Description

TECHNICAL FIELD

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

[0002] With the extreme pursuit of user experience, the performance requirements of users for electronic devices such as mobile phones and tablet computers are higher and higher. Correspondingly, the performance of functional devices on electronic devices is also getting stronger and stronger. For example, with the improvement of the requirement of users for shooting effect, the large bottom camera assembly, as a camera that can obtain excellent exposure and detail performance in complex or dim light conditions, is more and more favored by users.

[0003] However, the installation of the large bottom camera assembly into the electronic device will cause the thickness of the decoration ring area of the camera assembly to increase significantly, which brings great holding discomfort to the electronic device. SUMMARY

[0004] The present application aims to provide a camera assembly and an electronic device to solve the problem of large thickness of the decoration ring area of the existing camera assembly.

[0005] In order to solve the above technical problems, the present application is implemented as follows:

[0006] In a first aspect, the present application discloses a camera assembly, comprising:

[0007] a lifting piece;

[0008] a first decoration ring connected to the lifting piece;

[0009] a camera module fixedly connected to the first decoration ring;

[0010] a second decoration ring sleeved outside the first decoration ring and arranged in opposite spaced relation to the lifting piece;

[0011] a driving mechanism connected to the lifting piece, the driving mechanism being used to drive the lifting piece to lift and lower, so as to drive the first decoration ring and the camera module to lift and lower, and in the case that the lifting piece moves to contact the second decoration ring, the lifting piece can drive the second decoration ring to lift and lower together with the first decoration ring.

[0012] In a second aspect, the present application further discloses an electronic device, comprising a device main body and the camera assembly according to any one of the above, wherein,

[0013] the camera assembly is installed on the device main body.

[0014] In the embodiment of the present application, the camera assembly can be lifted in two stages. One lifting stage is that the lifting piece drives the first decorative ring and the camera module to lift, and the other lifting stage is that the lifting piece drives the second decorative ring and the first decorative ring to lift together. Through the lifting in stages, the lifting stroke of the camera assembly can be greatly improved, a greater focal length adjustment space is provided for the camera assembly, so as to avoid setting a too large space in the camera assembly to perform the focal length adjustment operation, greatly reducing the thickness of the decorative ring area of the camera assembly. Moreover, since the first decorative ring and the second decorative ring can both be lifted in stages, the thickness of the first decorative ring and the second decorative ring can be correspondingly reduced, so that the thickness of the decorative ring area of the camera assembly can be further reduced, and a more lightweight appearance effect and better holding comfort are achieved.

[0015] Additional aspects and advantages of the application will be set forth in part in the description which follows, and in part will become apparent to those having ordinary skill in the art upon examination of the following or can be learned from practice of the application.

[0046] The embodiment of the present application provides a camera assembly which can be used to realize the function of shooting. The camera assembly can be used in an electronic device, which can include at least one of a mobile phone, a tablet computer and a wearable device, but is not limited to. The embodiment of the present application only takes the mobile phone as an example for description, and other types of electronic devices can be implemented by referring to the embodiment.

[0047] Referring to Figure 1 , a structural schematic diagram of an electronic device according to an embodiment of the present application is shown, referring to Figure 2 , an exploded structural schematic diagram of the electronic device shown in Figure 1 is shown. As shown in Figure 1 and Figure 2 , the electronic device can specifically include: a device body 2, a mainboard 3, a mainboard support 4 and a back cover 5; wherein the mainboard 3 and the mainboard support 4 can be connected on the device body 2, and the back cover 5 can be connected on the back of the device body 2 to realize the back protection of the device body 2.

[0048] In a specific application, the device body 2 as the structural body of the electronic device can specifically include a middle frame, a battery, a sub-board, a loudspeaker, a screen and the like. The mainboard 3 can be a printed circuit board, and the mainboard 3 can be used to carry electronic components. The mainboard support 4 can be used to fix the mainboard 3 and the camera assembly 1.

[0049] As shown in Figure 2As shown, the mainboard support 4 is provided with the camera assembly 1, and the rear cover 5 is provided with a through hole 51 at a position corresponding to the camera assembly 1. The camera assembly 1 can rise out of the through hole 51 to the outside of the rear cover 5, or can fall into the device main body 2 from the through hole 51.

[0050] In actual application, in the shooting process of the camera assembly 1, when the focal length needs to be adjusted, the camera assembly 1 can be raised and extended out of the rear cover 5 as needed to realize the adjustment of the focal length and obtain a satisfactory shooting effect. After the shooting is completed, the camera assembly 1 can be lowered and retracted into the device main body 2 to realize the protection of the camera assembly 1.

