[ detailed description ] embodiments

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.

The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1 and 2, the electronic device includes a smart phone, a tablet, a notebook, a smart watch, a PDA, and the like, which are not limited herein. The electronic device comprises a display screen assembly 10, a lifting shell 20, a fixed shell 30, a camera module 40 and a power mechanism 50, wherein the display screen assembly 10 is fixed on the fixed shell 30, the camera module 40 is arranged in the lifting shell 20, the lifting shell 20 is slidably connected with the fixed shell 30, and the power mechanism 50 is used for enabling the lifting shell 20 to slide relative to the fixed shell 30, so that the camera module 40 can be switched between two states that the camera module is not shielded by the fixed shell 30 or is shielded by the fixed shell 30 in the sliding process of the lifting shell 20 relative to the fixed shell 30. The fixed housing 30 is used for accommodating components such as a battery, a main board, a processor, a speaker, a microphone, and the like.

In a non-extended state, the camera module 40 is blocked by the fixed housing 30 and cannot receive external ambient light, and at this time, the projection of the camera module 40 on the plane where the display screen assembly 10 is located at least partially overlaps with the display area 112 of the display screen assembly 10; in the extended state, the camera module 40 is not blocked by the fixed housing 30, and can normally receive the external environment light.

Referring to fig. 3 and 4, the display screen assembly 10 may include a panel 11 and a display screen 12, the panel 11 is disposed on a side of the display screen 12 away from the fixed housing 30, and the display screen 12 is connected to the fixed housing 30. The panel 11 has a display area 112 that exposes information displayed by the display screen 12, and a non-display area 114 that blocks light emitted from the display screen 12 to the outside. The display 12 is used for displaying information, such as images, video or text. The non-display area 114 may also be used to reserve installation space for components such as a microphone net.

In the non-extended state, the projection of the camera module 40 onto the plane of the display screen 12 is at least partially overlapped with the display area 112 of the display screen assembly 10.

In an embodiment, in a non-extended state, the projection of the camera module 40 on the plane where the display screen 12 is located overlaps with the display area 112 of the display screen assembly 10 (as shown in fig. 3), and in an extended state, the camera module 40 can slide out from the end of the fixed housing 30 along with the lifting housing 20, so that the camera module 40 does not occupy the spatial position of the non-display area 114 of the display screen assembly 10 to obtain the ambient light, the area of the display area 112 is enlarged, and the area of the non-display area 114 is reduced. At this time, components such as a headphone, a distance sensor, a light sensor, a dot matrix projector, and the like may be disposed at the position of the non-display region 114.

In another embodiment, in a non-extended state, the projection of the camera module 40 on the plane of the display screen 12 completely overlaps with the display area 112 of the display screen assembly 10 (as shown in fig. 4), and in an extended state, the camera module 40 can slide out from the end of the fixed housing 30 along with the lifting housing 20, so that the camera module 40 does not occupy the spatial position of the non-display area 114 of the display screen assembly 10 to obtain the ambient light, the area of the display area 112 is further enlarged, and the area of the non-display area 114 is further reduced.

Wherein, the components of the handset, the distance sensor, the light sensor, the dot matrix projector, etc. that need to occupy the spatial position of the non-display area 114 of the display screen assembly 10 can be disposed at other positions except the display area 114. For example: at least one of the components such as the earpiece, the distance sensor, the light sensor, and the dot matrix projector may be disposed in the lifting housing 20, so as to further enlarge the area of the display region 112 and further reduce the area of the non-display region 114, thereby achieving the effect that the display region 112 of the display screen assembly 10 approximately completely replaces the spatial position of the non-display region 114.

Referring to fig. 5, 6 and 7, the power mechanism 50 includes a rack 51, a gear 52 and a motor 53, the rack 51 is disposed in the lifting housing 20, the motor 53 is fixed in the fixed housing 30, the gear 52 is connected to an output end of the motor 53, and the motor 53 drives the gear 52 to roll along a rack slot 511 of the rack 51, so that the rack 51 and the gear 52 are relatively displaced, and the lifting housing 20 slides relative to the fixed housing 30, and finally the camera module 40 (see fig. 3 and 4) can be switched between two states, i.e., not shielded by the fixed housing 30 or shielded by the fixed housing 30, in a process that the lifting housing 20 slides relative to the fixed housing 30.

Wherein, the motor 53 can rotate under the power-on state, and can change the direction of rotation according to the direction of the current, so that the gear 52 can rotate in the forward direction or rotate in the reverse direction, and then can change the sliding direction of the gear 52 relative to the rack 51, and finally the lifting housing 20 can move away from the fixed housing 30 or move close to the fixed housing 30. In addition, the motor 53 may determine a rotation speed thereof according to the magnitude of the current, so that the lifting housing 20 may slide at various speeds with respect to the fixed housing 30.

