The electronic device provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 1 to 9, an electronic device disclosed in the embodiments of the present application includes a device housing 100, an optical module 200, a first driving mechanism 300, and a second driving mechanism 400.
The device case 100 is a basic component of the electronic device, and the device case 100 may be a mounting base of a middle subassembly of the electronic device, one side of the device case 100 in a thickness direction is provided with a first through hole 110, such that the first through hole 110 faces the thickness direction of the electronic device, and further, some components mounted in the device case 100 may protrude to the outside of the device case 100 or retract into the device case 100 through the first through hole 110. It should be noted that, the electronic device is generally configured with a display screen, and the thickness direction of the electronic device is generally perpendicular to the display screen. Of course, the thickness direction of the electronic apparatus coincides with the thickness direction of the apparatus case 100.
The optical module 200 includes a first lens mechanism 210 and a second lens mechanism 220, both the first lens mechanism 210 and the second lens mechanism 220 are light distribution mechanisms, when the electronic device is in a shooting mode, the first lens mechanism 210 and the second lens mechanism 220 are structures which allow ambient light to pass through in the optical module 200 in advance, and the lens mechanisms can optically adjust the ambient light to achieve the purpose of light distribution.
The first driving mechanism 300 and the first lens mechanism 210 are both disposed within the apparatus housing 100, and the first driving mechanism 300 is configured to drive the first lens mechanism 210 to move between a first position and a second position. Specifically, when the electronic device is in the shooting mode, the first driving mechanism 300 may drive the first lens mechanism 210 to move to the first position, so as to implement the shooting function of the electronic device, and when the electronic device finishes shooting, the first driving mechanism 300 may drive the first lens mechanism 210 to move to the second position. Specifically, the first driving mechanism 300 may be connected to the first lens mechanism 210, so as to drive the movement of the first lens mechanism 210. Of course, the first driving mechanism 300 may not be connected to the first lens mechanism 210, and the first driving mechanism 300 may be an electromagnetic driving mechanism, and the purpose of driving the first lens mechanism 210 to move is achieved by a non-contact magnetic force.
A second drive mechanism 400 is provided to the device housing 100, the second drive mechanism 400 being for driving the second lens mechanism 220 to move between the extended position and the retracted position. In the extended position, at least a portion of the second lens mechanism 220 extends out of the apparatus housing 100 through the first through hole 110; in the retracted position, the second lens mechanism 220 is retracted within the device housing 100. Specifically, when the electronic device is in the shooting mode, the second driving mechanism 400 may drive the second lens mechanism 220 to extend out of the device housing 100 through the first through hole 110, at this time, the second lens mechanism 220 is located at the extended position, which is ready for shooting of the electronic device, when the electronic device finishes shooting, the second driving mechanism 400 may drive the second lens mechanism 220 to retract into the device housing 100, at this time, the second lens mechanism 220 is located at the retracted position, thereby achieving storage of the second lens mechanism 220 within the device housing 100.
Similarly, the second driving mechanism 400 may be connected to the second lens mechanism 220, so as to drive the movement of the second lens mechanism 220. Of course, the second driving mechanism 400 may not be connected to the second lens mechanism 220, and the second driving mechanism 400 may be an electromagnetic driving mechanism, and the purpose of driving the second lens mechanism 220 to move is achieved by a non-contact magnetic force.
With the second lens mechanism 220 in the extended position and the first lens mechanism 210 in the first position, the first lens mechanism 210 is superposed on the second lens mechanism 220, in which case ambient light passes through the second lens mechanism 220 and the first lens mechanism 210 in order to optimize the photographing performance of the electronic device while achieving the photographing function of the electronic device.
Alternatively, in the case where the second lens mechanism 220 is superposed on the first lens mechanism 210, the optical axis of the second lens mechanism 220 may coincide with the optical axis of the first lens mechanism 210, so that the photographing quality can be further improved.
