Description

Technical Field

[0001] The present disclosure relates to the technical field of terminals, and in particular, to a camera structure and a terminal device. Background Art

[0002] With the development of the times, the camera function has gradually become one of the essential important functions of terminal devices such as mobile phones and tablet computers. In the early stage, terminal devices with a camera function only had a single rear camera module. During the selfie process, users could not adjust their expressions and posing postures by observing the image on the screen of the terminal device in real time, which seriously affected the user experience.

[0003] To solve this problem, a front camera module came into being. When users use the front camera to take pictures, they can observe the image on the screen during the shooting process and adjust their expressions and posing postures at any time to obtain more satisfactory selfies, thus enhancing the user experience.

[0004] With the continuous development of technology, in order to enhance the user experience, various electronic product manufacturers have introduced the design concept of full-screen. Narrowing the area of the front camera module to increase the screen-to-body ratio and further achieve the effect of a full-screen has gradually become the mainstream design direction of terminal devices such as mobile phones. The mainstream design directions for narrowing the front camera module include notch screens, waterdrop screens, or hole-drilled screens (single-hole or double-hole), etc. In particular, hole-drilled screens are favored by various mobile phone manufacturers.

[0005] However, narrowing the front camera module still cannot achieve a true full-screen. Summary of the Invention

[0040] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with the present invention. On the contrary, they are only examples of the devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0041] In the related art, in order to implement the concept of a full-screen for terminal devices, major electronic product manufacturers have proposed to design the front camera into a pop-up and hidden structure, which pops out to the outside of the terminal device only when the user needs to take a selfie, ensuring the integrity of the screen and realizing the full-screen design of the terminal device.

[0042] However, the front camera and the rear camera of the pop-up and hidden structure are separately arranged, increasing the production cost and the structure is complex. Multiple openings are made to correspond to the installation of the front camera and the rear camera, affecting the appearance of the terminal device and reducing the aesthetic degree of the terminal device. The independent design of the front camera and the rear camera occupies a large internal space, which is not conducive to the thinning process of the terminal device, affects the user's feeling of holding the terminal device, and reduces the user's experience.

[0043] The present disclosure provides a camera structure disposed in a terminal device, which can be, for example, a mobile phone, a tablet computer, etc. The camera structure includes a telescopic camera module and a rotation driving component. The telescopic camera module is driven by the rotation driving component to achieve the switching of the camera structure modes, meeting the needs of users. Among them, the rotation driving component includes a torque output unit and a torque transmission part. The torque transmission part is respectively connected to the telescopic camera module and the torque output unit. When the telescopic camera module extends out of the terminal device, the torque output unit outputs torque to the torque transmission part, and the torque transmission part drives the telescopic camera module to rotate between a first position and a second position by self-rotation, so as to switch between the front camera mode and the rear camera mode, ensuring the shooting quality. At the same time, the front camera mode and the rear camera mode share the camera module, reducing the occupied space and saving costs.

[0044] In an exemplary embodiment, as Figures 1-7 shown, the camera structure is disposed in a terminal device, which can be, for example, a mobile phone, a tablet computer, a laptop computer, a wearable device, etc. The terminal device includes, for example, a middle frame 4, and the camera structure is installed on the middle frame 4. A channel 41 communicating the inside and the outside of the terminal is opened on the side of the middle frame 4, enabling the camera 11 to move along the channel 41, so as to achieve the pop-up effect of the camera structure of the terminal device, thereby protecting the camera structure and reducing the wear rate of the camera structure.

[0045] In this embodiment, still referring to Figures 1-7 shown, the camera structure includes a telescopic camera module 1 and a rotation driving component 2. The telescopic camera module 1 realizes rotation through the rotation driving component 2, completing the switching between shooting modes. The structure is simple, occupies a small space, and saves costs.

[0046] Among them, the rotation driving component 2 includes a torque output unit 21 and a torque transmission part 22. The torque transmission part 22 is respectively connected to the telescopic camera module 1 and the torque output unit 21.

[0047] When the telescopic camera module 1 extends out of the terminal device, the torque output unit 21 outputs torque to the torque transmission part 22, and the torque transmission part 22 drives the telescopic camera module 1 to rotate between a first position and a second position by self-rotation, so as to complete the switching between the front camera mode and the rear camera mode of the terminal device, realizing the conversion of the shooting mode of the terminal device, reducing the occupied space of the camera structure, optimizing the internal space layout of the terminal device, and facilitating the thinning process of the terminal device. Among them, the first position can be, for example, one side of the back of the terminal device body, and the second position can be, for example, one side of the display screen of the terminal device.

