In an alternative embodiment, the camera 410 may be directly placed on the first casing 100, and the camera 410 may move along the inner surface of the first casing 100, but this way may cause the movement track of the camera 410 to be easily deviated.

The driving mechanism 500 is disposed in the first casing 100, the driving mechanism 500 is connected to the flexible display screen 300, the second casing 200 and the camera module 400, the driving mechanism 500 drives the flexible display screen 300 and the second casing 200 to move relative to the first casing 100 so as to switch the electronic device between the folded state and the unfolded state, the driving mechanism 500 drives the camera 410 to move, the movement form of the camera 410 can be moving or rotating, and relatively speaking, the space required by the movement of the camera 410 is smaller. Under the condition that the electronic device is in a folded state, the light-passing hole 310 is in a hidden state, and the flexible display screen 300 blocks light rays from entering the camera 410; when the electronic device is in the unfolded state, the light-passing hole 310 is in an exposed state, the camera 410 is opposite to the light-passing hole 310, and light can enter the camera 410 from the light-passing hole 310.
Under the condition that electronic equipment is in the folded state, camera 410 is in the non-mode of shooing, and the clear aperture 310 that sets up on flexible display screen 300 is hidden, and flexible display screen 300 blocks light and gets into camera 410, and the user can't see clear aperture 310 this moment, and electronic equipment's overall dimension is less, and the part that lies in the electronic equipment surface in the flexible display screen 300 is effective display area, and electronic equipment's screen accounts for than great promptly. Under the condition that the electronic device is in an unfolded state, the driving mechanism 500 drives the flexible display screen 300, the second housing 200 and the camera 410 to move, along with the gradual increase of the effective display area of the flexible display screen 300, the light through hole 310 arranged on the flexible display screen 300 is exposed, when the camera 410 moves to a position opposite to the light through hole 310, light rays penetrate through the light through hole 310 to enter the camera 410, and at the moment, the camera 410 is still in the electronic device, namely, the camera 410 does not need to extend out of the first housing 100 to shoot, which means that under the condition, an opening does not need to be formed on the first housing 100, so that foreign matters such as water stain, dust and the like can be prevented from entering the inside of the electronic device; meanwhile, the camera 410 is always located inside the electronic device, and when the electronic device falls, the camera 410 can be prevented from being damaged. Therefore, the electronic equipment disclosed by the embodiment of the application can solve the problems that the screen of the existing electronic equipment is small in duty ratio, poor in waterproof and dustproof effects and easy to damage when falling. In addition, under the condition that the electronic device is in the unfolded state, the effective display area of the flexible display screen 300 is large, and the requirement of a user on the large-screen electronic device can be met.
In an alternative embodiment, the driving mechanism 500 includes a driving source 510 and a transmission assembly 520, and the driving source 510 may be an electric motor, an air cylinder, a hydraulic cylinder, a piezoelectric ceramic, a shape memory alloy, or the like, wherein: the motor has the characteristics of small volume, high efficiency and convenient control; the air cylinder and the hydraulic cylinder have the characteristics of large output force and stable and reliable performance; the piezoelectric ceramic and the shape memory alloy have the characteristics of green and environmental protection, and the embodiment of the present application does not limit the specific form of the driving source 510. The driving source 510 is connected to the transmission assembly 520, the transmission assembly 520 is respectively connected to the flexible display screen 300 and the camera 410, and the driving source 510 drives the flexible display screen 300, the second housing 200 and the camera 410 to move simultaneously through the transmission assembly 520. When the flexible display screen 300 of the electronic device needs to be unfolded, the driving source 510 drives the transmission assembly 520 to move, and the flexible display screen 300 connected with the transmission assembly 520 and the camera 410 move together, at this time, the effective display area of the flexible display screen 300 is gradually increased, and meanwhile, in the process of the movement of the flexible display screen 300, the transmission assembly 520 drives the second housing 200 to slide relative to the first housing 100, so that the distance between the first housing 100 and the second housing 200 is increased; in addition, in the process of the movement of the flexible display screen 300, the camera 410 also moves until the light through hole 310 is opposite to the camera 410, and light rays pass through the light through hole 310 and enter the camera 410, that is, the camera 410 can shoot. Therefore, by adopting the driving structure 500, the flexible display screen 300, the second housing 200 and the camera 410 can move simultaneously, which is convenient for the electronic device to switch flexibly between the folded state and the unfolded state more quickly, and the same driving mechanism 500 can drive the flexible display screen 300, the second housing 200 and the camera 410 simultaneously, so that fewer parts and lower cost are included in the electronic device.
