Fig. 2 is the diagrammatic cross-section of module base provided by the utility model.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawings and examples.

As illustrated in fig. 1 and 2, a kind of camera module of side wall detent, including wiring board 4, sensor 3, module base 2 and mirror First 1, the sensor 3 is mounted on the wiring board 4, and the module base 2 is adhesively fixed on the wiring board 4 and covers Said sensor 3；The module base 2 has a light hole above the photosurface for corresponding to the sensor 3 and from institute It states light hole and extends upward a tubular construction 21, the camera lens 1 is assemblied in the tubular construction 21；The tubular construction 21 Inner sidewall on there is an at least L-shaped groove 22, the vertical slot 221 of the L-shaped groove 22 runs through the top of the tubular construction 21； There is at least one protrusion fixture block 13 corresponding with the L-shaped groove 22, the protrusion fixture block 13 blocks on the lateral wall of the camera lens 1 It connects in the transverse groove 222 of the L-shaped groove 22.

In assembly, firstly, the camera lens 1 is fitted into the tubular construction 21 from the top of the module base 2, At this point, the vertical slot 221 of corresponding L-shaped groove 22 from the tubular construction 21 of the protrusion fixture block 13 on the camera lens 1 drops to The corner of the L-shaped groove 22, then, by the camera lens 1 relative to the 21 relative rotation certain angle of tubular construction, so that The protrusion fixture block 13 is moved in the transverse groove 222 of corresponding L-shaped groove 22, and in this case, the protrusion fixture block 13 will block It connects in the transverse groove 222 of the L-shaped groove 22 and can not move up and down, the camera lens 1 would not take off out of described module base 2 It falls.

The camera module is by opening up L-shaped groove 22 on the tubular construction 21, so that the protrusion fixture block on the camera lens 1 13 can be connected in the transverse groove 222 in the L-shaped groove 22 in assembly, prevent the camera lens 1 due to moving up and down from institute It states and falls off in module base 2, realize stable non-threaded configurations assembly.

Equal non-threaded configurations on the lateral wall of the camera lens 1 and the inner sidewall of the tubular construction 21；The L-shaped groove 22 was both It can be groove structure (the non-hollow out of lateral wall of the tubular construction 21), be also possible to the empty slot structure (tubular construction 21 Lateral wall hollow out), depending on it is described protrusion fixture block 13 length and the tubular construction 21 wall thickness depending on.

222 end of transverse groove of the L-shaped groove 22 is a circular trough 223, and the camera lens 1 is relative to the tubular construction 21 After rotation, the protrusion fixture block 13 is finally connected in the circular trough 223；Preferably, the radius of the circular trough 223 is slightly Greater than the radius of the protrusion fixture block 13, so that the protrusion fixture block 13 has certain freedom degree in the circular trough 223, with Facilitate and carries out subsequent AA Alignment Process.

The camera lens 1 includes the head 11 and body portion 12 axially connected, and the radius on head 11 is greater than the radius in body portion 12, and Preferably, the radius on the head 11 is greater than the inside radius of the tubular construction 21；The protrusion fixture block 13 is located at the body portion On 12 lateral wall, the maximum outer radius that the body portion 12 of the camera lens 1 is constituted together with the protrusion fixture block 13 is greater than described The inside radius of tubular construction 21, i.e., when the length of multiple protrusion fixture blocks 13 is inconsistent, a longest protrusion fixture block 13 connects It is greater than the inside radius of the tubular construction 21 with the outer radius that the body portion 12 of the camera lens 1 is constituted together, just can guarantee in this way At least one protrusion fixture block 13 can be clamped with the L-shaped groove 22 on the tubular construction 21.

In institute between angle of eccentricity between multiple L-shaped grooves 22 on the tubular construction 21, with multiple protrusion fixture blocks 13 The angle of eccentricity stated on camera lens 1 is corresponding, and the transverse groove 222 of multiple L-shaped grooves 22 extends identical arc to same direction of rotation Degree.

In the present embodiment, the quantity of the L-shaped groove 22 and protrusion fixture block 13 is two, and two L-shaped grooves 22 are in the cylinder It is in 180 ° of offset alignments in shape structure 2121, and the transverse groove 222 of two L-shaped grooves 22 is identical along direction of rotation counterclockwise extension Radian, it is corresponding, two protrusion fixture blocks 13 on the camera lens 1 also be in 180 ° of offset alignments, with assembly when can be one by one It is corresponding.

In addition, the size between multiple L-shaped grooves 22 should be consistent as far as possible, i.e., the vertical slot 221 between multiple L-shaped grooves 22 Depth and 222 length of transverse groove are answered identical.

There is at least screw hole 23 through side wall on the side wall of the tubular construction 21, be screwed in the screw hole 23 The camera lens 1 is pressed on the inner sidewall of the tubular construction 21 by one screw 6, the screw 6；The inner sidewall of the screw hole 23 It is upper that there is internal screw thread, there is the external screw thread being screwed on the internal screw thread on the lateral wall of the screw 6.

The camera module each accessory after the assembly is completed, between the camera lens 1 and sensor 3 relative position carry out The camera lens 1, by screwing the screw 6 in the screw hole 23, is fixed on the tubular construction 21 after AA alignment by AA alignment It is interior, and the camera lens 1 elasticity fixed in the tubular construction 21 can be controlled by the screw 6.

More preferably, fixed by viscose 5 between the camera lens 1 and tubular construction 21, the viscose 5 is bonded in the camera lens Between 1 11 lower surface of head and the upper surface of the tubular construction 21.

The above-mentioned embodiments merely express the embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously Therefore it cannot be interpreted as that a limitation on the scope of the patent of the present invention, as long as using the form institute of equivalent substitution or equivalent transformation The technical solution of acquisition, shall fall within the scope of the present invention.
