Each embodiment of type is explained in detail.However, it will be understood by those skilled in the art that each in the utility model
In embodiment, many technical details are proposed in order to make reader more fully understand the utility model.But even if without this
A little technical details and various changes and modifications based on the following respective embodiments, also may be implemented each claim of the utility model
Technical solution claimed.
The first embodiment of the utility model is related to a kind of lens module 100, as shown in Figure 1, comprising: lens barrel 1 and
The eyeglass 2 being contained in lens barrel 1, lens barrel 1 include enclosing to set the first barrel 11 to form light hole 10 and from 11 court of the first barrel
The second barrel 12 that image side bending extends, the second barrel 12 of lens barrel 1 include: close to object side first part 121 and be located at the
The second part 122 of the image side of a part 121, the average thickness of first part 121 are less than the average thickness of second part 122,
And first part 121 includes the first outer surface 1202 of the first inner surface 1201 and separate optical axis OO` close to optical axis OO`, and
First outer surface 1202 is sticked and has metal sleeve 3.
The utility model embodiment in terms of existing technologies, passes through thickness average on the second barrel 12 of lens barrel 1
Degree is less than on the first outer surface 1202 of the first part 121 of second part 122 metal sleeve 3 that is sticked, so that lens barrel 1 is in high temperature
After solidification, 1 wall thickness of lens barrel it is relatively thin place due to metal sleeve 3 protection and enhance the integral strength of lens barrel 1 so that lens barrel
It is less prone to deformation, the ability that lens barrel 1 resists deformation is improved, to improve the performance of lens module 100.
The realization details of present embodiment is specifically described below, the following contents is only for convenience of the realization for understanding offer
Details, rather than implement the necessary of this programme.
The relatively thin first part 121 of 12 average wall thickness of the second barrel of lens barrel 1 includes: from the first barrel in present embodiment
11 bend extension and first vertical component effect 1211 vertical with the first barrel 11 towards image side, from the first vertical component effect 1211 along far from optical axis
The rake 1212 that the direction of OO` extends to image side inclination.
As shown in Figure 1,3 part of metal sleeve covers the first vertical component effect 1211 and rake 1212 in present embodiment.
Specifically, 3 part of metal sleeve covers the first vertical component effect 1211 and part covering rake 1212, metal sleeve 3
May be disposed at the position that the first vertical component effect 1211 and rake 1212 connect and to the direction far from joint extend one section away from
From, since wall thickness is relatively thin at first vertical component effect 1211 and rake 1212 connect in first part 121 position, it is infusing
Metal sleeve 3 is set at the position that the first vertical component effect 1211 and rake 1212 connect during modeling, so that lens barrel 1 and metal
Sleeve 3 be integrally formed so that 1 first part of lens barrel, 121 wall thickness it is relatively thin place by metal sleeve 3 protection be not easy deformation, meanwhile,
Only part covers the first vertical component effect 1211 and rake 1212, reduces metal materials, reduces cost.
Further, second part 122 is that bending extends and with first from rake 1212 to image side in present embodiment
The second vertical vertical component effect 122 of barrel 11.
It is worth noting that lens barrel 1 and metal sleeve 3 are integrally formed in injection moulding process in present embodiment, enhance
The fastness of lens module 100.
The second embodiment of the utility model is related to a kind of lens module 200, as shown in Fig. 2, it includes component with
Component in first embodiment is roughly the same, is in place of the main distinction, and metal sleeve 3 is completely covered the in present embodiment
One vertical component effect 1211 and rake 1211.
That is, other than covering metal sleeve 3 at the position that the first vertical component effect 1211 and rake 1212 connect,
Also in the metal sleeve of covering elsewhere 3 of first part 121, in this way, the place relatively thin in 1 first part of lens barrel, 121 wall thickness
When deformation occurs, the metal sleeve of the thicker place covering of 121 wall thickness of first part has shared a part of deformation power, so that lens barrel
1 first part 121 resists deformability more preferably, provides more comprehensive, effective reinforcing effect.
The third embodiment of the utility model is related to a kind of lens module 300, as shown in figure 3, it includes component with
Component in first embodiment is roughly the same, mainly thes improvement is that, the second vertical component effect 122 includes leaning in present embodiment
Second outer surface 1204 of the second inner surface 1203 of dipped beam axis and separate optical axis, 3 part of metal sleeve cover the second outer surface
1204。
Specifically, metal sleeve 3 from first part 121 extend a part covering second part 122 (i.e. second hang down
Straight portion) the second outer surface 1204 so that the area of metal sleeve 3 is bigger, so set, make the barrel of lens barrel 1 by
When deformation power, the power for being distributed to 3 various pieces of metal sleeve is smaller, to improve the ability that lens barrel 1 resists deformation.
4th embodiment of the utility model is related to a kind of lens module 400, as shown in figure 4, it includes component with
Component in third embodiment is roughly the same, is in place of the main distinction, and metal sleeve 3 is completely covered the in present embodiment
Two outer surfaces 1204.
Specifically, the outer surface of lens barrel 1 is made to be all covered with metal sleeve 3, so that the area of metal sleeve 3 is bigger,
So set, making the barrel of lens barrel 1 when by deformation power, the power for being distributed to 3 various pieces of metal sleeve is smaller, to mention
High lens barrel 1 resists the ability of deformation.
It should be noted that the second part 122 of second barrel 12 of lens barrel 1 is often set in some lens modules 400
Fluted, therefore, when metal sleeve 3 is arranged, metal sleeve 3 should agree with the groove of second part 122, be close to second part
122 outer surface.Certain lens barrel 1 or non-threaded lens barrel, to be provided to make the lens module with metal sleeve 3
It is convenient.
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.