[0048] In an example, referring to Figure 2As shown, the torque output unit 21 is, for example, a driving motor, and the torque transmission part 22 is, for example, a torque transmission rod structure. The output shaft of the driving motor is fixedly connected to the torque transmission rod, and the torque transmission rod is fixedly connected to the telescopic camera module 1, so that the torque output unit 21 can directly control the telescopic camera module 1 to realize the rotation of the telescopic camera module 1. When the user needs to use the front camera mode, the driving motor operates and outputs torque to drive the torque transmission rod structure to rotate along its axial direction, thereby driving the telescopic camera module 1 to rotate from the first position to the second position, and switching the rear camera mode of the terminal device to the front camera mode.

[0049] In another example, referring to Figure 1 、 Figure 4 As shown, the torque output unit 21 may also include a first transmission part and a second transmission part, the first transmission part is meshed and connected with the second transmission part, and the second transmission part is fixedly connected to the torque transmission part 22. The first transmission part moves under the action of an external force, drives the second transmission part to rotate, and then drives the torque transmission part 22 to rotate.

[0050] Among them, the first transmission part includes a rack 211, the second transmission part includes a gear 212, and the rack 211 and the gear 212 are meshed with each other. Under the action of an external force, the rack 211 makes a linear motion along its extending direction (referring to the X-axis direction as shown in Figure 1 ), so that the gear 212 rotates synchronously. And the torque transmission part 22 is fixedly passed through the middle of the gear 212, and the gear 212 drives the torque transmission part 22 to rotate, so that the telescopic camera module 1 realizes the rotation between the first position and the second position through the torque transmission part 22.

[0051] In an exemplary embodiment, as Figures 1-7 shown, the rotation driving assembly 2 further includes a limiting assembly 23, and the limiting assembly 23 is arranged on the extension line of the rack 211. Under the action of an external force, when the rack 211 moves to the limit position along its extending direction, the end of one end of the rack 211 is in abutting connection with the limiting assembly 23.

[0052] Among them, the limit position of the rack 211 corresponds to the second position of the telescopic camera module 1, that is, the front camera mode of the terminal device. Of course, the initial movement position of the rack 211 can be understood as the first position of the telescopic camera module 1, that is, the rear camera mode of the terminal device.

[0053] In this embodiment, referring to Figure 1 、 Figures 4-7As shown, the limiting component 23 includes a limiting elastic element 231, and the limiting elastic element 231 is, for example, a limiting spring. The limiting component 23 further includes a limiting portion 232, and the limiting portion 232 is, for example, a limiting cylinder. The limiting cylinder can be directly formed on the mounting bracket 11, or can be fixedly connected to the mounting bracket 11 through a connecting plate body 233. The limiting elastic element 231 is sleeved on the limiting portion 232 and is connected to the rack 211. For example, a blind hole 2111 is formed at one end of the rack 211, the first end of the limiting elastic element 231 is fixedly installed in the blind hole 2111, and the second end of the limiting elastic element 231 is sleeved on the limiting portion 232. The limiting elastic element 231 restricts the movement direction of the rack 211, so that the rack 211 can perform a linear motion along its extending direction (refer to the X-axis direction as shown in Figure 7 ), ensuring the normal rotation of the telescopic camera module 1 and preventing the rack 211 from shifting during movement and causing damage to the telescopic camera module 1.

[0054] In an exemplary embodiment, as shown in Figures 1-7 , the rotation driving component 2 further includes a mounting portion 24, the rack 211 is formed on the mounting portion 24, and a driving guide groove 241 is further provided on the mounting portion 24. Among them, the driving guide groove 241 is, for example, an inclined groove, and the driving guide groove 241 is correspondingly arranged on one side of the mounting portion 24 away from the blind hole 2111 of the rack 211. The driving guide groove 241 extends along a first direction (refer to the A-axis direction as shown in Figure 7 ), and the first direction forms a predetermined angle with the movement direction of the rack 211 (refer to the X-axis direction as shown in Figure 7 ). Among them, the predetermined angle can be, for example, 120° - 150°.

[0055] Among them, referring to Figures 6-7 shown, the driving guide groove 241 is provided with a driving portion 311. Under the action of an external force, the driving portion 311 applies a driving force to the mounting portion 24 through the driving guide groove 241 to drive the rack 211 to move.

