[0040] For details, please refer to Figure 1 and Figure 2 The present application provides a lens housing assembly, which may include a lens assembly 10 and a housing assembly 20. The lens assembly 10 includes a lens body 11, a lens housing 12, and a seal 13. The lens housing 12 is formed by injection molding on the outside of the lens body 11. The lens housing 12 includes a fixing portion 121 for connecting to the lens body 11 and a mounting portion 122 connected to the fixing portion 121. The seal 13 is formed by injection molding on the outside of the mounting portion 122. The housing assembly 20 includes a housing body 21 and a mating portion 22 connected to the housing body 21. The housing body 21 is fixedly connected to the lens housing 12. The seal 13 is interference fit with the mating portion 22 to seal the gap between the mating portion 22 and the mounting portion 122.
[0041] It can be understood that the lens housing 12 is an injection molded rubber-coated component located on the outside of the lens body 11, and the seal 13 is an injection molded rubber-coated component located on the outside of the mounting portion 122. The injection molded rubber-coated components can be formed on the outside of the lens body 11 and the outside of the mounting portion 122 by injection molding, thereby forming an integrated lens assembly 10. The lens assembly 10 can simplify the assembly process of the seal 13, lower the assembly cost, and the sealing structure between the lens assembly 10 and the housing assembly 20 is more stable and reliable.
[0042] Alternatively, if Figure 3a As shown, in the first example of the lens housing assembly of the present application, the outer side of the mounting portion 122 is recessed inward to form a mounting groove 1221, and the seal 13 is located in the mounting groove 1221. In other words, when the lens housing 12 is fixedly connected to the housing assembly 20, the seal 13 abuts against the inner side of the matching portion 22 to form a side pressure seal. The seal 13 is received in the mounting groove 1221, which can reduce the lateral size of the lens housing assembly, which is conducive to miniaturization of the camera module.
[0043] Alternatively, if Figure 3b As shown, in the second example of the lens housing assembly of the present application, the inner side of the mating portion 22 is recessed toward the outside to form a mating groove 221, and the sealing member 13 abuts against the bottom of the mating groove 221. In other words, when the lens housing 12 is fixedly connected to the housing assembly 20, it is inserted into the mating groove 221 and abuts against the bottom of the mating groove 221, thereby forming a side pressure seal. The sealing member 13 is received in the mating groove 221, which can reduce the lateral size of the lens housing assembly, which is conducive to miniaturization of the camera module.
[0044] Alternatively, if Figure 3c As shown, in the third example of the lens housing assembly of the present application, the mounting portion 122 includes a first step portion 1222 connected to the lens body 11 and a second step portion 1223 extending downward from the first step portion 1222, the outer diameter of the second step portion 1223 is smaller than the outer diameter of the first step portion 1222, and the seal 13 is fixed to the outer side of the second step portion 1223. When the lens housing 12 is fixedly connected to the housing assembly 20, the seal 13 abuts against the matching portion 22, thereby forming a side pressure seal. In this way, an escape space for accommodating the seal 13 can be formed on the outer side of the second step portion 1223, thereby reducing the lateral size of the lens housing assembly, which is conducive to miniaturization of the camera module.
[0045] Alternatively, if Figure 3dAs shown, in the fourth example of the lens housing assembly of the present application, the matching portion 22 includes a third step portion 222 connected to the housing body 21 and a fourth step portion 223 extending upward from the third step portion 222, the inner diameter of the third step portion 222 is smaller than the inner diameter of the fourth step portion 223, and the seal 13 abuts against the inner side of the fourth step portion 223. In this way, an escape space for accommodating the seal 13 can be formed on the inner side of the fourth step portion 223, thereby reducing the lateral size of the lens housing assembly, which is conducive to miniaturization of the camera module.
[0046] Optionally, in one embodiment, the lens body 11 is made of metal material or plastic material.
[0047] Optionally, the cross-sectional shape of the sealing member 13 may be circular or irregular, such as Figure 4a As shown, in the first example of the seal of the lens housing assembly of the present application, the cross section of the seal 13 is circular. Such a configuration makes the structure of the seal 13 simpler and easier to encapsulate and inject.
[0048] Alternatively, if Figure 4b and Figure 4c As shown, in the second example and the third example of the seal of the lens housing assembly of the present application, the seal 13 includes a sealing body 131 and a sealing portion 132 extending obliquely outward from the upper end or the lower end of the sealing body 131, the sealing body 131 is fixed to the mounting portion 122 by injection molding, and the sealing portion 132 abuts against the matching portion 22 to form a side pressure seal. With such a configuration, when the lens housing 12 and the housing assembly 20 are assembled, the sealing portion 132 can be bent toward the sealing body 131, so that the mounting portion 122 and the seal 13 can be more easily installed between the matching portion 22, reducing the difficulty of assembling the camera module.
[0049] Alternatively, if Figure 4d , Figure 4e , Figure 4f and Figure 4g As shown, in the fourth example, the fifth example, the sixth example and the seventh example of the seal of the lens housing assembly of the present application, the seal 13 includes a sealing body 131 and at least one sealing protrusion 133 convexly arranged on the outer side of the sealing body 131, the sealing body 131 is fixed to the mounting portion 122 by injection molding, and the sealing protrusion 133 abuts against the matching portion 22. In this way, the sealing protrusion 133 can cooperate with the inner side surface of the matching portion 22 to form multiple sealing points, thereby enhancing the sealing ability of the seal 13.
[0050] Optionally, the outer side surface of the sealing protrusion 133 is arc-shaped or pointed, and the arc-shaped sealing protrusion and the pointed sealing protrusion can be freely combined, such as Figure 4d As shown, the seal 13 includes an arc-shaped sealing protrusion, such as Figure 4e As shown, the seal 13 includes two arc-shaped sealing protrusions, such as Figure 4f As shown, the sealing member 13 includes an arc-shaped sealing protrusion and a pointed sealing protrusion. Figure 4g As shown, the seal 13 includes two pointed sealing protrusions. Such arrangement can enhance the deformation capability of the sealing protrusions 133, thereby enhancing the sealing capability of the seal 13.
[0051] It is worth noting that the seal 13 can be directly formed on the lens housing 12 by liquid silicone injection molding process, or can be fixed to the lens housing 12 by gluing.
[0052] In particular, if Figure 1 As shown, in one embodiment, the lens housing 12 has a plurality of hook grooves 123, and the housing assembly 20 includes a plurality of hooks 23 connected to the housing body 21, and the plurality of hooks 23 are respectively clamped in the plurality of hook grooves 123. In this way, the lens assembly 10 and the housing assembly 20 are fixed by clamping the hooks 23, eliminating the steps of assembling screws or adding glue, and simplifying the assembly steps of the camera module.
[0053] Optionally, in one embodiment, the housing body 21 and the hook 23 are integrally formed, and the hook 23 is in a straight edge state before the lens body 11 and the housing body 21 are assembled. When the lens body 11 and the housing body 21 are assembled, the hook 23 is bent into the hook groove 123.
[0054] Furthermore, the present application also provides a camera module, comprising: a module body 30 and a lens housing assembly as described in any one of the above items, wherein the module body 30 is mounted on the lens housing assembly. When assembling the camera module, it is only necessary to first bond the module body 30 to the housing assembly 20 through the AA process, and then snap-fit the housing assembly 20 to the lens assembly 10. The entire assembly process can be completed in only two steps, with high assembly efficiency and good yield, which is conducive to the miniaturization and simplification of the camera module.
[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0056] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
