Description

Technical Field

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

[0002] In the related technology, the closed-loop control of the optical image stabilization motor requires the addition of a Hall element inside the motor. The Hall element is a component specifically used to sense the position of the magnet. Therefore, due to the limitation of the Hall element, the optical image stabilization motor must be designed into a moving magnet form. That is, when the image stabilization is performed, the internal magnet is moving. This structure is very prone to magnetic interference. Summary of the invention

[0003] The present application aims to provide a camera device and an electronic device to solve or improve one of the technical problems of electromagnetic interference caused by the provision of a Hall element in the camera device existing in the related art.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In a first aspect, the present application provides a camera device, comprising:

[0006] case;

[0007] A driving assembly is arranged on the housing;

[0008] A lens assembly is connected to a driving assembly;

[0009] The optical resonance component is arranged on the housing and the lens component and is used to detect the displacement of the lens component. The driving component performs focusing action according to the displacement information of the lens component by the optical resonance component.

[0010] In a second aspect, the present application provides an electronic device, including:

[0011] A camera device as provided in the first aspect.

[0012] In an embodiment of the present application, a camera device includes a housing, a driving assembly, a lens assembly and an optical resonance assembly. The lens assembly is mounted on the driving assembly, and the driving assembly is mounted on the housing, so that the driving assembly can drive the lens assembly to move. An optical resonance assembly is arranged on the lens assembly and the housing, that is, a part of the optical resonance assembly is mounted on the housing, and a part of the optical resonance assembly is mounted on the lens assembly, wherein the lens assembly and the housing are relatively movable. Therefore, when the lens assembly is displaced, a certain position change occurs between the lens assembly and the housing, and then the state of the optical resonance assembly changes, so that the displacement state of the lens assembly can be detected. The driving assembly focuses the lens assembly according to the displacement information of the lens assembly detected by the optical resonance assembly, plays an anti-shake role, and improves the shooting effect of the camera device. Then, the displacement of the lens assembly is detected by using the optical resonance assembly, and there is no need to set a magnet, thereby reducing magnetic interference and reducing production costs.

[0024] Combine the following Figures 1 to 3 A camera apparatus 100 and an electronic device 300 according to an embodiment of the present application are described.

[0025] like Figure 1 As shown, the present application provides a camera device 100, including: a housing 110; a driving component 120, which is disposed in the housing 110; a lens component 130, which is connected to the driving component 120; an optical resonance component 140, which is disposed in the housing 110 and the lens component 130, and is used to detect the displacement of the lens component 130, and the driving component 120 performs a focusing action according to the displacement information of the lens component 130 by the optical resonance component 140.

[0026] In the embodiment of the present application, the camera device 100 includes a housing 110, a driving assembly 120, a lens assembly 130 and an optical resonance assembly 140. The lens assembly 130 is mounted on the driving assembly 120, and the driving assembly 120 is mounted on the housing 110, so that the driving assembly 120 can drive the lens assembly 130 to move. The optical resonance assembly 140 is arranged on the lens assembly 130 and the housing 110, that is, a part of the optical resonance assembly 140 is mounted on the housing 110, and a part of the optical resonance assembly 140 is mounted on the lens assembly 130, wherein the lens assembly 130 and the housing 110 are relatively movable. Therefore, when the lens assembly 130 is displaced, a certain position change occurs between the lens assembly 130 and the housing 110, and then the state of the optical resonance assembly 140 changes, so that the displacement state of the lens assembly 130 can be detected. The driving assembly 120 performs a focusing action on the lens assembly 130 according to the displacement information of the lens assembly 130 detected by the optical resonance assembly 140, thereby improving the shooting effect of the camera device 100, and then using the optical resonance assembly 140 to detect the displacement of the lens assembly 130, without setting a magnet, reducing magnetic interference and reducing production costs.

[0027] Specifically, the optical resonance component 140 adopts a Fabry-Perot cavity detection component.