[0056] In this embodiment, referring to Figure 1 、 Figure 4 、 Figure 7As shown, a limiting track groove 242 is further formed on the mounting part 24. The limiting track groove 242 penetrates through the mounting part 24, and the extending direction of the limiting track groove 242 is the same as that of the rack 211. A positioning member 116 is arranged in the limiting track groove 242, and the positioning member 116 is fixedly mounted on the mounting bracket 11. The limiting track groove 242 and the positioning member 116 are in fit connection. The positioning member 116 is, for example, two pin shafts. The two pin shafts extend into the limiting track groove 242. The two pin shafts are arranged separately along the extending direction of the limiting track groove 242 and have a certain distance. Among them, the two pin shafts can be, for example, correspondingly arranged at the end of the limiting track groove 242, or can also be arranged at a position close to the end of the limiting track groove 242, so that the positioning member 116 and the limiting track groove 242 can achieve the purpose of mutual restriction, and further limit the movement direction of the mounting part 24.

[0057] When the driving part 311 applies a driving force to the mounting part 24 through the driving guide groove 241, the limiting track groove 242 on the mounting part 24 is restricted by the positioning member 116. When the mounting part 24 moves, a relative displacement occurs between the limiting track groove 242 thereon and the positioning member 116, so that the mounting part 24 can only move along the extending direction of the rack 211, ensuring the normal rotation of the telescopic camera module 1.

[0058] Here, it should be noted that the limiting track groove can also be formed on the mounting bracket, the positioning member is fixedly mounted on the mounting part, and the positioning member is in fit connection with the limiting track groove, which can also play a role in limiting the mounting part. The installation positions of the above-mentioned limiting track groove and the positioning member are only used to explain this embodiment and do not constitute a limitation to this application. The installation positions of the limiting track groove and the positioning member can be defined according to the layout inside the terminal device.

[0059] In an exemplary embodiment, as Figures 1-7 shown, the telescopic camera module 1 includes a mounting bracket 11 and a camera 12. The camera 12 is mounted on the mounting bracket 11 through a torque transmission part 22. The mounting bracket 11 includes, for example, a first mounting plate 112, a bracket body 111, and a second mounting plate 113 that are fixedly connected in sequence. The first mounting plate 112 and the second mounting plate 113 are respectively perpendicular to the bracket body 111.

[0060] Among them, the first mounting plate 112 is provided with a mounting through hole 1121. The first end of the torque transmission part 22 rotates through the mounting through hole 1121 and is fixedly connected to the camera 12. The second end of the torque transmission part 22 fixedly passes through the gear 212 and is rotatably connected to the second mounting plate 113. By limiting the torque transmission part 22 through the first mounting plate 112 and the second mounting plate 113 at the same time, the meshing effect between the gear 212 and the rack 211 is ensured, and it is ensured that the gear 212 can rotate along its axis direction.

[0061] In this embodiment, referring to Figure 4 , Figure 5 As shown, a support portion 114 is provided on the mounting bracket 11. The support portion 114 is, for example, a columnar structure. The support portion 114 is arranged in parallel with the torque transmission portion 22. Both ends of the support portion 114 are fixedly connected to the first mounting plate 112 and the second mounting plate 113 of the mounting bracket 11 respectively. A driving elastic element 115 is sleeved on the support portion 114. The driving elastic element 115 is, for example, a compression spring. The fixed end of the driving elastic element 115 is fixedly connected to the first mounting plate 112.

[0062] Among them, referring to Figure 1 , Figure 4 , Figure 6 As shown, the camera structure further includes a telescopic driving assembly 3. The telescopic driving assembly 3 includes a driving link 31. The driving link 31 is, for example, a plate-like structure. A first through hole 313 is provided at one end of the driving link 31. The driving link 31 is movably sleeved on the support portion 114 through the first through hole 313. The free end of the driving elastic element 115 is in contact connection with the driving link 31 sleeved on the support portion 114. Under the action of an external force, the driving link 31 can move along the extension direction of the support portion 114 (referring to the A-axis direction shown in Figure 1 ) and compress the driving elastic element 115.

[0063] In this embodiment, referring to Figure 1 , Figure 4 , Figure 6 , Figure 7 As shown, a driving portion 311 is provided on the driving link 31. The driving link 31 is, for example, bent at an edge close to the camera 12 to form a connecting portion 312. The connecting portion 312 is arranged perpendicular to the driving link 31. The driving portion 311 is formed on the connecting portion 312 and extends along the thickness direction of the connecting portion 312. The driving portion 311 and the driving link 31 are respectively arranged on both sides of the connecting portion 312. Among them, the driving portion 311 can be, for example, a columnar structure or a spherical structure. When the driving portion 311 extends into the driving guide groove 241, the driving portion 311 can slide smoothly in the driving guide groove 241.

