Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to an electronic device. Background Art

[0002] With the continuous improvement of the imaging functions of electronic devices such as mobile phones, the demand for taking photos with electronic devices is also increasing, and photo-taking scenes are emerging in an endless stream. In order to improve the shooting performance of electronic devices, the lens of the camera module can be retracted to achieve the zoom function of the camera module. In order to cooperate with the retraction of the lens of the camera module, the camera decoration of the electronic device is also set to a liftable structure, so that the protruding height of the camera decoration relative to the housing of the electronic device is small, which is conducive to the thinness of the electronic device.

[0003] In the related art, a decorative part driving mechanism is provided inside the electronic device, and the decorative part driving mechanism can cooperate to drive the decorative part to extend and retract when the lens of the camera module extends and retracts. In the related art, the driving mechanism includes a motor and a lead screw, and the motor drives the lead screw to rotate, and the lead screw drives the camera decorative part to rise and fall along the thickness direction of the electronic device.

[0004] However, the movement stroke of the camera decoration depends on the size of the thread of the screw along the movement direction of the decorative ring. Therefore, in order to increase the lifting range of the decorative ring, a large-sized screw must be used, which will occupy more space in the thickness direction of the electronic device, thereby making the electronic device thicker. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide an electronic device that can solve the technical problem of the large thickness of the electronic device.

[0006] In order to solve the above technical problems, this application is implemented as follows: The present application discloses an electronic device, comprising: A device housing and a camera decoration, wherein the device housing is provided with a receiving space and an opening communicating with the receiving space, and the camera decoration is installed in the opening; A decoration driving mechanism, wherein the decoration driving mechanism is located in the accommodating space, and the decoration driving mechanism comprises a driving source and a chain group, wherein the mutually meshing areas of the multiple chains in the chain group constitute a rigid chain column structure, and the unmeshed area of ​​each chain in the chain group is a flexible chain structure; the rigid chain column structure is connected to the camera decoration; the driving source is drivingly connected to at least one of the chains in the chain group; the driving source drives at least one of the chains to move so as to increase or shorten the length of the rigid chain column structure, so as to drive the camera decoration to move relative to the device housing along the axial direction of the opening.

[0007] In an embodiment of the present application, the decorative part driving mechanism includes a driving source and a chain group, wherein the mutually meshing area of ​​the multiple chains in the chain group constitutes a rigid chain column structure, and the unmeshed area of ​​each chain in the chain group is a flexible chain structure. The rigid chain column structure is connected to the camera decorative part. When the camera decorative part is in a non-lifting condition, the travel segment of each chain is stored in the accommodating space in a flexible chain structure. When the camera decorative part needs to be raised, the meshing area of ​​the chain increases under the drive of the driving source, so the travel segment is converted from the flexible chain structure to the rigid chain column structure, and the length of the rigid chain column structure increases and lifts the camera decorative part. When the camera decorative part needs to be retracted, the driving source drives the travel segment to be converted from the rigid chain column structure to the non-meshing flexible chain structure, and the length of the rigid chain column structure is shortened, thereby causing the camera decorative part to drop. In this scheme, the travel segment of the chain used to drive the camera decoration to rise and fall can be stored in the accommodating space in a flexible chain structure. Since the flexible chain structure can bend or curl, the lifting and falling travel of the camera decoration can be arranged in a non-thickness direction, thereby reducing the space in the thickness direction of the electronic device, and then reducing the thickness of the electronic device to achieve a lightweight and thin electronic device.

DETAILED DESCRIPTION

[0010] The following will be combined with the 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, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0011] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0012] The fill light and the electronic device provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0013] Please refer to Figures 1 to 15 An embodiment of the present application discloses an electronic device, which includes a device housing 100, a camera decoration 200 and a decoration driving mechanism 300.

