TECHNICAL FIELD

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

[0002] The electronic equipment comprises a camera device with an anti-shake function, and the camera device comprises a magnetic stone, which is arranged on a lens. With the development of the size of a photosensitive chip of the camera device, the size of the lens is also increasing, and the size of the magnetic stone on the lens and the anti-shake stroke are also increasing. In this way, the magnetic interference problem of the mobile phone becomes more and more significant.

[0003] In the related art, the magnetic stone is arranged on the lens, the lens assembly is driven to move by moving the magnetic stone, and the magnetic field range formed by the magnetic stone also moves. The electronic equipment comprises a plurality of camera devices, and in the case that the magnetic stone moves, the spacing between two adjacent camera devices needs to be increased to ensure the effectiveness of the plurality of camera devices. In this way, the occupancy rate of the internal space of the electronic equipment is increased, and the use requirement of the thinness of the electronic equipment cannot be met.

[0004] In addition, the magnetic stone is arranged on the lens, and the automatic focusing part and the optical anti-shake photography part of the camera device need to be equipped with independent elastic systems to meet the use requirements of stable focusing and anti-shake. That is, two sets of elastic systems are needed to support the two functions of automatic focusing and optical anti-shake photography. SUMMARY

[0005] The present application aims to provide a camera device and an electronic equipment, and at least solves the technical problem that the anti-shake structure of the camera device is unreasonable in the related art, the magnetic interference problem of the electronic equipment is significant, and the use requirement of the thinness of the mobile phone cannot be met.

[0006] In order to solve the above technical problems, the present application is implemented as follows:

[0007] In a first aspect, an embodiment of the present application provides a camera device, comprising: a shell provided with a first opening; a seat body connected with the shell, a mounting cavity being enclosed between the shell and the seat body, and the mounting cavity being in communication with the first opening; a lens assembly, a part of the lens assembly extending into the mounting cavity through the first opening; a magnetic member arranged in the mounting cavity; a first coil part arranged in the lens assembly, the first coil part cooperating with the magnetic member to adjust the height of the part of the lens assembly extending out of the shell, so as to realize a focusing function; a second coil part arranged in the lens assembly, the second coil part cooperating with the magnetic member to adjust the spacing between the lens assembly and the side wall of the mounting cavity, so as to realize an anti-shake function; a first elastic member located in the mounting cavity and connected between the lens assembly and the shell; and a second elastic member located in the mounting cavity and connected between the lens assembly and the seat body.

[0008] In a second aspect, an electronic device is provided, which includes the camera device according to any of the embodiments of the first aspect.

[0009] In the embodiments of the present application, the camera device includes a housing, a seat body, a lens assembly, a magnetic piece, a first coil part, a second coil part, a first elastic piece and a second elastic piece.

[0010] The housing and the seat body enclose a mounting cavity therebetween, and the housing is provided with a first opening communicating with the mounting cavity.

[0011] Part of the lens assembly extends into the mounting cavity through the first opening, that is, after the lens assembly is assembled with the housing and the seat body, part of the lens assembly is located in the mounting cavity, and the other part of the lens assembly extends out of the housing through the first opening.

[0012] The magnetic piece is arranged on a cavity wall of the mounting cavity, the first coil part and the second coil part are both arranged on the lens assembly, and the first coil part and the second coil part are both used in cooperation with the magnetic piece. Specifically, the first coil part cooperates with the magnetic piece to adjust the height of the part of the lens assembly extending out of the housing, and the second coil part cooperates with the magnetic piece to adjust the distance between the lens assembly and the side wall of the mounting cavity. That is, the housing and / or the seat body serve as a mounting carrier of the magnetic piece, and the lens assembly serves as a mounting carrier of the first coil part and the second coil part. The position of the magnetic piece is fixed, and the lens assembly, the first coil part and the second coil part form an integral body which can move relative to the mounting cavity.

[0013] In the present application, the position of the magnetic piece is fixed, the magnetic piece does not move with the lens assembly, and the first coil part and the second coil part move with the lens assembly, that is, the first coil part, the second coil part and the magnetic piece cooperate to move the first coil part and the second coil part to drive the lens assembly to move, thereby realizing the focusing and anti-shake functions of the camera device. The fixed position of the magnetic piece can reduce external magnetic leakage and reduce magnetic interference, thereby optimizing the magnetic interference problem in the related art.

[0014] In the present application, the position of the magnetic piece is fixed, and the range of the magnetic field formed is also fixed, which is conducive to reducing the distance between two adjacent camera devices, facilitating the stacking arrangement of the devices, and realizing more extreme overall appearance design, thereby meeting the light and thin use requirements of the electronic device.

