It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The electronic device provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

Referring to fig. 1 to 13, an embodiment of the present application discloses an electronic apparatus including a first housing 100, a second housing 200, a flexible display 300, a camera module 400, and a driving mechanism 500.

The first housing 100 and the second housing 200 are both base members of the electronic device, and can provide a mounting base for other components of the electronic device. The second housing 200 is slidably connected to the first housing 100, i.e. the second housing 200 and the first housing 100 are capable of relative movement.

The first section of the flexible display 300 is connected to the first housing 100, alternatively, the first section of the flexible display 300 may be connected to the first housing 100 by bonding, etc., which is not particularly limited in the embodiment of the present application. The second section of the flexible display 300 is slidably matched with the second housing 200, that is, the second section of the flexible display 300 and the second housing 200 can move relatively, and the flexible display 300 is provided with a light through hole 310, and the light through hole 310 is mainly used for light passing.

Optionally, the flexible display 300 includes a cover 320, a display main body 330, and a supporting member 340, where the cover 320, the display main body 330, and the supporting member 340 are sequentially stacked, the supporting member 340 is mainly used for supporting the display main body 330, a first section of the supporting member 340 and the first housing 100 may be connected in an adhesive manner, and the second section of the supporting member 340 is slidably matched with the second housing 200, and the cover 320 is mainly used for protecting the display main body 330, so as to prevent the display main body 330 from being directly exposed to the outside and damaged.

The camera module 400 is disposed in the first housing 100, and the camera module 400 includes a camera 410, and when the camera 410 is in a shooting mode, light enters the camera 410 through the light-passing hole 310, so as to be imaged. In an alternative embodiment, the camera 410 may be directly placed on the first housing 100, and the camera 410 may move along the inner surface of the first housing 100, but this may cause the movement track of the camera 410 to be easily shifted. Thus, in another alternative embodiment, the camera module 400 further includes a bracket 450, the camera 410 is disposed on the bracket 450, the bracket 450 is provided with a guide rail 451, the first housing 100 is provided with a guide groove 110, and the guide rail 451 is slidably engaged with the guide groove 110. In this embodiment, the guide rail 451 and the guide groove 110 can limit the movement direction of the camera 410 during the movement of the camera 410, so as to prevent the movement track of the camera 410 from shifting, so that the camera 410 faces the light-passing hole 310 more precisely. Further alternatively, the bracket 450 is further provided with a limiting portion, which can be in limiting engagement with the first housing 100, thereby limiting the position of the bracket 450, so that the camera 410 is more reliably maintained in the first position or the second position.

The driving mechanism 500 is disposed in the first housing 100, the driving mechanism 500 is connected to the flexible display 300, the second housing 200, and the camera module 400, the driving mechanism 500 drives the flexible display 300 and the second housing 200 to move relative to the first housing 100 to switch the electronic device between a folded state and an unfolded state, and the driving mechanism 500 drives the camera 410 to move, where the movement mode of the camera 410 may be movement or rotation, and relatively speaking, the space required when the camera 410 moves is smaller. Wherein, when the electronic device is in the folded state, the light-passing hole 310 is in the hidden state, and the flexible display screen 300 blocks light from entering the camera 410; when the electronic device is in the unfolded state, the light-passing hole 310 is in the 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 the electronic device is in a folded state, the camera 410 is in a non-shooting mode, the light passing hole 310 arranged on the flexible display screen 300 is hidden, the flexible display screen 300 blocks light from entering the camera 410, at the moment, a user cannot see the light passing hole 310, the whole size of the electronic device is small, and the portions, located on the outer surface of the electronic device, of the flexible display screen 300 are effective display areas, namely, the screen occupation of the electronic device is large. When the electronic device is in the unfolded state, the driving mechanism 500 drives the flexible display screen 300, the second housing 200 and the camera 410 to move, and as the effective display area of the flexible display screen 300 gradually increases, the light passing hole 310 arranged on the flexible display screen 300 is exposed, when the camera 410 moves to a position opposite to the light passing hole 310, light passes through the light passing hole 310 and enters the camera 410, and at this moment, the camera 410 is still in the electronic device, that is, the camera 410 does not need to extend out of the first housing 100 to shoot, meaning that in this case, no opening is needed to be formed on the first housing 100, so that foreign matters such as water stains, dust and the like can be prevented from entering the electronic device; meanwhile, the camera 410 is always located inside the electronic device, so that the camera 410 can be prevented from being damaged when the electronic device falls. Therefore, the electronic equipment disclosed by the embodiment of the application can solve the problems that the screen occupation of the existing electronic equipment is smaller, the waterproof and dustproof effects are poorer and the electronic equipment is easy to damage when falling. In addition, when the electronic device is in the unfolded state, the effective display area of the flexible display screen 300 is larger, so that the requirement of the 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, alternatively, the driving source 510 may be a motor, a 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 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 environment protection, and the embodiment of the application does not limit the specific form of the driving source 510. The driving source 510 is connected with the transmission assembly 520, the transmission assembly 520 is respectively connected with the flexible display screen 300 and the camera 410, and the driving source 510 simultaneously drives the flexible display screen 300, the second housing 200 and the camera 410 to move 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, the flexible display screen 300 and the camera 410 connected with the transmission assembly 520 move together, at this time, the effective display area of the flexible display screen 300 is gradually increased, and meanwhile, in the moving process of the flexible display screen 300, the transmission assembly 520 drives the second shell 200 to slide relative to the first shell 100, so that the distance between the first shell 100 and the second shell 200 is increased; in addition, during the movement of the flexible display screen 300, the camera 410 also moves until the light passing hole 310 is opposite to the camera 410, and the light enters the camera 410 through the light passing hole 310, that is, the camera 410 can take a photograph. Therefore, the driving structure 500 can make the flexible display screen 300, the second housing 200 and the camera 410 move simultaneously, which is convenient for the electronic device to flexibly switch between the folded state and the unfolded state more quickly, and the driving of the flexible display screen 300, the second housing 200 and the camera 410 can be realized simultaneously by the same driving structure 500, so that the electronic device has fewer parts and lower cost.