With the second lens mechanism 220 in the retracted position and the first lens mechanism 210 in the second position, the first lens mechanism 210 is located on one side of the optical axis of the second lens mechanism 220. In this case, when the electronic device finishes shooting, the second lens mechanism 220 and the first lens mechanism 210 retract into the device housing 100 and move to the second position, respectively, so that the height of the optical module 200 is reduced, and thus the electronic device can be thinned. The second position is not limited by the embodiments of the present application, and the second position may be arranged according to the internal space and components of the device case 100.
The electronic device disclosed in the embodiment of the present application improves the structure of the electronic device in the related art, so that the optical module 200 includes the first lens mechanism 210 and the second lens mechanism 220, and when the electronic device is in the shooting mode, the first driving mechanism 300 and the second driving mechanism 400 respectively drive the first lens mechanism 210 and the second lens mechanism 220 to be stacked, thereby increasing the height of the optical module 200 and ensuring the shooting performance of the electronic device; when the electronic device finishes shooting, the first driving mechanism 300 drives the first lens mechanism 210 to move to the second position, and the second driving mechanism 400 drives the second lens mechanism 220 to retract into the device housing 100, so as to accommodate the second lens mechanism 220 and further reduce the size of the electronic device in the thickness direction, which undoubtedly can solve the contradiction between the height of the optical module 200 in the electronic device and the light and thin development of the electronic device in the background art.
The kinds of the first and second driving mechanisms 300 and 400 may be various, and the first and second driving mechanisms 300 and 400 may be hydraulic, pneumatic telescopic, electromagnetic driving mechanisms, etc. The embodiments of the present application do not limit the specific kinds of the first and second driving mechanisms 300 and 400.
In the electronic apparatus disclosed in the embodiment of the present application, the retracted position may form an escape space in a case where the second lens mechanism 220 is moved to the extended position, and the first lens mechanism 210 may be accommodated in the escape space in a case where the first lens mechanism 210 is located at the first position. In this case, when in the shooting mode, since at least a portion of the second lens mechanism 220 moves to the outside of the device housing 100, a avoiding space is formed at a position where the second lens mechanism 220 is originally arranged, in order to better exert a shooting function of the electronic device, the first lens mechanism 210 and the second lens mechanism 220 are required to jointly complete shooting of the electronic device, that is, the first lens mechanism 210 needs to move to the first position, the first position and the avoiding space at this time may be the same position, so that the first lens mechanism 210 can be accommodated in the avoiding space, so that the space in the electronic device can be fully utilized, and further, the light and thin development of the electronic device can be facilitated.
In the embodiment of the present application, the first lens mechanism 210 may include a first barrel 211 and a first lens 212, and the first lens 212 is mounted inside the first barrel 211. Specifically, one or more first lenses 212 may be provided. When there are a plurality of first mirrors 212, the plurality of first mirrors 212 are arranged in the optical axis direction of the first lens mechanism 210. Of course, when there are a plurality of first lenses 212, the electronic device disclosed in the embodiment of the present application has more obvious advantages in solving the contradiction between the volume of the optical module 200 and the slimness of the electronic device.
Similarly, in the embodiment of the present application, the second lens mechanism 220 may include a second barrel 221 and a second lens 222, and the second lens 222 is mounted in the second barrel 221. Specifically, one or more second lenses 222 may be provided. When there are a plurality of second mirrors 222, the plurality of second mirrors 222 are arranged in the optical axis direction of the second lens mechanism 220. Of course. In the case that there are a plurality of second lenses 222, the electronic device disclosed in the embodiment of the present application has more obvious advantages in solving the contradiction between the volume of the optical module 200 and the slimness of the electronic device.
In the electronic apparatus disclosed in the embodiment of the present application, in the case where the second lens mechanism 220 is retracted into the apparatus housing 100, the second lens mechanism 220 can be in close-fitting engagement with the first through-hole 110. In this case, the electronic device is in a state of completing shooting, and the sealing fit between the second lens mechanism 220 and the first through hole 110 at this time can isolate the outside from the internal space of the device housing 100, so as to prevent foreign matters (e.g., dust and liquid) in the air from entering the device housing 100, and especially prevent tiny particles such as dust from entering the device housing 100 after the electronic device completes shooting, thereby protecting the inside of the device housing 100.
