Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Technical solutions disclosed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

As shown in fig. 1, an embodiment of the present application discloses an electronic device. The disclosed electronic device includes a device case 100 and a camera module 200, the device case 100 includes a case main body 110 and a protective lens 120 shown in fig. 10, the case main body 110 is provided with a through hole, a central axis of the through hole is a first reference axis O1 shown in fig. 10, and the camera module 200 is disposed in the device case 100.

As shown in fig. 2 and 3, the camera module 200 includes a lens 210. The optical axis of the lens 210 is a second reference axis O2, and the second reference axis O2 is disposed coaxially with the first reference axis O1. The lens 210 includes a lens barrel 211 and a first light distribution lens 212 disposed inside the lens barrel 211. The protection lens 120 is mounted at the light-entering end of the lens barrel 211 and is located in the through hole. The protective lens 120 and the first light distribution lens 212 are both disposed along the second reference axis O2.

In the above design, the protective lens 120 is a second light distribution lens that mates with the first light distribution lens 212. By mounting the protective lens 120 and the first light distribution lens 212 on the lens barrel 211, the protective lens 120 and the first light distribution lens 212 can move synchronously when the lens 210 focuses images; thus, compared with a conventional relative movement mode, the synchronous movement mode of the protective lens 120 and the first light distribution lens 212 does not generate movement interference, and further an avoidance gap between the protective lens 120 and the first light distribution lens 212 does not need to be arranged, so that the distance between the protective lens 120 and the first light distribution lens 212 is further reduced, and finally, when the electronic device is used for shooting, along with the increase of the field angle alpha required by shooting, the size of a light transmission area arranged on the device shell 100 does not change greatly, so that the occupied area of a convex hull accommodating the light transmission area is also greatly reduced, and the overall appearance performance of the electronic device is integrally improved.

In some embodiments, as shown in fig. 2 and 3, the camera module 200 further includes a photosensitive chip 220 and a driving mechanism 230. The photosensitive chip 220 is disposed inside the apparatus case 100, and the photosensitive chip 220 is disposed along the second reference axis O2 and is disposed opposite to the lens 210. As shown in fig. 10, the lens 210 is movably disposed in a through hole of the apparatus case 100 and is movable in the direction of the first reference axis O1. The protective lens 120 is synchronously movable with the lens 210 as shown in fig. 2 and 3, and a driving mechanism 230 is provided inside the apparatus case 100, the driving mechanism 230 being connected to the lens 210.

In this way, by driving the driving mechanism 230, the lens 210 can be retracted into the apparatus housing 100 when shooting is not performed and can be extended out of the apparatus housing 100 at least partially when shooting is performed, through the through hole and along the first reference axis O1, and such a telescopic manner can protect the lens 210 in a non-shooting state. Meanwhile, as shown in fig. 10, since the lens 210 needs to extend out of the device housing 100 to achieve shooting, as the extension proceeds, the height difference between the lens 210 and the lens 210 is gradually increased, so that the interference of the light-transmitting area of the device housing 100 on the lens 210 is gradually reduced to achieve a larger field angle α required for shooting, according to experimental data statistics, when the lens 210 extends out to a vertex, the maximum field angle α that can be achieved by the lens 210 exceeds 200 °, that is, the lens 210 with the larger field angle α can be loaded on the camera module 200 to achieve a larger shooting range.

In some embodiments, as shown in fig. 2, 3, and 10, camera module 200 may further include a module housing 240. The module housing 240 is fixedly installed in the equipment housing 100. The module case 240 has an insertion hole opened along the second reference axis O2. The photo sensor chip 220 is disposed in the module case 240. The driving mechanism 230 is disposed on the module housing 240. The lens 210 is movably disposed in the insertion hole of the module case 240, and can be extended or retracted with respect to the apparatus case 100 by a reciprocating motion along the second reference axis O2. In this way, the relevant components of the camera module 200, such as the lens 210 and the driving mechanism 230, can be integrated on the module housing 240, so that the camera module 200 can be integrated into a whole module to be loaded in the device housing 100, thereby facilitating the whole disassembly and replacement. Meanwhile, no matter the lens 210 is in the extended state or the retracted state, at least a part of the lens is located in the module housing 240, so that the lens and the housing are always integrated in the using process, and the lens and the housing are prevented from being separated from each other and losing efficacy.

To prevent the lens 210 from being separated from the module housing 240 during movement, the lens can be moved by providing a position-limiting member at the end positions of the extended state and the retracted state, or by the specific structure and driving manner of the driving mechanism 230. For the driving mechanism 230, there are many structures capable of achieving corresponding driving functions, for example, a pneumatic transmission or a hydraulic transmission realized by a piston mechanism, a lead screw pair transmission realized by a lead screw mechanism, a transmission mechanism of a rack and pinion structure, and the like, all of which can drive the lens 210 to extend or retract, or drive the lens 210 to extend or retract by self-shape restoration by using a shape memory alloy. One drive mechanism 230 configuration disclosed herein is shown in fig. 8 and includes a drive body 231, a rotating sleeve 232, and a mating projection 233. The fitting protrusion 233 is fixed on the lens 210, and the rotating sleeve 232 is sleeved on the lens 210. The side wall of the rotating sleeve 232 is provided with a spiral guide structure 2331. By the sliding engagement of the fitting projection 233 with the spiral guide 2331 and the driving of the rotation sleeve 232 by the driving body 231, the relative positional change between the fitting projection 233 and the rotation sleeve 232 can be realized, and the retraction movement of the lens 210 in the axial direction of the second reference axis O2, i.e., the through hole, as shown in fig. 4 and 6 and the extension movement as shown in fig. 5 and 7 can be realized in appearance.