[0028] Among them, the jitter of the lens assembly 130 is that the lens assembly 130 produces a certain displacement, and then the driving component 120 detects the displacement of the lens assembly 130 through the optical resonance component 140, so as to perform corresponding focus compensation, and form an anti-shake effect under continuous closed-loop control.

[0029] In addition, the feedback speed of the light 200 is fast, and the lens 132 improves the focusing effect of the camera device 100.

[0030] like Figure 1 and Figure 2 As shown, as a possible implementation, the optical resonance component 140 includes: an emitting structure 142 for emitting light 200; a receiving structure 150 for receiving light 200, and the emitting structure 142 and the receiving structure 150 are arranged on the lens assembly 130 and the housing 110 relative to each other.

[0031] Specifically, the optical resonance component 140 includes a transmitting structure 142 and a receiving structure 150, the transmitting structure 142 can transmit the light 200, the receiving structure 150 can receive the light 200, and the transmitting structure 142 and the receiving structure 150 are respectively arranged on the housing 110 and the lens assembly 130, so that when the lens assembly 130 is displaced, the lens assembly 130 moves relative to the housing 110, and then the transmitting structure 142 moves relative to the receiving structure 150, thereby affecting the path of the light 200, and then the receiving structure 150 can determine the displacement direction and amplitude of the lens assembly 130 according to the change in the position of the received light 200, so that real-time feedback can be performed, which is convenient for realizing closed-loop control, and the driving component 120 determines the focusing action according to the feedback of the receiving structure 150, so as to achieve the anti-shake effect of the camera device 100.

[0032] The transmitting structure 142 is disposed on the lens assembly 130 , and the receiving structure 150 is disposed on the housing 110 , thereby facilitating signal transmission of the receiving structure 150 and facilitating wiring.

[0033] like Figure 1 As shown, as a possible implementation, at least a portion of the transmitting structure 142 is embedded in one of the lens assembly 130 and the housing 110 ; at least a portion of the receiving structure 150 is embedded in the other of the lens assembly 130 and the housing 110 .

[0034] Specifically, mounting holes are provided on the shell 110 and the lens assembly 130, and at least a portion of the transmitting structure 142 and at least a portion of the receiving structure 150 are arranged in the mounting holes, thereby reducing the space occupied and having a certain light-isolating effect, reducing the interference of external light 200 on the light 200 between the transmitting structure 142 and the receiving structure 150, and improving the detection accuracy of the optical resonance component 140.

[0035] like Figure 1 and Figure 2 As shown, as a possible implementation, the emitting structure 142 includes: a light source 144; a collimating lens 146, disposed at the light-emitting end of the light source 144; a first light-transmitting member 148, disposed on the side of the collimating lens 146 away from the light source 144, and the light 200 emitted by the light source 144 passes through the collimating lens 146 and the first light-transmitting member 148, and is irradiated onto the receiving structure 150.

[0036] Specifically, the emitting structure 142 includes a light source 144, a collimating lens 146 and a first light-transmitting member 148. The collimating lens 146 is located between the light source 144 and the first light-transmitting member 148. The light source 144 can generate light 200. The light 200 forms a parallel light beam through the collimating lens 146 and then irradiates the first light-transmitting member 148, thereby irradiating the receiving structure 150. The first light-transmitting member 148 can be fixed to the lens assembly 130 by an adhesive.

[0037] The light source 144 and the collimating lens 146 may be embedded in the lens assembly 130 or the housing 110 .

[0038] Furthermore, the light source 144 is an infrared light source 144 or an ultraviolet light source 144 , thereby reducing the impact on the imaging of the camera device 100 .

[0039] Furthermore, the first light-transmitting member 148 is made of glass or plastic, and is coated with a high-reflectivity film on the side facing the receiving structure 150 to form a first reflective surface 158 , whose reflectivity is greater than 90% and transmittance is less than 10%.