[0064] When the telescopic camera module 1 rotates between the first position and the second position, the driving link 31 compresses the driving elastic element 115, and the driving portion 311 slides along the driving guide groove 241 to apply a driving force to the mounting portion 24, driving the rack 211 to move along the extension direction (referring to the X-axis direction shown in Figure 1 ), thereby completing the rotation of the telescopic camera module 1 until the telescopic camera module 1 rotates 180°, realizing the front camera mode of the terminal device.

[0065] In an exemplary embodiment, as Figures 1-7As shown, the telescopic driving assembly 3 further includes a power output device 32 for applying a driving force to the driving link 31.

[0066] In one example, referring to Figure 3 As shown, the power output device 32 is, for example, a micro cylinder. The piston end of the power output device 32 is fixedly connected to the driving link 31. The power output device 32 drives the driving link 31 to perform a linear motion along the extension direction of the support portion 114 (referring to the Y-axis direction shown in Figure 3 ). The driving link 31 pushes the free end of the driving elastic element 115, causing it to drive the mounting bracket 11 to move, and moving the camera 12 from the inside of the terminal device to the outside of the terminal device, achieving the pop-up effect of the camera 2.

[0067] When the first mounting plate 112 forms an abutting connection with the middle frame 4 of the terminal device, the mounting bracket 11 stops moving. The camera 12 moves to the outside of the terminal device through the channel 41 on the middle frame 4, making the telescopic camera module 1 in a pop-up state, realizing the rear camera mode of the camera structure, so that the user can use the rear camera mode to take pictures of scenery, things, or people, etc.

[0068] When the user wants to use the front camera mode of the terminal device, the power output device 32 continues to operate, compressing the driving elastic element 115, so that the driving link 31 can continue to move. The driving link 31 drives the driving portion 311 to move, so that the driving portion 311 can apply a driving force to the driving guide groove 241 to push the mounting portion 24 to move, completing the conversion from the rear camera mode to the front camera mode.

[0069] In another example, referring to Figure 1 、 Figure 4 、 Figure 6 As shown, the power output device 32 is, for example, a driving motor. The telescopic driving assembly 3 further includes a screw rod 33, which is arranged parallel to the support portion 114. The output end of the power output device 32 is fixedly connected to the first end of the screw rod 33. Wherein, the other end of the driving link 31 is provided with a second through hole 314, and the driving link 31 is sleeved on the screw rod 33 through the second through hole 314 and is threadedly connected to the screw rod 33.

[0070] When the power output device 32 operates, the drive shaft of the power output device 32 drives the screw rod 33 to rotate along its axis, causing the driving link 31 to move along the extension direction of the screw rod 33 (referring to the Y-axis direction shown in Figure 1 ). The driving link 31 pushes the free end of the driving elastic element 115, causing it to drive the mounting bracket 11 to move, and moving the camera 12 from the inside of the terminal device to the outside of the terminal device, achieving the pop-up effect of the camera 2.

[0071] Here, it should be noted that the elastic coefficient of the above-mentioned driving elastic element is adjusted according to actual needs. During the process of the telescopic camera module switching to the pop-up state, it is defined that the thrust of the driving link is always less than the force of the driving elastic element being compressed, ensuring that the driving elastic element can maintain its natural state during this process. This ensures the normal switching of the normal mode of the telescopic camera module and avoids scratching the camera of the telescopic camera module. When the camera of the telescopic camera module completely pops out to the outside of the terminal device, the driving elastic element can be compressed by the driving link.

[0072] In an exemplary embodiment, as Figures 1-7 shown, the telescopic driving assembly 3 further includes a driving bracket 34, and the driving bracket 34 is fixedly installed in the terminal device. The driving bracket 34 includes, for example, a first bracket plate 341 and a second bracket plate 342, and the first bracket plate 341 and the second bracket plate 342 are arranged opposite to each other. A connecting ear 3411 is formed by bending the edge of the first bracket plate 341, and the first bracket plate 341 is fixed to the middle frame 4 of the terminal device through the connecting ear 3411. The connecting ear 3411 can be bonded to the middle frame 4 or fixed to the middle frame 4 by screws. The way the second bracket plate 342 is fixed to the middle frame 4 is the same as the way the first bracket plate 341 is fixed to the middle frame 4, and will not be repeated here.

