Description

Technical Field

[0001] The present application relates to the technical field of cameras, and in particular to a camera module and an intelligent interactive device. Background Art

[0002] At present, most intelligent interactive devices are equipped with camera modules to meet the needs of video and shooting. The horizontal field of view of existing camera modules is relatively limited, generally between 20° and 60°. In optical instruments (such as camera modules), the angle formed by the two edges of the maximum range of the lens through which the image of the measured target can pass is called the field of view. The size of the field of view determines the field of view of the optical instrument, that is, the larger the field of view, the larger the field of view and the smaller the optical magnification. In layman's terms, if the target object exceeds the field of view, it will not be included in the lens. Therefore, the smaller field of view range greatly limits the shooting ability of the camera module.

[0003] In response to the above problems, related technologies generally require designing multiple lenses in front of the camera module to obtain a large horizontal field of view, and to enlarge the field of view by continuously refracting the light path. However, the optical path structure design of this solution is relatively complex and requires high lens mold costs. In addition, there is also a method of splicing multiple camera modules, which still has shortcomings such as high equipment investment cost, complex structure, and large installation space. Summary of the invention

[0008] When the camera module of the above scheme is used, the reflective surface of the reflector is arranged facing the real scene, and then the camera assembly and the reflector are arranged obliquely opposite to each other to avoid blocking the light path of the camera assembly. At this time, since the lens of the camera assembly is arranged opposite to the arc-shaped convex surface of the reflector, the arc-shaped convex surface has a reflective expansion effect on the light path of the lens, that is, the light path will expand outward after being reflected by the arc-shaped convex surface, which effectively enlarges the horizontal field of view angle, thereby improving the field of view and shooting ability of the camera module. Compared with the prior art, the camera module of this scheme has a simple structure, low equipment investment cost, small installation space and strong feasibility.

[0012] In one of the embodiments, the camera module further includes a shell, the reflector is movably disposed on the inner wall of the shell, the camera assembly is fixed to the inner wall of the shell, and the relative position and angle between the camera assembly and the reflector are adjustable.

[0016] In one of the embodiments, the camera module further includes a second driving component, which is drivingly connected to at least one of the arc-shaped support bodies; alternatively, the arc-shaped support body can be rotated manually.

[0017] In one embodiment, the camera module further includes a lens cover, the housing is provided with a shooting window, and the lens cover is provided at the shooting window;

[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0034] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0035] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0036] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0037] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0039] The size of the field of view angle determines the field of view of the optical instrument, that is, the larger the field of view angle, the larger the field of view and the smaller the optical magnification. In layman's terms, if the target object exceeds the field of view angle, it will not be captured by the lens 21. Therefore, the smaller field of view angle range greatly limits the shooting capability of the camera module 100.

[0040] In the related art, in order to obtain a large horizontal field of view, it is generally necessary to design multiple lenses in front of the camera module 100 to enlarge the field of view by continuously refracting the light path. However, the optical path structure design of this solution is relatively complex and requires high lens mold costs. In addition, there is also a method of splicing multiple camera modules 100, which still has the disadvantages of high equipment investment cost, complex structure, and large installation space. In order to effectively solve the above problems, the present application proposes a camera module 100 with a new structural form.

[0041] For example, please refer to Figures 1 to Figure 4 , is a schematic diagram showing a structure of a camera module 100 according to an embodiment of the present application. The camera module 100 includes a reflector 10 and a camera assembly 20 .

[0042] The reflector 10 is provided with a reflective surface, and the reflective surface is formed as an arc-shaped convex surface 11, and the arc-shaped convex surface 11 is used to face the real scene. It can be understood that the reflector 10 can be an entire arc-shaped structure, so that the reflective surface is formed as an arc-shaped convex surface 11, and the side of the reflector 10 opposite to the arc-shaped convex surface 11 is an arc-shaped concave surface; of course, the reflector 10 can also be designed as an arc-shaped convex surface 11 on the side facing the real scene, and the specific selection can be made according to actual needs.

[0043] The reflector 10 in this case may refer to a glass mirror, or may refer to an object made of other materials with an optical reflective surface.

[0044] In addition, the camera assembly 20 is arranged obliquely opposite to the reflector 10, and the camera assembly 20 includes a lens 21, which is arranged facing the reflective surface.