Further, for the driving body 231, in order to drive the rotating sleeve 232 to rotate, there are many structures and connection manners that can be realized, for example, the driving body 231 is a motor, and the rotating sleeve 232 and the driving body 231 are directly connected by a shaft hub, so that the rotating sleeve 232 can rotate, or the rotating sleeve 232 can rotate by adopting a belt transmission manner, a chain transmission manner, or the like between the driving body 231 and the rotating sleeve 232. As shown in fig. 8 and 9, an alternative embodiment of the present application, the driving body 231 may include a driving motor 2311, a gear transmission 2312, and a rack gear 2313. The rack 2313 rotates along the second reference axis O2 to form an arc rack and is fixedly arranged on the peripheral wall of the rotating sleeve 232; the gear transmission mechanism 2312 is a gear set and is provided with a large gear and a small gear which are coaxially arranged; the driving motor 2311 is provided with a driving gear meshed with a large gear of the gear transmission mechanism 2312, and a small gear of the gear transmission mechanism 2312 is meshed with the rack 2313, so that the whole driving main body 231 forms a speed reducer mechanism, the driving motor 2311 transmits power to the rack 2313 in a speed reducer mode, and finally the rotation of the driving motor 2311 at a high rotating speed and a small torque is converted into the rotation of the rotating sleeve 232 at a low rotating speed and a large torque, so that the rotating sleeve 232 is ensured to be stable and effective when rotating, and the lens driving device is more suitable for the extension or retraction of the subsequent lens 210. In a further technical scheme, rack 2313 and rotating sleeve 232 formula structure as an organic whole, the both of being convenient for like this carry out whole dismouting, improve the assembling nature of equipment.

In a further embodiment, as shown in fig. 8, the plurality of matching protrusions 233 may be distributed on the periphery of the lens 210 in an annular array, and the spiral guiding structures 2331 are also distributed on the sidewall of the rotating sleeve 232 in an annular array. The spiral guide 2331 and the mating protrusion 233 are correspondingly arranged in number and position, and each corresponding spiral guide 2331 is correspondingly slidably engaged with one of the mating protrusions 233, so that the driving mechanism 230 can drive the lens 210 more smoothly in a multi-point manner.

In a specific embodiment, the spiral guide 2331 can be a spiral groove structure that is recessed in a non-penetrating manner on the inner wall of the rotating sleeve 232, so as to ensure the strength of the entire rotating sleeve 232. The spiral guide structure 2331 disclosed in the embodiments of the present application may be a spiral hole as shown in fig. 8, that is, the spiral hole is disposed on the side wall of the rotating sleeve 232 in a penetrating manner, so that the spiral guide structure 2331 and the fitting protrusion 233 can be conveniently assembled under the condition that the strength of the rotating sleeve 232 is ensured to meet the use requirement. Meanwhile, it should be noted that, for the spiral guide 2331, whether made as a spiral hole or a spiral groove, the length and the spiral angle thereof can be used to comprehensively determine the stroke of the fitting protrusion 233 along the second reference axis O2, so as to control the extending amount and the retracting amount of the lens 210 relative to the apparatus housing 100, and thus control the apparatus more precisely.

In some embodiments, as shown in fig. 2 and 3, by the irradiation of the ambient light, the lens 210 will form an image plane, and the photo-sensing chip 220 will form a photo-sensing plane, both of which are perpendicular to the optical axis of the lens 210, i.e. perpendicular to the second reference axis O2, then the present application controls the imaging of the lens 210 as follows:

when the lens 210 is required to perform shooting and imaging, the lens 210 is extended out of the device housing 100 as shown in fig. 2, so that the imaging surface and the photosensitive surface are overlapped; when the lens 210 is retracted into the apparatus housing 100 as shown in fig. 3, the image plane and the light-sensing plane will no longer coincide, and specifically, the image plane and the light-sensing plane will form a space in the direction of the second reference axis O2, by which the lens 210 is prevented from taking an image. By the arrangement mode, the electronic device can be prevented from entering an abnormal shooting state through some intelligent programs loaded on the electronic device, for example, when the electronic device is a smart phone, if the application programs loaded on the electronic device contain trojans and the like, the lens 210 can be prevented from shooting by keeping a retraction state, so that the privacy of a user is protected, once the lens 210 is started abnormally, the non-artificial extension state of the lens can be timely known by the user, and the privacy of the user is further protected.

In some embodiments, the protection lens 120 shown in fig. 2 and 3 may be an ultra-wide-angle fisheye lens, and the camera module 200 may be an ultra-wide-angle camera module, which are arranged in such a way that the lens 210 can reach a wider field angle α when extending out of the device housing 100 as shown in fig. 10, thereby further increasing the shooting range of the electronic device.

The electronic device disclosed in the embodiment of the present application may be a mobile phone, a tablet computer, an electronic book reader, a wearable device (e.g., smart glasses, a smart watch, etc.), a game console, or may be other types of devices, and the embodiment of the present application does not limit the specific types of the electronic device.

In the embodiments of the present application, the difference between the embodiments is described in detail, and different optimization features between the embodiments can be combined to form a better embodiment as long as the differences are not contradictory, and further description is omitted here in view of brevity of the text.

The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
