Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic devices, and in particular to a camera module and an electronic device. BACKGROUND

[0002] With the rapid development of modern electronic technology, consumers' demand for the lightness and thinness of portable electronic devices such as mobile phones and laptops is increasing. This trend not only promotes the innovation of hardware design, but also drives the continuous evolution of components towards miniaturization and integration. Among them, the reduction in size of the lens, as an important visual input device, is particularly significant.

[0003] In the assembly process of the lens assembly, the lens holder or fixing seat (i.e. Holder) plays a crucial supporting and fixing role, which ensures that the lens can be stably mounted on the printed circuit board (PCB) to achieve accurate image capture function. The traditional Holder fixing method mainly adopts the glue bonding technology, that is, the Holder is directly pasted on the surface of the PCB through a specific adhesive. The advantage of this method is that it is simple to operate, low in cost, and can meet the basic fixing needs to a certain extent.

[0004] However, as the size of the lens continues to shrink, the bonding area between the Holder and the PCB also decreases, which poses a serious challenge to the traditional bonding method. Specifically, when the adhesive area of the Holder becomes very limited, the traditional straight edge structure bonding method cannot fully utilize the contact area between the Holder and the PCB, resulting in the fact that the glue can only adhere to the local surface of the Holder. In this case, the adhesive strength between the Holder and the PCB will be greatly reduced, and it is difficult to withstand the mechanical stress brought by long-term use and external environmental changes.

[0005] More seriously, in the drop verification link of electronic product reliability test, due to the insufficient adhesive strength, the Holder is prone to delamination. This not only directly leads to the loosening or falling off of the lens assembly, thereby affecting the camera function of the device, but also may cause more serious hardware failure due to internal circuit short circuit or open circuit, ultimately affecting the user experience and increasing the maintenance cost of the product.

[0041] First embodiment

[0042] In some example embodiments, as shown in FIG. 1, a camera module is applied to an electronic device such as a mobile phone, a tablet computer, a portable computer, etc. to meet the user's demand for camera. Figures 1-4

[0043] The camera module includes a lens 1, a circuit board 2, a support seat 3 (Holder) and a glue layer 4. Of course, it can be understood that the camera module also includes a protective film, a motor (VCM), an IR filter, a gold wire, a sensor, electronic components and the like. The lens 1 is used to collect and refract light onto the sensor. The motor moves the lens 1 to achieve optical zoom. The IR filter is used to filter infrared light to avoid red bias in the picture. The sensor is a light-sensitive element that converts light signals into electrical signals and finally generates image data. The above-mentioned electronic components cooperate to support the normal use of the camera module. The actual situation is specific, and here it is not specifically limited.

[0044] ​The support seat 3 is a support structure of the lens 1, used for fixing the lens 1, preventing dust and stains from entering the lens, and playing a role of light shielding and sealing. The support seat 3 is made of, for example, a plastic material such as polycarbonate (PC), acrylonitrile butadiene styrene (ABS), liquid crystal polymer (LCP), and polyamide (PA46 / PA66), which improves the overall performance of the support seat 3 and ensures stable operation.

[0045] A groove structure 31 is arranged on one side of the support seat 3 along the axial direction of the camera module, and is used to enhance the adhesion effect of the glue layer 4. The glue layer 4 is connected with the circuit board 2 and the support seat 3 respectively, and at least part of the structure of the glue layer 4 can be accommodated in the groove structure 31 of the support seat 3, so as to realize the engagement of the glue layer 4 and the support seat 3 and increase the firmness and stability of the connection.

[0046] In this embodiment, as shown in Figures 1-4 The support seat 3 includes a support body 33 and a connecting portion 32. The support body 33 is provided with a through hole 312 along the axial direction of the camera module, and the through hole 312 is used to mount the lens 1. The connecting portion 32 is located on the side of the support body 33 away from the lens 1, and the circumferential outer wall of the connecting portion 32 forms the groove structure 31. The connecting portion 32 protrudes from the support body 33 along the axial direction of the camera module. This design makes the groove structure 31 easier to process and position, and is also conducive to the uniform distribution and effective embedding of the glue layer 4.

[0047] In order to further enhance the adhesion effect of the groove structure 31, the connecting portion 32 includes a plurality of connecting branches 321 connected in sequence. The plurality of connecting branches 321 are, for example, enclosed in a rectangular shape, and the shape enclosed by the connecting branches 321 can refer to the radial cross-sectional shape of the support body 33 to meet the requirements.

[0048] The outer wall of each connecting branch 321 forms the groove structure 31. This multi-branch structure not only increases the number and distribution range of the groove structure 31, but also improves the overall strength of the support seat 3 through the mutual support between the connecting branches 321.

[0049] In this embodiment, as shown in Figures 1-4 In order to optimize the distribution and effect of the groove structure 31, the groove structure 31 includes a plurality of sub-grooves 311. The plurality of sub-grooves 311 are arranged in sequence and at intervals, which not only ensures the continuity of the groove structure 31, but also avoids the problems of processing difficulty and stress concentration caused by the excessive length of a single groove structure 31. In addition, the plurality of sub-grooves 311 can also increase the engagement effect with the glue layer 4 and improve the stability.

