In some embodiments, the fourth light inlet channel 74 may intersect the first light inlet channel 71, and the second dimming component may be disposed at a position where the fourth light inlet channel 74 intersects the first light inlet channel 71. Thus, when the first dimming component 60 is in the first dimming state, the light passing through the first dimming component 60 enters the first light inlet channel 71 and can pass through the second dimming component 68, and the second dimming component 68 can change the state to enable the light to irradiate the first photosensitive chip 40 or enter the fourth light inlet channel 74, so that the conversion of different focal lengths can be realized.

Referring to fig. 1-4, camera assembly 100 may further include at least one lens assembly 80, lens assembly 80 being disposed within light intake passage 70. The lens assembly 80 may have a plurality of lenses, and the lens assembly 80 may ensure that light rays are effectively converged, thereby ensuring an imaging effect of the camera assembly 100.
For example, the lens assembly 80 has two lens assemblies, one of which is the first lens assembly 20 and the other of which is the second lens assembly 30. In the example of fig. 1, the first lens assembly 20 is disposed in the third light inlet channel 73, and the second lens assembly 30 is disposed in the second light inlet channel 72. In the example of fig. 2, the first lens assembly 20 is disposed on the first light inlet channel 71, and the second lens assembly 30 is disposed on the second light inlet channel 72, so as to ensure the convergence of light rays, and further, the imaging effect of the camera assembly 100 can be good. Alternatively, referring to fig. 6, the number of the lens assemblies 80 may be three, and the lens assembly further includes a third lens assembly 81, where the third lens assembly 81 is disposed on the fourth light incoming channel 74.
In some embodiments, in conjunction with fig. 5, the first dimming component 67 can include a conductive circuit (not shown) and the film layer 62, the film layer 62 being electrically connected to the conductive circuit. When the film layer 62 is transparent, the light is emitted through the first emitting surface 65 and irradiates the first photosensitive chip 40; when the conductive circuit is powered off, the film 62 is opaque, and light irradiated from the first light inlet channel 71 to the film 62 is reflected by the first light modulating element 67, emitted through the second emitting surface 66, and then irradiated to the second light sensing chip 50. Like this, need not first subassembly 67 of adjusting luminance and rotate, can realize the switching of light path through the circular telegram of adjusting the rete 62 and the outage state, and then be favorable to camera subassembly 100's miniaturized design, simultaneously, can guarantee that the optical axis is in the level (for example, the left and right direction as shown in fig. 3) or vertical (for example, the upper and lower direction as shown in fig. 3) state all the time, improved the stability of camera subassembly 100's work. In addition, the time required for the camera assembly 100 to switch the optical path can be reduced. For example, when the conductive circuit is powered on, the film 62 transmits light, and the first dimming element 67 is in a first dimming state; when the conductive circuit is powered off, the film 62 is opaque, and the first dimming element 67 is in the second dimming state. Of course, in other examples, the light-transmitting or light-non-transmitting state of the film layer 62 may also be changed by temperature control, light control, pressure control, and the like.
Referring to fig. 3 and 4, the direction of the arrow shown in fig. 3 is the propagation path of the light when the film 62 is in the transparent state, and the direction of the arrow shown in fig. 4 is the propagation path of the light when the film 62 is in the opaque state. It should be noted that the dotted lines and arrows in fig. 3 and fig. 4 do not belong to the actual structure of the camera assembly according to the embodiment of the present invention, and are only schematic illustrations.
For example, the film layer 62 is a liquid crystal film, and the transparent or opaque state of the liquid crystal film can be controlled by controlling the on/off current of the conductive circuit. When the control circuit is in the power-on state, the liquid crystal molecules in the liquid crystal film can be in the orderly arrangement state, so that the liquid crystal film is in the light-transmitting state, i.e., the first dimming state, at this time, the light can freely penetrate through the liquid crystal film, and further the light can irradiate on the first photosensitive chip 40. When the control circuit is in the power-off state, the liquid crystal molecules inside the liquid crystal film will exhibit an irregular distribution state, and at this time, the first light adjusting assembly 67 can reflect the light so that the light enters the second channel and then irradiates the second light sensing chip 50.