[0051] Referring to Figure 3 , an exploded structural schematic view of a camera assembly is shown, as Figure 3 shown, the camera assembly 1 can specifically include: a lifting piece 11; a first decorative ring 12 connected to the lifting piece 11; a camera module 13 fixedly connected to the first decorative ring 12; a second decorative ring 14 sleeved outside the first decorative ring 12 and oppositely spaced apart from the lifting piece 11; and a driving mechanism 15 connected with the lifting piece 11, which can be used to drive the lifting piece 11 to lift, so as to drive the first decorative ring 12 and the camera module 13 to lift. When the lifting piece 11 moves to contact the second decorative ring 14, the lifting piece 11 can drive the second decorative ring 14 to lift together with the first decorative ring 12.

[0052] In the embodiment of the present application, the camera assembly 1 can be lifted in two stages. One lifting stage is that the lifting piece 11 drives the first decorative ring 12 and the camera module 13 to lift, and the other lifting stage is that the lifting piece 11 drives the second decorative ring 14 and the first decorative ring 12 to lift together. Through the lifting in stages, the lifting stroke of the camera assembly 1 can be greatly improved, and a larger focal length adjustment space can be provided for the camera assembly 1. In this way, it can be avoided that a larger space is arranged in the interior of the camera assembly 1 to perform the operation of focal length adjustment, and the thickness of the decorative ring area of the camera assembly 1 can be greatly reduced. Moreover, since the first decorative ring 12 and the second decorative ring 14 can both be lifted in stages, the thickness of the first decorative ring 12 and the second decorative ring 14 can be correspondingly reduced, so that the thickness of the decorative ring area of the camera assembly can be further reduced, and a more lightweight appearance effect and better holding comfort can be realized.

[0053] Generally, the electronic device can have a first direction x, a second direction y and a third direction z which are orthogonal to each other, wherein the first direction x can be the width direction of the electronic device, the second direction y can be the length direction of the electronic device, and the third direction z can be the thickness direction of the electronic device. The camera assembly 1 can be lifted and lowered along the third direction z, i.e. the thickness direction of the electronic device.

[0054] Generally, since the second decorative ring 14 is sleeved outside the first decorative ring 12, the first decorative ring 12 can be an inner decorative ring, and the second decorative ring 14 can be an outer decorative ring. The camera module 13 contains a camera lens group, and the lifting and lowering of the camera module 13 along the third direction z can adjust the light entering and focusing of the camera module 13. Since the camera module 13 is connected to the first decorative ring 12, during the lifting and lowering of the first decorative ring 12 driven by the lifting and lowering piece 11, the camera module 13 can be correspondingly lifted and lowered to realize the adjustment of the light entering amount and the focal length.

[0055] As shown in Figure 2 The lifting and lowering piece 11 is a lifting cylinder, and the driving mechanism 15 can specifically include a driving piece 151, a gear rotating cylinder 152 and a pressure plate 153. The output end of the driving piece 151 is provided with a worm, and the worm is engaged with the skirt gear to drive the gear rotating cylinder 152 to rotate. The inner wall of the gear rotating cylinder 152 is provided with an internal gear, the lifting cylinder is located in the gear rotating cylinder 152, and the outer wall of the lifting cylinder is provided with an external gear which is engaged with the internal gear. Under the condition that the gear rotating cylinder 152 rotates, the lifting cylinder can be lifted and lowered along its axial direction. The pressure plate 153 abuts against the skirt of the gear rotating cylinder 152 to limit the lifting and lowering of the gear rotating cylinder 152.

[0056] It should be noted that in actual application, the lifting and lowering piece 11 can also be provided as a lifting rod, a lifting column or other structures capable of lifting and lowering according to the needs of those skilled in the art, and the specific form of the lifting and lowering piece 11 can not be limited in the present application.

[0057] Specifically, the driving piece 151 can be a motor, and the output end of the motor is provided with a worm. The motor can drive the worm to rotate, so as to drive the gear rotating cylinder 152 to rotate around the third direction z. Since the lifting cylinder is engaged with the gear rotating cylinder 152, the lifting cylinder can convert the rotation of the gear rotating cylinder 152 into movement along the third direction z, so as to realize the lifting and lowering of the lifting cylinder along the third direction z. The pressure plate 153 can press the skirt of the gear rotating cylinder 152 to limit the movement of the gear rotating cylinder 152 along the third direction z. The skirt of the pressure plate 153 is provided with a positioning hole and a screw hole, so as to be fixed on the mainboard support 4 by a screw.

