## Abstract

A lens module is disclosed. The lens module includes a lens barrel having a first bonding face; a first lens; and a fixing component installed inside the lens barrel and including a second bonding face. At least one the first bonding face and the second bonding face is configured to be lumpy, and the first bonding face and the second bonding face are bonded by glue. The first bonding face, the second bonding face and the glue form a bonding structure.

## Claims

### Claim 1

A lens module including:
a lens barrel having a first bonding face;
a first lens;
a fixing component installed inside the lens barrel and including a second bonding face; wherein
at least one the first bonding face and the second bonding face is configured to be lumpy, and the first bonding face and the second bonding face are bonded by glue, and the first bonding face, the second bonding face and the glue form a bonding structure.

### Claim 2 (depends on 1)

The lens module as described in claim 1, wherein the lens barrel comprises a first barrel wall having an optical aperture and a second barrel wall extending from the first barrel wall, and the first bonding face locates the second barrel wall.

### Claim 3 (depends on 2)

The lens module as described in claim 2, wherein the first bonding face includes a plurality of first lugs and first grooves arranged in an array.

### Claim 4 (depends on 3)

The lens module as described in claim 3, wherein the second bonding face includes a plurality of second lugs and second grooves arranged in an array.

### Claim 5 (depends on 4)

The lens module as described in claim 4, wherein the sum of the side length of the first lug vertical to the optical axis and the side length of the first groove vertical to the optical axis is equal to the sum of the side length of the second lug vertical to the optical axis and the side length of the second groove vertical to the optical axis.

### Claim 6 (depends on 5)

The lens module as described in claim 5, wherein the fixing component is provided with an optical aperture, the outer side of the fixing component is provided with a first bevel face, the second bonding face serves as the first bevel face.

### Claim 7 (depends on 6)

The lens module as described in claim 6, wherein an angle between the first bevel face and the optical axis is θ1 and meets the following condition 0°≦θ1≦80°.

### Claim 8 (depends on 7)

The lens module as described in claim 7, wherein an angle between a projection of the side of the second lug not vertical to the optical axis on the surface vertical to the optical axis and the connecting line between the outer side endpoint of the projection and the axis is θ2, meeting 0°≦θ2≦80°.

### Claim 9 (depends on 8)

The lens module as described in claim 8, wherein the projection length of the first bevel face on the second barrel wall is two-thirds of the projection length of the entire fixing component on the second barrel wall.

### Claim 10 (depends on 1)

The lens module as described in claim 1 further comprising at least one second lens located in the lens barrel, the second lens locates at an object side or an image side of the first lens.
