used to detect the position of the magnet; the electromagnetic coil group drives the magnet to drive the lens to move.

[0006] In a second aspect, the present application discloses an electronic device comprising the photographing device described in the first aspect.

[0007] In a third aspect, the present application discloses a control method for a camera device, wherein the camera device is the camera device described in the first aspect, wherein the first portion and the second portion are separate structures, the first portion is a first electromagnetic coil, the second portion is a second electromagnetic coil, and the first electromagnetic coil and the second electromagnetic coil can be independently energized;

[0008] The control method includes:

[0009] controlling the sensor to detect the position of the magnet;

[0010] detecting an offset distance of the magnet;

[0011] When the offset distance of the magnet is less than a threshold, controlling the first electromagnetic coil to drive the magnet to move the lens;

[0012] When the offset distance of the magnet is greater than a threshold, the first electromagnetic coil and the second electromagnetic coil are controlled to jointly drive the magnet to drive the lens to move.

[0013] The technical solution adopted by the present invention can achieve the following technical effects:

[0014] The camera device disclosed in the embodiment of the present application, by arranging a portion of the electromagnetic coil assembly on the first side of the circuit board and another portion on the second side of the circuit board, can avoid the problem that when the electromagnetic coil assembly is entirely on the first side of the circuit board, the distance between the magnet and the sensor is too large to avoid interference with the electromagnetic coil assembly, thereby resulting in poor accuracy in detecting the position of the magnet by the sensor. It can also avoid the problem that when the electromagnetic coil assembly is entirely on the second side of the circuit board, the distance between the electromagnetic coil assembly and the magnet is too large, resulting in a reduction in the ability of the electromagnetic coil assembly to drive the magnet to move. The camera device disclosed in the embodiment of the present application, by arranging a portion of the electromagnetic coil assembly on the first side of the circuit board and another portion on the second side of the circuit board, does not need to locate the entire thick electromagnetic coil assembly between the circuit board and the magnet, thereby increasing the distance between the circuit board and the magnet, and further increasing the distance between the sensor and the magnet. As a result, the distance between the sensor and the magnet is reduced, thereby improving the accuracy of the sensor in detecting the position of the magnet. It can also avoid the distance between the electromagnetic coil assembly and the magnet being too large, thereby improving the ability of the electromagnetic coil assembly to drive the magnet, and thus improving the anti-shake performance of the camera device.

[0030] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of this application.

[0031] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0032] The following describes in detail the photographing device provided in the embodiment of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0033] Please refer to Figures 1 to 5 An embodiment of the present invention discloses a photographing device, which includes: a lens, a magnet 100, an electromagnetic coil assembly 200, a sensor 300 and a circuit board 400.

[0034] The lens is connected to the magnet 100. The lens and magnet 100 can be fixedly or flexibly connected. This application does not impose any specific restrictions on the connection method between the lens and magnet 100. The lens and magnet 100 are both located on the first side of the circuit board 400. The electromagnetic coil assembly 200 is disposed on the circuit board 400. When energized, the electromagnetic coil assembly 200 can magnetically cooperate with the magnet 100, driving the magnet 100 to drive the lens movement.

[0035] The first portion 210 of the electromagnetic coil assembly 200 is located on a first side of the circuit board 400 and opposite to the magnet 100 . The second portion 220 of the electromagnetic coil assembly 200 is located on a second side of the circuit board 400 . The first side of the circuit board 400 and the second side of the circuit board 400 are opposite to each other.

[0036] The sensor 300 is disposed on the circuit board 400. The sensor 300 is used to detect the position of the magnet 100. The electromagnetic coil assembly 200 drives the magnet 100 to move the lens.

[0037] It should be noted that the camera device usually shakes along with the person's limbs when shooting. After the sensor 300 detects the position of the magnet 100, the offset distance of the magnet 100 can be determined. In the embodiment of the present application, since the lens is provided on the magnet 100, after the position of the magnet 100 is detected, the position of the lens can also be determined accordingly. The offset distance of the magnet 100 is the offset distance of the lens. Thus, the offset distance of the lens relative to the preset position can be determined. The preset position can be the position of the lens on the camera device when the camera device is not shaking. The electromagnetic coil assembly 200 can drive the magnet 100 to move the lens according to the detected position of the magnet 100, so that the lens moves to the preset position. Therefore, when the camera device shakes, the anti-shake movement of the lens can be achieved through the cooperation of the electromagnetic coil assembly 200 and the magnet 100. The anti-shake movement here can be anti-shake movement or anti-shake rotation. The present application does not limit the form of the anti-shake movement.

