Fig. 5 illustrates a partial cross-sectional view of a camera module 200 according to an exemplary embodiment of the present disclosure. Referring to fig. 5, the camera module 200 includes: bracket 210, lens module 220, housing 230, and sealing member 240. The bracket 210 is formed with a receiving cavity 211. The lens module 220 is assembled in the accommodating cavity 211, the lens module 220 includes a shooting end 221, and the shooting end 221 protrudes out of the accommodating cavity 211. The housing 230 includes a housing body 231 and a positioning boss 232 protruding from the surface of the housing body 231, the positioning boss 232 is provided with a positioning hole 233, the positioning hole 233 is sleeved on the shooting end 221, the housing body 231 includes a first region 234 and a second region 235 connected with each other, and the second region 235 protrudes toward the bracket 210 to form a first reinforcing portion 236. The seal 240 is sealingly disposed on a side of the first region 234 facing the bracket 210.

In the embodiment of the disclosure, the bracket 210 may form one or more accommodating cavities 211, and each accommodating cavity 211 is assembled with one lens module 220. Accordingly, the housing 230 includes one or more positioning holes 233 in the same number as the lens modules 220. In some embodiments, the sealing member 240 comprises foam, which is inexpensive and has good sealing properties without damaging other components. The sealing member 240 can prevent dirt such as dust from entering the accommodating cavity 211 to affect the light of the lens module 220. The lens module 220 includes a lens, a photosensitive element, and the like, and can perform a photographing function.

In the camera module 200 according to the embodiment of the present disclosure, the second region 235 of the housing body 231 protrudes toward the bracket 210 to form the first reinforcing portion 236, and the sealing member 240 is sealed at a side of the first region 234 facing the bracket 210, so that when an impact is applied to an end of the positioning boss 232 protruding from the housing body 231, a stable hard support is formed between the first reinforcing portion 236 and the bracket 210, and the first region 234 of the housing body 231 is prevented from excessively pressing the sealing member 240 to deform toward the lens module 220 due to the impact, so as to effectively protect the lens module 220.

In some embodiments, with continued reference to fig. 5, the first region 234 is located between the second region 235 and the positioning boss 232, and the sealing member 240 may seal between the first region 234 and the lens module 220. It is understood that the first region 234 is closer to the axis of the lens module 220 than the second region 235. In some embodiments, in this way, the first reinforcing portion 236 acts as a limit for the sealing element 240, and can effectively prevent dirt such as external dust, liquid, and the like from contaminating the lens module 220 through the sealing element 240, which is beneficial for the sealing element 240 to stably seal. In addition, the sealing member 240 is disposed inside, which is also beneficial to the beauty of the camera module 200.

In some embodiments, a gap is formed between first stiffener 236 and bracket 210. In some embodiments, when the end of the positioning boss 232 is impacted, the housing 230 moves towards the bracket 210 and presses the sealing member 240, the sealing member 240 buffers the housing 230, and when the first reinforcing portion 236 abuts against the bracket 210 to form a hard support, the housing 230 cannot move towards the bracket 210, so as to prevent the housing 230 from being deformed by sinking towards the lens module 220. In addition, the gap between the first reinforcement part 236 and the bracket 210 also facilitates the assembly therebetween.

In some embodiments, the first reinforcement part 236 is disposed around the lens module 220. It can be understood that the lens modules 220, the positioning holes 233 and the accommodating cavities 211 are arranged in a one-to-one correspondence. Illustratively, the number of the lens modules 220 is one, and the first reinforcement part 236 is disposed around one lens module 220. Illustratively, the number of the lens modules 220 is plural, and one first reinforcement part 236 is disposed around the plural lens modules 220. Illustratively, the number of the lens modules 220 is plural, and each lens module 220 is surrounded by a first reinforcement part 236. In this way, the first reinforcing portion 236 can effectively form a stable hard support with the bracket 210, and the housing body 231 is prevented from excessively pressing the sealing member 240 to be recessed toward the lens module 220 under the impact force.

In some embodiments, the interface between the first stiffener 236 and the bracket 210 is planar to facilitate a stable, stiff support therebetween. In other embodiments, the first reinforcement part 236 protrudes outward facing the bracket 210 to form a curved surface to prevent the first reinforcement part 236 from wearing the bracket 210.

In some embodiments, with continued reference to fig. 5, the camera module 200 further includes a transparent cover 250 covering the shooting end 221 of the lens module 220 to protect the lens module 220.
