Multiple glue injection path 31 is arranged along the circumferential direction of base 3 interval, and the glue injection port 311 of each glue injection path 31 is located at one end of base 3 away from magnet assembly 2, and the glue outlet 312 of each glue injection path 31 is towards the inner wall of cover 1, multiple guide grooves 34 are arranged at the outer periphery of base 3 interval, respectively with multiple glue outlet 312 one-to-one communication, the outlet end of guide groove 34 is towards the inner wall of cover 1, multiple overflow grooves 32 are arranged at the outer periphery of base 3 interval, respectively with multiple glue outlet 312 one-to-one communication, and the outlet end of overflow groove 32 is towards magnet assembly 2.

[0040] In the embodiment, the glue injection structure is arranged to facilitate the full circumference glue injection of the camera module and improve the glue injection effect. The glue injection structure includes glue injection paths 31, guide grooves 34 and overflow grooves 32. The glue injection paths 31, the guide grooves 34 and the overflow grooves 32 are arranged in multiple. The multiple glue injection paths 31 are arranged along the circumference of the base 3 to ensure that the glue is evenly distributed along the circumference of the base 3, thereby ensuring the glue injection effect between the base 3 and other components and improving the overall structural strength of the camera module. The glue injection ports 311 of the glue injection paths 31 are located at the end of the base 3 away from the magnet assembly 2, so that the camera module does not need to be flipped for operation to improve the convenience of the glue injection operation. The glue outlets 312 of the glue injection paths 31 are all directed towards the inner wall of the shielding cover 1 to ensure that the glue can reach the shielding cover 1 through the glue outlets 312, thereby improving the connection strength between the base 3 and the shielding cover 1.

The outlet end of the overflow groove 32 is directed towards the magnet assembly 2, so that the glue in the glue injection path 31 can reach the magnet assembly 2 through the overflow groove 32 to achieve bonding and fixing, thereby ensuring the glue injection effect. Through the above arrangement, the camera module of the embodiment can facilitate the glue injection operation, improve the glue injection effect and operation efficiency.

[0041] The specific structure of the camera module will be described below.

[0042] Specifically, as shown in Figures 1-6 The capillary path 35 is arranged between the shielding cover 1 and the base 3. The capillary path 35 is in communication with the guide grooves 34, so that the glue in the guide grooves 34 can reach the capillary path 35 under capillary action, thereby further improving the glue injection effect between the shielding cover 1 and the base 3.

[0043] Specifically, as shown in Figures 3-8 The glue injection path 31 is provided with a buffer step 33. The buffer step 33 is arranged at an angle with the extension direction of the glue injection path 31. When the glue flows onto the buffer step 33, the flow speed of the glue can be slowed down, so that the glue flows more smoothly in the glue injection path 31 and is more evenly distributed, thereby improving the glue injection effect.

[0044] More specifically, the buffer steps 33 are provided in plurality, and the plurality of buffer steps 33 are arranged at intervals along the extension direction of the glue injection passage 31, so as to gradually slow down the flow speed of the glue, and further improve the uniform diffusion of the glue in the glue injection passage 31. From the direction of the glue injection port 311 to the glue outlet port 312, the area of the plurality of buffer steps 33 gradually decreases, so as to optimize the flow path of the glue, and ensure that the glue can accurately flow to the glue outlet port 312, thereby improving the glue dispensing effect. Moreover, the buffer steps 33 are provided with inclined surfaces, so as to facilitate the flow and diffusion of the glue.

[0045] Specifically, as shown in Figures 5-10 the opening size of the guide groove 34 gradually increases from the inner wall away from the shielding cover 1 to the inner wall close to the shielding cover 1. With the gradual increase of the opening size of the guide groove 34, the glue can flow more smoothly to the inner wall of the shielding cover 1 and achieve large-area coverage, which is conducive to improving the glue dispensing effect between the base 3 and the shielding cover 1.