[0058] As Figure 3 shown, the camera assembly 1 can include a chuck 16 sleeved on the first decorative ring 12 and spaced apart from the lifting piece 11, and the second decorative ring 14 is connected to the chuck 16 away from the lifting piece 11. In a specific application, the second decorative ring 14 is connected to the chuck 16, and the chuck 16 is spaced apart from the lifting piece 11. During the lifting movement of the lifting piece 11, the lifting piece 11 can only drive the first decorative ring 12 and the camera module 13 to move together to realize the first stage of lifting without the lifting piece 11 contacting the chuck 16. When the lifting piece 11 moves to abut the chuck 16, the lifting piece 11 can drive the second decorative ring 14 to move together with the first decorative ring 12 and the camera module 13 to realize the second stage of lifting. The chuck 16 can avoid the lifting piece 11 directly contacting the second decorative ring 14 to improve the movement accuracy and service life of the second decorative ring 14.

[0059] As Figure 1 shown, the camera assembly 1 can further include a first elastic member 17 connected between the second decorative ring 14 and the chuck 16 to realize the elastic connection between the second decorative ring 14 and the chuck 16. The first elastic member 17 provides buffering and shock absorption for the collision of the second decorative ring 14 during the lifting process to improve the lifting stability and lifting safety of the second decorative ring 14.

[0060] For example, the first elastic member 17 can include but is not limited to a spring, a spring sheet, and other components capable of providing elastic force. The specific type of the first elastic member 17 is not limited in the embodiments of the present application.

[0061] Referring to Figure 4 , a structural schematic view of the chuck and the second decorative ring is shown, as Figure 4 shown, the side of the chuck 16 close to the second decorative ring 14 is provided with a hollow column 161 with an opening, and the side of the hollow column 161 close to the opening is provided with a first buckle body 162; the side of the second decorative ring 14 close to the chuck 16 is provided with a positioning column 141, and the end of the positioning column 141 away from the second decorative ring 14 is provided with a second buckle body 142. The positioning column 141 is inserted into the hollow column 161, and the second buckle body 142 can be buckled with the first buckle body 162 to prevent the positioning column 141 from being pulled out of the hollow column 161.

[0062] Specifically, the connection between the second decorative ring 14 and the chuck 16 can be achieved by inserting the positioning column 141 into the hollow column 161 and preventing the positioning column 141 from being taken out of the hollow column 161. In actual applications, the first elastic member 17 can be sleeved outside the positioning column 141 and the hollow column 161, and the positioning column 141 can move in the hollow column 161 within a certain range, so as to realize the shock absorption and buffering of the second decorative ring 14.

[0063] As shown in Figure 3 , the camera assembly 1 can further include a limiting disc 18 and an image sensor 19. The limiting disc 18 is at least partially located in the lifting cylinder, and the image sensor 19 is connected to a side of the limiting disc 18 adjacent to the first decorative ring 12. In actual applications, a groove 182 can be arranged on the side of the limiting disc 18 adjacent to the first decorative ring 12, and the image sensor 19 can be embedded in the groove 182 to fix the image sensor 19 on the limiting disc 18.

[0064] Referring to Figure 5 , a structural schematic diagram of a lifting cylinder is shown, referring to Figure 6 , a structural schematic diagram of a limiting disc is shown, referring to Figure 7 , a structural schematic diagram of a first decorative ring is shown. As shown in Figure 5 , the inner wall of the lifting cylinder is provided with a wedge-shaped protruding portion 1101. As shown in Figure 6 , the limiting disc 18 is further provided with a first limiting column 181 extending towards the chuck 16. As shown in Figure 7 , the outer wall of the first decorative ring 12 is provided with a first muscle position 121, and the first limiting column 181 and the first muscle position 121 are clamped with the protruding portion 1101 to limit the rotation of the lifting cylinder.

[0065] In actual applications, the wedge-shaped protruding portion 1101 of the lifting cylinder is clamped by the first limiting column 181 and the first muscle position 121 on the outer wall of the first decorative ring 12, thereby limiting the rotation of the lifting cylinder around the third direction z.

