Referring to fig. 1 and 2, in one embodiment, the terminal device may be a mobile phone. The terminal device includes a housing 10 and a function module 20. Wherein, the housing 10 is provided with a receiving slot 100, and the function module 20 is rotatably disposed in the receiving slot 100. The functional module 20 is mounted with a camera module 60. As shown in fig. 1 and 3, when the functional module 20 is rotated to the first position, the camera module 60 on the functional module 20 is exposed out of the housing 10, and the camera module 60 can be used for taking pictures, recording pictures, and the like. As shown in fig. 2, when the functional module 20 is rotated to the second position, the functional module 20 is just completely accommodated in the accommodating groove 100, and the camera module 60 is accommodated in the housing 10 without being visible.

As shown in fig. 4 and 5, the housing 10 includes a middle plate 11 and a rim 13 connected to at least a part of an outer edge of the middle plate 11. In one embodiment, the outer edges of the midplane 11 may each be connected to the border 13, while a hole is formed in the middle area of the midplane 11 to provide a path for electrical or physical connection of components disposed on opposite surfaces of the midplane 11. In other embodiments, the outer edge of the middle plate 11 may be partially connected to the rim 13, and the outer edge of another portion is spaced apart from the rim 13 to form a gap between the middle plate 11 and the rim 13. These gaps may also serve as pathways for electrical or physical connection of components disposed on opposite surfaces of midplane 11. Components on opposite surfaces of midplane 11 include, but are not limited to, control components (including motherboard and circuitry), power components, etc. In other embodiments, the middle plate 11 may be a block-shaped, plate-shaped, or strip-shaped structural member extending from the inner wall surface 132 of the side frame 13 toward the inside of the side frame 13, and the middle plate 11 may also be a structural member separated from the side frame 13 and connected by an intermediate member, such as an injection molding member, so that the structural member disposed in the side frame 13 and having a physical connection relationship with the side frame 13 for carrying or fixing other components is understood as the middle plate 11 in this application.

As shown in fig. 1 and 2, the terminal device further includes a display screen 30, and as shown in fig. 3, the housing 10 further includes a rear cover 15. The frame 13 has a first side 131 and a second side 133 opposite to each other. The opposite arrangement can be understood as follows: for example, in the thickness direction of the frame 13 (the Z-axis direction in fig. 1), assuming that a reference plane parallel to the XY plane is defined at a certain point position in the middle of the frame 13, it is possible to make all points on the first side surface 131 on one side of the reference plane and make all points on the second side surface 133 on the other opposite side of the reference plane. The display 30 is disposed on the side of the first side 131 of the frame 13, and the rear cover 15 is disposed on the side of the second side 133. The rear cover 15 may be integrally formed with the frame 13, and the rear cover 15 may also be fixedly connected to the frame 13 by means of gluing, welding, screwing, or the like.

The display screen 30 is used to display information. The display 30 may be a Liquid Crystal Display (LCD) 30 or an Organic Light-Emitting Diode (OLED) display 30. In an embodiment, the display screen 30 is a touch display screen, and the user can perform a touch operation on the information displayed on the display screen 30 by a touch operation mode. In other embodiments, the display screen 30 may also be a non-touch display screen, and is only used for displaying information.

Since the functional module 20 carrying the camera module 60 is disposed in the receiving groove 100 of the housing 10, the area of the first side 131 of the housing 10 where the display 30 is located is not occupied, and therefore, the screen occupation ratio of the terminal device, that is, the area occupation ratio of the display 30 on the first side 131 can be increased.

As shown in fig. 1 to 3, the opening of the receiving slot 100 is located between the first side 131 and the second side 133 of the frame 13. In this case, the housing groove 100 is located in the middle region in the thickness direction of the bezel 13 and does not penetrate the first side surface 131 or the second side surface 133. In other embodiments, the opening position of the receiving slot 100 may be changed, for example, the opening position may directly penetrate through the second side 133 of the frame 13, or penetrate through the rear cover 15 on the side where the second side 133 is located. At this time, the receiving groove 100 has an open structure, that is, the receiving groove 100 has an opening in the direction of the outer peripheral surface 134 of the frame 13, and also has an opening in the direction of the second side surface 133 of the frame 13. In this case, the housing groove 100 is considered to be formed by the second side surface 133 of the housing 10 being recessed toward the first side surface 131, and the housing groove 100 communicates with the outside in the direction of the second side surface 133 of the frame 13 and communicates with the outside in the direction of the outer peripheral surface 134 of the frame 13.