The rack 51 is a straight bar, the longitudinal direction of the rack 51 is the direction in which the plurality of rack grooves 511 on the rack 51 extend, and as already described with reference to fig. 6 and 7, the longitudinal direction of the rack 51 is the same as the sliding direction of the lifting housing 20 (see fig. 3 and 4), the gear 52 may be a spur gear 52, and the axial direction of the motor 53 is perpendicular to the longitudinal direction of the rack 51, so that the overall length of the power mechanism 50 is reduced in the longitudinal direction of the rack 51, and the overall size of the lifting housing 20 is reduced in the sliding direction of the lifting housing 20. On the premise that the overall length of the electronic device is fixed, the overall size of the lifting housing 20 in the sliding direction of the lifting housing 20 is reduced, which means that the overall size of the fixing housing 30 in the sliding direction of the lifting housing 20 can be increased, so that the fixing housing 30 can obtain a larger accommodating space, for example, the size of a battery can be made larger, and the battery capacity of the electronic device is increased.

The power mechanism 50 further comprises a fixing frame 54, the fixing frame 54 is assembled on the fixed shell 30, the gear 52 is fixedly connected with the output end of the motor 53 and rotatably connected with the fixing frame 54, and the rack 51 is slidably connected with the fixing frame 54; wherein the pinion 52 rotates relative to the fixed frame 54 and rolls along the rack slot 511 of the rack 51, so that the rack 51 slides relative to the fixed frame 54.

Referring to fig. 5 to 8, the fixing frame 54 includes a first blocking plate 541, a second blocking plate 542, and a third blocking plate 543 sequentially connected to the first blocking plate 541, the first blocking plate 541 and the third blocking plate 543 are disposed opposite to each other, the gear 52 is connected to the first blocking plate 541 and rotatably connected to the motor 53 through the third blocking plate 543, i.e., the third blocking plate 543 is disposed between the gear 52 and the motor 53, the rack 51 is disposed between the first blocking plate 541 and the third blocking plate 543, and the rack 51 is slidably connected to the first blocking plate 541 and the third blocking plate 543, respectively.

Opposite sides of the rack 51 are respectively engaged with the sliding protrusions 544 of the first and

third shutters

541 and 543, thereby achieving a structural effect of being slidable with respect to the first and

third shutters

541 and 543.

First barrier 541 has adjacent first side surface 5411 and first top surface 5412, sliding projection 544 is disposed on first side surface 5411, first top surface 5412 is an end surface of first barrier 541 facing away from second barrier 542, a contact surface of sliding projection 544 with first side surface 5411 is set to be sunken with respect to first top surface 5412, that is, sliding projection 544 does not exceed first top surface 5412; the third barrier 543 has a second side surface 5431 and a second top surface 5432 which are adjacent to each other, the second side surface 5431 is provided with a sliding projection 544, the second top surface 5432 is an end surface of the third barrier 543 facing away from the second barrier 542, and a contact surface of the sliding projection 544 with the second side surface 5431 is arranged in a sunken manner with respect to the second top surface 5432, that is, the sliding projection 544 does not exceed the second top surface 5432.

The "sinking" in the present embodiment is merely used to explain the relative positional relationship of the slide protrusion 544 with the first and second

top surfaces

5412 and 5432 in a certain posture (as shown in fig. 8), and if the certain posture is changed, the directional indication is changed accordingly.

Referring to fig. 5 to 10, the rack 51 has a first surface 512, a second surface 513 and a third surface 514 connected in sequence, the first surface 512 and the third surface 514 are disposed opposite to each other, a rack slot 511 for cooperating with the gear 52 is disposed on the second surface 513, sliding slots 515 are disposed on both the first surface 512 and the third surface 514 in a length direction (marked on fig. 9) of the rack 51, and the sliding protrusion 544 is clamped in the sliding slots 515 and can slide along the sliding slots 515. Since the sliding protrusion 544 is blocked by the inner surface of the sliding groove 515 during sliding, the sliding groove 515 and the sliding protrusion 544 cooperate to guide the fixing frame 54, thereby ensuring stable sliding of the fixing frame 54 in a predetermined direction.

The rack 51 further has a fourth surface 516 connected to the first surface 512 and the third surface 514, the fourth surface 516 is disposed opposite to the second surface 512, when the sliding protrusion 544 is clamped in the sliding groove 515, the fourth surface 516 is disposed at an interval relative to the first top surface 5412 and the second top surface 5432 of the fixing frame 54, the fourth surface 516 does not exceed the first top surface 5412 and the second top surface 5432 of the fixing frame 54, and the rack 51 is completely accommodated between the first baffle 541 and the third baffle 543 (refer to fig. 10).

