In addition, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0030] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0031] Reference is made below Figures 1-5 The camera module 10 according to the embodiment of the present application is described.

[0032] As Figures 1-5 shown, the camera module 10 according to the embodiment of the present application comprises a motor housing 1 and a lens seat 2.

[0033] Specifically, referring to Figures 1-5 , one side of the motor housing 1 has a mounting groove 11, and a first positioning protrusion 12 is arranged on the bottom wall of the mounting groove 11. The lens seat 2 is arranged in the mounting groove 11, and one end of the lens seat 2 facing the bottom wall of the mounting groove 11 is provided with a first positioning groove 21 matched with the first positioning protrusion 12. Wherein, the motor can be an anti-shake motor or a focusing motor. After the motor housing 1 and the lens seat 2 are preliminarily positioned, they are locked to form an integral body, so that the motor housing 1 can drive the lens seat 2 to move, and the lens seat 2 is relatively fixed with the lens, thereby driving the lens to move to realize focusing or anti-shake function of the lens.

[0034] It can be understood that if the first positioning protrusion 12 is not arranged on the bottom wall of the mounting groove 11, the automatic equipment has no reference point, and the lens seat 2 cannot be accurately installed to the preset position, so that the automatic assembly of the camera module 10 is difficult to realize. In the present application, the first positioning protrusion 12 is arranged on the bottom wall of the mounting groove 11, so that the first positioning protrusion 12 can serve as a reference point for the automatic equipment. The precise positioning between the lens seat 2 and the motor housing 1 is realized through the positioning device (such as Active Alignment, active alignment equipment) on the automatic equipment, which on the one hand realizes the assembly of the motor housing 1 and the lens seat 2 through the automatic equipment, reduces the labor and improves the efficiency, and on the other hand is also conducive to the precise assembly and locking between the lens seat 2 and the motor housing 1.

[0035] Further, as shown in Figures 1-5 , the cross-sectional area of the first positioning protrusion 12 gradually increases in the direction from the slot opening of the mounting groove 11 to the bottom wall of the mounting groove 11, and / or the cross-sectional area of the first positioning groove 21 gradually increases in the direction from the bottom wall of the first positioning groove 21 to the slot opening of the first positioning groove 21.

[0036] For example, in the present application, the cross-sectional area of the first positioning protrusion 12 gradually increases in the direction from the slot opening of the mounting groove 11 to the bottom wall of the mounting groove 11, and the cross-sectional area of the first positioning groove 21 gradually increases in the direction from the bottom wall of the first positioning groove 21 to the slot opening of the first positioning groove 21. However, the present application is not limited thereto, and the cross-sectional area of the first positioning protrusion 12 can gradually increase in the direction from the slot opening of the mounting groove 11 to the bottom wall of the mounting groove 11, and the cross-sectional area of the first positioning groove 21 can remain unchanged in the direction from the bottom wall of the first positioning groove 21 to the slot opening of the first positioning groove 21. Alternatively, the cross-sectional area of the first positioning protrusion 12 can remain unchanged in the direction from the slot opening of the mounting groove 11 to the bottom wall of the mounting groove 11, and the cross-sectional area of the first positioning groove 21 can gradually increase in the direction from the bottom wall of the first positioning groove 21 to the slot opening of the first positioning groove 21.

[0037] It should be noted that, in any case, the cross-sectional area of the first positioning protrusion 12 near the end of the bottom wall of the mounting groove 11 is equal to or slightly smaller than the cross-sectional area of the slot of the first positioning groove 21, so that on the one hand, the first positioning protrusion 12 can be completely inserted into the first positioning groove 21, avoiding the lens seat 2 from being warped, and on the other hand, the first positioning protrusion 12 can not shake in the first positioning groove 21.

[0038] When the cross-sectional area of the first positioning protrusion 12 gradually increases along the direction from the slot of the mounting groove 11 to the bottom wall of the mounting groove 11, and the cross-sectional area of the first positioning groove 21 gradually increases along the direction from the bottom wall of the first positioning groove 21 to the slot of the first positioning groove 21, the cross-sectional area of the side of the first positioning protrusion 12 away from the bottom wall of the mounting groove 11 is the smallest, and the cross-sectional area of the slot of the first positioning groove 21 is the largest. Thus, when the first positioning protrusion 12 just enters the first positioning groove 21, the first positioning protrusion 12 can have a certain offset from the central axis of the first positioning groove 21, thereby increasing the allowable error of the first positioning protrusion 12 when it is initially installed into the first positioning groove 21, reducing the number of installation failures, and improving the installation efficiency. The remaining cases are similar to the above case, which will not be described in detail here.

