The display 12 is used for information display, and displays information such as images, videos, or texts. The non-display area 114 may also be used to reserve installation space for components such as the earpiece mesh.
In the non-extended state, the projection of the camera module 40 on the plane of the display 12 is at least partially overlapped with the display area 112 of the display assembly 10.
In an embodiment, in the non-extended state, the projection of the camera module 40 on the plane on which the display screen 12 is located is partially overlapped with the display area 112 of the display screen assembly 10 (as shown in fig. 3), in the 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, and the area of the display area 112 is enlarged, and the area of the non-display area 114 is reduced. At this time, the earpiece, the distance sensor, the light sensor, the dot matrix projector, etc. may be disposed at the position of the non-display area 114.

Wherein components of the earpiece, distance sensor, light sensor, dot matrix projector, etc. that need to occupy the spatial position of the non-display area 114 of the display screen assembly 10 may be located in other locations than the display area 114. For example: at least one of the parts such as the receiver, the distance sensor, the light sensor, the dot matrix projector, etc. may be disposed on the lifting housing 20, so that the area of the display area 112 is further enlarged, and the area of the non-display area 114 is further reduced, thereby realizing the effect that the display area 112 of the display screen assembly 10 approximately completely replaces the spatial position of the non-display area 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 with an output end of the motor 53, 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 (refer to fig. 3 and 4) can be switched in two states of being not blocked by the fixed housing 30 or being blocked by the fixed housing 30 in the process of sliding the lifting housing 20 relative to the fixed housing 30.
Wherein the motor 53 may be rotated in an energized state and the direction of rotation may be changed according to the direction of current flow, so that the gear 52 may be rotated in a forward direction or in a reverse direction, and thus the sliding direction of the gear 52 with respect to the rack 51 may be changed, and finally the lifting housing 20 may be moved away from the fixed housing 30 or moved close to the fixed housing 30. In addition, the motor 53 may determine the rotation speed thereof according to the magnitude of the current, so that the elevation housing 20 may slide with respect to the fixed housing 30 at different speeds.
The rack 51 is in a straight bar shape, the length direction of the rack 51 is the extending and laying direction of the plurality of rack grooves 511 on the rack 51, the length direction of the rack 51 is the same as the sliding direction of the lifting housing 20 (refer to fig. 3 and 4), the gear 52 may be a straight gear 52, and the axial direction of the motor 53 is perpendicular to the length direction of the rack 51, so that the overall length of the power mechanism 50 is reduced in the length 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 fixed housing 30 in the sliding direction of the lifting housing 20 can be increased, so that a larger accommodating space, such as a larger size of a battery, can be obtained by the fixed housing 30, and the battery capacity of the electronic device is increased.

The "sinking" in this embodiment is merely used to explain the relative positional relationship between the sliding protrusion 544 and the first top surface 5412 and the second top surface 5432 in a specific posture (as shown in fig. 8), and if the specific 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 being matched with the gear 52 is disposed on the second surface 513, a sliding slot 515 is disposed on each of the first surface 512 and the third surface 514 in a length direction (labeled in fig. 9) of the rack 51, and the sliding protruding portion 544 is clamped in the sliding slot 515 and can slide along the sliding slot 515. Since the sliding protrusion 544 is blocked by the inner side 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 that the fixing frame 54 slides stably in a predetermined direction.

The power mechanism 50 further includes a limiting post 55, and the limiting post 55 is assembled on the first baffle 541 and the second baffle 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 limit posts 55 are matched with the inner wall of the limit 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 ensured to only run within the length distance of the limit hole 517. Further, the rack 51 is provided with a limiting hole 517 penetrating through the bottom of the chute 515.
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.

Referring to fig. 12, the difference between the present embodiment and the above embodiment is that the second baffle 542 of the fixing frame 54 protrudes to form a capacity expansion space at a position corresponding to the gear 52. It can be appreciated that the position of the second baffle 542 of the mount 54 where the gear 52 is not provided is disposed to sink with respect to the position of the second baffle 542 where the gear 52 is provided, thereby reducing the overall volume of the mount 54. With the volume of the fixed housing 30, the overall volume of the fixed frame 54 is reduced, thereby allowing the fixed housing 30 to accommodate other components with 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, and 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 the non-extended state, an outer peripheral surface of the lifting housing 20 is flush with an outer peripheral surface of the fixed housing 30 (refer to fig. 1).

The first bottom plate 31 is provided with a mounting portion 34 in a protruding manner, the fixing frame 54 is mounted on the mounting portion 34, and the mounting portion 34 can lift the fixing frame 54, so that the distance between the fixing frame 54 and the first bottom plate 31 is greater than the distance between the second bottom plate 21 and the first bottom plate 31. So that the first bottom plate 31 does not have cross contact with the fixing frame 54 during the sliding of the elevation housing 20. At this time, the first opening 23 is configured to avoid the mounting portion 34, the length of the first opening 23 is determined by the length of the mounting portion 34 in the sliding direction of the lifting housing 20, and when the length of the fixing frame 54 is greater than the length of the mounting portion 34 in the sliding direction of the lifting housing 20, the length of the first opening 23 may be smaller than the length of the fixing frame 54, thereby reducing the size of the first opening 23 and further reducing the waterproof design difficulty of the lifting housing 20.

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 bottom plate 21, when the lifting housing 20 slides out of the opening 33, ambient light can pass through the second bottom plate 21 and enter the front camera. It should be noted that, at this time, the electronic device may enter a photographing mode or not, 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 acquire the 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, ambient light passes through the third bottom plate 25 and enters the rear camera 42, so that an opening hole in the fixed housing 30 is avoided for enabling ambient light to irradiate into the fixed housing 30, and further, the integrity of one side of the fixed housing 30 away from the display screen assembly 10 is ensured.
In this embodiment, the electronic device includes a camera module 40, a lifting housing 20, a fixed housing 30, and a power mechanism 50, where 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 power mechanism 50; the power mechanism 50 comprises a rack 51, a gear 52 and a motor 53, the rack 51 is arranged on the fixed shell 30, the motor 53 is fixed in the lifting shell 20, the gear 52 is connected with the motor 53, the motor 53 is used for driving the gear 52 to roll along a rack groove 511 of the rack 51 so as to enable the lifting shell 20 to slide relative to the fixed shell 30, and therefore the camera module 40 can be switched between the state of being not blocked by the fixed shell 30 and the state of being blocked by the fixed shell 30, the purpose that the camera module 40 stretches out and draws back freely is achieved, and further the situation that a through hole for the camera module 40 to receive ambient light is formed in an electronic device is avoided.