[0014] The device housing 100 provides a mounting base for other components of the electronic device. Device housings 100 of different structures form different components. For example, the device housing 100 may include a front shell, a back cover, and a middle frame disposed between the two. For another example, the device housing 100 includes a front cover and a back cover, and the aforementioned middle frame may be formed on the front cover or the back cover, that is, the middle frame may be integrally formed with the front cover or the back cover, and the back cover here may also be understood as a battery cover. The device housing 100 is provided with a receiving space 101 and an opening 102 connected to the receiving space 101. The receiving space 101 is used to install related electronic devices of the electronic device, such as components such as a camera module 500 and a circuit board 400. The camera decorative member 200 is installed in the opening 102, and the camera module 500 is disposed opposite to the light-transmitting area of ​​the camera decorative member 200. The camera decorative member 200 here is used to cover the camera module 500 disposed inside the device housing 100. At this time, the external ambient light passes through the light-transmitting area on the camera decoration 200 and enters the lens of the camera module 500, thereby realizing the shooting function.

[0015] In an electronic device, a rear camera module 500 is usually provided with a camera decoration 200, so the camera decoration 200 is provided on the back of the device housing 100. The back of the device housing 100 refers to the side of the device housing 100 away from the display module. Therefore, the above-mentioned opening 102 is provided on the back of the device housing 100, which can also be understood as the opening 102 being provided on the back cover.

[0016] The decorative member driving mechanism 300 is located in the accommodation space 101, and is used to drive the camera decorative member 200 to move relative to the device housing 100 along the axial direction of the opening 102. At this time, when the lens of the camera module 500 is extended, the decorative member driving mechanism 300 drives the camera decorative member 200 to rise to the first position; when the lens of the camera module 500 is retracted, the decorative member driving mechanism 300 drives the camera decorative member 200 to fall to the second position. By lifting and lowering the camera decorative member 200, the protruding height of the camera decorative member 200 relative to the device housing 100 of the electronic device is reduced, which is conducive to the thinness of the electronic device.

[0017] The decorative part driving mechanism 300 includes a driving source 310 and a chain group 320. The mutually meshing areas of the multiple chains in the chain group 320 constitute a rigid chain column structure 3201. The mutually meshing areas of the multiple chains can support each other, thus forming a columnar and rigid structure. The rigid chain column structure 3201 is rigid, so the rigid chain column structure 3201 has supporting performance. The unmeshed area of ​​each chain in the chain group 320 is a flexible chain structure 3202, and the unmeshed area of ​​each chain is in a flexible state, so it is a flexible chain structure 3202. It can also be understood here that the chains are in a flexible state when they are not meshed with each other.

[0018] The rigid chain column structure 3201 is connected to the camera decoration 200, and one end of the rigid chain column structure 3201 away from the flexible chain structure 3202 is connected to the camera decoration 200. The driving source 310 is drivingly connected to at least one chain in the chain group 320. The driving source 310 can drive at least one chain to move so that the length of the rigid chain column structure 3201 increases or decreases, thereby driving the camera decoration 200 to move relative to the device housing 100 along the axial direction of the opening 102.

[0019] In the specific operation process, when the camera decoration 200 is in the non-raised second position, the length of the rigid chain column structure 3201 is the first length, and the first length is the basic length of the rigid chain column structure 3201. The rigid chain column structure 3201 of the first length supports the camera decoration 200 in the second position. When the camera decoration 200 needs to be raised, the driving source 310 drives at least one chain to move. Since the multiple chains are meshed with each other, at least one moving chain will drive all the chains to move together, so that the area where the multiple chains are meshed with each other increases, thereby increasing the length of the rigid chain column structure 3201. When the camera decoration 200 switches to the first position, the length of the rigid chain column structure 3201 is the second length, and the difference between the second length and the first length here is the travel section for lifting the camera decoration 200. When the camera decoration 200 descends, the area where the multiple chains are meshed with each other gradually separates, thereby shortening the length of the rigid chain column structure 3201, so that the camera decoration 200 returns to the second position.