[0073] Among them, the power output device 32 and the screw 33 are both installed on the driving bracket 34.

[0074] When the power output device 32 is, for example, a driving motor, the housing of the driving motor is fixedly connected to the second bracket plate 342, and the driving shaft of the driving motor rotates through the second bracket plate 342. The screw 33 is arranged between the first bracket plate 341 and the second bracket plate 342, the driving shaft of the driving motor is fixedly connected to the first end of the screw 33, and the second end of the screw 33 is rotatably connected to the first bracket plate 341.

[0075] When the power output device 32 is, for example, a micro cylinder, the cylinder body of the micro cylinder is fixedly connected to the second bracket plate 342, and the piston rod of the micro cylinder passes through the second bracket plate 342 and is fixedly connected to the driving link 31.

[0076] In this embodiment, still referring to Figures 1-7 shown, the telescopic driving assembly 3 further includes a guide rod 35. The guide rod 35 is a rod-shaped structure and is parallel to the screw 33. The guide rod 35 is arranged between the first bracket plate 341 and the second bracket plate 342, and both ends of the guide rod 35 are fixedly connected to the first bracket plate 341 and the second bracket plate 342 respectively. A third through hole 315 is formed on the driving link 31, and the guide rod 35 passes through the driving link 31 through the third through hole 315, playing a role in limiting the driving link 31, so that the driving link 31 can extend along the extension direction of the guide rod 35 (refer toFigure 1 movement in the Y-axis direction (as shown).

[0077] Moreover, to further improve the stability of the movement of the telescopic camera module 1, when the power output device 32 is, for example, a driving motor, the guide rod 35 can be arranged between the screw rod 33 and the support portion 114 to balance the camera structure. When the power output device 32 is, for example, a micro cylinder, the screw rod 33 can be arranged between the guide rod 35 and the support portion 114 to ensure the stability during driving.

[0078] The present disclosure also provides a terminal device, which can be a mobile phone, a tablet computer, a notebook computer, a wearable device, etc. The terminal device includes a middle frame and the above-mentioned camera structure.

[0079] Among them, the camera structure is installed on the middle frame, and a channel communicating the inside and outside of the terminal device is provided on the side of the middle frame, so that the telescopic camera module of the camera structure can complete the pop-up or retraction action through the channel.

[0080] Adopting the above-mentioned camera structure can ensure the integrity of the body appearance of the terminal device and realize the full-screen design concept of the terminal device. Moreover, the terminal device shares a camera structure, and the telescopic camera module of the camera structure rotates between the first position and the second position in a self-rotation manner to complete the conversion between the front camera mode and the rear camera mode, saving the overall manufacturing cost of the terminal device, reducing the internal space occupied by the terminal device, optimizing the internal space layout of the terminal device, and facilitating the thinning process.

[0081] After the user inputs a control instruction to the terminal device to use the rear camera mode for shooting, the power output device drives the screw rod to rotate to drive the driving link to move along the extension direction of the screw rod. The driving link pushes the driving elastic element to move, and the driving elastic element drives the mounting bracket to move, so that the camera extends out of the terminal device through the channel of the middle frame, realizing the rear camera mode of the terminal device, and the user uses the rear camera mode to shoot scenery or people, etc.

[0082] After the user inputs a control instruction to the terminal device to use the front camera mode for shooting, the power output device continues to drive the screw rod to rotate. The driving elastic element is compressed, so that the driving link can continue to move along the extension direction of the screw rod. The driving portion on the driving link applies a driving force to the mounting portion through the driving guide groove, and the mounting portion drives the rack to move along its extension direction, so that the gear drives the torque transmission portion to rotate, and the camera is driven by the torque transmission portion to rotate 180°, completing the switching from the rear camera mode to the front camera mode, and improving the user experience.

[0083] After the user finishes shooting, the user inputs an operation instruction to retract the telescopic camera module into the terminal device. The power output device rotates in the reverse direction, driving the screw to rotate in the reverse direction. The driving link moves along the extension direction of the screw, causing the driving elastic element to be in a released state, and the camera rotates 180°, so as to realize the conversion from the front camera mode to the rear camera mode. The power output device continues to operate to drive the telescopic camera module to be in a retracted state. The telescopic camera module is completely placed inside the terminal device, which not only enhances the aesthetics of the terminal device, but also protects the telescopic camera module from being exposed outside the terminal device and causing damage to the telescopic camera module.

[0084] Those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include known common knowledge or conventional technical means in the technical field not disclosed in this disclosure.