[0040] Furthermore, the first light-transmitting member 148 has a wedge angle, that is, two sides of the first light-transmitting member 148 are not parallel, and form a certain angle, thereby reducing the interference of reflected light generated by the uncoated surface of the first light-transmitting member 148 .

[0041] like Figure 1 and Figure 2 As shown, as a possible implementation, the receiving structure 150 includes: a second light-transmitting member 152; a converging lens 154, which is disposed on one side of the second light-transmitting member 152; and a detector 156, which is disposed on the side of the converging lens 154 away from the second light-transmitting member 152. The detector 156 receives the light 200 emitted by the emitting structure 142 through the second light-transmitting member 152 and the converging lens 154. The second light-transmitting member 152 can be fixed to the housing 110 by an adhesive.

[0042] Specifically, the receiving structure 150 includes a second light-transmitting member 152, a converging lens 154 and a detector 156. The converging lens 154 is located between the second light-transmitting member 152 and the detector 156. The light 200 generated by the emitting structure 142 passes through the second light-transmitting member 152 and is irradiated onto the converging lens 154. The converging lens 154 converges the light 200 and irradiates the detector 156. Therefore, the detector 156 can determine the displacement of the lens assembly 130 according to the state of the light 200, thereby providing a basis for the focusing action of the driving assembly 120.

[0043] The converging lens 154 and the detector 156 may be embedded in the lens assembly 130 or the housing 110 .

[0044] In addition, the second light-transmitting member 152 is made of glass or plastic, and is coated with a high reflectivity film on the side facing the emitting structure 142 to form a second reflective surface 160, whose reflectivity is greater than 90% and transmittance is less than 10%. The first light-transmitting member 148 and the second light-transmitting member 152 are substantially parallel to each other on the opposite side. The first reflective surface 158 and the second reflective surface 160 are arranged opposite to each other.

[0045] Furthermore, the second light-transmitting member 152 has a wedge angle, thereby reducing the interference of reflected light generated by the uncoated surface of the second light-transmitting member 152. That is, the two sides of the second light-transmitting member 152 are not parallel, and form a certain angle.

[0046] Specifically, Figure 2 As shown, the light 200 generated by the light source 144 is refracted by the collimating lens 146 to form a parallel light beam, which is emitted through the first light-transmitting member 148 and irradiated on the second light-transmitting member 152. Then, the light 200 is continuously reflected on the first light-transmitting member 148 and the second light-transmitting member 152, and then multiple reflections form multiple transmissions. The multiple light beams 200 that are transmitted multiple times, and the light beams 200 that are mutually interfered with by the second light-transmitting member 152, pass through the converging lens 154, and form a detector 156. The circular interference fringes are black and white, and the interference fringes formed by the multiple beams of light 200 have a sharper definition, forming equi-inclined interference circular fringes. When the distance h between the first light-transmitting member 148 and the second light-transmitting member 152 changes, the interference fringes on the detector 156 will change. By analyzing the interference fringes and parsing the signal changes of the interference fringes, the displacement of the lens assembly 130 can be determined, which serves as the basis for the focusing action of the driving assembly 120, thereby realizing closed-loop control of the anti-shake of the camera device 100.

[0047] That is, when the lens assembly 130 is not displaced, the distance h between the first light-transmitting member 148 and the second light-transmitting member 152 is a fixed value, and after the lens assembly 130 is displaced, the distance h between the first light-transmitting member 148 and the second light-transmitting member 152 becomes smaller or larger, thereby affecting the state of the interference fringes. After analyzing the state of the interference fringes, a basis for action is provided for the driving assembly 120, focusing compensation for radial effects is achieved, and fast automatic focusing of the camera device 100 is achieved, thereby achieving the anti-shake function of the camera device 100.

[0048] like Figure 1 As shown, as a possible implementation, the driving assembly 120 includes: a magnetic member 122 disposed in the housing 110 ; a coil 124 connected to the lens assembly 130 and located on the inner side of the magnetic member 122 .

