Description

Periscopic camera module and electronic equipment

Technical Field

The application relates to the field of electronic equipment, in particular to periscopic camera module and electronic equipment.

Background

Periscopic camera module mainly includes: the device comprises a light-transmitting mirror, a reflector, a focusing mirror assembly, a focusing motor and a sensor, and mainly utilizes a periscopic optical focusing principle to carry out optical focusing in the shooting process. Specifically, the light passing through the light-transmitting mirror is reflected by the reflector into the focusing mirror assembly, and then is incident to the sensor through the focusing mirror assembly. And during shooting, the focusing motor can drive the focusing mirror assembly to move on the optical axis of the focusing mirror assembly so as to realize optical focusing.

At present, a reflector in a periscopic camera module is mainly a right-angle prism, and the right-angle prism is fixed through a fixing base. Referring to fig. 1, the right-angle prism includes three side surfaces, which may be divided into an incident surface, a reflection surface, and an exit surface according to their functions. Wherein, the reflecting surface is plated with an optical reflecting film and is used for reflecting light. The other sides of the direct prism than the three sides are used for bonding with a fixing base to fix the right-angle prism. The process of the right-angle prism for reflecting light can be seen in fig. 1, specifically, light enters the right-angle prism in a direction perpendicular to the incident surface, is then reflected by the reflecting surface onto the exit surface, and then exits from the exit surface. Because the volume of right angle prism is great usually, and weight is heavier, so the space that right angle prism took is great to also break away from fixed base when periscopic camera module takes place to shake or fall easily. In view of the disadvantages of the right-angle prism, a flat mirror having a thickness of 0.5mm (millimeters) or less is provided in the related art. The two surfaces of the plane reflector are plated with optical reflecting films, one surface is used for reflecting light rays passing through the light transmitting mirror to the focusing mirror assembly, and the other surface is used as an adhesive surface and is used for being adhered to the fixed base.

However, when the periscopic camera module shakes or falls, if the shear stress of the optical reflective film plated on the bonding surface is greater than the adhesive force, the optical reflective film plated on the bonding surface will tear, which affects the stability of the plane mirror, and further affects the reflection of the plane mirror to light and the imaging quality of the periscopic camera module.

Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Fig. 2 is a schematic structural diagram of a periscopic camera module according to an embodiment of the present application, and referring to fig. 2, the periscopic camera module includes a plane mirror 01, a fixed base 02, a focusing mirror assembly 03, and a sensor 04. The plane mirror 01 includes a first surface 011 and a second surface 012, the first surface 011 is adhered to the fixed base 02, and the second surface 012 is plated with an optical reflection film. The focusing mirror assembly 03 is located on the light exit side of the plane mirror 01, and the sensor 04 is located on the light exit side of the focusing mirror assembly 03. The thickness of the plane mirror 01 is greater than or equal to a thickness threshold.

The shape of the plane mirror 01 may be a rectangular parallelepiped, and the plane mirror 01 may be a front mirror. The optical reflection film is a reflection film that is plated on the second surface 012 and is used to reflect light incident on the second surface 012 into the focusing mirror assembly 03. For example, when an incident light ray is incident on the optical reflection film at an angle of 45 degrees, the incident light ray may be reflected by the optical reflection film into the focusing mirror assembly 03 at an angle of 90 degrees. The material of the optical reflection film can be preset according to the use requirement, and the embodiment of the application does not limit the material. The fixing base 02 is a member for fixing the plane mirror 01, and the shape, size, and the like of the fixing base 02 may be set according to the shape, size, and the like of the plane mirror 01 so that the first surface 011 of the plane mirror 01 can be bonded to the fixing base 02. The first surface 011 and the fixed base 02 may be bonded by glue or the like, which is not limited in the embodiments of the present application. The focusing mirror assembly 03 is an assembly for focusing incident light, and the focusing mirror assembly 03 may include a plurality of focusing mirrors. The sensor 04 is a device for converting an optical signal incident on its photosensitive surface into an electrical signal in a proportional relationship with the optical signal, and converting the electrical signal into an image signal to acquire an image.

In addition, the thickness threshold value is a thickness at which the flat mirror 01 is not deformed after the second surface 012 is coated with the optical reflection film. The thickness threshold may be in the range of 0.8-5 mm. Alternatively, the thickness threshold may be 0.8 millimeters.

Since the shape of the plane mirror may be a rectangular parallelepiped in one possible case, the positional relationship of the first surface 011 and the second surface 012 may be adjacent or opposite. Based on this, two possible implementations will be described in accordance with the positional relationship between the first surface 011 and the second surface 012.

In a first possible implementation, referring to fig. 3, the first surface 011 is adjacent to the second surface 012. That is, the plane of the first surface 011 intersects the plane of the second surface 012, and the first surface 011 and the second surface 012 share an edge.

In order to stabilize the position of the flat mirror 01 on the fixed base 02, referring to fig. 4, the flat mirror 01 includes a third surface 013, a fourth surface 014, and a fifth surface 015 in addition to the first surface 011 and the second surface 012, the third surface 013, the fourth surface 014, and the fifth surface 015 are adjacent to the second surface 012, and the third surface 013, the fourth surface 014, and the fifth surface 015 are adhered to the fixed base 02.

Since the third surface 013, the fourth surface 014, and the fifth surface 015 of the plane mirror 01 are bonded to the fixed base 02 except for the first surface 011 of the plane mirror 01, the bonding area between the plane mirror 01 and the fixed base 02 is increased. In this way, the adhesion between the plane mirror 01 and the fixing base 02 can be further secured, and the position of the plane mirror 01 on the fixing base 02 can be further secured.