[0020] In the embodiment disclosed in the present application, when the camera decoration 200 is in a non-lifting condition, the travel segment of each chain is stored in the accommodation space 101 in the flexible chain structure 3202. When the camera decoration 200 needs to be lifted, the meshing area of ​​the chain increases under the drive of the driving source 310, so the travel segment is converted from the flexible chain structure 3202 to the rigid chain column structure 3201, and the length of the rigid chain column structure 3201 increases and lifts the camera decoration 200. When the camera decoration 200 needs to be retracted, the driving source 310 drives the travel segment to be converted from the rigid chain column structure 3201 to the non-engaged flexible chain structure 3202, and the length of the rigid chain column structure 3201 is shortened, thereby causing the camera decoration 200 to drop. At this time, the travel segment of the chain used to drive the camera decoration 200 to rise and fall can be stored in the accommodating space 101 in the flexible chain structure 3202. Since the flexible chain structure 3202 can be bent or curled, the lifting and lowering travel of the camera decoration 200 can be arranged in a non-thickness direction, thereby reducing the space in the thickness direction of the electronic device, and then reducing the thickness of the electronic device to achieve a lightweight electronic device.

[0021] For example, the flexible chain structure 3202 can be stored in the width direction of the electronic device, or stored in the length direction of the electronic device. Of course, the reel can also be set in the device housing 100.

[0022] Compared with the solutions in the prior art, the decorative part driving mechanism 300 in the present application has a lifting stroke of the camera decorative part 200 arranged in a non-thickness direction, so the decorative part driving mechanism 300 disclosed in the present application has a higher telescopic ratio. In addition, the lifting operation is achieved by the meshing switching between the chains, so that the structure of the decorative part driving mechanism 300 is also simpler, and the assembly difficulty and cost are lower. In addition, compared with the solutions in the related art, the decorative part driving mechanism 300 in the present application has a shorter transmission chain, so the transmission efficiency is higher.

[0023] In another optional embodiment, the electronic device may further include an elastic member 600, and the elastic member 600 may be located in the accommodating space 101. One end of the elastic member 600 may be connected to the camera decoration 200, and the other end of the elastic member 600 may be connected to the device housing 100. At this time, when the decoration drive mechanism 300 drives the camera decoration 200 to rise, the length of the elastic member 600 becomes longer; when the decoration drive mechanism 300 drives the camera decoration 200 to fall, the length of the elastic member 600 becomes shorter. It should be noted here that when the camera decoration 200 is in the first position or the second position, the supporting force of the rigid chain column structure 3201 and the elastic force of the elastic member 600 are a pair of balancing forces, thereby ensuring that the camera decoration 200 remains in the current position.

[0024] In this solution, the elastic member 600 can provide buffering and auxiliary support for the camera decoration member 200, thereby avoiding the risk of the camera decoration member 200 being damaged by a rigid collision.

[0025] In a specific application environment, when the camera decorative part 200 is in the second position and is subjected to external impact force, the elastic part 600 and the rigid chain column structure 3201 provide reliable support for the camera decorative part 200, thereby preventing the camera decorative part 200 from being damaged by the impact force. When the decorative ring 210 is subjected to external impact in the first position, after the impact force exceeds the preset torque of the driving source 310, the electronic device can send an electrical signal to control the camera to retract quickly, and then the driving source 310 reverses to drive the rigid chain column structure 3201 to disengage, and then the camera decorative part 200 is retracted to achieve the purpose of preventing damage from falling.

[0026] Optionally, the elastic member 600 may be a spring, a spring sheet, an elastic foam, an elastic rubber or the like. Of course, the elastic member 600 may also be other structures, which is not limited herein.

[0027] In another optional embodiment, the number of the elastic member 600 and the decorative member driving mechanism 300 can be multiple, and the multiple elastic members 600 and the multiple decorative member driving mechanisms 300 can be arranged at intervals along the circumference of the camera decorative member 200. In this solution, the multiple elastic members 600 and the multiple decorative member driving mechanisms 300 are arranged at intervals along the circumference of the camera decorative member 200, so that the circumferential force of the camera decorative member 200 is relatively uniform, thereby avoiding the risk of the camera decorative member 200 being stuck in the opening 102 due to one-sided tilt, thereby improving the reliability of the lifting and lowering of the camera decorative member 200.