In one embodiment, the rack 51 penetrates the first surface 512 and the third surface 514 to form a limiting hole 517, and the length of the limiting hole 517 is smaller than that of the sliding groove 515. The power mechanism 50 further includes a limiting post 55, and the limiting post 55 is assembled on the first barrier 541 and the second barrier 542 and passes through the limiting hole 517. In the process that the lifting housing 20 excessively extends or excessively retracts to the fixed housing 30, the limiting column 55 is matched with the inner wall of the limiting hole 517, so that the lifting housing 20 is prevented from excessively stretching the fixed housing 30 or impacting the fixed housing 30, and the rack 51 is guaranteed to only run within the length distance of the limiting hole 517. Further, the rack 51 penetrates the bottom of the sliding groove 515, and a limiting hole 517 is formed.

Referring to fig. 5 to 8 and fig. 11, the difference between the present embodiment and the previous embodiment is that at least one of the first surface 512 and the third surface 514 is provided with a limiting groove 518, and the length of the limiting groove 518 is smaller than the length of the sliding groove 515. The power mechanism 50 further includes a limiting post 55, and the limiting post 55 is assembled on the fixing frame 54 and extends out to be inserted into the limiting groove 518.

When the first surface 512 is provided with the limiting groove 518, the limiting column 55 is assembled on the first baffle 541 and extends out to be inserted into the limiting groove 518; when the third surface 514 is provided with the limiting groove 518, the limiting column 55 is assembled on the third blocking plate 543 and extends out to be inserted into the limiting groove 518; when the first surface 512 and the third surface 514 are both provided with the position-limiting grooves 518, the first baffle 541 and the third baffle 543 are both provided with the position-limiting columns 55 and extend out to be inserted into the position-limiting grooves 518 of the corresponding positions. In the process of excessively extending or excessively retracting the lifting housing 20 to the fixing housing 30, the limiting column 55 is engaged with the inner wall of the limiting groove 518, so as to prevent the lifting housing 20 from excessively stretching the fixing housing 30 or impacting the fixing housing 30, thereby ensuring that the rack 51 only runs within the length distance of the limiting groove 518. Further, a limit groove 518 is opened on the bottom of the slide groove 515.

Referring to fig. 5 to 10, the power mechanism 50 further includes a gear box 56 and a bearing 57, the gear box 56 is respectively connected to the output end of the motor 53 and the gear 52, the bearing 57 is accommodated in the first blocking plate 541 in an interference fit manner, and the gear 52 is rotatably connected to the first blocking plate 541 through the bearing 57.

Referring to fig. 12, the difference between the present embodiment and the above embodiments is that the second blocking plate 542 of the fixing frame 54 protrudes at a position corresponding to the gear 52 to form an expansion space. It can be understood that the second shutter 542 of the fixing frame 54 is set down at a position where the gear 52 is not provided, relative to the second shutter 542 at a position where the gear 52 is provided, so that the overall volume of the fixing frame 54 is reduced. Given a certain accommodation volume of the stationary housing 30, the overall volume of the fixing frame 54 is reduced, so that the stationary housing 30 can accommodate other components in more space.

Referring to fig. 5, 13 and 14, the fixed housing 30 includes a first bottom plate 31 and a first side plate 32, the first side plate 32 is bent and extended from a side surface of the first bottom plate 31 to form an opening 33 together with the first bottom plate 31, and when the lifting housing 20 is accommodated in the opening 33 in a non-protruding state, an outer circumferential surface of the lifting housing 20 is flush with an outer circumferential surface of the fixed housing 30 (see fig. 1).

The fixing frame 54 is disposed on the first bottom plate 31 and connected to the first bottom plate 31, the display screen assembly 10 is fixed on one side of the first bottom plate 31 away from the rack 51, the lifting housing 20 includes a second bottom plate 21 corresponding to the first bottom plate 31 and a second side plate 22 corresponding to the first side plate 32, the second bottom plate 21 is provided with a first opening 23, the second side plate 22 is provided with a second opening 24, and the first opening 23 and the second opening 24 are communicated with each other so that the lifting housing 20 avoids the motor 53, the fixing frame 54, the gearbox 56 and other parts in the sliding process.