In order to make the shape of the flat mirror 01 more stable and less prone to deformation, referring to fig. 5, the flat mirror 01 includes a sixth surface 016 in addition to a first surface 011, a second surface 012, a third surface 013, a fourth surface 014, and a fifth surface 015, the sixth surface 016 is opposite to the second surface 012, and the sixth surface 016 is coated with an optical reflective film.

The optical reflective film plated on the sixth surface 016 may be the same as or different from the optical reflective film plated on the second surface 012 in material and thickness, and the embodiment of the present invention is not limited thereto. The area of the sixth surface 016 may be the same as that of the second surface 012, or the area of the sixth surface 016 may be different from that of the second surface 012, which is not limited in this embodiment.

In a possible implementation manner, the sixth surface 016 may be adhered to the fixing base 02 to further increase the adhesion area of the plane mirror 01 to the fixing base 02, so that the adhesion of the plane mirror 01 to the fixing base 02 is firmer, and the position of the plane mirror 01 on the fixing base 02 is firmer.

It should be noted that, in a possible case, the optical reflective film plated on the second surface 012 has a certain stress, and under the stress of the optical reflective film itself, the plane mirror 01 may be bent, so as to affect the reflection of the light by the plane mirror 01, and further affect the imaging quality of the acquired image. Therefore, by plating the optical reflective film on the sixth surface 016 of the plane mirror 01 opposite to the second surface 012, the self-stress of the optical surface film plated on the second surface 012 can be reduced, thereby avoiding the above situation.

In a second possible implementation, referring to fig. 6, the first surface 011 is opposite to the second surface 012. That is, the first surface 011 and the second surface 012 have no common edge.

In order to stabilize the position of the flat mirror 01 on the fixing base 02, referring to fig. 7, the flat mirror includes a third surface 013, a fourth surface 014, a fifth surface 015, and a sixth surface 016 in addition to the first surface 011 and the second surface 012, the third surface 013, the fourth surface 014, the fifth surface 015, and the sixth surface 016 are adjacent to the second surface 012, and the third surface 013, the fourth surface 014, the fifth surface 015, and the sixth surface 016 are adhered to the fixing base 02.

Since the third surface 013, the fourth surface 014, the fifth surface 015, and the sixth surface 016 of the plane mirror 01 are bonded to the fixed base 02 except for the first surface 011 of the plane mirror 01, the bonding area between the plane mirror 01 and the fixed base 02 is increased. In this way, the adhesion between the plane mirror 01 and the fixing base 02 can be further secured, and the position of the plane mirror 01 on the fixing base 02 can be further secured.

Specifically, when the periscopic camera module is used to acquire an image, the periscopic camera module may be placed in a shooting scene with light, the plane mirror 01 may be directed at a person or an object to be shot, the light on the surface of the person or the object may be reflected onto the plane mirror 01, and then may be incident into the focusing mirror assembly 03 through reflection of the plane mirror 01, and then may be incident onto the sensor 04 through focusing of the focusing mirror assembly 03, and finally, the image may be acquired through the sensor 04.

Optionally, referring to fig. 8, the periscopic camera module further includes a transparent mirror 05, the second surface 012 is located on the light exit side of the transparent mirror 05, and an included angle between the second surface 012 and a plane where the transparent mirror 05 is located is a reference angle. The reference angle is an angle at which the plane mirror 01 reflects the light incident on the second surface 012 to the focusing mirror assembly 03.

The light-transmitting mirror 05 is a single lens made of transparent glass or plastic. The number of the transparent mirrors 05 may be plural, and the plural transparent mirrors 05 may constitute a transparent mirror combination, that is, the second surface 012 may be located on the light emitting side of the transparent mirror combination constituted by the plural transparent mirrors 05. In practical application, the number, type, size and the like of the transparent mirror 05 can be set according to use requirements, and the embodiment of the application does not limit the number, the type, the size and the like. In a possible implementation manner, the light-transmitting mirror 05 can collect light incident on the plane mirror 01, so that the shooting visual field of the periscopic camera module is wider. In addition, the reference angle may be preset according to a use requirement, and the embodiment of the present application does not limit this. For example, the reference angle may be in the range of 30-60 degrees. Alternatively, the reference angle may be 45 degrees.

Optionally, in order to more conveniently realize focusing of the focusing mirror assembly 03, the periscopic camera module may further include a focusing motor 06, and the focusing motor 06 is configured to drive the focusing mirror assembly 03 to move on the optical axis of the focusing mirror assembly 03 to realize focusing during operation. The type, specification, and installation position of the focus motor 06 may be preset according to the use requirement, which is not limited in the embodiment of the present application.

In the embodiment of the present application, the periscopic camera module includes a plane mirror 01, a fixed base 02, a focusing mirror assembly 03, and a sensor 04. The plane mirror 01 includes a first surface 011 and a second surface 012, the first surface 011 is adhered to the fixed base 02, and the second surface 012 is plated with an optical reflection film. Since the thickness of the plane mirror 01 is greater than or equal to the thickness threshold, the plane mirror 01 will not deform under the self-stress of the optical reflective film plated on the second surface 012 due to its small thickness, so as to affect the reflection of the plane mirror 01 to the light. In addition, the first surface 011 of the plane mirror 01 is adhered to the fixed base 02, and the first surface 011 is not coated with the optical reflection film, that is, the adhering surface adhered to the fixed base 02 is not coated with the optical reflection film. Therefore, the optical reflection film plated on the bonding surface can not be torn when the periscopic camera module shakes or falls, and the stability of the plane mirror 01 is affected. That is, the plane mirror 01 that the periscopic camera module that this application embodiment provided included is difficult to deform, and the steadiness is higher for the image quality of the image that this periscopic camera module acquireed is higher.