In an alternative embodiment, the driving source 510 drives the camera 410 to move between the first position and the second position, and the camera 410 has a light inlet end. The flexible display 300 may be always located at one side of the light entrance end of the camera 410, regardless of whether the electronic device is in the folded state or the unfolded state, but this arrangement increases the thickness of the electronic device. Therefore, optionally, when 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, the light-passing hole 310 is located at a side of the camera 410 facing away from the light-entering end, that is, when the overall size of the electronic device is smaller, the camera 410 is located in a space formed after the flexible display screen 300 is bent. When the electronic device is in the unfolded state, the light-passing hole 310 is in the exposed state, the camera 410 is in the second position, the light-passing hole 310 is opposite to the light-entering end, and light can enter the camera 410 from the light-passing hole 310. Therefore, in the embodiment of the 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, and the thickness of the electronic device is thinner, thereby improving the comfort level when a user holds the electronic device.

In an alternative embodiment, the moving direction of the camera 410 is a first direction, the driving source 510 is provided with an output shaft, and the axis 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 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 tends to occupy part of the space in the direction, which may cause a great difficulty in setting other components such as the transmission assembly 520. Therefore, alternatively, the axis direction of the output shaft is perpendicular to the first direction, that is, the arrangement direction of the driving source 510 is perpendicular to the moving direction of the camera 410, and at this time, the arrangement position of the driving source 510 may 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, where the transmission belt 523 is wound around the first gear 521 and the second gear 522 and meshed with the first gear 521 and the second gear 522, the first gear 521 is connected to the output shaft, the flexible display 300 and the second housing 200 are both connected to the transmission belt 523, alternatively, a side of the flexible display 300 facing the transmission belt 523 is provided with a first driving tooth, and an outer surface of the transmission belt 523 is provided with a second driving tooth, where the second driving tooth is meshed with the first driving tooth, so as to implement connection between the flexible display 300 and the transmission belt 523. The driving source 510 drives the driving belt 523 to move through the first gear 521, and the driving belt 523 drives the flexible display screen 300 and the second housing 200 to move. When the driving source 510 is operated, the output shaft rotates to drive the first gear 521 to rotate, and the driving belt 523 around the first gear 521 and the second gear 522 moves to drive the flexible display 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 interaxial distance and multiple shafts, thereby enabling the electronic equipment to be more stable in the unfolding process.

In an alternative embodiment, camera module 400 further includes a rack 420, rack 420 is engaged with second gear 522, camera 410 is coupled to rack 420, and belt 523 drives camera 410 between the first position and the second position via rack 420. The driving source 510 drives the first gear 521 to rotate, the driving belt 523 is meshed with the first gear 521 and the second gear 522, the second gear 522 is driven by the driving belt 523 to rotate, and the rack 420 is meshed with the second gear 522, at this time, the rack 420 moves and drives the camera 410 to move. The power of the driving belt 523 can be transmitted to the camera 410 only by adding the rack 420, so that the structure of the camera module 400 is simpler, the driving route is shorter, and the driving 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 meshed with the driving belt 523 and the rack 420, 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 driving belt 523 drives the camera 410 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, and the first gear 521, the second gear 522 and the third gear 430 are all meshed with the driving belt 523, so that the second gear 522 and the third gear 430 rotate under the driving of the driving belt 523, and the third gear 430 is meshed with the rack 420, so that the third gear 430 can drive the rack 420 to move to drive the camera 410 to move. Since a certain distance exists between the first gear 521 and the second gear 522, the setting position of the third gear 430 is flexible, and accordingly, the setting position and length of the rack 420 engaged with the third gear 430 can be flexibly set.

