Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, 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 invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 5, an embodiment of the invention discloses a prism structure, which is suitable for adjusting an optical path. The disclosed prismatic structure includes a first support 500.
The first support 500 is a hollow structure, that is, light can be transmitted without being blocked inside the first support 500. Meanwhile, the first support 500 has a first light path outlet 510, a second light path outlet 520, a first light path inlet 530, and a second light path inlet 540, the first light path inlet 530 corresponding to the first light path outlet 510, and the second light path inlet 540 corresponding to the second light path outlet 520. Specifically, external light may enter the inside of the first support 500 from the first and second light path inlets 530 and 540, and light entering from the first light path inlet 530 may be emitted from the first light path outlet 510, and light entering from the second light path inlet 540 may be emitted from the second light path outlet 520; thus, two independent optical paths are formed on the first support 500, and different optical path propagation paths are different, so that different focal length ranges can be formed when the imaging technology is applied.
The first bracket 500 has a rotation axis about which the first bracket 500 is rotatable, and the first and second light path outlets 510 and 520 are located in a circumferential direction of the rotation axis. It should be understood that when the first support 500 rotates around its rotation axis, the first optical path outlet 510 and the second optical path outlet 520 also rotate around the rotation axis, so that the positions of the first optical path outlet 510 and the second optical path outlet 520 can be selectively changed, thereby realizing the switching of different optical paths.
Of course, the present embodiment does not limit the specific shape type of the first support 500, and as shown in fig. 2, the first support 500 may be a polyhedron, which may also be a cylinder, a sphere, etc. Further, the first bracket 500 may further include more optical path inlets and optical path outlets combined to form more optical paths, which can cover a larger focal range when applied to the image capture technology.
As can be seen from the above description, in the prism structure disclosed in the embodiment of the present invention, the prism structure includes the first bracket 500, the first bracket 500 is a hollow structural member, and the first bracket 500 has the first light path outlet 510, the second light path outlet 520, the first light path inlet 530 and the second light path inlet 540, because the first light path inlet 530 corresponds to the first light path outlet 510, and the second light path inlet 540 corresponds to the second light path outlet 520, the prism structure can form two independent light paths, and further can increase the selectable range of the focal length; meanwhile, the first carriage 500 can rotate about its rotation axis, and thus can be selectively switched between two optical paths.
When the prism structure disclosed by the embodiment of the invention is applied to the cameras and the electronic equipment, the function of two cameras can be realized based on the switching of the prism structure to the light path, and only one set of photosensitive element, anti-shake module and other devices are required to be equipped correspondingly.
In an alternative scheme, the first light path inlet 530 may be provided with a first light inlet prism 531, the first light path outlet 510 may be provided with a first light outlet prism 511, the second light path inlet 540 may be provided with a second light inlet prism 541, and the second light path outlet 520 may be provided with a second light outlet prism 521. Under such a configuration, when external light enters the first bracket 500 from the first light path inlet 530 and the second light path inlet 540, the external light needs to be transmitted through the first light-entering prism 531 and the second light-entering prism 541, respectively, and the external light exits from the first light path outlet 510 and the second light path outlet 520 to the outside of the first bracket 500, the external light needs to be transmitted through the first light-exiting prism 511 and the second light-exiting prism 521, respectively; in the above process, the first light-entering prism 531, the second light-entering prism 541, the first light-exiting prism 511, and the second light-exiting prism 521 can all adjust the light path of the light, and generally play a role of converging the light (i.e., the first light-entering prism 531, the second light-entering prism 541, the first light-exiting prism 511, and the second light-exiting prism 521 are in a converging configuration, but they may also be in a diverging configuration), so as to achieve the optimal adjustment of the focal length; meanwhile, the first light entering prism 531, the second light entering prism 541, the first light exiting prism 511 and the second light exiting prism 521 may also have other filtering functions, for example, infrared light may be filtered out to avoid the infrared light from affecting the imaging effect.
The specific arrangement of the first light entering prism 531, the second light entering prism 541, the first light exiting prism 511 and the second light exiting prism 521 on the first bracket 500 is not limited in this embodiment, and may be determined according to the actual application environment.