[0028] In the above solution, one end of the multiple chains is connected to the camera decoration 200, which means that one end of the multiple chains forming the rigid chain column structure 3201 is connected to the camera decoration 200. At this time, each chain needs to be connected to the camera decoration 200 through a corresponding connection structure, thus occupying a larger storage space 101 of the camera decoration 200 and making the assembly more complicated.

[0029] Based on this, in another optional embodiment, the decorative member driving mechanism 300 may further include a connecting seat 340, and one end of the meshed chains in the chain group 320 is connected to the connecting seat 340, and the connecting seat 340 is connected to the camera decorative member 200. In this solution, one end of the plurality of chains is fixedly connected to the connecting seat 340, and the connecting seat 340 is further connected to the camera decorative member 200. At this time, the connecting seat 340 is only fixedly connected to the camera decorative member once, and the volume of the connecting seat 340 can be set to be smaller, thereby reducing the space occupied by the camera decorative member 200 and simplifying the assembly structure.

[0030] Optionally, each chain can be connected to the connecting seat 340 by means of screws, buckles, rivets, pins and other components, and the connecting seat 340 and the camera decoration 200 can also be connected by means of screws, buckles, rivets, pins and other components.

[0031] In the above solution, during the rigid-flexible conversion process of the chain, the flexible chain structure 3202 is prone to scratch or collide with other electronic devices in the accommodation space 101, thereby causing damage to the electronic equipment.

[0032] Based on this, in another optional solution, the decoration member driving mechanism 300 may further include a chain receiving portion 350, which may be disposed in the accommodating space 101. The flexible chain structure 3202 of each chain is received in the chain receiving portion 350. In this solution, the chain receiving portion 350 can receive the flexible chain structure 3202 of each chain, thereby avoiding the risk of the flexible chain structure 3202 being scratched or collided with other electronic devices in the electronic device, thereby improving the safety performance of the electronic device.

[0033] Optionally, the chain receiving portion 350 may be provided with a guide groove 351, and the flexible chain structure 3202 of each chain is located in the guide groove 351, and the flexible chain structure 3202 of each chain can move in its corresponding guide groove 351. Alternatively, the chain receiving portion 350 is a winding shaft 353, and the flexible chain structure 3202 of each chain can be wound on its corresponding winding shaft 353. Of course, the chain receiving portion 350 can also be other structures, which are not limited herein.

[0034] In an optional embodiment, if Figure 1 As Figure 7 As shown, the chain set 320 may include a first chain 3211 and a second chain 3212, and the first chain 3211 and the second chain 3212 may each include a plurality of chain links 321a that are sequentially rotatably connected, and at least some of the chain links 321a in the first chain 3211 are correspondingly meshed with at least some of the chain links 321a in the second chain 3212. Each chain here is formed by a plurality of relatively rotating chain links 321a sequentially connected in series.

[0035] In this solution, the link 321a has a certain volume, so when a chain formed by the link 321a is used, two chains can be meshed to form a rigid chain column structure 3201, thereby making the structure of the chain set 320 simpler, thereby reducing the manufacturing cost of the electronic device.

[0036] When the chain is formed by rotating a plurality of chain links 321a in series, since the chain links 321a have a certain volume, the chain composed of the chain links 321a can be accommodated in the guide groove 351. The number of the guide grooves 351 here can be two, and the flexible chain structure 3202 of the first chain 3211 can be accommodated in one guide groove 351, and the flexible chain structure 3202 of the second chain 3212 can be accommodated in the other guide groove 351.

