[0015] Therefore, the cross section of the groove is substantially V-shaped structure by the stop wall and the inclined wall, which is convenient for filling and uniformity of the liquid sealant in the groove, and is conducive to improving the water blocking performance of the sealant. In addition, the above-mentioned setting can also improve the stability of the connection between the support and the lens seat.
[0016] In some embodiments, the central axis of the stop wall, the central axis of the inclined wall and the central axis of the mounting groove are coincidentally arranged.
[0017] Therefore, the central axis of the stop wall, the central axis of the inclined wall and the central axis of the mounting groove are coincidentally arranged, which can reduce the processing difficulty of the mounting groove and the groove, and is conducive to reducing the manufacturing cost of the support.
[0018] In some embodiments, a gap is provided between the inner wall of the mounting groove and the lens seat, the groove communicates with the gap, and part of the sealant is arranged in the gap.
[0019] Therefore, by filling the sealant in the gap between the inner wall of the mounting groove and the lens seat, the area of the sealant is expanded, which is conducive to improving the water blocking performance of the sealant.

[0027] In some embodiments, the projection profile of the support along the optical axis direction of the lens at least partially protrudes from the projection of the circuit board along the optical axis direction of the lens.
[0028] Therefore, the above settings allow the first adhesive layer to be completely attached to the bracket, preventing it from protruding from the circuit board and ensuring the aesthetics of the camera module.
[0029] In some embodiments, the camera module further includes:
[0030] A second adhesive layer is connected between the mirror mount and the circuit board, and the second adhesive layer is arranged around the circumference of the mirror mount.
[0031] Therefore, the second adhesive layer can achieve a seal between the lens mount and the circuit board, preventing water from entering the lens from between the lens mount and the circuit board, which helps to improve the waterproof performance of the camera module.
[0032] In some embodiments, along the optical axis of the lens, the end of the lens mount away from the circuit board protrudes from the end of the bracket away from the circuit board.

In the description of the present application, it should be noted that the meaning of "multiple" is two or more, unless otherwise explicitly specified and limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0045] The embodiments of the present application are described in detail below in combination with the drawings.
[0046] Please see Figures 1 to 3 The camera module 100 provided by the embodiments of the present application includes a circuit board 110, a photosensitive member 120, a lens holder 130, a lens 140, a bracket 150, and a sealing member 160. The photosensitive member 120 is arranged on the circuit board 110. The lens holder 130 is arranged on the circuit board 110 and forms an accommodating cavity 100a with the circuit board 110. The photosensitive member 120 is located in the accommodating cavity 100a. The lens 140 is mounted in the lens holder 130, and the image side of the lens 140 is arranged correspondingly to the photosensitive member 120. The bracket 150 is arranged on the circuit board 110 and is provided with a mounting groove 150a. The bracket 150 is sleeved on the lens holder 130 through the mounting groove 150a. The inner wall of the end of the mounting groove 150a away from the circuit board 110 is provided with a groove 150b. The groove 150b is arranged around the circumferential side of the bracket 150. The sealing member 160 is filled in the groove 150b to connect the lens holder 130 and the bracket 150.
[0047] Therefore, in the camera module 100, the lens holder 130 and the photosensitive element 120 are limited in the bracket 150, and the sealing member 160 is filled in the groove 150b between the bracket 150 and the lens holder 130 to fix the bracket 150 and the lens holder 130 and isolate the inside of the bracket 150 from the outside, which is conducive to improving the waterproof performance of the camera module 100.
[0048] It should be noted that the sealing member 160 can be formed by injecting glue into the groove 150b after the bracket 150 and the lens holder 130 are assembled. The liquid glue forming the sealing member 160 will be deformed by heat shrinking, so as to completely fill the groove 150b.
[0049] Please refer to Figure 2 and Figure 3 In some embodiments, the groove 150b includes a stop wall 150c and an inclined wall 150d. The stop wall 150c is arranged around the periphery of the bracket 150, and the inclined wall 150d is connected to one end of the stop wall 150c close to the photosensitive element 120 and is arranged around the periphery of the bracket 150. The distance between the inclined wall 150d and the lens holder 130 gradually decreases from the direction in which the stop wall 150c points to the photosensitive element 120.