The side of the rack 420 facing the first gear 521 may be provided with all the transmission teeth 421, in which case, when the third gear 430 moves to the end of one end of the rack 420 during the unfolding of the electronic device, the camera 410 is at the second position, which is right opposite to the light-transmitting hole 310; during the collapsing of the electronic device, the camera 410 is in the first position when the third gear 430 moves to the end of the other end of the rack 420. 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, resulting in 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 300 cannot be continuously changed, and thus the display area of the flexible display 300 is limited.

In order to solve the problems of the two embodiments, the rack 420 may optionally include a first portion and a second portion, where 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 light 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 connection between the driving gear 421 and the light 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 not meshed with the transmission gear 421, but faces the light face 422, the light face 422 can provide supporting force for the third gear 430, the third gear 420 is prevented from being suspended, at the moment, 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 process of folding 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 not meshed with the transmission gear 421, but faces the light face 422, the light face 422 can provide supporting force for the third gear 430, the third gear 420 is prevented from being suspended, the light passing hole 310 is hidden at this time, the flexible display screen 300 blocks light 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 move continuously, so that the overall size of the electronic device is further reduced. Therefore, the incomplete rack is adopted in the embodiment of the application, so that the third gear 430 is prevented from suspending, and the limitation on the movement of the flexible display screen 300 is avoided.

It should be noted that the rack 420 including the driving teeth 421 and the light surface 422 may also be suitable for the scheme of meshing the rack 420 with the second gear 522, which is not described herein for brevity.

In an alternative embodiment, the third gear 430 includes a first gear portion 431 and a second gear portion 432, and the first gear portion 431 and the second gear portion 432 are coaxially disposed. Alternatively, the first and second driving

parts

431 and 432 may be provided as an integral structure or a split structure, and if the split structure is adopted, the first and second driving

parts

431 and 432 need to be connected through a fixed shaft, which increases the installation process of the electronic device and increases the cost. Therefore, the first transmission portion 431 and the second transmission portion 432 are alternatively formed as a single structure, so as to facilitate the installation of the electronic device and save cost. The first gear portion 431 is engaged with the driving belt 523, the second gear portion 432 is engaged with the rack 420, and a transmission ratio between the first gear portion 431 and the second gear portion 432 (i.e., a ratio between a radius of the first gear portion 431 and a radius of the second gear portion 432) can be flexibly set, but a situation that the camera 410 is still not moved in place when the light passing hole 310 is exposed easily occurs, resulting in an excessively long photographing preparation time. For this purpose, the transmission ratio L between the first gear portion 431 and the second gear portion 432 may be made to satisfy the following relationship: l=s1/S2; in the process of moving the camera 410 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 moving distances in the moving direction of the camera 410. After such arrangement, when the light-passing hole 310 is exposed, the camera 410 is also moved in place, so that the light-passing hole 310 can be opposite to the camera 410 in the shortest time, and the shooting preparation time is shortened.

Optionally, the driving mechanism 500 disclosed in the embodiment of the present application further includes a speed reducer 530, where the speed reducer 530 is disposed coaxially with the output shaft of the driving source 510, and can obtain a smaller rotation speed, so as to increase the torque and more forcefully drive the driving belt 523 to move. In addition, the decelerator 530, the driving belt 523, the first gear 521 and the second gear 522 may be provided in two groups, and the two groups of driving belts 523, the first gear 521 and the second gear 522 are provided corresponding to both sides of the flexible display screen 300, respectively, so that driving forces are simultaneously applied to both sides of the flexible display screen 300 to move the flexible display screen 300 more stably.

In an alternative embodiment, the camera module 400 further includes an elastic member 440, one end of the elastic member 440 is connected to the camera 410, and the other end of the elastic member 440 is connected to the first housing 100. The elastic member 440 may apply a damping force to the camera 410, thereby making the movement of the camera 410 smoother. In addition, in the embodiment where the camera 410 is connected to the rack 420, the elastic member 440 is deformed during the movement of the rack 420, and when the driving gear 421 of the rack 420 is separated from the second gear 522 or the third gear 430, the rack 420 will move continuously under the action of its own inertia, and at this time, the elastic member 440 will have a tendency to recover deformation, and the elastic member 440 will prevent the rack 420 from moving continuously, so that the rack 420 will be kept in a stationary state reliably. Therefore, in the embodiment of the present application, the camera 410 is more reliably maintained in the first position and the second position by providing the elastic member 440.