As shown in fig. 4, rear cover 15 on bezel 13 is hidden to expose a second side 133 of bezel 13 and the perspective of middle plate 11 within bezel 13. Retaining walls 17 are also connected to the frame 13. The retaining wall 17 defines at least a portion of the boundary of the receiving slot 100 inside the housing 10. The retaining wall 17 extends inside the frame 13 to form a major arc shape, and both ends of the retaining wall 17 in the extending direction are connected to the inner wall surface 132 of the frame 13. The retaining wall 17 shown in fig. 4 is also connected to the middle plate 11 at the same time on the side close to the first side 131 of the frame 13. In other embodiments, the retaining wall 17 with a curved shape may be connected to the middle plate 11 only, and the two ends may form a gap with the frame 13. In addition, the retaining wall 17 in fig. 4 is continuously extended to form a major arc shape, but it is understood that the retaining wall 17 may be a plurality of separated segments in other embodiments, and may also define at least a partial boundary of the receiving groove 100 inside the housing 10.

As shown in fig. 4, when the functional module 20 is accommodated in the accommodating cavity 100, the functional module 20 can be observed after the rear cover 15 is removed. In other embodiments, a protective cover may be further disposed on a side of the retaining wall 17 close to the second side 133 of the frame 13 for shielding the functional module 20. At this time, even in the viewing angle as in fig. 4 after the rear cover 15 is removed, the function module 20 cannot be observed. The protective cover may be located under the rear cover 15 to be shielded by the rear plate. The protective cover may also be located at the same level as the rear cover 15, and a notch is formed in the rear cover 15 to accommodate the protective cover, that is, the protective cover and the rear cover 15 are combined to be used as a rear shell of the terminal device.

As shown in fig. 5, the display screen 30 is hidden to expose the viewing angle of the first side 131 of the bezel 13. It can be seen that a plurality of fixing holes 110 are provided on the middle plate 11, and the relevant components in the functional module 20 can be fastened to the middle plate 11 by fastening members passing through the fixing holes 110.

As shown in fig. 6 and 7, the function module 20 includes a driving mechanism 40, a gear transmission mechanism 50, and the camera module 60. The driving mechanism 40 is fixedly connected to the housing 10, outputs power, and enables the camera module 60 to rotate to enter and exit the receiving slot 100 by the transmission of the gear transmission mechanism 50.

Referring to fig. 8 and 9, the driving mechanism 40 includes a bracket 41 and a driving element 47, the driving element 47 is fixedly connected to the housing 10 through the bracket 41, specifically, a fastening hole 400 adapted to the fixing hole 110 of the middle plate 11 is disposed at a corresponding position on the bracket 41, and a fastening member passes through the fixing hole 110 of the middle plate 11 from the side where the first side surface 131 of the side frame 13 is located and is then fastened in the fastening hole 400 of the bracket 41, so that the bracket 41 can be fastened to the housing 10, and the driving element 47 is further fixed to the housing 10. In this embodiment, the bracket 41 is separated from the housing 10, and the bracket 41, the driving member 47, the gear mechanism 50 and the camera module 60 can be assembled together to form a module, and then the module can be assembled with other components of the terminal device to form a complete terminal device. The design mode can lead the industry to have more detailed division and higher production efficiency, for example, the module formed by the bracket 41, the driving piece 47, the gear transmission mechanism 50 and the camera module 60 can be independently supplied by an upstream manufacturer and delivered to a downstream manufacturer to complete the final assembly. In addition, because of above-mentioned module can with the split of casing 10, also be convenient for terminal equipment's maintenance, reduce consumer's use cost. For example, when a corresponding component on the module of the terminal device fails, the module can be replaced without having to discard the entire terminal device.

In other embodiments, a portion of the bracket 41 may be integrally formed with the housing 10, as will be further described below when describing the specific components of the bracket 41.

As shown in fig. 8 and 9, the bracket 41 includes a mounting plate 42, an inner side plate 43 and a top plate 44, the inner side plate 43 is connected between the top plate 44 and the mounting plate 42, the mounting plate 42 is fixedly connected to the housing 10, and the inner side plate 43 and the top plate 44 enclose a first accommodating space 430 for accommodating the driving member 47. Specifically, the mounting plate 42 may be fixed to the middle plate 11. The fastening hole 400 may be formed in the mounting plate 42. In this embodiment, the inner plate 43, the top plate 44, and the mounting plate 42 are integrally molded. In another embodiment, the inner side plate 43 and the top plate 44 may be integrally formed and disposed separately from the mounting plate 42, and the integrally formed inner side plate 43 and the top plate 44 are connected to the mounting plate 42 by other means such as gluing. At this time, the mounting plate 42 may be a part of the middle plate 11, that is, the mounting plate 42 may be integrally formed with the housing 10.