[0050] Therefore, the cross section of the groove 150b is approximately V-shaped by the stop wall 150c and the inclined wall 150d, which facilitates the filling of the liquid sealing member 160 and the uniformity of the part in the groove 150b, and is conducive to improving the water blocking performance of the sealing member 160. In addition, the above arrangement can also improve the stability of the connection between the bracket 150 and the lens holder 130.
[0051] Please refer to Figure 3 In some embodiments, the center axis of the stop wall 150c, the center axis of the inclined wall 150d, and the center axis of the mounting groove 150a are arranged coincidentally.
[0052] Therefore, the center axis of the stop wall 150c, the center axis of the inclined wall 150d, and the center axis of the mounting groove 150a are arranged coincidentally, which can reduce the processing difficulty of the mounting groove 150a and the groove 150b, and is conducive to reducing the manufacturing cost of the bracket 150.
[0053] Please refer to Figure 2 and Figure 3 In some embodiments, a gap 100b is provided between the inner wall of the mounting groove 150a and the lens holder 130, the groove 150b communicates with the gap 100b, and part of the sealing member 160 is arranged in the gap 100b.
[0054] Therefore, by filling the seal 160 in the gap 100b between the inner wall of the mounting groove 150a and the lens seat 130, the area of the seal 160 is enlarged, which is conducive to improving the water blocking performance of the seal 160. In addition, the above-mentioned arrangement can also improve the connection strength between the support 150 and the lens seat 130.
[0055] Please refer to Figure 2 In some embodiments, the support 150 includes a main body 151 and a plurality of mounting bodies 152. The main body 151 is provided with a mounting groove 150a, and the plurality of mounting bodies 152 are connected to the outer side of the main body 151 and are arranged in a circumferential direction of the main body 151. The plurality of mounting bodies 152 are used to connect external components to fix the camera module 100.
[0056] Therefore, the plurality of mounting bodies 152 can realize the connection between the camera module 100 and the external components, which is conducive to improving the installation convenience of the camera module 100.
[0057] Please refer to Figure 2 and Figure 3 In some embodiments, the camera module 100 further includes a first adhesive layer 170. The first adhesive layer 170 is connected between the support 150 and the circuit board 110, and the first adhesive layer 170 is arranged in a circumferential direction of the support 150.
[0058] Therefore, the first adhesive layer 170 can realize the sealing between the support 150 and the circuit board 110 to block water from entering the inside of the support 150 from between the support 150 and the circuit board 110, which is conducive to improving the waterproof performance of the camera module 100.
[0059] In some embodiments, the projection profile of the support 150 in the optical axis direction of the lens 140 at least partially protrudes from the projection of the circuit board 110 in the optical axis direction of the lens 140.
[0060] Therefore, by the above-mentioned arrangement, the first adhesive layer 170 can be completely attached to the support 150, avoiding the first adhesive layer 170 protruding from the circuit board 110, which is conducive to ensuring the aesthetic appearance of the camera module 100.
[0061] Please refer to Figure 2 and Figure 3 In some embodiments, the camera module 100 further includes a second adhesive layer 180. The second adhesive layer 180 is connected between the lens seat 130 and the circuit board 110, and the second adhesive layer 180 is arranged in a circumferential direction of the lens seat 130.
[0062] Therefore, the second adhesive layer 180 can realize the sealing between the lens seat 130 and the circuit board 110 to prevent water from entering the lens 140 from between the lens seat 130 and the circuit board 110, which is conducive to improving the waterproof performance of the camera module 100.
[0063] In some embodiments, the lens holder 130 protrudes away from the one end of the circuit board 110 further than the bracket 150 does.
[0064] Therefore, the above arrangement can avoid the bracket 150 interfering with the installation of the camera module 100, and is conducive to miniaturization of the camera module 100.
[0065] Please refer to Figure 4 The embodiments of the present application also provide an electronic device 1000, which comprises a housing 200 and the camera module 100 described above, and the camera module 100 is installed in the housing 200. The electronic device 1000 can be a mobile phone, a tablet computer, etc.
[0066] In the electronic device 1000 described above, the lens holder 130 and the photosensitive member 120 are both limited in the bracket 150, and the sealing member 160 is filled in the groove 150b between the bracket 150 and the lens holder 130 to achieve fixation of the bracket 150 and the lens holder 130, and isolation of the inside of the bracket 150 from the outside, which is conducive to improving the waterproof performance of the electronic device 1000.