[0038] The shooting device disclosed in the embodiment of the present application can avoid the problem that when the electromagnetic coil group 200 is entirely located on the first side of the circuit board 400, the distance between the magnet 100 and the sensor 300 is too large in order to avoid interference with the electromagnetic coil group 200, thereby resulting in poor position accuracy of the magnet 100 detected by the sensor 300; it can also avoid the problem that when the electromagnetic coil group 200 is entirely located on the second side of the circuit board 400, the distance between the electromagnetic coil group 200 and the magnet 100 is too large, resulting in a reduced ability of the electromagnetic coil group 200 to drive the magnet 100 to move. The shooting device disclosed in the embodiment of the present application arranges a portion of the electromagnetic coil group 200 on the first side of the circuit board 400 and the other portion on the second side of the circuit board 400. In this way, there is no need to place the entire electromagnetic coil group 200 with a larger thickness between the circuit board 400 and the magnet 100, and there is no need to increase the distance between the circuit board 400 and the magnet 100, and further, there is no need to increase the distance between the sensor 300 and the magnet 100, so that the distance between the sensor 300 and the magnet 100 is smaller, thereby improving the accuracy of the sensor 300 in detecting the position of the magnet 100, and avoiding the distance between the electromagnetic coil group 200 and the magnet being too large, thereby improving the driving ability of the electromagnetic coil group 200 on the magnet 100, and further improving the anti-shake performance of the shooting device.

[0039] In an optional embodiment, the electromagnetic coil assembly 200 can be an integral structure, that is, the first part 210 and the second part 220 can be an integral structure, the circuit board 400 can be provided with an opening, and the electromagnetic coil assembly 200 can be inserted into the opening, thereby realizing the installation of the electromagnetic coil assembly 200.

[0040] To avoid reducing the strength of circuit board 400 due to openings in circuit board 400, the first portion 210 and the second portion 220 may optionally be separate structures. The first portion 210 may be the first electromagnetic coil, and the second portion 220 may be the second electromagnetic coil. The circuit board 400 may be located between the first and second electromagnetic coils to separate the first and second electromagnetic coils. Alternatively, the first side of circuit board 400 may have a first soldering portion 410, and the second side of circuit board 400 may have a second soldering portion 420. The first portion 210 may be soldered to the first soldering portion 410, and the second portion 220 may be soldered to the second soldering portion 420.

[0041] The shooting device disclosed in the embodiment of the present application is configured to have a split structure with the first part 210 and the second part 220 of the electromagnetic coil assembly 200, so that the first part 210 and the second part 220 can be installed independently, thereby facilitating the installation of the electromagnetic coil assembly 200 on the circuit board 400 and avoiding the need to open holes in the circuit board 400, thereby facilitating the improvement of the strength of the circuit board 400.

[0042] In some application scenarios (such as a user sitting in a moving car holding an electronic device to shoot), the camera shakes relatively widely, and the electromagnetic coil assembly 200 requires a relatively large magnetic field to drive the magnet 100 to move the lens. In other scenarios (such as a user standing on the ground holding an electronic device to shoot), the camera shakes relatively little, and the electromagnetic coil assembly 200 only needs to generate a relatively small magnetic field to drive the magnet 100 to move the lens. If the electromagnetic coil assembly 200 only generates a relatively large magnetic field when the current flowing through the electromagnetic coil is constant, then when the camera shakes relatively little, the electromagnetic coil assembly 200 will suffer a significant energy loss. If the electromagnetic coil assembly 200 only generates a relatively small magnetic field, then when the camera shakes relatively much, it will not be able to provide sufficient driving force to drive the magnet 100 to move the lens. To avoid significant energy loss in the electromagnetic coil assembly 200 and to prevent the electromagnetic coil assembly 200 from being unable to provide sufficient driving force to drive the magnet 100 to move the lens, the first and second electromagnetic coils can optionally be energized independently, so that the camera has a first anti-shake mode and a second anti-shake mode. When the camera is in the first anti-shake mode, the first electromagnetic coil can drive the magnet 100 to move the lens. When the camera is in the second anti-shake mode, the first and second electromagnetic coils can jointly drive the magnet 100 to move the lens.

[0043] It should be noted that the first anti-shake mode may be applied to a situation where the shaking of the shooting device is relatively small, and the second anti-shake mode may be applied to a situation where the shaking of the shooting device is relatively large.

