1222, lens barrel 11 includes the first inner wall 111 abutted with outer edge surface 1223, is arranged in the first inner wall 111 close to object side one
Second inner wall 112 at end and the first extended surface 113 for connecting the first inner wall 111 and the second inner wall 112, in first
The distance that wall surface 111 arrives optical axis OO' arrives the distance of optical axis OO' less than the second inner wall 112, and object side 1221 includes from outer edge surface
1223 the first joint face 1221a extended close to the edge of object side towards the direction optical axis OO', the first joint face 1221a prolong than first
Face 113 is stretched closer to object side.
The utility model embodiment in terms of existing technologies, due to the first joint face 1221a and outer edge surface 1223
Junction flash can be generated during injection molding, abutted by setting outer edge surface 1223 with lens barrel 11, thus lens barrel
11 first eyeglasses 12 that support that can be consolidated do not have deckle-edged position；It include being abutted with outer edge surface 1223 by setting lens barrel 11
The first inner wall 111, be arranged in the first inner wall 111 close to second inner wall 112 of object side one end and connection first in
First extended surface 113 of wall surface 111 and the second inner wall 112, the first inner wall 111 to optical axis OO' distance less than second in
Wall surface 112 arrives the distance of optical axis OO', object side 1221 include from outer edge surface 1223 close to object side edge towards the direction optical axis OO'
Extend the first joint face 1221a, the first joint face 1221a than the first extended surface 113 closer to object side, thus first extension
The object side in face 113 has reserved certain space to accommodate eyeglass in the junction of the first joint face 1221a and outer edge surface 1223
Flash, effectively prevent the first eyeglass 12 flash and 11 inner wall of lens barrel interference, block and lead to the problem of not being easily assembled, mention
The high yield of lens module 100.
Preferably, lens barrel 11 further includes in the third inner wall 114 of 111 image side of the first inner wall and connection third
Second extended surface 115 of wall surface 114 and the first inner wall 111, image side surface 1222 include the side from outer edge surface 1223 close to image side
The second joint face 1222a, the second joint face 1222a that edge extends towards the direction optical axis OO' is than the second extended surface 115 closer to object
Side, the distance of the first inner wall 111 to optical axis OO' are greater than the distance that third inner wall 114 arrives optical axis OO'.So set,
The object side of two extended surfaces 115 has reserved certain space to accommodate eyeglass in the second joint face 1222a and outer edge surface 1223
The flash of junction has further prevented the flash of eyeglass and 11 inner wall of lens barrel to interfere, block and lead to the problem of not being easily assembled,
Improve the yield of lens module 100.
Worth one is mentioned that, lens module 100 further includes the second eyeglass 13 for being fixed on 12 image side of the first eyeglass, second
Eyeglass 13 is abutted with third inner wall 114, is folded with anti-dazzling screen 14 between the first eyeglass 12 and the second eyeglass 13.Further,
Anti-dazzling screen 14 compares the second extended surface 115 closer to object side.
In present embodiment, the material of the first eyeglass 12 is plastic cement (such as polycarbonate), and the first eyeglass of plastic cement 12 has light
Thin advantage, it is easy to carry；The specific coatings of the first eyeglass of plastic cement 12 improve the first eyeglass 12 with anti-scratch characteristic
Service life；Also, the reflective layer of the first eyeglass of plastic cement 12 can also allow the transparency of the first eyeglass 12 higher than glass, light transmission
Rate reaches 99%, to improve image quality.
In present embodiment, the first extended surface 113 is extended to from the first inner wall 111 along the direction perpendicular to optical axis OO'
Second inner wall 112, so set, it is conveniently stripped, be conducive to the manufacturing of lens barrel 11, meanwhile, it is capable to which lens barrel 11 is avoided to go out
Show the problem that right angle is bent and stress is excessive, improves the structural strength of lens barrel 11.
It is noted that the second extended surface 115 prolongs along the direction close to optical axis OO' towards image side from the first inner wall 111
Third inner wall 114 is extended to, so set, 11 internal diameter of lens barrel is at the second extended surface 115 by lesser second inner wall 112
Internal diameter increases to the internal diameter of biggish first inner wall 111 suddenly, can be flash compared to 11 internal diameter of lens barrel gradually changed
Reserved bigger accommodating space, avoids larger-size flash.
In present embodiment, the first joint face 1221a from outer edge surface 1223 close to object side edge along perpendicular to optical axis OO'
Direction towards optical axis OO' extend.It is understood that the first joint face 1221a is also possible to from outer edge surface 1223 close to object side
Edge along other directions towards optical axis OO' extend.
Specifically, lens module 100 further includes the optical module 15 that 12 object side of the first eyeglass is arranged in, object side 1221
It further include the abutment face 1221b being resisted against on optical module 15 and the first joint face 1221a of connection and abutment face 1221b
Transition face 1221c.In present embodiment, abutment face 1221b is vertical with optical axis OO'.It is noted that transition face 1221c is certainly
First joint face 1221a extends along the direction close to optical axis OO' towards object side close to the edge of optical axis OO', so set, convenient de-
Mould, is conducive to the manufacturing of lens barrel 11, meanwhile, it is capable to which lens barrel 11 is avoided the problem that right angle is bent and stress is excessive occur, mentions
The structural strength of high lens barrel 11.
It will be understood by those skilled in the art that the respective embodiments described above are to realize the specific implementation of the utility model
Example, and in practical applications, can to it, various changes can be made in the form and details, without departing from the spirit of the utility model
And range.