In another alternative embodiment, the electronic device further includes a first bracket 600 and a second bracket 700, where the first bracket 600 is slidably connected to the second bracket 700, the first bracket 600 is connected to the first housing 100, and the second bracket 700 is connected to the second housing 200, i.e., the second bracket 700 and the first bracket 600 can slide relatively. The second bracket 700 is in contact with the flexible display screen 300, and the driving mechanism 500 drives the second housing 200 to move through the second bracket 700. The first bracket 600 and the second bracket 700 can provide supporting force for the flexible display screen 300, so that the surface of the effective display area of the flexible display screen 300 is smoother; meanwhile, the user has better use experience when performing touch operation.

In a further alternative embodiment, the first bracket 600 is provided with a plurality of sliding grooves 610 arranged at intervals along the second direction, the second bracket 700 is provided with a plurality of sliding rails 710 arranged at intervals along the second direction, and each sliding rail 710 is matched with each sliding groove 610 in a one-to-one correspondence manner; wherein the second direction is perpendicular to the sliding direction of the second bracket 700. In the process that the driving mechanism 500 drives the second bracket 700 to move, each sliding rail 710 moves along each sliding groove 610, and the sliding grooves 610 provide guidance for the movement of the sliding rail 710, so that the second bracket 700 moves along the preset direction of the sliding grooves 610, and the second bracket 700 is prevented from being deviated, and the surface of the flexible display screen 300 is prevented from being wrinkled; secondly, by adopting the sliding fit mode of the sliding rail 710 and the sliding groove 610, the internal structure of the electronic equipment is more stable when the electronic equipment is switched between the folded state and the unfolded state.

The connection mode between the driving belt 523 and the second bracket 700 is selected in various ways, for example, the end of the second bracket 700 may be directly adhered to the side of the driving belt 523, but in this connection mode, since the driving belt 523 is thinner, the connection area between the driving belt 523 and the second bracket 700 is smaller, and the connection strength between the driving belt 523 and the second bracket 700 is not high. In view of this, in other embodiments, the driving belt 523 is provided with an extension portion 523a protruding in the axial direction of the first gear 521, the second bracket 700 is provided with a connection portion 720, the connection portion 720 extends in the moving direction of the second bracket 700, the extension portion 523a is connected to the connection portion 720, and the driving belt 523 drives the second bracket 700 to move through the extension portion 523 a. The extending portion 523a does not affect the cooperation between the first gear 521 and the second gear 522 and the driving belt 523, so the shape and size of the extending portion 523a and the connection position of the extending portion 523a and the connecting portion 720 can be optimized, so that the connection area of the extending portion 523a and the connecting portion 720 is larger, and the connection strength of the extending portion 523a and the connecting portion 720 is improved.

Optionally, the extension portion 523a has a first face and a second face, where the first face and the second face are disposed opposite to each other in the thickness direction of the electronic device, the first face may be flush with the outer surface of the driving belt 523, and the second face may be recessed with respect to the inner surface of the driving belt 523, so that the extension portion 523a is ensured to have a sufficient thickness, and a larger disposition space may be reserved for the connection portion 720. The connection portion 720 may be connected to a second face of the extension portion 523a, and the second face may be sized larger, thereby increasing a connection area of the connection portion 720 and the extension portion 523 a.

In a further embodiment, the first bracket 600 is provided with a fitting groove 620, and the connection portion 720 is slidably fitted with the fitting groove 620. The engaging groove 620 can limit the movement direction of the second bracket 700 during the movement of the second bracket 700 by the driving belt 523, thereby realizing the guiding function. Further, a ball 630 is provided in the engagement groove 620, and the connection portion 720 is engaged with the engagement groove 620 through the ball 630. The connection portion 720 and the engagement groove 620 are engaged with the balls 630 in a rolling manner, and the friction force generated by the engagement manner is small, so that the connection portion 720 and the engagement groove 620 can slide relatively smoothly, and the service lives of the connection portion and the engagement groove 620 are prolonged.

Optionally, the electronic device disclosed in the embodiment of the present application further includes a coil spring, a circuit board 810, a battery 820, a speaker 830, and the like, which are provided to the first housing 100. One end of the coil spring is connected with the first housing 100, and the other end of the coil spring is connected with the flexible display screen 300, and in the process of switching the electronic device from the unfolded state to the folded state, the coil spring continuously stores the retracted flexible display screen 300 through the retraction force of the coil spring, so that the unretracted flexible display screen 300 is always in a tight state, and wrinkles caused by the looseness of the flexible display screen 300 can be prevented. The camera module 400 and the driving mechanism 500 may be connected to the circuit board 810 through a flexible circuit board, and the battery 820 and the speaker 830 may be connected to the circuit board 810 through a board-to-board connector having a light and thin characteristic, and in addition, the circuit board 810, the battery 820 and the speaker 830 are sequentially arranged and arranged side by side, so that the thickness of the electronic device is thinner, and the user experience is improved.