[0044] The camera device disclosed in the embodiment of the present application is configured to independently energize the first and second electromagnetic coils. This allows the camera device to be in a first anti-shake mode when the camera shakes slightly. Since only a small driving force is required to drive the magnet 100 to move the lens, only the first electromagnetic coil is used to drive the magnet 100 to move the lens, thereby reducing the energy consumption of the electromagnetic coil assembly 200. Furthermore, the first electromagnetic coil is located on a side close to the magnet 100, thereby effectively driving the magnet 100 to move the lens. When the camera shakes significantly, the camera device can be in a second anti-shake mode. At this time, the first and second electromagnetic coils jointly drive the magnet 100 to move the lens, thereby effectively driving the electromagnetic coil assembly 200 to drive the magnet 100 to move the lens.

[0045] In order to accurately determine whether the shooting device activates the first anti-shake mode or the second anti-shake mode, optionally, when the offset distance of the magnet 100 is less than a threshold value (equivalent to the offset distance of the lens being less than the threshold value), the shooting device activates the first anti-shake mode; when the offset distance of the magnet 100 is greater than the threshold value (equivalent to the offset distance of the lens being greater than the threshold value), the shooting device activates the second anti-shake mode.

[0046] It should be noted that the offset distance can be calculated after the position of the magnet 100 is detected. The threshold value can be set manually, for example, the threshold value can be 1mm, 2mm, etc., and the embodiment of the present application does not limit the setting of the threshold value.

[0047] The shooting device disclosed in the embodiment of the present application enables the first anti-shake mode when the offset distance of the magnet 100 is less than a threshold; and enables the second anti-shake mode when the offset distance of the magnet 100 is greater than the threshold, thereby making the shooting device more accurate in enabling the anti-shake mode.

[0048] In an optional embodiment, the electromagnetic coil assembly 200 drives the magnet 100 to move the lens along a first direction, the sensor 300, the circuit board 400 and the electromagnetic coil assembly 200 can be arranged along the first direction, and the optical axis of the lens can be perpendicular to the first direction.

[0049] The shooting device disclosed in the embodiment of the present application arranges the sensor 300, the circuit board 400 and the electromagnetic coil assembly 200 along a first direction, so that the electromagnetic coil assembly 200 drives the magnet 100 to drive the lens to move along the first direction perpendicular to the optical axis of the lens, thereby achieving anti-shake of the lens in the direction perpendicular to the optical axis.

[0050] To facilitate the installation of various components of the shooting device, optionally, the shooting device may include a base 500 and a lens holder 600, the lens holder 600 may be movably arranged on the base 500, the lens and the magnet 100 may both be arranged on the lens holder 600, the circuit board 400 may be arranged on the base 500, the electromagnetic coil group 200 and the sensor 300 may both be opposite to the outer wall of the lens, and the electromagnetic coil group 200 may drive the magnet 100 to drive the lens to move.

[0051] It should be noted that the electromagnetic coil assembly 200 drives the magnet 100 to drive the lens to move, and the electromagnetic coil assembly 200 drives the magnet 100 to drive the lens holder 600 to move relative to the base 500, so that the lens holder 600 drives the lens to move.

[0052] The shooting device disclosed in the embodiment of the present application is provided with a base 500 and a lens holder 600, so that the lens holder 600 can be movably arranged on the base 500, the lens and the magnet 100 can both be arranged on the lens holder 600, and the circuit board 400 can be arranged on the base 500, so that the base 500 and the lens holder 600 can provide a foundation for installing the various components of the shooting device.

[0053] Specifically, the lens bracket 600 may include a first bracket 610 and a second bracket 620. The first bracket 610, the second bracket 620 and the base 500 are stacked in sequence. The first bracket 610 and the second bracket 620 can be connected by ball rolling. The second bracket 620 and the base 500 can be connected by ball rolling. The magnet 100 is arranged on the first bracket 610.

[0054] In order to improve the anti-shake performance of the shooting device, optionally, the circuit board 400, the electromagnetic coil group 200, the sensor 300 and the magnet 100 can be multiple, and multiple circuit boards 400, multiple electromagnetic coil groups 200, multiple sensors 300 and multiple magnets 100 can be arranged in a one-to-one correspondence and arranged around the optical axis of the lens.

[0055] The shooting device disclosed in the embodiment of the present application can achieve anti-shake performance of the lens in multiple directions by providing a plurality of circuit boards 400, electromagnetic coil groups 200, sensors 300 and magnets 100, and arranging them around the optical axis of the lens, thereby improving the anti-shake performance of the shooting device.