[0045] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: when the camera module 100 of the above solution is used, the reflective surface of the reflector 10 is arranged to face the real scene, and then the camera assembly 20 and the reflector 10 are arranged obliquely opposite to each other to avoid blocking the light path of the camera assembly 20. At this time, since the lens 21 of the camera assembly 20 is arranged opposite to the arc-shaped convex surface 11 of the reflector 10, the arc-shaped convex surface 11 has a reflective expansion effect on the light path of the lens 21, that is, the light path will expand outward after being reflected by the arc-shaped convex surface 11, which effectively enlarges the horizontal field of view angle, thereby improving the field of view and shooting capability of the camera module 100, and compared with the prior art, the camera module 100 of this solution has a simple structure, low equipment investment cost, small installation space and strong feasibility.

[0046] Horizontal field of view can be referred to Figure 5 Understand from angle A.

[0047] Based on the above embodiments, the reflector 10 in the present application is a rectangular plate structure, and the reflector 10 has a first direction and a second direction. Specifically, the first direction corresponds to the width direction of the reflector 10, and the first direction is in the horizontal direction; the second direction corresponds to the length direction of the reflector 10, and the second direction is in the vertical direction.

[0048] The reflector 10 is curved in a first direction to form an arc-shaped convex surface 11 , and the camera assembly 20 is arranged obliquely opposite to one end of the reflector 10 in a second direction.

[0049] After such a structural arrangement, the arc-shaped convex surface 11 arranged in the horizontal direction can magnify the optical path of the lens 21 in the horizontal direction, thereby expanding the horizontal field of view of the camera module 100. And because the camera assembly 20 is arranged at one end of the length direction of the reflector 10, it can avoid blocking the vertical field of view.

[0050] Specifically, the first direction corresponds to the S1 direction in FIG. 1 , and the second direction corresponds to the S2 direction in FIG. 1 .

[0051] Please continue to refer to Figures 2 to Figure 4 Furthermore, in some optional embodiments, the camera module 100 also includes a shell 30, the reflector 10 is fixed to the inner wall of the shell 30, the camera assembly 20 can be movably arranged on the inner wall of the shell 30, and the relative position and angle between the camera assembly 20 and the reflector 10 are adjustable.

[0052] The shell 30 is used to load and fix the reflector 10 and the camera assembly 20 to maintain the relative posture of the reflector 10 and the camera assembly 20 stable and ensure reliable operation. It also protects the reflector 10 and the camera assembly 20 to avoid direct exposure to the environment and easy contamination by dust and other stains that affect the shooting effect.

[0053] In addition, since the camera assembly 20 is movable, the relative position and angle between the camera assembly 20 and the reflector 10 can be flexibly adjusted, so that the shooting angle and horizontal field angle of the camera assembly 20 can be flexibly changed, so that the camera module 100 obtains different shooting parameters to meet different shooting needs.

[0054] Optionally, the camera assembly 20 can be rotatably mounted on the inner wall of the shell 30 using hinges, hinges, universal bearings and other components, or can be slidably mounted on the inner wall of the shell 30 using straight and / or arc slide rail assemblies, depending on actual needs.

[0055] Of course, as an alternative to the above embodiment, in some other optional embodiments, the camera module 100 further includes a housing 30, the reflector 10 is movably disposed on the inner wall of the housing 30, the camera assembly 20 is fixedly disposed on the inner wall of the housing 30, and the relative position and angle between the camera assembly 20 and the reflector 10 are adjustable. This embodiment can achieve substantially the same technical effect as the above embodiment, so it will not be described in detail here, and can be understood by referring to the above.

[0056] It is necessary to explain that the curvature of the curved convex surface 11 of the reflector 10 has an effect on the horizontal field of view angle of the camera assembly 20, that is, by adjusting the curvature of the curved convex surface 11, the purpose of adjusting the magnification effect of the horizontal field of view angle can be achieved. Specifically, when the curved convex surface 11 is closer to a plane, that is, the curvature of the convex raised part is closer to 180°, the magnification effect of the horizontal field of view angle is smaller; conversely, the magnification effect of the horizontal field of view angle is greater.