[0015] In addition, the first coil part and the second coil part share one magnetic piece, that is, while ensuring the effectiveness and feasibility of adjusting the height of the part of the lens assembly extending out of the housing and adjusting the distance between the lens assembly and the side wall of the mounting cavity, the use of the magnetic piece is reduced, the structural design difficulty of the electronic device is reduced, and the production cost of the product is reduced.

[0016] It can be understood that, in the case of energizing the first coil part, a first magnetic field is generated around the first coil part, and a second magnetic field exists around the magnetic member. Under the interaction of the first magnetic field and the second magnetic field, the first coil part is subjected to a driving thrust. The movement of the first coil part can drive the lens assembly to move in the direction from the first opening to the bottom wall of the mounting cavity (for example, the Z direction), so as to realize the focusing function of the lens assembly.

[0017] It can be understood that, in the case of energizing the second coil part, a third magnetic field is generated around the second coil part, and the second magnetic field exists around the magnetic member. Under the interaction of the third magnetic field and the second magnetic field, the second coil part is subjected to a driving thrust. The movement of the second coil part can drive the lens assembly to move in the horizontal direction (for example, the X-Y direction), so as to adjust the distance between the lens assembly and the side wall of the mounting cavity, so as to realize the anti-shake function of the lens assembly.

[0018] Further, in the present application, since the position of the magnetic member is fixed, the first coil part and the second coil part can drive the lens assembly to move relative to the mounting cavity. That is, the first elastic member, the second elastic member, the lens assembly, the magnetic member, the first coil part, the second coil part, the shell and the seat body cooperate, so that the first elastic member and the second elastic member can play a role of elastically supporting the lens assembly, so as to realize the stable focusing and anti-shake functions of the camera device. That is, the focusing function and the anti-shake function of the camera device of the present application share one set of elastic system (the elastic system includes the first elastic member and the second elastic member), and the stable focusing and stable anti-shake functions of the camera device are realized through one set of elastic system, which is conducive to reducing the structural design difficulty of the product and reducing the production cost of the product.

[0049] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 , the camera device 100 according to some embodiments of the present application comprises: a housing 110 provided with a first opening 112; a seat body 120 connected with the housing 110, the housing 110 and the seat body 120 enclosing a mounting cavity 130 therebetween, the mounting cavity 130 being in communication with the first opening 112; a lens assembly 140, a part of the lens assembly 140 extending into the mounting cavity 130 through the first opening 112; a magnetic member 150 provided in the mounting cavity 130; a first coil portion 160 provided in the lens assembly 140, the first coil portion 160 cooperating with the magnetic member 150 for adjusting the height of the part of the lens assembly 140 extending out of the housing 110 to realize focusing function; a second coil portion 170 provided in the lens assembly 140, the second coil portion 170 cooperating with the magnetic member 150 for adjusting the distance between the lens assembly 140 and the side wall of the mounting cavity 130 to realize anti-shake function; a first elastic member 180 located in the mounting cavity 130 and connected between the lens assembly 140 and the housing 110; a second elastic member 190 located in the mounting cavity 130 and connected between the lens assembly 140 and the seat body 120.

[0050] In this embodiment, the camera device 100 comprises the housing 110, the seat body 120, the lens assembly 140, the magnetic member 150, the first coil portion 160, the second coil portion 170, the first elastic member 180 and the second elastic member 190.

[0051] The housing 110 and the seat body 120 enclose the mounting cavity 130 therebetween, and the housing 110 is provided with the first opening 112 in communication with the mounting cavity 130.

[0052] Part of the lens assembly 140 extends into the mounting cavity 130 through the first opening 112, that is, after the lens assembly 140 is assembled with the shell 110 and the seat body 120, part of the lens assembly 140 is located in the mounting cavity 130, and the other part of the lens assembly 140 extends out of the shell 110 through the first opening 112.

[0053] The magnetic member 150 is arranged on the cavity wall of the mounting cavity 130, the first coil part 160 and the second coil part 170 are arranged on the lens assembly 140, and the first coil part 160 and the second coil part 170 are used in cooperation with the magnetic member 150. Specifically, the first coil part 160 cooperates with the magnetic member 150 to adjust the height of the part of the lens assembly 140 extending out of the shell 110, and the second coil part 170 cooperates with the magnetic member 150 to adjust the distance between the lens assembly 140 and the side wall of the mounting cavity 130. That is, the shell 110 and / or the seat body 120 serve as a mounting carrier of the magnetic member 150, and the lens assembly 140 serves as a mounting carrier of the first coil part 160 and the second coil part 170. The position of the magnetic member 150 is fixed, and the lens assembly 140, the first coil part 160 and the second coil part 170 form an integral body which can move relative to the mounting cavity 130.