In an alternative scheme, the prism structure may further include a first reflecting element group, the first reflecting element group is disposed in the first bracket 500, and the first reflecting element group reflects the light entering from the first light path inlet 530 to the first light path outlet 510. As described above, different optical paths formed in the first bracket 500 need to include different focal length ranges, and the first reflecting element group can reflect the light from the first optical path inlet 530 and then project the light to the first optical path outlet 510, thereby undoubtedly increasing the path length of the optical path and increasing the focal length range compared with the case where the light is directly incident from the first optical path inlet 530 and then exits from the first optical path outlet 510. It will be appreciated that the optical path processed by the first set of reflecting elements performs the function of a telephoto lens, whereas the optical path not processed by the set of reflecting elements performs the function of a short-focus lens.
In this embodiment, the first reflecting element group may be configured in various ways, and in a specific embodiment, the first reflecting element group may include a first reflecting element 610 and a second reflecting element 620, and light entering from the first optical path inlet 530 passes through the first reflecting element 610 and the second reflecting element 620 in sequence and is reflected to the first optical path outlet 510. It should be understood that the first reflecting member 610 may be disposed opposite to the first light path inlet 530 so that external light can be projected onto the first reflecting member 610 after being injected into the first supporter 500 from the first light path inlet 530; the first reflective element 610 may be disposed opposite to the second reflective element 620, so that the light reflected by the first reflective element 610 can be projected onto the second reflective element 620; the second reflecting element 620 may be disposed opposite to the first light path outlet 510, so that the light reflected by the second reflecting element 620 can be projected to the first light path outlet 510 and projected to the outside of the first bracket 500.
Of course, the configuration of the first reflection element group is not limited in this embodiment, for example, the first reflection element group may also include only one mirror, and the light is reflected once inside the first bracket 500, i.e., projected outside the first bracket 500 through the first light path outlet 510.
Typically, the first reflective element 610 and the second reflective element 620 can both be planar mirrors. The present embodiment does not limit the specific types of the first and second reflecting elements 610 and 620, for example, both may be reflecting prisms.
In combination with the above, the first bracket 500 is a main body member of a prism structure, and provides a mounting base for the first light entering prism 531, the second light entering prism 541, the first light exiting prism 511, the second light exiting prism 521, and the first reflecting element group.
Referring to fig. 1 to 5 again, based on the prism structure, the embodiment of the invention further discloses an optical module, which can be of various types, and can be a camera module generally. The optical module disclosed in the embodiment of the present invention includes the photosensitive element 200, the first driving mechanism 800 and the prism structure.
The photosensitive element 200 is an imaging member of an optical module, which can convert light into a picture, i.e., form an image after being photosensitive. In the present embodiment, the external light can be projected onto the photosensitive element 200 through the prism structure, so as to form an image smoothly. In general, the photosensitive element 200 can be a CMOS photosensitive chip. Based on the effect of the prism structure, the photosensitive element 200 can image light rays on different light paths, i.e. in different focal length ranges, on the prism structure.
As described above, the first bracket 500 may rotate, and in the present embodiment, the first bracket 500 may rotate based on the first driving mechanism 800. Specifically, the first driving mechanism 800 is connected to the first bracket 500, and the first driving mechanism 800 drives the first bracket 500 to rotate around the rotation axis to perform selective switching on different optical paths.
The first bracket 500 has a first state and a second state, and the first bracket 500 can switch the states during rotation; wherein the first optical path outlet 510 is opposite to the light sensing element 200 in the first state, and the second optical path outlet 520 is opposite to the light sensing element 200 in the second state. Specifically, when the first bracket 500 is in the first state, the light sensing element 200 may receive and sense light propagating through the first light path, that is, light incident from the first light path inlet 530 and exiting from the first light path outlet 510; when the first bracket 500 is in the second state, the light sensing element 200 may receive and sense the light transmitted through the second light path, i.e., the light incident from the second light path inlet 540 and exiting from the second light path outlet 520.