[0037] In another optional embodiment, the guide groove 351 has a first groove section 3511 and a second groove section 3512 arranged along its extension direction, and the flexible chain structure 3202 of the first chain 3211 can be accommodated in the first groove section 3511. The flexible chain structure 3202 of the second chain 3212 can be accommodated in the second groove section 3512. Figure 6 and Figure 7 As shown, the first groove section 3511 is the left groove section of the guide groove 351, the second groove section 3512 is the right groove section of the guide groove 351, and the position where the first chain 3211 and the second chain 3212 are engaged is the intersection of the first groove section 3511 and the second groove section 3512, which can also be understood as the middle groove section of the guide groove 351.

[0038] In this solution, the flexible chain structures 3202 of the first chain 3211 and the second chain 3212 are respectively accommodated in the groove sections on both sides of the same guide groove 351, thereby further simplifying the structure of the electronic device.

[0039] In the above solution, the chain receiving portion 350 can be a linear guide rail, and the above guide groove 351 is the guide groove of the linear guide rail. This solution has a simple structure and further reduces the manufacturing cost of the electronic device.

[0040] Furthermore, the extension direction of the linear guide rail may be perpendicular to the axial direction of the opening 102. At this time, the flexible chain structure 3202 is stored in the length direction or width direction of the electronic device, so the thickness of the electronic device can be further reduced, which is more conducive to the development of thinner and lighter electronic devices.

[0041] In an optional solution, the driving source 310 may include a driving motor 311 and a transmission gear 312, wherein the driving motor 311 is connected to the transmission gear 312, and the transmission gear 312 may be meshed with a portion of the chain links 321a of the first chain 3211 or the second chain 3212. In this solution, the driving source 310 has a simple structure and a short transmission chain, which is more conducive to improving transmission efficiency.

[0042] Of course, the driving source 310 is not limited to gear transmission, and can also be driven by a worm gear, which is not limited in this article.

[0043] Optionally, the driving motor 311 may be a DC motor or an AC motor. The transmission gear 312 may be a spur gear, or a helical gear, which is not limited herein.

[0044] The present invention discloses a specific structure of a link 321a. Of course, the link 321a can also be other structures, which are not limited in the present invention. Specifically, the link 321a can include a first chain plate 321a1, a second chain plate 321a2 and a connecting pin 321a3, and the first chain plate 321a1 and the second chain plate 321a2 are arranged opposite to each other. The connecting pin 321a3 is located between the first chain plate 321a1 and the second chain plate 321a2, and the first chain plate 321a1 and the second chain plate 321a2 can be connected by the connecting pin 321a3. The side wall of the first chain plate 321a1 can be formed with a first meshing surface 321a11, and the side wall of the second chain plate 321a2 can be formed with a second meshing surface 321a21. The two first chain plates 321a1 of the two meshing links 321a mesh with each other through the corresponding first meshing surfaces 321a11. The two second chain plates 321a2 of the two meshing links 321a can mesh with each other through the corresponding second meshing surfaces 321a21. In this solution, the structure of each link 321a is simple, and it is easy to process and manufacture. In addition, both sides of each link 321a can be meshed, so the meshing reliability is ensured while the weight of the link 321a is small.

[0045] In the above solution, the two connected links 321a can be rotatably connected by a rotating shaft, a rotating drum, etc. Of course, the two connected links 321a can also be rotatably connected by other structures, which is not limited herein.

[0046] In such Figures 1 to 7 In the scheme, the chain group 320 may include multiple first chains 3211 and multiple second chains 3212, the multiple first chains 3211 and the multiple second chains 3212 are meshed one by one, and multiple pairs of meshed rigid chain column structures 3201 are arranged in parallel to jointly support the camera decoration 200.

[0047] In another optional embodiment, if Figures 8 to 15As shown, the chain group 320 may include at least three chains, and the chain is a sheet-like structure 3213. The sheet-like structure 3213 is provided with meshing teeth 3213a on both long sides opposite to each other. At this time, a plurality of notches are provided on the edges of the long sides on both sides of each chain, and the protrusion structure between two adjacent notches is the meshing teeth 3213a. Adjacent chains can be meshed with each other through corresponding meshing teeth 3213a, and the meshing area of ​​at least three chains constitutes a ring-shaped rigid chain column structure 3201. At this time, the meshing teeth 3213a on the long side of each chain mesh with the meshing teeth 3213a on the long side of another adjacent chain. The chain moves along its length direction, thereby realizing the meshing and separation between multiple chains.