[0054] Specifically, the magnet is arranged on the lens, and the magnet moves with the lens, which increases the magnetic interference problem of the electronic device. The position of the magnetic member 150 in the application is fixed, and the magnetic member 150 does not move with the lens assembly 140, and the first coil part 160 and the second coil part 170 move with the lens assembly 140, that is, the first coil part 160, the second coil part 170 and the magnetic member 150 cooperate, and the focusing and anti-shake functions of the camera device 100 are realized by moving the first coil part 160 and the second coil part 170 to drive the lens assembly 140 to move. The fixed position of the magnetic member 150 can reduce external magnetic leakage and reduce magnetic interference, which can optimize the magnetic interference problem in the related art.

[0055] The position of the magnet in the application is fixed, and the range of the magnetic field formed is fixed, which is beneficial to reduce the distance between two adjacent camera devices 100, facilitate the stacking arrangement of the device, realize more extreme overall appearance design, and meet the use requirement of thin and light electronic device.

[0056] In addition, the first coil part 160 and the second coil part 170 share one magnetic member 150, that is, while ensuring the effectiveness and feasibility of adjusting the height of the part of the lens assembly 140 extending out of the shell 110 and adjusting the distance between the lens assembly 140 and the side wall of the mounting cavity 130, the use quantity of the magnetic member 150 is reduced, the structural design difficulty of the electronic device is reduced, and the production cost of the product is reduced.

[0057] It can be understood that, as Figure 17 and Figure 18 shown, in the case of energizing the first coil part 160, a first magnetic field is generated around the first coil part 160, and a second magnetic field exists around the magnetic member 150. Under the interaction of the first magnetic field and the second magnetic field, the first coil part 160 is driven by a driving force, and the movement of the first coil part 160 can drive the lens assembly 140 to move in the direction (e.g., the Z direction) from the first opening 112 to the bottom wall of the mounting cavity 130, so as to realize the focusing function of the lens assembly 140.

[0058] It can be understood that, as Figure 19 and Figure 20 shown, in the case of energizing the second coil part 170, a third magnetic field is generated around the second coil part 170, and the second magnetic field exists around the magnetic member 150. Under the interaction of the third magnetic field and the second magnetic field, the second coil part 170 is driven by a driving force, and the movement of the second coil part 170 can drive the lens assembly 140 to move in the horizontal direction (e.g., the X-Y direction), so as to adjust the distance between the lens assembly 140 and the side wall of the mounting cavity 130, so as to realize the anti-shake function of the lens assembly 140.

[0059] Further, since the position of the magnetic member 150 is fixed, the first coil part 160 and the second coil part 170 can drive the lens assembly 140 to move relative to the mounting cavity 130, that is, the first elastic member 180, the second elastic member 190, the lens assembly 140, the magnetic member 150, the first coil part 160, the second coil part 170, the shell 110 and the seat body 120 cooperate, so that the first elastic member 180 and the second elastic member 190 can play a role of elastically supporting the lens assembly 140, so as to realize the stable focusing and anti-shake functions of the camera 100. That is, the focusing function and the anti-shake function of the camera 100 of the present application share a set of elastic system (the elastic system includes the first elastic member 180 and the second elastic member 190), and the stable focusing and stable anti-shake functions of the camera 100 are realized by a set of elastic system, which is conducive to reducing the structural design difficulty of the product and reducing the production cost of the product.

[0060] In some embodiments, as Figure 7 and Figure 8 shown, the first elastic member 180 includes an elastic frame 182, the elastic frame 182 is located between the lens assembly 140 and the first opening 112, and the lens assembly 140 and the shell 110 are connected with the elastic frame 182, and the part of the elastic frame 182 corresponding to the first opening 112 is provided with a avoiding opening 184; the second elastic member 190 includes a plurality of elastic parts 192, the plurality of elastic parts 192 are arranged in a circumferential direction of the lens assembly 140, and each elastic part 192 is connected between the lens assembly 140 and the seat body 120.

[0061] In this embodiment, the first elastic member 180 includes an elastic frame 182, and the second elastic member 190 includes a plurality of elastic portions 192.

[0062] The elastic frame 182 is located between the lens assembly 140 and the first opening 112, and the elastic frame 182 is connected to the lens assembly 140 and the housing 110.