In the electronic apparatus disclosed in the embodiment of the present application, one of the end surfaces of the first lens mechanism 210 and the second lens mechanism 220 that are butted may be provided with a positioning groove 211a, and the other one of the end surfaces of the first lens mechanism 210 and the second lens mechanism 220 that are butted may be provided with a positioning protrusion 221 a. Wherein: with at least a portion of the second lens mechanism 220 protruding out of the device housing 100 and the first lens mechanism 210 in the first position, the positioning projection 221a is in positioning engagement with the positioning groove 211 a.
Under the above circumstances, the positioning protrusion 221a and the positioning groove 211a can make the first lens mechanism 210 and the second lens mechanism 220 more closely butted, and at the same time, the first lens mechanism 210 and the second lens mechanism 220 can be precisely butted, so that the butting precision between the first lens mechanism 210 and the second lens mechanism 220 can be improved, and the shooting performance of the electronic device during shooting can be improved.
In a further embodiment, the positioning groove 211a may be an annular groove, and the positioning protrusion 221a may be an annular protrusion. Under the condition, when the positioning groove 211a and the positioning protrusion 221a help the first lens mechanism 210 and the second lens mechanism 220 to be in positioning fit, because the positioning groove 211a and the positioning protrusion 221a are both in an annular structure, the butt fit between the two can avoid the adverse effect caused by the fact that ambient light enters the lens mechanism through a butt fit gap, and further the stability of the shooting performance of the electronic device can be ensured.
In the electronic device disclosed in the embodiment of the present application, the optical module 200 may further include a module body, the module body may include a photosensitive chip 230 and a first lens mechanism 210, and the photosensitive chip 230 may convert the received optical signal into a digital signal. The first lens mechanism 210 and the photo sensor chip 230 are relatively fixed, and the first driving mechanism 300 drives the module body to drive the first lens mechanism 210 to switch between the first position and the second position. In this case, in the process of driving the first lens mechanism 210 to switch between the first position and the second position by the first driving mechanism 300, the photosensitive chip 230 also moves correspondingly along with the movement of the module body, so that the photosensitive chip 230 and the first lens mechanism 210 maintain a certain relative position relationship, thereby facilitating the photosensitive chip 230 to play a role in the shooting state of the electronic device.
In a general case, the photo sensor chip 230 may be a CCD (Charge Coupled Device) Device or a CMOS (Complementary Metal Oxide Semiconductor) Device, and the specific type of the photo sensor chip 230 is not limited in this embodiment.
In a further aspect, the device housing 100 may be provided with a first light-transmitting region 120, and the first lens mechanism 210 is disposed opposite to the first light-transmitting region 120 in a state where the first lens mechanism 210 is located at the second position. In this case, the first lens mechanism 210 is separated from the second lens mechanism 220, the height of the optical module 200 is small, and the first light-transmitting area 120 is disposed opposite to the first lens mechanism 210, so that the first lens mechanism 210 can also realize the shooting function of the electronic device at the second position, thereby increasing the shooting modes of the electronic device, and enabling the multiple shooting modes to meet the various use requirements of the user.
In the electronic device disclosed in the embodiment of the application, the second driving mechanism 400 may include a second driving motor 410, a second lead screw bracket 420, a second lead screw 430 and a second connecting member 440, the second connecting member 440 has a second threaded hole, the second lead screw bracket 420 is fixed inside the device housing 100, the second lead screw 430 is rotatably disposed on the second lead screw bracket 420, the second lead screw 430 is in threaded fit with the second threaded hole, the second connecting member 440 is fixedly connected with the second lens mechanism 220, the second connecting member 440 is in limited fit with the second lead screw bracket 420 in the rotating direction of the second lead screw 430, the second driving motor 410 is disposed inside the device housing 100, and the second driving motor 410 is drivingly connected with the second lead screw 430.
In this case, when the electronic device needs to perform a shooting function, the second driving mechanism 400 drives the second lens mechanism 220 to at least partially extend out of the device housing 100, in a more specific embodiment, the second driving motor 410 in the second driving mechanism 400 firstly transmits the driving force to the second lead screw 430 connected thereto, and the second lead screw 430 can transmit the driving force to the second connecting member 440 in threaded engagement therewith, and at this time, the second lead screw bracket 420 can support the second lead screw 430 and the second connecting member 440 sleeved on the second lead screw bracket 420.