In an alternative embodiment, the driving source 510 drives the camera 410 to move between a first position and a second position, the camera 410 having a light entrance end. No matter the electronic device is in the folded state or the unfolded state, the flexible display 300 may be always located on one side of the light inlet end of the camera 410, but this arrangement increases the thickness of the electronic device. Therefore, optionally, under the condition that the electronic device is in the folded state, the light-passing hole 310 is in the hidden state, the flexible display screen 300 blocks light from entering the camera 410, the camera 410 is in the first position, and the light-passing hole 310 is located on the side of the camera 410 away from the light-entering end, that is, when the overall size of the electronic device is small, the camera 410 is located in the space formed after the flexible display screen 300 is bent. Under the condition that the electronic device is in the unfolded state, the light through hole 310 is in the exposed state, the camera 410 is in the second position, the light through hole 310 is opposite to the light inlet end, and light can enter the camera 410 from the light through hole 310. Therefore, in the embodiment of the present application, the camera 410 is disposed in the space formed after the flexible display screen 300 is bent, so that the space in the electronic device can be fully utilized, the thickness of the electronic device is relatively thin, and the comfort level when the user holds the electronic device is improved.
In an alternative embodiment, the moving direction of the camera 410 is the first direction, the driving source 510 is provided with an output shaft, the axial direction of the output shaft may be parallel to the moving direction of the camera 410, and the driving source 510 drives the flexible display screen 300, the second housing 200 and the camera 410 to move simultaneously through the transmission assembly 520, if the setting direction of the driving source 510 is parallel to the moving direction of the camera 410, the driving source 510 will occupy a part of the space in the direction, which will bring great difficulty to the setting of other components such as the transmission assembly 520. Therefore, alternatively, the axial direction of the output shaft is perpendicular to the first direction, i.e., the arrangement direction of the driving source 510 is perpendicular to the moving direction of the camera 410, and the arrangement position of the driving source 510 can be reasonably arranged, thereby facilitating the arrangement of the transmission assembly 520 and other components.
In an alternative embodiment, the transmission assembly 520 includes a first gear 521, a second gear 522 and a transmission belt 523, the transmission belt 523 is wound around the first gear 521 and the second gear 522 and is engaged with the first gear 521 and the second gear 522, the first gear 521 is connected to the output shaft, the flexible display screen 300 and the second housing 200 are both connected to the transmission belt 523, optionally, a first driving tooth is disposed on a side of the flexible display screen 300 facing the transmission belt 523, a second driving tooth is disposed on an outer surface of the transmission belt 523, and the second driving tooth is engaged with the first driving tooth, so that the flexible display screen 300 is connected to the transmission belt 523. The driving source 510 drives the transmission belt 523 to move through the first gear 521, and the transmission belt 523 drives the flexible display screen 300 and the second housing 200 to move. When the driving source 510 works, the output shaft rotates to drive the first gear 521 to rotate, and the output shaft moves around the transmission belt 523 arranged on the first gear 521 and the second gear 522, so as to drive the flexible display screen 300 and the second housing 200 to move. The embodiment of the application adopts the belt transmission mode, has simple structure and stable transmission, and can transmit power between larger shaft distance and multiple shafts, thereby enabling the electronic equipment to be more stable in the unfolding process.
In an alternative embodiment, the camera module 400 further includes a rack 420, the rack 420 is engaged with the second gear 522, the camera 410 is connected to the rack 420, and the belt 523 drives the camera 410 to move between the first position and the second position through the rack 420. The driving source 510 drives the first gear 521 to rotate, the transmission belt 523 is meshed with the first gear 521 and the second gear 522, the second gear 522 is driven by the transmission belt 523 to rotate, the rack 420 is meshed with the second gear 522, and at this time, the rack 420 moves and drives the camera 410 to move. This scheme only increases rack 420 and just can be with the power transmission of drive belt 523 to camera 410, and consequently this camera module 400's structure is simpler, and the transmission route is shorter for transmission efficiency is higher.
In another alternative embodiment, the camera module 400 further includes a third gear 430 and a rack 420, the third gear 430 is engaged with the belt 523 and the rack 420, respectively, the third gear 430 is located between the first gear 521 and the second gear 522, the camera 410 is connected to the rack 420, and the belt 523 drives the camera 410 to move between the first position and the second position through the third gear 430 and the rack 420. The driving source 510 drives the first gear 521 to rotate, the first gear 521, the second gear 522 and the third gear 430 are all engaged with the transmission belt 523, so that the second gear 522 and the third gear 430 are driven by the transmission belt 523 to rotate, and the third gear 430 is engaged with the rack 420, so that the third gear 430 can drive the rack 420 to move, so as to drive the camera 410 to move. Since a certain distance exists between the first gear 521 and the second gear 522, the third gear 430 can be flexibly disposed, and accordingly, the disposition position and the length of the rack 420 engaged with the third gear 430 can be flexibly disposed.