In one embodiment, as shown in fig. 8 and 9, the bracket 41 further includes an outer plate 45 disposed on the mounting plate 42, and a second accommodating space 450 is formed between the outer plate 45 and the inner plate 43. The open end of the first accommodating space 430 faces opposite to the open end of the second accommodating space 450. When the function module 20 is installed in the receiving slot 100, the open end of the first receiving space 430 faces to a side of the first side surface 131 of the frame 13, and the open end of the second receiving space 450 faces to a side of the second side surface 133 of the frame 13. The second accommodating space 450 is used for accommodating a flexible circuit board, which is used for connecting the camera module 60 and a main board of a terminal device.

The periphery of the inner side plate 43 and the corresponding position of the camera module 60 are provided with a snap structure 420, and the camera module 60 is rotatably connected with the bracket 41 by means of the snap structure 420, so that the camera module 60 can rotate relative to the housing 10 under the driving of the driving member 47 to enter and exit the accommodating groove 100. Specifically, an annular groove 421 is provided on the outer periphery of the inner plate 43, and an annular rib 422 matching with the annular groove 421 is provided on the camera module 60, so that the camera module 60 can rotate around the inner plate 43 of the bracket 41. It is understood that the positions of the annular groove 421 and the annular protrusion 422 are also reversed, that is, the annular protrusion 422 is disposed on the outer periphery of the inner plate 43, and the annular groove 421 is disposed on the camera module 60. Considering the assembly feasibility and the service life of the bracket 41 and the camera module 60, the bracket 41 and the part of the camera module 60 where the snap structure 420 is formed can be made of materials with different hardness, so that the snap structure 420 can be more easily installed. In addition, the sizes of the annular groove 421 and the annular protrusion 422 should be different to satisfy that the relative rotation between the camera module 60 and the bracket 41 is not limited.

As shown in fig. 7 and 8, in one embodiment, the camera module 60 includes a rotating member 61 and a camera 67 disposed on the rotating member 61. The rotating member 61 is rotatably connected with the bracket 41 through the snap structure 420. Specifically, the rotating member 61 is sleeved on the bracket 41, the inner wall surface 612 of the rotating member 61 and the outer periphery of the bracket 41 are provided with the mutually-matched snap structures 420, for example, the inner wall surface 612 of the rotating member 61 is provided with the annular convex strip 422, and the outer periphery of the inner side plate 43 of the bracket 41 is provided with the annular concave groove 421.

The drive member 47 may be a motor. The driving member 47 has a driving shaft 471, the driving member 47 is installed in the first accommodating space 430 of the bracket 41, and the driving shaft 471 penetrates through the top plate 44. The driving shaft 471 of the driving member 47 coincides with the rotation axis center of the rotating member 61. The above-mentioned arrangement relationship among the driving element 47, the rotating element 61 and the bracket 41 can make full use of the inner space of the bracket 41 for placing the driving element 47, and also make full use of the inner space of the rotating element 61 for placing the bracket 41, so that the spaces occupied by the driving element 47 and the rotating element 61 are overlapped around the rotating shaft as much as possible, thereby reducing the size in the radial direction. Meanwhile, the rotating member 61, the bracket 41 and the driving member 47 are also arranged in an overlapping manner in the extending direction of the rotating shaft, and the size in the axial direction is also reduced.

The gear transmission mechanism 50 is carried on the bracket 41 and is in transmission connection with a drive shaft 471 that extends through the top plate 44. The gear transmission mechanism 50 is disposed between the rotary member 61 and the holder 41, and drivingly connects the drive shaft 471 and the rotary member 61. Specifically, the gear transmission mechanism 50 is located between the bottom end surface 610 of the rotary member 61 and the top end surface 410 of the holder 41, and is restricted by the rotary member 61 and the holder 41 in the axial direction, so that the runout in the axial direction is controlled. The inner wall surface 612 of the rotating member 61 forms a transmission tooth 611 engaged with the gear transmission mechanism 50, and the driving shaft 471 of the driving member 47 penetrates through the bracket 41 and is exposed to the top end surface 410 of the bracket 41 to engage with the gear transmission mechanism 50.

In an embodiment, the gear transmission mechanism 50 includes a main gear 501 and planetary gears 502, the main gear 501 is linked with the driving shaft 471, and the planetary gears 502 surround the outer circumference of the main gear 501 and are meshed with the main gear 501. The gear teeth 611 surround the outer circumference of the planetary gear 502 and mesh with the planetary gear 502.