Because the focal length ranges of the light rays of the two light paths are different, the functions of the two cameras are equivalently realized, and only one photosensitive element is used, so that the configuration number of the cameras, the photosensitive element and the like can be reduced compared with the prior art, and the beneficial effects of reducing the manufacturing cost and optimizing the structural layout inside the electronic equipment are further realized.
In this embodiment, the specific type of the first driving mechanism 800 may be various. In a specific embodiment, the first driving mechanism 800 may include a second bracket 810, a transmission shaft 820 and a coil 830, the second bracket 810 is provided with a rotation matching portion 811, the rotation matching portion 811 has a rotation slot, one end of the transmission shaft 820 is connected to the first bracket 500, the other end of the transmission shaft 820 is rotatably matched with the rotation matching portion 811 through the rotation slot, the transmission shaft 820 is a permanent magnet, and the coil 830 is disposed on the second bracket 810.
Specifically, when the coil 830 is energized, a magnetic field is generated around the coil 830 based on a magnetic effect of the current, and the magnetic field interacts with (attracts or repels) the magnetic field of the transmission shaft 820 to drive the transmission shaft 820 to rotate in the rotation slot, and the first bracket 500 rotates along with the transmission shaft 820 and is switched between the first state and the second state. It should be noted that the rotation of the magnet by energizing the coil is a conventional means in the art, and is not described herein.
In order to improve the rotational stability and the installation reliability of the transmission shaft 820, in an alternative, the second end of the transmission shaft 820 is provided with a limit protrusion 821 along the circumferential direction, and the limit protrusion 821 is rotatably fitted to the rotation groove. It should be understood that the limiting convex part 821 can be clamped in the limiting groove on the basis of the rotation fit of the transmission shaft 820 and the rotation groove of the rotation fitting part 811, thereby preventing the transmission shaft 820 from being separated from the rotation fitting part 811. Thus, the transmission shaft 820 can be reliably installed in the rotation groove and can realize stable rotation, thereby ensuring that the first bracket 500 can smoothly realize state switching.
Further, the rotation fitting portion 811 may be a magnetic structure. With such a configuration, the magnetic field intensity around the transmission shaft 820 is increased, so as to improve the driving efficiency of the transmission shaft 820, and further improve the working efficiency of the first driving mechanism 800 driving the first bracket 500. Of course, the present embodiment does not limit the specific material for manufacturing the rotation fitting portion 811, and it may be a non-magnetic structural member.
In general, the optical module may further include a first housing 100, the first housing 100 being a base member of the optical module and providing a mounting base for the prism structure, the photosensitive element 200, the first driving mechanism 800, and the like, the first housing 100 generally having an inner cavity 110, and the prism structure, the photosensitive element 200, the first driving mechanism 800, and the like being generally disposed in the inner cavity 110.
The first housing 100 has a first light transmission portion 120 and a second light transmission portion 130, and the first light transmission portion 120 and the second light transmission portion 130 communicate with the inner cavity 110. It should be understood that the first and second light-transmitting portions 120 and 130 can allow external light to be injected into the inner cavity 110, providing for subsequent prism structures to adjust the light path of the light and for the light sensing of the light-sensing element 200. Specifically, the first light-transmitting portion 120 and the second light-transmitting portion 130 may include a mounting hole opened on the housing and a light-transmitting cover plate disposed in the mounting hole, and the light-transmitting cover plate may perform a certain protection function. The transparent cover may be made of transparent resin or glass, for example, the first transparent portion 120 may include a first protective mirror 121, the second transparent portion 130 may include a second protective mirror 131, and the first protective mirror 121 and the second protective mirror 131 are transparent covers.
Of course, the specific types of the first light transmission portion 120 and the second light transmission portion 130 are not limited in this embodiment, and the light transmission portions may also be directly configured as light transmission holes, but this method is not favorable for the waterproof and dustproof performance of the optical module.
In correspondence to the above, when the first bracket 500 is in the first state, the first bracket 500 rotates to allow the light entering from the first light-transmitting portion 120 to be projected to the first light path inlet 530, and when the first bracket 500 is in the second state, the first bracket 500 rotates to allow the light entering from the second light-transmitting portion 130 to be projected to the second light path inlet 540.