[0057] For example, in Figures 1 and Figure 6 The reflectors 10 shown in the figure are all fixed reflectors, that is, the reflectors 10 have a fixed structural form, so that the arc-shaped convex surface 11 has only one specific arc size.

[0058] In order to achieve the above-mentioned adjustable horizontal field of view, please continue to refer to Figure 7 In some optional embodiments, the reflector 10 includes at least two split mirrors, at least two split mirrors are arranged in the same plane, and two adjacent split mirrors are located on the sides of the arc direction of the arc-shaped convex surface 11 and are rotatably connected by a rotating component 60, and the mirror surfaces of all the split mirrors are spliced ​​to form a reflecting surface.

[0059] At this time, the reflector 10 is formed into a flexible reflector. When each split mirror rotates in the flat direction, each split mirror can be closer to being in the same plane. At this time, the curvature of the arc-shaped convex surface 11 will become smaller, thereby achieving the effect of enlarging the horizontal field of view angle; on the contrary, when the each split mirror rotates and converges, the curvature of the arc-shaped convex surface 11 will become larger, thereby achieving the effect of reducing the horizontal field of view angle.

[0060] For example, the rotating assembly 60 may be a multi-axis hinge or the like.

[0061] Furthermore, the camera module 100 further includes a first driving component, which is drivingly connected to at least one split mirror; or the split mirror can be rotated manually. When rotating and adjusting the split mirror, the first driving component can be selected to automatically drive the split mirror to rotate according to actual needs, or the split mirror can be manually flipped to meet different operation requirements.

[0062] In other optional embodiments, the reflector 10 includes a reflective medium layer and at least two arc-shaped support bodies, at least two arc-shaped support bodies are arranged in the same plane, and two adjacent arc-shaped support bodies are located on the sides of the arc-shaped convex surface 11 and are rotatably connected by a rotating component 60, and the reflective medium layer is covered on the same surface of all the arc-shaped support bodies, and the surface of the reflective medium layer facing away from the arc-shaped support body constitutes a reflecting surface.

[0063] The difference between this embodiment and the above-mentioned reflector 10 composed of at least two split mirrors is that the arcuate convex surface 11 is formed by the surface of the reflective medium layer which is an integral structure and covers the surface of at least two arcuate support bodies. The arcuate support body is only used to support the reflective medium layer, and by rotating the arcuate support body and changing the supporting area of ​​the arcuate support body on the reflective medium layer, the curvature of the arcuate convex surface 11 can be adjusted, thereby achieving the purpose of adjusting the horizontal field of view. And because the reflective medium layer is an integral structure, the existence of gaps is avoided, which can prevent interference with the reflection effect of the light path.

[0064] Optionally, the reflective medium layer may be a film, a plate, etc. with a reflective mirror surface, which may be selected according to actual needs.

[0065] Furthermore, the camera module 100 further includes a second driving component, which is drivingly connected to at least one arc-shaped support body; or the arc-shaped support body can be rotated manually. Similarly, the rotation of the arc-shaped support body can be automatically driven by installing the second driving component, or can be realized by manual rotation, so as to meet different usage requirements.

[0066] Optionally, the first driving component may be a driving device that can directly output rotational power, or may be a driving device that can convert output linear power into rotational power.

[0067] Please continue to refer to FIG. 2. In addition, the camera module 100 further includes a lens cover 40. The housing 30 is provided with a shooting window, and the lens cover 40 is provided at the shooting window. The lens cover 40 is used to close the shooting window, so that the camera assembly 20 can shoot normally and can also prevent dust in the external environment from being contaminated on the surface of the lens 21. The housing 30 is provided with a wire outlet hole, and the connecting wire 50 of the camera assembly 20 passes through the wire outlet hole to the outside of the housing 30. This facilitates wiring to achieve electrical connection of the camera assembly 20.

[0068] In the present application, the camera assembly 20 is a standard camera assembly 20 product, and therefore, in addition to the lens 21 , it also includes components such as a sensor, a filter, and a lens 21 bracket.

[0069] In addition to the above, the present application further proposes an intelligent interactive device, which includes a device body and a camera module 100 as described in any of the above embodiments, and the camera module 100 is installed on the device body.

[0070] For example, the intelligent interactive device may be, but is not limited to, a tablet, an all-in-one learning machine, a conference screen, etc.

[0071] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
