DETAILED DESCRIPTION

[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings of the embodiments of the utility model. The embodiments described below are exemplary and are used for explaining the utility model, and cannot be understood as the limitation of the utility model.

[0026] The embodiments of the utility model will be described according to the overall structure of the utility model.

[0027] A full sealing type camera module structure, like Figures 1 to 6As shown, comprising a chassis 100, the top center of the chassis 100 is mounted with a camera 130, the outer side of the camera 130 is sleeved with a protective shell 120 which is inserted with the top end of the chassis 100, the edge of the protective shell 120 is equipped with a positioning assembly 110 at the top end of the chassis 100;

[0028] The positioning assembly 110 comprises a fixed L-shaped ring 111 at the top end of the chassis 100, the outer wall of the fixed L-shaped ring 111 is rotationally connected with a movable L-shaped ring 112, the inner wall of the movable L-shaped ring 112 is fixed with a plurality of arc blocks 113 above the fixed L-shaped ring 111, the inner side of each arc block 113 is slidably provided with a positioning rod 114 which penetrates through the fixed L-shaped ring 111 and extends into the protective shell 120, one end of the positioning rod 114 extends into the arc block 113, an extrusion groove 116 is formed at the contact position between the curved inner wall of the arc block 113 and the positioning rod 114, one side of each arc block 113 is provided with a piston cylinder 118 which is fixed with the top end of the fixed L-shaped ring 111, a piston 117 is slidably arranged in the piston cylinder 118, the end face of the piston 117 is provided with a piston rod 119 which extends out of the piston cylinder 118 and is fixed with the arc block 113;

[0029] A circular channel is formed at the contact position between the fixed L-shaped ring 111 and the positioning rod 114, the outer wall of the positioning rod 114 is provided with a spring 115, and the two ends of the spring 115 are fixed with the positioning rod 114 and the fixed L-shaped ring 111 respectively;

[0030] A first ring groove 101 is formed at the contact position between the top end of the chassis 100 and the protective shell 120, a butt joint ring 102 is fixed in the first ring groove 101, and a plurality of air bag rings 103 are fixed on the curved inner and outer walls of the butt joint ring 102.

[0031] Firstly, the camera 130 is installed at the center of the top of the chassis 100, then an external force is applied to the movable L-shaped ring 112 to make it rotate around the center of the chassis 100, and the plurality of arc blocks 113 are synchronously rotated, at this time the extrusion groove 116 no longer generates a centripetal extrusion force on the end of the positioning rod 114, and the spring 115 releases the pressure to make the positioning rod 114 move close to the movable L-shaped ring 112, then the protective shell 120 is sleeved and the bottom end is sleeved with the outer wall of the butt joint ring 102, finally the external force applied to the movable L-shaped ring 112 is removed, and the extrusion groove 116 formed in the arc block 113 again generates a transverse centripetal extrusion force on the positioning rod 114, making the positioning rod 114 move and the end enter the blind hole 121, thereby completing the locking effect of the protective shell 120;

[0032] When the dynamic L-shaped ring 112 is forced to rotate, it will drive the piston rod 119 to move in an arc trajectory through the arc block 113. At this time, the end of the piston 117 also moves inside the piston cylinder 118, and the air inside the air bag ring 103 is extracted to the piston cylinder 118, and vice versa. The air in the piston cylinder 118 is squeezed and delivered to the air bag ring 103, so that it fully contacts the second ring groove 122, ensuring that the protective shell 120 and the chassis 100 are sealed at the interface, thereby protecting the internal camera 130.

[0033] Please refer to Figure 5 The docking ring 102 is connected to the piston cylinder 118 through a conduit, which is hidden in the chassis 100.

[0034] The conduit can deliver the air inside the piston cylinder 118 to the air bag ring 103, so that it expands and becomes larger to seal the gap between the two, achieving better sealing effect.

[0035] Please refer to Figure 2 And Figure 3 The bottom end of the protective shell 120 is provided with a second ring groove 122 at the contact position with the docking ring 102, and the inner wall of the second ring groove 122 is provided with a matching sealing ring groove at the corresponding position of the air bag ring 103.

[0036] The second ring groove 122 and the docking ring 102 are inserted to make the gap at their interface in a non-horizontal state, which can better block the intrusion of moisture, and cooperate with the sealing ring groove to make it fully contact with the expanded air bag ring 103.

[0037] Please refer to Figure 5 The curved outer wall of the fixed L-shaped ring 111 is provided with a torsional spring near the top end of the chassis 100, and the two ends of the torsional spring extend into the dynamic L-shaped ring 112.

[0038] The torsional spring generates a reverse torsional force on the rotated dynamic L-shaped ring 112, which can automatically drive the dynamic L-shaped ring 112 to reverse and reset.

[0039] Please refer to Figure 1 , Figure 2 And Figure 3 The protective shell 120 is a double-layer structure, and the outer wall of the protective shell 120 is provided with a blind hole 121 at the contact position with the end of the positioning rod 114.

[0040] The double-layer structure of the protective shell 120 improves the protection effect of the internal camera 130,

[0041] The outer wall of the protective shell 120 is sprayed with a waterproof layer.

[0042] The waterproof layer forms a waterproof film containing a component, and the free radical of the chemical composition of the component is a non-hydrophilic group, so water droplets cannot adhere to the outer wall of the protective shell 120.

[0043] In use, firstly, the camera 130 is installed at the center of the top of the chassis 100, and then an external force is applied to the movable L-shaped ring 112 to make it rotate around the center of the chassis 100, and a plurality of groups of arc blocks 113 are synchronously rotated, at this time, the extrusion groove 116 no longer generates a centripetal extrusion force on the end of the positioning rod 114, and the spring 115 releases the pressure at this time to make the positioning rod 114 close to the movable L-shaped ring 112, and then the protective shell 120 is sleeved and the bottom end is sleeved and connected with the outer wall of the connecting ring 102, and finally the external force applied to the movable L-shaped ring 112 is removed, and the extrusion groove 116 opened by the arc block 113 generates a transverse centripetal extrusion force on the positioning rod 114 again, so that the positioning rod 114 moves and the end enters the blind hole 121, thereby completing the locking effect of the protective shell 120.

[0044] When the movable L-shaped ring 112 is forced to rotate, the piston rod 119 is moved in an arc trajectory through the arc block 113, at this time, the end of the piston 117 also moves in the piston cylinder 118, and the air in the airbag ring 103 is extracted into the piston cylinder 118, and vice versa, the air in the piston cylinder 118 is extruded and delivered to the airbag ring 103, so that it fully contacts the second ring groove 122, and the protective shell 120 and the chassis 100 are connected to ensure sealing, thereby protecting the internal camera 130, and the parts not involved in the device are the same as the prior art or can be realized by the prior art.

[0045] Although the embodiments of the present application have been shown and described, the specific embodiments are merely an explanation of the present application, and are not a limitation of the present application, and the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner, and those skilled in the art can make modifications, replacements and variations of the embodiments without creative contribution after reading the specification, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.