[0066] Referring to Figure 8 , a structural schematic diagram of a chuck is shown. As shown in Figure 6 , the top of the first limiting column 181 is further provided with an arc-shaped protruding portion 183. As shown in Figure 8 , the chuck 16 is provided with an arc-shaped groove 163 at a position corresponding to the arc-shaped protruding portion 183. In the case that the chuck 16 rises to the highest point, the arc-shaped protruding portion 183 abuts against the arc-shaped groove 163 to limit the descent of the chuck 16. In this way, the second decorative ring 14 connected to the chuck 16 can be stably kept at the highest point.

[0067] AsFigure 8 As shown, the chuck 16 may also be provided with a mating groove 164, which can be used to mate with the first rib 121 and the second rib 124 on the outer wall of the first decorative ring 12 to restrict the rotation of the first decorative ring 12 around the third direction z.

[0068] like Figure 3 As shown, a second elastic element 110 is also provided between the lifting member 11 and the first decorative ring 12. The second elastic element 110 can be used to achieve an elastic connection between the lifting member 11 and the first decorative ring 12. The second elastic element 110 can realize shock absorption and buffering for the first decorative ring 12. In this way, when the lifting member 11 drives the first decorative ring 12 to rise and fall, the first decorative ring 12 can be prevented from shaking or colliding, thereby improving the lifting stability of the first decorative ring 12.

[0069] For example, the second elastic element 110 can be a spring, sheet, or other component that can provide elastic force. The specific content of the second elastic element 110 is not limited in the embodiments of this application.

[0070] like Figure 3 As shown, the camera assembly 1 may further include a bottom support ring 111 and a lens 112. The lens 112 is disposed on the side of the first decorative ring 12 away from the lifting member 11, and the lens 112 can be used to protect the camera module 13. The bottom support ring 111 is connected to the side of the first decorative ring 12 near the lifting member 11. In specific applications, the side of the bottom support ring 111 may be provided with screw holes, and the bottom support ring 111 can be fixed to the first decorative ring 12 by screws or other fasteners.

[0071] Reference Figure 9 The diagram shows a structural schematic of a bottom support ring according to an embodiment of this application, as follows. Figure 9 As shown, a second limiting post 1111 is provided on the bottom ring 111; a side groove is provided on the camera module 13, and the second limiting post 111 is inserted into the side groove to fix the camera module 13 in the first decorative ring 12 and restrict the camera module 13 from rotating and rising and falling relative to the first decorative ring 12.

[0072] like Figure 9 As shown, the bottom support ring 111 also has a first clearance notch 1112. Figure 7 As shown, a second clearance notch 123 is also provided on the skirt 122 of the first decorative ring 12. The second clearance notch 123 and the first clearance notch 1112 can be used to avoid the first limiting post 181 on the limiting plate 18, so that the first limiting post 181 can be inserted.

[0073] Reference Figure 10, a structural schematic diagram of each component of the camera assembly and a cross-sectional structural schematic diagram of different angles are shown. As shown in Figure 10 , before the camera assembly 1 is assembled, the camera module 13, the first decorative ring 12, the chuck 16, the first elastic member 17, the bottom supporting ring 111 and the lens 112 can be assembled into a whole, the second elastic member 110 is assembled on the lifting member 11, and the driving member 151, the gear rotating cylinder 152 and the pressure plate 153 in the driving mechanism 15 are assembled into a whole.

[0074] Referring to Figure 11 , an assembly schematic diagram of assembling the camera to the electronic device is shown. As shown in Figure 11 , first, the lens 112, the first decorative ring 12, the camera module 13, the chuck 16 and the bottom supporting ring 111 can be assembled into a first pre-assembly whole 100; then, the lifting member 11, the second elastic member 110, the pressure plate 153 and the gear rotating cylinder 152 are assembled to the first pre-assembly whole 100 to obtain a second pre-assembly whole 200; then, the first elastic member 17, the second decorative ring 14, the image sensor 19, the driving member 151 and the limiting disc 18 are installed to the second pre-assembly whole 200, and the pressure plate 153 is connected to the mainboard support 4 to obtain a third pre-assembly whole 300. Finally, the third pre-assembly whole 300 is installed to the device main body 2 of the electronic device, and the installation of the camera assembly 1 in the electronic device is completed.

[0075] The following provides an example of the working process of the camera assembly 1 according to the present application:

[0076] As shown in Figures 12 to 14 , in the case that the camera assembly 1 does not need to adjust the focal length or the light amount, the camera assembly 1 can be in a starting state, that is, the first decorative ring 12 and the second decorative ring 14 in the camera assembly 1 do not need to protrude out of the rear cover 5 on the device main body 2.