The first bottom plate 31 is convexly provided with a mounting part 34, the fixing frame 54 is mounted on the mounting part 34, and the mounting part 34 can lift the fixing frame 54, so that the distance from the fixing frame 54 to the first bottom plate 31 is greater than the distance from the second bottom plate 21 to the first bottom plate 31. So that the first base plate 31 does not cross-contact the fixed frame 54 during the sliding of the elevating housing 20. At this time, the first opening 23 is used for avoiding the installation portion 34, the length of the first opening 23 is determined by the length of the installation portion 34 in the sliding direction of the lifting shell 20, and when the length of the fixing frame 54 is greater than the length of the installation portion 34 in the sliding direction of the lifting shell 20, the length of the first opening 23 can be smaller than the length of the fixing frame 54, so that the size of the first opening 23 is reduced, and the difficulty of waterproof design of the lifting shell 20 is further reduced.

The elevating housing 20 further includes a third base plate 25 connected to the second side plate 22 and disposed opposite to the second base plate 21.

The camera module 40 includes a front camera 41, the front camera 41 is accommodated in the lifting housing 20, and a lens of the front camera faces the second base plate 21, and when the lifting housing 20 slides out of the opening 33, the ambient light can enter the front camera through the second base plate 21. It should be noted that, at this time, the electronic device may enter the photographing mode or may not enter the photographing mode, for example, when the lifting housing 20 slides out of the opening 33, the electronic device may activate the dot matrix projector to perform face recognition unlocking, and the electronic device may also activate the light sensor to obtain ambient light information.

The camera module 40 further includes a rear camera 42, the rear camera 42 is accommodated in the lifting housing 20, and a lens of the rear camera 42 faces the third bottom plate 25, when the lifting housing 20 slides out of the opening 33, the ambient light passes through the third bottom plate 25 and enters the rear camera 42, so as to avoid opening a hole on the fixing housing 30 for enabling the ambient light to irradiate and enter the fixing housing 30, and further ensure the integrity of one side of the fixing housing 30 far away from the display screen assembly 10.

In this embodiment, the electronic device includes a camera module 40, a lifting housing 20, a fixed housing 30 and an actuating mechanism 50, the camera module 40 is fixed in the lifting housing 20, the lifting housing 20 is connected to the fixed housing 30, and the lifting housing 20 can slide relative to the fixed housing 30 through the actuating mechanism 50; the power mechanism 50 includes a rack 51, a gear 52 and a motor 53, the rack 51 is disposed on the fixed housing 30, the motor 53 is fixed in the lifting housing 20, the gear 52 is connected to the motor 53, the motor 53 is configured to drive the gear 52 to roll along a rack slot 511 of the rack 51, so that the lifting housing 20 slides relative to the fixed housing 30, and thus the camera module 40 can be switched between two states, i.e., being not shielded by the fixed housing 30 and being shielded by the fixed housing 30, so as to achieve the purpose of freely extending and retracting the camera module 40, and further avoid opening a through hole for the camera module 40 to receive ambient light on the electronic device.

If the consumer need not transfer camera module 40, lift casing 20 just can retract electronic device's inside, and camera module 40 is sheltered from by fixed casing 30, if the consumer need transfer camera module 40, lift casing 20 just can stretch out from electronic device's inside, and camera module 40 is not sheltered from by fixed casing 30. Therefore, the camera module 40 does not occupy the position space of the non-display area 114 of the display screen assembly 10, so that the area of the display area 112 of the display screen assembly 10 is further enlarged, the area of the non-display area 114 is further reduced, and the overall aesthetic property of the electronic device is improved. In addition, the motor 53 can control the current to achieve the purpose of providing different rotation speeds for the gear 52, and further accurately control the sliding speed of the lifting housing 20, so as to meet different photographing experiences of a user.

Referring to fig. 1, fig. 2, fig. 5 and fig. 15, the electronic device includes a camera module 40, a lifting housing 20, a fixing housing 30 and a power mechanism 50, wherein the camera module 40 is fixed in the lifting housing 20; the power mechanism 50 includes a rack 51, a gear 52 and a motor 53, the rack 51 is disposed on the lifting housing 20, the motor 53 is fixed in the fixed housing 30, and the gear 52 is connected to the motor 53.

When the control command is a command for calling the camera to work, the electronic device supplies a forward current to the motor 53, and when the control command is a command for finishing the work of the camera, the electronic device supplies a reverse current to the motor 53. The forward current means that the motor 53 can drive the gear 52 to rotate forward, so that the lifting housing 20 can move in a direction away from the fixed housing 30, and then the lifting housing 20 drives the camera module 40 to extend out of the electronic device without being shielded by the fixed housing 30. The reverse current means that the motor 53 can drive the gear 52 to rotate reversely, so that the lifting housing 20 can move toward the direction close to the fixed housing 30, and the lifting housing 20 drives the camera module 40 to slide into the electronic device and be shielded by the fixed housing 30. In addition, the motor 53 may determine the rotation speed according to the magnitude of the current, so that the lifting housing 20 moves at different speeds.