[0063] The second elastic member 190 includes a plurality of elastic portions 192, each of which is connected to the lens assembly 140 and the seat body 120, i.e., each of which is connected to the lens assembly 140 and the seat body 120.

[0064] The elastic frame 182 and the plurality of elastic portions 192 cooperate to meet the use requirements of the focusing function and the anti-shake function of the camera 100. When the focusing stroke and the anti-shake stroke of the camera 100 change, the elastic frame 182 can provide system elasticity to maintain the stable operation of the camera 100. At the same time, when the focusing stroke and the anti-shake stroke of the camera 100 change, the plurality of elastic portions 192 can provide system elasticity to maintain the stable operation of the camera 100.

[0065] Specifically, the avoiding opening 184 is arranged corresponding to the first opening 112, and the lens 144 can extend out of the housing 110 through the avoiding opening 184 and the first opening 112.

[0066] In other embodiments, the first elastic member 180 can also include a plurality of elastic portions 192, which are arranged along the circumference of the lens assembly 140 and are connected between the lens assembly 140 and the housing 110.

[0067] In other embodiments, the second elastic member 190 includes an elastic frame 182, which is located between the bottom of the lens assembly 140 and the inner surface of the seat body 120 and is connected between the lens assembly 140 and the seat body 120.

[0068] In some embodiments, as shown in Figure 7 The elastic portion 192 includes a connecting rod 194 and a plurality of elastic sheets 196 arranged along the length direction of the connecting rod 194, each of which is connected between the side of the lens assembly 140 and the seat body 120.

[0069] In this embodiment, the elastic part 192 includes a connecting rod 194 and a plurality of elastic pieces 196, the plurality of elastic pieces 196 are connected with the connecting rod 194, the plurality of elastic pieces 196 are arranged along the length direction of the connecting rod 194, each elastic piece 196 is connected with the lens assembly 140, and each elastic piece 196 is connected with the seat body 120. The connecting rod 194 serves to support and position the plurality of elastic pieces 196.

[0070] This arrangement can not only meet the use requirement that the elastic part 192 is connected between the lens assembly 140 and the seat body 120, but also facilitate reducing the material input of the elastic part 192, thereby facilitating reducing the weight of the elastic part 192 and the production cost of the product.

[0071] Specifically, the second coil part 170 is electrically connected with the elastic piece 196, the circuit board assembly 200 is electrically connected with the elastic piece 196, each elastic part 192 includes the connecting rod 194 and the plurality of elastic pieces 196, and the plurality of elastic pieces 196 are arranged along the length direction of the connecting rod 194. This arrangement can meet the safety requirement of the product and facilitate ensuring the service life of the camera 100.

[0072] Specifically, the second elastic member 190 is connected with the side of the lens assembly 140, and / or the second elastic member 190 is connected with the bottom of the lens assembly 140.

[0073] In some embodiments, as shown in Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 indicated, the camera 100 further includes a circuit board assembly 200 connected with the side of the seat body 120 away from the shell 110, a flexible circuit board 210, the second coil part 170 and the circuit board assembly 200 are electrically connected through the flexible circuit board 210, and the first coil part 160 and the circuit board assembly 200 are electrically connected through the second elastic member 190.

[0074] In this embodiment, the camera 100 further includes the circuit board assembly 200 and the flexible circuit board 210.

[0075] The first coil section 160 and the circuit board assembly 200 are electrically connected via a second elastic member 190. The second elastic member 190 is not only elastic but also conductive. That is, the second elastic member 190 provides structural support for the stable focusing and image stabilization of the imaging device 100, and also serves to transmit signals and current; the second elastic member 190 can act as a power supply bridge for the first coil section 160. This arrangement allows the second elastic member 190 to have multiple functions, which helps reduce the number of components in the imaging device 100, thereby reducing production costs and processing difficulty.

[0076] Specifically, the second elastic element 190 is a metal element.

[0077] Furthermore, the second coil section 170 and the circuit board assembly 200 are electrically connected via a flexible circuit board 210. The flexible circuit board 210 serves to transmit signals and current and can act as a power supply bridge for the second coil section 170. The flexible circuit board 210 itself has a deformable structure, and its connection with the movable second coil section 170 can meet the real-time power supply requirements during movement.

[0078] Specifically, the flexible circuit board 210 is located at the bottom of the lens assembly 140.

[0079] In some embodiments, such as Figure 7 As shown, the flexible circuit board 210 is connected to the base 120, and the flexible circuit board 210 is provided with an elastic support portion 212, which is bent and arranged to support between the base 120 and the second coil portion 170.

