BACKGROUND
1. Technical Field
The present disclosure relates to mounting devices, and particularly to a mounting device for a camera module.
2. Description of Related Art
Camera modules are in electronic devices such as mobile phones and computers. Generally, the camera module is adhered to a front cover of the electronic device and then secured to the front cover with screws, which is inconvenient and time consuming. Therefore, there is room for improvement in the art.
BRIEF DESCRIPTION OF THE DRAWINGS
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
FIG. 1 is an exploded, isometric view of one embodiment of a mounting device and a camera module.
FIG. 2 is an enlarged view of a circled portion II of the mounting device and the camera module of FIG. 1.
FIG. 3 is an assembled, isometric view of the mounting device and the camera module of FIG. 1.
FIG. 4 is a top view of the mounting device and the camera module of FIG. 3.
DETAILED DESCRIPTION
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
FIG. 1 shows one embodiment of a mounting device for securing a camera module 100. The camera module 100 includes a circuit board 10 and a camera 20. The circuit board 10 includes a first end 11 and a second end 12 opposite to the first end 11. The second end 12 includes a blocking edge 121. In one embodiment, the blocking edge 121 is substantially perpendicular to a top surface of the circuit board 10.
The mounting device includes a resilient member 30 and a front plate 50. The resilient member 30 includes a resisting piece 31, two resilient pieces 33, and two positioning pieces 35. The two resilient pieces 33 extend from opposite ends of the resisting piece 31. A first angle is defined between the resisting piece 31 and each resilient piece 33. The first angle is obtuse. Each positioning piece 35 extends from one of the two positioning pieces 35, and the two positioning pieces 35 extend in opposite directions. In one embodiment, the resisting piece 31 is substantially parallel to each positioning piece 35. When the resilient member 30 is located in an uncompressed initial position, a first distance is defined between the resisting piece 31 and each positioning piece 35.
Referring to FIGS. 1 and 2, a limiting portion 51 and a latching portion 53 extend from the front plate 50. The limiting portion 51 defines a positioning slot 511. An extending direction of the positioning slot 511 is substantially parallel to the front plate 50. The latching portion 53 includes a first latching piece 531 and two second latching pieces 532 extending from the first latching piece 531. In one embodiment, the first latching piece 531 is substantially perpendicular to the font covering plate 50, and each second latching piece 532 is substantially “L” shaped. A latching slot 535 is defined between the first latching piece 531 and each second latching piece 532. A protrusion 536 extends from each second latching piece 532 into the latching slot 535. The latching slot 535 is used for engaging the positioning piece 35. A plurality of the first limiting pieces 55 and a plurality of second limiting pieces 56 extend from opposite ends of the front plate 50.
Referring also to FIGS. 3 and 4, in assembly, the resilient member 30 is placed on the front plate 50 with the two positioning pieces 35 inserted in the two latching slots 535. The camera module 100 is moved to the front plate 50 and located between the first limiting pieces 55 and the second limiting pieces 56. The first end 11 of the circuit board 10 is poised above the positioning slot 511. The second end 12 is pressed against the resilient member 30, to elastically deform the resilient piece 33, until the first end 11 of the circuit board 10 can be lowered to the front plate 50 and allowed to enter the positioning slot 511 by the pushing force of the resilient member 30 restoring itself. The two resilient pieces 33 are elastically deformed away from each other, and the two positioning pieces 35 are inserted into the two latching slots 535 further. The second end 12 is moved over the resilient member 30, and the blocking edge 121 abuts the resisting piece 31. The resisting piece 31 exerts elastic force to engage the circuit board 10 to the front plate 50. The protrusion 536 abuts the positioning piece 35, preventing the positioning piece 35 from disengaging from the latching slot 535. In this position, the resilient member 30 is located in a securing position, a second angle is defined between each resilient piece 33 and the resisting piece 31, and a second distance is defined between the resisting piece 31 and the positioning piece 35. The second angle is larger than the first angle. The first distance is greater than the second distance.
In disassembly, the two resilient pieces 33 are deformed towards each other to disengage the positioning piece 35 from the latching slot 535, allowing the second end 12 to be lifted from the front plate 50. Thus, the camera module 100 can be removed from the front plate 50 after the first end 11 is pulled out of the positioning slot 511.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure, to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