[0056] In order to further improve the accuracy of the sensor 300 in detecting the position of the magnet 100, optionally, the sensor 300 can be located on the first side of the circuit board 400, the sensor 300 can have a first height in the direction away from the second side of the circuit board 400, and the first part 210 can have a second height in the direction away from the second side of the circuit board 400, and the second height is less than or equal to the first height.

[0057] The shooting device disclosed in the embodiment of the present application arranges the sensor 300 on the first side of the circuit board 400, and the height of the first part 210 is less than or equal to the second height of the sensor 300, so that the first part does not interfere with the layout of the magnet 100, thereby facilitating setting the distance between the sensor 300 and the magnet 100 to the minimum, thereby improving the accuracy of the sensor 300 in detecting the position of the magnet 100.

[0058] Of course, in another embodiment, the sensor 300 may be disposed on the second side of the circuit board 400 .

[0059] Specifically, the sensor 300 can be disposed in the area surrounded by the electromagnetic coil assembly 200 , thereby making the structure of the photographing device more compact.

[0060] The present application also discloses an electronic device, comprising the camera disclosed in the above-mentioned embodiment. The electronic device disclosed in the embodiment of the present application, provided with the camera disclosed in the above embodiment, can reduce the distance between the sensor 300 and the magnet 100, thereby improving the accuracy of the sensor 300 in detecting the position of the magnet 100. It can also prevent the electromagnetic coil assembly 200 from being too far away from the magnet, thereby improving the driving ability of the electromagnetic coil assembly 200 on the magnet 100, and further improving the anti-shake performance of the camera.

[0061] In order to make full use of the magnet 100, optionally, the sensor 300 can be a Hall sensor, which can determine the position of the magnet 100 according to the change of the magnetic field of the magnet 100, thereby making full use of the magnetic field generated by the magnet 100, so that the magnet 100 can be fully utilized.

[0062] In the embodiment of the present application, the sensor 300 may also be an infrared sensor, a pressure sensor, etc. The embodiment of the present application does not impose any specific restrictions on the type of the sensor 300.

[0063] Please refer to Figure 6 This application also discloses a control method for a camera device. The disclosed camera device is the camera device disclosed in the above embodiment. The first part 210 and the second part 220 are split structures. The first part 210 is a first electromagnetic coil, and the second part 220 is a second electromagnetic coil. The first electromagnetic coil and the second electromagnetic coil can be energized independently. The disclosed control method includes:

[0064] S101 , controlling the sensor 300 to detect the position of the magnet 100 .

[0065] It should be noted that the implementation method of the sensor 300 detecting the position of the magnet 100 has been disclosed in the above embodiments, and they can be referenced with each other, so they will not be repeated here.

[0066] S102 , detecting the offset distance of the magnet 100 .

[0067] It should be noted that after the position of the magnet 100 is detected, the offset distance of the magnet 100 can be obtained by calculation.

[0068] S103 , when the offset distance of the magnet 100 is less than a threshold, controlling the first electromagnetic coil to drive the magnet 100 to drive the lens to move.

[0069] S104 , when the offset distance of the magnet 100 is greater than a threshold, controlling the first electromagnetic coil and the second electromagnetic coil to jointly drive the magnet 100 to drive the lens to move.

[0070] The control method for a camera device disclosed in an embodiment of the present application sets the first electromagnetic coil and the second electromagnetic coil to be independently energized, so that when the camera device shakes slightly, the camera device is in a first anti-shake mode. Since only a small driving force is required to drive the magnet 100 to drive the lens movement, only the first electromagnetic coil is used to drive the magnet 100 to drive the lens movement, thereby reducing the energy consumption of the electromagnetic coil assembly 200. In addition, the first electromagnetic coil is located on the side close to the magnet 100, so that the magnet 100 can be driven to drive the lens movement better. When the camera device shakes significantly, the camera device can be placed in a second anti-shake mode. At this time, the first electromagnetic coil and the second electromagnetic coil jointly drive the magnet 100 to drive the lens movement, so that the electromagnetic coil assembly 200 can better drive the magnet 100 to drive the lens movement.

[0071] The shooting device in the embodiment of the present application can be a device with an operating system. The operating system can be an Android operating system, an iOS operating system, or other possible operating systems, which are not specifically limited in the embodiment of the present application.

To avoid repetition, it will not be repeated here.
