In the cover 10 shown in fig. 5, the cover 10 has a rectangular parallelepiped structure, that is, a rectangular space. In this case, the number of the side walls 12 is four, and the four side walls 12 are connected in sequence and are connected to the top plate 11, respectively, so as to enclose a space for accommodating the two imaging units 20A and 20B. In the present embodiment, in order to increase the structural strength of the cover 10, a rib 13 is provided in the space, the rib 13 is connected to the top plate 11 and the side wall 12, and the rib 13 is used to separate adjacent image pickup units, and in the present embodiment, the rib 13 divides the space into two parts, each part being used to accommodate one image pickup unit. It should be understood that the number of the ribs 13 in the cover 10 is not limited to one, as shown in fig. 6, and in other embodiments, when the distance between two adjacent camera units is large, two ribs 13 may be used, so as to ensure the structural strength of the cover 10. In the specific manufacturing of the cover 10, the structural strength of the cover 10 is improved.

This cover body 10 is when specifically making, in order to improve the structural strength of the cover body 10, this cover body 10 adopts the integrated into one piece structure, and roof 11 and lateral wall 12 adopt a monoblock metal sheet punching press to form promptly, perhaps adopt the integrative injection moulding of plastic material, when adopting the metal punching press, if adopt steel sheet, aluminum plate to pass through the cover body 10 of punching press formation integrated into one piece structure. The overall structural strength of the cover 10 is improved by stamping a single sheet of metal, and the efficiency of the cover 10 in manufacturing is improved by the above method. In addition, when the above-mentioned manner is adopted, since the top plate 11 and the side wall 12 are not required to be connected in other connection manners, the volume of the cover body 10 can be reduced to the maximum extent on the premise of ensuring the supporting strength of the cover body 10, so that the miniaturization development of the whole camera module is facilitated, and the internal space area of the electronic device occupied by the camera module is further reduced.

As can be seen from the above description, the cover 10 provided in this embodiment is used to protect the camera units 20A and 20B, and when assembled, the camera units 20A and 20B are placed in the space and adhesively connected to the top plate 11 through the fixing adhesive layer, and after assembled, the following requirements are met: the distance between the centers of the lenses 21A, 21B in the adjacent two image pickup units 20A, 20B is larger than the set distance d. Thereby the effect of camera module when making a video recording is guaranteed. And when the distance between the centers of the lenses 21A and 21B of the two camera units 20A and 20B is greater than the requirement of the set distance D, the camera module can be applied to a 3D camera scene, so that the 3D camera scene is ensured to have a sufficient viewing angle, and the camera effect is improved. In a particular embodiment, the set distance d is 10 mm.

When the camera units 20A and 20B are assembled with the cover 10, the fixed connection between the two is realized by the fixing adhesive layer, and the connection strength between the two is ensured by the fixing adhesive layer. In a specific arrangement, the fixing adhesive layer includes, but is not limited to, a heat-curable adhesive, and includes, but is not limited to, a light-curable adhesive.

Specifically, the fixing adhesive layer includes a thermosetting adhesive layer 50 and a light-curing adhesive layer 60, wherein the light-curing adhesive layer 60 is disposed at a position corresponding to the light irradiation hole on one surface of the camera unit 20A, 20B facing the housing; a thermosetting adhesive layer 50 provided on one surface of the imaging units 20A and 20B facing the cover; in a specific arrangement, the thermosetting adhesive layer 50 is disposed on the upper surface of the portion of the top plate 11 covering the image pickup units 20A and 20B, so that the thermosetting adhesive layer 50 can be fixed by adhesion between the image pickup units 20A and 20B and the top plate 11.

Since the camera module of the present embodiment fixes the camera units 20A and 20B by the cover 10, the optical adhesive layer 60 and the thermosetting adhesive layer 50, the optical adhesive layer 60 can provide a false fixing function for the camera units 20A and 20B in the cover 10, and the relative position between the camera units 20A and 20B and the cover 10 is maintained by the optical adhesive layer 60, so that the thermosetting adhesive layer 50 can be cured and the camera units 20A and 20B can be well fixed in the cover 10.

The material of the thermosetting adhesive layer 60 includes, for example, a thermosetting resin, and the material of the thermosetting adhesive layer 50 includes a thermosetting resin. Accordingly, the thermosetting adhesive layer 60 may provide a function of pseudo-fixation before the thermosetting adhesive layer 50 is cured via irradiation of a light beam having a specific wavelength, but the present novel concept is not limited thereto.

Meanwhile, since the thermosetting adhesive layer 60 and the thermosetting adhesive layer 50 provide a stable adhesive effect between the top plate 11 of the enclosure 10 and the upper surfaces of the camera units 20A and 20B, a space for filling adhesive between the side wall 12 of the enclosure 10 and the camera units 20A and 20B may not be provided, thereby reducing the overall volume of the camera module. Further, the gap between the side wall 12 of the cover 10 and the side surface of the imaging unit 20A, 20B is not sufficient to fill the thermosetting adhesive layer 60 or the thermosetting adhesive layer 50.

When the camera is used specifically, thermosetting adhesive is coated on one side of the top plate 11 facing the space, then the camera units 20A and 20B are placed in the cavity, light curing adhesive is coated on the camera units 20A and 20B, ultraviolet rays can be irradiated to the light curing adhesive through the arranged irradiation holes 111, and therefore the light curing adhesive is hardened to adhere the camera units 20A and 20B and the top plate 11 together. The light-cured adhesive layer can provide false fixing function for the camera units 20A and 20B in the cover body 10, so that the cover body 10 and the camera units 20A and 20B are fixed through the light-cured adhesive layer on a production line, and then the camera module is placed into the heating box and cured through thermosetting adhesive, so that the production efficiency of the camera module is improved.

In order to ensure that the bonding between the cover 10 and the camera units 20A and 20B is stable when the illuminating holes 111 are specifically arranged, it is preferable that four illuminating holes 111 surrounding the lens 21 of each camera unit 20A and 20B are arranged on the top plate 11. As shown in fig. 2, the camera units 20A and 20B are correspondingly connected to the top plate through four light-curing adhesive layers 60, when the light holes 111 are specifically arranged, the four light holes 111 are arranged around the through holes, that is, the light holes 111 are arranged around the lenses 21A and 21B of the camera units 20A and 20B, when the camera units are specifically adhered, the light-curing adhesive layers 60 can fix the camera units 20A and 20B around the lenses 21A and 21B, so that the camera units 20A and 20B can achieve the dual effects of positioning and adhering, and the stability of the whole camera module during assembly is improved.

As can be seen from the above description, the camera module provided in this embodiment adopts the cover 10 to fix the camera units 20A and 20B, so as to improve the stability of the camera units 20A and 20B, and when the camera module is fixed, the distance between the centers of the lenses 21A and 21B of the camera units 20A and 20B is greater than the set distance, so that the camera units 20A and 20B can adapt to the dual-camera display on the electronic device.