[0049] Specifically, the driving assembly 120 includes a magnetic part 122 and a coil 124. The coil 124 is connected to the lens assembly 130, and the magnetic part 122 is connected to the housing 110. When the coil 124 is energized, it can generate magnetic force with the magnetic part 122, so that the coil 124 of the lens assembly 130 drives the lens assembly 130 to move, achieving a zoom effect, thereby achieving the purpose of anti-shake.

[0050] There are multiple magnetic members 122 , and the multiple magnetic members 122 are disposed around the coil 124 .

[0051] The emitting structure 142 obtains power through the coil 124 , that is, the light source 144 and the coil 124 are electrically connected.

[0053] Specifically, the driving assembly 120 also includes a first elastic member 126 and a second elastic member 128. The two elastic members are arranged on the housing 110 and are both connected to the lens assembly 110. The first elastic member 126 and the second elastic member 128 elastically limit the lens assembly 130 so that the lens assembly 130 can move within a certain range, thereby achieving a dynamic anti-shake effect and a zoom effect.

[0054] The first elastic member 126 and the second elastic member 128 sandwich the magnetic member 122 and the lens assembly 130 . Since the coil 124 is disposed on the lens assembly 130 , the coil 124 is also located between the first elastic member 126 and the second elastic member 128 .

[0055] like Figure 1 As shown, as a possible implementation, the lens assembly 130 includes: a lens 132 ; a carrier 134 , the lens 132 is disposed on the carrier 134 , the carrier 134 is connected to the driving assembly 120 , and the optical resonance assembly 140 is disposed on the housing 110 and the carrier 134 .

[0056] Specifically, the lens assembly 130 includes a carrier 134 and a lens 132 disposed on the carrier 134, wherein the driving assembly 120 is disposed and connected to the carrier 134, the transmitting structure 142 or the receiving structure 150 is disposed on the carrier 134, and at least a portion of the transmitting structure 142 or at least a portion of the receiving structure 150 is embedded in the carrier 134, thereby improving the integrity of the lens 132 without destroying the lens 132, thereby improving the imaging effect of the camera device 100.

[0057] The first elastic member 126 and the second elastic member 128 are located on both sides of the magnetic member 122 and the carrier 134 .

[0058] like Figure 1 As shown, as a possible implementation, the housing 110 includes: a base 112; a top shell 114, which is disposed on the base 112, and the driving component 120 is installed on the top shell 114; a carrier 116, which is disposed on the base 112 or the top shell 114, and the optical resonance component 140 is disposed on the carrier 116 and the driving component 120.

[0059] Specifically, the shell 110 includes a base body 112, a top shell 114 and a carrier plate 116, the top shell 114 is arranged on the base body 112, and the carrier plate 116 is arranged on the top shell 114 or the base body 112, wherein the carrier plate 116 and the top shell 114 can be an integral structure, or the carrier plate 116 and the base body 112 can be an integral structure.

[0060] Furthermore, the transmitting structure 142 or the receiving structure 150 is disposed on the carrier 116 , and at least a portion of the transmitting structure 142 or at least a portion of the receiving structure 150 is embedded in the carrier 134 .

[0061] Further, one of the emitting structure 142 and the receiving structure 150 is disposed on the carrier 134 , and the other is disposed on the carrier 116 , so that the emitting structure 142 and the receiving structure 150 are opposite to each other, that is, the first light-transmitting member 148 and the second light-transmitting member 152 are opposite to each other.

[0062] The base 112 is provided with a filter 170 and a photosensitive chip 180. Therefore, the carrier 116 is provided on the base 112, and the receiving structure 150 is provided on the carrier 116, which can facilitate the signal output of the receiving structure 150. In addition, the light 200 in the infrared band or ultraviolet band generated by the emitting structure 142 can be filtered by the filter 170 to reduce the impact on imaging. The receiving structure 150 outputs the signal through the circuit of the photosensitive chip 180.

[0063] Specifically, the transmitting structure 142 and the receiving structure 150 are arranged along the direction from the top shell 114 to the base body 112 .
