Referring to fig. 1 and 2, an electronic device such as a mobile phone 100 generally includes a display screen 10, a middle frame 20, a circuit board 40 and a camera module, the display screen 10 is disposed on one side of the middle frame 20, wherein the display screen 10 may be disposed on one side of the middle frame 20 by bonding or the like, so as to fix the display screen 10 on the middle frame 20, and a surface where the display screen 10 is located forms a front surface of the electronic device. The side of the middle frame 20 facing away from the display screen 10 has an inner cavity 21, and the circuit board 40 is disposed in the inner cavity 21 so as to facilitate the assembly of the circuit board 40 in an electronic device such as a mobile phone 100. The circuit board 40 can be understood as a main board in the mobile phone 100. The motherboard generally carries electronic devices such as a processor module, various controller modules, a storage module, a communication module, a radio frequency module, a power management module and the like.

As shown in fig. 2, a camera assembly may be disposed on the circuit board 40, the camera assembly including a camera module 50, the camera module 50 in the camera assembly being electrically connected to the circuit board 40. Since the camera assembly is disposed on the circuit board 40, the camera assembly may also be disposed in the interior cavity 21. At this time, the camera module 50 in the camera module can be regarded as a built-in camera module of an electronic apparatus such as the cellular phone 100.

Referring to fig. 1 and 2, the electronic device further includes a battery cover 30, and the battery cover 30 is disposed on a side of the middle frame 20 facing away from the display screen 10. The battery cover 30 may include a battery cover body 31 and a lens 32, the battery cover body 31 may be disposed on one side of the middle frame 20 by adhesion or the like, so as to fix the battery cover 30 on the middle frame 20, and a surface on which the battery cover 30 is disposed forms a back surface of the electronic device. The portion of the bezel 20 exposed at the surface of the electronic device forms a sidewall of the electronic device, such as the cell phone 100. The lens 32 is disposed on the battery cover body 31 and opposite to the camera module 50. The lens 32 is provided with a light hole 321, so that the electronic device, such as external ambient light, can enter the center of the lens through the light hole 321, thereby implementing the shooting function of the camera module 50.

Fig. 1 and 2 only illustrate one camera module 50. The number of the image capturing modules 50 in the electronic device, such as the mobile phone 100, is not limited to one, and the number of the image capturing modules 50 may also be two or more than two. When the number of the camera modules 50 is plural, the plural camera modules 50 may be arranged at will on the back of the electronic device, and specifically, the related settings in the electronic device in the prior art may be referred to, and in this application, no further limitation is made.

Fig. 3 illustrates a partial schematic view of a battery cover in an electronic device.

Referring to fig. 1 to 3, the battery cover 30 has a light inlet 311, and the light inlet 311 is disposed opposite to the camera module 50. The light inlet 311 can be disposed opposite to the lens center of the camera module 50 and the light inlet 321 on the lens 32, that is, the light inlet 311 is aligned with the lens center and the light inlet 321, so that the ambient light can enter the lens center through the light inlet 321 and the light inlet 311, thereby implementing the shooting function of the camera module 50.

It should be noted that the camera module 50 of the present embodiment can be understood as a rear camera module on an electronic device such as the mobile phone 100. The camera module 50 may include, but is not limited to, a variable Focus module such as an Auto Focus (AF) module, a Fixed Focus (FF) module, a wide angle camera module, a telephoto camera module, a color camera module, or a black and white camera module.

As shown in fig. 3, the battery cover 30 has a plurality of positioning members 312 on the circumferential side of the light inlet hole 311. For example, the positioning element 312 may include, but is not limited to, a positioning post, which may also be referred to as an insertion drum on the battery cover 30. The plurality of positioning members 312 are located on one side of the battery cover 30 facing the circuit board 40, and the plurality of positioning members 312 can be assembled on the camera module 50, so that the camera module 50 can be positioned by matching and connecting the positioning members 312 with the camera module 50, and the lens center of the camera module 50 is aligned with the light inlet 311 and the light transmitting 321. In addition, when the lens center of the camera module 50 deviates from the position of the light hole 321, the assembling position of the camera module 50 on the circuit board 40 can be adjusted under the pushing of the positioning members 312, so that the lens center of the camera module 50 is aligned with the light inlet 311 and the light hole 321 (i.e., the camera module 50 is eccentrically aligned by the positioning members 312), thereby realizing the accurate positioning of the camera module 50.

To avoid a large positional deviation of the camera module 50 on the circuit board 40, the assembling position of the camera on the circuit board 40 needs to be pre-positioned in multiple directions before the positioning member 312 is assembled to the camera module 50. For example, the camera needs to be positioned in the length direction, width direction and thickness direction of the electronic device to ensure the positioning member 312 is smoothly assembled on the camera module 50. The positioning member 312 can be understood as a fine positioning structure of the camera module 50 on the battery cover 30. Here, the length direction of the electronic device may be understood as the Y direction in fig. 1 and 2, the width direction of the electronic device may be understood as the X direction in fig. 1 and 2, and the thickness direction of the electronic device may be understood as the Z direction in fig. 2.