[0080] In this embodiment, the structure of the flexible circuit board 210 is further defined such that it has an elastic support portion 212, which is supported between the base 120 and the second coil portion 170. That is, the flexible circuit board 210 also serves to support the second coil portion 170. The flexible circuit board 210 is not only elastic but also conductive. In other words, the flexible circuit board 210 can provide structural support for the stable focusing and image stabilization of the camera device 100, and can also transmit signals and current. This configuration gives the flexible circuit board 210 multiple functions.

[0081] Specifically, the elastic support 212 is bent to form a wave-shaped structure.

[0082] Specifically, the elastic support 212 is bent to form a Z-shaped structure.

[0113] Specifically, the electronic device can be a mobile terminal such as a mobile phone, a wearable device, a tablet computer, a laptop computer, a mobile computer, an augmented reality device (also referred to as an AR device), a virtual reality device (also referred to as a VR device), and a handheld game console, etc.

[0114] Specifically, the magnetic member 150 is fixed, and the lens assembly 140 is driven to move by moving the first coil part 160 and the second coil part 170 to realize anti-shake and focusing.

[0115] The flexible circuit board 210 of the present application is located at the bottom of the lens assembly 140, and can realize real-time power supply during the movement of the lens assembly 140. The flexible circuit board 210 is provided with an elastic support part 212, so that the flexible circuit board 210 has elastic deformation capability, provides a certain degree of driving force for the movement of the lens assembly 140, and ensures the smooth and controllable movement of the lens assembly 140.

[0116] The present application realizes the functions of automatic focusing and anti-shake through a set of elastic system (the elastic system includes the first elastic member 180 and the second elastic member 190), which reduces the structural complexity of the product.

The four magnetic pieces 150 are shared by the first coil part 160 and the second coil part 170. The second coil part 170 interacts with the bottom magnetic field of the magnetic piece 150 to achieve X-Y horizontal displacement.

Among them, Figure 21 The dashed arrow in the figure indicates the propagation path of the light rays, and the light rays passing through the lens 144 converge to the light-sensitive chip 204 of the circuit board assembly 200.

[0118] The lens assembly 140 is provided with power in real time by the flexible circuit board 210 during movement.

[0119] The magnetic piece 150 of the present application is fixed on the shell 110. During the anti-shake process, the magnetic piece 150 does not move, and the fixed position of the magnetic piece 150 can also weaken the external leakage magnetic field and reduce the magnetic interference.

[0120] The functions of each component of the camera 100 are described below.

In the anti-shake direction, the second coil part 170 interacts with the bottom magnetic field of the magnetic piece 150 to generate a thrust force after being powered. Due to the fixed position of the magnetic piece 150, the second coil part 170, the bracket 142 and the lens 144 as a whole are horizontally displaced, thereby realizing the anti-shake function.

[0125] The second elastic piece 190 is fixed on the bracket 142, and after the focusing stroke changes and the anti-shake stroke changes, the second elastic piece 190 can provide system elasticity to maintain system stability.

When the second coil part 170 is powered, the second coil part 170 interacts with the bottom magnetic field of the magnetic member 150 to generate a thrust. Due to the fixed position of the magnetic member 150, the second coil part 170, the support 142, and the lens 144 as a whole are horizontally displaced, so as to realize the anti-shake function.

[0128] The flexible circuit board 210 connects the second coil part 170 and the seat 120, so as to realize power supply for the second coil part 170.

[0130] The substrate 230 carries the light filtering part 240 and has the function of sealing the imaging chip 202.

[0131] The circuit board assembly 200 includes a multi-layer circuit board, a resistor, a capacitor, a driving chip, the imaging chip 202, and sensing components.

[0132] Anti-shake state: when the anti-shake work starts, the second coil part 170 includes four coil parts 174, and the four coil parts 174 are separately controlled in power-on sequence and power-on time by the driving chip, so as to realize the movement of the lens 144 movable part combination (the lens 144 movable part combination includes the lens 144, the second coil part 170, the first coil part 160, and the support 142) in the horizontal direction to perform the anti-shake movement.

[0133] Specifically, in the anti-shake state 1, the lens 144 movable part combination moves left and right in the horizontal direction. The position information of the lens 144 movable part combination is fed back in real time by the Hall element, so as to realize high-precision anti-shake.

[0134] Specifically, in the anti-shake state 2, the lens 144 movable part combination moves forward and backward in the horizontal direction. The position information of the lens 144 movable part combination is fed back in real time by the Hall element, so as to realize high-precision anti-shake.

[0135] Specifically, the lens 144 movable part combination moves up and down in the vertical direction, so as to realize the focusing function.