In this embodiment, the specific matching relationship between the first light-transmitting portion 120 and the first light path inlet 530 and the specific matching relationship between the second light-transmitting portion 130 and the second light path inlet 540 are not limited, for example, the first light-transmitting portion 120 and the first light path inlet 530 may be disposed oppositely, and the second light-transmitting portion 130 and the second light path inlet 540 may also be disposed oppositely.
In another specific embodiment, the optical module may further include a second reflective element group, the second reflective element group is disposed in the inner cavity 110, and in the second state, the second reflective element group reflects the light passing through the second light-transmitting portion 130 to the second light path inlet 540. It should be understood that, when the first bracket 500 is in the second state, the light entering from the second light-transmitting portion 130 is projected to the second light path inlet 540 through the second reflecting element group; based on the second reflecting element group, the optical path length of the light rays from the second optical path inlet 540 and sensed on the light sensing element 200 can be increased, and the focal range is increased.
It should be noted that the second reflective element group and the first reflective element group can not only increase the focal length coverage of the optical module, but also optimize the position layout of the first light-transmitting portion 120 and the second light-transmitting portion 130. Specifically, in the present embodiment, the optical module only uses one photosensitive element 200, and the first transparent portion 120 and the second transparent portion 130 can be disposed in any direction of the housing 100, and finally, external light can be projected onto the photosensitive element 200 through the first reflective element group and the second reflective element group to form an image smoothly.
In this embodiment, the second reflective element group may be configured in various ways, and in a specific embodiment, the second reflective element group may be a third reflective element 710, the third reflective element 710 has a reflective surface 711, and the reflective surface 711 is opposite to the second transparent portion 130; in the second state, the reflection surface 711 is opposed to the second light path inlet 540. It should be understood that when the first bracket 500 is in the second state, external light entering the inner cavity 110 from the second light-transmitting portion 130 may be projected onto the reflecting surface 711 and reflected to the second light path inlet 540 via the reflecting surface 711.
In the embodiment, the third reflective element 710 can be a reflective prism, but it can also be other reflective structures such as a plane mirror. Of course, the present embodiment also does not limit the configuration of the second reflective element group, and it may also include a plurality of mirrors, so that the external light enters the inner cavity 110 from the second light-transmitting portion 130, and then is reflected for a plurality of times and then projected to the second light path inlet 540.
In order to further optimize the focal length adjustment effect of the optical module on light, in an optional scheme, the optical module may further include a first focusing lens group 300 and a second focusing lens group 400, the first focusing lens group 300 is located between the photosensitive element 200 and the prism structure, the second focusing lens group 400 is disposed on a side of the prism structure away from the first focusing lens group 300, and optical axes of the first focusing lens group 300 and the second focusing lens group 400 both pass through the photosensitive element 200.
It should be understood that the first focusing lens assembly 300 and the second focusing lens assembly 400 are generally lens structures, and can converge or diverge light to adjust the focal length of the optical module, and they are generally in a converging configuration, so that the light can be converged to facilitate imaging by the photosensitive element 200; the embodiment does not limit the first focusing lens group 300 and the second focusing lens group 400 to be a convex lens or a concave lens.
In this embodiment, the optical module may further include a second driving mechanism, which is connected to the first focusing lens assembly 300 and can drive the first focusing lens assembly 300 to move along the optical axis direction thereof, so as to implement stepless zooming of the optical module. The embodiment is not limited to a specific type of the second driving mechanism, and may be a focus motor, or other hydraulic telescopic members, a screw mechanism, or the like.
Based on the prism structure or the optical module, an embodiment of the invention further discloses an electronic device, which comprises the prism structure or the optical module. The electronic device in the embodiment of the present invention may be a smart phone, a tablet computer, an electronic book reader, a wearable device, or other devices, and the embodiment of the present invention does not limit the specific type of the electronic device.
In the electronic device, the light sensing element 200 generally includes a sensor body 210 and a second housing 220, the sensor body 210 is disposed on the second housing 220, and the sensor body 210 is generally electrically connected to a main board of the electronic device through a flexible circuit board to implement power supply and information interaction.
In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.