Meanwhile, the second lead screw 430 is driven by a driving force, so that the second lead screw 430 can rotate towards one direction, the second connecting piece 440 in threaded fit with the second lead screw 430 can move along the axis direction of the second lead screw 430, the second lens mechanism 220 fixedly connected with the second connecting piece 440 can also move along with the second connecting piece 440, the driving is realized through threaded fit, and the driving is realized due to the good continuity, so that the second driving mechanism 400 can drive the second lens mechanism 220 to at least partially extend out of the equipment shell 100, and further the shooting function of the electronic equipment is realized.
The second connecting member 440 is in a limit fit with the second lead screw bracket 420 in the rotation direction of the second lead screw 430, so that the second connecting member 440 cannot rotate along with the rotation of the second lead screw 430 but can move along the axial direction of the second lead screw 430 when the second lead screw 430 rotates.
In a further aspect, the second driving mechanism 400 may be disposed within the apparatus housing 100 and located at one side of the optical axis of the second lens mechanism 220. In this case, the second driving mechanism 400 is located at one side of the optical axis of the second lens mechanism 220, and due to the connection relationship of the second connection member 440 and the second lens mechanism 220, a certain distance is provided between the second driving mechanism 400 and the second lens mechanism 220, so that the second driving mechanism 400 can reduce the probability of interfering with the movement of the second lens mechanism 220, and the layout of other components in the apparatus housing 100 can be facilitated.
In a more preferred embodiment, when the second lens mechanism 220 is located in the retracted position and the first lens mechanism 210 is located in the second position, the first lens mechanism 210 is located on a first side of the second lens mechanism 220, the second driving mechanism 400 is located on a second side of the second lens mechanism 220, and the first side and the second side are opposite sides of the second lens mechanism 220. In this case, when the electronic device finishes shooting, the first lens mechanism 210 and the second driving mechanism 400 are respectively located on two opposite sides of the second lens mechanism 220, so that the first lens mechanism 210, the second lens mechanism 220 and the second driving mechanism 400 at this time can be arranged based on the same height in the thickness direction of the electronic device, and therefore the spatial layout in the device housing 100 can be optimized, and finally the electronic device can be favorably thinned and developed.

In this case, the second connector 440 can move the second lens mechanism 220 out of the device housing 100 to a greater extent during the movement process, thereby facilitating the second lens mechanism 220 to realize the shooting function of the electronic device.
In an alternative embodiment, the second driving mechanism 400 may further include a first bevel gear 450 and a second bevel gear 460, the first bevel gear 450 is connected to the second driving motor 410, the second bevel gear 460 is coaxially fixed to the second lead screw 430, and the first bevel gear 450 and the second bevel gear 460 are engaged. In this case, during the process of driving the second lens mechanism 220 by the second driving mechanism 400, the axial directions of the first bevel gear 450 and the second bevel gear 460 may be perpendicular to each other, and the first bevel gear 450 and the second bevel gear 460 may be in tooth-meshing via a bevel tooth surface, so that the power direction from the first bevel gear 450 to the second bevel gear 460 may be changed, that is, the power direction may be changed from the first direction to the second direction, and further, the second driving mechanism is arranged to avoid occupying more space in one direction, thereby facilitating the arrangement of other components in the device housing 100. It should be noted that the first direction intersects the second direction, and specifically, the first direction and the second direction may be perpendicular to each other.
In a further aspect, the second driving mechanism 400 may further include a second speed reducer 470, and the second driving motor 410 is connected to the second bevel gear 460 through the second speed reducer 470. The second decelerator 470 can decrease the speed of the second driving motor 410 connected thereto and increase the torque, and then transmit the torque to the second bevel gear 460, so that the driving speed of the second driving motor 410 can be controlled and at the same time, a larger torque can be transmitted to the second bevel gear 460, thereby increasing the load capacity of the second bevel gear 460 under the same condition, and facilitating the subsequent driving of the second lens mechanism 220 for movement.