In some embodiments, referring to fig. 1 in combination with fig. 3 and 5, the first dimming component 67 may further include: a second prism 63 and a third prism 64, wherein the second prism 63 is attached to one side surface of the film layer 62, and the first emergent surface 65 may be one surface of the second prism 63 facing the first photosensitive chip 40; the third prism 64 is attached to the other side surface of the film 62, and the second exit surface 66 may be a surface of the third prism 64 facing the second photosensitive chip 50. The liquid crystal film is a film layer 62 that selectively transmits light, and the second prism 63 and the third prism 64 are provided to redirect light. When the liquid crystal film is in a transparent state, the light can directly pass through the second prism 63 and the third prism 64 to irradiate the first photosensitive chip 40. When the liquid crystal film is in an opaque state, the light passing through the third prism 64 is reflected by the third prism 64, and then can irradiate the second photosensitive chip 50. In some examples, the second prism 63 may improve the parallelism of the light reflected by the third prism 64, and may effectively ensure that the light enters the second light inlet channel 72 along a vertical direction (e.g., an up-down direction as shown in fig. 3).
The second dimming component 68 may have the same structure and principle of switching the light path as the first dimming component 67. Alternatively, the second dimming component 68 may have a different structure or a different principle of switching the light path from the first dimming component 67, for example, as shown in fig. 6, the first exit surface 65 of the second dimming component 68 and the second exit surface 66 of the second dimming component 68 may be located at both the second prism 63 and the third prism 64.
In some embodiments, as shown in fig. 1-4, the angle between the reflective surface of the film 62 and the central axis of the first light inlet channel 71 is 45 ° so as to determine the optical axes of the first light inlet channel 71 and the second light inlet channel 72, thereby facilitating the light to be parallel to the optical axes of the first light inlet channel 71 and the second light inlet channel 72.
According to an embodiment of the present invention, the film layer 62, the second prism 63, and the third prism 64 are integrally formed. For example, the film 62, the second prism 63, and the third prism 64 are integrally formed after being glued at high temperature and high pressure, so as to ensure the structural reliability of the dimming assembly 60.
In the example of fig. 1 to 5, the cross sections of the second prism 63 and the third prism 64 are both in the shape of an isosceles right triangle, and the cross section of the columnar structure formed by attaching the second prism 63 and the third prism 64 is a square. The hypotenuses of the second prism 63 and the third prism 64 can be opposite to each other, so that the light can be further ensured to be parallel to the optical axis, the occurrence of the conditions of polarization, glare and the like can be avoided, and the imaging effect of the camera assembly 100 is good. Of course, in other examples, the second prism 63 and the third prism 64 may also be in a square or rectangular parallelepiped structure.
With reference to fig. 1-4, the first light incoming channel 71 is perpendicular to the second light incoming channel 72, so that the horizontal or vertical light propagation can be facilitated, and the imaging effect of the camera assembly 100 can be improved. Meanwhile, the first light inlet channel 71 may coincide with the central axis of the third light inlet channel 73 to further improve the imaging effect of the camera assembly 100
In some embodiments, the camera assembly 100 may further include a first prism 22, and the first prism 22 may be disposed in the third light inlet channel 73. The first prism 22 includes a first light-entering surface 221 and a first light-exiting surface 222, the first light-entering surface 221 may be parallel to a central axis of the first light-entering channel 71, the first light-exiting surface 222 may be perpendicular to the central axis of the first light-entering channel 71, the first light-exiting surface 222 is opposite to the first photo-sensing chip 40, and by the arrangement of the first prism 22, light may enter from the first light-entering surface 221 and exit from the first light-exiting surface 222, which may reduce the thickness of the camera assembly 100, thereby increasing the application range of the camera assembly 100, and being suitable for a long-focus camera. In the example of fig. 1, the first lens assembly 20 may be located between the first prism 22 and the first dimming assembly 67.
Of course, in other embodiments, as shown in fig. 2, the first lens assembly 20 may be located between the first photosensitive chip 40 and the first dimming assembly 67. The first lens assembly 20 can ensure that light rays can be effectively converged, and ensure the imaging effect of the camera assembly 100. For example. The central axes of the first lens assembly 20 and the first prism 22 are located on the same horizontal line to ensure that the images of the camera assembly 100 are not shifted. For example, camera assembly 100 is a periscopic camera assembly.
In some embodiments, as shown in fig. 1, the incident surface 61 may be disposed parallel to the first exit surface 65, in which case the camera assembly 100 may be a periscopic module. Of course, in other embodiments, the incident surface may be disposed perpendicular to the first exit surface 65, and the first photosensitive chip 40 and the second photosensitive chip 50 may be disposed in the same light inlet channel.