The side of the rack 420 facing the first gear 521 may be provided with all the transmission teeth 421, in this case, when the third gear 430 moves to the end of one end of the rack 420 during the unfolding process of the electronic device, the camera 410 is at the second position, which is just opposite to the light-passing hole 310; during the folding process of the electronic device, when the third gear 430 moves to the end of the other end of the rack 420, the camera 410 is in the first position. In the case where the camera 410 is in the first position or the second position, the third gear 430 is suspended with respect to the rack 420, so that the third gear 430 is easily damaged by vibration. If the length of the rack 420 is increased to ensure that the rack 420 always supports the third gear 430, the driving belt 523 must be stopped when the camera 410 reaches the first position and the second position, so that the display area of the flexible display screen 300 cannot be changed continuously, thereby limiting the display area of the flexible display screen 300.
In order to solve the problems of the two embodiments, optionally, the rack 420 includes a first portion and a second portion, the first portion is provided with a driving gear 421 on a side facing the first gear 521, and the second portion is provided with a smooth surface 422 on a side facing the first gear 521, that is, the rack 420 is an incomplete rack, and in a case that the third gear 430 is located at a junction of the driving gear 421 and the smooth surface 422, the camera 410 is located at the first position or the second position. In the process of unfolding the electronic device, the third gear 430 drives the rack 420 to move, when the third gear 430 is opposite to one end of the transmission gear 421, the third gear 430 is no longer meshed with the transmission gear 421, but faces the smooth surface 422, the smooth surface 422 can provide a supporting force for the third gear 430, so as to prevent the third gear 420 from being suspended, at this time, the light-passing hole 310 is opposite to the camera 410, the rack 420 stops moving, and the transmission belt 523 can drive the flexible display screen 300 and the second housing 200 to continue moving, so that the effective display area of the flexible display screen 300 is further increased. In the folding process of the electronic device, the third gear 430 drives the rack 420 to move, when the third gear 430 is opposite to the other end of the transmission gear 421, the third gear 430 is no longer meshed with the transmission gear 421, but faces the smooth surface 422, the smooth surface 422 can provide a supporting force for the third gear 430, so as to prevent the third gear 420 from being suspended, at this time, the light-passing hole 310 is hidden, the flexible display screen 300 blocks light rays from entering the camera 410, the rack 420 stops moving again, and the transmission belt 523 can drive the flexible display screen 300 and the second housing 200 to continue moving, so that the overall size of the electronic device is further reduced. Therefore, the incomplete rack is adopted in the embodiment of the present application, which can prevent the third gear 430 from being suspended, and can also avoid the limitation on the movement of the flexible display screen 300.
It should be noted that the rack 420 including the driving gear 421 and the smooth surface 422 may also be applied to a scheme in which the rack 420 is engaged with the second gear 522, and for brevity of text, details are not described here.
In an alternative embodiment, the third gear 430 includes a first gear part 431 and a second gear part 432, and the first gear part 431 and the second gear part 432 are coaxially disposed. Alternatively, the first transmission part 431 and the second transmission part 432 may be provided as an integral structure, or may be provided as a split structure, and if the split structure is adopted, the first transmission part 431 and the second transmission part 432 need to be connected by a fixed shaft, which increases the installation process of the electronic device and increases the cost. Therefore, the first transmission part 431 and the second transmission part 432 are optionally of an integrated structure, so as to facilitate the installation of the electronic device and save the cost. The first gear portion 431 is meshed with the transmission belt 523, the second gear portion 432 is meshed with the rack 420, and the transmission ratio between the first gear portion 431 and the second gear portion 432 (i.e., the ratio between the radius of the first gear portion 431 and the radius of the second gear portion 432) can be flexibly set, but the situation that the camera 410 still does not move in place when the light-passing hole 310 is exposed is easy to occur, so that the shooting preparation time is too long. For this reason, the gear ratio L between the first gear part 431 and the second gear part 432 may be made to satisfy the following relationship: l is S1/S2; in the process that the camera 410 moves from the first position to the second position, the moving distance of the flexible display screen 300 is S1, and the moving distance of the camera 410 is S2. Here, S1 and S2 are both movement distances in the movement direction of the camera 410.