[0046] Specifically, the glue overflow groove 32 is provided with a diameter expansion part 321, and the outlet end of the glue overflow groove 32 is arranged at the diameter expansion part 321. When the glue passes through the diameter expansion part 321, the opening size of the diameter expansion part 321 increases, so that the flow direction of the glue is adjusted and dispersed to a certain extent, which helps the glue to diffuse more uniformly between the base 3 and the magnet assembly 2, thereby improving the glue dispensing effect.

[0047] Specifically, as shown in Figures 1-12 the outer peripheral wall of the base 3 is provided with a glue pouring groove 36, and the outlet end of the glue pouring groove 36 faces the inner wall of the shielding cover 1. The glue pouring groove 36 and the inner wall of the shielding cover 1 form a glue pouring passage 361, so as to ensure that the glue can diffuse along the extension direction of the glue pouring passage 361, thereby ensuring the firm connection between the base 3 and the shielding cover 1.

[0048] More specifically, the glue pouring groove 36 is provided with a step part 362, and the step part 362 is arranged at an angle with the extension direction of the glue pouring groove 36. By arranging the step part 362, the flow speed of the glue can be gradually slowed down during the flow process, which not only reduces the air bubbles generated during the flow process of the glue and improves the glue dispensing effect, but also increases the contact area between the glue and the base 3, which is conducive to improving the connection strength.

[0049] More specifically, the glue pouring groove 36 is further provided with a guide part 363, which gradually approaches the inner wall of the shielding cover 1 in the direction close to the magnet assembly 2, so as to ensure that the glue can gradually approach the magnet assembly 2 along the guide part 363 during the flow process, thereby improving the accuracy and uniformity of the filling.

[0050] Specifically, the glue injection grooves 36 are provided in plurality, and the plurality of glue injection grooves 36 are arranged at intervals along the circumference of the base 3, thereby increasing the contact area between the glue and other components, and improving the connecting strength between the base 3 and the shielding cover 1.

[0051] Specifically, as shown in Figures 1-4 the base 3 is provided with a first avoiding opening, and the shielding cover 1 is provided with a second avoiding opening, so as to provide sufficient space for the lens 5, and ensure that the lens 5 can be normally installed and adjusted in focus. The movable assembly 4 comprises a movable frame and a coil assembly arranged around the movable frame, and the movable frame is provided with a third avoiding opening. The magnet assembly 2 is arranged around the coil assembly, so as to ensure the normal use of the camera module. The front end of the lens 5 passes out of the third avoiding opening and the second avoiding opening in sequence, and the rear end of the lens 5 is exposed from the first avoiding opening, thereby ensuring the compactness and reliability of the overall structure of the camera module. The magnet assembly 2 comprises a plurality of magnet blocks, and the plurality of magnet blocks are arranged at intervals around the coil assembly. Through the interaction of the plurality of magnet blocks and the coil assembly, the moving direction and distance of the lens 5 can be accurately controlled, so as to realize the functions of automatic focusing, optical anti-shake and the like.

[0052] More specifically, the shielding cover 1 is provided with an assembly opening 12, and the assembly opening 12 and the second avoiding opening are arranged at the two ends of the shielding cover 1 respectively. The base 3 is connected to the assembly opening 12, so as to facilitate the mutual assembly of the base 3, the lens 5, the movable assembly 4, the magnet assembly 2 and the shielding cover 1, and improve the compactness of the overall structure of the camera module.

[0053] Moreover, as shown in Figures 1-12 the glue is injected into the glue injection channel 31, and the base 3, the magnet assembly 2 and the shielding cover 1 are bonded by means of the glue overflow groove 32, the guide groove 34 and the capillary channel 35, so as to avoid the additional dispensing operation on the magnet assembly 2, reduce the dispensing frequency, and prevent the glue from flowing onto the movable assembly 4 and the lens 5, thereby improving the dispensing effect and work efficiency.

[0054] It should be noted that the glue of the embodiment includes but is not limited to epoxy resin, UV glue and AB glue, etc., as long as the dispensing effect between the base 3, the magnet assembly 2 and the shielding cover 1 can be ensured, and the specific material of the glue is not limited here.

[0055] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application. Here, it is not necessary and also impossible to enumerate all the implementation modes. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application claim.