[0077] As shown in Figures 15 to 17 , in the case that the camera assembly 1 needs to rise to adjust the focal length or the light amount, it can first reach the first lifting state shown in Figures 15 to 17 . At this time, the driving member 151 drives the gear rotating cylinder 152 to rotate, and then drives the lifting member 11 to rise. The lifting member 11 transmits the movement in the third direction z to the first decorative ring 12 through the second elastic member 110, so as to drive the first decorative ring 12 and the internal camera module 13 to rise together until the lifting member 11 contacts the chuck 16, which is the first lifting movement stroke of the camera assembly 1.

[0078] As shown in Figures 18 to 20As shown, after the camera assembly 1 completes the first stage of lifting, it can continue to lift in the second stage, thus achieving... Figures 15 to 17 The second stage of the lifting state is shown. At this time, the lifting member 11 continues to rise, and continues to drive the first decorative ring 12 to rise through the second elastic member 110. At the same time, the lifting member 11 contacts the chuck 16 and drives the chuck 16 to rise. The chuck 16 transmits the displacement along the third direction z to the second decorative ring 14 through the first elastic member 17 and drives the second decorative ring 14 to rise. This is the second stage of the movement of the camera assembly 1, that is, the movement stroke in which the first decorative ring 12 and the second decorative ring 14 rise together.

[0079] like Figures 21 to 23 As shown, when the camera assembly 1 needs to retract after completing the shooting, the retraction can be carried out in two stages. That is, the camera assembly 1 can first move to... Figures 21 to 23 The first retracted state is described above. At this time, the drive component 151 rotates in the opposite direction, driving the gear rotating cylinder 152 to rotate in the opposite direction, thereby driving the lifting component 11 to descend. The lifting component 11 presses down on the first decorative ring 12 and drives the camera module 13, which is fixed to the first decorative ring 12, to descend together.

[0080] like Figure 24 As shown, when the second decorative ring 14 and the chuck 16 rise to their highest point, the arc-shaped groove 163 of the chuck 16 engages with the arc-shaped protrusion 183 on the top of the first limiting post 181 of the limiting plate 18. Therefore, the chuck 16 and the second decorative ring 14 are restricted by the limiting plate 18 during the first stage of the descent of the first decorative ring 12 and cannot descend on their own. This is the first stage of the movement of the camera assembly 1, namely the retraction stroke of the first decorative ring 12.

[0081] In practical applications, after the first retraction is completed, i.e., when the first decorative ring 12 has retracted, the skirt of the second decorative ring 14 contacts the chuck 16. As the drive unit 151 continues to rotate in the opposite direction, the first decorative ring 12 continues to descend, and the skirt of the second decorative ring 14 presses down on the chuck 16, causing the arc-shaped latch of the chuck 16 to disengage from the arc-shaped protrusion 183 at the top of the first limiting post 181 on the limiting plate 18. At this time, the first decorative ring 12 drives the chuck 16 and the second decorative ring 14, which is fixedly connected to the chuck 16, to descend together, eventually returning to the initial state. This is the second retraction process of the camera assembly 1, i.e., the retraction stroke of the first decorative ring 12 and the second decorative ring 14 together.

[0082] In summary, the camera assembly described in the embodiments of this application may include at least the following advantages:

[0083] In the embodiment of the present application, the camera assembly can be lifted in two stages. One lifting stage is that the lifting member drives the first decorative ring and the camera module to lift, and the other lifting stage is that the lifting member drives the second decorative ring and the first decorative ring to lift together. Through the lifting in stages, the lifting stroke of the camera assembly can be greatly improved, and a larger focal length adjustment space is provided for the camera assembly. In this way, it is possible to avoid setting a larger space inside the camera assembly to perform the focal length adjustment operation, greatly reducing the thickness of the decorative ring area of the camera assembly. Moreover, since the first decorative ring and the second decorative ring can both be lifted in stages, the thickness of the first decorative ring and the second decorative ring can be correspondingly reduced, so that the thickness of the decorative ring area of the camera assembly can be further reduced, achieving a more lightweight appearance effect and better holding comfort.

[0084] The embodiment of the present application also provides an electronic device, which can specifically include the camera assembly described in any of the above embodiments. The structure of the camera assembly is the same as that of the camera assembly described in any of the above embodiments, and the beneficial effects are similar, which will not be repeated here.