Wherein, be provided with the clearance between the inner wall of the lateral wall of the module of making a video recording 50 and mounting hole to when guaranteeing to carry out eccentric counterpoint to the module of making a video recording 50 through setting element 312, can restrict the module of making a video recording 50 and take place great skew for X direction and Y direction on circuit board 40, thereby realize the prepositioning to the module of making a video recording 50.

However, in the process of mounting the motherboard bracket on the camera module 50, since the camera module 50 has no positioning structure on the circuit board 40, the camera module 50 may have a large position offset relative to the circuit board 40 and the motherboard bracket, and interfere with the motherboard bracket, which may affect the detachment of the motherboard bracket.

Therefore, in order to avoid the position offset of the camera module 50 on the circuit board 40, in the related art, an opening is formed on the circuit board 40, so that when the camera module 50 is disposed in the opening, the camera module 50 is limited by the hole wall of the opening, and the pre-positioning of the camera module 50 on the circuit board 40 is realized, so that the mainboard support and the positioning element 312 on the battery cover 30 can be smoothly assembled on the camera module 50.

Currently, with the continuous development of technologies, electronic devices such as the mobile phone 100 are continuously developing in research and development directions of pursuing lightness, thinness and long endurance. To meet the needs of light weight, thinness, and long endurance of electronic devices, the area of the circuit board 40 in the electronic device such as the mobile phone 100 is smaller and smaller. Because a plurality of electronic components are arranged on the substrate of the circuit board 40, in order to ensure the area of the cloth piece on the circuit board 40, the circuit board 40 may not be holed at the assembly position of the camera module 50 (for example, the camera module 50 is a stacked design structure), and therefore, before the main board bracket is installed, how to implement the prepositioning of the camera in multiple directions becomes a technical problem to be solved.

In view of this, the embodiment of the present application provides a camera module, which can be applied to an electronic device, wherein the camera module is provided with a first support 60 and a second support 70, and the camera module 50 can be pre-positioned in multiple directions through the cooperation between the second support 70 and the first support 60, so that the camera module 50 does not need to be pre-positioned by a motherboard support while the positioning member 312 is successfully assembled on the camera module 50.

Fig. 6 illustrates a cross-sectional view of fig. 5 in the direction a-a.

To facilitate the assembly of the first bracket 60, referring to fig. 6 in combination with fig. 4, the second bracket 70 includes a surrounding barrier 71, the surrounding barrier 71 surrounds the circuit board 40 to form a closed shape, and forms an assembly chamber 80 adapted to the first bracket 60 together with the circuit board 40. The side of the assembly chamber 80 facing the first bracket 60 is an open end 81. The enclosure 71 may be fixed on the circuit board 40 by soldering or the like. Through enclosing the setting of the equipment room 80 that fender 71 and circuit board 40 formed like this, not only can be convenient for the equipment of first support 60 and camera module 50 on circuit board 40, can be convenient for carry on spacingly through second support 70 to the position of camera module 50 on circuit board 40 moreover.

Referring to fig. 6, the first bracket 60 has a fitting end 611, and the fitting end 611 is disposed in the assembly chamber 80 through the open end 81. The open shape of the open end 81 is adapted to the structure of the mounting end 611 to facilitate the mounting of the first bracket 60 and the camera module 50 in the second bracket 70. The inner wall of the assembly chamber 80 is spaced from the fitting end 611, and the inner wall of the assembly chamber 80 is used for limiting the position of the camera module 50 in the direction parallel to the circuit board 40. Wherein the X-direction and the Y-direction may constitute a first plane parallel to the direction of the circuit board 40. Through the setting of interval between the inner wall of equipment room 80 and the assembly end 611 like this, not only can be convenient for first support 60 and the equipment of the module 50 of making a video recording on circuit board 40, realize the quick assembly disassembly of the module 50 of making a video recording, can be convenient for moreover under the promotion of setting element 312, the module 50 of making a video recording and first support 60 can take place less offset in the first plane for second support 70 in equipment room 80, realize the eccentric counterpoint to the module 50 of making a video recording.

Meanwhile, when the camera module 50 and the first bracket 60 are pushed by an external force and have an excessive position deviation in the first plane relative to the first bracket 60 in the assembly chamber 80, the first bracket 60 interferes with the inner wall of the assembly chamber 80, so that the camera module 50 is pre-positioned in the first plane by the inner wall of the assembly chamber 80, the camera module 50 is prevented from moving in a large position relative to the circuit board 40 in the first plane, and the positioning piece 312 on the battery cover 30 of the electronic device is favorably assembled on the camera module 50.