[0039] According to the camera module 10 of the embodiment of the utility model, the side of the motor shell 1 has the mounting groove 11, the first positioning protrusion 12 is arranged on the bottom wall of the mounting groove 11, the lens seat 2 is arranged in the mounting groove 11, the end of the lens seat 2 facing the bottom wall of the mounting groove 11 is provided with the first positioning groove 21 matched with the first positioning protrusion 12, so that the first positioning protrusion 12 can be used as a reference point of the automatic equipment, on the one hand, the motor shell 1 and the lens seat 2 can be assembled by automatic equipment, reducing the labor and improving the efficiency, on the other hand, it is also conducive to the accurate assembly and locking between the lens seat 2 and the motor shell 1. Meanwhile, the cross-sectional area of the first positioning protrusion 12 gradually increases along the direction from the slot of the mounting groove 11 to the bottom wall of the mounting groove 11, and / or the cross-sectional area of the first positioning groove 21 gradually increases along the direction from the bottom wall of the first positioning groove 21 to the slot of the first positioning groove 21, so that when the first positioning protrusion 12 just enters the first positioning groove 21, the first positioning protrusion 12 can have a certain offset from the central axis of the first positioning groove 21, thereby increasing the allowable error of the first positioning protrusion 12 when it is initially installed into the first positioning groove 21, reducing the number of installation failures, and improving the installation efficiency.

[0040] In some embodiments of the utility model, as shown in Figure 3 and Figure 4 , the lens seat 2 is spaced apart from the inner circumferential wall of the mounting groove 11. Thus, the installation interference when the lens seat 2 is installed into the mounting groove 11 can be avoided, and the positioning assembly of the lens seat 2 and the motor shell 1 is facilitated.

[0041] In some embodiments of the utility model, as shown in Figure 4 and Figure 5 The height of the first positioning protrusion 12 is less than the depth of the first positioning groove 21. Thus, the situation that the first positioning protrusion 12 lifts the lens seat 2 due to tolerance can be avoided, and the reliability of the positioning of the lens seat 2 and the motor housing 1 is further improved.

[0042] In some embodiments of the utility model, as shown in Figure 4 and Figure 5 In the direction from the slot opening of the mounting groove 11 to the bottom wall of the mounting groove 11, the peripheral wall of the first positioning protrusion 12 extends obliquely in the direction away from the center of the first positioning protrusion 12. Thus, the cross-sectional area of the first positioning protrusion 12 gradually increases in the direction from the slot opening of the mounting groove 11 to the bottom wall of the mounting groove 11.

[0043] In some embodiments of the utility model, as shown in Figure 4 and Figure 5 In the direction from the bottom wall of the first positioning groove 21 to the slot opening of the first positioning groove 21, the inner peripheral wall of the first positioning groove 21 extends obliquely in the direction away from the center of the first positioning groove 21. Thus, the cross-sectional area of the first positioning groove 21 gradually increases in the direction from the bottom wall of the first positioning groove 21 to the slot opening of the first positioning groove 21. In addition, the inner peripheral wall of the first positioning groove 21 can also guide the first positioning protrusion 12, making it easier for the first positioning protrusion 12 to extend into the first positioning groove 21, thereby further improving the positioning and assembly efficiency of the lens seat 2 and the motor housing 1.

[0044] In some embodiments of the utility model, as shown in Figure 4 and Figure 5 The end surface of the first positioning protrusion 12 away from the bottom wall of the mounting groove 11 is a plane parallel to the bottom wall of the mounting groove 11. It can be understood that if the end of the first positioning protrusion 12 away from the bottom wall of the mounting groove 11 is conical, it is easy to damage the lens seat 2 during positioning and assembly. Thus, by making the end surface of the first positioning protrusion 12 away from the bottom wall of the mounting groove 11 a plane parallel to the bottom wall of the mounting groove 11, damage to the lens seat 2 can be avoided.

[0045] In some embodiments of the utility model, the motor housing 1 and the lens seat 2 are connected by gluing, for example, after positioning, the motor housing 1 and the lens seat 2 are glued, thereby improving the reliability of the positioning and locking between the motor housing 1 and the lens seat 2.

[0046] In some embodiments of the utility model, second positioning groove (not shown) is equipped on the bottom wall of mounting groove 11, one end of lens seat 2 towards the bottom wall of mounting groove 11 has second positioning protrusion (not shown) matched with second positioning groove, along the direction from the slot of mounting groove 11 to the bottom wall of mounting groove 11, the cross-sectional area of second positioning groove gradually reduces.And / or, along the direction from the slot of mounting groove 11 to the bottom wall of mounting groove 11, the cross-sectional area of second positioning protrusion gradually reduces.