[0050] Exemplarily, the sub-groove 311 comprises a first groove surface 3111 and two second groove surfaces 3112. The two second groove surfaces 3112 are symmetrically arranged on both sides of the first groove surface 3111 to form a trapezoidal sub-groove 311, and the first groove surface 3111 and the second groove surface 3112 have a preset angle, such as 45°-60°, which not only increases the complexity of the groove structure 31, but also enhances the friction and adhesion area between the glue layer 4 and the support seat 3 by changing the direction of the groove surface, thereby further improving the firmness of the connection.

[0051] In the embodiment, as shown in the drawings, Figures 1-4 The glue layer 4 comprises a first glue body 41, a second glue body 42, and an occlusion part 43. The second glue body 42 is connected with the first glue body 41, and the second glue body 42 is arranged around the first glue body 41 to form a ring shape, and the second glue body 42 is bonded with the support body 33 of the support seat 3.

[0052] The occlusion part 43 is connected with the first glue body 41, the first glue body 41 is connected with the circuit board 2, and the occlusion part 43 is embedded into the groove structure 31 of the support seat 3, which not only increases the strength and stability of the glue layer 4, but also further enhances the firmness of the connection through the embedding effect of the occlusion part 43 and the groove structure 31.

[0053] Exemplarily, in order to optimize the distribution and effect of the occlusion part 43, the occlusion part 43 comprises a plurality of first occlusion bodies 431, which are arranged in sequence and spaced apart along the circumferential inner wall of the second glue body 42, which not only ensures the continuity of the occlusion part 43, but also avoids the problems of processing difficulty and stress concentration caused by too dense occlusion part 43. Among them, the first occlusion body 431 corresponds to the above-mentioned sub-groove 311 one by one, and the first occlusion body 431 can be bonded with the first groove surface 3111 and the second groove surface 3112. The first occlusion body 431 is a convex structure, and the sub-groove 311 is a concave structure. When they are connected, they form a state of occlusion, which not only increases the contact area, but also realizes the state of interlocking, thereby further improving the firmness of the connection.

[0054] The camera module in the embodiment is provided with a groove structure 31 on the side connected with the circuit board 2 of the support seat 3, and the groove structure 31 has a plurality of sub-grooves 311 arranged on the four side walls of the connecting part 32. When the glue layer 4 is filled into the sub-groove 311 in a fluid state, the glue layer 4 and the sub-groove 311 of the support seat 3 form a state of interlocking teeth. Compared with the straight edge structure in the related art, the embodiment increases the bonding area of the side surface of the support seat 3, thereby increasing the bonding strength of the support seat 3 and the circuit board.

[0055] And the support seat 3 is provided with sub-slots 311 in both transverse and longitudinal directions, and when the adhesive layer 4 is filled into the sub-slots 311 in a fluid state, the adhesive layer 4 in the transverse sub-slots 311 can withstand transverse shear force, and the adhesive layer 4 in the longitudinal sub-slots 311 can withstand longitudinal shear force, thereby reducing the risk of adhesive separation of the support seat 3.

[0056] Second embodiment

[0057] The second embodiment has the same or similar basic structure as the first embodiment, and the difference lies in the structure between the support seat 3 and the adhesive layer 4. Further exemplary descriptions are made below to better understand the scheme in this embodiment.

[0058] In this embodiment, as shown in Figure 1 , Figures 5-7 , the side of the support seat 3 away from the lens 1 is provided with a containing space 34, and the inner side wall of the containing space 34 forms a groove structure 31. This design enables the adhesive layer 4 to be embedded more deeply inside the support seat 3, thereby further improving the stability and firmness of the connection.

[0059] The groove structure 31 includes a plurality of sub-slots 311, and the plurality of sub-slots 311 are arranged at intervals along the circumferential inner side wall of the containing space 34. The sub-slots 311 include first groove faces 3111 and second groove faces 3112, and the arrangement manner is the same as that in the first embodiment, which will not be repeated here.

[0060] In this embodiment, as shown in Figure 1 , Figures 5-7 , the adhesive layer 4 includes a first adhesive 41, a second adhesive 42, and a clamping portion 43. The arrangement manner of the first adhesive 41 and the second adhesive 42 is the same as that in the first embodiment, which will not be repeated here. The difference lies in that the clamping portion 43 includes a plurality of second clamping bodies 432, and the plurality of second clamping bodies 432 are arranged at intervals along the circumference of the second adhesive 42. The plurality of second clamping bodies 432 are located on the inner side of the second adhesive 42 and have a preset distance from the second adhesive 42. This design not only increases the number and distribution range of the clamping portion 43, but also adjusts the distance between the clamping portion 43 and the second adhesive 42 to clamp part of the structure of the support seat 3 between the clamping portion 43 and the second adhesive 42, thereby further optimizing the stability and firmness of the connection.

[0061] In this embodiment, the support seat 3 is internally provided with the groove structure 31, i.e., the inner side wall of the containing space 34, and a plurality of sub-slots 311 are arranged, so that the adhesive layer 4 and the support seat 3 form an interlocking state inside, and the adhesive layer 4 can be embedded more deeply inside the support seat 3, thereby further improving the stability and firmness of the connection and increasing the bonding strength between the support seat 3 and the circuit board 2.