In order to facilitate the electrical connection between the camera module 50 and the circuit board 40, referring to fig. 6 and referring to fig. 4, a flexible circuit board 523 electrically connected to the circuit board 40 is disposed on a side of the camera module 50, wherein the flexible circuit board 523 may be disposed on a side of the image sensor 522 and electrically connected to the image sensor 522. The end of the flexible circuit board 523 may be electrically connected to the circuit board 40 by an electrical connector. For example, the male socket 90 of the electrical connector may be disposed at an end of the flexible circuit board 523, the circuit board 40 may be disposed with a female socket (not labeled in the figure) of the electrical connector, and when the camera module 50 is preset on the circuit board 40 through the first bracket 60 and the second bracket 70, the end of the flexible circuit board 523 may be plugged into the female socket through the male socket 90, so as to electrically connect the camera module 50 to the circuit board 40.

In the process of assembling the camera module 50 to the second bracket 70, the flexible circuit board 523 may deform toward the side away from the circuit board 40 and generate a certain elastic force F. Under the action of the elastic force F, the camera module 50 and the first bracket 60 rotate in the second bracket 70 around the side of the camera module 50 departing from the flexible circuit board 523 relative to the second bracket 70, so that the pre-positioning effect of the camera module 50 on the circuit board 40 is influenced, and the smooth assembly of the positioning member 312 on the battery cover 30 on the camera module 50 is influenced.

The second bracket 70 elastically abuts against the elastic arm 6111. Thus, when the first bracket 60 is assembled in the first bracket 60 through the assembling end 611, the second bracket 70 abuts against the elastic arms 6111 elastically, the elastic arms 6111 elastically deform to a certain degree, and under the action of the elastic deformation of the elastic arms 6111, the elastic force generated when the flexible circuit board 523 deforms can be offset, so that the camera module 50 and the first bracket 60 are prevented from moving relative to the second bracket 70, such as rotating, under the driving of the elastic force F of the flexible circuit board 523, the pre-positioning of the camera module 50 on the first plane is realized jointly through the interference of the inner wall of the assembling chamber 80 and the first bracket 60, and the smooth assembly of the positioning piece 312 on the battery cover 30 on the camera module 50 is ensured.

Meanwhile, since the second bracket 70 is elastically abutted against the elastic arm 6111, the camera module 50 and the first bracket 60 can still be pushed by the positioning element 312 in the assembly chamber 80, and a small positional deviation occurs in the first plane relative to the second bracket 70, so that the assembly position of the camera module 50 on the circuit board 40 is adjusted, and thus the eccentric alignment of the positioning element 312 to the camera module 50 is realized.

The spring arm 6111 may be partially located within the assembly chamber 80 as shown in FIG. 6, or the spring arm 6111 may be located entirely within the assembly chamber 80. In the present application, it is not further limited whether the elastic arms 6111 are all located in the assembly chamber 80, and it is only necessary to ensure that the elastic arms 6111 can elastically abut against the second bracket 70 in the assembly chamber 80.

The first limiting portion 72 is connected to the surrounding barrier 71 and disposed opposite to the elastic arm 6111, and the first limiting portion 72 is elastically abutted to the elastic arm 6111 to counteract the elastic force F generated when the flexible circuit board 523 deforms. Like this when first support 60 passes through the assembly end 611 and assembles in first support 60, first spacing portion 72 will also take place elastic deformation with elastic arm 6111 together, when being convenient for second support 70 and elastic arm 6111 elasticity butt, can also strengthen the elasticity butt effect of second support 70 and elastic arm 6111, thereby better offset the elasticity F of flexible circuit board 523, can be better avoid making a video recording module 50 and first support 60 to remove for second support 70 under elasticity F's drive in the time, can also be convenient for setting element 312 to promote to make a video recording module 50 and first support 60 and remove in assembly chamber 80, realize the eccentric counterpoint of setting element 312 to making a video recording module 50.

At this time, the end of the elastic bending part may constitute a cantilever structure on the second bracket 70. The end of the elastic bending portion and the distance between the surrounding baffle 71 can form a deformation space of the elastic bending portion, so that when the end of the elastic bending portion abuts against the elastic arm 6111, the end of the elastic bending portion can be elastically deformed towards one side of the surrounding baffle 71, and the abutting effect of the first limiting portion 72 and the elastic arm 6111 is ensured. In addition, after the camera module 50 is disposed in the first bracket 60, the assembly end 611 is assembled in the assembly chamber 80 along the direction of the open end 81 of the assembly chamber 80, and the end of the elastic bending portion is bent toward the assembly chamber 80, so that the elastic arm 6111 can act on the end of the elastic bending portion during the assembly of the first bracket 60, and the assembly of the first bracket 60 and the camera module 50 in the second bracket 70 can be facilitated while the elastic arm 6111 is elastically abutted against the elastic bending portion.

Wherein the ends of the resilient fold may be parallel to the surround 71 as shown in figure 7. Alternatively, the end of the elastic bending part may be inclined with respect to the surrounding barrier 71. In this embodiment, the end of the elastic bending portion is parallel to the surrounding barrier 71, so that the abutting area between the end of the elastic bending portion and the elastic arm 6111 is increased, the reliability of the elastic abutting between the end of the elastic bending portion and the elastic arm 6111 is enhanced, and the structure of the second bracket 70 can be simplified.