[0047] Need to explain is that, can be along the direction from the slot of mounting groove 11 to the bottom wall of mounting groove 11, the cross-sectional area of second positioning groove gradually reduces, and the cross-sectional area of second positioning protrusion gradually reduces simultaneously.Also can be along the direction from the slot of mounting groove 11 to the bottom wall of mounting groove 11, the cross-sectional area of second positioning groove gradually reduces, and the cross-sectional area of second positioning protrusion is not changed.Also can be along the direction from the slot of mounting groove 11 to the bottom wall of mounting groove 11, the cross-sectional area of second positioning groove is not changed, and the cross-sectional area of second positioning protrusion gradually reduces.

[0048] Need to explain is that, whichever case, the cross-sectional area of the end of second positioning protrusion away from the bottom wall of mounting groove 11 is equal to or slightly smaller than the cross-sectional area of the slot of second positioning groove, thereby on the one hand can guarantee that second positioning protrusion can be completely inserted into second positioning groove, avoids lens seat warping, on the other hand can guarantee that second positioning protrusion can not be shaken in second positioning groove.

[0049] When along the direction from the slot of mounting groove 11 to the bottom wall of mounting groove 11, the cross-sectional area of second positioning groove gradually reduces, and the cross-sectional area of second positioning protrusion gradually reduces, the cross-sectional area of the side of second positioning protrusion towards the bottom wall of mounting groove 11 is minimum, and the cross-sectional area at the slot of second positioning groove is maximum, thereby, when second positioning protrusion just enters second positioning groove, second positioning protrusion and the central axis of second positioning groove can have a certain offset, thereby increasing the allowable error of second positioning protrusion when just starting to be installed to second positioning groove, reducing the number of installation failures, improving installation efficiency.The remaining cases are similar to the above case, and will not be described in detail here.

[0050] In some embodiments of the utility model, as shown in Figure 1 And Figure 2 The first positioning protrusion 12 is spaced apart, and the first positioning groove 21 is one-to-one corresponding to the plurality of first positioning protrusions 12. Thus, the positioning reliability and accuracy between the lens seat 2 and the motor housing 1 are improved. For example, in the utility model, the first positioning protrusion 12 is 4, and the first positioning groove 21 is also 4, but the utility model is not limited to this. The first positioning groove 21 can also be other quantities, such as 2, 6, 8, or 10, etc.

[0051] In some embodiments of the utility model, as shown in Figure 1 And Figure 2 As shown, a plurality of first positioning protrusions 12 are symmetrically distributed. It can be understood that the lens seat 2 is a symmetric structure, thereby making the lens seat 2 can have multiple free plane installation angles, further improving the positioning and assembly efficiency of the lens seat 2 and the motor housing 1.

[0052] For example, in the utility model, the mounting groove 11 is located on one side of the motor housing 1 in the thickness direction, and a plurality of first positioning protrusions 12 are symmetrically arranged along the symmetric axis extending in the length direction and the width direction of the motor housing 1.

[0053] In some embodiments of the utility model, as shown in Figure 1 And Figure 3 As shown, the cross-sectional outer contour shape of the mounting groove 11 is the same as the cross-sectional outer contour shape of the lens seat 2. Therefore, the lens seat 2 can be better limited.

[0054] For example, in the example shown in 1-5, the cross-sectional outer contour shape of the mounting groove 11 is rectangular, and the cross-sectional outer contour shape of the lens seat 2 is also rectangular, but the utility model is not limited to this, for example, the cross-sectional outer contour shape of the mounting groove 11 can also be circular, and the cross-sectional outer contour shape of the lens seat 2 is also circular.

Meanwhile, the cross-sectional area of the first positioning protrusion 12 gradually increases in the direction from the slot of the mounting groove 11 to the bottom wall of the mounting groove 11, and / or the cross-sectional area of the first positioning groove 21 gradually increases in the direction from the bottom wall of the first positioning groove 21 to the slot of the first positioning groove 21, so that when the first positioning protrusion 12 just enters the first positioning groove 21, the first positioning protrusion 12 can have a certain offset amount from the central axis of the first positioning groove 21, thereby increasing the allowable error of the first positioning protrusion 12 when being initially installed into the first positioning groove 21, reducing the number of installation positioning failures, and improving the installation positioning efficiency.
