[specific embodiment]

The utility model is described in detail below with reference to Fig. 1 to Fig. 3.

As shown in Figure 1 to Figure 3, the utility model relates to a kind of lens module 100, the lens module 100 includes lens barrel 110 and the lens set 120 that is contained in the lens barrel 110, the lens barrel 110 include first for being provided with light hole 111a Wall 111 and the second barrel 112 extended from first barrel 111 bending, second barrel 112 include close to object side First connection wall 112a and the second connection wall 112b extended from the first connection wall 112a to image side, also, along institute In the circumferential direction for stating the second barrel 112, the first connection wall 112a is provided at least one being thinned to optical axis OO ' recess The wall thickness of portion 112a1, the thinning part 112a1 are less than the wall thickness of the second connection wall 112b.

The lens module 100 of the present embodiment structure can make that mirror can be made in injection molding 110 structure of lens barrel The mobility of the molding structure of cylinder 110 is more preferable, more stable, thus when lens set 120 to be assembled in lens barrel 110, Ke Yiti High assemble stable, improves the assembling yield of product, and then the overall performance of lens module 100 can be improved.

It should be noted that for thinning part 112a1, specifically thickness thinning is not defined, those skilled in the art Member can according to actual needs, thickness thinning required for determining, for example, can be according between molding mobility quality and wall thickness Relationship determine etc..

Explanation is needed further exist for, the particular number of thinning part 112a1 is not defined, art technology Personnel are in practical application, the quantity of required thinning part 112a1 can be determined, for example, the thinning part according to actual needs The quantity of 112a1 can be for 2,3 or multiple etc..

As shown in figures 1 and 3, second barrel 112 includes the first side wall 112c close to object side, the close to image side The third side wall 112e of two side wall 112d and the connection the first side wall 112c and second sidewall 112d, wherein described First connection wall 112a and the second connection wall 112b are arranged on the second sidewall 112d.

As shown in figures 1 and 3, the first connection wall 112a includes close to the object side 112a2 of object side and from the object side The lateral surface 112a3, the thinning part 112a1 that face 112a2 extends to image side bending is from the lateral surface 112a3 to close to institute The direction for stating optical axis OO ' is recessed the sunk structure to be formed.

In order to further such that in injection molding lens barrel 110, molding structure mobility is more preferable, more stable, such as Fig. 3 institute Show, the thinning part 112a1 extends upward through the first connection wall 112a in the side for being parallel to optical axis OO '.Certainly, the thinning part 112a1 can also and not through the first connection wall 112a, and be through predetermined depth, specifically can be determine according to actual needs.

In order to further such that in injection molding lens barrel 110, molding structure mobility is more preferable, more stable, such as Fig. 1 to figure Shown in 3, multiple thinning part 112a1 are provided on the first connection wall 112a, multiple thinning part 112a1 are along described The circumferential spaced set of first connection wall 112a.Certainly, multiple thinning part 112a1 is in addition to can be along first connection wall It, can also be using other some distribution modes, for example, multiple thinning part 112a1 other than the circumferential spaced set of 112a Circumferential spacing along the first connection wall 112a is incremented by successively, alternatively, multiple thinning part 112a1 are along first connection wall Circumferential random distribution of 112a etc..

As shown in Figure 1 to Figure 3,6 thinning part 112a1 are provided on the first connection wall 112a.Certainly, this is removed In addition, the thinning part 112a1 of other quantity also can be set on the first connection wall 112a, it is preferred that be provided with 4-6 and be thinned Portion.

As shown in Figure 1 to Figure 3, the lens set 120 includes the first eyeglass 121, the second eyeglass 122 and barn door 123, institute It states barn door 123 and is connected to the first connection wall 112a.

The lens module 100 of the present embodiment structure, the barn door 123 is connected to the first connection wall 112a, in this way, passing through The set thinning part 112a1 on the first connection wall 112a, can be effectively ensured the internal diameter circularity at the position, improve shading The stability that plate 123 and lens barrel 110 assemble, and then improve the assembling yield of product.

As shown in figure 3, the lens set 120 further includes folding positioned at the 121 object side of the first eyeglass and successively the third set Eyeglass 124, the 4th eyeglass 125 and the 5th eyeglass 126.Certainly, according to actual needs, those skilled in the art can also design more More or lesser amount of eyeglass, specifically can be determine according to actual needs.

Above-described is only the embodiments of the present invention, it should be noted here that for the ordinary skill of this field For personnel, without departing from the concept of the present invention, improvement can also be made, but these belong to it is practical Novel protection scope.
