The bracket cover 102 and the bracket base 101 constitute an accommodating chamber for accommodating the camera module 20 . The group 20 is fixed in the bracket cover 102, and may be fixed in the bracket cover 102 by an adhesive layer such as a back glue. The bracket base 101 is a long base, the bracket cover 102 is a square cover, and one side of the square cover is parallel to the long side of the long base, and the length of the bracket base 101 is longer than the two bracket covers 102 In order to reserve a certain gap in the middle of the bracket base 101 after the two bracket covers 102 are embedded in the bracket base 101 , the gap can be used for setting the structural components of the driving mechanism 30 .

In this embodiment, the bracket base 101 includes two sets of first positioning holes 103 corresponding to the two bracket covers 102 respectively, and each bracket cover 102 includes a set of second positioning holes 104 . The hole 103 and the second positioning hole 104 may be connected by a fixing member 105 such as a screw. Wherein, each group of first positioning holes 103 is distributed in two opposite frames of the bracket base 101 and penetrates the frame, and each group of second positioning holes 104 is distributed in the corresponding two frame surfaces of the bracket cover 102, and the fixing member 105 passes through The first positioning hole 103 and the second positioning hole 104 fix the bracket cover 102 in the bracket base 101 in a double-center positioning method. This fixing method has high positioning reliability. At this time, it is used to fix the same bracket cover 102 The connection line between the two first positioning holes 103 can constitute a predetermined axis, so the bracket cover 102 can drive the camera module 20 to rotate around the predetermined axis.

Based on the above structure, referring to FIG. 3 , the driving mechanism 30 may include a driving motor 301 and a sliding block 302 . The end of the sliding block 302 is connected to the driving motor 301 , for example, an opening is provided at the end of the sliding block 302 , and the driving motor 301 Using a stepper motor, the slider can move linearly under the drive of the stepper motor.

Referring to FIG. 4 , the bracket cover 102 may include a first slideway 1020 , and the first slideway 1020 is located on the opposite side of the two bracket covers 102 , which can be specifically arranged at the bottom of the bracket cover 102 , and of course can also be arranged at the bottom of the bracket cover 102 . The side wall of the bracket cover 102 only needs to be on the side facing the opening; with reference to FIG. 5 , the slider 302 may include second slideways 3020 , the second slideways 3020 are located on opposite sides of the slider 302 and It can be in sliding contact with the first slideway 1020; wherein, one of the first slideway 1020 and the second slideway 3020 is a fixed-section slideway, and the other is a variable-section slideway. At this time, the first slideway 1020 can be When sliding relative to the second slideway 3020 , the bracket cover 102 is driven to rotate around a preset axis.

For example, taking the first slideway 1020 on the side of the bracket cover 102 as a fixed-section slideway, and the second slideway 3020 on the side of the slider 302 as a variable-section slideway, FIG. 6 exemplarily shows the camera assembly. Schematic diagram of the driving process. The driving motor 301 extends into the opening at the end of the slider 302 and drives the slider 302 to move linearly. At this time, the second slideway 3020 of the slider 302 is in contact with the first slideway 1020 of the bracket cover 102 . Relative sliding occurs. Since the first slide 1020 is a fixed-section slide and the second slide 3020 is a variable-section slide, the two will cause the bracket cover to become larger due to the increase in the cross-sectional area of the contact surface during the relative sliding process. 102 is gradually raised, thereby driving the left camera module 20 to rotate counterclockwise around the preset axis, and the right camera module 20 to rotate clockwise around the preset axis, so that the backs of the two camera modules 20 are inclined relative to each other In this state, a larger shooting angle can be obtained.

Further, as shown in FIG. 3 , two sets of elastic components 107 such as springs or shrapnel are provided at the bottom of the bracket base 101 respectively corresponding to the two accommodating chambers. The elastic components 107 are located on the bottom surface of the bracket base 101 and close to The preset axis is deviated from the position of the outer edge of the bracket base 101 , for example, the left elastic component 107 is located at the position where the left preset axis is deviated from the left edge of the bracket base 101 , and the right elastic component 107 is located on the right preset axis The position biased towards the right edge of the bracket base 101 , where the left side and the right side are opposite, can be determined with reference to FIG. 3 , and vice versa.

Based on this, the bottom edge of the bracket cover 102 provided with the first slideway 1020 and the elastic component 107 located on the bottom surface of the bracket base 101 can support the bottom surface of the camera module 20 and ensure that the camera component 20 only faces the preset The direction is rotated, that is, the first slideway 1020 points to the direction of the elastic component 107 . When the camera module 20 is rotated to the inclined state, the elastic member 107 is in a compressed state, and when the camera module 20 needs to be reset, it is only necessary to reversely rotate the driving motor 301 to make the slider 302 move outwards. At this time, the elastic member 107 can realize the automatic reset function of the camera by using its own elastic potential energy.

In this way, the camera assembly provided by the embodiment of the present disclosure can rotate the two camera modules 20 in opposite directions as required, so that when the two camera modules 20 are in a tilted state, a wide-angle picture can be captured, and The two camera modules 20 can also be restored to a parallel state through the automatic reset function of the elastic component 107 when the wide-angle shooting is not required.