As shown in fig. 8, 9 and 10, a baffle 46 is further disposed on the top end surface 410 of the bracket 41, and the baffle 46 defines the range of motion of the gear transmission mechanism 50. The stopper 46 restricts the movement space of the gear transmission mechanism 50 in the radial direction, preventing displacement in the radial direction. Specifically, the baffle 46 is disposed on the top plate 44, and the height of the baffle 46 is smaller than the axial length of the gear transmission mechanism 50, so that the gear transmission mechanism 50 is still partially exposed in the axial direction to engage with the transmission teeth 611 of the rotating member 61.

Further, the inner surface of the baffle 46 forms a fixed tooth 461 engaged with the gear transmission mechanism 50, that is, the fixed tooth 461 and the transmission tooth 611 are simultaneously engaged with the gear transmission mechanism 50, and the fixed tooth 461 of the baffle 46 and the transmission tooth 611 on the rotating member 61 are located on the same vertical circumferential surface. Since the carrier 41 is fixed, when the driving member 47 drives the main gear 501 to rotate, the planetary gears 502 not only have the revolving speed around the main gear 501, but also have the rotating speed engaged with the static teeth 461 of the blocking plate 46, that is, the rotating member 61 driven by the planetary gears 502 also has the revolving and rotating speeds of the planetary gears 502, which can improve the transmission ratio.

The outer circumference of the baffle 46 is flush with the outer circumference of the inner side plate 43, in other words, the baffle 46 can be seen as a further extension of the inner side plate 43. The snap structure 420 for rotatably connecting the rotary member 61 and the bracket 41 may also be formed on the outer circumferential surface of the blocking plate 46.

Referring to fig. 8, 11 and 12 together, the rotary member 61 includes a sleeve 62 and a carrier plate 63 disposed at an outer circumference of the sleeve 62. The sleeve 62 is sleeved on the driving mechanism 40 and the gear transmission mechanism 50. The sleeve 62 is also fitted over the bracket 41. The drive teeth 611 are disposed on an inner wall surface 612 of the sleeve 62. A snap structure 420 that rotatably connects the rotary member 61 with the holder 41 is also formed on the inner wall surface 612 of the sleeve 62.

The camera 67 is mounted on the carrier plate 63. The bearing plate 63 is provided with a through hole 630 exposing the light incident surface of the camera 67. Further, as shown in fig. 7 and 8, the rotating member 61 further includes a protective lens 64, and the protective lens 64 is mounted on the bearing plate 63 and covers the through hole 630. In some embodiments, the camera module 60 further includes at least one of a light sensor, a flashlight, an iris recognition module, a face recognition module, a proximity sensor, an ambient light sensor, a microphone, and a receiver, which are disposed on the rotating member 61, and these elements may also be mounted on the bearing plate 63. When the elements need channels for lighting or sound collection, through holes 630 matching with the elements in number can be correspondingly formed on the bearing plate 63.

Referring to fig. 8, 11 and 12 together, the rotary member 61 further includes a peripheral plate 65 provided at an edge of the carrier plate 63. As shown in fig. 2, when the camera 67 is located in the receiving slot 100, at least a part of the contour of the peripheral plate 65 forms a smooth engagement with the contour of the housing 10, so that the integrity of the appearance of the terminal device is not damaged. In one embodiment, the contour of the peripheral plate 65 is the same as the shape of the outer peripheral surface 134 of the frame 13 at the opening position of the receiving slot 100, and may be a plane or an arc surface. At the same time, the contour of at least another portion of the peripheral plate 65 matches the contour of the housing groove 100, so that it can be smoothly turned into the housing groove 100. In one embodiment, another portion of peripheral plate 65 is contoured in a major arc.

Further, as shown in fig. 7 and 8, the rotating member 61 further includes a cover plate 66 connected to the peripheral plate 65, and the camera 67 is accommodated in an area surrounded by the sleeve 62, the carrier plate 63, the peripheral plate 65, and the cover plate 66.

In the above embodiment, the through hole 630 is opened on the bearing plate 63 to expose the light incident surface of the camera 67, so that the camera 67 is used as the front camera 67, as shown in fig. 1, the light incident surface of the camera 67 is located on the same side as the display screen 30 of the terminal device. It is understood that in some embodiments, camera module 60 may also include a rear camera 68. Fig. 13 shows the rear view angle of the terminal device in an embodiment, in which the light incident surface of the rear camera 68 is on the same side as the rear cover 15 of the terminal device. The rear camera 68 can still be mounted on the carrier plate 63, but the light incident surface of the rear camera 68 faces the cover plate 66, and another through hole 630 exposing the light incident surface of the rear camera 68 is opened on the cover plate 66.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