[0048] In this solution, the chain is a sheet-like structure, so the thickness of the chain is smaller, making it easier to store, thereby helping to further reduce the space occupied by the flexible chain structure 3202.

[0049] In the above solution, since the chain is a sheet-like structural member 3213, the chain group 320 needs at least three chains to form a stable rigid chain column structure 3201. Of course, the number of chains in the chain group 320 can also be four or five. Three chains can form a stable rigid chain column structure 3201, and at the same time, the number of chains is relatively small, so the number of chains is preferably three.

[0050] In the above solution, the chain receiving portion 350 may be provided with a guide groove 351, and the flexible chain structure 3202 of the sheet chain may be received in the guide groove 351. However, the sheet structure is relatively flexible, and the friction between the sheet structure and the inner wall of the guide groove 351 may easily cause the sheet structure to bend, which is not conducive to receiving the chain.

[0051] Further, the chain receiving portion 350 may include a fixed bracket 352 and at least three reeling shafts 353, and the at least three reeling shafts 353 may be rotatably connected to the fixed bracket 352. The flexible chain structure 3202 of each chain is wound on the corresponding reeling shaft 353. The driving source 310 may be connected to one of the reeling shafts 353, and the driving source 310 may drive the reeling shaft 353 to rotate, so that the length of the rigid chain column structure 3201 increases or decreases.

[0052] In a specific operation process, when the driving source 310 drives the winding shaft 353 to rotate along the first rotation direction, each winding flexible chain structure 3202 is gradually unfolded, and the area where the multiple chains are meshed gradually increases, so the length of the rigid chain column structure 3201 increases. When the driving source 310 drives the winding shaft 353 to rotate along the second rotation direction opposite to the first rotation direction, each flexible chain structure 3202 is gradually wound on the winding shaft 353, and the area where the multiple chains are meshed gradually decreases, so the length of the rigid chain column structure 3201 decreases.

[0053] In this solution, the sheet-like chain is rolled up and accommodated by the reel 353, which is more conducive to the storage of the chain. In addition, the chain is stored in a reeling manner, which can further reduce the storage volume occupied by the flexible chain structure 3202, thereby more conducive to reducing the thickness of the electronic device. At the same time, the telescopic ratio of the decorative element driving mechanism 300 is further increased.

[0054] In the above solution, the driving source 310 can be a motor, the output shaft of the motor can be connected to the winding shaft 353, and the motor can drive the winding shaft 353 to rotate.

In this case, the growth length of the rigid chain column structure 3201 is equal to the elevation distance of the camera decoration 200, so the required chain length is shorter, which helps to reduce the space occupied by the chain.

[0058] In another optional solution, the decoration member driving mechanism 300 may be disposed on the circuit board 400 . Here, it can be understood that the chain receiving portion 350 and the driving source 310 are carried on the circuit board 400 .

[0059] In this solution, the decoration driving mechanism 300 is arranged on the circuit board 400, so that the driving source 310 is conveniently electrically connected to the circuit board 400, so as to facilitate power supply to the driving source 310, thereby simplifying the circuit structure of the electronic device.

[0060] In an optional solution, the camera decoration 200 may include a decorative ring 210 and a lens 220. The lens 220 may be arranged in the inner ring area of ​​the decorative ring 210, where the lens 220 is the above-mentioned light-transmitting area. The decorative ring 210 may be located at the opening 102. The decorative ring 210 may be connected to the rigid chain column structure 3201. In this solution, the decorative ring 210 of the camera decoration 200 is connected to the rigid chain column structure 3201, thereby avoiding the risk of the rigid chain column structure 3201 affecting the light transmission of the light-transmitting area, thereby avoiding the impact on the shooting performance of the electronic device.
